ANNUAL REPORT 2017 CORPORATE OVERVIEW Our Commitment At First Horizon National Corp. we are committed to our customers, our people, our communities and our shareholders. We demonstrate that commitment through financial performance and corporate responsibility. We make investments that benefit our stakeholders because when they prosper, so do we. In 2017 we continued to make progress toward a future of sustained success – a future based on our 154-year history of earning the trust of Tennesseans, on our core regional banking and fixed income businesses, on the dedication of our 6,000 employees, on our support for the communities we serve and on the confidence of our shareholders. Our People We know that a company is only as strong as its people. We seek to attract, develop and retain the best people and empower them to serve our customers in exceptional ways. Our employee focus and our distinctive corporate culture – Firstpower – have earned us national recognition as one of the best companies to work for in America. Firstpower promotes accountability, adaptability, integrity and relationships, the pillars of our culture. First Horizon has been recognized as an outstanding employer by American Banker and Working Mother magazines and the National Association for Female Executives. Our Core Businesses Regional banking: First Tennessee Bank has provided financial services in local communities since 1864. Today we have more than 300 offices across the southern U.S. We have the top deposit market share in Tennessee, according to the latest FDIC figures. Our focus on consistently offering a distinctive customer experience has resulted in one of the highest customer retention rates of any bank in the country. Personal service, advanced technology and helpful employees set First Tennessee apart. We are consistently named best bank in newspaper reader surveys in the communities we serve. In 2017 we closed our merger with Capital Bank and added to our growing presence in the Carolinas, Virginia and Florida – our Mid-Atlantic region. In 2014 we opened an office in Houston, Texas that continues to excel. In these new markets our services include commercial real estate, private client, commercial banking, wealth management and corporate and commercial lending. FTB Advisors, our wealth management team, offers access to the same products available from national brokerage firms delivered by local professionals who care about our communities and customers. Our goal is to be easy to do business with, to be the best at serving customers in all our business lines. We offer a full range of products, convenient locations and hours, and the latest advances in mobile banking. We’ve been recognized by InformationWeek magazine as one of the most innovative users of technology. In fact, First Tennessee was the first bank in our markets to offer mobile banking for commercial customers and mobile check deposit to consumers, and our customers have enthusiastically embraced these new ways of doing business. Above all, our knowledgeable employees strive to be proactive and help customers manage their money and make sound financial decisions for the future. That adds up to a distinctive customer experience – our competitive advantage. More information is available at www.FirstTennessee.com, www.CapitalBank-US.com or at any of our convenient offices. Fixed income: FTN Financial is an industry leader in fixed income sales, trading and strategies for institutional customers in the U.S. and abroad.

FTN Financial also provides investment services and balance sheet management solutions. With 28 offices across the country, FTN Financial provides a broad spectrum of financial services for the investment and banking communities through the integration of traditional capital markets securities activities, loan sales, portfolio advisory services and derivative sales.

More information can be found at www.FTNFinancial.com. Our Communities We share the hopes of our neighbors for a better place to live and work. In addition to the financial services we provide and the jobs and spending we bring to local economies, we express our corporate citizenship through our volunteer spirit and community investment. Our employee volunteer program has received national recognition from the Financial Services Roundtable. In 2017, our volunteers donated more than 24,000 hours of community service, and we supported their efforts through leadership grants to nearly 200 nonprofits and more than 380 matching gifts. In 2017, our First Tennessee Community Development Fund awarded grants to 150 organizations to support low to moderate income residents in the communities we serve. We established the First Tennessee Foundation in 1993 to invest in the communities we serve. Through this private charitable foundation, we make donations in a way that engages our employees, responds inclusively to needs and promotes progress and prosperity throughout Tennessee and across our footprint. Since its inception, the First Tennessee Foundation has donated more than $80 million to meet community needs. In 2017, our Foundation awarded grants to nearly 600 nonprofits. More information can be found at www.FirstTennesseeFoundation.com. We focus our community investment in key areas: Financial literacy and education: To plant the seeds of success, we give to help educate young people. Our volunteers provide tutoring to students, with a special emphasis on financial literacy. The Tennessee Financial Literacy Commission has named us an outstanding corporate partner. We have partnered with Operation HOPE, a national nonprofit, to offer free credit counseling workshops at several of our locations. We support local schools, colleges and universities across our footprint. Economic development: To encourage jobs and growth, we support Chambers of Commerce, regional development initiatives and small business resources. We have helped secure grants for nonprofits to develop hundreds of units of affordable housing. We have developed flexible banking products to expand access for the underserved. Health and human services: We are one of the largest United Way supporters in Tennessee. Our executives serve in community-wide leadership roles, and our employees volunteer in agencies working to better our communities. To ensure that our employees and neighbors have access to top-quality care, First Tennessee supports healthcare institutions throughout the state. Arts and culture: Because art plays a vital role in a healthy community, the First Tennessee Foundation is a long-time supporter. Arts organizations, museums, theaters, symphonies and cultural institutions throughout the state receive support. Our World Concern for environmental sustainability is part of the way we do business. In addition to the company’s commitment, the First Tennessee Foundation supports green projects across the state such as nature conservancy, bike trails and historic preservation. Examples of our sustainable practices: • In 2017, our recycling program with Cintas Document Management helped us save the equivalent of an estimated 24,000 trees, enough energy to supply 365 homes a year, nearly 23 million gallons of water, nearly 2 million pounds of solid waste and the equivalent of the greenhouse gasses produced by 519 cars each year. • We continue to use less paper and cardboard and recycle an average of 5 tons of paper a month. • To reduce water consumption, we use indigenous plants for landscaping at all new facilities. • Buildings are designed with a goal of enhancing energy efficiency and sustainability, from window blinds to the heating and cooling systems to motion-sensor lighting and low-volume flush valves and faucets. • Recycled products are used in carpeting, wallpaper, fabrics and parking abutments. • At our facilities, air conditioning equipment uses environmentally friendly refrigerant, and we continue to upgrade aging equipment at our locations, using environmentally friendly refrigerant and improving air quality and efficiency. • Our First Operations West facility generates approximately $14,000 in savings per year in energy consumption, via onsite solar panels. • At our Corporate Headquarters, we use water reclamation to reduce the amount of water used during the summer months by taking condensate water and injecting it back into our cooling towers. • Enterprise-wide, we are replacing all light sources with energy efficient LED lamps and fixtures. Our Promise We promise to be the best at serving our customers, one opportunity at a time. We will continue to advance our people, support our communities and reward our investors. Carrying on our 154-year tradition, First Horizon is building for a bright future. CHAIRMAN’S LETTER SIGNIFICANT TRANSFORMATION, SMOOTH INTEGRATION Dear Fellow First Horizon Shareholders: First Horizon experienced a transformational year in 2017, closing our merger with Capital Bank – the largest in our company’s history. The merger resulted in a $41 billion organization and prepares us for growth in very attractive markets. The Capital Bank merger also positions us to continue to invest in industry-leading products and services to meet evolving customer needs. Thanks to the hard work and dedication of our people, we are on track to substantially complete the integration in the second quarter of 2018. First Horizon’s merger with Capital Bank created the fourth-largest regional bank headquartered in the Southeast, with more than 300 branches in eight states. Our company now has a meaningful presence in attractive, high-growth markets in the Carolinas and South Florida, along with an expanded footprint in Middle Tennessee. We believe these markets, which have above-average population growth and robust economies, will be significant performance drivers for our company. Capital Deployment Actions and Enhanced Merger Economics When we announced our merger with Capital Bank in May 2017, we estimated cost savings of $65 million through vendor savings, technology, corporate functions and bank operations. Within six months we increased that amount significantly to $85 million. We now estimate revenue synergies of $25 million to $30 million over the next two to three years. Revenue synergies include: Commercial • Selling a full product suite across a larger client base • Expanding treasury management services and clients • Growing our balance sheet with a higher lending capacity • Generating organic growth through expanded geographic opportunities Consumer • Increasing branch deposit-gathering efficiencies in the Capital Bank network • Introducing private client / wealth management services to the Capital Bank network • Expanding Capital Bank mortgage platforms in the First Horizon network • Achieving peer-level credit card penetration In 2017, we completed the acquisition of Coastal Securities, a national leader in the trading, securitization and analysis of Small Business Administration loans. Coastal also trades United States Department of Agriculture loans and fixed income products and provides municipal underwriting and advisory services. The Coastal Securities transaction broadened depth and diversity for product offerings in the fixed income business. Also in 2017, First Tennessee Bank National Association acquired PMC, a leading provider of institutional debt capital and commercial mortgage loan servicing, which expanded the capabilities of our commercial real estate platform. In addition to deploying capital through acquisitions, we increased our annual common dividend rate by 29 percent to $0.36 per share, and in early 2018 we increased it again by 33 percent to $0.48 per share. Innovation, technology spur new opportunities The rate of technological change in financial services is unprecedented. As fintech continues to transform our industry, First Horizon is prepared to meet new challenges and pursue new opportunities. We recognize the changing landscape of banking, driven by customers seeking expanded digital banking services. As new, disruptive technologies are introduced to the market, we will continue to offer our customers leading edge solutions to their day-to-day business challenges. We have upgraded our digital banking platform and our mobile app, and we are engaging with technology firms to optimize transactions as customer preferences shift. Our improvements have generated impressive results, and in 2017 First Tennessee was ranked by Money as the top bank in Tennessee. Our company is dedicated to exploring ways we can utilize technology and innovation to offer differentiated service to existing customers, attract new ones and operate more efficiently. We believe our adaptability will enable us to thrive in an ever-changing environment. Strong foundation, solid growth First Horizon’s impressive performance during 2017 was driven by strong fundamentals. We demonstrated healthy growth in our balance sheet, maintained stable credit quality, and remain well positioned to deliver on strategic priorities and create long-term value for our shareholders. During the past year, we generated solid growth in loans and deposits at First Tennessee. From 2016 to 2017, our regional bank average loans grew 13 percent, average deposits were up 11 percent, and revenue was up 12 percent from increased net interest income and higher fee income. Balance sheet growth was driven by our focus on specialty lending areas that are higher return businesses and generate strong levels of economic profit. Asset quality trends remained strong, reflecting disciplined underwriting from our experienced bankers. Despite challenging conditions that led to lower sales volumes in 2017, FTN Financial remains an industry leader in fixed income, sales, trading and strategies for institutional customers. In recent years, FTN Financial has transacted business with about 40 percent of all domestic depositories with portfolios over $100 million. Strategic focus, increased performance As we celebrate our 154th year, we remain committed to strengthening our customer relationships, expanding our presence across our markets and improving and growing all lines of business. Commitment to our Bonefish strategy is producing long-term earnings power and solid returns for our shareholders. By concentrating on efficiency, productivity and economic profit, First Horizon is a more responsive and higher return company. The efficiency model enables us to work smarter to streamline processes and perform sharper to increase profitability. As we engage in an ever-evolving industry, we have continued to increase loans and deposits, we have maintained our No. 1 market share position in Tennessee, and we are pursuing new growth opportunities in new markets. Our investments over the past few years in our specialty lending areas such as franchise finance, music industry banking and healthcare continue to deliver strong results. Our experienced bankers who are leading these segments are helping our company grow its business throughout our footprint and with customers across the country. We expect to achieve our Bonefish ROTCE target by year-end 2018. Our merger with Capital Bank accelerates our hitting the targets by bringing scale and efficiency to our company. Tax reform and potential rate hikes will further accelerate reaching these goals. Exceptional culture, continued excellence Building on our exceptional culture and our tradition of excellence, First Horizon is consistently recognized as one of the top workplaces in the country. We focus on attracting, recruiting and retaining the best and brightest employees who are dedicated to providing differentiated service that sets us apart. Recently we distributed $1,000 bonuses to approximately 70 percent of our employees, increased the minimum pay level of employees to $15 an hour, and contributed $16.5 million to our Foundation. Our commitment to diversity and inclusion has created a culture where employees are engaged and empowered. During the past year we were once again named one of the Top 60 Companies for Executive Women by the National Association for Female Executives, and one of the nation’s top employers by American Banker and Working Mother magazines. In 2017, First Horizon was also named one of the 25 Best Companies for Multicultural Women by Working Mother magazine, and First Tennessee was honored by American Banker as No. 5 on its list of Top 10 Most Reputable Banks in the nation. The drivers of our success are our dedicated employees, whose contributions create engaging workplaces and vibrant communities. During 2017, our employees logged more than 24,000 hours of volunteer service at charitable and civic organizations and participated in nearly 5,300 unique volunteer events. Our corporate citizenship delivers a similarly powerful impact. In 2017, the First Tennessee Foundation awarded grants to nearly 600 nonprofits across our footprint, and our First Tennessee Community Development Fund awarded grants to 150 organizations that support the needs of low to moderate income communities. These combined contributions reached nearly $11 million in the communities we serve. When our communities thrive we thrive, and our actions prove our commitment to this belief. Harnessing momentum, maximizing opportunities We enter 2018 with great momentum, fueled by the transformational merger with Capital Bank. The power of these two brands will open up exciting new avenues for us and increase opportunities for growth. With our expanded footprint and capabilities, we are able to offer the same products and services from Houston to Memphis, from Nashville to Knoxville, from Raleigh to Naples. Our growing presence reflects a company that is stronger than ever and prepared for an outstanding future. We are proud of our impressive gains of the past year and excited about the opportunities ahead. As we build on the momentum of our legacy of 154 years, we remain dedicated to providing differentiated service for our customers and increasing returns for shareholders. Thank you to our employees for their dedication, to our customers for their trust, and to our communities for their support. We appreciate the investment and confidence of our shareholders, and we will continue to work hard to justify that trust as we build a bright future together. Sincerely, D. Bryan Jordan Chairman, President and CEO First Horizon National Corp.

FHN is the parent company of First Tennessee Bank National Association (“FTBNA”). FTBNA’s principal divisions and subsidiaries operate under the brands of First Tennessee Bank, Capital Bank, FTB Advisors, and FTN Financial. FHN offers regional banking, wealth management and capital market services through the First Horizon family of companies. First Tennessee Bank, Capital Bank, and FTB Advisors provide consumer and commercial banking and wealth management services. FTN Financial (“FTNF”), which operates partly through a division of FTBNA and partly through subsidiaries, is an industry leader in fixed income sales, trading, and strategies for institutional clients in the U.S. and abroad. FTBNA has over 350 banking offices in eight southeastern U.S. states, and FTNF has 28 offices in 18 states across the U.S. FHN is composed of the following operating segments: • Regional banking segment offers financial products and services, including traditional lending and deposit taking, to consumer and commercial customers in Tennessee, North Carolina, South Carolina, Florida and other selected markets. Regional banking also provides investments, financial planning, trust services and asset management, mortgage banking, 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. • 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. • 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, gain/(loss) on extinguishment of debt, and acquisition- and integration-related costs. • 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. On November 30, 2017, FHN completed its acquisition of Capital Bank Financial Corporation (“CBF”) and its subsidiaries, including Capital Bank Corporation for an aggregate of 92,043,171 shares of FHN common stock and $423.6 million in cash in a transaction valued at $2.2 billion. CBF operated 178 branches in North and South Carolina, Tennessee, Florida and Virginia at the time of closing. On October 2, 2017, FTBNA acquired the operations and certain assets of Professional Mortgage Company, Inc. (“PMC”). PMC was a provider of institutional debt capital and commercial mortgage loan servicing. Eleven professionals joined FTBNA’s commercial real estate (“CRE”) team as a result of the transaction, expanding the capabilities of its CRE platform. On April 3, 2017, FTNF acquired substantially all of the assets and assumed substantially all of the liabilities of Coastal Securities, Inc. (“Coastal”), a national leader in the trading, securitization, and analysis of Small Business Administration (“SBA”) loans, for approximately $131 million in cash. Coastal, which was based in Houston, TX, FIRST HORIZON NATIONAL CORPORATION 3 also traded United States Department of Agriculture (“USDA”) loans and fixed income products and provided municipal underwriting and municipal advisory services to its clients. Coastal’s government-guaranteed loan products were combined with FTNF’s existing SBA trading activities to establish an additional major product sector for FTNF. On September 16, 2016, FTBNA acquired $537.4 million of unpaid principal balance (“UPB”) in restaurant franchise loans from GE Capital. The acquired loans were combined with existing FTBNA relationships to establish a franchise finance specialty banking business. On October 2, 2015, FHN completed its acquisition of TrustAtlantic Financial Corporation (“TrustAtlantic Financial” or “TAF”), and its wholly owned bank subsidiary TrustAtlantic Bank (“TAB”), for an aggregate of 5.1 million shares of FHN common stock and $23.9 million in cash in a transaction valued at $96.7 million. The fair value of the acquired assets totaled $445.3 million, including $281.9 million in loans. FHN also assumed $344.1 million of TAB deposits. In relation to all acquisitions, FHN’s operating results include the operating results of the acquired assets and assumed liabilities subsequent to the acquisition date. Refer to Note 2 - Acquisitions and Divestitures for additional information. For the purpose of this management’s discussion and analysis (“MD&A”), earning assets have been expressed as averages, unless otherwise noted, and loans have been disclosed net of unearned income. The following financial discussion should be read with the accompanying audited Consolidated Financial Statements and Notes in this report. ADOPTION OF ACCOUNTING UPDATES Issued in February 2018, ASU 2018-02, “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income,” provides an election for reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects solely resulting from the Tax Cuts and Jobs Act (“the Tax Act”). The stranded tax effects were created because current accounting requirements indicate that all changes in deferred tax assets and liabilities due to changes in enacted tax rates be recorded through tax provision, even when the deferred tax asset or liability was originally created with an offset to accumulated comprehensive income. For FHN, this includes net deferred tax assets related to net unrealized losses on available-for-sale (“AFS”) securities, net actuarial losses for pension and postretirement plans, and the effective portion of cash flow hedging activities. The provisions of ASU 2018-02 do not apply to past or future changes in tax rates. Adoption of ASU 2018-02 is required for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted in any interim period for which financial statements have not yet been issued. FHN elected early adoption as of December 31, 2017 and made a reclassification of $57.5 million from accumulated other comprehensive income to retained earnings. Non-GAAP Measures Certain measures are included in the narrative and tables in this MD&A that are “non-GAAP”, meaning (under U.S. financial reporting rules) they are not presented in accordance with generally accepted accounting principles (“GAAP”) in the U.S. and also are not codified in U.S. banking regulations currently applicable to FHN. Although other entities may use calculation methods that differ from those used by FHN for non-GAAP measures, FHN’s management believes such measures are relevant to understanding the capital position or financial results of FHN. Non-GAAP measures are reported to FHN’s management and Board of Directors through various internal reports. Presentation of regulatory measures, even those which are not GAAP, provide a meaningful base for comparability to other financial institutions subject to the same regulations as FHN, as demonstrated by their use by banking regulators in reviewing capital adequacy of financial institutions. Although not GAAP terms, these regulatory measures are not considered “non-GAAP” under U.S. financial reporting rules as long as their presentation conforms to regulatory standards. Regulatory measures used in this MD&A include: common equity tier 1 capital, 4 FIRST HORIZON NATIONAL CORPORATION generally defined as common equity less goodwill, other intangibles, and certain other required regulatory deductions; tier 1 capital, generally defined as the sum of core capital (including common equity and instruments that cannot be redeemed at the option of the holder) adjusted for certain items under risk based capital regulations; and risk-weighted assets (“RWA”), which is a measure of total on- and off-balance sheet assets adjusted for credit and market risk, used to determine regulatory capital ratios. The non-GAAP measures presented in this filing are return on average tangible common equity (“ROTCE”), tangible common equity to tangible assets and adjusted tangible common equity to risk-weighted assets. Refer to table 33 for a reconciliation of the non-GAAP to GAAP measures and presentation of the most comparable GAAP items. FORWARD-LOOKING STATEMENTS This MD&A contains forward-looking statements with respect to FHN’s beliefs, plans, goals, expectations, and estimates. Forward-looking statements are not a representation of historical information but instead pertain to future operations, strategies, financial results, or other developments. The words “believe,” “expect,” “anticipate,” “intend,” “estimate,” “should,” “is likely,” “will,” “going forward,” and other expressions that indicate future events and trends identify forward-looking statements. Forward-looking statements are necessarily based upon estimates and assumptions that are inherently subject to significant business, operational, economic and competitive uncertainties and contingencies, many of which are beyond FHN’s control, and many of which, with respect to future business decisions and actions (including acquisitions and divestitures), are subject to change. Examples of uncertainties and contingencies include, among other important factors: global, general and local economic and business conditions, including economic recession or depression; the stability or volatility of values and activity in the residential housing and commercial real estate markets; potential requirements for FHN to repurchase, or compensate for losses from, previously sold or securitized mortgages or securities based on such mortgages; potential claims alleging mortgage servicing failures, individually, on a class basis, or as master servicer of securitized loans; potential claims relating to participation in government programs, especially lending or other financial services programs; expectations of and actual timing and amount of interest rate movements, including the slope and shape of the yield curve, which can have a significant impact on a financial services institution; market and monetary fluctuations, including fluctuations in mortgage markets; inflation or deflation; customer, investor, competitor, regulatory, and legislative responses to any or all of these conditions; the financial condition of borrowers and other counterparties; competition within and outside the financial services industry; geopolitical developments including possible terrorist activity; natural disasters; effectiveness and cost-efficiency of FHN’s hedging practices; technological changes; fraud, theft, or other incursions through conventional, electronic, or other means affecting FHN directly or affecting its customers, business counterparties or competitors; demand for FHN’s product offerings; new products and services in the industries in which FHN operates; the increasing use of new technologies to interact with customers and others; and critical accounting estimates. Other factors are those inherent in originating, selling, servicing, and holding loans and loan-based assets, including prepayment risks, pricing concessions, fluctuation in U.S. housing and other real estate prices, fluctuation of collateral values, and changes in customer profiles. Additionally, the actions of the Securities and Exchange Commission (“SEC”), the Financial Accounting Standards Board (“FASB”), the Office of the Comptroller of the Currency (“OCC”), the Board of Governors of the Federal Reserve System (“Federal Reserve” or “Fed”), the Federal Deposit Insurance Corporation (“FDIC”), the Financial Industry Regulatory Authority (“FINRA”), the U.S. Department of the Treasury (“U.S. Treasury”), the Municipal Securities Rulemaking Board (“MSRB”), the Consumer Financial Protection Bureau (“CFPB”), the Financial Stability Oversight Council (“Council”), the Public Company Accounting Oversight Board (“PCAOB”), and other regulators and agencies; pending, threatened, or possible future regulatory, administrative, and judicial outcomes, actions, and proceedings; current or future Executive orders; changes in laws and regulations applicable to FHN; and FHN’s success in executing its business plans and strategies and managing the risks involved in the foregoing, could cause actual results to differ, perhaps materially, from those contemplated by the forward-looking statements. FHN assumes no obligation to update or revise any forward-looking statements that are made in this Annual Report to Shareholders for the period ended December 31, 2017 of which this MD&A is a part or otherwise from time to time. Actual results could differ and expectations could change, possibly materially, because of one or more factors, including those presented in this Forward-Looking Statements section, in other sections of this FIRST HORIZON NATIONAL CORPORATION 5 MD&A, in other parts of and exhibits to this Annual Report to Shareholders, or in FHN’s Annual Report on Form 10-K for the period ended December 31, 2017 into which this MD&A has been incorporated, and in documents incorporated into the Form 10-K. FINANCIAL SUMMARY – 2017 COMPARED TO 2016 FHN reported net income available to common shareholders of $159.3 million, or $.65 per diluted share, compared to net income of $220.8 million, or $.94 per diluted share in 2016. The decline in net income available to common shareholders in 2017 was due to higher noninterest expense, an increase in income taxes, and a decrease in noninterest income, somewhat mitigated by an increase in net interest income and a decline in the provision for loan losses. Various factors significantly impacted reported earnings in 2017 including acquisitions and other strategic transactions expected to boost growth, returns and profitability. Additional factors affecting reported results were increased interest rates, tax reform, certain legacy mortgage matters, and the steady economic environment. During 2017, FHN continued to execute on strategic priorities by strengthening core businesses, controlling costs and prudently managing the balance sheet. FHN invested in its core businesses by focusing on higher-return specialty lending areas; making strategic hires; upgrading digital banking platforms; and expanding into growth markets both organically and through acquisitions. Management successfully deployed capital through profitable loan growth, dividend increases, and acquisitions. FHN completed three acquisitions in 2017, significantly strengthening FHN’s ability to grow and improve returns over the long-term. In November 2017, FHN closed the acquisition of CBF, a $10 billion bank headquartered in North Carolina. The CBF acquisition expands FHN’s presence in high-growth, attractive geographic markets; provides scale and efficiency; and, accelerates the achievement of FHN’s long-term financial goals on return, profitability and productivity. In April 2017, FHN completed the purchase of Coastal, a national leader in the trading, securitization and analysis of SBA loans. The Coastal transaction provided a broadened depth and diversity for product offerings in the fixed income business. In October 2017, FHN closed on its purchase of PMC, a leading provider of institutional debt capital and commercial mortgage loan servicing which will expand the capabilities of FHN’s commercial real estate platform. In December 2017, congress enacted the Tax Act, reducing the federal statutory tax rate from 35 percent to 21 percent for FHN. The rate reduction on January 1, 2018 should benefit financial results in the future; however, the enactment of the rate reduction affected FHN’s deferred tax balances and negatively impacted FHN’s 2017 operating results. Earlier in 2017, FHN recognized favorable effective tax rate adjustments primarily associated with the reversal of a capital loss deferred tax valuation allowance which somewhat offset the overall increase in provision for income taxes. The economic environment remained steady-to-improving in 2017 with GDP growth throughout the year, low unemployment rates, and muted inflation. Organic loan growth and additional loans added through acquisitions coupled with a modest increase in short-term interest rates bolstered FHN’s net interest income (“NII”) and net interest margin (“NIM”); favorably impacting revenues in 2017 relative to the prior year. While the economic improvement positively impacted FHN’s NII in 2017, higher rates and a lack of interest rate volatility negatively impacted fee income from FTNF due to the counter-cyclical impact of the interest rate environment which led to lower fixed income sales revenue in 2017. Asset quality trends were stable in 2017 reflecting continued strong underwriting standards. Allowance for loan losses continued to decline, decreasing 6 percent in 2017 as a result of the run-off of non-strategic loan balances partially offset by organic loan growth. Net charge-offs and nonperforming loans declined 35 percent and 10 percent, respectively, both reflecting strong credit quality in 2017. The addition of loans as a result of the CBF acquisition increased the diversification of the loan portfolio across geographic markets and various lending areas, including higher-return specialty areas. Return on average common equity (“ROE”) and ROTCE for 2017 were 6.18 percent and 7.23 percent, respectively, compared to 9.60 percent and 10.59 percent in 2016. Return on average assets (“ROA”) was 6 FIRST HORIZON NATIONAL CORPORATION .59 percent in 2017 compared to .87 percent in 2016. The tangible common equity to tangible assets ratio was 6.57 percent in 2017 compared to 7.42 percent in 2016. Common equity tier 1, Tier 1, Total capital, and Leverage ratios were 8.88 percent, 9.83 percent, 11.10 percent, and 10.31 percent on December 31, 2017, compared to 9.94 percent, 11.17 percent, 12.24 percent, and 9.35 percent, respectively, on December 31, 2016. Total period-end assets were $41.4 billion on December 31, 2017, a 45 percent increase from $28.6 billion on December 31, 2016. Total period-end equity was $4.6 billion on December 31, 2017, up from $2.7 billion on December 31, 2016. BUSINESS LINE REVIEW – 2017 COMPARED TO 2016 Regional Banking Pre-tax income within the regional banking segment increased 36 percent to $456.1 million in 2017 from $336.1 million in 2016. The increase in pre-tax income was primarily driven by higher revenue and a decline in loan loss provision, which more than offset an increase in expenses. Total revenue increased 12 percent, or $116.7 million, to $1.1 billion in 2017, from $990.8 million in 2016, driven by an increase in NII. The increase in NII was largely due to the favorable impact of higher interest rates on loans, higher average balances of commercial loans and noninterest-bearing deposits, as well as loan and deposit growth associated with the CBF acquisition. Noninterest income was $258.6 million and $249.0 million in 2017 and 2016, respectively. The increase in noninterest income was largely driven by a $5.6 million increase in brokerage, management fees, and commission income from the Bank’s wealth management group due to increases in recurring revenue driven primarily by growth in FHN’s advisory business and favorable market conditions. Additionally, increases in fees from deposit transactions and cash management activities, mortgage banking income, and bankcard income also contributed to the increase in noninterest income in 2017. Deposit transactions and cash management activities increased $2.0 million in 2017 largely driven by higher fee income associated with cash management activities, which offset a decline in non-sufficient funds (“NSF”)/overdraft fees driven by changes in consumer behavior and a modification of billing practices. Fees associated with mortgage banking activities increased $1.7 million in 2017 and were primarily related to FHN’s Community Reinvestment Act (“CRA”) initiatives. Bankcard income increased $1.1 million relative to the prior year primarily due to an increase in interchange income as a result of increased volume due to the CBF acquisition. FHN recognized $.4 million in net securities gains for 2017 primarily resulting from the call of a $4.4 million held-to-maturity municipal bond in second quarter 2017. Gains on the sale of fixed assets decreased $2.0 million in 2017 and fees from derivative transactions decreased $2.0 million both reducing noninterest income in 2017 compared to 2016. Provision expense was $21.6 million in 2017 down from $38.9 million in 2016. The net decrease in provision in 2017 compared to the prior year was primarily due to continued strong performance in both the commercial and consumer portfolios. The provision in 2017 was favorably affected by historically lower net charge-offs which continue to drive lower loss rates. Noninterest expense increased 2 percent to $629.7 million in 2017 from $615.8 million in 2016. The increase in expenses was primarily driven by an increase in personnel-related expenses due to strategic hires in expansion markets and specialty areas, higher incentive expense associated with loan/deposit growth, retention initiatives, and $19.1 million attributable to CBF activities ($10.7 million of which relates to a 27 percent increase in headcount for one month). Additionally, FHN recognized $4.1 million in special employee bonuses which also contributed to the increase in personnel expense in 2017. To a lesser extent FDIC premium expense, occupancy, computer software, intangible asset amortization, and expenses associated with equipment rentals, deprecation and maintenance all increased relative to 2016, negatively impacting regional banking expenses. The increase in FDIC premium expense was due in large part to organic and acquisition-related balance sheet growth, as well as the net loss recognized in fourth quarter 2017. The other expense categories increased primarily due to the CBF acquisition. The regional banking segment recognized a $15.9 million net decline in loss accruals related to legal matters favorably impacting expenses in 2017. Additionally, a recovery from a vendor recognized in first quarter 2017 related to previous overbillings also positively impacted expenses in 2017. FIRST HORIZON NATIONAL CORPORATION 7 Fixed Income Pre-tax income in the fixed income segment was $24.2 million in 2017 compared to $50.5 million in 2016. The decline in results in 2017 was driven by lower fee income, somewhat offset by a decline in expenses and an increase in NII. NII increased from $10.8 million in 2016 to $18.0 million in 2017, primarily driven by an increase in loans held- for-sale as a result of the Coastal acquisition. Fixed income product revenue decreased 24 percent to $173.9 million in 2017 from $229.7 million in 2016, as average daily revenue (“ADR”) declined to $696 thousand in 2017 from $919 thousand in 2016. This decline reflects lower activity due to challenging market conditions (interest rate increases, a flattening yield curve, and low levels of market volatility). Other product revenue was $43.2 million in 2017 up from $39.7 million in the prior year, primarily driven by increases in fees from loan sales, which more than offset declines in fees from derivative sales and portfolio advisory services. Noninterest expense decreased 8 percent, or $18.6 million, to $210.9 million in 2017 from $229.6 million in 2016. The expense decline during 2017 was primarily the result of lower variable compensation associated with the decrease in fixed income sales revenue in 2017. A portion of the expense decline was somewhat offset by an increase in legal fees and increased amortization and other expenses associated with the Coastal acquisition. Corporate The pre-tax loss for the corporate segment was $189.4 million and $104.4 million for 2017 and 2016, respectively. Net interest expense was $58.9 million in 2017 compared to $65.9 million in 2016. The improvement in net interest expense for 2017 was largely driven by a higher yielding securities portfolio. Noninterest income (including securities gain/losses) was $8.9 million in 2017, compared to $20.4 million in 2016. Noninterest income declined in 2017 compared to the prior year due in large part to a $14.3 million loss from the repurchase of equity securities previously included in a financing transaction. Additionally, net gains on the sale of securities decreased $1.1 million in 2017, largely the result of a $1.7 million gain from an exchange of approximately $294 million of available-for-sale (“AFS”) debt securities recognized in 2016. Deferred compensation income, which fluctuates with changes in the market value of the underlying investments and is mirrored by changes in deferred compensation expense which is included in personnel expense, increased $3.3 million in 2017 partially mitigating the decline in noninterest income. Noninterest expense was $139.4 million in 2017 compared to $58.9 million in 2016. The increase in noninterest expense was largely due to a $53.6 million increase in acquisition- and integration-related expenses primarily associated with the CBF and Coastal acquisitions, $5.7 million of special employee bonuses, and $8.8 million of charitable contributions to the First Tennessee Foundation made in 2017. To a lesser extent, higher deferred compensation expense also contributed to the expense increase in 2017, but was offset by $6.5 million of deferred compensation BOLI gains recognized in 2017. Advertising and public relations expense decreased $1.7 million in 2017 due in large part to a promotional branding campaign and higher expenses associated with CRA initiatives recognized in 2016. Additionally, a $2.1 million decrease in negative valuation adjustments associated with derivatives related to prior sales of Visa Class B shares offset a portion of the overall expense increase. Non-Strategic The non-strategic segment had pre-tax income of $18.0 million in 2017 compared to $63.0 million in 2016. The decline in results was primarily driven by higher expenses and a lower loan loss provision credit in 2017 relative to the prior year, coupled with a decline in revenues. Total revenue decreased $16.2 million to $39.9 million in 2017 from $56.0 million in 2016. NII declined 19 percent to $34.3 million in 2017 consistent with the run-off of the non-strategic loan portfolios. Noninterest income (including securities gains/losses) was $5.6 million in 2017 compared to $13.7 million in 2016. The decrease in noninterest income was largely attributable to a decline in mortgage banking income due in large part to $4.4 million of recoveries recognized in 2016 associated with prior legacy mortgage servicing sales and a $1.5 million gain in 2016 related to the reversal of a contingency accrual associated with prior sales of mortgage servicing rights (“MSR”). 8 FIRST HORIZON NATIONAL CORPORATION The provision for loan losses within the non-strategic segment was a provision credit of $21.6 million in 2017 compared to a provision credit of $27.9 million in the prior year. Overall, the non-strategic segment continued to reflect stable performance combined with lower loan balances as reserves declined by $12.5 million to $35.4 in December 31, 2017, nearly all of which was in the consumer real estate portfolio. Losses remain historically low as the non-strategic segment experienced an increase in net recoveries of $5.9 million in 2017 compared to the prior year. Noninterest expense was $43.6 million in 2017 compared to $20.9 million in 2016. The increase in noninterest expense was primarily due to a $25.7 million net increase in loss accruals related to legal matters. Additionally, a smaller repurchase and foreclosure provision expense reversal related to the settlement of certain repurchase claims in 2017 relative to 2016 ($22.5 million and $32.7 million, respectively) also contributed to the increase in expense. An $11.9 million decrease in legal fees favorably impacted non-strategic expenses in 2017. INCOME STATEMENT REVIEW – 2017 COMPARED TO 2016; 2016 COMPARED TO 2015 Total consolidated revenue increased 4 percent, or $51.0 million to $1.3 billion in 2017, driven by a 16 percent increase in net interest income, which more than offset lower fee income from fixed income product revenue. Total consolidated expense increased 11 percent to $1.0 billion in 2017 from $925.2 million in 2016. The expense increase was primarily driven by an increase in acquisition-related expenses associated with the CBF and Coastal acquisitions, and to a lesser extent an increase in accruals related to loss contingencies and litigation matters. In 2016 and 2015, total consolidated revenue was $1.3 billion and $1.2 billion, respectively, largely driven by increases in net interest income and fixed income product revenue. Total consolidated expense decreased 12 percent to $925.2 million in 2016 from $1.1 billion in 2015 primarily driven by a decline in accruals related to loss contingencies and litigation matters and a mortgage repurchase provision expense reversal recognized in 2016, somewhat offset by higher personnel expense in 2016 compared to 2015. NET INTEREST INCOME Net interest income increased 16 percent to $842.3 million in 2017 from $729.1 million in 2016. On a fully taxable equivalent (“FTE”) basis, NII increased 16 percent to $855.9 million in 2017 from $740.7 million in 2016. As detailed in Table 1 – Analysis of Changes in Net Interest Income, the increase in NII was primarily driven by organic loan growth within the regional banking commercial loan portfolio, the positive impact of higher market rates on loans and other earning assets, and commercial and consumer loans added through the CBF acquisition, somewhat offset by lower average balances of consumer loans and loans to mortgage companies. An increase in loans held-for-sale (“HFS”) added through the Coastal and CBF acquisitions also improved NII in 2017 relative to 2016. The negative impact of higher market rates on deposits and other funding sources and the continued run-off of the non-strategic loan portfolios negatively impacted NII in 2017. Average earning assets were $27.5 billion and $25.2 billion in 2017 and 2016, respectively. The 9 percent increase in average earning assets in 2017 was primarily driven by organic loan growth within FHN’s regional banking activities, loans added as part of the CBF acquisition, higher average balances of excess cash held at the Federal Reserve (“Fed”) and an increase in loans held-for-sale ("HFS") associated with the Coastal and CBF acquisitions. These increases were somewhat offset by continued run-off of the non-strategic loan portfolios, a decrease in securities purchased under agreements to resell and lower average balances of fixed income trading securities relative to 2016. Net interest income was $729.1 million in 2016, a 12 percent increase from $653.7 million in 2015. On an FTE basis, NII increased to $740.7 million in 2016 from $664.4 million in 2015. The increase in NII was the result of loan growth within Regional Banking, the positive impact of higher interest rates on loans, lower long-term funding costs due to lower average balances, and a larger investment securities portfolio. These increases were partially offset by the continued run-off the non-strategic loan portfolios, the negative impact of higher market rates on deposits, lower average balances of trading securities, and a decrease in cash basis interest income in 2016 relative to 2015.

