Accounting Policies [Abstract]

Consolidation, Subsidiaries or Other Investments, Consolidated Entities, Policy [Policy Text Block]

BASIS OF PRESENTATION AND PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of Regions, its subsidiaries and certain VIEs. Significant intercompany balances and transactions have been eliminated. Regions considers a voting rights entity to be a subsidiary and consolidates it if Regions has a controlling financial interest in the entity. VIEs are consolidated if Regions has the power to direct the activities of the VIE that significantly impact financial performance and has the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE (i.e., Regions is the primary beneficiary). The determination of whether Regions is the primary beneficiary of a VIE is reassessed on an ongoing basis. Investments in companies which are not VIEs but in which Regions has more than minor influence over the operating and financial policies, are accounted for using the equity method of accounting. Investments in VIEs, where Regions is not the primary beneficiary of a VIE, are accounted for using either the proportional amortization method or the equity method of accounting. These investments are included in other assets. The maximum potential exposure to losses relative to investments in VIEs is generally limited to the sum of the outstanding balance, future funding commitments and any related loans to the entity. Loans to these entities are underwritten in substantially the same manner as are other loans and are generally secured. Refer to Note 2 for additional disclosures regarding Regions’ significant VIEs.

Cash and Cash Equivalents, Policy [Policy Text Block]

CASH EQUIVALENTS AND CASH FLOWS

Cash equivalents represent assets that can be converted into cash immediately. At Regions, these assets include cash and due from banks, interest-bearing deposits in other banks, and federal funds sold and securities purchased under agreements to resell. Cash flows from loans, either originated or acquired, are classified at that time according to management’s intent to either sell or hold the loan for the foreseeable future. When management’s intent is to sell the loan, the cash flows of that loan are presented as operating cash flows. When management’s intent is to hold the loan for the foreseeable future, the cash flows of that loan are presented as investing cash flows.

Repurchase Agreements, Collateral, Policy [Policy Text Block]

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 are treated as collateralized financing transactions. It is Regions’ policy to take possession of securities purchased under resell agreements either through direct delivery or a tri-party agreement.

Investment, Policy [Policy Text Block]

DEBT SECURITIES

Management determines the appropriate accounting classification of debt securities at the time of purchase, based on intent, and periodically re-evaluates such designations. Debt securities are classified as held to maturity when the Company has the intent and ability to hold the securities to maturity. Debt securities held to maturity are presented at amortized cost. Debt securities not classified as held to maturity are classified as available for sale. Debt securities available for sale are presented at estimated fair value with changes in unrealized gains and losses, net of taxes, reported as a component of accumulated other comprehensive income (loss). See the “Fair Value Measurements” section below for discussion of determining fair value.

The amortized cost of debt securities classified as held to maturity and available for sale is adjusted for amortization of premiums and accretion of discounts to maturity, or first call date when applicable, using the effective interest method. Such amortization or accretion is included in interest income on securities. Realized gains and losses are included in net securities gains (losses). The cost of securities sold is based on the specific identification method.

For debt securities available for sale, the Company reviews its securities portfolio for impairment and determines if impairment is related to credit loss or non-credit loss. In making the assessment of whether a loss is from credit or other factors, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows is less than the amortized cost basis, a credit loss exists and an allowance is created, limited by the amount that the fair value is less than the amortized cost basis.

Subsequent activity related to the credit loss component (e.g. write-offs, recoveries) is recognized as part of the allowance for credit losses on debt securities available for sale. Securities held to maturity are evaluated under the allowance for credit losses model. For securities which have an expectation of zero nonpayment of the amortized cost basis (e.g. U.S. Treasury securities or agency securities), the expected credit loss is zero. Refer to Note 3 for further detail and information on securities.

Finance, Loan and Lease Receivables, Held-for-sale, Policy [Policy Text Block]

LOANS HELD FOR SALE

Regions’ loans held for sale primarily includes commercial loans, investor real estate loans, and residential real estate mortgage loans. Loans held for sale are recorded at either estimated fair value, if the fair value option is elected, or the lower of cost or estimated fair value. Regions has elected to account for residential real estate mortgages originated with the intent to sell at fair value. Intent is established for these conforming residential real estate mortgage loans when Regions enters into an interest rate lock commitment. Gains and losses on these residential mortgage loans held for sale for which the fair value option has been elected are included in mortgage income. Management has elected the fair value option for certain commercial loans originated with the intent to sell and gains and losses on those loans are included in capital markets income. Regions also transfers certain commercial, investor real estate, and residential real estate mortgage portfolio loans that were originally recorded as held for investment to held for sale when management has the intent to sell in the near term. These loans held for sale are recorded at the lower of cost or estimated fair value. At the time of transfer, write-downs on the loans are recorded as charge-offs when credit related and non-interest expense or non-interest income (dependent on loan type) when not credit related and a new cost basis is established. Any subsequent lower of cost or market adjustment is determined on an individual loan basis. Gains and losses on the sale of non-performing commercial and investor real estate loans are included in other non-interest expense. See the “Fair Value Measurements” section below for discussion of determining estimated fair value.

Receivables, Policy [Policy Text Block]

LOANS

Regions' loans balance is comprised of commercial, investor real estate and consumer loans. Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are considered loans held for investment (or portfolio loans). Loans held for investment are carried at amortized cost (the principal amount outstanding, net of premiums, discounts, unearned income and deferred loan fees and costs). Regions elected to exclude accrued interest receivable balances from the amortized cost basis. Interest receivable is included as a separate line item on the balance sheet. Interest income on all types of loans is accrued based on the contractual interest rate and the principal amount outstanding using methods that approximate the interest method, except for those loans classified as non-accrual. Premiums and discounts on purchased loans and non-refundable loan origination and commitment fees, net of direct costs of originating or acquiring loans, are deferred and recognized over the contractual or estimated lives of the related loans as an adjustment to the loans’ constant effective yield, which is included in interest income on loans. Direct financing, sales-type and leveraged leases are included within the commercial portfolio segment. See Note 4 for further detail and information on loans and Note 13 for further detail and information on leases.

Regions determines past due or delinquency status of a loan based on contractual payment terms.

Commercial and investor real estate loans are placed on non-accrual if any of the following conditions occur: 1) collection in full of contractual principal and interest is no longer reasonably assured (even if current as to payment status), 2) a partial charge-off has occurred, unless the loan has been brought current under its contractual terms (original or restructured terms) and the full originally contracted principal and interest is considered to be fully collectible, or 3) the loan is delinquent on any principal or interest for 90 days or more unless the obligation is secured by collateral having a net realizable value (estimated fair value less costs to sell) sufficient to fully discharge the obligation and the loan is in the legal process of collection. Factors considered regarding full collection include assessment of changes in borrower’s cash flow, valuation of underlying collateral, ability and willingness of guarantors to provide credit support, and other conditions. Charge-offs on commercial and investor real estate loans are primarily based on the facts and circumstances of the individual loan and occur when available information confirms the loan is not or will not be fully collectible. Factors considered in making these determinations are the borrower’s and any guarantor’s ability and willingness to pay, the status of the account in bankruptcy court (if applicable), and collateral value. Commercial and investor real estate loan relationships of $250,000 or less are subject to charge-off or charge down to estimated fair value at 180 days past due, based on collateral value. Certain equipment finance loans are subject to charge-off at 120 days past due.

Non-accrual and charge-off decisions for consumer loans are dictated by the FFIEC's Uniform Retail Credit Classification and Account Management Policy which establishes standards for the classification and treatment of consumer loans. The charge-off process drives consumer non-accrual status. If a consumer loan secured by real estate in a first lien position (residential first mortgage or home equity) becomes 180 days past due, Regions evaluates the loan for non-accrual status and potential charge-off based on net loan to value exposure. For home equity loans and lines of credit in a second lien position, the evaluation is performed at 120 days past due. If a loan is secured by collateral having a net realizable value sufficient to fully discharge the obligation, then a partial write-down is not necessary and the loan remains on accrual status, provided it is in the process of legal collection. If a partial charge-off is necessary as a result of the evaluation, then the remaining balance is placed on non-accrual. Consumer loans not secured by real estate are generally charged-off at either 120 days past due for closed-end loans, 180 days past due for open-end loans other than credit cards or the end of the month in which the loan becomes 180 days past due for credit cards.

