Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: Nature of Operations First Financial Bankshares, Inc. (a Texas corporation) (“Bankshares”, “Company”, “we” or “us”) is a financial holding company which owns all of the capital stock of one bank with 70 locations located in Texas as of December 31, 2015. The subsidiary bank is First Financial Bank, National Association, Abilene. The bank’s primary source of revenue is providing loans and banking services to consumers and commercial customers in the market area in which the subsidiary is located. In addition, the Company also owns First Financial Trust & Asset Management Company, National Association, First Financial Insurance Agency, Inc., and First Technology Services, Inc. A summary of significant accounting policies of Bankshares and subsidiaries applied in the preparation of the accompanying consolidated financial statements follows. The accounting principles followed by the Company and the methods of applying them are in conformity with both U.S. generally accepted accounting principles and prevailing practices of the banking industry. The Company evaluated subsequent events for potential recognition through the date the consolidated financial statements were issued. Use of Estimates in Preparation of Financial Statements The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The Company’s significant estimates include its allowance for loan losses and its valuation of financial instruments. Consolidation The accompanying consolidated financial statements include the accounts of Bankshares and its subsidiaries, all of which are wholly-owned. All significant intercompany accounts and transactions have been eliminated. Stock Repurchase On October 28, 2014, the Company’s Board of Directors authorized the repurchase of up to 1,500,000 common shares through September 30, 2017. The stock buyback plan authorizes management to repurchase the stock at such time as repurchases are considered beneficial to stockholders. Any repurchase of stock will be made through the open market, block trades or in privately negotiated transactions in accordance with applicable laws and regulations. Under the repurchase plan, there is no minimum number of shares that the Company is required to repurchase. For the years ended December 31, 2015, 2014 and 2013, no shares were repurchased under this or the prior authorization that expired September 30, 2014. Stock Split On April 22, 2014, the Company’s Board of Directors declared a two-for-one stock split in the form of a 100% stock dividend effective for shareholders of record on May 15, 2014 that was distributed on June 2, 2014. All share and 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 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 year ended December 31, 2014. Acquisitions and Asset Purchase On July 31, 2015, the Company acquired 100% of the outstanding capital stock of FBC Bancshares, Inc. through the merger of a wholly-owned subsidiary with and into FBC Bancshares, Inc. Following such merger, FBC Bancshares, Inc. and its wholly-owned subsidiary, First Bank, N.A. were merged into the Company and First Financial Bank, National Association, respectively. The results of operations of FBC Bancshares, Inc. subsequent to the acquisition date, are included in the consolidated earnings of the Company. See Note 18 for additional information. On June 1, 2015, the Company completed the asset purchase of 4Trust Mortgage, Inc. The results of operation of 4Trust Mortgage Inc. subsequent to the asset purchase date, are included in the consolidated earnings of the Company. See Note 18 for additional information. On May 31, 2013, the Company acquired 100% of the outstanding capital stock of Orange Savings Bank, SSB, a wholly-owned subsidiary of OSB Financial Services, Inc., through the merger of Orange Savings Bank, SSB with and into First Financial Bank, National Association. The results of operations of Orange Savings Bank, SSB, subsequent to the acquisition date, are included in the consolidated earnings of the Company. See Note 18 for additional information. Increase in Authorized Shares On April 28, 2015, the Company’s shareholders approved an amendment to the Company’s Amended and Restated Certificate of Formation to increase the number of authorized common shares to 120,000,000. Investment Securities Management classifies debt and equity securities as held-to-maturity, available-for-sale, or trading based on its intent. Debt securities that management has the positive intent and ability to hold to maturity are classified as held-to-maturity and recorded at cost, adjusted for amortization of premiums and accretion of discounts, which are recognized as adjustments to interest income using the interest method. Securities not classified as held-to-maturity or trading are classified as available-for-sale and recorded at fair value, with all unrealized gains and unrealized losses judged to be temporary, net of deferred income taxes, excluded from earnings and reported in the consolidated statements of comprehensive earnings. Available-for-sale securities that have unrealized losses that are judged other-than-temporary are included in gain (loss) on sale of securities and a new cost basis is established. Securities classified as trading are recorded at fair value with unrealized gains and losses included in earnings. The Company records its available-for-sale and trading 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 security is below its amortized cost, and depending on the length of time the condition exists and the extent the fair value is below amortized cost, additional analysis is performed to determine whether an other-than-temporary impairment condition exists. Available-for-sale and held-to-maturity securities are analyzed quarterly for possible other-than-temporary impairment. The analysis considers (i) whether we have the intent to sell our securities prior to recovery and/or maturity, (ii) whether it is more likely than not that we will have to sell our securities prior to recovery and/or maturity, (iii) the length of time and extent to which the fair value has been less than 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 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 quarterly, on a sample basis, prices supplied by the independent pricing services by comparison to prices obtained from other third party sources. Loans and Allowance for Loan Losses Loans held for investment are stated at the amount of unpaid principal, reduced by unearned income and an allowance for loan losses. Interest on loans is calculated by using the simple interest method on daily balances of the principal amounts outstanding. The Company defers and amortizes net loan origination fees and costs as an adjustment to yield. The allowance for loan losses is established through a provision for loan losses charged to expense. Loans are charged against the allowance for loan losses when management believes the collectability of the principal is unlikely. The 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 (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 by charge-offs (net of recoveries). Management’s periodic evaluation of the appropriateness of the allowance is based on general economic conditions, the financial condition of borrowers, the value and liquidity of collateral, delinquency, prior loan loss experience, and the results of periodic reviews of the portfolio. For purposes of determining our 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. 