Associated Banc-Corp (individually referred to herein as the “Parent Company” and together with all of its subsidiaries and affiliates, collectively referred to herein as the “Corporation,” “Associated,” “we,” “us,” or “our”) is a bank holding company registered pursuant to the Bank Holding Company Act of 1956, as amended (the “BHC Act”).BHC Act. Our bank subsidiary, Associated Bank National Association (“Associated Bank” or the “Bank”) traces its history back to the founding of the Bank of Neenah in 1861. We were incorporated in Wisconsin in 1964 and were inactive until 1969 when permission was received from the Board of Governors of the Federal Reserve System (the “Federal Reserve” or “FRB” )Board to acquire three banks. At December 31, 2016,2019, we owned one nationally chartered commercial bank headquartered in Green Bay, Wisconsin, which serves local communities across the upper Midwest, one nationally chartered trust company headquartered in Wisconsin, and 1012 limited purpose banking and nonbanking subsidiaries either located in or conducting business primarily in our three-state footprint (Wisconsin,

Through Associated Bank and various nonbanking subsidiaries, we provide a broad array of banking and nonbanking products and services to individuals and businesses through 217248 banking branches at December 31, 2019 serving more than 100120 communities, primarily within our three state branch footprint. Our business is primarily relationship-driven and is organized into three reportable segments: Corporate and Commercial Specialty; Community, Consumer, and Business; and Risk Management and Shared Services.

See Note 21 Segment Reporting of the notes to consolidated financial statements in Part II, Item 8, “FinancialFinancial Statements and Supplementary Data,” for additional information concerning our reportable segments.

We are not dependent upon a single or a few customers, the loss of which would have a material adverse effect on us.

At December 31, 2016,2019, we had 4,4414,669 full-time equivalent employees. None of our employees are represented by unions.

The financial services industry is highly competitive. We compete for loans, deposits, and financial services in all of our principal markets. We compete directly with other bank and nonbank institutions located within our markets, internet-based banks, out-of-market banks and bank holding companies that advertise or otherwise serve our markets, money market funds and other mutual funds, brokerage houses, and various other financial institutions. Additionally, we compete with insurance companies, leasing companies, regulated small loan companies, credit unions, governmental agencies and commercial entities offering financial services products.products, including nonbank lenders and so-called financial technology companies. Competition involves, among other things, efforts to retain current customers and to obtain new loans and deposits, the scope and typetypes of services offered, interest rates paid on deposits and charged on loans, as well as other aspects of banking. We also face direct competition from subsidiaries of bank holding companies that have far greater assets and resources than ours.

The Corporation and its banking and nonbanking subsidiaries are subject to extensive regulation and oversight both at the federal and state levels. The following is an overview of the statutory and regulatory framework that affects the business of the Corporation and our subsidiaries.

As a registered bank holding company under the BHC Act, we are regulated, supervised, and examined by the Federal Reserve. In connection with applicable requirements, bank holding companies file periodic reports and other information with the Federal Reserve. The BHC Act also governs the activities that are permissible for bank holding companies and their affiliates and permits the Federal Reserve, in certain circumstances, to issue cease and desist orders and other enforcement actions against bank holding companies and their nonbanking affiliates to correct and curtail unsafe or unsound banking practices. Under the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) and longstanding Federal Reserve policy, bank holding companies are required to act as a source of financial strength to each of their banking subsidiaries pursuant to which such holding company may be required to commit financial resources to support such subsidiaries in circumstances when, absent such requirements, they might not otherwise do.do so. The BHC Act further regulates holding company activities,

The BHC Act allows certain qualifying bank holding companies that elect treatment as “financial holding companies” to engage in activities that are financial in nature and that explicitly include the underwriting and sale of insurance. The Parent Company thus far has not elected to be treated as a financial holding company. Bank holding companies that have not elected such treatment generally must limit their activities to banking activities and activities that are closely related to banking.

Associated Bank and our nationally chartered trust company subsidiary are regulated, supervised and examined by the Office of the Comptroller of the Currency (the “OCC”).OCC. The OCC has primary supervisory and regulatory authority over the operations of Associated Bank and the Corporation’s national bank andCorporation's trust company subsidiaries. As part of this authority, the national bankAssociated Bank and our trust company subsidiaries are required to file periodic reports with the OCC and are subject to regulation, supervision and examination by the OCC. To support its supervisory function, the OCC has the authority to assess and charge fees on all national banks according to a set fee schedule. On November 25, 2019, the OCC announced that it will reduce the rates in all fee schedules by 10 percent for the 2020 calendar year, thus reducing the assessment fees that Associated Bank will pay in 2020.

We are required to obtain prior Federal Reserve approval before acquiring more than 5% of the voting shares, or substantially all of the assets, of a bank holding company, bank or savings association. In addition, the prior approval of the OCC is required for a national bank to merge with another bank or purchase the assets or assume the deposits of another bank. In determining whether to approve a proposed bank acquisition, federal bank regulators will consider, among other factors, the effect of the acquisition on competition, the public benefits expected to be received from the acquisition, the projected capital ratios and levels on a post-acquisition basis, and the acquiring institution’s record of addressing the credit needs of the communities it serves, including the needs of low and moderate income neighborhoods, consistent with the safe and sound operation of the bank, under the Community Reinvestment Act.CRA. See the “Risk Factors”Risk Factors section for a more extensive discussion of this topic.

