ITEM 1. BUSINESS

Background

The disclosures set forth in this item are qualified by Item 1A. Risk Factors and the section captioned “Forward-Looking Statements” in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations of this report and other cautionary statements set forth elsewhere in this report.

Texas Capital Bancshares, Inc. (“we”, “us” or the “Company”), a Delaware corporation organized in 1996, is the parent of Texas Capital Bank, National Association (the “Bank”). The Company is a registered bank holding company and a financial holding company.

The Bank is headquartered in Dallas, with primary banking offices in Austin, Dallas, Fort Worth, Houston, and San Antonio, the five largest metropolitan areas of Texas. All of our business activities are conducted through the Bank. We have focused on organic growth, maintenance of credit quality and recruiting and retaining experienced bankers with strong personal and professional relationships in their communities.

We serve the needs of commercial businesses and successful professionals and entrepreneurs located in Texas as well as operate several lines of business serving a regional or national clientele of commercial borrowers. We are primarily a secured lender, with a majority of our loans, other than our businesses with activities throughout the United States, to businesses headquartered or with operations in Texas. We have benefitted from the success of our business model since inception, producing strong loan growth and favorable loss experience amidst the challenging environment for banking nationally.

The Texas Market

The Texas market for banking services is highly competitive. Texas’ largest banking organizations are headquartered outside of Texas and are controlled by out-of-state organizations. We also compete with other providers of financial services, such as savings and loan associations, credit unions, consumer finance companies, securities firms, insurance companies, commercial finance and leasing companies, full service brokerage firms and discount brokerage firms. We believe that many middle market companies and successful professionals and entrepreneurs are interested in banking with a company headquartered in, and with decision-making authority based in, Texas and with established Texas bankers who have the expertise to act as trusted advisors to customers with regard to their banking needs. Our banking centers in our target markets are served by experienced bankers with lending expertise in the specific industries found in their market areas and established community ties. We believe our bank can offer customers more responsive and personalized service than our competitors. If we service these customers properly, we believe we will be able to establish long-term relationships and provide multiple products to our customers, thereby enhancing our profitability.

Business Strategy

Drawing on the business and community ties of our management and their banking experience, our strategy is to continue building an independent bank that focuses primarily on middle market business customers and successful professionals and entrepreneurs in each of the five major metropolitan markets of Texas. To achieve this, we seek to implement the following strategies:

• Targeting middle market businesses and successful professionals and entrepreneurs;

• Growing our loan and deposit base in our existing markets by hiring additional experienced bankers in our different lines of business;

• Continuing our emphasis on credit policy to maintain credit quality consistent with long-term objectives;

• Leveraging our existing infrastructure to support a larger volume of business;

• Maintaining stringent internal approval processes for capital and operating expenditures;

• Continuing our extensive use of outsourcing to provide cost-effective operational support and service levels consistent with large-bank operations; and

• Extending our reach within our target markets and lines of business through service innovation and service excellence.

Products and Services

We offer a variety of loan, deposit account and other financial products and services to our customers.

Business Customers.    We offer a full range of products and services oriented to the needs of our business customers, including:

• commercial loans for general corporate purposes including financing for working capital, internal growth, acquisitions and financing for business insurance premiums;

• real estate term and construction loans;

• mortgage finance lending;

• equipment leasing;

• treasury management services;

• wealth management and trust services; and

• letters of credit.

Individual Customers.    We also provide complete banking services for our individual customers, including:

• personal wealth management and trust services;

• certificates of deposit;

• interest-bearing and non-interest-bearing checking accounts with optional features such as Visa® debit/ATM cards and overdraft protection;

• traditional money market and savings accounts;

• loans, both secured and unsecured; and

• Internet banking.

Lending Activities

We target our lending to middle market businesses and successful professionals and entrepreneurs that meet our credit standards. The credit standards are set by our standing Credit Policy Committee with the assistance of our Bank’s Chief Credit and Risk Officer, who is charged with ensuring that credit standards are met by loans in our portfolio. Our Credit Policy Committee is comprised of senior Bank officers including our Bank’s Chief Executive Officer and President, our Texas President/Chief Lending Officer and our Bank’s Chief Credit and Risk Officer. We believe we have maintained a diversified loan portfolio. Credit policies and underwriting guidelines are tailored to address the unique risks associated with each industry represented in the portfolio. Our credit standards for commercial borrowers reference numerous criteria with respect to the borrower, including historical and projected financial information, strength of management, acceptable collateral and associated advance rates, and market conditions and trends in the borrower’s industry. In addition, prospective loans are also analyzed based on current industry concentrations in our loan portfolio to prevent an unacceptable concentration of loans in any particular industry. We believe our credit standards are consistent with achieving business objectives in the markets we serve and will generally mitigate risks. We believe that we differentiate our bank from its competitors by focusing on and aggressively marketing to our core customers and accommodating, to the extent permitted by our credit standards, their individual needs.

We generally extend variable rate loans in which the interest rate fluctuates with a predetermined indicator such as the United States prime rate or the London Interbank Offered Rate (LIBOR). Our use of variable rate loans is designed to protect us from risks associated with interest rate fluctuations since the rates of interest earned will automatically reflect such fluctuations.

Deposit Products

We offer a variety of deposit products to our core customers at interest rates that are competitive with other banks. Our business deposit products include commercial checking accounts, lockbox accounts, cash concentration accounts and other treasury management services, including an on-line system. Our treasury management on-line system offers information services, wire transfer initiation, ACH initiation, account transfer and service integration. Our consumer deposit products include checking accounts, savings accounts, money market accounts and certificates of deposit. We also allow our consumer deposit customers to access their accounts, transfer funds, pay bills and perform other account functions over the Internet and through ATM machines.

Wealth Management and Trust

Our wealth management and trust services include investment management, personal trust and estate services, custodial services, retirement accounts and related services. Our investment management professionals work with our clients to define objectives, goals and strategies for their investment portfolios. We assist the customer with the selection of an investment manager and work with the client to tailor the investment program accordingly. We also offer retirement products such as individual retirement accounts and administrative services for retirement vehicles such as pension and profit sharing plans.

Cayman Islands Branch

We established a branch of our bank in the Cayman Islands in 2003. We believe that a Cayman Islands branch enables us to offer more competitive cash management and deposit products to our customers. All deposits in the Cayman Branch come from U.S. based customers of our bank. Deposits, all of which are in U.S dollars, do not originate from foreign sources, funds transfers neither come from nor go to facilities outside of the U.S. and there are no federal or state income tax benefits to our bank or our customers as a result of these operations. Foreign deposits maintained at our Cayman Islands branch at December 31, 2014 and 2013 were $312.7 million and $330.3 million, respectively.

Employees

As of December 31, 2014, we had 1,142 full-time employees. None of our employees is represented by a collective bargaining agreement and we consider our relations with our employees to be good.

Regulation and Supervision

General.    We and our bank are subject to extensive federal and state laws and regulations that impose specific requirements on us and provide regulatory oversight of virtually all aspects of our operations. These laws and regulations generally are intended for the protection of depositors, the deposit insurance fund of the Federal Deposit Insurance Corporation (“FDIC”) and the stability of the U.S. banking system as a whole, rather than for the protection of our stockholders and creditors.

The following discussion summarizes certain laws and regulations to which we and our bank are subject. It does not address all applicable laws and regulations that affect us currently or might affect us in the future. This discussion is qualified in its entirety by reference to the full texts of the laws, regulations and policies described.

5

The Company’s activities are governed by the Bank Holding Company Act of 1956, as amended (“BHCA”), and is subject to regular inspection, examination and supervision by the Board of Governors of the Federal Reserve System (the “Federal Reserve”). We file quarterly reports and other information with the Federal Reserve. We file reports with the Securities and Exchange Commission (“SEC”) and are subject to its regulation with respect to our securities, reporting and certain governance matters, including matters submitted for stockholder approval. Our securities are listed on the Nasdaq Global Select Market, and we are subject to Nasdaq rules for listed companies.

Our bank is organized as a national banking association under the National Bank Act, and is subject to regulation, supervision and examination by the Office of the Comptroller of the Currency (the “OCC”), the FDIC, the Federal Reserve, the Consumer Financial Protection Bureau (“CFPB”) and other federal and state regulatory agencies. The OCC has primary supervisory responsibility for our bank and performs a continuous program of examinations concerning safety and soundness, the quality of management and directors, information technology and compliance with applicable laws and regulations. Our bank files quarterly reports of condition and income with the FDIC and other information with the OCC.

Bank holding company regulation.    The BHCA limits our business to banking, managing or controlling banks and other activities that the Federal Reserve has determined to be closely related to banking. We have elected to register with the Federal Reserve as a financial holding company. This authorizes us to engage in any activity that is either (i) financial in nature or incidental to such financial activity, as determined by the Federal Reserve, or (ii) complementary to a financial activity, so long as the activity does not pose a substantial risk to the safety and soundness of depository institutions or the financial system generally, as determined by the Federal Reserve. Examples of non-banking activities that are financial in nature include securities underwriting and dealing, insurance underwriting and making merchant banking investments.

We are not at this time exercising this authority at the parent company level. We and our bank engage in traditional banking activities that are deemed financial in nature. In order for us to undertake new activities permitted by the BHCA, we and our bank must be considered "well capitalized" (as defined below) and well managed, our bank must have received a rating of at least satisfactory in its most recent examination under the Community Reinvestment Act and we would be required to notify the Federal Reserve within thirty days of engaging in the new activity.

Under Federal Reserve policy, now codified by the Dodd-Frank Wall Street Reform and Consumer Protection Act ("Dodd-Frank Act"), we are expected to act as a source of financial and managerial strength to our bank and commit resources to its support. Such support may be required at times when, absent this Federal Reserve policy, a holding company may not be inclined to provide it. We could in certain circumstances be required to guarantee the capital plan of our bank if it became undercapitalized.

It is the policy of the Federal Reserve that financial holding companies may pay cash dividends on common stock only out of income available over the past year and only if prospective earnings retention is consistent with the organization’s expected future needs and financial condition. The policy provides that financial holding companies may not pay cash dividends in an amount that would undermine the holding company’s ability to serve as a source of strength to its banking subsidiary.

With certain limited exceptions, the BHCA prohibits a person or company or a group of persons deemed to be “acting in concert” from, directly or indirectly, acquiring more than 10% (5% if the acquirer is a bank holding company) of any class of our voting stock or obtaining the ability to control in any manner the election of a majority of our directors or otherwise direct the management or policies of our company without prior notice or application to and the approval of the Federal Reserve.

If, in the opinion of the applicable federal bank regulatory authorities, a depository institution or holding company is engaged in or is about to engage in an unsafe or unsound practice (which could include the payment of dividends), such authority may require, generally after notice and hearing, that such institution or holding company cease and desist such practice. The federal banking agencies have indicated that paying dividends that deplete a depository institution’s or holding company’s capital base to an inadequate level would be such an unsafe or unsound banking practice. Moreover, the Federal Reserve and the FDIC have issued policy statements providing that financial holding companies and insured depository institutions generally should only pay dividends out of current operating earnings.

Regulation of our bank.    National banks such as our bank are subject to examination by the OCC and the CFPB, and to a lesser extent by the FDIC. The OCC and the FDIC regulate or monitor all areas of a national bank’s operations, including security devices and procedures, adequacy of capitalization and loss reserves, accounting treatment and impact on capital determinations, loans, investments, borrowings, deposits, liquidity, mergers, issuances of securities, payment of dividends, interest rate risk management, 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 OCC requires national banks to maintain capital ratios and imposes limitations on their aggregate investment in real estate, bank premises and furniture and fixtures. National banks are required by the OCC to file quarterly reports of their financial condition and results of operations and to conduct an annual audit of their financial statements in compliance with minimum standards and procedures prescribed by the OCC.

Capital Adequacy Requirements.    Federal banking regulators have adopted a system using risk-based capital guidelines to evaluate the capital adequacy of banks and bank holding companies that is based upon the 1988 capital accord of the Bank for International Settlements’ Committee on Banking Supervision (the “Basel Committee”), a committee of central banks and bank regulators from the major industrialized countries that coordinates international standards for bank regulation. Under the guidelines, specific categories of assets and off-balance-sheet activities such as letters of credit are assigned risk weights, based generally on the perceived credit or other risks associated with the asset. Off-balance-sheet activities are assigned a credit conversion factor based on the perceived likelihood that they will become on-balance-sheet assets. These risk weights are multiplied by corresponding asset balances to determine a “risk weighted” asset base which is then measured against various measures of capital to produce capital ratios.

An organization’s capital is classified in one of two tiers, Core Capital, or Tier 1, and Supplementary Capital, or Tier 2. Tier 1 capital includes common stock, retained earnings, qualifying non-cumulative perpetual preferred stock, minority interests in the equity of consolidated subsidiaries, a limited amount of qualifying trust preferred securities and qualifying cumulative perpetual preferred stock at the holding company level, less goodwill and most intangible assets. Tier 2 capital includes perpetual preferred stock and trust preferred securities not meeting the Tier 1 definition, mandatory convertible debt securities, subordinated debt, and allowances for loan and lease losses. Each category is subject to a number of regulatory definitional and qualifying requirements.

We and our bank are required to maintain a minimum total risk-based capital ratio of 8% (of which at least 4% is required to consist of Tier 1 capital elements). Tier 1 and total capital ratios must be at least 6.0% and 10.0% on a risk-adjusted basis, respectively, for an institution to be considered well capitalized.

Our bank’s total risk-based capital ratio was 10.57% at December 31, 2014 and, as a result, it is currently classified as “well capitalized” for purposes of the OCC’s prompt corrective action regulations.

The bank’s capital category of “well capitalized” is determined solely for the purposes of applying the prompt corrective action regulations. The regulatory capital category may not constitute an accurate representation of the bank’s overall financial condition or prospects. Our regulatory capital status is addressed in more detail under the heading “Liquidity and Capital Resources” within Management’s Discussion and Analysis of Financial Condition and Results of Operations and in Note 13 to our financial statements—Regulatory Restrictions.

The Federal Deposit Insurance Corporation Improvement Act of 1991 (“FDICIA”) sets forth five capital categories for insured depository institutions under the prompt corrective action regulations:

• Well capitalized—equals or exceeds a 10% total risk-based capital ratio, 6% Tier 1 risk-based capital ratio, and 5% leverage ratio and is not subject to any written agreement, order or directive requiring it to maintain a specific level for any capital measure;

• Adequately capitalized—equals or exceeds an 8% total risk-based capital ratio, 4% tier 1 risk-based capital ratio, and 4% leverage ratio;

• Undercapitalized—total risk-based capital ratio of less than 8%, or a tier 1 risk-based ratio of less than 4%, or a leverage ratio of less than 4% (3% for institutions with a regulatory rating of 1 that do not evidence rapid growth or other heightened risk indicators);

• Significantly undercapitalized—total risk-based capital ratio of less than 6%, or a tier 1 risk-based capital ratio of less than 3%, or a leverage ratio of less than 3%; and

• Critically undercapitalized—a ratio of tangible equity to total assets equal to or less than 2%.

Federal bank regulatory agencies are required to implement arrangements for “prompt corrective action” for institutions failing to meet minimum requirements to be at least adequately capitalized. FDICIA imposes an increasingly stringent array of restrictions, requirements and prohibitions as an organization’s capital levels deteriorate. A significantly undercapitalized institution is subject to mandated capital raising activities, restrictions on interest rates paid and transactions with affiliates, removal of management and other restrictions. The OCC has only very limited discretion in dealing with a critically undercapitalized institution and is virtually required to appoint a receiver or conservator (the FDIC) if the capital deficiency is not corrected promptly.

Under the Federal Deposit Insurance Act (“FDIA”), “critically undercapitalized” banks may not, beginning 60 days after becoming critically undercapitalized, make any payment of principal or interest on their subordinated debt (subject to certain limited exceptions). In addition, under Section 18(i) of the FDIA, banks are required to obtain the advance consent of the FDIC to retire any part of their subordinated notes. “Critically undercapitalized” banks are also subject to the appointment of a conservator or receiver. Under the FDIA, a bank may not pay interest on its subordinated notes if such interest is required to be paid only out of net profits, or distribute any of its capital assets, while it remains in default on any assessment due to the FDIC.

Federal bank regulators may set capital requirements for a particular banking organization that are higher than the minimum ratios when circumstances warrant. Federal Reserve and OCC guidelines provide that banking organizations experiencing significant internal growth or making acquisitions will be expected to maintain strong capital positions substantially above the minimum supervisory levels, without significant reliance on intangible assets. Concentration of credit risks arising from non-traditional activities, as well as an institution’s ability to manage these risks, are important factors taken into account by regulatory agencies in assessing an organization’s overall capital adequacy.

The OCC and the Federal Reserve also use a leverage ratio as an additional tool to evaluate the capital adequacy of banking organizations. The leverage ratio is a company’s Tier 1 capital divided by its average total consolidated assets. A minimum leverage ratio of 3.0% is required for banks and bank holding companies that either have the highest supervisory rating or have implemented the appropriate federal regulatory authority’s risk-adjusted measure for market risk. All other banks and bank holding companies are required to maintain a minimum leverage ratio of 4.0%, unless a different minimum is specified by an appropriate regulatory authority. In order to be considered well capitalized the leverage ratio must be at least 5.0%. Most organizations seek to maintain leverage ratios that are at least 100 to 200 basis points above the minimum ratio.

Our bank’s leverage ratio was 9.75% at December 31, 2014 and, as a result, it is currently classified as “well capitalized” for purposes of the OCC’s prompt corrective action regulations.

The risk-based and leverage capital ratios established by federal banking regulators are minimum supervisory ratios generally applicable to banking organizations that meet specified criteria, assuming that they otherwise have received the highest regulatory ratings in their most recent examinations. Banking organizations not meeting these criteria are expected to operate with capital positions in excess of the minimum ratios. Regulators can, from time to time, change their policies or interpretations of banking practices to require changes in risk weights, which may require the bank to obtain additional capital to support future growth or reduce asset balances in order to meet minimum acceptable capital ratios.

Basel III.    The Basel Committee in 2010 released a set of recommendations for strengthening international capital and liquidity regulation of banking organizations, known as Basel III. In June 2012, U.S. bank regulatory agencies, including the OCC, issued three proposals to implement the capital, liquidity and other requirements under Basel III, as well as certain other regulatory capital requirements under the Dodd-Frank Act. In July 2013, the Federal Reserve published final rules for the adoption of the Basel III regulatory capital framework (the “Basel III Capital Rules”).

The Basel III Capital Rules, among other things, (i) introduce a new capital measure called “Common Equity Tier 1,” (ii) specify that Tier 1 capital consist of Common Equity Tier 1 and “Additional Tier 1 Capital” instruments meeting specified requirements, (iii) define Common Equity Tier 1 narrowly by requiring that most deductions/adjustments to regulatory capital measures be made to Common Equity Tier 1 and not to the other components of capital and (iv) establish a 7% threshold for the Tier 1 common equity ratio, consisting of a minimum level plus a capital conservation buffer, and (v) expand the scope of the deductions/adjustments as compared to existing regulations. The rule also changes both the Tier 1 risk-based capital requirements and the total risk-based requirements to a minimum of 6% and 8%, respectively, plus a capital conservation buffer of 2.5% totaling 8.5% and 10.5%, respectively. The leverage ratio requirement under the rule is 5%. In order to be well capitalized under the new rule, we must maintain a common equity Tier 1 capital ratio, Tier 1 capital ratio, and total capital ratio of greater than or equal to 6.5%, 8% and 10%, respectively.

Because we had less than $15 billion in total consolidated assets as of December 31, 2009, we are allowed to continue to classify our trust preferred securities, all of which were issued prior to May 19, 2010, as Tier 1 capital.

The Basel III Capital Rules became effective for us on January 1, 2015 with certain transition provisions fully phased in on January 1, 2019. Based on our assessment of the Basel III Capital Rules, we do not believe they will have a material impact on the Company or our Bank. We believe we will meet the capital adequacy requirements under the Basel III Capital Rules on a fully phased-in basis when we commence filing 2015 reports with the FDIC and OCC. Regulators may change capital and liquidity requirements including previous interpretations of practices related to risk weights that could require an increase to the allocation of capital to assets held by our bank, and they could require banks to make retroactive adjustments to financial statements to reflect such changes.

8

Liquidity Requirements.    The Basel III proposal included a liquidity framework that would require banks and bank holding companies to measure their liquidity against specific liquidity tests. U.S. bank regulators in September 2014 issued a final rule implementing the Basel III liquidity framework for certain U.S. banks - generally those that have more than $50 billion of assets or whose primary federal banking regulator determines compliance with the liquidity framework is appropriate based on the organization's size, level of complexity, risk profile, scope of operations, U.S. or non-U.S. affiliations, or risk to the financial system. One of the liquidity tests included in the new rule, referred to as the liquidity coverage ratio (“LCR”), is designed to ensure that a banking entity maintains an adequate level of unencumbered high-quality liquid assets equal to the entity’s expected net cash outflow for a 30-day time horizon (or, if greater, 25% of its expected total cash outflow) under an acute liquidity stress scenario. The other test, referred to as the net stable funding ratio (“NSFR”), is designed to promote more medium- and long-term funding of the assets and activities of banking entities over a one-year time horizon. These requirements are predicted to encourage the covered banking entities to increase their holdings of U.S. Treasury securities and other sovereign debt as a component of assets, and also to increase the use of long-term debt as a funding source. Regulators may change capital and liquidity requirements including previous interpretations of practices related to risk weights that could require an increase to the allocation of capital to assets held by our bank, and they could require banks to make retroactive adjustments to financial statements to reflect such changes.

Restrictions on Dividends and Repurchases.    The sole source of funding of our parent company financial obligations has consisted of proceeds of capital markets transactions and cash payments from our bank for debt service and dividend payments with respect to our bank's preferred stock issued to the Company. We may in the future seek to rely upon receipt of dividends paid by our bank to meet our financial obligations. Our bank is subject to statutory dividend restrictions. Under such restrictions, national banks may not, without the prior approval of the OCC, declare dividends in excess of the sum of the current year’s net profits plus the retained net profits from the prior two years, less any required transfers to surplus. The Basel III Capital Rules, effective for us on January 1, 2015, further limit the amount of dividends that may be paid by our bank. In addition, under the FDICIA, our bank may not pay any dividend if payment would cause it to become undercapitalized or if it is undercapitalized.

Stress Testing.    Pursuant to the Dodd-Frank Act and regulations published by the Federal Reserve and OCC in October 2012, institutions with average total consolidated assets greater than $10 billion are required to conduct an annual “stress test” of capital and consolidated earnings and losses under a base case and at least two stress scenarios provided by bank regulatory agencies. We became subject to this requirement in 2014 and have developed dedicated staffing, economic models, policies and procedures to implement stress testing with respect to data as of September 30, 2014, using scenarios released by the agencies in November 2014. The results of our stress testing must be reported to the agencies in March 2015. Public disclosure of our summary stress test results will be made in June 2015. Results of stress test calculations are anticipated to become an important factor considered by banking regulators in evaluating a range of banking practices.

Transactions with Affiliates and Insiders.    Our bank is subject to Section 23A of the Federal Reserve Act which places limits on, among other covered transactions, the amount of loans or extensions of credit to affiliates that may be made by our bank. Extensions of credit to affiliates must be adequately collateralized by specified amounts and types of collateral. Section 23A also limits the amount of loans or advances by our bank to third party borrowers which are collateralized by our securities or obligations or those of our subsidiaries. Our bank also is subject to Section 23B of the Federal Reserve Act, which, among other things, prohibits an institution from engaging in transactions with 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 non-affiliates.

We are subject to restrictions on extensions of credit to executive officers, directors, principal stockholders and their related interests. These restrictions are contained in the Federal Reserve Act and Federal Reserve Regulation O and apply to all insured institutions as well as their subsidiaries and holding companies. These restrictions include limits on loans to one borrower and conditions that must be met before such loans can be made. There is also an aggregate limitation on all loans to insiders and their related interests, which cannot exceed the institution’s total unimpaired capital and surplus, unless the FDIC determines that a lesser amount is appropriate. Insiders are subject to enforcement actions for knowingly accepting loans in violation of applicable restrictions. Additional restrictions on transactions with affiliates and insiders are discussed in the Dodd-Frank Act section.

Gramm-Leach-Bliley Financial Modernization Act of 1999 ("Gramm-Leach Bliley Act").    The Gramm-Leach-Bliley Act:

• allows bank holding companies meeting management, capital and Community Reinvestment Act standards to engage in a substantially broader range of non-banking activities than was permissible prior to enactment, including insurance underwriting and making merchant banking investments in commercial and financial companies;

• allows insurers and other financial services companies to acquire banks;

• removes various restrictions that applied to bank holding company ownership of securities firms and mutual fund advisory companies; and

• establishes the overall regulatory structure applicable to bank holding companies that also engage in insurance and securities operations.

The Gramm-Leach-Bliley Act also modifies other current financial laws, including laws related to financial privacy. The financial privacy provisions generally prohibit financial institutions, including us, from disclosing non-public personal financial information to non-affiliated third parties unless customers have the opportunity to “opt out” of the disclosure.

Community Reinvestment Act.    The Community Reinvestment Act of 1977 (“CRA”) requires depository institutions to assist in meeting the credit needs of their market areas consistent with safe and sound banking practice. Under the CRA, each depository institution is required to help meet the credit needs of its market areas by, among other things, providing credit to low- and moderate-income individuals and communities. Depository institutions are periodically examined for compliance with the CRA and are assigned ratings. In order for a financial holding company to commence new activity permitted by the BHCA, each insured depository institution subsidiary of the financial holding company must have received a rating of at least “satisfactory” in its most recent examination under the CRA.

The USA Patriot Act, the International Money Laundering Abatement and Financial Anti-Terrorism Act and the Bank Secrecy Act.    A major focus of U.S. government policy regarding financial institutions in recent years has been combating money laundering, terrorist financing and other illegal payments. The USA Patriot Act of 2001 and the International Money Laundering Abatement and Financial Anti-Terrorism Act of 2001 substantially broadened the scope of United States anti-money laundering laws and penalties, specifically related to the Bank Secrecy Act of 1970, and expanded the extra-territorial jurisdiction of the U.S. government in this area. Regulations issued under these laws impose obligations on financial institutions to maintain appropriate policies, procedures and controls to detect, prevent and report money laundering and terrorist financing and to verify the identity of their customers. Failure of a financial institution to maintain and implement adequate programs to combat money laundering and terrorist financing, or to comply with relevant laws or regulations, could have serious legal, reputational and financial consequences for the institution. Because of the significance of regulatory emphasis on these requirements, we will continue to expend significant staffing, technology and financial resources to maintain programs designed to ensure compliance with applicable laws and regulations and an effective audit function for testing our compliance with the Bank Secrecy Act on an ongoing basis.

The Volcker Rule.    The Dodd-Frank Act amended the BHCA to require the federal financial regulatory agencies to adopt rules that prohibit banks and their affiliates from engaging in proprietary trading in designated types of financial instruments and investing in and sponsoring certain unregistered investment companies. This statutory provision, commonly known as the “Volcker Rule,” defines unregistered investment companies as hedge funds and private equity funds. In December 2013, federal regulators finalized rules to implement the Volcker Rule. The final rule is highly complex, and many aspects of its application remain uncertain. We do not currently anticipate that the Volcker Rule will have a material effect on our operations since we do not engage in the businesses prohibited by the Volcker Rule. Unanticipated effects of the Volcker Rule’s provisions or future interpretations may have an adverse effect on our business or services provided to our bank by other financial institutions.

Safe and Sound Banking Practices.    Banks and bank holding companies are prohibited from engaging in unsafe and unsound banking practices. Bank regulators have broad authority to prohibit activities of bank holding companies and their subsidiaries which represent unsafe and unsound banking practices or which constitute violations of laws or regulations, and have considerable discretion in identifying what they deem to be unsafe and unsound practices. Regulators can assess civil money penalties for certain activities based upon finding unsafe and unsound conduct on a knowing and reckless basis, if those activities cause a substantial loss to a depository institution. The penalties can be as high as $1.0 million for each day the activity continues.

Consumer Financial Protection Bureau.    The Dodd-Frank Act established the CFPB, which has supervisory authority over depository institutions with total assets of $10 billion or greater with respect to a long list of statutes protecting the interests of consumers of financial services. The CFPB has to date focused its supervision and regulatory efforts on (i) risks to consumers and compliance with the federal consumer financial laws, when it evaluates the policies and practices of a financial institution; (ii) the markets in which firms operate and risks to consumers posed by activities in those markets; and (iii) depository institutions that offer a wide variety of consumer financial products and services.

10

Limits on Compensation.    The Federal Reserve, OCC and FDIC in 2010 issued comprehensive final guidance on incentive compensation policies for executive management of banks and bank holding companies. This guidance was intended to ensure that the incentive compensation policies of banking organizations do not undermine their safety and soundness by encouraging excessive risk-taking. The objective of the guidance is to assure that incentive compensation arrangements (i) provide incentives that do not encourage excessive risk-taking, (ii) are compatible with effective internal controls and risk management and (iii) are supported by strong corporate governance, including oversight by the board of directors.

The Dodd-Frank Act.    The Dodd-Frank Act became law in 2010. It has already had a broad impact on the financial services industry, imposing significant regulatory and compliance changes. A significant volume of financial services regulations required by the Dodd-Frank Act have not yet been proposed, or if proposed, have not yet been finalized by banking regulators, making it difficult to predict the ultimate effect of the Dodd-Frank Act. The following discussion provides a brief summary of certain provisions of the Dodd-Frank Act that may have an effect on us.

The Dodd-Frank Act significantly reduces the ability of national banks to rely upon federal preemption of state consumer financial laws. Although the OCC, as the primary regulator of national banks, will have the ability to make preemption determinations where certain conditions are met, the broad rollback of federal preemption has the potential to create a patchwork of federal and state compliance obligations and enforcement. This could, in turn, result in significant new regulatory requirements applicable to us and certain of our lending activities, with potentially significant changes in our operations and increases in our compliance costs.

The Dodd-Frank Act made permanent the general $250,000 deposit insurance limit for insured deposits. Amendments to the FDIA also revised the assessment base against which an insured depository institution’s deposit insurance premiums paid to the FDIC’s deposit insurance fund (“DIF”) are calculated. The assessment base now consists of average consolidated total assets less average tangible equity. Additionally, the Dodd-Frank Act made changes to the minimum designated reserve ratio of the DIF, increasing the minimum from 1.15% to 1.35% of the estimated amount of total insured deposits, and eliminating the requirement that the FDIC pay dividends to depository institutions when the reserve ratio exceeds certain thresholds. These changes contributed to an increase in the FDIC deposit insurance premiums paid by us in 2014 and may contribute to increasing and less predictable deposit insurance expense in future years.

