Financial Information	'
	Notes to the Consolidated Financial Statements
	Note 1 – Summary of Significant Accounting Policies
	Basis of Accounting. The consolidated 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.
	Principles of Consolidation and Basis of Presentation. The consolidated financial statements include the accounts of FHN and other entities in which it has a controlling financial interest. Variable Interest Entities (“VIEs”) for which FHN or a subsidiary has been determined to be the primary beneficiary are also consolidated. The assets and liabilities of FHN's consolidated residential mortgage securitization trusts have been parenthetically disclosed on the face of the Consolidated Statements of Condition as restricted in accordance with the presentation requirements of Accounting Standards Codification (“ASC”) 810, as amended, due to the assets being pledged to settle the trusts' obligations and the trusts' security holders having no recourse to FHN. Affiliates for which FHN is not considered the primary beneficiary and in which FHN does not have a controlling financial interest are accounted for by the equity method. These investments are included in other assets, and FHN's proportionate share of income or loss is included in noninterest income. All significant intercompany transactions and balances have been eliminated. For purposes of comparability, certain prior period amounts have been reclassified to conform to current year presentation.
	Business Combinations. FHN accounts for acquisitions as a business combination in accordance with ASC 805, "Business Combinations," which requires acquired assets and liabilities (other than tax balances) to be recorded at fair value. Business combinations are included in the financial statements from the respective dates of acquisition.
	Revenue Recognition. FHN derives a significant portion of its revenues from fee-based services. Noninterest income from transaction-based fees is generally recognized when the transactions are completed. Noninterest income from service-based fees is generally recognized over the period in which FHN provides the service.
	Deposit Transactions and Cash Management. Deposit transactions include services related to retail and commercial deposit products (such as service charges on checking accounts), cash management products and services such as electronic transaction processing (Automated Clearing House and Electronic Data Interchange), account reconciliation services, cash vault services, lockbox processing, and information reporting to large corporate clients.
	Insurance Commissions. Insurance commissions are derived from the sale of insurance products, including acting as an independent agent to provide life, long-term care, and disability insurance.
	Trust Services and Investment Management. Trust services and investment management fees include investment management, personal trust, employee benefits, and custodial trust services.
	Brokerage, Management Fees and Commissions. Brokerage, management fees and commissions include fees for portfolio management, trade commissions, and annuity and mutual fund sales.
	Statements of Cash Flows. For purposes of these statements, cash and due from banks, federal funds sold, and securities purchased under agreements to resell are considered cash and cash equivalents. Federal funds are usually sold for one-day periods, and securities purchased under agreements to resell are short-term, highly liquid investments.
	Trading Activities. Securities purchased in connection with underwriting or dealer activities (long positions) are carried at fair market value as trading securities. Gains and losses, both realized and unrealized, on these securities are reflected in capital markets noninterest income. Trading liabilities include securities that FHN has sold to other parties but does not own (short positions). FHN is obligated to purchase securities at a future date to cover the short positions. Assets and liabilities for unsettled trades are recorded on the Consolidated Statements of Condition as “Capital markets receivables” or “Capital markets payables.” Beginning in 2013, these balances reflect the netting of certain capital markets receivables and payables, with prior periods revised for comparability. Retained interests from securitizations in the form of excess interest, interest-only and principal-only strips from sales and securitizations of first lien mortgages are recognized at fair value as trading securities with gains and losses, both realized and unrealized, recognized in mortgage banking income. Excess interest represents rights to receive interest from serviced assets that exceed contractually specified rates. Principal-only strips are principal cash flow tranches, and interest-only strips are interest cash flow tranches. Cash receipts and payments are classified in investing activities on the Consolidated Statements of Cash Flows based on the purpose for which such financial assets were retained.
	Investment Securities. Investment securities are reviewed quarterly for possible other-than-temporary impairment (“OTTI”). The review includes an analysis of the facts and circumstances of each individual investment such as the degree of loss, the length of time the fair value has been below cost, the expectation for that security's performance, the creditworthiness of the issuer and FHN's intent and ability to hold the security. Securities that may be sold prior to maturity and equity securities are classified as securities available-for-sale and are carried at fair value. The unrealized gains and losses on securities available-for-sale, including debt securities for which no credit impairment exists, are excluded from earnings and are reported, net of tax, as a component of other comprehensive income within shareholders' equity. Venture capital investments are classified as securities available-for-sale and are carried at fair value with unrealized gains and losses recognized in noninterest income.
	Realized gains and losses for investment securities are determined by the specific identification method and reported in noninterest income. Declines in value judged to be other-than-temporary based on FHN's analysis of the facts and circumstances related to an individual investment, including securities that FHN has the intent to sell, are also determined by the specific identification method, and reported in noninterest income. For impaired debt securities that FHN does not intend to sell and will not be required to sell prior to recovery but for which credit losses exist, the OTTI recognized is separated between the total impairment related to credit losses which is reported in noninterest income, and the impairment related to all other factors which is excluded from earnings and reported, net of tax, as a component of other comprehensive income within shareholders' equity.
	National banks chartered by the federal government are, by law, members of the Federal Reserve System. Each member bank is required to own stock in its regional Federal Reserve Bank ("FRB"). Given this requirement, FRB stock may not be sold, traded, or pledged as collateral for loans. Membership in the Federal Home Loan Bank (“FHLB”) network requires ownership of capital stock. Member banks are entitled to borrow funds from the FHLB and are required to pledge mortgage loans as collateral. Investments in the FHLB are non-transferable and, generally, membership is maintained primarily to provide a source of liquidity as needed.
	Securities Purchased under Resale Agreements and Securities Sold under Repurchase Agreements. FHN enters into short-term purchases of securities under agreements to resell which are accounted for as collateralized financings except where FHN does not have an agreement to sell the same or substantially the same securities before maturity at a fixed or determinable price. As of December 31, 2013 and 2012, and for the three years ended December 31, 2013, all of FHN's securities purchased under agreements to resell were recognized as collateralized financings. Securities delivered under these transactions are delivered to either the dealer custody account at the FRB or to the applicable counterparty. Securities sold under agreements to repurchase are offered to cash management customers as an automated, collateralized investment account. Securities sold are also used by the retail/commercial bank to obtain favorable borrowing rates on its purchased funds. As of December 31, 2013 and 2012, all of FHN's securities sold under agreements to repurchase were secured borrowings.
	Collateral is valued daily and FHN may require counterparties to deposit additional securities or cash as collateral, or FHN may return cash or securities previously pledged by counterparties, or FHN may be required to post additional securities or cash as collateral, based on the contractual requirements for these transactions.
	FHN's capital markets business utilizes securities borrowing arrangements as part of its trading operations. Securities borrowing transactions generally require FHN to deposit cash with the securities lender. The amount of cash advanced is recorded within Securities purchased under agreements to resell in the Consolidated Statements of Condition. These transactions are not considered purchases and the securities borrowed are not recognized by FHN. FHN does not conduct securities lending transactions.
	Loans Held-for-Sale and Securitization and Residual Interests. Prior to fourth quarter 2008, FHN originated first lien mortgage loans (“the warehouse”) for the purpose of selling them in the secondary market through sales to government sponsored enterprises ("GSEs"), through proprietary securitizations, and to a lesser extent through other whole loan sales. In addition, FHN sold certain of the second lien mortgages and home equity lines of credit (“HELOC”) it produced in the secondary market through securitizations and whole loan sales through third quarter 2007. The majority of the mortgage securitization trusts to which FHN transferred loans remains unconsolidated as FHN is deemed not to be the primary beneficiary based on the interests it retained in the trusts. Under ASC 810, as amended, continual reconsideration of conclusions reached regarding which interest holder is the primary beneficiary of a trust is required. See Note 24 – Variable Interest Entities for additional information regarding FHN's consolidated and nonconsolidated mortgage securitization trusts.
	Loans originated or purchased in which management lacks the intent to hold are included in loans held-for-sale in the Consolidated Statements of Condition. FHN has elected the fair value option on a prospective basis for almost all types of mortgage loans originated for sale purposes. Such loans are carried at fair value, with changes in the fair value of these loans recognized in the mortgage banking noninterest income section of the Consolidated Statements of Income. For mortgage loans originated for sale for which the fair value option is elected, loan origination fees are recorded by FHN when earned and related direct loan origination costs are recognized when incurred. See Note 22 – Fair Value of Assets and Liabilities for additional information. FHN accounts for all mortgage loans held-for-sale which were originated prior to 2008 and for mortgage loans held-for-sale for which fair value accounting was not elected at the lower of cost or market value (“LOCOM”).
	Mortgage loans insured by the Federal Housing Administration (“FHA”) and mortgage loans guaranteed by the Veterans Administration (“VA”) were generally securitized through the Government National Mortgage Association (“GNMA”, "Ginnie Mae", or "Ginnie") programs. Generally, conforming conventional loans were securitized through GSEs such as the Federal National Mortgage Association (“FNMA”, "Fannie Mae", or "Fannie") and the Federal Home Loan Mortgage Corporation (“FHLMC”, "Freddie Mac" or "Freddie"). In addition, FHN completed proprietary securitizations of nonconforming first lien and second lien mortgages and HELOC, which do not conform to the requirements for sale or securitization through government agencies. Most of these securitizations are accounted for as sales; those that do not qualify for sale treatment are accounted for as consolidated VIEs or financing arrangements.
	Interests retained from loan sales, including agency securitizations, include mortgage servicing rights ("MSR") and excess interest. Interests retained from proprietary securitizations include MSR and various financial assets which are included in trading securities. All retained interests, including MSR, are carried at fair value. FHN no longer retains financial interests in loans it transfers to third parties.
	Loans. Loans are stated at principal amounts outstanding, net of unearned income. Interest on loans is recognized on an accrual basis at the applicable interest rate on the principal amount outstanding. Loan origination fees and direct costs as well as premiums and discounts are amortized as level yield adjustments over the respective loan terms. Unamortized net fees or costs are recognized upon early repayment of the loans or charge-off. Loan commitment fees are generally deferred and amortized on a straight-line basis over the commitment period. As required by ASC 310, "Receivables", FHN segregates the loan portfolio into segments and then further disaggregates the portfolio into classes for certain disclosures. 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., loans to bank and insurance-related businesses) portfolio and purchase credit impaired ("PCI") loans. Loans to mortgage companies includes commercial lines of credit to qualified mortgage companies exclusively 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 commercial real estate include income CRE, residential CRE and PCI loans. Retail loan portfolio segments include consumer real estate, permanent mortgage, and the credit card and other segment. 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.
	Nonaccrual and Past Due Loans. Generally, for all portfolio segments and classes other than PCI loans, loans are placed on nonaccrual status if it becomes evident that full collection of principal and interest is at risk, impairment has been recognized as a partial charge-off of principal balance, or on a case-by-case basis if FHN continues to receive payments, but there are atypical loan structures or other borrower-specific issues. The determination of whether a troubled debt restructuring ("TDR") is placed on nonaccrual status generally follows the same internal policies and procedures as other portfolio loans. However, FHN will typically place a consumer real estate loan on nonaccrual status if it is 30 or more days delinquent at the time of modification and is determined to be a TDR, except for residential real estate secured loans discharged in bankruptcy ("discharged bankruptcies") that are placed on nonaccrual, regardless of delinquency status. Additionally, current second liens are placed on nonaccrual status if junior to first liens that are 90 days or more delinquent or have been modified into a troubled debt restructuring.
	For commercial and retail loans within each portfolio segment and class that have been placed on nonaccrual status, accrued but uncollected interest is reversed and charged against interest income when the loan is placed on nonaccrual status. Management may elect to continue the accrual of interest when the estimated net realizable value of collateral is sufficient to recover the principal balance and accrued interest. For all portfolio segments and classes other than PCI loans, interest payments received on nonaccrual and impaired loans are normally applied to principal. Once all principal has been received, additional interest payments are recognized on a cash basis as interest income.
	Generally, commercial and retail loans within each portfolio segment and class that have been placed on nonaccrual status can be returned to accrual status if all principal and interest is current and FHN expects full repayment of the remaining contractual principal and interest, or the asset becomes well-secured and is in the process of collection. Also, loans for which all contractual amounts can reasonably be expected to be repaid (including arrearages) within a prudent period, and repayment has been in accordance with the contractual terms for a sustained period (generally for a minimum of six months) can be returned to accrual status. Larger commercial loan balances (outstanding balances greater than $1 million) that are being returned to accrual status are subject to review by the Credit Risk Assurance Group. Residential real estate loans discharged through Chapter 7 bankruptcy and not reaffirmed by the borrower are not returned to accrual status. For current second liens that have been placed on nonaccrual because the first lien is 90 or more days delinquent or is a TDR, the second lien may be returned to accrual upon pay-off or cure of the first lien.
	Charge-offs. For all commercial and retail loan portfolio segments, all losses of principal are charged to the allowance for loan losses ("ALLL") in the period in which the loan is deemed to be uncollectible. A commercial loan is not deemed uncollectible until after review of the individual credit by FHN's Loan Rehab and Recovery Group.
	For consumer loans, the timing of a full or partial charge-off generally depends on the loan type and delinquency status. Generally, for the consumer real estate and permanent mortgage segments, a loan will be either partially or fully charged-off when it becomes 180 days past due. At this time, if the collateral value does not support foreclosure, balances are fully charged-off and other avenues of recovery are pursued. If the collateral value supports foreclosure, the loan is charged-down to net realizable value of the collateral less estimated costs to sell and is placed on nonaccrual status. Beginning in third quarter 2012, for residential real estate loans discharged in Chapter 7 bankruptcy and not reaffirmed by the borrower, the fair value of the collateral position is assessed at the time FHN is made aware of the discharge. Within the credit card and other portfolio segment, credit cards are normally charged-off upon reaching 180 days past due while other non real estate consumer loans are charged-off upon reaching 120 days past due.
	Impaired Loans. Impaired loans include nonaccrual commercial loans greater than $1 million and modified consumer and commercial loans that have been classified as a TDR and are individually measured for impairment under the guidance of ASC 310. See Note 4 – Loans for a discussion of methodologies utilized by FHN to measure impairment.
	Purchase Credit Impaired Loans. ASC 310-30 “Accounting for Certain Loans or Debt Securities Acquired in a Transfer”, provides guidance for acquired loans that have experienced deterioration of credit quality between origination and the time of acquisition and for which the timely collection of the interest and principal is no longer reasonably assured (“PCI loans”). PCI loans are initially recorded at fair value which is estimated by discounting expected cash flows at acquisition date. The expected cash flows include all contractually expected amounts (including interest) and incorporate an estimate for future expected credit losses, pre-payment assumptions, and yield requirement for a market participant, among other things. To the extent possible, certain PCI loans were aggregated into pools with composite interest rate and cash flows expected to be collected for the pool. Aggregation into loan pools is based on common risk characteristics that include similar credit risk or risk ratings, and one or more predominant risk characteristics. Each PCI pool is accounted for as a single unit.
	Accretable yield is the excess of cash flows expected at acquisition over the initial investment in the loan and is recognized in interest income over the remaining life of the loan, or pool of loans. Nonaccretable difference is the difference between the contractually required payments at acquisition and the cash flows expected to be collected at acquisition. FHN estimates expected cash flows for PCI loans on a quarterly basis. Increases in expected cash flows from the last measurement result in reversal of any nonaccretable difference (or allowance for loan losses to the extent any has previously been recorded) with a prospective positive impact on interest income. Decreases to the expected cash flows result in an increase in the allowance for loan losses through increased provision expense.
	FHN does not report PCI loans as nonperforming loans due to the accretion of interest income. Additionally, PCI loans that have been pooled and subsequently modified will not be reported as troubled debt restructurings since the pool is the unit of measurement.
	Allowance for Loan Losses. The ALLL is maintained at a level that management determines is sufficient to absorb estimated probable incurred losses in the loan portfolio. The ALLL is increased by the provision for loan losses and loan recoveries and is decreased by charged-off loans. Reserves are determined in accordance with ASC 450-20-50 "Contingencies - Accruals for Loss Contingencies" and are composed of reserves for commercial loans evaluated based on pools of credit graded loans and reserves for pools of smaller-balance homogeneous retail and commercial loans. The reserve factors applied to these pools are an estimate of probable incurred losses based on management's evaluation of historical net losses from loans with similar characteristics. Additionally, the ALLL includes specific reserves established in accordance with ASC 310-10-35 for loans determined by management to be individually impaired. As of December 31, 2013, the ALLL also included an immaterial reserve associated with purchase credit impaired loans. Management uses analytical models based on loss experience subject to qualitative adjustment to reflect current events, trends, and conditions (including economic considerations and trends) to assess the adequacy of the ALLL as of the end of each reporting period. The nature of the process by which FHN determines the appropriate ALLL requires the exercise of considerable judgment. See Note 4 – Loans for a discussion of FHN's ALLL methodology and a description of the models utilized in the estimation process for the commercial and consumer loan portfolios.
	Key components of the estimation process are as follows: (1) commercial loans determined by management to be individually impaired loans are evaluated individually and specific reserves are determined based on the difference between the outstanding loan amount and the estimated net realizable value of the collateral (if collateral dependent), the present value of expected future cash flows or by observable market prices; (2) individual commercial loans not considered to be individually impaired are segmented based on similar credit risk characteristics and evaluated on a pool basis; (3) reserve rates for the commercial segment are calculated based on historical net charge-offs and are subject to adjustment by management to reflect current events, trends, and conditions (including economic considerations and trends); (4) management's estimate of probable incurred losses reflects the reserve rate applied against the balance of loans in the commercial segment of the loan portfolio; (5) retail loans are generally segmented based on loan type; (6) reserve amounts for each retail portfolio segment are calculated using analytical models based on delinquency trends and net loss experience and are subject to adjustment by management to reflect current events, trends, and conditions (including economic considerations and trends); and (7) the reserve amount for each retail portfolio segment reflects management's estimate of probable incurred losses in the retail segment of the loan portfolio.
	Impairment related to individually impaired loans is measured in accordance with ASC 310-10. For all commercial portfolio segments, commercial TDRs and other individually impaired commercial loans are measured based on the present value of expected future payments discounted at the loan's effective interest rate (“the DCF method”), observable market prices, or for loans that are solely dependent on the collateral for repayment, the estimated fair value of the collateral less estimated costs to sell (net realizable value). Impaired loans also include consumer TDRs. With the exception of discharged bankruptcies which are collateral dependent and charged down to net realizable value, impairment of consumer TDRs is measured using a DCF model. For loans measured using the DCF method or by observable market prices, if the recorded investment in the impaired loan exceeds this amount, a specific allowance is established as a component of the ALLL; however, for impaired collateral-dependent loans FHN generally charges off the full difference between the book value and the estimated net realizable value.
	Future adjustments to the ALLL and methodology may be necessary if economic or other conditions differ substantially from the assumptions used in making the estimates or, if required by regulators, based upon information at the time of their examinations or upon future regulatory guidance. Such adjustments to original estimates, as necessary, are made in the period in which these factors and other relevant considerations indicate that loss levels vary from previous estimates.
	Premises and Equipment. Premises and equipment are carried at cost less accumulated depreciation and amortization and include additions that materially extend the useful lives of existing premises and equipment. All other maintenance and repair expenditures are expensed as incurred. Gains and losses on dispositions are reflected in noninterest income and expense.
	Depreciation and amortization are computed on the straight-line method over the estimated useful lives of the assets and are recorded as noninterest expense. Leasehold improvements are amortized over the lesser of the lease periods or the estimated useful lives using the straight-line method. Useful lives utilized in determining depreciation for furniture, fixtures and equipment and buildings are three to fifteen and seven to forty-five years, respectively.
	Real Estate Acquired by Foreclosure. Real estate acquired by foreclosure consists of properties that have been acquired in satisfaction of debt. These properties are carried at the lower of the outstanding loan amount or estimated fair value less estimated costs to sell the real estate. Losses arising at foreclosure are charged to the appropriate reserve. Properties acquired by foreclosure in compliance with HUD servicing guidelines are included in “Real estate acquired by foreclosure” and are carried at the estimated amount of the underlying government insurance or guarantee. On December 31, 2013, FHN had $25.8 million of these foreclosed properties.
	Required developmental costs associated with foreclosed property under construction are capitalized and included in determining the estimated net realizable value of the property, which is reviewed periodically, and any write-downs are charged against current earnings.
	Intangible Assets. Intangible assets consist of “Other intangible assets” and “Goodwill.” Other intangible assets represents identified intangible assets, including customer lists, acquired contracts, covenants not to compete and premium on purchased deposits, which are amortized over their estimated useful lives, except for those assets related to deposit bases that are primarily amortized over 10 years. Management evaluates whether events or circumstances have occurred that indicate the remaining useful life or carrying value of amortizing intangibles should be revised. Goodwill represents the excess of cost over net assets of acquired subsidiaries less identifiable intangible assets. On an annual basis, FHN assesses goodwill for impairment.
	Derivative Financial Instruments. FHN accounts for derivative financial instruments in accordance with ASC 815 which requires recognition of all derivative instruments on the balance sheet as either an asset or liability measured at fair value through adjustments to either accumulated other comprehensive income within shareholders' equity or current earnings. Fair value is defined as the price that would be received to sell a derivative asset or paid to transfer a derivative liability in an orderly transaction between market participants on the transaction date. Fair value is determined using available market information and appropriate valuation methodologies. FHN has elected to present its derivative assets and liabilities gross on the Consolidated Statements of Condition. Amounts of collateral posted or received have not been netted with the related derivatives.
	FHN prepares written hedge documentation, identifying the risk management objective and designating the derivative instrument as a fair value hedge or cash flow hedge as applicable, or as a free-standing derivative instrument entered into as an economic hedge or to meet customers' needs. All transactions designated as ASC 815 hedges must be assessed at inception and on an ongoing basis as to the effectiveness of the derivative instrument in offsetting changes in fair value or cash flows of the hedged item. For a fair value hedge, changes in the fair value of the derivative instrument and changes in the fair value of the hedged asset or liability attributable to the hedged risk are recognized currently in earnings. For a cash flow hedge, changes in the fair value of the derivative instrument, to the extent that it is effective, are recorded in accumulated other comprehensive income and subsequently reclassified to earnings as the hedged transaction impacts net income. Any ineffective portion of a cash flow hedge is recognized currently in earnings. For free-standing derivative instruments, changes in fair values are recognized currently in earnings. See Note 25 – Derivatives for additional information.
	Cash flows from derivative contracts are reported as operating activities on the Consolidated Statements of Cash Flows.
	Advertising and Public Relations. Advertising and public relations costs are generally expensed as incurred.
	Income Taxes. FHN accounts for income taxes using the asset and liability method pursuant to ASC 740, “Income Taxes,” which requires the recognition of deferred tax assets ("DTAs") and liabilities ("DTLs") for the expected future tax consequences of events that have been included in the financial statements. Under this method, FHN's deferred tax assets and liabilities are determined based on differences between financial statement carrying amounts and the corresponding tax basis of certain assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on DTAs and DTLs is recognized in income in the period that includes the enactment date.
	Additionally, DTAs are subject to a “more likely than not” test to determine whether the full amount of the DTAs should be realized in the financial statements. FHN evaluates the likelihood of realization of the DTA based on both positive and negative evidence available at the time, including (as appropriate) scheduled reversals of DTLs, projected future taxable income, tax planning strategies, and recent financial performance. If the “more likely than not” test is not met, a valuation allowance must be established against the DTA. In the event FHN determines that DTAs are realizable in the future in excess of their net recorded amount, FHN would make an adjustment to the valuation allowance, which would reduce the provision for income taxes.
	FHN's ASC 740 policy is to recognize interest and penalties related to unrecognized tax benefits as a component of income tax expense. Accrued interest and penalties are included within the related tax asset/liability line in the consolidated balance sheet.
	FHN and its eligible subsidiaries are included in a consolidated federal income tax return. FHN files separate returns for subsidiaries that are not eligible to be included in a consolidated federal income tax return. Based on the laws of the applicable state where it conducts business operations, FHN either files consolidated, combined, or separate returns. With few exceptions, FHN is no longer subject to U.S. federal or state and local tax examinations by tax authorities for years before 2009. The Internal Revenue Service (“IRS”) recently completed a limited issue focused examination ("LIFE") for the years ending December 31, 2011 and 2010. All proposed adjustments with respect to examinations of federal returns filed for 2011 and prior years have been settled. FHN is currently under audit in several states.
	Earnings per Share. Earnings per share is computed by dividing net income or loss available to common shareholders by the weighted average number of common shares outstanding for each period. Diluted earnings per share in net income periods is computed by dividing net income available to common shareholders by the weighted average number of common shares adjusted to include the number of additional common shares that would have been outstanding if the potential dilutive common shares resulting from restricted shares or units and options granted under FHN's equity compensation plans and deferred compensation arrangements had been issued. FHN utilizes the treasury stock method in this calculation. Diluted earnings per share does not reflect an adjustment for potentially dilutive shares in periods in which a net loss available to common shareholders exists.
	Equity Compensation. FHN accounts for its employee stock-based compensation plans using the grant date fair value of an award to determine the expense to be recognized over the life of the award. For awards with service vesting criteria, expense is recognized using the straight-line method over the requisite service period (generally the vesting period) and is adjusted for anticipated forfeitures. For awards vesting based on a performance measure, anticipated performance is projected to determine the number of awards expected to vest, and the corresponding aggregate expense is adjusted to reflect the elapsed portion of the performance period. The fair value of equity awards with cash payout requirements, as well as awards for which fair value cannot be estimated at grant date, is remeasured each reporting period through vesting date. Performance awards with pre-grant date achievement criteria are expensed over the period from the start of the performance period through the end of the service vesting term. Awards are amortized using the nonsubstantive vesting methodology which requires that expense associated with awards having only service vesting criteria that continue vesting after retirement be recognized over a period ending no later than an employee's retirement eligibility date.
	Repurchase and Foreclosure Provision. The repurchase and foreclosure provision is the charge to earnings necessary to maintain the liability at a level that reflects management's best estimate of losses associated with the repurchase of loans previously transferred in whole loans sales or securitizations, or make whole requests as of the balance sheet date. See Note 18 – Contingencies and Other Disclosures for discussion related to FHN's obligations to repurchase such loans.
	Legal Costs. Generally, legal costs are expensed as incurred.
	Contingency Accruals. Contingent liabilities arise in the ordinary course of business, including those related to lawsuits, arbitration, mediation, and other forms of litigation. FHN establishes loss contingency liabilities for matters when loss is both probable and reasonably estimable as prescribed by applicable financial accounting guidance. A liability generally is not established when a loss contingency either is not probable or its amount is not reasonably estimable. If loss for a matter is probable and a range of possible loss outcomes is the best estimate available, accounting guidance generally requires a liability to be established at the low end of the range. Expected recoveries from insurance and indemnification arrangements are recognized if they are considered equally as probable and reasonably estimable as the related loss contingency up to the recognized amount of the estimated loss. Gain contingencies and expected recoveries from insurance and indemnification arrangements in excess of the associated recorded estimated losses are recognized when received. Recognized recoveries are recorded as offsets to the related expense in the Consolidated Statements of Income. The favorable resolution of a gain contingency generally results in the recognition of other income in the Consolidated Statements of Income.
	Summary of Accounting Changes. Effective January 1, 2013, FHN adopted the provisions of FASB Accounting Standards Update ("ASU") 2011-11, “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 ASU 2013-02, "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 statements but modifies 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.
	In July 2013, the FASB issued ASU 2013-10, "Derivatives and Hedging: Inclusion of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a Benchmark Interest Rate for Hedge Accounting Purposes." ASU 2013-10 provides guidance on the risks that are permitted to be hedged in a fair value or cash flow hedge. The provisions of ASU 2013-10 permit the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) to be used as a U.S. benchmark interest rate for hedge accounting purposes under ASC 815, in addition to U.S. Treasury rates and the London Interbank Offered Rate ("LIBOR"). The amendments also remove the restriction on using different benchmark rates for similar hedges. The provisions of ASU 2013-10 are effective prospectively for qualifying new or re-designated hedging relationships entered into on or after July 17, 2013. FHN may apply the provisions of ASU 2013-10 to future hedging relationships.
	Effective January 1, 2012, FHN adopted the provisions of FASB ASU 2011-05, “Presentation of Comprehensive Income”. ASU 2011-05 requires that net income and other comprehensive income be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. ASU 2011-05 also provides that regardless of the method used to present comprehensive income, presentation is required on the face of the financial statements of reclassification adjustments for items that are reclassified from other comprehensive income to net income. ASU 2011-05 does not change the current option for entities to present components of other comprehensive income gross or net of the effect of income taxes, provided that such tax effects are presented in the statement in which other comprehensive income is presented or disclosed in the notes to the financial statements. The provisions of ASU 2011-05 are effective for periods beginning after December 15, 2011, with retrospective application to all periods presented in the financial statements required. No transition disclosures are required upon adoption. For interim reporting periods, filers are only required to present total comprehensive income in a single continuous statement or in two consecutive statements. On December 23, 2011, the FASB issued ASU 2011-12, which indefinitely defers the provisions of ASU 2011-05 that require entities to present reclassification adjustments out of accumulated other comprehensive income by component in both the statement in which net income is presented and the statement in which other comprehensive income is presented (for both interim and annual financial statements). Upon adoption of the provisions of ASU 2011-05 and ASU 2011-12 on January 1, 2012, FHN revised its financial statements and disclosures accordingly.
	Effective July 1, 2011, FHN adopted the provisions of FASB ASU 2011-02, “A Creditor's Determination of Whether a Restructuring is a Troubled Debt Restructuring”. ASU 2011-02 provides that a situation in which a market rate is not readily available is an indicator of a troubled debt restructuring, but not a determinative factor, and that an assessment should consider all modified terms of the restructuring when making a final determination regarding a troubled debt restructuring designation. ASU 2011-02 also provides that a modification that results in a temporary or permanent increase to the contractual interest rate cannot be presumed to be a rate that is at or above market. ASU 2011-02 explicitly precludes creditors from using the borrower's effective rate test in ASC 470-60, “Debt – Troubled Debt Restructurings by Debtors” in its evaluation of whether a modification was executed at a market rate. Under the provisions of ASU 2011-02, a borrower that is not currently in default may still be considered to be experiencing financial difficulty when default is probable in the foreseeable future. ASU 2011-02 provides factors that an entity should consider when determining whether a delay in the amount of payments is significant, as insignificant delays in cash flows would not be considered a concession to a borrower under its provisions. Retrospective application to the beginning of the annual period of adoption is required for identification and disclosure purposes, with prospective application for impairment purposes. Disclosure of the total amount of loans and the associated reserves related to those loans that are considered impaired under ASC 310, “Receivables”, as a result of the clarification in guidance is required upon initial application. FHN had previously modified its troubled debt restructuring review process and was already in compliance with the provisions of ASU 2011-02. Therefore, the provisions of ASU 2011-02 had no material effect on FHN's statement of condition, results of operations, cash flows, or required disclosures.
	Effective July 1, 2011, FHN adopted the remaining provisions of FASB ASU 2010-20, “Disclosures about the Credit Quality of Financing Receivables and the Allowance for Credit Losses”, related to the enhanced disclosure requirements for modifications of financing receivables. FHN previously adopted the provisions of ASU 2010-20 for certain disclosures about activity that occurs during a reporting period effective January 1, 2011. Additionally, effective December 31, 2010, FHN adopted the provisions of ASU 2010-20 related to disclosures as of the end of a reporting period, and the amendments to the rollforward of the allowance for credit losses. ASU 2010-20 provides enhanced disclosures related to the credit quality of financing receivables and the allowance for credit losses, and provides that new and existing disclosures should be disaggregated based on how an entity develops its allowance for credit losses and how it manages credit exposures. Under the provisions of ASU 2010-20, additional disclosures required for financing receivables include information regarding the aging of past due receivables, credit quality indicators, and modifications of financing receivables. Comparative disclosures are required only for periods ending subsequent to initial adoption. Upon adoption of the provisions of ASU 2010-20 on September 30, 2011, January 1, 2011, and December 31, 2010, respectively, FHN revised its disclosures accordingly.
	Effective January 1, 2011, FHN adopted the provisions of FASB ASU 2010-06, “Improving Disclosures about Fair Value Measurements”, related to the requirement to provide the activity of purchases, sales, issuances, and settlements related to recurring Level 3 measurements on a gross basis in the Level 3 reconciliation. Effective January 1, 2010, FHN adopted all other provisions of ASU 2010-06. ASU 2010-06 updates ASC 820, “Fair Value Measurements and Disclosures” to require disclosure of significant transfers into and out of Level 1 and Level 2 of the fair value hierarchy, as well as disclosure of an entity's policy for determining when transfers between all levels of the hierarchy are recognized. The updated provisions of ASC 820 also require that fair value measurement disclosures be provided by each “class” of assets and liabilities, and that disclosures providing a description of the valuation techniques and inputs used to measure fair value be included for both recurring and nonrecurring fair value measurements classified as either Level 2 or Level 3. Under ASC 820, as amended, separate disclosure is required in the Level 3 reconciliation of total gains and losses recognized in other comprehensive income. Comparative disclosures are required only for periods ending subsequent to initial adoption. Upon adoption of the amendments to ASC 820 on January 1, 2011, and January 1, 2010, respectively, FHN revised its disclosures accordingly.
	Accounting Changes Issued but Not Currently Effective. In July 2013, the FASB issued ASU 2013-11, "Income Taxes: Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists." ASU 2013-11 provides guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. Generally, ASU 2013-11 requires that an unrecognized tax benefit should reduce a deferred tax asset (“DTA”) that has been established for a net operating loss (“NOL”), a tax credit carryforward, or other similar tax losses. However, if a filer does not have such carryforwards or similar tax losses at the reporting date, the uncertain tax position should be recorded as a liability. If a filer does have a DTA, but is not required by tax law of the applicable jurisdiction to use the DTA to settle additional taxes from the disallowance of a tax position and that is the filers' intent, the uncertain tax position should be recognized as a liability in that situation as well and not netted with the DTA. The assessment of whether a DTA is available is based on the unrecognized tax benefit and DTA that exist at the reporting date and should be made presuming disallowance of the tax position at the reporting date. The provisions of ASU 2013-11 are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013, with early adoption permitted. The provisions of ASU 2013-11 should be applied prospectively to all unrecognized tax benefits that exist at the effective date. Retrospective application is permitted. FHN does not expect the adoption of the provisions of ASU 2013-11 to have a material effect on FHN's statement of condition, results of operations, or cash flows.
	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, and will be applied retrospectively to all periods presented. Early adoption is permitted. FHN is evaluating the effects of ASU 2014-01 on its portfolio of low income housing investments.
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 property 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 can elect 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. Early adoption is permitted. FHN is evaluating the requirements of ASU 2014-04 with respect to its current foreclosure accounting practices.

