NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—UNAUDITED

(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.

The consolidated interim financial statements have been prepared without audit. Certain information and footnote disclosures presented in accordance with GAAP have been condensed or omitted. In the opinion of management, the interim financial statements include all normal and recurring adjustments and the disclosures made are adequate to make the interim financial information not misleading. The consolidated financial statements have been prepared in accordance with GAAP for interim financial information and the instructions to Form 10-Q adopted by the Securities and Exchange Commission (“SEC”). Accordingly, the financial statements do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with our consolidated financial statements, and notes thereto, for the year ended December 31, 2014, included in our Annual Report on Form 10-K filed with the SEC on February 19, 2015 (the “2014 Form 10-K”). Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for a full year or any future period.

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.

(2) EARNINGS PER COMMON SHARE

The following table presents the computation of basic and diluted earnings per share (in thousands except per share data):

	Three months ended   June 30,				Six months ended   June 30,
	2015		2014		2015		2014
Numerator:
Net income	$	37,937	$	33,421	$	72,987	$	61,686
Preferred stock dividends	2,437		2,437		4,875		4,875
Net income available to common stockholders	35,500		30,984		$	68,112	56,811
Denominator:
Denominator for basic earnings per share— weighted average shares	45,790,093		43,075,213		45,774,461		42,735,580
Effect of employee stock-based awards(1)	229,378		336,993		219,448		359,794
Effect of warrants to purchase common stock	423,942		432,809		411,281		486,113
Denominator for dilutive earnings per share—adjusted weighted average shares and assumed conversions	46,443,413		43,845,015		46,405,190		43,581,487
Basic earnings per common share	$	0.78	$	0.72	$	1.49	$	1.33
Diluted earnings per common share	$	0.76	$	0.71	$	1.47	$	1.30

(1) Stock options, SARs and RSUs outstanding of 173,382 at June 30, 2015 and 46,000 at June 30, 2014 have not been included in diluted earnings per share because to do so would have been anti-dilutive for the periods presented.

(3) SECURITIES

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 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.

At June 30, 2015, our net unrealized gain on the available-for-sale securities portfolio was $1.6 million compared to $2.0 million at December 31, 2014. As a percent of outstanding balances, the unrealized gain was 4.70% and 4.99% at June 30, 2015, and December 31, 2014, respectively. The decrease in the unrealized gain percentage at June 30, 2015 is related to the reduction in the portfolio balance due to paydowns and maturities.

Securities with carrying values of approximately $25.5 million were pledged to secure certain borrowings and deposits at June 30, 2015. Of the pledged securities at June 30, 2015, approximately $8.4 million were pledged for certain deposits, and approximately $17.1 million were pledged for repurchase agreements.

The following table discloses, as of June 30, 2015 and December 31, 2014, 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 June 30, 2015, we owned one security with an unrealized loss position. This security is a publicly traded equity fund and is subject to market pricing volatility. We do not believe 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.

Commercial Loans and Leases. Our commercial loan and lease 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 transactional 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 interests 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. Balances as of June 30, 2015 and December 31, 2014 are stated net of $541.0 million and $358.3 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, the impact of the inability of potential purchasers and lessees to obtain financing and a lack of transactions at comparable values.

11

At June 30, 2015 and December 31, 2014, we had a blanket floating lien on certain real estate-secured loans, mortgage finance loans and certain securities used as collateral for Federal Home Loan Bank (“FHLB”) borrowings.

Portfolio Geographic Concentration

As of June 30, 2015, a substantial 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 appropriateness of the allowance for loan losses. Management believes the allowance for loan losses is appropriate to cover probable losses inherent in the loan portfolio at each balance sheet date.

Summary of Loan Loss Experience

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 credit-worthiness 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 the current 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 insufficiently protected by the current 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, on the basis of currently existing facts, conditions and values, 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 for such things as general economic conditions and 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 reflects the results of reviews performed by the Company's independent Credit Review function as reflected in their confirmations of assigned credit grades within the portfolio. The Credit Review function reports to the Credit Risk Committee of the Company's board of directors with administrative oversight from the Company's Chief Risk Officer. 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 Company'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 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. We consider the allowance to be appropriate, given management’s assessment of probable 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.

12

The methodology used in the periodic review of reserve appropriateness, 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 appropriateness relies primarily on our loss history. The review of the reserve appropriateness 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 June 30, 2015 and December 31, 2014 (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 June 30, 2015 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. As of June 30, 2015, $904,100 of our non-accrual loans were earning on a cash basis compared to $310,000 at December 31, 2014. 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.

15

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 ASC 310 Receivables ("ASC 310"), we have also included all restructured loans in our impaired loan totals. The following tables detail our impaired loans, by portfolio class, as of June 30, 2015 and December 31, 2014 (in thousands):

(1) Loans past due 90 days and still accruing includes premium finance loans of $4.8 million. These loans are generally secured by obligations of insurance carriers to refund premiums on canceled 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, a reduction of the face amount of debt or forgiveness of either principal or accrued interest. As of June 30, 2015 and December 31, 2014, we had $249,000 and $1.8 million, respectively, in loans considered restructured that are not on non-accrual. These loans did not have unfunded commitments at June 30, 2015 or December 31, 2014. Of the non-accrual loans at June 30, 2015 and December 31, 2014, $28.2 million and $12.1 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, for the six months ended June 30, 2015 and 2014, loans that were restructured during 2015 and 2014 (in thousands):

June 30, 2015
	Number of Restructured Loans	Pre-Restructuring Outstanding Recorded Investment		Post-Restructuring Outstanding Recorded Investment
Commercial business loans	4	$	18,329	$	16,960

Real estate—commercial	1	$	1,441	$	1,430
Total new restructured loans in 2014	1	$	1,441	$	1,430

The restructured loans generally include terms to temporarily place loans on interest only, extend the payment terms or reduce the interest rate. We did not forgive any principal on the above loans. The restructuring of the loans did not have a significant impact on our allowance for loan losses at June 30, 2015 or 2014.

The following table provides information on how restructured loans were modified during the six months ended June 30, 2015 and 2014 (in thousands):

(6) 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 which 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

19

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.

The table below summarizes our off-balance sheet financial instruments whose contract amounts represented credit risk (in thousands):

	June 30, 2015		December 31, 2014
Commitments to extend credit	$	5,256,986	$	5,324,460
Standby letters of credit	186,483		177,808

(7) REGULATORY MATTERS

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" ("CET1"), (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.

Quantitative measures established by these regulations to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios CET1, Tier 1 and Total capital to risk-weighted assets, and of Tier 1 capital to average assets, each as defined in the regulations. Management believes, as of June 30, 2015, that the Company and the Bank met 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, CET1 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 June 30, 2015, and December 31, 2014. 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 changes may retroactively subject the Company to changes in capital ratios. Any such changes 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 adverse effect on our financial 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.

20

The table below summarizes our capital ratios:

	June 30, 2015		December 31, 2014
Company
Risk-based capital:
CET1(1)	7.43	%	7.89	%
Tier 1 capital	8.82	%	9.46	%
Total capital	11.03	%	11.83	%
Leverage	9.03	%	10.76	%

(1) December 31, 2014 ratio is unaudited.

