Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Nature of operations: Independent Bank Group, Inc. (IBG) through its subsidiary, Independent Bank, a Texas state banking corporation (Bank) (collectively known as the Company), provides a full range of banking services to individual and corporate customers in North, Central and Southeast, Texas areas and along the Colorado Front Range, through its various branch locations in those areas. The Company is engaged in traditional community banking activities, which include commercial and retail lending, deposit gathering, investment and liquidity management activities. The Company’s primary deposit products are demand deposits, money market accounts and certificates of deposit, and its primary lending products are commercial business and real estate, real estate mortgage and consumer loans. Basis of presentation: The accompanying consolidated financial statements include the accounts of IBG, its wholly-owned subsidiaries, the Bank, IBG Adriatica Holdings, Inc. (Adriatica) and Carlile Capital, LLC and the Bank’s wholly-owned subsidiaries, IBG Real Estate Holdings, Inc., IBG Real Estate Holdings II, Inc., IBG Aircraft Company III, Preston Grand, Inc., CFRH II, LLC, McKinney Avenue Holdings, Inc. and its wholly owned subsidiary, McKinney Avenue Holdings SPE 1, Inc. Adriatica, CFRH II, LLC, McKinney Avenue Holdings, Inc. and its subsidiary are currently not active entities. On June 1, 2018, the Company acquired Integrity Bancshares, Inc. (Integrity) and its wholly owned subsidiary, Integrity Bank, SSB, Houston, Texas. Integrity has been merged into the Company and dissolved and Integrity Bank has been merged with the Bank as of acquisition date. See Note 21 , Business Combinations for more details of the Integrity acquisition. All material intercompany transactions and balances have been eliminated in consolidation. In addition, the Company wholly-owns IB Trust I (Trust I), IB Trust II (Trust II), IB Trust III (Trust III), IB Centex Trust I (Centex Trust I), Community Group Statutory Trust I (CGI Trust I), Northstar Statutory Trust II (Northstar Trust II) and Northstar Statutory Trust III (Northstar Trust III). The Trusts were formed to issue trust preferred securities and do not meet the criteria for consolidation (see Note 12 ). Accounting standards codification: The Financial Accounting Standards Board's (FASB) Accounting Standards Codification (ASC) is the officially recognized source of authoritative U.S. generally accepted accounting principles (GAAP) applicable to all public and non-public non-governmental entities. Rules and interpretive releases of the SEC under the authority of federal securities laws are also sources of authoritative GAAP for SEC registrants. All other accounting literature is considered non-authoritative. Citing particular content in the ASC involves specifying the unique numeric path to the content through the Topic, Subtopic, Section and Paragraph structure. Segment reporting: The Company has one reportable segment. The Company’s chief operating decision-maker uses consolidated results to make operating and strategic decisions. Reclassifications: Certain prior period financial statement amounts have been reclassified to conform to current period presentation. The reclassifications have no effect on net income or stockholders' equity as previously reported. Use of estimates: The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect certain reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Accordingly, actual results could differ from those estimates. The material estimates included in the financial statements relate to the allowance for loan losses, the valuation of goodwill and valuation of assets and liabilities acquired in business combinations. Cash and cash equivalents: For the purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from banks and federal funds sold. All highly liquid investments with an initial maturity of less than ninety days are considered to be cash equivalents. The Company maintains deposits with other financial institutions in amounts that exceed FDIC insurance coverage. The Company's management monitors the balance in these accounts and periodically assesses the financial condition of the other financial institutions. The Company has not experienced any losses in such accounts and believes it is not exposed to any significant credit risks on cash or cash equivalents. Certificates of deposit: Certificates of deposit are FDIC insured deposits in other financial institutions that mature within 18 months and are carried at cost. Securities: Securities classified as available for sale are those debt securities that the Company intends to hold for an indefinite period of time, but not necessarily to maturity. Any decision to sell a security classified as available for sale would be based on various factors, including significant movements in interest rates, changes in the maturity mix of the Company's assets and liabilities, liquidity needs, regulatory capital considerations and other similar factors. Securities available for sale are reported at fair value with unrealized gains or losses reported as a separate component of other comprehensive income, net of tax. The amortization of premiums and accretion of discounts, computed by the interest method over their contractual lives, are recognized in interest income. Realized gains or losses, determined on the basis of the cost of specific securities sold, are included in earnings on the trade date. In estimating other than temporary impairment losses, management considers (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) the intent of the Company to retain its investment and whether it is more likely than not the Company will be required to sell its investment before its anticipated recovery in fair value. When the Company does not intend to sell the security, and it is more likely than not that it will not have to sell the security before recovery of its cost basis, it will recognize the credit component of an other than temporary impairment of a debt security in earnings and the remaining portion in other comprehensive income. Loans held for sale: The Company originates residential mortgage loans that may subsequently be sold to unaffiliated third parties. The Company elected the fair value option for certain residential mortgage loans held for sale originated after July 1, 2018 in accordance with ASC 825, Financial Instruments. This election allows for a more effective offset of the changes in fair values of the loans and the derivative instruments used to economically hedge them without the burden of complying with the requirements for hedge accounting under ASC 815, Derivatives and Hedging . The Company has not elected the fair value option for other residential mortgage loans held for sale primarily because they are not economically hedged using derivative instruments. Mortgage loans originated and intended for sale not recorded under the fair value option are carried at the lower of aggregate cost or fair value, as determined by aggregate outstanding commitments from investors. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income. All mortgage loans held for sale are sold without servicing rights retained. Gains and losses on sales of loans are recognized in noninterest income at settlement dates and are determined by the difference between the sales proceeds and the carrying value of the loans. Acquired loans: Acquired loans from the transactions accounted for as a business combination include both non-performing loans with evidence of credit deterioration since their origination date and performing loans. The Company is accounting for the non-performing loans acquired in accordance with ASC 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality . The performing loans are being accounted for under ASC 310-20, Nonrefundable Fees and Other Costs , with the related difference in the initial fair value and unpaid principal balance (the discount) recognized as interest income on a level yield basis over the life of the loan. At the date of the acquisition, the acquired loans are recorded at their fair value with no valuation allowance. Purchased credit impaired loans are accounted for individually. The Company estimates the amount and timing of undiscounted expected cash flows for each loan, and the expected cash flows in excess of fair value is recorded as interest income over the remaining life of the loan (accretable yield). The excess of the loan's contractual principal and interest over expected cash flows is not recorded (nonaccretable difference). Over the life of the loan, expected cash flows continue to be estimated. If the expected cash flows decrease, an impairment loss is recorded. If the expected cash flows increase, it is recognized as part of future interest income. Loans, net: Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are reported at their outstanding principal balance, net of unearned interest, purchase premiums and discounts, deferred loan fees and an allowance for loan losses. Fees and costs associated with originating loans are generally recognized in the period they are incurred, except in the Houston market, former Grand Bank and Carlile branches, which fees are deferred. The provisions of ASC 310, Receivables , generally provide that such fees and related costs be deferred and recognized over the life of the loan as an adjustment of yield. Management believes that not deferring such amounts and amortizing them over the life of the related loans does not materially affect the financial position or results of operations of the Company. Allowance for loan losses: The allowance for loan losses is maintained at a level considered adequate by management to provide for probable loan losses. The allowance is increased by provisions charged to expense. Loans are charged against the allowance for loan losses when management believes that collectability of the principal is unlikely. Subsequent recoveries, if any, are credited to the allowance. The provision for loan losses is the amount, which, in the judgment of management, is necessary to establish the allowance for loan losses at a level that is adequate to absorb known and inherent risks in the loan portfolio. See Note 6 for further information on the Company's policies and methodology used to estimate the allowance for loan losses. Premises and equipment, net: Land is carried at cost. Bank premises, furniture and equipment and aircraft are carried at cost, less accumulated depreciation computed principally by the straight-line method over the estimated useful lives of the assets, which range from three to thirty years. Leasehold improvements are carried at cost and are depreciated over the shorter of the estimated useful life or the lease period. Long-term assets: Premises and equipment and other long-term assets are reviewed for impairment when events indicate that their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value. Other real estate owned: Real estate properties acquired through, or in lieu of, loan foreclosure are initially recorded at fair value less estimated selling costs at the date of foreclosure, establishing a new cost basis. After foreclosure, valuations are periodically performed by management and the real estate is carried at the lower of carrying amount or fair value less cost to sell. Revenue and expenses from operations of other real estate owned and impairment charges on other real estate are included in noninterest expense. Gains and losses on sale of other real estate are included in noninterest income. Goodwill and core deposit intangible, net: Goodwill represents the excess of costs over fair value of net assets of businesses acquired. Goodwill is tested for impairment annually on December 31 or on an interim basis if an event triggering impairment may have occurred. Core deposit intangibles are acquired customer relationships arising from bank acquisitions and are amortized on a straight-line basis over their estimated useful lives of ten years. Core deposit intangibles are tested for impairment whenever events or changes in circumstances indicate the carrying amount of the assets may not be recoverable from future undiscounted cash flows. Restricted stock : The Bank is a member of the FHLB system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB of Dallas and Independent Bankers Financial Corporation stock do not have readily determinable fair values as ownership is restricted and they lack a ready market. As a result, these stocks are carried at cost and evaluated periodically by management for impairment. Both cash and stock dividends are reported as income. Bank-owned life insurance: Bank-owned life insurance is recorded at the amount that can be realized under the insurance contracts at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement. Changes in the net cash surrender value of the policies, as well as insurance proceeds received are reflected in noninterest income. Income taxes: Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities (excluding deferred tax assets and liabilities related to business combinations or components of other comprehensive income). Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. The effect of a change in tax rates on deferred assets and liabilities is recognized in income taxes during the period that includes the enactment date. A valuation allowance, if needed, reduces deferred tax assets to the expected amount more likely than not to be realized. Realization of deferred tax assets is dependent upon the level of historical income, prudent and feasible tax planning strategies, reversals of deferred tax liabilities and estimates of future taxable income. The Company evaluates uncertain tax positions at the end of each reporting period. The Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefit recognized in the financial statements from any such position is measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. For tax positions not meeting the "more likely than not" test, no tax benefit is recorded. Any interest and/or penalties related to income taxes are reported as a component of income tax expense. Loan commitments and related financial instruments: In the ordinary course of business, the Company has entered into certain off-balance-sheet financial instruments consisting of commitments to extend credit, commercial letters of credit, and standby letters of credit. Such financial instruments are recorded in the financial statements when they are funded or related fees are incurred or received. Management estimates losses on off-balance-sheet financial instruments using the same methodology as for portfolio loans. Estimated losses on off-balance-sheet financial instruments are recorded by charges to the provision for losses and credits to other liabilities in the Company's consolidated balance sheet. There were no estimated losses on off-balance sheet financial instruments as of December 31, 2018 or 2017 . Stock based compensation: Compensation cost is recognized for restricted stock awards issued to employees based on the market price of the Company's common stock on the grant date. Stock-based compensation expense is generally recognized using the straight-line method over the requisite service period for all awards. The impact of forfeitures of stock-based payment awards on compensation expense is recognized as forfeitures occur. Transfers of financial assets: Transfers of financial assets are accounted for as sales, when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Company, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Advertising costs: Advertising costs are expensed as incurred. Business combinations: The Company applies the acquisition method of accounting for business combinations. Under the acquisition method, the acquiring entity in a business combination recognizes 100% of the assets acquired and liabilities assumed at their acquisition date fair values. Management utilizes valuation techniques appropriate for the asset or liability being measured in determining these fair values. Any excess of the purchase price over amounts allocated to assets acquired, including identifiable intangible assets, and liabilities assumed is recorded as goodwill. Where amounts allocated to assets acquired and liabilities assumed is greater than the purchase price, a bargain purchase gain is recognized. Adjustments identified during the measurement period are recognized in the reporting period in which the adjustment amounts are determined. Acquisition-related costs are expensed as incurred. Comprehensive income: Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities, such as unrealized gains and losses on available for sale securities, are reported as a separate component of the equity section of the balance sheet, such items, along with net income, are components of comprehensive income. Gains and losses on available for sale securities are reclassified to net income as the gains or losses are realized upon sale of the securities. The credit component of other than temporary impairment charges are reclassified to net income at the time of the charge. Fair values of financial instruments: Accounting standards define fair value, establish a framework for measuring fair value in U.S. generally accepted accounting principles, and require certain disclosures about fair value measurements (see Note 17 , Fair Value Measurements). In general, fair values of financial instruments are based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon 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. These adjustments may include amounts to reflect counterparty credit quality and the Company's creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. Derivative financial instruments: The Company enters into certain derivative financial instruments: interest rate lock commitments, forward mortgage-backed securities trades and interest rate swaps. These financial instruments are not designated as hedging instruments and are used for asset and liability management related to the Company's mortgage banking activities and commercial customers' financing needs. All derivatives are carried at fair value in either other assets or other liabilities (see Note 18 , Derivative Financial Instruments ) . Mortgage banking: This revenue category reflects the Company's mortgage production revenue, including fees and income derived from mortgages originated with the intent to sell, gains on sales of mortgage loans and t he initial and subsequent changes in the fair value of the mortgage derivatives . Interest earned on mortgage loans is recorded in interest income. Revenue recognition: The Company adopted Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (Topic 606) as of January 1, 2018 (See Note 2 , Recent Accounting Pronouncements). ASC Topic 606, R evenue from Contracts with Customers , establishes principles for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from the entity's contracts to provide goods or services to customers. The core principle requires an entity to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration that it expects to be entitled to receive in exchange for those goods or services recognized as performance obligations are satisfied. The majority of the Company's revenue-generating transactions are not subject to ASC 606, including revenue generated from financial instruments, such as loans, letters of credit, and investment securities, as well as revenue related to mortgage banking activities, and BOLI, as these activities are subject to other accounting guidance. Descriptions of revenue-generating activities that are within the scope of ASC 606, and are presented in the accompanying Consolidated Statements of Income as components of