The Dodd-Frank Act generally enhances the restrictions on transactions with affiliates under Sections 23A and 23B of the Federal Reserve Act, including an expansion of the definition of “covered transactions” and an increase in the amount of time for which collateral requirements regarding covered credit transactions must be satisfied. Insider transaction limitations are expanded through the strengthening of loan restrictions to insiders and the expansion of the types of transactions subject to the various limits, including derivatives transactions, repurchase agreements, reverse repurchase agreements and securities lending or borrowing transactions. Restrictions are also placed on certain asset sales to and from an insider to an institution, including requirements that such sales be on market terms and, in certain circumstances, approved by the institution’s board of directors.

The Dodd-Frank Act may create risks of “secondary actor liability” for lenders that provide financing to entities offering financial products to consumers. We may incur compliance and other costs in connection with administration of credit extended to entities engaged in activities covered by the Dodd-Frank Act.

The Dodd-Frank Act addresses many investor protection, corporate governance and executive compensation matters that affect most U.S. publicly traded companies, including ours. The Dodd-Frank Act (1) grants stockholders of U.S. publicly traded companies an advisory vote on executive compensation; (2) enhances independence requirements for compensation committee members; (3) requires companies listed on national securities exchanges to adopt incentive-based compensation claw-back policies for executive officers; (4) provides the SEC with authority to adopt proxy access rules that would allow stockholders of publicly traded companies to nominate candidates for election as a director and have those nominees included in a company’s proxy materials; (5) prohibits uninstructed broker votes on election of directors, executive compensation matters (including say on pay advisory votes), and other significant matters, and (6) requires disclosures regarding board leadership structure.

Given the uncertainty associated with the manner in which the provisions of the Dodd-Frank Act will be implemented by the various regulatory agencies and through regulations, the full extent of the impact such requirements will have on our operations is unclear. The changes resulting from the Dodd-Frank Act may impact the profitability of our business activities, require changes to certain of our business practices, impose upon us more stringent capital, liquidity and leverage requirements or otherwise adversely affect our business. These changes may also require us to invest significant management attention and resources to evaluate and make any changes necessary to comply with new statutory and regulatory requirements.

ITEM 1A. RISK FACTORS

Our business is subject to risk. The following discussion, along with management’s discussion and analysis and our financial statements and footnotes, sets forth the most significant risks and uncertainties that we believe could adversely affect our business, financial condition or results of operations. Additional risks and uncertainties that management is not aware of or that management currently deems immaterial may also have a material adverse effect on our business, financial condition or results of operations. There is no assurance that this discussion covers all potential risks that we face. The occurrence of the described risks could cause our results to differ materially from those described in our forward-looking statements included elsewhere in this report, and could have a material adverse impact on our business or results of operations.

Risk Factors Associated With Our Business

We must effectively manage our credit risk.    The risk of non-payment of loans is inherent in commercial banking. Increased credit risk may result from several factors, including adverse changes in local, U.S. and global economic and industry conditions, declines in the value of collateral, concentrations of credit associated with specific loan categories, industries or collateral types and risks related to individual borrowers. We rely heavily on information provided by third parties when originating and monitoring loans. If this information is intentionally or negligently misrepresented and we do not detect such misrepresentations, the credit risk associated with the transaction may be increased. Although we attempt to manage our credit risk by carefully monitoring the concentration of our loans within specific loan categories and industries and through prudent loan approval and monitoring practices in all categories of our lending, we cannot assure you that our approval and monitoring procedures will reduce these lending risks. If our credit administration personnel, policies and procedures are not able to adequately adapt to changes in economic or other conditions that affect customers and the quality of the loan portfolio, we may incur increased losses that could adversely affect our financial results.

A significant portion of our assets consists of commercial loans. We generally invest a greater proportion of our assets in commercial loans to business customers than other banking institutions of our size, and our business plan calls for continued efforts to increase our assets invested in these loans. At December 31, 2014, approximately 41% of our loan portfolio was comprised of commercial loans. Commercial loans may involve a higher degree of credit risk than other types of loans due, in part, to their larger average size, the effects of changing economic conditions on the businesses of our commercial loan customers, the dependence of borrowers on operating cash flow to service debt and our reliance upon collateral which may not be readily marketable. Due to the proportion of these commercial loans in our portfolio and because the balances of these loans are, on average, larger than other categories of loans, losses incurred on a relatively small number of commercial loans could have a materially adverse impact on our results of operations and financial condition.

A significant portion of our loans are secured by commercial and residential real estate. At December 31, 2014, approximately 30% of our loan portfolio was comprised of loans with real estate as the primary component of collateral. Our real estate lending activities, and our exposure to fluctuations in real estate collateral values, are significant and expected to increase as our assets increase. The market value of real estate can fluctuate significantly in a relatively short period of time as a result of market conditions in the geographic area in which the real estate is located. If the value of real estate serving as collateral for our loans declines materially, a significant part of our loan portfolio could become under-collateralized and losses incurred upon borrower defaults would increase. Conditions in certain segments of the real estate industry, including homebuilding, lot development and mortgage lending, may have an effect on values of real estate pledged as collateral for our loans. The inability of purchasers of real estate, including residential real estate, to obtain financing may weaken the financial condition of our borrowers who are dependent on the sale or refinancing of property to repay their loans. Changes in the economic health of certain industries can have a significant impact on other sectors or industries which are both directly and indirectly associated with the industry.

Our business is concentrated in Texas; Energy industry exposure. A substantial majority of our customers are located in Texas. As a result, our financial condition and results of operations may be strongly affected by any prolonged period of economic recession or other adverse business, economic or regulatory conditions affecting Texas businesses and financial institutions. While Texas is a more diversified economy than it was in the 1980’s, the energy sector continues to be an important part of the Texas economy. Approximately 7% of our total loans at December 31, 2014, were to borrowers engaged in exploration and production, transportation and processing of oil and natural gas and companies providing oilfield and related energy industry

12

services. These businesses can be significantly affected by volatility in oil and natural gas prices and material declines in the level of drilling and production activity in Texas and in other areas of the United States. Adverse developments in the energy sector can have significant spillover effects on the Texas economy, including commercial and residential real estate values and the general level of economic activity. We are carefully monitoring the impact of the recent significant declines in oil and natural gas prices and drilling activity on our loan portfolio, and have reflected these events in the determination of our allowance for loan and lease losses as of December 31, 2014. There is no assurance that we will not be adversely impacted by the direct and indirect effects of current and future conditions in the energy industry in Texas and nationally.

Our future profitability depends, to a significant extent, upon our middle market business customers. Our future profitability depends, to a significant extent, upon revenue we receive from middle market business customers, and their ability to continue to meet their loan obligations. Adverse economic conditions or other factors affecting this market segment may have a greater adverse effect on us than on other financial institutions that have a more diversified customer base.

We must maintain an adequate allowance for loan losses. Our experience in the banking industry indicates that some portion of our loans will become delinquent, and some may only be partially repaid or may never be repaid at all. We maintain an allowance for loan losses, which is a reserve established through a provision for loan losses charged to expense each quarter, that is consistent with management’s assessment of the collectability of the loan portfolio in light of the amount of loans committed and outstanding and current economic conditions and market trends. When specific loan losses are identified, the amount of the expected loss is removed, or charged-off, from the allowance. Our methodology for establishing the adequacy of the allowance for loan losses depends on our subjective application of risk grades as indicators of each borrower’s ability to repay specific loans, together with our assessment of how actual or projected changes in competitor underwriting practices, competition for borrowers and depositors and other conditions in our markets are likely to impact improvement or deterioration in the collectability of our loans as compared to our historical experience.

Our business model makes our bank more vulnerable to changes in underlying business credit quality than other banks with which we compete. We have a substantially larger percentage of commercial, real estate and other categories of loans relative to total assets than most other banks in our market. We have a substantially smaller portion of securities and other earning assets categories that can be less vulnerable to changes in local, regional or industry-specific economic trends, causing our potential for credit losses to be more severe than other banks. Our business model has focused on growth in various loan categories that can be more sensitive to changes in the economic trends. We believe our ability to maintain above-peer rates of growth in commercial loans is dependent on maintaining above-peer credit quality metrics. The failure to do so would have a material adverse impact on our growth and profitability.

If our assessment of future losses is inaccurate, or economic and market conditions or our borrower’s financial performance experience material unanticipated changes, the allowance may become inadequate, requiring larger provisions for loan losses that can materially decrease our earnings. Certain of our loans individually represent a significant percentage of our total allowance for loan losses. Adverse collection experience in a relatively small number of these loans could require an increase in the provision for loan losses. Federal regulators periodically review our allowance for loan losses and, based on their judgments, which may be different than ours, may require us to change classifications or grades of loans, increase the allowance for loan losses and recognize further loan charge-offs. Any increase in the allowance for loan losses or in the amount of loan charge-offs required by these regulatory agencies could have a negative effect on our results of operations and financial condition.

We must effectively manage our interest rate risk. Our profitability is dependent to a large extent on our net interest income, which is the difference between the interest income paid to us on our loans and investments and the interest we pay to third parties such as our depositors, lenders and debtholders. Changes in interest rates can impact our profits and the fair values of certain of our assets and liabilities. We have experienced a prolonged period of unusually low interest rates, which have had an adverse effect on our earnings by reducing yields on loans and other earning assets. A continued low rate environment will continue to place downward pressure on our net interest income. Increases in market interest rates may reduce our customers' desire to borrow money from us or adversely affect their ability to repay their outstanding loans by increasing their debt service obligations through the periodic reset of adjustable interest rate loans. If our borrowers’ ability to pay their loans is impaired by increasing interest payment obligations, our level of non-performing assets would increase, producing an adverse effect on operating results.

Increases in interest rates and economic conditions affecting consumer demand for housing can have a material impact on the volume of mortgage originations and refinancings, adversely affecting the profitability of our mortgage finance business. Interest rate risk can also result from mismatches between the dollar amounts of repricing or maturing assets and liabilities and from mismatches in the timing and rates at which our assets and liabilities reprice. We actively monitor and manage the balances of our maturing and repricing assets and liabilities to reduce the adverse impact of changes in interest rates, but there can be no assurance that we will be able to avoid material adverse effects on our net interest margin in all market conditions.

Federal prohibitions on the ability of financial institutions to pay interest on demand deposit accounts were repealed in 2011 by the Dodd-Frank Act. This change has had limited impact to date due to the excess of commercial liquidity and the low interest

13

rate environment in recent years. There can be no assurance that we will not be materially adversely affected in the future if economic activity increases and interest rates rise, which may result in our interest expense increasing, with a commensurate effect on our net interest income, if we must offer interest on demand deposits to attract or retain customer deposits.

We must effectively execute our business strategy in order to continue our asset and earnings growth. Our core strategy is to develop our business principally through organic growth. Our prospects for continued growth must be considered in light of the risks, expenses and difficulties frequently encountered by companies seeking to realize significant growth. In order to execute our growth strategy successfully, we must, among other things:

• continue to identify and expand into suitable markets and lines of business, in Texas, regionally and nationally;

• develop new products and services and execute our full range of products and services more efficiently and effectively;

• attract and retain qualified bankers in each of our targeted markets to build our customer base;

• respond to market opportunities promptly and nimbly while balancing the demands of risk management and compliance with regulatory requirements;

• expand our loan portfolio while maintaining credit quality;

• attract sufficient deposits and capital to fund our anticipated loan growth and satisfy regulatory requirements;

• control expenses; and

• acquire and maintain sufficient qualified staffing and information technology and operational infrastructure to support growth and compliance with increasing and changing regulatory requirements.

Failure to effectively execute our business strategy could have a material adverse effect on our business, future prospects, financial condition or results of operations.Our past achievement of safe and sound balance sheet growth, even during difficult years such as the period of 2008-2010, provides no assurance of comparable future success.

We must be effective in developing and executing new lines of business and new products and services while managing associated risks. Our business strategy requires that we develop and grow new lines of business and offer new products and services within existing lines of business in order to compete successfully and realize our growth objectives for both loans and deposits to fund them. Substantial costs, risks and uncertainties are associated with these efforts, particularly in instances where the markets are not fully developed. Developing and marketing new activities requires that we invest significant time and resources before revenues and profits can be realized. Timetables for the development and launch of new activities may not be achieved and price and profitability targets may not prove feasible. External factors, such as compliance with regulations, receipt of necessary licenses or permits, competitive alternatives and shifting market preferences, may also adversely impact the successful execution of new activities. New activities necessarily entail additional risks and may present additional risks to the effectiveness of our system of internal controls. All service offerings, including current offerings and new activities, may become more risky due to changes in economic, competitive and market conditions beyond our control. Our regulators could determine that our risk management practices are not adequate and take action to restrain our growth. Failure to successfully manage these risks, generally and to the satisfaction of our regulators, in the development and implementation of new lines of business or new products or services could have a material adverse effect on our business, results of operations and financial condition.

Our growth plans are dependent on the availability of capital and funding. Our historical ability to raise capital through the sale of capital stock and debt securities may be affected by economic and market conditions or regulatory changes that are beyond our control. Adverse changes in our operating performance or financial condition could make raising additional capital difficult or more expensive or limit our access to customary sources of funding, including inter-bank borrowings, repurchase agreements and borrowings from the Federal Reserve Bank or the Federal Home Loan Bank. Unexpected changes in requirements for regulatory capital resulting from regulatory actions or the results of our Dodd-Frank Act stress testing could require us to raise capital at a time, and at a price, that might be unfavorable, or require that we forego continuing growth or shrink our balance sheet. We cannot offer assurance that sufficient capital and funding will be available to us in the future, in needed amounts, upon acceptable terms or at all. Our efforts to raise capital could require the issuance of securities at times and with maturities, conditions and rates that are disadvantageous, and which could have a dilutive impact on our current stockholders. Factors that could adversely affect our ability to raise additional capital include conditions in the capital markets, our financial performance, regulatory actions and general economic conditions. Increases in our cost of capital, including increased interest or dividend requirements, could have a direct adverse impact on our operating performance and our ability to achieve our growth objectives. Trust preferred securities are no longer viable as a source of new long-term debt capital as a result of regulatory changes. The treatment of our existing trust preferred securities as capital may be subject to further regulatory change prior to their maturity, which could require the Company to seek additional capital.

We must effectively manage our liquidity risk. Our bank requires available funds (liquidity) to meet its deposit, debt and other obligations as they come due, borrower requests to draw on committed credit facilities as well as unexpected demands for cash

14

payments. While we are not subject to Basel III liquidity regulations, the adequacy of our liquidity is a matter of regulatory interest given the significant portion of our balance sheet represented by loans as opposed to securities and other more marketable investments. Our bank’s principal source of funding consists of customer deposits. A substantial majority of our bank’s liabilities consist of demand, savings, interest checking and money market deposits, which are payable on demand or upon several days’ notice. By comparison, a substantial portion of our assets are loans, most of which, excluding our mortgage finance loans, cannot be collected or sold in so short a time frame, creating the potential for an imbalance in the availability of liquid assets to satisfy depositors and loan funding requirements.

We hold smaller balances of marketable securities than many of our competitors, limiting our ability to increase our liquidity by completing market sales of these assets. An inability to raise funds through deposits, borrowings, the sale of securities and loans and other sources, including our access to capital market transactions, could have a substantial negative effect on our bank’s liquidity. We actively manage our available sources of funds to meet our expected needs under normal and financially stressed conditions, but there is no assurance that our bank will be able to make new loans, meet ongoing funding commitments to borrowers and replace maturing deposits and advances as necessary under all possible circumstances. Our bank’s ability to obtain funding could be impaired by factors beyond its control, such as disruptions in financial markets, negative expectations regarding the financial services industry generally or in our markets or negative perceptions of our bank.

Our mortgage finance business has experienced, and will likely continue to experience, highly variable usage of our funding capacity resulting from seasonal demands for credit, surges in consumer demand driven by changes in interest rates and month-end “spikes” of residential mortgage closings. We have responded to these variable funding demands by, among other things, increasing the extent of participations sold in our mortgage loan interests and by opening an expanded borrowing relationship with the Federal Home Loan Bank in the fourth quarter of 2014. Our mortgage finance customers have in recent periods provided significant low-cost deposit balances associated with the borrower escrow accounts created at the time certain mortgage loans are funded, which have benefitted our liquidity and net interest margin. Individual escrow account balances also experience significant variability during the year as ad valorem taxes and insurance premiums are paid periodically. While the short average holding period of our mortgage interests of approximately 20 days will allow us, if necessitated by a funding shortfall, to rapidly decrease the size of the portfolio and its associated funding requirements, any such action might significantly damage business relationships important to that business.

Our bank sources a significant volume of its demand deposits from financial services companies, mortgage finance customers and other commercial sources, resulting in a larger percentage of larger deposits and a smaller number of sources of deposits than would be typical of other banks in our markets. In recent periods over half of our total deposits have been attributable to customers whose balances exceed the $250,000 FDIC insurance limit. Many of these customers actively monitor our financial condition and results of operations and could withdraw their deposits quickly upon the occurrence of a material adverse development affecting our bank. One potential source of liquidity for our bank consists of “brokered deposits” arranged by brokers acting as intermediaries, typically larger money-center financial institutions. We receive deposits provided by certain of our customers in connection with our delivery of other financial services to them or their customers which are subject to the regulatory classification of “brokered deposits” even though we consider these to be relationship deposits and they are not subject to the typical risks or market pricing associated with conventional brokered deposits.

If we do not maintain our regulatory capital above the level required to be well capitalized we would be required to obtain FDIC consent for us to continue to accept deposits classified as brokered deposits and there can be no assurance that the FDIC would consent under any circumstances. We could be required to suspend or eliminate deposit gathering from any source classified as “brokered” deposits. The FDIC can change the definition of or extend the classification to deposits not currently classified as brokered deposits. These non-traditional deposits are subject to greater operational and reputational risk of unexpected withdrawal than traditional demand and time deposits, particularly those provided by consumers. A significant decrease in our balances of brokered deposits could have a material adverse effect upon our financial condition and results of operations. See Management’s Discussion and Analysis of Financial Condition and Results of Operations below for further discussion of our liquidity.

We must continue to attract, retain and develop key personnel. Our success depends to a significant extent upon our ability to attract and retain experienced bankers in each of our markets as well as managers with the operational skills to build and maintain the infrastructure and controls required to support continuing loan growth. Competition for the best people in our industry can be intense, and there is no assurance that we will continue to have the same level of success in this effort that has supported our historical results. Factors that affect our ability to attract and retain key employees include our compensation and benefits programs, our profitability, our reputation for rewarding and promoting qualified employees and market competition for employees with certain skills, including information systems development and security. The cost of employee compensation is a significant portion of our operating expenses and can materially impact our results of operations. The unanticipated loss of the services of key personnel could have an adverse effect on our business. Although we have entered into employment agreements with certain key employees, we cannot assure you that we will be successful in retaining them.

15

We must effectively manage our information systems risk. We rely heavily on our communications and information systems to conduct our business. The financial services industry is undergoing rapid technological changes with frequent introductions of new technology-driven products and services. Our ability to compete successfully depends in part upon our ability to use technology to provide products and services that will satisfy customer demands. Many ofour competitors invest substantially greater resources in technological capabilities than we do. We may not be able to effectively implement new technology-driven products and services or be successful in marketing these products and services to our customers, which may negatively affect our business, results of operations or financial condition.

Our communications and information systems remain vulnerable to unexpected disruptions, failures and cyber attacks. The frequency and intensity of such attacks in our industry is escalating. Any failure or interruption of these systems could impair our ability to serve our customers and to operate our business and could damage our reputation, result in a loss of business, subject us to additional regulatory scrutiny or enforcement or expose us to civil litigation and possible financial liability. While we have developed extensive recovery plans, we cannot assure that those plans will be effective to prevent adverse effects upon us and our customers resulting from system failures.

We collect and store sensitive data, including personally identifiable information of our customers and employees. Computer break-ins of our systems or our customers’ systems, thefts of data and other breaches and criminal activity may result in significant costs to respond, liability for customer losses if we are at fault, damage to our customer relationships, regulatory scrutiny and enforcement and loss of future business opportunities due to reputational damage. Although we, with the help of third-party service providers, will continue to implement security technology and establish operational procedures to protect sensitive data, there can be no assurance that these measures will be effective. We advise and provide training to our customers regarding protection of their systems, but there is no assurance that our advice and training will be appropriately acted upon by our customers or effective to prevent losses. In some cases we may elect to contribute to the cost of responding to cybercrime against our customers, even when we are not at fault, in order to maintain valuable customer relationships. Successful cyber-attacks on our Bank or customers may affect the reputation of our bank, and failure to meet customer expectations could have a material impact on our ability to attract and retain deposits as a primary source of funding.

Our operations rely on external vendors. We rely on certain external vendors to provide products and services necessary to maintain our day-to-day operations, particularly in the areas of operations, treasury management systems, information technology and security, exposing us to the risk that these vendors will not perform as required by our agreements. An external vendor’s failure to perform in accordance with our agreement could be disruptive to our operations, which could have a material adverse impact on our business, financial condition and results of operations, as well as cause reputation damage if our customers are affected by the failure. External vendors who must have access to our information systems in order to provide their services have been identified as significant sources of information technology security risk. While we have implemented an active program of oversight to address this risk, there can be no assurance that we will not experience material security breaches associated with our vendors.

Our business faces unpredictable economic and business conditions. Our business is directly impacted by general economic and business conditions in Texas, the United States and abroad. The credit quality of our loan portfolio necessarily reflects, among other things, the general economic conditions in the areas in which we conduct our business. Our continued financial success can be affected by other factors that are beyond our control, including:

• national, regional and local economic conditions;

• general economic consequences of international conditions, such as weakness in European sovereign debt and foreign currencies and the impact of that weakness on the US and global economies;

• legislative and regulatory changes impacting our industry;

• the financial health of our customers and economic conditions affecting them and the value of our collateral, including changes in the price of energy and other commodities;

• the incidence of fraud, illegal payments, security breaches and other illegal acts among or impacting our bank and our customers;

• structural changes in the markets for origination, sale and servicing of residential mortgages;

• changes in governmental economic and regulatory policies generally, including the extent and timing of intervention in credit markets by the Federal Reserve Board or withdrawal from that intervention;

• changes in the availability of liquidity at a systemic level; and

• material inflation or deflation.

Substantial deterioration in any of the foregoing conditions can have a material adverse effect on our prospects and our results of operations and financial condition. There is no assurance that we will be able to sustain our historical rate of growth or our profitability. Our bank's customer base is primarily commercial in nature, and our bank does not have a significant retail branch network or retail consumer deposit base. In periods of economic downturn, business and commercial deposits may be more

16

volatile than traditional retail consumer deposits. As a result, our financial condition and results of operations could be adversely affected to a greater degree by these uncertainties than our competitors who have a larger retail customer base.

We compete with many banks and other financial service providers. Competition among providers of financial services in our markets, in Texas, regionally and nationally, is intense. We compete with other financial and bank holding companies, state and national commercial banks, savings and loan associations, consumer finance companies, credit unions, securities brokerages, insurance companies, mortgage banking companies, money market mutual funds, asset-based non-bank lenders, government sponsored or subsidized lenders and other financial services providers. Many of these competitors have substantially greater financial resources, lending limits and technological resources and larger branch networks than we do, and are able to offer a broader range of products and services than we can, including systems and services that could protect customers from cyber threats. Many competitors offer lower interest rates and more liberal loan terms that appeal to borrowers but adversely affect net interest margin and assurance of repayment. We are increasingly faced with competition in many of our products and services by non-bank providers who may have competitive advantages of size, access to potential customers and fewer regulatory requirements. Failure to compete effectively for deposit, loan and other banking customers in our markets could cause us to lose market share, slow or reverse our growth rate or suffer adverse effects on our financial condition and results of operations.

Our accounting estimates and risk management processes rely on management judgment, which may be supported by analytical and forecasting models. The processes we use to estimate probable credit losses for purposes of establishing the allowance for loan losses and to measure the fair value of financial instruments, as well as the processes we use to estimate the effects of changing interest rates and other market measures on our financial condition and results of operations, depend upon management’s judgment. Management’s judgment and the data relied upon by management may be based on assumptions that prove to be inaccurate, particularly in times of market stress or other unforeseen circumstances. Even if the relevant factual assumptions are accurate, our decisions may prove to be inadequate or inaccurate because of other flaws in the design or use of analytical tools used by management. Any such failures in our processes for producing accounting estimates and managing risks could have a material adverse effect on our business, financial condition and results of operations.

Our controls and procedures may fail or be circumvented. Management regularly reviews and updates our internal controls over financial reporting, disclosure controls and procedures, and corporate governance policies and procedures. Any system of controls, however well designed and operated, is based in part on certain assumptions and can provide only reasonable, not absolute, assurances that the objectives of the system are met. Any failure or circumvention of our controls and procedures or failure to comply with regulations related to controls and procedures could have a material adverse effect on our business, results of operations and financial condition.

We must effectively manage our counterparty risk. Financial services institutions are interrelated as a result of trading, clearing, counterparty and other relationships. Our bank has exposure to many different industries and counterparties, and routinely executes transactions with counterparties in the financial services industry, including commercial banks, brokers and dealers, investment banks, and other institutional clients. Many of these transactions expose our bank to credit risk in the event of a default by a counterparty or client. In addition, our bank’s credit risk may be increased when the collateral it is entitled to cannot be realized upon or is liquidated at prices not sufficient to recover the full amount of its credit or derivative exposure. Any such losses could have a material adverse effect on our business, financial condition and results of operations.

Our business is susceptible to fraud. Our business exposes us to fraud risk from our loan and deposit customers, the parties they do business with, as well as from our employees, contractors and vendors. We rely on financial and other data from new and existing customers which could turn out to be fraudulent when accepting such customers, executing their financial transactions and making and purchasing loans and other financial assets. In times of increased economic stress we are at increased risk of fraud losses. We believe we have underwriting and operational controls in place to prevent or detect such fraud, but we cannot provide assurance that these controls will be effective in detecting fraud or that we will not experience fraud losses or incur costs or other damage related to such fraud, at levels that adversely affect our financial results or reputation. Our lending customers may also experience fraud in their businesses which could adversely affect their ability to repay their loans.

We are subject to extensive government regulation and supervision. We, as a bank holding company and financial holding company, and our bank as a national bank, are subject to extensive federal and state regulation and supervision that impacts our business on a daily basis. See the discussion above at Business - Regulation and Supervision. These regulations affect our lending practices, permissible products and services and their terms and conditions, customer relationships, capital structure, investment practices, accounting, financial reporting, operations and our ability to grow, among other things. These regulations also impose obligations to maintain appropriate policies, procedures and controls to detect, prevent and report money laundering and terrorist financing and to verify the identities of our customers.

Congress and federal regulatory agencies continually review banking laws, regulations and policies for possible changes. Changes to statutes, regulations or regulatory policies, including changes in interpretation or implementation of statutes, regulations or policies, could affect us in substantial and unpredictable ways. Recent material changes in regulation and requirements imposed on financial institutions, such as the Dodd-Frank Act and the Basel III Accord, result in additional costs,

17

impose more stringent capital, liquidity and leverage requirements, limit the types of financial services and products we may offer and increase the ability of non-bank financial services providers to offer competing financial services and products, among other things. The Dodd-Frank Act has not yet been fully implemented and there are many additional regulations that have not been proposed, or if proposed, have not been adopted. The full impact of the Dodd-Frank Act on our business strategies is unknown at this time and cannot be predicted.

We receive inquiries from our regulators from time to time regarding, among other things, lending practices, reserve methodology, compliance with ever-changing regulations and interpretations, interest rate, liquidity and operational risk management, regulatory and financial accounting practices and policies and related matters, which can divert management’s time and attention from focusing on our business. We became subject to additional regulatory requirements commencing in 2013 as a result of our assets exceeding $10 billion and have increased the amount of management time and expense devoted to developing the infrastructure to support our expanding compliance obligations. We are actively engaged in responding to stress testing requirements contained in the Dodd-Frank Act to evaluate the adequacy of our capital and liquidity planning. Uncertainties regarding how the financial models of our business created pursuant to this requirement will respond to the regulatory scenarios issued in late 2014, and how our regulators will evaluate our report of the results obtained, subject us to increased regulatory risk in 2015 and future years as this new activity is implemented. Any change to our practices or policies requested or required by our regulators, or any changes in interpretation of regulatory policy applicable to our businesses, may have a material adverse effect on our business, results of operations or financial condition. We increased our capital and liquidity and expanded our regulatory compliance staffing and systems during 2014 in order to assure that we continue to satisfy regulatory expectations for high-growth institutions, which reduced our net interest margin and earnings in 2014.  There is no assurance that our financial performance in 2015 and future years will not be similarly burdened.

We expend substantial effort and incur costs to continually improve our systems, controls, accounting, operations, information security, compliance, audit effectiveness, analytical capabilities, staffing and training in order to satisfy regulatory requirements. We cannot offer assurance that these efforts will be accepted by our regulators as satisfying the legal and regulatory requirements applicable to us. Failure to comply with relevant laws, regulations or policies could result in sanctions by regulatory agencies, civil money penalties and/or reputation damage, which could have a material adverse effect on our business, financial condition and results of operations. While we have policies and procedures designed to prevent any such violations, there can be no assurance that such violations will not occur.

The FDIC has imposed higher general and special assessments on deposits or assets based on general industry conditions and as a result of changes in specific programs, as well as qualitative adjustments for individual institutions based on their risk characteristics which cannot be predicted with any certainty. There is no restriction on the amount by which the FDIC may increase deposit and asset assessments in the future. Increases in FDIC assessments, fees and taxes have adversely affected our earnings in 2014 and may continue to do so in the future.

Reports from the Public Company Accounting Oversight Board’s (“PCAOB”) inspections of public accounting firms continue to outline findings and recommendations which could require these firms to perform additional work as part of their financial statement audits, increasing our audit and internal audit costs to respond to these added requirements and exposure to adverse findings by the PCAOB of the work performed. As a result, we have experienced, and may continue to experience, greater internal and external compliance and audit costs to comply with these changes that could adversely affect our results of operations.

We must maintain adequate regulatory capital to support our business objectives. Under regulatory capital adequacy guidelines and other regulatory requirements, we must satisfy capital requirements based upon quantitative measures of assets, liabilities and certain off-balance sheet items. Our satisfaction of these requirements is subject to qualitative judgments by regulators that may differ materially from management’s and that are subject to being determined retroactively for prior periods. Our ability to maintain our status as a financial holding company and to continue to operate our bank as we have in recent periods is dependent upon a number of factors, including our bank qualifying as “well capitalized” and “well managed” under applicable prompt corrective action regulations and upon our company qualifying on an ongoing basis as “well capitalized” and “well managed” under applicable Federal Reserve regulations.