(a) The changes in interest due to both rate and volume have been allocated to change due to rate and change due to volume in proportion to the absolute and amounts of the changes in each. (b) Variances are computed on a line-by-line basis and are non-additive. For purposes of computing yields and the net interest margin, FHN adjusts net interest income to reflect tax exempt income on an equivalent pre-tax basis which provides comparability of net interest income arising from both taxable and tax-exempt sources. The consolidated net interest margin improved to 3.12 percent in 2017 from 2.94 percent in 2016. The net interest spread increased to 2.91 percent in 2017 from 2.80 percent in 2016, and the impact of free funding was 21 basis points and 14 basis points in 2017 and 2016, respectively. The improvement in NIM in 2017 relative to 2016 was largely the result of the positive impact of higher market rates and an increase in average deposits, somewhat offset by an increase in average excess cash held at the Fed during 2017. The consolidated net interest margin was 2.94 percent in 2016 compared to 2.83 percent in 2015. The positive impact of higher interest rates on loans, lower long-term funding costs, a decrease in average excess cash held at the Fed and higher average balances of loans to mortgage companies during 2016 all contributed to the increase in NIM in 2016 relative to 2015, but were somewhat mitigated by the continued run-off of the nonstrategic loan portfolios, the negative impact of higher market rates on deposits, and a decrease in cash basis interest income relative to 2015. The activity levels and related funding for FHN’s fixed income activities affect the net interest margin. Generally fixed income activities compress the margin, especially where there are elevated levels of trading inventory, because of the strategy to reduce market risk by economically hedging a portion of its inventory on the balance sheet. As a result, FHN’s consolidated margin cannot be readily compared to that of other bank holding 10 FIRST HORIZON NATIONAL CORPORATION companies.

(a) 2016 increase driven by payoff of lower yielding municipal bonds in fourth quarter 2015. (b) 2016 decrease driven by a decline in the dividend rate of FHN’s holdings of federal reserve bank stock. (c) 2015 driven by negative market rates on reverse repurchase agreements. (d) Calculated using total net interest income adjusted for FTE assuming a statutory federal income tax rate of 35 percent, and no where applicable, state income taxes. FHN’s net interest margin is primarily impacted by its balance sheet mix including the levels of fixed and floating rate loans, rate sensitive and non-rate sensitive liabilities, cash levels, trading inventory levels as well as loan fees and cash basis income. FHN’s balance sheet is positioned to benefit from a rise in short-term interest rates. For 2018, NIM will also depend on loan accretion levels, the extent of Fed interest rate increases, and the competitive pricing environment for core deposits. FIRST HORIZON NATIONAL CORPORATION 11 PROVISION FOR LOAN LOSSES The provision for loan losses is the charge to earnings that management determines to be necessary to maintain the ALLL at a sufficient level reflecting management’s estimate of probable incurred losses in the loan portfolio. The provision for loan losses was $0 in 2017 compared to $11.0 million in 2016 and $9.0 million in 2015. During 2017 and 2016, the continued overall improvement in the loan portfolio and declining non-strategic balances contributed to the declines of 6 percent and 4 percent in the allowance for loan losses relative to the prior years, respectively. Additionally, net charge-offs declined 35 percent and 39 percent, respectively, during 2017 and 2016 relative to the prior years. For additional information about the provision for loan losses refer to the Regional Banking and Non-Strategic sections of the Business Line Review section in this MD&A. For additional information about general asset quality trends refer to Asset Quality – Trend Analysis of 2017 Compared to 2016 in this MD&A. NONINTEREST INCOME Noninterest income (including securities gains/(losses)) was $490.2 million in 2017 compared to $552.4 million in 2016 and $517.3 million in 2015. In 2017 noninterest income was 37 percent of total revenue compared to 43 percent and 44 percent in 2016 and 2015, respectively. The decrease in noninterest income in 2017 relative to 2016 was primarily driven by a 19 percent decrease in fixed income non-interest income, as well as a $14.3 million loss from the repurchase of equity securities previously included in a financing transaction recognized in 2017. The increase in noninterest income in 2016 relative to 2015 was primarily driven by higher fixed income sales revenue. FHN’s noninterest income for the last three years is provided in Table 3 - Noninterest Income. The following discussion provides additional information about various line items reported in the following table.

Other noninterest revenues within this line item consist principally of fees from loan sales, portfolio advisory services, and derivative sales. Securities inventory positions are procured for distribution to customers by the sales staff. Fixed income noninterest income decreased 19 percent in 2017 to $216.6 million from $268.6 million in 2016, reflecting lower activity due to challenging market conditions (interest rate increases, a flattening yield curve, and low levels of market volatility). Revenue from other products increased 10 percent, or $3.8 million, to $42.7 million from $38.9 million in 2016, driven by increases in fees from loan sales, which more than offset declines in fees from derivative sales and portfolio advisory services. Fixed income noninterest income was $268.6 million in 2016, up from $231.3 million in 2015, reflecting more favorable market conditions during most of 2016, including increased rate and market volatility, as well as expansion of the distribution platform. In late 2016, trading activity was somewhat muted due to a sharp rate increase and market uncertainties following the U.S. presidential election. Revenue from other products increased $3.4 million to $38.9 million in 2016, largely driven by increases in fees from loan sales, derivative sales and portfolio advisory services. Table 4 – Fixed Income Noninterest Income Compound Annual Growth Rates (Dollars in thousands) 2017 2016 2015 17/16 17/15 Noninterest income: Fixed income Other product revenue Total fixed income noninterest income $173,910 42,715 $216,625 $229,659 38,902 $268,561 $195,877 35,460 $231,337 (24)% 10% (19)% (6)% 10% (3)% Deposit Transactions and Cash Management Fees from deposit transactions and cash management include fees for services related to consumer and commercial deposit products (such as service charges on checking accounts), cash management products and services such as electronic transaction processing (Automated Clearing House and Electronic Data Interchange), account reconciliation services, cash vault services, lockbox processing, and information reporting to large corporate clients. Deposit transactions and cash management activities increased to $110.6 million in 2017 from $108.6 million in 2016 largely driven by higher fee income associated with cash management activities, which offset a decline in NSF/overdraft fees driven by changes in consumer behavior and a modification of billing practices. In 2016, deposit transactions and cash management income decreased to $108.6 million from $112.8 million in 2015, primarily related to lower NSF fee income driven by changes in consumer behavior. Brokerage, Management Fees and Commissions Brokerage, management fees and commissions include fees for portfolio management, trade commissions, and annuity and mutual funds sales. Noninterest income from brokerage, management fees and commissions increased 13 percent, or $5.6 million, to $48.5 million in 2017. The increase was due in large part to increases in recurring revenue driven primarily by growth in FHN’s advisory business and favorable market conditions. Noninterest income from brokerage, management fees and commissions was $42.9 million and $46.5 million in 2016 and 2015, respectively. The decline in income in 2016 compared to 2015 was primarily driven by a reduction in annuity income as a result of market conditions and lower variable annuity sales as practices were adjusted to meet the standards of a changing regulatory environment. The decline was also affected by a shift in product and fee structures, which caused a temporary decline in revenues but better met client needs and should result in revenue streams over the life of the product. Bankcard Income Bankcard income is derived from fees charged for processing and supporting credit card transactions including interchange, late charges, membership fees, miscellaneous merchant fees, cash advance fees, currency conversion FIRST HORIZON NATIONAL CORPORATION 13 fees, and research fees. Bankcard income increased 4 percent to $25.5 million in 2017 from $24.4 million in 2016. The increase in bankcard income relative to the prior year was primarily due to an increase in interchange income driven by higher volume due in large part to the CBF acquisition. Bankcard income increased 10 percent in 2016 to $24.4 million from $22.2 million in 2015, primarily driven by volume incentives received in 2016 driven by a significant new relationship. Securities Gains/(Losses) In 2017 FHN recognized net securities gains of $.6 million compared to $1.3 million and $1.4 million in 2016 and 2015, respectively. The 2017 net gain was primarily the result of the call of a $4.4 million held-to-maturity municipal bond within the regional banking segment. The 2016 net gain was largely driven by a $1.5 million net gain from the exchanges of approximately $736 million of AFS debt securities, partially offset by $.2 million of other-than-temporary impairment (“OTTI”) adjustments. The 2015 net gain was largely driven by a $1.8 million gain from an exchange of approximately $335 million of AFS debt securities, partially offset by $.7 million of OTTI adjustments. Other Noninterest Income Other income includes revenues from other service charges, ATM and interchange fees, revenue related to deferred compensation plans (which are mirrored by changes in noninterest expense), electronic banking fees, letter of credit fees, mortgage banking (primarily within the non-strategic and regional banking segments), insurance commissions, gains/(losses) on the extinguishment of debt, and various other fees. Revenue from all other income and commissions was $44.9 million in 2017 compared to $64.2 million in 2016. The decrease in all other income and commissions was primarily driven by a $14.3 million loss from the repurchase of equity securities previously included in a financing transaction recognized in 2017, a $5.6 million decrease in mortgage banking income, and a $2.1 million decrease in gains on the sales of properties. The decline in mortgage banking income was due in large part to $4.4 million of recoveries recognized in 2016 associated with prior legacy mortgage servicing sales and a $1.5 million gain related to the reversal of a contingency accrual associated with prior sales of MSR, but was somewhat mitigated by a $1.7 million increase in new originations within the regional banking segment related to CRA initiatives. For 2017, all other income and commissions was favorably impacted by a $3.3 million increase in deferred compensation income, offsetting a portion of the overall decline in revenues from all other income and commissions. Deferred compensation income fluctuates with changes in the market value of the underlying investments and is mirrored by changes in deferred compensation expense which is included in personnel expense. Revenue from all other income and commissions increased to $64.2 million in 2016 from $60.7 million in 2015. For 2016 all other income and commissions was favorably impacted by increases in mortgage banking and deferred compensation income, and higher fee income associated with derivative sales. These increases were somewhat offset by a $5.8 million gain recognized in 2015 on the extinguishment of junior subordinated notes underlying $200 million of trust preferred debt and a $1.3 million decrease in 2016 in gains on the sales of properties. The increase in mortgage banking income was driven by gains recognized in 2016 related to prior legacy mortgage servicing sales and the reversal of a contingency accrual associated with prior sales of MSR previously mentioned. NONINTEREST EXPENSE Total noninterest expense increased 11 percent, or $98.5 million, to $1.0 billion in 2017 from $925.2 million in 2016. The increase in expense was primarily driven by higher acquisition- and integration-related expense associated with the CBF and Coastal acquisitions. To a lesser extent, a smaller repurchase and foreclosure provision expense reversal related to the settlement of certain repurchase claims in 2017 relative to 2016, a net increase in loss accruals related to litigation and regulatory matters, and an increase in personnel expense also contributed to the expense increase in 2017. Legal fees decreased in 2017, favorably impacting expense relative to 2016. In 2016, total noninterest expense decreased 12 percent, or $128.6 million, to $925.2 from $1.1 billion. The decrease in noninterest expense was driven by a reduction in accruals related to loss contingencies and litigation matters primarily within the non-strategic segment and, to a lesser extent, a mortgage repurchase and foreclosure provision expense reversal, somewhat offset by higher personnel expense relative to 2015. FHN’s noninterest 14 FIRST HORIZON NATIONAL CORPORATION expense for the last three years is provided in Table 5 - Noninterest Expense. The following discussion provides additional information about various line items reported in the following table.

For more detailed information about acquisition- and integration-related expenses related to the CBF acquisition refer to Note 2 – Acquisitions and Divestitures. (a) 2017 includes $8.8 million of charitable contributions to the First Tennessee Foundation. An additional contribution of 65,000 Visa Class B shares with a cost basis of $0 was also made in 2017. Employee Compensation, Incentives, and Benefits Employee compensation, incentives, and benefits (personnel expense), the largest component of noninterest expense, increased 5 percent, or $26.5 million, to $589.4 million in 2017 from $562.9 million in 2016. The increase in personnel expense was driven by several factors. Within the regional banking segment personnel expense increased due to strategic hires in expansion markets and specialty areas, higher incentive expense associated with loan/deposit growth, retention initiatives, and $19.1 million attributable to CBF activities ($10.7 million of which relates to a 27 percent increase in headcount for one month). In 2017, FHN recognized $9.9 million of special bonuses, $3.0 million related to higher deferred compensation expense, and a $2.6 million increase in pension fund expense which also contributed to the increase in personnel expense compared to 2016. Personnel expense within the fixed income segment decreased in 2017 largely driven by a decrease in variable compensation associated with lower fixed income sales revenue relative to 2016, offsetting a portion of the overall increase in personnel expense. Additionally, personnel expense was favorably impacted by $6.5 million of deferred compensation BOLI gains recognized in 2017. Personnel expense increased 10 percent, or $51.3 million, to $562.9 million in 2016 from $511.6 million in 2015. The increase in personnel expense in 2016 was driven in part by an increase in variable compensation associated FIRST HORIZON NATIONAL CORPORATION 15 with higher fixed income product sales revenue within FHN’s fixed income operating segment relative to 2015. Within the regional bank, expenses associated with strategic hires in expansion markets and specialty areas increased $9.6 million from 2015 to 2016. Additionally, higher incentive expense associated with loan growth and retention initiatives increased $4.5 million relative to 2015 and a year-over-year increase in headcount related to the TAB acquisition contributed $3.9 million to the increase in personnel expense within the regional bank in 2016. Personnel expense in 2015 was favorably impacted by an $8.3 million gain related to an amendment of certain employee benefit plans recognized in third quarter 2015, which also contributed to the increase in personnel-related expenses in 2016. Deferred compensation expense increased in 2016, relative to 2015, further contributing to the personnel expense increase in 2016. These increases were partially offset by a decline in pension expense relative to 2015 due to a change in the discount rates used in the calculation of pension and post retirement interest costs. Occupancy Occupancy expense increased to $54.6 million in 2017 from $50.9 in 2016, primarily driven by higher rental expense due to the CBF and Coastal acquisitions. Additionally, an increase in depreciation expense due to the completion of renovations to consolidated space made to the headquarters and other strategic locations during 2017 also increased occupancy relative to 2016. In 2016, occupancy expense decreased to $50.9 million from $51.1 million in 2015. The decrease in occupancy expense was the result of a decline in sublease income related to the sale of a building in 2015, somewhat offset by $.9 million of lease abandonment expense related to efficiency initiatives and higher rent expense in 2016 associated with sale-leaseback transactions recognized in 2016. Computer Software Computer software expense was $48.2 million, $45.1 million, and $44.7 million in 2017, 2016, and 2015, respectively. The increase in computer software expense is the result of FHN’s focus on technology-related projects, as well as an increase in computer software expense as a result of one month of expense related to the inclusion of Capital Bank. Professional Fees Professional fees increased $28.8 million to $47.9 million in 2017 primarily driven by acquisition- and integration- related expenses primarily associated with the CBF and Coastal acquisitions. Professional fees were $19.2 million and $18.9 million in 2016 and 2015, respectively. Operations Services Operations services expense increased 5 percent, or $2.0 million to $43.8 million in 2017, primarily related to an increase in thirty party fees associated with the CBF and Coastal acquisitions. In 2016, expenses from operations services were $41.9 million compared to $39.3 million in 2015, primarily related to an increase in third party fees associated with FHN’s online digital banking platform. FDIC Premium Expense FDIC premium expense was $26.8 million in 2017, compared to $21.6 million and $18.0 million in 2016 and 2015, respectively. The increase in FDIC premium expense was due in large part to balance sheet growth, both organically and with the CBF and Coastal acquisitions for 2017. Additionally, the net loss recognized in fourth quarter 2017 also contributed to the increase in FDIC premium expense. Advertising and Public Relations Expenses associated with advertising and public relations decreased to $19.2 million in 2017 compared in $21.6 million and $19.2 million in 2016 and 2015, respectively. In 2016, FHN recognized higher advertising and public relations expense due in large part to a promotional branding campaign and higher expenses associated with CRA initiatives. 16 FIRST HORIZON NATIONAL CORPORATION Contract Employment and Outsourcing Expenses associated with contract employment and outsourcing increased 49 percent, or $4.9 million, to $15.0 million in 2017, primarily driven by acquisition- and integration-related projects primarily associated with the CBF acquisition and an increase in technology-related projects as compared to 2016. Expenses associated with contract employment and outsourcing decreased 31 percent, or $4.4 million, to $10.1 million in 2016. The decrease was attributable to a lower number of technology-related projects in 2016 relative to 2015 coupled with the completion of a large operations efficiency project in 2015. Legal Fees Legal fees were $12.1 million, $21.6 million, and $16.3 million in 2017, 2016, and 2015, respectively. Legal fees fluctuate primarily based on the status, timing, type, and composition of cases or other projects. Amortization of Intangibles Amortization expense was $8.7 million in 2017, up from $5.2 million in 2016 and $5.3 million in 2015. The increase was due to amortization expense as a result of the CBF and Coastal acquisitions. Repurchase and Foreclosure Provision During 2017 and 2016, FHN recognized a $22.5 million and a $32.7 million pre-tax expense reversal of mortgage repurchase and foreclosure provision primarily as a result of the settlement/recoveries of certain repurchase claims. The mortgage repurchase and foreclosure provision expense was $0 in 2015. Other Noninterest Expense Other expense includes losses from litigation and regulatory matters, travel and entertainment expense, other insurance and tax expense, customer relations expense, costs associated with employee training and dues, supplies, tax credit investments expenses, miscellaneous loan costs, expenses associated with OREO, and various other expenses. All other expense increased 15 percent, or $16.9 million, to $133.2 million in 2017 from $116.3 million in 2016. The increase was primarily driven by a $10.0 million increase in pre-tax loss accruals related to legal matters and $8.8 million of charitable contributions to the First Tennessee Foundation. Additionally, FHN recognized $9.0 million in acquisition-and integration-related costs in 2017 and a $2.0 million vendor payment adjustment which also contributed to the expense increase in 2017. Offsetting a portion of the expense increase, FHN experienced a $2.0 million decrease in negative valuation adjustments associated with derivatives related to prior sales of Visa Class B shares, as well as a $1.2 million decrease in other insurance and taxes driven by favorable adjustments to franchise taxes related to community reinvestment efforts. All other expense decreased 57 percent to $116.3 million in 2016 from $268.2 million in 2015. The decrease in expense between 2016 and 2015 was primarily driven by a $157.1 million net decline in accruals related to loss contingencies and legal matters, from $187.6 million in 2015 to $30.5 million in 2016. The decrease in accruals related to loss contingencies and legal matters was largely associated with the 2015 DOJ/HUD settlement of potential claims related to FHN’s underwriting and origination of FHA-insured mortgage loans within the non- strategic segment. To a much smaller extent, a decline in other insurance and taxes in 2016 associated with favorable adjustments to franchise taxes related to community reinvestment efforts, and a $1.2 million decrease in tax credit investments due in large part to a $2.8 million impairment recognized in 2015 also contributed to the 2016 expense decline. FHN recognized a $3.9 million net increase in fixed asset impairments and lease abandonment charges related to branch closures in 2016 relative to 2015, offsetting a portion of the expense decline. Additionally, a $1.9 million net increase in negative valuation adjustments associated with derivatives related to prior sales of Visa Class B shares resulted in higher expenses in 2016. FIRST HORIZON NATIONAL CORPORATION 17 INCOME TAXES FHN recorded an income tax provision of $131.9 million in 2017, compared to $106.8 million in 2016 and $10.9 million in 2015. FHN’s effective tax rates for 2017, 2016, 2015 were approximately 42.7 percent, 30.9 percent and 10.1 percent, respectively. The increase in the effective tax rates in 2017 compared to 2016 and 2015 was primarily driven by $82 million of tax expense related to the effects of federal tax reform, this was partially offset by the reversal of a capital loss valuation allowance which lowered taxes by $40.4 million. The reversal of the capital loss valuation allowance was attributable to the utilization of the carryforward against capital gains realized in 2017. On December 22, 2017, the Tax Cuts and Jobs Act “Tax Act” was signed into law. The Tax Act reduces the federal statutory tax rate from 35 percent to 21 percent. Although the rate reduction was not effective until January 1, 2018, ASC Topic 740 requires an adjustment in 2017 of deferred tax balances to reflect the new effective tax rate. The $82 million increase in tax expense related to the Tax Act is primarily based on the decrease in FHN’s net deferred tax balance resulting from a decrease in the federal tax rate. This amount will be adjusted during the measurement period related to the CBF acquisition and as deferred tax items are finalized for the 2017 return. Although the initial effect of the Tax Act resulted in a tax increase during 2017, the changes under the Tax Act will favorably impact First Horizon’s financial results and operations in future years due to the reduced federal statutory rate. The company’s effective tax rate is favorably affected by recurring items such as bank-owned life insurance, tax- exempt income, and credits and other tax benefits from affordable housing investments. The company’s effective tax rate also may be affected by items that may occur in any given period but are not consistent from period to period, such as changes in the deferred tax asset valuation allowance and changes in unrecognized tax benefits. A deferred tax asset (“DTA”) or deferred tax liability (“DTL”) is recognized for the tax consequences of temporary differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. The tax consequence is calculated by applying enacted statutory tax rates, applicable to future years, to these temporary differences. As of December 31, 2017, FHN’s net DTA was $221.8 million compared with $199.6 million at December 31, 2016 and $259.3 million at December 31, 2015. FHN’s gross DTA (net of a valuation allowance) and gross DTL were $353.2 million and $131.4 million, respectively. FHN’s net DTA increased by $137.7 million on November 30, 2017 upon the merger of CBF into FHN. The $82 million adjustment related to the Tax Act, discussed above, includes tax expense related to a decrease in the acquired net DTA from CBF by approximately $48 million due to the adjustment of the DTA to the lower federal tax rate. As of December 31, 2017, FHN had deferred tax asset balances related to federal and state income tax carryforwards of $126.8 million and $19.8 million, which will expire at various dates. As of December 31, 2017, FHN had fully utilized all federal capital loss carryovers. As of December 31, 2016, FHN had a valuation allowance of $40.4 million against its federal capital loss carryforwards. FHN’s gross DTA after valuation allowance was $353.2 million and $297.0 million as of December 31, 2017 and 2016, respectively. Based on current analysis, FHN believes that its ability to realize the remaining DTA is more likely than not. FHN monitors its DTA and the need for a valuation allowance on a quarterly basis. A significant adverse change in FHN’s taxable earnings outlook could result in the need for a valuation allowance. FHN and its eligible subsidiaries are included in a consolidated federal income tax return. FHN files separate returns for subsidiaries that are not eligible to be included in a consolidated federal income tax return. Based on the laws of the applicable states where it conducts business operations, FHN either files consolidated, combined, or separate returns. The federal tax returns for Capital Bank Financial Corporation for 2010 - 2012 are under examination by the IRS. With few exceptions, FHN returns are no longer subject to federal or state and local tax examinations by tax authorities for years before 2013. FHN is currently under federal examination for 2013 - 2015 and is also under examination in several states. See also Note 15 – Income Taxes for additional information. 18 FIRST HORIZON NATIONAL CORPORATION STATEMENT OF CONDITION REVIEW – 2017 COMPARED TO 2016 Total period-end assets were $41.4 billion on December 31, 2017, up 45 percent from $28.6 billion on December 31, 2016. Average assets increased to $29.9 billion in 2017 from $27.4 billion in 2016. The increase in average assets compared to 2016 is primarily attributable to net increases in the loan portfolios, loans held-for-sale (“HFS”), and interest bearing cash, as well as, goodwill and other intangible assets added during 2017 as a result of the CBF and Coastal acquisitions. On a period-end basis, the increase was primarily due to the CBF acquisition which resulted in net increases in the loan portfolios, a larger investment securities portfolio, and increases to goodwill and other intangible assets. Increases in loans HFS and fixed income inventory also contributed to the increase in period-end assets on December 31, 2017, as did nearly all line items on the balance sheet due to the acquisition of CBF. Total period-end liabilities were $36.8 billion on December 31, 2017, a 43 percent increase from $25.9 billion on December 31, 2016. Average liabilities increased to $27.0 billion in 2017, from $24.7 billion in 2016. The increase in period end and average liabilities was primarily the result of the CBF and Coastal acquisitions. The increase in average liabilities was due to an increase in deposits, and to a lesser extent an increase in other short-term borrowings. Lower average balances of federal funds purchased and trading liabilities during 2017 compared to the prior year offset a portion of the overall increase in liabilities. Higher deposit balances and an increase in other short-term borrowings (primarily FHLB borrowings) at December 31, 2017 were the primary drivers of the increase in liabilities on a period-end basis. EARNING ASSETS Earning assets consist of loans, investment securities, other earning assets such as trading securities, interest- bearing cash, and loans HFS. Average earning assets increased to $27.5 billion in 2017 from $25.2 billion in 2016. A more detailed discussion of the major line items follows. Loans Period-end loans increased 41 percent to $27.7 billion as of December 31, 2017 from $19.6 billion on December 31, 2016. Average loans for 2017 were $20.1 billion compared to $18.3 billion for 2016. The increase in average loan balances was primarily due to organic growth in several of the commercial loan portfolios within FHN’s regional banking segment excluding the CBF merger, coupled with commercial and consumer loans added through the CBF acquisition in fourth quarter 2017. Continued run-off of consumer loans portfolios within the non- strategic segment negatively impacted loan balances on an average basis in 2017, somewhat offsetting a portion of the overall increase in average loan balances. Additionally, lower average balances of loans to mortgage companies also offset a portion of the increase in average loans. The increase in period-end loans was primarily the result of the addition of $7.3 billion in loans from the CBF acquisition and organic growth within FHN’s ex-CBF regional banking segment, somewhat offset by run-off within the non-strategic portfolios.

C&I loans are the largest component of the commercial portfolio, comprising 84 percent of average commercial loans in both 2017 and 2016. Average C&I loans increased 13 percent, or $1.4 billion, from 2016 due to net loan growth within several of the regional bank’s portfolios including franchise finance, commercial, and international, somewhat offset by lower balances of loans to mortgage companies. Average commercial real estate loans increased 22 percent to $2.4 billion in 2017 because of growth in expansion markets and increased funding under existing commitments. In addition, the fourth quarter 2017 CBF acquisition also contributed to the increase. Average consumer loans declined 1 percent from a year ago to $5.4 billion in 2017. The consumer real estate portfolio (home equity lines and installment loans) declined $46.4 million to $4.6 billion, as the continued wind- down of portfolios within the non-strategic segment outpaced a $353.9 million increase in real estate installment loans within the regional banking segment primarily from new originations combined with the impact of the CBF acquisition. The permanent mortgage portfolio declined $30.0 million to $407.6 million in 2017 driven by run-off of legacy assets within the non-strategic segment offset by some growth in mortgage loans within regional banking, primarily related to FHN’s CRA initiatives. Credit Card and Other increased $15.0 million to $374.4 million. The following table provides a detail of contractual maturities of commercial loans on December 31, 2017.

A significant component of FHN’s loan portfolio consists of consumer real estate loans – a majority of which are home equity lines of credit and home equity installment loans. Typical home equity lines originated by FHN are variable rate 5/15, 10/10, or 10/20 lines. In a 5/15 line, a borrower may draw on the loan for 5 years and pay interest only during that period (“the draw period”), and for the next 15 years the customer pays principal and interest and may no longer draw on that line. A 10/10 loan has a 10 year draw period followed by a 10-year principal-and-interest repayment period, and a 10/20 loan has a 10 year draw period followed by a 20-year principal-and-interest repayment period. Therefore, the contractual maturity for 5/15 and 10/10 home equity lines is 20 years and the contractual maturity for 10/20 home equity lines is 30 years. Numerous factors can contribute to the actual life of a home equity line or installment loan. In normalized market conditions, the average life of home equity line and installment loan portfolios is significantly less than the contractual period as indicated by historical trends. More recent indicators suggest that the average life of these portfolios could be longer when compared to that observed in normalized market conditions. This could be attributed to the reduced availability of new credit in the marketplace, weak performance of the housing market for much of the past ten years, and a historically low interest rate environment which is likely to have slowed prepayment rates. However, the actual average life of home equity lines and loans is difficult to predict and changes in any of these factors could result in changes in projections of average lives. Investment Securities FHN’s investment portfolio consists principally of debt securities including government agency issued mortgage- backed securities (“MBS”) and government agency issued collateralized mortgage obligations (“CMO”), substantially all of which are classified as AFS. FHN utilizes the securities portfolio as a source of income, liquidity and collateral for repurchase agreements, for public funds, and as a tool for managing risk of interest rate movements. Table 8 – Contractual Maturities of Investment Securities on December 31, 2017 (Amortized Cost) shows information pertaining to the composition, yields, and contractual maturities of the investment portfolio. Investment securities increased to $5.2 billion on December 31, 2017 from $4.0 billion on December 31, 2016 primarily due to the acquisition of CBF. Average investment securities were $4.0 billion in 2017 and 2016, representing 15 percent and 16 percent of average earning assets in 2017 and 2016, respectively. FHN manages the size and mix of the investment portfolio to assist in asset liability management, provide liquidity, and optimize risk adjusted returns. Government agency issued MBS, CMO, and other agencies averaged $3.8 billion in 2017 and 2016. U.S. treasury securities and corporate and municipal bonds averaged $16.2 million in 2017 compared to $15.2 million in 2016. Investments in equity securities averaged $190.3 million in 2016 compared with $186.4 million in 2016. A majority of the equity security balances include restricted investments in the Federal Home Loan Bank (“FHLB”) and Federal Reserve Bank (“FRB”) which averaged $151.4 million and $156.0 million in 2017 and 2016, respectively. On December 31, 2017, AFS investment securities had $35.7 million of net unrealized losses compared to $27.9 million of net unrealized losses on December 31, 2016.

Loans Held-for-Sale Loans HFS consists of small business, other consumer loans, the mortgage warehouse, USDA, student, and home equity loans. On December 31, 2017 loans HFS were $699.4 million compared to $111.2 million on December 31, 2016. The average balance of loans HFS increased to $370.6 million from $124.3 million in 2016. The increase in period-end and average loans HFS was primarily driven by the Coastal acquisition in second quarter 2017, which resulted in an increase in small business loans and the addition of USDA loans, as well as the addition of other consumer loans acquired as part of the CBF acquisition in fourth quarter 2017. Other Earning Assets Other earning assets include trading securities, securities purchased under agreements to resell (“asset repos”), federal funds sold (“FFS”), and interest-bearing deposits with the Fed and other financial institutions. Other earning assets averaged $3.0 billion in 2017, up from $2.7 billion in 2016. The increase in other earning assets was primarily driven by higher levels of interest-bearing cash primarily driven by higher average balances of customer deposits. A decrease in average asset repos and fixed income trading securities in 2017 compared with 2016 offset a portion of the overall increase in other earning assets. Asset repos are used in fixed income trading activity and generally fluctuate with the level of fixed income trading liabilities (short-positions) as securities collateral from asset repo transactions are used to fulfill trades. Fixed income’s trading inventory fluctuates daily based on customer demand. Other earning assets were $3.4 billion and $2.6 billion on December 31, 2017 and 2016, respectively. The increase in other earning assets on a period-end basis was primarily driven by an increase in fixed income trading securities, as well as increases in interest-bearing cash and asset repos. Non-earning assets Period-end non-earning assets increased to $4.5 billion on December 31, 2017 from $2.3 billion on December 31, 2016. The increase in non-earning assets was primarily due to increases in goodwill, premises and equipment, and intangible assets associated with the CBF and Coastal acquisitions. Other assets also increased from December 31, 2016 to December 31, 2017 largely driven by increases in deferred tax assets associated with the CBF acquisition, and BOLI assets acquired in the CBF acquisition. Deposits Average deposits were $23.1 billion during 2017, up 10 percent from $20.9 billion during 2016. As noted in the table below, the composition of deposits remained consistent in 2017 with interest-bearing deposits comprising 72 percent of total deposits. As a percentage of total deposits, market-indexed deposits decreased 1 percent and commercial interest deposits increased 1 percent compared with 2016. Period-end deposits were $30.6 billion on December 31, 2017, up 35 percent from $22.7 billion on December 31, 2016. The increase in period-end and 22 FIRST HORIZON NATIONAL CORPORATION average deposits was due primarily to the addition of $8.1 billion of deposits associated with the CBF acquisition; however, due to the late-year timing of the acquisition, the impact was much less on an average basis.

Short-Term Borrowing Short-term borrowings (federal funds purchased (“FFP”), securities sold under agreements to repurchase, trading liabilities, and other short-term borrowings) averaged $2.3 billion in 2017 and $2.0 billion in 2016. As noted in the table below other short-term borrowings and securities sold under agreements to repurchase increased during 2017, while trading liabilities and FFP decreased during 2017 compared to the prior year. Other short-term borrowings balances fluctuate largely based on the level of FHLB borrowing as a result of loan demand, deposit levels and balance sheet funding strategies. Securities sold under agreements to repurchase increased primarily as a result of the Coastal and CBF acquisitions. Average FFP fluctuates depending on the amount of excess funding of FHN’s correspondent bank customers and average trading liabilities fluctuates based on expectations of customer demand. Period-end short-term borrowings were $4.3 billion on December 31, 2017 and $1.5 billion in 2016. The increase in period-end short-term borrowings was primarily due to an increase in FHLB borrowings.

