FIRST FINANCIAL BANKSHARES, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Note 1 – Basis of Presentation

The unaudited 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 a full-service commercial banking business. Our banking centers are located primarily in Central, North Central, Southeast and West Texas. As of March 31, 2019, we had 73 financial centers across Texas, with eleven locations in Abilene, three locations in Weatherford, two locations in Cleburne, Conroe, San Angelo, Stephenville and Granbury, and one location each in Acton, Albany, Aledo, Alvarado, Beaumont, Boyd, Bridgeport, Brock, Burleson, Cisco, Clyde, Cut and Shoot, Decatur, Eastland, El Campo, Fort Worth, Fulshear, Glen Rose, Grapevine, Hereford, Huntsville, Keller, Kingwood, Magnolia, Mauriceville, Merkel, Midlothian, Mineral Wells, Montgomery, Moran, New Waverly, Newton, Odessa, Orange, Palacios, Port Arthur, Ranger, Rising Star, Roby, Southlake, Spring, Sweetwater, Tomball, Trent, Trophy Club, Vidor, Waxahachie, Willis and Willow Park, all in Texas. Our trust subsidiary has eight locations which are located in Abilene, Fort Worth, Houston, Odessa, Beaumont, San Angelo, Stephenville and Sweetwater.

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 Form10-K, for the year ended December 31, 2018. All adjustments were of a normal recurring nature. However, the results of operations for the three months ended March 31, 2019, are not necessarily indicative of the results to be expected for the year ending December 31, 2019, due to seasonality, changes in economic conditions and loan credit quality, interest rate fluctuations, regulatory and legislative changes and other factors. The preparation of financial statements in conformity with United States generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the financial statement date. Actual results could vary. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted under U.S. Securities and Exchange Commission (“SEC”) rules and regulations. The Company evaluated subsequent events for potential recognition and/or disclosure through the date the consolidated financial statements were issued.

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 – Stock Split and Stock Repurchase

On April 23, 2019, the Company’s Board of Directors declared atwo-for-one stock split in the form of a 100% stock dividend effective for shareholders of record on May 15, 2019 to be distributed on June 3, 2019. All per share amounts in this report have been restated to reflect this stock split. An amount equal to the par value of the additional common shares to be issued pursuant to the stock split was reflected as a transfer from retained earnings to common stock on the consolidated financial statements as of and for the three months ended March 31, 2019.

On July 25, 2017, the Company’s Board of Directors authorized the repurchase of up to 2,000,000 common shares through September 30, 2020. The shares buyback plan authorizes management to repurchase the shares at such time as repurchases are considered beneficial to shareholders. Any

9

repurchase of shares 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, 2019, no shares were repurchased under this authorization.

Note 3 – 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, 2019 and 2018, the Company assumes that all dilutive outstanding options to purchase common shares have been exercised at the beginning of the period (or the time of issuance, if later). The dilutive effect of these outstanding options and the restricted shares is reflected by application of the treasury stock method, whereby the proceeds from exercised options and restricted shares are assumed to be used to purchase common shares 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, 2019 and 2018 were 135,494,254 and 135,054,020 shares, respectively. The weighted average common shares outstanding used in computing fully diluted earnings per common share for the three months ended March 31, 2019 and 2018 were 136,286,862 and 135,599,090 shares, respectively. For the three months ended March 31, 2019 and 2018, there were no stock options that were anti-dilutive that have been excluded from the EPS calculation.

Note 4 – Interest-bearing Time Deposits in Banks and Securities

Interest-bearing time deposits in banks totaled $1,458,000 at March 31, 2019 and 2018 and December 31, 2018, respectively, and at March 31, 2019 have original maturities within twelve months.

Management classifies debt and equity securities asheld-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 asheld-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. Debt securities not classified asheld-to-maturity or trading are classified asavailable-for-sale and recorded at 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 debt securities that have unrealized gains and losses are excluded from earnings and reported net of tax in accumulated other comprehensive income until realized. Declines in the fair value ofavailable-for-sale debt securities below their cost that are deemed to be other-than-temporary are reflected in earnings as a realized loss if there is no ability or intent to hold to recovery. If the Company does not intend to sell and will not be required to sell prior to recovery of its amortized cost basis, only the credit component of the impairment is reflected in earnings as a realized loss with the noncredit portion recognized in other comprehensive income. In estimating other-than-temporary impairment losses, we consider (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, and (3) our intent and ability to retain our investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value.

Effective January 1, 2018, in accordance with ASU2016-01 (see note 13), increases or decreases in the fair value of equity securities are recorded in earnings. Prior to January 1, 2018, such increases or decreases were recorded similar to increases or decreases in debt securities.

The Company records itsavailable-for-sale and equity securities portfolio at fair value. 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 debt 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 andheld-to-maturity debt securities are analyzed quarterly for possible other-than-temporary impairment. The analysis considers (i) whether we have the intent to sell our debt securities prior to recovery and/or maturity, (ii) whether it is more likely than not that we will have to sell our debt securities prior to recovery and/or maturity, (iii) the length of time and extent to which the fair value has been less than amortized cost, 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 debt security may be different than previously estimated, which could have a material effect on the Company’s results of operations and financial condition.

The Company’s investment portfolio consists of U.S. Treasury securities, obligations of U.S. government sponsored enterprises and agencies, obligations of state and political subdivisions, 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 value its investment securities, which the Company reviews as well as the underlying pricing methodologies for reasonableness and to ensure such prices are aligned with pricing matrices. The Company validates prices supplied by the independent pricing services by comparison to prices obtained from other third-party sources on a quarterly basis.

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, 2019 were computed by using scheduled amortization of balances and historical prepayment rates. At March 31, 2019 and 2018, and December 31, 2018, the Company did not hold CMOs that entail higher risks than standard mortgage-backed securities.

The number of investments in an unrealized loss position totaled 245 at March 31, 2019. 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 this 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, 2019 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. At March 31, 2019, 84.98% of ouravailable-for-sale securities that are obligations of states and political subdivisions were issued within the State of Texas, of which 33.90% are guaranteed by the Texas Permanent School Fund.

At March 31, 2019, $2,119,995,000 of the Company’s securities were pledged as collateral for public or trust fund deposits, repurchase agreements and for other purposes required or permitted by law.

During the quarters ended March 31, 2019 and 2018, sales of investment securities that were classified asavailable-for-sale totaled $231,000 and $91,445,000, respectively. Gross realized gains from security sales during the first quarter of 2019 and 2018 totaled $4,000 and $1,242,000, respectively. Gross realized losses from security sales during the first quarter of 2019 and 2018 totaled $4,000 and $21,000, respectively.

The specific identification method was used to determine cost in order to compute the realized gains and losses.

Note 5 – Loans Held for Investment 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 an annual basis and makes changes as appropriate. Management receives and reviews monthly reports related to loan originations, quality, concentrations, delinquencies, nonperforming 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.

14

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 within Texas. 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.

The allowance for loan losses is an amount which represents management’s best estimate of probable losses that are inherent in the Company’s loan portfolio as of the balance sheet date. The allowance for loan losses is comprised of three elements: (i) specific reserves determined based on probable losses on specific classified loans; (ii) a historical valuation reserve component that considers historical loss rates and estimated loss emergence periods; and (iii) qualitative reserves 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 bycharge-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 historical valuation reserve, the loan portfolio, less cash secured loans, government guaranteed loans and classified loans, is multiplied by the Company’s historical loss rate adjusted for the estimated loss emergence period. Specific allocations are increased or decreased in accordance with deterioration or improvement in credit quality and a corresponding increase or decrease 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, oil and gas prices, drought conditions, 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 qualitative reserve serves to estimate for additional areas of losses 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 decline in the economy could result in increased levels ofnon-performing assets and charge-offs, increased loan provisions and reductions in income. Additionally, bank regulatory agencies periodically review our allowance for loan losses and methodology and could require, in accordance with U.S. GAAP, additional provisions to the allowance for loan losses based on their judgment of information available to them at the time of their examination as well as changes to our methodology.

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 onnon-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 generallycharged-off when a loan becomes past due 90 days. For other loans in the portfolio, facts and circumstances are evaluated in makingcharge-off decisions.

15

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 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 less cost to sell. Other loan impairments fornon-collateral dependent loans are measured based on the present value of expected future cash flows or the loan’s observable market price. At March 31, 2019 and 2018 and December 31, 2018, 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 less cost to sell.

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. For all impaired loans, including the Company’s troubled debt restructurings, the Company performs a periodic, well-documented credit evaluation of the borrower’s financial condition and prospects for repayment to assess the likelihood that all principal and interest payments required under the terms of the agreement will be collected in full. When doubt exists about the ultimate collectability of principal and interest, the troubled debt restructuring remains onnon-accrual status and payments received are applied to reduce principal to the extent necessary to eliminate such doubt. This determination of accrual status is judgmental and is based on facts and circumstances related to each troubled debt restructuring. Each of these loans is individually evaluated for impairment and a specific reserve is recorded based on probable losses, taking into consideration the related collateral, modified loan terms and cash flow. As of March 31, 2019 and 2018 and December 31, 2018, substantially all of the Company’s troubled debt restructured loans are included in thenon-accrual totals.

Loans acquired, including loans acquired in a business combination, are initially recorded at fair value with no valuation allowance. Acquired loans are segregated between those considered to be credit impaired and those deemed performing. To make this determination, management considers such factors as past due status,non-accrual status and credit risk ratings. The fair value of acquired performing loans is determined by discounting expected cash flows, both principal and interest, at prevailing market interest rates. The difference between the fair value and principal balances at acquisition date, the fair value discount, is accreted into interest income over the estimated life of the acquired portfolio.

Purchased credit impaired loans are those loans that showed evidence of deterioration of credit quality since origination and for which it is probable, at acquisition, that the Company will be unable to collect all amounts contractually owed. Their acquisition fair value, which includes a credit component at the acquisition date, was based on the estimate of cash flows, both principal and interest, expected to be collected or estimated collateral values if cash flows are not estimable, discounted at prevailing market rates of interest. The difference between the discounted cash flows expected at acquisition and the investment in the loan is recognized as interest income on a level-yield method over the life of the loan, unless management was unable to reasonably forecast cash flows in which case the loans were placed on nonaccrual. Subsequent to the acquisition date, increases in expected cash flows will generally result in a recovery of any previously recorded allowance for loan loss, to the extent applicable, and/or a reclassification from the nonaccretable difference to accretable yield, which will be recognized prospectively. Decreases in expected cash flows subsequent to acquisition are recognized as impairment. Valuation allowances on these impaired loans reflect only losses incurred after the acquisition. The carrying amount of purchased credit impaired loans at March 31, 2019 and 2018 and December 31, 2018 were $859,000, $3,201,000 and $827,000, respectively, compared to a contractual balance of $1,196,000, $4,129,000 and $1,157,000, respectively. Other purchased credit impaired loan disclosures were omitted due to immateriality.

The Company recognized interest income on impaired loans prior to being recognized as impaired of approximately $948,000 during the year ended December 31, 2018. Such amounts for the three-month period ended March 31, 2019 and 2018 were not significant.

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

The ratings 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 ouron-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

18

credit as of each 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 onnon-accrual.

During the three months ended March 31, 2019 and 2018, no loans were modified as a troubled debt restructured loan within the previous 12 months and for which there was a payment default. A default for purposes of this disclosure is a troubled debt restructured loan in which the borrower is 90 days past due or more or results in the foreclosure and repossession of the applicable collateral.

As of March 31, 2019, 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 (FHLB) to provide liquidity and meet pledging requirements for those customers eligible to have securities pledged to secure certain uninsured deposits. At March 31, 2019, $2,519,715,000 in loans held by our bank subsidiary were subject to blanket liens as security for this line of credit. At March 31, 2019, there were no advances or letters of credit outstanding under this line of credit.

Note 6 – Loans Held for Sale

The Company originates certain mortgage loans for sale in the secondary market. The mortgage loan sales contracts contain indemnification clauses should the loans default, generally in the first three to nine 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.

Loans held for sale totaled $14,446,000, $17,030,000 and $21,672,000 at March 31, 2019 and 2018, and December 31, 2018, respectively. At March 31, 2019 and December 31, 2018, $2,439,000 and $2,487,000 are valued at the lower of cost or fair value, and the remaining amounts are valued under the fair value option. All of the amounts for March 31, 2018 were valued at the lower of cost or fair value. The change to the fair value option for loans held for sale was effective at June 30, 2018 and was done in conjunction with the Company’s move to mandatory delivery in the secondary market and the purchase of forward mortgage-backed securities to manage the changes in fair value (see note 7 for additional information).

