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 what we pay for deposits and other sources of funding. The direction and level of interest rates are important factors in our earnings. Net interest margin is calculated by dividing annualized net interest 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.

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 $7.9$10.7 million and $7.6$7.9 million for the three months ended September 30, 20202021 and 2019,2020, respectively.

Provision for Credit Losses

The Corporation adopted ASU No. 2016-13, “Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments” (ASU 2016-13) on January 1, 2020, which significantly changed 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. 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 $0.5$13.0 million provision forrelease of credit lossesreserves in the current quarter, as compared to a credit provision of $7.0$0.5 million in the prior-year quarter. 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 increasedecrease in the collective basis reserve was driven by continued improvements in projected economic conditions and portfolio credit quality, partially offset by portfolio growth. Decreases in the collective basis reserve were primarily in the commercial and institutional and commercial real estate portfolios.
The provision in the prior-year quarter was primarily due to an increase in the reserve evaluated on a collective basis driven by projected economic conditions at the time, resulting from the ongoing COVID-19 pandemic and related market and economic impacts, with increases in the private client, commercial real estate, and residential real estate portfolios, partially offset by a decrease in the commercial and institutional portfolio. The overall increase in the reserve on a collective basis was partially offset by a decrease in the reserve associated with loans evaluated on an individual basis. The credit provision in the prior-year quarter was primarily driven by a decrease in the specific allowance attributable to the residential real estate portfolio and a slight decrease in the inherent allowance under the previous “incurred loss” model.

Net Interest Income
Net Interest Income is defined as the total of Interest Income and amortized fees on earning assets, less Interest Expense on deposits and borrowed funds, adjusted for the impact of interest-related hedging activity. Earning assets—including Federal Funds Sold, Securities Purchased under Agreements to Resell, Interest-Bearing Due From Banks, Federal Reserve and Other Central Bank Deposits and Other, Securities, and Loans and Leases—are financed by a large base of interest-bearing funds that include client deposits, short-term borrowings, Senior Notes and Long-Term Debt. Short-term borrowings include Federal Funds Purchased, Securities Sold Under Agreements to Repurchase, and Other Borrowings. Earning assets are also funded by noninterest-related funds, which include demand deposits and stockholders’ equity. Net Interest Income is subject to variations in the level and mix of earning assets and interest-bearing funds and their relative sensitivity to interest rates. In addition, the levels of nonaccruing assets and client compensating deposit balances used to pay for services impact Net Interest Income.
Net interest margin is the difference between what we earn on our assets and what we pay for deposits and other sources of funding. The direction and level of interest rates are important factors in our earnings. Net interest margin is calculated by dividing annualized Net Interest Income by average interest-earning assets.
Net Interest Income stated on a fully taxable equivalent (FTE) basis is a non-generally accepted accounting principle (GAAP) financial measure that facilitates the analysis of asset yields. Management believes an FTE presentation provides a clearer indication of net interest margins for comparative purposes. When adjusted to an FTE basis, yields on taxable, nontaxable, and partially taxable assets are comparable; however, the adjustment to an FTE basis has no impact on Net Income. A reconciliation of Net Interest Income on a GAAP basis to Net Interest Income on an FTE basis is provided on page 32.

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 $10.7 million and $7.9 million for the three months ended September 30, 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 32. Net interest margin is calculated by dividing annualized Net Interest Income by average interest-earning assets.
Interest revenue on cash collateral positions is reported above in Interest-Bearing Due from and Deposits with Banks and in Loans and Leases. Interest Expense on cash collateral positions is reported above in Non-U.S. Offices Interest-Bearing Deposits. Related cash collateral received from and deposited with derivative counterparties is recorded net of the associated derivative contract in Other Assets and Other Liabilities, respectively.
Net Interest Income, stated on a FTE basis, increased $126.0 million,from the prior-year quarter, primarily due to higher average earning assets, partially offset by a lower net interest margin.Average earning assets increased from the prior-year quarter, primarily due to higher levels of short-term interest-bearing deposits with banks and loans. Funding of the balance sheet reflected higher levels of client deposits.
The net interest margin on an FTE basis decreased from the prior-year quarter, primarily driven by lower average interest rates, partially offset by favorable balance sheet volume and mix shift. Low levels of market interest rates are expected to continue to impact our net interest income.
Federal Reserve and Other Central Bank Deposits and Other averaged $40.5 billion and increased $8.9 billion, or 4%28%, from $3.07$31.6 billion in the prior-year period to $3.20quarter, resulting from significant deposit inflows. The higher level of client deposits were primarily placed with the Federal Reserve and other central banks and in loans. Average Securities were $59.0 billion and increased $923.6 million, or 2%, from $58.1 billion, in the prior-year quarter and include certain community development investments, Federal Home Loan Bank stock, and Federal Reserve stock of $936.9 million, $160.1 million and $70.0 million, respectively, which are recorded in Other Assets on the consolidated balance sheets. Average taxable Securities were $56.4 billion in the current period,quarter and $52.8 billion in the prior-year quarter.

$5.2 billion in the prior-year quarter. Interest-Bearing Due from and Deposits with Banks averaged $5.2 billion in the current quarter and $4.8 billion in the prior-year quarter.
Loans and Leases averaged $38.4 billion and increased $5.3 billion, or 16%, from $33.1 billion in the prior-year quarter, primarily reflecting higher levels of private client, commercial real estate, commercial and institutional, non-U.S., and residential real estate loans. Private client loans averaged $14.5 billion and increased $2.8 billion, or 23%, from $11.7 billion for the prior-year quarter. Commercial real estate loans averaged $4.1 billion and increased $795.2 million, or 24%, from $3.3 billion for the prior-year quarter. Commercial and institutional loans averaged $10.8 billion and increased $766.0 million, or 8%, from $10.0 billion for the prior-year quarter. Non-U.S. loans averaged $2.4 billion and increased $764.7 million or 46%, from $1.7 billion for the prior-year quarter. Residential real estate loans averaged $6.2 billion and increased $75.4 million, or 1%, from $6.1 billion for the prior-year quarter.
Northern Trust utilizes a diverse mix of funding sources. Average Interest-Bearing Deposits increased $12.0 billion, or 14%, to an average of $99.6 billion in the current quarter from $87.6 billion in the prior-year quarter. Other Average Interest-Related Funds decreased $1.5 billion, or 13%, to an average of $10.3 billion in the current quarter from $11.8 billion in the prior-year quarter. The balances within short-term borrowing classifications vary based on funding requirements and strategies, interest rate levels, changes in the volume of lower-cost deposit sources, and the availability of collateral to secure these borrowings. Average net noninterest-related funds increased $4.1 billion, or 14%, to $34.1 billion in the current quarter from $30.0 billion in the prior-year quarter, primarily resulting from higher equipmentlevels of Demand and softwareOther Noninterest-Bearing Deposits.
Interest expense other operating expense, compensation expense, employee benefits expensefor Interest-Bearing Deposits in the current quarter was driven by low and occupancy expense,negative interest rates for Non-U.S. Offices Interest-Bearing Deposits and low interest rates on domestic Interest-Bearing Deposits. Average Non-U.S. Offices Interest-Bearing Deposits comprised 71% of total average Interest-Bearing Deposits for the three months ended September 30, 2021.
Provision for Credit Losses
There was a $13.0 million release of credit reserves in the current quarter, as compared to a provision of $0.5 million in the prior-year quarter. The release 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 improvements in projected economic conditions and portfolio credit quality, partially offset by lower outside services expense. portfolio growth. Decreases in the collective basis reserve were primarily in the commercial and institutional and commercial real estate portfolios.
The increaseprovision in other operating expensethe prior-year quarter was primarily due to an increase in the reserve evaluated on a collective basis driven by projected economic conditions at the time, resulting from the ongoing COVID-19 pandemic and related market and economic impacts, with increases in the private client, commercial real estate, and residential real estate portfolios, partially offset by a decrease in the commercial and institutional portfolio. The overall increase in the reserve on a collective basis was partially offset by a decrease in the reserve associated with loans evaluated on an individual basis.
Net recoveries in the current quarter were $1.1 million, reflecting $1.1 million of recoveries and de minimis charge-offs. The prior-year quarter included $0.4 million of net recoveries, reflecting $1.2 million of recoveries and $0.8 million of charge-offs. Nonaccrual assets of $141.2 million increased $42.3 million, or 43%, from $98.9 million at the end of the prior-year quarter.

Noninterest Expense (continued)
Employee Benefits expense increased compared to the prior-year quarter, primarily due to a pension settlement charge in the current quarter and higher medical costs.
Outside Services expense increased compared to the prior-year quarter, primarily due to higher third-party advisory fees, technical services costs and sub-custodian expenses.
Equipment and Software expense increased compared to the prior-year quarter, primarily due to higher software support and rental costs and higher amortization.
Other Operating Expense decreased compared to the prior-year quarter, primarily due to lower charges associated with account servicing activities and a decline in other miscellaneous expenses, including lower supplemental compensation plan expense. The lower supplemental compensation plan expense resulted in a related decrease in miscellaneous income reported in noninterest income. The account servicing activities in the prior-year quarter included a $43.4 million charge related to a corporate action processing error.

Net Interest Income
Net Interest Income is defined as the total of Interest Income and amortized fees on earning assets, less Interest Expense on deposits and borrowed funds, adjusted for the impact of interest-related hedging activity. Earning assets—including Federal Funds Sold, Securities Purchased under Agreements to Resell, Interest-Bearing Due From Banks, Federal Reserve and Other Central Bank Deposits and Other, Securities, and Loans and Leases—are financed by a large base of interest-bearing funds that include client deposits, short-term borrowings, Senior Notes and Long-Term Debt. Short-term borrowings include Federal Funds Purchased, Securities Sold Under Agreements to Repurchase, and Other Borrowings. Earning assets are also funded by noninterest-related funds, which include demand deposits and stockholders’ equity. Net Interest Income is subject to variations in the level and mix of earning assets and interest-bearing funds and their relative sensitivity to interest rates. In addition, the levels of nonaccruing assets and client compensating deposit balances used to pay for services impact Net Interest Income.
Net interest margin is the difference between what we earn on our assets and what we pay for deposits and other sources of funding. The direction and level of interest rates are important factors in our earnings. Net interest margin is calculated by dividing annualized Net Interest Income by average interest-earning assets.
Net Interest Income stated on a fully taxable equivalent (FTE) basis is a non-generally accepted accounting principle (GAAP) financial measure that facilitates the analysis of asset yields. Management believes an FTE presentation provides a clearer indication of net interest margins for comparative purposes. When adjusted to an FTE basis, yields on taxable, nontaxable, and partially taxable assets are comparable; however, the adjustment to an FTE basis has no impact on Net Income. A reconciliation of Net Interest Income on a GAAP basis to Net Interest Income on an FTE basis is provided on page 32.