Acquisitions and Divestitures	'
	Note 2 – Acquisitions and Divestitures
	On June 7, 2013, First Tennessee Bank National Association ("FTBNA") acquired substantially all of the assets and liabilities of Mountain National Bank ("MNB") a community bank headquartered in Sevierville, Tennessee from the Federal Deposit Insurance Corporation ("FDIC"), as receiver, pursuant to a purchase and assumption agreement. Prior to the acquisition, MNB operated 12 branches in Sevier and Blount counties in eastern Tennessee.
	Excluding purchase accounting adjustments, FHN acquired approximately $452 million in assets, including approximately $249 million in loans, and assumed approximately $362 million of MNB deposits. There was no premium associated with the acquired deposits and assets were acquired at a discount of $33 million from book value. FHN did not enter into a loss-sharing agreement with the FDIC associated with the MNB purchase.
	FHN has accounted for the acquisition as a business combination in accordance with ASC 805, "Business Combinations," which requires acquired assets and liabilities (other than tax balances) to be recorded at fair value. Generally, the fair value for the acquired loans was estimated using a discounted cash flow analysis with significant unobservable inputs (Level 3) including adjustments for expected credit losses, prepayment speeds, current market rates for similar loans, and an adjustment for investor-required yield given product-type and various risk characteristics (refer to Note 4 - Loans for additional information).
	The fair value estimates are subject to refinement for up to one year after the closing date of the acquisition as additional information relative to closing date fair values becomes available. In addition, the tax treatment is complex and subject to interpretations that may result in future adjustments of deferred taxes as of the acquisition date.
	In accordance with applicable accounting guidance, significant measurement period adjustments related to acquisitions are presented in the acquired balance at closing, with revision of previously reported amounts.
	The following schedule details significant assets acquired and liabilities assumed from the FDIC for MNB and estimated purchase accounting/fair value adjustments at June 7:

	In relation to the acquisition FHN recorded $7.7 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 7 - Intangible Assets for additional information). Of this amount, $3.3 million is expected to be deductible for tax purposes.
	FHN's operating results for 2013 include the operating results of the acquired assets and assumed liabilities of MNB subsequent to the acquisition on June 7, 2013.
	In 2011, FHN sold First Horizon Insurance, Inc. (“FHI”), the former subsidiary of First Tennessee Bank, a property and casualty insurance agency that served customers in over 40 states, Highland Capital Management Corporation (“Highland”), the former subsidiary of First Horizon National Corporation which provided asset management services, and First Horizon Msaver, Inc. (“Msaver”), the former subsidiary of First Tennessee Bank which provided administrative services for health savings accounts. FHN recognized $4.2 million combined after-tax gains on the sales of FHI and Highland and a $5.7 million after-tax gain related to the sale of Msaver. Additionally, in connection with the agreement to sell FHI, FHN incurred a pre-tax goodwill impairment of $10.1 million which was more than offset by $11.1 million of tax benefits recognized in first quarter 2011 related to the sale. The sales of FHI and Highland closed in second quarter 2011 and the sale of Msaver closed in third quarter 2011. The financial results of these businesses, the goodwill impairment, the gains on sales, and associated tax effects are reflected in the Income/(loss) from discontinued operations, net of tax line on the Consolidated Statements of Income for all periods presented.
	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.

FHN has reviewed investment securities that were in unrealized loss positions in accordance with its accounting policy for 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 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 was 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 C&I and CRE. Commercial classes within C&I include general C&I, loans to mortgage companies, the TRUPs portfolio and PCI loans. Commercial classes within commercial real estate 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, 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 loans secured by residential real estate (39 percent of total loans), the majority of which is in the consumer real estate portfolio (35 percent of total loans). Loans to finance and insurance companies total $1.7 billion (22 percent of the C&I portfolio, or 11 percent of the total loans). FHN had loans to mortgage companies, commercial lines of credit to qualified mortgage companies exclusively for the temporary warehousing of eligible mortgage loans prior to the borrower's sale of those mortgage loans to third party investors, totaling $0.8 billion (10 percent of the C&I portfolio, or 5 percent of total loans) as of December 31, 2013. As a result, 32 percent of the C&I category was sensitive to impacts on the financial services industry.
	Restrictions
	On December 31, 2013, $5.5 billion of commercial loans were pledged to secure potential discount window borrowings from the Federal Reserve Bank. Additionally, as of December 31, 2013, FHN pledged all of its held-to-maturity first and second lien mortgages and HELOCs, excluding restricted real estate loans and secured borrowings, to secure potential borrowings from the FHLB-Cincinnati. Restricted and secured borrowings loans secure borrowings associated with both consolidated and nonconsolidated VIEs. See Note 24—Variable Interest Entities for additional discussion.
	Acquisition
	On June 7, 2013, FHN acquired substantially all of the assets and liabilities of MNB from the FDIC. The acquisition included approximately $249 million of loans. These loans were initially recorded at fair value which incorporates expected credit losses, among other things, in accordance with ASC 805 resulting in no carryover of allowance for loan loss from the acquiree. See Note 2 - Acquisitions and Divestitures for additional information regarding the acquisition. At acquisition, FHN designated certain loans as purchase credit impaired (see discussion below) with the remaining loans accounted for under ASC 310-20, "Nonrefundable Fees and Other Costs". For loans accounted for under ASC 310-20, the difference between the loans' book value to MNB and the estimated fair value at the time of the acquisition will be accreted back into interest income over the remaining contractual life and the subsequent accounting and reporting will be similar to FHN's originated loan portfolio.
	Purchase Credit Impaired Loans
	ASC 310-30 "Accounting for Certain Loans or Debt Securities Acquired in a Transfer", provides guidance for acquired loans that have experienced deterioration of credit quality between origination and the time of acquisition and for which the timely collection of the interest and principal is no longer reasonably assured ("PCI loans"). FHN considered several factors when determining whether a loan met the definition of a PCI loan at the time of acquisition including accrual status, loan grade, delinquency trends, prior partial charge-offs, as well as both originated versus refreshed credit scores and ratios when available.
	PCI loans are initially recorded at fair value which was estimated by discounting expected cash flows at acquisition date. The expected cash flow includes all contractually expected amounts (including interest) and incorporates an estimate for future expected credit losses, pre-payment assumptions, and yield requirement for a market participant, among other things. To the extent possible, certain PCI loans were aggregated into pools with composite interest rate and cash flows expected to be collected for the pool. Aggregation into loan pools is based on common risk characteristics that include similar credit risk or risk ratings, and one or more predominant risk characteristics. Generally, FHN pooled loans with smaller balances and common internal loan grades and portfolio types. Subsequent to the initial accounting at acquisition, each PCI pool is accounted for as a single unit.
	The following table reflects FHN's contractually required payments receivable, cash flows expected to be collected, and the fair value of purchase credit impaired ("PCI") loans at the acquisition date of June 7, 2013.
	(Dollars in thousands)	7-Jun-13
	Contractually required payments including interest	$	79,676
	Less: nonaccretable difference		-23,750
	Cash flows expected to be collected		55,926
	Less: accretable yield		-6,650
	Fair value of loans acquired	$	49,276
	The following table presents a rollforward of the accretable yield for the December 31, 2013:
		Year Ended

	Adjustment for charge-offs		-4
	Increase in accretable yield (a)		9,182
	Balance, end of period	$	13,490
	Includes changes in the accretable yield due to both transfers from the nonaccretable difference and also due to the impact of changes in actual and expected timing of the cash flows.
	At December 31, 2013, the ALLL related to PCI loans was $.8 million while net charge-offs and loan loss provision recognized during 2013 were $.4 million and $1.2 million, respectively. The following table reflects the outstanding principal balance and carrying amounts of the acquired PCI loans as of December 31, 2013:
		31-Dec-13
	(Dollars in thousands)	Ending balance			Unpaid balance
	Commercial, financial and industrial	$	7,077		$	9,169
	Commercial real estate		38,042			53,648
	Consumer real estate		878			1,291
	Credit card and other		12			21
	Total	$	46,009		$	64,129
	Regulatory Focus on Consumer Loan Accounting and Reporting
	In first quarter 2012, the Office of the Comptroller of Currency ("OCC") issued interagency guidance related to ALLL estimation and nonaccrual practices, and risk management policies for junior lien loans. As a result, FHN modified its nonaccrual policies in first quarter 2012, to place current second liens on nonaccrual if the first lien is owned or serviced by FHN and is 90 or more days past due. For non FHN-serviced first liens, in second, third and fourth quarters of 2013, FHN received information from a third party vendor regarding the performance status of those first liens and placed stand-alone second liens on nonaccrual if the first lien was 90 days or more past due or had been modified as a TDR. Because probable incurred losses had been contemplated in the allowance for loan loss estimate in prior quarters, this new information did not result in a significant increase in the ALLL.
	In third quarter 2012, the OCC clarified that residential real estate loans in which personal liability has been discharged through Chapter 7 bankruptcy and not reaffirmed by the borrower are collateral dependent and should be reported as nonaccruing TDR. As a result, FHN charged-down such loans to the net realizable value of the collateral and the remaining balances were reported as nonaccruing TDRs regardless of the loan's delinquency status. The incremental provision expense and net charge-offs due to the implementation of this guidance were approximately $23 million and approximately $33 million in 2012, respectively.
	Because of the composition of FHN's residential real estate portfolios, these changes most significantly impacted the consumer real estate portfolio segment. The level of nonperforming loans and TDRs in the consumer real estate and permanent mortgage portfolios was affected by the regulatory actions discussed above.
	Loan Sales
	In third quarter 2011, FHN executed bulk sales of certain consumer and commercial loans, a significant majority of which were nonperforming. The largest transaction was a sale of permanent mortgages with an unpaid principal balance of approximately $188 million, or $126 million after consideration of partial charge-offs and LOCOM adjustments previously taken on the loans. FHN recognized a loss on sale of $29.8 million which is recognized within the loan loss provision and $40.2 million of net charge-offs associated with this sale. FHN also sold nonperforming commercial loans with unpaid principal balance (“UPB”) of approximately $32 million and $23 million after consideration of amounts already charged off. FHN recognized a loss which is reflected in the loan loss provision of $6.0 million and $7.3 million of net charge-offs related to this commercial loan bulk sale.
	ALLOWANCE FOR LOAN LOSSES
	The ALLL includes the following components: reserves for commercial loans evaluated based on pools of credit graded loans and reserves for pools of smaller-balance homogeneous retail loans, both determined in accordance with ASC 450-20-50. The reserve factors applied to these pools are an estimate of probable incurred losses based on management's evaluation of historical net losses from loans with similar characteristics and are subject to qualitative adjustments by management to reflect current events, trends, and conditions (including economic considerations and trends). The slow economic recovery, performance of the housing market, unemployment levels, the regulatory environment, regulatory guidance, and both positive and negative portfolio segment-specific trends, are examples of additional factors considered by management in determining the ALLL. The ALLL also includes reserves determined in accordance with ASC 310-10-35 for loans determined by management to be individually impaired and an immaterial reserve associated with PCI loans.
	Commercial
	For commercial loans, reserves are established using historical net loss factors by grade level, loan product, and business segment. An assessment of the quality of individual commercial loans is made utilizing credit grades assigned internally based on a dual grading system which estimates both the probability of default (“PD”) and loss severity in the event of default. PD grades range from 1-16 while estimated loss severities, or loss given default (“LGD”) grades, range from 1-12. This credit grading system is intended to identify and measure the credit quality of the loan portfolio by analyzing the migration of loans between grading categories. It is also integral to the estimation methodology utilized in determining the allowance for loan losses since an allowance is established for pools of commercial loans based on the credit grade assigned. The appropriate relationship team performs the process of categorizing commercial loans into the appropriate credit grades, initially as a component of the approval of the loan, and subsequently throughout the life of the loan as part of the servicing regimen. The proper loan grade for larger exposures is confirmed by a senior credit officer in the approval process. To determine the most appropriate credit grade for each loan, the credit risk grading system employs scorecards for particular categories of loans that consist of a number of objective and subjective measures that are weighted in a manner that produces a rank ordering of risk within pass-graded credits. Loan grading discipline is regularly reviewed by Credit Risk Assurance to determine if the process continues to result in accurate loan grading across the portfolio. FHN may utilize availability of guarantors/sponsors to support lending decisions during the credit underwriting process and when determining the assignment of internal loan grades.
Retail
The ALLL for smaller-balance homogenous retail loans is determined based on pools of similar loan types that have similar credit risk characteristics. FHN manages retail loan credit risk on a class basis. Reserves by portfolio are determined using segmented roll-rate models that incorporate various factors including historical delinquency trends, experienced loss frequencies, and experienced loss severities. Generally, reserves for retail loans reflect inherent losses in the portfolio that are expected to be recognized over the following twelve months.
Individually Impaired
Generally, classified nonaccrual commercial loans over $1 million and all commercial and consumer loans classified as TDRs are deemed to be impaired and are individually assessed for impairment measurement in accordance with ASC 310-10-35. For all commercial portfolio segments, TDRs and other individually impaired commercial loans are measured based on the present value of expected future payments discounted at the loan's effective interest rate (“the DCF method”), observable market prices, or for loans that are solely dependent on the collateral for repayment, the net realizable value. For loans measured using the DCF method or by observable market prices, if the recorded investment in the impaired loan exceeds this amount, a specific allowance is established as a component of the ALLL until such time as a loss is expected and recognized; for impaired collateral-dependent loans, FHN will charge off the full difference between the book value and the best estimate of net realizable value.
Generally, the allowance for TDRs in all consumer portfolio segments is determined by estimating the expected future cash flows using the modified interest rate (if an interest rate concession), incorporating payoff and net charge-off rates specific to the TDRs within the portfolio segment being assessed, and discounted using the pre-modification interest rate. The discount rates of variable rate TDRs are adjusted to reflect changes in the interest rate index in which the rates are tied. The discounted cash flows are then compared to the outstanding principal balance in order to determine required reserves. Residential real estate loans discharged through bankruptcy are collateral-dependent and are charged down to net realizable value.
In 2011, FHN estimated TDR reserves for the permanent mortgage portfolio segment by using roll-rate models that estimated reserves for the permanent mortgage portfolio both with and without TDRs. Additionally, a qualitative factor representing the incremental inherent loss for such TDRs was applied to estimate the total required reserves for permanent mortgage TDRs. In first quarter 2012, FHN began utilizing a DCF model for estimating such reserves consistent with all other retail portfolio segments.

Impaired Loans
The following tables provide information at December 31, 2013 and 2012, by class related to individually impaired loans and consumer TDR's. Recorded investment is defined as the amount of the investment in a loan, before valuation allowance but which does reflect any direct write-down of the investment. For purposes of this disclosure, PCI loans and LOCOM have been excluded.

Asset Quality Indicators
As previously discussed, FHN employs a dual grade commercial risk grading methodology to assign an estimate for PD and the LGD for each commercial loan using factors specific to various industry, portfolio, or product segments that result in a rank ordering of risk and the assignment of grades PD 1 to PD 16. Each PD grade corresponds to an estimated one-year default probability percentage; a PD 1 has the lowest expected default probability, and probabilities increase as grades progress down the scale. PD 1 through PD 12 are “pass” grades. PD grades 13-16 correspond to the regulatory-defined categories of special mention (13), substandard (14), doubtful (15), and loss (16). Pass loan grades are required to be reassessed annually or earlier whenever there has been a material change in the financial condition of the borrower or risk characteristics of the relationship. All commercial loans over $1 million and certain commercial loans over $500,000 that are graded 13 or worse are reassessed on a quarterly basis. LGD grades are assigned based on a scale of 1-12 and represent FHN's expected recovery based on collateral type in the event a loan defaults.
The following tables provide the balances of commercial loan portfolio classes with associated allowance, disaggregated by PD grade as of December 31, 2013 and 2012:

The retail portfolio is comprised primarily of smaller-balance loans which are very similar in nature in that most are standard products and are backed by residential real estate. Because of the similarities of retail loan-types, FHN is able to utilize the Fair Isaac Corporation (“FICO”) score, among other attributes, to assess the quality of consumer borrowers. FICO scores are refreshed on a quarterly basis in an attempt to reflect the recent risk profile of the borrowers. Accruing delinquency amounts are indicators of asset quality within the credit card and other retail portfolio.
The following tables reflect period-end balances and average FICO scores by origination vintage for the HELOC, real estate installment, and permanent mortgage classes of loans as of December 31, 2013 and 2012:

Troubled Debt Restructurings
As part of FHN's ongoing risk management practices, FHN attempts to work with borrowers when necessary to extend or modify loan terms to better align with their current ability to repay. Extensions and modifications to loans are made in accordance with internal policies and guidelines which conform to regulatory guidance. Each occurrence is unique to the borrower and is evaluated separately. FHN considers regulatory guidelines when restructuring loans to ensure that prudent lending practices are followed. As such, qualification criteria and payment terms consider the borrower's current and prospective ability to comply with the modified terms of the loan.
A modification is classified as a TDR if the borrower is experiencing financial difficulty and it is determined that FHN has granted a concession to the borrower. FHN may determine that a borrower is experiencing financial difficulty if the borrower is currently in default on any of its debt, or if it is probable that a borrower may default in the foreseeable future. Many aspects of a borrower's financial situation are assessed when determining whether they are experiencing financial difficulty, particularly as it relates to commercial borrowers due to the complex nature of loan structures, business/industry risk, and borrower/guarantor structures. Concessions could include reductions of interest rates, extension of the maturity date at a rate lower than current market rate for a new loan with similar risk, reduction of accrued interest, or principal forgiveness. When evaluating whether a concession has been granted, FHN also considers whether the borrower has provided additional collateral or guarantors, among other things, and whether such additions adequately compensate FHN for the restructured terms. The assessments of whether a borrower is experiencing (or is likely to experience) financial difficulty and whether a concession has been granted is subjective in nature and management's judgment is required when determining whether a modification is classified as a TDR.
For all classes within the commercial portfolio segment, TDRs are typically modified through forbearance agreements (generally 6 to 12 months). Forbearance agreements could include reduced interest rates, reduced payments, release of guarantor in exchange for payment, or entering into short sale agreements. FHN's proprietary modification programs for consumer loans are generally structured using parameters of U.S. government-sponsored programs such as Home Affordable Modification Program (“HAMP”). Within the HELOC and R/E installment loans classes of the consumer portfolio segment, TDRs are typically modified by reducing the interest rate (in increments of 25 basis points to a minimum of 1 percent for up to 5 years) and a possible maturity date extension to reach an affordable housing debt ratio. Permanent mortgage TDRs are typically modified by reducing the interest rate (in increments of 25 basis points to a minimum of 2 percent for up to 5 years) and a possible maturity date extension to reach an affordable housing debt ratio. After 5 years the interest rate steps up 1 percent every year thereafter until it reaches the Federal Home Loan Mortgage Corporation ("Freddie Mac," "Freddie," or "FHLMC") Weekly Survey Rate cap. Contractual maturities may be extended to 40 years on permanent mortgages and to 30 years for consumer real estate loans. Within the credit card class of the consumer portfolio segment, TDRs are typically modified through either a short-term credit card hardship program or a longer-term credit card workout program. In the credit card hardship program, borrowers may be granted rate and payment reductions for 6 months to 1 year. In the credit card workout program, customers are granted a rate reduction to 0 percent and term extensions for up to 5 years to pay off the remaining balance.
In 2012, the OCC clarified that the discharge of personal liability through bankruptcy proceedings should be considered a concession. As a result, FHN classified all non-reaffirmed residential real estate loans after bankruptcy as nonaccruing TDRs in third quarter 2012.
On December 31, 2013 and 2012, FHN had $352.3 million and $358.0 million portfolio loans classified as TDRs, respectively. For TDRs in the loan portfolio, FHN had loan loss reserves of $64.6 million and $58.9 million, or 18 percent as of December 31, 2013, and 16 percent as of December 31, 2012. Additionally, FHN had restructured $193.9 million and $178.2 million of loans held-for-sale as of December 31, 2013 and 2012, respectively.
The following table reflects portfolio loans that were classified as TDRs during the years ended December 31, 2013 and 2012:

The following table presents TDRs which re-defaulted during 2013 and 2012 and as to which the modification occurred 12 months or less prior to the re-default. Financing receivables that became classified as TDRs within the previous 12 months and for which there was a payment default during the period are calculated by first identifying TDRs that were in default during the period and then determining whether they were modified within the 12 months prior to the default. For purposes of this disclosure, FHN generally defines payment default as a loan being 30 or more days past due.

The determination of whether a TDR is placed on nonaccrual status generally follows the same internal policies and procedures as other portfolio loans. However, FHN will typically place a consumer real estate loan on nonaccrual status if it is 30 or more days delinquent upon modification into a TDR. For commercial loans, nonaccrual TDRs that are reasonably assured of repayment according to their modified terms may be returned to accrual status by FHN upon a detailed credit evaluation of the borrower's financial condition and prospects for repayment under the revised terms. For consumer loans, FHN's evaluation supporting the decision to return a modified loan to accrual status includes consideration of the borrower's sustained historical repayment performance for a reasonable period prior to the date on which the loan is returned to accrual status, which is generally a minimum of six months. FHN may also consider a borrower's sustained historical repayment performance for a reasonable time prior to the restructuring in assessing whether the borrower can meet the restructured terms, as it may indicate that the borrower is capable of servicing the level of debt under the modified terms. Otherwise, FHN will continue to classify restructured loans as nonaccrual. Consistent with regulatory guidance, upon sustained performance and classification as a TDR over FHN's year-end, the loan will be removed from TDR status as long as the modified terms were market-based at the time of modification.

Mortgage Servicing Rights [Abstract]	'
Mortgage Servicing Rights	'
	Note 6 – Mortgage Servicing Rights
	FHN recognizes all classes of mortgage servicing rights (“MSR”) at fair value. Classes of MSR are established based on market inputs used to determine the fair value of the servicing asset and FHN's risk management practices. See Note 22 – Fair Value of Assets & Liabilities, the “Determination of Fair Value” section for a discussion of FHN's MSR valuation methodology. In third quarter 2013, FHN agreed to sell substantially all remaining legacy mortgage servicing which will result in de-recognition of substantially all first lien MSR. Transfers of servicing began in fourth quarter 2013 and were substantially completed in first quarter 2014. See Note 25 – Derivatives for a discussion of how FHN hedged the fair value of MSR prior to signing the definitive sales agreement. The balance of MSR included on the Consolidated Statements of Condition represents the rights to service approximately $10 billion and $19 billion of mortgage loans on December 31, 2013 and 2012, respectively, for which a servicing right has been capitalized.
	Following is a summary of changes in capitalized MSR as of December 31, 2013 and 2012:
	(Dollars in thousands)	First Liens		Second Liens		HELOC		Total
	Fair value on January 1, 2012	$	140,724	$	231	$	3,114	$	144,069

	Other changes in fair value		-91		45		44		-2
	Fair value on December 31, 2013	$	70,341	$	161	$	2,291	$	72,793
	Servicing, late, and other ancillary fees recognized within mortgage banking income were $41.9 million, $58.9 million and $70.2 million for the years ended December 31, 2013, 2012 and 2011, respectively. Servicing, late, and other ancillary fees recognized within other income and commissions were $1.7 million, $2.0 million and $2.4 million for the years ended December 31, 2013, 2012 and 2011, respectively.
	MSR declined $41.5 million during 2013 compared to a decline of $29.8 million in 2012, primarily due to the transfer of servicing associated with the MSR sales, which more than offset a $20.1 million increase in value reflecting higher interest rates and the terms of the servicing sale agreement. In 2012, a decline in mortgage rates resulted in elevated prepayment speed assumptions and a corresponding decrease in MSR value of $5.1 million. In first quarter 2013 and third quarter 2012, FHN exercised cleanup calls related to proprietary securitization trusts that had previously been securitized with servicing retained. Upon exercise, the associated mortgage loans were repurchased and are now included on the Consolidated Statements of Condition. Accordingly, FHN derecognized the remaining MSR associated with these loans. The remaining declines in MSR are attributable to natural run-off.
	Prior to servicing sales completed in fourth quarter 2013, FHN serviced a portfolio of mortgage loans related to transfers by other parties utilizing securitization trusts. The servicing assets represented FHN's sole interest in these transactions. The total MSR recognized by FHN related to these transactions was $1.5 million at December 31, 2012. The aggregate principal balance serviced by FHN for these transactions was $.3 billion at December 31, 2012. FHN had no obligation to provide financial support and did not provide any form of support to the related trusts. The MSR recognized by FHN was included in the first lien mortgage loans column within the rollforward of MSR.
	In prior periods, FHN transferred MSR to third parties in transactions that did not qualify for sales treatment due to certain recourse provisions that were included within the sale agreements. In fourth quarter 2013, FHN determined that these provisions had lapsed and the balances related to these transactions were removed from FHN's Consolidated Statements of Condition. The removal of these MSR are shown on the rollforward of MSR in the reductions due to sales of MSRs line within the first liens mortgage column. On December 31, 2012, FHN had $11.2 million of MSR related to these transactions, which were included within the first liens mortgage loans column of the rollforward of MSR. The proceeds from these transfers were recognized within Other short-term borrowings in the Consolidated Statements of Condition.

	See Note 27 – Restructuring, Repositioning, and Efficiency for further details related to goodwill impairments.
	See Note 2 – Acquisitions and Divestitures for further details regarding goodwill related to acquisitions and divestitures.
	The gross carrying amount of other intangible assets subject to amortization is $61.1 million on December 31, 2013, net of $39.1 million of accumulated amortization. Estimated aggregate amortization expense is expected to be $3.9 million, $3.7 million, $3.6 million, $3.3 million, and $3.2 million for the twelve-month periods of 2014, 2015, 2016, 2017, and 2018, respectively.
	The agreement to sell FHI resulted in a pre-tax goodwill impairment of $10.1 million in first quarter 2011. In second quarter 2011, the remaining $16.4 million of goodwill was removed in conjunction with the divestiture. The sale of Msaver during third quarter 2011 resulted in the removal of $2.0 million of goodwill. During 2011, FHN also recognized $2.2 million and $.1 million of other intangible asset write-offs related to the FHI and Msaver divestitures, respectively.
	The following is a summary of gross goodwill and accumulated impairment losses and write-offs detailed by reportable segments included in the Consolidated Statements of Condition through December 31, 2013. Gross goodwill, accumulated impairments, and accumulated divestiture related write-offs were determined beginning on January 1, 2002, when a change in accounting requirements resulted in goodwill being assessed for impairment rather than being amortized.