Term borrowings were $1.2 billion on December 31, 2017 compared to $1.0 billion on December 31, 2016, primarily due to the addition of junior subordinated debentures underlying $206 million of trust preferred debt acquired in association with the CBF acquisition. Average term borrowings were $1.1 billion in 2017 and 2016. See Note 10 – Term Borrowings for additional information. FIRST HORIZON NATIONAL CORPORATION 23 Other Liabilities Period-end other liabilities increased to $.7 billion on December 31, 2017 from $.6 billion on December 31, 2016. CAPITAL – 2017 COMPARED TO 2016 Management’s objectives are to provide capital sufficient to cover the risks inherent in FHN’s businesses, to maintain excess capital to well-capitalized standards, and to assure ready access to the capital markets. Period-end equity increased to $4.6 billion on December 31, 2017 from $2.7 billion on December 31, 2016 due in large part to $1.8 billion of equity issued in connection with the CBF acquisition on November 30, 2017. Average equity increased to $3.0 billion in 2017 from $2.7 billion in 2016. The increase in average equity was due to net income recognized since 2016, partially offset by common and preferred dividends paid, and the average impact of the equity issued in association with the CBF acquisition previously mentioned. Average equity was negatively impacted by a decline in accumulated other comprehensive income in 2017, offsetting a portion of the increase in average equity. The decline in average accumulated other comprehensive income was largely the result of unrealized losses recognized on the AFS securities portfolio, as well as an increase of net actuarial losses for pension and post retirement plans and results of cash flow hedges. As previously mentioned, effective February 14, 2018 FHN elected early adoption of ASU 2018-02, “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income,” which resulted in a reclassification of $57.5 million out of period-end AOCI into retained earnings. This reclassification is reflected in FHN’s and FTBNA’s regulatory capital balances and ratios as of December 31, 2017. The following tables provide a reconciliation of Shareholders’ equity from the Consolidated Statements of Condition to Common Equity Tier 1, Tier 1 and Total Regulatory Capital as well as certain selected capital ratios: Table 11 – Regulatory Capital and Ratios (Dollars in thousands) Shareholders’ equity FHN non-cumulative perpetual preferred Common equity Regulatory adjustments: Disallowed goodwill and other intangibles Net unrealized (gains)/losses on securities available-for-sale Net unrealized (gains)/losses on pension and other postretirement plans Net unrealized (gains)/losses on cash flow hedges Disallowed deferred tax assets Other deductions from common equity tier 1 Common equity tier 1 FHN non-cumulative perpetual preferred Qualifying noncontrolling interest – FTBNA preferred stock Other deductions from tier 1 Tier 1 capital Tier 2 capital Total regulatory capital Risk-Weighted Assets First Horizon National Corporation First Tennessee Bank National Association Average Assets for Leverage First Horizon National Corporation First Tennessee Bank National Association December 31, 2017 December 31, 2016 $ 4,285,057 (95,624) $ 2,409,653 (95,624) $ 4,189,433 $ 2,314,029 (1,480,725) 26,834 288,227 7,764 (69,065) (313) $ 2,962,155 95,624 257,080 (33,381) $ 3,281,478 422,276 $ 3,703,754 (165,292) 17,232 229,157 1,265 (18,027) (377) $ 2,377,987 95,624 256,811 (58,551) $ 2,671,871 254,139 $ 2,926,010 $33,373,877 32,786,547 $23,914,158 23,447,251 31,824,751 31,016,187 28,581,251 27,710,158 24 FIRST HORIZON NATIONAL CORPORATION Common Equity Tier 1 First Horizon National Corporation First Tennessee Bank National Association Tier 1 First Horizon National Corporation First Tennessee Bank National Association Total First Horizon National Corporation First Tennessee Bank National Association Tier 1 Leverage First Horizon National Corporation First Tennessee Bank National Association Other Capital Ratios Total period-end equity to tangible assets Tangible common equity to tangible assets (a) Adjusted tangible common equity to risk weighted assets (a) December 31, 2017 December 31, 2016 Ratio Amount Ratio Amount 8.88% $2,962,155 3,041,420 9.28 9.94% $2,377,987 2,298,080 9.80 9.83 10.12 11.10 10.74 10.31 10.70 11.06 6.57 7.91 3,281,478 3,317,684 11.17 10.83 2,671,871 2,538,382 3,703,754 3,520,670 12.24 11.78 2,926,010 2,762,271 2,671,871 2,538,382 3,281,478 3,317,684 9.35 9.16 9.47 7.42 8.86 (a) Tangible common equity to tangible assets and Adjusted tangible common equity to risk-weighted assets are non-GAAP measures and are reconciled to Total equity to total assets (GAAP) in the Non-GAAP to GAAP Reconciliation – Table 33. Banking regulators define minimum capital ratios for bank holding companies and their bank subsidiaries. Based on the capital rules and definitions prescribed by the banking regulators, should any depository institution’s capital ratios decline below predetermined levels, it would become subject to a series of increasingly restrictive regulatory actions. The system categorizes a depository institution’s capital position into one of five categories ranging from well-capitalized to critically under-capitalized. For an institution the size of FHN to qualify as well-capitalized, Common Equity Tier 1, Tier 1 Capital, Total Capital, and Leverage capital ratios must be at least 6.5 percent, 8 percent, 10 percent, and 5 percent, respectively. As of December 31, 2017, each of FHN and FTBNA had sufficient capital to qualify as a well-capitalized institution. For both FHN and FTBNA, regulatory capital ratios declined in 2017 relative to 2016 primarily due to the impact of increased disallowed intangible assets related to the CBF and Coastal acquisitions and increased risk-weighted assets primarily as a result of the increase in period end loans from the CBF acquisition. During 2018, capital ratios are expected to remain above well-capitalized standards. In March 2014, the OCC, Federal Reserve, and FDIC issued final supervisory guidance for stress tests pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (“Reform Act”). Under these requirements, bank holding companies with $10 billion to $50 billion in assets must conduct an annual stress test to determine whether capital is likely to be adequate to absorb losses under hypothetical economic scenarios provided by the regulators. In July 2017, FHN submitted results of its annual Dodd-Frank Act Stress Test, commonly known as DFAST, to the OCC and the Federal Reserve. A summary of the results was posted in October 2017 to FHN’s investor relations website. (Neither FHN’s stress test posting, nor any other material found on FHN’s website generally, is part of this report or incorporated herein.) Common Stock Purchase Programs Pursuant to board authority, FHN may repurchase shares of its common stock from time to time and will evaluate the level of capital and take action designed to generate or use capital, as appropriate, for the interests of the shareholders, subject to legal and regulatory restrictions. Two common stock purchase programs currently authorized are discussed below. FHN’s board has not authorized a preferred stock purchase program. FIRST HORIZON NATIONAL CORPORATION 25 Table 12 – Issuer Purchases of Common Stock General Program. On January 22, 2014, FHN announced a $100 million share purchase authority with an expiration date of January 31, 2016. On July 21, 2015, FHN announced a $100 million increase in that authority along with an extension of the expiration date to January 31, 2017, and on April 26, 2016, FHN announced a $150 million increase and further extension to January 31, 2018. As of December 31, 2017, the program authorized total purchases of up to $350 million and expired on January 31, 2018. As of December 31, 2017, $160.3 million in purchases had been made under this authority at an average price per share of $12.86, $12.84 excluding commissions. During 2017, FHN did not repurchase any common shares under the program. In 2016 FHN repurchased $93.5 million of common shares under the program. In January 2018, FHN’s board of directors approved a new $250 million common share purchase program that will expire on January 31, 2020. The new program is not tied to any compensation plan, and replaces the general share purchase program previously mentioned, which was terminated by the board. Purchases may be made in the open market or through privately negotiated transactions and are subject to market conditions, accumulation of excess equity, prudent capital management, and legal and regulatory restrictions.

In January 2018, the current plan was terminated and FHN’s board of directors approved a new $250.0 million common share repurchase program. Compensation Plan Program. A consolidated compensation plan share purchase program was announced on August 6, 2004. This program consolidated into a single share purchase program all of the previously authorized compensation plan share programs as well as the renewal of the authorization to purchase shares for use in connection with two compensation plans for which the share purchase authority had expired. The total amount authorized under this consolidated compensation plan share purchase program, inclusive of a program amendment on April 24, 2006, is 29.6 million shares calculated before adjusting for stock dividends distributed through January 1, 2011. The authorization has been reduced for that portion which relates to compensation plans for which no options remain outstanding. The shares may be purchased over the option exercise period of the various compensation plans on or before December 31, 2023. On December 31, 2017, the maximum number of shares that may be purchased under the program was 25.4 million shares. Purchases may be made in the open market or through privately negotiated transactions and are subject to market conditions, accumulation of excess equity, prudent capital management, and legal and regulatory restrictions. Management currently does not anticipate purchasing a material number of shares under this authority during 2018. 26 FIRST HORIZON NATIONAL CORPORATION Compensation Plan-Related Repurchase Authority: (Volume in thousands, except per share data) 2017 October 1 to October 31 November 1 to November 30 December 1 to December 31 Total Total number of shares purchased Average price paid per share Total number of shares purchased as part of publicly announced programs Maximum number of shares that may yet be purchased under the programs 12 1 1 14 $19.02 $18.63 $20.09 $19.10 12 1 1 14 25,446 25,446 25,444 ASSET QUALITY – TREND ANALYSIS OF 2017 COMPARED TO 2016 Loan Portfolio Composition FHN groups its loans into portfolio segments based on internal classifications reflecting the manner in which the ALLL is established and how credit risk is measured, monitored, and reported. From time to time, and if conditions are such that certain subsegments are uniquely affected by economic or market conditions or are experiencing greater deterioration than other components of the loan portfolio, management may determine the ALLL at a more granular level. Commercial loans are composed of commercial, financial, and industrial (“C&I”) and commercial real estate (“CRE”). Consumer loans are composed of consumer real estate; permanent mortgage; and credit card and other. FHN has a concentration of residential real estate loans (24 percent of total loans), the majority of which is in the consumer real estate portfolio (23 percent of total loans). Industry concentrations are discussed under the heading C&I below. Acquired Loans On November 30, 2017, FHN completed its acquisition of CBF. The acquisition included $7.6 billion in unpaid principal balance of loans with an estimated fair value of $7.4 billion. Acquired loans were initially recorded at fair value which was estimated by discounting expected cash flows at the acquisition date. The expected cash flows include all contractually expected amounts and incorporate an estimate for future expected credit losses, pre- payment assumptions and yield requirement for a market participant, among other things. Because an expectation of credit losses is embedded in the fair value estimate, there is no carryover of allowance for loan losses. See Note 4 - Loans for additional information regarding the acquisition. Certain loans acquired were designated as purchased credit-impaired (“PCI”) loans. PCI loans are loans that have exhibited deterioration of credit quality between origination and the time of acquisition and for which the timely collection of the interest and principal is no longer reasonably assured. FHN considered several factors when determining whether a loan met the definition of a PCI loan at the time of acquisition including accrual status, loan grade, delinquency trends, pre-acquisition charge-offs, as well as both originated versus refreshed credit scores and ratios when available. On December 31, 2017, the unpaid principal balance and the carrying value of PCI loans (inclusive of the CBF acquisition and prior franchise finance loan purchase and two previous bank acquisitions) were $199.7 million and $176.4 million, respectively. Underwriting Policies and Procedures The following sections describe each portfolio as well as general underwriting procedures for each. As economic and real estate conditions develop, enhancements to underwriting and credit policies and procedures may be necessary or desirable. Loan policies and procedures for all portfolios are reviewed by credit risk working groups and management risk committees comprised of business line managers and credit administration professionals as well as by various other reviewing bodies within FHN. Policies and procedures are approved by key executive and/or senior managers leading the applicable credit risk working groups as well as by management risk committees. The credit risk working groups and management risk committees strive to ensure that the approved FIRST HORIZON NATIONAL CORPORATION 27 policies and procedures address the associated risks and establish reasonable underwriting criteria that appropriately mitigate risk. Policies and procedures are reviewed, revised and re-issued periodically at established review dates or earlier if changes in the economic environment, portfolio performance, the size of portfolio or industry concentrations, or regulatory guidance warrant an earlier review. In 2017, we expanded our borrower limits in association with the expansion of our overall portfolio through the acquisition of CBF. Additionally, we also revised our Portfolio Concentration, Country Exposure, and Automated Clearing House limits to more appropriately align with our overall risk appetite and to provide more granularity into some of our portfolio sub segments. These changes were approved by management risk committees and the Executive and Risk Committee of the Board in order to enhance and support loan growth while also minimizing incremental credit risk. COMMERCIAL LOAN PORTFOLIOS FHN’s commercial loan approval process grants lending authority based upon job description, experience, and performance. The lending authority is delegated to the business line (Market Managers, Departmental Managers, Regional Presidents, Relationship Managers (“RM”) and Portfolio Managers (“PM”)) and to Credit Risk Managers. While individual limits vary, the predominant amount of approval authority is vested with the Credit Risk Management function. Portfolio, industry, and borrower concentration limits for the various portfolios are established by executive management and approved by the Executive and Risk Committee of the Board. FHN’s commercial lending process incorporates a RM and PM for most commercial credits. The PM is responsible for assessing the credit quality of the borrower, beginning with the initial underwriting and continuing through the servicing period, while the RM is primarily responsible for communications with the customer and maintaining the relationship. Other specialists and the assigned RM/PM are organized into units called deal teams. Deal teams are constructed with specific job attributes that facilitate FHN’s ability to identify, mitigate, document, and manage ongoing risk. PMs and credit analysts provide enhanced analytical support during loan origination and servicing, including monitoring of the financial condition of the borrower and tracking compliance with loan agreements. Loan closing officers and the construction loan management unit specialize in loan documentation and the management of the construction lending process. FHN strives to identify problem assets early through comprehensive policies and guidelines, targeted portfolio reviews, and an emphasis on frequent grading. For smaller commercial credits, generally $3 million or less, FHN utilizes a centralized underwriting unit in order to originate and grade small business loans more efficiently and consistently. FHN may utilize availability of guarantors/sponsors to support commercial lending decisions during the credit underwriting process and when determining the assignment of internal loan grades. Reliance on the guaranty as a viable secondary source of repayment is a function of an analysis proving capability to pay, factoring in, among other things, liquidity and direct/indirect cash flows. FHN also considers the volume and amount of guaranties provided for all global indebtedness and the likelihood of realization. FHN presumes a guarantor’s willingness to perform until there is any current or prior indication or future expectation that the guarantor may not willingly and voluntarily perform under the terms of the guaranty. In FHN’s risk grading approach, it is deemed that financial support becomes necessary generally at a point when the loan would otherwise be graded substandard, reflecting a well-defined weakness. At that point, provided willingness and capacity to support are appropriately demonstrated, a strong, legally enforceable guaranty can mitigate the risk of default or loss, justify a less severe rating, and consequently reduce the level of allowance or charge-off that might otherwise be deemed appropriate. C&I The C&I portfolio was $16.1 billion on December 31, 2017, and is comprised of loans used for general business purposes. Typical products include working capital lines of credit, term loan financing of owner-occupied real estate and fixed assets, and trade credit enhancement through letters of credit. The largest geographical concentrations of balances as of December 31, 2017, are in Tennessee (36 percent), North Carolina (13 percent), Florida (6 percent), California (6 percent), Texas (5 percent), Georgia (4 percent), and South Carolina (4 percent), with no other state representing more than 3 percent of the portfolio. C&I loans are underwritten in accordance with a well-defined credit origination process. This process includes applying minimum underwriting standards as well as separation of origination and credit approval roles on 28 FIRST HORIZON NATIONAL CORPORATION transaction sizes over PM authorization limits. Underwriting typically includes due diligence of the borrower and the applicable industry of the borrower, analysis of the borrower’s available financial information, identification and analysis of the various sources of repayment and identification of the primary risk attributes. Stress testing the borrower’s financial capacity, adherence to loan documentation requirements, and assigning credit risk grades using internally developed scorecards are also used to help quantify the risk when appropriate. Underwriting parameters also include loan-to-value ratios (“LTVs”) which vary depending on collateral type, use of guaranties, loan agreement requirements, and other recommended terms such as equity requirements, amortization, and maturity. Approval decisions also consider various financial ratios and performance measures of the borrowers, such as cash flow and balance sheet leverage, liquidity, coverage of fixed charges, and working capital. Additionally, approval decisions consider the capital structure of the borrower, sponsorship, and quality/value of collateral. Generally, guideline and policy exceptions are identified and mitigated during the approval process. Pricing of C&I loans is based upon the determined credit risk specific to the individual borrower. These loans typically have variable rates tied to the London Inter-Bank Offered Rate (“LIBOR”) or the prime rate of interest plus or minus the appropriate margin. The following table provides the composition of the C&I portfolio by industry as of December 31, 2017 and 2016. For purposes of this disclosure, industries are determined based on the North American Industry Classification System (“NAICS”) industry codes used by Federal statistical agencies in classifying business establishments for the collection, analysis, and publication of statistical data related to the U.S. business economy.

(b) Industries in this category each comprise less than 5 percent for 2017. Industry Concentrations Loan concentrations are considered to exist for a financial institution when there are loans to numerous borrowers engaged in similar activities that would cause them to be similarly impacted by economic or other conditions. 31 percent of FHN’s C&I portfolio (Finance and insurance plus Loans to mortgage companies) could be affected by items that uniquely impact the financial services industry. Except “Finance and Insurance” and “Loans to Mortgage Companies”, as discussed below, on December 31, 2017, FHN did not have any other concentrations of C&I loans in any single industry of 10 percent or more of total loans. Finance and Insurance The finance and insurance component represents 18 percent of the C&I portfolio and includes TRUPS (i.e., long- term unsecured loans to bank and insurance-related businesses), loans to bank holding companies, and asset- based lending to consumer finance companies. As of December 31, 2017, asset-based lending to consumer finance companies represents approximately $1.2 billion of the finance and insurance component. FIRST HORIZON NATIONAL CORPORATION 29 TRUPS lending was originally extended as a form of “bridge” financing to participants in the pooled trust preferred securitization program offered primarily to smaller banking (generally less than $15 billion in total assets) and insurance institutions through FHN’s fixed income business. Origination of TRUPS lending ceased in early 2008. Individual TRUPS are re-graded at least quarterly as part of FHN’s commercial loan review process. The terms of these loans generally include a scheduled 30 year balloon payoff and include an option to defer interest for up to 20 consecutive quarters. As of December 31, 2017, and December 31, 2016, one TRUP relationship was on interest deferral. As of December 31, 2017, the unpaid principal balance (“UPB”) of trust preferred loans totaled $332.5 million ($206.2 million of bank TRUPS and $126.3 million of insurance TRUPS) with the UPB of other bank-related loans totaling $262.4 million. Inclusive of a valuation allowance on TRUPS of $25.5 million, total reserves (ALLL plus the valuation allowance) for TRUPS and other bank-related loans were $26.8 million or 5 percent of outstanding UPB. Loans to Mortgage Companies The balance of loans to mortgage companies was 13 percent of the C&I portfolio as of December 31, 2017, and 17 percent of the C&I portfolio as of December 31, 2016, and includes balances related to both home purchase and refinance activity. This portfolio class, which generally fluctuates with mortgage rates and seasonal factors, includes commercial lines of credit to qualified mortgage companies primarily for the temporary warehousing of eligible mortgage loans prior to the borrower’s sale of those mortgage loans to third party investors. Generally, lending to mortgage lenders increases when there is a decline in mortgage rates and decreases when rates rise. C&I Asset Quality Trends Overall, the C&I portfolio trends remain strong in 2017, continuing in line with recent historical performance. The C&I ALLL increased $8.8 million from December 31, 2016, to $98.2 million as of December 31, 2017. The allowance as a percentage of period-end loans decreased to .61 percent as of December 31, 2017, from .74 percent as of December 31, 2016. The decrease in allowance to loans reflects the addition of loans acquired from CBF at fair value which includes an estimate of life of loan credit losses. Nonperforming C&I loans decreased $1.6 million from December 31, 2016, to $31.2 million on December 31, 2017. The nonperforming loan (“NPL”) ratio decreased 8 basis points from December 31, 2016, to .19 percent of C&I loans as of December 31, 2017. The 30+ delinquency ratio increased to .19 percent as of December 31, 2017, from .08 percent as of December 31, 2016, driven by one large relationship, a portion of which is a purchased credit-impaired loan, and the addition of loans as a result of the CBF acquisition. Net charge-offs were $13.1 million in 2017 compared to $11.7 million in 2016.

(a) 30+ Delinquency % includes all accounts delinquent more than one month and still accruing interest. Commercial Real Estate The CRE portfolio was $4.2 billion on December 31, 2017. The CRE portfolio includes both financings for commercial construction and nonconstruction loans. The largest geographical concentrations of balances as of December 31, 2017, are in North Carolina (31 percent), Tennessee (20 percent), Florida (13 percent), South Carolina (9 percent), Georgia (7 percent), and Texas (6 percent), with no other state representing more than FIRST HORIZON NATIONAL CORPORATION 31 3 percent of the portfolio. This portfolio is segregated between the income-producing CRE class which contains loans, draws on lines and letters of credit to commercial real estate developers for the construction and mini- permanent financing of income-producing real estate, and the residential CRE class. Subcategories of income CRE consist of multi-family (24 percent), retail (21 percent), office (21 percent), industrial (11 percent), hospitality (10 percent), land/land development (1 percent) and other (12 percent). The residential CRE class includes loans to residential builders and developers for the purpose of constructing single-family homes, condominiums, and town homes. Active residential CRE lending has been modest with new originations primarily targeted in select markets. We have relationships with existing strategic clients, and we are seeking new clients on a selective basis. FHN desires a “strategic” residential CRE borrower to have solid experience, effective process and controls, appropriate risk tolerance, and a sound financial position that we believe can sustain their operations through the inevitable real estate cycles. Income CRE loans are underwritten in accordance with credit policies and underwriting guidelines that are reviewed at least annually and revised as necessary based on market conditions. Loans are underwritten based upon project type, size, location, sponsorship, and other market-specific data. Generally, minimum requirements for equity, debt service coverage ratios (“DSCRs”), and level of pre-leasing activity are established based on perceived risk in each subcategory. Loan-to-value (value is defined as the lower of cost or market) limits are set below regulatory prescribed ceilings and generally range between 50 and 80 percent depending on underlying product set. Term and amortization requirements are set based on prudent standards for interim real estate lending. Equity requirements are established based on the quality and liquidity of the primary source of repayment. For example, more equity would be required for a speculative construction project or land loan than for a property fully leased to a credit tenant or a roster of tenants. Typically, a borrower must have at least 15 percent of cost invested in a project before FHN will fund loan dollars. Income properties are required to achieve a DSCR greater than or equal to 125 percent at inception or stabilization of the project based on loan amortization and a minimum underwriting interest rate. Some product types that possess a greater risk profile require a higher level of equity, as well as a higher DSCR threshold. A proprietary minimum underwriting interest rate is used to calculate compliance with underwriting standards. Generally, specific levels of pre-leasing must be met for construction loans on income properties. A global cash flow analysis is performed at the sponsor level. The majority of the portfolio is on a floating rate basis tied to appropriate spreads over LIBOR. The credit administration and ongoing monitoring consists of multiple internal control processes. Construction loans are closed and administered by a centralized control unit. Underwriters and credit approval personnel stress the borrower’s/project’s financial capacity utilizing numerous attributes such as interest rates, vacancy, and discount rates. Key information is captured from the various portfolios and then stressed at the aggregate level. Results are utilized to assist with the assessment of the adequacy of the ALLL and to steer portfolio management strategies. CRE Asset Quality Trends The CRE portfolio had continued stable performance as of December 31, 2017, with nonperforming loans down $1.4 million from December 31, 2016 and net recoveries in 2017. The allowance decreased $5.4 million from December 31, 2016, to $28.4 million as of December 31, 2017. Allowance as a percentage of loans decreased 92 basis points from December 31, 2016, to .67 percent as of December 31, 2017. The decrease in allowance to loans reflects the addition of loans acquired from CBF at fair value which includes an estimate of life of loan credit losses. Nonperforming loans as a percentage of total CRE loans improved 10 basis points from 2016 to .03 percent as of December 31, 2017. Accruing delinquencies as a percentage of period-end loans increased to .11 percent as of December 31, 2017, from .01 percent as of December 31, 2016, primarily driven by the addition of loans as a result of the CBF acquisition. FHN recognized net recoveries of $.8 million in 2017 compared to net recoveries of $.6 million in 2016.

The largest geographical concentrations of balances as of December 31, 2017, are in Tennessee (51 percent), North Carolina (16 percent), Florida (13 percent), and California (4 percent), with no other state representing more than 3 percent of the portfolio. As of December 31, 2017, approximately 76 percent of the consumer real estate portfolio was in a first lien position. At origination, weighted average FICO score of this portfolio was 752 and refreshed FICO scores averaged 756 as of December 31, 2017, as compared to 750 and 747, respectively, as of December 31, 2016. As of December 31, 2017, approximately $1.4 billion, or 21 percent, of the consumer real estate portfolio consisted of stand-alone second liens while $.2 billion, or 3 percent, were second liens whose first liens are owned or serviced by FHN. We obtain first lien performance information from third parties and through loss mitigation activities, and we place a stand-alone second lien loan on nonaccrual if we discover that there are performance issues with the first lien loan. Generally, performance of this portfolio is affected by life events that affect borrowers’ finances, the level of unemployment, and home prices. Home equity lines of credit (“HELOCs”) comprise $1.8 billion of the consumer real estate portfolio as of December 31, 2017. FHN’s HELOCs typically have a 5 or 10 year draw period followed by a 10 or 20 year repayment period, respectively. During the draw period, a borrower is able to draw on the line and is only required to make interest payments. The line is automatically frozen if a borrower becomes 45 days or more past due on payments. Once the draw period has concluded, the line is closed and the borrower is required to make both principal and interest payments monthly until the loan matures. The principal payment generally is fully amortizing, but payment amounts will adjust when variable rates reset to reflect changes in the prime rate. As of December 31, 2017, approximately 72 percent of FHN’s HELOCs are in the draw period compared to approximately 62 percent as of December 31, 2016. Based on when draw periods are scheduled to end per the line agreement, it is expected that $528.4 million, or 40 percent of HELOCs currently in the draw period, will enter the repayment period during the next 60 months. Delinquencies and charge-off rates for HELOCs that have entered the repayment period are initially higher than HELOCs still in the draw period because of the increased minimum payment requirement; however, after some seasoning, performance of these loans usually begins to stabilize. The home equity lines of the consumer real estate portfolio are being monitored closely for those nearing the end of the draw period and borrowers are initially being contacted at least 24 months before the repayment period begins to remind the customer of the terms of their agreement and to inform them of options. The following table shows the HELOCs currently in the draw period and expected timing of conversion to the repayment period.

To obtain a consumer real estate loan, the loan applicant(s) in most cases must first meet a minimum 34 FIRST HORIZON NATIONAL CORPORATION qualifying FICO score. Minimum FICO score requirements are established by management for both loans secured by real estate as well as non-real estate loans. Management also establishes maximum loan amounts, loan-to-value ratios, and Debt-to-Income (“DTI”) ratios for each consumer real estate product. Applicants must have the financial capacity (or available income) to service the debt by not exceeding a calculated DTI ratio. The amount of the loan is limited to a percentage of the lesser of the current value or sales price of the collateral. Identified guideline and policy exceptions require established mitigating factors that have been approved for use by Credit Risk Management. HELOC interest rates are variable and adjust with movements in the index rate stated in the loan agreement. Such loans can have elevated risks of default, particularly in a rising interest rate environment, potentially stressing borrower capacity to repay the loan at the higher interest rate. FHN’s current underwriting practice requires HELOC borrowers to qualify based on a fully indexed, fully amortized payment methodology. FHN’s underwriting guidelines require borrowers to qualify at an interest rate that is 200 basis points above the note rate. This mitigates risk to FHN in the event of a sharp rise in interest rates over a relatively short time horizon. HELOC Portfolio Risk Management FHN performs continuous HELOC account review processes in order to identify higher-risk home equity lines and initiate preventative and corrective actions. The reviews consider a number of account activity patterns and characteristics such as the number of times delinquent within recent periods, changes in credit bureau score since origination, score degradation, performance of the first lien, and account utilization. In accordance with FHN’s interpretation of regulatory guidance, FHN may block future draws on accounts in order to mitigate risk of loss to FHN. Consumer Real Estate Asset Quality Trends Overall, performance of the consumer real estate portfolio remained strong in 2017. The non-strategic segment is a run-off portfolio and while the absolute dollars of delinquencies and nonaccruals declined compared to December 31, 2016, 30+ accruing delinquencies and nonperforming loans ratios deteriorated. That trend of increasing deterioration in the non-strategic segment is likely to continue and may become more skewed as the portfolio shrinks unevenly, with stronger borrowers exiting the portfolio more rapidly than others. The ALLL decreased $13.0 million from December 31, 2016, to $37.4 million as of December 31, 2017, with the majority of the decline attributable to the non-strategic segment. The balance of nonperforming loans declined $11.3 million to $71.5 million on December 31, 2017. Loans delinquent 30 or more days and still accruing declined from $42.1 million as of December 31, 2016, to $41.5 million as of December 31, 2017. The portfolio realized net recoveries of $9.6 million in 2017 compared to net recoveries of $1.7 million in 2016. The following table shows consumer real estate asset quality trends by segment.

This portfolio is primarily composed of jumbo mortgages and one-time-close (“OTC”) completed construction loans in the non-strategic segment that were originated through legacy businesses. The regional banking segment primarily includes recently acquired mortgage loans associated with FHN’s CRA initiatives. The corporate segment includes loans that were previously included in off-balance sheet proprietary securitization trusts. These loans were brought back into the loan portfolios at fair value through the execution of cleanup calls due to the relatively small balances left in the securitization and should continue to run-off. Approximately 19 percent of loan balances as of December 31, 2017, are in California, but the remainder of the portfolio is somewhat geographically diverse. Non-strategic and corporate segment run-off, partially offset by increases in the regional banking segment, contributed to the $23.8 million net decrease in permanent mortgage period-end balances from December 31, 2016, to December 31, 2017. The permanent mortgage portfolios within the non-strategic and corporate segments are run-off portfolios. As a result, asset quality metrics are becoming skewed as the portfolio shrinks and some of the stronger borrowers payoff or refinance elsewhere. The ALLL decreased $.7 million as of December 31, 2017, from $16.3 million as of December 31, 2016. TDR reserves (which are estimates of losses for the expected life of the loan) comprise 78 percent of the ALLL for the permanent mortgage portfolio as of December 31, 2017. Consolidated accruing delinquencies as a percentage of total loans decreased 51 basis points from December 31, 2016 to 1.85 percent as of December 31, 2017. Nonperforming loans decreased $.8 million from December 31, 2016, to $26.4 million as of December 31, 2017. The portfolio experienced net recoveries of $.3 million in 2017 compared to net recoveries of $.8 million in 2016. The following table shows permanent mortgage asset quality trends by segment.

FIRST HORIZON NATIONAL CORPORATION 39 Allowance for Loan Losses Management’s policy is to maintain the ALLL at a level sufficient to absorb estimated probable incurred losses in the loan portfolio. The total allowance for loan losses decreased to $189.6 million on December 31, 2017, from $202.1 million on December 31, 2016. The ALLL as of December 31, 2017, reflects strong asset quality with the consumer real estate portfolio continuing to stabilize, historically low levels of net charge-offs, and declining non- strategic balances. The ratio of allowance for loan losses to total loans, net of unearned income, decreased to .69 percent on December 31, 2017, from 1.03 percent on December 31, 2016. The decrease in the allowance to loans ratio reflects the addition of loans acquired from CBF at fair value which includes an estimate of life of loan credit losses. The provision for loan losses is the charge to or release of earnings necessary to maintain the ALLL at a sufficient level reflecting management’s estimate of probable incurred losses in the loan portfolio. Year-to-date provision expense was zero in 2017 compared to $11.0 million in 2016 reflecting continued strong performance in the commercial and consumer portfolios. FHN expects asset quality trends to remain relatively stable for the near term if the growth of the economy continues. The C&I portfolio is expected to continue to show stable trends but short-term variability (both positive and negative) is possible, primarily due to the size of the credits within this portfolio. The CRE portfolio metrics should be relatively consistent as FHN expects stable property values over the near term; however, oversupply of any CRE product type, changes in the lending environment, or economic uncertainty could result in decreased property values (which could happen abruptly). The remaining non-strategic consumer real estate and permanent mortgage portfolios should continue to steadily wind down. Asset quality metrics within non-strategic are becoming skewed as the portfolio continues to shrink, with stronger credits exiting the portfolio more rapidly than others. Continued stabilization in performance of the consumer real estate portfolio assumes an ongoing economic recovery as consumer delinquency and loss rates are correlated with life events that affect borrowers’ finances, unemployment trends, and strength of the housing market. Consolidated Net Charge-offs Overall, net charge-offs continue to be at historical lows. Net charge-offs were $12.5 million in 2017 compared to $19.2 million in 2016. The commercial portfolio experienced $12.3 million of net charge-offs in 2017 compared to $11.1 million in 2016. In addition, the consumer real estate portfolio experienced net recoveries of $9.6 million in 2017 compared to net recoveries of $1.7 million in 2016. Permanent mortgage and credit card and other remained relatively flat compared to a year ago. 40 FIRST HORIZON NATIONAL CORPORATION The following table provides consolidated asset quality information for the years 2013 through 2017: Table 20 – Analysis of Allowance for Loan Losses and Charge-offs (Dollars in thousands) Allowance for loan losses: Beginning balance Provision for loan losses Charge-offs: Commercial, financial, and industrial Commercial real estate Consumer real estate Permanent mortgage Credit card and other Total charge-offs Recoveries: Commercial, financial, and industrial Commercial real estate Consumer real estate Permanent mortgage Credit card and other Total recoveries Net charge-offs Ending balance $ Reserve for unfunded commitments Total of allowance for loan losses and reserve for unfunded commitments Loans and commitments: Total period end loans, net of unearned income Remaining unfunded commitments Average loans, net of unearned income Reserve Rates Total commercial loans Allowance/loans % (a) Period end loans % of total loans Consumer real estate Allowance/loans % (a) Period end loans % of total loans Permanent mortgage Allowance/loans % Period end loans % of total loans Credit card and other Allowance/loans % (a) Period end loans % of total loans Allowance and net charge-off ratios Allowance to total loans % (a) Net charge-offs to average loans % Allowance to net charge-offs 2017 2016 2015 2014 2013 $ 202,068 - $ 210,242 11,000 $ 232,448 9,000 $ 253,809 27,000 $ 276,963 55,000 17,657 195 13,156 2,179 13,207 46,394 4,568 966 22,723 2,509 3,115 33,881 12,513 189,555 5,079 $ 18,460 1,371 21,993 1,591 14,224 57,639 6,795 1,927 23,719 2,403 3,621 38,465 19,174 202,068 5,312 $ 22,406 3,550 30,068 3,141 16,691 75,856 13,339 1,876 23,895 1,687 3,853 44,650 31,206 210,242 5,926 $ 20,492 3,741 45,391 5,891 14,931 90,446 9,666 4,150 22,824 2,314 3,131 42,085 48,361 232,448 4,770 $ 22,936 3,502 73,642 9,934 11,404 121,418 12,487 4,275 21,360 2,473 2,669 43,264 78,154 253,809 3,017 $ 194,634 $ 207,380 $ 216,168 $ 237,218 $ 256,826 $27,658,929 $19,589,520 $17,686,502 $16,230,166 $15,389,074 $10,678,485 $20,104,042 $ 8,744,649 $18,303,870 $ 7,903,294 $16,624,439 $ 7,231,879 $15,520,972 $ 7,469,553 $15,726,374 0.62% 73 0.86% 73 0.82% 68 0.83% 63 1.07% 59 0.59 23 3.90 1 1.61 2 0.69 0.06 15.15x 1.11 23 3.85 2 3.39 2 1.03 0.10 10.54x 1.69 27 4.17 3 3.35 2 1.19 0.19 6.74x 2.24 31 3.55 3 4.11 2 1.43 0.31 4.81x 2.38 35 3.40 4 2.22 2 1.65 0.50 3.25x (a) 2017 decrease in allowance to loans reflects the addition of loans acquired from CBF at fair value which includes an estimate of life of loan credit losses. Nonperforming Assets Nonperforming loans are loans placed on nonaccrual if it becomes evident that full collection of principal and interest is at risk, impairment has been recognized as a partial charge-off of principal balance due to insufficient collateral value and past due status, or on a case-by-case basis if FHN continues to receive payments but there are other borrower-specific issues. Included in nonaccruals are loans that FHN continues to receive payments including residential real estate loans where the borrower has been discharged of personal obligation through bankruptcy, and second liens, regardless of delinquency status, behind first liens that are 90 or more days past due, are bankruptcies, or are TDRs. These, along with OREO, excluding OREO from government insured mortgages, represent nonperforming assets (“NPAs”). FIRST HORIZON NATIONAL CORPORATION 41 Total nonperforming assets (including NPLs HFS) increased to $177.2 million on December 31, 2017, from $164.6 million on December 31, 2016, primarily driven by an increase in OREO. OREO, excluding OREO from government insured mortgages, increased $28.3 million to $39.6 million as of December 31, 2017, driven by the CBF acquisition. This increase was offset by a decline in portfolio nonperforming loans of $15.0 million from December 31, 2016, to $130.6 million on December 31, 2017. While all portfolios declined or remained flat, the decline in nonperforming loans was primarily driven by the consumer real estate portfolio which declined $11.3 million. This decrease in the consumer real estate portfolio was largely driven by payoffs. The nonperforming assets ratio (nonperforming assets excluding NPLs HFS to total period-end loans plus OREO and other assets) decreased to .61 percent as of December 31, 2017, compared to .80 percent as of December 31, 2016. The ratio of the ALLL to NPLs in the loan portfolio was 1.45 times as of December 31, 2017, compared to 1.39 times as of December 31, 2016. Certain nonperforming loans in both the commercial and consumer portfolios are deemed collateral-dependent and are charged down to an estimate of collateral value less costs to sell. Because loss content has been recognized through a partial charge-off, typically reserves are not recorded.

