FIRST FINANCIAL BANKSHARES, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Note 1—Basis of Presentation

The interim consolidated financial statements include the accounts of the Company, a Texas corporation and a financial holding company registered under the Bank Holding Company Act of 1956, as amended, or BHCA, and its wholly-owned subsidiaries: First Financial Bank, National Association, Abilene, Texas; First Technology Services, Inc.; First Financial Trust & Asset Management Company, National Association; First Financial Investments, Inc.; and First Financial Insurance Agency, Inc.

Through our subsidiary bank, we conduct full-service commercial banking business. Our banking centers are located primarily in Central, North Central and West Texas. As of March 31, 2013, we had 56 financial centers across Texas, with eleven locations in Abilene, two locations in Cleburne, two locations in Stephenville, two locations in Granbury, three locations in San Angelo, three locations in Weatherford, and one location each in Mineral Wells, Hereford, Sweetwater, Eastland, Ranger, Rising Star, Cisco, Southlake, Grapevine, Aledo, Willow Park, Brock, Alvarado, Burleson, Keller, Trophy Club, Boyd, Bridgeport, Decatur, Roby, Trent, Merkel, Clyde, Moran, Albany, Midlothian, Crowley, Glen Rose, Odessa, Waxahachie, Acton, Fort Worth and Huntsville. Our trust subsidiary has six locations which consist of Abilene, San Angelo, Stephenville, Sweetwater, Fort Worth and Odessa, all in Texas.

In the opinion of management, the unaudited interim consolidated financial statements reflect all adjustments necessary for a fair presentation of the Company’s financial position and unaudited results of operations and should be read in conjunction with the Company’s audited consolidated financial statements, and notes thereto in the Company’s Annual Report on Form 10-K, for the year ended December 31, 2012. All adjustments were of a normal recurring nature. However, the results of operations for the three months ended March 31, 2013, are not necessarily indicative of the results to be expected for the year ending December 31, 2013, due to seasonality, changes in economic conditions and loan credit quality, interest rate fluctuations, regulatory and legislative changes and other factors. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted under SEC rules and regulations. The Company evaluated subsequent events for potential recognition and/or disclosure through the date the consolidated financial statements were issued.

Effective December 30, 2012, the Company consolidated its eleven bank charters into one charter. The Company cited regulatory, compliance and technology complexities and the opportunity for cost savings as its reason for making this change. The Company noted it expects to operate the one charter as it previously did with eleven charters with local management and board decisions to benefit the customers and communities it serves.

On October 26, 2011, the Company’s Board of Directors authorized the repurchase of up to 750,000 common shares through September 30, 2014. The stock buyback plan authorizes management to repurchase the stock at such time as repurchases are considered beneficial to shareholders. Any repurchase of stock will be made through the open market, block trades or in privately negotiated transactions in accordance with applicable laws and regulations. Under the repurchase plan, there is no minimum number of shares that the Company is required to repurchase. Through March 31, 2013, no shares have been repurchased under this authorization.

On April 24, 2012, the Company’s shareholders approved an amendment to the Company’s Amended and Restated Certificate of Formation to increase the number of authorized common shares to 80,000,000.

Goodwill and other intangible assets are evaluated annually for impairment as of the end of the second quarter. No such impairment has been noted in connection with the current or any prior evaluations.

Note 2—Earnings Per Share

Basic earnings per common share is computed by dividing net income available to common shareholders by the weighted average number of shares outstanding during the periods presented. In computing diluted earnings per common share for the three months ended March 31, 2013 and 2012, the Company assumes that all dilutive outstanding options to purchase common stock have been exercised at the beginning of the period (or the time of issuance, if later). The dilutive effect of the outstanding options is reflected by application of the treasury stock method, whereby the proceeds from the exercised options are assumed to be used to purchase common stock at the average market price during the respective periods. The weighted average common shares outstanding used in computing basic earnings per common share for the three months ended March 31, 2013 and 2012, were 31,507,975 and 31,466,706 shares, respectively. The weighted average common shares outstanding used in computing fully diluted earnings per common share for the three months ended March 31, 2013 and 2012, were 31,601,364 and 31,479,743 respectively.

Note 3 – Interest-bearing Time Deposits in Banks and Securities

Interest-bearing time deposits in banks totaled $45,172,000 and $49,005,000 at March 31, 2013 and December 31, 2012, respectively, and have original maturities generally ranging from one to two years. Of these amounts, $40,943,000 and $44,776,000 are time deposits with balances greater than $100,000 at March 31, 2013 and December 31, 2012, respectively.

The Company records its available-for-sale and trading securities portfolio at fair value.

Management classifies debt and equity securities as held-to-maturity, available-for-sale, or trading based on its intent. Debt securities that management has the positive intent and ability to hold to maturity are classified as held-to-maturity and recorded at cost, adjusted for amortization of premiums and accretion of discounts, which are recognized as adjustments to interest income using the interest method. Securities not classified as held-to-maturity or trading are classified as available-for-sale and recorded at estimated fair value, with all unrealized gains and unrealized losses judged to be temporary, net of deferred income taxes, excluded from earnings and reported in the consolidated statements of comprehensive earnings. Available-for-sale securities that have unrealized losses that are judged other than temporary are included in gain (loss) on sale of securities and a new cost basis is established. Securities classified as trading are recorded at estimated fair value with unrealized gains and losses included in earnings.

Fair values of these securities are determined based on methodologies in accordance with current authoritative accounting guidance. Fair values are volatile and may be influenced by a number of factors, including market interest rates, prepayment speeds, discount rates, credit ratings and yield curves. Fair values for investment securities are based on quoted market prices, where available. If quoted market prices are not available, fair values are based on the quoted prices of similar instruments or an estimate of fair value by using a range of fair value estimates in the market place as a result of the illiquid market specific to the type of security.

When the fair value of a security is below its amortized cost, and depending on the length of time the condition exists and the extent the fair value is below amortized cost, additional analysis is performed to determine whether an other-than-temporary impairment condition exists. Available-for-sale and held-to-maturity securities are analyzed quarterly for possible other-than-temporary impairment. The analysis considers (i) whether we have the intent to sell our securities prior to recovery and/or maturity, (ii) whether it is more likely than not that we will have to sell our securities prior to recovery and/or maturity, (iii) the length of time and extent to which the fair value has been less than costs, and (iv) the financial condition of the issuer. Often, the information available to conduct these assessments is limited and rapidly changing, making estimates of fair value subject to judgment. If actual information or conditions are different than estimated, the extent of the impairment of the security may be different than previously estimated, which could have a material effect on the Company’s results of operations and financial condition.