The Parent Company is a legal entity separate and distinct from its bankingthe Bank and other nonbanking subsidiaries. A substantial portion of our revenuecash flow comes from dividends paid to us by Associated Bank. The OCC’s prior approval of the payment of dividends by Associated Bank to the Parent Company is required only if the total of all dividends declared by the Bank in any calendar year exceeds the sum of the Bank’s retained net income for that year and its retained net income for the preceding two calendar years, less any required transfers to surplus. Federal law also prohibits national banks from paying dividends that would be greater than the bank’s undivided profits after deducting statutory bad debt in excess of the bank’s allowance for loan losses. In addition, under the Federal Deposit Insurance Corporation Improvement Act (“FDICIA”),FDICIA, an insured depository institution, such as the Bank, is prohibited from making capital distributions, including the payment of dividends, if, after making such distribution, the institution would become “undercapitalized” (as such term is used in the FDICIA).

In addition, we and our banking subsidiarythe Bank are subject to various general regulatory policies and requirements relating to the payment of dividends, including requirements to maintain adequate capital above regulatory minimums. The appropriate federal regulatory authority is authorized to determine under certain circumstances relating to the financial condition of a bank or bank holding

company that the payment of dividends would be an unsafe or unsound practice and to prohibit payment thereof. Under the Dodd-Frank Act and the requirements of the FRB, the Corporation,Parent Company, as a bank holding company, is required to serve as a source of financial strength to the Bank and to commit resources to support the Bank. In addition, consistent with its “source of strength” policy, the FRB has stated that, as a matter of prudent banking, a bank holding company should not maintain a level of cash dividends to its shareholders that places undue pressure on the capital of its bank subsidiaries, or that can be funded only through additional borrowings or other arrangements that may undermine the bank holding company’s ability to serve as a source of strength. The appropriate federal regulatory authorities have indicated that paying dividends that deplete a bank’s capital base to an inadequate level would be an unsafe and unsound banking practice and that banking organizations should generally pay dividends only out of current operating earnings.

We are subject to various regulatory capital requirements both at the Parent Company and at the Bank level administered by the Federal Reserve and the OCC, respectively. Failure to meet minimum capital requirements could result in certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have an adverse material effect on our financial condition and results of operations. Under capital adequacy guidelines and the regulatory framework for prompt corrective action (described below), we must meet specific capital guidelines that involve quantitative measures of our assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting policies. Our capital amounts and classification are also subject to judgments by the regulators regarding qualitative components, risk weightings, and other factors. We have consistently maintained regulatory capital ratios at or above the well capitalized standards.

In July 2013, the Federal Reserve and the OCC issued final rules establishing a new comprehensive capital framework for U.S. banking organizations. These rules implemented certain provisions of the Dodd-Frank Act and a separate international framework established by the Basel Committee on Banking Supervision for the regulation of capital and liquidity, generally referred to as “Basel III.” The final rules seek to strengthen the components of regulatory capital, increase risk-based capital requirements, and make selected changes to the calculation of risk-weighted assets. The final rules, among other things:

In December 2019, the federal banking agencies issued a final rule on the capital treatment of HVCRE exposures which brought the regulatory definition of HVCRE exposure in line with the statutory definition of HVCRE ADC in the Economic Growth Act. The final rule also clarifies the capital adjustmentstreatment for loans that finance the development of land under the revised HVCRE exposure definition and deductions. Requirements to maintain higher levels ofestablishes the requirements for certain exclusions from HVCRE exposures capital could adversely impact our return on equity. treatment.

We believe we will continue to exceed all capital requirements necessary to be deemed "well-capitalized"“well-capitalized” for all regulatory purposes under these new rules on a fully phased-in basis. For further detail on capital and capital ratios see discussion under the Liquidity and Capital sections under Part II, Item 7, “Management’sManagement’s Discussion and Analysis of Financial Condition and Results of Operations,” sections, “Liquidity” and “Capital,” and under Part II, Item 8, “FinancialFinancial Statements and Supplementary Data,” Note 19 Regulatory Matters of the notes to consolidated financial statements.