Short-Term Borrowings [Text Block]	'
	Note 9 – Short-term Borrowings
	Short-term borrowings include federal funds purchased and securities sold under agreements to repurchase, trading liabilities, and other borrowed funds.
	Federal funds purchased and securities sold under agreements to repurchase generally have maturities of less than 90 days. Trading liabilities, which represent short positions in securities, are generally held for less than 90 days. Other short-term borrowings have original maturities of one year or less. On December 31, 2013, capital markets trading securities with a fair value of $122.1 million were pledged to secure other short-term borrowings.
	The detail of these borrowings for the years 2013, 2012 and 2011 is presented in the following table:

Guaranteed Preferred Beneficial Interests In Junior Subordinated Debentures [Text Block]	'
	Note 11 – Guaranteed Preferred Beneficial Interest in First Horizon's Junior Subordinated Debentures
	In 2004 First Tennessee Capital II (“Capital II”), a Delaware business trust wholly owned by FHN, issued $200 million of Capital Securities, Series B at 6.30 percent per annum. The proceeds were loaned to FHN as junior subordinated debt. FHN has, through various contractual arrangements, fully and unconditionally guaranteed all of Capital II's obligations with respect to the capital securities. The sole asset of Capital II is $206 million of junior subordinated debentures issued by FHN. These junior subordinated debentures also carry an interest rate of 6.30 percent. Both the capital securities of Capital II and the junior subordinated debentures of FHN will mature on April 15, 2034; however, FHN has the option to redeem both prior to maturity. The junior subordinated debentures are included in the Consolidated Statements of Condition in Term borrowings (see Note 10 – Term Borrowings). At year end, the capital securities fully qualified as Tier 1 capital. Tier 1 capital treatment for these securities will begin phasing out after 2014 and entirely after 2015.
	In 1996 First Tennessee Capital I ("Capital I"), a Delaware business trust wholly owned by FHN, issued $100 million of Capital Securities, Series A at 8.07 percent. Under regulatory capital guidelines, the capital securities qualified as Tier 1 capital. In January 2011, FHN redeemed the associated subordinate debentures and capital securities in full. The redemption notice was provided in December 2010, at which point the capital securities were no longer eligible for Tier 1 capital treatment.

	FHN Preferred Stock and Warrant
	In fourth quarter 2008 FHN sold 866,540 preferred shares of Fixed Rate Cumulative Perpetual Preferred Stock, CPP, along with a Warrant to purchase common stock to the U.S. Treasury ("UST") as part of its Capital Purchase Program (“Capital Purchase Program”) administered under the Troubled Asset Relief Program (“TARP”). The Warrant was immediately exercisable and was set to expire ten years after issuance. After adjustment for stock dividends distributed through January 1, 2011, the Warrant covered 14,842,321 common shares at a purchase price of $8.757 per share. The preferred shares were repurchased in 2010 and in first quarter 2011, FHN completed the purchase and cancellation of the Warrant to purchase common stock. FHN purchased the Warrant from the UST for $79.7 million, and then canceled it. The UST no longer holds any securities of FHN under the Capital Purchase Program.
	On January 31, 2013, FHN issued 1,000 shares having an aggregate liquidation preference of $100 million of Series A Non-Cumulative Perpetual Preferred Stock for net proceeds of approximately $96 million. Dividends on the Series A Preferred Stock, if declared, accrue and are payable quarterly, in arrears, at a rate of 6.20 percent per annum. For the issuance, FHN issued depositary shares, each of which represents a 1/4000th fractional ownership interest in a share of FHN's preferred stock. These securities qualify as Tier 1 capital.
	Subsidiary Preferred Stock
	In 2000 FT Real Estate Securities Company, Inc. (“FTRESC”), an indirect subsidiary of FHN, issued 50 shares of 9.50 percent Cumulative Preferred Stock, Class B (“Class B Preferred Shares”), with a liquidation preference of $1.0 million per share; of those, 47 shares were issued to nonaffiliates. These securities qualify as Tier 2 capital and are presented in the Consolidated Statements of Condition as Term borrowings. FTRESC is a real estate investment trust (“REIT”) established for the purpose of acquiring, holding, and managing real estate mortgage assets. Dividends on the Class B Preferred Shares are cumulative and are payable semi-annually.
	The Class B Preferred Shares are mandatorily redeemable on March 31, 2031, and redeemable at the discretion of FTRESC in the event that the Class B Preferred Shares cannot be accounted for as Tier 2 regulatory capital or there is more than an insubstantial risk that dividends paid with respect to the Class B Preferred Shares will not be fully deductible for tax purposes. They are not subject to any sinking fund and are not convertible into any other securities of FTRESC, FHN, or any of its subsidiaries. The shares are, however, automatically exchanged at the direction of the Office of the Comptroller of the Currency for preferred stock of FTBNA, having substantially the same terms as the Class B Preferred Shares in the event FTBNA becomes undercapitalized, insolvent, or in danger of becoming undercapitalized.
	FTRESC also has outstanding Cumulative Perpetual Preferred Stock, Class A, which has been recognized as Noncontrolling interest on the Consolidated Statements of Condition, along with Class B Cumulative Perpetual Preferred Stock issued by First Horizon Preferred Funding, Inc. and First Horizon Preferred Funding II, Inc. Other preferred shares are outstanding but are owned by FHN subsidiaries and are eliminated in consolidation. For all periods presented, the amount included within Noncontrolling interest related to preferred shares issued from these subsidiaries was $.3 million. On January 1, 2013, First Horizon Preferred Funding III, Inc. issued $.1 million of Cumulative Perpetual Preferred Stock, Class A, which is attributable to the noncontrolling interest-holders. During 2013, in connection with the acquisition of MNB, FHN obtained a controlling interest in a subsidiary of MNB which had issued Cumulative Perpetual Preferred Stock, Class A. This $.2 million non-controlling interest is now considered to be issued by First Horizon Preferred Lending IV.
	In 2005 FTBNA issued 300,000 shares of Class A Non-Cumulative Perpetual Preferred Stock (“Class A Preferred Stock”) with a liquidation preference of $1,000 per share. Dividends on the Class A Preferred Stock, if declared, accrue and are payable each quarter, in arrears, at a floating rate equal to the greater of the three month LIBOR rate plus .85 percent or 3.75 percent per annum. These securities qualify as Tier 1 capital. On December 31, 2013, 2012, and 2011, $294.8 million of Class A Preferred Stock was recognized as Noncontrolling interest on the Consolidated Statements of Condition for all periods.

Regulatory Capital Requirements [Abstract]	'
Regulatory Capital And Restrictions	'
	Note 13 – Regulatory Capital and Restrictions
	Regulatory Capital. FHN is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on FHN's financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, specific capital guidelines that involve quantitative measures of assets, liabilities, and certain derivatives as calculated under regulatory accounting practices must be met. Capital amounts and classification are also subject to qualitative judgment by the regulators about components, risk weightings, and other factors. Quantitative measures established by regulation to ensure capital adequacy require FHN to maintain minimum amounts and ratios of Total and Tier 1 capital to risk-weighted assets, and of Tier 1 capital to average assets (“Leverage”). Management believes that, as of December 31, 2013, FHN met all capital adequacy requirements to which it was subject.
	The actual capital amounts and ratios of FHN and FTBNA are presented in the table below. In addition, FTBNA must also calculate its capital ratios after excluding financial subsidiaries as defined by the Gramm-Leach-Bliley Act of 1999. Based on this calculation, FTBNA's Total Capital, Tier 1 Capital, and Leverage ratios were 16.84 percent, 15.43 percent, and 12.33 percent, respectively, on December 31, 2013, and were 16.76 percent, 14.82 percent, and 12.24 percent, respectively, on December 31, 2012.

	Restrictions on cash and due from banks. Under the Federal Reserve Act and Regulation D, FTBNA is required to maintain a certain amount of cash reserves. On December 31, 2013 and 2012, FTBNA's required reserves were $115.2 million and $248.4 million, respectively. At the end of 2013 and 2012, this requirement was met with $137.8 million and $139.4 million in vault cash, respectively, in addition to Federal Reserve Bank deposits. Vault cash is reflected in Cash and due from banks on the Consolidated Statements of Condition and Federal Reserve Bank deposits are reflected as Interest-bearing cash.
	Restrictions on dividends. Cash dividends are paid by FHN from its assets, which are mainly provided by dividends from its subsidiaries. Certain regulatory restrictions exist regarding the ability of FTBNA to transfer funds to FHN in the form of cash, dividends, loans, or advances. As of December 31, 2013, FTBNA had undivided profits of $1.0 billion, none of which was available for distribution to FHN as dividends without prior regulatory approval. At any given time, the pertinent portions of those regulatory restrictions allow FTBNA to declare preferred or common dividends without prior regulatory approval in an amount equal to FTBNA's retained net income for the two most recent completed years plus the current year to date. For any period, FTBNA's 'retained net income' generally is equal to FTBNA's regulatory net income reduced by the preferred and common dividends declared by FTBNA. Excess dividends in either of the two most recent completed years may be offset with available retained net income in the two years immediately preceding it. Applying the applicable rules, FTBNA's total amount available for dividends was negative $141.6 million at December 31, 2013 and January 1, 2014. FTBNA applied for and received approval from the OCC to declare and pay a common dividend to the parent company in the amount of $100.0 million in 2012 and $180.0 million in 2013. During 2013, FTBNA applied for and received approval from the OCC to declare and pay dividends on its preferred stock quarterly. Additionally, FTBNA has requested approval from the OCC to declare and pay dividends on its preferred stock outstanding payable in April 2014.
	The payment of cash dividends by FHN and FTBNA may also be affected or limited by other factors, such as the requirement to maintain adequate capital above regulatory guidelines and debt covenants. Furthermore, the Federal Reserve and the OCC have issued policy statements generally requiring insured banks and bank holding companies only to pay dividends out of current operating earnings. Consequently, the decision of whether FHN will pay future dividends and the amount of dividends will be affected by current operating results.
	Restrictions on intercompany transactions. Under current Federal banking law, banking subsidiaries may not extend credit to any affiliate including the parent company and certain financial subsidiaries in excess of 10 percent of the bank's capital stock and surplus, as defined, or $345.1 million, on December 31, 2013. The equity investment, including retained earnings, in certain of a bank's financial subsidiaries is also treated as a covered transaction. The parent company had covered transactions of $.5 million from FTBNA and the bank's financial subsidiary, FTN Financial Securities Corp., had a total equity investment from FTBNA of $366.9 million on December 31, 2013. Since the equity investment FTBNA has in FTN Financial Securities Corp. exceeds the 10 percent per affiliate limit, FTBNA cannot engage in any additional covered transactions with this affiliate and the banking regulators could require FTBNA to reduce its equity investment so that it is within the limit. In addition, the aggregate amount of covered transactions with all affiliates, as defined, is limited to 20 percent of the bank's capital stock and surplus, as defined, or $690.2 million, on December 31, 2013. FTBNA's total covered transactions with all affiliates including the parent company on December 31, 2013 were $367.5 million.

	A deferred tax asset (“DTA”) or deferred tax liability (“DTL”) is recognized for the tax consequences of temporary differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. The tax consequence is calculated by applying enacted statutory tax rates, applicable to future years, to these temporary differences. In order to support the recognition of the DTA, FHN's management must believe that the realization of the DTA is more likely than not. FHN evaluates the likelihood of realization of the DTA based on both positive and negative evidence available at the time, including (as appropriate) scheduled reversals of DTLs, projected future taxable income, tax planning strategies, and recent financial performance. Realization is dependent on generating sufficient taxable income prior to the expiration of the carryforwards attributable to the DTA. In projecting future taxable income, FHN incorporates assumptions including the estimated amount of future state and federal pretax operating income, the reversal of temporary differences, and the implementation of feasible and prudent tax planning strategies. These assumptions require significant judgment about the forecasts of future taxable income and are consistent with the plans and estimates used to manage the underlying business.
	As of December 31, 2013, the gross DTA is $463.5 million. The gross DTL is $130.0 million as of December 31, 2013. Management has assessed the ability to realize the gross DTA based on positive and negative evidence and on the basis of this evaluation, a valuation allowance of $57.8 million was recorded as of December 31, 2013. The valuation allowance is attributable to certain state net operating loss ("NOL") carryforwards of $5.9 million and to capital loss carryforwards of $51.9 million. Management believes it is more likely than not that the benefit of the capital loss carryover to 2014 will not be realized because there is uncertainty as to whether FHN will generate capital gains over the five year carryforward period. The DTA after the valuation allowance is $405.7 million as of December 31, 2013. Although realization is not assured, FHN believes that its ability to realize the net DTA is more likely than not.
	Temporary differences which gave rise to deferred tax assets and deferred tax liabilities on December 31, 2013 and 2012 were as follows:

The total unrecognized tax benefits ("UTB") at December 31, 2013 and December 31, 2012, was $6.6 million and $17.6 million, respectively. FHN is currently in audit in several jurisdictions. It is reasonably possible that the UTB could decrease by $4.1 million during 2014 if audits are completed and settled and if the applicable statutes of limitations expire as scheduled. FHN recognizes interest accrued and penalties related to UTB within income tax expense. FHN had approximately $2.0 million and $4.5 million accrued for the payment of interest as of December 31, 2013 and December 31, 2012, respectively.

Contingencies And Other Disclosures	'
	Note 18 – Contingencies and Other Disclosures
	Contingencies
	General
	Contingent liabilities arise in the ordinary course of business. Often they are related to lawsuits, arbitration, mediation, and other forms of litigation. Various litigation matters are threatened or pending against FHN and its subsidiaries. Also, FHN at times receives requests for information, subpoenas, or other inquiries from federal, state, and local regulators, from other government authorities, and from other parties concerning various matters relating to FHN's current or former lines of business. Certain matters of that sort are pending at this time, and FHN is cooperating in those matters. In view of the inherent difficulty of predicting the outcome of these matters, particularly where the claimants seek very large or indeterminate damages, or where the cases present novel legal theories or involve a large number of parties, or where claims or other actions may be possible but have not been brought, FHN cannot reasonably determine what the eventual outcome of the pending matters will be, what the timing of the ultimate resolution of these matters may be, or what the eventual loss or impact related to each matter may be. FHN establishes loss contingency liabilities for litigation matters when loss is both probable and reasonably estimable as prescribed by applicable financial accounting guidance. A liability generally is not established when loss for a matter either is not probable or its amount is not reasonably estimable. If loss for a matter is probable and a range of possible loss outcomes is the best estimate available, accounting guidance requires a liability to be established at the low end of the range. See "Contingency Accruals" within Note 1 - Summary of Significant Accounting Policies for additional information.
	In addition, disclosure of a range of reasonably possible loss associated with contingent liabilities, as prescribed by applicable financial accounting guidance, is provided as to those matters where there is more than a remote chance of an estimable, material loss outcome for FHN in excess of currently established loss liabilities. Based on current knowledge, and after consultation with counsel, management is of the opinion that loss contingencies related to such threatened or pending litigation matters should not have a material adverse effect on the consolidated financial condition of FHN, but may be material to FHN's operating results for any particular reporting period depending, in part, on the results from that period.
	Litigation – Gain Contingency
	The Chapter 11 Liquidation Trustee (the “Trustee”) of Sentinel Management Group, Inc. (“Sentinel”) filed complaints against two subsidiaries, First Tennessee Bank National Association ("FTBNA") and FTN Financial Securities Corp. (“FTN”), and two former FTN employees. The Trustee's claims related to Sentinel's purchases of Preferred Term Securities Limited (“PreTSL”) products and other securities from FTN and/or the FTN Financial Capital Markets division of FTBNA from March 2005 to August 2007. In July 2011, the parties reached an agreement to settle the dispute. Under the terms of the settlement the Trustee received a total of $38.5 million. After considering the terms of the settlement, FHN recognized a pre-tax expense of $36.7 million during second quarter 2011 related to the settlement. FHN believes that certain insurance policies provide coverage for these losses and related litigation costs, subject to policy limits and applicable deductibles. The insurers have denied coverage. FHN has brought suit against the insurers to enforce the policies under Tennessee law. The suit is in U.S. District Court for the Western District of Tennessee styled as First Horizon National Corporation, et al. v. Certain Underwriters at Lloyd's Syndicate Nos. 2987, et al., No. 2:11-cv-02608. In connection with this matter the previously recognized expense may be recouped in whole or in part. As to this matter, under applicable financial accounting guidance, FHN has determined that although material gain is not probable there is more than a slight chance of a material gain outcome for FHN. FHN cannot estimate the amount of possible gain that might result from this matter because of general uncertainties associated with unresolved legal proceedings and also due to significant uncertainties regarding: legal interpretation of the relevant contracts; potential remedies that might be available or awarded; and the incomplete status of the discovery process.
	Litigation – Loss Contingencies
	Set forth below are discussions of certain pending or threatened litigation matters. These material loss contingency matters generally fall into the following categories: (i) FHN has determined material loss to be probable and has established a material loss liability in accordance with applicable financial accounting guidance, other than matters reported as having been substantially settled or otherwise substantially resolved; (ii) FHN has determined material loss to be probable but is unable to determine an amount of material loss liability; or (iii) FHN has determined that material loss is not probable but is "reasonably possible" (as defined in applicable accounting guidance, there is more than a remote chance of a material loss outcome for FHN). In all litigation matters discussed, except as indicated, FHN has estimated a range of reasonably possible loss outcomes in excess of any currently established loss liabilities. In all litigation matters discussed, unless settled or resolved, FHN believes it has meritorious defenses and intends to pursue those defenses vigorously.
	FHN reassesses the liability for litigation matters each quarter as the matters progress. At December 31, 2013, the aggregate amount of liabilities established for the litigation loss contingency matters discussed below was $60.5 million. Only one pending matter discussed under the heading "First Horizon Branded Mortgage Securitization Litigation Matters" below, the FHFA suit, is among those matters for which a liability has been established. The liabilities discussed in this paragraph are separate from those discussed under the heading "Established Repurchase Liability" below.
	In each potential loss contingency litigation matter discussed below, except as otherwise noted, there is a more than slight chance that each of the following outcomes will occur: the plaintiff will substantially prevail; the defense will substantially prevail; the plaintiff will prevail in part; or the matter will be settled by the parties. At December 31, 2013, FHN estimates that, for those litigation loss contingency matters discussed below as to which reasonably possible loss is estimable, reasonably possible losses in future periods in excess of currently established liabilities could aggregate in a range from zero to approximately $180 million. Of those matters discussed under the heading "First Horizon Branded Mortgage Securitization Litigation Matters," only the FHFA, Charles Schwab, Western & Southern, and FDIC (NY) suits are included in that range.
	Matters Included in Reasonably Possible Loss Range
	Debit Transaction Sequencing Litigation Matter. FTBNA is a defendant in a putative class action lawsuit concerning overdraft fees charged in connection with debit card transactions. A key claim is that the method used to order or sequence the transactions posted each day was improper. The case is styled as Hawkins v. First Tennessee Bank National Association, before the Circuit Court for Shelby County, Tennessee, Case No. CT-004085-11. The plaintiff seeks actual damages of at least $5 million, unspecified restitution of fees charged, and unspecified punitive damages, among other things. FHN's estimate of reasonably possible loss for this matter is subject to significant uncertainties regarding: whether a class will be certified and, if so, the definition of the class; claims as to which no dollar amount is specified; the potential remedies that might be available or awarded; the outcome of potentially dispositive early-stage motions such as motions to dismiss; and the incomplete status of the discovery process.
	RPL-Included First Horizon Branded Mortgage Securitization Litigation Matters. Several pending litigation matters are discussed under the heading "First Horizon Branded Mortgage Securitization Litigation Matters" below. For certain of those FHN has been able to estimate reasonably possible loss. Those estimable matters are the FHFA, Charles Schwab, Western & Southern, and FDIC (NY) cases. The estimates for those matters are included in the range of reasonably possible loss discussed above. The estimates are subject to significant uncertainties regarding: the dollar amount claimed; the potential remedies that might be available or awarded; the outcome of any settlement discussions; the outcome of potentially dispositive early stage motions such as motions to dismiss; the availability of significantly dispositive defenses such as statutes of limitations or repose; the identity and value of assets that FHN may be required to repurchase to the extent asset repurchase is sought; the incomplete status of the discovery process; and the lack of precedent claims.
	Matters Not Included in Reasonably Possible Loss Range
	RPL-Excluded First Horizon Branded Mortgage Securitization Litigation Matters. Several pending litigation matters are discussed under the heading "First Horizon Branded Mortgage Securitization Litigation Matters" below. For certain of those FHN has been able to estimate reasonably possible loss as mentioned in the preceding paragraph, and for others FHN has not. Those matters which currently are not estimable are the FDIC (AL) case and the FHLB of San Francisco, Metropolitan Life, Royal Park, and certain indemnity cases. FHN is unable to estimate a range of reasonably possible loss due to significant uncertainties regarding: claims as to which the claimant specifies no dollar amount; the potential remedies that might be available or awarded; the availability of significantly dispositive defenses such as statutes of limitations or repose; the outcome of potentially dispositive early-stage motions such as motions to dismiss; the identity and value of assets that FHN may be required to repurchase for those claims seeking asset repurchase; the non-started or incomplete status of the discovery process; the lack of a precise statement of damages; and lack of precedent claims.
	Inquiry Regarding FHA-Insured Loans. Since second quarter 2012 FHN has been cooperating with the U.S. Department of Justice (“DOJ”) and the Office of the Inspector General for the Department of Housing and Urban Development ("HUD") in a civil investigation regarding compliance with requirements relating to certain FHA-insured loans. During second quarter 2013 DOJ and HUD provided FHN with preliminary findings of the investigation, which focused on a small sample of loans and remain incomplete. No demand or claim has been made of FHN. The investigation could lead to a demand under the federal False Claims Act and the federal Financial Institutions Reform, Recovery, and Enforcement Act of 1989, which allow treble and other special damages substantially in excess of actual losses. Currently FHN is not able to predict the eventual outcome of this matter. FHN has established no liability for this matter and is not able to estimate a range of reasonably possible loss due to significant uncertainties regarding: the absence of any specific demand or claim; the potential remedies, including any amount of enhanced damages, that might be available or awarded; the availability of significantly dispositive defenses; FHN's lack of information that would enable FHN to assess performance concerning its FHA-insured originations, many of which FHN does not service; and the small number of reported precedent claims and resolutions (involving other parties) combined with a lack of underlying data connected with those resolutions.
	The investigation has focused on loans originated by FHN on or after January 1, 2006. FHA-insured originations from January 1, 2006 through the August 31, 2008 divestiture of FHN's national mortgage platform totaled 47,817 loans with an aggregate original principal balance of $8.2 billion. The amount of FHA-insured originations each year has declined substantially following the divestiture.
	First Horizon Branded Mortgage Securitization Litigation Matters
	Prior to September 2008 FHN originated and sold home loan products through various channels and conducted its servicing business under the First Horizon Home Loans and First Tennessee Mortgage Servicing brands. Those sales channels included the securitization of loans into pools held by trustees and the sale of the resulting securities, sometimes called “certificates,” to investors. These activities are discussed in more detail below under the heading “Legacy Home Loan Sales and Servicing.”
	At the time this report is filed, FHN, along with multiple defendants, is defending several lawsuits brought by investors which claim that the offering documents under which certificates relating to First Horizon branded securitizations ("FH proprietary securitizations") were sold to them were materially deficient. The plaintiffs and venues of these suits are: (1) the Federal Housing Finance Agency (“FHFA”), as conservator for Fannie Mae and Freddie Mac, in U.S. District Court for the Southern District of New York (Case No. 11-cv-6193 (PGG)); (2) Charles Schwab Corp. in the Superior Court of San Francisco, California (Case No. 10-501610); (3) Western & Southern Life Insurance Co, among others, in the Court of Common Pleas, Hamilton County, Ohio (Case No. A1105352); (4) Federal Deposit Insurance Corporation ("FDIC") as receiver for Colonial Bank, in the U.S. District Court for the Middle District of Alabama (Case No. CV-12-791-WKW-WC); and (5) FDIC as a receiver for Colonial Bank, in the U.S. District Court for the Southern District of New York (Case No. 12 Civ. 6166 (LLS)(MHD)). The plaintiffs in the pending suits claim to have purchased certificates in a number of separate FH proprietary securitizations and demand that FHN repurchase their investments, or answer in damages or rescission, among other remedies sought.
	In some of the pending suits underwriters are co-defendants and have demanded, under provisions in the applicable underwriting agreements, that FHN indemnify them for their expenses and any losses they may incur. In addition, FHN has received indemnity demands from underwriters in certain other suits as to which investors claim to have purchased senior certificates in FH proprietary securitizations. FHN has not been named a defendant in these suits, which FHN is defending indirectly as indemnitor. The plaintiffs and venues of these other suits are: (6) FHLB of San Francisco, in the Superior Court of San Francisco County, California (Case No. CGC-10-497840); (7) Metropolitan Life Insurance Co., in the Supreme Court of New York County, New York (No. 651360-2012); and (8) Royal Park Invs. SA/NV, in the Supreme Court of New York County, New York (No. 652607-2012).
	Details concerning the original purchase amounts and ending balances of the investments at issue in these pending suits, as to which FHN is a named defendant or as to which FHN has an agreement to indemnify an underwriter defendant, are set forth below. Information about the performance of the FH proprietary securitizations related to these suits is available in monthly reports published by the trustee for the securitization trusts. FHN believes that certain plaintiffs did not purchase the entire certificate in the securitizations in which they invested. Reporting by the trustee is at a certificate level and, as a result, ending certificate balances in the following table were adjusted to reflect FHN's estimate of the ending balance of each partial certificate purchased by these plaintiffs. Plaintiffs in the pending lawsuits claim to have purchased a total of $1.1 billion of certificates and the purchase prices of the certificates subject to the indemnification requests total $331.4 million. “Senior” and “Junior” refer to the ranking of the investments in broad terms; in most cases the securitization provided for sub-classifications within the Senior or Junior groups.

