Notes to the Consolidated Condensed Financial Statements (Unaudited)

Note 1 – Financial Information

Basis of Accounting. The unaudited interim consolidated condensed financial statements of First Horizon National Corporation (“FHN”), including its subsidiaries, have been prepared in conformity with accounting principles generally accepted in the United States of America and follow general practices within the industries in which it operates. This preparation requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. These estimates and assumptions are based on information available as of the date of the financial statements and could differ from actual results. In the opinion of management, all necessary adjustments have been made for a fair presentation of financial position and results of operations for the periods presented. These adjustments are of a normal recurring nature unless otherwise disclosed in this Quarterly Report on Form 10-Q. The operating results for the interim 2020 period are not necessarily indicative of the results that may be expected going forward. For further information, refer to the audited consolidated financial statements in Item 8 to FHN’s Annual Report on Form 10-K for the year ended December 31, 2019 .

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.

See Note 1– Summary of Significant Accounting Policies in the Notes to Consolidated Financial Statements on Form 10-K for the year ended December 31, 2019, for a discussion of FHN's key revenues.

Contract Balances. As of March 31, 2020 , accounts receivable related to products and services on non-interest income were $ 8.4 million . For the three months ended March 31, 2020 , 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 Condensed Statements of Condition as of March 31, 2020 . Credit risk is assessed on these accounts receivable each reporting period and the amount of estimated uncollectible receivables is not significant.

Transaction Price Allocated to Remaining Performance Obligations. For the three months ended March 31, 2020 , 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 12– Business Segment Information for a reconciliation of disaggregated revenue by major product line and reportable segment.

Debt Investment Securities. Debt securities that may be sold prior to maturity are classified as available-for-sale (“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 Consolidated Condensed Statements of Comprehensive Income. Debt securities which management has the intent and ability to hold to maturity (“HTM”) are reported at amortized cost. Interest-only strips that are classified as securities AFS are valued at elected fair value. See Note 16 - Fair Value of Assets and Liabilities for additional information. Realized gains and losses (i.e., from sales) for debt investment securities are determined by the specific identification method and reported in noninterest income.

In periods subsequent to 2019, the evaluation of credit risk for HTM debt securities mirrors the process described below for loans held-for-investment. AFS debt securities are reviewed for potential credit impairment at the individual security level. The evaluation of credit risk includes consideration of third-party and government guarantees (both explicit and implicit), senior or subordinated status, credit ratings of the issuer, the effects of interest rate changes since purchase and observable market information such as issuer-specific credit spreads. Credit losses for AFS debt securities are generally recognized through establishment of an allowance for credit losses that cannot exceed the amount by which amortized cost exceeds fair value. Charge offs are recorded as reductions of the security’s amortized cost and the credit allowance. Subsequent improvements in estimated credit losses result in reduction of the credit allowance, but not beyond zero. However, if FHN has the intent to sell or if it is more-likely-than-not that it will be compelled to sell a security with an unrecognized loss, the difference between the security's carrying value and fair value is recognized

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 8

Note 1 – Financial Information (Continued)

through earnings and a new amortized cost basis is established for the security (i.e., no allowance for credit losses is recognized).

FHN has elected to exclude accrued interest receivable (“AIR”) from the fair value and amortized cost basis on AFS debt securities when assessing whether these securities have experienced credit impairment. Additionally, FHN has elected to not measure an allowance for credit losses on AIR for AFS debt securities based on its policy to write off uncollectible interest in a timely manner, which generally occurs when delinquency reaches no more than 90 days for all security types. Any such write offs are recognized as a reduction of interest income. AIR for AFS debt securities is included within Other assets in the Consolidated Condensed Statement of Condition.

In periods prior to 2020, both AFS and HTM securities were reviewed quarterly for possible other-than-temporary impairment (“OTTI”). The review included an analysis of the facts and circumstances of each individual investment such as the degree of loss, the length of time the fair value had 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.

Declines in value judged to be other-than-temporary (“OTTI”) based on FHN’s analysis of the facts and circumstances related to an individual investment, including securities that FHN had the intent to sell, were determined by the specific identification method. For HTM debt securities, OTTI recognized was typically credit-related and was reported in noninterest income. For impaired AFS debt securities that FHN did not intend to sell and was not required to sell prior to recovery but for which credit losses existed, the OTTI recognized was allocated between the total impairment related to credit losses which was reported in noninterest income, and the impairment related to all other factors which was excluded from earnings and reported, net of tax, as a component of other comprehensive income within shareholders’ equity and the Consolidated Condensed Statements of Comprehensive Income.

Fed Funds Sold and Purchased. Fed funds sold and purchased represent unsecured overnight funding arrangements between participants in the Federal Reserve system primarily to assist banks in meeting their regulatory cash reserve requirements. Fed Funds sold are evaluated for credit risk each reporting period. Due to the short duration of each transaction and the history of no credit losses, no credit loss has been recognized.

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. 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 Condensed 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.

Securities purchased under agreements to resell and securities borrowing arrangements are evaluated for credit risk each reporting period. As presented in Note 15 - Master Netting and Similar Agreements - Repurchase, Reverse Repurchase, and Securities Borrowing Transactions, these agreements are collateralized by the related securities and collateral maintenance provisions with counterparties, including replenishment and adjustment on a transaction specific basis. This collateral includes both the securities collateral for each transaction as well as offsetting securities sold under agreements to repurchase with the same counterparty. Given the history of no credit losses and collateralized nature of these transactions, no credit loss has been recognized.

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.

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 9

Note 1 – Financial Information (Continued)

FHN has elected to exclude accrued interest receivable (“AIR”) from the amortized cost basis on for its held-for-investment loan portfolio. FHN has also elected to not measure an allowance for credit losses on AIR for loans held-for-investment based on its policy to write off uncollectible interest in a timely manner, which occurs when a loan is placed on nonaccrual status. Such write offs are recognized as a reduction of interest income. AIR for held-for-investment loans is included within Other assets in the Consolidated Condensed Statements of Condition.

Purchased Credit-Deteriorated Loans. Subsequent to 2019, FHN evaluates all acquired loans to determine if they have experienced a more-than-insignificant deterioration in credit quality since origination (“PCD loans”). PCD loans can be identified on either an 1) individual or 2) pooled basis when the loans share similar risk characteristics. FHN evaluates various absolute factors to assist in the identification of PCD loans, including criteria such as, existing PCD status, risk rating of special mention or lower, nonaccrual or impaired status, identification of prior TDRs, and delinquency status. FHN also utilizes relative factors to identify PCD loans such as commercial loan grade migration, expansion of borrower credit spreads, declines in external risk ratings and changes in consumer loan characteristics (e.g., FICO decline or LTV increase). In addition, factors reflective of broad economic considerations are also considered in identifying PCD loans. These include industry, collateral type, and geographic location for the borrower’s operations. Internal factors for origination of new loans that are similar to the acquired loans are also evaluated to assess loans for PCD status, including increases in required yields, necessity of borrowers’ providing additional collateral and/or guarantees and changes in acceptable loan duration. Other indicators may also be used to evaluate loans for PCD status depending on borrower-specific communications and actions, such public statements, initiation of loan modification discussions and obtaining emergency funding from alternate sources.

Upon acquisition, the expected credit losses are allocated to the purchase price of individual PCD loans to determine each individual assets amortized cost basis, typically resulting in a reduction of the discount that is accreted prospectively to interest income. At the acquisition date and prospectively, only the unpaid principal balance is incorporated within the estimation of expected credit losses for PCD loans. Otherwise, the process for estimate of expected credit losses is consistent with that discussed below. As discussed below FHN applies undiscounted cash flow methodologies for the estimation of expected credit losses, which results in the calculated amount of credit losses at acquisition that is added to the amortized cost basis of the related PCD loans to exceed the discounted value of estimated credit losses included in the loan valuation.

Purchased Credit-Impaired Loans. Prior to 2020, ASC 310-30 “Accounting for Certain Loans or Debt Securities Acquired in a Transfer,” established guidance for acquired loans that exhibited deterioration of credit quality between origination and the time of acquisition and for which the timely collection of the interest and principal was not reasonably assured (“PCI loans”). PCI loans were initially recorded at fair value which was estimated by discounting expected cash flows at acquisition date. The expected cash flows included all contractually expected amounts (including interest) and incorporated 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 was based upon common risk characteristics that include similar credit risk or risk ratings, and one or more predominant risk characteristics. Each PCI pool was accounted for as a single unit.

Accretable yield was initially established at acquisition and is the excess of cash flows expected at acquisition over the initial investment in the loan and was recognized in interest income over the remaining life of the loan, or pool of loans. Nonaccretable difference was initially established at acquisition and was the difference between the contractually required payments at acquisition and the cash flows expected to be collected at acquisition. FHN estimated expected cash flows for PCI loans on a quarterly basis. Increases in expected cash flows from the last measurement resulted 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 resulted in an increase in the allowance for loan losses through provision expense.

FHN did not report PCI loans as nonperforming loans due to the accretion of interest income. Additionally, PCI loans that have been pooled and subsequently modified were not reported as troubled debt restructurings since the pool was the unit of measurement.

Subsequent to 2019, PCI loans have transitioned to purchased-credit-deteriorated status and are accounted for as discussed above.

Allowance for Loan Losses. 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. The discussion herein reflects periods before and after implementation of a change in credit loss estimation processes that was effective January 1, 2020.

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 10

Note 1 – Financial Information (Continued)

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.

Subsequent to 2019

The ALLL is maintained at a level that management determines is sufficient to absorb current expected credit losses (“CECL”) in the loan portfolio. Management uses analytical models to estimate expected credit losses in the loan portfolio as of the balance sheet date. The models are carefully reviewed to identify trends that may not be captured in the modeled loss estimates. Management uses qualitative adjustments for those items not reflected in the modeled loss information such as recent changes from the macroeconomic forecasts utilized in model calculations, results of additional stressed modeling scenarios, observed and/or expected changes affecting borrowers in specific industries or geographic areas, exposure to large lending relationships and expected recoveries of prior charge offs.

The ALLL is increased by the provision for loan losses and is decreased by loan charge-offs. The ALLL is determined in accordance with ASC 326-20 "Financial Instruments - Credit Losses.” Credit loss estimation is based on the amortized cost of Loans, net, which includes the following:

Unpaid principal balance for originated assets or acquisition price for purchased assets
Accrued interest (see elections discussed previously)
Accretion or amortization of premium, discount, and net deferred fees or costs
Collection of cash
Charge-offs
Foreign exchange adjustments (none for FHN)
Fair value hedge accounting adjustments (none for FHN)

Premiums, discounts and net deferred origination costs/fees affect the calculated amount of expected credit losses but they are not considered when determining the amount of expected credit losses that are recorded.

Under CECL, loans must be pooled when they share similar risk characteristics with other loans. Loans that do not share similar risk characteristics are evaluated individually. Expected credit loss is estimated for the remaining life of loan(s), which is limited to the remaining contractual term(s), adjusted for prepayment estimates, which are included as separate inputs into modeled loss estimates. Renewals and extensions are not anticipated unless they are included in existing loan documentation

and are not unconditionally cancellable by the lender. However, losses are estimated over the estimated remaining life of reasonably expected TDRs which can extend beyond the current remaining contractual term.

Estimates of expected credit losses incorporate consideration of available information that is relevant to assessing the collectability of future cash flows. This includes internal and external information relating to past events, current conditions and reasonable and supportable forecasts of future conditions. FHN utilizes internal historical loss information as the initial point for estimating expected credit losses. Given the duration of historical information available, FHN considers its internal loss history to fully incorporate the effects of prior credit cycles. The historical loss information may be adjusted in situations where current loan characteristics (e.g., underwriting criteria) differ from those in existence at the time the historical losses occurred. Historical loss information is also adjusted for differences in economic conditions, macroeconomic forecasts and other factors management considers relevant over a period extending beyond the measurement date which is considered reasonable and supportable. This reasonable and supportable period is followed by a reversion period after which loss estimates are based on long-term historical loss averages.

FHN generally measures expected credit losses using undiscounted cash flow methodologies. Credit enhancements (e.g., guarantors) are considered in the estimation of uncollectible cash flows. Estimation of expected credit losses for loan agreements involving collateral maintenance provisions include consideration of the value of the collateral and replenishment requirements, with the maximum loss limited to the difference between the amortized cost of the loan and the fair value of the collateral. Expected credit losses for loans for which foreclosure is probable are measured at the fair value of collateral, less estimated costs to sell when disposition through sale is anticipated. Additionally, certain loans are valued at the fair value of collateral when repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty. Expected credit losses for TDRs are measured in accordance with ASC 310-40, which generally requires a discounted cash flow methodology, whereby the loans are measured based on the present value of expected future payments discounted at the loan’s original effective interest rate.

Expected recoveries of previously charged-off amounts are also included as a qualitative adjustment in the estimation of expected credit losses, which reduces the amount of the allowance recognized. Estimates of recoveries on previously charged-off assets included in the valuation account do not exceed the aggregate of amounts previously written off and expected to be written off.

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 11

Note 1 – Financial Information (Continued)

Since CECL requires estimation of credit for the entire expected life of loans, loss estimates are highly sensitive to changes in macroeconomic forecasts, especially when those forecasts change dramatically in short time periods. Additionally, under CECL credit loss estimates are more likely to increase rapidly in periods of loan growth.

Expected credit losses for unfunded commitments are estimated for periods where the commitment is not unconditionally cancellable by FHN. The measurement of expected credit losses for unfunded commitments mirrors that of loans with the additional estimate of future draw rates (timing and amount).

Prior to 2020

The ALLL was maintained at a level that management determined was sufficient to absorb estimated probable incurred losses in the loan portfolio. The ALLL was increased by the provision for loan losses and loan recoveries and was decreased by loan charge-offs. The ALLL was determined in accordance with ASC 450-20-50 "Contingencies - Accruals for Loss Contingencies" and was 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 were an estimate of probable incurred losses based on management’s evaluation of historical net losses from loans with similar characteristics. Additionally, the ALLL included 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 used analytical models to estimate probable incurred losses in the loan portfolio as of the balance sheet date. The models, which were primarily driven by historical losses, were carefully reviewed to identify trends that may not have been captured in the historical loss factors used in the models. Management used qualitative adjustments for those items not yet captured in the models like then-current events, recent trends in the portfolio, current underwriting guidelines, and local and macroeconomic trends, among other things.

Key components of the estimation process were as follows: (1) commercial loans determined by management to be individually impaired loans were evaluated individually and specific reserves were 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 were segmented based on similar credit risk characteristics and evaluated on a pool basis; (3) reserve rates for the commercial segment were calculated based on historical net charge-offs and were 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 reflected the reserve rates applied against the balance of loans in the commercial segment of the loan portfolio; (5) consumer loans were generally segmented based on loan type; (6) reserve amounts for each consumer portfolio segment were calculated using analytical models based on delinquency trends and net loss experience and were 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 reflected management’s estimate of probable incurred losses in the consumer segment of the loan portfolio.

Impairment related to individually impaired loans was measured in accordance with ASC 310-10. All commercial portfolio segments, commercial TDRs and other individually impaired commercial loans were 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 included consumer TDRs.

