[1]	Provision/(benefit) for income taxes for consolidated results and the Corporate segment for the three and six months ended June 30, 2017, relative to the prior year periods, was affected by a decline in the effective tax rate in 2017 primarily related to the reversal of the valuation allowance for the deferred tax asset related to its 2012 federal capital loss carryforward based on capital gain transactions initiated in second quarter 2017. See Note 15 – Income Taxes in the Notes to Consolidated Financial Statements on FHN’s Form 10-K for the year ended December 31, 2016, for additional information.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Financial Information	Financial Information Basis of Accounting. The unaudited interim consolidated condensed financial statements of First Horizon National Corporation (“FHN”), including its subsidiaries, have been prepared in conformity with accounting principles generally accepted in the United States of America and follow general practices within the industries in which it operates. This preparation requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. These estimates and assumptions are based on information available as of the date of the financial statements and could differ from actual results. In the opinion of management, all necessary adjustments have been made for a fair presentation of financial position and results of operations for the periods presented. These adjustments are of a normal recurring nature unless otherwise disclosed in this Quarterly Report on Form 10-Q. The operating results for the interim 2017 period are not necessarily indicative of the results that may be expected going forward. For further information, refer to the audited consolidated financial statements in Exhibit 13 to FHN’s Annual Report on Form 10-K for the year ended December 31, 2016 . Summary of Accounting Changes. Effective January 1, 2017, FHN adopted the provisions of Accounting Standards Update (“ASU”) 2016-09, “Improvements to Employee Share-Based Payment Accounting,” which makes several revisions to equity compensation accounting. Under the new guidance all excess tax benefits and deficiencies that occur when an award vests, is exercised, or expires are recognized in income tax expense as discrete period items. Previously, these transactions were typically recorded directly within equity. Consistent with this change, excess tax benefits and deficiencies are no longer included within estimated proceeds when performing the treasury stock method for calculation of diluted earnings per share. Excess tax benefits are also recognized at the time an award is exercised or vests compared to the previous requirement to delay recognition until the deduction reduces taxes payable. The presentation of excess tax benefits in the statement of cash flows shifted to an operating activity from the prior classification as a financing activity. ASU 2016-09 also provides an accounting policy election to recognize forfeitures of awards as they occur when estimating stock-based compensation expense rather than the previous requirement to estimate forfeitures from inception. Further, ASU 2016-09 permits employers to use a net-settlement feature to withhold taxes on equity compensation awards up to the maximum statutory tax rate without affecting the equity classification of the award. Under previous guidance, withholding of equity awards in excess of the minimum statutory requirement resulted in liability classification for the entire award. The related cash remittance by the employer for employee taxes is treated as a financing activity in the statement of cash flows. Transition to the new guidance was accomplished through a combination of retrospective (cash flows), cumulative-effect adjustment to equity (forfeitures) and prospective methodologies (tax windfalls and shortfalls). FHN estimates, based on currently enacted tax rates, that adoption of ASU 2016-09 in 2017 will result in an incremental effect on tax provision ranging from $2.0 million of tax benefit to $1.0 million of additional tax provision. The actual effects of adoption in 2017 will primarily depend upon the share price of the FHN’s common stock, which affects the vesting of certain performance awards, probability of exercise of certain stock options and the magnitude of windfalls for all awards upon either vesting or exercise. The effects on earnings per share calculations and election to account for forfeitures as incurred have not been significant. Effective January 1, 2017, FHN early adopted the provisions of ASU 2016-16, “Intra-Entity Transfers of Assets Other Than Inventory” which requires recognition of the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. Therefore, ASU 2016-16 reverses the previous requirement to delay recognition of the tax consequences of these transactions until the associated assets are sold to an outside party. Adoption of ASU 2016-16 did not have a significant effect on FHN. Accounting Changes Issued but Not Currently Effective In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers.” ASU 2014-09 does not change revenue recognition for financial assets. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This is accomplished through a five-step recognition framework involving 1) the identification of contracts with customers, 2) identification of performance obligations, 3) determination of the transaction price, 4) allocation of the transaction price to the performance obligations and 5) recognition of revenue as performance obligations are satisfied. Additionally, qualitative and quantitative information is required for disclosure regarding the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. In February 2016, the FASB issued ASU 2016-08, “Principal versus Agent Considerations,” which provides additional guidance on whether an entity should recognize revenue on a gross or net basis, based on which party controls the specified good or service before that good or service is transferred to a customer. In April 2016, the FASB issued ASU 2016-10, “Identifying Performance Obligations and Licensing,” which clarifies the original guidance included in ASU 2014-09 for identification of the goods or services provided to customers and enhances the implementation guidance for licensing arrangements. ASU 2016-12, “Narrow-Scope Improvements and Practical Expedients,” was issued in May 2016 to provide additional guidance for the implementation and application of ASU 2014-09. “Technical Corrections and Improvements” ASU 2016-20 was issued in December 2016 and provides further guidance on certain issues. These ASUs are effective in annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early application is permitted for annual reporting periods beginning after December 15, 2016, and associated interim periods. Transition to the new requirements may be made by retroactively revising prior financial statements (with certain practical expedients permitted) or by a cumulative effect through retained earnings. If the latter option is selected, additional disclosures are required for comparability. FHN will not early adopt these ASUs and is evaluating their effects on its revenue recognition practices. Currently, FHN anticipates that it will elect to adopt the provisions of the revenue recognition standards through a cumulative effect to retained earnings with comparability disclosures provided throughout 2018. In February 2017, the FASB issued ASU 2017-05, “Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets” which clarifies the meaning and application of the term in substance nonfinancial asset in transactions involving both financial and nonfinancial assets. If substantially all of the fair value of the assets that are promised to the counterparty in a contract are concentrated in nonfinancial assets, then all of the financial assets promised to the counterparty are in substance nonfinancial assets within the scope of revenue recognition guidance for nonfinancial assets. ASU 2017-05 also clarifies that an entity should identify each distinct nonfinancial asset or in substance nonfinancial asset promised to a counterparty and derecognize each asset when a counterparty obtains control of it with the amount of revenue recognized based on the allocation guidance provided in ASU 2014-09. ASU 2017-05 also requires an entity to derecognize a distinct nonfinancial asset or distinct in substance nonfinancial asset in a partial sale transaction when it 1) does not have (or ceases to have) a controlling financial interest in the legal entity that holds the asset in accordance with Topic 810 and 2) transfers control of the asset in accordance with the provisions of ASU 2014-09. Once an entity transfers control of a distinct nonfinancial asset or distinct in substance nonfinancial asset, it is required to measure any noncontrolling interest it receives (or retains) at fair value. ASU 2017-05 has the same effective date and transition provisions as ASU 2014-09 and the two standards must be adopted simultaneously although the transition methods may be different. FHN is evaluating the effects of ASU 2017-05 on its revenue recognition practices. Currently, FHN anticipates that it will elect to adopt the provisions of ASU 2017-05 through a cumulative effect to retained earnings with comparability disclosures provided throughout 2018. In January 2016, the FASB issued ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities.” ASU 2016-01 makes several revisions to the accounting, presentation and disclosure for financial instruments. Equity investments (except those accounted for under the equity method, those that result in consolidation of the investee, and those held by entities subject to specialized industry accounting which already apply fair value through earnings) are required to be measured at fair value with changes in fair value recognized in net income. This excludes FRB and FHLB stock holdings which are specifically exempted from the provisions of ASU 2016-01. An entity may elect to measure equity investments that do not have readily determinable market values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or similar instruments from the same issuer. ASU 2016-01 also requires a qualitative impairment review for equity investments without readily determinable fair values, with measurement at fair value required if impairment is determined to exist. For liabilities for which fair value has been elected, ASU 2016-01 revises current accounting to record the portion of fair value changes resulting from instrument-specific credit risk within other comprehensive income rather than earnings. FHN has not elected fair value accounting for any existing financial liabilities. Additionally, ASU 2016-01 clarifies that the need for a valuation allowance on a deferred tax asset related to available-for-sale securities should be assessed in combination with all other deferred tax assets rather than being assessed in isolation. ASU 2016-01 also makes several changes to existing fair value presentation and disclosure requirements, including a provision that all disclosures must use an exit price concept in the determination of fair value. ASU 2016-01 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Transition will be through a cumulative effect adjustment to retained earnings for equity investments with readily determinable fair values. Equity investments without readily determinable fair values, for which the accounting election is made, will have any initial fair value marks recorded through earnings prospectively after adoption. Upon adoption, FHN will reclassify all equity investments out of available-for-sale securities, leaving only debt securities within this classification. FHN has evaluated the nature of its current equity investments and determined that substantially all qualify for the election available to assets without readily determinable fair values, including its holdings of Visa Class B shares. Accordingly, FHN intends to apply this election and any fair value marks for these investments will be recognized through earnings on a prospective basis subsequent to adoption. FHN continues to evaluate the appropriate characteristics of “similar” instruments as well as related valuation inputs and methodologies for its equity investments without readily determinable fair values. The requirements of ASU 2016-01 related to assessment of deferred tax assets and disclosure of the fair value of financial instruments will not have a significant effect on FHN because its current accounting and disclosure practices conform to the requirements of ASU 2016-01. FHN also continues to evaluate the impact of ASU 2016-01 on other aspects of its current accounting and disclosure practices. In February 2016, the FASB issued ASU 2016-02, “Leases,” which requires a lessee to recognize in its statement of condition a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. ASU 2016-02 leaves lessor accounting largely unchanged from prior standards. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it should recognize lease expense for such leases generally on a straight-line basis over the lease term. All other leases must be classified as financing or operating leases which depends on the relationship of the lessee’s rights to the economic value of the leased asset. For finance leases, interest on the lease liability is recognized separately from amortization of the right-of-use asset in earnings, resulting in higher expense in the earlier portion of the lease term. For operating leases, a single lease cost is calculated so that the cost of the lease is allocated over the lease term on a generally straight-line basis. In transition to ASU 2016-02, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply, which would result in continuing to account for leases that commence before the effective date in accordance with previous requirements (unless the lease is modified) except that lessees are required to recognize a right-of-use asset and a lease liability for all operating leases at each reporting date based on the present value of the remaining minimum rental payments that were tracked and disclosed under previous requirements. ASU 2016-02 also requires expanded qualitative and quantitative disclosures to assess the amount, timing, and uncertainty of cash flows arising from lease arrangements. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. FHN is evaluating the impact of ASU 2016-02 on its current accounting and disclosure practices. In March 2016, the FASB issued ASU 2016-04, “Recognition of Breakage of Certain Prepaid Stored-Value Products,” which indicates that liabilities related to the sale of prepaid stored-value products are considered financial liabilities and should have a breakage estimate applied for estimated unused funds. ASU 2016-04 does not apply to stored-value products that can only be redeemed for cash, are subject to escheatment or are linked to a segregated bank account. ASU 2016-04 is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. FHN is evaluating the impact of ASU 2016-04 on its current accounting and disclosure practices. In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments,” which revises the measurement and recognition of credit losses for assets measured at amortized cost (e.g., held-to-maturity (“HTM”) loans and debt securities) and available-for-sale (“AFS”) debt securities. Under ASU 2016-13, for assets measured at amortized cost, the current expected credit loss (“CECL”) is measured as the difference between amortized cost and the net amount expected to be collected. This represents a departure from existing GAAP as the “incurred loss” methodology for recognizing credit losses delays recognition until it is probable a loss has been incurred. The measurement of current expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. Additionally, current disclosures of credit quality indicators in relation to the amortized cost of financing receivables will be further disaggregated by year of origination. ASU 2016-13 leaves the methodology for measuring credit losses on AFS debt securities largely unchanged, with the maximum credit loss representing the difference between amortized cost and fair value. However, such credit losses will be recognized through an allowance for credit losses, which permits recovery of previously recognized credit losses if circumstances change. ASU 2016-13 also revises the recognition of credit losses for purchased financial assets with a more-than insignificant amount of credit deterioration since origination (“PCD assets”). For PCD assets, the initial allowance for credit losses is added to the purchase price. Only subsequent changes in the allowance for credit losses are recorded as a credit loss expense for PCD assets. Interest income for PCD assets will be recognized based on the effective interest rate, excluding the discount embedded in the purchase price that is attributable to the acquirer’s assessment of credit losses at acquisition. Currently, credit losses for purchased credit-impaired assets are included in the initial basis of the assets with subsequent declines in credit resulting in expense while subsequent improvements in credit are reflected as an increase in the future yield from the assets. The provisions of ASU 2016-13 will be generally adopted through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in the year of adoption. Prospective implementation is required for debt securities for which an other-than-temporary-impairment (“OTTI”) had been previously recognized. Amounts previously recognized in accumulated other comprehensive income (“AOCI”) as of the date of adoption that relate to improvements in cash flows expected to be collected will continue to be accreted into income over the remaining life of the asset. Recoveries of amounts previously written off relating to improvements in cash flows after the date of adoption will be recorded in earnings when received. A prospective transition approach will be used for existing PCD assets where, upon adoption, the amortized cost basis will be adjusted to reflect the addition of the allowance for credit losses. Thus, an entity will not be required to reassess its purchased financial assets that exist as of the date of adoption to determine whether they would have met at acquisition the new criteria of more-than-insignificant credit deterioration since origination. An entity will accrete the remaining noncredit discount (based on the revised amortized cost basis) into interest income at the effective interest rate at the adoption date. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted in fiscal years beginning after December 15, 2018. FHN is still evaluating the impact of ASU 2016-13 on its current accounting and disclosure practices. In August 2016, the FASB issued ASU 2016-15, “Classification of Certain Cash Receipts and Cash Payments,” which clarifies multiple cash flow presentation issues including providing guidance as to classification on the cash flow statement for certain cash receipts and cash payments where diversity in practice exists. ASU 2016-15 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The provisions of ASU 2016-15 will be applied retroactively and will result in proceeds from bank-owned life insurance (“BOLI”) being classified as an investing activity rather than their prior classification as an operating activity. In March 2017, the FASB issued ASU 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost” which requires the disaggregation of the service cost component from the other components of net benefit cost for pension and postretirement plans. Service cost must be included in the same income statement line item as other compensation-related expenses. All other components of net benefit cost are required to be presented in the income statement separately from the service cost component, with disclosure of the line items where these amounts are recorded. The presentation requirements of ASU 2017-07 must be applied retrospectively and adoption is required for annual periods beginning after December 15, 2017, including interim periods within those annual periods. FHN’s disclosures for pension and postretirement costs provide details of the service cost and all other components for expenses recognized for its applicable benefit plans. These amounts are currently included in Employee compensation, incentives, and benefits expense in the Consolidated Condensed Statements of Income. Upon adoption of ASU 2017-07 FHN will reclassify the expense components other than service cost into All other expense and revise its disclosures accordingly. The amounts to be reclassified are presented in Note 11—Pension, Savings, and Other Employee Benefits in this Quarterly Report on Form 10-Q for the quarter ended June 30, 2017 and in Note 18—Pension, Savings, and Other Employee Benefits in Exhibit 13 to FHN’s Annual Report on Form 10-K for the year ended December 31, 2016 . In March 2017, the FASB issued ASU 2017-08, “Premium Amortization on Purchased Callable Debt Securities” which shortens the amortization period for securities that have explicit, noncontingent call features that are callable at fixed prices and on preset dates. In contrast to the current requirement for premium amortization to extend to the contractual maturity date, ASU 2017-08 requires the premium to be amortized to the earliest call date. ASU 2017-08 does not change the amortization of discounts, which will continue to be amortized to maturity. The new guidance does not apply to debt securities where the prepayment date is not preset or the price is not known in advance, which includes debt securities that qualify for amortization based on estimated prepayment rates. ASU 2017-08 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018 with early adoption permitted. Transition is accomplished through a cumulative-effect adjustment directly to retained earnings as of the beginning of the year of adoption. Based upon the current composition of its debt securities portfolios, FHN does not anticipate a significant effect upon adoption.