	The amounts shown in the table which are the subject of the FHFA litigation includes $230,020 of the Senior Alt-A loans from 2006 and $643,751 of the Senior Alt-A loans from 2005.
	If FHN were to repurchase certificates, it would recognize as a loss the difference between the amount paid (adjusted for any related litigation liability previously established) and the fair value of the certificates at that time.
	The ending certificate balance of the investments which are the subject of the FHFA lawsuit was $311.6 million as reported on the December 25, 2013, trust statements, with approximately 90 percent of the remaining balances performing. Cumulative losses on the FHFA investments which are the subject of the lawsuit, as reported on the trust statements, represent approximately 7 percent of the original principal amount underlying the certificates purchased. The total ending certificate balance of the investments which are the subject of the remaining lawsuits was $223.2 million as reported on the December 25, 2013, trust statements, with approximately 80 percent of the remaining balances performing. Cumulative losses on the investments which are the subject of the remaining lawsuits, as reported on the trust statements, represent approximately 8 percent of the original principal amount underlying the certificates purchased. Ending certificate balances reflect the remaining principal balance on the certificates, after the monthly principal and interest distributions and after reduction for applicable cumulative and current realized losses. Recognized cumulative losses may not take into account all outstanding principal and interest amounts advanced by the servicer due to nonpayment by the borrowers; reimbursement of those advances to the servicer may increase cumulative losses. Losses often are reported by the trustee based on each certificate within a pool or group, which limits FHN's ability to ascertain losses at the individual investor level.
	As discussed under “Legacy Home Loan Sales and Servicing,” similar claims may be pursued by other investors, and loan repurchase, make-whole, or indemnity claims may be pursued by securitization trustees or other parties to transactions seeking indemnity. At December 31, 2013, except for the FHFA case, FHN had not recognized a liability for exposure for investment rescission or damages arising from the foregoing or other potential claims by investors that the offering documents under which the loans were securitized were materially deficient, nor for exposure for repurchase of loans arising from potential claims that FHN breached its representations and warranties made in FH proprietary securitizations at closing.
	Contract Claim Settlement Process – Mortgage Repurchase Pipeline
	For several years FHN has received claims from government sponsored enterprises ("GSEs"), other government agencies, mortgage insurers, and others that FHN breached certain representations and warranties made in connection with whole-loan sales prior to September 2008. Generally such claims request or otherwise demand that FHN repurchase the loans or otherwise make the purchaser whole. FHN analyzes these claims using a pipeline approach. FHN reviews each claim in the pipeline and either offers to satisfy the claim or rejects the claim by asking the claimant to rescind it. FHN has established a material loss liability for probable incurred losses related to repurchase obligations for breaches of selling representations and warranties. Estimation for losses associated with repurchase obligations includes both trends observed in the pipeline and additional information that encompasses a broader population of loans. See the discussion under “Estimated Repurchase Liability.” As of December 31, 2013, none of these claims had become active litigation. These matters and the associated reserving methodologies are discussed under “Legacy Home Loan Sales and Servicing."
	Legacy Home Loan Sales and Servicing
	Overview
	Prior to September 2008, as a means to provide liquidity for its legacy mortgage banking business, FHN originated loans through its legacy mortgage business, primarily first lien home loans, with the intention of selling them. Some government-insured and government-guaranteed loans were originated with credit recourse retained by FHN and some other mortgages were originated to be held, but predominantly mortgage loans were intended to be sold without recourse for credit default. Sales typically were effected either as non-recourse whole-loan sales or through non-recourse proprietary securitizations. Conventional conforming single-family residential mortgage loans were sold predominately to two GSEs - the Federal National Mortgage Association ("Fannie Mae," "Fannie," or "FNMA") and the Federal Home Loan Mortgage Corporation ("Freddie Mac," "Freddie," or "FHLMC"). Federally insured or guaranteed whole-loans were pooled, and payments to investors were guaranteed through the Government National Mortgage Association ("Ginnie Mae," "Ginnie," or "GNMA"). Collectively, Fannie Mae, Freddie Mac, and Ginnie Mae are referred to as the "Agencies." Many mortgage loan originations, especially those "nonconforming" mortgage loans that did not meet criteria for whole-loan sales to the GSEs, or insurance through Ginnie Mae, were sold to investors, or certificate-holders, predominantly through proprietary securitizations but also, to a lesser extent, through whole-loan sales to private non-Agency purchasers. In addition, FHN originated with the intent to sell and sold HELOCs and second lien mortgages through whole-loan sales to private purchasers and, to a lesser extent, through proprietary securitizations.
	Regarding these past first lien loan sale activities, FHN has exposure to potential loss primarily through two avenues. First, purchasers of these mortgage loans may request that FHN repurchase loans or make the purchaser whole for economic losses incurred if it is determined that FHN violated certain contractual representations and warranties made at the time of these sales. Contractual representations and warranties differ based on deal structure and counterparty. For whole-loan sales, a claimant generally would be the purchaser. For securitizations, a repurchase claimant generally would be a trustee. Second, investors in securitizations may attempt to achieve rescission of their investments or damages through litigation by claiming that the applicable offering documents were materially deficient. In addition, augmenting these avenues: the trustee for the securitized loans may seek repurchase of loans under contractual remedies; some of the loans that were sold or securitized were insured and the insurance carrier may seek repurchase or make-whole remedies by claiming that FHN violated certain contractual representations and warranties made in connection with the insurance contract; some of the loans sold to non-Agency whole-loan purchasers were included in securitizations of the purchasers, and the purchasers may seek repurchase or indemnification for losses and expenses caused by such a violation by FHN; and, some loans were originated under government insurance or guarantee programs and the government agency, or a person acting on its behalf, may seek contractual or statutory remedies based on claimed violations of the requirements of the respective program. In some cases FHN retained the servicing of the loans sold or securitized and so had substantial visibility into the status of the loans; in many cases FHN did not retain servicing and has had very limited or no such direct visibility. Moreover, since 2008 FHN has sold significant amounts of servicing rights in several transactions. Under the most recent servicing sale agreement FHN sold, in late 2013 and early 2014, substantially all its remaining legacy servicing.
	From 2005 through 2008, FHN originated and sold $69.5 billion of mortgage loans to the Agencies without recourse which includes $57.6 billion of loans sold to GSEs and $11.9 billion of loans guaranteed by Ginnie Mae. Although additional GSE sales occurred in earlier years, a substantial majority of GSE repurchase requests have come from that period. While substantially all of the losses for repurchase obligations related to sales to GSEs have been from vintages originated during 2005 through 2008, the definitive resolution agreements ("DRAs") discussed below also include originations from 2000 through 2004. In addition, for many years ending in 2007, FHN securitized mortgage loans without recourse in First Horizon branded proprietary transactions. From 2005 through 2007, FHN securitized $26.7 billion of mortgage loans under the First Horizon ("FH") brand.
	On August 31, 2008 FHN sold its national mortgage origination and servicing platforms along with a portion of its servicing assets and obligations. This is sometimes referred to as the “2008 sale,” the “2008 divestiture,” the “platform sale,” or other similar terms. FHN contracted to have its remaining servicing obligations sub-serviced. Since the platform sale FHN has sold substantially all remaining servicing assets and obligations, as mentioned above.
	Loans Sold With Full or Limited Recourse
	Although not a substantial part of FHN's former business, FHN sold certain Agency mortgage loans with full recourse under agreements to repurchase the loans upon default. Loans sold with full recourse generally include mortgage loans sold to investors in the secondary market which are uninsurable under government mortgage loan programs due to issues associated with underwriting activities, documentation, or other concerns. For mortgage insured single-family residential loans, in the event of borrower nonperformance, FHN would assume losses to the extent they exceed the value of the collateral and private mortgage insurance (“MI”), the Federal Housing Administration ("FHA") insurance, or the Veteran's Administration (“VA”) guaranty. On December 31, 2013 and 2012, the current UPB of single-family residential loans that were sold on a full recourse basis with servicing retained was $.5 million and $36.1 million, respectively.
	Loans sold with limited recourse include loans sold under government insured or guaranteed mortgage loan programs including the FHA and VA. FHN may absorb losses due to uncollected interest and foreclosure costs but has limited risk of credit losses in the event of foreclosure of the mortgage loan sold. Generally, the amount of recourse liability in the event of foreclosure is determined based upon the respective government program and/or the sale or disposal of the foreclosed property collateralizing the mortgage loan. Another instance of limited recourse is the VA/No bid. In this case, the VA guarantee is limited and FHN may be required to fund any deficiency in excess of the VA guarantee if the loan goes to foreclosure.
	FHN also has potential loss exposure from claims that FHN violated FHA or VA requirements related to the origination of the loans and insurance or guarantee claims filed related to the loans. Additional information concerning a pending investigation related to FHA-insured lending is provided in "Inquiry Regarding FHA-Insured Loans" above.
	Unless otherwise noted, the remaining discussion under this section, “Legacy Home Loan Sales and Servicing,” excludes information concerning full or limited recourse loan sales.
	Agency Whole-loan Sales
	Substantially all of the conventional, conforming mortgage loans originated by FHN were sold to the GSEs. Each agency has specific guidelines and criteria for originators and servicers of loans backing their respective securities, and the risk of credit loss with regard to the principal amount of the loans sold was generally transferred to the GSEs upon sale, or resides with the insuring government agency if the loans were guaranteed through Ginnie.
	Generally these loans were sold without recourse for credit loss. However, if it is determined that the loans sold were in breach of representations or warranties required by the Agency and made by FHN at the time of sale, FHN has obligations to either repurchase the loan for the UPB or make the purchaser whole for the economic loss incurred by the purchaser of such loan. Such representations and warranties required by the Agencies typically include those made regarding the existence and sufficiency of file documentation and the absence of fraud by borrowers or other third parties such as appraisers in connection with obtaining the loan. A substantial amount of FHN's existing repurchase obligations from outstanding requests relate to conforming conventional mortgage loans that were sold to the GSEs. Since the mortgage platform sale in 2008 through December 31, 2013, Agencies have accounted for the vast majority of repurchase/make-whole claims received.
	GSE Settlement Efforts
	In the fourth quarter of 2013 FHN entered into a DRA with Fannie Mae, and in the first quarter of 2014 FHN entered into a DRA with Freddie Mac, in each case resolving certain legacy selling representation and warranty repurchase obligations associated with loans originated from 2000 to 2008 excluding certain loans FHN no longer serviced at the time of the DRA. Under each DRA, FHN remains responsible for repurchase obligations related to certain excluded defects (such as title defects and violations of the GSE's Charter Act) and FHN continues to have obligations related to mortgage insurance rescissions, cancellations and denials.  With respect to loans where there has been a prior bulk sale of servicing, FHN is not responsible for mortgage insurance cancellations and denials to the extent attributable to the acts of the current servicer.
	The repurchase liability FHN has recorded as of December 31, 2013 contemplates, among other things, each DRA, estimates of FHN's repurchase exposure related to loans excluded from the DRAs, and estimates of FHN's repurchase exposure related to certain other loan sales. See “Established Repurchase Liability” below for additional information.
	First Horizon Branded Proprietary Mortgage Securitizations
	From 2005 through 2007 FHN originated and sold certain non-agency, nonconforming mortgage loans, consisting of Jumbo and Alternative-A (“Alt A”) first lien mortgage loans, to private investors through 80 proprietary securitization trusts under the FH brand. Securitized loans generally were sold indirectly to investors as interests, commonly known as certificates, in trusts. The certificates were sold to a variety of investors, including GSEs in some cases, through securities offerings under a prospectus or other offering documents. In most cases, the certificates were tiered into different risk classes, with junior classes exposed to trust losses first and senior classes exposed only after junior classes were exhausted. Through third quarter 2013, FHN continued to service substantially all of the remaining loans sold through FH proprietary securitizations. In third quarter FHN contracted to sell substantially all such servicing rights and obligations, with transfers occurring largely in fourth quarter 2013 and first quarter 2014. As of December 31, 2013, the remaining UPB in active FH proprietary securitizations from 2005 through 2007 was $7.1 billion consisting of $4.9 billion Alt-A mortgage loans and $2.2 billion Jumbo mortgage loans. Representations and warranties were made to the securitization trustee for the benefit of investors. As such, FHN has exposure to the trustee for repurchase of loans arising from claims that FHN breached its representations and warranties made at closing, and exposure to investors for investment rescission or damages arising from claims by investors that the offering documents under which the loans were securitized were materially deficient. As of December 31, 2013, the repurchase request pipeline contained no repurchase requests related to FH proprietary first lien securitizations based on breaches of representations and warranties.
	Unlike loans sold to GSEs, contractual representations and warranties for FH proprietary first lien securitizations do not include specific representations regarding the absence of other-party fraud or negligence in the underwriting or origination of the mortgage loans. Securitization documents typically provide the investors with a right to request that the trustee investigate and initiate repurchase of a mortgage loan if FHN breached certain representations and warranties made at the time the securitization closed and such breach materially and adversely affects the interests of the investors in such mortgage loan. The securitization documents do not require the trustee to make an investigation into the facts or matters stated in any investor request or notice unless requested in writing to do so by the holders of certificates evidencing not less than 25 percent of the voting rights allocated to each class of certificates. The certificate holders also may be required to indemnify the trustee for its costs related to investigations made in connection with repurchase actions. FHN has no knowledge of any investor requests to the trustee of an FH proprietary securitization to investigate mortgage loans for possible breach of representations and warranties. GSEs were among the purchasers of certificates in FH proprietary securitizations. As such, they are entitled to the benefits of the same representations and warranties as other investors. However, the GSEs, acting through their conservator under federal law, are permitted to undertake, independently of other investors, reviews of FHN's mortgage loan origination and servicing files. Such reviews are commenced using a subpoena process. If, because of such reviews, the GSEs determine there has been a breach of a representation or warranty that has had a material and adverse effect on the interests of the investors in any mortgage loan, the GSEs may attempt to persuade or compel enforcement of a repurchase obligation against FHN by the securitization trustee. Certain other government entities have asserted a similar right of review not generally available to other investors. As discussed in more detail below, FHN has received several such subpoenas.
	In addition, the FH proprietary securitization trustee generally may initiate a loan review, without prior official action by investors, for the purpose of determining compliance with applicable representations and warranties with respect to any or all of the active FH proprietary securitizations. If non-compliance is discovered, the trustee may seek repurchase or other relief. At December 31, 2013, FHN's trustee had made no claims against FHN and no litigation by the trustee was pending against FHN. Accordingly, FHN is not able to estimate any liability for this risk. FHN similarly is not able to estimate a range of reasonably possible losses associated with this risk, and no such amounts are included in the aggregate range discussed above. Those inabilities are due to significant uncertainties regarding: the absence of claims made; the nature and outcome of any claims process or related settlement discussions if pursued; the outcome of litigation if litigation is pursued; the identity and value of assets that FHN may be required to repurchase to the extent asset repurchase is sought; and the lack of precedent claims.
Also unlike loans sold to the GSEs through non-recourse whole-loan sales, interests in securitized loans were sold as securities under prospectuses or other offering documents subject to the disclosure requirements of applicable federal and state securities laws. As an alternative to pursuing a claim for breach of representations and warranties through the trustee as mentioned above, investors could pursue (and in certain cases mentioned below, are pursuing) a claim alleging that the prospectus or other disclosure documents were deficient by containing materially false or misleading information or by omitting material information. Claims for such disclosure deficiencies typically could be brought under applicable federal or state securities statutes, and the statutory remedies typically could include rescission of the investment or monetary damages measured in relation to the original investment made. Any such statutory claim would be subject to applicable limitation periods and other statutory defenses. If a plaintiff properly made and proved its allegations, the plaintiff might attempt to claim that damages could include loss of market value on the investment even if there were little or no credit loss in the underlying loans. Claims based on alleged disclosure deficiencies also could be brought as traditional fraud or negligence claims with a wider scope of damages possible. Each investor could bring such a claim individually, without acting through the trustee to pursue a claim for breach of representations and warranties, and investors could attempt joint claims or attempt to pursue claims on a class-action basis. Claims of this sort are likely to be resolved in a litigation context in most cases, unlike the GSE repurchase experience to date. The analysis of loss content and establishment of appropriate liabilities in those cases would follow principles and practices associated with litigation matters, including an analysis of available procedural and substantive defenses in each particular case, a determination of whether material loss is probable, and (if so) an estimation of the amount of ultimate loss, if any can be estimated. FHN expects most litigation claims to take much longer to resolve than GSE repurchase requests typically have taken.
Monoline insurance was a form of credit enhancement provided to a securitization by an insurer not affiliated with FHN. Subject to the terms and conditions of the policy, the insurer guaranteed payments of accrued interest and principal due to the investors. None of the FH proprietary first lien securitizations involved the use of monoline insurance for the benefit of all classes of security holders. In certain limited situations, insurance was provided for a specific senior retail class of holders within an individual securitization. The only insured certificate more recent than 2004 is from 2005 and covered $25.0 million of original certificate balance. The trustee statement dated December 25, 2013, reported to FHN that the remaining outstanding certificate balance for the class was $23.5 million. FHN understands that some monoline insurers have commenced lawsuits against others in the industry seeking to rescind policies of this sort due to alleged misrepresentations as to the quality of the loan portfolio insured. FHN has not received notice of a lawsuit from the monoline insurers of the senior retail level class.
Other First Horizon Branded Proprietary Securitizations
FHN originated and sold home equity lines and second lien loans through certain FH proprietary securitization trusts, most of which related to HELOC loans. As of December 31, 2013, only three of those securitizations, all HELOC, remain active; the rest have been retired as a result of clean-up calls exercised by FHN. Each remaining trust issued notes backed by these loans and publicly offered the asset-backed notes to investors pursuant to a prospectus. The Trustee statements dated December 25, 2013, reported that the cumulative original and current outstanding note balances of the remaining FH proprietary HELOC securitizations were $961.8 million and $296.5 million, respectively.
The loans in the FH HELOC securitization trusts are included on FHN's balance sheet in accordance with GAAP either as consolidated variable interest entities (“VIEs”) or because the securitization did not qualify for sale treatment under GAAP. These loans and the associated credit risk are reflected in FHN's consolidated financial statements.
The asset-backed notes issued in the FH proprietary HELOC securitizations were “wrapped” by monoline insurers. FHN understands that some monoline insurers have commenced lawsuits against other originators of asset-backed securities seeking to cancel policies of this sort due to alleged misrepresentations as to the quality of the loan portfolio insured. FHN has not received notice from a monoline insurer of any such lawsuit. The monoline insurers also have certain contractual rights to pursue repurchase and indemnification. In response to unreimbursed insurance draws resulting from insufficient remittances to investors, three monoline insurers of certain FH proprietary HELOC securitizations have commenced reviews of these HELOC securitizations and certain underlying loan files, underwriting guidelines, and payment histories. Repurchase requests have been received; in some cases requests have been rescinded and in others repurchases have been made. Because the underlying loans and their associated loss content are recorded on FHN's balance sheet, FHN reviews the portfolio each quarter for inherent loss and has established reserves for loss content. For that reason, FHN does not include these requests in the repurchase pipeline reported for first lien mortgages, and FHN believes that any ultimate cash payouts related to these loans are unlikely to have any material impact upon FHN's financial results as such payouts would be reflected as reductions to the existing balance of restricted or secured term borrowings. The monoline insurer for two of the HELOC securitizations has requested that, due to the default caused by the unreimbursed insurance draws, the insurer and FHN should explore collapsing the trusts and purchasing the underlying collateral as a remedy. If that action were taken FHN could incur some incremental loss based upon the nature of the collateral and the amounts required to be paid to collapse the trusts.
Additionally, advances made by monoline insurers for the benefit of security holders have been recognized within restricted or secured term borrowings in the Consolidated Statements of Condition. This recognition practice is used because the insurers have a higher priority to certain cash flows from the securitization trusts than FHN.
Other Whole-loan Sales
FHN has sold first lien mortgages without recourse through whole-loan sales to non-Agency purchasers. FHN made contractual representations and warranties to the purchasers generally similar to those made to Agency purchasers. As of December 31, 2013, 16 percent of repurchase/make-whole claims in the pipeline relate to private whole loan sales. These claims are included in FHN's liability methodology and the assessment of the adequacy of the repurchase and foreclosure liability.
Many of these loans were included by the purchasers in non-FH securitizations. FHN's contractual representations and warranties to these loan purchasers generally included indemnity covenants for losses and expenses applicable to the securitization caused by FHN's breach. Currently the following categories of actions are pending which involve FHN and non-Agency whole-loan sales: (i) FHN has received indemnification requests from purchasers of loans or their assignees in cases where FHN is not a defendant; (ii) FHN has received subpoenas seeking loan reviews in cases where FHN is not a defendant; (iii) FHN has received repurchase demands from purchasers or their assignees; and (iv) FHN is a defendant in two legal actions involving FHN-originated loans. In some cases the loans to be reviewed, or which otherwise are at issue, have not been identified specifically. Assignees can include securitizers or securitization trustees, among others. A loan is included in the repurchase pipeline only when an identifiable demand for repurchase has been made outside of active litigation.
Other Government Entity Loan Reviews
Certain government entities acting on behalf of several purchasers of FH proprietary and other securitizations have subpoenaed information from FHN and others. In 2009 FHN was subpoenaed by the federal regulator of credit unions, the National Credit Union Administration ("NCUA"), related to FH proprietary securitization investments by certain federal credit unions. There has been little communication with FHN associated with this matter since 2010. FHN has been subpoenaed by the FHFA acting as conservator for Fannie Mae and Freddie Mac related to securitization investments by those institutions. In addition, the FHLB of San Francisco and FHLB of Atlanta have subpoenaed FHN for purposes of a loan origination review related to certain of their securitization investments. Collectively, the NCUA, FHFA, and FHLB subpoenas seek information concerning a number of FH proprietary first lien securitizations and a FH proprietary HELOC securitization during 2005 and 2006. In addition, the FDIC, acting on behalf of certain failed banks, has also subpoenaed FHN related to FH proprietary securitization investments by those institutions.
The FDIC, FHFA and FHLB of San Francisco subpoenas also concern loans sold by FHN to non-Agency purchasers on a whole-loan basis which were included by those purchasers in non-FH securitizations. That lending activity is discussed above under "Other Whole-loan Sales." In addition, the FHLB of Seattle has subpoenaed FHN in connection with FHN-originated loans that were included in non-FH securitizations. The FDIC subpoena fails to identify the specific investments made by the failed banks. Other than the dollar amounts of those investments which are the subject of the FDIC's active litigation as receiver for Colonial Bank, FHN has limited information regarding at least some of the loans under review or the dollar amounts invested in relation to the FDIC, FHFA, and FHLB subpoenas. The FDIC subpoenas overlap partially, and the FHFA subpoenas overlap substantially, with the ongoing litigation matters mentioned above under "Litigation - Loss Contingencies."
The subpoenas discussed above relate to ongoing reviews which ultimately could result in claims against FHN. The original and current (as of December 25, 2013 trust statements) combined first lien certificate balances of the related FH proprietary securitizations in which the credit unions invested were $321.6 million and $110.6 million, respectively. The original and current (as of December 25, 2013 trust statements) HELOC certificate balances of the related FH proprietary HELOC securitization in which the credit unions invested was $299.8 million and $80.8 million. The original and current certificate balances of the FH proprietary securitizations in which the FHLB of San Francisco invested are $501.1 million and $151.0 million, respectively. The original and current certificate balances of the FH proprietary securitizations in which the FHLB of Atlanta invested are $56.1 million and $11.2 million, respectively. There are limitations as to FHN's knowledge of the amount of FH proprietary securitizations investments that are subject to the FDIC, FHFA and FHLB of San Francisco subpoenas. Since the reviews at this time are neither repurchase claims nor litigation, the associated loans are not considered part of the repurchase pipeline.
Private Mortgage Insurance
MI was required by GSE rules for certain of the loans sold to GSEs and was also provided for certain of the loans that were securitized. MI generally was provided for the first lien loans sold or securitized having a loan-to-value ratio at origination of greater than 80 percent. Although unresolved MI cancellation notices related to GSE-owned loans are not formal repurchase requests, FHN includes these in the active repurchase request pipeline. FHN tracks and monitors MI cancellation notices received and considers the amount of loans sold to GSEs where MI coverage has ultimately been lost when assessing the overall adequacy of FHN's repurchase liability. As of December 31, 2013 and 2012, $478.0 million and $436.0 million, respectively, of loans sold or securitized have lost MI coverage.
Established Repurchase Liability
In fourth quarter, FHN entered into a DRA, discussed above in “GSE Settlement Efforts,” to resolve certain selling representation and warranty repurchase obligations with Fannie Mae. In connection with the DRA, FHN received additional information which was used to estimate repurchase liability levels at September 30, 2013 and at year-end. Compared with earlier periods, that information encompassed a broader population of loans including older vintages and expanded selection criteria from the remaining loan populations. The new information added the origination vintages of 2000 through 2004, expanded the scope of selections, and included estimates for losses from loans in early stage delinquency, modifications, and loans determined to have a higher probability of default. In February 2014, FHN entered into a DRA, also discussed above, with Freddie Mac. In connection with that DRA FHN also received certain additional information which FHN used to estimate repurchase liability levels at year-end. FHN used all available information to estimate losses related to potential repurchase obligations not included in the DRAs including future MI rescissions, prior bulk servicing sales where FHN is no longer the directly responsible party but still has repurchase obligations, and obligations related to certain other loan sales. Additionally, FHN continues to monitor claims included in the active pipeline, historical repurchase rates, and loss severities.
Based on currently available information and experience to date, FHN has evaluated its exposure under these obligations and accordingly has reserved for losses of $165.8 million and $234.1 million as of December 31, 2013 and 2012, respectively, including a smaller amount related to equity-lending junior lien loan sales. Accrued liabilities for FHN's estimate of these obligations are reflected in Other liabilities on the Consolidated Statements of Condition. Charges to increase the liability are included within Repurchase and foreclosure provision on the Consolidated Statements of Income. The estimates are based upon currently available information and fact patterns that exist as of the balance sheet dates and could be subject to future changes. Changes to any one of these factors could significantly impact the estimate of FHN's liability.
Servicing and Foreclosure Practices
Through third quarter 2013, FHN serviced a predominately first lien mortgage loan portfolio with an unpaid principal balance of approximately $15 billion as of September 30, 2013. In fourth quarter, sales of substantially all remaining servicing commenced, resulting in the loan portfolio serviced by FHN at December 31, 2013 having an unpaid principal balance of approximately $10 billion.
A substantial portion of the first lien portfolio was serviced through a subservicer. FHN's national mortgage and servicing platforms were sold in August 2008 and the related servicing activities, including foreclosure and loss mitigation practices, of the then-remaining portion of FHN's mortgage servicing portfolio was outsourced through a three year subservicing arrangement (the “2008 subservicing agreement”) with the platform buyer (the “2008 subservicer”). The 2008 subservicing agreement expired in 2011 when FHN entered into a replacement agreement with a new subservicer (the “2011 subservicer”). In third quarter 2013 FHN contracted to sell a substantial majority of its remaining servicing obligations and servicing assets (including advances) to the 2011 subservicer. The servicing is to be transferred to the buyer in stages, with substantial completion expected in first quarter 2014. Servicing still retained by FHN after year-end 2013 was subserviced by the 2011 subservicer.
The first lien portfolio is held primarily by private security holders and GSEs, with less significant portions held by other private investors. In connection with its servicing activities, FHN collected and remitted the principal and interest payments on the underlying loans for the account of the appropriate investor. In the event of delinquency or non-payment on a loan in a private or agency securitization: (1) the terms of the private securities agreements generally require the servicer, to continue to make monthly advances of principal and interest (“P&I”) to the trustee for the benefit of the investors; (2) the terms of the majority of the agency agreements may require the servicer to make advances of P&I, or in certain circumstances to repurchase the loan out of the trust pool; and (3) the servicer may be required to advance escrow and other payments. In the event advances are ultimately made by the servicer to satisfy these servicing obligations, these servicing advances are recoverable from: (a) the liquidation proceeds of the property securing the loan, in the case of private securitizations; (b) the proceeds of the foreclosure sale by the government agency, in the case of government agency-owned loans; and (c) in certain circumstances, mortgage payment pool funds. As of December 31, 2013 and 2012, FHN has recognized servicing advances of $261.8 million and $303.3 million, respectively. Servicing advances are included in Other assets on the Consolidated Statements of Condition. Those advances are part of the assets sold under the servicing sale agreement FHN entered into late in 2013; transfers under that agreement occurred partly in 2013 and partly in 2014.
FHN is subject to losses in its current and former loan servicing portfolio due to loan foreclosures. Foreclosure exposure arises from certain government agency agreements, as well as agreements with MI insurers, which limit the agency's repayment guarantees on foreclosed loans and allow compensatory fees and penalties and curtailments of claims for violations of agreements or insurance policies, resulting in losses to the servicer. Foreclosure exposure also includes real estate costs, marketing costs, and costs to maintain properties, especially during protracted resale periods in geographic areas of the country negatively impacted by declining home values.
For several years governmental officials and agencies have scrutinized industry foreclosure practices, particularly in judicial foreclosure states. The initial focus on judicial foreclosure practices of financial institutions nationwide expanded to include non-judicial foreclosure and loss mitigation practices including the effective coordination by servicers of foreclosure and loss mitigation activities. All of the changes to servicing practices including the additional oversight required arising out of this activity including those described below could impact FHN through increased operational and legal costs. FHN continues to review, monitor, and revise, as appropriate, its foreclosure processes and coordinated loss mitigation practices with the goal of conforming them to evolving servicing requirements.
In 2011 regulators entered into consent decrees with several institutions requiring comprehensive revision of loan modification and foreclosure processes, including the remediation of borrowers that have experienced financial harm. The 2008 subservicer was subject to a consent decree and its parent company agreed to pay related monetary sanctions, among other things. In 2012 the 2008 subservicer, along with certain others, entered into a settlement agreement with the OCC which replaced the consent decree. The new settlement required remediation for all borrowers with "in-process" foreclosures dating from 2009 or 2010 and certain other foreclosure-avoidance assistance from parties to the settlement. The remediation process was substantially completed in 2013.
Under FHN's 2008 subservicing agreement, the 2008 subservicer had the contractual right to follow FHN's prior servicing practices as they existed 180 days prior to August 2008 until the 2008 subservicer became aware that such practices did not comply with applicable servicing requirements, subject to the subservicer's obligation to follow accepted servicing practices, applicable law, and new requirements, including evolving interpretations of such practices, law and requirements. FHN cannot predict the amount of additional operating costs related to foreclosure delays, including required process changes, increased default services, extended periods of servicing advances and the recoverability of such advances, legal expenses, or other costs that may be incurred as a result of the internal reviews or external actions. In the event of a dispute such as that described below between FHN and the 2008 subservicer over any liabilities for subservicer's servicing and management of foreclosure or loss mitigation processes, FHN cannot predict the costs that may be incurred.
FHN's 2008 subservicer has presented invoices and made demands under the 2008 subservicing agreement that FHN pay certain costs related to tax service contracts, miscellaneous transfer costs, servicing timeline penalties, compensatory damages, and curtailments charged prior to the servicing transfer by GSEs and a government agency in connection with FHN's transfer of subservicing to its 2011 subservicer in the amount of $8.6 million. The 2008 subservicer also is seeking reimbursement from FHN for expenditures the 2008 subservicer has incurred or anticipates it will incur under the consent decree and supervisory guidance relating to foreclosure review (collectively, “foreclosure review expenditures”). The foreclosure review expenditures for which the 2008 subservicer has sought reimbursement total $34.9 million. Additional reimbursement requests may be made. FHN disputes that it has any responsibility or liability for either demand. In the event that the 2008 subservicer pursues its position through litigation, FHN believes it has meritorious defenses and intends to defend itself vigorously. FHN disagrees with the 2008 subservicer's position and has made no reimbursements. FHN also believes that certain amounts billed to FHN by agencies for penalties and curtailments on claims by MI insurers for actions by the 2008 subservicer prior to the 2011 subservicing transfer but billed after that date are owed by the 2008 subservicer. This disagreement has the potential to result in litigation and, in any such future litigation, the claim against FHN may be substantial.
Other Disclosures - Visa Matters
FHN is a member of the Visa USA network. In October 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 (the "Covered Litigation"). Based on its proportionate membership share of Visa USA, FHN recognized a contingent liability in fourth quarter 2007 related to this contingent obligation. In March 2008, Visa completed its initial public offering (“IPO”) and funded an escrow account from its IPO proceeds to be used to make payments related to the Visa litigation matters. FHN received approximately 2.4 million Class B shares in conjunction with Visa's IPO.
Conversion of these shares into Class A shares of Visa and, with limited exceptions, transfer of these shares is restricted until the final resolution of the covered litigation. In conjunction with the prior sales of Visa Class B shares in December 2010 and September 2011, FHN and the purchasers entered into derivative transactions whereby FHN will make, or receive, cash payments whenever the conversion ratio of the Visa Class B shares into Visa Class A shares is adjusted. The conversion ratio is adjusted when Visa deposits funds into the escrow account to cover certain litigation.
In July 2012, Visa and MasterCard announced a joint settlement (the "Settlement") related to the Payment Card Interchange matter, one of the Covered Litigation matters. Based on the amount of the Settlement attributable to Visa and an assessment of FHN's contingent liability accrued for Visa litigation matters, the Settlement did not have a material impact on FHN. As a result of the Settlement, Visa funded an additional $150 million into the escrow account in July 2012, and as a result FHN made a payment to the counterparty of $.8 million. As of December 31, 2013, the conversion ratio is 42 percent, and the contingent liability is $.8 million. Future funding of the escrow would dilute this exchange rate by an amount that is not determinable.
As of December 31, 2013 and 2012, the derivative liabilities were $2.9 million and $2.2 million, respectively.
FHN now holds approximately 1.1 million Visa Class B shares. FHN's Visa shares are not considered to be marketable and therefore are included in the Consolidated Statements of Condition at their historical cost of $0. The Settlement has been approved by the court but that approval has been appealed by certain of the plaintiffs. Accordingly, the outcome of this matter remains uncertain. Additionally, other Covered Litigation matters are also pending judicial resolution, including new matters filed by class members who opted-out of the Settlement. So long as any Covered Litigation matter remains pending, FHN's ability to transfer its Visa holdings continues to be restricted.
Other Disclosures – Indemnification Agreements and Guarantees
In the ordinary course of business, FHN enters into indemnification agreements for legal proceedings against its directors and officers and standard representations and warranties for underwriting agreements, merger and acquisition agreements, loan sales, contractual commitments, and various other business transactions or arrangements. The extent of FHN's obligations under these agreements depends upon the occurrence of future events; therefore, it is not possible to estimate a maximum potential amount of payouts that could be required with such agreements.