Summary of Accounting Changes. 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., HTM loans and debt securities) and 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 prior GAAP as the “incurred loss” methodology for recognizing credit losses delayed recognition until it was probable a loss had 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 are 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 are 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

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 12

Note 1 – Financial Information (Continued)

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 is 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. Previously, credit losses for purchased credit-impaired assets were included in the initial basis of the assets with subsequent declines in credit resulting in expense while subsequent improvements in credit were reflected as an increase in the future yield from the assets. For non-PCD assets, expected credit losses are recognized through earnings upon acquisition and the entire premium or discount accreted to interest income over the remaining life of the loan. Credit allowances for acquired non-PCD assets are established through immediate recognition of credit loss expense (similar to originated loans) and do not consider purchase discounts related to estimated credit losses.

The provisions of ASU 2016-13 were 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 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 are recorded in earnings when received. A prospective transition approach was used for existing PCD assets where, upon adoption, the amortized cost basis was increased to offset the initial recognition of the allowance for credit losses. Thus, an entity was not be required to reassess its purchased financial assets that existed 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 accretes 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 time lines and methods for

reversion to unadjusted historical information, multiple preliminary analysis including parallel runs against existing loan loss estimation processes, and design and evaluation of internal controls over the new estimation processes. FHN utilizes undiscounted cash flow methods for loans except for troubled debt restructurings, which require use of discounted cash flow methodologies.

A significant portion of the adoption impact for ASU 2016-13 relates to increased reserves within the consumer portfolios, given the longer contractual maturities associated with many of these products as well as increased reserves for acquired loans that previously considered purchase discounts. Based on its implementation efforts, FHN recorded the following adoption adjustments effective January 1, 2020.

(Dollars in thousands)	January 1, 2020
Loans, net of unearned income (a)	$ 2,980
Allowance for loan losses	( 106,394	)
Other assets (deferred taxes)	31,330
Total assets	$ ( 72,084	)
Other liabilities (unfunded commitments)	$ 23,973
Undivided profits	( 96,057	)
Total liabilities and equity	$ ( 72,084	)

(a) The effect on loans represents the increase in amortized cost for recognition of the allowance for credit losses on PCD loans.

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 15 - Master Netting and Similar Agreements-Repurchase, Reverse Repurchase, and Securities Borrowing Transactions. Additionally, FHN also evaluated the composition of its AFS securities and determined that the changes in ASU 2016-13 did not have an effect on the current portfolio.

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 provides an election to either 1) not measure or 2) 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

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 13

Note 1 – Financial Information (Continued)

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 HTM 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.

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 1 – Financial Information (Continued)

On March 22, 2020, The Board of Governors of the Federal Reserve System, the Federal Deposit Insurance Corporation, the National Credit Union Administration, the Office of the Comptroller of the Currency, and the Consumer Financial Protection Bureau issued guidance (the “Interagency Guidance”) that interprets, but does not suspend, ASC 310-40 related to the identification of troubled debt restructurings (“TDRs”). Also on that day, the FASB issued a statement indicating that the Interagency Guidance had been developed in consultation with the staff of the FASB who concurred in the approach.

The Interagency Guidance indicates that a lender can conclude that a borrower is not experiencing financial difficulty if either 1) short-term (e.g., six months) modifications are made in response to the economic effects of the Coronavirus disease 2019 (“COVID-19”) pandemic, such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are insignificant related to loans in which the borrower is less than 30 days past due on its contractual payments at the time a modification program is implemented, or 2) the modification or deferral program is mandated by the federal government or a state government. Accordingly, any loan modification made in response to COVID-19 pandemic that meets either of these practical expedients would not be considered a TDR because the borrower is not experiencing financial difficulty. Consistent with this perspective, financial institutions are generally not expected to designate loans with deferrals granted due to COVID-19 as past due or nonaccrual because of a deferral.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was signed into law. The CARES Act provides relief from certain requirements under U.S. GAAP. Section 4013 of the CARES Act provides entities optional temporary relief from the accounting and disclosure requirements for troubled debt restructurings (TDRs) under ASC 310-40 in certain situations. Section 4013 of the CARES Act permits the suspension of ASC 310-40 for loan modifications that are made by financial institutions in response to the COVID-19 pandemic if 1) the borrower was not more than 30 days past due as of December 31, 2019, and 2) the modifications are related to arrangements that defer or delay the payment of principal or interest, or change the interest rate on the loan. The CARES provisions apply to loan modifications relating to COVID-19 that are made between March 1, 2020 and the earlier of December 31, 2020 or 60 days after the national emergency related to COVID-19 ends.

On April 3, 2020, the Chief Accountant of the SEC issued a statement indicating that the staff would not object to the conclusion that elective application of the provisions of CARES Act are in accordance with GAAP for the periods that such elections are available.

On April 7, 2020, revised Interagency Guidance was issued to reflect the interaction of the CARES Act provisions and the Interagency Guidance, clarifying that the CARES Act guidance can be applied for regulatory purposes. Loan modifications outside the scope of the CARES Act and organizations that elect to not apply the CARES Act guidance should continue to apply ASC 310-40 as interpreted by the Interagency Guidance.

FHN has evaluated the provisions of the CARES Act and the Interagency Guidance related to loan modification programs instituted as a result of the COVID-19 pandemic. FHN’s programs involve the deferral of principal and interest payments, fee waivers and extensions for shorter terms (i.e., 6 months or less) or in response to government modification requirements which are consistent with the terms of the Interagency Guidance. Depending upon the duration and severity of the economic effects of the COVID-19 pandemic, additional loan modification programs may be implemented in the future which will be separately evaluated under the CARES Act and the Interagency Guidance.

Accounting Changes Issued but Not Currently Effective

In March 2020, the FASB issued ASU 2020-04, “Facilitation of the Effects of Reference Rate Reform on Financial Reporting” which provides several optional expedients and exceptions to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The provisions of ASU 2020-04 primarily affect 1) contract modifications (e.g., loans, leases, debt, and derivatives) made in anticipation that a reference rate (e.g., LIBOR) will be discontinued and 2) the application of hedge accounting for existing relationships affected by those modifications. The provisions of ASU 2020-04 are effective upon release and apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by ASU 2020-04 do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. FHN has been identifying contracts affected by reference rate reform and developing modification plans for those contracts. FHN anticipates that it will utilize the optional expedients and exceptions provided by ASU 2020-04 in situations where they mitigate potential accounting outcomes that do not faithfully represent management’s intent or risk management activities which is consistent with the purpose of the standard.

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 $ 32.2 billion of total assets, $ 24.5 billion in loans, and $ 25.5 billion in deposits, at March 31, 2020. 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 second quarter 2020, subject to regulatory approvals and other customary conditions. Merger and integration expenses related to the pending merger of equals with IBKC are recorded in FHN’s Corporate segment.

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 third quarter 2020, subject to customary closing conditions.

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 merger in 2017 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 Condensed Statements of Condition.

Note 3 – Investment Securities (Continued)

For periods subsequent to 2019, FHN has evaluated all AFS debt securities that were in unrealized loss positions in accordance with its accounting policy for recognition of credit losses. No AFS debt securities were determined to have credit losses because the primary cause of the decline in value was attributable to changes in interest rates. Total AIR not included in the fair value or amortized cost basis of AFS debt securities was $ 12.3 million as of March 31, 2020 . Consistent with its review of the related securities, there were no credit-related write downs of AIR for AFS debt securities during the reporting period. Additionally, for AFS 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. Therefore, no write downs of these investments to fair value occurred during the reporting period.

For periods prior to 2020, FHN reviewed debt investment securities that were in unrealized loss positions in accordance with its accounting policy for OTTI and did not consider them other-than-temporarily impaired.

For debt securities with unrealized losses, FHN did not intend to sell them and it is more-likely-than-not that FHN would not be required to sell them prior to recovery. The decline in value was primarily attributable to changes in interest rates and not credit losses.

The carrying amount of equity investments without a readily determinable fair value was $ 25.9 million and $ 25.6 million at March 31, 2020 and December 31, 2019 , respectively. The year-to-date 2020 and 2019 gross amounts of upward and downward valuation adjustments were not significant.

Unrealized losses of $ 5.7 million and unrealized gains of $ 3.4 million were recognized in the three months ended March 31, 2020 and 2019 , respectively, for equity investments with readily determinable fair values.

(a) In first quarter 2020, the Permanent Mortgage portfolio was combined into Consumer Real Estate portfolio, all prior periods were revised for comparability.

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 ("LMC"), the trust preferred loans (“TRUPS”) (i.e. long-term unsecured loans to bank and insurance-related businesses) portfolio and purchased credit-impaired (“PCI”) loans (for periods prior to 2020). 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 (for periods prior to 2020). Consumer loan portfolio segments include consumer real estate, and the credit card and other portfolio. Consumer classes include home equity lines of credit (“HELOCs”), real estate (“R/E”) installment and PCI loans (for periods prior to 2020) within the consumer real estate segment and credit card and other.

Credit Risk Characteristics Inherent in the Loan Portfolio

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 transaction, 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. FHN’s credit risk function 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 identified early enough to correct potential deficiencies, prevent further credit deterioration, and mitigate credit losses.

Commercial Loans

The C&I portfolio is comprised of loans used for general business purposes. Typical products including working capital lines of credit, term loan financing of owner-occupied real estate and fixed assets, and trade credit enhancement through letters of credit. FHN utilizes deal teams comprised of relationship managers (RMs), portfolio managers (PMs), credit analysts and other specialists to identify, mitigate, document, and manage ongoing risk. Their function includes enhanced analytical support during loan origination and servicing, monitoring the financial condition of the borrower, and tracking compliance with loan agreements. 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.

To the extent a guarantor/sponsor is used to support a commercial lending decision, FHN analyzes capability to pay, factoring in, among other things, liquidity and direct/indirect cash flows. 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.

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 21

Table of Contents

Note 4 – Loans (Continued)

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. Approximately 90 percent of the loans to mortgage companies are collateralized with government guaranteed loans. The loans are of short duration with maturities less than one year.

TRUPS loans are long-term unsecured loans to bank and insurance-related businesses. 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 regraded at least quarterly as part of FHN’s commercial loan review process.

Commercial Real Estate loans include financings for commercial construction and nonconstruction loans. 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. 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. Active residential CRE lending is primarily focused in certain core markets with nearly all new originations made 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. The credit administration and ongoing monitoring of these portfolios consists of multiple internal control processes including stressing a borrower’s or project’s financial capacity utilizing numerous attributes such as interest rates, vacancy, and discount rates. Key information captured from the various portfolios is aggregated and utilized to assist with the assessment and adequacy of the ALLL and to steer portfolio management strategies.

Consumer Loans

The consumer real estate portfolio is primarily comprised of home equity lines and installment loans within FHN’s regional banking segment and jumbo mortgages and one-time-close (“OTC”) completed construction loans in FHN’s non-strategic segment that were originated through pre-2009 mortgage businesses. The corporate segment also includes loans that were previously included in off-balance sheet proprietary securitization trusts that 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. Generally performance of this portfolio is affected by life events that affect borrowers’ finances, the level of unemployment, and home prices. 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 performance issues with the first lien are discovered.

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 bureaus score since origination, scored 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.

The credit card and other portfolio is primarily comprised of automobile loans, credit card receivables, and other consumer-related credits.

As discussed in Note 1 - Summary of Significant Accounting Policies, the ALLL estimation process was revised on January 1, 2020 to reflect the adoption of ASU 2016-13. All information contained in the following disclosures reflects the application of requirements from the adoption of ASU 2016-13 for periods after 2019. Information for periods prior to 2020 has been retained with the content consistent with prior disclosures.

Concentrations

FHN has a concentration of residential real estate loans ( 19 percent of total loans). Loans to finance and insurance companies total $ 2.8 billion ( 13 percent of the C&I portfolio, or 8 percent of the total loans). FHN had loans to mortgage companies totaling $ 5.7 billion ( 26 percent of the C&I segment, or 17 percent of total loans) as of March 31, 2020 . As a result, 39 percent of the C&I segment is sensitive to impacts on the financial services industry.

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. PD grades assigned through FHN’s risk rating process are used as a loan level input to inform probability of default forecasts under certain macroeconomic scenarios. Each PD grade corresponds to an estimated one-year default probability percentage; a PD 1 has the lowest expected default

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 22

Table of Contents

Note 4 – Loans (Continued)

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.

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 amortized cost basis by year of origination and refreshed FICO scores for consumer real estate as of March 31, 2020 . Within consumer real estate, classes include home equity line of credit ("HELOC") and real estate installment. HELOCs are loans which during their draw period are classified as revolving loans. Once the draw period ends and the loan enters its repayment period, the loan converts to a term loan and is classified as revolving loans converted to term loans. All loans classified in the following table as revolving loans or revolving loans converted to term loans are HELOCs. Real estate installment loans are originated as a fixed term loan and are classified below in their vintage year from prior to 2016 to 2020. All loans in the following table classified in a vintage year are real estate installment loans.

Nonaccrual and Past Due Loans

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. Past due loans are loans contractually past due as to interest or principal payments, but which have not yet been put on nonaccrual status.

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

Table of Contents

Note 4 – Loans (Continued)

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. Prior to 2020, Consumer real estate mortgage TDRs (previously classified as permanent mortgage) were 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 stepped up 1 percent every year until it reached the Federal Home Loan Mortgage Corporation Weekly Survey Rate cap. Contractual maturities may be extended to 40 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 March 31, 2020 and December 31, 2019 , FHN had $ 194.7 million and $ 206.3 million of portfolio loans classified as TDRs, respectively. For TDRs in the loan portfolio, FHN had loan loss reserves of $ 13.9 million , or 7 percent as of March 31, 2020 , and $ 19.7 million , or 10 percent as of December 31, 2019 . Additionally, $ 50.5 million and $ 51.1 million of loans held-for-sale as of March 31, 2020 and December 31, 2019 , respectively, were classified as TDRs.

Note 5 – Allowance for Loan Losses

Periods after 2019

The ALLL has been determined in accordance with ASC 326-20, which requires a recognition of current expected credit losses on the amortized cost basis of loans. During the first quarter of 2020, expected credit loss estimates were adversely affected across all portfolio segments due to the sudden, steep decline in macroeconomic forecasts due to the actual and projected effects of the COVID-19 pandemic. To a lesser extent, loan growth also resulted in a higher ALLL as those increased balances received a full life-of-loan allowance based on current macroeconomic projections.

For all portfolio segments, FHN has selected a 4-year reasonable and supportable forecast period which reflects a 3-year period during which macroeconomic variables are used to estimate expected credit losses. This is followed by a 1-year, time-weighted reversion to historical loss factors with weights assigned to macroeconomic variables diminishing, and weights assigned to historical loss averages increasing, pro rata as months lapse during the 1-year period. Thereafter, FHN immediately reverts to historical loss averages over the remaining estimated life of loans.

In developing credit loss estimates for its loan portfolio, FHN evaluated multiple macroeconomic forecasts provided by Moody’s. FHN selected Moody’s baseline forecast as the primary source for its macroeconomic inputs which are inclusive of the following assumptions related to the economic effects of the COVID-19 pandemic:

• Passage and implementation of the CARES Act

• Federal Reserve stimulus including open-ended quantitative easing and announced programs

• Assumes passage of a fourth stimulus package in in fourth quarter 2020

• Recession starts in the first 6 months of 2020

• Unemployment peaks at 9 percent in second quarter 2020

• The economy experiences a partial bounce back in third quarter 2020, which is followed by slow growth

• GDP growth accelerates later in 2021

• Return to full employment by 2023

FHN also utilized more stressed economic scenarios in evaluating certain components of its loan portfolio (industries) that are most exposed to the effects of the COVID-19 pandemic, including Franchise Finance, Energy and Hospitality within the C&I segment and CRE-Hospitality within the Commercial Real Estate segment. This analysis was utilized in developing qualitative adjustments to increase the recorded ALLL attributable to these components beyond the modeled results. Management also made qualitative adjustments to reflect estimated recoveries based on a review of prior charge off and recovery levels, for default risk associated with large balances with individual borrowers, for estimated loss amounts not reflected in historical factors due to specific portfolio risk and for instances where limited data for acquired loans is considered to affect modeled results.

