Debt securities with carrying values of $8.3 billion and $7.9 billion at June 30, 2019 , and December 31, 2018 , respectively, were pledged to secure public funds, trust deposits and certain borrowing arrangements. Included within total pledged securities is approximately $24 million of encumbered U.S. Treasury securities at both June 30, 2019 , and December 31, 2018 . The amortized cost and estimated fair value of debt securities held to maturity and debt securities available for sale at June 30, 2019 , by contractual maturity, are shown below. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Amortized Cost Estimated Fair Value (In millions) Debt securities held to maturity: Mortgage-backed securities: Residential agency $ 816 $ 804 Commercial agency 631 644 $ 1,447 $ 1,448 Debt securities available for sale: Due in one year or less $ 74 $ 75 Due after one year through five years 1,016 1,031 Due after five years through ten years 319 333 Due after ten years 56 59 Mortgage-backed securities: Residential agency 16,717 16,751 Residential non-agency 2 2 Commercial agency 3,670 3,741 Commercial non-agency 699 707 $ 22,553 $ 22,699 The following tables present gross unrealized losses and the related estimated fair value of debt securities held to maturity and debt securities available for sale at June 30, 2019 , and December 31, 2018 . For debt securities transferred to held to maturity from available for sale, the analysis in the tables below is comparing the securities' original amortized cost to its current estimated fair value. These securities are segregated between investments that have been in a continuous unrealized loss position for less than twelve months and for twelve months or more.

The decrease in the number of securities and the total amount of unrealized losses from year-end 2018 was primarily due to changes in market interest rates. In instances where an unrealized loss existed, there was no indication of an adverse change in credit on the underlying positions in the tables above. As it relates to these positions, management believes no individual unrealized loss, other than those discussed below, represented an OTTI as of those dates. The Company does not intend to sell, and it is not more likely than not that the Company will be required to sell, the positions before the recovery of their amortized cost basis, which may be at maturity. As part of the Company's normal process for evaluating OTTI, management did identify a limited number of positions where an OTTI was believed to exist in certain periods, as shown in the table below. Gross realized gains and gross realized losses on sales of debt securities available for sale are shown in the table below. The cost of securities sold is based on the specific identification method.

Loans and the Allowance for Credit Losses	LOANS AND THE ALLOWANCE FOR CREDIT LOSSES LOANS The following table presents the distribution of Regions' loan portfolio by segment and class, net of unearned income: June 30, 2019 December 31, 2018 (In millions, net of unearned income) Commercial and industrial $ 40,438 $ 39,282 Commercial real estate mortgage—owner-occupied 5,455 5,549 Commercial real estate construction—owner-occupied 415 384 Total commercial 46,308 45,215 Commercial investor real estate mortgage 4,795 4,650 Commercial investor real estate construction 1,658 1,786 Total investor real estate 6,453 6,436 Residential first mortgage 14,253 14,276 Home equity 8,802 9,257 Indirect—vehicles 2,415 3,053 Indirect—other consumer 2,796 2,349 Consumer credit card 1,303 1,345 Other consumer 1,223 1,221 Total consumer 30,792 31,501 $ 83,553 $ 83,152 During the six months ended June 30, 2019 and 2018, Regions purchased approximately $526 million and $215 million in indirect-other consumer and commercial and industrial loans from third parties, respectively. In January 2019, Regions decided to discontinue its indirect auto lending business due to competition-based margin compression impacting overall returns on the portfolio. Regions ceased originating new indirect auto loans in the first quarter of 2019 and completed any in-process indirect auto loan closings at the end of the second quarter of 2019. The Company will remain in the direct auto lending business. At June 30, 2019 , $21.7 billion in securities and net eligible loans held by Regions were pledged to secure current and potential borrowings from the FHLB. At June 30, 2019 , an additional $25.2 billion in net eligible loans held by Regions were pledged to the FRB for potential borrowings. ALLOWANCE FOR CREDIT LOSSES Regions determines the appropriate level of the allowance on a quarterly basis. Refer to Note 1 “Summary of Significant Accounting Policies” to the consolidated financial statements to the Annual Report on Form 10-K for the year ended December 31, 2018 , for a description of the methodology. ROLLFORWARD OF ALLOWANCE FOR CREDIT LOSSES The following tables present analyses of the allowance for credit losses by portfolio segment for the three and six months ended June 30, 2019 and 2018. The total allowance for loan losses and the related loan portfolio ending balances are disaggregated to detail the amounts derived through individual evaluation and collective evaluation for impairment. The allowance for loan losses related to individually evaluated loans is attributable to reserves for non-accrual commercial and investor real estate loans and all TDRs. The allowance for loan losses and the loan portfolio ending balances related to collectively evaluated loans is attributable to the remainder of the portfolio.

Commercial —The commercial portfolio segment includes commercial and industrial loans to commercial customers for use in normal business operations to finance working capital needs, equipment purchases or other expansion projects. Commercial also includes owner-occupied commercial real estate mortgage loans to operating businesses, which are loans for long-term financing of land and buildings, and are repaid by cash flow generated by business operations. Owner-occupied construction loans are made to commercial businesses for the development of land or construction of a building where the repayment is derived from revenues generated from the business of the borrower. Collection risk in this portfolio is driven by the creditworthiness of underlying borrowers, particularly cash flow from customers’ business operations, and the sensitivity to market fluctuations in commodity prices. Investor Real Estate —Loans for real estate development are repaid through cash flow related to the operation, sale or refinance of the property. This portfolio segment includes extensions of credit to real estate developers or investors where repayment is dependent on the sale of real estate or income generated from the real estate collateral. A portion of Regions’ investor real estate portfolio segment consists of loans secured by residential product types (land, single-family and condominium loans) within Regions’ markets. Additionally, these loans are made to finance income-producing properties such as apartment buildings, office and industrial buildings, and retail shopping centers. Loans in this portfolio segment are particularly sensitive to the valuation of real estate. Consumer —The consumer portfolio segment includes residential first mortgage, home equity, indirect-vehicles, indirect-other consumer, consumer credit card, and other consumer loans. Residential first mortgage loans represent loans to consumers to finance a residence. These loans are typically financed over a 15 to 30 year term and, in most cases, are extended to borrowers to finance their primary residence. Home equity lending includes both home equity loans and lines of credit. This type of lending, which is secured by a first or second mortgage on the borrower’s residence, allows customers to borrow against the equity in their home. Real estate market values as of the time the loan or line is secured directly affect the amount of credit extended and, in addition, changes in these values impact the depth of potential losses. Indirect-vehicles lending, which is lending initiated through third-party business partners, largely consists of loans made through automotive dealerships. Indirect-other consumer lending represents other point of sale lending through third parties. Consumer credit card lending includes Regions branded consumer credit card accounts. Other consumer loans include other revolving consumer accounts, direct consumer loans, and overdrafts. Loans in this portfolio segment are sensitive to unemployment and other key consumer economic measures. CREDIT QUALITY INDICATORS The following tables present credit quality indicators for portfolio segments and classes, excluding loans held for sale, as of June 30, 2019 , and December 31, 2018 . Commercial and investor real estate portfolio segments are detailed by categories related to underlying credit quality and probability of default. Regions assigns these categories at loan origination and reviews the relationship utilizing a risk-based approach on, at minimum, an annual basis or at any time management becomes aware of information affecting the borrowers' ability to fulfill their obligations. Both quantitative and qualitative factors are considered in this review process. These categories are utilized to develop the associated allowance for credit losses. • Pass—includes obligations where the probability of default is considered low; • Special Mention—includes obligations that have potential weakness that may, if not reversed or corrected, weaken the credit or inadequately protect the Company’s position at some future date. Obligations in this category may also be subject to economic or market conditions that may, in the future, have an adverse effect on debt service ability; • Substandard Accrual—includes obligations that exhibit a well-defined weakness that presently jeopardizes debt repayment, even though they are currently performing. These obligations are characterized by the distinct possibility that the Company may incur a loss in the future if these weaknesses are not corrected; • Non-accrual—includes obligations where management has determined that full payment of principal and interest is in doubt. Substandard accrual and non-accrual loans are often collectively referred to as “classified.” Special mention, substandard accrual, and non-accrual loans are often collectively referred to as “criticized and classified.” Classes in the consumer portfolio segment are disaggregated by accrual status.

