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 primarily in Alabama, Arkansas, Florida, Georgia, Illinois, Indiana, Iowa, Kentucky, Louisiana, Mississippi, Missouri, North Carolina, South Carolina, Tennessee, Texas and Virginia. The Company is subject to competition from other financial institutions, is subject to the regulations of certain government agencies and undergoes periodic examinations by certain of those 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 accounting principles generally accepted in the United States (“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’ Form 10-K for the year ended December 31, 2013. 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 & Company, Inc. (“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, 2013.
	Certain amounts in prior period financial statements have been reclassified to conform to the current period presentation. For example, the "card and ATM fees" line item on the consolidated statements of income represents the combined amounts of credit card/bank card income and debit card and ATM related revenue. Debit card and ATM related revenue was previously included in the "service charges on deposit accounts" line item. Credit card/bank card income was previously included in the "other" non-interest income line item. These reclassifications are immaterial and have no effect on net income, comprehensive income, total assets or total stockholders’ equity as previously reported.

	(1) The gross unrealized losses recognized in other comprehensive income (OCI) on held to maturity securities resulted from a transfer of available for sale securities to held to maturity in the second quarter of 2013.
	During the second quarter of 2013, Regions transferred securities with a fair value of $2.4 billion from available for sale to held to maturity. Management determined it has both the positive intent and ability to hold these securities to maturity. The securities were reclassified at fair value at the time of transfer and represented a non-cash transaction. Accumulated other comprehensive income included net pre-tax unrealized losses of $111 million on the securities at the date of transfer. These unrealized losses and the offsetting OCI components are being amortized into net interest income over the remaining life of the related securities as a yield adjustment, resulting in no impact on future net income.
	Equity securities in the tables above included the following amortized cost related to Federal Reserve Bank stock and Federal Home Loan Bank (“FHLB”) stock. Shares in the Federal Reserve Bank and FHLB are accounted for at amortized cost, which approximates fair value.

The amortized cost and estimated fair value of securities available for sale and securities held to maturity at September 30, 2014, by contractual maturity, are shown below. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

The following tables present gross unrealized losses and the related estimated fair value of securities available for sale and held to maturity at September 30, 2014 and December 31, 2013. For securities transferred to held to maturity from available for sale, the analysis in the tables below is comparing the securities' original amortized cost to its current estimated fair value. These securities are segregated between investments that have been in a continuous unrealized loss position for less than twelve months and for twelve months or more.

The number of individual securities in an unrealized loss position in the tables above decreased from 1,052 at December 31, 2013 to 834 at September 30, 2014. The decrease in the number of securities and the total amount of unrealized losses from year-end 2013 was primarily due to changes in interest rates. In instances where an unrealized loss did occur, there was no indication of an adverse change in credit on any of the underlying securities in the tables above. Management believes no individual unrealized loss 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 securities before the recovery of their amortized cost basis, which may be at maturity.
At June 30, 2014, the Company made the decision to sell approximately $328 million of certain other securities available for sale that remained on the Company's balance sheet. As the Company intended to sell these securities, each security reflecting an unrealized loss was considered to have an other-than-temporary impairment. The table below reflects total other-than-temporary impairment losses recorded during the second quarter of 2014. All of these securities were subsequently sold during the third quarter of 2014.
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.

	During the three months ended September 30, 2014 and 2013, Regions purchased approximately $296 million and $277 million, respectively, in indirect loans from a third party. During the nine months ended September 30, 2014 and 2013, the comparable loan purchase amounts were approximately $814 million and $733 million, respectively.
	At September 30, 2014, $13.2 billion in loans held by Regions were pledged to secure borrowings from the FHLB. At September 30, 2014, an additional $29.4 billion of loans held by Regions were pledged to the Federal Reserve Bank.
	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, 2013, 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 nine months ended September 30, 2014 and 2013. The total allowance for loan losses and the related loan portfolio ending balances as of September 30, 2014 and 2013 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 loans and leases greater than or equal to $2.5 million and all troubled debt restructurings ("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.

PORTFOLIO SEGMENT RISK FACTORS
The following describe the risk characteristics relevant to each of the portfolio segments.
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 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 valuation of real estate.
Consumer—The consumer loan portfolio segment includes residential first mortgage, home equity, indirect, 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 lending, which is lending initiated through third-party business partners, largely consists of loans made through automotive dealerships. Consumer credit card includes Regions branded consumer credit card accounts. Other consumer loans include direct consumer installment 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 September 30, 2014 and December 31, 2013. 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 which 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.