When loans are placed on non-accrual status, the accrual of interest, amortization of loan premium, accretion of loan discount and amortization/accretion of deferred net loan fees/costs are discontinued. When a commercial or investor real estate loan is placed on non-accrual status, uncollected interest accrued in the current year is reversed and charged to interest income. Uncollected interest accrued from prior years on commercial and investor real estate loans placed on non-accrual status in the current year is charged against the allowance for loan losses. When a consumer loan is placed on non-accrual status, all uncollected interest accrued is reversed and charged to interest income due to immateriality. Interest collections on commercial and investor real estate non-accrual loans are applied as principal reductions. Interest collections on consumer non-accrual loans are recorded using the cash basis, due to immateriality.

All loans on non-accrual status may be returned to accrual status and interest accrual resumed if all of the following conditions are met: 1) the loan is brought contractually current as to both principal and interest, 2) future payments are reasonably expected to continue being received in accordance with the terms of the loan and repayment ability can be reasonably demonstrated, and 3) the loan has been performing for at least six months.

Purchased Loans

Purchased loans are recorded at their fair value at the acquisition date. Purchased loans are evaluated and classified as either PCD, which indicates that the loan has experienced more than insignificant credit deterioration since origination, or non-PCD loans. For PCD loans, the sum of the loans' purchase price and allowance for credit losses, which is determined using the same methodology as originated loans, becomes their initial amortized cost basis. For non-PCD loans, the difference between the fair value and the par value is considered the fair value mark. The non-credit discount or premium related to PCD loans and the fair value mark on non-PCD loans is accreted or amortized into interest income over the contractual life of the loan using the effective interest method. Subsequent changes in the allowance to the PCD and non-PCD loans are recognized in the provision for credit losses.

Loans and Leases Receivable, Troubled Debt Restructuring Policy [Policy Text Block]

TDRs

TDRs are loans in which the borrower is experiencing financial difficulty at the time of restructuring, and Regions has granted a concession to the borrower. TDRs are undertaken in order to improve the likelihood of recovery on the loan and may take the form of modifications made with the stated interest rate lower than the current market rate for new debt with similar risk, other modifications to the structure of the loan that fall outside of normal underwriting policies and procedures, or in limited circumstances forgiveness of principal and/or interest. Insignificant delays in payments are not considered TDRs. TDRs can involve loans remaining on non-accrual, moving to non-accrual, or continuing on accrual status, depending on the individual facts and circumstances of the borrower. TDRs are subject to policies governing accrual/non-accrual evaluation consistent with all other loans of the same product type as discussed in the “Loans” section above.

The CAP was designed to evaluate potential consumer loan participants as early as possible in the life cycle of the troubled loan (as described in Note 5). Many of the modifications are finalized without the borrower ever reaching the applicable number of days past due, and therefore the loan may never be placed on non-accrual. Accordingly, given the positive impact of the restructuring on the likelihood of recovery of cash flows due under the modified terms, accrual status continues to be appropriate for these loans.

As provided in the CARES Act passed into law on March 27, 2020, and subsequently extended through the Consolidated Appropriations Act signed into law on December 27, 2020, certain loan modifications related to the COVID-19 pandemic beginning March 1, 2020, through the earlier of 60 days after the end of the pandemic or January 1, 2022, were eligible for relief from TDR classification. Regions elected this provision of both Acts; therefore, modified loans that met the required guidelines for relief were not considered TDRs.

Financing Receivable, Allowance for Credit Losses, Policy for Uncollectible Amounts [Policy Text Block]

ALLOWANCE

Regions adopted CECL on January 1, 2020, which replaced the incurred loss methodology to estimate the allowance with the expected loss methodology. Regions elected not to estimate an allowance on interest receivable balances because the Company has non-accrual polices in place that provide for the accrual of interest to cease on a timely basis when all contractual amounts due are not expected.

The allowance is intended to cover expected credit losses over the contractual life of loans measured at amortized cost, including unfunded commitments. Management’s measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and R&S forecasts that affect the collectability of the reported amount. For periods beyond which Regions makes or obtains such R&S forecasts, Regions reverts to historical credit loss information. Regions maintains an appropriate level of allowance that falls within an acceptable range of estimated losses, measured in accordance with GAAP. Management's determination of the appropriateness of the allowance is based on many factors, including, but not limited to, an evaluation and rating of the loan portfolio; historical loan loss experience; current economic conditions; collateral values securing loans; levels of problem loans; volume, growth, quality and composition of the loan portfolio; regulatory guidance; R&S economic forecasts; and other relevant factors. Changes in any of these factors, assumptions, or the availability of new information, could require that the allowance be adjusted in future periods, perhaps materially. Loss forecasting models are built on historical loss information and then applied to the current portfolio. Outputs from the loss forecasting models in combination with Regions' qualitative framework, and other analyses are used to inform management in its estimation of Regions' expected credit losses. Actual losses could vary, perhaps materially, from management’s estimates. The entire allowance is available to cover all charge-offs that arise from the loan portfolio.

Regions' allowance calculation is a significant estimate. Regions uses its best judgment to assess economic conditions and loss data in estimating the allowance and these estimates are subject to periodic refinement based on changes in underlying external or internal data. Therefore, assumptions and decisions driving the estimate may change as conditions change. These assumptions and estimates are detailed below.

R & S forecast period

During the two-year R&S forecast period, Regions incorporates forward-looking information by utilizing its internally developed and approved Base economic forecast. The scenario is developed by the Chief Economist and approved through a formal governance process. The Base forecast considers market forward/consensus information and is consistent with the Company's organization-wide economic outlook. When appropriate, additional scenarios, including externally created scenarios, are considered as part of the determination of the allowance.

Reversion period

Regions utilizes an exponential reversion approach that reverts to TTC rates derived from the simple average of all historical quarterly observations for PD, LGD, EAD and prepayment rates. The length of the reversion period differs by class of financing receivable.

Historical loss period

Regions does not adjust historical loss information for existing economic conditions or expectations of future economic conditions for periods that are beyond the R&S period. Regions utilizes internal historical loss information; however, there are certain loan portfolios that also benefit from the use of external or other reference data due to identified limitations with internal historical data.

Contractual life

Regions estimates expected credit losses over the contractual life of a loan. Regions defines contractual life for non-revolving loans as contractual maturity, net of estimated prepayments and excluding expected extensions, renewals and modifications unless 1) Regions has a reasonable expectation at the reporting date that it will execute a TDR with the borrower

("RETDR") or 2) extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancellable by Regions.

RETDR

Regions individually identifies commercial and investor real estate loans for inclusion as RETDRs. The identification criteria are based on internal risk ratings and time to maturity. Regions typically does not identify consumer loans as RETDRs due to the insignificant time period between initial contact with a customer regarding a loan modification and when a TDR modification is consummated.

The RETDR status extends the life of the loan past the contractual maturity and includes the allowance impact of interest rate concessions. Loans identified as RETDRs will be treated consistently from a modeling/reserving perspective as loans identified as TDRs.

Contractual term extensions (borrower versus lender option to renew)

Regions' consumer loan contracts do not permit automatic extensions or unilateral customer extensions, and Regions retains the right to approve or deny any extension requested from the borrower. As a result, extensions and renewal options are not included in the life of consumer loans for the purposes of calculating the allowance. Similarly, Regions does not include extension and renewal options in the life of commercial loans for the purposes of calculating the allowance, unless it is a RETDR. Most commercial products do not offer borrowers a unilateral right to renew or extend.

Contractual life of credit card receivables

Regions estimates the life of credit card receivables based on the amount and timing of payments expected to be collected. Regions' credit card allowance estimate only considers the amount of debt outstanding at the reporting date (the current position) because undrawn balances are unconditionally cancellable. Regions classifies credit card accounts into one of three payment patterns: dormant, transacting or revolving. The dormant accounts are idle, carry no balance, and do not contribute to the allowance. The transacting account holders tend to pay the entire balance due every month and are, therefore, subject to practically no interest charges. For transactor accounts, the current position balance is expected to be paid off in one quarter. The revolving accounts tend to be subject to interest charges, and their current position balance liquidates over time. Regions' credit card portfolio is comprised primarily of revolvers.

Collateral-dependent loans

Regions' collateral-dependent consumer loans are loans secured by collateral (primarily real estate) that meet the partial charge-down requirements disclosed within this section. Regions evaluates significant commercial and investor real estate loans that are in financial difficulty and secured by collateral to determine if they are collateral dependent.

