Amended the mandatory effective date for ASU 2016-02 (Leases). The amended dates were incorporated into the “anticipated date of adoption” section for the appropriate ASU below. No expected impact to the financial statements, but delays certain ASUs for private companies, and EGCs that elected to use the private company effective dates for new or revised accounting standards. If the Company loses its EGC status during the fiscal year, the Company would be required to review all ASUs as a Public Business Entity (“PBE”) and adopt any ASU effective for PBEs as of the first day of that year. ASU 2019-10 Financial Instruments-Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates Effective immediately, but included here for informational purposes as it relates to the ASU listed in the “description” section. Amended the mandatory effective dates for all entities related to: (i) credit losses - ASU 2016-13; (ii) goodwill - ASU 2017-04; (iii) leases - ASU 2016-02; and (iv) hedging - ASU 2017-12 The amended dates were incorporated into the “anticipated date of adoption” section for the appropriate ASU below. No expected impact to the financial statements, but delays certain ASUs for private companies, smaller reporting companies and EGCs that elected to use the private company effective dates for new or revised accounting standards. If a company loses its EGC status during the fiscal year, the company would be required to review all ASUs as a PBE and adopt any ASU effective for PBEs as of the first day of that year. Standard Anticipated Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2019-04 Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments Updates related to ASU 2016-13 are effective at the same time as ASU 2016-13. Provided an election to measure separately or not measure an allowance for credit losses ("ACL") for accrued interest receivable. Provided an election to write-off uncollectible interest as a reversal of interest income or a charge against the ACL or a combination of both. Clarified that recoveries, including recoveries of amounts expected to be written off and those previously written off, should be incorporated within the estimation of the ACL. Clarified that contractual extensions or renewal options that are not unconditionally cancellable by the lender are considered when determining the contractual term over which expected credit losses are measured. The Company elected to exclude accrued interest receivable from the ACL. The Company has existing practices in place for the timely write-off of uncollectable accrued interest receivable. The Company plans to adjust the historical loss information to reflect the amount of accrued interest that would have been charged off if the entity had not applied a nonaccrual accounting policy. The Company elected to reverse interest income when accrued interest receivable is written off, which is similar to past accounting practice. Additional information regarding the Company's transition to ASU 2016-13 is provided below. Standard Anticipated Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2016-13 Financial Instruments-Credit Losses If the Company maintains its EGC status, the Company is not required to implement this standard until January 2023. The Company expects to adopt this standard on January 1, 2022. Requires an entity to utilize a new impairment model known as the current expected credit loss ("CECL") model to estimate its lifetime expected credit loss and record an allowance that, when deducted from amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. The Company established a committee to formulate and oversee the implementation process including selection, implementation and testing of third-party software. The Company began parallel processing with the existing allowance for loan losses model during the first quarter of 2019 recalibrating inputs as necessary. The Company formulated changes to policies, procedures, disclosures and internal controls that were necessary in order to transition to the new standard. A third-party completed validation of the completeness, accuracy and reasonableness of the model in the fourth quarter of 2021. The Company plans to use a loss-rate ("cohort") method to estimate the expected allowance for credit losses ("ACL") for all loan pools. The Cohort method identifies and captures the balance of a pool of loans with similar risk characteristics, as of a particular point in time to form a cohort, then tracks the respective losses generated by that cohort of loans over their remaining lives, or until the loans are “exhausted” (i.e.; have reached an acceptable point in time at which a significant majority of all losses are expected to have been recognized). The cohort method closely aligns with the Company's incurred loss model. This allows the Company to take advantages of the efficiencies of processes and procedures already in practice. The Company's loan categories will be similar to those used under the current, incurred loss model, but will break out the Commercial loan category into Commercial and Commercial lines of credit. Upon adoption in 2022, a cumulative-effect adjustment, net of tax for the change in the ACL will be recognized in retained earnings. These results include the adoption of a forecast based on several economic assumptions, including unemployment rates and management judgments. Adoption will not materially impact reporting for debt securities as the Company does not currently own held-to-maturity debt securities within the scope of ASU 2016-13. Standard Anticipated Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2016-02 Leases (Topic 842) The Company expects to early adopt this standard on January 1, 2022. Requires lessees and lessors to recognize lease assets and lease liabilities on the balance sheet and disclose key information about leasing arrangements. The update requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach with the option to elect certain practical expedients. The update will also increase disclosures around leases, including qualitative and specific quantitative measures. The Company expects to apply the update as of the beginning of the period of adoption and the Company does not plan to restate comparative periods. The Company expects to elect certain optional practical expedients. The Company performed a search for all property leases and potential embedded leases inside other third-party agreements, The Company's review for embedded leases focused on third-party software as a service ("SAAS") agreements and determined if the Company had the right to control a specified asset over a period of time in exchange for consideration. The Company’s current operating leases relate primarily to five branch locations. The Company expects to record approximately $ 27 million for the lease liability and $ 25 million for the right of use asset on its balance sheet, with an immaterial impact to its income statement compared to the current lease accounting model. Standard Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2021-06 Presentation of Financial Statement (Topic 205), Financial Services - Depository and Lending (Topic 942), and Financial Services - Investment Companies (Topic 946) - Amendments to SEC Paragraphs Pursuant to SEC Final Rule Releases No. 33-10786, Amendments to Financial Disclosures about Acquired and Disposed Businesses, and No. 33- 10835, Update of Statistical Disclosures for Bank and Savings and Loan Registrants Effective on issuance Applicable to fiscal years ending on or after December 15, 2021 ASU adds or amends SEC paragraphs in the Accounting Standards Codification that describe SEC guidance or SEC staff views that the Financial Accounting Standards Board includes as a convenience to Codification users. SEC Release No. 33-10835; 34-89835; and File No. S7- 02-17, updated and codified the Statistical Disclosures for Bank and Savings and Loan Registrants. The amendments update and expand the disclosures that registrants are required to provide, codify certain Guide 3 disclosure items and eliminate other Guide 3 disclosure items that overlap with Commission rules or U.S. Generally Accepted Accounting Principles. In addition, the disclosure requirements were added to a new subpart of Regulation S-K and rescinds Guide 3. The ASU did not have a material impact on the Company's consolidated financial statements, but impacted disclosure requirements in the Company's Form 10-K, including: - Distribution of assets, liabilities and stockholders' equity; - Weighted average yield of each maturity category of debt securities not carried at fair value through earnings; - Maturity analysis of the loan portfolio; - Certain credit ratios, including requiring the disclosure of the allowance for loan losses to total loans, nonaccrual loans to total loans, allowance for loan losses to nonaccrual loans, and net charge-offs to average loans by loan category; - Allowance for loan losses by category; and - average deposit rates paid and amount that are uninsured. ASU 2021-04 Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options December 31, 2021 (early adopted and is being applied as of January 1, 2021) Clarifies and reduces diversity in an issuer's accounting for modifications or exchanges of freestanding equity- classified written call options that remain equity- classified. An issuer should measure the effect of a modification as the difference between the fair value of the modified warrant and the fair value of that warrant immediately before modification. The recognition of the modification depends on the nature of the transaction in which a warrant is modified: (i) Equity issuance - recorded as deferred costs of an equity offering; (ii) Debt origination - recorded as a debt discount if held by the lender or debt issuance costs if held by a third party; (iii) Debt modification - recorded as a fee paid to or received from the creditor, if held by a creditor, and as a third party cost if held by a third party; and (iv) All other modifications - recorded as a dividend that reduces retained earnings. The Company had 113,500 warrants outstanding as of December 31, 2021. The amendments in the ASU did not have a material impact on the Company's year-end or interim consolidated financial statements. Standard Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2018-16 Derivative and Hedging (Topic 815) Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes December 31, 2021 (applied as of January 1, 2021) Permit use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes in addition to the UST, the LIBOR swap rate, the OIS rate based on the Fed Funds Effective Rate, and the SIFMA Municipal Swap Rate. The change will apply prospectively for qualifying new or redesignated hedging relationships entered into on or after the date of adoption. The ASU did not have a material impact on the Company's year-end or interim consolidated financial statements. ASU 2018-15 Intangibles-Goodwill and Other- Internal-Use Software December 31, 2021 (applied as of January 1, 2021) 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. The Company elected to apply the change in accounting principle prospectively. A review of third-party, hosting arrangements, including software-as-a-service ("SaaS") arrangements, that were in the implementation stage was performed in 2021 to ensure applicable implementation costs were capitalized and will be amortized over the service period. SaaS arrangements are service contracts providing the Company with the right to access the cloud provider’s application software over the contract period. As such the Company does not receive a software intangible asset at the contract commencement date. A right to receive future access to the supplier’s software does not, at the contract commencement date, give the customer the power to obtain the future economic benefits flowing from the software itself and to restrict others’ access to those benefits The ASU did not have a material impact on the Company's year-end or interim consolidated financial statements. The Company's previous capitalization policies were similar to the ASU requirements. ASU 2017-12 Derivatives and Hedging (Topic 815) Targeted Improvements to Accounting for Hedging Activities December 31, 2021 (applied as of January 1, 2021) Simplifies and expands the eligible hedging strategies for financial and nonfinancial risks. Enhances the transparency of how hedging results are presented and disclosed. Provides partial relief on the timing of certain aspects of hedge documentation and eliminates the requirement to recognize hedge ineffectiveness separately in earnings. During the year ended December 31, 2021, the Company began entering into cash flow hedges. As of December 31, 2021, the total number of cash flow hedges was 5 with an aggregate notional amount of $ 100 million. The amendments in the ASU did not have a material impact on the Company's year-end or interim consolidated financial statements. Standard Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2020-04: Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting June 30, 2020 The ASU provides optional expedients and exceptions to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The ASU only applies to transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The amendments include: (1) Optional expedients to contract modifications that allow the Company to adjust the effective interest rate of receivables and debt, account for lease modifications as a continuation of the existing lease, and remove the requirement to reassess its original conclusions for contract modifications about whether that contract contains an embedded derivative that is clearly and closely related to the economic characteristics and risks of the host contract under Subtopic 815-15, Derivatives and Hedging— Embedded Derivatives; (2) Exceptions to the guidance in Topic 815 related to changes in the critical terms of a hedging relationship due to reference rate reform; and (3) Optional expedients for cash flow and fair value hedges. The Company had more than $ 1 billion in loans tied to LIBOR as of December 31, 2020. The adoption did not have a material accounting impact on the Company’s consolidated financial position or results of operations. Additionally, LIBOR fallback language has been included in key loan provisions of new and renewed loans in preparation for transition from LIBOR to the new benchmark rate when such transition occurs. This standard is expected to ease the administrative burden in accounting for the future effects of reference rate reform. The ASU allows the Company to recognize the modification related to LIBOR as a continuation of the old contract, rather than a cancellation of the old contract resulting in a write off of unamortized fees and creation of a new contract. ASU 2019-12: Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes January 1, 2020 (Early Adoption) The ASU simplifies the accounting for income taxes. Among other changes, the ASU: (1) Removes the exception to the incremental approach for intraperiod tax allocation when there is a loss from continuing operations and income or a gain from other items; (2) Removes the exception to the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year; (3) Requires an entity to recognize a franchise tax that is partially based on income as an income-based tax and account for any incremental amount incurred as a nonincome based tax; and (4) Requires an entity to reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. The amendments in the ASU did not have a material impact on the Company’s tax methodology, processes, or the Company’s financial statements. Standard Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2018-13: Fair Value Measurement (Topic 820): Disclosure Framework January 1, 2020 Improves the effectiveness of disclosures in the notes to financial statements by facilitating clear communication of the information. The amendments modify certain disclosure requirements of fair value measurements in Topic 820, Fair Value Measurement. Entities are no longer required to disclose transfers between Level 1 and Level 2 of the fair value hierarchy or qualitatively disclose the valuation process for Level 3 fair value measurements. The updated guidance requires disclosure of the changes in unrealized gains and losses for the period included in Other Comprehensive Income for recurring Level 3 fair value measurements. Entities are required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. The additional provisions of the guidance should be adopted prospectively. The eliminated requirements should be adopted retrospectively. The adoption did not have a material impact to the Company’s financial statements. No transfers between Level 1 and Level 2 occurred in 2019 or 2020 and the Company did not have any recurring Level 3 fair value measurements that created an unrealized gain or loss in Other Comprehensive Income. In addition, the Company previously disclosed the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. ASU 2017-04: Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment January 1, 2020 (Early Adoption) Eliminates Step 2 from the goodwill impairment test which required entities to compute the implied fair value of goodwill. An entity should perform an annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. On the date of adoption, there was no impact to the Company’s financial statements. The Company’s process for evaluating goodwill impairment was modified to align with the elimination of Step 2. In the second quarter of 2020, the Company performed a Step 0 analysis then a Step 1 analysis and determined that goodwill was fully impaired. ASU 2016-01: Financial Instruments- Overall (Subtopic 825-10) January 2019 Required equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. Emphasized the existing requirement to use exit prices to measure fair value for disclosure purposes and clarifies that entities should not make use of practicability exceptions in determining the fair value of loans. The Company transferred $ 69 thousand from accumulated other comprehensive loss to retained earnings in January 2019. There was no impact to the income statement on the adoption date. Standard Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2018-07: Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting January 2019 Early adoption Expanded the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees, excluding share-based payments used to effectively provide: (i) financing to the issuer or (ii) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The amendments include: (i) grants are measured at grant-date fair value of the equity instruments; (ii) equity-classified nonemployee share-based payment awards are measured at the grant date;(iii) performance based awards are measured based on the probability of satisfying the performance conditions and (iv) in general, non- employee share-based payment awards will continue to be subject to the requirements of ASC 718 unless modified after the good has been delivered, the service has been rendered, any other conditions necessary to earn the right to benefit from the instrument have been satisfied, and the nonemployee is no longer providing goods or services. The Company had 216,960 stock-based awards to non-employees as of the implementation date, including 116,960 performance- based restricted stock units. The adoption of the ASU allowed the Company to: (i) set the fair market value of the non-employee awards as of the adoption date; and (ii) start to expense the performance-based restricted stock units based on the probability of satisfying the performance conditions. Adoption of ASU 2018-07 required the Company to make a one time transfer of $ 2 million from retained earnings to additional paid in capital. In addition, the Company recorded a $ 306 thousand deferred tax asset that was offset with retained earnings to account for the tax impact. The Company will record forfeitures as they occur and base fair market values on the expected term, like the Company’s accounting for employee-based awards. ASU 2014-09: Revenue from Contracts with Customers January 2019 Amended guidance related to revenue from contracts with customers. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Replaced nearly all existing revenue recognition guidance, including industry specific guidance, established a new control based revenue recognition model, changed the basis for deciding when revenue is recognized over time or at a point in time, provided new and more detailed guidance on specific topics and expands and improves disclosures about revenue. The accounting update did not materially impact the financial statements or recognition of revenues. The update did not apply to revenue associated with financial instruments, including loans and securities that are accounted for under other GAAP, which comprises a significant portion of the Company’s revenue stream. In addition, the Company’s noninterest income is generated by customer transactions or through the passage of time and as a result the pattern or timing of income recognition was not impacted. Note 1: Nature of Operations and Summary of Significant Accounting Policies Organization and Nature of Operations CrossFirst Bankshares, Inc. (consolidated) (the “Company”), a Kansas corporation, is a bank holding company whose principal activities are the ownership and management of its wholly owned subsidiary, CrossFirst Bank (a subsidiary of CrossFirst Bankshares, Inc.) (the “Bank”). The Bank has three wholly owned subsidiaries: (i) CrossFirst Investments, Inc. holds investments in marketable securities; (ii) CFBSA I, LLC that can hold foreclosed assets; and (iii) CFBSA II, LLC that can hold foreclosed assets. The Bank is primarily engaged in providing a full range of banking and financial services to individual and corporate customers through its branches in: (i) Leawood, Kansas; (ii) Wichita, Kansas; (iii) Kansas City, Missouri; (iv) Oklahoma City, Oklahoma; (v) Tulsa, Oklahoma; (vi) Dallas, Texas; (vii) Frisco, Texas; and (viii) Phoenix, Arizona. The Bank is subject to competition from other financial institutions and the regulation of certain federal and state agencies and undergoes periodic examinations by those regulatory authorities. Basis of Presentation The Company’s accounting and reporting policies conform to accounting principles generally accepted in the United States (“GAAP”). The consolidated financial statements include the accounts of the Company; the Bank and its wholl y-owned subsidiaries, CrossFirst Investments, Inc., CFBSA I, LLC and CFBSA II, LLC. All significant intercompany accounts and transactions were eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses, valuation of deferred tax assets, other-than-temporary impairments (“OTTI”), stock based compensation, derivatives, and fair values of financial instruments. Changes in Accounting Principle On December 31, 2021, the Company adopted the Financial Accounting Standards Board (“FASB”) Accounting Standard Update (“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 in the current period of adoption, which was applied on a prospective basis. A description of the nature and reason for the change in accounting principle is provided below in the recent accounting pronouncements section. Changes Affecting Comparability For the year ended December 31, 2021, the Company broke out “gains (losses), net on equity securities” that was previously reported in other non-interest income. As a result, changes within the Consolidated Statements of Income in the prior periods were made to conform to the current period presentation. The change provides additional detail about the Company’s operations. The changes had no impact on net income. For the year ended December 31, 2021, the Company consolidated the “Goodwill and other intangible assets, net” into “other assets” within the Consolidated Balance Sheets. The consolidation was due to the immateriality of the remaining intangible assets. The change had no impact on net income. Operating Segments An operating segment is a component of an entity that has separate financial information related to its business activities and is reviewed by the chief operating decision maker on a regular basis to allocate resources and assess performance. The Company identifies the following markets as operating segments: (i) Kansas City, Missouri and Leawood, Kansas; (ii) Wichita, Kansas; (iii) Oklahoma City, Oklahoma; (iv) Tulsa, Oklahoma; (v) Energy bank; (vi) Dallas and Frisco, Texas; and (vii) Phoenix, Arizona. These markets provide similar products and services using a similar process to a similar customer base. Our products and services include, but are not limited to, loans; checking and savings accounts; time deposits and credit cards. Loan products include commercial, real estate, consumer, and Small Business Administration (“SBA”) lending. The regulatory environment is the same for the markets as well. The chief operating decision maker monitors the revenue and costs of the markets; however, operations are managed, including allocation of resources, and financial performance is evaluated on a Company-wide basis. As a result, the markets are aggregated into one reportable segment. Cash Equivalents The Company considers all liquid investments with original maturities of three months or less to be cash equivalents. At December 31, 2021, cash equivalents consisted primarily of both interest-bearing and noninterest bearing accounts with other banks. Approximately $ 417 million of the Company’s cash and cash equivalents were held at the Federal Reserve Bank of Kansas City at December 31, 2021. The Company is required to maintain reserve funds in cash and/or on deposit with the Federal Reserve Bank. The reserve required at December 31, 2021 was $ 0 . In addition, the Company is required from time to time to place cash collateral with third parties as part of its back-to-back swap agreements and cash flow hedges. At December 31, 2021, $ 17 million was required as cash collateral. At December 31, 2021, the Company’s cash accounts, excluding funds at the Federal Reserve Bank and funds required as cash collateral, exceeded federally insured limits by $ 35 million. Securities Debt securities for which the Company has no immediate plan to sell but which may be sold in the future, are classified as available-for-sale (“AFS”) and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Gains and losses on the sale of debt securities are recorded on the trade date and are determined using the specific identification method. Equity securities are recorded at fair value with unrealized gains and losses included in earnings. Gains and losses on the sale of equity securities are recorded on the trade date and are determined using the specific identification method. The Company elected a measurement alternative for two equity investment s that did not have a readily determinable fair value and did not qualify for the practical expedient to estimate fair value using the net asset value per share. A cost basis was calculated for the equity investments. The recorded balance will adjust for any impairment or any observable price changes for an identical or similar investment of the same issuer. The Company routinely conducts periodic reviews to identify and evaluate each debt security to determine whether an OTTI has occurred. For available-for-sale securities that management has no intent to sell and believes that it more likely than not will not be required to sell prior to recovery, only the credit loss component of the impairment is recognized in earnings, while the noncredit loss is recognized in accumulated other comprehensive income. The credit loss component recognized in earnings is identified as the amount of principal cash flows not expected to be received over the remaining term of the security as projected based on cash flow projections. Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their outstanding principal balances adjusted for unearned income, charge-offs, the allowance for loan losses, any unamortized deferred fees or costs on originated loans and unamortized premiums or discounts on purchased loans. For loans amortized at cost, interest income is accrued based on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, as well as premiums and discounts, are deferred and amortized as a level yield adjustment over the respective term of the loan. Nonperforming Loans Nonperforming loans are loans for which we do not accrue interest income. The accrual of interest on mortgage and commercial loans is discontinued at the time the loan is 90 days past due unless the credit is well secured and in process of collection. A credit is considered well secured if it is secured by collateral in the form of liens or pledges of real or personal property, including securities, that have a realizable value sufficient to discharge the debt (including accrued interest) in full or is secured by the guaranty of a financially responsible party. A debt is in the process of collection if collection of the debt is proceeding in due course either through legal action, including enforcement procedures, or in appropriate circumstances, through collection efforts not involving legal action which are reasonably expected to result in repayment of the debt or in its restoration to a current status. Past due status is based on contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged off at an earlier date, if collection of principal or interest is considered doubtful. All interest accrued but not collected for loans that are placed on nonaccrual or charged off are reversed against interest income. The interest on these loans is accounted for on the cash basis or cost recovery method, until qualifying for return to accrual. When payments are received on nonaccrual loans, payments are applied to principal unless there is a clear indication that the quality of the loan has improved to the point that it can be placed back on accrual status. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Allowance for Loan Losses The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to income. Loan losses are charged against the allowance when management believes the loan balance is not collectible. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of its ability to collect the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The allowance consists of allocated and general components. The allocated component relates to loans that are individually classified as impaired. For those loans that are classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers the remaining pool of loans and is based on historical charge-off experience and expected loss given default derived from the Company’s internal risk rating process. Other adjustments may be made to the allowance for pools of loans after an assessment of internal or external influences on credit quality that are not fully reflected in the historical loss or risk rating data. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on an individual loan basis by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price or the fair value of the collateral, if the loan is collateral dependent. Groups of loans with similar risk characteristics are collectively evaluated for impairment based on the group’s historical loss experience adjusted for changes in trends, conditions and other relevant factors that affect repayment of the loans. Premises and Equipment Depreciable assets are stated at cost less accumulated depreciation. Depreciation is charged to expense using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are capitalized and depreciated using the straight-line method over the terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter. Expected terms include lease option periods to the extent that the exercise of such options is reasonably assured. The estimated useful lives for each major depreciable classification of premises and equipment are as follows: Long-Lived Asset Impairment The Company evaluates the recoverability of the carrying value of long-lived assets whenever events or circumstances indicate the carrying amount may not be recoverable. If a long-lived asset is tested for recoverability and the undiscounted estimated future cash flows expected to result from the use and eventual disposition of the asset is less than the carrying amount of the asset, the asset cost is adjusted to fair value and an impairment loss is recognized as the amount by which the carrying amount of a long-lived asset exceeds its fair value. Restricted Equity Securities Restricted equity securities include investments in FHLB Topeka and Bankers’ Bank of Kansas. FHLB Topeka is a Federal Home Loan Bank and its stock is a required investment for institutions that are members of the Federal Home Loan System. The required investment in the common stock is based on a predetermined formula. The Bankers’ Bank of Kansas is a correspondent bank located in Wichita, Kansas and the investment is carried at cost and evaluated for impairment. Bank-Owned Life Insurance The Company has purchased life insurance policies on certain key employees that are accounted for under the fair value method. Bank-owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value. Changes in cash surrender value are recorded in earnings in the period in which the changes occur. Foreclosed Assets Held-for-Sale Assets acquired through, or in lieu of, loan foreclosure are held-for-sale and are initially recorded at fair value less cost to sell at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less cost to sell. Revenue and expenses from operations and changes in the valuation allowance are included in net income or expenses from foreclosed assets. Goodwill Goodwill was evaluated annually for impairment or more frequently if impairment indicators were present. A qualitative assessment was performed to determine whether the existence of events or circumstances led to a determination that it was more likely than not the fair value was less than the carrying amount, including goodwill. If, based on the evaluation, it was determined to be more likely than not that the fair value was less than the carrying value, then goodwill was tested further for impairment. If the implied fair value of goodwill was lower than its carrying amount, a goodwill impairment was indicated and goodwill was written down to its implied fair value. Core Deposit Intangible The core deposit intangible represents the identified intangible asset relating to the deposit relationships acquired in past business combinations. The value of the core deposit intangible is based primarily upon the expected future benefits of earnings capacity attributable to those deposits. Related Party Transactions The Company extends credit and receives deposits from related parties. In management’s opinion, the loans and deposits were made in the ordinary course of business and made on similar terms as those prevailing at the time with other persons. Related party loans totaled $ 8 million and $ 16 million at December 31, 2021 and 2020, respectively. Related party deposits totaled $ 74 million and $ 55 million at December 31, 2021 and 2020, respectively. Stock-Based Compensation The Company accounts for all stock-based compensation transactions in accordance with Accounting Standard Codification (“ASC”) 718, Compensation - Stock Compensation, which requires that stock compensation transactions be recognized as compensation expense in the consolidated statement of income based on their fair values on the measurement date. The Company recognizes forfeitures as they occur. New shares are issued upon exercise of an award. The Company records permanent tax differences through the income tax provision upon vesting or exercise of a stock-based award. The various stock-based compensation plans are described more fully in Note 16: Stock-Based Compensation . Transfers of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when: (i) the assets have been isolated from the Company and put presumptively beyond the reach of the transferor and its creditors, even in bankruptcy or other receivership; (ii) 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 (iii) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets. Income Taxes The Company accounts for income taxes in accordance with income tax accounting guidance (ASC 740, Income Taxes). The income tax accounting guidance results in two components of income tax expense: (i) current; and (ii) deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over revenues. The Company determines deferred income taxes using the liability or balance sheet method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities and enacted changes in tax rates and laws are recognized in the period in which they occur. Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term, more likely than not, means a likelihood of more than 50 percent; the terms examined and upon examination also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more likely than not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more likely than not recognition threshold considers the facts, circumstances and information available at the reporting date and is subject to management’s judgment. Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized. The Company recognizes interest and penalties on income taxes as a component of income tax expense. The Company files consolidated income tax returns with its subsidiaries. Due to the carry forward of federal net operating losses, all prior years remain subject to examination by federal tax authorities. Earnings Per Share Basic earnings per share represent net income available to common stockholders divided by the weighted average number of common shares outstanding during each period. Diluted earnings per share reflect additional potential shares that would have been outstanding if dilutive potential common stock had been issued, as well as any adjustment to income that would result from the assumed issuance. Potential common stock that may be issued by the Company is determined using the treasury stock method. Fair Values of Financial Instruments The Company follows the applicable accounting guidance for fair value measurements and disclosures for all applicable financial and nonfinancial assets and liabilities. ASC 820, Fair Value Measurements and Disclosures (“ASC 820”), defines fair value, establishes a framework for measuring fair value under GAAP and enhances disclosures about fair value measurements. The Company values financial instruments based upon quoted market prices, where available. If market prices are not available, fair value is based on pricing models that use available information including quoted prices for similar assets or liabilities in active markets, market indicators, and industry and economic events. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Comprehensive Income Comprehensive income consists of net income and other comprehensive income, net of applicable income taxes. Other comprehensive income includes unrealized appreciation (depreciation) on available-for-sale securities and cash flow hedges. Derivative Financial Instruments ASC 815, Derivatives and Hedging, provides the disclosure requirements for derivatives and hedging activities with the intent to provide users of financial statements with an enhanced understanding of: (i) how and why an entity uses derivative instruments; (ii) how the entity accounts for derivative instruments and related hedged items; and (iii) how derivative instruments and related hedged items affect an entity’s financial position, financial performance, and cash flows. Further, qualitative disclosures are required that explain the Company’s objectives and strategies for using derivatives, as well as quantitative disclosures about the fair value of and gains and losses on derivative instruments, and disclosures about credit risk related contingent features in derivative instruments. As required by ASC 815, the Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the 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. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. In accordance with the Financial Accounting Standards Board's (“FASB”) fair value measurement guidance in ASU 2011-04, the Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counter-party portfolio. Emerging Growth Company (“EGC”) The Company is currently an EGC. An EGC may take advantage of reduced reporting requirements and is relieved of certain other significant requirements that are otherwise generally applicable to public companies. Among the reductions and reliefs, the Company elected to extend the transition period for complying with new or revised accounting standards affecting public companies. This means that the financial statements the Company files or furnishes, will not be subject to all new or revised accounting standards generally applicable to public companies for the transition period for so long as the Company remains an EGC or until the Company affirmatively and irrevocably opts out of the extended transition period under the JOBS Act. Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) The CARES Act and extended by the Consolidated Appropriations Act of 2021 allowed financial institutions to elect not to consider whether loan modifications relating to the COVID-19 pandemic that they make between March 1, 2020 and December 31, 2021 were troubled debt restructurings (“TDRs”), which required additional disclosures. The relief was applied to modifications of loans to borrowers that were not more than 30 days past due as of December 31, 2019 and were impacted by COVID-19. The Company elected to apply the guidance during the first quarter of 2020. The review of loans that met the criteria was overseen by the Office of the Chief Credit Officer and his team.

