Northern (NTRS) Assets Under Custody/Administration

Value of assets held for safekeeping and administration, highlighting the firm’s role as a custodian and the scale of stable, service-based revenue. Large custody balances support predictable fees with lower direct market risk than AUM, but are still exposed to market value swings and client retention trends.

After the 2022 trough, AUC/A has staged a multi-year rebound to record levels, driven by market appreciation, asset-servicing wins and product-led inflows that are boosting recurring fees and pretax margins. Management’s commentary on Asset Servicing momentum, fee growth and targeted AI/product initiatives supports the durability of these gains, but sequential dips, dependence on volatility-driven revenue and some non‑persistent large deposits mean growth can be lumpy—watch market conditions, client retention on big institutional flows, and capital-ratio impacts.
