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, doing business as Independent Financial (Bank) (collectively known as the Company), provides a full range of banking services to individual and corporate customers in the 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, and 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 and all other entities in which IBG has controlling financial interest. All material intercompany transactions and balances have been eliminated in consolidation. In addition, the Company wholly-owns nine statutory business trusts that were formed for the purpose of issuing trust preferred securities and do not meet the criteria for consolidation (See Note 11. Junior Subordinated Debentures ). 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. 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 and disclosure 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 GAAP 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 credit 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. Restricted cash: The Company maintains cash collateral balances which have been pledged to derivative counterparties and are legally restricted as to use. 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: Debt securities that management has the positive intent and ability to hold to maturity are classified as held to maturity and recorded at amortized cost. Debt securities that the Company intends to hold for an indefinite period of time, but not necessarily to maturity are classified as available for sale. 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. 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. The amortization of premiums and accretion of discounts, computed by the interest method generally over their contractual lives, are recognized in interest income. Premiums on callable securities are amortized to their earliest call date. Realized gains or losses, determined on the basis of the cost of specific securities sold, are included in earnings on the trade date. As of December 31, 2021 and 2020, all of the Company's securities were classified as available 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 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. Loans held for investment: 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 or costs and an allowance for credit losses. Loan origination fees, net of direct origination costs, are deferred and recognized as an adjustment to the related loan yield using the effective interest method without anticipating prepayments. Further information regarding the Company's accounting policies related to past due loans, non-accrual loans, collateral dependent loans and troubled-debt restructurings is presented in Note 5. Loans, Net and Allowance for Credit Losses on Loans . Acquired loans: In accordance with ASC 326, Measurement of Credit Losses on Financial Instruments , loans acquired in connection with a business combination are recorded at their acquisition-date fair value. The allowance for credit losses related to the acquired loan portfolio is not carried over. Acquired loans are classified into two categories based on the credit risk characteristics of the underlying borrowers as either purchased credit deteriorated (PCD) loans, or loans with no evidence of credit deterioration (non-PCD). PCD loans are defined as a loan or pool of loans that have experienced more-than-insignificant credit deterioration since the origination date. For PCD loans, an initial allowance is established on the acquisition date using the same methodology as other loans held for investment and combined with the fair value of the loan to arrive at acquisition date amortized cost. Accordingly, no provision for credit losses is recognized on PCD loans at the acquisition date. Subsequent to the acquisition date, changes to the allowance are recognized in the provision for credit losses. Non-PCD loans are pooled into segments together with originated held for investment loans that share similar risk characteristics and have an allowance established on the acquisition date, which is recognized in the current period provision for credit losses. Determining the fair value of the acquired loans involves estimating the principal and interest payment cash flows expected to be collected on the loans and discounting those cash flows at a market rate of interest. For PCD loans, the non-credit discount or premium is allocated to individual loans as determined by the difference between the loan’s unpaid principal balance and amortized cost basis. The non-credit premium or discount is recognized into interest income on a level yield basis over the remaining expected life of the loan. For non-PCD loans, the fair value discount or premium is allocated to individual loans and recognized into interest income on a level yield basis over the remaining expected life of the loan. Prior to January 1, 2021 as further discussed in Note 2. Recent Accounting Standards , loans acquired in a business combination that had evidence of credit impairment and for which it was probable, at acquisition, that the Company would be unable to collect all contractually required payments receivable were considered PCI. PCI loans were accounted for individually or aggregated into pools of loans based on common risk characteristics such as credit grade, loan type, and date of origination. Allowance for credit losses: Refer to Note 2. Recent Accounting Standards for discussion of the change in methodology used to calculate the allowance for credit losses as a result of adopting of ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), effective January 1, 2021. Allowance for credit losses - loans : In accordance with ASC 326, Measurement of Credit Losses on Financial Instruments , the allowance for credit losses on loans is a valuation account that is deducted from the amortized cost basis of loans to present management's best estimate of the net amount expected to be collected. Loans, or portions thereof, are charged-off against the allowance for credit losses when management believes that collectability of the principal is unlikely. Subsequent recoveries, if any, are credited to the allowance. The allowance is increased (decreased) by provisions (or reversals of) reported in the income statement as a component of provision for credit losses. Management has made the accounting policy election to exclude accrued interest receivable on loans from the estimate of credit losses and reports accrued interest separately in other assets in the consolidated balance sheets. Further information regarding Company policies and methodology used to estimate the allowance for credit losses on loans is presented in Note 5. Loans, Net and Allowance for Credit Losses on Loans . Prior to 2021, as further discussed in Note 2. Recent Accounting Standards , the allowance for credit losses on loans was a valuation account established through a provision for credit losses charged to expense, which represented management’s best estimate of inherent losses that had been incurred within the existing portfolio of loans. The allowance for credit losses on loans included allowance allocations calculated in accordance with ASC Topic 310, Receivables , and allowance allocations calculated in accordance with ASC Topic 450, Contingencies . Allowance for credit losses - available for sale securities: For available for sale securities in an unrealized loss position, the Company first assesses whether it intends to sell or it is more-likely-than-not that it will be required to sell the securities before recovery of the amortized cost basis. If either of these criteria is met, the securities amortized cost basis is written down to fair value as a current period expense. If either of the above criteria is not met, the Company evaluates whether the decline in fair value is the result of credit losses or other factors. In making this assessment, management may consider various factors including the extent to which fair value is less than amortized cost, performance of any underlying collateral and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected are compared to the amortized cost basis of the security and any excess of the amortized cost basis over the present value of expected cash flows is recorded as an allowance for credit loss, limited to the amount by which the fair value is less than the amortized cost basis. Any impairment not recorded through an allowance for credit loss is recognized in other comprehensive income as a non credit-related impairment. Changes in the allowance for credit losses are recorded as provision for (or reversal of) credit losses. Available for sale securities are charged-off against the allowance or, in the absence of any allowance, written down through income when deemed uncollectible by management or when either of the aforementioned criteria regarding intent or requirement to sell is met. Allowance for credit losses - held to maturity securities : The allowance for credit losses on held to maturity securities is a valuation account that is deducted from the amortized cost basis of held to maturity securities to present management's best estimate of the net amount expected to be collected. Held to maturity securities are charged-off against the allowance when deemed uncollectible by management. Adjustments to the allowance are reported in the income statement as a component of provision for credit losses. Management measures expected credit losses on held to maturity securities on a collective basis by major security type with each type sharing similar risk characteristics and considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. Management has made the accounting policy election to exclude accrued interest receivable on available for sale and held to maturity securities from the estimate of credit losses and report accrued interest separately in other assets in the consolidated balance sheet. Allowance for credit losses on off-balance sheet credit exposures: The allowance for credit losses on off-balance sheet credit exposures is a liability account, calculated in accordance with ASC 326, representing expected credit losses over the contractual period for which the Company is exposed to credit risk resulting from a contractual obligation to extend credit. No allowance is recognized if we have the unconditional right to cancel the obligation. The allowance is reported as a component of other liabilities in the consolidated balance sheets. Adjustments to the allowance are reported in the income statement as a component of provision for credit losses. Further information regarding Company policies and methodology used to estimate the allowance for credit losses on off-balance sheet credit exposures is presented in Note 14. Off-Balance Sheet Arrangements, Commitments and Contingencies . 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 Leasehold improvements are carried at cost and are depreciated over the shorter of the estimated useful life or the lease period. Software: Costs incurred in connection with development or purchase of internal use software and cloud computing arrangements, including in-substance software licenses, are capitalized. Amortization is computed on a straight-line basis over the estimated useful life of the asset, which generally ranges from one Leases: The Company's leases are accounted for under ASC Topic 842, Leases . For operating leases with a term greater than one year, the Company recognizes operating right-of-use (ROU) lease assets and operating lease liabilities, which are recorded in other assets and other liabilities, respectively, in the consolidated balance sheets. The Company determines if an arrangement is a lease at inception. Operating ROU lease assets and related liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate referenced to the Federal Home Loan Bank Secure Connect advance rates for borrowings of similar terms in determining the present value of lease payments. The operating ROU lease asset also includes any lease pre-payments made and excludes lease incentives. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which the Company has elected to account for separately as the non-lease component amounts are readily determinable under most leases. 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 other intangible assets, 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. On January 1, 2020, ASU 2017-04, Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment became effective for the Company as further explained in Note 2. Recent Accounting Standards . Under the guidance, if a reporting unit’s carrying amount exceeds its fair value, an entity will record an impairment charge based on that difference. As of December 31, 2021, the fair value of the Company’s stock price and calculated market capitalization exceeded its carrying value. Core deposit intangibles and other acquired customer relationship intangibles arising from bank acquisitions are amortized on a straight-line basis over their estimated useful lives of ten years and thirteen years, respectively. Other intangible assets 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 other restricted 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. Stock based compensation: Compensation cost is recognized for restricted stock awards/stock units 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 time-based awards. Compensation expense for performance stock units is recognized over the service period of the award based upon the probable number of units expected to vest. 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. For cash flow hedges, gains and losses on the derivative(s) are recorded in accumulated other comprehensive income and subsequently reclassified into interest income in the same period that the hedged transaction affects earnings. Fair values of financial instruments: Accounting standards define fair value, establish a framework for measuring fair value in GAAP, 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. The accounting for changes in fair value depends on the intended use of the derivative. Changes in fair value of derivatives designated in a qualifying hedge relationship are recorded in accumulated other comprehensive income. Changes in fair value of derivatives not designated in a qualifying hedge relationship are recognized directly in earnings. All derivatives are carried at fair value in either other assets or other liabilities. See Note 18. Derivative Financial Instruments for further information regarding Company policy. 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 the initial and subsequent changes in the fair value of the mortgage derivatives. Interest earned on mortgage loans is recorded in interest income. Revenue recognition: ASC Topic 606, R evenue from Contracts with Customers (ASC 606) , 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. • Investment management and trust - includes income related to providing investment management and trust services to customers under investment management and trust contracts. Also included are fees received from a third party broker-dealer as part of a revenue-sharing agreement for fees earned from customers that are referred to a third party. The investment management fees and referral fees are billed and paid on a quarterly basis and recognized ratably throughout the quarter as performance obligations are satisfied. • Mortgage warehouse purchase program fees - includes fees for the administration and funding of mortgage loans, as well as renewal and application fees received from mortgage originator customers through our mortgage warehouse purchase program. Revenue related to the warehouse program is recognized when the related loan interest is paid off or upon renewal or application. • 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, acquired loan recoveries, 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 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. 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 Securities and Exchange Commission (SEC) and noted no subsequent events requiring financial statement recognition or disclosure, except as disclosed in Note 22. Subsequent Events . Earnings per share: Basic earnings per common share is calculated as net income available to common shareholders divided by the weighted average number of common shares outstanding during the period. The unvested share-based payment awards that contain rights to nonforfeitable dividends are considered participating securities for this calculation. Diluted earnings per common share includes the dilutive effect of additional potential common shares issuable under participating nonvested restricted stock awards as well as performance stock units (PSUs). The participating nonvested restricted stock awards were not included in dilutive shares as |

Recent Accounting Pronouncements | Recent Accounting Standards Adoption of new accounting standards ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) (ASC 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13). On January 1, 2020, ASU 2016-13, as amended, became effective for the Company. ASU 2016-13 replaces the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (CECL) methodology. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including loan receivables and held to maturity debt securities. It also applies to off-balance sheet credit exposures not accounted for as insurance (loan commitments, standby letters of credit, financial guarantees, and other similar instruments). The CECL model requires the measurement of all expected credit losses on applicable financial assets based on historical experience, current conditions, and reasonable and supportable forecasts. In addition, ASU 2016-13 includes certain changes to the accounting for available for sale securities such as requiring credit-related impairments to be recognized as an allowance for credit losses rather than as a direct write-down of the securities amortized cost basis when management does not intend to sell or believes that it is more likely than not they will be required to sell securities prior to recovery of the securities amortized cost basis. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) was signed by the President of the United States that included an option for financial institutions to delay the implementation of ASU 2016-13 until the earlier of the termination date of the national emergency declaration by the President or December 31, 2020. On December 27, 2020, the Consolidated Appropriations Act, 2021 (Act 2021), was signed into law which further extended the implementation date of CECL to the earlier of the first day of the entity’s fiscal year that begins after the date on which the COVID-19 national emergency terminates or January 1, 2022. Under the CARES Act provision, the Company elected to delay implementation of ASU 2016-13 and calculated and recorded its provision for credit losses under the incurred loss model that existed prior to ASU 2016-13 for the year ended December 31, 2020. With regard to Act 2021 amendments, the SEC staff indicated it would not object to a registrant early adopting on December 31, 2020, retrospective to January 1, 2020, or January 1, 2021, effective as of January 1, 2021. Under this guidance, the Company elected to adopt ASU 2016-13 with an effective implementation date of January 1, 2021. The Company adopted ASU 2016-13 using the modified retrospective method for all financial assets measured at amortized cost and off-balance sheet credit exposures. As a result of this adoption, the Company recognized a cumulative effect reduction to retained earnings totaling $53,880, net of a recorded deferred tax asset of $15,113, and reclassed $13,035 of allowance for credit loss related to financial assets purchased with credit deterioration (PCD) that were previously classified as purchased credit impaired (PCI) and accounted for under ASC 310-30 as discussed below. Results for periods beginning after January 1, 2021 are presented in accordance with ASU 2016-13 while prior period amounts continue to be reported in accordance with previously applicable GAAP. The Company adopted ASU 2016-13 using the prospective transition approach for PCD assets. In accordance with the standard, management did not reassess whether PCI assets met the criteria of PCD assets as of the date of adoption. On January 1, 2021, the amortized cost basis of the PCD assets were adjusted to reflect the addition of the allowance for credit losses. The remaining noncredit discount (based on the adjusted amortized cost basis) was accreted into interest income at the effective interest rate as of January 1, 2021. The following table illustrates the impact of ASU 2016-13 on the allowances for credit losses as of January 1, 2021, the date of adoption: January 1, 2021 Pre-Adoption Allowance Impact of Adoption Initial allowance on loans purchased with credit deterioration Post-Adoption Allowance Assets: Allowance for credit losses on Loans: Commercial $ 27,311 $ 12,775 $ 4,328 $ 44,414 Commercial real estate 36,698 29,108 7,640 73,446 Commercial construction, land and land development 13,425 22,008 927 36,360 Residential real estate 6,786 (2,255) 140 4,671 Single-family interim construction 2,156 7,179 — 9,335 Agricultural 337 (178) — 159 Consumer 684 (334) — 350 Unallocated 423 (423) — — $ 87,820 $ 67,880 $ 13,035 $ 168,735 Liabilities: Allowance for credit losses on off-balance sheet credit exposures $ — $ 1,113 $ — $ 1,113 ASU 2020-08, Codification Improvements to Subtopic 310-20, Receivables - Nonrefundable Fees and Other Costs . ASU 2020-08 clarifies the accounting for the amortization of purchase premiums for callable debt securities with multiple call dates. ASU 2020-8 was effective for the Company on January 1, 2021 and did not have a significant impact on our financial statements. ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting and subsequent clarifying update ASU 2021-01 Reference Rate Reform (Topic 848); Scope. ASU 2020-04 provides temporary optional guidance to ease the potential burden in accounting for reference rate reform. The new guidance provides optional expedients and exceptions for applying GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. The ASU is intended to help stakeholders during the global market-wide reference rate transition period. ASU 2021-01 clarifies that certain optional expedients and exceptions in ASC 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. ASU 2021-01 also amends the expedients and exceptions in ASC 848 to capture the incremental consequences of the scope clarification and to tailor the existing guidance to derivative instruments affected by the discounting transition. These ASUs were effective upon issuance and generally can be applied through December 31, 2022. The adoption of these ASUs did not significantly impact our financial statements or disclosures. ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The guidance issued in this update simplified the accounting for income taxes by eliminating certain exceptions to the guidance in ASC 740 related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition for deferred tax liabilities for outside basis differences. ASU 2019-12 also simplified aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarified the accounting for transactions that result in a step-up in the tax basis of goodwill. ASU 2019-12 was effective for the Company on January 1, 2021 and did not have a significant impact on our financial statements. 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 became effective for the Company on January 1, 2020 and did not have a significant impact on its financial statements and disclosures. ASU 2018-13, Fair Value Measurement (Topic 820) - Changes to the Disclosure Requirements for Fair Value Measurement. This ASU modified 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 became effective for the Company on January 1, 2020 and did not have a significant impact on its financial statements and disclosures. 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 is not impacted. Under current GAAP, premiums on callable debt securities are generally amortized over the contractual life of the security. ASU 2017-08 became effective for the Company on January 1, 2019 and, upon adoption, the Company recognized a cumulative effect adjustment reducing retained earnings by $856, net of the deferred tax impact, but otherwise did not have a significant impact to the Company's consolidated financial statements and disclosures. ASU 2017-04, Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment. This ASU simplified 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 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 eliminated the prior requirement to calculate a goodwill impairment charge using Step 2, which required an entity to calculate any impairment charge by comparing the implied fair value of goodwill with its carrying amount. ASU 2017-04 became effective for the Company on January 1, 2020, and did not have a significant impact on its financial statements. ASU 2016-02, Leases (Topic 842) |