In addition to the impaired loans detailed in the tables above, there were approximately $38 million in non-performing loans classified as held for sale at September 30, 2014, compared to $82 million at December 31, 2013. The loans are carried at an amount approximating a price which is expected to be recoverable through the loan sale market. During the three months ended September 30, 2014 and 2013, approximately $36 million and $27 million, respectively, in non-performing loans were transferred to held for sale; these amounts are net of charge-offs of $11 million and $14 million, respectively, recorded upon transfer. During the nine months ended September 30, 2014 and 2013, approximately $69 million and $96 million, respectively, in non-performing loans were transferred to held for sale; these amounts are net of charge-offs of $26 million and $55 million, respectively, recorded upon transfer. At September 30, 2014 and December 31, 2013, non-accrual loans including loans held for sale totaled $875 million and $1.2 billion, respectively.
TROUBLED DEBT RESTRUCTURINGS
The majority of Regions’ commercial and investor real estate TDRs are the result of renewals of classified loans at an interest rate that is not considered to be a market rate. Consumer TDRs primarily involve an interest rate concession and not a forgiveness of principal. Accordingly, the financial impact of the modifications is best illustrated by the impact to the allowance calculation at the loan or pool level, as a result of the loans being considered impaired due to their status as TDRs. Regions most often does not record a charge-off at the modification date.
None of the modified consumer loans listed in the following TDR disclosures were collateral-dependent at the time of modification. At September 30, 2014, approximately $73 million in residential first mortgage TDRs were in excess of 180 days past due and were considered collateral-dependent. At September 30, 2014, approximately $8 million in home equity first lien TDRs were in excess of 180 days past due and approximately $6 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 in the consolidated financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2013.
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 $316 million and $607 million for the nine months ended September 30, 2014 and 2013, respectively.

Defaulted TDRs
The following table presents TDRs by portfolio segment and class which defaulted during the three and nine months ended September 30, 2014 and 2013, and which were modified in the previous twelve months (i.e., the twelve months prior to the default). For purposes of this disclosure, default is defined as 90 days past due and still accruing for the consumer portfolio segment, and placement on non-accrual status for the commercial and investor real estate portfolio segments. Consideration of defaults in the calculation of the allowance for loan losses is described in detail in the consolidated financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2013.

Commercial and investor real estate loans that were on non-accrual status at the time of the latest modification are not included in the default table above, as they are already considered to be in default at the time of the restructuring. At September 30, 2014, approximately $73 million of commercial and investor real estate loans modified in a TDR during the three months ended September 30, 2014 were on non-accrual status. Approximately 13.1 percent of this amount was 90 days past due.
At September 30, 2014, Regions had restructured binding unfunded commitments totaling $151 million where a concession was granted and the borrower was in financial difficulty.

	The fair value of residential mortgage servicing rights 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 mortgage servicing rights. 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 mortgage servicing rights under the fair value measurement method:

	On March 29, 2013, the Company completed a transaction to purchase the rights to service approximately $3 billion in residential mortgage loans. The residential mortgage servicing rights asset was increased by the purchase price of approximately $28 million in the first quarter of 2013.
	Data and assumptions used in the fair value calculation, as well as the valuation’s sensitivity to rate fluctuations, related to residential mortgage servicing rights (excluding related derivative instruments) are as follows:
		30-Sep
		2014			2013
		(Dollars in millions)
	Unpaid principal balance	$	26,943		$	28,234
	Weighted-average prepayment speed (CPR; percentage)	10.9		%	9.4		%
	Estimated impact on fair value of a 10% increase	$	(15	)	$	(12	)
	Estimated impact on fair value of a 20% increase	$	(28	)	$	(24	)
	Option-adjusted spread (basis points)	789			1,014
	Estimated impact on fair value of a 10% increase	$	(8	)	$	(10	)
	Estimated impact on fair value of a 20% increase	$	(17	)	$	(20	)
	Weighted-average coupon interest rate	4.5		%	4.5		%
	Weighted-average remaining maturity (months)	279			279
	Weighted-average servicing fee (basis points)	27.8			27.7
	The sensitivity calculations above are hypothetical and should not be considered to be predictive of future performance. Changes in fair value based on adverse changes in assumptions generally cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. Also, the effect of an adverse variation in a particular assumption on the fair value of the residential mortgage servicing rights 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 September 30						Nine Months Ended September 30
		2014			2013			2014			2013
		(In millions)
	Servicing related fees and other ancillary income	$	21		$	22		$	64		$	64
	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 a repurchase liability related to 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. The table below presents an analysis of Regions’ repurchase liability related to mortgage loans sold with representations and warranty provisions:
		Three Months Ended September 30						Nine Months Ended September 30