At June 30, 2019, less than $1 million of commercial and investor real estate loans modified as TDRs during the three months ended June 30, 2019 were on non-accrual status. At June 30, 2019 , Regions had restructured binding unfunded commitments totaling $6 million where a concession was granted and the borrower was in financial difficulty.

Transfers and Servicing of Financial Assets [Abstract]
Servicing of Financial Assets	SERVICING OF FINANCIAL ASSETS RESIDENTIAL MORTGAGE BANKING ACTIVITIES 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 mortgages in the servicing portfolio could result in significant changes in the valuation adjustments, thus creating potential volatility in the carrying amount of residential MSRs. The Company compares fair value estimates and assumptions to observable market data where available, and also considers recent market activity and actual portfolio experience. The table below presents an analysis of residential MSRs under the fair value measurement method: Three Months Ended June 30 Six Months Ended June 30 2019 2018 2019 2018 (In millions) Carrying value, beginning of period $ 386 $ 356 $ 418 $ 336 Additions 8 9 15 17 Increase (decrease) in fair value: Due to change in valuation inputs or assumptions (43 ) 10 (71 ) 32 Economic amortization associated with borrower repayments (1) (14 ) (13 ) (25 ) (23 ) Carrying value, end of period $ 337 $ 362 $ 337 $ 362 ________ (1) "Economic amortization associated with borrower repayments" includes both total loan payoffs as well as partial paydowns. On March 27, 2019, the Company sold $167 million of affordable housing residential mortgage loans and as part of the transaction kept the rights to service the loans, which resulted in a retained residential MSR of approximately $2 million . Data and assumptions used in the fair value calculation, as well as the valuation’s sensitivity to rate fluctuations, related to residential MSRs (excluding related derivative instruments) are as follows: June 30 2019 2018 (Dollars in millions) Unpaid principal balance $ 35,309 $ 31,140 Weighted-average CPR (%) 12.5 % 8.6 % Estimated impact on fair value of a 10% increase $ (19 ) $ (22 ) Estimated impact on fair value of a 20% increase $ (35 ) $ (41 ) Option-adjusted spread (basis points) 763 825 Estimated impact on fair value of a 10% increase $ (10 ) $ (12 ) Estimated impact on fair value of a 20% increase $ (20 ) $ (24 ) Weighted-average coupon interest rate 4.2 % 4.2 % Weighted-average remaining maturity (months) 279 280 Weighted-average servicing fee (basis points) 27.2 27.5 The sensitivity calculations above are hypothetical and should not be considered to be predictive of future performance. Changes in fair value based on adverse changes in assumptions generally cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. Also, the effect of an adverse variation in a particular assumption on the fair value of the residential MSRs is calculated without changing any other assumption, while in reality changes in one factor may result in changes in another, which may either magnify or counteract the effect of the change. The derivative instruments utilized by Regions would serve to reduce the estimated impacts to fair value included in the table above. The following table presents servicing related fees, which include contractually specified servicing fees, late fees and other ancillary income resulting from the servicing of residential mortgage loans: Three Months Ended June 30 Six Months Ended June 30 2019 2018 2019 2018 (In millions) Servicing related fees and other ancillary income $ 26 $ 23 $ 52 $ 46 Residential mortgage loans are sold in the secondary market with standard representations and warranties regarding certain characteristics such as the quality of the loan, the absence of fraud, the eligibility of the loan for sale and the future servicing associated with the loan. Regions may be required to repurchase these loans at par, or make-whole or indemnify the purchasers for losses incurred when representations and warranties are breached. Regions maintains an immaterial repurchase liability related to residential mortgage loans sold with representations and warranty provisions. This repurchase liability is reported in other liabilities on the consolidated balance sheets and reflects management’s estimate of losses based on historical repurchase and loss trends, as well as other factors that may result in anticipated losses different from historical loss trends. Adjustments to this reserve are recorded in other non-interest expense on the consolidated statements of income. COMMERCIAL MORTGAGE BANKING ACTIVITIES Regions is an approved DUS lender. The DUS program provides liquidity to the multi-family housing market. In connection with the DUS program, Regions services commercial mortgage loans, retains commercial MSRs and intangible assets associated with the DUS license, and assumes a loss share guarantee associated with the loans. See Note 1 "Summary of Significant Accounting Policies" in the 2018 Annual Report on Form 10-K for additional information. Also see Note 12 for additional information related to the guarantee. As of both June 30, 2019 and December 31, 2018 , the DUS servicing portfolio was approximately $3.6 billion . The related commercial MSRs were approximately $55 million and $56 million at June 30, 2019 and December 31, 2018 , respectively. The estimated fair value of the loss share guarantee was approximately $5 million at June 30, 2019 and $4 million at December 31, 2018 .

Leases [Abstract]
Leases Lessee	LEASES LESSEE 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. The remainder of the lease portfolio is comprised of equipment leases that have remaining lease terms of 1 year to 3 years. As of June 30, 2019 , assets and liabilities recorded under operating leases for properties were $430 million and $505 million , respectively. The difference between the asset and liability balance is largely the result of lease liabilities that existed prior to the January 1, 2019 adoption of the new accounting guidance for leases. The asset is recorded within other assets and the lease liability is recorded within other liabilities on the consolidated balance sheet. Lease expense is comprised of the following: Three Months Ended June 30, 2019 Six Months Ended June 30, 2019 (In millions) Operating lease cost $ 20 $ 41 Other information related to operating leases is as follows: June 30, 2019 Weighted-average remaining lease term (years) 9.2 Weighted-average discount rate (%) 3.3 % Future, undiscounted minimum lease payments on operating leases are as follows: June 30, 2019 (In millions) 2019 (excluding the six months ended June 30, 2019) $ 46 2020 91 2021 82 2022 73 2023 65 Thereafter 256 Total lease payments $ 613 Less: Imputed interest 108 Total present value of lease liabilities $ 505
Leases Lessor	LESSOR Regions engages in both direct financing and sales-type leasing. Regions also has portfolios of leveraged and operating 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. The sales-type, direct financing and leveraged leases are recorded within loans on the consolidated balance sheet and operating leases are recorded within other earning assets on the consolidated balance sheet.

