Competition

We compete with other banks and financial services companies such as savings and loans, credit unions, and finance and trust companies, as well as mortgage banking companies, automobile and equipment financing companies (including captive automobile finance companies), insurance companies, mutual funds, investment advisors, and brokerage firms, both within and outside of our primary market areas. Internet companies are also providing nontraditional, but increasingly strong, competition for our borrowers, depositors, and other customers.

We compete for loans primarily on the basis of a combination of value and service by building customer relationships as a result of addressing our customers’ entire suite of banking needs, demonstrating expertise, and providing convenience to our customers. We also consider the competitive pricing pressures in each of our markets.

We compete for deposits similarly on a basis of a combination of value and service and by providing convenience through a banking network of branches and ATMs within our markets and our website at www.huntington.com. We have also instituted customer friendly practices, such as our 24-Hour Grace^® account feature, which gives customers an additional business day to cover overdrafts to their consumer account without being charged overdraft fees.

The table below shows our competitive ranking and market share based on deposits of FDIC-insured institutions as of June 30, 2013, in the top 10 metropolitan statistical areas (MSA) in which we compete:

Source: FDIC.gov, based on June 30, 2013 survey.

Many of our nonfinancial institution competitors have fewer regulatory constraints, broader geographic service areas, greater capital, and, in some cases, lower cost structures. In addition, competition for quality customers has intensified as a result of changes in regulation, advances in technology and product delivery systems, consolidation among financial service providers, bank failures, and the conversion of certain former investment banks to bank holding companies.

Regulatory Matters

We are subject to regulation by the SEC, the Federal Reserve, the OCC, the CFPB, and other federal and state regulators.

Because we are a public company, we are subject to regulation by the SEC. The SEC has established five categories of issuers for the purpose of filing periodic and annual reports. Under these regulations, we are considered to be a large accelerated filer and, as such, must comply with SEC accelerated reporting requirements.

We are a bank holding company and are qualified as a financial holding company with the Federal Reserve. We are subject to examination and supervision by the Federal Reserve pursuant to the Bank Holding Company Act. We are required to file reports and other information regarding our business operations and the business operations of our subsidiaries with the Federal Reserve.

Table of Contents

The Federal Reserve maintains a bank holding company rating system that emphasizes risk management, introduces a framework for analyzing and rating financial factors, and provides a framework for assessing and rating the potential impact of non-depository entities of a holding company on its subsidiary depository institution(s). The ratings assigned to us, like those assigned to other financial institutions, are confidential and may not be disclosed, except to the extent required by law.

The Federal Reserve utilizes an updated framework for the consolidated supervision of large financial institutions, including bank holding companies with consolidated assets of $50 billion or more. The objectives of the framework are to enhance the resilience of a firm, lower the probability of its failure, and reduce the impact on the financial system in the event of an institution’s failure. With regard to resiliency, each firm is expected to ensure that the consolidated organization and its core business lines can survive under a broad range of internal or external stresses. This requires financial resilience by maintaining sufficient capital and liquidity, and operational resilience by maintaining effective corporate governance, risk management, and recovery planning. With respect to lowering the probability of failure, each firm is expected to ensure the sustainability of its critical operations and banking offices under a broad range of internal or external stresses. This requires, among other things, effective resolution planning that addresses the complexity and the interconnectivity of the firm’s operations.

The Bank, which is chartered by the OCC, is a national bank and our only bank subsidiary. It is subject to examination and supervision by the OCC and also by the CFPB, which was established by the Dodd-Frank Act in 2010. Our nonbank subsidiaries are also subject to examination and supervision by the Federal Reserve or, in the case of nonbank subsidiaries of the Bank, by the OCC. All subsidiaries are subject to examination and supervision by the CFPB to the extent they offer any consumer financial products or services. Our subsidiaries are subject to examination by other federal and state agencies, including, in the case of certain securities and investment management activities, regulation by the SEC and the Financial Industry Regulatory Authority.

The Bank is subject to affiliate transaction restrictions under federal law, which limit certain transactions generally involving the transfer of funds by a bank or its subsidiaries to its parent corporation or any nonbank subsidiary of its parent corporation, whether in the form of loans, extensions of credit, investments, or asset purchases, or otherwise undertaking certain obligations on behalf of such affiliates. See also the Volcker Rule discussion below for additional affiliate transaction restrictions.

Legislative and regulatory reforms continue to have significant impacts throughout the financial services industry.

The Dodd-Frank Act, enacted in 2010, is complex and broad in scope and several of its provisions are still being implemented. The Dodd-Frank Act established the CFPB, which has extensive regulatory and enforcement powers over consumer financial products and services, and the Financial Stability Oversight Council, which has oversight authority for monitoring and regulating systemic risk. In addition, the Dodd-Frank Act altered the authority and duties of the federal banking and securities regulatory agencies, implemented certain corporate governance requirements for all public companies including financial institutions with regard to executive compensation, proxy access by shareholders, and certain whistleblower provisions, and restricted certain proprietary trading and hedge fund and private equity activities of banks and their affiliates. The Dodd-Frank Act also required the issuance of numerous implementing regulations, many of which have not yet been issued. The regulations will continue to take effect over several more years, continuing to make it difficult to anticipate the overall impact to us, our customers, or the financial industry in general.

In mid-January 2013, the CFPB issued eight final regulations governing mainly consumer mortgage lending. The first of these rules was issued on January 10, 2013, and included the ability to repay and qualified mortgage rule. This rule imposes additional requirements on lenders, including rules designed to require lenders to ensure borrowers’ ability to repay their mortgage and took effect January 10, 2014. The same day, the CFPB also finalized a rule on escrow accounts for higher priced mortgage loans and a rule expanding the scope of the high-cost mortgage provision in the Truth in Lending Act. On January 17, 2013, the CFPB issued its final rules implementing provisions of the Dodd-Frank Act that relate to mortgage servicing, which took effect on January 10, 2014. On January 18, 2013, the CFPB issued a final appraisal rule under the Equal Credit Opportunity Act and six agencies including the CFPB, FRB, OCC, FDIC, NCUA, and FHFA issued an interagency rule on appraisals for higher-priced mortgage loans. On November 20, 2013, the CFPB issued its final rule on integrated mortgage disclosures under the Truth in Lending Act and the Real Estate Settlement Procedures Act, for which compliance is required by August 1, 2015. We are evaluating these integrated mortgage disclosure rules to determine their impact on the Bank and its affiliates.

During the 2013 first quarter, the CFPB provided guidance on fair lending practices to indirect automobile lenders with recommendations to ensure compliance with fair lending laws.

Recently, banking regulatory agencies have increasingly used a general consumer protection statute to address unethical or otherwise bad business practices that may not necessarily fall directly under the purview of a specific banking or consumer finance law. Prior to the Dodd-Frank Act, there was little formal guidance to provide insight to the parameters for compliance with the “unfair or deceptive acts or practices” (UDAP) law. However, the UDAP provisions have been expanded under the Dodd-Frank Act to apply to “unfair, deceptive or abusive acts or practices”, which has been delegated to the CFPB for supervision.