8

The Company’s investment portfolio consists of traditional investments, substantially all in U.S. Treasury securities, obligations of U.S. government sponsored-enterprises and agencies, mortgage pass-through securities, corporate bonds and general obligation or revenue based municipal bonds. Pricing for such securities is generally readily available and transparent in the market. The Company utilizes independent third party pricing services to assist in valuing its investment securities. The Company reviews the prices supplied by the independent pricing services as well as the underlying pricing methodologies for reasonableness and to ensure such prices are aligned with traditional pricing matrices. The Company validates quarterly, on a sample basis, prices supplied by the independent pricing services by comparison to prices obtained from other third party sources.

A summary of available-for-sale and held-to-maturity securities follows (in thousands):

The Company invests in mortgage-backed securities that have expected maturities that differ from their contractual maturities. These differences arise because borrowers may have the right to call or prepay obligations with or without a prepayment penalty. These securities include collateralized mortgage obligations (CMOs) and other asset backed securities. The expected maturities of these securities at March 31, 2013, were computed by using scheduled amortization of balances and historical prepayment rates. At March 31, 2013 and December 31, 2012, the Company did not hold any CMOs that entail higher risks than standard mortgage-backed securities.

The number of investment positions in an unrealized loss position totaled 108 at March 31, 2013. We do not believe these unrealized losses are “other than temporary” as (i) we do not have the intent to sell our securities prior to recovery and/or maturity and (ii) it is more likely than not that we will not have to sell our securities prior to recovery and/or maturity. In making the determination, we also consider the length of time and extent to which fair value has been less than cost and the financial condition of the issuer. The unrealized losses noted are interest rate related due to the level of interest rates at March 31, 2013 compared to the time of purchase. We have reviewed the ratings of the issuers and have not identified any issues related to the ultimate repayment of principal as a result of credit concerns on these securities. Our mortgage related securities are backed by GNMA, FNMA and FHLMC or are collateralized by securities backed by these agencies.

Securities, carried at approximately $870,328,000 at March 31, 2013, were pledged as collateral for public or trust fund deposits, repurchase agreements and for other purposes required or permitted by law.

During the quarter ended March 31, 2013 and 2012, sales of investment securities that were classified as available-for-sale totaled $5,227,000 and $21,003,000, respectively. Gross realized gains from securities sales and calls during the first quarter of 2013 and 2012 totaled $223,000 and $346,000, respectively. Gross realized losses from securities sales and calls during the first quarter of 2013 totaled $1,000. There were no losses realized on securities sales and calls during the first quarter of 2012. The specific identification method was used to determine cost in order to compute the realized gains and losses.

Note 4 –Loans and Allowance for Loan Losses

Loans held for investment are stated at the amount of unpaid principal, reduced by unearned income and an allowance for loan losses. Interest on loans is calculated by using the simple interest method on daily balances of the principal amounts outstanding. The Company defers and amortizes net loan origination fees and costs as an adjustment to yield. The allowance for loan losses is established through a provision for loan losses charged to expense. Loans are charged against the allowance for loan losses when management believes the collectability of the principal is unlikely.

The Company has certain lending policies and procedures in place that are designed to maximize loan income with an acceptable level of risk. Management reviews and approves these policies and procedures on a regular basis and makes changes as appropriate. Management receives and reviews frequent reports related to loan originations, quality, concentrations, delinquencies, non-performing and potential problem loans. Diversification in the loan portfolio is a means of managing risk associated with fluctuations in economic conditions, both by type of loan and geographic location.

Commercial loans are underwritten after evaluating and understanding the borrower’s ability to operate profitably and effectively. Underwriting standards are designed to determine whether the borrower possesses sound business ethics and practices and to evaluate current and projected cash flows to determine the ability of the borrower to repay their obligations as agreed. Commercial loans are primarily made based on the identified cash flows of the borrower and, secondarily, on the underlying collateral provided by the borrower. Most commercial loans are secured by the assets being financed or other business assets, such as accounts receivable or inventory and include personal guarantees.

Agricultural loans are subject to underwriting standards and processes similar to commercial loans. These agricultural loans are based primarily on the identified cash flows of the borrower and secondarily on the underlying collateral provided by the borrower. Most agricultural loans are secured by the agriculture related assets being financed, such as farm land, cattle or equipment and include personal guarantees.

Real estate loans are also subject to underwriting standards and processes similar to commercial and agricultural loans. These loans are underwritten primarily based on projected cash flows and, secondarily, as loans secured by real estate. The repayment of real estate loans is generally largely dependent on the successful operation of the property securing the loans or the business conducted on the property securing the loan. Real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy. The properties securing the Company’s real estate portfolio are generally diverse in terms of type and geographic location. This diversity helps reduce the exposure to adverse economic events that affect any single market or industry. Generally, real estate loans are owner occupied which further reduces the Company’s risk.

Consumer loan underwriting utilizes methodical credit standards and analysis to supplement the Company’s underwriting policies and procedures. The Company’s loan policy addresses types of consumer loans that may be originated and the collateral, if secured, which must be perfected. The relatively smaller individual dollar amounts of consumer loans that are spread over numerous individual borrowers also minimize the Company’s risk.

12

The allowance is an amount management believes is appropriate to absorb probable losses that have been incurred on existing loans as of the balance sheet date based upon management’s review and evaluation of the loan portfolio. The allowance for loan losses is comprised of three elements: (i) specific reserves determined in accordance with current authoritative accounting guidance based on probable losses on specific classified loans; (ii) general reserve determined in accordance with current authoritative accounting guidance that considers historical loss rates; and (iii) qualitative reserves determined in accordance with current authoritative accounting guidance based upon general economic conditions and other qualitative risk factors both internal and external to the Company. The allowance for loan losses is increased by charges to income and decreased by charge-offs (net of recoveries). Management’s periodic evaluation of the appropriateness of the allowance is based on general economic conditions, the financial condition of borrowers, the value and liquidity of collateral, delinquency, prior loan loss experience, and the results of periodic reviews of the portfolio. For purposes of determining our general reserve, the loan portfolio, less cash secured loans, government guaranteed loans and classified loans, is multiplied by the Company’s historical loss rate. Our methodology is constructed so that specific allocations are increased in accordance with deterioration in credit quality and a corresponding increase in risk of loss on a particular loan. In addition, we adjust our allowance for qualitative factors such as current local economic conditions and trends, including, without limitations, unemployment, changes in lending staff, policies and procedures, changes in credit concentrations, changes in the trends and severity of problem loans and changes in trends in volume and terms of loans. This additional allocation based on qualitative factors serves to compensate for additional areas of uncertainty inherent in our portfolio that are not reflected in our historic loss factors.

Although we believe we use the best information available to make loan loss allowance determinations, future adjustments could be necessary if circumstances or economic conditions differ substantially from the assumptions used in making our initial determinations. A further downturn in the economy and employment could result in increased levels of non-performing assets and charge-offs, increased loan provisions and reductions in income. Additionally, bank regulatory agencies periodically review our allowance for loan losses and could require additions to the loan loss allowance based on their judgment of information available to them at the time of their examination.

