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”), a Kansas corporation, was incorporated in December 2017. Prior to incorporation, the Company was registered as a limited liability company under the name CrossFirst Holdings, LLC. The Company is a bank holding company whose principal activities are the ownership and management of its wholly-owned subsidiaries, CrossFirst Bank (the “Bank”) and CFSA, LLC (“CFSA”), which holds title to certain assets. In addition, CrossFirst Investments, Inc. (“CFI”) is a wholly-owned subsidiary of the Bank, which holds investments in marketable securities. 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 and CFSA. 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 notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, filed with the SEC on March 10, 2020. 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. Except for the accounting changes mentioned under “Coronavirus Aid, Relief, and Economic Security Act” and “Change in Accounting Principal” section below, no other significant changes in the accounting policies of the Company occurred since December 31, 2019, the most recent date financial statements were provided within the Company’s Annual Report on Form 10-K. The information contained in the financial statements and footnotes for the period ended December 31, 2019 included in the Company’s 2019 Form 10-K should be referred to in connection with these unaudited interim consolidated financial statements. 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 has 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 and Lease Losses, Investment Securities Impairment, Deferred Tax Asset, and Fair Value of Financial Instruments are particularly susceptible to significant change. Cash Equivalents The Company had $111 million of cash and cash equivalents at the Federal Reserve Bank of Kansas City as of March 31, 2020. The reserve required at March 31, 2020 was $0. In addition, the Company is at times required to place cash collateral with a third party as part of its back-to-back swap agreements. At March 31, 2020, approximately $30 million was required as cash collateral. Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) The CARES Act allows financial institutions to elect not to consider whether loan modifications relating to the COVID-19 pandemic that they make between March 1, 2020 and the earlier of December 31, 2020 or 60 days after the national emergency related to the COVID-19 pandemic ends are troubled debt restructurings (“TDRs”) that would require accounting consequences. The relief can be applied to modifications of loans to borrowers that were not more than 30 days past due as of December 31, 2019. The Company elected the guidance during the first quarter of 2020. The review of loans that meet the criteria is overseen by the Chief Credit Officer. Change in Accounting Principle On January 1, 2020, the Company adopted the Financial Accounting Standards Board Accounting Standard Update (“ASU”) 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, 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. On January 1, 2020, the Company adopted ASU 2019-12, Simplifying the Accounting for Income Taxes, which was applied as of the adoption date. 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 quarter ended March 31, 2020, the Company consolidated the “Other” line item previously included in stockholders’ equity into retained earnings within the Consolidated Balance Sheets and the Consolidated Statements of Stockholders’ Equity. The consolidation was made due to the immateriality of the “Other” line item. The change had no impact on net income or stockholders’ equity. Initial Public Offering On August 19, 2019, the Company completed its initial public offering of common shares. The Company issued and sold 5,750,000 common shares at a public offering price of $14.50 per share. After deducting the underwriting discounts and offering expenses, the Company received total net proceeds of $76 million from the initial public offering. In addition, certain selling stockholders participated in the offering and sold an aggregate of 1,261,589 common shares at a public offering price of $14.50 per share. The Company did not receive any proceeds from the sales of shares by the selling stockholders. On September 17, 2019, the underwriters partially exercised their option to purchase additional shares. The Company issued and sold 844,362 common shares at a public offering price of $14.50 per share. After deducting the underwriting discounts and offering expenses, the Company received total net proceeds of $11 million. As of March 31, 2020, the Company qualified as an emerging growth company (“EGC”) under the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). 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 Company has implemented the following ASUs during 2020: Standard Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2019-12: Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes January 1, 2020 The amendments in the ASU simplify the accounting for income taxes. Among other changes, the ASU: The amendments in the ASU did not have a material impact on the Company’s tax methodology, processes, or the Company’s financial statements. 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 on fair value measurements in Topic 820, Fair Value Measurement. The adoption did not have a material impact to the financial statements. ASU 2017-04: Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment January 1, 2020 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. The adoption did not have an impact to the financial statements, but may accelerate the recognition of goodwill impairment, because it removes a second step required under the old method to determine if goodwill is impaired. The Company has updates to the following ASUs that have not yet been adopted. A complete list of recent, applicable accounting pronouncements was provided in the Company’s latest Annual Report on Form 10-K for the year ended December 31, 2019: Standard Anticipated 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 Effective March 12, 2020 through December 31, 2022. The amendments in this update provide optional expedients and exceptions to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The Company had more than $1 billion in loans tied to LIBOR as of March 31, 2020. The Company is currently unable to determine the financial statement impact related to the ASU, but we anticipate the ASU will simplify modifications executed between the selected start date and December 31, 2020 that are directly related to the LIBOR transition. Specifically, the ASU will allow 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. Standard Anticipated Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2016-13 Financial Instruments-Credit Losses If we maintain our EGC status, the Company is not required to implement this standard until January 2023. The Company will monitor its progress and the requirements related to adoption. 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 has established a committee of individuals from applicable departments to oversee the implementation process. ASU 2016-02 Leases (Topic 842) The Company expects to implement this standard in 2021 if EGC status is maintained. If the Company loses its EGC status in 2020, the Company would be required to implement the ASU as of the beginning of 2020. 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.