Large bank holding companies and national banks are required to submit annual capital plans to the Federal Reserve and OCC, respectively and conduct stress tests.

The Federal Reserve published final amendments to Regulation Y to require large bank holding companies to submit capital plans to the Federal Reserve on an annual basis and to require such bank holding companies to obtain approval from the Federal Reserve under certain circumstances before making a capital distribution. This rule applies to us and all other bank holding companies with $50 billion or more of total consolidated assets.

A large bank holding company’s capital plan must include an assessment of the expected uses and sources of capital over at least the next nine quarters, a description of all planned capital actions over the planning horizon, a detailed description of the entity’s process for assessing capital adequacy, the entity’s capital policy, and a discussion of any expected changes to the banking holding company’s business plan that are likely to have a material impact on the firm’s capital adequacy or liquidity. The planning horizon for the most recent capital planning and stress testing cycle encompasses the 2013 fourth quarter through the 2015 fourth quarter as was submitted in our capital plan in January 2014. Rules to implement the Basel III capital reforms in the United States were finalized in July 2013, and will be phased-in beginning in 2015 for us under the standardized approach. As such, the most recent CCAR cycle, which began October 1, 2013, overlaps with the implementation of the Basel III capital reforms based on the required nine quarter projection horizon. The interim final rules clarify that banking organizations with $50 billion or more in total consolidated assets, including us, must incorporate the revised capital framework into the capital planning projections and into the stress tests required under the Dodd-Frank Act. The rule also clarifies that for the upcoming cycle, capital adequacy at large banking organizations, including us, would continue to be assessed against a minimum 5 percent tier 1 common ratio as calculated by the Federal Reserve.

Capital plans for 2014 were required to be submitted by January 6, 2014. The Federal Reserve will either object to a capital plan, in whole or in part, or provide a notice of non-objection no later than March 31, 2014, for plans submitted by the January 6, 2014 submission date. If the Federal Reserve objects to a capital plan, the bank holding company may not make any capital distributions other than those with respect to which the Federal Reserve has indicated its non-objection. While we can give no assurances as to the outcome or specific interactions with the regulators, based on the Capital Plan we submitted on January 5, 2014, we believe we have a strong capital position and that our capital adequacy process is robust.

In addition to the CCAR submission, section 165 of the Dodd-Frank Act requires that national banks, like The Huntington National Bank, conduct annual stress tests for submission in January 2014. The results of the stress tests will provide the OCC with forward-looking information that will be used in bank supervision and will assist the agency in assessing a company’s risk profile and capital adequacy. We submitted our stress test results to the OCC on January 6, 2014.

The regulatory capital rules indicate that common stockholders’ equity should be the dominant element within Tier 1 capital and that banking organizations should avoid overreliance on non-common equity elements. Under the Dodd-Frank Act, the ratio of Tier 1 common equity to risk-weighted assets became significant as a measurement of the predominance of common equity in Tier 1 capital and an indication of the quality of capital.

Final rules have been issued to implement the Volcker Rule.

On December 10, 2013, the Federal Reserve, the OCC, the FDIC, the CFTC and the SEC issued final rules to implement the Volcker Rule contained in section 619 of the Dodd-Frank Act, generally to become effective on July 21, 2015. The Volcker Rule prohibits an insured depository institution and its affiliates (referred to as “banking entities”) from: (i) engaging in “proprietary trading” and (ii) investing in or sponsoring certain types of funds (“covered funds”) subject to certain limited exceptions. These prohibitions impact the ability of U.S. banking entities to provide investment management products and services that are competitive with nonbanking firms generally and with non-U.S. banking organizations in overseas markets. The rule also effectively prohibits short-term trading strategies by any U.S. banking entity if those strategies involve instruments other than those specifically permitted for trading.

The final Volcker Rule regulations do provide certain exemptions allowing banking entities to continue underwriting, market-making and hedging activities and trading certain government obligations, as well as various exemptions and exclusions from the definition of “covered funds”. The level of required compliance activity depends on the size of the banking entity and the extent of its trading. CEOs of larger banking entities, including Huntington, will have to attest annually in writing that their organization has in place processes to establish, maintain, enforce, review, test and modify compliance with the Volcker Rule regulations. Banking entities with significant permitted trading operations will have to report certain quantitative information, beginning between June 30, 2014 and December 31, 2016, depending on the size of the banking entity’s trading assets and liabilities.

On January 14, 2014, the five federal agencies approved an interim final rule to permit banking entities to retain interests in certain collateralized debt obligations backed primarily by trust preferred securities from the investment prohibitions of the Volcker Rule. Under the interim final rule, the agencies permit the retention of an interest in or sponsorship of covered funds by banking entities if certain qualifications are met. In addition, the agencies released a non-exclusive list of issuers that meet the requirements of

the interim final rule. At December 31, 2013, we had investments in ten different pools of trust preferred securities. Eight of our pools are included in the list of non-exclusive issuers. We have analyzed the other two pools that were not included on the list and believe that we will continue to be able to own these investments under the final Volcker Rule regulations.

The rules effecting debit card interchange fees under the Durbin Amendment, which became effective on October 1, 2011, have negatively impacted our electronic banking income.

The Durbin Amendment, which was section 1075 of the Dodd-Frank Act, required the Federal Reserve to establish a cap on the rate merchants pay banks for electronic clearing of debit transactions (i.e. the interchange rate). The Federal Reserve issued final rules, effective October 1, 2011, for establishing standards, including a cap, for debit card interchange fees and prohibiting network exclusivity arrangements and routing restrictions. The final rule established standards for assessing whether debit card interchange fees received by debit card issuers were reasonable and proportional to the costs incurred by issuers for electronic debit transactions. Under the final rule, the maximum permissible interchange fee that an issuer may receive for an electronic debit transaction is the sum of 21 cents per transaction, a 1 cent fraud prevention adjustment, and 5 basis points multiplied by the value of the transaction. As a result of implementing this lower debit card interchange fee structure, our electronic banking income was negatively impacted by over $55 million in 2012 when compared to 2011.

On July 31, 2013, the Federal District Court in the District of Columbia issued a ruling in a lawsuit filed by a merchant group challenging the validity of the Federal Reserve’s final rule under the Durbin Amendment. The Court ruling vacated the provisions of the Federal Reserve’s final rule relating to standards for debit card interchange fees and the provision dealing with network non-exclusivity, but stayed its action until further briefing on issues identified by the Court. Eventually, the District Court’s Ruling was appealed to the Federal Circuit Court of Appeals for the District of Columbia, where the case is currently pending. If the Court of Appeals rules in favor of the merchants, the Federal Reserve will likely be required to provide even more stringent caps on debit interchange fees, which could adversely impact all banks that issue debit cards, including us, and which could result in an industry-wide retraction of debit card products and replacement with other card products not subject to the Durbin Amendment. The Federal Reserve and a banking trade organization are submitting briefs arguing that the Court of Appeals should overrule the District Court and uphold the Federal Reserve’s final rule under the Durbin Amendment. Oral argument before the Court of Appeals was held on January 17, 2014, and an expedited ruling is anticipated.