Acquisitions and Divestitures	Jun. 30, 2017
Business Combinations [Abstract]
Acquisitions and Divestitures	Acquisitions and Divestitures On May 4, 2017, FHN and Capital Bank Financial Corp. (“Capital Bank” or "CBF") announced that they had entered into an agreement and plan of merger. Under the agreement FHN will acquire Capital Bank, which is headquartered in Charlotte, North Carolina, and reported approximately $10 billion of assets at March 31, 2017. At the time of announcement Capital Bank operated 193 branches in North and South Carolina, Tennessee, Florida and Virginia. Collectively, Capital Bank shareholders will receive approximately $411 million in cash plus FHN common shares which are expected to represent approximately 29 percent of FHN’s outstanding common shares immediately after consummation of the merger. The total transaction value, measured at the time of announcement, was approximately $2.2 billion . The agreement calls for two members of Capital Bank’s board of directors to join FHN’s board after closing. The transaction is expected to close in fourth quarter 2017, subject to regulatory approvals, approval by shareholders of FHN and of Capital Bank, and other customary conditions. On April 3, 2017, FTN Financial acquired substantially all of the assets and assumed substantially all of the liabilities of Coastal Securities, Inc. (“Coastal”), a national leader in the trading, securiti zation, and analysis of Small Business Administration (“SBA”) loans, for appro ximately $131 million in cash. Coastal, which was based in Houston, TX, also traded United States Department of Agriculture (“USDA”) loans and fixed income products and provided municipal underwriting and advisory services to its clients. Coastal’s government-guaranteed loan products, combined with FTN Financial’s existing SBA trading activities, have established an additional major product sector for FTN Financial. The following schedule details acquired assets and liabilities and consideration paid, as well as preliminary adjustments to record the assets and liabilities at their estimated fair values as of April 3, 2017: Coastal Securities, Inc. Purchase Accounting/ As Fair Value As recorded (Dollars in thousands) Acquired Adjustments by FHN Assets: Cash and due from banks $ 7,502 $ — $ 7,502 Interest-bearing cash 4,132 — 4,132 Trading securities 423,662 (284,580 ) 139,082 Loans held-for-sale — 236,088 236,088 Investment securities — 1,413 1,413 Other intangible assets, net — 27,300 27,300 Premises and equipment, net 1,229 — 1,229 Other assets 1,658 14 1,672 Total assets acquired $ 438,183 $ (19,765 ) $ 418,418 Liabilities: Securities sold under agreements to repurchase $ 201,595 $ — $ 201,595 Other short-term borrowings 33,509 — 33,509 Fixed income payables 143,647 (47,158 ) 96,489 Other liabilities 958 (642 ) 316 Total liabilities assumed 379,709 (47,800 ) 331,909 Net Assets Acquired $ 58,474 $ 28,035 86,509 Consideration paid: Cash (131,473 ) Goodwill $ 44,964 The valuation of other intangible assets, including customer relationships and noncompete agreements, are preliminary as management continues to review the valuation assumptions and methodologies for these assets. In relation to the acquisition, FHN has recorded $45.0 million in goodwill, representing the excess of acquisition consideration over the estimated fair value of net assets acquired (refer to Note 6 - Intangible Assets for additional information), and all of which is expected to be deductible for tax purposes. The goodwill is the result of adding an experienced workforce, establishing an additional major product sector for FTN Financial, expected synergies, and other factors. FHN's operating results for 2017 include the operating results of the acquired assets and assumed liabilities of Coastal subsequent to the acquisition on April 3, 2017. In second quarter 2016, FHN recognized $6.4 million of acquisition-related expenses primarily associated with the CBF and Coastal acquisitions. These expenses were primarily included in Professional fees, Legal fees, and Employee compensation, incentives and benefits on the Consolidated Condensed Statements of Income. On September 16, 2016, FTBNA acquired $537.4 million in unpaid principal balance (“UPB”) of restaurant franchise loans from GE Capital’s Southeast and Southwest regional portfolios. Subsequent to the acquisition the acquired loans were combined with existing FTBNA relationships to establish a franchise finance specialty banking business. In addition to the transactions mentioned above, FHN acquires or divests assets from time to time in transactions that are considered business combination or divestitures but are not material to FHN individually or in the aggregate.

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 changes in interest rates and not credit losses. For equity securities, FHN has both the ability and intent to hold these securities for the time necessary to recover the amortized cost.

See Note 13—Variable Interest Entities for additional information. COMPONENTS OF THE LOAN PORTFOLIO The loan portfolio is disaggregated into segments and then further disaggregated into classes for certain disclosures. GAAP defines a portfolio segment as the level at which an entity develops and documents a systematic method for determining its allowance for credit losses. A class is generally determined based on the initial measurement attribute (i.e., amortized cost or purchased credit-impaired), risk characteristics of the loan, and FHN’s method for monitoring and assessing credit risk. Commercial loan portfolio segments include commercial, financial and industrial (“C&I”) and commercial real estate (“CRE”). Commercial classes within C&I include general C&I, loans to mortgage companies, the trust preferred loans (“TRUPS”) (i.e. long-term unsecured loans to bank and insurance—related businesses) portfolio and purchased credit-impaired (“PCI”) loans. Loans to mortgage companies include commercial lines of credit to qualified mortgage companies primarily for the temporary warehousing of eligible mortgage loans prior to the borrower’s sale of those mortgage loans to third party investors. Commercial classes within CRE include income CRE, residential CRE and PCI loans. Consumer loan portfolio segments include consumer real estate, permanent mortgage, and the credit card and other portfolio. Consumer classes include home equity lines of credit (“HELOCs”), real estate (“R/E”) installment and PCI loans within the consumer real estate segment, permanent mortgage (which is both a segment and a class), and credit card and other. Concentrations FHN has a concentration of residential real estate loans ( 24 percent of total loans), the majority of which is in the consumer real estate segment ( 22 percent of total loans). Loans to finance and insurance companies total $2.7 billion ( 22 percent of the C&I portfolio, or 14 percent of the total loans). FHN had loans to mortgage companies totaling $2.1 billion ( 17 percent of the C&I segment, or 10 percent of total loans) as of June 30, 2017 . As a result, 39 percent of the C&I segment is sensitive to impacts on the financial services industry. Purchased Credit-Impaired Loans The following table presents a rollforward of the accretable yield for the three and six months ended June 30, 2017 and 2016 : Three Months Ended Six Months Ended (Dollars in thousands) 2017 2016 2017 2016 Balance, beginning of period $ 5,198 $ 8,958 $ 6,871 $ 8,542 Accretion (919 ) (996 ) (1,770 ) (2,147 ) Adjustment for payoffs (761 ) (2,452 ) (1,034 ) (4,229 ) Adjustment for charge-offs — (11 ) — (674 ) Adjustment for pool excess recovery (a) — — (222 ) — Increase/(decrease) in accretable yield (b) 409 705 114 4,712 Other 118 (33 ) 86 (33 ) Balance, end of period $ 4,045 $ 6,171 $ 4,045 $ 6,171 (a) Represents the removal of accretable difference for the remaining loans in a pool which is now in a recovery state. (b) Includes changes in the accretable yield due to both transfers from the nonaccretable difference and the impact of changes in the expected timing of the cash flows. At June 30, 2017 , the ALLL related to PCI loans was $.5 million compared to $.7 million at December 31, 2016 . A loan loss provision credit related to PCI loans of $.1 million was recognized during the three months ended June 30, 2017 , as compared to $.4 million recognized during the three months ended June 30, 2016 . The loan loss provision credit related to PCI loans of $.2 million was recognized during the six months ended June 30, 2017 , as compared to $.3 million recognized during the six months ended June 30, 2016 . The following table reflects the outstanding principal balance and carrying amounts of the acquired PCI loans as of June 30, 2017 and December 31, 2016 : June 30, 2017 December 31, 2016 (Dollars in thousands) Carrying value Unpaid balance Carrying value Unpaid balance Commercial, financial and industrial $ 21,143 $ 22,089 $ 40,368 $ 41,608 Commercial real estate 4,008 5,264 4,763 6,514 Consumer real estate 1,013 1,388 1,172 1,677 Credit card and other 55 63 52 64 Total $ 26,219 $ 28,804 $ 46,355 $ 49,863 Impaired Loans The following tables provide information at June 30, 2017 and December 31, 2016 , by class related to individually impaired loans and consumer TDRs, regardless of accrual status.