Table 23 provides an activity rollforward of OREO balances for December 31, 2017 and 2016. The balance of OREO, exclusive of inventory from government insured mortgages, increased to $39.6 million as of December 31, 2017, from $11.2 million as of December 31, 2016, primarily driven by the acquisition of CBF. In addition, FHN has executed sales of existing OREO and continued efforts to avoid foreclosures by restructuring loans and working with borrowers. Moreover, property values have stabilized which also affects the balance of OREO.

Past Due Loans and Potential Problem Assets Past due loans are loans contractually past due as to interest or principal payments, but which have not yet been put on nonaccrual status. Loans in the portfolio that are 90 days or more past due and still accruing were $41.6 million on December 31, 2017, compared to $23.4 million on December 31, 2016. The increase was due in FIRST HORIZON NATIONAL CORPORATION 43 large part to one relationship, which is a purchased credit-impaired loan. Loans 30 to 89 days past due increased to $50.9 million on December 31, 2017, from $42.6 million on December 31, 2016. Potential problem assets represent those assets where information about possible credit problems of borrowers has caused management to have serious doubts about the borrower’s ability to comply with present repayment terms and includes loans past due 90 days or more and still accruing. This definition is believed to be substantially consistent with the standards established by the OCC for loans classified as substandard. Potential problem assets in the loan portfolio were $327.2 million on December 31, 2017 compared to $290.4 million on December 31, 2016. The increase year-over-year in potential problem assets was due to a net increase in classified commercial loans driven by a few credits. The current expectation of losses from potential problem assets has been included in management’s analysis for assessing the adequacy of the allowance for loan losses.

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. In a situation where an economic concession has been granted to a borrower that is experiencing financial difficulty, FHN identifies and reports that loan as a Troubled Debt Restructuring (“TDR”). See Note 4 – Loans for further discussion regarding TDRs and loan modifications. Commercial Loan Modifications As part of FHN’s credit risk management governance processes, the Loan Rehab and Recovery Department (“LRRD”) is responsible for managing most commercial relationships with borrowers whose financial condition has deteriorated to such an extent that the credits are being considered for impairment, classified as substandard or worse, placed on nonaccrual status, foreclosed or in process of foreclosure, or in active or contemplated litigation. LRRD has the authority and responsibility to enter into workout and/or rehabilitation agreements with troubled 44 FIRST HORIZON NATIONAL CORPORATION commercial borrowers in order to mitigate and/or minimize the amount of credit losses recognized from these problem assets. While every circumstance is different, LRRD will generally use forbearance agreements (generally 6-12 months) as an element of commercial loan workouts, which include reduced interest rates, reduced payments, release of guarantor, or entering into short sale agreements. The individual impairment assessments completed on commercial loans in accordance with the Accounting Standards Codification Topic related to Troubled Debt Restructurings (“ASC 310-40”) include loans classified as TDRs as well as loans that may have been modified yet not classified as TDRs by management. For example, a modification of loan terms that management would generally not consider to be a TDR could be a temporary extension of maturity to allow a borrower to complete an asset sale whereby the proceeds of such transaction are to be paid to satisfy the outstanding debt. Additionally, a modification that extends the term of a loan but does not involve reduction of principal or accrued interest, in which the interest rate is adjusted to reflect current market rates for similarly situated borrowers, is not considered a TDR. Nevertheless, each assessment will take into account any modified terms and will be comprehensive to ensure appropriate impairment assessment. If individual impairment is identified, management will either hold specific reserves on the amount of impairment, or, if the loan is collateral dependent, write down the carrying amount of the asset to the net realizable value of the collateral. Consumer Loan Modifications FHN does not currently participate in any of the loan modification programs sponsored by the U.S. government but does generally structure modified consumer loans using the parameters of the former Home Affordable Modification Program (“HAMP”). Generally, a majority of loans modified under any such proprietary programs are classified as TDRs. 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. Following classification as a TDR, modified loans within the consumer portfolio, which were previously evaluated for impairment on a collective basis determined by their smaller balances and homogenous nature, become subject to the impairment guidance in ASC 310-10-35, which requires individual evaluation of the debt for impairment. However, as applicable accounting guidance allows, FHN may aggregate certain smaller-balance homogeneous TDRs and use historical statistics, such as aggregated charge-off amounts and average amounts recovered, along with a composite effective interest rate to measure impairment when such impaired loans have risk characteristics in common. On December 31, 2017 and December 31, 2016, FHN had $234.4 million and $285.2 million portfolio loans classified as TDRs, respectively. For TDRs in the loan portfolio, FHN had loan loss reserves of $37.3 million and $44.9 million, or 16 percent of TDR balances, as of December 31, 2017 and December 31, 2016. Additionally, FHN had $63.2 million and $69.3 million of HFS loans classified as TDRs as of December 31, 2017 and December 31, 2016, respectively. Total held-to-maturity TDRs decreased by $50.8 million with the majority of the decline attributable to consumer real estate, commercial and permanent mortgage loans.

FHN has an enterprise- wide approach to risk governance, measurement, management, and reporting including an economic capital allocation process that is tied to risk profiles used to measure risk-adjusted returns. Through an enterprise-wide risk governance structure and a statement of risk tolerance approved by the Board, management continually evaluates the balance of risk/return and earnings volatility with shareholder value. FHN’s enterprise-wide risk governance structure begins with the Board. The Board, working with the Executive & Risk Committee of the Board, establishes the Company’s risk tolerance by approving policies and limits that provide standards for the nature and the level of risk the Company is willing to assume. The Board regularly receives reports on management’s performance against the Company’s risk tolerance primarily through the Board’s Executive & Risk and Audit Committees. To further support the risk governance provided by the Board, FHN has established accountabilities, control processes, procedures, and a management governance structure designed to align risk management with risk- taking throughout the Company. The control procedures are aligned with FHN’s four components of risk governance: (1) Specific Risk Committees; (2) the Risk Management Organization; (3) Business Unit Risk Management; and (4) Independent Assurance Functions. 1. Specific Risk Committees: The Board has delegated authority to the Chief Executive Officer (“CEO”) to manage Business Strategy and Reputation Risk, and the general business affairs of the Company under the Board’s oversight. The CEO utilizes the executive management team and the Executive Risk Management Committee to carry out these duties and to analyze existing and emerging strategic and reputation risks and determines the appropriate course of action. The Executive Risk Management Committee is comprised of the CEO and certain officers designated by the CEO. The Executive Risk Management Committee is supported by a set of specific risk committees focused on unique risk types (e.g. liquidity, credit, operational, etc). These risk committees provide a mechanism that assembles the necessary expertise and perspectives of the management team to discuss emerging risk issues, monitor the Company’s risk-taking activities, and evaluate specific transactions and exposures. These committees also monitor the direction and trend of risks relative to business strategies and market conditions and direct management to respond to risk issues. 2. The Risk Management Organization: The Company’s risk management organization, led by the Chief Risk Officer and Chief Credit Officer, provides objective oversight of risk-taking activities. The risk management organization translates FHN’s overall risk tolerance into approved limits and formal policies and is supported by corporate staff functions, including the Corporate Secretary, Legal, Finance, Human Resources, and Technology. Risk management also works with business units and functional experts to establish appropriate operating standards and monitor business practices in relation to those standards. Additionally, risk management proactively works with business units and senior management to focus management on key risks in the Company and emerging trends that may change FHN’s risk profile. The Chief Risk Officer has overall responsibility and accountability for enterprise risk management and aggregate risk reporting. 3. Business Unit Risk Management: The Company’s business units are responsible for identifying, acknowledging, quantifying, mitigating, and managing all risks arising within their respective units. They determine and execute their business strategies, which puts them closest to the changing nature of risks and they are best able to take the needed actions to manage and mitigate those risks. The business units are supported by the risk management organization that helps identify and consider risks when making business decisions. Management processes, structure, and policies are designed to help ensure compliance with laws and regulations as well as provide organizational clarity for authority, decision-making, and accountability. The risk governance structure supports and promotes the escalation of material items to executive management and the Board. FIRST HORIZON NATIONAL CORPORATION 47 4. Independent Assurance Functions: Internal Audit, Credit Assurance Services (“CAS”), and Model Validation provide an independent and objective assessment of the design and execution of the Company’s internal control system, including management processes, risk governance, and policies and procedures. These groups’ activities are designed to provide reasonable assurance that risks are appropriately identified and communicated; resources are safeguarded; significant financial, managerial, and operating information is complete, accurate, and reliable; and employee actions are in compliance with the Company’s policies and applicable laws and regulations. Internal Audit and CAS report to the Chief Audit Executive, who is appointed by and reports to the Audit Committee of the Board. Internal Audit reports quarterly to the Audit Committee of the Board, while CAS reports quarterly to the Executive & Risk Committee of the Board. Model Validation reports to the Chief Risk Officer and reports annually to the Audit Committee of the Board. MARKET RISK MANAGEMENT Market risk is the risk that changes in market conditions will adversely impact the value of assets or liabilities, or otherwise negatively impact FHN’s earnings. Market risk is inherent in the financial instruments associated with FHN’s operations, primarily trading activities within FHN’s fixed income segment, but also through non-trading activities which are primarily affected by interest rate risk that is managed by the Asset Liability Committee (“ALCO”) within FHN. FHN is exposed to market risk related to the trading securities inventory and loans held for sale maintained by its Fixed Income division in connection with its fixed income distribution activities. Market risk is the risk of loss in the value of the fixed income trading securities inventory and loans held for sale due to changes in market prices. Various types of securities inventory positions are procured for distribution to customers by the sales staff. When these securities settle on a delayed basis, they are considered forward contracts. Refer to the "Determination of Fair Value - Trading securities and trading liabilities" section of Note 24 - Fair Value of Assets and Liabilities beginning on page 172 of this report, which section is incorporated into this MD&A by this reference. FHN’s market risk appetite is approved by the Executive and Risk Committee of the Board of Directors and executed through management policies and procedures of ALCO and the FTN Financial Risk Committee. These policies contain various market risk limits including, for example, overall balance sheet size limits for Fixed Income, VaR limits for the trading securities inventory, and individual position limits and sector limits for products with credit risk, among others. Risk measures are computed and reviewed on a daily basis to ensure compliance with market risk management policies. VaR and Stress Testing VaR is a statistical risk measure to estimate the potential loss in value from adverse market movements over an assumed fixed holding period within a stated confidence level. FHN employs a model to compute daily VaR measures for its trading securities inventory. FHN computes VaR using historical simulation with a 1-year lookback period at a 99 percent confidence level and 1-day and 10-day time horizons. Additionally, FHN computes a Stressed VaR ("SVaR") measure. The SVaR computation uses the same model but with model inputs reflecting historical data from a continuous 12-month period that reflects a period of significant financial stress appropriate for our trading securities portfolio. A summary of FHN’s VaR and SVaR measures for 1-day and 10-day time horizons is as follows: Table 26 – VaR and SVaR Measures (Dollars in thousands) 1-day VaR SVaR 10-day VaR SVaR 48 Year Ended December 31, 2017 Mean High Low As of December 31, 2017 $ 1,529 4,704 $ 3,310 8,301 $ 521 1,775 3,560 15,511 8,039 28,232 870 4,916 $ 1,287 6,230 3,059 19,813 FIRST HORIZON NATIONAL CORPORATION (Dollars in thousands) 1-day VaR SVaR 10-day VaR SVaR Year Ended December 31, 2016 Mean High Low As of December 31, 2016 $ 821 3,643 $ 1,745 5,789 $ 393 1,748 2,088 11,671 5,852 18,483 751 3,263 $ 932 2,830 2,136 6,443 FHN’s overall VaR measure includes both interest rate risk and credit spread risk. Separate measures of these component risks are as follows: Table 27 – Schedule of Risks Included in VaR (Dollars in thousands) Interest rate risk Credit spread risk As of December 31, 2017 As of December 31, 2016 1-day $930 305 10-day $2,084 471 1-day $917 537 10-day $1,771 1,391 The potential risk of loss reflected by FHN’s VaR measures assumes the trading securities inventory is static. Because FHN’s Fixed Income division procures fixed income securities for purposes of distribution to customers, its trading securities inventory turns over regularly. Additionally, Fixed Income traders actively manage the trading securities inventory continuously throughout each trading day. Accordingly, FHN’s trading securities inventory is highly dynamic, rather than static. As a result, it would be rare for Fixed Income to incur a negative revenue day in its fixed income activities of the level indicated by its VaR measurements. In addition to being used in FHN’s daily market risk management process, the VaR and SVaR measures are also used by FHN in computing its regulatory market risk capital requirements in accordance with the Market Risk Capital rules. For additional information regarding FHN’s capital adequacy refer to the "Capital" section of this MD&A. FHN also performs stress tests on its trading securities portfolio to calculate the potential loss under various assumed market scenarios. Key assumed stresses used in those tests are: Down 25 bps – assumes an instantaneous downward move in interest rates of 25 basis points at all points on the interest rate yield curve. Up 25 bps – assumes an instantaneous upward move in interest rates of 25 basis points at all points on the interest rate yield curve. Curve flattening – assumes an instantaneous flattening of the interest rate yield curve through an increase in short-term rates and a decrease in long-term rates. The 2-year point on the Treasury yield curve is assumed to increase 15 basis points and the 10-year point on the Treasury yield curve is assumed to decrease 15 basis points. Shifts in other points on the yield curve are predicted based on their correlation to the 2-year and 10-year points. Curve steepening – assumes an instantaneous steepening of the interest rate yield curve through a decrease in short-term rates and an increase in long-term rates. The 2-year point on the Treasury yield curve is assumed to decrease 15 basis points and the 10-year point on the Treasury yield curve is assumed to increase 15 basis points. Shifts in other points on the yield curve are predicted based on their correlation to the 2-year and 10-year points. Credit spread widening – assumes an instantaneous increase in credit spreads (the difference between yields on Treasury securities and non-Treasury securities) of 25 basis points. FIRST HORIZON NATIONAL CORPORATION 49 Model Validation Trading risk management personnel within Fixed Income have primary responsibility for model risk management with respect to the model used by FHN to compute its VaR measures and perform stress testing on the trading inventory. Among other procedures, these personnel monitor model results and perform periodic backtesting as part of an ongoing process of validating the accuracy of the model. These model risk management activities are subject to annual review by FHN’s Model Validation Group, an independent assurance group charged with oversight responsibility for FHN’s model risk management. INTEREST RATE RISK MANAGEMENT Interest rate risk is the risk to earnings or capital arising from movement in interest rates. ALCO is responsible for overseeing the management of existing and emerging interest rate risk in the company within risk tolerances established by the Board. FHN primarily manages interest rate risk by structuring the balance sheet to maintain a desired level of associated earnings and to protect the economic value of FHN’s capital. Net interest income and the value of equity are affected by changes in the level of market interest rates because of the differing repricing characteristics of assets and liabilities, the exercise of prepayment options held by loan and deposit customers, and changes in the basis between and changing shapes of the various yield curves used to price assets and liabilities. To isolate the repricing, basis, option, and yield curve components of overall interest rate risk, FHN employs Gap, Earnings at Risk, and Economic Value of Equity analyses generated by a balance sheet simulation model. Net Interest Income Simulation Analysis The information provided in this section, including the discussion regarding the outcomes of simulation analysis and rate shock analysis, is forward-looking. Actual results, if the assumed scenarios were to occur, could differ because of interest rate movements, the ability of management to execute its business plans, and other factors, including those presented in the Forward-Looking Statements section of this MD&A. Management uses a simulation model to measure interest rate risk and to formulate strategies to improve balance sheet positioning, earnings, or both, within FHN’s interest rate risk, liquidity, and capital guidelines. Interest rate exposure is measured by forecasting 12 months of NII under various interest rate scenarios and comparing the percentage change in NII for each scenario to a base case scenario where interest rates remain unchanged. Assumptions are made regarding future balance sheet composition, interest rate movements, and loan and deposit pricing. In addition, assumptions are made about the magnitude of asset prepayments and earlier than anticipated deposit withdrawals. The results of these scenarios help FHN develop strategies for managing exposure to interest rate risk. While management believes the assumptions used and scenarios selected in its simulations are reasonable, simulation modeling provides only an estimate, not a precise calculation, of exposure to any given change in interest rates. Based on a static balance sheet as of December 31, 2017, net interest income exposure over the next 12 months assuming a rate shock of plus 25 basis points, 50 basis points, 100 basis points, and 200 basis points is estimated to have a favorable variance of 0.9 percent, 1.8 percent, 3.3 percent, and 6.2 percent, respectively of base net interest income. A steepening yield curve scenario where long-term rates increase by 50 basis points and short-term rates are static, results in a favorable variance in net interest income of 0.8 percent of base net interest income. A flattening yield curve scenario where long-term rates decrease by 50 basis points and short-term rates are static, results in an unfavorable variance in net interest income of 1.3 percent of base net interest income. A rate shock of minus 50 basis points results in an unfavorable variance in net interest income of 3.7 percent of base net interest income. These hypothetical scenarios are used to create a risk measurement framework, and do not necessarily represent management’s current view of future interest rates or market developments. The recent movement of short-term interest rates higher after a prolonged period of very low interest rates has had a positive effect on FHN’s net interest income and net interest margin. Given recent strength in the economy, the upward trend in interest rates, and market expectations for higher rates in the future, FHN has employed a moderately asset sensitive position. While it is expected that rates will continue to move higher, the movement of rates off the zero boundary during the past year has created the possibility that rates could decline in the future. 50 FIRST HORIZON NATIONAL CORPORATION FHN continues to monitor economic conditions and remains prepared to take any actions to mitigate exposure to falling interest rates should that occur. Fair Value Shock Analysis Interest rate risk and the slope of the yield curve also affect the fair value of Fixed Income’s trading inventory that is reflected in Fixed Income’s noninterest income. Generally, low or declining interest rates with a positively sloped yield curve tend to increase Fixed Income’s income through higher demand for fixed income products. Additionally, the fair value of Fixed Income’s trading inventory can fluctuate as a result of differences between current interest rates and the interest rates of fixed income securities in the trading inventory. Derivatives In the normal course of business, FHN utilizes various financial instruments (including derivative contracts and credit-related agreements) to manage interest rate risk of certain term borrowings, and certain loans. The Fixed Income segment utilizes various financial instruments (including derivative contracts and credit-related agreements) to manage the risk of loss arising from adverse changes in the fair value of certain financial instruments generally caused by changes in interest rates including Fixed Income’s securities inventory, certain term borrowings, and certain loans. Additionally, Fixed Income or Regional Banking may enter into derivative contracts in order to meet customers’ needs. However, such derivative contracts are typically offset with a derivative contract entered into with an upstream counterparty in order to mitigate risk associated with changes in interest rates. The simulation models and related hedging strategies discussed above exclude the dynamics related to how fee income and noninterest expense may be affected by actual changes in interest rates or expectations of changes. See Note 22 – Derivatives for additional discussion of these instruments. CAPITAL MANAGEMENT AND ADEQUACY The capital management objectives of FHN are to provide capital sufficient to cover the risks inherent in FHN’s businesses, to maintain excess capital to well-capitalized standards, and to assure ready access to the capital markets. The Capital Management Committee, chaired by the Senior Vice President and Corporate Treasurer, reports to ALCO and is responsible for capital management oversight and provides a forum for addressing management issues related to capital adequacy. This committee reviews sources and uses of capital, key capital ratios, segment economic capital allocation methodologies, and other factors in monitoring and managing current capital levels, as well as potential future sources and uses of capital. The Capital Management Committee also recommends capital management policies, which are submitted for approval to ALCO and the Executive & Risk Committee and the Board as necessary. OPERATIONAL RISK MANAGEMENT Operational risk is the risk of loss from inadequate or failed internal processes, people, or systems or from external events including data or network security breaches of FHN or of third parties affecting FHN or its customers. This risk is inherent in all businesses. Operational risk is divided into the following risk areas, which have been established at the corporate level to address these risks across the entire organization: • Business Continuity Planning/Records Management • Compliance/Legal • Program Governance • Fiduciary • Financial Crimes (including Bank Secrecy Act, know your customer, security, and fraud) FIRST HORIZON NATIONAL CORPORATION 51 • Financial (including disclosure controls and procedures) • Information Technology (including cybersecurity) • Vendor Management, measurement, and reporting of operational risk are overseen by the Operational Risk, Fiduciary, Financial Governance, FTN Financial Risk, and Investment Rationalization Board Committees. Key representatives from the business segments, operating units, and supporting units are represented on these committees as appropriate. These governance committees manage the individual operational risk types across the company by setting standards, monitoring activity, initiating actions, and reporting exposures and results. Key Committee activities and decisions are reported to the appropriate governance committee or included in the Enterprise Risk Report, a quarterly analysis of risk within the organization that is provided to the Executive and Risk Committee. Emphasis is dedicated to refinement of processes and tools to aid in measuring and managing material operational risks and providing for a culture of awareness and accountability. COMPLIANCE RISK MANAGEMENT Compliance risk is the risk of legal or regulatory sanctions, material financial loss, or loss to reputation as a result of failure to comply with laws, regulations, rules, related self-regulatory organization standards, and codes of conduct applicable to FHN’s activities. Management, measurement, and reporting of compliance risk are overseen by the Operational Risk Committee. Key executives from the business segments, legal, risk management, and service functions are represented on the Committee. Summary reports of Committee activities and decisions are provided to the appropriate governance committees. Reports include the status of regulatory activities, internal compliance program initiatives, and evaluation of emerging compliance risk areas. CREDIT RISK MANAGEMENT Credit risk is the risk of loss due to adverse changes in a borrower’s or counterparty’s ability to meet its financial obligations under agreed upon terms. FHN is subject to credit risk in lending, trading, investing, liquidity/funding, and asset management activities although lending activities have the most exposure to credit risk. The nature and amount of credit risk depends on the types of transactions, the structure of those transactions, collateral received, the use of guarantors and the parties involved. FHN assesses and manages credit risk through a series of policies, processes, measurement systems, and controls. The Credit Risk Management Committee (“CRMC”) is responsible for overseeing the management of existing and emerging credit risks in the company within the broad risk tolerances established by the Board. The CRMC reports through the Executive Risk Management Committee. The Credit Risk Management function, led by the Chief Credit Officer, provides strategic and tactical credit leadership by maintaining policies, overseeing credit approval, assessing new credit products, strategies and processes, and managing portfolio composition and performance. While the Credit Risk function oversees FHN’s credit risk management, there is significant coordination between the business lines and the Credit Risk function in order to manage FHN’s credit risk and maintain strong asset quality. The Credit Risk function recommends portfolio, industry/sector, and individual customer limits to the Executive & Risk Committee of the Board for approval. Adherence to these approved limits is vigorously monitored by Credit Risk who provides recommendations to slow or cease lending to the business lines as commitments near established lending limits. Credit Risk also ensures subject matter experts are providing oversight, support and credit approvals, particularly in the specialty lending areas where industry-specific knowledge is required. Management emphasizes general portfolio servicing such that emerging risks are spotted early enough to correct potential deficiencies, prevent further credit deterioration, and mitigate credit losses. The Credit Risk Management function assesses the asset quality trends and results, as well as lending processes, adherence to underwriting guidelines (portfolio-specific underwriting guidelines are discussed further in the Asset Quality Trends section), and utilizes this information to inform management regarding the current state of credit quality and as a factor of the estimation process for determining the allowance for loan losses. The CRMC reviews 52 FIRST HORIZON NATIONAL CORPORATION on a periodic basis various reports issued by assurance functions which provide an independent assessment of the adequacy of loan servicing, grading accuracy, and other key functions. Additionally, CRMC is presented with and discusses various portfolios, lending activity and lending-related projects. All of the above activities are subject to independent review by FHN’s Credit Assurance Services Group. CAS reports to the Chief Audit Executive, who is appointed by and reports to the Audit Committee of the Board, and provides quarterly reports to the Executive & Risk Committee of the Board. CAS is charged with providing the Executive & Risk Committee of the Board and executive management with independent, objective, and timely assessments of FHN’s portfolio quality, credit policies, and credit risk management processes. FIRST HORIZON NATIONAL CORPORATION 53 LIQUIDITY RISK MANAGEMENT ALCO also focuses on liquidity management: the funding of assets with liabilities of appropriate duration, while mitigating the risk of unexpected cash needs. ALCO and the Board of Directors have adopted a Liquidity Policy. The objective of the Liquidity Policy is to ensure that FHN meets its cash and collateral obligations promptly, in a cost-effective manner and with the highest degree of reliability. The maintenance of adequate levels of asset and liability liquidity should provide FHN with the ability to meet both expected and unexpected cash and collateral needs. Key liquidity ratios, asset liquidity levels and the amount available from funding sources are reported to ALCO on a regular basis. FHN’s Liquidity Policy establishes liquidity limits that are deemed appropriate for FHN’s risk profile. In accordance with the Liquidity Policy, ALCO manages FHN’s exposure to liquidity risk through a dynamic, real time forecasting methodology. Base liquidity forecasts are reviewed by ALCO and are updated as financial conditions dictate. In addition to the baseline liquidity reports, robust stress testing of assumptions and funds availability are periodically reviewed. FHN maintains a contingency funding plan that may be executed, should unexpected difficulties arise in accessing funding that affects FHN, the industry as a whole, or both. Subject to market conditions and compliance with applicable regulatory requirements from time to time, funds are available from a number of sources including the available-for-sale securities portfolio, dealer and commercial customer repurchase agreements, access to the overnight and term Federal Funds markets, incremental borrowing capacity at the FHLB ($1.3 billion was available at December 31, 2017), brokered deposits, loan sales, syndications, and access to the Federal Reserve Banks. Core deposits are a significant source of funding and have historically been a stable source of liquidity for banks. Generally, core deposits represent funding from a financial institution’s customer base which provide inexpensive, predictable pricing. The Federal Deposit Insurance Corporation insures these deposits to the extent authorized by law. Generally, these limits are $250 thousand per account owner for interest bearing and non-interest bearing accounts. The ratio of total loans, excluding loans HFS and restricted real estate loans, to core deposits was 101 percent on December 31, 2017 compared to 105 percent on December 31, 2016. FHN also may use unsecured short-term borrowings as a source of liquidity. Currently, the largest concentration of unsecured borrowings is federal funds purchased from bank correspondent customers. These funds are considered to be substantially more stable than funds purchased in the national broker markets for federal funds due to the long, historical, and reciprocal nature of banking services provided by FHN to these correspondent banks. The remainder of FHN’s wholesale short-term borrowings is securities sold under agreements to repurchase transactions accounted for as secured borrowings with Regional Banking’s business customers or Fixed Income’s broker dealer counterparties. Both FHN and FTBNA may access the debt markets in order to provide funding through the issuance of senior or subordinated unsecured debt subject to market conditions and compliance with applicable regulatory requirements. In 2014, FTBNA issued $400 million of fixed rate senior notes due in December 2019. In October 2015, FHN issued $500 million of fixed rate senior notes due in December 2020. Both FHN and FTBNA have the ability to generate liquidity by issuing preferred equity, and (for FHN) by issuing common equity, subject to market conditions and compliance with applicable regulatory requirements. In January 2013, FHN issued $100 million of Non-Cumulative Perpetual Preferred Stock, Series A. As of December 31, 2017, FTBNA and subsidiaries had outstanding preferred shares of $295.4 million, which are reflected as noncontrolling interest on the Consolidated Statements of Condition. Parent company liquidity is primarily provided by cash flows stemming from dividends and interest payments collected from subsidiaries. These sources of cash represent the primary sources of funds to pay cash dividends to shareholders and principal and interest to debt holders of FHN. The amount paid to the parent company through FTBNA common dividends is managed as part of FHN’s overall cash management process, subject to applicable regulatory restrictions. Certain regulatory restrictions exist regarding the ability of FTBNA to transfer funds to FHN in the form of cash, common dividends, loans, or advances. At any given time, the pertinent portions of those regulatory restrictions allow FTBNA to declare preferred or common dividends without prior regulatory approval in an aggregate amount equal to FTBNA’s retained net income for the two most recent completed years plus the current year to date. For any period, FTBNA’s ‘retained net income’ generally is equal to FTBNA’s regulatory net income reduced by the preferred and common dividends declared by FTBNA. Excess dividends in either of the two most recent completed years may be offset with available retained net income in the two years immediately 54 FIRST HORIZON NATIONAL CORPORATION preceding it. Applying the dividend restrictions imposed under applicable federal rules as outlined above, the Bank’s total amount available for dividends was negative $156.7 million as of December 31, 2017. Consequently, on that date the Bank could not pay common dividends to its sole common stockholder, FHN, or to its preferred shareholders without prior regulatory approval. However, at January 1, 2018, under those dividend restrictions, the Bank could legally declare cash dividends on the Bank’s common or preferred stock of approximately $51.1 million without obtaining regulatory approval. FTBNA applied for and received approval from the OCC to declare and pay common dividends to FHN for $250 million in both 2017 and 2016. FTBNA declared and paid preferred dividends in each quarter of 2017 and 2016, with OCC approval as necessary. Additionally, FTBNA declared preferred dividends in first quarter 2018 payable in April 2018. Payment of a dividend to shareholders of FHN is dependent on several factors which are considered by the Board. These factors include FHN’s current and prospective capital, liquidity, and other needs, applicable regulatory restrictions, and also availability of funds to FHN through a dividend from FTBNA. Additionally, the Federal Reserve and the OCC generally require insured banks and bank holding companies to pay cash dividends only out of current operating earnings. Consequently, the decision of whether FHN will pay future dividends and the amount of dividends will be affected by current operating results. FHN paid a cash dividend of $.09 per common share on January 2, 2018, and in January 2018 the Board approved a $.12 per common share cash dividend payable on April 2, 2018, to shareholders of record on March 9, 2018. FHN paid a cash dividend of $1,550.00 per preferred share on January 10, 2018, and in January 2018 the Board approved a $1,550.00 per preferred share cash dividend payable on April 10, 2018, to shareholders of record on March 23, 2018. CREDIT RATINGS FHN is currently able to fund a majority of the balance sheet through core deposits, which are generally not as sensitive to FHN’s credit ratings as other types of funding. However, maintaining adequate credit ratings on debt issues and preferred stock is critical to liquidity should FHN need to access funding from other sources, including from long-term debt issuances and certain brokered deposits, at an attractive rate. The availability and cost of funds other than core deposits is also dependent upon marketplace perceptions of the financial soundness of FHN, which include such factors as capital levels, asset quality, and reputation. The availability of core deposit funding is stabilized by federal deposit insurance, which can be removed only in extraordinary circumstances, but may also be influenced to some extent by the same factors that affect other funding sources. FHN’s credit ratings are also referenced in various respects in agreements with certain derivative counterparties as discussed in Note 22 – Derivatives.