On October 12, 2012,As part of the regulatory relief provided by the Economic Growth Act, the asset threshold requiring insured depository institutions to conduct and report to their primary federal bank regulatory agencies published final rules implementing theregulators annual company-run stress test requirements mandated bytests was raised from $10 billion to $250 billion in total consolidated assets and the Dodd-Frankrequirement was made “periodic” rather than annual. Upon enactment, the Economic Growth Act for U.S.also provided that bank holding companies under $100 billion in assets were no longer subject to stress testing requirements. The amended regulations also provide the Federal Reserve with discretion to subject bank holding companies with total consolidated assets of $10 billion to $50 billion. Under the rules, we are required to conduct annual company-run stress tests using different scenarios (baseline, adverse and severely adverse) provided annually by the Federal Reserve and the OCC, the primary federal regulator for the Bank. The stress test is designed to assess the potential impact of different scenarios on earnings, losses and capital over a set time period, with consideration given to certain factors, including the organization’s condition, risks, exposures, strategies and activities. The banking agencies have issued guidance on stress testing for banking organizations with more than $10$100 billion in total consolidated assets. Thisassets to enhanced supervision. In addition, Section 214 of the Economic Growth Act and its implementing regulation prohibit the federal banking agencies from requiring the Bank to assign a heightened risk weight to certain HVCRE ADC loans as previously required under the Basel III Capital Rules. Notwithstanding these regulatory amendments, the federal banking agencies indicated through interagency guidance outlines four “high-level” principles forthat the capital planning and risk management practices of institutions with total assets less than $100 billion would continue to be reviewed through the regular supervisory process. Although the Corporation will continue to monitor and stress test its capital consistent with the safety and soundness expectations of the federal regulators, the Corporation will no longer publish stress testing practices that regulators expect banking organizations to include in their stress testing framework. In particular, the stress testing framework should (i) include activities and exercises that are tailored to and sufficiently capture the banking organization’s exposures, activities and risks, (ii) employ multiple conceptually sound stress testing activities and approaches, (iii) be forward-looking and flexible, and (iv) be clear, actionable, well-supported, and used in the decision-making process.

The Federal Reserve, the OCC, and the CFPB have extensive supervisory authority over their regulated institutions, including, among other things, the power to compel higher reserves, the ability to assess civil money penalties, the ability to issue cease-and-desist or removal orders and the ability to initiate injunctive actions. In general, these enforcement actions may be initiated for violations of laws and regulations or for unsafe or unsound banking practices. Other actions or inactions by the Parent Company may provide the basis for enforcement action, including misleading or untimely reports.

“Well capitalized” institutions may generally operate without supervisory restriction. With respect to “adequately“Adequately capitalized” institutions such banks cannot normally pay dividends or make any capital contributions that would leave itthem undercapitalized; they cannot pay a management fee to a controlling person if, after paying the fee, itthey would be undercapitalized; and they cannot accept, renew or roll over any brokered deposit unless the bank has applied for and been granted a waiver by the FDIC.

The federal banking agencies are required to take action to restrict the activities of an “undercapitalized,” “significantly undercapitalized,” or “critically undercapitalized” insured depository institution. Any such bank must submit a capital restoration plan that is guaranteed by the parent holding company. Until such plan is approved, it may not increase its assets, acquire another institution, establish a branch or engage in any new activities, and generally may not make capital distributions.

In certain situations, a federal banking agency may reclassify a well-capitalized institution as adequately capitalized and may require an adequately capitalized or undercapitalized institution to comply with supervisory actions as if the institution were in the next lower category.

Institutions must file a capital restoration plan with the OCC within 45 days of the date it receives a notice from the OCC that it is “undercapitalized,” “significantly undercapitalized,” or “critically undercapitalized.” Compliance with a capital restoration plan must be guaranteed by a parent holding company. In addition, the OCC is permitted to take any one of a number of discretionary supervisory actions, including but not limited to the issuance of a capital directive and the replacement of senior executive officers and directors.

Finally, bank regulatory agencies have the ability to impose higher than normal capital requirements known as individual minimum capital requirements for institutions with a high-risk profile.

At December 31, 2016,2019, the Bank satisfied the capital requirements necessary to be deemed “well capitalized.” TheIn the event of a change to this status, the imposition of any of the measures described above could have a material adverse effect on the Corporation and on its profitability and operations. The Corporation’s shareholders do not have preemptive rights and, therefore, if the Corporation is directed by the OCC or the FDIC to issue additional shares of common stock, such issuance may result in dilution in shareholders’ percentage of ownership of the Corporation.

Associated Bank is a member of the FDIC and pays an insurance premium to the FDIC based upon its assessment rates on a quarterly basis. Deposits are insured up to applicable limits by the FDIC and such insurance is backed by the full faith and credit of the United States Government.

Under the Dodd-Frank Act, a permanent increase in deposit insurance was authorized to $250,000 per depositor, per insured depository institution for each account ownership category.

The Dodd-Frank Act also set a newthe minimum Deposit Insurance Fund ("DIF")DIF reserve ratio at 1.35% of estimated insured deposits. The FDIC is required to attain this ratio by September 30, 2020. The Dodd-Frank Act also required the FDIC to define the deposit insurance assessment base for an insured depository institution as an amount equal to the institution’s average consolidated total assets during the assessment period minus average tangible equity. The assessment rate schedule for larger institutions like Associated Bank (i.e., institutions with at least $10 billion in assets) differentiates between such large institutions by use of a “scorecard” that combines an institution’s CAMELS ratings with certain forward-looking financial information to measure the risk to the DIF. Pursuant to this “scorecard” method, two scores (a performance score and a loss severity score) will be combined and converted to an initial base assessment rate. The performance score measures an institution’s financial performance and ability to withstand stress. The loss severity score measures the relative magnitude of potential losses to the DIF in the event of the institution’s failure. Total scores are converted pursuant to a predetermined formula into an initial base assessment rate. Assessment rates range from 2.5 basis pointsbp to 45 basis points (“bp”)bp for large institutions.