Failure to meet regulatory capital standards could have a material adverse effect on our business, including damaging the confidence of customers in us, adversely impacting our reputation with respect to competitive position and retention of key people, limiting our ability to use brokered deposits, limiting our access to the Federal Reserve discount window and advances from the Federal Home Loan Bank, limiting our access to capital markets transactions, limiting our ability to pursue new activities and resulting in higher FDIC assessments on deposits or assets. If we fall below guidelines for being deemed “adequately capitalized” the OCC or Federal Reserve could impose further restrictions and requirements in order to effect “prompt corrective action.” The capital requirements applicable to us are in a process of continuous evaluation and revision in connection with Basel III and the requirements of the Dodd-Frank Act. We cannot predict the final form, or the effects, of these regulations on our business, but among the possible effects are requirements that we slow our rate of growth or obtain additional capital which could reduce our earnings or dilute our existing stockholders.

18

We are dependent on funds obtained from capital transactions or from our bank to fund our obligations. We are a financial holding company engaged in the business of managing, controlling and operating our bank. We conduct no material business or other activity at the parent company level other than activities incidental to holding equity and debt investments in our bank. As a result, we rely on the proceeds of capital transactions, payments of interest and principal on loans made to our bank and dividends on preferred stock issued by our bank to pay our operating expenses, to satisfy our obligations to debtholders and to pay dividends on our preferred stock. Our bank’s ability to pay dividends may be limited. The profitability of our bank is subject to fluctuation based upon, among other things, the cost and availability of funds, changes in interest rates and economic conditions in general. Our bank’s ability to pay dividends to us is subject to regulatory limitations that can, under certain adverse circumstances, prohibit the payment of dividends to us. Our right to participate in any distribution from the sale or liquidation of our bank is subject to the prior claims of our bank’s creditors.

If we are unable to access funds from capital transactions, or dividends or interest on loan payments from our bank, we may be unable to satisfy our obligations to creditors or debtholders or pay dividends on our preferred stock. Changes in our bank’s operating results or capital requirements could require us to convert subordinated notes or preferred stock of our bank held by us into common equity, reducing our cash flow available to meet obligations.

We are subject to environmental liability risk associated with lending activities. A significant portion of our loan portfolio is secured by real property. During the ordinary course of business, we may foreclose on and take title to properties securing certain loans. There is a risk that hazardous or toxic substances could be found on these properties, and that we may be liable for remediation costs, as well as for personal injury and property damage. Environmental laws may require us to incur substantial expenses and may materially reduce the affected property's value by limiting our ability to use or sell it. Although we have policies and procedures requiring environmental review before initiating any foreclosure action on real property, these reviews may not be sufficient to detect all potential environmental hazards. The remediation costs and any other financial liabilities associated with an environmental hazard could have a material adverse effect on our financial condition and results of operations. Future laws or regulations or more stringent interpretations or enforcement policies with respect to existing laws and regulations may increase our exposure to environmental liability.

Severe weather, earthquakes, other natural disasters, pandemics, acts of war or terrorism and other external events could significantly impact our business. Severe weather, earthquakes, other natural disasters, pandemics, acts of war or terrorism and other adverse external events could have a significant impact on our ability to conduct business. Such events could affect the stability of our deposit base, impair the ability of borrowers to repay outstanding loans, impair the value of collateral securing loans, cause significant property damage, result in loss of revenue and/or cause us to incur additional expenses. Hurricanes have caused extensive flooding and destruction along the coastal areas of Texas, including communities where we conduct business. Although management has established disaster recovery policies and procedures, the occurrence of any such events could have a material adverse effect on our business, financial condition and results of operations.

We are subject to claims and litigation in the ordinary course of our business, including claims that may not be covered by our insurers. Customers and other parties we engage with assert claims and take legal action against us on a regular basis and we regularly take legal action to collect unpaid borrower obligations, realize on collateral and assert our rights in commercial and other contexts. These actions frequently result in counter-claims against us. Litigation arises in a variety of contexts, including lending activities, employment practices, commercial agreements, fiduciary responsibility related to our wealth management services, intellectual property rights and other general business matters.

Claims and legal actions may result in significant legal costs to defend us or assert our rights and reputational damage that adversely affects existing and future customer relationships. If claims and legal actions are not resolved in a manner favorable to us we may suffer significant financial liability or adverse effects upon our reputation, which could have a material adverse effect on our business, financial condition and results of operations. See Legal Proceedings below for additional disclosures regarding legal proceedings.

We purchase insurance coverage to mitigate a wide range of operating risks, including general liability, errors and omissions, professional liability, business interruption, cyber-crime and property loss, for events that may be materially detrimental to our bank or customers. There is no assurance that our insurance will be adequate to protect us against material losses in excess of our coverage limits or that insurers will perform their obligations under our policies without attempting to limit or exclude coverage. We could be required to pursue legal actions against insurers to obtain payment of amounts we are owed, and there is no assurance that such actions, if pursued, would be successful.

Risks Relating to Our Securities

Our stock price can be volatile. Stock price volatility may 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 variations in quarterly and annual results of operations;

• changes in recommendations by securities analysts;

19

• changes in composition and perceptions of the investors who own our stock and other securities;

• changes in ratings from national rating agencies on publicly or privately owned debt securities;

• operating and stock price performance of other companies that investors deem comparable to us;

• news reports relating to trends, concerns and other issues in the financial services industry, including regulatory actions against other financial institutions;

• actual or expected economic conditions that are perceived to affect our company such as changes in commodity prices, real estate values or interest rates;

• perceptions in the marketplace regarding us and/or our competitors;

• new technology used, or services offered, by competitors;

• significant acquisitions or business combinations, strategic partnerships, joint ventures or capital commitments by or involving us or our competitors;

• changes in government regulations and interpretation of those regulations, changes in our practices requested or required by regulators and changes in regulatory enforcement focus; and

• geopolitical conditions such as acts or threats of terrorism or military conflicts.

General market fluctuations, industry factors and general economic and political conditions and events, such as economic slowdowns or recessions, interest rate changes or credit loss trends, could also cause our stock price to decrease regardless of operating results as evidenced by the recent volatility and disruption of capital and credit markets.

The trading volume in our common stock is less than that of other larger financial services companies. Although our common stock is traded on the Nasdaq Global Select Market, the trading volume in our common stock is less than that of other larger financial services companies. Given the lower trading volume of our common stock, significant sales of our common stock, or the expectation of these sales, could cause our stock price to fall. In addition, a substantial majority of common stock outstanding is held by institutional shareholders, and trading activity involving large positions may increase volatility of the stock price. Concentration of ownership by institutional investors and inability to execute trades covering large numbers of shares can increase volatility of stock price. Changes in general economic outlook or perspectives on our business or prospects by our institutional investors, whether factual or speculative, can have a major impact on our stock price.

Our preferred stock is thinly traded. There is only a limited trading volume in our preferred stock due to the small size of the issue and its largely institutional holder base. Significant sales of our preferred stock, or the expectation of these sales, could cause the price of the preferred stock to fall substantially.

An investment in our securities is not an insured deposit. Our common stock, preferred stock and indebtedness are not bank deposits and, therefore, are not insured against loss by the FDIC, any other deposit insurance fund or by any other public or private entity. Investment in our common stock is inherently risky for the reasons described in this “Risk Factors” section and elsewhere in this report and is subject to the same market forces that affect the price of securities of any company. As a result, if you acquire our common stock, preferred stock or indebtedness, you may lose some or all of your investment.

The holders of our indebtedness and preferred stock have rights that are senior to those of our common shareholders. As of December 31, 2014, we had $111.0 million in subordinated notes and $113.4 million in junior subordinated notes outstanding that are held by statutory trusts which issued trust preferred securities to investors. At December 31, 2014 our bank had $175.0 million in subordinated notes outstanding. Payments of the principal and interest on our trust preferred securities are conditionally guaranteed by us to the extent not paid by each trust, provided the trust has funds available for such obligations.

Our subordinated notes and junior subordinated notes are senior to our shares of preferred stock and common stock in right of payment of dividends and other distributions. We must be current on interest and principal payments on our indebtedness before any dividends can be paid on our preferred stock or our common stock. In the event of our bankruptcy, dissolution or liquidation, the holders of our indebtedness must be satisfied before any distributions can be made to our preferred or common shareholders. If certain conditions are met, we have the right to defer interest payments on the junior subordinated debentures (and the related trust preferred securities) at any time or from time to time for a period not to exceed 20 consecutive quarters in a deferral period, during which time no dividends may be paid to holders of our preferred stock or common stock. Because our bank’s subordinated notes are obligations of the bank, they would in any sale or liquidation of our bank receive payment before any amounts would be payable to holders of our common stock, preferred stock or subordinated notes.

At December 31, 2014, we had issued and outstanding 6 million shares of our 6.50% Non-Cumulative Perpetual Preferred Stock, Series, A, having an aggregate liquidation preference of $150.0 million. Our preferred stock is senior to our shares of common stock in right of payment of dividends and other distributions. We must be current on dividends payable to holders of preferred stock before any dividends can be paid on our common stock. In the event of our bankruptcy, dissolution or liquidation, the holders of our preferred stock must be satisfied before any distributions can be made to our common shareholders.

20

We do not currently pay dividends on our common stock. We have not paid dividends on our common stock and we do not expect to do so for the foreseeable future. Our ability to pay dividends is limited by regulatory restrictions and the need to maintain sufficient consolidated capital. The ability of our bank to pay dividends to us is limited by its obligation to maintain sufficient capital and by other regulatory restrictions as discussed above at We are dependent on funds obtained from capital transactions or from our bank to fund our obligations.

Restrictions on Ownership. The ability of a third party to acquire us is limited under applicable U.S. banking laws and regulations. The Bank Holding Company Act of 1956, as amended (the “BHCA”), requires any bank holding company (as defined therein) to obtain the approval of the Board of Governors of the Federal Reserve System (“Federal Reserve”) prior to acquiring, directly or indirectly, more than 5% of our outstanding Common Stock. Any “company” (as defined in the BHCA) other than a bank holding company would be required to obtain Federal Reserve approval before acquiring “control” of us. “Control” generally means (i) the ownership or control of 25% or more of a class of voting securities, (ii) the ability to elect a majority of the directors or (iii) the ability otherwise to exercise a controlling influence over management and policies. A holder of 25% or more of our outstanding Common Stock, other than an individual, is subject to regulation and supervision as a bank holding company under the BHCA. In addition, under the Change in Bank Control Act of 1978, as amended, and the Federal Reserve’s regulations thereunder, any person, either individually or acting through or in concert with one or more persons, is required to provide notice to the Federal Reserve prior to acquiring, directly or indirectly, 10% or more of our outstanding common stock.

Anti-takeover provisions of our certificate of incorporation, bylaws and Delaware law may make it more difficult for you to receive a change in control premium. Certain provisions of our certificate of incorporation and bylaws could make a merger, tender offer or proxy contest more difficult, even if such events were perceived by many of our stockholders as beneficial to their interests. These provisions include advance notice for nominations of directors and stockholders' proposals, and authority to issue “blank check” preferred stock with such designations, rights and preferences as may be determined from time to time by our board of directors. In addition, as a Delaware corporation, we are subject to Section 203 of the Delaware General Corporation Law which, in general, prevents an interested stockholder, defined generally as a person owning 15% or more of a corporation's outstanding voting stock, from engaging in a business combination with our company for three years following the date that person became an interested stockholder unless certain specified conditions are satisfied.

Limitations on payment of subordinated notes. Under the Federal Deposit Insurance Act (“FDIA”), “critically undercapitalized” banks may not, beginning 60 days after becoming critically undercapitalized, make any payment of principal or interest on their subordinated debt (subject to certain limited exceptions). In addition, under Section 18(i) of the FDIA, our bank is required to obtain the advance consent of the FDIC to retire any part of its subordinated notes. Under the FDIA, a bank may not pay interest on its subordinated notes if such interest is required to be paid only out of net profits, or distribute any of its capital assets, while it remains in default on any assessment due to the FDIC.

Our bank’s subordinated indebtedness is unsecured and subordinate and junior in right of payment to the bank’s obligations to its depositors, its obligations under banker’s acceptances and letters of credit, its obligations to any Federal Reserve Bank, certain obligations to the FDIC, and its obligations to its other creditors, whether now outstanding or hereafter incurred, except any obligations which expressly rank on a parity with or junior to the notes, including subordinated notes payable to the Company.

ITEM 6. SELECTED CONSOLIDATED FINANCIAL DATA

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Forward-Looking Statements

Statements and financial analysis contained in this report that are not historical facts are forward-looking statements made pursuant to the safe harbor provisions of federal securities laws. Forward-looking statements may also be contained in our future filings with SEC, in press releases and in oral and written statements made by us or with our approval that are not statements of historical fact. Forward-looking statements describe our future plans, strategies and expectations and are based on certain assumptions. Words such as “believes”, “expects,” “estimates,” “anticipates”, “plans”, “goals”, “objectives”, “expects”, “intends”, “seeks”, “likely”, “targeted”, “continue”, “remain”, “will”, “should”, “may” and other similar expressions are intended to identify forward-looking statements but are not the exclusive means of identifying such statements. Forward-looking statements may include, among other things, statements about our confidence in our strategies and our expectations about financial performance, market growth, market and regulatory trends and developments, acquisitions and divestitures, new technologies, services and opportunities and earnings.

Forward-looking statements are subject to various risks and uncertainties, which change over time, are based on management’s expectations and assumptions at the time the statements are made and are not guarantees of future results. Important factors that could cause actual results to differ materially from the forward-looking statements include, but are not limited to, the following:

• Deterioration of the credit quality of our loan portfolio, increased default rates and loan losses or adverse changes in the industry concentrations of our loan portfolio.

• Developments adversely affecting our commercial, entrepreneurial and professional customers.

• Changes in the U.S. economy in general or the Texas economy specifically resulting in deterioration of credit quality or reduced demand for credit or other financial services we offer, including declines and volatility in oil and gas prices.

• Changes in the value of commercial and residential real estate securing our loans or in the demand for credit to support the purchase and ownership of such assets.

• The failure of assumptions supporting our allowance for loan losses causing it to become inadequate as loan quality decreases and losses and charge-offs increase.

• A failure to effectively manage our interest rate risk resulting from unexpectedly large or sudden changes in interest rates or rate or maturity imbalances in our assets and liabilities.

• Failure to execute our business strategy, including any inability to expand into new markets and lines of business in Texas, regionally and nationally.

• Loss of access to capital market transactions and other sources of funding, or a failure to effectively balance our funding sources with cash demands by depositors and borrowers.

• Failure to successfully develop and launch new lines of business and new products and services within the expected time frames and budgets, or failure to anticipate and appropriately manage the associated risks.

• The failure to attract and retain key personnel or the loss of key individuals or groups of employees.

• Legislative and regulatory changes imposing further restrictions and costs on our business, a failure to remain well capitalized or well managed or regulatory enforcement actions against us.

• An increase in the incidence or severity of fraud, illegal payments, security breaches and other illegal acts impacting our bank and our customers.

• Structural changes in the markets for origination, sale and servicing of residential mortgages.

• Increased or more effective competition from banks and other financial service providers in our markets.

• Material failures of our accounting estimates and risk management processes based on management judgment, or the supporting analytical and forecasting models.

• Unavailability of funds obtained from capital transactions or from our bank to fund our obligations.

• Failures of counterparties or third party vendors to perform their obligations.

• Failures or breaches of our information systems that are not effectively managed.

• Severe weather, natural disasters, acts of war or terrorism and other external events.

• Incurrence of material costs and liabilities associated with legal and regulatory proceedings and related matters with respect to the financial services industry, including those directly involving us or our bank.

• Failure of our risk management strategies and procedures, including failure or circumvention of our controls.

27

Actual outcomes and results may differ materially from what is expressed in our forward-looking statements and from our historical financial results due to the factors discussed elsewhere in this report or disclosed in our other SEC filings. Forward-looking statements included herein should not be relied upon as representing our expectations or beliefs as of any date subsequent to the date of this report. Except as required by law, we undertake no obligation to revise any forward-looking statements contained in this report, whether as a result of new information, future events or otherwise. The factors discussed herein are not intended to be a complete summary of all risks and uncertainties that may affect our businesses. Though we strive to monitor and mitigate risk, we cannot anticipate all potential economic, operational and financial developments that may adversely impact our operations and our financial results. Forward-looking statements should not be viewed as predictions and should not be the primary basis upon which investors evaluate an investment in our securities.

Overview of Our Business Operations

We commenced our banking operations in December 1998. An important aspect of our growth strategy has been our ability to service and manage effectively a large number of loans and deposit accounts in multiple markets in Texas, as well as several lines of business serving a regional or national clientele of commercial borrowers. Accordingly, we have created an operations infrastructure sufficient to support our lending and banking operations that we continue to build out as needed to serve a larger customer base and specialized industries.

The following discussion and analysis presents the significant factors affecting our financial condition as of December 31, 2014 and 2013 and results of operations for each of the three years related to the periods ended December 31, 2014, 2013 and 2012. This discussion should be read in conjunction with our consolidated financial statements and notes to the financial statements appearing later in this report.

Year ended December 31, 2014 compared to year ended December 31, 2013

We reported net income of $136.4 million and net income available to common stockholders of $126.6 million, or $2.88 per diluted common share, for the year ended December 31, 2014, compared to net income of $121.1 million and net income available to common stockholders of $113.7 million, or $2.72 per diluted common share, for the same period in 2013. Return on average equity ("ROE") was 11.31% and return on average assets ("ROA") was 1.05% for the year ended December 31, 2014, compared to 12.82% and 1.17%, respectively, for the same period in 2013. During 2014, we completed a $175.0 million subordinated debt offering and two equity offerings totaling 4.4 million common shares, which increased common equity by $256.2 million. These transactions had the effect of reducing ROE during 2014. The ROA decrease resulted from the subordinated debt offering and from a combination of reduced yields on loans and an increase in average liquidity assets for the year ended December 31, 2014 compared to the same period of 2013.

Net income increased $15.3 million for the year ended December 31, 2014 compared to 2013. The $15.3 million increase was primarily the result of a $57.5 million increase in net interest income, offset by a $3.0 million increase in the provision for credit losses, a $1.5 million decrease in non-interest income, a $28.4 million increase in non-interest expense and a $9.3 million increase in income tax expense.

Details of the changes in the various components of net income are further discussed below.

Year ended December 31, 2013 compared to year ended December 31, 2012

We reported net income of $121.0 million and net income available to common stockholders of $113.7 million, or $2.72 per diluted common share, for the year ended December 31, 2013, compared to net income and net income available to common stockholders of $120.7 million, or $3.01 per diluted common share, for the same period in 2012. Return on average equity was 12.82% and return on average assets was 1.17% for the year ended December 31, 2013, compared to 16.93% and 1.35%, respectively, for the same period in 2012.

Net income increased $337,000 for the year ended December 31, 2013 compared to 2012. The $337,000 increase was primarily the result of a $42.6 million increase in net interest income, a $984,000 increase in non-interest income and a $1.1 million decrease in income tax expense, offset by a $7.5 million increase in the provision for credit losses and a $36.9 million increase in non-interest expense.

Details of the changes in the various components of net income are further discussed below.

Net Interest Income

Net interest income was $477.0 million for the year ended December 31, 2014 compared to $419.5 million for the same period of 2013. The increase in net interest income was primarily due to an increase of $2.7 billion in average earning assets as compared to the same period of 2013. The increase in average earning assets from 2013 included a $2.4 billion increase in average net loans and a $300.6 million increase in liquidity assets, offset by a $28.0 million decrease in average securities. For the year ended December 31, 2014, average net loans, liquidity assets and securities represented 96%, 4% and less than 1%, respectively, of average earning assets compared to 98%, 1% and 1%, respectively, in 2013.

28

Average interest-bearing liabilities for the year ended December 31, 2014 increased $1.2 billion from the year ended December 31, 2013, which included a $1.3 billion increase in interest-bearing deposits and a $160.6 million increase in long-term debt as a result of the Bank's issuance of subordinated notes in January 2014, offset by a $273.4 million decrease in other borrowings. For the same periods, the average balance of demand deposits increased to $4.2 billion from $3.0 billion. The average cost of total deposits and borrowed funds remained flat at 0.17% for the year ended December 31, 2014, compared to the same period in the prior year. The total cost of interest-bearing liabilities included $8.7 million attributable to the $175.0 million in long-term subordinated debt issued in January 2014. Including the increase in long-term subordinated debt during 2014, the average cost of interest-bearing liabilities increased from 0.40% for the year ended December 31, 2013 to 0.50% for the same period of 2014.

Net interest income was $419.5 million for the year ended December 31, 2013 compared to $376.9 million for the same period of 2012. The increase in net interest income was primarily due to an increase of $1.4 billion in average earning assets as compared to the same period of 2012. The increase in average earning assets from 2012 included a $1.4 billion increase in average net loans offset by a $40.2 million decrease in average securities. For the year ended December 31, 2013, average net loans, liquidity assets and securities represented 98%, 1% and 1%, respectively, of average earning assets compared to 98%, 1% and 1%, respectively, in 2012.

Average interest-bearing liabilities for the year ended December 31, 2013 increased $95.6 million from the year ended December 31, 2012, which included a $947.9 million increase in interest-bearing deposits, a $932.4 million decrease in other borrowings and an $80.1 million increase in subordinated notes. For the same periods, the average balance of demand deposits increased to $3.0 billion from $2.0 billion. The average cost of interest-bearing liabilities increased from 0.35% for the year ended December 31, 2012 to 0.40% in 2013 related to the subordinated notes issued in the third quarter of 2012.

Volume/Rate Analysis

The following table presents the changes (in thousands) in taxable-equivalent net interest income and identifies the changes due to differences in the average volume of earning assets and interest-bearing liabilities and the changes due to changes in the average interest rate on those assets and liabilities.

(1) Changes attributable to both volume and yield/rate are allocated to both volume and yield/rate on an equal basis.

(2) Taxable equivalent rates used where applicable assuming a 35% tax rate.

Net interest margin, which is defined as the ratio of net interest income to average earning assets, decreased from 4.22% for 2013 to 3.78% in 2014. This 44 basis point decrease was due to the growth in loans with lower yields, the impact of the January 2014 subordinated note offering and the $300.6 million increase in average balances of liquidity assets, which includes Federal funds sold and deposits in other banks. Funding costs, including demand deposits and borrowed funds, remained at .17% for 2014 compared to .17% for 2013. The spread on total earning assets, net of the cost of deposits and borrowed funds, was 3.91%

29

for 2014 compared to 4.30% for 2013. The decrease resulted from the reduction in yields on total loans, primarily due to the increased proportion of mortgage finance loans to total loans. Total funding costs, including all deposits, long-term debt and stockholders' equity increased to .29% for 2014 compared to .24% for 2013. Average long-term debt increased by $160.6 million from 2013 and the average interest rate on long-term debt for 2014 was 4.85% compared to 4.40% for 2013.

Net interest margin decreased from 4.41% for 2012 to 4.22% for 2013. This 19 basis point decrease was a result of a decrease in interest income as a percent of earning assets offset by a reduction in funding costs. Total cost of funding remained consistent at .24% for 2012 and 2013. Funding costs, including demand deposits and borrowed funds, decreased from .21% for 2012 to .17% for 2013. The cost of subordinated debt issued in September 2012 and the trust preferred as a percent of total earning assets was .10% for 2013 compared to .06% for 2012.

Total non-interest income	$	42,511	$	44,024	$	43,040

Non-interest income decreased by $1.5 million during the year ended December 31, 2014 to $42.5 million, compared to $44.0 million during the same period in 2013. This decrease was primarily due to a $3.0 million decrease in brokered loan fees as a result of lower per loan fees in our mortgage finance business. Swap fee income decreased $2.5 million during 2014 compared to the same period of 2013. These fees fluctuate from time to time based on the number and volume of transactions closed during the quarter. Swap fees are fees related to customer swap transactions and are received from the institution that is our counterparty on the transaction. Offsetting these decreases was a $3.5 million increase in other non-interest income. Other non-interest income includes such items as letter of credit fees and other general operating income, none of which account for 1% or more of total interest income and non-interest income.

Non-interest income increased by $1.0 million during the year ended December 31, 2013 to $44.0 million, compared to $43.0 million during the same period in 2012. The increase was primarily due to an $861,000 increase in other non-interest income.

While management expects continued growth in certain components of non-interest income, the future rate of growth could be affected by increased competition from nationwide and regional financial institutions and general economic conditions. In order to achieve continued growth in non-interest income, we may need to introduce new products or enter into new lines of business or expand existing lines of business. Any new product introduction or new market entry could place additional demands on capital and managerial resources and introduce new risks to our business.

(1) Other expense includes such items as courier expenses, regulatory assessments other than FDIC insurance, due from bank charges and other general operating expenses, none of which account for 1% or more of total interest income and non-interest income.

Non-interest expense for the year ended December 31, 2014 increased $28.4 million compared to the same period of 2013 primarily related to increases in salaries and employee benefits, net occupancy expense, legal and professional expense, communications and data processing and FDIC insurance assessment, offset by a decrease in allowance and other carrying costs for OREO.

Salaries and employee benefits expense increased $11.3 million to $169.1 million during the year ended December 31, 2014. This increase resulted primarily from general business growth.

32

Net occupancy expense for the year ended December 31, 2014 increased $4.0 million as a result of general business growth and continued build-out needed to support our growth.

Legal and professional expense increased $3.1 million, or 17%, for the year ended December 31, 2014 compared to the same period in 2013. Our legal and professional expense will continue to fluctuate from year to year and could increase in the future with growth and as we respond to continued regulatory changes and strategic initiatives.

Communications and technology expense increased $4.9 million to $18.7 million during the year ended December 31, 2014 as a result of general business and customer growth and continued build-out needed to support that growth.

FDIC insurance assessment expense increased $2.8 million from $8.1 million in 2013 to $10.9 million primarily as a result of the difference in rates applied to banks with over $10 billion in assets.

For the year ended December 31, 2014, allowance and other carrying costs for OREO decreased $1.7 million to $85,000, which is consistent with the decrease in our OREO balances during 2014.

Non-interest expense for the year ended December 31, 2013 increased $36.9 million compared to the same period of 2012 primarily related to increases in salaries and employee benefits, marketing expense, communications and data processing and FDIC insurance assessment, offset by decreases in allowance and other carrying costs for OREO and litigation settlement expense.

Salaries and employee benefits expense increased $36.3 million to $157.8 million during the year ended December 31, 2013. Of the $36.3 million increase during 2013, approximately $7.7 million related to a charge taken to reflect the financial effect of the planned organizational change announced during the second quarter of 2013 related to the retirement and transition of our CEO and included assumptions about future payouts that may or may not occur. These payouts, when and if realized, will be directly linked to our performance and stock price, but were required to be estimated at the time of the event. Additionally, there was another $2.2 million of charges recorded in the second quarter of 2013 related to the increased probability that certain company financial performance targets for executive cash-based incentives would be met. Additionally, these cash-based and performance units were expensed based on current stock prices, which increased significantly during 2013 resulting in a $3.7 million increase in expense as compared to 2012. The remaining $22.7 million increase was primarily due to general business growth and build-out.

Marketing expense for the year ended December 31, 2013 increased $2.8 million compared to the same period in 2012. Marketing expense for the year ended December 31, 2013 included $1.0 million of direct marketing and advertising expense and $4.0 million in business development expense compared to $850,000 and $3.1 million, respectively, in 2012. Marketing expense for the year ended December 31, 2013 also included $11.2 million for the purchase of miles related to the American Airlines AAdvantage^® program and treasury management deposit programs compared to $9.5 million during 2012. Marketing expense may increase as we seek to further develop our brand, reach more of our target customers and expand in our target markets.

Legal and professional expense increased $547,000, or 3%, for the year ended December 31, 2013 compared to the same period in 2012.

Communications and technology expense increased $2.6 million to $13.8 million during the year ended December 31, 2013 as a result of general business and customer growth and continued build-out needed to support that growth.

FDIC insurance assessment expense increased $2.5 million from $5.6 million in 2012 to $8.1 million primarily as a result of a $3.0 million assessment by the FDIC that was paid during the third quarter of 2013. The assessment related to the year-end call reports for 2011 and 2012, which were amended for the change in the risk weight applicable to our mortgage finance loan portfolio as described in Note 13 – Regulatory Restrictions. As previously disclosed, the amendment caused one capital ratio to retroactively fall below “well-capitalized” for December 31, 2012 and 2011.

For the year ended December 31, 2013, allowance and other carrying costs for OREO decreased $7.3 million to $1.8 million, $920,000 of which related to deteriorating values of assets held in OREO. The decrease is consistent with the decrease in our OREO balances during 2013.

Analysis of Financial Condition

Loans

Our total loans have grown at an annual rate of 26%, 13% and 30% in 2014, 2013 and 2012, respectively, reflecting the continued build-up of our lending operations. Our business plan focuses primarily on lending to middle market businesses and successful professionals and entrepreneurs, and as such, commercial, real estate and construction loans have comprised a majority of our loan portfolio, representing 71% of total loans at December 31, 2014. Consumer loans generally have represented 1% or less of the portfolio from December 31, 2010 to December 31, 2014. Mortgage finance loans relate to our mortgage warehouse lending operations in which we invest in mortgage loan ownership interests that are typically sold within

33

10 to 20 days. Volumes fluctuate based on the level of market demand for the product and the number of days between purchase and sale of the loans, as well as overall market interest rates and tend to peak at the end of each month.

We originate a substantial majority of all loans held for investment (excluding mortgage finance loans). We also participate in syndicated loan relationships, both as a participant and as an agent. As of December 31, 2014, we had $1.6 billion in syndicated loans, $369.2 million of which we administer as agent. All syndicated loans, whether we act as agent or participant, are underwritten to the same standards as all other loans we originate. In addition, as of December 31, 2014, none of our syndicated loans were on non-accrual.

The following table summarizes our loans on a gross basis by major category as of the dates indicated (in thousands):

Commercial Loans and Leases.    Our commercial loan portfolio is comprised of lines of credit for working capital and term loans and leases to finance equipment and other business assets. Our energy production loans are generally collateralized with proven reserves based on appropriate valuation standards and take into account the risk of oil and gas price volatility. Our commercial loans and leases are underwritten after carefully evaluating and understanding the borrower’s ability to operate profitably. Our underwriting standards are designed to promote relationship banking rather than to make loans on a transaction basis. Our lines of credit typically are limited to a percentage of the value of the assets securing the line. Lines of credit and term loans typically are reviewed annually and are supported by accounts receivable, inventory, equipment and other assets of our clients’ businesses. At December 31, 2014, funded commercial loans and leases totaled approximately $6.0 billion, approximately 42% of our total funded loans.

