Some of the information in this report contains “forward-looking statements” within the meaning of and are intended to be covered by the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements typically are identified with use of terms such as “may,” “might,” “will,” “should,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “potential,” “could,” “continue” and the negative of these terms and similar words, although some forward-looking statements are expressed differently. Our ability to predict results or the actual effect of future plans or strategies is inherently uncertain. You should be aware that our actual results could differ materially from those contained in the forward-looking statements due to a number of factors, including, but not limited to: credit risk; changes in the appraised valuation of real estate securing impaired loans; outcomes of litigation and other contingencies; exposure to general and local economic conditions; risks associated with rapid increases or decreases in prevailing interest rates; consolidation within the banking industry; competition from banks and other financial institutions; our ability to attract and retain relationship officers and other key personnel; burdens imposed by federal and state regulation; changes in regulatory requirements; changes in accounting regulation or standards applicable to banks; and other risks discussed under Part I-Item 1A: “Risk Factors,” all of which could cause the Company's actual results to differ from those set forth in the forward-looking statements.

Readers are cautioned not to place undue reliance on our forward-looking statements, which reflect management's analysis and expectations only as of the date of such statements. Forward-looking statements speak only as of the date they are made, and the Company does not intend, and undertakes no obligation, to publicly revise or update forward-looking statements after the date of this report, whether as a result of new information, future events or otherwise, except as required by federal securities law.

PART 1

ITEM 1: BUSINESS

General

Enterprise Financial Services Corp (“we” or the “Company” or “Enterprise”), a Delaware corporation, is a financial holding company headquartered in St. Louis, Missouri. We are the holding company for a full service banking subsidiary, Enterprise Bank & Trust (the “Bank”), offering banking and wealth management services to individuals and business customers located in the St. Louis, Kansas City and Phoenix metropolitan markets. Our executive offices are located at 150 North Meramec, Clayton, Missouri 63105 and our telephone number is (314) 725-5500.

Available Information

Our website is www.enterprisebank.com. Various reports provided to the SEC, including our annual reports, quarterly reports, current reports and proxy statements are available free of charge on our website. These reports are made available as soon as reasonably practicable after they are electronically filed with or furnished to the SEC. Our filings with the SEC are also available on the SEC's website at http://www.sec.gov.

Business Strategy

Our stated mission is “to guide our clients to a lifetime of financial success.” We have established an accompanying corporate vision “to build an exceptional company that clients value, shareholders prize and where our associates flourish.” These tenets are fundamental to our business strategies and operations.

Our general business strategy is to generate superior shareholder returns by providing comprehensive financial services primarily to private businesses, their owner families, and other success-minded individuals through banking and wealth management lines of business. Each of which constitutes a separate segment for purposes of our financial reporting.

Our banking segment offers a broad range of business and personal banking services. Lending services include commercial and industrial, commercial real estate, real estate construction and development, residential real estate, and consumer loans. A wide variety of deposit products and a complete suite of treasury management and international trade services complement our lending capabilities.

1

The wealth management segment includes the Company's trust operations and Federal and Missouri State tax credit brokerage activities. Enterprise Trust, a division of the Bank (“Enterprise Trust” or “Trust”) provides financial planning, estate planning, investment management and trust services to businesses, individuals, institutions, retirement plans and non-profit organizations. Tax credit brokerage activities consist of the acquisition of tax credits and sale of these tax credits to clients. See Item 8. Note 21 - Segment Reporting for more information about our segments.

Key components of our strategy include a focused and relationship-oriented distribution and sales approach, with an emphasis on growing fee income and niche businesses, prudent credit and interest rate risk management, advanced technology and controlled expense growth.

Building long-term client relationships - Our growth strategy is largely client relationship driven. We continuously seek to add clients who fit our target market of business owners, professionals, and associated relationships. Those relationships are maintained, cultivated and expanded over time by trained, experienced banking officers and wealth advisors. We fund loan growth primarily with core deposits from our business and professional clients in addition to consumers in our branch market areas. This is supplemented by borrowing from the Federal Home Loan Bank of Des Moines (the “FHLB”), the Federal Reserve, and by issuing brokered certificates of deposits.

Growing fee income business - Enterprise Trust offers a wide range of fiduciary, investment management and financial advisory services. We employ attorneys, certified financial planners, estate planning professionals and other investment professionals. Enterprise Trust representatives assist clients in defining lifetime goals and designing plans to achieve them, consistent with the Company's long-term relationship strategy. The Bank offers a broad range of Treasury Management products and services that benefit businesses ranging from large national clients to the smallest local merchants. Customized solutions and special product bundles are available to clients of all sizes.  Responding to ever increasing needs for tightened security and improved functional efficiency, the Bank continues to offer robust treasury systems that employ the latest in mobile technology and fraud detection/mitigation. The Bank also operates treasury management, card services and international banking divisions that generate fee income.

Specialty Lending and Product Niches - We have focused an increasing amount of our lending activities in specialty markets where we believe our expertise and experience as a sophisticated commercial lender provides advantages over other competitors. In addition, we have developed expertise in certain product niches. These specialty niche activities focus on the following areas:

• Enterprise Value Lending/Senior Debt Financing. We support mid-market company mergers and acquisitions primarily for Midwest-based manufacturing companies. We market directly to targeted private equity firms and provide a combination of senior debt and mezzanine debt financing.

• Tax Credit Related Lending. We are a secured lender on affordable housing projects funded through the use of Federal and Missouri State Low Income housing tax credits. The Company also brokers State Low Income credits from its inventory to its clients. In addition, we provide leveraged and other loans on projects funded through the Department of the Treasury CDFI New Markets Tax Credit program. In 2011 and 2013, we were selected as one of the relatively few banks for New Markets Tax Credits. In this capacity, we were responsible for allocating $75 million of New Markets Tax Credits to clients and projects.

• Tax Credit Brokerage. We acquire Missouri state tax credits from affordable housing development funds and sells the tax credits to clients and other individuals for tax planning purposes.

• Life Insurance Premium Finance. We specialize in financing high-end whole life insurance premiums utilized in high net worth estate planning.

• Enterprise Advisory Services. We have developed a proprietary deposit platform allowing registered investment advisory firms to offer FDIC insured cash deposits in addition to other investment products.

Capitalizing on technology - We view our technological capabilities to be a competitive advantage. Our systems provide Internet banking, expanded treasury management products, check and document imaging and remote deposit capture systems. Other services currently offered by the Bank include controlled disbursements, repurchase agreements and sweep investment accounts. Our treasury management suite of products blends advanced technology and personal

2

service, often creating a competitive advantage over larger, nationwide banks. Technology is also extensively utilized in internal systems, operational support functions to improve customer service, and management reporting and analysis.

Maintaining asset quality - The Company monitors asset quality through formal ongoing, multiple-level reviews of loans in each market. These reviews are overseen by the Company's credit administration department. In addition, the Bank's loan portfolio is subject to ongoing monitoring by a loan review function that reports directly to the audit committee of our board of directors.

Expense management - The Company manages expenses carefully through detailed budgeting and expense approval processes. We measure the “efficiency ratio” as a benchmark for improvement. The efficiency ratio is equal to noninterest expense divided by total revenue (net interest income plus noninterest income). Continued improvement is targeted to increase earnings per share and generate higher returns on equity.

Acquisitions and Divestitures

Since December 2009, the Bank has entered into four agreements with the Federal Deposit Insurance Corporation (“FDIC”) to acquire certain assets and assume certain liabilities of four failed banks: Valley Capital Bank, Home National Bank, Legacy Bank and The First National Bank of Olathe. In conjunction with each of these, the Bank entered into loss share agreements, under which the FDIC has agreed to reimburse the Bank for a percentage of losses on certain loans and other real estate acquired (“Covered Assets”). The reimbursable losses from the FDIC are based on the book value of the acquired loans and foreclosed assets as determined by the FDIC as of the date of each acquisition.

• Valley Capital Bank (“Valley Capital”) - On December 11, 2009, the Bank acquired certain assets and assumed certain liabilities of Valley Capital, a full service community bank that was headquartered in Mesa, Arizona. 

• Home National Bank (“Home National”) - On July 9, 2010, the Bank acquired approximately $256.0 million in Arizona-originated assets from the FDIC in connection with the failure of Home National, an Oklahoma bank with operations in Arizona.

• Legacy Bank (“Legacy”) - On January 7, 2011, the Bank acquired certain assets and assumed certain liabilities of Legacy, a full service community bank that was headquartered in Scottsdale, Arizona. 

• The First National Bank of Olathe (“FNBO") - On August 12, 2011, the Bank acquired certain assets and assumed certain liabilities of FNBO, a full service community bank that was headquartered in Olathe, Kansas. 

On October 21, 2011, the Bank purchased certain assets and assumed certain deposit liabilities from BankLiberty of Liberty, Missouri. The Bank assumed $43.0 million in deposits associated with the BankLiberty branch located at 11401 Olive Boulevard, in the St. Louis suburb of Creve Coeur, Missouri. The deposits consisted of $2.6 million in demand deposits, $21.9 million in money market and other interest bearing deposits, and $18.5 million in certificates of deposit. The Bank also paid a deposit premium of $323,000 on these deposits and purchased $150,000 of personal property in the branch. The Bank executed a sublease on approximately 6,556 square feet at the above address. Enterprise currently operates the location as a full-service branch of the Bank.

On May 16, 2013, the Company finalized its acquisition of certain assets of Gorman & Gorman Home Loans. In addition, Mark Gorman, founder and president of Gorman & Gorman, and the firm's mortgage production and operations staff joined the Company. The Gorman & Gorman and legacy Enterprise mortgage operations were combined into a division of the Bank named Enterprise Home Loans. The Company anticipates that the acquisition will strengthen its mortgage business.

On December 6, 2013, the Bank completed the sale and closure of 4 of its branches in the Kansas City market. The sale agreement called for 2 branches to be sold to another financial institution as well as $7.6 million of loans, $78.4 million of deposits, and $1.5 million of other assets. The sale resulted in a pre-tax gain of approximately $1.0 million primarily due to a premium received on the deposits sold as part of the transaction.

TARP Repayment and Common Stock Warrant Repurchase

On November 7, 2012, the Company repurchased from the United States Department of the Treasury (the “Treasury”) all 35,000 outstanding shares of its Fixed Rate Cumulative Perpetual Preferred Stock, Series A (the “Series A Preferred”) pursuant to a letter agreement with the Treasury of that date (the “Repurchase Agreement”). The Company paid an aggregate purchase price of approximately $35.4 million to the Treasury, which included a $1,000 per share liquidation amount and approximately $399,000for accrued and unpaid dividends. The Company originally sold the Series A Preferred to the Treasury on December 19, 2008 pursuant to the Treasury's Capital Purchase Program.

On January 9, 2013, the Company repurchased the warrants issued to the U.S. Treasury as part of the Capital Purchase Program. The warrants provided the right to purchase 324,074 shares of the Company's common stock. Enterprise and the Treasury department agreed upon a repurchase price of approximately $1.0 million for the warrants. This transaction completed the Company's participation in the Treasury's Capital Purchase Program.

Debt Repayments

During 2013 the Company completed two transactions that significantly reduced its long term debt. On August 15, 2013, the Company converted $20.0 million, 9% coupon, trust preferred securities to shares of common stock. As a result of the transaction, the Company reduced its long-term debt by $20.0 million and issued an aggregate of 1.2 million shares of common stock. The Company issued 25,060 shares of additional common stock as an inducement for the conversion. On December 30, 2013, the Company prepaid $30.0 million of debt with the Federal Home Loan Bank ("FHLB") with a weighted average interest rate of 4.09% and a maturity of 3 years and incurred a prepayment penalty of $2.6 million before taxes. These transactions are expected to further reduce our cost of interest bearing liabilities in future periods and continue to manage interest rate risk.

Market Areas and Approach to Geographic Expansion

We operate in the St. Louis, Kansas City and Phoenix metropolitan areas. The Company, as part of its expansion effort, plans to continue its strategy of operating branches with larger average deposits, and employing experienced staff who are compensated on the basis of performance and customer service.

St. Louis - We have six banking facilities in the St. Louis metropolitan area. The St. Louis market enjoys a stable, diverse economic base and is ranked the 19^th largest metropolitan statistical area in the United States. It is an attractive market for us with nearly 70,000 privately held businesses and more than 50,000 households with investable assets of $1.0 million or more.

Kansas City - We have eight banking facilities in the Kansas City market. Kansas City is also an attractive private company market with over 50,000 privately held businesses and more than 40,000 households with investable assets of $1.0 million or more. It is the 31^st largest metropolitan area in the U.S.

Phoenix - Since December 2009, we have completed four FDIC-assisted transactions in the Phoenix market. We have two banking facilities in the Phoenix metropolitan area.

We believe the Phoenix market offers long-term growth opportunities for the Company. The underlying demographic and geographic factors that propelled Phoenix into one of the fastest growing and most dynamic markets in the country should drive continued growth in that market. Today, Phoenix is the nation's 13^th largest metropolitan area, and has more than 90,000 privately held businesses and more than 80,000 households with investable assets over $1.0 million.

Competition

The Company and its subsidiaries operate in highly competitive markets. Our geographic markets are served by a number of large multi-bank holding companies with substantial capital resources and lending capacity. Many of the larger banks have established specialized units, which target private businesses and high net worth individuals. Also, the St. Louis, Kansas City and Phoenix markets have numerous small community banks. In addition to other financial holding companies and commercial banks, we compete with credit unions, thrifts, investment managers, brokerage firms, and other providers of financial services and products.

Supervision and Regulation

The following is a summary description of the relevant laws, rules, and regulations governing banks and financial holding companies. The description of, and references to, the statutes and regulations below are brief summaries and do not purport to be complete. The descriptions are qualified in their entirety by reference to the specific statutes and regulations discussed.

The regulatory and supervisory structure establishes a comprehensive framework of activities in which an institution can engage and is intended primarily for the protection of depositors, the deposit insurance funds and the banking system as a whole, rather than for the protection of shareholders or creditors. The regulatory structure also gives the regulatory authorities extensive discretion in connection with their supervisory and enforcement activities and examination policies, including policies concerning the establishment of deposit insurance assessment fees, classification of assets and establishment of adequate loan loss reserves for regulatory purposes.

Various legislation is from time to time introduced in Congress and Missouri's legislature, including proposals to overhaul the bank regulatory system, expand the powers of depository institutions, and limit the investments that depository institutions may make with insured funds. Such legislation may change applicable statutes and the operating environment in substantial and unpredictable ways. We cannot determine the ultimate effect that future legislation or implementing regulations would have upon our financial condition or upon our results of operations or the results of operations of any of our subsidiaries. As is further described below, the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank Act”), has significantly changed the bank regulatory structure and may affect the lending, investment and general operating activities of depository institutions and their holding companies

Financial Holding Company

The Company is a financial holding company registered under the Bank Holding Company Act of 1956, as amended (“BHCA”). As a financial holding company, the Company is subject to regulation and examination by the Federal Reserve, and is required to file periodic reports of its operations and such additional information as the Federal Reserve may require. In order to remain a financial holding company, the Company must continue to be considered well managed and well capitalized by the Federal Reserve and have at least a “satisfactory” rating under the Community Reinvestment Act. See “Liquidity and Capital Resources” in the Management Discussion and Analysis for more information on our capital adequacy and “Bank Subsidiary - Community Reinvestment Act” below for more information on the Community Reinvestment Act.

Acquisitions: With certain limited exceptions, the BHCA requires every financial holding company or bank holding company to obtain the prior approval of the Federal Reserve before (i) acquiring substantially all the assets of any bank, (ii) acquiring direct or indirect ownership or control of any voting shares of any bank if, after such acquisition, it would own or control more than 5% of the voting shares of such bank (unless it already owns or controls the majority of such shares), or (iii) merging or consolidating with another bank holding company. Additionally, the BHCA provides that the Federal Reserve may not approve any of these transactions if it would result in or tend to create a monopoly, substantially lessen competition, or otherwise function as a restraint of trade, unless the anti-competitive effects of the proposed transaction are clearly outweighed by the public interest in meeting the convenience and needs of the community to be served. The Federal Reserve is also required to consider the financial and managerial resources and future prospects of the bank holding companies and banks concerned and the convenience and needs of the community to be served. The Federal Reserve’s consideration of financial resources generally focuses on capital adequacy, which is discussed below.

Change in Bank Control: Subject to various exceptions, the BHCA and the Change in Bank Control Act, together with related regulations, require Federal Reserve approval prior to any person or company acquiring “control” of a bank or financial holding company. Control is conclusively presumed to exist if an individual or company acquires 25% or more of any class of voting securities of the Company. Control is rebuttably presumed to exist if a person or company acquires 10% or more, but less than 25%, of any class of voting securities of the Company. The regulations provide a procedure for challenging rebuttable presumptions of control.

5

Permitted Activities: The BHCA has generally prohibited a bank holding company from engaging in activities other than banking or managing or controlling banks or other permissible subsidiaries and from acquiring or retaining direct or indirect control of any company engaged in any activities other than those determined by the Federal Reserve to be closely related to banking or managing or controlling banks as to be a proper incident thereto. Provisions of the Gramm-Leach-Bliley Act have expanded the permissible activities of a bank holding company that qualifies as a financial holding company. Under the regulations implementing the Gramm-Leach-Bliley Act, a financial holding company may engage in additional activities that are financial in nature or incidental or complementary to financial activities. Those activities include, among other activities, certain insurance, advisory and securities activities.

Support of Bank Subsidiaries: Under Federal Reserve policy, the Company is expected to act as a source of financial strength for the Bank and to commit resources to support the Bank. In addition, pursuant to the Dodd-Frank Act, this longstanding policy has been given the force of law and additional regulations promulgated by the Federal Reserve to further implement the intent of the new statute are possible. As in the past, such financial support from the Company may be required at times when, without this legal requirement, the Company may not be inclined to provide it.

Capital Adequacy: The Company is also subject to capital requirements applied on a consolidated basis, which are substantially similar to those required of the Bank (summarized below).

Dividend Restrictions: Under Federal Reserve policies, financial holding companies may pay cash dividends on common stock only out of income available over the past year if prospective earnings retention is consistent with the organization's expected future needs and financial condition and if the organization is not in danger of not meeting its minimum regulatory capital requirements. Federal Reserve policy also provides that financial holding companies should not maintain a level of cash dividends that undermines the financial holding company's ability to serve as a source of strength to its banking subsidiaries.

Bank Subsidiary

At December 31, 2013, Enterprise Bank & Trust was our only bank subsidiary. The Bank is a Missouri trust company with banking powers and is subject to supervision and regulation by the Missouri Division of Finance. In addition, as a Federal Reserve non-member bank, it is subject to supervision and regulation by the FDIC. The Bank is a member of the FHLB of Des Moines.

The Bank is subject to extensive federal and state regulatory oversight. The various regulatory authorities regulate or monitor all areas of the banking operations, including security devices and procedures, adequacy of capitalization and loss reserves, loans, investments, borrowings, deposits, mergers, issuance of securities, payment of dividends, interest rates payable on deposits, interest rates or fees chargeable on loans, establishment of branches, corporate reorganizations, maintenance of books and records, and adequacy of staff training to carry on safe lending and deposit gathering practices. The Bank must maintain certain capital ratios and is subject to limitations on aggregate investments in real estate, bank premises, low income housing projects, and furniture and fixtures. In connection with their supervision and regulation responsibilities, the Bank is subject to periodic examination by the FDIC and Missouri Division of Finance.

Capital Adequacy: The Bank is required to comply with the FDIC’s capital adequacy standards for insured banks. The FDIC has issued risk-based capital and leverage capital guidelines for measuring capital adequacy, and all applicable capital standards must be satisfied for the Bank to be considered in compliance with regulatory capital requirements.

Under the regulatory capital requirements, at least half of the Bank’s total capital must be composed of “Tier 1 Capital.” Tier 1 Capital includes common equity, undivided profits, minority interests in the equity accounts of consolidated subsidiaries, qualifying noncumulative perpetual preferred stock, and a limited amount of cumulative perpetual preferred stock, less goodwill and various other intangible assets.

The Bank’s capital categories are determined for the purpose of applying the “prompt corrective action” rules described below and may be taken into consideration by banking regulators in evaluating proposals for expansion or new activities.

6

They are not necessarily an accurate representation of a bank's overall financial condition or prospects for other purposes. A failure to meet the capital guidelines could subject the Bank to a variety of enforcement actions under those rules, including the issuance of a capital directive, the termination of deposit insurance by the FDIC, a prohibition on the taking of brokered deposits, and other restrictions on its business. As described below, the FDIC also can impose other substantial restrictions on banks that fail to meet applicable capital requirements.

Federal law establishes a system of prompt corrective action to resolve the problems of undercapitalized banks. Under this system, the FDIC has established five capital categories (“well capitalized,” “adequately capitalized,” “undercapitalized,” “significantly undercapitalized,” and “critically undercapitalized”) and is required to take various mandatory supervisory actions, and is authorized to take other discretionary actions with respect to banks in the three undercapitalized categories. The severity of any such actions taken will depend upon the capital category in which a bank is placed. Generally, subject to a narrow exception, current federal law requires the FDIC to appoint a receiver or conservator for a bank that is critically undercapitalized.

Under the FDIC’s prompt corrective action rules, a bank that (1) has a total capital to risk-weighted assets ratio (the “Total Capital Ratio”) of 10.0% or greater, a Tier 1 Capital to risk-weighted assets ratio (the “Tier 1 Capital Ratio”) of 6.0% or greater, and a Tier 1 Capital to average assets (the “Leverage Ratio”) of 5.0% or greater, and (2) is not subject to any written agreement, order, capital directive, or prompt corrective action directive issued by the FDIC, is considered to be “well capitalized.” A bank with a Total Capital Ratio of 8.0% or greater, a Tier 1 Capital Ratio of 4.0% or greater, and a Leverage Ratio of 4.0% or greater, is considered to be “adequately capitalized.” A bank that has a Total Capital Ratio of less than 8.0%, a Tier 1 Capital Ratio of less than 4.0%, or a Leverage Ratio of less than 4.0%, is considered to be “undercapitalized.” A bank that has a Total Capital Ratio of less than 6.0%, a Tier 1 Capital Ratio of less than 3.0%, or a Leverage Ratio of less than 3.0%, is considered to be “significantly undercapitalized,” and a bank that has a tangible equity capital to assets ratio equal to or less than 2.0% is deemed to be “critically undercapitalized.” A bank may be considered to be in a capitalization category lower than indicated by its actual capital position if it receives an unsatisfactory examination rating or is subject to a regulatory action that requires heightened levels of capital.

A bank that becomes “undercapitalized,” “significantly undercapitalized,” or “critically undercapitalized” is required to submit an acceptable capital restoration plan to the FDIC. An “undercapitalized” bank also is generally prohibited from increasing its average total assets, making acquisitions, establishing new branches, or engaging in any new line of business, except in accordance with an accepted capital restoration plan or with the approval of the FDIC. Also, the FDIC may treat an “undercapitalized” bank as being “significantly undercapitalized” if it determines that those actions are necessary to carry out the purpose of the law.

At December 31, 2013, all of the Bank’s capital ratios were at levels that would qualify it to be “well capitalized” for regulatory purposes.

Dividends by the Bank Subsidiary: Under Missouri law, the Bank may pay dividends to the Company only from a portion of its undivided profits and may not pay dividends if its capital is impaired. As an insured depository institution, federal law prohibits the Bank from making any capital distributions, including the payment of a cash dividend if it is “undercapitalized” or after making the distribution would become undercapitalized. If the FDIC believes that the Bank is engaged in, or about to engage in, an unsafe or unsound practice, the FDIC may require, after notice and hearing, that the bank cease and desist from that practice. The FDIC has indicated that paying dividends that deplete a depository institution’s capital base to an inadequate level would be an unsafe and unsound banking practice. The FDIC has issued policy statements that provide that insured banks generally should pay dividends only from their current operating earnings. The Bank’s payment of dividends also could be affected or limited by other factors, such as events or circumstances which lead the FDIC to require that it maintain capital in excess of regulatory guidelines.

Transactions with Affiliates and Insiders: The Bank is subject to the provisions of Regulation W promulgated by the Federal Reserve, which encompasses Sections 23A and 23B of the Federal Reserve Act. Regulation W places limits and conditions on the amount of loans or extensions of credit to, investments in, or certain other transactions with, affiliates and on the amount of advances to third parties collateralized by the securities or obligations of affiliates. Regulation W also prohibits, among other things, an institution from engaging in certain transactions with certain

7

affiliates unless the transactions are on terms substantially the same, or at least as favorable to such institution or its subsidiaries, as those prevailing at the time for comparable transactions with nonaffiliated companies. Federal law also places restrictions on the Bank’s ability to extend credit to its executive officers, directors, principal shareholders and their related interests. These extensions of credit must be made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with unrelated third parties; and must not involve more than the normal risk of repayment or present other unfavorable features.

Customer Protection: The Bank is also subject to consumer laws and regulations intended to protect consumers in transactions with depository institutions, as well as other laws or regulations affecting customers of financial institutions generally. While the list set forth herein is not exhaustive, these laws and regulations include the Truth in Lending Act, the Truth in Savings Act, the Electronic Funds Transfer Act, the Expedited Funds Availability Act, the Equal Credit Opportunity Act, the Fair Housing Act, the Real Estate Settlement and Procedures Act, the Fair Credit Reporting Act and the Federal Trade Commission Act, among others. These laws and regulations mandate certain disclosure requirements and regulate the manner in which financial institutions must deal with customers when taking deposits or making loans to such customers. The Bank must comply with the applicable provisions of these consumer protection laws and regulations as part of its ongoing customer relations.

Community Reinvestment Act: The Community Reinvestment Act (“CRA”) requires that, in connection with examinations of financial institutions within its jurisdiction, the FDIC shall evaluate the record of the financial institutions in meeting the credit needs of their local communities, including low and moderate income neighborhoods, consistent with the safe and sound operation of those institutions. These factors are also considered in evaluating mergers, acquisitions, and applications to open a branch or facility. The Bank has a satisfactory rating under CRA.

USA Patriot Act: The Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (the "USA PATRIOT Act") requires each financial institution to: (i) establish an anti-money laundering program; (ii) establish due diligence policies, procedures and controls with respect to its private banking accounts and correspondent banking accounts involving foreign individuals and certain foreign banks; and (iii) implement certain due diligence policies, procedures and controls with regard to correspondent accounts in the United States for, or on behalf of, a foreign bank that does not have a physical presence in any country. In addition, the USA PATRIOT Act contains a provision encouraging cooperation among financial institutions, regulatory authorities and law enforcement authorities with respect to individuals, entities and organizations engaged in, or reasonably suspected of engaging in, terrorist acts or money laundering activities.

Commercial Real Estate Lending: The Bank’s lending operations may be subject to enhanced scrutiny by federal banking regulators based on its concentration of commercial real estate loans. On December 6, 2006, the federal banking regulators issued final guidance to remind financial institutions of the risk posed by commercial real estate (“CRE”) lending concentrations. CRE loans generally include land development, construction loans, and loans secured by multifamily property, and non-farm, nonresidential real property where the primary source of repayment is derived from rental income associated with the property. The guidance prescribes the following guidelines for its examiners to help identify institutions that are potentially exposed to significant CRE risk, including concentrations in certain types of CRE that may warrant greater supervisory scrutiny: total reported loans for construction, land development, and other land represent 100% or more of the institutions total capital; or total commercial real estate loans represent 300% or more of the institution’s total capital, and the outstanding balance of the institution’s commercial real estate loan portfolio has increased by 50% or more.

Financial Regulatory Reform

On July 21, 2010, the President signed into law the Dodd-Frank Act, which contains a comprehensive set of provisions designed to govern the practices and oversight of financial institutions and other participants in the financial markets. The Dodd-Frank Act made extensive changes in the regulation of financial institutions and their holding companies.

Uncertainty remains as to the ultimate impact of the Dodd-Frank Act, which could have a material adverse impact on the financial services industry as a whole or on ours and the Bank’s business, results of operations, and financial condition. Many aspects of the Dodd-Frank Act are subject to rulemaking and will take effect over several years, making it difficult to anticipate the overall financial impact on the Company, its customers or the financial industry

8

more generally. However, it is likely that the Dodd-Frank Act will increase the regulatory burden, compliance costs and interest expense for the Company and Bank. Some of the rules that have been adopted to comply with the Dodd-Frank Act's mandates are discussed below.

Consumer Financial Protection Bureau: The Dodd-Frank Act centralized responsibility for consumer financial protection including implementing, examining and enforcing compliance with federal consumer financial laws with Consumer Financial Protection Bureau (the “CFPB”). Depository institutions with less than $10 billion in assets, such as our Bank, will be subject to rules promulgated by the CFPB but will continue to be examined and supervised by federal banking regulators for consumer compliance purposes.

UDAP and UDAAP: 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. The law of choice for enforcement against such business practices has been Section 5 of the Federal Trade Commission Act-the primary federal law that prohibits unfair or deceptive acts or practices and unfair methods of competition in or affecting commerce ("UDAP" or "FTC Act"). "Unjustified consumer injury" is the principal focus of the FTC Act. Prior to the Dodd-Frank Act, there was little formal guidance to provide insight to the parameters for compliance with the UDAP law. However, the UDAP provisions have been expanded under the Dodd-Frank Act to apply to "unfair, deceptive or abusive acts or practices" ("UDAAP"), which has been delegated to the CFPB for supervision. The CFPB has published its first Supervision and Examination Manual that addresses compliance with and the examination of UDAAP.

Mortgage Reform: The CFPB has adopted final rules implementing minimum standards for the origination of residential mortgages, including standards regarding a customer's ability to repay, restricting variable-rate lending by requiring that the ability to repay variable-rate loans be determined by using the maximum rate that will apply during the first five years of a variable-rate loan term, and making more loans subject to provisions for higher cost loans, new disclosures, and certain other revisions. In addition, the Dodd-Frank Act allows borrowers to raise certain defenses to foreclosure if they receive any loan other than a “qualified mortgage” as defined by the CFPB.

Deposit Insurance and Assessments: The $250,000 limit for federal deposit insurance for noninterest-bearing demand transaction accounts at all insured depository institutions was made permanent by the Dodd-Frank Act. The Dodd-Frank Act also changed the assessment base for federal deposit insurance from the amount of insured deposits to consolidated assets less tangible capital, eliminated the ceiling on the size of the Deposit Insurance Fund (“DIF”), and increased the floor on the size of the DIF, which generally will require an increase in the level of assessments for institutions with assets in excess of $10 billion.

Demand Deposits: The Dodd-Frank Actrepealed the federal prohibitions on the payment of interest on demand deposits, thereby permitting depository institutions to pay interest on business transactions and other accounts.

Interchange Fees: The Federal Reserve has issued final rules limiting the amount of any debit card interchange fee that an issuer may receive or charge with respect to electronic debit card transactions to be reasonable and proportional to the cost incurred by the issuer with respect to the transaction.

Volcker Rule: On December 10, 2013, the federal regulators adopted final regulations to implement the proprietary trading and private fund prohibitions of the Volcker Rule under the Dodd-Frank Act. Under the final regulations, which will become effective on April 1, 2014, banking entities are generally prohibited, subject to significant exceptions from: (i) short-term proprietary trading as principal in securities and other financial instruments, and (ii) sponsoring or acquiring or retaining an ownership interest in private equity and hedge funds. The Federal Reserve has granted an extension for compliance with the Volcker Rule until July 21, 2015. The Company is reviewing the impact of the Volcker Rule on its investment portfolio.

Many of the provisions of the Dodd-Frank Act are subject to delayed effective dates or require the adoption of further implementing regulations and, therefore, their impact on the Company’s operations cannot be fully determined at this time.

BASEL III

On July 2, 2013, the Federal Reserve approved a final rule to establish a new comprehensive regulatory capital framework for all US banking organizations. On July 9, 2013, the final rule was approved (as an interim final rule) by the FDIC. The Regulatory Capitol Framework (Basel III) implements several changes to the US regulatory capital framework required by the Dodd-Frank Act. The new US capital framework imposes higher minimum capital requirements, additional capital buffers above those minimum requirements, a more restrictive definition of capital, and higher risk weights for various enumerated classifications of assets, the combined impact of which effectively results in substantially more demanding capital standards for US banking organizations.

The Basel III final rule establishes a new common equity Tier 1 capital (“CET1”) requirement, an increase in the Tier 1 capital requirement from 4.0% to 6.0% and maintains the current 8.0% total capital requirement. The new CET1 and minimum Tier 1 capital requirements are effective January 1, 2015. In addition to these minimum risk-based capital ratios, the Basel III final rule requires that all banking organizations maintain a “capital conservation buffer” consisting of common equity Tier 1 capital (“CET1”) in an amount equal to 2.5% of risk-weighted assets in order to avoid restrictions on their ability to make capital distributions and to pay certain discretionary bonus payments to executive officers. In order to avoid those restrictions, the capital conservation buffer effectively increases the minimum CET1 capital, Tier 1 capital, and total capital ratios for US banking organizations to 7.0%, 8.5%, and 10.5%, respectively. Banking organizations with capital levels that fall within the buffer will be required to limit dividends, share repurchases or redemptions (unless replaced within the same calendar quarter by capital instruments of equal or higher quality), and discretionary bonus payments. The capital conservation buffer is phased in over a 5-year period beginning January 1, 2016.

As required by Dodd-Frank, the Basel III final rule requires that capital instruments such as trust preferred securities and cumulative preferred shares be phased-out of Tier 1 capital by January 1, 2016, for banking organizations that had $15 billion or more in total consolidated assets as of December 31, 2009 and grandfathers as Tier 1 capital such instruments issued by these smaller entities prior to May 19, 2010 (provided they do not exceed 25 percent of Tier 1 capital). The Company’s trust preferred securities are grandfathered under this provision.

The Basel III final rule provides banking organizations under $250 billion in total consolidated assets or under $10 billion in foreign exposures with a one-time “opt-out” right to continue excluding Accumulated Other Comprehensive Income from CET1 capital. The election to opt out must be made on the banking organization’s first Call Report filed after January 1, 2015.