22

These loans, which are sold on a servicing released basis, are valued using a market approach by utilizing either: (i) the fair value of the securities backed by similar mortgage loans, adjusted for certain factors to approximate the fair value of a whole mortgage loan, including the value attributable to mortgage servicing and credit risk, (ii) current commitments to purchase loans or (iii) recent observable market trades for similar loans, adjusted for credit risk and other individual loan characteristics. As these prices are derived from market observable inputs, the Company classifies these valuations as Level 2 in the fair value disclosures (see note 12). Interest income on mortgage loans held for sale is recognized based on the contractual rates and reflected in interest income on loans in the consolidated statements of earnings. The Company has no continuing ownership in any residential mortgage loans sold.

Note 7 – Derivative Financial Instruments

The Company enters into interest rate lock commitments (“IRLCs”) with customers to originate residential mortgage loans at a specific interest rate that are ultimately sold in the secondary market. These commitments, which contain fixed expiration dates, offer the borrower an interest rate guarantee provided the loan meets underwriting guidelines and closes within the timeframe established by the Company.

Beginning in the second quarter of 2018, the Company purchased forward mortgage-backed securities contracts to manage the changes in fair value associated with changes in interest rates related to a portion of the IRLCs. These instruments are typically entered into at the time the IRLC is made.

These financial instruments are not designated as hedging instruments and are used for asset and liability management needs. All derivatives are carried at fair value in either other assets or other liabilities.

The fair values of IRLCs are based on current secondary market prices for underlying loans and estimated servicing value with similar coupons, maturity and credit quality, subject to the anticipated loan funding probability (pull-through rate). The fair value of IRLCs is subject to change primarily due to changes in interest rates and the estimated pull-through rate. These commitments are classified as Level 2 in the fair value disclosures (see note 12), as the valuations are based on observable market inputs.

Forward mortgage-backed securities contracts are exchange-traded or traded within highly active dealer markets. In order to determine the fair value of these instruments, the Company utilizes the exchange price or dealer market price for the particular derivative contract and these instruments are therefore classified as Level 2 in the fair value disclosures (see note 12). The estimated fair values are subject to change primarily due to changes in interest rates.

The following table provides the outstanding notional balances and fair values of outstanding derivative positions (dollars in thousands):

March 31, 2019:	Outstanding Notional Balance		Asset Derivative Fair Value		Liability Derivative Fair Value
IRLCs	$	60,679	$	1,299	$	—
Forward mortgage-backed securities trades		64,500		—		301

March 31, 2018:	Outstanding Notional Balance		Asset Derivative Fair Value		Liability Derivative Fair Value
IRLCs	$	63,090	$	500	$	—

December 31, 2018:	Outstanding Notional Balance		Asset Derivative Fair Value		Liability Derivative Fair Value

Note 8 – Borrowings

Borrowings consisted of the following (dollars in thousands):

	March 31,				December 31,
	2019		2018		2018
Securities sold under agreements with customers to repurchase	$	378,161	$	358,210	$	409,631
Federal funds purchased		4,550		13,945		4,075
Advances from Federal Home Loan Bank of Dallas		—		—		55,000
Total	$	382,711	$	372,155	$	468,706

Securities sold under repurchase agreements are generally with significant customers of the Company that require short-term liquidity for their funds for which the Company pledges certain securities that have a fair value equal to at least the amount of the borrowings. The agreements mature daily and therefore the risk arising from a decline in the fair value of the collateral pledged is minimal. The securities pledged are mortgage-backed securities. These agreements do not include “right ofset-off” provisions and therefore the Company does not offset such agreements for financial reporting purposes.

Note 9 – Income Taxes

Income tax expense was $7,367,000 for the first quarter of 2019 as compared to $6,245,000 for the same period in 2018. The Company’s effective tax rates on pretax income were 16.15% and 15.32% for the three months ended March 31, 2019 and 2018, respectively. The effective tax rates differ from the statutory federal tax rate of 21% primarily 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 excess tax benefits related to our directors’ deferred compensation plan.

24

Note 10 – Stock Option Plan and Restricted Stock Plan

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 were granted in 2018 or through March 31, 2019.

The Company recorded stock option expense totaling $312,000 and $377,000 for the three-month periods ended March 31, 2019 and 2018, respectively. The additional disclosure requirements under authoritative accounting guidance have been omitted due to the amounts being insignificant.

On April 25, 2017, uponre-election of existing directors, 14,650 restricted shares with a total value of $600,000 were granted to the tennon-employee directors and were expensed over the period from the grant date to April 24, 2018, the date of the next annual shareholders’ meeting at which these directors’ term expired. On April 24, 2018, uponre-election of nine of the existing directors, 10,710 restricted shares with a total value of $540,000 were granted to thesenon-employee directors and were expensed over the period from grant date to April 23, 2019, the date of the next annual shareholders’ meeting at which each director’s term expired. The Company recorded director expense related to these restricted share grants of $135,000 and $150,000 for the three-month periods ended March 31, 2019 and 2018, respectively.

On April 23, 2019, uponre-election of nine of the existing directors and two new directors, 10,857 restricted shares with a total value of $660,000 were granted to thesenon-employee directors and will be expensed over the period from the grant date to April 28, 2020, the Company’s next annual shareholders’ meeting at which each director’s term expires.

On October 27, 2015, the Company granted 31,273 restricted shares with a total value of $1,060,000 to certain officers was being expensed over the vesting period of three years. On October 25, 2016, the Company granted 15,405 restricted stock shares with a total value of $560,000 to certain officers that is being expensed over the vesting period of three years. On October 24, 2017, the Company granted 14,191 restricted shares with a total value of $655,000 to certain officers that is being expensed over the vesting period of one to three years. On October 23, 2018, the Company granted 26,021 restricted shares with a total value of $1,440,000 to certain officers that will be expensed over a three-year vesting period. The Company recorded restricted stock expense for officers of $205,000 and $167,000, for the three-month periods ended March 31, 2019 and 2018, respectively.

Note 11 – Pension Plan

The Company’s defined benefit pension plan was frozen effective January 1, 2004, whereby no new participants were added to the plan and no additional years of service were accrued to participants. 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. As a result of its evaluation of its funding status, the Company made no contribution in 2018, and has not made a contribution through March 31, 2019.

In December 2018, due to the rising interest rate environment, the Company determined it was in the best interest of its shareholders to settle its pension obligation to its retiree group in payout, approximately 53% of the pension benefit obligation on that date, and recorded a loss on settlement totaling $1,546,000 for the year ended December 31, 2018. In 2019, the Company began steps to terminate and settle the remaining obligation in its pension plan. The projected plan termination date is June 30, 2019, following which date the Company is obligated to settle the Company’s remaining obligations of the plan upon receipt of regulatory approval. Final settlement of the Company’s remaining obligation under the plan is expected to be made in the first or second quarter of 2020, but is subject to regulatory approval and changes in interest rates so there is some uncertainty as to timing and the amount of funding required to complete final settlement.