The FDIC has the flexibility to adopt actual rates that are higher or lower than the total base assessment rates adopted without notice and comment, if certain conditions are met.

DIF-insured institutions pay a Financing Corporation (“FICO”)FICO assessment in order to fund the interest on bonds issued in the 1980s in connection with the failures in the thrift industry. The FICO assessment was computed on assets as required by the Dodd-Frank Act. These assessments will continuecontinued until the bonds maturematured in September 2019. The Corporation’s combined assessment rate for FDIC and FICO assessments was approximately 12 bp6 bps for 2016.2019.

The FDIC is authorized to conduct examinations of and require reporting by FDIC-insured institutions. It is also authorized to terminate a depository bank’s deposit insurance upon a finding by the FDIC that the bank’s financial condition is unsafe or unsound or that the institution has engaged in unsafe or unsound practices or has violated any applicable rule, regulation, order or condition enacted or imposed by the bank’s regulatory agency. The termination of deposit insurance for our national bank subsidiary would have a material adverse effect on our earnings, operations and financial condition.

The federal banking agencies have adopted the Interagency Guidelines for Establishing Standards for Safety and Soundness.Soundness (the “Guidelines”). The Guidelines establish certain safety and soundness standards for all depository institutions. The operational and managerial standards in the Guidelines relate to the following: (1) internal controls and information systems; (2) internal audit systems; (3) loan documentation; (4) credit underwriting; (5) interest rate exposure; (6) asset growth; (7) compensation, fees and benefits; (8) asset quality; and (9) earnings. Rather than providing specific rules, the Guidelines set forth basic compliance considerations and guidance with respect to a depository institution. Failure to meet the standards in the Guidelines, however, could result in a request by the OCC to one of the nationally chartered banks to provide a written compliance plan to demonstrate its efforts to come into compliance with such Guidelines. Failure to provide a plan or to implement a provided plan requires the appropriate federal banking agency to issue an order to the institution requiring compliance.

Transactions between our national banking subsidiary and its related parties or any affiliate are governed by Sections 23A and 23B of the Federal Reserve Act. An affiliate is any company or entity, which controls, is controlled by or is under common control with the bank. In a holding company context, at a minimum, the parent holding company of a national bank, and any companies that are controlled by such parent holding company, are affiliates of the bank. Generally, Sections 23A and 23B (i) limit the extent to which an institution or its subsidiaries may engage in “covered transactions” with any one affiliate to an amount equal to 10% of such institution’s capital stock and surplus, and contain an aggregate limit on all such transactions with all affiliates to an amount equal to 20% of such capital stock and surplus, and (ii) require that all such transactions be on terms substantially the same, or at least as favorable, to the institution or subsidiary as those provided to a nonaffiliate. The term “covered transaction” includes the making of loans, purchase of assets, issuance of a guarantee and similar types of transactions. Certain types of covered transactions must be collateralized according to a schedule set forth in the statute based on the type of collateral.

Certain transactions with our directors, officers or controlling persons are also subject to conflicts of interest regulations. Among other things, these regulations require that loans to such persons and their related interests be made on terms substantially the same as for loans to unaffiliated individuals and must not create an abnormal risk of repayment or other unfavorable features for the financial institution. See Note 4 Loans of the notes to consolidated financial statements in Part II, Item 8, “FinancialFinancial Statements and Supplementary Data,” for additional information on loans to related parties.

Our national bank subsidiary, Associated Bank is subject to periodic Community Reinvestment Act (“CRA”)CRA reviews by the OCC. The CRA does not establish specific lending requirements or programs for financial institutions and does not limit the ability of such institutions to develop products and services believed best-suited for a particular community. An institution’s CRA assessment may be used by its regulators in their evaluation of certain applications, including a merger, acquisition or the establishment of a branch office. An unsatisfactory rating may be used as the basis for denial of such an application.

On December 12, 2019, the FDIC and the OCC issued a proposed rule to modernize their respective agencies' regulations under the CRA. The proposed rule would (1) clarify which activities qualify for CRA credit and (2) require banks to identify an additional assessment area based on where they receive a significant portion of “Needstheir domestic retail products, thus creating two assessment areas: a deposit-based assessment area and a facility-based assessment area. The Federal Reserve chose not to Improve” for the period 2006-2010. The “Needs to Improve” rating restricts certain of our activities, including certain mergers and acquisitions and the establishment or relocation of Bank branches and certain other facilities.  The rating also resultedparticipate in the losscurrent proposed rulemaking which causes uncertainty as to the content and timing of expedited processingany final rule.