Asset Quality Indicators FHN employs a dual grade commercial risk grading methodology to assign an estimate for the probability of default (“PD”) and the loss given default (“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 . 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. 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. Loan grading discipline is regularly reviewed internally by Credit Assurance Services 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. 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. See Note 5 – Allowance for Loan Losses for further discussion on the credit grading system.

Based on the underlying structure of the notes, the highest possible internal grade is “ 13 ”. The consumer 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 consumer loan-types, FHN is able to utilize the Fair Isaac Corporation (“FICO”) score, among other attributes, to assess the credit 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 consumer portfolio.

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. 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. Concessions could include extension of the maturity date, reductions of the interest rate (which may make the rate lower than current market for a new loan with similar risk), reduction or forgiveness of accrued interest, or principal forgiveness. The assessments of whether a borrower is experiencing (or is likely to experience) financial difficulty, and whether a concession has been granted, are 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, 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 the former 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-to-income ratio. After 5 years , the interest rate generally returns to the original interest rate prior to modification; for certain modifications, the modified interest rate increases 2 percent per year until the original interest rate prior to modification is achieved. 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-to-income ratio. After 5 years , the interest rate steps up 1 percent every year until it reaches the Federal Home Loan Mortgage Corporation 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. Despite the absence of a loan modification, the discharge of personal liability through bankruptcy proceedings is considered a concession. As a result, FHN classifies all non-reaffirmed residential real estate loans discharged in Chapter 7 bankruptcy as nonaccruing TDRs. On June 30, 2017 and December 31, 2016 , FHN had $252.7 million and $285.2 million of portfolio loans classified as TDRs, respectively. For TDRs in the loan portfolio, FHN had loan loss reserves of $42.1 million , or 17 percent as of June 30, 2017 , and $44.9 million , or 16 percent as of December 31, 2016 . Additionally, $66.1 million and $69.3 million of loans held-for-sale as of June 30, 2017 and December 31, 2016 , respectively, were classified as TDRs. The following tables reflect portfolio loans that were classified as TDRs during the three and six months ended June 30, 2017 and 2016 : Three Months Ended June 30, 2017 Six Months Ended June 30, 2017 (Dollars in thousands) Number Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment Number Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment Commercial (C&I): General C&I 1 $ 815 $ 799 2 $ 842 $ 836 Total commercial (C&I) 1 815 799 2 842 836 Consumer real estate: HELOC 27 2,293 2,270 62 4,882 4,743 R/E installment loans 14 799 782 28 1,756 1,684 Total consumer real estate 41 3,092 3,052 90 6,638 6,427 Permanent mortgage 4 699 693 9 2,009 1,996 Credit card & other 23 144 140 29 165 160 Total troubled debt restructurings 69 $ 4,750 $ 4,684 130 $ 9,654 $ 9,419 Three Months Ended June 30, 2016 Six Months Ended June 30, 2016 (Dollars in thousands) Number Pre-Modification Post-Modification Number Pre-Modification Post-Modification Commercial (C&I): General C&I 4 $ 19,175 $ 18,067 5 $ 19,883 $ 18,775 Total commercial (C&I) 4 19,175 18,067 5 19,883 18,775 Consumer real estate: HELOC 53 5,258 5,246 152 12,698 12,616 R/E installment loans 19 3,326 3,614 34 4,224 4,509 Total consumer real estate 72 8,584 8,860 186 16,922 17,125 Permanent mortgage 4 841 840 4 841 840 Credit card & other 1 2 2 5 21 20 Total troubled debt restructurings 81 $ 28,602 $ 27,769 200 $ 37,667 $ 36,760 The following tables present TDRs which re-defaulted during the three and six months ended June 30, 2017 and 2016 , and as to which the modification occurred 12 months or less prior to the re-default.

Accounts, Notes, Loans and Financing Receivable, Gross, Allowance, and Net [Abstract]
Allowance	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 consumer 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 current economic conditions and trends, performance of the housing market, unemployment levels, labor participation rate, regulatory guidance, and both positive and negative portfolio segment-specific trends, are examples of additional factors considered by management in determining the ALLL. Additionally, management considers the inherent uncertainty of quantitative models that are driven by historical loss data. Management evaluates the periods of historical losses that are the basis for the loss rates used in the quantitative models and selects historical loss periods that are believed to be the most reflective of losses inherent in the loan portfolio as of the balance sheet date. Management also periodically reviews analysis of the loss emergence period which is the amount of time it takes for a loss to be confirmed (initial charge-off) after a loss event has occurred. FHN performs extensive studies as it relates to the historical loss periods used in the model and the loss emergence period and model assumptions are adjusted accordingly. The ALLL also includes reserves determined in accordance with ASC 310-10-35 for loans determined by management to be individually impaired and an allowance associated with PCI loans. See Note 1 – Summary of Significant Accounting Policies and Note 5 - Allowance for Loan Losses in the Notes to Consolidated Financial Statements on FHN’s Form 10-K for the year ended December 31, 2016 , for additional information about the policies and methodologies used in the aforementioned components of the ALLL.

