Goodwill represents the excess of the purchase price over the fair value of net assets acquired. Additional goodwill of $115.9 million was recorded during 2015, for our acquisition of Integrity. Refer to Note 2 Business Combinations for further details on the Integrity acquisition. There were no additions to goodwill in 2014.
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 continued to improve. Additionally, our overall performance has improved 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.

Intangible assets as of December 31, 2015 consisted of $6.1 million for core deposits, $0.1 million for wealth management relationships and $0.4 million for insurance contract relationships resulting from acquisitions. The addition of $5.7 million during 2015 was due to the core deposit intangible asset related to the acquisition of Integrity. 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 2015 requiring an impairment analysis to be completed.
Amortization expense on finite-lived intangible assets totaled $1.8 million, $1.1 million and $1.6 million for 2015, 2014 and 2013. The following is a summary of the expected amortization expense for finite-lived intangibles assets, assuming no new additions, for each of the five years following December 31, 2015:
