Goodwill and Other Intangible Assets [Abstract] |
Goodwill and Other Intangible Assets | Note 6. Goodwill and Other Intangible Assets ﻿ Goodwill represents the excess of the consideration paid over the fair value of the net assets acquired or the excess of the fair value of the net liabilities assumed over the consideration received in a business combination. The acquisition of the trust and asset management business resulted in goodwill of $43.3 million during the year ended December 31, 2018, and the FNBC transactions resulted in goodwill of $124.3 million during the year ended December 31, 2017. The carrying amount of goodwill was $791.0 million and $745.5 million at December 31, 2018 and 2017, respectively. The Company completed its annual goodwill impairment test as of September 30, 2018 and concluded that there was no impairment of goodwill. ﻿ The Company used the discounted net present value of estimated future cash flows to measure the fair value of its goodwill at September 30, 2018. The valuation technique used by the Company requires significant assumptions. Assumptions are made concerning the economic environment, expected net interest margins, growth rates, and discount rates for cash flows. Changes to these assumptions could result in significantly different results. ﻿ No goodwill impairment charges were recognized during 201 8, 201 7 or 201 6. ﻿ Identifiable intangible assets with finite lives are amortized over the periods benefited and are evaluated for impairment similar to other long-lived assets. The purchase and carrying value s of intangible assets subject to amortization as of December 31, 2018 and 2017 w ere as follows: ﻿ ﻿
