The adjustments to goodwill included in our Institutional Group segment during the nine months ended September 30, 2019 are primarily attributable to the following:

On January 2, 2019, the Company completed the acquisition of First Empire. The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805, “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $22.7 million of goodwill and intangible assets in the consolidated statement of financial condition, which has been allocated to our company’s Institutional Group segment.

On July 1, 2019, the Company completed the acquisition of Mooreland. The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805, “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $37.4 million of goodwill and intangible assets in the consolidated statement of financial condition, which has been allocated to our company’s Institutional Group segment.

On September 3, 2019, the Company completed the acquisition of B&F. The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805, “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $19.6 million of goodwill and intangible assets in the consolidated statement of financial condition, which has been allocated to our company’s Institutional Group segment.

On September 27, 2019, the Company completed the acquisition of certain assets of GKB. The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805, “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $45.2 million of goodwill and intangible assets in the consolidated statement of financial condition, which has been allocated to our company’s Institutional Group segment.

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. See Note 1 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 each respective business, its employees and customer base. Goodwill is expected to be deductible for federal income tax purposes.

The adjustments to goodwill included in our Global Wealth Management segment during the nine months ended September 30, 2019 are primarily attributable to the Business Bank acquisition, which closed on August 31, 2018.

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. Intangible assets subject to amortization as of September 30, 2019 and December 31, 2018 were as follows (in thousands):

	September 30, 2019				December 31, 2018
	Gross Carrying Value		Accumulated Amortization		Gross Carrying Value		Accumulated Amortization
Customer relationships	$	168,110	$	72,794	$	160,745	$	65,254
Trade name		27,131		13,200		26,831		11,755
Core deposits		8,615		2,474		8,615		816
Non-compete agreements		2,714		1,794		2,603		1,452
Investment banking backlog		1,445		1,315		1,431		1,293
	$	208,015	$	91,577	$	200,225	$	80,570

Amortization expense related to intangible assets was $3.8 million and $3.0 million for the three months ended September 30, 2019 and 2018, respectively. Amortization expense related to intangible assets was $11.0 million and $8.7 million for the nine months ended September 30, 2019 and 2018, respectively. Amortization expense is included in other operating expenses in the consolidated statements of operations.

The weighted-average remaining lives of the following intangible assets at September 30, 2019, are: customer relationships, 9.7 years; trade name, 9.0 years; core deposits, 4.4 years; and non-compete agreements, 9.3 years. We have an intangible asset that is not subject to amortization and is, therefore, not included in the table below.