The Basel III final rule requires that goodwill and other intangible assets (other than mortgage servicing assets), net of associated deferred tax liabilities (“DTLs”), be deducted from CET1 capital. Additionally, deferred tax assets (“DTAs”) that arise from net operating loss and tax credit carryforwards, net of associated DTLs and valuation allowances, are fully deducted from CET1 capital. However, DTAs arising from temporary differences that could not be realized through net operating loss carrybacks, along with mortgage servicing assets and “significant” (defined as greater than 10% of the issued and outstanding common stock of the unconsolidated financial institution) investments in the common stock of unconsolidated “financial institutions” are partially includible in CET1 capital, subject to deductions defined in the final rule.

Based on a preliminary assessment of the impact of Basel III and in consideration of the capital plan for the Company, management of the Company anticipates that the Company and Bank will be in compliance with the Basel III guidelines within the implementation periods.

Employees

At December 31, 2013, we had approximately 455 full-time equivalent employees. None of the Company's employees are covered by a collective bargaining agreement. Management believes that its relationship with its employees is good.

ITEM 1A: RISK FACTORS

An investment in our common shares is subject to risks inherent to our business. 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 in this report. The risks and uncertainties described below are not the only ones we face. Although we have significant risk management policies, procedures and verification processes in place, additional risks and uncertainties that management is not aware of or focused on or that management currently deems immaterial may also materially and adversely impair our business operations. The value of our common shares could decline due to any of these risks, and you could lose all or part of your investment.

Risks Relating to Our Business

Our allowance for loan losses may not be adequate to cover actual loan losses.

We maintain an allowance for loan losses, which is a reserve established through a provision for loan losses charged to expense, that represents management's estimate of probable losses within the existing portfolio of loans. The allowance, in the judgment of management, is sufficient to reserve for estimated loan losses and risks inherent in the loan portfolio. We continue to monitor the adequacy of our loan loss allowance and may need to increase it if economic conditions deteriorate. In addition, bank regulatory agencies periodically review our allowance for loan losses and may require an increase in the provision for loan losses or the recognition of further loan charge-offs, based on judgments that can differ somewhat from those of our own management. In addition, if charge-offs in future periods exceed the allowance for loan losses (i.e., if the loan allowance is inadequate), we may need additional loan loss provisions to increase the allowance for loan losses. Additional provisions to increase the allowance for loan losses, should they become necessary, would result in a decrease in net income and a reduction in capital, and may have a material adverse effect on our financial condition and results of operations.

An economic downturn, especially one affecting our market areas, could adversely affect our financial condition, results of operations or cash flows.

Our success depends upon the economic prosperity in our primary market areas. If the communities in which we operate do not grow, or if prevailing economic conditions locally or nationally are unfavorable, our business may not succeed. Unpredictable economic conditions may have an adverse effect on the quality of our loan portfolio and our financial performance. Economic recession over a prolonged period or other economic problems in our market areas could have a material adverse impact on the quality of the loan portfolio and the demand for our products and services. Future adverse changes in the economies in our market areas may have a material adverse effect on our financial condition, results of operations or cash flows. As a community bank, we bear increased risk of unfavorable local economic conditions. Moreover, we cannot give any assurance that we will benefit from any market growth or favorable economic conditions in our primary market areas even if they do occur.

Our loan portfolio is concentrated in certain markets which could result in increased credit risk.

Substantially all of our loans are to businesses and individuals in the St. Louis, Kansas City, and Phoenix metropolitan areas. The regional economic conditions in areas where we conduct our business have an impact on the demand for our products and services as well as the ability of our customers to repay loans, the value of the collateral securing loans, and the stability of our deposit funding sources. Consequently, a decline in local economic conditions may adversely affect our earnings.

Our loan portfolio mix, which has a concentration of loans secured by real estate, could result in increased credit risk.

A significant portion of our portfolio is secured by real estate and thus we face a high degree of risk from a downturn in our real estate markets. If real estate values would decline further in our markets, the value of real estate collateral securing our loans could be significantly reduced. Our ability to recover on defaulted loans for which the primary reliance for repayment is on the real estate collateral by foreclosing and selling that real estate would then be diminished, and we would be more likely to suffer losses on defaulted loans.

Additionally, because Kansas is a judicial foreclosure state, all foreclosures must be processed through the Kansas state courts. Due to this process, it takes approximately one year for us to foreclose on real estate collateral located

11

in the State of Kansas. Our ability to recover on defaulted loans secured by Kansas property may be delayed and our recovery efforts are lengthened due to this process.

We face potential risks from litigation brought against the Company or the Bank.

We are involved in various lawsuits and legal proceedings. Pending or threatened litigation against the Company or the Bank, litigation-related costs and any legal liability as a result of an adverse determination with respect to one or more of these legal proceedings could have a material adverse effect on our business, cash flows, financial position or results of operations and/or could cause us significant reputational harm, including without limitation as a result of negative publicity the Company may face even if it prevails in such legal proceedings, which could adversely affect our business prospects.

Liquidity risk could impair our ability to fund operations and jeopardize our financial condition.

Liquidity is essential to our business.  An inability to raise funds through deposits, borrowings, the sale of investment securities and other sources could have a substantial material adverse effect on our liquidity.  Our access to funding sources in amounts that are adequate to finance our activities could be impaired by factors that affect us specifically or the financial services industry in general.  Factors that could detrimentally impact our access to liquidity sources include but are not limited to a decrease in the level of our business activity due to a market downturn, our failure to remain well capitalized, or adverse regulatory action against us. Our ability to acquire deposits or borrow could also be impaired by factors that are not specific to us, such as a severe disruption of the financial markets or negative views and expectations about the prospects for the financial services industry as a whole.

Our business is subject to interest rate risk and variations in interest rates may negatively affect our financial performance.

A substantial portion of our income is derived from the differential or “spread” between the interest earned on loans, investment securities and other interest-earning assets, and the interest paid on deposits, borrowings and other interest-bearing liabilities. Because of the differences in the maturities and repricing characteristics of our interest-earning assets and interest-bearing liabilities, changes in interest rates do not produce equivalent changes in interest income earned on interest-earning assets and interest paid on interest-bearing liabilities. Significant fluctuations in market interest rates could materially and adversely affect not only our net interest spread, but also our asset quality and loan origination volume, and/or net income.

We face potential risk from changes in Governmental Monetary Policies.

The Bank’s earnings are affected by domestic economic conditions and the monetary and fiscal policies of the United States government and its agencies. The Federal Reserve’s monetary policies have had, and are likely to continue to have, an important impact on the operating results of commercial banks through its power to implement national monetary policy in order, among other things, to curb inflation or combat a recession. The monetary policies of the Federal Reserve, including its ongoing “Quantitative Easing” program, affect the levels of bank loans, investments, and deposits through its control over the issuance of United States government securities, its regulation of the discount rate applicable to member banks, and its influence over reserve requirements to which member banks are subject. The Bank cannot predict the nature or impact of future changes in monetary and fiscal policies.

Deferred tax assets may not be realizable and we may be required to establish a valuation allowance against the deferred income tax assets, which could have a material adverse effect on our results of operations and financial condition.

Deferred tax represents the tax effect of the differences between the book and tax basis of assets and liabilities. Deferred tax assets are assessed periodically by management to determine if they are realizable. If based on available information, it is not more likely than not that the deferred income tax asset will be realized, then a valuation allowance must be established with a corresponding charge to net income. Future facts and circumstances may require a valuation allowance. Charges to establish a valuation allowance could have a material adverse effect on our results of operations and financial position.

12

If the Bank incurs losses that erode its capital, it may become subject to enhanced regulation or supervisory action.

Under federal and state laws and regulations pertaining to the safety and soundness of insured depository institutions, the Missouri Division of Finance and the Federal Reserve, and separately the FDIC as insurer of the Bank's deposits, have the authority to compel or restrict certain actions if the Company's or the Bank's capital should fall below adequate capital standards as a result of future operating losses, or if its bank regulators determine that it has insufficient capital. Among other matters, the corrective actions include but are not limited to requiring affirmative action to correct any conditions resulting from any violation or practice; directing an increase in capital and the maintenance of specific minimum capital ratios; restricting the Bank's operations; limiting the rate of interest the bank may pay on brokered deposits; restricting the amount of distributions and dividends and payment of interest on its trust preferred securities; requiring the Bank to enter into informal or formal enforcement orders, including memoranda of understanding, written agreements and consent or cease and desist orders to take corrective action and enjoin unsafe and unsound practices; removing officers and directors and assessing civil monetary penalties; and taking possession of and closing and liquidating the Bank. These actions may limit the ability of the Bank or Company to execute its business plan and thus can lead to an adverse impact on the the results of operations or financial position.

Changes in government regulation and supervision may increase our costs.

Our operations are subject to extensive regulation by federal, state and local governmental authorities and are subject to various laws and judicial and administrative decisions imposing requirements and restrictions on part or all of our operations.Banking regulations are primarily intended to protect depositors' funds, federal deposit insurance funds and the banking system as a whole, not stockholders. Because our business is highly regulated, the laws, rules, regulations and supervisory guidance and policies applicable to us are subject to regular modification and change and could result in an adverse impact on our results of operations.

Any future increases in FDIC insurance premiums might adversely impact our earnings.

Over the past several years, the FDIC has adopted several rules which have resulted in a number of changes to the FDIC assessments, including modification of the assessment system and a special assessment. It is possible that the FDIC may impose additional special assessments in the future or further increase our annual assessment, which could adversely affect our earnings.

We may be adversely affected by the soundness of other financial institutions.

Financial services institutions are interrelated as a result of trading, clearing, counterparty or other relationships. We have exposure to different institutions and counterparties, and we execute transactions with various counterparties in the financial industry, including federal home loan banks, commercial banks, brokers and dealers, investment banks and other institutional clients. Defaults by financial services institutions, and even rumors or questions about one or more financial services institutions or the financial services industry in general, have led to market-wide liquidity problems in prior years and could lead to losses or defaults by us or by other institutions. Any such losses could materially and adversely affect our results of operations or financial position.

We face significant competition.

The financial services industry, including commercial banking, mortgage banking, consumer lending, and home equity lending, is highly competitive, and we encounter strong competition for deposits, loans, and other financial services in all of our market areas in each of our lines of business. Our principal competitors include other commercial banks, savings banks, savings and loan associations, mutual funds, money market funds, finance companies, trust companies, insurers, credit unions, and mortgage companies among others. Many of our non-bank competitors are not subject to the same degree of regulation as us and have advantages over us in providing certain services. Many of our competitors are significantly larger than us and have greater access to capital and other resources. Also, our ability to compete effectively in our business is dependent on our ability to adapt successfully to regulatory and technological changes within the banking and financial services industry, generally. If we are unable to compete effectively, we will lose market share and our income from loans and other products may diminish.

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

• the ability to develop, maintain, and build upon long-term customer relationships based on top quality service and high ethical standards;

• the scope, relevance, and pricing of products and services offered to meet customer needs and demands;

13

• the rate at which we introduce new products and services relative to our competitors;

• customer satisfaction with our level of service; and/or

• industry and general economic trends.

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

We have engaged in and may continue to engage in further expansion through acquisitions, including FDIC-assisted transactions, which could negatively affect our business and earnings.

Our earnings, financial condition, and prospects after a merger or acquisition depend in part on our ability to successfully integrate the operations of the acquired company. We may be unable to integrate operations successfully or to achieve expected results or cost savings.

Acquiring other banks or businesses involves various risks commonly associated with acquisitions, including, among other things:

• potential exposure to unknown or contingent liabilities of the target company;

• exposure to potential asset quality issues of the target company;

• difficulty and expense of integrating the operations and personnel of the target company;

• potential disruption to our business;

• potential diversion of our management's time and attention;

• the possible loss of key employees and customers of the target company;

• difficulty in estimating the value of the target company; and/or

• potential changes in banking or tax laws or regulations that may affect the target company.

We periodically evaluate merger and acquisition opportunities and conduct due diligence activities related to possible transactions with other financial institutions and financial services companies. As a result, merger or acquisition discussions and, in some cases, negotiations may take place, and future mergers or acquisitions involving cash, debt or equity securities may occur at any time. Acquisitions may involve the payment of a premium over book and/or 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. Furthermore, failure to realize the expected revenue increases, cost savings, reimbursements of losses from the FDIC, increases in geographic or product presence, and/or other projected benefits from an acquisition could have a material adverse effect on our financial condition and results of operations. Finally, to the extent that we issue capital stock in connection with transactions, such transactions and related stock issuances may have a dilutive effect on earnings per share of our common stock and share ownership of our stockholders.

Our ability to continue to receive the benefits of our loss share arrangements with the FDIC is conditioned upon our compliance with certain requirements under the agreements.

We are the beneficiary of a loss share agreement with the FDIC that calls for the FDIC to fund a portion of our losses on loss share assets we acquired in connection with our FDIC-assisted transactions. To recover a portion of our losses and retain the loss share protection, we must comply with certain requirements imposed by the agreement. The requirements of the agreement relate primarily to our administration of the assets covered by the agreement, as well as our obtaining the consent of the FDIC to engage in certain corporate transactions that may be deemed under the agreements to constitute a transfer of the loss share benefits. When the consent of the FDIC is required under the loss share agreement, the FDIC may withhold its consent or may condition its consent on terms that we do not find acceptable. If the FDIC does not grant its consent to a transaction we would like to pursue, or conditions its consent on terms that we do not find acceptable, we may be unable to engage in a corporate transaction that might otherwise benefit our shareholders or we may elect to pursue such a transaction without obtaining the FDIC's consent, which could result in termination of our loss share agreement with the FDIC.

Our loss sharing arrangements with the FDIC will not cover all of our losses on loans we acquired.

Although we have entered into a loss share agreement with the FDIC that provides that the FDIC will bear a significant portion of losses related to specified loan portfolios that we acquired, we are not protected for all losses resulting from

14

charge-offs with respect to those specified loan portfolios. Additionally, the loss sharing agreements have limited terms. Therefore, the FDIC will not reimburse us for any charge-off or related losses that we experience after the term of the loss share agreement, and any such charge-offs would negatively impact our net income. Moreover, the loss share provisions in the loss share agreement may be administered improperly, or the FDIC may interpret those provisions in a way different that we do. In any of those events, our losses could increase.

We may not be able to attract and retain skilled people.

Our success depends, in large part, on our ability to attract and retain key people. Competition for the best people in most activities in which we are engaged can be intense, and we may not be able to hire or retain the people we want and/or need. Although we maintain employment agreements with certain key employees, and have incentive compensation plans aimed, in part, at long-term employee retention, the unexpected loss of services of one or more of our key personnel could still occur, and such events may have a material adverse impact on our business because of the loss of the employee's skills, knowledge of our market, and years of industry experience and the difficulty of promptly finding qualified replacement personnel.

We may need to raise additional capital in the future, and such capital may not be available to us or may only be available on unfavorable terms.

We may need to raise additional capital in the future in order to support any additional provisions for loan losses and loan charge-offs, to maintain our capital ratios, or for other reasons. The condition of the financial markets may be such that we may not be able to obtain additional capital, or the additional capital may only be available on terms that are not attractive to us.

Recently enacted financial reform legislation and rules promulgated thereunder may adversely affect us.

The Dodd-Frank Act was signed into law by President Obama on July 21, 2010. The Dodd-Frank Act represents a comprehensive overhaul of the financial services industry within the United States, establishes the new federal Consumer Financial Protection Bureau (the “CFPB”), and will require the CFPB and other federal agencies to implement many new rules.

The CFPB has broad powers to supervise and enforce consumer protection laws. The CFPB has broad rule-making authority for a wide range of consumer protection laws that apply to all banks, including the authority to prohibit unfair, deceptive or abusive acts and practices. In addition, the Dodd-Frank Act enhanced the regulation of mortgage banking and gave to the CFPB oversight of many of the core laws which regulate the mortgage industry and the authority to implement mortgage regulations. New regulations adopted and anticipated to be adopted by the CFPB will significantly impact consumer mortgage lending and servicing.

The Dodd-Frank Act and the resulting regulations will likely affect the Company's business and operations in other ways which are difficult to predict at this time. However, compliance with these new laws and regulations will result in additional costs, which may adversely impact the Company's results of operations, financial condition or liquidity, any of which may impact the market price of the Company's common stock.

The CFPB’s "qualified mortgage" rules could have a negative impact on our loan origination process and foreclosure proceedings.

The CFPB has adopted rules that are likely to impact our residential mortgage lending practices, and the residential mortgage market generally, through rules that implement minimum standards for the origination of residential mortgages, including standards regarding a customer’s ability to repay, restricting variable-rate lending, and making more loans subject to provisions for higher cost loans, new disclosures, and certain other revisions. Although new "qualified mortgage" rules may provide better definition and more certainty regarding regulatory requirements, the rules may also increase our compliance burden and reduce our lending flexibility and discretion, which could negatively impact our ability to originate new loans and the cost of originating new loans. Any loans that we make outside of the "qualified mortgage" criteria could expose us to an increased risk of liability and reduce or delay our ability to foreclose on the underlying property. It is difficult to predict how the CFPB''s "qualified mortgage" rules will impact us, but any decreases in loan origination volume or increases in compliance and foreclosure costs could negatively affect our business, operating results and financial condition.

15

The CFPB may reshape the consumer financial laws through rulemaking and enforcement of unfair, deceptive or abusive acts or practices, which may directly impact the business operations of depository institutions offering consumer financial products or services including the Bank.

The CFPB has broad rulemaking authority to administer and carry out the purposes and objectives of the "Federal consumer financial laws, and to prevent evasions thereof," with respect to all financial institutions that offer financial products and services to consumers. The CFPB is also authorized to prescribe rules applicable to any covered person or service provider identifying and prohibiting acts or practices that are "unfair, deceptive, or abusive" in connection with any transaction with a consumer for a consumer financial product or service, or the offering of a consumer financial product or service. The potential reach of the CFPB's broad new rulemaking powers and UDAAP authority on the operations of financial institutions offering consumer financial products or services including the Bank is currently unknown.

The Volcker Rule limits the permissible strategies for managing our investment portfolio.

Effective December 10, 2013, pursuant to the Dodd-Frank Act, federal banking and securities regulators issued final rules to implement Section 619 of the Dodd-Frank Act (the "Volcker Rule"). Generally, subject to a transition period and certain exceptions, the Volcker Rule restricts insured depository institutions and their affiliated companies from: (i) short-term proprietary trading as principal in securities and other financial instruments, and (ii) sponsoring or acquiring or retaining an ownership interest in private equity and hedge funds. After the transition period, the Volcker Rule prohibitions and restrictions will apply to banking entities, including the Company, unless an exception applies. We are analyzing the impact of the Volcker Rule on our investment portfolio and changes to our investment strategies may occur, which could negatively affect our earnings.

The Federal Reserve has adopted new capital requirements for financial institutions that may require us to retain or raise additional capital or and/or reduce dividends.

On July 2, 2013, the Federal Reserve adopted final rules that, when effective, will increase regulatory capital requirements, implement changes required by the Dodd-Frank Act and implement portions of the Basel III regulatory capital reforms. In the future, the capital requirements for bank holding companies may require us to retain or raise additional capital, restrict our ability to pay dividends and repurchase shares of our common stock, restrict our ability to provide certain forms of discretionary executive compensation and/or require other changes to our strategic plans. The rules could restrict our ability to grow and implement our future business strategies, which could have an adverse impact on our results of operations.

A failure in or breach of our operational or security systems, or those of our third party service providers, including as a result of cyber attacks, could disrupt our business, result in unintentional disclosure or misuse of confidential or proprietary information, damage our reputation, increase our costs and adversely impact our earnings.

As a financial institution, our operations rely heavily on the secure processing, storage and transmission of confidential and other information on our computer systems and networks.  Any failure, interruption or breach in security or operational integrity of these systems could result in failures or disruptions in our Internet banking system, treasury management products, check and document imaging, remote deposit capture systems, general ledger, and other systems. The security and integrity of our systems could be threatened by a variety of interruptions or information security breaches, including those caused by computer hacking, cyber attacks, electronic fraudulent activity or attempted theft of financial assets.  We cannot assure you that any such failures, interruption or security breaches will not occur, or if they do occur, that they will be adequately addressed.  While we have certain protective policies and procedures in place, the nature and sophistication of the threats continue to evolve.  We may be required to expend significant additional resources in the future to modify and enhance our protective measures. Additionally, we face the risk of operational disruption, failure, termination or capacity constraints of any of the third parties that facilitate our business activities, including exchanges, clearing agents, clearing houses or other financial intermediaries.  Such parties could also be the source of an attack on, or breach of, our operational systems.  Any failures, interruptions or security breaches in our information systems could damage our reputation, result in a loss of customer business, result in a violation of privacy or other laws, or expose us to civil litigation, regulatory fines or losses not covered by insurance.

We are subject to environmental risks associated with owning real estate or collateral.

When a borrower defaults on a loan secured by real property, the Bank may purchase the property in foreclosure or accept a deed to the property surrendered by the borrower. We may also take over the management of commercial properties whose owners have defaulted on loans. We may also own and lease premises where branches and other facilities are located. While we will have lending, foreclosure and facilities guidelines intended to exclude properties with an unreasonable risk of contamination, hazardous substances could exist on some of the properties that the Bank may own, manage or occupy. We face the risk that environmental laws could force us to clean up the properties at the Company's expense. The cost of cleaning up or paying damages and penalties associated with environmental problems could increase our operating expenses. It may cost much more to clean a property than the property is worth. We could also be liable for pollution generated by a borrower's operations if the Bank takes a role in managing those operations after a default. The Bank may also find it difficult or impossible to sell contaminated properties.

Risks Relating to Our Common Stock

The price of our common stock may be volatile or may decline.

The trading price of our common stock may fluctuate widely as a result of a number of factors, many of which are outside our control. In addition, the stock market is subject to fluctuations in the share prices and trading volumes that affect the market prices of the shares of many companies. These broad market fluctuations could make it more difficult for you to resell your common stock when you want and at prices you find attractive. Our stock price can fluctuate significantly in response to a variety of factors including, among other things:

• actual or anticipated quarterly fluctuations in our operating results and financial condition;

• changes in revenue or earnings estimates or publication of research reports and recommendations by financial analysts;

• failure to meet analysts' revenue or earnings estimates;

• speculation in the press or investment community;

• strategic actions by us or our competitors, such as acquisitions or restructurings;

• actions by institutional stockholders;

• fluctuations in the stock prices and operating results of our competitors;

• general market conditions and, in particular, developments related to market conditions for the financial services industry;

• proposed or adopted regulatory changes or developments;

• anticipated or pending investigations, proceedings or litigation that involve or affect us; and/or

• domestic and international economic factors unrelated to our performance.

The stock market and, in particular, the market for financial institution stocks, has experienced significant volatility over the last several years. As a result, the market price of our common stock may be volatile. In addition, the trading volume in our common stock may fluctuate more than usual and cause significant price variations to occur. The trading price of the shares of our common stock and the value of our other securities will depend on many factors, which may change from time to time, including, without limitation, our financial condition, performance, creditworthiness and prospects, future sales of our equity or equity related securities, and other factors identified in this annual report and other reports by the Company. In some cases, the markets have produced downward pressure on stock prices and credit availability for certain issuers without regard to those issuers' underlying financial strength or operating results. A significant decline in our stock price could result in substantial losses for individual stockholders and could lead to costly and disruptive securities litigation.

An investment in our common stock is not insured and you could lose the value of your entire investment.

An investment in our common stock is not a savings account, deposit or other obligation of our bank subsidiary, any non-bank subsidiary or any other bank, and such investment is not insured or guaranteed by the FDIC or any other governmental agency. As a result, if you acquire our common stock, you may lose some or all of your investment.

17

Our ability to pay dividends is limited by various statutes and regulations and depends primarily on the Bank's ability to distribute funds to us, and is also limited by various statutes and regulations.

The Company depends on payments from the Bank, including dividends, management fees and payments under tax sharing agreements, for substantially all of the Company's revenue. Federal and state regulations limit the amount of dividends and the amount of payments that the Bank may make to the Company under tax sharing agreements. In certain circumstances, the Missouri Division of Finance, FDIC, or Federal Reserve could restrict or prohibit the Bank from distributing dividends or making other payments to us. In the event that the Bank was restricted from paying dividends to the Company or making payments under the tax sharing agreement, the Company may not be able to service its debt, pay its other obligations or pay dividends on its common stock. If we are unable or determine not to pay dividends on our outstanding equity securities, the market price of such securities could be materially adversely affected.

There can be no assurance of any future dividends on our common stock.

Holders of our common stock are entitled to receive dividends only when, as and if declared by our board of directors. Although we have historically paid cash dividends on our common stock, we are not required to do so.

There may be future sales or other dilution of our equity, which may adversely affect the market price of our common stock.

We are not restricted from issuing additional common stock or preferred stock, including any securities that are convertible into or exchangeable for, or that represent the right to receive, common stock or preferred stock or any substantially similar securities.

In addition, to the extent options to purchase common stock under our employee stock option plans are exercised, or shares are issued, holders of our common stock could incur additional dilution. Further, if we sell additional equity or convertible debt securities, such sales could result in increased dilution to our stockholders. The market price of our common stock could decline as a result of sales of a large number of shares of common stock or preferred stock or similar securities in the market after an offering or the perception that such sales could occur.

Our outstanding debt securities restrict our ability to pay dividends on our capital stock.

We have outstanding subordinated debentures issued to statutory trust subsidiaries, which have issued and sold preferred securities in the Trusts to investors.

If we are unable to make payments on any of our subordinated debentures for more than 20 consecutive quarters, we would be in default under the governing agreements for such securities and the amounts due under such agreements would be immediately due and payable. Additionally, if for any interest payment period we do not pay interest in respect of the subordinated debentures (which will be used to make distributions on the trust preferred securities), or if for any interest payment period we do not pay interest in respect of the subordinated debentures, or if any other event of default occurs, then we generally will be prohibited from declaring or paying any dividends or other distributions, or redeeming, purchasing or acquiring, any of our capital securities, including the common stock, during the next succeeding interest payment period applicable to any of the subordinated debentures, or next succeeding interest payment period, as the case may be.

Moreover, any other financing agreements that we enter into in the future may limit our ability to pay cash dividends on our capital stock, including the common stock. In the event that our existing or future financing agreements restrict our ability to pay dividends in cash on the common stock, we may be unable to pay dividends in cash on the common stock unless we can refinance amounts outstanding under those agreements. In addition, if we are unable or determine not to pay interest on our subordinated debentures, the market price of our common stock could be materially or adversely affected.

Anti-takeover provisions could negatively impact our stockholders.

Provisions of Delaware law and of our certificate of incorporation, as amended, and bylaws, as well as various provisions of federal and Missouri state law applicable to bank and bank holding companies, could make it more difficult for a third party to acquire control of us or have the effect of discouraging a third party from attempting to acquire control of us. We are subject to Section 203 of the Delaware General Corporation Law, which would make it more difficult

18

for another party to acquire us without the approval of our board of directors. Additionally, our certificate of incorporation, as amended, authorizes our board of directors to issue preferred stock which could be issued as a defensive measure in response to a takeover proposal. In the event of a proposed merger, tender offer or other attempt to gain control of the Company, our board of directors would have the ability to readily issue available shares of preferred stock as a method of discouraging, delaying or preventing a change in control of the Company. Such issuance could occur whether or not our stockholders favorably view the merger, tender offer or other attempt to gain control of the Company. These and other provisions could make it more difficult for a third party to acquire us even if an acquisition might be in the best interests of our stockholders. Although we have no present intention to issue any shares of our authorized preferred stock, there can be no assurance that the Company will not do so in the future.

ITEM 2: PROPERTIES

Banking facilities

Our executive offices are located at 150 North Meramec, Clayton, Missouri, 63105. As of December 31, 2013, we had six banking locations and a support center in the St. Louis metropolitan area, eight banking facilities in the Kansas City metropolitan area, and two banking locations in the Phoenix metropolitan area. We own three of the facilities and lease the remainder. Most of the leases expire between 2014 and 2022 and include one or more renewal options of 5 years. One lease expires in 2028. All the leases are classified as operating leases. We are actively pursuing a sublease arrangement for one of our banking locations in the Kansas City market that was closed in 2013. We believe all our properties are in good condition.

Wealth management facilities

Our Wealth Management operations are headquartered in approximately 11,000 square feet of commercial condominium space in Clayton, Missouri, located approximately two blocks from our executive offices. Enterprise Trust also has offices in two of our banking locations in Kansas City. Expenses related to the space used by Enterprise Trust are allocated to the Wealth Management segment.

ITEM 3: LEGAL PROCEEDINGS

The Company and its subsidiaries are, from time to time, parties to various legal proceedings arising out of their businesses. Management believes that there are no such proceedings pending or threatened against the Company or its subsidiaries which, if determined adversely, would have a material adverse effect on the business, consolidated financial condition, results of operations or cash flows of the Company or any of its subsidiaries.

ITEM 5: MARKET FOR REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Common Stock Market Prices

The Company's common stock trades on the NASDAQ Global Select Market under the symbol “EFSC”. Below are the dividends declared by quarter along with what the Company believes are the high and low sales prices for the common stock for the periods indicated, as reported by the NASDAQ Global Select Market. There may have been other transactions at prices not known to the Company. As of March 3, 2014, the Company had 479 common stock shareholders of record and a market price of $18.63 per share. The number of holders of record does not represent the actual number of beneficial owners of our common stock because securities dealers and others frequently hold shares in “street name” for the benefit of individual owners who have the right to vote shares.

Dividends

The holders of shares of our common stock are entitled to receive dividends when declared by our Board of Directors out of funds legally available for the purpose of paying dividends. Our ability to pay dividends is substantially dependent upon the ability of our subsidiaries to pay cash dividends to us. Information on regulatory restrictions on our ability to pay dividends is set forth in Part I- Item 1. Business - Supervision and Regulation - Financial Holding Company - Dividend Restrictions. The amount of dividends, if any, that may be declared by the Company also depends on many other factors, including future earnings, bank regulatory capital requirements and business conditions as they affect the Company and its subsidiaries. As a result, no assurance can be given that dividends will be paid in the future with respect to our common stock.

ITEM 7: MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND

RESULTS OF OPERATIONS

Introduction

The objective of this section is to provide an overview of the results of operations and financial condition of the Company for the three years ended December 31, 2013. It should be read in conjunction with the Consolidated Financial Statements, Notes and other financial data presented elsewhere in this report, particularly the information regarding the Company's business operations described in Item 1.

Executive Summary

This overview of management's discussion and analysis highlights selected information in this document and may not contain all of the information that is important to you. For a more complete understanding of trends, events, commitments, uncertainties, liquidity, capital resources and critical accounting estimates, you should carefully read this entire document. Results and corresponding ratios for the years ended December 31, 2012 and 2011 have been reclassified to reflect the adoption of ASU 2014-1 "Investments-Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects." The impact of ASU 2014-1 was a decrease to Other Non-interest Expense and a similar increase to Income Tax Expense of $0.9 million for the years ended December 31, 2013, 2012 and 2011, respectively.

2013 Operating Results

For 2013, we reported net income of $33.1 million compared to net income of $28.3 million in 2012. After deducting preferred stock dividends in 2012, net income available to common shareholders was $33.1 million, or $1.73 per diluted share in 2013, compared to net income available to common shareholders of $25.1 million, or $1.37 per diluted share in 2012.

Income before income tax expense on the Company's Core Bank and Covered assets for the twelve months ended December 31, 2013, 2012 and 2011 were as follows:

(In thousands)	Twelve months ended December 31,
	2013		2012		2011
Income before income tax expense
Core Bank	$	34,621	$	26,495	$	18,936
Covered assets	15,459		16,335		19,289
Total	$	50,080	$	42,830	$	38,225

Income before income tax expense for the Core Bank represents results without direct income and expenses related to Covered assets, as well as an internal estimate of associated asset funding costs. Core Bank pre-tax income grew $8.1 million or 31% in 2013 as compared to 2012 fueled by solid commercial loan growth and declining credit costs. Income from our Covered assets remained relatively stable at $15.5 million, a modest decrease of 5% despite declining balances in our PCI loans. Declining balances in our PCI loans were primarily due to continued early pay-offs of our PCI loans. Income from Covered assets remained relatively stable due to lower charge-offs than generally anticipated.

2013 Significant Transactions

During 2013, we completed the following transactions:

• On January 9, 2013, the Company repurchased the warrants issued to the U.S Treasury as part of the Capital Purchase Program for approximately $1.0 million. After completing the warrant repurchase the Company exited the Capital Purchase Program.

25

• On May 16, 2013, the Company finalized its acquisition of Gorman & Gorman Home Loans. The Company anticipates the acquisition will strengthen its mortgage business. As part of the transaction Gorman and Gorman and legacy Enterprise mortgage operations were combined into a single division named Enterprise Home Loans.

• On August 15, 2013, the Company converted $20.0 million, 9% coupon, trust preferred securities to shares of common stock. As a result of the transaction, the Company reduced its long-term debt by $20.0 million and issued an aggregate of 1.2 million shares of common stock. The Company issued 25,060 shares of additional common stock as inducement for the conversion, which resulted in a $0.4 million, one-time, non-cash expense being recorded.

• On December 6, 2013, the Company completed the sale and closure of four of its branches in the Kansas City region. Two of the branches, as well as $7.6 million of loans and $78.4 million of deposits, as well as $1.5 million of other assets were sold to another financial institution. The Company recorded a pre-tax gain of approximately $1.0 million upon completion of the transaction primarily attributed to a premium on the deposits that were sold.

• On December 30, 2013 the Company prepaid $30.0 million of debt with the FHLB with a weighted average interest rate of 4.09%, and a maturity of 3 years, and incurred a prepayment penalty of $2.6 million before taxes.

Below are highlights of our Banking and Wealth Management segments. For more information on our segments, see Item 8, Note 21 - Segment Reporting.

Banking Segment

• Loans - Loans totaled $2.3 billion at December 31, 2013, including $140.5 million of purchase credit impaired ("PCI") loans (formerly referred to as Portfolio loans covered under FDIC loss share or Covered loans). Portfolio loans excluding PCI loans increased $31.3 million, or 1%, from December 31, 2012. Commercial & Industrial loans increased $78.7 million, or 8%, Consumer and other loans increased $23.9 million or 141%, Construction loans and Residential real estate loans decreased $30.9 million, or 10%, and Commercial Real Estate decreased $40.4 million, or 5%.