Accrual of interest is discontinued on a loan and payments are applied to principal when management believes, after considering economic and business conditions and collection efforts, the borrower’s financial condition is such that collection of interest is doubtful. Except consumer loans, generally all loans past due greater than 90 days, based on contractual terms, are placed on non-accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Consumer loans are generally charged-off when a loan becomes past due 90 days. For other loans in the portfolio, facts and circumstances are evaluated in making charge-off decisions.

Loans are considered impaired when, based on current information and events, management determines that it is probable we will be unable to collect all amounts due in accordance with the original contractual terms of the loan agreement, including scheduled principal and interest payments. If a loan is impaired, a specific valuation allowance is allocated, if necessary. Interest payments on impaired loans are typically applied to principal unless collectability of the principal amount is reasonably assured, in which case interest is recognized on a cash basis. Impaired loans, or portions thereof, are charged off when deemed uncollectable.

The Company’s policy requires measurement of the allowance for an impaired, collateral dependent loan based on the fair value of the collateral. Other loan impairments are measured based on the present value of expected future cash flows or the loan’s observable market price. At March 31, 2013 and 2012, and December 31, 2012, all significant impaired loans have been determined to be collateral dependent and the allowance for loss has been measured utilizing the estimated fair value of the collateral.

13

From time to time, the Company modifies its loan agreement with a borrower. A modified loan is considered a troubled debt restructuring when two conditions are met: (i) the borrower is experiencing financial difficulty and (ii) concessions are made by the Company that would not otherwise be considered for a borrower with similar credit risk characteristics. Modifications to loan terms may include a lower interest rate, a reduction of principal, or a longer term to maturity. To date, these troubled debt restructurings have been such that, after considering economic and business conditions and collection efforts, the collection of interest is doubtful and therefore the loan has been placed on non-accrual. Each of these loans is evaluated for impairment and a specific reserve is recorded based on probable losses, taking into consideration the related collateral and modified loan terms and cash flow. As of March 31, 2013 and 2012, and December 31, 2012, all of the Company’s troubled debt restructured loans are included in the non-accrual totals.

The Company originates certain mortgage loans for sale in the secondary market. Accordingly, these loans are classified as held for sale and are carried at the lower of cost or fair value on an aggregate basis. Loans held for sale totaled $10,122,000, $5,695,000 and $11,457,000, at March 31, 2013 and 2012 and December 31, 2012, respectively, in which the carrying amounts approximate fair value. The mortgage loan sales contracts contain indemnification clauses should the loans default, generally in the first three to six months, or if documentation is determined not to be in compliance with regulations. The Company’s historic losses as a result of these indemnities have been insignificant.

The Company recognized interest income on impaired loans prior to being recognized as impaired of approximately $384,000 during the year ended December 31, 2012. Such amounts for the three-month period ended March 31, 2013 and 2012 were not significant.

From a credit risk standpoint, the Company classifies its loans in one of four categories: (i) pass, (ii) special mention, (iii) substandard, or (iv) doubtful. Loans classified as loss are charged-off.

The classifications of loans reflect a judgment about the risks of default and loss associated with the loan. The Company reviews the ratings on our credits as part of our on-going monitoring of the credit quality of our loan portfolio. Ratings are adjusted to reflect the degree of risk and loss that are felt to be inherent in each credit as of each monthly reporting period. Our methodology is structured so that specific allocations are increased in accordance with deterioration in credit quality (and a corresponding increase in risk and loss) or decreased in accordance with improvement in credit quality (and a corresponding decrease in risk and loss).

Credits rated special mention show clear signs of financial weaknesses or deterioration in credit worthiness, however, such concerns are not so pronounced that the Company generally expects to experience significant loss within the short-term. Such credits typically maintain the ability to perform within standard credit terms and credit exposure is not as prominent as credits rated more harshly.

Credits rated substandard are those in which the normal repayment of principal and interest may be, or has been, jeopardized by reason of adverse trends or developments of a financial, managerial, economic or political nature, or important weaknesses exist in collateral. A protracted workout on these credits is a distinct possibility. Prompt corrective action is therefore required to strengthen the Company’s position, and/or to reduce exposure and to assure that adequate remedial measures are taken by the borrower. Credit exposure becomes more likely in such credits and a serious evaluation of the secondary support to the credit is performed.

Credits rated doubtful are those in which full collection of principal appears highly questionable, and which some degree of loss is anticipated, even though the ultimate amount of loss may not yet be certain and/or other factors exist which could affect collection of debt. Based upon available information, positive action by the Company is required to avert or minimize loss. Credits rated doubtful are generally also placed on non-accrual.

During the three months ended March 31, 2013, 11 loans totaling $1,167,000 that had been modified as a troubled debt restructured loan within the previous 12 months defaulted on the modified loan. A default for purposes of this disclosure is a troubled debt restructured loan in which the borrower is 90 days past due or results in the foreclosure and repossession of the applicable collateral. There were no such defaults for the three months ended March 31, 2012. The loans are as follows (dollars in thousands):

As of March 31, 2013, the Company has no commitments to lend additional funds to loan customers whose terms have been modified in troubled debt restructurings.

Our subsidiary bank has established a line of credit with the Federal Home Loan Bank of Dallas to provide liquidity and meet pledging requirements for those customers eligible to have securities pledged to secure certain uninsured deposits. At March 31, 2013, approximately $1,118,519,000 in loans held by the bank were subject to blanket liens as security for these lines of credit. At March 31, 2013, $68,600,000 in letters of credit issued by the Federal Home Loan Bank of Dallas were outstanding under these lines of credit. The letters of credit were pledged as collateral for public funds held by our bank.

Note 5 – Income Taxes

Income tax expense was $6,182,000 for the first quarter in 2013 as compared to $6,035,000 for the same period in 2012. Our effective tax rates on pretax income were 25.0% and 25.4% for the first quarter of 2013 and 2012, respectively. The effective tax rates differ from the statutory federal tax rate of 35% largely due to tax exempt interest income earned on certain investment securities and loans, the deductibility of dividends paid to our employee stock ownership plan and Texas state taxes.

Note 6 – Stock Based Compensation

The Company grants incentive stock options for a fixed number of shares with an exercise price equal to the fair value of the shares at the date of grant to employees. No options have been granted in 2013 or 2012. The Company recorded stock option expense totaling approximately $88,000 thousand and $88,000, respectively, for the three-month periods ended March 31, 2013 and 2012. The additional disclosure requirements under authoritative accounting guidance have been omitted due to immateriality.

Note 7 – Pension Plan

The Company’s defined benefit pension plan was frozen effective January 1, 2004, whereby no additional years of service will accrue to participants, unless the pension plan is reinstated at a future date. The pension plan covered substantially all of the Company’s employees at the time. The benefits for each employee were based on years of service and a percentage of the employee’s qualifying compensation during the final years of employment. The Company’s funding policy was and is to contribute annually the amount necessary to satisfy the Internal Revenue Service’s funding standards. Contributions to the pension plan, prior to freezing the plan, were intended to provide not only for benefits attributed to service to date but also for those expected to be earned in the future. As a result of the Pension Protection Act of 2006 (the “Protection Act”), the Company will be required to contribute amounts in future years to fund any shortfalls. The Company has evaluated the provisions of the Protection Act as well as the Internal Revenue Service’s funding standards to develop a plan for funding in future years. The Company made a contribution totaling $2,000,000 in 2012 and has to date made no contributions in 2013.

