Item 2.02 Results of Operations and Financial Condition

First Horizon will recognize pre-tax expense of approximately $11 million in the third quarter of 2008 related to Visa's settlement with Discover

First Horizon is a member of the Visa USA network. On October 3, 2007, the Visa organization of affiliated entities completed a series of global restructuring transactions to combine its affiliated operating companies, including Visa USA, under a single holding company, Visa Inc. (Visa). Upon completion of the reorganization, the members of the Visa USA network remained contingently liable for certain Visa litigation matters. On October 27, 2008, Visa announced that it had agreed to settle litigation with Discover Financial Services for $1.9 billion. $1.7 billion of this settlement amount will be paid from an escrow account established as part of Visa's IPO. In connection with this settlement, First Horizon recognized an $11.0 million increase to its contingent liability for Visa litigation matters within noninterest expense. All Visa litigation matters for which FHN has a contingent liability are expected to be settled from an escrow established by Visa. FHN's contingent liability will be reduced as Visa funds the escrow. The timing of these funding events and the related future reversal of FHN's contingent liability are uncertain at this time. Following the additional $11.0 million pre-tax expense in third quarter 2008, the current aggregate liability for First Horizon's proportionate interest in Visa's litigation matters is $36.7 million. In accordance with applicable accounting guidance, the $11.0 million amount should be reflected within the results of operations for third quarter 2008. Due to the timing of Visa's announcement, the amounts included in First Horizon's earnings release dated October 17, 2008, and the related financial supplement and slide presentation did not reflect this adjustment. Accordingly, First Horizon has revised its financial statements to include this adjustment which will be reflected in the third quarter 2008 Form 10-Q, and with this report amends and supplements its earnings release dated October 17, 2008. The revised financial results are summarized in the table presented as an exhibit to Item 9.01 to this Form 8-K. There is no public announcement of the new information in this Report, including its exhibit, other than this Report.

This report, including its exhibit, contains forward-looking statements involving significant risks and uncertainties. A number of important factors could cause actual results to differ materially from those in the forward-looking information. Those factors include general economic and financial market conditions, including expectations of and actual timing and amount of interest rate movements including the slope of the yield curve, competition, customer and investor responses to these conditions, ability to execute business plans, geopolitical developments, natural disasters, and items already mentioned in this report, as well as critical accounting estimates and other factors described in First Horizon's recent filings with the SEC. First Horizon disclaims any obligation to update any such factors or to publicly announce the result of any revisions to any of the forward-looking statements included herein or therein to reflect future events or developments.
