THIRD QUARTER CONSOLIDATED RESULTS OF OPERATIONS
General
The Corporation is a leading provider of wealth management, asset servicing, asset management and banking solutions to corporations, institutions, families and individuals. The Corporation focuses on managing and servicing client assets through its two client-focused reporting segments: Asset Servicing and Wealth Management. Asset management and related services are provided to Asset Servicing and Wealth Management clients primarily by the Asset Management business. Except where the context requires otherwise, the terms “Northern Trust,” “we,” “us,” “our,” “its,” or similar terms mean the Corporation and its subsidiaries on a consolidated basis.
Overview of Financial Results
Net Income per diluted common share was $1.49 in the current quarter and $1.80 in the third quarter of 2022. Net Income decreased $67.0 million to $327.8 million in the current quarter from $394.8 million in the prior-year quarter. Annualized return on average common equity was 11.6% in the current quarter and 14.9% in the prior-year quarter. The annualized return on average assets was 0.93% in the current quarter as compared to 1.07% in the prior-year quarter. The impacts of a tight labor market are reflected in our Compensation expense. Inflationary pressures were also reflected in higher Equipment and Software expense.
Revenue decreased $28.3 million, or 2%, to $1.73 billion in the current quarter from $1.75 billion in the prior-year quarter. Trust, Investment and Other Servicing Fees increased $33.2 million, or 3%, from $1.08 billion in the prior-year quarter to $1.11 billion in the current quarter, primarily due to lagged favorable markets and favorable currency translation, partially offset by lower transaction volumes. Other Noninterest Income decreased $4.7 million, or 3%, from $163.1 million in the prior-year quarter to $158.4 million in the current quarter, primarily reflecting lower Foreign Exchange Trading Income, partially offset by higher Other Operating Income. Net Interest Income decreased $56.8 million, or 11%, to $456.2 million in the current quarter as compared to $513.0 million in the prior-year quarter, primarily due to lower average earning assets.
There was a $14.0 million Provision for Credit Losses in the current quarter, as compared to a $0.5 million Provision for Credit Losses in the prior-year quarter. The Provision for Credit Losses in the current quarter was primarily due to an increase in the reserve evaluated on a collective basis, driven by a small number of large new loans and renewals and credit quality deterioration of certain commercial real estate (CRE) and commercial and institutional (C&I) loans, partially offset by a net improvement in the overall macroeconomic outlook.
Noninterest Expense increased $48.4 million, or 4%, from $1.23 billion in the prior-year quarter to $1.28 billion in the current quarter, primarily attributable to higher Equipment and Software and Other Operating Expense.
The Provision for Income Taxes in the current quarter totaled $106.5 million, representing an effective tax rate of 24.5%. The Provision for Income Taxes in the prior-year quarter totaled $129.7 million, representing an effective tax rate of 24.7%. The effective tax rate decreased compared to the prior-year quarter primarily due to a lower state tax provision following the resolution of certain state matters.
FDIC Special Assessment
In May 2023, the Federal Deposit Insurance Corporation (FDIC) issued a proposed rule that would impose a special assessment to recover the loss to the Deposit Insurance Fund arising from the protection of uninsured depositors of Silicon Valley Bank and Signature Bank associated with their closures, and the systemic risk determination announced by the FDIC on March 12, 2023. While the timing and amount of any expense recognition are unknown until the proposed rule is finalized, if the FDIC final rule is issued as proposed, the estimated impact of the special assessment to Northern Trust, recognized in Other Operating Expense, would be approximately $80 million.

Trust, Investment and Other Servicing Fees
Trust, Investment and Other Servicing Fees are based primarily on the market value of assets held in custody, managed or serviced; the volume of transactions; securities lending volume and spreads; and fees for other services rendered. Certain market value calculations on which fees are based are performed on a monthly or quarterly basis in arrears.
Northern Trust voluntarily waived $2.2 million of money market fund fees for the three months ended September 30, 2023 and $2.6 million of money market fund fees for the three months ended September 30, 2022.
The components of Trust, Investment and Other Servicing Fees are provided below.

Asset Servicing
Custody and Fund Administration fees, the largest component of Asset Servicing fees, are driven primarily by values of client assets under custody/administration (AUC/A), transaction volumes and the number of accounts. The asset values used to calculate these fees vary depending on the individual fee arrangements negotiated with each client. Custody fees related to asset values are client-specific and are priced based on month-end market values, quarter-end market values, or the average of month-end market values for the quarter. The fund administration fees that are asset-value-related are priced using month-end, quarter-end, or average daily balances. Investment Management fees are based generally on market values of client assets under management throughout the period. Typically, the asset values used to calculate fee revenue are based on a one-month or one-quarter lag. Securities Lending revenue is affected by market values; the demand for securities to be lent, which drives volumes; and the interest rate spread earned on the investment of cash deposited by investment firms as collateral for securities they have borrowed. The Other fee category in Asset Servicing includes such products as investment risk and analytical services, benefit payments, and other services. Revenue from these products is based generally on the volume of services provided or a fixed fee.
Custody and Fund Administration fees increased from the prior-year quarter, primarily due to new business, favorable currency translation, and favorable markets, partially offset by lower transaction volumes.
Wealth Management
Wealth Management fee income is calculated primarily based on market values and is impacted by both one-month and one-quarter lagged asset values. Fee income in the regions (Central, East and West) increased from the prior-year quarter, primarily due to lagged favorable markets, partially offset by product-related asset outflows. Global Family Office fee income increased from the prior-year quarter, primarily due to asset inflows.

Foreign Exchange Trading Income decreased compared to the prior-year quarter primarily driven by an unfavorable impact from foreign exchange swap activity and lower client volumes.
Other Operating Income increased compared to the prior-year quarter, primarily driven by higher income associated with a market value increase in supplemental compensation plans, higher banking and credit-related services fees, and income from valuation adjustments to existing swap agreements related to Visa Inc. Class B common shares, partially offset by lower non-trading foreign exchange income and lower miscellaneous income.

THIRD QUARTER CONSOLIDATED RESULTS OF OPERATIONS (continued)
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 and Deposits with Banks, Federal Reserve and Other Central Bank Deposits, Securities, Loans, and Other Interest-Earning Assets—are financed by a large base of interest-bearing funds that include client deposits, short-term borrowings, Senior Notes and Long-Term Debt. Short-term borrowings include Federal Funds Purchased, Securities Sold Under Agreements to Repurchase, and Other Borrowings. Earning assets are also funded by noninterest-related funds, which include demand deposits and stockholders’ equity. Net Interest Income is subject to variations in the level and mix of earning assets and interest-bearing funds and their relative sensitivity to interest rates. In addition, the levels of nonaccruing assets and client compensating deposit balances used to pay for services impact Net Interest Income.
Net interest margin is the difference between what we earn on our assets and what we pay for deposits and other sources of funding. The direction and level of interest rates are important factors in our earnings. Net interest margin is calculated by dividing annualized Net Interest Income by average interest-earning assets.
Net Interest Income stated on a fully taxable equivalent (FTE) basis is a non-generally accepted accounting principle (GAAP) financial measure that facilitates the analysis of asset yields. Management believes an FTE presentation provides a clearer indication of net interest margins for comparative purposes. When adjusted to an FTE basis, yields on taxable, nontaxable, and partially taxable assets are comparable; however, the adjustment to an FTE basis has no impact on Net Income. A reconciliation of Net Interest Income on a GAAP basis to Net Interest Income on an FTE basis is provided in “Reconciliation to Fully Taxable Equivalent” within this MD&A.
