Accounting Policies [Abstract]
Nature of Operations and Summary of Significant Accounting Policies	Nature of Operations and Summary of Significant Accounting Policies Organization and Nature of Operations CrossFirst Bankshares, Inc. (the “Company”) is a bank holding company whose principal activities are the ownership and management of its wholly-owned subsidiary, CrossFirst Bank (the “Bank”). In addition, the Bank has three subsidiaries including CrossFirst Investments, Inc. (“CFI”) that holds investments in marketable securities, CFBSA I, LLC that holds foreclosed assets and CFBSA II, LLC that holds 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; and (vii) Frisco, Texas. During the quarter ended June 30, 2021, the Company entered the Phoenix, Arizona market. 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, CFI, CFBSA I, LLC and CFBSA II, LLC. All significant intercompany accounts and transactions have been eliminated in consolidation. The consolidated interim financial statements are unaudited and certain information and footnote disclosures presented in accordance with GAAP have been condensed or omitted and should be read in conjunction with the Company’s consolidated financial statements and footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 (the “2020 Form 10-K”), filed with the Securities and Exchange Commission (the “SEC”) on February 26, 2021. In the opinion of management, the interim financial statements include all adjustments which are of a normal, recurring nature necessary for the fair presentation of the financial position, results of operations, and cash flows of the Company and the disclosures made are adequate to make the interim financial information not misleading. The consolidated financial statements have been prepared in accordance with GAAP for interim financial information and the instructions to Form 10-Q adopted by the SEC. No significant changes in the accounting policies of the Company occurred since December 31, 2020, the most recent date financial statements were provided within the Company’s 2020 Form 10-K. Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for a full year or any future period. Use of Estimates The Company identified accounting policies and estimates that, due to the difficult, subjective or complex judgments and assumptions inherent in those policies and estimates and the potential sensitivity of the Company’s financial statements to those judgments and assumptions, are critical to an understanding of the Company’s financial condition and results of operations. Actual results could differ from those estimates. In particular, the novel coronavirus (“COVID-19”) pandemic and resulting impacts to economic conditions, as well as adverse impacts to the Company’s operations, may impact future estimates. The allowance for loan losses, deferred tax asset, and fair value of financial instruments are particularly susceptible to significant change. Cash Equivalents The Company had $182 million of cash and cash equivalents at the Federal Reserve Bank of Kansas City as of June 30, 2021. The reserve required at June 30, 2021 was $0. Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) The CARES Act gave financial institutions the right to elect to suspend GAAP principles and regulatory determinations for loan modifications relating to COVID-19 that would otherwise be categorized as Troubled Debt Restructurings (“TDRs”) from March 1, 2020, through December 31, 2020. On December 27, 2020, the Consolidated Appropriations Act, 2021 was signed into law, which extended the period during which the Company may suspend GAAP principles and regulatory determinations for loan modifications relating to COVID-19 that would otherwise be categorized as TDRs through January 1, 2022 or 60 days after the date when the national emergency concerning COVID-19 terminates. The Company elected to apply the guidance starting in the first quarter of 2020. Changes Affecting Comparability Beginning with the quarter ended March 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. 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. Recent Accounting Pronouncements The following table provides information about Accounting Standard Updates (“ASUs”) the Company anticipates to adopt in the future: 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 anticipates an adoption date of January 2022. Requires an entity to utilize a new impairment model known as the current expected credit loss 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 of individuals from applicable departments to oversee the implementation process. The Company completed the third-party software implementation phase that included data capture and portfolio segmentation amongst other items. The Company completed parallel runs in 2019. During the fiscal year ended December 31, 2020, the Company continued to perform parallel runs using 2020 data and continued to recalibrate inputs as necessary. The Company is evaluating the internal control changes that will be necessary to transition to the third-party platform and third-party testing is anticipated later in 2021. At this time, an estimate of the impact cannot be established as the Company continues to evaluate the inputs into the model. The actual impact could be significantly affected by the composition, characteristics, and quality of the underlying loan portfolio at the time of adoption. ASU 2016-02 Leases (Topic 842) The Company expects to implement 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 gathered all potential lease and embedded lease agreements and is evaluating the applicability and impact to the financial statements. The Company’s current operating leases relate primarily to four branch locations. Based on the current leases, the Company anticipates recognizing a lease liability and related right-to-use asset on its balance sheet, with an immaterial impact to its income statement compared to the current lease accounting model. However, the ultimate impact of the standard will depend on the Company's lease portfolio as of the adoption date.

Equity Securities Equity securities consist of a $2 million investment in a Community Reinvestment Act (“CRA”) mutual fund, a $100 thousand private equity investment and an $11 million privately-held security acquired in the fourth quarter of 2020 as part of a debt restructuring. Equity securities are included in “Other assets” on the Consolidated Balance Sheets. The privately-held security was acquired in partial satisfaction of debts previously contracted. 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 during the six-months ended June 30, 2021. The Company is required to make good faith efforts to dispose of the security. The shares may be held for a maximum of five years, subject to a five-year extension that would result in a change to Tier 1 capital.

Loans and Allowance for Loan Losses ("ALLL")	Loans and Allowance for Loan Losses (“ALLL”) Categories of loans at June 30, 2021 and December 31, 2020 include: June 30, 2021 December 31, 2020 (Dollars in thousands) Commercial $ 1,187,824 $ 1,338,757 Energy 326,473 345,233 Commercial real estate 1,208,715 1,179,534 Construction and land development 623,557 563,144 Residential and multifamily real estate 641,669 680,932 Paycheck Protection Program (“PPP”) 197,084 292,230 Consumer 67,003 55,270 Gross loans 4,252,325 4,455,100 Less: Allowance for loan losses 75,493 75,295 Less: Net deferred loan fees and costs 14,381 13,203 Net loans $ 4,162,451 $ 4,366,602 Allowance for Loan Losses The ALLL is established as losses are estimated to have occurred through a provision for loan losses charged against 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 ALLL 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 ALLL consists of allocated and general components. The allocated component relates to loans that are 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 all loans on accrual and is based on historical charge-off experience and expected loss given default derived from the Company’s internal risk rating process and loan categories. 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. The Company evaluates the loan risk grading system definitions, portfolio segment definitions and ALLL methodology on an ongoing basis. No changes to loan definitions, segmentation, or ALLL methodology occurred during the second quarter of 2021. The following tables summarize the activity in the ALLL 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: Commercial Energy Commercial Real Estate Construction and Land Development Residential and Multifamily Real Estate PPP Consumer Total (Dollars in thousands) Three months ended June 30, 2021 Allowance for loan losses Beginning balance $ 23,464 $ 20,292 $ 20,609 $ 3,837 $ 6,056 $ — $ 293 $ 74,551 Provision charged to expense 7,532 (2,443) (1,428) 48 (230) — 21 3,500 Charge-offs (2,566) — — — — — — (2,566) Recoveries 3 — — — — — 5 8 Ending balance $ 28,433 $ 17,849 $ 19,181 $ 3,885 $ 5,826 $ — $ 319 $ 75,493 Commercial Energy Commercial Real Estate Construction and Land Development Residential and Multifamily Real Estate PPP Consumer Total (Dollars in thousands) Three months ended June 30, 2020 Allowance for loan losses Beginning balance $ 21,129 $ 7,599 $ 12,623 $ 5,021 $ 4,687 $ — $ 399 $ 51,458 Provision charged to expense 5,499 10,773 4,276 (2) 370 — 84 21,000 Charge-offs (87) (1,000) — — (189) — — (1,276) Recoveries 2 — — — — — 1 3 Ending balance $ 26,543 $ 17,372 $ 16,899 $ 5,019 $ 4,868 $ — $ 484 $ 71,185 Commercial Energy Commercial Real Estate Construction and Land Development Residential and Multifamily Real Estate PPP Consumer Total (Dollars in thousands) Six months ended June 30, 2021 Allowance for loan losses Beginning balance $ 24,693 $ 18,341 $ 22,354 $ 3,612 $ 5,842 $ — $ 453 $ 