PCI loans decreased $60.6 million, or 30%, in 2013, due to loans that paid off, charged-off and principal paydowns. Based on the most recent remeasurement of expected cash flows, the Company expects the average balance of PCI loans to be approximately $108 million, $67 million, and $39 million in 2014, 2015, and 2016, respectively.

• Deposits – Total deposits at December 31, 2013 were $2.5 billion, a decrease of $123.9 million, or 5%, from December 31, 2012 as the Company continued to experience run-off in its interest bearing deposits from lower cost pricing.

Non-interest bearing accounts decreased primarily due to the sale and closure of four branches in our Kansas City market.

Core deposits, which exclude brokered certificates of deposit and include reciprocal CDARS deposits, decreased $168.9 million, or 7%, for 2013 as compared to 2012. Interest bearing transaction accounts including money market accounts decreased $144.0 million, or 10%. Core deposits represented 94% of total deposits at December 31, 2013, compared to 96% at December 31, 2012.

Due to the run-off in other deposit accounts brokered certificates of deposit increased to $139.5 million at December 31, 2013 compared to $94.5 million at December 31, 2012.

• Asset quality – Nonperforming loans, including troubled debt restructurings, were $20.8 million at December 31, 2013, compared to $38.7 million at December 31, 2012. Nonperforming loans represented 0.98% of portfolio loans at December 31, 2013 versus 1.84% at December 31, 2012. Excluding non-accrual loans and PCI loans, there were $0.1 million of portfolio loans that were 30-89 days delinquent at December 31, 2013 as compared to $2.1 million at December 31, 2012.

Provision for portfolio loan losses was a benefit of $0.6 million in 2013, compared to $8.8 million in 2012. The decrease in the provision for loan losses in 2013 was due to lower net chargeoffs, lower levels of criticized loans due to less downgrade activity and lower levels of non-performing loans in 2013 as compared to 2012. See Note 6 – Portfolio Loans and Provision for Loan Losses and Allowance for Loan Losses in this section for more information.

• Net Interest margin – The net interest margin (fully tax equivalent) was 4.78% for 2013, compared to 4.94% for 2012. See Net Interest Income in this section for more information.

• PCI loans and other assets covered under FDIC shared loss agreements - The following table illustrates the net revenue contribution of covered assets for the most recent 3 fiscal years. This presentation excludes the cost of funding the related assets and the operating expenses to service the assets.

Net revenue from PCI loans was $23.4 million for the year ended December 31, 2013 a $4.8 million decrease from December 31, 2012. The decrease in net revenue was primarily due to lower accretion and accelerated cash flows from lower PCI loan balances, as well as a negative impact from the Change in the FDIC loss share receivable due to loan pay offs in which the losses on the loans were less than expected.

27

Wealth Management Segment

Fee income from the Wealth Management segment includes Wealth Management revenue and income from state tax credit brokerage activities. Wealth Management revenue was $7.1 million in 2013, a decrease of $0.2 million, or 2% over 2012. The slight decrease was due to the termination of several less profitable relationships during the year. See Noninterest Income in this section for more information.

RESULTS OF CONTINUING OPERATIONS ANALYSIS

Net Interest Income

Comparison of 2013 and 2012

Net interest income (on a tax equivalent basis) was $137.4 million for 2013 compared to $143.8 million for 2012, a decrease of $6.4 million, or 4%. Total interest income decreased $11.4 million and total interest expense decreased $5.0 million.

Average interest-earning assets decreased $33.8 million, or 1%, to $2.9 billion for the year ended December 31, 2013. Average loans increased $75.9 million, or 3%, to $2.3 billion for the year ended December 31, 2013 from $2.2 billion for the year ended December 31, 2012 primarily due to strong C&I origination in 2013. Average securities and short-term investments decreased $109.7 million, to $603.1 million from 2012 as core deposits declined and portfolio loan volume accelerated slightly. Interest income on earning assets decreased $13.1 million due to lower volumes and increased $1.7 million due to higher rates. The decrease in volume was primarily due to the continued pay-off of PCI loans, offset by higher yields on the remaining balance of related loans. Portfolio loans saw a $7.6 million increase in interest income due to volume, offset by an $8.7 million decrease in interest income due to rates.

For the year ended December 31, 2013, average interest-bearing liabilities decreased $103.5 million, or 4%, to $2.2 billion compared to $2.3 billion for the year ended December 31, 2012. The decrease in average interest-bearing liabilities resulted from a $190.3 million decrease in average interest-bearing deposits. This decrease resulted from a $96.7 million decline in certificates of deposits, $68.4 million decline in average money market accounts and savings accounts, and a decrease of $25.2 million in interest-bearing transaction accounts. The significant decrease in certificates of deposits and money market and saving accounts was due to the Company's continued initiative to lower its cost of funds as well as continued historically low rates deterring clients from deposit accounts. For the year ended December 31, 2013, interest expense on interest-bearing liabilities decreased $4.3 million due to declining rates and $0.8 million due to the impact of lower volumes, versus the same period in 2012.

For the year ended December 31, 2013, the tax-equivalent net interest margin was 4.78%, compared to 4.94% in the same period of 2012. The decrease in margin was primarily due to lower yields on newly originated portfolio loans, the pay-off of higher-yielding PCI loans lessening their impact on the overall margin, offset by reduced rates on interest-bearing liabilities due to continued low interest rates, as well as the conversion of $20 million of our trust preferred securities with a 9% coupon rate to common equity.

The Core net interest margin, defined as Net interest margin (fully tax equivalent), including contractual interest on PCI loans, but excluding the incremental accretion on these loans, for the years ended December 31, 2013 and 2012 is as follows:

	Twelve months ended December 31,
	2013		2012
Core net interest margin	3.55	%	3.57	%

The Core net interest margin decline in 2013 from 2012 was due to lower loan yields partially offset by an improved earning asset mix and lower deposit and overall funding costs. The Company believes the Core net interest margin is an important measure of our financial performance even though it is a non-GAAP measure. Included in this MD&A under the caption "Use of Non-GAAP Financial Measures" is a reconciliation of net interest margin to Core net interest margin. The Average Balance Sheet and Rate/Volume sections following contain additional information regarding our net interest income.

Comparison of 2012 and 2011

Net interest income (on a tax equivalent basis) was $143.8 million for 2012 compared to $114.0 million for 2011, an increase of $29.8 million, or 26%. Total interest income increased $22.8 million and total interest expense decreased $7.0 million.

Average interest-earning assets increased $143.3 million, or 5%, to $2.9 billion for the year ended December 31, 2012 from $2.8 billion for the year ended December 31, 2011. Average loans increased $144.9 million, or 7%, to $2.2 billion for the year ended December 31, 2012 from $2.1 billion for the year ended December 31, 2011. Average securities and short-term investments remained relatively flat decreasing only $1.6 million, to $712.7 million from 2011 as core deposit growth was consistent with loan demand. Interest income on earning assets increased $10.9 million due to higher volumes and $11.9 million due primarily to higher yields on PCI loans during 2012 for a total increase of $22.8 million in interest income from 2011.

For the year ended December 31, 2012, average interest-bearing liabilities decreased $36.4 million, or 2%, to $2.3 billion compared to $2.4 billion for the year ended December 31, 2011. The decrease in average interest-bearing liabilities resulted from a $54.5 million decrease in average interest-bearing deposits. This decrease resulted from a decrease of $171.8 million in certificates of deposits, which was partially offset by a $72.4 million increase in average money market accounts and savings accounts, and an increase of $44.9 million in interest-bearing transaction accounts. The significant decrease in certificates of deposits was due to an initiative by the Company to lower its cost of funds. For the year ended December 31, 2012, interest expense on interest-bearing liabilities decreased $5.4 million due to declining rates and $1.6 million due to the impact of lower volumes, for a total decrease of $7.0 million versus the same period in 2011.

For the year ended December 31, 2012, the tax-equivalent net interest rate margin was 4.94%, compared to 4.12% in the same period of 2011. The increase in the margin was primarily due to better earning asset mix, higher yields on Covered assets, and lower funding costs. For the year ended December 31, 2012, the Core net interest margin increased to 3.57% as compared to 3.49% for 2011 due to improvement in our earning asset mix and lower funding costs. These factors were partially offset by declines in our earning asset yields. The Core net interest margin includes the contractual interest on PCI loans, but excludes the incremental accretion income on these loans. The Company believes the Core net interest margin is an important measure of our financial performance even though it is a non-GAAP measure. Included in this MD&A is a reconciliation of net interest margin to Core net interest margin. The Average Balance Sheet and Rate/ Volume sections following contain additional information regarding our net interest income.

The Core net interest margin, defined as Net interest margin (fully tax equivalent), including contractual interest on PCI loans, but excluding the incremental accretion on these loans, for the years ended December 31, 2012 and 2011 is as follows:

	Twelve months ended December 31,

Provision for loan losses.

The provision for loan losses excluding PCI loans was a benefit of $0.6 million for 2013 compared to expense of $8.8 million for 2012 and $13.3 million for 2011. The lower provision for loan losses for 2013 compared to 2012 and 2011 was due to lower levels of loan risk rating downgrades, lower levels of non-performing loans, and significantly lower net charge-offs incurred during the year.

For PCI loans, the Company remeasures contractual and expected cash flows on a quarterly basis. When the remeasurement process results in an increase in expected losses, impairment is recorded through provision for loan losses. As a result of this impairment, the FDIC loss share receivable is increased to reflect anticipated future cash to be received from the FDIC. The amount of the increase is determined based on the specific loss share agreement, but is generally 80% of the losses. Changes in the FDIC loss share receivable are recorded in noninterest income. The provision for loan losses on PCI loans was $5.0 million for 2013 compared to $14.0 million in 2012.

Total noninterest income	$	9,899		$	9,084		$	18,508		$	815		$	(9,424	)

Comparison of 2013 and 2012

Noninterest income increased $0.8 million, or 9%, in 2013 compared to 2012. The increase is primarily due to the gain recorded on the sale of branches in our Kansas City market, as well as increased service charges on deposit accounts, and gains on other real estate, offset by decreases in income related to changes in the FDIC loss share receivable.

• Wealth Management revenue– For the year ended December 31, 2013, Wealth Management revenue decreased $0.2 million, or 2%, compared to 2012. Assets under administration were $1.4 billion at December 31, 2013, a 20% decrease from December 31, 2012. Assets under management were $830 million at December 31, 2013, a 3% decrease from December 31, 2012. The decrease in Wealth Management revenue and assets under management was primarily due to the termination of several less profitable relationships during the year. The decline in assets under administration was due to the loss of a large custody relationship in the fourth quarter of 2013.

• Service charges and other fee income– For the year ended December 31, 2013, service charges and other fee income increased $1.4 million compared to 2012 due to an increase in service charges on business accounts, as well as higher sales of treasury management services, including better pricing and reductions in the amount of fees waived.

• Gain on sale of branches - For the year ended December 31, 2013 the Company sold two of its Kansas City branches to another financial institution. As part of the transaction the Company recorded a gain of $1.0 million upon completion of the transaction primarily attributable to a premium on the deposits that were sold.

• Sale of other real estate – For the year ended December 31, 2013, we sold $22.4 million of other real estate for a gain of $3.4 million which included a gain of $2.3 million from other real estate not covered by loss share agreements and a gain of $1.1 million from other real estate covered by loss share agreements. In 2012, we sold $48.8 million of other real estate for a net gain of $2.2 million, which included a gain of $0.1 million from other real estate not covered by loss share agreements and a gain of $2.1 million from other real estate covered by loss share agreements.

• State tax credit activity, net– For the year ended December 31, 2013, the Company recorded a gain of $2.5 million compared to a gain of $2.2 million in 2012. The increase is due to the timing of client purchases of the state tax credits in 2013 as compared to 2012, slightly offset by a mark to market loss for our tax credits carried

33

at fair value. Refer to Item 8 -Note 20 -Fair Value Measurements for additional information on the fair value of State tax credits.

• Sale of securities – During 2013, the Company realized $160 million of proceeds on the sale of investment securities, generating a net gain of $1.3 million. This compared to 2012 amounts of $111 million of proceeds, and a net gain of $1.2 million.

• Change in FDIC loss share receivable – Income related to changes in the FDIC loss share receivable reduced noninterest income by $18.2 million in 2013 compared to $14.9 million in 2012. The decrease in income related to the FDIC loss share receivable was primarily due to amortization expense and loan pay-offs in which the losses on the loans were less than expected. This was offset with an increase in income due to the impact of provision expense. See Item 8 - Note 7 for more information on the FDIC loss share receivable.

• Miscellaneous income – For the year ended December 31, 2013, Miscellaneous income increased $0.3 million, or 10%. The increase in Miscellaneous income is primarily due to income earned on an additional $20 million of bank owned life insurance ("BOLI") policy purchased in the second quarter of 2013.

Comparison of 2012 and 2011

Noninterest income decreased $9.4 million, or 51%, in 2012 compared to 2011. The decrease is primarily due to decreases in income related to changes in the FDIC loss share receivable partially offset by increased amounts across most other noninterest income accounts.

• Wealth Management revenue– For the year ended December 31, 2012, Wealth Management revenue from the Trust division increased $0.5 million, or 7%, compared to 2011. The increase in Wealth Management revenue was primarily due to increased investment advisory revenue. Assets under administration were $1.8 billion at December 31, 2012, a 13% increase from December 31, 2011 due to market value increases and additional accounts from new and existing clients.

• Service charges and other fee income–For the year ended December 31, 2012, service charges and other fee income increased $1.4 million compared to 2011 due to an increase in service charges on business accounts, debit card and credit card income, and overdraft fees, primarily due to the acquisition of FNBO.

• Sale of other real estate – For the year ended December 31, 2012, we sold $48.8 million of other real estate for a gain of $2.2 million which included a gain of $0.1 million from other real estate not covered by loss share agreements and a gain of $2.1 million from other real estate covered by loss share agreements. In 2011, we sold $13.1 million of other real estate for a net gain of $0.9 million.

• State tax credit activity, net– For the year ended December 31, 2012, the Company recorded a gain of $2.2 million compared to a gain of $3.6 million in 2011. The decrease is due to the timing of client purchases of the state tax credits in 2012 as compared to 2011, as well as a reduction in the gain on the fair value of tax credits. For more information on the fair value treatment of the state tax credits, see Note 20 – Fair Value Measurements.

• Sale of securities – During 2012, the Company realized approximately $110.9 million of proceeds on the sale of investment securities, generating a net gain of $1.2 million. This compared to 2011 amounts of approximately $84.5 million of proceeds, and a net gain of $1.5 million.

• Change in FDIC loss share receivable– Income related to changes in the FDIC loss share receivable reduced noninterest income by $14.9 million in 2012 compared to $3.5 million in 2011. The decrease in income related to the FDIC loss share receivable was primarily due to amortization expense and loan pay offs in which the losses on the loans were less than expected offset with an increase in income due to the impact of provision expense.

• Miscellaneous income– For the year ended December 31, 2012, Miscellaneous income rose $0.5 million, or 19%. The increase in Miscellaneous income is due to an increase in fees related to client swap transactions, as well as increased gains on the sale of mortgages.

Comparison of 2013 and 2012

Noninterest expenses increased $4.9 million or 6% in 2013. The Company's efficiency ratio, which measures noninterest expense as a percentage of total revenue, for 2013 was 62.5% compared to 56.7% for 2012.

Employee compensation and benefits. Employee compensation and benefits increased $3.8 million, or 9%, over 2012. Employee compensation and benefits increased primarily due to higher variable and long-term incentive compensation from the Company's continued improved financial performance.

All other expense categories. All other expense categories increased $1.1 million, or 1%, over 2012. Significantly lower loan, legal and other real estate expenses and professional fees from improved credit quality, timing of reimbursements from the FDIC loss share arrangements, and the resolution of two significant legal cases were offset by the $2.6 million prepayment penalty on the redemption of $30.0 million of debt with the FHLB.

The Company expects noninterest expenses to be between $20 million and $22 million per quarter in 2014.

Comparison of 2012 and 2011

Noninterest expenses increased $8.9 million, or 12% in 2012. The Company's efficiency ratio, which measures noninterest expense as a percentage of total revenue, for 2012 was 56.7% compared to 58.6% for 2011.

Employee compensation and benefits. Employee compensation and benefits increased $6.7 million, or 18%, over 2011. Employee compensation and benefits increased due to a full year of salaries of FNBO employees, increased headcount in functions to support our growth, and higher variable compensation accruals.

All other expense categories. All other expense categories increased $2.3 million, or 6%, over 2011. Higher professional, legal and consulting expenses, amortization of intangibles, and miscellaneous expenses were offset by lower loan, legal and other real estate and FDIC and other insurance expenses. The remaining categories were relatively flat when compared to 2011 amounts.

Higher professional, legal and consulting fees were primarily due to the restatement of our financial statements in 2012, as well as continued ongoing litigation defense costs. Higher amortization of intangibles is due to a full year of amortization of customer deposit intangibles associated with the FNBO acquisition. Increased other expenses are due to a variety of items, including higher accruals and included the $575,000 clawback liability recorded for estimated reimbursements to the FDIC at the end of our loss share agreements.

35

Lower loan, legal and other real estate expenses are primarily due to decreased other real estate balances which reduces expenses for utilities, legal fees, property taxes, and insurance. These amounts decreased by $1.2 million when compared to 2011. Further, write-downs in valuation of other real estate were $2.3 million lower when compared to 2011. FDIC and other insurance expenses are lower in 2012 primarily due to a reduction in FDIC premiums of approximately $662,000.

Income Taxes

In 2013, the Company recorded income tax expense of $17.0 million on pre-tax income of $50.1 million, resulting in an effective tax rate of 33.9%. The Company's effective tax rate was consistent with 2012, even with higher pre-tax income in 2013. This was due to changes in tax rates between years from benefits in state apportionment factors. The following items were included in Income tax expense and impacted the 2013 effective tax rate:

• interest income on tax exempt mortgages and municipal bonds of $1.2 million.

• decrease in the tax rate used for deferred tax assets of $0.3 million.

In 2012, the Company recorded income tax expense of $14.5 million on pre-tax income of $42.8 million, resulting in an effective tax rate of 33.9%. The following items were included in Income tax expense and impacted the 2012 effective tax rate:

• interest income on tax exempt mortgages and municipal bonds of $0.9 million.

• reversal of a $0.3 million state deferred tax asset valuation allowance

In 2011, the Company recorded income tax expense of $12.8 million on pre-tax income of $38.2 million, resulting in an effective tax rate of 33.5%. The following items were included in Income tax expense and impacted the 2011 effective tax rate:

• the expiration of the statute of limitations for the 2007 tax year warranted the release of $0.3 million of reserves related to certain state tax positions;

FINANCIAL CONDITION

Comparison for December 31, 2013 and 2012

Total assets at December 31, 2013 were $3.2 billion compared to $3.3 billion at December 31, 2012, a decrease of 155.6 million, or 5%. During 2013, we intentionally reduced higher interest bearing deposits, and paid off higher interest bearing debt to lower our cost of funding. This was accomplished by reducing our investment portfolio and funding Portfolio Loan growth through pay-offs in our PCI loan book.

At December 31, 2013, Portfolio Loans totaled $2.1 billion, an increase of $31.3 million, or 1% from December 31, 2012. At December 31, 2013, PCI loans totaled $140.5 million, a decrease of $60.6 million, or 30%.

Securities available for sale were $434.6 million at December 31, 2013 compared to $640.2 million at December 31, 2012. As noted above, sales in our securities available for sale were utilized to fund the run-off in our interest-bearing deposits and pay for the $30.0 million of FHLB advances redeemed. It also allowed us to improve the mix of interest earning assets toward higher yielding loans.

At December 31, 2013, Other assets included $45.3 million of bank-owned life insurance and $39.4 million of deferred tax assets.

At December 31, 2013, deposits were $2.5 billion, a decrease of $123.9 million, or 5%, from $2.7 billion at December 31, 2012. The decrease in deposits was largely comprised of our money market and savings accounts, as well as our interest bearing transaction accounts as clients continue to move away from these products due to their historically low rates.

The Company significantly reduced its long-term debt by prepaying $30.0 million of its FHLB advances, converting $20.0 million of its trust preferred securities in EFSC Capital Trust VIII to common stock, and paying off a $2.5 million subordinated note with a 10% interest rate during 2013.

Other borrowings primarily consist of customer repurchase agreements and were $214.3 million at December 31, 2013, a $30.7 million or 13% decrease from December 31, 2012. The decrease was primarily due to the sale of certain customer repurchase accounts associated with our branch sales and closures in our Kansas City market.

Portfolio Loans

Portfolio loans (defined as all loans other than PCI loans) net of unearned loan fees and costs, increased $31.3 million, or 1%, during 2013. Commercial & Industrial loans increased $78.7 million, or 8%, during the year and represent 49% of the loan portfolio at December 31, 2013. The Company's lending strategy emphasizes commercial and industrial and commercial real estate loans to small and medium sized businesses and their owners in the St. Louis, Kansas City and Phoenix metropolitan markets.

A common underwriting policy is employed throughout the Company. Lending to small and medium sized businesses is riskier from a credit perspective than lending to larger companies, but the risk is appropriately considered with higher loan pricing and ancillary income from cash management activities. As additional risk mitigation, the Company will generally hold only $15 million or less of aggregate credit exposure (both direct and indirect) with one borrower, in spite of a legal lending limit of over $91 million. There are seven borrowing relationships where we have committed more than $10.0 million with the largest being a $15.0 million line of credit with minimal usage. For the $2.1 billion loan portfolio, the Company's average loan relationship size was just under $950,000, and the average note size is approximately $625,000.

The Company also buys and sells loan participations with other banks to help manage its credit concentration risk. At December 31, 2013, the Company had purchased loan participations of $176.2 million ($108.1 million outstanding) and had sold loan participations of $424.5 million ($357.9 million outstanding). Approximately 76 borrowers make up the participations purchased, with an average outstanding loan balance of $1.4 million. Twelve relationships, or $66.5 million of the $108.1 million in participations purchased, met the definition of a “Shared National Credit.” None of the relationships were considered out of our markets.

Commercial and industrial loans are made based on the borrower's character, experience, general credit strength, and ability to generate cash flows for repayment from income sources, even though such loans may also be secured by real estate or other assets. The credit risk related to commercial loans is largely influenced by general economic conditions and the resulting impact on a borrower's operations. Commercial and industrial loans are primarily made to borrowers operating within the manufacturing industry.

Real estate loans are also based on the borrower's character, but more emphasis is placed on the estimated collateral values.

Approximately $316.6 million, or 41%, of the commercial real estate loans were owner-occupied by commercial and industrial businesses where the primary source of repayment is dependent on sources other than the underlying collateral. Multifamily properties and other commercial properties on which income from the property is the primary source of repayment represent the balance of this category. The majority of this category of loans is secured by commercial and multi-family properties located within our St. Louis and Kansas City markets. These loans are underwritten based on the cash flow coverage of the property, typically meet the Company's loan to value guidelines, and generally require either the limited or full guaranty of principal sponsors of the credit.

Real estate construction loans, relating to residential and commercial properties, represent financing secured by raw ground or real estate under development for eventual sale. Approximately $27.9 million of these loans include the use of interest reserves and follow standard underwriting guidelines. Construction projects are monitored by the officer and a centralized independent loan disbursement function is employed.

38

Residential real estate loans include residential mortgages, which are loans that, due to size, do not qualify for conventional home mortgages that the Company sells into the secondary market, second mortgages and home equity lines. Residential mortgage loans are usually limited to a maximum of 80% of collateral value.

Consumer and other loans mainly represent loans to individuals on both a secured and unsecured basis. Credit risk is managed by thoroughly reviewing the creditworthiness of the borrowers prior to origination.

The following descriptions focus on the Portfolio loans and exclude PCI loans.

The Construction and Land Development category represents $117.0 million, or 5%, of the total loan portfolio. Within that category, there was $6.9 million of loans secured by raw ground, $69.1 million of commercial construction, and $41.0 million of residential construction.

The Commercial construction component of the portfolio consisted of approximately 23 loan relationships with an average outstanding loan balance of $2.2 million. The largest loans were a $9.1 million line of credit and an $8.0 million term loan both secured by commercially zoned land in St. Louis.

The Residential construction component of the portfolio consisted of single family housing development properties primarily in our St. Louis and Kansas City markets. There were approximately 56 loan relationships in this category with an average outstanding loan balance of $0.5 million. The largest loans were a $2.9 million loan secured by a

40

residential development in the Kansas City market, and a $2.4 line of credit secured by a residential development in the St. Louis market.

The largest segments of the non-owner occupied components of the commercial real estate portfolio are retail and commercial office permanent loans.

At December 31, 2013, the Company had $89.0 million of non-owner occupied permanent loans secured by retail properties. There were approximately 43 loan relationships in this category with an average outstanding loan balance of $2.1 million. The largest loans outstanding at year-end were a $8.5 million loan secured by a hotel in St. Louis, a $7.0 million loan secured by various retail properties in Kansas City, and a $6.5 million loan secured by a hotel in Arizona.

At December 31, 2013, the Company had $141.1 million of non-owner occupied permanent loans secured by commercial office properties. There were approximately 53 loan relationships with an average outstanding loan balance of $2.0 million. The largest loans outstanding at year end were an $8.3 million loan secured by a single tenant office building in Kansas City, a $7.5 million loan secured by a medical office building in the St. Louis region, and a $7.0 million loan secured by a multi-tenant office building in St. Louis city.

Factors that are critical to managing overall credit quality are sound loan underwriting and administration, systematic monitoring of existing loans and commitments, early identification of potential problems, an adequate allowance for loan losses, and sound non-accrual and charge-off policies.

Significant loan concentrations are considered to exist for a financial institution when there are amounts loaned to numerous borrowers engaged in similar activities that would cause them to be similarly impacted by economic or other conditions. At December 31, 2013, no significant concentrations exceeding 10% of total loans existed in the Company's loan portfolio, except as described above.

(1) Loan balances are net of unearned loan and costs.

(2) Not adjusted for impact of interest rate swap agreements.

Fixed rate loans comprise approximately 39% of the loan portfolio at December 31, 2013. Variable rate loans are based on the prime rate or the London Interbank Offered Rate (“LIBOR”). The Bank's “prime rate” has been 4.00% since late 2008 when the Federal Reserve lowered the targeted Fed Funds rate to 0.25%. Some of the variable rate loans also use the “Wall Street Journal Prime Rate” which has been 3.25% since late 2008. Most loan originations have one to three year maturities. While the loan relationship has a much longer life, the shorter maturities allow the Company to revisit the underwriting and pricing on each relationship periodically. Management monitors this mix as part of its interest rate risk management. See Interest Rate Risk section.

Of the $172.2 million of commercial real estate loans maturing in one year or less, $120.6 million, or 70%, represents loans secured by non-owner occupied commercial properties.

Nonperforming assets

Nonperforming loans are defined as loans on non-accrual status, generally loans 90 days or more past due but still accruing, and restructured loans that are still accruing interest or in a non-accrual status. Restructured loans involve the granting of a concession to a borrower experiencing financial difficulty involving the modification of terms of the loan, such as changes in payment schedule or interest rate. Nonperforming assets include nonperforming loans plus foreclosed real estate.

Nonperforming loans exclude credit-impaired loans acquired in FDIC-assisted transactions. These PCI loans are accounted for on a pool basis, and the pools are considered to be performing. See Item 8, Note 7 - Purchase Credit Impaired Loans for more information on these loans.

Loans are generally placed on non-accrual status when contractually past due 90 days or more as to interest or principal payments. Additionally, whenever management becomes aware of facts or circumstances that may adversely impact the collectability of principal or interest on loans, it is management's practice to place such loans on non-accrual status immediately, rather than delaying such action until the loans become 90 days past due. Previously accrued and uncollected interest on such loans is reversed. Income is recorded only to the extent that a determination has been made that the principal balance of the loan is collectable and the interest payments are subsequently received in cash, or for a restructured loan, the borrower has made six consecutive contractual payments. If collectability of the principal is in doubt, payments received are applied to loan principal.

Loans past due 90 days or more but still accruing interest are also generally included in nonperforming loans. Loans past due 90 days or more but still accruing are classified as such where the underlying loans are both well secured (the collateral value is sufficient to cover principal and accrued interest) and are in the process of collection. At December 31, 2013, we did not have any loans past due greater than 90 days and not included in nonperforming loans.

The Company's nonperforming loans meet the definition of “impaired loans” in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). As of December 31, 2013, 2012, and 2011, the Company had 20, 40, and 41 impaired loan relationships, respectively.

Investments

At December 31, 2013, our portfolio of Securities available for sale was $434.6 million or 14% of total assets. This portfolio is primarily comprised of agency mortgage-backed securities and obligations of U.S. Government- sponsored enterprises.

Our Other investments, at cost, primarily consist of the FHLB capital stock, common stock investments related to our trust preferred securities and other private equity investments. At December 31, 2013, of the $6.7 million in FHLB capital stock, $4.0 million is required for FHLB membership and $2.0 million is required to support our outstanding advances. Historically, it has been the FHLB's practice to automatically repurchase activity-based stock that became excess because of a member's reduction in advances. The FHLB has the discretion, but is not required, to repurchase any shares that a member is not required to hold.

The table below sets forth the carrying value of investment securities held by the Company at the dates indicated:

Yields on tax-exempt securities are computed on a taxable equivalent basis using a tax rate of 39%. Expected maturities will differ from contractual maturities, as borrowers may have the right to call or repay obligations with or without prepayment penalties.

FDIC Loss Share Receivable

Our four loss share agreements with the FDIC have provisions by which the FDIC is required to reimburse us for certain loan losses including up to 90 days of accrued but unpaid interest and direct expenses related to the resolution of assets incurring a loss. Generally, the agreements carry terms of five years from date of acquisition for non-single family or commercial assets and ten years from date of acquisition for single family assets. The loss share agreements with the FDIC for the Home National Bank and Legacy bank acquisitions contain 80% loss coverage during the term of the agreements while the Valley Capital agreement now provides for 95% loss coverage through the remaining term of the agreement. The shared loss agreement relative to our FNBO acquisition has three tranches of losses, each with a specified loss coverage percentage. Losses up to $112.6 million are reimbursed 80% by the FDIC. Losses from $112.6 million to $148.9 million will not be reimbursed, while losses in excess of $148.9 million revert to 80% loss share reimbursement.

Projections of future losses and the timing thereof are inherently uncertain, though we do not expect to move into the 2^nd tranche of losses in the FNBO agreement in the next twelve months. The Change in FDIC loss share receivable represents the amortization and other changes necessary to adjust the value of our FDIC loss share receivable to the estimated recoveries from the FDIC subject to the aforementioned contractual limitations of the loss sharing agreements.

Loss Share Expiration Summary

The following table presents a summary of the expiration dates of our loss share coverage under our FDIC agreements, along with the Covered Asset balances per bank at December 31, 2013:

(in thousands)	Expiration Date		Covered Assets

FNBO	August 2016	August 2021	51,665		8,554
			$	99,960	$	22,560

*NSF represents non-single family loans covered under FDIC loss share arrangements.

**SF represents single family loans covered under FDIC loss share arrangements.

As of December 31, 2013, $2.6 million of the Company's PCI loans acquired in its FDIC assisted acquisitions were not covered under loss sharing agreements. The Company has an estimated $53.5 million of accretable yield and $87.4 million of non-accretable difference remaining on loans acquired in FDIC assisted acquisitions as of December 31, 2013.

	$	2,453,475	0.45	%	$	2,656,528	0.58	%	$	2,578,444	0.84	%

The Bank continued to lower its cost of deposits in 2013 including an improvement in its overall mix by lowering its certificates of deposits. The year over year decrease in average deposits was seen in all areas except Saving accounts and was due to the Company's overall initiative to lower its cost of funds. As deposit rates continued to decline, the Bank positioned its pricing strategy to favor adjustable rate transaction accounts over longer term time deposits. The result was to lower the percentage of time deposits and better position the bank for a prolonged low rate cycle.

Brokered certificates of deposits at December 31, 2013 were $139.5 million, or 6%, of total deposits compared to $94.5 million, or 4%, at December 31, 2012. Noninterest-bearing demand deposits represented 26% of total deposits at December 31, 2013 and 2012. Maturities of certificates of deposit of $100,000 or more were as follows as of December 31, 2013:

(in thousands)	Total
Three months or less	$	58,653
Over three through six months	92,685

Liquidity and Capital Resources

Liquidity

The objective of liquidity management is to ensure we have the ability to generate sufficient cash or cash equivalents in a timely and cost-effective manner to meet our commitments as they become due. Typical demands on liquidity are run-off from demand deposits, maturing time deposits which are not renewed, and fundings under credit commitments to customers. Funds are available from a number of sources, such as from the core deposit base and from loans and securities repayments and maturities.

Additionally, liquidity is provided from sales of the securities portfolio, fed fund lines with correspondent banks, the Federal Reserve and the FHLB, the ability to acquire large and brokered deposits, and the ability to sell loan participations to other banks. These alternatives are an important part of our liquidity plan and provide flexibility and efficient execution of the asset-liability management strategy.

Our Asset-Liability Management Committee oversees our liquidity position, the parameters of which are approved by the Bank's Board of Directors.Our liquidity position is monitored monthly by producing a liquidity report, which measures the amount of liquid versus non-liquid assets and liabilities. Ourliquidity management framework includes

50

measurement of several key elements, such as the loan to deposit ratio, a liquidity ratio, and a dependency ratio. The Company's liquidity framework also incorporates contingency planning to assess the nature and volatility of funding sources and to determine alternatives to these sources. While core deposits and loan and investment repayments are principal sources of liquidity, funding diversification is another key element of liquidity management and is achieved by strategically varying depositor types, terms, funding markets, and instruments.

For the year ended December 31, 2013, net cash provided by operating activities was $8.1 million less than 2012. The decrease in cash was primarily due to higher non-cash operating expenses in 2012. Net cash provided in investing activities was $176.1 million in 2013 versus net cash used of $6.3 million for 2012. The significant increase in 2013 was due to proceeds from investment sales, as well as an overall decrease in loan balances in 2013. This was offset by the $67.5 million net cash paid related to the sale and closure of 4 branches in the Company's Kansas City market. Net cash used in financing activities was $111.2 million in 2013, versus $102.9 million in 2012. The change in cash provided by financing activities was primarily due to increased pay downs of our FHLB advances and other borrowings, offset by less contraction in our interest-bearing deposit accounts as well as the TARP repurchase in 2012.