For any collateral-dependent loans that meet Regions' specific allowance criteria (see below), Regions will calculate the allowance based on the fair value of collateral methodology. For collateral-dependent consumer, commercial and investor real estate loans that do not meet Regions' specific allowance criteria (as described below), Regions considers the value of the collateral through the LGD component of the loss model based on collateral type.

Credit enhancements

Regions' estimate of credit losses reflects how credit enhancements, other than those that are freestanding contracts, mitigate expected credit losses on financial assets. In the event that a credit enhancement arrangement is considered to be a freestanding contract, Regions excludes the credit enhancement from the related loan when estimating expected credit losses.

Unfunded commitments and other off-balance sheet items

Regions records a liability or allowance for credit losses for the unfunded portion of a loan commitment in the event that the issuer does not have the unconditional right to cancel the commitment. For an unfunded commitment to be considered unconditionally cancellable, Regions must be able to, at any time, with or without cause, refuse to extend credit. The liability is measured over the full contractual period for which Regions is exposed to credit risk through a current obligation to extend credit. In determining the liability, management considers the likelihood that funding will occur, and if funded, the related expected credit losses under the allowance model.

Regions' off-balance sheet unfunded commitments in the form of home equity lines, standby letters of credit, commercial letters of credit and commercial revolving products that are deemed to be conditionally cancellable will include unfunded balances within the allowance estimate. Future advances from certain unfunded commitments and other revolving products where Regions does have the unconditional right to cancel these agreements will not be included.

CALCULATION OF ALLOWANCE FOR CREDIT LOSSES

Pooled allowances

The allowance is measured on a collective (pool) basis when similar risk characteristics exist. Segmentation variables for commercial and investor real estate segments include product, loan size, collateral type, risk rating and term. Segmentation

variables considered for consumer segments include product, FICO, LTV, age, TDR status, etc. The allowance is estimated for most portfolios and classes using econometric models to estimate expected credit losses. In general, discounted cash flow models are not used for the purpose of estimating expected losses for the purpose of the ACL. Most of the econometric models include PD, LGD, and EAD components. Less complex estimation methods are used for smaller loan portfolios.

Specific allowances

Due to their size, complexity and individualized risk characteristics and monitoring, the allowance for significant non-accrual commercial and investor real estate loans (including TDRs) and unfunded commitments is measured on an individual basis. Loans evaluated individually are not included in the collective evaluation. Regions generally measures the allowance for these loans based on the present value of estimated cash flows, considering all facts and circumstances specific to the borrower and market and economic conditions. The allowance measurement for collateral-dependent loans that meet the individually evaluated threshold is based on the fair value of collateral methodology.

TDRs and RETDRs

Loans identified as TDRs and RETDRs are included in their respective loan pools (if they do not qualify for specific evaluation) and losses are determined by allowance models. The effect of the interest rate concession on these loans is considered through a post-model adjustment.

Qualitative framework

While quantitative allowance methodologies strive to reflect all risk factors, any estimate involves assumptions and uncertainties resulting in some level of imprecision. Imprecision exists in the estimation process due to the inherent time lag between obtaining information, performing the calculation, as well as variations between estimates and actual outcomes. Regions adjusts the allowance considering quantitative and qualitative factors which may not be directly measured in the modeled calculations. Regions' qualitative framework provides for specific quantitatively supported model adjustments and general imprecision adjustments. Specific model adjustments capture highly specific issues or events that Regions believes are not adequately captured in model outcomes. General imprecision adjustments address other sources of imprecision that are not specifically identifiable or quantifiable to a particular loan portfolio and have not been captured by the model or by a specific model adjustment. Regions considers general imprecision in three dimensions; economic forecast imprecision, model imprecision, and process imprecision.

Refer to Note 5 for further discussion regarding the calculation of the allowance for credit losses.

Lessee, Leases [Policy Text Block]

LESSEES

Regions' lease portfolio is primarily composed of property leases that are classified as either operating or finance leases with the majority classified as operating leases. Property leases, which primarily include office locations and retail branches, typically have original lease terms ranging from 1 year to 20 years, some of which may also include an option to extend the lease beyond the original lease term. In some circumstances, Regions may also have an option to terminate the lease early with advance notice. Regions includes renewal and termination options within the lease term if deemed reasonably certain of exercise. As most leases do not state an implicit rate, Regions utilizes the incremental borrowing rate based on information available at the lease commencement date to determine the present value of lease payments. Leases with a term of 12 months or less are not recorded on the balance sheet. Regions continues to recognize lease payments as an expense over the lease term as appropriate.

Operating leases vary in term and, from time to time, include incentives and/or rent escalations. Examples of incentives include periods of “free” rent and leasehold improvement incentives. Regions recognizes incentives and escalations on a straight-line basis over the lease term as a reduction of or increase to rent expense, as applicable, within net occupancy expense in the consolidated statements of income. See Note 13 "Leases" for additional information.

Lessor, Leases [Policy Text Block]

LESSORS

Regions engages in both direct financing and sales-type leasing. Regions also has a portfolio of leveraged leases. These arrangements provide equipment financing for leased assets, such as vehicles and aircraft. At the commencement date, Regions (lessor) enters into an agreement with the customer (lessee) to lease the underlying equipment for a specified lease term. The lease agreements may provide customers the option to terminate the lease by buying the equipment at fair market value at the time of termination or at the end of the lease term. Regions' equipment finance asset management group performs due diligence procedures on the lease residual and overall equipment values as part of the origination process. Regions performs lease residual value reviews on an ongoing basis. In order to manage the residual value risk inherent in some of its direct financing leases, Regions purchases residual value insurance from an independent third party.

Sales-type, direct financing, and leveraged leases are recorded within loans on the consolidated balance sheet. The net investment in direct financing leases is the sum of all minimum lease payments and estimated residual values, less unearned income. Unearned income is recognized over the terms of the leases to produce a constant effective yield. The net investment in leveraged leases is the sum of all lease payments (less non-recourse debt payments) and estimated residual values, less unearned income. Income from leveraged leases is recognized over the term of the leases based on the unrecovered equity investment. See Note 13 "Leases" for additional information.

Other Earning Assets [Policy Text Block]

OTHER EARNING ASSETSOther earning assets consist of investments in FRB stock, FHLB stock, marketable equity securities and other miscellaneous earning assets. Ownership of FRB and FHLB stock is a requirement for all banks seeking membership into and access to the services provided by these banking systems. These shares are accounted for at amortized cost, which approximates fair value. Marketable equity securities are recorded at fair value with changes in fair value reported in net income. See Note 7 for additional information.

Property, Plant and Equipment, Policy [Policy Text Block]

PREMISES AND EQUIPMENT

Premises and equipment are stated at cost, less accumulated depreciation and amortization, as applicable. Land is carried at cost. Depreciation expense is computed using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are amortized using the straight-line method over the estimated useful lives of the improvements (or the terms of the leases, if shorter). Generally, premises and leasehold improvements are depreciated or amortized over 7-40 years. Furniture and equipment are generally depreciated or amortized over 3-10 years. Premises and equipment are evaluated for impairment at least annually, or more often if events or circumstances indicate that the carrying value of the asset may not be recoverable. Maintenance and repairs are charged to non-interest expense in the consolidated statements of income. Improvements that either add functionality or extend the useful life of the asset are capitalized to the carrying value and depreciated. See Note 8 for detail of premises and equipment.

Goodwill and Intangible Assets, Policy [Policy Text Block]

INTANGIBLE ASSETS

Intangible assets include goodwill, which is the excess of cost over the fair value of net assets of acquired businesses, and other identifiable intangible assets. Other identifiable intangible assets primarily include relationship assets, agency commercial real estate licenses, and amounts capitalized related to the value of PCCR. Other identifiable intangibles assets are primarily amortized over their expected useful lives while agency commercial real estate licenses are non-amortizing.

The Company’s goodwill is tested for impairment on an annual basis in the fourth quarter, or more often if events or circumstances indicate that there may be impairment. Regions assesses the following indicators of goodwill impairment for each reporting period:

•Recent operating performance,

•Changes in market capitalization,

•Regulatory actions and assessments,

•Changes in the business climate (including legislation, legal factors and competition),

•Company-specific factors (including changes in key personnel, asset impairments, and business dispositions), and

•Trends in the banking industry.

