Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	BASIS OF PRESENTATION Regions Financial Corporation (“Regions” or the "Company”) provides a full range of banking and bank-related services to individual and corporate customers through its subsidiaries and branch offices located across the South, Midwest and Texas. The Company competes with other financial institutions located in the states in which it operates, as well as other adjoining states. Regions is subject to the regulations of certain government agencies and undergoes periodic examinations by certain regulatory authorities. The accounting and reporting policies of Regions and the methods of applying those policies that materially affect the consolidated financial statements conform with GAAP and with general financial services industry practices. The accompanying interim financial statements have been prepared in accordance with the instructions for Form 10-Q and, therefore, do not include all information and notes to the consolidated financial statements necessary for a complete presentation of financial position, results of operations, comprehensive income and cash flows in conformity with GAAP. In the opinion of management, all adjustments, consisting of normal and recurring items, necessary for the fair presentation of the consolidated financial statements have been included. These interim financial statements should be read in conjunction with the consolidated financial statements and notes thereto in Regions’ Annual Report on Form 10-K for the year ended December 31, 2015 . Regions has evaluated all subsequent events for potential recognition and disclosure through the filing date of this Form 10-Q. On January 11, 2012, Regions entered into an agreement to sell Morgan Keegan and related affiliates. The transaction closed on April 2, 2012. See Note 2 and Note 14 for further details. Results of operations for the entities sold are presented separately as discontinued operations for all periods presented on the consolidated statements of income. This presentation is consistent with the consolidated financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2015 . During the fourth quarter of 2015, Regions reclassified its investments in FRB and FHLB stock from securities available for sale to other earning assets on its consolidated balance sheets. This reclassification has been made for all periods presented. Certain other prior period amounts have also been reclassified to conform to the current period presentation. These reclassifications are immaterial and have no effect on net income, comprehensive income, total assets, or total stockholders’ equity as previously reported.

The decrease in the number of securities and the total amount of unrealized losses from year-end 2015 was primarily due to changes in 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 other-than-temporary impairment 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 other-than-temporary impairments, management did identify a limited number of positions where an other-than-temporary impairment was believed to exist as of June 30, 2016 . Such impairments were related to available for sale equity securities with current market values below the highest traded price in the last six months. For the six months ended June 30, 2016 , such impairments totaled $1 million , and have been reflected as a reduction of net securities gains (losses) on the consolidated statements of income. Gross realized gains and gross realized losses on sales of securities available for sale, as well as other-than-temporary impairment losses, 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, 2016 December 31, 2015 (In millions, net of unearned income) Commercial and industrial $ 36,124 $ 35,821 Commercial real estate mortgage—owner-occupied 7,193 7,538 Commercial real estate construction—owner-occupied 344 423 Total commercial 43,661 43,782 Commercial investor real estate mortgage 4,302 4,255 Commercial investor real estate construction 2,660 2,692 Total investor real estate 6,962 6,947 Residential first mortgage 13,164 12,811 Home equity 10,832 10,978 Indirect—vehicles 4,159 3,984 Indirect—other consumer 722 545 Consumer credit card 1,113 1,075 Other consumer 1,089 1,040 Total consumer 31,079 30,433 $ 81,702 $ 81,162 During the three months ended June 30, 2016 and 2015 , Regions purchased approximately $300 million and $291 million , respectively, in indirect-vehicles and indirect-other consumer loans from third parties. During the six months ended June 30, 2016 and 2015, the comparable loan purchase amounts were approximately $579 million and $547 million , respectively. At June 30, 2016 , $14.6 billion in securities and net eligible loans held by Regions were pledged to secure current and potential borrowings from the FHLB. At June 30, 2016 , an additional $31.5 billion in net eligible loans held by Regions were pledged to the Federal Reserve Bank for potential borrowings. ALLOWANCE FOR CREDIT LOSSES Regions determines the appropriate level of the allowance on at least 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, 2015 , 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, 2016 and 2015 . The total allowance for loan losses and the related loan portfolio ending balances as of June 30, 2016 and 2015 , 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 loan 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. 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 loan 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 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 the loan portfolio segments and classes, excluding loans held for sale, as of June 30, 2016 , and December 31, 2015 . Commercial and investor real estate loan 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 which 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 which 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.

Similarly, Regions works to meet the individual needs of consumer borrowers to stem foreclosure through its CAP program. Refer to Note 6 "Allowance For Credit Losses" in the 2015 Annual Report on Form 10-K for additional information regarding the Company's TDRs. None of the modified consumer loans listed in the following TDR disclosures were collateral-dependent at the time of modification. At June 30, 2016 , approximately $38 million in residential first mortgage TDRs were in excess of 180 days past due and were considered collateral-dependent. At June 30, 2016 , approximately $4 million in home equity first lien TDRs were in excess of 180 days past due and approximately $5 million in home equity second lien TDRs were in excess of 120 days past due, both of which were considered collateral-dependent. Further discussion related to TDRs, including their impact on the allowance for loan losses and designation of TDRs in periods subsequent to the modification is included in Note 1 "Summary of Significant Accounting Policies" in the 2015 Annual Report on Form 10-K. The following tables present the end of period balance for loans modified in a TDR during the periods presented by portfolio segment and class, and the financial impact of those modifications. The tables include modifications made to new TDRs, as well as renewals of existing TDRs. The end of period balance, for the period in which it was added, of total loans first reported as new TDRs totaled approximately $211 million and $154 million for the six months ended June 30, 2016 and 2015 , respectively.

