Goodwill Disclosure [Abstract]
Goodwill	Goodwill FASB ASC Topic 350-20, “Intangibles – Goodwill and Other” requires an annual valuation of the fair value of a reporting unit that has goodwill and a comparison of the fair value to the book value of equity to determine whether the goodwill has been impaired. Goodwill is also required to be tested on an interim basis if an event or circumstance indicates that it is more likely than not that an impairment loss has been incurred. When triggering events or circumstances indicate that goodwill testing is required, an assessment of qualitative factors can be completed before performing the two step goodwill impairment test. ASU 2011-8 provides that if an assessment of qualitative factors determines it is more likely than not that the fair value of a reporting unit exceeds its carrying amount, then the two step goodwill impairment test is not required. We consider First Commonwealth to be one reporting unit. The carrying amount of goodwill as of March 31, 2018 and December 31, 2017 was $255.2 million and $255.4 million, respectively. Goodwill decreased $0.2 million during the three months ended March 31, 2018 as a result of deferred tax adjustments related to the DCB Financial ("DCB") acquisition. No impairment charges on goodwill or other intangible assets were incurred in 2018 or 2017. We test goodwill for impairment as of November 30th each year and again at any quarter-end if any material events occur during a quarter that may affect goodwill. As of March 31, 2018, goodwill was not considered impaired; however, changing economic conditions that may adversely affect our performance, the fair value of our assets and liabilities, or our stock price could result in impairment, which could adversely affect earnings in future periods. Management will continue to monitor events that could impact this conclusion in the future.