Typically commercial loans in C&I and CRE have shorter expected lives, based on the contractual term of loan agreements, prepayment estimates and a limited amount of renewal or extension options that are not unconditionally cancellable by FHN. Estimated weighted average lives are normally under 3 years . TRUPs loans are an exception due to longer contractual lives, beneficial borrower terms and balloon payoff structure. Consumer HELOC and installment loans tend to have significantly longer lives based on their contractual terms which is reduced somewhat by estimated prepayments with estimated weighted average lives normally 5 years or less. Credit card loans have shorter estimated lives approximating 1 year based on customer payment trends and because the revolving lines are unconditionally cancellable by FHN.

As of March 31, 2020, FHN had General C&I loans with amortized cost of approximately $ 32 million that was based on the value of underlying collateral. At a minimum, the estimated value of the collateral for each loan equals the current book value. The collateral for these loans generally consists of business assets including land, buildings, equipment and financial assets. During the three months ended March 31, 2020, FHN recognized charge-offs of approximately $ 6 million on these loans related to reductions in estimated collateral values.

Consumer HELOC and installment loans with amortized cost based on the value of underlying real estate collateral were approximately $ 10 million and $ 23 million , respectively, as of March 31, 2020. At a minimum, the estimated value of the collateral for each loan equals the current book value. Charge offs during the three months

ended March 31, 2020 were not significant for either portfolio segment.

Unfunded Commitments

The measurement of expected credit losses for unfunded commitments mirrors that of loans with the additional estimate of future draw rates (timing and amount). Consistent with the ALLL, the decline in macroeconomic forecasts during March resulted in higher credit expense for unfunded commitments. However, this effect of higher loss forecasts was offset somewhat because many borrowers drew on available lines prior to the end of the quarter which resulted in higher loan balances (and ALLL). Total credit loss expense for unfunded commitments was $ 9.2 million for the three months ended March 31, 2020.

Periods prior to 2020

The ALLL included 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 were established using historical net loss factors by grade level, loan product, and business segment. The ALLL for smaller-balance homogeneous consumer loans was determined based on pools of similar loan types that have similar credit risk characteristics. ASC 450-20-50 reserves for the consumer portfolio were determined using segmented roll-rate models that incorporated various factors including historical delinquency trends, experienced loss frequencies, and experienced loss severities. Generally, reserves for consumer loans reflected inherent losses in the portfolio that were 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 were subject to qualitative adjustments by management to reflect current events, trends, and conditions (including economic considerations and trends), which were 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, were examples of additional factors considered by management in determining the ALLL. Additionally, management considered the inherent uncertainty of quantitative models that were driven by historical loss data. Management evaluated the periods of historical losses that were the basis for the loss rates used in the quantitative models and selected historical loss periods that were believed to be the most reflective of losses inherent in the loan portfolio as of the balance sheet date. Management also periodically reviewed an analysis of the loss emergence period which was the amount of time required for a loss to be confirmed (initial charge-off) after a loss event had occurred. FHN performed extensive studies related to the historical loss periods used in the model and the loss emergence period and model assumptions were adjusted accordingly.

Impairment related to individually impaired loans was measured in accordance with ASC 310-10. For all commercial portfolio segments, commercial TDRs and other individually impaired commercial loans were 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 included consumer TDRs. Generally, the allowance for TDRs in all consumer portfolio segments was 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 were adjusted to reflect changes in the interest rate index to which the rates are tied. The discounted cash flows were then compared to the outstanding principal balance in order to determine required reserves. Residential real estate loans discharged through bankruptcy were considered collateral-dependent and were charged down to net realizable value (collateral value less estimated costs to sell).

Amortization expense was $ 5.3 million and $ 6.2 million for the three months ended March 31, 2020 and 2019 , respectively. As of March 31, 2020 the estimated aggregated amortization expense is expected to be:

2025	12,580

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 March 31, 2020 and December 31, 2019 . The regional banking and fixed income segments do not have any accumulated impairments or divestiture related write-offs.

Note 10 – 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 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 March 31, 2020 , the aggregate amount of liabilities established for all such loss contingency matters was $ .6 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 March 31, 2020 , FHN is unable to estimate any material reasonably possible loss ("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 of 2019, FHN reached a class settlement with the plaintiffs, subject to court approval, without

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 40

Table of Contents

Note 10 – Contingencies and Other Disclosures (Continued)

admitting liability. Though still subject to court approval, the settlement has been paid and therefore is not reflected in established liabilities.

In the first quarter of 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 is contending with 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 $ 13.5 million and $ 14.5 million as of March 31, 2020 and December 31, 2019 , respectively. Accrued liabilities for FHN’s estimate of these obligations are reflected in Other liabilities on the Consolidated Condensed Statements of Condition. Charges/expense reversals to increase/decrease the liability are included within Repurchase and foreclosure provision/(provision credit) on the Consolidated Condensed Statements of Income. The 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.

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 42

Note 11 – 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. Management does not currently anticipate that FHN will make a contribution to the qualified pension plan for the remainder of 2020.

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.

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.

Service cost is included in Employee compensation, incentives, and benefits in the Consolidated Condensed Statements of Income. All other components of net periodic benefit cost are included in All other expense.

The components of net periodic benefit cost for the three months ended March 31 are as follows:

(Dollars in thousands)	Pension Benefits — 2020		2019		Other Benefits — 2020		2019

Note 12 – Business Segment Information

FHN has four business segments: regional banking, fixed income, corporate, and non-strategic. The regional banking segment offers financial products and services, including traditional lending and deposit taking, to consumer and commercial customers in 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. 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 for each segment for the three months ended March 31 :

Note 13 – Variable Interest Entities

ASC 810 defines a VIE as a legal entity where (a) the equity investors, as a group, lack sufficient equity at risk for the entity to finance its activities without additional subordinated financial support, (b) the equity investors, as a group, lack either, (1) the power through voting rights, or similar rights, to direct the activities of an entity that most significantly impact the entity’s economic performance, (2) the obligation to absorb the expected losses of the entity, or (3) the right to receive the expected residual returns of the entity, or (c) the entity is structured with non-substantive voting rights. A variable interest is a contractual ownership or other interest that fluctuates with changes in the fair value of the VIE’s net assets exclusive of variable interests. Under ASC 810, as amended, a primary beneficiary is required to consolidate a VIE when it has a variable interest in a VIE that provides it with a controlling financial interest. For such purposes, the determination of whether a controlling financial interest exists is based on whether a single party has both the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant.

Consolidated Variable Interest Entities

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

The following table summarizes the carrying value of assets and liabilities associated with rabbi trusts used for deferred compensation plans which are consolidated by FHN as of March 31, 2020 and December 31, 2019 :

Nonconsolidated Variable Interest Entities

Low Income Housing Partnerships. First Horizon Community Investment Group, Inc. ("FHCIG"), a wholly-owned subsidiary of First Horizon Bank, 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 $ .2 million and $ .5 million for the three months ended March 31, 2020 and 2019 , respectively.

The following table summarizes the impact to the Provision/(benefit) for income taxes on the Consolidated Condensed Statements of Income for the three months ended March 31, 2020 , and 2019 for LIHTC investments accounted for under the proportional amortization method.

( Dollars in thousands )	Three Months Ended March 31 — 2020		2019

Amortization of qualifying LIHTC investments	$ 5,561		$ 3,998
Low income housing tax credits	( 4,598	)	( 3,629	)
Other tax benefits related to qualifying LIHTC investments	( 2,555	)	( 1,610	)

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.

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 March 31, 2020 and December 31, 2019, there were no investments funded through loans from community development enterprises. 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

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 48

Table of Contents

Note 13 – Variable Interest Entities (Continued)

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 Condensed 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.

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

Note 13 – Variable Interest Entities (Continued)

considered “at risk”. Consequently, none of the trusts are consolidated by FHN.

Note 14 – 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 Condensed 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 March 31, 2020 and December 31, 2019 , respectively, FHN had $ 214.4 million and $ 136.6 million of cash receivables and $ 160.7 million and $ 53.0 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 Condensed 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 approvals, risk control limits, and ongoing monitoring procedures. Total trading revenues were $ 78.4 million and $ 44.5 million for the three months ended

Interest Rate Risk Management

FHN’s ALCO focuses on managing market risk by controlling and limiting earnings volatility attributable to changes in interest rates. Interest rate risk exists to the extent that interest-earning assets and interest-bearing liabilities have different maturity or repricing characteristics. FHN uses derivatives, primarily swaps, that are designed to moderate the impact on earnings as interest rates change. Interest paid or received for swaps utilized by FHN to hedge the fair value of long term debt is recognized as an adjustment of the interest expense of the liabilities whose risk is being managed. FHN’s interest rate risk management policy is to use derivatives to hedge interest rate risk or market value of assets or liabilities, not to speculate. In addition, FHN has entered into certain interest rate swaps and caps as a part of a product offering to commercial customers that includes customer derivatives paired with upstream offsetting market instruments that, when completed, are designed to mitigate interest rate risk.

These contracts do not qualify for hedge accounting and are measured at fair value with gains or losses included in

current earnings in Noninterest expense on the Consolidated Condensed Statements of Income.

FHN 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 in 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. $ 200 million of these swaps expired in first quarter 2020. These qualify for hedge accounting as cash flow hedges under ASC 815-20. 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. 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 March 31, 2020 and December 31, 2019 , the derivative liabilities associated with the sales of Visa Class B shares were $ 20.4 million and $ 22.8 million , respectively. See Note 17 - Fair Value of Assets & Liabilities for discussion of the valuation inputs and processes for these Visa-related derivatives.

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 March 31, 2020

and December 31, 2019 , these loans were valued at $ 16.2 million and $ 18.4 million , respectively. The balance sheet amount and the gains/losses associated with these derivatives were not significant.

Related to its loan participation/syndication activities, FHN enters into risk participation agreements, under which it assumes exposure for, or receives indemnification for, borrowers’ performance on underlying interest rate derivative contracts. FHN’s counterparties in these contracts are other lending institutions involved in the loan participation/syndication arrangements for which the underlying interest rate derivative contract is intended to hedge interest rate risk for the borrower. FHN will make (other institution is the lead bank) or receive (FHN is the lead bank) payments for risk participations if the borrower defaults on its obligation to perform under the terms of its interest rate derivative agreement with the lead bank in the participation. As of March 31, 2020 the notional values of FHN’s risk participations were $ 120.8 million of derivative assets and $ 226.7 million of derivative liabilities. The notional value for risk participation/syndication agreements is consistent with the percentage of participation in the lending arrangement. FHN’s maximum exposure or benefit in the risk participation agreements is contingent on the fair value of the underlying interest rate derivative contracts for which the borrower is in a liability position at the time of default. FHN monitors the credit risk associated with the borrowers to which the risk participations relate through the same credit risk assessment process utilized for establishing credit loss estimates for its loan portfolio. These credit risk estimates are included in the determination of fair value for the risk participations. As of March 31, 2020 , FHN had recognized $ 280 thousand of derivative assets and $ 780 thousand of derivative liabilities associated with risk participation agreements.

Note 14 – Derivatives (Continued)

Master Netting and Similar Agreements

As previously discussed, FHN uses master netting agreements, mutual margining agreements and collateral posting requirements to minimize credit risk on derivative contracts. Master netting and similar agreements are used when counterparties have multiple derivatives contracts that allow for a “right of setoff,” meaning that a counterparty may net offsetting positions and collateral with the same counterparty under the contract to determine a net receivable or payable. The following discussion provides an overview of these arrangements which may vary due to the derivative type and market in which a derivative transaction is executed.

Interest rate derivatives are subject to agreements consistent with standard agreement forms of the International Swap and Derivatives Association (“ISDA”). Currently, all interest rate derivative contracts are entered into as over-the-counter transactions and collateral posting requirements are based on the net asset or liability position with each respective counterparty. For contracts that require central clearing, novation to a counterparty with access to a clearinghouse occurs and margin is posted. Cash margin received (posted) that is considered settlements for the derivative contracts is included in the respective derivative asset (liability) value. Cash margin that is considered collateral received (posted) for interest rate derivatives is recognized as a liability (asset) on FHN’s Consolidated Condensed Statements of Condition.

Interest rate derivatives with customers that are smaller financial institutions typically require posting of collateral by the counterparty to FHN. This collateral is subject to a threshold with daily adjustments based upon changes in the level or fair value of the derivative position. Positions and related collateral can be netted in the event of default. Collateral pledged by a counterparty is typically cash or securities. The securities pledged as collateral are not recognized within FHN’s Consolidated Condensed Statements of Condition. Interest rate derivatives associated with lending arrangements share the collateral with the related loan(s). The derivative and loan positions may be netted in the event of default. For disclosure purposes, the entire collateral amount is allocated to the loan.

Interest rate derivatives with larger financial institutions entered into prior to required central clearing typically contain provisions whereby the collateral posting thresholds under the agreements adjust based on the credit ratings of both counterparties. If the credit rating of FHN and/or 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 $ 232.5 million of assets and $ 4.4 million of liabilities on March 31, 2020 , and $ 63.1 million of assets and $ 6.4 million of liabilities on December 31, 2019 . As of March 31, 2020 and December 31, 2019 , FHN had received collateral of $ 291.3 million and $ 148.5 million and posted collateral of $ 41.4 million and $ 18.4 million , respectively, in the normal course of business related to these agreements.

Certain agreements entered into prior to required central clearing also contain accelerated termination provisions, inclusive of the right of offset, if a counterparty’s credit rating falls below a specified level. If a counterparty’s debt rating (including FHN’s and 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 $ 232.3 million of assets and $ 24.2 million of liabilities on March 31, 2020 , and $ 63.1 million of assets and $ 10.3 million of liabilities on December 31, 2019 . As of March 31, 2020 and December 31, 2019 , FHN had received collateral of $ 291.4 million and $ 148.5 million and posted collateral of $ 62.5 million and $ 22.7 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.

Note 15 – Master Netting and Similar Agreements—Repurchase, Reverse Repurchase, and Securities Borrowing Transactions

For repurchase, reverse repurchase and securities borrowing transactions, FHN and each counterparty have the ability to offset all open positions and related collateral in the event of default. Due to the nature of these transactions, the value of the collateral for each transaction approximates the value of the corresponding receivable or payable. For repurchase agreements through FHN’s fixed income business (Securities purchased under agreements to resell and Securities sold under agreements to repurchase), transactions are collateralized by securities and/or government guaranteed loans which are delivered on the settlement date and are maintained throughout the term of the transaction. For FHN’s repurchase agreements through banking activities (Securities sold under agreements to repurchase), securities are typically pledged at settlement

and not released until maturity. For asset positions, the collateral is not included on FHN’s Consolidated Condensed Statements of Condition. For liability positions, securities collateral pledged by FHN is generally represented within FHN’s trading or available-for-sale securities portfolios.

For this disclosure, FHN considers the impact of master netting and other similar agreements that allow FHN to settle all contracts with a single counterparty on a net basis and to offset the net asset or liability position with the related securities collateral. The application of the collateral cannot reduce the net asset or liability position below zero, and therefore any excess collateral is not reflected in the tables below.