Our mortgage finance loan volumes can increase significantly at month-end, causing a meaningful difference between ending balance and average balance for any period. At June 30, 2015, our total mortgage finance loans were $4.9 billion compared to the average for the quarter ended June 30, 2015 of $4.6 billion. As CET1, Tier 1 and total capital ratios are calculated using ending risk-weighted assets and our mortgage finance loans are 100% risk-weighted, the quarter-end fluctuation in these balances can significantly impact our reported ratios. Due to the risk profile and liquidity of this asset class, we manage capital allocated to mortgage finance loans based on changing trends in average balances and do not believe that the quarter-end balance is representative of risk characteristics that would justify higher allocations. However, we will continue to monitor our capital allocation to confirm that all capital levels remain above well-capitalized levels.

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 further limit the amount of dividends that may be paid by our bank. No dividends were declared or paid on common stock during the three and six months ended June 30, 2015 or 2014.

(8) STOCK-BASED COMPENSATION

On May 19, 2015, the Company's stockholders approved the Texas Capital Bancshares, Inc. 2015 Long-Term Incentive Plan (the "2015 Plan"), which provides for the issuance of up to 2,550,000 shares of common stock for compensation to the Company's key employees, certain key contractors and non-employee directors, subject to increase by up to approximately 751,887 shares underlying outstanding stock-settled awards granted pursuant to prior plans that may be forfeited, expire or may be canceled and available for reuse in the future pursuant to the terms of the 2015 Plan.

The fair value of our stock option and stock appreciation right (“SAR”) grants are estimated at the date of grant using the Black-Scholes option pricing model. The Black-Scholes option pricing 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 our employee stock options.

Stock-based compensation consists of SARs and RSUs granted from 2009 through June 30, 2015.

(9) 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 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.

22

Assets and liabilities measured at fair value at June 30, 2015 and December 31, 2014 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 and OREO on a nonrecurring basis as described below.

Loans

During six months ended June 30, 2015 and the year ended December 31, 2014, certain impaired loans were re-evaluated and reported at fair value through a specific allocation of the allowance for loan losses based upon the fair value of the underlying collateral. The $52.4 million reported fair value above includes impaired loans at June 30, 2015 with a carrying value of $58.6 million that were reduced by specific allowance allocations totaling $6.2 million based on collateral valuations utilizing Level 3 valuation inputs. The $23.5 million reported fair value 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 based on collateral valuations utilizing Level 3 valuation inputs. Fair values were based on third party appraisals.

OREO

Certain foreclosed assets, upon initial recognition, are valued based on third party appraisals less estimated selling costs. At June 30, 2015 and December 31, 2014, OREO had a carrying value of $609,000 and $568,000, respectively, with no specific valuation allowance. The fair value of OREO was computed based on third party appraisals, which are Level 3 valuation inputs.

23

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):

	June 30, 2015				December 31, 2014

Derivative liabilities	33,576		33,576		31,176		31,176

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

Cash and cash equivalents

The carrying amounts reported in the consolidated balance sheets 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 held for investment, 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.

Derivatives

The estimated fair value of interest rate swaps and caps 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.

24

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 certificate of deposit fair values are estimated using a discounted cash flow calculation that applies interest rates currently being offered on similar 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 values reported in the consolidated balance sheets for Federal funds purchased, customer repurchase agreements and other short-term, floating rate borrowings approximate their fair values, which are characterized as Level 2 assets in the fair value hierarchy. The fair values 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 are characterized as Level 3 liabilities in the fair value hierarchy. The subordinated notes are publicly traded and are valued based on market prices, which are characterized as Level 2 liabilities in the fair value hierarchy.

(10) DERIVATIVE FINANCIAL INSTRUMENTS

The fair value of derivative positions outstanding is included in accrued interest receivable and 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 three months ended June 30, 2015 and 2014, we entered into certain interest rate derivative positions that are 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.

25

The notional amounts and estimated fair values of interest rate derivative positions outstanding at June 30, 2015 and December 31, 2014 are presented in the following tables (in thousands):

	June 30, 2015								December 31, 2014

Net derivatives included in the consolidated balance sheets			$	33,576		$	33,576				$	31,176		$	31,176

The weighted-average receive and pay interest rates for interest rate swaps outstanding at June 30, 2015 were as follows:

	June 30, 2015 Weighted-Average Interest Rate				December 31, 2014 Weighted-Average Interest Rate
	Received		Paid		Received		Paid
Non-hedging interest rate swaps	2.81	%	4.74	%	2.79	%	4.82	%

The weighted-average strike rate for outstanding interest rate caps was 2.25% at June 30, 2015 and 1.44% at December 31, 2014.

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 $33.6 million at June 30, 2015 and approximately $31.2 million at December 31, 2014, 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 June 30, 2015 and December 31, 2014, we had $31.6 million and $30.2 million, respectively, in cash collateral pledged for these derivatives included in interest-bearing deposits.

(11) NEW ACCOUNTING PRONOUNCEMENTS

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, 2017 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. It is not expected to have a significant impact on our consolidated financial statements.

• 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.

28

• 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.

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 effectively manage 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 clientèle 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 June 30, 2015 and December 31, 2014 and results of operations for three and six months in the periods ended June 30, 2015 and 2014. This discussion should be read in conjunction with our consolidated financial statements and notes to the financial statements appearing in Part I, Item 1 of this report.

Results of Operations

Summary of Performance

We reported net income of $37.9 million and net income available to common stockholders of $35.5 million, or $0.76 per diluted common share, for the second quarter of 2015 compared to net income of $33.4 million and net income available to common stockholders of $31.0 million, or $0.71 per diluted common share, for the second quarter of 2014. Return on average common equity (“ROE”) was 10.32% and return on average assets ("ROA") was .83% for the second quarter of 2015, compared to 11.38% and 1.08%, respectively, for the second quarter of 2014. Net income and net income available to common stockholders for the six months ended June 30, 2015, totaled $73.0 million and $68.1 million, respectively, or $1.47 per diluted common share, compared to net income and net income available to common stockholders of $61.7 million and $56.8 million, respectively, or $1.30 per diluted common share, for the same period in 2014. ROE was 10.08% and ROA was .84% for the six months ended June 30, 2015 compared to 10.81% and 1.05%, respectively, for the six months ended June 30, 2014. The ROE decrease resulted from an increase in average common equity for the three and six months ended June 30, 2015, as compared to the same periods in 2014, related to the equity offering completed in the fourth quarter of 2014. The offering increased total equity by $149.7 million, and also had a dilutive effect on earnings per common share for the three and six months ended June 30, 2015 as compared to the same periods in 2014. The ROA decrease resulted from a combination of reduced yields on loans and an increase in average liquidity assets during the three and six months ended June 30, 2015 compared to the same periods of 2014.

Net income increased $4.5 million, or 14%, for the three months ended June 30, 2015, as compared to the same period in 2014. The increase was primarily the result of a $26.9 million increase in net interest income and a $2.2 million increase in non-interest income, offset by a $10.5 million increase in the provision for credit losses, a, $11.5 million increase in non-interest expense and a $2.6 million increase in income tax expense. Net income increased $11.3 million, or 18%, during the six months ended June 30, 2015, primarily as the result of a $48.6 million increase in net interest income and a $4.1 million increase in non-interest income, offset by a $16.5 million increase in the provision for credit losses, an $18.7 million increase in non-interest expense and a $6.2 million increase in income tax expense.