FIRST HORIZON NATIONAL CORPORATION 55 CASH FLOWS The Consolidated Statements of Cash Flows provide information on cash flows from operating, investing, and financing activities for the years ended December 31, 2017, 2016, and 2015. The level of cash and cash equivalents increased $414.3 million during 2017 and $6.7 million in 2016 compared to a decrease of $40.3 million in 2015. During 2017, cash provided by financing activities was greater than cash used by operating and investing activities, whereas in 2016 and 2015 the cash provided by operating and financing activities was more than cash provided by investing activities. Net cash provided by financing activities was $1.8 billion in 2017 compared to $2.3 billion in 2016. In 2017, FHN had financing cash inflows of $2.1 billion related to an increase in short-term borrowings, primarily FHLB borrowings used to fund loan growth; however, these were somewhat offset by a decrease in deposit balances and an increase in cash dividends relative to 2016. Net cash used by investing activities was $1.3 billion in 2017 as compared to $2.5 billion in 2016. Investing outflows in 2017 were primarily driven by increases in loan balances and interest-bearing cash of $808.4 million and $121.4 million, respectively, as well as $336.6 million of net cash payments associated with the CBF and Coastal acquisitions. Net cash used by operating activities was $17.4 million in 2017 compared to net cash provided by operating activities of $182.7 million in 2016. Operating cash flows in 2017 were negatively impacted by a net increase in loans HFS within the fixed income segment as well as cash outflows of $384.2 million related to fixed income activities, but were favorably impacted by cash-related net income items and a $226.2 million net decrease in operating assets and liabilities. Net cash provided by financing activities was $2.3 billion in 2016 compared to $111.0 million in 2015. In 2016, financing cash inflows were positively affected by a $2.7 billion increase in deposits, due in large part to increases in insured network deposits and commercial customer deposits, but were somewhat offset by $267.5 million in payments of long-term borrowings, which included the maturity of $250 million of subordinated notes. Additionally, share repurchases and dividend payments negatively affected financing cash flows in 2016, offsetting a portion of the increase in cash provided by financing activities. Net cash provided by operating activities was $182.7 million in 2016 compared to $367.0 million in 2015. Operating cash flows in 2016 were favorably driven by cash-related net income items, but were negatively affected by a $165.0 million cash contribution to the qualified pension plan in third quarter and net changes in operating assets and liabilities of $43.7 million. Net cash used by investing activities was $2.5 billion in 2016 compared to $518.4 million in 2015. Investing cash outflows in 2016 were primarily attributable to loan growth within the regional bank, including the purchase of $537.4 million UPB of franchise finance loans in third quarter. Additionally, a $457.2 million increase in interest-bearing cash, as well as net cash outflows related to the purchases of AFS securities and premises and equipment also negatively impacted investing cash flows in 2016. Net cash used by investing activities was $518.4 million in 2015. Cash outflows in 2015 were primarily attributable to loan growth within the regional bank and a $332.2 million net decrease in cash related to the available-for-sale securities portfolio, as purchases were greater than cash inflows from sales and maturities. These cash outflows were somewhat offset by a $1.0 billion decrease in interest-bearing cash which positively affected cash flows from investing activities. Net cash provided by operating activities was $367.0 million in 2015. Operating cash flows in 2015 were favorably driven by cash-related net income items and a $266.7 million net increase in cash related to fixed income activities, but were somewhat offset by cash outflows related to operating assets and liabilities of $118.0 million. Net cash provided by financing activities was $111.0 million in 2015. In 2015 financing cash inflows were favorably impacted by a $1.6 billion increase in deposits, largely the result of an increase in commercial customer deposits and the timing of a new correspondent banking product which resulted in a shift in funding from short-term borrowings. Additionally, proceeds from the issuance of $500.0 million of senior notes in 2015 positively affected financing cash flows. These inflows were partially offset by cash outflows related to long- term debt, including the maturity of $500 million of senior notes and $304 million of subordinated notes, as well as the redemption of $206 million of junior subordinated debt underlying trust preferred securities. Additionally, an $816.3 million decrease in short-term borrowings, due in part to the shift in funding associated with the new product offering in correspondent banking previously mentioned, as well as dividends paid and share repurchases negatively impacted cash from financing activities in 2015. 56 FIRST HORIZON NATIONAL CORPORATION REPURCHASE OBLIGATIONS, OFF-BALANCE SHEET ARRANGEMENTS, AND OTHER CONTRACTUAL OBLIGATIONS Obligations from Legacy Mortgage Businesses 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 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 could no longer 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 then contracted to have its remaining servicing obligations sub-serviced. Since the platform sale FHN has sold substantially all remaining servicing assets and obligations in several transactions. 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 a substantial majority 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 FIRST HORIZON NATIONAL CORPORATION 57 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. A number of those matters have settled or otherwise been resolved. See Note 17 – Contingencies and Other Disclosures for a discussion of certain actions pending against FHN in relation to FH proprietary securitizations. 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 is not significant and 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. As mentioned in Note 17 – Contingencies and Other Disclosures – FHN has received a notice of indemnification claims from its 2011 subservicer, Nationstar Mortgage LLC, currently doing business as “Mr. Cooper.” The notice asserts several categories of indemnity obligations by FHN to Nationstar in connection with mortgage loans under the subservicing arrangement and under the purchase transaction. This matter currently is not in formal litigation, but litigation in the future is possible. 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. On December 31, 2017, the remaining UPB of loans held in FH proprietary securitizations was $3.0 billion, comprised of $2.2 billion of Alt-A loans and $.8 billion of Jumbo loans. 58 FIRST HORIZON NATIONAL CORPORATION Mortgage-Related Glossary Agencies the two GSEs and Ginnie Mae certificates securities sold to investors representing interests in mortgage loan securitizations DOJ U.S. Department of Justice DRA definitive resolution agreement with a GSE Fannie Mae, Fannie, FNMA FH proprietary securitization Federal National Mortgage Association securitization of mortgages sponsored by FHN under its First Horizon brand FHA Federal Housing Administration HELOC home equity line of credit HUD Dept. of Housing and Urban Development LTV MI loan-to-value, a ratio of the loan amount divided by the home value private mortgage insurance, insuring against borrower payment default MSR mortgage servicing rights nonconforming loans loans that did not conform to Agency program requirements other whole loans sold mortgage loans sold to private, non-Agency purchasers FHN’s sale of its national mortgage origination and servicing platforms in 2008 pipeline of mortgage repurchase, make-whole, & certain related claims against FHN Freddie Mac, Freddie, FHLMC Federal Home Loan Mortgage Corporation 2008 platform sale, platform sale, 2008 sale Ginnie Mae, Ginnie, GNMA Government National Mortgage Association pipeline or active pipeline GSEs Fannie Mae and Freddie Mac VA Veterans Administration Active Pipeline FHN accumulates the amount of repurchase requests, make-whole claims, and certain other related claims into the “active pipeline.” The active pipeline includes the amount of claims for loan repurchase, make-whole payments, loans as to which MI has been canceled, and information requests from purchasers of loans originated and sold through FHN’s legacy mortgage banking business. MI was required for certain of the loans sold to GSEs or that were securitized. Although unresolved MI cancellation notices are not formal repurchase requests, FHN includes those loans in the active pipeline. Additionally, FHN is responsible for covering losses for purchasers to the extent there is a shortfall in MI insurance coverage (MI curtailment). Generally, the amount of a loan subject to a repurchase/make-whole claim, or with open MI issues, remains in the active pipeline throughout the resolution process with a claimant. Through June 2016 the active pipeline decreased, due in part to settlements and other resolutions, but also due to significant reductions in inflows. The pipeline is now relatively flat at a much lower level due to a slower pace of inflows and resolutions. On December 31, 2017, the active pipeline was $44.1 million, down from $51.7 million on December 31, 2016. The following table provides the number and unpaid principal amount of loans in the active repurchase request pipeline, including related unresolved MI notices and other requests as of December 31, 2017 and 2016. FIRST HORIZON NATIONAL CORPORATION 59 Table 29 – Active Pipeline (Dollars in thousands) Repurchase/make whole requests: Agencies Non-Agency whole loan-related MI Other requests (a) Total December 31, 2017 December 31, 2016 Number Amount Number Amount 32 118 85 49 284 $ 4,661 17,927 13,843 7,637 $44,068 23 126 147 37 333 $ 4,196 19,214 23,171 5,122 $51,703 (a) Other requests typically include requests for additional information from both GSE and non-GSE purchasers. On December 31, 2017, Agencies accounted for approximately 55 percent of the total active pipeline, inclusive of MI cancellation notices, MI curtailments, and all other claims. MI curtailment requests, the largest portion of the active pipeline, are intended only to cover the shortfall in MI insurance proceeds. As a result, FHN’s loss from MI curtailments as a percentage of UPB generally is significantly lower than that of a repurchase or make-whole claim. At December 31, 2017, the active pipeline contained no loan repurchase or make-whole requests from the FH proprietary securitization trustee related to first lien mortgage loans based on claims related to breaches of representations and warranties related to origination. 60 FIRST HORIZON NATIONAL CORPORATION Repurchase Accrual Methodology Over the past several years FHN’s approach for determining the adequacy of the repurchase and foreclosure reserve has evolved, sometimes substantially, based on changes in information available. Repurchase/make-whole rates vary based on purchaser, vintage, and claim type. For those loans repurchased or covered by a make-whole payment, cumulative average loss severities range between 50 and 60 percent of the UPB. Repurchase Accrual Approach Repurchase/Make-whole and Damages obligations and estimates for probable incurred losses associated with loan populations excluded from the DRAs are significant components of FHN’s remaining repurchase liability as of December 31, 2017. Other components of that liability primarily relate to other whole loans sold, MI rescissions, and loans included in bulk servicing sales effected prior to the DRAs. In determining the loss content of GSE loans subject to repurchase requests excluded from the DRAs (primarily loans included in bulk sales), FHN applies a vintage level estimate of loss to all loans sold to the GSEs that were not included in the settlements and which have not had a prior repurchase resolution. First, pre-payment, default, and claim rate estimates are applied by vintage to estimate the aggregate claims expected but not yet resolved. Historical loss factors for each sale vintage and repurchase rates are then applied to estimate total loss content. Loss content related to other whole loan sales is estimated by applying the historical average repurchase and loss severity rates to the current UPB in the active pipeline to calculate estimated losses attributable to the current pipeline. FHN then uses an internal model to calculate loss content by applying historical average repurchase and loss severity rates to historical average inflows. For purposes of estimating loss content, FHN also considers MI cancellations. When assessing loss content related to loans where MI has been cancelled, FHN applies historical loss factors (including repurchase rates and loss severity ratios) to the total unresolved MI cancellations in the active pipeline, as well as applying these factors to historical average inflows to estimate loss content. Additionally, FHN identifies estimated losses related to MI curtailment requests. Management also evaluates the nature of claims from purchasers and/or servicers of loans sold to determine if qualitative adjustments are appropriate. Repurchase and Foreclosure Liability The repurchase and foreclosure liability is comprised of reserves to cover estimated loss content in the active pipeline, as well as estimated loss content related to certain known claims not currently included in the active pipeline. FHN compares the estimated probable incurred losses determined under the applicable loss estimation approaches described above 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. The following table provides a rollforward of the legacy mortgage repurchase liability during 2017 and 2016: Table 30 – Reserves for Repurchase and Foreclosure Losses (Dollars in thousands) Legacy Mortgage Beginning balance Provision/(provision credit) for repurchase and foreclosure losses (a) Net realized losses 2017 2016 $ 65,309 (22,527) (9,226) $114,947 (32,722) (16,916) Balance on December 31 (a) Year ended December 31, 2017 and 2016 include $20.0 million and $31.4 million, respectively, related to the settlement of certain $ 33,556 $ 65,309 repurchase claims. Other FHN Mortgage Exposures At December 31, 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. FIRST HORIZON NATIONAL CORPORATION 61 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 the sales of MSR from 2008 through 2014, 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; and (iii) FHN has received repurchase, indemnity, and other demands from purchasers or their assignees. At December 31, 2017, FHN’s repurchase and foreclosure liability included certain known exposures from other whole loans sold. Other Contractual Obligations Pension obligations are funded by FHN to provide current and future benefits to participants in FHN’s noncontributory, defined benefit pension plan. On December 31, 2017, the annual measurement date, pension obligations (representing the present value of estimated future benefit payments), including obligations of the unfunded plans, were $840.9 million with $881.2 million of assets (measured at current fair value) in the qualified plan’s trust to fund the qualified plan’s obligations. The discount rate for 2017 of 3.76 percent for the qualified pension plan and 3.59 percent for the nonqualified supplemental executive retirement plan was determined by using a hypothetical AA yield curve represented by a series of annualized individual discount rates from one-half to thirty years. The discount rates for the pension and nonqualified supplemental executive retirement plans are selected based on data specific to FHN’s plans and participant populations. See Note 18 - Pension, Savings, and Other Employee Benefits for additional information. As of December 31, 2017, the plan assets exceeded the projected benefit obligation and the accumulated benefit obligation for the qualified pension plan. 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. No contributions were made to the qualified pension plan in 2017. In December 2017 FHN contributed $5.1 million to pension plans acquired from CBF, resulting in those plans being almost fully funded. Management has assessed the need for future contributions, and does not currently anticipate that FHN will make a contribution to the qualified pension plan in 2018. The nonqualified pension plans and other postretirement benefit plans, excluding the retiree medical plan, are unfunded. Benefit payments under the non-qualified plans were $5.4 million in 2017. FHN anticipates 2018 benefit payments to be $5.7 million. FHN has various other financial obligations which may require future cash payments. The following table sets forth contractual obligations representing required and potential cash outflows as of December 31, 2017. Purchase obligations represent obligations under agreements to purchase goods or services that are enforceable and legally binding on FHN and that specify all significant terms, including fixed or minimum quantities to be purchased; fixed, minimum, or variable price provisions; and the approximate timing of the transaction. In addition, FHN enters into commitments to extend credit to borrowers, including loan commitments, standby letters of credit, and commercial letters of credit. These commitments do not necessarily represent future cash requirements in that these commitments often expire without being drawn upon and are not included in the table. 62 FIRST HORIZON NATIONAL CORPORATION Table 31 – Contractual Obligations (Dollars in thousands) Contractual obligations: Payments due by period (a) Less than 1 year 1 year - < 3 years 3 years - < 5 years After 5 years Total Time deposit maturities (b) (c) Term borrowings (b) (d) Annual rental commitments under noncancelable leases (b) (e) Purchase obligations Total contractual obligations $2,001,083 7,401 $ 767,798 900,000 $538,543 209 $ 15,497 353,866 $3,322,921 1,261,476 29,862 83,879 52,844 58,848 39,015 16,841 59,069 8,893 180,790 168,461 $2,122,225 $1,779,490 $594,608 $437,325 $4,933,648 (a) Excludes a $4.3 million liability for unrecognized tax benefits as the timing of payment cannot be reasonably estimated.

MARKET UNCERTAINTIES AND PROSPECTIVE TRENDS FHN’s future results could be affected both positively and negatively by several known trends. Key among those are FHN’s strategic initiatives, changes in the U.S. economy and outlook, government actions affecting interest rates, and potential changes in federal policies. In addition, legacy matters in the non-strategic segment are likely to continue to impact FHN’s annual results in ways which are both difficult to predict and unrelated to current operations. FHN has prioritized expense discipline to include reducing or controlling certain expenses and investing in revenue- producing activities and critical infrastructure. FHN has actively pursued acquisition opportunities while maintaining a disciplined approach to valuations. FHN remains committed to organic growth through customer retention, key hires, targeted incentives, and other traditional means. Performance by FHN, and the entire U.S. financial services industry, is affected considerably by the overall health of the U.S. economy. The most recent recession ended in 2009. Growth during the economic expansion since 2009 largely has been muted, compared to earlier recoveries, and somewhat inconsistent from one quarter to the next. Though the economic expansion is over 8 years old, currently the U.S. economy does not appear to be weakening or falling back into recession. In fact, during 2017 many signs pointed to economic strengthening. A continuation of the current expansion would support, rather than hinder, future loan and other financial activity growth by our customers. Starting in 2015 through 2017, the Federal Reserve has raised short-term interest rates five times, in each case by 25 basis points, signaling a willingness to continue to raise rates in a measured fashion depending on economic data and trends. If the Fed continues to raise rates, FHN’s net interest margin in the future is likely to continue an improving trend. A steeper yield curve should also bolster activity within FHN’s Fixed Income business. However, if future economic data shows a risk of lower growth or recession, interest rates may stall or even fall, which likely would adversely impact FHN’s net interest margin. Falling and/or moderately volatile interest rates, however, should enhance activity within FHN’s Fixed Income business. Also, if Fed actions cause long-term rates to rise slower than short-term rates, then the yield curve would flatten, which would adversely impact FHN’s net interest margin. FHN cannot predict the timing, resolution and effects of potential new legislation. The potential legislative actions which currently seem the most likely to be impactful to FHN include general regulatory reform and financial regulatory reform, both of which can affect the overall economy and FHN customers as well as FHN directly. Lastly, while FHN has made significant progress in resolving matters from the legacy mortgage business, some matters remain unresolved. The timing or financial impact of resolution of these matters, most of which are in litigation, cannot be predicted with accuracy. Accordingly, the non-strategic segment is expected to occasionally and unexpectedly impact FHN’s overall quarterly results negatively or positively with reserve accruals or releases. Also, although new legacy matters of significance arise at a much slower pace than in years past and some formerly common legal claims no longer can be made due to the passage of time, potential for new legacy matters remains. FIRST HORIZON NATIONAL CORPORATION 63 Foreclosure Practices All lenders are affected by the heightened regulation of servicing, foreclosure, and loss mitigation practices, at both federal and state levels, implemented since 2009. In addition, FHN retains exposure for potential deficiencies in servicing related to its legacy servicing business and subservicing arrangements.

Management performs periodic and systematic detailed reviews of its loan portfolio to identify trends and to assess the overall collectability of the loan portfolio. Accounting standards require that loan losses be recorded when management determines it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. Management believes the accounting estimate related to the ALLL is a “critical accounting estimate” as: (1) changes in it can materially affect the provision for loan losses and net income, (2) it requires management to predict borrowers’ likelihood or capacity to repay, often under uncertain economic conditions, and (3) it requires management to distinguish between losses incurred as of a balance sheet date and losses expected to be incurred in the future. Accordingly, this is a highly subjective process and requires significant judgment since it is often difficult to determine when specific loss events may actually occur. The ALLL is increased by the provision for loan losses and recoveries and is decreased by charged-off loans. Principal loan amounts are charged off against the ALLL in the period in which the loan or any portion of the loan is deemed to be uncollectible. This critical accounting estimate applies to the regional banking, non-strategic, and corporate segments. A management committee comprised of representatives from Risk Management, Finance, Credit, and Treasury performs a quarterly review of the assumptions used in FHN’s ALLL analytical models, makes qualitative assessments of the loan portfolio, and determines if qualitative adjustments should be recommended to the modeled results. On a quarterly basis, as a part of Enterprise Risk reporting and discussion, management addresses credit reserve adequacy and credit losses with the Executive and Risk Committee of FHN’s Board of Directors. FHN believes that the critical assumptions underlying the accounting estimates made by management include: (1) the commercial loan portfolio has been properly risk graded based on information about borrowers in specific industries and specific issues with respect to single borrowers; (2) borrower specific information made available to FHN is current and accurate; (3) the loan portfolio has been segmented properly and individual loans have similar credit risk characteristics and will behave similarly; (4) known significant loss events that have occurred were considered by management at the time of assessing the adequacy of the ALLL; (5) the adjustments for economic conditions utilized in the allowance for loan losses estimate represent actual incurred losses; (6) the period of history used for historical loss factors are most reflective of the current environment; (7) the estimate of the time it takes for a loss event to occur and loss to be recognized (the loss emergence period) is most reflective of the current environment; and (8) the reserve rates, as well as other adjustments estimated by management for current events, trends, and conditions, utilized in the process reflect an estimate of losses that have been incurred as of the date of the financial statements. While management uses the best information available to establish the ALLL, future adjustments to the ALLL and methodology may be necessary if economic or other conditions differ substantially from the assumptions used in making the estimates. Such adjustments to original estimates, as necessary, are made in the period in which these factors and other relevant considerations indicate that loss levels vary from previous estimates. See Note 1 – Summary of Significant Accounting Policies and Note 5 – Allowance for Loan Losses for detail regarding FHN’s processes, models, and methodology for determining the ALLL. REPURCHASE AND FORECLOSURE LIABILITY Repurchase Accrual Methodology FHN has established a liability for loan repurchase, make-whole payments, indemnity, and certain other monetary obligations related to national mortgage loan origination and servicing businesses which FHN sold in 2008. The 64 FIRST HORIZON NATIONAL CORPORATION information, including the definitions of certain terms, contained in “Obligations from Legacy Mortgage Businesses” under “Repurchase Obligations, Off-Balance Sheet Arrangements, and Other Contractual Obligations” above should be reviewed before reading this section. Estimating probable losses associated with FHN’s repurchase obligations for alleged breaches of representations and warranties related to prior Agency and other whole loan sales requires significant management judgment and assumptions. The loss estimation process relies on historical observed trends that may or may not be representative of future actual results. Those trends include observed loss severities, resolution statistics, delinquency trends, and historical average loan sizes. Additionally, the level of repurchase/make-whole request and associated losses are affected by external factors such as GSE review practices and selection criteria (for loans sold to GSEs excluded from the DRAs), housing prices, actions of purchasers and/or servicers of previously sold loans, actions of MI companies, and economic conditions, all of which could change in the future. In making these estimates and assumptions FHN has contemplated, among other things, the DRAs, estimates of FHN’s repurchase or monetary exposure related to loans excluded from the DRAs, and estimates of FHN’s repurchase or monetary exposure related to certain other whole loan sales. Additionally, FHN continues to monitor claims included in the active pipeline, claims from other parties for which loans are not identified, historical repurchase rates, and loss severities. Based on currently available information and experience to date, FHN has evaluated its exposure under these obligations and accordingly had reserved for losses of $34.2 million and $66.0 million as of December 31, 2017 and 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 Statements of Condition. Charges to increase/(decrease) the liability are included within Repurchase and foreclosure provision on the Consolidated Statements of Income. The estimate is based upon currently available information and fact patterns that exist as of the balance sheet date and could be subject to future changes. Changes to any one of these factors could significantly impact the estimate of FHN’s liability. FHN continues to monitor trends in claims activity, loss severities, success rates, GSE review practices, MI cancellations, and the status of other claims in order to assess the adequacy of the repurchase liability. At December 31, 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. GOODWILL AND ASSESSMENT OF IMPAIRMENT FHN’s policy is to assess goodwill for impairment at the reporting unit level on an annual basis or between annual assessments if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Impairment is the condition that exists when the carrying amount of goodwill exceeds its implied fair value. FHN also allocates goodwill to the disposal of portions of reporting units in accordance with applicable accounting standards. FHN performs impairment analysis when these disposal actions indicate that an impairment of goodwill may exist. Reporting units have been defined as the same level as the operating business segments. Companies are permitted to make a qualitative assessment of whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill, when determining whether the quantitative assessment should be performed. If FHN concludes that it is more likely than not that a reporting unit’s fair value is less than its carrying value, or if management elects, the quantitative analysis is performed. In 2017, FHN performed a qualitative analysis for its regional banking and fixed income reporting units and determined that it was more likely than not that the fair values of both reporting units exceed their carrying values. In performing its evaluation, FHN considered both positive and negative factors that could affect the status of the regional banking and fixed income reporting units since the most recent quantitative analysis, which was performed in 2016. The factors included trends in revenues and expenses, changes in financial projections, macroeconomic considerations including interest rates, changes in the carrying values of the reporting units and available market pricing evidence. In 2016, FHN engaged an independent valuation expert to assist in the computation of the fair value estimates of each reporting unit as part of its annual assessment. The 2016 assessment for the regional banking reporting unit utilized three separate methodologies: a discounted cash flow model, a comparison to similar public companies’ trading values, and a comparison to recent acquisition values. A weighted average calculation was performed to determine the estimated fair value of the regional banking reporting unit. A discounted cash flow methodology was FIRST HORIZON NATIONAL CORPORATION 65 utilized in determining the fair value of the fixed income reporting unit. The most recent valuations as of October 1, 2016, indicated no goodwill impairment in either of the reporting units with goodwill. As of the most recent quantitative assessment, the fair values of regional banking and fixed income substantially exceeded their carrying values. Management believes the accounting estimates associated with determining fair value as part of the goodwill impairment test is a “critical accounting estimate” because estimates and assumptions are made about FHN’s future performance and cash flows, as well as other prevailing market factors (e.g., interest rates, economic trends, etc.). FHN’s policy allows management to make the determination of fair value using appropriate valuation methodologies and inputs, including utilization of market observable data and internal cash flow models. If a charge to operations for impairment results, this amount would be reported separately as a component of noninterest expense. This critical accounting estimate applies to the regional banking and fixed income business reporting units. As of December 31, 2017, the corporate and non-strategic reporting units had no associated goodwill. When performed, the quantitative impairment testing process conducted by FHN begins by assigning net assets and goodwill to each reporting unit. FHN then completes “step one” of the impairment test by comparing the fair value of each reporting unit with the value (carrying amount) of its net assets, with goodwill included in the computation of the carrying amount. The carrying value of a reporting unit is based on the amount of allocated equity as determined by FHN’s internal management methodologies. FHN does not maintain a record of equity consistent with GAAP at the reporting unit level. Allocated equity is utilized in certain internal performance measures for segments, including return on tangible common equity. In determining the amount of equity allocated to each reporting unit, FHN utilizes a risk-adjusted methodology that incorporates each reporting unit’s credit, market, interest rate, operational, legal, and compliance risks. Unallocated equity is retained in the corporate reporting unit, which has no goodwill. As of the most recent measurement date unallocated equity primarily related to FHN’s capital deployment initiatives, including potential share buybacks, potential dividend increases, and potential acquisitions. If the fair value of a reporting unit exceeds its carrying amount, goodwill of that reporting unit is not considered impaired, and “step two” of the impairment test is not necessary. If the carrying amount of a reporting unit exceeds its fair value, step two of the impairment test would be performed to determine the amount of impairment. Step two of the impairment test requires a comparison of the carrying amount of the reporting unit’s goodwill to the “implied fair value” of that goodwill. The implied fair value of goodwill is computed by assuming all assets and liabilities of the reporting unit would be adjusted to the current fair value, with the offset as an adjustment to goodwill. This adjusted goodwill balance would be the implied fair value used in step two. An impairment charge would be recognized for the amount by which the carrying amount of goodwill exceeds its implied fair value. In connection with obtaining the independent valuation in 2016, management provided certain data and information that was utilized in the estimation of fair value. This information included budgeted and forecasted earnings of FHN at the reporting unit level. Management believes that this information is a critical assumption underlying the estimate of fair value. Other assumptions critical to the process were also made, including discount rates, interest rate changes, asset and liability growth rates, and other income and expense estimates. While management uses the best information available to estimate future performance for each reporting unit, future adjustments to management’s projections may be necessary if conditions differ substantially from the assumptions used in making the estimates. INCOME TAXES FHN is subject to the income tax laws of the U.S. and the states and jurisdictions in which it operates. FHN accounts for income taxes in accordance with ASC 740, Income Taxes. Significant judgments and estimates are required in the determination of the consolidated income tax expense. FHN income tax expense, deferred tax assets and liabilities, and liabilities for unrecognized tax benefits reflect management’s best estimate of current and future taxes to be paid. Income tax expense consists of both current and deferred taxes. Current income tax expense is an estimate of taxes to be paid or refunded for the current period and includes income tax expense related to uncertain tax positions. A DTA or a DTL is recognized for the tax consequences of temporary differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. Deferred taxes can be affected by 66 FIRST HORIZON NATIONAL CORPORATION changes in tax rates applicable to future years, either as a result of statutory changes or business changes that may change the jurisdictions in which taxes are paid. Additionally, DTAs are subject to a “more likely than not” test to determine whether the full amount of the DTAs should be realized in the financial statements. FHN evaluates the likelihood of realization of the DTA based on both positive and negative evidence available at the time, including (as appropriate) scheduled reversals of DTLs, projected future taxable income, tax planning strategies, and recent financial performance. Realization is dependent on generating sufficient taxable income prior to the expiration of the carryforwards attributable to or generated with respect to the DTA. In projecting future taxable income, FHN incorporates assumptions including the amount of future state and federal pretax operating income, the reversal of temporary differences, and the implementation of feasible and prudent tax planning strategies. These assumptions require significant judgment about the forecasts of future taxable income and are consistent with the plans and estimates used to manage the underlying business. If the “more likely than not” test is not met, a valuation allowance must be established against the DTA. The income tax laws of the jurisdictions in which FHN operate are complex and subject to different interpretations by the taxpayer and the relevant government taxing authorities. In establishing a provision for income tax expense, FHN must make judgments and interpretations about the application of these inherently complex tax laws. Interpretations may be subjected to review during examination by taxing authorities and disputes may arise over the respective tax positions. FHN attempts to resolve disputes that may arise during the tax examination and audit process. However, certain disputes may ultimately be resolved through the federal and state court systems. FHN monitors relevant tax authorities and revises estimates of accrued income taxes on a quarterly basis. Changes in estimates may occur due to changes in income tax laws and their interpretation by the courts and regulatory authorities. Revisions of estimates may also result from income tax planning and from the resolution of income tax controversies. Such revisions in estimates may be material to operating results for any given period. See also Note 15 – Income Taxes for additional information. CONTINGENT LIABILITIES A liability is contingent if the amount or outcome is not presently known, but may become known in the future as a result of the occurrence of some uncertain future event. FHN estimates its contingent liabilities based on management’s estimates about the probability of outcomes and their ability to estimate the range of exposure. Accounting standards require that a liability be recorded if management determines that it is probable that a loss has occurred and the loss can be reasonably estimated. In addition, it must be probable that the loss will be confirmed by some future event. As part of the estimation process, management is required to make assumptions about matters that are by their nature highly uncertain. The assessment of contingent liabilities, including legal contingencies, involves the use of critical estimates, assumptions, and judgments. Management’s estimates are based on their belief that future events will validate the current assumptions regarding the ultimate outcome of these exposures. However, there can be no assurance that future events, such as court decisions or decisions of arbitrators, will not differ from management’s assessments. Whenever practicable, management consults with third-party experts (e.g., attorneys, accountants, claims administrators, etc.) to assist with the gathering and evaluation of information related to contingent liabilities. Based on internally and/or externally prepared evaluations, management makes a determination whether the potential exposure requires accrual in the financial statements. See Note 17 – Contingencies and Other Disclosures for additional information.

First Horizon National Corporation’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Even effective internal controls, no matter how well designed, have inherent limitations such as the possibility of human error or of circumvention or overriding of controls, and consideration of cost in relation to benefit of a control. Moreover, effectiveness must necessarily be considered according to the existing state of the art of internal control. Further, because of changes in conditions, the effectiveness of internal controls may diminish over time. Management assessed the effectiveness of First Horizon National Corporation’s internal control over financial reporting as of December 31, 2017. This assessment was based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on our assessment and those criteria, management believes that First Horizon National Corporation maintained effective internal control over financial reporting as of December 31, 2017. On November 30, 2017, we acquired Capital Bank Financial Corp. (“CBF”) and its subsidiaries, including Capital Bank Corporation, by merger. See Note 2 – Acquisitions and Divestitures of our consolidated financial statements for additional information. CBF represented approximately 20% of our consolidated total assets as of December 31, 2017 and 5% of income before income taxes for the year then ended. As permitted by the Securities and Exchange Commission, management has elected to exclude CBF from its assessment of internal control over financial reporting as of December 31, 2017. First Horizon National Corporation’s independent auditors have issued an attestation report on First Horizon National Corporation’s internal control over financial reporting. That report appears on the following page. 76 FIRST HORIZON NATIONAL CORPORATION Report of Independent Registered Public Accounting Firm To the Shareholders and Board of Directors First Horizon National Corporation: Opinion on Internal Control Over Financial Reporting We have audited First Horizon National Corporation and subsidiaries’ (the “Company”) internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the consolidated statements of condition of the Company as of December 31, 2017 and 2016, and the related consolidated statements of income, comprehensive income, equity, and cash flows for each of the years in the three-year period ended December 31, 2017, and related notes, and our report dated February 28, 2018 expressed an unqualified opinion on those consolidated financial statements. On November 30, 2017, the Company acquired Capital Bank Financial Corp. (“CBF”) and its subsidiaries, including Capital Bank Corporation, by merger. CBF represented approximately 20% of consolidated total assets as of December 31, 2017 and 5% of income before income taxes for the year then ended. As permitted by the Securities and Exchange Commission, management elected to exclude CBF from its assessment of internal control over financial reporting as of December 31, 2017. Our audit of internal control over financial reporting of the Company also excluded an evaluation of the internal control over financial reporting of Capital Bank Financial Corp. Basis for Opinion The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Report of Management on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and Limitations of Internal Control Over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Memphis, Tennessee February, 28, 2018 FIRST HORIZON NATIONAL CORPORATION 77 Report of Independent Registered Public Accounting Firm To the Shareholders and Board of Directors First Horizon National Corporation: Opinion on the Consolidated Financial Statements We have audited the accompanying consolidated statements of condition of First Horizon National Corporation and subsidiaries (the “Company”) as of December 31, 2017 and 2016, the related consolidated statements of income, comprehensive income, equity, and cash flows for each of the years in the three-year period ended December 31, 2017, and the related notes (collectively, the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2017, in conformity with U.S. generally accepted accounting principles. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the Company’s internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 28, 2018 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting. This report includes a paragraph stating that management excluded from its assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2017, Capital Bank Financial Corp.’s (“CBF”) internal control over financial reporting. Our audit of internal control over financial reporting of the Company also excluded an evaluation of the internal control over financial reporting of CBF. Basis for Opinion These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion. We have served as the Company’s auditor since 2002.

