In accordance with the Intangibles - Goodwill and Other topic of the FASB ASC, goodwill is not amortized but is reviewed for potential impairment at the reporting unit level. Management analyzes its goodwill for impairment on an annual basis and between annual tests in certain circumstances, such as upon material adverse changes in legal, business, regulatory and economic factors. An impairment loss is recorded to the extent that the carrying amount of goodwill exceeds its implied fair value. The Company performed an impairment assessment as of December 31, 2016 and 2015 and concluded that there was no impairment to goodwill.

Core deposit intangibles (“CDI”) are evaluated for impairment on an annual basis and between annuals tests if events and circumstances indicate a possible impairment. The CDI is amortized on a straight-line basis over an estimated life of 10 years. The following table sets forth activity for CDI for the years ended December 31, 2016 and 2015 (dollars in thousands). The Company had $7.7 million recorded CDI and $0.5 million amortization expense during 2014.