Strong capital ratios, credit quality and core earnings are essential to retaining cost-effective access to the wholesale funding markets. Deterioration in any of these factors could have a negative impact on the Company's ability to access these funding sources and, as a result, these factors are monitored on an ongoing basis as part of the liquidity management process. The Bank is subject to regulations and, among other things, may be limited in its ability to pay dividends or transfer funds to the parent company. Accordingly, consolidated cash flows as presented in the consolidated statements of cash flows may not represent cash immediately available for the payment of cash dividends to the Company's shareholders or for other cash needs.

Parent Company liquidity

The parent company's liquidity is managed to provide the funds necessary to pay dividends to shareholders, service debt, invest in subsidiaries as necessary, and satisfy other operating requirements. The parent company's primary funding sources to meet its liquidity requirements are dividends and payments from the Bank and proceeds from the issuance of equity (i.e. stock option exercises, stock offerings). Another source of funding for the parent company includes the issuance of subordinated debentures and other debt instruments.

On November 6, 2012, the parent company entered into a $12.0 million unsecured term loan agreement ("Term Loan") with another bank with the proceeds being used to redeem the Company's preferred stock held by the U.S. Treasury. The loan has a maturity date of November 6, 2015 and will be repaid in quarterly installments of $300,000, with a balloon payment at maturity. As of December 31, 2013 and 2012 the Company had $10.5 million and $11.7 million, respectively, outstanding on the Term Loan. The Term Loan pays interest based on LIBOR plus a spread determined by the Company's outstanding balance under the Term Loan. The Term Loan is subject to ongoing compliance with a number of customary affirmative and negative covenants as well as specified financial covenants. The Company believes it was in compliance with all relevant covenants under the Term Loan at December 31, 2013.

Periodically, management of the Bank will provide a dividend to supplement the parent company's liquidity. This included a $10.0 million in the fourth quarter of 2013 and a $15.0 million dividend during the fourth quarter of 2012. The 2012 dividend was ultimately used to repurchase the Series A Preferred from the U.S. Treasury. Management currently believes the current level of cash at the holding company of approximately $16.0 million will be sufficient to meet all projected cash needs for at least the next year.

As of December 31, 2013, the Company had $62.6 million of outstanding subordinated debentures as part of nine Trust Preferred Securities Pools. These securities are classified as debt but are included in regulatory capital and the related interest expense is tax-deductible, which makes them an attractive source of funding. On August 15, 2013, the Company converted $20.0 million, 9% coupon, trust preferred securities from EFSC Capital Trust VIII to common stock at the election of one of the holders. As a result of the transaction the Company reduced its long-term debt by $20.0 million and issued an aggregate of 1.2 million shares of common stock. The Company issued 25,060 shares of additional common stock as inducement for the holder's election. The inducement resulted in a $0.4 million, one-time, non-cash expense recorded in Other noninterest expense during the third quarter of 2013.

51

Regulations recently finalized by the Federal Reserve Board to implement the Basel III regulatory capital reforms allow our currently outstanding trust preferred securities to retain Tier 1 capital status.

On January 9, 2013, the Company repurchased warrants issued by the U.S. Treasury as part of the Capital Purchase Program. The repurchase price was approximately $1.0 million.

Bank liquidity

The Bank has a variety of funding sources available to increase financial flexibility. In addition to amounts currently borrowed, at December 31, 2013, the Bank could borrow an additional $235.5 million from the FHLB of Des Moines under blanket loan pledges and has an additional $607.0 million available from the Federal Reserve Bank under a pledged loan agreement. The Bank has unsecured federal funds lines with four correspondent banks totaling $45.0 million. On December 30, 2013, the Company prepaid $30.0 million of debt with the Federal Home Loan Bank with a weighted average interest rate of 4.09% and a maturity of 3 years and incurred a prepayment penalty of $2.6 million. These transactions are expected to further reduce our cost of interest bearing liabilities in future periods and will help mitigate net interest margin compression.

Investment securities are another important tool to the Bank's liquidity objectives. Of the $434.6 million of the securities available for sale at December 31, 2013, $270.1 million was pledged as collateral for deposits of public institutions, treasury, loan notes, and other requirements. The remaining $164.5 million could be pledged or sold to enhance liquidity, if necessary.

In the normal course of business, the Bank enters into certain forms of off-balance sheet transactions, including unfunded loan commitments and letters of credit. These transactions are managed through the Bank's various risk management processes. Management considers both on-balance sheet and off-balance sheet transactions in its evaluation of the Company's liquidity. The Bank has $848.8 million in unused commitments as of December 31, 2013. While this commitment level would exhaust the majority the Company's current liquidity resources, the nature of these commitments is such that the likelihood of funding them in the aggregate at any one time is low.

Capital Resources

The Company and the Bank are subject to various regulatory capital requirements administered by the Federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and its bank affiliate must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The banking affiliate’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors.

Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth in the following table) of total and Tier 1 capital to risk-weighted assets, and of Tier 1 capital to average assets. To be categorized as “well capitalized”, banks must maintain minimum total risk-based (10%), Tier 1 risk-based (6%) and Tier 1 leverage ratios (5%). As of December 31, 2013, and December 31, 2012, the Company and the Bank met all capital adequacy requirements to which they are subject.

The Bank continues to exceed regulatory standards and met the definition of “well-capitalized” (the highest category) at December 31, 2013, 2012, and 2011. Refer to Item 8 - Note 16 Regulatory Matters for a summary of our risk-based capital and leverage ratios.

The Company's tangible common equity ratio was 7.78% at December 31, 2013 compared to 6.02% and 4.99% at December 31, 2012 and 2011, respectively. The Company's Tier 1 common equity ratio was 10.08% at December 31, 2013 compared to 7.70% and 7.32% at December 31, 2012 and 2011. The significant increase in tangible common

52

equity and Tier 1 common equity ratios as compared to the prior year periods is due to an increase in capital from net income and the conversion of $20 million of trust preferred securities to common equity.

The Company believes the tangible common equity and Tier 1 common equity rations are important measures of capital strength even though they are considered to be non-GAAP measures. The tables further within MD&A reconcile these ratios to U.S. GAAP.

Risk Management

Market risk arises from exposure to changes in interest rates and other relevant market rate or price risk. The Company faces market risk in the form of interest rate risk through transactions other than trading activities. Market risk from these activities, in the form of interest rate risk, is measured and managed through a number of methods. The Company uses financial modeling techniques to measure interest rate risk. These techniques measure the sensitivity of future earnings due to changing interest rate environments. Guidelines established by the Bank's Asset/Liability Management Committee and approved by the Bank's Board of Directors are used to monitor exposure of earnings at risk. General interest rate movements are used to develop sensitivity as the Company feels it has no primary exposure to a specific point on the yield curve. These limits are based on the Company's exposure to immediate and sustained parallel rate movements up to 400 basis points, either upward or downward.

53

Interest Rate Risk

Our interest rate sensitivity management seeks to avoid fluctuating interest margins to provide for consistent growth of net interest income through periods of changing interest rates. Interest rate sensitivity varies with different types of interest-earning assets and interest-bearing liabilities. We attempt to maintain interest-earning assets, comprised primarily of both loans and investments, and interest-bearing liabilities, comprised primarily of deposits, maturing or repricing in similar time horizons in order to minimize or eliminate any impact from market interest rate changes. In order to measure earnings sensitivity to changing rates, the Company uses an earnings simulation model.

The Company determines the sensitivity of its short-term future earnings to a hypothetical plus or minus 100 to 400 basis point parallel rate shock through the use of simulation modeling. The simulation of earnings includes the modeling of the balance sheet as an ongoing entity. Future business assumptions involving administered rate products, prepayments for future rate-sensitive balances, and the reinvestment of maturing assets and liabilities are included. These items are then modeled to project net interest income based on a hypothetical change in interest rates. The resulting net interest income for the next 12-month period is compared to the net interest income amount calculated using flat rates. This difference represents the Company's earnings sensitivity to a plus or minus 100 basis points parallel rate shock.

The following table summarizes the expected impact of interest rate shocks on net interest income (due to the current level of interest rates, the 200 and 300 basis point downward shock scenarios are not shown):

Rate Shock	Annual % change in net interest income
+ 300 bp	+ 10.0%
+ 200 bp	+ 6.4%
+ 100 bp	+ 2.7%
- 100 bp	- 1.3%

The Company occasionally uses interest rate derivative financial instruments as an asset/liability management tool to hedge mismatches in interest rate exposure indicated by the net interest income simulation described above. They are used to modify the Company's exposures to interest rate fluctuations and provide more stable spreads between loan yields and the rate on their funding sources. At December 31, 2013, the Company had $23.8 million in notional amount of outstanding interest rate caps, respectively, to help manage interest rate risk. Derivative financial instruments are also discussed in Item 8, Note 8 - Derivative Financial Instruments.

Impact of Inflation and Changing Prices

The impact of inflation on our operations is increased operating costs. Unlike most industrial companies, virtually all the assets and liabilities of a financial institution are monetary in nature. As a result, interest rates generally have a more significant impact on a financial institution’s performance than the effect of general levels of inflation. Although interest rates do not necessarily move in the same direction or to the same extent as the prices of goods and services, increases in inflation generally have resulted in increased interest rates.

54

Contractual Obligations, Off-Balance Sheet Risk, and Contingent Liabilities

Through the normal course of operations, the Company has entered into certain contractual obligations and other commitments. Such obligations relate to funding of operations through deposits or debt issuances, as well as leases for premises and equipment. As a financial services provider, the Company routinely enters into commitments to extend credit. While contractual obligations represent future cash requirements of the Company, a significant portion of commitments to extend credit may expire without being drawn upon. Such commitments are subject to the same credit policies and approval process accorded to loans made by the Company.

The required contractual obligations and other commitments, excluding any contractual interest(1), at December 31, 2013 were as follows:

(in thousands)	Total	Less Than 1 Year	Over 1 Year Less than 3 Years	Over 3 Years Less than 5 Years	Over 5 Years
Operating leases	18,057	2,570	4,780	3,940	6,767
Certificates of deposit	632,915	375,151	205,434	52,328	2
Subordinated debentures	62,581	—	—	—	62,581
Federal Home Loan Bank advances	50,000	—	—	50,000	—
Notes payable	10,500	1,200	9,300	—	—
Commitments to extend credit	804,420	569,921	141,994	60,349	32,156
Commitments - state tax credits	4,050	225	3,825	—	—
Standby letters of credit	44,376	44,376	—	—	—
Private equity funds (2)	6,069	—	6,069	—	—

(1) In the banking industry, interest-bearing obligations are principally utilized to fund interest-earning assets. As such, interest charges on related contractual obligations were excluded from reported amounts as the potential cash outflows would have corresponding cash inflows from interest-earning assets.

(2) Represents the estimated timing of various capital raises for private equity investments.

As of December 31, 2013, we had liabilities associated with uncertain tax positions of $0.8 million. The table above does not include these liabilities due to the high degree of uncertainty regarding the future cash flows associated with these amounts.

The Company also enters into derivative contracts under which the Company either receives cash from or pays cash to counterparties depending on changes in interest rates. Derivative contracts are carried at fair value on the consolidated balance sheet with the fair value representing the net present value of expected future cash receipts or payments based on market interest rates as of the balance sheet date. The fair value of these contracts changes daily as market interest rates change.

CRITICAL ACCOUNTING POLICIES

The following accounting policies are considered most critical to the understanding of the Company's financial condition and results of operations. These critical accounting policies require management's most difficult, subjective and complex judgments about matters that are inherently uncertain. Because these estimates and judgments are based on current circumstances, they may change over time or prove to be inaccurate based on actual experiences. In the event that different assumptions or conditions were to prevail, and depending upon the severity of such changes, the possibility of a materially different financial condition and/or results of operations could reasonably be expected. The impact and any associated risks related to our critical accounting policies on our business operations are discussed throughout “Management's Discussion and Analysis of Financial Condition and Results of Operations,” where such policies affect

55

our reported and expected financial results. For a detailed discussion on the application of these and other accounting policies, see Item 8, Note 1 - Summary of Significant Accounting Policies.

The Company has prepared all of the consolidated financial information in this report in accordance with U.S. GAAP. The Company makes estimates and assumptions that affect the reported amount of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Such estimates include the valuation of loans, goodwill, intangible assets, and other long-lived assets, along with assumptions used in the calculation of income taxes, among others. These estimates and assumptions are based on management's best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. We adjust such estimates and assumptions when facts and circumstances dictate. Decreased real estate values, volatile credit markets, and persistent high unemployment have combined to increase the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in estimates resulting from continuing changes in the economic environment will be reflected in the financial statement in future periods. There can be no assurances that actual results will not differ from those estimates.

Allowance for Loan Losses

The Company maintains an allowance for loan losses (“the allowance”), which is management's estimate of probable, inherent losses in the outstanding loan portfolio. The allowance is based on management's continuing review and evaluation of the loan portfolio. The review and evaluation combines several factors including: consideration of past loan loss experience; trends in past due and nonperforming loans; changes in lending policies and procedures; existing business and economic conditions; the fair value of underlying collateral; changes in the nature and volume of the Company's loan portfolio; changes in the lending department of the Company; volume and severity of past due loans; the quality of the loan review system; concentrations of credit and other qualitative and other factors which affect probable credit losses. Because current economic conditions can change and are difficult to predict, the anticipated amount of estimated loan losses, and therefore the adequacy of the allowance, could change significantly.

In determining the allowance and the related provision for loan losses for Portfolio Loans, three principal elements are considered:

1) specific allocations based upon probable losses identified during a quarterly review of the loan portfolio,

2) allocations based principally on the Company's risk rating formulas, and

3) a qualitative adjustment based on other economic, environmental and portfolio factors.

The first element reflects management's estimate of probable losses based upon a systematic review of specific loans considered to be impaired. These estimates are based upon discounted cash flows as estimated and used to assign loss or collateral exposure, if they are collateral dependent for collection.

The second element reflects the application of our loan rating system. Loans are rated and assigned a loss allocation factor for each category that is based on a loss migration analysis using the Company's loss experience over the last 3 years. The higher the rating assigned to a loan, the greater the loss allocation percentage that is applied. This element also incorporates an estimate of the loss emergence period. The process is an estimate and is therefore imprecise. As an example, the loss emergence period is the time between when a credit event occurs and the charge-off of a loan. If our estimate of the loss emergence period would have been increased/decreased by one quarter, it would have resulted in a $1.5 million increase and $1.4 million decrease, respectively, in our allowance at December 31, 2013.

The qualitative adjustment is based on management's evaluation of conditions that are not directly reflected in the loss migration analysis and/or specific reserve. The evaluation of the inherent loss with respect to these conditions is subject to a higher degree of uncertainty because they may not be identified with specific problem credits. The conditions evaluated in connection with the qualitative or environmental adjustment include the following:

• changes in lending policies and procedures;

• changes in business and economic conditions;

56

• changes in the nature and volume of our loan portfolio;

• changes in our lending department;

• changes in volume and/or severity of past due loans;

• changes in the quality of our loan review system;

• changes in the value of underlying collateral related to loans;

• existence and effect of concentrations of credit within our loan portfolio; and

• other external factors such as asset quality trends (including trends in nonperforming loans expected to result from existing conditions), related allowance metrics of our peers

Executive management reviews these conditions quarterly by portfolio segment based on discussion with our lending staff. Management then assigns a specified number of basis points of allowance to each factor above by portfolio segment. To the extent that any of these conditions is evidenced by a specifically identifiable problem credit or portfolio segment as of the evaluation date, management's estimate of the effect of such conditions may be reflected as a specific allowance, applicable to such credit or portfolio segment.

The allocation of the allowance for loan losses by loan category is a result of the analysis above. The allocation methodology applied by the Company focuses on changes in the size and character of the loan portfolio, changes in levels of impaired and other nonperforming loans, the risk inherent in specific loans, concentrations of loans to specific borrowers or industries, existing economic conditions, and historical losses on each portfolio category.

Management believes that the allowance for loan losses is adequate at December 31, 2013.

Loans Acquired Through Transfer

Loans acquired through the completion of a transfer, including loans acquired in a business combination that have evidence of deterioration of credit quality since origination and for which it is probable, at acquisition, that the Company will be unable to collect all contractually required payments receivable. Acquired loans are initially recorded at fair value (as determined by the present value of expected future cash flows) with no valuation allowance. The difference between the undiscounted cash flows expected at acquisition and the investment in the loans, or the “accretable yield,” is recognized as interest income on a level-yield method over the life of the loans. Contractually required payments for interest and principal that exceed the undiscounted cash flows expected at acquisition, or the “nonaccretable difference,” are not recognized as a yield adjustment or as a loss accrual or a valuation allowance. The Company aggregates individual loans with common risk characteristics into pools of loans. Increases in expected cash flows subsequent to the initial investment are recognized prospectively through adjustment of the yield on the loans over their remaining lives. Decreases in expected cash flows due to an inability to collect contractual cash flows are recognized as impairment through the provision for loan losses account. Any allowance for loan loss on these pools reflect only losses incurred after the acquisition. Any disposals of loans, including sales of loans, payments in full or foreclosures result in the removal of the loan from the loan pool at the carrying amount with differences in actual results reflected in interest income.

Acquired impaired loans are generally considered accruing and performing as the loans accrete income over the estimated life of the loan, in circumstances where cash flows are reasonably estimable by management. Accordingly, acquired impaired loans that could be contractually past due could be considered to be accruing and performing. If the timing and amount of future cash flows is not reasonably estimable, the loans may be classified as nonaccrual loans and the purchase price discount on those loans is not recorded as interest income until the timing and amount of future cash flows can be reasonably estimable.

Allowance for Loan Losses on Purchase Credit Impaired Acquired Loans

The Company updates its cash flow projections for purchase credit-impaired loans, including loans acquired from the FDIC, on a quarterly basis. Assumptions utilized in this process include projections related to probability of default, loss severity, prepayment, extensions and recovery lag. Projections related to probability of default and prepayment are calculated utilizing a loan migration analysis. The loan migration analysis is a matrix that specifies the probability

57

of a loan pool transitioning into a particular delinquency or liquidation state given its current performance at the measurement date. Loss severity factors are based upon industry data and historical experience.

Any decreases in expected cash flows after the acquisition date and subsequent measurement periods are recognized by recording an impairment in allowance for loan losses through a provision for loan losses. For loans covered by FDIC loss share, the FDIC loss share receivable is increased to reflect future cash to be received from the FDIC. The amount of the increase is recorded in noninterest income and is determined based on the specific loss share agreement, but is generally 80% of the losses. See Loans Acquired Through Transfer above for further discussion. Any increase in expected future cash flows due to a decrease in expected credit losses will reverse previously recorded impairment, if any, and add to the accretable yield on the loan pool, prospectively. In addition the accretion of the FDIC loss share receivable will decrease prospectively over the remaining life. Increases and decreases to the FDIC loss share receivable are recorded as adjustments to noninterest income.

Goodwill and Other Intangible Assets

Our goodwill impairment test is completed in the fourth quarter each year or whenever events or changes in circumstances indicate that the Company may not be able to recover the goodwill, or intangible assets, respective carrying amount. In 2013, we performed a qualitative ("Step 0") assessment to determine if our goodwill was impaired. The qualitative assessment involved the examination of changes that have occurred since our last quantitative ("Step 1") goodwill impairment test took place including macroeconomic conditions, industry and market conditions, overall financial performance, changes in management and other key personnel, changes in our reporting units, and changes in the share price of the Company's common stock. Based on the Step 0 assessment, Management believes it is probable that its goodwill is not impaired.

Goodwill is evaluated for impairment at the reporting unit level. Reporting units are defined as the same level as, or one level below, an operating segment. An operating segment is a component of a business for which separate financial information is available that management regularly evaluates in deciding how to allocate resources and assess performance. The Company's reporting units are Banking and Wealth Management operations of Enterprise Bank & Trust. At December 31, 2013 and 2012, the Banking and Wealth Management reporting units had $30.3 million and zero goodwill, respectively.

Businesses must identify potential impairments by performing the qualitative assessment noted above or when a formal test is required comparing the fair value of a reporting unit to its carrying amount, including goodwill. Goodwill impairment does not occur as long as it is probable an impairment has not occurred under the Step 0 assessment or the fair value of the unit is greater than its carrying value under the Step 1 assessment. The second step ("Step 2") of the impairment test is only required if the carrying value of the reporting unit is greater than its fair value as determined in Step 1. Step 2 of the test compares the implied fair market value of goodwill to its carrying amount. If the carrying amount of goodwill exceeds its implied fair market value, an impairment loss is recognized. That loss is equal to the carrying amount of goodwill that is in excess of its implied fair market value.

Intangible assets other than goodwill, such as core deposit intangibles, that are determined to have finite lives are amortized over their estimated remaining useful lives. These assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset.

The 2013 annual impairment evaluation of goodwill and intangible balances did not identify any impairment.

58

Deferred Tax Assets and Liabilities

The Company accounts for income taxes under the asset/liability method. Deferred tax assets and liabilities are recognized for future tax effects of temporary differences, net operating loss carry forwards and tax credits. Deferred tax assets are reduced if necessary, by a deferred tax asset valuation allowance. A valuation allowance is established when in the judgment of management, it is more likely than not that such deferred tax assets will not become realizable. In this case, we would adjust the recorded value of our deferred tax assets, which would result in a direct charge to income tax expense in the period that the determination is made. Likewise, we would reverse the valuation allowance when realization of the deferred tax asset is expected. At December 31, 2013, the Company did not have any valuation allowances for federal or state income taxes.

Effects of New Accounting Pronouncements

See Item 8, Note 24 - New Authoritative Accounting Guidance for information on recent accounting pronouncements and their impact, if any, on our consolidated financial statements.

Use of Non-GAAP Financial Measures:

The Company's accounting and reporting policies conform to generally accepted accounting principles ("GAAP") in the U.S. and the prevailing practices in the banking industry. However, the Company provides other financial measures, such as Core net interest margin, tangible common equity ratio and Tier 1 common equity ratio, in this filing that are considered “non-GAAP financial measures.” Generally, a non-GAAP financial measure is a measure of a company's financial performance, financial position or cash flows that exclude (or include) amounts that are included in (or excluded from) the most directly comparable measure calculated and presented in accordance with U.S. GAAP.

The Company believes that Core net interest margin is an important measure of our financial performance, even though it is a non-GAAP financial measure, because it provides supplemental information by which to evaluate the impact of excess Covered loan accretion on the Company's net interest margin and the Company's operating performance on an ongoing basis, excluding such impact. The table below reconciles Core net interest margin to the most comparable number under U.S. GAAP.

The Company believes these non-GAAP financial measures and ratios, when taken together with the corresponding

U.S. GAAP measures and ratios, provide meaningful supplemental information regarding the Company's performance and capital strength. The Company's management uses, and believes that investors benefit from referring to, these non-GAAP measures and ratios in assessing the Company's financial and operating results and related trends and when planning and forecasting future periods. However, these non-GAAP measures and ratios should be considered in addition to, and not as a substitute for or preferable to, ratios prepared in accordance with U.S. GAAP. The Company has provided a reconciliation of, where applicable, the most comparable GAAP financial measures and ratios to the non-GAAP financial measures and ratios, or a reconciliation of the non-GAAP calculation of the financial measure.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

Enterprise Financial Services Corp

St. Louis, Missouri

We have audited the accompanying consolidated balance sheets of Enterprise Financial Services Corp and subsidiaries (the "Company") as of December 31, 2013 and 2012, and the related consolidated statements of operations, comprehensive income, shareholders' equity, and cash flows for each of the three years in the period ended December 31, 2013. These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall consolidated financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Enterprise Financial Services Corp and subsidiaries as of December 31, 2013 and 2012, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2013, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company's internal control over financial reporting as of December 31, 2013, based on the criteria established in Internal Control - Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 17, 2014 expressed an unqualified opinion on the Company's internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

Enterprise Financial Services Corp

St. Louis, Missouri

We have audited the internal control over financial reporting of Enterprise Financial Services Corp and subsidiaries (the "Company") as of December 31, 2013, based on criteria established in Internal Control - Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Assessment on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of consolidated financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the consolidated financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2013, based on the criteria established in Internal Control - Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements as of and for the year ended December 31, 2013 of the Company and our report dated March 17, 2014 expressed an unqualified opinion on those consolidated financial statements.

ENTERPRISE FINANCIAL SERVICES CORP AND SUBSIDIARIES

Notes to Consolidated Financial Statements

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The significant accounting policies used by the Company in the preparation of the consolidated financial statements are summarized below:

Business and Consolidation

Enterprise Financial Services Corp and subsidiaries (the “Company” or “Enterprise”) is a financial holding company that provides a full range of banking and wealth management services to individuals and corporate customers located in the St. Louis, Kansas City and Phoenix metropolitan markets through its banking subsidiary, Enterprise Bank & Trust (the “Bank”). The consolidated financial statements include the accounts of the Company, and its subsidiaries, all of which are wholly owned. All intercompany accounts and transactions have been eliminated.

The Company is subject to competition from other financial and nonfinancial institutions providing financial services in the markets served by the Company's subsidiary. Additionally, the Company and its banking subsidiary are subject to the regulations of certain federal and state agencies and undergo periodic examinations by those regulatory agencies.

Adoption of New Accounting Guidance

The Company has adopted the accounting guidance within ASU 2014-1 "Investments-Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects." As required by the ASU, the Company revised its prior period financial statements to move the losses associated with its investments from Other noninterest expense to income tax expense. The impact of the revision to adopt the ASU was a decrease in Other Non-interest Expense and a similar increase in Income Tax Expense of $0.9 million for the years ended December 31, 2013, 2012 and 2011, respectively.

Use of Estimates

The consolidated financial statements of the Company have been prepared in conformity in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”.) In preparing the consolidated financial statements, management is required to make estimates and assumptions, which significantly affect the reported amounts in the consolidated financial statements. Such estimates include the valuation of loans, goodwill, intangible assets, indemnification assets, and other long-lived assets, along with assumptions used in the calculation of income taxes, among others. These estimates and assumptions are based on management's best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. Management adjusts such estimates and assumptions when facts and circumstances dictate. Decreased real estate values, volatile credit markets, and persistent high unemployment have combined to increase the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.

Cash Flow Information

For purposes of reporting cash flows, the Company considers cash and due from banks, interest-bearing deposits and federal funds sold that mature within 90 days to be cash and cash equivalents. At December 31, 2013 and 2012, approximately $16.8 million and $16.5 million, respectively, of cash and due from banks represented required reserves on deposits maintained by the Company in accordance with Federal Reserve Bank requirements.

Investments

The Company has classified all investments in debt securities as available for sale.

70

Securities classified as available for sale are carried at fair value. Unrealized holding gains and losses for available for sale securities are excluded from earnings and reported as a net amount in a separate component of shareholders' equity until realized. All previous fair value adjustments included in the separate component of shareholders' equity are reversed upon sale.

Declines in the fair value of securities below their cost that are deemed to be other-than-temporary are reflected in operations as realized losses. In estimating other-than-temporary impairment losses, management systematically evaluates investment securities for other-than-temporary declines in fair value on a quarterly basis.  This analysis requires management to consider various factors, which include (1) the present value of the cash flows expected to be collected compared to the amortized cost of the security, (2) duration and magnitude of the decline in value, (3) the financial condition of the issuer or issuers, (4) structure of the security, and (5) the intent to sell the security or whether it's more likely than not that the Company would be required to sell the security before its anticipated recovery in market value.

Premiums and discounts are amortized or accreted over the expected lives of the respective securities as an adjustment to yield using the interest method. Dividend and interest income is recognized when earned. Realized gains and losses are included in earnings and are derived using the specific identification method for determining the cost of securities sold.

Loans Held for Sale

The Company provides long-term financing of one-to-four-family residential real estate by originating fixed and variable rate loans. Long-term fixed and variable rate loans are sold into the secondary market with limited recourse. Upon receipt of an application for a real estate loan, the Company determines whether the loan will be sold into the secondary market or retained in the Company's loan portfolio. The interest rates on the loans sold are locked with the buyer and the Company bears no interest rate risk related to these loans. Mortgage loans held for sale are carried at the lower of cost or fair value, which is determined on a specific identification method. The Company does not retain servicing on any loans sold, nor did the Company have any capitalized mortgage servicing rights at December 31, 2013 or 2012. Gains on the sale of loans held for sale are reported net of direct origination fees and costs in the Company's consolidated statements of operations.

Portfolio Loans

Loans are reported at the principal balance outstanding net of unearned fees and costs. Loan origination fees and direct origination costs are deferred and recognized over the lives of the related loans as a yield adjustment using the interest method.

Interest income on loans is accrued to income based on the principal amount outstanding. The recognition of interest income is discontinued when a loan becomes 90 days past due or a significant deterioration in the borrower's credit has occurred which, in management's judgment, negatively impacts the collectability of the loan. Unpaid interest on such loans is reversed at the time the loan becomes uncollectable and subsequent interest payments received are applied to principal if any doubt exists as to the collectability of such principal; otherwise, such receipts are recorded as interest income. Loans that have not been restructured are returned to accrual status when management believes full collectability of principal and interest is expected. Non-accrual loans that have been restructured will remain in a non-accrual status until the borrower has made six consecutive contractual payments.

Loans Acquired Through Transfer

Loans acquired through the completion of a transfer, including loans acquired in a business combination that have evidence of deterioration of credit quality since origination and for which it is probable, at acquisition, that the Company will be unable to collect all contractually required payments receivable, are initially recorded at fair value (as determined by the present value of expected future cash flows) with no valuation allowance. The difference between the undiscounted cash flows expected at acquisition and the investment in the loans, or the “accretable yield,” is recognized as interest income on a level-yield method over the life of the loans. Contractually required payments for interest and principal that exceed the undiscounted cash flows expected at acquisition, or the “nonaccretable difference,” are not recognized as a yield adjustment or as a loss accrual or a valuation allowance. The Company aggregates individual loans with common risk characteristics into pools of loans. Increases in expected cash flows subsequent to the initial

71

investment are recognized prospectively through adjustment of the yield on the loans over their remaining lives. Decreases in expected cash flows due to an inability to collect contractual cash flows are recognized as impairment through the provision for loan losses account. Any allowance for loan loss on these pools reflect only losses incurred after the acquisition (meaning the present value of all cash flows expected at acquisition that ultimately are not to be received). Any disposals of loans, including sales of loans, payments in full or foreclosures result in the removal of the loan from the loan pool at the carrying amount with differences in actual results reflected in interest income.

Impaired Loans

Loans are considered “impaired” when it becomes probable that the Company will be unable to collect all amounts due according to the loan's contractual terms. Non-accrual loans, loans past due greater than 90 days and still accruing, unless adequately secured and in the process of collection, and restructured loans qualify as “impaired loans.” Restructured loans involve the granting of a concession to a borrower experiencing financial difficulty involving the modification of terms of the loan, such as changes in payment schedule or interest rate.

When measuring impairment, the expected future cash flows of an impaired loan are discounted at the loan's effective interest rate at origination. Alternatively, impairment can be measured by reference to an observable market price, if one exists, or the fair value of the collateral for a collateral-dependent loan. Interest income on impaired loans is not accrued but is recorded when cash is received and only if principal is considered to be fully collectable. Loans and leases, which are deemed uncollectable, are charged off to the allowance for loan losses, while recoveries of amounts previously charged off are credited to the allowance for loan losses.

Impaired loans exclude credit-impaired loans that were acquired in the FDIC-assisted transactions. These purchased credit-impaired loans are accounted for on a pool basis and are generally considered accruing and performing loans as the loans accrete interest income over the estimated life of the loan when cash flows are reasonably estimable. Accordingly, acquired credit impaired loans that are contractually past due may still be considered to be accruing and performing loans. If the timing and amount of future cash flows is not reasonably estimable, the loans may be classified as nonaccrual loans and the purchase price discount on those loans is not recorded as interest income until the timing and amount of future cash flows can be reasonably estimated. See Note 2 - Acquisitions and Divestitures and Note 7 - Purchase Credit Impaired ("PCI") Loans for more information on these loans.

Loan Charge-Offs

Loans are charged-off when the primary and secondary sources of repayment (cash flow, collateral, guarantors, etc) are less than their carrying value.

Allowance For Loan Losses

The allowance for loan losses is increased by provision charged to expense and is available to absorb charge-offs, net of recoveries. Management utilizes a systematic, documented approach in determining the appropriate level of the allowance for loan losses. The level of the allowance reflects management's continuing evaluation of industry concentrations; specific credit risks; loan loss experience; current loan portfolio quality; present economic, political and regulatory conditions; and probable losses inherent in the current loan portfolio. The determination of the appropriate level of the allowance for loan losses inherently involves a degree of subjectivity and requires that the Company make significant estimates of current credit risks and future trends, all of which may undergo material changes. Changes in economic conditions affecting borrowers, new information regarding existing loans, identification of additional problem loans and other factors, both within and outside of our control, may require an increase in the allowance for loan losses.

Management believes the allowance for loan losses is adequate to absorb inherent losses in the loan portfolio. While management uses available information to recognize losses on loans, future additions to the allowance may be necessary based on changes in economic conditions and other factors. In addition, various regulatory agencies, as an integral part of the examination process, periodically review the Bank's loan portfolio. Such agencies may require additions to the allowance for loan losses based on their judgments and interpretations of information available to them at the time of their examinations.

72

Allowance for Loan Losses on Purchase Credit Impaired Loans

The Company updates its cash flow projections for purchase credit impaired loans, including loans acquired with FDIC loss share coverage, on a quarterly basis. Assumptions utilized in this process include projections related to probability of default, loss severity, prepayment, extensions and recovery lag. Projections related to probability of default and prepayment are calculated utilizing a loan migration analysis. The loan migration analysis is a matrix of probability that specifies the probability of a loan pool transitioning into a particular delinquency or liquidation state given its current state at the re-measurement date. Loss severity factors are based upon industry data.