	Losses	(1		)	(8		)	(8		)	(23		)
	Ending balance	$	28		$	40		$	28		$	40
	For the periods presented, settled repurchase claims were related to one or more of the following alleged breaches: 1) eligibility or guideline violations; 2) missing or incorrect documents per investor guidelines; or 3) misrepresentation or fraud by the borrower. These claims stem primarily from loans originated in the 2006—2008 time period.
	COMMERCIAL MORTGAGE BANKING ACTIVITIES
	On July 18, 2014, Regions was approved as a Fannie Mae Delegated Underwriting and Servicing ("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 mortgage servicing rights and $15 million in intangible assets associated with the DUS license purchased.
	As of September 30, 2014, the DUS servicing portfolio remained at approximately $1.0 billion, and the related commercial MSRs and DUS license intangible asset were approximately $12 million and $15 million, respectively.
	Commercial MSRs are recorded in other assets on the Consolidated Balance Sheets at the lower of cost or market and are amortized in proportion to, and over the estimated period, that net servicing income is expected to be received based on projections of the amount and timing of estimated future net cash flows. The amount and timing of estimated future net cash flows are updated based on actual results and updated projections. Regions will periodically evaluate its commercial MSRs for impairment.
	The intangible asset associated with the DUS license purchased is recorded in other identifiable intangible assets on the Consolidated Balance Sheets, and is a non-amortizing intangible asset. This investment will be evaluated for impairment annually or more frequently if events or changes in circumstances indicate that it is more likely than not that the asset is impaired.

	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 in the Annual Report on Form 10-K for the year ended December 31, 2013. 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 third quarter of 2014, Regions assessed events and circumstances for all three reporting units as of September 30, 2014 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.
	Results of the 2013 annual test indicated that the estimated fair value of each reporting unit exceeded its carrying amount 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 values as of September 30, 2014. Therefore, Regions determined that a test of goodwill impairment was not required for each of Regions’ reporting units for the September 30, 2014 interim period.

	(1) Dividends, if declared, will be paid quarterly at an annual rate equal to (i) for each period beginning prior to September 15, 2024, 6.375%, and (ii) for each period beginning on or after September 15, 2024, three-month LIBOR plus 3.536%.
	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 each of the first, second, and third quarters of both 2014 and 2013. There were no cash dividends on Series B Preferred Stock during the second quarter of 2014 because the initial quarterly dividend was declared on July 17, 2014. Series B Preferred Stock dividends were $12 million for the third quarter of 2014. Because the Company was in a retained deficit position, preferred dividends were recorded as a reduction of preferred stock, including related surplus.
	COMMON STOCK
	On March 19, 2013, Regions' Board of Directors authorized a $350 million common stock repurchase plan, permitting repurchases from the beginning of the second quarter of 2013 through the end of the first quarter of 2014. During the first quarter of 2014, Regions repurchased approximately 1 million shares of common stock under this plan at a total cost of approximately $8 million. As of March 31, 2014, Regions had repurchased approximately 37 million shares of common stock at a total cost of approximately $347 million. The total cost paid to repurchase common shares under this plan includes the full amount paid as part of a contractual repurchase agreement. All common shares repurchased under this plan were immediately retired and therefore are not included in treasury stock. On April 1, 2014, the remaining approximately $3 million available under this plan expired.
	During the first quarter of 2014, Regions received no objection to its 2014 capital plan from the Federal Reserve that was submitted as part of the Comprehensive Capital Analysis and Review ("CCAR") process. On April 24, 2014, Regions' Board of Directors approved an increase of its quarterly common stock dividend to $0.05 per share effective with the quarterly dividend to be paid in July 2014. The Board also authorized a new $350 million common stock repurchase plan, permitting repurchases from the beginning of the second quarter of 2014 through the end of the first quarter of 2015. There were no shares repurchased under this plan as of September 30, 2014. However, the Company began purchasing shares in October 2014, and as of November 4, 2014, Regions had repurchased approximately 11.6 million shares of common stock at a total cost of approximately $114.7 million. These shares were immediately retired upon repurchase and therefore will not be included in treasury stock.
	The Board of Directors declared a $0.05 per share cash dividend on common stock for the second and third quarters of 2014, and a $0.03 per share cash dividend for the first quarter of 2014, totaling $0.13 per share cash dividend for the first nine months of 2014. The Board of Directors declared a $0.03 per share cash dividend on common stock for the second and third quarters of 2013 and a $0.01 per share cash dividend for the first quarter of 2013, totaling $0.07 per share cash dividend for the first nine months of 2013.