Commitments and Contingencies Disclosure [Abstract]
Contingencies And Other Disclosures	Contingencies and Other Disclosures CONTINGENCIES Contingent Liabilities Overview 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. Pending and threatened litigation matters sometimes are resolved in court or before an arbitrator, and sometimes are settled by the parties. Regardless of the manner of resolution, frequently the most significant changes in status of a matter occur over a short time period, often following a lengthy period of little substantive activity. 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 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 a loss contingency liability for a litigation matter when loss is both probable and reasonably estimable as prescribed by applicable financial accounting guidance. 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. Based on current knowledge, and after consultation with counsel, management is of the opinion that loss contingencies related to 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. Material Loss Contingency Matters Summary As used in this Note, “material loss contingency matters” generally fall into at least one of 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 certain matters reported as having been substantially settled or otherwise substantially resolved; (ii) FHN has determined material loss to be probable but is not reasonably able to estimate an amount or range of material loss liability; or (iii) FHN has determined that material loss is not probable but is reasonably possible, and that the amount or range of that reasonably possible material loss is estimable. As defined in applicable accounting guidance, loss is reasonably possible if there is more than a remote chance of a material loss outcome for FHN. Set forth below are disclosures for certain pending or threatened litigation matters, including all matters mentioned in (i) or (ii) and certain matters mentioned in (iii). In addition, certain other matters, or groups of matters, are discussed relating to FHN’s former mortgage origination and servicing businesses. In all litigation matters discussed, unless settled or otherwise 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 June 30, 2017 , the aggregate amount of liabilities established for all such loss contingency matters was $1.1 million . These liabilities are separate from those discussed under the heading “Repurchase and Foreclosure Liability” below. In each material loss contingency matter, except as otherwise noted, there is more than a remote chance that any 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 June 30, 2017 , FHN estimates that for all material loss contingency matters, estimable reasonably possible losses in future periods in excess of currently established liabilities could aggregate in a range from zero to approximately $52 million . As a result of the general uncertainties discussed above and the specific uncertainties discussed for each matter mentioned below, it is possible that the ultimate future loss experienced by FHN for any particular matter may materially exceed the amount, if any, of currently established liability for that matter. That possibility exists both for matters included in the estimated reasonably possible loss (“RPL”) range mentioned above and for matters not included in that range. Material Matters FHN, along with multiple co-defendants, is defending lawsuits brought by investors which claim that the offering documents under which certificates relating to First Horizon branded securitizations were sold to them were materially deficient. One of those matters is viewed as material currently: Federal Deposit Insurance Corporation (“FDIC”) as 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 plaintiff in that suit claims to have purchased (and later sold) certificates totaling $83.4 million , relating to a number of separate securitizations. Plaintiff demands damages and prejudgment interest, among several remedies sought. The current RPL estimate for this matter is subject to significant uncertainties regarding: the dollar amounts claimed; the potential remedies that might be available or awarded; the outcome of any settlement discussions; the availability of significantly dispositive defenses; and the incomplete status of the discovery process. Additional information concerning FHN’s former mortgage businesses is provided below in “Obligations from Legacy Mortgage Businesses.” Underwriters are co-defendants in the FDIC-New York matter 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 certificates in FH proprietary securitizations but as to which FHN has not been named a defendant. For most pending indemnity claims FHN is unable to estimate an RPL range 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 incomplete status of the discovery process; the lack of a precise statement of damages; and lack of precedent claims. The alleged purchase prices of the certificates subject to pending indemnification claims, excluding the FDIC-New York matter, total $409.9 million . FHN has additional potential exposures related to its former mortgage businesses. A few of those matters have become litigation which FHN currently estimates are immaterial, some are non-litigation claims or threats, some are mere subpoenas or other requests for information, and in some areas FHN has no indication of any active or threatened dispute. Some of those matters might eventually result in loan repurchases or make-whole payments and could be included in the repurchase liability discussed below, and some might eventually result in damages or other litigation-oriented liability, including indemnity payments, but none are included in the material loss contingency liabilities mentioned above or in the RPL range mentioned above. Additional information concerning such exposures is provided below in “Obligations from Legacy Mortgage Businesses.” Matters Related to Capital Bank Financial Transaction On July 14, 2017, a complaint captioned Robert Garfield v. First Horizon National Corporation, et al., No. CH-17-1022, was filed on behalf of a putative class of FHN shareholders against FHN, its directors, and Capital Bank Financial Corp. (“Capital Bank Financial”) in the Court of Chancery of Shelby County, Tennessee (30th Judicial District), in connection with FHN’s agreement to acquire Capital Bank Financial by merger. The complaint alleges, among other things, that the FHN director defendants breached their fiduciary duties by approving the merger, that Capital Bank Financial aided and abetted such breaches, and that FHN, its directors, and Capital Bank Financial failed to disclose material information in connection with the merger. The complaint seeks, among other things, an order enjoining the merger, as well as other equitable relief and/or money damages, interest, costs, fees (including attorneys' fees), and expenses. In addition, Capital Bank Financial and the individual members of the Capital Bank Financial board of directors have been named as defendants in three substantially similar putative derivative and class action lawsuits filed by alleged shareholders of Capital Bank Financial. These actions are captioned: (1) Bushansky v. Capital Bank Financial Corp., et al., No. 3:17-cv-00422 (W.D. North Carolina filed July 17, 2017); (2) Parshall v. Capital Bank Financial Corp., et al., No. 3:17-cv-00428 (W.D. North Carolina filed July 19, 2017); and (3) Catherine McNamara v. Capital Bank Financial Corp., et al., No. 3:17-cv-00439 (W.D. North Carolina filed July 25, 2017). The Parshall complaint also names FHN as a defendant. The three complaints allege that the registration statement on Form S-4 which FHN filed on June 29, 2017 omits and/or misrepresents material information which renders it false and misleading. Specifically, the complaints allege that the registration statement omits material information regarding (i) the financial projections of Capital Bank Financial, FHN, and the pro forma combined company; (ii) material information regarding the engagement of an investment banker; (iii) the holdings of certain investment bankers in Capital Bank Financial and FHN; and (iv) certain provisions of non-disclosure agreements between Capital Bank Financial and prospective bidders, which included FHN. The complaints further allege that an investment banker’s valuation analyses and fairness opinion were misleading. The complaints seek, among other things, an order enjoining the merger, as well as other equitable relief and/or money damages, interest, costs, fees (including attorneys’ fees) and expenses. The outcome of these pending matters, and any additional future litigation concerning FHN’s transaction with Capital Bank Financial, is uncertain. Any of these suits, if fully or partially successful, could prevent or delay completion of the transaction and could result in substantial costs to FHN, including any costs associated with the indemnification of FHN’s directors and officers and, after the transaction closes, indemnification of Capital Bank Financial's directors and officers. Material Gain Contingency Matter In second quarter 2015 FHN reached an agreement with DOJ and HUD to settle potential claims related to FHN’s underwriting and origination of loans insured by FHA. Under that agreement FHN paid $212.5 million . FHN believes that certain insurance policies, having an aggregate policy limit of $75 million , provide coverage for FHN’s losses and related costs. The insurers have denied and/or reserved rights to deny coverage. FHN sued the insurers to enforce the policies under Tennessee law. The trial court granted summary judgment to the defendants, and FHN has appealed. In connection with this litigation FHN seeks to partly recoup previously recognized expenses associated with the settled matter. Under applicable financial accounting guidance FHN has determined that although material gain from this litigation is not probable, there is a reasonably possible (more than remote) chance of a material gain outcome for FHN. FHN cannot determine a probable outcome that may result from this matter because of the uncertainty of the potential outcomes of the 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 ultimate effect of counterclaims asserted by the defendants. Additional information concerning FHN’s former mortgage businesses is provided below in “Obligations from Legacy Mortgage Businesses.” Obligations from Legacy Mortgage Businesses Loss contingencies mentioned above under “Material Matters” stem from FHN’s former mortgage origination and servicing businesses. FHN retains potential for further exposure, in addition to the matters mentioned, from those former businesses. The following discussion provides context and other information to enhance an understanding of those matters and exposures. Overview Prior to September 2008 FHN originated loans through its legacy mortgage business, primarily first lien home loans, with the intention of selling them. 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: Fannie Mae and Freddie Mac. Also, federally insured or guaranteed whole loans were pooled, and payments to investors were guaranteed through Ginnie Mae. Many mortgage loan originations, especially nonconforming mortgage loans, were sold to investors, or certificate-holders, predominantly through FH proprietary securitizations but also, to a lesser extent, through other whole loans sold to private non-Agency purchasers. FHN used only one trustee for all of its FH proprietary securitizations. FHN also originated mortgage loans eligible for FHA insurance or VA guaranty. In addition, FHN originated and sold HELOCs and second lien mortgages through other whole loans sold to private purchasers and, to a lesser extent, through FH proprietary securitizations. Currently, only one FH securitization of HELOCs remains outstanding. For non-recourse loan sales, FHN has exposure for repurchase of loans, make-whole damages, or other related damages, arising from claims that FHN breached its representations and warranties made at closing to the purchasers, including GSEs, other whole loan purchasers, and the trustee of FH proprietary securitizations. During the time these legacy activities were conducted, FHN frequently sold mortgage loans “with servicing retained.” As a result, FHN accumulated substantial amounts of MSR on its consolidated balance sheet, as well as contractual servicing obligations and related deposits and receivables. FHN conducted a significant servicing business under its First Horizon Home Loans brand. 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 first lien loans sold or securitized having an LTV ratio at origination of greater than 80 percent . In 2007, market conditions deteriorated to the point where mortgage-backed securitizations no longer could be sold economically; FHN’s last securitization occurred that year. FHN continued selling mortgage loans to GSEs until August 31, 2008, when FHN sold its national mortgage origination and servicing platforms along with a portion of its servicing assets and obligations. FHN contracted to have its remaining servicing obligations sub-serviced. Since the platform sale FHN has sold substantially all remaining servicing assets and obligations. Certain mortgage-related terms used in this “Contingencies” section are defined in “Mortgage-Related Glossary” at the end of this Overview. Repurchase and Make-Whole Obligations Starting in 2009, FHN received a high number of claims either to repurchase loans from the purchaser or to pay the purchaser to “make them whole” for economic losses incurred. These claims have been driven primarily by loan delinquencies. In repurchase or make-whole claims a loan purchaser typically asserts that specified loans violated representations and warranties FHN made when the loans were sold. A significant majority of claims received overall have come from GSEs, and the remainder are from purchasers of other whole loan sales. FHN has not received a loan repurchase or make-whole claim from the FH proprietary securitization trustee. Generally, FHN reviews each claim and MI cancellation notice individually. FHN’s responses include appeal, provide additional information, deny the claim (rescission), repurchase the loan or remit a make-whole payment, or reflect cancellation of MI. After several years resolving repurchase and make-whole claims with each GSE on a loan-by-loan basis, in 2013 and 2014 FHN entered into DRAs with the GSEs, resolving at once a large fraction of potential claims. Starting in 2014, the overall number of such claims diminished substantially, primarily as a result of the DRAs. Each DRA resolved obligations associated with loans originated from 2000 to 2008, but certain obligations and loans were excluded. 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 loan repurchase or monetary compensation obligations under the DRAs related to private mortgage insurance rescissions, cancellations, and denials (with certain exceptions). FHN also has exposure related to loans where there has been a prior bulk sale of servicing, as well as certain other whole-loan sales. With respect to loans where there has been a prior bulk sale of servicing, FHN is not responsible for MI cancellations and denials to the extent attributable to the acts of the current servicer. While large portions of repurchase claims from the GSEs were settled with the DRAs, comprehensive settlement of repurchase, make-whole, and indemnity claims with non-Agency claimants is not practical. Such claims that are not resolved by the parties can, and sometimes have, become litigation. FH Proprietary Securitization Actions FHN has potential financial exposure from FH proprietary securitizations outside of the repurchase/make-whole process. Several investors in certificates sued FHN and others starting in 2009, and several underwriters or other counterparties have demanded that FHN indemnify and defend them in securitization lawsuits. The pending suits generally assert that disclosures made to investors in the offering and sale of certificates were legally deficient. Servicing Obligations FHN’s national servicing business was sold as part of the platform sale in 2008. A significant amount of MSR was sold at that time, and a significant amount was retained. The related servicing activities, including foreclosure and loss mitigation practices, not sold in 2008 were 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 fourth 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 was transferred to the buyer in stages, and was substantially completed in first quarter 2014. The servicing still retained by FHN continues to be subserviced. As servicer, FHN had contractual obligations to the owners of the loans (primarily GSEs) and securitization trustees, to handle billing, custodial, and other tasks related to each loan. Each subservicer undertook to perform those obligations on FHN’s behalf during the applicable subservicing period, although FHN legally remained the servicer of record for those loans that were subserviced. The 2008 subservicer has been subject to a consent decree, and entered into a settlement agreement with regulators related to alleged deficiencies in servicing and foreclosure practices. The 2008 subservicer has made demands of FHN, under the 2008 subservicing agreement, to pay certain resulting costs and damages totaling $43.5 million . FHN disagrees with those demands and has made no payments. This disagreement has the potential to result in litigation and, in any such future litigation, the claim against FHN may be substantial. A certificate holder has contacted FHN, claiming that it has been damaged from alleged deficiencies in servicing loans held in certain FH proprietary securitization trusts. The holder has sued the FH securitization trustee on related grounds, but has not yet sued FHN. FHN cannot predict how this matter will proceed nor can FHN predict whether this matter ultimately will be material to FHN. Origination Data From 2005 through 2008, FHN originated and sold $69.5 billion of mortgage loans to the Agencies. This includes $57.6 billion of loans sold to GSEs and $11.9 billion of loans guaranteed by Ginnie Mae. Although FHN conducted these businesses before 2005, GSE loans originated in 2005 through 2008 account for a substantial majority of all repurchase requests/make-whole claims received since the 2008 platform sale. From 2005 through 2007, $26.7 billion of mortgage loans were included in FH proprietary securitizations. The last FH securitization occurred in 2007.

FHN compares the estimated probable incurred losses determined under the applicable loss estimation approaches for the respective periods with current reserve levels. Changes in the estimated required liability levels are recorded as necessary through the repurchase and foreclosure provision. Based on currently available information and experience to date, FHN has evaluated its loan repurchase, make-whole, and certain related exposures and has accrued for losses of $35.3 million and $66.0 million as of June 30, 2017 and December 31, 2016 , 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 Condensed Statements of Condition. Charges/expense reversals to increase/decrease the liability are included within Repurchase and foreclosure provision/(provision credit) on the Consolidated Condensed Statements of Income. The decline in the repurchase and foreclosure liability since year-end is the result of the settlement of certain repurchase claims. 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. Other FHN Mortgage Exposures FHN’s FHA and VA program lending was substantial prior to the 2008 platform sale, and has continued at a much lower level since then. As lender, FHN made certain representations and warranties as to the compliance of the loans with program requirements. Over the past several years, most recently in first quarter 2015, FHN occasionally has recognized significant losses associated with settling claims and potential claims by government agencies, and by private parties asserting claims on behalf of agencies, related to these origination activities. At June 30, 2017 , FHN had not accrued a liability for any matter related to these government lending programs, and no pending or known threatened matter related to these programs represented a material loss contingency described above. At June 30, 2017 , FHN had not accrued a liability for exposure for repurchase of first-lien loans related to FH proprietary securitizations arising from claims from the trustee that FHN breached its representations and warranties in FH proprietary securitizations at closing. FHN’s trustee is a defendant in lawsuits in which the plaintiffs have asserted that the trustee has duties to review loans and otherwise to act against FHN outside of the duties specified in the applicable trust documents; FHN is not a defendant and is not able to assess what, if any, exposure FHN may have as a result of them. FHN is defending, directly or as indemnitor, certain pending lawsuits brought by purchasers of certificates in FH proprietary securitizations or their assignees. FHN believes a new lawsuit based on federal securities claims that offering disclosures were deficient cannot be brought at this time due to the running of applicable limitation periods, but other investor claims, based on other legal theories, might still be possible. Due to sales of MSR starting in 2008, FHN has limited visibility into current loan information such as principal payoffs, refinance activity, delinquency trends, and loan modification activity. Many non-GSE purchasers of whole loans from FHN included those loans in their own securitizations. Regarding such other whole loans sold, FHN made representations and warranties concerning the loans and provided indemnity covenants to the purchaser/securitizer. Typically the purchaser/securitizer assigned key contractual rights against FHN to the securitization trustee. As mentioned above, repurchase, make-whole, indemnity, and other monetary claims related to specific loans are included in the active pipeline and repurchase reserve. In addition, currently the following categories of actions are pending which involve FHN and other whole loans sold: (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, indemnity, and other demands from purchasers or their assignees; and (iv) FHN is a defendant in legal actions involving FHN-originated other whole loans sold, including one of the material matters mentioned above. At June 30, 2017 , FHN’s repurchase and foreclosure liability considered certain known exposures from other whole loans sold. Certain government entities have subpoenaed information from FHN and others. These entities include the FDIC (on behalf of certain failed banks) and the FHLBs of San Francisco, Atlanta, and Seattle, among others. These entities purport to act on behalf of several purchasers of FH proprietary securitizations, and of non-FH securitizations which included other whole loans sold. Collectively, the subpoenas seek information concerning: a number of FH proprietary securitizations and/or underlying loan originations; and originations of certain other whole loans sold which, in many cases, were included by the purchaser in its own securitizations. Some subpoenas fail to identify the specific investments made or loans at issue. Moreover, FHN has limited information regarding at least some of the loans under review. Unless and until a review (if related to specific loans) becomes an identifiable repurchase claim, the associated loans are not considered part of the active pipeline. 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 is prohibited 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. As of June 30, 2017 and December 31, 2016 , the derivative liabilities were $5.7 million and $6.2 million , respectively. 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. The Settlement was vacated upon appeal in June 2016 and the Supreme Court declined to hear the case in March 2017. Accordingly, the outcome of this matter remains uncertain. Additionally, other Covered Litigation matters are also pending judicial resolution. So long as any Covered Litigation matter remains pending, FHN’s ability to transfer its Visa holdings is restricted, with limited exceptions. 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 Condensed Statements of Condition at their historical cost of $0 . As of June 30, 2017 , the conversion ratio is 165 percent reflecting a Visa stock split in March 2015, and the contingent liability is $.8 million . Future funding of the escrow would dilute this conversion ratio by an amount that is not determinable at present. Based on the closing price on June 30, 2017 , assuming conversion into Class A shares at the current conversion ratio, FHN’s Visa holdings would have a value of approximately $172 million . Recognition of this value is dependent upon the final resolution of the remainder of Visa’s Covered Litigation matters without further reduction of the conversion ratio. 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.

