SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES UMB Financial Corporation is a bank holding company, which offers a wide range of banking and other financial services to its customers through its branches and offices in the states of Missouri, Kansas, Colorado, Illinois, Oklahoma, Texas, Arizona, Nebraska, Iowa, Pennsylvania, South Dakota, Indiana, Utah, Minnesota, California, and Wisconsin. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements. These estimates and assumptions also impact reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Following is a summary of the more significant accounting policies to assist the reader in understanding the financial presentation. Consolidation The Company and its wholly owned subsidiaries are included in the Consolidated Financial Statements (references hereinafter to the “Company” in these Notes to Consolidated Financial Statements include wholly owned subsidiaries). Intercompany accounts and transactions have been eliminated in consolidation. Revenue Recognition Interest on loans and securities is recognized based on rate times the principal amount outstanding. This includes the impact of amortization of premiums and discounts. Interest accrual is discontinued when, in the opinion of management, the likelihood of collection becomes doubtful. Other noninterest income is recognized when performance obligations are satisfied. Cash and cash equivalents Cash and cash equivalents include Cash and due from banks and amounts due from the FRB. Cash on hand, cash items in the process of collection, and amounts due from correspondent banks are included in Cash and due from banks. Amounts due from the FRB are interest-bearing for all periods presented and are included in the Interest-bearing due from banks line on the Company’s Consolidated Balance Sheets. This table provides a summary of cash and cash equivalents as presented on the Consolidated Statements of Cash Flows as of December 31, 2020 and 2019 (in thousands) : December 31, 2020 2019 Due from the FRB $ 3,066,928 $ 1,196,212 Cash and due from banks 430,638 472,958 Cash and cash equivalents at end of year $ 3,497,566 $ 1,669,170 Also included in the Interest-bearing due from banks line, but not considered cash and cash equivalents are interest-bearing accounts held at other financial institutions, which totaled $43.1 million and $29.3 million at December 31, 2020 and 2019, respectively. Loans and Loans Held for Sale As further discussed below, the Company adopted ASU 2016-13, “Measurement of Credit Losses on Financial Instruments,” on January 1, 2020. The revised accounting policies are described below. Loans are classified by the portfolio segments of commercial and industrial, specialty lending, commercial real estate, consumer real estate, consumer, credit cards, and leases and other. A loan is considered to be collateral dependent when management believes it is probable that it will be unable to collect all principal and interest due according to the contractual terms of the loan. If a loan is collateral dependent, the Company records a valuation allowance equal to the carrying amount of the loan in excess of the present value of the estimated future cash flows discounted at the loan’s effective rate, based on the loan’s observable market price or the fair value of the collateral. A loan is accounted for as a troubled debt restructuring when a concession had been granted to a debtor experiencing financial difficulties. The Company’s modifications generally include interest rate adjustments, and amortization and maturity date extensions. These modifications allow the debtor short-term cash relief to allow them to improve their financial condition. Restructured loans are considered to be collateral dependent and are individually evaluated for credit loss as part of the allowance for credit loss analysis. Loans, including those that are considered to be collateral dependent or a troubled debt restructuring, are evaluated regularly by management. Loans are considered delinquent when payment has not been received within 30 days of its contractual due date. The adequacy of the ACL on loans is based on management’s judgment and continuous evaluation of the pertinent factors underlying the credit quality inherent in the loan portfolio. Consideration of quantitative and qualitative factors relevant to each specific segmentation of loans includes lifetime historical loss experience, the impact of the current economic environment, reasonable and supportable forecasts, and detailed analysis of loans determined to be collateral dependent. The actual losses incurred over the lifetime of the portfolio, notwithstanding such considerations, however, could differ from the amounts estimated by management. The Company maintains an allowance for off-balance sheet credit exposures, to address the credit risk to which the Company is exposed via a contractual obligation to extend credit, unless that obligation is unconditionally cancelable by the Company. The allowance for off-balance sheet credit exposure is included in the Accrued expenses and taxes line item in the Consolidated Balance Sheets. In order to maintain the allowance for off-balance sheet items at an appropriate level, a provision to increase or reduce the allowance is included in the Company’s Consolidated Statements of Income. The allowance for off-balance sheet credit exposure is calculated by applying portfolio segment expected credit loss rates to the expected amount to be funded. Loans held for sale are carried at the lower of aggregate cost or market value. Loan fees (net of certain direct loan origination costs) on loans held for sale are deferred until the related loans are sold or repaid. Gains or losses on loan sales are recognized at the time of sale and determined using the specific identification method. Prior to the adoption of ASU 2016-13, loans were classified