FIRST HORIZON NATIONAL CORPORATION 83 Notes to the Consolidated Financial Statements Note 1 (cid:2) Summary of Significant Accounting Policies Basis of Accounting. The consolidated financial statements of First Horizon National Corporation (“FHN”), including its subsidiaries, have been prepared in conformity with accounting principles generally accepted in the United States of America and follow general practices within the industries in which it operates. This preparation requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. These estimates and assumptions are based on information available as of the date of the financial statements and could differ from actual results. Principles of Consolidation and Basis of Presentation. The consolidated financial statements include the accounts of FHN and other entities in which it has a controlling financial interest. Variable Interest Entities (“VIEs”) for which FHN or a subsidiary has been determined to be the primary beneficiary are also consolidated. Affiliates for which FHN is not considered the primary beneficiary and in which FHN does not have a controlling financial interest are accounted for by the equity method. These investments are included in other assets, and FHN’s proportionate share of income or loss is included in noninterest income. All significant intercompany transactions and balances have been eliminated. For purposes of comparability, certain prior period amounts have been reclassified to conform to current year presentation. Business Combinations. FHN accounts for acquisitions meeting the definition of a business combination in accordance with ASC 805, “Business Combinations,” which requires acquired assets and liabilities (other than tax and certain benefit plan balances) to be recorded at fair value. Business combinations are included in the financial statements from the respective dates of acquisition. Acquisition related costs are expensed as incurred. Revenue Recognition. FHN derives a significant portion of its revenues from fee-based services. Noninterest income from transaction-based fees is generally recognized when the transactions are completed. Noninterest income from service-based fees is generally recognized over the period in which FHN provides the service. Deposit Transactions and Cash Management. Deposit transactions and cash management include fees for services related to consumer and commercial deposit products (such as service charges on checking accounts), cash management products and services such as electronic transaction processing (Automated Clearing House and Electronic Data Interchange), account reconciliation services, cash vault services, lockbox processing, and information reporting to large corporate clients. Insurance Commissions. Insurance commissions are derived from the sale of insurance products, including acting as an independent agent to provide life, long-term care, and disability insurance. Trust Services and Investment Management. Trust services and investment management fees include investment management, personal trust, employee benefits, and custodial trust services. Brokerage, Management Fees and Commissions. Brokerage, management fees and commissions include fees for portfolio management, trade commissions, and annuity and mutual fund sales. Statements of Cash Flows. For purposes of these statements, cash and due from banks, federal funds sold, and securities purchased under agreements to resell are considered cash and cash equivalents. Federal funds are usually sold for one-day periods, and securities purchased under agreements to resell are short-term, highly liquid investments. Trading Activities. Securities purchased in connection with underwriting or dealer activities (long positions) are carried at fair market value as trading securities. Gains and losses, both realized and unrealized, on these securities are reflected in fixed income noninterest income. Trading liabilities include securities that FHN has sold to other parties but does not own (short positions). FHN is obligated to purchase securities at a future date to cover the short positions. Assets and liabilities for unsettled trades are recorded on the Consolidated 84 FIRST HORIZON NATIONAL CORPORATION Note 1 (cid:2) Summary of Significant Accounting Policies (continued) Statements of Condition as “Fixed income receivables” or “Fixed income payables.” Retained interests from sales and securitizations of first lien mortgages are recognized at fair value as trading securities with gains and losses, both realized and unrealized, recognized in other income on the Consolidated Statements of Income. Cash receipts and payments are classified in investing activities on the Consolidated Statements of Cash Flows based on the purpose for which such financial assets were retained. Investment Securities. Investment securities are reviewed quarterly for possible other-than-temporary impairment (“OTTI”). The review includes an analysis of the facts and circumstances of each individual investment such as the degree of loss, the length of time the fair value has been below cost, the expectation for that security’s performance, the creditworthiness of the issuer and FHN’s intent and ability to hold the security. Debt securities that may be sold prior to maturity and equity securities are classified as securities available-for-sale (“AFS”) and are carried at fair value. The unrealized gains and losses on securities available-for-sale, including debt securities for which no credit impairment exists, are excluded from earnings and are reported, net of tax, as a component of other comprehensive income within shareholders’ equity and the Statements of Comprehensive Income. Debt securities which management has the intent and ability to hold to maturity (“HTM”) are reported at amortized cost. Interest-only strips that are classified as securities AFS are valued at elected fair value. See Note 24 - Fair Value of Assets and Liabilities for additional information. Realized gains and losses for investment securities are determined by the specific identification method and reported in noninterest income. Declines in value judged to be other-than-temporary based on FHN’s analysis of the facts and circumstances related to an individual investment, including securities that FHN has the intent to sell, are also determined by the specific identification method. For HTM debt securities, OTTI recognized is typically credit-related and is reported in noninterest income. For impaired AFS debt securities that FHN does not intend to sell and will not be required to sell prior to recovery but for which credit losses exist, the OTTI recognized is separated between the total impairment related to credit losses which is reported in noninterest income, and the impairment related to all other factors which is excluded from earnings and reported, net of tax, as a component of other comprehensive income within shareholders’ equity and the Statements of Comprehensive Income. National banks chartered by the federal government are, by law, members of the Federal Reserve System. Each member bank is required to own stock in its regional Federal Reserve Bank ("FRB"). Given this requirement, FRB stock may not be sold, traded, or pledged as collateral for loans. Membership in the Federal Home Loan Bank (“FHLB”) network requires ownership of capital stock. Member banks are entitled to borrow funds from the FHLB and are required to pledge mortgage loans as collateral. Investments in the FHLB are non-transferable and, generally, membership is maintained primarily to provide a source of liquidity as needed. Other equity investments include mutual funds which are recognized at net asset value as well as various cost method investments that are subject to impairment reviews when recovery of the recorded investment is considered uncertain. Securities Purchased Under Agreements to Resell and Securities Sold Under Agreements to Repurchase. FHN enters into short-term securities purchased under agreements to resell transactions which are accounted for as collateralized financings except where FHN does not have an agreement to sell the same or substantially the same securities before maturity at a fixed or determinable price. All of FHN’s securities purchased under agreements to resell are recognized as collateralized financings. Securities delivered under these transactions are delivered to either the dealer custody account at the FRB or to the applicable counterparty. Securities sold under agreements to repurchase are offered to cash management customers as an automated, collateralized investment account. Securities sold under agreements to repurchase are also used by the consumer/commercial bank to obtain favorable borrowing rates on its purchased funds. All of FHN’s securities sold under agreements to repurchase are secured borrowings. Collateral is valued daily and FHN may require counterparties to deposit additional securities or cash as collateral, or FHN may return cash or securities previously pledged by counterparties, or FHN may be required to post additional securities or cash as collateral, based on the contractual requirements for these transactions. FHN’s fixed income business utilizes securities borrowing arrangements as part of its trading operations. Securities borrowing transactions generally require FHN to deposit cash with the securities lender. The amount FIRST HORIZON NATIONAL CORPORATION 85 Note 1 (cid:2) Summary of Significant Accounting Policies (continued) of cash advanced is recorded within Securities purchased under agreements to resell in the Consolidated Statements of Condition. These transactions are not considered purchases and the securities borrowed are not recognized by FHN. FHN does not conduct securities lending transactions. Loans Held-for-Sale. Loans originated or purchased in which management lacks the intent to hold are included in loans held-for-sale in the Consolidated Statements of Condition. FHN has elected the fair value option on a prospective basis for certain mortgage loans held-for-sale, which includes loans originated subsequent to 2007 and repurchased loans that are not governmentally insured. Such loans are carried at fair value, with changes in the fair value recognized in the other income section of the Consolidated Statements of Income. For mortgage loans originated for sale for which the fair value option is elected, loan origination fees are recorded by FHN when earned and related direct loan origination costs are recognized when incurred. See Note 24 - Fair Value of Assets and Liabilities for additional information. FHN accounts for all other loans held-for-sale at the lower of cost or market value (“LOCOM”). Loans. Generally, loans are stated at principal amounts outstanding, net of unearned income. Interest on loans is recognized on an accrual basis at the applicable interest rate on the principal amount outstanding. Loan origination fees and direct costs as well as premiums and discounts are amortized as level yield adjustments over the respective loan terms. Unamortized net fees or costs are recognized upon early repayment of the loans or charge-off. Loan commitment fees are generally deferred and amortized on a straight-line basis over the commitment period. Due to the timing of the merger completion, the loan accounting policies of both FHN and CBF are in the process of being reviewed in detail. Upon completion of such review, conforming adjustments or financial statement reclassification may be determined. Nonaccrual and Past Due Loans. Generally, loans are placed on nonaccrual status if it becomes evident that full collection of principal and interest is at risk, impairment has been recognized as a partial charge-off of principal balance due to insufficient collateral value and past due status, or on a case-by-case basis if FHN continues to receive payments, but there are other borrower-specific issues. • The accrual status policy for commercial troubled debt restructurings (“TDRs”) follows the same internal policies and procedures as other commercial portfolio loans. • Residential real estate secured loans discharged in bankruptcy that have not been reaffirmed by the borrower (“discharged bankruptcies”) are placed on nonaccrual regardless of delinquency status and are reported as TDRs. • Current second lien residential real estate loans that are junior to first liens are placed on nonaccrual status if the first lien is 90 or more days past due, is a bankruptcy, or is a troubled debt restructuring. • Consumer real estate (HELOC and residential real estate installment loans), if not already on nonaccrual per above situations, are placed on nonaccrual if the loan is 30 or more days delinquent at the time of modification and is also determined to be a TDR. • Government guaranteed/insured residential mortgage loans remain on accrual (even if the loan falls into one of the above categories) because the collection of principal and interest is reasonably assured. For commercial and consumer loans within each portfolio segment and class that have been placed on nonaccrual status, accrued but uncollected interest is reversed and charged against interest income when the loan is placed on nonaccrual status. Management may elect to continue the accrual of interest when the estimated net realizable value of collateral is sufficient to recover the principal balance and accrued interest. Interest payments received on nonaccrual loans are normally applied to outstanding principal first. Once all principal has been received, additional interest payments are recognized on a cash basis as interest income. Generally, commercial and consumer loans within each portfolio segment and class that have been placed on nonaccrual status can be returned to accrual status if all principal and interest is current and FHN expects full repayment of the remaining contractual principal and interest. This typically requires that a borrower make 86 FIRST HORIZON NATIONAL CORPORATION Note 1 (cid:2) Summary of Significant Accounting Policies (continued) payments in accordance with the contractual terms for a sustained period of time (generally for a minimum of six months) before being returned to accrual status. For TDRs, FHN may also consider a borrower’s sustained historical repayment performance for a reasonable time prior to the restructuring in assessing whether the borrower can meet the restructured terms, as it may indicate whether the borrower is capable of servicing the level of debt under the modified terms. Residential real estate loans discharged through Chapter 7 bankruptcy and not reaffirmed by the borrower are not returned to accrual status. For current second liens that have been placed on nonaccrual because the first lien is 90 or more days past due or is a TDR or bankruptcy, the second lien may be returned to accrual upon pay-off or cure of the first lien. Charge-offs. For all commercial and consumer loan portfolio segments, all losses of principal are charged to the allowance for loan losses ("ALLL") in the period in which the loan is deemed to be uncollectible. For consumer loans, the timing of a full or partial charge-off generally depends on the loan type and delinquency status. Generally, for the consumer real estate and permanent mortgage portfolio segments, a loan will be either partially or fully charged-off when it becomes 180 days past due. At this time, if the collateral value does not support foreclosure, balances are fully charged-off and other avenues of recovery are pursued. If the collateral value supports foreclosure, the loan is charged-down to net realizable value (collateral value less estimated costs to sell) and is placed on nonaccrual status. For residential real estate loans discharged in Chapter 7 bankruptcy and not reaffirmed by the borrower, the fair value of the collateral position is assessed at the time FHN is made aware of the discharge and the loan is charged down to the net realizable value (collateral value less estimated costs to sell). Within the credit card and other portfolio segment, credit cards and installment loans secured by automobiles are normally charged-off upon reaching 180 days past due while other non-real estate consumer loans are charged-off upon reaching 120 days past due. Impaired Loans. Impaired loans include nonaccrual commercial loans greater than $1 million and modified consumer and commercial loans that have been classified as a TDR and are individually measured for impairment under the guidance of ASC 310. TDRs are always reported as such unless the TDR has exhibited sustained performance, was reported as a TDR over a year-end, and the modified terms were market-based at the time of modification. Purchased Credit-Impaired Loans. ASC 310-30 “Accounting for Certain Loans or Debt Securities Acquired in a Transfer,” provides guidance for acquired loans that have exhibited deterioration of credit quality between origination and the time of acquisition and for which the timely collection of the interest and principal is not reasonably assured (“PCI loans”). PCI loans are initially recorded at fair value which is estimated by discounting expected cash flows at acquisition date. The expected cash flows include all contractually expected amounts (including interest) and incorporate an estimate for future expected credit losses, pre-payment assumptions, and yield requirement for a market participant, among other things. To the extent possible, certain PCI loans were aggregated into pools with composite interest rate and cash flows expected to be collected for the pool. Aggregation into loan pools is based upon common risk characteristics that include similar credit risk or risk ratings, and one or more predominant risk characteristics. Each PCI pool is accounted for as a single unit. Accretable yield is initially established at acquisition and is the excess of cash flows expected at acquisition over the initial investment in the loan and is recognized in interest income over the remaining life of the loan, or pool of loans. Nonaccretable difference is initially established at acquisition and is the difference between the contractually required payments at acquisition and the cash flows expected to be collected at acquisition. FHN estimates expected cash flows for PCI loans on a quarterly basis. Increases in expected cash flows from the last measurement result in reversal of any nonaccretable difference (or allowance for loan losses to the extent any has previously been recorded) with a prospective positive impact on interest income. Decreases to the expected cash flows result in an increase in the allowance for loan losses through provision expense. FHN does not report PCI loans as nonperforming loans due to the accretion of interest income. Additionally, PCI loans that have been pooled and subsequently modified will not be reported as troubled debt restructurings since the pool is the unit of measurement. FIRST HORIZON NATIONAL CORPORATION 87 Note 1 (cid:2) Summary of Significant Accounting Policies (continued) Allowance for Loan Losses. The ALLL is maintained at a level that management determines is sufficient to absorb estimated probable incurred losses in the loan portfolio. The ALLL is increased by the provision for loan losses and loan recoveries and is decreased by loan charge-offs. The ALLL is determined in accordance with ASC 450-20-50 "Contingencies - Accruals for Loss Contingencies" and is composed of reserves for commercial loans evaluated based on pools of credit graded loans and reserves for pools of smaller-balance homogeneous consumer and commercial loans. The reserve factors applied to these pools are an estimate of probable incurred losses based on management’s evaluation of historical net losses from loans with similar characteristics. Additionally, the ALLL includes specific reserves established in accordance with ASC 310-10-35 for loans determined by management to be individually impaired as well as reserves associated with PCI loans. Management uses analytical models to estimate probable incurred losses in the loan portfolio as of the balance sheet date. The models, which are primarily driven by historical losses, are carefully reviewed to identify trends that may not be captured in the historical loss factors used in the models. Management uses qualitative adjustments for those items not yet captured in the models like current events, recent trends in the portfolio, current underwriting guidelines, and local and macroeconomic trends, among other things. The nature of the process by which FHN determines the appropriate ALLL requires the exercise of considerable judgment. See Note 5 – Allowance for Loan Losses for a discussion of FHN’s ALLL methodology and a description of the models utilized in the estimation process for the commercial and consumer loan portfolios. Key components of the estimation process are as follows: (1) commercial loans determined by management to be individually impaired loans are evaluated individually and specific reserves are determined based on the difference between the outstanding loan amount and the estimated net realizable value of the collateral (if collateral dependent), the present value of expected future cash flows or by observable market prices; (2) individual commercial loans not considered to be individually impaired are segmented based on similar credit risk characteristics and evaluated on a pool basis; (3) reserve rates for the commercial segment are calculated based on historical net charge-offs and are subject to adjustment by management to reflect current events, trends, and conditions (including economic considerations and trends); (4) management’s estimate of probable incurred losses reflects the reserve rates applied against the balance of loans in the commercial segment of the loan portfolio; (5) consumer loans are generally segmented based on loan type; (6) reserve amounts for each consumer portfolio segment are calculated using analytical models based on delinquency trends and net loss experience and are subject to adjustment by management to reflect current events, trends, and conditions (including economic considerations and trends); and (7) the reserve amount for each consumer portfolio segment reflects management’s estimate of probable incurred losses in the consumer segment of the loan portfolio. Impairment related to individually impaired loans is measured in accordance with ASC 310-10. For all commercial portfolio segments, commercial TDRs and other individually impaired commercial loans are measured based on the present value of expected future payments discounted at the loan’s effective interest rate (“the DCF method”), observable market prices, or for loans that are solely dependent on the collateral for repayment, the net realizable value (collateral value less estimated costs to sell). Impaired loans also include consumer TDRs. Future adjustments to the ALLL may be necessary if economic or other conditions differ substantially from the assumptions used in making the estimates or, if required by regulators, based upon information at the time of their examinations or upon future regulatory guidance. Such adjustments to original estimates, as necessary, are made in the period in which these factors and other relevant considerations indicate that loss levels vary from previous estimates. Premises and Equipment. Premises and equipment are carried at cost less accumulated depreciation and amortization and include additions that materially extend the useful lives of existing premises and equipment. All other maintenance and repair expenditures are expensed as incurred. Premises and equipment held-for-sale are generally valued at appraised values which reference recent disposition values for similar property types but also consider marketability discounts for vacant properties. The valuations of premises and equipment held-for- sale are reduced by estimated costs to sell. Gains and losses on dispositions are reflected in noninterest income and expense, respectively. 88 FIRST HORIZON NATIONAL CORPORATION Note 1 (cid:2) Summary of Significant Accounting Policies (continued) Depreciation and amortization are computed on the straight-line method over the estimated useful lives of the assets and are recorded as noninterest expense. Leasehold improvements are amortized over the lesser of the lease periods or the estimated useful lives using the straight-line method. Useful lives utilized in determining depreciation for furniture, fixtures and equipment and for buildings are three to fifteen and seven to forty-five years, respectively. Other Real Estate Owned ("OREO"). Real estate acquired by foreclosure or other real estate-owned consists of properties that have been acquired in satisfaction of debt. These properties are carried at the lower of the outstanding loan amount or estimated fair value less estimated costs to sell the real estate. At the time acquired, and in conjunction with the transfer from loans to OREO, there is a charge-off against the ALLL if the estimated fair value less costs to sell is less than the loan’s cost basis. Subsequent declines in fair value and gains or losses on dispositions, if any, are charged to All other expense on the Consolidated Statements of Income. Prior to January 1, 2015, properties acquired by foreclosure in compliance with HUD servicing guidelines are included in “OREO” and are carried at the estimated amount of the underlying government insurance or guarantee. On December 31, 2017, FHN had $3.8 million of these properties. Required developmental costs associated with acquired property under construction are capitalized and included in determining the estimated net realizable value of the property, which is reviewed periodically, and any write- downs are charged against current earnings. Intangible Assets. Intangible assets consist of “Other intangible assets” and “Goodwill.” Other intangible assets represent customer lists and relationships, acquired contracts, covenants not to compete and premium on purchased deposits, which are amortized over their estimated useful lives. Intangible assets related to acquired deposit bases are primarily amortized over 10 years using an accelerated method. Management evaluates whether events or circumstances have occurred that indicate the remaining useful life or carrying value of amortizing intangibles should be revised. Goodwill represents the excess of cost over net assets of acquired businesses less identifiable intangible assets. On an annual basis, FHN assesses goodwill for impairment. Derivative Financial Instruments. FHN accounts for derivative financial instruments in accordance with ASC 815 which requires recognition of all derivative instruments on the balance sheet as either an asset or liability measured at fair value through adjustments to either accumulated other comprehensive income within shareholders’ equity or current earnings. Fair value is defined as the price that would be received to sell a derivative asset or paid to transfer a derivative liability in an orderly transaction between market participants on the transaction date. Fair value is determined using available market information and appropriate valuation methodologies. FHN has elected to present its derivative assets and liabilities gross on the Consolidated Statements of Condition. Amounts of collateral posted or received have not been netted with the related derivatives unless the collateral amounts are considered legal settlements of the related derivative positions. See Note 22 – Derivatives for discussion on netting of derivatives. FHN prepares written hedge documentation, identifying the risk management objective and designating the derivative instrument as a fair value hedge or cash flow hedge as applicable, or as a free-standing derivative instrument entered into as an economic hedge or to meet customers’ needs. All transactions designated as ASC 815 hedges must be assessed at inception and on an ongoing basis as to the effectiveness of the derivative instrument in offsetting changes in fair value or cash flows of the hedged item. For a fair value hedge, changes in the fair value of the derivative instrument and changes in the fair value of the hedged asset or liability attributable to the hedged risk are recognized currently in earnings. For a cash flow hedge, changes in the fair value of the derivative instrument, to the extent that it is effective, are recorded in accumulated other comprehensive income and subsequently reclassified to earnings as the hedged transaction impacts net income. Any ineffective portion of a cash flow hedge is recognized currently in earnings. For free-standing derivative instruments, changes in fair values are recognized currently in earnings. See Note 22 – Derivatives for additional information. Cash flows from derivative contracts are reported as operating activities on the Consolidated Statements of Cash Flows. FIRST HORIZON NATIONAL CORPORATION 89 Note 1 (cid:2) Summary of Significant Accounting Policies (continued) Advertising and Public Relations. Advertising and public relations costs are generally expensed as incurred. Income Taxes. FHN accounts for income taxes using the asset and liability method pursuant to ASC 740, “Income Taxes,” which requires the recognition of deferred tax assets ("DTAs") and liabilities ("DTLs") for the expected future tax consequences of events that have been included in the financial statements. Under this method, FHN’s deferred tax assets and liabilities are determined based on differences between financial statement carrying amounts and the corresponding tax basis of certain assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on DTAs and DTLs is recognized in income in the period that includes the enactment date. Additionally, DTAs are subject to a “more likely than not” test to determine whether the full amount of the DTAs should be recognized in the financial statements. FHN evaluates the likelihood of realization of the DTA based on both positive and negative evidence available at the time, including (as appropriate) scheduled reversals of DTLs, projected future taxable income, tax planning strategies, and recent financial performance. If the “more likely than not” test is not met, a valuation allowance must be established against the DTA. In the event FHN determines that DTAs are realizable in the future in excess of their net recorded amount, FHN would make an adjustment to the valuation allowance, which would reduce the provision for income taxes. FHN records uncertain tax positions in accordance with ASC 740 on the basis of a two-step process in which (1) it is determined whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority is recognized. FHN’s ASC 740 policy is to recognize interest and penalties related to unrecognized tax benefits as a component of income tax expense. Accrued interest and penalties are included within the related tax asset/liability line in the consolidated balance sheet. FHN and its eligible subsidiaries are included in a consolidated federal income tax return. FHN files separate returns for subsidiaries that are not eligible to be included in a consolidated federal income tax return. Based on the laws of the applicable state where it conducts business operations, FHN either files consolidated, combined, or separate returns. The federal tax returns for Capital Bank Financial Corporation for 2010-2012 are under examination by the IRS. With few exceptions, FHN returns are no longer subject to federal or state and local tax examinations by tax authorities for years before 2013. FHN is currently under federal examination for 2013-2015 and is also under examination in several states. Earnings per Share. Earnings per share is computed by dividing net income or loss available to common shareholders by the weighted average number of common shares outstanding for each period. Diluted earnings per share in net income periods is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding adjusted to include the number of additional common shares that would have been outstanding if the potential dilutive common shares resulting from performance shares or units, restricted shares or units, and options granted under FHN’s equity compensation plans and deferred compensation arrangements had been issued. FHN utilizes the treasury stock method in this calculation. Diluted earnings per share does not reflect an adjustment for potentially dilutive shares in periods in which a net loss available to common shareholders exists. Equity Compensation. FHN accounts for its employee stock-based compensation plans using the grant date fair value of an award to determine the expense to be recognized over the life of the award. Stock options are valued using an option-pricing model, such as Black-Scholes. Restricted and performance shares and share units are valued at the stock price on the grant date. Awards with post-vesting transfer restrictions are discounted using models that reflect market considerations for illiquidity. For awards with service vesting criteria, expense is recognized using the straight-line method over the requisite service period (generally the vesting period). Forfeitures are recognized when they occur. For awards vesting based on a performance measure, anticipated performance is projected to determine the number of awards expected to vest, and the corresponding aggregate expense is adjusted to reflect the elapsed portion of the performance period. If a performance period extends beyond the required service term, total expense is adjusted for changes in estimated achievement through the end of the performance period. The fair value of equity awards with cash payout requirements, as well as awards for which fair value cannot be estimated at grant date, is remeasured 90 FIRST HORIZON NATIONAL CORPORATION Note 1 (cid:2) Summary of Significant Accounting Policies (continued) each reporting period through vesting date. Performance awards with pre-grant date achievement criteria are expensed over the period from the start of the performance period through the end of the service vesting term. Awards are amortized using the nonsubstantive vesting methodology which requires that expense associated with awards having only service vesting criteria that continue vesting after retirement be recognized over a period ending no later than an employee’s retirement eligibility date. Repurchase and Foreclosure Provision. The repurchase and foreclosure provision is the charge to earnings necessary to maintain the liability at a level that reflects management’s best estimate of losses associated with the repurchase of loans previously transferred in whole loans sales or securitizations, or make whole requests as of the balance sheet date. See Note 17 - Contingencies and Other Disclosures for discussion related to FHN’s obligations to repurchase such loans. Legal Costs. Generally, legal costs are expensed as incurred. Contingency Accruals. Contingent liabilities arise in the ordinary course of business, including those related to lawsuits, arbitration, mediation, and other forms of litigation. FHN establishes loss contingency liabilities for matters when loss is both probable and reasonably estimable in accordance with ASC 450-20-50 “Contingencies - Accruals for Loss Contingencies”. If loss for a matter is probable and a range of possible loss outcomes is the best estimate available, accounting guidance generally requires a liability to be established at the low end of the range. Expected recoveries from insurance and indemnification arrangements are recognized if they are considered equally as probable and reasonably estimable as the related loss contingency up to the recognized amount of the estimated loss. Gain contingencies and expected recoveries from insurance and indemnification arrangements in excess of the associated recorded estimated losses are recognized when received. Recognized recoveries are recorded as offsets to the related expense in the Consolidated Statements of Income. The favorable resolution of a gain contingency generally results in the recognition of other income in the Consolidated Statements of Income. Contingencies assumed in business combinations are evaluated through the end of the one-year post-closing measurement period. If the acquisition-date fair value of the contingency can be determined during the measurement period, recognition occurs as part of the acquisition-date fair value of the acquired business. If the acquisition-date fair value of the contingency cannot be determined, but loss is considered probable as of the acquisition date and can be reasonably estimated within the measurement period, then the estimated amount is recorded within acquisition accounting. If the requirements for inclusion of the contingency as part of the acquisition are not met, subsequent recognition of the contingency is included in earnings. 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. FHN has elected to recognize forfeitures as they occur. 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). The effects of adopting ASU 2016-09 were not significant. FIRST HORIZON NATIONAL CORPORATION 91 Note 1 (cid:2) Summary of Significant Accounting Policies (continued) 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. In December 2017, the Securities and Exchange Commission issued Staff Accounting Bulletin (“SAB”) No. 118, “Income Tax Accounting Implications of the Tax Cuts and Jobs Act” which provides guidance on the timing of recognition for the effects of the Tax Cuts and Jobs Act of 2017 (the “Tax Act”). Under SAB No. 118, companies are provided a measurement period of up to one year from enactment of the Tax Act to evaluate and record its effects. Companies are expected to make final adjustments when the required information is available. Companies are required to record provisional amounts when sufficient information to make a reasonable estimate is available. SAB No. 118 contains several disclosure requirements regarding a company’s assessment and recording the effects of the Tax Act, including the amounts recorded and the status of estimating potential additional effects. SAB No. 118 was effective immediately upon issuance and FHN has included the required disclosures in Note 15 - Income Taxes. Issued in February 2018, ASU 2018-02, “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income,” provides an election for reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects solely resulting from the Tax Act. The stranded tax effects were created because current accounting requirements indicate that all changes in deferred tax assets and liabilities due to changes in enacted tax rates be recorded through tax provision, even when the deferred tax asset or liability was originally created with an offset to accumulated comprehensive income. For FHN, this includes net deferred tax assets related to net unrealized losses on AFS securities, net actuarial losses for pension and postretirement plans, and the effective portion of cash flow hedging activities. The provisions of ASU 2018-02 do not apply to past or future changes in tax rates. Adoption of ASU 2018-02 is required for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted in any interim period for which financial statements have not yet been issued. FHN elected early adoption as of December 31, 2017 and made a reclassification of $57.5 million from accumulated other comprehensive income to retained earnings. 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. 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 92 FIRST HORIZON NATIONAL CORPORATION Note 1 (cid:2) Summary of Significant Accounting Policies (continued) comparability. FHN has elected to adopt the provisions of the revenue recognition standards through the cumulative effect alternative. Additionally, FHN evaluated the effects of the revenue standards on its recognition and presentation practices and determined that there are no significant effects on the timing of recognition, which results in no cumulative effect adjustment being required. FHN determined that in situations where its broker- dealer operations serve as the lead underwriter, the associated revenues and expenses will be presented gross, on a prospective basis starting in first quarter 2018. The effect on 2018 revenues and expenses will not be significant. 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 has elected to adopt ASU 2017-05 through the cumulative effect approach. FHN has determined that there are no significant effects on the timing of revenue recognition, which results in no cumulative effect adjustment being required. 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 is 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 reclassified all equity investments out of available-for-sale securities, leaving only debt securities within this classification. FHN 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 has applied this election and any future fair value marks for these investments will be recognized through earnings on a prospective basis subsequent to adoption. The requirements of ASU 2016-01 related to assessment of deferred tax assets and disclosure of the fair value of FIRST HORIZON NATIONAL CORPORATION 93 Note 1 (cid:2) Summary of Significant Accounting Policies (continued) financial instruments did not have a significant effect on FHN because its current accounting and disclosure practices conform to the requirements of ASU 2016-01. 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. An alternative cumulative effect transition methodology has been proposed, but not yet issued, which FHN anticipates that it would elect if available. 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. The adoption of ASU 2016-04 did not have a significant effect on FHN’s 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 94 FIRST HORIZON NATIONAL CORPORATION Note 1 (cid:2) Summary of Significant Accounting Policies (continued) 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 continues to evaluate the impact of ASU 2016-13. FHN has met with industry experts, initiated training for key employees associated with the new standard, and defined an initial approach that it is currently testing. Once testing is completed, FHN will begin to develop the formal models and processes that will be required to implement the new standard. 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 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 FHN’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2017 and in Note 18-Pension, Savings, and Other Employee Benefits in in these financial statements. 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 FIRST HORIZON NATIONAL CORPORATION 95 Note 1 (cid:2) Summary of Significant Accounting Policies (continued) guidance does not apply to either 1) debt securities where the prepayment date is not preset or the price is not known in advance or 2) 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. While there is no effect for its current investments, FHN has elected to early adopt the provisions of ASU 2017-08 in first quarter 2018. In August 2017, the FASB issued ASU 2017-12, “Targeted Improvements to Accounting for Hedging Activities,” which revises the financial reporting for hedging relationships through changes to both the designation and measurement requirements for qualifying hedge relationships and the presentation of hedge results. ASU 2017-12 expands permissible risk component hedging strategies, including the designation of a contractually specified interest rate (e.g., a bank’s prime rate) in hedges of cash flows from variable rate financial instruments. Additionally, ASU 2017-12 makes significant revisions to fair value hedging activities, including the ability to measure the fair value changes for a hedged item solely for changes in the benchmark interest rate, permitting partial-term hedges, limiting consideration of prepayment risk for hedged debt instruments solely to the effects of changes in the benchmark interest rate and allowing for certain hedging strategies to be applied to closed portfolios of prepayable debt instruments. ASU 2017-12 also provides elections for the exclusion of certain portions of a hedging instrument’s change in fair value from the assessment of hedge effectiveness. If elected, the fair value changes of these excluded components may be recognized immediately or recorded into other comprehensive income with recycling into earnings using a rational and systematic methodology over the life of the hedging instrument. Under ASU 2017-12 some of the documentation requirements for hedge accounting relationships are relaxed, but the highly effective threshold has been retained. Hedge designation documentation and a prospective qualitative assessment are still required at hedge inception, but the initial quantitative analysis may be delayed until the end of the quarter the hedge is commenced. If certain criteria are met, an election can be made to perform future effectiveness assessments using a purely qualitative methodology. ASU 2017-12 also revises the income statement presentation requirements for hedging activities. For fair value hedges, the entire change in the fair value of the hedging instrument included in the assessment of effectiveness is recorded to the same income statement line item used to present the earnings effect of the hedged item. For cash flow hedges, the entire fair value change of the hedging instrument that is included in the assessment of hedge effectiveness is initially recorded in other comprehensive income and later recycled into earnings as the hedged transaction(s) affect net income with the income statement effects recorded in the same financial statement line item used to present the earnings effect of the hedged item. ASU 2017-12 also makes revisions to the current disclosure requirements for hedging activities to reflect the presentation of hedging results consistent with the changes to income statement classification and to improve the disclosure of the hedging results on the balance sheet. ASU 2017-12 is effective for fiscal years beginning after December 15, 2018 with early adoption permitted in any period after issuance. Adoption for all existing hedging relationships is performed through a cumulative effect adjustment to the applicable balance sheet accounts with an offset to retained earnings as of the beginning of the fiscal year. FHN early adopted the provisions of ASU 2017-12 in the first quarter of 2018. Prospectively, FHN will record components of hedging results for its fair value and cash flow hedges previously recognized in other expense within either interest income or interest expense. Additionally, FHN made cumulative effect adjustments to the hedged items, accumulated other comprehensive income and retained earnings as of the beginning of 2018. The magnitude of the cumulative effect adjustments and prospective effects are insignificant for FHN’s existing hedge relationships. Note 2 (cid:2) Acquisitions and Divestitures On November 30, 2017, FHN completed its acquisition of Capital Bank Financial Corporation (“CBF”) and its subsidiaries, including Capital Bank Corporation for an aggregate of 92,043,171 shares of FHN common stock and $423.6 million in cash in a transaction valued at $2.2 billion. CBF operated 178 branches in North and South Carolina, Tennessee, Florida and Virginia at the time of closing. 96 FIRST HORIZON NATIONAL CORPORATION Note 2 (cid:2) Acquisitions and Divestitures (continued) The following schedule details acquired assets and liabilities and consideration paid, as well as adjustments to record the assets and liabilities at their estimated fair values as of November 30, 2017: (Dollars in thousands) Assets: Cash and cash equivalents Trading securities Loans held-for-sale Securities available-for-sale Securities held-to-maturity Loans Allowance for loan losses CBF Goodwill Other intangible assets Premises and equipment OREO Other assets Total assets acquired Liabilities: Deposits Securities sold under agreements to repurchase Other short-term borrowings Term borrowings Other liabilities Total liabilities assumed Net assets acquired Consideration paid: Equity Cash Total consideration paid Goodwill Capital Bank Financial Corporation Purchase Accounting/ Fair Value Adjustments (unaudited) As Acquired (unaudited) As recorded by FHN $ 205,999 4,758 - 1,017,867 177,549 7,596,049 (45,711) 231,292 24,498 196,298 43,077 617,232 $ - (4,758)(a) $ 134,003 175,526 (177,549) (320,372) 45,711 (231,292) 119,302 37,054 (9,149) 41,320(b) 205,999 - 134,003 1,193,393 - 7,275,677 - - 143,800 233,352 33,928 658,552 $10,068,908 $(190,204) $ 9,878,704 $ 8,141,593 26,664 390,391 119,486 59,995 8,738,129 $ (849) - - 67,683 4,291 71,125 $ 1,330,779 $(261,329) $ 8,140,744 26,664 390,391 187,169 64,286 8,809,254 1,069,450 (1,792,759) (423,592) (2,216,351) $ 1,146,901 (a) Amount represents a conformity adjustment to align with FHN presentation. (b) Amount primarily relates to a net deferred tax asset recorded for the effects of the purchase accounting adjustments. Due to the timing of merger completion in relation to year end, the fact that back office functions (including loan and deposit processing) still have not been integrated, the evaluation of post-merger activity, and the extended information gathering and management review processes required to properly record acquired assets and liabilities, FHN considers its valuations of CBF’s loans, loans held-for-sale, premises and equipment, OREO, other assets, tax receivables and payables, core deposit intangibles, other potential intangibles, time deposits, acquired debt, lease intangibles, other liabilities and acquired contingencies to be provisional as management continues to identify and assess information regarding the nature of these assets and liabilities and reviews the associated valuation assumptions and methodologies. Accordingly, the amounts recorded for current and deferred tax assets and liabilities are also considered provisional as FHN continues to evaluate the nature and extent of permanent and temporary (timing) differences between the book and tax bases of the acquired assets and liabilities assumed. Additionally, the accounting policies of both FHN and CBF are in the process of being reviewed in detail. Upon completion of such review, conforming adjustments or financial statement reclassification may be determined. See Note 17 – Contingencies and Other Disclosures for additional information related to acquired contingencies. FIRST HORIZON NATIONAL CORPORATION 97 Note 2 (cid:2) Acquisitions and Divestitures (continued) In relation to the acquisition, FHN has recorded preliminary goodwill of $1.1 billion, representing the excess of acquisition consideration over the estimated fair value of net assets acquired. All goodwill has been attributed to FHN’s Regional Banking segment (refer to Note 7 – Intangible Assets for additional information). This goodwill is the result of 1) the addition of an experienced workforce, 2) expected synergies to be realized within overlapping banking markets, 3) operational efficiencies to be obtained through integration of back office functions and 4) proportionately lower net operating costs from a larger company scale. $17.0 million of goodwill is expected to be deductible for tax purposes as a result of tax bases carryover resulting from prior CBF acquisitions. FHN’s operating results for 2017 include the operating results of the assets and liabilities acquired from CBF subsequent to the acquisition on November 30, 2017. Following is a description of the methods used to determine the fair values of significant assets and liabilities presented above. Cash and cash equivalents: The carrying amount of these assets is a reasonable estimate of fair value based on the short-term nature of these assets. Securities available-for-sale: Fair values for securities are based on quoted prices where available. If quoted market prices are not available, fair value estimates are based on observable inputs obtained from market transactions in similar securities. Securities held-to-maturity were reclassified to securities available-for-sale based on FHN’s intent at closing. Loans and loans held-for-sale: Fair values for loans were based on a discounted cash flow methodology that considered factors including the type of loan and related collateral, classification status, fixed or variable interest rate, term of loan, amortization status and current discount rates. Loans were aggregated according to similar characteristics when applying various valuation techniques. The discount rate does not include a factor for credit losses as that has been included as a reduction to the estimated cash flows. Loans held-for-sale were classified according to FHN’s intent at closing. Intangible assets: Core deposit intangible ("CDI") represents the value of the relationships with deposit customers. The fair value was based on a discounted cash flow methodology that considered expected customer attrition rates, net maintenance cost of the deposit base, alternate costs of funds, and the interest costs associated with customer deposits. The CDI is being amortized over 10 years using an accelerated methodology based upon the period over which estimated economic benefits are estimated to be received. Lease intangibles are valued using a discounted cash flow methodology which compares the current contractual rental payments to estimated current market rents for the property. Premises and Equipment: Land and buildings held-for-use are valued at appraised values, which reflect considerations of recent disposition values for similar property types with adjustments for characteristics of individual properties. Locations held-for-sale are valued at appraised values which also reference recent disposition values for similar property types but also considers marketability discounts for vacant properties. The valuations of locations held-for-sale are reduced by estimated costs to sell. Other fixed assets are valued using a discounted cash flow methodology which reflects estimates of the future value of the assets to a hypothetical buyer. OREO: OREO properties are valued at estimated fair value less estimated costs to sell the real estate. Estimated fair value is determined using appraised values which includes consideration of recent disposition values for similar property types with adjustments for characteristics of individual properties. Deposits: The fair values used for the demand and savings deposits by definition equal the amount payable on demand at the acquisition date. The fair values for time deposits are estimated using a discounted cash flow calculation using the remaining duration of the accounts and reflects the difference in interest rates currently being offered to the contractual interest rates on such time deposits. Securities sold under agreements to repurchase and Other short-term borrowings: The carrying amount of these liabilities is a reasonable estimate of fair value based on the short-term nature of these liabilities. 98 FIRST HORIZON NATIONAL CORPORATION Note 2 (cid:2) Acquisitions and Divestitures (continued) Term borrowings: The fair values of long-term debt instruments are estimated based on quoted market prices for the instrument if available, or for similar instruments if not available, or by using discounted cash flow analysis, based on estimated current borrowing rates for similar types of instruments and considers whether the debt is currently callable. Estimated discount rates are determined from the perspective of the post-merger combined entity rather than the acquiree and/or original issuers. The following table presents financial information regarding the former CBF operations included in FHN’s Consolidated Statements of Income from the date of acquisition (November 30, 2017) through December 31, 2017. Additionally, the table presents unaudited proforma information as if the acquisition of CBF had occurred on January 1, 2016: (Dollars in thousands) Net interest income Noninterest income Pre-tax income Net income available to common shareholders (a) Actual from acquisition date through December 31, 2017 Unaudited Pro Forma for Year Ended December 31 2017 2016 $31,253 6,192 16,534 NM $1,165,006 563,581 476,911 274,416 $1,033,218 638,493 458,667 293,981 (a) Net income available to common shareholders is not meaningful for actual CBF results from the acquisition date through December 31, 2017 because of the effect of tax reform. The pro forma financial information and explanatory notes have been prepared to illustrate the effects of the merger between FHN and CBF under the acquisition method of accounting. The pro forma financial information is presented for illustrative purposes only and does not necessarily indicate the financial results of the combined companies had the companies actually been combined at the beginning of each period presented, nor does it necessarily indicate the results of operations in future periods or the future financial position of the combined entities. Cost savings and other business synergies related to the acquisition are not reflected in the pro forma amounts. This unaudited pro forma information combines the historical consolidated results of operations of FHN and CBF for the periods presented and gives effect to the following nonrecurring adjustments: Fair value adjustments: Pro forma adjust to net interest income of $34.5 million and $46.5 million for the years ended December 31, 2017 and 2016, respectively, to record estimated amortization of premiums and accretion of discounts on acquired loans, securities, deposits, and term borrowings. CBF accretion/amortization: Pro forma adjustment to net interest income of $24.4 million and $25.9 million for the years ended December 31, 2017 and 2016, respectively, to eliminate CBF amortization of premiums and accretion of discounts and previously acquired loans, securities, and deposits. Amortization of acquired intangibles: Pro forma adjustment to noninterest expense of $15.8 million and $18.0 million for the years ended December 31, 2017 and 2016, respectively, to record estimated amortization on acquired CDI and other lease intangibles. Other adjustments: Pro forma results also include adjustments related to the removal of CBF’s intangible amortization expense, amortization of previously acquired lease intangibles, and FHN’s merger-related costs. Also includes adjustments to depreciation expense to record estimated fair value marks for CBF tangible assets, as well as income-tax effects of pro forma adjustments. FHN incurred $1.0 million of costs associated with the equity issued to CBF shareholders. These costs have been netted against the balance of Capital surplus recognized for the equity portion of the purchase price. All expenses related to the merger and integration with CBF are recorded in FHN’s Corporate segment. Integration activities are expected to be substantially complete within 2018.