(2) Yields are calculated based on amortized cost using a 30/360 day basis. Tax-exempt securities are not tax effected. Gross Unrealized Losses Certain investments in AFS securities are reported in the consolidated financial statements at an amount less than their historical cost. Total fair value of these investments at December 31, 2021 and 2020, was $ 162 million and $ 18 million, which was approximately 22 % and 3 %, respectively, of the Company’s available-for-sale security portfolio. The unrealized losses on the Company’s investments in state and political subdivisions were caused by interest rate changes. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost basis of the investments. The unrealized losses on the Company’s investments in collateralized mortgage-backed securities and obligations were caused by interest rate changes and market assumptions about prepayment speeds. The Company expects to recover the amortized cost basis over the term of the securities. Because the Company does not intend to sell the investments and it is not more likely than not the Company will be required to sell the investments before recovery of their amortized cost basis, which may be maturity, the Company does not consider those investments to be OTTI at December 31, 2021. Based on evaluation of available evidence, including recent changes in market interest rates, credit rating information and information obtained from regulatory filings, management believes the declines in fair value for these securities are temporary. The following table shows available-for-sale securities gross unrealized losses, the number of securities that are in an unrealized loss position, and fair value of the Company’s investments with unrealized losses that are not deemed to be OTTI, aggregated by investment class and length of time that individual securities have been in a continuous unrealized loss position at December 31, 2021 and 2020: December 31, 2021 Less than 12 Months 12 Months or More Total Fair Value Unrealized Losses Number of Securities Fair Value Unrealized Losses Number of Securities Fair Value Unrealized Losses Number of Securities (Dollars in thousands) Available-for-Sale Securities Mortgage-backed - GSE residential $ 87,306 $ 1,774 16 $ — $ — — $ 87,306 $ 1,774 16 Collateralized mortgage obligations - GSE residential 803 10 2 — — — 803 10 2 State and political subdivisions 72,915 762 39 1,310 5 4 74,225 767 43 Corporate bonds — — — — — — — — — Total temporarily impaired AFS securities $ 161,024 $ 2,546 57 $ 1,310 $ 5 4 $ 162,334 $ 2,551 61 December 31, 2020 Less than 12 Months 12 Months or More Total Fair Value Unrealized Losses Number of Securities Fair Value Unrealized Losses Number of Securities Fair Value Unrealized Losses Number of Securities (Dollars in thousands) Available-for-Sale Securities Mortgage-backed - GSE residential $ — $ — — $ — $ — — $ — $ — — Collateralized mortgage obligations - GSE residential 9,933 42 5 — — — 9,933 42 5 State and political subdivisions 8,525 31 8 25 — 1 8,550 31 9 Corporate bonds — — — — — — — — — Total temporarily impaired AFS securities $ 18,458 $ 73 13 $ 25 $ — 1 $ 18,483 $ 73 14 Other-Than-Temporary Impairment Upon acquisition of a security, the Company decides whether it is within the scope of the accounting guidance for beneficial interests in securitized financial assets or will be evaluated for impairment under the accounting guidance for investments. The accounting guidance for beneficial interests in securitized financial assets provides incremental impairment guidance for a subset of the securities within the scope of the guidance. For securities where the security is a beneficial interest in securitized financial assets, the Company uses the beneficial interests in securitized financial asset impairment model. For securities where the security is not a beneficial interest in securitized financial assets, the Company uses the securities impairment model. The Company routinely conducts periodic reviews to identify and evaluate each investment security to determine whether an OTTI has occurred. Economic models are used to determine whether an OTTI has occurred on these securities. The Company recorded no OTTI losses on AFS securities in 2021, 2020 or 2019. Equity Securities Equity securities consist of a $ 2 million investment in Community Reinvestment Act (“CRA”) mutual fund and a $ 433 thousand private equity investment. Equity securities are included in other assets on the Consolidated Balance Sheets. During 2020, the Company acquired an $ 11 million privately-held security in partial satisfaction of debts previously contracted. The Company used a discounted cash flow model, a market transactions model and a public valuation approach to determine the security’s cost basis. The Company elected a measurement alternative that allows the security to remain at cost until an impairment is identified or an observable price change for an identical or similar investment of the same issuer occurs. Impairment is recorded when there is evidence that the expected fair value of the investment has declined to below the recorded cost. No changes to the cost basis occurred in 2020. During 2021, the Company sold the equity security for $ 5 million that resulted in a $ 6 million realized loss. The following is a summary of the recorded fair value and the unrealized and realized gains and losses recognized in net income on equity securities: For the Year Ended December 31, 2021 2020 2019 (Dollars in thousands) Net gains (losses) recognized during the reporting period on equity securities $ (6,325) $ 46 $ 62 Less: net losses recognized during the period on equity securities sold during the period (6,245) — — Unrealized gain (loss) recognized during the reporting period on equity securities still held at the reporting date $ (80) $ 46 $ 62