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 $23.7$10.7 million and $23.1$7.9 million for the three months ended September 30, 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 32. Net interest margin is calculated by dividing annualized Net Interest Income by average interest-earning assets.
Interest revenue on cash collateral positions is reported above in Interest-Bearing Due from and Deposits with Banks and in Loans and Leases. Interest Expense on cash collateral positions is reported above in Non-U.S. Offices Interest-Bearing Deposits. Related cash collateral received from and deposited with derivative counterparties is recorded net of the associated derivative contract in Other Assets and Other Liabilities, respectively.
Net Interest Income, stated on a FTE basis, increased from the prior-year quarter, primarily due to higher average earning assets, partially offset by a lower net interest margin.Average earning assets increased from the prior-year quarter, primarily due to higher levels of short-term interest-bearing deposits with banks and loans. Funding of the balance sheet reflected higher levels of client deposits.
The net interest margin on an FTE basis decreased from the prior-year quarter, primarily driven by lower average interest rates, partially offset by favorable balance sheet volume and mix shift. Low levels of market interest rates are expected to continue to impact our net interest income.
Federal Reserve and Other Central Bank Deposits and Other averaged $40.5 billion and increased $8.9 billion, or 28%, from $31.6 billion in the prior-year quarter, resulting from significant deposit inflows. The higher level of client deposits were primarily placed with the Federal Reserve and other central banks and in loans. Average Securities were $59.0 billion and increased $923.6 million, or 2%, from $58.1 billion, in the prior-year quarter and include certain community development investments, Federal Home Loan Bank stock, and Federal Reserve stock of $936.9 million, $160.1 million and $70.0 million, respectively, which are recorded in Other Assets on the consolidated balance sheets. Average taxable Securities were $56.4 billion in the current quarter and $52.8 billion in the prior-year quarter. Average nontaxable Securities, which represent securities that are primarily exempt from U.S. federal and state income taxes, were $2.6 billion in the current quarter and

THIRD QUARTER CONSOLIDATED RESULTS OF OPERATIONS (continued)
Net Interest Income (continued)
$5.2 billion in the prior-year quarter. Interest-Bearing Due from and Deposits with Banks averaged $5.2 billion in the current quarter and $4.8 billion in the prior-year quarter.
Loans and Leases averaged $38.4 billion and increased $5.3 billion, or 16%, from $33.1 billion in the prior-year quarter, primarily reflecting higher levels of private client, commercial real estate, commercial and institutional, non-U.S., and residential real estate loans. Private client loans averaged $14.5 billion and increased $2.8 billion, or 23%, from $11.7 billion for the prior-year quarter. Commercial real estate loans averaged $4.1 billion and increased $795.2 million, or 24%, from $3.3 billion for the prior-year quarter. Commercial and institutional loans averaged $10.8 billion and increased $766.0 million, or 8%, from $10.0 billion for the prior-year quarter. Non-U.S. loans averaged $2.4 billion and increased $764.7 million or 46%, from $1.7 billion for the prior-year quarter. Residential real estate loans averaged $6.2 billion and increased $75.4 million, or 1%, from $6.1 billion for the prior-year quarter.
Northern Trust utilizes a diverse mix of funding sources. Average Interest-Bearing Deposits increased $12.0 billion, or 14%, to an average of $99.6 billion in the current quarter from $87.6 billion in the prior-year quarter. Other Average Interest-Related Funds decreased $1.5 billion, or 13%, to an average of $10.3 billion in the current quarter from $11.8 billion in the prior-year quarter. The balances within short-term borrowing classifications vary based on funding requirements and strategies, interest rate levels, changes in the volume of lower-cost deposit sources, and the availability of collateral to secure these borrowings. Average net noninterest-related funds increased $4.1 billion, or 14%, to $34.1 billion in the current quarter from $30.0 billion in the prior-year quarter, primarily resulting from higher levels of Demand and Other Noninterest-Bearing Deposits.
Interest expense for Interest-Bearing Deposits in the current quarter was driven by low and negative interest rates for Non-U.S. Offices Interest-Bearing Deposits and low interest rates on domestic Interest-Bearing Deposits. Average Non-U.S. Offices Interest-Bearing Deposits comprised 71% of total average Interest-Bearing Deposits for the three months ended September 30, 2021.
Provision for Credit Losses
There was a $13.0 million release of credit reserves in the current quarter, as compared to a provision of $0.5 million in the prior-year quarter. The release 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 improvements in projected economic conditions and portfolio credit quality, partially offset by portfolio growth. Decreases in the collective basis reserve were primarily in the commercial and institutional and commercial real estate portfolios.
The provision in the prior-year quarter was primarily due to an increase in the reserve evaluated on a collective basis driven by projected economic conditions at the time, resulting from the ongoing COVID-19 pandemic and related market and economic impacts, with increases in the private client, commercial real estate, and residential real estate portfolios, partially offset by a decrease in the commercial and institutional portfolio. The overall increase in the reserve on a collective basis was partially offset by a decrease in the reserve associated with loans evaluated on an individual basis.
Net recoveries in the current quarter were $1.1 million, reflecting $1.1 million of recoveries and de minimis charge-offs. The prior-year quarter included $0.4 million of net recoveries, reflecting $1.2 million of recoveries and $0.8 million of charge-offs. Nonaccrual assets of $141.2 million increased $42.3 million, or 43%, from $98.9 million at the end of the prior-year quarter.

THIRD QUARTER CONSOLIDATED RESULTS OF OPERATIONS (continued)
Noninterest Expense (continued)
Employee Benefits expense increased compared to the prior-year quarter, primarily due to a pension settlement charge in the current quarter and higher medical costs.
Outside Services expense increased compared to the prior-year quarter, primarily due to higher third-party advisory fees, technical services costs and sub-custodian expenses.
Equipment and Software expense increased compared to the prior-year quarter, primarily due to higher software support and rental costs and higher amortization.
Other Operating Expense decreased compared to the prior-year quarter, primarily due to lower charges associated with account servicing activities and a decline in other miscellaneous expenses, including lower supplemental compensation plan expense. The lower supplemental compensation plan expense resulted in a related decrease in miscellaneous income reported in noninterest income. The account servicing activities in the prior-year quarter included a $43.4 million charge related to a corporate action processing error. Please refer to Note 17 — Other Operating Expense to the consolidated financial statements provided in Item 1. Consolidated Financial Statements (unaudited) for further detail.
Provision for Income Taxes
Income tax expense for the three months ended September 30, 2021 was $122.4 million, representing an effective tax rate of 23.6%, compared to $95.4 million in the prior-year quarter, representing an effective tax rate of 24.5%.
The effective tax rate decreased compared to the prior-year quarter primarily due to an increase in allocated tax credits related to community development projects and a lower net tax impact from international operations.
NINE-MONTH CONSOLIDATED RESULTS OF OPERATIONS
Overview of Financial Results
Net Income per diluted common share increased in the current period to $5.22 from $4.34 in the comparable prior-year period. Net income increased $170.5 million, or 18%, to $1.14 billion in the current period from $968.4 million in the prior-year period. Annualized return on average common equity was 13.7% in the current period and 12.0% in the prior-year period. The annualized return on average assets was 0.98% in the current period compared to 0.96% in the prior-year period.
Revenue for the nine months ended September 30, 2021 increased $218.6 million, or 5%, from $4.58 billion in the prior-year period to $4.80 billion in the current period.
Trust, Investment and Other Servicing Fees increased $281.2 million, or 9%, from $2.97 billion in the prior-year period to $3.25 billion in the current period, primarily driven by favorable markets, new business, and currency translation, partially offset by higher money market mutual fund fee waivers.
Other Noninterest Income increased $24.1 million, or 5% from $501.2 million in the prior-year period to $525.3 million in the current period, primarily driven by higher Other Operating Income and Security Commissions and Trading Income, partially offset by lower Foreign Exchange Trading Income.
Net Interest Income decreased $86.7 million, or 8%, to $1.02 billion in the current period from $1.11 billion in the prior-year period, primarily due to lower average interest rates, partially offset by an increase in average earning assets.
There was a $70.0 million release of credit reserves in the current period, as compared to a provision of $127.5 million in the prior-year period.
Noninterest Expense increased $169.8 million, or 5%, from $3.20 billion in the prior-year period to $3.37 billion in the current period, primarily attributable to higher Compensation, Outside Services, Equipment and Software expense and Employee Benefits, partially offset by lower Other Operating Expense and Occupancy.
The Provision for Income Taxes for the nine months ended September 30, 2021 totaled $361.6 million, representing an effective tax rate of 24.1%. The Provision for Income Taxes for the nine months ended September 30, 2020 totaled $285.8 million, representing an effective tax rate of 22.8%. The effective tax rate increased compared to the prior-year period primarily due to lower tax benefits related to share-based compensation, the deferred tax impact of the enacted increase in the UK statutory tax rate, and a prior-year-period tax benefit from dispositions of leveraged leases.

NINE-MONTH CONSOLIDATED RESULTS OF OPERATIONS (continued)
Trust, Investment and Other Servicing Fees
Beginning in the second quarter of 2020, 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 $206.7 million and $5.7 million of money market mutual fund fees for the nine months ended September 30, 2021 and 2020, respectively. 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 in the table below.

Custody and Fund Administration fees, the largest component of C&IS fees, increased primarily driven by favorable markets, new business, and favorable currency translation. Investment Management fees decreased primarily due to higher money market mutual fund fee waivers, partially offset by favorable markets and new business. Securities Lending fees decreased primarily driven by lower spreads, partially offset by higher volumes.
Wealth Management
Fee income in the regions (Central, East and West) increased primarily due to favorable markets, partially offset by higher money market mutual fund fee waivers. Global Family Office fee income increased primarily due to favorable markets and new business, partially offset by higher money market mutual fund fee waivers.

Security Commissions and Trading Income increased from the prior-year period, primarily due to higher core brokerage revenue, partially offset by lower revenue from interest rate swaps.
Other Operating Income increased from the prior-year period, primarily due to higher banking and credit-related service charges, distributions from investments in community development projects, and higher miscellaneous income, partially offset by higher expenses for existing swap agreements related to Visa Inc. Class B common shares. The higher miscellaneous income was primarily associated with a market value increase in the supplemental compensation plans, which also resulted in a related increase in supplemental compensation plan expense in Other Operating Expense.

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 $25.6 million and $23.7 million for the nine months ended September 30, 20202021 and 2019,2020, 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 35.32. Net interest margin is calculated by dividing annualized net interest income by average interest-earning assets.
Interest revenue on cash collateral positions is reported above within Interest-Bearing Due from and Deposits with Banks and within Loans and Leases. Interest expense on cash collateral positions is reported above within Non-U.S. Offices Interest-Bearing Deposits. Related cash collateral received from and deposited with derivative counterparties is recorded net of the associated derivative contract within Other Assets and Other Liabilities, respectively.

Net interest income,Interest Income, stated on an FTE basis, decreased from the prior-year period, primarily due to a lower netaverage interest margin,rates, partially offset by an increase in average earning assets. Average earning assets increased primarily due to higher levels of short-term interest-bearing deposits with banks, securities and loans. Funding of the balance sheet reflected higher levels of client deposits. The increase in average client deposit balance resulted from the large inflows experienced at the end of the first quarter caused by client reaction to current economic and market conditions. Average non-U.S. offices interest-bearing deposits comprised 71% of total average interest-bearing deposits for the nine months ended September 30, 2020.2021.
The net interest margin on an FTE basis decreased from the prior-year period, primarily due to lower average interest rates. Low levels of market interest rates are expected to continue to impact our net interest income.

Provision for Credit Losses
The Corporation adopted ASU No. 2016-13, “Financial Instruments—Credit Losses: MeasurementThere was a $70.0 million release of Credit Losses on Financial Instruments” (ASU 2016-13) on January 1, 2020, which significantly changed 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 by $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.

The provision for credit lossesreserves for the nine months ended September 30, 20202021, as compared to a provision of $127.5 million in the prior-year period. The release of credit reserves was $127.5 millionprimarily due to a decrease in the reserve evaluated on a collective basis, which relates to pooled financial assets sharing similar risk characteristics. The decrease in the collective basis reserve was driven by continued improvements in projected economic conditions and portfolio credit quality, partially offset by portfolio growth.
The provision in the prior-year period was primarily due to an increase in the reserve evaluated on a collective basis driven by downgrades in the portfolio and current and projected economic conditions at the time, both resulting from the ongoing COVID-19 pandemic and related market and economic impacts, with the largest increases in the commercial and institutional and commercial real estate portfolios. The provision for credit losses for the nine months ended September 30, 2019 wasIn addition, a credit provision of $13.5$13.7 million primarily driven by a decreaseincrease in the allowance for the residential real estate portfolio driven by reductions in outstanding loans and improved credit quality, partially offset by increases for the private client portfolio driven by lower credit quality, which resulted inlosses, with a corresponding cumulative effect adjustment to decrease retained earnings of $10.1 million, net decrease in the inherent allowance.of income taxes, was recorded on January 1, 2020 upon adoption of Accounting Standards Update (ASU) No. 2016-13, “Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments.”