Any decreases in expected cash flows after the acquisition date and subsequent measurement periods are recognized by recording an impairment in the provision for loan losses. As a result of impairment, the FDIC loss share receivable is increased to reflect future cash to be received from the FDIC. The amount of the increase is recorded in noninterest income and is determined based on the specific loss share agreement, but is generally 80% of the losses. See Loans Acquired Through Transfer above for further discussion. Any increase in expected future cash flows due to a decrease in expected credit losses will reverse previously recorded impairment, if any, and add to the accretable yield on the loan pool, prospectively. In addition the accretion of the FDIC loss share receivable will decrease prospectively over the remaining life. Increases and decreases to the FDIC loss share receivable are recorded as adjustments to noninterest income.

Other Real Estate

Other real estate represents property acquired through foreclosure or deeded to the Company in lieu of foreclosure on loans on which the borrowers have defaulted on the payment of principal or interest. Other real estate is recorded on an individual asset basis at the lower of cost or fair value less estimated costs to sell. The fair value of other real estate is based upon estimates of future cash flows, market value of similar assets, if available, or independent appraisals. These estimates involve significant uncertainties and judgments. As a result, fair value estimates may not be realizable in a current sale or settlement of the other real estate. Subsequent reductions in fair value are expensed within noninterest expense.

Gains and losses resulting from the sale of other real estate are credited or charged to current period earnings. Costs of maintaining and operating other real estate are expensed as incurred, and expenditures to complete or improve other real estate properties are capitalized if the expenditures are expected to be recovered upon ultimate sale of the property.

FDIC Loss Share Receivable and Clawback Liability

As part of the FDIC- assisted transactions, the Bank entered into loss sharing agreements with the FDIC. The FDIC will reimburse the Bank for a percentage of realized losses on loans and foreclosed real estate covered under the agreement (“Covered Assets”). In addition, the Bank will be reimbursed for certain expenses related to the Covered Assets. At the acquisition date, the fair value of the amount due from the FDIC (“FDIC Loss Share Receivable") was estimated based on expected losses and cash flows on the Covered Assets. The FDIC Loss Share Receivable is measured separately from the related Covered Assets and recorded separately on the balance sheet because it is not contractually embedded in the Covered Assets and is not transferable.  Although these assets are contractual receivables from the FDIC, there are no contractual interest rates. See Note 2 - Acquisitions and Divestitures, for further information regarding these transactions.

Subsequent to initial recognition, the FDIC Loss Share Receivable is reviewed quarterly and adjusted for any changes in expected cash flows. These adjustments are measured on the same basis as the related Covered Assets. Any decrease in expected cash flows due to an increase in expected credit losses will increase the FDIC Loss Share Receivable which will partially offset the impairment recorded on the PCI loans. Any increase in expected future cash flows due to a decrease in expected credit losses will decrease the accretion of the FDIC Loss Share Receivable prospectively over its remaining life. Increases and decreases to the FDIC Loss Share Receivable are recorded as adjustments to noninterest income.

As stipulated in some of its agreements with the FDIC, the Company may be required to reimburse the FDIC if certain levels of cash flows are met over the duration of a loss share agreement. This reimbursement, or clawback liability, is measured quarterly over the duration of the agreement.

73

Fixed Assets

Buildings, leasehold improvements,furniture, fixtures, equipment, and capitalized software are stated at cost less accumulated depreciation. All categories are computed using the straight-line method over their respective estimated useful lives. Furniture, fixtures and equipment is depreciated over three to ten years, buildings and leasehold improvements over ten to forty years, and capitalized software over three years based upon estimated lives or lease obligation periods.

State Tax Credits Held for Sale

The Company has purchased the rights to receive 10-year streams of state tax credits at agreed upon discount rates and sells such tax credits to wealth management customers and others. All state tax credits purchased prior to 2009 are accounted for at fair value. All state tax credits purchased since 2009 are accounted for at cost. The Company elected not to account for the state tax credits purchased since 2009 at fair value in order to limit the volatility of the fair value changes in the Company's consolidated statements of operations.

Cash Surrender Value of Life Insurance

The Company has purchased bank-owned life insurance policies on certain bank officers.  Bank-owned life insurance is recorded at its cash surrender value.  Changes in the cash surrender values are included in noninterest income.

Federal Home Loan Bank Stock

The Bank, as a member of the Federal Home Loan Bank of Des Moines (“FHLB”), is required to maintain an investment in the capital stock of the FHLB. The stock is redeemable at par by the FHLB, and is therefore, carried at cost and periodically evaluated for impairment.  The Company records FHLB dividends in interest income on the ex-dividend date.

Goodwill and Other Intangible Assets

The Company tests goodwill for impairment on an annual basis and whenever events or changes in circumstances indicate that the Company may not be able to recover the respective asset's carrying amount. The Company's annual test for impairment was performed in the fourth quarter of 2013. Such tests involve the use of estimates and assumptions. Core deposit intangibles are amortized using an accelerated method over an estimated useful life of approximately 10 years.

The Company identifies potential goodwill impairments by first performing a qualitative assessment and then by comparing the fair value of a reporting unit to its carrying amount, including goodwill. Goodwill impairment is not indicated as long as it is more likely than not that impairment has not occurred based on the qualitative assessment or based on the quantitative assessment the fair value of the reporting unit is greater than its carrying value. The second step of the impairment test is only required if a goodwill impairment is identified in step one. The second step of the test compares the implied fair value of goodwill to its carrying amount. If the carrying amount of goodwill exceeds its implied fair value, an impairment loss is recognized. That loss is equal to the carrying amount of goodwill that is in excess of its implied fair market value.

Impairment of Long-Lived Assets

Long-lived assets, such as fixed assets and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are separately presented in the balance sheet and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposal group classified as held for sale are presented separately in the appropriate asset and liability sections of the balance sheet.

74

Derivative Financial Instruments and Hedging Activities

The Company uses derivative financial instruments to assist in the management of interest rate sensitivity and to modify the repricing, maturity and option characteristics of certain assets and liabilities. In addition, the Company also offers an interest rate hedge program that includes interest rate swaps to assist its customers in managing their interest rate risk profile. In order to eliminate the interest rate risk associated with offering these products, the Company enters into derivative contracts with third parties to offset the customer contracts. 

Derivative instruments are required to be measured at fair value and recognized as either assets or liabilities in the consolidated financial statements. Fair value represents the payment the Company would receive or pay if the item were sold or bought in a current transaction. The accounting for changes in fair value (gains or losses) of a hedged item is dependent on whether the related derivative is designated and qualifies for “hedge accounting.” The Company assigns derivatives to one of these categories at the purchase date: cash flow hedge, fair value hedge, or non-designated derivatives. An assessment of the expected and ongoing hedge effectiveness of any derivative designated a fair value hedge or cash flow hedge is performed as required by the accounting standards. Derivatives are included in other assets and other liabilities in the consolidated balance sheets. Generally, the only derivative instruments used by the Company have been interest rate swaps and interest rate caps.

The following is a summary of the Company's accounting policies for derivative instruments and hedging activities.

• Cash Flow Hedges - Derivatives designated as cash flow hedges are recorded at fair value. The effective portion of the change in fair value is recorded (net of taxes) as a component of other comprehensive income (“OCI”) in shareholders' equity. Amounts recorded in OCI are subsequently reclassified into interest income or expense (depending on whether the hedged item is an asset or liability) when the underlying transaction affects earnings. The ineffective portion of the change in fair value is recorded in noninterest income. Upon dedesignation of a derivative financial instrument from a cash flow hedge relationship, any remaining amounts in OCI are recorded in noninterest income over the expected remaining life of the underlying forecasted hedge transaction. The net interest differential between the hedged item and the hedging derivative financial instrument are recorded as an adjustment to interest income or interest expense of the related asset or liability.

• Fair Value Hedges - For derivatives designated as fair value hedges, the change in fair value of the derivative instrument and related hedged item are recorded in the related interest income or expense, as applicable, except for the ineffective portion, which is recorded in noninterest income in the consolidated statements of income. The swap agreement is accounted for on an accrual basis with the net interest differential being recognized as an adjustment to interest income or interest expense of the related asset or liability.

• Non-Designated Derivatives - Certain derivative financial instruments are not designated as cash flow or as fair value hedges for accounting purposes. These non-designated derivatives are intended to provide interest rate protection on net interest income or noninterest income but do not meet hedge accounting treatment. Customer accommodation interest rate swap contracts are not designated as hedging instruments. Changes in the fair value of these instruments are recorded in interest income or noninterest income in the consolidated statements of income depending on the underlying hedged item.

75

Income Taxes

The Company and its subsidiaries file a consolidated federal income tax return. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. We evaluated the need for deferred tax asset valuation allowances based on a more-likely-than-not standard. The ability to realize deferred tax assets depends on the ability to generate sufficient positive taxable income within the carryback or carryforward periods provided for in the laws for each applicable taxing jurisdiction. We consider the following possible sources of taxable income: future reversal patterns of existing taxable temporary differences, future taxable income exclusive of reversing temporary differences, taxable income in prior carryback years and the availability of qualified tax planning strategies. The assessment regarding whether a valuation allowance is required or should be adjusted depends on all available positive and negative factors including, but not limited to, nature, frequency, and severity of recent losses, duration of available carryforward periods, historical experience with tax attributes expiring unused and near and medium term financial outlook. Because of the complexity of tax laws and regulations, interpretation can be difficult and subject to legal judgment given specific facts and circumstances. It is possible that others, given the same information, may at any point in time reach different reasonable conclusions regarding the estimated amounts of accrued taxes.

Stock-Based Compensation

Stock-based compensation is recognized as an expense in the consolidated financial statements and measured at the grant date fair value for all equity classified awards and recognized over the required service period.

Acquisitions and Divestitures

The Company accounts for business combinations using the acquisition method of accounting. Accordingly, the assets and liabilities of the acquired entities have been recorded at their estimated fair values at the date of acquisition. Goodwill represents the excess of the purchase price over the fair value of net assets, including the amount assigned to identifiable intangible assets.

The purchase price allocation process requires an estimation of the fair values of the assets acquired and the liabilities assumed. When a business combination agreement provides for an adjustment to the cost of the combination contingent on future events, the Company includes an estimate of the acquisition-date fair value as part of the cost of the combination. The results of operations of the acquired business are included in the Company's consolidated financial statements from the respective date of acquisition. As a general rule, goodwill established in connection with a stock purchase is non-deductible for tax purposes.

For divestitures, the Company measures an asset (disposal group) classified as held for sale at the lower of its carrying value at the date the asset is initially classified as held for sale or its fair value less costs to sell. The Company reports the results of operations of a component that either has been disposed of or held for sale as discontinued operations if:

• The operations and cash flows of the disposal group will be eliminated from the ongoing operations as a result of the disposal transaction, and

• The Company will not have any significant continuing involvement in the operations of the entity after the disposal transaction.

Any incremental direct costs incurred to transact the sale are allocated against the gain or loss on the sale. These costs would include items like legal fees, title transfer fees, broker fees, etc. Any goodwill and intangible assets associated with the portion of the reporting unit to be disposed of is included in the carrying amount of the business in determining the gain or loss on the sale.

Basic and Diluted Earnings Per Common Share

Basic earnings per common share data is calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Common shares outstanding include common stock and restricted stock awards where recipients have satisfied the vesting terms. Diluted earnings per

76

common share gives effect to all dilutive potential common shares outstanding during the period using the treasury stock method and the if-converted method for convertible securities related to the issuance of trust preferred securities.

Consolidated Statement of Comprehensive Income

The Consolidated Statement of Comprehensive Income includes the amount and the related tax impact that have been reclassified from accumulated other comprehensive income to net income. The classification adjustment for unrealized loss/gain on sale of securities included in net income has been recorded through the gain on sale of investment securities line item, within noninterest income, in the Company's Consolidated Statements of Operations.

NOTE 2 - ACQUISITIONS & DIVESTITURES

FDIC-Assisted Transactions

The PCI loans acquired were recorded at estimated fair value. As such, there was no allowance for credit losses established related to the acquired loans at the various acquisition dates and no carryover of the related allowance from the failed banks. The loans are accounted for in accordance with guidance for certain loans acquired in a transfer, when the loans have evidence of credit deterioration and it is probable at the date of acquisition that the acquirer will not collect all contractually required principal and interest payments. The difference between contractually required payments and the cash flows expected to be collected at acquisition is referred to as the non-accretable difference. Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent increases in cash flows result in a reversal of the provision for loan losses to the extent of prior charges and an adjustment in accretable yield, which will have a positive impact on interest income, prospectively.

In connection with each acquisition, the Bank also entered into a shared-loss agreement whereby the FDIC will reimburse the Bank for a percentage of all losses incurred on certain loans and other real estate covered under the agreement. The shared-loss agreements are subject to the servicing procedures as specified in the agreement with the FDIC. The shared-loss agreements applicable to single-family residential mortgage loans have terms of ten (10) years, while the shared-loss agreements applicable to all other Covered Assets have terms of five (5) years, while requiring the Bank to reimburse the FDIC for any recoveries of such shared losses for a period of eight (8) years.

The reimbursable losses from the FDIC were recorded at fair value as of the date of acquisition based on the present value of expected cash flows from the reimbursement of credit losses on the Covered Assets. These reimbursable losses, which are recorded as FDIC loss share receivable on the Consolidated Balance Sheets, are measured separately from the Covered Assets as the shared-loss agreement with the FDIC is not contractually embedded in or transferable with the Covered Assets. Reimbursements received from the FDIC for actual incurred losses will reduce the FDIC loss share receivable. Subsequent measurements of the remaining loss reimbursements under the shared-loss agreement are determined on the same basis as the Covered Assets. In certain circumstances, reductions to the expected losses on the Covered Assets will result in the amortization of the FDIC loss share receivable. Any amortization of the FDIC loss share receivable shall be limited to the lesser of the contractual terms of the shared-loss agreement and the remaining life of the Covered Assets. Additional expected losses, to the extent such expected losses result in a provision for loan losses, will increase the FDIC loss share receivable.

The Company has omitted certain pro forma financial information surrounding its FDIC-Assisted Transactions as allowed under Staff Accounting Bulletin 1K - Financial Statements of Acquired Troubled Financial Institutions as this information is not reasonably available.

Acquisition of The First National Bank of Olathe

On August 12, 2011, the Bank entered into a purchase and assumption agreement with the FDIC and acquired certain assets and assumed certain liabilities of FNBO, headquartered in Olathe, Kansas, a national bank chartered by the Office of the Comptroller of the Currency.

The Company provided the FDIC with a Value Appreciation Instrument (“VAI”) whereby 1.0 million units were awarded to the FDIC at an exercise price of $13.59 per unit. The units were exercisable any time from August 19,

77

2011 until August 10, 2012. The units were exercised on October 31, 2011 at a settlement price of $15.8393. A cash payment of approximately $2.2 million was made to the FDIC on November 1, 2011.

In connection with the acquisition, the Bank entered into shared-loss agreements with the FDIC that covered approximately $388.2 million of Covered Assets. Pursuant to the terms of the shared-loss agreements, the FDIC will reimburse the Bank for 80% of losses up to $112.6 million, 0% of losses between $112.6 million and $148.9 million and 80% of losses in excess of $148.9 million with respect to Covered Assets. The Bank will reimburse the FDIC for 80% of recoveries with respect to losses for which the FDIC has reimbursed the Bank under the shared-loss agreements.

Acquisition of Legacy Bank

On January 7, 2011, the Bank entered into a purchase and assumption agreement with the FDIC and acquired certain assets and assumed certain liabilities of Legacy, a full service community bank that was headquartered in Scottsdale, Arizona. As part of the acquisition, the Bank also acquired approximately $55.6 million of discretionary and $13.6 million of non-discretionary trust assets. Pursuant to the terms of the of the shared-loss agreement the FDIC will reimburse the Bank for 80% for all losses incurred on Covered Assets.

The Company provided the FDIC with a VAI whereby 372,500 units were awarded to the FDIC at an exercise price of $10.63 per unit. The units were exercisable at any time from January 14, 2011 until January 6, 2012. The FDIC exercised the units on January 20, 2011 at a settlement price of $11.8444. A cash payment of $452,364 was made to the FDIC on January 21, 2011.

Other Acquisitions and Divestitures

Acquisition of Creve Coeur, Missouri branch

On October 21, 2011, the Bank purchased certain assets and assumed certain deposit liabilities from BankLiberty of Liberty, Missouri. The Bank assumed $43.0 million in deposits associated with the BankLiberty branch located at 11401 Olive Boulevard, in the St. Louis suburb of Creve Coeur, Missouri. The deposits consisted of $2.6 million in demand deposits, $21.9 million in money market and other interest bearing deposits, and $18.5 million in certificates of deposit. The Bank also paid a deposit premium of $323,000 on these deposits and purchased $150,000 of personal property in the branch. The Bank executed a sublease on approximately 6,556 square feet at the above address. Enterprise currently operates the location as a full-service branch of the Bank.

Branch Sale

On December 6, 2013 the Company finalized an agreement to sell two of its Kansas City branches to another financial institution. The agreement calls for the sale of substantially all of the deposits at these branches, as well as specified loans and other assets. The Company recorded a pre-tax gain of $1.0 million upon completion of the transaction primarily attributed to a premium on the deposits that were sold.

The following table summarizes the primary balance sheet amounts relative to the branches to be sold:

(in thousands)
Assets
Cash and cash equivalents	$	434
Loans	7,574
Other assets	1,040
Liabilities
Deposits	$	78,431

78

In addition to the branch sale discussed above, the Company closed 2 branches in the Kansas City region. In conjunction with the closure, the Company recorded a liability and corresponding expense of $0.5 million for the difference between the net present value of future lease payments and its estimated sublease income at one of the closed branches. The expense is recorded within other noninterest expense for the year ended December 31, 2013.

NOTE 4 - PREFERRED STOCK AND COMMON STOCK WARRANTS

On December 19, 2008, the Company entered into an agreement with the United States Department of the Treasury (“U.S. Treasury”) under the Capital Purchase Program, pursuant to which the Company sold (i) 35,000 shares of Fixed Rate Cumulative Perpetual Preferred Stock, Series A (“Senior Preferred Stock”) and (ii) a warrant to purchase 324,074 shares of EFSC common stock (“common stock warrants”), par value $0.01 per share, for an aggregate investment by the U.S. Treasury of $35.0 million. On November 7, 2012, the Company repurchased all of the Senior Preferred Stock from the U.S. Treasury for an aggregate purchase price of $35.4 million, which included $399,000 for accrued and unpaid dividends. On January 9, 2013, the Company repurchased the warrants issued to the U.S. Treasury as part of the Capital Purchase Program for approximately $1.0 million. After completing the warrant repurchase the Company ended its participation in the U.S. Treasury Capital Purchase Program.

At December 31, 2013, and December 31, 2012, there were no holdings of securities of any one issuer in an amount greater than 10% of shareholders’ equity, other than the U.S. Government agencies and sponsored enterprises. The agency mortgage-backed securities are all issued by U.S. Government-sponsored enterprises. Available for sale securities having a fair value of $270.1 million and $359.3 million at December 31, 2013, and December 31, 2012, respectively, were pledged as collateral to secure deposits of public institutions and for other purposes as required by law or contract provisions.

The amortized cost and estimated fair value of debt securities classified as available for sale at December 31, 2013, by contractual maturity, are shown below. Expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. The weighted average life of the mortgage-backed securities is approximately 5 years.

The unrealized losses at both December 31, 2013, and December 31, 2012, were primarily attributable to changes in market interest rates since the securities were purchased. Management systematically evaluates investment securities for other-than-temporary declines in fair value on a quarterly basis. This analysis requires management to consider various factors, which include among other considerations (1) the present value of the cash flows expected to be collected compared to the amortized cost of the security, (2) duration and magnitude of the decline in value, (3) the financial condition of the issuer or issuers, (4) structure of the security, and (5) the intent to sell the security or whether it is more likely than not that the Company would be required to sell the security before its anticipated recovery in market value. At December 31, 2013, management performed its quarterly analysis of all securities with an unrealized loss and concluded no individual securities were other-than-temporarily impaired.

The gross gains and gross losses realized from sales of available for sale investment securities were as follows:

	December 31,

The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt, such as current financial information, historical payment experience, credit documentation, and current economic factors among other factors. This analysis is performed on a quarterly basis. The Company uses the following definitions for risk ratings:

• Grades 1, 2, and 3 – These grades include loans to borrowers with a continuous record of strong earnings, sound balance sheet condition and capitalization, ample liquidity with solid cash flow and whose management team has experience and depth within their industry.

• Grade 4 – This grade includes loans to borrowers with positive trends in profitability, satisfactory capitalization and balance sheet condition, and sufficient liquidity and cash flow.

• Grade 5 – This grade includes loans to borrowers that may display fluctuating trends in sales, profitability, capitalization, liquidity, and cash flow.

• Grade 6 – This grade includes loans to borrowers where an adverse change or perceived weakness has occurred, but may be correctable in the near future. Alternatively, this rating category may also include circumstances where the company is starting to reverse a negative trend or condition, or has recently been upgraded from a 7, 8, or 9 rating.

• Grade 7 – Watch credits are companies that have experienced financial setback of a nature that are not determined to be severe or influence ‘ongoing concern’ expectations. Borrowers within this category are expected to turnaround within a 12-month period of time. Although possible, no loss is anticipated, due to strong collateral and/or guarantor support.

• Grade 8 – Substandard credits will include those companies that are characterized by significant losses and sustained downward trends in balance sheet condition, liquidity, and cash flow. Repayment reliance may have shifted to secondary sources. Collateral exposure may exist and additional reserves may be warranted.

• Grade 9 – Doubtful credits include borrowers that may show deteriorating trends that are unlikely to be corrected. Collateral values may appear insufficient for full recovery, therefore requiring a partial charge-off, or debt renegotiation with the borrower. Borrower may have declared bankruptcy or bankruptcy is likely in the near term. All doubtful rated credits will be on non-accrual.

NOTE 8 - DERIVATIVE FINANCIAL INSTRUMENTS

The Company is a party to various derivative financial instruments that are used in the normal course of business to meet the needs of its clients and as part of its risk management activities. These instruments include interest rate swaps and option contracts and foreign exchange forward contracts. The Company does not enter into derivative financial instruments for trading or speculative purposes.

Using derivative instruments can involve assuming counterparty credit risk to varying degrees. Counterparty credit risk relates to the loss the Company could incur if a counterparty were to default on a derivative contract. Notional amounts of derivative financial instruments do not represent credit risk, and are not recorded in the consolidated balance sheet. The overall credit risk and exposure to individual counterparties is monitored. The Company does not anticipate nonperformance by any counterparties. The amount of counterparty credit exposure is the unrealized gains in excess of collateral pledged, if any, on such derivative contracts along with the value of foreign exchange forward contracts. At December 31, 2013, the Company had $1.0 million of counterparty credit exposure on derivatives. This counterparty risk is considered as part of underwriting and on-going monitoring policies. At December 31, 2013 and 2012, the Company had pledged cash of $1.0 million and $3.3 million, respectively, as collateral in connection with interest rate swap agreements.

93

Risk Management Instruments. The Company enters into certain derivative contracts to economically hedge state tax credits and certain loans.

• Economic hedge of state tax credits. In November 2008, the Company paid $2.1 million to enter into a series of interest rate caps in order to economically hedge changes in fair value of the State tax credits held for sale. In February 2010, the Company paid $0.8 million for an additional series of interest rate caps. See Note 20—Fair Value Measurements for further discussion of the fair value of the state tax credits.

The table below summarizes the notional amounts and fair values of the derivative instruments used to manage risk.

The securities are redeemable in whole or in part on or after their respective call dates. Mandatory redemption dates may be shortened if certain conditions are met. The securities are classified as subordinated debentures in the Company's consolidated balance sheets. Interest on the subordinated debentures held by the trusts is recorded as interest expense in the Company's consolidated statements of operations.

NOTE 16-REGULATORY MATTERS

Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios (set forth in the following table) of total and Tier 1 capital to risk-weighted assets, and of Tier 1 capital to average assets.

NOTE 17 - COMPENSATION PLANS

The Company has adopted share-based compensation plans to reward and provide long-term incentive for directors and key employees of the Company. These plans provide for the granting of stock, stock options, stock-settled stock appreciation rights ("SSARs"), and restricted stock units (“RSUs”), as designated by the Company's Board of Directors upon the recommendation of the Compensation Committee. The Company uses authorized and unissued shares to satisfy share award exercises. There were no options or SSARs granted in 2013. At December 31, 2013, there were 978,660 shares available for grant under the various share-based compensation plans.

Total share-based compensation expense that was charged against income was $5.0 million, $2.5 million, and $1.8 million for the years ended December 31, 2013, 2012, and 2011 respectively. The total income tax benefit/(expense) recognized in additional paid in capital for share-based compensation arrangements was $0.2 million, $0.1 million, and $(0.1) million for the years ended December 31, 2013, 2012, and 2011, respectively.

Employee Stock Options and Stock-settled Stock Appreciation Rights

In determining compensation cost for stock options and SSARs, the Black-Scholes option-pricing model is used to estimate the fair value on date of grant. The Black-Scholes model is a closed-end model that uses the assumptions in the following table. There were no grants of employee stock options or SSARs during the years ended December 31, 2013, 2012, or 2011.

101

Stock options have been granted to key employees with exercise prices equal to the market price of the Company's common stock at the date of grant and 10-year contractual terms. Stock options have a vesting schedule of three to five years. The SSARs are subject to continued employment, have a 10-year contractual term and vest ratably over five years. Neither stock options nor SSARs carry voting or dividend rights until exercised. At December 31, 2013, there was $152,671 of total unrecognized compensation cost related to SSARs which is expected to be recognized over a weighted average period of 1.59 years. Various information related to the stock options and SSARs is shown below.

Restricted Stock Units (“RSU”)

As part of a long-term incentive plan, the Company awards nonvested stock, in the form of RSUs to employees. RSUs are subject to continued employment and vest ratably over three to five years. RSUs do not carry voting or dividend rights until vested. Sales of the units are restricted prior to vesting. Various information related to the RSUs is shown below.

Stock Plan for Non-Management Directors

In 2006, the Company adopted a Stock Plan for Non-Management Directors, which provides for issuing 100,000 shares of common stock to non-employee directors as compensation in lieu of cash. In 2012, an amendment to the plan was approved by the shareholders allowing a total of up to 200,000 shares to be awarded. At December 31, 2013, there were 83,764 shares of stock available for issuance under the Stock Plan for Non-Management Directors. Shares are issued twice a year and compensation expense is recorded as the shares are earned, therefore, there is no unrecognized compensation cost related to this plan. In 2013, the Company issued 16,990 shares of stock at a weighted average fair value of $15.40 per share. In 2012, the Company issued 18,410 shares of stock at a weighted average fair value of $14.00 per share. In 2011, the Company issued 19,830 shares of stock at a weighted average fair value of $12.90 per share. The Company recognized $0.3 million of stock-based compensation expense for the shares issued to the directors in 2013, 2012, and 2011, respectively.

Employee Stock Issuance

Restricted stock was issued to certain key employees as part of their compensation. The restricted stock may be in the form of a one-time award or paid in pro rata installments. The stock is restricted for at least 2 years and upon issuance may be fully vested or vest over 5 years. The Company recognized $0.6 million, $0.2 million, and $30,000 of stock-based compensation expense for the shares issued to the employees in 2013, 2012, and 2011, respectively. The Company issued 37,943, 71,899, and 6,724 shares in 2013, 2012, and 2011, respectively.

In 2011, 2012 and 2013, the Company entered into long-term incentive agreements with certain key employees. These open awards are conditioned on certain performance criteria and market criteria measured against a group of peer banks over a 3 year period for each grant. The amount of the awards are determined at the end of the 3 year vesting period. In February 2014, the Company issued 146,700 shares to employees upon completion of the 2011-2013 performance cycle. The 2012 and 2013 grants are not yet determinable. The Company recorded $3.2 million, $1.3 million and $0 of stock-based compensation expense for these awards during 2013, 2012 and 2011, respectively.

401(k) plans

The Company has a 401(k) savings plan which covers substantially all full-time employees over the age of 21. The amount charged to expense for the Company's contributions to the plan was $1.2 million, $1.2 million and $1.1 million for 2013, 2012, and 2011, respectively.

The amount of tax credits and other tax benefits from low-income housing tax credit ("LIHTC") investments recognized during the year were $1.1 million, $1.1 million, and $1.0 million during the years ended December 31, 2013, 2012, and 2011, respectively. The amount recognized as a component of income tax expense per the table above was $0.2 million, $0.2 million, and $0.2 million for the years ended December 31, 2013, 2012, and 2011, respectively. As of December 31, 2013 and 2012, the carrying value of the investments related to low-income housing tax credits was $4.2 million and $5.1 million, respectively. No impairment losses have been recognized from forfeiture or ineligibility of tax credits or other circumstances during the life of any of the investments. As of December 31, 2013, the Company has future capital commitments of $0.6 million related to low-income housing tax credit investments. The capital commitments are expected to be called between the years 2014 - 2024.

104

A net deferred income tax asset of $39.4 million and $21.8 million is included in other assets in the consolidated balance sheets at December 31, 2013 and 2012, respectively. The tax effect of temporary differences that gave rise to significant portions of the deferred tax assets and deferred tax liabilities is as follows:

Net deferred tax asset	$	39,408	$	21,779

A valuation allowance is provided on deferred tax assets when it is more likely than not that some portion of the assets will not be realized. The Company did not have any valuation allowances for federal income taxes as of December 31, 2013 or 2012. Management believes it is more likely than not that the results of future operations will generate sufficient federal taxable income to realize the deferred federal tax assets. Due to positive evidence about the Company's ability to generate taxable income in the future, the Company reversed its state valuation allowance in 2012. Accordingly, the Company had no state tax valuation allowance as of December 31, 2013 and 2012.

The Company and its subsidiaries file income tax returns in the federal jurisdiction and in nine states. With few exceptions, the Company is no longer subject to federal, state or local income tax audits by tax authorities for years before 2010. The Company is not currently under audit by any taxing jurisdiction.

The Company recognizes interest and penalties related to uncertain tax positions in income tax expense and classifies such interest and penalties in the liability for unrecognized tax benefits. The amounts accrued for interest and penalties as of December 31, 2013, 2012, and 2011 were not significant.

As of December 31, 2013, the gross amount of unrecognized tax benefits was $1.3 million and the total amount of net unrecognized tax benefits that would impact the effective tax rate, if recognized, was $0.8 million. As of December 31, 2012 and 2011, the total amount of the net unrecognized tax benefits that would impact the effective tax rate, if recognized, was $0.8 million and $0.7 million, respectively. The Company believes it is reasonably possible that the gross amount of unrecognized benefits will be reduced by approximately $0.3 million as a result of a lapse of statute of limitations in the next 12 months.

NOTE 19 - COMMITMENTS AND CONTINGENCIES

The Company issues financial instruments with off balance sheet risk in the normal course of the business of meeting the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. These instruments may involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the consolidated balance sheets.

The Company’s extent of involvement and maximum potential exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of these instruments.

The Company uses the same credit policies in making commitments and conditional obligations as it does for financial instruments included on its consolidated balance sheets. At December 31, 2013, there were $79,000 of unadvanced commitments on impaired loans. Other liabilities include approximately $150,000 for estimated losses attributable to the unadvanced commitments. At December 31, 2012, there were $775,000 of unadvanced commitments on impaired loans. Other liabilities include approximately $124,000 for estimated losses attributable to the unadvanced commitments.

The contractual amounts of off-balance-sheet financial instruments as of December 31, 2013, and December 31, 2012, are as follows:

(in thousands)	December 31, 2013		December 31, 2012
Commitments to extend credit	$	804,420	$	722,325
Standby letters of credit	44,376		42,561

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments usually have fixed expiration dates or other termination clauses, may have significant usage restrictions, and may require payment of a fee. Of the total commitments to extend credit at December 31, 2013, and December 31, 2012, approximately $50.3 million and $50.7 million, respectively, represent fixed rate loan commitments. Since certain of the commitments may expire without being drawn upon or may be revoked, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the borrower. Collateral held varies, but may include accounts receivable, inventory, premises and equipment, and real estate.

Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. These standby letters of credit are issued to support contractual obligations of the Company’s customers. The credit risk involved in issuing letters of credit is essentially the same as the risk involved in extending

106

loans to customers. The approximate remaining term of standby letters of credit range from 1 month to 5 years at December 31, 2013.

Contingencies

See Note 15 - Litigation and Other Claimsfor further discussion of our current contingencies.

NOTE 20 - FAIR VALUE MEASUREMENTS

The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. In estimating fair value, the Company utilizes valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. Such valuation techniques are consistently applied. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. ASC Topic 820, “Fair Value Measurements and Disclosures,” establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

• Level 1 Inputs - Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

• Level 2 Inputs - Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means.

• Level 3 Inputs - Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity's own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.

107

The following table summarizes financial instruments measured at fair value on a recurring basis as of December 31, 2013 and 2012, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value.

• Securities available for sale. Securities classified as available for sale are reported at fair value utilizing Level 2 and Level 3 inputs. Fair values for Level 2 securities are based upon dealer quotes, market spreads, the U.S. Treasury yield curve, trade execution data, market consensus prepayment speeds, credit information and the bond's terms and conditions at the security level. At December 31, 2013, Level 3 securities available for sale consist primarily of three Auction Rate Securities that are valued based on the securities' estimated cash flows, yields of comparable securities, and live trading levels.

108

• Portfolio Loans. Certain fixed rate portfolio loans are accounted for as trading instruments and reported at fair value. Fair value on these loans is determined using a third party valuation model with observable Level 2 market data inputs.

• State tax credits held for sale. At December 31, 2013, of the $48.5 million of state tax credits held for sale on the condensed consolidated balance sheet, approximately $16.5 million were carried at fair value. The remaining $32.0 million of state tax credits were accounted for at cost. The Company elected not to account for the state tax credits purchased in 2012 and 2013 at fair value in order to limit the volatility of the fair value changes in our consolidated statements of operations.

The Company is not aware of an active market that exists for the 10-year streams of state tax credit financial instruments. However, the Company’s principal market for these tax credits consists of Missouri state residents who buy these credits and local and regional accounting firms who broker them. As such, the Company employed a discounted cash flow analysis (income approach) to determine the fair value.