Pension, Savings, And Other Employee Benefits [Abstract]	'
Pension, Savings, And Other Employee Benefits	'
	Note 19 – Pension, Savings, and Other Employee Benefits
	Pension plan. FHN sponsors a noncontributory, qualified defined benefit pension plan to employees hired or re-hired on or before September 1, 2007. Pension benefits are based on years of service, average compensation near retirement or other termination, and estimated social security benefits at age 65. The contributions are based upon actuarially determined amounts necessary to fund the total benefit obligation. FHN did not make any contributions to the qualified pension plan in 2013. Future decisions to contribute to the plan will be based upon pension funding requirements under the Pension Protection Act, the maximum deductible under the Internal Revenue Code, and the actual performance of plan assets. Management has assessed the need for future contributions, and does not currently anticipate that FHN will make a contribution to the qualified pension plan in 2014.
	FHN also maintains non-qualified plans including a supplemental retirement plan that covers certain employees whose benefits under the qualified pension plan have been limited. These other non-qualified plans are unfunded, and contributions to these plans cover all benefits paid under the non-qualified plans. Payments made under the non-qualified plans were $5.4 million for 2013. FHN anticipates making benefit payments under the non-qualified plans of $5.1 million in 2014.
	The accrual of benefits under the qualified pension plan and the supplemental retirement plan ceased as of December 31, 2012. Starting in 2013, employees in the pension plan and those in the Employee Non voluntary Elective Contribution (“ENEC”) program have been able to participate in the FHN savings plan with an increased company match rate; in addition, a profit sharing feature has been available for employees who are not eligible to participate in a bonus program.
	Savings plan. FHN has a qualified defined contribution plan that covers substantially all employees. Under this plan, employees can invest their money in any of the available investment funds. In 2012 employees participating in the qualified pension plan received a company match of 50 percent of each $1.00 invested up to 6 percent of pre-tax contributions made by the employee, subject to Code limitations, while employees who started after the pension plan was closed to new hires received an additional contribution under the ENEC program discussed below. In 2012 the company match contribution initially was invested in company stock. Following the discontinuance of the accrual of benefits under the qualified pension plan as of December 31, 2012, an increased company match rate of 100 percent of each $1.00 invested applies to all employees up to 6 percent of pre-tax contributions made by the employee, subject to Code limitations, and match contributions no longer must be invested initially in company stock. The savings plan also allows employees to invest in a non-leveraged ESOP. Cash dividends on shares held by the ESOP are charged to retained earnings and the shares are considered outstanding in computing earnings per share. The number of allocated shares held by the ESOP totaled 9,715,343 on December 31, 2013.
	FHN also provides “flexible dollars” to assist employees with the cost of annual benefits and/or allow the employee to contribute to his or her qualified savings plan. These “flexible dollars” are pre-tax contributions and are based upon the employees' years of service and qualified compensation. Contributions made by FHN through the flexible benefits plan and the company matches were $20.4 million for 2013, $16.8 million for 2012 and $17.1 million for 2011.
	The ENEC program was added under the FHN savings plan and was provided only to employees not eligible for the pension plan. With the ENEC program, FHN will generally make contributions to eligible employees' savings plan accounts based upon company performance. Contribution amounts will be a percentage of each employee's base salary (as defined in the savings plan) earned the prior year. FHN contributed $1.7 million for the plan in 2013 related to the 2012 plan year, and FHN does not expect to contribute to the plan in 2014 related to the 2013 plan year. All contributions made to eligible employees' savings plan accounts in relation to the ENEC program were invested in company stock.
	Other employee benefits. FHN provides postretirement life insurance benefits to certain employees and also provides postretirement medical insurance to retirement-eligible employees. The postretirement medical plan is contributory with retiree contributions adjusted annually and is based on criteria that are a combination of the employee's age and years of service. For any employee retiring on or after January 1, 1995, FHN contributes a fixed amount based on years of service and age at the time of retirement. FHN's postretirement benefits include prescription drug benefits. The Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (“the Act”) introduced a prescription drug benefit under Medicare Part D as well as a federal subsidy to sponsors of retiree health care that provide a benefit that is actuarially equivalent to Medicare Part D. Beginning in 2014, FHN does not currently anticipate receiving a prescription drug subsidy under the Act. In third quarter 2013, FHN notified participants of revisions to the retiree medical plan effective January 1, 2014, which represented a negative plan amendment, the effects of which are being prospectively amortized beginning in third quarter 2013.
	Actuarial assumptions. FHN's process for developing the long-term expected rate of return of pension plan assets is based on capital market exposure as the source of investment portfolio returns. Capital market exposure refers to the plan's broad allocation of its assets to asset classes, such as large cap equity and fixed income. FHN also considers expectations for inflation, real interest rates, and various risk premiums based primarily on the historical risk premium for each asset class. The expected return is based upon a thirty year time horizon. Consequently, FHN selected a 6.60 percent assumption for 2014 for the defined benefit pension plan and a 2.85 percent assumption for postretirement medical plan assets dedicated to employees who retired prior to January 1, 1993.
	The discount rates for the three years ended 2013 for pension and other benefits were determined by using a hypothetical AA yield curve represented by a series of annualized individual discount rates from one-half to thirty years. The discount rates are selected based upon data specific to FHN's plans and employee population. The bonds used to create the hypothetical yield curve were subjected to several requirements to ensure that the resulting rates were representative of the bonds that would be selected by management to fulfill the company's funding obligations. In addition to the AA rating, only non-callable bonds were included. Each bond issue was required to have at least $250 million par outstanding so that each issue was sufficiently marketable. Finally, bonds more than two standard deviations from the average yield were removed. When selecting the discount rate, FHN matches the duration of high quality bonds with the duration of the obligations of the plan as of the measurement date. High quality corporate bonds experienced increasing yields in 2013 resulting in a discount rate higher than 2012 and therefore a lower benefit obligation. For all years presented, the measurement date of the benefit obligations and net periodic benefit costs was December 31.
	The actuarial assumptions used in the defined benefit pension plan and other employee benefit plans were as follows:
			Benefit Obligations									Net Periodic Benefit Cost
			2013			2012			2011			2013			2012		2011
	Discount rate
	Qualified pension		5.15%			4.35%			5.10%			4.35%			5.10%		5.70%
	Nonqualified pension		4.70%			3.85%			4.75%			3.85%			4.75%		5.10%
	Other nonqualified pension		4.05%			3.20%			4.40%			3.20%			4.40%		4.75%
	Postretirement benefits		4.10% - 5.35%			3.80% - 4.55%			4.75% - 5.25%			3.80% - 4.55%			4.75% - 5.25%		5.25% - 5.95%
	Expected long-term rate of return
	Qualified pension/postretirement benefits		6.60%			6.05%			6.90%			6.05%			6.90%		8.00%
	Postretirement benefit (retirees prior to January 1, 1993)		2.85%			3.93%			4.49%			3.93%			4.49%		5.20%
	Rate of compensation increase (a)		N/A			4.10%			4.10%			N/A			4.10%		4.10%
	(a) Due to the pension plan freeze as of December 31, 2012, the rate of compensation increase no longer applies to the qualified pension plan.
	The assumed health care cost trend rates used in the other employee benefit plan was as follows:
			2013 (a)					2012
	Assumed health care cost trend rates on December 31		Participants under age 65		Participants 65 years and older			Participants under age 65			Participants 65 years and older
	Health care cost trend rate assumed for next year		N/A		N/A			7.5	%		7.5	%
	Rate to which the cost trend rate is assumed to decline (the ultimate trend rate)		N/A		N/A			5	%		5	%
	Year that the rate reaches the ultimate trend rate		N/A		N/A			2019			2019
	(a)	Beginning in 2013, participants are no longer included in FHN's self-funded plan.
	The health care cost trend rate assumption has a significant effect on the amounts reported. A one-percentage-point change in assumed health care cost trend rates would have the following effects:
	(Dollars in thousands)		1% Increase			1% Decrease
	Adjusted total service and interest cost components		$	808		$	772
	Adjusted postretirement benefit obligation at end of plan year (a)			7,202			7,202
	(a)	Due to the pension plan freeze on December 31, 2012, trend rate assumptions no longer have an impact on benefit obligation.
	The components of net periodic benefit cost for the plan years 2013, 2012 and 2011 are as follows:
			Total Pension Benefits									Other Benefits
	(Dollars in thousands)		2013			2012			2011			2013			2012		2011
	Components of net periodic benefit cost

	Total periodic benefit costs	$	8,033		$	45,655		$	23,190		$	1,207		$	2,089	$	1,487
	(a)        2013 decline in total pension benefits service cost reflects the freeze of the pension plans effective December 31, 2012.
	(b)        2013 decline in recognition of total pension benefits actuarial loss driven by the change in amortization term from the estimated average remaining service period of active employees to the estimated average remaining life expectancy of the remaining participants in conjunction with the freeze of the pension plans on December 31, 2012.
	(c)        In 2013 and 2012, lump sum payments under the supplemental retirement plan triggered settlement accounting. In accordance with its practice, FHN performed a remeasurement of the plan in conjunction with the settlement and realized an ASC 715 settlement expense.
	The long-term expected rate of return is applied to the market-related value of plan assets in determining the expected return on plan assets. FHN determines the market-related value of plan assets using a calculated value that recognizes changes in the fair value of plan assets over five years, as permitted by GAAP
	The following tables set forth the plans' benefit obligations and plan assets for 2013 and 2012:

(a)       2013 decline in total pension benefits service cost reflects the freeze of the pension plans effective December 31, 2012.
(b)        2013 change in recognition of total pension benefits actuarial (gain)/loss driven by the change in amortization term from the estimated average remaining service period of active employees to the estimated average remaining life expectancy of the remaining participants in conjunction with the freeze of the pension plans on December 31, 2012. 2013 change in other benefits actuarial (gain)/loss driven by a change in the retiree medical plan.
The qualified and nonqualified pension plans were underfunded as of December 31, 2013, by $6.3 million, and $46.9 million, respectively. At year-end 2012, the qualified and nonqualified pension plans were underfunded by $80.3 million, and $52.7 million, respectively. Because of the pension freeze as of the end of 2012, the pension benefit obligation and the accumulated benefit obligation are the same as of December 31, 2013 and 2012. The projected benefit obligation and the accumulated benefit obligation for the qualified pension plan exceeded all corresponding plan assets as of December 31, 2013 and 2012.
Unrecognized transition assets and obligations, unrecognized actuarial gains and losses, and unrecognized prior service costs and credits are recognized as a component of accumulated other comprehensive income. Balances reflected in accumulated other comprehensive income on a pre-tax basis for the years ended December 31, 2013 and 2012 consist of:
	Total Pension Benefits						Other Benefits
(Dollars in thousands)	2013			2012			2013			2012
Amounts Recognized in Accumulated Other Comprehensive Income
Prior service cost/(credit)	$	927		$	1,280		$	-9,740		$	639

Total	$	242,868		$	325,793		$	-18,169		$	1,119
The pre-tax amounts recognized in other comprehensive income during 2013 and 2012 were as follows:

Total recognized in other comprehensive income		$	-82,931		$	18		$	-19,288		$	7,225
FHN utilizes the minimum amortization method in determining the amount of actuarial gains or losses to include in plan expense. Under this approach, the net deferred actuarial gain or loss that exceeds a threshold is amortized over the average remaining service period of active plan participants. The threshold is measured as the greater of: 10 percent of a plan's projected benefit obligation as of the beginning of the year or 10 percent of the market-related value of plan assets as of the beginning of the year. In conjunction with the freeze of the pension plans on December 31, 2012, all participants are considered inactive under applicable accounting guidance for determining the appropriate period for prospective amortization of actuarial gains and losses. Thus, effective January 1, 2013, FHN changed the amortization term for actuarial gains and losses from the estimated average remaining service period of active employees to the estimated average remaining life expectancy of the remaining participants.
The estimated net actuarial (gain)/loss, prior service cost/(credit), and transition (asset)/obligation for the plan that will amortize from accumulated other comprehensive income into net periodic benefit cost during the following fiscal year are as follows:
	Total Pension Benefits						Other Benefits

Plan assets. FHN's overall investment goal is to create, over the life of the pension plan and retiree medical plan, an adequate pool of sufficiently liquid assets to support the pension benefit obligations to participants, retirees, and beneficiaries, as well as to partially support the medical obligations to retirees and beneficiaries. Thus, the pension plan and retiree medical plan seek to achieve a high level of investment return consistent with a prudent level of portfolio risk.
During 2010, FHN adopted an investment strategy that will reduce equities and increase long duration fixed income allocations over time with the intention of reducing volatility of funded status and pension costs. At December 31, 2013 and 2012, the target allocation to equities was 32.5 percent and 37.5 percent, respectively and the target allocation to fixed income and cash equivalents was 67.5 percent and 62.5 percent, respectively. Equity securities, some of which are included in common and collective funds, primarily include investments in large capital and small capital companies located in the U.S., as well as international equity securities in developed and emerging markets. Fixed income securities include U.S. treasuries, corporate bonds of companies from diversified industries, mortgage backed securities, and foreign bonds. Fixed income investments generally have long durations consistent with the pension liabilities of FHN. Retiree medical funds are kept in short-term investments, primarily money market funds and mutual funds. On December 31, 2013 and 2012, FHN did not have any significant concentrations of risk within the plan assets related to the pension plan or the retiree medical plan.
The fair value of FHN's pension plan assets at December 31, 2013 and December 31, 2012, by asset category classified using the Fair Value measurement hierarchy is shown in the table below. See Note 22 – Fair Value of Assets and Liabilities for more details about Fair Value measurements.

Any shortfall of investment performance compared to investment objectives should be explainable in terms of general economic and capital market conditions. The Retirement Investment Committee, comprised of senior managers within the organization, meets at least quarterly to review asset performance and potential portfolio rebalancing. Rebalancing of pension assets is based upon a de-risking glide path as well as liquidity needs for plan benefits. Rebalancing occurs on a quarterly basis or as improvements in funded status merit changes to the targeted allocations, as defined in the de-risking glide path. The Committee also periodically reviews other elements of risk for its pension investment program, including the organization's ability to assume pension investment risk.

Stock Option, Restricted Stock Incentive, And Dividend Reinvestment Plans [Text Block]	'
	Note 20 – Stock Option, Restricted Stock Incentive, and Dividend Reinvestment Plans
	Equity compensation plans
	FHN currently has one plan, its shareholder-approved Equity Compensation Plan ("ECP"), which authorizes the grant of new stock-based awards to employees and directors. Outstanding awards generally were granted under the ECP, though older stock options and certain cash-settled stock units remain outstanding under several plans which no longer are active. The ECP authorizes a broad range of award types, including restricted shares, stock units, and stock options. Stock units may be paid in shares or cash, depending upon the terms of the award. The ECP also authorizes the grant of stock appreciation rights, though no such grants have been made. Awards generally have service-vesting conditions, meaning that the employee must remain employed by FHN for certain periods in order for the award to vest. Some outstanding awards also have performance conditions, and one outstanding award has performance conditions associated with FHN's stock price. FHN operates the ECP by establishing award programs, each of which is intended to cover a specific need. Programs are created, changed, or terminated as needs change. Unvested awards have service and/or performance conditions which must be met in order for the shares to vest. On December 31, 2013, there were 9,410,603 shares available for new awards under the ECP. Although the ECP imposes a separate limit on full-value (non-option) awards which is included within the overall limit, at December 31, 2013 the two limits were the same.
	Service condition full-value awards. Awards may be granted with service conditions only. In recent years programs using these awards have included an annual program for selected management employees, a mandatory deferral program for executives tied to annual bonuses earned, a salary stock unit program for executives, other mandatory deferral programs, various retention programs, and special hiring-incentive situations. Details of the awards vary by program, but most are settled in shares at vesting rather than cash, and vesting rarely begins earlier than the first anniversary of grant and rarely extends beyond the fourth anniversary of grant. Annual programs tend to use multiple annual vesting dates while retention programs tend to use a single vesting date, but there are exceptions.
	Performance condition awards. Under FHN's long-term incentive and corporate performance programs, performance stock units (executives) and cash units (selected management employees) are granted annually and vest only if predetermined performance measures are met. The measures are changed each year based on goals and circumstances prevailing at the time of grant. In recent years the performance periods have been three years, with service-vesting on the third anniversary of the grant. Recent annual performance awards require pro-rated forfeiture for performance falling between a threshold level and a maximum, but all-or-nothing awards have been granted and were outstanding at year-end. Performance awards sometimes are used to provide a narrow, targeted incentive to a single person or small group; one such award which represents a market performance condition to FHN's CEO is discussed in the next paragraph and another such award, to a senior manager, remained outstanding at year-end. Of the annual program awards paid during 2013 or outstanding on December 31, 2013: performance conditions related to the 2009 units were met, and 50 percent of the units vested in 2013; performance conditions related to the 2010 units were met at the 50 percent payout level, so that 25 percent were paid in 2013 and 25 percent in 2014 with the remaining 50 percent forfeited; the three-year performance period of the 2011 units has ended but performance is measured relative to peers and has not yet been determined; and, the three-year performance periods for the 2012 and 2013 units have not ended. The performance award granted to a senior manager has been partially achieved.
	Market condition award. In 2012, FHN made a special grant of performance stock units to FHN's Chief Executive Officer which will vest at the end of a five year performance period. The award has no provision for pro-rated payment based on partial performance. The award's two alternative performance goals are: FHN's common stock price achieves and maintains a certain level for a certain period of time; or FHN's total shareholder return during the entire period achieves a certain level.
	Director awards. Non-employee directors receive annual grants of service-conditioned stock units under a program approved by the board of directors. Through the first quarter of 2013, directors received $45,000 of their annual retainer in the form of stock units which vested the following year and were paid in shares. Starting with the annual meeting in second quarter 2013, the program was changed to replace cash meeting fees with additional stock units, and to award additional units to the lead director. The amount of additional units granted varies with committee assignment, and the additional units are paid in cash rather than shares, but in other respects they are similar to the retainer units, which were unchanged. Prior to 2007 the board granted 8,930 shares of restricted stock to each new non-employee director upon election to the board, with restrictions lapsing at a rate of ten percent per year. That program was discontinued in 2007, although a few legacy awards remain outstanding.
	The summary of restricted and performance stock and unit activity during the year ended December 31, 2013, is presented below:
		Shares/Units		Weighted average grant date fair value
	Nonvested on January 1, 2013	4,672,815	$	10.21
	Shares/units granted	1,154,540		10.63
	Shares/units vested	-1,431,421		9.34
	Shares/units cancelled	-221,738		10.4
	Nonvested on December 31, 2013	4,174,196	$	10.51
	The weighted average grant date fair value for shares/units granted in 2012 and 2011 was $9.25 and $10.75, respectively.
	On December 31, 2013, there was $16.0 million of unrecognized compensation cost related to nonvested restricted stock awards. That cost is expected to be recognized over a weighted-average period of 2.4 years. The total grant date fair value of shares vested during 2013, 2012 and 2011, was $13.8 million, $12.1 million and $5.1 million, respectively.
	Stock option awards. Currently FHN operates only a single option program, calling for annual grants of service-vested options to executives. In the past, however, option programs varied widely in their uses and terms, and many old-program options, granted under the ECP or its predecessor plans, remain outstanding today. All options granted since 2005 provide for the issuance of FHN common stock at a price fixed at its fair market value on the grant date. All options granted since 2008 vest fully no later than the fourth anniversary of grant, and all such options expire seven years from the grant date. A deferral program, which was discontinued in 2005, allowed for foregone compensation plus the exercise price to equal the fair market value of the stock on the date of grant if the grantee agreed to receive the options in lieu of compensation. Deferral options granted prior to January 2, 2004, expire 20 years from the grant date, while those granted in the final year of that program have only ten-year terms. FHN granted no stock options in 2009 or 2010.
	The summary of stock option activity for the year ended December 31, 2013, is shown below:
		Options Outstanding		Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (years)		Aggregate Intrinsic Value (thousands)
	1-Jan-13	9,796,648	$	21.26
	Options granted	866,742		10.82
	Options exercised	-64,085		10.37
	Options expired/cancelled	-2,006,130		25.63
	31-Dec-13	8,593,175		19.29		4.06	$	4,094
	Options exercisable	6,485,156		22.16		3.67		1,511
	Options expected to vest	2,108,019		10.46		5.26		2,583
	The total intrinsic value of options exercised during 2013, 2012, and 2011 was immaterial. On December 31, 2013, there was $2.4 million of unrecognized compensation cost related to nonvested stock options. That cost is expected to be recognized over a weighted-average period of 2.6 years.
	FHN granted 866,742, 1,248,685 and 1,005,224 stock options with a weighted average fair value of $3.21, $3.80 and $5.21 per option at grant date in 2013, 2012 and 2011, respectively.
	FHN used the Black-Scholes Option Pricing Model to estimate the fair value of stock options granted in 2013, 2012, and 2011 with the following assumptions:
		2013	2012		2011
	Expected dividend yield	1.84%	0.42%		0.34%
	Expected weighted-average lives of options granted	6.12 years	6.11 years		6.59 years
	Expected weighted-average volatility	36.19%	42.40%		40.70%
	Expected volatility range	27.27 - 62.98%	35.80 - 62.21%		35.04 - 57.69%
	Risk-free interest rate	1.16%	1.10%		2.91%
	Expected lives of options granted are determined based on the vesting period, historical exercise patterns and contractual term of the options. For options granted in 2013, 2012, and 2011, FHN used a blended volatility rate in order to more accurately reflect expected volatility. A portion of the weighted average volatility rate was derived by compiling daily closing stock prices over a historical period approximating the expected lives of the options. Additionally, because of market volatility experienced during this time period related to economic conditions and the impact on stock prices of financial institutions, FHN also incorporated a measure of implied volatility so as to incorporate more recent, normalized market conditions that are considered to better reflect future volatility.
	Compensation Cost. The compensation cost that has been included in income from continuing operations pertaining to stock-based awards was $16.1 million, $16.2 million, and $14.2 million for 2013, 2012, and 2011, respectively. The corresponding total income tax benefits recognized were $6.2 million in 2013 and 2012 and $5.4 million for 2011.
	Authorization. Consistent with Tennessee state law, only authorized, but unissued, stock may be utilized in connection with any issuance of FHN common stock which may be required as a result of stock based compensation awards. FHN generally obtains authorization from the Board of Directors to repurchase any stock that may be issued at the time a plan is approved or amended. These authorizations are automatically adjusted for stock splits and stock dividends. Repurchases are authorized to be made in the open market or through privately negotiated transactions and will be subject to market conditions, accumulation of excess equity, legal and regulatory restrictions, and prudent capital management. FHN does not currently expect to repurchase a material number of shares under the compensation plan-related repurchase program during the next annual period.
	Dividend reinvestment plan. The Dividend Reinvestment and Stock Purchase Plan authorizes the sale of FHN's common stock from stock acquired on the open market to shareholders who choose to invest all or a portion of their cash dividends or make optional cash payments of $25 to $10,000 per quarter without paying commissions. The price of stock purchased on the open market is the average price paid.

Business Segment Information [Abstract]	'
Business Segment Information	'
	Note 21 – Business Segment Information
	FHN has four business segments: regional banking, capital markets, corporate, and non-strategic. The regional banking segment offers financial products and services, including traditional lending and deposit taking, to retail and commercial customers largely in Tennessee and other selected markets. Regional banking provides investments, financial planning, trust services and asset management, credit card, and cash management. Additionally, the regional banking segment includes correspondent banking which provides credit, depository, and other banking related services to other financial institutions nationally. The capital markets segment consists of fixed income sales, trading, and strategies for institutional clients in the U.S. and abroad, as well as loan sales, portfolio advisory, and derivative sales. The corporate segment consists of gains on the extinguishment of debt, unallocated corporate expenses, expense on subordinated debt issuances, bank-owned life insurance, unallocated interest income associated with excess equity, net impact of raising incremental capital, revenue and expense associated with deferred compensation plans, funds management, tax credit investment activities, acquisition-related costs, and various charges related to restructuring, repositioning, and efficiency initiatives. The non-strategic segment consists of the wind-down national consumer lending activities, legacy mortgage banking elements including servicing fees, and the associated ancillary revenues and expenses related to these businesses. Non-strategic also includes the wind-down trust preferred loan portfolio and exited businesses along with the associated restructuring, repositioning, and efficiency charges.
	Periodically, FHN adapts its segments to reflect managerial or strategic changes. FHN may also modify its methodology of allocating expenses and equity among segments which could change historical segment results. Total revenue, expense, and asset levels reflect those which are specifically identifiable or which are allocated based on an internal allocation method. Because the allocations are based on internally developed assignments and allocations, they are to an extent subjective. Generally, all assignments and allocations have been consistently applied for all periods presented. The following table reflects the amounts of consolidated revenue, expense, tax, and assets for each segment for the years ended December 31:

Fair Value Disclosures [Abstract]	'
Fair Value Of Assets And Liabilities	'
	Note 22 – Fair Value of Assets & Liabilities
	FHN groups its assets and liabilities measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. This hierarchy requires FHN to maximize the use of observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. Each fair value measurement is placed into the proper level based on the lowest level of significant input. These levels are:
	Level 1 - Valuation is based upon quoted prices for identical instruments traded in active markets.
	Level 2 - Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.
	Level 3 - Valuation is generated from model-based techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect management's estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models, and similar techniques.
	Transfers between fair value levels are recognized at the end of the fiscal quarter in which the associated change in inputs occurs.
	Recurring Fair Value Measurements
	The following table presents the balance of assets and liabilities measured at fair value on a recurring basis as of December 31, 2013:

Primarily included in mortgage banking income on the Consolidated Statements of Income.
Represents recognized gains and losses attributable to venture capital investments classified within securities available-for-sale that are included in securities gains/(losses) in noninterest income.
Transfers out of recurring loans held-for-sale level 3 balances reflect movements out of loans held-for-sale and into real estate acquired by foreclosure (level 3 nonrecurring).
Included in Other expense.
In fourth quarter 2012, FHN determined that the level of market information on prepayment speeds and discount rates associated with its principal only trading securities had become more limited. In response, FHN increased its use of unobservable inputs and transferred these balances to Level 3.
Nonrecurring Fair Value Measurements
From time to time, FHN may be required to measure certain other financial assets at fair value on a nonrecurring basis in accordance with GAAP. These adjustments to fair value usually result from the application of LOCOM accounting or write-downs of individual assets. For assets measured at fair value on a nonrecurring basis which were still held on the balance sheet at December 31, 2013, 2012, and 2011, respectively, the following tables provide the level of valuation assumptions used to determine each adjustment, the related carrying value, and the fair value adjustments recorded during the respective periods.

In first quarter 2011, FHN recognized goodwill impairment of $10.1 million related to the contracted sale of FHI. In accordance with accounting requirements, FHN allocated a portion of the goodwill from the applicable reporting unit to the asset group held-for-sale in determining the carrying value of the disposal group. In determining the amount of impairment, FHN compared the carrying value of the disposal group to the estimated value of the contracted sale price, which primarily included observable inputs in the form of financial asset values but which also included certain nonobservable inputs related to the estimated values of post-closing events and contingencies. Thus, this measurement was considered a Level 3 valuation. Impairment of goodwill was recognized for the excess of the carrying amount over the fair value of the disposal group.
In first quarter 2013, third quarter 2012 and second quarter 2011, FHN exercised clean-up calls on first lien mortgage proprietary securitization trusts. In accordance with accounting requirements, FHN initially recognized the associated loans at fair value. Fair value was primarily determined through reference to observable inputs, including current market prices for similar loans. Since these loans were from the 2003 vintage, adjustments were made for the higher yields associated with the loans in comparison to more currently originated loans being sold. This resulted in recognition of an immaterial premium for these transactions.

Loans held-for-sale. Prepayment rates, credit spreads, delinquency adjustment factors and draw rates are significant unobservable inputs used in the fair value measurement of FHN's residential real estate loans held-for-sale. Loss severity trends are also assessed to evaluate the reasonableness of fair value estimates resulting from discounted cash flows methodologies as well as to estimate fair value for newly repurchased loans and loans that are near foreclosure. Significant increases (decreases) in any of these inputs in isolation would result in significantly lower (higher) fair value measurements. All observable and unobservable inputs are re-assessed monthly. Increases (decreases) in the draw rate estimates for HELOCs would increase (decrease) their fair value. Fair value measurements are reviewed at least monthly by FHN's Corporate Accounting Department.
Venture capital investments. The unobservable inputs used in the estimation of fair value for Venture capital investments are adjustments for minority interest and small business status when compared to industry comparables and the discount rate and earnings capitalization rate for a discounted cash flow analysis. For both valuation techniques, the inputs are intended to reflect the nature of the small business and the status of equity tranches held by FHN in relation to the overall valuation. The valuation of venture capital investments is reviewed at least quarterly by FHN's Equity Investment Review Committee. Changes in valuation are discussed with respect to the appropriateness of the adjustments in relation to the associated triggering events.
Derivative liabilities. The determination of fair value for FHN's derivative liabilities associated with its prior sales of Visa Class B shares include estimation of both the resolution amount for Visa's Covered Litigation matters as well as the length of time until the resolution occurs. Significant increases (decreases) in either of these inputs in isolation would result in significantly higher (lower) fair value measurements for the derivative liabilities. Additionally, FHN performs a probability weighted multiple resolution scenario to calculate the estimated fair value of these derivative liabilities. Assignment of higher (lower) probabilities to the larger potential resolution scenarios would result in an increase (decrease) in the estimated fair value of the derivative liabilities. The valuation inputs and process are discussed with senior and executive management when significant events affecting the estimate of fair value occur. Inputs are compared to information obtained from the public issuances and filings of Visa, Inc. as well as public information released by other participants in the applicable litigation matters.
Loans, net of unearned income and Real estate acquired by foreclosure. Collateral-dependent loans and Real estate acquired by foreclosure are primarily valued using appraisals based on sales of comparable properties in the same or similar markets. Multiple appraisal firms are utilized to ensure that estimated values are consistent between firms. This process occurs within FHN's Credit Risk Management and Loan Servicing functions (primarily consumer) and the Credit Risk Management Committee reviews valuation methodologies and loss information for reasonableness. Back testing is performed during the year through comparison to ultimate disposition values and is reviewed quarterly within the Credit Risk Management function. Other collateral (receivables, inventory, equipment, etc.) is valued through borrowing base certificates, financial statements and/or auction valuations. These valuations are discounted based on the quality of reporting, knowledge of the marketability/collectability of the collateral and historical disposition rates.
Other assets – tax credit investments. The estimated fair value of tax credit investments is generally determined in relation to the yield (i.e., future tax credits to be received) an acquirer of these investments would expect in relation to the yields experienced on current new issue and/or secondary market transactions. Thus, as tax credits are recognized, the future yield to a market participant is reduced, resulting in consistent impairment of the individual investments. Individual investments are reviewed for impairment quarterly, which may include the consideration of additional marketability discounts related to specific investments. Unusual valuation adjustments, and the associated triggering events, are discussed with senior and executive management, when appropriate. A portfolio review is conducted annually, with the assistance of a third party, to assess the reasonableness of current valuations.
Fair Value Option
FHN elected the fair value option on a prospective basis for almost all types of mortgage loans originated for sale purposes under the Financial Instruments Topic (“ASC 825”). FHN determined that the election reduced certain timing differences and better matched changes in the value of such loans with changes in the value of derivatives used as economic hedges for these assets at the time of election. After the 2008 divestiture of certain mortgage banking operations and the significant decline of mortgage loans originated for sale, FHN discontinued hedging the mortgage warehouse.
Repurchased loans are recognized within loans held-for-sale at fair value at the time of repurchase, which includes consideration of the credit status of the loans and the estimated liquidation value. FHN has elected to continue recognition of these loans at fair value in periods subsequent to reacquisition. Due to the credit-distressed nature of the vast majority of repurchased loans and the related loss severities experienced upon repurchase, FHN believes that the fair value election provides a more timely recognition of changes in value for these loans that occur subsequent to repurchase. Absent the fair value election, these loans would be subject to valuation at the LOCOM value, which would prevent subsequent values from exceeding the initial fair value, determined at the time of repurchase but would require recognition of subsequent declines in value. Thus, the fair value election provides for a more timely recognition of any potential future recoveries in asset values while not affecting the requirement to recognize subsequent declines in value.
Prior to 2010, FHN transferred certain servicing assets in transactions that did not qualify for sale treatment due to certain recourse provisions. In fourth quarter 2013, these recourse provisions expired and the transaction was recognized as a sale. The associated proceeds were recognized within other short-term borrowings in the Consolidated Statements of Condition. Since the servicing assets were recognized at fair value and changes in the fair value of the related financing liabilities mirrored the change in fair value of the associated servicing assets, management elected to account for the financing liabilities at fair value. Since the servicing assets had already been delivered to the buyer, the fair value of the financing liabilities associated with the transaction did not reflect any instrument-specific credit risk.
The following tables reflect the differences between the fair value carrying amount of residential real estate loans held-for-sale measured at fair value in accordance with management’s election and the aggregate unpaid principal amount FHN is contractually entitled to receive at maturity.