The following table presents AUC/A 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-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.TABLE 4: ASSETS UNDER CUSTODY / ADMINISTRATION BY REPORTING SEGMENT

Net Interest Income
Net Interest Income is defined as the total of Interest Income and amortized fees on earning assets, less Interest Expense on deposits and borrowed funds, adjusted for the three-impact of interest-related hedging activity. Earning assets—including Federal Funds Sold, Securities Purchased under Agreements to Resell, Interest-Bearing Due From Banks, Federal Reserve and nine- month periods ended September 30, 2020Other Central Bank Deposits and 2019.Other, Securities, and Loans and Leases—are financed by a large base of interest-bearing funds that include client deposits, short-term borrowings, Senior Notes and Long-Term Debt. Short-term borrowings include Federal Funds Purchased, Securities Sold Under Agreements to Repurchase, and Other Borrowings. Earning assets are also funded by noninterest-related funds, which include demand deposits and stockholders’ equity. Net Interest Income is subject to variations in the level and mix of earning assets and interest-bearing funds and their relative sensitivity to interest rates. In addition, the levels of nonaccruing assets and client compensating deposit balances used to pay for services impact Net Interest Income.
TABLE 23: RESULTS OF REPORTING SEGMENTSNet interest margin is the difference between what we earn on our assets and what we pay for deposits and other sources of funding. The direction and level of interest rates are important factors in our earnings. Net interest margin is calculated by dividing annualized Net Interest Income by average interest-earning assets.

(1)Non-GAAP financial measuresNet Interest Income stated on a fully taxable equivalent (FTE) basis (FTE).is a non-generally accepted accounting principle (GAAP) financial measure that facilitates the analysis of asset yields. Management believes an FTE presentation provides a clearer indication of net interest margins for comparative purposes. When adjusted to an FTE basis, yields on taxable, nontaxable, and partially taxable assets are comparable; however, the adjustment to an FTE basis has no impact on Net Income. A reconciliation of Net Interest Income on a GAAP basis to Net Interest Income on an FTE basis is provided on page 32.

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

Notes:    Net Interest Income (FTE Adjusted), a non-GAAP financial measure, includes adjustments to a fully taxable equivalent basis for loans and securities. The adjustments are based on a federal income tax rate of 21.0%, where the rate is adjusted for applicable state income taxes, net of related federal tax benefit. Total consolidated includes FTEtaxable equivalent interest adjustments ofamounted to $10.7 million and $7.9 million for the three months ended September 30, 2021 and 2020, and $7.6 million for 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 32. Net interest margin is calculated by dividing annualized Net Interest Income by average interest-earning assets.
Interest revenue on cash collateral positions is reported above in Interest-Bearing Due from and Deposits with Banks and in Loans and Leases. Interest Expense on cash collateral positions is reported above in Non-U.S. Offices Interest-Bearing Deposits. Related cash collateral received from and deposited with derivative counterparties is recorded net of the associated derivative contract in Other Assets and Other Liabilities, respectively.
Net Interest Income, stated on a FTE basis, increased from the prior-year quarter, primarily due to higher average earning assets, partially offset by a lower net interest margin.Average earning assets increased from the prior-year quarter, primarily due to higher levels of short-term interest-bearing deposits with banks and loans. Funding of the balance sheet reflected higher levels of client deposits.
The net interest margin on an FTE basis decreased from the prior-year quarter, primarily driven by lower average interest rates, partially offset by favorable balance sheet volume and mix shift. Low levels of market interest rates are expected to continue to impact our net interest income.
Federal Reserve and Other Central Bank Deposits and Other averaged $40.5 billion and increased $8.9 billion, or 28%, from $31.6 billion in the prior-year quarter, resulting from significant deposit inflows. The higher level of client deposits were primarily placed with the Federal Reserve and other central banks and in loans. Average Securities were $59.0 billion and increased $923.6 million, or 2%, from $58.1 billion, in the prior-year quarter and include certain community development investments, Federal Home Loan Bank stock, and Federal Reserve stock of $936.9 million, $160.1 million and $70.0 million, respectively, which are recorded in Other Assets on the consolidated balance sheets. Average taxable Securities were $56.4 billion in the current quarter and $52.8 billion in the prior-year quarter. Average nontaxable Securities, which represent securities that are primarily exempt from U.S. federal and state income taxes, were $2.6 billion in the current quarter and

THIRD QUARTER CONSOLIDATED RESULTS OF OPERATIONS (continued)
Net Interest Income (continued)
$5.2 billion in the prior-year quarter. Interest-Bearing Due from and Deposits with Banks averaged $5.2 billion in the current quarter and $4.8 billion in the prior-year quarter.
Loans and Leases averaged $38.4 billion and increased $5.3 billion, or 16%, from $33.1 billion in the prior-year quarter, primarily reflecting higher levels of private client, commercial real estate, commercial and institutional, non-U.S., and residential real estate loans. Private client loans averaged $14.5 billion and increased $2.8 billion, or 23%, from $11.7 billion for the prior-year quarter. Commercial real estate loans averaged $4.1 billion and increased $795.2 million, or 24%, from $3.3 billion for the prior-year quarter. Commercial and institutional loans averaged $10.8 billion and increased $766.0 million, or 8%, from $10.0 billion for the prior-year quarter. Non-U.S. loans averaged $2.4 billion and increased $764.7 million or 46%, from $1.7 billion for the prior-year quarter. Residential real estate loans averaged $6.2 billion and increased $75.4 million, or 1%, from $6.1 billion for the prior-year quarter.
Northern Trust utilizes a diverse mix of funding sources. Average Interest-Bearing Deposits increased $12.0 billion, or 14%, to an average of $99.6 billion in the current quarter from $87.6 billion in the prior-year quarter. Other Average Interest-Related Funds decreased $1.5 billion, or 13%, to an average of $10.3 billion in the current quarter from $11.8 billion in the prior-year quarter. The balances within short-term borrowing classifications vary based on funding requirements and strategies, interest rate levels, changes in the volume of lower-cost deposit sources, and the availability of collateral to secure these borrowings. Average net noninterest-related funds increased $4.1 billion, or 14%, to $34.1 billion in the current quarter from $30.0 billion in the prior-year quarter, primarily resulting from higher levels of Demand and Other Noninterest-Bearing Deposits.
Interest expense for Interest-Bearing Deposits in the current quarter was driven by low and negative interest rates for Non-U.S. Offices Interest-Bearing Deposits and low interest rates on domestic Interest-Bearing Deposits. Average Non-U.S. Offices Interest-Bearing Deposits comprised 71% of total average Interest-Bearing Deposits for the three months ended September 30, 2021.
Provision for Credit Losses
There was a $13.0 million release of credit reserves in the current quarter, as compared to a provision of $0.5 million in the prior-year quarter. The release 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 improvements in projected economic conditions and portfolio credit quality, partially offset by portfolio growth. Decreases in the collective basis reserve were primarily in the commercial and institutional and commercial real estate portfolios.
The provision in the prior-year quarter was primarily due to an increase in the reserve evaluated on a collective basis driven by projected economic conditions at the time, resulting from the ongoing COVID-19 pandemic and related market and economic impacts, with increases in the private client, commercial real estate, and residential real estate portfolios, partially offset by a decrease in the commercial and institutional portfolio. The overall increase in the reserve on a collective basis was partially offset by a decrease in the reserve associated with loans evaluated on an individual basis.
Net recoveries in the current quarter were $1.1 million, reflecting $1.1 million of recoveries and de minimis charge-offs. The prior-year quarter included $0.4 million of net recoveries, reflecting $1.2 million of recoveries and $0.8 million of charge-offs. Nonaccrual assets of $141.2 million increased $42.3 million, or 43%, from $98.9 million at the end of the prior-year quarter.

THIRD QUARTER CONSOLIDATED RESULTS OF OPERATIONS (continued)
Noninterest Expense (continued)
Employee Benefits expense increased compared to the prior-year quarter, primarily due to a pension settlement charge in the current quarter and higher medical costs.
Outside Services expense increased compared to the prior-year quarter, primarily due to higher third-party advisory fees, technical services costs and sub-custodian expenses.
Equipment and Software expense increased compared to the prior-year quarter, primarily due to higher software support and rental costs and higher amortization.
Other Operating Expense decreased compared to the prior-year quarter, primarily due to lower charges associated with account servicing activities and a decline in other miscellaneous expenses, including lower supplemental compensation plan expense. The lower supplemental compensation plan expense resulted in a related decrease in miscellaneous income reported in noninterest income. The account servicing activities in the prior-year quarter included a $43.4 million charge related to a corporate action processing error. Please refer to Note 17 — Other Operating Expense to the consolidated financial statements provided in Item 1. Consolidated Financial Statements (unaudited) for further detail.
Provision for Income Taxes
Income tax expense for the three months ended September 30, 2021 was $122.4 million, representing an effective tax rate of 23.6%, compared to $95.4 million in the prior-year quarter, representing an effective tax rate of 24.5%.
The effective tax rate decreased compared to the prior-year quarter primarily due to an increase in allocated tax credits related to community development projects and a lower net tax impact from international operations.
NINE-MONTH CONSOLIDATED RESULTS OF OPERATIONS
Overview of Financial Results
Net Income per diluted common share increased in the current period to $5.22 from $4.34 in the comparable prior-year period. Net income increased $170.5 million, or 18%, to $1.14 billion in the current period from $968.4 million in the prior-year period. Annualized return on average common equity was 13.7% in the current period and 12.0% in the prior-year period. The annualized return on average assets was 0.98% in the current period compared to 0.96% in the prior-year period.
Revenue for the nine months ended September 30, 2021 increased $218.6 million, or 5%, from $4.58 billion in the prior-year period to $4.80 billion in the current period.
Trust, Investment and Other Servicing Fees increased $281.2 million, or 9%, from $2.97 billion in the prior-year period to $3.25 billion in the current period, primarily driven by favorable markets, new business, and currency translation, partially offset by higher money market mutual fund fee waivers.
Other Noninterest Income increased $24.1 million, or 5% from $501.2 million in the prior-year period to $525.3 million in the current period, primarily driven by higher Other Operating Income and Security Commissions and Trading Income, partially offset by lower Foreign Exchange Trading Income.
Net Interest Income decreased $86.7 million, or 8%, to $1.02 billion in the current period from $1.11 billion in the prior-year period, primarily due to lower average interest rates, partially offset by an increase in average earning assets.
There was a $70.0 million release of credit reserves in the current period, as compared to a provision of $127.5 million in the prior-year period.
Noninterest Expense increased $169.8 million, or 5%, from $3.20 billion in the prior-year period to $3.37 billion in the current period, primarily attributable to higher Compensation, Outside Services, Equipment and Software expense and Employee Benefits, partially offset by lower Other Operating Expense and Occupancy.
The Provision for Income Taxes for the nine months ended September 30, 2021 totaled $361.6 million, representing an effective tax rate of 24.1%. The Provision for Income Taxes for the nine months ended September 30, 2020 totaled $285.8 million, representing an effective tax rate of 22.8%. The effective tax rate increased compared to the prior-year period primarily due to lower tax benefits related to share-based compensation, the deferred tax impact of the enacted increase in the UK statutory tax rate, and a prior-year-period tax benefit from dispositions of leveraged leases.

NINE-MONTH CONSOLIDATED RESULTS OF OPERATIONS (continued)
Trust, Investment and Other Servicing Fees
Beginning in the second quarter of 2020, 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 $206.7 million and $5.7 million of money market mutual fund fees for the nine months ended September 30, 2021 and 2020, respectively. 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 in the table below.

Custody and Fund Administration fees, the largest component of C&IS fees, increased primarily driven by favorable markets, new business, and favorable currency translation. Investment Management fees decreased primarily due to higher money market mutual fund fee waivers, partially offset by favorable markets and new business. Securities Lending fees decreased primarily driven by lower spreads, partially offset by higher volumes.
Wealth Management
Fee income in the regions (Central, East and West) increased primarily due to favorable markets, partially offset by higher money market mutual fund fee waivers. Global Family Office fee income increased primarily due to favorable markets and new business, partially offset by higher money market mutual fund fee waivers.

Security Commissions and Trading Income increased from the prior-year period, primarily due to higher core brokerage revenue, partially offset by lower revenue from interest rate swaps.
Other Operating Income increased from the prior-year period, primarily due to higher banking and credit-related service charges, distributions from investments in community development projects, and higher miscellaneous income, partially offset by higher expenses for existing swap agreements related to Visa Inc. Class B common shares. The higher miscellaneous income was primarily associated with a market value increase in the supplemental compensation plans, which also resulted in a related increase in supplemental compensation plan expense in Other Operating Expense.