by the portfolio segments of commercial, real estate, consumer, and leases. The portfolio segments were further disaggregated into loan classes of commercial, asset-based, factoring, commercial credit card, real estate – construction, real estate – commercial, real estate – residential, real estate – HELOC, consumer – credit card, consumer – other, and leases. A loan was considered to be impaired when management believed it was probable that it would be unable to collect all principal and interest due according to the contractual terms of the loan. Additionally, the adequacy of the allowance for loan losses was based on management’s evaluation of the inherent losses that had been incurred within the existing portfolio of loans. Further, a reserve to address the risk of loss associated with loan contingencies was separately maintained. This reserve was assessed by dividing the contingencies into pools of similar loan commitments and applying to factors to each pool. The gross amount of contingent exposure was first multiplied by a potential factor to estimate the degree to which the unused commitments might reasonably be expected to be used in a time of high usage. The resultant figure was then multiplied by a factor to estimate the risk of loss assuming funding of these loans. The potential loss estimates for each segment of the portfolio were added to arrive at a total potential loss estimate that was used to set the reserve. Securities Debt securities available for sale principally include U.S. Treasury and agency securities, GSE mortgage-backed securities, certain securities of state and political subdivisions, and corporates. Debt securities classified as available for sale are measured at fair value. Unrealized holding gains and losses are excluded from earnings and reported in Accumulated other comprehensive income (AOCI) until realized. Securities held to maturity are carried at amortized historical cost , net of the allowance for credit losses, based on management’s intention, and the Company’s ability to hold them to maturity. The Company classifies certain securities of state and political subdivisions as held to maturity. Trading securities, acquired for subsequent sale to customers, are carried at fair value. Market adjustments, fees and gains or losses on the sale of trading securities are considered to be a normal part of operations and are included in trading and investment banking income. Equity-method investments The Company accounts for certain other investments using equity-method accounting. For equity securities without readily determinable fair values, the Company’s proportionate share of the income or loss is recognized on a one-quarter lag. When transparency in pricing exists, other investments are considered equity securities with readily determinable fair values. Goodwill and Other Intangibles Goodwill is tested for impairment annually and more frequently whenever events or changes in circumstances indicate that it is more likely than not that the fair value of a reporting unit is less than its carrying value. To test goodwill for impairment, the Company performs a qualitative assessment of each reporting unit. If the Company determines, on the basis of qualitative factors, that the fair value of the reporting unit is more likely than not greater than the carrying amount, the quantitative impairment test is not required. Otherwise, the Company compares the fair value of its reporting units to their carrying amounts to determine if an impairment exists and the amount of impairment loss. An impairment loss is measured as the excess of the carrying value of a reporting unit’s goodwill over its fair value. No goodwill impairments were recognized in 2020, 2019, or 2018. Other intangible assets, which relate to core deposits, non-compete agreements, and customer relationships, are amortized over their useful life. Intangible assets are evaluated for impairment when events or circumstances dictate. No intangible asset impairments were recognized in 2020, 2019, or 2018. The Company does not have any indefinite lived intangible assets. Premises and Equipment Premises and equipment are stated at cost less accumulated depreciation, which is computed primarily on the straight line method. Premises are depreciated over 15 to 40 year lives, while equipment is depreciated over lives of 3 to 20 years. Gains and losses from the sale of Premises and equipment are included in Other noninterest income and Other noninterest expense, respectively. Impairment of Long-Lived Assets Long-lived assets, including Premises and equipment, are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset or group of assets may not be recoverable. The impairment review includes a comparison of future cash flows expected to be generated by the asset or group of assets to their current carrying value. If the carrying value of the asset or group of assets exceeds expected cash flows (undiscounted and without interest charges), an impairment loss is recognized to the extent the carrying value exceeds fair value. No impairments were recognized in 2020, 2019, or 2018. Income Taxes The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are measured based on the differences between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the periods in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. The provision for deferred income taxes represents the change in the deferred income tax accounts during the year excluding the tax effect of the change in net unrealized gain (loss) on securities available for sale. The Company records deferred tax assets to the extent these assets will more likely than not be realized. All available evidence is considered in making such determination, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and recent financial operations. A valuation allowance is recorded for the portion of deferred tax assets