Note 16 – Fair Value of Assets & Liabilities

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

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

• Level 2—Valuation is based upon quoted prices for similar instruments in active markets, quoted

prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.

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

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 Consolidated Condensed Statements of Condition at March 31, 2020 , and December 31, 2019 , respectively, the following tables provide the level of valuation assumptions used to determine each adjustment and the related carrying value.

(Dollars in thousands)	Carrying value at March 31, 2020 — Level 1	Level 2	Level 3	Total

OREO (b)	—	—	15,660	15,660
Other assets (c)	—	—	10,608	10,608

(a) Represents carrying value of loans for which adjustments are required to be based on the appraised value of the collateral less estimated costs to sell. Write-downs on these loans are recognized as part of provision for loan losses.

(b) Represents the fair value and related losses of foreclosed properties that were measured subsequent to their initial classification as OREO. Balance excludes OREO related to government insured mortgages.

For assets measured on a nonrecurring basis which were still held on the Consolidated Condensed Statements of Condition at period end, the following table provides information about the fair value adjustments recorded during the three months ended March 31, 2020 and 2019 :

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.

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.

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.

Nonaccrual loans	3,532	6,646	( 3,114	)
Loans 90 days or more past due and still accruing	163	268	( 105	)

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:

(Dollars in thousands)	Three Months Ended March 31 — 2020	2019
Changes in fair value included in net income:
Mortgage banking noninterest income
Loans held-for-sale	$ 329	$ 495

For the three months ended March 31, 2019, the amount for residential real estate loans held-for-sale included a gain of $ .3 million in pretax earnings that is attributable to changes in instrument-specific credit risk. For the three months ended March 31, 2020 this amount was not material. The portion of the fair value adjustments related to credit risk was determined based on estimated default rates and estimated loss severities. Interest income on residential real estate loans held-for-sale measured at fair value is calculated based on the note rate of the loan and is recorded in the interest income section of the Consolidated Condensed Statements of Income as interest on loans held-for-sale.

FHN has elected to account for retained interest-only strips from guaranteed SBA loans recorded in available-for-sale securities at fair value through earnings. Since these securities are subject to the risk that prepayments may result in FHN not recovering all or a portion of its recorded investment, the fair value election results in a more timely recognition of the effects of estimated prepayments

through earnings rather than being recognized through other comprehensive income with periodic review for

other-than-temporary impairment. Gains or losses are recognized through fixed income revenues and are presented in the recurring measurements table.

Determination of Fair Value

In accordance with ASC 820-10-35, fair values are based on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The following describes the assumptions and methodologies used to estimate the fair value of financial instruments recorded at fair value in the Consolidated Condensed Statements of Condition and for estimating the fair value of financial instruments for which fair value is disclosed under ASC 825-10-50.

Short-term financial assets. Federal funds sold, securities purchased under agreements to resell, and interest bearing deposits with other financial institutions and the Federal Reserve are carried at historical cost. The carrying amount is a reasonable estimate of fair value because of the relatively short time between the origination of the instrument and its expected realization.

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 69

Table of Contents

Note 16 – Fair Value of Assets & 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 master netting agreements as well as collateral posting requirements. For derivative contracts with daily cash margin requirements that are considered settlements, the

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 70

Table of Contents

Note 16 – Fair Value of Assets & Liabilities (Continued)

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.

The fair value of risk participations is determined in reference to the fair value of the related derivative contract between the borrower and the lead bank in the participation structure, which is determined consistent with the valuation process discussed above. This value is adjusted for the pro rata portion of the reference derivative’s notional value and an assessment of credit risk for the referenced borrower.

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 Condensed 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 March 31, 2020 and December 31, 2019 , 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.

Note 17 – Restructuring, Repositioning, and Efficiency

Beginning in 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. Restructuring, repositioning, and efficiency charges related to these corporate-driven actions were not significant in first quarter 2020 and were $ 12.2 million in first quarter 2019 and are included in the Corporate segment. Significant expenses resulted from the following actions:

• Severance and other employee costs primarily related to efficiency initiatives within corporate and bank services functions which are classified as Employee compensation, incentives and benefits within noninterest expense.

• Expense largely related to the identification of efficiency opportunities within the organization which is reflected in Professional fees.

Settlement of the obligations arising from current initiatives will be funded from operating cash flows.

Total expense recognized for the three months ended March 31, 2020 and 2019 is presented in the table below:

Dollars in thousands	Three Months Ended March 31 — 2020		2019

General Information

First Horizon National Corporation (“FHN”) began as a community bank chartered in 1864. FHN's sole class of common stock, $.625 par value, is listed and trades on the New York Stock Exchange LLC under the symbol FHN.

FHN is the parent company of First Horizon Bank. First Horizon Bank's principal divisions and subsidiaries operate under the brands of First Horizon Bank, First Horizon Advisors, and FHN Financial. FHN offers regional banking, wealth management and capital market services through the First Horizon family of companies. First Horizon Bank and First Horizon Advisors provide consumer and commercial banking and wealth management services. FHN Financial, which operates partly through a division of First Horizon Bank and partly through subsidiaries, is an industry leader in fixed income sales, trading, and strategies for institutional clients in the U.S. and abroad. First Horizon Bank has over 270 banking offices in seven southeastern U.S. states, and FHN Financial has 29 offices in 18 states across the U.S.

Segments

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. Additionally, the regional banking segment includes correspondent banking which provides credit, depository, and other banking related services to other financial institutions nationally.

• Fixed income segment consists of fixed income securities sales, trading, underwriting, and strategies for institutional clients in the U.S. and abroad, as well as loan sales, portfolio advisory services, and derivative sales.

• Corporate segment consists of unallocated corporate expenses, expense on subordinated debt issuances, bank-owned life insurance, unallocated interest income associated with excess equity, net impact of raising incremental capital, revenue and expense associated with deferred compensation plans, funds management, tax credit investment activities, derivative valuation adjustments related to prior sales of Visa Class B shares, gain/(loss) on extinguishment of debt, acquisition- and integration-related costs, expenses associated with

rebranding initiatives, and various charges related to restructuring, repositioning, and efficiency efforts.

• 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.

Significant Pending Transactions

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 $32.2 billion of total assets, $24.5 billion in loans, and $25.5 billion in deposits, at March 31, 2020. 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 second quarter, subject to regulatory approvals 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 branches), and Georgia (2 branches). FHN expects the purchase to close in third quarter 2020, subject to customary closing conditions.

In second quarter 2019, FHN sold a subsidiary acquired as part of the Capital Bank Financial Corporation ("CBF") merger (in 2017) , 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 Condensed Statements of Condition.

In relation to all acquisitions, FHN's operating results include the operating results of the acquired assets and

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 78

assumed liabilities subsequent to the acquisition date. Refer to Note 2 – Acquisitions and Divestitures in this report and in Item 7 to FHN’s Annual Report on Form 10-K for the year ended December 31, 2019 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 unaudited Consolidated Condensed Financial Statements and Notes in this report. Additional information including the 2019 financial statements, notes, and MD&A is provided in Item 7 and 8 to FHN’s Annual Report on Form 10-K for the year ended December 31, 2019.

ADOPTION OF ACCOUNTING UPDATES

Effective January 1, 2020 FHN adopted ASU 2016-13, "Measurement of Credit Losses on Financial Instruments," (CECL); which resulted in a $106.4 million increase to the allowance for loan losses ("ALLL") and a $24.0 million increase to the reserve for unfunded commitments, resulting in a $96.1 million decrease of retained earnings (net of taxes). See Note 1 – Financial Information 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.

The non-GAAP measure presented in this filing is return on average tangible common equity (“ROTCE”). Refer to table 23 for a reconciliation of the non-GAAP to GAAP measure and presentation of the most comparable GAAP item.

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: general economic and financial market conditions, including expectations of and actual timing and amount of interest rate movements including the slope of the yield curve, competition, customer and investor responses to these conditions, ability to execute business plans, geopolitical developments, recent and future legislative and regulatory developments, natural disasters, the potential impacts on FHN’s businesses of the coronavirus COVID-19 pandemic, including negative impacts from quarantines, market declines and volatility, and changes in customer behavior related to COVID-19, 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 Quarterly Report 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 and exhibits to this Quarterly Report on Form 10-Q for the period ended March 31, 2020 , and in documents incorporated into this Quarterly Report.

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 80

Financial Summary

As previously mentioned, effective January 1, 2020, FHN adopted ASU 2016-13, (CECL). Application of CECL methodology creates larger immediate impacts on credit loss estimates in unanticipated rapid declines in economic projections when compared to the prior incurred loss estimation methodology. The sudden, steep decline in the economic forecast associated with the Coronavirus Disease 2019 (“COVID-19”) pandemic late in first quarter 2020 resulted in a significant increase in loan loss provision expense and the reserve for unfunded commitments, negatively impacting FHN’s operating results in first quarter 2020.

In first quarter 2020, FHN reported net income available to common shareholders of $12.1 million, or $.04 per diluted share, compared to net income available to common of $99.0 million, or $.31 per diluted share in first quarter 2019. The decline in results in first quarter 2020 relative to the prior year was driven by a significant increase in loan loss provision expense and an increase in the reserve for unfunded commitments, somewhat offset by higher revenue.

Total revenue increased 10 percent to $477.6 million in first quarter 2020 from $435.6 million in first quarter 2019. NII increased to $302.8 million in first quarter 2020 from $294.5 million in first quarter 2019 primarily due to strong loan and deposit growth, favorable deposit costs, and the maturity of $400 million of senior debt in fourth quarter 2019. Lower loan yields compared to first quarter 2019 negatively impacted NII in first quarter 2020, offsetting a portion of the overall increase in NII. Noninterest income increased 24 percent, or $33.7 million, in first quarter 2020 driven by higher fixed income revenue, somewhat offset by a decrease in deferred compensation income relative to first quarter 2019.

Noninterest expense increased 5 percent to $311.9 million in first quarter 2020 from $296.1 million in first quarter 2019. The expense increase in first quarter 2020, was due in large part to an increase in credit expense on unfunded

commitments associated with economic uncertainty attributable to the COVID-19 pandemic, as well as higher personnel-related expenses, somewhat offset by lower restructuring and rebranding related expenses.

Asset quality trends in first quarter 2020 were relatively consistent with trends in first quarter 2019. The NPL ratio and 30+ delinquencies improved from .65 percent and .23 percent, respectively in first quarter 2019 to .57 percent and .19 percent, respectively in first quarter 2020. Net charge offs increased from .07 percent in first quarter 2019 to .10 percent in first quarter 2020 primarily driven by two credits.

Return on average common equity (“ROCE”) and ROTCE were 1.05 percent and 1.59 percent, respectively, in first quarter 2020 compared to 9.09 percent and 14.17 percent, respectively, in first quarter 2019. Return on average assets (“ROA”) declined to .15 percent in first quarter 2020 from 1.03 percent in first quarter 2019. Key financial ratios were negatively impacted in first quarter 2020 by the large increase in loan loss provision expense. Common Equity Tier 1, Tier 1, Total Capital, and Leverage ratios were 8.54 percent, 9.52 percent, 10.78 percent, and 9.00 percent, respectively, in first quarter 2020 down from 9.62 percent, 10.65 percent, 11.78 percent, and 9.02 percent, respectively, in first quarter 2019 driven by an increase in risk-weighted assets due to higher loan balances and an increase in fixed income market risk assets. Average assets increased to $43.6 billion in first quarter 2020 from $40.9 billion in first quarter 2019. Average loans and average deposits increased to $30.5 billion and $32.9 billion, respectively, in first quarter 2020, up 12 percent and 1 percent from first quarter 2019. Period-end Shareholders’ equity increased to $5.1 billion in first quarter 2020 from $4.8 billion in first quarter 2019. Average Shareholders’ equity increased to $5.0 billion in first quarter 2020 from $4.8 billion in first quarter 2019.

Business Line Review

Regional Banking

Pre-tax income within the regional banking segment was $25.6 million in first quarter 2020, down from $147.0 million in first quarter 2019. The decrease in pre-tax income was primarily driven by an increase in loan loss provision expense, and higher credit expense on unfunded commitments somewhat offset by increase in revenue.

Total revenue increased 6 percent to $382.0 million in first quarter 2020 from $359.1 million in first quarter 2019, driven by increases in NII and noninterest income. The

increase in NII was primarily due to strong loan and deposit growth and favorable deposit costs, which more than offset lower loan yields compared to first quarter 2019. Noninterest income increased 12 percent or $8.8 million to $81.9 million in first quarter 2020 from $73.0 million in the prior year. The increase in noninterest income was primarily driven by an increase in fees from derivative sales, higher brokerage, management fees and commissions, and an increase in other service charges revenue, partially offset by lower fees from deposit transactions and cash management activities relative to first quarter 2019.

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 81

Provision expense increased to $145.4 million in first quarter 2020 from $13.4 million in first quarter 2019, primarily driven by the application of CECL methodology and a sudden, steep decline in the economic forecast attributable to the COVID-19 pandemic.

Noninterest expense was $211.0 million in first quarter 2020, up from $198.6 million in first quarter 2019. The increase in expense was primarily driven by a $8.8 million increase in the credit expense on unfunded commitments largely associated with the application of CECL methodology with a sudden, steep decline in economic forecast attributable to the COVID-19 pandemic. An increase in FDIC premium expense due to balance sheet growth and expected loss severity ratios as well as $1.0 million of additional credit risk adjustments related to Regional Banking interest rate derivatives and swap participations also contributed to the overall increase in expenses in first quarter 2020 compared to the prior year.

Fixed Income

Pre-tax income in the fixed income segment more than doubled to $25.6 million in first quarter 2020 from $10.6 million in first quarter 2019. The increase in pre-tax income in first quarter 2020 was driven by higher revenue, somewhat offset by an increase in expenses.

Noninterest income increased 78 percent, or $41.9 million to $95.7 million in first quarter 2020 from $53.8 million in first quarter 2019. Average daily revenue (“ADR”) increased to $1.3 million in first quarter 2019 from $729 thousand in first quarter 2019, due to elevated levels of commissionable revenues, partially offset by elevated levels of trading losses driven by extreme market volatility as compared to first quarter 2019. Other product revenue was $17.4 million in first quarter 2020, up from $9.3 million in the prior year, primarily driven by increases in fees from derivative sales. NII was $10.9 million in first quarter 2020, up from $7.3 million in first quarter 2019, primarily due to higher spreads on inventory positions in addition to higher inventory balances compared to prior year.

Noninterest expense was $81.1 million in first quarter 2020 compared to $50.5 million in first quarter 2019, primarily driven by higher variable compensation due to increased commissionable revenues.

Corporate

The pre-tax loss for the corporate segment was $32.5 million in first quarter 2020 compared to $36.3 million in first quarter 2019.

Net interest expense was $13.4 million and $7.9 million in first quarter 2020 and 2019, respectively. Net interest expense was negatively impacted by lower average balances of excess cash at the Federal reserve (“Fed”) and AFS securities, somewhat offset by the maturity of $400 million of senior debt in fourth quarter 2019. Noninterest income/(loss)(including securities gain/losses) in first quarter 2020 was negative $3.7 million compared to $13.4 million in first quarter 2019, primarily due to a $15.0 million decrease in deferred compensation income driven by negative equity market valuations relative to the prior year.

Noninterest expense decreased 63 percent or $26.3 million from $41.8 million in first quarter 2019 to $15.5 million in first quarter 2020. The decrease in expense for first quarter 2020 was primarily driven by decreases in deferred compensation expense, restructuring costs associated with efficiency initiatives and rebranding expenses relative to first quarter 2019. This expense decrease was somewhat offset by an increase in pension expense.