For the quarter ended September 30, 2020, net interest income stated on an FTE basis increased $1.2 million, or 1%, fromcompared to the prior-year quarter primarily due to higher revenue from interest rate swaps and core brokerage.
Other Operating Income increased $30.0 million, or 5%, fromcompared to the prior-year period for the nine months ended September 30, 2020. The increase for the three and nine months ended September 30, 2020quarter, primarily reflected higher net interest allocationdriven by distributions from Treasury and Otherinvestments in community development projects and higher depositbanking and loan balances,credit-related service charges, partially offset by lower interest rates. Average earning assets increased $1.6 billion to $29.7 billionmiscellaneous income.

Net Interest Income
Net Interest Income is defined as the total of Interest Income and amortized fees on earning assets, less Interest Expense on deposits and borrowed funds, adjusted for the impact of interest-related hedging activity. Earning assets—including Federal Funds Sold, Securities Purchased under Agreements to Resell, Interest-Bearing Due From Banks, Federal Reserve and Other Central Bank Deposits and Other, Securities, and Loans and Leases—are financed by a large base of interest-bearing funds that include client deposits, short-term borrowings, Senior Notes and Long-Term Debt. Short-term borrowings include Federal Funds Purchased, Securities Sold Under Agreements to Repurchase, and Other Borrowings. Earning assets are also funded by noninterest-related funds, which include demand deposits and stockholders’ equity. Net Interest Income is subject to variations in the level and mix of earning assets and interest-bearing funds and their relative sensitivity to interest rates. In addition, the levels of nonaccruing assets and client compensating deposit balances used to pay for services impact Net Interest Income.
Net interest margin is the difference between what we earn on our assets and what we pay for deposits and other sources of funding. The Wealthdirection and level of interest rates are important factors in our earnings. Net interest margin is calculated by dividing annualized Net Interest Income by average interest-earning assets.
Net Interest Income stated on a fully taxable equivalent (FTE) basis is a non-generally accepted accounting principle (GAAP) financial measure that facilitates the analysis of asset yields. Management provisionbelieves an FTE presentation provides a clearer indication of net interest margins for credit losses was $19.7comparative purposes. When adjusted to an FTE basis, yields on taxable, nontaxable, and partially taxable assets are comparable; however, the adjustment to an FTE basis has no impact on Net Income. A reconciliation of Net Interest Income on a GAAP basis to Net Interest Income on an FTE basis is provided on page 32.

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 $10.7 million and $92.2$7.9 million for the three and nine months ended September 30, 2020, respectively, and a credit provision under the previous “incurred loss” model of $11.8 million and $14.8 million for the three and nine months ended September 30, 2019, respectively.
The provision for the three months ended September 30, 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 32. Net interest margin is calculated by dividing annualized Net Interest Income by average interest-earning assets.
Interest revenue on cash collateral positions is reported above in Interest-Bearing Due from and Deposits with Banks and in Loans and Leases. Interest Expense on cash collateral positions is reported above in Non-U.S. Offices Interest-Bearing Deposits. Related cash collateral received from and deposited with derivative counterparties is recorded net of the associated derivative contract in Other Assets and Other Liabilities, respectively.
Net Interest Income, stated on a FTE basis, increased from the prior-year quarter, primarily due to higher average earning assets, partially offset by a lower net interest margin.Average earning assets increased from the prior-year quarter, primarily due to higher levels of short-term interest-bearing deposits with banks and loans. Funding of the balance sheet reflected higher levels of client deposits.
The net interest margin on an FTE basis decreased from the prior-year quarter, primarily driven by lower average interest rates, partially offset by favorable balance sheet volume and mix shift. Low levels of market interest rates are expected to continue to impact our net interest income.
Federal Reserve and Other Central Bank Deposits and Other averaged $40.5 billion and increased $8.9 billion, or 28%, from $31.6 billion in the prior-year quarter, resulting from significant deposit inflows. The higher level of client deposits were primarily placed with the Federal Reserve and other central banks and in loans. Average Securities were $59.0 billion and increased $923.6 million, or 2%, from $58.1 billion, in the prior-year quarter and include certain community development investments, Federal Home Loan Bank stock, and Federal Reserve stock of $936.9 million, $160.1 million and $70.0 million, respectively, which are recorded in Other Assets on the consolidated balance sheets. Average taxable Securities were $56.4 billion in the current quarter and $52.8 billion in the prior-year quarter. Average nontaxable Securities, which represent securities that are primarily exempt from U.S. federal and state income taxes, were $2.6 billion in the current quarter and

Net Interest Income (continued)
$5.2 billion in the prior-year quarter. Interest-Bearing Due from and Deposits with Banks averaged $5.2 billion in the current quarter and $4.8 billion in the prior-year quarter.
Loans and Leases averaged $38.4 billion and increased $5.3 billion, or 16%, from $33.1 billion in the prior-year quarter, primarily reflecting higher levels of private client, commercial real estate, commercial and institutional, non-U.S., and residential real estate loans. Private client loans averaged $14.5 billion and increased $2.8 billion, or 23%, from $11.7 billion for the prior-year quarter. Commercial real estate loans averaged $4.1 billion and increased $795.2 million, or 24%, from $3.3 billion for the prior-year quarter. Commercial and institutional loans averaged $10.8 billion and increased $766.0 million, or 8%, from $10.0 billion for the prior-year quarter. Non-U.S. loans averaged $2.4 billion and increased $764.7 million or 46%, from $1.7 billion for the prior-year quarter. Residential real estate loans averaged $6.2 billion and increased $75.4 million, or 1%, from $6.1 billion for the prior-year quarter.
Northern Trust utilizes a diverse mix of funding sources. Average Interest-Bearing Deposits increased $12.0 billion, or 14%, to an average of $99.6 billion in the current quarter from $87.6 billion in the prior-year quarter. Other Average Interest-Related Funds decreased $1.5 billion, or 13%, to an average of $10.3 billion in the current quarter from $11.8 billion in the prior-year quarter. The balances within short-term borrowing classifications vary based on funding requirements and strategies, interest rate levels, changes in the volume of lower-cost deposit sources, and the availability of collateral to secure these borrowings. Average net noninterest-related funds increased $4.1 billion, or 14%, to $34.1 billion in the current quarter from $30.0 billion in the prior-year quarter, primarily resulting from higher levels of Demand and Other Noninterest-Bearing Deposits.
Interest expense for Interest-Bearing Deposits in the current quarter was driven by low and negative interest rates for Non-U.S. Offices Interest-Bearing Deposits and low interest rates on domestic Interest-Bearing Deposits. Average Non-U.S. Offices Interest-Bearing Deposits comprised 71% of total average Interest-Bearing Deposits for the three months ended September 30, 2021.
Provision for Credit Losses
There was a $13.0 million release of credit reserves in the current quarter, as compared to a provision of $0.5 million in the prior-year quarter. The release 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 improvements in projected economic conditions and portfolio credit quality, partially offset by portfolio growth. Decreases in the collective basis reserve were primarily in the commercial and institutional and commercial real estate portfolios.
The provision in the prior-year quarter was primarily due to an increase in the reserve evaluated on a collective basis driven by projected economic conditions at the time, resulting from the ongoing COVID-19 pandemic and related market and economic impacts, primarily impactingwith increases in the private client, and commercial real estate, portfolios.and residential real estate portfolios, partially offset by a decrease in the commercial and institutional portfolio. The overall increase in the reserve on a collective basis was partially offset by a decrease in the reserve associated with loans evaluated on an individual basis.
Net recoveries in the current quarter were $1.1 million, reflecting $1.1 million of recoveries and de minimis charge-offs. The prior-year quarter included $0.4 million of net recoveries, reflecting $1.2 million of recoveries and $0.8 million of charge-offs. Nonaccrual assets of $141.2 million increased $42.3 million, or 43%, from $98.9 million at the end of the prior-year quarter.

THIRD QUARTER CONSOLIDATED RESULTS OF OPERATIONS (continued)
Noninterest Expense (continued)
Employee Benefits expense increased compared to the prior-year quarter, primarily due to a pension settlement charge in the current quarter and higher medical costs.
Outside Services expense increased compared to the prior-year quarter, primarily due to higher third-party advisory fees, technical services costs and sub-custodian expenses.
Equipment and Software expense increased compared to the prior-year quarter, primarily due to higher software support and rental costs and higher amortization.
Other Operating Expense decreased compared to the prior-year quarter, primarily due to lower charges associated with account servicing activities and a decline in other miscellaneous expenses, including lower supplemental compensation plan expense. The lower supplemental compensation plan expense resulted in a related decrease in miscellaneous income reported in noninterest income. The account servicing activities in the prior-year quarter included a $43.4 million charge related to a corporate action processing error. Please refer to Note 17 — Other Operating Expense to the consolidated financial statements provided in Item 1. Consolidated Financial Statements (unaudited) for further detail.
Provision for Income Taxes
Income tax expense for the three months ended September 30, 2021 was $122.4 million, representing an effective tax rate of 23.6%, compared to $95.4 million in the prior-year quarter, representing an effective tax rate of 24.5%.
The effective tax rate decreased compared to the prior-year quarter primarily due to an increase in allocated tax credits related to community development projects and a lower net tax impact from international operations.
NINE-MONTH CONSOLIDATED RESULTS OF OPERATIONS
Overview of Financial Results
Net Income per diluted common share increased in the current period to $5.22 from $4.34 in the comparable prior-year period. Net income increased $170.5 million, or 18%, to $1.14 billion in the current period from $968.4 million in the prior-year period. Annualized return on average common equity was 13.7% in the current period and 12.0% in the prior-year period. The annualized return on average assets was 0.98% in the current period compared to 0.96% in the prior-year period.
Revenue for the nine months ended September 30, 2021 increased $218.6 million, or 5%, from $4.58 billion in the prior-year period to $4.80 billion in the current period.
Trust, Investment and Other Servicing Fees increased $281.2 million, or 9%, from $2.97 billion in the prior-year period to $3.25 billion in the current period, primarily driven by favorable markets, new business, and currency translation, partially offset by higher money market mutual fund fee waivers.
Other Noninterest Income increased $24.1 million, or 5% from $501.2 million in the prior-year period to $525.3 million in the current period, primarily driven by higher Other Operating Income and Security Commissions and Trading Income, partially offset by lower Foreign Exchange Trading Income.
Net Interest Income decreased $86.7 million, or 8%, to $1.02 billion in the current period from $1.11 billion in the prior-year period, primarily due to lower average interest rates, partially offset by an increase in average earning assets.
There was a $70.0 million release of credit reserves in the current period, as compared to a provision of $127.5 million in the prior-year period.
Noninterest Expense increased $169.8 million, or 5%, from $3.20 billion in the prior-year period to $3.37 billion in the current period, primarily attributable to higher Compensation, Outside Services, Equipment and Software expense and Employee Benefits, partially offset by lower Other Operating Expense and Occupancy.
The Provision for Income Taxes for the nine months ended September 30, 2021 totaled $361.6 million, representing an effective tax rate of 24.1%. The Provision for Income Taxes for the nine months ended September 30, 2020 totaled $285.8 million, representing an effective tax rate of 22.8%. The effective tax rate increased compared to the prior-year period primarily due to lower tax benefits related to share-based compensation, the deferred tax impact of the enacted increase in the UK statutory tax rate, and a prior-year-period tax benefit from dispositions of leveraged leases.

NINE-MONTH CONSOLIDATED RESULTS OF OPERATIONS (continued)
Trust, Investment and Other Servicing Fees
Beginning in the second quarter of 2020, 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 $206.7 million and $5.7 million of money market mutual fund fees for the nine months ended September 30, 2021 and 2020, respectively. 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 in the table below.

Foreign Exchange Trading Income decreased from the prior-year period, primarily due to lower foreign exchange swap activity in Treasury.
Security Commissions and Trading Income increased from the prior-year period, primarily due to higher core brokerage revenue, partially offset by lower revenue from interest rate swaps.
Other Operating Income increased from the prior-year period, primarily due to higher banking and credit-related service charges, distributions from investments in community development projects, and higher miscellaneous income, partially offset by higher expenses for existing swap agreements related to Visa Inc. Class B common shares. The higher miscellaneous income was primarily associated with a market value increase in the supplemental compensation plans, which also resulted in a related increase in supplemental compensation plan expense in Other Operating Expense. Please refer to Note 16 — Other Operating Income to the consolidated financial statements provided in Item 1. Consolidated Financial Statements (unaudited) for further detail.