noninterest income, are as follows: • Service charges on deposit accounts - these represent general service fees for monthly account maintenance and activity- or-transaction-based fees and consist of transaction-based revenue, time-based revenue (service period), item-based revenue or some other individual attribute-based revenue. Revenue is recognized when the performance obligation is completed which is generally monthly for account maintenance services or when a transaction has been completed (such as a wire transfer). Payment for such performance obligations are generally received at the time the performance obligations are satisfied. • Gains/losses on the sale of other real estate owned - generally recognized when the performance obligation is complete which is typically at delivery of control over the property to the buyer at time of each real estate closing. • Other noninterest income - includes the Company's correspondent bank earnings credit, mortgage warehouse purchase program fees, acquired loan recoveries, wealth management referral income, other deposit fees, and merchant interchange income. The majority of these fees in other noninterest income are not subject to the requirements of ASC 606. The wealth management referral fees, other deposit fees and merchant interchange income are in the scope of ASC 606, and payment for such performance obligations are generally received at the time the performance obligations are satisfied. The Company has made no significant judgments in applying the revenue guidance prescribed in ASC 606 that affect the determination of the amount and timing of revenue from the above-described contracts with customers. Share repurchase program: The Company established share repurchase programs in prior years which would allow the Company to purchase its common stock in the open market or in privately negotiated transactions. In general, share repurchase programs allow the Company to proactively manage its capital position and return excess capital to shareholders. On October 24, 2018, the Company announced the reestablishment of its share repurchase program. The program authorizes the purchase by the Company of up to $75,000 of its common stock. The repurchase program is authorized to continue through October 1, 2019. No shares of Company stock were repurchased by the Company under this program during 2018. Subsequent events: Companies are required to evaluate events and transactions that occur after the balance sheet date but before the date the financial statements are issued. They must recognize in the financial statements the effect of all events or transactions that provide additional evidence of conditions that existed at the balance sheet date, including the estimates inherent in the financial statement preparation process. Entities shall not recognize the impact of events or transactions that provide evidence about conditions that did not exist at the balance sheet date but arose after that date. The Company has evaluated subsequent events through the date of filing these financial statements with the SEC and noted no subsequent events requiring financial statement recognition or disclosure, except as disclosed in Note 24 . Earnings per share: Basic earnings per common share are net income divided by the weighted average number of common shares outstanding during the period. The unvested share-based payment awards that contain rights to non forfeitable dividends are considered participating securities for this calculation. Diluted earnings per common share include the dilutive effect of additional potential common shares issuable under stock warrants. The participating nonvested common stock was not included in dilutive shares as it was anti-dilutive for the years ended December 31, 2018 and 2017 . Proceeds from the assumed exercise of dilutive stock warrants are assumed to be used to repurchase common stock at the average market price. No stock warrants remain outstanding as of December 31, 2018. The following table presents a reconciliation of net income available to common shareholders and the number of shares used in the calculation of basic and diluted earnings per common share. Years ended December 31, 2018 2017 2016 Basic earnings per share: Net income $ 128,259 $ 76,512 $ 53,540 Less: Preferred stock dividends — — 8 Net income after preferred stock dividends 128,259 76,512 53,532 Less: Undistributed earnings allocated to participating securities 976 626 774 Dividends paid on participating securities 139 97 103 Net income available to common shareholders $ 127,144 $ 75,789 $ 52,655 Weighted-average basic shares outstanding 29,341,843 25,394,079 18,198,578 Basic earnings per share $ 4.33 $ 2.98 $ 2.89 Diluted earnings per share: Net income available to common shareholders $ 127,144 $ 75,789 $ 52,655 Weighted-average basic shares outstanding 29,341,843 25,394,079 18,198,578 Add dilutive stock warrants — 106,070 86,646 Total weighted-average diluted shares outstanding 29,341,843 25,500,149 18,285,224 Diluted earnings per share $ 4.33 $ 2.97 $ 2.88 Anti-dilutive participating securities 114,087 123,564 92,196 |

Recent Accounting Pronouncements | Recent Accounting Pronouncements Adoption of new accounting standards ASU 2014-09, Revenue from Contracts with Customers (Topic 606), ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date. ASU 2014-09 amends existing guidance related to revenue from contracts with customers. The amendments state that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 affects entities that enter into contracts with customers to transfer goods or services or enter into contracts for the transfer of nonfinancial assets, unless those contracts are within the scope of other standards. The Company's revenue consists of net interest income on financial assets and financial liabilities, which is explicitly excluded from the scope of ASU 2014-9, and non-interest income. The Company adopted ASU 2014-09 in the first quarter of 2018 using the modified retrospective approach effective on January 1, 2018 to all existing contracts with customers covered under the scope of the standard. The Company did not have an aggregate effect of modification resulting from the adoption of ASU 2014-09, and no financial statement line items were affected by this change in accounting standard. The newly applicable revenue disclosures have been included in the footnotes to these financial statements (see Note 1, Summary of Significant Accounting Policies). ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. This ASU required that all equity investments be measured at fair value with changes in the fair value recognized through net income (other than those accounted for under the equity method of accounting or those that result in consolidation of the investee). This ASU also required that an entity 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. Additionally, this ASU required that public business entities base their fair value disclosures for financial instruments that are not measured at fair value in the financial statements on the exit price notion. The Company adopted ASU 2016-01 in the first quarter of 2018, and have estimated fair values of loans held for investment for the 2018 period on cash flows, adjusted for credit and prepayments, discounted using current market yields (see Note 17, Fair Value Measurements). The adoption of this ASU did not have a material impact on the Company’s financial statements. ASU 2016-15, Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash Payments. This ASU was intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows, including debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims and distributions received from equity method investments. ASU 2016-15 became effective for the Company on January 1, 2018 and did not have a significant impact on its financial statements. ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220) - Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The amendments in this update allow reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act (TCJA) which was signed into law on December 22, 2017. The Company elected to early adopt ASU 2018-02 in the first quarter of 2018 and apply the guidance to the beginning of the period, effective January 1, 2018 . The impact of adopting the amendment resulted in a cumulative effect adjustment to the consolidated balance sheet as of January 1, 2018 to reclassify approximately $233 of tax expense from accumulated other comprehensive loss to retained earnings as reflected in the accompanying Consolidated Statements of Changes in Stockholders' Equity. Newly issued but not yet effective accounting standards ASU 2016-02, Leases (Topic 842). This ASU will, among other things, require lessees to recognize a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-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. Under this guidance, lessor accounting is largely unchanged. This ASU is effective for annual and interim periods for the Company on January 1, 2019. The Company will adopt the standard by applying the alternative transition method whereby comparative periods will not be restated, and any cumulative effect adjustment to the opening balance of retained earnings would be recognized as of January 1, 2019. The impact to retained earnings is expected to be immaterial. The Company also expects to elect the ASU’s package of three practical expedients, which allows the Company to forego a reassessment of (i) whether any expired or existing contracts are or contain leases, (ii) the lease classification for any expired or existing leases and (iii) the initial direct costs for any existing leases. The Company also does not expect to apply the recognition requirements of the ASU to any short-term leases (as defined by related accounting guidance) and expects to account for lease and non-lease components separately because such amounts are readily determinable under most lease contracts and because we expect this election will result in a lower impact on our balance sheet. The Company has implemented a lease management system to assist in centralizing, maintaining and accounting for all leases and is finalizing its evaluation of the ASU on its financial statements and disclosures, as well as any additional changes to processes and internal controls to ensure we meet the ASU’s reporting and disclosure requirements. The Company currently expects to recognize right-of-use assets and related lease liabilities totaling approximately $26,800 and $21,900 , respectively. The adoption of this ASU is not expected to have a significant impact on the Company’s consolidated statement of income. Presentation of leases within the consolidated statements of income and consolidated statements of cash flows will be generally consistent with the current lease accounting guidance. ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This ASU removes the thresholds that companies apply to measure credit losses on financial instruments measured at amortized cost, such as loans, receivables and held-to-maturity debt securities. Under current US GAAP, companies generally recognize credit losses when it is probable that the loss has been incurred. This revised guidance will remove all recognition thresholds and will require companies to recognize an allowance for lifetime expected credit losses. Credit losses will be immediately recognized through net income; the amount recognized will be based on the current estimate of contractual cash flows not expected to be collected over the financial asset’s contractual term. ASU 2016-13 also amends the credit loss measurement guidance for available for sale debt securities. This ASU will be effective for the Company on January 1, 2020. The Company is currently evaluating the potential impact of ASU 2016-13 on its financial statements and has formed a cross-functional working group, under the direction of executive management including the Chief Financial Officer and Chief Risk Officer. The working group is comprised of individuals from various functional areas including credit, risk management, accounting and information technology, among others. The Company is currently working through its implementation plan which includes such things as assessment and documentation of processes, internal controls and data sources; model development and documentation; and system configuration. The Company is also in the process of implementing a third-party vendor solution to assist in the application of the ASU 2016-13. The adoption of ASU 2016-13 could result in an increase in the allowance for loan losses as a result of changing from an “incurred loss” model, which encompasses allowances for current known and inherent losses within the portfolio, to an “expected loss” model, which encompasses allowances for losses expected to be incurred over the life of the portfolio. Furthermore, this ASU will necessitate that the Company establish an allowance for expected credit losses for certain debt securities and other financial assets. While the Company is currently unable to reasonably estimate the impact of adopting ASU 2016-13, the Company expects that the impact of adoption will be significantly influenced by the composition, characteristics and quality of our loan and securities portfolios as well as the prevailing economic conditions and forecasts as of the adoption date. ASU 2017-04, Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment. This ASU simplifies the accounting for goodwill impairment for all entities by requiring impairment charges to be based on the first step in today’s two-step impairment test. Under the new guidance, if a reporting unit’s carrying amount exceeds its fair value, an entity will record an impairment charge based on that difference. The impairment charge will be limited to the amount of goodwill allocated to that reporting unit. The standard eliminates today’s requirement to calculate a goodwill impairment charge using Step 2, which requires an entity to calculate any impairment charge by comparing the implied fair value of goodwill with its carrying amount. ASU 2017-04 will be effective for the Company on January 1, 2020, with earlier adoption permitted and is not expected to have a significant impact on its financial statements. ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities . This ASU requires certain premiums on callable debt securities to be amortized to the earliest call date. The amortization period for callable debt securities purchased at a discount will not be impacted. Under current GAAP, premiums on callable debt securities are generally amortized over the contractual life of the security. ASU 2017-08 will be effective for the Company on January 1, 2019 and, upon adoption, the Company expects to recognize a cumulative effect adjustment reducing retained earnings by approximately $880 , but otherwise is not expected to have a significant impact to the Company's consolidated financial statements and disclosures. ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. This ASU refines and expand hedge accounting for both financial and commodity risks. Its provisions create more transparency around how economic results are presented, both on the face of the financial statements and in the footnotes. It also makes certain targeted improvements to simplify the application of hedge accounting guidance. ASU 2017-02 will be effective for the Company on January 1, 2019. The adoption of this ASC is not expected to have a significant impact on the Company's consolidated financial statements and disclosures. ASU 2018-07, Improvements to Nonemployee Share-Based Payment Accounting . This ASU aligns much of the guidance on measuring and classifying nonemployee awards with that of awards to employees. The guidance applies to nonemployee awards issued in exchange for goods or services used or consumed in an entity’s own operations and to awards granted by an investor to employees and nonemployees of an equity method investee for goods or services used or consumed in the investee’s operations. There are no new disclosure requirements. This ASU will be effective for the Company on January 1, 2019. The adoption of this ASU is not expected to have a significant impact on the Company’s financial statements and disclosures. ASU 2018-13, Fair Value Measurement (Topic 820) - Changes to the Disclosure Requirements for Fair Value Measurement . This ASU modifies the disclosure requirements on fair value measurements by requiring that Level 3 fair value disclosures include the range and weighted average of significant unobservable inputs used to develop those fair value measurements. For certain unobservable inputs, an entity may disclose other quantitative information in lieu of the weighted average if the entity determines that other quantitative information would be a more reasonable and rational method to reflect the distribution of unobservable inputs used to develop Level 3 fair value measurements. ASU 2018-13 will be effective for the Company on January 1, 2020, with early adoption permitted, and is not expected to have a significant impact on its financial statements and disclosures. ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) - Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. This ASU aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). The accounting for the service element of a hosting arrangement that is a service contract is not affected by these amendments. This ASU will be effective for the Company on January 1, 2020, with early adoption permitted, and is not expected to have a significant impact on its financial statements and disclosures. |