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

29

Net Interest Income

Net interest income was $142.3 million for the second quarter of 2015, compared to $115.4 million for the second quarter of 2014. The increase was due to an increase in average earning assets of $5.8 billion as compared to the second quarter of 2014. The increase in average earning assets included a $3.7 billion increase in average net loans and a $2.1 billion increase in average liquidity assets, offset by a $14.0 million decrease in average securities. For the quarter ended June 30, 2015, average net loans, liquidity assets and securities represented approximately 87%, 13% and less than 1%, respectively, of average earning assets compared to 98%, 2% and less than 1% for the same quarter of 2014.

Average interest-bearing liabilities for the quarter ended June 30, 2015 increased $2.4 billion from the second quarter of 2014, which included a $1.5 billion increase in interest-bearing deposits and an $899.5 million increase in other borrowings. Average demand deposits increased from $3.6 billion at June 30, 2014 to $6.8 billion at June 30, 2015. The average cost of total deposits and borrowed funds declined slightly to .16% for the second quarter of 2015 compared to .17% for the same period of 2014. The cost of interest-bearing liabilities decreased from .51% for the quarter ended June 30, 2014 to .46% for the same period of 2015.

Net interest income was $272.3 million for the six months ended June 30, 2015, compared to $223.7 million for the same period in 2014. The increase was due to an increase in average earning assets of $5.6 billion as compared to the six months ended June 30, 2014. The increase in average earning assets included a $3.6 billion increase in average net loans and a $2.0 billion increase in average liquidity assets, offset by a $15.8 million decrease in average securities. For the six months ended June 30, 2015, average net loans, liquidity assets and securities represented approximately 87%, 13% and less than 1%, respectively, of average earning assets compared to 97%, 2% and less than 1% for the same quarter of 2014.

Average interest-bearing liabilities for the six months ended June 30, 2015 increased $2.6 billion from the six months of 2014, which included a $1.7 billion increase in interest-bearing deposits, a, $889.3 million increase in other borrowings and a $29.0 million increase in long-term debt as a result of the Bank’s issuance of subordinated notes in January 2014. Average demand deposits increased from $3.5 billion at June 30, 2014 to $6.2 billion at June 30, 2015. The average cost of total deposits and borrowed funds declined slightly to .16% for the six months ended June 30, 2015 compared to .17% for the same period in 2014. The cost of interest-bearing liabilities decreased from .51% for the six months ended June 30, 2015 to .46% for the same period of 2015.

(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 and assume a 35% tax rate.

Net interest margin, which is defined as the ratio of net interest income to average earning assets, was 3.22% for the second quarter of 2015 compared to 3.87% for the second quarter of 2014. The year-over-year decrease was due to the growth in loans with lower yields, and the $2.1 billion increase in average balances of liquidity assets, which includes Federal funds sold and deposits in other banks. The cost of total deposits and borrowed funds decreased to .16% for the second quarter of 2015 compared to .17% for the second quarter of 2014. The spread on total earning assets, net of the cost of deposits and borrowed funds, was 3.31% for the second quarter of 2015 compared to 4.01% for the second quarter of 2014. The decrease resulted from the significant increase in liquidity assets coupled with a 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, decreased to .24% for the second quarter of 2015 compared to .31% for the second quarter of 2014. The average interest rate on long-term debt for the second quarter of 2015 was 4.84% compared to 4.88% for the same period of 2014.

Non-interest Income

The components of non-interest income were as follows (in thousands):

	Three months ended June 30,				Six months ended June 30,
	2015		2014		2015		2014
Service charges on deposit accounts	$	2,149	$	1,764	$	4,243	$	3,460

Total non-interest income	$	12,771	$	10,533	$	25,038	$	20,889

31

Non-interest income increased $2.2 million during the three months ended June 30, 2015 compared to the same period of 2014. This increase was primarily due to a $1.9 million increase in brokered loan fees as a result of an increase in mortgage finance volumes during the second quarter of 2015. Swap fees increased $625,000 during the three months ended June 30, 2015 compared to the same period of 2014. These fees fluctuate from quarter to quarter 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. Service charges increased $385,000 during the three months ended June 30, 2015 compared to the same period of 2014 as a result of an increase in deposit balances year-over-year. Offsetting these increases was a $692,000 decrease 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 $4.1 million during the six months ended June 30, 2015 compared to the same period of 2014. This increase was primarily due to a $3.3 million increase in brokered loan fees as a result of an increase in mortgage finance volumes during the first six months of 2015. Swap fee income increased $1.4 million during the six months ended June 30, 2015 compared to the same period of 2014. These fees fluctuate from quarter to quarter 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. Service charges increased $783,000 during the six months ended June 30, 2015 compared to the same period of 2014 as a result of an increase in deposit balances year-over-year. Offsetting these increases was a $1.2 million decrease 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.

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. In order to achieve 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.

(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 second quarter of 2015 increased $11.5 million, or 16%, to $81.3 million from $69.8 million in the second quarter of 2014. The increase is primarily attributable to an $8.3 million increase in salaries and employee benefits expense due to general business growth and as we respond to continued regulatory changes and strategic initiatives.

Net occupancy expense for the three months ended June 30, 2015 increased $735,000 as a result of general business growth and continued build-out needed to support that growth.

Legal and professional expense for three months ended June 30, 2015 decreased $1.6 million compared to the same quarter of 2014. Our legal and professional expense will continue to fluctuate and could increase in the future due to general business growth and as we respond to continued regulatory changes and strategic initiatives.

Analysis of Financial Condition

Loan Portfolio

Loans were as follows as of the dates indicated (in thousands):

Allowance for loan losses	(118,770		)	(100,954		)
Total loans held for investment, net	$	15,910,970		$	14,156,058

Total loans net of allowance for loan losses at June 30, 2015 increased $1.8 billion from December 31, 2014 to $15.9 billion. 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. Consumer loans generally have represented 1% or less of the portfolio. Mortgage finance loans relate to our mortgage warehouse lending operations in which we invest in mortgage loan ownership interests that are typically sold within 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 June 30, 2015, we had $1.7 billion in syndicated loans, $347.3 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. As of June 30, 2015, $58.6 million of our syndicated loans were on non-accrual.

33

Portfolio Geographic Concentration

As of June 30, 2015, a substantial 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.

Summary of Loan Loss Experience

The provision for credit losses is a charge to earnings to maintain the reserve for loan losses at a level consistent with management’s assessment of the loan portfolio in light of current economic conditions and market trends. We recorded a provision of $14.5 million during the second quarter of 2015 compared to $11.0 million in the first quarter of 2014 and $4.0 million in the second quarter of 2014. The provision was driven by the application of our methodology. The increase was primarily related to the growth in traditional loans held for investment, excluding mortgage finance loans, as well as a change in applied risk weights which are based in part on historical loss experience as well as changes in the composition of our pass-rated loan portfolio.

We continue to maintain 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 June 30, 2015 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.

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 credit grades, and then further segregated by product types to recognize differing risk profiles among categories. 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 to differ from past experience. In addition, the reserve reflects the results of reviews performed by the Company's independent Credit Review function as reflected in their confirmations of assigned credit grades within the portfolio. The Credit Review function reports to the Credit Risk Committee of the Company's board of directors with administrative oversight from the Company's Chief Risk Officer. 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 Company'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 the amount and frequency of losses attributable to issues not specifically addressed or included in the determination and application of the allowance allocation percentages. We believe the allowance is 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 the 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 combined reserve for credit losses, which includes a liability for losses on unfunded commitments, totaled $126.7 million at June 30, 2015, $108.0 million at December 31, 2014 and $96.7 million at June 30, 2014. The total reserve percentage increased to 1.14% at June 30, 2015 from 1.06% and 1.06% of loans excluding mortgage finance loans at December 31, 2014 and June 30, 2014, respectively.