Adverse changes in the economic environment, declining operations, or other factors could result in a decline in the implied estimated fair value of goodwill. Accounting guidance permits the Company to first assess qualitative factors to determine if it is more likely than not that the fair value of a reporting unit exceeds its carrying value. If, based on the weight of the evidence, the Company determines it is more likely than not that the fair value exceeds book value, then an impairment test is not necessary. If the Company elects to bypass the qualitative assessment, or concludes that it is more likely than not that the fair value is less than the carrying value, a goodwill impairment test is performed. The Company compares the estimated fair value of a reporting unit with its carrying amount, including goodwill. If the estimated fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired. If the carrying amount of a reporting unit exceeds its estimated fair value, an impairment loss is recognized in non-interest expense in an amount equal to that excess.

For purposes of performing the qualitative assessment, Regions evaluates events and circumstances which may include, but are not limited to, events and circumstances since the last impairment analysis, recent operating performance including reporting unit performance, changes in market capitalization, regulatory actions and assessments, changes in the business climate, company-specific factors, and trends in the banking industry to determine if it is more likely than not that the fair value of a reporting unit exceeds its carrying amount.

For purposes of performing the goodwill impairment test, if applicable, Regions uses both income and market approaches to value its reporting units. The income approach, which is the primary valuation approach, consists of discounting projected long-term future cash flows, which are derived from internal forecasts and economic expectations for the respective reporting

units. The significant inputs to the income approach include expected future cash flows, the long-term target equity ratios, and the discount rate.

Other identifiable intangible assets are reviewed at least annually (usually in the fourth quarter) for events or circumstances that could impact the recoverability of the intangible asset. These events could include loss of core deposits, loss of relationships, significant losses of credit card or other types of acquired customer accounts and/or balances, increased competition, or adverse changes in the economy. To the extent other identifiable intangible assets are deemed unrecoverable, impairment losses are recorded in non-interest expense and reduce the carrying amount of the asset.

Refer to Note 9 for further detail and discussion of the results of the goodwill and other identifiable intangibles impairment tests.

Transfers and Servicing of Financial Assets, Policy [Policy Text Block]

ACCOUNTING FOR TRANSFERS AND SERVICING OF FINANCIAL ASSETS

Regions accounts for transfers of financial assets as sales when control over the transferred assets is surrendered. Control is generally considered to have been surrendered when 1) the transferred assets are legally isolated from the Company or its consolidated affiliates, even in bankruptcy or other receivership, 2) the transferee has the right to pledge or exchange the assets with no conditions that constrain the transferee and provide more than a trivial benefit to the Company, and 3) the Company does not maintain the obligation or unilateral ability to reclaim or repurchase the assets. If these sale criteria are met, the transferred assets are removed from the Company’s balance sheet and a gain or loss on sale is recognized. If not met, the transfer is recorded as a secured borrowing, and the assets remain on the Company’s balance sheet, the proceeds from the transaction are recognized as a liability, and gain or loss on sale is deferred until the sale criterion are achieved.

Regions has elected to account for its residential MSRs using the fair value measurement method. Under the fair value measurement method, residential MSRs are measured at estimated fair value each period with changes in fair value recorded as a component of mortgage income. The fair value of residential MSRs is calculated using various assumptions including future cash flows, market discount rates, expected prepayment rates, servicing costs and other factors. A significant change in prepayments of residential mortgages in the servicing portfolio could result in significant valuation adjustments, thus creating potential volatility in the carrying amount of residential MSRs. The valuation method relies on an OAS to consider prepayment risk and equate the asset's discounted cash flows to its market price. See the “Fair Value Measurements” section below for additional discussion regarding determination of fair value.

Regions is a DUS lender. The DUS program provides liquidity to the multi-family housing market. Regions' related commercial MSRs are recorded in other assets at the lower of cost or estimated fair value and are amortized in proportion to, and over the estimated period that net servicing income is expected to be received based on projections of the amount and timing of estimated future net cash flows. The amount and timing of estimated future net cash flows are updated based on actual results and updated projections. Regions periodically evaluates these commercial MSRs for impairment. Regions has a one-third loss share guarantee associated with the majority of the DUS servicing portfolio. The other two-thirds loss share guarantee is retained by Fannie Mae. The estimated fair value of the loss share guarantee is recorded in other liabilities.

Refer to Note 6 for further information on servicing of financial assets.

Finance, Loan and Lease Receivables, Held for Investments, Foreclosed Assets Policy [Policy Text Block]

FORECLOSED PROPERTY AND OTHER REAL ESTATE

Other real estate and certain other assets acquired in satisfaction of indebtedness (“foreclosure”) are carried in other assets at the lower of the recorded investment in the loan or estimated fair value less estimated costs to sell the property. At the date of transfer from the loan portfolio, if the recorded investment in the loan exceeds the property’s estimated fair value less estimated costs to sell, a write-down is recorded against the allowance. Regions allows a period of up to 60 days after the date of transfer to record finalized write-downs as charge-offs against the allowance in order to properly accumulate all related invoices and updated valuation information, if necessary. Subsequent to transfer, Regions obtains valuations from professional valuation experts and/or third party appraisers on at least an annual basis. See the “Fair Value Measurements” section below for additional discussion regarding determination of fair value. Subsequent to transfer and the additional 60 days, any further write-downs are recorded as other non-interest expense. Gain or loss on the sale of foreclosed property and other real estate is included in other non-interest expense.

From time to time, assets classified as premises and equipment are transferred to held for sale for various reasons. These assets are carried in other assets at the lower of the recorded investment in the asset or estimated fair value less estimated cost to sell based upon the property’s appraised value at the date of transfer. Any adjustments to property held for sale are recorded as other non-interest expense.

Equity Method Investments Issuances, Policy [Policy Text Block]

OTHER INVESTMENT ASSETS

Regions has investments of approximately $223 million and $207 million at December 31, 2022 and 2021, respectively, that are recognized in other assets and accounted for using either the equity method of accounting or the measurement alternative to fair value for equity investments without a readily determinable fair value.

Equity method investments consist primarily of investments in SBICs and private equity funds. Under the equity method of accounting, Regions records its proportionate share of the profits or losses of the investment entity as an adjustment to the carrying value of the investment and as a component of other non-interest income. Dividends and distributions received or receivable from these investments are recorded as reductions to the carrying value of the investments. The net balances of equity method investments were approximately $153 million and $136 million at December 31, 2022 and 2021, respectively.

Equity investments that do not meet the criteria to be accounted for under the equity method and do not have a readily determinable fair value are accounted for at cost under the measurement alternative to fair value with adjustments for impairment and observable price changes as applicable. Dividends received or receivable and observable price changes from these investments are included as components of other non-interest income. These investments consist primarily of investments in strategic partners and certain CRA projects. The carrying amounts of these investments were $70 million and $71 million at December 31, 2022 and 2021, respectively.

Derivatives, Policy [Policy Text Block]

DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES

The Company enters into derivative financial instruments to manage interest rate risk, facilitate asset/liability management strategies and manage other exposures. These instruments primarily include interest rate swaps, options on interest rate swaps, options including interest rate caps and floors, Eurodollar futures, forward rate contracts and forward sale commitments. All derivative financial instruments are recognized as other assets or other liabilities, as applicable, at estimated fair value. Regions enters into master netting agreements with counterparties and/or requires collateral to cover exposures. In at least some cases, counterparties post collateral at a zero threshold regardless of credit rating. The majority of interest rate derivatives traded by Regions with dealing counterparties are subject to mandatory clearing through a central clearinghouse. The variation margin payments made for derivatives cleared through a central clearinghouse are legally characterized as settlements of the derivatives. The counterparty risk for cleared trades effectively moves from the executing broker to the clearinghouse allowing Regions to benefit from the risk mitigation controls in place at the respective clearinghouse.