This conclusion is based on management's analysis of the underlying risk characteristics, including credit ratings, and other qualitative factors for each security type in our portfolio. The unrealized losses are generally due to increases in market interest rates. Furthermore, the Company has the intent to hold these securities until maturity or a forecasted recovery, and it is more likely than not that the Company will not have to sell the securities before the recovery of their cost basis. As such, there is no allowance for credit losses on available for sale securities recognized as of December 31, 2021 . |

(2) Excludes accrued interest receivable of $41,051 and $54,328 at December 31, 2021 and December 31, 2020, respectively, that is recorded in other assets on the accompanying consolidated balance sheets. 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 nonperforming 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. Our commercial portfolio also includes Shared National Credits (SNC). SNCs are loan participations purchased from upstream financial organizations that are typically larger in size than the Company's originated loan portfolio. In some instances, the Company participates as the lead, originating bank. SNC loans are originated in the normal course of business and are subject to the same underwriting standards as our portfolio loans. SNCs are subject to regular monitoring of performance and credit quality. At December 31, 2021 and 2020, the SNC portfolio totaled $294,351 and $187,589, respectively. 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, 2021 and 2020, there were approximately $342,776 and $205,496 of energy-related loans outstanding, respectively. With the passage of the CARES Act Paycheck Protection Program (PPP) in 2020, administered by the Small Business Administration (SBA), the Company participated by originating loans to its customers through the program. PPP loans have terms of two The Company has a mortgage warehouse purchase program providing mortgage inventory financing for residential mortgage loans originated by mortgage banker clients across a broad geographic scale. Proceeds from the sale of mortgages is the primary source of repayment for warehouse inventory financing via approved investor takeout commitments. These loans typically have a very short duration ranging between a few days to 15 days. In some cases, loans to larger mortgage originators may be financed for up to 60 days. Warehouse purchase program loans are collectively evaluated for impairment and are purchased under several contractual requirements, providing safeguards to the Company. To date, the Company has not experienced a loss on these loans and no allowance for credit losses has been allocated to them. 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, 2021, the portfolio consisted of approximately 26% 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 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 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, 2021, loans in the Colorado region represented about 24% of the total portfolio. A large percentage of the Company’s portfolio consists of commercial and residential real estate loans. As of December 31, 2021 and 2020, there were no concentrations of loans related to a single industry in excess of 10% of total loans. As discussed in Note 2. Recent Accounting Standards , on January 1, 2021, the Company adopted ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) (ASC 326). The amount of the allowance represents management's best estimate of current expected credit losses on loans considering available information relevant to assessing collectibility over the loans' contractual terms, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals and modifications unless either of the following applies: management has a reasonable expectation that a troubled debt restructuring will be executed with an individual borrower, or the extension or renewal options are included in the borrower contract and are not unconditionally cancellable by the Company. The Company's allowance balance is estimated using relevant available information, from internal and external sources, relating to past events, current conditions and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, credit quality, or term as well as for changes in environmental conditions, such as changes in unemployment rates, gross domestic product, property values or other relevant factors. The Company utilizes Moody’s Analytics economic forecast scenarios and assigns probability weighting to those scenarios which best reflect management’s views on the economic forecast. The allowance for credit losses is measured on a collective basis for portfolios of loans when similar risk characteristics exist. Loans that do not share risk characteristics are evaluated for expected credit losses on an individual basis and excluded from the collective evaluation. For determining the appropriate allowance for credit losses on a collective basis, the loan portfolio is segmented into pools based upon similar risk characteristics and a lifetime loss-rate model is utilized. For modeling purposes, loan pools include: commercial and industrial, energy, commercial real estate - construction/land development, commercial real estate - owner occupied, commercial real estate - non-owner occupied, agricultural, residential real estate, HELOCs, single-family interim construction, and consumer. Management periodically reassesses each pool to ensure the loans within the pool continue to share similar characteristics and risk profiles and to determine whether further segmentation is necessary. The measurement of expected credit losses is impacted by loan/borrower attributes and certain macroeconomic variables. Management has determined that they are reasonably able to forecast the macroeconomic variables used in the modeling processes with an acceptable degree of confidence for a total of two years then encompassing a reversion process whereby the forecasted macroeconomic variables are reverted to their historical mean utilizing a rational, systematic basis. Management qualitatively adjusts model results for risk factors that are not considered within the modeling processes but are nonetheless relevant in assessing the expected credit losses within the loan pools. These qualitative factor (Q-Factor) adjustments may increase or decrease management's estimate of expected credit losses by a calculated percentage or amount based upon the estimated level of risk. Loans exhibiting unique risk characteristics and requiring an individual allowance are measured based on 1) the present value of expected future cash flows discounted at the loan's 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 individually evaluated loans are measured at the fair value of the collateral. Management continually evaluates the allowance for credit losses based upon the factors noted above. Should any of the factors considered by management change, the Company’s estimate of credit losses could also change and would affect the level of future provision for credit losses. Portions of the allowance may be allocated for specific credits; however, the entire allowance is available for any credit that, in management’s judgment, should be charged off. While the calculation of the allowance for credit losses utilizes management’s best judgment and all the information available, the adequacy of the allowance for credit 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. Loans requiring an individual allowance 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, the status of past due loans are routinely discussed within each lending region as well as credit committee meetings to determine if classification is warranted. The Company’s internal loan review department has implemented an internal risk-based loan review process to identify potential internally classified loans that supplements the independent external loan review. External loan reviews cover a wide range of the loan portfolio, including large lending relationships, specifically targeted loan types, and if applicable recently acquired loan portfolios. As such, the external loan review generally covers loans exceeding $3,000. These reviews include analysis of borrower’s financial condition, payment histories, review of loan documentation and collateral values to determine if a loan should be internally classified. Generally, once classified, an analysis is completed by the credit department to determine the amount of allocated allowance for credit loss required. Expected credit losses for collateral dependent loans, including loans where the borrower is experiencing financial difficulty but foreclosure is not probable, are based on the fair value of the collateral at the reporting date, adjusted for selling costs as appropriate. Following unprecedented declines caused by the pandemic and volatile energy prices, the Texas economy, specifically in the Company’s lending areas of north, central and southeast Texas economy continued robust expansion into the fourth quarter of 2021. The Colorado economy grew at a moderate pace. The stronger sectors of the economy of late include manufacturing, nonfinancial services and residential real estate, while other sectors of the economy where growth slowed were those constrained by supply disruptions and labor shortages. Energy activity and agricultural conditions improved further. Activity in the single-family housing market remained elevated during the reporting period but activity is constrained by labor, lot and material shortages. Overall, the economy is being impacted by persistent labor and supply shortages, and rising costs, which are expected to dampen the recovery. Previous forecasts for a strong return of business travel and events this fall have been adjusted downward by the pandemic resurgence, most recently the Omicron variant. The pandemic continues to have an impact on the economies in the Company's lending areas and the timing and magnitude of recovery cannot be predicted. 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.