	SHARE-BASED PAYMENTS
	Regions administers long-term incentive compensation plans that permit the granting of incentive awards in the form of stock options, restricted stock awards, performance awards and stock appreciation rights. While Regions has the ability to issue stock appreciation rights, none have been issued to date. 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 shareholders. 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 May 13, 2010, the shareholders of the Company approved the Regions Financial Corporation 2010 Long-Term Incentive Plan (“2010 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 2010 LTIP authorizes 100 million common share equivalents available for grant, where grants of options count as one share equivalent and grants of full value awards (e.g., shares of restricted stock, restricted stock units and performance stock units) count as 2.25 share equivalents. Unless otherwise determined by the Compensation Committee of the Board of Directors, grants of restricted stock, restricted stock units, and performance stock units accrue dividends, or their notional equivalent, as they are declared by the Board of Directors, and are paid upon vesting of the award. Upon adoption of the 2010 LTIP, Regions closed all prior long-term incentive plans to new grants, and, accordingly, prospective grants must be made under the 2010 LTIP or a successor plan. All existing grants under prior long-term incentive plans were unaffected by adoption of the 2010 LTIP. The number of remaining share equivalents available for future issuance under the 2010 LTIP was approximately 42 million at September 30, 2014.

	During the first nine months of 2014 and 2013, Regions made restricted stock grants that vest upon service conditions and restricted stock unit and performance stock unit grants that vest based upon service conditions and performance conditions. 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.

	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 supplemental executive retirement program (the "SERP"), which is a non-qualified pension plan that provides certain senior executive officers defined benefits in relation to their compensation.

	The settlement charge relates to the settlement of liabilities under the SERP for certain executive officers during the second quarter of 2014.
	Regions' policy for funding the qualified pension plan is to contribute annually at least the amount required by Internal Revenue Service minimum funding standards. During the third quarter of 2014, Regions made a contribution of approximately $3 million to the plan.
	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 nine months ended September 30, 2014 or 2013.

	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, 2013 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 securities. These agreements involve the payment of fixed-rate amounts in exchange for floating-rate interest receipts. Regions also enters into forward sale commitments to hedge changes in the fair value of available-for-sale securities.
	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 $40 million and $70 million in accumulated other comprehensive income (loss) at September 30, 2014 and 2013, respectively, related to terminated cash flow hedges of loan and debt instruments which will be amortized into earnings in conjunction with the recognition of interest payments through 2017. Regions recognized pre-tax income of $14 million and $12 million during the three months ended September 30, 2014 and 2013, respectively, and pre-tax income of $37 million and $35 million during the nine months ended September 30, 2014 and 2013, respectively, related to the amortization of cash flow hedges of loan and debt instruments.
	Regions expects to reclassify out of accumulated other comprehensive income (loss) and into earnings approximately $120 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 $44 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 seven years as of September 30, 2014.

DERIVATIVES NOT DESIGNATED AS HEDGING INSTRUMENTS
The Company maintains a derivatives trading portfolio of interest rate swaps, option contracts, and futures and forward commitments used to meet the needs of its customers. The portfolio is primarily used to help clients manage market risk. The Company is subject to the credit risk that a counterparty will fail to perform. The Company is also subject to market risk, which is evaluated by the Company and monitored by the asset/liability management process. Separate derivative contracts are entered into to reduce overall market exposure to pre-defined limits. The contracts in this portfolio do not qualify for hedge accounting and are marked-to-market through earnings and included in other assets and other liabilities.
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 September 30, 2014 and December 31, 2013, Regions had $312 million and $267 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, which are recorded at fair value with changes in fair value recorded in mortgage income. At September 30, 2014 and December 31, 2013, Regions had $697 million and $636 million, respectively, in total notional amount related to these forward sale commitments.
Regions has elected to account for residential mortgage servicing rights 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 consolidated statement of income effect of changes in the fair value of its residential mortgage servicing rights. As of both September 30, 2014 and December 31, 2013, the total notional amount related to these contracts was $3.4 billion.
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 nine months ended September 30, 2014 and 2013:

Credit risk, defined as all positive exposures not collateralized with cash or other assets or reserved for, at September 30, 2014 and December 31, 2013, totaled approximately $343 million and $453 million, respectively. This amount represents 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 when the customer fails to make payment on any amounts due to Regions upon early termination of the swap transaction and have maturities between 2015 and 2020. Credit derivatives whereby Regions has sold credit protection have maturities between 2015 and 2020. For contracts where Regions sold credit protection, Regions would be required to make payment to the counterparty when 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 September 30, 2014 was approximately $60 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 September 30, 2014 and 2013 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.
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 value of all derivative instruments with any credit-risk-related contingent features that were in a liability position on September 30, 2014 and December 31, 2013, was $294 million and $364 million, respectively, for which Regions had posted collateral of $311 million and $409 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 September 30, 2014 and December 31, 2013.