Interest rate swaps are agreements to exchange interest payments based upon notional amounts. Interest rate swaps subject Regions to market risk associated with changes in interest rates, changes in interest rate volatility, as well as the credit risk that the counterparty will fail to perform. Option contracts involve rights to buy or sell financial instruments on a specified date or over a period at a specified price. These rights do not have to be exercised. Some option contracts such as interest rate floors, involve the exchange of cash based on changes in specified indices. Interest rate floors are contracts to hedge interest rate declines based on a notional amount, generally associated with a principal balance at risk. Interest rate floors subject Regions to market risk associated with changes in interest rates, changes in interest rate volatility, as well as the credit risk that the counterparty will fail to perform. Forward rate contracts are commitments to buy or sell financial instruments at a future date at a specified price or yield. Regions primarily enters into forward rate contracts on marketable instruments, which expose Regions to market risk associated with changes in the value of the underlying financial instrument, as well as the credit risk that the counterparty will fail to perform. Eurodollar futures are futures contracts on Eurodollar deposits. Eurodollar futures subject Regions to market risk associated with changes in interest rates. Because futures contracts are cash settled daily through a margining process in an exchange, there is minimal credit risk associated with Eurodollar futures. Forward sale commitments are sales of securities at a specified price at a future date. Forward sale commitments subject Regions to market risk associated with changes in market value, as well as the credit risk that the counterparty will fail to perform.

The Company elects to account for certain derivative financial instruments as accounting hedges which, based on the exposure being hedged, are either fair value or cash flow hedges.

Fair value hedge relationships mitigate exposure to the change in fair value of the hedged risk in an asset, liability or firm commitment. Certain fair value hedges may be entered into using the portfolio layer method, which allows the Company to hedge the interest rate risk of non-prepayable and prepayable financial assets by designating as the hedged item a stated amount of a closed portfolio that is expected to be outstanding for the designated hedge period(s). Under the fair value hedging model, gains or losses attributable to the change in fair value of the derivative instrument, as well as the gains and losses attributable to the change in fair value of the hedged item, are recognized in interest income or interest expense in the same income statement line item with the hedged item in the period in which the change in fair value occurs. To the extent the changes in fair value of the derivative do not offset the changes in fair value of the hedged item, the difference is recognized. The corresponding adjustment to the hedged asset or liability is included in the basis of the hedged item, while the corresponding change in the fair value of the derivative instrument is recorded as an adjustment to other assets or other liabilities, as applicable.

Cash flow hedge relationships mitigate exposure to the variability of future cash flows or other forecasted transactions. For cash flow hedge relationships, the entire change in the fair value of the hedging instrument would be recorded in accumulated other comprehensive income (loss) except for amounts excluded from the assessment of hedge effectiveness. Amounts recorded in accumulated other comprehensive income (loss) are recognized in earnings in the same income statement line item where the earnings effect of the hedged item is presented in the period or periods during which the hedged item impacts earnings.

The Company formally documents all hedging relationships, as well as its risk management objective and strategy for entering into various hedge transactions. The Company performs periodic qualitative and quantitative assessments to determine whether the hedging relationship has been highly effective in offsetting changes in fair values or cash flows of hedged items and whether the relationship is expected to continue to be highly effective in the future.

If a hedge relationship is de-designated or if hedge accounting is discontinued because the hedged item no longer exists, or does not meet the definition of a firm commitment, or because it is probable that the forecasted transaction will not occur, the derivative will continue to be recorded as an other asset or other liability in the consolidated balance sheets at its estimated fair value, with changes in fair value recognized in other non-interest expense. Any asset or liability that was recorded pursuant to recognition of the firm commitment is removed from the consolidated balance sheets and recognized in other non-interest expense. Gains and losses that were unrecognized and aggregated in accumulated other comprehensive income (loss) pursuant to the hedge of a forecasted transaction are recognized immediately in other non-interest expense.

Derivative contracts for which the Company has not elected to apply hedge accounting are classified as other assets or liabilities with gains and losses related to the change in fair value recognized in capital markets income or mortgage income, as applicable, in the statements of income during the period. These positions, as well as non-derivative instruments, are used to mitigate economic and accounting volatility related to customer derivative transactions, the mortgage pipeline and the fair value of residential MSRs.

Regions enters into interest rate lock commitments, which are commitments to originate mortgage loans whereby the interest rate on the loan is determined prior to funding and the customers have locked into that interest rate. Accordingly, such commitments are recorded at estimated fair value with changes in fair value recorded in mortgage income or capital markets income, as applicable. Regions also has corresponding forward sale commitments related to these interest rate lock commitments, which are recorded at estimated fair value with changes in fair value recorded in mortgage income or capital markets income, as applicable. See the “Fair Value Measurements” section below for additional information related to the valuation of interest rate lock commitments.

Regions enters into various derivative agreements with customers desiring protection from possible future market fluctuations. Regions manages the market risk associated with these derivative agreements. The contracts in this portfolio for which the Company has elected not to apply hedge accounting are marked-to-market through capital markets income and included in other assets and other liabilities.

Concurrent with the election to use fair value measurement for residential MSRs, Regions began using various derivative instruments to mitigate the impact of changes in the fair value of residential MSRs in the statements of income. This effort may involve the use of various derivative instruments, including, but not limited to, forwards, futures, swaps, options, and TBA's designed as derivative instruments. These derivatives are carried at estimated fair value, with changes in fair value reported in mortgage income.

Refer to Note 20 for further discussion and details of derivative financial instruments and hedging activities.

Income Tax, Policy [Policy Text Block]

INCOME TAXES

The Company accounts for income taxes using the asset and liability method. Accrued income taxes and the net balance of deferred tax assets and liabilities are reported in other assets or other liabilities in the consolidated balance sheets, as appropriate. The Company reflects the expected amount of income tax to be paid or refunded during the year as current income tax expense or benefit, as applicable. Deferred tax assets and liabilities are determined based on differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that the Company expects will apply at the time when the deferred tax assets and liabilities are expected to be realized. Deferred tax assets are also recorded for any tax attributes, such as tax credit and net operating loss carryforwards. The Company determines the realization of deferred tax assets by considering all positive and negative evidence available, and a valuation allowance is recorded for any deferred tax assets that are not more-likely-than-not to be realized. Any effect of a change in federal and state tax rates on deferred tax assets and liabilities is recognized in income tax expense in the period that includes the enactment date.

The Company will evaluate and recognize income tax benefits related to any uncertain tax positions using the recognition and cumulative-probability measurement thresholds. If the Company does not believe that it is more likely than not that an uncertain tax position will be sustained, the Company records a liability for the uncertain tax position. If a tax benefit is more-likely-than-not of being sustained based on the technical merits, the Company utilizes the cumulative probability measurement and records an income tax benefit equivalent to the largest amount of tax benefit that is greater than 50 percent likely to be realized upon ultimate settlement with a taxing authority. The Company recognizes interest and penalties related to unrecognized tax benefits within current income tax expense.

The Company applies the proportional amortization method in accounting for its qualified affordable housing investments. This method recognizes the amortized cost of the investment as a component of income tax expense.

The deferral method of accounting is used for investments that generate investment tax credits. Under this method, the investment tax credits are recognized as a reduction of the related asset.

Refer to Note 19 for further discussion regarding income taxes.

Treasury Stock and Share Repurchases [Policy Text Block]

TREASURY STOCK AND SHARE REPURCHASES

The purchase of the Company’s common stock is recorded at cost. At the date of repurchase, shareholders' equity is reduced by the repurchase price. Upon retirement, or upon purchase for constructive retirement, treasury stock would be reduced by the cost of such stock with the excess of repurchase price over par or stated value recorded in additional paid-in capital. If the Company subsequently reissues treasury shares, treasury stock is reduced by the cost of such stock with differences recorded in additional paid-in capital or retained earnings, as applicable.

Pursuant to recent share repurchase programs, shares repurchased were immediately retired, and therefore were not included in treasury stock. The Company's policy related to these share repurchases is to reduce its common stock based on the par value of the shares repurchased and to reduce its additional paid-in capital for the excess of the repurchase price over the par value.

Compensation Related Costs, Policy [Policy Text Block]

SHARE-BASED PAYMENTS

Regions sponsors stock plans which most commonly include restricted stock (i.e., unvested common stock) units, restricted stock awards and performance stock units. The Company accounts for share-based payments under the fair value recognition provisions whereby compensation cost is measured based on the estimated fair value of the award at the grant date and is recognized in the consolidated financial statements on a straight-line basis over the requisite service period for service-based awards. The fair value of restricted stock units, restricted stock awards or performance stock units is determined based on the closing price of Regions common stock on the date of grant. Historical data is also used to estimate future employee attrition, which is considered in calculating estimated forfeitures. Estimated forfeitures are adjusted when actual forfeitures differ from estimates, resulting in the recognition of compensation cost only for awards that vest. The effect of a change in estimated forfeitures is recognized through a cumulative catch-up adjustment that is included in salaries and employee benefits expense in the period of the change in estimate. As compensation cost is recognized, a deferred tax asset is recorded that represents an estimate of the future tax deduction from exercise or release of restrictions. At the time the share-based awards are exercised, cancelled, have expired, or restrictions are released, the Company may be required to recognize an adjustment to tax expense depending on the market price of the Company’s common stock. Prior to 2021, Regions' sponsored plans also included stock options. Refer to Note 1 "Summary of Significant Accounting Policies" and Note 16 "Share-Based Payments" of the Annual Report on Form 10-K for the year ended December 31, 2021, for additional information regarding the accounting and reporting policies related to stock options.