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

Notes:    Net Interest Income (FTE Adjusted), a non-GAAP financial measure, includes adjustments to a fully taxable equivalent basis for loans and securities. The adjustments are based on a federal income tax rate of 21.0%, where the rate is adjusted for applicable state income taxes, net of related federal tax benefit. Total taxable equivalent interest adjustments amounted to $25.6 million and $23.7 million for the nine months ended September 30, 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 32. Net interest margin is calculated by dividing annualized net interest income by average interest-earning assets.
Interest revenue on cash collateral positions is reported above within Interest-Bearing Due from and Deposits with Banks and within Loans and Leases. Interest expense on cash collateral positions is reported above within Non-U.S. Offices Interest-Bearing Deposits. Related cash collateral received from and deposited with derivative counterparties is recorded net of the associated derivative contract within Other Assets and Other Liabilities, respectively.
Net Interest Income, stated on an FTE basis, decreased from the prior-year period, primarily due to lower average interest rates, partially offset by an increase in average earning assets. Average earning assets increased primarily due to higher levels of short-term interest-bearing deposits with banks, securities and loans. Funding of the balance sheet reflected higher levels of client deposits. Average non-U.S. offices interest-bearing deposits comprised 71% of total average interest-bearing deposits for the nine months ended September 30, 2021.
The net interest margin on an FTE basis decreased from the prior-year period, primarily due to lower average interest rates. Low levels of market interest rates are expected to continue to impact our net interest income.
Federal Reserve and Other Central Bank Deposits and Other averaged $38.4 billion and increased $11.1 billion, or 41%, from $27.3 billion in the prior-year period, resulting from significant deposit inflows. The higher level of client deposits were primarily placed with the Federal Reserve and other central banks and in the securities portfolio. Average Securities were $60.3 billion and increased $6.0 billion, or 11%, from $54.3 billion in the prior-year period and include certain community development investments, Federal Home Loan Bank stock, and Federal Reserve stock of $919.7 million, $172.1 million and $70.0 million, respectively, which are recorded in Other Assets on the consolidated balance sheets. Average taxable Securities were $57.1 billion in the current period and $48.9 billion in the prior-year period. Average nontaxable Securities, which represent securities that are primarily exempt from U.S. federal and state income taxes, were $3.1 billion in the current period and $5.4 billion in the prior-year period. Interest-Bearing Due from and Deposits with Banks averaged $6.1 billion in the current period and $5.4 billion in the prior-year period.

NINE-MONTH CONSOLIDATED RESULTS OF OPERATIONS (continued)
Net Interest Income (continued)

Loans and leases averaged $36.3 billion and increased $2.7 billion, or 8%, from $33.6 billion in the prior-year period, primarily reflecting higher levels of private client, commercial real estate, non-U.S., and residential real estate loans, partially offset by lower levels of commercial and institutional loans. Private client loans averaged $13.3 billion and increased $1.9 billion, or 16%, from $11.4 billion for the prior-year period. Commercial real estate loans averaged $3.9 billion and increased $681.0 million, or 21%, from $3.2 billion for the prior-year period. Non-U.S. loans averaged $2.5 billion and increased $449.9 million or 22% from $2.0 billion for the prior-year period. Residential real estate loans averaged $6.2 billion and increased $66.2 million, or 1%, from $6.1 billion for the prior-year period. Commercial and institutional loans averaged $10.2 billion and decreased $384.3 million, or 4%, from $10.5 billion for the prior-year period.
Northern Trust utilizes a diverse mix of funding sources. Average Interest-Bearing Deposits increased $13.6 billion, or 16%, to an average of $97.7 billion in the current period from $84.1 billion in the prior-year period. Other Average Interest-Related Funds decreased $2.6 billion, or 20%, to an average of $10.0 billion in the current period from $12.6 billion in the prior-year period. The balances within short-term borrowing classifications vary based on funding requirements and strategies, interest rate levels, changes in the volume of lower-cost deposit sources, and the availability of collateral to secure these borrowings. Average net noninterest-related funds increased $9.5 billion, or 38%, to $34.5 billion in the current period from $25.0 billion in the prior-year period primarily resulting from higher levels of Demand and Other Noninterest-Bearing Deposits.
Provision for Credit Losses
There was a $70.0 million release of credit reserves for the nine months ended September 30, 2021, as compared to a provision of $127.5 million in the prior-year period. The release of credit reserves was primarily due to a decrease in the reserve evaluated on a collective basis, which relates to pooled financial assets sharing similar risk characteristics. The decrease in the collective basis reserve was driven by continued improvements in projected economic conditions and portfolio credit quality, partially offset by portfolio growth.
The provision in the prior-year period was primarily due to an increase in the reserve evaluated on a collective basis driven by downgrades in the portfolio and current and projected economic conditions at the time, both resulting from the ongoing COVID-19 pandemic and related market and economic impacts, primarily impactingwith the largest increases in the commercial and institutional and commercial real estate portfolios. In addition, a $13.7 million increase in the allowance for credit losses, with a corresponding cumulative effect adjustment to decrease retained earnings of $10.1 million, net of income taxes, was recorded on January 1, 2020 upon adoption of Accounting Standards Update (ASU) No. 2016-13, “Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments.”
Net recoveries in the current-year period totaled $5.2 million resulting from $0.4 million of charge-offs and $5.6 million of recoveries, compared to net recoveries of $2.3 million in the prior-year period resulting from $3.0 million of charge-offs and $5.3 million of recoveries.
Commercial real estate, residential real estate, and commercial and institutional loans accounted for 54%, 32%, and 14%, respectively, of total nonaccrual loans and leases at September 30, 2021. Residential real estate, commercial and institutional, and private client portfolios.commercial real estate loans accounted for 65%, 31%, and 4%, respectively, of total nonaccrual loans and leases at September 30, 2020. For additional discussion of the allowance for credit losses, refer to the “Asset Quality” section beginning on page 23.

17

NINE-MONTH CONSOLIDATED RESULTS OF OPERATIONS (continued)
Noninterest Expense (continued)

Employee Benefits expense increased compared to the prior-year period, primarily due to pension settlement charges, higher medical costs, and higher payroll taxes.
Outside Services expense increased compared to the prior-year period, primarily reflecting higher technical services costs, third-party advisory fees, and sub-custodian expenses.
Equipment and Software expense increased compared to the prior-year period, primarily due to higher software support costs and amortization.
Occupancy expense decreased compared to the prior-year period, primarily due to rent accelerations arising from workplace real estate strategies in the prior-year period.
Other Operating Expense decreased compared to the prior-year period, primarily due to lower charges associated with account servicing activities and a decline in other miscellaneous expenses, partially offset by higher supplemental compensation plan expense. The higher supplemental compensation plan expense resulted in a related increase in miscellaneous income reported in noninterest income. The account servicing activities in the prior-year period included a $43.4 million charge related to a corporate action processing error. Please refer to Note 17 — Other Operating Expense to the consolidated financial statements provided in Item 1. Consolidated Financial Statements (unaudited) for further detail.
Provision for Income Taxes
Income tax expense for the nine months ended September 30, 2021 was $361.6 million, representing an effective tax rate of 24.1%, compared to $285.8 million for the nine months ended September 30, 2020, representing an effective tax rate of 22.8%.
The effective tax rate increased compared to the prior-year period primarily due to lower tax benefits related to share-based compensation, the deferred tax impact of the enacted increase in the UK statutory tax rate, and a prior-year-period tax benefit from dispositions of leveraged leases.
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 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.

REPORTING SEGMENTS (continued)
Corporate & Institutional Services
C&IS Net Income
For the quarter ended September 30, 2021, Net Income increased $45.1 million, or 40%, from the prior-year quarter, primarily reflecting higher Trust, Investment and Other Servicing Fees and Net Interest Income, partially offset by a lower release of credit reserves in the current quarter as compared to the prior-year quarter and an increase in the Provision for Income Taxes.
For the nine months ended September 30, 2021, Net Income increased $44.0 million, or 10%, from the prior-year period, primarily reflecting higher Trust, Investment and Other Servicing Fees, a release of credit reserves in the current period as compared to a provision in the prior-year period and higher Other Noninterest Income, partially offset by higher Noninterest Expense, lower Net Interest Income, and an increase in the Provision for Income Taxes.
C&IS Trust, Investment and Other Servicing Fees
For an explanation of C&IS Trust, Investment, and Other Servicing Fees, please see the “Trust, Investment and Other Servicing Fees” section within the Consolidated Results of Operations section of the MD&A.
C&IS Foreign Exchange Trading Income
For the quarter ended September 30, 2020, noninterest expense,2021, Foreign Exchange Trading Income increased $4.8 million, or 8%, from the prior-year quarter, primarily due to higher client volumes. For the nine months ended September 30, 2021, Foreign Exchange Trading Income decreased $6.2 million, or 3%, from the prior-year period, primarily due to lower foreign exchange swap activity.
C&IS Other Noninterest Income
For the quarter ended September 30, 2021, Other Noninterest Income increased $8.9 million, or 16%, from the prior-year quarter, primarily due to higher Security Commissions and Trading Income and Other Operating Income. For the nine months ended September 30, 2021, Other Noninterest Income increased $27.3 million, or 16%, from the prior-year period, primarily due to higher Other Operating Income.
C&IS Net Interest Income
For the quarter ended September 30, 2021, Net Interest Income stated on an FTE basis increased $19.0 million, or 14%, from the prior-year quarter and decreased $43.9 million, or 8%, from the prior-year period for the nine months ended September 30, 2021. The increase for the three months ended September 30, 2021 primarily reflected higher earning asset levels funded by higher deposit balances, partially offset by a slightly lower net interest margin. The decrease for the nine months ended September 30, 2021 primarily reflected decreasing short-term average interest rates, partially offset by higher earning asset levels. Average earning assets increased $10.4 billion to $110.1 billion in the current quarter from $99.7 billion in the prior-year quarter and increased $17.5 billion to $110.0 billion in the nine-month period ended September 30, 2021 from $92.5 billion in the prior-year period. The earning assets and funding sources in C&IS for the three and nine months ended September 30, 2021 consisted primarily of intercompany assets and of loans and non-U.S. custody-related interest-bearing deposits, respectively.
C&IS Provision for Credit Losses
For the quarter ended September 30, 2021, there was a $6.9 million release of credit reserves compared to a $19.2 million release of credit reserves in the prior-year quarter. For the nine months ended September 30, 2021, there was a $29.1 million release of credit reserves compared to a $35.3 million provision for credit losses in the prior-year period.
The release of credit reserves for the three and nine months ended September 30, 2021, was primarily due to a decrease in the reserve evaluated on a collective basis, which relates to pooled financial assets sharing similar risk characteristics. The decrease in the collective basis reserve was driven by continued improvements in projected economic conditions and portfolio credit quality.

Securities Portfolio (continued)
AsHTM debt securities consist of securities that management intends to, and Northern Trust has the ability to, hold until maturity. During the three months ended September 30, 2021, no securities were transferred from AFS to HTM. During the nine months ended September 30, 2021, $6.9 billion of government sponsored agency securities were transferred from AFS to HTM for capital management purposes, all of which were transferred in the second quarter of 2021. Upon transfer of a debt security from the AFS to HTM classification, the amortized cost is reset to fair value. Any net unrealized gain or loss at the date of transfer will remain in AOCI and be amortized into net interest income over the remaining life of the securities using the effective interest method. The amortization of amounts retained in AOCI will offset the effect on interest income of the amortization of the premium or discount resulting from transferring the securities at fair value. During the three months ended September 30, 2020, 21%no securities were transferred from AFS to HTM. During the nine months ended September 30, 2020, $301.5 million of securities reflected in U.S government were transferred from AFS to HTM, all of which were transferred in the corporate debt securities available for sale portfolio was backed by guarantees provided by U.S. and non-U.S. government entities.second quarter of 2020.
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 costlow-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.
For additional information relating to the securities sold under agreements to repurchase, refer to Note 5 — Securities Sold Under Agreements to Repurchase to the consolidated financial statements provided in Item 1. Consolidated Financial Statements (unaudited).
Nonaccrual Loans and Leases and Other Real Estate Owned
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 reflect 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, renegotiationsrenegotiation and renewals.