Mortgage Finance Loans.    Our mortgage finance loans consist of ownership interests purchased in single-family residential mortgages funded through our warehouse lending group. These loans are typically on our balance sheet for 10 to 20 days or less. We have agreements with mortgage lenders and purchase interests in individual loans they originate. All loans are underwritten consistent with established programs for permanent financing with financially sound investors. Substantially all loans are conforming loans. At December 31, 2014, mortgage finance loans totaled approximately $4.1 billion, approximately 29% of our total funded loans. Mortgage finance loans as of December 31, 2014 were net of $358.3 million of participations sold.

Construction Loans.    Our construction loan portfolio consists primarily of single- and multi-family residential properties and commercial projects used in manufacturing, warehousing, service or retail businesses. Our construction loans generally have terms of one to three years. We typically make construction loans to developers, builders and contractors that have an established record of successful project completion and loan repayment and have a substantial equity investment in the borrowers. Loan amounts are derived primarily from the bank's evaluation of expected cash flows available to service debt from stabilized projects under hypothetically stressed conditions. Construction loans are also based in part upon estimates of costs and value associated with the completed project. Sources of repayment for these types of loans may be pre-committed permanent loans from other lenders, sales of developed property, or an interim loan commitment from us until permanent financing is obtained. The nature of these loans makes ultimate repayment extremely sensitive to overall economic conditions. Borrowers may not be able to correct conditions of default in loans, increasing risk of exposure to classification, non-performing status, reserve allocation and actual credit loss and foreclosure. These loans typically have floating rates and commitment fees. At December 31, 2014, funded construction real estate loans totaled approximately $1.4 billion, approximately 10% of our total funded loans.

Real Estate Loans.    Approximately 24% of our real estate loan portfolio (excluding construction loans) and 5% of the total portfolio is comprised of loans secured by properties other than market risk or investment-type real estate. Market risk loans are real estate loans where the primary source of repayment is expected to come from the sale or lease of the real property collateral. We generally provide temporary financing for commercial and residential property. These loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Our real estate loans generally have maximum terms of five to seven years, and we provide loans with both floating and fixed rates. We generally avoid long-term loans for commercial real estate held for investment. Real estate loans may be more adversely affected by conditions in the real estate markets and in the

34

general economy than other types of loans. Appraised values may be highly variable due to market conditions and the impact of the inability of potential purchasers and lessees to obtain financing and lack of transactions at comparable values. At December 31, 2014, real estate term loans totaled approximately $2.8 billion, or 20% of our total funded loans.

Letters of Credit.    We issue standby and commercial letters of credit, and can service the international needs of our clients through correspondent banks. At December 31, 2014, our commitments under letters of credit totaled approximately $177.8 million.

Portfolio Geographic and Industry Concentrations

As of December 31, 2014, a majority of our loans held for investment, excluding our mortgage finance loans and other national lines of business, were to businesses with headquarters and operations in Texas. This geographic concentration subjects the loan portfolio to the general economic conditions within this area. Additionally, we may make loans to these businesses and individuals, secured by assets located outside of Texas. The risks created by this concentration have been considered by management in the determination of the adequacy of the allowance for loan losses. Management believes the allowance for loan losses is appropriate to cover estimated losses on loans at each balance sheet date.

The table below summarizes the industry concentrations of our funded loans at December 31, 2014.

(in thousands except percentage data)	Amount		Percent of Total Loans
Services	$	5,141,989	35.9	%

Agriculture	18,106		0.1	%
Total	$	14,314,070	100.0	%

Excluding our mortgage finance business, our largest concentration in any single industry is in services. Loans extended to borrowers within the services industries include loans to finance working capital and equipment, as well as loans to finance investment and owner-occupied real estate. Significant trade categories represented within the services industries include, but are not limited to, real estate services, financial services, leasing companies, transportation and communication, and hospitality services. Borrowers represented within the real estate services category are largely owners and managers of both residential and non-residential commercial real estate properties. Loans extended to borrowers within the contracting industry are comprised largely of loans to land developers and to both heavy construction and general commercial contractors. Many of these loans are secured by real estate properties, the development of which is or may be financed by our bank. Loans extended to borrowers within the petrochemical and mining industries are predominantly loans to finance the exploration and production of petroleum and natural gas. These loans are generally secured by proven petroleum and natural gas reserves and any such reserves which are developed as a result of the exploration. Additionally, there are loans secured by business assets to companies in the energy services business, where such loans generally relate to production, not exploration, drilling and development of reserves. We also have a small number of loans where our collateral consists of partnership interests and the partnerships are primarily in the petrochemical and mining industry. Personal/household loans include loans to certain successful professionals and entrepreneurs for commercial purposes, in addition to consumer loans.

We make loans that are appropriately collateralized under our credit standards. Approximately 98% of our funded loans are secured by collateral. Over 87% of the real estate collateral is located in Texas. The table below sets forth information regarding the distribution of our funded loans among various types of collateral at December 31, 2014 (in thousands except percentage data):

We extend market risk real estate loans, including both construction/development financing and limited term financing, to professional real estate developers and owners/managers of commercial real estate projects and properties who have a demonstrated record of past success with similar properties. Collateral properties include office buildings, warehouse/distribution buildings, shopping centers, apartment buildings, residential and commercial tract development located primarily within our five major metropolitan markets in Texas. These loans are generally repaid through the borrowers’ sale or lease of the properties, and loan amounts are determined in part from an analysis of pro forma cash flows. Loans are also underwritten to comply with product-type specific advance rates against both cost and market value. We engage a variety of professional firms to supply appraisals, market studies and feasibility reports, environmental assessments and project site inspections to complement our internal resources to underwrite and monitor these credit exposures.

The determination of collateral value is critically important when financing real estate. As a result, obtaining current and objectively prepared appraisals is a major part of our underwriting and monitoring processes. Generally, our policy requires a new appraisal every three years. However, in periods of economic uncertainty where real estate values can fluctuate rapidly as in recent years, more current appraisals are obtained when warranted by conditions such as a borrower’s deteriorating financial condition, their possible inability to perform on the loan, and the increased risks involved with reliance on the collateral value as sole repayment of the loan. Generally, loans graded substandard or worse where real estate is a material portion of the collateral value and/or the income from the real estate or sale of the real estate is the primary source of debt service, annual appraisals are obtained. In all cases, appraisals are reviewed by a third party to determine reasonableness of the appraised value. The third party reviewer will challenge whether or not the data used is appropriate and relevant, form an opinion as to the appropriateness of the appraisal methods and techniques used, and determine if overall the analysis and conclusions of the appraiser can be relied upon. Additionally, the third party reviewer provides a detailed report of that analysis. Further review may be conducted by our credit officers, as well as by the Bank’s managed asset committee as conditions warrant. These additional steps of review ensure that the underlying appraisal and the third party analysis can be relied upon. If we have differences, we will address those with the reviewer and determine the method to resolve any differences. Both the appraisal process and the appraisal review process can be difficult during and following periods of economic weakness due to the lack of comparable sales which is partially a result of the lack of available financing that can lead to overall depressed real estate values.

Large Credit Relationships

The primary market areas we serve include the five major metropolitan markets of Texas, including Austin, Dallas, Fort Worth, Houston and San Antonio. We originate and maintain large credit relationships with numerous customers in the ordinary course of business. The legal limit of our bank is approximately $264 million and our house limit is generally $25 million or less. Larger hold positions will be accepted occasionally for exceptionally strong borrowers and otherwise where business opportunity and perceived credit risk warrant a somewhat larger investment. We consider large credit relationships to be those with commitments equal to or in excess of $10.0 million. The following table provides additional information on our large credit relationships outstanding at year-end (in thousands):

	December 31, 2014					December 31, 2013
		Period End Balances					Period End Balances
	Number of Relationships	Committed		Outstanding		Number of Relationships	Committed		Outstanding
$20.0 million and greater	206	$	5,589,823	$	2,966,627	141	$	3,694,305	$	2,213,744

Growth in period end outstanding balances related to large credit relationships primarily resulted from an increase in number of commitments. The following table summarizes the average per relationship committed and average outstanding loan balance related to our large credit relationships at year-end (in thousands):

	2014 Average Balance				2013 Average Balance

Interest Reserve Loans

As of December 31, 2014, we had $379.2 million in loans with interest reserves, which represents approximately 27% of our construction loans. Loans with interest reserves are common when originating construction loans, but the use of interest reserves is carefully controlled by our underwriting standards. The use of interest reserves is based on the feasibility of the project, the creditworthiness of the borrower and guarantors, and the loan to value coverage of the collateral. The interest reserve account allows the borrower, when financial condition precedents are met to draw loan funds to pay interest charges on the outstanding balance of the loan. When drawn, the interest is capitalized and added to the loan balance, subject to conditions specified at the time the credit is approved and during the initial underwriting. We have effective and ongoing controls for monitoring compliance with loan covenants for advancing funds and determination of default conditions. When lending relationships involve financing of land on which improvements will be constructed, construction funds are not advanced until the borrower has received lease or purchase commitments which will meet cash flow coverage requirements, and/or our analysis of market conditions and project feasibility indicates to management’s satisfaction that such lease or purchase commitments are forthcoming or other sources of repayment have been identified to repay the loan. We maintain current financial statements on the borrowing entity and guarantors, as well as conduct periodic inspections of the project and analysis of whether the project is on schedule or delayed. Updated appraisals are ordered when necessary to validate the collateral values to support all advances, including reserve interest. Advances of interest reserves are discontinued if collateral values do not support the advances or if the borrower does not comply with other terms and conditions in the loan agreements. In addition, most of our construction lending is performed in Texas and our lenders are very familiar with trends in local real estate. If at any time we believe that our collateral position is jeopardized, we retain the right to stop the use of the interest reserves. As of December 31, 2014, none of our loans with interest reserves were on non-accrual.

Loans past due 90 days and accruing(2)	$	5,274	$	9,325	$	3,674

(1) The accrual of interest on loans is discontinued when there is a clear indication that the borrower’s cash flow may not be sufficient to meet payments as they become due, which is generally when a loan is 90 days past due. When a loan is placed on non-accrual status, all previously accrued and unpaid interest is reversed. Interest income is subsequently recognized on a cash basis as long as the remaining unpaid principal amount of the loan is deemed to be fully collectible. If collectability is questionable, then cash payments are applied to principal. If these loans had been current throughout their terms, interest and fees on loans would have increased by approximately $2.1 million, $2.5 million and $2.4 million for the years ended December 31, 2014, 2013 and 2012, respectively.

(2) At December 31, 2014, 2013 and 2012, loans past due 90 days and still accruing includes premium finance loans of $3.7 million, $3.8 million and $2.8 million, respectively. These loans are generally secured by obligations of insurance carriers to refund premiums on cancelled insurance policies. The refund of premiums from the insurance carriers can take 180 days or longer from the cancellation date.

(3) At December 31, 2014 and 2013, there is no valuation allowance recorded against the OREO balance. At December 31, 2012, the OREO balance is net of $5.6 valuation allowance.

(4) As of December 31, 2014, 2013 and 2012, non-accrual loans included $12.1 million, $17.8 million and $19.6 million, respectively, in loans that met the criteria for restructured.

Total non-performing assets at December 31, 2014 increased $6.4 million from December 31, 2013, compared to a $34.4 million decrease from December 31, 2012 to December 31, 2013. We experienced a modest increase in levels of nonperforming assets in 2014 compared to a decrease in 2013 and an overall improvement in credit quality. Our provision for credit losses increased as a result of the significant growth in the loans held for investment, excluding mortgage finance loans. This growth resulted in a decrease in the reserve for loan losses as a percent of loans excluding mortgage finance loans for 2014 as compared to 2013.

Reserves on impaired loans were $8.4 million at December 31, 2014, compared to $3.2 million at December 31, 2013 and $3.9 million at December 31, 2012. We recognized $1.7 million in interest income on non-accrual loans during 2014 compared to $2.4 million in 2012 and $2.6 million in 2012. Additional interest income that would have been recorded if the loans had been current during the years ended December 31, 2014, 2013 and 2012 totaled $2.1 million, $2.5 million and $2.4 million, respectively. Average impaired loans outstanding during the years ended December 31, 2014, 2013 and 2012 totaled $49.3 million, $40.0 million and $66.4 million, respectively.

Generally, we place loans on non-accrual when there is a clear indication that the borrower’s cash flow may not be sufficient to meet payments as they become due, which is generally when a loan is 90 days past due. When a loan is placed on non-accrual status, all previously accrued and unpaid interest is reversed. Interest income is subsequently recognized on a cash basis as long as the remaining unpaid principal amount of the loan is deemed to be fully collectible. If collectability is questionable, then cash payments are applied to principal. As of December 31, 2014, $310,000 of our non-accrual loans were earning on a cash basis. A loan is placed back on accrual status when both principal and interest are current and it is probable that we will be able to collect all amounts due (both principal and interest) according to the terms of the loan agreement.

A loan is considered impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due (both principal and interest) according to the terms of the original loan agreement. Reserves on impaired loans are measured based on the present value of the expected future cash flows discounted at the loan’s effective interest rate or the fair value of the underlying collateral.

At December 31, 2014, we had $5.3 million in loans past due 90 days and still accruing interest. Of this total, $3.7 million are premium finance loans. These loans are primarily secured by obligations of insurance carriers to refund premiums on cancelled insurance policies. The refund of premiums from the insurance carriers can take 180 days or longer from the cancellation date.

Restructured loans are loans on which, due to the borrower’s financial difficulties, we have granted a concession that we would not otherwise consider. This may include a transfer of real estate or other assets from the borrower, a modification of loan terms, or a combination of the two. Modifications of terms that could potentially qualify as a restructuring include reduction of contractual interest rate, extension of the maturity date at a contractual interest rate lower than the current rate for new debt with similar risk, or a reduction of the face amount of debt, or forgiveness of either principal or accrued interest. As of December 31, 2014 we have $1.8 million in loans considered restructured that are not on non-accrual. These loans do not have unfunded commitments at December 31, 2014. Of the non-accrual loans at December 31, 2014, $12.1 million met the criteria for restructured. A loan continues to qualify as restructured until a consistent payment history or change in borrower's financial condition has been evidenced, generally no less than twelve months. Assuming that the restructuring agreement specifies an interest rate at the time of the restructuring that is greater than or equal to the rate that we are willing to accept for a new extension of credit with comparable risk, then the loan no longer has to be considered a restructuring if it is in compliance with modified terms in calendar years after the year of the restructuring.

40

Potential problem loans consist of loans that are performing in accordance with contractual terms, but for which we have concerns about the borrower’s ability to comply with repayment terms because of the borrower’s potential financial difficulties. We monitor these loans closely and review their performance on a regular basis. At December 31, 2014 and 2013, we had $16.3 million and $47.9 million, respectively, in loans of this type which were not included in either non-accrual or 90 days past due categories.

When foreclosure occurs, fair value, which is generally based on appraised values, may result in partial charge-off of a loan upon taking property, and so long as the property is retained, reductions in appraised values will result in valuation adjustments taken as non-interest expense. In addition, if the decline in value is believed to be permanent and not just driven by market conditions, a direct write-down to the OREO balance may be taken. We generally pursue sales of OREO when conditions warrant, but we may choose to hold certain properties for a longer term, which can result in additional exposure related to the appraised values during that holding period. We did not record a valuation expense during the year ended December 31, 2014 compared to $920,000 recorded during the same period of 2013. Of the $920,000 recorded for the year ended December 31, 2013, $1.9 million related to direct write-downs, offset by a reduction in the valuation allowance of $958,000.

Summary of Loan Loss Experience

The provision for loan losses is a charge to earnings to maintain the reserve for loan losses at a level consistent with management’s assessment of the collectability of the loan portfolio in light of current economic conditions and market trends. We recorded a provision for credit losses of $22.0 million for the year ended December 31, 2014, $19.0 million for the year ended December 31, 2013, and $11.5 million for the year ended December 31, 2012. The increase in provision recorded during 2014 is directly related to the significant growth in loans excluding mortgage finance loans. We remained consistent in all credit quality ratios during 2014 and experienced improvements during 2013 and 2012.

The reserve for loan losses is comprised of specific reserves for impaired loans and an estimate of losses inherent in the portfolio at the balance sheet date, but not yet identified with specified loans. We regularly evaluate our reserve for loan losses to maintain an appropriate level to absorb estimated loan losses inherent in the loan portfolio. Factors contributing to the determination of reserves include the creditworthiness of the borrower, changes in the value of pledged collateral, and general economic conditions. All loan commitments rated substandard or worse and greater than $500,000 are specifically reviewed for loss potential. For loans deemed to be impaired, a specific allocation is assigned based on the losses expected to be realized from those loans. For purposes of determining the general reserve, the portfolio is segregated by product types to recognize differing risk profiles among categories, and then further segregated by credit grades. Credit grades are assigned to all loans. Each credit grade is assigned a risk factor, or reserve allocation percentage. These risk factors are multiplied by the outstanding principal balance and risk-weighted by product type to calculate the required reserve. A similar process is employed to calculate a reserve assigned to off-balance sheet commitments, specifically unfunded loan commitments and letters of credit. Even though portions of the allowance may be allocated to specific loans, the entire allowance is available for any credit that, in management’s judgment, should be charged off.

The reserve allocation percentages assigned to each credit grade have been developed based primarily on an analysis of our historical loss rates. The allocations are adjusted for certain qualitative factors, including general economic conditions, changes in credit policies and lending standards. Changes in the trend and severity of problem loans can cause the estimation of losses

41

to differ from past experience. In addition, the reserve considers the results of reviews performed by independent third party reviewers as reflected in their confirmations of assigned credit grades within the portfolio. The portion of the allowance that is not derived by the allowance allocation percentages compensates for the uncertainty and complexity in estimating loan and lease losses including factors and conditions that may not be fully reflected in the determination and application of the allowance allocation percentages. Examples of risks that support the Bank's maintaining an unallocated reserve include the possibility of precipitous negative changes in economic conditions and borrowers' submission of financial statements or certifications of collateral value that subsequently prove to be materially inaccurate for reason of either misstatement or omission of critical information. These situations, while not common, do not necessarily correlate well with the general risk profile presented by assigned credit grade and product type categories. We evaluate many such factors and conditions in determining the unallocated portion of the allowance, including amount and frequency of losses attributable to issues not specifically addressed or included in the determination and application of the allowance allocation percentages. The allowance is considered appropriate, given management’s assessment of potential losses within the portfolio as of the evaluation date, the significant growth in the loan and lease portfolio, current economic conditions in the Company’s market areas and other factors.

The methodology used in the periodic review of reserve adequacy, which is performed at least quarterly, is designed to be dynamic and responsive to changes in portfolio credit quality. The changes are reflected in the general reserve and in specific reserves as the collectability of larger classified loans is evaluated with new information. As our portfolio has matured, historical loss ratios have been closely monitored, and our reserve adequacy relies primarily on our loss history. The review of reserve adequacy is performed by executive management and presented to a committee of our board of directors for their review. The committee reports to the board as part of the board's review on a quarterly basis of the Company's consolidated financial statements.

The reserve for credit losses, which includes a liability for losses on unfunded commitments, totaled $108.0 million at December 31, 2014, $92.3 million at December 31, 2013 and $78.2 million at December 31, 2012. The total reserve percentage decreased to 1.06% at year-end 2014 from 1.09% and 1.15% of loans excluding mortgage finance loans at December 31, 2013 and 2012, respectively. The combined reserve has trended down during 2012, 2013 and 2014 as we recognize losses on loans for which there were specific or general allocations of reserves and see improvement in our overall credit quality. The overall reserve for loan losses continued to result from consistent application of the loan loss reserve methodology as described above. At December 31, 2014, we believe the reserve is sufficient to cover all expected losses in the portfolio and has been derived from consistent application of the methodology described above. Should any of the factors considered by management in evaluating the adequacy of the allowance for loan losses change, our estimate of expected losses in the portfolio could also change, which would affect the level of future provisions for loan losses.

(1) The accrual of interest on loans is discontinued when there is a clear indication that the borrower’s cash flow may not be sufficient to meet payments as they become due, which is generally when a loan is 90 days past due. When a loan is placed on non-accrual status, all previously accrued and unpaid interest is reversed. Interest income is subsequently recognized on a cash basis as long as the remaining unpaid principal amount of the loan is deemed to be fully collectible. If collectability is questionable, then cash payments are applied to principal. If these loans had been current throughout their terms, interest and fees on loans would have increased by approximately $2.1 million, $2.5 million and $2.4 million for the years ended December 31, 2014, 2013 and 2012, respectively.

(2) At December 31, 2014, 2013 and 2012, loans past due 90 days and still accruing includes premium finance loans of $3.7 million, $3.8 million and $2.8 million, respectively. These loans are generally secured by obligations of insurance carriers to refund premiums on cancelled insurance policies. The refund of premiums from the insurance carriers can take 180 days or longer from the cancellation date.

(3) At December 31, 2014 and 2013, we did not have a valuation allowance recorded against the OREO balance. At December 31, 2012, OREO balance was net of a $5.6 million valuation allowance.

(4) As of December 31, 2014, 2013 and 2012, non-accrual loans included $12.1 million, $17.8 million and $19.6 million, respectively, in loans that met the criteria for restructured.

(1) No amount of the reserve is allocated to these loans based on the internal risk grade assigned.

Increases in the reserve allocated to loan categories are due primarily to the significant growth in the overall loan portfolio. We have traditionally maintained an unallocated reserve component to allow for uncertainty in economic and other conditions affecting the quality of the loan portfolio. The unallocated portion of our loan loss reserve has decreased since December 31, 2012. We believe the level of unallocated reserves at December 31, 2014 continues to be warranted due to the continued uncertain economic environment which has produced more frequent losses, including those resulting from fraud by borrowers. Our methodology used to calculate the allowance considers historical losses, however, the historical loss rates for specific product types or credit risk grades may not fully incorporate the effects of continued weakness in the economy.

Securities Portfolio

Securities are identified as either held-to-maturity or available-for-sale based upon various factors, including asset/liability management strategies, liquidity and profitability objectives, and regulatory requirements. Held-to-maturity securities are carried at cost, adjusted for amortization of premiums or accretion of discounts. Available-for-sale securities are securities that may be sold prior to maturity based upon asset/liability management decisions. Securities identified as available-for-sale are carried at fair value. Unrealized gains or losses on available-for-sale securities are recorded as accumulated other comprehensive income (loss) in stockholders’ equity, net of taxes. Amortization of premiums or accretion of discounts on mortgage-backed securities is periodically adjusted for estimated prepayments. Realized gains and losses and declines in value judged to be other-than-temporary are included in gain (loss) on sale of securities. The cost of securities sold is based on the specific identification method.

During the year ended December 31, 2014, we maintained an average securities portfolio of $49.2 million compared to an average portfolio of $77.2 million for the same period in 2013 and $117.4 million for the same period in 2012. At December 31, 2014 and 2013, the portfolios were primarily comprised of mortgage-backed securities. Of the mortgage-backed securities, substantially all are guaranteed by U.S. government agencies. Our portfolio included no impaired securities during 2014 and 2013.

Our net unrealized gain on the securities portfolio value decreased due to the reduction in balances held from a net gain of $2.5 million, which represented 4.13% of the amortized cost, at December 31, 2013, to a net gain of $2.0 million, which represented 4.99% of the amortized cost, at December 31, 2014. During 2013, the unrealized gain on the securities portfolio value decreased, also as a result of the reduced balances held, from a net gain of $5.0 million, which represented 5.29% of the amortized cost, at December 31, 2012, to a net gain of $2.5 million, which represented 4.13% of the amortized cost, at December 31, 2013. Changes in value reflect changes in market interest rates and the total balance of securities.

The average expected life of the mortgage-backed securities was 1.2 years at December 31, 2014 and 1.4 years at December 31, 2013. The effect of possible changes in interest rates on our earnings and equity is discussed under “Interest Rate Risk Management.”

(1) Actual maturities may differ significantly from contractual maturities because borrowers may have the right to call or prepay obligations with or without prepayment penalties.

(2) Yields have been adjusted to a tax equivalent basis assuming a 35% federal tax rate.

(3) Yields are calculated based on amortized cost.

(4) These equity securities do not have a stated maturity.

The fair value of investment securities is based on prices obtained from independent pricing services which are based on quoted market prices for the same or similar securities. We have obtained documentation from the primary pricing service we use about their processes and controls over pricing. In addition, on a quarterly basis we independently verify the prices that we receive from the service provider using two additional independent pricing sources. Any significant differences are investigated and resolved.

The following table discloses, as of December 31, 2014 and 2013, our investment securities that have been in a continuous unrealized loss position for less than 12 months and those that have been in a continuous unrealized loss position for 12 or more months (in thousands):

At December 31, 2014 and 2013, we had one investment with an unrealized loss position. This security is a publicly traded equity fund and is subject to market pricing volatility. We do not believe that these unrealized losses are “other than temporary”. We have evaluated the near-term prospects of the investment in relation to the severity and duration of the impairment and based on that evaluation have the ability and intent to hold the investment until recovery of fair value. We have not identified any issues related to the ultimate recovery of our investment as a result of credit concerns on this security.

Deposits

We compete for deposits by offering a broad range of products and services to our customers. While this includes offering competitive interest rates and fees, the primary means of competing for deposits is convenience and service to our customers. However, our strategy to provide service and convenience to customers does not include a large branch network. Our bank offers thirteen banking centers, courier services and online banking. BankDirect, the Internet division of our bank, serves its customers on a 24 hours-a-day, 7 days-a-week basis solely through Internet banking.

Average deposits for the year ended December 31, 2014 increased $2.5 billion compared to the same period of 2013. Average demand deposits, interest-bearing transaction deposits, savings deposits and time deposits (including deposits in foreign branches) increased by $1.2 billion, $52.4 million, $1.2 billion and $35.7 million, respectively. The average cost of deposits remained level at .17% in 2014 as compared to 2013 mainly due to our focused effort to reduce rates paid on deposits and the significant increase in non-interest-bearing deposits during 2014.

Average deposits for the year ended December 31, 2013 increased $1.9 billion compared to the same period of 2012. Average demand deposits, interest-bearing transaction deposits and savings deposits increased by $982.9 million, $156.4 million and $991.5 million, respectively, while time deposits (including deposits in foreign branches) decreased $199.9 million during the year ended December 31, 2013 as compared to the same period of 2012. The average cost of deposits decreased in 2013 mainly due to our focused effort to reduce rates paid on deposits and the significant increase in non-interest-bearing deposits during 2013.

The following table discloses our average deposits for the years ended December 31, 2014, 2013 and 2012 (in thousands):

	Average Balances
	2014		2013		2012
Non-interest-bearing	$	4,188,173	$	2,967,063	$	1,984,171

Total average deposits	$	10,865,544	$	8,374,873	$	6,444,007

As with our loan portfolio, a majority of our deposits are from businesses and individuals in Texas. As of December 31, 2014, approximately 82% of our deposits originated out of our Dallas metropolitan banking centers. Uninsured deposits at December 31, 2014 were 72% of total deposits, compared to 67% of total deposits at December 31, 2013 and 50% of total deposits at December 31, 2012. The presentation for 2014, 2013 and 2012 does reflect combined ownership, but does not reflect all of the account styling that would determine insurance based on FDIC regulations.

At December 31, 2014, we had $311.1 million in interest-bearing time deposits of $100,000 or more in foreign branches related to our Cayman Islands branch. All deposits in the Cayman Branch come from U.S. based customers of our Bank. Deposits do not originate from foreign sources, and funds transfers neither come from nor go to facilities outside of the U.S. All deposits are in U.S. dollars.

Liquidity and Capital Resources

In general terms, liquidity is a measurement of our ability to meet our cash needs. Our objective in managing our liquidity is to maintain our ability to meet loan commitments, purchase securities or repay deposits and other liabilities in accordance with their terms, without an adverse impact on our current or future earnings. Our liquidity strategy is guided by policies, which are formulated and monitored by our senior management and our Balance Sheet Management Committee (“BSMC”), and which take into account the demonstrated marketability of assets, the sources and stability of funding and the level of unfunded commitments. We regularly evaluate all of our various funding sources with an emphasis on accessibility, stability, reliability and cost-effectiveness. For the years ended December 31, 2014 and 2013, our principal source of funding has been our customer deposits, supplemented by our short-term and long-term borrowings, primarily from Federal Funds purchased and Federal Home Loan Bank (“FHLB”) borrowings, generally used to fund mortgage finance assets.

Our liquidity needs for support of growth in loans have been fulfilled through growth in our core customer deposits. Our goal is to obtain as much of our funding for loans held for investment and other earning assets as possible from deposits of these core customers. These deposits are generated principally through development of long-term relationships with customers and stockholders, with a significant focus on treasury management products. In addition to deposits from our core customers, we also have access to deposits through brokered customer relationships. For regulatory purposes, these relationship brokered deposits are now categorized as brokered deposits; however, since these deposits arise from a customer relationship which involves extensive treasury services, we consider these deposits to be core deposits for our reporting purposes. We also have access to incremental deposits through brokered retail certificates of deposit, or CDs. These traditional brokered deposits are generally of short maturities, 30 to 90 days, and are used to supplement temporary differences in the growth in loans, including growth in loans held for sale or other specific categories of loans, compared to customer deposits. The following table summarizes our period-end and average year-to-date core customer deposits and brokered deposits (in millions):

	December 31,
	2014			2013
Deposits from core customers	$	10,900.0		$	7,840.1
Deposits from core customers as a percent of total deposits	86.0		%	84.7		%
Relationship brokered deposits	$	1,773.3		$	1,417.3
Relationship brokered deposits as a percent of average total deposits	14.0		%	15.3		%
Traditional brokered deposits	$	—		$	—
Traditional brokered deposits as a percent of total deposits	—		%	—		%

Average traditional brokered deposits	$	20.7		$	—
Average traditional brokered deposits as a percent of average total deposits	0.2		%	—		%

We have access to sources of brokered deposits that we estimate to be $3.5 billion. Based on our internal guidelines, we may choose to limit our use of these sources to a lesser amount. Customer deposits (total deposits, including relationship brokered deposits, minus brokered CDs) at December 31, 2014 increased $3.4 billion from December 31, 2013.

48

Additionally, we have short-term borrowing sources available to supplement deposits and meet our funding needs. Such borrowings are generally used to fund our mortgage finance loans, due to their liquidity, short duration and interest spreads available. These borrowing sources include Federal funds purchased from our downstream correspondent bank relationships (which consist of banks that are smaller than our bank) and from our upstream correspondent bank relationships (which consist of banks that are larger than our bank), customer repurchase agreements, treasury, tax and loan notes and advances from the FHLB and the Federal Reserve. The following table summarizes our borrowings (in thousands):

	2014						2013						2012
	Balance		Rate(3)		Maximum Outstanding at Any Month End		Balance		Rate(3)		Maximum Outstanding at Any Month End		Balance		Rate(3)		Maximum Outstanding at Any Month End
Federal funds purchased(4)	$	66,971	0.30	%			$	148,650	0.22	%			$	273,179	0.26	%
Customer repurchase agreements(1)	25,705		0.38	%			21,954		0.31	%			23,936		0.04	%
FHLB borrowings (2)	1,100,005		0.13	%			840,026		0.12	%			1,650,046		0.09	%
Total borrowings	$	1,192,681			$	1,192,681	$	1,010,630			$	1,634,630	$	1,947,161			$	2,208,539

(1) Securities pledged for customer repurchase agreements were $21.8 million, $37.7 million and $23.9 million at December 31, 2014, 2013 and 2012, respectively.