Net periodic benefit costs totaling $208,000 and $185,000 were recorded, respectively, for the three months ended March 31, 2013 and 2012.

Note 8 – Recently Issued Authoritative Accounting Guidance

In 2011 and 2013, the Financial Accounting Standards Board (the “FASB”) amended its authoritative guidance related to offsetting assets and liabilities to require an entity to disclose both gross and net information about financial instruments, such as sales and repurchase agreements and reverse sales and repurchase agreements and securities borrowing/lending arrangements, and derivative instruments that are eligible for offset in the statement of financial position and/or subject to a master netting arrangement or similar agreement. The new guidance was effective for annual and interim periods beginning on January 1, 2013, and did not have a significant impact on the Company’s financial statements.

In 2013, the FASB amended its authoritative guidance related to reporting of reclassifications out of other comprehensive earnings. The new guidance sets requirements for presentation for significant items reclassified to net earnings during the period presented. The new guidance was effective for annual and interim periods beginning on January 1, 2013 and have been included in these financial statements.

Note 9 – Fair Value Disclosures

The authoritative accounting guidance for fair value measurements defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. The price in the principal (or most advantageous) market used to measure the fair value of the asset or liability shall not be adjusted for transaction costs. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets and liabilities; it is not a forced transaction. Market participants are buyers and sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact, and (iv) willing to transact.

The authoritative accounting guidance requires the use of valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities. The income approach uses valuation techniques to convert future amounts, such as cash flows or earnings, to a single present amount on a discounted basis. The cost approach is based on the amount that currently would be required to replace the service capacity of an asset (replacement costs). Valuation techniques should be consistently applied. Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the asset or liability. Inputs may be observable, meaning those

20

that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources, or unobservable, meaning those that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. In that regard, the authoritative guidance establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

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

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

• Level 3 Inputs – Significant unobservable inputs that reflect an entity’s own assumptions that market participants would use in pricing the assets or liabilities.

A description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below.

In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon internally developed models that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. While management believes the Company’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date.

Securities classified as available-for-sale and trading are reported at fair value utilizing Level 1 and Level 2 inputs. For these securities, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include market spreads, cash flows, the United States Treasury yield curve, live trading levels, trade execution data, dealer quotes, market consensus prepayments speeds, credit information and the security’s terms and conditions, among other items. Securities are considered to be measured with Level 1 inputs at the time of purchase and for 30 days following. After 30 days, the majority of securities are transferred to Level 2 as they are considered to be measured with Level 2 inputs, with the exception of U. S. Treasury securities and any other security for which there remain Level 1 inputs. Transfers are recognized on the actual date of transfer.

There were no transfers between Level 2 and Level 3 during the three months ended March 31, 2013 or 2012.

The following table summarizes financial assets and financial liabilities measured at fair value on a recurring basis as of March 31, 2013, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value (dollars in thousands):

	Level 1 Inputs		Level 2 Inputs		Level 3 Inputs		Total Fair Value

U. S. Treasury securities	$	6,039	$	—	$	—	$	6,039

Certain financial assets and financial liabilities are measured at fair value on a nonrecurring basis, that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). Financial assets and financial liabilities measured at fair value on a non-recurring basis include the following at March 31, 2013:

Impaired Loans – Impaired loans are reported at the fair value of the underlying collateral if repayment is expected solely from the collateral. Collateral values are estimated using Level 2 inputs based on observable market data, or Level 3 input based on the discounting of the collateral. At March 31, 2013, impaired loans with a carrying value of $22,509,000 were reduced by specific valuation reserves totaling $5,793,000 resulting in a net fair value of $16,716,000.

Loans Held for Sale – Loans held for sale are reported at the lower of cost or fair value. In determining whether the fair value of loans held for sale is less than cost when quoted market prices are not available, the Company considers investor commitments/contracts. These loans are considered Level 2 of the fair value hierarchy. At March 31, 2013, the Company’s mortgage loans held for sale were recorded at cost as fair value exceeded cost.

Certain non-financial assets and non-financial liabilities measured at fair value on a non-recurring basis include other real estate owned, goodwill and other intangible assets and other non-financial long-lived assets. Non-financial assets measured at fair value on a non-recurring basis during the three months ended March 31, 2013 and 2012 include other real estate owned which, subsequent to their initial transfer to other real estate owned from loans, were re-measured at fair value through a write-down included in gain (loss) on sale of foreclosed assets. During the reported periods, all fair value measurements for foreclosed assets utilized Level 2 inputs based on observable market data, generally third-party appraisals, or Level 3 inputs based on customized discounting criteria. These appraisals are evaluated individually and discounted are as necessary due to the age of the appraisal, lack of comparable sales, expected holding periods of property or special use type of the property. Such discounts vary by appraisal based on

22

the above factors but generally range from 5% to 25% of the appraised value. Reevaluation of other real estate owned is performed at least annually as required by regulatory guidelines or more often if particular circumstances arise. The following table presents other real estate owned that were re-measured subsequent to their initial transfer to other real estate owned (dollars in thousands):

	Three months ended March 31,
	2013			2012
Carrying value of other real estate owned prior to re-measurement	$	1,827		$	417
Write-downs included in gain (loss) on sale of other real estate owned		(304	)		(101	)
Fair value	$	1,523		$	316

At March 31, 2013 and 2012, and December 31, 2012, other real estate owned totaled $3,052,000, $7,815,000 and $3,505,000, respectively.

The Company is required under current authoritative accounting guidance to disclose the estimated fair value of their financial instrument assets and liabilities including those subject to the requirements discussed above. For the Company, as for most financial institutions, substantially all of its assets and liabilities are considered financial instruments, as defined. Many of the Company’s financial instruments, however, lack an available trading market as characterized by a willing buyer and willing seller engaging in an exchange transaction.

The estimated fair value amounts of financial instruments have been determined by the Company using available market information and appropriate valuation methodologies. However, considerable judgment is required to interpret data to develop the estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could realize in a current market exchange. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.

In addition, reasonable comparability between financial institutions may not be likely due to the wide range of permitted valuation techniques and numerous estimates that must be made given the absence of active secondary markets for many of the financial instruments. This lack of uniform valuation methodologies also introduces a greater degree of subjectivity to these estimated fair values.

Cash and due from banks, federal funds sold, interest-bearing deposits and time deposits in banks and accrued interest receivable and payable are liquid in nature and considered Level 1 or 2 of the fair value hierarchy.

