Segment Reporting [Abstract]  
Reporting Segments Reporting Segments
Northern Trust is organized around its two client-focused reporting segments: Asset Servicing and Wealth Management. Asset management and related services are provided to Asset Servicing and Wealth Management clients primarily by the Asset Management business. The revenue and expenses of Asset Management and certain other support functions are allocated fully to Asset Servicing and Wealth Management.
Reporting segment financial information, presented on an internal management-reporting basis, is determined by accounting systems used to allocate revenue and expense to each segment, and incorporates processes for allocating assets, liabilities, equity and the applicable interest income and expense utilizing an FTP methodology. Under the methodology, assets and liabilities receive a funding charge or credit that considers interest rate risk, liquidity risk, and other product characteristics on an instrument level. Additionally, segment information is presented on an FTE basis as management believes an FTE presentation provides a clearer indication of net interest income. The adjustment to an FTE basis has no impact on Net Income.
Revenues, expenses and average assets are allocated to Asset Servicing and Wealth Management, with the exception of non-recurring activities such as certain corporate transactions and costs incurred associated with acquisitions, divestitures, litigation, restructuring, and tax adjustments not directly attributable to a specific reporting segment, which are reported within Other.
In addition to income and expenses associated with non-recurring activities, Other includes expenses for Asset Management, corporate and other support functions not directly incurred by, but ultimately allocated back to Asset Servicing and Wealth Management. Other also includes the FTE adjustments of $5.5 million and $15.8 million for the three and nine months ended September 30, 2025 respectively, and $7.1 million and $21.3 million for the three and nine months ended September 30, 2024, respectively, in order to reconcile the segment results that are reported on an internal management-reporting basis into consolidated results.
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 retrospective basis unless it is impractical to do so.
Effective January 2025, certain operations support activities were moved out of Asset Servicing and Wealth Management in connection with the formation of the Enterprise Chief Operating Office. The Enterprise Chief Operating Office provides operational support to Asset Servicing and Wealth Management. Its expenses are included within Other and are fully allocated to Asset Servicing and Wealth Management. Prior-year segment results have been recast, where practical, to reflect the organizational changes.
Northern Trust’s Chief Operating Decision Maker is the Chief Executive Officer. The Chief Operating Decision Maker uses growth and profitability metrics to assess segments’ performance including segment revenue and income before income taxes. Those same measures are used by the Chief Operating Decision Maker as primary inputs into the allocation of resources in the annual planning process. Allocation of capital to each segment takes into consideration a variety of factors including average loans, average deposits and applicable regulatory capital requirements.
The following table presents the earnings contributions and certain average balances of Northern Trust’s reporting segments for the three- and nine-month periods ended September 30, 2025 and 2024.