(2) FHLB borrowings are collateralized by a blanket floating lien on certain real estate-secured loans, mortgage finance assets and also certain pledged securities. The weighted-average interest rate for the years ended December 31, 2014, 2013 and 2012 was 0.15%, 0.14% and 0.16%, respectively. The average balance of FHLB borrowings for the years ended December 31, 2014, 2013 and 2012 was $213.4 million, $370.0 million and $1.2 billion, respectively.

(3) Interest rate as of period end.

(4) The weighted-average interest rate on federal funds purchased for the years ended December 31, 2014, 2013 and 2012 was 0.27%, 0.27% and 0.28%, respectively. The average balance of federal funds purchased for the years ended December 31, 2014, 2013 and 2012 was $139.3 million, $254.3 million and $350.8 million, respectively.

The following table summarizes our other borrowing capacities in excess of balances outstanding (in thousands):

	2014		2013		2012
FHLB borrowing capacity relating to loans	$	3,602,994	$	693,302	$	267,542
FHLB borrowing capacity relating to securities	535		8,482		33,204
Total FHLB borrowing capacity	$	3,603,529	$	701,784	$	300,746
Unused Federal funds lines available from commercial banks	$	1,186,000	$	890,000	$	706,000
Unused Federal Reserve Borrowings capacity	$	2,643,000	$	2,284,000	$	1,940,000

From time to time, we borrow funds on an overnight basis from the Federal Reserve. We did not incur such borrowings during 2014, and during 2013, we did so on one such occasion when mortgage finance loan balances surged at the end of a month. At December 31, 2014 and 2013, no borrowings from the Federal Reserve were outstanding. Fed borrowings for the year ended December 31, 2013 averaged $55,000.

We had an existing non-revolving amortizing line of credit with $100.0 million of unused capacity that matured on December 15, 2014. This line of credit was renewed on December 23, 2014 with a new maturity date of December 22, 2015. The loan proceeds may be used for general corporate purposes including funding regulatory capital infusions into the Bank. The loan agreement contains customary financial covenants and restrictions. As of December 31, 2014, no borrowings were outstanding compared to $15.0 million outstanding at December 31, 2013.

From November 2002 to September 2006 various Texas Capital Statutory Trusts were created and subsequently issued floating rate trust preferred securities in various private offerings totaling $113.4 million. After deducting underwriter’s compensation and other expenses of each offering, the net proceeds were available to the Company to increase capital and for general corporate purposes, including use in investment and lending activities. Interest payments on all trust preferred subordinated debentures are deductible for federal income tax purposes. As of December 31, 2014, the weighted average quarterly rate on the trust preferred subordinated debentures was 2.19%, compared to 2.19% average for all of 2014, and 2.24% for all of 2013.

Because our bank had less than $15.0 billion in total consolidated assets as of December 31, 2009, we are allowed to continue to classify our trust preferred securities, all of which were issued prior to May 19, 2010, as Tier 1 capital. Our equity capital averaged $1.3 billion for the year ended December 31, 2014 as compared to $1.0 billion in 2013 and $713.2 million in 2012. We have not paid any cash dividends on our common stock since we commenced operations and have no plans to do so in the foreseeable future.

On March 28, 2013, we completed a sale of 6.0 million shares of our 6.50% non-cumulative preferred stock, par value $0.01, with a liquidation preference of $25 per share, in a public offering. Dividends on the preferred stock are not cumulative and will be paid when declared by our board of directors to the extent that we have lawfully available funds to pay dividends. If declared, dividends will accrue and be payable quarterly, in arrears, on the liquidation preference amount, on a non-cumulative basis, at a rate of 6.50% per annum. We paid $9.8 million in dividends on the preferred stock for the year ended December 31, 2014. Holders of preferred stock will not have voting rights, except with respect to authorizing or increasing the authorized amount of senior stock, certain changes in terms of the preferred stock, certain dividend non-payments and as otherwise required by applicable law. Net proceeds from the sale totaled $145.0 million. The additional equity was used for general corporate purposes, including funding regulatory capital infusions into the Bank.

In January 2014, we completed an offering of 1.9 million shares of our common stock. Net proceeds from the sale totaled $106.5 million. On January 31, 2014, the Bank issued $175.0 million of subordinated notes in an offering to institutional investors exempt from registration under Section 3(a)(2) of the Securities Act of 1933 and 12 C.F.R. Part 16. Net proceeds from the transaction were $172.4 million. The notes mature in January 2026 and bear interest at a rate of 5.25% per annum, payable semi-annually. The notes are unsecured and are subordinate to the Bank’s obligations to its depositors, its obligations under banker’s acceptances and letters of credit, certain obligations to Federal Reserve Banks and the FDIC and the Bank’s obligations to its other creditors, except any obligations which expressly rank on a parity with or junior to the notes. The notes qualify as Tier 2 capital for regulatory capital purposes, subject to applicable limitations. The net proceeds of both offerings were used by the Company for general corporate purposes, including retirement of $15.0 million of short-term debt that was outstanding at December 31, 2013, and additional capital to support continued loan growth.

On November 12, 2014, we completed a sale of 2.5 million shares of our common stock in a public offering. Net proceeds from the sale totaled $149.6 million. The additional equity was used for general corporate purposes and additional capital to support continued loan growth.

In July 2013, the Federal Reserve published final rules for the adoption of the Basel III regulatory capital framework (the "Basel III Capital Rules"). The Basel III Capital Rules, among other things, (i) introduce a new capital measure called "Common Equity Tier 1," (ii) specify that Tier 1 capital consist of Common Equity Tier 1 and "Additional Tier 1 Capital" instruments meeting specified requirements, (iii) define Common Equity Tier 1 narrowly by requiring that most deductions/adjustments to regulatory capital measures be made to Common Equity Tier 1 and not to the other components of capital and (iv) expand the scope of the deductions/adjustments as compared to existing regulations. The Basel III Capital Rules became effective for us on January 1, 2015 with certain transition provisions fully phased in on January 1, 2019. Based on our initial assessment of the Basel III Capital Rules, we do not believe they will have a material impact on the Company or our bank. We believe we will meet the capital adequacy requirements under the Basel III Capital Rules on a fully phased-in basis when we commence filing 2015 reports with the FDIC and OCC.

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 table below) of total and Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital (as defined) to average assets (as defined). Management believes, as of December 31, 2014, that the Company and the Bank meet all capital adequacy requirements to which they are subject.

Financial institutions are categorized as well capitalized or adequately capitalized, based on minimum total risk-based, Tier 1 risk-based and Tier 1 leverage ratios. As shown in the table below, the Company’s capital ratios exceed the regulatory definition of adequately capitalized as of December 31, 2014 and 2013. Based upon the information in its most recently filed call report, the Bank met the capital ratios necessary to be well capitalized. The regulatory authorities can apply changes in classification of assets and such change may retroactively subject the Company to change in capital ratios. Any such change could result in reducing one or more capital ratios below well-capitalized status. In addition, a change may result in imposition of additional assessments by the FDIC or could result in regulatory actions that could have a material effect on condition and results of operations.

Dividends that may be paid by subsidiary banks are routinely restricted by various regulatory authorities. The amount that can be paid in any calendar year without prior approval of the Bank's regulatory agencies cannot exceed the lesser of the net profits (as defined) for that year plus the net profits for the preceding two calendar years, or retained earnings. The Basel III Capital Rules will further limit the amount of dividends that may be paid by our bank. No dividends were declared or paid on our common stock during the year ended December 31, 2014 or 2013.

Critical Accounting Policies

SEC guidance requires disclosure of “critical accounting policies.” The SEC defines “critical accounting policies” as those that are most important to the presentation of a company’s financial condition and results, and require management’s most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain.

We follow financial accounting and reporting policies that are in accordance with accounting principles generally accepted in the United States. The more significant of these policies are summarized in Note 1 to the consolidated financial statements. Not all these significant accounting policies require management to make difficult, subjective or complex judgments. However, the policy noted below could be deemed to meet the SEC’s definition of a critical accounting policy.

52

Management considers the policies related to the allowance for loan losses as the most critical to the financial statement presentation. The total allowance for loan losses includes activity related to allowances calculated in accordance with Accounting Standards Codification (“ASC”) 310, Receivables, and ASC 450, Contingencies. The allowance for loan losses is established through a provision for loan losses charged to current earnings. The amount maintained in the allowance reflects management’s continuing evaluation of the loan losses inherent in the loan portfolio. The allowance for loan losses is comprised of specific reserves assigned to certain classified loans and general reserves. Factors contributing to the determination of specific reserves include the creditworthiness of the borrower, and more specifically, changes in the expected future receipt of principal and interest payments and/or in the value of pledged collateral. A reserve is recorded when the carrying amount of the loan exceeds the discounted estimated cash flows using the loan’s initial effective interest rate or the fair value of the collateral for certain collateral dependent loans. For purposes of determining the general allowance, the portfolio is segregated by product types in order to recognize differing risk profiles among categories, and then further segregated by credit grades. See “Summary of Loan Loss Experience” and Note 3 – Loans and Allowance for Loan Losses in the accompanying notes to the consolidated financial statements included elsewhere in this report for further discussion of the risk factors considered by management in establishing the allowance for loan losses.

New Accounting Standards

See Note 22 – New Accounting Standards in the accompanying notes to the consolidated financial statements included elsewhere in this report for details of recently issued accounting pronouncements and their expected impact on our financial statements.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

Market risk is a broad term for the risk of economic loss due to adverse changes in the fair value of a financial instrument. These changes may be the result of various factors, including interest rates, foreign exchange rates, commodity prices, or equity prices. Additionally, the financial instruments subject to market risk can be classified either as held for trading purposes or held for other than trading.

We are subject to market risk primarily through the effect of changes in interest rates on our portfolio of assets held for purposes other than trading. Additionally, we have some market risk relative to commodity prices through our energy lending activities. Petroleum and natural gas commodity prices declined substantially during the fourth quarter of 2014 and into the first quarter of 2015. Such declines in commodity prices, if sustained or continued, could negatively impact our energy clients' ability to perform on their loan obligations. Management does not currently expect the current decline in commodity prices to have a material adverse effect on our financial position. Foreign exchange rates, commodity prices and/or equity prices do not pose significant market risk to us.

The responsibility for managing market risk rests with the Balance Sheet Management Committee (“BSMC”), which operates under policy guidelines established by our board of directors. The negative acceptable variation in net interest revenue due to a 200 basis point increase or decrease in interest rates is generally limited by these guidelines to +/- 5%. These guidelines also establish maximum levels for short-term borrowings, short-term assets and public and brokered deposits. They also establish minimum levels for unpledged assets, among other things. Compliance with these guidelines is the ongoing responsibility of the BSMC, with exceptions reported to our board of directors on a quarterly basis. Additionally, the Credit Policy Committee ("CPC") specifically manages risk relative to commodity price market risks. They establish maximum portfolio concentration levels for energy loans as well as maximum advance rates for energy collateral.

Interest Rate Risk Management

Our interest rate sensitivity is illustrated in the following table. The table reflects rate-sensitive positions as of December 31, 2014, and is not necessarily indicative of positions on other dates. The balances of interest rate sensitive assets and liabilities are presented in the periods in which they next reprice to market rates or mature and are aggregated to show the interest rate sensitivity gap. The mismatch between repricings or maturities within a time period is commonly referred to as the “gap” for that period. A positive gap (asset sensitive), where interest rate-sensitive assets exceed interest rate sensitive liabilities, generally will result in the net interest margin increasing in a rising rate environment and decreasing in a falling rate environment. A negative gap (liability sensitive) will generally have the opposite results on the net interest margin. To reflect anticipated prepayments, certain asset and liability categories are shown in the table using estimated cash flows rather than contractual cash flows. The Company employs interest rate floors in certain variable rate loans to enhance the yield on those loans at times when market interest rates are extraordinarily low. The degree of asset sensitivity, spreads on loans and net interest margin may be reduced until rates increase by an amount sufficient to eliminate the effects of floors. The adverse effect of floors as market rates increase may also be offset by the positive gap, the extent to which rates on deposits and other funding sources lag increasing market rates and changes in composition of funding.

(2) Loans are stated at gross.

The table above sets forth the balances as of December 31, 2014 for interest-bearing assets, interest-bearing liabilities, and the total of non-interest-bearing deposits and stockholders’ equity. While a gap interest table is useful in analyzing interest rate sensitivity, an interest rate sensitivity simulation provides a better illustration of the sensitivity of earnings to changes in interest rates. Earnings are also affected by the effects of changing interest rates on the value of funding derived from demand deposits and stockholders’ equity. We perform a sensitivity analysis to identify interest rate risk exposure on net interest income. We quantify and measure interest rate risk exposure using a model to dynamically simulate the effect of changes in net interest income relative to changes in interest rates and account balances over the next twelve months based on three interest rate scenarios. These are a “most likely” rate scenario and two “shock test” scenarios.

The “most likely” rate scenario is based on the consensus forecast of future interest rates published by independent sources. These forecasts incorporate future spot rates and relevant spreads of instruments that are actively traded in the open market. The Federal Reserve’s Federal Funds target affects short-term borrowing; the prime lending rate and the LIBOR are the basis for most of our variable-rate loan pricing. The 10-year mortgage rate is also monitored because of its effect on prepayment speeds for mortgage-backed securities. These are our primary interest rate exposures. We are currently not using derivatives to manage our interest rate exposure.

The two “shock test” scenarios assume a sustained parallel 100 and 200 basis point increase in interest rates. As short-term rates have remained low through 2014, we do not believe that analysis of an assumed decrease in interest rates would provide meaningful results. We will continue to evaluate these scenarios as interest rates change, until short-term rates rise above 3.0%, at which point we will resume evaluations of shock scenarios in which interest rates decrease.

54

Our interest rate risk exposure model incorporates assumptions regarding the level of interest rate or balance changes on indeterminable maturity deposits (demand deposits, interest-bearing transaction accounts and savings accounts) for a given level of market rate changes. These assumptions have been developed through a combination of historical analysis and future expected pricing behavior. Changes in prepayment behavior of mortgage-backed securities, residential and commercial mortgage loans in each rate environment are captured using industry estimates of prepayment speeds for various coupon segments of the portfolio. The impact of planned growth and new business activities is factored into the simulation model. This modeling indicated interest rate sensitivity as follows (in thousands):

	Anticipated Impact Over the Next Twelve Months as Compared to Most Likely Scenario
	December 31, 2014				December 31, 2013
	100 bp Increase		200 bp Increase		100 bp Increase		200 bp Increase
Change in net interest income	$	61,615	$	133,822	$	45,847	$	103,950

The simulations used to manage market risk are based on numerous assumptions regarding the effect of changes in interest rates on the timing and extent of repricing characteristics, future cash flows and customer behavior. These assumptions are inherently uncertain and, as a result, the model cannot precisely estimate net interest income or precisely predict the impact of higher or lower interest rates on net interest income. Actual results will differ from simulated results due to timing, magnitude and frequency of interest rate changes as well as changes in market conditions and management strategies, among other factors.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders of

Texas Capital Bancshares, Inc.

We have audited the accompanying consolidated balance sheets of Texas Capital Bancshares, Inc. as of December 31, 2014 and 2013, and the related consolidated statements of income and comprehensive income, stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2014.  These financial statements are the responsibility of the Company's management.  Our responsibility is to express an opinion on these 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 financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Texas Capital Bancshares, Inc. at December 31, 2014 and 2013, and the consolidated results of their operations and their cash flows for each of the three years in the period ended December 31, 2014, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Texas Capital Bancshares, Inc.’s internal control over financial reporting as of December 31, 2014, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 19, 2015 expressed an unqualified opinion thereon.

(1) Operations and Summary of Significant Accounting Policies

Organization and Nature of Business

Texas Capital Bancshares, Inc. (the "Company”), a Delaware corporation, was incorporated in November 1996 and commenced banking operations in December 1998. The consolidated financial statements of the Company include the accounts of Texas Capital Bancshares, Inc. and its wholly owned subsidiary, Texas Capital Bank, National Association (the "Bank”). We serve the needs of commercial businesses and successful professionals and entrepreneurs located in Texas as well as operate several lines of business serving a regional or national clientele of commercial borrowers. We are primarily a secured lender, with our greatest concentration of loans in Texas.

Basis of Presentation

Our accounting and reporting policies conform to accounting principles generally accepted in the United States ("GAAP") and to generally accepted practices within the banking industry. Certain prior period balances have been reclassified to conform to the current period presentation.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The allowance for loan losses, the fair value of stock-based compensation awards, the fair values of financial instruments and the status of contingencies are particularly susceptible to significant change in the near term.

Cash and Cash Equivalents

Cash equivalents include amounts due from banks, interest-bearing deposits and Federal funds sold.

Securities

Securities are classified as trading, available-for-sale or held-to-maturity. Management classifies securities at the time of purchase and re-assesses such designation at each balance sheet date; however, transfers between categories from this re-assessment are rare.

Trading Account

Securities acquired for resale in anticipation of short-term market movements are classified as trading, with realized and unrealized gains and losses recognized in income. To date, we have not had any activity in our trading account.

Held-to-Maturity and Available-for-Sale

Debt securities are classified as held-to-maturity when we have the positive intent and ability to hold the securities to maturity. Held-to-maturity securities are stated at amortized cost. Debt securities not classified as held-to-maturity or trading and marketable equity securities not classified as trading are classified as available-for-sale.

Available-for-sale securities are stated at fair value, with the unrealized gains and losses reported in a separate component of accumulated other comprehensive income (loss), net of tax. The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity, or in the case of mortgage-backed securities, over the estimated life of the security. Such amortization and accretion is included in interest income from securities. Realized gains and losses and declines in value judged to be other-than-temporary are included in gain (loss) on sale of securities. The cost of securities sold is based on the specific identification method.

All securities are available-for-sale as of December 31, 2014 and 2013.

Loans

Loans Held for Investment

Loans held for investment (which include equipment leases accounted for as financing leases) are stated at the amount of unpaid principal reduced by deferred income (net of costs). Interest on loans is recognized using the simple-interest method on the daily balances of the principal amounts outstanding. Loan origination fees, net of direct loan origination costs, and commitment fees, are deferred and amortized as an adjustment to yield over the life of the loan, or over the commitment period, as applicable.

A loan held for investment is considered impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due (both principal and interest) according to the terms of the loan agreement. Reserves on impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest

62

rate or the fair value of the underlying collateral. Impaired loans, or portions thereof, are charged off when deemed uncollectable.

The accrual of interest on loans is discontinued when there is a clear indication that the borrower’s cash flow may not be sufficient to meet payments as they become due, which is generally when a loan is 90 days past due. When a loan is placed on non-accrual status, all previously accrued and unpaid interest is reversed. Interest income is subsequently recognized on a cash basis as long as the remaining book balance of the asset is deemed to be collectible. If collectability is questionable, then cash payments are applied to principal. A loan is placed back on accrual status when both principal and interest are current and it is probable that we will be able to collect all amounts due (both principal and interest) according to the terms of the loan agreement.

Loans held for investment includes legal ownership interests in mortgage loans that we purchase through our mortgage warehouse lending division. The ownership interests are purchased from unaffiliated mortgage originators who are seeking additional funding through sale of the undivided ownership interests to facilitate their ability to originate loans. The mortgage originator has no obligation to offer and we have no obligation to purchase these interests. The originator closes mortgage loans consistent with underwriting standards established by approved investors, and, at the time of the sale to the investor, our ownership interest and that of the originator are delivered by us to the investor selected by the originator and approved by us. We typically purchase up to a 99% ownership interest in each mortgage with the originator owning the remaining percentage. These mortgage ownership interests are held by us for a period of less than 30 days and more typically 10-20 days. Because of conditions in agreements with originators designed to reduce transaction risks, under Accounting Standards Codification 860, Transfers and Servicing of Financial Assets (“ASC 860”), the ownership interests do not qualify as participating interests. Under ASC 860, the ownership interests are deemed to be loans to the originators and payments we receive from investors are deemed to be payments made by or on behalf of the originator to repay the loan deemed made to the originator. Because we have an actual, legal ownership interest in the underlying residential mortgage loan, these interests are not extensions of credit to the originators that are secured by the mortgage loans as collateral.

Due to market conditions or events of default by the investor or the originator, we could be required to purchase the remaining interests in the mortgage loans and hold them beyond the expected 10-20 days. Mortgage loans acquired under these conditions would require mark-to-market adjustments to income and could require future allocations of the allowance for loan losses or be subject to charge off in the event the loans become impaired. Mortgage loan interests purchased and disposed of as expected receive no allocation of the allowance for loan losses due to the minimal loss experience with these assets.

Allowance for Loan Losses

The allowance for loan losses is established through a provision for loan losses charged against income. The allowance for loan losses includes specific reserves for impaired loans and a general reserve for estimated losses inherent in the loan portfolio at the balance sheet date, but not yet identified with specific loans. Loans deemed to be uncollectable are charged against the allowance when management believes that the collectability of the principal is unlikely and subsequent recoveries, if any, are credited to the allowance. Management’s periodic evaluation of the adequacy of the allowance is based on an assessment of the current loan portfolio, including known inherent risks, adverse situations that may affect the borrowers’ ability to repay, the estimated value of any underlying collateral and current economic conditions.

Other Real Estate Owned

Other real estate owned (“OREO”), which is included in other assets on the consolidated balance sheet, consists of real estate that has been foreclosed. Real estate that has been foreclosed is recorded at the fair value of the real estate, less selling costs, through a charge to the allowance for loan losses, if necessary. Subsequent write-downs required for declines in value are recorded through a valuation allowance, or taken directly to the asset, charged to other non-interest expense.

Premises and Equipment

Premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which range from three to ten years. Gains or losses on disposals of premises and equipment are included in results of operations.

Marketing and Software

Marketing costs are expensed as incurred. Ongoing maintenance and enhancements of websites are expensed as incurred. Costs incurred in connection with development or purchase of internal use software are capitalized and amortized over a period not to exceed five years. Internal use software costs are included in other assets in the consolidated balance sheets.

Goodwill and Other Intangible Assets

Intangible assets are acquired assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights or because the asset is capable of being sold or exchanged either on its own or in combination with a

63

related contract, asset, or liability. Our intangible assets relate primarily to loan customer relationships. Intangible assets with definite useful lives are amortized on an accelerated basis over their estimated life. Goodwill and intangible assets are tested for impairment annually or whenever events or changes in circumstances indicate the carrying amount of the assets may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value.

Segment Reporting

We have determined that all of our lending divisions and subsidiaries meet the aggregation criteria of ASC 280, Segment Reporting, since all offer similar products and services, operate with similar processes, and have similar customers.

Stock-based Compensation

We account for all stock-based compensation transactions in accordance with ASC 718, Compensation — Stock Compensation (“ASC 718”), which requires that stock compensation transactions be recognized as compensation expense in the consolidated statement of income and other comprehensive income based on their fair values on the measurement date, which is the date of the grant.

Accumulated Other Comprehensive Income

Unrealized gains or losses on our available-for-sale securities (after applicable income tax expense or benefit) are included in accumulated other comprehensive income, net. Accumulated comprehensive income (loss), net for the three years ended December 31, 2014 is reported in the accompanying consolidated statements of stockholders’ equity and consolidated statements of income and other comprehensive income.

Income Taxes

The Company and its subsidiary file a consolidated federal income tax return. We utilize the liability method in accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based upon the difference between the values of the assets and liabilities as reflected in the financial statements and their related tax basis using enacted tax rates in effect for the year in which the differences are expected to be recovered or settled. As changes in tax law or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. A valuation reserve is provided against deferred tax assets unless it is more likely than not that such deferred tax assets will be realized.

Basic and Diluted Earnings Per Common Share

Basic earnings per common share is based on net income available to common stockholders divided by the weighted-average number of common shares outstanding during the period excluding non-vested stock. Diluted earnings per common share include the dilutive effect of stock options and non-vested stock awards granted using the treasury stock method. A reconciliation of the weighted-average shares used in calculating basic earnings per common share and the weighted average common shares used in calculating diluted earnings per common share for the reported periods is provided in Note 14 — Earnings Per Share.

Fair Values of Financial Instruments

ASC 820, Fair Value Measurements and Disclosures (“ASC 820”), defines fair value, establishes a framework for measuring fair value under GAAP and enhances disclosures about fair value measurements. In general, fair values of financial instruments are based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows.

(1) Actual maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without prepayment penalties. The average expected life of the mortgage-backed securities was 1.2 years at December 31, 2014 and 1.4 years at December 31, 2013.

(2) Yields have been adjusted to a tax equivalent basis assuming a 35% federal tax rate.

(3) Yields are calculated based on amortized cost.

(4) These equity securities do not have a stated maturity.

Securities with carrying values of approximately $32,718,000 and $45,993,000 were pledged to secure certain borrowings and deposits at December 31, 2014 and 2013, respectively. See Note 8 — Borrowing Arrangements for discussion of securities securing borrowings. Of the pledged securities at December 31, 2014 and 2013, approximately $10,891,000 and $8,273,000, respectively, were pledged for certain deposits.

The following table discloses, as of December 31, 2014 and December 31, 2013, our investment securities that have been in a continuous unrealized loss position for less than 12 months and those that have been in a continuous unrealized loss position for 12 or more months (in thousands):

At December 31, 2014 and 2013, we had one investment with an unrealized loss position. This security is a publicly traded equity fund and is subject to market pricing volatility. We do not believe that this unrealized loss is “other than temporary.” We have evaluated the near-term prospects of the investment in relation to the severity and duration of the impairment and based on that evaluation have the ability and intent to hold the investment until recovery of fair value. We have not identified any issues related to the ultimate recovery of our investment as a result of credit concerns on this security.

Unrealized gains or losses on our available-for-sale securities (after applicable income tax expense or benefit) are included in accumulated other comprehensive income, net. We had comprehensive income of $136.0 million for the year ended

66

December 31, 2014 and comprehensive income of $119.4 million for the year ended December 31, 2013. Comprehensive income during the years ended December 31, 2014 and 2013 included a net after-tax loss of $339.0 thousand and $1.6 million, respectively, due to changes in the net unrealized gains/losses on securities available-for-sale.

Commercial Loans and Leases.    Our commercial loan portfolio is comprised of lines of credit for working capital and term loans and leases to finance equipment and other business assets. Our energy production loans are generally collateralized with proven reserves based on appropriate valuation standards and take into account the risk of oil and gas price volatility. Our commercial loans and leases are underwritten after carefully evaluating and understanding the borrower’s ability to operate profitably. Our underwriting standards are designed to promote relationship banking rather than to make loans on a transaction basis. Our lines of credit typically are limited to a percentage of the value of the assets securing the line. Lines of credit and term loans typically are reviewed annually and are supported by accounts receivable, inventory, equipment and other assets of our clients’ businesses.

Mortgage finance loans.    Our mortgage finance loans consist of ownership interests purchased in single-family residential mortgages funded through our mortgage finance group. These loans are typically on our balance sheet for 10 to 20 days. We have agreements with mortgage lenders and purchase interests in individual loans they originate. All loans are underwritten consistent with established programs for permanent financing with financially sound investors. Substantially all loans are conforming loans. December 31, 2014 and 2013 balances are stated net of $358.3 million and $33.1 million participations sold, respectively.

Construction Loans.    Our construction loan portfolio consists primarily of single- and multi-family residential properties and commercial projects used in manufacturing, warehousing, service or retail businesses. Our construction loans generally have terms of one to three years. We typically make construction loans to developers, builders and contractors that have an established record of successful project completion and loan repayment and have a substantial equity investment in the borrowers. Loan amounts are derived primarily from the bank's evaluation of expected cash flows available to service debt from stabilized projects under hypothetically stressed conditions. Construction loans are also based in part upon estimates of costs and value associated with the completed project. Sources of repayment for these types of loans may be pre-committed permanent loans from other lenders, sales of developed property, or an interim loan commitment from us until permanent financing is obtained. The nature of these loans makes ultimate repayment sensitive to overall economic conditions. Borrowers may not be able to correct conditions of default in loans, increasing risk of exposure to classification, non-performing status, reserve allocation and actual credit loss and foreclosure. These loans typically have floating rates and commitment fees.

Real Estate Loans.    A portion of our real estate loan portfolio is comprised of loans secured by properties other than market risk or investment-type real estate. Market risk loans are real estate loans where the primary source of repayment is expected to come from the sale, permanent financing or lease of the real property collateral. We generally provide temporary financing for commercial and residential property. These loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Our real estate loans generally have maximum terms of five to seven years, and we provide loans with both floating and fixed rates. We generally avoid long-term loans for commercial real estate held for investment. Real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy. Appraised values may be highly variable due to market conditions and the impact of the inability of potential purchasers and lessees to obtain financing and a lack of transactions at comparable values.

67

At December 31, 2014 and 2013, we had a blanket floating lien on certain real estate-secured loans, mortgage finance loans and also certain securities used as collateral for FHLB borrowings.

Portfolio Geographic Concentration

As of December 31, 2014, a majority of our loans held for investment, excluding our mortgage finance loans and other national lines of business, were to businesses with headquarters and operations in Texas. This geographic concentration subjects the loan portfolio to the general economic conditions within this area. Additionally, we make loans to these businesses and individuals secured by assets located outside of Texas. The risks created by the geographic distribution of loans have been considered by management in the determination of the adequacy of the allowance for loan losses. Management believes the allowance for loan losses is appropriate to cover estimated losses on loans at each balance sheet date.

Summary of Loan Losses

The allowance for loan losses is comprised of specific reserves for impaired loans and an estimate of losses inherent in the portfolio at the balance sheet date, but not yet identified with specified loans. We regularly evaluate our reserve for loan losses to maintain an appropriate level to absorb estimated loan losses inherent in the loan portfolio. Factors contributing to the determination of reserves include the creditworthiness of the borrower, changes in the value of pledged collateral, and general economic conditions. All loan commitments rated substandard or worse and greater than $500,000 are specifically reviewed for loss potential. For loans deemed to be impaired, a specific allocation is assigned based on the losses expected to be realized from those loans. For purposes of determining the general reserve, the portfolio is segregated by product types to recognize differing risk profiles among categories, and then further segregated by credit grades. Credit grades are assigned to all loans. Each credit grade is assigned a risk factor, or reserve allocation percentage. These risk factors are multiplied by the outstanding principal balance and risk-weighted by product type to calculate the required reserve. A similar process is employed to calculate a reserve assigned to off-balance sheet commitments, specifically unfunded loan commitments and letters of credit, and any needed reserve is recorded in other liabilities. Even though portions of the allowance may be allocated to specific loans, the entire allowance is available for any credit that, in management’s judgment, should be charged off.