Non-Strategic

The non-strategic segment had pre-tax income of $2.6 million in first quarter 2020 compared to $9.2 million in first quarter 2019. The decrease in results for first quarter 2020 was driven by a smaller provision credit and a decline in NII relative to first quarter 2019 somewhat offset by a decrease in expenses.

Total revenue was $6.0 million in first quarter 2020 down from $9.9 million in first quarter 2019. NII decreased to $5.1 million in first quarter 2020 from $9.1 million in first quarter 2019, primarily due to continued run-off of the loan portfolios. Noninterest income was $.9 million in first quarter 2020 and 2019.

The provision for loan losses within the non-strategic segment was a provision credit of $.4 million in first quarter 2020 compared to a provision credit of $4.4 million in the prior year. The reduction in provision credit in first quarter 2020 was due to additional consumer reserves associated with a sudden, steep decline in economic forecast attributable to the COVID-19 pandemic.

Noninterest expense decreased 27 percent to $3.8 million in first quarter 2020 from $5.2 million in first quarter 2019.

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 82

Income Statement Review

Total consolidated revenue was $477.6 million in first quarter 2020, up 10 percent from $435.6 million in first quarter 2019 driven by a 24 percent increase in noninterest income and a 3 percent increase in NII. Provision expense increased significantly from $9.0 million in first quarter 2019 to $145.0 million in first quarter 2020 primarily driven by a sudden, steep decline in the economic forecast attributable to the COVID-19 pandemic. Total consolidated expenses increased 5 percent to $311.3 million in first quarter 2020 from $296.1 million in first quarter 2019, driven by an increase in expense on unfunded commitments and higher personnel-related expenses, somewhat offset by lower restructuring and rebranding related expenses.

Net Interest Income

Net interest income was $302.8 million in first quarter 2020, up from $294.5 million in first quarter 2019. The increase in NII was primarily attributable to strong loan and deposit growth, favorable deposit costs, and the maturity of $400 million of senior debt in fourth quarter 2019, somewhat offset by lower loan yields compared to first quarter 2019. Average earning assets increased to $38.8 billion in first quarter 2020 from $36.3 billion in first quarter 2019.

The increase in average earning assets was primarily driven by increases in loans, securities purchased under agreement to resell ("asset repos"), and fixed income inventory, somewhat offset by decreases in interest-bearing cash.

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 3.16 percent in first quarter 2020 down 15 basis points from 3.31 percent in first quarter 2019. The net interest spread was 2.89 percent in first quarter 2020, down 3 basis points from 2.92 percent in first quarter 2019. The decrease in NIM in first quarter 2020 was primarily the result of the negative impact of interest rates (including LIBOR and Prime) relative to first quarter 2019. Additionally, higher balances of trading securities negatively impacted NIM in first quarter 2020, but was somewhat mitigated by loan and deposit growth, lower balances of cash held at the Fed, and the maturity of $400 million of senior debt in fourth quarter 2019.

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. For 2020, NIM will also depend on potentially modest loan growth, rate impact from the elevated spread of LIBOR to Fed Funds, widening credit spreads, PPP fees, Fixed Income trading inventory and the extent of assets moving to nonaccrual status.

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 expected credit losses in the loan portfolio. Provision expense was $145.0 million in first quarter 2020 calculated under the CECL methodology adopted January 1, 2020, compared to $9.0 million in first quarter 2019 calculated under the “incurred loss” methodology. The increase in provision expense was primarily the result of a sudden, steep decline in the economic forecast attributable to the COVID-19 pandemic, and to a much less extent associated with loan growth. 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 the Asset Quality section in this MD&A.

NONINTEREST INCOME

Noninterest income (including securities gains/(losses)) was $174.8 million in first quarter 2020 and represented 37 percent of total revenue compared to $141.0 million in first quarter 2019 and 32 percent. The increase in noninterest income in first quarter 2020 was primarily driven by higher fixed income revenue, somewhat offset by a decrease in deferred compensation income relative to first quarter 2019.

Fixed Income Noninterest Income

Fixed income noninterest income was $95.6 million in first quarter 2020, a 78 percent increase from $53.7 million in first quarter 2019. The increase in first quarter 2020 was largely driven by elevated levels of commissionable revenues, partially offset by elevated levels of trading losses driven by extreme market volatility in March 2020. Revenue from other products increased 86 percent to $17.3 million in first quarter 2020 from $9.3 million in first quarter 2019, primarily driven by increases in derivative sales.

Th e following table summarizes FHN’s fixed income noninterest income for the three months ended March 31, 2020 and 2019 .

Other product revenue	17,281	9,277	86 %
Total fixed income noninterest income	$ 95,635	$ 53,749	78 %

Brokerage, Management Fees and Commissions

Noninterest income from brokerage, management fees and commissions increased 22 percent or $2.8 million from $12.6 million in first quarter 2019 to $15.4 million in first quarter 2020. The increase in first quarter 2020 was primarily driven by higher advisory revenue and annuity income as a result of increased transaction volume.

Deposit Transactions and Cash Management

Fees from deposit transactions and cash management activities were $30.3 million in first quarter 2020, down 4 percent from $31.6 million in first quarter 2019. The decrease in first quarter 2020 is largely due to lower debit

card transaction fees as a result of volume incentives received in 2019 and lower NSF/overdraft fee income driven by changes in consumer behavior relative to first quarter 2019, somewhat offset by an increase in fees from cash management activities.

Other Noninterest Income

Other income includes revenues related to other service charges, ATM and interchange fees, mortgage banking (primarily within the non-strategic and regional banking segments), letters of credit fees, dividend income, electronic banking fees, insurance commissions, gain/(loss)

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 85

on the extinguishment of debt, deferred compensation plans (which are mirrored by changes in noninterest expense) and various other fees.

Revenue from all other income and commissions decreased to $14.4 million in first quarter 2020 from $24.6 million in first quarter 2019. The decrease in all other income and commissions in first quarter 2020 was largely due to a $15.0 million decrease in deferred compensation income driven by negative equity market valuations. Deferred compensation income fluctuates with changes in the market value of the underlying investments and is mirrored

by changes in deferred compensation expense which is included in personnel expense. An increase in other service charges and higher fees from derivative sales relative to first quarter 2019 offset a portion of the overall decline in other noninterest income.

The following t able provides detail regarding FHN’s other income.

(b) Amounts are driven by market conditions and are mirrored by changes in deferred compensation expense which is included in employee compensation expense. First quarter 2020 decrease was driven by negative equity market valuations.

NONINTEREST EXPENSE

Total noninterest expense increased to $311.3 million in first quarter 2020 from $296.1 million in first quarter 2019. The increase in noninterest expense in first quarter 2020 was primarily driven by an increase in credit expense on unfunded commitments associated with a sudden, steep decline in economic forecast attributable to the COVID-19 pandemic.

To a lesser extent, higher personnel-related expense also contributed to the increase in noninterest expense, somewhat offset by restructuring costs associated with the identification of efficiency opportunities within the organization, strategic initiatives and rebranding expenses recognized in first quarter 2019.

Employee Compensation, Incentives, and Benefits

Employee compensation, incentives, and benefits (personnel expense), the largest component of noninterest expense, increased 3 percent in first quarter 2020 to $183.5 million from $177.9 million in first quarter 2019. The increase in personnel expense in first quarter 2020 was primarily driven by higher variable compensation due to increased commissionable revenues within Fixed Income.

These expense increases were somewhat offset by a $16.6 million decrease in deferred compensation expense driven by negative equity market valuations in first quarter 2020 and a $6.4 million decrease in restructuring costs associated with the identification of efficiency opportunities within the organization.

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 86

Professional Fees

Professional fees decreased 43 percent or $5.3 million from $12.3 million in first quarter 2019 to $7.0 million in first quarter 2020. The decrease in professional fees was primarily driven by lower restructuring costs associated with the identification of efficiency opportunities within the organization. Additionally, strategic investments recognized in first quarter 2019 to analyze growth potential and product mix for new markets also contributed to the year-over-year decline in professional fees.

FDIC premium expense

FDIC premium expense increased 58 percent from $4.3 million in first quarter 2019 to $6.7 million in first quarter 2020 driven by balance sheet growth and expected loss severity ratios.

Contract employment and outsourcing

Expenses associated with contract employment and outsourcing increased 46 percent or $1.6 million to $4.9 million in first quarter 2020 compared to $3.4 million in first quarter 2019, primarily driven by merger and acquisition related projects.

Other Noninterest Expense

Other expense includes expenses associated with unfunded commitments, travel and entertainment, other insurance and tax expenses, expenses associated with the non-service components of net periodic pension and post-retirement cost, supplies, customer relation expenses, costs associated with employee training and dues, miscellaneous loan costs, tax credit investments expenses, losses from litigation and regulatory matters, expenses associated with OREO, and various other expenses.

All other expenses increased 72 percent to $33.2 million in first quarter 2020 from $19.3 million in first quarter 2019. The increase was primarily driven by an $8.8 million increase in credit expense on unfunded commitments largely associated with the application of CECL methodology with a sudden, steep decline in economic forecast attributable to the COVID-19 pandemic. Additionally, a $2.1 million increase in pension-related costs and $1.0 million of additional credit risk adjustments on Regional Banking interest rate derivatives and swap participations also contributed to the overall increase in all other expenses in first quarter 2020 related to prior year.

INCOME TAXES

F HN recorded an income tax provision of $4.8 million in first quarter 2020 , compared to $27.1 million in first

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 87

quarter 2019 . The effective tax rate for the three months ended March 31, 2020 was approximately 22 percent compared to 21 percent for the three months ended March 31, 2019 .

The Company’s effective tax rate is favorably affected by recurring items such as bank-owned life insurance, tax-exempt income, and credits and other tax benefits from affordable housing investments. The effective rate is unfavorably affected by the non-deductibility of a portion of the Company's FDIC premium and executive compensation expenses. The Company’s effective tax rate also may be affected by items that may occur in any given period but are not consistent from period to period, such as changes in the deferred tax asset valuation allowance and changes in unrecognized tax benefits.

A deferred tax asset (“DTA”) or deferred tax liability (“DTL”) is recognized for the tax consequences of temporary differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. The tax consequence is calculated by applying enacted statutory tax rates, applicable to future years, to these temporary differences. As of March 31, 2020 , FHN’s gross DTA (net of a valuation allowance) and gross DTL were $292.8 million and $207.6 million, respectively, resulting in a net DTA of $85.2 million at March 31, 2020 , compared with a net DTA of $69.0 million at December 31, 2019.

As of March 31, 2020 , FHN had deferred tax asset balances related to federal and state income tax carryforwards of $37.5 million and $1.2 million, respectively, which will expire at various dates.

FHN believes that it will be able to realize the value of its DTA and that no valuation allowance is needed. FHN monitors its DTA and the need for a valuation allowance on a quarterly basis.

RESTRUCTURING, REPOSITIONING, AND EFFICIENCY INITIATIVES

Beginning in 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 immaterial in first quarter 2020 compared to $12.2 million in first quarter 2019. These expenses are primarily associated with severance and other employee costs and professional fees. 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 17 - Restructuring, Repositioning, and Efficiency for additional information.

Statement of Condition Review

Total period-end assets were $47.2 billion on March 31, 2020 , up 9 percent from $43.3 billion on December 31, 2019. The increase in period-end assets was primarily driven by strong loan growth. Additionally, a net increase in other earning assets (primarily trading securities), derivative assets and FHLB stock also contributed to the increase in period-end assets. These increases were somewhat offset by an increase in the allowance for loan losses due to the Adoption of ASU 2016-13, “Measurement of Credit Losses on Financial Instruments,” or (“CECL”) and all related ASUs on January 1, 2020 and additional reserves recognized in first quarter 2020 due to a sudden, steep decline in the economic forecast attributable to the COVID-19 pandemic. Average assets increased 2 percent to $43.6 billion in first quarter 2020 from $42.9 billion in fourth quarter 2019. The increase in average assets was driven by higher balances of trading securities and securities purchased under agreements to resell (“asset repos”), somewhat offset by lower average loan balances and an increase in the ALLL due to the adoption of CECL.

Total period-end liabilities were $42.1 billion on March 31, 2020 , a 10 percent increase from $38.2 billion on December 31, 2019. The net increase in period-end liabilities was primarily due to increases in deposits and

higher balances of short-term borrowings. In first quarter 2020, average liabilities increased to $38.5 billion from $37.8 billion in fourth quarter 2019. The increase in

average liabilities was largely driven by higher balances of short-term borrowings somewhat offset by a decrease in federal funds purchased (“FFP”) relative to fourth quarter 2019.

EARNING ASSETS

Earning assets consist of loans, investment securities, loans HFS, and other earning assets such as trading securities and interest-bearing cash. Average earning assets increased 1 percent and 7 percent to $38.8 billion in first quarter 2020 from $38.2 billion and $36.3 billion, respectively, in fourth quarter 2019 and first quarter 2019. A more detailed discussion of the major line items follows.

Loans

Period-end loans increased 7 percent and 19 percent to $33.4 billion as of March 31, 2020 from $31.1 billion on December 31, 2019 and $28.0 billion as of March 31, 2019 . The increase is period-end loan balances compared to December 31, 2019 was primarily due to an increase in

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 88

loans to mortgage companies during the end of March and additional commercial line draws. Average loans for first quarter 2020 were $30.5 billion compared to $30.7 billion

in fourth quarter 2019 and $27.3 billion in first quarter 2019.

(b) In first quarter 2020, the Permanent Mortgage portfolio was combined into Consumer Real Estate portfolio, all prior periods were revised for comparability.

C&I loans are the largest component of the loan portfolio comprising 64 percent of total loans in both first quarter 2020 and fourth quarter 2019. C&I loans declined 1 percent, from fourth quarter 2019 largely driven by lower balances within mortgage warehouse lending, partially mitigated by strong loan growth within other commercial portfolios of Regional Banking. Growth in other specialty lending areas, such as franchise finance, private client, asset based lending, and healthcare also offset a portion of the overall decline in average C&I loans in first quarter 2020 compared to fourth quarter 2019.Commercial real estate loans experienced a net increase of 4 percent to $4.4 billion in first quarter 2020.

Average consumer loans declined 1 percent from fourth quarter 2019 to $6.6 billion in first quarter 2020, largely driven by the continued wind-down of portfolios within the Non-strategic segment and declines in home equity lines of credit within the Regional Banking segment.

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 available-for-sale (“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. Period-end investment securities we re $4.6 billi on on March 31, 2020 compared to $4.5 billion on December 31, 2019.

Average investment securities were $4.5 billi on in first quarter 2020 and $4.4 billion in fourth quarter 2019, representing 12 percent of average earning assets in first quarter 2020 and fourth quarter 2019. The increase in period-end and average investment securities was driven by FHN's reinvestment strategy in 2020. FHN manages the size and mix of the investment portfolio to assist in asset

liability management, provide liquidity, and optimize risk adjusted returns.

Loans Held-for-Sale

Loans HFS consists of small business, other consumer loans, the mortgage warehouse, USDA, student, and home equity loans. On March 31, 2020 , loans H FS were $595.6 million and $593.8 million, respectively. The average balance of loans HFS increased to $590.5 million in first quarter 2020 from $581.8 million in fourth quarter 2019. The increase in period-end and average loans HFS was primarily driven by an increase in small business loans, somewhat offset by a decrease in USDA loans.