Note 4: Loans and Allowance for Loan Losses Categories of loans at December 31, 2021 and 2020 include: The following tables summarize the activity in the allowance for loan losses by portfolio segment and disaggregated based on the Company’s impairment methodology. The allocation in one portfolio segment does not preclude its availability to absorb losses in other segments: Credit Risk Profile The Company analyzes its loan portfolio based on internal rating categories (grades 1 - 8), portfolio segmentation and payment activity. These categories are utilized to develop the associated ALLL. A description of the loan grades and segments follows: Loan Grades • Pass (risk rating 1-4) - Considered satisfactory. Includes borrowers that generally maintain good liquidity and financial condition or the credit is currently protected with sales trends remaining flat or declining. Most ratios compare favorably with industry norms and Company policies. Debt is programmed and timely repayment is expected. • Special Mention (risk rating 5) - Borrowers generally exhibit adverse trends in operations or an imbalanced position in their balance sheet that has not reached a point where repayment is jeopardized. Credits are currently protected but, if left uncorrected, the potential weaknesses may result in deterioration of the repayment prospects for the credit or in the Company’s credit or lien position at a future date. These credits are not adversely classified and do not expose the Company to enough risk to warrant adverse classification. • Substandard (risk rating 6) - Credits generally exhibit well-defined weakness(es) that jeopardize repayment. Credits are inadequately protected by the current worth and paying capacity of the obligor or of the collateral pledged. A distinct possibility exists that the Company will sustain some loss if deficiencies are not corrected. Loss potential, while existing in the aggregate amount of substandard assets, does not have to exist in individual assets classified substandard. Substandard loans include both performing and nonperforming loans and are broken out in the table below. • Doubtful (risk rating 7) - Credits which exhibit weaknesses inherent in a substandard credit with the added characteristic that these weaknesses make collection or liquidation in full highly questionable or improbable based on existing facts, conditions and values. Because of reasonably specific pending factors, which may work to the advantage and strengthening of the assets, classification as a loss is deferred until its more exact status may be determined. • Loss (risk rating 8) - Credits which are considered uncollectible or of such little value that their continuance as a bankable asset is not warranted. Loan Portfolio Segments • Commercial - Includes loans to commercial customers for use in financing working capital, equipment purchases and expansions. Repayment is primarily from the cash flow of a borrower’s principal business operation. Credit risk is driven by creditworthiness of a borrower and the economic conditions that impact the cash flow stability from business operations. • Energy - Includes loans to oil and natural gas customers for use in financing working capital needs, exploration and production activities, and acquisitions. The loans are repaid primarily from the conversion of crude oil and natural gas to cash. Credit risk is driven by creditworthiness of a borrower and the economic conditions that impact the cash flow stability from business operations. Energy loans are typically collateralized with the underlying oil and gas reserves. • Commercial Real Estate - Loans typically involve larger principal amounts, and repayment of these loans is generally dependent on the successful operations of the property securing the loan or the business conducted on the property securing the loan. These are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Credit risk may be impacted by the creditworthiness of a borrower, property values and the local economies in the borrower’s market areas. • Construction and Land Development - Loans are usually based upon estimates of costs and estimated value of the completed project and include independent appraisal reviews and a financial analysis of the developers and property owners. Sources of repayment include permanent loans, sales of developed property or an interim loan commitment from the Company until permanent financing is obtained. These loans are higher risk than other real estate loans due to their ultimate repayment being sensitive to interest rate changes, general economic conditions and the availability of long-term financing. Credit risk may be impacted by the creditworthiness of a borrower, property values and the local economies in the borrower’s market areas. • Residential and Multifamily Real Estate - The loans are generally secured by owner-occupied 1-4 family residences or multifamily properties. Repayment of these loans is primarily dependent on the personal income and credit rating of the borrowers or underlying tenants. Credit risk in these loans can be impacted by economic conditions within or outside the borrower’s market areas that might impact either property values, a borrower’s personal income, or residents’ income. • PPP - The loans were established by the CARES Act which authorized forgivable loans to small businesses to pay their employees during the COVID-19 pandemic. The program requires all loan terms to be the same for everyone. The loans are 100% guaranteed by the SBA and repayment is primarily dependent on the borrower’s cash flow or SBA repayment approval. • Consumer - The loan portfolio consists of revolving lines of credit and various term loans such as automobile loans and loans for other personal purposes. Repayment is primarily dependent on the personal income and credit rating of the borrowers. Credit risk is driven by consumer economic factors (such as unemployment and general economic conditions in the borrower’s market area) and the creditworthiness of a borrower. Loans by Risk Rating The following tables present the credit risk profile of the Company’s loan portfolio based on an internal rating category and portfolio segment: Loan Portfolio Aging Analysis The following tables present the Company’s loan portfolio aging analysis of the recorded investment in loans as of December 31, 2021 and 2020: Impaired Loans A loan is considered impaired, in accordance with the impairment accounting guidance (ASC 310-10-35-16), when based on current information and events, it is probable the Company will be unable to collect all amounts due from the borrower in accordance with the contractual terms of the loan. Impaired loans include nonperforming loans but also include loans modified in troubled debt restructurings where concessions have been granted to borrowers experiencing financial difficulties. The intent of concessions is to maximize collection. Groups of loans with similar risk characteristics are collectively evaluated for impairment based on the group’s historical loss experience adjusted for changes in trends, conditions and other relevant factors that affect repayment of the loans. The following tables present loans individually evaluated for impairment, including all restructured and formerly restructured loans, for the periods ended December 31, 2021 and December 31, 2020: Non-accrual Loans Non-accrual loans are loans for which the Company does not record interest income. The accrual of interest on loans is discontinued at the time the loan is 90 days past due unless the credit is well secured and in process of collection. Past due status is based on contractual terms of the loan. In all cases, loans are placed on non-accrual or charged off at an earlier date, if collection of principal or interest is considered doubtful. All interest accrued but not collected for loans that are placed on non-accrual or charged off are reversed against interest income. The interest on these loans is accounted for on the cash basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. The following table presents the Company’s non-accrual loans by loan category at December 31, 2021 and 2020: Troubled Debt Restructurings (“TDR”) Restructured loans are those extended to borrowers who are experiencing financial difficulty and who have been granted a concession, excluding loan modifications as a result of the COVID-19 pandemic as permitted by the CARES Act (as extended by the Consolidated Appropriations Act of 2021). A TDR may also exist if the borrower transfers to the Bank: (i) receivables for third parties; (ii) real estate; (iii) other assets; or (iv) an equity position in the borrower to fully or partially satisfy a loan or the issuance or other granting of an equity position to the Bank to fully or partially satisfy a debt unless the equity position is granted pursuant to existing terms for converting the debt into an equity position. Once an obligation has been restructured, the loan continues to be considered restructured until: (i) the obligation is paid in full or (ii) the borrower is in compliance with its modified terms for at least 12 consecutive months, the loan has a market rate, and the borrower could obtain similar terms from another bank. When a loan undergoes a TDR, the determination of whether the loan would remain on accrual status depends on several factors including: (i) the accrual status prior to the restructuring; (ii) the borrower’s demonstrated performance under the previous terms; and (iii) the Bank’s credit evaluation of the borrower’s capacity to continue to perform under the restructured terms. Loans identified as TDRs are evaluated for impairment using the present value of the expected cash flows or the estimated fair value of the collateral if the loan is collateral dependent. The fair value is determined, when possible, by an appraisal of the property less estimated costs related to liquidation of the collateral. The appraisal amount may also be adjusted for current market conditions. Adjustments to reflect the present value of the expected cash flows or the estimated fair value of collateral dependent loans are a component in determining an appropriate allowance, and as such, may result in increases or decreases to the provision for loan losses in current and future earnings. The table below presents loans restructured during the years ended December 31, 2021 and 2020, including the post-modification outstanding balance and the type of concession made: As of December 31, 2021, the modifications related to the troubled debt restructurings above did not impact the allowance for loan losses because the loans were previously impaired and evaluated on an individual basis or sufficient collateral was obtained. For the year ended December 31, 2021 and 2020, the TDRs outstanding resulted in charge-offs of $ 0 and $ 26 million and recoveries of $ 81 thousand and $ 0 , respectively. No TDRs modified within the past 12 months defaulted in 2021. The restructured loans had a total specific valuation allowance of $ 4 million as of December 31, 2021 and 2020, respectively. The balance of restructured loans and the balance of those loans that are in default at any time during the past 12 months at December 31, 2021 and 2020 is provided below: During the year ended December 31, 2021, $ 2 million of interest income was recognized related to the $ 40 million in TDRs above. If the loans had been current in accordance with their original terms and had been outstanding throughout the period or since inception, the gross interest income that would have been recorded for the year ended December 31, 2021 would have been $ 3 million. During the year ended December 31, 2020, $ 1 million of interest income was recognized related to the $ 63 million in TDRs above. If the loans had been current in accordance with their original terms and had been outstanding throughout the period or since inception, the gross interest income that would have been recorded for the year ended December 31, 2020 would have been $ 2 million.

Goodwill and Core Deposit Intangible [Abstract]
Goodwill and Core Deposit Intangible	Note 6: Goodwill and Core Deposit Intangible As a result of economic conditions from the COVID-19 pandemic and oil market volatility, the Company conducted a June 30, 2020 goodwill impairment test. The test required a goodwill impairment charge of $ 7 million, representing full impairment of goodwill. The primary causes of the goodwill impairment were economic conditions, volatility in the market capitalization of the Company, increased loan provision in light of the COVID-19 pandemic, and other changes in key variables driven by the uncertain macro-environment that when combined, resulted in the reporting unit’s fair value being less than the carrying value. The Tulsa, Oklahoma market represented the reporting unit and included all goodwill previously recorded. The reporting unit’s fair value was determined using a combination of: (i) the capitalization of earnings method, an income approach, and (ii) the public company method, a market approach. The income approach estimated fair value by determining the cash flow in a single period, adjusted for growth that is adjusted by a capitalization rate. The market approach estimated fair value by averaging the price-to-book multiples from peer, public banks and adding a control premium. Since the core deposit intangible (“CDI”) outstanding came from the same reporting unit, the Company conducted an impairment test of CDI as of June 30, 2020. The Company used an income approach to calculate a CDI fair market value. The results indicated the CDI was not impaired as of June 30, 2020. Following the June 30, 2020 impairment test, no additional qualitative factors arose requiring us to perform another CDI impairment test. Fair value determinations require considerable judgment and are sensitive to changes in underlying assumptions, estimates, and market factors. Estimating the fair value of individual reporting units requires management to make assumptions and estimates regarding the Company’s future plans, as well as industry, economic, and regulatory conditions. These assumptions and estimates include estimated future cash flows, income tax rates, discount rates, growth rates, and other market factors. The change in goodwill and core deposit intangible during the years ended December 31, 2021 and 2020 were: Gross Carrying Amount Accumulated Amortization Impairment Net Carrying Amount (Dollars in thousands) December 31, 2021 Core deposit intangible 1,014 884 — 130 Total goodwill and intangible assets $ 1,014 $ 884 $ — $ 130 December 31, 2020 Goodwill $ 7,397 $ — $ 7,397 $ — Core deposit intangible 1,014 806 — 208 Total goodwill and intangible assets $ 8,411 $ 806 $ 7,397 $ 208 The remaining CDI balance will amortize over the next two years .

