Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets	Goodwill and Intangible Assets At June 30, 2016, the Company had goodwill in the amount of $4,488,000 in connection with various business combinations and purchases. This amount was unchanged from the balance of $4,488,000 at December 31, 2015. While goodwill is not amortized, the Company does conduct periodic impairment analysis on goodwill at least annually or more often as conditions require. Goodwill: The largest component of goodwill is related to the Legacy Bank merger (Campbell reporting unit) completed during February 2007 and totaled approximately $2.9 million at June 30, 2016. The Company completed a "Step 0" analysis for the Campbell reporting unit as of March 31, 2016 and March 31, 2015, with no goodwill impairment. Under the Step 0 analysis, the Company has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, the Company determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step impairment test is unnecessary. Determining the fair value involves a significant amount of judgment, including estimates of changes in revenue growth, changes is discount rates, competitive forces within the industry, and other specific industry and market valuation conditions. Based on the results of the Step 0 impairment analysis at March 31, 2016, the Company concluded that that the fair value of the reporting unit exceeds it carrying value. Therefore, goodwill was not impaired. Core Deposit Intangibles: The core deposit intangible asset related to the Legacy Bank merger, which totaled $3.0 million at the time of merger, was amortized over an estimated life of approximately seven years. At June 30, 2016, there was no remaining carrying value of the core deposit intangible related to the Legacy Bank merger. The Company recognized no amortization expense related to the Campbell operating unit during the six months ended June 30, 2016 and June 30, 2015. At June 30, 2016, there was no remaining carrying value of core deposit intangible related to the Taft branch acquisitions completed in April 2004.