Stockholders' Equity and Accumulated Other Comprehensive Income (Loss)	STOCKHOLDERS’ EQUITY AND ACCUMULATED OTHER COMPREHENSIVE INCOME (LOSS) PREFERRED STOCK The following table presents a summary of the non-cumulative perpetual preferred stock: June 30, 2019 December 31, 2018 Issuance Date Earliest Redemption Date Dividend Rate Liquidation Amount Carrying Amount Carrying Amount (Dollars in millions) Series A 11/1/2012 12/15/2017 6.375 % $ 500 $ 387 $ 387 Series B 4/29/2014 9/15/2024 6.375 % (1) 500 433 433 Series C 4/30/2019 5/15/2029 5.700 % (2) 500 490 — $ 1,500 $ 1,310 $ 820 _________ (1) Dividends, if declared, will be paid quarterly at an annual rate equal to (i) for each period beginning prior to September 15, 2024, 6.375% , and (ii) for each period beginning on or after September 15, 2024, three-month LIBOR plus 3.536% . (2) Dividends, if declared, will be paid quarterly at an annual rate equal to (i) for each period beginning prior to August 15, 2029, 5.700% , and (ii) for each period beginning on or after August 15, 2029, three-month LIBOR plus 3.148% . For each preferred stock issuance listed above, Regions issued depositary shares, each representing a 1/40th ownership interest in a share of the Company's preferred stock, with a liquidation preference of $1,000.00 per share of preferred stock (equivalent to $25.00 per depositary share). Dividends on the preferred stock, if declared, accrue and are payable quarterly in arrears. The preferred stock has no stated maturity and redemption is solely at Regions' option, subject to regulatory approval, in whole, or in part, after the earliest redemption date or in whole, but not in part, within 90 days following a regulatory capital treatment event for the Series A preferred stock or at any time following a regulatory capital treatment event for the Series B and Series C preferred stock. The Board of Directors declared $16 million in cash dividends on both Series A and Series B Preferred Stock during the first six months of 2019 and 2018. The initial quarterly dividend for Series C Preferred Stock was declared on July 24, 2019, therefore there were no cash dividends for the first six months of 2019. In the event Series A, Series B, and Series C preferred shares are redeemed at the liquidation amounts, $113 million , $67 million , and $10 million excess of the redemption amount over the carrying amount will be recognized, respectively. Approximately $100 million of Series A preferred dividends that were recorded as a reduction of preferred stock, including related surplus, will be recorded as a reduction to retained earnings, and approximately $13 million of related issuance costs that were recorded as a reduction of preferred stock, including related surplus, will be recorded as a reduction to net income available to common shareholders. Approximately $52 million of Series B preferred dividends that were recorded as a reduction of preferred stock, including related surplus, will be recorded as a reduction to retained earnings, and approximately $15 million of related issuance costs that were recorded as a reduction of preferred stock, including related surplus, will be recorded as a reduction to net income available to common shareholders. Approximately $10 million of Series C issuance costs that were recorded as a reduction of preferred stock, including related surplus, will be recorded as a reduction to net income available to common shareholders. COMMON STOCK Regions was not required to participate in the 2019 CCAR; however, as required, the Company did submit its planned capital actions to the Federal Reserve for the third quarter of 2019 through the second quarter of 2020. During the second quarter of 2019, the Board authorized the repurchase of up to $1.37 billion of the Company's common stock, permitting repurchases from the beginning of the third quarter of 2019 through the second quarter of 2020. The Company began to repurchase shares under this plan in the third quarter of 2019, and as of August 6, 2019, Regions had repurchased approximately 9.3 million shares of common stock at a total cost of approximately $144.8 million . All of these shares were retired upon repurchase and, therefore will not be included in treasury stock. Prior to the new common stock repurchase plan, Regions had authorization to repurchase $2.031 billion in common shares. As of June 30, 2019, Regions had repurchased approximately 115.38 million shares of common stock, through open market purchases and a contractual repurchase agreement, at a total cost of $2.031 billion under this plan and concluded the plan during the second quarter of 2019. Regions' Board declared a cash dividend for both the first and second quarter of 2019 of $0.14 per share, totaling $0.28 per common share for the first six months of 2019.

(2) On April 4, 2018, Regions entered into a stock purchase agreement to sell Regions Insurance Group, Inc to BB&T Insurance Holdings, Inc. The transaction closed on July 2, 2018. The transaction generated an after-tax gain of $196 million . On January 11, 2012, Regions entered into a stock purchase agreement to sell Morgan Keegan and Company and related affiliates to Raymond James Financial Inc. The sale closed on April 2, 2012. (3) In a period where there is a loss from discontinued operations, basic weighted-average common shares outstanding are used to determine both basic and diluted earnings per share. The effects from the assumed exercise of 9 million and 7 million stock options, restricted stock units and awards and performance stock units for the three and six months ended June 30, 2019 respectively, were not included in the above computations of diluted earnings per common share because such amounts would have had an antidilutive effect on earnings per common share. The effects from the assumed exercise of 6 million stock options, restricted stock units and awards and performance stock units for both the three and six months ended June 30, 2018 was not included in the above computations of diluted earnings per common share because such amounts would have had an antidilutive effect on earnings per common share.