Loans, Net and Allowance for Loan Losses | Loans, Net and Allowance for Loan Losses Loans, net at December 31, 2018 and 2017 , consisted of the following: December 31, 2018 2017 Commercial $ 1,361,104 $ 1,059,984 Real estate: Commercial 4,141,356 3,369,892 Commercial construction, land and land development 905,421 744,868 Residential 1,049,521 892,293 Single family interim construction 331,748 289,680 Agricultural 66,638 82,583 Consumer 31,759 34,639 Other 253 304 7,887,800 6,474,243 Deferred loan fees (3,303 ) (2,568 ) Allowance for loan losses (44,802 ) (39,402 ) $ 7,839,695 $ 6,432,273 The Company has certain lending policies and procedures in place that are designed to maximize loan income within an acceptable level of risk. Management reviews and approves these policies and procedures on a regular basis. A reporting system supplements the review process by providing management with frequent reports related to loan production, loan quality, concentrations of credit, loan delinquencies and non-performing and potential problem loans. Commercial loans are underwritten after evaluating and understanding the borrower’s ability to operate profitably and prudently expand its business. The Company’s management examines 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. These cash flows, however, may not be as expected and the value of collateral securing the loans may fluctuate. Most commercial loans are secured by the assets being financed or other business assets such as accounts receivable or inventory and may incorporate a personal guarantee; however, some short term loans may be made on an unsecured basis. Additionally, our commercial loan portfolio includes loans made to customers in the energy industry, which is a complex, technical and cyclical industry. Experienced bankers with specialized energy lending experience originate our energy loans. Companies in this industry produce, extract, develop, exploit and explore for oil and natural gas. Loans are primarily collateralized with proven producing oil and gas reserves based on a technical evaluation of these reserves. At December 31, 2018 and 2017 , there were approximately $135,034 and $106,060 , respectively, of energy related loans outstanding. The Company has a mortgage warehouse purchase program which provides a mortgage warehouse lending vehicle to third party mortgage bankers across a broad geographic scale. The mortgage loans are underwritten, in part, on approved investor takeout commitments. These loans have a very short duration ranging between 10 days and 15 days . In some cases, loans to larger mortgage originators may be financed for up to 60 days . These loans are reported as commercial loans since the loans are secured by notes receivable, not real estate. As of December 31, 2018 and 2017 , mortgage warehouse purchase loans outstanding totaled $170,290 and $164,694 , respectively. Commercial real estate loans are subject to underwriting standards and processes similar to commercial loans. These loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Commercial real estate lending typically involves higher loan principal amounts and the repayment of these loans is generally largely dependent on the successful operation of the property or the business conducted on the property securing the loan. Commercial 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 commercial real estate portfolio are diverse in terms of type and geographic location. Management monitors the diversification of the portfolio on a quarterly basis by type and geographic location. Management also tracks the level of owner occupied property versus non owner occupied property. At December 31, 2018 , the portfolio consisted of approximately 33% of owner occupied property. Land and commercial land development loans are underwritten using feasibility studies, independent appraisal reviews and financial analysis of the developers or property owners. Generally, borrowers must have a proven track record of success. Commercial construction loans are generally based upon estimates of cost and value of the completed project. These estimates may not be accurate. Commercial construction loans often involve the disbursement of substantial funds with the repayment dependent on the success of the ultimate project. Sources of repayment for these loans may be pre-committed permanent financing or sale of the developed property. The loans in this portfolio are geographically diverse and due to the increased risk are monitored closely by management and the board of directors on a quarterly basis. Residential real estate and single family interim construction loans are underwritten primarily based on borrowers’ credit scores, documented income and minimum collateral values. Relatively small loan amounts are spread across many individual borrowers which minimizes risk in the residential portfolio. In addition, management evaluates trends in past dues and current economic factors on a regular basis. Agricultural loans are collateralized by real estate and/or agricultural-related assets. Agricultural real estate loans are primarily comprised of loans for the purchase of farmland. Loan-to-value ratios on loans secured by farmland generally do not exceed 80% and have amortization periods limited to twenty years. Agricultural non-real estate loans are generally comprised of term loans to fund the purchase of equipment, livestock and seasonal operating lines to cash grain farmers to plant and harvest corn and soybeans. Specific underwriting standards have been established for agricultural-related loans including the establishment of projections for each operating year based on industry developed estimates of farm input costs and expected commodity yields and prices. Operating lines are typically written for one year and secured by the crop and other farm assets as considered necessary. Agricultural loans carry significant credit risks as they involve larger balances concentrated with single borrowers or groups of related borrowers. In addition, repayment of such loans depends on the successful operation or management of the farm property securing the loan or for which an operating loan is utilized. Farming operations may be affected by adverse weather conditions such as drought, hail or floods that can severely limit crop yields. Consumer loans represent less than 1% of the outstanding total loan portfolio. Collateral consists primarily of automobiles and other personal assets. Credit score analysis is used to supplement the underwriting process. Most of the Company’s lending activity occurs within the State of Texas, primarily in the north, central and southeast Texas regions and the State of Colorado, specifically along the Front Range area. As of December 31, 2018 , loans in the Colorado region represented about 6% of the total portfolio. A large percentage of the Company’s portfolio consists of commercial and residential real estate loans. As of December 31, 2018 and 2017 , there were no concentrations of loans related to a single industry in excess of 10% of total loans. The allowance for loan losses is an amount that management believes will be adequate to absorb estimated losses relating to specifically identified loans, as well as probable credit losses inherent in the balance of the loan portfolio. The allowance is derived from the following two components: 1) allowances established on individual impaired loans, which are based on a review of the individual characteristics of each loan, including the customer’s ability to repay the loan, the underlying collateral values and the industry the customer operates and 2) allowances based on actual historical loss experience for the last three years for similar types of loans in the Company’s loan portfolio adjusted for primarily changes in the lending policies and procedures; collection, charge-off and recovery practices; nature and volume of the loan portfolio; change in value of underlying collateral; volume and severity of nonperforming loans; existence and effect of any concentrations of credit and the level of such concentrations and current, national and local economic and business conditions. This second component also includes an unallocated allowance to cover uncertainties that could affect management’s estimate of probable losses. The unallocated allowance reflects the imprecision inherent in the underlying assumptions used in the methodologies for estimating this component. The Company’s management continually evaluates the allowance for loan losses determined from the allowances established on individual loans and the amounts determined from historical loss percentages adjusted for the qualitative factors above. Should any of the factors considered by management change, the Company’s estimate of loan losses could also change and would affect the level of future provision expense. While the calculation of the allowance for loan losses utilizes management’s best judgment and all the information available, the adequacy of the allowance for loan losses is dependent on a variety of factors beyond the Company’s control, including, among other things, the performance of the entire loan portfolio, the economy, changes in interest rates and the view of regulatory authorities towards loan classifications. In addition, regulatory agencies, as an integral part of their examination process, periodically review the Bank’s allowance for loan losses, and may require the Bank to make additions to the allowance based on their judgment about information available to them at the time of their examinations. Loans requiring an allocated loan loss provision are generally identified at the servicing officer level based on review of weekly past due reports and/or the loan officer’s communication with borrowers. In addition, past due loans are discussed at weekly officer loan committee meetings to determine if classification is warranted. The Company’s credit department has implemented an internal risk based loan review process to identity potential internally classified loans that supplements the annual independent external loan review. The external review generally covers all loans greater than $4,125 annually. These reviews include analysis of borrower’s financial condition, payment histories and collateral values to determine if a loan should be internally classified. Generally, once classified, an impaired loan analysis is completed by the credit department to determine if the loan is impaired and the amount of allocated allowance required. The Texas and Colorado economies, specifically the Company’s lending area of north, central and southeast Texas and the Colorado Front Range area, continued to be strong throughout 2018. The Texas economy, which is the second largest in the nation, and the Colorado economy are out-pacing the U.S. economy in job creation and employment growth. Overall, the forecast is positive with continued moderate growth in the manufacturing and service sectors and rising activity in the energy sector. While the current economic outlook remains optimistic, future and long-term concerns continue to include the tightening labor markets, decreased housing affordability, energy price volatility and trade uncertainty. The risk of loss associated with all segments of the portfolio could increase due to these factors. The economy and other risk factors are minimized by the Company’s underwriting standards which include the following principles: 1) financial strength of the borrower including strong earnings, high net worth, significant liquidity and acceptable debt to worth ratio, 2) managerial business competence, 3) ability to repay, 4) loan to value, 5) projected cash flow and 6) guarantor financial statements as applicable. The following is a summary of the activity in the allowance for loan losses by loan class for the years ended December 31, 2018 , 2017 and 2016 : Commercial Commercial Real Estate, Construction, Land and Land Development Residential Real Estate Single-Family Interim Construction Agricultural Consumer Other Unallocated Total Year ended December 31, 2018 Balance at the beginning of year $ 10,599 $ 23,301 $ 3,447 $ 1,583 $ 250 $ 205 $ (32 ) $ 49 $ 39,402 Provision for loan losses 4,973 4,909 (124 ) (181 ) (9 ) 69 210 13 9,860 Charge-offs (3,863 ) (435 ) (6 ) — — (93 ) (228 ) — (4,625 ) Recoveries 84 20 3 — — 5 53 — 165 Balance at the end of year $ 11,793 $ 27,795 $ 3,320 $ 1,402 $ 241 $ 186 $ 3 $ 62 $ 44,802 Year ended December 31, 2017 Balance at the beginning of year $ 8,593 $ 18,399 $ 2,760 $ 1,301 $ 207 $ 242 $ 29 $ 60 $ 31,591 Provision for loan losses 2,059 4,886 683 416 43 99 90 (11 ) 8,265 Charge-offs (81 ) (15 ) — (134 ) — (182 ) (190 ) — (602 ) Recoveries 28 31 4 — — 46 39 — 148 Balance at the end of year $ 10,599 $ 23,301 $ 3,447 $ 1,583 $ 250 $ 205 $ (32 ) $ 49 $ 39,402 Year ended December 31, 2016 Balance at the beginning of year $ 10,573 $ 13,007 $ 2,339 $ 769 $ 215 $ 164 $ 8 $ (32 ) $ 27,043 Provision for loan losses 2,391 5,436 810 532 (8 ) 97 90 92 9,440 Charge-offs (4,384 ) (54 ) (401 ) — — (27 ) (104 ) — (4,970 ) Recoveries 13 10 12 — — 8 35 — 78 Balance at the end of year $ 8,593 $ 18,399 $ 2,760 $ 1,301 $ 207 $ 242 $ 29 $ 60 $ 31,591 The following table details the amount of the allowance for loan losses and recorded investment in loans by class as of December 31, 2018 and 2017 : Commercial Commercial Residential Real Estate Single-Family Interim Construction Agricultural Consumer Other Unallocated Total December 31, 2018 Allowance for losses: Individually evaluated for impairment $ 2,633 $ — $ 92 $ — $ — $ 2 $ — $ — $ 2,727 Collectively evaluated for impairment 9,115 27,795 3,228 1,402 241 184 3 62 42,030 Loans acquired with deteriorated credit quality 45 — — — — — — — 45 Ending balance $ 11,793 $ 27,795 $ 3,320 $ 1,402 $ 241 $ 186 $ 3 $ 62 $ 44,802 Loans: Individually evaluated for impairment $ 7,288 $ 1,734 $ 1,943 $ 3,578 $ — $ 32 $ — $ — $ 14,575 Collectively evaluated for impairment 1,335,194 4,955,178 1,044,265 328,170 66,032 31,699 253 — 7,760,791 Acquired with deteriorated credit quality 18,622 89,865 3,313 — 606 28 — — 112,434 Ending balance $ 1,361,104 $ 5,046,777 $ 1,049,521 $ 331,748 $ 66,638 $ 31,759 $ 253 $ — $ 7,887,800 December 31, 2017 Allowance for losses: Individually evaluated for impairment $ 3,500 $ 311 $ — $ — $ — $ 2 $ — $ — $ 3,813 Collectively evaluated for impairment 7,099 22,990 3,447 1,583 250 203 (32 ) 49 35,589 Loans acquired with deteriorated credit quality — — — — — — — — — Ending balance $ 10,599 $ 23,301 $ 3,447 $ 1,583 $ 250 $ 205 $ (32 ) $ 49 $ 39,402 Loans: Individually evaluated for impairment $ 10,297 $ 3,054 $ 1,727 $ — $ — $ 74 $ — $ — $ 15,152 Collectively evaluated for impairment 1,037,401 4,039,332 887,292 289,680 78,646 34,544 304 — 6,367,199 Acquired with deteriorated credit quality 12,286 72,374 3,274 — 3,937 21 — — 91,892 Ending balance $ 1,059,984 $ 4,114,760 $ 892,293 $ 289,680 $ 82,583 $ 34,639 $ 304 $ — $ 6,474,243 Nonperforming loans by loan class (excluding loans acquired with deteriorated credit quality) at December 31, 2018 and 2017 , are summarized as follows: Commercial Commercial Residential Real Estate Single-Family Interim Construction Agricultural Consumer Other Total December 31, 2018 Nonaccrual loans $ 5,224 $ 1,329 $ 1,775 $ 3,578 $ — $ 32 $ — $ 11,938 Loans past due 90 days and still accruing — — — — — 5 — 5 Troubled debt restructurings (not included in nonaccrual or loans past due and still accruing) 114 405 168 — — — — 687 $ 5,338 $ 1,734 $ 1,943 $ 3,578 $ — $ 37 $ — $ 12,630 December 31, 2017 Nonaccrual loans $ 10,304 $ 2,716 $ 998 $ — $ — $ 55 $ — $ 14,073 Loans past due 90 days and still accruing 8 120 8 — — — — 136 Troubled debt restructurings (not included in nonaccrual or loans past due and still accruing) — 455 730 — — 20 — 1,205 $ 10,312 $ 3,291 $ 1,736 $ — $ — $ 75 $ — $ 15,414 The accrual of interest is discontinued on a loan when management believes, after considering collection efforts and other factors that the borrower's financial condition, is such that collection of interest is doubtful. All interest accrued but not collected for loans that are placed on nonaccrual status or charged-off is reversed against interest income. Cash collections on nonaccrual loans are generally credited to the loan receivable balance, and no interest income is recognized on those loans until the principal balance has been collected. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Impaired loans are those loans where it is probable that all amounts due according to contractual terms of the loan agreement will not be collected. The Company has identified these loans through its normal loan review procedures. Impaired loans are measured based on 1) the present value of expected future cash flows discounted at the loans effective interest rate; 2) the loan's observable market price; or 3) the fair value of collateral if the loan is collateral dependent. Substantially all of the Company’s impaired loans are measured at the fair value of the collateral. In limited cases, the Company may use other methods to determine the level of impairment of a loan if such loan is not collateral dependent. All commercial, real estate, agricultural loans and troubled debt restructurings are considered for individual impairment analysis. Smaller balance consumer loans are collectively evaluated for impairment. Impaired loan information by loan class (excluding loans acquired with deteriorated credit quality) at December 31, 2018 and 2017 and for the years ended December 31, 2018 , 2017 and 2016 , is summarized as follows: Commercial Commercial Residential Real Estate Single-Family Interim Construction Agricultural Consumer Other Total December 31, 2018 Recorded investment in impaired loans: Impaired loans with an allowance for loan losses $ 6,416 $ — $ 134 $ — $ — $ 1 $ — $ 6,551 Impaired loans with no allowance for loan losses 872 1,734 1,809 3,578 — 31 — 8,024 Total $ 7,288 $ 1,734 $ 1,943 $ 3,578 $ — $ 32 $ — $ 14,575 Unpaid principal balance of impaired loans $ 9,822 $ 1,860 $ 2,056 $ 3,579 $ — $ 38 $ — $ 17,355 Allowance for loan losses on impaired loans $ 2,633 $ — $ 92 $ — $ — $ 2 $ — $ 2,727 December 31, 2017 Recorded investment in impaired loans: Impaired loans with an allowance for loan losses $ 9,255 $ 1,793 $ — $ — $ — $ 2 $ — $ 11,050 Impaired loans with no allowance for loan losses 1,042 1,261 1,727 — — 72 — 4,102 Total $ 10,297 $ 3,054 $ 1,727 $ — $ — $ 74 $ — $ 15,152 Unpaid principal balance of impaired loans $ 13,456 $ 3,124 $ 1,818 $ — $ — $ 197 $ — $ 18,595 Allowance for loan losses on impaired loans $ 3,500 $ 311 $ — $ — $ — $ 2 $ — $ 3,813 For the year ended December 31, 2018 Average recorded investment in impaired loans $ 8,919 $ 2,667 $ 2,033 $ 716 $ — $ 46 $ — $ 14,381 Interest income recognized on impaired loans $ 119 $ 65 $ 81 $ 1 $ — $ 2 $ — $ 268 For the year ended December 31, 2017 Average recorded investment in impaired loans $ 8,524 $ 3,690 $ 2,431 $ 177 $ — $ 218 $ — $ 15,040 Interest income recognized on impaired loans $ 8 $ 428 $ 58 $ — $ — $ 5 $ — $ 499 For the year ended December 31, 2016 Average recorded investment in impaired loans $ 11,783 $ 3,324 $ 2,773 $ 177 $ 34 $ 118 $ — $ 18,209 Interest income recognized on impaired loans $ 58 $ 73 $ 97 $ — $ — $ — $ — $ 228 Certain impaired loans have adequate collateral and do not require a related allowance for loan loss. The Company will charge off that portion of any loan which management considers a loss. Commercial and real estate loans are generally considered for charge-off when exposure beyond collateral coverage is apparent and when no further collection of the loss portion is anticipated based on the borrower’s financial condition. The restructuring of a loan is considered a “troubled debt restructuring” if both 1) the borrower is experiencing financial difficulties and 2) the creditor has granted a concession. Concessions may include interest rate reductions or below market interest rates, principal forgiveness, extending amortization and other actions intended to minimize potential losses. A “troubled debt restructured” loan is identified as impaired and measured for credit impairment as of each reporting period in accordance with the guidance in ASC 310-10-35. Modifications primarily relate to extending the amortization periods of the loans and interest rate concessions. The majority of these loans were identified as impaired prior to restructuring; therefore, the modifications did not materially impact the Company’s determination of the allowance for loan losses. The recorded investment in troubled debt restructurings, including those on nonaccrual, was $1,925 and $3,028 as of December 31, 2018 and 2017 , respectively. Following is a summary of loans modified under troubled debt restructurings during the years ended December 31, 2018 and 2017 : Commercial Commercial Residential Real Estate Single-Family Interim Construction Agricultural Consumer Other Total Troubled debt restructurings during the year ended December 31, 2018 Number of contracts 1 — — — — — — 1 Pre-restructuring outstanding recorded investment $ 114 $ — $ — $ — $ — $ — $ — $ 114 Post-restructuring outstanding recorded investment $ 114 $ — $ — $ — $ — $ — $ — $ 114 Troubled debt restructurings during the year ended December 31, 2017 Number of contracts 1 — 1 — — 1 — 3 Pre-restructuring outstanding recorded investment $ 873 $ — $ 465 $ — $ — $ 22 $ — $ 1,360 Post-restructuring outstanding recorded investment $ 873 $ — $ 465 $ — $ — $ 22 $ — $ 1,360 At December 31, 2018 and 2017 , there were no loans modified under troubled debt restructurings during the previous twelve month period that subsequently defaulted during the years ended December 31, 2018 and 2017 . At December 31, 2018 and 2017 , the Company had no commitments to lend additional funds to any borrowers with loans whose terms have been modified under troubled debt restructurings. Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due.

The loans placed in the Pass/Watch category reflect the Company’s opinion that the loans reflect potential weakness which requires monitoring on a more frequent basis. The loans in the Special Mention category reflect the Company’s opinion that the credit contains weaknesses which represent a greater degree of risk and warrant extra attention. These loans are reviewed monthly by officers and senior management to determine if a change in category is warranted. The loans placed in the Substandard category are considered to be potentially inadequately protected by the current debt service capacity of the borrower and/or the pledged collateral. These credits, even if apparently protected by collateral value, have shown weakness related to adverse financial, managerial, economic, market or political conditions which may jeopardize repayment of principal and interest. There is possibility that some future loss could be sustained by the Company if such weakness is not corrected. The Doubtful category includes loans that are in default or principal exposure is probable. Substandard and Doubtful loans are individually evaluated to determine if they should be classified as impaired and an allowance is allocated if deemed necessary under ASC 310-10. The loans that are not impaired are included with the remaining “pass” credits in determining the portion of the allowance for loan loss based on historical loss experience and other qualitative factors. The portfolio is segmented into categories including: commercial loans, consumer loans, commercial real estate loans, residential real estate loans and agricultural loans. The adjusted historical loss percentage is applied to each category. Each category is then added together to determine the allowance allocated under ASC 450-20. A summary of loans by credit quality indicator by class as of December 31, 2018 and 2017 , is as follows: Pass Pass/ Watch Special Mention Substandard Doubtful Total December 31, 2018 Commercial $ 1,279,024 $ 18,378 $ 30,783 $ 32,919 $ — $ 1,361,104 Commercial real estate, construction, land and land development 4,895,217 81,693 40,601 29,266 — 5,046,777 Residential real estate 1,038,283 3,617 707 6,914 — 1,049,521 Single-family interim construction 327,939 — 231 3,578 — 331,748 Agricultural 61,055 2,918 2,093 572 — 66,638 Consumer 31,559 67 — 133 — 31,759 Other 253 — — — — 253 $ 7,633,330 $ 106,673 $ 74,415 $ 73,382 $ — $ 7,887,800 December 31, 2017 Commercial $ 989,953 $ 35,105 $ 3,737 $ 31,189 $ — $ 1,059,984 Commercial real estate, construction, land and land development 4,040,385 46,288 11,915 16,172 — 4,114,760 Residential real estate 883,653 2,722 462 5,456 — 892,293 Single-family interim construction 288,020 1,660 — — — 289,680 Agricultural 59,392 5,762 13,802 3,627 — 82,583 Consumer 34,510 25 4 100 — 34,639 Other 304 — — — — 304 $ 6,296,217 $ 91,562 $ 29,920 $ 56,544 $ — $ 6,474,243 The Company has acquired certain loans which experienced credit deterioration since origination (purchase credit impaired (PCI) loans).

Junior Subordinated Debentures | Junior Subordinated Debentures The Company has formed or acquired seven statutory business trusts under the laws of the State of Delaware for the purpose of issuing trust preferred securities. The statutory business trusts formed or acquired by the Company (the "Trusts") have each issued capital and common securities and invested the proceeds thereof in an equivalent amount of junior subordinated debentures (the "Debentures") issued by the Company. The interest rate payable on, and the payment terms of the Debentures are the same as the distribution rate and payment terms of the respective issues of capital and common securities issued by the Trusts. The Debentures are subordinated and junior in right of payment to all present and future senior indebtedness. The Company has fully and unconditionally guaranteed the obligations of each of the Trusts with respect to the capital and common securities. Except under certain circumstances, the common securities issued to the Company by the trusts possess sole voting rights with respect to matters involving those entities. Under certain circumstances, the Company may, from time to time, defer the debentures' interest payments, which would result in a deferral of distribution payments on the related trust preferred securities and, with certain exceptions, prevent the Company from declaring or paying cash distributions on the Company's common stock and any other future debt ranking equally with or junior to the debentures. As of December 31, 2018 and 2017 , the carrying amount of debentures outstanding totaled $27,852 and $27,654 , respectively. As a result of the Carlile acquisition during 2017 (see Note 21 , Business Combinations), the Company assumed subordinated obligations for two statutory Trusts. At acquisition date, the total debt for these two Trusts was recorded at fair value with a recorded discount totaling $4,045 , which will be amortized back to par value over the estimated lives of the instruments. During 2018 and 2017, $198 and $149 , respectively, was amortized into interest expense related to the discount recorded.

Income tax expense for the years ended December 31, 2018 , 2017 and 2016 was as follows: Years ended December 31, 2018 2017 2016 Current income tax expense $ 29,801 $ 28,121 $ 28,440 Deferred income tax expense (benefit) 2,000 11,526 (1,849 ) Deferred income tax (benefit) expense related to remeasurement of deferred taxes (63 ) 5,528 — Income tax expense, as reported $ 31,738 $ 45,175 $ 26,591 A reconciliation between reported income tax expense and the amounts computed by applying the U.S. federal statutory income tax rate of 21% for the year ended December 31, 2018 and 35% for the years ended December 31, 2017 and 2016 to income before income taxes is presented below: Years ended December 31, 2018 2017 2016 Income tax expense computed at the statutory rate $ 33,599 $ 42,590 $ 28,046 Tax-exempt interest income from municipal securities (962 ) (1,357 ) (619 ) Tax-exempt loan income (490 ) (435 ) (436 ) Bank owned life insurance income (666 ) (962 ) (472 ) Non-deductible acquisition expenses 142 491 — State taxes, net of federal benefit 375 241 — Net tax benefit from stock based compensation (646 ) (1,323 ) — Deferred tax adjustment related to reduction in U.S. Federal statutory income tax rate (63 ) 5,528 — Other 449 402 72 $ 31,738 $ 45,175 $ 26,591 As ASC 740, Income Taxes , requires the effects of changes in tax rates and laws on deferred tax balances to be recognized in the period in which the legislation is enacted, the Company remeasured its deferred tax assets and liabilities based upon the newly enacted U.S. statutory federal income tax rate of 21%, which is the tax rate at which these assets and liabilities are expected to reverse in the future and, as noted above, recognized a tax expense related to the remeasurement of $5,528 in 2017. In accordance with the SEC Staff Accounting Bulletin No. 118 (SAB 118), which provides for a one year measurement period from the Tax Act enactment date for companies to complete the accounting under ASC 740, Income Taxes , an additional net tax benefit resulting from the finalization of those calculations of $63 was recorded in 2018. Components of deferred tax assets and liabilities are presented in the table below. As a result of the Tax Cuts and Jobs Act, deferred taxes as of December 31, 2018 and 2017 are based on the newly enacted U.S. statutory federal income tax rate of 21%. December 31, 2018 2017 Deferred tax assets: Allowance for loan losses $ 9,496 $ 8,365 NOL and tax credit carryforwards from acquisitions 4,810 6,791 Net unrealized loss on available for sale securities 2,365 349 Acquired loan fair market value adjustments 6,090 5,214 Restricted stock 987 791 Reserve for bonuses 1,646 479 Deferred loan fees 700 545 Securities 273 265 Start up costs 274 281 Other real estate owned 273 402 Unearned bankcard income 160 244 Deferred compensation 1,266 492 Noncompete agreements 552 526 Nonaccrual loans 470 414 Other 303 310 29,665 25,468 Deferred tax liabilities: Premises and equipment (5,242 ) (5,128 ) Core deposit intangibles (9,547 ) (9,181 ) Acquired junior subordinated debentures fair value adjustment (777 ) (818 ) FHLB stock (250 ) (204 ) Prepaids (190 ) (153 ) Acquired tax goodwill (232 ) (111 ) Other (247 ) (110 ) (16,485 ) (15,705 ) Net deferred tax asset $ 13,180 $ 9,763 At December 31, 2018 , the Company had federal net operating loss carryforwards of approximately $18,822 which expire in various years from 2021 to 2032, federal tax credit carryovers of approximately $132 which will never expire and state net operating loss carryforwards of approximately $19,821 which expire in various years from 2030 to 2036. Deferred tax assets are recognized for net operating losses because the benefit is more likely than not to be realized. No valuation allowance for deferred tax assets was recorded at December 31, 2018 or 2017 as management believes it is more likely than not that all of the deferred tax assets will be realized. The Company does not have any material uncertain tax positions and does not have any interest and penalties recorded in the income statement for the years ended December 31, 2018 , 2017 and 2016 . The Company files a consolidated income tax return in the US federal tax jurisdiction. The Company is no longer subject to examination by the US federal tax jurisdiction for years prior to 2015. |

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | Commitments and Contingencies Financial Instruments with Off-Balance Sheet Risk The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. The commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the balance sheet. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit is represented by the contractual amount of this instrument. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. At December 31, 2018 and 2017 , the approximate amounts of these financial instruments were as follows: December 31, 2018 2017 Commitments to extend credit $ 1,761,724 $ 1,286,704 Standby letters of credit 14,997 10,532 $ 1,776,721 $ 1,297,236 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained if deemed necessary by the Company upon extension of credit is based on management’s credit evaluation of the counterparty. Collateral held varies but may include accounts receivable, inventory, farm crops, property, plant and equipment and income-producing commercial properties. Letters of credit are written conditional commitments used by the Company to guarantee the performance of a customer to a third party. The Company’s policies generally require that letter of credit arrangements contain security and debt covenants similar to those contained in loan arrangements. In the event the customer does not perform in accordance with the terms of the agreement with the third party, the Company would be required to fund the commitment. The maximum potential amount of future payments the Company could be required to make is represented by the contractual amount shown in the table above. If the commitment is funded, the Company would be entitled to seek recovery from the customer. As of December 31, 2018 and 2017 , no amounts have been recorded as liabilities for the Company’s potential obligations under these guarantees. Litigation The Company is involved in certain legal actions arising from normal business activities. Management believes that the outcome of such proceedings will not materially affect the financial position, results of operations or cash flows of the Company. A legal proceeding that the Company believes could become material is described below. Independent Bank is a party to a legal proceeding inherited by Independent Bank in connection with its acquisition of BOH Holdings, Inc. and its subsidiary, Bank of Houston (BOH). The plaintiffs in the case are alleging that Independent Bank aided and abetted or participated in a fraudulent scheme. Independent Bank is pursuing insurance coverage for these claims, including reimbursement for defense costs. The Company believes the claims made in this lawsuit are without merit and is vigorously defending the lawsuit. The Company is unable to predict when the matter will be resolved, the ultimate outcome or potential costs or damages to be incurred. Please see Part I, Item 3. for more details on this lawsuit. Lease Commitments The Company leases certain branch facilities and other facilities. Rent expense related to these leases amounted to $ 3,758 , $ 3,073 and $ 2,114 for the years ended December 31, 2018 , 2017 and 2016 , respectively. At December 31, 2018 , minimum future rental payments due under noncancelable lease commitments were as follows: First year $ 3,968 Second year 3,853 Third year 3,698 Fourth year 3,221 Fifth year 2,502 Thereafter 7,863 $ 25,105 It is expected that certain leases will be renewed as these leases expire. T he Company leases office space in certain locations to other unaffiliated tenants. Rental income of $456 was recognized during 2018. This rental income is recorded in the consolidated statement of income as an offset to occupancy expense. Aggregate future minimum rentals to be received under noncancelable subleases greater than one year at December 31, 2018, were $1,311 . During third quarter 2018, the Company sold its existing corporate headquarters to an unaffiliated third party and executed a five year leaseback with the buyer. In connection with the sale and subsequent leaseback, the Company agreed to a prepayment of $7,822 which represents $5,222 in base rent and $2,600 in operating expenses, as defined under the terms of the lease. Such prepaid is reflected in other assets in the consolidated balance sheet and totaled $7,375 , of which $4,931 relates to base rent, as of December 31, 2018. The base rent prepaid has been excluded from the above table of minimum future rental payments due under noncancelable leases. |

Employee Benefit Plans | Employee Benefit Plans The Company has a 401(k) profit sharing plan (Plan) which covers employees over the age of eighteen who have completed ninety days of credited service, as defined by the Plan. The Plan provides for “before tax” employee contributions through salary reduction contributions under Section 401(k) of the Internal Revenue Code. A participant may choose a salary reduction not to exceed the dollar limit set by law each year ( $18.5 in 2018). Contributions by the Company and by participants are immediately fully vested. In July 2018, the Plan was modified to provide for the Company to make 401(k) matching contributions of 100% , but limited to 6% of the participant's eligible salary. Previously, the Plan provided for the Company to make 401(k) matching contributions ranging from 50% to 100% depending upon the employee's years of service, but limited to 6% of the participant's eligible salary. The Plan also provides for the Company to make additional discretionary contributions to the Plan. The Company made contributions of approximately $ 3,280 , $ 2,070 and $ 1,393 for the years ended December 31, 2018 , 2017 and 2016 , respectively. |

Fair Value Disclosures [Abstract] | |
Fair Value Measurements | Fair Value Measurements The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. In estimating fair value, the Company utilizes valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. Such valuation techniques are consistently applied. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. ASC Topic 820, Fair Value Measurements and Disclosures , 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 might 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 (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means. Level 3 Inputs – Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities. The Company elected the fair value option for certain residential mortgage loans held for sale originated after July 1, 2018 in accordance with ASC 825, Financial Instruments. This election allows for a more effective offset of the changes in fair values of the loans and the derivative instruments used to economically hedge them without the burden of complying with the requirements for hedge accounting under ASC 815, Derivatives and Hedging . The Company has not elected the fair value option for other residential mortgage loans held for sale primarily because they are not economically hedged using derivative instruments. See below and Note 18 , Derivative Financial Instruments, for additional information. Assets and Liabilities Measured on a Recurring Basis The following table represents assets and liabilities reported on the consolidated balance sheets at their fair value on a recurring basis as of December 31, 2018 and 2017 by level within the ASC Topic 820 fair value measurement hierarchy: Fair Value Measurements at Reporting Date Using Assets/ Liabilities Measured at Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) December 31, 2018 Assets: Investment securities available for sale: U.S. treasuries $ 29,643 $ — $ 29,643 $ — Government agency securities 150,230 — 150,230 — Obligations of state and municipal subdivisions 185,007 — 185,007 — Residential pass-through securities guaranteed by FNMA, GNMA, and FHLMC 320,470 — 320,470 — Total investment securities available for sale $ 685,350 $ — $ 685,350 $ — Loans held for sale, fair value option elected (1) $ 27,871 $ — $ 27,871 $ — Derivative financial instruments: Interest rate lock commitments 822 — 822 — Loan customer counterparty 360 — 360 — Financial institution counterparty 109 — 109 — Liabilities: Derivative financial instruments: Forward mortgage-backed securities trades 226 — 226 — Loan customer counterparty 108 — 108 — Financial institution counterparty 406 — 406 — December 31, 2017 Assets: Investment securities available for sale: U.S. treasuries $ 37,154 $ — $ 37,154 $ — Government agency securities 211,509 — 211,509 — Obligations of state and municipal subdivisions 229,613 — 229,613 — Residential pass-through securities guaranteed by FNMA, GNMA, FHLMC, FHR and GNR 274,377 — 274,377 — Other securities 10,349 10,349 — — Total investment securities available for sale $ 763,002 $ 10,349 $ 752,653 $ — (1) At December 31, 2018 , loans held for sale for which the fair value option was elected had an aggregate outstanding principal balance of $26,594 . There were no mortgage loans held for sale under the fair value option that were 90 days or greater past due or on nonaccrual at December 31, 2018 . There were no transfers between level categorizations and no changes in valuation methodologies for the years presented. A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. Securities classified as available for sale are reported at fair value utilizing Level 1 and Level 2 inputs. Securities are classified within Level 1 when quoted market prices are available in an active market. Inputs include securities that have quoted prices in active markets for identical assets. For securities utilizing Level 2 inputs, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury and other yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the security’s terms and conditions, among other things. Certain mortgage loans held for sale are measured at fair value on a recurring basis due to the Company's election to adopt fair value accounting treatment for those loans originated after July 1, 2018 for which the Company has entered into certain derivative financial instruments as part of its mortgage banking and related risk management activities. These instruments include interest rate lock commitments and mandatory forward commitments to sell these loans to investors known as forward mortgage-backed securities trades. Such mortgage loans held for sale, which are sold on a servicing released basis, are valued using a market approach by utilizing either: (i) the fair value of 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 to 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. For mortgage loans held for sale for which the fair value option was elected, the earned current contractual interest payment is recognized in interest income, loan origination costs and fees on fair value option loans are recognized in earnings as incurred and not deferred. The Company has no continuing involvement in any residential mortgage loans sold. The estimated fair values of interest rate lock commitments utilize 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 interest rate lock commitments 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, as the valuations are based on observable market inputs. Forward mortgage-backed securities trades are exchange-traded or traded within highly active dealer markets. In order to determine the fair value of these instruments, the Company utilized the exchange price or dealer market price for the particular derivative contract; therefore these contracts are classified as Level 2. The estimated fair values are subject to change primarily due to changes in interest rates. The Company also enters into certain interest rate derivative positions that are not designated as hedging instruments. The estimated fair value of these commercial loan interest rate swaps are obtained from a pricing service that provides the swaps' unwind value (Level 2 inputs). See Note 18 , Derivative Financial Instruments, for more information. Assets and Liabilities Measured on a Nonrecurring Basis In accordance with ASC Topic 820, certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the assets and liabilities 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). The following table presents the assets carried on the consolidated balance sheet by caption and by level in the fair value hierarchy at December 31, 2018 and 2017 , for which a nonrecurring change in fair value has been recorded: Fair Value Measurements at Reporting Date Using Assets/ Liabilities Measured at Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Period Ended Total Losses December 31, 2018 Assets: Impaired loans $ 3,824 $ — $ — $ 3,824 $ 2,227 December 31, 2017 Assets: Impaired loans $ 7,237 $ — $ — $ 7,237 $ 3,719 Other real estate owned 1,726 — — 1,726 375 Impaired loans (loans which are not expected to repay all principal and interest amounts due in accordance with the original contractual terms) are measured at an observable market price (if available) or at the fair value of the loan’s collateral (if collateral dependent). Fair value of the loan’s collateral is determined by appraisals or independent valuation which is then adjusted for the estimated costs related to liquidation of the collateral. Management’s ongoing review of appraisal information may result in additional discounts or adjustments to valuation based upon more recent market sales activity or more current appraisal information derived from properties of similar type and/or locale. Therefore, the Company has categorized its impaired loans as Level 3. Other real estate is measured at fair value on a nonrecurring basis (upon initial recognition or subsequent impairment). Other real estate owned is classified within Level 3 of the valuation hierarchy. When transferred from the loan portfolio, other real estate owned is adjusted to fair value less estimated selling costs and is subsequently carried at the lower of carrying value or fair value less estimated selling costs. The fair value is determined using an external appraisal process, discounted based on internal criteria. Therefore, the Company has categorized its other real estate as Level 3. In addition, mortgage loans held for sale not recorded under the fair value option are required to be measured at the lower of cost or fair value. The fair value of these loans is based upon binding quotes or bids from third party investors. As of December 31, 2018 and 2017 , all mortgage loans held for sale not recorded under the fair value option were recorded at cost. Fair Value of Financial Instruments not Recorded at Fair Value The carrying amount, estimated fair value and the level of the fair value hierarchy of the Company’s financial instruments that are reported at amortized cost on the Company's consolidated balance sheets were as follows at December 31, 2018 and 2017 : Fair Value Measurements at Reporting Date Using Carrying Amount Estimated Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) December 31, 2018 Financial assets: Cash and cash equivalents $ 130,779 $ 130,779 $ 130,779 $ — $ — Certificates of deposit held in other banks 1,225 1,224 — 1,224 — Loans held for sale, at cost 4,856 4,974 — 4,974 — Loans, net 7,839,695 7,807,823 — 7,803,999 3,824 FHLB of Dallas stock and other restricted stock 26,870 26,870 — 26,870 — Accrued interest receivable 24,253 24,253 — 24,253 — Financial liabilities: Deposits 7,737,794 7,750,059 — 7,750,059 — Accrued interest payable 6,183 6,183 — 6,183 — FHLB advances 290,000 287,450 — 287,450 — Other borrowings 137,316 138,450 — 138,450 — Junior subordinated debentures 27,852 31,370 — 31,370 — Off-balance sheet assets (liabilities): Commitments to extend credit — — — — — Standby letters of credit — — — — — December 31, 2017 Financial assets: Cash and cash equivalents $ 431,102 $ 431,102 $ 431,102 $ — $ — Certificates of deposit held in other banks 12,985 13,049 — 13,049 — Loans held for sale, at cost 39,202 40,436 — 40,436 — Loans, net 6,432,273 6,350,416 — 6,343,179 7,237 FHLB of Dallas stock and other restricted stock 29,184 29,184 — 29,184 — Accrued interest receivable 20,835 20,835 — 20,835 — Financial liabilities: Deposits 6,632,822 6,637,813 — 6,637,813 — Accrued interest payable 4,654 4,654 — 4,654 — FHLB advances 530,667 526,514 — 526,514 — Other borrowings 136,911 141,650 — 141,650 — Junior subordinated debentures 27,654 20,008 — 20,008 — Off-balance sheet assets (liabilities): Commitments to extend credit — — — — — Standby letters of credit — — — — — The methods and assumptions used by the Company in estimating fair values of financial instruments as disclosed herein in accordance with ASC Topic 825, Financial Instruments , as amended by ASU 2016-01 requiring public entities to use the exit price notion effective January 1, 2018, other than for those measured at fair value on a recurring and nonrecurring basis discussed above, are as follows: Cash and cash equivalents: The carrying amounts of cash and cash equivalents approximate their fair value. Certificates of deposit held in other banks: The fair value of certificates of deposit held in other banks is based upon current market rates. Loans held for sale, at cost: The fair value of loans held for sale is determined based upon commitments on hand from investors. Loans: Pursuant to the adoption of ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, for loan values reported for the 2018 period, a discounted cash flow model is used to estimate the fair value of the loans. The discounted cash flow approach models the credit losses directly in the projected cash flows, applying various assumptions regarding credit, interest, and prepayment risks for the loans based on loan types, payment types and fixed or variable classifications. Loans reported prior to 2018 were valued as follows: For variable-rate loans that reprice frequently and have no significant changes in credit risk, fair values are based on carrying values. Fair values for certain mortgage loans (for example, one-to-four family residential), commercial real estate and commercial loans are estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. Federal Home Loan Bank of Dallas and other restricted stock: The carrying value of restricted securities such as stock in the Federal Home Loan Bank of Dallas and Independent Bankers Financial Corporation approximates fair value. Deposits: The fair values disclosed for demand deposits are, by definition, equal to the amount payable on demand at the reporting date (that is their carrying amounts). The carrying amounts of variable-rate certificates of deposit (CDs) approximate their fair values at the reporting date. Fair values for fixed-rate CDs are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits. Federal Home Loan Bank advances, line of credit and federal funds purchased: The fair value of advances maturing within 90 days approximates carrying value. Fair value of other advances is based on the Company’s current borrowing rate for similar arrangements. Other borrowings: The carrying value of repurchase agreements approximates fair value due to the short term nature. The fair value of private subordinated debentures are based upon prevailing rates on similar debt in the market place. The subordinated debentures that are publicly traded are valued based on indicative bid prices based upon market pricing observations in the current market. Junior subordinated debentures: The fair value of junior subordinated debentures is estimated using discounted cash flow analyses based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements. Accrued interest: The carrying amounts of accrued interest approximate their fair values. Off-balance sheet instruments: Fair values for off-balance sheet, credit-related financial instruments are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties' credit standing. The fair value of commitments is not material. |

Derivative Instruments and Hedging Activities Disclosure [Abstract] | |
Derivative Financial Instruments | Derivative Financial Instruments The Company enters into certain derivative financial instruments as part of its hedging strategy. These financial instruments are not designated as hedging instruments and are used for asset and liability management related to the Company's mortgage banking activities and commercial customers' financing needs. All derivatives are carried at fair value in either other assets or other liabilities. Through the normal course of business, the Company enters into interest rate lock commitments with consumers to originate mortgage loans at a specified interest rate. 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. During July 2018, the Company began managing the changes in fair value associated with changes in interest rates related to interest rate lock commitments by using forward sold commitments known as forward mortgage-backed securities trades. These instruments are typically entered into at the time the interest rate lock commitment is made. The Company also offers certain derivatives products, primarily interest rate swaps, directly to qualified commercial banking customers to facilitate their risk management strategies. The interest rate swap derivative positions relate to transactions in which the Company enters into an interest rate swap with a customer, while at the same time entering into an offsetting interest rate swap with another financial institution. An interest rate swap transaction allows customers to effectively convert a variable rate loan to a fixed rate. In connection with each swap, the Company agrees to pay interest to the customer on a notional amount at a variable interest rate and receive interest from the customer on a similar notional amount at a fixed interest rate. At the same time, the Company agrees to pay another financial institution the same fixed interest rate on the same notional amount and receive the same variable interest rate on the same notional amount. These products were not significant for disclosure in prior periods. The following table provides the outstanding notional balances and fair values of outstanding derivative positions at December 31, 2018 : December 31, 2018 Outstanding Notional Balance Asset Derivative Fair Value Liability Derivative Fair Value Interest rate lock commitments $ 20,306 $ 822 $ — Forward mortgage-backed securities trades 27,500 — 226 Commercial loan interest rate swaps: Loan customer counterparty 25,055 360 108 Financial institution counterparty 25,055 109 406 The credit exposure related to interest rate swaps is limited to the net favorable value of all swaps by each counterparty, which was approximately $469 at December 31, 2018 . The initial and subsequent changes in the fair value of interest rate lock commitments and the forward sales of mortgage-back securities are recorded in mortgage banking revenue.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract] | |
Stock Awards and Stock Warrants | Stock Awards and Stock Warrants The Company grants common stock awards to certain employees of the Company. The common stock awards issued prior to 2013 vest five years from the date the award was granted and the related compensation expense is recognized over the vesting period. In connection with the Company's initial public offering in April 2013, the Board of Directors adopted the 2013 Equity Incentive Plan. Under this plan, the Compensation Committee may grant awards in the form of restricted stock, restricted stock rights, restricted stock units, qualified and nonqualified stock options, performance-based share awards and other equity-based awards. In May 2018, the shareholders of the Company voted to amend the plan to increase the reserved shares of common stock to be awarded by the Company's compensation committee by 1,500,000 for a total of 2,300,000 reserved shares. As of December 31, 2018 , there were 1,581,608 shares remaining available for grant for future awards. The shares currently issued under the 2013 Plan are restricted and will vest evenly over the required employment period, generally ranging from three to five years. Shares granted under a previous plan prior to 2012 and those in and subsequent to 2013 under the 2013 Equity Incentive Plan were issued at the date of grant and receive dividends. Shares issued under a revised plan in 2012 are not outstanding shares of the Company until they vest and do not receive dividends. During the year ended December 31, 2017, 25,760 shares that were issued under the 2012 Plan vested during the period. All stock awards issued under expired plans prior to 2013 are fully vested. The following table summarizes the activity in nonvested shares for the years ended December 31, 2018 and 2017 : Number of Shares Weighted Average Grant Date Fair Value Nonvested shares, December 31, 2017 242,056 $ 49.17 Granted during the period 130,212 71.85 Vested during the period (115,520 ) 44.36 Forfeited during the period (3,845 ) 64.47 Nonvested shares, December 31, 2018 252,903 $ 62.81 Nonvested shares, December 31, 2016 280,524 $ 36.88 Granted during the period 104,962 61.89 Vested during the period (140,887 ) 34.18 Forfeited during the period (2,543 ) 48.29 Nonvested shares, December 31, 2017 242,056 $ 49.17 Compensation expense related to these awards is recorded based on the fair value of the award at the date of grant and totaled $6,062 , $4,688 and $5,431 for the years ended December 31, 2018 , 2017 and 2016 , respectively. Compensation expense is recorded in salaries and employee benefits in the accompanying consolidated statements of income. At December 31, 2018 , future compensation expense is estimated to be $11,186 and will be recognized over a remaining weighted average period of 3.09 years. The fair value of common stock awards that vested during the years ended December 31, 2018 , 2017 and 2016 was $8,206 , $8,597 and $5,208 , respectively. The Company has recorded $646 and $1,323 in excess tax benefits on vested restricted stock to income tax expense for the years ended December 31, 2018 and 2017 , respectively. The Company recorded $(137) to additional paid in capital, which represents the income tax deficiency recognized on the vested shares for the year ended December 31, 2016 . There were no modifications of stock agreements during 2018 , 2017 and 2016 that resulted in significant additional incremental compensation costs. At December 31, 2018 , the future vesting schedule of the nonvested shares is as follows: First year 108,883 Second year 59,344 Third year 42,620 Fourth year 24,876 Fifth year 17,180 Total nonvested shares 252,903 The Company had issued warrants representing the right to purchase 150,544 shares of Company stock at $17.19 per share to certain Company directors and shareholders. The warrants were issued in return for the shareholders' agreement to repurchase the subordinated debt outstanding to an unaffiliated bank in the event of Company default. The warrants were recorded as equity awards at fair value and were being amortized over the term of the debt. The subordinated debt was paid off by the Company in 2013. The warrants expired in December 2018 and all warrants were exercised before the expiration date. During the years ended December 31, 2018 and 2017 , warrants to purchase 147,341 and 3,203 shares of common stock were exercised and have been issued by the Company, respectively. |

Regulated Operations [Abstract] | |
Regulatory Matters | Regulatory Matters Under banking law, there are legal restrictions limiting the amount of dividends the Bank can declare. Approval of the regulatory authorities is required if the effect of dividends declared would cause the regulatory capital of the Bank to fall below specified minimum levels. For state banks, subject to regulatory capital requirements, payment of dividends is generally allowed to the extent of net profits. The Company (on a consolidated basis) and the Bank are subject to various regulatory capital requirements administered by federal and state 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 consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. The Company is subject to the Basel III regulatory capital framework (the "Basel III Capital Rules"). The implementation of the capital conservation buffer became effective for the Company on January 1, 2016 at the 0.625% level and increasing 0.625% each year thereafter, until it reaches 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 full 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. When fully phased in on January 1, 2019, the Basel III Capital Rules will require the Company and Bank to maintain (i) a minimum ratio of Common Equity Tier 1 capital to risk-weighted assets of at least 4.5%, plus the 2.5% capital conservation buffer (7.0% upon full implementation), (ii) a minimum ratio of Tier 1 capital to risk-weighted assets of at least 6.0%, plus the 2.5% capital conservation buffer (8.5% upon full implementation), (iii) a minimum ratio of Total capital (that is, Tier 1 plus Tier 2) to risk-weighted assets of at least 8.0%, plus the 2.5% capital conservation buffer (10.5% upon full implementation) and (iv) a minimum leverage ratio of 4.0%, calculated as the ratio of Tier 1 capital to average quarterly assets. Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth in the table below) of total, Common Equity Tier 1 ("CET1") and Tier 1 capital (as defined in the regulations) to risk weighted assets (as defined), and of Tier 1 capital (as defined) to average assets (as defined). Management believes, as of December 31, 2018 and 2017 , the Company and the Bank meet all capital adequacy requirements to which they are subject, including the capital buffer requirement. As of December 31, 2018 and 2017 , the Bank’s capital ratios exceeded those levels necessary to be categorized as “well capitalized” under the regulatory framework for prompt corrective action. To be categorized as “well capitalized," the Bank must maintain minimum total risk based, CET1, Tier 1 risk based and Tier 1 leverage ratios as set forth in the table. There are no conditions or events since that notification that management believes have changed the Bank’s category. The actual capital amounts and ratios of the Company and Bank as of December 31, 2018 and 2017 , are presented in the following table: Actual Minimum for Capital Adequacy Purposes To Be Well Capitalized Under Prompt Corrective Action Provisions Amount Ratio Amount Ratio Amount Ratio December 31, 2018 Total capital to risk weighted assets: Consolidated $ 1,072,156 12.58 % $ 681,686 8.00 % N/A N/A Bank 1,054,783 12.39 681,004 8.00 $ 851,255 10.00 % Tier 1 capital to risk weighted assets: Consolidated 887,354 10.41 511,264 6.00 N/A N/A Bank 1,009,981 11.86 510,753 6.00 681,004 8.00 Common equity tier 1 to risk weighted assets: Consolidated 856,754 10.05 383,448 4.50 N/A N/A Bank 1,009,981 11.86 383,065 4.50 553,316 6.50 Tier 1 capital to average assets: Consolidated 887,354 9.57 370,727 4.00 N/A N/A Bank 1,009,981 10.91 370,412 4.00 463,015 5.00 December 31, 2017 Total capital to risk weighted assets: Consolidated $ 897,760 12.56 % $ 572,025 8.00 % N/A N/A Bank 867,082 12.15 571,142 8.00 $ 713,928 10.00 % Tier 1 capital to risk weighted assets: Consolidated 718,358 10.05 429,019 6.00 N/A N/A Bank 827,680 11.59 428,357 6.00 571,142 8.00 Common equity tier 1 to risk weighted assets: Consolidated 687,006 9.61 321,764 4.50 N/A N/A Bank 827,680 11.59 321,268 4.50 464,053 6.50 Tier 1 capital to average assets: Consolidated 718,358 8.92 322,124 4.00 N/A N/A Bank 827,680 10.30 321,384 4.00 401,730 5.00 |

Business Combinations | Business Combinations Integrity Bancshares, Inc. On June 1, 2018, the Company acquired 100% of the outstanding stock of Integrity Bancshares, Inc. and its subsidiary, Integrity Bank, SSB, Houston, Texas (Integrity) with four branches located in Houston, TX. The Company issued 2,071,981 shares of Company stock and paid $31,016 in cash for the outstanding shares and options of Integrity common stock. The Company recognized total goodwill of $100,339 , which is calculated as the excess of both the consideration exchanged and liabilities assumed compared to the fair market value of identifiable assets acquired. The fair value of consideration exchanged related to the Company's stock was calculated based upon the closing market price of the Company's stock as of June 1, 2018. The goodwill in this acquisition resulted from a combination of expected synergies and expansion in the Houston market. None of the goodwill recognized is expected to be deductible for income tax purposes. The Company has incurred expenses related to the acquisition of approximately $4,074 and $360 during the years ended December 31, 2018 and 2017, which are included in acquisition expense in the consolidated statements of income. In addition, as of December 31, 2018 , the Company paid offering costs totaling $209 which were recorded as a reduction to stock issuance proceeds through additional paid in capital. Fair values of the assets acquired and liabilities assumed as of the closing date and subsequent measurement period adjustments made during 2018 are as follows: Initially Recorded at Acquisition Date Measurement Period Adjustments Adjusted Values as of December 31, 2018 Assets of acquired bank: Cash and cash equivalents $ 44,723 $ — $ 44,723 Securities available for sale 24,726 (5 ) 24,721 Restricted stock 3,357 — 3,357 Loans 651,722 47 651,769 Premises and equipment 4,800 63 4,863 Goodwill 100,120 219 100,339 Core deposit intangible 7,532 5 7,537 Bank owned life insurance 8,181 — 8,181 Other assets 6,416 (31 ) 6,385 Total assets acquired $ 851,577 $ 298 $ 851,875 Liabilities of acquired bank: Deposits $ 593,078 $ — $ 593,078 FHLB advances 60,000 — 60,000 Other liabilities 10,220 298 10,518 Total liabilities assumed $ 663,298 $ 298 $ 663,596 Common stock issued at $75.90 per share $ 157,263 $ — $ 157,263 Cash paid $ 31,016 $ — $ 31,016 The nature of the measurement period adjustments noted in the table above was a result of information obtained subsequent to our initial reporting of provisional fair values but prior to finalizing our fair values in accordance with ASC 805, Business Combinations . Such information was determined to be a condition in existence as of acquisition date. The income effects resulting from the recorded measurement period adjustments during the period ending December 31, 2018 are immaterial for separate disclosure. Non-credit impaired loans had a fair value of $604,549 at acquisition date and contractual balance of $609,675 . As of acquisition date, the Company expects that an insignificant amount of the contractual balance of these loans will be uncollectible. The difference of $5,126 will be recognized into interest income as an adjustment to yield over the life of the loans. The acquisition is not considered significant to the Company's financial statements and therefore, pro-forma financial data is not included. Carlile Bancshares, Inc. On April 1, 2017, the Company acquired 100% of the outstanding stock of Carlile. This transaction resulted in 24 additional branches in the DFW Metroplex and Austin area as well as 18 branches in Colorado. The Company issued 8,804,699 shares of Company stock and paid $17,773 in cash for the outstanding shares of Carlile common stock. During the fourth quarter of 2017, the Company sold nine of the acquired Colorado branches as part of the Northstar branch integration process (see Note 22 , Branch Sales). The Company has recognized total goodwill of $363,139 which is calculated as the excess of both the consideration exchanged and liabilities assumed compared to the fair market value of identifiable assets acquired. The fair value of the consideration exchanged related to the Company's stock was calculated based upon the closing market price of the Company's stock as of March 31, 2017. The goodwill in this acquisition resulted from a combination of expected synergies and entrance into desirable Texas and Colorado markets. None of the goodwill recognized is expected to be deductible for income tax purposes. The Company has incurred expenses related to the acquisition of approximately $523 , $15,648 and $659 during the years ended December 31, 2018, 2017, and 2016, which are included in noninterest expense in the consolidated statements of income.

Basis of Presentation | Basis of presentation: The accompanying consolidated financial statements include the accounts of IBG, its wholly-owned subsidiaries, the Bank, IBG Adriatica Holdings, Inc. (Adriatica) and Carlile Capital, LLC and the Bank’s wholly-owned subsidiaries, IBG Real Estate Holdings, Inc., IBG Real Estate Holdings II, Inc., IBG Aircraft Company III, Preston Grand, Inc., CFRH II, LLC, McKinney Avenue Holdings, Inc. and its wholly owned subsidiary, McKinney Avenue Holdings SPE 1, Inc. Adriatica, CFRH II, LLC, McKinney Avenue Holdings, Inc. and its subsidiary are currently not active entities. On June 1, 2018, the Company acquired Integrity Bancshares, Inc. (Integrity) and its wholly owned subsidiary, Integrity Bank, SSB, Houston, Texas. Integrity has been merged into the Company and dissolved and Integrity Bank has been merged with the Bank as of acquisition date. See Note 21 , Business Combinations for more details of the Integrity acquisition. All material intercompany transactions and balances have been eliminated in consolidation. In addition, the Company wholly-owns IB Trust I (Trust I), IB Trust II (Trust II), IB Trust III (Trust III), IB Centex Trust I (Centex Trust I), Community Group Statutory Trust I (CGI Trust I), Northstar Statutory Trust II (Northstar Trust II) and Northstar Statutory Trust III (Northstar Trust III). The Trusts were formed to issue trust preferred securities and do not meet the criteria for consolidation (see Note 12 ). |
Segment Reporting | Segment reporting: The Company has one reportable segment. The Company’s chief operating decision-maker uses consolidated results to make operating and strategic decisions. |
Reclassifications | Reclassifications: Certain prior period financial statement amounts have been reclassified to conform to current period presentation. The reclassifications have no effect on net income or stockholders' equity as previously reported. |
Use of estimates | Use of estimates: The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect certain reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Accordingly, actual results could differ from those estimates. The material estimates included in the financial statements relate to the allowance for loan losses, the valuation of goodwill and valuation of assets and liabilities acquired in business combinations. |
Cash and cash equivalents | Cash and cash equivalents: For the purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from banks and federal funds sold. All highly liquid investments with an initial maturity of less than ninety days are considered to be cash equivalents. The Company maintains deposits with other financial institutions in amounts that exceed FDIC insurance coverage. The Company's management monitors the balance in these accounts and periodically assesses the financial condition of the other financial institutions. The Company has not experienced any losses in such accounts and believes it is not exposed to any significant credit risks on cash or cash equivalents. |
Certificates of deposit | Certificates of deposit: Certificates of deposit are FDIC insured deposits in other financial institutions that mature within 18 months and are carried at cost. |
Securities | Securities: Securities classified as available for sale are those debt securities that the Company intends to hold for an indefinite period of time, but not necessarily to maturity. Any decision to sell a security classified as available for sale would be based on various factors, including significant movements in interest rates, changes in the maturity mix of the Company's assets and liabilities, liquidity needs, regulatory capital considerations and other similar factors. Securities available for sale are reported at fair value with unrealized gains or losses reported as a separate component of other comprehensive income, net of tax. The amortization of premiums and accretion of discounts, computed by the interest method over their contractual lives, are recognized in interest income. Realized gains or losses, determined on the basis of the cost of specific securities sold, are included in earnings on the trade date. In estimating other than temporary impairment losses, management considers (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) the intent of the Company to retain its investment and whether it is more likely than not the Company will be required to sell its investment before its anticipated recovery in fair value. When the Company does not intend to sell the security, and it is more likely than not that it will not have to sell the security before recovery of its cost basis, it will recognize the credit component of an other than temporary impairment of a debt security in earnings and the remaining portion in other comprehensive income. |
Loans held for sale | Loans held for sale: The Company originates residential mortgage loans that may subsequently be sold to unaffiliated third parties. The Company elected the fair value option for certain residential mortgage loans held for sale originated after July 1, 2018 in accordance with ASC 825, Financial Instruments. This election allows for a more effective offset of the changes in fair values of the loans and the derivative instruments used to economically hedge them without the burden of complying with the requirements for hedge accounting under ASC 815, Derivatives and Hedging . The Company has not elected the fair value option for other residential mortgage loans held for sale primarily because they are not economically hedged using derivative instruments. Mortgage loans originated and intended for sale not recorded under the fair value option are carried at the lower of aggregate cost or fair value, as determined by aggregate outstanding commitments from investors. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income. All mortgage loans held for sale are sold without servicing rights retained. Gains and losses on sales of loans are recognized in noninterest income at settlement dates and are determined by the difference between the sales proceeds and the carrying value of the loans. |
Acquired loans | Acquired loans: Acquired loans from the transactions accounted for as a business combination include both non-performing loans with evidence of credit deterioration since their origination date and performing loans. The Company is accounting for the non-performing loans acquired in accordance with ASC 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality . The performing loans are being accounted for under ASC 310-20, Nonrefundable Fees and Other Costs , with the related difference in the initial fair value and unpaid principal balance (the discount) recognized as interest income on a level yield basis over the life of the loan. At the date of the acquisition, the acquired loans are recorded at their fair value with no valuation allowance. Purchased credit impaired loans are accounted for individually. The Company estimates the amount and timing of undiscounted expected cash flows for each loan, and the expected cash flows in excess of fair value is recorded as interest income over the remaining life of the loan (accretable yield). The excess of the loan's contractual principal and interest over expected cash flows is not recorded (nonaccretable difference). Over the life of the loan, expected cash flows continue to be estimated. If the expected cash flows decrease, an impairment loss is recorded. If the expected cash flows increase, it is recognized as part of future interest income. |
Loans, net | Loans, net: Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are reported at their outstanding principal balance, net of unearned interest, purchase premiums and discounts, deferred loan fees and an allowance for loan losses. Fees and costs associated with originating loans are generally recognized in the period they are incurred, except in the Houston market, former Grand Bank and Carlile branches, which fees are deferred. The provisions of ASC 310, Receivables , generally provide that such fees and related costs be deferred and recognized over the life of the loan as an adjustment of yield. Management believes that not deferring such amounts and amortizing them over the life of the related loans does not materially affect the financial position or results of operations of the Company. |
Allowance for loan losses | Allowance for loan losses: The allowance for loan losses is maintained at a level considered adequate by management to provide for probable loan losses. The allowance is increased by provisions charged to expense. Loans are charged against the allowance for loan losses when management believes that collectability of the principal is unlikely. Subsequent recoveries, if any, are credited to the allowance. The provision for loan losses is the amount, which, in the judgment of management, is necessary to establish the allowance for loan losses at a level that is adequate to absorb known and inherent risks in the loan portfolio. See Note 6 for further information on the Company's policies and methodology used to estimate the allowance for loan losses. The allowance is derived from the following two components: 1) allowances established on individual impaired loans, which are based on a review of the individual characteristics of each loan, including the customer’s ability to repay the loan, the underlying collateral values and the industry the customer operates and 2) allowances based on actual historical loss experience for the last three years for similar types of loans in the Company’s loan portfolio adjusted for primarily changes in the lending policies and procedures; collection, charge-off and recovery practices; nature and volume of the loan portfolio; change in value of underlying collateral; volume and severity of nonperforming loans; existence and effect of any concentrations of credit and the level of such concentrations and current, national and local economic and business conditions. This second component also includes an unallocated allowance to cover uncertainties that could affect management’s estimate of probable losses. The unallocated allowance reflects the imprecision inherent in the underlying assumptions used in the methodologies for estimating this component. The Company’s management continually evaluates the allowance for loan losses determined from the allowances established on individual loans and the amounts determined from historical loss percentages adjusted for the qualitative factors above. Should any of the factors considered by management change, the Company’s estimate of loan losses could also change and would affect the level of future provision expense. While the calculation of the allowance for loan losses utilizes management’s best judgment and all the information available, the adequacy of the allowance for loan losses is dependent on a variety of factors beyond the Company’s control, including, among other things, the performance of the entire loan portfolio, the economy, changes in interest rates and the view of regulatory authorities towards loan classifications. |
Premises and equipment, net | Premises and equipment, net: Land is carried at cost. Bank premises, furniture and equipment and aircraft are carried at cost, less accumulated depreciation computed principally by the straight-line method over the estimated useful lives of the assets, which range from three to thirty years. Leasehold improvements are carried at cost and are depreciated over the shorter of the estimated useful life or the lease period. |
Long-term assets | Long-term assets: Premises and equipment and other long-term assets are reviewed for impairment when events indicate that their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value. |
Other real estate owned | Other real estate owned: Real estate properties acquired through, or in lieu of, loan foreclosure are initially recorded at fair value less estimated selling costs at the date of foreclosure, establishing a new cost basis. After foreclosure, valuations are periodically performed by management and the real estate is carried at the lower of carrying amount or fair value less cost to sell. Revenue and expenses from operations of other real estate owned and impairment charges on other real estate are included in noninterest expense. Gains and losses on sale of other real estate are included in noninterest income. |