At June 30, 2015, 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) Interim period ratios are annualized.

(2) At June 30, 2015, December 31, 2014 and June 30, 2014, loans past due 90 days and still accruing include premium finance loans of $4.8 million, $3.7 million and $4.6 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) We did not have a valuation allowance recorded against the OREO balance at June 30, 2015, December 31, 2014 or June 30, 2014.

(4) As of June 30, 2015, December 31, 2014 and June 30, 2014, non-accrual loans included $28.2 million, $12.1 million and $16.2 million, respectively, in loans that met the criteria for restructured.

Non-performing Assets

Non-performing assets include non-accrual loans and leases and repossessed assets. The table below summarizes our non-accrual loans by type and OREO (in thousands):

	June 30, 2015		December 31, 2014		June 30, 2014

The table below summarizes the non-accrual loans as segregated by loan type and type of property securing the credit as of June 30, 2015 (in thousands):

Non-accrual loans:
Commercial
Lines of credit secured by the following:
Oil and gas properties	$	37,984
Assets of the borrowers	53,206
Other	875
Total commercial	92,065

Unimproved land and/or undeveloped lots	16,749
Real estate

Other	1,079
Total real estate	7,669
Leases (commercial leases primarily secured by assets of the lessor)	6,437
Total non-accrual loans	$	122,920

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

37

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. 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.

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 June 30, 2015 and December 31, 2014, we had $15.2 million and $16.3 million, respectively, in loans of this type which were not included in either non-accrual or 90 days past due categories.

The following table summarizes the assets held in OREO at June 30, 2015 (in thousands):

Undeveloped land and residential lots	$	487
Other	122
Total OREO	$	609

When foreclosure occurs, fair value, which is generally based on appraised values, may result in partial charge-off of a loan upon taking the collateral, and so long as the collateral is retained, subsequent 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 three or six months ended June 30, 2015 or June 30, 2014.

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 year ended December 31, 2014 and for the six months ended June 30, 2015 our principal source of funding has been our customer deposits, supplemented by our borrowings, primarily short-term Federal funds purchased and FHLB borrowings used to fund mortgage finance assets.

Our liquidity needs for support of growth in loans held for investment 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, 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 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, compared to customer deposits. The following table summarizes our period-end and average year-to-date core customer deposits and brokered deposits (in millions):

	June 30, 2015			December 31, 2014			June 30, 2014
Deposits from core customers	$	12,623.2		$	10,900.0		$	8,642.9
Deposits from core customers as a percent of total deposits	89.0		%	86.0		%	80.4		%

Average deposits from core customers as a percent of total quarterly average deposits(1)	88.3		%	84.1		%	83.0		%
Average relationship brokered deposits(1)	$	1,644.4		$	1,709.8		$	1,618.0
Average relationship brokered deposits as a percent of total quarterly average deposits(1)	11.7		%	15.7		%	16.6		%
Average traditional brokered deposits(1)	$	—		$	20.7		$	41.7
Average traditional brokered deposits as a percent of total quarterly average deposits(1)	—		%	0.2		%	0.4		%

(1) Annual averages presented for December 31, 2014.

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 June 30, 2015 increased by $1.5 billion from December 31, 2014 and increased $3.9 billion from June 30, 2014.

39

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 assets, due to their liquidity, short duration and interest spreads available. These borrowing sources typically 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 short-term borrowings as of June 30, 2015 (in thousands):

Federal funds purchased	$	79,088
Repurchase agreements	29,919
FHLB borrowings	1,400,000
Total short-term borrowings	$	1,509,007
Maximum short-term borrowings outstanding at any month-end during the year	$	1,986,214

The following table summarizes our other borrowing capacities in excess of balances outstanding at June 30, 2015 (in thousands):

FHLB borrowing capacity relating to loans	$	4,118,100
FHLB borrowing capacity relating to securities	1,523
Total FHLB borrowing capacity	$	4,119,623
Unused Federal funds lines available from commercial banks	$	1,280,000

The following table summarizes our long-term borrowings as of June 30, 2015 (in thousands):

Subordinated notes	$	286,000
Trust preferred subordinated debentures	113,406
Total long-term borrowings	$	399,406

At June 30, 2015, we had a revolving, non-amortizing line of credit with $100.0 million of unused capacity. This line of credit matures on 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. At June 30, 2015 and December 31, 2014, no borrowings were outstanding.

Our equity capital, including $150 million in preferred stock, averaged $1.5 billion for the six months ended June 30, 2015, as compared to $1.2 billion for the same period in 2014. 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.

As of June 30, 2015 our capital ratios were above the levels required to be well capitalized. We believe that our earnings, periodic capital raising transactions, and the addition of loan and deposit relationships, will allow us to continue to grow organically.

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, we believe the policy described below meets the SEC’s definition of a critical accounting policy.

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 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 reserve, 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 4 – 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.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES 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 2014. 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 expect the current decline in petroleum and natural gas 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 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. The CPC establishes 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 June 30, 2015, 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.

The table above sets forth the balances as of June 30, 2015 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 loan and deposit 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 rates; the prime lending rate and 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. We believe these are our primary interest rate exposures. We are not currently 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 and the first six months of 2015, 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.

43

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 and 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				Anticipated Impact Over the Next Twelve Months as Compared to Most Likely Scenario
	100 bp Increase		200 bp Increase		100 bp Increase		200 bp Increase
	June 30, 2015				June 30, 2014
Change in net interest income	$	84,883	$	178,313	$	54,031	$	119,028

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 may 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.

c.    Notwithstanding the foregoing and except as otherwise provided in Section 5 below and regardless of whether the performance criteria set forth in Exhibit A have been achieved, in the event that a Change in Control occurs and on or after the date of the Change in Control, the Participant incurs a Termination of Service by the Company (or by its successor following the Change in Control) without Cause (as defined in Section 3.d. below) or by the Participant for Good Reason (as defined in Section 3.f. below), then 100% of the Unvested Units shall immediately become Vested Units upon such termination.

d.    For purposes hereof, “Cause” shall have the meaning set forth in the Participant’s employment agreement with the Company.

e.    For purposes hereof, “Change in Control” shall have the meaning set forth in the Plan, provided that such event is a “change in control” within the meaning of Section 409A of the Code, and the regulations and other applicable guidance issued thereunder.

f.    For purposes hereof, “Good Reason” shall have the meaning set forth in the Participant’s employment agreement with the Company.

g.    Notwithstanding anything to the contrary contained herein, if at any time after the date the Participant reaches age 65 plus twelve (12) years of service with the Company the Participant incurs a Termination of Service with the Board’s consent (other than a Termination of Service for Cause or without Good Reason), then:

(i)    A prorated portion of the Time-Based Units shall become Vested Units based on the number of full years between the Date of Grant and the Participant’s Termination of Service (calculated by multiplying the total number of Time-Based Units by a fraction, the numerator of which is the number of full years the Participant has been employed since the Date of Grant and the denominator of which is three), provided that such Vested Units shall remain subject to the payout provisions of Section 4; and

(ii)    The Performance Units shall not be forfeited upon the Participant’s Termination of Service and instead, such Performance Units shall continue to be subject to the vesting and payout provisions set forth in Exhibit A hereto as if the Participant had remained employed by the Company.

