7. Intangible Assets

The following table summarizes intangible assets, net of amortization:

	September 30, 2018				December 31, 2017
	Gross Carrying Amount		Accumulated Amortization		Gross Carrying Amount		Accumulated Amortization
	(In thousands)

Amortized intangible assets - core deposits	$	11,916	$	5,207	$	6,118	$	4,532
Unamortized intangible assets - goodwill	$	28,300			$	-

The $5.8 million and $28.3 million increases in the gross carrying amount of core deposit intangibles and goodwill, respectively are the result of our acquisition of TCSB (see note #16). There is no expected residual value relating to the core deposit intangible asset which is expected to be amortized over a period of 10 years (weighted average of 5.2 years). In the third quarter of 2018, goodwill was reduced by $0.7 million (to $28.3 million) related to the collection of a TCSB acquired loan that had been charged off in full prior to the Merger. Because of the status of the collection activities related to this loan at the time of the Merger, we determined that this transaction was a measurement period adjustment and reduced goodwill accordingly.

Amortization of other intangibles has been estimated through 2022 in the following table.