that are not more-likely-than-not to be realized , and any changes to the valuation allowance are recorded in income tax expense. The Company records the financial statement effects of an income tax position when it is more likely than not, based on the technical merits, that it will be sustained upon examination. A tax position that meets the more-likely-than-not recognition threshold is measured and recorded as the largest amount of tax benefit that is greater than 50 percent likely of being realized upon ultimate settlement with a taxing authority. Previously recognized tax positions are derecognized in the first period in which it is no longer more likely than not that the tax position will be sustained. The benefit associated with previously unrecognized tax positions are generally recognized in the first period in which the more-likely-than-not threshold is met at the reporting date, the tax matter is ultimately settled through negotiation or litigation, or when the related statute of limitations for the relevant taxing authority to examine and challenge the tax position has expired. The recognition, derecognition and measurement of tax positions are based on management’s best judgment given the facts, circumstances and information available at the reporting date. The Company recognizes accrued interest related to unrecognized tax benefits in interest expense and penalties in other noninterest expense. Accrued interest and penalties are included within the related liability lines in the Consolidated Balance Sheets. For the year ended December 31, 2020, the Company has recognized an immaterial amount in interest and penalties related to the unrecognized tax benefits. Derivatives The Company records all derivatives on the Consolidated Balance Sheets at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Currently, three of the Company’s derivatives are designated in qualifying hedging relationships. The remainder of the Company’s derivatives are not designated in qualifying hedging relationships, as the derivatives are not used to manage risks within the Company’s assets or liabilities. All changes in fair value of the Company’s non-designated derivatives and fair value hedges are recognized directly in earnings. Changes in fair value of the Company’s cash flow hedges are recognized in AOCI and are reclassified to earnings when the hedged transaction affects earnings. Per Share Data Basic income per share is computed based on the weighted average number of shares of common stock outstanding during each period. Diluted year-to-date income per share includes the dilutive effect of 205,959, 310,614, and 435,800 shares issuable upon the exercise of stock options, nonvested restricted shares, and nonvested restricted stock units, granted by the Company that were outstanding at December 31, 2020, 2019, and 2018, respectively. Certain options, restricted stock and restricted stock units issued under employee benefit plans were excluded from the computation of diluted earnings per share because they were anti-dilutive. Outstanding options, restricted stock and restricted stock units of 198,671, 114,130, and 125,765 for the years ended December 31, 2020, 2019, and 2018, respectively, were excluded from the computation of diluted income per share because their inclusion would have been anti-dilutive. Accounting for Stock-Based Compensation The Company measures the cost of employee services received in exchange for an award of equity instruments based on the fair value of the award on the date of the grant. For stock options, restricted stock, and service-based restricted stock unit awards, the grant date fair value is estimated using either an option-pricing model which is consistent with the terms of the award or an observed market price, if such a price exists. For performance-based restricted stock unit awards, the grant date fair value is based on the quoted price of the Company’s common stock on the grant date less the present value of expected dividends not received during the vesting period. Such cost is generally recognized over the vesting period during which an employee is required to provide service in exchange for the award and, in some cases, when performance metrics are met. The Company accounts f or forfeitures of stock-based compensation on an actual basis as they occur .

Accounting Changes And Error Corrections [Abstract]
NEW ACCOUNTING PRONOUNCEMENTS	2. NEW ACCOUNTING PRONOUNCEMENTS Revenue Recognition In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers.” The ASU replaced most existing revenue recognition guidance in U.S. GAAP when it became effective. In August 2015, the FASB issued ASU No. 2015-14, which deferred the effective date of ASU No. 2014-09 to annual reporting periods that begin after December 15, 2017. In March, April, and May 2016, the FASB issued implementation amendments to the May 2014 ASU (collectively, the amended guidance). The amended guidance affects any entity that enters into contracts with customers to transfer goods and services, unless those contracts are within the scope of other standards. The amended guidance specifically excludes interest income, as well as other revenues associated with financial assets and liabilities, including loans, leases, securities, and derivatives. The amended guidance permits the use of either the full retrospective approach or a modified retrospective approach. The Company adopted the amended guidance using the modified retrospective approach on January 1, 2018. The adoption of this guidance had no impact on the Company’s Consolidated Financial Statements, except for additional financial statement disclosures. See Note 13, “Revenue Recognition” for related disclosures. Financial Instruments In January 2016, the FASB issued ASU No. 