Derivatives and Hedging Activities	12 Months Ended
Derivatives and Hedging Activities	Dec. 31, 2021
Derivatives and Hedging Activities [Abstract]
Derivatives and Hedging Activities	Note 7: Derivatives and Hedging Activities Risk Management Objective of Using Derivatives The Company is exposed to certain risk arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of its assets and liabilities and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. Cash Flow Hedges of Interest Rate Risk The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily 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 variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. During 2021, the Company entered into forward-looking derivatives that will be used to hedge variable cash flows associated with variable-rate funding. These 5 swaps had an aggregate notional amount of $ 100 million and $ 0 at December 31, 2021 and 2020, respectively. 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 (“AOCI”) and subsequently reclassified into interest expense in the same period(s) during which the hedged transaction affects earnings. Amounts reported in AOCI related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s related, variable-rate debt. During the next twelve months, the Company estimates that an additional $ 0 will be reclassified as a reduction to interest expense. The Company’s derivative financial instruments are not effective until 2023. As a result, the derivative financial instruments did not impact the Income Statement for the year ended December 31, 2021 and 2020. Non-designated Hedges Derivatives not designated as hedges are not speculative and result from a service provided to clients. The Company executes interest rate swaps with customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously hedged by offsetting derivatives that the Company executes with a third-party, such that the Company minimizes its net risk exposure resulting from such transactions. Interest rate derivatives associated with this program do not meet the strict hedge accounting requirements and changes in the fair value of both the customer derivatives and the offsetting derivatives are recognized directly in earnings. These 54 and 56 swaps had an aggregate notional amount of $ 535 million and $ 516 million at December 31, 2021 and 2020, respectively. During 2019, the Company changed an input associated with the fair market value related to derivatives not designated as hedges. The model utilized to calculate the nonperformance risk, also known as the credit valuation adjustment (“CVA”), was adjusted from a default methodology to an internal review process by the Company. Management believes this change better aligns with the Company’s credit methodology and underwriting standards. As a result of the change in methodology, the Company recorded an adjustment to increase swap fee income, net, by approximately $ 800 thousand, related to swaps closed as of June 30, 2019. If no defaults occur for derivatives not designated as hedges, the change in methodology will lower future swap fee income, net, by the same amount. The effect of the Company’s derivative financial instruments that are not designated as hedging instruments are reported on the statements of income as swap fee income, net. During 2021, the Company recorded a $ 342 thousand gain for CVA adjustments primarily related to one swap. During 2020, the Company recorded a $ 290 thousand loss for CVA adjustments primarily related to one swap. The effect of the Company’s derivative financial instruments gain or loss are reported on the statements of cash flows within other assets and other liabilities. Fair Values of Derivative Instruments on the Balance Sheet The table below presents the fair value of the Company’s derivative financial instruments and their classification on the balance sheet as of December 31, 2021 and 2020: Asset Derivatives Liability Derivatives Balance Sheet As of December 31, Balance Sheet As of December 31, Location 2021 2020 Location 2021 2020 (Dollars in thousands) Interest rate products: Derivatives designated as hedging instruments Other assets $ 3 $ — Other liabilities $ 565 $ — Derivatives not designated as hedging instruments Other assets $ 11,305 $ 24,094 Other liabilities $ 11,322 $ 24,454 Total $ 11,308 $ 24,094 $ 11,887 $ 24,454 Effect of Cash Flow Hedge Accounting on Accumulated Other Comprehensive Income The table below presents the effect of cash flow hedge accounting on Accumulated Other Comprehensive Income as of December 31, 2021.

During 2020, the Company sold the industrial facilities that were foreclosed upon in 2019 and impaired the raw land foreclosed upon in 2019. Upon acquisition, foreclosed assets are recorded at fair value less estimated selling costs at the date of foreclosure, establishing a new cost basis. They are subsequently carried at the lower of cost or fair value less estimated selling costs. Income and losses are reported on the Consolidated Statements of Income under the foreclosed assets, net section.

Interest-bearing Time Deposits	Note 9: Interest-bearing Time Deposits Interest-bearing time deposits in denominations of $250 thousand or more were $ 324 million and $ 524 million as of December 31, 2021 and 2020, respectively. The Company acquires brokered deposits in the normal course of business. At December 31, 2021 and 2020, brokered deposits of approximately $ 91 million and $ 188 million, respectively, were included in the Company’s time deposit balance. Reciprocal deposits, which includes The Certificate of Deposit Account Registry Services (“CDARS”) discussed below, are treated as core deposits instead of brokered deposits and are not included in the above amounts. The Company is a member of CDARS that allows depositors to receive FDIC insurance on amounts greater than the FDIC insurance limit, which is currently $250,000. CDARS allows institutions to break large deposits into smaller amounts and place them in a network of other CDARS institutions to ensure full FDIC insurance is gained on the entire deposit. CDARS totaled approximately $ 50 million and $ 75 million as of December 31, 2021 and 2020, respectively. The scheduled maturities for time deposits are provided in Note 10: Borrowing Arrangements below.

The obligations are collateralized by securities of U.S. government sponsored enterprises and mortgage-backed securities and such collateral is held by a third-party custodian. The year-to-date average daily balance was $ 2 million and $ 32 million for the years ended December 31, 2021 and 2020, respectively. The securities, mortgage-backed government sponsored residential securities, pledged for customer repurchase agreements were $ 0 and $ 6 million at December 31, 2021 and 2020, respectively. (2) Federal funds purchased include short-term funds that are borrowed from another bank. The Bank is part of a third-party service that allows us to borrow amounts from another bank if the bank has approved us for credit. Federal funds purchased generally have one day maturities. (3) FHLB advances and line of credit are collateralized by a blanket floating lien on certain loans, as well as, unrestricted securities. FHLB advances are at a fixed rate, ranging from 0.37 % to 2.88 % and are subject to restrictions or penalties in the event of prepayment. The FHLB line of credit has a variable interest rate that reprices daily based on FHLB’s cost of funds and matures on May 14, 2022. (4) Federal Reserve borrowings are collateralized by certain available-for-sale securities and certain loans. The Federal Reserve discount window advance rates are variable and based on an established discount rate determined by the Reserve Banks’ board of directors, subject to review and determination by the Board of Governors. The borrowings typically mature in 90 days. (5) On June 30, 2010, the Company assumed a liability with a fair value of $ 1 million related to the assumption of trust preferred securities issued by Leawood Bancshares Statutory Trust I for $ 4 million on September 30, 2005. In 2012, the Company settled litigation related to the trust preferred securities which decreased the principal balance by $ 1.5 million and the recorded balance by approximately $ 400 thousand. The difference between the recorded amount and the contract value of $ 2.5 million is being accreted to the maturity date in 2035. Distributions will be paid on each security at a variable annual rate of interest, equal to LIBOR, plus 1.74 %. (6) Represents the year-end weighted average interest rate. The following table summarizes the Company’s other borrowing capacities at December 31, 2021 and 2020: The scheduled maturities, excluding interest, of the Company’s borrowings at December 31, 2021 were as follows: (1) The contract value of the trust preferred securities is $ 2.6 million and is currently being accreted to the maturity date of 2035. During the year ended December 31, 2021, the Company recorded $ 771 thousand in prepayment penalties related to $ 40 million of FHLB borrowings. The prepayment penalties are included in interest expense within the Consolidated Statements of Income.

The Basel III Capital Rules (“Basel III”) were jointly published by three federal banking regulatory agencies. Basel III defines the components of capital, risk weighting and other issues affecting the numerator and denominator in regulatory capital ratios. 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. The actions may include dividend payment restrictions, require the adoption of remedial measures to increase capital, terminate FDIC deposit insurance, and mandate the appointment of a conservator or receiver in severe cases. 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 U.S. GAAP, regulatory reporting requirements and regulatory capital standards. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Furthermore, the Company’s regulators could require adjustments to regulatory capital not reflected in these consolidated financial statements. 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 and tier I capital (as defined) to risk-weighted assets (as defined), common equity tier I capital (as defined) to risk-weighted assets (as defined), and of tier I capital (as defined) to average assets (as defined). Management believes, as of December 31, 2021, the Company and the Bank met all capital adequacy requirements to which they are subject. As of December 31, 2021, the most recent notification from the applicable regulatory agencies categorized the Bank 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, tier I risk-based, common equity tier I risk-based and tier I leverage ratios as set forth in the table below. There are no conditions or events since that notification that management believes have changed the Bank’s category. The Company’s and the Bank’s actual capital amounts and ratios as of December 31, 2021 and 2020 are presented in the following table: The above minimum capital requirements include the capital conservation buffer required to avoid limitations on capital distributions, including dividend payments and certain discretionary bonus payments to executive officers. The capital conservation buffer was 2.5 % at December 31, 2021 and 2020.

Institutions include, but not are not limited to, finance company, insured depository institution, bank holding company, savings and loan association holding company, bank and savings institution not federally insured, mortgage company, foreign financial institution and credit union.

Revenue from Contracts with Customers	12 Months Ended
Revenue from Contracts with Customers	Dec. 31, 2021
Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customers	Note 15: Revenue from Contracts with Customers Except for gains or losses from the sale of foreclosed assets, the Company’s revenue from contracts with customers within the scope of ASC 606 is recognized in non-interest income. The revenue categories are selected based on the nature, amount, timing, and uncertainty of revenue and cash flows. The following presents descriptions of revenue categories within the scope of ASC 606: Service charges and fees (rebates) on customer accounts - This segment consists of monthly fees for the services rendered on customer deposit accounts, including maintenance charges, overdraft fees, and processing fees. The monthly fee structures are typically based on type of account, volume, and activity. The customer is typically billed monthly and pays the bill from their deposit account. The Company satisfies the performance obligation related to providing depository accounts monthly as transactions are processed and deposit service charge revenue is recorded. ATM and credit card interchange income - This segment consists of fees charged for use of the Company’s ATMs, as well as, an interchange fee with credit card and debit card service providers. ATM fees and interchange fees are based on the number of transactions, as well as, the underlying agreements. Customers are typically billed monthly. The Company satisfies the performance obligation related to ATM and interchange fees monthly as transactions are processed and revenue is recorded. International fees - This segment consists of fees earned from foreign exchange transactions and preparation of international documentation. International fees are based on underlying agreements that describe the Company’s performance obligation and the related fee. Customers are typically billed and cash is received once the service or transaction is complete. The Company satisfies the performance obligation related to international fees monthly as transactions are processed and revenue is recorded. Other fees - This segment consists of numerous, smaller fees such as wire transfer fees, referral fees, check cashing fees, and check printing fees. Other fees are typically billed to customers on a monthly basis. Performance obligations for other fees are satisfied at the time that the service is rendered. Gain or loss on foreclosed assets – Foreclosed assets are often sold in transactions that may not be considered a contract with a customer because the sale of the asset may not be an output of the Company’s ordinary activities. However, sales of nonfinancial assets, including in-substance nonfinancial assets, should be accounted for in accordance with ASC 610-20, “Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets,” which requires the Company to apply certain measurement and recognition concepts of ASC 606. Accordingly, the Company recognizes the sale of a foreclosed asset, along with any associated gain or loss, when control of the asset transfers to the buyer. For sales of existing assets, this generally will occur at the point of sale. When the Company finances the sale of the foreclosed asset to the buyer, the Company must assess whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the repossessed asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the asset to the buyer. The following table disaggregates the noninterest income subject to ASC 606 by category: For the Year Ended December 31, 2021 2020 2019 (Dollars in thousands) Non-interest income subject to ASC 606 Service charges and fees on customer accounts $ 4,580 $ 2,803 $ 604 ATM and credit card interchange income 7,996 4,379 1,785 International fees 1,531 1,091 716 Other fees 134 87 122 Total non-interest income from contracts with customers 14,241 8,360 3,227 Non-interest income not subject to ASC 606 Other non-interest income (581) 3,373 5,480 Total non-interest income $ 13,660 $ 11,733 $ 8,707