At June 30, 2016 , approximately $38 million of commercial and investor real estate loans modified in a TDR during the three months ended June 30, 2016 were on non-accrual status. Approximately 8.9 percent of this amount was 90 days past due. At June 30, 2016 , Regions had restructured binding unfunded commitments totaling $50 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 2016 2015 2016 2015 (In millions) Carrying value, beginning of period $ 239 $ 239 $ 252 $ 257 Additions 8 12 39 19 Increase (decrease) in fair value (1) : Due to change in valuation inputs or assumptions (22 ) 28 (58 ) 11 Economic amortization associated with borrower repayments (9 ) (11 ) (17 ) (19 ) Carrying value, end of period $ 216 $ 268 $ 216 $ 268 ________ (1) "Economic amortization associated with borrower repayments" includes both total loan payoffs as well as partial paydowns. On February 29, 2016, the Company completed a transaction to purchase the rights to service approximately $2.6 billion in residential mortgage loans. The residential MSRs asset was increased by the purchase price of approximately $24 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 2016 2015 (Dollars in millions) Unpaid principal balance $ 27,360 $ 26,637 Weighted-average prepayment speed (CPR; percentage) 16.5 % 10.0 % Estimated impact on fair value of a 10% increase $ (12 ) $ (15 ) Estimated impact on fair value of a 20% increase $ (24 ) $ (27 ) Option-adjusted spread (basis points) 999 998 Estimated impact on fair value of a 10% increase $ (8 ) $ (11 ) Estimated impact on fair value of a 20% increase $ (15 ) $ (21 ) Weighted-average coupon interest rate 4.3 % 4.4 % Weighted-average remaining maturity (months) 279 279 Weighted-average servicing fee (basis points) 27.8 27.8 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 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 includes 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 2016 2015 2016 2015 (In millions) Servicing related fees and other ancillary income $ 22 $ 20 $ 42 $ 41 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 On July 18, 2014, Regions was approved as a Fannie Mae DUS lender and acquired a DUS servicing portfolio totaling approximately $1.0 billion . The Fannie Mae DUS program provides liquidity to the multi-family housing market. As part of the transaction, Regions recorded $12 million in commercial MSRs and $15 million in intangible assets associated with the DUS license purchased. Regions also assumed a loss share guarantee associated with the purchased portfolio and any future originations. Regions estimated the fair value of the loss share guarantee to be approximately $4 million . See Note 1 "Summary of Significant Accounting Policies" in the 2015 Annual Report on Form 10-K for additional information. Also see Note 14 for additional information related to the guarantee. As of June 30, 2016 and December 31, 2015 , the DUS servicing portfolio was approximately $1.6 billion and $1.2 billion , respectively. The related commercial MSRs were valued at approximately $26 million and $16 million at June 30, 2016 and December 31, 2015 , respectively. The loss share guarantee was valued at approximately $3 million at both June 30, 2016 and December 31, 2015 .

Goodwill	GOODWILL Goodwill allocated to each reportable segment (each a reporting unit) is presented as follows: June 30, 2016 December 31, 2015 (In millions) Corporate Bank $ 2,452 $ 2,305 Consumer Bank 1,978 2,095 Wealth Management 452 478 $ 4,882 $ 4,878 Regions evaluates each reporting unit’s goodwill for impairment on an annual basis in the fourth quarter, or more often if events or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. A detailed description of the Company’s methodology and valuation approaches used to determine the estimated fair value of each reporting unit is included in the consolidated financial statements of the Annual Report on Form 10-K for the year ended December 31, 2015. Adverse changes in the economic environment, declining operations, or other factors could result in a decline in the implied fair value of goodwill. During the second quarter of 2016, Regions assessed events and circumstances for all three reporting units as of June 30, 2016, and through the date of the filing of this Quarterly Report on Form 10-Q that could potentially indicate goodwill impairment. The indicators assessed included: • 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. During the first quarter of 2016, Regions reorganized its internal management structure and, accordingly, its segment reporting structure. Due to the organizational realignment, Regions determined that quantitative testing of goodwill was required for all reporting units, and goodwill was reallocated to each reporting unit using a relative fair value approach. Results of the first quarter 2016 goodwill test indicated that the estimated fair value of each reporting unit exceeded its carrying amounts as of the test date. Additionally, after assessing the indicators noted above, Regions determined that it was not more likely than not that the fair value of each of its reporting units had declined below their carrying value as of June 30, 2016. Therefore, Regions determined that a test of goodwill impairment was not required for each of Regions’ reporting units for the June 30, 2016 interim period.

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 preferred stock. The Board of Directors declared $8 million in cash dividends on Series A Preferred Stock during the first and second quarters of both 2016 and 2015. Series B Preferred Stock dividends were $8 million for the first and second quarters of both 2016 and 2015. Prior to the first quarter of 2016, the Company was in a retained deficit position and preferred dividends were recorded as a reduction of preferred stock, including related surplus. During the first quarter of 2016, the Company achieved positive retained earnings and preferred dividends were recorded as a reduction of retained earnings. COMMON STOCK On June 29, 2016, Regions received no objection from the Federal Reserve to its 2016 capital plan that was submitted as part of the CCAR process. In addition to continuing the $0.065 quarterly common stock dividend, actions that Regions may undertake as outlined in its capital plan include the repurchase of up to $640 million in common shares. The capital plan also provides the potential for a dividend increase beginning in the second quarter of 2017, which is expected to be considered by the Board in early 2017. On July 14, 2016, Regions' Board authorized a new $640 million common stock repurchase plan, permitting repurchases from the beginning of the third quarter of 2016 through the second quarter of 2017. The Company began to repurchase shares under this plan in the third quarter of 2016, and as of August 4, 2016, Regions had repurchased approximately 9.4 million shares of common stock at a total cost of approximately $85.0 million . These shares were immediately retired and therefore are not included in treasury stock. On April 23, 2015, Regions' Board approved an increase of its quarterly common stock dividend to $0.06 per share effective with the quarterly dividend paid in July 2015. The Board also authorized a $875 million common stock repurchase plan, permitting repurchases from the beginning of the second quarter of 2015 through the end of the second quarter of 2016. Through June 30, 2016, Regions repurchased approximately 94.1 million shares of common stock at a total cost of approximately $875 million under this plan. The Company closed out this repurchase plan in the second quarter of 2016. These shares were immediately retired and therefore are not included in treasury stock. The Board declared a $0.065 per share cash dividend on common stock for the second quarter of 2016 , and a $0.06 per share cash dividend for the first quarter of 2016, totaling $0.125 per share cash dividend for the first six months of 2016. The Board declared a $0.06 per share cash dividend on common stock for the second quarter of 2015, and a $0.05 per share cash dividend for the first quarter of 2015, totaling $0.11 per share cash dividend for the first six months of 2015. Prior to the first quarter of 2016, the Company was in a retained deficit position and common stock dividends were recorded as a reduction of additional paid-in capital. During the first quarter of 2016, the Company achieved positive retained earnings and common stock dividends were recorded as a reduction of retained earnings.