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 downturn in the economy and employment could result in increased levels of non-performing assets and charge-offs, increased loan provisions and reductions in income. Additionally, bank regulatory agencies periodically review our allowance for loan losses and methodology and could require, in accordance with generally accepted accounting principles, 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 on non-accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Consumer loans are generally charged-off when a loan becomes past due 90 days. For other loans in the portfolio, facts and circumstances are evaluated in making charge-off decisions. Loans are considered impaired when, based on current information and events, management determines that it is probable we will be unable to collect all amounts due in accordance with the loan agreement, including scheduled principal and interest payments. If a loan is impaired, a specific valuation allowance is allocated, if necessary. Interest payments on impaired loans are typically applied to principal unless collectability of the principal amount is reasonably assured, in which case interest is recognized on a cash basis. Impaired loans, or portions thereof, are charged off when deemed uncollectable. The Company’s policy requires measurement of the allowance for an impaired, collateral dependent loan based on the fair value of the collateral. Other loan impairments for non-collateral dependent loans are measured based on the present value of expected future cash flows or the loan’s observable market price. At December 31, 2015 and 2014, 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. 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 on non-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 December 31, 2015 and 2014, substantially all of the Company’s troubled debt restructured loans are included in the non-accrual totals. The Company originates certain mortgage loans for sale in the secondary market. Accordingly, these loans are classified as held-for-sale and are carried at the lower of cost or fair value on an aggregate basis. The mortgage loan sales contracts contain indemnification clauses should the loans default, generally in the first three to six months, or if documentation is determined not to be in compliance with regulations. The Company’s historic losses as a result of these indemnities have been insignificant. 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 each loan. 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. Contractually required payments for interest and principal that exceed the cash flows expected at acquisition are not recognized as a yield adjustment. Increases in expected cash flows subsequent to the initial investment are recognized prospectively through adjustment of the yield on the loan over its remaining life. 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 December 31, 2015 and 2014 were $2,178,000 and $2,151,000, respectively, compared to a contractual balance of $2,936,000 and $3,275,000, respectively. Other purchased credit impaired loan disclosures were omitted due to immateriality. Other Real Estate Other real estate owned is foreclosed property held pending disposition and is initially recorded at fair value, less estimated costs to sell. At foreclosure, if the fair value of the real estate, less estimated costs to sell, is less than the Company’s recorded investment in the related loan, a write-down is recognized through a charge to the allowance for loan losses. Any subsequent reduction in value is recognized by a charge to income. Operating and holding expenses of such properties, net of related income, and gains and losses on their disposition are included in net gain (loss) on sale of foreclosed assets as incurred. Bank Premises and Equipment Bank premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are computed principally on a straight-line basis over the estimated useful lives of the related assets. Leasehold improvements are amortized over the life of the respective lease or the estimated useful lives of the improvements, whichever is shorter. Business Combinations, Goodwill and Other Intangible Assets The Company accounts for all business combinations under the purchase method of accounting. Tangible and intangible assets and liabilities of the acquired entity are recorded at fair value. Intangible assets with finite useful lives represent the future benefit associated with the acquisition of the core deposits and are amortized over seven years, utilizing a method that approximates the expected attrition of the deposits. Goodwill with an indefinite life is not amortized, but rather tested annually for impairment as of June 30 each year and totaled $139,971,000 and $94,882,000 at December 31, 2015 and 2014, respectively. There was no impairment recorded for the years ended December 31, 2015, 2014 and 2013. The carrying amount of goodwill arising from acquisitions that qualify as an asset purchase for federal income tax purposes was $74,376,000 and $72,626,000, respectively, at December 31, 2015 and 2014, and is deductible for federal income tax purposes. Also included in other intangible assets are mortgage servicing rights totaling $1,902,000 and $1,834,000 at December 31, 2015 and 2014, respectively. Securities Sold Under Agreements To Repurchase Securities sold under agreements to repurchase, which are classified as borrowings, generally mature within one to four days from the transaction date. Securities sold under agreements to repurchase are reflected at the amount of the cash received in connection with the transaction. The Company may be required to provide additional collateral based on the estimated fair value of the underlying securities. Segment Reporting The Company has determined that its banking regions meet the aggregation criteria of the current authoritative accounting guidance since each of its banking regions offer similar products and services, operate in a similar manner, have similar customers and report to the same regulatory authority, and therefore operate one line of business (community banking) located in a single geographic area (Texas). Statements of Cash Flows For purposes of reporting cash flows, cash and cash equivalents includes cash on hand, amounts due from banks, including interest-bearing deposits in banks with original maturity of 90 days or less, and federal funds sold. Accumulated Other Comprehensive Income (Loss) Unrealized net gains on the Company’s available-for-sale securities (after applicable income tax expense) totaling $51,359,000 and $50,162,000 at December 31, 2015 and 2014, respectively, and the minimum pension liability totaled (after applicable income tax benefit) totaling $3,964,000 and $2,673,000 at December 31, 2015 and 2014, respectively, are included in accumulated other comprehensive income. Income Taxes The Company’s provision for income taxes is based on income before income taxes adjusted for permanent differences between financial reporting and taxable income. Deferred tax assets and liabilities are determined using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is determined based on the tax effects of the temporary differences between the book and tax bases of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws. Stock Based Compensation The Company grants stock options for a fixed number of shares to employees with an exercise price equal to the fair value of the shares at the grant date. The Company recorded stock option expense totaling $644,000, $709,000 and $411,000 for the years ended December 31, 2015, 2014 and 2013, respectively. The Company also grants restricted stock for a fixed number of shares. The Company recorded expenses associated with its director and officer restricted stock grants totaling $139,000 and $62,000, respectively, for the year ended December 31, 2015. As the restricted stock plans were approved by shareholders in April 2015, there were no such expenses in 2014 and 2013. Advertising Costs Advertising costs are expensed as incurred. Per Share Data Net earnings per share (“EPS”) are computed by dividing net earnings by the weighted average number of common stock shares outstanding during the period. The Company calculates dilutive EPS assuming all outstanding options to purchase common stock have been exercised at the beginning of the year (or the time of issuance, if later.) The dilutive effect of the outstanding options is reflected by application of the treasury stock method, whereby the proceeds from the exercised options are assumed to be used to purchase