________
-1	At September 30, 2014, gross amounts of derivative assets and liabilities offset in the consolidated balance sheets presented above include cash collateral received of $24 million and cash collateral posted of $396 million. At December 31, 2013, gross amounts of derivative assets and liabilities offset in the consolidated balance sheets presented above include cash collateral received of $42 million and cash collateral posted of $501 million.
Gross amounts not subject to offsetting consist primarily of derivatives cleared through central clearing houses and interest rate lock commitments to originate mortgage loans. Regions does not have legal assurance that the clearing house contracts are master netting agreements, and therefore has not offset them on its balance sheet.

	FAIR VALUE MEASUREMENTS
	Fair value guidance establishes a framework for using fair value to measure assets and liabilities and defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) as opposed to the price that would be paid to acquire the asset or received to assume the liability (an entry price). A fair value measure should reflect the assumptions that market participants would use in pricing the asset or liability, including the assumptions about the risk inherent in a particular valuation technique, the effect of a restriction on the sale or use of an asset and the risk of nonperformance. Required disclosures include stratification of balance sheet amounts measured at fair value based on inputs the Company uses to derive fair value measurements. These strata include:
	•	Level 1 valuations, where the valuation is based on quoted market prices for identical assets or liabilities traded in active markets (which include exchanges and over-the-counter markets with sufficient volume),
	•	Level 2 valuations, where the valuation is based on quoted market prices for similar instruments traded in active markets, quoted prices for identical or similar instruments in markets that are not active and model-based valuation techniques for which all significant assumptions are observable in the market, and
	•	Level 3 valuations, where the valuation is generated from model-based techniques that use significant assumptions not observable in the market, but observable based on Company-specific data. These unobservable assumptions reflect the Company’s own estimates for assumptions that market participants would use in pricing the asset or liability. Valuation techniques typically include option pricing models, discounted cash flow models and similar techniques, but may also include the use of market prices of assets or liabilities that are not directly comparable to the subject asset or liability.
	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, 2013 for a description of valuation methodologies for assets and liabilities measured at fair value on a recurring and non-recurring basis. Regions rarely transfers assets and liabilities measured at fair value between Level 1 and Level 2 measurements. There were no such transfers during the nine month periods ended September 30, 2014 and 2013. 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 best method of pricing for an individual security. 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 September 30, 2014 and December 31, 2013:

	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 a rollforward for all assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the three and nine months ended September 30, 2014 and 2013. 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. The net changes in realized gains (losses) included in earnings related to Level 3 assets and liabilities held at September 30, 2014 and 2013 are not material.

RECURRING FAIR VALUE MEASUREMENTS USING SIGNIFICANT UNOBSERVABLE INPUTS
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, constant prepayment rate, probability of default, and loss severity in the event of default. Significant increases in any of these inputs in isolation would result in significantly lower fair value measurement. Generally, a change in the assumption used for the probability of default is accompanied by a directionally similar change in the assumption used for loss severity and a directionally opposite change in the assumption used for prepayment rates.
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 other debt securities.
Residential mortgage servicing rights
The significant unobservable inputs used in the fair value measurement of residential mortgage servicing rights ("MSR") are option adjusted spreads (“OAS”) and prepayment speed. This method 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. See Note 5 for these amounts and additional disclosures related to assumptions used in the fair value calculation for MSRs.
Derivative assets
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.
NON-RECURRING FAIR VALUE MEASUREMENTS USING SIGNIFICANT UNOBSERVABLE INPUTS
Loans held for sale
Commercial and investor real estate 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.
Residential first mortgage loans transferred to held for sale were valued based on estimated third-party valuations utilizing recent sales data from similar transactions. Broker opinion statements were also obtained as additional evidence to support the third-party valuations. The discounts taken were intended to represent the perspective of a market participant, considering among other things, required investor returns which include liquidity discounts reflected in similar bulk transactions.
Foreclosed property and other real estate
Foreclosed property and other real estate are 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.
FAIR VALUE OPTION
Regions has elected the fair value option for all FNMA and FHLMC eligible residential mortgage loans held for sale. 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 mortgage loans held for sale are based on traded market prices of similar assets where available and/or discounted cash flows at market interest rates, adjusted for securitization activities that include servicing values and market conditions, and are recorded in loans held for sale in the consolidated balance sheets.
The following table summarizes the difference between the aggregate fair value and the aggregate unpaid principal balance for mortgage loans held for sale measured at fair value:

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 nine months ended September 30, 2014 and 2013, respectively. 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.