See Note 16 for further discussion and details of share-based payments.

Pension and Other Postretirement Plans, Pensions, Policy [Policy Text Block]

EMPLOYEE BENEFIT PLANS

Regions uses an expected long-term rate of return applied to the fair market value of assets as of the beginning of the year and the expected cash flows during the year for calculating the expected investment return on all pension plan assets. At a minimum, amortization of the net gain or loss included in accumulated other comprehensive income resulting from experience different from that assumed and from changes in assumptions is included as a component of net periodic benefit cost if, as of the beginning of the year, that net gain or loss exceeds 10 percent of the greater of the projected benefit obligation or the market value of plan assets. If amortization is required, the minimum amortization is that excess divided by the average remaining service period of active participating employees expected to receive benefits under the plans. Regions records the service cost component of net periodic pension and postretirement benefit cost in salaries and employee benefits expense. The other components of net periodic pension and postretirement benefit cost are recorded in other non-interest expense. Regions uses a third-party actuary to compute the remaining service period of active participating employees. This period reflects expected turnover, pre-retirement mortality, and other applicable employee demographics.

See Note 17 for further discussion and details of employee benefit plans.

Revenue Recognition, Policy [Policy Text Block]

REVENUE RECOGNITION

The Company records revenue when control of the promised products or services is transferred to the customer, in an amount that reflects the consideration Regions expects to be entitled to receive in exchange for those products or services. Related to contract costs, Regions expenses sales commissions and any related contract costs when incurred because the amortization period would be one year or less. Related to remaining performance obligations, Regions does not disclose the value of unsatisfied performance obligations for 1) contracts with an original expected length of one year or less and 2) contracts for which revenue is recognized at the amount to which Regions has the right to invoice for services performed.

Interest Income

The largest source of revenue for Regions is interest income. Interest income is recognized using the interest method driven by nondiscretionary formulas based on written contracts, such as loan agreements or securities contracts.

Service Charges on Deposit Accounts

Service charges on deposit accounts include overdraft fees and other service charges. When a depositor presents an item for payment in excess of available funds, overdraft fees are earned when Regions, at its discretion, provides the necessary funds to complete the transaction. Prior to mid-2022, service charges on deposit accounts also included non-sufficient fund fees, which were earned when a depositor presented an item for payment in excess of available funds and an item was returned unpaid.

Regions generates other service charges by providing depositors proper safeguard and remittance of funds as well as by providing optional services for depositors, such as check imaging or treasury management, that are performed upon the depositor’s request. Charges for the proper safeguard and remittance of funds are recognized monthly, as the customer retains funds in the account. Regions recognizes revenue for other optional services when the customer uses the selected service to execute a transaction (e.g., execute an ACH wire).

Card and ATM Fees

Card and ATM fees include the combined amounts of credit card, debit card, and ATM related revenue. The majority of the fees are card interchange where Regions earns a fee for remitting cardholder funds (or extends credit) via a third party network to merchants. Regions satisfies performance obligations for each transaction when the card is used and the funds are remitted. The network establishes interchange fees that the merchant remits to Regions for each transaction, and Regions incurs costs from the network for facilitating the interchange with the merchant. Due to its inability to establish prices and direct activities of the related processing network’s service, Regions is deemed the agent in this arrangement and records interchange revenues net of related costs. Regions also pays consideration to certain commercial card holders based on interchange fees and contractual volume. These costs are recognized as a reduction to interchange income.

Card and ATM fees also include ATM fee income generated from allowing a Regions cardholder to withdraw funds from a non-Regions ATM and from allowing a non-Regions cardholder to withdraw funds from a Regions ATM. Regions satisfies performance obligations for each transaction when the withdrawal is processed. Regions does not direct activities of the related processing network’s service and recognizes revenue on a net basis as the agent in each transaction.

Investment Management and Trust Fee Income

Investment management and trust fee income represents revenue generated from asset management services provided to individuals, businesses, and institutions. Regions has a fiduciary responsibility to the beneficiary of the trust to perform agreed upon services which can include investing the assets, periodic reporting to the beneficiaries, and providing tax information regarding the trust. In exchange for these trust and custodial services, Regions collects fee income from beneficiaries as contractually determined via fee schedules. Regions’ performance obligations to customers are primarily satisfied over time as the services are performed and provided to the customer.

Mortgage Income

Mortgage income is recognized when earned or as each transaction occurs through the origination and servicing of residential mortgage loans for long-term investors and sales of residential mortgage loans in the secondary market. Mortgage income also includes any fair value adjustments for mortgage loans Regions has elected to measure under the fair value option and fair value adjustments related to mortgage servicing rights.

Capital Markets Income

Regions generates capital markets fee revenue through capital raising activities which include revenue streams such as securities underwriting and placement, loan syndication and placement, as well as foreign exchange, derivatives, merger and acquisition and other advisory services. For those revenue streams, revenue is primarily recognized at a point in time which coincides with the satisfaction of a single performance obligation, typically the transaction closing.

Securities underwriting and placement fees involve the issuing and distribution of securities for an underwriting fee from customers. The underwriting fee is a single performance obligation which is satisfied at the time that the transaction is closed, and the amount of the fee is either a fixed or variable percentage based on the deal value which is determinable at the time of deal closing.

Regions generates revenue from affordable housing investments through the syndication of investment funds to third parties. Regions transfers the primary benefits of the investment to the customer and recognizes syndication revenue on the closing date of the transaction.

Bank-Owned Life Insurance

Bank-owned life insurance income primarily represents income earned from the appreciation of the cash surrender value of insurance contracts held and the proceeds of insurance benefits. Regions recognizes revenue each period in the amount of the appreciation of the cash surrender value of the insurance policies. Revenue from the proceeds of insurance benefits is recognized at the time a claim is confirmed.

Commercial Credit Fee Income

Commercial credit fee income includes letters of credit fees and unused commercial commitment fees. Regions recognizes revenue for letters of credit fees and unused commercial commitment fees over time.

Investment Services Fee Income

Investment services fee income represents income earned from investment advisory services. Through the use of third party carriers, Regions provides its customers with access to investment products that meet customers’ financial needs and investment objectives. Upon selection of an investment product, the customer enters into a policy with the carrier. Regions’ performance obligation is satisfied by fulfilling its responsibility to place customers in investment vehicles for which Regions earns commissions from the carrier based on agreed-upon fee percentages. In addition, Regions has a contractual relationship with a third party broker dealer to provide full service brokerage and investment advisory activities. As the principal in the arrangement, Regions recognizes the investment services commissions on a gross basis.

Securities Gains (Losses), Net

Net securities gains or losses result from Regions’ asset/liability management process. Gains or losses on the sale of securities are recognized as each sales transaction occurs with the cost of securities sold based on the specific identification method.

Market Value Adjustments on Employee Benefit Assets

Regions holds assets for certain employee benefit assets, both defined and other. Those assets are recorded at estimated fair value and the market value variations are recognized each period.

Other Miscellaneous Income

Other miscellaneous income includes miscellaneous revenue from affordable housing, income from SBIC investments, valuation adjustments to equity investments, commercial loan and leasing related income, fees from safe deposit boxes, check fees, and other miscellaneous income including unusual gains. Regions recognizes the related fee or gain in a manner that reflects the timing of when transactions occur or as services are provided.