Assets and liabilities accounted for under the fair value election are initially measured at fair value with subsequent changes in fair value recognized in earnings. Such changes in the fair value of assets and liabilities for which FHN elected the fair value option are included in current period earnings with classification in the income statement line item reflected in the following table:
				Twelve Months Ended

		Loans held-for-sale	$	-4,387		$	-2,618		$	-368
		Other short-term borrowings		-3			3,677			12,476
For the twelve months ended December 31, 2013 , 2012, and 2011, the amounts for residential real estate loans held-for-sale include losses of $1.5 million, $1.8 million, and $6.2 million, respectively, included in pretax earnings that are attributable to changes in instrument-specific credit risk. The portion of the fair value adjustments related to credit risk was determined based on both a quality adjustment for delinquencies and the full credit spread on the non-conforming loans. Interest income on residential real estate loans held-for-sale measured at fair value is calculated based on the note rate of the loan and is recorded in the interest income section of the Consolidated Statements of Income as interest on loans held-for-sale.
Determination of Fair Value
In accordance with ASC 820-10-35, fair values are based on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The following describes the assumptions and methodologies used to estimate the fair value of financial instruments and MSR recorded at fair value in the Consolidated Statements of Condition and for estimating the fair value of financial instruments for which fair value is disclosed under ASC 825-10-50.
Short-term financial assets. Federal funds sold, securities purchased under agreements to resell, and interest bearing deposits with other financial institutions and the Federal Reserve are carried at historical cost. The carrying amount is a reasonable estimate of fair value because of the relatively short time between the origination of the instrument and its expected realization.
Trading securities and trading liabilities. Trading securities and trading liabilities are recognized at fair value through current earnings. Trading inventory held for broker-dealer operations is included in trading securities and trading liabilities. Broker-dealer long positions are valued at bid price in the bid-ask spread. Short positions are valued at the ask price. Inventory positions are valued using observable inputs including current market transactions, LIBOR and U.S. treasury curves, credit spreads, and consensus prepayment speeds. Trading loans are valued using observable inputs including current market transactions, swap rates, mortgage rates, and consensus prepayment speeds.
Trading securities also include retained interests in prior securitizations that qualify as financial assets, which primarily include excess interest, interest-only strips and principal-only strips.
The fair value of excess interest is determined using prices from closely comparable assets such as MSR that are tested against prices determined using a valuation model that calculates the present value of estimated future cash flows. Inputs utilized in valuing excess interest are consistent with those used to value the related MSR. The fair value of excess interest typically changes based on changes in the discount rate and differences between modeled prepayment speeds and credit losses and actual experience. FHN uses assumptions in the model that it believes are comparable to those used by brokers and other service providers. FHN also periodically compares its estimates of fair value and assumptions with brokers, service providers, recent market activity, and against its own experience. FHN uses inputs including yield curves, credit spreads, and prepayment speeds to determine the fair value of principal-only strips.
In third quarter 2013, FHN agreed to sell substantially all of its remaining legacy mortgage servicing, including excess interest. FHN used the price in the definitive agreement, as adjusted for the portion of pricing that was not specific to the excess interest, as a third-party pricing source in the valuation of the excess interest.
Securities available-for-sale. Securities available-for-sale includes the investment portfolio accounted for as available-for-sale under ASC 320-10-25, federal bank stock holdings, short-term investments in mutual funds, and venture capital investments. Valuations of available-for-sale securities are performed using observable inputs obtained from market transactions in similar securities. Typical inputs include LIBOR and U.S. treasury curves, consensus prepayment estimates, and credit spreads. When available, broker quotes are used to support these valuations. Certain government agency debt obligations with limited trading activity are valued using a discounted cash flow model that incorporates a combination of observable and unobservable inputs. Primary observable inputs include contractual cash flows and the treasury curve. Significant unobservable inputs include estimated trading spreads and estimated prepayment speeds.
Investments in the stock of the Federal Reserve Bank and Federal Home Loan Banks are recognized at historical cost in the Consolidated Statements of Condition which is considered to approximate fair value. Short-term investments in mutual funds are measured at the funds' reported closing net asset values. Venture capital investments are typically measured using significant internally generated inputs including adjustments to industry comparables and discounted cash flows analysis.
Loans held-for-sale. FHN determines the fair value of residential real estate loans held-for-sale using a discounted cash flow model which incorporates both observable and unobservable inputs. Typical inputs include contractual cash flow requirements, current mortgage rates for similar products, estimated prepayment rates, credit spreads and delinquency penalty adjustments. Adjustments for delinquency and other differences in loan characteristics are typically reflected in the model's discount rates. Loss severity trends and the value of underlying collateral are also considered in assessing the appropriate fair value for severely delinquent loans and loans in foreclosure. The valuation of HELOCs also incorporates estimates of loan draw rates as well as estimated cancellation rates for loans expected to become delinquent.
Loans held-for-sale also includes loans made by the Small Business Administration (“SBA”), which are accounted for at LOCOM. The fair value of SBA loans is determined using an expected cash flow model that utilizes observable inputs such as the spread between LIBOR and prime rates, consensus prepayment speeds, and the treasury curve. The fair value of other non-residential real estate loans held-for-sale is approximated by their carrying values based on current transaction values.
Loans, net of unearned income. Loans, net of unearned income are recognized at the amount of funds advanced, less charge-offs and an estimation of credit risk represented by the allowance for loan losses. The fair value estimates for disclosure purposes differentiate loans based on their financial characteristics, such as product classification, vintage, loan category, pricing features, and remaining maturity.
The fair value of floating rate loans is estimated through comparison to recent market activity in loans of similar product types, with adjustments made for differences in loan characteristics. In situations where market pricing inputs are not available, fair value is considered to approximate book value due to the monthly repricing for commercial and consumer loans, with the exception of floating rate 1-4 family residential mortgage loans which reprice annually and will lag movements in market rates. The fair value for floating rate 1-4 family mortgage loans is calculated by discounting future cash flows to their present value. Future cash flows are discounted to their present value by using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same time period.
Prepayment assumptions based on historical prepayment speeds and industry speeds for similar loans have been applied to the floating rate 1-4 family residential mortgage portfolio.
The fair value of fixed rate loans is estimated through comparison to recent market activity in loans of similar product types, with adjustments made for differences in loan characteristics. In situations where market pricing inputs are not available, fair value is estimated by discounting future cash flows to their present value. Future cash flows are discounted to their present value by using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same time period. Prepayment assumptions based on historical prepayment speeds and industry speeds for similar loans have been applied to the fixed rate mortgage and installment loan portfolios.
For all loan portfolio classes, adjustments are made to reflect liquidity or illiquidity of the market. Such adjustments reflect discounts that FHN believes are consistent with what a market participant would consider in determining fair value given current market conditions.
Individually impaired loans are measured using either a discounted cash flow methodology or the estimated fair value of the underlying collateral less costs to sell, if the loan is considered collateral-dependent. In accordance with accounting standards, the discounted cash flow analysis utilizes the loan's effective interest rate for discounting expected cash flow amounts. Thus, this analysis is not considered a fair value measurement in accordance with ASC 820. However, the results of this methodology are considered to approximate fair value for the applicable loans. Expected cash flows are derived from internally-developed inputs primarily reflecting expected default rates on contractual cash flows. For loans measured using the estimated fair value of collateral less costs to sell, fair value is estimated using appraisals of the collateral. Collateral values are monitored and additional write-downs are recognized if it is determined that the estimated collateral values have declined further. Estimated costs to sell are based on current amounts of disposal costs for similar assets. Carrying value is considered to reflect fair value for these loans.
Mortgage servicing rights. FHN recognizes all classes of MSR at fair value. Since sales of MSR tend to occur in private transactions and the precise terms and conditions of the sales are typically not readily available, there is a limited market to refer to in determining the fair value of MSR. As such, FHN primarily relies on a discounted cash flow model to estimate the fair value of its MSR. This model calculates estimated fair value of the MSR using predominant risk characteristics of MSR such as interest rates, type of product (fixed vs. variable), age (new, seasoned, or moderate), agency type and other factors. FHN uses assumptions in the model that it believes are comparable to those used by brokers and other service providers. FHN also periodically compares its estimates of fair value and assumptions with brokers, service providers, recent market activity, and against its own experience.
In third quarter 2013, FHN agreed to sell substantially all of its remaining legacy mortgage servicing. FHN used the price in the definitive agreement, as adjusted for the portion of pricing that was not specific to the MSR, as a third-party pricing source in the valuation of the MSR held at December 31, 2013.
Derivative assets and liabilities. The fair value for forwards and futures contracts is based on current transactions involving identical securities. Futures contracts are exchange-traded and thus have no credit risk factor assigned as the risk of non-performance is limited to the clearinghouse used.
Valuations of other derivatives (primarily interest rate related swaps, swaptions, caps, and collars) are based on inputs observed in active markets for similar instruments. Typical inputs include the LIBOR curve, Overnight Indexed Swap ("OIS") curve, option volatility, and option skew. In measuring the fair value of these derivative assets and liabilities, FHN has elected to consider credit risk based on the net exposure to individual counterparties. Credit risk is mitigated for these instruments through the use of mutual margining and master netting agreements as well as collateral posting requirements. Any remaining credit risk related to interest rate derivatives is considered in determining fair value through evaluation of additional factors such as customer loan grades and debt ratings. Foreign currency related derivatives also utilize observable exchange rates in the determination of fair value.
In conjunction with the sales of portions of its Visa Class B shares, FHN and the purchasers entered into derivative transactions whereby FHN will make, or receive, cash payments whenever the conversion ratio of the Visa Class B shares into Visa Class A shares is adjusted. The fair value of these derivatives has been determined using a discounted cash flow methodology for estimated future cash flows determined through use of probability weighted scenarios for multiple estimates of Visa's aggregate exposure to covered litigation matters, which include consideration of amounts funded by Visa into its escrow account for the covered litigation matters. Since this estimation process required application of judgment in developing significant unobservable inputs used to determine the possible outcomes and the probability weighting assigned to each scenario, these derivatives have been classified within Level 3 in fair value measurements disclosures.
Real estate acquired by foreclosure. Real estate acquired by foreclosure primarily consists of properties that have been acquired in satisfaction of debt. These properties are carried at the lower of the outstanding loan amount or estimated fair value less estimated costs to sell the real estate. Estimated fair value is determined using appraised values with subsequent adjustments for deterioration in values that are not reflected in the most recent appraisal. Real estate acquired by foreclosure also includes properties acquired in compliance with HUD servicing guidelines which are carried at the estimated amount of the underlying government insurance or guarantee.
Nonearning assets. For disclosure purposes, nonearning assets include cash and due from banks, accrued interest receivable, and capital markets receivables. Due to the short-term nature of cash and due from banks, accrued interest receivable, and capital markets receivables, the fair value is approximated by the book value.
Other assets. For disclosure purposes, other assets consist of tax credit investments and deferred compensation assets that are considered financial assets. Tax credit investments are written down to estimated fair value quarterly based on the estimated value of the associated tax credits. Deferred compensation assets are recognized at fair value, which is based on quoted prices in active markets.
Defined maturity deposits. The fair value is estimated by discounting future cash flows to their present value. Future cash flows are discounted by using the current market rates of similar instruments applicable to the remaining maturity. For disclosure purposes, defined maturity deposits include all certificates of deposit and other time deposits.
Undefined maturity deposits. In accordance with ASC 825, the fair value is approximated by the book value. For the purpose of this disclosure, undefined maturity deposits include demand deposits, checking interest accounts, savings accounts, and money market accounts.
Short-term financial liabilities. The fair value of federal funds purchased, securities sold under agreements to repurchase and other short-term borrowings are approximated by the book value. The carrying amount is a reasonable estimate of fair value because of the relatively short time between the origination of the instrument and its expected realization. Prior to fourth quarter 2013, Other short-term borrowings included a liability associated with transfers of MSR that did not qualify for sale accounting. This liability was accounted for at elected fair value, which was measured consistent with the related MSR, as previously described.
Term borrowings. The fair value is based on quoted market prices or dealer quotes for the identical liability when traded as an asset. When pricing information for the identical liability is not available, relevant prices for similar debt instruments are used with adjustments being made to the prices obtained for differences in characteristics of the debt instruments. If no relevant pricing information is available, the fair value is approximated by the present value of the contractual cash flows discounted by the investor's yield which considers FHN's and FTBNA's debt ratings.
Other noninterest-bearing liabilities. For disclosure purposes, other noninterest-bearing liabilities include accrued interest payable and capital markets payables. Due to the short-term nature of these liabilities, the book value is considered to approximate fair value.
Loan commitments. Fair values are based on fees charged to enter into similar agreements taking into account the remaining terms of the agreements and the counterparties' credit standing.
Other commitments. Fair values are based on fees charged to enter into similar agreements.
The following fair value estimates are determined as of a specific point in time utilizing various assumptions and estimates. The use of assumptions and various valuation techniques, as well as the absence of secondary markets for certain financial instruments, will likely reduce the comparability of fair value disclosures between financial institutions. Due to market illiquidity, the fair values for loans, net of unearned income, loans held-for-sale, and term borrowings as of December 31, 2013 and 2012, involve the use of significant internally-developed pricing assumptions for certain components of these line items. These assumptions are considered to reflect inputs that market participants would use in transactions involving these instruments as of the measurement date. Assets and liabilities that are not financial instruments (including MSR) have not been included in the following table such as the value of long-term relationships with deposit and trust customers, premises and equipment, goodwill and other intangibles, deferred taxes, and certain other assets and other liabilities. Accordingly, the total of the fair value amounts does not represent, and should not be construed to represent, the underlying value of the Company.
The following tables summarize the book value and estimated fair value of financial instruments recorded in the Consolidated Statements of Condition as well as unfunded commitments as of December 31, 2013 and 2012.

	Note 23 – Loan Sales and Securitizations
	Prior to 2009, FHN utilized loan sales and securitizations as a significant source of liquidity for its mortgage banking operations. FHN no longer retains financial interests in loans it transfers to third parties. During 2013 and 2012 loan sale activity was not material. In third quarter 2011, FHN transferred $187.7 million in unpaid principal balance ($126.0 million after consideration of partial charge-offs and associated LOCOM) of non-performing permanent mortgages in a bulk sale resulting in $29.8 million of net pre-tax losses in provision for loan losses on the Consolidated Statements of Income.
	Retained Interests
	Interests retained from prior loan sales, including GSE securitizations, typically included MSR, excess interest (structured as interest-only ("IO") strips), and principal-only ("PO") strips. Excess interest represents rights to receive interest from serviced assets that exceed contractually specified rates. PO strips are principal cash flow tranches. MSR were initially valued at fair value and the remaining retained interests were initially valued by allocating the remaining cost basis of the loan between the security or loan sold and the remaining retained interests based on their relative fair values at the time of sale or securitization.
	In certain cases, FHN continues to service and receive servicing fees related to the transferred loans. During 2013 and 2012, FHN received annual servicing fees approximating .31 percent and .29 percent, respectively, of the outstanding balance of underlying single-family residential mortgage loans and .34 percent inclusive of income related to excess interest. In 2013 and 2012, FHN received annual servicing fees approximating .50 percent of the outstanding balance of underlying loans for HELOC and home equity loans transferred. MSR related to loans transferred and serviced by FHN, as well as MSR related to loans serviced by FHN and transferred by others, are discussed further in Note 6 - Mortgage Servicing Rights.
	The sensitivity of the fair value of all retained or purchased MSR to immediate 10 percent and 20 percent adverse changes in assumptions on December 31, 2013 and 2012, are as follows:

	Amounts represent market participant based assumptions.
	The sensitivity of the fair value of other retained interests to immediate 10 percent and 20 percent adverse changes in assumptions on December 31, 2013 and 2012, are as follows:
			31-Dec-13								31-Dec-12
			Excess								Excess

	(Dollars in thousands)		IO				PO				IO				PO

	These sensitivities are hypothetical and should not be considered predictive of future performance. As the figures indicate, changes in fair value based on a 10 percent variation in assumptions cannot necessarily be extrapolated because the relationship between the change in assumption and the change in fair value may not be linear. Also, the effect on the fair value of the retained interest caused by a particular assumption variation is calculated independently from all other assumption changes. In reality, changes in one factor may result in changes in another, which might magnify or mitigate the sensitivities. Furthermore, the estimated fair values, as disclosed, should not be considered indicative of future earnings on these assets.
	Prepayment rates and credit spreads (part of the discount rate) are significant unobservable inputs used in the fair value measurement of FHN's MSR, principal only strips and excess interest IO. Cost to service and earnings on escrow are additional unobservable inputs included in the valuation of MSR. Increases in prepayment rates, credit spreads and costs to service in isolation would result in significantly lower fair value measurements for the associated assets. Conversely, decreases in prepayment rates, credit spreads and costs to service in isolation would result in significantly higher fair value measurements for the associated assets. An increase/(decrease) in earnings on escrow in isolation would be accompanied by an increase/(decrease) in the value of the related MSR. Generally, when market interest rates decline and other factors favorable to prepayments occur, there is a corresponding increase in prepayment rates as customers are expected to refinance existing mortgages under more favorable interest rate terms. Generally, changes in discount rates directionally mirror the changes in market interest rates. In third quarter 2013, FHN agreed to sell substantially all its remaining legacy mortgage servicing. Sales commenced in fourth quarter 2013 and were substantially completed in first quarter 2014. FHN used the price in the definitive agreement, as adjusted for the portion of pricing that was not specific to the MSR and excess interest, as a third-party pricing source in the valuation of the remaining servicing assets as of December 31, 2013.
	Prior to the contracted servicing sale, the MSR Hedging Working Group reviewed the overall assessment of the estimated fair value of MSR and excess interests weekly and was responsible for approving the critical assumptions used by management to determine the estimated fair value of FHN's retained interests. In addition, this working group reviewed the source of significant changes to the carrying values each quarter and was responsible for hedges and approving hedging strategies during periods when the MSR was hedged. Hedges were terminated upon execution of the definitive agreement to sell servicing. Subsequent to the contracted servicing sale, FHN's Corporate Accounting monitors sale activity and changes in the fair value of MSR and excess interest monthly.
	Prior to the contracted servicing sale, FHN also engaged in a process referred to as “price discovery” on a quarterly basis to assess the reasonableness of the estimated fair value of retained interests. Price discovery was conducted through a process of obtaining the following information: (1) quarterly informal (and an annual formal) valuation of the servicing portfolio by prominent independent mortgage-servicing brokers and (2) a collection of surveys and benchmarking data made available by independent third parties that include peer participants in the mortgage banking business. Although there was no single source of market information that could be relied upon to assess the fair value of MSR or excess interests, FHN reviewed all information obtained during price discovery to determine whether the estimated fair value of MSR was reasonable when compared to market information.
	For the years ended December 31, 2013, 2012 and 2011, cash flows received and paid related to loan sales and securitizations were as follows:
	(Dollars in thousands)	2013			2012			2011

	Amounts represent real estate residential loans in FHN's portfolio, held-for-sale, and loans that have been transferred in proprietary securitizations and whole loan sales in which FHN has a retained interest other than servicing rights. Also includes $39.4 million and $5.8 billion of loans transferred to GSEs with any type of retained interest on December 31, 2013 and 2012, respectively.
	December 31, 2013 and 2012, includes $.7 billion where the principal amount is 90 days or more past due or nonaccrual. Included in these amounts are $39.8 million and $36.6 million of GNMA guaranteed mortgages on December 31, 2013 and 2012, respectively.
	No delinquency or net credit loss data is provided for the loans transferred to FNMA or FHLMC because these agencies retain credit risk. See Note 18 - Contingencies and Other Disclosures for discussion related to repurchase obligations for loans transferred to GSEs or private investors.

Note 24 – Variable Interest Entities

ASC 810 defines a VIE as an entity where the equity investors, as a group, lack either (1) the power through voting rights, or similar rights, to direct the activities of an entity that most significantly impact the entity's economic performance, (2) the obligation to absorb the expected losses of the entity, (3) the right to receive the expected residual returns of the entity, or (4) when the equity investors, as a group, do not have sufficient equity at risk for the entity to finance its activities by itself. A variable interest is a contractual ownership, or other interest, that fluctuates with changes in the fair value of the VIE's net assets exclusive of variable interests. Under ASC 810, as amended, a primary beneficiary is required to consolidate a VIE when it has a variable interest in a VIE that provides it with a controlling financial interest. For such purposes, the determination of whether a controlling financial interest exists is based on whether a single party has both the power to direct the activities of the VIE that most significantly impact the VIE's economic performance and the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant.

Consolidated Variable Interest Entities

FHN holds variable interests in proprietary residential mortgage securitization trusts it established prior to 2008 as a source of liquidity for its mortgage banking and consumer lending operations. Except for recourse due to breaches of representations and warranties made by FHN in connection with the sale of the loans to the trusts, the creditors of the trusts hold no recourse to the assets of FHN. Based on their restrictive nature, the trusts are considered VIEs as the holders of equity at risk do not have the power through voting rights or similar rights to direct the activities that most significantly impact the trusts' economic performance. In situations where the retention of MSR and other retained interests, including residual interests and subordinated bonds, results in FHN potentially absorbing losses or receiving benefits that are significant to the trusts, FHN is considered the primary beneficiary, as it is also assumed to have the power as servicer to most significantly impact the activities of such VIEs. Consolidation of the trusts results in the recognition of the trusts' proceeds as restricted borrowings since the cash flows on the securitized loans can only be used to settle the obligations due to the holders of the trusts' securities. In third quarter 2013, FHN agreed to sell the servicing related to one of these consolidated securitization trusts. Upon closing of this sale in January 2014, the securitization trust was de-consolidated and prospectively considered a non-consolidated VIE.

Included in the December 31, 2013 balance of consolidated proprietary residential mortgage securitizations is a HELOC securitization trust that has entered a rapid amortization period and for which FHN is obligated to provide subordinated funding. During this period, cash payments from borrowers are accumulated to repay outstanding debt securities while FHN continues to make advances to borrowers when they draw on their lines of credit. FHN then transfers the newly generated receivables into the securitization trust and is reimbursed only after other parties in the securitization have received all of the cash flows to which they are entitled. If loan losses requiring draws on the related monoline insurers' policies, which protect bondholders in the securitization, exceed a certain level, FHN may not receive reimbursement for all of the funds advanced to borrowers, as the senior bondholders and the monoline insurers typically have priority for repayment. This securitization trust is currently consolidated by FHN due to FHN's status as the Master Servicer for the securitization and the retention of a significant residual interest. Because the trust is consolidated, amounts funded from monoline insurance policies are considered as additional restricted term borrowings in FHN's Consolidated Statements of Condition.

FHN has established certain rabbi trusts related to deferred compensation plans offered to its employees. FHN contributes employee cash compensation deferrals to the trusts and directs the underlying investments made by the trusts. The assets of these trusts are available to FHN's creditors only in the event that FHN becomes insolvent. These trusts are considered VIEs as there is no equity at risk in the trusts since FHN provided the equity interest to its employees in exchange for services rendered. FHN is considered the primary beneficiary of the rabbi trusts as it has the power to direct the activities that most significantly impact the economic performance of the rabbi trusts through its ability to direct the underlying investments made by the trusts. Additionally, FHN could potentially receive benefits or absorb losses that are significant to the trusts due to its right to receive any asset values in excess of liability payoffs and its obligation to fund any liabilities to employees that are in excess of a rabbi trust's assets.

Nonconsolidated Variable Interest Entities

Low Income Housing Partnerships. First Tennessee Housing Corporation (“FTHC”), a wholly-owned subsidiary of FTBNA, makes equity investments as a limited partner in various partnerships that sponsor affordable housing projects utilizing the Low Income Housing Tax Credit (“LIHTC”) pursuant to Section 42 of the Internal Revenue Code. The purpose of these investments is to achieve a satisfactory return on capital and to support FHN's community reinvestment initiatives. The activities of the limited partnerships include the identification, development, and operation of multi-family housing that is leased to qualifying residential tenants generally within FHN's primary geographic region. LIHTC partnerships are considered VIEs as FTHC, the holder of the equity investment at risk, does not have the ability to direct the activities that most significantly affect the performance of the entity through voting rights or similar rights. FTHC could absorb losses that are significant to the LIHTC partnerships as it has a risk of loss for its initial capital contributions and funding commitments to each partnership. The general partners are considered the primary beneficiaries as managerial functions give them the power to direct the activities that most significantly impact the partnerships' economic performance and the general partners are exposed to all losses beyond FTHC's initial capital contributions and funding commitments.

New Market Tax Credit LLCs. First Tennessee New Markets Corporation (“FTNMC”), a wholly-owned subsidiary of FTBNA, makes equity investments through wholly-owned subsidiaries as a limited member in various limited liability companies (“LLCs”) that sponsor community development projects utilizing the New Market Tax Credit (“NMTC”) pursuant to Section 45 of the Internal Revenue Code. The purpose of these investments is to achieve a satisfactory return on capital and to support FHN's community reinvestment initiatives. The activities of the LLCs include providing investment capital for low-income communities within FHN's primary geographic region. A portion of the funding of FTNMC's investment in a NMTC LLC is obtained via a loan from an unrelated third-party that is typically a community development enterprise. The NMTC LLCs are considered VIEs as FTNMC, the holder of the equity investment at risk, does not have the ability to direct the activities that most significantly affect the performance of the entity through voting rights or similar rights. While FTNMC could absorb losses that are significant to the NMTC LLCs as it has a risk of loss for its initial capital contributions, the managing members are considered the primary beneficiaries as managerial functions give them the power to direct the activities that most significantly impact the NMTC LLCs' economic performance and the managing members are exposed to all losses beyond FTNMC's initial capital contributions.

Small Issuer Trust Preferred Holdings. FTBNA holds variable interests in trusts which have issued mandatorily redeemable preferred capital securities (“trust preferreds”) for smaller banking and insurance enterprises. FTBNA has no voting rights for the trusts' activities. The trusts' only assets are junior subordinated debentures of the issuing enterprises. The creditors of the trusts hold no recourse to the assets of FTBNA. These trusts meet the definition of a VIE as the holders of the equity investment at risk do not have the power through voting rights, or similar rights, to direct the activities that most significantly impact the trusts' economic performance. Based on the nature of the trusts' activities and the size of FTBNA's holdings, FTBNA could potentially receive benefits or absorb losses that are significant to the trusts regardless of whether a majority of a trust's securities are held by FTBNA. However, since FTBNA is solely a holder of the trusts' securities, it has no rights which would give it the power to direct the activities that most significantly impact the trusts' economic performance and thus it is not considered the primary beneficiary of the trusts. FTBNA has no contractual requirements to provide financial support to the trusts.

On-Balance Sheet Trust Preferred Securitization. In 2007, FTBNA executed a securitization of certain small issuer trust preferreds for which the underlying trust meets the definition of a VIE as the holders of the equity investment at risk do not have the power through voting rights, or similar rights, to direct the activities that most significantly impact the entity's economic performance. FTBNA could potentially receive benefits or absorb losses that are significant to the trust based on the size and priority of the interests it retained in the securities issued by the trust. However, since FTBNA did not retain servicing or other decision making rights, FTBNA is not the primary beneficiary as it does not have the power to direct the activities that most significantly impact the trust's economic performance. Accordingly, FTBNA has accounted for the funds received through the securitization as a term borrowing in its Consolidated Statements of Condition. FTBNA has no contractual requirements to provide financial support to the trust.

Proprietary Trust Preferred Issuances. FHN has previously issued junior subordinated debt to First Tennessee Capital II (“Capital II”). Capital II is considered a VIE as FHN's capital contributions to this trust are not considered “at risk” in evaluating whether the holders of the equity investments at risk in the trust have the power through voting rights, or similar rights, to direct the activities that most significantly impact the entity's economic performance. FHN is not the trust's primary beneficiary as FHN's capital contributions to the trust are not considered variable interests as they are not “at risk”. Consequently, Capital II is not consolidated by FHN.