The Bank Secrecy Act (“BSA”),BSA, which is intended to require financial institutions to develop policies, procedures, and practices to prevent and deter money laundering, mandates that every national bank have a written, board-approved program that is reasonably designed to assure and monitor compliance with the BSA. The program must, at a minimum: (1) provide for a system of internal controls to assure ongoing compliance; (2) provide for independent testing for compliance; (3) designate an individual responsible for coordinating and monitoring day-to-day compliance; and (4) provide training for appropriate personnel. In addition, national banks are required to adopt a customer identification program as part of its BSA compliance program. National banks are also required to file Suspicious Activity ReportsSARs when they detect certain known or suspected violations of federal law or suspicious transactions related to a money laundering activity or a violation of the BSA. In May 2016, the regulations implementing the BSA were amended, effective May 2018, to explicitly include risk-based procedures for conducting ongoing customer due diligence to includeand procedures for understanding the nature and purpose of customer relationships for the purpose of developing a customer risk profile. In addition, FinCEN recently promulgated new customer due diligence and customer identification rules that require banks mustto identify and verify the identity of the beneficial owners of all legal entity customers (other than those that are excluded) at the time a new account is opened (other than

In addition to complying with the BSA, the Bank is subject to the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (the “Patriot Act”).Patriot Act. The Patriot Act is designed to deny terrorists and criminals the ability to obtain access to the United States’ financial system and has significant implications for depository institutions, brokers, dealers, and other businesses involved in the transfer of money. The Patriot Act mandates that financial service companies implement additional policies and procedures and take heightened measures designed to address any or all of the following matters: customer identification programs, money laundering, terrorist financing, identifying and reporting

suspicious activities and currency transactions, currency crimes, and cooperation between financial institutions and law enforcement authorities.

The new rule became effective on January 1, 2020, but banking entities of any size, includingwill not be required to comply with the Parent Company and Associated Bank. The Final Rules were effective Aprilnew rules until January 1, 2014, but the conformance period was extended2021. Although we will benefit from its statutory end date of July 21, 2014 until July 21, 2015. In addition, the Federal Reserve granted extensions until July 21, 2017 of the conformance period for banking entities to conform investments in and relationships with covered funds that were in place prior to December 31, 2013, and in December 2016 provided guidance allowing for additional extensionssignificantly reduced compliance obligations due to the level of our trading assets being below the $20 billion threshold, we will remain subject to the modified rules and requirements related to covered funds. Accordingly, we expect that the revised rule will reduce some of our compliance costs, but in the short term we may experience some costs in developing and implementing changes in conformance period for certain illiquid funds. The Corporation has evaluatedwith the implications of the Final Rules on its investments and does not expect any material financial implications.new rule.

In July 2010, the federal banking agencies issued Guidanceguidance on Sound Incentive Compensation Policiessound incentive compensation policies that applies to all banking organizations supervised by the agencies (thereby including both the Parent Company and the Bank). Pursuant to the guidance, to be consistent with safety and soundness principles, a banking organization’s incentive compensation arrangements should: (1) provide employees with incentives that appropriately balance risk and

Federal and applicable state banking laws also require us to take steps to protect consumers. Bank regulatory agencies are increasingly focusing attention on compliance with consumer protection laws and regulations. These laws include disclosures regarding truth in lending, truth in savings, and funds availability.

To promote fairness and transparency for mortgages, credit cards, and other consumer financial products and services, the Dodd-Frank Act established the CFPB. This agency is responsible for interpreting and enforcing federal consumer financial laws, as defined by the Dodd-Frank Act, that, among other things, govern the provision of deposit accounts along with mortgage origination and servicing. Some federal consumer financial laws enforced by the CFPB include the Equal Credit Opportunity Act, the Truth in Lending Act (“TILA”),TILA, the Truth in Savings Act, the Home Mortgage Disclosure Act, the Real Estate Settlement Procedures Act (“RESPA”), the Equal Credit Opportunity Act,RESPA, the Fair Debt Collection Practices Act, and the Fair Credit Reporting Act. The CFPB is also authorized to prevent any institution under its authority from engaging in an unfair, deceptive, or abusive act or practice in connection with consumer financial products and services.

Under TILA as implemented by Regulation Z, as amended by the CFPB effective January 10, 2014, mortgage lenders are required to make a reasonable and good faith determination based on verified and documented information that a consumer applying for a mortgage loan has a reasonable ability to repay the loan according to its terms. Mortgage lenders are required to determine consumers’ ability to repay in one of two ways. The first alternative requires the mortgage lender to consider the following eight underwriting factors when making the credit decision: (1) current or reasonably expected income or assets; (2) current employment status; (3) the monthly payment on the covered transaction; (4) the monthly payment on any simultaneous loan; (5) the monthly payment for mortgage-related obligations; (6) current debt obligations, alimony, and child support; (7) the monthly debt-to-income ratio or residual income; and (8) credit history. Alternatively, the mortgage lender can originate “qualified mortgages,” which are entitled to a presumption that the creditor making the loan satisfied the ability-to-repay requirements. In general, a “qualified mortgage” is a mortgage loan without negative amortization, interest-only payments, balloon payments, or terms exceeding 30 years. In addition, to be a qualified mortgage the points and fees paid by a consumer cannot exceed 3% of the total loan amount. Qualified mortgages that are “higher-priced” (e.g., subprime loans) garner a rebuttable presumption of compliance with the ability-to-repay rules, while qualified mortgages that are not “higher-priced” (e.g., prime loans) are given a safe harbor of compliance. The Corporation is predominantly an originator of compliant qualified mortgages.

