SECOND 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
Revenue for the three months ended June 30, 2024 increased $958.4 million, or 55%, to $2.72 billion in the current quarter from $1.76 billion in the prior-year quarter. The current-quarter results include a $878.4 million net gain related to the Visa transactions. For further detail on the Visa transactions, refer to Note 20—Commitments and Contingent Liabilities for further information.
Trust, Investment and Other Servicing Fees increased $69.8 million, or 6%, from $1.10 billion in the prior-year quarter to $1.17 billion in the current quarter, primarily due to favorable markets and new business.
Other Noninterest Income increased $877.2 million from $149.3 million in the prior-year quarter to $1.03 billion in the current quarter. The increase in Other Noninterest Income in the current quarter reflects the net gain related to the Visa transactions, partially offset by a loss recognized as a result of a securities repositioning related to the supplemental pension plan and impairment charges taken on certain investments.
Net Interest Income increased $11.4 million, or 2%, to $522.9 million in the current quarter as compared to $511.5 million in the prior-year quarter, primarily due to higher client deposits, partially offset by higher funding costs.
In the current quarter, there was a Provision for Credit Losses of $8.0 million, as compared to a negative Provision for Credit Losses of $15.5 million in the prior-year quarter. For additional information, refer to the Provision for Credit Losses within “Second Quarter Consolidated Results of Operations” section.
Noninterest Expense increased $202.0 million, or 15%, from $1.33 billion in the prior-year quarter to $1.53 billion in the current quarter, primarily attributable to $182.2 million of restructuring charges and other notable items, including severance-related charges of $85.2 million, a $70 million charitable commitment to the Northern Trust Foundation, higher software amortization acceleration and dispositions, and a legal settlement recorded in the current quarter.
The Provision for Income Taxes in the current quarter totaled $277.5 million, representing an effective tax rate of 23.6%. The Provision for Income Taxes in the prior-year quarter totaled $108.9 million, representing an effective tax rate of 24.7%.
Net Income per diluted common share was $4.34 in the current quarter and $1.56 in the second quarter of 2023. Net Income increased $564.3 million to $896.1 million in the current quarter from $331.8 million in the prior-year quarter. Annualized return on average common equity was 31.2% in the current quarter and 12.4% in the prior-year quarter. The annualized return on average assets was 2.44% in the current quarter as compared to 0.91% in the prior-year quarter.
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.
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 AUM throughout the period. Typically, the asset values used to calculate fee revenue are based on a one-month or one-quarter lag. Securities Lending revenue is affected by market values; the demand for securities to be lent, which drives volumes; and the interest rate spread earned on the investment of cash deposited by investment firms as collateral for securities they have borrowed. The Other fee category in Asset Servicing includes such products as investment risk and analytical services, benefit payments, and other services. Revenue from these products is based generally on the volume of services provided or a fixed fee.
Custody and Fund Administration fees increased from the prior-year quarter, primarily due to favorable markets and new business, partially offset by lower transaction volumes. Investment Management fees increased from the prior-year quarter, primarily due to favorable markets. Securities Lending decreased from the prior-year quarter, primarily due to lower spreads and lower 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 increased from the prior-year quarter, primarily due to favorable markets. Global Family Office fee income increased from the prior-year quarter, primarily due to favorable markets and asset inflows.

Foreign Exchange Trading Income increased compared to the prior-year quarter primarily driven by higher client volumes.
Other Operating Income increased compared to the prior-year quarter, primarily driven by the $878.4 million gain related to the net impact from the Visa transactions in the current quarter, partially offset by a loss recognized as a result of a securities repositioning related to the supplemental pension plan, and impairment charges taken on certain investments.
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 liabilities 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-bearing 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.