For earnings (loss) per common share from discontinued operations, basic and diluted weighted-average common shares outstanding are the same for the three and six months ended June 30, 2015 due to a net loss. The effect from the assumed exercise of 30 million stock options for both the three and six months ended June 30, 2016 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. The effect from the assumed exercise of 30 million and 29 million stock options for the three and six months ended June 30, 2015 , respectively, 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.

The terms of all awards issued under these plans are determined by the Compensation Committee of the Board of Directors; however, no awards may be granted after the tenth anniversary from the date the plans were initially approved by stockholders. Incentive awards usually vest based on employee service, generally within three years from the date of the grant. The contractual lives of options granted under these plans are typically ten years from the date of the grant. On April 23, 2015, the stockholders of the Company approved the Regions Financial Corporation 2015 LTIP , which permits the Company to grant to employees and directors various forms of incentive compensation. These forms of incentive compensation are similar to the types of compensation approved in prior plans. The 2015 LTIP authorizes 60 million common share equivalents available for grant, where grants of options and grants of full value awards (e.g., shares of restricted stock, restricted stock units and performance stock units) count as one share equivalent. Unless otherwise determined by the Compensation Committee of the Board, grants of restricted stock, restricted stock units, and performance stock units accrue dividends, or their notional equivalent, as they are declared by the Board, and are paid upon vesting of the award. Upon adoption of the 2015 LTIP, Regions closed the prior long-term incentive plan to new grants, and, accordingly, prospective grants must be made under the 2015 LTIP or a successor plan. All existing grants under prior long-term incentive plans are unaffected by adoption of the 2015 LTIP. The number of remaining share equivalents available for future issuance under the 2015 LTIP was approximately 48 million at June 30, 2016 . STOCK OPTIONS The following table summarizes the activity related to stock options: Six Months Ended June 30 2016 2015 Number of Options Weighted-Average Exercise Price Number of Options Weighted-Average Exercise Price Outstanding at beginning of period 19,350,157 $ 21.06 25,316,676 $ 23.07 Exercised (227,492 ) 6.91 (291,460 ) 6.96 Forfeited or expired (3,819,783 ) 34.72 (5,301,942 ) 31.95 Outstanding at end of period 15,302,882 $ 17.86 19,723,274 $ 20.92 Exercisable at end of period 15,302,882 $ 17.86 19,723,274 $ 20.92 RESTRICTED STOCK AWARDS AND PERFORMANCE STOCK AWARDS Regions periodically grants restricted stock awards that vest upon service conditions. Regions also periodically grants restricted stock awards and performance stock awards that vest based upon service conditions and performance conditions. Incremental shares earned above the performance target associated with previous performance stock awards are included when and if performance targets are achieved. Dividend payments during the vesting period are deferred to the end of the vesting term. The fair value of these restricted shares, restricted stock units and performance stock units was estimated based upon the fair value of the underlying shares on the date of the grant. The valuation was not adjusted for the deferral of dividends.

Defined Benefit Pension Plans and Defined Benefit Postretirement Plans Disclosure [Abstract]
Pension and Other Postretirement Benefits	PENSION AND OTHER POSTRETIREMENT BENEFITS Regions has a defined benefit pension plan qualified under the Internal Revenue Code covering only certain employees as the pension plan is closed to new entrants. The Company also sponsors a SERP, which is a non-qualified pension plan that provides certain senior executive officers defined benefits in relation to their compensation. Net periodic pension cost, which is recorded in salaries and employee benefits on the consolidated statements of income, included the following components: Qualified Plan Non-qualified Plans Total Three Months Ended June 30 2016 2015 2016 2015 2016 2015 (In millions) Service cost $ 8 $ 10 $ 1 $ 2 $ 9 $ 12 Interest cost 18 21 2 2 20 23 Expected return on plan assets (36 ) (38 ) — — (36 ) (38 ) Amortization of actuarial loss 8 11 — 1 8 12 Amortization of prior service cost — — — — — — Net periodic pension cost (credit) $ (2 ) $ 4 $ 3 $ 5 $ 1 $ 9 Qualified Plan Non-qualified Plans Total Six Months Ended June 30 2016 2015 2016 2015 2016 2015 (In millions) Service cost $ 17 $ 20 $ 2 $ 3 $ 19 $ 23 Interest cost 36 42 3 3 39 45 Expected return on plan assets (72 ) (74 ) — — (72 ) (74 ) Amortization of actuarial loss 16 22 1 2 17 24 Amortization of prior service cost — — — — — — Net periodic pension cost (credit) $ (3 ) $ 10 $ 6 $ 8 $ 3 $ 18 On December 31, 2015, Regions changed the basis for determining the assumption used to estimate the service and interest components of net periodic pension costs for pension and other postretirement benefits. This change provides a more precise measurement of service and interest costs and resulted in an immaterial impact to the pension benefit obligation as of December 31, 2015. Additionally, Regions separated the Regions Financial Corporation Retirement Plan into two plans, effective January 1, 2016, creating a new plan primarily for participants who remained actively employed as of that date. The corresponding assets and liabilities of these participants will be transferred to the new plan in 2016. All other participants will remain in the existing plan. See Note 18 "Employee Benefit Plans" of the Annual Report on Form 10-K for the year ended December 31, 2015 for further discussion. Regions' policy for funding the qualified pension plan is to contribute annually at least the amount required by the IRS minimum funding standards. Regions made no contribution to the plan during the first six months of 2016. Regions also provides other postretirement benefits such as defined benefit health care plans and life insurance plans that cover certain retired employees. There was no material impact from other postretirement benefits on the consolidated financial statements for the six months ended June 30, 2016 or 2015 .