common stock at the average market price during the period. The following table reconciles the computation of basic EPS to dilutive EPS: Net Weighted Per Share For the year ended December 31, 2015: Net earnings per share, basic $ 100,381 64,892,934 $ 1.55 Effect of stock options and stock grants — 175,096 (0.01 ) Net earnings per share, assuming dilution $ 100,381 65,068,030 $ 1.54 For the year ended December 31, 2014: Net earnings per share, basic $ 89,559 64,047,803 $ 1.40 Effect of stock options — 260,732 (0.01 ) Net earnings per share, assuming dilution $ 89,559 64,308,535 $ 1.39 For the year ended December 31, 2013: Net earnings per share, basic $ 78,868 63,575,948 $ 1.24 Effect of stock options — 280,816 — Net earnings per share, assuming dilution $ 78,868 63,856,764 $ 1.24 Recently Issued Authoritative Accounting Guidance In 2014, the Financial Accounting Standards Board (the “FASB”) amended its authoritative guidance related to residential real estate to clarify that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, the amendment requires interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. The new guidance was effective for the Company on January 1, 2015 and did not have a significant impact to the Company’s financial statements. In 2014, the FASB issued a comprehensive new revenue recognition standard that will supersede 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. In doing so, companies will need to use more judgment and make more estimates than under existing guidance. These may include identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. The new standard will be effective in the first quarter of 2018. The Company is continuing to evaluate the potential impact to the Company’s financial statements. In 2014, the FASB amended its authoritative guidance related to repurchase-to-maturity transactions to require that repurchase-to-maturity transactions be accounted for as secured borrowings consistent with the accounting for other repurchase agreements. In addition, the amendment requires separate accounting for repurchase financings, which entails the transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty. The amendment requires entities to disclose certain information about transfers accounted for as sales in transactions that are economically similar to repurchase agreements. In addition, the amendment requires disclosures related to collateral, remaining contractual term and of the potential risks associated with repurchase agreements, securities lending transactions and repurchase-to-maturity transactions. The amendment was effective for the Company on January 1, 2015 and did not have a significant impact on the Company’s financial statements. In 2015, the FASB eliminated from U.S. GAAP the concept of extraordinary items, which, among other things, required an entity to show the item separately in the income statement, net of tax, after income from continuing operations. The new guidance is effective for the Company beginning January 1, 2016, though early adoption is permitted, and is not expected to have a significant impact on the Company’s financial statements. In 2015, the FASB amended its business combination guidance to require that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The acquirer must record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the changes to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. Additionally, the entity is required to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. The amended guidance became effective for the Company on January 1, 2016, and is not expected to have a significant impact on the Company’s financial statements. |

Interest-bearing Time Deposits in Banks and Securities | 2. INTEREST-BEARING TIME DEPOSITS IN BANKS AND SECURITIES: Interest-bearing time deposits in banks totaled $3,495,000 and $17,002,000 at December 31, 2015 and 2014, respectively, and have original maturities generally ranging from one to four years. Of these amounts, $489,000 and $3,195,000, respectively, are time deposits with balances greater than $250,000, the FDIC insured limit, at December 31, 2015 and 2014. A summary of the Company’s available-for-sale securities as of December 31, 2015 and 2014 are as follows (in thousands): December 31, 2015 Amortized Gross Gross Estimated Securities available-for-sale: U.S. Treasury securities $ 10,792 $ 5 $ (2 ) $ 10,795 Obligations of U.S. government sponsored enterprises and agencies 148,393 268 (107 ) 148,554 Obligations of state and political subdivisions 1,379,879 71,382 (134 ) 1,451,127 Corporate bonds and other 86,182 1,778 (5 ) 87,955 Residential mortgage-backed securities 781,648 10,993 (3,759 ) 788,882 Commercial mortgage-backed securities 247,991 429 (1,834 ) 246,586 Total securities available-for-sale $ 2,654,885 $ 84,855 $ (5,841 ) $ 2,733,899 December 31, 2014 Amortized Gross Gross Estimated Securities available-for-sale: U.S. Treasury securities $ 518 $ 2 $ — $ 520 Obligations of U.S. government sponsored enterprises and agencies 128,919 864 (28 ) 129,755 Obligations of state and political subdivisions 1,107,795 60,083 (250 ) 1,167,628 Corporate bonds and other 95,864 2,894 — 98,758 Residential mortgage-backed securities 871,265 16,804 (2,858 ) 885,211 Commercial mortgage-backed securities 134,322 555 (893 ) 133,984 Total securities available-for-sale $ 2,338,683 $ 81,202 $ (4,029 ) $ 2,415,856 Disclosures related to the Company’s held-to-maturity securities, which totaled $278,000 and $441,000 at December 31, 2015 and 2014, respectively, have not been presented due to insignificance. 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 December 31, 2015, were computed by using scheduled amortization of balances and historical prepayment rates. At December 31, 2015 and 2014, the Company did not hold any CMOs that entail higher risks than standard mortgage-backed securities. The amortized cost and estimated fair value of available-for-sale securities at December 31, 2015, by contractual and expected maturity, are shown below (in thousands): Amortized Estimated Due within one year $ 138,177 $ 139,086 Due after one year through five years 749,514 783,230 Due after five years through ten years 733,740 771,407 Due after ten years 3,815 4,708 Mortgage-backed securities 1,029,639 1,035,468 Total $ 2,654,885 $ 2,733,899 The following tables disclose, as of December 31, 2015 and 2014, the Company’s investment securities that have been in a continuous unrealized-loss position for less than 12 months and for 12 or more months (in thousands): Less than 12 Months 12 Months or Longer Total December 31, 2015 Fair Unrealized Fair Unrealized Fair Unrealized U.S. Treasury securities $ 5,110 $ 2 $ — $ — $ 5,110 $ 2 Obligations of U.S. government sponsored enterprises and agencies 50,388 107 — — 50,388 107 Obligations of state and political subdivisions 32,929 127 1,513 7 34,442 134 Corporate bonds and other 7,004 5 — — 7,004 5 Residential mortgage-backed securities 231,481 1,765 63,919 1,994 295,400 3,759 Commercial mortgage-backed securities 196,163 1,752 9,345 82 205,508 1,834 Total $ 523,075 $ 3,758 $ 74,777 $ 2,083 $ 597,852 $ 5,841 Less than 12 Months 12 Months or Longer Total December 31, 2014 Fair Unrealized Fair Unrealized Fair Unrealized Obligations of U.S. government sponsored enterprises and agencies $ 25,480 $ 28 $ — $ — $ 25,480 $ 28 Obligations of state and political subdivisions 15,128 60 21,249 190 36,377 250 Residential mortgage-backed securities 76,350 148 128,368 2,710 204,718 2,858 Commercial mortgage-backed securities 48,399 273 55,065 620 103,464 893 Total $ 165,357 $ 509 $ 204,682 $ 3,520 $ 370,039 $ 4,029 The number of investments in an unrealized loss position totaled 94 at December 31, 2015. 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 December 31, 2015 compared to the time of purchase. We have reviewed the ratings of the issuers and have not identified any issues related to the ultimate repayment of principal as a result of credit concerns on these securities. Our mortgage related securities are backed by GNMA, FNMA and FHLMC or are collateralized by securities backed by these agencies. Securities, carried at approximately $1,759,570,000 and $1,600,682,000 at December 31, 2015 and 2014, respectively, were pledged as collateral for public or trust fund deposits, repurchase agreements and for other purposes required or permitted by law. During 2015, 2014, and 2013, sales of investment securities that were classified as available-for-sale totaled $35,580,000, $1,619,000 and $122,025,000. Gross realized gains from 2015, 2014, and 2013, securities sales were $443,000, $2,000 and $1,376,000, respectively. Gross realized losses from 2015, 2014 and 2013 securities sales were $11,000, $6,000 and $1,229,000, respectively. The specific identification method was used to determine cost in order to compute the realized gains and losses. |