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 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 credit policies do not allow for the origination of loan types generally considered to be high risk in nature, such as option adjustable rate mortgage loans, subprime loans, loans with initial “teaser” rates and loans with excessively high loan-to-value ratios. Residential real estate loans consist of first lien mortgages and equity credit lines, which generally require a loan-to-collateral value of no more than 65% to 80% at inception. Appraisals of supporting collateral for residential real estate loans are obtained at loan origination and upon refinancing or default or when otherwise considered warranted. Residential real estate collateral appraisals are performed and reviewed by independent third parties.
The commercial real estate portfolio consists of commercial mortgages and construction, acquisition and development loans extended primarily to experienced investors well known to Northern Trust. Underwriting standards generally reflect conservative loan-to-value ratios and debt service coverage requirements. Recourse to owners through guarantees also is commonly required.
For additional information relating to the loans and leases portfolio, refer to Note 6 — Loans and Leases to the consolidated financial statements provided in Item 1. Consolidated Financial Statements (unaudited).
Allowance for Credit Losses
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 ASU No. 2016-13, “Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments” (ASU 2016-13) on January 1, 2020, which significantly changed 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 by $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.

Operating Activities
Net cash used in operating activities of $685.9 million for the nine months ended September 30, 2021 was primarily attributable to higher net collateral deposited with derivative counterparties, partially offset by period earnings and the impact of higher non-cash charges such as depreciation and amortization.
Net cash provided by operating activities of $420.5 million for the nine months ended September 30, 2020 was primarily attributable to period earnings and the impact of higher non-cash charges such as depreciation and amortization of computer software and the provision for credit losses, partially offset by higher net collateral deposited with derivative counterparties and net changes in other operating activities.
For the nine months ended September 30, 2019, net cash provided by operating activities of $955.6 million was primarily attributable to period earnings and the impact of non-cash charges such as amortization of computer software, partially offset by an increase in accounts receivable and net changes in other operating activities.
Investing Activities
Net cash provided by investing activities of $188.4 million for the nine months ended September 30, 2021 was primarily attributable to decreased levels of Federal Reserve and other central bank deposits, net proceeds from HTM debt securities, lower levels of interest-bearing deposits with banks, net changes in other investing activities, and lower levels of securities purchased under agreements to resell, partially offset by higher levels of loans and leases, net purchases of AFS debt securities and higher client security settlement receivables.
Net cash used in investing activities of $13.1 billion for the nine months ended September 30, 2020 was primarily attributable to increased levels of Federal Reserve and other central bank deposits as well as net purchases of debt securities held to maturity and available for sale, partially offset by lower levels of interest-bearing deposits with banks.
ForFinancing Activities
Net cash provided by financing activities of $430.0 million for the nine months ended September 30, 2019, net cash provided by investing activities of $9.0 billion 2021 was primarily attributable to decreasedincreased levels of Federal Reserveshort-term borrowings and securities sold under agreements to repurchase, partially offset by repayments of senior notes, dividends paid on common stock, a decrease in total deposits, the repurchase of common stock pursuant to the Corporation’s share repurchase program, and a decrease in federal funds purchased. The decrease in total deposits was primarily attributable to lower levels of non-U.S offices noninterest-bearing and interest-bearing client deposits, partially offset by an increase in domestic noninterest-bearing deposits and savings, money market, and other central bank deposits, and net proceeds associated with debt securities held to maturity.

The 2020 stress capital buffer became effective October 1, 2020, and resultsresulted in a common equity tieran effective Common Equity Tier 1 capital ratio minimum requirement of 7.0%. inclusive of this buffer. The results of the 2021 stress test, published by the Federal Reserve on June 24, 2021, resulted in Northern Trust’s stress capital buffer and effective Common Equity Tier 1 capital ratio minimum requirement remaining in effect for the 2021 Capital Plan cycle, beginning on October 1, 2021.

(1) In November 2019, the Federal Reserve and other U.S. federal banking agencies adopted a final rule that established a deduction for central bank deposits from the total leverage exposures of custodial banking organizations, including Northern Trust Corporation and The Northern Trust Company, equal to the lesser of (i) the total amount of funds the custodial banking organization and its consolidated subsidiaries have on deposit at qualifying central banks and (ii) the total amount of client funds on deposit at the custodial banking organization that are linked to fiduciary or custodial and safekeeping accounts. The rule became effective on April 1, 2020.
Further, on April 1,March 23, 2020, the Federal Reserve issued an interim finala temporary rule that requiresrequired bank holding companies, including Northern Trust Corporation, to deduct on a temporary basis,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 will remain in effect through the first quarter ofexpired on April 1, 2021.
On May 15, 2020, the U.S. federal banking agencies released an interim finalissued a temporary rule that permitspermitted, but did not require, insured depository institutions of bank holding companies also to temporarily 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.
The supplementary leverage ratios at September 30, 20202021, June 30, 2021 and JuneSeptember 30, 2020 for the Northern Trust Corporation and The Northern Trust Company reflect the impact of these final rules.

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 Statements 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 U.S. Securities and Exchange Commission (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.

For Northern Trust, accounting estimates that are viewed as critical are those relating to the allowance 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. 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. For a description of Northern Trust’s estimate related to the allowance for credit losses, refer to the Critical Accounting Estimates section in the Form 10-Q for the quarter ended March 31, 2020. For more information on the adoption of ASU 2016-13, please refer to Note 2 — Recent Accounting Pronouncements and Note 7 — Allowance for Credit Losses to the consolidated financial statements provided in Item 1. Consolidated Financial Statements (unaudited).
RECENT ACCOUNTING PRONOUNCEMENTS AND DEVELOPMENTS
In January 2020, the Financial Accounting Standards Board (FASB)There are no accounting pronouncements and developments issued 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 clarifiesSeptember 30, 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 condition or results of operations.

In August 2020, the FASB issued ASU No. 2020-06, “Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity” (ASU 2020-06). ASU 2020-06 simplifies the convertible instrument accounting framework through the elimination of the beneficial conversion and cash conversion accounting models used to account for convertible debt and convertible preferred stock. ASU 2020-06 also amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of specific settlement provisions in Accounting Standards Codification 815—Derivatives and Hedging. In addition, ASU 2020-06 modifies how particular convertible instruments and certain contracts that may be settled in cash or shares impact the diluted earnings per share computation. ASU 2020-06 is effective for interim and annual periods beginning after December 15, 2021, although early adoption is permitted. ASU 2020-06 is not expected to have a significant impact on Northern Trust’s consolidated financial conditionbalance sheets 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
29

MARKET RISK MANAGEMENT (continued)

interest rate changes on NII. MVE sensitivity provides management with a long-term view of interest rate changes on MVE based on the period-end balance sheet.
As part of its risk management activities, Northern Trust also measures daily the risk of loss associated with all non-U.S. currency positions using a Value-at-Risk (VaR) model and applying the historical simulation methodology. The following
32

MARKET RISK MANAGEMENT (continued)

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.

100 Basis Points$192308 
200 Basis Points337534 
Decrease in Interest Rates Below Market Implied Forward Rates
100 Basis Points$7836 
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
30

MARKET RISK MANAGEMENT (continued)

assumptions that apply to NII sensitivity also apply to MVE sensitivity simulations, with the following separate key assumptions incorporated into the MVE simulation:

33

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 — judgment—some balances are assumed to be core and have longer lives while other balances are assumed to be temporary and have comparatively shorter lives;
the present values of most noninterest-related balances (such as receivables, equipment, and payables) are the same as their book values; and
Monte Carlo simulation is used to generate forward interest rate paths.
The following table shows the estimated impact on MVE of 100 and 200 basis point shocks up and a 100 basis point shock down from current market implied forward rates.

The MVE simulations do not incorporate certain management actions that may be used to mitigate adverse effects of actual interest rate movements. For that reason and others, the estimated impacts do not reflect the likely actual results but serve as estimates of interest rate risk. MVE sensitivity is not comparable to actual results disclosed elsewhere or directly predictive of future values of other measures provided.
Foreign Currency Value-At-Risk (VaR) — Northern Trust measures daily the risk of loss associated with all non-U.S. currency positions using a VaR model and applying the historical simulation methodology. This statistical model provides 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 and interest rates were to occur over a small number of days. The model incorporates foreign currency and interest rate volatilities and correlations in price movements among the currencies. VaR is computed for each trading desk and for the global portfolio.
Northern Trust monitors several variations of the global foreign exchange (GFX) VaR measures to meet specific regulatory and internal management needs. Variations include different methodologies (historical simulation, Monte Carlo simulation and Taylor approximation), horizons of one day and ten days, confidence levels of 95% and 99%, subcomponent VaRs using only foreign exchange (FX) drivers and only interest rate (IR) drivers, and look-back periods of one year, two years, and four years. Those alternative measures provide management an array of corroborating metrics and alternative perspectives on Northern Trust’s market risks.
During the three and nine months ended September 30, 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.

ASU 2016-13 significantly changed 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 purchased credit-impaired debt securities and loans.

Upon adoption of ASU 2016-13, Northern Trust recorded a $13.7 million increase in(2) the allowance for credit losses with a corresponding cumulative effect adjustment to decrease retained earnings by $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 fromcertain forward contracts and purchased options to acquire equity securities. ASU 2020-01 clarifies that an entity applying the goodwill impairment test is eliminated. As a result,measurement alternative under Topic 321 that must transition to the goodwill impairment test is performed by comparingequity 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 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.Topic 321 before settlement or exercise.

On April 1, 2020, Northern Trust adopted ASU No. 2020-04,2021-01, “Reference Rate Reform (Topic 848): FacilitationScope” (ASU 2021-01). ASU 2021-01 clarifies the scope of the Effects of Reference Rate Reform on Financial Reporting” (ASU 2020-04). The global transition toward alternative referenceTopic 848 to explicitly include those derivative instruments affected by changes in interest 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 ofused for margining, discounting, or 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 temporaryprice alignment as eligible for certain 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.

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 for which an entity has elected certain optional expedients and which are retained through the end of the hedging relationship.Topic 848.

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 nine months ended September 30, 20202021 or the twelve monthsyear ended December 31, 2019.2020.
40

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 (AFS) investments in U.S. Treasury securities.
Level 2 Observable inputs other than Level 1 prices, such as quoted active market prices for similar assets or liabilities, quoted prices for identical or similar assets in inactive markets, and model-derived valuations in which all significant inputs are observable in active markets.
Northern Trust’s Level 2 assets include available for saleAFS 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 September 30, 2020,2021, Northern Trust’s available for saleAFS debt securities portfolio included 2,0862,501 Level 2 debt securities with an aggregate market value of $38.4$35.5 billion. All 2,086Substantially all 2,501 debt securities were valued by external pricing vendors. As of December 31, 2019,2020, Northern Trust’s available for saleAFS 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 $0.6$0.2 million and $0.3$0.5 million as of September 30, 20202021 and December 31, 2019,2020, respectively, were all valued using external pricing vendors.

Notes to Consolidated Financial Statements (unaudited) (continued)
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 1921 — 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 September 30, 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.

Notes to Consolidated Financial Statements (unaudited) (continued)
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 September 30, 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 average based on fair values of 15.2%15.6% and 15.3%16.8% as of September 30, 20202021 and December 31, 2019,2020, respectively. Other loan collateral, which typically consists of accounts receivable, inventory and equipment, is valued using a market approach adjusted for asset-specific characteristics and in limited instances third-party valuations are used. OREO assets are carried at the lower of cost or fair value less estimated costs to sell, with fair value typically based on third-party appraisals.
Collateral-based nonaccrual loans that have been adjusted to fair value totaled $21.2$14.7 million and $8.0$24.6 million at September 30, 20202021 and December 31, 2019,2020, respectively.
The following table presents the fair values of Northern Trust’s Level 3 assets that were measured at fair value on a nonrecurring basis as of September 30, 20202021 and December 31, 2019,2020, as well as the valuation technique, significant unobservable inputs and quantitative information used to develop the significant unobservable inputs for such assets as of such dates.