We have several pass credit grades that are assigned to loans based on varying levels of risk, ranging from credits that are secured by cash or marketable securities, to watch credits which have all the characteristics of an acceptable credit risk but warrant more than the normal level of monitoring. Within our criticized/classified credit grades are special mention, substandard, and doubtful. Special mention loans are those that are currently protected by sound worth and paying capacity of the borrower, but that are potentially weak and constitute an additional credit risk. The loan has the potential to deteriorate to a substandard grade due to the existence of financial or administrative deficiencies. Substandard loans have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that we will sustain some loss if the deficiencies are not corrected. Some substandard loans are inappropriately protected by sound worth and paying capacity of the borrower and of the collateral pledged and may be considered impaired. Substandard loans can be accruing or can be on non-accrual depending on the circumstances of the individual loans. Loans classified as doubtful have all the weaknesses inherent in substandard loans with the added characteristics that the weaknesses make collection or liquidation in full highly questionable and improbable. The possibility of loss is extremely high. All doubtful loans are on non-accrual.

The reserve allocation percentages assigned to each credit grade have been developed based primarily on an analysis of our historical loss rates. The allocations are adjusted for certain qualitative factors, including general economic conditions, changes in credit policies and lending standards. Changes in the trend and severity of problem loans can cause the estimation of losses to differ from past experience. In addition, the reserve considers the results of reviews performed by independent third party reviewers as reflected in their confirmations of assigned credit grades within the portfolio. The portion of the allowance that is not derived by the allowance allocation percentages compensates for the uncertainty and complexity in estimating loan and lease losses including factors and conditions that may not be fully reflected in the determination and application of the allowance allocation percentages. Examples of risks that support the Bank's maintaining an unallocated reserve include the possibility of precipitous negative changes in economic conditions and borrowers' submission of financial statements or certifications of collateral value that subsequently prove to be materially inaccurate for reason of either misstatement or omission of critical information. These situations, while not common, do not necessarily correlate well with the general risk profile presented by assigned credit grade and product type categories. We evaluate many such factors and conditions in determining the unallocated portion of the allowance, including amount and frequency of losses attributable to issues not specifically addressed or included in the determination and application of the allowance allocation percentages. The allowance is considered appropriate, given management’s assessment of potential losses within the portfolio as of the evaluation date, the significant growth in the loan and lease portfolio, current economic conditions in the Company’s market areas and other factors.

The methodology used in the periodic review of reserve adequacy, which is performed at least quarterly, is designed to be dynamic and responsive to changes in portfolio credit quality. The changes are reflected in the general reserve and in specific reserves as the collectability of larger classified loans is evaluated with new information. As our portfolio has matured,

68

historical loss ratios have been closely monitored, and our reserve adequacy relies primarily on our loss history. The review of reserve adequacy is performed by executive management and presented to a committee of our board of directors for their review. The committee reports to the board as part of the board's review on a quarterly basis of the Company's consolidated financial statements.

We have traditionally maintained an unallocated reserve component to compensate for the uncertainty and complexity in estimating loan and lease losses including factors and conditions that may not be fully reflected in the determination and application of the allowance allocation percentages. We believe the level of unallocated reserves at December 31, 2014 is warranted due to the continued uncertain economic environment which has produced losses, including those resulting from borrowers' misstatement of financial information or inaccurate certification of collateral values. Such losses are not necessarily correlated with historical loss trends or general economic conditions. Our methodology used to calculate the allowance considers historical losses; however, the historical loss rates for specific product types or credit risk grades may not fully incorporate the effects of continued weakness in the economy.

Generally we place loans on non-accrual when there is a clear indication that the borrower’s cash flow may not be sufficient to meet payments as they become due, which is generally when a loan is 90 days past due. When a loan is placed on non-accrual status, all previously accrued and unpaid interest is reversed. Interest income is subsequently recognized on a cash basis as long as the remaining unpaid principal amount of the loan is deemed to be fully collectible. If collectability is questionable, then cash payments are applied to principal. We recognized $1.7 million in interest income on non-accrual loans during 2014 compared to $2.4 million in 2013 and $2.6 million in 2012. Additional interest income that would have been recorded if the loans had been current during the years ended December 31, 2014, 2013 and 2012 totaled $2.1 million, $2.5 million and $2.4 million, respectively. As of December 31, 2014, $310,000 of our non-accrual loans were earning on a cash basis, compared to none at December 31, 2013. A loan is placed back on accrual status when both principal and interest are current and it is probable that we will be able to collect all amounts due (both principal and interest) according to the terms of the loan agreement.

71

A loan held for investment is considered impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due (both principal and interest) according to the terms of the loan agreement. In accordance with FASB ASC 310 Receivables, we have included all restructured loans in our impaired loan totals. The following tables detail our impaired loans, by portfolio class as of December 31, 2014 and 2013 (in thousands):

(1) Loans past due 90 days and still accruing includes premium finance loans of $3.7 million. These loans are generally secured by obligations of insurance carriers to refund premiums on cancelled insurance policies. The refund of premiums from the insurance carriers can take 180 days or longer from the cancellation date.

Restructured loans are loans on which, due to the borrower’s financial difficulties, we have granted a concession that we would not otherwise consider for borrowers of similar credit quality. This may include a transfer of real estate or other assets from the borrower, a modification of loan terms, or a combination of the two. Modifications of terms that could potentially qualify as a restructuring include reduction of contractual interest rate, extension of the maturity date at a contractual interest rate lower than the current rate for new debt with similar risk, or a reduction of the face amount of debt, or forgiveness of either principal or accrued interest. As of December 31, 2014 and December 31, 2013, we had $1.8 million and $1.9 million, respectively, in loans considered restructured that are not on non-accrual. These loans did not have unfunded commitments at December 31, 2014 or 2013. Of the non-accrual loans at December 31, 2014 and 2013, $12.1 million and $17.8 million, respectively, met the criteria for restructured. These loans had no unfunded commitments at their respective balance sheet dates. A loan continues to qualify as restructured until a consistent payment history or change in borrower’s financial condition has been evidenced, generally no less than twelve months. Assuming that the restructuring agreement specifies an interest rate at the time of the restructuring that is greater than or equal to the rate that we are willing to accept for a new extension of credit with comparable risk, then the loan no longer has to be considered a restructuring if it is in compliance with modified terms in calendar years after the year of the restructure.

The following tables summarize, as of December 31, 2014 and 2013, loans that have been restructured during 2014 and 2013 (in thousands):

December 31, 2014
	Number of Contracts	Pre-Restructuring Outstanding Recorded Investment		Post-Restructuring Outstanding  Recorded Investment
Real estate - commercial	1	$	1,441	$	1,441
Commercial business loans	1	$	95	$	80
Total new restructured loans in 2014	2	$	1,536	$	1,521

Real estate market risk	1	892		874
Total new restructured loans in 2013	4	$	11,715	$	9,795

The restructured loans generally include terms to temporarily place the loan on interest only, extend the payment terms or reduce the interest rate. We did not forgive any principal on the above loans. The $15,000 decrease in the post-restructuring recorded investment compared to the pre-restructuring recorded investment is due to paydowns. At December 31, 2014, $1.5 million of the above loans restructured in 2014 are on non-accrual. The restructuring of the loans did not have a significant impact on our allowance for loan losses at December 31, 2014 or 2013.

The following table provides information on how loans were modified as a restructured loan during the year ended December 31, 2014 and 2013 (in thousands):

(5) Goodwill and Other Intangible Assets

In May 2013, we acquired the assets of a premium finance company and recorded a total intangible asset of $2.1 million. Of this total, $954,000 was allocated to goodwill, $554,000 to customer relationships, $457,000 to developed technology and $98,000 to trade name. The $554,000 customer relationship intangible will be amortized over 14 years, the $457,000 technology intangible will be amortized over 7 years, and the $98,000 intangible related to the trade name was determined to have an indefinite life.

We had an existing non-revolving amortizing line of credit with $100.0 million of unused capacity that matured on December 15, 2014. This line of credit was renewed on December 23, 2014 with a new maturity date of December 22, 2015. The loan proceeds may be used for general corporate purposes including funding regulatory capital infusions into the Bank. The loan agreement contains customary financial covenants and restrictions. As of December 31, 2014, no borrowings were outstanding compared to $15.0 million outstanding at December 31, 2013.

The scheduled maturities of our borrowings at December 31, 2014, were as follows (in thousands):

(9) Long-Term Debt

From November 2002 to September 2006 various Texas Capital Statutory Trusts were created and subsequently issued floating rate trust preferred securities in various private offerings totaling $113.4 million. As of December 31, 2014, the details of the trust preferred subordinated debentures are summarized below (in thousands):

	Texas Capital Bancshares Statutory Trust I	Texas Capital Statutory Trust II	Texas Capital Statutory Trust III	Texas Capital Statutory Trust IV	Texas Capital Statutory Trust V
Date issued	November 19, 2002	April 10, 2003	October 6, 2005	April 28, 2006	September 29, 2006
Trust preferred securities issued	$10,310	$10,310	$25,774	$25,774	$41,238

Interest rate on subordinated debentures	3 month LIBOR  + 3.35%	3 month LIBOR  + 3.25%	3 month LIBOR  + 1.51%	3 month LIBOR  + 1.60%	3 month LIBOR  + 1.71%
Maturity date	November 2032	April 2033	December 2035	June 2036	December 2036

On September 21, 2012, we issued $111.0 million of subordinated notes. The notes mature in September 2042 and bear interest at a rate of 6.50% per annum, payable quarterly. The indenture governing the notes contains customary covenants and restrictions.

On January 31, 2014, the Bank issued $175.0 million of subordinated notes in an offering to institutional investors exempt from registration under Section 3(a)(2) of the Securities Act of 1933 and 12 C.F.R. Part 16. Net proceeds from the transaction were $172.4 million. The notes mature in January 2026 and bear interest at a rate of 5.25% per annum, payable semi-annually. The notes are unsecured and are subordinate to the Bank’s obligations to its depositors, its obligations under banker’s acceptances and letters of credit, certain obligations to Federal Reserve Banks and the FDIC and the Bank’s obligations to its other creditors, except any obligations which expressly rank on a parity with or junior to the notes. The notes qualify as Tier 2 capital for regulatory capital purposes, subject to applicable limitations.

Interest payments on all long-term debt are deductible for federal income tax purposes.

Because our bank had less than $15.0 billion in total consolidated assets as of December 31, 2009, we are allowed to continue to classify our trust preferred securities, all of which were issued prior to May 19, 2010, as Tier 1 capital.

(10) Income Taxes

We have a gross deferred tax asset of $65.5 million and $60.2 million at December 31, 2014 and 2013, respectively, which relates primarily to our allowance for loan losses, loan origination fees and stock compensation. Management believes it is more likely than not that all of the deferred tax assets will be realized. Our net deferred tax asset is included in other assets in the consolidated balance sheet.

Income tax expense/(benefit) consists of the following for the years ended (in thousands):

ASC 740-10, Income Taxes — Accounting for Uncertainties in Income Taxes (“ASC 740-10”) prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. Benefits from tax positions should be recognized in the financial statements only when it is more likely than not that the tax position will be sustained upon examination by the appropriate taxing authority that would have full knowledge of all relevant information. A tax position that meets the more-likely-than-not recognition threshold is measured at the largest amount of cumulative benefit that is greater than fifty percent likely of being realized upon ultimate settlement. Tax positions that previously failed to meet the more-likely-than-not recognition threshold should be recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not recognition threshold should be derecognized in the first subsequent financial reporting period in which that threshold is no longer met. ASC 740-10 also provides guidance on the accounting for and disclosure of unrecognized tax benefits, interest and penalties.

We file income tax returns in the U.S. federal jurisdiction and several U.S. state jurisdictions. We are no longer subject to U.S. federal income tax examinations by tax authorities for years before 2011.

The reconciliation of income computed at the U.S. federal statutory tax rates to income tax expense (benefit) is as follows:

	Year ended December 31,
	2014		2013		2012
Tax at U.S. statutory rate	35	%	35	%	35	%
State taxes	1	%	1	%	1	%
Non-deductible expenses	1	%	1	%	1	%
Non-taxable income	(1	)%	(1	)%	(1	)%
Total	36	%	36	%	36	%

(11) Employee Benefits

We have a qualified retirement plan, with a salary deferral feature designed to qualify under Section 401 of the Internal Revenue Code (“the 401(k) Plan”). The 401(k) Plan permits our employees to defer a portion of their compensation. Matching contributions may be made in amounts and at times determined by the Company. We contributed approximately $4.5 million, $3.7 million, and $2.7 million for the years ended December 31, 2014, 2013 and 2012, respectively. Employees are eligible to participate in the 401(k) Plan when they meet certain requirements concerning minimum age and period of credited service. All contributions to the 401(k) Plan are invested in accordance with participant elections among certain investment options.

During 2000, we implemented an Employee Stock Purchase Plan (“ESPP”). Employees are eligible for the plan when they have met certain requirements concerning period of credited service and minimum hours worked. Eligible employees may contribute a minimum of 1% to a maximum of 10% of eligible compensation up to the Section 423 of the Internal Revenue Code limit of $25,000. In 2006, stockholders approved the 2006 ESPP, which allocated 400,000 shares for purchase. As of December 31, 2014, 2013 and 2012, 102,836, 93,388 and 85,013 shares had been purchased on behalf of the employees under the 2006 ESPP.

As of December 31, 2014, we had three equity-based compensation plans, the 1999 Stock Omnibus Plan (“1999 Plan”), the 2005 Long-Term Incentive Plan (“2005 Plan”) and the 2010 Long-Term Incentive Plan (“2010 Plan”). The 1999 Plan is no longer available for grants of equity based compensation; however, options to purchase shares previously issued under the plan will remain outstanding and be subject to administration by the Human Resources Committee of our board of directors. Under both the 2005 and 2010 Plans, equity-based compensation grants were made by the board of directors, or its designated committee. Grants are subject to vesting requirements. Under the 2005 and 2010 Plans, we may grant, among other things, nonqualified stock options, incentive stock options, restricted stock units (“RSUs”), stock appreciation rights (“SARs”), cash-based performance units or any combination thereof. Both Plans include grants for employees and directors. Total shares authorized under the 2005 plan are 1,500,000, with 700,000 authorized under the 2010 Plan. Total shares which may be issued under the 2005 Plan at December 31, 2014, 2013 and 2012 were 44,655, 43,495 and 26,615, respectively. Total shares which may be issued under the 2010 Plan at December 31, 2014, 2013 and 2012 were 180,120, 218,820 and 363,020, respectively.

The fair value of our stock option and SAR grants are estimated at the date of grant using the Black-Scholes option pricing model. The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options which have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions including the expected stock price volatility. Because our employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management’s opinion, the existing models do not necessarily provide the best single measure of the fair value of its employee stock options.

80

The fair value of the options and stock appreciation rights were estimated at the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions:

	2014		2013		2012
Risk-free rate	1.46	%	1.17	%	0.76	%
Market price volatility factor	0.402		0.409		0.404
Weighted-average expected life of options	5 years		5 years		5 years

Market price volatility and expected life of options is based on historical data and other factors.

A summary of our stock option activity and related information for 2014, 2013 and 2012 is as follows:

There was no expense related to stock option awards in 2014, 2013 and 2012. No stock options were granted in 2014, 2013 or 2012.

Pursuant to the 2010 Long-term Incentive Plan, we granted stock appreciation rights in 2014, 2013 and 2012. These rights are time-vested and generally vest ratably over a period of five years.

As of December 31, 2014, 2013 and 2012, the intrinsic value of SARs vested was $11.8 million, $16.0 million and $10.9 million, respectively.

The following table summarizes the status of and changes in our nonvested restricted stock units:

Forfeited	(17,375	)	37.40
Balance, December 31, 2014	289,165		$	42.93

The RSUs granted during 2014, 2013 and 2012 vest ratably over four to five years. Compensation cost for restricted stock units was $4,098,000, $3,551,000, $4,875,000 for years ended December 31, 2014, 2013 and 2012, respectively. The weighted average remaining contractual life of RSUs currently outstanding is 8.11 years.

Total compensation cost for all share-based arrangements, net of taxes, was $3,008,000, $2,677,000 and $3,626,000 for the years ended December 31, 2014, 2013 and 2012, respectively.

Unrecognized stock-based compensation expense related to SAR grants issued through December 31, 2014 was $1.1 million. At December 31, 2014, the weighted average period over which this unrecognized expense was expected to be recognized was 3.2 years. Unrecognized stock-based compensation expense related to RSU grants through December 31, 2014 was $10.6

82

million. At December 31, 2014, the weighted average period over which this unrecognized expense was expected to be recognized was 3.5 years.

Cash flows from financing activities included $2,929,000, $1,200,000 and $7,769,000 in cash inflows from excess tax benefits related to stock compensation in 2014, 2013 and 2012, respectively.

Upon share option exercise, new shares are issued as opposed to treasury shares.

Pursuant to the 2010 Long-term Incentive Plan, we granted a total of 171,808, 173,035 and 344,127 cash-based performance units in 2014, 2013 and 2012, with a total of 502,532 outstanding at December 31, 2014. Of the outstanding units at December 31, 2014, 328,916 are service-based and vest ratably over a period of five years. Additionally, 173,616 units contain both service and performance based vesting requirements: 25-50% of the units will vest on the third anniversary of the date of grant, and the balance will vest based on attainment of certain performance metrics developed by the Human Resources Committee. Since these units have a cash payout feature, they are accounted for under the liability method and the related expense is based on the stock price at period end. Compensation cost for the units was $9,949,000, $17,287,000 and $6,440,000 for the years ended December 31, 2014, 2013, and 2012 respectively. At December 31, 2014, the weighted average remaining contractual life of the units was 8.08 years.

Total compensation cost for all cash-based arrangements, net of taxes, for the years ended December 31, 2014, 2013 and 2012 was $6,467,000, $11,237,000 and $4,186,000, respectively.

(12) Financial Instruments with Off-Balance Sheet Risk

The Bank is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit that involve varying degrees of credit risk in excess of the amount recognized in the consolidated balance sheets. The Bank’s exposure to credit loss in the event of non-performance 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 Bank uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. The amount of collateral obtained, if deemed necessary, is based on management’s credit evaluation of the borrower.

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 generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Bank evaluates each customer’s credit-worthiness on a case-by-case basis.

Standby letters of credit are conditional commitments issued by the Bank to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.

At December 31, 2014 and 2013, commitments to extend credit and standby and commercial letters of credit were as follows (in thousands):

	December 31,
	2014		2013
Commitments to extend credit	$	5,324,460	$	3,674,391
Standby letters of credit	177,808		145,662

At December 31, 2014 and 2013, we had $7.1 million and $4.7 million, respectively, in allowance allocations for these off-balance sheet commitments.

(13) Regulatory Restrictions

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

In July 2013, the Federal Reserve published final rules for the adoption of the Basel III regulatory capital framework (the "Basel III Capital Rules"). The Basel III Capital Rules, among other things, (i) introduce a new capital measure called "Common Equity Tier 1," (ii) specify that Tier 1 capital consist of Common Equity Tier 1 and "Additional Tier 1 Capital"

83

instruments meeting specified requirements, (iii) define Common Equity Tier 1 narrowly by requiring that most deductions/adjustments to regulatory capital measures be made to Common Equity Tier 1 and not to the other components of capital and (iv) expand the scope of the deductions/adjustments as compared to existing regulations. The Basel III Capital Rules became effective for us on January 1, 2015 with certain transition provisions fully phased in on January 1, 2019. Based on our initial assessment of the Basel III Capital Rules, we do not believe they will have a material impact on the Company or our bank. We believe we will meet the capital adequacy requirements under the Basel III Capital Rules on a fully phased-in basis when we commence filing 2015 reports with the FDIC and OCC.

Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios of total and Tier 1 capital to risk-weighted assets, and of Tier 1 capital to average assets, each as defined in the regulations. Management believes, as of December 31, 2014, that the Company and the Bank meet all capital adequacy requirements to which they are subject.

Financial institutions are categorized as well capitalized or adequately capitalized, based on minimum total risk-based, Tier 1 risk-based and Tier 1 leverage ratios. As shown in the table below, the Company’s capital ratios exceeded the regulatory definition of adequately capitalized as of December 31, 2014 and 2013. Based upon the information in its most recently filed call report, the Bank met the capital ratios necessary to be well capitalized. The regulatory authorities can apply changes in classification of assets and such change may retroactively subject the Company to change in capital ratios. Any such change could result in reducing one or more capital ratios below well-capitalized status. In addition, a change may result in imposition of additional assessments by the FDIC or could result in regulatory actions that could have a material effect on condition and results of operations.

Because our bank had less than $15.0 billion in total consolidated assets as of December 31, 2009, we are allowed to continue to classify our trust preferred securities, all of which were issued prior to May 19, 2010, as Tier 1 capital.

The table below summarizes our capital ratios:

	Actual				For Capital Adequacy Purposes				To Be Well Capitalized Under Prompt Corrective Action Provisions
(Dollars in thousands)	Amount		Ratio		Amount		Ratio		Amount		Ratio
As of December 31, 2014:

Dividends that may be paid by subsidiary banks are routinely restricted by various regulatory authorities. The amount that can be paid in any calendar year without prior approval of the Bank’s regulatory agencies cannot exceed the lesser of net profits (as defined) for that year plus the net profits for the preceding two calendar years, or retained earnings. The Basel III Capital Rules,

84

will further limit the amount of dividends that be paid by our bank. No dividends were declared or paid on our common stock during 2014, 2013 or 2012.

The required reserve balances at the Federal Reserve at December 31, 2014 and 2013 were approximately $88,155,000 and $51,692,000, respectively.

(14) Earnings Per Share

(1) Stock options, SARs and RSUs outstanding of 51,300, 118,500 and 79,500 in 2014, 2013 and 2012, respectively, have not been included in diluted earnings per share because to do so would have been antidilutive for the periods presented. Stock options are antidilutive when the exercise price is higher than the average market price of the Company’s common stock.

(15) Fair Value Disclosures

ASC 820, Fair Value Measurements and Disclosures (“ASC 820”), defines fair value, establishes a framework for measuring fair value under GAAP and requires enhanced disclosures about fair value measurements. Fair value is defined under ASC 820 as the price that would be received for an asset or paid to transfer a liability (an exit price) in the principal market for the asset or liability in an orderly transaction between market participants on the measurement date.

We determine the fair market values of our assets and liabilities measured at fair value on a recurring and nonrecurring basis using the fair value hierarchy as prescribed in ASC 820. The standard describes three levels of inputs that may be used to measure fair value as provided below.

Level 1 Quoted prices in active markets for identical assets or liabilities.

Level 2 Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 assets include U.S. government and agency mortgage-backed debt securities, municipal bonds, and Community Reinvestment Act funds. This category includes derivative assets and liabilities where values are obtained from independent pricing services.

Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair values requires significant management judgment or estimation. This category also includes impaired loans and OREO where collateral values have been based on third party appraisals; however, due to current economic conditions, comparative sales data typically used in appraisals may be unavailable or more subjective due to lack of market activity.

85

Assets and liabilities measured at fair value at December 31, 2014 and 2013 are as follows (in thousands):

(1) Securities are measured at fair value on a recurring basis, generally monthly.

(2) Equity securities consist of Community Reinvestment Act funds.

(3) Includes impaired loans that have been measured for impairment at the fair value of the loan’s collateral.

(4) OREO is transferred from loans to OREO at fair value less selling costs.

(5) Fair value of loans and OREO is measured on a nonrecurring basis, generally annually or more often as warranted by market and economic conditions

(6) Derivative assets and liabilities are measured at fair value on a recurring basis, generally quarterly.

Level 3 Valuations

Financial instruments are considered Level 3 when their values are determined using pricing models, discounted cash flow methodologies or similar techniques and at least one significant model assumption or input is unobservable. Level 3 financial instruments also include those for which the determination of fair value requires significant management judgment or estimation. Currently, we measure fair value for certain loans on a nonrecurring basis as described below.

Loans

During the years ended December 31, 2014 and 2013, certain impaired loans were reevaluated and reported at fair value through a specific valuation allowance allocation of the allowance for possible loan losses based upon the fair value of the underlying collateral. The $23.5 million total above includes impaired loans at December 31, 2014 with a carrying value of $29.2 million that were reduced by specific valuation allowance allocations totaling $5.7 million for a total reported fair value of $23.5 million based on collateral valuations utilizing Level 3 valuation inputs. The $13.5 million total above includes impaired loans at December 31, 2013 with a carrying value of $14.9 million that were reduced by specific valuation allowance allocations totaling $1.4 million for a total reported fair value of $13.5 million based on collateral valuations utilizing Level 3 valuation inputs. Fair values were based on third party appraisals.

OREO

Certain foreclosed assets, upon initial recognition, were valued based on third party appraisals. At December 31, 2014 and 2013, OREO had a carrying value of $568,000 and $5.1 million, respectively, with no specific valuation allowance. The fair value of OREO was computed based on third party appraisals, which are Level 3 valuation inputs.

86

Fair Value of Financial Instruments

Generally accepted accounting principles require disclosure of fair value information about financial instruments, whether or not recognized on the balance sheet, for which it is practical to estimate that value. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. This disclosure does not and is not intended to represent the fair value of the Company.

A summary of the carrying amounts and estimated fair values of financial instruments is as follows (in thousands):

	December 31, 2014				December 31, 2013
	Carrying Amount		Estimated Fair Value		Carrying Amount		Estimated Fair Value

Derivative liabilities	31,176		31,176		14,690		14,690

The following methods and assumptions were used by the Company in estimating its fair value disclosures for financial instruments:

Cash and cash equivalents

The carrying amounts reported in the consolidated balance sheet for cash and cash equivalents approximate their fair value, which is characterized as a Level 1 asset in the fair value hierarchy.

Securities

The fair value of investment securities is based on prices obtained from independent pricing services which are based on quoted market prices for the same or similar securities, which is characterized as a Level 2 asset in the fair value hierarchy. We have obtained documentation from the primary pricing service we use about their processes and controls over pricing. In addition, on a quarterly basis we independently verify the prices that we receive from the service provider using two additional independent pricing sources. Any significant differences are investigated and resolved.

Loans, net

Loans are characterized as Level 3 assets in the fair value hierarchy. For variable-rate loans that reprice frequently with no significant change in credit risk, fair values are generally based on carrying values. The fair value for all other loans is estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. The carrying amount of accrued interest approximates its fair value. The carrying amount of mortgage finance loans approximates fair value.

Derivatives

The estimated fair value of the interest rate swaps are obtained from independent pricing services based on quoted market prices for the same or similar derivative contracts and are characterized as a Level 2 asset in the fair value hierarchy. On a quarterly basis, we independently verify the fair value using an additional independent pricing source.

Deposits

Deposits are characterized as Level 3 liabilities in the fair value hierarchy. The carrying amounts for variable-rate money market accounts approximate their fair value. Fixed-term certificates of deposit fair values are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities.

87

Federal funds purchased, customer repurchase agreements, other borrowings, subordinated notes and trust preferred subordinated debentures

The carrying value reported in the consolidated balance sheet for Federal funds purchased, customer repurchase agreements and other short-term, floating rate borrowings approximates their fair value, which is characterized as a Level 2 asset in the fair value hierarchy. The fair value of any fixed rate short-term borrowings and trust preferred subordinated debentures are estimated using a discounted cash flow calculation that applies interest rates currently being offered on similar borrowings, which is characterized as a Level 3 liability in the fair value hierarchy. The subordinated notes are publicly traded and are valued based on market prices, which is characterized as a Level 2 liability in the fair value hierarchy.

(16) Commitments and Contingencies

We lease various premises under operating leases with various expiration dates ranging from January 2018 through February 2025. Rent expense incurred under operating leases amounted to approximately $13,639,000, $10,216,000 and $8,993,000 for the years ended December 31, 2014, 2013 and 2012, respectively.

Minimum future lease payments under operating leases are as follows (in thousands):

See Note 7 for a description of deposits from related parties.

(19) Derivative Financial Instruments

The fair value of derivative positions outstanding is included in other assets and other liabilities in the accompanying consolidated balance sheets on a net basis when a right of offset exists, based on transactions with a single counterparty that are subject to a legally enforceable master netting agreement.

During 2014 and 2013, we entered into certain interest rate derivative positions that were not designated as hedging instruments. These derivative positions relate to transactions in which we enter into an interest rate swap, cap and/or floor with a customer while at the same time entering into an offsetting interest rate swap, cap and/or floor with another financial institution. In connection with each swap transaction, we agree to pay interest to the customer on a notional amount at a variable interest rate and receive interest from the customer on a similar notional amount at a fixed interest rate. At the same time, we agree to pay another financial institution the same fixed interest rate on the same notional amount and receive the same variable interest rate on the same notional amount. The transaction allows our customer to effectively convert a variable rate loan to a fixed rate. Because we act as an intermediary for our customer, changes in the fair value of the underlying derivative contracts substantially offset each other and do not have a material impact on our results of operations.

The notional amounts and estimated fair values of interest rate derivative positions outstanding at December 31, 2014 and 2013 presented in the following table (in thousands):

Net derivatives included in the consolidated balance sheets			$	31,176		$	31,176				$	14,690		$	14,690

The weighted-average receive and pay interest rates for interest rate swaps outstanding at December 31, 2014 and 2013 were as follows:

	December 31, 2014 Weighted-Average Interest  Rate				December 31, 2013 Weighted-Average Interest  Rate
	Received		Paid		Received		Paid
Non-hedging interest rate swaps	2.79	%	4.82	%	2.99	%	4.89	%

The weighted-average strike rate for outstanding interest rate caps was 1.44% at December 31, 2014 and 1.87% at December 31, 2013.

Our credit exposure on interest rate swaps and caps is limited to the net favorable value and interest payments of all swaps and caps by each counterparty. In such cases collateral may be required from the counterparties involved if the net value of the swaps and caps exceeds a nominal amount considered to be immaterial. Our credit exposure, net of any collateral pledged, relating to interest rate swaps and caps was approximately $31.2 million at December 31, 2014 and approximately $14.7 million at December 31, 2013, all of which relates to bank customers. Collateral levels are monitored and adjusted on a regular basis for changes in interest rate swap and cap values. At December 31, 2014 and 2013, we had $30.2 million and $10.7 million in cash collateral pledged for these derivatives included in interest-bearing deposits.