75,295 Provision charged to expense 14,547 (492) (3,173) 273 (16) — (139) 11,000 Charge-offs (10,832) — — — — — — (10,832) Recoveries 25 — — — — — 5 30 Ending balance $ 28,433 $ 17,849 $ 19,181 $ 3,885 $ 5,826 $ — $ 319 $ 75,493 Commercial Energy Commercial Real Estate Construction and Land Development Residential and Multifamily Real Estate PPP Consumer Total (Dollars in thousands) Six months ended June 30, 2020 Allowance for loan losses Beginning balance $ 35,864 $ 6,565 $ 8,085 $ 3,516 $ 2,546 $ — $ 320 $ 56,896 Provision charged to expense 8,771 13,085 8,814 1,503 2,511 — 266 34,950 Charge-offs (18,165) (2,278) — — (189) — (104) (20,736) Recoveries 73 — — — — — 2 75 Ending balance $ 26,543 $ 17,372 $ 16,899 $ 5,019 $ 4,868 $ — $ 484 $ 71,185 Commercial Energy Commercial Real Estate Construction and Land Development Residential and Multifamily Real Estate PPP Consumer Total (Dollars in thousands) June 30, 2021 Period end allowance for loan losses allocated to: Individually evaluated for impairment $ 4,166 $ 5,855 $ 2,980 $ — $ — $ — $ — $ 13,001 Collectively evaluated for impairment $ 24,267 $ 11,994 $ 16,201 $ 3,885 $ 5,826 $ — $ 319 $ 62,492 Ending balance $ 28,433 $ 17,849 $ 19,181 $ 3,885 $ 5,826 $ — $ 319 $ 75,493 Allocated to loans: Individually evaluated for impairment $ 33,073 $ 26,591 $ 35,748 $ — $ 4,574 $ — $ 239 $ 100,225 Collectively evaluated for impairment $ 1,154,751 $ 299,882 $ 1,172,967 $ 623,557 $ 637,095 $ 197,084 $ 66,764 $ 4,152,100 Ending balance $ 1,187,824 $ 326,473 $ 1,208,715 $ 623,557 $ 641,669 $ 197,084 $ 67,003 $ 4,252,325 Commercial Energy Commercial Real Estate Construction and Land Development Residential and Multifamily Real Estate PPP Consumer Total (Dollars in thousands) December 31, 2020 Period end allowance for loan losses allocated to: Individually evaluated for impairment $ 1,115 $ 3,370 $ 5,048 $ — $ — $ — $ — $ 9,533 Collectively evaluated for impairment $ 23,578 $ 14,971 $ 17,306 $ 3,612 $ 5,842 $ — $ 453 $ 65,762 Ending balance $ 24,693 $ 18,341 $ 22,354 $ 3,612 $ 5,842 $ — $ 453 $ 75,295 Allocated to loans: Individually evaluated for impairment $ 44,678 26,045 $ 44,318 $ — $ 6,329 $ — $ 244 $ 121,614 Collectively evaluated for impairment $ 1,294,079 $ 319,188 $ 1,135,216 $ 563,144 $ 674,603 $ 292,230 $ 55,026 $ 4,333,486 Ending balance $ 1,338,757 $ 345,233 $ 1,179,534 $ 563,144 $ 680,932 $ 292,230 $ 55,270 $ 4,455,100 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) - The category includes loans that are considered satisfactory. The category 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) - The category includes borrowers that 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) - The category includes borrowers that 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) - The category includes borrowers that exhibit weaknesses inherent in a substandard credit and characteristics 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 - The category 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 - The category 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 - The category includes loans that 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 - The category includes loans that 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 category includes loans that 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 category includes loans that were established by the CARES Act which authorized forgivable loans to small businesses to pay their employees during the COVID-19 pandemic. The loans are 100 percent guaranteed by the SBA and repayment is primarily dependent on the borrower’s cash flow or SBA repayment approval. • Consumer - The category includes 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.

Impaired loans include nonperforming loans but also include loans modified in TDRs 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 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 June 30, 2021 and December 31, 2020: June 30, 2021 December 31, 2020 (Dollars in thousands) Commercial $ 15,957 $ 26,691 Energy 26,504 25,927 Commercial real estate 10,545 19,088 Construction and land development — — Residential and multifamily real estate 1,407 3,101 PPP — — Consumer 239 244 Total non-accrual loans $ 54,652 $ 75,051 Troubled Debt Restructurings 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. The modification of terms typically includes the extension of maturity, reduction or deferment of monthly payment, or reduction of the stated interest rate. For the three- and six-month periods ended June 30, 2021 and 2020, the modifications related to the TDRs below did not impact the ALLL because the loans were previously impaired and evaluated on an individual basis or enough collateral was obtained. The table below presents loans restructured, excluding loans restructured as a result of the COVID-19 pandemic, during the three- and six-month periods ended June 30, 2021 and 2020, including the post-modification outstanding balance and the type of concession made: Three Months Ended Six Months Ended June 30, June 30, June 30, June 30, 2021 2020 2021 2020 (Dollars in thousands) Commercial - Interest rate reduction $ — $ — $ — $ 3,171 Energy - Extension of maturity date — — — 2,340 Residential and multifamily real estate - Payment deferral — 65 — 65 Total troubled debt restructurings $ — $ 65 $ — $ 5,576 The balance of restructured loans, excluding loans restructured as a result of the COVID-19 pandemic, is provided below as of June 30, 2021 and December 31, 2020.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging	Derivatives and HedgingDerivatives not designated as hedges are not speculative and result from a service the Company provides 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. As the interest rate derivatives associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer derivatives and the offsetting derivatives are recognized directly in earnings. As of June 30, 2021 and December 31, 2020, the Company had the following outstanding derivatives that were not designated as hedges in qualifying hedging relationships: June 30, 2021 December 31, 2020 Product Number of Instruments Notional Amount Number of Instruments Notional Amount (Dollars in thousands) Back-to-back swaps 56 $ 568,413 56 $ 515,567 The table below presents the fair value of the Company’s derivative financial instruments and their classification on the Balance Sheet as of June 30, 2021 and December 31, 2020: Asset Derivatives Liability Derivatives Balance Sheet June 30, December 31, Balance Sheet June 30, December 31, Location 2021 2020 Location 2021 2020 (Dollars in thousands) Derivatives not designated as hedging instruments Interest rate products Other assets $ 17,137 $ 24,094 Other liabilities $ 17,372 $ 24,454

Banking Regulation, Risk-Based Information [Abstract]
Regulatory Matters	Regulatory Matters The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Management believes that, as of June 30, 2021, the Company and the Bank met all capital adequacy requirements to which they are subject. The capital rules require the Company to maintain a 2.5% capital conservation buffer with respect to Common Equity Tier I capital, Tier I capital to risk-weighted assets, and total capital to risk-weighted assets, which is included in the column “Minimum Capital Required - Basel III” within the table below. A financial institution with a conservation buffer of less than the required amount is subject to limitations on capital distributions, including dividend payments and stock repurchases, as well as certain discretionary bonus payments to executive officers. The Company’s and the Bank’s actual capital amounts and ratios as of June 30, 2021 and December 31, 2020 are presented in the following table: Actual Minimum Capital Required - Basel III Required to be Considered Well Capitalized Amount Ratio Amount Ratio Amount Ratio (Dollars in thousands) June 30, 2021 Total Capital to Risk-Weighted Assets Consolidated $ 671,355 13.7 % $ 515,660 10.5 % N/A N/A Bank 640,383 13.0 515,444 10.5 $ 490,899 10.0 % Tier I Capital to Risk-Weighted Assets Consolidated 609,792 12.4 417,439 8.5 N/A N/A Bank 578,846 11.8 417,264 8.5 392,719 8.0 Common Equity Tier 1 to Risk-Weighted Assets Consolidated 608,806 12.4 343,773 7.0 N/A N/A Bank 578,846 11.8 343,629 7.0 319,085 6.5 Tier I Capital to Average Assets Consolidated 609,792 10.8 225,540 4.0 N/A N/A Bank $ 578,846 10.3 % $ 225,492 4.0 % $ 281,866 5.0 % December 31, 2020 Total Capital to Risk-Weighted Assets Consolidated $ 656,806 13.1 % $ 527,486 10.5 % N/A N/A Bank 611,533 12.2 527,217 10.5 $ 502,111 10.0 % Tier I Capital to Risk-Weighted Assets Consolidated 593,865 11.8 427,012 8.5 N/A N/A Bank 548,615 10.9 426,794 8.5 401,689 8.0 Common Equity Tier 1 to Risk-Weighted Assets Consolidated 592,902 11.8 351,657 7.0 N/A N/A Bank 548,615 10.9 351,478 7.0 326,372 6.5 Tier I Capital to Average Assets Consolidated 593,865 10.8 219,550 4.0 N/A N/A Bank $ 548,615 10.0 % $ 219,441 4.0 % $ 274,302 5.0 %

The PBSAs 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 the six months ended June 30, 2021, the Company granted 63,631 PBSAs. The performance metrics include three-year cumulative, adjusted earnings per share and relative total shareholder return. The following table summarizes the status of and changes in the PBSAs: Performance-Based Stock Awards Number of Shares Weighted-Average Grant Date Fair Value Unvested, January 1, 2021 231,631 $10.51 Granted 63,631 12.89 Incremental performance shares 2,424 10.00 Vested (77,426) 11.31 Forfeited 0 0.00 Unvested, June 30, 2021 220,260 $10.90 Unrecognized stock-based compensation related to the PBSAs issued through June 30, 2021 was $717 thousand and is expected to be recognized over 2.7 years.

Fair Value Disclosures [Abstract]
Disclosures about Fair Value of Financial Instruments	Disclosures about Fair Value of Financial Instruments Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. 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: 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. 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 June 30, 2021 and December 31, 2020: 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. Level 2 Note 3: Securities Derivatives Fair value of the interest rate swaps is obtained from independent pricing services based on quoted market prices for similar derivative contracts. Level 2 Note 5: Derivatives and Hedging Nonrecurring Measurements The following tables present assets measured at fair value on a nonrecurring basis and the level within the fair value hierarchy in which the fair value measurements fall at June 30, 2021 and December 31, 2020: June 30, 2021 Fair Value Measurements Using Fair Value Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Unobservable Inputs (Dollars in thousands) Collateral-dependent impaired loans $ 55,419 $ — $ — $ 55,419 Foreclosed assets held-for-sale $ 1,718 $ — $ — $ 1,718 December 31, 2020 Fair Value Measurements Using Fair Value Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Unobservable Inputs (Dollars in thousands) Collateral-dependent impaired loans $ 55,454 $ — $ — $ 55,454 Foreclosed assets held-for-sale $ 2,347 $ — $ — $ 2,347 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. 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 Office of the Chief Credit Officer. Appraisals are reviewed for accuracy and consistency by the Office of 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.

Nature of Operations and Summ_2

Nature of Operations and Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Jun. 30, 2021
Accounting Policies [Abstract]
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, CFI, CFBSA I, LLC and CFBSA II, LLC. All significant intercompany accounts and transactions have been eliminated in consolidation. The consolidated interim financial statements are unaudited and certain information and footnote disclosures presented in accordance with GAAP have been condensed or omitted and should be read in conjunction with the Company’s consolidated financial statements and footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 (the “2020 Form 10-K”), filed with the Securities and Exchange Commission (the “SEC”) on February 26, 2021. In the opinion of management, the interim financial statements include all adjustments which are of a normal, recurring nature necessary for the fair presentation of the financial position, results of operations, and cash flows of the Company and the disclosures made are adequate to make the interim financial information not misleading. The consolidated financial statements have been prepared in accordance with GAAP for interim financial information and the instructions to Form 10-Q adopted by the SEC. No significant changes in the accounting policies of the Company occurred since December 31, 2020, the most recent date financial statements were provided within the Company’s 2020 Form 10-K. Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for a full year or any future period.
Use of Estimates	Use of Estimates The Company identified accounting policies and estimates that, due to the difficult, subjective or complex judgments and assumptions inherent in those policies and estimates and the potential sensitivity of the Company’s financial statements to those judgments and assumptions, are critical to an understanding of the Company’s financial condition and results of operations. Actual results could differ from those estimates. In particular, the novel coronavirus (“COVID-19”) pandemic and resulting impacts to economic conditions, as well as adverse impacts to the Company’s operations, may impact future estimates. The allowance for loan losses, deferred tax asset, and fair value of financial instruments are particularly susceptible to significant change.
Cash Equivalents	Cash EquivalentsThe Company had $182 million of cash and cash equivalents at the Federal Reserve Bank of Kansas City as of June 30, 2021. The reserve required at June 30, 2021 was $0.
Changes Affecting Comparability	Changes Affecting Comparability Beginning with the quarter ended March 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.
Recent Accounting Pronouncements	Recent Accounting Pronouncements The following table provides information about Accounting Standard Updates (“ASUs”) the Company anticipates to adopt in the future: 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 anticipates an adoption date of January 2022. Requires an entity to utilize a new impairment model known as the current expected credit loss 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 of individuals from applicable departments to oversee the implementation process. The Company completed the third-party software implementation phase that included data capture and portfolio segmentation amongst other items. The Company completed parallel runs in 2019. During the fiscal year ended December 31, 2020, the Company continued to perform parallel runs using 2020 data and continued to recalibrate inputs as necessary. The Company is evaluating the internal control changes that will be necessary to transition to the third-party platform and third-party testing is anticipated later in 2021. At this time, an estimate of the impact cannot be established as the Company continues to evaluate the inputs into the model. The actual impact could be significantly affected by the composition, characteristics, and quality of the underlying loan portfolio at the time of adoption. ASU 2016-02 Leases (Topic 842) The Company expects to implement 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 gathered all potential lease and embedded lease agreements and is evaluating the applicability and impact to the financial statements. The Company’s current operating leases relate primarily to four branch locations. Based on the current leases, the Company anticipates recognizing a lease liability and related right-to-use asset on its balance sheet, with an immaterial impact to its income statement compared to the current lease accounting model. However, the ultimate impact of the standard will depend on the Company's lease portfolio as of the adoption date.
Impaired Loans	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 TDRs where concessions have been granted to borrowers experiencing financial difficulties. The intent of concessions is to maximize collection.
Allowance for Loan Losses	Allowance for Loan Losses The ALLL is established as losses are estimated to have occurred through a provision for loan losses charged against 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 ALLL 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 ALLL consists of allocated and general components. The allocated component relates to loans that are 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 all loans on accrual and is based on historical charge-off experience and expected loss given default derived from the Company’s internal risk rating process and loan categories. 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.
Non-accrual Loans	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.
Troubled Debt Restructurings	Troubled Debt RestructuringsRestructured 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. The modification of terms typically includes the extension of maturity, reduction or deferment of monthly payment, or reduction of the stated interest rate.
Fair Value Measurement	Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. 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: 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. 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 Office of the Chief Credit Officer. Appraisals are reviewed for accuracy and consistency by the Office of 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 Office of 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.