The fair value measurement is calculated using an internal valuation model with market data including discounted cash flows based upon the terms and conditions of the tax credits. If the underlying project remains in compliance with the various federal and state rules governing the tax credit program, each project will generate about 10 years of tax credits. The inputs to the discounted cash flow calculation include: the amount of tax credits generated each year, the anticipated sale price of the tax credit, the timing of the sale and a discount rate. The discount rate is estimated using the LIBOR swap curve at a point equal to the remaining life in years of credits plus a 205 basis point spread. With the exception of the discount rate, the other inputs to the fair value calculation are observable and readily available. The discount rate is considered a Level 3 input because it is an “unobservable input” and is based on the Company’s assumptions. An increase in the discount rate utilized would generally result in a lower estimated fair value of the tax credits. Alternatively, a decrease in the discount rate utilized would generally result in a higher estimated fair value of the tax credits. Given the significance of this input to the fair value calculation, the state tax credit assets are reported as Level 3 assets.

Economically, the Company equates the state tax credits to a fixed rate loan. After considering various risks, such as credit risk, compliance risk, and recapture risk, management concluded the state tax credits are equivalent to a fixed rate loan priced at Prime minus 75 basis points. When pricing a fixed rate loan, most banks utilize the Prime-based swap curve, which is based on the LIBOR swap curve plus a prime equivalent spread of 265 to 285 basis points depending on market pricing and the maturity of the underlying loan. The Prime-based swap curve is available daily on Bloomberg or other national pricing services. As a result, at December 31, 2013 and 2012, management concluded the spread of 205 basis points to the LIBOR curve should be utilized in the fair value calculation.

At December 31, 2013, the discount rates utilized in our state tax credits fair value calculation ranged from 2.30% to 4.82%. Resulting changes in the fair value of the state tax credits held for sale decreased Gain on state tax credits, net in the consolidated statement of operations by $1.3 million for the year ended December 31, 2013.

• Derivatives. Derivatives are reported at fair value utilizing Level 2 inputs. The Company obtains counterparty quotations to value its interest rate swaps and caps. In addition, the Company validates the counterparty quotations with third party valuation sources. Derivatives with negative fair values are included in Other liabilities in the consolidated balance sheets. Derivatives with positive fair value are included in Other assets in the consolidated balance sheets.

109

Level 3 financial instruments

The following table presents the changes in Level 3 financial instruments measured at fair value on a recurring basis as of December 31, 2013 and 2012.

• Purchases, sales, issuances and settlements. There were no Level 3 purchases during the year ended December 31, 2013.

• Transfers in and/or out of Level 3. The transfer out of Level 3 is related to a newly issued mortgage-backed security purchased in the fourth quarter of 2011 which was originally priced using Level 3 assumptions. In the first quarter of 2012, a third party pricing service, utilizing Level 2 assumptions, became available as more data was available on the new security.

Fair value on a non-recurring basis

Certain financial assets and financial liabilities are measured at fair value on a non-recurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment).

• Impaired loans. Impaired loans are included as Portfolio loans on the Company's consolidated balance sheets with amounts specifically reserved for credit impairment in the Allowance for loan losses. On a quarterly basis, fair value adjustments are recorded on impaired loans to account for (1) partial write-downs that are based on the current appraised or market-quoted value of the underlying collateral or (2) the full charge-off of the loan carrying value. In some cases, the properties for which market quotes or appraised values have been obtained are located in areas where comparable sales data is limited, outdated, or unavailable. In addition, the Company may adjust the valuations based on other relevant market conditions or information. Accordingly, fair value estimates, including those obtained from real estate brokers or other third-party consultants, for collateral-dependent impaired loans are classified in Level 3 of the valuation hierarchy.

• Other Real Estate. These assets are reported at the lower of the loan carrying amount at foreclosure or fair value. Fair value is based on third party appraisals of each property and the Company's judgment of other relevant market conditions. These are considered Level 3 inputs.

The following table presents financial instruments and non-financial assets measured at fair value on a non-recurring basis as of December 31, 2013 and 2012.

(1) The amounts represent only balances measured at fair value during the period and still held as of the reporting date.

Impaired loans are reported at the fair value of the underlying collateral. Fair values for impaired loans are obtained from current appraisals by qualified licensed appraisers or independent valuation specialists. Other real estate owned is adjusted to fair value upon foreclosure of the underlying loan. Subsequently, foreclosed assets are carried at the

111

lower of carrying value or fair value less costs to sell. Fair value of other real estate is based upon the current appraised values of the properties as determined by qualified licensed appraisers and the Company’s judgment of other relevant market conditions. Certain state tax credits are reported at cost.

The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practical to estimate such value:

Cash, Federal funds sold, and other short-term instruments

For cash and due from banks, federal funds purchased, interest-bearing deposits, and accrued interest receivable (payable), the carrying amount is a reasonable estimate of fair value, as such instruments reprice in a short time period (Level 1).

Securities available for sale

The Company obtains fair value measurements for available for sale debt instruments from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond's terms and conditions (Level 2).

Other investments

Other investments, which primarily consists of membership stock in the FHLB, is reported at cost, which approximates fair value (Level 2).

Loans held for sale

These loans consist of mortgages that sold on the secondary market generally within three months of origination. They are reported at cost, which approximates fair value (Level 2).

113

Portfolio loans, net

The fair value of adjustable-rate loans approximates cost. The fair value of fixed-rate loans is estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers for the same remaining maturities. The fair value of the acquired loans are based on the present value of expected future cash flows (Level 3). The method of estimating fair value does not incorporate the exit-price concept of fair value prescribed by ASC Topic 820.

State tax credits held for sale

The fair value of state tax credits held for sale is calculated using an internal valuation model with unobservable market data as discussed in further detail above (Level 3).

Derivative financial instruments

The fair value of derivative financial instruments is based on quoted market prices by the counterparty and verified by the Company using public pricing information (Level 2).

Deposits

The fair value of demand deposits, interest-bearing transaction accounts, money market accounts and savings deposits is the amount payable on demand at the reporting date (Level 1). The fair value of fixed-maturity certificates of deposit is estimated by discounting the future cash flows using the rates currently offered for deposits of similar remaining maturities (Level 3).

Subordinated debentures

Fair value of subordinated debentures is based on discounting the future cash flows using rates currently offered for financial instruments of similar remaining maturities (Level 2).

Federal Home Loan Bank advances

The fair value of the FHLB advances is based on the discounted value of contractual cash flows. The discount rate is estimated using current rates on borrowed money with similar remaining maturities (Level 2).

Other borrowed funds

Other borrowed funds include customer repurchase agreements, federal funds purchased, notes payable, and secured borrowings related to loan participations. The fair value of federal funds purchased, customer repurchase agreements and notes payable are assumed to be equal to their carrying amount since they have an adjustable interest rate (Level 2).

Commitments to extend credit and standby letters of credit

The fair value of commitments to extend credit and standby letters of credit are estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements, the likelihood of the counterparties drawing on such financial instruments, and the present creditworthiness of such counterparties (Level 2). The Company believes such commitments have been made on terms which are competitive in the markets in which it operates; however, no premium or discount is offered thereon and accordingly, the Company has not assigned a value to such instruments for purposes of this disclosure.

Limitations

Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates are subjective in nature and involve uncertainties and matters of significant judgment, and therefore, cannot be determined with precision. Such estimates include the valuation of loans, goodwill, intangible assets, and other long-lived assets, along with assumptions used in the calculation of income taxes, among others. These estimates and assumptions are based on management's best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. We adjust such estimates and assumptions when facts and circumstances dictate. Decreasing real estate values, illiquid credit markets, volatile equity markets, and declines in consumer spending have combined to increase the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual

114

results could differ significantly from these estimates. Changes in estimates resulting from continuing changes in the economic environment will be reflected in the financial statement in future periods. In addition, these estimates do not reflect any premium or discount that could result from offering for sale at one time the Company's entire holdings of a particular financial instrument. Fair value estimates are based on existing on-balance and off-balance-sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in many of the estimates.

NOTE 21 - SEGMENT REPORTING

The Company has two primary operating segments, Banking and Wealth Management, which are delineated by the products and services that each segment offers. The segments are evaluated separately on their individual performance, as well as their contribution to the Company as a whole.

The Banking operating segment consists of a full-service commercial bank, with locations in St. Louis, Kansas City, and Phoenix. The majority of the Company’s assets and income result from the Banking segment. All banking locations have the same product and service offerings, have similar types and classes of customers and utilize similar service delivery methods. Pricing guidelines and operating policies for products and services are the same across all regions.

The Banking operating segment also includes activities surrounding the assets acquired under FDIC loss share agreements.

The Wealth Management segment includes our Trust division and the state tax credit brokerage activities. The Trust division provides estate planning, investment management, and retirement planning as well as strategic planning and management succession issues. State tax credits are part of a fee initiative designed to augment the Company’s wealth management segment and banking lines of business.

The Company's Corporate and Intercompany activities represent the elimination of items between segments as well as Corporate related items that Management feels are not allocable to either of the two respective segments.

The financial information for each business segment reflects that information which is specifically identifiable or which is allocated based on an internal allocation method. There were no material intersegment revenues among the two segments. Management periodically makes changes to methods of assigning costs and income to its business segments to better reflect operating results. When appropriate, these changes are reflected in prior year information presented below.

NOTE 24-NEW AUTHORITATIVE ACCOUNTING GUIDANCE

FASB ASU 2013-01, "Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities"On January 31, 2013, the FASB issued ASU 2013-01 which provides scope clarifications related to the previously issued ASU 2011-11. These ASU's provide new requirements for disclosures about instruments and transactions eligible for offset in the statement of financial position, as well as instruments and transactions subject to an agreement similar to a master netting arrangement. The amendments in these updates are effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. This ASU did not have a material impact on the Company's consolidated financial statements as it does not have any material assets or liabilities that are offset as discussed in the standard.

FASB ASU 2013-02, "Comprehensive Income (Topic 220)"In February 2013, the FASB issued ASU 2013-02 requiring new disclosures about reclassifications from accumulated other comprehensive loss to net income. These disclosures may be presented on the face of the statements or in the notes to the consolidated financial statements. This ASU is effective for fiscal years beginning after December 15, 2012. This ASU did not have a material impact on the consolidated financial statements. We have adopted this ASU and revised our disclosures, as seen in the Statement of Comprehensive Income and in Note 1 - Summary of Significant Accounting Policies.

FASB ASU 2014-01, "Investments - Equity Method and Joint Ventures (Topic 323) Accounting for Investments in Qualified Affordable Housing Projects" In January 2014 the FASB issued ASU 2014-01 which revised the accounting for investments in qualified affordable housing projects. The ASU modifies the conditions that must be met to present the pretax effects and related tax benefits of such investments as a component of income taxes ("net" within income tax expense). This ASU is effective for annual periods beginning after December 15, 2013 with early adoption permitted. The Company elected to early adopt this ASU and therefore revised its Consolidated Statements of Operations for all periods presented prior to the year ended December 31, 2013. The adoption of the ASU moved the amortization expense of its investment basis in the related investments to Income Tax Expense from Other Noninterest Expense. This resulted in a $0.9 million increase in Income Tax Expense and a corresponding decrease in Other Noninterest Expense for the years ended December 31, 2012 and 2011, respectively.

ITEM 9: CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

None.

ITEM 9A: CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, the “Act”) as of December 31, 2013. Based upon this evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that as of December 31, 2013, such disclosure controls and procedures were effective to ensure that information required to be disclosed by the Company in the reports it files or submits under the Act is accumulated and communicated to the Company’s management (including the Chief Executive Officer and Chief Financial Officer) to allow timely decisions regarding required disclosure, and is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

Management's Assessment of Internal Control Over Financial Reporting

Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(e) and 15(d)-15(e) under the Securities Exchange Act of 1934, as amended, the “Act”). The Company’s internal control system is a process designed to provide reasonable assurance to the Company’s management and Board of Directors regarding the preparation and fair presentation of published financial statements.

The Company’s internal control over financial reporting includes policies and procedures that pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect transactions and dispositions of assets; provide reasonable assurances that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the United States of America, and that receipts and expenditures are being made only in accordance with authorizations of management and the directors of the Company; and provide reasonable assurance regarding prevention or untimely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the Company’s financial statements.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial reporting. Further, because of changes in conditions, the effectiveness of any system of internal control may vary over time. The design of any internal control system also factors in resource constraints and consideration for the benefit of the control relative to the cost of implementing the control. Because of these inherent limitations in any system of internal control, management cannot provide absolute assurance that all control issues and instances of fraud within the Company have been detected.

Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2013. In making this assessment, management used the criteria set forth by the 1992 Committee of Sponsoring Organizations of the Treadway Commission in Internal Control - Integrated Framework. Management has concluded that the Company maintained an effective system of internal control over financial reporting based on these criteria as of December 31, 2013.

The Company’s independent registered public accounting firm, Deloitte & Touche LLP, who audited the consolidated financial statements, has issued an audit report on the Company’s internal control over financial reporting as of December 31, 2013, and it is included herein.

Changes in Internal Control Over Financial Reporting

There have been no changes in the Company’s internal control over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f) under the Act) that occurred during the Company’s quarter ended December 31, 2013 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

(ii)An amount equal to any annual cash Targeted Incentives for the year in which such termination occurs as though all “target levels” of performance for such year are fully and completely achieved multiplied by two (2).

6.409A. The following provisions shall apply notwithstanding any other provisions herein to the contrary:

6.1Separation From Service. Any amount that (i) is payable upon termination of Executive’s employment with the Company under any provision of this Agreement, and (ii) is subject to the requirements of Section 409A of the Internal Revenue Code of 1986, as amended (“Section 409A”), shall not be paid unless and until the Executive has Separated from Service. As used in this Agreement, the terms “Separated from Service” and “Separation from Service” shall have the meaning specified in Treasury Regulation Section 1.409A-1(h).

6.2Specified Employee. If Executive is a “specified employee” (within the meaning of Section 409A) of Company at the time of his termination of employment and if payment of severance compensation to the Executive is on account of an “involuntary separation from service” (as defined in Treasury Regulation Section 1.409A-1(n)), Executive shall be paid such severance compensation during the six (6) month period immediately following the date of his Separation from Service as otherwise provided under Section 5 for such six -month period except that the total amount of such payments shall not exceed the lesser of the amount specified under (i) Treasury Regulation Section 1.409A-1(9)(iii)(A)(1) or (ii) Treasury Regulation Section 1.409A-1(9)(iii)(A)(2). To the extent such amounts otherwise payable during such six-month period exceed the amounts payable under the immediately preceding sentence, such excess amounts shall not be paid during such six-month period, but instead shall be paid in a single sum on the first regular payroll date of Company immediately following the six (6) month anniversary of the date of Executive’s Separation from Service. If Executive is a specified employee and Executive’s Separation from Service is not an involuntary separation from service as defined in Treasury Regulation Section 1.409A-1(n), then any severance compensation and any other amount due to Executive under this Agreement that is subject to Section 409A and that would otherwise have been paid during the six (6) month period immediately following the date of Executive’s Separation from Service shall be paid in a single sum on the first payroll date of Company immediately following the six month anniversary of Executive’s Separation from Service. Amounts, the payment of which are deferred under this Section, shall be increased by interest at the prime rate as of the date of Executive’s Separation from Service as published in the Wall Street Journal from the date such amounts would have been paid but for this provision and such accumulated interest shall also be paid to the Executive on the first payroll date of Company immediately following the six month anniversary of Executive’s Separation from Service.

Notwithstanding the provisions of this Section 6, the Company has no responsibility or obligation to Executive with respect to any tax that may be incurred by Executive pursuant to Section 409A.

6.3Savings Clause. All payments under the Agreement are intended to be exempt from Section 409A as short-term deferrals. In the event that any provision of the Agreement is deemed to be subject to Section 409A, the Company shall operate the Agreement in accordance with the

requirements set forth in Section 409A. If any provision of the Agreement does not comply with the requirements of Section 409A, the Company, in exercise of its sole discretion and without consent of the Executive, may amend or modify the Agreement in any manner to the extent necessary to meet the requirements of Section 409A.

7.Death of Executive. In the event Executive dies before amounts are paid to him under this Agreement, such amounts shall be paid to his designed beneficiary of beneficiaries, or if there are no designated beneficiary or beneficiaries, to his estate.

8.Confidentiality; Non-Disparagement.

8.1Executive agrees to hold in strict confidence and not disclose all non-public information concerning any matters affecting or relating to the business of the Company, its Subsidiaries and Affiliates, including without limiting the generality of the foregoing non-public information concerning their manner of operation, business or other plans, data bases, marketing programs, protocols, processes, computer programs, client lists, marketing information and analyses, operating policies or manuals or other data (the “Confidential Information”). Executive agrees that he will not, directly or indirectly, use any Confidential Information for the benefit of any person, business, legal entity other than the Company or disclose or communicate any of the Confidential Information in any manner whatsoever other than to the directors, officers, employees, agents and representatives of the Company who need to know such information, who shall be informed by Executive of the confidential nature of the Confidential Information and directed by Executive to treat the Confidential Information confidentially. Upon the Company’s request, Executive shall return all information furnished to him related to the business of the Company without retaining any copies in electronic or other form. The above limitations on use and disclosure shall not apply to information which Executive can demonstrate: (a) was known to Executive before receipt thereof from the Company; (b) is learned by Executive from a third party entitled to disclose it; or (c) becomes known publicly other than through Executive; (d) is disclosed by Executive upon authority of the Board or any committee of the Board; (e) is disclosed pursuant to any legal requirement or (f) is disclosed pursuant to any agreement to which the Company or any of its Subsidiaries or Affiliates is a party. The parties hereto stipulate that all such information is material and confidential and gravely affects the effective and successful conduct of the business of the Company and the Company’s goodwill, and that any breach of the terms of this Section 8 shall be a material breach of this Agreement.

8.2Executive further agrees that, during the Employment Term and thereafter (regardless of the reason for such termination), Executive will not make any disparaging or derogatory statement, oral or written, to any third party which is or is likely to be materially detrimental to the goodwill of the Company or any of its Subsidiaries or Affiliates. Nothing herein shall prevent Executive from testifying truthfully in connection with any litigation, arbitration or administrative proceeding.

9.Use of Proprietary Information. Executive recognizes that the Company possesses a proprietary interest in all of the Confidential Information and has the exclusive right and privilege to use, protect by copyright, patent or trademark, manufacture or otherwise exploit the processes, ideas and concepts described therein to the exclusion of Executive, except as otherwise agreed between the Company and Executive in writing. Executive expressly agrees that any products, inventions, discoveries or improvements made by Executive, his agents or affiliates, during the Employment Term, based on or arising out of the Confidential Information shall be the property of and inure to the exclusive benefit of the Company. Executive further agrees that any and all products, inventions, discoveries or improvements developed by Executive (whether or not able to be protected by copyright, patent or trademark) in the scope of his employment, or involving the use of the Company’s time, materials or other resources, shall be promptly disclosed to the Company and shall become the exclusive property of the Company. Upon any termination of Executive’s employment or engagement with the Company, Executive shall immediately return all Confidential Information (and all tangible embodiments thereof) possessed by Executive to the Company.

10.Restrictive Covenants.

10.1Non-Competition. Because of Executive’s unique and specialized position within Company and Executive’s access to and familiarity with Company’s Confidential business methodologies, Executive agrees that, during the Employment Term and for a period of one year following a termination of Executive’s employment for any reason (the “Non-Compete Period”), Executive shall not, without the prior written consent of the Company, directly or indirectly, own, manage, operate, control, be connected with as an officer, employee, partner, consultant or otherwise, or otherwise engage or participate in (except as an employee of the Company, or its Affiliates) any Person engaged in the operation, ownership or management of a bank, trust company, or bank holding company within the Metropolitan Statistical Areas of St. Louis, Kansas City, Phoenix, Arizona or any other city in which the Company or any of its Affiliates has an office at the time of such termination. Notwithstanding the foregoing, (a) Executive’s employment during the Non-Compete Period by an entity that engages in the operation or management of a bank or trust company in addition to other business services shall not, in and of itself, be a violation of the foregoing provided that Executive is in no way directly or indirectly involved in (i) the management or operation of such bank or trust company or (ii) marketing or sales of banking or trust services; and (b) the ownership by Executive of less than 1% of any class of the outstanding capital stock of any corporation conducting such a competitive business which is regularly traded on a national securities exchange or in the over-the-counter market shall not be a violation of the foregoing covenant.

10.2Non-Solicitation.

(a)During the Employment Term and continuing during the Non-Compete Period, Executive shall not, except on behalf of or with the prior written consent of the Company, directly or indirectly, whether alone or in association, or combination with any other Person, or as an officer, director, shareholder, member, manager, employee, agent, independent contractor, consultant, advisor, joint venturer, partner or otherwise and whether or not for pecuniary benefit:

(i)solicit, take away, attempt to take away, divert, attempt to divert, engage in any of the Company’s Lines of Business (as defined below) with, contract with or in any way interfere with the relationship between any Protected Customer (as defined below) and the Company or its Affiliates.

(ii)(1) hire or employ any other employee of the Company, (2) entice, solicit, recruit or induce any other employee of the Company or its Affiliates to leave such employ or (3) otherwise interfere with the employment of any other employee of the Company or its Affiliates.

(b)Before Executive becomes employed by or becomes a consultant for a Person during the Non-Compete Period, Executive shall inform such Person of the provisions of this Section 10.2. Provided, however, that nothing contained herein shall prevent such Person employing Executive from continuing to provide services to any individual or other entity that was a customer of the Person prior to the date of the termination of Executive’s employment with the Company. Company may advise any third party with whom Executive may consider, establish or contract a relationship, including but not limited to an employment relationship of this Agreement and its terms, and the Company shall have no liability for so acting.

(c)For purposes of this Agreement, “Protected Customer” means any Person and its/his/her Affiliate (i) for whom the Company or any of its Affiliates has provided the Company’s lines of business, including without limitation wealth management, sales of tax credits, investment, banking, trust, insurance or other financial services provided by the Company or any of its Affiliates (collectively, “Company’s Lines of Business”) within the twenty-four month period prior to the termination of Executive’s employment with the Company or (ii) to whom the Executive on behalf of the Company or any of its Affiliates had made a proposal to provide any Company’s Lines of Business at any time within twelve (12) months preceding the termination of Executive’s employment with the Company.

10.3Saving Provision. The parties hereto agree that, in the event a court of competent jurisdiction shall determine that the geographical, durational or other elements of this covenant are unenforceable, such determination shall not render the entire covenant unenforceable. Rather, the excessive aspects of the covenant shall be reduced to the threshold which is enforceable, and the remaining aspects shall not be affected thereby. The parties intend that the restrictions of this Section 10 be given the construction that renders their provisions valid and enforceable to the maximum extent possible under applicable law.

10.4Equitable Relief. Executive acknowledges that the extent of damages to the Company from a breach of Sections 8, 9 and 10 of this Agreement would not be readily quantifiable or ascertainable, that monetary damages would be inadequate to make the Company whole in case of such a breach, and that there is not and would not be an adequate remedy at law for such a breach. Therefore, Executive specifically agrees that the Company is entitled to injunctive or other equitable relief (without any requirement to post any bond or other security) from a breach of Sections 8, 9 and 10 of this Agreement, and hereby waives and covenants not to assert against a prayer for such relief that there exists an adequate remedy at law, in monetary damages or otherwise.

10.5Tolling. Executive agrees that, in the event of a breach of any of the provisions of this Section 10, the time period specified in such provisions shall be extended by the number of days between the date of such breach and the date such breach is enjoined or other relief is granted to the Company by a court of competent jurisdiction. It is the intention of the parties that the Company shall enjoy the faithful performance by Executive of the covenants specified in this Section 10 for the full time periods specified herein.

10.6Reasonableness of Restrictive Covenants. Executive recognizes that as an employee and/or officer of the Company, (i) Executive has and will have substantial customer contacts, perform special and unique duties and services for the Company and acquire Confidential Information, (ii) the Confidential Information is the property of the Company and the use, misappropriation, or disclosure of the Confidential Information would constitute a breach of trust and could cause irreparable injury to the Company; and it is essential to the protection of the Company’s good will and to the maintenance of the Company’s competitive position that the Confidential Information be kept secret, and (iii) the Company has a valid, protectable right and business interest in preserving the relationships described in this Agreement. The Company and Executive further agree that but for Executive’s agreement to the provisions of Sections 8, 9 and 10 of this Agreement, Executive would not be eligible for continued employment by the Company on an “at will” basis and for no definite term and the Company would not make available or continue to make available to Executive the Confidential Information. Executive further agrees that: (A) the covenants and agreements contained herein are reasonable and necessary in order to protect the legitimate business interests of the Company and (B) the enforcement of such covenants would not unreasonably impair Executive’s ability to earn a livelihood.

11.Assignment. This Agreement is personal to Executive and shall not be assignable by him.

12.Entire Agreement. This Agreement and any agreements entered into after the date hereof under any of the Company’s benefit plans or compensation programs as described in Section 4 contain the complete agreement concerning the employment arrangement between the parties, including without limitation severance or termination pay, and shall, as of the Effective Date, supersede all other agreements or arrangements between the parties with regard to the subject matter hereof, including without limitation the Original Agreement.

13.Binding Agreement. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective heirs, legal representatives, successors and assigns. The obligations of the Company under this Agreement shall not be terminated by reason of any liquidation, dissolution, bankruptcy, cessation of business or similar event relating to the Company. This Agreement shall not be terminated by reason of any merger, consolidation or reorganization of the Company, but shall be binding upon and inure to the benefit of the surviving or resulting entity.

14.Modification. No waiver or modification of this Agreement or of any covenant, condition, or limitation herein contained shall be valid unless authorized by the Board and reduced to in writing and duly executed by the party to be charged therewith and no evidence of any waiver or modification shall be offered or received in evidence of any proceeding, arbitration, or litigation between the parties hereto arising out of or affecting this Agreement, or the rights or obligations of the parties thereunder, unless such waiver or modification is in writing, duly executed as aforesaid.

15.Severability. All agreements and covenants contained herein are severable, and in the event any of them shall be held to be invalid or unenforceable by any court of competent jurisdiction, this Agreement shall be interpreted as if such invalid agreements or covenants were not contained herein.

16.Manner of Giving Notice. All notices, requests and demands to or upon the respective parties hereto shall be sent by hand, certified mail, overnight air courier service, in each case with all applicable charges paid or otherwise provided for, addressed as follows, or to such other address as may hereafter be designated in writing by the respective parties hereto:

18.Headings. The headings have been inserted for convenience only and shall not be deemed to limit or otherwise affect any of the provisions of this Agreement.

19.Choice of Law. It is the intention of the parties hereto that this Agreement and the performance hereunder be construed in accordance with, under and pursuant to the laws of the State of Missouri without regard to the jurisdiction in which any action or special proceeding may be instituted.

20.Taxes. The Company may withhold from any payments made under this Agreement all applicable taxes, including but not limited to income, employment and social insurance taxes, as shall be required by law.

21.Voluntary Agreement; No Conflicts. Executive hereby represents and warrants to the Company that he is legally free to accept and perform his employment with the Company, that he has no obligation to any other person or entity that would affect or conflict with any of Executive’s obligations pursuant to such employment, and that the complete performance of the obligations pursuant to Executive’s employment will not violate any order or decree of any governmental or judicial body or contract by which Executive is bound. The Company will not request or require, and Executive agrees not to use, in the course of Executive’s employment with the Company, any information obtained in Executive’s employment with any previous employer to the extent that such use would violate any contract by which Executive is bound or any decision, law, regulation, order or decree of any governmental or judicial body.

22.Term of Agreement; Survival of Certain Provisions. The provisions of this Agreement shall survive in accordance with their respective terms. Without limiting the foregoing, the terms of Sections 8, 9 and 10 shall survive and remain in effect in accordance with their terms following any termination of this Agreement or the termination or expiration of the Employment Term for any reason whatsoever.

23.Venue. In the event of litigation arising out of or in connection with this Agreement, the parties hereto agree to submit to the jurisdiction of the state courts located in the County of St. Louis, Missouri.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Description of New Accounting Pronouncements Not yet Adopted [Text Block]

NOTE 24-NEW AUTHORITATIVE ACCOUNTING GUIDANCE

FASB ASU 2013-01, "Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities"On January 31, 2013, the FASB issued ASU 2013-01 which provides scope clarifications related to the previously issued ASU 2011-11. These ASU's provide new requirements for disclosures about instruments and transactions eligible for offset in the statement of financial position, as well as instruments and transactions subject to an agreement similar to a master netting arrangement. The amendments in these updates are effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. This ASU did not have a material impact on the Company's consolidated financial statements as it does not have any material assets or liabilities that are offset as discussed in the standard.

FASB ASU 2013-02, "Comprehensive Income (Topic 220)"In February 2013, the FASB issued ASU 2013-02 requiring new disclosures about reclassifications from accumulated other comprehensive loss to net income. These disclosures may be presented on the face of the statements or in the notes to the consolidated financial statements. This ASU is effective for fiscal years beginning after December 15, 2012. This ASU did not have a material impact on the consolidated financial statements. We have adopted this ASU and revised our disclosures, as seen in the Statement of Comprehensive Income and in Note 1 - Summary of Significant Accounting Policies.

FASB ASU 2014-01, "Investments - Equity Method and Joint Ventures (Topic 323) Accounting for Investments in Qualified Affordable Housing Projects" In January 2014 the FASB issued ASU 2014-01 which revised the accounting for investments in qualified affordable housing projects. The ASU modifies the conditions that must be met to present the pretax effects and related tax benefits of such investments as a component of income taxes ("net" within income tax expense). This ASU is effective for annual periods beginning after December 15, 2013 with early adoption permitted. The Company elected to early adopt this ASU and therefore revised its Consolidated Statements of Operations for all periods presented prior to the year ended December 31, 2013. The adoption of the ASU moved the amortization expense of its investment basis in the related investments to Income Tax Expense from Other Noninterest Expense. This resulted in a $0.9 million increase in Income Tax Expense and a corresponding decrease in Other Noninterest Expense for the years ended December 31, 2012 and 2011, respectively.

Regulatory Matters

REGULATORY MATTERS

Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios (set forth in the following table) of total and Tier 1 capital to risk-weighted assets, and of Tier 1 capital to average assets. Management believes, as of December 31, 2013 and 2012, that the Bank met all capital adequacy requirements to which it is subject.

As of December 31, 2013 and 2012, the Bank was categorized as “well capitalized” under the regulatory framework for prompt corrective action. To be categorized as “well capitalized” the Bank must maintain minimum total risk-based, Tier 1 risk-based and Tier 1 leverage ratios as set forth in the table.

The actual capital amounts and ratios are also presented in the table below:

Fair Value Disclosures [Abstract]

Fair Value Measurements

FAIR VALUE MEASUREMENTS

The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. In estimating fair value, the Company utilizes valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. Such valuation techniques are consistently applied. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. ASC Topic 820, “Fair Value Measurements and Disclosures,” establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

• Level 1 Inputs - Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

• Level 2 Inputs - Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means.

• Level 3 Inputs - Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity's own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.

Fair value on a recurring basis

The following table summarizes financial instruments measured at fair value on a recurring basis as of December 31, 2013 and 2012, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value.

• Securities available for sale. Securities classified as available for sale are reported at fair value utilizing Level 2 and Level 3 inputs. Fair values for Level 2 securities are based upon dealer quotes, market spreads, the U.S. Treasury yield curve, trade execution data, market consensus prepayment speeds, credit information and the bond's terms and conditions at the security level. At December 31, 2013, Level 3 securities available for sale consist primarily of three Auction Rate Securities that are valued based on the securities' estimated cash flows, yields of comparable securities, and live trading levels.

• Portfolio Loans. Certain fixed rate portfolio loans are accounted for as trading instruments and reported at fair value. Fair value on these loans is determined using a third party valuation model with observable Level 2 market data inputs.

• State tax credits held for sale. At December 31, 2013, of the $48.5 million of state tax credits held for sale on the condensed consolidated balance sheet, approximately $16.5 million were carried at fair value. The remaining $32.0 million of state tax credits were accounted for at cost. The Company elected not to account for the state tax credits purchased in 2012 and 2013 at fair value in order to limit the volatility of the fair value changes in our consolidated statements of operations.

The Company is not aware of an active market that exists for the 10-year streams of state tax credit financial instruments. However, the Company’s principal market for these tax credits consists of Missouri state residents who buy these credits and local and regional accounting firms who broker them. As such, the Company employed a discounted cash flow analysis (income approach) to determine the fair value.

The fair value measurement is calculated using an internal valuation model with market data including discounted cash flows based upon the terms and conditions of the tax credits. If the underlying project remains in compliance with the various federal and state rules governing the tax credit program, each project will generate about 10 years of tax credits. The inputs to the discounted cash flow calculation include: the amount of tax credits generated each year, the anticipated sale price of the tax credit, the timing of the sale and a discount rate. The discount rate is estimated using the LIBOR swap curve at a point equal to the remaining life in years of credits plus a 205 basis point spread. With the exception of the discount rate, the other inputs to the fair value calculation are observable and readily available. The discount rate is considered a Level 3 input because it is an “unobservable input” and is based on the Company’s assumptions. An increase in the discount rate utilized would generally result in a lower estimated fair value of the tax credits. Alternatively, a decrease in the discount rate utilized would generally result in a higher estimated fair value of the tax credits. Given the significance of this input to the fair value calculation, the state tax credit assets are reported as Level 3 assets.

Economically, the Company equates the state tax credits to a fixed rate loan. After considering various risks, such as credit risk, compliance risk, and recapture risk, management concluded the state tax credits are equivalent to a fixed rate loan priced at Prime minus 75 basis points. When pricing a fixed rate loan, most banks utilize the Prime-based swap curve, which is based on the LIBOR swap curve plus a prime equivalent spread of 265 to 285 basis points depending on market pricing and the maturity of the underlying loan. The Prime-based swap curve is available daily on Bloomberg or other national pricing services. As a result, at December 31, 2013 and 2012, management concluded the spread of 205 basis points to the LIBOR curve should be utilized in the fair value calculation.