There is no fair value presented for contracts that are characterized as settled daily. (2) Estimated fair value includes premium and change in fair value of the interest rate floors. (3) As of both June 30, 2019 and December 31, 2018 , financial instruments posted of $24 million were not offset in the consolidated balance sheets. HEDGING DERIVATIVES Derivatives entered into to manage interest rate risk and facilitate asset/liability management strategies are designated as hedging derivatives. Derivative financial instruments that qualify in a hedging relationship are classified, based on the exposure being hedged, as either fair value hedges or cash flow hedges. See Note 1 "Summary of Significant Accounting Policies" of the Annual Report on Form 10-K for the year ended December 31, 2018 , for additional information regarding accounting policies for derivatives. FAIR VALUE HEDGES Fair value hedge relationships mitigate exposure to the change in fair value of an asset, liability or firm commitment. Regions enters into interest rate swap agreements to manage interest rate exposure on the Company’s fixed-rate borrowings. These agreements involve the receipt of fixed-rate amounts in exchange for floating-rate interest payments over the life of the agreements. Regions enters into interest rate swap agreements to manage interest rate exposure on certain of the Company's fixed-rate available for sale debt securities. These agreements involve the payment of fixed-rate amounts in exchange for floating-rate interest receipts. CASH FLOW HEDGES Cash flow hedge relationships mitigate exposure to the variability of future cash flows or other forecasted transactions. Regions enters into interest rate swap and floor agreements to manage overall cash flow changes related to interest rate risk exposure on LIBOR-based loans. The agreements effectively modify the Company’s exposure to interest rate risk by utilizing receive fixed/pay LIBOR interest rate swaps and interest rate floors. Regions recognized an unrealized after-tax gain of $45 million and $125 million in accumulated other comprehensive income (loss) at June 30, 2019 and 2018 , respectively, related to discontinued cash flow hedges of loan instruments, which will be amortized into earnings in conjunction with the recognition of interest payments through 2025. Regions recognized pre-tax income of $3 million and $14 million during the three months ended June 30, 2019 and 2018 , respectively, and pre-tax income of $8 million and $29 million during the six months ended June 30, 2019 and 2018 , respectively, related to the amortization of discontinued cash flow hedges of loan instruments. Regions expects to reclassify into earnings approximately $11 million in pre-tax income due to the receipt or payment of interest payments and floor premium amortization on all cash flow hedges within the next twelve months. Included in this amount is $8 million in pre-tax net gains related to the amortization of discontinued cash flow hedges. The maximum length of time over which Regions is hedging its exposure to the variability in future cash flows for forecasted transactions is approximately eight years as of June 30, 2019 , and a portion of these hedges are forward starting. The following tables present the effect of hedging derivative instruments on the consolidated statements of income and the total amounts for the respective line items effected: Three Months Ended June 30, 2019 Interest Income Interest Expense Debt securities-taxable Loans, including fees Long-term borrowings (In millions) Total amounts presented in the consolidated statements of income $ 163 $ 992 $ 96 Gains/(losses) on fair value hedging relationships: Interest rate contracts: Amounts related to interest settlements on derivatives $ — $ — $ (5 ) Recognized on derivatives (1 ) — 57 Recognized on hedged items 1 — (57 ) Income (expense) recognized on fair value hedges $ — $ — $ (5 ) Gains/(losses) on cash flow hedging relationships: (1) Interest rate contracts: Realized gains (losses) reclassified from AOCI into net income (2) $ — $ (8 ) $ — Income (expense) recognized on cash flow hedges $ — $ (8 ) $ — Three Months Ended June 30, 2018 Interest Income Interest Expense Debt securities-taxable Loans, including fees Long-term borrowings (In millions) Total amounts presented in the consolidated statements of income $ 156 $ 881 $ 73 Gains/(losses) on fair value hedging relationships: Interest rate contracts: Amounts related to interest settlements on derivatives $ (1 ) $ — $ (4 ) Recognized on derivatives 2 — (9 ) Recognized on hedged items (2 ) — 8 Income (expense) recognized on fair value hedges $ (1 ) $ — $ (5 ) Gains/(losses) on cash flow hedging relationships: (1) Interest rate contracts: Realized gains (losses) reclassified from AOCI into net income (2) $ — $ 5 $ — Income (expense) recognized on cash flow hedges $ — $ 5 $ — Six Months Ended June 30, 2019 Interest Income Interest Expense Debt securities-taxable Loans, including fees Long-term borrowings (In millions) Total amounts presented in the consolidated statements of income $ 328 $ 1,973 $ 198 Gains/(losses) on fair value hedging relationships: Interest rate contracts: Amounts related to interest settlements on derivatives $ — $ — $ (11 ) Recognized on derivatives (2 ) — 90 Recognized on hedged items 2 — (90 ) Income (expense) recognized on fair value hedges $ — $ — $ (11 ) Gains/(losses) on cash flow hedging relationships: (1) Interest rate contracts: Realized gains (losses) reclassified from AOCI into net income (2) $ — $ (16 ) $ — Income (expense) recognized on cash flow hedges $ — $ (16 ) $ — Six Months Ended June 30, 2018 Interest Income Interest Expense Debt securities-taxable Loans, including fees Long-term borrowings (In millions) Total amounts presented in the consolidated statements of income $ 310 $ 1,732 $ 145 Gains/(losses) on fair value hedging relationships: Interest rate contracts: Amounts related to interest settlements on derivatives $ (1 ) $ — $ (5 ) Recognized on derivatives 5 — (41 ) Recognized on hedged items (5 ) — 40 Income (expense) recognized on fair value hedges $ (1 ) $ — $ (6 ) Gains/(losses) on cash flow hedging relationships: (1) Interest rate contracts: Realized gains (losses) reclassified from AOCI into net income (2) $ — $ 16 $ — Income (expense) recognized on cash flow hedges $ — $ 16 $ — _____ (1) See Note 6 for gain or (loss) recognized for cash flow hedges in AOCI.

The Company monitors and manages the net risk in this customer portfolio and enters into separate derivative contracts in order to reduce the overall exposure to pre-defined limits. For both derivatives with its end customers and derivatives Regions enters into to mitigate the risk in this portfolio, the Company is subject to market risk and the risk that the counterparty will default. The contracts in this portfolio are not designated as accounting hedges and are marked-to market through earnings (in capital markets fee income) and included in other assets and other liabilities, as appropriate. 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. At June 30, 2019 and December 31, 2018 , Regions had $389 million and $191 million , respectively, in total notional amount of interest rate lock commitments. Regions manages market risk on interest rate lock commitments and mortgage loans held for sale with corresponding forward sale commitments. Residential mortgage loans held for sale are recorded at fair value with changes in fair value recorded in mortgage income. Commercial mortgage loans held for sale are recorded at either the lower of cost or market or at fair value based on management's election. At June 30, 2019 and December 31, 2018 , Regions had $767 million and $429 million , respectively, in total notional amounts related to these forward sale commitments. Changes in mark-to-market from both interest rate lock commitments and corresponding forward sale commitments related to residential mortgage loans are included in mortgage income. Changes in mark-to-market from both interest rate lock commitments and corresponding forward sale commitments related to commercial mortgage loans are included in capital markets fee income. Regions has elected to account for residential MSRs at fair value with any changes to fair value being recorded within mortgage income. Concurrent with the election to use the fair value measurement method, Regions began using various derivative instruments, in the form of forward rate commitments, futures contracts, swaps and swaptions to mitigate the effect of changes in the fair value of its residential MSRs in its consolidated statements of income. As of June 30, 2019 and December 31, 2018 , the total notional amount related to these contracts was $4.1 billion and $5.7 billion , respectively. The following table presents the location and amount of gain or (loss) recognized in income on derivatives not designated as hedging instruments in the consolidated statements of income for the periods presented below: Three Months Ended June 30 Six Months Ended June 30 Derivatives Not Designated as Hedging Instruments 2019 2018 2019 2018 (In millions) Capital markets income: Interest rate swaps $ (4 ) $ 5 $ (3 ) $ 12 Interest rate options 5 6 7 13 Interest rate futures and forward commitments 3 1 4 2 Other contracts (1 ) 2 (1 ) 4 Total capital markets income 3 14 7 31 Mortgage income: Interest rate swaps 35 (6 ) 54 (24 ) Interest rate options 2 — 5 3 Interest rate futures and forward commitments (3 ) (1 ) (1 ) (4 ) Total mortgage income 34 (7 ) 58 (25 ) $ 37 $ 7 $ 65 $ 6 Credit risk, defined as all positive exposures not collateralized with cash or other assets or reserved for, at June 30, 2019 and December 31, 2018 , totaled approximately $358 million and $130 million , respectively. These amounts represent the net credit risk on all trading and other derivative positions held by Regions. CREDIT DERIVATIVES Regions has both bought and sold credit protection in the form of participations on interest rate swaps (swap participations). These swap participations, which meet the definition of credit derivatives, were entered into in the ordinary course of business to serve the credit needs of customers. Swap participations, whereby Regions has purchased credit protection, entitle Regions to receive a payment from the counterparty if the customer fails to make payment on any amounts due to Regions upon early termination of the swap transaction and have maturities between 2019 and 2026. Swap participations, whereby Regions has sold credit protection have maturities between 2019 and 2038. For contracts where Regions sold credit protection, Regions would be required to make payment to the counterparty if the customer fails to make payment on any amounts due to the counterparty upon early termination of the swap transaction. Regions bases the current status of the prepayment/performance risk on bought and sold credit derivatives on recently issued internal risk ratings consistent with the risk management practices of unfunded commitments. Regions’ maximum potential amount of future payments under these contracts as of June 30, 2019 was approximately $600 million . This scenario would only occur if variable interest rates were at zero percent and all counterparties defaulted with zero recovery. The fair value of sold protection at June 30, 2019 and 2018 was immaterial. In transactions where Regions has sold credit protection, recourse to collateral associated with the original swap transaction is available to offset some or all of Regions’ obligation. Regions has bought credit protection in the form of credit default indices. These indices, which meet the definition of credit derivatives, were entered into in the ordinary course of business to economically hedge credit spread risk in commercial mortgage loans held for sale whereby the fair value option has been elected. Credit derivatives, whereby Regions has purchased credit protection, entitle Regions to receive a payment from the counterparty if losses on the underlying index exceed a certain threshold, dependent upon the tranche rating of the capital structure. CONTINGENT FEATURES Certain of Regions’ derivative instrument contracts with broker-dealers contain credit-related termination provisions and/or credit-related provisions regarding the posting of collateral, allowing those broker-dealers to terminate the contracts in the event that Regions’ and/or Regions Bank’s credit ratings falls below specified ratings from certain major credit rating agencies. The aggregate fair values of all derivative instruments with any credit-risk-related contingent features that were in a liability position on June 30, 2019 and December 31, 2018 , were $53 million and $45 million , respectively, for which Regions had posted collateral of $53 million and $43 million , respectively, in the normal course of business.

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS See Note 1 “Summary of Significant Accounting Policies” to the consolidated financial statements of the Annual Report on Form 10-K for the year ended December 31, 2018 for a description of valuation methodologies for assets and liabilities measured at fair value on a recurring and non-recurring basis. Assets and liabilities measured at fair value rarely transfer between Level 1 and Level 2 measurements. Marketable equity securities and debt securities available for sale may be periodically transferred to or from Level 3 valuation based on management’s conclusion regarding the observability of inputs used in valuing the securities. Such transfers are accounted for as if they occur at the beginning of a reporting period. The following table presents assets and liabilities measured at estimated fair value on a recurring basis and non-recurring basis as of June 30, 2019 and December 31, 2018 : June 30, 2019 December 31, 2018 Level 1 Level 2 Level 3 (1) Total Estimated Fair Value Level 1 Level 2 Level 3 (1) Total Estimated Fair Value (In millions) Recurring fair value measurements Debt securities available for sale: U.S. Treasury securities $ 176 $ — $ — $ 176 $ 280 $ — $ — $ 280 Federal agency securities — 44 — 44 — 43 — 43 Mortgage-backed securities (MBS): Residential agency — 16,751 — 16,751 — 16,624 — 16,624 Residential non-agency — — 2 2 — — 2 2 Commercial agency — 3,741 — 3,741 — 3,835 — 3,835 Commercial non-agency — 707 — 707 — 760 — 760 Corporate and other debt securities — 1,277 1 1,278 — 1,182 3 1,185 Total debt securities available for sale $ 176 $ 22,520 $ 3 $ 22,699 $ 280 $ 22,444 $ 5 $ 22,729 Loans held for sale $ — $ 433 $ — $ 433 $ — $ 251 $ — $ 251 Marketable equity securities $ 452 $ — $ — $ 452 $ 429 $ — $ — $ 429 Residential mortgage servicing rights $ — $ — $ 337 $ 337 $ — $ — $ 418 $ 418 Derivative assets: Interest rate swaps $ — $ 404 $ — $ 404 $ — $ 193 $ — $ 193 Interest rate options — 252 10 262 — 96 5 101 Interest rate futures and forward commitments — 10 — 10 — 4 — 4 Other contracts 1 38 1 40 2 70 — 72 Total derivative assets $ 1 $ 704 $ 11 $ 716 $ 2 $ 363 $ 5 $ 370 Derivative liabilities: Interest rate swaps $ — $ 157 $ — $ 157 $ — $ 237 $ — $ 237 Interest rate options — 10 — 10 — 20 — 20 Interest rate futures and forward commitments — 19 — 19 — 9 — 9 Other contracts 1 48 5 54 2 69 3 74 Total derivative liabilities $ 1 $ 234 $ 5 $ 240 $ 2 $ 335 $ 3 $ 340 Non-recurring fair value measurements Loans held for sale $ — $ — $ 14 $ 14 $ — $ — $ 10 $ 10 Foreclosed property and other real estate — 21 26 47 — 16 3 19 _________ (1) All following disclosures related to Level 3 recurring and non-recurring assets do not include those deemed to be immaterial. Assets and liabilities in all levels could result in volatile and material price fluctuations. Realized and unrealized gains and losses on Level 3 assets represent only a portion of the risk to market fluctuations in Regions’ consolidated balance sheets. Further, derivatives included in Levels 2 and 3 are used by ALCO in a holistic approach to managing price fluctuation risks. The following tables illustrate rollforwards for all material assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the three and six months ended June 30, 2019 and 2018 , respectively.

RECURRING FAIR VALUE MEASUREMENTS USING SIGNIFICANT UNOBSERVABLE INPUTS Residential mortgage servicing rights The significant unobservable inputs used in the fair value measurement of residential MSRs are OAS and CPR. This valuation requires generating cash flow projections over multiple interest rate scenarios and discounting those cash flows at a risk-adjusted rate. Additionally, the impact of prepayments and changes in the OAS are based on a variety of underlying inputs including servicing costs. Increases or decreases to the underlying cash flow inputs will have a corresponding impact on the value of the MSR asset. The net change in unrealized gains (losses) included in earnings related to MSRs held at period end are disclosed as the changes in valuation inputs or assumptions included in the MSR rollforward table in Note 4. See Note 4 for these amounts and additional disclosures related to assumptions used in the fair value calculation for MSRs. FAIR VALUE OPTION Regions has elected the fair value option for all FNMA and FHLMC eligible residential mortgage loans and certain commercial mortgage loans originated with the intent to sell. These elections allow for a more effective offset of the changes in fair values of the loans and the derivative instruments used to economically hedge them without the burden of complying with the requirements for hedge accounting. Regions has not elected the fair value option for other loans held for sale primarily because they are not economically hedged using derivative instruments. Fair values of residential mortgage loans held for sale are 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 values and market conditions, and are recorded in loans held for sale in the consolidated balance sheets. The following table summarizes the difference between the aggregate fair value and the aggregate unpaid principal balance for mortgage loans held for sale measured at fair value: June 30, 2019 December 31, 2018 Aggregate Fair Value Aggregate Unpaid Principal Aggregate Fair Value Less Aggregate Unpaid Principal Aggregate Fair Value Aggregate Unpaid Principal Aggregate Fair Value Less Aggregate Unpaid Principal (In millions) Mortgage loans held for sale, at fair value $ 433 $ 418 $ 15 $ 251 $ 242 $ 9 Interest income on mortgage loans held for sale is recognized based on contractual rates and is reflected in interest income on loans held for sale in the consolidated statements of income. The following table details net gains and losses resulting from changes in fair value of these loans, which were recorded in mortgage income in the consolidated statements of income during the three and six months ended June 30, 2019 and 2018 . These changes in fair value are mostly offset by economic hedging activities. An immaterial portion of these amounts was attributable to changes in instrument-specific credit risk.

Segment Reporting [Abstract]
Business Segment Information	BUSINESS SEGMENT INFORMATION Each of Regions’ reportable segments is a strategic business unit that serves specific needs of Regions’ customers based on the products and services provided. The segments are based on the manner in which management views the financial performance of the business. The Company has three reportable segments: Corporate Bank, Consumer Bank, and Wealth Management, with the remainder split between Discontinued Operations and Other. Additional information about the Company's reportable segments is included in Regions' Annual Report on Form 10-K for the year ended December 31, 2018. The application and development of management reporting methodologies is a dynamic process and is subject to periodic enhancements. As these enhancements are made, financial results presented by each reportable segment may be periodically revised. Discontinued operations includes all brokerage and investment activities associated with the sale of Morgan Keegan which closed on April 2, 2012, as well as the sale of Regions Insurance Group, Inc. and related affiliates, which closed on July 2, 2018. See Note 3 "Discontinued Operations" to the consolidated financial statements in the Annual Report on Form 10-K for the year ended December 31, 2018 for further discussion. The following tables present financial information for each reportable segment for the period indicated.

Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies and Guarantees	COMMITMENTS, CONTINGENCIES AND GUARANTEES COMMERCIAL COMMITMENTS Regions issues off-balance sheet financial instruments in connection with lending activities. The credit risk associated with these instruments is essentially the same as that involved in extending loans to customers and is subject to Regions’ normal credit approval policies and procedures. Regions measures inherent risk associated with these instruments by recording a reserve for unfunded commitments based on an assessment of the likelihood that the guarantee will be funded and the creditworthiness of the customer or counterparty. Collateral is obtained based on management’s assessment of the creditworthiness of the customer. Credit risk associated with these instruments is represented by the contractual amounts indicated in the following table: June 30, 2019 December 31, 2018 (In millions) Unused commitments to extend credit $ 52,305 $ 51,406 Standby letters of credit 1,396 1,428 Commercial letters of credit 124 44 Liabilities associated with standby letters of credit 22 28 Assets associated with standby letters of credit 24 29 Reserve for unfunded credit commitments 50 51 Unused commitments to extend credit —To accommodate the financial needs of its customers, Regions makes commitments under various terms to lend funds to consumers, businesses and other entities. These commitments include (among others) credit card and other revolving credit agreements, term loan commitments and short-term borrowing agreements. Many of these loan commitments have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of these commitments are expected to expire without being funded, the total commitment amounts do not necessarily represent future liquidity requirements. Standby letters of credit —Standby letters of credit are also issued to customers, which commit Regions to make payments on behalf of customers if certain specified future events occur. Regions has recourse against the customer for any amount required to be paid to a third party under a standby letter of credit. Historically, a large percentage of standby letters of credit expire without being funded. The contractual amount of standby letters of credit represents the maximum potential amount of future payments Regions could be required to make and represents Regions’ maximum credit risk. Commercial letters of credit —Commercial letters of credit are issued to facilitate foreign or domestic trade transactions for customers. As a general rule, drafts will be drawn when the goods underlying the transaction are in transit. LEGAL CONTINGENCIES Regions and its subsidiaries are subject to loss contingencies related to litigation, claims, investigations and legal and administrative cases and proceedings arising in the ordinary course of business. Regions evaluates these contingencies based on information currently available, including advice of counsel. Regions establishes accruals for those matters when a loss contingency is considered probable and the related amount is reasonably estimable. Any accruals are periodically reviewed and may be adjusted as circumstances change. Some of Regions' exposure with respect to loss contingencies may be offset by applicable insurance coverage. In determining the amounts of any accruals or estimates of possible loss contingencies however, Regions does not take into account the availability of insurance coverage. To the extent that Regions has an insurance recovery, the proceeds are recorded in the period the recovery is received. In addition, Regions has agreed to indemnify Raymond James for all legal matters resulting from pre-closing activities in conjunction with the sale of Morgan Keegan and recorded an indemnification obligation at fair value in the second quarter of 2012. When it is practicable, Regions estimates possible loss contingencies, whether or not there is an accrued probable loss. When Regions is able to estimate such possible losses, and when it is reasonably possible Regions could incur losses in excess of amounts accrued, Regions discloses the aggregate estimation of such possible losses. Regions currently estimates that it is reasonably possible that it may experience losses in excess of what Regions has accrued in an aggregate amount of up to approximately $20 million as of June 30, 2019, with it also being reasonably possible that Regions could incur no losses in excess of amounts accrued. However, as available information changes, the matters for which Regions is able to estimate, as well as the estimates themselves will be adjusted accordingly. The reasonably possible estimate includes legal contingencies that are subject to the indemnification agreement with Raymond James. Assessments of litigation and claims exposure are difficult because they involve inherently unpredictable factors including, but not limited to, the following: whether the proceeding is in the early stages; whether damages are unspecified, unsupported, or uncertain; whether there is a potential for punitive or other pecuniary damages; whether the matter involves legal uncertainties, including novel issues of law; whether the matter involves multiple parties and/or jurisdictions; whether discovery has begun or is not complete; whether meaningful settlement discussions have commenced; and whether the lawsuit involves class allegations. Assessments of class action litigation, which is generally more complex than other types of litigation, are particularly difficult, especially in the early stages of the proceeding when it is not known whether a class will be certified or how a potential class, if certified, will be defined. As a result, Regions may be unable to estimate reasonably possible losses with respect to some of the matters disclosed below, and the aggregated estimated amount discussed above may not include an estimate for every matter disclosed below. Regions is involved in formal and informal information-gathering requests, investigations, reviews, examinations and proceedings by various governmental regulatory agencies, law enforcement authorities and self-regulatory bodies regarding Regions’ business, Regions' business practices and policies, and the conduct of persons with whom Regions does business. Additional inquiries will arise from time to time. In connection with those inquiries, Regions receives document requests, subpoenas and other requests for information. The inquiries, including the one described below, could develop into administrative, civil or criminal proceedings or enforcement actions that could result in consequences that have a material effect on Regions' consolidated financial position, results of operations or cash flows as a whole. Such consequences could include adverse judgments, findings, settlements, penalties, fines, orders, injunctions, restitution, or alterations in our business practices, and could result in additional expenses and collateral costs, including reputational damage. Regions is cooperating with an investigation by the United States Attorney’s Office for the Eastern District of New York pertaining to Regions' banking relationship with a former customer and accounts maintained by related entities and individuals affiliated with the customer who may be involved in criminal activity, as well as related aspects of Regions' Anti-Money Laundering and Bank Secrecy Act compliance program. While the final outcome of litigation and claims exposures or of any inquiries is inherently unpredictable, management is currently of the opinion that the outcome of pending and threatened litigation and inquiries will not have a material effect on Regions’ business, consolidated financial position, results of operations or cash flows as a whole. However, in the event of unexpected future developments, it is reasonably possible that an adverse outcome in any of the matters discussed above could be material to Regions’ business, consolidated financial position, results of operations or cash flows for any particular reporting period of occurrence. GUARANTEES INDEMNIFICATION OBLIGATION As discussed in Note 3 in the Annual Report on Form 10-K for the year ended December 31, 2018, on April 2, 2012 (“Closing Date”), Regions closed the sale of Morgan Keegan and related affiliates to Raymond James. In connection with the sale, Regions agreed to indemnify Raymond James for all legal matters related to pre-closing activities, including matters filed subsequent to the Closing Date that relate to actions that occurred prior to closing. Losses under the indemnification include legal and other expenses, such as costs for judgments, settlements and awards associated with the defense and resolution of the indemnified matters. The maximum potential amount of future payments that Regions could be required to make under the indemnification is indeterminable due to the indefinite term of some of the obligations. As of June 30, 2019 , the carrying value and fair value of the indemnification obligation were immaterial. FANNIE MAE DUS LOSS SHARE GUARANTEE Regions is a DUS lender. The DUS program provides liquidity to the multi-family housing market. Regions services loans sold to Fannie Mae and is required to provide a loss share guarantee equal to one-third of the majority of its DUS servicing portfolio. At both June 30, 2019 and December 31, 2018 , the Company's DUS servicing portfolio totaled approximately $3.6 billion . Regions' maximum quantifiable contingent liability related to its loss share guarantee was approximately $1.2 billion at both June 30, 2019 and December 31, 2018 . The Company would be liable for this amount only if all of the loans it services for Fannie Mae, for which the Company retains some risk of loss, were to default and all of the collateral underlying these loans was determined to be without value at the time of settlement. Therefore, the maximum quantifiable contingent liability is not representative of the actual loss the Company would be expected to incur. The estimated fair value of the associated loss share guarantee recorded as a liability on the Company's consolidated balance sheets was approximately $5 million at June 30, 2019 and $4 million at December 31, 2018 . Refer to Note 1 "Summary of Significant Accounting Policies" to the consolidated financial statements in the Annual Report on Form 10-K for the year ended December 31, 2018, for additional information.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS Standard Description Required Date of Adoption Effect on Regions' financial statements or other significant matters Standards Adopted (or partially adopted) in 2019 ASU 2016-02, Leases ASU 2018-20, Narrow-Scope Improvements for Lessors ASU 2019-01, Codification Improvements This ASU creates ASC Topic 842, Leases, and supersedes Topic 840, Leases. The new guidance requires lessees to record a right-of-use asset and a corresponding liability equal to the present value of future rental payments on their balance sheets for all leases with a term greater than one year. There are not significant changes to lessor accounting; however, there were certain improvements made to align lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers. This guidance expands both quantitative and qualitative required disclosures. January 1, 2019 Regions adopted the standard on January 1, 2019 using the optional transition method, which allowed for a modified retrospective method of adoption with an immaterial cumulative effect adjustment to retained earnings without restating comparable periods. Regions elected the relief package of practical expedients for which there is no requirement to reassess existence of leases, their classification, and initial direct costs. Regions also applied the exemption for short-term leases with a term of less than one year, whereby Regions does not recognize a lease liability or right-of-use asset on the balance sheet but instead recognizes lease payments as an expense over the lease term as appropriate. For property leases, Regions did not elect the practical expedient to combine lease and non-lease components. The standard resulted in recognition of right-of-use assets and lease liabilities for operating leases, while accounting for finance leases remains largely unchanged. Adoption of the standard resulted in the recognition of additional right-of-use assets and lease liabilities for operating leases of approximately $451 million as of January 1, 2019. Operating lease right-of-use assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As most leases do not state an implicit rate, Regions utilizes the incremental borrowing rate based on information available at the commencement date to determine the present value of the lease payments. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the option will be exercised. Lease expenses are recognized on a straight-line basis over the lease term. ASU 2017-08, Receivables- Nonrefundable Fees and Other Costs This ASU amends Subtopic 310-20, Receivables-Nonrefundable Fees and Other Costs, to shorten the amortization period for certain purchased callable debt securities held at a premium to the earliest call date. Current guidance generally requires entities to amortize a premium as a yield adjustment over the contractual life of the instrument. Shortening the amortization period is generally expected to more closely align the recognition of interest income with expectations incorporated into the pricing of the underlying securities. The amendments do not affect the accounting treatment of discounts. This ASU should be adopted on a modified retrospective basis. January 1, 2019 The adoption of this guidance did not have a material impact. ASU 2018-07, This ASU amends and expands the scope of Topic 718, Compensation-Stock Compensation, to include share-based payment transactions for acquiring goods and services for non-employees. Under this guidance, the accounting for share-based payments to non-employees and employees will be substantially aligned. The measurement of equity-classified non-employee awards will now be fixed at the grant date. January 1, 2019 The adoption of this guidance did not have a material impact. ASU 2018-09, Codification Improvements The FASB issued this ASU to clarify, improve, and correct errors in the Codification. The ASU covers nine amendments, which affect a wide variety of Topics including business combinations, debt, derivatives and hedging, and defined contribution pension plans. Some amendments do not require transition guidance and are effective upon issuance, while others will be applicable for Regions starting in 2019. January 1, 2019 The adoption of this guidance did not have a material impact. ASU 2018-16, Derivatives and Hedging This ASU amends Topic 815, Derivatives and Hedging, to expand the list of U.S. benchmark interest rates permitted in applying hedge accounting. The amendments permit all entities that elect to apply hedge accounting to benchmark interest rate hedges under ASC 815, Derivatives and Hedging, to use the OIS rate based on the SOFR as a U.S. benchmark interest rate in addition to the four eligible U.S. benchmark interest rates. The amendments should be applied prospectively for qualifying new or redesignated hedging relationships entered into on or after the date of adoption. January 1, 2019 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 2016-13, Measurement of Credit Losses on Financial Instruments ASU 2018-19, Codification Improvements to Topic 326 ASU 2019-04, Codification Improvements to Topic 326 ASU 2019-05, Targeted Transition Relief to Topic 326 This ASU amends Topic 326, Financial Instruments- Credit Losses to replace the current incurred loss accounting model with a current expected credit loss approach (CECL) for financial instruments measured at amortized cost and other commitments to extend credit. The amendments require entities to consider all available relevant information when estimating current expected credit losses, including details about past events, current conditions, and reasonable and supportable forecasts. The resulting allowance for credit losses is to reflect the portion of the amortized cost basis that the entity does not expect to collect. The amendments also eliminate the current accounting model for purchased credit impaired loans and debt securities. Additional quantitative and qualitative disclosures are required upon adoption. January 1, 2020 Early adoption is permitted. Regions’ cross-functional implementation team, which is co-led by Finance and Risk Management, has developed a project plan that results in running a CECL parallel production during 2019 and the adoption of the standard in the first quarter of 2020. Key project implementation activities for 2019 include finalization of models, the qualitative framework, and the production process; completion of documentation, policies and disclosures; development of supporting analytics; and process and control testing. The project implementation plan establishes a parallel processing timeline which began with a limited parallel run in the first quarter of 2019. Parallel runs will be enhanced throughout the year. The second quarter parallel run included enhanced analytics, the qualitative framework and a parallel governance/decisioning process. A suite of controls including governance, data, forecast and model controls is in place to support the parallel process. Controls will continually be challenged and enhanced throughout the remainder of 2019, specifically regarding the precision of the controls and enhanced documentation. Regions provides updates to senior management and to the Audit Committee and Risk Committee of the Board of Directors. These communications provide an update on the status of the implementation as discussed above. Regions expects that the allowance for credit losses of $903 million may increase by approximately $400 million to $600 million upon adoption. This estimate is based on March 31, 2019 loan exposure balances and Regions' internally developed macroeconomic forecast, which provides for a relatively stable macroeconomic environment over a two year reasonable and supportable forecast period. Regions currently utilizes a two year reasonable and supportable forecast period for all portfolio segments which closely aligns with other internal forecast periods. After the forecast period, the Company reverts to longer term historical loss experience, adjusted for prepayments, to estimate losses over the remaining life. The estimated increase in the allowance is primarily the result of significant increases within residential first mortgage, home equity lending, consumer credit card and indirect- other consumer loan classes. Residential first mortgage and home equity lending products are impacted by having the longest time to maturity. Additionally, home equity lines of credit have the majority of future principal payment resets not beginning until 2023 and beyond with nearly 50% of the portfolio in a second lien position. Both consumer credit card and a significant portion of the indirect-other loan classes are unsecured. Regions' credit card accounts are primarily revolving, as opposed to accounts in which customers pay off their balances monthly. The disclosed estimate is subject to change based on continuing review and challenge of the models, assumptions, methodologies and judgments. The impact at adoption will also be influenced by the loan portfolio composition and quality at the adoption date, as well as, macroeconomic conditions and forecasts at that time. The impact will be reflected as an adjustment to beginning retained earnings, net of income taxes, at adoption. Federal banking regulatory agencies have provided relief for an initial capital decrease at adoption by allowing the impact to be phased-in over four years on a straight-line basis. The adoption of CECL in 2020 will also impact Regions' ongoing earnings, perhaps materially. Regions expects no material allowance on held to maturity securities because most of this portfolio consists of agency-backed securities that inherently have an immaterial risk of loss. Additionally, Regions expects no material impact to available for sale securities. Standard Description Required Date of Adoption Effect on Regions' financial statements or other significant matters Standards Not Yet Adopted ASU 2017-04, Simplifying the Test for Goodwill Impairment This ASU amends Topic 350, Intangibles-Goodwill and Other, and eliminates Step 2 from the goodwill impairment test. January 1, 2020 Early adoption is permitted. Regions believes the adoption of this guidance will not have a material impact. Regions does not plan to early adopt. ASU 2018-15, Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement This ASU amends Topic 350-40, Intangibles-Goodwill and Other-Internal-Use Software, regarding a customer's accounting for implementation, set-up, and other upfront costs incurred in a cloud computing arrangement that is hosted by the vendor, i.e. a service contract. Customers will apply the same criteria for capitalizing implementation costs as they would for an arrangement that has a software license. The amendments also prescribe the balance sheet, income statement, and cash flow classification of the capitalized implementation costs and related amortization expense, and require additional quantitative and qualitative disclosures. January 1, 2020 Early adoption is permitted. Regions believes the adoption of this guidance will not have a material impact. Regions does not plan to early adopt. ASU 2018-17, Targeted Improvements to Related Party Guidance for Variable Interest Entities This ASU amends Topic 810, Consolidation, guidance on how all reporting entities evaluate indirect interests held through related parties in common control arrangements when determining whether fees paid to decision makers and service providers are variable interests. January 1, 2020 Early adoption is permitted. Regions believes the adoption of this guidance will not have a material impact. Regions does not plan to early adopt. ASU 2019-04, Codification Improvements to Topics 815 and 825 This ASU amends Topic 815, Derivatives and Hedging, by providing clarification on ASU 2017-12, which the Company previously adopted. The amendment provides clarity on the term used to measure the change in fair value on a partial term hedge of interest rate risk. The amendment also provides additional guidance on the amortization of the basis adjustment on partial term hedges. This ASU also amends Topic 825, Financial Instruments, by providing clarification on ASU 2016-01, which the Company previously adopted. The amendment clarifies that an entity must remeasure a security without a readily determinable fair value at fair value in accordance with Topic 820 when an orderly transaction is identified for an identical or similar investment. January 1, 2020 Early adoption is permitted. Regions believes the adoption of this guidance will not have a material impact. Regions does not plan to early adopt.

[2]	Derivatives in a gain position are recorded as other assets and derivatives in a loss position are recorded as other liabilities on the consolidated balance sheets. There is no fair value presented for contracts that are characterized as settled daily.
[3]	Excluded from this table is the capital lease carrying amount of $1.2 billion at June 30, 2019 .
[4]	The estimated fair value of portfolio loans assumes sale of the loans to a third-party financial investor. Accordingly, the value to the Company if the loans were held to maturity is not reflected in the fair value estimate. In the current whole loan market, financial investors are generally requiring a higher rate of return than the return inherent in loans if held to maturity. The fair value discount on the loan portfolio's net carrying amount at June 30, 2019 was $320 million or 0.4 percent.

[9]	Estimated fair values are consistent with an exit price concept. The assumptions used to estimate the fair values are intended to approximate those that a market participant would use in a hypothetical orderly transaction. In estimating fair value, the Company makes adjustments for estimated changes in interest rates, market liquidity and credit spreads in the periods they are deemed to have occurred.