25

In addition, the Company had a multiple employer pension plan related to its acquisition of Orange Savings Bank in 2013. This plan is also frozen. During the first quarter of 2019, the Company made a decision to remove this plan from the multiple employer plan and merge it into the Company’s existing pension plan. The Company recorded $900,000 in pension merger expense for the three months ended March 31, 2019 in connection with this merger of the Orange pension plan.

Net periodic benefit costs totaling $923,000 and $56,000 were recorded for the three months ended March 31, 2019 and 2018, respectively, which includes the Orange merger costs discussed above.

Note 12 – 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 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.

26

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 asavailable-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.

See notes 6 and 7 related to the determination of fair value for loansheld-for-sale, IRLCs and forward mortgage-backed securities trades.

There were no transfers between Level 1 and Level 2 or Level 2 and Level 3 during the three months ended March 31, 2019 and 2018, and the year ended December 31, 2018.

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 anon-recurring basis include the following at March 31, 2019:

Impaired Loans – Impaired loans are reported at the fair value of the underlying collateral less selling costs if repayment is expected solely from the collateral. Collateral values are estimated using Level 2 inputs based on observable market data. At March 31, 2019, impaired loans with a carrying value of $15,729,000 were reduced by specific valuation reserves totaling $4,472,000 resulting in a net fair value of $11,257,000. The Company also had impaired loans of $12,779,000 with no specific valuation reserve at March 31, 2019, due to the loans carrying value generally being lower than the value of the collateral associated with the loan.

28

LoansHeld-for-Sale – Loansheld-for-sale are reported at the lower of cost or fair value. The Company originates conforming loans that are sold in the secondary market in which loan pricing is available. These loans are considered Level 2 of the fair value hierarchy. See note 6 related to the determination of fair value. At March 31, 2019, these loans were reported at $2,439,000 and had a fair value of $2,505,000.

IRLC’s and Forward Mortgage-Backed Securities Trades – IRLCs and forward mortgage-backed securities trades are reported at fair value (see note 7).

Certainnon-financial assets andnon-financial liabilities measured at fair value on anon-recurring basis include other real estate owned, goodwill and other intangible assets and othernon-financial long-lived assets.Non-financial assets measured at fair value on anon-recurring basis during the three months ended March 31, 2019 and 2018 include other real estate owned which, subsequent to their initial transfer to other real estate owned from loans, werere-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 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 the above factors but generally range from 5% to 25% of the appraised value.Re-evaluation of other real estate owned is performed at least annually as required by regulatory guidelines or more often if particular circumstances arise. There were no other real estate owned properties that werere-measured subsequent to their initial transfer to other real estate owned during the three months ended March 31, 2019 and 2018.

At March 31, 2019 and 2018, and December 31, 2018, other real estate owned totaled $612,000, $1,179,000 and $448,000, 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. 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 Levels 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.

29

The carrying value and the estimated fair value of the Company’s contractualoff-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.

The estimated fair values and carrying values of all financial instruments under current authoritative guidance, were as follows (in thousands).

Note 13 – Recently Issued Authoritative Accounting Guidance

Accounting Standards Update (“ASU”)2014-09, “Revenue from Contracts with Customers.” ASU2014-09 implemented a comprehensive new revenue recognition standard that supersedes substantially all existing revenue recognition guidance. The new standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity applies the following steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract and (v) recognize revenue when (or as) the entity satisfies a performance obligation. ASU2015-4 “Revenue from Contracts with Customers – Deferral of the Effective Date” deferred the effective date of ASU2014-09 by one year and as a result, the new standard became effective in the first quarter of 2018. The Company’s revenue is comprised of net interest income on financial assets and financial liabilities, which is explicitly excluded from the scope of ASU2014-09, andnon-interest income. The adoption of the new standard in the first quarter of 2018 did not have a significant impact on the Company’s financial statements and no adjustment to opening retained earnings was recorded.

ASU2016-01, ASU2016-01 “Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities.” ASU2016-01, among other things, (i) requires equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income, (ii) simplified the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, (iii) eliminated the requirement for public business entities to disclose the methods and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet, (iv) required public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, (v) required an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments, (vi) required separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements and (vii) clarified that an entity should evaluate the need for a valuation allowance on a deferred tax asset related toavailable-for-sale securities. ASU2016-1 became effective for the Company on January 1, 2018 and did not have a significant impact on the Company’s financial statements.

ASU2016-02, “Leases.” ASU2016-02 amended current lease accounting to require lessees to recognize (i) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis, and (ii) aright-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. ASU2016-02 does not significantly change lease accounting requirements applicable to lessors; however, certain changes were made to align, where necessary, lessor accounting with the lessee accounting model. The amended guidance became effective in the first quarter of 2019 and required transition using a modified retrospective approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The Company evaluated the provisions of the new lease standard and, due to the small dollar amounts and number of lease agreements, the effect for the Company on January 1, 2019 was not significant.

ASU2016-13, “Financial Instruments – Credit Losses.” ASU2016-13 implements a comprehensive change in estimating the allowances for loan losses from the current model of losses inherent in the loan portfolio to a current expected credit loss model that generally is expected to result in earlier recognition of allowances for losses. ASU2016-13 requires a financial asset (or group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The measurement of expected credit losses is based on relevant information about past events, including historical experience,

31

current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. An entity must use judgment in determining the relevant information and estimation methods that are appropriate in its circumstances. Additionally, available for sale debt securities may realize value either through collection of contractual cash flows or through sale of the security at fair value. ASU2016-13 will be effective for the Company as of January 1, 2020. The Company has formed a working group comprised of individuals from various functional areas including credit, risk management, finance and information technology, among others to assist in the implementation of ASU2016-13. The Company is currently working through an implementation plan that includes assessment of processes, portfolio segmentation and model development. Additionally, the Company is working with a third-party vendor to assist with implementation and model development. The Company continues to evaluate the potential impact of ASU2016-13 on the Company’s financial statements.

ASU2017-04, “Intangibles – Goodwill and Other.” ASU2017-04 will amend and simplify current goodwill impairment testing to eliminate Step 2 from the current provisions. Under the new guidance, an entity should perform the goodwill impairment test by comparing the fair value of a reporting unit with its carrying value and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if a quantitative impairment test is necessary. ASU2017-04 will be effective for the Company on January 1, 2020 and is not expected to have a significant impact on the Company’s financial statements.