At December 31, 2013, the discount rates utilized in our state tax credits fair value calculation ranged from 2.30% to 4.82%. Resulting changes in the fair value of the state tax credits held for sale decreased Gain on state tax credits, net in the consolidated statement of operations by $1.3 million for the year ended December 31, 2013.

• Derivatives. Derivatives are reported at fair value utilizing Level 2 inputs. The Company obtains counterparty quotations to value its interest rate swaps and caps. In addition, the Company validates the counterparty quotations with third party valuation sources. Derivatives with negative fair values are included in Other liabilities in the consolidated balance sheets. Derivatives with positive fair value are included in Other assets in the consolidated balance sheets.

Level 3 financial instruments

The following table presents the changes in Level 3 financial instruments measured at fair value on a recurring basis as of December 31, 2013 and 2012.

• Purchases, sales, issuances and settlements. There were no Level 3 purchases during the year ended December 31, 2013.

• Transfers in and/or out of Level 3. The transfer out of Level 3 is related to a newly issued mortgage-backed security purchased in the fourth quarter of 2011 which was originally priced using Level 3 assumptions. In the first quarter of 2012, a third party pricing service, utilizing Level 2 assumptions, became available as more data was available on the new security.

Fair value on a non-recurring basis

Certain financial assets and financial liabilities are measured at fair value on a non-recurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment).

• Impaired loans. Impaired loans are included as Portfolio loans on the Company's consolidated balance sheets with amounts specifically reserved for credit impairment in the Allowance for loan losses. On a quarterly basis, fair value adjustments are recorded on impaired loans to account for (1) partial write-downs that are based on the current appraised or market-quoted value of the underlying collateral or (2) the full charge-off of the loan carrying value. In some cases, the properties for which market quotes or appraised values have been obtained are located in areas where comparable sales data is limited, outdated, or unavailable. In addition, the Company may adjust the valuations based on other relevant market conditions or information. Accordingly, fair value estimates, including those obtained from real estate brokers or other third-party consultants, for collateral-dependent impaired loans are classified in Level 3 of the valuation hierarchy.

• Other Real Estate. These assets are reported at the lower of the loan carrying amount at foreclosure or fair value. Fair value is based on third party appraisals of each property and the Company's judgment of other relevant market conditions. These are considered Level 3 inputs.

The following table presents financial instruments and non-financial assets measured at fair value on a non-recurring basis as of December 31, 2013 and 2012.

(1) The amounts represent only balances measured at fair value during the period and still held as of the reporting date.

Impaired loans are reported at the fair value of the underlying collateral. Fair values for impaired loans are obtained from current appraisals by qualified licensed appraisers or independent valuation specialists. Other real estate owned is adjusted to fair value upon foreclosure of the underlying loan. Subsequently, foreclosed assets are carried at the lower of carrying value or fair value less costs to sell. Fair value of other real estate is based upon the current appraised values of the properties as determined by qualified licensed appraisers and the Company’s judgment of other relevant market conditions. Certain state tax credits are reported at cost.

The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practical to estimate such value:

Cash, Federal funds sold, and other short-term instruments

For cash and due from banks, federal funds purchased, interest-bearing deposits, and accrued interest receivable (payable), the carrying amount is a reasonable estimate of fair value, as such instruments reprice in a short time period (Level 1).

Securities available for sale

The Company obtains fair value measurements for available for sale debt instruments from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond's terms and conditions (Level 2).

Other investments

Other investments, which primarily consists of membership stock in the FHLB, is reported at cost, which approximates fair value (Level 2).

Loans held for sale

These loans consist of mortgages that sold on the secondary market generally within three months of origination. They are reported at cost, which approximates fair value (Level 2).

Portfolio loans, net

The fair value of adjustable-rate loans approximates cost. The fair value of fixed-rate loans is estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers for the same remaining maturities. The fair value of the acquired loans are based on the present value of expected future cash flows (Level 3). The method of estimating fair value does not incorporate the exit-price concept of fair value prescribed by ASC Topic 820.

State tax credits held for sale

The fair value of state tax credits held for sale is calculated using an internal valuation model with unobservable market data as discussed in further detail above (Level 3).

Derivative financial instruments

The fair value of derivative financial instruments is based on quoted market prices by the counterparty and verified by the Company using public pricing information (Level 2).

Deposits

The fair value of demand deposits, interest-bearing transaction accounts, money market accounts and savings deposits is the amount payable on demand at the reporting date (Level 1). The fair value of fixed-maturity certificates of deposit is estimated by discounting the future cash flows using the rates currently offered for deposits of similar remaining maturities (Level 3).

Subordinated debentures

Fair value of subordinated debentures is based on discounting the future cash flows using rates currently offered for financial instruments of similar remaining maturities (Level 2).

Federal Home Loan Bank advances

The fair value of the FHLB advances is based on the discounted value of contractual cash flows. The discount rate is estimated using current rates on borrowed money with similar remaining maturities (Level 2).

Other borrowed funds

Other borrowed funds include customer repurchase agreements, federal funds purchased, notes payable, and secured borrowings related to loan participations. The fair value of federal funds purchased, customer repurchase agreements and notes payable are assumed to be equal to their carrying amount since they have an adjustable interest rate (Level 2).

Commitments to extend credit and standby letters of credit

The fair value of commitments to extend credit and standby letters of credit are estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements, the likelihood of the counterparties drawing on such financial instruments, and the present creditworthiness of such counterparties (Level 2). The Company believes such commitments have been made on terms which are competitive in the markets in which it operates; however, no premium or discount is offered thereon and accordingly, the Company has not assigned a value to such instruments for purposes of this disclosure.

Limitations

Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates are subjective in nature and involve uncertainties and matters of significant judgment, and therefore, cannot be determined with precision. Such estimates include the valuation of loans, goodwill, intangible assets, and other long-lived assets, along with assumptions used in the calculation of income taxes, among others. These estimates and assumptions are based on management's best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. We adjust such estimates and assumptions when facts and circumstances dictate. Decreasing real estate values, illiquid credit markets, volatile equity markets, and declines in consumer spending have combined to increase the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in estimates resulting from continuing changes in the economic environment will be reflected in the financial statement in future periods. In addition, these estimates do not reflect any premium or discount that could result from offering for sale at one time the Company's entire holdings of a particular financial instrument. Fair value estimates are based on existing on-balance and off-balance-sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in many of the estimates.

Commitments and Contingencies

COMMITMENTS AND CONTINGENCIES

The Company issues financial instruments with off balance sheet risk in the normal course of the business of meeting the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. These instruments may involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the consolidated balance sheets.

The Company’s extent of involvement and maximum potential exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of these instruments.

The Company uses the same credit policies in making commitments and conditional obligations as it does for financial instruments included on its consolidated balance sheets. At December 31, 2013, there were $79,000 of unadvanced commitments on impaired loans. Other liabilities include approximately $150,000 for estimated losses attributable to the unadvanced commitments. At December 31, 2012, there were $775,000 of unadvanced commitments on impaired loans. Other liabilities include approximately $124,000 for estimated losses attributable to the unadvanced commitments.

The contractual amounts of off-balance-sheet financial instruments as of December 31, 2013, and December 31, 2012, are as follows:

(in thousands)	December 31, 2013		December 31, 2012
Commitments to extend credit	$	804,420	$	722,325
Standby letters of credit	44,376		42,561

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments usually have fixed expiration dates or other termination clauses, may have significant usage restrictions, and may require payment of a fee. Of the total commitments to extend credit at December 31, 2013, and December 31, 2012, approximately $50.3 million and $50.7 million, respectively, represent fixed rate loan commitments. Since certain of the commitments may expire without being drawn upon or may be revoked, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the borrower. Collateral held varies, but may include accounts receivable, inventory, premises and equipment, and real estate.

Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. These standby letters of credit are issued to support contractual obligations of the Company’s customers. The credit risk involved in issuing letters of credit is essentially the same as the risk involved in extending loans to customers. The approximate remaining term of standby letters of credit range from 1 month to 5 years at December 31, 2013.

Segment Reporting [Abstract]

Segment Reporting

NOTE 21 - SEGMENT REPORTING

The Company has two primary operating segments, Banking and Wealth Management, which are delineated by the products and services that each segment offers. The segments are evaluated separately on their individual performance, as well as their contribution to the Company as a whole.

The Banking operating segment consists of a full-service commercial bank, with locations in St. Louis, Kansas City, and Phoenix. The majority of the Company’s assets and income result from the Banking segment. All banking locations have the same product and service offerings, have similar types and classes of customers and utilize similar service delivery methods. Pricing guidelines and operating policies for products and services are the same across all regions.

The Banking operating segment also includes activities surrounding the assets acquired under FDIC loss share agreements.

The Wealth Management segment includes our Trust division and the state tax credit brokerage activities. The Trust division provides estate planning, investment management, and retirement planning as well as strategic planning and management succession issues. State tax credits are part of a fee initiative designed to augment the Company’s wealth management segment and banking lines of business.

The Company's Corporate and Intercompany activities represent the elimination of items between segments as well as Corporate related items that Management feels are not allocable to either of the two respective segments.

The financial information for each business segment reflects that information which is specifically identifiable or which is allocated based on an internal allocation method. There were no material intersegment revenues among the two segments. Management periodically makes changes to methods of assigning costs and income to its business segments to better reflect operating results. When appropriate, these changes are reflected in prior year information presented below.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

DERIVATIVE FINANCIAL INSTRUMENTS

The Company is a party to various derivative financial instruments that are used in the normal course of business to meet the needs of its clients and as part of its risk management activities. These instruments include interest rate swaps and option contracts and foreign exchange forward contracts. The Company does not enter into derivative financial instruments for trading or speculative purposes.

Using derivative instruments can involve assuming counterparty credit risk to varying degrees. Counterparty credit risk relates to the loss the Company could incur if a counterparty were to default on a derivative contract. Notional amounts of derivative financial instruments do not represent credit risk, and are not recorded in the consolidated balance sheet. The overall credit risk and exposure to individual counterparties is monitored. The Company does not anticipate nonperformance by any counterparties. The amount of counterparty credit exposure is the unrealized gains in excess of collateral pledged, if any, on such derivative contracts along with the value of foreign exchange forward contracts. At December 31, 2013, the Company had $1.0 million of counterparty credit exposure on derivatives. This counterparty risk is considered as part of underwriting and on-going monitoring policies. At December 31, 2013 and 2012, the Company had pledged cash of $1.0 million and $3.3 million, respectively, as collateral in connection with interest rate swap agreements.

Risk Management Instruments. The Company enters into certain derivative contracts to economically hedge state tax credits and certain loans.

• Economic hedge of state tax credits. In November 2008, the Company paid $2.1 million to enter into a series of interest rate caps in order to economically hedge changes in fair value of the State tax credits held for sale. In February 2010, the Company paid $0.8 million for an additional series of interest rate caps. See Note 20—Fair Value Measurements for further discussion of the fair value of the state tax credits.

The table below summarizes the notional amounts and fair values of the derivative instruments used to manage risk.

Acquisitions

ACQUISITIONS & DIVESTITURES

FDIC-Assisted Transactions

The PCI loans acquired were recorded at estimated fair value. As such, there was no allowance for credit losses established related to the acquired loans at the various acquisition dates and no carryover of the related allowance from the failed banks. The loans are accounted for in accordance with guidance for certain loans acquired in a transfer, when the loans have evidence of credit deterioration and it is probable at the date of acquisition that the acquirer will not collect all contractually required principal and interest payments. The difference between contractually required payments and the cash flows expected to be collected at acquisition is referred to as the non-accretable difference. Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent increases in cash flows result in a reversal of the provision for loan losses to the extent of prior charges and an adjustment in accretable yield, which will have a positive impact on interest income, prospectively.

In connection with each acquisition, the Bank also entered into a shared-loss agreement whereby the FDIC will reimburse the Bank for a percentage of all losses incurred on certain loans and other real estate covered under the agreement. The shared-loss agreements are subject to the servicing procedures as specified in the agreement with the FDIC. The shared-loss agreements applicable to single-family residential mortgage loans have terms of ten (10) years, while the shared-loss agreements applicable to all other Covered Assets have terms of five (5) years, while requiring the Bank to reimburse the FDIC for any recoveries of such shared losses for a period of eight (8) years.

The reimbursable losses from the FDIC were recorded at fair value as of the date of acquisition based on the present value of expected cash flows from the reimbursement of credit losses on the Covered Assets. These reimbursable losses, which are recorded as FDIC loss share receivable on the Consolidated Balance Sheets, are measured separately from the Covered Assets as the shared-loss agreement with the FDIC is not contractually embedded in or transferable with the Covered Assets. Reimbursements received from the FDIC for actual incurred losses will reduce the FDIC loss share receivable. Subsequent measurements of the remaining loss reimbursements under the shared-loss agreement are determined on the same basis as the Covered Assets. In certain circumstances, reductions to the expected losses on the Covered Assets will result in the amortization of the FDIC loss share receivable. Any amortization of the FDIC loss share receivable shall be limited to the lesser of the contractual terms of the shared-loss agreement and the remaining life of the Covered Assets. Additional expected losses, to the extent such expected losses result in a provision for loan losses, will increase the FDIC loss share receivable.

The Company has omitted certain pro forma financial information surrounding its FDIC-Assisted Transactions as allowed under Staff Accounting Bulletin 1K - Financial Statements of Acquired Troubled Financial Institutions as this information is not reasonably available.

The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt, such as current financial information, historical payment experience, credit documentation, and current economic factors among other factors. This analysis is performed on a quarterly basis. The Company uses the following definitions for risk ratings:

• Grades 1, 2, and 3 – These grades include loans to borrowers with a continuous record of strong earnings, sound balance sheet condition and capitalization, ample liquidity with solid cash flow and whose management team has experience and depth within their industry.

• Grade 4 – This grade includes loans to borrowers with positive trends in profitability, satisfactory capitalization and balance sheet condition, and sufficient liquidity and cash flow.

• Grade 5 – This grade includes loans to borrowers that may display fluctuating trends in sales, profitability, capitalization, liquidity, and cash flow.

• Grade 6 – This grade includes loans to borrowers where an adverse change or perceived weakness has occurred, but may be correctable in the near future. Alternatively, this rating category may also include circumstances where the company is starting to reverse a negative trend or condition, or has recently been upgraded from a 7, 8, or 9 rating.

• Grade 7 – Watch credits are companies that have experienced financial setback of a nature that are not determined to be severe or influence ‘ongoing concern’ expectations. Borrowers within this category are expected to turnaround within a 12-month period of time. Although possible, no loss is anticipated, due to strong collateral and/or guarantor support.

• Grade 8 – Substandard credits will include those companies that are characterized by significant losses and sustained downward trends in balance sheet condition, liquidity, and cash flow. Repayment reliance may have shifted to secondary sources. Collateral exposure may exist and additional reserves may be warranted.

• Grade 9 – Doubtful credits include borrowers that may show deteriorating trends that are unlikely to be corrected. Collateral values may appear insufficient for full recovery, therefore requiring a partial charge-off, or debt renegotiation with the borrower. Borrower may have declared bankruptcy or bankruptcy is likely in the near term. All doubtful rated credits will be on non-accrual.

At December 31, 2013, and December 31, 2012, there were no holdings of securities of any one issuer in an amount greater than 10% of shareholders’ equity, other than the U.S. Government agencies and sponsored enterprises. The agency mortgage-backed securities are all issued by U.S. Government-sponsored enterprises. Available for sale securities having a fair value of $270.1 million and $359.3 million at December 31, 2013, and December 31, 2012, respectively, were pledged as collateral to secure deposits of public institutions and for other purposes as required by law or contract provisions.

The amortized cost and estimated fair value of debt securities classified as available for sale at December 31, 2013, by contractual maturity, are shown below. Expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. The weighted average life of the mortgage-backed securities is approximately 5 years.

The unrealized losses at both December 31, 2013, and December 31, 2012, were primarily attributable to changes in market interest rates since the securities were purchased. Management systematically evaluates investment securities for other-than-temporary declines in fair value on a quarterly basis. This analysis requires management to consider various factors, which include among other considerations (1) the present value of the cash flows expected to be collected compared to the amortized cost of the security, (2) duration and magnitude of the decline in value, (3) the financial condition of the issuer or issuers, (4) structure of the security, and (5) the intent to sell the security or whether it is more likely than not that the Company would be required to sell the security before its anticipated recovery in market value. At December 31, 2013, management performed its quarterly analysis of all securities with an unrealized loss and concluded no individual securities were other-than-temporarily impaired.

The gross gains and gross losses realized from sales of available for sale investment securities were as follows:

	December 31,
(in thousands)	2013			2012			2011

Outstanding balances on PCI loans were $201.7 million and $301.2 million as of December 31, 2013, and December 31, 2012, respectively.

Due to continued favorable projections in expected cash flows, the Company now anticipates it will be required to pay the FDIC at the end of two of its loss share agreements. Accordingly, a contingent liability of $1.5 million has been recorded as of December 31, 2013 with $1.0 million of expense recorded through Other Noninterest expense for the year ended December 31, 2013.

Accounting Policies [Abstract]

Business and Consolidation

Enterprise Financial Services Corp and subsidiaries (the “Company” or “Enterprise”) is a financial holding company that provides a full range of banking and wealth management services to individuals and corporate customers located in the St. Louis, Kansas City and Phoenix metropolitan markets through its banking subsidiary, Enterprise Bank & Trust (the “Bank”). The consolidated financial statements include the accounts of the Company, and its subsidiaries, all of which are wholly owned. All intercompany accounts and transactions have been eliminated.

The Company is subject to competition from other financial and nonfinancial institutions providing financial services in the markets served by the Company's subsidiary. Additionally, the Company and its banking subsidiary are subject to the regulations of certain federal and state agencies and undergo periodic examinations by those regulatory agencies.

Use of Estimates

The consolidated financial statements of the Company have been prepared in conformity in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”.) In preparing the consolidated financial statements, management is required to make estimates and assumptions, which significantly affect the reported amounts in the consolidated financial statements. Such estimates include the valuation of loans, goodwill, intangible assets, indemnification assets, and other long-lived assets, along with assumptions used in the calculation of income taxes, among others. These estimates and assumptions are based on management's best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. Management adjusts such estimates and assumptions when facts and circumstances dictate. Decreased real estate values, volatile credit markets, and persistent high unemployment have combined to increase the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.

Cash Flow Information

For purposes of reporting cash flows, the Company considers cash and due from banks, interest-bearing deposits and federal funds sold that mature within 90 days to be cash and cash equivalents.

Investments

The Company has classified all investments in debt securities as available for sale.

Securities classified as available for sale are carried at fair value. Unrealized holding gains and losses for available for sale securities are excluded from earnings and reported as a net amount in a separate component of shareholders' equity until realized. All previous fair value adjustments included in the separate component of shareholders' equity are reversed upon sale.

Declines in the fair value of securities below their cost that are deemed to be other-than-temporary are reflected in operations as realized losses. In estimating other-than-temporary impairment losses, management systematically evaluates investment securities for other-than-temporary declines in fair value on a quarterly basis.  This analysis requires management to consider various factors, which include (1) the present value of the cash flows expected to be collected compared to the amortized cost of the security, (2) duration and magnitude of the decline in value, (3) the financial condition of the issuer or issuers, (4) structure of the security, and (5) the intent to sell the security or whether it's more likely than not that the Company would be required to sell the security before its anticipated recovery in market value.

Premiums and discounts are amortized or accreted over the expected lives of the respective securities as an adjustment to yield using the interest method. Dividend and interest income is recognized when earned. Realized gains and losses are included in earnings and are derived using the specific identification method for determining the cost of securities sold.

Loans Receivable

The Company provides long-term financing of one-to-four-family residential real estate by originating fixed and variable rate loans. Long-term fixed and variable rate loans are sold into the secondary market with limited recourse. Upon receipt of an application for a real estate loan, the Company determines whether the loan will be sold into the secondary market or retained in the Company's loan portfolio. The interest rates on the loans sold are locked with the buyer and the Company bears no interest rate risk related to these loans. Mortgage loans held for sale are carried at the lower of cost or fair value, which is determined on a specific identification method. The Company does not retain servicing on any loans sold, nor did the Company have any capitalized mortgage servicing rights at December 31, 2013 or 2012. Gains on the sale of loans held for sale are reported net of direct origination fees and costs in the Company's consolidated statements of operations.

Portfolio Loans

Loans are reported at the principal balance outstanding net of unearned fees and costs. Loan origination fees and direct origination costs are deferred and recognized over the lives of the related loans as a yield adjustment using the interest method.

Interest income on loans is accrued to income based on the principal amount outstanding. The recognition of interest income is discontinued when a loan becomes 90 days past due or a significant deterioration in the borrower's credit has occurred which, in management's judgment, negatively impacts the collectability of the loan. Unpaid interest on such loans is reversed at the time the loan becomes uncollectable and subsequent interest payments received are applied to principal if any doubt exists as to the collectability of such principal; otherwise, such receipts are recorded as interest income. Loans that have not been restructured are returned to accrual status when management believes full collectability of principal and interest is expected. Non-accrual loans that have been restructured will remain in a non-accrual status until the borrower has made six consecutive contractual payments.

Loans Acquired Through Transfer

Loans acquired through the completion of a transfer, including loans acquired in a business combination that have evidence of deterioration of credit quality since origination and for which it is probable, at acquisition, that the Company will be unable to collect all contractually required payments receivable, are initially recorded at fair value (as determined by the present value of expected future cash flows) with no valuation allowance. The difference between the undiscounted cash flows expected at acquisition and the investment in the loans, or the “accretable yield,” is recognized as interest income on a level-yield method over the life of the loans. Contractually required payments for interest and principal that exceed the undiscounted cash flows expected at acquisition, or the “nonaccretable difference,” are not recognized as a yield adjustment or as a loss accrual or a valuation allowance. The Company aggregates individual loans with common risk characteristics into pools of loans. Increases in expected cash flows subsequent to the initial investment are recognized prospectively through adjustment of the yield on the loans over their remaining lives. Decreases in expected cash flows due to an inability to collect contractual cash flows are recognized as impairment through the provision for loan losses account. Any allowance for loan loss on these pools reflect only losses incurred after the acquisition (meaning the present value of all cash flows expected at acquisition that ultimately are not to be received). Any disposals of loans, including sales of loans, payments in full or foreclosures result in the removal of the loan from the loan pool at the carrying amount with differences in actual results reflected in interest income.

Allowance for Loan Losses

Loans are charged-off when the primary and secondary sources of repayment (cash flow, collateral, guarantors, etc) are less than their carrying value.

Allowance For Loan Losses

The allowance for loan losses is increased by provision charged to expense and is available to absorb charge-offs, net of recoveries. Management utilizes a systematic, documented approach in determining the appropriate level of the allowance for loan losses. The level of the allowance reflects management's continuing evaluation of industry concentrations; specific credit risks; loan loss experience; current loan portfolio quality; present economic, political and regulatory conditions; and probable losses inherent in the current loan portfolio. The determination of the appropriate level of the allowance for loan losses inherently involves a degree of subjectivity and requires that the Company make significant estimates of current credit risks and future trends, all of which may undergo material changes. Changes in economic conditions affecting borrowers, new information regarding existing loans, identification of additional problem loans and other factors, both within and outside of our control, may require an increase in the allowance for loan losses.

Management believes the allowance for loan losses is adequate to absorb inherent losses in the loan portfolio. While management uses available information to recognize losses on loans, future additions to the allowance may be necessary based on changes in economic conditions and other factors. In addition, various regulatory agencies, as an integral part of the examination process, periodically review the Bank's loan portfolio. Such agencies may require additions to the allowance for loan losses based on their judgments and interpretations of information available to them at the time of their examinations.

Allowance for Loan Losses on Purchase Credit Impaired Loans

The Company updates its cash flow projections for purchase credit impaired loans, including loans acquired with FDIC loss share coverage, on a quarterly basis. Assumptions utilized in this process include projections related to probability of default, loss severity, prepayment, extensions and recovery lag. Projections related to probability of default and prepayment are calculated utilizing a loan migration analysis. The loan migration analysis is a matrix of probability that specifies the probability of a loan pool transitioning into a particular delinquency or liquidation state given its current state at the re-measurement date. Loss severity factors are based upon industry data.

Any decreases in expected cash flows after the acquisition date and subsequent measurement periods are recognized by recording an impairment in the provision for loan losses. As a result of impairment, the FDIC loss share receivable is increased to reflect future cash to be received from the FDIC. The amount of the increase is recorded in noninterest income and is determined based on the specific loss share agreement, but is generally 80% of the losses. See Loans Acquired Through Transfer above for further discussion. Any increase in expected future cash flows due to a decrease in expected credit losses will reverse previously recorded impairment, if any, and add to the accretable yield on the loan pool, prospectively. In addition the accretion of the FDIC loss share receivable will decrease prospectively over the remaining life. Increases and decreases to the FDIC loss share receivable are recorded as adjustments to noninterest income.

Other Real Estate

Other real estate represents property acquired through foreclosure or deeded to the Company in lieu of foreclosure on loans on which the borrowers have defaulted on the payment of principal or interest. Other real estate is recorded on an individual asset basis at the lower of cost or fair value less estimated costs to sell. The fair value of other real estate is based upon estimates of future cash flows, market value of similar assets, if available, or independent appraisals. These estimates involve significant uncertainties and judgments. As a result, fair value estimates may not be realizable in a current sale or settlement of the other real estate. Subsequent reductions in fair value are expensed within noninterest expense.

Gains and losses resulting from the sale of other real estate are credited or charged to current period earnings. Costs of maintaining and operating other real estate are expensed as incurred, and expenditures to complete or improve other real estate properties are capitalized if the expenditures are expected to be recovered upon ultimate sale of the property.

FDIC Loss Share Receivable and Clawback Liability

As part of the FDIC- assisted transactions, the Bank entered into loss sharing agreements with the FDIC. The FDIC will reimburse the Bank for a percentage of realized losses on loans and foreclosed real estate covered under the agreement (“Covered Assets”). In addition, the Bank will be reimbursed for certain expenses related to the Covered Assets. At the acquisition date, the fair value of the amount due from the FDIC (“FDIC Loss Share Receivable") was estimated based on expected losses and cash flows on the Covered Assets. The FDIC Loss Share Receivable is measured separately from the related Covered Assets and recorded separately on the balance sheet because it is not contractually embedded in the Covered Assets and is not transferable.  Although these assets are contractual receivables from the FDIC, there are no contractual interest rates. See Note 2 - Acquisitions and Divestitures, for further information regarding these transactions.

Subsequent to initial recognition, the FDIC Loss Share Receivable is reviewed quarterly and adjusted for any changes in expected cash flows. These adjustments are measured on the same basis as the related Covered Assets. Any decrease in expected cash flows due to an increase in expected credit losses will increase the FDIC Loss Share Receivable which will partially offset the impairment recorded on the PCI loans. Any increase in expected future cash flows due to a decrease in expected credit losses will decrease the accretion of the FDIC Loss Share Receivable prospectively over its remaining life. Increases and decreases to the FDIC Loss Share Receivable are recorded as adjustments to noninterest income.

As stipulated in some of its agreements with the FDIC, the Company may be required to reimburse the FDIC if certain levels of cash flows are met over the duration of a loss share agreement. This reimbursement, or clawback liability, is measured quarterly over the duration of the agreement.

Fixed Assets

Buildings, leasehold improvements,furniture, fixtures, equipment, and capitalized software are stated at cost less accumulated depreciation. All categories are computed using the straight-line method over their respective estimated useful lives. Furniture, fixtures and equipment is depreciated over three to ten years, buildings and leasehold improvements over ten to forty years, and capitalized software over three years based upon estimated lives or lease obligation periods.

Tax Credits Held For Sale

The Company has purchased the rights to receive 10-year streams of state tax credits at agreed upon discount rates and sells such tax credits to wealth management customers and others. All state tax credits purchased prior to 2009 are accounted for at fair value. All state tax credits purchased since 2009 are accounted for at cost. The Company elected not to account for the state tax credits purchased since 2009 at fair value in order to limit the volatility of the fair value changes in the Company's consolidated statements of operations.

Cash Surrender Value of Life Insurance

The Company has purchased bank-owned life insurance policies on certain bank officers.  Bank-owned life insurance is recorded at its cash surrender value.  Changes in the cash surrender values are included in noninterest income.

Federal Home Loan Bank Stock

The Bank, as a member of the Federal Home Loan Bank of Des Moines (“FHLB”), is required to maintain an investment in the capital stock of the FHLB. The stock is redeemable at par by the FHLB, and is therefore, carried at cost and periodically evaluated for impairment.  The Company records FHLB dividends in interest income on the ex-dividend date.

Goodwill and Other Intangible Assets

The Company tests goodwill for impairment on an annual basis and whenever events or changes in circumstances indicate that the Company may not be able to recover the respective asset's carrying amount. The Company's annual test for impairment was performed in the fourth quarter of 2013. Such tests involve the use of estimates and assumptions. Core deposit intangibles are amortized using an accelerated method over an estimated useful life of approximately 10 years.

The Company identifies potential goodwill impairments by first performing a qualitative assessment and then by comparing the fair value of a reporting unit to its carrying amount, including goodwill. Goodwill impairment is not indicated as long as it is more likely than not that impairment has not occurred based on the qualitative assessment or based on the quantitative assessment the fair value of the reporting unit is greater than its carrying value. The second step of the impairment test is only required if a goodwill impairment is identified in step one. The second step of the test compares the implied fair value of goodwill to its carrying amount. If the carrying amount of goodwill exceeds its implied fair value, an impairment loss is recognized. That loss is equal to the carrying amount of goodwill that is in excess of its implied fair market value.

Impairment of Long-Lived Assets

Long-lived assets, such as fixed assets and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are separately presented in the balance sheet and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposal group classified as held for sale are presented separately in the appropriate asset and liability sections of the balance sheet.

Derivatives

The Company uses derivative financial instruments to assist in the management of interest rate sensitivity and to modify the repricing, maturity and option characteristics of certain assets and liabilities. In addition, the Company also offers an interest rate hedge program that includes interest rate swaps to assist its customers in managing their interest rate risk profile. In order to eliminate the interest rate risk associated with offering these products, the Company enters into derivative contracts with third parties to offset the customer contracts. 

Derivative instruments are required to be measured at fair value and recognized as either assets or liabilities in the consolidated financial statements. Fair value represents the payment the Company would receive or pay if the item were sold or bought in a current transaction. The accounting for changes in fair value (gains or losses) of a hedged item is dependent on whether the related derivative is designated and qualifies for “hedge accounting.” The Company assigns derivatives to one of these categories at the purchase date: cash flow hedge, fair value hedge, or non-designated derivatives. An assessment of the expected and ongoing hedge effectiveness of any derivative designated a fair value hedge or cash flow hedge is performed as required by the accounting standards. Derivatives are included in other assets and other liabilities in the consolidated balance sheets. Generally, the only derivative instruments used by the Company have been interest rate swaps and interest rate caps.

The following is a summary of the Company's accounting policies for derivative instruments and hedging activities.

• Cash Flow Hedges - Derivatives designated as cash flow hedges are recorded at fair value. The effective portion of the change in fair value is recorded (net of taxes) as a component of other comprehensive income (“OCI”) in shareholders' equity. Amounts recorded in OCI are subsequently reclassified into interest income or expense (depending on whether the hedged item is an asset or liability) when the underlying transaction affects earnings. The ineffective portion of the change in fair value is recorded in noninterest income. Upon dedesignation of a derivative financial instrument from a cash flow hedge relationship, any remaining amounts in OCI are recorded in noninterest income over the expected remaining life of the underlying forecasted hedge transaction. The net interest differential between the hedged item and the hedging derivative financial instrument are recorded as an adjustment to interest income or interest expense of the related asset or liability.

• Fair Value Hedges - For derivatives designated as fair value hedges, the change in fair value of the derivative instrument and related hedged item are recorded in the related interest income or expense, as applicable, except for the ineffective portion, which is recorded in noninterest income in the consolidated statements of income. The swap agreement is accounted for on an accrual basis with the net interest differential being recognized as an adjustment to interest income or interest expense of the related asset or liability.

• Non-Designated Derivatives - Certain derivative financial instruments are not designated as cash flow or as fair value hedges for accounting purposes. These non-designated derivatives are intended to provide interest rate protection on net interest income or noninterest income but do not meet hedge accounting treatment. Customer accommodation interest rate swap contracts are not designated as hedging instruments. Changes in the fair value of these instruments are recorded in interest income or noninterest income in the consolidated statements of income depending on the underlying hedged item.

Income Taxes

The Company and its subsidiaries file a consolidated federal income tax return. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. We evaluated the need for deferred tax asset valuation allowances based on a more-likely-than-not standard. The ability to realize deferred tax assets depends on the ability to generate sufficient positive taxable income within the carryback or carryforward periods provided for in the laws for each applicable taxing jurisdiction. We consider the following possible sources of taxable income: future reversal patterns of existing taxable temporary differences, future taxable income exclusive of reversing temporary differences, taxable income in prior carryback years and the availability of qualified tax planning strategies. The assessment regarding whether a valuation allowance is required or should be adjusted depends on all available positive and negative factors including, but not limited to, nature, frequency, and severity of recent losses, duration of available carryforward periods, historical experience with tax attributes expiring unused and near and medium term financial outlook. Because of the complexity of tax laws and regulations, interpretation can be difficult and subject to legal judgment given specific facts and circumstances. It is possible that others, given the same information, may at any point in time reach different reasonable conclusions regarding the estimated amounts of accrued taxes.

Stock-Based Compensation

Stock-based compensation is recognized as an expense in the consolidated financial statements and measured at the grant date fair value for all equity classified awards and recognized over the required service period.

Acquisitions and Divestitures

The Company accounts for business combinations using the acquisition method of accounting. Accordingly, the assets and liabilities of the acquired entities have been recorded at their estimated fair values at the date of acquisition. Goodwill represents the excess of the purchase price over the fair value of net assets, including the amount assigned to identifiable intangible assets.

The purchase price allocation process requires an estimation of the fair values of the assets acquired and the liabilities assumed. When a business combination agreement provides for an adjustment to the cost of the combination contingent on future events, the Company includes an estimate of the acquisition-date fair value as part of the cost of the combination. The results of operations of the acquired business are included in the Company's consolidated financial statements from the respective date of acquisition. As a general rule, goodwill established in connection with a stock purchase is non-deductible for tax purposes.

