Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis Of Accounting | Basis of Accounting. The unaudited interim consolidated condensed financial statements of First Horizon National Corporation (“FHN”), including its subsidiaries, have been prepared in conformity with accounting principles generally accepted in the United States of America and follow general practices within the industries in which it operates. This preparation requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. These estimates and assumptions are based on information available as of the date of the financial statements and could differ from actual results. In the opinion of management, all necessary adjustments have been made for a fair presentation of financial position and results of operations for the periods presented. These adjustments are of a normal recurring nature unless otherwise disclosed in this Quarterly Report on Form 10-Q. The operating results for the interim 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, Contract Balances, Transaction Price Allocated to Remaining Performance Obligation | 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 June 30, 2020, accounts receivable related to products and services on non-interest income were $8.9 million. For the three months ended June 30, 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 June 30, 2020. Credit risk is assessed on these accounts receivable each reporting period and the amount of estimated uncollectible receivables is not material. Transaction Price Allocated to Remaining Performance Obligations. For the three and six months ended June 30, 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 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 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. 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 | 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, Purchased Credit-Deteriorated Loans, Purchased Credit-Impaired Loans, and Allowance for Loan Losses | 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: 1. Unpaid principal balance for originated assets or acquisition price for purchased assets 2. Accrued interest (see elections discussed previously) 3. Accretion or amortization of premium, discount, and net deferred fees or costs 4. Collection of cash 5. Charge-offs 6. Foreign exchange adjustments (none for FHN) 7. 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. 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. 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. 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. FHN has continued to accrue interest on loans for which payment deferrals have been extended to borrowers affected by the COVID-19 pandemic ("COVID-19 Deferrals"). Deferrals are made for durations up to six months, which is beyond FHN's normal write-off practices for accrued interest. Therefore, these interest deferrals do not qualify for FHN's election to not recognize a credit loss allowance for accrued interest. Accordingly, FHN has estimated credit losses for COVID-19 interest deferrals which is included within AIR in 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 | 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. 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: 1. Unpaid principal balance for originated assets or acquisition price for purchased assets 2. Accrued interest (see elections discussed previously) 3. Accretion or amortization of premium, discount, and net deferred fees or costs 4. Collection of cash 5. Charge-offs 6. Foreign exchange adjustments (none for FHN) 7. 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. 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 and Accounting Changes Issued But Not Currently Effective | 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 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 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 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. 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.