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 are charged-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 our on-going monitoring of the credit quality of our loan portfolio. Ratings are adjusted to reflect the degree of risk and loss that are felt to be inherent in each credit as of each reporting period. Our methodology is structured so that specific allocations are increased in accordance with deterioration in credit quality (and a corresponding increase in risk and loss) or decreased in accordance with improvement in credit quality (and a corresponding decrease in risk and loss). Credits rated special mention show clear signs of financial weaknesses or deterioration in credit worthiness, however, such concerns are not so pronounced that the Company generally expects to experience significant loss within the short-term. Such credits typically maintain the ability to perform within standard credit terms and credit exposure is not as prominent as credits rated more harshly. Credits rated substandard are those in which the normal repayment of principal and interest may be, or has been, jeopardized by reason of adverse trends or developments of a financial, managerial, economic or political nature, or important weaknesses exist in collateral. A protracted workout on these credits is a distinct possibility. Prompt corrective action is therefore required to strengthen the Company’s position, and/or to reduce exposure and to assure that adequate remedial measures are taken by the borrower. Credit exposure becomes more likely in such credits and a serious evaluation of the secondary support to the credit is performed. Credits rated doubtful are those in which full collection of principal appears highly questionable, and which some degree of loss is anticipated, even though the ultimate amount of loss may not yet be certain and/or other factors exist which could affect collection of debt. Based upon available information, positive action by the Company is required to avert or minimize loss. Credits rated doubtful are generally also placed on non-accrual.

Fair Value Disclosures [Abstract] | |
Fair Value Disclosures | 8. 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. A description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon internally developed models that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. While management believes the Company’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Securities classified as available-for-sale and trading are reported at fair value utilizing Level 1 and Level 2 inputs. For these securities, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include market spreads, cash flows, the United States Treasury yield curve, live trading levels, trade execution data, dealer quotes, market consensus prepayments speeds, credit information and the security’s terms and conditions, among other items. There were no transfers between Level 2 and Level 3 during the year ended December 31, 2015. The following table summarizes financial assets and financial liabilities measured at fair value on a recurring basis as of December 31, 2015, and 2014 segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value (in thousands): December 31, 2015 Level 1 Level 2 Level 3 Total Fair Available-for-sale investment securities: U.S. Treasury securities $ 10,795 $ — $ — $ 10,795 Obligations of U.

Certain financial assets and financial liabilities are measured at fair value on a nonrecurring basis, that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). Financial assets and financial liabilities measured at fair value on a non-recurring basis include the following at December 31, 2015: Impaired Loans – Impaired loans are reported at the fair value of the underlying collateral if repayment is expected solely from the collateral. Collateral values are estimated using Level 2 inputs based on observable market data. At December 31, 2015, impaired loans with a carrying value of $28,601,000 were reduced by specific valuation reserves totaling $5,071,000 resulting in a net fair value of $23,530,000. Loans Held for Sale – Loans held for sale are reported at the lower of cost or fair value. In determining whether the fair value of loans held for sale is less than cost when quoted market prices are not available, the Company considers investor commitments/contracts. These loans are considered Level 2 of the fair value hierarchy. At December 31, 2015, the Company’s mortgage loans held-for-sale were recorded at cost as fair value approximated cost. Certain non-financial assets and non-financial liabilities measured at fair value on a non-recurring basis include other real estate owned, goodwill and other intangible assets and other non-financial long-lived assets. Non-financial assets measured at fair value on a non-recurring basis during the year ended December 31, 2015 and 2014 include other real estate owned which, subsequent to their initial transfer to other real estate owned from loans, were re-measured at fair value through a write-down included in gain (loss) on sale of foreclosed assets. During the reported periods, all fair value measurements for foreclosed assets utilized Level 2 inputs based on observable market data, generally third-party appraisals, or Level 3 inputs based on customized discounting criteria. These appraisals are evaluated individually and discounted 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. Reevaluation of other real estate owned is performed at least annually as required by regulatory guidelines or more often if particular circumstances arise. The following table presents other real estate owned that were re-measured subsequent to their initial transfer to other real estate owned (dollars in thousands): Year Ended 2015 2014 Carrying value of other real estate owned prior to re-measurement $ 351 $ 881 Write-downs included in gain (loss) on sale of other real estate owned (95 ) (135 ) Fair value $ 256 $ 746 At December 31, 2015 and 2014, other real estate owned totaled $153,000 and $943,000, 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. The carrying value and the estimated fair value of the Company’s contractual off-balance-sheet unfunded lines of credit, loan commitments and letters of credit, which are generally priced at market at the time of funding, are not material. The estimated fair values and carrying values of all financial instruments under current authoritative guidance at December 31, 2015 and 2014, were as follows (dollars in thousands): 2015 2014 Carrying Estimated Carrying Estimated Fair Value Cash and due from banks $ 179,140 $ 179,140 $ 190,387 $ 190,387 Level 1 Federal funds sold 3,810 3,810 8,760 8,760 Level 1 Interest-bearing deposits in banks 89,936 89,936 54,324 54,324 Level 1 Interest-bearing time deposits in banks 3,495 3,500 17,002 17,032 Level 2 Available-for-sale securities 2,733,899 2,733,899 2,415,856 2,415,856 Levels 1 and 2 Held-to-maturity securities 278 283 441 447 Level 2 Loans 3,308,716 3,316,243 2,901,167 2,906,399 Level 3 Accrued interest receivable 34,697 34,697 28,998 28,998 Level 2 Deposits with stated maturities 620,852 622,572 648,992 650,893 Level 2 Deposits with no stated maturities 4,569,317 4,569,317 4,101,263 4,101,263 Level 1 Borrowings 615,675 615,675 367,110 367,110 Level 2 Accrued interest payable 240 240 237 237 Level 2 |