General Discussion of Pension and Other Postretirement Benefits [Abstract]
Pension, Savings, And Other Employee Benefits	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 . Benefits under the plan are “frozen” so that years of service and compensation changes after 2012 do not affect the benefit owed. Minimum contributions are based upon actuarially determined amounts necessary to fund the total benefit obligation. Decisions to contribute to the plan are based upon pension funding requirements under the Pension Protection Act, the maximum amount deductible under the Internal Revenue Code, the actual performance of plan assets, and trends in the regulatory environment. FHN contributed $165 million to the qualified pension plan in third quarter 2016. The contribution had no effect on FHN’s 2016 Consolidated Statements of Income. FHN did not make any contributions to the qualified pension plan in the first half of 2017. Management does not currently anticipate that FHN will make a contribution to the qualified pension plan for the remainde r of 2017. 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 by tax rules. 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 $5.1 million for 2016 . FHN anticipates making benefit payments under the non-qualified plans of $5.0 million in 2017 . Savings plan. FHN provides all qualifying full-time employees with the opportunity to participate in FHN's tax qualifi ed 401(k) savings plan. The qualified plan allows employees to defer receipt of earned salary, up to tax law limits, on a tax- advantaged basis. Accounts, which are held in trust, may be invested in a wide range of mutual funds and in FHN common stock. Up to tax law limits, FHN provides a 100 percent match for the first 6 percent of salary deferred, with company matching contributions invested according to a participant’s current investment elections. Through a non-qualified savings restoration plan, FHN provides a restorative benefit to certain highly-compensated employees who participate in the savings plan and whose contribution elections are capped by tax limitations. Other employee benefits. FHN provides postretirement life insurance benefits to certain employees and also provides postretirement medical insurance benefits to retirement-eligible employees. The postretirement medical plan is contributory with FHN contributing a fixed amount for certain participants. FHN’s postretirement benefits include certain prescription drug benefits. The components of net periodic benefit cost for the three months ended June 30 are as follows: Pension Benefits Other Benefits (Dollars in thousands) 2017 2016 2017 2016 Components of net periodic benefit cost Service cost $ 10 $ 10 $ 27 $ 27 Interest cost 7,380 7,882 325 317 Expected return on plan assets (8,890 ) (9,772 ) (237 ) (229 ) Amortization of unrecognized: Prior service cost/(credit) 13 50 24 42 Actuarial (gain)/loss 2,380 2,067 (143 ) (232 ) Net periodic benefit cost/(credit) $ 893 $ 237 $ (4 ) $ (75 ) The components of net periodic benefit cost for the six months ended June 30 are as follows: Pension Benefits Other Benefits (Dollars in thousands) 2017 2016 2017 2016 Components of net periodic benefit cost Service cost $ 19 $ 20 $ 54 $ 55 Interest cost 14,759 15,764 651 634 Expected return on plan assets (17,781 ) (19,545 ) (474 ) (458 ) Amortization of unrecognized: Prior service cost/(credit) 26 99 48 85 Actuarial (gain)/loss 4,760 4,135 (285 ) (465 ) Net periodic benefit cost/(credit) $ 1,783 $ 473 $ (6 ) $ (149 )

Business Segment Information	Jun. 30, 2017
Segment Reporting, Measurement Disclosures [Abstract]
Business Segment Information	Business Segment Information FHN has four business segments: regional banking, fixed income, corporate, and non-strategic. The regional banking segment offers financial products and services, including traditional lending and deposit taking, to consumer and commercial customers in Tennessee and other selected markets. Regional banking also 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 fixed income segment consists of fixed income securities sales, trading, and strategies for institutional clients in the U.S. and abroad, as well as loan sales, portfolio advisory services, and derivative sales. The corporate segment consists of 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, derivative valuation adjustments related to prior sales of Visa Class B shares, and acquisition-related costs. 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. 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. Business segment revenue, expense, asset, and equity 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, to an extent they are 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 average assets for each segment for the three and six months ended June 30 : Three Months Ended Six Months Ended (Dollars in thousands) 2017 2016 2017 2016 Consolidated Net interest income $ 200,701 $ 176,264 $ 390,409 $ 348,338 Provision/(provision credit) for loan losses (2,000 ) 4,000 (3,000 ) 7,000 Noninterest income 127,673 145,514 244,612 279,819 Noninterest expense 217,917 226,822 440,122 453,749 Income/(loss) before income taxes 112,457 90,956 197,899 167,408 Provision/(benefit) for income taxes (a) 17,253 30,016 44,307 54,255 Net income/(loss) $ 95,204 $ 60,940 $ 153,592 $ 113,153 Average assets $ 28,876,350 $ 26,828,548 $ 28,841,422 $ 26,723,621 Three Months Ended Six Months Ended (Dollars in thousands) 2017 2016 2017 2016 Regional Banking Net interest income $ 201,997 $ 178,318 $ 395,386 $ 350,627 Provision/(provision credit) for loan losses 260 10,883 3,358 25,651 Noninterest income 64,737 61,275 123,713 120,551 Noninterest expense 152,659 164,524 300,723 309,920 Income/(loss) before income taxes 113,815 64,186 215,018 135,607 Provision/(benefit) for income taxes 41,136 22,333 77,724 47,709 Net income/(loss) $ 72,679 $ 41,853 $ 137,294 $ 87,898 Average assets $ 18,431,757 $ 16,575,643 $ 18,194,854 $ 16,260,417 Fixed Income Net interest income $ 4,979 $ 3,146 $ 6,130 $ 5,813 Noninterest income 55,205 78,083 106,027 145,205 Noninterest expense 54,001 62,802 102,686 121,427 Income/(loss) before income taxes 6,183 18,427 9,471 29,591 Provision/(benefit) for income taxes 1,946 6,785 2,970 10,677 Net income/(loss) $ 4,237 $ 11,642 $ 6,501 $ 18,914 Average assets $ 2,696,430 $ 2,470,724 $ 2,288,336 $ 2,370,201 Corporate Net interest income/(expense) $ (14,995 ) $ (15,847 ) $ (29,095 ) $ (30,208 ) Noninterest income 6,218 4,909 11,694 10,632 Noninterest expense 24,563 15,930 41,443 29,391 Income/(loss) before income taxes (33,340 ) (26,868 ) (58,844 ) (48,967 ) Provision/(benefit) for income taxes (a) (35,711 ) (12,744 ) (48,769 ) (23,959 ) Net income/(loss) $ 2,371 $ (14,124 ) $ (10,075 ) $ (25,008 ) Average assets $ 6,226,743 $ 5,833,303 $ 6,789,751 $ 6,097,764 Non-Strategic Net interest income $ 8,720 $ 10,647 $ 17,988 $ 22,106 Provision/(provision credit) for loan losses (2,260 ) (6,883 ) (6,358 ) (18,651 ) Noninterest income 1,513 1,247 3,178 3,431 Noninterest expense (13,306 ) (16,434 ) (4,730 ) (6,989 ) Income/(loss) before income taxes 25,799 35,211 32,254 51,177 Provision/(benefit) for income taxes 9,882 13,642 12,382 19,828 Net income/(loss) $ 15,917 $ 21,569 $ 19,872 $ 31,349 Average assets $ 1,521,420 $ 1,948,878 $ 1,568,481 $ 1,995,239 Certain previously reported amounts have been reclassified to agree with current presentation. (a) Provision/(benefit) for income taxes for consolidated results and the Corporate segment for the three and six months ended June 30, 2017, relative to the prior year periods, was affected by a decline in the effective tax rate in 2017 primarily related to the reversal of the valuation allowance for the deferred tax asset related to its 2012 federal capital loss carryforward based on capital gain transactions initiated in second quarter 2017.

