INTANGIBLE ASSETS

The Company’s intangible assets consist of core deposits, goodwill, and other intangibles arising from acquisitions. The Company has determined that core deposit intangibles have finite lives and amortizes them over their estimated useful lives. Core deposit intangible assets are being amortized over the period of expected benefit, which ranges from 4 to 14 years, using an accelerated method. Other amortizable intangible assets are being amortized over the period of expected benefit, which ranges from 5 to 10 years, using a straight-line method.
 
In accordance with ASC 350, Intangibles-Goodwill and Other, the Company reviews the carrying value of indefinite lived intangible assets at least annually or more frequently if certain impairment indicators exist. The Company performed its annual impairment testing in the second quarter of 2017 and determined that there was no impairment to its goodwill or intangible assets.

Amortization expense of core deposit intangibles for the three and nine months ended September 30, 2017 totaled $1.4 million and $4.3 million, respectively; and the three and nine months ended September 30, 2016 totaled $1.7 million and $5.3 million, respectively. Amortization expense of other intangibles for the three and nine months ended September 30, 2017 totaled $120,000 and $360,000, respectively and $160,000 for the both three and nine months ended September 30, 2016. As of September 30, 2017, the estimated remaining amortization expense of intangibles is as follows (dollars in thousands):