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, 2015 , 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, which includes long-term debt and certificates of deposit. 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 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. Regions issues long-term fixed-rate debt for various funding needs. Regions may enter into receive LIBOR/pay fixed forward starting swaps to hedge risks of changes in the projected quarterly interest payments attributable to changes in the benchmark interest rate (LIBOR) during the time leading up to the probable issuance date of the new long-term fixed-rate debt. Regions recognized an unrealized after-tax gain of $77 million and $18 million in accumulated other comprehensive income (loss) at June 30, 2016 and 2015 , respectively, related to terminated 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 $12 million and $11 million during the three months ended June 30, 2016 and 2015 , respectively, and pre-tax income of $24 million and $22 million during the six months ended June 30, 2016 and 2015 , respectively, related to the amortization of cash flow hedges of loan instruments. Regions expects to reclassify out of accumulated other comprehensive income (loss) and into earnings approximately $132 million in pre-tax income due to the receipt or payment of interest payments on all cash flow hedges within the next twelve months. Included in this amount is $36 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 nine years as of June 30, 2016 . The following tables present the effect of hedging derivative instruments on the consolidated statements of income: Gain or (Loss) Recognized in Income on Derivatives Location of Amounts Recognized in Income on Derivatives and Related Hedged Item Gain or (Loss) Recognized in Income on Related Hedged Item Three Months Ended June 30 Three Months Ended June 30 2016 2015 2016 2015 (In millions) (In millions) Fair Value Hedges: Interest rate swaps on: Debt/CDs $ 4 $ 4 Interest expense $ (1 ) $ 2 Debt/CDs 12 (3 ) Other non-interest expense (12 ) 3 Securities available for sale (2 ) (4 ) Interest income — — Securities available for sale (12 ) 25 Other non-interest expense 12 (25 ) Total $ 2 $ 22 $ (1 ) $ (20 ) Effective Portion (3) Gain or (Loss) Recognized in AOCI (1) Location of Amounts Reclassified from AOCI into Income Gain or (Loss) Reclassified from AOCI into Income (2) Three Months Ended June 30 Three Months Ended June 30 2016 2015 2016 2015 (In millions) (In millions) Cash Flow Hedges: Interest rate swaps $ 62 $ (25 ) Interest income on loans $ 35 $ 34 Total $ 62 $ (25 ) $ 35 $ 34 Gain or (Loss) Recognized in Income on Derivatives Location of Amounts Recognized in Income on Derivatives and Related Hedged Item Gain or (Loss) Recognized in Income on Related Hedged Item Six Months Ended June 30 Six Months Ended June 30 2016 2015 2016 2015 (In millions) (In millions) Fair Value Hedges: Interest rate swaps on: Debt/CDs $ 8 $ 8 Interest expense $ (2 ) $ 6 Debt/CDs 27 4 Other non-interest expense (27 ) (4 ) Securities available for sale (5 ) (8 ) Interest income — — Securities available for sale (38 ) 5 Other non-interest expense 37 (6 ) Total $ (8 ) $ 9 $ 8 $ (4 ) Effective Portion (3) Gain or (Loss) Recognized in AOCI (1) Location of Amounts Reclassified from AOCI into Income Gain or (Loss) Reclassified from AOCI into Income (2) Six Months Ended June 30 Six Months Ended June 30 2016 2015 2016 2015 (In millions) (In millions) Cash Flow Hedges: Interest rate swaps $ 203 $ 12 Interest income on loans $ 74 $ 67 Total $ 203 $ 12 $ 74 $ 67 ______ (1) After-tax (2) Pre-tax (3) All cash flow hedges were highly effective for all periods presented, and the change in fair value attributed to hedge ineffectiveness was not material. DERIVATIVES NOT DESIGNATED AS HEDGING INSTRUMENTS The Company holds a portfolio of interest rate swaps, option contracts, and futures and forward commitments that result from transactions with its commercial customers in which they manage their risks by entering into a derivative with Regions. 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 other) 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, 2016 and December 31, 2015 , Regions had $464 million and $322 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, 2016 and December 31, 2015 , Regions had $802 million and $666 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 and other. Regions has elected to account for residential MSRs at fair market 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 on its consolidated statements of income. As of June 30, 2016 and December 31, 2015 , the total notional amount related to these contracts was $5.3 billion and $3.6 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 three and six months ended June 30, 2016 and 2015 : Three Months Ended June 30 Six Months Ended June 30 Derivatives Not Designated as Hedging Instruments 2016 2015 2016 2015 (In millions) Capital markets fee income and other (1) : Interest rate swaps $ (1 ) $ 4 $ 3 $ 8 Interest rate options 4 4 14 4 Interest rate futures and forward commitments 2 — 3 (1 ) Other contracts 14 (11 ) 2 (7 ) Total capital markets fee income and other 19 (3 ) 22 4 Mortgage income: Interest rate swaps 19 (16 ) 48 (3 ) Interest rate options 3 (3 ) 8 4 Interest rate futures and forward commitments (1 ) 3 1 7 Total mortgage income 21 (16 ) 57 8 $ 40 $ (19 ) $ 79 $ 12 ______ (1) Capital markets fee income and other is included in Other income on the consolidated statements of income. Credit risk, defined as all positive exposures not collateralized with cash or other assets or reserved for, at June 30, 2016 and December 31, 2015 , totaled approximately $728 million and $406 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. Credit derivatives, 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 2016 and 2023. Credit derivatives whereby Regions has sold credit protection have maturities between 2016 and 2025. 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, 2016 was approximately $137 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, 2016 and 2015 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 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, 2016 and December 31, 2015 , were $199 million and $180 million , respectively, for which Regions had posted collateral of $201 million and $180 million , respectively, in the normal course of business. OFFSETTING Regions engages in derivatives transactions with dealers and customers. These derivatives transactions are subject to enforceable master netting agreements, which include a right of setoff by the non-defaulting or non-affected party upon early termination of the derivatives transaction. The following table presents the Company's gross derivative positions, including collateral posted or received, as of June 30, 2016 and December 31, 2015 . Offsetting Derivative Assets Offsetting Derivative Liabilities June 30, 2016 December 31, 2015 June 30, 2016 December 31, 2015 (In millions) Gross amounts subject to offsetting $ 955 $ 718 $ 727 $ 677 Gross amounts not subject to offsetting 315 108 218 81 Gross amounts recognized 1,270 826 945 758 Gross amounts offset in the consolidated balance sheets (1) 536 409 658 558 Net amounts presented in the consolidated balance sheets 734 417 287 200 Gross amounts not offset in the consolidated balance sheets: Financial instruments 4 5 51 50 Cash collateral received/posted 2 6 7 52 Net amounts $ 728 $ 406 $ 229 $ 98 ________ (1) At June 30, 2016 , gross amounts of derivative assets and liabilities offset in the consolidated balance sheets presented above include cash collateral received of $149 million and cash collateral posted of $270 million . At December 31, 2015 , gross amounts of derivative assets and liabilities offset in the consolidated balance sheets presented above include cash collateral received of $108 million and cash collateral posted of $256 million . Gross amounts of derivatives not subject to offsetting primarily consist of derivatives cleared through a Central Counterparty Clearing House and interest rate lock commitments to originate mortgage loans.

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, 2015 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. There were no such transfers during the six month periods ended June 30, 2016 and 2015 . Trading account securities and 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, 2016 and December 31, 2015 : June 30, 2016 December 31, 2015 Level 1 Level 2 Level 3 Total Estimated Fair Value Level 1 Level 2 Level 3 Total Estimated Fair Value (In millions) Recurring fair value measurements Trading account securities $ 117 $ — $ — $ 117 $ 110 $ — $ 33 $ 143 Securities available for sale: U.S. Treasury securities $ 240 $ — $ — $ 240 $ 228 $ — $ — $ 228 Federal agency securities — 216 — 216 — 218 — 218 Obligations of states and political subdivisions — 1 — 1 — 1 — 1 Mortgage-backed securities (MBS): Residential agency — 16,933 — 16,933 — 16,062 — 16,062 Residential non-agency — — 5 5 — — 5 5 Commercial agency — 3,243 — 3,243 — 3,018 — 3,018 Commercial non-agency — 1,183 — 1,183 — 1,231 — 1,231 Corporate and other debt securities — 1,412 3 1,415 — 1,664 3 1,667 Equity securities 258 — — 258 280 — — 280 Total securities available for sale $ 498 $ 22,988 $ 8 $ 23,494 $ 508 $ 22,194 $ 8 $ 22,710 Mortgage loans held for sale $ — $ 445 $ 30 $ 475 $ — $ 353 $ — $ 353 Residential mortgage servicing rights $ — $ — $ 216 $ 216 $ — $ — $ 252 $ 252 Derivative assets: Interest rate swaps $ — $ 1,118 $ — $ 1,118 $ — $ 610 $ — $ 610 Interest rate options — 3 17 20 — 1 10 11 Interest rate futures and forward commitments — 11 — 11 — 5 — 5 Other contracts 2 119 — 121 — 200 — 200 Total derivative assets $ 2 $ 1,251 $ 17 $ 1,270 $ — $ 816 $ 10 $ 826 Derivative liabilities: Interest rate swaps $ — $ 824 $ — $ 824 $ — $ 564 $ — $ 564 Interest rate options — 1 — 1 — 1 — 1 Interest rate futures and forward commitments — 17 — 17 — 6 — 6 Other contracts — 103 — 103 — 187 — 187 Total derivative liabilities $ — $ 945 $ — $ 945 $ — $ 758 $ — $ 758 Non-recurring fair value measurements Loans held for sale $ — $ — $ 38 $ 38 $ — $ — $ 36 $ 36 Foreclosed property and other real estate — 28 23 51 — 30 8 38 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 the Asset and Liability Management Committee of the Company in a holistic approach to managing price fluctuation risks. The following tables illustrate rollforwards for all 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, 2016 and 2015 . The tables do not reflect the change in fair value attributable to any related economic hedges the Company used to mitigate the interest rate risk associated with these assets and liabilities.

RECURRING FAIR VALUE MEASUREMENTS USING SIGNIFICANT UNOBSERVABLE INPUTS Trading account securities The fair value in this category relates to high yield corporate securities. Significant unobservable inputs include the spread to High Yield Index. A significant increase in this input would result in a significantly lower fair value measurement. Securities available for sale Mortgage-backed securities: residential non-agency —The fair value reported in this category relates to retained interests in legacy securitizations. Significant unobservable inputs include the spread to LIBOR, CPR, probability of default, and loss severity in the event of default. Significant increases in spread to LIBOR, probability of default and loss given default in isolation would result in significantly lower fair value. A significant increase in CPR in isolation would result in an increase to fair value. Corporate and other debt securities —Significant unobservable inputs include evaluated quotes on comparable bonds for the same issuer and management-determined comparability adjustments. Changes in the evaluated quote on comparable bonds would result in a directionally similar change in the fair value of the corporate and other debt securities. Commercial mortgage loans held for sale Commercial mortgage loans held for sale are 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. Significant unobservable inputs include credit spreads for bonds in the commercial mortgage backed securitizations. Residential mortgage servicing rights The significant unobservable inputs used in the fair value measurement of residential MSRs are OAS and prepayment speed. 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 such as 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 5. See Note 5 for these amounts and additional disclosures related to assumptions used in the fair value calculation for MSRs. Derivative assets Residential mortgage interest rate options —These instruments are interest rate lock agreements made in the normal course of originating residential mortgage loans. Significant unobservable inputs in the fair value measurement are OAS, prepayment speeds, and pull-through. The impact of OAS and prepayment speed inputs in the valuation of these derivative instruments are consistent with the MSR discussion above. Pull-through is an estimate of the number of interest rate lock commitments that will ultimately become funded loans. Increases or decreases in the pull-through assumption will have a corresponding impact on the value of these derivative assets. Commercial mortgage interest rate options —These instruments are interest rate lock agreements made in the normal course of originating commercial mortgage loans. The significant unobservable input in the fair value measurement using discounted cash flows is the internal rate of return. The Company's internal rates of return are compared against those of market competitors, and should those rates change the Company's rates would also change in a similar direction. NON-RECURRING FAIR VALUE MEASUREMENTS USING SIGNIFICANT UNOBSERVABLE INPUTS Loans held for sale Commercial loans held for sale are valued based on multiple data points indicating the fair value for each loan. The primary data point for loans held for sale is a discount to the appraised value of the underlying collateral, which considers the return required by potential buyers of the loans. Management establishes this discount or comparability adjustment based on recent sales of loans secured by similar property types. As liquidity in the market increases or decreases, the comparability adjustment and the resulting asset valuation are impacted. These non-recurring fair value measurements are typically recorded on the date an updated appraisal is received. Foreclosed property and other real estate Property in foreclosure is valued based on offered quotes as available. If no sales contract is pending for a specific property, management establishes a comparability adjustment to the appraised value based on historical activity considering proceeds for properties sold versus the corresponding appraised value. Increases or decreases in realization for properties sold impact the comparability adjustment for similar assets remaining on the balance sheet. These non-recurring fair value measurements are typically recorded on the date an updated offered quote or appraisal is received. Bank owned property available for sale is valued based on estimated third-party valuations utilizing recent sales data from similar transactions. A broker's opinion of value is obtained to further support the asset valuations. Updated valuations along with actual sales results of similar properties can further impact these values. These non-recurring fair value measurements are typically recorded on the date an updated third-party valuation is received. 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. Fair values of commercial mortgage loans held for sale are 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. 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, 2016 December 31, 2015 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 $ 475 $ 454 $ 21 $ 353 $ 341 $ 12 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 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, 2016 and 2015 . 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. During the first quarter of 2016, Regions reorganized its internal management structure and, accordingly, its segment reporting structure. Under the organizational realignment, Regions will continue to operate with the same three reporting units with the Relationship Management component of Business Banking moving to the Corporate Bank and the Branch Small Business component of Business Banking remaining part of the Consumer Bank. Previously, all of Business Banking was included within the Consumer Bank. The Wealth Management segment remained unchanged during the organizational realignment. Additionally, in prior years the provision for loan losses was allocated to each segment based on actual net charge-offs that had been recognized by the segment. During the first quarter of 2016, Regions began allocating the provision for loan losses to each segment using an estimated loss methodology with the difference between the consolidated provision for loan losses and the segments’ estimated loss reflected in Other. Lastly, allocations of operational and overhead cost pools among the segments were modified during the first quarter of 2016 to better align the total costs to support each segment in accordance with the reorganized management structure. Segment results for all periods presented have been recast to reflect this organizational realignment, as well as the provision for loan losses methodology change and the cost allocation modifications. Additional information about the Company's reportable segments is included in Regions' Annual Report on Form 10-K for the year ended December 31, 2015. 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. 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, 2016 December 31, 2015 (In millions) Unused commitments to extend credit $ 44,906 $ 45,516 Standby letters of credit 1,429 1,477 Commercial letters of credit 44 63 Liabilities associated with standby letters of credit 33 32 Assets associated with standby letters of credit 33 33 Reserve for unfunded credit commitments 64 52 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, its affiliates and subsidiaries, and current and former officers, directors and employees, are sometimes collectively referred to as Regions and certain Related Persons. 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, as previously discussed, 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. The indemnification obligation had a carrying amount of approximately $61 million and an estimated fair value of approximately $54 million as of June 30, 2016 (see Note 12). 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 any such losses in excess of amounts accrued, including legal contingencies that are subject to the indemnification agreement with Raymond James, would be immaterial to Regions' financial statements as a whole. However, as available information changes, the matters for which Regions is able to estimate, as well as the estimates themselves will be adjusted accordingly. 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. Beginning in December 2007, Regions and certain of its affiliates were named in class-action lawsuits filed in federal and state courts on behalf of investors who purchased shares of certain Regions Morgan Keegan Select Funds (the “Funds”) and stockholders of Regions. These class-action lawsuits have all been resolved among the parties. Court approvals for settlements in the open-end Funds class action and for the investors represented by the Trustee Ad Litem are being sought. Certain of the shareholders in these Funds and other interested parties have entered into arbitration proceedings and individual civil claims, in lieu of participating in the class actions. These lawsuits and proceedings are subject to the indemnification agreement with Raymond James discussed above. In July 2006, Morgan Keegan and a former Morgan Keegan analyst were named as defendants in a lawsuit filed by a Canadian insurance and financial services company and its American subsidiary in the Circuit Court of Morris County, New Jersey. Plaintiffs alleged civil claims under the RICO Act and claims for commercial disparagement, tortious interference with contractual relationships, tortious interference with prospective economic advantage and common law conspiracy. Plaintiffs allege that defendants engaged in a multi-year conspiracy to publish and disseminate false and defamatory information about plaintiffs to improperly drive down plaintiffs’ stock price, so that others could profit from short positions. Plaintiffs allege that defendants’ actions damaged their reputations and harmed their business relationships. Plaintiffs seek monetary damages for a number of categories of alleged damages, including lost insurance business, lost financings and increased financing costs, increased audit fees and directors and officers insurance premiums and lost acquisitions. In September 2012, the trial court dismissed the case with prejudice. Plaintiffs have filed an appeal. This matter is subject to the indemnification agreement with Raymond James. A previously dismissed shareholder derivative action was refiled in June 2015. The original action alleged mismanagement, waste of corporate assets, breach of fiduciary duty and unjust enrichment relating to bonuses and other benefits received by executive management. The named defendants filed an opposition to the action, and on April 5, 2016, the court dismissed the action with prejudice. On May 5, 2016, plaintiffs filed a motion asking the court to reconsider the dismissal, which was denied by the court on June 24, 2016. 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 those 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 has reached an agreement in principle on a settlement amount with the Department of Justice on behalf of HUD. This agreement resolves a previously disclosed regulatory inquiry regarding residential mortgage loan origination, underwriting and quality control practices for FHA insured loans made by Regions. The settlement, which is subject to final review and approval by the Department of Justice, will not have a material effect on Regions' consolidated financial position, results of operations or cash flows as a whole as Regions has previously established reserves to cover this matter. In September 2014, Regions received an investigative request from the Office of Inspector General of the Federal Housing Finance Agency regarding its residential mortgage loan origination, underwriting and quality control practices for loans Regions sold to Fannie Mae and Freddie Mac. Regions has fully cooperated with the inquiry, which is part of an industry-wide investigation. 