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, securitization, and analysis of Small Business Administration (“SBA”) loans, for approximately $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 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. 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. On October 2, 2015, FHN completed its acquisition of TrustAtlantic Financial Corporation (“TrustAtlantic Financial” or “TAF”), and its wholly-owned bank subsidiary TrustAtlantic Bank (“TAB”), for an aggregate of 5,093,657 shares of FHN common stock and $23.9 million in cash in a transaction valued at $96.7 million. Prior to the acquisition TAF and TAB were headquartered in Raleigh, North Carolina, where TAB had five branches located in the communities of Raleigh, Cary and Greenville. TAB merged into FTBNA on October 16, 2015 and the TAB branches became First Tennessee branches upon closing that merger. The acquisition expanded and strengthened FHN’s market share in its Mid-Atlantic region. The following schedule details acquired assets and liabilities and consideration paid, as well as adjustments to record the assets and liabilities at their estimated fair values as of October 2, 2015: (Dollars in thousands) Assets: Cash and cash equivalents Securities available-for-sale Loans, net of unearned income Allowance for loan losses Core deposit intangible TAF Goodwill Premises and equipment, net OREO Deferred tax asset Other assets Total assets acquired Liabilities: Deposits Other liabilities Total liabilities assumed Net assets acquired Consideration paid: Equity consideration Cash Total consideration paid Goodwill TrustAtlantic Financial Corporation Purchase Accounting/ Fair Value Adjustments (unaudited) As Acquired (unaudited) As recorded by FHN $ 18,801 73,822 298,050 (4,639) 84 3,721 2,353 1,018 2,940 10,638 $406,788 $342,788 3,173 345,961 $ 60,827 $ - (10) (16,106) 4,639 1,866 (3,721) 1,214 (95) 4,262 1,135 $ (6,816) $ 1,300 1,407 2,707 $ (9,523) $ 18,801 73,812 281,944 - 1,950 - 3,567 923 7,202 11,773 $399,972 $344,088 4,580 348,668 51,304 (72,791) (23,888) (96,679) $ 45,375 In relation to the acquisition, FHN recorded $45.4 million in goodwill, representing the excess of acquisition consideration over the estimated fair value of net assets acquired (refer to Note 7 – Intangible Assets for additional FIRST HORIZON NATIONAL CORPORATION 101 Note 2 (cid:2) Acquisitions and Divestitures (continued) information). This goodwill is the result of expected operational synergies, expansion in the Mid-Atlantic region and other factors, and only an immaterial amount of goodwill is expected to be deductible for tax purposes. FHN’s operating results for 2017, 2016 and 2015 include the operating results of the acquired assets and assumed liabilities of TAF subsequent to the acquisition on October 2, 2015. In addition to the transactions mentioned above, FHN acquires or divests assets from time to time in transactions that are considered business combinations or divestitures but are not material to FHN individually or in the aggregate. The most recent transaction of that type closed in October 2017, when FTBNA acquired the operations and certain assets of Professional Mortgage Company, Inc. (“PMC”).

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. 104 FIRST HORIZON NATIONAL CORPORATION Note 4 (cid:2) Loans The following table provides the balance of loans, net of unearned income, by portfolio segment as of December 31, 2017 and 2016: (Dollars in thousands) Commercial: Commercial, financial, and industrial Commercial real estate Consumer: Consumer real estate (a) Permanent mortgage Credit card & other Loans, net of unearned income Allowance for loan losses Total net loans December 31 2017 2016 $16,057,273 4,214,695 $12,148,087 2,135,523 6,367,755 399,307 619,899 4,523,752 423,125 359,033 $27,658,929 189,555 $19,589,520 202,068 $27,469,374 $19,387,452 (a) Balances as of December 31, 2017 and 2016, include $24.2 million and $35.9 million of restricted real estate loans, respectively. See Note 21 – 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 (23 percent of total loans). Loans to finance and insurance companies total $2.9 billion (18 percent of the C&I portfolio, or 10 percent of the total loans). FHN had loans to mortgage companies totaling $2.1 billion (13 percent of the C&I segment, or 8 percent of total loans) as of December 31, 2017. As a result, 31 percent of the C&I segment is sensitive to impacts on the financial services industry. Restrictions On December 31, 2017, $4.6 billion of commercial loans were pledged to secure potential discount window borrowings from the Federal Reserve Bank. Additionally, as of December 31, 2017 and 2016, FHN pledged all of its first and second lien mortgages and HELOCs, excluding restricted real estate loans to secure potential borrowings from the FHLB-Cincinnati. Restricted loans secure borrowings associated with consolidated VIEs. See Note 21 – Variable Interest Entities for additional discussion. FIRST HORIZON NATIONAL CORPORATION 105 Note 4 (cid:2) Loans (continued) Acquisition On November 30, 2017, FHN completed its acquisition of CBF. The acquisition included $7.6 billion in unpaid balance of loans with a fair value of $7.4 billion of which $132.8 million is held-for-sale. Generally, the fair value for the acquired loans is estimated using a discounted cash flow analysis with significant unobservable inputs (Level 3) including adjustments for expected credit losses, prepayment speeds, current market rates for similar loans, and an adjustment for investor-required yield given product-type and various risk characteristics. At acquisition, FHN designated certain loans as PCI with the remaining loans accounted for under ASC 310-20, “Nonrefundable Fees and Other Costs”. Of the loans designated as PCI at acquisition, $5.0 million is held-for-sale. For loans accounted for under ASC 310-20, the difference between each loan’s book value and the estimated fair value at the time of the acquisition will be accreted into interest income over its remaining contractual life and the subsequent accounting and reporting will be similar to a loan in FHN’s originated portfolio. The following tables reflect FHN’s contractually required payments receivable, cash flows expected to be collected and the fair value of the acquired loans at the acquisition date of November 30, 2017. These amounts are considered provisional as management continues to identify and assess information regarding the nature of these assets and reviews the associated valuation assumptions and methodologies. (Dollars in thousands) Contractually required payments including interest Less: expected losses and foregone interest Cash flows expected to be collected Fair value of loans acquired (a) (a) Includes $127.8 million of loans held-for-sale.

(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 December 31, 2017, the ALLL related to PCI loans was $3.2 million compared to $.7 million at December 31, 2016. Net charge-offs related to PCI loans during 2017 were $.1 million, compared to $.4 million in 2016. The loan loss provision expense related to PCI loans during 2017 was $2.5 million, compared to a loan loss provision credit of $.5 million during 2016. 106 FIRST HORIZON NATIONAL CORPORATION Note 4 (cid:2) Loans (continued) The following table reflects the outstanding principal balance and carrying amounts of the acquired PCI loans as of December 31, 2017 and 2016: (Dollars in thousands) Commercial, financial and industrial Commercial real estate Consumer real estate Credit card and other Total Impaired Loans December 31, 2017 December 31, 2016 Carrying value Unpaid balance $102,330 30,375 38,176 5,500 $115,296 35,472 42,568 6,351 Carrying value $40,368 4,763 1,172 52 Unpaid balance $41,608 6,514 1,677 64 $176,381 $199,687 $46,355 $49,863 The following tables provide information at December 31, 2017 and 2016, by class related to individually impaired loans and consumer TDRs, regardless of accrual status.

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 108 FIRST HORIZON NATIONAL CORPORATION Note 4 (cid:2) Loans (continued) 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.

Based on the underlying structure of the notes, the best possible internal grade is “13”. (b) The increase in loans year over year is not comparable to the change in allowance year over year as CBF loans are recorded at fair value. 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. The following table reflects the percentage of balances outstanding by average, refreshed FICO scores for the HELOC, real estate installment, and permanent mortgage classes of loans as of December 31, 2017 and 2016: FICO score 740 or greater FICO score 720-739 FICO score 700-719 FICO score 660-699 FICO score 620-659 FICO score less than 620 (a) Total December 31, 2017 R/E Installment Loans Permanent Mortgage 73.1% 8.0 6.4 7.2 2.8 2.5 46.4% 12.8 9.2 14.8 7.3 9.5 HELOC 60.0% 8.7 8.3 11.1 4.9 7.0 HELOC 56.9% 8.8 8.6 13.2 5.6 6.9 December 31, 2016 R/E Installment Loans Permanent Mortgage 70.3% 8.3 6.8 8.4 3.5 2.7 45.0% 9.5 9.2 17.1 9.1 10.1 100.0% 100.0% 100.0% 100.0% 100.0% 100.0% (a) For this group, a majority of the loan balances had FICO scores at the time of the origination that exceeded 620 but have since deteriorated as the loans have seasoned. 110 FIRST HORIZON NATIONAL CORPORATION - - - - Note 4 (cid:2) Loans (continued) Nonaccrual and Past Due Loans The following table reflects accruing and non-accruing loans by class on December 31, 2017: (Dollars in thousands) Current 30-89 Days Past Due 90+ Days Past Due Total Accruing Current 30-89 Days Past Due 90+ Days Past Due Total Non- Accruing Total Loans Accruing Non-Accruing Commercial (C&I): General C&I $13,508,635 $ 8,442 $ Loans to mortgage companies 2,099,961 TRUPS (a) 303,848 - - 95 $13,517,172 $ 1,761 - 2,099,961 - - 303,848 Purchased credit-impaired loans 82,515 3,065 19,559 105,139 $ 7,019 - - - $19,306 $ 28,086 $13,545,258 2,099,961 - - 3,067 3,067 306,915 - - 105,139 Total commercial (C&I) 15,994,959 11,507 19,654 16,026,120 1,761 7,019 22,373 31,153 16,057,273 Commercial real estate: Income CRE Residential CRE Purchased credit-impaired loans 4,126,411 55,655 26,501 Total commercial real estate 4,208,567 856 - 1,828 2,684 - - 4,127,267 56 55,655 2,051 30,380 2,051 4,213,302 56 - - - - 546 791 - 602 791 4,127,869 56,446 - 30,380 1,337 1,393 4,214,695 Consumer real estate: HELOC R/E installment loans Purchased credit-impaired loans 1,738,493 17,828 4,480,953 7,189 9,702 3,573 1,766,023 40,508 4,491,715 14,439 3,626 1,957 8,354 2,603 52,488 18,999 1,818,511 4,510,714 35,356 2,016 1,158 38,530 - - - - 38,530 Total consumer real estate 6,254,802 27,033 14,433 6,296,268 54,947 5,583 10,957 71,487 6,367,755 Permanent mortgage 365,527 3,930 3,460 372,917 13,245 1,052 12,093 26,390 399,307 Credit card & other: Credit card Other Purchased credit-impaired loans Total credit card & other Total loans, net of unearned 193,940 415,070 2,993 612,003 1,371 2,666 1,693 5,730 1,053 103 196,364 417,839 814 5,500 1,970 619,703 - 31 - 31 - - - - - 165 - 165 - 196 196,364 418,035 - 5,500 196 619,899 income $27,435,858 $50,884 $41,568 $27,528,310 $70,040 $13,654 $46,925 $130,619 $27,658,929 (a) TRUPS is presented net of the valuation allowance of $25.5 million.

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 December 31, 2017 and 2016, FHN had $234.4 million and $285.2 million of portfolio loans classified as TDRs, respectively. For TDRs in the loan portfolio, FHN had loan loss reserves of $37.3 million, or 16 percent as of December 31, 2017, and $44.9 million, or 16 percent as of December 31, 2016. Additionally, $63.2 million and $69.3 million of loans held-for-sale as of December 31, 2017 and 2016, respectively, were classified as TDRs.

For commercial loans, ASC 450-20-50 reserves are established using historical net loss factors by grade level, loan product, and business segment. The ALLL for smaller-balance homogeneous consumer loans is determined based on pools of similar loan types that have similar credit risk characteristics. ASC 450-20-50 reserves for the consumer portfolio are determined using segmented roll-rate models that incorporate various factors including historical delinquency trends, experienced loss frequencies, and experienced loss severities. Generally, reserves for consumer loans reflect inherent losses in the portfolio that are expected to be recognized over the following twelve months. The historical net loss factors for both commercial and consumer ASC 450-20-50 reserve models are subject to qualitative adjustments by management to reflect current events, trends, and conditions (including economic considerations and trends), which are not fully captured in the historical net loss factors. The pace of the economic recovery, performance of the housing market, unemployment levels, labor participation rate, the regulatory environment, regulatory guidance, and 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 an 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. Impairment related to individually impaired loans is measured in accordance with ASC 310-10. For all commercial portfolio segments, commercial TDRs and other individually impaired commercial loans are measured based on the present value of expected future payments discounted at the loan’s effective interest rate (“the DCF method”), observable market prices, or for loans that are solely dependent on the collateral for repayment, the net realizable value (collateral value less estimated costs to sell). Impaired loans also include consumer TDRs. Generally, the allowance for TDRs in all consumer portfolio segments is determined by estimating the expected future cash flows using the modified interest rate (if an interest rate concession), incorporating payoff and net charge-off rates specific to the TDRs within the portfolio segment being assessed, and discounted using the pre-modification interest rate. The discount rates of variable rate TDRs are adjusted to reflect changes in the interest rate index to which the rates are tied. The discounted cash flows are then compared to the outstanding principal balance in order to determine required reserves. Residential real estate loans discharged through bankruptcy are collateral- dependent and are charged down to net realizable value (collateral value less estimated costs to sell).

Each of these issuances is held by a wholly owned trust that has issued trust preferred securities to external investors and loaned the funds to FHN, as successor to CBF, as junior subordinated debt. The book value for each issuance represents the purchase accounting fair value as of the closing date less accumulated amortization of the associated discount, as applicable. Through various contractual arrangements FHN assumed a full and unconditional guarantee for each trust’s obligations with respect to the securities. While the maturity dates are typically 30 years from the original issuance date, FHN has the option to redeem each of the junior subordinated debentures at par either immediately or on any future interest payment date, which would trigger redemption of the related trust preferred securities. The junior subordinated debentures are included in the Consolidated Statements of Condition in Term borrowings. A portion of FHN’s junior subordinated notes qualify as Tier 2 capital under the risk-based capital guidelines. Note 11 (cid:2) Preferred Stock FHN Preferred Stock On January 31, 2013, FHN issued 1,000 shares having an aggregate liquidation preference of $100 million of Non-Cumulative Perpetual Preferred Stock, Series A for net proceeds of approximately $96 million. Dividends on the Series A Preferred Stock, if declared, accrue and are payable quarterly, in arrears, at a rate of 6.20% percent per annum. For the issuance, FHN issued depositary shares, each of which represents a 1/4000th fractional ownership interest in a share of FHN’s preferred stock. These securities qualify as Tier 1 capital. Subsidiary Preferred Stock In 2000 FT Real Estate Securities Company, Inc. (“FTRESC”), an indirect subsidiary of FHN, issued 50 shares of 9.50 percent Cumulative Preferred Stock, Class B (“Class B Preferred Shares”), with a liquidation preference of $1.0 million per share; of those, 47 shares were issued to nonaffiliates. As of December 31, 2017, these securities partially qualify as Tier 2 capital and are presented in the Consolidated Statements of Condition as Term borrowings. FTRESC is a real estate investment trust (“REIT”) established for the purpose of acquiring, holding, and managing real estate mortgage assets. Dividends on the Class B Preferred Shares are cumulative and are payable semi-annually. The Class B Preferred Shares are mandatorily redeemable on March 31, 2031, and redeemable at the discretion of FTRESC in the event that the Class B Preferred Shares cannot be accounted for as Tier 2 regulatory capital or there is more than an insubstantial risk that dividends paid with respect to the Class B Preferred Shares will not be fully deductible for tax purposes. At December 31, 2017 the Class B Preferred Shares partially qualified as Tier 2 regulatory capital and the shares will be fully phased out of Tier 2 regulatory capital in 2018. They are not subject to any sinking fund and are not convertible into any other securities of FTRESC, FHN, or any of its subsidiaries. The shares are, however, automatically exchanged at the direction of the Office of the Comptroller of the Currency for preferred stock of FTBNA, having substantially the same terms as the Class B Preferred Shares in the event FTBNA becomes undercapitalized, insolvent, or in danger of becoming undercapitalized. Additionally for all periods presented, subsidiaries have also issued $.6 million in aggregate of Cumulative Perpetual Preferred Stock, which has been recognized as Noncontrolling interest on the Consolidated Statements of FIRST HORIZON NATIONAL CORPORATION 121 Note 11 (cid:2) Preferred Stock (continued) Condition. Other preferred shares are outstanding but are owned by FHN subsidiaries and are eliminated in consolidation. In 2005 FTBNA issued 300,000 shares of Class A Non-Cumulative Perpetual Preferred Stock (“Class A Preferred Stock”) with a liquidation preference of $1,000 per share. Dividends on the Class A Preferred Stock, if declared, accrue and are payable each quarter, in arrears, at a floating rate equal to the greater of the three month LIBOR plus .85 percent or 3.75 percent per annum. These securities qualify fully as Tier 1 capital for FTBNA while for FHN consolidated they qualify partially as Tier 1 capital and partially as Tier 2 capital. On December 31, 2017 and 2016, $294.8 million of Class A Preferred Stock was recognized as Noncontrolling interest on the Consolidated Statements of Condition. Note 12 (cid:2) Regulatory Capital and Restrictions Regulatory Capital. FHN and FTBNA are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on FHN’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, specific capital guidelines that involve quantitative measures of assets, liabilities, and certain derivatives as calculated under regulatory accounting practices must be met. Capital amounts and classification are also subject to qualitative judgment by the regulators such as capital components, asset risk weightings, and other factors. Quantitative measures established by regulation to ensure capital adequacy require FHN and FTBNA to maintain minimum amounts and ratios of Total, Tier 1, and Common Equity Tier 1 capital to risk-weighted assets, and of Tier 1 capital to average assets (“Leverage”). Management believes that, as of December 31, 2017, FHN and FTBNA met all capital adequacy requirements to which they were subject. 122 FIRST HORIZON NATIONAL CORPORATION Note 12 (cid:2) Regulatory Capital and Restrictions (continued) The actual capital amounts and ratios of FHN and FTBNA are presented in the table below.

Under the Federal Reserve Act and Regulation D, FTBNA is required to maintain a certain amount of cash reserves. On December 31, 2017 and 2016, FTBNA’s net required reserves were $278.4 million and $259.2 million, respectively, after the consideration of $255.2 million and $158.9 million in average vault cash. The remaining net reserve requirement for each year was met with Federal Reserve Bank deposits. Vault cash is reflected in Cash and due from banks on the Consolidated Statements of Condition and Federal Reserve Bank deposits are reflected as Interest-bearing cash. Restrictions on dividends. Cash dividends are paid by FHN from its assets, which are mainly provided by dividends from its subsidiaries. Certain regulatory restrictions exist regarding the ability of FTBNA to transfer funds to FHN in the form of cash, dividends, loans, or advances. As of December 31, 2017, FTBNA had undivided profits of $869.1 million, of which none was available for distribution to FHN as dividends without prior regulatory approval until January 1, 2018. At any given time, the pertinent portions of those regulatory restrictions allow FTBNA to declare preferred or common dividends without prior regulatory approval in an amount equal to FTBNA’s retained net income for the two most recent completed years plus the current year to date. For any period, FTBNA’s ‘retained net income’ generally is equal to FTBNA’s regulatory net income reduced by the preferred and common dividends declared by FTBNA. Excess dividends in either of the two most recent completed years may be offset with available retained net income in the two years immediately preceding it. Applying the dividend restrictions FIRST HORIZON NATIONAL CORPORATION 123 Note 12 (cid:2) Regulatory Capital and Restrictions (continued) imposed under applicable federal rules, FTBNA’s total amount available for dividends was negative $156.7 million at December 31, 2017 and positive $51.1 million at January 1, 2018. FTBNA applied for and received approval from the OCC to declare and pay common dividends to the parent company in the amount of in $250.0 million in 2017 and 2016. During 2017 and 2016, FTBNA declared and paid dividends on its preferred stock quarterly, with OCC approval as necessary. Additionally, FTBNA declared preferred dividends in first quarter 2018 payable in April 2018. The payment of cash dividends by FHN and FTBNA may also be affected or limited by other factors, such as the requirement to maintain adequate capital above regulatory guidelines. For example, beginning in 2016, the ability to pay dividends is restricted if capital ratios fall below regulatory minimums plus a prescribed capital conservation buffer. Furthermore, the Federal Reserve and the OCC require insured banks and bank holding companies only to pay dividends out of current operating earnings. Consequently, the decision of whether FHN will pay future dividends and the amount of dividends will be affected by current operating results. Restrictions on intercompany transactions. Under current Federal banking law, FTBNA may not enter into covered transactions with any affiliate including the parent company and certain financial subsidiaries in excess of 10 percent of the bank’s capital stock and surplus, as defined, or $388.2 million, on December 31, 2017. Covered transactions include a loan or extension of credit to an affiliate, a purchase of or an investment in securities issued by an affiliate and the acceptance of securities issued by the affiliate as collateral for any loan or extension of credit. The equity investment, including retained earnings, in certain of a bank’s financial subsidiaries is also treated as a covered transaction. The parent company had covered transactions of $.9 million from FTBNA and the bank’s financial subsidiary, FTN Financial Securities Corp., had a total equity investment from FTBNA of $360.7 million on December 31, 2017. In addition, the aggregate amount of covered transactions with all affiliates, as defined, is limited to 20 percent of the bank’s capital stock and surplus, as defined, or $766.3 million, on December 31, 2017. FTBNA’s total covered transactions with all affiliates including the parent company on December 31, 2017 were $361.7 million. 124 FIRST HORIZON NATIONAL CORPORATION Note 13 (cid:2) Other Income and Other Expense Following is detail of All other income and commissions and All other expense as presented in the Consolidated Statements of Income: (Dollars in thousands) All other income and commissions: Other service charges ATM interchange fees Deferred compensation Electronic banking fees Letter of credit fees Mortgage banking Insurance commissions Gain/(loss) on extinguishment of debt (a) Other Total All other expense: Litigation and regulatory matters Travel and entertainment Other insurance and taxes Customer relations Employee training and dues Supplies Tax credit investments Miscellaneous loan costs OREO Other (b) Total 2017 2016 2015 $ 12,532 12,425 6,322 5,082 4,661 4,649 2,514 (14,329) 11,029 $ 11,731 11,965 3,025 5,477 4,103 10,215 2,981 - 14,734 $ 11,610 11,917 (1,369) 5,840 4,621 3,870 2,627 5,793 15,821 $ 44,885 $ 64,231 $ 60,730 $ 40,517 11,462 9,686 5,750 5,551 4,106 3,468 2,751 1,006 48,891 $ 30,469 10,275 10,891 6,255 5,691 4,434 3,349 2,586 773 41,568 $187,607 9,590 12,941 5,382 5,390 3,827 4,582 2,656 2,104 34,123 $133,188 $116,291 $268,202 (a) Loss on extinguishment of debt for 2017 relates to the repurchase of equity securities previously included in a financing transaction.

The Tax Act reduces the federal statutory tax rate from 35 percent to 21 percent. Although the rate reduction was not effective until January 1, 2018, GAAP required an adjustment in 2017 of deferred tax balances to reflect the new effective tax rate. FHN recorded an $82 million increase in tax expense related to the effects of the Tax Act. This estimate will be adjusted during the measurement period related to the CBF acquisition and as deferred tax items are finalized for the 2017 tax return.

The tax consequence is calculated by applying enacted statutory tax rates, applicable to future years, to these temporary differences. In order to support the recognition of the DTA, FHN’s management must believe that the realization of the DTA is more likely than not. FHN evaluates the likelihood of realization of the DTA based on both positive and negative evidence available at the time, including (as appropriate) scheduled reversals of DTLs, projected future taxable income, tax planning strategies, and recent financial performance. Realization is dependent on generating sufficient taxable income prior to the expiration of the carryforwards attributable to the DTA. In projecting future taxable income, FHN incorporates assumptions including the estimated amount of future state and federal pretax operating income, the reversal of temporary differences, and the implementation of feasible and prudent tax planning strategies. These assumptions require significant judgment about the forecasts of future taxable income and are consistent with the plans and estimates used to manage the underlying business. As of December 31, 2017, FHN’s net DTA was $221.8 million compared with the $199.6 million at December 31, 2016. FHN’s gross DTA (net of a valuation allowance) and gross DTL were $353.2 million and $131.4 million, respectively. FHN’s net DTA increased by $137.7 million on November 30, 2017 upon the merger of CBF into FHN. The provisional estimate of the effects of the Tax Act, discussed in this Note above, includes tax expense related to a decrease in the acquired DTA from CBF by approximately $48.1 million due to the adjustment of the DTA to the lower federal tax rate. As of December 31, 2017, FHN had fully utilized all capital loss carryovers. FHN had a valuation allowance of $40.4 million against its 2012 federal capital loss carryforward as of December 31, 2016. Although realization is not assured, FHN believes that it meets the more-likely-than-not requirement with respect to the net DTA after valuation allowance. 128 FIRST HORIZON NATIONAL CORPORATION Note 15 (cid:2) Income Taxes (continued) Temporary differences which gave rise to deferred tax assets and deferred tax liabilities on December 31, 2017 and 2016 were as follows: (Dollars in thousands) Deferred tax assets: Loss reserves Employee benefits Equity investments Accrued expenses Capital loss carryforwards Credit carryforwards Federal loss carryforwards State loss carryforwards Investment in debt securities (ASC 320) (a) Other Gross deferred tax assets Valuation allowance Deferred tax assets after valuation allowance Deferred tax liabilities: Depreciation and amortization Equity investments Other intangible assets Prepaid expenses Real estate investment trust income Other Gross deferred tax liabilities Net deferred tax assets 2017 2016 $ 91,390 50,404 28,547 16,052 - 64,835 62,010 19,801 8,811 11,512 $ 65,605 83,074 - 16,767 44,469 80,048 175 19,438 10,693 17,340 353,362 (147) 337,609 (40,593) $353,215 $297,016 43,040 - 55,923 9,255 22,576 602 131,396 36,347 12,196 37,596 11,150 - 114 97,403 $221,819 $199,613 Certain previously reported amounts have been reclassified to agree with current presentation. (a) Tax effects of unrealized gains and losses are tracked on a security-by-security basis. The total unrecognized tax benefits (“UTB”) at December 31, 2017 and 2016, was $4.3 million and $4.2 million, respectively. To the extent such unrecognized tax benefits as of December 31, 2017 are subsequently recognized, $1.8 million of tax benefits would impact tax expense and FHN’s effective tax rate in future periods. FHN is currently in audit in several jurisdictions. It is reasonably possible that the UTB related to state exposures could decrease by $.5 million during 2018 if audits are completed and settled and if the applicable statutes of limitations expire as scheduled. FHN recognizes interest accrued and penalties related to UTB within income tax expense. FHN had approximately $.4 million and $.3 million accrued for the payment of interest as of December 31, 2017 and 2016, respectively. The total amount of interest and penalties recognized in the Consolidated Statements of Income during 2017 and 2016 was an expense of $.1 million and $.2 million, respectively.

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 businesses. Certain matters of that sort are pending at this time, and FHN is cooperating in those matters. Pending and threatened litigation matters sometimes are settled by the parties, and sometimes pending matters are resolved in court or before an arbitrator. 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 130 FIRST HORIZON NATIONAL CORPORATION Note 17 (cid:2) Contingencies and Other Disclosures (continued) 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, except for some matters that are reported as having been substantially settled or otherwise substantially resolved, FHN’s “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; (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 December 31, 2017, the aggregate amount of liabilities established for all such loss contingency matters was $41.6 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 December 31, 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 $28 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 FTBNA, as indirect successor to CommunityOne Bank (“C1”) through FTBNA’s merger with CBF in 2017, is defending a consolidated lawsuit brought by approximately 34 alleged victims of a fraudulent scheme known as “Black Diamond.” The action is pending in the U.S. District Court for the Western District of North Carolina (Civ. Act. No. 3:15-cv-00403-RJC-DSC). The Black Diamond scheme ended in 2009 with the arrest of its principal. The Black Diamond business entity had a depositary account with C1. The plaintiffs claim that the Black Diamond account at C1 had the status of a “fiduciary account” under state law, and that C1 breached fiduciary duties owed to plaintiffs (because of that status) by not discovering the fraudulent scheme. Plaintiffs demand restitution of money lost in the scheme plus punitive damages and attorneys’ fees. The current RPL estimate for this matter is subject to significant uncertainties regarding: whether the depositary account at issue will be determined to have been a fiduciary account; the availability and scope of other significantly dispositive defenses; the dollar amounts claimed; and the potential remedies that might be available or awarded. FHN, along with multiple co-defendants, is defending lawsuits brought by investors which claim that offering documents under which certificates relating to First Horizon branded securitizations were sold to them were FIRST HORIZON NATIONAL CORPORATION 131 Note 17 (cid:2) Contingencies and Other Disclosures (continued) 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 liability and RPL estimates for this matter are subject to significant uncertainties regarding: the dollar amounts claimed; the potential remedies that might be available or awarded; the outcome of any settlement discussions that may occur; 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 involving FH proprietary securitizations 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. In late October, 2017, FHN received a notice of indemnification claims from Nationstar Mortgage LLC, currently doing business as “Mr. Cooper.” Nationstar was the purchaser of FHN’s mortgage servicing obligations and assets in 2013 and 2014 and, starting in 2011, FHN’s subservicer. The notice asserts several categories of indemnity obligations by FHN to Nationstar in connection with mortgage loans under the subservicing arrangement and under the purchase transaction. This matter currently is not in formal litigation, but litigation in the future is possible. FHN is unable to estimate an RPL range for this matter due to significant uncertainties regarding: the exact nature of each of Nationstar’s claims and its position in respect of each; the number of, and the facts underlying, the claimed instances of indemnifiable events; the applicability of FHN’s contractual indemnity covenants to those facts and events; and, in those cases where the facts and events might support an indemnity claim, whether any legal defenses, counterclaims, other counter-positions, or third-party claims might eliminate or reduce claims against FHN or their impact on FHN. 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.” 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 132 FIRST HORIZON NATIONAL CORPORATION Note 17 (cid:2) Contingencies and Other Disclosures (continued) 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. FIRST HORIZON NATIONAL CORPORATION 133 Note 17 (cid:2) Contingencies and Other Disclosures (continued) 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 a substantial majority 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. 134 FIRST HORIZON NATIONAL CORPORATION Note 17 (cid:2) Contingencies and Other Disclosures (continued) 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. 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 $34.2 million and $66.0 million as of December 31, 2017 and 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 Statements of Condition. Charges/expense reversals to increase/decrease the liability are included within Repurchase and foreclosure provision/(provision credit) on the Consolidated Statements of Income. The estimates are based upon currently available information and fact patterns that exist as of each balance sheet date and 136 FIRST HORIZON NATIONAL CORPORATION Note 17 (cid:2) Contingencies and Other Disclosures (continued) 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 At December 31, 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, and no such claims had been made. 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; and (iii) FHN has received repurchase, indemnity, and other demands from purchasers or their assignees. At December 31, 2017, FHN’s repurchase and foreclosure liability considered certain known exposures from other whole loans sold. 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 December 31, 2017 and 2016, the derivative liabilities were $5.6 million and $6.2 million, respectively. FIRST HORIZON NATIONAL CORPORATION 137 Note 17 (cid:2) Contingencies and Other Disclosures (continued) 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 holds approximately 1.0 million Visa Class B shares. FHN’s Visa shares are not considered to be marketable and therefore are included in the Consolidated Statements of Condition at their historical cost of $0. As of December 31, 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 December 31, 2017, assuming conversion into Class A shares at the current conversion ratio, FHN’s Visa holdings would have had a value of approximately $197 million. Recognition of market value in the future with that conversion ratio 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. The extent of FHN’s obligations under these agreements depends upon the occurrence of future events; therefore, it is not possible to estimate a maximum potential amount of payouts that could be required by such agreements. Note 18 (cid:2) 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 2017. Management does not currently anticipate that FHN will make a contribution to the qualified pension plan in 2018. FHN assumed two additional qualified pension plans in conjunction with the CBF acquisition. FHN conformed the actuarial assumptions used in measuring the acquired plans to those used for its qualified plan in the purchase accounting valuation. Both legacy CBF plans are frozen. At the closing of FHN’s merger with CBF, those plans had an aggregate benefit obligation of $18.5 million and aggregate plan assets of $13.2 million. FHN contributed $5.1 million to these plans in December 2017. As of December 31, 2017, the aggregate benefit obligation for the plans was $18.7 million and aggregate plan assets were $18.6 million. Benefit payments, expense and actuarial gains/losses related to these plans were insignificant for 2017. After the contribution, FHN altered the investment strategy for the plans to re-allocate plan assets into fixed income investments (primarily Level 1 mutual funds) with durations similar to those for the projected benefit obligation. Additional funding amounts to these plans are dependent upon the potential settlement of the plans. Due to the insignificant financial statement impact, these two plans are not included in the disclosures that follow. 138 FIRST HORIZON NATIONAL CORPORATION Note 18 (cid:2) Pension, Savings, and Other Employee Benefits (continued) 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 $5.4 million for 2017. FHN anticipates making benefit payments under the non-qualified plans of $5.7 million in 2018. Savings plan. FHN provides all qualifying full-time employees with the opportunity to participate in FHN’s tax qualified 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 election. 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. FHN also provides “flexible dollars” to assist employees with the cost of annual benefits and/or allow the employee to contribute to his or her qualified savings plan account. These “flexible dollars” are pre-tax contributions and are based upon the employees’ years of service and qualified compensation. Contributions made by FHN through the flexible benefits plan and the company matches were $23.0 million for 2017, $21.6 million for 2016, and $20.8 million for 2015. 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. Actuarial assumptions. FHN’s process for developing the long-term expected rate of return of pension plan assets is based on capital market exposure as the source of investment portfolio returns. Capital market exposure refers to the plan’s broad allocation of its assets to asset classes, such as large cap equity and fixed income. FHN also considers expectations for inflation, real interest rates, and various risk premiums based primarily on the historical risk premium for each asset class. The expected return is based upon a thirty-year time horizon. In conjunction with the contribution made in 2016, the asset allocation strategy for the qualified pension plan was adjusted through the sale of all equity investments with investment of the proceeds, in addition to the contribution, into fixed income instruments that more closely matched the estimated duration of payment obligations. Consequently, FHN selected a 4.20 percent assumption for 2018 for the qualified defined benefit pension plan and a 2.15 percent assumption for postretirement medical plan assets dedicated to employees who retired prior to January 1, 1993. FHN selected a 5.95 percent assumption for 2018 for postretirement medical plan assets dedicated to employees who retired after January 1, 1993. The discount rates for the three years ended 2017 for pension and other benefits were determined by using a hypothetical AA yield curve represented by a series of annualized individual discount rates from one-half to thirty years. The discount rates are selected based upon data specific to FHN’s plans and employee population. The bonds used to create the hypothetical yield curve were subjected to several requirements to ensure that the resulting rates were representative of the bonds that would be selected by management to fulfill the company’s funding obligations. In addition to the AA rating, only non-callable bonds were included. Each bond issue was required to have at least $300 million ($250 million in 2016 and 2015) par outstanding so that each issue was sufficiently marketable. Finally, bonds more than two standard deviations from the average yield were removed. When selecting the discount rate, FHN matches the duration of high quality bonds with the duration of the obligations of the plan as of the measurement date. For all years presented, the measurement date of the benefit obligations and net periodic benefit costs was December 31. FIRST HORIZON NATIONAL CORPORATION 139 Note 18 (cid:2) Pension, Savings, and Other Employee Benefits (continued) The actuarial assumptions used in the defined benefit pension plans and other employee benefit plans were as follows: Benefit Obligations Net Periodic Benefit Cost 2017 2016 2015 2017 2016 2015 3.76% 3.59% 3.19% 4.39% 4.07% 3.39% 4.68% 4.33% 3.57% 4.37% 4.07% 3.39% 4.69% 4.34% 3.57% 4.30% 4.00% 3.35% 3.37% - 3.87% 3.67% - 4.57% 3.76% - 4.87% 3.68% - 4.57% 3.84% - 4.87% 3.45% - 4.45% Discount rate Qualified pension Nonqualified pension Other nonqualified pension Postretirement benefits Expected long-term rate of return Qualified pension/ postretirement benefits 4.20% 4.50% 6.00% 4.50% 6.00% 5.85% Postretirement benefit (retirees post January 1, 1993) Postretirement benefit (retirees prior to January 1, 1993) 5.95% 6.00% 6.15% 6.00% 6.15% 6.35% 2.15% 2.15% 2.10% 2.15% 2.10% 2.30% The rate of compensation increase previously had a significant effect on the actuarial assumptions used for the defined benefit pension plan. However, since the benefits in the pension plan are frozen, the rate of compensation increase has no effect upon qualified pension benefits. The health care cost trend rate assumption previously had a significant effect on the amounts reported. However, given the change to a defined contribution subsidy model for postretirement medical insurance benefits, a one- percentage-point change in assumed health care cost trend rates would have no impact on the reported service and interest cost components or the postretirement benefit obligation at the end of the plan year since the annual rate of increase in health care costs was no longer included in the actuarial assumptions for that plan for the 2017, 2016 and 2015 measurements. The components of net periodic benefit cost for the plan years 2017, 2016 and 2015 are as follows: (Dollars in thousands) Components of net periodic benefit cost Service cost Interest cost Expected return on plan assets Amortization of unrecognized: Prior service cost/(credit) Actuarial (gain)/loss Net periodic benefit cost ASC 715 curtailment (income) (a) ASC 715 settlement expense Total periodic benefit costs Total Pension Benefits Other Benefits 2017 2016 2015 2017 2016 2015 $ 37 29,380 (36,015) $ 39 31,216 (39,123) $ 40 36,424 (37,516) $ 107 1,305 (947) $ 110 1,292 (913) $ 146 1,413 (956) 52 9,521 2,975 - 43 196 8,141 333 10,103 95 (567) 170 (810) (830) (1,014) 469 9,384 (7) (151) (1,241) - - - - - - - - (8,283) - $ 3,018 $ 469 $ 9,384 $ (7) $ (151) $(9,524) (a) In 2015, an announced revision to the retiree medical plan triggered curtailment accounting. In accordance with its practice, FHN performed a remeasurement of the plan in conjunction with the curtailment and realized a curtailment gain. The long-term expected rate of return is applied to the market-related value of plan assets in determining the expected return on plan assets. FHN determines the market-related value of plan assets using a calculated value that recognizes changes in the fair value of plan assets over five years, as permitted by GAAP. 140 FIRST HORIZON NATIONAL CORPORATION Note 18 (cid:2) Pension, Savings, and Other Employee Benefits (continued) In 2016, FHN changed its methodology for the calculation of interest cost for its applicable employee benefit plans. Prior to 2016 FHN utilized a weighted average discount rate to determine interest cost, which is the same discount rate used to calculate the projected benefit obligations. Starting in 2016, FHN adopted a spot rate approach which applies duration-specific rates from the full yield curve to estimated future benefit payments for the determination of interest cost. This change in accounting estimate reduced interest cost across all plans by $5.8 million in 2016. The following tables set forth the plans’ benefit obligations and plan assets for 2017 and 2016: (Dollars in thousands) Change in benefit obligation Benefit obligation, beginning of year Service cost Interest cost Actuarial (gain)/loss Actual benefits paid (a) Benefit obligation, end of year Change in plan assets Fair value of plan assets, beginning of year Actual return on plan assets Employer contributions Actual benefits paid – settlement payments Actual benefits paid – other payments Total Pension Benefits Other Benefits 2017 2016 2017 2016 $804,542 37 29,380 63,876 (56,951) $816,529 39 31,216 12,733 (55,975) $ 35,403 107 1,305 3,733 (986) $ 33,166 110 1,292 2,110 (1,275) $840,884 $804,542 $ 39,562 $ 35,403 $778,872 84,534 4,789 - (56,951) $638,169 27,448 169,230 - (55,975) $ 16,717 2,458 564 (986) - $ 16,128 991 873 (1,275) - Fair value of plan assets, end of year $811,244 $778,872 $ 18,753 $ 16,717 Funded status of the plans $ (29,640) $ (25,670) $(20,809) $(18,686) Amounts recognized in the Statements of Condition Other assets Other liabilities $ 11,238 (40,878) $ 18,104 (43,774) $ 15,254 (36,063) $ 13,050 (31,736) Net asset/(liability) at end of year $ (29,640) $ (25,670) $(20,809) $(18,686) (a) 2017 and 2016 amounts are higher than historical trends due to the settlements of certain terminated, vested participants in the qualified pension plan that occurred during these years. The qualified pension plan was overfunded as of December 31, 2017 by $11.2 million. The nonqualified pension plans were underfunded as of December 31, 2017 by $40.9 million. Because of the pension freeze as of the end of 2012, the pension benefit obligation and the accumulated benefit obligation are the same as of December 31, 2017 and 2016. The qualified pension plan was overfunded as of December 31, 2016 by $18.1 million. Unrecognized actuarial gains and losses and unrecognized prior service costs and credits are recognized as a component of accumulated other comprehensive income. Balances reflected in accumulated other comprehensive income on a pre-tax basis for the years ended December 31, 2017 and 2016 consist of: (Dollars in thousands) Amounts recognized in accumulated other comprehensive income Prior service cost/(credit) Net actuarial (gain)/loss Total Total Pension Benefits Other Benefits 2017 2016 2017 2016 $ - 385,517 $ 52 379,724 $ - (5,093) $ 95 (8,076) $385,517 $379,776 $(5,093) $(7,981) FIRST HORIZON NATIONAL CORPORATION 141 Note 18 (cid:2) Pension, Savings, and Other Employee Benefits (continued) The pre-tax amounts recognized in other comprehensive income during 2017 and 2016 were as follows: (Dollars in thousands) Changes in plan assets and benefit obligation recognized in other comprehensive income Net actuarial (gain)/loss arising during measurement period Items amortized during the measurement period: Prior service credit/(cost) Net actuarial gain/(loss) Total Pension Benefits Other Benefits 2017 2016 2017 2016 $15,357 $24,408 $2,222 $2,032 (52) (9,521) (196) (8,141) (95) 567 (170) 810 Total recognized in other comprehensive income $ 5,784 $16,071 $2,694 $2,672 FHN utilizes the minimum amortization method in determining the amount of actuarial gains or losses to include in plan expense. Under this approach, the net deferred actuarial gain or loss that exceeds a threshold is amortized over the average remaining service period of active plan participants. The threshold is measured as the greater of: 10 percent of a plan’s projected benefit obligation as of the beginning of the year or 10 percent of the market related value of plan assets as of the beginning of the year. FHN amortizes actuarial gains and losses using the estimated average remaining life expectancy of the remaining participants since all participants are considered inactive due to the freeze. For pension plans, the estimated actuarial loss that would be amortized from AOCI into net periodic benefit cost in 2018 is $11.8 million. For other postretirement plans, the estimated actuarial loss to be amortized from AOCI into net periodic benefit in 2018 is $21.6 million. FHN does not expect any defined benefit pension plan’s and other employee benefit plan’s assets to be returned to FHN in 2018.

FHN’s overall investment goal is to create, over the life of the pension plan and retiree medical plan, an adequate pool of sufficiently liquid assets to support the qualified pension benefit obligations to participants, retirees, and beneficiaries, as well as to partially support the medical obligations to retirees and beneficiaries. Thus, the qualified pension plan and retiree medical plan seek to achieve a high level of investment return consistent with a prudent level of portfolio risk. Prior to the contribution in third quarter 2016, FHN had adopted an investment strategy that reduced equities and increased long duration fixed income allocations over time with the intention of reducing volatility of funded status and pension costs. Plan assets were shifted from equities to fixed income securities when certain funded status thresholds were met. Subsequent to the 2016 contribution, qualified pension plan assets primarily consist of fixed income securities which include U.S. treasuries, corporate bonds of companies from diversified industries, municipal bonds, and foreign bonds. Fixed income investments generally have long durations consistent with the estimated pension liabilities of FHN. This duration-matching strategy is intended to hedge substantially all of the plan’s risk associated with future benefit payments. Retiree medical funds are kept in short-term investments, 142 FIRST HORIZON NATIONAL CORPORATION Note 18 (cid:2) Pension, Savings, and Other Employee Benefits (continued) primarily money market funds and mutual funds. On December 31, 2017 and 2016, FHN did not have any significant concentrations of risk within the plan assets related to the pension plan or the retiree medical plan. The fair value of FHN’s pension plan assets at December 31, 2017 and 2016, by asset category classified using the Fair Value measurement hierarchy is shown in the table below.

The Pension and Savings Investment Committees, comprised of senior managers within the organization, meet regularly to review asset performance and potential portfolio revisions. With the change in asset allocation in 2016, adjustments to the qualified pension plan asset allocation have primarily reflected changes in anticipated liquidity needs for plan benefits.

Most awards outstanding at year end were granted under the ECP, though older stock options and certain deferred stock units remain outstanding under several plans which no longer are active. The ECP authorizes a broad range of award types, including restricted shares, stock units, and stock options. Stock units may be paid in shares or cash, depending upon the terms of the award. The ECP also authorizes the grant of stock appreciation rights, though no such grants have been made. Unvested awards have service and/or performance conditions which must be met in order for the shares to vest. Awards generally have service-vesting conditions, meaning that the employee must remain employed by FHN for certain periods in order for the award to vest. Some outstanding awards also have performance conditions, and two outstanding awards have performance conditions associated with FHN’s stock price. FHN operates the ECP by establishing award programs, each of which is intended to cover a specific need. Programs are created, changed, or terminated as needs change. On December 31, 2017, there were 10,233,661 shares available for new awards under the ECP. The ECP imposes a separate limit on full-value (non-option) awards which is included within the overall limit; at December 31, 2017 there were 7,927,593 shares available to be granted as full-value awards. Service condition full-value awards. Awards may be granted with service conditions only. In recent years, programs using these awards have included annual programs for executives and selected management employees, a mandatory deferral program for executives tied to annual bonuses earned, other mandatory or elective deferral programs, various retention programs, and special hiring-incentive situations. Details of the awards vary by program, but most are settled in shares at vesting rather than cash, and vesting rarely begins earlier than the first anniversary of grant and rarely extends beyond the fourth anniversary of grant. Annual programs tend to use multiple annual vesting dates while retention programs tend to use a single vesting date, but there are exceptions. Performance condition awards. Under FHN’s long-term incentive and corporate performance programs, performance stock units (“PSUs”) (executives) and cash units (selected management employees) are granted annually and vest only if predetermined performance measures are met. The measures are changed each year based on goals and circumstances prevailing at the time of grant. In recent years the performance periods have been three years, with service-vesting near the third anniversary of the grant. PSUs granted after 2014 also have a two-year post-vest holding period. Recent annual performance awards require pro-rated forfeiture for performance falling between a threshold level and a maximum, but all-or-nothing awards have also been granted. Performance awards sometimes are used to provide a narrow, targeted incentive to a single person or small group; two such awards which include a market performance condition to FHN’s Chief Executive Officer (“CEO”) are discussed in the next paragraph. Of the annual program awards paid during 2017 or outstanding on December 31, 2017: performance conditions related to the 2014 units were met at the 112.5 percent payout level and were paid in 2017; the three-year performance period of the 2015 units has ended but performance is measured relative to peers and has not yet been determined; and, the three-year performance periods for the 2016 and 2017 units have not ended. Market condition awards. In 2016 and 2012, FHN made special grants of performance stock units to FHN’s CEO which will vest at the end of a performance period of seven years and five years, respectively. The awards have no provision for pro-rated payment based on partial performance. The 2016 award’s performance goal is based on achievement of a specific level of total shareholder return during the performance period. The 2012 award’s two alternative performance goals are: FHN’s common stock price achieves and maintains a certain level for a certain period of time; or FHN’s total shareholder return during the entire period achieves a certain level. Director awards. Non-employee directors receive cash and annual grants of service-conditioned stock units under a program approved by the board of directors. Director stock units are settled in shares at vesting in the year following the year of grant. In 2017 and 2016 each director received $65,000 or prorated equivalent of stock units, representing a portion of their annual retainer. Prior to 2005 directors could elect to defer cash compensation in the form of discount-priced stock options, some of which remain outstanding. 144 FIRST HORIZON NATIONAL CORPORATION Note 19 (cid:2) Stock Options, Restricted Stock, and Dividend Reinvestment Plans (continued) Stock and stock unit awards. A summary of restricted and performance stock and unit activity during the year ended December 31, 2017, is presented below: Nonvested on January 1, 2017 Shares/units granted Shares/units vested Shares/units cancelled Nonvested on December 31, 2017 Weighted average grant date fair value (per share) (b) 11.28 18.83 11.64 10.51 12.92 Shares/ Units (a) 4,004,402 1,238,754 (847,107) (424,833) 3,971,216 (a) Includes only units that settle in shares and nonvested performance units are included at 100% payout level. (b) The weighted average grant date fair value for shares/units granted in 2016 and 2015 was $12.90 and $13.90, respectively. On December 31, 2017, there was $27.6 million of unrecognized compensation cost related to nonvested restricted stock awards. That cost is expected to be recognized over a weighted-average period of 2.5 years. The total grant date fair value of shares vested during 2017, 2016 and 2015, was $9.9 million, $9.7 million and $9.9 million, respectively. Stock option awards. Currently FHN operates only a single option program, calling for annual grants of service- vested options to executives. In the past, however, option programs varied widely in their uses and terms, and many old-program options, granted under the ECP or its predecessor plans, remain outstanding today. Except for substitute options (discussed below), all options granted since 2005 provide for the issuance of FHN common stock at a price fixed at its fair market value on the grant date. Except for substitute options, converted options and a special retention stock option award to the CEO in 2016, all options granted since 2008 vest fully no later than the fourth anniversary of grant, and all such options expire seven years from the grant date. Substitute options can be issued under the ECP in exchange for options of an acquired company that are canceled in a merger. The price, vesting, expiration, and other terms of the substitute options economically mirror those of the canceled options. FHN issued substitute options in the TAF transaction which closed in October, 2015. Converted options from CBF are all fully vested and expire ten years from grant date. The 2016 retention award vests beginning on the fourth anniversary of grant and extends through the sixth anniversary of grant. A deferral program, which was discontinued in 2005, allowed for foregone compensation plus the exercise price to equal the fair market value of the stock on the date of grant if the grantee agreed to receive the options in lieu of compensation. Deferral options still outstanding expire 20 years from the grant date. The summary of stock option activity for the year ended December 31, 2017, is shown below: January 1, 2017 Options converted from CBF Options granted Options exercised Options expired/cancelled December 31, 2017 Options exercisable Options expected to vest Weighted Average Exercise Price (per share) Weighted Average Remaining Contractual Term (years) Aggregate Intrinsic Value (thousands) 17.86 11.54 19.73 13.66 27.21 16.80 17.65 14.11 3.18 2.56 5.13 34,003 24,646 9,358 Options Outstanding 5,937,156 1,059,685 423,638 (475,995) (335,913) 6,608,571 5,016,496 1,592,075 The total intrinsic value of options exercised during 2017, 2016 and 2015 was $2.5 million, $10.6 million and $2.8 million, respectively. On December 31, 2017, there was $2.2 million of unrecognized compensation cost FIRST HORIZON NATIONAL CORPORATION 145 Note 19 (cid:2) Stock Options, Restricted Stock, and Dividend Reinvestment Plans (continued) related to nonvested stock options. That cost is expected to be recognized over a weighted-average period of 3.2 years. FHN granted or converted 1,483,323, 971,328 and 595,229 stock options with a weighted average fair value of $4.69, $2.95 and $4.01 per option at grant date in 2017, 2016 and 2015, respectively. FHN used the Black-Scholes Option Pricing Model to estimate the fair value of stock options granted or converted in 2017, 2016, and 2015 with the following assumptions: 2017 2016 2015 Expected dividend yield Expected weighted-average lives of options granted Expected weighted-average volatility Expected volatility range Risk-free interest rate 1.82% 6.09 years 26.90% 2.41% 6.19 years 32.84% 24.36 – 29.44% 30.73 – 34.95% 23.67 – 40.85% 1.28% 1.68% 6.18 years 32.26% 1.68% 2.07% Expected lives of options granted are determined based on the vesting period, historical exercise patterns and contractual term of the options. FHN uses a blend of historical and implied volatility in determining expected volatility. A portion of the weighted average volatility rate is derived by compiling daily closing stock prices over a historical period approximating the expected lives of the options. Additionally, because of market volatility due to economic conditions and the impact on stock prices of financial institutions, FHN also incorporates a measure of implied volatility so as to incorporate more recent market conditions in the estimation of future volatility. Compensation Cost. The compensation cost that has been included in the Consolidated Statements of Income pertaining to stock-based awards was $20.6 million, $17.5 million, and $13.8 million for 2017, 2016, and 2015, respectively. The corresponding total income tax benefits recognized were $7.9 million in 2017, $6.7 million in 2016, and $5.3 million in 2015. Authorization. Consistent with Tennessee state law, only authorized, but unissued, stock may be utilized in connection with any issuance of FHN common stock which may be required as a result of stock based compensation awards. FHN has obtained authorization from the Board of Directors to repurchase up to certain number of shares, related to issuance under the ECP and older stock award plans. These authorizations are automatically adjusted for stock splits and stock dividends. Repurchases are authorized to be made in the open market or through privately negotiated transactions and will be subject to market conditions, accumulation of excess equity, legal and regulatory restrictions, and prudent capital management. FHN does not currently expect to repurchase a material number of shares under the compensation plan-related repurchase program during 2018. Dividend reinvestment plan. The Dividend Reinvestment and Stock Purchase Plan authorizes the sale of FHN’s common stock from stock acquired on the open market to shareholders who choose to invest all or a portion of their cash dividends or make optional cash payments of $25 to $10,000 per quarter without paying commissions. The price of stock purchased on the open market is the average price paid. 146 FIRST HORIZON NATIONAL CORPORATION Note 20 (cid:2) 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, North Carolina, South Carolina, Florida and other selected markets. Regional banking also provides investments, financial planning, trust services and asset management, mortgage banking, 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, gain/(loss) on extinguishment of debt, and acquisition- and integration-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.

(a) 2017 includes a $14.3 million pre-tax loss from the repurchase of equity securities previously included in a financing transaction. 148 FIRST HORIZON NATIONAL CORPORATION Note 21 (cid:2) 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 mortgage service rights ("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 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.

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 $1.8 million, $1.8 million, and $3.4 million during 2017, 2016, and 2015, respectively.

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 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 FIRST HORIZON NATIONAL CORPORATION 151 Note 21 (cid:2) Variable Interest Entities (continued) 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. Proprietary Trust Preferred Issuances. In conjunction with the acquisition of CBF, FHN acquired junior subordinated debt totaling $212.4 million underlying multiple issuances of trust preferred debt by institutions previously acquired by CBF. All of these trusts are considered VIEs because the ownership interests from the capital contributions to these trusts are not considered “at risk” in evaluating whether the holders of the equity investments at risk in the trusts have the power through voting rights, or similar rights, to direct the activities that most significantly impact the entities’ economic performance. Thus, FHN cannot be the trusts’ primary beneficiary because its ownership interests in the trusts are not considered variable interests as they are not considered “at risk”. Consequently, none of the trusts are consolidated by FHN. 152 FIRST HORIZON NATIONAL CORPORATION Note 21 (cid:2) Variable Interest Entities (continued) The following table summarizes FHN’s nonconsolidated VIEs as of December 31, 2017: (Dollars in thousands) Type Low income housing partnerships Other tax credit investments (b) (c) Small issuer trust preferred holdings (d) On-balance sheet trust preferred securitization Proprietary residential mortgage securitizations Holdings of agency mortgage-backed securities (d) Commercial loan troubled debt restructurings (g) Sale-leaseback transaction Proprietary trust preferred issuances (i) Maximum Loss Exposure Liability Recognized Classification $ 94,798 20,394 332,455 48,817 2,151 5,349,287 19,411 14,827 - $ 33,348 - - 65,357 - - - - 212,378 (a) Other assets Loans, net of unearned income (e) Trading securities (f) Loans, net of unearned income (h) Term borrowings (a) Maximum loss exposure represents $61.5 million of current investments and $33.3 million of accrued contractual funding commitments.

FIRST HORIZON NATIONAL CORPORATION 153 Note 22 (cid:2) 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 Statements of Condition. This change has no effect on hedge accounting or gains/losses for the applicable derivative contracts. On December 31, 2017 and 2016, respectively, FHN had $27.8 million and $47.8 million of cash receivables and $28.3 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 154 FIRST HORIZON NATIONAL CORPORATION Note 22 (cid:2) Derivatives (continued) 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 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 $173.9 million and $229.7 million for the years ended December 31, 2017 and 2016, respectively. Trading revenues are inclusive of both derivative and non-derivative financial instruments, and are included in fixed income noninterest income.

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 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 $.1 million and $1.6 million in Derivative assets as of December 31, 2017 and 2016. There was an insignificant level of ineffectiveness related to this hedge.

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.

Prior to third quarter 2017, FHN hedged held-to-maturity trust preferred loans which had an initial fixed rate term before conversion to a floating rate. FHN had entered into pay fixed, receive floating interest rate swaps to hedge the interest rate risk associated with the initial term. Interest paid or received for these swaps was recognized as FIRST HORIZON NATIONAL CORPORATION 157 Note 22 (cid:2) Derivatives (continued) an adjustment of the interest income of the assets whose risk was being hedged. Basis adjustments remaining at the end of the hedge term were amortized as an adjustment to interest income over the remaining life of the loans. Gains or losses were included in Other income and commissions on the Consolidated Statements of Income. These hedges expired 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 December 31, 2017 and 2016, the derivative liabilities associated with the sales of Visa Class B shares were $5.6 million and $6.2 million, respectively. See the Visa Matters section of Note 17 – Contingencies and Other Disclosures for more information regarding FHN’s Visa shares. FHN utilizes cross currency swaps and cross currency interest rate swaps to economically hedge its exposure to foreign currency risk and interest rate risk associated with non-U.S. dollar denominated loans. As of December 31, 2017 and 2016, these loans were valued at $1.5 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 158 FIRST HORIZON NATIONAL CORPORATION Note 22 (cid:2) Derivatives (continued) 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 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 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 $23.3 million of assets and $34.5 million of liabilities on December 31, 2017, and $35.9 million of assets and $49.0 million of liabilities on December 31, 2016. As of December 31, 2017 and 2016, FHN had received collateral of $119.3 million and $137.6 million and posted collateral of $18.9 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 $22.8 million of assets and $19.4 million of liabilities on December 31, 2017, and $35.9 million of assets and $19.6 million of liabilities on December 31, 2016. As of December 31, 2017 and 2016, FHN had received collateral of $118.6 million and $137.5 million and posted collateral of $6.7 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. FIRST HORIZON NATIONAL CORPORATION 159 Note 22 (cid:2) Derivatives (continued) 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.

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 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.

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.

In fourth quarter 2017, FHN recognized $3.0 million and $.8 million of impairments on long-lived assets in its Corporate and Regional Banking segments, respectively, associated with efforts to more efficiently utilize its branch locations, including integration with branches acquired from CBF. In first quarter 2016, FHN’s Regional Banking segment recognized $3.7 million of impairments on long-lived assets for similar efficiency efforts. 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. In third quarter 2017, FHN’s Corporate segment recognized $2.0 million of impairments on long-lived technology assets associated with the transition to expanded processing capacity that will be required upon completion of the FIRST HORIZON NATIONAL CORPORATION 167 Note 24 (cid:2) Fair Value of Assets and Liabilities (continued) merger with CBF. The fair values of the assets impaired were determined using a discounted cash flow approach which reflected short estimated remaining lives and considered estimated salvage values.

Increases (decreases) in estimated prepayment rates and bond equivalent yields negatively (positively) affect the value of SBA interest only strips. Management additionally considers whether the loans underlying 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 Other Real Estate Owned. Collateral-dependent loans and OREO 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 OREO 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 170 FIRST HORIZON NATIONAL CORPORATION Note 24 (cid:2) Fair Value of Assets and Liabilities (continued) 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”) except for mortgage origination operations acquired from CBF. 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. (Dollars in thousands) Residential real estate loans held-for-sale reported at fair value: Total loans Nonaccrual loans Loans 90 days or more past due and still accruing (Dollars in thousands) Residential real estate loans held-for-sale reported at fair value: Total loans Nonaccrual loans Loans 90 days or more past due and still accruing December 31, 2017 Fair value carrying amount Aggregate unpaid principal Fair value carrying amount less aggregate unpaid principal $20,881 5,783 - $29,755 10,881 - $(8,874) (5,098) - December 31, 2016 Fair value carrying amount Aggregate unpaid principal Fair value carrying amount less aggregate unpaid principal $24,269 6,775 211 $35,262 12,910 331 $(10,993) (6,135) (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 FIRST HORIZON NATIONAL CORPORATION 171 Note 24 (cid:2) Fair Value of Assets and Liabilities (continued) elected the fair value option are included in current period earnings with classification in the income statement line item reflected in the following table: (Dollars in thousands) Changes in fair value included in net income: Mortgage banking noninterest income Loans held-for-sale Year Ended December 31 2017 2016 2015 $1,547 $3,380 $2,765 For the years ended December 31, 2017, 2016 and 2015, the amounts for residential real estate loans held-for- sale included gains of $.5 million, $1.5 million and $.4 million, respectively, 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 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 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 investments in mutual funds. Valuations of available-for-sale securities are performed using observable inputs obtained from market transactions in similar 172 FIRST HORIZON NATIONAL CORPORATION Note 24 (cid:2) Fair Value of Assets and Liabilities (continued) 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 Statements of Condition which is considered to approximate fair value. 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. Non-mortgage consumer loans held-for-sale are valued using current market pricing for similar assets with adjustments for differences in credit standing (delinquency, historical default rates for similar loans), yield, collateral values and prepayment rates. If pricing for similar assets is not available, a discounted cash flow methodology is utilized, which incorporates all of these factors into an estimate of investor required yield for the discount rate. 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 fair value of other non-residential real estate loans held-for-sale is approximated by their carrying values based on current transaction values. Loans, net of unearned income. Loans, net of unearned income are recognized at the amount of funds advanced, less charge-offs and an estimation of credit risk represented by the allowance for loan losses. The fair value estimates for disclosure purposes differentiate loans based on their financial characteristics, such as product classification, vintage, loan category, pricing features, and remaining maturity. FIRST HORIZON NATIONAL CORPORATION 173 Note 24 (cid:2) Fair Value of Assets and Liabilities (continued) The fair value of floating rate loans is estimated through comparison to recent market activity in loans of similar product types, with adjustments made for differences in loan characteristics. In situations where market pricing inputs are not available, fair value is considered to approximate book value due to the monthly repricing for commercial and consumer loans, with the exception of floating rate 1-4 family residential mortgage loans which reprice annually and will lag movements in market rates. The fair value for floating rate 1-4 family mortgage loans is calculated by discounting future cash flows to their present value. Future cash flows are discounted to their present value by using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same time period. Prepayment assumptions based on historical prepayment speeds and industry speeds for similar loans have been applied to the floating rate 1-4 family residential mortgage portfolio. The fair value of fixed rate loans is estimated through comparison to recent market activity in loans of similar product types, with adjustments made for differences in loan characteristics. In situations where market pricing inputs are not available, fair value is estimated by discounting future cash flows to their present value. Future cash flows are discounted to their present value by using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same time period. Prepayment assumptions based on historical prepayment speeds and industry speeds for similar loans have been applied to the fixed rate mortgage and installment loan portfolios. For all loan portfolio classes, adjustments are made to reflect liquidity or illiquidity of the market. Such adjustments reflect discounts that FHN believes are consistent with what a market participant would consider in determining fair value given current market conditions. Individually impaired loans are measured using either a discounted cash flow methodology or the estimated fair value of the underlying collateral less costs to sell, if the loan is considered collateral-dependent. In accordance with accounting standards, the discounted cash flow analysis utilizes the loan’s effective interest rate for discounting expected cash flow amounts. Thus, this analysis is not considered a fair value measurement in accordance with ASC 820. However, the results of this methodology are considered to approximate fair value for the applicable loans. Expected cash flows are derived from internally-developed inputs primarily reflecting expected default rates on contractual cash flows. For loans measured using the estimated fair value of collateral less costs to sell, fair value is estimated using appraisals of the collateral. Collateral values are monitored and additional write- downs are recognized if it is determined that the estimated collateral values have declined further. Estimated costs to sell are based on current amounts of disposal costs for similar assets. Carrying value is considered to reflect fair value for these loans. Derivative assets and liabilities. The fair value for forwards and futures contracts is based on current transactions involving identical securities. Futures contracts are exchange-traded and thus have no credit risk factor assigned as the risk of non-performance is limited to the clearinghouse used. Valuations of other derivatives (primarily interest rate related swaps) are based on inputs observed in active markets for similar instruments. Typical inputs include the LIBOR curve, Overnight Indexed Swap (“OIS”) curve, option volatility, and option skew. In measuring the fair value of these derivative assets and liabilities, FHN has elected to consider credit risk based on the net exposure to individual counterparties. Credit risk is mitigated for these instruments through the use of mutual margining and master netting agreements as well as collateral posting requirements. For derivative contracts with daily cash margin requirements that are considered settlements, the daily margin amount is netted within derivative assets or liabilities. Any remaining credit risk related to interest rate derivatives is considered in determining fair value through evaluation of additional factors such as customer loan grades and debt ratings. Foreign currency related derivatives also utilize observable exchange rates in the determination of fair value. The determination of fair value for FHN’s derivative liabilities associated with its prior sales of Visa Class B shares are classified within Level 3 in the fair value measurements disclosure as previously discussed in the unobservable inputs discussion. OREO. OREO primarily consists of properties that have been acquired in satisfaction of debt. These properties are carried at the lower of the outstanding loan amount or estimated fair value less estimated costs to sell the real estate. Estimated fair value is determined using appraised values with subsequent adjustments for deterioration in values that are not reflected in the most recent appraisal. 174 FIRST HORIZON NATIONAL CORPORATION Note 24 (cid:2) Fair Value of Assets and Liabilities (continued) Nonearning assets. For disclosure purposes, nonearning financial assets include cash and due from banks, accrued interest receivable, and fixed income receivables. Due to the short-term nature of cash and due from banks, accrued interest receivable, and fixed income receivables, the fair value is approximated by the book value. Other assets. For disclosure purposes, other assets consist of tax credit investments and deferred compensation assets that are considered financial assets. Tax credit investments accounted for under the equity method are written down to estimated fair value quarterly based on the estimated value of the associated tax credits which incorporates estimates of required yield for hypothetical investors. The fair value of all other tax credit investments is estimated using recent transaction information with adjustments for differences in individual investments. Deferred compensation assets are recognized at fair value, which is based on quoted prices in active markets. Defined maturity deposits. The fair value of these deposits is estimated by discounting future cash flows to their present value. Future cash flows are discounted by using the current market rates of similar instruments applicable to the remaining maturity. For disclosure purposes, defined maturity deposits include all time deposits. Undefined maturity deposits. In accordance with ASC 825, the fair value of these deposits is approximated by the book value. For the purpose of this disclosure, undefined maturity deposits include demand deposits, checking interest accounts, savings accounts, and money market accounts. Short-term financial liabilities. The fair value of federal funds purchased, securities sold under agreements to repurchase and other short-term borrowings are approximated by the book value. The carrying amount is a reasonable estimate of fair value because of the relatively short time between the origination of the instrument and its expected realization. Term borrowings. The fair value of term borrowings is based on quoted market prices or dealer quotes for the identical liability when traded as an asset. When pricing information for the identical liability is not available, relevant prices for similar debt instruments are used with adjustments being made to the prices obtained for differences in characteristics of the debt instruments. If no relevant pricing information is available, the fair value is approximated by the present value of the contractual cash flows discounted by the investor’s yield which considers FHN’s and FTBNA’s debt ratings and whether the debt is currently callable. Secured borrowings also consider the values of the associated assets and whether overcollateralization exists. Other noninterest-bearing liabilities. For disclosure purposes, other noninterest-bearing financial liabilities include accrued interest payable and fixed income payables. Due to the short-term nature of these liabilities, the book value is considered to approximate fair value. Loan commitments. Fair values of these commitments are based on fees charged to enter into similar agreements taking into account the remaining terms of the agreements and the counterparties’ credit standing. Other commitments. Fair values of these commitments are based on fees charged to enter into similar agreements. The following fair value estimates are determined as of a specific point in time utilizing various assumptions and estimates. The use of assumptions and various valuation techniques, as well as the absence of secondary markets for certain financial instruments, reduces the comparability of fair value disclosures between financial institutions. Due to market illiquidity, the fair values for loans, net of unearned income, loans held-for-sale, and term borrowings as of December 31, 2017 and 2016, involve the use of significant internally-developed pricing assumptions for certain components of these line items. The assumptions and valuations utilized for this disclosure are considered to reflect inputs that market participants would use in transactions involving these instruments as of the measurement date. The valuations of legacy assets, particularly consumer loans within the non-strategic segment and TRUP loans, are influenced by changes in economic conditions since origination and risk perceptions of the financial sector. These considerations affect the estimate of a potential acquirer’s cost of capital and cash flow volatility assumptions from these assets and the resulting fair value measurements may depart significantly from FHN’s internal estimates of the intrinsic value of these assets. FIRST HORIZON NATIONAL CORPORATION 175 Note 24 (cid:2) Fair Value of Assets and Liabilities (continued) Assets and liabilities that are not financial instruments have not been included in the following table such as the value of long-term relationships with deposit and trust customers, premises and equipment, goodwill and other intangibles, deferred taxes, and certain other assets and other liabilities. Additionally, these measurements are solely for financial instruments as of the measurement date and do not consider the earnings potential of our various business lines. Accordingly, the total of the fair value amounts does not represent, and should not be construed to represent, the underlying value of FHN.