Other Earning Assets

Other earning assets include trading securities, securities purchased under agreements to resell ("asset repos"), federal funds sold (“FFS”), and interest-bearing deposits with the Fed and other financial institutions. Other earning a ssets averaged $3.2 billion in first quarter 2020, a 28 percent increase from $2.5 billion in fourth quarter 2019. The increase in average other earning assets was primarily driven by increases in fixed income trading inventory and asset repos relative to fourth quarter 2019. Fixed income's trading inventory fluctuates daily based on customer demand. 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. Other earning assets were $3.1 billion on March 31, 2020 , up from $2.5 billion on December 31, 2019, primarily driven by increases in fixed income trading inventory and interest-bearing cash.

Th e following table summarizes FHN's average other earning assets for quarters-ended March 31, 2020 and December 31, 2019.

Non-earning assets

Period-end non-earning assets were $5.5 billion and $4.7 billion on March 31, 2020 and December 31, 2019, respectively, driven largely by increases in derivative assets, equity investments (primarily FHLB stock), and fixed income receivables, partially offset by an increase in the ALLL and a decrease in cash balances. Derivative assets and fixed income receivable balances were higher as a result of extreme market volatility during first quarter 2020 and an increase in required margin posting. The increase in the ALLL was due to the adoption of ASU 2016-13 (CECL) on January 1, 2020 and additional reserves established during first quarter 2020 associated with a sudden, steep decline in the economic forecast attributable to the COVID-19 pandemic.

Deposits

Average deposits increased to $32.9 billion during first quarter 2020 from $32.8 billion in fourth quarter 2019 and $32.5 billion in first quarter 2019. The increase in average deposits from fourth quarter 2019 was driven by a seasonal influx of consumer deposits (both non-interest bearing and interest bearing), coupled with an increase in market-indexed deposits, partially offset by lower commercial interest deposits. The increase in first quarter 2020 relative to first quarter 2019 was driven by increases in non-interest

bearing and consumer interest deposits as a result of FHN’s strategic focus on growing deposits during 2019, partially offset by decreases in commercial interest and market-indexed deposits. FHN's mix of interest-bearing deposits and noninterest-bearing deposits remained relatively consistent between periods.

Period-end deposits increased 6 percent to $34.4 billion on March 31, 2020, from $32.4 billion on December 31, 2019 and $32.5 billion on March 31, 2019. The increase in deposits from December 31, 2019 and March 31, 2019 was largely the result of management’s decision to increase market-indexed deposits (given the favorable benefits of this funding source in lower interest-rate environments) to fund loan growth, as well as significant deposit inflows in March 2020 as brokerage customers exited equity markets to move in cash positions given the market volatility associated with the COVID-19 pandemic.

Th e following table summarizes FHN's average deposits for quarters-ended March 31, 2020 and December 31, 2019.

Short-Term Borrowings

Short-term borrowings (federal funds purchased (“FFP”), securities sold under agreements to repurchase, trading liabilities, and other short-term borrowings) averaged $4.0 billion in first quarter 2020, up 20 percent from $3.3 billion in fourth quarter 2019. As noted in the table below, the increase in short-term borrowings between first quarter 2020 and fourth quarter 2019 was primarily driven by increases in other short-term borrowings and trading liabilities, partially offset by a decrease in FFP. 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 fluctuates based on expectations of customer demand. FFP fluctuates depending on the amount of excess funding of FHN’s correspondent bank customers. Period-end short-term borrowings increased 44 percent to $5.8 billion on March 31, 2020 from $4.0 billion on December 31, 2019, primarily driven by an increase in other short-term borrowings, somewhat offset by a decreases in FFP. The increase in short-term borrowings was used to fund commercial loan growth including an uptick in loans to mortgage companies in the latter part of the quarter.

Term Borrowings

Term borrowings include senior and subordinated borrowings with original maturities greater than one year. Average term borrowings were $.8 billion in first quarter 2020 and $.9 billion in fourth quarter 2019. Period-end term borrowings we re $.8 billion on March 31 , 2020 and December 31, 2019. In April 2020, First Horizon Bank issued $450 million of subordinated notes.

Other Liabilities

Period-end other liabil ities were $1.2 billion on March 31 , 2020, up from $1.0 billion on December 31, 2019, primarily driven by increases in derivative liabilities and fixed income payables.

Capital

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 decreased $20.4 million from $5.1 billion on December 31, 2019 to $5.1 billion on March 31, 2020. Average equity decreased $37.5 million to $5.0 billion in first quarter 2020 from $5.0 billion in fourth quarter 2019. The decrease in period-end and average equity was largely attributable to the adoption impact of ASU 2016-13 (CECL) which

resulted in a net decrease to retained earnings of $96.1 million on January 1, 2020, coupled with common and preferred dividends paid, somewhat offset by net income recognized since fourth quarter 2019. A decrease in accumulated other comprehensive income ("AOCI"), largely the result of an increase in unrealized gains associated with AFS debt securities partially mitigated the decrease in period-end and average equity.

(a) The modified CECL transitional amount is calculated as defined in the CECL interim final rule issued by the banking regulators on March 27, 2020 and includes the full amount of the impact to retained earnings from the initial adoption of CECL plus 25 percent of the change in the adjusted allowance for credit losses (“AACL”) since FHN’s initial adoption of CECL through March 31, 2020.

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

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 92

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 March 31, 2020 , each of FHN and First Horizon Bank had sufficient capital to qualify as well-capitalized institutions. FHN also had sufficient capital to meet the capital conservation buffer requirement while First Horizon Bank fell slightly below based on its Total Capital Ratio. (See discussion on dividend limitations for First Horizon Bank in the “Liquidity Risk Management” section of this MD&A.) In April 2020, First Horizon Bank generated additional Tier 2 capital through the issuance of $450 million of subordinated notes. The first quarter 2020 capital ratios for both FHN and First Horizon Bank are calculated under the interim final rule issued by the banking regulators in late March 2020 to delay the effects of CECL on regulatory capital for two years, followed by a three-year transition period. For both FHN and First Horizon Bank, the risk-based regulatory capital ratios decreased in first quarter 2020 relative to fourth quarter 2019 primarily due to increased risk-weighted assets due to period-end commercial loan growth (primarily loans to mortgage companies) and higher draw activity in March, coupled with an increase in market risk assets driven by a spike in VaR due to extreme volatility in March. During 2020, capital ratios are expected to remain above well-capitalized standards.

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.

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 March 31, 2020, $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.

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 March 31, 2020, the

maximum number of shares that may be purchased under the program was 24.3 million shares. Management currently does not anticipate purchasing a material number of shares under this authority during 2020.

Asset Quality

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; and credit card and other. In first quarter 2020, FHN consolidated its permanent mortgage portfolio into consumer real estate. Loans previously classified in permanent mortgage included p rimarily jumbo mortgages and one-time-close (“OTC”) completed construction loans in the non-strategic segment that were originated through pre-2009 mortgage businesses. FHN has a concentration of residential real estate loans (19 percent of total loans). Industry concentrations are discussed under the heading C&I below.

Consolidated key asset quality metrics for each of these portfolios can be fou nd in Table 17 – Asset Q uality by Portfolio. Credit underwriting guidelines are outlined in Exhibit 13 to FHN’s Annual Report on Form 10-K for the year ended December 31, 2019, in the Loan Portfolio Composition discussion in the Asset Quality Section

beginning on page 67 and continuing to page 87. FHN’s credit underwriting guidelines and loan product offerings as of March 31, 2020 , are generally consistent with those reported and disclosed in the Company’s Form 10-K for the year ended December 31, 2019.

COMMERCIAL LOAN PORTFOLIOS

C&I

The C&I portfolio was $22.1 billion on March 31, 2020 , 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 cr edit. The largest geographical concentrations of balances as of March 31, 2020, are in Tennessee (29 percent), North Carolina (10 percent), California (9 percent), Texas (6 percent), Florida (6 percent), Georgia (4 percent), South Carolina (3 percent), and Virginia (3 percent), with no other state representing more than 3 percent of the portfolio.

The following table provides the composition of the C&I portfolio by industry as of March 31, 2020 , and December 31, 2019. For purposes of this disclosure, industries are determined based on the North American Industry Classification System (“NAICS”) industry codes used by Federal statistical agencies in classifying business establishments for the collection, analysis, and publication of statistical data related to the U.S. business economy.

(b) Industries in this category each comprise less than 5 percent for 2020 .

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. 39 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 in dustry. Except “Finance and Insurance” and “Loans to Mortgage Companies”, as discussed below, on March 31, 2020 , 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 companie s was 26 perc ent of the C&I portfolio as of March 31, 2020 , 2 2 percent as of December 31, 2019 and 13 percent as of March 31, 2019 , 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. In periods of economic uncertainty, this trend may not occur even if interest rates are declining. In first quarter 2020, 46 percent of the loans funded were home purchases and 54 percent were refinance transactio ns.

Finance and Insurance

The finance and insurance component represent s 13 p ercent of the C&I portfolio as of March 31, 2020 compared to 14 percent as of December 31, 2019, 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 March 31, 2020 , asset-based lending to consumer finance companies represents ap proximately $1.2 billion o f 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. 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 March 31, 2020 , no TRUP relationship was on interest deferral.

As of March 31, 2020 , the unpaid principal balance (“UPB”) of trust preferred loans totaled $234.2 million ($173.6 million of bank TRUPS and $60.7 million of insurance TRUPS) with the UPB of other bank-related loans totaling $282.3 million. Inclusive of a valuation allowance on TRUPS of $18.9 million, total reserves (ALLL plus the valuation allowance) for TRUPS and other bank-related loans were $29.9 million or 6 percent of outstanding UPB.

C&I Asset Quality Trends

The C&I portfolio trends remained stable in first quarter 2020; however, the impact of economic uncertainty attributable to the COVID-19 pandemic could negatively impact future trends. The C&I ALLL increased $132.0 million from December 31, 2019, to $254.5 million as of March 31, 2020 , primarily due to the sudden, steep decline

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 95

in the economic forecast attributable to the COVID-19 pandemic and the adoption of ASU 2016-13.

The allowance as a percentage of period-end loans increased 54 basis points to 1.15 percent as of March 31, 2020 , compared to .61 percent as of year-end 2019. Nonperforming C&I loans increased $21.8 million from December 31, 2019, to $96.1 million on March 31, 2020 . The nonperforming loan (“NPL”) ratio increased to .43 percent of C&I loans as of March 31, 2020 , from .37 percent as of December 31, 2019. The increase in NPLs was primarily driven by one credit.

The 30+ delinquenc y ratio increased 3 basis points to .08 percent as of March 31, 2020 . First quarter 2020 experienced net charge-offs of $5.8 million compared to $3.3 million and $2.3 million of net charge-offs in fourth quarter 2019 and first quarter 2019, respectively. First quarter 2020 net charge-offs were primarily driven by one credit.

Commercial Real Estate

The CRE portfolio was $4.6 billion on March 31, 2020 . The CRE portfolio includes both financings for commercial construction and nonconstruction loans. The largest geographical concentrations of balances as of March 31, 2020 are in North Carolina (28 percent), Tennessee (20 percent), Florida (13 percent), South Carolina (8 percent), Texas (8 percent), Georgia (6 percent), and Kentucky (3 percent), with no other state representing more than 3 percent of the portfolio. This portfolio is segregated between the income-producing CRE class which contains loans, draws on lines and letters of credit to commercial real estate developers for the construction and mini-permanent financing of income-producing real estate, and the residential CRE class. Subcategories of income CRE consist of office (27 percent), multi-family (22 percent), retail (19 percent), industrial (13 percent), hospitality (12 percent), land/land development (1 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 develo ping residential subdivisions. After the fulfillment of existing commitments over the near term, the residential CRE class will be in a wind-down state with the expectation of full runoff in the foreseeable future.

CRE Asset Quality Trends

The CRE portfolio as of March 31, 2020 was not significantly affected by the global COVID-19 pandemic, with nonperforming loans up $.4 million fro m December 31, 2019. However, economic uncertainty attributable to COVID-19 could impact future CRE portfolio trends. The allowance increased to $47.6 million as of March 31, 2020 , from $36.1 million as of December 31, 2019 primarily due to COVID-19. Allowance as a percentage of loans increased 20 basis points from .83 percent as of December 31, 2019, to 1.03 percent as of March 31, 2020 . Nonperforming loans as a percentage of total CRE loans increased 1 basis point from December 31, 2019, to .05 percent as of March 31, 2020 .

Accruing delinquencies as a percentage of period-end loans decreased to .01 percent as of March 31, 2020 , from .02 percent as of December 31, 2019. Net charge-offs were not significant in first quarter 2020 and were $377 thousand in first quarter 2019.

CONSUMER LOAN PORTFOLIOS

Consumer Real Estate

The consumer real estate portfolio was $6.1 billion on March 31, 2020 , and is primarily composed of home equity lines and installment loans including restricted balances (loans consolidated under ASC 810). The largest geographical concentrations of balances as of March 31, 2020 , are i n Tennessee (55 percent), North Carolina (15 percent), Florida (14 percent), and California (3 percent), with no other state represen ting more than 3 percent of the portfoli o. As of March 31, 2020 , approximately 85 p ercent of the consumer real estate portfolio was in a first lien position. At origination, weighted average FICO score of this portfolio was 755 and refreshed FICO scores averaged 754 on March 31, 2020 . Generally, perform ance 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 March 31, 2020 . 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 March 31, 2020 , approximately 78 pe rcent of FHN's HELOCs are in the draw period compared to approximately 76 percent as of December 31, 2019. Based on when draw periods are scheduled to end per the line agreement, it is expected that $306.7 million, or 32 percent o f HELOCs currently in the draw period, will enter the repayment period during the next 60 months. Delinquencies and charge-off rates for HELOCs that have entered the repayment period are initially higher than HELOCs still in the draw period because of the increased minimum payment requirement; however, after some seasoning, performance of these loans usually begins to stabilize. The home equity lines of the consumer real estate portfolio are being monitored closely for those nearing the end of the draw period and borrowers are initially being contacted at least 24 months before the repayment period begins to remind the customer of the terms of their agreement and to inform them of options.

The following table shows the HELOCs currently in the draw period and expected timing of conversion to the repayment period.

C onsumer Real Estate Asset Quality Trends

Overall, performance of the consumer real estate portfolio remained stable in first quarter 2020. Economic uncertainty attributable to COVID-19 could impact future trends. The non-strategic segment is a run-off portfolio and while the absolute dollars of delinquencies and nonaccruals as well as the 30+ accruing delinquencies ratio improved from year-end, 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 and some of the stronger borrowers payoff or refinance elsewhere. NPLs as a percentage of loans increased 10 basis point from year-end to 1.49 percent as of March 31, 2020 . The ALLL increased $94.6 million from December 31, 2019, to $123.0 million as of March 31, 2020 , primarily due to the adoption of ASU 2016-13. The allowance as a percentage of loans increased 155 basis points to 2.01 percent as of March 31, 2020 , compared to year-end. The balance of nonperforming loans increased $5.5 million to $91.2

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 99

million as of March 31, 2020 . Loans delinquent 30 or more days and still accruing declined from $42.9 million as of December 31, 2019, to $40.1 million as of March 31, 2020 . The portfolio realized net recoveries of $1.2 million in first quarter 2020 compared to net recoveries of $3.3 million in

fourth quarter 2019 and net recoveries of $1.2 million in first quarter 2019.