4.    Delivery of Common Stock. The Vested Units shall be converted into the number of whole shares of Common Stock equal to the number of Vested Units and the Company shall electronically register such shares of Common Stock in the Participant’s name (or in the name of his or her estate or beneficiary) or deliver certificates for the such shares of Common Stock to the Participant in accordance with the following schedule:

a.    In 2018, (A) with respect to the Performance Units, as soon as administratively practicable following determination by the Committee that the vesting conditions set forth in Exhibit A have been achieved; and (B) with respect to the Time-Based Units, on June 1, 2018; or

b.    If earlier, the date of the Participant’s Termination of Service without Cause or with Good Reason on or after a Change in Control.

To the extent an Awarded Unit does not vest in accordance with the provisions of Section 3 hereof by June 1, 2018, such Awarded Unit shall be forfeited and no shares of Common Stock shall be delivered with respect to such forfeited Awarded Unit.

5.    Forfeiture and Disgorgement.

a.    Notwithstanding any provisions in this Agreement to the contrary, in the event the Participant violates the provisions of Section 5.b. or the provisions of any agreement between the Company (or any of its Subsidiaries) that contains confidentiality, non-solicitation or other protective or restrictive covenant provisions, then:

(i)    the Awarded Units shall immediately cease to vest as of the date of such violation;

(ii)    any shares of Common Stock that had not been registered (or delivered) with respect to Awarded Units shall be immediately forfeited and this Agreement (other than the provisions of this Section 5) will be terminated on the date of such violation; and

(iii)    any shares of Common Stock (less any taxes paid by the Participant on such shares of Common Stock) that had been delivered to the Participant (or registered in the Participant’s name) with respect to any Vested Units shall be immediately returned to the Company by the Participant.

The Company must deliver written notice of its intent to enforce the provisions of this Section 5.a. at least fifteen (15) days prior to the date it intends to enforce the terms of Sections 5.a.(i) and (ii). Both the Company and the Participant agree that upon delivery of written notice under this Section 5.a., neither party will enter into any transaction that will affect the other party’s interests in the cash subject to dispute until the expiration of the fifteen (15) day notice period.

The provisions of this Section 5 (including, without limitation, the provisions of this Section 5.a. and the provisions of Section 5.b. below) only shall apply to the Awarded Units for the period beginning on the Date of Grant and ending on the earlier of (i) the one year (or, in the event the Awarded Units vest in accordance with Section 3.g. above, the four year) anniversary of the date the Awarded Units become vested in accordance with the provisions of Section 3 above (regardless of whether the Agreement terminates or expires prior to such date), or (ii) if a Change in Control occurs, the date of the Participant’s Termination of Service either by the Company without Cause or by the Participant with Good Reason.

b.    By execution of this Agreement, the Participant, either individually or as a principal, partner, stockholder, manager, agent, consultant, contractor, employee, lender, investor, volunteer or as a director or officer of any corporation or association, or in any other manner or capacity whatsoever, agrees to the following:

(i)    Confidential Information. The Participant acknowledges that the Company has developed and will continue to develop unique concepts, lending practices, sales presentations, marketing programs, marketing strategies, business practices, methods of operation, pricing information, cost information, trademarks, licenses, technical information, proprietary information, computer software programs, computer tapes and disks concerning its operations systems, customer lists, customer leads, customer loan and financial information, documents identifying past, present and future customers, customer profiles and preference data, hiring and training methods, investment policies, financial and other confidential, proprietary and/or trade secret information concerning the Company’s operations and expansion plans (“Confidential Information”). The Confidential Information includes, without limitation, information about the Company’s business,

3

proprietary, and technical information that is not known to others and could have economic value to others if improperly disclosed. Confidential Information also means any information the Company discloses to the Participant, either directly or indirectly, in writing, orally or by inspection of tangible objects, including, without limitation, information and technical data contained in the Company’s manuals, booklets, publications and materials, equipment of every kind and character, as well as documents, prototypes, samples, prospects, inventions, product ideas, know how, processes, plans (including, without limitation, marketing plans and strategies), specifications, designs, techniques, technology, formulas, software, improvements, forecasts, and research. Confidential Information does not include any information that is available to the public or, upon reasonable investigation, is ascertainable in the public domain or information generally known outside of the Company. The Participant’s obligations under this Section 5 regarding specific Confidential Information shall cease when that specific portion of the Confidential Information becomes publicly known, in its entirety and without combining portions of such information obtained separately.

(ii)    Access to and Agreement Not To Disclose Confidential Information. During Participant’s Company employment, the Company agrees to provide the Participant with some or all of the Company’s Confidential Information to which the Participant has not had previous access or knowledge. By executing this Agreement, the Participant agrees that the Confidential Information constitutes valuable, special and unique assets of the Company, developed at the Company’s great expense, the unauthorized use or disclosure of which would cause irreparable harm to the Company. The Participant understands and acknowledges that the Company is engaged in a specialized and competitive industry; that the Company relies heavily on information, data, programs, and processes it has developed and acquired; and that competitors can reap potential or real economic benefits from the possession of the Confidential Information that is otherwise not available to its competitors. The Participant understands and acknowledges, therefore, that the protection of the Company’s Confidential Information constitutes the Company’s legitimate business interest. The Participant acknowledges that the Confidential Information is the Company’s exclusive property, and the Participant will hold the Confidential Information in trust and solely for the Company’s benefit. The Participant further acknowledges that the Confidential Information includes “trade secrets” under Texas law and, in addition to the other protections provided in this Agreement, all trade secrets will be accorded the protection and benefits under Texas law and any other applicable law. The Participant waives any requirement that the Company submit proof of any trade secret’s economic value or post a bond or other security should the need arise.

In exchange for the Company’s promise to provide the Participant with some or all of the Company’s Confidential Information to which the Participant has not previously had access or knowledge, the Participant agrees that he or she will not, either during the period of the Participant’s employment with the Company or at any time thereafter, use or rely upon for the Participant’s benefit or the benefit of another, or disclose, disseminate, or distribute to anyone, including, without limitation, any individual, person, firm, corporation, or other entity, or publish, or use for any purpose, any of the Confidential Information (whether acquired, learned, obtained, or developed by the Participant alone or in conjunction with others), except (A) as properly required in the ordinary course of the Company’s business or as the Company directs and authorizes; (B) as required by applicable law (if, to the extent reasonable and practicable, reasonable prior notice of such disclosure is given to the Company); or (C) to the extent such information is available to or known by the public (other than as a result of disclosure in violation of this Agreement). The Participant agrees

4

that he or she will take all reasonable measures to protect the secrecy of and avoid unauthorized disclosure and unauthorized use of the Confidential Information. The Participant also agrees to notify the Company immediately in the event of any unauthorized use, reliance upon or disclosure of the Company’s Confidential Information of which the Participant is aware.

