Regions Financial Corporation is filinga FHC headquartered in Birmingham, Alabama operating in the South, Midwest and Texas. The terms "Regions," "the Company," "we," "us" and "our" mean Regions Financial Corporation, a Delaware corporation and its subsidiaries, when appropriate. Regions provides traditional commercial, retail and mortgage banking services, as well as other financial services in the fields of asset management, wealth management, securities brokerage, trust services, merger and acquisition advisory services, and other specialty financing. At December 31, 2019, Regions had total consolidated assets of approximately $126.2 billion, total consolidated deposits of approximately $97.5 billion and total consolidated stockholders’ equity of approximately $16.3 billion.

Firms subject to Category IV standards will generally be subject to the same capital and liquidity requirements as firms with less than $100 billion in total consolidated assets, but are, among other things, subject to certain enhanced prudential standards and also required to monitor and report certain risk-based indicators. Accordingly, under the Tailoring Rules, Category IV firms are, among other things, (1) not subject to LCR requirements (or, in certain cases, subject to reduced requirements), (2) no longer subject to company-run capital stress testing requirements, (3) subject to supervisory capital stress testing on a biennial instead of annual basis, (4) subject to requirements to develop and maintain a capital plan on an annual basis and (5) subject to certain liquidity risk management and risk committee requirements. A chart summarizing key elements of the capital, liquidity and enhanced prudential standards requirements applicable to Regions under the Tailoring Rules is included immediately below, and elements of the Tailoring Rules are discussed in further detail throughout this Amendment No.section.

In addition, Regions and Regions Bank are subject to the final rule adopted by the Federal Reserve, OCC and FDIC in July 2019 relating to simplifications of the capital rules applicable to non-advanced approaches banking organizations. These rules will be effective for the Company on April 1, 2020, and provide for simplified capital requirements relating to the threshold deductions for mortgage servicing assets, deferred tax assets arising from temporary differences that a banking organization could not realize through net operating loss carry backs, and investments in the capital of unconsolidated financial institutions, as well as the inclusion of minority interests in regulatory capital.

For more information, see the “Regulatory Requirements” section of Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this Annual Report on Form 10-K/A10-K.

The FDIA requires the federal banking agencies to take prompt corrective action in respect of depository institutions that do not meet specified capital requirements. The FDIA establishes five capital categories (“Form 10-K/A”well-capitalized,” “adequately capitalized,” “undercapitalized,” “significantly undercapitalized” and “critically undercapitalized”), and the federal banking agencies must take certain mandatory supervisory actions, and are authorized to take other discretionary actions, with respect to institutions that are undercapitalized, significantly undercapitalized or critically undercapitalized. The severity of these mandatory and discretionary supervisory actions depends upon the capital category in which the institution is placed. Generally, subject to a narrow exception, the FDIA requires the banking regulator to appoint a receiver or conservator for an institution that is critically undercapitalized. As of December 31, 2019, both Regions and Regions Bank were well-capitalized.

An institution that is categorized as undercapitalized, significantly undercapitalized or critically undercapitalized is required to submit an acceptable capital restoration plan to its appropriate federal banking regulator. Under the FDIA, in order for the capital restoration plan to be accepted by the appropriate federal banking agency, a BHC must guarantee that a subsidiary depository institution will comply with its capital restoration plan, subject to certain limitations. The BHC must also provide appropriate assurances of performance.

Additionally, if Regions were to be downgraded to below investment grade, certain counterparty contracts may be required to be renegotiated or require posting of additional collateral. Refer to Note 21 “Derivative Financial Instruments and Hedging Activities - Contingent Features” to the consolidated financial statements of this Annual Report on Form 10-K for the year endedfair value of contracts subject to contingent credit features and the collateral postings associated with such contracts. Although the exact amount of additional collateral is unknown, it is reasonable to conclude that Regions may be required to post additional collateral related to existing contracts with contingent credit features.

As of December 31, 20162019, we had $4.8 billion of goodwill and $105 million of other intangible assets. A significant decline in our expected future cash flows, a significant adverse change in the business climate, slower economic growth or a significant and sustained decline in the price of our common stock, any or all of which could be materially impacted by many of the risk factors discussed herein, may necessitate our taking charges in the future related to the impairment of our goodwill. Future regulatory actions could also have a material impact on assessments of goodwill for impairment. If we were to conclude that a future write-down of our goodwill is necessary, we would record the appropriate charge, which could have a material adverse effect on our results of operations.