Credit Card and Other

The credit card and other portfolio, which is primarily within the regional banking segment, was $.5 billion as of March 31, 2020 , and primarily includes credit card receivables, other consumer-related credits, and automobile loans. The allowance increased to $19.3 million as of March 31, 2020 , from $13.3 million as December 31, 2019, primarily driven by the sudden, steep decline in the

economic forecast attributable to the COVID-19 pandemic and the adoption of ASU 2016-13.

Allowance for Loan Losses

Management’s policy is to maintain the ALLL at a level sufficient to recognize current expected credit losses on the amortized cost basis of the loan portfolio. The total allowance for loan losses increased to $444.5 million on March 31, 2020 , from $200.3 million on December 31, 2019. The ALLL as of March 31, 2020 , reflects the adoption of ASU 2016-13 on January 1, 2020 and the sudden, steep decline in the economic forecast attributable to the COVID-19 pandemic. The ratio of allowance for credit losses to total loans, net of unearned income, increase 69 basis points to 1.33 percent on March 31, 2020 , compared to .64 percent on December 31, 2019.

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 current expected losses on the amortized cost basis of the loan portfolio. Provision expense was $145.0 million in first quarter 2020, compared to $9.0 million provision expense in first quarter 2019. The increase is primarily attributable to the declining economic forecast attributable to the COVID-19 pandemic.

FHN expects asset quality trends to be impacted by the economic uncertainty attributable to the COVID-19 pandemic. The C&I portfolio reflects a broad mix of categories with the heaviest concentration in loans to mortgage companies which carry minimal credit risk. The CRE portfolio metrics could be impacted by the COVID-19 pandemic due to travel and occupancy restrictions set by state and local governments affecting CRE- Hospitality and CRE-Retail. The consumer portfolio could be impacted by the COVID-19 pandemic if consumer unemployment continues to rise and customers are unable to continue making loan payments. The consumer portfolio however is high quality with no subprime and minimal exposure to high risk lending. The remaining non-strategic consumer real estate should continue to steadily wind down; however, it could be impacted if unemployment continues to rise and borrowers have difficulty making loan payments. Asset quality metrics within non-strategic have become skewed as the portfolio continues to shrink.

Consolidated Net Charge-offs

In first quarter 2020, FHN experienced net charge-offs of $7.2 million compared to $4.5 million of net charge-offs in first quarter 2019.

The commercial portfolio experienced $5.8 million of net charge-offs in first quarter 2020 compared to $2.6 million in net charge-offs in first quarter 2019. In addition, the consumer real estate portfolio experienced net recoveries of $1.2 million in both first quarter 2020 and first quarter 2019. Credit card and other consumer experienced net charge-offs of $2.6 million in first quarter 2020 compared to $3.1 million a year ago.

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 in which 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 $207.3 million on March 31, 2020 , from $181.9 million on December 31, 2019. The nonperforming assets ratio (nonperforming assets excluding NPLs HFS to total period-end loans plus OREO and other assets) increased to .61 percent as of March 31, 2020 , from .57 percent as of December 31, 2019. Portfolio nonperforming loans increased to $189.8 million as of March 31, 2020 , from $162.2 million as of December 31, 2019. The increase in nonperforming loans was driven by the C&I portfolio.

The ratio of the ALLL to NPLs in the loan portfolio was 2.34 times as of March 31, 2020 , compared to 1.24 times as of December 31, 2019. Certain nonperforming loans in both the commercial and consumer portfolios are deemed collateral-dependent and are charged down to an estimate of collateral value less costs to sell. Because loss content has been recognized through a partial charge-off, typically reserves are not recorded.

Table 19 provides an activity rollforward of OREO balances for March 31, 2020 and 2019. The balance of OREO, exclusive of inventory from government insured mortgages, decreased to $13.9 million as of March 31, 2020 , f rom $20.7 millio n as of March 31, 2019 , driven by the sale of OREO. Moreover, property values have stabilized which also affects the balance of OREO.

Past Due Loans and Potential Problem Assets

Past due loans are loans co ntractually 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 $14.1 million on March 31, 2020 , compared to $21.9 million on December 31, 2019. Loans 30 to 89 days past due were $48.5 million on March 31, 2020 , compared to $36.1 million on December 31, 2019. The increase was primarily driven by the C&I portfolio.

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 Federal banking regulators for loans classified as substandard. Potential problem assets in the loan po rtfolio were $411.1 million on March 31, 2020 , $346.9 million on December 31, 2019, and $270.4 million on March 31, 2019 . The increase in potential problem assets compared to December 31, 2019 was due to 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 adequ acy 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.

On March 31, 2020 and December 31, 2019, FHN had $194.7 million and $206.3 million portfolio loans classified as TDRs, respectively. For TDRs in the loan portfolio, FHN had loan loss reserves of $13.9 million and $19.7 million, or 7 percent and 10 percent of TDR balances, as of March 31, 2020 and December 31, 2019, respectively. Additionally, FHN had $50.5 million and $51.1 million of HFS loans classified as TDRs as of March 31, 2020 and December 31, 2019, respectively.

Risk Management

There have been no significant changes to FHN’s risk management practices as described under “Risk Management” beginning on page 88 of Item 7 to FHN’s Annual Report on Form 10-K for the year ended December 31, 2019.

MARKET RISK MANAGEMENT

There have been no significant changes to FHN’s market risk management practices as described under “Market Risk Management” beginning o n page 89 of Item 7 to FHN’s Annual Report on Form 10-K for the year ended December 31, 2019.

Value-at-Risk (“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. 1Q20 FORM 10-Q REPORT 106

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

First quarter 2020 VaR and SVaR increased due to extreme volatility as a result of economic uncertainty associated with the COVID-19 pandemic.

FHN’s overall VaR measure includes both interest rate risk and credit spread risk. Separate measures of these component risks are as follows:

Table 22—Schedule of Risks Included in VaR

(Dollars in thousands)	As of March 31, 2020 — 1-day	10-day	As of March 31, 2019 — 1-day	10-day	As of December 31, 2019 — 1-day	10-day
Interest rate risk	$ 1,255	$ 2,628	$ 560	$ 1,412	$ 693	$ 3,929
Credit spread risk	2,301	11,758	398	726	417	828

First quarter 2020 VaR and SVaR increased due to extreme volatility as a result of economic uncertainty associated with the COVID-19 pandemic.

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

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 107

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

There have been no significant changes to FHN's interest rate risk management practices as described under "Interest Rate Risk Management" beginning o n page 90 o f Item 7 to FHN's Annual Report on Form 10-K for the year ended December 31, 2019.

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 March 31, 2020 , 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 2.2 percent, 3.5 percent, 5.1 percent, and 6.5 percent, respectively compared to base NII. A steepening yield curve scenario where long-term rates increase by 50 basis points and short-term rates are static, results in a favorable NII variance of 1.7 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 1.9 percent. Rate shocks of minus 25 basis points and 50 basis points result in unfavorable NII variances of 4.1 percent and 8.7 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 March 2020, the Federal Reserve lowered the Fed Funds range to 0.00% - 0.25%. However, due to

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 108

dislocation in the short end of the curve, LIBOR has remained elevated compared to the Fed Funds rate. As most of FHN’s assets are indexed to LIBOR while most of FHN’s floating liabilities are indexed to Fed Funds, this has a material impact on the shock scenarios.

FHN’s net interest income may be impacted by the disruption from the recent COVID-19 crisis. The increase in the unemployment rate, customer loan deferral requests, the impact of government assistance programs, and other developments could influence net interest income results. FHN is monitoring the current economic situation and potential exposures closely.

CAPITAL RISK MANAGEMENT AND ADEQUACY

There have been no significant changes to FHN's capital management practices as described under "Capital Risk Management and Adequacy" on pa ge 91 of Item 7 to FHN's Annual Report on Form 10-K for the year ended December 31, 2019.

OPERATIONAL RISK MANAGEMENT

There have been no significant changes to FHN's operational risk management practices as described under "Operational Risk Management" beginning on p age 91 of Item 7 to FHN's Annual Report on Form 10-K for the year ended December 31, 2019.

COMPLIANCE RISK MANAGEMENT

There have been no significant changes to FHN's compliance risk management practices as described under "Compliance Risk Management" on page 92 of Item 7 to FHN's Annual Report on Form 10-K for the year ended December 31, 2019.

CREDIT RISK MANAGEMENT

There have been no significant changes to FHN's credit risk management practices as described under "Credit Risk Management" beginning on page 92 of Item 7 to FHN's Annual Report on Form 10-K for the year ended December 31, 2019.

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 ($2.1 billion wa s available at March 31, 2020 ), brokered deposits, loan sales, syndications, and access to the Federal Reserve Bank.

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 100 percent on March 31, 2020 co mpared to 98 percent on December 31, 2019.

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 April 2020, First Horizon Bank issued $450 million of subordinated notes. These subordinated notes qualify as Tier 2 capital for First Horizon Bank as well as FHN, up to certain regulatory limits for minority interest capital instruments.

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 109

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 March 31, 2020 , First Horizon Bank and subsidiaries had outstanding preferred shares of $295.4 million, which are reflected as noncontrolling interest on the Consolidated Condensed 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 ‘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 $294.7 million as of April 1, 2020. Additionally, a capital conservation buffer of 50 basis points above well-capitalized levels (equal to an extra 2.5 percent above minimum levels) must be maintained on the Common Equity Tier 1, Tier 1 Capital and Total Capital ratios to avoid restrictions on dividends. Since the Total Capital ratio for First Horizon Bank fell slightly below the required buffer as of March 31, 2020, these capital conservation buffer rules limit the amount of dividends that the Bank can declare in second quarter 2020 to its sole common stockholder, FHN, or to its preferred shareholders without prior regulatory approval at $70.9 million. First Horizon Bank declared and paid common dividends to the parent company in the amount of $65 million in first quarter 2020 and $345.0 million in 2019. First Horizon Bank declared and paid preferred dividends in first quarter 2020 and each quarter of 2019. Additionally, First Horizon Bank declared preferred dividends in second quarter 2020, payable in July 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. FHN is subject to the capital conservation buffer requirements as described in the above paragraph for First Horizon Bank. 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 $.15 per common share on April 1, 2020, and in April 2020 the Board approved a $.15 per common share cash dividend payable on July 1, 2020, to shareholders of record on June 12, 2020. FHN paid a cash dividend of $1,550.00 per preferred share on April 10, 2020, and in April 2020 the Board approved a $1,550.00 per preferred share cash dividend payable on July 10, 2020, to shareholders of record on June 25, 2020.

CASH FLOWS

The Consolidated Condensed Statements of Cash Flows provide information on cash flows from operating, investing, and financing activities for the three months ended March 31, 2020 and 2019 . The level of cash and cash equivalents decreased $136.8 million during first quarter 2020 and $192.5 million in first quarter 2019.

Net cash provided in financing activities was $3.7 billion in first quarter 2020, largely driven by an inflow of deposits and higher short-term borrowings (primarily FHLB stock). Net cash used by investing activities was $2.5 billion in first quarter 2020, driven by strong loan growth and an increase in interest-bearing cash. Net cash used by operating activities was $1.4 billion in first quarter 2020 primarily due to net cash outflows of $407.9 million related to loans held-for-sale as purchases and originations outpaced proceeds from sales and settlements, $285.4 million related to fixed income trading activities and $323.8 million related to an increase in derivatives.

Net cash used in financing activities was $222.2 million in first quarter 2019, largely driven by a decrease in deposits, share repurchases and cash dividends paid during first quarter 2019, somewhat offset by an increase in other short-term borrowings, primarily FFP. Net cash used by investing activities was $92.7 million in first quarter 2019, largely driven by increases 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 operating activities was $122.5 million in first quarter 2019 primarily due to net cash inflows of $369.2 million related to fixed income trading activities and favorably driven cash-related

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 110

net income items, somewhat offset by outflows of $358.6 million related to loans held-for-sale.

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 10 - 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 10 - 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

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 111

included in the active pipeline. The 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 $13.5 million on March 31, 2019 from $14.5 million on December 31, 2019.

Market Uncertainties and Prospective Trends

FHN’s future results could be affected both positively and negatively by several known trends. Key among those are changes in the U.S. and global economy and outlook, government actions affecting interest rates, availability and the administration of stimulus relief for the economy and FHN’s customers related to the recent global COVID-19 pandemic, political uncertainty, potential changes in federal policies and the potential impact to our customers, and FHN’s strategic initiatives. 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.

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 directly or indirectly impacted by global events that impact our customers and their businesses. The recent global COVID-19 pandemic has led to periods of significant volatility in financial commodities (including oil and gas) and other markets, has adversely affected FHN’s ability to conduct normal business, has adversely affected FHN customers, and is likely to harm FHN’s business and future results of operations.

In March 2020 the Federal Reserve lowered short-term interest rates twice and started a “quantitative easing” program intended to lower longer-term interest rates and foster access to credit. The effective yields of 10-year and 30-year U.S. Treasury securities achieved record low rates and the U.S. Congress enacted relief legislation which, among other things, is intended to provide emergency credit to businesses at risk for failure from government and public actions related to the COVID-19 pandemic, and to mitigate an economic recession. These changes in interest rates and the volatility in the market are likely to negatively impact FHN’s net interest margin. In the near term, amortization of net processing fees related to government relief programs, including the Paycheck Protection Program ("PPP"), may offset a portion of the net interest margin decline. In addition, credit spreads have widened. For new loans, wider spreads should help mitigate net interest margin compression. However, FHN will not be able to capture the widened spreads quickly for outstanding floating-rate loans.

The economic effects of the COVID-19 pandemic have significantly altered business in the U.S. and globally leading to partial or full business closures, individuals being furloughed or laid off, significant increases in unemployment, and workers being partially or wholly ordered to work from home. Disruption to FHN’s customers due to governmental and societal responses to COVID-19 are likely to adversely affect FHN’s loan and deposit fee income as well as create downward loan migration and a corresponding increase in loan loss expense and reserves. In addition, loan charge-offs likely will increase over time, especially if economic disruption related to COVID-19 continues for more than a few months. Furthermore, government programs under the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) and other guidance intended to provide relief to customers through temporary modifications and deferrals, may in some instances mask or postpone reporting of credit problems and potential defaults. In these circumstances, current credit quality indicators may not be reflective of the underlying health of FHN's portfolios.

Given the ongoing and dynamic nature of the circumstances, it is difficult to predict the impact of the COVID-19 pandemic on the businesses of FHN for the remainder of 2020 or afterward.

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

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 112

effects for applicable securities and derivatives and 4) assess revisions to product pricing structures based on alternative reference rates. In March 2020, the FASB issued ASU 2020-04, “Facilitation of the Effects of Reference Rate Reform on Financial Reporting,” which provides several optional expedients and exceptions to ease the potential burden in accounting for reference rate reform. Refer to the Accounting Changes Issued but Not Currently Effective section of Note 1 - Financial Information for additional information. Additionally, the IRS has released a proposal that is intended to facilitate the transition of existing contracts from LIBOR to new reference rates without triggering modification accounting or taxable exchange treatment for those contracts. This 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.

FHN has prioritized expense discipline to include reducing or controlling certain expenses including realization of expense efficiencies from its 2017 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.

When FHN closes its proposed merger with IBKC, under applicable accounting guidance FHN will be required to record IBKC's loans at estimated fair value as of the closing date. In addition, FHN will be required to assess the current (at that time) expected credit losses associated with IBKC loans. That credit loss assessment will be separate from the fair value estimation, and will result in a charge to FHN's income for certain loans for the period in which closing occurs. FHN is not able make that assessment at this time, but believes that the associated charge to income will be substantial to quarterly income.