As of September 30, 2020,2021, Northern Trust did not intend to sell any AFS 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.
DebtAFS 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 0no provision for credit losses for corporate debt AFS securities available for sale for the three and nine months ended September 30, 2021 and 2020, and 0respectively. There was no allowance for credit losses for corporate debt AFS securities available for sale as of September 30, 2020.2021 and December 31, 2020, respectively. The process for identifying credit losses for corporate debt available for saleAFS securities is based on the best estimate of cash flows to be collected from the security, discounted using the security’s effective interest rate. If the present value of the expected cash flows is found to be less than the current amortized cost of the security, an allowance for credit losses is generally recorded equal to the difference between the two amounts, limited to the amount the amortized cost basis exceeds the fair value of the security. For additional information, please refer to Note 7 — Allowance for Credit Losses.
For a description of Northern Trust’s accounting policies applied prior to the adoption of ASU 2016-13, refer to Note 1 — Summary of Significant Accounting Policies and Note 4 — Securities included under Item 8.

The amortization of amounts retained in AOCI will offset the effect on interest income of the amortization of the premium or discount resulting from transferring the securities at fair value. During the three months ended September 30, 2020, no securities were transferred from AFS to HTM. During the nine months ended September 30, 2020, $301.5 million of securities reflected in U.S.U.S government were transferred from available for saleAFS to held to maturity,HTM, all of which were transferred in the second quarter of 2020. During the three and nine months ended September 30, 2019, $160.8 million securities reflected in covered bonds were transferred from available for sale to held to maturity.

Note 5 – Securities Sold Under Agreements to Repurchase
Securities sold under agreements to repurchase are accounted for as collateralized financings and recorded at the amounts at which the securities were sold plus accrued interest. To minimize any potential credit risk associated with these transactions, the fair value of the securities sold is monitored, limits are set on exposure with counterparties, and the financial condition of counterparties is regularly assessed. Securities sold under agreements to repurchase are held by the counterparty until the repurchase.

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 that thea borrower has used theuses 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. 109 PPP loan forgiveness applications were in process as of September 30, 2020, though 0 PPP loans of the total $215.3 million PPP loans had been submitted for forgiveness approval to the SBA as of such date. When Northern Trust submits the forgiveness applications to the SBA, the SBA will havehas at least 90 days to respond to Northern Trust as to the approval or denial of such application. 1,245 applications went through the PPP loan forgiveness process and resulted in $214.0 million of loan principal and interest being forgiven as of September 30, 2021.

As of September 30, 2020,2021, Northern Trust had net of repayments, $215.3314 outstanding loans totaling $79.6 million or 1,127 loans, under the PPP in theits commercial and institutional portfolio with an average loan balance of $0.2$0.3 million. As of September 30, 2020, forFor its origination efforts, Northern Trust had received approximately $2.6$2.7 million in SBA fees, net of service charges.charges as of September 30, 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 September 30, 2021 and December 31, 2020 are provided in the following table, segregated by borrower ratings into “1 to 3,” “4 to 5” and “6 to 9” (watch list and nonaccrual status) categories by year of origination at amortized cost basis. Loans that are held for investment are reported at the principal amount outstanding, net of unearned income.

Loans and leases in the “1 to 3” category are expected to exhibit minimal to modest probabilities of default and are characterized by borrowers having the strongest financial qualities, including above average financial flexibility, cash flows and capital levels. Borrowers assigned these ratings are anticipated to experience very little to moderate financial pressure in

adverse down-cycle scenarios. As a result of these characteristics, borrowers within this category exhibit a minimal to modest likelihood of loss.

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

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

For credit quality indicator information that was required under the former provisions of ASC Topic 310, please refer to Note 6 — Loans and Leases included under Item 8. Financial Statements and Supplementary Data 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 $1.5 million and $3.2 million for the three and nine months ended September 30, 2021, and $1.1 million and $3.5 million for the three and nine months ended September 30, 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 September 30, 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.
60

Notes to Consolidated Financial Statements (unaudited) (continued)
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
57

Notes to Consolidated Financial Statements (unaudited) (continued)
(TDR). All TDRs are reported as TDRs starting in the calendar year of their restructuring. In subsequent years, a TDR may cease being 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 $67.5$73.5 million and $54.9$38.9 million of nonaccrual TDRs, and $33.0$23.3 million and $27.7$29.3 million of accrual TDRs as of September 30, 20202021 and December 31, 2019,2020, respectively.
There were $11.0$0.2 million and $8.2$10.4 million of aggregate undrawn loan commitments and standby letters of credit at September 30, 20202021 and December 31, 2019,2020, respectively, issued to borrowers with TDR modifications of loans.

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

Various banking regulators, including the Board of Governors of the Federal Reserve System, the Federal Deposit Insurance Corporation, the National Credit Union Administration, the Office of the Comptroller of the Currency, and the Consumer Financial Protection Bureau, have issued guidance in the April 7, 2020 Interagency Statement on Loan Modifications and

Notes to Consolidated Financial Statements (unaudited) (continued)
Reporting for Financial Institutions Working with Customers Affected by the Coronavirus (revised) (revised) on loan modification treatment (Interagency Guidance) pursuant to which financial institutions can apply ASC 310-40 Receivables – Troubled Debt Restructurings by Creditors. In accordance with the Interagency Guidance, a loan modification is not considered a TDR if the modification is related to COVID-19; the borrower had been current (not more than 29 days past due) when the modification program was implemented; and the modification includes payment deferrals for not more than 6 months.

Under section 4013 of the CARES Act, relief provided to lenders exempting certain loan modifications which would otherwise be classified as TDRs from such classification applies for loans that were current and existingnot 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) December 31, 2020January 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 has elected to apply both the CARES Act and the Interagency Guidance, as applicable, in providing borrowers with loan modification relief in response to the COVID-19 pandemic. All other types of modifications which do not meet the CARES Act or Interagency Guidance requirements continue to be governed by existing regulations and accounting policies.

The following tables provide, by segment and class, the number of total COVID-19-related loan modifications including the loan volume and deferred principal and interest balances as of September 30, 2020,2021, for which Northern Trust applied an exemption from TDR classification that are in active deferral (loans currently in the deferral period) or completed deferral (loans that returned to their regular payment schedule).

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

Collateral Dependent Financial Assets. A financial asset is collateral-dependent whenDuring the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the sale or operationquarter ended September 30, 2021, 33 loans with an aggregate principal amount 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$80.9 million that had been granted payment deferrals were paid off. As of September 30, 2020 was immaterial to Northern Trust’s financial statements.2021, less than 10% of loans that had been granted payment deferrals were either past due or in nonaccrual status.
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.

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 changed 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. 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. 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).

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 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 DesignDevelopment 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 and nine months ended September 30, 20202021 and 2019.

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

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

There was a $0.5$13.0 million Provision for Credit Lossesrelease of credit reserves in the current quarter, as calculated under the Current Expected Credit Losses (CECL) methodology, as compared to a $7.0$0.5 million credit provision in the prior-year quarter calculated under the previous “incurred loss” model.quarter. There were net recoveries of $0.4$1.1 million during the three months ended September 30, 2020,2021, as compared to net recoveries of $0.6$0.4 million for the three months ended September 30, 2019.2020. The provisionrelease of credit reserves in the current quarter mostly related to undrawn loan commitments and standby letters of credit and loans and leases. For further detail, please see the Allowance for the Loan and Lease Portfolio section below.
There was primarily duea $70.0 million release of credit reserves for the nine months ended September 30, 2021, as compared to an increase ina $127.5 million provision for the reserve evaluated on a collective basis, which relatesnine months ended September 30, 2020. There were net recoveries of $5.2 million for the nine months ended September 30, 2021, as compared to pooled financial assets sharing similar risk characteristics.net recoveries of $2.3 million for the nine months ended September 30, 2020. The increase in the collective basis reserve was driven by projected economic conditions resulting from the ongoing COVID-19 pandemic and related market and economic impacts, with increases in the private client, commercial real estate, and residential real estate portfolios, partially offset by a decrease in the commercial and institutional portfolio. The overall increase in the reserve on a collective basis was partially offset by a decrease in the reserve associated with loans evaluated on an individual basis.

There was a $127.5 million Provision for Credit Lossesrelease of credit reserves for the nine months ended September 30, 2020 as calculated under2021 mostly related to loans and leases. For further detail, please see the CECL methodology, as compared to a $13.5 million credit provision in the prior-year period calculated under the previous “incurred loss” model. There were net recoveries of $2.3 million during the nine months ended September 30, 2020, as compared to net recoveries of $3.0 millionAllowance for the nine months ended September 30, 2019. The provision in the current period was primarily due to an increase in the reserve evaluated on a collective basis driven by downgrades in the portfolioLoan and current and projected economic conditions, both resulting from the ongoing COVID-19 pandemic and related market and economic impacts, with the largest increases in the commercial and institutional and commercial real estate portfolios.

Lease Portfolio section below.
Forecasting and Reversion. Estimating expected lifetime credit losses requires the consideration of the effect of future economic conditions. Northern Trust employs multiple scenarios over a reasonable and supportable period (currently two years) to project future conditions. Management determines the probability weights assigned to each scenario at each quarter-end. Key variables determined to be relevant for projecting credit losses on the portfolios in scope include macroeconomic factors, such as corporate profits, unemployment, and real estate price indices, as well as financial market factors such as equity prices, volatility, and credit spreads. For periods beyond the reasonable and supportable period, Northern Trust reverts to its own historical loss experiences on a straight-line basis over four quarters.

For the current quarter, the primary forecast, consistent with Northern Trust’s economic outlook publications, assumes continued economic recovery from the challenges of COVID-19, with steady 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.

by projected economic conditions resulting from the ongoing COVID-19 pandemic with decreases in the non-U.S commercial and commercial and institutional portfolios, partially offset by increases in the private client portfolio.
The increase to the allowance for both loans and leases and undrawn loan commitments and standby letters of credit for the nine months ended September 30, 2020 was primarily due to an increase in the reserve evaluated on a collective basis driven by downgrades in the portfolio and current and projected economic conditions, both resulting from the ongoing COVID-19 pandemic and related market and economic impacts, with the largest increases in the commercial and institutional and commercial real estate 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 is primarily based on internally developed loss data specific to the Northern Trust financial asset portfolio from a historical observation period that includes both expansionary and recessionary periods. The estimation methodology and the related qualitative adjustment framework segregate the loan and lease portfolio into homogenous segments based on similar risk characteristics or risk monitoring methods.

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

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

The following table provides information regarding the recorded investments in loans and leases and the allowance for credit losses for loans and leases and undrawn loan commitments and standby letters of credit by segment as of September 30, 20202021 and December 31, 2019.2020.

HTM 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 increase to the allowance attributable to debt securities held to maturity for the three and nine months ended September 30, 2020 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.
DebtHTM 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.
DebtHTM 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 HTM 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.

Notes to Consolidated Financial Statements (unaudited) (continued)
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 MaturityHTM debt securities portfolio. It consists of a combination of externally and internally developed loss data, adjusted for the appropriate contractual term. Northern Trust’s portfolio of Other Financial Assets is composed mostly of institutions within the “1 to 3” internal borrower rating category and is expected to exhibit minimal to modest likelihood of loss. The allowance for credit losses related to Other Financial Assets was $0.7$1.0 million and $0.8 million as of September 30, 2020.2021 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.
The following table provides the amount of accrued interest excluded from the amortized cost basis of the following portfolios.

Note 10 – Reporting Segments
Northern Trust is organized around its 2 client-focused reporting segments: Corporate & 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
67

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

NotesEffective January 1, 2021, Northern Trust implemented enhancements to Consolidated Financial Statements (unaudited) (continued)

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.

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

For the three months ended September 30, 2021, Other Operating Income increased compared to the prior-year quarter, primarily driven by distributions from investments in community development projects and higher banking and credit-related service charges, partially offset by lower miscellaneous income. The lower miscellaneous income was primarily associated with a market value decrease in the supplemental compensation plans, which also resulted in a related decrease in supplemental compensation plan expense reported in Other Operating Expense.
For the nine months ended September 30, 2021, Other Operating Income increased compared to the prior-year period primarily due to higher banking and credit-related service charges, distributions from investments in community development projects, and higher miscellaneous income, partially offset by higher expenses for existing swap agreements related to Visa Inc.

Northern Trust’s U.S. Qualified Plan provides participants the option to select lump-sum benefit payments upon retirement and termination of service. In the second quarter of 2021 it became probable that total lump-sum payments in 2021 would exceed the settlement threshold of the sum of annual service and interest cost. Northern Trust expectsrecognized settlement charges related to changeits U.S. Qualified Plan in the plan designsecond and third quarter of its post-retirement health care plan2021 and will record a settlement charge in the fourth quarter of 2021.