- Definition

In addition, the Company has an Employee Stock Purchase Plan (“ESPP”) that was suspended effective April 1, 2019 and reinstituted effective July 1, 2020. The Omnibus Plan will expire on the tenth anniversary of its effective date. The aggregate number of shares authorized for future issuance under the Omnibus Plan is 1,775,245 shares as of December 31, 2021. The Company will issue new common shares upon exercise or vesting of stock-based awards. During 2018, awards issued under the Stock Settled Appreciation Right (“SSAR”) Plan, Equity Incentive Plan, Employee Equity Incentive Plan and New Market Founder Plan were assumed under the Omnibus Plan as agreed upon with participants, impacting all participants who agreed to the assumption. The awards are called “Legacy Awards.” Material terms and conditions of Legacy Awards remain unchanged; therefore, no modification to their fair market value was required. Going forward, all awards will be issued under the Omnibus Plan. The table below summarizes stock-based compensation for the years ended December 31, 2021, 2020, and 2019: Stock Settled Appreciation Rights SSARs are granted based on the fair market value of the Company’s common stock. SSARs typically vest in equal amounts over a seven-year period, commencing on the first anniversary of the effective date of grant and have fifteen-year contractual terms for Legacy Awards and ten-year contractual terms for all other SSARs. Legacy Awards include retirement eligibility upon the participant’s 65th birthday, five years of participation, and after one year holding the grant. The exercise of a SSAR entitles the participant to the excess of the exercise price over the grant price for each SSAR. Exercise price is based on the fair market value of the Company’s common shares. The calculated value of each share award is estimated at the grant date using a Black-Scholes option valuation model. Expected volatility is primarily based on an internal model that calculates the historical volatility of the Company’s stock since the IPO and several peer group banks’ weekly average stock prices before the IPO over the expected term. The expected term of stock granted represents the period that shares are expected to be outstanding. The risk-free rate for periods within the contractual life of the share award is based on the U.S. Treasury yield curve. For the expected term, the Company uses the simplified method described in SAB Topic 14.D.2. This method uses an expected term based on the midpoint between the vesting date and the end of the contractual term. This method is used for the majority of SSARs, because the Company does not have a significant pool of SSARs that have been exercised. For some SSARs that are granted to participants who will be retirement eligible during the term of the award, a separate analysis is performed that focuses more on expected retirement date. The following table provides the range of assumptions used in the Black-Scholes valuation model, the weighted average grant date fair value, and information related to SSARs exercised for the following years, as well as, the remaining compensation cost to be recognized and period over which the amount will be recognized as of the dates indicated: A summary of SSAR activity during and as of December 31, 2021 is presented below: Performance-Based Stock Awards (“PBSAs”) The Company awards PBSAs to key officers of the Company. The stock settled awards are typically granted annually as determined by the Compensation Committee. The performance-based shares typically cliff-vest at the end of three years based on attainment of certain performance metrics developed by the Compensation Committee. The ultimate number of shares issuable under each performance award is the product of the award target and the award payout percentage given the level of achievement. The award payout percentages by level of achievement range between 0 % of target and 150 % of target. During 2016, the Company awarded PBSAs to New Market Founders. A New Market Founder is a nonemployee, adviser chosen in a selected market to facilitate expansion of banking relationships. During 2016, 116,960 PBSAs were granted and cliff-vested on December 31, 2021. The Company adopted ASU 2018-07 in the first quarter of 2019, which set the fair market value for this award. The Company determined that no substantial service existed for this award, resulting in a cumulative effect adjustment of approximately $ 2 million to retained earnings. The New Market Founder PBSAs were based upon four equally weighted market measures: total assets, total loans, return on assets and classified assets to capital as of December 31, 2021 that resulted in 139,709 common shares to be issued. The 119 % payout percentage resulted in $ 245 thousand of expense being recognized during the year-ended December 31, 2021. During the year-ended December 31, 2021, a former employee’s performance award vesting dates were accelerated and shares were issued at or slightly above target resulting in a $ 411 thousand increase in expense. During the year-ended December 31, 2021, 63,631 PBSAs were granted. The performance metrics included three year cumulative, adjusted earnings per share and relative total shareholder return. The following table summarizes the status of and changes in the performance-based awards: Unrecognized stock-based compensation expense related to the performance grants issued through December 31, 2021 was $ 661 thousand and is expected to be recognized over 2.1 years. Restricted Stock Units (“RSUs”) and Restricted Stock Awards (“RSAs”) The Company issues RSUs and RSAs to provide additional incentives to key officers, employees, and nonemployee directors. Awards are typically granted annually as determined by the Compensation Committee. The service based RSUs typically cliff-vest at the end of three years for Legacy Awards and vest in equal amounts over three years for all other RSUs. The service based RSAs typically cliff-vest after one year . As of December 31, 2021, no Legacy RSUs or RSAs remained outstanding. The following table summarizes the status of and changes in the RSUs and RSAs: Unrecognized stock-based compensation expense related to restricted stock grants issued through December 31, 2021 was $ 3 million and is expected to be recognized over 1.8 years. Employee Stock Purchase Plan The Company has an ESPP whereby employees are eligible for the plan when they have met certain requirements concerning period of credited service and minimum hours worked. The calculated value of each unit award is estimated at the start of the offering period using a Black-Scholes option valuation model that used the assumptions noted in the following table:

Disclosure about Fair Value of Financial Instruments [Abstract]
Disclosure about Fair Value of Financial Instruments	Level 1 Quoted prices in active markets for identical assets or liabilities Level 2 Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 Unobservable inputs supported by little or no market activity and significant to the fair value of the assets or liabilities. Fair Value Description Valuation Hierarchy Level Where Fair Value Balance Can Be Found Available-for- sale securities and equity security Where quoted market prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. If quoted market prices are not available, then fair values are estimated by using quoted prices of securities with similar characteristics or independent asset pricing services and pricing models, the inputs of which are market-based or independently sourced market parameters, including, but not limited to, yield curves, interest rates, volatilities, prepayments, defaults, cumulative loss projections and cash flows.

Fair value measurements must maximize the use of observable inputs and minimize the use of unobservable inputs. There is a hierarchy of three levels of inputs that may be used to measure fair value: Recurring Measurements The following list presents the assets and liabilities recognized in the accompanying consolidated Balance Sheets measured at fair value on a recurring basis and the level within the fair value hierarchy in which the fair value measurements fall at December 31, 2021 and 2020: Nonrecurring Measurements The following tables present the fair value measurement of assets measured at fair value on a nonrecurring basis and the level within the fair value hierarchy in which the fair value measurements fall: Following is a description of the valuation methodologies and inputs used for assets measured at fair value on a nonrecurring basis and recognized in the accompanying consolidated balance sheets, as well as the general classification of such assets pursuant to the valuation hierarchy. For assets classified within Level 3 of the fair value hierarchy, the process used to develop the reported fair value is described below. Collateral-Dependent Impaired Loans, Net of ALLL The estimated fair value of collateral-dependent impaired loans is based on the appraised fair value of the collateral, less estimated cost to sell. Collateral dependent impaired loans are classified within Level 3 of the fair value hierarchy. The Company considers the appraisal or evaluation as the starting point for determining fair value and then considers other factors and events in the environment that may affect the fair value. Appraisals of the collateral underlying collateral dependent loans are obtained when the loan is determined to be collateral-dependent and subsequently as deemed necessary by the Chief Credit Officer. Appraisals are reviewed for accuracy and consistency by the Chief Credit Officer. Appraisers are selected from the list of approved appraisers maintained by management. The appraised values are reduced by discounts to consider lack of marketability and estimated cost to sell if repayment or satisfaction of the loan is dependent on the sale of the collateral. These discounts and estimates are developed by the Chief Credit Officer by comparison to historical results. Foreclosed Assets Held-for-Sale The fair value of foreclosed assets held-for-sale is based on the appraised fair value of the collateral, less estimated cost to sell. Unobservable (Level 3) Inputs The following tables present quantitative information about unobservable inputs used in nonrecurring Level 3 fair value measurements at December 31, 2021 and 2020: See Note 16: Stock-Based Compensation for quantitative information about unobservable inputs used in the fair value measurement of stock appreciation rights. The following tables present the estimated fair values of the Company’s financial instruments at December 31, 2021 and 2020:

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Significant Estimates and Concentrations [Abstract]
Significant Estimates and Concentrations	Note 20: Significant Estimates and Concentrations GAAP requires disclosure of certain significant estimates and current vulnerabilities due to certain concentrations. Estimates related to the allowance for loan losses are reflected in Note 4: Loans and Allowance for Loan Losses . Current vulnerabilities due to certain concentrations of credit risk are discussed in Note 21: Commitments and Credit Risk . Credit risk related to derivatives is reflected in the Note 7: Derivatives and Hedging Activities . Estimates related to equity awards are reflected in Note 16: Stock-Based Compensation . Other significant estimates and concentrations not discussed in those footnotes include: Investments The Company invests in various investment securities. Investment securities are exposed to various risks such as interest rate, market and credit risk. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such change could materially affect the amounts reported in the accompanying consolidated balance sheets. General Litigation The Company is subject to claims and lawsuits that arise primarily in the ordinary course of business. It is the opinion of management that the disposition or ultimate resolution of such claims and lawsuits will not have a material adverse effect on the consolidated financial position, results of operations and cash flows of the Company.

Commitments and Credit Risk [Abstract]
Commitments and Credit Risk	Note 21: Commitments and Credit Risk The Company had the following commitments at December 31, 2021 and 2020: December 31, 2021 December 31, 2020 (Dollars in thousands) Commitments to originate loans $ 118,651 $ 99,596 Standby letters of credit 51,114 48,607 Lines of credit 1,768,231 1,423,038 Future lease commitments 11,100 — Commitment related to investment fund 2,067 — Total $ 1,951,163 $ 1,571,241 Commitments to Originate Loans Commitments to originate loans 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 a portion of the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Each customer’s creditworthiness is evaluated on a case by case basis. The amount of collateral obtained, if deemed necessary, is based on management’s credit evaluation of the counterparty. Collateral held varies, but may include accounts receivable, inventory, property, plant and equipment, commercial real estate and residential and multifamily real estate. Standby Letters of Credit Standby letters of credit are irrevocable conditional commitments issued by the Company to guarantee the performance of a customer to a third-party. Financial standby letters of credit are primarily issued to support public and private borrowing arrangements, including commercial paper, bond financing and similar transactions. Performance standby letters of credit are issued to guarantee performance of certain customers under nonfinancial contractual obligations. The credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending loans to customers. Fees for letters of credit are initially recorded by the Company as deferred revenue and are included in earnings at the termination of the respective agreements. Should the Company be obligated to perform under the standby letters of credit, the Company may seek recourse from the customer for reimbursement of amounts paid. Lines of Credit Lines of credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Lines of credit generally have fixed expiration dates. Since a portion of the line may expire without being drawn upon, the total unused lines do not necessarily represent future cash requirements. Each customer’s creditworthiness is evaluated on a case by case basis. The amount of collateral obtained, if deemed necessary, is based on management’s credit evaluation of the counterparty. Collateral held varies but may include accounts receivable, inventory, property, plant and equipment, commercial real estate and residential real estate. Management uses the same credit policies in granting lines of credit as it does for on-balance sheet instruments. Commitments related to Investment Fund The Company entered into a subscription agreement with a third party to invest up to $ 2.5 million in an investment fund designed to help accelerate technology adoption at community banks. Lease Commitments The Company entered into a lease agreement with a third party for office space located in Dallas, Texas. The triple-net lease is expected to commence in the second quarter of 2022. The initial lease term is 20 years with two , five year renewal options.

Equity [Abstract]
Stocks Offerings and Repurchases	Note 22: Stock Offerings and Repurchases On October 18, 2021, the Company announced that its Board of Directors adopted a new stock repurchase program. Under the repurchase program, the Company may repurchase up to $ 30 million of the Company’s common stock. As of December 31, 2021, the Company had repurchased $ 8 million, representing 566,164 common shares. In October 2020, the Company announced a $ 20 million program to repurchase the Company’s common stock. The repurchased shares are held in the treasury stock account until sold or retired and will be accounted for on a first-in first-out method. On June 30, 2021, the Company completed its share repurchase program under which the Company purchased $ 20 million of its common stock. The Company completed its IPO on August 19, 2019 in which it issued and sold 6,594,362 common shares including 844,362 shares pursuant to the underwriters’ partial exercise of their over-allotment option. The common shares were sold at an initial public offering price of $ 14.50 per share. After deducting the underwriting discounts and offering expenses, the Company received total net proceeds of $ 87 million. The Company redeemed all, 1,200,000 , of its 7.00 % Series A Non-Cumulative Perpetual Preferred Stock (the “Series A Preferred Shares”) on January 30, 2019 (the “Redemption Date”). On the Redemption Date, we redeemed each outstanding Series A Preferred Share at a redemption price of $ 25.00 per share. From and after the Redemption Date, all of the Series A Preferred Shares ceased to be outstanding, all dividends with respect to the Series A Preferred Shares ceased to accrue and all rights with respect to the Series A Preferred Shares ceased and terminated, except the rights of holders to receive the redemption price per share of the Series A Preferred Shares. The impact of the redemption was a reduction of approximately $ 30 million in cash and cash equivalents and stockholders’ equity. The redemption did not impact the income statement. The Company has various stock-based awards that are converted into common stock upon vest or exercise. Additional information related to stock-based awards can be found in Note 16: Stock-Based Compensation and information related to warrants can be found in Note 17: Stock Warrants .