Financial services companies are interrelated as fileda result of trading, clearing, counterparty or other relationships. We have exposure to many different industries and counterparties, and we routinely execute transactions with counterparties in the financial services industry, including brokers and dealers, commercial banks, investment banks, mutual and hedge funds, and other institutional clients. As a result, defaults by, or even mere speculation about, one or more financial services companies, or the financial services industry generally, may lead to market-wide liquidity problems and could lead to losses or defaults by us or by other institutions. Many of these transactions expose us to credit risk in the event of default of our counterparty or client. In addition, our credit risk may be exacerbated if the collateral held by us cannot be realized or is liquidated at prices not sufficient to recover the full amount of the loan or lease or derivative exposure due us. Any such losses may materially and adversely affect our business, financial condition or results of operations.

In April 2012, Regions closed the sale of Morgan Keegan and related affiliates to Raymond James. In connection with the Securitiessale, Regions agreed to indemnify Raymond James for all litigation and Exchange Commissioncertain other matters related to pre-closing activities of Morgan Keegan. Indemnifiable losses under the indemnification provision include legal and other expenses, such as costs for defense, judgments, settlements and awards associated with the resolution of litigation related to pre-closing activities. As of December 31, 2019, the carrying value of the indemnification obligation is immaterial and reflects an estimate of liability; however,

Any changes in any federal and state law, as well as regulations and governmental policies, income tax laws and accounting principles, could affect us in substantial and unpredictable ways, including ways that may adversely affect our business, financial condition or results of operations. Failure to appropriately comply with any such laws, regulations or principles could result in sanctions by regulatory agencies, civil money penalties or damage to our reputation, all of which could adversely affect our business, financial condition or results of operations. Our regulatory position is discussed in greater detail in Note 13 “Regulatory Capital Requirements and Restrictions” in the Notes to the Consolidated Financial Statements in Item 7.8. of this Annual Report on Form 10-K.

Regions and Regions Bank are each required to comply with applicable capital adequacy standards established by the Federal Reserve, which are based on the Basel III framework. The Basel Committee has published standards that it describes as the finalization of the Basel III post-crisis regulatory reforms. These standards will generally be effective on January 1, 2022, with an aggregate output floor phasing in through January 1, 2027. Among other things, these standards revise the standardized approach for credit risk and provide a new standardized approach for operational risk capital. The impact of these standards on us will depend on the manner in which the revisions are implemented in the U.S. with respect to firms such as Regions and Regions Bank.

We are a legal entity separate and distinct from our banking and other subsidiaries. Our principal source of cash flow, including cash flow to pay dividends to our stockholders and principal and interest on our outstanding debt, is dividends from Regions Bank. There are statutory and regulatory limitations on the payment of dividends by Regions Bank to us, as well as by us to our stockholders. Regulations of both the Federal Reserve and the State of Alabama affect the ability of Regions Bank to pay dividends and other distributions to us and to make loans to us. If Regions Bank is unable to make dividend payments to us and sufficient cash or liquidity is not otherwise available, we may not be able to make dividend payments to our common and preferred stockholders or principal and interest payments on our outstanding debt. See the “Stockholders’ Equity” section of Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this Annual Report on Form 10-K. Disclosures appearingIn addition, our right to participate in a distribution of assets upon a subsidiary’s liquidation or reorganization is subject to the prior claims of creditors of that subsidiary, except to the extent that any of our claims as a creditor of such subsidiary may be recognized. As a result, shares of our capital stock are effectively subordinated to all existing and future liabilities and obligations of our subsidiaries. At December 31, 2019, our subsidiaries’ total deposits and borrowings were approximately $107.3 billion.

We are also subject to statutory and regulatory limitations on our ability to pay dividends on our capital stock. For example, it is the policy of the Original Filing,Federal Reserve that BHCs should generally pay dividends on common stock only out of earnings, and only if prospective earnings retention is consistent with the organization’s expected future needs, asset quality and financial condition. Moreover, the Federal Reserve may closely scrutinize any dividend payout ratios exceeding 30% of after-tax net income. Additionally, we are currently required to submit annual capital plans to the Federal Reserve for review before we can take certain capital actions, including declaring and paying dividends and repurchasing or redeeming capital securities. If our capital plan or any amendment to our capital plan is objected to for any reason, our ability to declare and pay dividends on our capital stock may be limited. Further, if we are unable to satisfy the capital requirements applicable to us for any reason, we may be limited in our ability to declare and pay dividends on our capital stock.