ASU2017-07, “Compensation – Retirement Benefits, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Post-Retirement Benefit Cost.” ASU2017-17 will require employers that sponsor defined benefit pension plans to present the service cost component of net periodic benefit cost in the same income statement line item as other employee compensation costs arising from services rendered during the period. Other components of the net periodic benefit cost will be presented separately from the service cost component. ASU2017-17 became effective in 2018 and, as the Company froze its defined benefit pension plan in 2004, there is no service cost component of its net periodic benefit cost and therefore did not have an impact on the Company’s financial statements.

ASU2018-02, “Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.”ASU2018-02 was issued to address the income tax accounting treatment of the stranded tax effects within other comprehensive income due to the prohibition of backward tracing due to an income tax rate change that was initially recorded in other comprehensive income. This issue came about from the enactment of the Tax Cuts and Jobs Act on December 22, 2017 that changed the Company’s income tax rate from 35% to 21%. The ASU changed current accounting whereby an entity may elect to reclassify the stranded tax effect from accumulated other comprehensive income to retained earnings. The ASU was effective for periods beginning after December 15, 2018 although early adoption was permitted. The Company early adopted ASU2018-02 in the first quarter of 2018 and reclassified its stranded tax debit of $5,759,000 within accumulated other comprehensive income to retained earnings.

ASU2018-13, “Fair Value Measurement (Topic 820)—Changes to the Disclosure Requirements for Fair Value Measurement” eliminates the requirements to disclose the amount and reason for transfers between Level 1 and Level 2 fair value methodology, the policy for the timing of transfers between levels and the valuation process for Level 3 fair value measurements. ASU2018-13 requires the entity to disclose relevant quantitative information used to develop Level 3 fair value measurements. ASU2018-13 will become effective for the Company on January 1, 2020 and is not expected to have a significant impact on the Company’s financial statements.

ASU2018-14, “Compensation – Retirement Benefit Plans – General (Subtopic715-20).”ASU2018-14 changes the disclosure requirement for employers that sponsor defined benefit pension and/or other post- retirement benefit plans, eliminating certain disclosures no longer considered cost beneficial and requiring new disclosures now considered more pertinent. ASU2018-14 will be effective for the year ending December 31, 2020.

Note 14 – Acquisition

On October 12, 2017, we entered into an agreement and plan of reorganization to acquire Commercial Bancshares, Inc. and its wholly owned bank subsidiary, Commercial State Bank, Kingwood, Texas. On January 1, 2018, the transaction was completed. Pursuant to the agreement, we issued 1,289,371 shares of the Company’s common stock in exchange for all of the outstanding shares of Commercial Bancshares, Inc. In addition, Commercial Bancshares, Inc. made a $22,075,000 special dividend to its shareholders prior to closing of the transaction, which was increased for the amount by which Commercial Bancshares, Inc.’s consolidated shareholders’ equity as of January 1, 2018 exceeded $42,402,000, after certain adjustments per the merger agreement.

At closing, Commercial Bancshares, Inc. was merged into the Company and Commercial State Bank, Kingwood, Texas, was merged into First Financial Bank, National Association, Abilene, Texas, a wholly owned subsidiary of the Company. The primary purpose of the acquisition was to expand the Company’s market share around Houston. Factors that contributed to a purchase price resulting in goodwill include Commercial State Bank’s record of earnings, strong management and board of directors, strong local economic environment and opportunity for growth. The results of operations from this acquisition are included in the consolidated earnings of the Company commencing January 1, 2018.

The following table presents the amounts recorded on the consolidated balance sheet on the acquisition date (dollars in thousands):

Fair value of consideration paid:
Common stock issued (1,289,371 shares)	$	58,087
Fair value of identifiable assets acquired:
Cash and cash equivalents		18,653
Securities available-for-sale		64,501
Loans		266,327
Identifiable intangible assets		3,167
Other assets		15,375
Total identifiable assets acquired		368,023
Fair value of liabilities assumed:
Deposits		341,902
Other liabilities		(373	)
Total liabilities assumed		341,529
Fair value of net identifiable assets acquired		26,494
Goodwill resulting from acquisition	$	31,593

Goodwill recorded in the acquisition was accounted for in accordance with the authoritative business combination guidance. Accordingly, goodwill will not be amortized but will be tested for impairment annually. The goodwill recorded is not deductible for federal income tax purposes.

The fair value of total loans acquired was $266,327,000 at acquisition compared to contractual amounts of $271,714,000. The fair value of purchased credit impaired loans at acquisition was $3,013,000 compared to contractual amounts of $3,806,000. Additional purchased credit impaired loan disclosures were omitted due to immateriality. All other acquired loans were considered performing loans.

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, First Financial Bank, National Association, Abilene, Texas. Our largest expense is 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 and analysis of operations and financial condition should be read in conjunction with the financial statements and accompanying footnotes included in Item 1 of this Form10-Q as well as those included in the Company’s 2018 Annual Report on Form10-K.

Critical Accounting Policies

We prepare consolidated financial statements based on GAAP 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 5 and note 4, respectively, to our notes to consolidated financial statements (unaudited) which begins on page 9.

Stock Split

On April 23, 2019, the Company’s Board of Directors declared atwo-for-one stock split in the form of a 100% stock dividend effective for shareholders of record on May 15, 2019 to be distributed on June 3, 2019. All per share amounts in this report have been restated to reflect this stock split. An amount equal to the par value of the additional common shares to be issued pursuant to the stock split was reflected as a transfer from retained earnings to common stock on the consolidated financial statements as of and for the three months ended March 31, 2019.

Developments

Acquisition

On October 12, 2017, we entered into an agreement and plan of reorganization to acquire Commercial Bancshares, Inc. and its wholly-owned bank subsidiary, Commercial State Bank, Kingwood, Texas. On January 1, 2018, the transaction closed. Pursuant to the agreement, we issued 1,289,371 shares of the Company’s common stock in exchange for all of the outstanding shares of Commercial Bancshares, Inc. In addition, in accordance with the plan of reorganization, Commercial Bancshares, Inc. paid a special dividend totaling $22.08 million to its shareholders prior to the closing of this transaction. At the closing, Kingwood Merger Sub., Inc., a wholly-owned subsidiary of the Company, merged into Commercial Bancshares Inc., with Commercial Bancshares, Inc. surviving as a wholly-owned subsidiary of the Company. Immediately following such merger, Commercial Bancshares, Inc. was merged into the Company and Commercial State Bank, Kingwood, Texas was merged into First Financial Bank, National Association, Abilene, Texas, a wholly owned subsidiary of the Company. The total purchase price exceeded the estimated fair value net of assets acquired by approximately $31.59 million and the Company recorded such excess as goodwill. The balance sheet and results of operations of Commercial Bancshares, Inc. have been included in the financial statements of the Company effective January 1, 2018. See note 14 to the consolidated financial statements on page 33 for additional information and disclosure.