(iii)    Use of Confidential Information During Employment. The Participant further agrees that in the course of his or her employment by the Company, the Participant will not remove from any office of the Company any documents, electronically stored information, or related items that contain Confidential Information, including, without limitation, computer discs, recordings, or other storage or archival systems or devices, including copies, except as may be required in the performance of the Participant’s duties as an employee of the Company. The Participant also agrees that he or she will not place or save any Confidential Information on any computer or electronic storage system that is not the Company’s property, except to perform work for the Company. All Confidential Information, and all memoranda, notes, records, drawings, documents, or other writings whatsoever made, compiled, acquired, or received by the Participant at any time during his or her employment, including during the term of this Agreement, arising out of, in connection with, or related to any activity or business of the Company, including, without limitation, the customers, vendors, third parties, or others with whom the Company has a business relationship, the arrangements of the Company with such parties, and the pricing and expansion policies and strategy of the Company, are, and shall continue to be, the Company’s sole and exclusive property.

(iv)    Protective Covenants. The Participant agrees that to protect the Company’s Confidential Information, and in consideration for the equity compensation in this Agreement, it is necessary to enter into the following protective covenants, which are ancillary to the enforceable promises between the Company and the Participant in the other Agreement Sections. During the Participant’s employment with the Company, and for a one-year period (or, in the event the Awarded Units vest in accordance with Section 3.g. above, the four-year period) after the date the Participant’s employment is terminated by the Company for any reason, or if the Participant resigns for any reason, the Participant shall not, without the Company’s prior written consent, directly or indirectly: (A) compete for or solicit business for or on behalf of any person or business entity operating a state or national bank or company providing similar services with a place of business in the State of Texas; (B) own, operate, participate in, undertake any employment with, or have any interest in any entity with a place of business in the State of Texas related to the operation of a state or national bank or company providing similar services, except that the Participant may own publicly traded stock for investment purposes only in any company in which the Participant owns less than 5% of the voting equity; or (C) use or rely upon in any competition, solicitation, or marketing effort any Confidential Information.

The Participant also acknowledges that the geographic boundaries, scope of prohibited activities, and the duration of the provisions in the Protective Covenants are reasonable and are no broader than are necessary to protect the Company’s legitimate business interests. The Protective Covenants shall survive the termination of the Participant’s employment and can be revoked or modified only by a writing signed by the parties that specifically states an intent to revoke or modify this provision. The Participant acknowledges that the Company would not provide him or her with access to its Confidential Information but for his or her covenants or promises contained in this Section 5.b. The Participant further agrees that during the protective covenant term, he or she shall

5

immediately notify the Company in writing of any employment, work, or business he or she undertakes with or on behalf of any person (including himself or herself) or entity.

(v)    No Solicitation of Employees/Customers. The Participant agrees that the no-employee solicitation covenant in this Section 5.b.(v) constitutes a reasonable and appropriate means, consistent with the best interests of both the Participant and the Company, to protect the Company’s interests in providing valuable equity compensation to the Participant and in preventing the loss or disclosure of the Company’s Confidential Information. As an inducement for the Company’s agreement to provide the Participant the equity compensation in this Agreement, and to provide the Participant with the Company’s Confidential Information, the Participant agrees that during the Participant’s employment, and for a period of one (1) year following the termination or resignation of the Participant’s employment, for whatever reason, the Participant will not, alone or in combination with any individual, partner(s), company, corporation, or other entity or business with which he is in any way affiliated, including, without limitation, any partner, limited partner, member, director, officer, shareholder, employee, or agent of any such entity, recruit, solicit, request, induce or attempt to influence, directly or indirectly, any employee of the Company to resign or terminate employment with the Company. The Participant agrees that for a period of one year (or, in the event the Awarded Units vest in accordance with Section 3.g. above, four years) following the termination or resignation of his employment, for whatever reason, whether involuntary or voluntary, he shall not, directly or indirectly, as an owner, stockholder, director, employee, partner, agent, broker, consultant or other participant solicit a customer or prospective customer, or accept any business from a customer or prospective customer with whom he or she has done business or with whom he or she has had contact during the last twelve (12) months of the Participant’s employment with the Company.

(vi)    Definition Related to No-Solicitation of Employee Provision. In Section 5.b.(v), “Employee” means any employee on the Company’s payroll during the Protective Covenant time period specified in Section 5.b.(v).

(vii)    Return of Documents. In the event of the Participant’s termination or resignation of his or her employment with the Company for any reason, the Participant will deliver to the Company all non-personal documents and data of any nature, and in whatever medium, concerning the Participant’s employment with the Company or any of its Subsidiaries. The Participant agrees that he or she will not take with him or her any of the Company’s property, documents, or data of any description or any reproduction thereof, including summaries or notes regarding same, or any documents containing or relating to any of the Company’s Confidential Information.

(viii)    Injunctive Relief. The Participant acknowledges and agrees that the Participant’s obligations, covenants, and agreements in Sections 5.b.(i)-(vii) concern special, unique and extraordinary matters and that a violation of any of the terms of these agreements, covenants or obligations will cause the Company irreparable injury for which adequate remedies at law are not available. Therefore, the Participant agrees that the Company, in addition to any amounts that the Company is entitled to pursuant to Section 5.a. above, will be entitled to an injunction, restraining order, or all other equitable relief as a court of competent jurisdiction may deem necessary or appropriate to restrain the Participant from committing any violation of the agreements, covenants or obligations referred to in Sections 5.b.(i)-(vii).

6.    Who May Receive Common Stock with Respect to Vested Units. During the lifetime of the

6

Participant, the Common Stock received upon conversion of the Vested Units may only be received by the Participant or his or her legal representative. If the Participant dies prior to the date his or her Awarded Units are converted into shares of Common Stock as described in Section 4 above, the Common Stock relating to such converted Awarded Units may be received by any individual who is entitled to receive the property of the Participant pursuant to the applicable laws of descent and distribution.

7.    Common Stock Subject Ownership Guidelines. The Participant acknowledges, understands and agrees that any Common Stock delivered to the Participant (or registered in the Participant’s name) pursuant to this Agreement shall be subject to the Common Stock ownership guidelines as adopted by the Committee and in effect from time to time, and that the Participant may be required to hold such Common Stock until the Participant has met the requirements of such ownership guidelines. The Participant further acknowledges, understands and agrees that the Committee retains the right to modify the Company’s Common Stock ownership guidelines at any time.

8.    Rights as Stockholder. The Participant will have no rights as a stockholder with respect to the Awarded Units until the issuance of a certificate or certificates to the Participant or the registration of such shares of Common Stock in the Participant’s name. The Awarded Units shall be subject to the terms and conditions of this Agreement.

9.    No Fractional Shares. Awarded Units may be converted only with respect to full shares, and no fractional share of Common Stock shall be issued.

10.    Non-assignability. The Awarded Units are not assignable or transferable by the Participant except by will or by the laws of descent and distribution.

11.    The Participant’s Acknowledgments. The Participant acknowledges receipt of a copy of the Plan, which is annexed hereto, and represents that he or she is familiar with the terms and provisions thereof, and hereby accepts the Awarded Units subject to all the terms and provisions thereof. The Participant hereby agrees to accept as binding, conclusive, and final all decisions or interpretations of the Committee or the Board, as appropriate, upon any questions arising under the Plan or this Agreement.

12.    Adjustment of Number of Awarded Units and Related Matters. The number of shares of Common Stock covered by the Awarded Units shall be subject to adjustment in accordance with Articles 11-13 of the Plan.