Earnings Per Share, Policy [Policy Text Block]

PER SHARE AMOUNTSEarnings per common share is calculated by dividing net income available to common shareholders by the weighted-average number of common shares outstanding during the period. Diluted earnings per common share is calculated by dividing net income available to common shareholders by the weighted-average number of common shares outstanding during the period, plus the effect of restricted and performance stock awards, and in periods prior to 2021, outstanding stock options, if dilutive. Refer to Note 15 for additional information

Fair Value of Financial Instruments, Policy [Policy Text Block]

FAIR VALUE MEASUREMENTS

Fair value guidance establishes a framework for using fair value to measure assets and liabilities and defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) as opposed to the price that would be paid to acquire the asset or received to assume the liability (an entry price). A fair value measure should reflect the assumptions that market participants would use in pricing the asset or liability, including the assumptions about the risk inherent in a particular valuation technique, the effect of a restriction on the sale or use of an asset and the risk of nonperformance. Required disclosures include stratification of balance sheet amounts measured at fair value based on inputs the Company uses to derive fair value measurements. These strata include:

•Level 1 valuations, where the valuation is based on quoted market prices for identical assets or liabilities traded in active markets (which include exchanges and over-the-counter markets with sufficient volume),

•Level 2 valuations, where the valuation is based on quoted market prices for similar instruments traded 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, and

•Level 3 valuations, where the valuation is generated from model-based techniques that use significant assumptions not observable in the market, but observable based on Company-specific data. These unobservable assumptions reflect the Company’s own estimates for assumptions that market participants would use in pricing the asset or liability. Valuation techniques typically include option pricing models, discounted cash flow models and similar techniques, but may also include the use of market prices of assets or liabilities that are not directly comparable to the subject asset or liability.

ITEMS MEASURED AT FAIR VALUE ON A RECURRING BASIS

Debt securities available for sale, certain mortgage loans held for sale, marketable equity securities, residential MSRs, derivative assets and derivative liabilities are recorded at fair value on a recurring basis. Below is a description of valuation methodologies for these assets and liabilities.

Debt securities available for sale consist of U.S. Treasuries, obligations of states and political subdivisions, mortgage-backed securities (including agency securities), and other debt securities.

•U.S. Treasuries are valued based on quoted market prices of identical assets on active exchanges. Pricing received for U.S. Treasuries from third-party services is based on a market approach using dealer quotes from multiple active market makers and real-time trading systems. These valuations are Level 1 measurements.

•Mortgage-backed securities are valued primarily using data from third-party pricing services for similar securities as applicable. Pricing from these third-party services is generally based on a market approach using observable inputs such as benchmark yields, reported trades, broker/dealer quotes, benchmark securities, TBA prices, issuer spreads, bids and offers, monthly payment information, and collateral performance, as applicable. These valuations are Level 2 measurements. Where such comparable data is not available, the Company develops valuations based on assumptions that are not readily observable in the market place; these valuations are Level 3 measurements.

•Obligations of states and political subdivisions are generally based on data from third-party pricing services. The valuations are based on a market approach using observable inputs such as benchmark yields, relevant trade data, material event notices and new issue data. These valuations are Level 2 measurements.

•Other debt securities are valued based on Level 1, 2 and 3 measurements, depending on pricing methodology selected and are valued primarily using data from third-party pricing services. Pricing from these third-party services is generally based on a market approach using observable inputs such as benchmark yields, reported trades, broker/dealer quotes, issuer spreads, benchmark securities, bids and offers, and TRACE reported trades.

The majority of Regions' debt securities available for sale are valued using third-party pricing services. To validate pricing related to liquid investment securities, which represent the vast majority of the available for sale portfolio (e.g., mortgage-backed securities), Regions compares price changes received from the third-party pricing service to overall changes in market factors in order to validate the pricing received. To validate pricing received on less liquid investment securities in the available for sale portfolio, Regions receives pricing from third-party brokers-dealers on a sample of securities that are then compared to the pricing received. The pricing service uses standard observable inputs when available, for example: benchmark yields, reported trades, broker-dealer quotes, issuer spreads, benchmark securities, and bids and offers, among others. For certain security types, additional inputs may be used, or some inputs may not be applicable. It is not customary for Regions to adjust the pricing received for the available for sale portfolio. In the event that prices are adjusted, Regions classifies the measurement as a Level 3 measurement.

Mortgage loans held for sale consist of residential first mortgage loans and commercial mortgages held for sale. Regions has elected to measure certain residential and commercial mortgage loans held for sale at fair value by applying the fair value option (see additional discussion under the “Fair Value Option” section in Note 21). The residential first mortgage loans held for sale are valued based on traded market prices of similar assets where available and/or discounted cash flows at market interest rates, adjusted for securitization activities that include servicing value and market conditions, a Level 2 measurement. The commercial mortgage loans held for sale are valued based on traded market prices for comparable commercial mortgage-backed securitizations, into which the loans will be placed, adjusted for movements of interest rates and credit spreads, a Level 3 measurement due to the unobservable inputs included in the credit spreads for bonds in commercial mortgage-backed securitizations.

Marketable equity securities, which primarily consist of assets held for certain employee benefits and money market funds, are valued based on quoted market prices of identical assets on active exchanges; these valuations are Level 1 measurements.

Residential mortgage servicing rights are valued using an option-adjusted spread valuation approach, a Level 3 measurement. The underlying assumptions and estimated values are corroborated at least quarterly by values received from independent third parties. See Note 6 for information regarding the servicing of financial assets and additional details regarding the assumptions relevant to this valuation.

Derivative assets and liabilities, which primarily consist of interest rate, foreign exchange, and commodity contracts that include forwards, futures, options and swaps, are included in other assets and other liabilities (as applicable) on the consolidated balance sheets. Interest rate swaps are predominantly traded in over-the-counter markets and, as such, values are determined using widely accepted discounted cash flow models, which are Level 2 measurements. These discounted cash flow models use projections of future cash payments/receipts that are discounted at an appropriate index rate. Regions utilizes forward curves as fair value measurement inputs for the valuation of interest rate and commodity derivatives. The projected future cash flows are sourced from an assumed yield curve, which is consistent with industry standards and conventions. These valuations are adjusted for the unsecured credit risk at the reporting date, which considers collateral posted and the impact of master netting agreements. For options and futures contracts traded in over-the-counter markets, values are determined using discounted cash

flow analyses and option pricing models based on market rates and volatilities, which are Level 2 measurements. Interest rate lock commitments on loans intended for sale and risk participations categorized as credit derivatives are valued using option pricing models that incorporate significant unobservable inputs, and therefore are Level 3 measurements.

ITEMS MEASURED AT FAIR VALUE ON A NON-RECURRING BASIS

From time to time, certain assets may be recorded at fair value on a non-recurring basis. These non-recurring fair value adjustments typically are a result of the application of lower of cost or fair value accounting or a write-down occurring during the period. For example, if the fair value of an asset in these categories falls below its cost basis, it is considered to be at fair value at the end of the period of the adjustment. In periods where there is no adjustment, the asset is generally not considered to be at fair value. The following is a description of the valuation methodologies used for assets measured at fair value on a non-recurring basis.

Foreclosed property and other real estate is carried in other assets at the lower of the recorded investment in the loan or fair value less estimated costs to sell the property. The fair value for foreclosed property that is based on either observable transactions of similar instruments or formally committed sale prices is classified as a Level 2 measurement. If no formally committed sale price is available, Regions also obtains valuations from professional valuation experts and/or third party appraisers. Updated valuations are obtained on at least an annual basis. Foreclosed property exceeding established dollar thresholds is valued based on appraisals. Appraisals are performed by third-parties with appropriate professional certifications and conform to generally accepted appraisal standards as evidenced by the Uniform Standards of Professional Appraisal Practice. Regions’ policies related to appraisals conform to regulations established by the Financial Institutions Reform, Recovery and Enforcement Act of 1989 and other regulatory guidance. Professional valuations are considered Level 2 measurements because they are based largely on observable inputs. Regions has a centralized appraisal review function that is responsible for reviewing appraisals for compliance with banking regulations and guidelines as well as appraisal standards. Based on these reviews, Regions may make adjustments to the market value conclusions determined in the appraisals of real estate (either as other real estate or loans held for sale) when the appraisal review function determines that the valuation is based on inappropriate assumptions or where the conclusion is not sufficiently supported by the market data presented in the appraisal. Adjustments to the market value conclusions are discussed with the professional valuation experts and/or third-party appraisers; the magnitude of the adjustments that are not mutually agreed upon is insignificant. Adjustments, if made, must be based on sufficient information available to support an alternate opinion of market value. An estimated standard discount factor, which is updated at least annually, is applied to the appraisal amount for certain commercial and investor real estate properties when the recorded investment in the loan is transferred into foreclosed property. Internally adjusted valuations are considered Level 3 measurements as management uses assumptions that may not be observable in the market. These non-recurring fair value measurements are typically recorded on the date an updated offered quote, appraisal, or third-party valuation is received.

