Acquisitions and Divestitures [Abstract]
Acquisitions and Divestitures	Note 2 – Acquisitions and Divestitures On October 17, 2014, First Tennessee Bank National Association ("FTBNA") purchased thirteen bank branches in Middle and East Tennessee. The fair value of the acquired assets totaled $437.6 million, including $413.4 million in cash, $7.5 million in fixed assets, and $15.7 million of goodwill and intangible assets. FTBNA also assumed $437.2 million of deposits associated with these branches. FTBNA paid a deposit premium of 3.32 percent and acquired an immaterial amount of loans as part of the transaction. In relation to the branch acquisition FHN recorded $4.0 million in goodwill, representing the excess of the estimated fair value of liabilities assumed over the estimated fair value of the assets acquired ( refer to Note 6 – Intangible Assets for additional information), all of which is expected to be deductible for tax purposes. FHN’s operating results for 2015 and 2014 include the impact of branch activity subsequent to the October 17, 2014 closing date. In fourth quarter 2014, FHN entered into a merger agreement with TrustAtlantic Financial Corporation (“TrustAtlantic Financial”). TrustAtlantic Financial owned all the capital stock of TrustAtlantic Bank. TrustAtlantic Financial and TrustAtlantic Bank were headquartered in Raleigh, North Carolina. TrustAtlantic Bank had five branches located in North Carolina in the communities of Raleigh, Cary and Greenville. The holding company transaction closed on October 2, 2015, and as a result FHN took control of TrustAtlantic Bank. TrustAtlantic Bank merged into FTBNA on October 16, 2015 and the TrustAtlantic Bank branches became First Tennessee branches upon closing that merger. The aggregate transaction value of the merger was approximately $95 million. In addition to the transactions mentioned above, FHN acquires or divests assets from time to time in transactions that are considered business combinations or divestitures but are not material to FHN individually or in the aggregate.