There are restrictions on our ability to pay dividends.

Dividends from the Bank to the parent company are the primary source of funds for payment of dividends to our shareholders. However, there are statutory limits on the amount of dividends that the Bank can pay to the holding company. Regulatory approval is required prior to the declaration of any dividends in an amount greater than its undivided profits or if the total of all dividends declared in a calendar year would exceed the total of its net income for the year combined with its retained net income for the two preceding years, less any required transfers to surplus or common stock. As a result of the deficit position of its undivided profits, prior to December 31, 2013, the Bank could not have declared and paid any cash dividends to the parent company without regulatory approval.

Since the first quarter of 2008, the Bank has made a capital reduction each quarter to enable payment of periodic dividends to shareholders outside the Bank’s consolidated group on preferred and common stock of its REIT and capital financing subsidiaries. We anticipate that those subsidiaries, and the Bank will be able to resume normal dividend payments during the first half of 2014.

If, in the opinion of the applicable regulatory authority, a bank under its jurisdiction is engaged in, or is about to engage in, an unsafe or unsound practice, such authority may require, after notice and hearing, that such bank cease and desist from such practice. Depending on the financial condition of the Bank, the applicable regulatory authority might deem us to be engaged in an unsafe or unsound practice if the Bank were to pay dividends. The Federal Reserve and the OCC have issued policy statements that provide that insured banks and bank holding companies should generally only pay dividends out of current operating earnings. Additionally, the Federal Reserve may prohibit bank holding companies from making any capital distributions, including payment of preferred and common dividends, if the Federal Reserve objects to the annual capital plan.

We are subject to the current capital requirements mandated by the Federal Reserve and final capital rules to implement Basel III that were adopted in July 2013.

The Federal Reserve sets risk-based capital ratio and leverage ratio guidelines for bank holding companies. Under the guidelines and related policies, bank holding companies must maintain capital sufficient to meet both a risk-based asset ratio test and a leverage ratio test on a consolidated basis. The risk-based ratio is determined by allocating assets and specified off-balance sheet commitments into four weighted categories, with higher weighting assigned to categories perceived as representing greater risk. The risk-based ratio represents total capital divided by total risk-weighted assets. The leverage ratio is core capital divided by total assets adjusted as specified in the guidelines. The Bank is subject to substantially similar capital requirements.

On July 2, 2013, the Federal Reserve voted to adopt final capital rules implementing Basel III requirements for U.S. Banking organizations. The final rules establish an integrated regulatory capital framework and will implement in the United States the Basel III regulatory capital reforms from the Basel Committee on Banking Supervision and certain changes required by the Dodd-Frank Act. Under the final rule, minimum requirements will increase for both the quantity and quality of capital held by banking organizations. Consistent with the international Basel framework, the final rule includes a new minimum ratio of common equity tier 1 capital (Tier I Common) to risk-weighted assets and a Tier 1 Common capital conservation buffer of 2.5% of risk-weighted assets that will apply to all supervised financial institutions. The rule also raises the minimum ratio of tier 1 capital to risk-weighted assets and includes a minimum leverage ratio of 4% for all banking organizations. These new minimum capital ratios will become effective for us on January 1, 2015, and will be fully phased-in on January 1, 2019.

Following are the Basel III regulatory capital levels that we must satisfy to avoid limitations on capital distributions and discretionary bonus payments during the applicable transition period, from January 1, 2015 until January 1, 2019:

The final rule emphasizes Tier 1 Common capital, the most loss-absorbing form of capital, and implements strict eligibility criteria for regulatory capital instruments. The final rule also improves the methodology for calculating risk-weighted assets to enhance risk sensitivity. Banks and regulators use risk weighting to assign different levels of risk to different classes of assets.

We have evaluated the impact of the Basel III final rule on our regulatory capital ratios and estimate a reduction of approximately 60 basis points to our Basel I Tier I Common risk-based capital ratio based on our June 30, 2013 balance sheet composition. The estimate is based on management’s current interpretation, expectations, and understanding of the final U.S. Basel III rules. We anticipate that our capital ratios, on a Basel III basis, will continue to exceed the well capitalized minimum capital requirements. We are evaluating options to mitigate the capital impact of the final rule prior to its effective implementation date.

Based on our review of the Basel III final rule, it is likely that when Basel III becomes effective, the HPCI Class C preferred securities will no longer constitute Tier 1 capital for us or the Bank. As such, we determined that a “regulatory capital event” had occurred, based on an opinion of counsel rendered by a law firm experienced in such matters, and the HPCI board of directors determined to redeem the outstanding Class C preferred securities. HPCI redeemed all $50 million of the Class C preferred securities on December 31, 2013. The holders of such securities received the redemption price of $25.00 per share.

Based on the final Basel III rule, banking organizations with more than $15 billion in total consolidated assets are required to phase-out of additional tier 1 capital any non-qualifying capital instruments (such as trust preferred securities and cumulative preferred shares) issued before September 12, 2010. We will begin the additional tier I capital phase-out our trust preferred securities in 2015, but will be able to include these instruments in Tier II capital as a non-advanced approaches institution.

Generally, under the currently applicable guidelines, a financial institution’s capital is divided into two tiers. Institutions that must incorporate market risk exposure into their risk-based capital requirements may also have a third tier of capital in the form of restricted short-term subordinated debt. These tiers are:

The Federal Reserve and the other federal banking regulators require that all intangible assets (net of deferred tax), except originated or purchased MSRs, nonmortgage servicing assets, and purchased credit card relationships intangible assets, be deducted from Tier 1 capital. However, the total amount of these items included in capital cannot exceed 100% of its Tier 1 capital.

Under the risk-based guidelines to remain adequately-capitalized, financial institutions are required to maintain a total risk-based capital ratio of 8%, with 4% being Tier 1 risk-based capital. The appropriate regulatory authority may set higher capital requirements when they believe an institution’s circumstances warrant.

Table of Contents

Under the leverage guidelines, financial institutions are required to maintain a Tier 1 leverage ratio of at least 3%. The minimum ratio is applicable only to financial institutions that meet certain specified criteria, including excellent asset quality, high liquidity, low interest rate risk exposure, and the highest regulatory rating. Financial institutions not meeting these criteria are required to maintain a minimum Tier 1 leverage ratio of 4%.

Failure to meet applicable capital guidelines could subject the financial institution to a variety of enforcement remedies available to the federal regulatory authorities. These include limitations on the ability to pay dividends, the issuance by the regulatory authority of a directive to increase capital, and the termination of deposit insurance by the FDIC. In addition, the financial institution could be subject to the measures described below under Prompt Corrective Action as applicable to under-capitalized institutions.