Goodwill and core deposit intangible, net | Goodwill and core deposit intangible, net: Goodwill represents the excess of costs over fair value of net assets of businesses acquired. Goodwill is tested for impairment annually on December 31 or on an interim basis if an event triggering impairment may have occurred. Core deposit intangibles are acquired customer relationships arising from bank acquisitions and are amortized on a straight-line basis over their estimated useful lives of ten years. Core deposit intangibles are tested for impairment whenever events or changes in circumstances indicate the carrying amount of the assets may not be recoverable from future undiscounted cash flows. |
Restricted stock | Restricted stock : The Bank is a member of the FHLB system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB of Dallas and Independent Bankers Financial Corporation stock do not have readily determinable fair values as ownership is restricted and they lack a ready market. As a result, these stocks are carried at cost and evaluated periodically by management for impairment. Both cash and stock dividends are reported as income. |
Bank-owned life insurance | Bank-owned life insurance: Bank-owned life insurance is recorded at the amount that can be realized under the insurance contracts at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement. Changes in the net cash surrender value of the policies, as well as insurance proceeds received are reflected in noninterest income. |
Income taxes | Income taxes: Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities (excluding deferred tax assets and liabilities related to business combinations or components of other comprehensive income). Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. The effect of a change in tax rates on deferred assets and liabilities is recognized in income taxes during the period that includes the enactment date. A valuation allowance, if needed, reduces deferred tax assets to the expected amount more likely than not to be realized. Realization of deferred tax assets is dependent upon the level of historical income, prudent and feasible tax planning strategies, reversals of deferred tax liabilities and estimates of future taxable income. The Company evaluates uncertain tax positions at the end of each reporting period. The Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefit recognized in the financial statements from any such position is measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. For tax positions not meeting the "more likely than not" test, no tax benefit is recorded. Any interest and/or penalties related to income taxes are reported as a component of income tax expense. |
Loan commitments and related financial instruments | Loan commitments and related financial instruments: In the ordinary course of business, the Company has entered into certain off-balance-sheet financial instruments consisting of commitments to extend credit, commercial letters of credit, and standby letters of credit. Such financial instruments are recorded in the financial statements when they are funded or related fees are incurred or received. Management estimates losses on off-balance-sheet financial instruments using the same methodology as for portfolio loans. Estimated losses on off-balance-sheet financial instruments are recorded by charges to the provision for losses and credits to other liabilities in the Company's consolidated balance sheet. There were no estimated losses on off-balance sheet financial instruments as of December 31, 2018 or 2017 . |
Stock based compensation | Stock based compensation: Compensation cost is recognized for restricted stock awards issued to employees based on the market price of the Company's common stock on the grant date. Stock-based compensation expense is generally recognized using the straight-line method over the requisite service period for all awards. The impact of forfeitures of stock-based payment awards on compensation expense is recognized as forfeitures occur. |
Transfers of financial assets | Transfers of financial assets: Transfers of financial assets are accounted for as sales, when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Company, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. |
Advertising costs | Advertising costs: Advertising costs are expensed as incurred. |
Business combinations | Business combinations: The Company applies the acquisition method of accounting for business combinations. Under the acquisition method, the acquiring entity in a business combination recognizes 100% of the assets acquired and liabilities assumed at their acquisition date fair values. Management utilizes valuation techniques appropriate for the asset or liability being measured in determining these fair values. Any excess of the purchase price over amounts allocated to assets acquired, including identifiable intangible assets, and liabilities assumed is recorded as goodwill. Where amounts allocated to assets acquired and liabilities assumed is greater than the purchase price, a bargain purchase gain is recognized. Adjustments identified during the measurement period are recognized in the reporting period in which the adjustment amounts are determined. Acquisition-related costs are expensed as incurred. |
Comprehensive income | Comprehensive income: Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities, such as unrealized gains and losses on available for sale securities, are reported as a separate component of the equity section of the balance sheet, such items, along with net income, are components of comprehensive income. Gains and losses on available for sale securities are reclassified to net income as the gains or losses are realized upon sale of the securities. The credit component of other than temporary impairment charges are reclassified to net income at the time of the charge. |
Fair values of financial instruments | Fair values of financial instruments: Accounting standards define fair value, establish a framework for measuring fair value in U.S. generally accepted accounting principles, and require certain disclosures about fair value measurements (see Note 17 , Fair Value Measurements). In general, fair values of financial instruments are based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon 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. These adjustments may include amounts to reflect counterparty credit quality and the Company's creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. |
Derivative financial instruments | Derivative financial instruments: The Company enters into certain derivative financial instruments: interest rate lock commitments, forward mortgage-backed securities trades and interest rate swaps. These financial instruments are not designated as hedging instruments and are used for asset and liability management related to the Company's mortgage banking activities and commercial customers' financing needs. All derivatives are carried at fair value in either other assets or other liabilities (see Note 18 , Derivative Financial Instruments ) . Through the normal course of business, the Company enters into interest rate lock commitments with consumers to originate mortgage loans at a specified interest rate. 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. During July 2018, the Company began managing the changes in fair value associated with changes in interest rates related to interest rate lock commitments by using forward sold commitments known as forward mortgage-backed securities trades. These instruments are typically entered into at the time the interest rate lock commitment is made. The Company also offers certain derivatives products, primarily interest rate swaps, directly to qualified commercial banking customers to facilitate their risk management strategies. The interest rate swap derivative positions relate to transactions in which the Company enters into an interest rate swap with a customer, while at the same time entering into an offsetting interest rate swap with another financial institution. An interest rate swap transaction allows customers to effectively convert a variable rate loan to a fixed rate. In connection with each swap, the Company agrees to pay interest to the customer on a notional amount at a variable interest rate and receive interest from the customer on a similar notional amount at a fixed interest rate. At the same time, the Company agrees to pay another financial institution the same fixed interest rate on the same notional amount and receive the same variable interest rate on the same notional amount. These products were not significant for disclosure in prior periods. |
Mortgage banking | Mortgage banking: This revenue category reflects the Company's mortgage production revenue, including fees and income derived from mortgages originated with the intent to sell, gains on sales of mortgage loans and t he initial and subsequent changes in the fair value of the mortgage derivatives . Interest earned on mortgage loans is recorded in interest income. The Company has a mortgage warehouse purchase program which provides a mortgage warehouse lending vehicle to third party mortgage bankers across a broad geographic scale. The mortgage loans are underwritten, in part, on approved investor takeout commitments. These loans have a very short duration ranging between 10 days and 15 days . In some cases, loans to larger mortgage originators may be financed for up to 60 days . These loans are reported as commercial loans since the loans are secured by notes receivable, not real estate. |
Revenue recognition | Revenue recognition: The Company adopted Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (Topic 606) as of January 1, 2018 (See Note 2 , Recent Accounting Pronouncements). ASC Topic 606, R evenue from Contracts with Customers , establishes principles for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from the entity's contracts to provide goods or services to customers. The core principle requires an entity to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration that it expects to be entitled to receive in exchange for those goods or services recognized as performance obligations are satisfied. The majority of the Company's revenue-generating transactions are not subject to ASC 606, including revenue generated from financial instruments, such as loans, letters of credit, and investment securities, as well as revenue related to mortgage banking activities, and BOLI, as these activities are subject to other accounting guidance. Descriptions of revenue-generating activities that are within the scope of ASC 606, and are presented in the accompanying Consolidated Statements of Income as components of noninterest income, are as follows: • Service charges on deposit accounts - these represent general service fees for monthly account maintenance and activity- or-transaction-based fees and consist of transaction-based revenue, time-based revenue (service period), item-based revenue or some other individual attribute-based revenue. Revenue is recognized when the performance obligation is completed which is generally monthly for account maintenance services or when a transaction has been completed (such as a wire transfer). Payment for such performance obligations are generally received at the time the performance obligations are satisfied. • Gains/losses on the sale of other real estate owned - generally recognized when the performance obligation is complete which is typically at delivery of control over the property to the buyer at time of each real estate closing. • Other noninterest income - includes the Company's correspondent bank earnings credit, mortgage warehouse purchase program fees, acquired loan recoveries, wealth management referral income, other deposit fees, and merchant interchange income. The majority of these fees in other noninterest income are not subject to the requirements of ASC 606. The wealth management referral fees, other deposit fees and merchant interchange income are in the scope of ASC 606, and payment for such performance obligations are generally received at the time the performance obligations are satisfied. The Company has made no significant judgments in applying the revenue guidance prescribed in ASC 606 that affect the determination of the amount and timing of revenue from the above-described contracts with customers. |
Stock repurchase plan | Share repurchase program: The Company established share repurchase programs in prior years which would allow the Company to purchase its common stock in the open market or in privately negotiated transactions. In general, share repurchase programs allow the Company to proactively manage its capital position and return excess capital to shareholders. On October 24, 2018, the Company announced the reestablishment of its share repurchase program. The program authorizes the purchase by the Company of up to $75,000 of its common stock. The repurchase program is authorized to continue through October 1, 2019. No shares of Company stock were repurchased by the Company under this program during 2018. |
Subsequent events | Subsequent events: Companies are required to evaluate events and transactions that occur after the balance sheet date but before the date the financial statements are issued. They must recognize in the financial statements the effect of all events or transactions that provide additional evidence of conditions that existed at the balance sheet date, including the estimates inherent in the financial statement preparation process. Entities shall not recognize the impact of events or transactions that provide evidence about conditions that did not exist at the balance sheet date but arose after that date. The Company has evaluated subsequent events through the date of filing these financial statements with the SEC and noted no subsequent events requiring financial statement recognition or disclosure, except as disclosed in Note 24 . |
Earnings per share | Earnings per share: Basic earnings per common share are net income divided by the weighted average number of common shares outstanding during the period. The unvested share-based payment awards that contain rights to non forfeitable dividends are considered participating securities for this calculation. Diluted earnings per common share include the dilutive effect of additional potential common shares issuable under stock warrants. The participating nonvested common stock was not included in dilutive shares as it was anti-dilutive for the years ended December 31, 2018 and 2017 . Proceeds from the assumed exercise of dilutive stock warrants are assumed to be used to repurchase common stock at the average market price. No stock warrants remain outstanding as of December 31, 2018. |
Recent accounting pronouncements | Recent Accounting Pronouncements Adoption of new accounting standards ASU 2014-09, Revenue from Contracts with Customers (Topic 606), ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date. ASU 2014-09 amends existing guidance related to revenue from contracts with customers. The amendments state that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 affects entities that enter into contracts with customers to transfer goods or services or enter into contracts for the transfer of nonfinancial assets, unless those contracts are within the scope of other standards. The Company's revenue consists of net interest income on financial assets and financial liabilities, which is explicitly excluded from the scope of ASU 2014-9, and non-interest income. The Company adopted ASU 2014-09 in the first quarter of 2018 using the modified retrospective approach effective on January 1, 2018 to all existing contracts with customers covered under the scope of the standard. The Company did not have an aggregate effect of modification resulting from the adoption of ASU 2014-09, and no financial statement line items were affected by this change in accounting standard. The newly applicable revenue disclosures have been included in the footnotes to these financial statements (see Note 1, Summary of Significant Accounting Policies). ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. This ASU required that all equity investments be measured at fair value with changes in the fair value recognized through net income (other than those accounted for under the equity method of accounting or those that result in consolidation of the investee). This ASU also required that an entity 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. Additionally, this ASU required that public business entities base their fair value disclosures for financial instruments that are not measured at fair value in the financial statements on the exit price notion. The Company adopted ASU 2016-01 in the first quarter of 2018, and have estimated fair values of loans held for investment for the 2018 period on cash flows, adjusted for credit and prepayments, discounted using current market yields (see Note 17, Fair Value Measurements). The adoption of this ASU did not have a material impact on the Company’s financial statements. ASU 2016-15, Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash Payments. This ASU was intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows, including debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims and distributions received from equity method investments. ASU 2016-15 became effective for the Company on January 1, 2018 and did not have a significant impact on its financial statements. ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220) - Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The amendments in this update allow reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act (TCJA) which was signed into law on December 22, 2017. The Company elected to early adopt ASU 2018-02 in the first quarter of 2018 and apply the guidance to the beginning of the period, effective January 1, 2018 . The impact of adopting the amendment resulted in a cumulative effect adjustment to the consolidated balance sheet as of January 1, 2018 to reclassify approximately $233 of tax expense from accumulated other comprehensive loss to retained earnings as reflected in the accompanying Consolidated Statements of Changes in Stockholders' Equity. Newly issued but not yet effective accounting standards ASU 2016-02, Leases (Topic 842). This ASU will, among other things, require lessees to recognize a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-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. Under this guidance, lessor accounting is largely unchanged. This ASU is effective for annual and interim periods for the Company on January 1, 2019. The Company will adopt the standard by applying the alternative transition method whereby comparative periods will not be restated, and any cumulative effect adjustment to the opening balance of retained earnings would be recognized as of January 1, 2019. The impact to retained earnings is expected to be immaterial. The Company also expects to elect the ASU’s package of three practical expedients, which allows the Company to forego a reassessment of (i) whether any expired or existing contracts are or contain leases, (ii) the lease classification for any expired or existing leases and (iii) the initial direct costs for any existing leases. The Company also does not expect to apply the recognition requirements of the ASU to any short-term leases (as defined by related accounting guidance) and expects to account for lease and non-lease components separately because such amounts are readily determinable under most lease contracts and because we expect this election will result in a lower impact on our balance sheet. The Company has implemented a lease management system to assist in centralizing, maintaining and accounting for all leases and is finalizing its evaluation of the ASU on its financial statements and disclosures, as well as any additional changes to processes and internal controls to ensure we meet the ASU’s reporting and disclosure requirements. The Company currently expects to recognize right-of-use assets and related lease liabilities totaling approximately $26,800 and $21,900 , respectively. The adoption of this ASU is not expected to have a significant impact on the Company’s consolidated statement of income. Presentation of leases within the consolidated statements of income and consolidated statements of cash flows will be generally consistent with the current lease accounting guidance. ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This ASU removes the thresholds that companies apply to measure credit losses on financial instruments measured at amortized cost, such as loans, receivables and held-to-maturity debt securities. Under current US GAAP, companies generally recognize credit losses when it is probable that the loss has been incurred. This revised guidance will remove all recognition thresholds and will require companies to recognize an allowance for lifetime expected credit losses. Credit losses will be immediately recognized through net income; the amount recognized will be based on the current estimate of contractual cash flows not expected to be collected over the financial asset’s contractual term. ASU 2016-13 also amends the credit loss measurement guidance for available for sale debt securities. This ASU will be effective for the Company on January 1, 2020. The Company is currently evaluating the potential impact of ASU 2016-13 on its financial statements and has formed a cross-functional working group, under the direction of executive management including the Chief Financial Officer and Chief Risk Officer. The working group is comprised of individuals from various functional areas including credit, risk management, accounting and information technology, among others. The Company is currently working through its implementation plan which includes such things as assessment and documentation of processes, internal controls and data sources; model development and documentation; and system configuration. The Company is also in the process of implementing a third-party vendor solution to assist in the application of the ASU 2016-13. The adoption of ASU 2016-13 could result in an increase in the allowance for loan losses as a result of changing from an “incurred loss” model, which encompasses allowances for current known and inherent losses within the portfolio, to an “expected loss” model, which encompasses allowances for losses expected to be incurred over the life of the portfolio. Furthermore, this ASU will necessitate that the Company establish an allowance for expected credit losses for certain debt securities and other financial assets. While the Company is currently unable to reasonably estimate the impact of adopting ASU 2016-13, the Company expects that the impact of adoption will be significantly influenced by the composition, characteristics and quality of our loan and securities portfolios as well as the prevailing economic conditions and forecasts as of the adoption date. ASU 2017-04, Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment. This ASU simplifies the accounting for goodwill impairment for all entities by requiring impairment charges to be based on the first step in today’s two-step impairment test. Under the new guidance, if a reporting unit’s carrying amount exceeds its fair value, an entity will record an impairment charge based on that difference. The impairment charge will be limited to the amount of goodwill allocated to that reporting unit. The standard eliminates today’s requirement to calculate a goodwill impairment charge using Step 2, which requires an entity to calculate any impairment charge by comparing the implied fair value of goodwill with its carrying amount. ASU 2017-04 will be effective for the Company on January 1, 2020, with earlier adoption permitted and is not expected to have a significant impact on its financial statements. ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities . This ASU requires certain premiums on callable debt securities to be amortized to the earliest call date. The amortization period for callable debt securities purchased at a discount will not be impacted. Under current GAAP, premiums on callable debt securities are generally amortized over the contractual life of the security. ASU 2017-08 will be effective for the Company on January 1, 2019 and, upon adoption, the Company expects to recognize a cumulative effect adjustment reducing retained earnings by approximately $880 , but otherwise is not expected to have a significant impact to the Company's consolidated financial statements and disclosures. ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. This ASU refines and expand hedge accounting for both financial and commodity risks. Its provisions create more transparency around how economic results are presented, both on the face of the financial statements and in the footnotes. It also makes certain targeted improvements to simplify the application of hedge accounting guidance. ASU 2017-02 will be effective for the Company on January 1, 2019. The adoption of this ASC is not expected to have a significant impact on the Company's consolidated financial statements and disclosures. ASU 2018-07, Improvements to Nonemployee Share-Based Payment Accounting . This ASU aligns much of the guidance on measuring and classifying nonemployee awards with that of awards to employees. The guidance applies to nonemployee awards issued in exchange for goods or services used or consumed in an entity’s own operations and to awards granted by an investor to employees and nonemployees of an equity method investee for goods or services used or consumed in the investee’s operations. There are no new disclosure requirements. This ASU will be effective for the Company on January 1, 2019. The adoption of this ASU is not expected to have a significant impact on the Company’s financial statements and disclosures. ASU 2018-13, Fair Value Measurement (Topic 820) - Changes to the Disclosure Requirements for Fair Value Measurement . This ASU modifies the disclosure requirements on fair value measurements by requiring that Level 3 fair value disclosures include the range and weighted average of significant unobservable inputs used to develop those fair value measurements. For certain unobservable inputs, an entity may disclose other quantitative information in lieu of the weighted average if the entity determines that other quantitative information would be a more reasonable and rational method to reflect the distribution of unobservable inputs used to develop Level 3 fair value measurements. ASU 2018-13 will be effective for the Company on January 1, 2020, with early adoption permitted, and is not expected to have a significant impact on its financial statements and disclosures. ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) - Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. This ASU aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). The accounting for the service element of a hosting arrangement that is a service contract is not affected by these amendments. This ASU will be effective for the Company on January 1, 2020, with early adoption permitted, and is not expected to have a significant impact on its financial statements and disclosures. |
Nonaccrual loan and lease status | The accrual of interest is discontinued on a loan when management believes, after considering collection efforts and other factors that the borrower's financial condition, is such that collection of interest is doubtful. All interest accrued but not collected for loans that are placed on nonaccrual status or charged-off is reversed against interest income. Cash collections on nonaccrual loans are generally credited to the loan receivable balance, and no interest income is recognized on those loans until the principal balance has been collected. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. |
Impaired loan and lease receivable | Impaired loans are those loans where it is probable that all amounts due according to contractual terms of the loan agreement will not be collected. The Company has identified these loans through its normal loan review procedures. Impaired loans are measured based on 1) the present value of expected future cash flows discounted at the loans effective interest rate; 2) the loan's observable market price; or 3) the fair value of collateral if the loan is collateral dependent. Substantially all of the Company’s impaired loans are measured at the fair value of the collateral. In limited cases, the Company may use other methods to determine the level of impairment of a loan if such loan is not collateral dependent. |
Loan charge off amounts | The Company will charge off that portion of any loan which management considers a loss. Commercial and real estate loans are generally considered for charge-off when exposure beyond collateral coverage is apparent and when no further collection of the loss portion is anticipated based on the borrower’s financial condition. |
Trouble debt restructuring | The restructuring of a loan is considered a “troubled debt restructuring” if both 1) the borrower is experiencing financial difficulties and 2) the creditor has granted a concession. Concessions may include interest rate reductions or below market interest rates, principal forgiveness, extending amortization and other actions intended to minimize potential losses. A “troubled debt restructured” loan is identified as impaired and measured for credit impairment as of each reporting period in accordance with the guidance in ASC 310-10-35. |
Loans past due | Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. |
Fair value measurements | Securities classified as available for sale are reported at fair value utilizing Level 1 and Level 2 inputs. Securities are classified within Level 1 when quoted market prices are available in an active market. Inputs include securities that have quoted prices in active markets for identical assets. For securities utilizing Level 2 inputs, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury and other yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the security’s terms and conditions, among other things. Certain mortgage loans held for sale are measured at fair value on a recurring basis due to the Company's election to adopt fair value accounting treatment for those loans originated after July 1, 2018 for which the Company has entered into certain derivative financial instruments as part of its mortgage banking and related risk management activities. These instruments include interest rate lock commitments and mandatory forward commitments to sell these loans to investors known as forward mortgage-backed securities trades. Such mortgage loans held for sale, which are sold on a servicing released basis, are valued using a market approach by utilizing either: (i) the fair value of 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 to 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. For mortgage loans held for sale for which the fair value option was elected, the earned current contractual interest payment is recognized in interest income, loan origination costs and fees on fair value option loans are recognized in earnings as incurred and not deferred. The Company has no continuing involvement in any residential mortgage loans sold. The estimated fair values of interest rate lock commitments utilize 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 interest rate lock commitments 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, as the valuations are based on observable market inputs. Forward mortgage-backed securities trades are exchange-traded or traded within highly active dealer markets. In order to determine the fair value of these instruments, the Company utilized the exchange price or dealer market price for the particular derivative contract; therefore these contracts are classified as Level 2. The estimated fair values are subject to change primarily due to changes in interest rates. The Company also enters into certain interest rate derivative positions that are not designated as hedging instruments. The estimated fair value of these commercial loan interest rate swaps are obtained from a pricing service that provides the swaps' unwind value (Level 2 inputs). See Note 18 , Derivative Financial Instruments, for more information. Assets and Liabilities Measured on a Nonrecurring Basis In accordance with ASC Topic 820, certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the assets and liabilities 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). Impaired loans (loans which are not expected to repay all principal and interest amounts due in accordance with the original contractual terms) are measured at an observable market price (if available) or at the fair value of the loan’s collateral (if collateral dependent). Fair value of the loan’s collateral is determined by appraisals or independent valuation which is then adjusted for the estimated costs related to liquidation of the collateral. Management’s ongoing review of appraisal information may result in additional discounts or adjustments to valuation based upon more recent market sales activity or more current appraisal information derived from properties of similar type and/or locale. Therefore, the Company has categorized its impaired loans as Level 3. Other real estate is measured at fair value on a nonrecurring basis (upon initial recognition or subsequent impairment). Other real estate owned is classified within Level 3 of the valuation hierarchy. When transferred from the loan portfolio, other real estate owned is adjusted to fair value less estimated selling costs and is subsequently carried at the lower of carrying value or fair value less estimated selling costs. The fair value is determined using an external appraisal process, discounted based on internal criteria. Therefore, the Company has categorized its other real estate as Level 3. In addition, mortgage loans held for sale not recorded under the fair value option are required to be measured at the lower of cost or fair value. The fair value of these loans is based upon binding quotes or bids from third party investors. The methods and assumptions used by the Company in estimating fair values of financial instruments as disclosed herein in accordance with ASC Topic 825, Financial Instruments , as amended by ASU 2016-01 requiring public entities to use the exit price notion effective January 1, 2018, other than for those measured at fair value on a recurring and nonrecurring basis discussed above, are as follows: Cash and cash equivalents: The carrying amounts of cash and cash equivalents approximate their fair value. Certificates of deposit held in other banks: The fair value of certificates of deposit held in other banks is based upon current market rates. Loans held for sale, at cost: The fair value of loans held for sale is determined based upon commitments on hand from investors. Loans: Pursuant to the adoption of ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, for loan values reported for the 2018 period, a discounted cash flow model is used to estimate the fair value of the loans. The discounted cash flow approach models the credit losses directly in the projected cash flows, applying various assumptions regarding credit, interest, and prepayment risks for the loans based on loan types, payment types and fixed or variable classifications. Loans reported prior to 2018 were valued as follows: For variable-rate loans that reprice frequently and have no significant changes in credit risk, fair values are based on carrying values. Fair values for certain mortgage loans (for example, one-to-four family residential), commercial real estate and commercial loans are estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. Federal Home Loan Bank of Dallas and other restricted stock: The carrying value of restricted securities such as stock in the Federal Home Loan Bank of Dallas and Independent Bankers Financial Corporation approximates fair value. Deposits: The fair values disclosed for demand deposits are, by definition, equal to the amount payable on demand at the reporting date (that is their carrying amounts). The carrying amounts of variable-rate certificates of deposit (CDs) approximate their fair values at the reporting date. Fair values for fixed-rate CDs are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits. Federal Home Loan Bank advances, line of credit and federal funds purchased: The fair value of advances maturing within 90 days approximates carrying value. Fair value of other advances is based on the Company’s current borrowing rate for similar arrangements. Other borrowings: The carrying value of repurchase agreements approximates fair value due to the short term nature. The fair value of private subordinated debentures are based upon prevailing rates on similar debt in the market place. The subordinated debentures that are publicly traded are valued based on indicative bid prices based upon market pricing observations in the current market. Junior subordinated debentures: The fair value of junior subordinated debentures is estimated using discounted cash flow analyses based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements. Accrued interest: The carrying amounts of accrued interest approximate their fair values. Off-balance sheet instruments: Fair values for off-balance sheet, credit-related financial instruments are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties' credit standing. The fair value of commitments is not material. The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. In estimating fair value, the Company utilizes valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. Such valuation techniques are consistently applied. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. ASC Topic 820, Fair Value Measurements and Disclosures , 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 might 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 (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means. Level 3 Inputs – Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities. The Company elected the fair value option for certain residential mortgage loans held for sale originated after July 1, 2018 in accordance with ASC 825, Financial Instruments. This election allows for a more effective offset of the changes in fair values of the loans and the derivative instruments used to economically hedge them without the burden of complying with the requirements for hedge accounting under ASC 815, Derivatives and Hedging . The Company has not elected the fair value option for other residential mortgage loans held for sale primarily because they are not economically hedged using derivative instruments. See below and Note 18 , Derivative Financial Instruments, for additional information. |