Nature of Operations and Summary of Significant Accounting Policies [Abstract]
Organization and Nature of Operations	Organization and Nature of Operations CrossFirst Bankshares, Inc. (consolidated) (the “Company”), a Kansas corporation, is a bank holding company whose principal activities are the ownership and management of its wholly owned subsidiary, CrossFirst Bank (a subsidiary of CrossFirst Bankshares, Inc.) (the “Bank”). The Bank has three wholly owned subsidiaries: (i) CrossFirst Investments, Inc. holds investments in marketable securities; (ii) CFBSA I, LLC that can hold foreclosed assets; and (iii) CFBSA II, LLC that can hold foreclosed assets. The Bank is primarily engaged in providing a full range of banking and financial services to individual and corporate customers through its branches in: (i) Leawood, Kansas; (ii) Wichita, Kansas; (iii) Kansas City, Missouri; (iv) Oklahoma City, Oklahoma; (v) Tulsa, Oklahoma; (vi) Dallas, Texas; (vii) Frisco, Texas; and (viii) Phoenix, Arizona. The Bank is subject to competition from other financial institutions and the regulation of certain federal and state agencies and undergoes periodic examinations by those regulatory authorities.
Basis of Presentation	Basis of Presentation The Company’s accounting and reporting policies conform to accounting principles generally accepted in the United States (“GAAP”). The consolidated financial statements include the accounts of the Company; the Bank and its wholl y-owned subsidiaries, CrossFirst Investments, Inc., CFBSA I, LLC and CFBSA II, LLC. All significant intercompany accounts and transactions were eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses, valuation of deferred tax assets, other-than-temporary impairments (“OTTI”), stock based compensation, derivatives, and fair values of financial instruments.
Change in Accounting Principle, Recent Accounting Pronouncements and Accounting Guidance Adopted	Changes in Accounting Principle On December 31, 2021, the Company adopted the Financial Accounting Standards Board (“FASB”) Accounting Standard Update (“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 in the current period of adoption, which was applied on a prospective basis. A description of the nature and reason for the change in accounting principle is provided below in the recent accounting pronouncements section. Recent Accounting Pronouncements The following ASUs represent changes to current accounting guidance that will be adopted in future years: Accounting Guidance Adopted During Fiscal Years 2021, 2020, and 2019 Standard Anticipated Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2020-05 Revenue from Contracts with Customers (Topic 606) and Leases (Topic 842): Effective Dates for Certain Entities Effective immediately, but included here for information purposes as it relates to the ASU listed in the “description” section. Amended the mandatory effective date for ASU 2016-02 (Leases). The amended dates were incorporated into the “anticipated date of adoption” section for the appropriate ASU below. No expected impact to the financial statements, but delays certain ASUs for private companies, and EGCs that elected to use the private company effective dates for new or revised accounting standards. If the Company loses its EGC status during the fiscal year, the Company would be required to review all ASUs as a Public Business Entity (“PBE”) and adopt any ASU effective for PBEs as of the first day of that year. ASU 2019-10 Financial Instruments-Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates Effective immediately, but included here for informational purposes as it relates to the ASU listed in the “description” section. Amended the mandatory effective dates for all entities related to: (i) credit losses - ASU 2016-13; (ii) goodwill - ASU 2017-04; (iii) leases - ASU 2016-02; and (iv) hedging - ASU 2017-12 The amended dates were incorporated into the “anticipated date of adoption” section for the appropriate ASU below. No expected impact to the financial statements, but delays certain ASUs for private companies, smaller reporting companies and EGCs that elected to use the private company effective dates for new or revised accounting standards. If a company loses its EGC status during the fiscal year, the company would be required to review all ASUs as a PBE and adopt any ASU effective for PBEs as of the first day of that year. Standard Anticipated Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2019-04 Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments Updates related to ASU 2016-13 are effective at the same time as ASU 2016-13. Provided an election to measure separately or not measure an allowance for credit losses ("ACL") for accrued interest receivable. Provided an election to write-off uncollectible interest as a reversal of interest income or a charge against the ACL or a combination of both. Clarified that recoveries, including recoveries of amounts expected to be written off and those previously written off, should be incorporated within the estimation of the ACL. Clarified that contractual extensions or renewal options that are not unconditionally cancellable by the lender are considered when determining the contractual term over which expected credit losses are measured. The Company elected to exclude accrued interest receivable from the ACL. The Company has existing practices in place for the timely write-off of uncollectable accrued interest receivable. The Company plans to adjust the historical loss information to reflect the amount of accrued interest that would have been charged off if the entity had not applied a nonaccrual accounting policy. The Company elected to reverse interest income when accrued interest receivable is written off, which is similar to past accounting practice. Additional information regarding the Company's transition to ASU 2016-13 is provided below. Standard Anticipated Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2016-13 Financial Instruments-Credit Losses If the Company maintains its EGC status, the Company is not required to implement this standard until January 2023. The Company expects to adopt this standard on January 1, 2022. Requires an entity to utilize a new impairment model known as the current expected credit loss ("CECL") model to estimate its lifetime expected credit loss and record an allowance that, when deducted from amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. The Company established a committee to formulate and oversee the implementation process including selection, implementation and testing of third-party software. The Company began parallel processing with the existing allowance for loan losses model during the first quarter of 2019 recalibrating inputs as necessary. The Company formulated changes to policies, procedures, disclosures and internal controls that were necessary in order to transition to the new standard. A third-party completed validation of the completeness, accuracy and reasonableness of the model in the fourth quarter of 2021. The Company plans to use a loss-rate ("cohort") method to estimate the expected allowance for credit losses ("ACL") for all loan pools. The Cohort method identifies and captures the balance of a pool of loans with similar risk characteristics, as of a particular point in time to form a cohort, then tracks the respective losses generated by that cohort of loans over their remaining lives, or until the loans are “exhausted” (i.e.; have reached an acceptable point in time at which a significant majority of all losses are expected to have been recognized). The cohort method closely aligns with the Company's incurred loss model. This allows the Company to take advantages of the efficiencies of processes and procedures already in practice. The Company's loan categories will be similar to those used under the current, incurred loss model, but will break out the Commercial loan category into Commercial and Commercial lines of credit. Upon adoption in 2022, a cumulative-effect adjustment, net of tax for the change in the ACL will be recognized in retained earnings. These results include the adoption of a forecast based on several economic assumptions, including unemployment rates and management judgments. Adoption will not materially impact reporting for debt securities as the Company does not currently own held-to-maturity debt securities within the scope of ASU 2016-13. Standard Anticipated Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2016-02 Leases (Topic 842) The Company expects to early adopt this standard on January 1, 2022. Requires lessees and lessors to recognize lease assets and lease liabilities on the balance sheet and disclose key information about leasing arrangements. The update requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach with the option to elect certain practical expedients. The update will also increase disclosures around leases, including qualitative and specific quantitative measures. The Company expects to apply the update as of the beginning of the period of adoption and the Company does not plan to restate comparative periods. The Company expects to elect certain optional practical expedients. The Company performed a search for all property leases and potential embedded leases inside other third-party agreements, The Company's review for embedded leases focused on third-party software as a service ("SAAS") agreements and determined if the Company had the right to control a specified asset over a period of time in exchange for consideration. The Company’s current operating leases relate primarily to five branch locations. The Company expects to record approximately $ 27 million for the lease liability and $ 25 million for the right of use asset on its balance sheet, with an immaterial impact to its income statement compared to the current lease accounting model. Standard Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2021-06 Presentation of Financial Statement (Topic 205), Financial Services - Depository and Lending (Topic 942), and Financial Services - Investment Companies (Topic 946) - Amendments to SEC Paragraphs Pursuant to SEC Final Rule Releases No. 33-10786, Amendments to Financial Disclosures about Acquired and Disposed Businesses, and No. 33- 10835, Update of Statistical Disclosures for Bank and Savings and Loan Registrants Effective on issuance Applicable to fiscal years ending on or after December 15, 2021 ASU adds or amends SEC paragraphs in the Accounting Standards Codification that describe SEC guidance or SEC staff views that the Financial Accounting Standards Board includes as a convenience to Codification users. SEC Release No. 33-10835; 34-89835; and File No. S7- 02-17, updated and codified the Statistical Disclosures for Bank and Savings and Loan Registrants. The amendments update and expand the disclosures that registrants are required to provide, codify certain Guide 3 disclosure items and eliminate other Guide 3 disclosure items that overlap with Commission rules or U.S. Generally Accepted Accounting Principles. In addition, the disclosure requirements were added to a new subpart of Regulation S-K and rescinds Guide 3. The ASU did not have a material impact on the Company's consolidated financial statements, but impacted disclosure requirements in the Company's Form 10-K, including: - Distribution of assets, liabilities and stockholders' equity; - Weighted average yield of each maturity category of debt securities not carried at fair value through earnings; - Maturity analysis of the loan portfolio; - Certain credit ratios, including requiring the disclosure of the allowance for loan losses to total loans, nonaccrual loans to total loans, allowance for loan losses to nonaccrual loans, and net charge-offs to average loans by loan category; - Allowance for loan losses by category; and - average deposit rates paid and amount that are uninsured. ASU 2021-04 Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options December 31, 2021 (early adopted and is being applied as of January 1, 2021) Clarifies and reduces diversity in an issuer's accounting for modifications or exchanges of freestanding equity- classified written call options that remain equity- classified. An issuer should measure the effect of a modification as the difference between the fair value of the modified warrant and the fair value of that warrant immediately before modification. The recognition of the modification depends on the nature of the transaction in which a warrant is modified: (i) Equity issuance - recorded as deferred costs of an equity offering; (ii) Debt origination - recorded as a debt discount if held by the lender or debt issuance costs if held by a third party; (iii) Debt modification - recorded as a fee paid to or received from the creditor, if held by a creditor, and as a third party cost if held by a third party; and (iv) All other modifications - recorded as a dividend that reduces retained earnings. The Company had 113,500 warrants outstanding as of December 31, 2021. The amendments in the ASU did not have a material impact on the Company's year-end or interim consolidated financial statements. Standard Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2018-16 Derivative and Hedging (Topic 815) Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes December 31, 2021 (applied as of January 1, 2021) Permit use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes in addition to the UST, the LIBOR swap rate, the OIS rate based on the Fed Funds Effective Rate, and the SIFMA Municipal Swap Rate. The change will apply prospectively for qualifying new or redesignated hedging relationships entered into on or after the date of adoption. The ASU did not have a material impact on the Company's year-end or interim consolidated financial statements. ASU 2018-15 Intangibles-Goodwill and Other- Internal-Use Software December 31, 2021 (applied as of January 1, 2021) 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. The Company elected to apply the change in accounting principle prospectively. A review of third-party, hosting arrangements, including software-as-a-service ("SaaS") arrangements, that were in the implementation stage was performed in 2021 to ensure applicable implementation costs were capitalized and will be amortized over the service period. SaaS arrangements are service contracts providing the Company with the right to access the cloud provider’s application software over the contract period. As such the Company does not receive a software intangible asset at the contract commencement date. A right to receive future access to the supplier’s software does not, at the contract commencement date, give the customer the power to obtain the future economic benefits flowing from the software itself and to restrict others’ access to those benefits The ASU did not have a material impact on the Company's year-end or interim consolidated financial statements. The Company's previous capitalization policies were similar to the ASU requirements. ASU 2017-12 Derivatives and Hedging (Topic 815) Targeted Improvements to Accounting for Hedging Activities December 31, 2021 (applied as of January 1, 2021) Simplifies and expands the eligible hedging strategies for financial and nonfinancial risks. Enhances the transparency of how hedging results are presented and disclosed. Provides partial relief on the timing of certain aspects of hedge documentation and eliminates the requirement to recognize hedge ineffectiveness separately in earnings. During the year ended December 31, 2021, the Company began entering into cash flow hedges. As of December 31, 2021, the total number of cash flow hedges was 5 with an aggregate notional amount of $ 100 million. The amendments in the ASU did not have a material impact on the Company's year-end or interim consolidated financial statements. Standard Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2020-04: Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting June 30, 2020 The ASU provides optional expedients and exceptions to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The ASU only applies to transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The amendments include: (1) Optional expedients to contract modifications that allow the Company to adjust the effective interest rate of receivables and debt, account for lease modifications as a continuation of the existing lease, and remove the requirement to reassess its original conclusions for contract modifications about whether that contract contains an embedded derivative that is clearly and closely related to the economic characteristics and risks of the host contract under Subtopic 815-15, Derivatives and Hedging— Embedded Derivatives; (2) Exceptions to the guidance in Topic 815 related to changes in the critical terms of a hedging relationship due to reference rate reform; and (3) Optional expedients for cash flow and fair value hedges. The Company had more than $ 1 billion in loans tied to LIBOR as of December 31, 2020. The adoption did not have a material accounting impact on the Company’s consolidated financial position or results of operations. Additionally, LIBOR fallback language has been included in key loan provisions of new and renewed loans in preparation for transition from LIBOR to the new benchmark rate when such transition occurs. This standard is expected to ease the administrative burden in accounting for the future effects of reference rate reform. The ASU allows the Company to recognize the modification related to LIBOR as a continuation of the old contract, rather than a cancellation of the old contract resulting in a write off of unamortized fees and creation of a new contract. ASU 2019-12: Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes January 1, 2020 (Early Adoption) The ASU simplifies the accounting for income taxes. Among other changes, the ASU: (1) Removes the exception to the incremental approach for intraperiod tax allocation when there is a loss from continuing operations and income or a gain from other items; (2) Removes the exception to the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year; (3) Requires an entity to recognize a franchise tax that is partially based on income as an income-based tax and account for any incremental amount incurred as a nonincome based tax; and (4) Requires an entity to reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. The amendments in the ASU did not have a material impact on the Company’s tax methodology, processes, or the Company’s financial statements. Standard Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2018-13: Fair Value Measurement (Topic 820): Disclosure Framework January 1, 2020 Improves the effectiveness of disclosures in the notes to financial statements by facilitating clear communication of the information. The amendments modify certain disclosure requirements of fair value measurements in Topic 820, Fair Value Measurement. Entities are no longer required to disclose transfers between Level 1 and Level 2 of the fair value hierarchy or qualitatively disclose the valuation process for Level 3 fair value measurements. The updated guidance requires disclosure of the changes in unrealized gains and losses for the period included in Other Comprehensive Income for recurring Level 3 fair value measurements. Entities are required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. The additional provisions of the guidance should be adopted prospectively. The eliminated requirements should be adopted retrospectively. The adoption did not have a material impact to the Company’s financial statements. No transfers between Level 1 and Level 2 occurred in 2019 or 2020 and the Company did not have any recurring Level 3 fair value measurements that created an unrealized gain or loss in Other Comprehensive Income. In addition, the Company previously disclosed the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. ASU 2017-04: Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment January 1, 2020 (Early Adoption) Eliminates Step 2 from the goodwill impairment test which required entities to compute the implied fair value of goodwill. An entity should perform an annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. On the date of adoption, there was no impact to the Company’s financial statements. The Company’s process for evaluating goodwill impairment was modified to align with the elimination of Step 2. In the second quarter of 2020, the Company performed a Step 0 analysis then a Step 1 analysis and determined that goodwill was fully impaired. ASU 2016-01: Financial Instruments- Overall (Subtopic 825-10) January 2019 Required equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. Emphasized the existing requirement to use exit prices to measure fair value for disclosure purposes and clarifies that entities should not make use of practicability exceptions in determining the fair value of loans. The Company transferred $ 69 thousand from accumulated other comprehensive loss to retained earnings in January 2019. There was no impact to the income statement on the adoption date. Standard Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2018-07: Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting January 2019 Early adoption Expanded the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees, excluding share-based payments used to effectively provide: (i) financing to the issuer or (ii) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The amendments include: (i) grants are measured at grant-date fair value of the equity instruments; (ii) equity-classified nonemployee share-based payment awards are measured at the grant date;(iii) performance based awards are measured based on the probability of satisfying the performance conditions and (iv) in general, non- employee share-based payment awards will continue to be subject to the requirements of ASC 718 unless modified after the good has been delivered, the service has been rendered, any other conditions necessary to earn the right to benefit from the instrument have been satisfied, and the nonemployee is no longer providing goods or services. The Company had 216,960 stock-based awards to non-employees as of the implementation date, including 116,960 performance- based restricted stock units. The adoption of the ASU allowed the Company to: (i) set the fair market value of the non-employee awards as of the adoption date; and (ii) start to expense the performance-based restricted stock units based on the probability of satisfying the performance conditions. Adoption of ASU 2018-07 required the Company to make a one time transfer of $ 2 million from retained earnings to additional paid in capital. In addition, the Company recorded a $ 306 thousand deferred tax asset that was offset with retained earnings to account for the tax impact. The Company will record forfeitures as they occur and base fair market values on the expected term, like the Company’s accounting for employee-based awards. ASU 2014-09: Revenue from Contracts with Customers January 2019 Amended guidance related to revenue from contracts with customers. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Replaced nearly all existing revenue recognition guidance, including industry specific guidance, established a new control based revenue recognition model, changed the basis for deciding when revenue is recognized over time or at a point in time, provided new and more detailed guidance on specific topics and expands and improves disclosures about revenue. The accounting update did not materially impact the financial statements or recognition of revenues. The update did not apply to revenue associated with financial instruments, including loans and securities that are accounted for under other GAAP, which comprises a significant portion of the Company’s revenue stream. In addition, the Company’s noninterest income is generated by customer transactions or through the passage of time and as a result the pattern or timing of income recognition was not impacted.
Changes Affecting Comparability	Changes Affecting Comparability For the year ended December 31, 2021, the Company broke out “gains (losses), net on equity securities” that was previously reported in other non-interest income. As a result, changes within the Consolidated Statements of Income in the prior periods were made to conform to the current period presentation. The change provides additional detail about the Company’s operations. The changes had no impact on net income. For the year ended December 31, 2021, the Company consolidated the “Goodwill and other intangible assets, net” into “other assets” within the Consolidated Balance Sheets. The consolidation was due to the immateriality of the remaining intangible assets. The change had no impact on net income.
Operating Segments	Operating Segments An operating segment is a component of an entity that has separate financial information related to its business activities and is reviewed by the chief operating decision maker on a regular basis to allocate resources and assess performance. The Company identifies the following markets as operating segments: (i) Kansas City, Missouri and Leawood, Kansas; (ii) Wichita, Kansas; (iii) Oklahoma City, Oklahoma; (iv) Tulsa, Oklahoma; (v) Energy bank; (vi) Dallas and Frisco, Texas; and (vii) Phoenix, Arizona. These markets provide similar products and services using a similar process to a similar customer base. Our products and services include, but are not limited to, loans; checking and savings accounts; time deposits and credit cards. Loan products include commercial, real estate, consumer, and Small Business Administration (“SBA”) lending. The regulatory environment is the same for the markets as well. The chief operating decision maker monitors the revenue and costs of the markets; however, operations are managed, including allocation of resources, and financial performance is evaluated on a Company-wide basis. As a result, the markets are aggregated into one reportable segment.
Cash Equivalents	Cash Equivalents The Company considers all liquid investments with original maturities of three months or less to be cash equivalents. At December 31, 2021, cash equivalents consisted primarily of both interest-bearing and noninterest bearing accounts with other banks. Approximately $ 417 million of the Company’s cash and cash equivalents were held at the Federal Reserve Bank of Kansas City at December 31, 2021. The Company is required to maintain reserve funds in cash and/or on deposit with the Federal Reserve Bank. The reserve required at December 31, 2021 was $ 0 . In addition, the Company is required from time to time to place cash collateral with third parties as part of its back-to-back swap agreements and cash flow hedges. At December 31, 2021, $ 17 million was required as cash collateral. At December 31, 2021, the Company’s cash accounts, excluding funds at the Federal Reserve Bank and funds required as cash collateral, exceeded federally insured limits by $ 35 million.
Securities	Securities Debt securities for which the Company has no immediate plan to sell but which may be sold in the future, are classified as available-for-sale (“AFS”) and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Gains and losses on the sale of debt securities are recorded on the trade date and are determined using the specific identification method. Equity securities are recorded at fair value with unrealized gains and losses included in earnings. Gains and losses on the sale of equity securities are recorded on the trade date and are determined using the specific identification method. The Company elected a measurement alternative for two equity investment s that did not have a readily determinable fair value and did not qualify for the practical expedient to estimate fair value using the net asset value per share. A cost basis was calculated for the equity investments. The recorded balance will adjust for any impairment or any observable price changes for an identical or similar investment of the same issuer. The Company routinely conducts periodic reviews to identify and evaluate each debt security to determine whether an OTTI has occurred. For available-for-sale securities that management has no intent to sell and believes that it more likely than not will not be required to sell prior to recovery, only the credit loss component of the impairment is recognized in earnings, while the noncredit loss is recognized in accumulated other comprehensive income. The credit loss component recognized in earnings is identified as the amount of principal cash flows not expected to be received over the remaining term of the security as projected based on cash flow projections.
Loans	Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their outstanding principal balances adjusted for unearned income, charge-offs, the allowance for loan losses, any unamortized deferred fees or costs on originated loans and unamortized premiums or discounts on purchased loans. For loans amortized at cost, interest income is accrued based on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, as well as premiums and discounts, are deferred and amortized as a level yield adjustment over the respective term of the loan.
Nonperforming Loans	Nonperforming Loans Nonperforming loans are loans for which we do not accrue interest income. The accrual of interest on mortgage and commercial loans is discontinued at the time the loan is 90 days past due unless the credit is well secured and in process of collection. A credit is considered well secured if it is secured by collateral in the form of liens or pledges of real or personal property, including securities, that have a realizable value sufficient to discharge the debt (including accrued interest) in full or is secured by the guaranty of a financially responsible party. A debt is in the process of collection if collection of the debt is proceeding in due course either through legal action, including enforcement procedures, or in appropriate circumstances, through collection efforts not involving legal action which are reasonably expected to result in repayment of the debt or in its restoration to a current status. Past due status is based on contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged off at an earlier date, if collection of principal or interest is considered doubtful. All interest accrued but not collected for loans that are placed on nonaccrual or charged off are reversed against interest income. The interest on these loans is accounted for on the cash basis or cost recovery method, until qualifying for return to accrual. When payments are received on nonaccrual loans, payments are applied to principal unless there is a clear indication that the quality of the loan has improved to the point that it can be placed back on accrual status. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.
Allowance for Loan Losses	Allowance for Loan Losses The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to income. Loan losses are charged against the allowance when management believes the loan balance is not collectible. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of its ability to collect the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The allowance consists of allocated and general components. The allocated component relates to loans that are individually classified as impaired. For those loans that are classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers the remaining pool of loans and is based on historical charge-off experience and expected loss given default derived from the Company’s internal risk rating process. Other adjustments may be made to the allowance for pools of loans after an assessment of internal or external influences on credit quality that are not fully reflected in the historical loss or risk rating data. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on an individual loan basis by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price or the fair value of the collateral, if the loan is collateral dependent. Groups of loans with similar risk characteristics are collectively evaluated for impairment based on the group’s historical loss experience adjusted for changes in trends, conditions and other relevant factors that affect repayment of the loans.
Premises and Equipment	Premises and Equipment Depreciable assets are stated at cost less accumulated depreciation. Depreciation is charged to expense using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are capitalized and depreciated using the straight-line method over the terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter. Expected terms include lease option periods to the extent that the exercise of such options is reasonably assured. The estimated useful lives for each major depreciable classification of premises and equipment are as follows: Buildings and improvements 35 - 40 years Leasehold improvements 5 - 15 years Furniture and fixtures 5 - 7 years Equipment 3 - 5 years
Long-Lived Asset Impairment	Long-Lived Asset Impairment The Company evaluates the recoverability of the carrying value of long-lived assets whenever events or circumstances indicate the carrying amount may not be recoverable. If a long-lived asset is tested for recoverability and the undiscounted estimated future cash flows expected to result from the use and eventual disposition of the asset is less than the carrying amount of the asset, the asset cost is adjusted to fair value and an impairment loss is recognized as the amount by which the carrying amount of a long-lived asset exceeds its fair value.
Restricted Equity Securities	Restricted Equity Securities Restricted equity securities include investments in FHLB Topeka and Bankers’ Bank of Kansas. FHLB Topeka is a Federal Home Loan Bank and its stock is a required investment for institutions that are members of the Federal Home Loan System. The required investment in the common stock is based on a predetermined formula. The Bankers’ Bank of Kansas is a correspondent bank located in Wichita, Kansas and the investment is carried at cost and evaluated for impairment.
Bank-Owned Life Insurance	Bank-Owned Life Insurance The Company has purchased life insurance policies on certain key employees that are accounted for under the fair value method. Bank-owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value. Changes in cash surrender value are recorded in earnings in the period in which the changes occur.
Foreclosed Assets Held-for-Sale	Foreclosed Assets Held-for-Sale Assets acquired through, or in lieu of, loan foreclosure are held-for-sale and are initially recorded at fair value less cost to sell at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less cost to sell. Revenue and expenses from operations and changes in the valuation allowance are included in net income or expenses from foreclosed assets.
Goodwill	Goodwill Goodwill was evaluated annually for impairment or more frequently if impairment indicators were present. A qualitative assessment was performed to determine whether the existence of events or circumstances led to a determination that it was more likely than not the fair value was less than the carrying amount, including goodwill. If, based on the evaluation, it was determined to be more likely than not that the fair value was less than the carrying value, then goodwill was tested further for impairment. If the implied fair value of goodwill was lower than its carrying amount, a goodwill impairment was indicated and goodwill was written down to its implied fair value.
Core Deposit Intangible	Core Deposit Intangible The core deposit intangible represents the identified intangible asset relating to the deposit relationships acquired in past business combinations. The value of the core deposit intangible is based primarily upon the expected future benefits of earnings capacity attributable to those deposits.
Related Party Transactions	Related Party Transactions The Company extends credit and receives deposits from related parties. In management’s opinion, the loans and deposits were made in the ordinary course of business and made on similar terms as those prevailing at the time with other persons. Related party loans totaled $ 8 million and $ 16 million at December 31, 2021 and 2020, respectively. Related party deposits totaled $ 74 million and $ 55 million at December 31, 2021 and 2020, respectively.
Stock-Based Compensation	Stock-Based Compensation The Company accounts for all stock-based compensation transactions in accordance with Accounting Standard Codification (“ASC”) 718, Compensation - Stock Compensation, which requires that stock compensation transactions be recognized as compensation expense in the consolidated statement of income based on their fair values on the measurement date. The Company recognizes forfeitures as they occur. New shares are issued upon exercise of an award. The Company records permanent tax differences through the income tax provision upon vesting or exercise of a stock-based award. The various stock-based compensation plans are described more fully in Note 16: Stock-Based Compensation .
Transfers of Financial Assets	Transfers of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when: (i) the assets have been isolated from the Company and put presumptively beyond the reach of the transferor and its creditors, even in bankruptcy or other receivership; (ii) 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 (iii) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets.
Income Taxes	Income Taxes The Company accounts for income taxes in accordance with income tax accounting guidance (ASC 740, Income Taxes). The income tax accounting guidance results in two components of income tax expense: (i) current; and (ii) deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over revenues. The Company determines deferred income taxes using the liability or balance sheet method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities and enacted changes in tax rates and laws are recognized in the period in which they occur. Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term, more likely than not, means a likelihood of more than 50 percent; the terms examined and upon examination also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more likely than not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more likely than not recognition threshold considers the facts, circumstances and information available at the reporting date and is subject to management’s judgment. Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized. The Company recognizes interest and penalties on income taxes as a component of income tax expense. The Company files consolidated income tax returns with its subsidiaries. Due to the carry forward of federal net operating losses, all prior years remain subject to examination by federal tax authorities.
Earnings Per Share	Earnings Per Share Basic earnings per share represent net income available to common stockholders divided by the weighted average number of common shares outstanding during each period. Diluted earnings per share reflect additional potential shares that would have been outstanding if dilutive potential common stock had been issued, as well as any adjustment to income that would result from the assumed issuance. Potential common stock that may be issued by the Company is determined using the treasury stock method.
Fair Values of Financial Instruments	Fair Values of Financial Instruments The Company follows the applicable accounting guidance for fair value measurements and disclosures for all applicable financial and nonfinancial assets and liabilities. ASC 820, Fair Value Measurements and Disclosures (“ASC 820”), defines fair value, establishes a framework for measuring fair value under GAAP and enhances disclosures about fair value measurements. The Company values financial instruments based upon quoted market prices, where available. If market prices are not available, fair value is based on pricing models that use available information including quoted prices for similar assets or liabilities in active markets, market indicators, and industry and economic events. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows.
Comprehensive Income	Comprehensive Income Comprehensive income consists of net income and other comprehensive income, net of applicable income taxes. Other comprehensive income includes unrealized appreciation (depreciation) on available-for-sale securities and cash flow hedges.
Derivative Financial Instruments	Derivative Financial Instruments ASC 815, Derivatives and Hedging, provides the disclosure requirements for derivatives and hedging activities with the intent to provide users of financial statements with an enhanced understanding of: (i) how and why an entity uses derivative instruments; (ii) how the entity accounts for derivative instruments and related hedged items; and (iii) how derivative instruments and related hedged items affect an entity’s financial position, financial performance, and cash flows. Further, qualitative disclosures are required that explain the Company’s objectives and strategies for using derivatives, as well as quantitative disclosures about the fair value of and gains and losses on derivative instruments, and disclosures about credit risk related contingent features in derivative instruments. As required by ASC 815, the Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the 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. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. In accordance with the Financial Accounting Standards Board's (“FASB”) fair value measurement guidance in ASU 2011-04, the Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counter-party portfolio.
Emerging Growth Company (EGC)	Emerging Growth Company (“EGC”) The Company is currently an EGC. An EGC may take advantage of reduced reporting requirements and is relieved of certain other significant requirements that are otherwise generally applicable to public companies. Among the reductions and reliefs, the Company elected to extend the transition period for complying with new or revised accounting standards affecting public companies. This means that the financial statements the Company files or furnishes, will not be subject to all new or revised accounting standards generally applicable to public companies for the transition period for so long as the Company remains an EGC or until the Company affirmatively and irrevocably opts out of the extended transition period under the JOBS Act.
Coronavirus Aid, Relief, and Economic Security Act (CARES Act)	Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) The CARES Act and extended by the Consolidated Appropriations Act of 2021 allowed financial institutions to elect not to consider whether loan modifications relating to the COVID-19 pandemic that they make between March 1, 2020 and December 31, 2021 were troubled debt restructurings (“TDRs”), which required additional disclosures. The relief was applied to modifications of loans to borrowers that were not more than 30 days past due as of December 31, 2019 and were impacted by COVID-19. The Company elected to apply the guidance during the first quarter of 2020. The review of loans that met the criteria was overseen by the Office of the Chief Credit Officer and his team.