The risk-based capital standards of the Federal Reserve, the OCC, and the FDIC specify that evaluations by the banking agencies of a bank’s capital adequacy will include an assessment of the exposure to declines in the economic value of a bank’s capital due to changes in interest rates. These banking agencies issued a joint policy statement on interest rate risk describing prudent methods for monitoring such risk that rely principally on internal measures of exposure and active oversight of risk management activities by senior management.

FDICIA requires federal banking regulatory authorities to take Prompt Corrective Action with respect to depository institutions that do not meet minimum capital requirements. For these purposes, FDICIA establishes five capital tiers: well-capitalized, adequately-capitalized, under-capitalized, significantly under-capitalized, and critically under-capitalized.

Throughout 2013, our regulatory capital ratios and those of the Bank were in excess of the levels established for well-capitalized institutions. An institution is deemed to be well-capitalized if it has a total risk-based capital ratio of 10% or greater, a Tier 1 risk-based capital ratio of 6% or greater, and a Tier 1 leverage ratio of 5% or greater and is not subject to a regulatory order, agreement, or directive to meet and maintain a specific capital level for any capital measure.

FDICIA generally prohibits a depository institution from making any capital distribution, including payment of a cash dividend or paying any management fee to its holding company, if the depository institution would become under-capitalized after such payment. Under-capitalized institutions are also subject to growth limitations and are required by the appropriate federal banking agency to submit a capital restoration plan. If any depository institution subsidiary of a holding company is required to submit a capital restoration plan, the holding company would be required to provide a limited guarantee regarding compliance with the plan as a condition of approval of such plan.

Depending upon the severity of the under capitalization, the under-capitalized institutions may be subject to a number of requirements and restrictions, including orders to sell sufficient voting stock to become adequately-capitalized, requirements to reduce total assets, cessation of receipt of deposits from correspondent banks, and restrictions on making any payment of principal or interest on their subordinated debt. Critically under-capitalized institutions are subject to appointment of a receiver or conservator within 90 days of becoming so classified.

Under FDICIA, a depository institution that is not well-capitalized is generally prohibited from accepting brokered deposits and offering interest rates on deposits higher than the prevailing rate in its market. Since the Bank is well-capitalized, the FDICIA brokered deposit rule did not adversely affect its ability to accept brokered deposits. The Bank had $1.6 billion of such brokered deposits at December 31, 2013.

As a bank holding company, we must act as a source of financial and managerial strength to the Bank and the Bank is subject to affiliate transaction restrictions.

Under the Dodd-Frank Act, a bank holding company must act as a source of financial and managerial strength to each of its subsidiary banks and must commit resources to support each such subsidiary bank. The Federal Reserve may require a bank holding company to make capital injections into a troubled subsidiary bank. It may charge the bank holding company with engaging in unsafe and unsound practices if the bank holding company fails to commit resources to such a subsidiary bank or if it undertakes actions that the Federal Reserve believes might jeopardize the bank holding company’s ability to commit resources to such subsidiary bank.

Any loans by a holding company to a subsidiary bank are subordinate in right of payment to deposits and to certain other indebtedness of such subsidiary bank. In the event of a bank holding company’s bankruptcy, an appointed bankruptcy trustee will assume any commitment by the holding company to a federal bank regulatory agency to maintain the capital of a subsidiary bank. Moreover, the bankruptcy law provides that claims based on any such commitment will be entitled to a priority of payment over the claims of the institution’s general unsecured creditors, including the holders of its note obligations.

Federal law permits the OCC to order the pro-rata assessment of shareholders of a national bank whose capital stock has become impaired, by losses or otherwise, to relieve a deficiency in such national bank’s capital stock. This statute also provides for the enforcement of any such pro-rata assessment of shareholders of such national bank to cover such impairment of capital stock by sale, to the extent necessary, of the capital stock owned by any assessed shareholder failing to pay the assessment. As the sole shareholder of the Bank, we are subject to such provisions.

Moreover, the claims of a receiver of an insured depository institution for administrative expenses and the claims of holders of deposit liabilities of such an institution are accorded priority over the claims of general unsecured creditors of such an institution, including the holders of the institution’s note obligations, in the event of liquidation or other resolution of such institution. Claims of a receiver for administrative expenses and claims of holders of deposit liabilities of the Bank, including the FDIC as the insurer of such holders, would receive priority over the holders of notes and other senior debt of the Bank in the event of liquidation or other resolution and over our interests as sole shareholder of the Bank.

As a financial holding company, we are subject to additional laws and regulations.

In order to maintain its status as a financial holding company, a bank holding company’s depository subsidiaries must all be both well-capitalized and well-managed, and must meet their Community Reinvestment Act obligations.

Financial holding company powers relate to financial activities that are specified in the Bank Holding Company Act or determined by the Federal Reserve, in coordination with the Secretary of the Treasury, to be financial in nature, incidental to an activity that is financial in nature, or complementary to a financial activity, provided that the complementary activity does not pose a safety and soundness risk. In addition, we are required by the Bank Holding Company Act to obtain Federal Reserve approval prior to acquiring, directly or indirectly, ownership or control of voting shares of any bank, if, after such acquisition, we would own or control more than 5% of its voting stock. Furthermore, the Dodd-Frank Act added a new provision to the Bank Holding Company Act, which requires bank holding companies with total consolidated assets equal to or greater than $50 billion to obtain prior approval from the Federal Reserve to acquire a nondepository company having total consolidated assets of $10 billion or more.

We also must comply with anti-money laundering and customer privacy regulations, as well as corporate governance, accounting, and reporting requirements.

The USA Patriot Act of 2001 and its related regulations require insured depository institutions, broker-dealers, and certain other financial institutions to have policies, procedures, and controls to detect, prevent, and report money laundering and terrorist financing. Federal banking regulators are required, when reviewing bank holding company acquisition and bank merger applications, to take into account the effectiveness of the anti-money laundering activities of the applicants.

Pursuant to Title V of the Gramm-Leach-Bliley Act, we, like all other financial institutions, are required to:

The Sarbanes-Oxley Act of 2002 imposed new or revised corporate governance, accounting, and reporting requirements on us. In addition to a requirement that chief executive officers and chief financial officers certify financial statements in writing, the statute imposed requirements affecting, among other matters, the composition and activities of audit committees, disclosures relating to corporate insiders and insider transactions, code of ethics, and the effectiveness of internal controls over financial reporting.

Item 1A: Risk Factors

Risk Governance

We use a multi-faceted approach to risk governance. It begins with the board of directors defining our risk appetite in aggregate as moderate-to-low. This does not preclude engagement in select higher risk activities. Rather, the definition is intended to represent an average of where we want our overall risk to be managed.

Two board committees primarily oversee implementation of this desired risk profile: The Audit Committee and the Risk Oversight Committee.