-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 September 30, 2014 was $5.0 billion or 6.8 percent.

Commitments and Contingencies	'
	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:
		September 30, 2014		31-Dec-13
		(In millions)
	Unused commitments to extend credit	$	42,657	$	41,885
	Standby letters of credit	1,608		1,629
	Commercial letters of credit	47		36
	Liabilities associated with standby letters of credit	37		37
	Assets associated with standby letters of credit	36		38
	Reserve for unfunded credit commitments	65		78
	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 $208 million and an estimated fair value of approximately $193 million as of September 30, 2014 (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 is required to make a disclosure of the aggregate estimation. Regions currently estimates that it is reasonably possible that it may experience losses in excess of what Regions has accrued in an aggregate amount up to approximately $170 million as of September 30, 2014, with it also being reasonably possible that Regions could incur no losses in excess of amounts accrued. As available information changes, the matters for which Regions is able to estimate, as well as the estimates themselves will be adjusted accordingly. The reasonably possible estimate includes legal contingencies that are subject to the indemnification agreement with Raymond James.
	Assessments of litigation and claims exposure are difficult because they involve inherently unpredictable factors including, but not limited to, the following: whether the proceeding is in the early stages; whether damages are unspecified, unsupported, or uncertain; whether there is a potential for punitive or other pecuniary damages; whether the matter involves legal uncertainties, including novel issues of law; whether the matter involves multiple parties and/or jurisdictions; whether discovery has begun or is not complete; whether meaningful settlement discussions have commenced; and whether the lawsuit involves class allegations. Assessments of class action litigation, which is generally more complex than other types of litigation, are particularly difficult, especially in the early stages of the proceeding when it is not known if 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 provided 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 cases have been consolidated into class-actions and stockholder derivative actions for the open-end and closed-end Funds. The Funds were formerly managed by Regions Investment Management, Inc. (“Regions Investment Management”). Regions Investment Management no longer manages these Funds, which were transferred to Hyperion Brookfield Asset Management (“Hyperion”) in 2008. Certain of the Funds have since been terminated by Hyperion. The complaints contain various allegations, including claims that the Funds and the defendants misrepresented or failed to disclose material facts relating to the activities of the Funds. Plaintiffs have requested equitable relief and unspecified monetary damages. Settlement discussions are ongoing in certain cases, and the U.S. District Court for the Western District of Tennessee has granted final approval of a settlement in the closed-end Funds class-action and shareholder derivative case as well as preliminary approval of a settlement in a consolidated class action under the Employment Retirement Income Security Act. 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 October 2010, a purported class-action lawsuit was filed by Regions’ stockholders in the U.S. District Court for the Northern District of Alabama (the “District Court”) against Regions and certain former officers of Regions (the "2010 Claim"). The 2010 Claim alleges violations of the federal securities laws, including allegations that materially false and misleading statements were included in filings made with the Securities and Exchange Commission ("SEC"). The plaintiffs have requested equitable relief and unspecified monetary damages. In June 2011, the trial court denied Regions’ motion to dismiss the 2010 Claim. In June 2012, the trial court granted class certification. The Eleventh Circuit Court of Appeals on September 5, 2014, vacated certification in part and remanded the 2010 Claim to District Court for further review of the class certification issue.
	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 claims under a civil Racketeer Influenced and Corrupt Organizations (“RICO”) statute 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.
	The SEC and states of Missouri and Texas are investigating alleged securities law violations by Morgan Keegan in the underwriting and sale of certain municipal bonds. An enforcement action brought by the Missouri Secretary of State in April 2013, seeking monetary penalties and other relief, was dismissed and refiled in November 2013. A civil action was brought by institutional investors of the bonds in March 2012, seeking a return of their investment and unspecified compensatory and punitive damages. Trial of this case is currently set for March 2015 in the Circuit Court for Cole County, Missouri. A class action was brought on behalf of retail purchasers of the bonds in September 2012, seeking unspecified compensatory and punitive damages. In September 2014, the District Court for the Western District of Missouri granted class certification. The trial date which was originally set for September 2014 has been postponed and a new date has not been scheduled at this time. Other individual investors and investor groups have also filed arbitration claims or separate civil claims, which are pending in various stages. These matters are subject to the indemnification agreement with Raymond James.
	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.
	In 2013, Regions received investigative requests from government agencies regarding its residential mortgage loan origination, underwriting and quality control practices for Federal Housing Administration insured loans made by Regions. More recently, 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. These inquiries are part of industry-wide investigations, and Regions is cooperating with the inquiries. Many institutions have settled these matters on terms that included large monetary penalties, including, in some cases, civil money penalties under applicable banking laws. The Company cannot predict the ultimate outcome of the investigations concerning its practices, however it is possible that these investigations could result in the payment of a monetary penalty which may adversely affect results of operations.
	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 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 September 30, 2014, the carrying value of the indemnification obligation was approximately $208 million.
	VISA INDEMNIFICATION
	As a member of the Visa USA network, Regions, along with other members, indemnified Visa USA against litigation. On October 3, 2007, Visa USA was restructured and acquired several Visa affiliates. In conjunction with this restructuring, Regions' indemnification of Visa USA was modified to cover specific litigation (“covered litigation”).
	A portion of Visa's proceeds from its initial public offering ("IPO") was escrowed to fund the covered litigation. During the first quarter of 2013, Visa made a settlement payment related to the covered litigation which reduced Regions' share of the escrow account to approximately zero at March 31, 2013. Regions made a corresponding adjustment to reduce its liability to approximately zero at March 31, 2013. The balances related to the escrow and the corresponding liability are approximately zero as of September 30, 2014. To the extent that the amount available under the escrow arrangement, or subsequent fundings of the escrow account via reductions in the class B share conversion ratio, is insufficient to fully resolve the covered litigation, Visa will enforce the indemnification obligations of Visa USA's members for any excess amount. At this time, Regions has concluded that it is not probable that covered litigation exposure will exceed the class B share value.