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 following table presents loans that were evaluated for expected credit losses on an individual basis and the related specific credit loss allocations, by loan class as of December 31, 2021 and December 31, 2020: December 31, 2021 December 31, 2020 Loan Balance - Specific Allocations Loan Balance - Specific Allocations Commercial $ 38,911 $ 15,958 $ 39,298 $ 8,281 Commercial real estate 24,683 1,553 21,848 243 Commercial construction, land and land development 1,350 562 32 — Residential real estate — — 2,550 — Single-family Interim construction — — — — Agricultural — — 613 — Consumer — — 42 — $ 64,944 $ 18,073 $ 64,383 $ 8,524 Nonperforming loans by loan class at December 31, 2021 (at amortized cost) and December 31, 2020 (at recorded investment), are summarized as follows: Commercial Commercial Construction, Residential Real Estate Single-Family Agricultural Consumer Total December 31, 2021 Nonaccrual loans (1) $ 36,802 $ 15,218 $ 23 $ 1,592 $ — $ — $ 38 $ 53,673 Loans past due 90 days and still accruing 187 — — 1,603 — — — 1,790 Troubled debt restructurings (not included in nonaccrual or loans past due and still accruing) — 1,714 — 161 — — — 1,875 $ 36,989 $ 16,932 $ 23 $ 3,356 $ — $ — $ 38 $ 57,338 December 31, 2020 (2) Nonaccrual loans $ 25,898 $ 20,040 $ 32 $ 2,372 $ — $ 613 $ 42 $ 48,997 Loans past due 90 days and still accruing 433 — — — — — — 433 Troubled debt restructurings (not included in nonaccrual or loans past due and still accruing) — 1,808 — 178 — — — 1,986 $ 26,331 $ 21,848 $ 32 $ 2,550 $ — $ 613 $ 42 $ 51,416 ____________ (1) There is one nonaccrual loan totaling $18 without an allowance for credit loss as of December 31, 2021. Additionally, no interest income was recognized on nonaccrual loans. No significant amounts of accrued interest was reversed during the year ended December 31, 2021. (2) Excluded loans acquired with deteriorated credit quality under prior GAAP The accrual of interest is discontinued on a loan when management believes that, after considering collection efforts and other factors, the borrower's financial condition is such that collection of interest is doubtful, as well as when required by regulatory provisions. Regulatory provisions would typically require the placement of a loan on non-accrual status if 1) principal or interest has been in default for a period of 90 days or more unless the loan is both well secured and in the process of collection or 2) full payment of principal and interest is not expected. 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 generally returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. The restructuring of a loan is considered a “troubled debt restructuring” (TDR) 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. Modifications primarily relate to extending the amortization periods of the loans and interest rate concessions. The modifications during the reported periods did not materially impact the Company’s determination of the allowance for credit losses. The amortized cost basis and recorded investment in troubled debt restructurings, including those on nonaccrual, was $2,918 and $2,564 as of December 31, 2021 and 2020, respectively. Following is a summary of loans modified under troubled debt restructurings during the years ended December 31, 2021 and 2020: Commercial Commercial Commercial Construction, Residential Single-Family Agricultural Consumer Total Troubled debt restructurings during the year ended December 31, 2021 Number of contracts 2 — — — — — 1 3 Pre-restructuring outstanding recorded investment $ 1,789 $ — $ — $ — $ — $ — $ 6 $ 1,795 Post-restructuring outstanding recorded investment $ 570 $ — $ — $ — $ — $ — $ 6 $ 576 Troubled debt restructurings during the year ended December 31, 2020 Number of contracts — 1 — — — — — 1 Pre-restructuring outstanding recorded investment $ — $ 1,517 $ — $ — $ — $ — $ — $ 1,517 Post-restructuring outstanding recorded investment $ — $ 1,517 $ — $ — $ — $ — $ — $ 1,517 At December 31, 2021 and 2020, there were no loans modified under troubled debt restructurings during the previous twelve month period that subsequently defaulted during the years ended December 31, 2021 and 2020. At December 31, 2021 and 2020, the Company had no commitments to lend additional funds to any borrowers with loans whose terms have been modified under troubled debt restructurings. Under ASC Subtopic 310-40 and federal banking agencies interagency guidance, certain short-term loan modifications made on a good faith basis in response to COVID-19 (as defined by the guidance) are not considered TDRs. Additionally, under section 4013 of the CARES Act, and as amended, banks may elect to suspend the requirement for certain loan modifications to be categorized as a TDR. In response to the COVID-19 pandemic, the Company has implemented prudent modifications allowing for primarily short-term payment deferrals or other payment relief to borrowers with pandemic-related economic hardships, where appropriate, that complies with the above guidance. As such, the Company's TDR loans noted above do not include loans that are modifications to borrowers impacted by COVID-19. As of December 31, 2021, the amount of loans remaining in COVID-19 related deferment was not significant. 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 following table presents information regarding the aging of past due loans by loan class as of December 31, 2021 (at amortized cost) and as of December 31, 2020 (at recorded investment): Loans Loans Total Past Current Total December 31, 2021 Commercial $ 1,041 $ 11,056 $ 12,097 $ 1,971,789 $ 1,983,886 Mortgage warehouse — — — 788,848 788,848 Commercial real estate 2,861 11,784 14,645 6,602,810 6,617,455 Commercial construction, land and land development — — — 1,180,181 1,180,181 Residential real estate 3,838 1,913 5,751 1,294,371 1,300,122 Single-family interim construction 1,290 — 1,290 379,337 380,627 Agricultural 16 — 16 106,496 106,512 Consumer 216 9 225 81,590 81,815 $ 9,262 $ 24,762 $ 34,024 $ 12,405,422 $ 12,439,446 December 31, 2020 (1) Commercial $ 3,243 $ 13,227 $ 16,470 $ 2,393,013 $ 2,409,483 Mortgage warehouse — — — 1,453,797 1,453,797 Commercial real estate 2,434 16,790 19,224 5,921,723 5,940,947 Commercial construction, land and land development 19 — 19 1,230,524 1,230,543 Residential real estate 5,169 1,028 6,197 1,341,587 1,347,784 Single-family interim construction — — — 326,575 326,575 Agricultural — 1 1 84,896 84,897 Consumer 86 41 127 67,156 67,283 10,951 31,087 42,038 12,819,271 12,861,309 Acquired with deteriorated credit quality 624 3,219 3,843 210,943 214,786 $ 11,575 $ 34,306 $ 45,881 $ 13,030,214 $ 13,076,095 ____________ (1) Presented under prior GAAP The Company’s internal classified report is segregated into the following categories: 1) Pass/Watch, 2) Special Mention, 3) Substandard and 4) Doubtful. The loans placed in the Pass/Watch category reflect the Company’s opinion that the loans reflect potential weakness that 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 and may be considered impaired. There is a 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 and the possibility of loss is extremely high. Management considers the guidance in ASC 310-20 when determining whether a modification, extension or renewal of a loan constitutes a current period origination. Generally, current period renewals of credit are re-underwritten at the point of renewal and considered current period originations for purposes of the table below. The following summarizes the amortized cost basis of loans by year of origination/renewal and credit quality indicator by class of loan as of December 31, 2021: Revolving Loans Converted to Term Loans Term Loans by Year of Origination or Renewal Revolving Loans December 31, 2021 2021 2020 2019 2018 2017 Prior Total Commercial Pass $ 422,810 $ 183,433 $ 98,059 $ 78,357 $ 81,620 $ 255,213 $ 690,242 $ 5,231 $ 1,814,965 Pass/Watch 260 3,010 1,019 3,135 11,688 65 18,768 3,319 41,264 Special Mention 1,411 117 8,517 7,244 195 4,571 12,885 — 34,940 Substandard 30,277 605 16,041 94 2,478 18,331 13,006 1,988 82,820 Doubtful — — — — — — 9,897 — 9,897 Total commercial $ 454,758 $ 187,165 $ 123,636 $ 88,830 $ 95,981 $ 278,180 $ 744,798 $ 10,538 $ 1,983,886 Mortgage warehouse Pass $ 788,848 $ — $ — $ — $ — $ — $ — $ — $ 788,848 Pass/Watch — — — — — — — — — Special Mention — — — — — — — — — Substandard — — — — — — — — — Doubtful — — — — — — — — — Total mortgage warehouse $ 788,848 $ — $ — $ — $ — $ — $ — $ — $ 788,848 Commercial real estate Pass $ 2,181,292 $ 1,198,508 $ 830,902 $ 645,470 $ 504,126 $ 626,292 $ 71,850 $ 4,320 $ 6,062,760 Pass/Watch 54,671 18,591 39,045 60,955 30,196 74,762 752 1,319 280,291 Special Mention 56,142 16,770 37,331 29,962 17,649 20,100 — — 177,954 Substandard 36,263 16,118 1,136 11,901 281 29,686 1,065 — 96,450 Doubtful — — — — — — — — — Total commercial real estate $ 2,328,368 $ 1,249,987 $ 908,414 $ 748,288 $ 552,252 $ 750,840 $ 73,667 $ 5,639 $ 6,617,455 Revolving Loans Converted to Term Loans Term Loans by Year of Origination or Renewal Revolving Loans December 31, 2021 2021 2020 2019 2018 2017 Prior Total Commercial construction, land and land development Pass $ 618,288 $ 262,136 $ 98,007 $ 85,596 $ 13,751 $ 14,939 $ 18,586 $ — $ 1,111,303 Pass/Watch 17,899 10,459 6,869 — — 84 — — 35,311 Special Mention 3,780 — — — 1,909 — — — 5,689 Substandard 11,601 — 387 14,489 28 1,373 — — 27,878 Doubtful — — — — — — — — — Total commercial construction, land and land development $ 651,568 $ 272,595 $ 105,263 $ 100,085 $ 15,688 $ 16,396 $ 18,586 $ — $ 1,180,181 Residential real estate Pass $ 408,402 $ 267,147 $ 190,890 $ 114,616 $ 88,295 $ 149,871 $ 60,212 $ 2,344 $ 1,281,777 Pass/Watch 1,019 487 1,270 405 2,331 4,179 169 — 9,860 Special Mention 657 — 568 129 250 1,043 126 — 2,773 Substandard 640 369 384 519 774 2,974 52 — 5,712 Doubtful — — — — — — — — — Total residential real estate $ 410,718 $ 268,003 $ 193,112 $ 115,669 $ 91,650 $ 158,067 $ 60,559 $ 2,344 $ 1,300,122 Single-family interim construction Pass $ 305,267 $ 59,584 $ 2,801 $ 312 $ — $ — $ 12,663 $ — $ 380,627 Pass/Watch — — — — — — — — — Special Mention — — — — — — — — — Substandard — — — — — — — — — Doubtful — — — — — — — — — Total single-family interim construction $ 305,267 $ 59,584 $ 2,801 $ 312 $ — $ — $ 12,663 $ — $ 380,627 Agricultural Pass $ 36,442 $ 15,005 $ 4,454 $ 8,033 $ 12,229 $ 4,773 $ 18,993 $ — $ 99,929 Pass/Watch — 526 1,462 52 1,035 — 3,502 — 6,577 Special Mention — — — — — — — — — Substandard — — — — — 6 — — 6 Doubtful — — — — — — — — — Total agricultural $ 36,442 $ 15,531 $ 5,916 $ 8,085 $ 13,264 $ 4,779 $ 22,495 $ — $ 106,512 Consumer Pass $ 10,568 $ 9,496 $ 2,706 $ 710 $ 308 $ 181 $ 57,744 $ 43 $ 81,756 Pass/Watch — — — — 1 — — — 1 Special Mention — — — — — — — — — Substandard 30 2 — — 9 17 — — 58 Doubtful — — — — — — — — — Total consumer $ 10,598 $ 9,498 $ 2,706 $ 710 $ 318 $ 198 $ 57,744 $ 43 $ 81,815 Revolving Loans Converted to Term Loans Term Loans by Year of Origination or Renewal Revolving Loans December 31, 2021 2021 2020 2019 2018 2017 Prior Total Total loans Pass $ 4,771,917 $ 1,995,309 $ 1,227,819 $ 933,094 $ 700,329 $ 1,051,269 $ 930,290 $ 11,938 $ 11,621,965 Pass/Watch 73,849 33,073 49,665 64,547 45,251 79,090 23,191 4,638 373,304 Special Mention 61,990 16,887 46,416 37,335 20,003 25,714 13,011 — 221,356 Substandard 78,811 17,094 17,948 27,003 3,570 52,387 14,123 1,988 212,924 Doubtful — — — — — — 9,897 — 9,897 Total loans $ 4,986,567 $ 2,062,363 $ 1,341,848 $ 1,061,979 $ 769,153 $ 1,208,460 $ 990,512 $ 18,564 $ 12,439,446 A summary of loans at recorded investment by credit quality indicator by class presented under prior GAAP as of December 31, 2020, is as follows: Pass Pass/ Special Mention Substandard Doubtful Total December 31, 2020 Commercial $ 2,247,059 $ 55,960 $ 38,186 $ 97,403 $ 10,091 $ 2,448,699 Mortgage warehouse 1,453,797 — — — — 1,453,797 Commercial real estate 5,379,801 306,884 317,580 92,411 — 6,096,676 Construction, land and land development 1,125,132 46,026 43,383 31,260 — 1,245,801 Residential real estate 1,332,757 6,296 5,726 7,686 — 1,352,465 Single-family interim construction 323,800 2,775 — — — 326,575 Agricultural 76,951 6,194 1,205 664 — |

Junior Subordinated Debentures | Junior Subordinated Debentures The Company has formed or acquired nine statutory business trusts (the Trusts) for the purpose of issuing trust preferred securities. Each of the Trusts have 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. The Company may redeem the debentures, which are intended to qualify as Tier 1 capital, at the Company’s option, subject to approval of the Federal Reserve. As of December 31, 2021 and 2020, the carrying amount of debentures outstanding totaled $54,221 and $54,023, respectively.