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 2, 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. However, Regions expects the majority of ongoing legal matters to be resolved within approximately one to two years. As of the Closing Date, the fair value of the indemnification obligation, which includes defense costs and unasserted claims, was approximately $385 million , of which approximately $256 million was recognized as a reduction to the gain on sale of Morgan Keegan. The fair value was determined through the use of a present value calculation that takes into account the future cash flows that a market participant would expect to receive from holding the indemnification liability as an asset. Regions performed a probability-weighted cash flow analysis and discounted the result at a credit-adjusted risk free rate. The fair value of the indemnification liability includes amounts that Regions had previously determined meet the definition of probable and reasonably estimable. Adjustments to the indemnification obligation are recorded within professional and legal expenses within discontinued operations (see Note 2). As of June 30, 2016 , the carrying value of the indemnification obligation was approximately $61 million . FANNIE MAE DUS LOSS SHARE GUARANTEE Regions is a Fannie Mae DUS lender. The Fannie Mae 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 June 30, 2016 , and December 31, 2015 , the Company's DUS servicing portfolio totaled approximately $1.6 billion and $1.2 billion , respectively. Regions' maximum quantifiable contingent liability related to its loss share guarantee was approximately $484 million and $356 million at June 30, 2016 and December 31, 2015 , respectively. 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 balance sheet was approximately $3 million at June 30, 2016 , and December 31, 2015 . 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, 2015, for additional information.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS In August 2015, the FASB issued a standard that defers the effective date of the new revenue recognition standard, issued in May 2014, by one year. The new revenue recognition standard is discussed in the Annual Report on Form 10-K for the year ended December 31, 2014. The new guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early adoption is permitted as of the date of the original effective date, for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Regions is in the process of reviewing the potential impact the adoption of this guidance will have to its consolidated financial statements. In January 2016, the FASB issued accounting guidance on the recognition and measurement of financial assets and financial liabilities that supersedes existing guidance. The new guidance: (a) requires equity investments (except for those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in the fair value recognized through net income; (b) simplifies the impairment assessment of equity securities without readily determinable fair values by requiring a qualitative assessment to identify impairment; (c) eliminates the requirement for public business entities to disclose the method and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet; (d) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; (e) requires an entity to present separately in other comprehensive income, the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments; (f) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial assets on the balance sheet or the notes to the financial statements; and (g) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available for sale securities in combination with the entity’s other deferred tax assets. This guidance is effective for annual and interim periods beginning after December 15, 2017. Early adoption is not permitted except for the amendment related to separate presentation in other comprehensive income discussed above in (e). Entities should apply the amendments by means of cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity securities without readily determinable fair values (including disclosure requirements) should be applied prospectively to equity investments that exist as of the date of adoption. Regions is evaluating the impact to its consolidated financial statements upon adoption. In February 2016, the FASB issued accounting guidance intended to improve the understanding and comparability of financial statements by providing users with more information relating primarily to a lessee’s leasing activities. There are no significant changes expected to the income statement but lessees will be required 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. Management will also be required under the new guidance to make significant judgments regarding the likelihood of exercising lease renewal or extension options in order to determine the appropriate lease term and amount of future minimum lease payments. While the new guidance removes the current bright lines used to classify leases, the criteria are largely similar to current lease accounting. Additionally, the new standard substantially changes sale-leaseback accounting requiring the lessee to record a right-of-use asset and aligning sale criteria with revenue recognition guidance. This guidance expands both quantitative and qualitative required disclosures in order to provide financial statement users information on the timing, amount, and uncertainty of future cash flows from leases. The revised leasing guidance is effective for fiscal years and interim periods beginning after December 15, 2018, with early application permitted. Regions is evaluating the impact to its consolidated financial statements upon adoption. In March 2016, the FASB issued accounting guidance that clarifies and enhances the implementation guidance on principal versus agent considerations within the new revenue recognition standard . The amendments are as follows: (a) clarification regarding how an entity should identify the unit of accounting for the principal versus agent evaluation; (b) clarification regarding how the control principle applies to transactions such as service arrangements; (c) control indicators reframed to focus on evidence of a principal relationship rather than an agency relationship, as well as clarification added regarding the relationship between the control principle and the indicators; and (d) revisions to the examples presented in current guidance as well as the addition of new examples. The guidance is effective for annual and interim periods beginning after December 15, 2017. Regions is evaluating the impact to its consolidated financial statements upon adoption. In March 2016, the FASB issued new accounting guidance that addresses how a change in the counterparty to a derivative contract affects a hedging relationship. This guidance clarifies that a novation (defined as replacing one counterparty to a derivative instrument with a new counterparty) of a derivative contract does not, in and of itself, require dedesignation of a hedging relationship or represent a change in the critical terms of the hedge relationship so long as (a) all other hedge accounting criteria are still met, (b) the hedging relationship is expected to remain highly effective, and (c) there are no concerns about the collectability of the derivative’s cash flows (i.e. the creditworthiness of the new counterparty is similar to the one being replaced). The guidance is effective for annual and interim periods beginning after December 15, 2016 . The amendments may be applied prospectively or on a modified retrospective basis to all existing and new hedge accounting relationships in which a novation occurs after the effective date of the new guidance. Regions is evaluating the impact to its consolidated financial statements upon adoption. In March 2016, the FASB issued new accounting guidance that clarifies that entities should solely use the four-step decision sequence described in current derivatives accounting guidance. This sequence should be used when assessing whether contingent exercise provisions associated with a put or call option are clearly and closely related to their debt hosts. Based on differences in interpretation, some entities have also included an additional assessment, which considers whether the event that triggers the ability to exercise the put or call is indexed only to interest rates or credit risk of the entity. This additional assessment potentially results in bifurcation of more embedded options than would occur when just applying the decision