The community banking segment's goodwill increased $13.0 million in the first nine months of 2016 primarily as a result of the acquisition of Generations. The specialty finance segment's goodwill increased $1.2 million in the first nine months of 2016 as a result of foreign currency translation adjustments related to the Canadian acquisitions.

At June 30, 2016, 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 than an impairment existed at that time. The annual goodwill impairment tests of the specialty finance and wealth management segments will be conducted at December 31, 2016. At each reporting date between annual goodwill impairment tests, the Company considers potential indicators of impairment. As of September 30, 2016, the Company identified no such indicators of goodwill impairment.

A summary of finite-lived intangible assets as of the dates shown and the expected amortization as of September 30, 2016 is as follows:
