Notes to the Consolidated Condensed Financial Statements (Unaudited)

Note 1 – Financial Information

Basis of Accounting. The unaudited interim consolidated condensed financial statements of First Horizon National Corporation (“FHN”), including its subsidiaries, have been prepared in conformity with accounting principles generally accepted in the United States of America and follow general practices within the industries in which it operates. This preparation requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. These estimates and assumptions are based on information available as of the date of the financial 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 this Quarterly Report on Form 10-Q. The operating results for the interim 2015 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 2014 Annual Report to shareholders, which were filed as Exhibit 13 to FHN’s Annual Report on Form 10-K for the year ended December 31, 2014.

Summary of Accounting Changes. In January 2014, the FASB issued ASU 2014-01, “Equity Method and Joint Ventures: Accounting for Investments in Qualified Affordable Housing Projects.” ASU 2014-01 permits reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using a proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense/(benefit). A reporting entity should evaluate whether the conditions have been met to apply the proportional amortization method to an investment in a qualified affordable housing project through a limited liability entity at the time of initial investment on the basis of facts and circumstances that exist at that time. A reporting entity should reevaluate the conditions upon the occurrence of certain specified events. An investment in a qualified affordable housing project through a limited liability entity should be tested for impairment when there are events or changes in circumstances indicating that it is more likely than not that the carrying amount of the investment will not be realized. For those investments in qualified affordable housing projects not accounted for using the proportional amortization method, the investment should be accounted for as an equity method investment or a cost method investment. The decision to apply the proportional amortization method of accounting is an accounting policy decision that should be applied consistently to all qualifying affordable housing project investments rather than a decision to be applied to individual investments. The provisions of ASU 2014-01 are effective for annual periods, and interim reporting periods within those annual periods, beginning after December 15, 2014.

Effective January 1, 2015, FHN retroactively adopted the requirements of ASU 2014-01 with an election to use the proportional amortization method for all qualifying investments. FHN believes the proportional amortization method better represents the economics of its qualified affordable housing investments and provides users with a better understanding of the returns from such investments when compared to the equity method. FHN will continue to use the equity method for non-qualifying affordable housing investments and its other tax credit investments. The cumulative effects of the retrospective application of the change in amortization method are summarized in the tables below.

Investment balances, including all legally binding commitments to fund future investments, are included in Other assets on the Consolidated Condensed Statements of Condition. A liability is recognized in Other liabilities on the Consolidated Condensed Statement of Condition for all legally binding unfunded commitments to fund qualifying LIHTC investments. Amortization and other write-downs of qualifying LIHTC investments are presented on a net basis as a component of the Provision/(benefit) for income taxes on the Consolidated Condensed Statement of Income, while amortization and write-downs of non-qualifying LIHTC and other tax credit investments are recorded in Other expense. The income tax credits and deductions are recorded as a reduction of income tax expense and a reduction of federal income taxes payable.

In January 2014, the FASB issued ASU 2014-04, “Receivables—Troubled Debt Restructurings by Creditors: Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure.” ASU 2014-04 clarifies that an in-substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, the amendments require interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. ASU 2014-04 is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. An entity is required to adopt ASU 2014-04 using either a modified retrospective transition method or a prospective transition method. Under the modified retrospective transition method, an entity should apply ASU 2014-04 by means of a cumulative-effect adjustment to residential consumer mortgage loans and foreclosed residential real estate properties existing as of the beginning of the annual period for which the amendments are effective. FHN adopted the requirements of ASU 2014-04 prospectively and this did not have a material effect on FHN’s statements of condition, results of operation or cash flows.