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 may 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."

FHN response to the COVID-19 pandemic

As previously mentioned, the COVID-19 pandemic has, and will continue, to directly and indirectly impact FHN and our customers. FHN has adapted many operations to help ensure the health and safety of employees and customers during these uncertain times. Among other things, FHN has implemented remote work policies, branch activities handled by appointment or via drive-through only, as well as additional sick time and child care assistance for employees. Additionally, FHN’s foundation has donated $2.5 million to support community relief efforts.

Loans

FHN is actively monitoring the COVID-19 pandemic and its impact on customers and FHN’s credit quality. In response, FHN is proactively reaching out to customers to discuss challenges and solutions, is providing line draws and new extensions to existing customers, is providing support for small businesses through the PPP (discussed in more detail below) and other stimulus programs, as well as providing lending and deposit assistance through deferrals and waived fees. Additionally, in certain sectors, FHN has reduced or stopped new lending.

Paycheck Protection Program

On March 27, 2020, the CARES Act was signed into law. Sections 1102 and 1106 of the CARES Act include a PPP that made $349 billion of funds available for qualifying businesses to receive fully-guaranteed loans via the Small Business Administration’s Section 7(a) lending program. These loans are potentially fully forgivable, depending upon the borrower’s use of the funds and maintenance of employment levels.

PPP loans are intended to provide cash-flow assistance to nonprofit and small business employers for expenses incurred between February 15, 2020, and June 30, 2020. Generally, the maximum loan amount per qualified borrower is the lesser of 1) 250 percent of average monthly payroll costs (e.g., salaries and wages up to $100,000 and benefits) during the previous one-year period plus the outstanding amount of any existing SBA Economic Injury Disaster Loan made from January 1, 2020 through April 3, 2020, that is being refinanced under the PPP and 2) $10 million. Eligible borrowers include any of the following that were in operation on February 15, 2020:

• Businesses, including nonprofit organizations under Internal Revenue Code (“IRC”) Section 501(c)(3), veterans’ organizations under IRC Section 501(c)(19), and tribal organizations, that

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 113

have 500 or fewer employees (or the Small Business Administration’s employee-based or revenue-based industry size standard, if higher).

• Businesses in the food and accommodations industry (as defined in NAICS 724) with 500 or fewer employees per location.

• Sole proprietors, independent contractors, and self-employed individuals.

All PPP loans carry the same terms which are as follows:

• Fixed interest rate of 1 percent per annum

• Maturity date of two years, with the ability to prepay earlier with no fees

• First payment deferred for six months

• Waiver of “credit elsewhere” SBA 7(a) requirement

• No collateral or personal guarantees required

• No borrower fees charged to obtain such loans

Under Section 1106 of the CARES Act, borrowers are eligible for forgiveness of principal and accrued interest on PPP loans to the extent that the proceeds are used to cover eligible payroll, interest, rent, and utility costs over the eight-week period after the loan is made as long as the borrower retains its employees and their compensation levels. However, no more than 25 percent of loan forgiveness may be attributable to eligible rent, utilities and interest. In addition, loans qualifying for forgiveness will not be included in the borrower’s taxable income.

Lenders making these PPP loans are paid a fee by the Small Business Administration on the date the loans are made. Lender fees are based on the following sliding scale.

• Loans $350,000 and under: 5.00%

• Loans greater than $350,000 to $2 million: 3.00%

• Loans greater than $2 million: 1.00%

Borrowers can use agents to assist in the preparation of their PPP applications. Those agents are paid from the SBA fees received from the originating bank. Additionally, originating banks have certain internal costs of originating PPP loans. For applicable loans, agent fees are paid by originating banks based on the following scale.

• Loans $350,000 and under: 1.00%

• Loans greater than $350,000 to $2 million: 0.50%

• Loans greater than $2 million: 0.25%

The SBA provides a 100 percent guarantee on PPP loans, which is an increase to the existing guarantee percentages under current SBA loan programs. In the event that a lender sells a PPP loan on the secondary market, the guarantee will transfer with the loan. Lenders are not required to conduct any verification regarding loan forgiveness provided that a borrower submits documentation supporting its request for loan forgiveness and attests that it has accurately verified the eligibility of the expenditures made. Lenders will be held harmless if they rely on such documentation. Lenders must make a decision on the forgiveness within 60 days. Section 1106 of the CARES Act indicates that any lender or purchaser of PPP loans may report to the SBA an expected forgiveness amount, and the SBA will purchase the expected forgiveness amounts, plus any interest accrued to date, within 15 days after such requests are received. Requests for forgiveness may occur as early as seven weeks after the loan is originated.

As part of FHN’s efforts to support customers through various stimulus programs, FHN originated 6,761 of PPP loans with an aggregate principal of $1.7 billion in April 2020. For these loans, FHN anticipates recognizing net origination fees of approximately $45 to $50 million. Additional lower origination volumes are anticipated in May. FHN has decided to hold its PPP loans for investment. Therefore, the net amount of SBA fees and total direct origination costs are deferred as a discount to the recorded carrying value of the PPP loans. This discount is being amortized prospectively to interest income. SBA loan forgiveness payments are considered prepayments of the related loans. Under existing accounting principles, amortization of net origination fees can reflect expected prepayment activity if prepayments are determined to be probable and both the timing and volume can be reasonably estimated. Based on the terms of the PPP loans, including the expected end of the payment deferral period, FHN estimates that substantially all of the prepayment-eligible portions of PPP loans will be prepaid in 2020 as these loans are forgiven. These estimated prepayments will result in a similar amount of the net fees being recognized in interest income in 2020.

Since PPP loans carry a full SBA guarantee, they do not have any credit risk and will not affect the amount of provision and ALLL recorded. Consistent with this view, the CARES Act indicates that investors should assign a risk weight of zero to PPP loans for regulatory capital purposes.

The initial funding for the $359 billion PPP loans was exhausted by April 16, 2 020. However, on April 24, 2020, an additional $320 billion of funding was approved for the PPP. These funds will likely be exhausted in early May.

Lending Assistance for Borrowers

Other customer support initiatives include incremental lending assistance for borrowers through delayed payment programs and fee waivers. The following table provides the UPB of loans related to deferrals granted to FHN’s customers that have been processed through April 30, 2020.

(Dollars in thousands)	As of April 30, 2020
Commercial:
General C&I	$ 1,582,903
Loans to mortgage companies	—
TRUPS	—
Income CRE	1,061,452
Residential CRE	1,715
Total Commercial	$ 2,646,070

R/E installment loans	494,205
Credit Card & Other	3,279
Total Consumer	567,015
Total	$ 3,213,085

Commercial deferrals processed are comprised primarily of general commercial (39 percent or $1.0 billion), commercial real estate (28 percent or $731.3 million - primarily within our Mid-Atlantic, Southeast Tennessee,

and Middle Tennessee markets), franchise finance (13 percent or $334.9 million), business banking (8 percent or $208.9 million), and private client (6 percent - $152.0 million).

Deposits

Deposit levels were also significantly impacted in April due to the impacts of COVID-19 pandemic which resulted in an increase in period-end deposits of $3.7 billion, or 11 percent, from March 31, 2020 levels. This increase was due to an increase in commercial deposits as FHN saw many firms deposit funds (from lines of credit, PPP loans, operational revenues, etc.) into non-interest bearing operating accounts in order to increase their liquidity positions. Additionally, as various government stimulus programs were rolled out FHN saw increases in deposits from the Healthcare industry as Medicare reimbursements related to COVID-19 became available and a jump in deposits in Correspondent banking due to stimulus and PPP funds deposited into client banks. Consumer deposit inflows were also impacted by approximately $300 million in initial stimulus payments in mid-April.

Critical Accounting Policies

Except for the changes to the following Allowance for Loan Losses section, there have been no significant changes to FHN’s critical accounting policies as described in “Critical Accounting Policies” beginning on page 99 of Item 7 to FHN’s Annual Report on Form 10-K for the year ended December 31, 2019.

ALLOWANCE FOR LOAN LOSSES

Management’s policy is to maintain the ALLL at a level sufficient to absorb expected credit 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. 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, including evaluation of inherently uncertain future economic conditions, (3) prepayment activity must be projected to estimate of the life of loans that often are shorter than contractual terms, (4) it requires estimation of a reasonable and supportable forecast period for credit losses for loan portfolio segments before reversion to historical loss levels over the remaining life of a loan and (5) expected future recoveries of amounts previously charged off must be estimated. Accordingly, this is a highly subjective process and requires significant judgment since it is difficult to evaluate current and future economic conditions in relation to an overall credit cycle and estimate the timing and extent of loss events that are expected to occur prior to end of a loan’s estimated life. 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) the lives for loan portfolio pools have been estimated properly, including consideration of expected prepayments; (5) the economic forecasts utilized in the modeling of expected credit losses are reflective of future economic conditions; (6) entity-specific historical loss information has been properly assessed for all loan portfolio segments as the

initial basis for estimating expected credit losses; (7) the reasonable and supportable periods for loan portfolio segments have been properly determined; (8) the reversion methodologies and timeframes for migration from the reasonable and supportable period to the use of historical loss rates are reasonable; (9) expected recoveries of prior charge off amounts have been properly estimated; and (10) qualitative adjustments to modeled loss results reasonably reflect expected future credit losses 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.

The “Contingencies” section of Note 10 to the Consolidated Condensed Financial Statements beginning on page 40 of this Report is incorporated into this Item by reference.

Item 1A. Risk Factors

The following supplements Item 1A of our annual report on Form 10-K for the year ended December 31, 2019. It relates to most discussions within that Item, particularly discussions under the captions: “Operational Risks,” “Risks Associated with Economic Downturns and Changes,” “Risks Associated with Monetary Events,” “Reputation Risks,” “Credit Risks,” “Service Risks,” “Regulatory, Legislative, and Legal Risks,” “Risks of Expense Control,” “Insurance,” “Liquidity and Funding Risks,” “Credit Ratings,” “Interest Rate and Yield Curve Risks,” “Asset Inventories and Market Risks,” and “Stockholding and Governance Risks.”

Supplemental Risk Factor Disclosures related to COVID-19

The recent global COVID-19 pandemic has led to periods of significant volatility in financial, commodities (including oil and gas) and other markets, has adversely affected FHN’s ability to conduct normal business, has adversely affected FHN customers, and is likely to harm FHN’s businesses and future results of operations.

In December 2019, a coronavirus (COVID-19) was reported in China, and has since spread to most countries in the world, including the United States. Starting in late February 2020, financial market volatility increased dramatically based on concerns that COVID-19, and the steps being undertaken in many countries to mitigate its spread, would significantly disrupt economic activity.

In March 2020, financial market volatility increased further, with several one-day stock market swings that resulted in significant market declines. Additionally, in March: market pricing deteriorated in virtually all sectors and asset classes except U.S. Treasury securities; the World Health Organization declared COVID-19 to be a pandemic; the U.S. President declared the COVID-19 pandemic to be a national emergency, allowing several federal disaster programs to be accessed by states and cities; many states and cities in the U.S. declared health emergencies, lockdowns, travel restrictions, and quarantines, prohibiting gatherings of more than a small number of people and ordering or urging most businesses and workplaces to close or operate on a very restricted basis; the Federal Reserve lowered short-term interest rates twice and started a “quantitative easing” program intended to lower longer-term interest rates and foster access to credit; the effective yields of 10-year and 30-year U.S. Treasury securities achieved record low rates; and the U.S. Congress enacted relief legislation which, among other things, is intended to provide emergency credit to businesses at risk for failure

from government and public actions related to the COVID-19 pandemic, and to mitigate an economic recession which has not been officially declared but is widely believed to have begun in March. Government programs instituted recently include loan programs administered by banks and other private-sector lenders, liquidity programs administered by the U.S. Treasury, and favorable accounting and regulatory treatment (for lenders) of certain loan payment deferrals.

The economic effects of these and related actions and events in the U.S. have included: large numbers of partial or full business closures; large numbers of people being furloughed or laid off; large increases in unemployment; large numbers of workers being partially or wholly ordered to work from home; large numbers of businesses at risk of insolvency as revenues drop off precipitously, especially in businesses related to travel, leisure, and physical personal services; large numbers of investors realizing substantial losses in their portfolios and retirement funds; and large numbers of consumers being unwilling to undertake significant discretionary spending. In addition, worldwide demand for oil has fallen sharply in conjunction with the pandemic resulting in sharp drops in oil prices and sharp drops in the values of oil-related assets. Further, certain banking organizations globally have limited share buybacks and other capital actions. The most significant effects already experienced by FHN, and actions already taken by FHN, are mentioned in Part I, Item 2 of this report under the captions “Financial Summary,” “Income Statement Review,” “Asset Quality,” and “Market Uncertainties and Prospective Trends,” beginning on pages 81, 83, 94, and 112 of this report, respectively.

Given the ongoing and dynamic nature of the circumstances, it is difficult to predict the impact of the COVID-19 pandemic on the businesses of FHN for the remainder of 2020 or afterward. FHN’s efforts to mitigate

FIRST HORIZON NATIONAL CORP. 1Q20 FORM 10-Q REPORT 118

the adverse impacts of COVID-19 may not be effective, and in any case are likely to be only a partial mitigate. The full extent of impacts resulting from the COVID-19 pandemic and other events beyond the control of FHN will depend on future developments, which are highly uncertain and unpredictable, including new information which may emerge concerning the severity of the pandemic and further actions taken to prevent, treat, or mitigate the spread of COVID-19, among others. Moreover, global markets for oil and gas have been, and may continue to be, severely impacted by events beyond the control of FHN. The current low commodity prices, especially if sustained, could have a negative impact on the economies of several states in which FHN conducts business, as well as FHN’s customers, businesses, and assets in those states.

In addition, the COVID-19 pandemic could result in business disruption to FHN, and if unable to recover from such a business disruption on a timely basis, FHN’s businesses, financial condition, and results of operations would be adversely affected. The efforts to integrate the businesses of IBKC and those of FHN may also be delayed and adversely affected by the COVID-19 pandemic, and become more costly. FHN may also incur additional costs to remedy damages caused by such disruptions, which could adversely affect FHN’s financial condition and results of operations.

Changes in interest rates due to Federal Reserve actions and market forces, mentioned above, are likely to negatively impact FHN’s net interest margin (a measure of the average profit margin applicable to

lending). In addition, “spreads” (the difference between U.S. Treasury borrowing rates and private sector borrowing rates) have widened. For new loans, wider spreads should help mitigate net interest margin compression. However, FHN will not be able to capture the widened spreads quickly for outstanding floating-rate loans: for loans pre-dating the COVID-19 crisis, spreads are fixed by the loan contracts based on pre-COVID pricing.

FHN’s customers have been adversely impacted by governmental and societal responses to COVID-19; those impacts are likely to adversely affect FHN’s noninterest income from loans and deposits as well as create downward loan migration (a reduction in loan-grading) and a corresponding increase in loan loss provision expense and reserves. In addition, loan charge-offs likely will increase over time, especially if economic disruption related to COVID-19 continues for more than a few months.

In the U.S., initial government responses to the COVID-19 pandemic were intended mainly to slow the spread of illness, regardless of the impact on economic activity. As governments relax restrictions in an effort re-invigorate the economy, it is not clear how well or how quickly the economy will recover. Substantial uncertainty regarding COVID-19, and the resulting economic damage, likely will continue until a substantial percentage of the population no longer fears contracting it.
