The community banking segment's goodwill increased $36.3 million in the first nine months of 2018 primarily as a result of the acquisition of CSC and Veterans First. The specialty finance segment's goodwill decreased $631,000 in the first nine months of 2018 as a result of foreign currency translation adjustments related to the Canadian acquisitions.

At June 30, 2018, the Company utilized a qualitative approach for its annual goodwill impairment test of the community banking segment and determined that it is not more likely than not that an impairment existed at that time. At December 31, 2017, the Company utilized a quantitative approach for its annual goodwill impairment tests of the specialty finance and wealth management segments and determined that no impairment existed at that time. At each reporting date between annual goodwill impairment tests, the Company considers potential indicators of impairment. As of September 30, 2018, the Company identified no such indicators of goodwill impairment within the community banking, specialty finance and wealth management segments.

A summary of intangible assets as of the dates shown and the expected amortization of finite-lived intangible assets as of September 30, 2018 is as follows:

The core deposit intangibles recognized in connection with prior bank acquisitions are amortized over a ten-year period on an accelerated basis. The customer list intangibles recognized in connection with the purchase of life insurance premium finance assets in 2009 are being amortized over an 18-year period on an accelerated basis while the customer list intangibles recognized in connection with prior acquisitions within the wealth management segment are being amortized over a ten-year period on a straight-line basis. Indefinite-lived intangible assets consist of certain trade and domain names recognized in connection with the Veterans First acquisition. As indefinite-lived intangible assets are not amortized, the Company assesses impairment on at least an annual basis.

Total amortization expense associated with finite-lived intangibles totaled approximately $3.2 million and $3.4 million for the nine months ended September 30, 2018 and 2017, respectively.