Variable Interest Entities

Variable Interest Entities [Abstract]
Variable Interest Entities	Variable Interest Entities ASC 810 defines a VIE as a legal entity where (a) the equity investors, as a group, lack sufficient equity at risk for the entity to finance its activities without additional subordinated financial support, (b) 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, or (3) the right to receive the expected residual returns of the entity, or (c) the entity is structured with non-substantive voting rights. 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 a proprietary HELOC securitization trust it established as a source of liquidity for consumer lending operations. Based on its restrictive nature, the trust is considered a VIE 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 trust’s economic performance. The retention of MSR and a residual interest results in FHN potentially absorbing losses or receiving benefits that are significant to the trust. FHN is considered the primary beneficiary, as it is assumed to have the power, as Master Servicer, to most significantly impact the activities of the VIE. Consolidation of the trust results in the recognition of the trust 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 trust securities. Through first quarter 2016 the trust experienced a rapid amortization period and FHN was obligated to provide subordinated funding. During the period, cash payments from borrowers were accumulated to repay outstanding debt securities while FHN continued to make advances to borrowers when they drew on their lines of credit. FHN then transferred the newly generated receivables into the securitization trust. FHN is reimbursed for these advances 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. Amounts funded from monoline insurance policies are considered restricted term borrowings in FHN’s Consolidated Condensed Statements of Condition. Except for recourse due to breaches of representations and warranties made by FHN in connection with the sale of the loans to the trust, the creditors of the trust hold no recourse to the assets of FHN. 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. The following table summarizes VIEs consolidated by FHN as of June 30, 2017 and December 31, 2016 : June 30, 2017 December 31, 2016 On-Balance Sheet Consumer Loan Securitization Rabbi Trusts Used for Deferred Compensation Plans On-Balance Sheet Consumer Loan Securitization Rabbi Trusts Used for Deferred Compensation Plans ( Dollars in thousands ) Carrying Value Carrying Value Carrying Value Carrying Value Assets: Cash and due from banks $ — N/A $ — N/A Loans, net of unearned income 28,765 N/A 35,873 N/A Less: Allowance for loan losses 52 N/A 587 N/A Total net loans 28,713 N/A 35,286 N/A Other assets 72 $ 77,760 283 $ 74,160 Total assets $ 28,785 $ 77,760 $ 35,569 $ 74,160 Liabilities: Term borrowings $ 15,886 N/A $ 23,126 N/A Other liabilities 3 $ 58,088 3 $ 54,746 Total liabilities $ 15,889 $ 58,088 $ 23,129 $ 54,746 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 units that are 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 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 entities’ economic performance and the managing members are exposed to all losses beyond FTHC’s initial capital contributions and funding commitments. FHN accounts for all qualifying LIHTC investments under the proportional amortization method. Under this 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). LIHTC investments that do not qualify for the proportional amortization method are accounted for using the equity method. Expenses associated with these investments were not significant for the three and six months ended June 30, 2017 and 2016 . The following table summarizes the impact to the Provision/(benefit) for income taxes on the Consolidated Condensed Statements of Income for the three and six months ended June 30, 2017 , and 2016 for LIHTC investments accounted for under the proportional amortization method. Three Months Ended Six Months Ended ( Dollars in thousands ) 2017 2016 2017 2016 Provision/(benefit) for income taxes: Amortization of qualifying LIHTC investments $ 2,362 $ 2,330 $ 4,640 $ 4,628 Low income housing tax credits (2,598 ) (2,534 ) (4,998 ) (5,057 ) Other tax benefits related to qualifying LIHTC investments (910 ) (1,069 ) (1,829 ) (2,179 ) Other Tax Credit Investments. First Tennessee New Markets Corporation (“FTNMC”), a wholly-owned subsidiary of FTBNA, makes equity investments through wholly-owned subsidiaries as a non-managing 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. FTHC also makes equity investments as a limited partner or non-managing member in entities that receive Historic Tax Credits pursuant to Section 47 of the Internal Revenue Code. The purpose of these entities is the rehabilitation of historic buildings with the tax credits provided to incent private investment in the historic cores of cities and towns. These entities 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 entities as it has a risk of loss for its capital contributions and funding commitments to each partnership. The managing members are considered the primary beneficiaries as managerial functions give them the power to direct the activities that most significantly impact the entities’ economic performance and the managing members are exposed to all losses beyond FTHC’s initial capital contributions and funding commitments. 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 Condensed Statements of Condition. FTBNA has no contractual requirements to provide financial support to the trust. Proprietary Residential Mortgage Securitizations. FHN holds variable interests (primarily principal-only strips) in proprietary residential mortgage securitization trusts it established prior to 2008 as a source of liquidity for its mortgage banking operations. Prior to fourth quarter 2016 these interests included MSR and interest-only strips. 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 it held MSR, FHN was assumed to have the power as servicer to most significantly impact the activities of such VIEs. However, in situations where FHN did not have the ability to participate in significant portions of a securitization trust’s cash flows, FHN was not considered the primary beneficiary of the trust. Therefore, these trusts were not consolidated by FHN. Holdings 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. Sale Leaseback Transaction . FTB has entered into an agreement with a single asset leasing entity for the sale and leaseback of an office building. In conjunction with this transaction, FTB loaned funds to a related party of the buyer that were used for the purchase price of the building. FTB also entered into a construction loan agreement with the single asset entity for renovation of the building. Since this transaction did not qualify as a sale, it is being accounted for using the deposit method which creates a net asset or liability for all cash flows between FTB and the buyer. The buyer-lessor in this transaction meets the definition of a VIE as it does not have sufficient equity at risk since FTB is providing the funding for the purchase and renovation. A related party of the buyer-lessor has the power to direct the activities that most significantly impact the operations and could potentially receive benefits or absorb losses that are significant to the transactions, making it the primary beneficiary. Therefore, FTB does not consolidate the leasing entity.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives In the normal course of business, FHN utilizes various financial instruments (including derivative contracts and credit-related agreements) through its fixed income and risk management operations, as part of its risk management strategy and as a means to meet customers’ needs. Derivative 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 the amount of 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”) controls, coordinates, and 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 by 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. Commencing in first quarter 2017, a central clearinghouse revised the treatment of daily margin posted or received from collateral to legal settlements of the related derivative contracts. This change resulted in a reduction in derivative assets and liabilities and corresponding reductions in collateral posted and received as these amounts are now presented net by contract in the Consolidated Condensed Statements of Condition. This change has no effect on hedge accounting or gains/losses for the applicable derivative contracts. On June 30, 2017 and December 31, 2016 , respectively, FHN had $40.4 million and $47.8 million of cash receivables and $30.0 million and $32.8 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 upstream 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. Trading Activities FHN’s fixed income segment trades U.S. Treasury, U.S. Agency, government-guaranteed loan, mortgage-backed, corporate and municipal fixed income securities, and other securities for distribution to customers. When these securities settle on a delayed basis, they are considered forward contracts. Fixed income also enters into interest rate contracts, including caps, swaps, and floors, for its customers. In addition, fixed income 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 fixed income noninterest income. Related assets and liabilities are recorded on the Consolidated Condensed 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 $45.6 million and $69.3 million for the three months ended June 30, 2017 and 2016 , respectively, and $88.3 million and $126.9 million for the six months ended June 30, 2017 and 2016, respectively. Trading revenues are inclusive of both derivative and non-derivative financial instruments, and are included in fixed income noninterest income. The following tables summarize FHN’s derivatives associated with fixed income trading activities as of June 30, 2017 and December 31, 2016 : June 30, 2017 (Dollars in thousands) Notional Assets Liabilities Customer Interest Rate Contracts $ 1,903,647 $ 34,224 $ 12,508 Offsetting Upstream Interest Rate Contracts 1,903,647 12,368 31,374 Option Contracts Purchased 25,000 78 — Forwards and Futures Purchased 4,245,499 3,403 10,366 Forwards and Futures Sold 4,562,708 12,646 2,212 December 31, 2016 (Dollars in thousands) Notional Assets Liabilities Customer Interest Rate Contracts $ 1,697,992 $ 39,495 $ 14,996 Offsetting Upstream Interest Rate Contracts 1,697,992 14,996 39,495 Option Contracts Purchased 17,500 63 — Option Contracts Written 5,000 — 8 Forwards and Futures Purchased 2,916,750 6,257 26,659 Forwards and Futures Sold 3,085,396 27,330 6,615 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, primarily swaps, 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 is 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 upstream 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 Condensed Statements of Income. FHN has designated a derivative transaction in a hedging strategy to manage interest rate risk on $400.0 million of senior debt issued by FTBNA which matures in December 2019. This 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 of the senior debt. The balance sheet impact of this swap was $.2 million in Derivative liabilities as of June 30, 2017 and $1.6 million in Derivative assets as of December 31, 2016 . There was an insignificant level of ineffectiveness related to this hedge. FHN has designated a derivative transaction in a hedging strategy to manage interest rate risk on $500.0 million of senior debt which matures in December 2020. This 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 of the senior debt. The balance sheet impact of this swap was $.6 million and $7.3 million in Derivative liabilities as of June 30, 2017 and December 31, 2016 , respectively. There was an insignificant level of ineffectiveness related to this hedge. The following tables summarize FHN’s derivatives associated with interest rate risk management activities as of June 30, 2017 and December 31, 2016 : June 30, 2017 (Dollars in thousands) Notional Assets Liabilities Customer Interest Rate Contracts Hedging Hedging Instruments and Hedged Items: Customer Interest Rate Contracts $ 1,513,114 $ 17,056 $ 12,944 Offsetting Upstream Interest Rate Contracts 1,513,114 11,878 15,630 Debt Hedging Hedging Instruments: Interest Rate Swaps $ 900,000 N/A $ 796 Hedged Items: Term Borrowings N/A N/A $ 900,000 (a) December 31, 2016 (Dollars in thousands) Notional Assets Liabilities Customer Interest Rate Contracts Hedging Hedging Instruments and Hedged Items: Customer Interest Rate Contracts $ 1,357,920 $ 17,566 $ 14,277 Offsetting Upstream Interest Rate Contracts 1,357,920 14,277 18,066 Debt Hedging Hedging Instruments: Interest Rate Swaps $ 900,000 $ 1,628 $ 7,276 Hedged Items: Term Borrowings N/A N/A $ 900,000 (a) (a) Represents par value of term borrowings being hedged.

(b) Represents gains and losses attributable to changes in fair value due to interest rate risk as designated in ASC 815-20 hedging relationships. In first quarter 2016, FHN entered into a pay floating, receive fixed interest rate swap in a hedging strategy to manage its exposure to the variability in cash flows related to the interest payments for the following five years on $250 million principal of debt instruments, which primarily consist of held-to-maturity trust preferred loans that have variable interest payments based on 3-month LIBOR. In first quarter 2017, FHN initiated cash flow hedges of $650 million notional amount that have durations between three and seven years. The debt instruments primarily consist of held-to-maturity commercial loans that have variable interest payments based on 1-month LIBOR. These qualify for hedge accounting as cash flow hedges under ASC 815-20. Changes in the fair value of these derivatives are recorded as a component of AOCI, to the extent that the hedging relationships are effective. Amounts are reclassified from AOCI to earnings as the hedged cash flows affect earnings. FTB measures the ineffectiveness using the Hypothetical Derivative Method. AOCI is adjusted to an amount that reflects the lesser of either the cumulative change in fair value of the swaps or the cumulative change in the fair value of the hypothetical derivative instruments. To the extent that any ineffectiveness exists in the hedge relationships, the amounts are recorded in current period earnings. Interest paid or received for these swaps is recognized as an adjustment to interest income of the assets whose cash flows are being hedged.

FHN hedges held-to-maturity trust preferred loans 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. Interest paid or received for these swaps is 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 Condensed Statements of Income. These hedges expire in third quarter 2017.

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 June 30, 2017 and December 31, 2016 , the derivative liabilities associated with the sales of Visa Class B shares were $5.7 million and $6.2 million , respectively. See the Visa Matters section of Note 10 – 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 June 30, 2017 and December 31, 2016 , these loans were valued at $1.3 million and $3.8 million , respectively. The balance sheet amount and the gains/losses associated with these derivatives were not significant. 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 standard agreement forms 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 counterparty with access to a clearinghouse occurs and margin is posted. Cash margin received (posted) that is considered settlements for the derivative contracts is included in the respective derivative asset (liability) value. Cash margin that is considered collateral received (posted) for interest rate derivatives is recognized as a liability (asset) on FHN’s Consolidated Condensed Statements of Condition. 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 Condensed 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 require the posting of additional collateral; whereas if a counterparty’s credit ratings were to increase, the counterparty could require 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 $31.0 million of assets and $39.3 million of liabilities on June 30, 2017 , and $35.9 million of assets and $49.0 million of liabilities on December 31, 2016 . As of June 30, 2017 and December 31, 2016 , FHN had received collateral of $110.9 million and $137.6 million and posted collateral of $32.0 million and $39.3 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 require 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 $30.9 million of assets and $16.8 million of liabilities on June 30, 2017 , and $35.9 million of assets and $19.6 million of liabilities on December 31, 2016 . As of June 30, 2017 and December 31, 2016 , FHN had received collateral of $110.9 million and $137.5 million and posted collateral of $11.2 million and $12.9 million , respectively, in the normal course of business related to these contracts. FHN’s fixed income segment 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. 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 following tables. The following table provides details of derivative assets and collateral received as presented on the Consolidated Condensed Statements of Condition as of June 30, 2017 and December 31, 2016 : Gross amounts not offset in the Statements of Condition (Dollars in thousands) Gross amounts of recognized assets Gross amounts offset in the Statements of Condition Net amounts of assets presented in the Statements of Condition (a) Derivative liabilities available for offset Collateral Received Net amount Derivative assets: June 30, 2017 (b) $ 75,526 $ — $ 75,526 $ (22,842 ) $ (47,292 ) $ 5,392 December 31, 2016 (b) 87,962 — 87,962 (25,953 ) (52,888 ) 9,121 (a) Included in Derivative assets on the Consolidated Condensed Statements of Condition.

Offsetting [Abstract]
Master Netting Agreements And Similar Arrangements	Master Netting and Similar Agreements—Repurchase, Reverse Repurchase, and Securities Borrowing Transactions For repurchase, reverse repurchase and securities borrowing 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 through FHN’s fixed income business (Securities purchased under agreements to resell and Securities sold under agreements to repurchase), transactions are collateralized by securities and/or government guaranteed loans 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 sold under agreements to repurchase), securities are typically pledged at settlement and not released until maturity. For asset positions, the collateral is not included on FHN’s Consolidated Condensed 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. The following table provides details of Securities purchased under agreements to resell as presented on the Consolidated Condensed Statements of Condition and collateral pledged by counterparties as of June 30, 2017 and December 31, 2016 : Gross amounts not offset in the Statements of Condition (Dollars in thousands) Gross amounts of recognized assets Gross amounts offset in the Statements of Condition Net amounts of assets presented in the Statements of Condition Offsetting securities sold under agreements to repurchase Securities collateral (not recognized on FHN’s Statements of Condition) Net amount Securities purchased under agreements to resell: June 30, 2017 $ 657,991 $ — $ 657,991 $ (804 ) $ (650,369 ) $ 6,818 December 31, 2016 613,682 — 613,682 (1,628 ) (603,813 ) 8,241 The following table provides details of Securities sold under agreements to repurchase as presented on the Consolidated Condensed Statements of Condition and collateral pledged by FHN as of June 30, 2017 and December 31, 2016 : Gross amounts not offset in the Statements of Condition (Dollars in thousands) Gross amounts of recognized liabilities Gross amounts offset in the Statements of Condition Net amounts of liabilities presented in the Statements of Condition Offsetting securities purchased under agreements to resell Securities/ government guaranteed loans collateral Net amount Securities sold under agreements to repurchase: June 30, 2017 $ 743,684 $ — $ 743,684 $ (804 ) $ (742,727 ) $ 153 December 31, 2016 453,053 — 453,053 (1,628 ) (451,414 ) 11 Due to the short duration of Securities sold under agreements to repurchase and the nature of collateral involved, the risks associated with these transactions are considered minimal.

Fair Value Disclosures [Abstract]
Fair Value Of Assets And Liabilities	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.