Both committees are comprised of independent directors and routinely hold executive sessions with our key officers engaged in accounting and risk management. On a periodic basis, the two committees meet in joint session to cover matters relevant to both such as the construct and appropriateness of the ACL, which is reviewed quarterly. All directors have access to information provided to each committee and all scheduled meetings are open to all directors.

Further, through its Compensation Committee, the board of directors seeks to ensure its system of rewards is risk-sensitive and aligns the interests of management, creditors, and shareholders. We utilize a variety of compensation-related tools to induce appropriate behavior, including common stock ownership thresholds for the chief executive officer and certain members of senior management, a requirement to hold until retirement a portion of net shares received upon exercise of stock options or release of restricted stock awards (50% for executive officers and 25% for other award recipients), equity deferrals, recoupment provisions, and the right to terminate compensation plans at any time.

Management has introduced a number of steps to help ensure an aggregate moderate-to-low risk appetite is maintained. Foremost is a quarterly self-assessment process, in which each business segment produces an analysis of its risks and the strength of its risk controls. The segment analyses are combined with assessments by our risk management organization of major risk sectors (e.g., credit, market, operational, reputational, compliance, etc.) to produce an overall enterprise risk assessment. Outcomes of the process include a determination of the quality of the overall control process, the direction of risk, and our position compared to the defined risk appetite.

Management also utilizes a wide series of metrics (key risk indicators) to monitor risk positions throughout the Company. In general, a range for each metric is established which allows the company, in aggregate, to maintain its moderate-to-low risk profile. Deviations from the range will indicate if the risk being measured is moving, which may then necessitate corrective action.

We also have four other executive level committees to manage risk: ALCO, Credit Policy and Strategy, Risk Management, and Capital Management. Each committee focuses on specific categories of risk and is supported by a series of subcommittees that are tactical in nature. We believe this structure helps ensure appropriate elevation of issues and overall communication of strategies.

Table of Contents

Huntington utilizes three levels of defense with regard to risk management: (1) business segments, (2) corporate risk management, and (3) internal audit and credit review. To induce greater ownership of risk within its business segments, segment risk officers have been embedded to identify and monitor risk, elevate and remediate issues, establish controls, perform self-testing, and oversee the quarterly self-assessment process. Segment risk officers report directly to the related segment manager with a dotted line to the Chief Risk Officer. Corporate Risk Management establishes policies, sets operating limits, reviews new or modified products/processes, ensures consistency and quality assurance within the segments, and produces the enterprise risk assessment. The Chief Risk Officer has significant input into the design and outcome of incentive compensation plans as they apply to risk. Internal Audit and Credit Review provide additional assurance that risk-related functions are operating as intended.

Risk Overview

We, like other financial companies, are subject to a number of risks that may adversely affect our financial condition or results of operations, many of which are outside of our direct control, though efforts are made to manage those risks while optimizing returns. Among the risks assumed are: (1) credit risk, which is the risk of loss due to loan and lease customers or other counterparties not being able to meet their financial obligations under agreed upon terms, (2) market risk, which is the risk of loss due to changes in the market value of assets and liabilities due to changes in market interest rates, foreign exchange rates, equity prices, and credit spreads, (3) liquidity risk, which is (a) the risk of loss due to the possibility that funds may not be available to satisfy current or future commitments based on external macro market issues, investor and customer perception of financial strength, and events unrelated to us such as war, terrorism, or financial institution market specific issues, and (b) the risk of loss based on our ability to satisfy current or future funding commitments due to the mix and maturity structure of our balance sheet, amount of on-hand cash and unencumbered securities and the availability of contingent sources of funding, (4) operational and legal risk, which is the risk of loss due to human error, inadequate or failed internal systems and controls, violations of, or noncompliance with, laws, rules, regulations, prescribed practices, or ethical standards, and external influences such as market conditions, fraudulent activities, disasters, and security risks, and (5) compliance risk, which exposes us to money penalties, enforcement actions or other sanctions as a result of nonconformance with laws, rules, and regulations that apply to the financial services industry.

We also expend considerable effort to contain risk which emanates from execution of our business strategies and work relentlessly to protect the Company’s reputation. Strategic risk and reputational risk do not easily lend themselves to traditional methods of measurement. Rather, we closely monitor them through processes such as new product / initiative reviews, frequent financial performance reviews, employee and client surveys, monitoring market intelligence, periodic discussions between management and our board, and other such efforts.

In addition to the other information included or incorporated by reference into this report, readers should carefully consider that the following important factors, among others, could negatively impact our business, future results of operations, and future cash flows materially.

Credit Risks:

1. Our ACL level may prove to be inappropriate or be negatively affected by credit risk exposures which could materially adversely affect our net income and capital.

Our business depends on the creditworthiness of our customers. Our ACL of $710.8 million at December 31, 2013, represented Management’s estimate of probable losses inherent in our loan and lease portfolio as well as our unfunded loan commitments and letters of credit. We periodically review our ACL for appropriateness. In doing so, we consider economic conditions and trends, collateral values, and credit quality indicators, such as past charge-off experience, levels of past due loans, and NPAs. There is no certainty that our ACL will be appropriate over time to cover losses in the portfolio because of unanticipated adverse changes in the economy, market conditions, or events adversely affecting specific customers, industries, or markets. If the credit quality of our customer base materially decreases, if the risk profile of a market, industry, or group of customers changes materially, or if the ACL is not appropriate, our net income and capital could be materially adversely affected which, in turn, could have a material adverse effect on our financial condition and results of operations.

In addition, bank regulators periodically review our ACL and may require us to increase our provision for loan and lease losses or loan charge-offs. Any increase in our ACL or loan charge-offs as required by these regulatory authorities could have a material adverse effect on our financial condition and results of operations.

2. Weakness in economic conditions could materially adversely affect our business.

Our performance could be negatively affected to the extent there is deterioration in business and economic conditions which have direct or indirect material adverse impacts on us, our customers, and our counterparties. These conditions could result in one or more of the following:

15

Table of Contents

An increase in the number of delinquencies, bankruptcies, or defaults could result in a higher level of NPAs, NCOs, provision for credit losses, and valuation adjustments on loans held for sale. The markets we serve are dependent on industrial and manufacturing businesses and thus are particularly vulnerable to adverse changes in economic conditions affecting these sectors.

Market Risks:

1. Changes in interest rates could reduce our net interest income, reduce transactional income, and negatively impact the value of our loans, securities, and other assets. This could have a material adverse impact on our cash flows, financial condition, results of operations, and capital.

Our results of operations depend substantially on net interest income, which is the difference between interest earned on interest earning assets (such as investments and loans) and interest paid on interest bearing liabilities (such as deposits and borrowings). Interest rates are highly sensitive to many factors, including governmental monetary policies and domestic and international economic and political conditions. Conditions such as inflation, deflation, recession, unemployment, money supply, and other factors beyond our control may also affect interest rates. If our interest earning assets mature or reprice faster than interest bearing liabilities in a declining interest rate environment, net interest income could be materially adversely impacted. Likewise, if interest bearing liabilities mature or reprice more quickly than interest earning assets in a rising interest rate environment, net interest income could be adversely impacted.