Proprietary Residential Mortgage Securitizations. FHN holds variable interests in proprietary residential mortgage securitization trusts it established prior to 2008 as a source of liquidity for its mortgage banking operations. Except for recourse due to breaches of representations and warranties made by FHN in connection with the sale of the loans to the trusts, the creditors of the trusts hold no recourse to the assets of FHN. Additionally, FHN has no contractual requirements to provide financial support to the trusts. Based on their restrictive nature, the trusts are considered VIEs as the holders of equity at risk do not have the power through voting rights, or similar rights, to direct the activities that most significantly impact the trusts' economic performance. While FHN is assumed to have the power as servicer to most significantly impact the activities of such VIEs in situations where FHN does not have the ability to participate in significant portions of a securitization trust's cash flows, it is not considered the primary beneficiary of the trust. Therefore, these trusts are not consolidated by FHN. Upon closing of the servicing sales agreed to in third quarter 2013, FHN's interests in these securitizations will decline substantially.

Agency Residential Mortgage Securitizations. During fourth quarter 2013, FHN completed the sale of substantially all servicing for Agency securitizations resulting in the de-recognition of its interests in these trusts.

Prior to third quarter 2008, FHN transferred first lien mortgages that were included in Agency-sponsored securitizations and retained MSR and in certain situations various other interests. Except for recourse due to breaches of standard representations and warranties made by FHN in connection with the sale of the loans to the trusts, the creditors of the trusts held no recourse to the assets of FHN. Additionally, FHN had no contractual requirements to provide financial support to the trusts. The Agencies' or designated third parties' status as Master Servicer and the rights they hold consistent with their guarantees on the securities issued provide them with the power to direct the activities that most significantly impact the trusts' economic performance. Thus, such trusts were not consolidated by FHN as it was not considered the primary beneficiary even in situations where it could potentially receive benefits or absorb losses that were significant to the trusts.

In relation to certain Agency securitizations, FHN purchased the servicing rights on securitized loans from the loan originator and held other retained interests. Based on their restrictive nature, the trusts meet the definition of a VIE since the holders of the equity investments at risk do not have the power through voting rights, or similar rights, to direct the activities that most significantly impact the trusts' economic performance. As the Agencies serve as Master Servicer for the securitized loans and hold rights consistent with their guarantees on the securities issued, they have the power to direct the activities that most significantly impact the trusts' economic performance. Thus, FHN was not considered the primary beneficiary even in situations where it could potentially receive benefits or absorb losses that were significant to the trusts. FHN had no contractual requirements to provide financial support to the trusts.

On-Balance Sheet Consumer Loan Securitizations. FHN holds variable interests in proprietary residential mortgage securitization trusts it established prior to 2008 as a source of liquidity for its consumer lending operations. Except for recourse due to breaches of representations and warranties made by FHN in connection with the sale of the loans to the trusts, the creditors of the trusts hold no recourse to the assets of FHN. Based on their restrictive nature, the trusts are considered VIEs as the holders of equity at risk do not have the power through voting rights or similar rights to direct the activities that most significantly impact the trusts' economic performance. The nonconsolidated proprietary residential mortgage securitizations as of December 31, 2013, consist of two HELOC securitization trusts that have entered a rapid amortization period and for which FHN is obligated to provide subordinated funding. These securitization trusts are not consolidated by FHN as it is not the Master Servicer for the securitizations. FHN's holding of a unilateral call right to reclaim specific assets in the trusts precludes sale accounting for the related securitization transactions. Thus, even though FHN is not the Master Servicer, the related transactions are accounted for as secured borrowings, with the associated loans and secured debt remaining within FHN's Consolidated Financial Statements.

Holdings & Short Positions in Agency Mortgage-Backed Securities. FHN holds securities issued by various Agency securitization trusts. Based on their restrictive nature, the trusts meet the definition of a VIE since the holders of the equity investments at risk do not have the power through voting rights, or similar rights, to direct the activities that most significantly impact the entities' economic performance. FHN could potentially receive benefits or absorb losses that are significant to the trusts based on the nature of the trusts' activities and the size of FHN's holdings. However, FHN is solely a holder of the trusts' securities and does not have the power to direct the activities that most significantly impact the trusts' economic performance, and is not considered the primary beneficiary of the trusts. FHN has no contractual requirements to provide financial support to the trusts.

Commercial Loan Troubled Debt Restructurings. For certain troubled commercial loans, FTBNA restructures the terms of the borrower's debt in an effort to increase the probability of receipt of amounts contractually due. Following a troubled debt restructuring, the borrower entity typically meets the definition of a VIE as the initial determination of whether an entity is a VIE must be reconsidered as events have proven that the entity's equity is not sufficient to permit it to finance its activities without additional subordinated financial support or a restructuring of the terms of its financing. As FTBNA does not have the power to direct the activities that most significantly impact such troubled commercial borrowers' operations, it is not considered the primary beneficiary even in situations where, based on the size of the financing provided, FTBNA is exposed to potentially significant benefits and losses of the borrowing entity. FTBNA has no contractual requirements to provide financial support to the borrowing entities beyond certain funding commitments established upon restructuring of the terms of the debt that allows for preparation of the underlying collateral for sale.

Managed Discretionary Trusts. FHN serves as manager over certain discretionary trusts, for which it makes investment decisions on behalf of the trusts' beneficiaries in return for a reasonable management fee. The trusts meet the definition of a VIE since the holders of the equity investments at risk do not have the power, through voting rights or similar rights, to direct the activities that most significantly impact the entities' economic performance. The management fees FHN receives are not considered variable interests in the trusts as all of the requirements related to permitted levels of decision maker fees are met. Therefore, the VIEs are not consolidated by FHN as it is not the trusts' primary beneficiary. FHN has no contractual requirements to provide financial support to the trusts.

Derivatives [Abstract]	'
Derivatives	'
	Note 25 – Derivatives
	In the normal course of business, FHN utilizes various financial instruments (including derivative contracts and credit-related agreements) through its capital markets and risk management operations, as part of its risk management strategy and as a means to meet customers' needs. Additionally, FHN used derivatives to hedge MSR, but such hedges were terminated in third quarter 2013 when FHN entered into an agreement to sell substantially all MSR. These instruments are subject to credit and market risks in excess of the amount recorded on the balance sheet as required by GAAP. The contractual or notional amounts of these financial instruments do not necessarily represent credit or market risk. However, they can be used to measure the extent of involvement in various types of financial instruments. Controls and monitoring procedures for these instruments have been established and are routinely reevaluated. The Asset/Liability Committee (“ALCO”) monitors the usage and effectiveness of these financial instruments.
	Credit risk represents the potential loss that may occur if a party to a transaction fails to perform according to the terms of the contract. The measure of credit exposure is the replacement cost of contracts with a positive fair value. FHN manages credit risk by entering into financial instrument transactions through national exchanges, primary dealers or approved counterparties, and using mutual margining and master netting agreements whenever possible to limit potential exposure. FHN also maintains collateral posting requirements with certain counterparties to limit credit risk. On December 31, 2013 and 2012, respectively, FHN had $115.2 million and $182.6 million of cash receivables and $80.6 million and $128.3 million of cash payables related to collateral posting under master netting arrangements, inclusive of collateral posted related to contracts with adjustable collateral posting thresholds and over collateralized positions, with derivative counterparties. With exchange-traded contracts, the credit risk is limited to the clearinghouse used. For non-exchange traded instruments, credit risk may occur when there is a gain in the fair value of the financial instrument and the counterparty fails to perform according to the terms of the contract and/or when the collateral proves to be of insufficient value. See additional discussion regarding master netting agreements and collateral posting requirements later in this note under the heading “Master Netting and Similar Agreements.” Market risk represents the potential loss due to the decrease in the value of a financial instrument caused primarily by changes in interest rates or the prices of debt instruments. FHN manages market risk by establishing and monitoring limits on the types and degree of risk that may be undertaken. FHN continually measures this risk through the use of models that measure value-at-risk and earnings-at-risk.
	Derivative Instruments. FHN enters into various derivative contracts both in a dealer capacity, to facilitate customer transactions, and as a risk management tool. Where contracts have been created for customers, FHN enters into transactions with dealers to offset its risk exposure. Contracts with dealers that require central clearing are novated to a clearing agent who becomes FHN's counterparty. Derivatives are also used as a risk management tool to hedge FHN's exposure to changes in interest rates or other defined market risks.
	Forward contracts are over-the-counter contracts where two parties agree to purchase and sell a specific quantity of a financial instrument at a specified price, with delivery or settlement at a specified date. Futures contracts are exchange-traded contracts where two parties agree to purchase and sell a specific quantity of a financial instrument at a specified price, with delivery or settlement at a specified date. Interest rate option contracts give the purchaser the right, but not the obligation, to buy or sell a specified quantity of a financial instrument, at a specified price, during a specified period of time. Caps and floors are options that are linked to a notional principal amount and an underlying indexed interest rate. Interest rate swaps involve the exchange of interest payments at specified intervals between two parties without the exchange of any underlying principal. Swaptions are options on interest rate swaps that give the purchaser the right, but not the obligation, to enter into an interest rate swap agreement during a specified period of time.
	Legacy Mortgage Servicing Operations
	Retained Interests
	FHN revalues MSR to current fair value each month with changes in fair value included in servicing income in Mortgage banking noninterest income on the Consolidated Statements of Income. In third quarter 2013, in conjunction with the agreement to sell legacy mortgage servicing, FHN removed all hedges associated with MSR and interest-only securities. FHN hedged the MSR to minimize the effects of loss in value of MSR associated with increased prepayment activity that generally results from declining interest rates. In a rising interest rate environment, the value of the MSR generally will increase while the value of the hedge instruments will decline. FHN entered into interest rate contracts (potentially including swaps, swaptions, and mortgage forward purchase contracts) to hedge against the effects of changes in fair value of its MSR. Substantially all capitalized MSR were hedged for economic purposes.
	FHN utilized derivatives as an economic hedge (potentially including swaps, swaptions, and mortgage forward purchase contracts) to protect the value of its interest-only securities that change in value inversely to the movement of interest rates. Interest-only securities are included in Trading securities on the Consolidated Statements of Condition. Changes in the fair value of these derivatives and the hedged interest-only securities are recognized currently in earnings in Mortgage banking noninterest income as a component of servicing income on the Consolidated Statements of Income.
	The following table summarizes FHN’s derivatives associated with legacy mortgage servicing activities as of and for the years ended December 31, 2013 and 2012:

	Capital Markets
	Capital markets trades U.S. Treasury, U.S. Agency, mortgage-backed, corporate and municipal fixed income securities, and other securities principally for distribution to customers. When these securities settle on a delayed basis, they are considered forward contracts. Capital markets also enters into interest rate contracts, including caps, swaps, and floors, for its customers. In addition, capital markets enters into futures and option contracts to economically hedge interest rate risk associated with a portion of its securities inventory. These transactions are measured at fair value, with changes in fair value recognized currently in Capital markets noninterest income. Related assets and liabilities are recorded on the Consolidated Statements of Condition as Derivative assets and Derivative liabilities. The FTN Financial Risk Committee and the Credit Risk Management Committee collaborate to mitigate credit risk related to these transactions. Credit risk is controlled through credit approvals, risk control limits, and ongoing monitoring procedures. Total trading revenues were $231.9 million and $307.6 million for the years ended December 31, 2013 and 2012, respectively. Total revenues are inclusive of both derivative and non-derivative financial instruments, and are included in Capital markets noninterest income.

	Interest Rate Risk Management
	FHN's ALCO focuses on managing market risk by controlling and limiting earnings volatility attributable to changes in interest rates. Interest rate risk exists to the extent that interest-earning assets and interest-bearing liabilities have different maturity or repricing characteristics. FHN uses derivatives, including swaps, caps, options, and collars, that are designed to moderate the impact on earnings as interest rates change. Interest paid or received for swaps utilized by FHN to hedge the fair value of long term debt was recognized as an adjustment of the interest expense of the liabilities whose risk is being managed. FHN's interest rate risk management policy is to use derivatives to hedge interest rate risk or market value of assets or liabilities, not to speculate. In addition, FHN has entered into certain interest rate swaps and caps as a part of a product offering to commercial customers that includes customer derivatives paired with offsetting market instruments that, when completed, are designed to mitigate interest rate risk. These contracts do not qualify for hedge accounting and are measured at fair value with gains or losses included in current earnings in Noninterest expense on the Consolidated Statements of Income.
	FHN has entered into pay floating, receive fixed interest rate swaps to hedge the interest rate risk of certain term borrowings totaling $554.0 million and $904.0 million on December 31, 2013 and 2012, respectively. These swaps have been accounted for as fair value hedges under the shortcut method. The balance sheet amount of these swaps was $40.2 million and $71.0 million in Derivative assets on December 31, 2013 and 2012, respectively.
	FHN has designated a derivative transaction in a hedging strategy to manage interest rate risk on its $500 million noncallable senior debt maturing in December 2015. This derivative qualifies for hedge accounting under ASC 815-20 using the long-haul method. FHN entered into a pay floating, receive fixed interest rate swap to hedge the interest rate risk on this debt. The balance sheet amount of this swap was $18.0 million and $26.9 million in Derivative assets as of December 31, 2013 and 2012, respectively. There was no ineffectiveness related to this hedge.
	FHN designates derivative transactions in hedging strategies to manage interest rate risk on subordinated debt related to its trust preferred securities. These qualify for hedge accounting under ASC 815-20 using the long-haul method. FHN hedges the interest rate risk of the subordinated debt totaling $200 million using pay floating, receive fixed interest rate swaps. The balance sheet amount of these swaps was $24.9 million and $2.7 million in Derivative liabilities as of December 31, 2013 and 2012, respectively. There was no ineffectiveness related to these hedges. In April and October 2012, the counterparty called the swaps associated with the $200 million of subordinated debt. FHN discontinued hedge accounting and the cumulative basis adjustments to the associated subordinated debt are being amortized as an adjustment to interest expense over its remaining term. FHN entered into a new interest rate swap to hedge the interest rate risk associated with this debt.

FHN hedges held-to-maturity trust preferred loans with a principal balance of $6.5 million and $56.8 million as of December 31, 2013 and 2012, respectively, which have an initial fixed rate term before conversion to a floating rate. FHN has entered into pay fixed, receive floating interest rate swaps to hedge the interest rate risk associated with this initial term. These hedge relationships qualify as fair value hedges under ASC 815-20. The impact of these swaps was $1.1 million and $2.0 million in Derivative liabilities on the Consolidated Statements of Condition as of December 31, 2013 and 2012, respectively. Interest paid or received for these swaps was recognized as an adjustment of the interest income of the assets whose risk is being hedged. Basis adjustments remaining at the end of the hedge term are being amortized as an adjustment to interest income over the remaining life of the loans. Gains or losses are included in Other income and commissions on the Consolidated Statements of Income.

Other Derivatives
In conjunction with the sales of a portion of its Visa Class B shares, FHN and the purchaser entered into derivative transactions whereby FHN will make or receive cash payments whenever the conversion ratio of the Visa Class B shares into Visa Class A shares is adjusted. As of December 31, 2013, the derivative liabilities associated with the sales of Visa Class B shares were $2.9 million compared to $2.2 million as of December 31, 2012. See the Visa Matters section of Note 18 – Contingencies and Other Disclosures for more information regarding FHN's Visa shares.
FHN utilizes cross currency swaps and cross currency interest rate swaps to economically hedge its exposure to foreign currency risk and interest rate risk associated with non-U.S. dollar denominated loans. As of December 31, 2013 and 2012, these loans were valued at $.6 million. As of December 31, 2013 and 2012, the balance sheet amount and the gains/losses associated with these derivatives were not material.
Master Netting and Similar Agreements
As previously discussed, FHN uses master netting agreements, mutual margining agreements and collateral posting requirements to minimize credit risk on derivative contracts. Master netting and similar agreements are used when counterparties have multiple derivatives contracts that allow for a “right of setoff,” meaning that a counterparty may net offsetting positions and collateral with the same counterparty under the contract to determine a net receivable or payable. The following discussion provides an overview of these arrangements which may vary due to the derivative type and market in which a derivative transaction is executed.
Interest rate derivatives are subject to agreements consistent with those of the International Swap and Derivatives Association (“ISDA”). Currently, all interest rate derivative contracts are entered into as over-the-counter transactions and collateral posting requirements are based on the net asset or liability position with each respective counterparty. For contracts that require central clearing, novation to a central counter party clearinghouse occurs and collateral is posted. Cash collateral received (posted) for interest rate derivatives is recognized as a liability (asset) on FHN's balance sheet.
Interest rate derivatives with customers that are smaller financial institutions typically require posting of collateral by the counterparty to FHN. This collateral is subject to a threshold with daily adjustments based upon changes in the level or fair value of the derivative position. Positions and related collateral can be netted in the event of default. Collateral pledged by a counterparty is typically cash or securities. The securities pledged as collateral are not recognized within FHN's Consolidated Statements of Condition. Interest rate derivatives associated with lending arrangements share the collateral with the related loan(s). The derivative and loan positions may be netted in the event of default. For disclosure purposes, the entire collateral amount is allocated to the loan.
Interest rate derivatives with larger financial institutions entered into prior to required central clearing typically contain provisions whereby the collateral posting thresholds under the agreements adjust based on the credit ratings of both counterparties. If the credit rating of FHN and/or FTBNA is lowered, FHN could be required to post additional collateral with the counterparties. Conversely, if the credit rating of FHN and/or FTBNA is increased, FHN could have collateral released and be required to post less collateral in the future. Also, if a counterparty's credit ratings were to decrease, FHN and/or FTBNA could request the posting of additional collateral; whereas if a counterparty's credit ratings were to increase, the counterparty could request the release of excess collateral. Collateral for these arrangements is adjusted daily based on changes in the net fair value position with each counterparty.
The net fair value, determined by individual counterparty, of all derivative instruments with adjustable collateral posting thresholds was $119.0 million of assets and $100.3 million of liabilities on December 31, 2013, and $221.2 million of assets and $172.3 million of liabilities on December 31, 2012. As of December 31, 2013 and 2012, FHN had received collateral of $196.4 million and $260.8 million and posted collateral of $105.9 million and $173.4 million, respectively, in the normal course of business related to these agreements.
Certain agreements entered into prior to required central clearing also contain accelerated termination provisions, inclusive of the right of offset, if a counterparty's credit rating falls below a specified level. If a counterparty's debt rating (including FHN's and FTBNA's) were to fall below these minimums, these provisions would be triggered, and the counterparties could terminate the agreements and request immediate settlement of all derivative contracts under the agreements. The net fair value, determined by individual counterparty, of all derivative instruments with credit-risk-related contingent accelerated termination provisions was $119.0 million of assets and $30.1 million of liabilities on December 31, 2013, and $221.1 million of assets and $38.4 million of liabilities on December 31, 2012. As of December 31, 2013 and 2012, FHN had received collateral of $196.4 million and $260.8 million and posted collateral of $39.4 million and $43.9 million, respectively, in the normal course of business related to these contracts.
Capital Markets buys and sells various types of securities for its customers. When these securities settle on a delayed basis, they are considered forward contracts, and are generally not subject to master netting agreements. Forwards purchased and sold through legacy mortgage banking activities typically consisted of mortgage to be announced ("TBA") trades for which FHN utilized a clearinghouse for settlement. In the event of default, all open positions can be offset. For futures and options, FHN transacts through a third party, and the transactions are subject to margin and collateral maintenance requirements. In the event of default, open positions can be offset along with the associated collateral.
For this disclosure, FHN considers the impact of master netting and other similar agreements which allow FHN to settle all contracts with a single counterparty on a net basis and to offset the net derivative asset or liability position with the related securities and cash collateral. The application of the collateral cannot reduce the net derivative asset or liability position below zero, and therefore any excess collateral is not reflected in the tables below.

	Note 26 –Master Netting and Similar Agreements - Repurchase, Reverse Repurchase, and Securities Borrowing and Lending Transactions
	For repurchase, reverse repurchase and securities borrowing and lending transactions, FHN and each counterparty have the ability to offset all open positions and related collateral in the event of default. Due to the nature of these transactions, the value of the collateral for each transaction approximates the value of the corresponding receivable or payable. For repurchase agreements within FHN's capital markets' business, transactions are collateralized by securities which are delivered on the settlement date and are maintained throughout the term of the transaction. For FHN's repurchase agreements through banking activities, securities are typically pledged at the time of the transaction and not released until settlement. For asset positions, the collateral is not included on FHN's Consolidated Statements of Condition. For liability positions, securities collateral pledged by FHN is generally represented within FHN's trading or available-for-sale securities portfolios.
	For this disclosure, FHN considers the impact of master netting and other similar agreements that allow FHN to settle all contracts with a single counterparty on a net basis and to offset the net asset or liability position with the related securities collateral. The application of the collateral cannot reduce the net asset or liability position below zero, and therefore any excess collateral is not reflected in the tables below.

Restructuring And Related Activities [Abstract]	'
Restructuring, Repositioning, And Efficiency	'
	Note 27 – Restructuring, Repositioning, and Efficiency
	Beginning in 2007, FHN conducted a company-wide review of business practices with the goal of improving its overall profitability and productivity. Such reviews continue throughout the organization. Since 2007, in order to redeploy capital to higher-return businesses, FHN exited or sold non-strategic businesses, eliminated layers of management, and consolidated functional areas.
	Generally, restructuring, repositioning, and efficiency charges related to exited businesses are included in the non-strategic segment while charges related to corporate-driven actions are included in the corporate segment. Net charges recognized by FHN in 2013 related to restructuring, repositioning, and efficiency activities were $5.3 million. Of this amount, $3.8 million represent exit costs that were accounted for in accordance with the Exit of Disposal Cost Obligations Topic of the FASB Accounting Standards Codification (“ASC 420”). Significant expenses recognized in 2013 resulted from the following actions:
	Severance and other employee costs of $3.7 million primarily related to efficiency initiatives within corporate and bank services functions which are classified as Employee compensation, incentives, and benefits within noninterest expense.
	Expense of $2.2 million related to estimated costs for obligations associated with a definitive agreement to sell substantially all remaining legacy mortgage servicing which is reflected in Mortgage banking income.
	During 2012, FHN recognized a net cost of $24.9 million related to restructuring, repositioning, and efficiency activities. Of this amount, $23.1 million represent exit costs that were accounted for in accordance with ASC 420. Significant expenses recognized in 2012 resulted from the following actions:
	Severance and other employee costs of $22.9 million primarily related to efficiency initiatives within corporate and bank services functions which are classified as Employee compensation, incentives, and benefits within noninterest expense.
	Expense of $2.6 million related to prior servicing sales which is reflected in Mortgage banking income.
	Net charges recognized by FHN in 2011 related to restructuring, repositioning, and efficiency activities were $26.9 million. Of this amount, $18.6 million represented exit costs that were accounted for in accordance with ASC 420. Significant expenses recognized in 2011 resulted from the following actions:
	Severance and other employee costs of $16.6 million primarily related to efficiency initiatives within corporate and bank services functions which are classified as Employee compensation, incentives, and benefits within noninterest expense.
	Goodwill impairment of $10.1 million related to the contracted sale of FHI which is reflected in Income/(loss) from discontinued operations, net of tax.
	Gain on divestiture of $9.4 million relating to the sale of Msaver which is reflected in Income/(loss) from discontinued operations, net of tax.
	Loss of $9.0 million related to cancellation of a technology services contract which is reflected in All other expense.
	Settlement of the obligations arising from current initiatives will be funded from operating cash flows. The effect of suspending depreciation on assets held-for-sale was immaterial to FHN's results of operations for all periods. Due to the broad nature of the actions being taken, substantially all components of expense have benefited from past efficiency initiatives and are expected to benefit from the current efficiency initiatives.
	Activity in the restructuring and repositioning liability for the years ended December 31, 2013, 2012, and 2011 is presented in the following table, along with other restructuring and repositioning expenses recognized.

	Note 29 – Other Events
	In conjunction with the sale of servicing rights in first quarter 2014, FHN expects to receive payments for approximately $20 million of previously unrecognized servicing fees. These payments are recognized in mortgage banking income when received. Upon completion of its servicing sales in first quarter 2014, FHN anticipates that over $70 million of servicing assets (primarily MSR) and over $200 million of servicing advances will have been derecognized from the Consolidated Statements of Condition.
	Additionally, as part of the continuing wind down of non-strategic operations, FHN anticipates resolving several legacy securitization structures that have historically been included in FHN's financial statements as consolidated VIEs or secured borrowing arrangements. The aggregate effect of these resolution efforts is expected to result in recognition of approximately $5 million in losses in first quarter 2014. This will also result in the removal of approximately $230 million of secured borrowings from FHN's Consolidated Statements of Condition.
	FHN has also initiated transactions in first quarter 2014 that are expected to result in recognition of approximately $6 million of securities gains and approximately $5 million of losses related to a lease abandonment.