	RECENT ACCOUNTING PRONOUNCEMENTS
	In July 2013, the Financial Accounting Standards Board ("FASB") issued final guidance on the presentation of certain unrecognized tax benefits in the financial statements. This guidance requires unrecognized tax benefits to be presented as a decrease in a deferred tax asset for a net operating loss carryforward, similar tax loss or tax credit carryforward if certain criteria are met. In situations in which a net operating loss carryforward, a similar tax loss or tax credit carryforward is not available at the reporting date under the tax law of the jurisdiction or the tax law of the jurisdiction does not require, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit will be presented in the financial statements as a liability and will not be combined with deferred tax assets. This guidance became effective for fiscal years and interim periods within those years beginning after December 15, 2013 and was adopted by Regions on a prospective basis with the first quarter of 2014 financial reporting. The guidance did not have a material impact upon adoption.
	In January 2014, the FASB issued new accounting guidance related to the accounting for investments in qualified affordable housing projects. The guidance allows the holder of low income housing tax credit ("LIHTC") investments to apply a proportional amortization method that would recognize the cost of the investment as a part of income tax expense, provided that the investment meets certain criteria. The guidance is silent regarding statement of financial position classification. Regions believes it would not be appropriate to classify the investment as a deferred tax asset. The decision to apply the proportional amortization method is an accounting policy election. Entities may also elect to continue to account for these investments using the equity method. The guidance will be applied retrospectively and is effective for fiscal years, and interim periods within those years, beginning after December 15, 2014. Early adoption is permitted. Regions is in the process of reviewing the potential impact the adoption of this guidance will have to its consolidated financial statements.
	In January 2014, the FASB issued new accounting guidance regarding the reclassification of residential real estate collateralized consumer mortgage loans upon foreclosures. The guidance requires reclassification of a consumer mortgage loan to other real estate owned upon obtaining legal title to the residential property, which could occur either through foreclosure or through a deed in lieu of foreclosure or similar legal agreement. The existence of a borrower redemption right will not prevent the lender from reclassifying a loan to other real estate once the lender obtains legal title to the property. In addition, entities are required to disclose the amount of foreclosed residential real estate properties and the recorded investment in residential real estate mortgage loans in the process of foreclosure on both an interim and annual basis. The guidance may be applied prospectively or on a modified retrospective basis in fiscal years, and interim periods within those fiscal years, beginning after December 15, 2014. Early adoption is permitted. Regions believes that adoption of this guidance will not have a material impact to its consolidated financial statements.
	In May 2014, the FASB and the International Accounting Standards Board (“IASB”) jointly issued a comprehensive new revenue recognition standard that will supersede nearly all existing revenue recognition guidance under U.S. GAAP and International Financial Reporting Standards ("IFRS"). The standard’s core principle is that an entity will recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. The guidance may be applied retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initial application recognized at the date of initial application for fiscal years and interim periods within those years beginning after December 15, 2016. Early application is not permitted. Regions is in the process of reviewing the potential impact the adoption of this guidance will have to its consolidated financial statements.
	In June 2014, the FASB issued new accounting guidance that requires two accounting changes related to the transfer and servicing of repurchase agreements and similar transactions. First, the amendments in the update change the accounting for repurchase-to-maturity transactions to secured borrowing accounting. Second, for repurchase financing arrangements, the amendments require separate accounting for a transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty, which will result in secured borrowing accounting for the repurchase agreement. The amendments in the update also require certain disclosures for transfers of financial assets and repurchase agreements. The accounting changes are effective for fiscal years and interim periods within those years beginning after December 15, 2014. The changes should be applied as a cumulative-effect adjustment to retained earnings at the beginning of the period of adoption. The disclosure of certain transactions accounted for as a sale is required to be presented for fiscal years and interim periods within those years beginning after December 15, 2014 and the disclosure for repurchase agreements, securities lending transactions, and repurchase-to-maturity transactions accounted for as secured borrowing is required to be presented for fiscal years beginning after December 15, 2014, and for interim periods beginning after March 15, 2015. Early application is not permitted. Regions is in the process of reviewing the potential impact the adoption of this guidance will have to its consolidated financial statements.
