The Company’s intangible assets consist of core deposits, trademarks, and goodwill arising from previous acquisitions. The Company has determined that core deposit intangibles and trademarks have a finite life and amortizes them over their estimated useful life. Core deposit intangible assets are being amortized over the period of expected benefit, which ranges from 4 to 14 years, using an accelerated method. The trademark intangible acquired through previous acquisitions was amortized over three years using the straight-line method. In accordance with Accounting Standards Codification (“ASC”) 350, Intangibles-Goodwill and Other (“ASC 350”), the Company reviews the carrying value of indefinite lived intangible assets at least annually or more frequently if certain impairment indicators exist. Based on the annual testing during the second quarter of each year and the absence of impairment indicators subsequent to the evaluation date, the Company has recorded no impairment charges to date for goodwill or intangible assets.
