Goodwill is assigned to reporting units, which are operating segments or one level below an operating segment, as of the acquisition date. The Company implemented changes to its organizational structure and internal reporting framework, as further discussed in Note 19 to these Condensed Consolidated Financial Statements.

As discussed further in Note 1 and Note 19 to these Condensed Consolidated Financial Statements, during the third quarter of 2026, Santander completed the acquisition of Webster. The Company recognized preliminary goodwill of approximately $6.5 billion in the transaction. The goodwill recognized is primarily attributable to expanded market presence, expected synergies, operational efficiencies, revenue opportunities, and other strategic benefits, none of which qualify for separate recognition as identifiable intangible assets. The goodwill has been assigned to the Company's reportable segments based upon a preliminary valuation. The estimates and assumptions are subject to change within the measurement period as additional information is obtained.

The following table presents the balance and activity of the Company's goodwill by its reportable segments, except as noted below, for the periods indicated:
