FORWARD-LOOKING STATEMENTS

This report on Form 10-K, including materials incorporated into it, contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 with respect to our 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 our 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 us 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 our hedging practices; technological changes; fraud, theft, or other incursions through conventional, electronic, or other means directly or indirectly affecting us or our customers, business counterparties, or competitors; demand for our product offerings; new products and services in the industries in which we operate; 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.

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 us; and our success in executing our 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.
We assume no obligation to update or revise any forward-looking statements that are made in this report on Form 10-K or in any other statement, release, report, or filing from time to time. Actual results could differ and expectations could change, possibly materially, because of one or more factors, including those factors listed above or presented elsewhere in this report, or in those factors listed in material incorporated by reference into this report. In evaluating forward-looking statements and assessing our prospects, readers of this report should carefully consider the factors mentioned above along with the additional risk factors discussed in Items 1 and 1A of this report and in 2019 MD&A (Item 7), among others.

PART I

ITEM 1. BUSINESS
------------

Our Businesses

First Horizon National Corporation (“FHN,” “First Horizon,” the “Corporation,” “we,” or “us”) is a Tennessee corporation. We are headquartered in Memphis, Tennessee. We are a bank holding company under the Bank Holding Company Act, and are a financial holding company under the Gramm-Leach-Bliley Act. At December 31, 2019, we had total consolidated assets of $43.3 billion.
We provide diversified financial services primarily through our principal subsidiary, First Horizon Bank (the “Bank”). The Bank is a Tennessee banking corporation headquartered in Memphis, Tennessee. The Bank and its subsidiaries conduct the Bank’s traditional and specialty banking businesses principally under the FIRST HORIZON BANK brand, its wealth management business principally under the First Horizon Advisors brand, and its fixed income business principally under the FHN FINANCIAL Financial brand.
The Bank was founded in 1864 as First National Bank of Memphis. FHN was incorporated in 1968 to be the Bank’s holding company.
During 2019 approximately 35% of our consolidated revenues were provided by fee and other noninterest income, and approximately 65% of revenues were provided by net interest income.
As a financial holding company, we coordinate the financial resources of the consolidated enterprise and maintain systems of financial, operational, and administrative control intended to coordinate selected policies and activities, including as described in Item 9A of Part II of this report.
Business Segments
Our financial results of operations are reported through operational business segments which are not closely related to the legal structure of our subsidiaries. We operate through four business segments: regional banking, fixed income, corporate, and non-strategic. We sometimes refer to regional banking, fixed income, and corporate as our “core” business segments.
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 3

Financial and other additional information concerning our segments-including information concerning assets, revenues, and financial results-appears in our 2019 MD&A (Item 7) and in Note 20-Business Segment Information, of our 2019 Financial Statements (Item 8).
The Bank
During 2019, through its various business lines, including consolidated subsidiaries, the Bank generated gross revenue (net interest income plus noninterest income) of approximately $2.3 billion and generated a substantial majority of our consolidated revenue from continuing operations. At December 31, 2019, the Bank had $43.1 billion in total assets, $32.8 billion in total deposits, and $30.9 billion in total loans (net of unearned income). Among Tennessee headquartered banks, the Bank ranked 1 st in Tennessee deposit market share at June 30, 2019 based on FDIC data.
Physical Business Locations
At December 31, 2019, FHN’s subsidiaries had over 300 business locations in 20 U.S. states, excluding off-premises ATMs. Almost all of those locations were banking centers and FHN Financial offices.
At year-end, the Bank had 272 banking centers in seven states:
Banking Centers at Year End

State | # | State | #
Tennessee | 158 | Mississippi | 5
North Carolina | 68 | Georgia | 1
Florida | 29 | Texas | 1
South Carolina | 10 |  |

The Bank also has other customer-service offices, including private client and commercial loan offices, as well as operational and administrative offices.
At December 31, 2019, FHN Financial’s fixed income and other products and services were offered through 29 offices in 18 states across the U.S.

Information about the net interest income and noninterest income we obtained from our largest categories of products and services appears under the caption “Income Statement Review-2019 Compared to 2018” beginning on page 48 of our 2019 MD&A (Item 7), which information is incorporated into this Item 1 by reference.
Loans & Deposits
Our largest asset would be our loan portfolio-if all of our loans were viewed collectively-and lending is a critical, core business for us. Similarly, our largest resource is our deposit base, and deposit-taking also is a critical, core business. At year-end 2019, we had total net loans of $30.9 billion and total deposits of $32.4 billion. Most of our loans and deposits are held in our regional banking segment. The tables below provide an overview of our loan and deposit balances at December 31, 2019 or averaged over the year 2019.
Geographically, nearly half of our loans originate from Tennessee and North Carolina, with no other state accounting for 10%. Three-fourths of our deposits are associated with Tennessee, and 90% are from Tennessee and North Carolina.

FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 4

*Averages for 2019.
These tables show that our lending outside of Tennessee is funded in significant part by deposits from our Tennessee markets, and a significant portion of funding for our commercial lending comes from consumer deposits. Keeping our funding uses and sources in balance is a critical function for us. Excess deposits most typically are invested in investments permitted by our regulators, while excess lending most typically is funded with borrowing. Because loans and deposits fluctuate constantly, we maintain access to significant non-deposit liquidity sources, primarily short-term borrowing.
Most of our commercial loans are traditional, unsecured “commercial, financial, and industrial,” or “C&I,” loans, and most of the rest are secured “commercial real estate,” or “CRE,” loans. Within C&I, nearly 36% of loans are to businesses in the financial services industry, including mortgage lending companies, and the rest are in a wide range of industries.
Commercial Loans by Line of Business

All Commercial Loans* |  | All C&I Loans*
C&I | 82 | % |  | Mortg. Lenders | 22 | %
CRE | 18 | % |  | Finance & Insur. | 14 | %
|  |  | Health care | 8 | %
|  |  | Real estate rental | 7 | %
|  |  | Hospitality | 7 | %
|  |  | Wholesale trade | 7 | %
|  |  | Manufacturing | 6 | %
|  |  | Public Admin. | 4 | %
|  |  | Retail trade | 4 | %
|  |  | Other C&I | 21 | %
*At December 31, 2019. |  |  |

The C&I portfolio was $20.1 billion on December 31, 2019, 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 C&I balances as of December 31, 2019, are in Tennessee (31%), North Carolina (10%), California (9%), Texas (6%), Florida (6%),Georgia (4%), and South Carolina (3%), with no other state representing more than 3% of the C&I portfolio.
Further information regarding our loans is provided in Note 4-Loans within our 2019 Financial Statements (Item 8), and under the captions “Statement of Condition Review-2019 Compared to 2018” beginning on page 59, and “Asset Quality-Trend Analysis of 2019 compared to 2018” beginning on page 65, of our 2019 MD&A (Item 7), which disclosures are incorporated into this Item 1 by reference.

Significant Business Developments Over Past Five Years

Over the past five years, key strategic priorities for us have included:

• | targeted expansion of consumer and commercial banking products and markets

• | opportunistic expansion of commercial lending, mainly through acquisition transactions, talent development, and talent acquisitions

• | vigorous discipline in controlling expenses not closely related to revenue production

• | managing our business units and products with a strong emphasis on risk-adjusted returns on invested capital

• | robust emphasis on providing exceptional customer experience as a primary means to differentiate us from competitors

• | investment in scalable technology and other infrastructure to attract and retain business, and to support expansion.

Examples of our implementation of these priorities include:

• | In 2017 we acquired Capital Bank, which had $10 billion of total assets and nearly 200 banking centers in four southeastern U.S. states.

• | Other acquisitions during this period include TrustAtlantic Bank (2015) and a restaurant franchise finance business and portfolio (2016).

• | We have made key talent hires in critical areas throughout our company, with the main focus on organically growing economically profitable business lines inside and outside our traditional markets.

FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 5

• | We have pruned our physical network to reflect long-term trends in customer usage of physical banking centers, and correspondingly are making more efficient use of other physical facilities.

• | Organic and acquisitive loan growth in regional banking has more than offset loan attrition from the non-strategic segment, where legacy loan portfolios are in long-term wind-down.

• | Organic commercial loan growth has been strong in specialty lending areas, such as lending to mortgage companies, where margins tend to be better but outstanding balances tend to fluctuate seasonally and cyclically.

The following table provides selected data concerning revenues, expenses, assets, liabilities, and shareholders’ equity for the past five years.

Key Factors
Several factors complicate comparisons among the past five years. Key among those are:

• | Capital Bank. Many year-end financial figures increased substantially in 2017 due to the Capital Bank transaction. Full-year operating results were less noticeably impacted until 2018, because the Capital transaction closed late in 2017.

• | Tax Reform. Corporate tax reform in December, 2017 resulted in significant negative adjustments to net deferred tax asset balance, driving a large net loss in fourth quarter that year. Financial results in 2018 and 2019, in contrast, benefited significantly from lower tax rates compared to earlier years.

• | Interest Rate Policy. Although interest rates during each of these years were quite low by historical standards, they were raised modestly starting in 2015, more vigorously in 2018, and then reduced three times in 2019. These changes impacted our net interest margin up and down. Net interest margin is a measure of the profit we make on loans and other earning assets in relation to our cost of deposits and other funding sources.

• | Sale of Visa Class B Stock. In 2018 we sold our remaining legacy stock holdings of Visa, recognizing a

pretax gain that significantly increased noninterest income that year.

• | Very low loan loss rates. During these five years, our provision for loan losses was unusually low. When provision is low, differences from year to year can be idiosyncratic, driven by one or just a few customers.

• | Fixed Income Volatility. For several of these years, market conditions were quite subdued for our fixed income segment. In 2019, however, increased market volatility and the downward direction of interest rates resulted in much higher trading volume and noninterest income in that segment.

Trends
Noteworthy trends during this period include:

• | Net loan growth has driven asset growth. Overall growth has been strong despite run-off of non-strategic loans. The large increase in 2017 was driven by the Capital Bank merger, and 2018 was impacted by the Capital Bank systems integration effort. Growth in 2016 (vs. 2015) and in 2019 (vs. 2018) was organic.

• | Growth in net interest income was significant through 2018, driven by net loan growth, interest rate increases, and (in 2018) the Capital Bank merger. Growth flattened in 2019 as net loan growth was offset by interest rate declines.

FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 6

• | Through 2018, an overall down-trend in noninterest income was due mainly to lower fixed income revenues, driven by challenging market conditions. The large increase in 2018 was mainly due to the Visa stock sale. That trend reversed in 2019 as interest rates declined, market volatility increased, and fixed income revenues improved.

• | Deposits grew significantly through 2018. Much of that growth was organic, helped by a rising rate environment. The large uptick in 2017 was driven substantially by the Capital Bank transaction. Total deposit growth moderated in 2019, as solid regional banking deposit growth offset deliberate reductions in (more expensive) market-indexed deposits.

Exited Businesses
Since the 2008-09 recession, we have focused on traditional banking and fixed income products and services. We exited our legacy nation-wide mortgage banking business in 2008, though we continue to manage related legal exposures and the wind-down of a still-sizable loan portfolio. We partially or fully exited other businesses since 2008. Exited businesses are managed in our non-strategic segment.

Significant Business Developments Expected in 2020

We signed agreements late in 2019 for two transactions that we expect to close in 2020. The larger of them will significantly transform our company in terms of size, geographic reach, and the scope of financial services we offer.
30-Branch Acquisition
In the fourth quarter of 2019 we announced an agreement to purchase 30 branches in North Carolina (20), Virginia (8), and Georgia (2) from SunTrust Bank (now Truist Bank). Those branches are in markets we do not serve currently, or in which we do not have a leading market position. Along with the branch facilities, we will acquire related loans and assume deposits. At the time of announcement, we estimated the loans to be $0.4 billion and the deposits to be $2.4 billion. The 30-branch acquisition is scheduled to close in the second quarter of 2020.
IBKC Merger of Equals
In the fourth quarter of 2019 we announced a merger-of-equals agreement with IBERIABANK Corporation (“IBKC”). IBKC is the parent company of IBERIABANK based in Lafayette, Louisiana. At the time of announcement, IBKC, with $32 billion of total assets, had over 190 banking centers in 11 states: Louisiana, Texas, Arkansas, Tennessee, Mississippi, Alabama, Georgia, Florida, North and South Carolina, and New York. IBKC’s largest concentrations of banking centers are in Louisiana
and Florida. IBKC offers many of the same financial services that we offer, but exceeds us in several areas, most notably in equipment financing and title insurance.
The combined company, on a September 30, 2019 pro-forma basis which includes the 30-branch acquisition, would have had $78 billion in assets, $59 billion in deposits, and $55 billion in loans. After closing, our board will expand to 17 directors, of which nine will be from legacy FHN and eight will be from legacy IBKC. IBKC shareholders will receive 4.584 shares of our common stock for each IBKC common share held, and collectively will be issued 44% of our post-closing outstanding common shares. In order to accommodate a stock issuance of that size, we must amend our corporate charter to increase the number of common shares we are authorized to issue.
The IBKC transaction is subject to approval by shareholders of both companies, regulatory approvals, and other customary contractual conditions. We expect to hold a special meeting of our shareholders to vote on the IBKC transaction, including related amendments to our corporate charter, in the second quarter of 2020, and we expect the IBKC merger to close in mid-2020.

Other General Information

Strategic Transactions
An element of our business strategy is to consider acquisitions and divestitures that would enhance long-term shareholder value. Significant acquisitions and divestitures which closed during the past three years are described in
Note 2-Acquisitions and Divestitures, of our 2019 Financial Statements (Item 8), which information is incorporated into this Item 1 by this reference.
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 7

As mentioned above, in November 2017 we legally closed our acquisition of Capital Bank. In May 2018 we completed systems integration for that transaction.
Also as mentioned above, in November 2019 we agreed to acquire 30 branches in three southeastern states, and we entered into a merger-of-equals agreement with IBKC. Both are expected to close in 2020. The IBKC merger will significantly transform our company in terms of size, geographic reach, and the scope of financial services we offer.
Subsidiaries
FHN’s consolidated operating subsidiaries at December 31, 2019 are listed in Exhibit 21.
The Bank is a government securities dealer. The FHN Financial division of the Bank is registered with the SEC as a municipal securities dealer and the FHN Financial Municipal Advisors division of the Bank is registered with the SEC as a municipal adviser. The Bank is supervised and regulated as described in “Supervision and Regulation” in this Item below.
Martin and Company, Inc., First Horizon Advisors, Inc., and FHN Financial Main Street Advisors, LLC are registered with the SEC as investment advisers. First Horizon Advisors, Inc. and FHN Financial Securities Corp. are registered as broker-dealers with the SEC and all states where they conduct business for which registration is required. First Horizon Insurance Services, Inc., FHIS, Inc., and First Horizon Insurance Agency, Inc. are licensed as insurance agencies in all states where they do business for which licensing is required. FHN Financial Securities Corp., First Horizon Advisors, Inc., First Horizon Insurance Services, Inc., FHIS, Inc., and First Horizon Insurance Agency, Inc. are financial subsidiaries under the Gramm-Leach-Bliley Act. First Horizon Advisors, Inc. is licensed as an insurance agency in the states where it does business for which licensing is required for the sale of annuity products. First Horizon Insurance Agency, Inc. is inactive.
Customer Concentration
Neither we nor any of our significant subsidiaries is dependent upon a single customer or very few customers.
Seasonality
We do not experience material seasonality. We do experience seasonal variation in certain revenues, expenses, and credit trends. Historically, these variations have somewhat increased certain expenses for the regional banking and fixed income segments, and somewhat diminished certain revenues for the regional banking segment, principally in the first quarter each year. In addition, we experience seasonal variation in certain asset and liability balances, principally in the fourth (commercial lending related to consumer mortgages, certain trading balances, and certain employee-related reserves) and first (mortgage-related lending) quarters.
Employees
At December 31, 2019, FHN and its subsidiaries had 5,017 employees, or 4,994 full-time-equivalent employees, not including contract labor for certain services.

Supervision and Regulation

Scope of this Section
This section describes certain of the material elements of the regulatory framework applicable to bank and financial holding companies and their subsidiaries, and to companies engaged in securities and insurance activities. It also provides certain specific information about us. To the extent that the following information describes statutory and regulatory provisions, it is qualified in its entirety by
express reference to each of the particular statutory and regulatory provisions. A change in applicable statutes, regulations, or regulatory policy may have a material effect on our business.
Overview
FHN
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 8

FHN is a bank holding company and financial holding company within the meaning of the Bank Holding Company Act of 1956, as amended (the “BHCA”), and is registered with the Federal Reserve. We are subject to the regulation and supervision of, and to examination by, the Federal Reserve under the BHCA. We are required to file with the Federal Reserve annual reports and such additional information as the Federal Reserve may require pursuant to the BHCA.
A bank holding company that is not a financial holding company is limited to engaging in “banking” and activities found by the Federal Reserve to be “closely related to banking.” Eligible bank holding companies that elect to become financial holding companies may affiliate with securities firms and insurance companies and engage in activities that are “financial in nature.” “Financial” activities are broader in scope than those which are “closely related to banking.” See “Financial Activities other than Banking” beginning on page 14 below.
The Federal Reserve may approve an application by a bank holding company to acquire a bank located outside the acquirer’s principal state of operations without regard to whether the transaction is prohibited under state law, although state law may still impose certain requirements. See “Interstate Banking and Branching” beginning on page 13, and “Community Reinvestment Act (“CRA”)” beginning on page 13.
The Tennessee Bank Structure Act of 1974, among other things, prohibits (subject to certain exceptions) a bank holding company from acquiring a bank for which the home state is Tennessee (a “Tennessee bank”) if, upon consummation, the company would directly or indirectly control 30% or more of the total deposits in insured depository institutions in Tennessee. As of June 30, 2019, we estimate that we held approximately 15.39% of such deposits.
The Bank
Our Bank is a Tennessee banking corporation subject to the regulation and supervision of, and to examination by, the TDFI. In addition to general supervision and examination powers, the TDFI has the power to approve mergers with the Bank, the Bank’s issuance of preferred stock or capital notes, the establishment of banking centers, and many other corporate actions.
The Bank has chosen to be a member of the Federal Reserve; as a result, the Federal Reserve is the Bank’s primary federal regulator. As a member bank, the Bank must buy and hold stock in its district Federal Reserve Bank equal to 6% of the Bank’s capital stock and surplus. The Bank is paid a dividend on its investment at a rate which varies with ten-year U.S. Treasury rates, capped at 6%. The Bank cannot sell its investment in Federal Reserve Bank stock, and the investment provides the Bank with no control over the Federal Reserve System.
Tennessee law requires the Bank, as a member of the Federal Reserve, to comply with federal capital and many other regulatory requirements in lieu of, or sometimes in addition to, state requirements. For that reason, this “Supervision and Regulation” section focuses on federal requirements for many topics related to the Bank, mentioning state requirements only where significant.
From 1864 until October 2019, the Bank was a national banking association subject to the regulation and supervision of, and to examination by, the Office of the Comptroller of the Currency. During October, 2019, the Bank converted from a national bank to a Tennessee state bank. Conversion did not significantly alter the scope of the Bank’s activities: Tennessee law generally allows a Tennessee state bank to take any action that a Tennessee-based national bank could take.
The Bank is insured by, and subject to regulation by, the FDIC and is subject to regulation in certain respects by the CFPB. The Bank is also subject to various requirements and restrictions under federal and state law, including requirements to maintain reserves against deposits, restrictions on the types and amounts of loans that may be made and the interest that may be charged, limitations on the types of investments that may be made, activities that may be engaged in, and types of services that may be offered. Various consumer laws and regulations also affect the operations of the Bank. In addition, several of the Bank’s subsidiaries are regulated separately, as discussed in “Subsidiaries” beginning on page 8 of this report.
In addition to the impact of regulation, commercial banks are affected significantly by the actions of the Federal Reserve as it attempts to control money supply and credit availability in order to influence the economy. Also, the Bank and certain of its subsidiaries are prohibited from engaging in certain tie-in arrangements in connection with extensions of credit, leases or sales of property, or furnishing products or services.
The regulatory framework governing banks and the financial industry is intended primarily for the protection of depositors and the Federal Deposit Insurance Fund, not for the protection of our Bank or our security holders.
Regulatory Tiers Based on Asset Size
Many rules dealing with critical regulatory topics divide banks into tiers based largely or entirely on asset size. Different topics have different cut-off points for the tiers. Within each topic, different rules apply to the different tiers.
Cut-off points vary significantly. However, as a rough generalization, for many regulatory topics the critical cut-off points are $10 billion, $100 billion, and $250 billion. Companies with less than $10 billion are less regulated in several important ways than we are, and companies with $250 billion or more are regulated much more severely in many important ways than we are. As a result, under
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 9

current law, compliance costs and restrictions grow with size, they tend to change abruptly as a company crosses to the next tier, and we are in a middle tier in many respects.
The remainder of this “Supervision and Regulation” discussion focuses on current rules which apply to FHN based on our current asset size.
Large-Bank Supervision Risk Categories
Federal regulators have established four risk-based categories for applying enhanced prudential standards (enhanced for larger banks). Category I applies to the global systemically important companies. Categories II, III, and IV apply (with certain exceptions) to institutions with total consolidated assets of at least $700 billion, $250 billion, and $100 billion, respectively. Currently, we and the Bank are below Category IV’s floor and therefore, generally, we are not subject to enhanced prudential standards. We expect that, immediately after closing the IBKC merger and 30-branch acquisition mentioned in this Item 1 above, we will continue to be below Category IV’s floor.
Payment of Dividends
FHN is a legal entity separate and distinct from the Bank and other subsidiaries. FHN’s principal source of cash flow, including cash flow to pay dividends on its stock or to pay principal (including premium, if any) and interest on debt securities, is dividends from the Bank. There are statutory and regulatory limitations on the payment of dividends by the Bank to FHN, as well as by FHN to its shareholders.
FHN
Under Tennessee corporate law, FHN is not permitted to pay cash dividends if, after giving effect to such payment, FHN would not be able to pay its debts as they become due in the usual course of business or its total assets would be less than the sum of its total liabilities plus any amounts needed to satisfy any preferential rights if we were dissolving. In addition, in deciding whether or not to declare a dividend of any particular size, our Board must consider our current and prospective capital, liquidity, and other needs, including the needs of the Bank which FHN is obligated to support.
The Bank
Under Tennessee corporate law, the Bank (like FHN, discussed above) may not pay a dividend if the Bank would not be able to pay its debts when due or if the Bank’s assets would be inadequate, in a dissolution, to pay liabilities and preferential rights. Similarly, the Bank’s Board must consider current and prospective needs in making a decision to declare a dividend.
In addition, in order to pay cash dividends, the Bank must obtain the prior approval of the Federal Reserve and the TDFI Commissioner if the total of all dividends declared by the Bank’s board of directors in any calendar year
exceeds the total of (i) the Bank’s retained net income for that year plus (ii) the Bank’s retained net income for the preceding two years, less certain required capital transfers, as applicable. Below that ceiling, approval generally is not required (but see “Other Factors Affecting Dividends” immediately following this discussion). Applying the applicable rules, at January 1, 2020, the Bank could legally declare cash dividends on the Bank's common or preferred stock totaling approximately $331.2 million without obtaining approval. The application of those restrictions to the Bank is discussed in more detail in the following sections, all of which is incorporated into this Item 1 by reference: under the caption “Liquidity Risk Management” in our 2019 MD&A (Item 7) beginning on page 90 of this report; and under the caption “Restrictions on dividends” in Note 12-Regulatory Capital and Restrictions of our 2019 Financial Statements (Item 8), beginning on page 164 of this report.
Other Factors Affecting Dividends
If, in the opinion of the Federal Reserve, FHN or the Bank is engaged in or is about to engage in an unsafe or unsound practice (which, depending on the financial condition of FHN or the Bank, could include the payment of dividends), the Federal Reserve may require FHN or the Bank to cease and desist from that practice. The federal banking agencies have indicated that paying dividends that deplete a depository institution’s or holding company’s capital base to an inadequate level would be an unsafe and unsound banking practice.
In addition, under the Federal Deposit Insurance Act, an FDIC-insured depository institution (such as the Bank) may not make any capital distributions, pay any management fees to its holding company, or pay any dividend if it is undercapitalized or if such payment would cause it to become undercapitalized.
The payment of cash dividends by FHN or by the Bank also may be affected or limited by other factors, such as the requirement to maintain adequate capital above regulatory guidelines and requirements imposed by debt covenants. For example, as discussed under “Capital Adequacy” starting on page 11, FHN's ability to pay dividends would be restricted if its capital ratios fell below minimum regulatory requirements plus a capital conservation buffer.
The Federal Reserve generally requires insured banks and bank holding companies to pay dividends only out of current operating earnings. The Federal Reserve has released a supervisory letter advising, among other things, that a bank holding company should inform the Federal Reserve and should eliminate, defer, or significantly reduce its dividends if (i) the bank holding company’s net income available to shareholders for the past four quarters, net of dividends previously paid during that period, is not sufficient to fully fund the dividends; (ii) the bank holding company’s prospective rate of earnings is not consistent with the bank holding company’s capital needs and overall
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 10

current and prospective financial condition; or (iii) the bank holding company will not meet, or is in danger of not meeting, its minimum regulatory capital adequacy ratios.
Transactions with Affiliates
The Bank’s ability to lend or extend credit to FHN and its nonbank subsidiaries (including for purposes of this paragraph, in certain situations, subsidiaries of the Bank) is restricted. The Bank and its subsidiaries generally may not extend credit to FHN or to any other affiliate in an amount which exceeds 10% of the Bank’s capital stock and surplus and may not extend credit in the aggregate to all such affiliates in an amount which exceeds 20% of its capital stock and surplus. Extensions of credit and other transactions between the Bank and FHN or such other affiliates must be on terms and under circumstances, including credit standards, that are substantially the same or at least as favorable to the Bank as those prevailing at the time for comparable transactions with non-affiliated companies. Further, the type, amount, and quality of collateral which must secure such extensions of credit is regulated.
There are similar legal restrictions on: the Bank’s purchases of or investments in the securities of and purchases of assets from FHN and its nonbank subsidiaries; the Bank’s loans or extensions of credit to third parties collateralized by the securities or obligations of FHN and its nonbank subsidiaries; the issuance of guaranties, acceptances, and letters of credit on behalf of FHN and its nonbank subsidiaries; and certain bank transactions with FHN and its nonbank subsidiaries, or with respect to which FHN and its nonbank subsidiaries act as agent, participate, or have a financial interest.
Capital Adequacy
Federal financial industry regulators require that regulated institutions maintain minimum capital levels. The capital rules in the U.S. are based on international standards known as “Basel III.” Those standards require the following:

• | Common Equity Tier 1 Capital Ratio. For all supervised financial institutions, including FHN and the Bank, the ratio of Common Equity Tier 1 Capital to risk-weighted assets (“Common Equity Tier 1 Capital ratio”) must be at least 4.5%. To be “well capitalized” the Common Equity Tier 1 Capital ratio must be at least 6.5%. Common Equity Tier 1 Capital consists of core components of Tier 1 Capital. The core components consist of common stock plus retained earnings net of goodwill, other intangible assets, and certain other required deduction items. At December 31, 2019, FHN’s Common Equity Tier 1 Capital Ratio was 9.20% and the Bank’s was 9.38%.

• | Tier 1 Capital Ratio. For all supervised financial institutions, including FHN and the Bank, the ratio of Tier 1 Capital to risk-weighted assets must be at least

6%. To be “well capitalized” the Tier 1 Capital ratio must be at least 8%. Tier 1 Capital consists of the Tier 1 core components discussed in the bulleted paragraph immediately above, plus non-cumulative perpetual preferred stock, a limited amount of minority interests in the equity accounts of consolidated subsidiaries, and a limited amount of cumulative perpetual preferred stock, net of goodwill, other intangible assets, and certain other required deduction items. At December 31, 2019, FHN’s Tier 1 Capital Ratio was 10.15% and the Bank’s was 10.18%.

• | Total Capital Ratio. For all supervised financial institutions, including FHN and the Bank, the ratio of Total Capital to risk-weighted assets must be at least 8%. To be “well capitalized” the Total Capital ratios must be at least 10%. At December 31, 2019, FHN’s Total Capital Ratio was 11.22% and the Bank’s was 10.77%.

• | Capital Conservation Buffer. If a capital conservation buffer of an additional 2.5% above the minimum required Common Equity Tier 1 Capital ratio, Tier 1 Capital ratio, and Total Capital ratio is not maintained, special restrictions would apply to capital distributions, such as dividends and stock repurchases, and on certain compensatory bonuses.

• | Leverage Ratio-Base. For all supervised financial institutions, including FHN or the Bank, the Leverage ratio must be at least 4%. To be “well capitalized” the Leverage ratio must be at least 5%. The Leverage ratio is Tier 1 Capital divided by quarterly average assets net of goodwill, certain other intangible assets, and certain required deduction items. At December 31, 2019, FHN’s Leverage ratio was 9.04% and the Bank’s was 9.12%.

• | Leverage Ratio-Supplemental. For the largest internationally active supervised financial institutions, not including FHN or the Bank, a minimum supplementary Leverage ratio must be maintained that takes into account certain off-balance sheet exposures.

• | Liquidity Coverage Ratio. This requirement does not apply to institutions with assets of less than $100 billion, and so does not apply to FHN or the Bank. For larger institutions, the requirement applies based on which Category a bank is in. Categories IV, III, and II apply to banks with $100 billion, $250 billion, and $750 billion, respectively, subject to several exceptions based on certain holdings, activities, or exposures. Category I includes systemically important institutions.

FHN believes that both FHN and the Bank were in compliance with applicable minimum capital requirements as of December 31, 2019.
Federal regulators have incorporated market and interest-rate risk components into its risk-based capital standards. Those standards explicitly identify concentration of credit risk and certain risks arising from non-traditional activities, and the management of such risks, as important qualitative
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 11

factors to consider in assessing an institution’s overall capital adequacy.
Federal regulators’ market risk rules are applicable to covered institutions-those with aggregate trading assets and trading liabilities of at least 10% of their total assets or at least $1 billion. FHN and the Bank are covered institutions under the rule. The rules specify the methodology for calculating the amount of risk-weighted assets related to trading assets and include, among other things, the addition of a component for stressed value at risk. The rule eliminates the use of credit ratings in calculating specific risk capital requirements for certain debt and securitization positions. Alternative standards of creditworthiness are used for specific standardized risks, such as exposures to sovereign debt, public sector entities, other banking institutions, corporate debt, and securitizations. In addition, an 8% capital surcharge applies to certain covered institutions, not including FHN or the Bank.
Moreover, the Federal Reserve has indicated that it considers a “Tangible Tier 1 Capital Leverage Ratio” (deducting all intangibles) and other indicia of capital strength in evaluating proposals for expansion or new activities.
Failure to meet capital guidelines could subject a bank to a variety of enforcement remedies, including the termination of deposit insurance by the FDIC, and to certain restrictions on its business and in certain circumstances to the appointment of a conservator or receiver. See “Prompt Corrective Action (PCA)” immediately below for additional information.
In addition, the Bank is required to have a capital structure that the TDFI determines is adequate, based on TDFI’s assessment of the Bank’s businesses and risks. The TDFI may require the Bank to increase its capital, if found to be inadequate.
Prompt Corrective Action (PCA)
Federal banking regulators must take “prompt corrective action” regarding FDIC-insured depository institutions that do not meet minimum capital requirements. For this purpose, insured depository institutions are divided into five capital categories. The specific requirements applicable to us are summarized in the following table.
REQUIREMENTS FOR PCA CAPITALIZATION CATEGORIES

Well capitalized | Common Equity Tier 1 Capital ratio of at least 6.5% Tier 1 Capital ratio of at least 8% Total Capital ratio of at least 10% Leverage ratio of at least 5% Not subject to a directive, order, or written agreement to meet and maintain specific capital levels
Adequately capitalized | Common Equity Tier 1 Capital ratio of at least 4.5% Tier 1 Capital ratio of at least 6% Total Capital ratio of at least 8% Leverage ratio of at least 4% Not subject to a directive, order, or written agreement to meet and maintain specific capital levels
Undercapitalized | Failure to maintain any requirement to be adequately capitalized
Significantly Undercapitalized | Failure to maintain Common Equity Tier 1 Capital ratio of at least 3%, Tier 1 Capital ratio of at least 4%, Total Capital ratio of at least 6%, or a Leverage ratio of at least 3%
Critically Undercapitalized | Failure to maintain a level of tangible equity equal to at least 2% of total assets

At December 31, 2019, the Bank had sufficient capital to qualify as “well capitalized” under the regulatory capital requirements discussed above. An institution may be deemed to be in a capitalization category that is lower than is indicated by its actual capital position if it receives an unsatisfactory examination rating. Institutions generally are not allowed to publicly disclose examination results.
An FDIC-insured depository institution generally is prohibited from making any capital distribution (including payment of dividends) or paying any management fee to its
holding company if the depository institution would thereafter be undercapitalized. Undercapitalized depository institutions are subject to restrictions on borrowing from the Federal Reserve System. In addition, undercapitalized depository institutions are subject to growth limitations and are required to submit capital restoration plans. An insured depository institution’s holding company must guarantee the capital plan, up to an amount equal to the lesser of 5% of the depository institution’s assets at the time it becomes undercapitalized or the amount of the capital deficiency when the institution fails to comply with the plan, for the
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 12

plan to be accepted by the applicable federal regulatory authority. The federal banking agencies may not accept a capital plan without determining, among other things, that the plan is based on realistic assumptions and is likely to succeed in restoring the depository institution’s capital. If a depository institution fails to submit an acceptable plan, it is treated as if it were significantly undercapitalized.
Significantly undercapitalized depository institutions may be subject to a number of requirements and restrictions, including orders to sell sufficient voting stock to become adequately capitalized, requirements to reduce total assets and cessation of receipt of deposits from correspondent banks.
Critically undercapitalized depository institutions are subject to appointment of a receiver or conservator, generally within 90 days of the date on which they become critically undercapitalized.
Holding Company Structure and Support of Subsidiary Banks
Because FHN is a holding company, its right to participate in the assets of any subsidiary upon the latter’s liquidation or reorganization will be subject to the prior claims of the subsidiary’s creditors (including depositors in the case of the Bank) except to the extent that FHN may itself be a creditor with recognized claims against the subsidiary. In addition, depositors of a bank, and the FDIC as their subrogee, would be entitled to priority over the creditors in the event of liquidation of a bank subsidiary.
Under Federal Reserve policy FHN is expected to act as a source of financial strength to, and to commit resources to support, the Bank. This support may be required at times even though, absent such Federal Reserve policy, FHN might not wish to provide it. In addition, any capital loans by a bank holding company to any of its subsidiary banks are subordinate in right of payment to deposits and to certain other indebtedness of the subsidiary bank. In the event of a bank holding company’s bankruptcy, any commitment by the bank holding company to a federal bank regulatory agency to maintain the capital of a subsidiary bank will be assumed by the bankruptcy trustee and entitled to a priority of payment.
Cross-Guarantee Liability
A depository institution insured by the FDIC can be held liable for any loss incurred by, or reasonably expected to be incurred by, the FDIC in connection with (i) the default of a commonly controlled FDIC-insured depository institution or (ii) any assistance provided by the FDIC to any commonly controlled FDIC-insured depository institution “in danger of default.” “Default” is defined generally as the appointment of a conservator or receiver and “in danger of default” is defined generally as the existence of certain conditions indicating that a default is likely to occur in the absence of regulatory assistance. The FDIC’s claim for damages is superior to claims of
shareholders of the insured depository institution or its holding company but is subordinate to claims of depositors, secured creditors, and holders of subordinated debt (other than affiliates) of the commonly controlled insured depository institution.
Currently the Bank is the only depository institution owned by FHN. If FHN were to operate another depository institution, any loss suffered by the FDIC in respect of one subsidiary bank would likely result in assertion of the cross-guarantee provisions, the assessment of such estimated losses against FHN’s other subsidiary bank(s), and a potential loss of FHN’s investment in its subsidiary banks.
Interstate Branching and Mergers
As mentioned above, the Bank generally must have TDFI’s approval to establish a new banking center (technically, a “branch”). For a new banking center located outside of Tennessee, Tennessee law requires the Bank to comply with branching laws applicable to the state where the new banking center will be located. Federal law allows the Bank to establish or acquire a branch in another state to the same extent as a bank chartered in that other state would be allowed to establish or acquire a branch in Tennessee.
For an interstate merger or acquisition: the acquiring bank must be well-capitalized and well-managed; concentration limits on liabilities and deposits may not be exceeded; regulators must assess the transaction for incremental systemic risk; and the acquiring bank must have at least “satisfactory” standing under the federal Community Reinvestment Act (discussed immediately below).
Once a bank has established branches in a state through de novo or acquired branching or through an interstate merger transaction, the bank may then establish or acquire additional branches within that state to the same extent that a bank chartered in that state is allowed to establish or acquire branches within the state.
Community Reinvestment Act (“CRA”)
The CRA requires each U.S. bank, consistent with safe and sound operation, to help meet the credit needs of each community where the bank accepts deposits, including low- and moderate-income (“LMI”) communities. The Federal Reserve assesses the Bank periodically for CRA compliance, and that assessment is made public. The Bank’s LMI operations and activities generally are critical focal points in those assessments. The next CRA assessment is expected in 2020 or 2021.
A CRA rating below “satisfactory” can slow or halt a bank’s plans to expand by branching, acquisition, or merger, and can prevent a bank holding company from becoming a financial holding company. The Bank received a rating of “Satisfactory” in its most recent CRA assessment, issued in 2017.
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 13

Late in 2019, certain federal regulatory agencies proposed changes to their regulations under the CRA. Although highly technical, the proposal prompted several federal legislators to submit letters in opposition. The Federal Reserve did not join the proposal, so technically the proposal does not apply to FHN or the Bank. However, this proposal could lead to some type of CRA regulatory reform that the Federal Reserve does join or, possibly, legislation amending the CRA.
Financial Activities other than Banking
Federal Law
Federal law generally allows financial holding companies broad authority to engage in activities that are financial in nature or incidental to a financial activity. These include: insurance underwriting and brokerage; merchant banking; securities underwriting, dealing, and market-making; real estate development; and such additional activities as the Federal Reserve in consultation with the Secretary of the Treasury determines to be financial in nature or incidental. A bank holding company may engage in these activities directly or through subsidiaries by qualifying as a “financial holding company.” To qualify as a financial holding company, a bank holding company must file an initial declaration with the Federal Reserve, certifying that all of its subsidiary depository institutions are well-managed and well-capitalized.
Federal law also permits banks to engage in certain of these activities through financial subsidiaries. To control or hold an interest in a financial subsidiary, a bank must meet the following requirements:

(1) | The bank must receive approval from its primary federal regulator for the financial subsidiary to engage in the activities.

(2) | The bank and its depository institution affiliates must each be well-capitalized and well-managed.

(3) | The aggregate consolidated total assets of all of the bank’s financial subsidiaries must not exceed the lesser of: 45% of the bank’s consolidated total assets; or $50 billion (subject to indexing for inflation).

(4) | The bank must have in place adequate policies and procedures to identify and manage financial and operational risks and to preserve the separate identities and limited liability of the bank and the financial subsidiary.

(5) | If the bank is one of the one hundred largest banks, the bank must meet the long-term debt rating or alternative standards adopted by the Federal Reserve and the U.S. Secretary of the Treasury from time to time. If this fifth requirement ceases to be met after a bank controls or holds an interest in a financial subsidiary, the bank cannot invest additional capital in that subsidiary until the requirement again is met.

No new activity may be commenced unless the bank and all of its depository institution affiliates have at least “satisfactory” Community Reinvestment Act ratings. Certain restrictions apply if the bank holding company or the bank fails to continue to meet one or more of the requirements listed above.
In addition, federal law contains a number of other provisions that may affect the Bank’s operations, including limitations on the use and disclosure to third parties of customer information.
At December 31, 2019, FHN is a financial holding company and the Bank has a number of financial subsidiaries, as discussed in “Subsidiaries” beginning on page 8 of this report.
Tennessee Law
Tennessee law does not expressly restrict the activities of a bank holding company or its non-bank affiliates. However, no Tennessee bank may maintain a branch office on the premises of an affiliate if the affiliate is engaged in activities that are not permissible for a bank holding company, a financial holding company, a national bank, or a national bank subsidiary under federal law. Tennessee law permits Tennessee banks to establish subsidiaries and to engage in any activities permissible for a national bank located in Tennessee, subject to compliance with Tennessee regulations relating to the conduct of such activities for the purpose of maintaining bank safety and soundness.
Interchange Fee Restrictions
Regulations severely cap interchange fees which the Bank may charge merchants for debit card transactions.
Volcker Rule
The Volcker rule (1) generally prohibits banks from engaging in proprietary trading, which is engaging as principal (for the bank’s own account) in any purchase or sale of one or more of certain types of financial instruments, and (2) limits banks’ ability to invest in or sponsor hedge funds or private equity funds.
Consumer Regulation by the CFPB
The CFPB adopts and administers significant rules affecting consumer lending and consumer financial services. Key rules for the Bank include detailed regulation of mortgage servicing practices and detailed regulation of mortgage origination and underwriting practices. The latter rules, among other things, establish the definition of a “qualified mortgage” using traditional underwriting practices involving down payments, credit history, income levels and verification, and so forth. The rules do not prohibit, but do tend to discourage, lenders from originating non-qualified mortgages.
Data Privacy & Security
Federal law restricts the Bank’s ability to share certain information with affiliates and non-affiliates for marketing
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 14

and/or non-marketing purposes, or to contact customers with marketing offers. Federal law also requires banks to implement a comprehensive information security program that includes administrative, technical and physical safeguards.
Data privacy and protection increasingly is a significant legislative, regulatory, and societal concern. The concern is driven by major technological and societal shifts in the past 20 years, led by relatively unregulated firms such as Amazon.com, Alibaba, Facebook, and Google and their many customers worldwide. Those firms have gathered large amounts of personal details about millions of people, and today have the ability to analyze that data and act on that analysis very quickly. These firms seek to understand enough about a person to know what a person wants before the person does.
Banks (as mentioned above) already are subject to significant privacy regulations. Probably for that reason, the banking industry is not at the political center of these concerns today. Even so, banks are likely to be affected by broader legislative and regulatory responses to the perceived problems. Two prominent responses to date include the European Union General Data Protection Regulation and the California Data Privacy Protection Act. Neither is a banking industry regulation, but both apply to banks in relation to certain customers. To date, neither has had a material impact on the Bank.
FDIC Insurance Assessments; DIFA
U.S. bank deposits generally are insured by the Deposit Insurance Fund (“DIF”). The system of FDIC insurance premium rates charged consists of a rate grid structure in which base rates range from 5 to 35 basis points annually, and fully adjusted rates range from 2.5 to 45 basis points annually. Key factors in the grid include: the institution’s risk category (I to IV); whether the institution is deemed large and highly complex; whether the institution qualifies for an unsecured debt adjustment; and whether the institution is burdened with a brokered deposit adjustment. Other factors can impact the base against which the applicable rate is applied, including (for example) whether a net loss is realized. A basis point is equal to 0.01%.
Insurance of deposits may be terminated by the FDIC upon a finding that the institution has engaged in unsafe and unsound practices, is in an unsafe or unsound condition to continue operations, or has violated any applicable law, regulation, rule, order, or condition imposed by a federal bank regulatory agency.
Depositor Preference
Federal law provides that deposits and certain claims for administrative expenses and employee compensation against an insured depository institution would be afforded a priority over other general unsecured claims against such an institution, including federal funds and letters of credit,
in the “liquidation or other resolution” of such an institution by any receiver.
Securities Regulation
Certain of our subsidiaries are subject to various securities laws and regulations and capital adequacy requirements promulgated by the regulatory and exchange authorities of the jurisdictions in which they operate.
Our registered broker-dealer subsidiaries are subject to the SEC’s net capital rule, Rule 15c3-1. That rule requires the maintenance of minimum net capital and limits the ability of the broker-dealer to transfer large amounts of capital to a parent company or affiliate. Compliance with the rule could limit operations that require intensive use of capital, such as underwriting and trading.
Certain of our subsidiaries are registered investment advisers which are regulated under the Investment Advisers Act of 1940. Advisory contracts with clients automatically terminate under these laws upon an assignment of the contract by the investment adviser unless appropriate consents are obtained.
Insurance Activities
Certain subsidiaries sell various types of insurance as agent in a number of states. Insurance activities are subject to regulation by the states in which such business is transacted. Although most of such regulation focuses on insurance companies and their insurance products, insurance agents and their activities are also subject to regulation by the states, including, among other things, licensing and marketing and sales practices.
Compensation and Risk Management
The Federal Reserve has issued guidance intended to ensure that incentive compensation arrangements at financial organizations take into account risk and are consistent with safe and sound practices. The guidance is based on three “key principles” calling for incentive compensation plans to: appropriately balance risks and rewards; be compatible with effective controls and risk management; and be backed up by strong corporate governance. In response: we operate an enhanced risk management process for assessing risk in incentive compensation plans; several key incentive programs use a net profit approach rather than a revenues-only approach; and mandatory deferral features are used in several key programs, including an executive program.
In 2016 federal agencies proposed regulations which could significantly change the regulation of incentive compensation programs at financial institutions. The proposal would create four tiers of institutions based on asset size. Institutions in the top two tiers would be subject to rules much more detailed and proscriptive than are currently in effect. If interpreted aggressively by the regulators, the proposed rules could be used to prevent, as a practical matter, larger institutions from engaging in
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 15

certain lines of business where substantial commission and bonus pool arrangements are the norm. In the 2016 proposal, the top two tiers included institutions with more than $50 billion of assets. FHN and the Bank currently would fall into the third tier, where the impact of the proposed rules would be substantially more modest, and would move up to the second tier after the IBKC merger
closes. However, prompted by post-2016 legislation which significantly raised several statutory asset-size tiers, if this proposal were finalized now, the $50 billion floor might be raised significantly, allowing FHN to remain in the third tier. FHN cannot predict what final rules may be adopted, nor how they will be implemented.

Effect of Governmental Policies

The Bank is affected by the policies of regulatory authorities, including the Federal Reserve, the TDFI, and the CFPB. The Federal Reserve also sets and manages monetary policy for the U.S. In this latter role, the Federal Reserve’s mandate from Congress is to pursue price stability and full employment.
Among the instruments of monetary policy used by the Federal Reserve are: purchases and sales of U.S. government and other securities in the marketplace; changes in the discount rate, which is the rate any depository institution must pay to borrow from the Federal Reserve; changes in the reserve requirements of depository institutions; changes in the rate paid on banks’ required and excess reserve deposits at the Federal Reserve; and changes in the federal funds rate, which is the rate at which depository institutions lend balances to each other overnight. These instruments are intended to influence
economic and monetary growth, interest rate levels, and inflation.
The monetary policies of the Federal Reserve and other governmental policies have had a significant effect on the operating results of commercial banks in the past and are expected to continue to do so in the future. Because of changing conditions in the national and international economies and in the money markets, as well as the result of actions by monetary and fiscal authorities, it is not possible to predict with certainty future changes in interest rates, deposit levels, loan demand, or the business and results of operations of FHN and the Bank, or whether changing economic conditions will have a positive or negative effect on operations and earnings.

Other Proposals

Bills occasionally are introduced in the United States Congress and the Tennessee General Assembly and other state legislatures, and regulations occasionally are proposed by our regulatory agencies, any of which could affect our businesses, financial results, and financial condition.
We are not able to predict what, if any, changes that Congress, state legislatures, or the regulatory agencies will enact or implement in the future, nor the impact that those actions will have upon us.

Competition

In all aspects of the businesses in which we engage, we face substantial competition from banks doing business in our markets as well as from savings and loan associations, credit unions, other financial institutions, consumer finance companies, trust companies, investment counseling firms, money market and other mutual funds, insurance companies and agencies, securities firms, mortgage banking companies, hedge funds, and other firms offering financial products or services.
Regional Banking
Our regional banking business primarily competes in several areas within the southeast U.S. where we have banking center locations. However, competition in our industry is trending away from the traditional geographic
footprint model. That trend is happening throughout the industry, but the rate of change is highly uneven among different types of customers, products, and services.
Our regional banking business serves both consumer and commercial customers. The consumer business remains strongly linked to our physical banking center locations, even as our delivery of financial services to consumers becomes increasingly focused on popular non-physical delivery methods, such as online and mobile banking. Online and mobile banking have contributed to a decline in banking center usage, but not (so far) an erosion of the link between banking center versus consumer customer location. Increasingly, however, consumers are able to manage their funds and financial affairs at multiple
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 16

financial institutions through only one of them. If cross- institutional management features become popular, they may hasten a de-linking of consumers to traditional banking center networks.
The commercial business also has a geographic linkage, but it is weaker. Some areas of our commercial banking business, particularly in specialty lending, are broadly regional or even national in scope rather than being heavily centered on banking center locations.
Key traditional competitors in many of our markets include Wells Fargo Bank N.A., Bank of America N.A., First-Citizens Bank & Trust Company (dba First Citizens Bank), Pinnacle Bank (headquartered in Tennessee), Synovus Bank, Truist Bank, and Regions Bank, among many others including many community banks and credit unions. Additional key competitors in south Florida are JPMorgan Chase Bank National Association, PNC Bank National Association, and BankUnited.
A number of recent technologies created or operated by non-banks have been integrated into the financial systems used by traditional banks, such as the evolution of ATM cards into debit/credit cards and the evolution of debit/credit cards into smart phones. These sorts of incrementally evolutionary technologies often have expanded the market for banking services overall while siphoning a portion of the revenues from those services away from banks. Prior methods of delivering those services were disrupted, but often at a pace which all but the weakest banks could accommodate.
Recently, some evolutionary pressures have arisen which may prove to be less incremental and more disruptive. For example, in financial planning and wealth management, companies that are not traditional banks, including both long-established firms (such as Vanguard) and new ones (such as Betterment), have developed highly-interactive systems and applications. These services compete directly with traditional banks in offering personal financial advice. The low-cost, high-speed nature of these “robo-advisor” services can be especially attractive to younger, less-
affluent customers and potential customers. We and other traditional banks offer similar services, but doing so risks cannibalizing traditional business models for these services.
In recent years, certain financial companies or their affiliates that traditionally were not banks have been able to compete more directly with the Bank for deposits and other traditional banking services and products. Increased fluidity across traditional boundaries is likely to continue. Non-traditional companies competing with us for traditional banking products and services include investment banks, brokerage firms, insurance company affiliates, peer-to-peer lending arrangers, non-bank deposit acceptors, companies offering payment facilitation services (such as PayPal and pre-paid debit card issuers), and extremely short-term consumer loan companies.
Fixed Income
Our fixed income business serves institutional customers, broadly segregated into depositories (including banks, thrifts, and credit unions) and non-depositories (including money managers, insurance companies, governmental units and agencies, public funds, pension funds, and hedge funds). Both customer segments are widely dispersed geographically, predominantly within the U.S. We have many competitors within both segments including major U.S. and international securities firms as well as numerous regional and local firms.
Additional Information
For additional information on the competitive position of FHN and the Bank, refer to the “General” subsection above of this Item 1. Also, refer to the subsections entitled “Supervision and Regulation” and “Effect of Governmental Policies,” both of which are relevant to an analysis of our competitors. Due to the intense competition in the financial services industry we can make no representation that our competitive position has or will remain constant, nor can we predict how it may change in the future.

ITEM 1A. RISK FACTORS
----------------
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 19

This Item outlines specific risks that could affect the ability of our various businesses to compete, change our risk profile, or materially impact our operating results or financial condition. Our operating environment continues to evolve and new risks continue to emerge. To address that challenge we have a risk management governance structure that oversees processes for monitoring evolving risks and oversees various initiatives designed to manage and control our potential exposure.
This Item highlights risks that could impact us in material ways by causing future results to differ materially from past results, by causing future results to differ materially from current expectations, or by causing material changes in our financial condition. In this Item we have outlined risks that we believe are important to us at the present time. However, other risks may prove to be important in the future, and new risks may emerge at any time. We cannot predict all potential developments that could materially affect our financial performance or condition.

Traditional Competition Risks

We are subject to intense competition for customers, and the nature of that competition is changing quickly. Our primary areas of competition for customers include: consumer and commercial deposits, commercial loans, consumer loans including home mortgages and lines of credit, financial planning and wealth management, fixed income products and services, and other consumer and commercial financial products and services. Our competitors in these areas include national, state, and non-US banks, savings and loan associations, credit unions, consumer finance companies, trust companies, investment counseling firms, money market and other mutual funds, insurance companies and agencies, securities firms, mortgage banking companies, hedge funds, and other financial services companies (traditional and otherwise) that serve the markets which we serve. The emergence of non-traditional, disruptive service providers (see “Industry Disruption” beginning on page 22) has intensified the competitive environment.
Some competitors are traditional banks, subject to the same regulatory framework as we are, while others are not banks and in many cases experience a significantly different or reduced degree of regulation. Long-standing examples of less-regulated activity include check-cashing and
independent ATM services. A recent example of unregulated activity is so-called “peer-to-peer” lending, where investors provide debt financing and/or capital directly to borrowers.
We expect that competition will continue to grow more intense with respect to most of our products and services. Heightened competition tends to put downward pressure on revenues from affected items, upward pressure on marketing and other promotional costs, or both. For additional information regarding competition for customers, refer to “Competition” within Item 1 beginning on page 16 of this report.
We compete for talent. Our most significant competitors for customers also are our most significant competitors for top talent. See “Operational Risks” beginning on page 23 of this Item 1A for additional information concerning this risk.
We compete to raise capital in the equity and debt markets. See “Liquidity and Funding Risks” beginning on page 32 of this Item 1A for additional information concerning this risk.

Traditional Strategic and Macro Risks

We may be unable to successfully implement our strategy to grow our commercial and consumer banking businesses and our fixed income business. Although our current strategy is expected to evolve as business conditions change, at present our strategy is primarily to invest resources in our banking and fixed income businesses. Growth is expected to be coordinated
with a focus on strong and stable returns on capital. In the past four years we have mixed organic growth with tactical acquisitions and a strategic acquisition (Capital Bank). In 2020 we expect to close a tactical acquisition of 30 bank branches and a strategic merger-of-equals with IBKC.
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 21

Organically, we have enhanced our market share in our traditional banking markets with targeted hires and marketing, expanded into other southeast U.S. markets with similar characteristics, and expanded with commercial lending and private client banking in the Houston, Texas market. We have made similar moves in our fixed income business.
In the future, we expect to continue to nurture profitable organic growth, especially after we combine and integrate the 30 branches and IBKC with our existing banking centers and operations. We may pursue other acquisitions if appropriate opportunities, within or outside of our current markets, present themselves.
Failure to achieve one or more key elements needed for successful organic growth would adversely affect our business and earnings. We believe that the successful execution of organic growth depends upon a number of key elements, including:

• | our ability to attract and retain customers in our banking market areas;

• | our ability to achieve and maintain growth in our earnings while pursuing new business opportunities;

• | in our fixed income business, our ability to maintain or strengthen our existing customer relationships while at the same time identifying and successfully executing upon opportunities to provide new or existing products and services to new or existing customers;

• | our ability to maintain a high level of customer service while optimizing our physical banking center count due to changing customer demand, all while expanding our remote banking services and expanding or enhancing our information processing, technology, compliance, and other operational infrastructures effectively and efficiently;

• | our ability to manage the liquidity and capital requirements associated with growth, especially organic growth and cash-funded acquisitions; and

• | our ability to manage effectively and efficiently the changes and adaptations necessitated by a complex, burdensome, and evolving regulatory environment.

We have in place strategies designed to achieve those elements that are significant to us at present. Our challenge is to execute those strategies and adjust them, or adopt new strategies, as conditions change.
Failure to achieve one or more key elements needed for successful business acquisitions would adversely affect our business and earnings. To the extent we engage in bank or non-bank business acquisitions (including the two currently pending), we face various additional risks, including:

• | our ability to realize planned or hoped-for strategic and tactical objectives, including operating efficiencies

and revenue synergies, within a reasonable time period after closing the transaction;

• | our ability to identify, analyze, and correctly assess the execution, credit, contingency, and other risks in the acquisition and to price the transaction appropriately;

• | our ability to properly evaluate loss inherent in the target business’ loan portfolios;

• | our ability to integrate the acquired business’ operations, customers, and properties quickly and cost-effectively;

• | our ability to manage cultural assimilation risks associated with growth through acquisitions, which can be an often-overlooked and often-critical failure point in mergers;

• | our ability to combine the franchise values of the two companies without significant loss from re-branding and other similar changes; and

• | our ability to retain core customers and key employees.

In fourth quarter 2019, we re-branded our businesses and began re-branding our banking centers. That effort makes us somewhat more sensitive, for a time, to the risk that customers will experience confusion or “branding fatigue,” which may be exacerbated in 2020 when we complete the re-branding of our banking centers, convert the 30 acquired branches, and begin to convert IBKC businesses and locations to the First Horizon brands. Fortunately, some of the 30 branches, and most of IBKC’s branches, do not overlap with our banking center markets, which should help mitigate ill effects.
A type of strategic acquisition-a so-called “merger of equals” where the company we nominally acquire has similar size, operating contribution, or value-presents unique opportunities but also unique risks. Those special risks, which are present in the IBKC transaction, include:

• | the potential for elevated and duplicative operating expenses if we are unable to integrate the two companies efficiently in a reasonable amount of time; and

• | the potential for a significant increase in the time horizon that may be needed before substantial economies of scale can be realized or substantial revenue synergies can be developed effectively.

FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 22

Industry Disruption

Through technological innovations and changes in customer habits, the manner in which customers use financial services continues to change at a rapid pace. We provide a large number of services remotely (online and mobile), and physical banking center utilization has been in long-term decline throughout the industry for many years. Technology has helped us reduce costs and improve service, but also has weakened traditional geographic and relationship ties, and has allowed disruptors to enter traditional banking areas.
Through digital marketing and service platforms, many banks are making customer inroads unrelated to physical presence. This competitive risk is especially pronounced from the largest U.S. banks, and from online-only banks, due in part to the investments they are able to sustain in their digital platforms.
Companies as disparate as PayPal (an online payment clearinghouse) and Starbucks (a large chain of cafes) provide payment and exchange services which compete directly with banks in ways not possible traditionally.
The nature of technology-driven disruption to our industry is changing, in some cases seeking to displace traditional financial service providers rather than merely enhance traditional services or their delivery. A number of recent technologies have worked with the existing financial system and traditional banks, such as the evolution of ATM cards into debit/credit cards and the evolution of debit/credit cards into smart phones. These sorts of technologies often have expanded the market for banking services overall while siphoning a portion of the revenues from those services away from banks and disrupting prior methods of delivering those services. But some recent innovations may tend to replace traditional banks as financial service providers rather than merely augment those services.
For example, companies which claim to offer applications and services based on artificial intelligence are beginning to compete much more directly with traditional financial services companies in areas involving personal advice, including high-margin services such as financial planning and wealth management. The low-cost, high-speed nature of these “robo-advisor” services can be especially attractive to younger, less-affluent customers and potential customers, as well as persons interested in “self-service” investment management. Other industry changes, such as zero-commission trading offered by certain large firms able to use trading as a loss-leader, may amplify this trend.
Similarly, inventions based on blockchain technology eventually may be the foundation for greatly enhancing transactional security throughout the banking industry, but also eventually may greatly reduce the need for banks as financial deposit-keepers and intermediaries.
We believe that, over the course of the technology-driven evolution of our industry which is well underway, the “winners” will be those institutions which can know their customers and make those customers feel they are known, even when many customers increasingly do not visit banking centers or have face-to-face live interaction. Two keys to achieving a psychological connection with such customers are (1) data management and analytics, using artificial intelligence processes, which allow an institution to provide a differentiated, personalized experience for the customer at the point of interaction, and (2) seamless integration of real-time customer contact with a human being through voice, chat, or otherwise.
A critical factor in successful data analytics, allowing real-time differentiated interaction with customers, is how traditionally uncaptured, unstructured, or siloed data is acquired, managed, and accessed. Some banks are experimenting with different methods of addressing this business need, and more will follow. In addition, external vendors are developing processes to provide solutions. A basic challenge for all these efforts is how to integrate analysis of extremely disparate forms of data and utilize that analysis in each customer contact in a manner which most customers not only accept, but value.
Developing workable proprietary solutions to the data analytics challenges ahead of competitors requires substantial investment in information technology systems and innovation. Even with a substantial IT budget, we cannot outspend, or even come close to matching, the largest U.S. banking institutions. Therefore, like most U.S. banks, our strategy must be focused on leveraging products and solutions which are within our means, including those developed by external vendors. Our goal must be to keep pace with industry developments with a focus on improving the customer’s differentiated experience with us by recognizing and responding to customer needs.
Technological innovation has tended to reduce barriers to entry based on cost. Put another way, once someone finds a new, better method to accomplish a task in our industry, often others are able to replicate or improve on that method, sometimes quite rapidly. Key risks for us, therefore, are whether we will be able: to catch up to breakthroughs quickly enough to avoid customer attrition; to adopt and enhance breakthroughs frequently enough, and without significant technical failures, to attract customers from competitors; and, if we are able to truly innovate, to press our advantage quickly before competitors adopt it.
To thrive as our industry is disrupted, we will need to embrace some of the attitudes of a technology company,
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 23

and shed some of the attitudes of a traditional bank. This has and will continue to require an evolution in our corporate culture which, in turn, creates implementation risk. In this process it is critical that we not lose sight of how our customers experience working with us and our systems, including those customers who still want traditionally-delivered services, those who seek and embrace the latest innovations, and those who just want services to be convenient, personalized, and understandable.
Just as disruptive business changes driven by new technologies and new customer preferences can adversely impact us and our entire industry, similar events can adversely impact our commercial customers.
In time, a major business disruption can cause dominant businesses to fail, and can shrink or even end entire lines of business. An example of this is the business failure of the Blockbuster video distribution chain and most other video distribution stores, and the rise of Netflix. Many other examples of this kind of process are ongoing today in many industries, including publishing, retail sales, news, and the creation as well as distribution of audio and video entertainment. To the extent disruptions impact our customers, we may experience elevated loan losses and loss of ongoing business which we may not be able to recapture with new customers.

Operational Risks

Fraud is a major, and increasing, operational risk for us and all banks. Two traditional areas, deposit fraud (check kiting, wire fraud, etc.) and loan fraud, continue to be major sources of fraud attempts and loss. The methods used to perpetrate and combat fraud continue to evolve as technology changes. Our anti-fraud actions are both preventive (anticipating lines of attack, educating employees and customers, etc.) and responsive (remediating actual attacks). Our regulators require us and all banks to report fraud promptly. Regulators often advise banks of new schemes so that the entire industry can adapt as quickly as possible. However, some level of fraud loss is unavoidable, and the risk of a major loss cannot be eliminated.
Our ability to conduct and grow our businesses is dependent in part upon our ability to create, maintain, expand, and evolve an appropriate operational and organizational infrastructure, manage expenses, and recruit and retain personnel with the ability to manage a complex business. Operational risk can arise in many ways, including: errors related to failed or inadequate physical, operational, information technology, or other processes; faulty or disabled computer or other technology systems; fraud, theft, physical security breaches, electronic data and related security breaches, or other criminal conduct by employees or third parties; and exposure to other external events. Inadequacies may present themselves in myriad ways. Actions taken to manage one risk may be ineffective against others. For example, information technology systems may be insufficiently redundant to withstand a fire, incursion, malware, or other major casualty, and they may be insufficiently adaptable to new business conditions or opportunities. Efforts to make systems more robust may make them less adaptable, and vice-versa. Also, our efforts to control expenses, which is a significant priority for us, increases our operational challenges as we strive to maintain customer service and compliance at high quality and low cost.
A serious information technology security (cybersecurity) breach can cause significant damage and at the same time be difficult to detect even after it occurs. Among other things, that damage can occur due to outright theft or extortion of our funds, fraud or identity theft perpetrated on customers, or adverse publicity associated with a breach and its potential effects. Perpetrators potentially can be employees, customers, and certain vendors, all of whom legitimately have access to some portion of our systems, as well as outsiders with no legitimate access. Because of the potentially very serious consequences associated with these risks, our electronic systems and their upgrades need to address internal and external security concerns to a high degree, and our systems have to comply with applicable banking and other regulations pertaining to bank safety and customer protection. Although many of our defenses are systemic and highly technical, others are much older and more basic. For example, periodically we train all our employees to recognize red flags associated with fraud, theft, and other electronic crimes, and we educate our customers as well through regular and episodic security-oriented communications. We expect our systems and regulatory requirements to continue to evolve as technology and criminal techniques also continue to evolve.
The operational functions we outsource to third parties may experience similar disruptions that could adversely impact us and over which we may have limited control and, in some cases, limited ability to obtain an alternate vendor quickly. To the extent we rely on third party vendors to perform or assist operational functions, the challenge of managing the associated risks may become more difficult.
The operational functions of business counterparties may experience disruptions that could adversely impact us and over which we may have limited or no control. For example, in recent years several major U.S. retailers, a major electronic mail provider, and a major credit reporting
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 24

firm all experienced data systems incursions reportedly resulting in the thefts of credit and debit card information, online account information, and other data of millions of customers. Retailer incursions affect cards issued and deposit accounts maintained by many banks, including our Bank. Although our systems are not breached in retailer incursions, these events can increase account fraud and can cause us to reissue a significant number of account cards and take other costly steps to avoid significant theft loss to our Bank and our customers. Our ability to recoup our losses may be limited legally or practically in many situations. Other possible points of incursion or disruption not within our control include internet service providers, social media portals, distant-server (“cloud”) service providers, electronic data security providers, telecommunications companies, and smart phone manufacturers.
Failure to build and maintain, or outsource, the necessary operational infrastructure, failure of that infrastructure to perform its functions, or failure of our disaster preparedness plans if primary infrastructure components suffer damage, can lead to risk of loss of service to customers, legal actions, and noncompliance with applicable regulatory standards. Additional information concerning operational risks and our management of them, all of which is incorporated into this Item 1A by this reference, appears under the caption “Operational Risk Management” beginning on page 89 of our 2019 MD&A (Item 7).
The delivery of financial services to customers and others increasingly depends upon technologies, systems, and multi-party infrastructures which are new, creating or enhancing several risks discussed elsewhere. Examples of the risks created or enhanced by the widespread and rapid adoption of relatively untested technologies include: security incursions; operational malfunctions or other disruptions; and legal claims of patent or other intellectual property infringement.
Competition for talent is substantial and increasing. Moreover, revenue growth in some business lines increasingly depends upon top talent. In recent years the cost to us of hiring and retaining top revenue-producing talent has increased, and that trend is likely to continue. The primary tools we use to attract and retain talent are: salaries; commission, incentive, and retention compensation programs; retirement benefits; change in control severance benefits; health and other welfare benefits; and our corporate culture. To the extent we are unable to use these tools effectively, we face the risk that, over time, our best talent will leave us and we will be unable to replace those persons effectively.
Incentives might operate poorly or have unintended adverse effects. Incentive programs are difficult to design well, and even if well-designed often they must be updated to address changes in our business. A poorly designed incentive program-where goals are too difficult, too easy, or not well related to desired outcomes-could provide little useful motivation to key employees, could increase turnover, and could impact customer retention. Moreover, even where those pitfalls are avoided, incentive programs may create unintended adverse consequences. For example, a program focused entirely on revenue production, without proper controls, may result in costs growing faster than revenues.

Risk from Economic Downturns and Changes

Generally, in an economic downturn, our credit losses increase, demand for our products and services declines, and the credit quality of our loan portfolio declines. Delinquencies and credit losses generally increase during economic downturns due to an increase in liquidity problems for customers and downward pressure on collateral values. Likewise, demand for loans (at a given level of creditworthiness), deposit and other products, and financial services may decline during an economic downturn, and may be adversely affected by other national, regional, or local economic factors that impact demand for loans and other financial products and
services. Such factors include, for example, changes in employment rates, interest rates, real estate prices, or expectations concerning rates or prices. Accordingly, an economic downturn or other adverse economic change (local, regional, national, or global) can hurt our financial performance in the form of higher loan losses, lower loan production levels, lower deposit levels, compression of our net interest margin, and lower fees from transactions and services. Those effects can continue for many years after the downturn technically ends.
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 25

Risks Associated with Monetary Events

The Federal Reserve has implemented significant economic strategies that have impacted interest rates, inflation, asset values, and the shape of the yield curve. These strategies have had, and will continue to have, a significant impact on our business and on many of our customers. In response to the recession in 2008 and the following uneven recovery, the Federal Reserve implemented a series of domestic monetary initiatives designed to lower rates and make credit easier to obtain. The Federal Reserve changed course in 2015, raising rates five times by 2017, in each case by a modest 25 basis points. It then raised rates four times, for a total of 100 basis points, in 2018. The last two raises were followed by substantial volatility in the U.S. stock market, and the last raise was accompanied by a substantial and broad stock market decline. In 2019 the Federal Reserve changed course again, cutting rates a total of 75 basis points. During the first two months of 2020, the Federal Reserve has signaled no clear up or down intentions for rates, indicating that future actions will depend upon changes in economic data.
Federal Reserve strategies can, and often are intended to, affect the domestic money supply, inflation, interest rates, and the shape of the yield curve. Effects on the yield curve often are most pronounced at the short end of the curve, which is of particular importance to us and other banks. Among other things, easing strategies are intended to lower interest rates, flatten the yield curve, expand the money supply, and stimulate economic activity, while tightening strategies are intended to increase interest rates, steepen the yield curve, tighten the money supply, and restrain economic activity.
Many external factors may interfere with the effects of these plans or cause them to be changed, sometimes quickly. Such factors include significant economic trends or events as well as significant international monetary
policies and events. Such strategies also can affect the U.S. and world-wide financial systems in ways that may be difficult to predict. Risks associated with interest rates and the yield curve are discussed in this Item 1A under the caption “Interest Rate and Yield Curve Risks” beginning on page 33.
We may be adversely affected by economic and political situations outside the U.S. The U.S. economy, and the businesses of many of our customers, are linked significantly to economic and market conditions outside the U.S., especially in North America, Europe, and Asia, and increasingly in Central and South America. Although we have little direct exposure to non-US-dollar-denominated assets or non-US sovereign debt, in the future major adverse events outside the U.S. could have a substantial indirect adverse impact upon us. Key potential events which could have such an impact include (i) sovereign debt default (default by one or more governments in their borrowings), (ii) bank and/or corporate debt default, (iii) market and other liquidity disruptions, and, if stresses become especially severe, (iv) the collapse of governments, alliances, or currencies, and (v) military conflicts. The methods by which such events could adversely affect us are highly varied but broadly include the following: an increase in our cost of borrowed funds or, in a worst case, the unavailability of borrowed funds through conventional markets; impacts upon our hedging and other counterparties; impacts upon our customers; impacts upon the U.S. economy, especially in the areas of employment rates, real estate values, interest rates, and inflation/deflation rates; and impacts upon us from our regulatory environment, which can change substantially and unpredictably from possible political response to major financial disruptions.

Risks Related to Businesses We May Exit

We may be unable to successfully implement a disposition or wind-down of businesses or units which no longer fit our strategic plans. We could have closures and divestitures as we continue to adapt to a changing business and regulatory environment. Key risks associated with exiting a business include:

• | our ability to price a sale transaction appropriately and otherwise negotiate acceptable terms;

• | our ability to identify and implement key customer, technology systems, and other transition actions to

avoid or minimize negative effects on retained businesses;

• | our ability to assess and manage any loss of synergies that the exited business had with our retained businesses; and

• | our ability to manage capital, liquidity, and other challenges that may arise if an exit results in significant legacy cash expenditures or financial loss.

Legacy Mortgage Business Risks

We have risks from the mortgage-related businesses we exited, including mortgage loan repurchase and loss-reimbursement risk, claims of improper foreclosure practices, claims of non-compliance with contractual and regulatory requirements, and the risk of higher default rates on loans made by our former businesses. In 2008 we exited our national mortgage and related lending businesses. However, in our non-strategic segment we still retain as assets a significant amount of loans that those businesses created. Most of those loans are secured by residential or other real estate situated across the U.S. We retain the risk of liability to customers and contractual parties with whom we dealt in the course of operating those businesses. These legacy assets and obligations continue to impose risks on us. Key risks include:

• | We are contending with, and defending litigation matters associated with, indemnity claims arising out of our former (pre-2009) mortgage origination and sale activities. The outcome of those matters is uncertain; losses in excess of current accruals (reserves) could be material. Although some types of new claims and actions no longer are legally viable due to the passage of time, others could still arise.

• | We could be subject to claims that servicing-related actions were done improperly, or improperly were not done. Although we may be able to demand indemnity in cases where servicing was performed on our behalf by another institution, there is risk that such an indemnity demand could be refused by the institution or rejected by an appropriate court.

Additional information concerning risks related to our former mortgage businesses and our management of them, all of which is incorporated into this Item 1A by this reference, is set forth: under the captions “Repurchase Obligations, Off-Balance Sheet Arrangements, and Other Contractual Obligations” beginning on page 93, “Obligations from Pre-2009 Mortgage Businesses” beginning on page 93, “Repurchase Accrual Methodology” beginning on page 93, “Foreclosure Practices” beginning on page 96, and “Contingent Liabilities” beginning on page 99 of our 2019 MD&A (Item 7); and under the captions “Material Matters” and “Exposures from pre-2009 Mortgage Business,” both beginning on page 173, within Note 17-Contingencies and Other Disclosures, of our 2019 Financial Statements (Item 8).
We have exposures related to the mortgage servicing obligations and assets which we retained after we generally sold our mortgage businesses in 2008, especially in relation to the subservicing arrangements we made between 2008 and the sale of substantially all our remaining servicing assets completed in 2014. When we sold our origination and servicing businesses in 2008 we retained significant servicing obligations and assets. Since then we engaged subservicers to provide loan servicing to borrowers and trustees on our behalf when we have been unable to divest those obligations. Complaints against the servicing provided often are directed first to us, as the servicer of record.
Additional information concerning risks related to former servicing and foreclosure practices and our management of them, all of which is incorporated into this Item 1A by this reference, is set forth under the captions “Repurchase Accrual Methodology” beginning on page 93, “Foreclosure Practices” beginning on page 96, and “Contingent Liabilities” beginning on page 99 of our 2019 MD&A (Item 7; and under the caption “Exposures from pre-2009 Mortgage Business” beginning on page 173, within Note 17-Contingencies and Other Disclosures, of our 2019 Financial Statements (Item 8).
Several large purchasers of mortgage-backed securities have filed suits against the trustees for those securitizations asserting various theories of liability. The trustee of our securitizations is defending such matters, and many of our securitizations are among those alleged to have been purchased by the plaintiffs. The claims for damages are based in part on allegations that the trustee did not properly or timely act against the originators of the securitizations or the servicers of the loans, and further assert that the trustee has affirmative duties to act which were not set forth in the legal trust documents. Some of the legal theories advanced are untested or unsettled. Although we are not a defendant in these proceedings, these complex suits may progress or evolve so as to compel us to defend ourselves or our trustee, and could create financial exposure for us.

Reputation Risks

Our ability to conduct and grow our businesses, and to obtain and retain customers, is highly dependent upon external perceptions of our business practices and
financial stability. Our reputation is, therefore, a key asset for us. Our reputation is affected principally by our business practices and how those practices are perceived and understood by others. Adverse perceptions regarding the practices of our competitors, or our industry as a whole,
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 27

also may adversely impact our reputation. In addition, negative perceptions relating to parties with whom we have important relationships may adversely impact our reputation. Senior management oversees processes for reputation risk monitoring, assessment, and management.
Damage to our reputation could hinder our ability to access the capital markets or otherwise impact our liquidity, could hamper our ability to attract new customers and retain existing ones, could impact the market value of our stock, could create or aggravate regulatory difficulties, and could undermine our ability to attract and retain talented employees, among other things. Adverse impacts on our reputation, or the reputation of our industry, also may result in greater regulatory and/or legislative scrutiny, which may lead to laws or regulations that change or constrain our business or operations. Events that result in damage to our reputation also may increase our litigation risk.
Political and social fragmentation in the U.S., combined with access to social media platforms, can increase reputation risk in ways that might not be easily avoided by traditional means. The predominant culture within the banking industry remains traditional: in order to preserve their business reputations, banks generally prefer to avoid
direct, public involvement in political or social controversy. Increasingly, though, certain groups-having highly specific political or social agendas and with the ability to communicate their views effectively using social media platforms-have made it more difficult to maintain a traditional approach. One group, for example, may publicly criticize a bank for having, as a customer, a business which “exploits” persons of limited financial means, while another group may criticize a bank for failing to have, as a customer, the same business which “serves” such persons in neighborhoods that many businesses avoid. As another example, a group may demand that a bank cease doing business with a specific business customer based on the customer’s industry or a specific business practice because that industry or practice, though legal, is objectionable to that group. While the potential for such demands has always existed, special interest groups today are more able and willing to publicize their criticisms, and some are willing to use factual exaggerations and inflammatory language in stating their views to the public. Those criticisms, in turn, ultimately may be acted upon by legislators or regulators.

Credit Risks

We face the risk that our customers may not repay their loans and that the realizable value of collateral may be insufficient to avoid a charge-off. We also face risks that other counterparties, in a wide range of situations, may fail to honor their obligations to pay us. In our business some level of credit charge-offs is unavoidable and overall levels of credit charge-offs can vary substantially over time. In the most recent credit cycle, net charge-offs were $131.8 million in 2007, and increased to $572.8 million and $832.3 million in 2008 and 2009, respectively. Beginning in 2010, net charge-offs began to decline, $12.5 million in 2017, $16.1 million in 2018, and $27.1 million in 2019. In recent years, our loan loss reserves also have declined from high levels. The allowance for loan loss was $200.3 million as of December 31, 2019, down substantially from $896.9 million and $849.2 million at year-end 2009 and 2008, respectively. We have experienced very low levels of charge-offs in recent years, and have experienced some loan-loss recoveries from loans that were charged off during the last down cycle. Net charge-offs should increase at some point when the credit cycle moves into its next phase.
Our ability to manage credit risks depends primarily upon our ability to assess the creditworthiness of loan customers and other counterparties and the value of any collateral, including real estate, among other things. We further manage credit risk by diversifying our loan portfolio, by managing its granularity, by following per-relationship lending limits, and by recording and managing an
allowance for loan losses based on the factors mentioned above and in accordance with applicable accounting rules. We further manage other counterparty credit risk in a variety of ways, some of which are discussed in other parts of this Item 1A and all of which have as a primary goal the avoidance of having too much risk concentrated with any single counterparty.
We record loan charge-offs in accordance with accounting and regulatory guidelines and rules. As indicated in this Item 1A under the caption “Accounting & Tax Risks” beginning on page 35, these guidelines and rules could change and cause provision expense or charge-offs to be more volatile, or to be recognized on an accelerated basis, for reasons not always related to the underlying performance of our portfolio. (In fact, as mentioned there, starting January 1, 2020, such an accounting change is applicable to us.) Moreover, the SEC or PCAOB could take accounting positions applicable to our holding company that may be inconsistent with those taken by the Federal Reserve, OCC, or other banking regulators.
A significant challenge for us is to keep the credit and other models and approaches we use to originate and manage loans updated to take into account changes in the competitive environment, in real estate prices and other collateral values, in the economy, and in the regulatory environment, among other things, based on our experience originating loans and servicing loan portfolios. Changes in modeling could have significant impacts upon our reported
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 28

financial results and condition. In addition, we use those models and approaches to manage our loan portfolios and lending businesses. To the extent our models and approaches are not consistent with underlying real-world conditions, our management decisions could be misguided or otherwise affected with substantial adverse consequences to us.
The recent low-interest rate environment has elevated the traditional challenge for lenders and investors to balance taking on higher risk against the desire for higher income or yield. This challenge applies not only to credit risk in lending activities but also to default and rate risks regarding investments.
If interest rates rise, default risk also rises. As borrowers’ obligations to pay interest increase, financial weaknesses become more evident. Initially this results in lower consumer credit scores and lower commercial loan grading, and later results in higher default rates.
Credit losses tend to increase and decrease in a cyclical manner. Although the duration and timing of any given credit cycle is impossible to predict accurately, it is clear that we and other U.S. banks recently have experienced an extended period of very low credit losses, and that period followed several years of extremely high losses. It is inevitable that credit losses will rise well beyond current levels when the next cycle begins. It is extremely difficult for banks, and for investors, to know when an uptick in credit loss is merely idiosyncratic or instead portends a major credit cycle change.
The composition of our loan portfolio inherently increases our sensitivity to certain credit risks. At December 31, 2019, approximately 65% of total loans consisted of the commercial, financial, and industrial (C&I) category, while approximately 19% consisted of the consumer real estate category.
The largest component of the C&I category at year end was loans to mortgage companies, a component which represented about 22% of the C&I category at that time. The second largest component was loans to finance and insurance companies. As a result, approximately 36% of the C&I category was sensitive to impacts on the financial services industry. As discussed elsewhere in this Item 1A with respect to our company, the financial services industry is more sensitive to interest rate and yield curve changes, monetary policy, regulatory policy, changes in real estate and other asset values, and changes in general economic conditions, than many other industries. Negative impacts on the industry could dampen new lending in these lines of business and could create credit impacts for the loans in our portfolio.
The consumer real estate category contains a number of concentrations which affect credit risk assessment of the category.

• | Product concentration. The consumer real estate category consists primarily of consumer installment loans, and much of the remainder consists of home equity lines of credit.

• | Collateral concentration. This entire category is secured by residential real estate. Approximately 20% of the category consists of loans secured on a second-lien basis.

• | Geographic concentration. At year end about 54% of the category related to Tennessee customers, 15% related to North Carolina, 13% related to Florida, 3% related to California, and no other state represented more than 3% of the category.

• | Legacy concentration. We still have approximately $.8 billion of loans originated before 2009 by our legacy national mortgage lending business. Those include loans we originated and did not sell, along with loans we have repurchased in the course of resolving claims with loan buyers. Our legacy loan portfolio continues to shrink, but the rate of shrinkage is slowing.

The consumer real estate category is highly sensitive to economic impacts on consumer customers and on residential real estate values. Job loss or downward job migration, as well as significant life events such as divorce, death, or disability, can significantly impact credit evaluations of the portfolio. Also, regulatory changes, discussed above and elsewhere in this Item 1A, are more likely to affect the consumer category and our accounting estimates of credit loss than other loan types.
Volatility in the oil & gas industry can impact us. Our Houston office specializes in commercial lending. That office significantly focuses on three areas: energy, commercial real estate (CRE), and commercial, financial, & industrial (C&I). Much of our Houston business is connected, at least in part, to the energy industry, especially oil and gas production and distribution. In addition to general credit and other risks mentioned elsewhere in this Item 1A, the energy business and related assets are sensitive to a number of factors specific to that industry. Key among those is global demand for energy and other products from oil and gas in relation to supply. The shifting balance between demand and supply is expressed most simply in prices. Significant oil-price volatility can and often does impact our overall business in this industry by increasing charge-offs and reducing demand for loans.
Additional information concerning credit risks and our management of them is set forth under the captions “Asset Quality-Trend Analysis of 2019 Compared to 2018” beginning on page 65, “Commercial Loan Portfolios” beginning on page 65, “Consumer Loan Portfolios” beginning on page 71, “Credit Risk Management” beginning on page 90, and “Allowance for Loan Losses” beginning on page 97 of our 2019 MD&A (Item 7).
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 29

Service Risks

We provide a wide range of services to customers, and the provision of these services may create claims against us that we provided them in a manner that harmed the customer or a third party, or was not compliant with applicable laws or rules. Our services include lending, loan servicing, fiduciary, custodial, depositary, funds management, insurance, and advisory services, among others. We manage these risks primarily through training programs, compliance programs, and supervision
processes. Additional information concerning these risks and our management of them, all of which is incorporated into this Item 1A by this reference, appears under the captions “Operational Risk Management” and “Compliance Risk Management,” beginning on pages 89 and 90, respectively, of our 2019 MD&A (Item 7).

Regulatory, Legislative, and Legal Risks

The regulatory environment continues to be challenging. We operate in a heavily regulated industry. Our regulatory burdens, including both operating restrictions and ongoing compliance costs, are substantial.
We are subject to many banking, deposit, insurance, securities brokerage and underwriting, and consumer lending regulations in addition to the rules applicable to all companies publicly traded in the U.S. securities markets and, in particular, on the New York Stock Exchange. Failure to comply with applicable regulations could result in financial, structural, and operational penalties. In addition, efforts to comply with applicable regulations may increase our costs and/or limit our ability to pursue certain business opportunities. See “Supervision and Regulation” in Item 1 of this report, beginning on page 8, for additional information concerning financial industry regulations. Federal and state regulations significantly limit the types of activities in which we, as a financial institution, may engage. In addition, we are subject to a wide array of other regulations that govern other aspects of how we conduct our business, such as in the areas of employment and intellectual property. Federal and state legislative and regulatory authorities increasingly consider changing these regulations or adopting new ones. Such actions could further limit the amount of interest or fees we can charge, could further restrict our ability to collect loans or realize on collateral, could affect the terms or profitability of the products and services we offer, or could materially affect us in other ways.
The following paragraphs highlight certain specific important risk areas related to regulatory matters currently. These paragraphs do not describe these risks exhaustively, and they do not describe all such risks that we face currently. Moreover, the importance of specific risks will grow or diminish as circumstances change.
We and our Bank both are required to maintain certain regulatory capital levels and ratios. U.S. capital standards are discussed in Item 1 of this report, in tabular and narrative form, under the caption “Capital Adequacy” starting on page 11. Pressures to maintain appropriate
capital levels and address business needs in a changing economy may lead to actions that could be dilutive or otherwise adverse to our shareholders. Such actions could include: reduction or elimination of dividends; the issuance of common or preferred stock, or securities convertible into stock; or the issuance of any class of stock having rights that are adverse to those of the holders of our existing classes of common or preferred stock.
Additional information concerning these risks and our management of them, all of which is incorporated into this Item 1A by this reference, appears: under the captions “Capital Adequacy” and “Prompt Corrective Action (PCA)” in Item 1 of this report beginning on pages 11 and 12, respectively; under the captions “Capital-2019 Compared to 2018,” “Capital Risk Management and Adequacy,” and “Market Uncertainties and Prospective Trends” beginning on pages 63, 89, and 96, respectively, of our 2019 MD&A (Item); and under the caption “Regulatory Capital” in Note 12-Regulatory Capital and Restrictions, beginning on page 164 of our 2019 Financial Statements (Item 8).
Legal disputes are an unavoidable part of business, and the outcome of pending or threatened litigation cannot be predicted with any certainty. We face the risk of litigation from customers, employees, vendors, contractual parties, and other persons, either singly or in class actions, and from federal or state regulators. We manage those risks through internal controls, personnel training, insurance, litigation management, our compliance and ethics processes, and other means. However, the commencement, outcome, and magnitude of litigation cannot be predicted or controlled with any certainty.
Typically, we are unable to estimate our loss exposure from legal claims until relatively late in the litigation process, which can make our financial recognition of loss from litigation unpredictable and highly uneven from one period to the next. For most of our pending legal matters we have established either no accrual (reserve) or no significant reserve. Financial accounting guidance requires that litigation loss be both estimable and
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 30

probable before a reserve may be established (recorded as a liability on our balance sheet). Under that guidance, reserves typically are not established for most litigation matters until after preliminary motions to dismiss or to narrow the case are resolved, after discovery is substantially in process, and (in many cases) after preliminary overtures regarding settlement have occurred. Potentially significant cases often are pending for years before any loss is recognized and a reserve is established. Moreover, many cases experience relatively little progress toward resolution for a long period followed by a brief period of rapid development. Lastly, although most cases are resolved with little or no loss to us, for the others our loss typically is recognized either all at once (near the time of resolution) or very unevenly over the life of the case.
Additional information concerning litigation risks and our management of them, all of which is incorporated into this Item 1A by this reference, appears: under the caption “Legacy Mortgage Business Risks” beginning on page 26 of this report; under the captions “Repurchase Obligations, Off-Balance Sheet Arrangements, and Other Contractual Obligations,” “Repurchase Accrual Methodology,” “Market Uncertainties and Prospective Trends,” and “Contingent Liabilities” beginning on pages 93, 93, 96, and 99, respectively, of our 2019 MD&A (Item 7); and under the caption “Contingencies” in Note 17-Contingencies and Other Disclosures, beginning on page 172 of our 2019 Financial Statements (Item 8).
Political dysfunction and volatility within the federal government, both at the regulatory and Congressional level, creates significant potential for major and abrupt shifts in federal policy regarding bank regulation, taxes, and the economy, any of which could have significant impacts on our business and financial performance. Moreover, political conflict within and among branches of government, and within and among government agencies, can rise to a level where day-to-day functions could be interrupted or impaired.
Data privacy is becoming a major political concern. The laws governing it are new, and are likely to evolve and expand. Many non-regulated, non-banking companies have gathered large amounts of personal details about millions of people, and have the ability to analyze that data and act on that analysis very quickly. This situation has prompted governmental responses. Two prominent responses are the European Union General Data Protection Regulation and the California Data Privacy Protection Act. Neither is a banking industry regulation, but both apply to banks in relation to certain customers. Further general regulation to protect data privacy appears likely, and banking industry regulations might be enlarged as well.
Public expectations concerning corporate controls on emissions of carbon dioxide, methane, and other greenhouse gases could increase our operating costs in the future without a corresponding increase in revenue, could curtail some aspects of our business, or both. At present, environmental regulations do not require us to monitor the direct or indirect greenhouse gas emissions associated with building, operating, or maintaining our physical facilities, nor are we taxed or fined in relation to those emissions, because such gases generally are not considered to be pollutants under federal law. Changing expectations could pressure us to physically measure, monitor, and curtail direct emissions and to estimate indirect emissions or impacts, and eventually could result in legal requirements to take those actions or to pay for measured or estimated emissions. Whether or not legally required, any such actions that we take would increase our operating costs. In addition, such expectations could pressure us to discontinue business relationships with certain customers, or groups of customers, that have suboptimal reputations for emissions.

Risks of Expense Control

Our ability to successfully manage expenses is important to our long-term survival and prosperity but in part is subject to risks beyond our control. Many factors can influence the amount of our expenses, as well as how quickly they grow. As our businesses change-whether by acquisition, expansion, or contraction-additional expenses can arise from asset purchases, structural reorganization, evolving business strategies, and changing regulations, among other things.
We manage controllable expenses and risk through a variety of means, including selectively outsourcing or multi-sourcing various functions and procurement coordination and processes. In recent years we have actively sought to make strategic businesses more efficient
primarily by investing in technology, re-thinking and right-sizing our physical facilities, and re-thinking and right-sizing our workforce and incentive programs. These efforts usually entail additional near-term expenses in the form of technology purchases and implementation, facility closure or renovation costs, and severance costs, while expected benefits typically are realized with some uncertainty in the future.
We have also focused our attention on the economic profit generated by our business activities and prospects rather than emphasizing revenues or ordinary profit. Economic profit analysis attempts to relate ordinary profit to the capital employed to create that profit with the goal of achieving higher (more efficient) returns on capital
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 31

employed overall. Activities with higher capital usage bear a greater burden in economic profit analysis. The process is intended to allow us to more efficiently manage investment and utilization of resources. Economic profit analysis involves significant judgment regarding capital allocation. Mistakes in those judgments could result in a misallocation of resources and diminished profitability over the long run.
Despite our efforts, our costs could rise due to adverse structural changes or market shifts. For example, the overall cost of our health insurance benefit is highly dependent upon regulatory factors and market forces beyond our control.

Geographic Risks

We are subject to risks of operating in various jurisdictions. To a significant degree our banking business is exposed to economic, regulatory, natural disaster, and other risks that primarily impact Tennessee and neighboring states where we do our traditional banking business. If the southeastern U.S. were to experience adversity not shared by other parts of the country, we are likely to experience adversity to a degree not shared by those competitors which have a broader or different regional footprint. Examples of these kinds of risks include: earthquakes in Memphis; hurricanes in Florida, the Carolina coasts, or the Texas coast; a major change in health insurance laws impacting the many healthcare companies in middle Tennessee; and automotive industry plant closures.
We have international assets in the form of loans and letters of credit. Holding non-U.S. assets creates a number
of risks: the risk that taxes, fees, prohibitions, and other barriers and constraints may be created or increased by the U.S. or other countries that would impact our holdings; the risk that currency exchange rates could move unfavorably so as to diminish the U.S. dollar value of assets, or to enlarge the U.S. dollar value of liabilities; and the risk that legal recourse against foreign counterparties may be limited in unexpected ways. Our ability to manage those and other risks depends upon a number of factors, including: our ability to recognize and anticipate differences in legal, cultural, and other expectations applicable to customers, regulators, vendors, and other business partners and counterparties; and our ability to recognize and manage any exchange rate risks to which we are exposed.

Insurance

Our property and casualty insurance may not cover or may be inadequate to cover the risks that we face, and we are or may be adversely affected by a default by insurers. We use insurance to manage a number of risks, including damage or destruction of property as well as legal and other liability. Not all such risks are insured, in any given insured situation our insurance may be inadequate to cover all loss, and many risks we face are uninsurable. For those risks that are insured, we also face the risks that the insurer may default on its obligations or that the insurer may refuse to honor them. We treat the risk of default as a type of credit risk, which we manage by reviewing the insurers that we use and by striving to use more than one insurer when practical. The risk of refusal, whether due to honest disagreement or bad faith, is inherent in any contractual situation.
A portion of our consumer loan portfolio involves mortgage default insurance. If a default insurer were to experience a significant credit downgrade or were to become insolvent, that could adversely affect the carrying value of loans insured by that company, which could result in an immediate increase in our loan loss provision or write-down of the carrying value of those loans on our balance sheet and, in either case, a corresponding impact
on our financial results. If many default insurers were to experience downgrades or insolvency at the same time, the risk of a financial impact would be amplified.
We own certain bank-owned life insurance policies as assets on our books. Some of those policies are “general account” and others are “separate account.” The general account policies are subject to the risk that the carrier might experience a significant downgrade or become insolvent. The separate account policies are less susceptible to carrier risk, but do carry a higher risk of value fluctuations in securities which underlie those policies. Both risks are managed through periodic reviews of the carriers and the underlying security values. However, particularly for the general account policies, our ability to liquidate a policy in anticipation of an adverse carrier event is significantly limited by applicable insurance contracts and regulations as well as by a substantial tax penalty which could be levied upon early policy termination.
When we self-insure certain exposures, our estimates of future expenditures may be inadequate for the actual expenditures that occur. For example, we self-insure our employee health-insurance benefit program. We estimate future expenditures and establish accruals (reserves) based
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 32

on the estimates. If actual expenditures were to exceed our estimates in a future period, our future expenses could be adversely and unexpectedly increased.

Liquidity and Funding Risks

Liquidity is essential to our business model and a lack of liquidity, or an increase in the cost of liquidity, may materially and adversely affect our businesses, results of operations, financial conditions and cash flows. In general, the costs of our funding directly impact our costs of doing business and, therefore, can positively or negatively affect our financial results. Our funding requirements in 2019 were met principally by deposits, by financing from other financial institutions, and by funds obtained from the capital markets.
Deposits traditionally have provided our most affordable funds and by far the largest portion of funding. However, deposit trends can shift with economic conditions. If interest rates rise, deposit levels in our Bank might fall, perhaps fairly quickly if a tipping point is reached, as depositors become more comfortable with risk and seek higher returns in other vehicles. This could pressure us to raise our deposit rates, which could shrink our net interest margin if loan rates do not rise correspondingly.
The market among banks for deposits may be impacted by current capital rules. Those rules generally provide favorable treatment for core deposits. Institutions with less than $100 billion of assets are not required to maintain a minimum Liquidity Coverage ratio. At or above $100 billion, the requirement increases with size and certain activities. The largest banks, which must maintain the highest minimum ratio, may be incented to compete for core deposits vigorously. Although mid-sized banks, like ours, are only lightly impacted by this rule, if some large banks in our markets take aggressive actions we could lose deposit share or be compelled to adjust our deposit pricing and practices in ways that could increase our costs.
We also depend upon financing from private institutional or other investors by means of the capital markets. In 2015 we issued $500 million of senior holding-company notes due 2020. The 2015 notes refinanced an earlier five-year notes issue. Presently we believe we could access the capital markets again if we desired to do so. Risk remains, however, that capital markets may become unavailable to us for reasons beyond our control.
A number of more general factors could make funding more difficult, more expensive, or unavailable on affordable terms, including, but not limited to, our financial results, organizational or political changes, adverse impacts on our reputation, changes in the activities of our business partners, disruptions in the capital markets, specific events that adversely impact the financial services industry, counterparty availability, changes affecting our loan portfolio or other assets, changes affecting our corporate and regulatory structure, interest rate fluctuations, ratings agency actions, general economic conditions, and the legal, regulatory, accounting, and tax environments governing our funding transactions. In addition, our ability to raise funds is strongly affected by the general state of the U.S. and world economies and financial markets as well as the policies and capabilities of the U.S. government and its agencies, and may remain or become increasingly difficult due to economic and other factors beyond our control.
Events affecting interest rates, markets, and other factors may adversely affect the demand for our products and services in our fixed income business. As a result, disruptions in those areas may adversely impact our earnings in that business unit.

Credit Ratings

Our credit ratings directly affect the availability and cost of our unsecured funding. FHN and the Bank currently receive ratings from several rating agencies for unsecured borrowings. A rating below investment grade typically reduces availability and increases the cost of market-based funding. A debt rating of Baa3 or higher by Moody’s Investors Service, or BBB- or higher by Fitch Ratings, is considered investment grade for many purposes. At December 31, 2019, both rating agencies rated the unsecured senior debt of FHN and of the Bank as investment grade. The ratings outlook was stable from
Moody’s and from Fitch for both FHN and the Bank. To the extent that in the future we depend on institutional borrowing and the capital markets for funding and capital, we could experience reduced liquidity and increased cost of unsecured funding if our debt ratings were lowered further, particularly if lowered below investment grade. In addition, other actions by ratings agencies can create uncertainty about our ratings in the future and thus can adversely affect the cost and availability of funding, including placing us on negative outlook or on watchlist. Please note that a credit rating is not a recommendation to
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 33

buy, sell, or hold securities, is subject to revision or withdrawal at any time, and should be evaluated independently of any other rating.
Reductions in our credit ratings could result in counterparties reducing or terminating their relationships with us. Some parties with whom we do business may have internal policies restricting the business that can be done with financial institutions, such as the Bank, that have credit ratings lower than a certain threshold.
Reductions in our credit ratings could allow some counterparties to terminate and immediately force us to
settle certain derivatives agreements, and could force us to provide additional collateral with respect to certain derivatives agreements. Under our margin agreements, we are required to post collateral in the amount of our derivative liability positions with most derivative counterparties. At this time, those of our ISDA master agreements which have ratings triggers reference the lower of Standard & Poor’s Financial Services LLC or Moody’s ratings. If a credit rating downgrade had occurred as of December 31, 2019, the maximum specified additional collateral we would have been required to post would have been approximately $1 million.

Interest Rate and Yield Curve Risks

We are subject to interest rate risk because a significant portion of our business involves borrowing and lending money, and investing in financial instruments. A significant portion of our funding comes from short-term and demand deposits, while a significant portion of our lending and investing is in medium-term and long-term instruments. Changes in interest rates directly impact our revenues and expenses, and could expand or compress our net interest margin. We actively manage our balance sheet to control the risks of a reduction in net interest margin brought about by ordinary fluctuations in rates. In addition, our fixed income segment tends to perform better when rates decline or markets are volatile, which tends to partially offset net interest margin compression.
A flat or inverted yield curve may reduce our net interest margin and adversely affect our lending and fixed income businesses. The yield curve simply shows the interest rates applicable to short and long term debt. The curve is steep when short-term rates are much lower than long-term rates; it is flat when short-term rates are nearly equal to long-term rates; and it is inverted when short-term rates exceed long-term rates. Historically, the yield curve usually is upwardly sloped (higher rates for longer terms). However, the yield curve can be relatively flat or inverted (sloped downward), which happened several times in 2018 and 2019. A flat or inverted yield curve tends to decrease net interest margin, which would adversely impact our lending businesses, and it tends to reduce demand for long-term debt securities, which would adversely impact the revenues of our fixed income business.
We appear to be in a waiting period in terms of interest rate policy; the uncertainties of the direction, magnitude, and timing of future rate actions could adversely affect us. The Federal Reserve raised short-term rates by 0.25% four times in 2018 and reduced rates by 0.25% three times in 2019. The 2018 actions flattened the yield curve. The 2019 actions steepened the curve only very modestly. The Federal Reserve has signaled no direction for rate changes in 2020 or 2021. If rates in fact
remain stable and market participants come to expect long-term stability, the yield curve may steepen to a more normal shape, which should benefit us. However, in the meantime, in many respects the impact on us of uncertain interest rate policy is likely to be uneven, with benefits and detriments that are difficult to predict. See “Risks Associated with Monetary Events” beginning on page 25 of this report for additional information.
Market-indexed deposit products are very sensitive to changes in short-term rates, and our use of them increases our exposure to such changes.
Expectations by the market regarding the direction of future interest rate movements can impact the demand for fixed income investments which in turn can impact the revenues of our fixed income business. That risk is most apparent during times when strong expectations have not yet been reflected in market rates, or when expectations are especially weak or uncertain.
The likely discontinuance of LIBOR as a viable benchmark rate after 2021 may adversely affect our business and our operating results. In 2017, the Chief Executive of the United Kingdom Financial Conduct Authority, which regulates the London InterBank Offered Rate (LIBOR), announced that it intends to halt persuading or compelling banks to submit rates for the calculation of LIBOR after 2021. As a result, LIBOR as currently operated may not continue after 2021. It is impossible to predict whether and to what extent banks will continue to provide LIBOR submissions to the administrator of LIBOR or whether any additional reforms to LIBOR may be enacted in the United Kingdom or elsewhere. There are serious doubts that LIBOR will continue after 2021 in a form that will be practical.
At this time, it is not clear which rate or rates may become accepted alternatives to LIBOR. The leading alternative rate in the U.S., the Secured Overnight Financing Rate (SOFR) published by the Federal Reserve Bank of New York, is not directly comparable to LIBOR and cannot easily or simply be substituted for it in outstanding instruments. Key differences between the two are: SOFR is
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 34

based on secured lending, LIBOR is not; and SOFR historically has been published only as an overnight rate, while LIBOR is published in several short-term maturity periods. (Starting in March 2020, a compounded average SOFR will be published for periods of 30, 90, and 120 days, which is intended to address the latter difference.) It is impossible to predict the effect of SOFR or any other alternatives on the value of LIBOR-based securities and variable rate loans.
Our primary exposures to LIBOR are in variable-rate loans and in hedging transactions. We are not able to determine the impact on us that LIBOR discontinuance will have. The simplicity and long history of using LIBOR, the lack of a definite alternative, and the possibility that different alternatives ultimately may be used in different circumstances, means that LIBOR continues to be used in many new instruments.
In addition, it is not known how a transition away from LIBOR, or to a new version of LIBOR, will impact our ability to use hedge accounting after 2021. However, accounting and tax agencies have issued preliminary guidance that should ease that transition.
A few instruments issued by us, including the Bank’s Class A Non-Cumulative Perpetual Preferred Stock and
certain trust preferred obligations, have floating rate terms based on LIBOR. As mentioned above, it is not known whether LIBOR will continue after 2021 in a workable form. We have risk that an adverse outcome of the LIBOR transition after 2021 could increase our interest, dividend, and other costs relative to those instruments. We may not be able to refinance those instruments on terms that reduce those costs to the level we would have expected if LIBOR were to continue indefinitely, unchanged. Additionally, a transition from LIBOR could adversely impact or change our hedge accounting practices.

Asset Inventories and Market Risks

The trading securities inventories and loans held for sale in our fixed income business are subject to market and credit risks. In the course of that business we hold trading securities inventory and loan positions for purposes of distribution to customers, and we are exposed to certain market risks attributable principally to credit risk and interest rate risk associated with those assets. We manage the risks of holding inventories of securities and loans through certain market risk management policies and procedures, including, for example, hedging activities and Value-at-Risk (“VaR”) limits, trading policies, modeling, and stress analyses. Average fixed income trading securities (long positions) were $1.4 billion for 2019, $1.6 billion for 2018, and $1.2 billion for 2017. Average fixed income trading liabilities (short positions) were $0.5 billion, $0.7 billion, and $0.7 billion for 2019, 2018, and 2017, respectively. Average loans held for sale in our fixed income business were $0.5 billion, $0.6 billion, and $0.3 billion for 2019, 2018, and 2017. Additional information concerning these risks and our management of them, all of which is incorporated into this Item 1A by this reference, appears under the caption “Market Risk Management” beginning on page 87 of our 2019 MD&A (Item 7).
Declines, disruptions, or precipitous changes in markets or market prices can adversely affect our fees and other income sources. We earn fees and other income related to our brokerage business and our management of assets for
customers. Declines, disruptions, or precipitous changes in markets or market prices can adversely affect those revenue sources.
Significant changes to the securities market’s performance can have a material impact upon our assets, liabilities, and financial results. We have a number of assets and obligations that are linked, directly or indirectly, to major securities markets. Significant changes in market performance can have a material impact upon our assets, liabilities, and financial results.
An example of that linkage is our obligation to fund our pension plan so that it may satisfy benefit claims in the future. Our pension funding obligations generally depend upon actuarial estimates of benefits claims, the discount rate used to estimate the present values of those claims, and estimates of plan asset values. Our obligations to fund the plan can be affected by changes in any of those three factors. Accordingly, our obligations diminish if the plan’s investments perform better than expectations or if estimates are changed anticipating better performance, and can grow if those investments perform poorly or if expectations worsen. A rise in interest rates is likely to negatively impact the values of fixed income assets held in the plan, but would also result in an increase in the discount rate used to measure the present value of future benefit payments. Similarly, our obligations can be impacted by changes in mortality tables or other actuarial inputs. We manage the risk of rate changes by investing
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 35

plan assets in fixed income securities having maturities aligned with the expected timing of payouts. Because there are no new participants, the actuarial-input risk should slowly diminish over time.
Changes in our funding obligation generally translate into positive or negative changes in our pension expense over time, which in turn affects our financial performance. Our obligations and expenses relative to the plan can be affected by many other things, including changes in our participating employee population and changes to the plan itself. Although we have taken actions intended to moderate future volatility in this area, risk of some level of volatility is unavoidable.
Our hedging activities may be ineffective, may not adequately hedge our risks, and are subject to credit risk. In the normal course of our businesses we attempt to create partial or full economic hedges of various, though
not all, financial risks. For example: our fixed income unit manages interest rate risk on a portion of its trading portfolio with short positions, futures, and options contracts; and, we use derivatives, including swaps, swaptions, caps, forward contracts, options, and collars, that are designed to moderate the impact on earnings as interest rates change. Generally, in the latter example these hedged items include certain term borrowings and certain held-to-maturity loans.
Hedging creates certain risks for us, including the risk that the other party to the hedge transaction will fail to perform (counterparty risk, which is a type of credit risk), and the risk that the hedge will not fully protect us from loss as intended (hedge failure risk). Unexpected counterparty failure or hedge failure could have a significant adverse effect on our liquidity and earnings.

Accounting & Tax Risks

The preparation of our consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make significant estimates that affect the financial statements. The estimate that is consistently one of our most critical is the level of the allowance for credit losses. However, other estimates can be highly significant at discrete times or during periods of varying length, for example the valuation (or impairment) of our deferred tax assets. Estimates are made at specific points in time. As actual events unfold, estimates are adjusted accordingly. Due to the inherent nature of these estimates, it is possible that, at some time in the future, we may significantly increase the allowance for credit losses and/or sustain credit losses that are significantly higher than the provided allowance, or we may recognize a significant provision for impairment of assets, or we may make some other adjustment that will differ materially from the estimates that we make today. Moreover, in some cases, especially concerning litigation and other contingency matters where critical information is inadequate, often we are unable to make estimates until fairly late in a lengthy process.
We lack first-hand visibility regarding certain loans, other assets, or liabilities which increases the risk that our estimates may be inaccurate. For example, interagency supervisory guidance related to practices for loans and lines of credit secured by junior liens on 1-4 family residential properties requires that the performance of the first lien should be considered when assessing the collectability and inherent loss of a performing junior lien. We own and service a consumer real estate portfolio that is primarily composed of home equity lines and installment loans. As of December 31, 2019, that amount was $6.0 billion. As of December 31, 2019, approximately $.9 billion, or 15%, of the consumer real estate portfolio
consisted of stand-alone second liens while $.1 billion, or 2%, were second liens whose first liens are owned or serviced by FHN. We are not able to actively monitor the performance status of the first liens that are serviced by others. 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. It is possible that if our evaluation methods change or information sources otherwise improve our additions to nonperforming loans may be material.
Changes in accounting rules can significantly affect how we record and report assets, liabilities, revenues, expenses, and earnings. Although such changes generally affect all companies in a given industry, in practice changes sometimes have a disparate impact due to differences in the circumstances or business operations of companies within the same industry.
One such accounting change, ASU 2016-13, “Measurement of Credit Losses on Financial Instruments,” substantially revises the measurement and recognition of credit losses for certain assets, including most loans, in a manner that will substantially and adversely change when and how we recognize loan loss. ASU 2016-13 is effective for us on January 1, 2020. Under ASU 2016-13, when we make or acquire a new loan that is covered by the standard, we will be required to recognize immediately the “current expected credit loss,” or “CECL,” of that loan. We will also re-evaluate CECL each quarter that the loan is outstanding. CECL is the difference between our cost and the net amount we expect to collect over the life of the loan using certain estimation methods and our experience with other, similar loans. In contrast, the current accounting standard
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 36

delays recognition of credit loss until loss is “probable” (very likely). We adopted ASU 2016-13 and CECL accounting starting in 2020, with the impact on regulatory capital having a short phase-in period. Starting in 2020, recognition of estimated credit loss will be significantly accelerated compared to pre-CECL practice. Additional information concerning ASU 2016-13 and its effects upon us appears in Note 1-Summary of Significant Accounting Policies within our 2019 Financial Statements (Item 8), under the heading “Accounting Changes Issued but Not Currently Effective” beginning on page 132, which information is incorporated into this Item 1A by reference.
In comparison with former (pre-2020) standards, CECL accounting likely will: result in a significant increase in our loan loss provision (expense) and allowance (reserve) during any period of loan growth, including organic growth and growth created by acquisition or merger; through the increased provision, adversely impact our earnings and, correspondingly, our regulatory capital levels; and enhance volatility in loan loss provision and allowance levels from quarter to quarter and year to year, especially during times when the economy is in transition. Moreover, CECL creates an incentive for banks to reduce new lending in the “down” part of the economic cycle in order to reduce loss
recognition and conserve regulatory capital. That perverse incentive could, nationwide, prolong a down cycle in the economy and delay a recovery.
Changes in regulatory rules can create significant accounting impacts for us. Because we operate in a regulated industry we prepare regulatory financial reports based on regulatory accounting standards. Changes in those standards can have significant impacts upon us in terms of regulatory compliance. In addition, such changes can impact our ordinary financial reporting, and uncertainties related to regulatory changes can create uncertainties in our financial reporting.
Our Controls and Procedures May Fail or Be Circumvented. Internal controls, disclosure controls and procedures, and corporate governance policies and procedures (“controls and procedures”) must be effective in order to provide assurance that financial reports are materially accurate. A failure or circumvention of our controls and procedures or failure to comply with regulations related to controls and procedures could have a material adverse effect on our business, financial condition and results of operations.

Stock-Holding and Governance Risks

The principal source of cash flow to pay dividends on our stock, as well as service our debt, is dividends and distributions from the Bank, and the Bank may become unable to pay dividends to us without regulatory approval. We primarily depend upon common dividends from the Bank for cash to fund dividends we pay to our common and preferred stockholders, and to service our outstanding debt. Regulatory constraints might prevent the Bank from declaring and paying dividends to us in 2020 without regulatory approval. Applying the applicable regulatory rules, at January 1, 2020, the Bank could legally declare cash dividends on the Bank's common or preferred stock of approximately $331.2 million without obtaining regulatory approval.
Also, we are required to provide financial support to the Bank. Accordingly, at any given time a portion of our funds may have to be used for that purpose and therefore would be unavailable for dividends.
Furthermore, the Federal Reserve has issued policy statements generally requiring insured banks and bank holding companies only to pay dividends out of current operating earnings. The Federal Reserve has released a supervisory letter advising bank holding companies, among other things, that as a general matter a bank holding company should inform the Federal Reserve and should eliminate, defer or significantly reduce its dividends if (i) the bank holding company’s net income available to
shareholders for the past four quarters, net of dividends previously paid during that period, is not sufficient to fully fund the dividends; (ii) the bank holding company’s prospective rate of earnings is not consistent with the bank holding company’s capital needs and overall current and prospective financial condition; or (iii) the bank holding company will not meet, or is in danger of not meeting, its minimum regulatory capital adequacy ratios.
Our stockholders may suffer dilution if we raise capital through public or private equity financings to fund our operations, to increase our capital, or to expand. If we raise funds by issuing equity securities or instruments that are convertible into equity securities, the percentage ownership of our current common stockholders will be reduced, the new equity securities may have rights and preferences superior to those of our common or outstanding preferred stock, and additional issuances could be at a sales price which is dilutive to current stockholders. We may also issue equity securities directly as consideration for acquisitions we may make that would be dilutive to stockholders in terms of voting power and share-of-ownership, and could be dilutive financially or economically.
The IBKC merger, for example, will result in a significant increase in our outstanding shares. We estimate that immediately after the IBKC merger, FHN will issue to former IBKC shareholders FHN common
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 37

shares representing about 44% of our post-closing outstanding shares; legacy FHN shareholders will own only about 56% of the post-closing outstanding shares. We hope to mitigate the financial and economic (per-share) dilutive effects of that issuance by integrating IBKC’s businesses and operations with our current businesses and operations effectively and at an acceptable level of cost, and as a result achieving net expense reductions and net revenue increases in comparison with the two companies on a stand-alone basis. A key risk is that we will fail to achieve one or more of those results.
Our issuance of preferred stock raises regulatory capital without issuing common shares, but creates or expands our general obligation to pay all preferred dividends ahead of any common dividends. Currently we have two series of preferred stock outstanding, one issued by the Bank and one by FHN. After the IBKC merger closes, FHN will have outstanding three additional series of preferred stock. Subject to capital needs and market conditions, additional series may be issued in the future.
Provisions of Tennessee law, and certain provisions of our charter and bylaws, could make it more difficult for a third party to acquire control of us or could have the effect of discouraging a third party from attempting to acquire control of us. These provisions could make it more difficult for a third party to acquire us even if an acquisition might be at a price attractive to many of our stockholders. In addition, federal banking laws prohibit non-financial-industry companies from owning a bank, and require regulatory approval of any change in control of a bank.
Certain legal rights of holders of our stock to pursue claims against us are limited by our bylaws. Our bylaws have an exclusive forum clause which provides, unless we
consent in writing to an alternative forum, that a state or federal court located within Shelby County in the State of Tennessee will be the sole and exclusive forum for (i) any derivative action or proceeding brought in the right of FHN, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of FHN to FHN or its shareholders, (iii) any action asserting a claim against FHN or any director, officer or other employee of FHN arising pursuant to any provision of the Tennessee Business Corporation Act, of FHN’s charter, or of its bylaws, or (iv) any action asserting a claim against FHN or any director, officer or other employee of FHN that is governed by the internal affairs doctrine.
The bylaws’ exclusive forum clause may have the effect of discouraging lawsuits against FHN or its directors, officers or other employees, or against the depositary, as applicable. The clause also may lead to increased costs to bring a claim, or may limit the ability of holders of FHN’s stock to bring a claim in a judicial forum they find favorable.
In addition, to the fullest extent permitted by law, the exclusive forum clause will apply to any actions or proceedings described in the four categories specified above that arise or purport to arise under the federal securities laws, including those under the Securities Act of 1933, as amended, and/or the Securities Exchange Act of 1934, as amended. To the extent the exclusive forum clause restricts the courts in which holders of our stock may bring claims arising under the federal securities laws, there is uncertainty as to whether a court would enforce the clause. The exclusive forum clause does not mean that holders of FHN’s stock have waived FHN’s obligations to comply with the federal securities laws and the rules and regulations thereunder.

ITEM 2. PROPERTIES

We own or lease no single physical property that we consider to be materially important to our financial condition or results from operations.
Our banking centers (in our Regional Banking segment) and our FHN Financial offices (in our Fixed Income segment), in the aggregate, remain important to our ability to deliver financial services to a large portion of our customers. For many years, banking center usage by customers has slowly declined, and for many years we
have slowly consolidated banking center locations in response to changing utilization patterns. We expect that long-term trend to continue. Information concerning our business locations, including banking centers and FHN Financial offices, at year-end 2019 is provided in Item 1 of this report under the caption “Physical Business Locations” beginning on page 4, which information is incorporated into this Item 2 by this reference.
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 38

In addition to the banking centers and FHN Financial offices mentioned in Item 1, we own or lease other offices and office buildings such as our headquarters building at 165 Madison Avenue in downtown Memphis, Tennessee. Although some of these other offices contain banking centers or FHN Financial offices, primarily they are used for operational and administrative functions. Our
operational and administrative offices are located in several cities where we have banking centers.
At December 31, 2019, we believe our physical properties are suitable and adequate for the businesses we conduct.

FHN is the parent company of First Horizon Bank (formerly First Tennessee Bank National Association ("FTBNA")). First Horizon Bank's principal divisions and subsidiaries operate under the brands of First Horizon Bank, First Horizon Advisors (formerly FTB Advisors), and FHN Financial (formerly FTN Financial or "FTNF"). FHN offers regional banking, wealth management and capital market services through the First Horizon family of companies.

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 primarily in the southeast U.S. and other selected markets. Regional banking also provides investments, wealth management, financial planning, trust services and asset management, mortgage banking, credit card, and cash management.

On November 4, 2019, FHN and IBERIABANK Corporation ("IBKC") announced that they had entered into an agreement and plan of merger under which IBKC will merge with FHN in a merger-of-equals transaction. IBKC, headquartered in Lafayette, Louisiana, has 319 offices in 12 states, mostly in the southern and southeastern U.S., and has reported $31.7 billion of total assets, $24.0 billion in loans, and $25.2 billion in deposits, at December 31, 2019. IBKC's common stock is listed on The NASDAQ Stock Market, LLC under the symbol IBKC. Under the merger agreement, each share of IBKC common stock will be converted into 4.584 shares of FHN common stock. After closing, FHN expects IBKC common shares will be converted into approximately 44 percent of the then-outstanding shares of FHN common stock. The merger agreement requires FHN to expand its board of directors to seventeen persons; after closing, eight board positions will be held by current IBKC directors, and nine will be held by current FHN directors. FHN expects the transaction to close in mid-2020, subject to regulatory approvals, approval by the shareholders of FHN and of IBKC, and other customary closing conditions.
On November 8, 2019, FHN announced an agreement for First Horizon Bank to purchase 30 branches from SunTrust Bank in conjunction with SunTrust Banks, Inc.'s merger with BB&T Corporation, which created Truist Financial Corp. As part of the agreement, FHN will assume approximately $2.4 billion of branch deposits for a 3.40 percent deposit premium and purchase approximately $410 million of branch loans. The branches are in communities in North Carolina (20 branches), Virginia (8
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 46

branches), and Georgia (2 branches). FHN expects the purchase to close in second quarter 2020, subject to customary closing conditions.
On November 30, 2017, FHN completed its merger with Capital Bank Financial Corporation ("CBF") for an aggregate of 92,042,232 shares of FHN common stock and $423.6 million in cash in a transaction valued at $2.2 billion. I n second quarter 2018, FHN canceled 2,373,220 FHN common shares which had been issued but set aside for certain CBF shareholders who had commenced a dissenter appraisal process.
In first quarter 2018, FHN divested two branches, including approximately $30 million of deposits and $2 million of loans. The branches, both in Greeneville, Tennessee, were divested in connection with First Horizon's agreement with the U.S. Department of Justice and commitments to the Board of Governors of the Federal Reserve System, which were entered into in connection with a customary review of FHN's merger with CBF.
In second quarter 2018, FHN sold approximately $120 million UPB of its subprime auto loans. These loans, originally acquired as part of the CBF acquisition, did not fit within FHN's risk profile.
In second quarter 2019, FHN sold a subsidiary acquired as part of the CBF acquisition, that did not fit within FHN's risk profile. The sale resulted in the removal of approximately $25 million UPB of subprime consumer loans from Loans held-for-sale on FHN's Consolidated Statements of Condition.
On April 3, 2017, FHN 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 municipal advisory services to its clients. Coastal’s government-guaranteed loan products were combined with FHN Financial's existing SBA trading activities to establish an additional major product sector for FHN Financial.
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
Effective January 1, 2019, FHN adopted the provisions of ASU 2016-02 "Leases" and related ASUs on a prospective basis which resulted in the recognition of approximately $185 million of lease assets and approximately $204 million of lease liabilities. See Note 1– Summary of Significant Accounting Policies for additional information.
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, 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.
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 47

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 32 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 within the meaning of the Private Securities Litigation Reform Act of 1995 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 directly or indirectly affecting FHN or 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 Tennessee Department of Financial Institutions ("TDFI") and its Commissioner, 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 Office of the Comptroller of the Currency ("OCC"), 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, 2019 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 MD&A, in other parts of this Annual Report to Shareholders, or in FHN's Annual Report on Form 10-K for the period ended December 31, 2019 into which this MD&A has been incorporated, and in exhibits to and documents incorporated into the Form 10-K.
FINANCIAL SUMMARY - 2019 COMPARED TO 2018
FHN reported net income available to common shareholders of $434.7 million, or $1.38 per diluted share, compared to net income of $538.8 million, or $1.65 per diluted share in 2018. In 2019, operating results were impacted by a modest decrease in net interest income and lower noninterest income compared to the prior year. In 2018, operating results were favorably impacted by a $212.9 million pre-tax gain from the sale of FHN’s remaining Visa Class B shares. In 2019, FHN invested in strategic initiatives, which led to restructuring, rebranding and acquisition-related expenses. Various factors that significantly impacted reported earnings in 2019 included the steady economic environment, efficiency initiatives, prudent investments in key markets as well as strength in our countercyclical fixed income business. Strategic transactions are expected to boost growth, returns and profitability.
While the economic environment remained relatively strong in 2019, with GDP growth throughout the year, low unemployment rates, and muted inflation, actions by the Federal Reserve, including three interest rate cuts during 2019, placed pressure on FHN’s net interest income (“NII”) and net interest margin (“NIM”). Profitable balance sheet growth and strong loan and deposit pricing disciplines helped defend FHN's NII and NIM in this challenging interest rate environment. Additionally, FHN effectively leveraged its key countercyclical fixed income business, capitalizing on lower interest rates and market volatility which led to higher profits within fixed income positively impacting fee income in 2019.
FHN continued to execute on strategic priorities in 2019 by focusing on higher returns, profitable balance sheet growth in key markets and specialty areas, transforming the customer experience, and optimizing the expense base. Beginning in 2019, FHN initiated a company-wide review of business practices with the goal of optimizing its expense base to improve profitability which resulted in $39.8 million of restructuring charges. FHN invested in technology and infrastructure with enhanced mobile banking and an improved consumer platform, and enhanced its presence with strategic talent in growth markets. Additionally, FHN’s enhanced focus on efficiency and expense discipline created broad-based cost savings across multiple expense line items. In 2019, management successfully deployed capital through organic loan growth, share repurchases and a dividend increase.
In fourth quarter 2019, FHN unified the legacy business and Capital Bank brands under the First Horizon name. Additionally, capitalizing on strength and balance sheet capacity from the execution of the CBF acquisition, FHN announced a merger of equals with IBERIABANK Corporation, as well as, an agreement for First Horizon Bank to purchase 30 branches from SunTrust Bank. These actions led to the recognition of $21.3 million and $39.0 million, respectively of rebranding and acquisition-related charges in 2019, compared with $97.5 million of acquisition expenses in 2018.
Asset quality trends remained steady in 2019 reflecting steady economic conditions and continued strong credit risk management. The allowance for loan losses increased 11 percent from $180.4 million on December 31, 2018 to $200.3 million on December 31, 2019, primarily driven by commercial loan growth and grade migration. The ratio of annual net charge-offs to average loans were .09 percent for 2019, up slightly from .06 percent for 2018, and the ratio of 30+ delinquencies to total loans declined from .27 percent to .19 percent.
Return on average common equity (“ROCE”) and ROTCE for 2019 were 9.60 percent and 14.71 percent, respectively, compared to 12.75 percent and 20.28 percent in 2018. Return on average assets (“ROA”) was 1.08 percent in 2019 compared to 1.38 percent in 2018. The 2018 metrics were favorably impacted by the third quarter 2018 gain on the sale of FHN's remaining Visa Class B shares. The tangible common equity to tangible assets ratio was 7.48 percent in 2019 compared to 7.15 percent in 2018. Common equity tier 1, Tier 1, Total capital, and Leverage ratios were 9.20 percent, 10.15 percent, 11.22 percent, and 9.04 percent on December 31, 2019, compared to 9.77 percent, 10.80 percent, 11.94 percent, and 9.09 percent, respectively, on December 31, 2018. Total period-end assets increased to $43.3 billion on December 31, 2019 from $40.8 billion on December 31, 2018. Total period-end equity was $5.1 billion on December 31, 2019, up from $4.8 billion on December 31, 2018.
BUSINESS LINE REVIEW - 2019 COMPARED TO 2018
Regional Banking
Pre-tax income within the regional banking segment increased 2 percent to $671.1 million in 2019 from $658.3 million in 2018. The increase in pre-tax income was primarily driven by an increase in fee income and lower expenses, somewhat offset by an increase in loan loss provision expense.
Total revenue increased $16.9 million to $1.5 billion in 2019 driven by an increase in noninterest income. Noninterest income in 2019 increased 6 percent to $329.8 million from $311.8 million in 2018. The increase in noninterest income was largely driven by increases in fees from derivative sales, other service charges, and ATM interchange fees. The increase in ATM interchange fees was primarily driven by the conversion of CBF debit cards to Visa in first quarter 2019. These increases were somewhat offset by lower fees from deposit transactions and cash management activities in 2019 as a result of a decline in NSF fee income and lower cash management fees driven by changes in consumer behavior. NII was flat in 2019 at $1.2 billion.
Provision expense was $66.1 million and $24.6 million in 2019 and 2018, respectively. The increase in provision expense for 2019 was primarily the result of increased reserves due to commercial loan growth, grade migration, three charge-offs, and a relationship that was downgraded in first quarter 2019.
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 48

Noninterest expense decreased 5 percent to $789.0 million in 2019 from $826.3 million in 2018. The decrease in expense was primarily driven by broad-based cost savings across multiple expense categories driven by strategic focus on expense optimization, lower personnel-related expenses and lower FDIC premium expense which decreased in 2019 primarily due to the end of an FDIC assessment surcharge starting with fourth quarter 2018.
Fixed Income
Pre-tax income in the fixed income segment was $67.8 million in 2019 compared to $11.1 million in 2018. The improvement in results in 2019 was driven by higher noninterest income which outpaced an increase in expenses and lower NII.
Noninterest income increased 69 percent, or $113.7 million, to $278.4 million in 2019 from $164.8 million in 2018. Fixed income product revenue increased to $228.4 million in 2019 from $132.3 million in 2018, as average daily revenue (“ADR”) increased to $914 thousand in 2019 from $531 thousand in the prior year. The increase in ADR was largely due to declining interest rates and increased market volatility. Other product revenue increased to $50.0 million in 2019 from $32.5 million in 2018, driven by higher fees from derivative and loan sales and an increase in fees for portfolio advisory services. NII was $26.0 million and $35.8 million in 2019 and 2018, respectively. The decline in NII was due in large part to lower spreads on inventory positions coupled with lower average balances of trading securities compared to the prior year.
Noninterest expense increased 25 percent, or $47.3 million, to $236.7 million in 2019 from $189.4 million in 2018. The expense increase during 2019 was primarily due to higher variable compensation associated with an increase in fixed income product revenue and a $7.5 million net impact related to the resolution of legal matters recognized in 2019.
Corporate
The pre-tax loss for the corporate segment was $195.1 million and $2.9 million for 2019 and 2018, respectively. In third quarter 2018, FHN recognized a $212.9 million pre-tax gain from the sale of Visa Class B shares which positively impacted noninterest income for 2018.
Net interest expense was $40.8 million in 2019 compared to $64.2 million in 2018. Net interest expense was favorably impacted in 2019 by a reduction of market-indexed deposits due to strong lower cost deposit growth in Regional Banking and higher average balances of cash, somewhat offset by lower average balances of investment securities. Noninterest income (including securities gain/losses) was $41.4 million and $239.3 million in 2019 and 2018, respectively. The decrease in noninterest income in 2019 was driven by the previously mentioned $212.9 million gain from the sale of FHN’s remaining Visa shares recognized in 2018. Additionally lower dividend income recognized in 2019 compared to 2018 and a $1.8 million decrease in gains on sales of properties also contributed to the decline in noninterest income. These decreases were partially mitigated by higher deferred compensation income driven by equity market valuations.
Noninterest expense increased to $195.7 million in 2019 from $177.9 million in 2018. The increase in expense for 2019 was primarily driven by $39.8 million of restructuring costs associated with efficiency initiatives, $21.3 million in rebranding expenses, and a $16.1 million increase in deferred compensation expense. Additionally, charitable contributions of $11.0 million made in 2019 also contributed to the overall expense increase in 2019. These increases were somewhat offset by a $58.5 million decrease in acquisition- and integration-related expenses as well as broad-based cost savings driven by strategic-focus on expense optimization compared to the prior year.
Non-Strategic
The non-strategic segment had pre-tax income of $41.9 million in 2019 compared to $47.5 million in 2018. The decrease in pre-tax income was primarily driven by lower revenues, somewhat offset by lower expenses relative to the prior year.
Total revenue decreased to $33.1 million in 2019 from $58.3 million in 2018. NII decreased 44 percent to $28.6 million in 2019, primarily due to continued run-off of the loan portfolios. Noninterest income decreased to $4.5 million in 2019 from $7.0 million in 2018. In 2018, FHN recognized $4.1 million of gains on the reversals of previous valuation adjustments related to the sales and payoff of TRUPS loans recognized within the non-strategic segment compared to $1.1 million of gains on the sale and payoff of TRUPS loans in 2019.
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 49

The provision for loan losses within the non-strategic segment was a provision credit of $19.1 million in 2019 compared to a provision credit of $17.6 million in the prior year. Overall, the non-strategic segment continued to reflect stable performance combined with lower loan balances resulting in a $9.8 million decline in reserves to $17.6 million on December 31, 2019. Losses remain historically low as the non-strategic segment had net recoveries of $9.2 million in 2019 compared to net recoveries of $7.2 million a year ago.
Noninterest expense was $10.2 million in 2019, down from $28.4 million in 2018. The decline in noninterest expense relative to the prior year was primarily the result of an $8.3 million pre-tax expense reversal related to the settlement of litigation matters in 2019. Additionally, lower personnel expenses and legal fees also contributed to the overall decrease in noninterest expense compared to the prior year.
INCOME STATEMENT REVIEW - 2019 COMPARED TO 2018; 2018 COMPARED TO 2017
Total consolidated revenue was $1.9 billion, a 4 percent decrease from the prior year, driven by a decrease in noninterest income and lower net interest income. Total consolidated expenses were $1.2 billion, a 1 percent increase from 2018, primarily driven by restructuring and rebranding expense and higher fixed income variable compensation expense, somewhat offset by lower acquisition- and integration-related expenses and broad-based cost savings across multiple line items driven by strategic focus on expense optimization.
In 2018, total consolidated revenue increased 46 percent, or $610.6 million to $1.9 billion in 2018, driven by a 45 percent increase in NII due to the full-year inclusion of Capital Bank and rate increases and a 47 percent increase in noninterest income primarily due to the gain on the sale of Visa Class B shares. Total consolidated expenses increased 19 percent to $1.2 billion in 2018 from $1.0 billion in 2017. The expense increase was primarily driven by a full-year inclusion of Capital Bank and an increase in acquisition- and integration-related expenses associated with the CBF acquisition.
NET INTEREST INCOME
Net interest income was $1.2 billion in 2019, a 1 percent decrease from 2018. On a fully taxable equivalent ("FTE") basis, NII also decreased 1 percent to $1.2 billion in 2019 compared to 2018. As detailed in Table 1 - Analysis of Changes in Net Interest Income, as an increase in deposit costs and lower loan accretion were mitigated with strong commercial loan and deposit growth and higher loan yields. Average earning assets increased 4 percent to $37.2 billion in 2019 from $35.7 billion in 2018. The increase in average earning assets in 2019 was primarily driven by loan growth. To a much lesser extent an increase in interest-bearing cash also increased average earning assets in 2019, but these increases were somewhat offset by a smaller available-for-sale ("AFS") securities portfolio, a decrease in loans held-for-sale ("HFS") and declines in other earning assets in 2019 relative to the prior year.
Net interest income increased 45 percent to $1.2 billion in 2018 from $842.3 million in 2017. On a FTE basis, NII increased 44 percent to $1.2 billion in 2018 from $855.9 million in 2017. The increase in NII was largely due to loans added through the CBF acquisition including CBF loan accretion. Additionally, the favorable impact of higher interest rates on loans and higher average balances of available-for-sale securities and trading securities also contributed to the increase in NII, but were somewhat offset by the negative impact of higher market interest rates on deposits and other funding sources. Average earning assets increased 30 percent to $35.7 billion in 2018 from $27.5 billion in 2017. The increase in average earning assets in 2018 was primarily due to the full-year inclusion of Capital Bank, organic loan growth within FHN’s regional banking activities, a larger securities portfolio, higher average balances of fixed income trading securities and increases in loans HFS. These increases were somewhat offset by continued run-off of the Non-strategic loan portfolios.

(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 was 3.28 percent in 2019 compared to 3.45 percent in 2018. The net interest spread was 2.90 percent in 2019 compared to 3.15 percent in 2018, and the impact of free funding was 38 basis points and 30 basis points in 2019 and 2018, respectively. The decrease in NIM in 2019 relative to 2018 was largely driven by an unfavorable rate environment and lower loan accretion.
In 2018, the consolidated net interest margin improved to 3.45 percent from 3.12 percent in 2017, largely driven by the result of CBF loan accretion, the positive impact of higher market rates and an increase in average deposits which allowed for reduction in higher cost funding.
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
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 51

cannot be readily compared to that of other bank holding companies. Table 2 - Net Interest Margin details the computation of the net interest margin for the past three years.

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 2020, NIM will also depend on the extent of Federal Reserve interest rate increases, loan accretion levels, and the competitive pricing environment for core deposits.
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 $47.0 million in 2019 compared to $7.0 million in 2018 and $0 million in 2017. The increase in provision expense for 2019 was primarily the result of increased reserves due to commercial loan growth and grade migration. For 2019, FHN's asset quality metrics remained stable. Year-to-date net charge-offs as a percentage of average loans were .09 percent and .06 percent for the years ended December 31, 2019 and 2018, respectively. The ALLL increased $19.9 million from year-end 2018 to $200.3 million as of December 31, 2019. 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 2019 Compared to 2018 in this MD&A.
NONINTEREST INCOME
Noninterest income (including securities gains/(losses)) was $654.1 million in 2019 compared to $722.8 million in 2018 and $490.2 million in 2017. Noninterest income was 35 percent of total revenue in 2019 compared to 37 percent of total revenue in 2018 and 2017. Noninterest income in 2019 was primarily driven by higher fixed income product revenue. Additionally, market-driven increases in deferred compensation income, increases in derivative sales within the Regional Banking and Fixed Income segments, and higher bank fees relative to 2018 also contributed to noninterest income levels in 2019. For 2018, the increase in noninterest income was primarily driven by a gain on the sale of FHN's remaining Visa Class B shares in third quarter 2018, partially offset by a decrease in fixed income sales revenue. To a lesser extent, the full-year inclusion of Capital Bank in 2018 and a $14.3 million loss from the repurchase of equity securities previously included in a financing transaction recognized in 2017 also contributed to the year-over-year increase in noninterest income. The increase was partially offset by a decrease in fixed income sales revenue in 2018. FHN’s noninterest income for the last three years is provided in Table 3 - Noninterest Income. The discussion following provides additional information about various line items reported in the following table.

NM – Not meaningful

(a) | Equity securities gains/(losses) for 2018 relates to the gain on the sale of FHN's remaining Visa Class B shares.

(b) | Amounts are driven by market conditions and are mirrored by changes in deferred compensation expense which is included in employee compensation expense.

(c) | Effective January 1, 2018, FHN adopted ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities” and began recording dividend income from FRB and FHLB holdings in Other income. Prior to 2018, these amounts were included in Interest income on the Consolidated Statements of Income.

Fixed Income Noninterest Income
The major component of fixed income revenue is generated from the purchase and sale of fixed income securities as both principal and agent. 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 increased 66 percent or $110.9 million, to $278.8 million in 2019 from $167.9 million in 2018, largely due to declining interest rates and increased market volatility. Revenue from other products increased 41 percent, or $14.8 million, to $50.4 million in 2019, largely driven by higher fees from derivative and loan sales, as well as an increase in fees for portfolio advisory services.
Fixed income noninterest income decreased 23 percent in 2018 to $167.9 million from $216.6 million in 2017, reflecting lower activity due to challenging market conditions (expected interest rate increases, a flattening yield curve, and low levels of market volatility). Revenue from other products decreased 17 percent, or $7.1 million, to $35.6 million from $42.7 million in 2017, largely driven by a decline in fee income from loan sales, somewhat offset by $4.1 million of gains on the sales and payoff of TRUPS loans in the Non-strategic segment and increases in fees from derivative sales.

Deposit Transactions and Cash Management
Fees from deposit transactions and cash management activities 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 decreased to $131.7 million in 2019 from $133.3 million in 2018. Lower NSF fee income and cash management fees contributed to the year-over-year decrease in fees from deposit transactions and cash management activities in 2019 compared to the prior year. In 2018, deposit transactions and cash management income increased to $133.3 million from $110.6 million in 2017, largely associated with the inclusion of Capital Bank. Fees from deposit transactions and cash management activities were negatively impacted in first quarter 2017 due to changes in consumer behavior and a modification of billing practices, which further contributed to the year-over-year increase in 2018.
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 to $55.5 million in 2019 and $54.8 million in 2018, up from $48.5 million in 2017. The increase was due in large part to the continued growth of FHN’s advisory business and favorable market conditions. An increase in the sales of structured products also contributed to the increase in 2018.
Bank-owned Life Insurance
Income from bank-owned life insurance (“BOLI”) increased to $19.2 million and $19.0 million in 2019 and 2018, respectively, from $15.1 million in 2017. The increases in 2018 and 2019 were driven by higher BOLI policy gains recognized in 2018 and 2019.
Securities Gains/(Losses)
Net securities gain/(losses) were not material in 2019 and 2017 compared to $212.9 million in 2018. The 2018 net gain was primarily related to FHN's sale of its remaining holdings of Visa Class B shares.
Other Noninterest Income
All other income and commissions includes revenues from other service charges, ATM and interchange fees, revenue related to deferred compensation plans (which are mirrored by changes in noninterest expense), mortgage banking (primarily within the non-strategic and regional banking segments), dividend income, letter of credit fees, electronic banking fees, insurance commissions, gains/(losses) on the extinguishment of debt, and various other fees.
Revenue from all other income and commissions increased 46 percent or $35.1 million to $111.0 million in 2019 from $75.8 million in 2018. The increase in all other income and commissions was largely due to a $14.4 million increase in deferred compensation income driven by changes in equity market valuations and increases from derivative sales within the Regional Banking segment. Additionally, increases in other service charges and ATM interchange fees also contributed to the increase in all other income and commissions for 2019. Deferred compensation income fluctuates with changes in the market value of the underlying investments and are mirrored by changes in deferred compensation expense which is included in employee compensation expense. These increases were somewhat offset by a $3.4 million decrease in dividend income and a $2.5 million decrease of gains on sales of properties relative to the prior year.
Revenue from all other income and commissions increased to $75.8 million in 2018 from $43.9 million in 2017. In 2017, FHN recognized a $14.3 million loss from the repurchase of equity securities previously included in a financing transaction which contributed to the year-over-year increase in other noninterest income in 2018. Additionally, effective January 1, 2018, FHN adopted ASU 2016-01, "Recognition and Measurement of Financial Assets and Financial Liabilities" and began recording dividend income from FRB and FHLB holdings in other income which also contributed to the increase in other noninterest income in 2018 relative to the prior year, as previously these amounts were included in Interest income. Increases in mortgage banking income and other service charges related to the full-year inclusion of Capital Bank, $5.5 million in collections from CBF loans that were fully charged off prior to acquisition, and $5.0 million of gains on the sales of properties recognized in 2018 also contributed to the increase in other noninterest income. For 2018, all other income and commissions was unfavorably impacted by a $9.5 million decrease in deferred compensation income.
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 56

NONINTEREST EXPENSE
Total noninterest expense increased 1 percent, or $9.6 million, to $1.2 billion in 2019. The slight increase in noninterest expenses in 2019 was largely driven by restructuring and rebranding expenses and higher fixed income variable compensation. These increases were somewhat offset by lower acquisition-and integration-related expenses compared to 2018 and broad-based cost saving across multiple line items driven by strategic focus on expense optimization.
Total noninterest expense increased 19 percent, or $198.3 million, to $1.2 billion in 2018 from $1.0 billion in 2017. The increase in noninterest expenses in 2018 was primarily due to the full-year inclusion of Capital Bank expenses compared to one month of expenses included in 2017. Higher acquisition- and integration-related expenses primarily associated with the CBF acquisition, higher personnel-related expenses, and a smaller repurchase and foreclosure provision expense reversal related to the settlement of certain repurchase claims in 2018 relative to 2017, also contributed to the expense increase in 2018. A decrease in loss accruals related to legal matters in 2018 favorably impacted expense relative to 2017, offsetting a portion of the overall expense increase.
FHN’s noninterest expense for the last three years is provided in Table 5 - Noninterest Expense. The discussion following provides additional information about various line items reported in the following table.

Employee Compensation, Incentives, and Benefits
Employee compensation, incentives, and benefits (personnel expense), the largest component of noninterest expense, increased 6 percent, or $37.1 million, to $695.4 million in 2019 from $658.2 million in 2018. The increase in personnel expense was primarily driven by an increase in variable compensation associated with higher fixed income sales revenue and severance-related costs associated with restructuring, repositioning, and efficiency initiatives recognized in 2019. Additionally, a $15.7 million increase in deferred compensation expense driven by equity market valuations also contributed to the increase in personnel expense in 2019. These expense increases were somewhat offset by a $6.2 million decrease in acquisition- and integration-related expenses and a reduction in headcount relative to the prior year.
Personnel expense increased 12 percent, or $70.8 million, to $658.2 million in 2018 from $587.5 million in 2017, primarily due to a 30 percent increase in headcount in connection with the CBF acquisition. Within the regional banking segment, personnel expense increased due to a $15 hourly wage floor, strategic hires in expansion markets and specialty areas, and higher incentive expense associated with loan and deposit growth. Personnel expense within the fixed income segment decreased in 2018, largely driven by lower variable compensation associated with lower fixed income sales revenue relative to 2017. Additionally, a $10.3 million decrease in deferred compensation expense in 2018 as well as decreases in special performance, acquisition, and integration-related personnel expenses also offset a portion of the increase in personnel expense in 2018 relative to 2017.
Occupancy
Occupancy expense decreased to $80.3 million in 2019, from $85.0 million in 2018. The decrease in occupancy expense in 2019 was primarily due to lower lease abandonment expense associated with acquisition- and integration-related expenses in 2019 relative to the prior year. Occupancy expense increased to $85.0 million in 2018 from $54.6 million in 2017, primarily driven by higher rental expense due to the full-year inclusion of Capital Bank. Additionally, FHN recognized $5.3 million of acquisition- and integration-related expenses primarily associated with lease abandonment expense in 2018.
Computer Software
Computer software expense was $60.7 million and $60.6 million in 2019 and 2018, respectively. Computer software increased $12.4 million in 2018 to $60.6 million from $48.2 million in 2017. The increase in computer software expense in 2018 was the result of the inclusion of a full-year of Capital Bank (compared to one month in 2017), as well as FHN’s focus on technology-related projects. To a lesser extent, acquisition- and integration-related expenses primarily associated with the CBF acquisition also contributed to the increase in computer software expense for 2018.
Professional Fees
Professional fees increased $9.4 million to $55.2 million in 2019 from $45.8 million in 2018. In 2019, the increase in professional fees was primarily driven by higher restructuring costs associated with the identification of efficiency opportunities within the organization, strategic initiatives and rebranding expenses recognized in 2019, somewhat offset by lower acquisition- and integration-related expenses relative to 2018. Professional fees decreased to $45.8 million in 2018 from $47.9 million in 2017. In 2018, the decrease in professional fees was due to lower acquisition- and integration-related expenses primarily associated with the CBF acquisition relative to 2017, somewhat offset by strategic investments to analyze growth potential and product mix for new markets.
Operations Services
Operations services expense decreased 18 percent, or $10.3 million to $46.0 million in 2019 from $56.3 million in 2018, primarily driven by vendor consolidation following the completion of integration of the CBF merger. Additionally, lower acquisition- and integration-related expenses also contributed to the decrease in 2019 compared to the prior year. Operations services expense was $56.3 million in 2018 compared $43.8 million in 2017. The increase in operations services expense was primarily related to an increase in third party fees associated with the inclusion of Capital Bank operating expenses, as well as higher acquisition- and integration-related expenses primarily related to the CBF acquisition.
Advertising and Public Relations
Expenses associated with advertising and public relations increased to $34.4 million from $24.8 million in 2018 and $19.2 million in 2017. In 2019, FHN recognized higher advertising expense due in large part to FHN’s rebranding initiative, as well
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 58

as promotional branding campaigns and target marketing in new markets. The increase in 2018 relative to 2017 was due in large part to promotional branding campaigns and targeted marketing in new markets.
Equipment Rentals, Depreciation, and Maintenance
Equipment rentals, depreciation, and maintenance expense decreased 13 percent, or $5.1million, to $34.0 million for 2019, from $39.1 million in 2018. The decrease in equipment rentals, depreciation, and maintenance expense in both periods was due in large part to branch optimization, consolidation efforts and planned CBF merger synergies. Equipment rentals, depreciation, and maintenance expense was $39.1 million in 2018 compared to $29.5 million in 2017. The increase in equipment rentals, depreciation, and maintenance expense in was due in large part to the full-year inclusion of Capital Bank in 2018 and higher acquisition- and integration-related expenses primarily related to the CBF acquisition.
Communication and Courier
Expenses associated with communications and courier decreased 16 percent, or $5.0 million, to $25.1 million in 2019 from $30.0 million in 2018, primarily driven by branch optimization, vendor consolidation efforts and planned CBF merger synergies. Additionally, a $1.2 million decrease in acquisition- and integration-related expenses also contributed to the expense decrease in 2019. Expenses associated with communication and courier increased to $30.0 million in 2018 from $17.6 million in 2017, primarily driven by the full-year inclusion of Capital Bank in 2018. To a lesser extent, an increase in acquisition- and integration-related expenses also contributed to the expense increase in 2018.
Amortization of Intangible Assets
Amortization expense was $24.8 million in 2019, compared to $25.9 million in 2018 and $8.7 million in 2017. The increase in amortization expense from 2017 was primarily due to the full-year inclusion of intangibles related to the Capital Bank acquisition in 2018.
FDIC Premium Expense
FD IC premium expense decreased 37 percent, or $11.8 million from $31.6 million in 2018 to $19.9 million in 2019. The decrease in FDIC premium expense is primarily due to the end of an FDIC assessment surcharge starting with fourth quarter 2018. FDIC premium expense increased to $31.6 million in 2018 from $26.8 million in 2017 primarily due to the CBF acquisition, as well as organic growth. In fourth quarter 2018, the FDIC assessment surcharge initiated in third quarter 2016 expired offsetting a portion of the overall increase in FDIC premium expense for 2018.
Legal Fees
Legal fees increased to $16.9 million in 2019 from $11.1 million in 2018 and $12.1 million in 2017. Legal fees fluctuate primarily based on the status, timing, type, and composition of cases or other projects.
Contract Employment and Outsourcing
Expenses associated with contract employment and outsourcing decreased 31 percent, or $5.7 million to $12.9 million in 2019. The decrease was primarily driven by the completion of acquisition- and integration- related projects primarily associated with the CBF acquisition. Expenses associated with contract employment and outsourcing increased 24 percent, or $3.6 million, to $18.5 million in 2018 compared to $15.0 million in 2017, primarily driven by acquisition- and integration-related projects primarily associated with the CBF acquisition.
Other Noninterest Expense
Other expense includes travel and entertainment expense, other insurance and tax expense, customer relations expense, supplies, employee training and dues, miscellaneous loan costs, losses from litigation and regulatory matters, expenses associated with the non-service components of net periodic pension and post-retirement cost, tax credit investments, expenses associated with OREO, expenses/expense reversals associated with FHN’s repurchase and foreclosure provision, and various other expenses.
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 59

All other expense decreased $8.9 million to $126.1 million in 2019 from $135.0 in 2018, primarily due to a $38.3 million decrease in acquisition- and integration-related expenses. FHN’s strategic focus on expense optimization also contributed to the overall decline in other noninterest expense in 2019, but was somewhat offset by a $23.1 million increase in costs associated with restructuring and rebranding initiatives primarily related to assets impairments. Additionally, a $10.8 million increase in charitable contributions, as well as increases in customer relations and loss accruals related to legal matters, somewhat offset a portion of the overall expense decline in 2019.
All other expense was $135.0 million in 2018 compared to $112.6 million in 2017. The increase was primarily due to a $35.8 million increase of acquisition- and integration-related costs primarily associated with the CBF acquisition, including contract termination charges, costs of shareholder matters and asset impairments related to the integration, as well as other miscellaneous expenses. A smaller pre-tax expense reversal of mortgage repurchase and foreclosure provision in 2018 compared to 2017 also contributed to the increase in all other expense in 2018. Additionally, a $4.1 million increase in Visa derivative valuation adjustments recognized in 2018, higher expenses associated with travel and entertainment, supplies, and employee training and dues largely due to the inclusion of Capital Bank, higher pension expense and an increase in the reserve for unfunded commitments also contributed to the increase in other noninterest expense relative to the prior year. These expense increases were largely offset by a $39.9 million net decrease in loss accruals related to legal matters and $8.8 million of charitable contributions made to FHN's foundation in 2017.
INCOME TAXES
FHN recorded an income tax provision of $133.3 million in 2019, compared to $157.6 million in 2018 and $131.9 million in 2017. The effective tax rates for 2019, 2018, and 2017 were approximately 22.8 percent, 22.1 percent, and 42.7 percent, respectively.
The increase in the effective tax rates in 2019 compared to 2018 was related to a $5.1 million decrease in net discrete tax benefits realized during 2019. The larger discrete tax benefit in 2018 was primarily related to trailing benefits from the reduction in the federal corporate income tax rate under the Tax Cuts and Jobs Act “Tax Act,” which lowered the statutory rate to 21 percent from 35 percent effective January 1, 2018.
The decrease in the effective tax rates in 2018 compared to 2017 was primarily driven by the reduction in the federal corporate income tax rate under the Tax Act. The tax rate in 2017 was adversely affected by approximately $82 million of tax expense primarily related to the revaluation of the net deferred tax asset based on a 21 percent tax rate as a result of the passage of the Tax Act in 2017. This was partially offset by the reversal of a capital loss valuation allowance which decreased federal and state taxes by $40.4 million.
The company’s effective tax rate is favorably affected by recurring items such as bank-owned life insurance, tax-exempt income, and tax 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 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, 2019, FHN’s net DTA was $69.0 million compared with $127.9 million at December 31, 2018 and $221.8 million at December 31, 2017.
As of December 31, 2019, FHN had deferred tax asset balances related to federal and state income tax carryforwards of $43.8 million and $1.2 million, which will expire at various dates. Refer to Note 15 - Income Taxes for additional information.
FHN’s gross DTA after valuation allowance was $250.6 million and $254.6 million as of December 31, 2019 and 2018, 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. FHN’s federal
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 60

consolidated tax returns are currently under audit for 2013 through 2015 and the statutes for those years have been extended through December 31, 2020. Federal tax refund claims for Capital Bank Financial Corporation for 2010 - 2012 are under examination by the IRS. Several of FHN’s state returns are currently under examination. See Note 15 - Income Taxes for additional information.
RESTRUCTURING, REPOSITIONING, AND EFFICIENCY INITIATIVES
Beginning in first quarter 2019, FHN initiated a company-wide review of business practices with the goal of optimizing its expense base to improve profitability and create capacity to reinvest savings into technology and revenue production activities. The net charges for restructuring, repositioning, and efficiency initiatives were $39.8 million in 2019, primarily associated with professional fees, asset impairments, and severance and other employee costs. Due to the broad nature of the actions being taken, many components of expense are expected to benefit from the current efficiency initiatives. See Note 25 - Restructuring, Repositioning, and Efficiency for additional information.
STATEMENT OF CONDITION REVIEW - 2019 COMPARED TO 2018
Total period-end assets were $43.3 billion on December 31, 2019, up 6 percent from $40.8 billion on December 31, 2018. Average assets increased 4 percent to $41.7 billion in 2019 from $40.2 billion in 2018. The increase in period-end assets was primarily driven by strong loan growth. Additionally, an increase in securities purchased under agreement to resell and a net increase in non-earning assets (including right-of-use (“ROU”) assets) also contributed to the increase in period-end assets. These increases were somewhat offset by a net decrease in other earning assets (primarily interest-bearing cash), AFS securities, and loans HFS. The increase in average assets was also primarily driven by strong loan growth, somewhat offset by decreases in AFS securities, loans HFS, and a net decrease in other earning assets. Effective January 1, 2019, FHN adopted ASU 2016-02, “Leases” and all related ASUs and began recording ROU lease assets and lease liabilities in Other assets and Other liabilities which contributed to the increase in period-end and average assets and liabilities in 2019 relative to the prior year.
Total period-end liabilities were $38.2 billion on December 31, 2019, a 6 percent increase from $36.0 billion on December 31, 2018, driven by a net increase in short-term borrowings (primarily other short-term borrowings) and lease liabilities, somewhat offset by decreases in term borrowings and deposits. Average liabilities increased 3 percent to $36.8 billion in 2019, from $35.6 billion in 2018. The increase in average liabilities was largely driven by higher deposit levels in 2019 and the addition of lease liabilities, somewhat offset by a net decrease in short-term borrowings in 2019 relative to the prior year.
EARNING ASSETS
Earning assets consist o f loans, investment securities, other earning assets such as trading securities, interest-bearing cash, and loans HFS. Average earning assets increased to $37.2 billion in 20 19 from $35.7 billion in 2018. A more detailed discussion of the major line items follows.
Loans
Period-end loans were $31.1 billion on December 31, 2019, up from $27.5 billion on December 31, 2018. Average loans increased $2.0 billion to $29.2 billion in 2019 from $27.2 billion in 2018. The increase in period-end and average loan balances compared to the prior year was primarily due to strong loan growth within the Regional Banking portfolios.
In third quarter 2019, FHN corrected a previous mis-classification of commercial loans and reclassified approximately $410 million of market investor CRE loans from the C&I portfolio to the CRE portfolio. These loans were identified during an internal review and assessment by management of certain loan populations, a portion of which relate to loans acquired as part of the Capital Bank merger. The reclassification of these loan balances between regional banking portfolios did not have an impact on FHN’s consolidated period-end or average balance sheet and had an immaterial effect on the allowance for loan losses. No adjustments were made to prior periods as the impact of the reclassification, including the effect on the allowance for loan losses was deemed to be immaterial in all periods.
The following table provides detail regarding FHN's average loans.

C&I loans are the largest component of the loan portfolio comprising 63 percent of total loans in 2019 and 58 percent in 2018. C&I loans increased 15 percent, or $2.4 billion, from 2018, largely driven by strong loan growth within the mortgage warehouse lending and commercial portfolios of Regional Banking. Growth in other specialty lending areas within Regional Banking, such as energy and healthcare also meaningfully contributed to the overall growth in average C&I loans in 2019 compared to 2018. Commercial real estate loans experienced a net decrease of 2 percent to $4.1 billion in 2019, primarily driven by loan payoffs and strategic run-off.
Average consumer loans declined 5 percent, or $.3 billion, from 2018 to $6.8 billion in 2019, largely driven by declines in real estate installment loans and home equity lines of credit within the Regional Banking segment, and continued wind-down of portfolios within the Non-strategic segment.
The following table provides a detail of contractual maturities of commercial loans on December 31, 2019.

Because of various factors, the contractual maturities of consumer loans are not indicative of the actual lives of such loans. 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
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 62

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. As a result, 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, 2019 (Amortized Cost) shows information pertaining to the composition, yields, and contractual
maturities of the investment portfolio. Investment securities were $4.5 billion and $4.6 billion on December 31, 2019 and 2018, respectively. Average investment securities were $4.5 billion and $4.7 billion in 2019 and 2018, representing 12 percent and 13 percent of average earning assets in 2019 and 2018, respectively. The decrease in period-end and average investment securities was driven by FHN's reinvestment strategy in 2019. A portion of this decrease was somewhat offset by unrealized gains within the securities portfolio driven by lower interest rates in 2019 relative to the prior year. 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 $4.4 billion and $4.6 billion in 2019 and 2018, respectively. U.S. treasury securities and corporate and municipal bonds averaged $102.4 million in 2019 compared to $76.5 million in 2018. On December 31, 2019, AFS investment securities had $41.3 million of net unrealized gains compared to $100.6 million of net unrealized losses on December 31, 2018. See Note 3 - Investment Securities for additional detail.

Loans Held-for-Sale
Loans HFS consists of small business, other consumer loans, the mortgage warehouse, USDA, student, and home equity loans. The average balance of loans HFS decreased to $578.0 milli on in 2019 from $724.0 million in 2018. On December 31, 2019, loans HFS were $593.8 millio n compared to $679.1 million on December 31, 2018. The decrease in period-end an d average loans HFS was primarily driven by decreases in small business loans, somewhat offset by increases in USDA loans. In second quarter 2019, the sale of a subsidiary resulted in the removal of approximately $25 million UPB of subprime consumer loans which also contributed to the decrease in both period-end and average balances, but was somewhat offset by the remaining UPB related to a mortgage lending relationship that converted to the underlying collateral during third quarter 2019.
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 Federal Reserve and other financial institutions. Other earning assets averaged $2.9 billion and $3.0 billion in 2019 and 2018, respectively, as decreases in asset repos and fixed income trading securities were largely offset by an increase in interest-bearing cash. 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 $2.5 billion and $3.3 billion on December 31, 2019 and 2018, respectively. The decline in other earning assets on a period-end basis was primarily driven by decreases in interest-bearing cash and federal funds sold, somewhat offset by an increase in asset repos. The decrease in interest-bearing cash at year-end 2019 was primarily driven by strong loan growth and balance sheet funding strategies.
The following table summarizes FHN's average other earning assets for 2019, 2018, and 2017.

Non-earning assets
Period-end non-earning assets increased to $4.7 billion on December 31, 2019 from $4.6 billion on December 31, 2018. The increase was due to the recognition of ROU assets associated with the adoption of ASU 2016-02, "Leases," and increases in derivative assets and LIHTC investments, partially offset by decreases in cash and net deferred tax assets.
Deposits
Average deposits were $32.4 billion during 2019, up 5 percent from $30.9 billion during 2018. The increase in average deposits was largely due to FHN's strategic focus on growing deposits. As noted in the table below, the composition of deposits remained relatively consistent in 2019, with interest-bearing deposits comprising 75 percent of total deposits. Market-indexed deposits as a percentage of total deposits decreased from 15 percent in 2018 to 13 percent in 2019, while commercial interest deposits increased as a percentage of total deposits.
Period-end deposits were $32.4 billion on December 31, 2019, down 1 percent from $32.7 billion on December 31, 2018. The decline was primarily due to a decrease in market-indexed deposits which more than offset an influx of consumer interest deposits and non-interest bearing deposits. The following table summarizes FHN's average deposits for 2019, 2018 and 2017.

Short-Term Borrowings
Short-term borrowings (federal funds purchased (“FFP”)), securities sold under agreements to repurchase, trading liabilities, and other short-term borrowings) averaged $2.5 billion in 2019 and $2.8 billion in 2018. As noted in the table below, the decrease in short-term borrowings was largely due to decreases in other short-term borrowings and trading liabilities. 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. Trading liabilities fluctuate based on levels of trading securities and hedging strategies. Federal funds purchases increased in 2019, as an additional source of wholesale funding for FHN's balance sheet
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 64

activities. Period-end short-term borrowings were $4.0 billion on December 31, 2019 and $1.5 billion on December 31, 2018. The increase in period-end short-term borrowings was primarily due to an increase in FHLB borrowings. Additionally, increases in FFP and trading liabilities also contributed to the increase in short-term borrowings on December 31, 2019. FFP fluctuates depending on the amount of excess funding of FHN’s correspondent bank customers. See Note 9 - Short-Term Borrowings for additional information.
The following table summarizes FHN's average short-term borrowings for 2019, 2018 and 2017.

Term Borrowings
Term borrowings include senior and subordinated borrowings with original maturities greater than one year. Average term borrowings were $1.1 billion in 2019 and $1.2 billion in 2018. Term borrowings were $.8 billion on December 31, 2019, down from $1.2 billion on December 31, 2018. The decrease in period-end and average term borrowings was primarily driven by the redemption of $400.0 million senior debt in fourth quarter 2019. See Note 10 - Term Borrowings for additional information.
Other Liabilities
Period-end other liabilities were $1.0 billion on December 31, 2019, up from $.7 billion on December 31, 2018. The increase was primarily due to the recognition of lease liabilities associated with the adoption of ASU 2016-02, "Leases" and an increase in fixed income payables, somewhat offset by a decrease in derivative liabilities.
CAPITAL - 2019 COMPARED TO 2018
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 $5.1 billion on December 31, 2019 from $4.8 billion on December 31, 2018. Average equity increased to $4.9 billion in 2019 from $4.6 billion in 2018. The increase in period-end and average equity was due to net income recognized in 2019, somewhat offset by common and preferred dividends paid and share repurchases (mentioned below). A decrease in accumulated other comprehensive income ("AOCI") also contributed to the increase in period-end and average equity and was largely the result of a decrease in unrealized losses associated with AFS debt securities.

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. Furthermore, beginning January 1, 2019, a capital conservation buffer of 50 basis points above these levels must be maintained on the Common Equity Tier 1, Tier 1 Capital and Total Capital ratios to avoid restrictions on dividends, share repurchases and certain discretionary bonuses. As of December 31, 2019, each of FHN and First Horizon Bank had sufficient capital to qualify as well-capitalized institutions and to meet the capital conservation buffer requirement. For both FHN and First Horizon Bank, the risk-based regulatory capital ratios decreased in 2019 relative to 2018 primarily due to increased risk-weighted assets driven by loan growth which was partially offset by the impact of net income less dividends and share repurchases during in 2019. The Tier 1 leverage ratio was relatively flat for both FHNC and First Horizon Bank as average assets for leverage in fourth quarter of 2019 increased relative to fourth quarter of 2018. During 2020, capital ratios are expected to remain above well-capitalized standards.
Stress Testing
The Economic Growth, Regulatory Relief, and Consumer Protection Act, along with an interagency regulatory statement effectively exempted both FHN and FTBNA from Dodd-Frank Act ("DFA") stress testing requirements starting with 2018.
For 2019, even though no longer required, FHN and First Horizon Bank completed a stress test using DFA scenarios and requirements previously in effect. Results of these tests indicate that both FHN and First Horizon Bank would be able to maintain capital well in excess of Basel III Adequately Capitalized standards under the hypothetical severe global recession of the 2019 DFA Severely Adverse scenario. A summary of those results was posted in the “News & Events-Stress Testing Results” section on FHN’s investor relations website on December 6, 2019. Neither FHN’s stress test posting, nor any other material found on FHN’s website generally, is part of this report or incorporated herein.
First Horizon will continue performing an annual enterprise wide stress test as part of its capital and risk management process. Results of this test will be presented to executive management and the board.
The disclosures in this “Stress Testing” section include forward-looking statements. Please refer to “Forward-Looking Statements” for additional information concerning the characteristics and limitations of statements of that type.

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.
Table 13a—Issuer Purchases of Common Stock - General Authority
On January 23, 2018, FHN announced a $250 million share purchase authority with an expiration date of January 31, 2020. On January 29, 2019, FHN announced a $250 million increase in that authority along with an extension of the expiration date to January 31, 2021. 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. As of December 31, 2019, $229.3 million in purchases had been made under this authority at an average price per share of $15.09, $15.07 excluding commissions. Management currently does not anticipate purchasing a material number of shares under this authority during the first half of 2020 due to the pending merger of equals with IBKC.

Table 13b—Issuer Purchase of Common Stock - Compensation Authority
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. 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. As of December 31, 2019, the maximum number of shares that may be purchased under the program was 24.5 million shares. Management currently does not anticipate purchasing a material number of shares under this authority during 2020.

ASSET QUALITY - TREND ANALYSIS OF 2019 COMPARED TO 2018
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 (20 percent of total loans), the majority of which is in the consumer real estate portfolio (19 percent of total loans). Industry concentrations are discussed under the heading C&I below.
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 executives 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 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. For example, in 2017 FHN expanded its borrower limits in association with the expansion of its overall portfolio through the acquisition of CBF and revised its Portfolio Concentration, Country Exposure, and Automated Clearing House limits to more appropriately align with its overall risk appetite and to provide more granularity into some of its portfolio sub segments. Additionally, in 2019 FHN expanded borrower limits within certain portfolios (such as loans to mortgage companies) to support FHN's strategic plan. 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 an RM and a PM for most commercial credits. The RM is primarily responsible for communications with the customer and maintaining the relationship, while the PM is responsible for assessing the credit quality of the borrower, beginning with the initial underwriting and continuing through the servicing period. 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, more frequent servicing on lower rated borrowers, 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
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 67

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 $20.1 billion on December 31, 2019, 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, 2019, are in Tennessee (31 percent), North Carolina (10 percent), California (9 percent), Texas (6 percent), Florida (6 percent), Georgia (4 percent), and South Carolina (3 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 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, 2019 and 2018. 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.

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 conditi ons. 36 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 “Loans to Mortgage Companies” and “Finance and Insurance”, as discussed below, on December 31, 2019, FHN did not have any other concentrations of C&I loans in any single industry of 10 percent or more of total loans.
Loans to Mortgage Companies
The balance of loans to mortgage companies was 22 percent of the C&I portfolio as of December 31, 2019, and 12 percent of the C&I portfolio as of December 31, 2018, 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. The increase in loans to mortgage companies year over year was due to higher home purchasing and refinance activity, as well as market share growth. In 2019, 60 percent of the loans funded were home purchases and 40 percent were refinance transactions.
Finance and Insurance
The finance and insurance component represents 14 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, 2019, asset-based lending to consumer finance companies represents approximately $1.2 billion of the finance and insurance component.
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. During second quarter 2018, FHN revised the grading approach associated with the TRUPS portfolio to align with its scorecard grading methodologies which resulted in upgrades to a majority of this portfolio. 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, 20 18, one TRUP relationship was on interest deferral. This relationship returned to accrual in fourth quarter 2019.
As of December 31, 2019, the UPB of trust preferred loans totaled $238.4 million ($177.7 million of bank TRUPS and $60.7 million of insurance TRUPS) with the UPB of other bank-related loans totaling $304.6 million. Inclusive of a valuation allowance on TRUPS of $19.1 million, total reserves (ALLL plus the valuation allowance) for TRUPS and other bank-related loans were $19.4 million or 4 percent of outstanding UPB.
C&I Asset Quality Trends
Overall, the C&I portfolio trends remained strong in 2019, continuing in line with recent historical performance. The C&I ALLL increased $23.5 million from December 31, 2018, to $122.5 million as of December 31, 2019. The allowance as a percentage of period-end loans increased to .61 percent as of December 31, 2019, from .60 percent as of December 31, 2018. Nonperforming C&I loans increased $34.5 million from December 31, 2018, to $74.3 million on December 31, 2019, primarily driven by three credits which were partially offset by payments, returns to accrual status, or other resolutions. The nonperforming loan (“NPL”) ratio increased 13 basis points from December 31, 2018, to .37 percent of C&I loans as of December 31, 2019. The 30+ delinquency ratio decreased to .05 percent as of December 31, 2019, from .06 percent as of December 31, 2018. Net charge-offs were $27.0 million in 2019 compared to $11.3 million in 2018, primarily driven by two credits. The following table shows C&I asset quality trends by segment.

Commercial Real Estate
The CRE portfolio was $4.3 billion on December 31, 2019. The CRE portfolio includes both financings for commercial construction and nonconstruction loans. The largest geographical concentrations of balances as of December 31, 2019, are in North Carolina (29 percent), Tennessee (21 percent), Florida (12 percent), Texas (9 percent), South Carolina (8 percent), and Georgia (6 percent), with no other state representing more than 3 percent of the portfolio. This portfolio is segregated between the income-producing CRE and residential CRE classes. The income-producing CRE class contains loans and draws on lines and letters of credit to commercial real estate developers for the construction and mini-permanent financing of income-producing real estate. Subcategories of income CRE consist of office (28 percent), multi-family (20 percent), retail (19 percent), industrial (14 percent), hospitality (11 percent), land/land development (2 percent) and other (6 percent).
The residential CRE class includes loans to residential builders and developers for the purpose of constructing single-family homes, condominiums, and town homes, and on a limited basis, for developing residential subdivisions. Subsequent to the Capital Bank merger completed in 2017, active residential CRE lending is now primarily focused in certain core markets. Nearly all new originations are to “strategic” clients. FHN considers a “strategic” residential CRE borrower as a homebuilder who demonstrates the ability to withstand cyclical downturns, maintains active development and investment activities providing for regular financing opportunities, and is fundamentally sound as evidenced by a prudent loan structure, appropriate covenants and recourse, and capable and willing sponsors in markets with positive homebuilding and economic dynamics.
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
T he CRE portfolio had continued stable performance as of December 31, 2019. The allowance increased $4.8 million from December 31, 2018, to $36.1 million as of December 31, 2019, driven by organic loan growth. Allowance as a percentage of loans increased 5 basis points from December 31, 2018, to .83 percent as of December 31, 2019. Nonperforming loans decreased $1.2 million from December 31, 2018, to $1.8 million as of December 31, 2018. Nonperforming loans as a percentage of total CRE loans decreased 3 basis points from 2018 to .04 percent as of December 31, 2019. Accruing delinquencies as a percentage of period-end loans decreased to .02 percent as of December 31, 2019, from .06 percent as of December 31, 2018. FHN recognized net charge-offs of $.7 million in 2019 compared $.4 million in 2018. The following table shows commercial real estate asset quality trends by segment.

CONSUMER LOAN PORTFOLIOS
Consumer Real Estate
The consumer real estate portfolio was $6.0 billion on December 31, 2019, and is primarily composed of home equity lines and installment loans. The largest geographical concentrations of balances as of December 31, 2019, are in Tennessee (54 percent), North Carolina (15 percent), Florida (13 percent), and California (3 percent), with no other state representing more than 3 percent of the portfolio. As of December 31, 2019, approximately 83 percent of the consumer real estate portfolio was in a first lien position. As of December 31, 2019, the weighted average FICO score at origination of this portfolio was 755 and the refreshed FICO scores averaged 753, compared to 753 and 752, respectively, as of December 31, 2018. As of December 31, 2019, approximately $.9 billion, or 15 percent, of the consumer real estate portfolio consisted of stand-alone second liens while $.1 billion, or 2 percent, were second liens whose first liens are owned or serviced by FHN. FHN obtains first lien performance information from third parties and through loss mitigation activities, and places 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 $1.3 billion of the consumer real estate portfolio as of December 31, 2019. 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, 2019, approximately 76 percent of FHN's HELOCs were in the draw period compared to 72 percent as of December 31, 2018. Based on when draw periods are scheduled to end per the line agreement, it is expected that $315.1 million, or 32 percent of HELOCs currently in the draw period, will enter the repayment period during the next 60 months. Generally, delinquencies 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 monitored closely for those nearing the end of the draw period and borrowers are initially 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.

Underwriting
For the majority of loans in this portfolio, underwriting decisions are made through a centralized loan underwriting center. To obtain a consumer real estate loan, the loan applicant(s) in most cases must first meet a minimum 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 2019 despite deterioration in the non-strategic segment of some metrics compared to prior year. The non-strategic segment is a run-off portfolio and while the absolute dollars of nonaccruals declined compared to December 31, 2018, nonperforming loans ratios deteriorated. That trend of increasing deterioration of ratios 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 $6.8 million from December 31, 2018, to $19.6 million as of December 31, 2019, with the majority of the decline attributable to the non-strategic segment. The balance of nonperforming loans decreased $11.3 million to $71.3 million on December 31, 2019. Loans delinquent 30 or more days and still accruing decreased from $46.5 million as of December 31, 2018, to $36.6 million as of December 31, 2019. The portfolio realized net recoveries of $9.2 million in 2019 compared to net recoveries of $10.3 million in 2018. The following table shows consumer real estate asset quality trends by segment.

Permanent Mortgage
The permanent mortgage portfolio was $.2 billion on December 31, 2019. 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 pre-2009 mortgage businesses. 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 27 percent of loan balances as of December 31, 2019, are in California, but the remainder of the portfolio is somewhat geographically diverse. Non-strategic and corporate segment run-off primarily contributed to the $52.1 million decrease in permanent mortgage period-end balances from December 31, 2018, to December 31, 2019.
Permanent Mortgage Asset Quality Trends
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 portfolios shrink and some of the stronger borrowers payoff or refinance elsewhere. The ALLL decreased $2.2 million as of December 31, 2019, from $11 million as of December 31, 2018. TDR reserves (which are estimates of losses for the expected life of the loan) comprise 88 percent of the ALLL for the permanent mortgage portfolio as of December 31, 2019. Consolidated accruing delinquencies decreased $.8 million from December 31, 2018 to $6.3 million as of December 31, 2019. Nonperforming loans decreased $7.4 million from December 31, 2018, to $14.3 million as of December 31, 2019. The portfolio experienced net recoveries of $2.8 million in 2019 compared to net recoveries of $.9 million in 2018. The following table shows permanent mortgage asset quality trends by segment.

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 increased to $200.3 million on December 31, 2019, from $180.4 million on December 31, 2018. The ALLL as of December 31, 2019, 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 .64 percent on December 31, 2019, from .66 percent on December 31, 2018.
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. Provision expense was $47.0 million in 2019 compared to $7.0 million in 2018. The increase in provision expense was primarily the result of increased reserves due to commercial loan growth, grade migration, two charge-offs, and a relationship that was downgraded in first quarter 2019.
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 portfolios continue to shrink, with stronger credits exiting the portfolios more rapidly than others. Continued stabilization in performance of the consumer real estate portfolio assumes an ongoing positive economic outlook as consumer delinquency and loss rates are correlated with life events that affect borrowers' finances, unemployment trends, and strength of the housing market.
Effective January 1, 2020, FHN adopted the provisions of ASU 2016-13, "Measurement of Credit Losses on Financial Instruments," and related ASUs. Refer to Note 1 - Summary of Significant Accounting Policies for additional information about the standard and its impact on FHN.
Consolidated Net Charge-offs
Net charge-offs were $27.1 million in 2019 compared to $16.1 million in 2018.
The commercial portfolio experienced $27.7 million of net charge-offs in 2019 compared to $11.7 million in 2018. Commercial charge-offs were driven by a $9.2 million partial charge-off on an energy credit and a $7.8 million partial charge-off on a healthcare credit. In addition, the consumer portfolio experienced $.6 million of net recoveries in 2019 compared to $4.4 million of net charge-offs in 2018. The net decrease in consumer portfolio net charge-offs was driven by the credit card and other portfolio.

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”).
Total nonperforming assets (including NPLs HFS) increased to $181.9 million on December 31, 2019, from $175.5 million on December 31, 2018. The nonperforming assets ratio (nonperforming assets excluding NPLs HFS to total period-end loans plus OREO and other assets) was .57 percent as of December 31, 2019, compared to .62 percent as of December 31, 2018.
The ratio of the ALLL to NPLs in the loan portfolio was 1.24 times as of December 31, 2019, compared to 1.22 times as of December 31, 2018. 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.

The following table provides an activity rollforward of OREO balances for December 31, 2019 and 2018. The balance of OREO, exclusive of inventory from government insured mortgages, decreased to $15.7 million as of December 31, 2019, from $22.4 million as of December 31, 2018, driven by the sale of OREO, primarily those acquired from CBF. 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 $21.9 million on December 31, 2019, compared to $32.5 million on December 31, 2018. Loans 30 to 89 days past due decreased to $36.1 million on December 31, 2019, from $42.7 million on December 31, 2018.
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 Federal banking regulators for loans classified as substandard. Potential problem assets in the loan portfolio were $346.9 million on December 31, 2019, compared to $317.0 million on December 31, 2018. The increase year-over-year in potential problem assets was due to a net increase in classified commercial loans within the C&I portfolio. 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.

Troubled Debt Restructuring and Loan Modifications
As part of FHN’s ongoing risk management practices, FHN attempts to work with borrowers when appropriate to extend or modify loan terms to better align with their current ability to repay. Extensions and modifications to loans are made in accordance with internal policies and guidelines which conform to regulatory guidance. Each occurrence is unique to the borrower and is evaluated separately. 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.
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 85

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 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 might 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, 2019 and December 31, 2018, FHN had $206.3 million and $228.2 million portfolio loans classified as TDRs, respectively. For TDRs in the loan portfolio, FHN had loan loss reserves of $19.7 million and $27.7 million, or 10 and 12 percent of TDR balances, as of December 31, 2019 and December 31, 2018, respectively. Additionally, FHN had $51.1 million and $57.8 million of HFS loans classified as TDRs as of December 31, 2019 and December 31, 2018, respectively. Total held-to-maturity TDRs decreased by $21.9 million with the decline attributable to consumer real estate and permanent mortgage partially offset by an increase in commercial.

RISK MANAGEMENT
FHN derives revenue from providing services and, in many cases, assuming and managing risk for profit which exposes the Company to business strategy and reputational, interest rate, liquidity, market, capital adequacy, operational, compliance, and credit risks that require ongoing oversight and management. 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.

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

FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 88

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. 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, which section is incorporated into this MD&A by this reference.
FHN’s market risk appetite is approved by the Executive & Risk Committee of the Board of Directors and executed through management policies and procedures of ALCO and the FHN 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 used 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.
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 89

A summary of FHN's VaR and SVaR measures for 1-day and 10-day time horizons is as follows:

SVaR |  | 9,191 |  |  | 11,918 |  |  | 6,576 |  |  | 8,881 |

VaR |  | 3,735 |  |  | 5,124 |  |  | 2,601 |  |  | 3,258 |
SVaR |  | 24,762 |  |  | 32,343 |  |  | 16,257 |  |  | 21,621 |

FHN’s overall VaR measure includes both interest rate risk and credit spread risk. Separate measures of these component risks are as follows:
Table 28—Schedule of Risks Included in VaR

|  | As of December 31, 2019 |  | As of December 31, 2018
(Dollars in thousands) |  | 1-day |  | 10-day |  | 1-day |  | 10-day
Interest rate risk |  | $ | 693 |  |  | $ | 3,929 |  |  | $ | 618 |  |  | $ | 1,514 |
Credit spread risk |  | 417 |  |  | 828 |  |  | 394 |  |  | 596 |

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.
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 customers, the early withdrawal options held by 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, 2019, NII exposures over the next 12 months assuming rate shocks of plus 25 basis points, 50 basis points, 100 basis points, and 200 basis points are estimated to have favorable variances of .5 percent, .8 percent, 2.1 percent, and 3.5 percent, respectively compared to base NII. A steepening yield curve scenario where long-term
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 90

rates increase by 50 basis points and short-term rates are static, results in a favorable NII variance of .7 percent. A flattening yield curve scenario where long-term rates decrease by 50 basis points and short-term rates are static, results in an unfavorable NII variance of 1.1 percent. Rate shocks of minus 25 basis points and 50 basis points result in unfavorable NII variances of 1.0 percent and 2.7 percent. 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.
During the past few years, the movement of short term interest rates higher after a prolonged period of very low interest rates has had an overall positive effect on FHN's NII and NIM. More recently, the Federal Reserve has lowered short term interest rates. However, competitive pressures have caused FHN’s deposit costs to fall slower than the long term “through the cycle” assumptions made in its simulation model. Of the many assumptions made in its simulation model, deposit pricing and deposit mix are two that can have a meaningful impact on measured results. For example, in the analysis presented above, interest bearing deposit rates are assumed to decrease by 25 basis points in the -50 basis point scenario. If interest bearing deposit costs were to decline 5 percent less than currently assumed in the -50 basis point scenario, the 2.7 percent unfavorable variance in NII disclosed above for that scenario would deteriorate to a 2.9 percent unfavorable variance.
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 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 RISK 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

FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 91

• | Program Governance

• | Fiduciary

• | Financial Crimes (including Bank Secrecy Act, know your customer, security, and fraud)

• | 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, FHN 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, 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 which 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 able to be 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 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.
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 cap acity at the F HLB ($3.4 billion was available at December 31, 2019), 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 98 percent on December 31, 2019 compared to 100 percent on December 31, 2018.
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 correspondent bank 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 First Horizon Bank 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, First Horizon Bank 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. First Horizon Bank early redeemed the $400 million senior debt on November 1, 2019.
Both FHN and First Horizon Bank 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, 2019, First Horizon Bank 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 First Horizon Bank 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 First Horizon Bank 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 First Horizon Bank to declare preferred or common dividends without prior regulatory approval in an aggregate amount equal to First Horizon Bank’s retained net income for the two most recent completed years plus the current year to date. For any period, First Horizon Bank’s
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 92

‘retained net income’ generally is equal to First Horizon Bank’s regulatory net income reduced by the preferred and common dividends declared by First Horizon Bank. Applying the dividend restrictions imposed under applicable federal and state rules as outlined above, the Bank’s total amount available for dividends was $331.2 million as of January 1, 2020. Consequently, on that date the Bank could pay common dividends up to that amount to its sole common stockholder, FHN, or to its preferred shareholders without prior regulatory approval. First Horizon Bank declared and paid common dividends to the parent company in the amount of $345.0 million in 2019 and $420.0 million in 2018. In January 2020, First Horizon Bank declared and paid a common dividend to the parent company in the amount of $65 million. During 2019 and 2018, First Horizon Bank declared and paid dividends on its preferred stock quarterly. Additionally, First Horizon Bank declared preferred dividends in first quarter 2020 payable in April 2020.
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 First Horizon Bank. Beginning January 1, 2019, FHN and First Horizon Bank each must maintain a capital conservation buffer or else face dividend restrictions. The buffer is an extra one-half percent above well-capitalized levels (equal to an extra 2.5 percent above minimum levels) for each of three capital ratios: Common Equity Tier 1, Tier 1, and Total Capital. The restrictions would apply to FHN or First Horizon Bank if the buffer is not met for any of those ratios. Additionally, banking regulators 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 $.14 per common share on January 2, 2020, and in January 2020 the Board approved a $.15 per common share cash dividend payable on April 1, 2020, to shareholders of record on March 13, 2020. FHN paid a cash dividend of $1,550.00 per preferred share on January 10, 2020, and in January 2020 the Board approved a $1,550.00 per preferred share cash dividend payable on April 10, 2020, to shareholders of record on March 26, 2020.
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.

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, 2019, 2018, and 2017. The level of cash and cash equivalents decreased $138.4 million during 2019 compared to a decrease of $46.7 million during 2018 and an increase of $414.3 million in 2017.
Net cash used by investing activities was $2.4 billion in 2019, largely driven by an increase in loan balances somewhat offset by a decrease in interest-bearing cash and a net decrease in AFS debt securities, as maturities and sales outpaced purchases. Net cash provided by financing activities was $1.4 billion in 2019, primarily driven by an increase in short-term borrowings somewhat offset by a decrease in term borrowings, deposits, share repurchases and cash dividends paid during 2019. The increase in short-term borrowings was primarily the result of an increase in FHLB borrowings, which fluctuate largely based on loan demand, deposit levels and balance sheet funding strategies. The decrease in term borrowing was primarily the result of FHN's redemption of $400 million of senior debt during fourth quarter 2019. Net cash provided by operating activities was $830.3 million in 2019 due in large part to net cash inflows of $1.4 billion related to a decrease in fixed income trading securities and favorably driven cash-related net income items. Cash outflows of $1.3 billion related to loans HFS negatively impacted operating cash flows during 2019 as purchases of government guaranteed loans outpaced sales, including the sale of approximately $25 million UPB of subprime consumer loans in 2019.
Net cash used in financing activities was $761.4 million in 2018, driven by a decrease in short-term borrowings and to a lesser extent cash dividends paid and share repurchases, somewhat offset by an increase in deposits. The decrease in short-term borrowings was primarily the result of a decline in FHLB borrowings. The increase in deposits was due in large part to increases in savings and time deposits as a result of FHN's strategic focus on growing deposits. Net cash provided by investing activities was $480.4 million in 2018, driven by proceeds from the sales of FHN's remaining Visa Class B shares and net decreases in the AFS and loan portfolios. Proceeds from the sales and payoffs of TRUPS loans and OREO during 2018 also favorably impacted cash flows in 2018. A decrease in interest-bearing cash, cash paid associated with the cancellation of common shares in connection with CBF dissenting shareholders, and cash paid related to the divestiture of two branches negatively impacted investing cash flows during 2018. Net cash provided by operating cash flows was $234.3 million in 2018. A $1.0 billion net decrease in fixed income trading activities and favorably driven cash-related net income items positively impacted operating cash flows in 2018, but were somewhat offset by cash outflows of $1.4 billion related to a net increase in
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 94

loans HFS, as purchases of government guaranteed loans outpaced sales, including the sale of approximately $120 million of subprime auto loans.
Net cash provided by financing activities was $1.8 billion in 2017, largely driven by 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 cash dividends. Net cash used by investing activities was $1.3 billion in 2017 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 $28.8 million in 2017 as operating cash flows 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 $223.8 million net decrease in operating assets and liabilities.
REPURCHASE OBLIGATIONS, OFF-BALANCE SHEET ARRANGEMENTS, AND OTHER CONTRACTUAL OBLIGATIONS
Obligations from Pre-2009 Mortgage Businesses
Prior to September 2008 FHN originated loans through its pre-2009 mort gage 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 government-sponsored entities, or "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 First Horizon 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 First Horizon proprietary securitizations. In addition to First Horizon proprietary securitization and other whole loan sales activities, FHN also originated and sometimes sold or securitized second-lien, line of credit, and government-insured mortgage loans.
From these pre-2009 activities, FHN has incurred substantial losses stemming from obligations to repurchase loans, pay make-whole amounts, or otherwise resolve claims that loans which FHN originated, or FHN's servicing of those loans, were deficient in a manner for which FHN was liable. Many years ago, FHN established a repurchase and foreclosure liability, or reserve, in connection with those claims. FHN has settled many claims, and the reserve is reduced each time a claim is settled. As discussed in Note 17 - Contingencies and Other Disclosures, FHN's principal remaining exposures for those activities relate to (i) indemnification claims by underwriters, loan purchasers, and other parties which assert that FHN-originated loans caused or contributed to losses which FHN is legally obliged to indemnify, and (ii) indemnification or other claims related to FHN's servicing of pre-2009 mortgage loans.
Servicing Obligations
FHN's national servicing business was sold as part of the platform sale in 2008. A significant amount of mortgage servicing rights ("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 including a subservicing arrangement initiated in 2011 (the "2011 subservicer"). In fourth quarter 2013 and first quarter 2014, FHN sold and transferred a substantial majority of its remaining servicing obligations and servicing assets (including advances) to the 2011 subservicer. 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.
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.
Repurchase Accrual Methodology
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
In determining potential loss content, claims are analyzed by purchaser, vintage, and claim type. FHN considers various inputs including claim rate estimates, historical average repurchase and loss severity rates, mortgage insurance cancellations, and mortgage insurance curtailment requests. Inputs are applied to claims in the active pipeline, as well as to historical average inflows to estimate loss content related to potential future inflows. 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 accruals to cover estimated loss content in the active pipeline (consisting of mortgage loan repurchase, make-whole, foreclosure/servicing demands and certain related exposures), estimated future inflows, and estimated loss content related to certain known claims not currently included in the active pipeline. The
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 95

liability contemplates repurchase/make-whole and damages obligations and estimates for probable incurred losses associated with loan populations excluded from the settlements with the GSEs, as well as other whole loans sold, mortgage insurance cancellations rescissions, and loans included in bulk servicing sales effected prior to the settlements with the GSEs. 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. The repurchase and foreclosure liability decreased to $14.5 million on December 31, 2019 from $32.3 million on December 31, 2018, primarily driven by a $12.6 million payment related to a complete settlement with a single party during second quarter 2019.
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, 2019, the annual measurement date, pension obligations (representing the present value of estimated future benefit payments), including obligations of the unfunded plans, were $835.9 million with $826.1 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 2019 of 3.31 percent for the qualified pension plan and 3.08 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, 2019, 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 made no contributions to
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 96

the qualified pension plan in 2019 and 2017, and made an insignificant contribution to the qualified pension plan in 2018. Management does not currently anticipate that FHN will make a contribution to the qualified pension plan in 2020.
The nonqualified pension plans and other postretirement benefit plans, excluding the retiree medical plan, are unfunded. Benefit payments under the non-qualified plans were $5.2 million in 2019. FHN anticipates 2020 benefit payments to be $5.2 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, 2019. 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.

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. and global economy and outlook, government actions affecting interest rates, political uncertainty, and potential changes in federal policies including changes to the government's approach to tariffs and the potential impact to our customers. In addition, pre-2009 mortgage business matters in the Non-strategic segment could continue to impact FHN’s quarterly 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 including realization of expense efficiencies from the merger with CBF and investing in revenue-producing activities, customer-facing technology, and critical infrastructure. 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. and global economy and outlook. Furthermore, FHN may be indirectly impacted by global events that impact our customers and their businesses. The most recent recession ended in 2009. During the U.S. economic expansion since 2009, growth was muted compared to earlier recoveries. In the past several years, growth has been more robust and more volatile, impacted (up or down) by several significant events such as U.S. tax and regulatory reform, protracted U.S. tariffs and trade negotiations with major foreign trading partners, and, in 2019, an abrupt change in U.S. interest rate policy. Because few expansions last longer than ten years, it is uncertain how much longer the current expansion will continue even though, currently, indications of impending weakness are modest and mixed.
In 2018, the Federal Reserve raised short-term interest rates by .25 percent four times following similar, but less frequent, raises starting in 2015. These actions, along with a decline in long-term interest rates, flattened the yield curve. Early in 2019, the Federal Reserve signaled the possibility of pausing further increases in short-term interest rates while economic trends were evaluated. The Federal Reserve implemented .25 percent cuts to short-term interest rates three times during 2019. This volatility in 2019 contributed to improved performance in mortgage warehouse lending in the Regional Banking segment and FHN's Fixed Income segment. In 2020, lowered rates will put downward pressure on FHN's net interest margin, and 2019's volatility may abate. However, current expectations that rates are stable, at current (relatively low) levels, appear to have benefited the economy by, at a minimum, removing 2018's threat of rising rate.
In 2017, the Chief Executive of the United Kingdom Financial Conduct Authority, which regulates the London InterBank Offered Rate (“LIBOR”), announced that it intends to halt persuading or compelling banks to submit rates for the calculation of LIBOR after 2021. As a result, LIBOR as currently operated may not continue after 2021. FHN is not currently able to predict the impact that the transition from LIBOR will have on the Company; however, because FHN has instruments with floating rate terms based on LIBOR, FHN may experience increases in interest, dividends, and other costs relative to these instruments subsequent to 2021. Additionally, the transition from LIBOR could impact or change FHN’s hedge accounting practices. FHN has initiated efforts to 1) develop an inventory of affected loans, securities, and derivatives, 2) evaluate and draft modifications as needed to address loans outstanding at the time of LIBOR retirement, 3) obtain an understanding of the potential effects for applicable securities and derivatives and 4) assess revisions to product pricing structures based on alternative reference rates. Both the FASB and IRS have released proposals that are intended to facilitate the transition of existing contracts from LIBOR to new reference rates without triggering modification accounting for those contracts. Each proposal contains specific guidance that must be met in order to qualify for the beneficial transition approach and FHN is considering this guidance in its transition plans.
Lastly, while FHN has resolved most matters from the pre-2009 mortgage business, some remain unresolved. The timing or financial impact of resolution of these matters 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 pre-2009 mortgage business 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 pre-2009 mortgage business matters remains.
Foreclosure Practices
FHN retains exposure for potential deficiencies in servicing related to its pre-2009 mortgage servicing business and subservicing arrangements. Further details regarding these matters are provided in "Obligations from Pre-2009 Mortgage Businesses - Servicing Obligations" under "Repurchase Obligations, Off-Balance Sheet Arrangements, and Other Contractual Obligations."

CRITICAL ACCOUNTING POLICIES
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. 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
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 99

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.
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 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
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 100

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.

GLOSSARY OF SELECTED FINANCIAL TERMS
Adjusted Tangible Common Equity to Risk Weighted Assets (“TCE/RWA”) - Common equity excluding intangible assets and unrealized gains/(losses) on available-for-sale securities divided by risk weighted assets.
Allowance for Loan Losses (“ALLL”) - Valuation reserve representing the amount considered by management to be adequate to cover estimated probable incurred losses in the loan portfolio.
Agencies - In this annual report, Agencies are collectively GSEs plus GNMA.
Basis Point - The equivalent of one-hundredth of one percent. One hundred basis points equals one percent. This unit is generally used to measure spreads and movements in interest yields and rates and in measures based on interest yields and rates.
Book Value Per Common Share - A ratio determined by dividing common equity at the end of a period by the number of common shares outstanding at the end of that period.
Commercial and Standby Letters of Credit - Commercial letters of credit are issued or confirmed by an entity to ensure the payment of its customers’ payables and receivables. Standby letters of credit are issued by an entity to ensure its customers’ performance in dealing with others.
Commitment to Extend Credit ("Unfunded Commitments") - Agreements to make or acquire a loan or lease as long as agreed-upon terms (e.g., expiration date, covenants, or notice) are met. Generally these commitments have fixed expiration dates or other termination clauses and may require payment of a fee.
Common Equity Tier 1 - A measure of a company's capital position under U.S. Basel III capital rules, which includes common equity less goodwill, other intangibles and certain other required regulatory deductions as defined in those rules.
Core Businesses - Management treats regional banking, fixed income, and corporate as FHN's core businesses. Non-strategic has significant pre-2009 mortgage businesses assets and operations that are being wound down.
Core Deposits - Core deposits consist of all interest-bearing and noninterest-bearing deposits, except brokered deposits and certificates of deposit over $250,000. They include checking interest deposits, money market deposit accounts, time and other savings, plus demand deposits.
Derivative Financial Instrument - A contract or agreement whose value is derived from changes in interest rates, foreign exchange rates, prices of securities or commodities, or financial or commodity indices.
Diluted Earnings/(Loss) Per Common Share (“Diluted EPS”) - Net income/(loss) available to common shareholders, divided by weighted average shares outstanding plus the effect of common stock equivalents that have the potential to be converted into common shares.
Discharged Bankruptcies - Residential real estate secured loans where the borrower has been discharged from personal liability through bankruptcy proceedings. Such loans that have not been reaffirmed by the borrower are charged down to estimated collateral value less disposition costs (net realizable value) and are reported as nonaccruing TDRs.
Discounted Cash Flow (“DCF Method”) - A valuation method based on the present value of expected future payments discounted at the loan’s effective interest rate.

REPORT OF MANAGEMENT
ON INTERNAL CONTROL OVER FINANCIAL REPORTING
Management at First Horizon National Corporation is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. 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, 2019. 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, 2019.
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.
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 115

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, 2019, 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, 2019, 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, 2019 and 2018, 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, 2019, and the related notes (collectively, the consolidated financial statements), and our report dated February 27, 2020 expressed an unqualified opinion on those consolidated financial statements.
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.

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, 2019 and 2018, 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, 2019, 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, 2019 and 2018, and the results of its operations and its cash flows for each of the years in the three‑year period ended December 31, 2019, 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, 2019, 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 27, 2020 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.
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.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgment. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Assessment of the allowance for loan losses related to loans collectively evaluated for impairment
As discussed in Notes 1 and 5 to the consolidated financial statements, the Company's allowance for loan losses related to loans collectively evaluated for impairment (Collective ALLL) was $172,426 thousand of the total allowance for loan losses of $200,307 thousand at December 31, 2019. The Company estimated the Collective ALLL using historical net loss factors by grade level, loan product, and business segment for commercial loans; and segmented roll-rate models that incorporate various factors that include historical delinquency trends, experienced loss frequencies, and experienced loss severities for consumer loans. The Company subjected the historical net loss factors to qualitative adjustments to reflect current events, trends, and conditions (including economic considerations and trends), which are not fully captured in the historical net loss factors.
We identified the assessment of the Collective ALLL as a critical audit matter because there is a high degree of subjectivity in performing procedures over key factors and assumptions used in the Collective ALLL methodology which included (1) the average amount of time it takes for a loss to be confirmed after a loss event has occurred (loss emergence period), (2) the historical data period used to estimate loss rates, and (3) the internal commercial loan grades. The loss emergence period,
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 117

historical data period used to estimate loss rates, and internal commercial loan grades were challenging to test as the Collective ALLL is sensitive to changes in those assumptions. The assessment of internal commercial loan grades required the use of significant judgment as well as industry knowledge and experience. There was a high level of subjectivity in performing test procedures related to internal and external factors used to estimate the qualitative adjustments. In addition, auditor judgment was required to evaluate the sufficiency of audit evidence obtained.
The primary procedures we performed to address this critical audit matter included the following. We tested certain internal controls over the Company's Collective ALLL process, including controls to (1) develop and approve the Collective ALLL methodology, (2) determine the key factors and assumptions, (3) develop the qualitative factors, and (4) evaluate the estimate in total. We involved credit risk professionals with specialized skills and knowledge who assisted in:

• | performing a methodology assessment and to evaluate that the Company’s methodology is sufficiently structured, transparent, and repeatable to produce a U.S. generally accepted accounting principles compliant estimate;

• | evaluating the key factors and assumptions, specifically the loss emergence period, historical data period used to estimate loss rates, and internal and external factors;

• | performing credit file evaluations on a selection of loans to assess the commercial loan grades;

• | evaluating the methodology and metrics used by the Company to assess internal and external factors related to qualitative adjustments; and

• | performing sensitivity analyses over the effect of internal and external factors to assess their impact on the qualitative component of the Collective ALLL.

We evaluated the cumulative results of the procedures performed to assess the sufficiency of the audit evidence obtained related to the Collective ALLL.
We have served as the Company’s auditor since 2002.

Notes to the Consolidated Financial Statements
Table of Contents
Note 1 – Summary of Significant Accounting Policies
Basis of Accounting. The consolidated financial statements of First Horizon National Corporation (“FHN”), including its subsidiaries, have been prepared in conformity with accounting principles generally accepted in the United States of America and follow general practices within the industries in which it operates. This preparation requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. These estimates and assumptions are based on information available as of the date of the financial statements and could differ from actual results.
Principles of Consolidation and Basis of Presentation. The consolidated financial statements include the accounts of FHN and other entities in which it has a controlling financial interest. Variable Interest Entities (“VIEs”) for which FHN or a subsidiary has been determined to be the primary beneficiary are also consolidated. 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, certain benefit plan balances, and starting in 2019 certain lease-related assets and liabilities) 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.
Revenues. Revenue is recognized when the performance obligations under the terms of a contract with a customer are satisfied in an amount that reflects the consideration FHN expects to be entitled. FHN derives a significant portion of its revenues from fee-based services. Noninterest income from transaction-based fees is generally recognized immediately upon completion of the transaction. Noninterest income from service-based fees is generally recognized over the period in which FHN provides the service. Any services performed over time generally require that FHN render services each period and therefore FHN measures progress in completing these services based upon the passage of time and recognizes revenue as invoiced.
Following is a discussion of FHN's key revenues within the scope of Accounting Standards Update ("ASU") 2014-09, "Revenue from Contracts with Customers", and all related amendments, except as noted.
Fixed Income. Fixed income includes fixed income securities sales, trading, and strategies, loan sales and derivative sales which are not within the scope of revenue from contracts with customers. Fixed income also includes investment banking fees earned for services related to underwriting debt securities and performing portfolio advisory services. FHN's performance obligation for underwriting services is satisfied on the trade date while advisory services is satisfied over time.
Deposit Transactions and Cash Management. Deposit transactions and cash management activities 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. FHN's obligation for transaction-based services is satisfied at the time of the transaction when the service is delivered while FHN's obligation for service based fees is satisfied over the course of each month.
Brokerage, Management Fees and Commissions. Brokerage, management fees and commissions include fees for portfolio management, trade commissions, and annuity and mutual fund sales. Asset-based management fees are charged based on the market value of the client’s assets. The services associated with these revenues, which include investment advice and active management of client assets are generally performed and recognized over a month or quarter. Transactional revenues are based on the size and number of transactions executed at the client’s direction and are generally recognized on the trade date.
Trust Services and Investment Management. Trust services and investment management fees include investment management, personal trust, employee benefits, and custodial trust services. Obligations for trust services are generally satisfied over time but may be satisfied at points in time for certain activities that are transactional in nature.
Bankcard Income. Bankcard income includes credit interchange and network revenues and various card-related fees. Interchange income is recognized concurrently with the delivery of services on a daily basis. Card-related fees such as late fees, currency conversion, and cash advance fees are loan-related and excluded from the scope of ASU 2014-09.

Note 1 – Summary of Significant Accounting Policies (Continued)
Contract Balances. As of December 31, 2019, accounts receivable related to products and services on non-interest income were $8.7 million. For the year ended December 31, 2019, FHN had no material impairment losses on non-interest accounts receivable and there were no material contract assets, contract liabilities or deferred contract costs recorded on the Consolidated Statement of Condition as of December 31, 2019.
Transaction Price Allocated to Remaining Performance Obligations. For the year ended December 31, 2019, revenue recognized from performance obligations related to prior periods was not material. Revenue expected to be recognized in any future year related to remaining performance obligations, excluding revenue pertaining to contracts that have an original expected duration of one year or less and contracts where revenue is recognized as invoiced, is not material.
Refer to Note 20 - Business Segment Information for a reconciliation of disaggregated revenue by major product line and reportable segment.
Debt Investment Securities. Available-for-sale ("AFS") and held-to-maturity (“HTM”) 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 are classified as AFS and are carried at fair value. The unrealized gains and losses on debt securities AFS, including 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 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.
Equity Investment Securities. Equity securities are classified in Other assets.
National banks chartered by the federal government are, and banks organized under state law may apply to be, 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. FRB and FHLB stock are recorded at cost and are subject to impairment reviews. FHN's subsidiary, First Horizon Bank, was a member bank throughout 2019, initially as a national bank and later as a state member bank.
Other equity investments primarily consist of mutual funds which are marked to fair value through earnings. Smaller balances of equity investments without a readily determinable fair value are recorded at cost minus impairment with adjustments through earnings for observable price changes in orderly transactions for the identical or a similar investment of the same issuer.
Securities Purchased Under Agreements to Resell and Securities Sold Under Agreements to Repurchase. FHN purchases short-term securities under agreements to resell which are accounted for as collateralized financings except where FHN does not have an agreement to sell the same or substantially the same securities before maturity at a fixed or determinable price. 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.
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 126

Note 1 – Summary of Significant Accounting Policies (Continued)
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 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 for 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 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 was elected, loan origination fees were 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, premiums and discounts are recognized in interest income upon early repayment of the loans. Cash collections from loans that were fully charged off prior to acquisition are recognized in noninterest income. Loan commitment fees are generally deferred and amortized on a straight-line basis over the commitment period.
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 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.

Note 1 – Summary of Significant Accounting Policies (Continued)
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.
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.
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 128

Note 1 – Summary of Significant Accounting Policies (Continued)
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. Impairments, and any subsequent recoveries, are recorded in noninterest expense. Gains and losses on dispositions are reflected in noninterest income and expense, respectively.
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 years to fifteen years and seven years 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. Properties acquired by foreclosure in compliance with HUD servicing guidelines prior to January 1, 2015, are included in “OREO” and are carried at the estimated amount of the underlying government insurance or guarantee. On December 31, 2019, FHN had $2.2 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
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 129

Note 1 – Summary of Significant Accounting Policies (Continued)
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 are recorded in accumulated other comprehensive income and subsequently reclassified to earnings as the hedged transaction impacts net income. Prior to 2018, ineffectiveness in debt and cash flow hedges was recorded in noninterest expense. Starting in 2018, 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 financial statement line item (e.g., interest expense) 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 (e.g., interest income). 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.
Leases. At inception, all arrangements are evaluated to determine if they contain a lease, which is defined as a contract, or part of a contract, that conveys the right to control the use of identified property, plant, or equipment for a period of time in exchange for consideration. Control is deemed to exist when a lessor has granted and a lessee has received both the right to obtain substantially all of the economic benefits from use of the identified asset and the right to direct the use of the identified asset throughout the period of use.
Lessee. As a lessee, FHN recognizes lease (right-of-use) assets and lease liabilities for all leasing arrangements with lease terms that are greater than one year. The lease asset and lease liability are recognized at the present value of estimated future lease payments, including estimated renewal periods, with the discount rate reflecting a fully-collateralized rate matching the estimated lease term. Renewal options are included in the estimated lease term if they are considered reasonably certain of exercise. Periods covered by termination options are included in the lease term if it is reasonably certain they will not be exercised. Additionally, prepaid or accrued lease payments, lease incentives and initial direct costs related to lease arrangements are recognized within the right-of-use asset. Each lease is classified as a financing or operating lease 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. Substantially all of FHN’s lessee arrangements are classified as operating leases. For leases with a term of 12 months or less, FHN does not to recognize lease assets and lease liabilities and expense is generally recognized on a straight-line basis over the lease term.
Lease assumptions and classification are reassessed upon the occurrence of events that result in changes to the estimated lease term or consideration. Modifications to lease contracts are evaluated to determine 1) if a right to use an additional asset has been obtained, 2) if only the lease term and/or consideration have been revised or 3) if a full or partial termination has occurred. If an additional right-of use-asset has been obtained, the modification is treated as a separate contract and its classification is evaluated as a new lease arrangement. If only the lease term or consideration are changed, the lease liability is revalued with an offset to the lease asset and the lease classification is re-assessed. If a modification results in a full or partial termination of the lease, the lease liability is revalued through earnings along with a proportionate reduction in the value of the related lease asset and subsequent expense recognition is similar to a new lease arrangement.
Lease assets are evaluated for impairment when triggering events occur, such as a change in management intent regarding the continued occupation of the leased space. If a lease asset is impaired, it is written down to the present value of estimated future
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 130

Note 1 – Summary of Significant Accounting Policies (Continued)
cash flows and the prospective expense recognition for that lease follows the accelerated expense recognition methodology applicable to finance leases, even if it remains classified as an operating lease.
Sublease arrangements are accounted for consistent with the lessor accounting described below. Sublease arrangements are evaluated to determine if changes to estimates for the primary lease are warranted or if the sublease terms reflect impairment of the related lease asset.
Lease assets are recognized in Other assets and lease liabilities are recognized in Other liabilities in the Consolidated Statements of Condition. Since substantially all of its leasing arrangements relate to real estate, FHN records lease expense, and any related sublease income, within Occupancy expense in the Consolidated Statements of Income.
Lessor. As a lessor, FHN also evaluates its lease arrangements to determine whether a finance lease or an operating lease exists and utilizes the rate implicit in the lease arrangement as the discount rate to calculate the present value of future cash flows. Depending upon the terms of the individual agreements, finance leases represent either sales-type or direct financing leases, both of which require de-recognition of the asset being leased with offsetting recognition of a lease receivable that is evaluated for impairment similar to loans. Currently, all of FHN’s lessor arrangements are considered operating leases.
Lease income for operating leases is recognized over the life of the lease, generally on a straight line basis. Lease incentives and initial direct costs are capitalized and amortized over the estimated life of the lease. Lease income is not significant for any reporting periods and is classified as a reduction of Occupancy expense in the Consolidated Statements of Income.
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. FHN’s federal consolidated tax returns are currently under audit for 2013 through 2015 and the statutes for those years have been extended through December 31, 2020. Federal tax refund claims for Capital Bank Financial Corporation for 2010 - 2012 are under examination by the IRS. Several of FHN’s state returns are currently under examination.
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 and units, restricted shares and units, and options granted under FHN’s equity compensation plans and deferred compensation arrangements had been issued. FHN utilizes the treasury stock
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 131

Note 1 – Summary of Significant Accounting Policies (Continued)
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. Some performance awards include a total shareholder return modifier (“TSR Modifier”) that operates after determination of the performance criteria, affecting only the quantity of awards issued if the minimum performance threshold is attained. The effect of the TSR Modifier is included in the grant date fair value of the related performance awards using a Monte Carlo valuation technique. The fair value of equity awards with cash payout requirements, as well as awards for which fair value cannot be estimated at grant date, is remeasured each reporting period through vesting date. Performance awards with pre-grant date achievement criteria are expensed over the period from the start of the performance period through the end of the service vesting term. Awards are amortized using the nonsubstantive vesting methodology which requires that expense associated with awards having only service vesting criteria that continue vesting after retirement be recognized over a period ending no later than an employee’s retirement eligibility date.
Repurchase and Foreclosure Provision. The repurchase and foreclosure provision is the charge to earnings necessary to maintain the liability at a level that reflects management’s best estimate of losses associated with the repurchase of loans previously transferred in whole loans sales or securitizations, or make whole requests as of the balance sheet date. See Note 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.Costs related to equity issuances are netted against Capital surplus. Costs related to debt issuances are included in debt issuance costs that are recorded within Term borrowings.
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 generally 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, 2019, FHN adopted the provisions of 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.
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 132

Note 1 – Summary of Significant Accounting Policies (Continued)
Effective January 1, 2019, FHN adopted the provisions of ASU 2018-11, “Leases - Targeted Improvements,” which provides an election for a cumulative effect adjustment to retained earnings upon initial adoption of ASU 2016-02. Alternatively, under the initial guidance of ASU 2016-02, lessees and lessors are required to recognize and measure leases at the beginning of the earliest comparative period presented using a modified retrospective approach. Both adoption alternatives include 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. Upon adoption, FHN utilized the cumulative effect transition alternative provided by ASU 2018-11. FHN utilized the lease classification practical expedients and the short-term lease exemption upon adoption. FHN also has elected to determine the discount rate on leases as of the effective date and elected to use hindsight in determining lease terms as well as impairments of lease assets resulting from lease abandonments upon adoption. The table below summarizes the impact of adopting ASU 2016-02 as of January 1, 2019, for line items in the Consolidated Statements of Condition. Lease assets of approximately $185 million are included in Other Assets. Lease liabilities of approximately $204 million are included in Other Liabilities. The after-tax decrease in Undivided Profits reflects the recognition of deferred gains associated with prior sale-leaseback transactions, revisions to the estimated useful lives of leasehold improvements and adjustments of lease expense to reflect revised lease duration estimates.

Effective January 1, 2019, FHN adopted the provisions of ASU 2018-15, “Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract,” which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). Capitalized implemented costs are required to be expensed over the term of the hosting arrangement which includes the non-cancellable period of the arrangement plus periods covered by (1) an option to extend the arrangement if the customer is reasonably certain to exercise that option, (2) an option to terminate the arrangement if the customer is reasonably certain not to exercise the termination option, and (3) an option to extend (or not to terminate) the arrangement in which exercise of the option is in the control of the vendor. ASU 2018-15 also requires application of the impairment guidance applicable to long-lived assets to the capitalized implementation costs. Amortization expense related to capitalized implementation costs must be presented in the same line item in the statement of income as the fees associated with the hosting element (service) of the arrangement and payments for capitalized implementation costs will be classified in the statement of cash flows in the same manner as payments made for fees associated with the hosting element. Capitalized implementation costs will be presented in the statement of financial position in the same line item that a prepayment for the fees of the associated hosting arrangement would be presented. FHN elected early adoption of ASU 2018-15 using the prospective transition method and the effects of adoption were not significant.
In April 2019, the FASB issued ASU 2019-04, “Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments,” which makes several revisions and clarifications to the accounting for these items. The revisions related to ASU 2016-03 (Topic 326) are discussed below. ASU 2019-04 clarifies several aspects of fair hedge accounting, including the application to partial term fair value hedges. ASU 2019-04 provides an election regarding the timing for amortization of basis adjustments to hedged items in fair value hedges, indicating that amortization may, but is not required to, commence prior to the end of the hedge relationship. ASU 2019-04 also provides additional guidance related to the application of the hypothetical derivative method and first-payments-received method in cash flow hedges. Further, ASU 2019-04 indicates that remeasurement of an equity security without a readily determinable fair value when an orderly transaction is identified for an identical or similar investment of the same issuer represents a non-recurring fair value measurement and the related disclosure requirements apply to the remeasurement event. The hedging updates are effective at the beginning of the first annual reporting period after issuance with early adoption permitted. The financial instruments measurement and disclosure changes are effective for fiscal years and interim periods beginning after December
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 133

Note 1 – Summary of Significant Accounting Policies (Continued)
15, 2019 with early adoption permitted. FHN early adopted these portions of ASU 2019-04 in second quarter 2019 and the effects were not significant based on its existing accounting practices.
Accounting Changes Issued but Not Currently Effective
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. Under CECL the full amount of expected credit losses will be recognized at the time of loan origination. The measurement of current expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. Additionally, current disclosures of credit quality indicators in relation to the amortized cost of financing receivables will be further disaggregated by year of origination. ASU 2016-13 leaves the methodology for measuring credit losses on AFS debt securities largely unchanged, with the maximum credit loss representing the difference between amortized cost and fair value. However, such credit losses will be recognized through an allowance for credit losses, which permits recovery of previously recognized credit losses if circumstances change.
ASU 2016-13 also revises the recognition of credit losses for purchased financial assets with a more-than insignificant amount of credit deterioration since origination (“PCD assets”). For PCD assets, the initial allowance for credit losses is added to the purchase price. Only subsequent changes in the allowance for credit losses are recorded as a credit loss expense for PCD assets. Interest income for PCD assets will be recognized based on the effective interest rate, excluding the discount embedded in the purchase price that is attributable to the acquirer’s assessment of credit losses at acquisition. Currently, credit losses for purchased credit-impaired assets are included in the initial basis of the assets with subsequent declines in credit resulting in expense while subsequent improvements in credit are reflected as an increase in the future yield from the assets. For non-PCD assets, expected credit losses will be recognized through earnings upon acquisition and the entire premium or discount will be accreted to interest income over the remaining life of the loan.
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 increased to offset the initial recognition 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. FHN’s most significant implementation activities included review of loan portfolio segments and classes, identification and evaluation of collateral dependent loans and loans secured by collateral replenishment arrangements, selection of measurement methodologies and related model development, data accumulation and verification, development of loan life estimates, identification of reasonable and supportable forecast periods, selection of timelines and methods for reversion to unadjusted historical information, multiple preliminary analyses including parallel runs against existing loan loss estimation processes, and design and evaluation of internal controls over the new estimation processes. FHN will utilize undiscounted cash flow methods for loans except for troubled debt restructurings, which require use of discounted cash flow methodologies.
Based on implementation efforts, FHN expects to incur a decrease to Undivided profits of approximately $100 million as of January 1, 2020, related to an increase in the allowance for loan losses as well as an increase in the reserve for unfunded commitments. A significant portion of this impact relates to increased reserves within the consumer portfolios, given the longer contractual maturities associated with many of these products as well as reserves related to acquired loans. FHN expects the coverage ratio for total loans to be approximately 100 basis points at adoption but would expect future coverage to be affected by changes in economic forecasts, portfolio composition and loan terms. The total impact from adoption to FHN's regulatory
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 134

Note 1 – Summary of Significant Accounting Policies (Continued)
capital ratio CET1 is anticipated to be a decrease of approximately 7 basis points in 2020. Management is in the final stages of documenting the accounting, reporting and governance processes associated with the adoption of ASU 2016-13.
FHN also assessed several asset classes other than loans that are within the scope of CECL and determined that the adoption effects for the change in measurement of credit risk were minimal for these classes. This includes Fed funds sold which have no history of credit losses due to their short (typically overnight) duration and counterparty risk assessment processes. This also includes securities borrowed and securities purchased under agreements to resell which have collateral maintenance agreements that incorporate master netting provisions resulting in minimal uncollateralized positions as of any date as evidenced by the disclosures provided in Note 23 - Master Netting and Similar Agreements-Repurchase, Reverse Repurchase, and Securities Borrowing Transactions. Additionally, FHN has also evaluated the composition of its AFS securities and determined that the changes in ASU 2016-13 will not have a significant effect on the current portfolio.
ASU 2019-04 provides an election to either not measure or measure separately an allowance for credit losses for accrued interest receivable (“AIR"). Entities electing to not measure an allowance for AIR must write off uncollectible interest in a timely manner. Additionally, an election is provided for the write off of uncollectible interest to be recorded either as a reversal of interest income or a charge against the allowance for credit losses or a combination of both. Disclosures are required depending upon which elections are made.
ASU 2019-04 also clarifies that when loans and securities are transferred between balance sheet categories (e.g., loans from held-for-investment to held-for-sale or securities from held-to-maturity to available-for-sale) the associated allowance for credit losses should be reversed to income and prospective accounting follows the requirements for the new classification. Further, ASU 2019-04 clarifies that recoveries should be incorporated within the estimation of the allowance for credit losses. Expected recoveries should not exceed the aggregate amount of prior write offs and expected future write offs. The inclusion of expected recoveries in the measurement of expected credit losses may result in a negative credit allowance in certain circumstances. Additionally, for collateral dependent financial assets, the allowance for credit losses that is added to the amortized cost basis should not exceed amounts previously written off.
ASU 2019-04 also makes several changes when a discounted cash flow approach is used to measure expected credit losses. ASU 2019-04 removes ASU 2016-03’s prohibition of using projections of future interest rate environments when using a discounted cash flow method to measure expected credit losses on variable-rate financial instruments. If an entity uses projections or expectations of future interest rate environments in estimating expected cash flows, the same assumptions should be used in determining the effective interest rate used to discount those expected cash flows. The effective interest rate should also be adjusted to consider the effects of expected prepayments on the timing of expected future cash flows. ASU 2019-04 provides an election to adjust the effective interest rate used in discounting expected cash flows to isolate credit risk in measuring the allowance for credit losses. Further, the discount rate should not be adjusted for subsequent changes in expected prepayments if a financial asset is restructured in a troubled debt restructuring.
Related to collateral-dependent financial assets, ASU 2019-04 requires inclusion of estimated costs to sell in the measurement of expected credit losses in situations where the entity intends to sell rather than operate the collateral. Additionally, the estimated costs to sell should be undiscounted when the entity intends to sell rather than operate the collateral.
Finally, ASU 2019-04 specifies that contractual renewal or extension options, except those treated as derivatives, should be included in the determination of the contractual term for a financial asset when included in the original or modified contract as of the reporting date if they are not unconditionally cancellable by the entity.
The effective date and transition requirements for these components of ASU 2019-04 are consistent with the requirements for ASU 2016-13 and FHN incorporated these changes and revisions within its implementation efforts. Based on its previous existing practices for the timely write off uncollectible AIR, FHN elected to not measure an allowance for credit losses for AIR and to continue recognition of related write offs as a reversal of interest income.
In May 2019, the FASB issued ASU 2019-05, “Financial Instruments - Credit Losses, Targeted Transition Relief,” which provides an option to irrevocably elect the fair value option for certain financial assets previously measured at amortized cost basis that are in the scope of ASU 2016-13, applied on an instrument-by-instrument basis. The fair value option election does not apply to held-to-maturity debt securities. The effective date and transition requirements for ASU 2019-05 are consistent with the requirements for ASU 2016-13. FHN did not elect to apply the fair value option to any asset classes that are in scope for CECL.
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 135

Note 1 – Summary of Significant Accounting Policies (Continued)
In November 2019, the FASB issued ASU 2019-11, “Codification Improvements to Topic 326, Financial Instruments-Credit Losses” which clarifies that expected recoveries should be included in the amortized cost basis previously written off or expected to be written off in the valuation allowance for PCD assets. ASU 2019-11 also clarifies that recoveries or expected recoveries of the unamortized noncredit discount or premium should not be included in the allowance for credit losses. ASU 2019-11 provides specific transition relief for existing troubled debt restructurings and extends the disclosure relief of ASU 2019-04 for accrued interest receivable balances to additional relevant disclosures involving amortized cost basis. Related to the assessment of credit risk for collateralized assets, ASU 2019-11 indicates that an entity should assess whether it reasonably expects the borrower will be able to continually replenish collateral securing the financial asset to apply the practical expedient of ASU 2016-13 while also requiring an estimation of expected credit losses for any difference between the amount of the amortized cost basis that is greater than the fair value of the collateral securing the financial asset.
The effective date and transition requirements for ASU 2019-11 are consistent with the requirements for ASU 2016-13 and FHN incorporated these changes and revisions within its implementation efforts and the effects are embedded within the adoption effects of ASU 2016-13. Consistent with non-PCD assets, the effect of including recoveries and expected recoveries within the measurement of expected credit losses for PCD assets may result in a negative credit allowance in certain circumstances.

Note 2 – Acquisitions and Divestitures
On November 4, 2019, FHN and IBERIABANK Corporation (“IBKC”) announced that they had entered into an agreement and plan of merger under which IBKC will merge with FHN in a merger-of-equals transaction. IBKC, headquartered in Lafayette, Louisiana, has 319 offices in 12 states, mostly in the southern and southeastern U.S., and has reported $31.7 billion of total assets, $24.0 billion in loans, and $25.2 billion in deposits, at December 31, 2019. IBKC's common stock is listed on The NASDAQ Stock Market, LLC under the symbol IBKC. Under the merger agreement, each share of IBKC common stock will be converted into 4.584 shares of FHN common stock. After closing, FHN expects IBKC common shares will be converted into approximately 44 percent of the then-outstanding shares of FHN common stock. The merger agreement requires FHN to expand its board of directors to seventeen persons; after closing, eight board positions will be held by current IBKC directors, and nine will be held by current FHN directors. FHN expects the transaction to close mid-2020, subject to regulatory approvals, approval by the shareholders of FHN and of IBKC, and other customary conditions. Merger and integration expenses related to the pending merger of equals with IBKC are recorded in FHN’s Corporate segment.
Total merger expenses for the IBKC merger recognized during 2019 were as follows:

|  | Year Ended December 31,
(Dollars in thousands) |  | 2019
Professional fees (a) |  | $ | 8,228 |
Employee compensation, incentives and benefits (b) |  | 3,079 |

Total IBKC merger expense |  | $ | 11,371 |

(a) Primarily comprised of fees for legal, accounting, investment bankers, and merger consultants.
(b) Primarily comprised of fees for severance and retention.
(c) Primarily comprised of fees for travel and entertainment.
On November 8, 2019, FHN announced an agreement for First Horizon Bank to purchase 30 branches from SunTrust Bank in conjunction with SunTrust Banks, Inc.'s merger with BB&T Corporation, which created Truist Financial Corp. As part of the agreement, FHN will assume approximately $2.4 billion of branch deposits for a 3.40 percent deposit premium and purchase approximately $410 million of branch loans. The branches are in communities in North Carolina (20 branches), Virginia (8 branches), and Georgia (2 branches). FHN expects the purchase to close in second quarter 2020, subject to customary closing conditions.
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 92,042,232 shares of FHN common stock and $423.6 million in cash in a transaction valued at $2.2 billion. In second quarter 2018, FHN canceled 2,373,220 common shares which had been issued but set aside for certain shareholders of CBF who have commenced a dissenters' appraisal process resulting in a reduction in equity consideration and an increase in cash consideration of $46.0 million. In October 2019 this matter was resolved and the financial statement effects were not significant. CBF operated 178 branches in North and South Carolina, Tennessee, Florida and Virginia at the time of closing. In relation to the acquisition, FHN acquired approximately $9.8 billion in assets, including approximately $7.3 billion in loans and $1.2 billion in AFS securities, and assumed approximately $8.1 billion of CBF deposits.
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. These fair value measurements are based on third party and internal valuations.

(c) | Amount primarily relates to a net deferred tax asset recorded for the effects of the purchase accounting adjustments and adjustments for acquired tax contingencies.

In relation to the acquisition, FHN recorded goodwill of approximately $1.2 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 obtained through integration of back office functions and 4) proportionately lower net operating costs from a larger company scale. $17.0 million of goodwill was determined to be deductible for tax purposes as a result of tax bases carryover resulting from prior CBF acquisitions. FHN’s operating results for 2018 and 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.
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 138

Table of Contents
Note 2 – Acquisitions and Divestitures (Continued)
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. The valuation of loans held-for-sale reflects contractual or bid prices.
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.
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.

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 adjustment 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 on 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.
All expenses related to the merger and integration with CBF are recorded in FHN's Corporate segment. Integration activities were substantially completed in second quarter 2018.
Total CBF merger and integration expense recognized for the years ended December 31, 2019, 2018, and 2017 are presented in the table below:

In first quarter 2018, FHN divested two branches, including approximately $30 million of deposits and $2 million of loans. The branches, both in Greeneville, Tennessee, were divested in connection with First Horizon's agreement with the U.S. Department of Justice and commitments to the Board of Governors of the Federal Reserve System, which were entered into in connection with a customary review of FHN's merger with CBF.
In second quarter 2018, FHN sold approximately $120 million UPB of its subprime auto loans. These loans, originally acquired as part of the CBF acquisition, did not fit within FHN's risk profile. Based on the sales price, a measurement period adjustment to the acquisition-date fair value of the subprime auto loans was recorded in second quarter 2018. A measurement period

adjustment was made in fourth quarter 2018 for other consumer loans acquired from CBF based on pricing information received from potential buyers.
On April 3, 2017, FHN Financial (formerly FTN Financial or "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, securiti zation, and analysis of Small Business Administration (“SBA”) loans, for appro ximately $131 million in cash. Coastal, which was based in Houston, TX, also traded United States Department of Agriculture (“USDA”) loans and fixed income products and provided municipal underwriting and advisory services to its clients. Coastal’s government-guaranteed loan products, combined with FHN Financial’s existing SBA trading activities, have established an additional major product sector for FHN Financial.

In relation to the acquisition, FHN has recorded $45.0 million in goodwill, representing the excess of acquisition consideration over the estimated fair value of net assets acquired (refer to Note 7 - Intangible Assets for additional information), and all of which is expected to be deductible for tax purposes. The goodwill is the result of adding an experienced workforce, establishing an additional major product sector for FHN Financial, expected synergies, and other factors. FHN's operating results for 2017 include the operating results of the acquired assets and assumed liabilities of Coastal subsequent to the acquisition on April 3, 2017.
In 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. In April 2019, FHN sold a subsidiary acquired as part of the CBF acquisition that did not fit within FHN's risk profile. The sale resulted in the removal of approximately $25 million UPB of subprime consumer loans from Loans held-for-sale on FHN's Consolidated Statements of Condition.

FHN has reviewed debt investment securities that were in unrealized loss positions in accordance with its accounting policy for OTTI and does not consider them other-than-temporarily impaired. For debt securities with unrealized losses, FHN does not intend to sell them and it is more-likely-than-not that FHN will not be required to sell them prior to recovery. The decline in value is primarily attributable to changes in interest rates and not credit losses.
The carrying amount of equity investments without a readily determinable fair value was $25.6 million and $21.3 million at December 31, 2019 and 2018, respectively. The year-to-date 2019 and 2018 gross amounts of upward and downward valuation adjustments were not significant.
Unrealized gains of $7.0 million and unrealized losses of $1.5 million were recognized during 2019 and 2018, respectively, for equity investments with readily determinable fair values.
In 2018 FHN sold its remaining holdings of Visa Class B Shares resulting in a pre-tax gain of $212.9 million recognized within the Corporate segment. See the Other Derivatives section of Note 22 - Derivatives for more information regarding FHN’s Visa shares.

Note 4 – Loans
The following table provides the balance of loans, net of unearned income, by portfolio segment as of December 31, 2019 and 2018:

Total net loans |  | $ | 30,860,804 |  |  | $ | 27,355,108 |

(a) | In third quarter 2019, FHN corrected a previous mis-classification of commercial loans and reclassified approximately $410 million of market investor CRE loans from the C&I portfolio to the CRE portfolio. These loans were identified during an internal review and assessment by management of certain loan populations, a portion of which relate to loans acquired as part of the Capital Bank merger. The reclassification of these loan balances between regional banking portfolios did not have an impact on FHN’s consolidated period-end or average balance sheet and had an immaterial effect on the allowance for loan losses. No adjustments were made to prior periods as the impact of the reclassification, including the effect on the allowance for loan losses was deemed to be immaterial in all periods.

(b) | Balance as of December 31, 2018 includes $16.2 million of restricted real estate loans. 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 (20 percent of total loans), the majority of which is in the consumer real estate segment (19 percent of total loans). Loans to finance and insurance companies total $2.8 billion (14 percent of the C&I portfolio, or 9 percent of the total loans). FHN had loans to mortgage companies totaling $4.4 billion (22 percent of the C&I segment, or 14 percent of total loans) as of December 31, 2019. As a result, 36 percent of the C&I segment is sensitive to impacts on the financial services industry.
Restrictions
On December 31, 2019, $5.2 billion of commercial loans were pledged to secure potential discount window borrowings from the Federal Reserve Bank. As of December 31, 2019 and 2018, FHN pledged all of its first and second lien mortgages,
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 145

Table of Contents
Note 4 – Loans (Continued)
HELOCs, excluding restricted real estate loans, and commercial real estate loans to secure potential borrowings from the FHLB-Cincinnati. Restricted loans secured borrowings associated with consolidated VIEs. See Note 21 - Variable Interest Entities for additional discussion.
Acquisition
Generally, the fair value for 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, $4.7 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.
Purchased Credit-Impaired Loans
The following table presents a rollforward of the accretable yield for the year ended December 31, 2019 and 2018:

|  | Year Ended December 31
(Dollars in thousands) |  | 2019 |  | 2018
Balance, beginning of period |  | $ | 13,375 |  |  | $ | 15,623 |

Other |  | (367 | ) |  | (198 | )
Balance, end of period |  | $ | 9,808 |  |  | $ | 13,375 |

(a) | Represents the removal of accretable difference for the remaining loans in a pool which is now in a recovery state.

(b) | Includes changes in the accretable yield due to both transfers from the nonaccretable difference and the impact of changes in the expected timing of the cash flows.

At December 31, 2019, the ALLL related to PCI loans was $2.0 million compared to $4.0 million at December 31, 2018. Net charge-offs related to PCI loans during 2019 were $5.8 million, compared to $6.7 million in 2018. The loan loss provision expense related to PCI loans during 2019 was $1.3 million, compared to $4.8 million during 2018.
The following table reflects the outstanding principal balance and carrying amounts of the acquired PCI loans as of December 31, 2019 and 2018:

Asset Quality Indicators
FHN employs a dual grade commercial risk grading methodology to assign an estimate for the probability of default (“PD”) and the loss given default (“LGD”) for each commercial loan using factors specific to various industry, portfolio, or product segments that result in a rank ordering of risk and the assignment of grades PD 1 to PD 16. This credit grading system is intended to identify and measure the credit quality of the loan portfolio by analyzing the migration of loans between grading categories. It is also integral to the estimation methodology utilized in determining the allowance for loan losses since an allowance is established for pools of commercial loans based on the credit grade assigned. Each PD grade corresponds to an estimated one-year default probability percentage; a PD 1 has the lowest expected default probability, and probabilities increase as grades progress down the scale. PD 1 through PD 12 are “pass” grades. PD grades 13-16 correspond to the regulatory-defined categories of special mention (13), substandard (14), doubtful (15), and loss (16). Pass loan grades are required to be reassessed annually or earlier whenever there has been a material change in the financial condition of the borrower or risk characteristics of the relationship. All commercial loans over $1 million and certain commercial loans over $500,000 that are graded 13 or worse are reassessed on a quarterly basis. Loan grading discipline is regularly reviewed internally by Credit Assurance Services to determine if the process continues to result in accurate loan grading across the portfolio. FHN may utilize availability of guarantors/sponsors to support lending decisions during the credit underwriting process and when determining the assignment of internal loan grades. LGD grades are assigned based on a scale of 1-12 and represent FHN’s expected recovery based on collateral type in the event a loan defaults. See Note 5 – Allowance for Loan Losses for further discussion on the credit grading system.

(a) | Balances presented net of a $20.2 million valuation allowance. In 3Q18, FHN sold $55.5 million of TRUPS loans with a $5.0 million valuation allowance. Upon sale, a gain of $3.8 million was recognized in the Non-Strategic segment within Fixed Income in the Consolidated Statement of Income. An additional TRUPS loan with a principal balance of $3.0 million and a valuation of $.3 million was paid off in fourth quarter 2018.

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, 2019 and 2018:

|  | December 31, 2019 |  | December 31, 2018

Troubled Debt Restructurings
As part of FHN’s ongoing risk management practices, FHN attempts to work with borrowers when necessary to extend or modify loan terms to better align with their current ability to repay. Extensions and modifications to loans are made in accordance with internal policies and guidelines which conform to regulatory guidance. Each occurrence is unique to the borrower and is evaluated separately.
A modification is classified as a TDR if the borrower is experiencing financial difficulty and it is determined that FHN has granted a concession to the borrower. FHN may determine that a borrower is experiencing financial difficulty if the borrower is currently in default on any of its debt, or if it is probable that a borrower may default in the foreseeable future. Many aspects of a borrower’s financial situation are assessed when determining whether they are experiencing financial difficulty. Concessions could include extension of the maturity date, reductions of the interest rate (which may make the rate lower than current market for a new loan with similar risk), reduction or forgiveness of accrued interest, or principal forgiveness. The assessments of whether a borrower is experiencing (or is likely to experience) financial difficulty, and whether a concession has been granted, are subjective in nature and management’s judgment is required when determining whether a modification is classified as a TDR.
For all classes within the commercial portfolio segment, TDRs are typically modified through forbearance agreements (generally 6 to 12 months). Forbearance agreements could include reduced interest rates, reduced payments, release of guarantor, or entering into short sale agreements. FHN’s proprietary modification programs for consumer loans are generally structured using parameters of U.S. government-sponsored programs such as the former Home Affordable Modification Program (“HAMP”). Within the HELOC and R/E installment loans classes of the consumer portfolio segment, TDRs are typically modified by reducing the interest rate (in increments of 25 basis points to a minimum of 1 percent for up to 5 years) and a possible maturity date extension to reach an affordable housing debt-to-income ratio. After 5 years, the interest rate generally returns to the original interest rate prior to modification; for certain modifications, the modified interest rate increases 2 percent per year until the original interest rate prior to modification is achieved. Permanent mortgage TDRs are typically modified by reducing the interest rate (in increments of 25 basis points to a minimum of 2 percent for up to 5 years) and a possible maturity date extension to reach an affordable housing debt-to-income ratio. After 5 years, the interest rate steps up 1 percent every year until it reaches the Federal Home Loan Mortgage Corporation Weekly Survey Rate cap. Contractual maturities may be extended to 40 years on permanent mortgages and to 30 years for consumer real estate loans. Within the credit card class of the consumer portfolio segment, TDRs are typically modified through either a short-term credit card hardship program or a longer-term credit card workout program. In the credit card hardship program, borrowers may be granted rate and payment reductions for 6 months to 1 year. In the credit card workout program, customers are granted a rate reduction to 0 percent and term extensions for up to 5 years to pay off the remaining balance.
Despite the absence of a loan modification, the discharge of personal liability through bankruptcy proceedings is considered a concession. As a result, FHN classifies all non-reaffirmed residential real estate loans discharged in Chapter 7 bankruptcy as nonaccruing TDRs.
On December 31, 2019 and 2018, FHN had $206.3 million and $228.2 million of portfolio loans classified as TDRs, respectively. For TDRs in the loan portfolio, FHN had loan loss reserves of $19.7 million, or 10 percent as of December 31, 2019, and $27.7 million, or 12 percent as of December 31, 2018. Additionally, $51.1 million and $57.8 million of loans held-for-sale as of December 31, 2019 and 2018, respectively, were classified as TDRs.

Note 5 – Allowance for Loan Losses
As discussed in Note 1 - Summary of Significant Accounting Polices, the ALLL includes the following components: reserves for commercial loans evaluated based on pools of credit graded loans and reserves for pools of smaller-balance homogeneous consumer loans, both determined in accordance with ASC 450-20-50, and to a lesser extent, reserves determined in accordance with ASC 310-10-35 for loans determined by management to be individually impaired and an allowance associated with PCI loans.
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).

a) | In third quarter 2019, FHN corrected a previous mis-classification of commercial loans and reclassified approximately $410 million of market investor CRE loans from the C&I portfolio to the CRE portfolio. These loans were identified during an internal review and assessment by management of certain loan populations, a portion of which relate to loans acquired as part of the Capital Bank merger. The reclassification of these loan balances between regional banking portfolios did not have an impact on FHN’s consolidated period-end or average balance sheet and had an immaterial effect on the allowance for loan losses. No adjustments were made to prior periods as the impact of the reclassification, including the effect on the allowance for loan losses was deemed to be immaterial in all periods.

Gross goodwill, accumulated impairments, and accumulated divestiture related write-offs were determined beginning January 1, 2002, when a change in accounting requirements resulted in goodwill being assessed for impairment rather than being amortized. Gross goodwill of $200.0 million with accumulated impairments and accumulated divestiture-related write-offs of $114.1 million and $85.9 million, respectively, were previously allocated to the non-strategic segment, resulting in $0 net goodwill allocated to the non-strategic segment as of December 31, 2019, 2018 and 2017.

Note 10 – Term Borrowings (Continued)
In conjunction with the acquisition of CBF, FHN acquired junior subordinated debentures with aggregate par values of $212.4 million. 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 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. FHN retired $45.4 million of this debt and the related trust preferred securities in 2018.

Note 11 – 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. For all periods presented, these securities 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, 2019 the Class B Preferred Shares partially qualified as Tier 2 regulatory capital. They are not subject to any sinking fund and are not convertible into any other securities of FTRESC, FHN, or any of its subsidiaries. In the event First Horizon Bank becomes undercapitalized, insolvent, or in danger of becoming undercapitalized, the shares are, however, automatically exchanged at the direction of the Federal banking regulators for preferred stock of First Horizon Bank, having substantially the same terms as the Class B Preferred Shares.
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 Condition and which partially qualifies as Tier 2 capital. Other preferred shares are outstanding but are owned by FHN subsidiaries and are eliminated in consolidation.
In 2005 First Horizon Bank 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 First Horizon Bank while for FHN consolidated they qualify partially as Tier 1 capital and partially as Tier 2 capital. On December 31, 2019 and 2018, $294.8 million of Class A Preferred Stock was recognized as Noncontrolling interest on the Consolidated Statements of Condition.

Note 12 – Regulatory Capital and Restrictions
Regulatory Capital. FHN and First Horizon Bank 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 First Horizon Bank 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, 2019, FHN and First Horizon Bank met all capital adequacy requirements to which they were subject.
The actual capital amounts and ratios of FHN and First Horizon Bank are presented in the table below.

Note 12 – Regulatory Capital and Restrictions (Continued)
Restrictions on cash and due from banks. Under the Federal Reserve Act and Regulation D, First Horizon Bank is required to maintain a certain amount of cash reserves. On December 31, 2019 and 2018, First Horizon Bank's net required reserves were $396.1 million and $371.7 million, respectively, after the consideration of $273.7 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 First Horizon Bank to transfer funds to FHN in the form of cash, dividends, loans, or advances. As of December 31, 2019, First Horizon Bank had undivided profits of $1.2 billion, of which a limited amount was available for distribution to FHN as dividends without prior regulatory approval. Certain regulatory restrictions exist regarding the ability of First Horizon Bank to transfer funds to FHN in the form of cash, dividends, loans, and advances. At any given time, the pertinent portions of those regulatory restrictions allow First Horizon Bank to declare preferred or common dividends without prior regulatory approval in an amount equal to First Horizon Bank's retained net income for the two most recent completed years plus the current year to date. For any period, First Horizon Bank’s ‘retained net income’ generally is equal to First Horizon Bank’s regulatory net income reduced by the preferred and common dividends declared by First Horizon Bank. Applying the dividend restrictions imposed under applicable federal and state rules, First Horizon Bank’s total amount available for dividends was $331.2 million at January 1, 2020. First Horizon Bank declared and paid common dividends to the parent company in the amount of $345.0 million in 2019 and $420.0 million in 2018. In January 2020, First Horizon Bank declared and paid a common dividend to the parent company in the amount of $65.0 million. During 2019 and 2018, First Horizon Bank declared and paid dividends on its preferred stock quarterly. Additionally, First Horizon Bank declared preferred dividends in first quarter 2020 payable in April 2020.
The payment of cash dividends by FHN and First Horizon Bank may also be affected or limited by other factors, such as the requirement to maintain adequate capital above regulatory guidelines. Beginning January 1, 2019, the ability to pay dividends for both FHN and First Horizon Bank is restricted if capital ratios fall below regulatory minimums for Common Equity Tier 1, Tier 1, Total Capital ratios plus a 2.5 percent capital conservation buffer or 50 basis points above the capital ratios required to be considered well-capitalized. Furthermore, the Federal Reserve generally requires 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 laws, First Horizon Bank 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 $426.0 million, on December 31, 2019. 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. On December 31, 2019, the parent company had covered transactions of $.8 million from First Horizon Bank and two of the bank’s financial subsidiaries, FHN Financial Securities Corp. and First Horizon Advisors, Inc., had covered transactions from First Horizon Bank totaling $390.4 million and $34.7 million, respectively. 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 $851.9 million, on December 31, 2019. First Horizon Bank’s total covered transactions with all affiliates including the parent company on December 31, 2019 were $425.9 million.

The Tax Cuts and Jobs Act “Tax Act” was signed into law at the end of 2017. The Tax Act reduced the federal statutory tax rate from 35 percent to 21 percent effective January 1, 2018. FHN recorded approximately $82 million of increase in tax expense related to the effects of the Tax Act during 2017 which was primarily related to an adjustment of DTA balances to the lower federal tax rate. In 2018, FHN recorded a tax benefit of $6.7 million related to the finalization of tax items for the 2017 tax return.
A reconciliation of expected income tax expense/(benefit) at the federal statutory rate of 21 percent for 2019 and 2018, respectively, and 35 percent for 2017 to the total income tax expense follows:

Note 15 – Income Taxes (Continued)
As of December 31, 2019, FHN had net deferred tax asset balances related to federal and state income tax carryforwards of $43.8 million and $1.2 million, respectively, which will expire at various dates as follows:

(Dollars in thousands) |  | Expiration Dates |  | Net Deferred Tax Asset Balance
Losses-federal |  | 2028-2033 |  | $ | 43,774 |
Net operating losses-states |  | 2020-2022 |  | 62 |
Net operating losses-states |  | 2025-2035 |  | 1,124 |

A deferred tax asset (“DTA”) or deferred tax liability (“DTL”) is recognized for the tax consequences of temporary differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. The tax consequence is calculated by applying enacted statutory tax rates, applicable to future years, to these temporary differences. In order to support the recognition of the DTA, FHN’s management must believe that the realization of the DTA is more likely than not. FHN evaluates the likelihood of realization of the DTA based on both positive and negative evidence available at the time, including (as appropriate) scheduled reversals of DTLs, projected future taxable income, tax planning strategies, and recent financial performance. Realization is dependent on generating sufficient taxable income prior to the expiration of the carryforwards attributable to the DTA. In projecting future taxable income, FHN incorporates assumptions including the estimated amount of future state and federal pretax operating income, the reversal of temporary differences, and the implementation of feasible and prudent tax planning strategies. These assumptions require significant judgment about the forecasts of future taxable income and are consistent with the plans and estimates used to manage the underlying business.
As of December 31, 2019, FHN's net DTA was $69.0 million compared to the $127.9 million at December 31, 2018. At December 31, 2019, FHN's gross DTA (net of a valuation allowance) and gross DTL were $250.6 million and $181.6 million, respectively. 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.
Temporary differences which gave rise to deferred tax assets and deferred tax liabilities on December 31, 2019 and 2018 were as follows:

Note 15 – Income Taxes (Continued)
The total unrecognized tax benefits (“UTB”) at December 31, 2019 and 2018, was $24.4 million and $20.2 million, respectively. To the extent such unrecognized tax benefits as of December 31, 2019 are subsequently recognized, $18.4 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 federal and state exposures could decrease by $6.7 million and $.5 million, respectively during 2020 if audits are completed and settled and if the applicable statutes of limitations expire as scheduled.
FHN recognizes interest accrued and penalties related to UTB within income tax expense. FHN had approximately $2.9 million and $1.6 million accrued for the payment of interest as of December 31, 2019 and 2018, respectively. The total amount of interest and penalties recognized in the Consolidated Statements of Income during both 2019 and 2018 was an expense of $1.3 million.

Note 17 – Contingencies and Other Disclosures
CONTINGENCIES
Contingent Liabilities Overview
Contingent liabilities arise in the ordinary course of business. Often they are related to lawsuits, arbitration, mediation, and other forms of litigation. Various litigation matters are threatened or pending against FHN and its subsidiaries. Also, FHN at times receives requests for information, subpoenas, or other inquiries from federal, state, and local regulators, from other government authorities, and from other parties concerning various matters relating to FHN’s current or former 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 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 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 pre-2009 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, 2019, the aggregate amount of liabilities established for all such loss contingency matters was $.7 million. These liabilities are separate from those discussed under the heading “Loan 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, 2019, FHN is unable to estimate any material reasonably possible losses ("RPLs") for contingency matters in future periods in excess of currently established liabilities.
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.

Material Matters
FHN was one of multiple defendants in a consolidated putative class action suit: In re GSE Bonds Antitrust Litigation, No. 1:19-cv-01704-JSR (U.S. District Court S.D.N.Y.). The plaintiffs claim that defendants conspired to fix secondary market prices of government-sponsored enterprise (“GSE”) bonds from 2009 through 2015. During the third quarter, FHN reached a class settlement with the plaintiffs, subject to court approval, without admitting liability. Though still subject to court approval, the settlement was paid before year-end and therefore is no longer reflected in established liabilities.
On February 26, 2020, a former shareholder of Capital Bank Financial Corp. ("CBF") filed a putative class action suit, Searles v. DeMartini et al, No. 2020-0136 (Del. Chancery), against certain former directors, officers, and shareholders of CBF, alleging, among other things, that defendants breached certain fiduciary duties in connection with CBF's merger with FHN in 2017. Plaintiff claims unspecified damages related to the merger consideration and opportunity loss. FHN is unable to estimate an RPL range for this matter due to significant uncertainties regarding: whether a class will be certified and, if so, the composition of the class; the amount of potential damages that might be awarded, if any; of any such damages amount, the amount that FHN would be obliged to indemnify; the availability of applicable insurance; and the outcome of discovery, which has not yet begun.
Exposures from pre-2009 Mortgage Business
FHN is contending with indemnification claims related to "other whole loans sold," which were mortgage loans originated by FHN before 2009 and sold outside of an FHN securitization. These claims generally assert that FHN-originated loans contributed to losses in connection with mortgage loans securitized by the buyer of the loans. The claims generally do not include specific deficiencies for specific loans sold by FHN. Instead, the claims generally assert that FHN is liable for a share of the claimant's loss estimated by assessing the totality of the other whole loans sold by FHN to claimant in relation to the totality of the larger number of loans securitized by claimant. FHN is unable to estimate an RPL range for these matters due to significant uncertainties regarding: the number of, and the facts underlying, the loan originations which claimants assert are indemnifiable; the applicability of FHN’s contractual indemnity covenants to those facts and originations; and, in those cases where an indemnity claim may be supported, 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 also has indemnification claims related to servicing obligations. The most significant is 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, was FHN’s subservicer. Nationstar asserts several categories of indemnity obligations in connection with mortgage loans under the subservicing arrangement and under the purchase transaction. This matter currently is not in 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 pre-2009 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 settlements, and some might eventually result in adverse litigation outcomes, but none are included in the material loss contingency liabilities mentioned above or in the RPL range mentioned above.
Mortgage Loan Repurchase and Foreclosure Liability
FHN’s repurchase and foreclosure liability, primarily related to its pre-2009 mortgage businesses, is comprised of accruals to cover estimated loss content in the active pipeline (consisting of mortgage loan repurchase, make-whole, foreclosure/servicing demands and certain related exposures), estimated future inflows, and 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 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, foreclosure, and certain related exposures and has accrued for losses of $14.5 million and $32.3 million as of December 31,
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 175

Table of Contents
Note 17 - Contingencies and Other Disclosures (Continued)
2019 and December 31, 2018, respectively. 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 could be subject to future changes. Changes to any one of these factors could significantly impact the estimate of FHN’s liability.
OTHER DISCLOSURES
Indemnification Agreements and Guarantees
In the ordinary course of business, FHN enters into indemnification agreements for legal proceedings against its directors and officers and standard representations and warranties for underwriting agreements, merger and acquisition agreements, loan sales, contractual commitments, and various other business transactions or arrangements. The extent of FHN’s obligations under these agreements depends upon the occurrence of future events; therefore, it is not possible to estimate a maximum potential amount of payouts that could be required by such agreements.

Note 18 – 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 made no contributions to the qualified pension plan in 2019 and 2017, and made an insignificant contribution to the qualified pension plan in 2018. Management does not currently anticipate that FHN will make a contribution to the qualified pension plan in 2020.
FHN assumed two additional qualified pension plans in conjunction with the CBF acquisition. Both legacy CBF plans were frozen at the time of acquisition. As of December 31, 2018, the aggregate benefit obligation for the plans was $17.1 million and aggregate plan assets were $16.5 million. Benefit payments, expense and actuarial gains/losses related to these plans were insignificant for the first half of 2019 and 2018. In third quarter 2019, FHN settled these plans through the purchase of annuity contracts, making related contributions of $.5 million. Due to the insignificant financial statement impact, these two plans are not included in the disclosures that follow.
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 $5.2 million for 2019. FHN anticipates making benefit payments under the non-qualified plans of $5.2 million in 2020.
Savings plan. FHN provides all qualifying full-time employees with the opportunity to participate in FHN's tax qualifi ed 401(k) savings plan. The qualified plan allows employees to defer receipt of earned salary, up to tax law limits, on a tax-advantaged basis. Accounts, which are held in trust, may be invested in a wide range of mutual funds and in FHN common stock. Up to tax law limits, FHN provides a 100 percent match for the first 6 percent of salary deferred, with company matching contributions invested according to a participant’s current investment 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 $27.7 million for 2019, $29.3 million for 2018, and $23.0 million for 2017.
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 allocation of its assets to asset classes, which primarily represent fixed income investments. 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 time horizon of thirty years. Given its funded status, the asset allocation strategy for the qualified pension plan utilizes fixed income instruments that closely match the estimated duration of payment obligations. Consequently, FHN selected a 4.80 percent assumption for 2019 for the qualified defined benefit pension plan and a .05 percent assumption for postretirement medical plan assets dedicated to employees who retired prior to January 1, 1993. FHN selected a 6.85 percent assumption for 2019 for postretirement medical plan assets dedicated to employees who retired after January 1, 1993.
The discount rates for the three years ended 2019 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 par outstanding so that each issue was sufficiently

Table of Contents
Note 18 – Pension, Savings, and Other Employee Benefits (Continued)
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.
The actuarial assumptions used in the defined benefit pension plans and other employee benefit plans were as follows:

|  | Benefit Obligations |  | Net Periodic Benefit Cost
2019 |  | 2018 |  | 2017 |  | 2019 |  | 2018 |  | 2017

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.
FHN has one pension plan where participants' benefits are affected by interest crediting rates. The plan's projected benefit obligation as of December 31, 2019, 2018 and 2017 and interest crediting rates for the respective years are:

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.
FHN utilizes 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.
The following tables set forth the plans’ benefit obligations and plan assets for 2019 and 2018:

The qualified pension plan was overfunded as of December 31, 2019 by $27.4 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, 2019 and 2018. The qualified pension plan was overfunded as of December 31, 2018 by $1.9 million. FHN's funded post retirement plan was also in an overfunded status as of December 31, 2019 and 2018.
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, 2019 and 2018 consist of:

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.

Plan assets. FHN’s overall investment goal is to create, over the life of the pension plan and retiree medical plan, an adequate pool of sufficiently liquid assets to support the 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 level of investment return consistent with changes in projected benefit obligations.
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, primarily money market funds and mutual funds. On December 31, 2019 and 2018, 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, 2019 and 2018, by asset category classified using the Fair Value measurement hierarchy is shown in the table below. See Note 24 – Fair Value of Assets and Liabilities for more details about Fair Value measurements.

Note 19 - Stock Options, Restricted Stock, and Dividend Reinvestment Plans
Equity compensation plans
FHN currently has one plan, its shareholder-approved Equity Compensation Plan (“ECP”), which authorizes the grant of new stock-based awards to employees and directors. 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 one outstanding award has performance conditions associated with FHN’s stock price. FHN operates the ECP by establishing award programs, each of which is intended to cover a specific need. Programs are created, changed, or terminated as needs change. On December 31, 2019, there were 6,350,062 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, 2019 there were 4,961,854 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 fifth 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 post-vest holding period of two years. Recent annual performance awards require pro-rated forfeiture for performance falling between a threshold level and a maximum. Performance awards sometimes are used to provide a narrow, targeted incentive to a single person or small group; one such award which includes a market performance condition to FHN’s Chief Executive Officer (“CEO”) is discussed in the next paragraph. Of the annual program awards paid during 2019 or outstanding on December 31, 2019: the 2015 units vested in 2018 and remain in a two year post-vesting holding period; performance conditions related to the 2016 units were met at the 104.2 percent payout level and vested in 2019; the three years performance period of the 2017 units has ended but performance is measured relative to peers and has not yet been determined; and, the three years performance periods for the 2018 and 2019 units have not ended.
Market condition award. In 2016, FHN made a special grant of performance stock units to FHN’s CEO which will vest at the end of a performance period of seven years. The award has no provision for pro-rated payment based on partial performance. The award’s performance goal is based on achievement of a specific level of total shareholder return during the performance period.
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 vest in the year following the year of grant, require a payment deferral of two years, and settle in shares after the deferral period. In 2019 and 2018 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.

Stock and stock unit awards. A summary of restricted and performance stock and unit activity during the year ended December 31, 2019, is presented below:

|  | Shares/ Units (a) |  | Weighted average grant date fair value (per share) (b)
January 1, 2019 |  | 4,089,824 |  |  | $ | 16.27 |
Shares/units granted |  | 1,761,343 |  |  | 14.93 |
Shares/units vested/distributed |  | (1,042,270 | ) |  | 13.99 |
Shares/units cancelled |  | (120,649 | ) |  | 17.43 |
December 31, 2019 |  | 4,688,248 |  |  | $ | 16.25 |

(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 2018 and 2017 was $18.70 and $18.83, respectively.

On December 31, 2019, there was $29.5 million of unrecognized compensation cost related to nonvested restricted stock awards. That cost is expected to be recognized over a weighted-average period of 2.1 years. The total grant date fair value of shares vested during 2019, 2018 and 2017, was $14.6 million, $12.6 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 7 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. 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, 2019, is shown below:

|  | Options Outstanding |  | Weighted Average Exercise Price (per share) |  | Weighted Average Remaining Contractual Term (years) |  | Aggregate Intrinsic Value (thousands)
January 1, 2019 |  | 5,904,687 |  |  | $ | 16.16 |  |  |  |  |
Options granted |  | 530,787 |  |  | 15.43 |  |  |  |  |
Options exercised |  | (895,695 | ) |  | 10.79 |  |  |  |  |
Options expired/cancelled |  | (607,998 | ) |  | 27.94 |  |  |  |  |
December 31, 2019 |  | 4,931,781 |  |  | 15.61 |  |  | 3.08 |  | $ | 13,385 |
Options exercisable |  | 3,347,210 |  |  | 15.76 |  |  | 2.32 |  | 10,060 |
Options expected to vest |  | 1,584,571 |  |  | 15.28 |  |  | 4.68 |  | 3,325 |

The total intrinsic value of options exercised during 2019, 2018 and 2017 was $4.4 million, $3.0 million, and $2.5 million, respectively. On December 31, 2019, there was $1.4 million of unrecognized compensation cost related to nonvested stock options. That cost is expected to be recognized over a weighted-average period of 2.5 years.

Note 19 - Stock Options, Restricted Stock, and Dividend Reinvestment Plans (Continued)
FHN granted or converted 530,787, 394,296 and 1,483,323 stock options with a weighted average fair value of $2.69, $3.89, and $4.69 per option at grant date in 2019, 2018 and 2017, respectively.
FHN used the Black-Scholes Option Pricing Model to estimate the fair value of stock options granted or converted in 2019, 2018, and 2017 with the following assumptions:

|  | 2019 |  | 2018 |  | 2017
Expected dividend yield |  | 3.63% |  | 2.57% |  | 1.82%
Expected weighted-average lives of options granted |  | 6.24 years |  | 6.21 years |  | 6.09 years
Expected weighted-average volatility |  | 24.76% |  | 24.61% |  | 26.90%
Expected volatility range |  | 23.07 - 26.45% |  | 23.95 - 25.26% |  | 24.36 - 29.44%
Risk-free interest rate |  | 2.53% |  | 2.69% |  | 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 $22.7 million, $23.2 million, and $20.6 million for 2019, 2018, and 2017, respectively. The corresponding total income tax benefits recognized were $5.6 million in 2019, $5.7 million in 2018, and $7.9 million in 2017.
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 numbers of shares related to issuance under the ECP and several 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 2020.
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.

Note 20 - 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 primarily in the southeast and other selected markets. Regional banking also provides investments, wealth management, 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, underwriting, 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, acquisition- and integration-related costs, expenses associated with rebranding initiatives, and various charges related to restructuring, repositioning, and efficiency efforts. The non-strategic segment consists of run-off consumer lending activities, pre-2009 mortgage banking elements, and the associated ancillary revenues and expenses related to these businesses. Non-strategic also includes the wind-down trust preferred loan portfolio and exited businesses.
Periodically, FHN adapts its segments to reflect managerial or strategic changes. FHN may also modify its methodology of allocating expenses and equity among segments which could change historical segment results. Business segment revenue, expense, asset, and equity levels reflect those which are specifically identifiable or which are allocated based on an internal allocation method. Because the allocations are based on internally developed assignments and allocations, to an extent they are subjective. Generally, all assignments and allocations have been consistently applied for all periods presented. The following table reflects the amounts of consolidated revenue, expense, tax, and average assets, as well as, depreciation and amortization expense and expenditures for long lived assets for each segment for the years ended December 31:

Note 21 - 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
During much of 2019, FHN held 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 was considered a VIE as the holders of equity at risk did not have the power through voting rights or similar rights to direct the activities that most significantly impacted the trust’s economic performance. The retention of mortgage service rights ("MSR") and a residual interest resulted in FHN potentially absorbing losses or receiving benefits that were significant to the trust. FHN was considered the primary beneficiary, as it was assumed to have the power, as Master Servicer, to most significantly impact the activities of the VIE. Consolidation of the trust resulted in the recognition of the trust proceeds as restricted borrowings since the cash flows on the securitized loans could 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 was reimbursed for these advances only after other parties in the securitization had received all of the cash flows to which they were entitled. Amounts funded from monoline insurance policies were 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 held no recourse to the assets of FHN. This securitization was resolved in fourth quarter 2019.
FHN has established certain rabbi trusts related to deferred compensation plans offered to its employees. FHN contributes employee cash compensation deferrals to the trusts and directs the underlying investments made by the trusts. The assets of these trusts are available to FHN’s creditors only in the event that FHN becomes insolvent. These trusts are considered VIEs as there is no equity at risk in the trusts since FHN provided the equity interest to its employees in exchange for services rendered. FHN is considered the primary beneficiary of the rabbi trusts as it has the power to direct the activities that most significantly impact the economic performance of the rabbi trusts through its ability to direct the underlying investments made by the trusts. Additionally, FHN could potentially receive benefits or absorb losses that are significant to the trusts due to its right to receive any asset values in excess of liability payoffs and its obligation to fund any liabilities to employees that are in excess of a rabbi trust’s assets.

Nonconsolidated Variable Interest Entities
Low Income Housing Partnerships. First Horizon Community Investment Group, Inc. ("FHCIG") (formerly First Tennessee Housing Corporation (“FTHC”)), a wholly-owned subsidiary of First Horizon Bank (formerly First Tennessee Bank National Association ("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 FHCIG, 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. FHCIG 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 FHCIG’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 $1.3 million, $4.1 million, and $1.8 million during 2019, 2018, and 2017, respectively. The following table summarizes the impact to the Provision/(benefit) for income taxes on the Consolidated Statements of Income for the years ended December 31, 2019, 2018 and 2017 for LIHTC investments accounted for under the proportional amortization method.

Note 21 - Variable Interest Entities (Continued)
Other Tax Credit Investments. First Tennessee New Markets Corporation (“FTNMC”), a wholly-owned subsidiary of First Horizon Bank, periodically 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. A NMTC relationship was resolved in 2019 resulting in a $2.7 million decline in the related debt.
FHCIG 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. As of December 31, 2019, there were no remaining investments. 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 FHCIG, 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. FHCIG 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 FHCIG’s initial capital contributions and funding commitments.
Small Issuer Trust Preferred Holdings. First Horizon Bank holds variable interests in trusts which have issued mandatorily redeemable preferred capital securities (“trust preferreds”) for smaller banking and insurance enterprises. First Horizon Bank 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 First Horizon Bank. 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 First Horizon Bank’s holdings, First Horizon Bank 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 First Horizon Bank. However, since First Horizon Bank 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. First Horizon Bank has no contractual requirements to provide financial support to the trusts.
On-Balance Sheet Trust Preferred Securitization. In 2007, First Horizon Bank 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. First Horizon Bank 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 First Horizon Bank did not retain servicing or other decision making rights, First Horizon Bank 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, First Horizon Bank has accounted for the funds received through the securitization as a term borrowing in its Consolidated Statements of Condition. First Horizon Bank 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. Except for recourse due to breaches of representations and warranties made by FHN in connection with the sale of the loans to the trusts, the creditors of the trusts hold no recourse to the assets of FHN. Additionally, FHN has no contractual requirements to provide financial support to the trusts. Based on their restrictive nature, the trusts are considered VIEs as the holders of equity at risk do not have the power through voting rights, or similar rights, to direct the activities that most significantly impact the trusts’ economic performance. However, FHN did not have the ability to participate in significant portions of a securitization trust’s cash flows and FHN was not considered the primary beneficiary of the trust. Therefore, these trusts were not consolidated by FHN.

Table of Contents
Note 21 - Variable Interest Entities (Continued)
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, First Horizon Bank 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 First Horizon Bank 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, First Horizon Bank is exposed to potentially significant benefits and losses of the borrowing entity. First Horizon Bank 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. First Horizon Bank 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, First Horizon Bank loaned funds to a related party of the buyer that were used for the purchase price of the building. First Horizon Bank 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 prior to 2019, it was accounted for using the deposit method which created a net asset or liability for all cash flows between First Horizon Bank and the buyer. Upon adoption of ASU 2016-02 the transaction qualified as a seller-financed sale-leaseback. The buyer-lessor in this transaction meets the definition of a VIE as it does not have sufficient equity at risk since First Horizon Bank 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, First Horizon Bank does not consolidate the leasing entity.
Proprietary Trust Preferred Issuances. In conjunction with the acquisition of CBF, FHN acquired junior subordinated debt underlying multiple issuances of trust preferred debt by institutions previously acquired by CBF. All of the remaining 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.

Note 22 - 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. Daily margin posted or received with
central clearinghouses is considered a legal settlement of the related derivative contracts which results in a net presentation for
each contract in the Consolidated Statements of Condition. Treatment of daily margin as a settlement has no effect
on hedge accounting or gains/losses for the applicable derivative contracts. On December 31, 2019 and 2018, respectively, $136.6 million and $76.0 million of cash receivables and $53.0 million and $34.0 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 to facilitate customer transactions and as a risk management tool. Where contracts have been created for customers, FHN enters into upstream transactions with dealers to offset its risk exposure. Contracts with dealers that require central clearing are novated to a clearing agent who becomes FHN’s counterparty. Derivatives are also used as a risk management tool to hedge FHN’s exposure to changes in interest rates or other defined market risks.
Forward contracts are over-the-counter contracts where two parties agree to purchase and sell a specific quantity of a financial instrument at a specified price, with delivery or settlement at a specified date. Futures contracts are exchange-traded contracts where two parties agree to purchase and sell a specific quantity of a financial instrument at a specified price, with delivery or settlement at a specified date. Interest rate option contracts give the purchaser the right, but not the obligation, to buy or sell a specified quantity of a financial instrument, at a specified price, during a specified period of time. Caps and floors are options that are linked to a notional principal amount and an underlying indexed interest rate. Interest rate swaps involve the exchange of interest payments at specified intervals between two parties without the exchange of any underlying principal. Swaptions are options on interest rate swaps that give the purchaser the right, but not the obligation, to enter into an interest rate swap agreement during a specified period of time.
Trading Activities
FHN’s fixed income segment trades U.S. Treasury, U.S. Agency, government-guaranteed loan, mortgage-backed, corporate and municipal fixed income securities, and other securities for distribution to customers. When these securities settle on a delayed basis, they are considered forward contracts. Fixed income also enters into interest rate contracts, including caps, swaps, and floors, for its customers. In addition, fixed income enters into futures and option contracts to economically hedge interest rate risk associated with a portion of its securities inventory. These transactions are measured at fair value, with changes in fair value recognized currently in fixed income noninterest income. Related assets and liabilities are recorded on the Consolidated Statements of Condition as Derivative assets and Derivative liabilities. The FHN Financial Risk Committee and the Credit Risk Management Committee collaborate to mitigate credit risk related to these transactions. Credit risk is controlled through credit

Interest Rate Risk Management
FHN’s ALCO focuses on managing market risk by controlling and limiting earnings volatility attributable to changes in interest rates. Interest rate risk exists to the extent that interest-earning assets and interest-bearing liabilities have different maturity or repricing characteristics. FHN uses derivatives, primarily swaps, that are designed to moderate the impact on earnings as interest rates change. Interest paid or received for swaps utilized by FHN to hedge the fair value of long term debt is recognized as an adjustment of the interest expense of the liabilities whose risk is being managed. FHN’s interest rate risk management policy is to use derivatives to hedge interest rate risk or market value of assets or liabilities, not to speculate. In addition, FHN has entered into certain interest rate swaps and caps as a part of a product offering to commercial customers that includes customer derivatives paired with upstream offsetting market instruments that, when completed, are designed to mitigate interest rate risk. These contracts do not qualify for hedge accounting and are measured at fair value with gains or losses included in current earnings in Noninterest expense on the Consolidated Statements of Income.
FHN designated a derivative transaction in a hedging strategy to manage interest rate risk on $400.0 million of senior debt issued by First Horizon Bank prior to its maturity December 2019. This qualified 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. First Horizon bank early redeemed the $400.0 million senior debt on November 1, 2019.
FHN has designated a derivative transaction in a hedging strategy to manage interest rate risk on $500.0 million of senior debt which matures in December 2020. This qualifies for hedge accounting under ASC 815-20 using the long-haul method. FHN entered into a pay floating, receive fixed interest rate swap to hedge the interest rate risk of the senior debt.

In first quarter 2016, FHN entered into a pay floating, receive fixed interest rate swap in a hedging strategy to manage its exposure to the variability in cash flows related to the interest payments for the following five years on $250 million principal of debt instruments, which primarily consist of held-to-maturity trust preferred loans that have variable interest payments based on 3-month LIBOR. In first quarter 2017, FHN initiated cash flow hedges of $650 million notional amount that had initial durations between three years 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. Subsequent to 2017, all changes in the fair value of these derivatives are recorded as a component of AOCI. Amounts are reclassified from AOCI to earnings as the hedged cash flows affect earnings. Prior to 2018, FHN measured ineffectiveness using the Hypothetical Derivative Method and AOCI was adjusted to an amount that reflected 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 existed in the hedge relationships, the amounts were 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.

Other Derivatives
In conjunction with the sales of a portion of its Visa Class B shares in 2010 and 2011, 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 is also required to make periodic financing payments to the purchasers until all of Visa's covered litigation matters are resolved. In third quarter 2018, FHN sold the remainder of its Visa Class B shares, entering into a similar derivative arrangement with the counterparty. All of these derivatives extend until the end of Visa’s Covered Litigation matters. In September 2018, Visa reached a preliminary settlement for one class of plaintiffs in its Payment Card Interchange matter, which later received final court approval in December 2019. In accordance with the agreement terms, several individual plaintiffs opted out of the settlement and have the opportunity to separately pursue resolution with Visa. Settlement has not been reached with the second class of plaintiffs in this matter and other covered litigation matters are also pending judicial resolution. Accordingly, the value and timing for completion of Visa’s Covered Litigation matters are uncertain.
The derivative transaction executed in third quarter 2018 includes a contingent accelerated termination clause based on the credit ratings of FHN and First Horizon Bank. FHN has not received or paid collateral related to this contract. As of December 31, 2019 and December 31, 2018, the derivative liabilities associated with the sales of Visa Class B shares were $22.8 million and $31.5 million, respectively. See Note 24 - Fair Value of Assets & Liabilities for discussion of the valuation inputs and processes for these Visa-related derivatives.

Note 22 - Derivatives (Continued)
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, 2019 and December 31, 2018, these loans were valued at $18.4 million and $11.0 million, respectively. The balance sheet amount and the gains/losses associated with these derivatives were not significant.
Master Netting and Similar Agreements
As previously discussed, FHN uses master netting agreements, mutual margining agreements and collateral posting requirements to minimize credit risk on derivative contracts. Master netting and similar agreements are used when counterparties have multiple derivatives contracts that allow for a “right of setoff,” meaning that a counterparty may net offsetting positions and collateral with the same counterparty under the contract to determine a net receivable or payable. The following discussion provides an overview of these arrangements which may vary due to the derivative type and market in which a derivative transaction is executed.
Interest rate derivatives are subject to agreements consistent with standard agreement forms of the International Swap and Derivatives Association (“ISDA”). Currently, all interest rate derivative contracts are entered into as over-the-counter transactions and collateral posting requirements are based on the net asset or liability position with each respective counterparty. For contracts that require central clearing, novation to a counterparty with access to a clearinghouse occurs and margin is posted. Cash margin received (posted) that is considered settlements for the derivative contracts is included in the respective derivative asset (liability) value. Cash margin that is considered collateral received (posted) for interest rate derivatives is recognized as a liability (asset) on FHN’s Consolidated 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 First Horizon Bank is lowered, FHN could be required to post additional collateral with the counterparties. Conversely, if the credit rating of FHN and/or First Horizon Bank 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 First Horizon Bank 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 $63.1 million of assets and $6.4 million of liabilities on December 31, 2019, and $15.0 million of assets and $34.9 million of liabilities on December 31, 2018. As of December 31, 2019 and 2018, FHN had received collateral of $148.5 million and $80.2 million and posted collateral of $18.4 million and $13.3 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 First Horizon Bank'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 $63.1 million of assets and $10.3 million of liabilities on December 31, 2019, and $19.0 million of assets and $33.2 million of liabilities on December 31, 2018. As of December 31, 2019 and 2018, FHN had received collateral of $148.5 million and $84.5 million and posted collateral of $22.7 million and $15.2 million, respectively, in the normal course of business related to these contracts.
FHN’s fixed income segment buys and sells various types of securities for its customers. When these securities settle on a delayed basis, they are considered forward contracts, and are generally not subject to master netting agreements. For futures and

options, FHN transacts through a third party, and the transactions are subject to margin and collateral maintenance requirements. In the event of default, open positions can be offset along with the associated collateral.
For this disclosure, FHN considers the impact of master netting and other similar agreements which allow FHN to settle all contracts with a single counterparty on a net basis and to offset the net derivative asset or liability position with the related securities and cash collateral. The application of the collateral cannot reduce the net derivative asset or liability position below zero, and therefore any excess collateral is not reflected in the following tables.
The following table provides details of derivative assets and collateral received as presented on the Consolidated Statements of Condition as of December 31, 2019 and 2018:

Note 23 - Master Netting and Similar Agreements - Repurchase, Reverse Repurchase, and Securities Borrowing Transactions
For repurchase, reverse repurchase and securities borrowing transactions, FHN and each counterparty have the ability to offset all open positions and related collateral in the event of default. Due to the nature of these transactions, the value of the collateral for each transaction approximates the value of the corresponding receivable or payable. For repurchase agreements through FHN’s fixed income business (Securities purchased under agreements to resell and Securities sold under agreements to repurchase), transactions are collateralized by securities and/or government guaranteed loans which are delivered on the settlement date and are maintained throughout the term of the transaction. For FHN’s repurchase agreements through banking activities (Securities sold under agreements to repurchase), securities are typically pledged at settlement and not released until maturity. For asset positions, the collateral is not included on FHN’s Consolidated Statements of Condition. For liability positions, securities collateral pledged by FHN is generally represented within FHN’s trading or available-for-sale securities portfolios.
For this disclosure, FHN considers the impact of master netting and other similar agreements that allow FHN to settle all contracts with a single counterparty on a net basis and to offset the net asset or liability position with the related securities collateral. The application of the collateral cannot reduce the net asset or liability position below zero, and therefore any excess collateral is not reflected in the tables below.
The following table provides details of Securities purchased under agreements to resell as presented on the Consolidated Statements of Condition and collateral pledged by counterparties as of December 31:

Note 24 - Fair Value of Assets and Liabilities
FHN groups its assets and liabilities measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. This hierarchy requires FHN to maximize the use of observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. Each fair value measurement is placed into the proper level based on the lowest level of significant input. These levels are:

• | Level 1—Valuation is based upon quoted prices for identical instruments traded in active markets.

• | Level 2—Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.

• | Level 3—Valuation is generated from model-based techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models, and similar techniques.

Note 24 - Fair Value of Assets and Liabilities (Continued)
Nonrecurring Fair Value Measurements
From time to time, FHN may be required to measure certain other financial assets at fair value on a nonrecurring basis in accordance with GAAP. These adjustments to fair value usually result from the application of lower of cost or market (“LOCOM”) accounting or write-downs of individual assets. For assets measured at fair value on a nonrecurring basis which were still held on the balance sheet at December 31, 2019, 2018 and 2017, respectively, the following tables provide the level of valuation assumptions used to determine each adjustment, the related carrying value, and the fair value adjustments recorded during the respective periods.

In 2019, FHN recognized $4.6 million of impairments and $.7 million of impairment reversals, respectively, related to dispositions of acquired properties and $1.5 million of impairments for lease assets related to continuing acquisition integration efforts associated with reduction of leased office space and branch optimization. Related to its restructuring, repositioning, and efficiency efforts, FHN recognized $14.0 million of impairments and $1.4 million of impairment reversals, respectively, for tangible long-lived assets and lease assets. Related to the Company's rebranding initiative, FHN recognized $7.1 million of impairments within the Corporate segment for long-lived tangible assets, primarily signage, related to the company's rebranding initiative. These amounts were recognized in the Corporate segment.
In 2018, FHN recognized $3.9 million of impairments of long-lived assets in its Corporate segment primarily related to optimization efforts for its facilities. Also, in 2018, $1.5 million of impairment charges previously recognized in 2017 in the Corporate segment were reversed based on the disposition prices for the applicable locations.
In 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.
Lease asset impairments recognized in 2019 represent the reduction in value of the right-of-use assets associated with leases that are being exited in advance of the contractual lease expiration. Impairments are measured using a discounted cash flow methodology, which is considered a Level 3 valuation.
For all periods, impairments of long-lived tangible assets reflect locations where the associated land and building are either owned or leased. The fair values of owned sites were determined using estimated sales prices from appraisals and broker opinions less estimated costs to sell with adjustments upon final disposition. The fair values of owned assets in leased sites (e.g., leasehold improvements) 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. Impairment adjustments recognized upon disposition of a location are considered Level 2 valuations.

Securities AFS. Increases (decreases) in estimated prepayment rates and bond equivalent yields negatively (positively) affect the value of SBA interest only strips. Management additionally considers whether 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.
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 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. 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.
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. 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.
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 which utilize the platform 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.

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

| Year Ended December 31
(Dollars in thousands) | 2019 |  | 2018 |  | 2017
Changes in fair value included in net income: |  |  |  |  |
Mortgage banking noninterest income |  |  |  |  |
Loans held-for-sale | $ | 1,828 |  |  | $ | 1,239 |  |  | $ | 1,547 |

For the years ended December 31, 2019, 2018 and 2017, the amounts for residential real estate loans held-for-sale included gains of $.4 million, $.2 million, and $.5 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.
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 212

Note 24 - Fair Value of Assets and Liabilities (Continued)
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. Valuations of available-for-sale securities are performed using observable inputs obtained from market transactions in similar securities. Typical inputs include LIBOR and U.S. treasury curves, consensus prepayment estimates, and credit spreads. When available, broker quotes are used to support these valuations.
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.
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 committed bids for specific loans or loan portfolios or 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.
Collateral-Dependent loans. 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

Note 24 - Fair Value of Assets and Liabilities (Continued)
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.
Other assets. For disclosure purposes, other assets consist of tax credit investments, FRB and FHLB Stock, deferred compensation mutual funds and equity investments (including other mutual funds) with readily determinable fair values. 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 mutual funds are recognized at fair value, which is based on quoted prices in active markets.
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.
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.
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.
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, 2019 and December 31, 2018, 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 TRUPS 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.
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.

ITEM 10. DIRECTORS AND EXECUTIVE OFFICERS
OF THE REGISTRANT
-------------------------------
In 2019 there were no material amendments to the procedures, described in our 2020 Proxy Statement under the caption “Shareholder Recommendations of Director Nominees; Shareholder Nominations,” by which security holders may recommend nominees to our Board of Directors.
In January 2019, our Board of Directors amended our bylaws to create a new process, if certain conditions are met, for a shareholder to nominate a person for election to the Board in advance of an annual meeting and to require us to include that nomination in our annual meeting proxy statement. Additional information regarding this process is available in our 2020 Proxy Statement under the captions: “Shareholder Recommendations of Director Nominees; Shareholder Nominations” and “Shareholder Proposal and Nomination Deadlines,” which information is incorporated herein by reference.
Our Board of Directors has adopted a Code of Ethics for Senior Financial Officers that applies to the Chief Executive Officer, Chief Financial Officer, and Chief Accounting Officer and also applies to all professionals
serving in the financial, accounting, or audit areas of FHN and its subsidiaries. A copy of the Code has been filed or incorporated by reference as Exhibit 14 to this report and is posted on our current internet website (at www.firsthorizon.com; click on “Investor Relations,” at the bottom of the web page, then hover over the Investor Relations box at the top of the page, then “Corporate Governance,” and lastly click on “Governance Documents.”) A paper copy of the Code is available without charge upon written request addressed to our Corporate Secretary at our main office, 165 Madison Avenue, Memphis, Tennessee 38103. We intend to satisfy our disclosure obligations under Item 5.05 of Form 8-K related to Code amendments or waivers by posting such information on our internet website, the address for which is listed in this paragraph above.

Plan Category |  | Number of Securities to be Issued upon Exercise of Outstanding Options (1) |  | Weighted Average Exercise Price of Outstanding Options (1) |  | Number of Securities Remaining Available for Future Issuance Under Equity Compensation Plans (excluding securities reflected in Col.

(1) | The numbers of shares covered by stock options and the related option prices have been adjusted proportionately to reflect the estimated economic effects of dividends distributed in common stock effective October 1, 2008 through January 1, 2011. The cumulative compound adjustment factor related to those dividends is 20.038%.

(2) | Consists of the 2000 Directors’ Plans, the ECP, and the CBF Plans. The 2000 Directors’ Plan was approved by shareowners in 2000, and has terminated. The ECP initially was approved by shareowners in 2003, and most recently was re-approved in 2016. The CBF Plans, as to which no new awards will be granted, were approved by shareholders of certain predecessor companies which, directly or indirectly, FHN has acquired.

(3) | Includes 775,188 outstanding options issued under terminated plans approved by shareowners, 45,436 of which directly or indirectly were issued in connection with non-employee director cash deferrals of approximately $0.3 million.

(4) | Consists of the 1997 Plan and the Advisory Board Plans, all of which have terminated. These outstanding options were issued directly or indirectly in connection with employee and advisory board cash deferrals of approximately $5.2 million.

Only the ECP still permits new awards; all other plans have terminated. At December 31, 2019, the total number of shares issuable upon exercise of outstanding options under the ECP was 3,180,664 shares; that number under the terminated plans was 1,751,117 shares. Shares covered by outstanding options are shown in column A. Outstanding
equity awards other than options, consisting of unpaid stock units and restricted stock, are not included in any column. In total, 5,208,515 shares are covered by unpaid awards other than options, all granted under the ECP. Of those, 4,736,558 are covered by unvested awards, and 471,957 are covered by awards that have vested but are
FIRST HORIZON NATIONAL CORP. 2019 FORM 10-K ANNUAL REPORT 222

subject to an unfulfilled mandatory deferral period. In addition, there are 277,200 fully vested deferral stock units outstanding that are the result of previously exercised options under terminated plans for which the receipt of the shares was deferred by the employee.
Column C presents the total number of shares available for new awards under the ECP at December 31, 2019, assuming eventual full exercise or vesting of all shares covered by awards outstanding on that date. Of that total, no more than 4,961,854 shares are available for new awards other than options.
Of the options outstanding at December 31, 2019 (the total under column A), approximately 21% were issued directly or indirectly in connection with employee and director cash deferral elections. We received over many years a total of approximately $5.0 million in employee cash deferrals and $0.5 million in non-employee director and advisory board retainer and meeting fee deferrals related to outstanding deferral options. The opportunity to defer portions of compensation in exchange for options has not been offered to employees, directors, or advisory board members since 2004.
Description of Equity Compensation Plans Not Approved by Shareholders
The 1997 Plan
The 1997 Plan was adopted by the Board of Directors in 1996 and terminated in 2007. The 1997 Plan authorized the grant of nonqualified stock options.
Options were granted under the 1997 Plan prior to its termination pursuant to a management option program, covering a wide range of management-level employees. The last management options granted under the 1997 Plan, with seven-year terms, expired in 2014. However, prior to 2005 certain employees could elect to defer a portion of their annual compensation into stock options under the 1997 Plan. Deferral options still outstanding each had 20-year terms. All options still outstanding under the 1997 Plan were issued directly or indirectly in connection with the deferral program.
All deferral options granted under the 1997 Plan had an
exercise price discounted from grant date fair market value: the aggregate exercise price plus the aggregate compensation foregone equaled the aggregate grant date fair market value. Options could be exercised using shares of FHN stock to pay the option price. When an option was exercised with shares, the option holder sometimes received a new (reload) option grant priced at then-current market (without a discount), covering the remainder of the deferral option's term.
As of December 31, 2019, options covering 961,478 shares of our common stock were outstanding under the 1997 Plan, no shares remained available for future option grants, and options covering 20,913,696 shares had been exercised during the life of the plan. The 1997 Plan was filed most recently as Exhibit 10.2(d) in our Form 10-Q for the quarter ended June 30, 2009.
The Advisory Board Plans
The Advisory Board Plans were adopted by the Board of Directors in 2001 and 1996, and terminated in 2005 and 2002, respectively.
Options granted under the Advisory Board Plans were granted only to regional and advisory board members, or to directors of certain bank affiliates, in any case who were not employees. The options were granted in lieu of the participants receiving retainers or attendance fees for bank board and advisory board meetings. The number of shares subject to grant equaled the amount of fees/retainers earned divided by one half of the fair market value of one share of common stock on the date of the option grant. The exercise price plus the amount of fees foregone equaled the fair market value of the stock on the grant date. The options were vested at the grant date. Those granted on or before January 2, 2004 had terms of twenty years.
As of December 31, 2019, options covering 14,451 shares of our common stock were outstanding under the Advisory Board Plans, no shares remained available for future option grants, and options covering 86,662 shares had been exercised during the life of the Plans. The Advisory Board Plans were included as Exhibits 10.1(f) and 10.1(g) to our Form 10-Q for the quarter ended June 30, 2009.

ITEM 13. CERTAIN RELATIONSHIPS AND
RELATED TRANSACTIONS
--------------------------
The information called for by this Item is incorporated herein by reference to the following sections of our 2020 Proxy Statement, all of which are incorporated into this Item by reference: “Independence & Categorical Standards,” “Approval, Monitoring & Ratification Procedures for Related Party Transactions,” “Transactions with Related Persons,” and “Taylor Arrangements” (within the “Director Compensation Table” section). All other
references to the compensation of, and employment arrangements we had with, R. Eugene Taylor that appear in the “Director Compensation” section of our 2020 Proxy Statement similarly are incorporated into this Item by reference. Our independent directors and nominees are identified in the first paragraph of the “Independence” discussion within the “Independence & Categorical Standards” section of our 2020 Proxy Statement.
------------------------------------
ITEM 14. PRINCIPAL ACCOUNTANT FEES AND SERVICES
------------------------------------
The Audit Committee of the Board of Directors has a policy providing for pre-approval of all audit and non-audit services to be performed by our registered public accounting firm that performs the audit of our consolidated financial statements (our “Auditor”). Services either may be approved in advance by the Audit Committee specifically on a case-by-case basis (“specific pre-approval”) or may be approved in advance (“advance pre-approval”). Advance pre-approval requires the Committee to identify in advance the specific types of service that may be provided and the fee limits applicable to such types of service, which limits may be expressed as a limit by type of service or by category of services. All requests to provide services that have been pre-approved in advance must be submitted to the Chief Accounting Officer prior to the provision of such services for a determination that the service to be provided is of the type and within the fee limit that has been pre-approved. Unless the type of service to be provided by our Auditor has received advance pre-approval under the policy and the fee for such service is within the limit pre-approved, the service will require specific pre-approval by the Committee.
The terms of and fee for the annual audit engagement must receive the specific pre-approval of the Committee. “Audit,” “Audit-related,” “Tax,” and “All Other” services, as those terms are defined in the policy, have the advance pre-approval of the Committee, but only to the extent those services have been specified by the Committee and only in
amounts that do not exceed the fee limits specified by the Committee. Such advance pre-approval is to be for a term of 12 months following the date of pre-approval unless the Committee specifically provides for a different term. Unless the Committee specifically determines otherwise, the aggregate amount of the fees pre-approved for All Other services for the fiscal year must not exceed seventy-five percent (75%) of the aggregate amount of the fees pre-approved for the fiscal year for Audit services, Audit-related services, and those types of Tax services that represent tax compliance or tax return preparation. The policy delegates the authority to pre-approve services to be provided by our Auditor, other than the annual audit engagement and any changes thereto, to the chair of the Committee. The chair may not, however, make a determination that causes the 75% limit described above to be exceeded. Any service pre-approved by the chair will be reported to the Committee at its next regularly scheduled meeting.
Information regarding fees billed to FHN by our Auditor, KPMG LLP, for the two most recent fiscal years is incorporated herein by reference to the section of our 2020 Proxy Statement captioned “Vote Item 3-Ratification of Appointment of Auditors.” No services were approved by the Audit Committee pursuant to Rule 2-01(c)(7)(i)(C) of Regulation S-X.