Schedule of Recent Accounting Pronouncements, Adopted Accounting Guidance and Changes in Accounting Principles	Standard Anticipated Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2020-05 Revenue from Contracts with Customers (Topic 606) and Leases (Topic 842): Effective Dates for Certain Entities Effective immediately, but included here for information purposes as it relates to the ASU listed in the “description” section. Amended the mandatory effective date for ASU 2016-02 (Leases). The amended dates were incorporated into the “anticipated date of adoption” section for the appropriate ASU below. No expected impact to the financial statements, but delays certain ASUs for private companies, and EGCs that elected to use the private company effective dates for new or revised accounting standards. If the Company loses its EGC status during the fiscal year, the Company would be required to review all ASUs as a Public Business Entity (“PBE”) and adopt any ASU effective for PBEs as of the first day of that year. ASU 2019-10 Financial Instruments-Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates Effective immediately, but included here for informational purposes as it relates to the ASU listed in the “description” section. Amended the mandatory effective dates for all entities related to: (i) credit losses - ASU 2016-13; (ii) goodwill - ASU 2017-04; (iii) leases - ASU 2016-02; and (iv) hedging - ASU 2017-12 The amended dates were incorporated into the “anticipated date of adoption” section for the appropriate ASU below. No expected impact to the financial statements, but delays certain ASUs for private companies, smaller reporting companies and EGCs that elected to use the private company effective dates for new or revised accounting standards. If a company loses its EGC status during the fiscal year, the company would be required to review all ASUs as a PBE and adopt any ASU effective for PBEs as of the first day of that year. Standard Anticipated Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2019-04 Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments Updates related to ASU 2016-13 are effective at the same time as ASU 2016-13. Provided an election to measure separately or not measure an allowance for credit losses ("ACL") for accrued interest receivable. Provided an election to write-off uncollectible interest as a reversal of interest income or a charge against the ACL or a combination of both. Clarified that recoveries, including recoveries of amounts expected to be written off and those previously written off, should be incorporated within the estimation of the ACL. Clarified that contractual extensions or renewal options that are not unconditionally cancellable by the lender are considered when determining the contractual term over which expected credit losses are measured. The Company elected to exclude accrued interest receivable from the ACL. The Company has existing practices in place for the timely write-off of uncollectable accrued interest receivable. The Company plans to adjust the historical loss information to reflect the amount of accrued interest that would have been charged off if the entity had not applied a nonaccrual accounting policy. The Company elected to reverse interest income when accrued interest receivable is written off, which is similar to past accounting practice. Additional information regarding the Company's transition to ASU 2016-13 is provided below. Standard Anticipated Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2016-13 Financial Instruments-Credit Losses If the Company maintains its EGC status, the Company is not required to implement this standard until January 2023. The Company expects to adopt this standard on January 1, 2022. Requires an entity to utilize a new impairment model known as the current expected credit loss ("CECL") model to estimate its lifetime expected credit loss and record an allowance that, when deducted from amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. The Company established a committee to formulate and oversee the implementation process including selection, implementation and testing of third-party software. The Company began parallel processing with the existing allowance for loan losses model during the first quarter of 2019 recalibrating inputs as necessary. The Company formulated changes to policies, procedures, disclosures and internal controls that were necessary in order to transition to the new standard. A third-party completed validation of the completeness, accuracy and reasonableness of the model in the fourth quarter of 2021. The Company plans to use a loss-rate ("cohort") method to estimate the expected allowance for credit losses ("ACL") for all loan pools. The Cohort method identifies and captures the balance of a pool of loans with similar risk characteristics, as of a particular point in time to form a cohort, then tracks the respective losses generated by that cohort of loans over their remaining lives, or until the loans are “exhausted” (i.e.; have reached an acceptable point in time at which a significant majority of all losses are expected to have been recognized). The cohort method closely aligns with the Company's incurred loss model. This allows the Company to take advantages of the efficiencies of processes and procedures already in practice. The Company's loan categories will be similar to those used under the current, incurred loss model, but will break out the Commercial loan category into Commercial and Commercial lines of credit. Upon adoption in 2022, a cumulative-effect adjustment, net of tax for the change in the ACL will be recognized in retained earnings. These results include the adoption of a forecast based on several economic assumptions, including unemployment rates and management judgments. Adoption will not materially impact reporting for debt securities as the Company does not currently own held-to-maturity debt securities within the scope of ASU 2016-13. Standard Anticipated Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2016-02 Leases (Topic 842) The Company expects to early adopt this standard on January 1, 2022. Requires lessees and lessors to recognize lease assets and lease liabilities on the balance sheet and disclose key information about leasing arrangements. The update requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach with the option to elect certain practical expedients. The update will also increase disclosures around leases, including qualitative and specific quantitative measures. The Company expects to apply the update as of the beginning of the period of adoption and the Company does not plan to restate comparative periods. The Company expects to elect certain optional practical expedients. The Company performed a search for all property leases and potential embedded leases inside other third-party agreements, The Company's review for embedded leases focused on third-party software as a service ("SAAS") agreements and determined if the Company had the right to control a specified asset over a period of time in exchange for consideration. The Company’s current operating leases relate primarily to five branch locations. The Company expects to record approximately $ 27 million for the lease liability and $ 25 million for the right of use asset on its balance sheet, with an immaterial impact to its income statement compared to the current lease accounting model. Standard Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2021-06 Presentation of Financial Statement (Topic 205), Financial Services - Depository and Lending (Topic 942), and Financial Services - Investment Companies (Topic 946) - Amendments to SEC Paragraphs Pursuant to SEC Final Rule Releases No. 33-10786, Amendments to Financial Disclosures about Acquired and Disposed Businesses, and No. 33- 10835, Update of Statistical Disclosures for Bank and Savings and Loan Registrants Effective on issuance Applicable to fiscal years ending on or after December 15, 2021 ASU adds or amends SEC paragraphs in the Accounting Standards Codification that describe SEC guidance or SEC staff views that the Financial Accounting Standards Board includes as a convenience to Codification users. SEC Release No. 33-10835; 34-89835; and File No. S7- 02-17, updated and codified the Statistical Disclosures for Bank and Savings and Loan Registrants. The amendments update and expand the disclosures that registrants are required to provide, codify certain Guide 3 disclosure items and eliminate other Guide 3 disclosure items that overlap with Commission rules or U.S. Generally Accepted Accounting Principles. In addition, the disclosure requirements were added to a new subpart of Regulation S-K and rescinds Guide 3. The ASU did not have a material impact on the Company's consolidated financial statements, but impacted disclosure requirements in the Company's Form 10-K, including: - Distribution of assets, liabilities and stockholders' equity; - Weighted average yield of each maturity category of debt securities not carried at fair value through earnings; - Maturity analysis of the loan portfolio; - Certain credit ratios, including requiring the disclosure of the allowance for loan losses to total loans, nonaccrual loans to total loans, allowance for loan losses to nonaccrual loans, and net charge-offs to average loans by loan category; - Allowance for loan losses by category; and - average deposit rates paid and amount that are uninsured. ASU 2021-04 Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options December 31, 2021 (early adopted and is being applied as of January 1, 2021) Clarifies and reduces diversity in an issuer's accounting for modifications or exchanges of freestanding equity- classified written call options that remain equity- classified. An issuer should measure the effect of a modification as the difference between the fair value of the modified warrant and the fair value of that warrant immediately before modification. The recognition of the modification depends on the nature of the transaction in which a warrant is modified: (i) Equity issuance - recorded as deferred costs of an equity offering; (ii) Debt origination - recorded as a debt discount if held by the lender or debt issuance costs if held by a third party; (iii) Debt modification - recorded as a fee paid to or received from the creditor, if held by a creditor, and as a third party cost if held by a third party; and (iv) All other modifications - recorded as a dividend that reduces retained earnings. The Company had 113,500 warrants outstanding as of December 31, 2021. The amendments in the ASU did not have a material impact on the Company's year-end or interim consolidated financial statements. Standard Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2018-16 Derivative and Hedging (Topic 815) Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes December 31, 2021 (applied as of January 1, 2021) Permit use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes in addition to the UST, the LIBOR swap rate, the OIS rate based on the Fed Funds Effective Rate, and the SIFMA Municipal Swap Rate. The change will apply prospectively for qualifying new or redesignated hedging relationships entered into on or after the date of adoption. The ASU did not have a material impact on the Company's year-end or interim consolidated financial statements. ASU 2018-15 Intangibles-Goodwill and Other- Internal-Use Software December 31, 2021 (applied as of January 1, 2021) 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. The Company elected to apply the change in accounting principle prospectively. A review of third-party, hosting arrangements, including software-as-a-service ("SaaS") arrangements, that were in the implementation stage was performed in 2021 to ensure applicable implementation costs were capitalized and will be amortized over the service period. SaaS arrangements are service contracts providing the Company with the right to access the cloud provider’s application software over the contract period. As such the Company does not receive a software intangible asset at the contract commencement date. A right to receive future access to the supplier’s software does not, at the contract commencement date, give the customer the power to obtain the future economic benefits flowing from the software itself and to restrict others’ access to those benefits The ASU did not have a material impact on the Company's year-end or interim consolidated financial statements. The Company's previous capitalization policies were similar to the ASU requirements. ASU 2017-12 Derivatives and Hedging (Topic 815) Targeted Improvements to Accounting for Hedging Activities December 31, 2021 (applied as of January 1, 2021) Simplifies and expands the eligible hedging strategies for financial and nonfinancial risks. Enhances the transparency of how hedging results are presented and disclosed. Provides partial relief on the timing of certain aspects of hedge documentation and eliminates the requirement to recognize hedge ineffectiveness separately in earnings. During the year ended December 31, 2021, the Company began entering into cash flow hedges. As of December 31, 2021, the total number of cash flow hedges was 5 with an aggregate notional amount of $ 100 million. The amendments in the ASU did not have a material impact on the Company's year-end or interim consolidated financial statements. Standard Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2020-04: Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting June 30, 2020 The ASU provides optional expedients and exceptions to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The ASU only applies to transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The amendments include: (1) Optional expedients to contract modifications that allow the Company to adjust the effective interest rate of receivables and debt, account for lease modifications as a continuation of the existing lease, and remove the requirement to reassess its original conclusions for contract modifications about whether that contract contains an embedded derivative that is clearly and closely related to the economic characteristics and risks of the host contract under Subtopic 815-15, Derivatives and Hedging— Embedded Derivatives; (2) Exceptions to the guidance in Topic 815 related to changes in the critical terms of a hedging relationship due to reference rate reform; and (3) Optional expedients for cash flow and fair value hedges. The Company had more than $ 1 billion in loans tied to LIBOR as of December 31, 2020. The adoption did not have a material accounting impact on the Company’s consolidated financial position or results of operations. Additionally, LIBOR fallback language has been included in key loan provisions of new and renewed loans in preparation for transition from LIBOR to the new benchmark rate when such transition occurs. This standard is expected to ease the administrative burden in accounting for the future effects of reference rate reform. The ASU allows the Company to recognize the modification related to LIBOR as a continuation of the old contract, rather than a cancellation of the old contract resulting in a write off of unamortized fees and creation of a new contract. ASU 2019-12: Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes January 1, 2020 (Early Adoption) The ASU simplifies the accounting for income taxes. Among other changes, the ASU: (1) Removes the exception to the incremental approach for intraperiod tax allocation when there is a loss from continuing operations and income or a gain from other items; (2) Removes the exception to the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year; (3) Requires an entity to recognize a franchise tax that is partially based on income as an income-based tax and account for any incremental amount incurred as a nonincome based tax; and (4) Requires an entity to reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. The amendments in the ASU did not have a material impact on the Company’s tax methodology, processes, or the Company’s financial statements. Standard Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2018-13: Fair Value Measurement (Topic 820): Disclosure Framework January 1, 2020 Improves the effectiveness of disclosures in the notes to financial statements by facilitating clear communication of the information. The amendments modify certain disclosure requirements of fair value measurements in Topic 820, Fair Value Measurement. Entities are no longer required to disclose transfers between Level 1 and Level 2 of the fair value hierarchy or qualitatively disclose the valuation process for Level 3 fair value measurements. The updated guidance requires disclosure of the changes in unrealized gains and losses for the period included in Other Comprehensive Income for recurring Level 3 fair value measurements. Entities are required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. The additional provisions of the guidance should be adopted prospectively. The eliminated requirements should be adopted retrospectively. The adoption did not have a material impact to the Company’s financial statements. No transfers between Level 1 and Level 2 occurred in 2019 or 2020 and the Company did not have any recurring Level 3 fair value measurements that created an unrealized gain or loss in Other Comprehensive Income. In addition, the Company previously disclosed the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. ASU 2017-04: Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment January 1, 2020 (Early Adoption) Eliminates Step 2 from the goodwill impairment test which required entities to compute the implied fair value of goodwill. An entity should perform an annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. On the date of adoption, there was no impact to the Company’s financial statements. The Company’s process for evaluating goodwill impairment was modified to align with the elimination of Step 2. In the second quarter of 2020, the Company performed a Step 0 analysis then a Step 1 analysis and determined that goodwill was fully impaired. ASU 2016-01: Financial Instruments- Overall (Subtopic 825-10) January 2019 Required equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. Emphasized the existing requirement to use exit prices to measure fair value for disclosure purposes and clarifies that entities should not make use of practicability exceptions in determining the fair value of loans. The Company transferred $ 69 thousand from accumulated other comprehensive loss to retained earnings in January 2019. There was no impact to the income statement on the adoption date. Standard Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2018-07: Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting January 2019 Early adoption Expanded the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees, excluding share-based payments used to effectively provide: (i) financing to the issuer or (ii) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The amendments include: (i) grants are measured at grant-date fair value of the equity instruments; (ii) equity-classified nonemployee share-based payment awards are measured at the grant date;(iii) performance based awards are measured based on the probability of satisfying the performance conditions and (iv) in general, non- employee share-based payment awards will continue to be subject to the requirements of ASC 718 unless modified after the good has been delivered, the service has been rendered, any other conditions necessary to earn the right to benefit from the instrument have been satisfied, and the nonemployee is no longer providing goods or services. The Company had 216,960 stock-based awards to non-employees as of the implementation date, including 116,960 performance- based restricted stock units. The adoption of the ASU allowed the Company to: (i) set the fair market value of the non-employee awards as of the adoption date; and (ii) start to expense the performance-based restricted stock units based on the probability of satisfying the performance conditions. Adoption of ASU 2018-07 required the Company to make a one time transfer of $ 2 million from retained earnings to additional paid in capital. In addition, the Company recorded a $ 306 thousand deferred tax asset that was offset with retained earnings to account for the tax impact. The Company will record forfeitures as they occur and base fair market values on the expected term, like the Company’s accounting for employee-based awards. ASU 2014-09: Revenue from Contracts with Customers January 2019 Amended guidance related to revenue from contracts with customers. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Replaced nearly all existing revenue recognition guidance, including industry specific guidance, established a new control based revenue recognition model, changed the basis for deciding when revenue is recognized over time or at a point in time, provided new and more detailed guidance on specific topics and expands and improves disclosures about revenue. The accounting update did not materially impact the financial statements or recognition of revenues. The update did not apply to revenue associated with financial instruments, including loans and securities that are accounted for under other GAAP, which comprises a significant portion of the Company’s revenue stream. In addition, the Company’s noninterest income is generated by customer transactions or through the passage of time and as a result the pattern or timing of income recognition was not impacted.

The obligations are collateralized by securities of U.S. government sponsored enterprises and mortgage-backed securities and such collateral is held by a third-party custodian. The year-to-date average daily balance was $ 2 million and $ 32 million for the years ended December 31, 2021 and 2020, respectively. The securities, mortgage-backed government sponsored residential securities, pledged for customer repurchase agreements were $ 0 and $ 6 million at December 31, 2021 and 2020, respectively. (2) Federal funds purchased include short-term funds that are borrowed from another bank. The Bank is part of a third-party service that allows us to borrow amounts from another bank if the bank has approved us for credit. Federal funds purchased generally have one day maturities. (3) FHLB advances and line of credit are collateralized by a blanket floating lien on certain loans, as well as, unrestricted securities. FHLB advances are at a fixed rate, ranging from 0.37 % to 2.88 % and are subject to restrictions or penalties in the event of prepayment. The FHLB line of credit has a variable interest rate that reprices daily based on FHLB’s cost of funds and matures on May 14, 2022. (4) Federal Reserve borrowings are collateralized by certain available-for-sale securities and certain loans. The Federal Reserve discount window advance rates are variable and based on an established discount rate determined by the Reserve Banks’ board of directors, subject to review and determination by the Board of Governors. The borrowings typically mature in 90 days. (5) On June 30, 2010, the Company assumed a liability with a fair value of $ 1 million related to the assumption of trust preferred securities issued by Leawood Bancshares Statutory Trust I for $ 4 million on September 30, 2005. In 2012, the Company settled litigation related to the trust preferred securities which decreased the principal balance by $ 1.5 million and the recorded balance by approximately $ 400 thousand. The difference between the recorded amount and the contract value of $ 2.5 million is being accreted to the maturity date in 2035. Distributions will be paid on each security at a variable annual rate of interest, equal to LIBOR, plus 1.74 %. (6) Represents the year-end weighted average interest rate.