(d) Included in Other expense. 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 lower of cost or market (“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 June 30, 2017 , and December 31, 2016 , respectively, the following tables provide the level of valuation assumptions used to determine each adjustment and the related carrying value.

In first quarter 2016, FHN’s Regional Banking segment recognized $3.7 million of impairments on long-lived assets associated with efforts to more efficiently utilize its bank branch locations. The affected branch locations represented a mixture of owned and leased sites. The fair values of owned sites were determined using estimated sales prices from appraisals less estimated costs to sell. The fair values of leased sites were determined using a discounted cash flow approach, based on the revised estimated useful lives of the related assets. Both measurement methodologies are considered Level 3 valuations. Level 3 Measurements The following tables provide information regarding the unobservable inputs utilized in determining the fair value of level 3 recurring and non-recurring measurements as of June 30, 2017 and December 31, 2016 : (Dollars in Thousands) Level 3 Class Fair Value at Valuation Techniques Unobservable Input Values Utilized Available-for-sale- securities SBA-interest only strips $ 1,163 Discounted cash flow Constant prepayment rate 9% - 11% Bond equivalent yield 15%- 19% Loans held-for-sale - residential real estate 21,200 Discounted cash flow Prepayment speeds - First mortgage 2% - 12% Prepayment speeds - HELOC 3% - 15% Foreclosure losses 50% - 70% Loss severity trends - First mortgage 5% - 50% of UPB Loss severity trends - HELOC 15% - 100% of UPB Loans held-for-sale- unguaranteed interest in SBA loans 1,577 Discounted cash flow Constant prepayment rate 8% - 12% Bond equivalent yield 9% - 10% Derivative liabilities, other 5,700 Discounted cash flow Visa covered litigation resolution amount $4.4 billion - $5.2 billion Probability of resolution scenarios 10% - 30% Time until resolution 18 - 48 months Loans, net of unearned income (a) 29,260 Appraisals from comparable properties Marketability adjustments for specific properties 0% - 10% of appraisal Other collateral valuations Borrowing base certificates adjustment 20% - 50% of gross value Financial Statements/Auction values adjustment 0% - 25% of reported value Real estate acquired by foreclosure (b) 7,038 Appraisals from comparable properties Adjustment for value changes since appraisal 0% - 10% of appraisal Other assets (c) 28,156 Discounted cash flow Adjustments to current sales yields for specific properties 0% - 15% adjustment to yield Appraisals from comparable properties Marketability adjustments for specific properties 0% - 25% of appraisal (a) Represents carrying value of loans for which adjustments are required to be based on the appraised value of the collateral less estimated costs to sell.

(b) Represents the fair value of foreclosed properties that were measured subsequent to their initial classification as foreclosed assets. Balance excludes foreclosed real estate related to government insured mortgages. (c) Represents tax credit investments accounted for under the equity method. Securities AFS . Increases (decreases) in estimated prepayment rates and bond equivalent yields negatively (positively) affect the value of SBA interest only strips. Management additionally considers whether loans on the related SBA-interest only strips are delinquent, in default or prepaying, and adjusts the fair value down 20 - 100% depending on the length of time in default. Loans held-for-sale. Foreclosure losses and prepayment 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 quarterly. Fair value measurements are reviewed at least quarterly by FHN’s Corporate Accounting Department. Increases (decreases) in estimated prepayment rates and bond equivalent yields negatively (positively) affect the value of unguaranteed interests in SBA loans. Unguaranteed interest in SBA loans held-for-sale are carried at less than the outstanding balance due to credit risk estimates. Credit risk adjustments may be reduced if prepayment is likely or as consistent payment history is realized. Management also considers other factors such as delinquency or default and adjusts the fair value accordingly. Derivative liabilities. In conjunction with the sales of portions 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. FHN uses a discounted cash flow methodology in order to estimate the fair value of FHN’s derivative liabilities associated with its prior sales of Visa Class B shares. The methodology includes 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. Since this estimation process requires 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. 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 (commercial) and Default Servicing functions (primarily consumer). The Credit Risk Management Committee reviews dispositions and additions of foreclosed assets annually. Back testing is performed during the year through comparison to ultimate disposition values. 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 accounted for under the equity method 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 which typically includes consideration of the underlying property’s appraised value. 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 has 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 reduces certain timing differences and better matches changes in the value of such loans with changes in the value of derivatives and forward delivery commitments used as economic hedges for these assets at the time of election. 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. 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. June 30, 2017 (Dollars in thousands) Fair value carrying amount Aggregate unpaid principal Fair value carrying amount less aggregate unpaid principal Residential real estate loans held-for-sale reported at fair value: Total loans $ 22,220 $ 31,580 $ (9,360 ) Nonaccrual loans 6,419 11,736 (5,317 ) Loans 90 days or more past due and still accruing 35 43 (8 ) December 31, 2016 (Dollars in thousands) Fair value carrying amount Aggregate unpaid principal Fair value carrying amount less aggregate unpaid principal Residential real estate loans held-for-sale reported at fair value: Total loans $ 24,269 $ 35,262 $ (10,993 ) Nonaccrual loans 6,775 12,910 (6,135 ) Loans 90 days or more past due and still accruing 211 331 (120 ) 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: Three Months Ended Six Months Ended (Dollars in thousands) 2017 2016 2017 2016 Changes in fair value included in net income: Mortgage banking noninterest income Loans held-for-sale $ 410 $ 429 $ 1,332 $ 771 For the three months ended June 30, 2017 , and 2016 , the amounts for residential real estate loans held-for-sale include gains of $.2 million in pretax earnings that are attributable to changes in instruments-specific credit risk. For the six months ended June 30, 2017, and 2016, the amounts for residential real estate loans held-for-sale included gains of $.3 million 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 estimated default rates and estimated loss severities. 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 Condensed Statements of Income as interest on loans held-for-sale. FHN has elected to account for retained interest-only strips from guaranteed SBA loans recorded in available-for-sale securities at fair value through earnings. Since these securities are subject to the risk that prepayments may result in FHN not recovering all or a portion of its recorded investment, the fair value election results in a more timely recognition of the effects of estimated prepayments through earnings rather than being recognized through other comprehensive income with periodic review for other-than-temporary impairment. Gains or losses are recognized through fixed income revenues and are presented in the recurring measurements table. 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 recorded at fair value in the Consolidated Condensed 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 mortgage securitizations that qualify as financial assets, which include primarily principal-only strips. FHN uses inputs including yield curves, credit spreads, and prepayment speeds to determine the fair value of principal-only strips. 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, and short-term investments in mutual funds. 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. Investments in the stock of the Federal Reserve Bank and Federal Home Loan Banks are recognized at historical cost in the Consolidated Condensed 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. Investments in equity securities are valued using quoted market prices when available. Cost method investments are valued at historical cost less any recorded impairment due to the illiquid nature of these investments. Interest only strips are valued at elected fair value based on an income approach using an internal valuation model. The internal valuation model includes assumptions regarding projections of future cash flows, prepayment rates, default rates and interest only strip terms. These securities bear the risk of loan prepayment or default that may result in the Company not recovering all or a portion of its recorded investment. When appropriate, valuations are adjusted for various factors including default or prepayment status of the underlying SBA loans. Because of the inherent uncertainty of valuation, those estimated values may be higher or lower than the values that would have been used had a ready market for the securities existed, and may change in the near term. Securities held-to-maturity. Securities held-to-maturity reflects debt securities for which management has the positive intent and ability to hold to maturity. To the extent possible, valuations of held-to-maturity securities are performed using observable inputs obtained from market transactions in similar securities. Typical inputs include LIBOR and U.S. treasury curves and credit spreads. Debt securities 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, the treasury curve and credit spreads from similar instruments. Significant unobservable inputs include estimated credit spreads for individual issuers and instruments as well as prepayment speeds, as applicable. Loans held-for-sale. Residential real estate loans held-for-sale are valued using current transaction prices and/or values on similar assets when available, including committed bids for specific loans or loan portfolios. Uncommitted bids may be adjusted based on other available market information. For all other loans 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. Inputs include current mortgage rates for similar products, estimated prepayment rates, foreclosure losses, and various loan performance measures (delinquency, LTV, credit score). 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 estimated cancellation rates for loans expected to become delinquent. The Company utilizes quoted market prices of similar instruments or broker and dealer quotations to value the SBA and USDA guaranteed loans. The Company values SBA-unguaranteed interests in loans held-for-sale based on individual loan characteristics, such as industry type and pay history which generally follows an income approach. Furthermore, these valuations are adjusted for changes in prepayment estimates and are reduced due to restrictions on trading. The

