Acquisitions and Divestitures [Abstract]
Acquisitions and Divestitures	Note 2 – Acquisitions and Divestitures On May 4, 2017, FHN and Capital Bank Financial Corp. (“Capital Bank”) announced that they had entered into an agreement and plan of merger. Under the agreement FHN will acquire Capital Bank, which is headquartered in Charlotte, North Carolina, and reported approximately $10 billion of assets at March 31, 2017. At the time of announcement Capital Bank operated 193 branches in North and South Carolina, Tennessee, Florida and Virginia. Collectively, Capital Bank shareholders will receive approximately $411 million in cash plus FHN common shares which are expected to represent approximately 29 percent of FHN's outstanding common shares immediately after consummation of the merger. The total transaction value, measured at the time of announcement, was approximately $2.2 billion. The agreement calls for two members of Capital Bank's board of directors to join FHN's board after closing. The transaction is expected to close in fourth quarter 2017, subject to regulatory approvals, approval by shareholders of FHN and of Capital Bank, and other customary conditions. On April 3, 2017, FTN Financial acquired substantially all of the assets and assumed substantially all of the liabilities of Coastal Securities, Inc. (“Coastal”), a national leader in the trading, securitization, and analysis of Small Business Administration (“SBA”) loans, for approximately $130 million in cash. Coastal, which was based in Houston, TX, also traded United States Department of Agriculture (“USDA”) loans and fixed income products and provided municipal underwriting and advisory services to its clients. Coastal’s government-guaranteed loan products, combined with FTN Financial’s existing SBA trading activities, have established an additional major product sector for FTN Financial. On September 16, 2016, FTBNA acquired $537.4 million in unpaid principal balance (“UPB”) of restaurant franchise loans from GE Capital’s Southeast and Southwest regional portfolios. Subsequent to the acquisition the acquired loans were combined with existing FTBNA relationships to establish a franchise finance specialty banking business. In addition to the transactions mentioned above, FHN acquires or divests assets from time to time in transactions that are considered business combination or divestitures but are not material to FHN individually or in the aggregate.