Financial instruments with stated maturities have been valued using a present value discounted cash flow with a discount rate approximating current market for similar assets and liabilities and are considered Levels 2 and 3 of the fair value hierarchy. Financial instrument liabilities with no stated maturities have an estimated fair value equal to both the amount payable on demand and the carrying value and are considered Level 1 of the fair value hierarchy.

The carrying value and the estimated fair value of the Company’s contractual off-balance-sheet unfunded lines of credit, loan commitments and letters of credit, which are generally priced at market at the time of funding, are not material.

23

The estimated fair values and carrying values of all financial instruments under current authoritative guidance at March 31, 2013 and December 31, 2012, were as follows (in thousands):

Introduction

As a financial holding company, we generate most of our revenue from interest on loans and investments, trust fees, and service charges. Our primary source of funding for our loans and investments are deposits held by our subsidiary bank. Our largest expenses are interest on these deposits and salaries and related employee benefits. We usually measure our performance by calculating our return on average assets, return on average equity, our regulatory leverage and risk based capital ratios, and our efficiency ratio, which is calculated by dividing noninterest expense by the sum of net interest income on a tax equivalent basis and noninterest income.

The following discussion of operations and financial condition should be read in conjunction with the financial statements and accompanying footnotes included in Item 1 of this Form 10-Q as well as those included in the Company’s 2012 Annual Report on Form 10-K.

Critical Accounting Policies

We prepare consolidated financial statements based on generally accepted accounting principles and customary practices in the banking industry. These policies, in certain areas, require us to make significant estimates and assumptions.

We deem a policy critical if (1) the accounting estimate required us to make assumptions about matters that are highly uncertain at the time we make the accounting estimate; and (2) different estimates that reasonably could have been used in the current period, or changes in the accounting estimate that are reasonably likely to occur from period to period, would have a material impact on the financial statements.

We deem our most critical accounting policies to be (1) our allowance for loan losses and our provision for loan losses and (2) our valuation of securities. We have other significant accounting policies and continue to evaluate the materiality of their impact on our consolidated financial statements, but we believe these other policies either do not generally require us to make estimates and judgments that are difficult or subjective, or it is less likely they would have a material impact on our reported results for a given period. A discussion of (1) our allowance for loan losses and our provision for loan losses and (2) our valuation of securities is included in note 4 and note 3, respectively, to our notes to consolidated financial statements (unaudited) which begins on page 7.

Consolidation of Bank Charters

Effective December 30, 2012, the Company consolidated its eleven bank charters into one charter. The Company cited regulatory, compliance and technology complexities and the opportunity for cost savings as its reason for making this change. The Company noted it expects to operate its subsidiary bank as it previously did with eleven charters with local management and board decisions to benefit the customers and communities it serves.

Results of Operations

Performance Summary. Net earnings for the first quarter of 2013 were $18.58 million compared to $17.76 million for the same period in 2012, or a 4.62% increase over the same period in 2012.

Basic earnings per share for the first quarter of 2013 were $0.59 compared to $0.56 for the same quarter last year. The return on average assets was 1.71% for the first quarter of 2013, as compared to 1.73% for the same quarter of 2012. The return on average equity was 13.41% for the first quarter of 2013 as compared to 13.79% for the same quarter of 2012.

Net Interest Income. Net interest income is the difference between interest income on earning assets and interest expense on liabilities incurred to fund those assets. Our earning assets consist primarily of loans and investment securities. Our liabilities to fund those assets consist primarily of noninterest-bearing and interest-bearing deposits.

Tax-equivalent net interest income was $42.47 million for the first quarter of 2013, as compared to $41.75 million for the same period last year. The increase in 2013 compared to 2012 was largely attributable to the decrease in rate of interest bearing liabilities. Average earning assets increased $283.68 million for the first quarter of 2013 over the same period in 2012. Average tax exempt securities and average loans increased $133.87 million and $326.95 million, respectively, for the first quarter of 2013 over the first quarter of 2012. Average interest bearing liabilities increased $97.27 million for the first quarter of 2013, as compared to the same period in 2012. The yield on earning assets decreased 27 basis points during the first quarter of 2013, whereas the rate paid on interest-bearing liabilities decreased 11 basis points in the first quarter of 2013 primarily due to the effects of lower interest rates.

Table 1 allocates the change in tax-equivalent net interest income between the amount of change attributable to volume and to rate.

The net interest margin for the first quarter of 2013 was 4.19%, a decrease of 20 basis points from the same period in 2012. The target Federal funds rate was reduced to a range of zero to 25 basis points in December 2008. The low level of interest rates has reduced the yields on our short-term investments and investment securities as the proceeds from maturing investment securities have been invested at much lower rates. We have been able to partially mitigate the impact of low short-term interest rates by establishing minimum interest rates on certain of our loans, improving the pricing for loan risk, and reducing rates paid on interest bearing liabilities. We expect interest rates to remain at the current low levels until 2015 as announced by the Federal Reserve, which will continue to place pressure on our interest margin.

The net interest margin, which measures tax-equivalent net interest income as a percentage of average earning assets, is illustrated in Table 2.

Noninterest Income. Noninterest income for the first quarter of 2013 was $13.96 million, an increase of $662 thousand over the same period in 2012. Trust fees increased $339 thousand and real estate mortgage operations increased $334 thousand. The increase in trust fees reflects an increase in estate fees, fees from mineral management and an increase in assets under management over the prior year from both improved market conditions and growth in assets managed. The fair value of our trust assets managed,

28

which are not reflected in our consolidated balance sheet, totaled $3.02 billion at March 31, 2013 as compared to $2.63 billion for the same date in 2012. Real estate mortgage income increased primarily due to a stronger housing market and increased market share.

Offsetting these increases was a decrease in our net gain on sale of available for sale securities of $124 thousand and a loss on sale of foreclosed assets of $322 thousand.

Noninterest Expense. Total noninterest expense for the first quarter of 2013 was $27.47 million, an increase of $1.00 million, or 3.79%, as compared to the same period in 2012. An important measure in determining whether a banking company effectively manages noninterest expenses is the efficiency ratio, which is calculated by dividing noninterest expense by the sum of net interest income on a tax-equivalent basis and noninterest income. Lower ratios indicate better efficiency since more income is generated with a lower noninterest expense total. Our efficiency ratio for the first quarter of 2013 was 48.68%, compared to 48.08% from the same period in 2012.

Salaries and employee benefits for the first quarter of 2013 totaled $15.18 million, an increase of $951 thousand compared to 2012. The increase was largely the result of additional employees to staff new branches and annual pay increases.

All other categories of noninterest expense for the first quarter of 2013 totaled $12.29 million, an increase of $52 thousand, or 0.42%, as compared to the same period in 2012. Categories of noninterest expense with increases included ATM, interchange and credit card expense, equipment expense and professional and service fees. Offsetting these increases were decreases in operation and other losses, legal fees and regulatory exam fees. Included in noninterest expense for the first quarter of 2013 are costs, primarily legal and travel, totaling $143 thousand related to the Company’s recently announced acquisition of Orange Savings Bank, SSB, which is expected to close in the second quarter of 2013.