Commitments and Contingencies Disclosure [Abstract] | |
Off-Balance Sheet Arrangements, Commitments and Contingencies | Off-Balance Sheet Arrangements, 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, 2021 and 2020, the approximate amounts of these financial instruments were as follows: December 31, 2021 2020 Commitments to extend credit $ 2,770,036 $ 2,268,216 Standby letters of credit 30,007 25,917 $ 2,800,043 $ 2,294,133 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. Allowance For Credit Losses on Off-Balance Sheet Credit Exposures The allowance for credit losses on off-balance sheet credit exposures is calculated under ASC 326, representing expected credit losses over the contractual period for which the Company is exposed to credit risk resulting from a contractual obligation to extend credit. Off-balance sheet credit exposures primarily consist of amounts available under outstanding lines of credit and letters of credit detailed in the table above. The allowance for credit losses on off-balance sheet credit exposures is estimated by loan segment at each balance sheet date using the same methodologies as portfolio loans, taking into consideration the likelihood that funding will occur based on historical utilization rates. The allowance is included in other liabilities on the Company’s consolidated balance sheets. The allowance for credit losses on off-balance sheet commitments was as follows: December 31, 2021 2020 2019 Balance at beginning of period $ — $ — $ — Impact of CECL adoption 1,113 — — Provision for off-balance sheet credit exposure 3,609 — — Balance at end of period $ 4,722 $ — $ — 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. The Bank is a party to a legal proceeding inherited in connection with its acquisition of BOH Holdings, Inc. and its subsidiary, Bank of Houston (BOH). The plaintiffs in the case are alleging that the Bank aided and abetted or participated in a fraudulent scheme. The 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. |

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 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, 2021 and 2020 by level within the ASC Topic 820 fair value measurement hierarchy: Fair Value Measurements at Reporting Date Using Assets/ Quoted Prices Significant Significant December 31, 2021 Assets: Investment securities available for sale: U.S. treasuries $ 174,996 $ — $ 174,996 $ — Government agency securities 444,675 — 444,675 — Obligations of state and municipal subdivisions 432,760 — 432,760 — Corporate bonds 34,796 — 34,796 — Mortgage-backed securities guaranteed by FHLMC, FNMA and GNMA 918,550 — 918,550 — Other securities 950 — 950 — Loans held for sale, fair value option elected (1) 28,249 — 28,249 — Derivative financial instruments: Interest rate lock commitments 1,029 — 1,029 — Forward mortgage-backed securities trades 27 — 27 — Loan customer counterparty 6,459 — 6,459 — Financial institution counterparty 1,078 — 1,078 — Liabilities: Derivative financial instruments: Interest rate swaps - cash flow hedge 1,158 — 1,158 — Interest rate lock commitments 4 — 4 — Forward mortgage-backed securities trades 21 — 21 — Loan customer counterparty 1,073 — 1,073 — Financial institution counterparty 6,772 — 6,772 — December 31, 2020 Assets: Investment securities available for sale: U.S. treasuries $ 44,708 $ — $ 44,708 $ — Government agency securities 249,017 — 249,017 — Obligations of state and municipal subdivisions 393,165 — 393,165 — Corporate bonds 22,102 — 22,102 — Mortgage-backed securities guaranteed by FHLMC, FNMA and GNMA 443,501 — 443,501 — Other securities 1,200 — 1,200 — Loans held for sale, fair value option elected (1) 71,769 — 71,769 — Derivative financial instruments: Interest rate lock commitments 3,515 — 3,515 — Loan customer counterparty 20,159 — 20,159 — Liabilities: Derivative financial instruments: Forward mortgage-backed securities trades 568 — 568 — Financial institution counterparty 21,306 — 21,306 — ____________ (1) At December 31, 2021 and 2020, loans held for sale for which the fair value option was elected had an aggregate outstanding principal balance of $27,176 and $68,670, respectively. 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, 2021. 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. Investment securities 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. Loans held for sale 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 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. This election allows for a more effective offset of the changes in fair values of the assets and the mortgage related derivative instruments used to economically hedge them without the burden of complying with the requirements for hedge accounting under ASC 815, Derivatives and Hedging. Mortgage loans held for sale, for which the fair value option was elected, 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. Derivatives The Company utilizes interest rate swaps to hedge exposure to interest rate risk and variability of cash flows associated to changes in the underlying interest rate of the hedged item. These hedging interest rate swaps are classified as a cash flow hedge. The Company utilizes a third-party vendor for derivative valuation purposes. These vendors determine the appropriate fair value based on a net present value calculation of the cash flows related to the interest rate swaps using primarily observable market inputs such as interest rate yield curves (Level 2 inputs). 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. 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, 2021 and 2020, for which a nonrecurring change in fair value has been recorded: Fair Value Measurements at Reporting Date Using Assets Quoted Prices Significant Significant Period Ended December 31, 2021 Assets: Individually evaluated loans $ 11,204 $ — $ — $ 11,204 $ 3,526 December 31, 2020 Assets: Individually evaluated loans $ 16,903 $ — $ — $ 16,903 $ 13,041 Individually evaluated 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 underlying 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. In addition, management's discounting criteria may vary for loans secured by non-real estate collateral such as inventory, oil and gas reserves, accounts receivable, equipment or other business assets. Therefore, the Company has categorized its individually evaluated loans as Level 3. Other real estate owned 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 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. There was no other real estate owned remeasured during the years ended December 31, 2021 and 2020. 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, 2021 and 2020, 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, 2021 and 2020: Fair Value Measurements at Reporting Date Using Carrying Estimated Quoted Prices Significant Significant December 31, 2021 Financial assets: Cash and cash equivalents $ 2,608,444 $ 2,608,444 $ 2,608,444 $ — $ — Certificates of deposit held in other banks 3,245 3,246 — 3,246 — Loans held for sale, at cost 3,875 3,982 — 3,982 — Loans, net 12,290,740 12,415,366 — — 12,415,366 FHLB of Dallas stock and other restricted stock 21,573 21,573 — 21,573 — Accrued interest receivable 49,636 49,636 — 49,636 — Financial liabilities: Deposits 15,553,908 15,553,645 — 15,553,645 — Accrued interest payable 5,301 5,301 — 5,301 — FHLB advances 150,000 128,555 — 128,555 — Other borrowings 283,371 303,250 — 303,250 — Junior subordinated debentures 54,221 45,501 — 45,501 — Off-balance sheet assets (liabilities): Commitments to extend credit — — — — — Standby letters of credit — — — — — December 31, 2020 Financial assets: Cash and cash equivalents $ 1,813,987 $ 1,813,987 $ 1,813,987 $ — $ — Certificates of deposit held in other banks 4,482 4,595 — 4,595 — Loans held for sale, at cost 10,878 11,138 — 11,138 — Loans, net 12,978,238 13,093,698 — — 13,093,698 FHLB of Dallas stock and other restricted stock 20,305 20,305 — 20,305 — Accrued interest receivable 60,581 60,581 — 60,581 — Financial liabilities: Deposits 14,398,927 14,407,596 — 14,407,596 — Accrued interest payable 7,397 7,397 — 7,397 — FHLB advances 375,000 371,175 — 371,175 — Other borrowings 312,175 327,150 — 327,150 — Junior subordinated debentures 54,023 42,624 — 42,624 — 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, 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: 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. 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 estimated fair value approximates carrying value for short-term borrowings. 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 published Bloomberg US Financials BB rated corporate bond index yield. 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 accounts for its derivative financial instruments in accordance with ASC Topic 815 which requires all derivative instruments to be carried at fair value on the balance sheet. The Company has designated certain derivative instruments used to manage interest rate risk as hedge relationships with certain assets, liabilities or cash flows being hedged. Certain derivatives used for interest rate risk management are not designated in a hedge relationship 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. Derivative instruments designated in a hedge relationship to mitigate exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivative instruments designated in a hedge relationship to mitigate exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. The Company formally documents the relationship between derivatives and hedged items, as well as the risk-management objective and the strategy for undertaking hedge transactions at the inception of the hedge relationship. This documentation includes linking the fair value or cash flow hedges to the specific assets and liabilities on the balance sheet or the specific firm commitments or forecasted transaction. The Company assesses, both at the hedge's inception and on an ongoing basis, whether the derivative instruments that are used are highly effective in offsetting changes in fair values or cash flows of the hedged items. The Company discontinues hedge accounting when it determines that the derivative is no longer effective in offsetting changes in the fair value or cash flows of the hedged item, the derivative is settled or terminates, a hedged forecasted transaction is no longer probable, a hedged firm commitment is no longer firm, or treatment of the derivative as a hedge is no longer appropriate or intended. The Company's objectives in using interest rate derivatives are to add stability to interest income and to manage its exposure to interest rate movements. To accomplish this objective, the Company uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of fixed-rate amounts from a counterparty in exchange for the Company making variable-rate payments over the life of the agreements without exchange of the underlying notional amount. During the second quarter of 2021, the Company entered into two interest rate swap derivatives with an aggregated notional amount of $100,000 that were designated as cash flow hedges. The derivatives are intended to hedge the variable cash flows associated with certain existing variable-interest rate loans and were determined to be effective during the year ended December 31, 2021. For derivatives designated and that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in accumulated other comprehensive income and subsequently reclassified into interest income in the same period that the hedged transaction affects earnings. Amounts of loss recognized in accumulated other comprehensive income related to derivatives was $359, net of tax, and the amounts that were reclassified to interest income as interest payments were received on the Company’s variable-rate loans was $472, net of tax, during and for the year ended December 31, 2021, respectively. During the next twelve months, the Company estimates that $513 will be reclassified as an increase to interest income. Through its mortgage banking division, 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. The Company manages 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 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. The following table provides the outstanding notional balances and fair values of outstanding derivative positions at December 31, 2021 and 2020: Outstanding Notional Balance Asset Derivative Liability Derivative December 31, 2021 Derivatives designated as hedging instruments: Interest rate swaps - cash flow hedge $ 100,000 $ — $ 1,158 Derivatives not designated as hedging instruments: Interest rate lock commitments 34,064 1,029 4 Forward mortgage-backed securities trades 30,500 27 21 Commercial loan interest rate swaps: Loan customer counterparty 254,935 6,459 1,073 Financial institution counterparty 254,935 1,078 6,772 December 31, 2020 Derivatives not designated as hedging instruments: Interest rate lock commitments $ 116,795 $ 3,515 $ — Forward mortgage-backed securities trades 104,000 — 568 Commercial loan interest rate swaps: Loan customer counterparty 335,370 20,159 — Financial institution counterparty 335,370 — 21,306 The commercial loan customer counterparty weighted average received and paid interest rates for interest rate swaps outstanding were as follows: Weighted Average Interest Rate December 31, 2021 December 31, 2020 Received Paid Received Paid Loan customer counterparty 4.12 % 2.40 % 4.08 % 2.32 % The credit exposure related to interest rate swaps is limited to the net favorable value of all swaps by each counterparty, which was approximately $7,537 at December 31, 2021. In some cases collateral may be required from the counterparties involved if the net value of the derivative instruments exceeds a nominal amount. Collateral levels are monitored and adjusted on a regular basis for changes in interest rate swap values. At December 31, 2021 and 2020, cash of $20,491 and $23,829 and securities of $3,168 and $6,494 were pledged as collateral for these derivatives, respectively. The Company has entered into credit risk participation agreements with financial institution counterparties for interest rate swaps related to loans in which the Company is either a participant or a lead bank. Risk participation agreements entered into as a participant bank provide credit protection to the financial institution counterparty should the borrower fail to perform on its interest rate derivative contract with that financial institution. The Company is party to one risk participation agreement as a participant bank having a notional amount of $5,121 at December 31, 2021. Risk participation agreements entered into as the lead bank provide credit protection to the Company should the borrower fail to perform on its interest rate derivative contract. The Company is party to one risk participation agreement as the lead bank having a notional amount of $9,348 at December 31, 2021. The changes in the fair value of interest rate lock commitments and the forward sales of mortgage-backed securities are recorded in mortgage banking revenue. These gains and losses were not attributable to instrument-specific credit risk. For interest rate swaps, because the Company acts as an intermediary for our customer, changes in the fair value of the underlying derivative contracts substantially offset each other and do not have a material impact on the results of operations. A summary of derivative activity and the related impact on the consolidated statements of income for the years ended December 31, 2021, 2020 and 2019 was as follows: Income Statement Location Years Ended December 31, 2021 2020 2019 Derivatives designated as hedging instruments Interest rate swaps - cash flow hedges Interest and fees on loans $ 584 $ — $ — Derivatives not designated as hedging instruments Interest rate lock commitments Mortgage banking revenue (2,490) 2,668 25 Forward mortgage-backed securities trades Mortgage banking revenue 574 (505) 163 |