Financial_Information_Policy

Financial Information (Policy)	12 Months Ended
	Dec. 31, 2013
Basis Of Accounting	'
	Basis of Accounting. The consolidated 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.
Principles of Consolidation And Basis Of Presentation	'
	Principles of Consolidation and Basis of Presentation. The consolidated financial statements include the accounts of FHN and other entities in which it has a controlling financial interest. Variable Interest Entities (“VIEs”) for which FHN or a subsidiary has been determined to be the primary beneficiary are also consolidated. The assets and liabilities of FHN's consolidated residential mortgage securitization trusts have been parenthetically disclosed on the face of the Consolidated Statements of Condition as restricted in accordance with the presentation requirements of Accounting Standards Codification (“ASC”) 810, as amended, due to the assets being pledged to settle the trusts' obligations and the trusts' security holders having no recourse to FHN. Affiliates for which FHN is not considered the primary beneficiary and in which FHN does not have a controlling financial interest are accounted for by the equity method. These investments are included in other assets, and FHN's proportionate share of income or loss is included in noninterest income. All significant intercompany transactions and balances have been eliminated. For purposes of comparability, certain prior period amounts have been reclassified to conform to current year presentation.
Business Combinations	'
	Business Combinations. FHN accounts for acquisitions as a business combination in accordance with ASC 805, "Business Combinations," which requires acquired assets and liabilities (other than tax balances) to be recorded at fair value. Business combinations are included in the financial statements from the respective dates of acquisition.
Revenue Recognition	'
	Revenue Recognition. FHN derives a significant portion of its revenues from fee-based services. Noninterest income from transaction-based fees is generally recognized when the transactions are completed. Noninterest income from service-based fees is generally recognized over the period in which FHN provides the service.
Deposit Transactions And Cash Management	'
	Deposit Transactions and Cash Management. Deposit transactions include services related to retail and commercial deposit products (such as service charges on checking accounts), cash management products and services such as electronic transaction processing (Automated Clearing House and Electronic Data Interchange), account reconciliation services, cash vault services, lockbox processing, and information reporting to large corporate clients.
Insurance Commissions	'
	Insurance Commissions. Insurance commissions are derived from the sale of insurance products, including acting as an independent agent to provide life, long-term care, and disability insurance.
Trust Services And Investment Management Fees	'
	Trust Services and Investment Management. Trust services and investment management fees include investment management, personal trust, employee benefits, and custodial trust services.
Brokerage, Management Fees and Commissions	'
	Brokerage, Management Fees and Commissions. Brokerage, management fees and commissions include fees for portfolio management, trade commissions, and annuity and mutual fund sales.
Statements of Cash Flows	'
	Statements of Cash Flows. For purposes of these statements, cash and due from banks, federal funds sold, and securities purchased under agreements to resell are considered cash and cash equivalents. Federal funds are usually sold for one-day periods, and securities purchased under agreements to resell are short-term, highly liquid investments.
Trading Activities	'
	Trading Activities. Securities purchased in connection with underwriting or dealer activities (long positions) are carried at fair market value as trading securities. Gains and losses, both realized and unrealized, on these securities are reflected in capital markets noninterest income. Trading liabilities include securities that FHN has sold to other parties but does not own (short positions). FHN is obligated to purchase securities at a future date to cover the short positions. Assets and liabilities for unsettled trades are recorded on the Consolidated Statements of Condition as “Capital markets receivables” or “Capital markets payables.” Beginning in 2013, these balances reflect the netting of certain capital markets receivables and payables, with prior periods revised for comparability. Retained interests from securitizations in the form of excess interest, interest-only and principal-only strips from sales and securitizations of first lien mortgages are recognized at fair value as trading securities with gains and losses, both realized and unrealized, recognized in mortgage banking income. Excess interest represents rights to receive interest from serviced assets that exceed contractually specified rates. Principal-only strips are principal cash flow tranches, and interest-only strips are interest cash flow tranches. Cash receipts and payments are classified in investing activities on the Consolidated Statements of Cash Flows based on the purpose for which such financial assets were retained.
Investment Securities	'
	Investment Securities. Investment securities are reviewed quarterly for possible other-than-temporary impairment (“OTTI”). The review includes an analysis of the facts and circumstances of each individual investment such as the degree of loss, the length of time the fair value has been below cost, the expectation for that security's performance, the creditworthiness of the issuer and FHN's intent and ability to hold the security. Securities that may be sold prior to maturity and equity securities are classified as securities available-for-sale and are carried at fair value. The unrealized gains and losses on securities available-for-sale, including debt securities for which no credit impairment exists, are excluded from earnings and are reported, net of tax, as a component of other comprehensive income within shareholders' equity. Venture capital investments are classified as securities available-for-sale and are carried at fair value with unrealized gains and losses recognized in noninterest income.
	Realized gains and losses for investment securities are determined by the specific identification method and reported in noninterest income. Declines in value judged to be other-than-temporary based on FHN's analysis of the facts and circumstances related to an individual investment, including securities that FHN has the intent to sell, are also determined by the specific identification method, and reported in noninterest income. For impaired debt securities that FHN does not intend to sell and will not be required to sell prior to recovery but for which credit losses exist, the OTTI recognized is separated between the total impairment related to credit losses which is reported in noninterest income, and the impairment related to all other factors which is excluded from earnings and reported, net of tax, as a component of other comprehensive income within shareholders' equity.
	National banks chartered by the federal government are, by law, members of the Federal Reserve System. Each member bank is required to own stock in its regional Federal Reserve Bank ("FRB"). Given this requirement, FRB stock may not be sold, traded, or pledged as collateral for loans. Membership in the Federal Home Loan Bank (“FHLB”) network requires ownership of capital stock. Member banks are entitled to borrow funds from the FHLB and are required to pledge mortgage loans as collateral. Investments in the FHLB are non-transferable and, generally, membership is maintained primarily to provide a source of liquidity as needed.
Securities Purchased under Resale Agreements and Securities Sold under Repurchase Agreements	'
	Securities Purchased under Resale Agreements and Securities Sold under Repurchase Agreements. FHN enters into short-term purchases of securities under agreements to resell which are accounted for as collateralized financings except where FHN does not have an agreement to sell the same or substantially the same securities before maturity at a fixed or determinable price. As of December 31, 2013 and 2012, and for the three years ended December 31, 2013, all of FHN's securities purchased under agreements to resell were recognized as collateralized financings. Securities delivered under these transactions are delivered to either the dealer custody account at the FRB or to the applicable counterparty. Securities sold under agreements to repurchase are offered to cash management customers as an automated, collateralized investment account. Securities sold are also used by the retail/commercial bank to obtain favorable borrowing rates on its purchased funds. As of December 31, 2013 and 2012, all of FHN's securities sold under agreements to repurchase were secured borrowings.
	Collateral is valued daily and FHN may require counterparties to deposit additional securities or cash as collateral, or FHN may return cash or securities previously pledged by counterparties, or FHN may be required to post additional securities or cash as collateral, based on the contractual requirements for these transactions.
	FHN's capital markets business utilizes securities borrowing arrangements as part of its trading operations. Securities borrowing transactions generally require FHN to deposit cash with the securities lender. The amount of cash advanced is recorded within Securities purchased under agreements to resell in the Consolidated Statements of Condition. These transactions are not considered purchases and the securities borrowed are not recognized by FHN. FHN does not conduct securities lending transactions.
Loans Held-for-Sale and Securitization and Residual Interests	'
	Loans Held-for-Sale and Securitization and Residual Interests. Prior to fourth quarter 2008, FHN originated first lien mortgage loans (“the warehouse”) for the purpose of selling them in the secondary market through sales to government sponsored enterprises ("GSEs"), through proprietary securitizations, and to a lesser extent through other whole loan sales. In addition, FHN sold certain of the second lien mortgages and home equity lines of credit (“HELOC”) it produced in the secondary market through securitizations and whole loan sales through third quarter 2007. The majority of the mortgage securitization trusts to which FHN transferred loans remains unconsolidated as FHN is deemed not to be the primary beneficiary based on the interests it retained in the trusts. Under ASC 810, as amended, continual reconsideration of conclusions reached regarding which interest holder is the primary beneficiary of a trust is required. See Note 24 – Variable Interest Entities for additional information regarding FHN's consolidated and nonconsolidated mortgage securitization trusts.
	Loans originated or purchased in which management lacks the intent to hold are included in loans held-for-sale in the Consolidated Statements of Condition. FHN has elected the fair value option on a prospective basis for almost all types of mortgage loans originated for sale purposes. Such loans are carried at fair value, with changes in the fair value of these loans recognized in the mortgage banking noninterest income section of the Consolidated Statements of Income. For mortgage loans originated for sale for which the fair value option is elected, loan origination fees are recorded by FHN when earned and related direct loan origination costs are recognized when incurred. See Note 22 – Fair Value of Assets and Liabilities for additional information. FHN accounts for all mortgage loans held-for-sale which were originated prior to 2008 and for mortgage loans held-for-sale for which fair value accounting was not elected at the lower of cost or market value (“LOCOM”).
	Mortgage loans insured by the Federal Housing Administration (“FHA”) and mortgage loans guaranteed by the Veterans Administration (“VA”) were generally securitized through the Government National Mortgage Association (“GNMA”, "Ginnie Mae", or "Ginnie") programs. Generally, conforming conventional loans were securitized through GSEs such as the Federal National Mortgage Association (“FNMA”, "Fannie Mae", or "Fannie") and the Federal Home Loan Mortgage Corporation (“FHLMC”, "Freddie Mac" or "Freddie"). In addition, FHN completed proprietary securitizations of nonconforming first lien and second lien mortgages and HELOC, which do not conform to the requirements for sale or securitization through government agencies. Most of these securitizations are accounted for as sales; those that do not qualify for sale treatment are accounted for as consolidated VIEs or financing arrangements.
	Interests retained from loan sales, including agency securitizations, include mortgage servicing rights ("MSR") and excess interest. Interests retained from proprietary securitizations include MSR and various financial assets which are included in trading securities. All retained interests, including MSR, are carried at fair value. FHN no longer retains financial interests in loans it transfers to third parties.
Loans	'
	Loans. Loans are stated at principal amounts outstanding, net of unearned income. Interest on loans is recognized on an accrual basis at the applicable interest rate on the principal amount outstanding. Loan origination fees and direct costs as well as premiums and discounts are amortized as level yield adjustments over the respective loan terms. Unamortized net fees or costs are recognized upon early repayment of the loans or charge-off. Loan commitment fees are generally deferred and amortized on a straight-line basis over the commitment period. As required by ASC 310, "Receivables", FHN segregates the loan portfolio into segments and then further disaggregates the portfolio into classes for certain disclosures. 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., loans to bank and insurance-related businesses) portfolio and purchase credit impaired ("PCI") loans. Loans to mortgage companies includes commercial lines of credit to qualified mortgage companies exclusively 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 commercial real estate include income CRE, residential CRE and PCI loans. Retail loan portfolio segments include consumer real estate, permanent mortgage, and the credit card and other segment. 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.
Nonaccrual and Past Due Loans	'
	Nonaccrual and Past Due Loans. Generally, for all portfolio segments and classes other than PCI loans, loans are placed on nonaccrual status if it becomes evident that full collection of principal and interest is at risk, impairment has been recognized as a partial charge-off of principal balance, or on a case-by-case basis if FHN continues to receive payments, but there are atypical loan structures or other borrower-specific issues. The determination of whether a troubled debt restructuring ("TDR") is placed on nonaccrual status generally follows the same internal policies and procedures as other portfolio loans. However, FHN will typically place a consumer real estate loan on nonaccrual status if it is 30 or more days delinquent at the time of modification and is determined to be a TDR, except for residential real estate secured loans discharged in bankruptcy ("discharged bankruptcies") that are placed on nonaccrual, regardless of delinquency status. Additionally, current second liens are placed on nonaccrual status if junior to first liens that are 90 days or more delinquent or have been modified into a troubled debt restructuring.
	For commercial and retail loans within each portfolio segment and class that have been placed on nonaccrual status, accrued but uncollected interest is reversed and charged against interest income when the loan is placed on nonaccrual status. Management may elect to continue the accrual of interest when the estimated net realizable value of collateral is sufficient to recover the principal balance and accrued interest. For all portfolio segments and classes other than PCI loans, interest payments received on nonaccrual and impaired loans are normally applied to principal. Once all principal has been received, additional interest payments are recognized on a cash basis as interest income.
	Generally, commercial and retail loans within each portfolio segment and class that have been placed on nonaccrual status can be returned to accrual status if all principal and interest is current and FHN expects full repayment of the remaining contractual principal and interest, or the asset becomes well-secured and is in the process of collection. Also, loans for which all contractual amounts can reasonably be expected to be repaid (including arrearages) within a prudent period, and repayment has been in accordance with the contractual terms for a sustained period (generally for a minimum of six months) can be returned to accrual status. Larger commercial loan balances (outstanding balances greater than $1 million) that are being returned to accrual status are subject to review by the Credit Risk Assurance Group. Residential real estate loans discharged through Chapter 7 bankruptcy and not reaffirmed by the borrower are not returned to accrual status. For current second liens that have been placed on nonaccrual because the first lien is 90 or more days delinquent or is a TDR, the second lien may be returned to accrual upon pay-off or cure of the first lien.
Charge-offs	'
	Charge-offs. For all commercial and retail loan portfolio segments, all losses of principal are charged to the allowance for loan losses ("ALLL") in the period in which the loan is deemed to be uncollectible. A commercial loan is not deemed uncollectible until after review of the individual credit by FHN's Loan Rehab and Recovery Group.
	For consumer loans, the timing of a full or partial charge-off generally depends on the loan type and delinquency status. Generally, for the consumer real estate and permanent mortgage segments, a loan will be either partially or fully charged-off when it becomes 180 days past due. At this time, if the collateral value does not support foreclosure, balances are fully charged-off and other avenues of recovery are pursued. If the collateral value supports foreclosure, the loan is charged-down to net realizable value of the collateral less estimated costs to sell and is placed on nonaccrual status. Beginning in third quarter 2012, for residential real estate loans discharged in Chapter 7 bankruptcy and not reaffirmed by the borrower, the fair value of the collateral position is assessed at the time FHN is made aware of the discharge. Within the credit card and other portfolio segment, credit cards are normally charged-off upon reaching 180 days past due while other non real estate consumer loans are charged-off upon reaching 120 days past due.
Impaired Loans	'
	Impaired Loans. Impaired loans include nonaccrual commercial loans greater than $1 million and modified consumer and commercial loans that have been classified as a TDR and are individually measured for impairment under the guidance of ASC 310. See Note 4 – Loans for a discussion of methodologies utilized by FHN to measure impairment.
Purchase Credit Impaired Loans Policy	'
	Purchase Credit Impaired Loans. ASC 310-30 “Accounting for Certain Loans or Debt Securities Acquired in a Transfer”, provides guidance for acquired loans that have experienced deterioration of credit quality between origination and the time of acquisition and for which the timely collection of the interest and principal is no longer reasonably assured (“PCI loans”). PCI loans are initially recorded at fair value which is estimated by discounting expected cash flows at acquisition date. The expected cash flows include all contractually expected amounts (including interest) and incorporate an estimate for future expected credit losses, pre-payment assumptions, and yield requirement for a market participant, among other things. To the extent possible, certain PCI loans were aggregated into pools with composite interest rate and cash flows expected to be collected for the pool. Aggregation into loan pools is based on common risk characteristics that include similar credit risk or risk ratings, and one or more predominant risk characteristics. Each PCI pool is accounted for as a single unit.
	Accretable yield is the excess of cash flows expected at acquisition over the initial investment in the loan and is recognized in interest income over the remaining life of the loan, or pool of loans. Nonaccretable difference is the difference between the contractually required payments at acquisition and the cash flows expected to be collected at acquisition. FHN estimates expected cash flows for PCI loans on a quarterly basis. Increases in expected cash flows from the last measurement result in reversal of any nonaccretable difference (or allowance for loan losses to the extent any has previously been recorded) with a prospective positive impact on interest income. Decreases to the expected cash flows result in an increase in the allowance for loan losses through increased provision expense.
	FHN does not report PCI loans as nonperforming loans due to the accretion of interest income. Additionally, PCI loans that have been pooled and subsequently modified will not be reported as troubled debt restructurings since the pool is the unit of measurement.
Allowance for Loan Losses	'
	Allowance for Loan Losses. The ALLL is maintained at a level that management determines is sufficient to absorb estimated probable incurred losses in the loan portfolio. The ALLL is increased by the provision for loan losses and loan recoveries and is decreased by charged-off loans. Reserves are determined in accordance with ASC 450-20-50 "Contingencies - Accruals for Loss Contingencies" and are composed of reserves for commercial loans evaluated based on pools of credit graded loans and reserves for pools of smaller-balance homogeneous retail and commercial loans. The reserve factors applied to these pools are an estimate of probable incurred losses based on management's evaluation of historical net losses from loans with similar characteristics. Additionally, the ALLL includes specific reserves established in accordance with ASC 310-10-35 for loans determined by management to be individually impaired. As of December 31, 2013, the ALLL also included an immaterial reserve associated with purchase credit impaired loans. Management uses analytical models based on loss experience subject to qualitative adjustment to reflect current events, trends, and conditions (including economic considerations and trends) to assess the adequacy of the ALLL as of the end of each reporting period. The nature of the process by which FHN determines the appropriate ALLL requires the exercise of considerable judgment. See Note 4 – Loans for a discussion of FHN's ALLL methodology and a description of the models utilized in the estimation process for the commercial and consumer loan portfolios.
	Key components of the estimation process are as follows: (1) commercial loans determined by management to be individually impaired loans are evaluated individually and specific reserves are determined based on the difference between the outstanding loan amount and the estimated net realizable value of the collateral (if collateral dependent), the present value of expected future cash flows or by observable market prices; (2) individual commercial loans not considered to be individually impaired are segmented based on similar credit risk characteristics and evaluated on a pool basis; (3) reserve rates for the commercial segment are calculated based on historical net charge-offs and are subject to adjustment by management to reflect current events, trends, and conditions (including economic considerations and trends); (4) management's estimate of probable incurred losses reflects the reserve rate applied against the balance of loans in the commercial segment of the loan portfolio; (5) retail loans are generally segmented based on loan type; (6) reserve amounts for each retail portfolio segment are calculated using analytical models based on delinquency trends and net loss experience and are subject to adjustment by management to reflect current events, trends, and conditions (including economic considerations and trends); and (7) the reserve amount for each retail portfolio segment reflects management's estimate of probable incurred losses in the retail segment of the loan portfolio.
	Impairment related to individually impaired loans is measured in accordance with ASC 310-10. For all commercial portfolio segments, commercial TDRs and other individually impaired commercial loans are measured based on the present value of expected future payments discounted at the loan's effective interest rate (“the DCF method”), observable market prices, or for loans that are solely dependent on the collateral for repayment, the estimated fair value of the collateral less estimated costs to sell (net realizable value). Impaired loans also include consumer TDRs. With the exception of discharged bankruptcies which are collateral dependent and charged down to net realizable value, impairment of consumer TDRs is measured using a DCF model. For loans measured using the DCF method or by observable market prices, if the recorded investment in the impaired loan exceeds this amount, a specific allowance is established as a component of the ALLL; however, for impaired collateral-dependent loans FHN generally charges off the full difference between the book value and the estimated net realizable value.
	Future adjustments to the ALLL and methodology may be necessary if economic or other conditions differ substantially from the assumptions used in making the estimates or, if required by regulators, based upon information at the time of their examinations or upon future regulatory guidance. Such adjustments to original estimates, as necessary, are made in the period in which these factors and other relevant considerations indicate that loss levels vary from previous estimates.
Premises And Equipment	'
	Premises and Equipment. Premises and equipment are carried at cost less accumulated depreciation and amortization and include additions that materially extend the useful lives of existing premises and equipment. All other maintenance and repair expenditures are expensed as incurred. Gains and losses on dispositions are reflected in noninterest income and expense.
	Depreciation and amortization are computed on the straight-line method over the estimated useful lives of the assets and are recorded as noninterest expense. Leasehold improvements are amortized over the lesser of the lease periods or the estimated useful lives using the straight-line method. Useful lives utilized in determining depreciation for furniture, fixtures and equipment and buildings are three to fifteen and seven to forty-five years, respectively.
Real Estate Acquired By Foreclosure	'
	Real Estate Acquired by Foreclosure. Real estate acquired by foreclosure consists of properties that have been acquired in satisfaction of debt. These properties are carried at the lower of the outstanding loan amount or estimated fair value less estimated costs to sell the real estate. Losses arising at foreclosure are charged to the appropriate reserve. Properties acquired by foreclosure in compliance with HUD servicing guidelines are included in “Real estate acquired by foreclosure” and are carried at the estimated amount of the underlying government insurance or guarantee. On December 31, 2013, FHN had $25.8 million of these foreclosed properties.
	Required developmental costs associated with foreclosed property under construction are capitalized and included in determining the estimated net realizable value of the property, which is reviewed periodically, and any write-downs are charged against current earnings.
Intangible Assets	'
	Repurchase and Foreclosure Provision. The repurchase and foreclosure provision is the charge to earnings necessary to maintain the liability at a level that reflects management's best estimate of losses associated with the repurchase of loans previously transferred in whole loans sales or securitizations, or make whole requests as of the balance sheet date. See Note 18 – Contingencies and Other Disclosures for discussion related to FHN's obligations to repurchase such loans.
Derivative Financial Instruments	'
	Derivative Financial Instruments. FHN accounts for derivative financial instruments in accordance with ASC 815 which requires recognition of all derivative instruments on the balance sheet as either an asset or liability measured at fair value through adjustments to either accumulated other comprehensive income within shareholders' equity or current earnings. Fair value is defined as the price that would be received to sell a derivative asset or paid to transfer a derivative liability in an orderly transaction between market participants on the transaction date. Fair value is determined using available market information and appropriate valuation methodologies. FHN has elected to present its derivative assets and liabilities gross on the Consolidated Statements of Condition. Amounts of collateral posted or received have not been netted with the related derivatives.
	FHN prepares written hedge documentation, identifying the risk management objective and designating the derivative instrument as a fair value hedge or cash flow hedge as applicable, or as a free-standing derivative instrument entered into as an economic hedge or to meet customers' needs. All transactions designated as ASC 815 hedges must be assessed at inception and on an ongoing basis as to the effectiveness of the derivative instrument in offsetting changes in fair value or cash flows of the hedged item. For a fair value hedge, changes in the fair value of the derivative instrument and changes in the fair value of the hedged asset or liability attributable to the hedged risk are recognized currently in earnings. For a cash flow hedge, changes in the fair value of the derivative instrument, to the extent that it is effective, are recorded in accumulated other comprehensive income and subsequently reclassified to earnings as the hedged transaction impacts net income. Any ineffective portion of a cash flow hedge is recognized currently in earnings. For free-standing derivative instruments, changes in fair values are recognized currently in earnings. See Note 25 – Derivatives for additional information.
	Cash flows from derivative contracts are reported as operating activities on the Consolidated Statements of Cash Flows.
Advertising and Public Relations	'
	Advertising and Public Relations. Advertising and public relations costs are generally expensed as incurred.
Income Taxes	'
	Income Taxes. FHN accounts for income taxes using the asset and liability method pursuant to ASC 740, “Income Taxes,” which requires the recognition of deferred tax assets ("DTAs") and liabilities ("DTLs") for the expected future tax consequences of events that have been included in the financial statements. Under this method, FHN's deferred tax assets and liabilities are determined based on differences between financial statement carrying amounts and the corresponding tax basis of certain assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on DTAs and DTLs is recognized in income in the period that includes the enactment date.
	Additionally, DTAs are subject to a “more likely than not” test to determine whether the full amount of the DTAs should be realized in the financial statements. FHN evaluates the likelihood of realization of the DTA based on both positive and negative evidence available at the time, including (as appropriate) scheduled reversals of DTLs, projected future taxable income, tax planning strategies, and recent financial performance. If the “more likely than not” test is not met, a valuation allowance must be established against the DTA. In the event FHN determines that DTAs are realizable in the future in excess of their net recorded amount, FHN would make an adjustment to the valuation allowance, which would reduce the provision for income taxes.
	FHN's ASC 740 policy is to recognize interest and penalties related to unrecognized tax benefits as a component of income tax expense. Accrued interest and penalties are included within the related tax asset/liability line in the consolidated balance sheet.
	FHN and its eligible subsidiaries are included in a consolidated federal income tax return. FHN files separate returns for subsidiaries that are not eligible to be included in a consolidated federal income tax return. Based on the laws of the applicable state where it conducts business operations, FHN either files consolidated, combined, or separate returns. With few exceptions, FHN is no longer subject to U.S. federal or state and local tax examinations by tax authorities for years before 2009. The Internal Revenue Service (“IRS”) recently completed a limited issue focused examination ("LIFE") for the years ending December 31, 2011 and 2010. All proposed adjustments with respect to examinations of federal returns filed for 2011 and prior years have been settled. FHN is currently under audit in several states.
Earnings per Share	'
	Earnings per Share. Earnings per share is computed by dividing net income or loss available to common shareholders by the weighted average number of common shares outstanding for each period. Diluted earnings per share in net income periods is computed by dividing net income available to common shareholders by the weighted average number of common shares adjusted to include the number of additional common shares that would have been outstanding if the potential dilutive common shares resulting from restricted shares or units and options granted under FHN's equity compensation plans and deferred compensation arrangements had been issued. FHN utilizes the treasury stock method in this calculation. Diluted earnings per share does not reflect an adjustment for potentially dilutive shares in periods in which a net loss available to common shareholders exists.
Equity Compensation	'
	Equity Compensation. FHN accounts for its employee stock-based compensation plans using the grant date fair value of an award to determine the expense to be recognized over the life of the award. For awards with service vesting criteria, expense is recognized using the straight-line method over the requisite service period (generally the vesting period) and is adjusted for anticipated forfeitures. For awards vesting based on a performance measure, anticipated performance is projected to determine the number of awards expected to vest, and the corresponding aggregate expense is adjusted to reflect the elapsed portion of the performance period. The fair value of equity awards with cash payout requirements, as well as awards for which fair value cannot be estimated at grant date, is remeasured each reporting period through vesting date. Performance awards with pre-grant date achievement criteria are expensed over the period from the start of the performance period through the end of the service vesting term. Awards are amortized using the nonsubstantive vesting methodology which requires that expense associated with awards having only service vesting criteria that continue vesting after retirement be recognized over a period ending no later than an employee's retirement eligibility date.
Repurchase and Foreclosure Provision	'
	Repurchase and Foreclosure Provision. The repurchase and foreclosure provision is the charge to earnings necessary to maintain the liability at a level that reflects management's best estimate of losses associated with the repurchase of loans previously transferred in whole loans sales or securitizations, or make whole requests as of the balance sheet date. See Note 18 – Contingencies and Other Disclosures for discussion related to FHN's obligations to repurchase such loans.
Legal Costs	'
	Legal Costs. Generally, legal costs are expensed as incurred.
Contingency Accruals	'
	Contingency Accruals. Contingent liabilities arise in the ordinary course of business, including those related to lawsuits, arbitration, mediation, and other forms of litigation. FHN establishes loss contingency liabilities for matters when loss is both probable and reasonably estimable as prescribed by applicable financial accounting guidance. A liability generally is not established when a loss contingency either is not probable or its amount is not reasonably estimable. If loss for a matter is probable and a range of possible loss outcomes is the best estimate available, accounting guidance generally requires a liability to be established at the low end of the range. Expected recoveries from insurance and indemnification arrangements are recognized if they are considered equally as probable and reasonably estimable as the related loss contingency up to the recognized amount of the estimated loss. Gain contingencies and expected recoveries from insurance and indemnification arrangements in excess of the associated recorded estimated losses are recognized when received. Recognized recoveries are recorded as offsets to the related expense in the Consolidated Statements of Income. The favorable resolution of a gain contingency generally results in the recognition of other income in the Consolidated Statements of Income.
Summary of Accounting Changes	'
	Summary of Accounting Changes. Effective January 1, 2013, FHN adopted the provisions of FASB Accounting Standards Update ("ASU") 2011-11, “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 ASU 2013-02, "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 statements but modifies 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.
	In July 2013, the FASB issued ASU 2013-10, "Derivatives and Hedging: Inclusion of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a Benchmark Interest Rate for Hedge Accounting Purposes." ASU 2013-10 provides guidance on the risks that are permitted to be hedged in a fair value or cash flow hedge. The provisions of ASU 2013-10 permit the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) to be used as a U.S. benchmark interest rate for hedge accounting purposes under ASC 815, in addition to U.S. Treasury rates and the London Interbank Offered Rate ("LIBOR"). The amendments also remove the restriction on using different benchmark rates for similar hedges. The provisions of ASU 2013-10 are effective prospectively for qualifying new or re-designated hedging relationships entered into on or after July 17, 2013. FHN may apply the provisions of ASU 2013-10 to future hedging relationships.
	Effective January 1, 2012, FHN adopted the provisions of FASB ASU 2011-05, “Presentation of Comprehensive Income”. ASU 2011-05 requires that net income and other comprehensive income be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. ASU 2011-05 also provides that regardless of the method used to present comprehensive income, presentation is required on the face of the financial statements of reclassification adjustments for items that are reclassified from other comprehensive income to net income. ASU 2011-05 does not change the current option for entities to present components of other comprehensive income gross or net of the effect of income taxes, provided that such tax effects are presented in the statement in which other comprehensive income is presented or disclosed in the notes to the financial statements. The provisions of ASU 2011-05 are effective for periods beginning after December 15, 2011, with retrospective application to all periods presented in the financial statements required. No transition disclosures are required upon adoption. For interim reporting periods, filers are only required to present total comprehensive income in a single continuous statement or in two consecutive statements. On December 23, 2011, the FASB issued ASU 2011-12, which indefinitely defers the provisions of ASU 2011-05 that require entities to present reclassification adjustments out of accumulated other comprehensive income by component in both the statement in which net income is presented and the statement in which other comprehensive income is presented (for both interim and annual financial statements). Upon adoption of the provisions of ASU 2011-05 and ASU 2011-12 on January 1, 2012, FHN revised its financial statements and disclosures accordingly.
	Effective July 1, 2011, FHN adopted the provisions of FASB ASU 2011-02, “A Creditor's Determination of Whether a Restructuring is a Troubled Debt Restructuring”. ASU 2011-02 provides that a situation in which a market rate is not readily available is an indicator of a troubled debt restructuring, but not a determinative factor, and that an assessment should consider all modified terms of the restructuring when making a final determination regarding a troubled debt restructuring designation. ASU 2011-02 also provides that a modification that results in a temporary or permanent increase to the contractual interest rate cannot be presumed to be a rate that is at or above market. ASU 2011-02 explicitly precludes creditors from using the borrower's effective rate test in ASC 470-60, “Debt – Troubled Debt Restructurings by Debtors” in its evaluation of whether a modification was executed at a market rate. Under the provisions of ASU 2011-02, a borrower that is not currently in default may still be considered to be experiencing financial difficulty when default is probable in the foreseeable future. ASU 2011-02 provides factors that an entity should consider when determining whether a delay in the amount of payments is significant, as insignificant delays in cash flows would not be considered a concession to a borrower under its provisions. Retrospective application to the beginning of the annual period of adoption is required for identification and disclosure purposes, with prospective application for impairment purposes. Disclosure of the total amount of loans and the associated reserves related to those loans that are considered impaired under ASC 310, “Receivables”, as a result of the clarification in guidance is required upon initial application. FHN had previously modified its troubled debt restructuring review process and was already in compliance with the provisions of ASU 2011-02. Therefore, the provisions of ASU 2011-02 had no material effect on FHN's statement of condition, results of operations, cash flows, or required disclosures.
	Effective July 1, 2011, FHN adopted the remaining provisions of FASB ASU 2010-20, “Disclosures about the Credit Quality of Financing Receivables and the Allowance for Credit Losses”, related to the enhanced disclosure requirements for modifications of financing receivables. FHN previously adopted the provisions of ASU 2010-20 for certain disclosures about activity that occurs during a reporting period effective January 1, 2011. Additionally, effective December 31, 2010, FHN adopted the provisions of ASU 2010-20 related to disclosures as of the end of a reporting period, and the amendments to the rollforward of the allowance for credit losses. ASU 2010-20 provides enhanced disclosures related to the credit quality of financing receivables and the allowance for credit losses, and provides that new and existing disclosures should be disaggregated based on how an entity develops its allowance for credit losses and how it manages credit exposures. Under the provisions of ASU 2010-20, additional disclosures required for financing receivables include information regarding the aging of past due receivables, credit quality indicators, and modifications of financing receivables. Comparative disclosures are required only for periods ending subsequent to initial adoption. Upon adoption of the provisions of ASU 2010-20 on September 30, 2011, January 1, 2011, and December 31, 2010, respectively, FHN revised its disclosures accordingly.
	Effective January 1, 2011, FHN adopted the provisions of FASB ASU 2010-06, “Improving Disclosures about Fair Value Measurements”, related to the requirement to provide the activity of purchases, sales, issuances, and settlements related to recurring Level 3 measurements on a gross basis in the Level 3 reconciliation. Effective January 1, 2010, FHN adopted all other provisions of ASU 2010-06. ASU 2010-06 updates ASC 820, “Fair Value Measurements and Disclosures” to require disclosure of significant transfers into and out of Level 1 and Level 2 of the fair value hierarchy, as well as disclosure of an entity's policy for determining when transfers between all levels of the hierarchy are recognized. The updated provisions of ASC 820 also require that fair value measurement disclosures be provided by each “class” of assets and liabilities, and that disclosures providing a description of the valuation techniques and inputs used to measure fair value be included for both recurring and nonrecurring fair value measurements classified as either Level 2 or Level 3. Under ASC 820, as amended, separate disclosure is required in the Level 3 reconciliation of total gains and losses recognized in other comprehensive income. Comparative disclosures are required only for periods ending subsequent to initial adoption. Upon adoption of the amendments to ASC 820 on January 1, 2011, and January 1, 2010, respectively, FHN revised its disclosures accordingly.
Accounting Changes Issued but Not Currently Effective	'
	Accounting Changes Issued but Not Currently Effective. In July 2013, the FASB issued ASU 2013-11, "Income Taxes: Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists." ASU 2013-11 provides guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. Generally, ASU 2013-11 requires that an unrecognized tax benefit should reduce a deferred tax asset (“DTA”) that has been established for a net operating loss (“NOL”), a tax credit carryforward, or other similar tax losses. However, if a filer does not have such carryforwards or similar tax losses at the reporting date, the uncertain tax position should be recorded as a liability. If a filer does have a DTA, but is not required by tax law of the applicable jurisdiction to use the DTA to settle additional taxes from the disallowance of a tax position and that is the filers' intent, the uncertain tax position should be recognized as a liability in that situation as well and not netted with the DTA. The assessment of whether a DTA is available is based on the unrecognized tax benefit and DTA that exist at the reporting date and should be made presuming disallowance of the tax position at the reporting date. The provisions of ASU 2013-11 are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013, with early adoption permitted. The provisions of ASU 2013-11 should be applied prospectively to all unrecognized tax benefits that exist at the effective date. Retrospective application is permitted. FHN does not expect the adoption of the provisions of ASU 2013-11 to have a material effect on FHN's statement of condition, results of operations, or cash flows.
	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, and will be applied retrospectively to all periods presented. Early adoption is permitted. FHN is evaluating the effects of ASU 2014-01 on its portfolio of low income housing investments.
	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 property 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 can elect 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. Early adoption is permitted. FHN is evaluating the requirements of ASU 2014-04 with respect to its current foreclosure accounting practices.

	The following table presents TDRs which re-defaulted during 2013 and 2012 and as to which the modification occurred 12 months or less prior to the re-default. Financing receivables that became classified as TDRs within the previous 12 months and for which there was a payment default during the period are calculated by first identifying TDRs that were in default during the period and then determining whether they were modified within the 12 months prior to the default. For purposes of this disclosure, FHN generally defines payment default as a loan being 30 or more days past due.

Nonrecurring Fair Value Measurements	'
	Nonrecurring Fair Value Measurements
	From time to time, FHN may be required to measure certain other financial assets at fair value on a nonrecurring basis in accordance with GAAP. These adjustments to fair value usually result from the application of LOCOM accounting or write-downs of individual assets. For assets measured at fair value on a nonrecurring basis which were still held on the balance sheet at December 31, 2013, 2012, and 2011, respectively, the following tables provide the level of valuation assumptions used to determine each adjustment, the related carrying value, and the fair value adjustments recorded during the respective periods.
