A summary of goodwill and other intangibles, as well as the MSR asset, which is included in other assets in the consolidated balance sheets, at December 31 is as follows: 

Management periodically reviews the carrying value of its long-lived and intangible assets to determine if any impairment has occurred, in which case an impairment charge would be recorded as an expense in the period of impairment, or whether changes in circumstances have occurred that would require a revision to the remaining useful life which would impact expense prospectively. In making such determination, management evaluates whether there are any adverse qualitative factors indicating that an impairment may exist, as well as the performance, on an undiscounted basis, of the underlying operations or assets which give rise to the intangible. The Company’s annual assessments indicated no impairment charge on goodwill or other intangibles was required for 2016 or 2015.

Goodwill: Goodwill was $66.7 million at December 31, 2016 and $0.8 million at December 31, 2015. There were additions to the carrying amount of goodwill in 2016 of $0.4 million related to the financial advisor business acquisition and of approximately $65.5 million related to the Baylake acquisition. See Note 2 for additional information on the 2016 acquisitions.

Other intangible assets: Other intangible assets, consisting of core deposit intangibles (related to branch or bank acquisitions) and customer list intangibles (related to the customer relationships acquired in the 2016 financial advisor business acquisition), are amortized over their estimated finite lives. Due to the 2016 acquisitions, there was an addition to the core deposit intangibles and to customer list intangibles. See Note 2 for additional information on the 2016 acquisitions.

The Company periodically evaluates its mortgage servicing rights asset for impairment. As of December 31, 2016, the Company’s assessment does not indicate an impairment on the MSR asset carrying value.

The following table shows the estimated future amortization expense for amortizing intangible assets. The projections are based on existing asset balances, the current interest rate environment and prepayment speeds as of the December 31, 2016. The actual amortization expense the Company recognizes in any given period may be significantly different depending upon acquisition or sale activities, changes in interest rates, prepayment speeds, market conditions, regulatory requirements and events or circumstances that indicate the carrying amount of an asset may not be recoverable.
