Goodwill represents the excess of the purchase price over the fair value of net assets acquired. Purchase accounting guidance allows for a reasonable period of time following an acquisition for the acquirer to obtain the information necessary to complete the accounting for a business combination. This period is known as the measurement period. Additional measurement period purchase accounting adjustments, primarily related to taxes from the Merger, decreased goodwill by less than $0.1 million in 2016.

Goodwill is reviewed for impairment annually or more frequently if it is determined that a triggering event has occurred. Based upon our qualitative assessment performed for our annual impairment analysis, we concluded that it is more likely than not that the fair value of the reporting units exceeds the carrying value. In general, the overall macroeconomic conditions and more specifically the economic conditions of the banking industry have been very good. Additionally, our overall performance has been good and we did not identify any other facts and circumstances causing us to conclude that it is more likely than not that the fair value of the reporting units would be less than the carrying value.

The following table shows a summary of intangible assets as of the dates presented:



	December 31,
(dollars in thousands)	2017			2016
Gross carrying amount at beginning of year	$	22,114		$	22,114
Additions	—			—
Accumulated amortization	(18,437		)	(17,204		)
Balance at End of Year	$	3,677		$	4,910

Intangible assets as of December 31, 2017 consisted of $3.4 million for core deposits and $0.3 million for insurance contract relationships resulting from acquisitions. We determined the amount of identifiable intangible assets based upon independent core deposit, wealth management and insurance contract valuations. Other intangible assets are evaluated for impairment whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. There were no triggering events in 2017 requiring an impairment analysis to be completed.

Amortization expense on finite-lived intangible assets totaled $1.2 million, $1.6 million and $1.8 million for 2017, 2016 and 2015. The following is a summary of the expected amortization expense for finite-lived intangible assets, assuming no new additions, for each of the five years following December 31, 2017 and thereafter:



(dollars in thousands)	Amount
2018	$	1,013
2019	655
2020	554
2021	477
2022	359
Thereafter	619
Total	$	3,677