Additionally, the CFPB has the authority to take supervisory and enforcement action against banks and other financial services companies under the agency’s jurisdiction that fail to comply with federal consumer financial laws. As an insured depository institution with total assets of more than $10 billion, the Bank is subject to the CFPB’s supervisory and enforcement authorities. The Dodd-Frank Act also permits states to adopt stricter consumer protection laws and state attorneys general to enforce consumer protection rules issued by the CFPB. As a result of these aspects of the Dodd-Frank Act, the Bank operates in a stringent consumer compliance environment. Therefore, the Bank is likely to incur additional costs related to consumer protection compliance, including but not limited to potential costs associated with CFPB examinations, regulatory and enforcement actions and consumer-oriented litigation, which is likely to increase as a result of the consumer protection provisions of the Dodd-Frank Act. The CFPB has been active in bringing enforcement actions against banks and other financial institutions to enforce consumer financial laws, and has developed a number of new enforcement theories and applications of these laws. OtherThe federal financial regulatory agencies, including the OCC and states attorneys general, also have become increasingly active in this area with respect to institutions over which they have jurisdiction. We have incurred and may in the future incur additional costs in complying with these requirements.

Pursuant to the Dodd-Frank Act, the FDIC has backup enforcement authority over a depository institution holding company, such as the Parent Company, if the conduct or threatened conduct of such holding company poses a risk to the DIF, although such authority may not be used if the holding company is generally in sound condition and does not pose a foreseeable and material risk to the DIF. The Dodd-Frank Act may have a material impact on the Corporation’s and the Bank’s operations, particularly through increased compliance costs resulting from possible future consumer and fair lending regulations. See the “Risk Factors”Risk Factors section for a more extensive discussion of this topic.

The Bank is also subject to a variety of other regulations with respect to the operation of its businesses, including but not limited to the Dodd-Frank Act, which among other restrictions placed limitations on the interchange fees charged for debit card transactions, TILA, Truth in Savings Act, Equal Credit Opportunity Act, Electronic Funds Transfer Act, Fair Housing Act, Home Mortgage Disclosure Act, Fair Debt Collection Practices Act, Fair Credit Reporting Act, Expedited Funds Availability (Regulation CC), Reserve Requirements (Regulation D), Insider Transactions (Regulation O), Privacy of Consumer Information (Regulation P), Margin Stock Loans (Regulation U), Right To Financial Privacy Act, Flood Disaster Protection Act, Homeowners Protection Act, Servicemembers Civil Relief Act, RESPA, Telephone Consumer Protection Act, CAN-SPAM Act, Children’s Online Privacy Protection Act, and the John Warner National Defense Authorization Act.

The laws and regulations to which we are subject are constantly under review by Congress, the federal regulatory agencies, and the state authorities. These laws and regulations could be changed drastically in the future, which could affect our profitability, our ability to compete effectively, or the composition of the financial services industry in which we compete.

Our earnings and growth, as well as the earnings and growth of the banking industry, are affected by the credit policies of monetary authorities, including the Federal Reserve. An important function of the Federal Reserve is to regulate the national supply of bank credit in order to combat recession and curb inflationary pressures. Among the instruments of monetary policy used by the Federal Reserve to implement these objectives are open market operations in U.S. government securities, changes in reserve requirements against member bank deposits, and changes in the Federal Reserve discount rate. These meansinstruments are used in varying combinations to influence overall growth of bank loans, investments, and deposits, and may also affect interest rates charged on loans or paid for deposits. The monetary policies of the Federal Reserve authorities have had a significant effect on the operating results of commercial banks in the past and are expected to continue to have such an effect in the future.

In view of changing conditions in the national economy and in money markets, as well as the effect of credit policies by monetary and fiscal authorities, including the Federal Reserve, it is difficult to predict the impact of possible future changes in interest rates, deposit levels, and loan demand, or their effect on our business and earnings or on the financial condition of our various customers.

In addition to regulation, supervision and examination by federal banking agencies, the Corporation and certain of its subsidiaries, including those that engage in securities brokerage, dealing and investment advisory activities, are subject to other federal and applicable state securities laws and regulations, and to supervision and examination by other regulatory authorities, including the SEC, the Financial Industry Regulatory Authority (“FINRA”), the New York Stock Exchange (“NYSE”), the Department of Labor (“DOL”)FINRA, NYSE, DOL and others. In particular,Significantly, in June 2018 the U.S. Court of Appeals issued a mandate vacating the DOL’s “fiduciary rule” and related prohibited transaction exemptions. As a result, although the Bank may have taken certain measures to comply with the rule on a transitional basis, the Bank’s securities brokerage and investment advisory services and activities will no longer be affected.