Balance Sheet Review

Loans. Our portfolio is comprised of loans made to businesses, professionals, individuals, and farm and ranch operations located in the primary trade areas served by our subsidiary bank. Real estate loans represent loans primarily for 1-4 family residences and owner-occupied commercial real estate. The structure of loans in the real estate mortgage area generally provides re-pricing intervals to minimize the interest rate risk inherent in long-term fixed rate loans. As of March 31, 2013, total loans held for investment were $2.13 billion, an increase of $50.85 million, as compared to December 31, 2012. As compared to December 31, 2012, commercial loans increased $3.8 million, agricultural loans decreased $13.1 million, real estate loans increased $48.7 million, and consumer loans increased $11.4 million. Loans averaged $2.11 billion during the first quarter of 2013, an increase of $326.9 million from the prior year first quarter average balances.

Commercial	$	513,422	$	433,351	$	509,609

Total loans held for investment	$	2,128,015	$	1,793,172	$	2,077,166

At March 31, 2013, our real estate loans represent approximately 60.2% of our loan portfolio and are comprised of (i) 1-4 family residence loans of 43.6%, (ii) commercial real estate loans of 28.2%, generally owner occupied, (iii) other loans, which includes ranches, hospitals and universities, of 18.6%, (iv) residential development and construction loans of 5.7%, which includes our custom and speculation home construction loans and (v) commercial development and construction loans of 3.9%.

Loans held for sale, consisting of mortgage loans, totaled $10.1 million, $5.7 million and $11.5 million at March 31, 2013 and 2012, and December 31, 2012, respectively, in which the carrying amounts approximate market.

Asset Quality. Our loan portfolios are subject to periodic reviews by our centralized independent loan review group as well as periodic examinations by state and federal bank regulatory agencies. Loans are placed on nonaccrual status when, in the judgment of management, the collectability of principal or interest under the original terms becomes doubtful. Nonaccrual, past due 90 days still accruing and restructured loans plus foreclosed assets, were $25.7 million at March 31, 2013, as compared to $28.9 million at March 31, 2012 and $25.5 million at December 31, 2012. As a percent of loans and foreclosed assets, these assets were 1.20% at March 31, 2013, as compared to 1.60% at March 31, 2012 and 1.22% at December 31, 2012. As a percent of total assets, these assets were 0.58% at March 31, 2013 as compared to 0.68% at March 31, 2012 and 0.57% at December 31, 2012. The continued higher levels of these nonperforming assets are the result of ongoing weakness in real estate markets and the national economy. We believe the level of these assets to be manageable at March 31, 2013.

As a % of total assets		0.58	%		0.68	%		0.57	%

We record interest payments received on non-accrual loans as reductions of principal. Prior to the loans being placed on non-accrual, we recognized interest income on impaired loans as of December 31, 2012 described above of approximately $287 thousand during the year ended December 31, 2012. If interest on these impaired loans had been recognized on a full accrual basis during the year ended December 31, 2012, such income would have approximated $1.67 million. Such amounts for the 2013 and 2012 interim periods were insignificant.

Provision and Allowance for Loan Losses. The allowance for loan losses is the amount we determine as of a specific date to be appropriate to absorb probable losses on existing loans in which full collectability is unlikely based on our review and evaluation of the loan portfolio. For a discussion of our methodology, see note 4 to our notes to consolidated financial statements (unaudited). The provision for loan losses was $401 thousand for the first quarter of 2013, as compared to $1.3 million for the first quarter of 2012. The continued provision for loan losses in 2013 and 2012 reflects the growth in loans and continuing higher levels of nonperforming assets. However, the general stability of our balances in non-accrual loans and reductions in net charge-offs enabled the Company to reduce its provisions in the first quarter of 2013 compared to the prior year. As a percent of average loans, net loan charge-offs were 0.11% for the first quarter of 2013 compared to 0.24% during the first quarter of 2012. The allowance for loan losses as a percent of loans was 1.62% as of March 31, 2013, as compared to 1.67% as of December 31, 2012 and 1.92% as of March 31, 2012. Included in Table 7 is further analysis of our allowance for loan losses compared to charge-offs.

Table 7 — Loan Loss Experience and Allowance for Loan Losses (in thousands, except percentages):

	Three Months Ended March 31,
	2013			2012
Allowance for loan losses at period end	$	34,672		$	34,529
Loans held for investment at period end		2,128,015			1,793,172
Average loans for period		2,111,138			1,784,192
Net charge-offs/average loans (annualized)		0.11	%		0.24	%
Allowance for loan losses/period-end loans		1.62	%		1.92	%
Allowance for loan losses/nonaccrual loans, past due 90 days still accruing and restructured loans		153.9	%		164.3	%

32

The ratio of our allowance to non-accrual, past due 90 days still accruing and restructured loans has generally trended downward since 2007, as the economic conditions worsened. Although the ratio has declined from prior years when net charge-offs and non-performing asset levels were historically low, management believes the allowance for loan losses is appropriate at March 31, 2013 in spite of these trends.

Interest-Bearing Deposits and Time Deposits in Banks. As of March 31, 2013, our interest-bearing deposits and time deposits were $65.2 million compared with $146.2 million and $188.7 million as of March 31, 2012 and December 31, 2012, respectively. At March 31, 2013, interest-bearing deposits and time deposits in banks included $45.2 million invested in FDIC-insured certificates of deposit, and $19.3 million maintained at the Federal Reserve Bank of Dallas. Interest-bearing deposits in banks results from several factors including cash flows from maturing investment securities, growth in deposits and fluctuating deposits from larger depository customers.

Available-for-Sale and Held-to-Maturity Securities. At March 31, 2013, securities with an amortized cost of $903 thousand were classified as securities held-to-maturity and securities with a fair value of $1.96 billion were classified as securities available-for-sale. As compared to December 31, 2012, the available for sale portfolio, carried at fair value, at March 31, 2013, reflected (i) a decrease of $30.2 million in U.S. Treasury securities and obligations of U.S. government sponsored-enterprises and agencies, (ii) an increase of $74.2 million in obligations of states and political subdivisions, (iii) a decrease of $6.0 million in corporate and other bonds, and (iv) an increase of $101.0 million in mortgage-backed securities. Our mortgage related securities are backed by GNMA, FNMA or FHLMC or are collateralized by securities guaranteed by these agencies.

See note 3 to consolidated financial statements (unaudited) for additional disclosures related to the maturities and fair values of the investment portfolio at March 31, 2013 and December 31, 2012.

All yields are computed on a tax-equivalent basis assuming a marginal tax rate of 35%. Yields on securities are based on amortized cost. Maturities of mortgage-backed securities are based on contractual maturities and could differ due to prepayments of underlying mortgages. Maturities of other securities are reported at the sooner of maturity date or call date.