(20) Stockholders’ Equity

In January 2009, we issued $75 million of perpetual preferred stock and related warrants under the U.S. Department of Treasury’s voluntary Capital Purchase Program. The preferred stock was repurchased in May 2009 and the U.S. Treasury auctioned the related warrants in the first quarter of 2010. As of December 31, 2014, warrants to purchase 581,500 shares at $14.84 per share are still outstanding.

On March 28, 2013, we completed a sale of 6.0 million shares of 6.5% non-cumulative preferred stock, par value $0.01, with a liquidation preference of $25 per share, in a public offering. Dividends on the preferred stock are not cumulative and will be paid when declared by our board of directors to the extent that we have lawfully available funds to pay dividends. If declared, dividends will accrue and be payable quarterly, in arrears, on the liquidation preference amount, on a non-cumulative basis, at a rate of 6.50% per annum. We paid $9.8 million in dividends on the preferred stock for the year ended December 31, 2014 compared to $7.0 million for the same period of 2013. Holders of preferred stock do not have voting rights, except with respect to authorizing or increasing the authorized amount of senior stock, certain changes in the terms of the preferred stock, certain dividend non-payments and as otherwise required by applicable law. Net proceeds from the sale totaled $145.0 million. The additional equity was used for general corporate purposes, including funding regulatory capital infusions into the Bank.

In January 2014, we completed an offering of 1.9 million shares of our common stock. Net proceeds from the sale totaled $106.5 million.

(22) New Accounting Standards

ASU 2014-04 “Receivables (Topic 310) - Troubled Debt Restructurings by Creditors” (“ASU 2014-04”) amends Topic 310 “Receivables” to clarify the terms defining when an in substance repossession or foreclosure occurs, which determines when the receivable should be derecognized and the real estate property is recognized. ASU 2013-04 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2014. It is not expected to have a significant impact on our consolidated financial statements.

ASU 2014-09 "Revenue from Contracts with Customers (Topic 606)" ("ASU 2014-09") implements a common revenue standard that clarifies the principles for recognizing revenue. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 establishes a five-step model which entities must follow to recognize revenue and removes inconsistencies and weaknesses in existing guidance. ASU 2014-09 is effective for annual and interim periods beginning after December 15, 2016 and is not expected to have a significant impact on our consolidated financial statements.

ASU 2014-11 "Transfers and Servicing (Topic 860" ("ASU 2014-11") requires that repurchase-to-maturity transactions be accounted for as secured borrowings consistent with the accounting for other repurchase agreements. The amendments to ASU 2014-11 update the accounting for repurchase-to-maturity transactions and link repurchase financings to secured borrowing accounting, which is consistent with the accounting for other repurchase agreements. ASU 2014-11 also requires two new disclosures. The first disclosure requires an entity to disclose information on transfers accounted for as sales that are economically similar to repurchase agreements. The second disclosure provides added transparency about the types of collateral pledged in repurchase agreements and similar transactions accounted for as secured borrowings. ASU 2014-11 is effective for annual and interim periods beginning after December 15, 2014 and is not expected to have a significant impact on our consolidated financial statements.

ASU 2014-12 "Compensation - Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period" ("ASU 2014-12") requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. ASU 2014-12 is intended to resolve the diverse accounting treatments of these types of awards in practice and is effective for annual and interim periods beginning after December 15, 2015 and is not expected to have a significant impact on our consolidated financial statements.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the supervision and participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act of 1934, as amended) as of the end of the period covered by this report. Based upon that evaluation, we have concluded that, as of the end of such period, our disclosure controls and procedures were effective in recording, processing, summarizing and reporting, on a timely basis, information required to be disclosed by us in the reports that we file or submit under the Exchange Act and were effective in ensuring that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to the Company's management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(e) and 15d-15(f) under the Exchange Act) during the period covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Management’s Report on Internal Control over Financial Reporting

The management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control over financial reporting is a process designed under the supervision of our Chief Executive Officer and Chief Financial Officer to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our financial statements for external purposes in accordance with generally accepted accounting principles.

As of December 31, 2014, management assessed the effectiveness of the Company’s internal control over financial reporting based on the criteria for effective internal control over financial reporting established in “Internal Control—Integrated Framework (2013),” issued by the Committee of Sponsoring Organizations (COSO) of the Treadway Commission. Based on the assessment, management determined that the Company maintained effective internal control over financial reporting as of December 31, 2014.

Ernst & Young LLP, the independent registered public accounting firm that audited the consolidated financial statements of the Company included in this Annual Report on Form 10-K, has issued an attestation report on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2014. The report, which expresses an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2014, is included in this Item under the heading “Report of Independent Registered Public Accounting Firm.”

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders of

Texas Capital Bancshares, Inc.

We have audited Texas Capital Bancshares, Inc.’s internal control over financial reporting as of December 31, 2014, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). Texas Capital Bancshares Inc.’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 Report 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 to provide reasonable assurance regarding the reliability of financial reporting and the preparation of 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 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 financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that 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, Texas Capital Bancshares Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2014, based onthe COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Texas Capital Bancshares, Inc. as of December 31, 2014 and 2013, and the related consolidated statements of comprehensive income, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2014 and our report dated February 19, 2015 expressed an unqualified opinion thereon.

(1) Actual maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without prepayment penalties. The average expected life of the mortgage-backed securities was 1.2 years at December 31, 2014 and 1.4 years at December 31, 2013.

(2) Yields have been adjusted to a tax equivalent basis assuming a 35% federal tax rate.

(3) Yields are calculated based on amortized cost.

(4) These equity securities do not have a stated maturity.

Securities with carrying values of approximately $32,718,000 and $45,993,000 were pledged to secure certain borrowings and deposits at December 31, 2014 and 2013, respectively. See Note 8 — Borrowing Arrangements for discussion of securities securing borrowings. Of the pledged securities at December 31, 2014 and 2013, approximately $10,891,000 and $8,273,000, respectively, were pledged for certain deposits.

The following table discloses, as of December 31, 2014 and December 31, 2013, our investment securities that have been in a continuous unrealized loss position for less than 12 months and those that have been in a continuous unrealized loss position for 12 or more months (in thousands):

December 31, 2014	Less Than 12 Months					12 Months or Longer					Total
	Fair Value		Unrealized Loss			Fair Value		Unrealized Loss			Fair Value		Unrealized Loss
Equity securities	$	—	$	—		$	6,349	$	(151	)	$	6,349	$	(151	)
December 31, 2013	Less Than 12 Months					12 Months or Longer					Total

Equity securities	$	7,247	$	(275	)	$	—	$	—		$	7,247	$	(275	)

At December 31, 2014 and 2013, we had one investment with an unrealized loss position. This security is a publicly traded equity fund and is subject to market pricing volatility. We do not believe that this unrealized loss is “other than temporary.” We have evaluated the near-term prospects of the investment in relation to the severity and duration of the impairment and based on that evaluation have the ability and intent to hold the investment until recovery of fair value. We have not identified any issues related to the ultimate recovery of our investment as a result of credit concerns on this security.

Unrealized gains or losses on our available-for-sale securities (after applicable income tax expense or benefit) are included in accumulated other comprehensive income, net. We had comprehensive income of $136.0 million for the year ended December 31, 2014 and comprehensive income of $119.4 million for the year ended December 31, 2013. Comprehensive income during the years ended December 31, 2014 and 2013 included a net after-tax loss of $339.0 thousand and $1.6 million, respectively, due to changes in the net unrealized gains/losses on securities available-for-sale.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

New Accounting Standards

New Accounting Standards

ASU 2014-04 “Receivables (Topic 310) - Troubled Debt Restructurings by Creditors” (“ASU 2014-04”) amends Topic 310 “Receivables” to clarify the terms defining when an in substance repossession or foreclosure occurs, which determines when the receivable should be derecognized and the real estate property is recognized. ASU 2013-04 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2014. It is not expected to have a significant impact on our consolidated financial statements.

ASU 2014-09 "Revenue from Contracts with Customers (Topic 606)" ("ASU 2014-09") implements a common revenue standard that clarifies the principles for recognizing revenue. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 establishes a five-step model which entities must follow to recognize revenue and removes inconsistencies and weaknesses in existing guidance. ASU 2014-09 is effective for annual and interim periods beginning after December 15, 2016 and is not expected to have a significant impact on our consolidated financial statements.

ASU 2014-11 "Transfers and Servicing (Topic 860" ("ASU 2014-11") requires that repurchase-to-maturity transactions be accounted for as secured borrowings consistent with the accounting for other repurchase agreements. The amendments to ASU 2014-11 update the accounting for repurchase-to-maturity transactions and link repurchase financings to secured borrowing accounting, which is consistent with the accounting for other repurchase agreements. ASU 2014-11 also requires two new disclosures. The first disclosure requires an entity to disclose information on transfers accounted for as sales that are economically similar to repurchase agreements. The second disclosure provides added transparency about the types of collateral pledged in repurchase agreements and similar transactions accounted for as secured borrowings. ASU 2014-11 is effective for annual and interim periods beginning after December 15, 2014 and is not expected to have a significant impact on our consolidated financial statements.

ASU 2014-12 "Compensation - Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period" ("ASU 2014-12") requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. ASU 2014-12 is intended to resolve the diverse accounting treatments of these types of awards in practice and is effective for annual and interim periods beginning after December 15, 2015 and is not expected to have a significant impact on our consolidated financial statements.

Operations and Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2014

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization and Nature of Business

Organization and Nature of Business

Texas Capital Bancshares, Inc. (the "Company”), a Delaware corporation, was incorporated in November 1996 and commenced banking operations in December 1998. The consolidated financial statements of the Company include the accounts of Texas Capital Bancshares, Inc. and its wholly owned subsidiary, Texas Capital Bank, National Association (the "Bank”). We serve the needs of commercial businesses and successful professionals and entrepreneurs located in Texas as well as operate several lines of business serving a regional or national clientele of commercial borrowers. We are primarily a secured lender, with our greatest concentration of loans in Texas.

Basis of Presentation

Basis of Presentation

Our accounting and reporting policies conform to accounting principles generally accepted in the United States ("GAAP") and to generally accepted practices within the banking industry. Certain prior period balances have been reclassified to conform to the current period presentation.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The allowance for loan losses, the fair value of stock-based compensation awards, the fair values of financial instruments and the status of contingencies are particularly susceptible to significant change in the near term.

Cash and Cash Equivalents

Cash and Cash Equivalents

Cash equivalents include amounts due from banks, interest-bearing deposits and Federal funds sold.

Securities

Securities

Securities are classified as trading, available-for-sale or held-to-maturity. Management classifies securities at the time of purchase and re-assesses such designation at each balance sheet date; however, transfers between categories from this re-assessment are rare.

Trading Account

Securities acquired for resale in anticipation of short-term market movements are classified as trading, with realized and unrealized gains and losses recognized in income. To date, we have not had any activity in our trading account.

Held-to-Maturity and Available-for-Sale

Debt securities are classified as held-to-maturity when we have the positive intent and ability to hold the securities to maturity. Held-to-maturity securities are stated at amortized cost. Debt securities not classified as held-to-maturity or trading and marketable equity securities not classified as trading are classified as available-for-sale.

Available-for-sale securities are stated at fair value, with the unrealized gains and losses reported in a separate component of accumulated other comprehensive income (loss), net of tax. The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity, or in the case of mortgage-backed securities, over the estimated life of the security. Such amortization and accretion is included in interest income from securities. Realized gains and losses and declines in value judged to be other-than-temporary are included in gain (loss) on sale of securities. The cost of securities sold is based on the specific identification method.

All securities are available-for-sale as of December 31, 2014 and 2013.

Loans

Loans

Loans Held for Investment

Loans held for investment (which include equipment leases accounted for as financing leases) are stated at the amount of unpaid principal reduced by deferred income (net of costs). Interest on loans is recognized using the simple-interest method on the daily balances of the principal amounts outstanding. Loan origination fees, net of direct loan origination costs, and commitment fees, are deferred and amortized as an adjustment to yield over the life of the loan, or over the commitment period, as applicable.

A loan held for investment is considered impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due (both principal and interest) according to the terms of the loan agreement. Reserves on impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate or the fair value of the underlying collateral. Impaired loans, or portions thereof, are charged off when deemed uncollectable.

The accrual of interest on loans is discontinued when there is a clear indication that the borrower’s cash flow may not be sufficient to meet payments as they become due, which is generally when a loan is 90 days past due. When a loan is placed on non-accrual status, all previously accrued and unpaid interest is reversed. Interest income is subsequently recognized on a cash basis as long as the remaining book balance of the asset is deemed to be collectible. If collectability is questionable, then cash payments are applied to principal. A loan is placed back on accrual status when both principal and interest are current and it is probable that we will be able to collect all amounts due (both principal and interest) according to the terms of the loan agreement.

Loans held for investment includes legal ownership interests in mortgage loans that we purchase through our mortgage warehouse lending division. The ownership interests are purchased from unaffiliated mortgage originators who are seeking additional funding through sale of the undivided ownership interests to facilitate their ability to originate loans. The mortgage originator has no obligation to offer and we have no obligation to purchase these interests. The originator closes mortgage loans consistent with underwriting standards established by approved investors, and, at the time of the sale to the investor, our ownership interest and that of the originator are delivered by us to the investor selected by the originator and approved by us. We typically purchase up to a 99% ownership interest in each mortgage with the originator owning the remaining percentage. These mortgage ownership interests are held by us for a period of less than 30 days and more typically 10-20 days. Because of conditions in agreements with originators designed to reduce transaction risks, under Accounting Standards Codification 860, Transfers and Servicing of Financial Assets (“ASC 860”), the ownership interests do not qualify as participating interests. Under ASC 860, the ownership interests are deemed to be loans to the originators and payments we receive from investors are deemed to be payments made by or on behalf of the originator to repay the loan deemed made to the originator. Because we have an actual, legal ownership interest in the underlying residential mortgage loan, these interests are not extensions of credit to the originators that are secured by the mortgage loans as collateral.

Due to market conditions or events of default by the investor or the originator, we could be required to purchase the remaining interests in the mortgage loans and hold them beyond the expected 10-20 days. Mortgage loans acquired under these conditions would require mark-to-market adjustments to income and could require future allocations of the allowance for loan losses or be subject to charge off in the event the loans become impaired. Mortgage loan interests purchased and disposed of as expected receive no allocation of the allowance for loan losses due to the minimal loss experience with these assets.

Allowance for Loan Losses

Allowance for Loan Losses

The allowance for loan losses is established through a provision for loan losses charged against income. The allowance for loan losses includes specific reserves for impaired loans and a general reserve for estimated losses inherent in the loan portfolio at the balance sheet date, but not yet identified with specific loans. Loans deemed to be uncollectable are charged against the allowance when management believes that the collectability of the principal is unlikely and subsequent recoveries, if any, are credited to the allowance. Management’s periodic evaluation of the adequacy of the allowance is based on an assessment of the current loan portfolio, including known inherent risks, adverse situations that may affect the borrowers’ ability to repay, the estimated value of any underlying collateral and current economic conditions.

Other Real Estate Owned

Other Real Estate Owned

Other real estate owned (“OREO”), which is included in other assets on the consolidated balance sheet, consists of real estate that has been foreclosed. Real estate that has been foreclosed is recorded at the fair value of the real estate, less selling costs, through a charge to the allowance for loan losses, if necessary. Subsequent write-downs required for declines in value are recorded through a valuation allowance, or taken directly to the asset, charged to other non-interest expense.

Premises and Equipment

Premises and Equipment

Premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which range from three to ten years. Gains or losses on disposals of premises and equipment are included in results of operations.

Marketing and Software

Marketing and Software

Marketing costs are expensed as incurred. Ongoing maintenance and enhancements of websites are expensed as incurred. Costs incurred in connection with development or purchase of internal use software are capitalized and amortized over a period not to exceed five years. Internal use software costs are included in other assets in the consolidated balance sheets.

Goodwill and Other Intangible Assets

Goodwill and Other Intangible Assets

Intangible assets are acquired assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights or because the asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset, or liability. Our intangible assets relate primarily to loan customer relationships. Intangible assets with definite useful lives are amortized on an accelerated basis over their estimated life. Goodwill and intangible assets are tested for impairment annually or whenever events or changes in circumstances indicate the carrying amount of the assets may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value.

Segment Reporting

Segment Reporting

We have determined that all of our lending divisions and subsidiaries meet the aggregation criteria of ASC 280, Segment Reporting, since all offer similar products and services, operate with similar processes, and have similar customers.

Stock-based Compensation

Stock-based Compensation

We account for all stock-based compensation transactions in accordance with ASC 718, Compensation — Stock Compensation (“ASC 718”), which requires that stock compensation transactions be recognized as compensation expense in the consolidated statement of income and other comprehensive income based on their fair values on the measurement date, which is the date of the grant.

Accumulated Other Comprehensive Income

Accumulated Other Comprehensive Income

Unrealized gains or losses on our available-for-sale securities (after applicable income tax expense or benefit) are included in accumulated other comprehensive income, net. Accumulated comprehensive income (loss), net for the three years ended December 31, 2014 is reported in the accompanying consolidated statements of stockholders’ equity and consolidated statements of income and other comprehensive income.

Income Taxes

Income Taxes

The Company and its subsidiary file a consolidated federal income tax return. We utilize the liability method in accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based upon the difference between the values of the assets and liabilities as reflected in the financial statements and their related tax basis using enacted tax rates in effect for the year in which the differences are expected to be recovered or settled. As changes in tax law or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. A valuation reserve is provided against deferred tax assets unless it is more likely than not that such deferred tax assets will be realized.

Basic and Diluted Earnings Per Common Share

Basic and Diluted Earnings Per Common Share

Basic earnings per common share is based on net income available to common stockholders divided by the weighted-average number of common shares outstanding during the period excluding non-vested stock. Diluted earnings per common share include the dilutive effect of stock options and non-vested stock awards granted using the treasury stock method. A reconciliation of the weighted-average shares used in calculating basic earnings per common share and the weighted average common shares used in calculating diluted earnings per common share for the reported periods is provided in Note 14 — Earnings Per Share.

Fair Values of Financial Instruments

Fair Values of Financial Instruments

ASC 820, Fair Value Measurements and Disclosures (“ASC 820”), defines fair value, establishes a framework for measuring fair value under GAAP and enhances disclosures about fair value measurements. In general, fair values of financial instruments are based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Operations and Summary of Significant Accounting Policies

Operations and Summary of Significant Accounting Policies

Organization and Nature of Business

Texas Capital Bancshares, Inc. (the "Company”), a Delaware corporation, was incorporated in November 1996 and commenced banking operations in December 1998. The consolidated financial statements of the Company include the accounts of Texas Capital Bancshares, Inc. and its wholly owned subsidiary, Texas Capital Bank, National Association (the "Bank”). We serve the needs of commercial businesses and successful professionals and entrepreneurs located in Texas as well as operate several lines of business serving a regional or national clientele of commercial borrowers. We are primarily a secured lender, with our greatest concentration of loans in Texas.

Basis of Presentation

Our accounting and reporting policies conform to accounting principles generally accepted in the United States ("GAAP") and to generally accepted practices within the banking industry. Certain prior period balances have been reclassified to conform to the current period presentation.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The allowance for loan losses, the fair value of stock-based compensation awards, the fair values of financial instruments and the status of contingencies are particularly susceptible to significant change in the near term.

Cash and Cash Equivalents

Cash equivalents include amounts due from banks, interest-bearing deposits and Federal funds sold.

Securities

Securities are classified as trading, available-for-sale or held-to-maturity. Management classifies securities at the time of purchase and re-assesses such designation at each balance sheet date; however, transfers between categories from this re-assessment are rare.

Trading Account

Securities acquired for resale in anticipation of short-term market movements are classified as trading, with realized and unrealized gains and losses recognized in income. To date, we have not had any activity in our trading account.

Held-to-Maturity and Available-for-Sale

Debt securities are classified as held-to-maturity when we have the positive intent and ability to hold the securities to maturity. Held-to-maturity securities are stated at amortized cost. Debt securities not classified as held-to-maturity or trading and marketable equity securities not classified as trading are classified as available-for-sale.

Available-for-sale securities are stated at fair value, with the unrealized gains and losses reported in a separate component of accumulated other comprehensive income (loss), net of tax. The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity, or in the case of mortgage-backed securities, over the estimated life of the security. Such amortization and accretion is included in interest income from securities. Realized gains and losses and declines in value judged to be other-than-temporary are included in gain (loss) on sale of securities. The cost of securities sold is based on the specific identification method.

All securities are available-for-sale as of December 31, 2014 and 2013.

Loans

Loans Held for Investment

Loans held for investment (which include equipment leases accounted for as financing leases) are stated at the amount of unpaid principal reduced by deferred income (net of costs). Interest on loans is recognized using the simple-interest method on the daily balances of the principal amounts outstanding. Loan origination fees, net of direct loan origination costs, and commitment fees, are deferred and amortized as an adjustment to yield over the life of the loan, or over the commitment period, as applicable.

A loan held for investment is considered impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due (both principal and interest) according to the terms of the loan agreement. Reserves on impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate or the fair value of the underlying collateral. Impaired loans, or portions thereof, are charged off when deemed uncollectable.

The accrual of interest on loans is discontinued when there is a clear indication that the borrower’s cash flow may not be sufficient to meet payments as they become due, which is generally when a loan is 90 days past due. When a loan is placed on non-accrual status, all previously accrued and unpaid interest is reversed. Interest income is subsequently recognized on a cash basis as long as the remaining book balance of the asset is deemed to be collectible. If collectability is questionable, then cash payments are applied to principal. A loan is placed back on accrual status when both principal and interest are current and it is probable that we will be able to collect all amounts due (both principal and interest) according to the terms of the loan agreement.

Loans held for investment includes legal ownership interests in mortgage loans that we purchase through our mortgage warehouse lending division. The ownership interests are purchased from unaffiliated mortgage originators who are seeking additional funding through sale of the undivided ownership interests to facilitate their ability to originate loans. The mortgage originator has no obligation to offer and we have no obligation to purchase these interests. The originator closes mortgage loans consistent with underwriting standards established by approved investors, and, at the time of the sale to the investor, our ownership interest and that of the originator are delivered by us to the investor selected by the originator and approved by us. We typically purchase up to a 99% ownership interest in each mortgage with the originator owning the remaining percentage. These mortgage ownership interests are held by us for a period of less than 30 days and more typically 10-20 days. Because of conditions in agreements with originators designed to reduce transaction risks, under Accounting Standards Codification 860, Transfers and Servicing of Financial Assets (“ASC 860”), the ownership interests do not qualify as participating interests. Under ASC 860, the ownership interests are deemed to be loans to the originators and payments we receive from investors are deemed to be payments made by or on behalf of the originator to repay the loan deemed made to the originator. Because we have an actual, legal ownership interest in the underlying residential mortgage loan, these interests are not extensions of credit to the originators that are secured by the mortgage loans as collateral.

Due to market conditions or events of default by the investor or the originator, we could be required to purchase the remaining interests in the mortgage loans and hold them beyond the expected 10-20 days. Mortgage loans acquired under these conditions would require mark-to-market adjustments to income and could require future allocations of the allowance for loan losses or be subject to charge off in the event the loans become impaired. Mortgage loan interests purchased and disposed of as expected receive no allocation of the allowance for loan losses due to the minimal loss experience with these assets.

Allowance for Loan Losses

The allowance for loan losses is established through a provision for loan losses charged against income. The allowance for loan losses includes specific reserves for impaired loans and a general reserve for estimated losses inherent in the loan portfolio at the balance sheet date, but not yet identified with specific loans. Loans deemed to be uncollectable are charged against the allowance when management believes that the collectability of the principal is unlikely and subsequent recoveries, if any, are credited to the allowance. Management’s periodic evaluation of the adequacy of the allowance is based on an assessment of the current loan portfolio, including known inherent risks, adverse situations that may affect the borrowers’ ability to repay, the estimated value of any underlying collateral and current economic conditions.

Other Real Estate Owned

Other real estate owned (“OREO”), which is included in other assets on the consolidated balance sheet, consists of real estate that has been foreclosed. Real estate that has been foreclosed is recorded at the fair value of the real estate, less selling costs, through a charge to the allowance for loan losses, if necessary. Subsequent write-downs required for declines in value are recorded through a valuation allowance, or taken directly to the asset, charged to other non-interest expense.

Premises and Equipment

Premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which range from three to ten years. Gains or losses on disposals of premises and equipment are included in results of operations.

Marketing and Software

Marketing costs are expensed as incurred. Ongoing maintenance and enhancements of websites are expensed as incurred. Costs incurred in connection with development or purchase of internal use software are capitalized and amortized over a period not to exceed five years. Internal use software costs are included in other assets in the consolidated balance sheets.

Goodwill and Other Intangible Assets

Intangible assets are acquired assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights or because the asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset, or liability. Our intangible assets relate primarily to loan customer relationships. Intangible assets with definite useful lives are amortized on an accelerated basis over their estimated life. Goodwill and intangible assets are tested for impairment annually or whenever events or changes in circumstances indicate the carrying amount of the assets may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value.

Segment Reporting

We have determined that all of our lending divisions and subsidiaries meet the aggregation criteria of ASC 280, Segment Reporting, since all offer similar products and services, operate with similar processes, and have similar customers.

Stock-based Compensation

We account for all stock-based compensation transactions in accordance with ASC 718, Compensation — Stock Compensation (“ASC 718”), which requires that stock compensation transactions be recognized as compensation expense in the consolidated statement of income and other comprehensive income based on their fair values on the measurement date, which is the date of the grant.

Accumulated Other Comprehensive Income

Unrealized gains or losses on our available-for-sale securities (after applicable income tax expense or benefit) are included in accumulated other comprehensive income, net. Accumulated comprehensive income (loss), net for the three years ended December 31, 2014 is reported in the accompanying consolidated statements of stockholders’ equity and consolidated statements of income and other comprehensive income.

Income Taxes

The Company and its subsidiary file a consolidated federal income tax return. We utilize the liability method in accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based upon the difference between the values of the assets and liabilities as reflected in the financial statements and their related tax basis using enacted tax rates in effect for the year in which the differences are expected to be recovered or settled. As changes in tax law or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. A valuation reserve is provided against deferred tax assets unless it is more likely than not that such deferred tax assets will be realized.

Basic and Diluted Earnings Per Common Share

Basic earnings per common share is based on net income available to common stockholders divided by the weighted-average number of common shares outstanding during the period excluding non-vested stock. Diluted earnings per common share include the dilutive effect of stock options and non-vested stock awards granted using the treasury stock method. A reconciliation of the weighted-average shares used in calculating basic earnings per common share and the weighted average common shares used in calculating diluted earnings per common share for the reported periods is provided in Note 14 — Earnings Per Share.

Fair Values of Financial Instruments

ASC 820, Fair Value Measurements and Disclosures (“ASC 820”), defines fair value, establishes a framework for measuring fair value under GAAP and enhances disclosures about fair value measurements. In general, fair values of financial instruments are based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows.

Fair Value Disclosures [Abstract]

Fair Value Disclosures

Fair Value Disclosures

ASC 820, Fair Value Measurements and Disclosures (“ASC 820”), defines fair value, establishes a framework for measuring fair value under GAAP and requires enhanced disclosures about fair value measurements. Fair value is defined under ASC 820 as the price that would be received for an asset or paid to transfer a liability (an exit price) in the principal market for the asset or liability in an orderly transaction between market participants on the measurement date.

We determine the fair market values of our assets and liabilities measured at fair value on a recurring and nonrecurring basis using the fair value hierarchy as prescribed in ASC 820. The standard describes three levels of inputs that may be used to measure fair value as provided below.

Level 1 Quoted prices in active markets for identical assets or liabilities.

Level 2 Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 assets include U.S. government and agency mortgage-backed debt securities, municipal bonds, and Community Reinvestment Act funds. This category includes derivative assets and liabilities where values are obtained from independent pricing services.

Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair values requires significant management judgment or estimation. This category also includes impaired loans and OREO where collateral values have been based on third party appraisals; however, due to current economic conditions, comparative sales data typically used in appraisals may be unavailable or more subjective due to lack of market activity.

Assets and liabilities measured at fair value at December 31, 2014 and 2013 are as follows (in thousands):

(1) Securities are measured at fair value on a recurring basis, generally monthly.

(2) Equity securities consist of Community Reinvestment Act funds.

(3) Includes impaired loans that have been measured for impairment at the fair value of the loan’s collateral.

(4) OREO is transferred from loans to OREO at fair value less selling costs.

(5) Fair value of loans and OREO is measured on a nonrecurring basis, generally annually or more often as warranted by market and economic conditions

(6) Derivative assets and liabilities are measured at fair value on a recurring basis, generally quarterly.

Level 3 Valuations

Financial instruments are considered Level 3 when their values are determined using pricing models, discounted cash flow methodologies or similar techniques and at least one significant model assumption or input is unobservable. Level 3 financial instruments also include those for which the determination of fair value requires significant management judgment or estimation. Currently, we measure fair value for certain loans on a nonrecurring basis as described below.

Loans

During the years ended December 31, 2014 and 2013, certain impaired loans were reevaluated and reported at fair value through a specific valuation allowance allocation of the allowance for possible loan losses based upon the fair value of the underlying collateral. The $23.5 million total above includes impaired loans at December 31, 2014 with a carrying value of $29.2 million that were reduced by specific valuation allowance allocations totaling $5.7 million for a total reported fair value of $23.5 million based on collateral valuations utilizing Level 3 valuation inputs. The $13.5 million total above includes impaired loans at December 31, 2013 with a carrying value of $14.9 million that were reduced by specific valuation allowance allocations totaling $1.4 million for a total reported fair value of $13.5 million based on collateral valuations utilizing Level 3 valuation inputs. Fair values were based on third party appraisals.

OREO

Certain foreclosed assets, upon initial recognition, were valued based on third party appraisals. At December 31, 2014 and 2013, OREO had a carrying value of $568,000 and $5.1 million, respectively, with no specific valuation allowance. The fair value of OREO was computed based on third party appraisals, which are Level 3 valuation inputs.

Fair Value of Financial Instruments

Generally accepted accounting principles require disclosure of fair value information about financial instruments, whether or not recognized on the balance sheet, for which it is practical to estimate that value. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. This disclosure does not and is not intended to represent the fair value of the Company.

A summary of the carrying amounts and estimated fair values of financial instruments is as follows (in thousands):

	December 31, 2014				December 31, 2013

The following methods and assumptions were used by the Company in estimating its fair value disclosures for financial instruments:

Cash and cash equivalents

The carrying amounts reported in the consolidated balance sheet for cash and cash equivalents approximate their fair value, which is characterized as a Level 1 asset in the fair value hierarchy.

