Note 1 – Financial Information

Basis of Accounting.The unaudited interim consolidated condensed financial statements of First Horizon National Corporation (“FHN”), including its subsidiaries, havebeen prepared in conformity with accounting principles generally accepted in the United States of America and follow general practices withinthe industries in which it operates. This preparation requires management to make estimates and assumptions that affect the amounts reportedin the financial statements and accompanying notes. These estimates and assumptions are based on information available as of the date of thefinancial statements and could differ from actual results. In the opinion of management, all necessary adjustments have been made for a fair presentation of financial position and results of operations for the periods presented. These adjustments are of a normal recurring nature unless otherwise disclosed in the filing. The operating results for the interim 2013 period are not necessarily indicative of the results that may be expected going forward. For further information, refer to the audited consolidated financial statements in the 2012 Annual Report to shareholders.

Summary of Accounting Changes. Effective January 1, 2013, FHN adopted the provisions of FASB ASU2011-11, “Balance Sheet: Disclosures about Offsetting Assets and Liabilities”. ASU 2011-11 creates new disclosure requirements about the nature of an entity's rights of setoff and related arrangements associated with its financial instruments and derivative instruments. ASU 2011-11 requires entities to disclose both gross and net information about both instruments and transactions eligible for offset in the balance sheet as well as instruments and transactions subject to an agreement similar to a master netting arrangement. The scope of ASU 2011-11 includes derivatives, sale and repurchase agreements/reverse sale and repurchase agreements, and securities borrowing and securities lending arrangements. The provisions of ASU 2011-11 are effective for periods beginning on or after January 1, 2013, with retrospective application to all periods presented in the financial statements required.Additionally in January 2013, FASB issued ASU 2013-01, "Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities", that narrowed the scope of ASU 2011-11. Based on this amendment, ASU 2011-11 applies to derivatives, including bifurcated embedded derivatives, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions that are either offset or subject to an enforceable master netting arrangement or similar agreement. Upon adoption of ASU 2011-11, FHN revised its disclosures accordingly. The adoption of the provisions of ASU 2011-11 had no effect on FHN's statement of condition, results of operations, or cash flows.

Effective January 1, 2013, FHN adopted the provisions of FASB ASU2013-02, "Comprehensive Income: Reporting of Amounts Reclassified out of Accumulated Other Comprehensive Income". ASU 2013-02 requires an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required under U.S. GAAP to be reclassified in its entirety to net income. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures required under U.S. GAAP that provide additional detail about those amounts. ASU 2013-02 does not change the current requirements for reporting net income or other comprehensive income in financial statementsbut modified interim disclosure requirements such that changes in accumulated other comprehensive income must be disclosed in interim filings. The provisions of ASU 2013-02 are effective for periods beginning after December 15, 2012, with prospective application to transactions or modifications of existing transactions that occur on or after the effective date. Upon adoption of the provisions of ASU 2013-02 on January 1, 2013, FHN revised its financial statements and disclosures accordingly.
