The adjustments to goodwill and intangible assets during the nine months ended September 30, 2020 are primarily attributable to the sale of ZCM, and the acquisitions of Mooreland Partners on July 1, 2019 and B&F Capital Markets on September 3, 2019.

On March 27, 2020, the Company completed the sale of ZCM, a wholly owned asset management subsidiary. The Company recorded a gain on the sale, which included a write-off of allocated goodwill and the remaining net book value of intangible assets.

The allocation of the purchase price of these acquisitions are preliminary and will be finalized upon completion of the analysis of the fair values of the net assets as of the respective acquisition dates 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.

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

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