Share-based Payment Arrangement [Abstract] | |
Stock Awards | Stock Awards The Company grants common stock awards to certain employees of the Company. In April 2013, the Board of Directors adopted the 2013 Equity Incentive Plan (2013 Plan). All stock awards issued under expired plans prior to 2013 are fully vested. Under the 2013 Plan, the Compensation Committee may grant awards to certain employees of the Company in the form of restricted stock, restricted stock rights, restricted stock units, qualified and nonqualified stock options, performance share awards and other equity-based awards. The 2013 Plan, as amended, has 2,300,000 reserved shares of common stock to be awarded by the Company's compensation committee. As of December 31, 2021, there were 1,070,419 shares remaining available for grant for future awards. The shares currently issued under the 2013 Plan are restricted stock awards and performance stock units. Restricted stock awarded to employees vest evenly over the required employment period, generally ranging from one three four Restricted Stock Awards The following table summarizes the activity in nonvested restricted stock awards for the years ended December 31, 2021 and 2020: Restricted Stock Awards Number of Weighted Average Nonvested shares, December 31, 2020 468,800 $ 49.01 Granted during the period 115,463 66.10 Vested during the period (185,447) 51.18 Forfeited during the period (35,265) 50.23 Nonvested shares, December 31, 2021 363,551 $ 53.14 Nonvested shares, December 31, 2019 284,861 $ 58.63 Granted during the period 310,290 43.54 Vested during the period (115,436) 58.08 Forfeited during the period (10,915) 48.37 Nonvested shares, December 31, 2020 468,800 $ 49.01 Compensation expense related to these awards is recorded based on the fair value of the award at the date of grant and totaled $8,984, $8,450 and $7,808 for the years ended December 31, 2021, 2020 and 2019, respectively. Compensation expense is recorded in salaries and employee benefits in the accompanying consolidated statements of income. At December 31, 2021, future compensation expense is estimated to be $12,700 and will be recognized over a remaining weighted average period of 2.22 years. The fair value of common stock awards that vested during the years ended December 31, 2021, 2020 and 2019 was $12,651, $5,602 and $8,725, respectively. The Company has recorded $(691), $243 and $21 in excess tax (benefit) expense on vested restricted stock to income tax expense for the years ended December 31, 2021, 2020 and 2019, respectively. There were no modifications of stock agreements during 2021, 2020 and 2019 that resulted in significant additional incremental compensation costs. At December 31, 2021, the future vesting schedule of the nonvested restricted stock awards is as follows: Number of Shares First year 158,463 Second year 118,975 Third year 77,350 Fourth year 8,763 Total nonvested shares 363,551 Performance Stock Units Performance stock units represent shares potentially issuable in the future. The number of shares issued is based upon the measure of the Company's achievement of its relative adjusted return on average tangible common equity, as defined by the Company, over the award's performance period as compared to an identified peer group's achievement over the same performance period. The number of shares issuable under each performance award is the product of the award target and the award payout percentage for the given level of achievement which ranges from 0% to 150% of the target. The following table summarizes the activity in nonvested performance stock units at target award level for the years ended December 31, 2021 and 2020: Performance-based Restricted Stock Units Number of Weighted Average Nonvested shares, December 31, 2020 89,300 $ 38.29 Granted during the period 25,198 63.92 Nonvested shares, December 31, 2021 114,498 $ 43.93 Nonvested shares, December 31, 2019 — $ — Granted during the period 89,300 38.29 Nonvested shares, December 31, 2020 89,300 $ 38.29 Compensation expense related to performance stock units is estimated each period based on the fair value of the target stock unit at the grant date and the most probable level of achievement of the performance condition, adjusted for the passage of time within the vesting periods of the awards. Compensation expense related to these awards was $1,707 and $0 for the years ended December 31, 2021 and 2020, respectively. As of December 31, 2021, the unrecognized compensation expense assuming the target attainment is estimated to be $3,323, while the estimated maximum payout rate is $5,838 . The remaining performance period over which the expense will be recognized is 2.49 years. |

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. Tier 2 capital for the Company includes permissible portions of the Company's subordinated notes. The permissible portion of qualified subordinated notes decreases 20% per year during the final five years of the term of the notes. The Company is subject to the Basel III regulatory capital framework (the Basel III Capital Rules). The Basel III Capital Rules require that the Company maintain a 2.5% capital conservation buffer above the minimum risk-based capital adequacy requirements. 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. As discussed in Note 1. Summary of Significant Accounting Policies , in connection with the adoption of ASC 326, the Company recognized an after-tax cumulative effect reduction to retained earnings of $53,880 on January 1, 2021. In February 2019, the federal bank regulatory agencies issued a final rule that revised certain capital regulations under CECL and included a transition option that allows banking organizations to phase in, over a three-year period, the day-one adverse effects of CECL on their regulatory capital ratios (three-year transition option). The Company elected to adopt the three-year transition option and the deferral has been applied in the December 31, 2021 capital ratios presented below. 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, 2021 and 2020, the Company and the Bank meet all capital adequacy requirements to which they are subject, including the capital buffer requirement. As of December 31, 2021 and 2020, 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 that management believes have changed the Bank’s category. The following table presents actual capital amounts and required ratios under Basel III Capital Rules for the Company and Bank as of December 31, 2021 and December 31, 2020.

On October 22, 2020, the Company's board of directors authorized a $150,000 stock repurchase program allowing the Company to purchase shares of its common stock through October 31, 2021. On August 26, 2021, the Company extended the stock repurchase program through December 31, 2021. Under this program, the Company repurchased 419,098 shares at a total cost of $29,241 for the year ended December 31, 2021, and 109,548 shares at a total cost of $5,660 for the year ended December 31, 2020. In December 2021, upon the expiration of the current plan, the Company's Board established the 2022 Stock Repurchase Plan, which provides for the repurchase of up to $160,000 of common stock through December 31, 2022. Federal bank regulators have adopted final rules that, among other things, eliminated the standalone prior approval requirement for any repurchase of common stock. However, the Company remains subject to a Federal Reserve Board guideline that requires consultation with the Federal Reserve regarding plans for share repurchases. The Company’s repurchases of its common stock may be subject to a prior approval or notice requirement under other regulations, policies or supervisory expectations of the Federal Reserve Board. |

Accounting Policies [Abstract] | |
Basis of Presentation | Basis of presentation: The accompanying consolidated financial statements include the accounts of IBG and all other entities in which IBG has controlling financial interest. All material intercompany transactions and balances have been eliminated in consolidation. In addition, the Company wholly-owns nine statutory business trusts that were formed for the purpose of issuing trust preferred securities and do not meet the criteria for consolidation (See Note 11. Junior Subordinated Debentures ). 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. |
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 and disclosure 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 GAAP 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 credit 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. Restricted cash: The Company maintains cash collateral balances which have been pledged to derivative counterparties and are legally restricted as to use. |
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: Debt securities that management has the positive intent and ability to hold to maturity are classified as held to maturity and recorded at amortized cost. Debt securities that the Company intends to hold for an indefinite period of time, but not necessarily to maturity are classified as available for sale. 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. 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. The amortization of premiums and accretion of discounts, computed by the interest method generally over their contractual lives, are recognized in interest income. Premiums on callable securities are amortized to their earliest call date. Realized gains or losses, determined on the basis of the cost of specific securities sold, are included in earnings on the trade date. As of December 31, 2021 and 2020, all of the Company's securities were classified as available for sale. |
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 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. |
Loans, net | Loans held for investment: 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 or costs and an allowance for credit losses. Loan origination fees, net of direct origination costs, are deferred and recognized as an adjustment to the related loan yield using the effective interest method without anticipating prepayments. Further information regarding the Company's accounting policies related to past due loans, non-accrual loans, collateral dependent loans and troubled-debt restructurings is presented in Note 5. Loans, Net and Allowance for Credit Losses on Loans . |
Acquired loans | Acquired loans: In accordance with ASC 326, Measurement of Credit Losses on Financial Instruments , loans acquired in connection with a business combination are recorded at their acquisition-date fair value. The allowance for credit losses related to the acquired loan portfolio is not carried over. Acquired loans are classified into two categories based on the credit risk characteristics of the underlying borrowers as either purchased credit deteriorated (PCD) loans, or loans with no evidence of credit deterioration (non-PCD). PCD loans are defined as a loan or pool of loans that have experienced more-than-insignificant credit deterioration since the origination date. For PCD loans, an initial allowance is established on the acquisition date using the same methodology as other loans held for investment and combined with the fair value of the loan to arrive at acquisition date amortized cost. Accordingly, no provision for credit losses is recognized on PCD loans at the acquisition date. Subsequent to the acquisition date, changes to the allowance are recognized in the provision for credit losses. Non-PCD loans are pooled into segments together with originated held for investment loans that share similar risk characteristics and have an allowance established on the acquisition date, which is recognized in the current period provision for credit losses. Determining the fair value of the acquired loans involves estimating the principal and interest payment cash flows expected to be collected on the loans and discounting those cash flows at a market rate of interest. For PCD loans, the non-credit discount or premium is allocated to individual loans as determined by the difference between the loan’s unpaid principal balance and amortized cost basis. The non-credit premium or discount is recognized into interest income on a level yield basis over the remaining expected life of the loan. For non-PCD loans, the fair value discount or premium is allocated to individual loans and recognized into interest income on a level yield basis over the remaining expected life of the loan. Prior to January 1, 2021 as further discussed in Note 2. Recent Accounting Standards , loans acquired in a business combination that had evidence of credit impairment and for which it was probable, at acquisition, that the Company would be unable to collect all contractually required payments receivable were considered PCI. PCI loans were accounted for individually or aggregated into pools of loans based on common risk characteristics such as credit grade, loan type, and date of origination. |
Allowance for Credit Losses on Loans | Allowance for credit losses: Refer to Note 2. Recent Accounting Standards for discussion of the change in methodology used to calculate the allowance for credit losses as a result of adopting of ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), effective January 1, 2021. Allowance for credit losses - loans : In accordance with ASC 326, Measurement of Credit Losses on Financial Instruments , the allowance for credit losses on loans is a valuation account that is deducted from the amortized cost basis of loans to present management's best estimate of the net amount expected to be collected. Loans, or portions thereof, are charged-off against the allowance for credit losses when management believes that collectability of the principal is unlikely. Subsequent recoveries, if any, are credited to the allowance. The allowance is increased (decreased) by provisions (or reversals of) reported in the income statement as a component of provision for credit losses. Management has made the accounting policy election to exclude accrued interest receivable on loans from the estimate of credit losses and reports accrued interest separately in other assets in the consolidated balance sheets. Further information regarding Company policies and methodology used to estimate the allowance for credit losses on loans is presented in Note 5. Loans, Net and Allowance for Credit Losses on Loans . The Company's allowance balance is estimated using relevant available information, from internal and external sources, relating to past events, current conditions and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, credit quality, or term as well as for changes in environmental conditions, such as changes in unemployment rates, gross domestic product, property values or other relevant factors. The Company utilizes Moody’s Analytics economic forecast scenarios and assigns probability weighting to those scenarios which best reflect management’s views on the economic forecast. The allowance for credit losses is measured on a collective basis for portfolios of loans when similar risk characteristics exist. Loans that do not share risk characteristics are evaluated for expected credit losses on an individual basis and excluded from the collective evaluation. For determining the appropriate allowance for credit losses on a collective basis, the loan portfolio is segmented into pools based upon similar risk characteristics and a lifetime loss-rate model is utilized. For modeling purposes, loan pools include: commercial and industrial, energy, commercial real estate - construction/land development, commercial real estate - owner occupied, commercial real estate - non-owner occupied, agricultural, residential real estate, HELOCs, single-family interim construction, and consumer. Management periodically reassesses each pool to ensure the loans within the pool continue to share similar characteristics and risk profiles and to determine whether further segmentation is necessary. The measurement of expected credit losses is impacted by loan/borrower attributes and certain macroeconomic variables. Management has determined that they are reasonably able to forecast the macroeconomic variables used in the modeling processes with an acceptable degree of confidence for a total of two years then encompassing a reversion process whereby the forecasted macroeconomic variables are reverted to their historical mean utilizing a rational, systematic basis. Management qualitatively adjusts model results for risk factors that are not considered within the modeling processes but are nonetheless relevant in assessing the expected credit losses within the loan pools. These qualitative factor (Q-Factor) adjustments may increase or decrease management's estimate of expected credit losses by a calculated percentage or amount based upon the estimated level of risk. Loans exhibiting unique risk characteristics and requiring an individual allowance are measured based on 1) the present value of expected future cash flows discounted at the loan's 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 individually evaluated loans are measured at the fair value of the collateral. Management continually evaluates the allowance for credit losses based upon the factors noted above. Should any of the factors considered by management change, the Company’s estimate of credit losses could also change and would affect the level of future provision for credit losses. Portions of the allowance may be allocated for specific credits; however, the entire allowance is available for any credit that, in management’s judgment, should be charged off. While the calculation of the allowance for credit losses utilizes management’s best judgment and all the information available, the adequacy of the allowance for credit 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. |
Allowance for credit losses on securities | Allowance for credit losses - available for sale securities: For available for sale securities in an unrealized loss position, the Company first assesses whether it intends to sell or it is more-likely-than-not that it will be required to sell the securities before recovery of the amortized cost basis. If either of these criteria is met, the securities amortized cost basis is written down to fair value as a current period expense. If either of the above criteria is not met, the Company evaluates whether the decline in fair value is the result of credit losses or other factors. In making this assessment, management may consider various factors including the extent to which fair value is less than amortized cost, performance of any underlying collateral and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected are compared to the amortized cost basis of the security and any excess of the amortized cost basis over the present value of expected cash flows is recorded as an allowance for credit loss, limited to the amount by which the fair value is less than the amortized cost basis. Any impairment not recorded through an allowance for credit loss is recognized in other comprehensive income as a non credit-related impairment. Changes in the allowance for credit losses are recorded as provision for (or reversal of) credit losses. Available for sale securities are charged-off against the allowance or, in the absence of any allowance, written down through income when deemed uncollectible by management or when either of the aforementioned criteria regarding intent or requirement to sell is met. Allowance for credit losses - held to maturity securities : The allowance for credit losses on held to maturity securities is a valuation account that is deducted from the amortized cost basis of held to maturity securities to present management's best estimate of the net amount expected to be collected. Held to maturity securities are charged-off against the allowance when deemed uncollectible by management. Adjustments to the allowance are reported in the income statement as a component of provision for credit losses. Management measures expected credit losses on held to maturity securities on a collective basis by major security type with each type sharing similar risk characteristics and considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. Management has made the accounting policy election to exclude accrued interest receivable on available for sale and held to maturity securities from the estimate of credit losses and report accrued interest separately in other assets in the consolidated balance sheet. |
Allowance for credit losses on off-balance-sheet credit exposures | Allowance for credit losses on off-balance sheet credit exposures: The allowance for credit losses on off-balance sheet credit exposures is a liability account, calculated in accordance with ASC 326, representing expected credit losses over the contractual period for which the Company is exposed to credit risk resulting from a contractual obligation to extend credit. No allowance is recognized if we have the unconditional right to cancel the obligation. The allowance is reported as a component of other liabilities in the consolidated balance sheets. Adjustments to the allowance are reported in the income statement as a component of provision for credit losses. Further information regarding Company policies and methodology used to estimate the allowance for credit losses on off-balance sheet credit exposures is presented in Note 14. Off-Balance Sheet Arrangements, Commitments and Contingencies . 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. |
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 Leasehold improvements are carried at cost and are depreciated over the shorter of the estimated useful life or the lease period. |
Software | Software: Costs incurred in connection with development or purchase of internal use software and cloud computing arrangements, including in-substance software licenses, are capitalized. Amortization is computed on a straight-line basis over the estimated useful life of the asset, which generally ranges from one |
Leases | Leases: The Company's leases are accounted for under ASC Topic 842, Leases . For operating leases with a term greater than one year, the Company recognizes operating right-of-use (ROU) lease assets and operating lease liabilities, which are recorded in other assets and other liabilities, respectively, in the consolidated balance sheets. The Company determines if an arrangement is a lease at inception. Operating ROU lease assets and related liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate referenced to the Federal Home Loan Bank Secure Connect advance rates for borrowings of similar terms in determining the present value of lease payments. The operating ROU lease asset also includes any lease pre-payments made and excludes lease incentives. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which the Company has elected to account for separately as the non-lease component amounts are readily determinable under most leases. |
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. |
Goodwill and other intangible assets, net | Goodwill and other intangible assets, 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. On January 1, 2020, ASU 2017-04, Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment became effective for the Company as further explained in Note 2. Recent Accounting Standards . Under the guidance, if a reporting unit’s carrying amount exceeds its fair value, an entity will record an impairment charge based on that difference. As of December 31, 2021, the fair value of the Company’s stock price and calculated market capitalization exceeded its carrying value. Core deposit intangibles and other acquired customer relationship intangibles arising from bank acquisitions are amortized on a straight-line basis over their estimated useful lives of ten years and thirteen years, respectively. Other intangible assets 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 other restricted 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. |
Stock based compensation | Stock based compensation: Compensation cost is recognized for restricted stock awards/stock units 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 time-based awards. Compensation expense for performance stock units is recognized over the service period of the award based upon the probable number of units expected to vest. 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. For cash flow hedges, gains and losses on the derivative(s) are recorded in accumulated other comprehensive income and subsequently reclassified into interest income in the same period that the hedged transaction affects earnings. |
Fair values of financial instruments | Fair values of financial instruments: Accounting standards define fair value, establish a framework for measuring fair value in GAAP, 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. 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 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. Investment securities 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. Loans held for sale 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 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. This election allows for a more effective offset of the changes in fair values of the assets and the mortgage related derivative instruments used to economically hedge them without the burden of complying with the requirements for hedge accounting under ASC 815, Derivatives and Hedging. Mortgage loans held for sale, for which the fair value option was elected, 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. Derivatives The Company utilizes interest rate swaps to hedge exposure to interest rate risk and variability of cash flows associated to changes in the underlying interest rate of the hedged item. These hedging interest rate swaps are classified as a cash flow hedge. The Company utilizes a third-party vendor for derivative valuation purposes. These vendors determine the appropriate fair value based on a net present value calculation of the cash flows related to the interest rate swaps using primarily observable market inputs such as interest rate yield curves (Level 2 inputs). 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. 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. 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, 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: 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. 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 estimated fair value approximates carrying value for short-term borrowings. 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 published Bloomberg US Financials BB rated corporate bond index yield. 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 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. The accounting for changes in fair value depends on the intended use of the derivative. Changes in fair value of derivatives designated in a qualifying hedge relationship are recorded in accumulated other comprehensive income. Changes in fair value of derivatives not designated in a qualifying hedge relationship are recognized directly in earnings. All derivatives are carried at fair value in either other assets or other liabilities. See Note 18. Derivative Financial Instruments for further information regarding Company policy. |