Equity investments without a readily determinable fair value are adjusted prospectively to estimated fair value when an observable price transaction for a same or similar investment with the same issuer occurs; these valuations are Level 3 measurements.

Loans held for sale for which the fair value option has not been elected are recorded at the lower of cost or fair value and therefore may be reported at fair value on a non-recurring basis. The fair values for commercial loans held for sale are based on Company-specific data not observable in the market. These valuations are Level 3 measurements.

FAIR VALUE OF FINANCIAL INSTRUMENTS

The following methods and assumptions were used by the Company in estimating fair values of financial instruments that are not disclosed above:

Cash and cash equivalents: The carrying amounts reported in the consolidated balance sheets and statements of cash flows approximate the estimated fair values. Because these amounts generally relate to either currency or highly liquid assets, these are considered Level 1 valuations.

Debt securities held to maturity: The fair values of debt securities held to maturity are estimated in the same manner as the corresponding debt securities available for sale, which are measured at fair value on a recurring basis.

Loans (excluding sales-type, direct financing, and leveraged leases), net of unearned income and allowance for loan losses: A discounted cash flow method under the income approach is utilized to estimate the fair value of the loan portfolio. The discounted cash flow method relies upon assumptions about the amount and timing of scheduled principal and interest payments, principal prepayments, and current market rates. The loan portfolio is aggregated into categories based on loan type and credit quality. For each loan category, weighted average statistics, such as coupon rate, age, and remaining term are calculated. These are Level 3 valuations.

Other earning assets (excluding equity investments and operating leases): The carrying amounts reported in the consolidated balance sheets approximate the estimated fair values. While these instruments are not actively traded in the market, the majority of the inputs required to value them are actively quoted and can be validated through external sources.

Accordingly, these are Level 2 valuations. The fair values of certain other earning assets are estimated using quoted market prices of identical instruments in active markets and are considered Level 1 measurements.

Deposits: The fair value of non-interest-bearing demand accounts, interest-bearing transaction accounts, savings accounts, money market accounts and certain other time deposit accounts is the amount payable on demand at the reporting date (i.e., the carrying amount). Fair values for certificates of deposit are estimated by using discounted cash flow analyses, based on market spreads to benchmark rates, and are considered Level 2 valuations.

Long-term borrowings: The fair values of certain long term borrowings are estimated using quoted market prices of identical instruments in non-active markets and are considered Level 2 valuations. Otherwise, valuations are based on non-binding broker quotes and are considered Level 3 valuations.

Loan commitments and letters of credit: The fair value of these instruments is reasonably estimated by the carrying value of deferred fees plus the unfunded loan commitments reserve related to the creditworthiness of the counterparty. Because the valuation inputs are not observable in the market and are considered Company specific, these are Level 3 valuations.

See Note 21 for additional information related to fair value measurements

New Accounting Pronouncements, Policy [Policy Text Block]

RECENT ACCOUNTING PRONOUNCEMENTS

The following table provides a brief description of accounting standards adopted in 2022 and those that could have a material impact to Regions’ consolidated financial statements upon adoption in the future.

Standard			Description			Required Date of Adoption			Effect on Regions' financial statements or other significant matters
Standards Adopted (or partially adopted) in 2022
ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging— Contracts in Entity’s Own Equity (Subtopic 815-40)			This Update simplifies accounting for convertible instruments by removing certain separation models. Additionally, it revises and clarifies guidance on the derivatives scope exception to make the exception easier to apply.			January 1, 2022			The adoption of this guidance did not have a material impact.
ASU 2021-04, Earnings Per Share (Topic 260), Debt—Modifications and Extinguishments (Subtopic 470-50), Compensation — Stock Compensation (Topic 718), and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40)			This Update clarifies how an issuer should account for modifications made to equity-classified written call options (i.e. a warrant to purchase the issuer’s common stock). The guidance in the Update requires the issuer to treat a modification of an equity-classified warrant that does not cause the warrant to become liability-classified as an exchange of the original warrant for a new warrant. This guidance applies whether the modification is structured as an amendment to the terms and conditions of the warrant or as termination of the original warrant and issuance of a new warrant.			January 1, 2022			The adoption of this guidance did not have a material impact.
ASU 2021-05 Leases (Topic 842): Lessors—Certain Leases with Variable Lease Payments			This Update amends the lessor lease classification guidance under ASC 842. Under the amendments, a lessor must classify a lease that includes variable lease payments that do not depend on an index or rate as an operating lease if it would otherwise be classified as a sales-type or direct financing lease and would result in the recognition of a loss at a lease commencement. The amendments address concerns raised during the FASB’s post implementation review regarding recognition of an immediate loss for these leases, as would otherwise be required.			January 1, 2022			The adoption of this guidance did not have a material impact.
ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers			The amendments in this Update require that an entity (acquirer) recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606, Revenue from Contracts with Customers, rather than using fair value. At the acquisition date, an acquirer should account for the related revenue contracts in accordance with Topic 606 as if it had originated the contracts.			January 1, 2023 Early adoption is permitted.			The early adoption of this guidance did not have a material impact.

Standard			Description			Required Date of Adoption			Effect on Regions' financial statements or other significant matters
Standards Adopted (or partially adopted) in 2022 (continued)
ASU 2022-01—Derivatives and Hedging (Topic 815): Fair Value Hedging—Portfolio Layer Method			This Update represents the final amended guidance to the ‘last-of-layer’ hedge model for fair value hedge relationships. The last-of-layer method allowed for essentially a single hedge for a given portfolio of only prepayable assets. The ‘portfolio layer’ method will make the hedging asset side of the balance sheet easier as it allows for more flexibility in the use of derivatives and structures that best align with management's objectives for hedging purposes. Multiple hedged layers are permitted in fair value hedge relationships for a closed portfolio of financial assets. Both prepayable and non-prepayable financial instruments may be used and included. The Update permits reclassification of debt securities from held-to-maturity to available-for-sale upon adoption with restrictions. Portfolio layer method hedging must be applied to those debt securities. Also, the decision to reclassify must be within 30 days after the date of adoption, and securities would need to be included in a closed portfolio that is designed in a portfolio layer method hedge within that 30-day period.			January 1, 2023 Early adoption is permitted.			The early adoption of this guidance did not have a material impact.
ASU 2022-06— Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848			This Update defers the sunset date for applying reference rate reform relief in Topic 848 to December 31, 2024 from December 31, 2022.			Effective upon issuance			The adoption of this guidance did not have a material impact.

Standard			Description			Required Date of Adoption			Effect on Regions' financial statements or other significant matters
Standards Not Yet Adopted
ASU 2022-02, Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures			This Update is intended to improve the decision usefulness of information provided to investors about certain loan refinancings, restructurings, and write-offs. The amendments in the Update eliminate the accounting guidance for TDRs by creditors that have adopted CECL while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors made to borrowers experiencing financial difficulty. The Update also requires that a public business entity disclose current-period gross write-offs by year of origination for financing receivables and net investment in leases. The amendments in this Update should be applied prospectively, except for the transition method related to the recognition and measurement of TDRs for which there is an option to apply a modified retrospective transition method, resulting in a cumulative-effect adjustment to retained earnings in the period of adoption.			January 1, 2023			Regions adopted this guidance as of January 1, 2023 with no material impact.
2022-03, Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions			This Update clarifies how the fair value of equity securities subject to contractual sale restrictions is determined. ASU 2022-03 clarifies that a contractual sale restriction should not be considered in measuring fair value. It also requires entities with investments in equity securities subject to contractual sale restrictions to disclose certain qualitative and quantitative information about such securities.			January 1, 2023			Regions adopted this guidance as of January 1, 2023 with no material impact.

Disclosure of accounting policy for transfers and servicing financial assets, including securitization transactions as well as repurchase and resale agreements. This disclosure may include how the entity (1) determines whether a transaction is accounted for as a sale; (2) accounts for a sale transaction, including the initial and subsequent accounting for any interests that the entity obtains or continues to hold in the transaction, how such interests are valued, and the significant assumptions used in the valuation; (3) accounts for a transaction that does not qualify for sale treatment (that is, a financing); and (4) accounts for its servicing assets and liabilities ("servicing"), including how such servicing is measured initially and subsequently, and the methodology and significant assumptions used to value such servicing.