Changes in interest rates can affect the value of loans, securities, assets under management, and other assets, including mortgage and nonmortgage servicing rights. An increase in interest rates that adversely affects the ability of borrowers to pay the principal or interest on loans and leases may lead to an increase in NPAs and a reduction of income recognized, which could have a material adverse effect on our results of operations and cash flows. When we place a loan on nonaccrual status, we reverse any accrued but unpaid interest receivable, which decreases interest income. However, we continue to incur interest expense as a cost of funding NALs without any corresponding interest income. In addition, transactional income, including trust income, brokerage income, and gain on sales of loans can vary significantly from period-to-period based on a number of factors, including the interest rate environment.

Rising interest rates reduce the value of our fixed-rate debt securities and cash flow hedging derivatives portfolio. Any unrealized loss from these portfolios impacts OCI, shareholders’ equity, and the Tangible Common Equity ratio. Any realized loss from these portfolios impacts regulatory capital ratios, notably Tier I and Total risk-based capital ratios. In a rising interest rate environment, pension and other post-retirement obligations somewhat mitigate negative OCI impacts from securities and financial instruments.

Certain investment securities, notably mortgage-backed securities, are very sensitive to rising and falling rates. Generally, when rates rise, prepayments of principal and interest will decrease and the duration of mortgage-backed securities will increase. Conversely, when rates fall, prepayments of principal and interest will increase and the duration of mortgage-backed securities will decrease. In either case, interest rates have a significant impact on the value of mortgage-backed securities investments.

Liquidity Risks:

1. If we lose access to capital markets, we may not be able to meet the cash flow requirements of our depositors, creditors, and borrowers, or have the operating cash needed to fund corporate expansion and other corporate activities.

Liquidity is the ability to meet cash flow needs on a timely basis at a reasonable cost. The Bank uses its liquidity to extend credit and to repay liabilities as they become due or as demanded by customers. The board of directors establishes liquidity policies and limits and Management establishes operating guidelines for liquidity.

Wholesale funding sources include securitization, federal funds purchased, securities sold under repurchase agreements, non-core deposits, and medium- and long-term debt. The Bank is also a member of the Federal Home Loan Bank of Cincinnati, which provides members access to funding through advances collateralized with mortgage-related assets. We maintain a portfolio of highly-rated, marketable securities that is available as a source of liquidity.

16

Table of Contents

Capital markets disruptions can directly impact the liquidity of the Bank and Corporation. The inability to access capital markets funding sources as needed could adversely impact our financial condition, results of operations, cash flows, and level of regulatory-qualifying capital. We may, from time-to-time, consider using our existing liquidity position to opportunistically retire outstanding securities in privately negotiated or open market transactions.

2. Due to the losses that the Bank incurred in 2008 and 2009, prior to December 31, 2013, the Bank and its subsidiaries could not declare and pay dividends to the holding company, any subsidiary of the holding company outside the Bank’s consolidated group, or any security holder outside the Bank’s consolidated group, without regulatory approval. Also, the Bank may not pay a dividend in an amount greater than its undivided profits.

Dividends from the Bank to the parent company are the primary source of funds for the payment of dividends to our shareholders. Under applicable statutes and regulations, a national bank may not declare and pay dividends in any year greater than its undivided profits or in excess of an amount equal to the sum of the total of the net income of the bank for that year and the retained net income of the bank for the preceding two years, minus the sum of any transfers required by the OCC and any transfers required to be made to a fund for the retirement of any preferred stock, unless the OCC approves the declaration and payment of dividends in excess of such amount. The Bank’s undivided profits were in a deficit position until December 2013. We anticipate that the Bank will declare dividends to the holding company during the first half of 2014.

Operational and Legal Risks:

1. The resolution of significant pending litigation, if unfavorable, could have a material adverse effect on our results of operations for a particular period.

We face legal risks in our businesses, and the volume of claims and amount of damages and penalties claimed in litigation and regulatory proceedings against financial institutions remain high. Substantial legal liability against us could have material adverse financial effects or cause significant reputational harm to us, which in turn could seriously harm our business prospects. It is possible that the ultimate resolution of these matters, if unfavorable, may be material to the results of operations for a particular reporting period.

Note 22 of the Notes to Consolidated Financial Statements updates the status of litigation concerning Cyberco Holdings, Inc. Although the bank maintains litigation reserves related to this case, the ultimate resolution of the matter, if unfavorable, may be material to our results of operations for a particular reporting period.

2. We face significant operational risks which could lead to expensive litigation and loss of confidence by our customers, regulators, and capital markets.

We are exposed to many types of operational risks, including cyber-attack risk, the risk of fraud or theft by employees or outsiders, unauthorized transactions by employees or outsiders, or operational errors by employees, including clerical or record-keeping errors or those resulting from faulty or disabled computer or telecommunications systems. These operational risks could lead to expensive litigation and loss of confidence by our customers, regulators, and the capital markets.

Moreover, negative public opinion can result from our actual or alleged conduct in any number of activities, including lending practices, corporate governance, and acquisitions and from actions taken by government regulators and community organizations in response to those activities. Negative public opinion can adversely affect our ability to attract and retain customers and can also expose us to litigation and regulatory action.

Relative to acquisitions, we cannot predict if, or when, we will be able to identify and attract acquisition candidates or make acquisitions on favorable terms. We incur risks and challenges associated with the integration of acquired institutions in a timely and efficient manner, and we cannot guarantee that we will be successful in retaining existing customer relationships or achieving anticipated operating efficiencies.

Huntington is under continuous threat of loss due to cyber-attacks especially as we continue to expand customer capabilities to utilize internet and other remote channels to transact business. The most significant cyber–attack risks that we face are e-fraud, denial of service, and loss of sensitive customer data. Loss from e-fraud occurs when cybercriminals breach and extract funds directly from customer or our accounts. Loss can occur as a result of negative customer experience in the event of a successful denial of service attack that disrupts availability of our on-line banking services. The attempts to breach sensitive customer data, such as account numbers and social security numbers, could present significant reputational, legal and/or regulatory costs to us if successful. Our risk and exposure to these matters remains heightened because of the evolving nature and complexity of these threats from cybercriminals and hackers, our plans to continue to provide internet banking and mobile banking channels, and our plans to develop additional remote connectivity solutions to serve our customers.

3. Failure to maintain effective internal controls over financial reporting in the future could impair our ability to accurately and timely report our financial results or prevent fraud, resulting in loss of investor confidence and adversely affecting our business and stock price.