	In June 2014, the FASB issued new accounting guidance that requires a performance target that affects vesting and that could be achieved after the requisite service period to be treated as a performance condition. An entity should apply existing guidance that relates to awards with performance conditions that affect vesting to account for such awards. The guidance may be applied prospectively or retrospectively and is effective for fiscal years and interim periods within those years beginning after December 15, 2015. Early adoption is permitted. This guidance will not have a material impact upon adoption as Regions has no share-based grants with performance targets that could be achieved after the requisite service period.
	In August 2014, the FASB issued new accounting guidance regarding the classification and measurement of foreclosed mortgage loans that are guaranteed by the government (including loans guaranteed by the FHA and the VA). The guidance addresses diversity in practice by requiring creditors to derecognize the mortgage loan upon foreclosure and to recognize a separate other receivable if the following conditions are met: (a) the government guarantee of the loan is not separable from the loan before foreclosure; (b) upon foreclosure, the creditor has the intent to convey the real estate to the guarantor and to make a claim on the guarantee, and also has the ability to make a recovery under the claim; and (c) claim amounts based on the fair value of the property are fixed upon foreclosure. Upon foreclosure, the separate other receivable should be measured based on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. The guidance may be applied prospectively or on a modified retrospective basis in fiscal years, and interim periods within those fiscal years, beginning after December 15, 2014. The transition method applied should be the same as the transition method applied upon implementation of the new accounting guidance issued in January 2014, described above, regarding the reclassification of residential real estate collateralized consumer mortgage loans upon foreclosures. Early adoption is permitted. Regions believes that adoption of this guidance will not have a material impact to its consolidated financial statements.
	In August 2014, the FASB issued new accounting guidance to offer a measurement alternative for reporting entities that consolidate a collateralized financing entity ("CFE") in which the financial assets and financial liabilities are measured at fair value, with changes in fair values reflected in earnings. Under the measurement alternative, the reporting entity could elect to measure both the CFE’s financial assets and financial liabilities using the fair value of either the CFE’s financial assets or financial liabilities, whichever is more observable. Regions is in the process of reviewing the potential impact the adoption of this guidance will have to its consolidated financial statements.
	In August 2014, the FASB issued new accounting guidance that requires management to evaluate whether there are conditions and events that raise substantial doubt about an entity’s ability to continue as a going concern. The guidance is intended to incorporate into GAAP a requirement that management perform a going concern evaluation similar to the auditor’s evaluation required by standards issued by the Public Company Accounting Oversight Board ("PCAOB") and American Institute of Certified Public Accountants ("AICPA"). The guidance is effective for all entities for annual periods ending after December 15, 2016 and for annual and interim periods thereafter. Early application is permitted. Regions believes the adoption of this guidance will not have a material impact upon adoption.
	Further information related to recent accounting pronouncements and accounting changes adopted by Regions prior to the first quarter of 2014 is included in the Annual Report on Form 10-K for the year ended December 31, 2013.

	-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 September 30, 2014 was $5.0 billion or 6.8 percent.
	-3	Excluded from this table is the lease carrying amount of $1.7 billion at September 30, 2014.

	-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 December 31, 2013 was $5.4 billion or 7.6 percent.
	-3	Excluded from this table is the lease carrying amount of $1.7 billion at December 31, 2013.

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 September 30, 2014 was $5.0 billion or 6.8 percent.

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, 2013 was $5.4 billion or 7.6 percent.
[4]	Excluded from this table is the lease carrying amount of $1.7 billion at December 31, 2013.
[5]	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.