13.    Execution of Documents. The Participant, by his or her execution of this Agreement, hereby agrees to execute any documents requested by the Company in connection with the payment of any amount in connection with the Awarded Units pursuant to this Agreement.    

14.Remedies. Except as otherwise provided in Section 5 in this Agreement, each of the parties to this Agreement will be entitled to enforce its rights under this Agreement specifically, to recover damages and costs (including reasonable attorneys’ fees) caused by any breach of any provision of this Agreement, and to exercise all other rights existing in the party’s favor. The parties hereto agree and acknowledge that money damages may not be an adequate remedy for any breach of the provisions of this Agreement and that any party in its, his or her sole discretion may apply to any court of law or equity of competent jurisdiction (without posting any bond or deposit) for specific performance and/or other injunctive relief in order to enforce or prevent any violations of the provisions of this Agreement. The remedies for any violation of Section 5 above are limited to the forfeiture, disgorgement, and injunction remedies specified in Sections 5.a. and b.(viii). and are subject to the time-limitations set forth in Section 5.a. above. The remedies described in this Section 14 do not apply to Section 5.

7

15.    The Participant’s Representations. Notwithstanding any of the provisions hereof, the Participant hereby agrees that the Company will not be obligated to register any shares of Common Stock in the Participant’s name or issue any shares of Common Stock to the Participant hereunder, if the issuance of such shares shall constitute a violation by the Participant or the Company of any provision of any law or regulation of any governmental authority. Any determination by the Company under this Section 15 shall be final, binding, and conclusive. The obligations of the Company and the rights of the Participant are subject to all applicable laws, rules and regulations.

16.    Investment Representation. Unless the shares of Common Stock are issued to the Participant in a transaction registered under applicable federal and state securities laws, by his execution hereof, the Participant represents and warrants to the Company that all Common Stock which may be acquired hereunder will be acquired by the Participant for investment purposes for his own account and not with any intent for resale or distribution in violation of federal or states securities laws, all certificates issued with respect to the Common Stock shall bear an appropriate restrictive investment legend and shall be held indefinitely, unless they are subsequently registered under the applicable federal and state securities laws or the Participant obtains an opinion of counsel, in form and substance satisfactory to the Company and its counsel, that such registration is not required.

17.    Law Governing. This Agreement shall be governed by, construed, and enforced in accordance with the laws of the State of Texas (excluding any conflict of laws rule or principle of Texas law that might refer the governance, construction, or interpretation of this agreement to the laws of another state).

20.    Covenants and Agreements as Independent Agreements. Each of the covenants and agreements set forth in this Agreement shall be construed as a covenant and agreement independent of any other provision of this Agreement. The existence of any claim or cause of action of the Participant against the Company, whether predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement by the Company of the covenants and agreements that are set forth in this Agreement.

21.    Entire Agreement. This Agreement, together with the Plan, supersede any and all other prior understandings and agreements, either oral or in writing, between the parties with respect to the subject matter in this Agreement and constitute the only agreements between the parties with respect to the subject matter in this Agreement.

b.    A termination of employment shall not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment of any amounts or benefits upon or following a termination of employment unless such termination is also a “separation from service” (within the meaning of Section 409A of the Code).

c.    It is intended that this Agreement comply with the provisions of Section 409A of the Code so as to not subject the Participant to the payment of additional interest and taxes under Section 409A of the Code, and in furtherance of this intent, this Agreement shall be interpreted, operated and administered in a manner consistent with these intentions.

OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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.

The consolidated interim financial statements have been prepared without audit. Certain information and footnote disclosures presented in accordance with GAAP have been condensed or omitted. In the opinion of management, the interim financial statements include all normal and recurring adjustments and the disclosures made are adequate to make the interim financial information not misleading. The consolidated financial statements have been prepared in accordance with GAAP for interim financial information and the instructions to Form 10-Q adopted by the Securities and Exchange Commission (“SEC”). Accordingly, the financial statements do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with our consolidated financial statements, and notes thereto, for the year ended December 31, 2014, included in our Annual Report on Form 10-K filed with the SEC on February 19, 2015 (the “2014 Form 10-K”). Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for a full year or any future period.

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.

DERIVATIVE FINANCIAL INSTRUMENTS

Derivative Instruments and Hedging Activities Disclosure [Abstract]

DERIVATIVE FINANCIAL INSTRUMENTS

DERIVATIVE FINANCIAL INSTRUMENTS

The fair value of derivative positions outstanding is included in accrued interest receivable and 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 three months ended June 30, 2015 and 2014, we entered into certain interest rate derivative positions that are 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 June 30, 2015 and December 31, 2014 are presented in the following tables (in thousands):

	June 30, 2015								December 31, 2014

Non-hedging interest rate swaps	2.81	%	4.74	%	2.79	%	4.82	%

The weighted-average strike rate for outstanding interest rate caps was 2.25% at June 30, 2015 and 1.44% at December 31, 2014.

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 $33.6 million at June 30, 2015 and approximately $31.2 million at December 31, 2014, 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 June 30, 2015 and December 31, 2014, we had $31.6 million and $30.2 million, respectively, in cash collateral pledged for these derivatives included in interest-bearing deposits.

NEW ACCOUNTING PRONOUNCEMENTS

NEW ACCOUNTING PRONOUNCEMENTS

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, 2017 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. It is not expected to have a significant impact on our consolidated financial statements.

Commercial Loans and Leases. Our commercial loan and lease 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 transactional 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 interests 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. Balances as of June 30, 2015 and December 31, 2014 are stated net of $541.0 million and $358.3 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, the impact of the inability of potential purchasers and lessees to obtain financing and a lack of transactions at comparable values.

At June 30, 2015 and December 31, 2014, we had a blanket floating lien on certain real estate-secured loans, mortgage finance loans and certain securities used as collateral for Federal Home Loan Bank (“FHLB”) borrowings.

Portfolio Geographic Concentration

As of June 30, 2015, a substantial 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 appropriateness of the allowance for loan losses. Management believes the allowance for loan losses is appropriate to cover probable losses inherent in the loan portfolio at each balance sheet date.

Summary of Loan Loss Experience

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 credit-worthiness 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 the current 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 insufficiently protected by the current 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, on the basis of currently existing facts, conditions and values, 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 for such things as general economic conditions and 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 reflects the results of reviews performed by the Company's independent Credit Review function as reflected in their confirmations of assigned credit grades within the portfolio. The Credit Review function reports to the Credit Risk Committee of the Company's board of directors with administrative oversight from the Company's Chief Risk Officer. 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 Company'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 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. We consider the allowance to be appropriate, given management’s assessment of probable 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 appropriateness, 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 appropriateness relies primarily on our loss history. The review of the reserve appropriateness 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 June 30, 2015 and December 31, 2014 (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 June 30, 2015 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. As of June 30, 2015, $904,100 of our non-accrual loans were earning on a cash basis compared to $310,000 at December 31, 2014. 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 ASC 310 Receivables ("ASC 310"), we have also included all restructured loans in our impaired loan totals. The following tables detail our impaired loans, by portfolio class, as of June 30, 2015 and December 31, 2014 (in thousands):

(1) Loans past due 90 days and still accruing includes premium finance loans of $4.8 million. These loans are generally secured by obligations of insurance carriers to refund premiums on canceled 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, a reduction of the face amount of debt or forgiveness of either principal or accrued interest. As of June 30, 2015 and December 31, 2014, we had $249,000 and $1.8 million, respectively, in loans considered restructured that are not on non-accrual. These loans did not have unfunded commitments at June 30, 2015 or December 31, 2014. Of the non-accrual loans at June 30, 2015 and December 31, 2014, $28.2 million and $12.1 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, for the six months ended June 30, 2015 and 2014, loans that were restructured during 2015 and 2014 (in thousands):

June 30, 2015
	Number of Restructured Loans	Pre-Restructuring Outstanding Recorded Investment		Post-Restructuring Outstanding Recorded Investment
Commercial business loans	4	$	18,329	$	16,960
Total new restructured loans in 2015	4	$	18,329	$	16,960

Real estate—commercial	1	$	1,441	$	1,430
Total new restructured loans in 2014	1	$	1,441	$	1,430

The restructured loans generally include terms to temporarily place loans on interest only, extend the payment terms or reduce the interest rate. We did not forgive any principal on the above loans. The restructuring of the loans did not have a significant impact on our allowance for loan losses at June 30, 2015 or 2014.