Effective internal controls over financial reporting are necessary to provide reliable financial reports and prevent fraud. As a financial holding company, we are subject to regulation that focuses on effective internal controls and procedures. Such controls and procedures are modified, supplemented, and changed from time-to-time as necessitated by our growth and in reaction to external events and developments. Any failure to maintain, in the future, an effective internal control environment could impact our ability to report our financial results on an accurate and timely basis, which could result in regulatory actions, loss of investor confidence, and adversely impact our business and stock price.

Compliance Risks:

1. Bank regulators and other regulations, including Basel III capital standards and CCAR, may require higher capital levels, impacting our ability to pay common stock dividends or repurchase our common stock.

On July 2, 2013, the Federal Reserve voted to adopt final Basel III capital rules for U.S. Banking organizations. The final rules establish an integrated regulatory capital framework and will implement in the United States the Basel III regulatory capital reforms from the Basel Committee on Banking Supervision and certain changes required by the Dodd-Frank Act. Under the final rule, minimum requirements will increase for both the quantity and quality of capital held by banking organizations. As a Standardized Approach institution, the Basel III minimum capital requirements will become effective for us on January 1, 2015, and will be fully phased-in on January 1, 2019.

The Federal Reserve has issued guidelines for evaluating proposals by certain bank holding companies, including us, to undertake capital actions, such as increasing dividend payments or repurchasing or redeeming stock. This process is known as CCAR. CCAR includes a quantitative examination component in which BHC-specific data is run through models developed by the Federal Reserve with the intention of estimating capital levels in a hypothetical severely adverse economic scenario. Capital plans for 2014 were required to be submitted by January 6, 2014. The Federal Reserve will either object to a capital plan, in whole or in part, or provide a notice of non-objection no later than March 31, 2014, for plans submitted by the January 6, 2014 submission date. We submitted our capital plan to the Federal Reserve on January 5, 2014.

The Federal Reserve and OCC are expected to undertake these capital plan reviews on a regular basis in the future. There can be no assurance that the Federal Reserve or OCC will respond favorably to our capital plan as part of their future capital plan reviews, and the Federal Reserve, OCC, or other regulatory capital requirements may limit or otherwise restrict how we utilize our capital, including common stock dividends and stock repurchases. Although not currently anticipated, our regulators may require us to raise additional capital in the future. Issuing additional common stock may dilute existing stockholders.

2. If our regulators deem it appropriate, they can take regulatory actions that could result in a material adverse impact on our ability to compete for new business, constrain our ability to fund our liquidity needs or pay dividends, and increase the cost of our services.

We are subject to the supervision and regulation of various state and Federal regulators, including the OCC, Federal Reserve, FDIC, SEC, CFPB, Financial Industry Regulatory Authority, and various state regulatory agencies. As such, we are subject to a wide variety of laws and regulations, many of which are discussed in the Regulatory Matters section. As part of their supervisory process, which includes periodic examinations and continuous monitoring, the regulators have the authority to impose restrictions or conditions on our activities and the manner in which we manage the organization. Such actions could negatively impact us in a variety of ways, including monetary fines, impacting our ability to pay dividends, precluding mergers or acquisitions, limiting our ability to offer certain products or services, or imposing additional capital requirements.

With the development of the CFPB, our consumer products and services are subject to increasing regulatory oversight and scrutiny with respect to compliance under consumer laws and regulations. We may face a greater number or wider scope of investigations, enforcement actions and litigation in the future related to consumer practices, thereby increasing costs associated with responding to or defending such actions. In addition, increased regulatory inquiries and investigations, as well as any additional legislative or regulatory developments affecting our consumer businesses, and any required changes to our business operations resulting from these developments, could result in significant loss of revenue, limit the products or services we offer, require us to increase our prices and therefore reduce demand for our products, impose additional compliance costs on us, cause harm to our reputation or otherwise adversely affect our consumer businesses.

18

Table of Contents

3. Legislative and regulatory actions taken now or in the future that impact the financial industry may materially adversely affect us by increasing our costs, adding complexity in doing business, impeding the efficiency of our internal business processes, negatively impacting the recoverability of certain of our recorded assets, requiring us to increase our regulatory capital, limiting our ability to pursue business opportunities, and otherwise result in a material adverse impact on our financial condition, results of operation, liquidity, or stock price.

The Dodd-Frank Act represents a comprehensive overhaul of the financial services industry within the United States, establishes the CFPB, and requires the bureau and other federal agencies to implement many new and significant rules and regulations. At this time, it is difficult to predict the extent to which the Dodd-Frank Act, or the resulting rules and regulations in their entirety, will impact our business. Compliance with these new laws and regulations will result in additional costs, which could be significant, and may have a material and adverse effect on our results of operations. In addition, if we do not appropriately comply with current or future legislation and regulations that apply to our consumer operations, we may be subject to fines, penalties or judgments, or material regulatory restrictions on our businesses, which could adversely affect operations and, in turn, financial results.

Item 7: Management’s Discussion and Analysis of Financial Condition and Results of Operations

INTRODUCTION

We are a multi-state diversified regional bank holding company organized under Maryland law in 1966 and headquartered in Columbus, Ohio. Through the Bank, we have 148 years of servicing the financial needs of our customers. Through our subsidiaries, we provide full-service commercial and consumer banking services, mortgage banking services, automobile financing, equipment leasing, investment management, trust services, brokerage services, insurance service programs, and other financial products and services. Our 695 branches are located in Ohio, Michigan, Pennsylvania, Indiana, West Virginia, and Kentucky. Selected financial services and other activities are also conducted in various other states. International banking services are available through the headquarters office in Columbus, Ohio and a limited purpose office located in the Cayman Islands and another limited purpose office located in Hong Kong. Our foreign banking activities, in total or with any individual country, are not significant.

The following MD&A provides information we believe necessary for understanding our financial condition, changes in financial condition, results of operations, and cash flows. The MD&A should be read in conjunction with the Consolidated Financial Statements, Notes to Consolidated Financial Statements, and other information contained in this report.

Our discussion is divided into key segments:

EXECUTIVE OVERVIEW

2013 Financial Performance Review

In 2013, we reported net income of $638.7 million, or $0.72 per common share, relatively unchanged from the prior year. This resulted in a 1.13% return on average assets and a 12.7% return on average tangible common equity. In addition, we grew our base of consumer and business customers while our efficiency ratio decreased to 62.9% in 2013 from 63.4% in 2012. Results from our strategic business investments and OCR sales approach continued in 2013. (Also, see Significant Items Influencing Financial Performance Comparisons within the Discussion of Results of Operations.)