sequence outlined in the guidance. This guidance should be applied to existing debt instruments on a modified retrospective basis and is effective for annual, and interim periods therein, beginning after December 15, 2016. Regions is evaluating the impact to its consolidated financial statements upon adoption. In March 2016, the FASB issued new accounting guidance that eliminates the requirement for an investor to retrospectively apply the equity method to investments when its ownership interest (or degree of influence in an investee) increases to a level that triggers the equity method of accounting. Currently, an entity must retrospectively adjust the investment, results of operations, and retained earnings as if the equity method had been in effect during all previous periods the investment was held. By eliminating this requirement, the FASB expects to reduce the cost and complexity when transitioning to the equity method. The guidance is effective for annual and interim periods beginning after December 15, 2016. Early adoption is permitted. Regions believes the adoption of this guidance will not have a material impact to its consolidated financial statements. In March 2016, the FASB issued new accounting guidance that intends to improve and simplify accounting for employee shared-based payments. The new guidance: (a) eliminates additional paid-in capital pools and designates that all excess tax benefits and deficiencies should be recorded in the income statement as income tax expense or benefit when the awards vest or are settled; entities should account for these income tax effects as discrete items in the reporting period in which they occur and exclude them from the estimated annual effective tax rate; (b) increases the permitted tax withholding limits from the employer’s statutory minimum rate to the employee’s maximum statutory rate before triggering liability classification; (c) changes the classification of excess tax benefits from a financing activity to an operating activity; (d) clarifies that cash paid to a tax authority when shares are withheld to satisfy an employer’s statutory income tax withholding obligation is a financing activity; (e) allows an entity to make an entity-wide accounting policy election to either account for forfeitures based on the number of awards that are expected to vest or account for forfeitures as they occur. The guidance is effective for interim and annual periods beginning after December 31, 2016. The method of accounting application (i.e. prospective, retrospective or modified retrospective application) differs by amendment and is defined in the guidance. Early adoption is permitted, but entities must adopt all of the guidance in the same period. Regions is not early adopting and believes the adoption of this guidance will not have a material impact to its consolidated financial statements. In April 2016, the FASB issued new accounting guidance for revenue recognition that is related to contracts with customers. This guidance is expected to clarify how an entity should evaluate revenue in circumstances regarding granting licenses of intellectual property. The guidance also includes information regarding identifying differences when dealing with promised goods and services. The guidance is effective for annual and interim periods beginning after December 15, 2017. Regions is evaluating the impact to its consolidated financial statements upon adoption. In May 2016, the FASB issued another new accounting guidance for revenue recognition that is related to contracts with customers. This guidance, as well as the guidance issued in April 2016, is intended to promote more consistent application of the standards as well as reduce the cost and complexity of applying the revenue guidance. The guidance contains amendments related to collectability, noncash consideration, and completed contracts at transition. The guidance is effective for annual and interim periods beginning after December 15, 2017. Regions is evaluating the impact to its consolidated financial statements upon adoption. In June 2016, the FASB issued new accounting guidance regarding the measurement of credit losses on financial instruments. The new guidance will apply to most financial assets measured at amortized cost and certain other instruments including loans, debt securities held to maturity, net investments in leases and off-balance-sheet credit exposures (e.g., loan commitments, standby letters of credit, etc.). The guidance will replace the current incurred loss accounting model with an expected loss approach, whereby entities must consider all available relevant information when estimating those expected credit losses, including details about past events, current conditions and reasonable and supportable forecasts. The guidance eliminates the current accounting model for purchased credit impaired loans and debt securities. Regarding securities available for sale, credit losses are to be recognized as allowances rather than reductions in the amortized cost of the securities, which will require remeasurement of the related allowance at each reporting period. The guidance includes enhanced disclosure requirements intended to help financial statement users better understand estimates and judgments used in estimating credit losses. The guidance is effective for annual and interim periods beginning after December 15, 2019. However, entities can apply these amendments as early as fiscal years beginning after December 15, 2018. Regions is evaluating the impact to its consolidated financial statements upon adoption.

Schedule Of Carrying Amounts And Estimated Fair Values Of Financial Instruments	The carrying amounts and estimated fair values, as well as the level within the fair value hierarchy, of the Company’s financial instruments as of June 30, 2016 are as follows: June 30, 2016 Carrying Amount Estimated Fair Value (1) Level 1 Level 2 Level 3 (In millions) Financial assets: Cash and cash equivalents $ 4,237 $ 4,237 $ 4,237 $ — $ — Trading account securities 117 117 117 — — Securities held to maturity 1,646 1,707 1 1,706 — Securities available for sale 23,494 23,494 498 22,988 8 Loans held for sale 551 551 — 445 106 Loans (excluding leases), net of unearned income and allowance for loan losses (2)(3) 79,608 75,322 — — 75,322 Other earning assets (4) 744 744 — 744 — Derivative assets 1,270 1,270 2 1,251 17 Financial liabilities: Derivative liabilities 945 945 — 945 — Deposits 97,245 97,335 — 97,335 — Short-term borrowings 2 2 — 2 — Long-term borrowings 8,968 9,258 — 5,828 3,430 Loan commitments and letters of credit 98 515 — — 515 Indemnification obligation 61 54 — — 54 _________ (1) 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 interest rates, market liquidity and credit spreads as appropriate. (2) 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 at June 30, 2016 was $4.3 billion or 5.4 percent. (3) Excluded from this table is the capital lease carrying amount of $943 million at June 30, 2016 .

[1]	Excluded from this table is the capital lease carrying amount of $943 million at June 30, 2016.
[2]	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 at June 30, 2016 was $4.3 billion or 5.4 percent.
[3]	Excluded from this table is the capital lease carrying amount of $916 million at December 31, 2015.
[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 at December 31, 2015 was $3.7 billion or 4.7 percent.
[5]	Excluded from this table is the operating lease carrying amount of $772 million at June 30, 2016.
[6]	Excluded from this table is the operating lease carrying amount of $834 million at December 31, 2015.
[7]	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 interest rates, market liquidity and credit spreads as appropriate.