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 $71.33 million for the first quarter of 2019, as compared to $67.92 million for the same period last year. The increase in 2019 compared to 2018 was largely attributable to the increase in interest earning assets. Average earning assets increased $135.78 million for the first quarter of 2019 over the same period in 2018. Average loans and taxable securities increased $224.55 million and $98.47 million, respectively, for the first quarter of 2019 over the same quarter of 2018.Averagetax-exempt securities decreased $125.78 million for the first quarter of 2019 compared to the same period in 2018, primarily due to the Company’s gradual shift away fromtax-exempt securities due to the change in corporate tax rate to 21% from 35%. Average interest-bearing liabilities increased $55.99 million for the first quarter of 2019, as compared to the same period in 2018. The yield on earning assets increased 33 basis points while the rate paid on interest-bearing liabilities increased 33 basis points for the first quarter of 2019 compared to the first quarter of 2018.

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

The net interest margin for the first quarter of 2019 was4.00%, an increase of twelve basis points from the same period in 2018. We continue to experience downward pressures on our net interest margin in 2019 and 2018 primarily due to (i) the change in the income tax rate from 35% to 21% from the Tax Cuts and Jobs Act and its effect on our tax free municipal bonds and tax free loans and (ii) the result of the extended period of historically low levels of short-term interest rates, although rates did increase somewhat in the past 24 months. We have been able to somewhat mitigate the impact of lower short-term interest rates by establishing minimum interest rates on certain of our loans, improving the pricing for loan risk, and minimizing rates paid on interest bearing liabilities. As rates have begun to increase, we are adjusting loan rates upon maturities and converting to variable rates when we are able. We have also begun increasing rates paid on our interest-bearing deposits. The Federal Reserve increased rates 100 basis points in 2018, 75 basis points in 2017 and 25 basis points in 2016 and 2015, however recent forward guidance from the Federal Reserve indicated no increases in 2019.

The net interest margin, which measurestax-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 2019 increased to $24.44 million compared to $24.42 million in same period in 2018. Trust fees increased to $6.98 million in the first quarter of 2019 compared with $6.90 million in the same quarter last year, due to continued growth in the fair value of trust assets managed to $6.06 billion from $5.23 billion a year ago. Service charges on deposit accounts increased 5.98% to $5.18 million compared with $4.88 million in the same quarter last year primarily due to continued growth in net new accounts. Real estate mortgage fees increased in the first quarter of 2019 to $3.47 million compared with $2.93 million in the same quarter a year ago due to increased value of loans originated and additional income from the change to mandatory delivery related to sales in the secondary mortgage market (see notes 6 and 7 to the consolidated financial statements (unaudited) on pages 22 to 24). Offsetting these increases were decreases in gains on the sale of securities of $1.22 million compared to the same quarter in 2018.

ATM and interchange fees are charges that merchants pay to us and other card-issuing banks for processing electronic payment transactions. ATM and interchange fees consist of income from debit card usage, point of sale income for debit card transactions and ATM service fees. Federal Reserve rules applicable to financial institutions that have assets of $10 billion or more provide that the maximum permissible interchange fee for an electronic debit transaction is the sum of 21 cents per transaction and 5 basis points multiplied by the value of the transaction. While we currently have assets under $10 billion, we are monitoring the effect of this reduction in per transaction fee income as we approach the $10 billion asset level.

Noninterest Expense. Total noninterest expense for the first quarter of 2019 was $47.37 million, a decrease of $431 thousand compared to $47.80 million in the same period of 2018. An important measure in determining whether a financial institution effectively manages noninterest expense is the efficiency ratio, which is calculated by dividing noninterest expense by the sum of net interest income on atax-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 2019 was 49.46% compared to 51.76% for the same period in 2018.

39

Salaries and employee benefits for the first quarter of 2019 totaled $27.42 million, an increase of $1.22 million compared to the same period in 2018. The increase was primarily driven by (i) annual merit-based pay increases that were effective March 1, 2019, (ii) an increase in our profit sharing expenses of $282 thousand over the same quarter in 2018 and (iii) the recognition of $900 thousand resulting from the Company’s continued efforts to terminate its frozen defined benefit pension plan. All other categories of noninterest expense for the first quarter of 2019 totaled $19.94 million, down from $21.59 million when compared to the same quarter in 2018, primarily related to the Company recording $1.55 million in the first quarter of 2018 related to contract termination and conversion costs associated with the Kingwood acquisition.

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 for1-4 family residences and commercial real estate. The structure of loans in the real estate mortgage area generally providesre-pricing intervals to minimize the interest rate risk inherent in long-term fixed rate loans. As of March 31, 2019, total loans held for investment were $3.99 billion, an increase of $35.52 million, as compared to December 31, 2018 balances. As compared to December 31, 2018, commercial loans decreased $18.07 million, agricultural loans decreased $5.34 million, real estate loans increased $44.86 million and consumer loans increased $14.07 million. Loans averaged $3.97 billion during the first quarter of 2019, an increase of $224.55 million from the prior year first quarter average balances.

Total loansheld-for-investment	$	3,989,160	$	3,730,051	$	3,953,636

At March 31, 2019, our real estate loans represent approximately 67.29% of our loan portfolio and are comprised of (i)1-4 family residence loans of 41.73%, (ii) commercial real estate loans of 29.77%, generally owner occupied, (iii) other loans, which includes ranches, hospitals and universities, of 13.34%, (iv) residential development and construction loans of 10.06%, which includes our custom and speculative home construction loans and (v) commercial development and construction loans of 5.10%.

Loans held for sale, consisting of secondary market mortgage loans, totaled $14.45 million, $17.03 million, and $21.67 million at March 31, 2019 and 2018, and December 31, 2018, respectively. At March 31, 2019 and December 31, 2018, $2.44 million and $2.49 million, respectively, are valued using the lower of cost or fair value method and the remaining amount is valued under the fair value option method. All of the loans held for sale at March 31, 2018 were valued at the lower of cost or fair value. See notes 6 and 7 to the consolidated financial statements (unaudited) related to the change to mandatory delivery for sales in the secondary mortgage market on pages 22 through 24.