Refer to the "Allowance for Credit Losses" section of Management's Discussion and classified commercial loans, attributable primarily to downward risk rating migration in the energy portfolio.  This increase was offset by the impact of $2.0 billion in business services loan balance runoff, including $436 million in direct energy, and improvement in the risk profile of certain other loan classes.

Under the Federal Reserve published the final Basel III Rules, establishing an updated comprehensive capital framework for U.S. banking organizations.Regions is designated as a standardized approach bank. The Basel III Rules substantially revised the regulatory capital requirements applicable to BHCs and depository institutions, including Regions and Regions Bank. The Basel III Rules were effective for Regions and Regions Bank beginning January 1, 2015 (subject to a phase-in period), and maintained the minimum guidelines for Regions to be considered well-capitalized for Tier 1 capital and Total capital at 6.0% and 10.0%, respectively. At December 31, 2016,2019, Regions’ Basel III Tier 1 capital and Total capital ratios were estimated to be 11.98%10.91% and 14.15%12.68%, respectively.

The Basel III Rules also officially defined CET1. When fully phased in on January 1, 2019, the minimum ratio of CET1 to risk-weighted assets will be at least 4.5%, plus a 2.5% “capital conservation buffer” (which is added to the 4.5% CET1 ratio as that buffer is phased in, effectively resulting in a minimum ratio of CET1 to risk-weighted assets of at least 7.0% upon full implementation). Regions' Basel III CET1 ratio at December 31, 2016 on a transitional basis2019 was estimated to be 11.21%. Regions’ understanding of the framework is evolving and will likely change as analysis and discussions with regulators continue. Based on its current understanding, Regions estimates its fully phased-in CET1 ratio (non-GAAP) at December 31, 2016 to be 11.05%9.68%.

The following discussion and financial information is presented to aid in understanding Regions’ financial position and results of operations. The emphasis of this discussion will be on continuing operations for the years 2016, 20152019 and 2014;2018; in addition, financial information for prior years will also be presented when appropriate.

Regions’ profitability, like that of many other financial institutions, is dependent on its ability to generate revenue from net interest income and other financing income as well as non-interest income sources. Net interest income and other financing income is primarily the difference between the interest income Regions receives on interest-earning assets, such as loans and securities, and the interest expense Regions pays on interest-bearing liabilities, principally deposits and borrowings. Regions’ net interest income and other financing income is impacted by the size and mix of its balance sheet components and the interest rate spread between interest earned on its assets and interest paid on its liabilities. Net interest income and other financing income also includes rental income and depreciation expense associated with operating leases for which Regions is the lessor. Non-interest income includes fees from service charges on deposit accounts, card and ATM fees, mortgage servicing and secondary marketing, investment management and trust activities, insurance activities, capital markets and other customer services which Regions provides. Results of operations are also affected by the provision for loan losses and non-interest expenses such as salaries and employee benefits, occupancy, professional, legal and regulatory expenses, FDIC insurance assessments, and other operating expenses, as well as income taxes.

Economic conditions, competition, new legislation and related rules impacting regulation of the financial services industry and the monetary and fiscal policies of the Federal government significantly affect most, if not all, financial institutions, including Regions. Lending and deposit activities and fee income generation are influenced by levels of business spending and investment, consumer income, consumer spending and savings, capital market activities, and competition among financial institutions, as well as customer preferences, interest rate conditions and prevailing market rates on competing products in Regions’ market areas.

Regions’ business strategy has been and continues to beis focused on providing a competitive mix of products and services, delivering quality customer service, and maintainingcontinuing to develop and optimize distribution channels that include a branch distribution network with offices in convenient locations.locations, as well as electronic and mobile banking.

Regions provides traditional commercial, retail and mortgage banking services, as well as other financial services in the fields of asset management, wealth management, securities brokerage, insurance and other specialty financing. Regions carries out its strategies and derives its profitability from 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.