Fully-taxable equivalent net interest income was $1.7 billion in 2013, an increase of $1.0 million, or less than 1%, compared with 2012. This reflected the impact of 4% loan growth, offset by a 5 basis point decline in the net interest margin to 3.36%, as well as a 7% reduction in other earning assets, the majority of which were loans held for sale. The loan growth reflected an increase in average C&I loans due to continued growth within the middle market healthcare vertical, equipment finance, and dealer floorplan loans. Also, our average automobile loans increased, as the growth in originations remained strong and we kept these loans on our balance sheet instead of selling them through securitizations. As expected, our CRE portfolio declined, reflecting continued runoff as acceptable returns for new originations were balanced against internal concentration limits and increased competition for projects sponsored by high quality developers. Average loans held-for-sale decreased, reflecting the impact of automobile securitizations completed in 2012 and no such securitizations in 2013.

24

Table of Contents

Noninterest income was $1.0 billion in 2013, a 9% decrease compared with 2012. Mortgage banking income was down $64.2 million due to a reduction in volume, lower gain on sale margin, and a higher percentage of originations held on the balance sheet. In addition, gains on sale of loans were down $40.0 million due to no auto securitizations in 2013. Service charges increased $9.6 million in 2013 despite a decrease of approximately $28 million due to a change that we made in February 2013 on posting order for our consumer transaction accounts.

Noninterest expense was $1.8 billion in 2013, a 4% decrease compared with 2012. The decrease was primarily due to lower marketing, deposit and other insurance, professional services and other expense as we actively managed the pace and size of investment. Other expense declined due to lower mortgage repurchase and warranty, and OREO and foreclosure expenses. This was partially offset by franchise repositioning expense related significant items included in net occupancy ($12.1 million), personnel costs ($6.7 million), equipment ($2.4 million), outside data processing and other services ($1.4 million), and other expense ($1.0 million). The increase in personnel costs primarily related to the increase in the number of average full-time equivalent employees was partially offset by a significant item of $33.9 million from the pension curtailment gain.

Most credit quality related metrics in 2013 reflected continued improvement. NALs declined $85.6 million, or 21%, from 2012 to $322.1 million, or 0.75% of total loans and leases. NPAs declined $93.6 million, or 21%, compared to a year-ago to $352.2 million, or 0.82% of total loans and leases, OREO, and other NPAs. The decreases primarily reflected meaningful improvement in both CRE and C&I NALs. The provision for credit losses decreased $57.3 million, or 39%, from 2012 due to the continued decline in classified, criticized, and nonaccrual loans and included the implementation of enhancements to our ALLL model. NCOs decreased $153.8 million, or 45%, from the prior year to $188.7 million. NCOs were an annualized 0.45% of average loans and leases in the current year compared to 0.85% in 2012. Within the consumer portfolio, NCOs related to Chapter 7 bankruptcy loans amounted to $22.8 million in 2013 and $34.6 million in 2012. The ACL as a percentage of total loans and leases decreased to 1.65% from 1.99% a year ago, while the ACL as a percentage of period-end total NALs increased to 221% from 199%.

The tangible common equity to tangible assets ratio at December 31, 2013, was 8.83%, up 7 basis points from a year ago. Our Tier 1 common risk-based capital ratio at year end was 10.90%, up from 10.48% at the end of 2012. The regulatory Tier 1 risk-based capital ratio at December 31, 2013, was 12.28%, up from 12.02% at December 31, 2012. The increase in the regulatory Tier 1 risk-based capital ratio reflected the increase in retained earnings, partially offset by the redemption of $50 million of qualifying REIT preferred securities in the 2013 fourth quarter, and growth in risk-weighted assets. All capital ratios were impacted by the repurchase of 17 million common shares over the last four quarters, none of which were repurchased during the 2013 fourth quarter. We have the ability to repurchase up to $136 million additional shares of common stock through the first quarter of 2014. We intend to continue disciplined repurchase activity consistent with our annual capital plan, our capital return objectives, and market conditions.

Business Overview

General

Our general business objectives are: (1) grow net interest income and fee income, (2) increase cross-sell and share-of-wallet across all business segments, (3) improve efficiency ratio, (4) continue to strengthen risk management, including sustained improvements in credit metrics, and (5) maintain strong capital and liquidity positions.

In 2013, we grew our base of consumer and business customers, while achieving positive operating leverage. Our performance in the second half of 2013 demonstrates strong business momentum, positioning us well for 2014. Highlights of our financial strength in 2013 include a strong balance sheet, ongoing deposit growth and quality loan growth in commercial and auto lending. Our deposit and lending growth is the result of focused execution and key strategic investments made over the last four years. We have done all of this while decreasing expenses by 4 percent, year over year, as the result of disciplined expense management.

We continue to face strong competition from other banks and financial service firms in our markets. To address these challenges, the cornerstone of our strategy has been to invest in the franchise in order to grow our market share and share-of-wallet. In this regard, our OCR methodology continued to deliver success in 2013. Consumer checking account households grew by 96 thousand households, or 8%, over the last year. Commercial relationships grew at a rate of 6% and have increased by 9 thousand commercial customers since 2012. Our “Fair Play” philosophy, combined with continued OCR success, positively impacted results in 2013.

Economy

The environment in 2013 was different than we thought it would be when we started the year, as the economic, interest rate, and political environments were more challenging. Currently, we are seeing good momentum going into 2014, as customers seem to have a slightly better mindset as the political environment seems to be less of an issue and the general economic outlook is more positive as evidenced by the following:

2014 Expectations

Net interest income is expected to moderately increase. We anticipate an increase in earning assets as total loans moderately grow and investment securities remain near current levels. However, those benefits to net interest income are expected to be mostly offset by continued downward pressure on NIM. While we are maintaining a disciplined approach to loan pricing, asset yields remain under pressure but the continued opportunity of deposit repricing remains, albeit closer to current levels.

The C&I portfolio is expected to grow consistent with the anticipated increase in customer activity. Our C&I loan pipeline remains robust with much of this reflecting the positive impact from our investments in specialized commercial verticals, automotive dealer relationships, focused OCR sales process, and continued support of middle market and small business lending. Automobile loan originations remain strong, and we currently do not anticipate any automobile securitizations in the near future. Residential mortgages, home equity, and CRE loan balances are expected to increase modestly.

We anticipate the increase in total loans will modestly outpace growth in total deposits. This reflects our continued focus on the overall cost of funds, through the issuance of long-term debt, as well as the continued shift towards low- and no-cost demand deposits and money market deposit accounts.

Noninterest income, excluding the impact of any net MSR activity, is expected to be slightly lower than recent levels, due to the anticipated decline in mortgage banking revenues and the continued refinement of products under our Fair Play philosophy.

Noninterest expense, excluding the net $10 million of benefit from Significant Items we experienced in 2013, is expected to remain around current levels. We are committed to delivering positive operating leverage for the 2014 full year.

NPAs are expected to show continued improvement. This year, NCOs represented the mid-point of our expected normalized range of 35 to 55 basis points. The level of provision for credit losses was below our long-term expectation, and we continue to expect moderate quarterly volatility.

The effective tax rate for 2014 is expected to be in the range of 25% to 28%, primarily reflecting the impacts of tax-exempt income, tax-advantaged investments, and general business credits.