As of March 31, 2013, the investment portfolio had an overall tax equivalent yield of 3.73%, a weighted average life of 4.61 years and modified duration of 4.07 years.

Deposits. Deposits held by subsidiary banks represent our primary source of funding. Total deposits were $3.55 billion as of March 31, 2013, as compared to $3.40 billion as of March 31, 2012. Table 9 provides a breakdown of average deposits and rates paid for the three month period ended March 31, 2013 and 2012.

Short-Term Borrowings. Included in short-term borrowings were federal funds purchased and securities sold under repurchase agreements of $263.3 million and $237.6 million at March 31, 2013 and 2012, respectively. Securities sold under repurchase agreements are generally with significant customers that require short-term liquidity for their funds which we pledge our securities that have a fair value equal to at least the amount of the short-term borrowing. The average balance of federal funds purchased and securities sold under repurchase agreements was $269.6 million and $241.7 million in the first quarters of 2013 and 2012, respectively. The average rates paid on federal funds purchased and securities sold under repurchase agreements was 0.06% and 0.10% for the first quarters of 2013 and 2012, respectively.

Capital Resources

We evaluate capital resources by our ability to maintain adequate regulatory capital ratios to do business in the banking industry. Issues related to capital resources arise primarily when we are growing at an accelerated rate but not retaining a significant amount of our profits or when we experience significant asset quality deterioration.

Total shareholders’ equity was $564.3 million, or 12.66% of total assets, at March 31, 2013, as compared to $517.0 million, or 12.23% of total assets, at March 31, 2012. Included in shareholders’ equity at March 31, 2013 and March 31, 2012, were $55.5 million and $52.3 million, respectively, in unrealized gains on investment securities available-for-sale, net of related income taxes. For the first quarter of 2013, total shareholders’ equity averaged $561.6 million, or 12.73% of average assets, as compared to $517.7 million, or 12.56% of average assets, during the same period in 2012.

Banking regulators measure capital adequacy by means of the risk-based capital ratio and leverage ratio. The risk-based capital rules provide for the weighting of assets and off-balance-sheet commitments and contingencies according to prescribed risk categories ranging from 0% to 100%. Regulatory capital is then divided by risk-weighted assets to determine the risk-adjusted capital ratios. The leverage ratio is computed by dividing shareholders’ equity less intangible assets by quarter-to-date average assets less intangible assets. Regulatory minimums to be designated “well capitalized” for total risk-based, Tier 1 risk based and leverage ratios are 10.00%, 6.00% and 5.00%, respectively. As of March 31, 2013, our total risk-based, Tier 1 risk based and leverage capital ratios were 18.80%, 17.54% and 10.69%, respectively, as compared to total risk-based, Tier 1 risk based and leverage capital ratios of 18.99%, 17.73% and 10.31% as of March 31, 2012. We believe by all measurements our capital ratios remain well above regulatory requirements to be considered “well capitalized” by the regulators.

Interest Rate Risk. Interest rate risk results when the maturity or re-pricing intervals of interest-earning assets and interest-bearing liabilities are different. Our exposure to interest rate risk is managed primarily through our strategy of selecting the types and terms of interest-earning assets and interest-bearing liabilities that generate favorable earnings while limiting the potential negative effects of changes in market interest rates. We use no off-balance-sheet financial instruments to manage or hedge interest rate risk.

Our subsidiary bank has an asset liability management committee that monitors interest rate risk and compliance with investment policies. The subsidiary bank utilizes an earnings simulation model as the primary quantitative tool in measuring the amount of interest rate risk associated with changing market rates. The model quantifies the effects of various interest rate scenarios on projected net interest income and net income over the next twelve months. The model measures the impact on net interest income relative to a base case scenario of hypothetical fluctuations in interest rates over the next twelve months. These simulations incorporate assumptions regarding balance sheet growth and mix, pricing and the re-pricing and maturity characteristics of the existing and projected balance sheet.

As of March 31, 2013, the model simulations projected that 100 and 200 basis point increases in interest rates would result in positive variances in net interest income of 0.92% and 1.84%, respectively, relative to the base case over the next twelve months, while decreases in interest rates of 50 basis points would result in a negative variance in net interest income of 2.76% relative to the base case over the next twelve months. The likelihood of a decrease in interest rates beyond 50 basis points as of March 31, 2013 is considered remote given current interest rate levels. These are good faith estimates and assume that the composition of our interest sensitive assets and liabilities existing at each year-end will remain constant over the relevant twelve month measurement period and that changes in market interest rates are instantaneous and sustained across the yield curve regardless of duration of pricing characteristics of specific assets or liabilities. Also, this analysis does not contemplate any actions that we might undertake in response to changes in market interest rates. We believe these estimates are not necessarily indicative of what actually could occur in the event of immediate interest rate increases or decreases of this magnitude. As interest-bearing assets and liabilities re-price in different time frames and proportions to market interest rate movements, various assumptions must be made based on historical relationships of these variables in reaching any conclusion. Since these correlations are based on competitive and market conditions, we anticipate that our future results will likely be different from the foregoing estimates, and such differences could be material.

Should we be unable to maintain a reasonable balance of maturities and re-pricing of our interest-earning assets and our interest-bearing liabilities, we could be required to dispose of our assets in an unfavorable manner or pay a higher than market rate to fund our activities. Our asset liability committee oversees and monitors this risk.

Liquidity

Liquidity is our ability to meet cash demands as they arise. Such needs can develop from loan demand, deposit withdrawals or acquisition opportunities. Potential obligations resulting from the issuance of standby letters of credit and commitments to fund future borrowings to our loan customers are other factors affecting our liquidity needs. Many of these obligations and commitments are expected to expire without being drawn upon; therefore the total commitment amounts do not necessarily represent future cash requirements affecting our liquidity position. The potential need for liquidity arising from these types of financial instruments is represented by the contractual notional amount of the instrument. Asset liquidity is provided by cash and assets which are readily marketable or which will mature in the near future. Liquid assets include cash, federal funds sold, and short-term investments in time deposits in banks. Liquidity is also provided by access to funding sources, which include core depositors and correspondent banks that maintain accounts with and sell federal funds to our subsidiary banks. Other sources of funds include our ability to borrow from short-term sources, such as purchasing federal funds from correspondent banks and sales of securities under agreements to repurchase, which amounted to $263.3 million at March 31, 2013, and an unfunded $25.0 million line of credit established with The Frost Bank which matures on June 30, 2013 (see next paragraph). Our bank also has federal funds purchased lines of credit with two non-affiliated banks totaling $80.0 million. No balance was outstanding on these federal funds purchased lines of credit at March 31, 2013. Our subsidiary bank has available lines of credit with the Federal Home Loan Bank of Dallas totaling $424.7 million secured by portions of their loan portfolios and certain investment securities. At March 31, 2013, $68.6 million in letters of credit issued by the Federal Home Loan Bank of Dallas were outstanding under these lines of credit, and there were no amounts outstanding in short-term borrowings under these lines. The letters of credit were pledged as collateral for public funds held by our bank.