Financial Instruments with Off-Balance-Sheet Risk | 10. FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK: We are a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of our customers. These financial instruments include unfunded lines of credit, commitments to extend credit and federal funds sold 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 the consolidated balance sheets. Our exposure to credit loss in the event of nonperformance by the counterparty to the financial instrument for unfunded lines of credit, commitments to extend credit and standby letters of credit is represented by the contractual notional amount of these instruments. We generally use the same credit policies in making commitments and conditional obligations as we do for on-balance-sheet instruments. Total Notional Financial instruments whose contract amounts represent credit risk: Unfunded lines of credit $ 461,000 Unfunded commitments to extend credit 172,433 Standby letters of credit 31,051 Total commercial commitments $ 664,484 Unfunded lines of credit and commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. These commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. We evaluate each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, as we deem necessary upon extension of credit, is based on our credit evaluation of the counterparty. Collateral held varies but may include accounts receivable, inventory, property, plant, and equipment and income-producing commercial properties. Standby letters of credit are conditional commitments we issue to guarantee the performance of a customer to a third party. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The average collateral value held on letters of credit usually exceeds the contract amount. We believe we have no other off-balance sheet arrangements or transactions with unconsolidated, special purpose entities that would expose us to liability that is not reflected on the face of the financial statements. |

Pension and Profit Sharing Plans | 12. PENSION AND PROFIT SHARING PLANS: The Company’s defined benefit pension plan was frozen effective January 1, 2004, whereby no new participants will be added to the Plan and no additional years of service will accrue to participants, unless the pension plan is reinstated at a future date. The pension plan covered substantially all of the Company’s employees at the time. The benefits for each employee were based on years of service and a percentage of the employee’s qualifying compensation during the final years of employment. The Company’s funding policy was and is to contribute annually the amount necessary to satisfy the Internal Revenue Service’s funding standards. Contributions to the pension plan, prior to freezing the plan, were intended to provide not only for benefits attributed to service to date but also for those expected to be earned in the future. As a result of the Pension Protection Act of 2006 (the “Protection Act”), the Company will be required to contribute amounts in future years to fund any shortfalls. The Company has evaluated the provisions of the Protection Act as well as the Internal Revenue Service’s funding standards to develop a plan for funding in future years. As a result, the Company made a contribution totaling $500,000 and $250,000 in 2015 and 2014, respectively, and is continuing to evaluate future funding amounts. During 2014, as permitted by the Internal Revenue Service, the Company offered settlement of a portion of its pension obligations to those plan participants who no longer were employed by the Company. As a result of the partial settlement of the plan, the Company recognized $2,909,000 in pension expense, before income tax, a component of noninterest expense. The effect of this transaction was relatively neutral to shareholders’ equity since the recorded pension obligation associated with the plan participants who accepted the settlement closely approximated the amount offered to such plan participants and the amount recognized in pension expense had been previously recognized as unrealized losses in other comprehensive earnings. As a result, the Company paid $10,626,000 out of pension plan assets, or approximately 43% of the total outstanding obligation balance, to plan participants and the number of participants was reduced by 335, or 44%. The Company’s investment risk and administrative expense associated with the Company’s pension plan has been significantly reduced going forward. Using an actuarial measurement date of December 31, 2015 and 2014, benefit obligation activity and fair value of plan assets for the years ended December 31, 2015 and 2014, and a statement of the funded status as of December 31, 2015 and 2014, are as follows (dollars in thousands): 2015 2014 Reconciliation of benefit obligations: Benefit obligation at January 1 $ 15,581 $ 25,499 Interest cost on projected benefit obligation 622 1,131 Actuarial loss (gain) 635 1,075 Benefits paid, including partial settlement of certain participant balances (836 ) (12,124 ) Benefit obligation at December 31 $ 16,002 $ 15,581 Reconciliation of fair value of plan assets: Fair value of plan assets at January 1 $ 15,458 $ 25,467 Actual return on plan assets (302 ) 1,865 Employer contributions 500 250 Benefits paid, including partial settlement of certain participant balances (836 ) (12,124 ) Fair value of plan assets at December 31 14,820 15,458 Funded status $ (1,182 ) $ (123 ) Amounts recognized as a component of accumulated other comprehensive earnings as of year-end that have not been recognized as a component of the net period benefit cost of the Company’s defined benefit pension plan are as follows (in thousands): 2015 2014 Net actuarial loss $ (6,098 ) $ (4,435 ) Deferred tax benefit 2,134 1,762 Amounts included in accumulated other comprehensive earnings, net of tax $ (3,964 ) $ (2,673 ) Net periodic benefit cost for the years ended December 31, 2015, 2014, and 2013, are as follows (dollars in thousands): Year Ended December 31, 2015 2014 2013 Service cost - benefits earned during the period $ — $ — $ — Interest cost on projected benefit obligation 622 1,131 1,020 Expected return on plan assets (948 ) (1,497 ) (1,293 ) Amortization of unrecognized net loss 222 337 786 Recognized loss on partial settlement of certain participant balances — 2,909 — Net periodic pension benefit expense (benefit) $ (104 ) $ 2,880 $ 513 The following table sets forth the rates used in the actuarial calculations of the present value of benefit obligations and net periodic pension cost and the rate of return on plan assets: 2015 2014 2013 Weighted average discount rate 4.25 % 4.10 % 4.75 % Expected long-term rate of return on assets 6.25 % 6.25 % 6.25 % The weighted average discount rate is estimated based on setting a discount rate to establish an obligation for pension benefits equivalent to an amount that, if invested in high quality fixed income securities, would produce a return that matches the expected benefit payment stream. The expected long-term rate of return on plan assets is based on historical returns and expectations of future returns based on asset mix, after consultation with our investment advisors and actuaries. The major type of plan assets in the pension plan and the targeted allocation percentage as of December 31, 2015 and 2014 is as follows: December 31, 2015 December 31, 2014 Targeted Equity securities 74 % 75 % 75 % Debt securities 25 % 24 % 25 % Cash and equivalents 1 % 1 % — The range and weighted average final maturities of debt securities held in the pension plan as of December 31, 2015 are 3.52 to 12.34 years and approximately 6.47 years, respectively. Assets held in the pension plan are considered either Level 1 consisting of the money market funds, publicly traded common stocks and publically traded mutual funds or Level 2 consisting of obligations of state and political subdivisions, corporate bonds and mortgage-backed securities. There were no Level 3 securities. See note 8 for a discussion of the fair value hierarchy.

The Company also provides a profit sharing plan, which covers substantially all full-time employees. The profit sharing plan is a defined contribution plan and allows employees to contribute a percentage of their base annual salary. Employees are fully vested to the extent of their contributions and become fully vested in the Company’s contributions over a six-year vesting period. Costs related to the Company’s defined contribution plan totaled approximately $5,455,000, $5,324,000 and $5,686,000 in 2015, 2014 and 2013, respectively, and are included in salaries and employee benefits in the accompanying consolidated statements of earnings. As of December 31, 2015 and 2014, the profit sharing plan’s assets included First Financial Bankshares, Inc. common stock valued at approximately $41,599,000 and $42,008,000, respectively. In 2004, after freezing our pension plan, we added a safe harbor match to the 401(k) plan. We match a maximum of 4% on employee deferrals of 5% of their employee compensation. Total expense for this matching in 2015, 2014 and 2013 was $2,043,000, $1,699,000 and $1,560,000, respectively, and is included in salaries and employee benefits in the statements of earnings. The Company has a directors’ deferred compensation plan whereby the directors may elect to defer up to 100% of their directors’ fees. All deferred compensation is invested in the Company’s common stock held in a rabbi trust. The stock is held in nominee name of the trustee, and the principal and earnings of the trust are held separate and apart from other funds of the Company, and are used exclusively for the uses and purposes of the deferred compensation agreement. The accounts of the trust have been consolidated in the financial statements of the Company. |

Regulatory Matters | 14. REGULATORY MATTERS: The Company is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary, actions by regulators that, if undertaken, could have a direct material effect on the Company’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, each of Bankshares’ subsidiaries must meet specific capital guidelines that involve quantitative measures of the subsidiaries’ assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The subsidiaries’ capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Company and its subsidiaries to maintain minimum amounts and ratios (set forth in the table below) of total and Tier 1 capital (as defined in the regulations) to risk-weighted As of December 31, 2015 and 2014, the most recent notification from our primary regulator categorized the Company and its bank subsidiary as well-capitalized.

As of December 31, 2015, there was $3,941,000 of total unrecognized compensation cost related to nonvested share-based compensation arrangements granted under the Plan. That cost is expected to be recognized over a weighted-average period of 2.58 years. The total fair value of shares vested during the years ended December 31, 2015, 2014, and 2013 was $810,000, $382,000 and $565,000, respectively. The aggregate intrinsic value of vested stock options at December 31, 2015 totaled $4,790,000. On April 28, 2015, shareholders of the Company approved a restricted stock plan for selected employees, officers, non-employee directors and consultants.