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 other-than-temporarily impaired (“OTTI”) at March 31, 2020. Gains and losses on the sale of debt securities are recorded on the trade date and are determined using the specific identification method. Gross gains of $402 thousand and $57 thousand and gross losses of $9 thousand and $4 thousand resulting from sales of available-for-sale securities were realized for the three months ended March 31, 2020 and 2019, respectively. The gross gains as of March 31, 2020, included $75 thousand related to a previously disclosed OTTI municipal security that was settled in 2020. Equity Securities Equity securities consist of Community Reinvestment Act mutual funds. The fair value of the equity securities was $2 million at both March 31, 2020 and December 31, 2019. The following is a summary of the recorded fair value and the unrealized and realized gains and losses recognized in net income on available-for-sale equity securities: Three Months Ended March 31, 2020 2019 (Dollars in thousands) Net gains recognized during the reporting period on equity securities $ 34 $ 26 Less: net gains recognized during the reporting period on equity securities sold during the reporting period — — Unrealized gain recognized during the reporting period on equity securities still held at the reporting date $ 34 $ 26

Loans and Allowance for Loan Losses	Loans and Allowance for Loan Losses Categories of loans at March 31, 2020 and December 31, 2019 include: March 31, 2020 December 31, 2019 (Dollars in thousands) Commercial $ 1,355,723 $ 1,356,817 Energy 398,797 408,573 Commercial real estate 1,084,684 1,024,041 Construction and land development 625,145 628,418 Residential real estate 503,702 398,695 Consumer 43,118 45,163 Gross loans 4,011,169 3,861,707 Less: Allowance for loan losses 51,458 56,896 Less: Net deferred loan fees and costs 8,718 9,463 Net loans $ 3,950,993 $ 3,795,348 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 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: Commercial Energy Commercial Real Estate Construction and Land Development Residential Real Estate Consumer Total (Dollars in thousands) Three months ended March 31, 2020 Allowance for loan losses Beginning balance $ 35,864 $ 6,565 $ 8,085 $ 3,516 $ 2,546 320 $ 56,896 Provision charged to expense 3,271 2,313 4,538 1,505 2,141 182 13,950 Charge-offs (18,077) (1,279) — — — (104) (19,460) Recoveries 71 — — — — 1 72 Ending balance $ 21,129 $ 7,599 $ 12,623 $ 5,021 $ 4,687 $ 399 $ 51,458 Commercial Energy Commercial Real Estate Construction and Land Development Residential Real Estate Consumer Total (Dollars in thousands) Three months ended March 31, 2019 Allowance for loan losses Beginning balance $ 16,584 $ 10,262 $ 6,755 $ 2,475 $ 1,464 $ 286 $ 37,826 Provision charged to expense 5,163 (3,748) 716 110 583 26 2,850 Charge-offs (1,254) — — — — (10) (1,264) Recoveries 13 576 — — — — 589 Ending balance $ 20,506 $ 7,090 $ 7,471 $ 2,585 $ 2,047 $ 302 $ 40,001 Commercial Energy Commercial Real Estate Construction and Land Development Residential Real Estate Consumer Total (Dollars in thousands) March 31, 2020 Ending balance Individually evaluated for impairment $ 3,228 $ 1,224 $ 1,449 $ — $ 189 $ — $ 6,090 Collectively evaluated for impairment $ 17,901 $ 6,375 $ 11,174 $ 5,021 $ 4,498 $ 399 $ 45,368 Allocated to loans: Individually evaluated for impairment $ 71,983 $ 15,703 $ 14,840 $ — $ 5,654 $ 254 $ 108,434 Collectively evaluated for impairment $ 1,283,740 $ 383,094 $ 1,069,844 $ 625,145 $ 498,048 $ 42,864 $ 3,902,735 Ending balance $ 1,355,723 $ 398,797 $ 1,084,684 $ 625,145 $ 503,702 $ 43,118 $ 4,011,169 Commercial Energy Commercial Real Estate Construction and Land Development Residential Real Estate Consumer Total (Dollars in thousands) December 31, 2019 Ending balance Individually evaluated for impairment $ 19,942 $ 1,949 $ 210 $ — $ 197 $ — $ 22,298 Collectively evaluated for impairment $ 15,922 $ 4,616 $ 7,875 $ 3,516 $ 2,349 $ 320 $ 34,598 Allocated to loans: Individually evaluated for impairment $ 70,876 9,744 $ 10,492 $ — $ 2,388 $ — $ 93,500 Collectively evaluated for impairment $ 1,285,941 $ 398,829 $ 1,013,549 $ 628,418 $ 396,307 $ 45,163 $ 3,768,207 Ending balance $ 1,356,817 $ 408,573 $ 1,024,041 $ 628,418 $ 398,695 $ 45,163 $ 3,861,707 Credit Risk Profile The Company analyzes its loan portfolio based on an internal rating category (grades 1 - 8), portfolio segment and payment activity. These categories are utilized to develop the associated allowance for loan losses. A description of the loan grades and segments follows: Loan Grades • Pass & Watch (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 a well-defined weaknesses 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. • 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 and 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 needs, 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 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. • 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.

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 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. 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 March 31, 2020 and December 31, 2019: March 31, 2020 December 31, 2019 (Dollars in thousands) Commercial $ 10,352 $ 32,130 Energy 8,265 4,540 Commercial real estate 5,443 1,063 Construction and land development — — Residential real estate 1,941 1,942 Consumer 254 — Total non-accrual loans $ 26,255 $ 39,675 Troubled Debt Restructurings Restructured loans are those extended to borrowers who are experiencing financial difficulty and who have been granted a concession. The modification of terms typically includes the extension of maturity, reduction or deferment of monthly payment, or reduction of the stated interest rate. The table below presents loans restructured, excluding loans restructured as a result of the COVID-19 pandemic, during the three months ended March 31, 2020 and 2019, including the post-modification outstanding balance and the type of concession made: Three Months Ended March 31, 2020 March 31, 2019 (Dollars in thousands) Commercial - Interest rate reduction $ 3,171 $ — - Reduction of monthly payment — 4,761 Energy - Extension of maturity date 2,340 — Total troubled debt restructurings $ 5,511 $ 4,761 As of March 31, 2020 and December 31, 2019, the Company had $556 thousand and $934 thousand, respectively, in unfunded commitments to borrowers whose terms have been modified in troubled debt restructurings. As of March 31, 2020, 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 enough collateral was obtained to provide an additional commitment.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging	Derivatives and Hedging Derivatives 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. 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 non-performance risk, also known as the credit valuation adjustment, or CVA, was adjusted from a more conservative default methodology to a review of the historical defaults recognized by the Company. Management believes this change better aligns with the Company’s credit methodology and underwriting standards. As of March 31, 2020 and December 31, 2019, the Company had the following outstanding derivatives that were not designated as hedges in qualifying hedging relationships: March 31, 2020 December 31, 2019 Product Number of Instruments Notional Amount Number of Instruments Notional Amount (Dollars in thousands) Back-to-back swaps 58 $ 440,617 56 $ 380,050 The table below presents the fair value of the Company’s derivative financial instruments and their classification on the Balance Sheet as of March 31, 2020 and December 31, 2019: Asset Derivatives Liability Derivatives Balance Sheet March 31, December 31, Balance Sheet March 31, December 31, Location 2020 2019 Location 2020 2019 (Dollars in thousands) Derivatives not designated as hedging instruments Interest rate products Other assets $ 28,041 $ 9,838 Other liabilities $ 28,139 $ 9,907 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.

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 March 31, 2020, the Company and the Bank met all capital adequacy requirements to which they are subject. The capital rules require us 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 Fully Phased-In” 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.

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 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 tables present the fair value measurements of 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 March 31, 2020 and December 31, 2019: March 31, 2020 Fair Value Measurements Using Fair Value Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs (Dollars in thousands) Available-for-sale securities Mortgage-backed - GSE residential $ 149,821 $ — $ 149,821 $ — Collateralized mortgage obligations - GSE residential 118,938 — 118,938 — State and political subdivisions 462,850 — 462,850 — Corporate bonds 1,415 — 1,415 — Mutual funds 2,207 — 2,207 — Derivative assets 28,041 — 28,041 — Derivative liabilities $ 28,139 $ — $ 28,139 $ — December 31, 2019 Fair Value Measurements Using Fair Value Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs (Dollars in thousands) Available-for-sale securities Mortgage-backed - GSE residential $ 152,512 $ — $ 152,512 $ — Collateralized mortgage obligations - GSE residential 129,212 — 129,212 — State and political subdivisions 456,340 — 456,340 — Corporate bonds 1,409 — 1,409 — Mutual funds 2,161 — 2,161 — Derivative assets 9,838 — 9,838 — Derivative liabilities $ 9,907 $ — $ 9,907 $ — Following is a description of the valuation methodologies and inputs used for assets and liabilities measured at fair value on a recurring basis and recognized in the Company’s accompanying consolidated Balance Sheets. Available-for-Sale Securities 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. Such securities are classified in Level 2 of the valuation hierarchy. Derivatives Fair value of the interest rate swaps is obtained from independent pricing services based on quoted market prices for similar derivative contracts. 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 March 31, 2020 and December 31, 2019: March 31, 2020 Fair Value Measurements Using Fair Value Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs (Dollars in thousands) Collateral-dependent impaired loans $ 24,679 $ — $ — $ 24,679 December 31, 2019 Fair Value Measurements Using Fair Value Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs (Dollars in thousands) Collateral-dependent impaired loans $ 20,889 $ — $ — $ 20,889 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. These discounts and estimates are developed by the Office of the Chief Credit Officer by comparison to historical results. Unobservable (Level 3) Inputs The following tables present quantitative information about unobservable inputs used in nonrecurring Level 3 fair value measurements at March 31, 2020 and December 31, 2019: March 31, 2020 Fair Value Valuation Techniques Unobservable Inputs Range (Weighted Average) (Dollars in thousands) Collateral-dependent impaired loans $ 24,679 Market comparable properties Marketability discount 10% - 15% (12%) December 31, 2019 Fair Value Valuation Techniques Unobservable Inputs Range (Weighted Average) (Dollars in thousands) Collateral-dependent impaired loans $ 20,889 Market comparable properties Marketability discount 10% - 15% (12%) The following tables present the estimated fair values of the Company’s financial instruments at March 31, 2020 and December 31, 2019: March 31, 2020 Carrying Fair Value Measurements Amount Level 1 Level 2 Level 3 Total (Dollars in thousands) Financial Assets Cash and cash equivalents $ 158,987 $ 158,987 $ — $ — $ 158,987 Available-for-sale securities 735,231 — 735,231 — 735,231 Loans, net of allowance for loan losses 3,950,993 — — 3,946,203 3,946,203 Restricted equity securities 18,539 — — 18,539 18,539 Interest receivable 16,958 — 16,958 — 16,958 Derivative assets 28,041 — 28,041 — 28,041 $ 4,908,749 $ 158,987 $ 780,230 $ 3,964,742 $ 4,903,959 Financial Liabilities Deposits $ 3,972,822 $ 567,215 $ — $ 3,428,178 $ 3,995,393 Federal funds purchased and repurchase agreements 38,946 — 38,946 — 38,946 Federal Home Loan Bank advances 402,680 — 423,799 — 423,799 Other borrowings 931 — 1,576 — 1,576 Interest payable 3,365 — 3,365 — 3,365 Derivative liabilities 28,139 — 28,139 — 28,139 $ 4,446,883 $ 567,215 $ 495,825 $ 3,428,178 $ 4,491,218 December 31, 2019 Carrying Fair Value Measurements Amount Level 1 Level 2 Level 3 Total (Dollars in thousands) Financial Assets Cash and cash equivalents $ 187,320 $ 187,320 $ — $ — $ 187,320 Available-for-sale securities 741,634 — 741,634 — 741,634 Loans, net of allowance for loan losses 3,795,348 — — 3,810,818 3,810,818 Restricted equity securities 17,278 — — 17,278 17,278 Interest receivable 15,716 — 15,716 — 15,716 Derivative assets 9,838 — 9,838 — 9,838 $ 4,767,134 $ 187,320 $ 767,188 $ 3,828,096 $ 4,782,604 Financial Liabilities Deposits $ 3,923,759 $ 521,826 $ — $ 3,407,012 $ 3,928,838 Federal funds purchased and repurchase agreements 14,921 — 14,921 — 14,921 Federal Home Loan Bank advances 358,743 — 357,859 — 357,859 Other borrowings 921 — 2,147 — 2,147 Interest payable 4,584 — 4,584 — 4,584 Derivative liabilities 9,907 — 9,907 — 9,907 $ 4,312,835 $ 521,826 $ 389,418 $ 3,407,012 $ 4,318,256

The energy portfolio is subdivided into exploration and production for oil and natural gas, which represented approximately 65% and 35%, respectively of the energy portfolio at March 31, 2020. The dramatic decrease in demand for oil and natural gas created by the COVID-19 pandemic put considerable pricing volatility and uncertainty in the market. Depressed prices may strain our customer’s cash flows, lower their liquidity, and decrease property values that could create negative grade migration over the next several quarters. The length of the COVID-19 pandemic disruption and the pace of economic recovery will determine the severity of the grade migration and potential loss impact within the energy portfolio. Information pertaining to the energy portfolio may be found within Note 4: Loans and Allowance for Loan Losses .

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 and CFSA. 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 notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, filed with the SEC on March 10, 2020. 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. Except for the accounting changes mentioned under “Coronavirus Aid, Relief, and Economic Security Act” and “Change in Accounting Principal” section below, no other significant changes in the accounting policies of the Company occurred since December 31, 2019, the most recent date financial statements were provided within the Company’s Annual Report on Form 10-K. The information contained in the financial statements and footnotes for the period ended December 31, 2019 included in the Company’s 2019 Form 10-K should be referred to in connection with these unaudited interim consolidated financial statements. 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 has 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 and Lease Losses, Investment Securities Impairment, Deferred Tax Asset, and Fair Value of Financial Instruments are particularly susceptible to significant change.
Cash Equivalents	Cash EquivalentsThe Company had $111 million of cash and cash equivalents at the Federal Reserve Bank of Kansas City as of March 31, 2020. The reserve required at March 31, 2020 was $0. In addition, the Company is at times required to place cash collateral with a third party as part of its back-to-back swap agreements. At March 31, 2020, approximately $30 million was required as cash collateral.
Changes Affecting Comparability	Changes Affecting ComparabilityFor the quarter ended March 31, 2020, the Company consolidated the “Other” line item previously included in stockholders’ equity into retained earnings within the Consolidated Balance Sheets and the Consolidated Statements of Stockholders’ Equity. The consolidation was made due to the immateriality of the “Other” line item.
Change in Accounting Principle and Recent Accounting Pronouncements	Change in Accounting Principle On January 1, 2020, the Company adopted the Financial Accounting Standards Board Accounting Standard Update (“ASU”) 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, 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. On January 1, 2020, the Company adopted ASU 2019-12, Simplifying the Accounting for Income Taxes, which was applied as of the adoption date. 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 Company has implemented the following ASUs during 2020: Standard Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2019-12: Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes January 1, 2020 The amendments in the ASU simplify the accounting for income taxes. Among other changes, the ASU: The amendments in the ASU did not have a material impact on the Company’s tax methodology, processes, or the Company’s financial statements. 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 on fair value measurements in Topic 820, Fair Value Measurement. The adoption did not have a material impact to the financial statements. ASU 2017-04: Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment January 1, 2020 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. The adoption did not have an impact to the financial statements, but may accelerate the recognition of goodwill impairment, because it removes a second step required under the old method to determine if goodwill is impaired. The Company has updates to the following ASUs that have not yet been adopted. A complete list of recent, applicable accounting pronouncements was provided in the Company’s latest Annual Report on Form 10-K for the year ended December 31, 2019: Standard Anticipated 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 Effective March 12, 2020 through December 31, 2022. The amendments in this update provide optional expedients and exceptions to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The Company had more than $1 billion in loans tied to LIBOR as of March 31, 2020. The Company is currently unable to determine the financial statement impact related to the ASU, but we anticipate the ASU will simplify modifications executed between the selected start date and December 31, 2020 that are directly related to the LIBOR transition. Specifically, the ASU will allow 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. Standard Anticipated Date of Adoption Description Effect on Financial Statements or Other Significant Matters ASU 2016-13 Financial Instruments-Credit Losses If we maintain our EGC status, the Company is not required to implement this standard until January 2023. The Company will monitor its progress and the requirements related to adoption. 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 has established a committee of individuals from applicable departments to oversee the implementation process. ASU 2016-02 Leases (Topic 842) The Company expects to implement this standard in 2021 if EGC status is maintained. If the Company loses its EGC status in 2020, the Company would be required to implement the ASU as of the beginning of 2020. 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.
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.
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 troubled debt restructurings where concessions have been granted to borrowers experiencing financial difficulties. The intent of concessions is to maximize collection.
Non-accrual Loans	Non-accrual Loans Nonperforming loans are loans for which the Company does not record 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. 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. 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	Available-for-Sale Securities 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. Such securities are classified in Level 2 of the valuation hierarchy. Derivatives Fair value of the interest rate swaps is obtained from independent pricing services based on quoted market prices for similar derivative contracts. 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.