Securities

The fair value of investment securities is based on prices obtained from independent pricing services which are based on quoted market prices for the same or similar securities, which is characterized as a Level 2 asset in the fair value hierarchy. We have obtained documentation from the primary pricing service we use about their processes and controls over pricing. In addition, on a quarterly basis we independently verify the prices that we receive from the service provider using two additional independent pricing sources. Any significant differences are investigated and resolved.

Loans, net

Loans are characterized as Level 3 assets in the fair value hierarchy. For variable-rate loans that reprice frequently with no significant change in credit risk, fair values are generally based on carrying values. The fair value for all other loans is estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. The carrying amount of accrued interest approximates its fair value. The carrying amount of mortgage finance loans approximates fair value.

Derivatives

The estimated fair value of the interest rate swaps are obtained from independent pricing services based on quoted market prices for the same or similar derivative contracts and are characterized as a Level 2 asset in the fair value hierarchy. On a quarterly basis, we independently verify the fair value using an additional independent pricing source.

Deposits

Deposits are characterized as Level 3 liabilities in the fair value hierarchy. The carrying amounts for variable-rate money market accounts approximate their fair value. Fixed-term certificates of deposit fair values are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities.

Federal funds purchased, customer repurchase agreements, other borrowings, subordinated notes and trust preferred subordinated debentures

The carrying value reported in the consolidated balance sheet for Federal funds purchased, customer repurchase agreements and other short-term, floating rate borrowings approximates their fair value, which is characterized as a Level 2 asset in the fair value hierarchy. The fair value of any fixed rate short-term borrowings and trust preferred subordinated debentures are estimated using a discounted cash flow calculation that applies interest rates currently being offered on similar borrowings, which is characterized as a Level 3 liability in the fair value hierarchy. The subordinated notes are publicly traded and are valued based on market prices, which is characterized as a Level 2 liability in the fair value hierarchy.

Income Taxes

We have a gross deferred tax asset of $65.5 million and $60.2 million at December 31, 2014 and 2013, respectively, which relates primarily to our allowance for loan losses, loan origination fees and stock compensation. Management believes it is more likely than not that all of the deferred tax assets will be realized. Our net deferred tax asset is included in other assets in the consolidated balance sheet.

Income tax expense/(benefit) consists of the following for the years ended (in thousands):

ASC 740-10, Income Taxes — Accounting for Uncertainties in Income Taxes (“ASC 740-10”) prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. Benefits from tax positions should be recognized in the financial statements only when it is more likely than not that the tax position will be sustained upon examination by the appropriate taxing authority that would have full knowledge of all relevant information. A tax position that meets the more-likely-than-not recognition threshold is measured at the largest amount of cumulative benefit that is greater than fifty percent likely of being realized upon ultimate settlement. Tax positions that previously failed to meet the more-likely-than-not recognition threshold should be recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not recognition threshold should be derecognized in the first subsequent financial reporting period in which that threshold is no longer met. ASC 740-10 also provides guidance on the accounting for and disclosure of unrecognized tax benefits, interest and penalties.

We file income tax returns in the U.S. federal jurisdiction and several U.S. state jurisdictions. We are no longer subject to U.S. federal income tax examinations by tax authorities for years before 2011.

The reconciliation of income computed at the U.S. federal statutory tax rates to income tax expense (benefit) is as follows:

Employee Benefits

Employee Benefits

We have a qualified retirement plan, with a salary deferral feature designed to qualify under Section 401 of the Internal Revenue Code (“the 401(k) Plan”). The 401(k) Plan permits our employees to defer a portion of their compensation. Matching contributions may be made in amounts and at times determined by the Company. We contributed approximately $4.5 million, $3.7 million, and $2.7 million for the years ended December 31, 2014, 2013 and 2012, respectively. Employees are eligible to participate in the 401(k) Plan when they meet certain requirements concerning minimum age and period of credited service. All contributions to the 401(k) Plan are invested in accordance with participant elections among certain investment options.

During 2000, we implemented an Employee Stock Purchase Plan (“ESPP”). Employees are eligible for the plan when they have met certain requirements concerning period of credited service and minimum hours worked. Eligible employees may contribute a minimum of 1% to a maximum of 10% of eligible compensation up to the Section 423 of the Internal Revenue Code limit of $25,000. In 2006, stockholders approved the 2006 ESPP, which allocated 400,000 shares for purchase. As of December 31, 2014, 2013 and 2012, 102,836, 93,388 and 85,013 shares had been purchased on behalf of the employees under the 2006 ESPP.

As of December 31, 2014, we had three equity-based compensation plans, the 1999 Stock Omnibus Plan (“1999 Plan”), the 2005 Long-Term Incentive Plan (“2005 Plan”) and the 2010 Long-Term Incentive Plan (“2010 Plan”). The 1999 Plan is no longer available for grants of equity based compensation; however, options to purchase shares previously issued under the plan will remain outstanding and be subject to administration by the Human Resources Committee of our board of directors. Under both the 2005 and 2010 Plans, equity-based compensation grants were made by the board of directors, or its designated committee. Grants are subject to vesting requirements. Under the 2005 and 2010 Plans, we may grant, among other things, nonqualified stock options, incentive stock options, restricted stock units (“RSUs”), stock appreciation rights (“SARs”), cash-based performance units or any combination thereof. Both Plans include grants for employees and directors. Total shares authorized under the 2005 plan are 1,500,000, with 700,000 authorized under the 2010 Plan. Total shares which may be issued under the 2005 Plan at December 31, 2014, 2013 and 2012 were 44,655, 43,495 and 26,615, respectively. Total shares which may be issued under the 2010 Plan at December 31, 2014, 2013 and 2012 were 180,120, 218,820 and 363,020, respectively.

The fair value of our stock option and SAR grants are estimated at the date of grant using the Black-Scholes option pricing model. The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options which have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions including the expected stock price volatility. Because our employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management’s opinion, the existing models do not necessarily provide the best single measure of the fair value of its employee stock options.

The fair value of the options and stock appreciation rights were estimated at the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions:

	2014		2013		2012
Risk-free rate	1.46	%	1.17	%	0.76	%
Market price volatility factor	0.402		0.409		0.404
Weighted-average expected life of options	5 years		5 years		5 years

Market price volatility and expected life of options is based on historical data and other factors.

A summary of our stock option activity and related information for 2014, 2013 and 2012 is as follows:

The RSUs granted during 2014, 2013 and 2012 vest ratably over four to five years. Compensation cost for restricted stock units was $4,098,000, $3,551,000, $4,875,000 for years ended December 31, 2014, 2013 and 2012, respectively. The weighted average remaining contractual life of RSUs currently outstanding is 8.11 years.

Total compensation cost for all share-based arrangements, net of taxes, was $3,008,000, $2,677,000 and $3,626,000 for the years ended December 31, 2014, 2013 and 2012, respectively.

Unrecognized stock-based compensation expense related to SAR grants issued through December 31, 2014 was $1.1 million. At December 31, 2014, the weighted average period over which this unrecognized expense was expected to be recognized was 3.2 years. Unrecognized stock-based compensation expense related to RSU grants through December 31, 2014 was $10.6 million. At December 31, 2014, the weighted average period over which this unrecognized expense was expected to be recognized was 3.5 years.

Cash flows from financing activities included $2,929,000, $1,200,000 and $7,769,000 in cash inflows from excess tax benefits related to stock compensation in 2014, 2013 and 2012, respectively.

Upon share option exercise, new shares are issued as opposed to treasury shares.

Pursuant to the 2010 Long-term Incentive Plan, we granted a total of 171,808, 173,035 and 344,127 cash-based performance units in 2014, 2013 and 2012, with a total of 502,532 outstanding at December 31, 2014. Of the outstanding units at December 31, 2014, 328,916 are service-based and vest ratably over a period of five years. Additionally, 173,616 units contain both service and performance based vesting requirements: 25-50% of the units will vest on the third anniversary of the date of grant, and the balance will vest based on attainment of certain performance metrics developed by the Human Resources Committee. Since these units have a cash payout feature, they are accounted for under the liability method and the related expense is based on the stock price at period end. Compensation cost for the units was $9,949,000, $17,287,000 and $6,440,000 for the years ended December 31, 2014, 2013, and 2012 respectively. At December 31, 2014, the weighted average remaining contractual life of the units was 8.08 years.

Total compensation cost for all cash-based arrangements, net of taxes, for the years ended December 31, 2014, 2013 and 2012 was $6,467,000, $11,237,000 and $4,186,000, respectively.

Goodwill and Other Intangible Assets

Goodwill and Other Intangible Assets

In May 2013, we acquired the assets of a premium finance company and recorded a total intangible asset of $2.1 million. Of this total, $954,000 was allocated to goodwill, $554,000 to customer relationships, $457,000 to developed technology and $98,000 to trade name. The $554,000 customer relationship intangible will be amortized over 14 years, the $457,000 technology intangible will be amortized over 7 years, and the $98,000 intangible related to the trade name was determined to have an indefinite life.

Goodwill and other intangible assets at December 31, 2014 and 2013 are summarized as follows (in thousands):

Financial Instruments with Off-Balance Sheet Risk

Risks and Uncertainties [Abstract]

Financial Instruments with Off-Balance Sheet Risk

Financial Instruments with Off-Balance Sheet Risk

The Bank is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit that involve varying degrees of credit risk in excess of the amount recognized in the consolidated balance sheets. The Bank’s exposure to credit loss in the event of non-performance 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 Bank uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. The amount of collateral obtained, if deemed necessary, is based on management’s credit evaluation of the borrower.

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 generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Bank evaluates each customer’s credit-worthiness on a case-by-case basis.

Standby letters of credit are conditional commitments issued by the Bank to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.

At December 31, 2014 and 2013, commitments to extend credit and standby and commercial letters of credit were as follows (in thousands):

	December 31,
	2014		2013
Commitments to extend credit	$	5,324,460	$	3,674,391
Standby letters of credit	177,808		145,662

Subordinated Borrowings [Abstract]

Trust Preferred Subordinated Debentures

Long-Term Debt

From November 2002 to September 2006 various Texas Capital Statutory Trusts were created and subsequently issued floating rate trust preferred securities in various private offerings totaling $113.4 million. As of December 31, 2014, the details of the trust preferred subordinated debentures are summarized below (in thousands):

	Texas Capital Bancshares Statutory Trust I	Texas Capital Statutory Trust II	Texas Capital Statutory Trust III	Texas Capital Statutory Trust IV	Texas Capital Statutory Trust V

Maturity date	November 2032	April 2033	December 2035	June 2036	December 2036

On September 21, 2012, we issued $111.0 million of subordinated notes. The notes mature in September 2042 and bear interest at a rate of 6.50% per annum, payable quarterly. The indenture governing the notes contains customary covenants and restrictions.

On January 31, 2014, the Bank issued $175.0 million of subordinated notes in an offering to institutional investors exempt from registration under Section 3(a)(2) of the Securities Act of 1933 and 12 C.F.R. Part 16. Net proceeds from the transaction were $172.4 million. The notes mature in January 2026 and bear interest at a rate of 5.25% per annum, payable semi-annually. The notes are unsecured and are subordinate to the Bank’s obligations to its depositors, its obligations under banker’s acceptances and letters of credit, certain obligations to Federal Reserve Banks and the FDIC and the Bank’s obligations to its other creditors, except any obligations which expressly rank on a parity with or junior to the notes. The notes qualify as Tier 2 capital for regulatory capital purposes, subject to applicable limitations.

Interest payments on all long-term debt are deductible for federal income tax purposes.

Because our bank had less than $15.0 billion in total consolidated assets as of December 31, 2009, we are allowed to continue to classify our trust preferred securities, all of which were issued prior to May 19, 2010, as Tier 1 capital.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

Derivative Financial Instruments

The fair value of derivative positions outstanding is included in other assets and other liabilities in the accompanying consolidated balance sheets on a net basis when a right of offset exists, based on transactions with a single counterparty that are subject to a legally enforceable master netting agreement.

During 2014 and 2013, we entered into certain interest rate derivative positions that were not designated as hedging instruments. These derivative positions relate to transactions in which we enter into an interest rate swap, cap and/or floor with a customer while at the same time entering into an offsetting interest rate swap, cap and/or floor with another financial institution. In connection with each swap transaction, we agree to pay interest to the customer on a notional amount at a variable interest rate and receive interest from the customer on a similar notional amount at a fixed interest rate. At the same time, we agree to pay another financial institution the same fixed interest rate on the same notional amount and receive the same variable interest rate on the same notional amount. The transaction allows our customer to effectively convert a variable rate loan to a fixed rate. Because we act as an intermediary for our customer, changes in the fair value of the underlying derivative contracts substantially offset each other and do not have a material impact on our results of operations.

The notional amounts and estimated fair values of interest rate derivative positions outstanding at December 31, 2014 and 2013 presented in the following table (in thousands):

	December 31, 2014								December 31, 2013

Net derivatives included in the consolidated balance sheets			$	31,176		$	31,176				$	14,690		$	14,690

The weighted-average receive and pay interest rates for interest rate swaps outstanding at December 31, 2014 and 2013 were as follows:

	December 31, 2014 Weighted-Average Interest  Rate				December 31, 2013 Weighted-Average Interest  Rate
	Received		Paid		Received		Paid
Non-hedging interest rate swaps	2.79	%	4.82	%	2.99	%	4.89	%

The weighted-average strike rate for outstanding interest rate caps was 1.44% at December 31, 2014 and 1.87% at December 31, 2013.

Our credit exposure on interest rate swaps and caps is limited to the net favorable value and interest payments of all swaps and caps by each counterparty. In such cases collateral may be required from the counterparties involved if the net value of the swaps and caps exceeds a nominal amount considered to be immaterial. Our credit exposure, net of any collateral pledged, relating to interest rate swaps and caps was approximately $31.2 million at December 31, 2014 and approximately $14.7 million at December 31, 2013, all of which relates to bank customers. Collateral levels are monitored and adjusted on a regular basis for changes in interest rate swap and cap values. At December 31, 2014 and 2013, we had $30.2 million and $10.7 million in cash collateral pledged for these derivatives included in interest-bearing deposits.

Commercial Loans and Leases.    Our commercial loan portfolio is comprised of lines of credit for working capital and term loans and leases to finance equipment and other business assets. Our energy production loans are generally collateralized with proven reserves based on appropriate valuation standards and take into account the risk of oil and gas price volatility. Our commercial loans and leases are underwritten after carefully evaluating and understanding the borrower’s ability to operate profitably. Our underwriting standards are designed to promote relationship banking rather than to make loans on a transaction basis. Our lines of credit typically are limited to a percentage of the value of the assets securing the line. Lines of credit and term loans typically are reviewed annually and are supported by accounts receivable, inventory, equipment and other assets of our clients’ businesses.

Mortgage finance loans.    Our mortgage finance loans consist of ownership interests purchased in single-family residential mortgages funded through our mortgage finance group. These loans are typically on our balance sheet for 10 to 20 days. We have agreements with mortgage lenders and purchase interests in individual loans they originate. All loans are underwritten consistent with established programs for permanent financing with financially sound investors. Substantially all loans are conforming loans. December 31, 2014 and 2013 balances are stated net of $358.3 million and $33.1 million participations sold, respectively.

Construction Loans.    Our construction loan portfolio consists primarily of single- and multi-family residential properties and commercial projects used in manufacturing, warehousing, service or retail businesses. Our construction loans generally have terms of one to three years. We typically make construction loans to developers, builders and contractors that have an established record of successful project completion and loan repayment and have a substantial equity investment in the borrowers. Loan amounts are derived primarily from the bank's evaluation of expected cash flows available to service debt from stabilized projects under hypothetically stressed conditions. Construction loans are also based in part upon estimates of costs and value associated with the completed project. Sources of repayment for these types of loans may be pre-committed permanent loans from other lenders, sales of developed property, or an interim loan commitment from us until permanent financing is obtained. The nature of these loans makes ultimate repayment sensitive to overall economic conditions. Borrowers may not be able to correct conditions of default in loans, increasing risk of exposure to classification, non-performing status, reserve allocation and actual credit loss and foreclosure. These loans typically have floating rates and commitment fees.

Real Estate Loans.    A portion of our real estate loan portfolio is comprised of loans secured by properties other than market risk or investment-type real estate. Market risk loans are real estate loans where the primary source of repayment is expected to come from the sale, permanent financing or lease of the real property collateral. We generally provide temporary financing for commercial and residential property. These loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Our real estate loans generally have maximum terms of five to seven years, and we provide loans with both floating and fixed rates. We generally avoid long-term loans for commercial real estate held for investment. Real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy. Appraised values may be highly variable due to market conditions and the impact of the inability of potential purchasers and lessees to obtain financing and a lack of transactions at comparable values.

At December 31, 2014 and 2013, we had a blanket floating lien on certain real estate-secured loans, mortgage finance loans and also certain securities used as collateral for FHLB borrowings.

Portfolio Geographic Concentration

As of December 31, 2014, a majority of our loans held for investment, excluding our mortgage finance loans and other national lines of business, were to businesses with headquarters and operations in Texas. This geographic concentration subjects the loan portfolio to the general economic conditions within this area. Additionally, we make loans to these businesses and individuals secured by assets located outside of Texas. The risks created by the geographic distribution of loans have been considered by management in the determination of the adequacy of the allowance for loan losses. Management believes the allowance for loan losses is appropriate to cover estimated losses on loans at each balance sheet date.

Summary of Loan Losses

The allowance for loan losses is comprised of specific reserves for impaired loans and an estimate of losses inherent in the portfolio at the balance sheet date, but not yet identified with specified loans. We regularly evaluate our reserve for loan losses to maintain an appropriate level to absorb estimated loan losses inherent in the loan portfolio. Factors contributing to the determination of reserves include the creditworthiness of the borrower, changes in the value of pledged collateral, and general economic conditions. All loan commitments rated substandard or worse and greater than $500,000 are specifically reviewed for loss potential. For loans deemed to be impaired, a specific allocation is assigned based on the losses expected to be realized from those loans. For purposes of determining the general reserve, the portfolio is segregated by product types to recognize differing risk profiles among categories, and then further segregated by credit grades. Credit grades are assigned to all loans. Each credit grade is assigned a risk factor, or reserve allocation percentage. These risk factors are multiplied by the outstanding principal balance and risk-weighted by product type to calculate the required reserve. A similar process is employed to calculate a reserve assigned to off-balance sheet commitments, specifically unfunded loan commitments and letters of credit, and any needed reserve is recorded in other liabilities. Even though portions of the allowance may be allocated to specific loans, the entire allowance is available for any credit that, in management’s judgment, should be charged off.

We have several pass credit grades that are assigned to loans based on varying levels of risk, ranging from credits that are secured by cash or marketable securities, to watch credits which have all the characteristics of an acceptable credit risk but warrant more than the normal level of monitoring. Within our criticized/classified credit grades are special mention, substandard, and doubtful. Special mention loans are those that are currently protected by sound worth and paying capacity of the borrower, but that are potentially weak and constitute an additional credit risk. The loan has the potential to deteriorate to a substandard grade due to the existence of financial or administrative deficiencies. Substandard loans have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that we will sustain some loss if the deficiencies are not corrected. Some substandard loans are inappropriately protected by sound worth and paying capacity of the borrower and of the collateral pledged and may be considered impaired. Substandard loans can be accruing or can be on non-accrual depending on the circumstances of the individual loans. Loans classified as doubtful have all the weaknesses inherent in substandard loans with the added characteristics that the weaknesses make collection or liquidation in full highly questionable and improbable. The possibility of loss is extremely high. All doubtful loans are on non-accrual.

The reserve allocation percentages assigned to each credit grade have been developed based primarily on an analysis of our historical loss rates. The allocations are adjusted for certain qualitative factors, including general economic conditions, changes in credit policies and lending standards. Changes in the trend and severity of problem loans can cause the estimation of losses to differ from past experience. In addition, the reserve considers the results of reviews performed by independent third party reviewers as reflected in their confirmations of assigned credit grades within the portfolio. The portion of the allowance that is not derived by the allowance allocation percentages compensates for the uncertainty and complexity in estimating loan and lease losses including factors and conditions that may not be fully reflected in the determination and application of the allowance allocation percentages. Examples of risks that support the Bank's maintaining an unallocated reserve include the possibility of precipitous negative changes in economic conditions and borrowers' submission of financial statements or certifications of collateral value that subsequently prove to be materially inaccurate for reason of either misstatement or omission of critical information. These situations, while not common, do not necessarily correlate well with the general risk profile presented by assigned credit grade and product type categories. We evaluate many such factors and conditions in determining the unallocated portion of the allowance, including amount and frequency of losses attributable to issues not specifically addressed or included in the determination and application of the allowance allocation percentages. The allowance is considered appropriate, given management’s assessment of potential losses within the portfolio as of the evaluation date, the significant growth in the loan and lease portfolio, current economic conditions in the Company’s market areas and other factors.

The methodology used in the periodic review of reserve adequacy, which is performed at least quarterly, is designed to be dynamic and responsive to changes in portfolio credit quality. The changes are reflected in the general reserve and in specific reserves as the collectability of larger classified loans is evaluated with new information. As our portfolio has matured, historical loss ratios have been closely monitored, and our reserve adequacy relies primarily on our loss history. The review of reserve adequacy is performed by executive management and presented to a committee of our board of directors for their review. The committee reports to the board as part of the board's review on a quarterly basis of the Company's consolidated financial statements.

The following tables summarize the credit risk profile of our loan portfolio by internally assigned grades and non-accrual status as of December 31, 2014 and 2013 (in thousands):

We have traditionally maintained an unallocated reserve component to compensate for the uncertainty and complexity in estimating loan and lease losses including factors and conditions that may not be fully reflected in the determination and application of the allowance allocation percentages. We believe the level of unallocated reserves at December 31, 2014 is warranted due to the continued uncertain economic environment which has produced losses, including those resulting from borrowers' misstatement of financial information or inaccurate certification of collateral values. Such losses are not necessarily correlated with historical loss trends or general economic conditions. Our methodology used to calculate the allowance considers historical losses; however, the historical loss rates for specific product types or credit risk grades may not fully incorporate the effects of continued weakness in the economy.

Generally we place loans on non-accrual when there is a clear indication that the borrower’s cash flow may not be sufficient to meet payments as they become due, which is generally when a loan is 90 days past due. When a loan is placed on non-accrual status, all previously accrued and unpaid interest is reversed. Interest income is subsequently recognized on a cash basis as long as the remaining unpaid principal amount of the loan is deemed to be fully collectible. If collectability is questionable, then cash payments are applied to principal. We recognized $1.7 million in interest income on non-accrual loans during 2014 compared to $2.4 million in 2013 and $2.6 million in 2012. Additional interest income that would have been recorded if the loans had been current during the years ended December 31, 2014, 2013 and 2012 totaled $2.1 million, $2.5 million and $2.4 million, respectively. As of December 31, 2014, $310,000 of our non-accrual loans were earning on a cash basis, compared to none at December 31, 2013. A loan is placed back on accrual status when both principal and interest are current and it is probable that we will be able to collect all amounts due (both principal and interest) according to the terms of the loan agreement.

A loan held for investment is considered impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due (both principal and interest) according to the terms of the loan agreement. In accordance with FASB ASC 310 Receivables, we have included all restructured loans in our impaired loan totals. The following tables detail our impaired loans, by portfolio class as of December 31, 2014 and 2013 (in thousands):

(1) Loans past due 90 days and still accruing includes premium finance loans of $3.7 million. These loans are generally secured by obligations of insurance carriers to refund premiums on cancelled insurance policies. The refund of premiums from the insurance carriers can take 180 days or longer from the cancellation date.

Restructured loans are loans on which, due to the borrower’s financial difficulties, we have granted a concession that we would not otherwise consider for borrowers of similar credit quality. This may include a transfer of real estate or other assets from the borrower, a modification of loan terms, or a combination of the two. Modifications of terms that could potentially qualify as a restructuring include reduction of contractual interest rate, extension of the maturity date at a contractual interest rate lower than the current rate for new debt with similar risk, or a reduction of the face amount of debt, or forgiveness of either principal or accrued interest. As of December 31, 2014 and December 31, 2013, we had $1.8 million and $1.9 million, respectively, in loans considered restructured that are not on non-accrual. These loans did not have unfunded commitments at December 31, 2014 or 2013. Of the non-accrual loans at December 31, 2014 and 2013, $12.1 million and $17.8 million, respectively, met the criteria for restructured. These loans had no unfunded commitments at their respective balance sheet dates. A loan continues to qualify as restructured until a consistent payment history or change in borrower’s financial condition has been evidenced, generally no less than twelve months. Assuming that the restructuring agreement specifies an interest rate at the time of the restructuring that is greater than or equal to the rate that we are willing to accept for a new extension of credit with comparable risk, then the loan no longer has to be considered a restructuring if it is in compliance with modified terms in calendar years after the year of the restructure.

The following tables summarize, as of December 31, 2014 and 2013, loans that have been restructured during 2014 and 2013 (in thousands):

December 31, 2014
	Number of Contracts	Pre-Restructuring Outstanding Recorded Investment		Post-Restructuring Outstanding  Recorded Investment
Real estate - commercial	1	$	1,441	$	1,441
Commercial business loans	1	$	95	$	80
Total new restructured loans in 2014	2	$	1,536	$	1,521

December 31, 2013
	Number of Contracts	Pre-Restructuring Outstanding Recorded Investment		Post-Restructuring Outstanding  Recorded Investment
Commercial business loans	3	$	10,823	$	8,921
Real estate market risk	1	892		874
Total new restructured loans in 2013	4	$	11,715	$	9,795

The restructured loans generally include terms to temporarily place the loan on interest only, extend the payment terms or reduce the interest rate. We did not forgive any principal on the above loans. The $15,000 decrease in the post-restructuring recorded investment compared to the pre-restructuring recorded investment is due to paydowns. At December 31, 2014, $1.5 million of the above loans restructured in 2014 are on non-accrual. The restructuring of the loans did not have a significant impact on our allowance for loan losses at December 31, 2014 or 2013.

The following table provides information on how loans were modified as a restructured loan during the year ended December 31, 2014 and 2013 (in thousands):

	December 31,
	2014		2013

Combination of maturity extension and payment schedule adjustment	80		8,921
Total	$	1,521	$	9,795

As of December 31, 2014 and 2013, we did not have any loans that were restructured within the last 12 months that subsequently defaulted.

Stockholders' Equity Note [Abstract]

Stockholders' Equity

Stockholders’ Equity

In January 2009, we issued $75 million of perpetual preferred stock and related warrants under the U.S. Department of Treasury’s voluntary Capital Purchase Program. The preferred stock was repurchased in May 2009 and the U.S. Treasury auctioned the related warrants in the first quarter of 2010. As of December 31, 2014, warrants to purchase 581,500 shares at $14.84 per share are still outstanding.

On March 28, 2013, we completed a sale of 6.0 million shares of 6.5% non-cumulative preferred stock, par value $0.01, with a liquidation preference of $25 per share, in a public offering. Dividends on the preferred stock are not cumulative and will be paid when declared by our board of directors to the extent that we have lawfully available funds to pay dividends. If declared, dividends will accrue and be payable quarterly, in arrears, on the liquidation preference amount, on a non-cumulative basis, at a rate of 6.50% per annum. We paid $9.8 million in dividends on the preferred stock for the year ended December 31, 2014 compared to $7.0 million for the same period of 2013. Holders of preferred stock do not have voting rights, except with respect to authorizing or increasing the authorized amount of senior stock, certain changes in the terms of the preferred stock, certain dividend non-payments and as otherwise required by applicable law. Net proceeds from the sale totaled $145.0 million. The additional equity was used for general corporate purposes, including funding regulatory capital infusions into the Bank.

In January 2014, we completed an offering of 1.9 million shares of our common stock. Net proceeds from the sale totaled $106.5 million. The net proceeds of the offering were available to the Company for general corporate purposes, including retirement of $15.0 million of short-term debt that was outstanding at December 31, 2013, and additional capital to support continued loan growth.

On November 12, 2014, we completed a sale of 2.5 million of our common stock in a public offering. Net proceeds from the sale totaled $149.6 million. The additional equity will be used for general corporate purposes and additional capital to support continued loan growth.

Regulatory Capital Requirements [Abstract]

Regulatory Restrictions

Regulatory Restrictions

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

In July 2013, the Federal Reserve published final rules for the adoption of the Basel III regulatory capital framework (the "Basel III Capital Rules"). The Basel III Capital Rules, among other things, (i) introduce a new capital measure called "Common Equity Tier 1," (ii) specify that Tier 1 capital consist of Common Equity Tier 1 and "Additional Tier 1 Capital" instruments meeting specified requirements, (iii) define Common Equity Tier 1 narrowly by requiring that most deductions/adjustments to regulatory capital measures be made to Common Equity Tier 1 and not to the other components of capital and (iv) expand the scope of the deductions/adjustments as compared to existing regulations. The Basel III Capital Rules became effective for us on January 1, 2015 with certain transition provisions fully phased in on January 1, 2019. Based on our initial assessment of the Basel III Capital Rules, we do not believe they will have a material impact on the Company or our bank. We believe we will meet the capital adequacy requirements under the Basel III Capital Rules on a fully phased-in basis when we commence filing 2015 reports with the FDIC and OCC.

Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios of total and Tier 1 capital to risk-weighted assets, and of Tier 1 capital to average assets, each as defined in the regulations. Management believes, as of December 31, 2014, that the Company and the Bank meet all capital adequacy requirements to which they are subject.

Financial institutions are categorized as well capitalized or adequately capitalized, based on minimum total risk-based, Tier 1 risk-based and Tier 1 leverage ratios. As shown in the table below, the Company’s capital ratios exceeded the regulatory definition of adequately capitalized as of December 31, 2014 and 2013. Based upon the information in its most recently filed call report, the Bank met the capital ratios necessary to be well capitalized. The regulatory authorities can apply changes in classification of assets and such change may retroactively subject the Company to change in capital ratios. Any such change could result in reducing one or more capital ratios below well-capitalized status. In addition, a change may result in imposition of additional assessments by the FDIC or could result in regulatory actions that could have a material effect on condition and results of operations.

Because our bank had less than $15.0 billion in total consolidated assets as of December 31, 2009, we are allowed to continue to classify our trust preferred securities, all of which were issued prior to May 19, 2010, as Tier 1 capital.

The table below summarizes our capital ratios:

Dividends that may be paid by subsidiary banks are routinely restricted by various regulatory authorities. The amount that can be paid in any calendar year without prior approval of the Bank’s regulatory agencies cannot exceed the lesser of net profits (as defined) for that year plus the net profits for the preceding two calendar years, or retained earnings. The Basel III Capital Rules, will further limit the amount of dividends that be paid by our bank. No dividends were declared or paid on our common stock during 2014, 2013 or 2012.

The required reserve balances at the Federal Reserve at December 31, 2014 and 2013 were approximately $88,155,000 and $51,692,000, respectively.