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 the initial and subsequent changes in the fair value of the mortgage derivatives. Interest earned on mortgage loans is recorded in interest income. |
Revenue recognition | Revenue recognition: ASC Topic 606, R evenue from Contracts with Customers (ASC 606) , 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. • Investment management and trust - includes income related to providing investment management and trust services to customers under investment management and trust contracts. Also included are fees received from a third party broker-dealer as part of a revenue-sharing agreement for fees earned from customers that are referred to a third party. The investment management fees and referral fees are billed and paid on a quarterly basis and recognized ratably throughout the quarter as performance obligations are satisfied. • Mortgage warehouse purchase program fees - includes fees for the administration and funding of mortgage loans, as well as renewal and application fees received from mortgage originator customers through our mortgage warehouse purchase program. Revenue related to the warehouse program is recognized when the related loan interest is paid off or upon renewal or application. • 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, acquired loan recoveries, 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 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. |
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 Securities and Exchange Commission (SEC) and noted no subsequent events requiring financial statement recognition or disclosure, except as disclosed in Note 22. Subsequent Events . |
Earnings per share | Earnings per share: Basic earnings per common share is calculated as net income available to common shareholders divided by the weighted average number of common shares outstanding during the period. The unvested share-based payment awards that contain rights to nonforfeitable dividends are considered participating securities for this calculation. Diluted earnings per common share includes the dilutive effect of additional potential common shares issuable under participating nonvested restricted stock awards as well as performance stock units (PSUs). The participating nonvested restricted stock awards were not included in dilutive shares as they were anti-dilutive for the years ended December 31, 2021, 2020 and 2019. Proceeds from the assumed exercise of dilutive participating nonvested restricted stock awards and PSUs are assumed to be used to repurchase common stock at the average market price. |
Recent accounting pronouncements | Adoption of new accounting standards ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) (ASC 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13). On January 1, 2020, ASU 2016-13, as amended, became effective for the Company. ASU 2016-13 replaces the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (CECL) methodology. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including loan receivables and held to maturity debt securities. It also applies to off-balance sheet credit exposures not accounted for as insurance (loan commitments, standby letters of credit, financial guarantees, and other similar instruments). The CECL model requires the measurement of all expected credit losses on applicable financial assets based on historical experience, current conditions, and reasonable and supportable forecasts. In addition, ASU 2016-13 includes certain changes to the accounting for available for sale securities such as requiring credit-related impairments to be recognized as an allowance for credit losses rather than as a direct write-down of the securities amortized cost basis when management does not intend to sell or believes that it is more likely than not they will be required to sell securities prior to recovery of the securities amortized cost basis. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) was signed by the President of the United States that included an option for financial institutions to delay the implementation of ASU 2016-13 until the earlier of the termination date of the national emergency declaration by the President or December 31, 2020. On December 27, 2020, the Consolidated Appropriations Act, 2021 (Act 2021), was signed into law which further extended the implementation date of CECL to the earlier of the first day of the entity’s fiscal year that begins after the date on which the COVID-19 national emergency terminates or January 1, 2022. Under the CARES Act provision, the Company elected to delay implementation of ASU 2016-13 and calculated and recorded its provision for credit losses under the incurred loss model that existed prior to ASU 2016-13 for the year ended December 31, 2020. With regard to Act 2021 amendments, the SEC staff indicated it would not object to a registrant early adopting on December 31, 2020, retrospective to January 1, 2020, or January 1, 2021, effective as of January 1, 2021. Under this guidance, the Company elected to adopt ASU 2016-13 with an effective implementation date of January 1, 2021. The Company adopted ASU 2016-13 using the modified retrospective method for all financial assets measured at amortized cost and off-balance sheet credit exposures. As a result of this adoption, the Company recognized a cumulative effect reduction to retained earnings totaling $53,880, net of a recorded deferred tax asset of $15,113, and reclassed $13,035 of allowance for credit loss related to financial assets purchased with credit deterioration (PCD) that were previously classified as purchased credit impaired (PCI) and accounted for under ASC 310-30 as discussed below. Results for periods beginning after January 1, 2021 are presented in accordance with ASU 2016-13 while prior period amounts continue to be reported in accordance with previously applicable GAAP. The Company adopted ASU 2016-13 using the prospective transition approach for PCD assets. In accordance with the standard, management did not reassess whether PCI assets met the criteria of PCD assets as of the date of adoption. On January 1, 2021, the amortized cost basis of the PCD assets were adjusted to reflect the addition of the allowance for credit losses. The remaining noncredit discount (based on the adjusted amortized cost basis) was accreted into interest income at the effective interest rate as of January 1, 2021. The following table illustrates the impact of ASU 2016-13 on the allowances for credit losses as of January 1, 2021, the date of adoption: January 1, 2021 Pre-Adoption Allowance Impact of Adoption Initial allowance on loans purchased with credit deterioration Post-Adoption Allowance Assets: Allowance for credit losses on Loans: Commercial $ 27,311 $ 12,775 $ 4,328 $ 44,414 Commercial real estate 36,698 29,108 7,640 73,446 Commercial construction, land and land development 13,425 22,008 927 36,360 Residential real estate 6,786 (2,255) 140 4,671 Single-family interim construction 2,156 7,179 — 9,335 Agricultural 337 (178) — 159 Consumer 684 (334) — 350 Unallocated 423 (423) — — $ 87,820 $ 67,880 $ 13,035 $ 168,735 Liabilities: Allowance for credit losses on off-balance sheet credit exposures $ — $ 1,113 $ — $ 1,113 ASU 2020-08, Codification Improvements to Subtopic 310-20, Receivables - Nonrefundable Fees and Other Costs . ASU 2020-08 clarifies the accounting for the amortization of purchase premiums for callable debt securities with multiple call dates. ASU 2020-8 was effective for the Company on January 1, 2021 and did not have a significant impact on our financial statements. ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting and subsequent clarifying update ASU 2021-01 Reference Rate Reform (Topic 848); Scope. ASU 2020-04 provides temporary optional guidance to ease the potential burden in accounting for reference rate reform. The new guidance provides optional expedients and exceptions for applying GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. The ASU is intended to help stakeholders during the global market-wide reference rate transition period. ASU 2021-01 clarifies that certain optional expedients and exceptions in ASC 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. ASU 2021-01 also amends the expedients and exceptions in ASC 848 to capture the incremental consequences of the scope clarification and to tailor the existing guidance to derivative instruments affected by the discounting transition. These ASUs were effective upon issuance and generally can be applied through December 31, 2022. The adoption of these ASUs did not significantly impact our financial statements or disclosures. ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The guidance issued in this update simplified the accounting for income taxes by eliminating certain exceptions to the guidance in ASC 740 related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition for deferred tax liabilities for outside basis differences. ASU 2019-12 also simplified aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarified the accounting for transactions that result in a step-up in the tax basis of goodwill. ASU 2019-12 was effective for the Company on January 1, 2021 and did not have a significant impact on our financial statements. 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 became effective for the Company on January 1, 2020 and did not have a significant impact on its financial statements and disclosures. ASU 2018-13, Fair Value Measurement (Topic 820) - Changes to the Disclosure Requirements for Fair Value Measurement. This ASU modified 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 became effective for the Company on January 1, 2020 and did not have a significant impact on its financial statements and disclosures. 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 is not impacted. Under current GAAP, premiums on callable debt securities are generally amortized over the contractual life of the security. ASU 2017-08 became effective for the Company on January 1, 2019 and, upon adoption, the Company recognized a cumulative effect adjustment reducing retained earnings by $856, net of the deferred tax impact, but otherwise did not have a significant impact to the Company's consolidated financial statements and disclosures. ASU 2017-04, Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment. This ASU simplified 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 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 eliminated the prior requirement to calculate a goodwill impairment charge using Step 2, which required an entity to calculate any impairment charge by comparing the implied fair value of goodwill with its carrying amount. ASU 2017-04 became effective for the Company on January 1, 2020, and did not have a significant impact on its financial statements. ASU 2016-02, Leases (Topic 842) |
Mortgage warehouse purchase loans | The Company has a mortgage warehouse purchase program providing mortgage inventory financing for residential mortgage loans originated by mortgage banker clients across a broad geographic scale. Proceeds from the sale of mortgages is the primary source of repayment for warehouse inventory financing via approved investor takeout commitments. These loans typically have a very short duration ranging between a few days to 15 days. In some cases, loans to larger mortgage originators may be financed for up to 60 days. Warehouse purchase program loans are collectively evaluated for impairment and are purchased under several contractual requirements, providing safeguards to the Company. To date, the Company has not experienced a loss on these loans and no allowance for credit losses has been allocated to them. |
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. |
Nonaccrual loan and lease status | The accrual of interest is discontinued on a loan when management believes that, after considering collection efforts and other factors, the borrower's financial condition is such that collection of interest is doubtful, as well as when required by regulatory provisions. Regulatory provisions would typically require the placement of a loan on non-accrual status if 1) principal or interest has been in default for a period of 90 days or more unless the loan is both well secured and in the process of collection or 2) full payment of principal and interest is not expected. 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 generally returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. |
Trouble debt restructuring | The restructuring of a loan is considered a “troubled debt restructuring” (TDR) 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. Modifications primarily relate to extending the amortization periods of the loans and interest rate concessions. |
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. |
Share repurchase plan | Stock repurchase program: From time to time, the Company's board of directors has authorized stock repurchase programs which allow the Company to purchase its common stock generally over a one-year period at various prices in the open market or in privately negotiated transactions. On October 22, 2020, the Company's board of directors authorized a $150,000 stock repurchase program allowing the Company to purchase shares of its common stock through October 31, 2021. On August 26, 2021, the Company extended the stock repurchase program through December 31, 2021. Under this program, the Company repurchased 419,098 shares at a total cost of $29,241 for the year ended December 31, 2021, and 109,548 shares at a total cost of $5,660 for the year ended December 31, 2020. In December 2021, upon the expiration of the current plan, the Company's Board established the 2022 Stock Repurchase Plan, which provides for the repurchase of up to $160,000 of common stock through December 31, 2022. Federal bank regulators have adopted final rules that, among other things, eliminated the standalone prior approval requirement for any repurchase of common stock. However, the Company remains subject to a Federal Reserve Board guideline that requires consultation with the Federal Reserve regarding plans for share repurchases. The Company’s repurchases of its common stock may be subject to a prior approval or notice requirement under other regulations, policies or supervisory expectations of the Federal Reserve Board. |