Separately, in June 2019, pursuant to the Dodd-Frank Act, the SEC adopted Regulation Best Interest, which, among other things, establishes a new standard of conduct for a broker-dealer to act in the best interest of a retail customer when making a recommendation of any securities transaction or investment strategy involving securities to such customer. The new rule requires us to review and possibly modify our compliance activities, which is causing us to incur some additional costs. In addition, state laws that impose a fiduciary duty also may be impacted by final rules issued by the DOL in April 2016, which are being phased into effect between June 2016 and January 2018.require monitoring, as well as require that we undertake additional compliance measures. In addition, the Bank’s insurance agency subsidiary is also subject to regulation and supervision in the various states in which it operates.

An investment in our common stock is subject to risks inherent to our business. The material risks and uncertainties that management believes affect us are described below. Before making an investment decision, you should carefully consider the risks and uncertainties described below, together with all of the other information included or incorporated by reference herein. The risks and uncertainties described below are not the only ones facing us.

If any of the events described in the risk factors should actually occur, our financial condition and results of operations could be materially and adversely affected. If this were to happen, the value of our securities could decline significantly, and you could lose all or part of your investment.

On December 21, 2018, the regulatory agencies approved a final rule modifying their regulatory capital rules and providing an option to phase in over a period of three years the day-one regulatory capital effects of the CECL model. The final rule also revises the agencies' other rules to reflect the update to the accounting standards. The final rule became effective on April 1, 2019. Additionally, proposed guidance clarifying the final rule was issued in October 2019. The proposed guidance, when effective, will clarify the state of existing agency guidance and describe the appropriate CECL methodology for determining allowances for credit losses on specific assets, including net investments in leases, impaired available-for-sale debt securities, etc. The proposed guidance will become effective when each institution adopts the new standards required to materially increase our level of allowance for loan losses for any reason, such increase could adversely affect our business, financial condition and results of operations.by the FASB.

The new CECL standard will become effective for us for fiscal years beginning after December 15, 2019 and for interim periods within those fiscal years. We are currently evaluating the impact the CECL model will have on our accounting, but we expect to recognize a one-time cumulative-effect adjustment to our allowance for loan

losses as of the beginning of the first reporting period in which we adopt the new standard, is effective, consistent with regulatory expectations set forth in interagency guidance issued at the end of 2016. We cannot yet determineincurred transition costs and also expect to incur ongoing costs in maintaining the magnitudeadditional CECL models and methodology along with acquiring forecasts used within the models, and that the methodology will result in increased capital costs upon initial adoption as well as over time. The impact at adoption is expected to have an after tax impact of any such one-time cumulative adjustment or$70 million to $80 million decrease in the opening stockholders' equity balance and a corresponding 21bps to 24bps decrease to the tangible common equity ratio. See Note 1 Summary of Significant Accounting Policies of the overallnotes to consolidated financial statements for additional information on the Corporation's impact of the new standard on our financial condition or results of operations.adoption.

Although management believes it has implemented effective asset and liability management strategies, including the potential use of derivatives as hedging instruments, to reduce the potential effects of changes in interest rates on our results of operations, any substantial, unexpected, prolonged change in market interest rates could have a material adverse effect on our financial condition and results of operations. Also, our interest rate risk modeling techniques and assumptions likely may not fully predict or capture the impact of actual interest rate changes on our balance sheet.

When interest rates fall, borrowers are more likely to prepay their mortgage loans by refinancing them at a lower rate. As the likelihood of prepayment increases, the fair value of our residential mortgage-related securities and MSRs can decrease. Each quarter we evaluate our residential mortgage-related securities and MSRs for impairment. If temporary impairment exists, we establish a valuation allowance for the MSRs through a charge to earnings for the amount the carrying amount exceeds fair value. We also evaluate our MSRs for other-than-temporary impairment. If we determine that other-than-temporary impairment exists, we will recognize a direct write-down of the carrying value of the MSRs.

involving the theft of sensitive and confidential information, hackers have engaged in attacks against large financial institutions, particularly denial of service attacks, designed to disrupt key business services, such as customer-facing web sites. WeBecause the methods of cyber-attacks change frequently or, in some cases, are not recognized until launch, we are not able to anticipate or implement effective preventive measures against all possible security breaches and the probability of these types.a successful attack cannot be predicted. Although we employ detection and response mechanisms designed to contain and mitigate security incidents, early detection may be thwarted by persistent sophisticated attacks and malware designed to avoid detection.