In August 2014, the FASB issued ASU 2014-14, “Classification of Certain Government-Guaranteed Mortgage Loan upon Foreclosure.” ASU 2014-14 requires that a mortgage loan be derecognized and that a separate other receivable be recognized upon foreclosure if 1) the loan has a government guarantee that is not separable from the loan before foreclosure, 2) at the time of foreclosure the creditor has the intent to convey the real estate to the guarantor and make a recoverable claim on the guarantee and 3) at the time of foreclosure any amount of the claim that is based on the fair value of the real estate is fixed. For qualifying foreclosures, the amount of the receivable recognized should be measured based on the amount of the loan balance expected to be recovered from the guarantor. ASU 2014-14 is effective for annual and interim periods beginning after December 15, 2014 and may be adopted through either a prospective only approach or through a reclassification from other real estate owned to other receivable on the effective date. FHN adopted the requirements for ASU 2014-14 prospectively for transactions occurring after its effective date and this did not have a material effect on FHN’s statement of condition, results of operation or cash flows.

Accounting Changes Issued but Not Currently Effective

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers.” ASU 2014-09 does not change revenue recognition for financial instruments. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This is accomplished through a five-step recognition framework involving 1) the identification of contracts with customers, 2) identification of performance obligations, 3) determination of the transaction price, 4) allocation of the transaction price to the performance obligations and 5) recognition of revenue as performance obligations are satisfied. Additionally, qualitative and quantitative information is required for disclosure regarding the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. Transition to the new requirements may be made by retroactively revising prior financial statements (with certain practical expedients permitted) or by a cumulative effect through retained earnings. If the latter option is selected, additional disclosures are required for comparability. FHN is evaluating the effects of ASU2014-09 on its revenue recognition practices.

In June 2014, the FASB issued ASU 2014-11, “Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures.” ASU 2014-11 makes two changes to accounting for repurchase agreements. First, it requires secured borrowing accounting for repurchase-to-maturity transactions. Second, it requires separate accounting for a transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty, which will result in secured borrowing accounting for the repurchase agreement. ASU 2014-11 also requires additional disclosures for repurchase transactions that are recognized as secured borrowings, including disaggregation by class of collateral, the remaining contractual tenor of the arrangements and the risks inherent in the agreements. Adoption of ASU 2014-11 will only affect FHN’s disclosures as it does not execute repurchase-to maturity or repurchase financing transactions. These disclosure revisions are effective for annual periods beginning after December 15, 2014, and for interim periods beginning after March 15, 2015.

Note 1 – Financial Information (Continued)

In June 2014, the FASB issued ASU 2014-12, “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period.” ASU 2014-12 requires that a performance target that affects vesting, and that could be achieved after the requisite service period, be treated as a performance condition in determining expense recognition for the award. Thus, compensation cost is recognized over the requisite service period based on the probability of achievement of the performance condition. Expense is adjusted after the requisite service period for changes in the probability of achievement. ASU 2014-12 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. The adoption of ASU 2014-12 will have no effect on FHN.

In August 2014, the FASB issued ASU 2014-15, “Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.” ASU 2014-15 requires an entity’s management to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. If such events or conditions exist, additional disclosures are required and management should evaluate whether its plans sufficiently alleviate the substantial doubt. ASU 2014-15 is effective for the annual period ending after December 15, 2016 and all interim and annual periods thereafter. The provisions of ASU 2014-15 are not anticipated to affect FHN.

In February 2015, the FASB issued ASU 2015-02, “Amendments to the Consolidation Analysis.” ASU 2015-02 revises current consolidation guidance to modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities. ASU 2015-02 also eliminates the presumption that a general partner should consolidate a limited partnership, revises the consolidation analysis for reporting entities that have fee arrangements and related party relationships with variable interest entities, and provides a scope exception for entities with interests in registered money market funds. ASU 2015-02 is effective for annual periods beginning after December 15, 2015 and interim periods within those annual periods. FHN is evaluating the effects of ASU 2015-02 on its current consolidation assessments.