The following table provides information on how restructured loans were modified during the six months ended June 30, 2015 and 2014 (in thousands):

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.

The consolidated interim financial statements have been prepared without audit. Certain information and footnote disclosures presented in accordance with GAAP have been condensed or omitted. In the opinion of management, the interim financial statements include all normal and recurring adjustments and the disclosures made are adequate to make the interim financial information not misleading. The consolidated financial statements have been prepared in accordance with GAAP for interim financial information and the instructions to Form 10-Q adopted by the Securities and Exchange Commission (“SEC”). Accordingly, the financial statements do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with our consolidated financial statements, and notes thereto, for the year ended December 31, 2014, included in our Annual Report on Form 10-K filed with the SEC on February 19, 2015 (the “2014 Form 10-K”). Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for a full year or any future period.

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.

STOCK-BASED COMPENSATION

Compensation Related Costs [Abstract]

STOCK-BASED COMPENSATION

STOCK-BASED COMPENSATION

On May 19, 2015, the Company's stockholders approved the Texas Capital Bancshares, Inc. 2015 Long-Term Incentive Plan (the "2015 Plan"), which provides for the issuance of up to 2,550,000 shares of common stock for compensation to the Company's key employees, certain key contractors and non-employee directors, subject to increase by up to approximately 751,887 shares underlying outstanding stock-settled awards granted pursuant to prior plans that may be forfeited, expire or may be canceled and available for reuse in the future pursuant to the terms of the 2015 Plan.

The fair value of our stock option and stock appreciation right (“SAR”) grants are estimated at the date of grant using the Black-Scholes option pricing model. The Black-Scholes option pricing 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 our employee stock options.

Stock-based compensation consists of SARs and RSUs granted from 2009 through June 30, 2015.

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 which 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.

The table below summarizes our off-balance sheet financial instruments whose contract amounts represented credit risk (in thousands):

	June 30, 2015		December 31, 2014

REGULATORY MATTERS

Regulatory Capital Requirements [Abstract]

REGULATORY MATTERS

REGULATORY MATTERS

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" ("CET1"), (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.

Quantitative measures established by these regulations to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios CET1, Tier 1 and Total capital to risk-weighted assets, and of Tier 1 capital to average assets, each as defined in the regulations. Management believes, as of June 30, 2015, that the Company and the Bank met 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, CET1 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 June 30, 2015, and December 31, 2014. 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 changes may retroactively subject the Company to changes in capital ratios. Any such changes 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 adverse effect on our financial 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:

	June 30, 2015		December 31, 2014
Company
Risk-based capital:
CET1(1)	7.43	%	7.89	%
Tier 1 capital	8.82	%	9.46	%
Total capital	11.03	%	11.83	%
Leverage	9.03	%	10.76	%

(1) December 31, 2014 ratio is unaudited.

Our mortgage finance loan volumes can increase significantly at month-end, causing a meaningful difference between ending balance and average balance for any period. At June 30, 2015, our total mortgage finance loans were $4.9 billion compared to the average for the quarter ended June 30, 2015 of $4.6 billion. As CET1, Tier 1 and total capital ratios are calculated using ending risk-weighted assets and our mortgage finance loans are 100% risk-weighted, the quarter-end fluctuation in these balances can significantly impact our reported ratios. Due to the risk profile and liquidity of this asset class, we manage capital allocated to mortgage finance loans based on changing trends in average balances and do not believe that the quarter-end balance is representative of risk characteristics that would justify higher allocations. However, we will continue to monitor our capital allocation to confirm that all capital levels remain above well-capitalized levels.

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 further limit the amount of dividends that may be paid by our bank. No dividends were declared or paid on common stock during the three and six months ended June 30, 2015 or 2014.

FAIR VALUE DISCLOSURES

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 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 June 30, 2015 and December 31, 2014 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 and OREO on a nonrecurring basis as described below.

Loans

During six months ended June 30, 2015 and the year ended December 31, 2014, certain impaired loans were re-evaluated and reported at fair value through a specific allocation of the allowance for loan losses based upon the fair value of the underlying collateral. The $52.4 million reported fair value above includes impaired loans at June 30, 2015 with a carrying value of $58.6 million that were reduced by specific allowance allocations totaling $6.2 million based on collateral valuations utilizing Level 3 valuation inputs. The $23.5 million reported fair value 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 based on collateral valuations utilizing Level 3 valuation inputs. Fair values were based on third party appraisals.

OREO

Certain foreclosed assets, upon initial recognition, are valued based on third party appraisals less estimated selling costs. At June 30, 2015 and December 31, 2014, OREO had a carrying value of $609,000 and $568,000, 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):

	June 30, 2015				December 31, 2014

Derivative liabilities	33,576		33,576		31,176		31,176

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

Cash and cash equivalents

The carrying amounts reported in the consolidated balance sheets 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 held for investment, 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.

Derivatives

The estimated fair value of interest rate swaps and caps 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 certificate of deposit fair values are estimated using a discounted cash flow calculation that applies interest rates currently being offered on similar 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 values reported in the consolidated balance sheets for Federal funds purchased, customer repurchase agreements and other short-term, floating rate borrowings approximate their fair values, which are characterized as Level 2 assets in the fair value hierarchy. The fair values 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 are characterized as Level 3 liabilities in the fair value hierarchy. The subordinated notes are publicly traded and are valued based on market prices, which are characterized as Level 2 liabilities in the fair value hierarchy.

Available-for-sale Securities [Abstract]

SECURITIES

SECURITIES

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 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.

At June 30, 2015, our net unrealized gain on the available-for-sale securities portfolio was $1.6 million compared to $2.0 million at December 31, 2014. As a percent of outstanding balances, the unrealized gain was 4.70% and 4.99% at June 30, 2015, and December 31, 2014, respectively. The decrease in the unrealized gain percentage at June 30, 2015 is related to the reduction in the portfolio balance due to paydowns and maturities.

Securities with carrying values of approximately $25.5 million were pledged to secure certain borrowings and deposits at June 30, 2015. Of the pledged securities at June 30, 2015, approximately $8.4 million were pledged for certain deposits, and approximately $17.1 million were pledged for repurchase agreements.

The following table discloses, as of June 30, 2015 and December 31, 2014, 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 June 30, 2015, we owned one security with an unrealized loss position. This security is a publicly traded equity fund and is subject to market pricing volatility. We do not believe 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.
