Goodwill is tested for impairment annually, or more often if circumstances warrant. If, as a result of impairment testing, it is determined that the implied fair value of goodwill is lower than its carrying amount, impairment is indicated, and goodwill must be written down to its implied fair value. Subsequent increases in goodwill value are not recognized in the consolidated financial statements. Goodwill, originally recorded as a result of the Company's acquisition of The Peoples Bank ("TPB") in 2018, totaled $7.4 million as of both September 30, 2022 and December 31, 2021. Goodwill impairment was neither indicated nor recorded during the nine months ended September 30, 2022 or the year ended December 31, 2021.

Core deposit premiums are amortized over a seven-year period and are periodically evaluated, at least annually, as to the recoverability of their carrying value. Core deposit premiums of $2.0 million were recorded during 2018 as part of the TPB acquisition.

The Company’s goodwill and other intangible assets (carrying basis and accumulated amortization) as of September 30, 2022 were as follows:


	September 30, 2022			December 31, 2021
	(Dollars in Thousands)
Goodwill	$	7,435		$	7,435
Core deposit intangible:
Gross carrying amount		2,048			2,048
Accumulated amortization		(1,627	)		(1,414	)
Core deposit intangible, net		421			634
Total	$	7,856		$	8,069

The Company’s estimated remaining amortization expense on intangible assets as of September 30, 2022 was as follows:


	Amortization Expense
	(Dollars in Thousands)
2022	$	55
2023		195
2024		122
2025		49
2026 and thereafter		—
Total	$	421

The net carrying amount of the Company’s core deposit premiums is not considered recoverable if it exceeds the sum of the undiscounted cash flows expected to result from use and eventual disposition. That assessment is based on the carrying amount of the intangible assets subject to amortization at the date on which it is tested for recoverability. Intangible assets subject to amortization are tested by the Company for recoverability whenever events or changes in circumstances indicate that their carrying amount may not be recoverable.