For divestitures, the Company measures an asset (disposal group) classified as held for sale at the lower of its carrying value at the date the asset is initially classified as held for sale or its fair value less costs to sell. The Company reports the results of operations of a component that either has been disposed of or held for sale as discontinued operations if:

• The operations and cash flows of the disposal group will be eliminated from the ongoing operations as a result of the disposal transaction, and

• The Company will not have any significant continuing involvement in the operations of the entity after the disposal transaction.

Any incremental direct costs incurred to transact the sale are allocated against the gain or loss on the sale. These costs would include items like legal fees, title transfer fees, broker fees, etc. Any goodwill and intangible assets associated with the portion of the reporting unit to be disposed of is included in the carrying amount of the business in determining the gain or loss on the sale.

Basic and Diluted Earnings Per Common Share

Reclassification

Marketable securities

The unrealized losses at both December 31, 2013, and December 31, 2012, were primarily attributable to changes in market interest rates since the securities were purchased. Management systematically evaluates investment securities for other-than-temporary declines in fair value on a quarterly basis. This analysis requires management to consider various factors, which include among other considerations (1) the present value of the cash flows expected to be collected compared to the amortized cost of the security, (2) duration and magnitude of the decline in value, (3) the financial condition of the issuer or issuers, (4) structure of the security, and (5) the intent to sell the security or whether it is more likely than not that the Company would be required to sell the security before its anticipated recovery in market value. At December 31, 2013, management performed its quarterly analysis of all securities with an unrealized loss and concluded no individual securities were other-than-temporarily impaired.

Subordinated Debentures

SUBORDINATED DEBENTURES

The Company has nine unconsolidated statutory business trusts. These trusts issued preferred securities that were sold to third parties. The sole purpose of the trusts was to invest the proceeds in junior subordinated debentures of the Company that have terms identical to the trust preferred securities.

The amounts and terms of each respective issuance at December 31, 2013 and 2012 were as follows:

	Amount				Maturity Date	Call Date	Interest Rate
(in thousands)	2013		2012
EFSC Clayco Statutory Trust I	$	3,196	$	3,196	December 17, 2033	December 17, 2008	Floats @ 3MO LIBOR + 2.85%

Total trust preferred securities	$	62,581	$	82,581
Bank subordinated notes	—		2,500		October 1, 2018	October 1, 2013	Fixed @ 10%
Total subordinated debentures	$	62,581	$	85,081

The subordinated debentures, which are the sole assets of the trusts, are subordinate and junior in right of payment to all present and future senior and subordinated indebtedness and certain other financial conditions of the Company. The Company fully and unconditionally guarantees each trust's securities obligations. Under current regulations, the trust preferred securities are included in Tier 1 capital for regulatory capital purposes, subject to certain limitations.

The securities are redeemable in whole or in part on or after their respective call dates. Mandatory redemption dates may be shortened if certain conditions are met. The securities are classified as subordinated debentures in the Company's consolidated balance sheets. Interest on the subordinated debentures held by the trusts is recorded as interest expense in the Company's consolidated statements of operations. The Company's investment of $2.6 million at December 31, 2013, in these trusts is included in other investments in the consolidated balance sheets.

On August 15, 2013, the Company converted $20.0 million of its trust preferred in EFSC Capital Trust VIII into 1.2 million shares of common stock. The Company issued 25,060 shares of additional common stock as an inducement for the conversion. The inducement resulted in a $0.4 million expense recorded in Other noninterest expense during 2013. The remaining trust preferred securities issued through EFSC Capital Trust VIII are callable by the Company and convertible into shares of the Company's common stock at a conversion price of $17.37. An entity managed and controlled by a former member of the Company's Board of Directors purchased $5.0 million of the convertible trust preferred securities of EFSC Capital Trust VIII on December 12, 2008. Certain current directors still have a nominal interest in this entity.

On June 25, 2013, the Company repaid $2.0 million of its 10% subordinated notes. The remaining $0.5 million was repaid on October 1, 2013.

Compensation Plans

COMPENSATION PLANS

The Company has adopted share-based compensation plans to reward and provide long-term incentive for directors and key employees of the Company. These plans provide for the granting of stock, stock options, stock-settled stock appreciation rights ("SSARs"), and restricted stock units (“RSUs”), as designated by the Company's Board of Directors upon the recommendation of the Compensation Committee. The Company uses authorized and unissued shares to satisfy share award exercises. There were no options or SSARs granted in 2013. At December 31, 2013, there were 978,660 shares available for grant under the various share-based compensation plans.

Total share-based compensation expense that was charged against income was $5.0 million, $2.5 million, and $1.8 million for the years ended December 31, 2013, 2012, and 2011 respectively. The total income tax benefit/(expense) recognized in additional paid in capital for share-based compensation arrangements was $0.2 million, $0.1 million, and $(0.1) million for the years ended December 31, 2013, 2012, and 2011, respectively.

Employee Stock Options and Stock-settled Stock Appreciation Rights

In determining compensation cost for stock options and SSARs, the Black-Scholes option-pricing model is used to estimate the fair value on date of grant. The Black-Scholes model is a closed-end model that uses the assumptions in the following table. There were no grants of employee stock options or SSARs during the years ended December 31, 2013, 2012, or 2011.

Stock options have been granted to key employees with exercise prices equal to the market price of the Company's common stock at the date of grant and 10-year contractual terms. Stock options have a vesting schedule of three to five years. The SSARs are subject to continued employment, have a 10-year contractual term and vest ratably over five years. Neither stock options nor SSARs carry voting or dividend rights until exercised. At December 31, 2013, there was $152,671 of total unrecognized compensation cost related to SSARs which is expected to be recognized over a weighted average period of 1.59 years. Various information related to the stock options and SSARs is shown below.

(in thousands)	2013		2012		2011
Compensation expense	$	213	$	478	$	911
Intrinsic value of option exercises on date of exercise	$	300	$	327	$	132

Restricted Stock Units (“RSU”)

As part of a long-term incentive plan, the Company awards nonvested stock, in the form of RSUs to employees. RSUs are subject to continued employment and vest ratably over three to five years. RSUs do not carry voting or dividend rights until vested. Sales of the units are restricted prior to vesting. Various information related to the RSUs is shown below.

Stock Plan for Non-Management Directors

In 2006, the Company adopted a Stock Plan for Non-Management Directors, which provides for issuing 100,000 shares of common stock to non-employee directors as compensation in lieu of cash. In 2012, an amendment to the plan was approved by the shareholders allowing a total of up to 200,000 shares to be awarded. At December 31, 2013, there were 83,764 shares of stock available for issuance under the Stock Plan for Non-Management Directors. Shares are issued twice a year and compensation expense is recorded as the shares are earned, therefore, there is no unrecognized compensation cost related to this plan. In 2013, the Company issued 16,990 shares of stock at a weighted average fair value of $15.40 per share. In 2012, the Company issued 18,410 shares of stock at a weighted average fair value of $14.00 per share. In 2011, the Company issued 19,830 shares of stock at a weighted average fair value of $12.90 per share. The Company recognized $0.3 million of stock-based compensation expense for the shares issued to the directors in 2013, 2012, and 2011, respectively.

Employee Stock Issuance

Restricted stock was issued to certain key employees as part of their compensation. The restricted stock may be in the form of a one-time award or paid in pro rata installments. The stock is restricted for at least 2 years and upon issuance may be fully vested or vest over 5 years. The Company recognized $0.6 million, $0.2 million, and $30,000 of stock-based compensation expense for the shares issued to the employees in 2013, 2012, and 2011, respectively. The Company issued 37,943, 71,899, and 6,724 shares in 2013, 2012, and 2011, respectively.

In 2011, 2012 and 2013, the Company entered into long-term incentive agreements with certain key employees. These open awards are conditioned on certain performance criteria and market criteria measured against a group of peer banks over a 3 year period for each grant. The amount of the awards are determined at the end of the 3 year vesting period. In February 2014, the Company issued 146,700 shares to employees upon completion of the 2011-2013 performance cycle. The 2012 and 2013 grants are not yet determinable. The Company recorded $3.2 million, $1.3 million and $0 of stock-based compensation expense for these awards during 2013, 2012 and 2011, respectively.

401(k) plans

The Company has a 401(k) savings plan which covers substantially all full-time employees over the age of 21. The amount charged to expense for the Company's contributions to the plan was $1.2 million, $1.2 million and $1.1 million for 2013, 2012, and 2011, respectively.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The significant accounting policies used by the Company in the preparation of the consolidated financial statements are summarized below:

Business and Consolidation

Enterprise Financial Services Corp and subsidiaries (the “Company” or “Enterprise”) is a financial holding company that provides a full range of banking and wealth management services to individuals and corporate customers located in the St. Louis, Kansas City and Phoenix metropolitan markets through its banking subsidiary, Enterprise Bank & Trust (the “Bank”). The consolidated financial statements include the accounts of the Company, and its subsidiaries, all of which are wholly owned. All intercompany accounts and transactions have been eliminated.

The Company is subject to competition from other financial and nonfinancial institutions providing financial services in the markets served by the Company's subsidiary. Additionally, the Company and its banking subsidiary are subject to the regulations of certain federal and state agencies and undergo periodic examinations by those regulatory agencies.

Adoption of New Accounting Guidance

The Company has adopted the accounting guidance within ASU 2014-1 "Investments-Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects." As required by the ASU, the Company revised its prior period financial statements to move the losses associated with its investments from Other noninterest expense to income tax expense. The impact of the revision to adopt the ASU was a decrease in Other Non-interest Expense and a similar increase in Income Tax Expense of $0.9 million for the years ended December 31, 2013, 2012 and 2011, respectively.

Use of Estimates

The consolidated financial statements of the Company have been prepared in conformity in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”.) In preparing the consolidated financial statements, management is required to make estimates and assumptions, which significantly affect the reported amounts in the consolidated financial statements. Such estimates include the valuation of loans, goodwill, intangible assets, indemnification assets, and other long-lived assets, along with assumptions used in the calculation of income taxes, among others. These estimates and assumptions are based on management's best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. Management adjusts such estimates and assumptions when facts and circumstances dictate. Decreased real estate values, volatile credit markets, and persistent high unemployment have combined to increase the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.

Cash Flow Information

For purposes of reporting cash flows, the Company considers cash and due from banks, interest-bearing deposits and federal funds sold that mature within 90 days to be cash and cash equivalents. At December 31, 2013 and 2012, approximately $16.8 million and $16.5 million, respectively, of cash and due from banks represented required reserves on deposits maintained by the Company in accordance with Federal Reserve Bank requirements.

Investments

The Company has classified all investments in debt securities as available for sale.

Securities classified as available for sale are carried at fair value. Unrealized holding gains and losses for available for sale securities are excluded from earnings and reported as a net amount in a separate component of shareholders' equity until realized. All previous fair value adjustments included in the separate component of shareholders' equity are reversed upon sale.

Declines in the fair value of securities below their cost that are deemed to be other-than-temporary are reflected in operations as realized losses. In estimating other-than-temporary impairment losses, management systematically evaluates investment securities for other-than-temporary declines in fair value on a quarterly basis.  This analysis requires management to consider various factors, which include (1) the present value of the cash flows expected to be collected compared to the amortized cost of the security, (2) duration and magnitude of the decline in value, (3) the financial condition of the issuer or issuers, (4) structure of the security, and (5) the intent to sell the security or whether it's more likely than not that the Company would be required to sell the security before its anticipated recovery in market value.

Premiums and discounts are amortized or accreted over the expected lives of the respective securities as an adjustment to yield using the interest method. Dividend and interest income is recognized when earned. Realized gains and losses are included in earnings and are derived using the specific identification method for determining the cost of securities sold.

Loans Held for Sale

The Company provides long-term financing of one-to-four-family residential real estate by originating fixed and variable rate loans. Long-term fixed and variable rate loans are sold into the secondary market with limited recourse. Upon receipt of an application for a real estate loan, the Company determines whether the loan will be sold into the secondary market or retained in the Company's loan portfolio. The interest rates on the loans sold are locked with the buyer and the Company bears no interest rate risk related to these loans. Mortgage loans held for sale are carried at the lower of cost or fair value, which is determined on a specific identification method. The Company does not retain servicing on any loans sold, nor did the Company have any capitalized mortgage servicing rights at December 31, 2013 or 2012. Gains on the sale of loans held for sale are reported net of direct origination fees and costs in the Company's consolidated statements of operations.

Portfolio Loans

Loans are reported at the principal balance outstanding net of unearned fees and costs. Loan origination fees and direct origination costs are deferred and recognized over the lives of the related loans as a yield adjustment using the interest method.

Interest income on loans is accrued to income based on the principal amount outstanding. The recognition of interest income is discontinued when a loan becomes 90 days past due or a significant deterioration in the borrower's credit has occurred which, in management's judgment, negatively impacts the collectability of the loan. Unpaid interest on such loans is reversed at the time the loan becomes uncollectable and subsequent interest payments received are applied to principal if any doubt exists as to the collectability of such principal; otherwise, such receipts are recorded as interest income. Loans that have not been restructured are returned to accrual status when management believes full collectability of principal and interest is expected. Non-accrual loans that have been restructured will remain in a non-accrual status until the borrower has made six consecutive contractual payments.

Loans Acquired Through Transfer

Loans acquired through the completion of a transfer, including loans acquired in a business combination that have evidence of deterioration of credit quality since origination and for which it is probable, at acquisition, that the Company will be unable to collect all contractually required payments receivable, are initially recorded at fair value (as determined by the present value of expected future cash flows) with no valuation allowance. The difference between the undiscounted cash flows expected at acquisition and the investment in the loans, or the “accretable yield,” is recognized as interest income on a level-yield method over the life of the loans. Contractually required payments for interest and principal that exceed the undiscounted cash flows expected at acquisition, or the “nonaccretable difference,” are not recognized as a yield adjustment or as a loss accrual or a valuation allowance. The Company aggregates individual loans with common risk characteristics into pools of loans. Increases in expected cash flows subsequent to the initial investment are recognized prospectively through adjustment of the yield on the loans over their remaining lives. Decreases in expected cash flows due to an inability to collect contractual cash flows are recognized as impairment through the provision for loan losses account. Any allowance for loan loss on these pools reflect only losses incurred after the acquisition (meaning the present value of all cash flows expected at acquisition that ultimately are not to be received). Any disposals of loans, including sales of loans, payments in full or foreclosures result in the removal of the loan from the loan pool at the carrying amount with differences in actual results reflected in interest income.

Impaired Loans

Loans are considered “impaired” when it becomes probable that the Company will be unable to collect all amounts due according to the loan's contractual terms. Non-accrual loans, loans past due greater than 90 days and still accruing, unless adequately secured and in the process of collection, and restructured loans qualify as “impaired loans.” Restructured loans involve the granting of a concession to a borrower experiencing financial difficulty involving the modification of terms of the loan, such as changes in payment schedule or interest rate.

When measuring impairment, the expected future cash flows of an impaired loan are discounted at the loan's effective interest rate at origination. Alternatively, impairment can be measured by reference to an observable market price, if one exists, or the fair value of the collateral for a collateral-dependent loan. Interest income on impaired loans is not accrued but is recorded when cash is received and only if principal is considered to be fully collectable. Loans and leases, which are deemed uncollectable, are charged off to the allowance for loan losses, while recoveries of amounts previously charged off are credited to the allowance for loan losses.

Impaired loans exclude credit-impaired loans that were acquired in the FDIC-assisted transactions. These purchased credit-impaired loans are accounted for on a pool basis and are generally considered accruing and performing loans as the loans accrete interest income over the estimated life of the loan when cash flows are reasonably estimable. Accordingly, acquired credit impaired loans that are contractually past due may still be considered to be accruing and performing loans. If the timing and amount of future cash flows is not reasonably estimable, the loans may be classified as nonaccrual loans and the purchase price discount on those loans is not recorded as interest income until the timing and amount of future cash flows can be reasonably estimated. See Note 2 - Acquisitions and Divestitures and Note 7 - Purchase Credit Impaired ("PCI") Loans for more information on these loans.

Loan Charge-Offs

Loans are charged-off when the primary and secondary sources of repayment (cash flow, collateral, guarantors, etc) are less than their carrying value.

Allowance For Loan Losses

The allowance for loan losses is increased by provision charged to expense and is available to absorb charge-offs, net of recoveries. Management utilizes a systematic, documented approach in determining the appropriate level of the allowance for loan losses. The level of the allowance reflects management's continuing evaluation of industry concentrations; specific credit risks; loan loss experience; current loan portfolio quality; present economic, political and regulatory conditions; and probable losses inherent in the current loan portfolio. The determination of the appropriate level of the allowance for loan losses inherently involves a degree of subjectivity and requires that the Company make significant estimates of current credit risks and future trends, all of which may undergo material changes. Changes in economic conditions affecting borrowers, new information regarding existing loans, identification of additional problem loans and other factors, both within and outside of our control, may require an increase in the allowance for loan losses.

Management believes the allowance for loan losses is adequate to absorb inherent losses in the loan portfolio. While management uses available information to recognize losses on loans, future additions to the allowance may be necessary based on changes in economic conditions and other factors. In addition, various regulatory agencies, as an integral part of the examination process, periodically review the Bank's loan portfolio. Such agencies may require additions to the allowance for loan losses based on their judgments and interpretations of information available to them at the time of their examinations.

Allowance for Loan Losses on Purchase Credit Impaired Loans

The Company updates its cash flow projections for purchase credit impaired loans, including loans acquired with FDIC loss share coverage, on a quarterly basis. Assumptions utilized in this process include projections related to probability of default, loss severity, prepayment, extensions and recovery lag. Projections related to probability of default and prepayment are calculated utilizing a loan migration analysis. The loan migration analysis is a matrix of probability that specifies the probability of a loan pool transitioning into a particular delinquency or liquidation state given its current state at the re-measurement date. Loss severity factors are based upon industry data.

Any decreases in expected cash flows after the acquisition date and subsequent measurement periods are recognized by recording an impairment in the provision for loan losses. As a result of impairment, the FDIC loss share receivable is increased to reflect future cash to be received from the FDIC. The amount of the increase is recorded in noninterest income and is determined based on the specific loss share agreement, but is generally 80% of the losses. See Loans Acquired Through Transfer above for further discussion. Any increase in expected future cash flows due to a decrease in expected credit losses will reverse previously recorded impairment, if any, and add to the accretable yield on the loan pool, prospectively. In addition the accretion of the FDIC loss share receivable will decrease prospectively over the remaining life. Increases and decreases to the FDIC loss share receivable are recorded as adjustments to noninterest income.

Other Real Estate

Other real estate represents property acquired through foreclosure or deeded to the Company in lieu of foreclosure on loans on which the borrowers have defaulted on the payment of principal or interest. Other real estate is recorded on an individual asset basis at the lower of cost or fair value less estimated costs to sell. The fair value of other real estate is based upon estimates of future cash flows, market value of similar assets, if available, or independent appraisals. These estimates involve significant uncertainties and judgments. As a result, fair value estimates may not be realizable in a current sale or settlement of the other real estate. Subsequent reductions in fair value are expensed within noninterest expense.

Gains and losses resulting from the sale of other real estate are credited or charged to current period earnings. Costs of maintaining and operating other real estate are expensed as incurred, and expenditures to complete or improve other real estate properties are capitalized if the expenditures are expected to be recovered upon ultimate sale of the property.

FDIC Loss Share Receivable and Clawback Liability

As part of the FDIC- assisted transactions, the Bank entered into loss sharing agreements with the FDIC. The FDIC will reimburse the Bank for a percentage of realized losses on loans and foreclosed real estate covered under the agreement (“Covered Assets”). In addition, the Bank will be reimbursed for certain expenses related to the Covered Assets. At the acquisition date, the fair value of the amount due from the FDIC (“FDIC Loss Share Receivable") was estimated based on expected losses and cash flows on the Covered Assets. The FDIC Loss Share Receivable is measured separately from the related Covered Assets and recorded separately on the balance sheet because it is not contractually embedded in the Covered Assets and is not transferable.  Although these assets are contractual receivables from the FDIC, there are no contractual interest rates. See Note 2 - Acquisitions and Divestitures, for further information regarding these transactions.

Subsequent to initial recognition, the FDIC Loss Share Receivable is reviewed quarterly and adjusted for any changes in expected cash flows. These adjustments are measured on the same basis as the related Covered Assets. Any decrease in expected cash flows due to an increase in expected credit losses will increase the FDIC Loss Share Receivable which will partially offset the impairment recorded on the PCI loans. Any increase in expected future cash flows due to a decrease in expected credit losses will decrease the accretion of the FDIC Loss Share Receivable prospectively over its remaining life. Increases and decreases to the FDIC Loss Share Receivable are recorded as adjustments to noninterest income.

As stipulated in some of its agreements with the FDIC, the Company may be required to reimburse the FDIC if certain levels of cash flows are met over the duration of a loss share agreement. This reimbursement, or clawback liability, is measured quarterly over the duration of the agreement.

Fixed Assets

Buildings, leasehold improvements,furniture, fixtures, equipment, and capitalized software are stated at cost less accumulated depreciation. All categories are computed using the straight-line method over their respective estimated useful lives. Furniture, fixtures and equipment is depreciated over three to ten years, buildings and leasehold improvements over ten to forty years, and capitalized software over three years based upon estimated lives or lease obligation periods.

State Tax Credits Held for Sale

The Company has purchased the rights to receive 10-year streams of state tax credits at agreed upon discount rates and sells such tax credits to wealth management customers and others. All state tax credits purchased prior to 2009 are accounted for at fair value. All state tax credits purchased since 2009 are accounted for at cost. The Company elected not to account for the state tax credits purchased since 2009 at fair value in order to limit the volatility of the fair value changes in the Company's consolidated statements of operations.

Cash Surrender Value of Life Insurance

The Company has purchased bank-owned life insurance policies on certain bank officers.  Bank-owned life insurance is recorded at its cash surrender value.  Changes in the cash surrender values are included in noninterest income.

Federal Home Loan Bank Stock

The Bank, as a member of the Federal Home Loan Bank of Des Moines (“FHLB”), is required to maintain an investment in the capital stock of the FHLB. The stock is redeemable at par by the FHLB, and is therefore, carried at cost and periodically evaluated for impairment.  The Company records FHLB dividends in interest income on the ex-dividend date.

Goodwill and Other Intangible Assets

The Company tests goodwill for impairment on an annual basis and whenever events or changes in circumstances indicate that the Company may not be able to recover the respective asset's carrying amount. The Company's annual test for impairment was performed in the fourth quarter of 2013. Such tests involve the use of estimates and assumptions. Core deposit intangibles are amortized using an accelerated method over an estimated useful life of approximately 10 years.

The Company identifies potential goodwill impairments by first performing a qualitative assessment and then by comparing the fair value of a reporting unit to its carrying amount, including goodwill. Goodwill impairment is not indicated as long as it is more likely than not that impairment has not occurred based on the qualitative assessment or based on the quantitative assessment the fair value of the reporting unit is greater than its carrying value. The second step of the impairment test is only required if a goodwill impairment is identified in step one. The second step of the test compares the implied fair value of goodwill to its carrying amount. If the carrying amount of goodwill exceeds its implied fair value, an impairment loss is recognized. That loss is equal to the carrying amount of goodwill that is in excess of its implied fair market value.

Impairment of Long-Lived Assets

Long-lived assets, such as fixed assets and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are separately presented in the balance sheet and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposal group classified as held for sale are presented separately in the appropriate asset and liability sections of the balance sheet.

Derivative Financial Instruments and Hedging Activities

The Company uses derivative financial instruments to assist in the management of interest rate sensitivity and to modify the repricing, maturity and option characteristics of certain assets and liabilities. In addition, the Company also offers an interest rate hedge program that includes interest rate swaps to assist its customers in managing their interest rate risk profile. In order to eliminate the interest rate risk associated with offering these products, the Company enters into derivative contracts with third parties to offset the customer contracts. 

Derivative instruments are required to be measured at fair value and recognized as either assets or liabilities in the consolidated financial statements. Fair value represents the payment the Company would receive or pay if the item were sold or bought in a current transaction. The accounting for changes in fair value (gains or losses) of a hedged item is dependent on whether the related derivative is designated and qualifies for “hedge accounting.” The Company assigns derivatives to one of these categories at the purchase date: cash flow hedge, fair value hedge, or non-designated derivatives. An assessment of the expected and ongoing hedge effectiveness of any derivative designated a fair value hedge or cash flow hedge is performed as required by the accounting standards. Derivatives are included in other assets and other liabilities in the consolidated balance sheets. Generally, the only derivative instruments used by the Company have been interest rate swaps and interest rate caps.

The following is a summary of the Company's accounting policies for derivative instruments and hedging activities.

• Cash Flow Hedges - Derivatives designated as cash flow hedges are recorded at fair value. The effective portion of the change in fair value is recorded (net of taxes) as a component of other comprehensive income (“OCI”) in shareholders' equity. Amounts recorded in OCI are subsequently reclassified into interest income or expense (depending on whether the hedged item is an asset or liability) when the underlying transaction affects earnings. The ineffective portion of the change in fair value is recorded in noninterest income. Upon dedesignation of a derivative financial instrument from a cash flow hedge relationship, any remaining amounts in OCI are recorded in noninterest income over the expected remaining life of the underlying forecasted hedge transaction. The net interest differential between the hedged item and the hedging derivative financial instrument are recorded as an adjustment to interest income or interest expense of the related asset or liability.

• Fair Value Hedges - For derivatives designated as fair value hedges, the change in fair value of the derivative instrument and related hedged item are recorded in the related interest income or expense, as applicable, except for the ineffective portion, which is recorded in noninterest income in the consolidated statements of income. The swap agreement is accounted for on an accrual basis with the net interest differential being recognized as an adjustment to interest income or interest expense of the related asset or liability.

• Non-Designated Derivatives - Certain derivative financial instruments are not designated as cash flow or as fair value hedges for accounting purposes. These non-designated derivatives are intended to provide interest rate protection on net interest income or noninterest income but do not meet hedge accounting treatment. Customer accommodation interest rate swap contracts are not designated as hedging instruments. Changes in the fair value of these instruments are recorded in interest income or noninterest income in the consolidated statements of income depending on the underlying hedged item.

Income Taxes

The Company and its subsidiaries file a consolidated federal income tax return. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. We evaluated the need for deferred tax asset valuation allowances based on a more-likely-than-not standard. The ability to realize deferred tax assets depends on the ability to generate sufficient positive taxable income within the carryback or carryforward periods provided for in the laws for each applicable taxing jurisdiction. We consider the following possible sources of taxable income: future reversal patterns of existing taxable temporary differences, future taxable income exclusive of reversing temporary differences, taxable income in prior carryback years and the availability of qualified tax planning strategies. The assessment regarding whether a valuation allowance is required or should be adjusted depends on all available positive and negative factors including, but not limited to, nature, frequency, and severity of recent losses, duration of available carryforward periods, historical experience with tax attributes expiring unused and near and medium term financial outlook. Because of the complexity of tax laws and regulations, interpretation can be difficult and subject to legal judgment given specific facts and circumstances. It is possible that others, given the same information, may at any point in time reach different reasonable conclusions regarding the estimated amounts of accrued taxes.

Stock-Based Compensation

Stock-based compensation is recognized as an expense in the consolidated financial statements and measured at the grant date fair value for all equity classified awards and recognized over the required service period.

Acquisitions and Divestitures

The Company accounts for business combinations using the acquisition method of accounting. Accordingly, the assets and liabilities of the acquired entities have been recorded at their estimated fair values at the date of acquisition. Goodwill represents the excess of the purchase price over the fair value of net assets, including the amount assigned to identifiable intangible assets.

The purchase price allocation process requires an estimation of the fair values of the assets acquired and the liabilities assumed. When a business combination agreement provides for an adjustment to the cost of the combination contingent on future events, the Company includes an estimate of the acquisition-date fair value as part of the cost of the combination. The results of operations of the acquired business are included in the Company's consolidated financial statements from the respective date of acquisition. As a general rule, goodwill established in connection with a stock purchase is non-deductible for tax purposes.

For divestitures, the Company measures an asset (disposal group) classified as held for sale at the lower of its carrying value at the date the asset is initially classified as held for sale or its fair value less costs to sell. The Company reports the results of operations of a component that either has been disposed of or held for sale as discontinued operations if:

• The operations and cash flows of the disposal group will be eliminated from the ongoing operations as a result of the disposal transaction, and

• The Company will not have any significant continuing involvement in the operations of the entity after the disposal transaction.

Any incremental direct costs incurred to transact the sale are allocated against the gain or loss on the sale. These costs would include items like legal fees, title transfer fees, broker fees, etc. Any goodwill and intangible assets associated with the portion of the reporting unit to be disposed of is included in the carrying amount of the business in determining the gain or loss on the sale.

Basic and Diluted Earnings Per Common Share

Basic earnings per common share data is calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Common shares outstanding include common stock and restricted stock awards where recipients have satisfied the vesting terms. Diluted earnings per common share gives effect to all dilutive potential common shares outstanding during the period using the treasury stock method and the if-converted method for convertible securities related to the issuance of trust preferred securities.

Consolidated Statement of Comprehensive Income

The Consolidated Statement of Comprehensive Income includes the amount and the related tax impact that have been reclassified from accumulated other comprehensive income to net income. The classification adjustment for unrealized loss/gain on sale of securities included in net income has been recorded through the gain on sale of investment securities line item, within noninterest income, in the Company's Consolidated Statements of Operations.

Income Taxes

INCOME TAXES

The components of income tax (benefit) expense for the years ended December 31 are as follows:

	Years ended December 31,
(in thousands)	2013			2012			2011

Deferred	(9,943		)	(8,535		)	(733		)
Total income tax expense	$	16,976		$	14,534		$	12,802

A reconciliation of expected income tax expense, computed by applying the statutory federal income tax rate of 35% in 2013, 2012, and 2011 to income before income taxes and the amounts reflected in the consolidated statements of operations is as follows:

	Years ended December 31,
(in thousands)	2013			2012			2011
Income tax expense at statutory rate	$	17,528		$	14,991		$	13,379

Tax benefits of LIHTC investments, net	(204		)	(211		)	(174		)
Other, net	(608		)	(598		)	435
Total income tax expense	$	16,976		$	14,534		$	12,802

The amount of tax credits and other tax benefits from low-income housing tax credit ("LIHTC") investments recognized during the year were $1.1 million, $1.1 million, and $1.0 million during the years ended December 31, 2013, 2012, and 2011, respectively. The amount recognized as a component of income tax expense per the table above was $0.2 million, $0.2 million, and $0.2 million for the years ended December 31, 2013, 2012, and 2011, respectively. As of December 31, 2013 and 2012, the carrying value of the investments related to low-income housing tax credits was $4.2 million and $5.1 million, respectively. No impairment losses have been recognized from forfeiture or ineligibility of tax credits or other circumstances during the life of any of the investments. As of December 31, 2013, the Company has future capital commitments of $0.6 million related to low-income housing tax credit investments. The capital commitments are expected to be called between the years 2014 - 2024.

A net deferred income tax asset of $39.4 million and $21.8 million is included in other assets in the consolidated balance sheets at December 31, 2013 and 2012, respectively. The tax effect of temporary differences that gave rise to significant portions of the deferred tax assets and deferred tax liabilities is as follows:

	Years ended December 31,
(in thousands)	2013		2012
Deferred tax assets:
Allowance for loan losses	$	16,365	$	17,846
Asset purchase tax basis difference, net	16,238		18,399
Basis difference on other real estate	1,611		1,222
Deferred compensation	4,604		2,815
Goodwill and other intangible assets	10,799		12,657
Accrued compensation	2,046		1,700
Unrealized losses on securities available for sale	2,672		—
Other, net	796		115
Total deferred tax assets	$	55,131	$	54,754
Deferred tax liabilities:
FDIC loss guarantee receivable, net	$	12,280	$	23,259
Unrealized gains on securities available for sale	—		4,960
State tax credits held for sale, net of economic hedge	1,368		1,875
Core deposit intangibles	2,075		2,881
Total deferred tax liabilities	15,723		32,975
Net deferred tax asset	$	39,408	$	21,779

A valuation allowance is provided on deferred tax assets when it is more likely than not that some portion of the assets will not be realized. The Company did not have any valuation allowances for federal income taxes as of December 31, 2013 or 2012. Management believes it is more likely than not that the results of future operations will generate sufficient federal taxable income to realize the deferred federal tax assets. Due to positive evidence about the Company's ability to generate taxable income in the future, the Company reversed its state valuation allowance in 2012. Accordingly, the Company had no state tax valuation allowance as of December 31, 2013 and 2012.

The Company and its subsidiaries file income tax returns in the federal jurisdiction and in nine states. With few exceptions, the Company is no longer subject to federal, state or local income tax audits by tax authorities for years before 2010. The Company is not currently under audit by any taxing jurisdiction.

The Company recognizes interest and penalties related to uncertain tax positions in income tax expense and classifies such interest and penalties in the liability for unrecognized tax benefits. The amounts accrued for interest and penalties as of December 31, 2013, 2012, and 2011 were not significant.

As of December 31, 2013, the gross amount of unrecognized tax benefits was $1.3 million and the total amount of net unrecognized tax benefits that would impact the effective tax rate, if recognized, was $0.8 million. As of December 31, 2012 and 2011, the total amount of the net unrecognized tax benefits that would impact the effective tax rate, if recognized, was $0.8 million and $0.7 million, respectively. The Company believes it is reasonably possible that the gross amount of unrecognized benefits will be reduced by approximately $0.3 million as a result of a lapse of statute of limitations in the next 12 months.

The activity in the gross liability for unrecognized tax benefits was as follows:

(in thousands)	2013			2012			2011
Balance at beginning of year	$	1,148		$	1,057		$	4,003
Additions based on tax positions related to the current year	233			347			311
Additions for tax positions of prior years	53			49			38
Reductions for tax positions of prior years	—			—			(2,849		)
Settlements or lapse of statute of limitations	(177		)	(305		)	(446		)
Balance at end of year	$	1,257		$	1,148		$	1,057