Asset Quality. Our loan portfolio is subject to periodic reviews by our centralized independent loan review group as well as periodic examinations by 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 or more and still accruing, and restructured loans plus foreclosed assets were $29.72 million at March 31, 2019, as compared to $24.87 million at March 31, 2018 and $29.63 million at December 31, 2018. As a percent of loans and foreclosed assets, these assets were 0.74% at March 31, 2019, as compared to 0.75% at December 31, 2018 and 0.66% at March 31, 2018. As a percent of total assets, these assets were 0.37% at March 31, 2019, as compared to 0.38% at December 31, 2018 and 0.33% at March 31, 2018. We believe the level of these assets to be manageable and are not aware of any material classified credits not properly disclosed as nonperforming at March 31, 2019.

Supplemental Oil and Gas Information. As of March 31, 2019, the Company’s exposure to the oil and gas industry totaled 2.68% of gross loans, or $107.34 million, down $6.20 million from December 31, 2018year-end levels, and consisted (based on collateral supporting the loan) of (i) development and production loans of 0.31%, (ii) oil and gas field servicing loans of 10.19%, (iii) real estate loans of 43.25%, (iv) accounts receivable and inventory of 2.25%, (v) automobile of 38.17% and (vi) other of 5.83%.

* Includes $859 thousand, $3.20 million and $827 thousand of purchased credit impaired loans as of March 31, 2019 and 2018, and December 31, 2018, respectively.

** Other troubled debt restructured loans of $4.57 million, $4.61 million and $3.84 million, whose interest collection, after considering economic and business conditions and collection efforts, is doubtful are included innon-accrual loans at March 31, 2019 and 2018, and December 31, 2018, respectively.

We record interest payments received onnon-accrual loans as reductions of principal. Prior to the loans being placed onnon-accrual, we recognized interest income on impaired loans of approximately $395 thousand for the year ended December 31, 2018. If interest on these impaired loans had been recognized on a full accrual basis during the year ended December 31, 2018, such income would have approximated $2.57 million. Such amounts for the 2019 and 2018 interim periods were not significant.

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 5 to our notes to the consolidated financial statements (unaudited). The provision for loan losses was $965 thousand for the first quarter of 2019, as compared to $1.31 million for the first quarter of 2018. The continued provision for loan losses in 2019 and 2018 reflects primarily the growth in the loan portfolio. As a percent of average loans, net loan charge-offs were 0.06% for the first quarter of 2019, as compared to 0.00% for the first quarter of 2018. The allowance for loan losses as a percent of loans was 1.29% as of March 31, 2019, as compared to 1.32% as of March 31, 2018 and 1.29% as of December 31, 2018. Included in Table 7 is further analysis of our allowance for loan losses.

Interest-Bearing Deposits in Banks. At March 31, 2019, our interest-bearing deposits in banks were $199.22 million compared to $68.52 million at March 31, 2018 and $42.27 million at December 31, 2018, respectively. At March 31, 2019, interest-bearing deposits in banks included $1.46 million invested in FDIC-insured certificates of deposit, $196.93 million maintained at the Federal Reserve Bank of Dallas and $827 thousand on deposit with the Federal Home Loan Bank of Dallas (“FHLB”).

Available-for-Sale andHeld-to-Maturity Securities. At March 31, 2019, securities with a fair value of $3.21 billion were classified as securitiesavailable-for-sale. As compared to December 31, 2018, theavailable-for-sale portfolio at March 31, 2019reflected (i) an increase in U.S. Treasury securities of $29 thousand, (ii) a decrease of $301 thousand in obligations of U.S. government sponsored enterprises and agencies, (iii) a decrease of $18.14 million in obligations of states and political subdivisions, (iv) an increase of $61 thousand in corporate bonds and other, and (v) an increase of $72.39 million in mortgage-backed securities. The shift to mortgage-backed securities from obligations of state and political subdivisions was due to the change in the federal income tax rate of 21% from 35% effective January 1, 2018. Our mortgage related securities are backed by GNMA, FNMA or FHLMC or are collateralized by securities backed by these agencies.

See note 4 to the consolidated financial statements (unaudited) for additional disclosures relating to the investment portfolio at March 31, 2019 and 2018, and December 31, 2018.

All yields are computed on atax-equivalent basis assuming a marginal tax rate of 21%. Yields onavailable-for-sale 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 earlier of maturity date or call date.

As of March 31, 2019, the investment portfolio had an overall tax equivalent yield of 3.33%, a weighted average life of 4.49 years and modified duration of 3.97 years.

Deposits. Deposits held by our subsidiary bank represent our primary source of funding. Total deposits were $6.35 billion as of March 31, 2019, as compared to $6.19 billion as of March 31, 2018 and $6.18 billion as of December 31, 2018. Table 9 provides a breakdown of average deposits and rates paid for the three month period ended March 31, 2019 and 2018, respectively.

Borrowings.Included in borrowings were federal funds purchased, securities sold under repurchase agreements and advances from the FHLB of $382.71 million, $372.16 million and $468.71 million at March 31, 2019 and 2018 and December 31, 2018, respectively. Securities sold under repurchase agreements are generally with significant customers of the Company that require short-term liquidity for their funds for which we pledge certain securities that have a fair value equal to at least the amount of the borrowings. The average balance of federal funds purchased, securities sold under repurchase agreements and advances from the FHLB were $408.64 million and $357.41 million in the first quarter of 2019 and 2018, respectively. The weighted average interest rates paid on these borrowings were 0.72% and 0.13% for the first quarters of 2019 and 2018, 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 $1.11 billion, or 13.94% of total assets at March 31, 2019, as compared to $969.81 million, or 12.82% of total assets at March 31, 2018 and $1.05 billion, or 13.62% of total assets at December 31, 2018. Included in shareholders’ equity at March 31, 2019 and 2018 and December 31, 2018, were $31.83 million, $724 thousand and $4.17 million, respectively, in unrealized gains (losses) on investment securitiesavailable-for-sale, net of related income taxes. For the first quarter of 2019, total shareholders’ equity averaged $1.07 billion or 13.82% of average assets, as compared to $950.05 million, or 12.52% of average assets, during the same period in 2018.

Banking regulators measure capital adequacy by means of the risk-based capital ratios and the leverage ratio under the Basel III regulatory capital framework and prompt corrective action regulations. The risk-based capital rules provide for the weighting of assets andoff-balance-sheet commitments and contingencies according to prescribed risk categories. 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 byquarter-to-date average assets less intangible assets.