The quarterly settlement charge represents the pro rata amount of the net loss in AOCI that is charged to income based on the proportion of the Projected Benefit Obligation settled to the total Projected Benefit Obligation and amounted to $6.9 million and $24.5 million for the three and nine months ended September 30, 2021, respectively.

The application of settlement accounting required an interim remeasurement of the U.S. Qualified Plan as of January 1, 2021, which results inquarter-end.

Note 1820 – 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 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 $30.1 million and $42.6 million as of September 30, 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

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.
77

Notes to Consolidated Financial Statements (unaudited) (continued)

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 September 30, 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 $761.3$949.4 million and $749.3$919.6 million, respectively, of which $715.5$906.7 million and $700.3$874.0 million are VIEs as of September 30, 20202021 and December 31, 2019,2020, respectively. As of September 30, 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 $300.0$313.5 million and $376.2$351.6 million, respectively, of which $283.5$297.7 million and $354.3$335.9 million related to undrawn commitments on VIEs as of September 30, 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 0no 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 $20.7$22.0 million and $16.4$20.7 million for the three months ended September 30, 20202021 and 2019,2020, respectively, and $59.4$68.1 million and $49.2$59.4 million for the nine months ended September 30, 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 $76.7 million of money market mutual fund fees for the three months ended September 30, 2021 and $206.7 million for the nine months ended September 30, 2021 related to the low-interest-rate environment and certain competitive factors. Northern Trust voluntarily waived $5.4 million and $5.7 million of money market mutual fund fees for the three and nine months ended September 30, 2020, respectively. Northern Trust did not waive any money market mutual fund fees for the three and nine months ended September 30, 2019.2020. Northern Trust does 0tnot 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 September 30, 2021, and December 31, 2020, Northern Trust had $1.7 million of investments valued using net asset value per share and included in Other Assets and had $73.3 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 1921 – 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 maximum potential credit exposure should the instrument be fully drawn upon and the client default. To control the credit risk associated with entering into commitments and issuing letters of credit, Northern Trust subjects such activities to the same credit quality and monitoring controls as its lending activities. Northern Trust does not believe the total contractual amount of these instruments to be representative of its future credit exposure or funding requirements.

Undrawn Commitments generally have fixed expiration dates or other termination clauses. Since a significant portion of the commitments are expected to expire without being drawn upon, the total commitment amount does not necessarily represent future loans or liquidity requirements. Legally binding commitments to extend credit totaled $26.4 billion and $24.4 billion as
Standby Letters of September 30, 2020 and December 31, 2019, respectively.
Standby letters of creditCredit obligate Northern Trust to meet certain financial obligations of its clients, if, under the contractual terms of the agreement, the clients are unable to do so. These instruments are primarily issued to support public and private financial commitments, including commercial paper, bond financing, initial margin requirements on futures exchanges and similar transactions. Northern Trust is obligated to meet the entire financial obligation of these agreements and in certain cases is able to recover the amounts paid through recourse against collateral received or other participants. Standby letters of credit outstanding and financial guarantees were $2.1 billion and $2.4 billion as of September 30, 2020 and December 31, 2019, respectively.
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.

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 September 30, 20202021 and December 31, 20192020 subject to indemnification was $148.3$180.6 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 0no liability was recorded as of September 30, 20202021 or December 31, 2019,2020, related to these indemnifications.
Sponsored Member Program.Effective during the third quarter of 2021, Northern Trust became an approved Government Securities Division (GSD) netting and sponsoring member in the FICC sponsored member program, through which Northern Trust submits eligible repurchase and reverse repurchase transactions in U.S. Government securities between Northern Trust and its sponsored member clients for novation and clearing. Northern Trust may sponsor clients to clear their eligible repurchase transactions with the FICC. As a sponsoring member, Northern Trust guarantees to the FICC the prompt and full payment and performance of its sponsored member clients’ respective obligations under the FICC GSD’s rules. To mitigate Northern Trust’s credit exposure under this guarantee, Northern Trust obtains a security interest in its sponsored member clients’ collateral. See Note 23 - Offsetting of Assets and Liabilities for additional information on Northern Trust’s repurchase and reverse repurchase agreements.
Unsettled Repurchase and Reverse Repurchase Agreements.Northern Trust enters into repurchase agreements and reverse repurchase agreements which may settle at a future date. In repurchase agreements, Northern Trust receives cash from and provides securities as collateral to a counterparty. In reverse repurchase agreements, Northern Trust advances cash to and receives securities as collateral from a counterparty. These transactions are recorded on the consolidated balance sheets on the settlement date. As of September 30, 2021, there were no unsettled repurchase agreements and $99.5 million of unsettled reverse repurchase agreements. As of December 31, 2020, there were no unsettled repurchase or reverse repurchase agreements.
Clearing and Settlement Organizations.The Bank is a participating member of various cash, securities and foreign exchange clearing and settlement organizations. It participates in these organizations on behalf of its clients and on its own behalf as a result of its own activities. A wide variety of cash and securities transactions are settled through these organizations, including those involving obligations of states and political subdivisions, asset-backed securities, commercial paper, dollar placements, and securities issued by the Government National Mortgage Association.
Certain of these industry clearing and settlement exchanges require their members to guarantee their obligations and liabilities and/or to provide liquidity support in the event other members do not honor their obligations as stipulated in each clearing organization’s membership agreement. Exposure related to these agreements varies, primarily as a result of fluctuations in the volume of transactions cleared through the organizations. At September 30, 2021 and December 31, 2020, Northern Trust has not recorded any material liabilities under these arrangements as Northern Trust believes the likelihood that a clearing or settlement exchange (of which Northern Trust is a member) would become insolvent is remote. Controls related to these clearing transactions are closely monitored by management to protect the assets of Northern Trust and its clients.
Legal Proceedings. In the normal course of business, the Corporation and its subsidiaries are routinely defendants in or parties to pending and threatened legal actions, and are subject to regulatory examinations, information-gathering requests, investigations, and proceedings, both formal and informal. In certain legal actions, claims for substantial monetary damages are
79

Notes to Consolidated Financial Statements (unaudited) (continued)

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

Under GAAP, (i) an event is “probable” if the “future event or events are likely to occur”; (ii) an event is “reasonably possible” if “the chance of the future event or events occurring is more than remote but less than likely”; and (iii) an event is “remote” if “the chance of the future event or events occurring is slight.”
The outcome of litigation and regulatory matters is inherently difficult to predict and/or the range of loss often cannot be reasonably estimated, particularly for matters that (i) will be decided by a jury, (ii) are in early stages, (iii) involve uncertainty as to the likelihood of a class being certified or the ultimate size of the class, (iv) are subject to appeals or motions, (v) involve significant factual issues to be resolved, including with respect to the amount of damages, (vi) do not specify the amount of damages sought or (vii) seek very large damages based on novel and complex damage and liability legal theories. Accordingly, the Corporation cannot reasonably estimate the eventual outcome of these pending matters, the timing of their ultimate resolution or what the eventual loss, fines or penalties, if any, related to each pending matter will be.
In accordance with applicable accounting guidance, the Corporation records accruals for litigation and regulatory matters when those matters present loss contingencies that are both probable and reasonably estimable. When loss contingencies are not both probable and reasonably estimable, the Corporation does not record accruals. NaNNo 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 September 30, 2020,2021, the Corporation has estimated the range of reasonably possible loss for these matters to be from 0zero to approximately $15$20 million in the aggregate. The Corporation’s estimate with respect to the aggregate range of reasonably possible loss is based upon currently available information and is subject to significant judgment and a variety of assumptions and known and unknown uncertainties. The matters underlying the estimated range will change from time to time, and actual results may vary significantly from the current estimate.
In certain other pending matters, there may be a range of reasonably possible loss (including reasonably possible loss in excess of amounts accrued) that cannot be reasonably estimated for the reasons described above. Such matters are not included in the estimated range of reasonably possible loss discussed above.
In 2015, Northern Trust Fiduciary Services (Guernsey) Limited (NTFS), an indirect subsidiary of the Corporation, was charged by a French investigating magistrate judge with complicity in estate tax fraud in connection with the administration of 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
82

Notes to Consolidated Financial Statements (unaudited) (continued)

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 million and $99.9 million net gain on the sale of 1.1 million and 1.0 million of its Visa Class B common shares, respectively. These sales do not affect Northern Trust’s risk related to the impact of the covered litigation on the rate at which such shares will ultimately convert into Visa Class A common shares. Northern Trust continued to hold approximately 4.1 million Visa Class B common shares, which are recorded at their original cost basis of 0,zero, as of September 30, 20202021 and December 31, 2019.2020.
Note 2022 – 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 saleAFS debt securities and long-term subordinated debt and senior notes. Northern Trust applied the

82

Notes to Consolidated Financial Statements (unaudited) (continued)

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 saleAFS 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 0no material gains or losses reclassified into earnings during the three- and nine- month periods ended September 30, 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 gains of $0.9 million and net losses of $16.3$2.2 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 $0.3 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.transactions. As of September 30, 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.

Net Investment Hedges. Certain foreign exchange contracts are designated as net investment hedges to minimize Northern Trust’s exposure to variability in the foreign currency translation of net investments in non-U.S. branches and subsidiaries. Net investment hedge gains of $86.7 million and losses of $117.4 million and gains of $107.6 million were recognized in AOCI related to foreign exchange contracts for the three months ended September 30, 20202021 and 2019,2020, respectively. Net investment hedge gains of $157.3 million and losses of $29.8 million and gains of $144.1 million were recognized in AOCI related to foreign exchange contracts for the nine months ended September 30, 20202021 and 2019,2020, 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 and nine months ended September 30, 20202021 and 20192020 for derivative instruments not designated as hedges under GAAP.

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, other than those in which the counterparty is FICC, do not meet the requirements to net under GAAP.
Derivative asset and liability positions with a single counterparty can be offset against each other in cases where legally enforceable master netting arrangements or similar agreements exist. Derivative assets and liabilities can be further offset by cash collateral received from, and deposited with, the transacting counterparty. The basis for this view is that, upon termination of transactions subject to a master netting arrangement or similar agreement, the individual derivative receivables do not represent resources to which general creditors have rights and individual derivative payables do not represent claims that are equivalent to the claims of general creditors.
Credit risk associated with derivative instruments relates to the failure of the counterparty and the failure of Northern Trust to pay based on the contractual terms of the agreement, and is generally limited to the unrealized fair value gains and losses on these instruments, net of any collateral received or deposited. The amount of credit risk will increase or decrease during the

lives of the instruments as interest rates, foreign exchange rates, or equity prices fluctuate. Northern Trust’s risk is controlled by

Notes to Consolidated Financial Statements (unaudited) (continued)

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 $281.0$142.3 million and $280.8$247.9 million, respectively, as of September 30, 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 $565.5$690.4 million and $766.2$1,648.2 million at September 30, 20202021 and December 31, 2019,2020, respectively. Cash collateral amounts deposited with derivative counterparties on those dates included $184.4$689.0 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 September 30, 20202021 and December 31, 2019,2020, of $381.1$1.4 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.
Note 24 – Subsequent Events
In September 2021, the holders of the Floating Rate Capital Securities Series A and Series B were notified that such securities would be redeemed at the principal amount plus accrued and unpaid interest on October 15, 2021. In 1997, the Corporation established two statutory business trusts, NTC Capital I and NTC Capital II, for the sole purpose of issuing the Floating Rate Capital Securities, Series A due in January 2027 and the Floating Rate Capital Securities, Series B due in April 2027, respectively. The sole assets of the trusts were the subordinated debentures of Northern Trust Corporation that had the same interest rates and maturity dates as the corresponding distribution rates and redemption dates of the Floating Rate Capital Securities. On October 15, 2021, concurrently with the redemption of the Floating Rate Capital Securities Series A and B, the corresponding subordinated debentures were fully redeemed for $278.8 million principal amount plus accrued and unpaid interest, with $154.9 million attributable to the Series A subordinated debenture and $123.9 million attributable to the Series B subordinated debenture.
Item 4. Controls and Procedures
As of September 30, 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 September 30, 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 1921 — 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—and/or may in the future 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 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 ultimate 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 SEC.