Accounting Policies [Abstract] | |
Nature of Operations | Nature of Operations First Financial Bankshares, Inc. (a Texas corporation) (“Bankshares”, “Company”, “we” or “us”) is a financial holding company which owns all of the capital stock of one bank with 70 locations located in Texas as of December 31, 2015. The subsidiary bank is First Financial Bank, National Association, Abilene. The bank’s primary source of revenue is providing loans and banking services to consumers and commercial customers in the market area in which the subsidiary is located. In addition, the Company also owns First Financial Trust & Asset Management Company, National Association, First Financial Insurance Agency, Inc., and First Technology Services, Inc. A summary of significant accounting policies of Bankshares and subsidiaries applied in the preparation of the accompanying consolidated financial statements follows. The accounting principles followed by the Company and the methods of applying them are in conformity with both U.S. generally accepted accounting principles and prevailing practices of the banking industry. The Company evaluated subsequent events for potential recognition through the date the consolidated financial statements were issued. |
Use of Estimates in Preparation of Financial Statements | Use of Estimates in Preparation of Financial Statements The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The Company’s significant estimates include its allowance for loan losses and its valuation of financial instruments. |
Consolidation | Consolidation The accompanying consolidated financial statements include the accounts of Bankshares and its subsidiaries, all of which are wholly-owned. All significant intercompany accounts and transactions have been eliminated. |
Stock Repurchase | Stock Repurchase On October 28, 2014, the Company’s Board of Directors authorized the repurchase of up to 1,500,000 common shares through September 30, 2017. The stock buyback plan authorizes management to repurchase the stock at such time as repurchases are considered beneficial to stockholders. Any repurchase of stock will be made through the open market, block trades or in privately negotiated transactions in accordance with applicable laws and regulations. Under the repurchase plan, there is no minimum number of shares that the Company is required to repurchase. For the years ended December 31, 2015, 2014 and 2013, no shares were repurchased under this or the prior authorization that expired September 30, 2014. |
Stock Split | Stock Split On April 22, 2014, the Company’s Board of Directors declared a two-for-one stock split in the form of a 100% stock dividend effective for shareholders of record on May 15, 2014 that was distributed on June 2, 2014. All share and 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 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 year ended December 31, 2014. |

Investment Securities | Investment Securities Management classifies debt and equity securities as held-to-maturity, available-for-sale, or trading based on its intent. Debt securities that management has the positive intent and ability to hold to maturity are classified as held-to-maturity and recorded at cost, adjusted for amortization of premiums and accretion of discounts, which are recognized as adjustments to interest income using the interest method. Securities not classified as held-to-maturity or trading are classified as available-for-sale and recorded at fair value, with all unrealized gains and unrealized losses judged to be temporary, net of deferred income taxes, excluded from earnings and reported in the consolidated statements of comprehensive earnings. Available-for-sale securities that have unrealized losses that are judged other-than-temporary are included in gain (loss) on sale of securities and a new cost basis is established. Securities classified as trading are recorded at fair value with unrealized gains and losses included in earnings. The Company records its available-for-sale and trading 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 security is below its amortized cost, and depending on the length of time the condition exists and the extent the fair value is below amortized cost, additional analysis is performed to determine whether an other-than-temporary impairment condition exists. Available-for-sale and held-to-maturity securities are analyzed quarterly for possible other-than-temporary impairment. The analysis considers (i) whether we have the intent to sell our securities prior to recovery and/or maturity, (ii) whether it is more likely than not that we will have to sell our securities prior to recovery and/or maturity, (iii) the length of time and extent to which the fair value has been less than 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 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 quarterly, on a sample basis, prices supplied by the independent pricing services by comparison to prices obtained from other third party sources. |
Loans and Allowance for Loan Losses | Loans and Allowance for Loan Losses Loans held for investment are stated at the amount of unpaid principal, reduced by unearned income and an allowance for loan losses. Interest on loans is calculated by using the simple interest method on daily balances of the principal amounts outstanding. The Company defers and amortizes net loan origination fees and costs as an adjustment to yield. The allowance for loan losses is established through a provision for loan losses charged to expense. Loans are charged against the allowance for loan losses when management believes the collectability of the principal is unlikely. The 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 (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 by charge-offs (net of recoveries). Management’s periodic evaluation of the appropriateness of the allowance is based on general economic conditions, the financial condition of borrowers, the value and liquidity of collateral, delinquency, prior loan loss experience, and the results of periodic reviews of the portfolio. For purposes of determining our 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. 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 downturn in the economy and employment could result in increased levels of non-performing assets and charge-offs, increased loan provisions and reductions in income. Additionally, bank regulatory agencies periodically review our allowance for loan losses and methodology and could require, in accordance with generally accepted accounting principles, 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 on non-accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Consumer loans are generally charged-off when a loan becomes past due 90 days. For other loans in the portfolio, facts and circumstances are evaluated in making charge-off decisions. Loans are considered impaired when, based on current information and events, management determines that it is probable we will be unable to collect all amounts due in accordance with the loan agreement, including scheduled principal and interest payments. If a loan is impaired, a specific valuation allowance is allocated, if necessary. Interest payments on impaired loans are typically applied to principal unless collectability of the principal amount is reasonably assured, in which case interest is recognized on a cash basis. Impaired loans, or portions thereof, are charged off when deemed uncollectable. The Company’s policy requires measurement of the allowance for an impaired, collateral dependent loan based on the fair value of the collateral. Other loan impairments for non-collateral dependent loans are measured based on the present value of expected future cash flows or the loan’s observable market price. At December 31, 2015 and 2014, 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. 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 on non-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 December 31, 2015 and 2014, substantially all of the Company’s troubled debt restructured loans are included in the non-accrual totals. The Company originates certain mortgage loans for sale in the secondary market. Accordingly, these loans are classified as held-for-sale and are carried at the lower of cost or fair value on an aggregate basis. The mortgage loan sales contracts contain indemnification clauses should the loans default, generally in the first three to six months, or if documentation is determined not to be in compliance with regulations. The Company’s historic losses as a result of these indemnities have been insignificant. 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 each loan. 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. Contractually required payments for interest and principal that exceed the cash flows expected at acquisition are not recognized as a yield adjustment. Increases in expected cash flows subsequent to the initial investment are recognized prospectively through adjustment of the yield on the loan over its remaining life. 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 December 31, 2015 and 2014 were $2,178,000 and $2,151,000, respectively, compared to a contractual balance of $2,936,000 and $3,275,000, respectively. Other purchased credit impaired loan disclosures were omitted due to immateriality. |