Beginning in January 2016, under the Basel III regulatory capital framework, the implementation of the capital conservation buffer was effective for the Company starting at the 0.625% level and increasing 0.625% each year thereafter, until it reached 2.5% on January 1, 2019. The capital conservation buffer is designed to absorb losses during periods of economic stress and requires increased capital levels for the purpose of capital distributions and other payments. Failure to meet the amount of the buffer will result in restrictions on the Company’s ability to make capital distributions, including dividend payments and stock repurchases, and to pay discretionary bonuses to executive officers.

As of March 31, 2019 and 2018, and December 31, 2018, we had a total capital to risk-weighted assets ratio of 21.00%, 19.58% and 20.61%, a Tier 1 capital to risk-weighted assets ratio of 19.86%, 18.43% and 19.47%; a common equity Tier 1 to risk-weighted assets ratio of 19.86%, 18.43% and 19.47% and a leverage ratio of 12.08%, 10.90% and 11.85%, respectively. The regulatory capital ratios as of March 31, 2019 and 2018, and December 31, 2018 were calculated under Basel III rules. There is no threshold for well-capitalized status for bank holding companies.

In connection with the adoption of the Basel III regulatory capital framework, our subsidiary bank made the election to continue to exclude most accumulated other comprehensive income (“AOCI”) from capital in connection with its quarterly financial filing and, in effect, to retain the AOCI treatment under the prior capital rules.

Interest Rate Risk

Interest rate risk results when the maturity or repricing 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 nooff-balance sheet financial instruments to manage 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 there-pricing and maturity characteristics of the existing and projected balance sheet.

As of March 31, 2019, the model simulations projected that 100 and 200 basis point increases in interest rates would result in positive variances in net interest income of 2.77% and 4.97%, respectively, relative to the current financial statement structure over the next twelve months, while a decrease in interest rates of 100 and 200 basis points would result in a negative variance in net interest income of 2.88% and 7.33%, respectively, relative to the current financial statement structure over the next twelve months. Our model simulation as of March 31, 2019 indicates that our balance sheet is relatively asset/liability neutral. These are good faith estimates and assume that the composition of our interest sensitive assets and liabilities existing at eachperiod-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 on specific assets or liabilities. Also, this analysis does not contemplate any actions that we might undertake

47

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 liabilitiesre-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 repricing 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 bank. Other sources of funds include our ability to borrow from short-term sources, such as purchasing federal funds from correspondent banks, sales of securities under agreements to repurchase and advances from the FHLB (see below) and an unfunded $25.00 million revolving line of credit established with Frost Bank, a nonaffiliated bank, which matures in June 2019 (see next paragraph).Our subsidiary bank also has federal funds purchased lines of credit with twonon-affiliated banks totaling $130.00 million. At March 31, 2019, no amounts were drawn on these lines of credit. Our subsidiary bank also has available a line of credit with the FHLB totaling $1.25 billion, at March 31, 2019, secured by portions of our loan portfolio and certain investment securities. At March 31, 2019, the Company had no advances or letters of credit outstanding under this line of credit.

The Company renewed its loan agreement, effective June 30, 2017, with Frost Bank. Under the loan agreement, as renewed and amended, we are permitted to draw up to $25.00 million on a revolving line of credit. Prior to June 30, 2019, interest is paid quarterly atThe Wall Street Journal Prime Rate and the line of credit matures June 30, 2019. If a balance exists at June 30, 2019, the principal balance converts to a term facility payable quarterly over five years and interest is paid quarterly at our election atThe Wall Street Journal Prime Rate 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 ratios. 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. The Company was in compliance with the financial and operational covenants at March 31, 2019. There was no outstanding balance under the line of credit as of March 31, 2019 or December 31, 2018.

48

In addition, we anticipate that future acquisitions of financial institutions, expansion of branch locations or offerings of new products could also place a demand on our cash resources. Available cash and cash equivalents at our parent company which totaled $89.23 million at March 31, 2019, investment securities which totaled $6.33 million at March 31, 2019 and mature over 9 to 12 years, available dividends from our subsidiaries which totaled $212.15 million at March 31, 2019, 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.

Our liquidity position is continuously monitored and adjustments are made to the balance between sources and uses of funds as deemed appropriate. Liquidity risk management is an important element in our asset/liability management process. We regularly model liquidity stress scenarios to assess potential liquidity outflows or funding problems resulting from economic disruptions, volatility in the financial markets, unexpected credit events or other significant occurrences deemed potentially problematic by management. These scenarios are incorporated into our contingency funding plan, which provides the basis for the identification of our liquidity needs. As of March 31, 2019, management is not aware of any events that are reasonably likely to have a material adverse effect on our liquidity, capital resources or operations. Given the strong core deposit base and relatively low loan to deposit ratios maintained at our subsidiary bank, we consider our current liquidity position to be adequate to meet our short-term and long-term liquidity needs. In addition, management is not aware of any regulatory recommendations regarding liquidity that would have a material adverse effect on us.

Off-Balance Sheet Arrangements. We are a party to financial instruments withoff-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 to correspondent banks 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 foron-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 acase-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, 2019 (in thousands):

	Total Notional Amounts Committed
Unfunded lines of credit	$	620,368
Unfunded commitments to extend credit		339,441
Standby letters of credit		30,151
Total commercial commitments	$	989,960

We believe we have no otheroff-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, 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 intercompany dividends 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, 2019, approximately $212.15 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 $2.0 million and $1.80 million for the three-month periods ended March 31, 2019 and 2018, respectively.

Dividends. Our long-term dividend policy is to pay cash dividends to our shareholders of approximately 40% of annual net earnings while maintaining adequate capital to support growth. We are also restricted by a loan covenant within our line of credit agreement with Frost Bank to dividend no greater than 55% of net income, as defined in such loan agreement. The cash dividend payout ratios have amounted to 37.24% and 36.47% of net earnings for the first three months of 2019 and 2018, respectively. 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, which is a national banking association and a member of the Federal Reserve System, is required by federal law to obtain the prior approval of 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.

To pay dividends, we and our subsidiary bank must maintain adequate capital above regulatory guidelines. In addition, if the applicable regulatory authority believes that a bank 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 bank, 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, 2019, 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 (as defined in Rule13a-15(e) or15d-15(e) 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, and 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 control. 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 become inadequate because of changes in conditions or the degree of compliance with the 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 were effective at the reasonable assurance level as of March 31, 2019.

Subsequent to our evaluation, there were no significant changes in internal controls over financial reporting or other factors that have materially affected, or are reasonably likely to materially affect, these internal controls.