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis Of Accounting	Basis of Accounting. The unaudited interim consolidated condensed financial statements of First Horizon National Corporation (“FHN”), including its subsidiaries, have been prepared in conformity with accounting principles generally accepted in the United States of America and follow general practices within the industries in which it operates. This preparation requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. These estimates and assumptions are based on information available as of the date of the financial statements and could differ from actual results. In the opinion of management, all necessary adjustments have been made for a fair presentation of financial position and results of operations for the periods presented. These adjustments are of a normal recurring nature unless otherwise disclosed in this Quarterly Report on Form 10-Q. The operating results for the interim 2017 period are not necessarily indicative of the results that may be expected going forward. For further information, refer to the audited consolidated financial statements in Exhibit 13 to FHN’s Annual Report on Form 10-K for the year ended December 31, 2016 .
Summary of Accounting Changes and Accounting Changes Issued But Not Currently Effective	Summary of Accounting Changes. Effective January 1, 2017, FHN adopted the provisions of Accounting Standards Update (“ASU”) 2016-09, “Improvements to Employee Share-Based Payment Accounting,” which makes several revisions to equity compensation accounting. Under the new guidance all excess tax benefits and deficiencies that occur when an award vests, is exercised, or expires are recognized in income tax expense as discrete period items. Previously, these transactions were typically recorded directly within equity. Consistent with this change, excess tax benefits and deficiencies are no longer included within estimated proceeds when performing the treasury stock method for calculation of diluted earnings per share. Excess tax benefits are also recognized at the time an award is exercised or vests compared to the previous requirement to delay recognition until the deduction reduces taxes payable. The presentation of excess tax benefits in the statement of cash flows shifted to an operating activity from the prior classification as a financing activity. ASU 2016-09 also provides an accounting policy election to recognize forfeitures of awards as they occur when estimating stock-based compensation expense rather than the previous requirement to estimate forfeitures from inception. Further, ASU 2016-09 permits employers to use a net-settlement feature to withhold taxes on equity compensation awards up to the maximum statutory tax rate without affecting the equity classification of the award. Under previous guidance, withholding of equity awards in excess of the minimum statutory requirement resulted in liability classification for the entire award. The related cash remittance by the employer for employee taxes is treated as a financing activity in the statement of cash flows. Transition to the new guidance was accomplished through a combination of retrospective (cash flows), cumulative-effect adjustment to equity (forfeitures) and prospective methodologies (tax windfalls and shortfalls). FHN estimates, based on currently enacted tax rates, that adoption of ASU 2016-09 in 2017 will result in an incremental effect on tax provision ranging from $2.0 million of tax benefit to $1.0 million of additional tax provision. The actual effects of adoption in 2017 will primarily depend upon the share price of the FHN’s common stock, which affects the vesting of certain performance awards, probability of exercise of certain stock options and the magnitude of windfalls for all awards upon either vesting or exercise. The effects on earnings per share calculations and election to account for forfeitures as incurred have not been significant. Effective January 1, 2017, FHN early adopted the provisions of ASU 2016-16, “Intra-Entity Transfers of Assets Other Than Inventory” which requires recognition of the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. Therefore, ASU 2016-16 reverses the previous requirement to delay recognition of the tax consequences of these transactions until the associated assets are sold to an outside party. Adoption of ASU 2016-16 did not have a significant effect on FHN. Accounting Changes Issued but Not Currently Effective In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers.” ASU 2014-09 does not change revenue recognition for financial assets. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This is accomplished through a five-step recognition framework involving 1) the identification of contracts with customers, 2) identification of performance obligations, 3) determination of the transaction price, 4) allocation of the transaction price to the performance obligations and 5) recognition of revenue as performance obligations are satisfied. Additionally, qualitative and quantitative information is required for disclosure regarding the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. In February 2016, the FASB issued ASU 2016-08, “Principal versus Agent Considerations,” which provides additional guidance on whether an entity should recognize revenue on a gross or net basis, based on which party controls the specified good or service before that good or service is transferred to a customer. In April 2016, the FASB issued ASU 2016-10, “Identifying Performance Obligations and Licensing,” which clarifies the original guidance included in ASU 2014-09 for identification of the goods or services provided to customers and enhances the implementation guidance for licensing arrangements. ASU 2016-12, “Narrow-Scope Improvements and Practical Expedients,” was issued in May 2016 to provide additional guidance for the implementation and application of ASU 2014-09. “Technical Corrections and Improvements” ASU 2016-20 was issued in December 2016 and provides further guidance on certain issues. These ASUs are effective in annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early application is permitted for annual reporting periods beginning after December 15, 2016, and associated interim periods. Transition to the new requirements may be made by retroactively revising prior financial statements (with certain practical expedients permitted) or by a cumulative effect through retained earnings. If the latter option is selected, additional disclosures are required for comparability. FHN will not early adopt these ASUs and is evaluating their effects on its revenue recognition practices. Currently, FHN anticipates that it will elect to adopt the provisions of the revenue recognition standards through a cumulative effect to retained earnings with comparability disclosures provided throughout 2018. In February 2017, the FASB issued ASU 2017-05, “Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets” which clarifies the meaning and application of the term in substance nonfinancial asset in transactions involving both financial and nonfinancial assets. If substantially all of the fair value of the assets that are promised to the counterparty in a contract are concentrated in nonfinancial assets, then all of the financial assets promised to the counterparty are in substance nonfinancial assets within the scope of revenue recognition guidance for nonfinancial assets. ASU 2017-05 also clarifies that an entity should identify each distinct nonfinancial asset or in substance nonfinancial asset promised to a counterparty and derecognize each asset when a counterparty obtains control of it with the amount of revenue recognized based on the allocation guidance provided in ASU 2014-09. ASU 2017-05 also requires an entity to derecognize a distinct nonfinancial asset or distinct in substance nonfinancial asset in a partial sale transaction when it 1) does not have (or ceases to have) a controlling financial interest in the legal entity that holds the asset in accordance with Topic 810 and 2) transfers control of the asset in accordance with the provisions of ASU 2014-09. Once an entity transfers control of a distinct nonfinancial asset or distinct in substance nonfinancial asset, it is required to measure any noncontrolling interest it receives (or retains) at fair value. ASU 2017-05 has the same effective date and transition provisions as ASU 2014-09 and the two standards must be adopted simultaneously although the transition methods may be different. FHN is evaluating the effects of ASU 2017-05 on its revenue recognition practices. Currently, FHN anticipates that it will elect to adopt the provisions of ASU 2017-05 through a cumulative effect to retained earnings with comparability disclosures provided throughout 2018. In January 2016, the FASB issued ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities.” ASU 2016-01 makes several revisions to the accounting, presentation and disclosure for financial instruments. Equity investments (except those accounted for under the equity method, those that result in consolidation of the investee, and those held by entities subject to specialized industry accounting which already apply fair value through earnings) are required to be measured at fair value with changes in fair value recognized in net income. This excludes FRB and FHLB stock holdings which are specifically exempted from the provisions of ASU 2016-01. An entity may elect to measure equity investments that do not have readily determinable market values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or similar instruments from the same issuer. ASU 2016-01 also requires a qualitative impairment review for equity investments without readily determinable fair values, with measurement at fair value required if impairment is determined to exist. For liabilities for which fair value has been elected, ASU 2016-01 revises current accounting to record the portion of fair value changes resulting from instrument-specific credit risk within other comprehensive income rather than earnings. FHN has not elected fair value accounting for any existing financial liabilities. Additionally, ASU 2016-01 clarifies that the need for a valuation allowance on a deferred tax asset related to available-for-sale securities should be assessed in combination with all other deferred tax assets rather than being assessed in isolation. ASU 2016-01 also makes several changes to existing fair value presentation and disclosure requirements, including a provision that all disclosures must use an exit price concept in the determination of fair value. ASU 2016-01 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Transition will be through a cumulative effect adjustment to retained earnings for equity investments with readily determinable fair values. Equity investments without readily determinable fair values, for which the accounting election is made, will have any initial fair value marks recorded through earnings prospectively after adoption. Upon adoption, FHN will reclassify all equity investments out of available-for-sale securities, leaving only debt securities within this classification. FHN has evaluated the nature of its current equity investments and determined that substantially all qualify for the election available to assets without readily determinable fair values, including its holdings of Visa Class B shares. Accordingly, FHN intends to apply this election and any fair value marks for these investments will be recognized through earnings on a prospective basis subsequent to adoption. FHN continues to evaluate the appropriate characteristics of “similar” instruments as well as related valuation inputs and methodologies for its equity investments without readily determinable fair values. The requirements of ASU 2016-01 related to assessment of deferred tax assets and disclosure of the fair value of financial instruments will not have a significant effect on FHN because its current accounting and disclosure practices conform to the requirements of ASU 2016-01. FHN also continues to evaluate the impact of ASU 2016-01 on other aspects of its current accounting and disclosure practices. In February 2016, the FASB issued ASU 2016-02, “Leases,” which requires a lessee to recognize in its statement of condition a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. ASU 2016-02 leaves lessor accounting largely unchanged from prior standards. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it should recognize lease expense for such leases generally on a straight-line basis over the lease term. All other leases must be classified as financing or operating leases which depends on the relationship of the lessee’s rights to the economic value of the leased asset. For finance leases, interest on the lease liability is recognized separately from amortization of the right-of-use asset in earnings, resulting in higher expense in the earlier portion of the lease term. For operating leases, a single lease cost is calculated so that the cost of the lease is allocated over the lease term on a generally straight-line basis. In transition to ASU 2016-02, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply, which would result in continuing to account for leases that commence before the effective date in accordance with previous requirements (unless the lease is modified) except that lessees are required to recognize a right-of-use asset and a lease liability for all operating leases at each reporting date based on the present value of the remaining minimum rental payments that were tracked and disclosed under previous requirements. ASU 2016-02 also requires expanded qualitative and quantitative disclosures to assess the amount, timing, and uncertainty of cash flows arising from lease arrangements. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. FHN is evaluating the impact of ASU 2016-02 on its current accounting and disclosure practices. In March 2016, the FASB issued ASU 2016-04, “Recognition of Breakage of Certain Prepaid Stored-Value Products,” which indicates that liabilities related to the sale of prepaid stored-value products are considered financial liabilities and should have a breakage estimate applied for estimated unused funds. ASU 2016-04 does not apply to stored-value products that can only be redeemed for cash, are subject to escheatment or are linked to a segregated bank account. ASU 2016-04 is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. FHN is evaluating the impact of ASU 2016-04 on its current accounting and disclosure practices. In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments,” which revises the measurement and recognition of credit losses for assets measured at amortized cost (e.g., held-to-maturity (“HTM”) loans and debt securities) and available-for-sale (“AFS”) debt securities. Under ASU 2016-13, for assets measured at amortized cost, the current expected credit loss (“CECL”) is measured as the difference between amortized cost and the net amount expected to be collected. This represents a departure from existing GAAP as the “incurred loss” methodology for recognizing credit losses delays recognition until it is probable a loss has been incurred. The measurement of current expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. Additionally, current disclosures of credit quality indicators in relation to the amortized cost of financing receivables will be further disaggregated by year of origination. ASU 2016-13 leaves the methodology for measuring credit losses on AFS debt securities largely unchanged, with the maximum credit loss representing the difference between amortized cost and fair value. However, such credit losses will be recognized through an allowance for credit losses, which permits recovery of previously recognized credit losses if circumstances change. ASU 2016-13 also revises the recognition of credit losses for purchased financial assets with a more-than insignificant amount of credit deterioration since origination (“PCD assets”). For PCD assets, the initial allowance for credit losses is added to the purchase price. Only subsequent changes in the allowance for credit losses are recorded as a credit loss expense for PCD assets. Interest income for PCD assets will be recognized based on the effective interest rate, excluding the discount embedded in the purchase price that is attributable to the acquirer’s assessment of credit losses at acquisition. Currently, credit losses for purchased credit-impaired assets are included in the initial basis of the assets with subsequent declines in credit resulting in expense while subsequent improvements in credit are reflected as an increase in the future yield from the assets. The provisions of ASU 2016-13 will be generally adopted through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in the year of adoption. Prospective implementation is required for debt securities for which an other-than-temporary-impairment (“OTTI”) had been previously recognized. Amounts previously recognized in accumulated other comprehensive income (“AOCI”) as of the date of adoption that relate to improvements in cash flows expected to be collected will continue to be accreted into income over the remaining life of the asset. Recoveries of amounts previously written off relating to improvements in cash flows after the date of adoption will be recorded in earnings when received. A prospective transition approach will be used for existing PCD assets where, upon adoption, the amortized cost basis will be adjusted to reflect the addition of the allowance for credit losses. Thus, an entity will not be required to reassess its purchased financial assets that exist as of the date of adoption to determine whether they would have met at acquisition the new criteria of more-than-insignificant credit deterioration since origination. An entity will accrete the remaining noncredit discount (based on the revised amortized cost basis) into interest income at the effective interest rate at the adoption date. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted in fiscal years beginning after December 15, 2018. FHN is still evaluating the impact of ASU 2016-13 on its current accounting and disclosure practices. In August 2016, the FASB issued ASU 2016-15, “Classification of Certain Cash Receipts and Cash Payments,” which clarifies multiple cash flow presentation issues including providing guidance as to classification on the cash flow statement for certain cash receipts and cash payments where diversity in practice exists. ASU 2016-15 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The provisions of ASU 2016-15 will be applied retroactively and will result in proceeds from bank-owned life insurance (“BOLI”) being classified as an investing activity rather than their prior classification as an operating activity. In March 2017, the FASB issued ASU 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost” which requires the disaggregation of the service cost component from the other components of net benefit cost for pension and postretirement plans. Service cost must be included in the same income statement line item as other compensation-related expenses. All other components of net benefit cost are required to be presented in the income statement separately from the service cost component, with disclosure of the line items where these amounts are recorded. The presentation requirements of ASU 2017-07 must be applied retrospectively and adoption is required for annual periods beginning after December 15, 2017, including interim periods within those annual periods. FHN’s disclosures for pension and postretirement costs provide details of the service cost and all other components for expenses recognized for its applicable benefit plans. These amounts are currently included in Employee compensation, incentives, and benefits expense in the Consolidated Condensed Statements of Income. Upon adoption of ASU 2017-07 FHN will reclassify the expense components other than service cost into All other expense and revise its disclosures accordingly. The amounts to be reclassified are presented in Note 11—Pension, Savings, and Other Employee Benefits in this Quarterly Report on Form 10-Q for the quarter ended June 30, 2017 and in Note 18—Pension, Savings, and Other Employee Benefits in Exhibit 13 to FHN’s Annual Report on Form 10-K for the year ended December 31, 2016 . In March 2017, the FASB issued ASU 2017-08, “Premium Amortization on Purchased Callable Debt Securities” which shortens the amortization period for securities that have explicit, noncontingent call features that are callable at fixed prices and on preset dates. In contrast to the current requirement for premium amortization to extend to the contractual maturity date, ASU 2017-08 requires the premium to be amortized to the earliest call date. ASU 2017-08 does not change the amortization of discounts, which will continue to be amortized to maturity. The new guidance does not apply to debt securities where the prepayment date is not preset or the price is not known in advance, which includes debt securities that qualify for amortization based on estimated prepayment rates. ASU 2017-08 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018 with early adoption permitted. Transition is accomplished through a cumulative-effect adjustment directly to retained earnings as of the beginning of the year of adoption. Based upon the current composition of its debt securities portfolios, FHN does not anticipate a significant effect upon adoption.