We also face risks related to cyber-attacks and other security breaches in connection with card transactions that typically involve the transmission of sensitive information regarding our customers through various third parties. Some of these parties have in the past been the target of security breaches and cyber-attacks, and because the transactions involve third parties and environments that we do not control or secure, future security breaches or cyber-attacks affecting any of these third parties could impact us through no fault of our own, and in some cases we may have exposure and suffer losses for breaches or attacks relating to them. We also rely on numerous other third party service providers to conduct other aspects of our business operations and face similar risks relating to

Any successful cyber-attack or other security breach involving the misappropriation, loss or other unauthorized disclosure of confidential customer information or that compromises our ability to function could severely damage our reputation, erode confidence in the security of our systems, products and services, expose us to the risk of litigation and liability, disrupt our operations and have a material adverse effect on our business. Any successful cyber-attack may also subject the Corporation to regulatory investigations, litigation or enforcement, or require the payment of regulatory fines or penalties or undertaking costly remediation efforts with respect to third parties affected by a cyber security incident, all or any of which could adversely affect the Corporation’s business, financial condition or results of operations and damage its reputation.

Third party vendors provide key components of our business infrastructure, such as internet connections, network access and core application processing. While we have selected these third party vendors carefully, we do not control their actions. Any problems caused by these third parties, including as a result of their not providing us their services for any reason or their performing their services poorly, could adversely affect our ability to deliver products and services to our customers and otherwise to conduct our business. Replacing these third party vendors could also entail significant delay and expense.

From time to time the FASB and the SEC change the financial accounting and reporting standards or the interpretation of those standards that govern the preparation of our external financial statements. These changes are beyond our control, can be hard to predict and could materially impact how we report our results of operations and financial condition. We could be required to apply a new or revised standard retroactively, resulting in our restating prior period financial statements in material amounts.

Under current accounting standards, goodwill is not amortized but, instead, is subject to impairment tests on at least an annual basis or more frequently if an event occurs or circumstances change that reduce the fair value of a reporting unit below its carrying amount. A decline in our stock price or occurrence of a triggering event following any of our quarterly earnings releases and prior to the filing of the periodic report for that period could, under certain circumstances, cause us to perform a goodwill impairment test and result in an impairment charge being recorded for that period which was not reflected in such earnings release. During 2016,2019, the annual impairment test conducted in May indicated that the estimated fair value of all of the

Corporation’s reporting units exceeded the carrying value. In the event that we conclude that all or a portion of our goodwill may be impaired, a non-cash charge for the amount of such impairment would be recorded to earnings. Such a charge would have no impact on tangible capital. At December 31, 2016,2019, we had goodwill of $972 million,$1.2 billion, which representing approximately 31%30% of stockholders’ equity.

In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. Assessing the need for, or the sufficiency of, a valuation allowance requires management to evaluate all available evidence, both negative and positive, including the recent trend of quarterly earnings. Positive evidence necessary to overcome the negative evidence includes whether future taxable income in sufficient amounts and character within the carryback and carryforward periods is available under the tax law, including the use of tax planning strategies. When negative evidence (e.g., cumulative losses in recent years, history of operating loss or tax credit carryforwards expiring unused) exists, more positive evidence than negative evidence will be necessary. The Corporation has concluded that based on the level of positive evidence, it is more likely than not that the deferred tax asset will be realized. At December 31, 2016, net deferred tax assets were approximately $52 million.

The impact of each of these impairment matters could have a material adverse effect on our business, results of operations, and financial condition.

In addition, as customer preferences and expectations continue to evolve, technology has lowered barriers to entry and made it possible for nonbanks to offer products and services traditionally provided by banks, such as automatic transfer and automatic payment systems. In addition, some of the largest technology firms are engaging in joint ventures with the largest banks to provide and / or expand financial service offerings with a technological sophistication and breadth of marketing that smaller institutions do not have. Many of our competitors have fewer regulatory constraints and may have lower cost structures. Additionally, due to their size, many competitors may be able to achieve economies of scale and, as a result, may offer a broader range of products and services as well as better pricing for those products and services than we can.

Our ability to compete successfully depends on a number of factors, including, among other things:

Failure to perform in any of these areas could significantly weaken our competitive position, which could adversely affect our growth and profitability, which, in turn, could have a material adverse effect on our financial condition and results of operations.

Acquiring other banks, businesses, or branches involves potential adverse impact to our financial results and various other risks commonly associated with acquisitions, including, among other things:

Acquisitions also involve operational risks and uncertainties, and acquired companies may have unknown or contingent liabilities, exposure to unexpected asset quality problems that require write-downs or write-offs (as well as restructuring and impairment or other charges), difficulty retaining key employees and customers and other issues that could negatively affect our business. We may not be able to realize any projected cost savings, synergies or other benefits associated with any such acquisition we complete. Acquisitions typically involve the payment of a premium over book and market values and, therefore, some dilution of our tangible book value and net income per common share may occur in connection with any future transaction. Failure to successfully integrate the entities we acquire into our existing operations could increase our operating costs significantly and have a material adverse effect on our business, financial condition, and results of operations.

In addition, in September 2016, the CFPB and OCC entered into a consent order with a large national bank alleging widespread improper sales practices, which prompted the federal bank regulatory agencies to conduct a horizontal review of sales practices throughout the banking industry. The elevated attention likely will resulthas resulted in continued

General market fluctuations, industry factors, and general economic and political conditions and events, such as economic slowdowns or recessions, interest rate changes, or credit loss trends, could also cause our securities prices to decrease regardless of our operating results.
