"Northern Trust's fourth quarter results reflected strong year-over-year growth in net interest income, which more than offset lower trust fees. Expense levels remained elevated as we continued to invest in people and technology to enhance our resiliency and support growth in the business. Reported results included $266 million in charges related to a repositioning of our securities portfolio and, in part, steps we are taking to optimize our cost base and drive greater efficiencies throughout the company. These actions underscore our commitment to improving our profitability. As we look ahead, we are focused on driving organic growth, improving our productivity and further strengthening our foundation."

NORTHERN TRUST CORPORATION FOURTH QUARTER 2022 RESULTS

ACCOUNTING RECLASSIFICATION

Beginning in the first quarter of 2022, Trust, Investment and Other Servicing fees were impacted by the change in classification of certain fees that were previously recorded in Other Operating Income or as a reduction of Other Operating Expense but resulted in no impact to net income. The accounting reclassification increased Trust, Investment and Other Servicing fees in the fourth quarter of 2022 by $14.2 million, with a $5.6 million decrease in Other Operating Income and an $8.6 million increase in Other Operating Expense. The classification changes are deemed to be a better representation of the underlying nature of the business as they are directly tied to client asset levels and the related services are more akin to our core service offerings. Prior-year amounts have not been reclassified.

CLIENT ASSETS
Assets under custody/administration (AUC/A) and assets under management are a driver of the Corporation's trust, investment and other servicing fees, the largest component of noninterest income.

Q4 2022

Decreases in the collective basis reserve were primarily in the commercial and institutional and commercial real estate portfolios, partially offset by an increase in the private client portfolio.

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 generally accepted accounting principles to such measures on an FTE basis, which are non-generally accepted accounting 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.
