The adjustments to goodwill and intangible assets included in our Institutional Group segment during the year ended December 31, 2021, are primarily attributable to the acquisition of Vining Sparks on November 1, 2021.

The allocation of the purchase price of the Vining Sparks acquisition is preliminary and will be finalized upon completion of the analysis of the fair values of the net assets as of the acquisition date and the identified intangible assets. The final goodwill recorded on the consolidated statement of financial condition may differ from that reflected herein as a result of future measurement period adjustments and the recording of identified intangible assets. See Note 3 in the notes to our consolidated financial statements for additional information regarding our acquisitions.

The goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of the business, its employees, and customer base.

Amortizable intangible assets consist of acquired customer relationships, trade names, non-compete agreements, core deposits, investment banking backlog, and acquired technology that are amortized over their contractual or determined useful lives.