The Company renewed its loan agreement, effective June 30, 2011, with Frost Bank. Under the loan agreement, as renewed and amended, we are permitted to draw up to $25.0 million on a revolving line of credit. Prior to June 30, 2013, interest is paid quarterly at Wall Street Journal Prime, and the line of credit matures June 30, 2013. If a balance exists at June 30, 2013, the principal balance converts to a term facility payable quarterly over five years and interest is paid quarterly at our election at Wall Street Journal Prime plus 50 basis points or LIBOR plus 250 basis points. The line of credit is unsecured. Among other provisions in the credit agreement, we must satisfy certain financial covenants during the term of the loan agreement, including, without limitation, covenants that require us to maintain certain capital, tangible net worth, loan loss reserve, non-performing asset and cash flow coverage ratio. In addition, the credit agreement contains certain operational covenants, which among others, restricts the payment of dividends above 55% of consolidated net income, limits the incurrence of debt (excluding any amounts acquired in an acquisition) and prohibits the disposal of assets except in the ordinary course of business. Since 1995, we have historically declared dividends as a percentage of our consolidated net income in a range of 37% (low) in 1995 to 53% (high) in 2003 and 2006. Management believes the Company was in compliance with the financial and operational covenants at March 31, 2013. There was no outstanding balance under the line of credit as of March 31, 2013, or December 31, 2012.

In addition, we anticipate that future acquisition of financial institutions, expansion of branch locations or offering of new products could also place a demand on our cash resources. Available cash and interest-bearing deposits in banks which totaled $69.9 million at March 31, 2013, investment securities which totaled $12.5 million which matures over 10 to 17 years, available dividends from our subsidiaries which totaled $43.6 million at March 31, 2013, utilization of available lines of credit, and future debt or equity offerings are expected to be the source of funding for these potential acquisitions or expansions. Existing cash resources at our subsidiary bank may also be used as a source of funding for these potential acquisitions or expansions.

Given the strong core deposit base, relatively low loan to deposit ratios maintained at our subsidiary bank, available lines of credit, and dividend capacity of our subsidiary bank, we consider our current liquidity position to be adequate to meet our short- and long-term liquidity needs.

Off-Balance Sheet Arrangements. We are a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of our customers. These financial instruments include unfunded lines of credit, commitments to extend credit and Federal funds sold and standby letters of credit. Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in our consolidated balance sheets.

Our exposure to credit loss in the event of nonperformance by the counterparty to the financial instrument for unfunded lines of credit, commitments to extend credit and standby letters of credit is represented by the contractual notional amount of these instruments. We generally use the same credit policies in making commitments and conditional obligations as we do for on-balance-sheet instruments.

Unfunded lines of credit and 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. These commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. We evaluate each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, as we deem necessary upon extension of credit, is based on our credit evaluation of the counterparty. Collateral held varies but may include accounts receivable, inventory, property, plant, and equipment and income-producing commercial properties.

Standby letters of credit are conditional commitments we issue to guarantee the performance of a customer to a third party. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The average collateral value held on letters of credit usually exceeds the contract amount.

Table 10 – Commitments as of March 31, 2013 (in thousands):

	Total Notional Amounts Committed
Unfunded lines of credit	$	375,202
Unfunded commitments to extend credit		106,700
Standby letters of credit		20,175
Total commercial commitments	$	502,077

We believe we have no other off-balance sheet arrangements or transactions with unconsolidated, special purpose entities that would expose us to liability that is not reflected on the face of the financial statements.

Parent Company Funding. Our ability to fund various operating expenses, dividends to shareholders, and cash acquisitions is generally dependent on our own earnings (without giving effect to our subsidiaries), cash reserves and funds derived from our subsidiaries. These funds historically have been produced by dividends from our subsidiaries and management fees that are limited to reimbursement of actual expenses. We anticipate that our recurring cash sources will continue to include dividends and management fees from our subsidiaries. At March 31, 2013, approximately $43.6 million was available for the payment of intercompany dividends by our subsidiaries without the prior approval of regulatory agencies. Our subsidiaries paid aggregate dividends of $15.4 million and $13.9 million for the three month periods ended March 31, 2013 and 2012, respectively.

37

Dividends. Our long-term dividend policy is to pay cash dividends to our shareholders of between 40% and 55% of net earnings while maintaining adequate capital to support growth. The cash dividend payout ratios have amounted to 42.4% and 42.5% of net earnings, respectively, for the first three months of 2013 and the same period in 2012. Given our current capital position and projected earnings and asset growth rates, we do not anticipate any significant change in our current dividend policy.

Our bank subsidiary is required by federal law to obtain the prior approval of the Office of the Comptroller of the Currency (the “OCC”), to declare and pay dividends if the total of all dividends declared in any calendar year would exceed the total of (1) such bank’s net profits (as defined and interpreted by regulation) for that year plus (2) its retained net profits (as defined and interpreted by regulation) for the preceding two calendar years, less any required transfers to surplus. In addition, our bank may only pay dividends to the extent that retained net profits (including the portion transferred to surplus) exceed bad debts (as defined by regulation).

To pay dividends, we and our subsidiaries must maintain adequate capital above regulatory guidelines. In addition, if the applicable regulatory authority believes that our subsidiary under its jurisdiction is engaged in or is about to engage in an unsafe or unsound practice (which, depending on the financial condition of the subsidiary, could include the payment of dividends), the authority may require, after notice and hearing, that such bank cease and desist from the unsafe practice. The Federal Reserve, the FDIC and the OCC have each indicated that paying dividends that deplete a bank’s capital base to an inadequate level would be an unsafe and unsound banking practice. The Federal Reserve, the OCC and the FDIC have issued policy statements that recommend that bank holding companies and insured banks should generally only pay dividends out of current operating earnings.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Management considers interest rate risk to be a significant market risk for the Company. See “Item 2—Management’s Discussion and Analysis of Financial Condition and Results of Operations – Capital Resources—Interest Rate Risk” for disclosure regarding this market risk.

Item 4. Controls and Procedures

As of March 31, 2013, we carried out an evaluation, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15 of the Securities Exchange Act of 1934. Our management, which includes our principal executive officer and our principal financial officer, does not expect that our disclosure controls and procedures will prevent all errors and all fraud.

A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints; additionally, the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls also is based, in part, upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may

38

become inadequate due to changes in conditions; also the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected. Our principal executive officer and principal financial officer have concluded based on our evaluation of our disclosure controls and procedures, that our disclosure controls and procedures, as defined under Rule 13a-15 of the Securities Exchange Act of 1934, are effective at the reasonable assurance level as of March 31, 2013.

There were no significant changes in our internal controls over financial reporting or other factors during the first quarter of 2013 that have materially affected, or are reasonably likely to materially affect, these internal controls.