Other Real Estate | Other Real Estate Other real estate owned is foreclosed property held pending disposition and is initially recorded at fair value, less estimated costs to sell. At foreclosure, if the fair value of the real estate, less estimated costs to sell, is less than the Company’s recorded investment in the related loan, a write-down is recognized through a charge to the allowance for loan losses. Any subsequent reduction in value is recognized by a charge to income. Operating and holding expenses of such properties, net of related income, and gains and losses on their disposition are included in net gain (loss) on sale of foreclosed assets as incurred. |
Bank Premises and Equipment | Bank Premises and Equipment Bank premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are computed principally on a straight-line basis over the estimated useful lives of the related assets. Leasehold improvements are amortized over the life of the respective lease or the estimated useful lives of the improvements, whichever is shorter. |
Business Combinations, Goodwill and Other Intangible Assets | Business Combinations, Goodwill and Other Intangible Assets The Company accounts for all business combinations under the purchase method of accounting. Tangible and intangible assets and liabilities of the acquired entity are recorded at fair value. Intangible assets with finite useful lives represent the future benefit associated with the acquisition of the core deposits and are amortized over seven years, utilizing a method that approximates the expected attrition of the deposits. Goodwill with an indefinite life is not amortized, but rather tested annually for impairment as of June 30 each year and totaled $139,971,000 and $94,882,000 at December 31, 2015 and 2014, respectively. There was no impairment recorded for the years ended December 31, 2015, 2014 and 2013. The carrying amount of goodwill arising from acquisitions that qualify as an asset purchase for federal income tax purposes was $74,376,000 and $72,626,000, respectively, at December 31, 2015 and 2014, and is deductible for federal income tax purposes. Also included in other intangible assets are mortgage servicing rights totaling $1,902,000 and $1,834,000 at December 31, 2015 and 2014, respectively. |
Securities Sold Under Agreements To Repurchase | Securities Sold Under Agreements To Repurchase Securities sold under agreements to repurchase, which are classified as borrowings, generally mature within one to four days from the transaction date. Securities sold under agreements to repurchase are reflected at the amount of the cash received in connection with the transaction. The Company may be required to provide additional collateral based on the estimated fair value of the underlying securities. |
Segment Reporting | Segment Reporting The Company has determined that its banking regions meet the aggregation criteria of the current authoritative accounting guidance since each of its banking regions offer similar products and services, operate in a similar manner, have similar customers and report to the same regulatory authority, and therefore operate one line of business (community banking) located in a single geographic area (Texas). |
Statements of Cash Flows | Statements of Cash Flows For purposes of reporting cash flows, cash and cash equivalents includes cash on hand, amounts due from banks, including interest-bearing deposits in banks with original maturity of 90 days or less, and federal funds sold. |
Accumulated Other Comprehensive Income (Loss) | Accumulated Other Comprehensive Income (Loss) Unrealized net gains on the Company’s available-for-sale securities (after applicable income tax expense) totaling $51,359,000 and $50,162,000 at December 31, 2015 and 2014, respectively, and the minimum pension liability totaled (after applicable income tax benefit) totaling $3,964,000 and $2,673,000 at December 31, 2015 and 2014, respectively, are included in accumulated other comprehensive income. |
Income Taxes | Income Taxes The Company’s provision for income taxes is based on income before income taxes adjusted for permanent differences between financial reporting and taxable income. Deferred tax assets and liabilities are determined using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is determined based on the tax effects of the temporary differences between the book and tax bases of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws. |
Stock Based Compensation | Stock Based Compensation The Company grants stock options for a fixed number of shares to employees with an exercise price equal to the fair value of the shares at the grant date. The Company recorded stock option expense totaling $644,000, $709,000 and $411,000 for the years ended December 31, 2015, 2014 and 2013, respectively. The Company also grants restricted stock for a fixed number of shares. The Company recorded expenses associated with its director and officer restricted stock grants totaling $139,000 and $62,000, respectively, for the year ended December 31, 2015. As the restricted stock plans were approved by shareholders in April 2015, there were no such expenses in 2014 and 2013. |
Advertising Costs | Advertising Costs Advertising costs are expensed as incurred. |
Per Share Data | Per Share Data Net earnings per share (“EPS”) are computed by dividing net earnings by the weighted average number of common stock shares outstanding during the period. The Company calculates dilutive EPS assuming all outstanding options to purchase common stock have been exercised at the beginning of the year (or the time of issuance, if later.) The dilutive effect of the outstanding options is reflected by application of the treasury stock method, whereby the proceeds from the exercised options are assumed to be used to purchase common stock at the average market price during the period. The following table reconciles the computation of basic EPS to dilutive EPS: Net Weighted Per Share For the year ended December 31, 2015: Net earnings per share, basic $ 100,381 64,892,934 $ 1.55 Effect of stock options and stock grants — 175,096 (0.01 ) Net earnings per share, assuming dilution $ 100,381 65,068,030 $ 1.54 For the year ended December 31, 2014: Net earnings per share, basic $ 89,559 64,047,803 $ 1.40 Effect of stock options — 260,732 (0.01 ) Net earnings per share, assuming dilution $ 89,559 64,308,535 $ 1.39 For the year ended December 31, 2013: Net earnings per share, basic $ 78,868 63,575,948 $ 1.24 Effect of stock options — 280,816 — Net earnings per share, assuming dilution $ 78,868 63,856,764 $ 1.24 |
Recently Issued Authoritative Accounting Guidance | Recently Issued Authoritative Accounting Guidance In 2014, the Financial Accounting Standards Board (the “FASB”) amended its authoritative guidance related to residential real estate to clarify that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, the amendment requires interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. The new guidance was effective for the Company on January 1, 2015 and did not have a significant impact to the Company’s financial statements. In 2014, the FASB issued a comprehensive new revenue recognition standard that will supersede 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. In doing so, companies will need to use more judgment and make more estimates than under existing guidance. These may include identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. The new standard will be effective in the first quarter of 2018. The Company is continuing to evaluate the potential impact to the Company’s financial statements. In 2014, the FASB amended its authoritative guidance related to repurchase-to-maturity transactions to require that repurchase-to-maturity transactions be accounted for as secured borrowings consistent with the accounting for other repurchase agreements. In addition, the amendment requires separate accounting for repurchase financings, which entails the transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty. The amendment requires entities to disclose certain information about transfers accounted for as sales in transactions that are economically similar to repurchase agreements. In addition, the amendment requires disclosures related to collateral, remaining contractual term and of the potential risks associated with repurchase agreements, securities lending transactions and repurchase-to-maturity transactions. The amendment was effective for the Company on January 1, 2015 and did not have a significant impact on the Company’s financial statements. In 2015, the FASB eliminated from U.S. GAAP the concept of extraordinary items, which, among other things, required an entity to show the item separately in the income statement, net of tax, after income from continuing operations. The new guidance is effective for the Company beginning January 1, 2016, though early adoption is permitted, and is not expected to have a significant impact on the Company’s financial statements. In 2015, the FASB amended its business combination guidance to require that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The acquirer must record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the changes to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. Additionally, the entity is required to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. The amended guidance became effective for the Company on January 1, 2016, and is not expected to have a significant impact on the Company’s financial statements. |