In April 2015, the FASB issued ASU 2015-03, “Simplifying the Presentation of Debt Issuance Costs.” ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented as a direct reduction from the carrying value of that debt liability, consistent with debt discounts. ASU 2015-03 requires application on a retrospective basis, with prior periods revised to reflect the effects of adoption. ASU 2015-03 is effective for annual periods beginning after December 15, 2015 and interim periods within those annual periods. Consistent with current requirements, FHN currently classifies debt issuance costs within Other assets in the Consolidated Condensed Statements of Condition. ASU 2015-03 will have no effect on the recognition of interest expense.

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.

On October 21, 2014, FHN entered into an agreement with TrustAtlantic Financial Corporation (“TrustAtlantic Financial”) by which TrustAtlantic Financial will merge into a subsidiary of FHN. TrustAtlantic Financial owns all the capital stock of TrustAtlantic Bank. Trust Atlantic Financial and TrustAtlantic Bank are headquartered in Raleigh, North Carolina. TrustAtlantic Bank has five branches located in North Carolina in the communities of Raleigh, Cary and Greenville. On December 16, 2014 the parties entered into an amendment to the merger agreement. The transaction is expected to close in the first half of 2015, subject to regulatory approvals and other customary conditions to closing.

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.

The table below provides information on gross gains and gross losses from investment securities for the three months ended March 31:

The following tables provide information on investments within the available-for-sale portfolio that had unrealized losses as of March 31, 2015 and 2014:

FHN has reviewed investment securities that were in unrealized loss positions in accordance with its accounting policy for other than temporary impairment (“OTTI”) and does not consider them other-than-temporarily impaired. For debt securities with unrealized losses, FHN does not intend to sell them and it is more-likely-than-not that FHN will not be required to sell them prior to recovery. The decline in value is primarily attributable to market changes in interest rates and not credit losses. For equity securities, FHN has both the ability and intent to hold these securities for the time necessary to recover the amortized cost.

COMPONENTS OF THE LOAN PORTFOLIO

The loan portfolio is disaggregated into segments and then further disaggregated into classes for certain disclosures. GAAP defines a portfolio segment as the level at which an entity develops and documents a systematic method for determining its allowance for credit losses. A class is generally determined based on the initial measurement attribute (i.e., amortized cost or purchased credit-impaired), risk characteristics of the loan, and FHN’s method for monitoring and assessing credit risk. Commercial loan portfolio segments include commercial, financial and industrial (“C&I”) and commercial real estate (“CRE”). Commercial classes within C&I include general C&I, loans to mortgage companies, the trust preferred loans (“TRUPS”) (i.e. long-term unsecured loans to bank and insurance—related businesses) portfolio and PCI loans. Loans to mortgage companies includes commercial lines of credit to qualified mortgage companies primarily for the temporary warehousing of eligible mortgage loans prior to the borrower’s sale of those mortgage loans to third party investors. Commercial classes within CRE include income CRE, residential CRE and PCI loans. Retail loan portfolio segments include consumer real estate, permanent mortgage, and the credit card and other portfolio. Retail classes include HELOC, real estate (“R/E”) installment and PCI loans within the consumer real estate segment, permanent mortgage (which is both a segment and a class), and credit card and other.

Concentrations

FHN has a concentration of residential real estate loans (32 percent of total loans), the majority of which is in the consumer real estate segment (29 percent of total loans). Loans to finance and insurance companies total $2.0 billion (21 percent of the C&I portfolio, or 12 percent of the total loans). FHN had loans to mortgage companies totaling $1.6 billion (17 percent of the C&I segment, or 10 percent of total loans) as of March 31, 2015. As a result, 38 percent of the C&I segment was sensitive to impacts on the financial services industry.

Note 4 – Loans (Continued)

At March 31, 2015, the ALLL related to PCI loans was $3.1 million compared to $1.9 million at March 31, 2014. A loan loss provision credit of $.2 million was recognized during the three months ended March 31, 2015 as compared to a loan loss provision expense of $1.2 million recognized during the three months ended March 31, 2014. The following table reflects the outstanding principal balance and carrying amounts of the acquired PCI loans as of March 31, 2015 and 2014, and December 31, 2014:
