INTANGIBLE ASSETS

The Company’s intangible assets consist of core deposits, goodwill, and other intangibles arising from previous and current 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. On January 1, 2014, the Company completed the acquisition of StellarOne and acquired intangible assets of $29.6 million and recorded $234.1 million of goodwill. On May 31, 2016, the Company completed the acquisition of ODCM and recorded goodwill of $4.7 million and other amortizable intangible assets of $4.5 million. The Company is amortizing these intangible assets over the period of expected benefit, which ranges from 5 to 10 years using a straight-line method. During the current quarter, the Company finalized the valuation of certain amortizable intangible assets which increased the fair value and also impacting the recognized goodwill. The fair values are subject to refinement for up to one year after the closing date of the acquisition.
 
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 2016 and determined that there was no impairment to its goodwill or intangible assets.