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities.” The amendment is intended to address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The amendments in this update were adopted on January 1, 2018. Upon adoption, the Company recorded a cumulative effect adjustment to the Company’s Consolidated Balance Sheets of $132 thousand as an increase to the opening balance of total shareholders’ equity. Leases In February 2016, the FASB issued ASU No. 2016-02, “Leases” – ASC Topic 842. In January, July, and December 2018 and March 2019, the FASB issued implementation amendments to the February 2016 ASU (collectively, the amended guidance). The amended guidance changed the accounting treatment of leases, in that lessees recognize most leases on-balance sheet. This increased reported assets and liabilities, as lessees are required to recognize a right-of-use asset along with a lease liability, measured on a discounted basis. The amended guidance allows an entity to choose either the effective date, or the beginning of the earliest comparative period presented in the financial statements, as its date of initial application. The Company adopted the amended guidance on January 1, 2019, using the effective date as the date of initial application. Adoption of the amended guidance resulted in the recording of a right-of-use asset of $58.2 million and a lease liability of $63.0 million to its Consolidated Balance Sheets as of January 1, 2019. The most significant effects of the adoption of the amended guidance are additional financial statement disclosures. See Note 8, “Premises, Equipment, and Leases” for related disclosures. Extinguishments of Liabilities In March 2016, the FASB issued ASU No. 2016-04, “Recognition of Breakage for Certain Prepaid Stored-Value Products.” The amendment is intended to reduce the diversity in practice related to the recognition of breakage. Breakage refers to the portion of a prepaid stored-value product, such as a gift card, that goes unused wholly or partially for an indefinite period of time. This amendment requires that breakage be accounted for consistent with the breakage guidance within ASU No. 2014-09, “Revenue from Contracts with Customers.” The amendments in this update were adopted January 1, 2018 in conjunction with the adoption of ASU No. 2014-09, and the adoption had no impact on the Company’s Consolidated Financial Statements. Statement of Cash Flows In August 2016, the FASB issued ASU 2016-15 “Classification of Certain Receipts and Cash Payments.” This amendment adds to and clarifies existing guidance regarding the classification of certain cash receipts and payments in the statement of cash flows with the intent of reducing diversity in practice with respect to eight types of cash flows. The amendments in this update require full retrospective adoption. The amendments in this update were adopted on January 1, 2018 and did not have an impact on the Company’s Consolidated Statement of Cash Flows. Derivatives and Hedging In August 2017, the FASB issued ASU 2017-12, “Targeted Improvements to Accounting for Hedging Activities.” The purpose of this updated guidance is to better align financial reporting for hedging activities with the economic objectives of those activities. The amendments in this update were adopted on January 1, 2018. Upon adoption, the Company recorded a cumulative effect adjustment to the Company’s Consolidated Balance Sheets of $13 thousand as an increase to the opening balance of total shareholders’ equity. Comprehensive Income In February 2018, the FASB issued ASU No. 2018-02, “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” Under existing U.S. GAAP, the effects of changes in tax rates and laws on deferred tax balances are recorded as a component of income tax expense in the period in which the law was enacted. When deferred tax balances related to items originally recorded in AOCI are adjusted, certain tax effects become stranded in AOCI. This amendment allows a reclassification from AOCI to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act (the Tax Act), and requires certain disclosures about stranded tax effects. The amendments in this update were adopted using a security-by-security approach on January 1, 2018. Upon adoption, the Company reclassified stranded tax effects totaling $ 12.9 million from AOCI to retained earnings. Credit Losses In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments.” In April and November 2019, the FASB issued implementation amendments to the June 2016 ASU (collectively, the amended guidance). The amended guidance replaced the current incurred loss methodology for recognizing credit losses with a current expected credit loss model, which requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. The amended guidance broadened the information that an entity must consider in developing its expected credit loss estimates. Additionally, the updates amended the accounting for credit losses for available-for-sale debt securities and purchased financial assets with a more-than-insignificant amount of credit deterioration since origination. The amended guidance required enhanced disclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of a company’s loan portfolio. The Company adopted the amended guidance on January 1, 2020 using a modified retrospective approach for adoption. Results for the reporting periods beginning after December 31, 2019 are presented under ASC Topic 326, Financial Instruments – Credit Losses , while prior period amounts continue to be presented in accordance with previously applicable GAAP. Upon adoption, the Company recorded a cumulative effect adjustment to the Company’s Consolidated Balance Sheets of $9.0 million as an increase to the allowance for credit losses and $7.0 million as a reduction to retained earnings, net of deferred tax balances. See Note 3, “Loans and Allowance for Credit Losses” for related disclosures.

LOANS AND ALLOWANCE FOR CREDIT LOSSES	3. LOANS AND ALLOWANCE FOR CREDIT LOSSES The Company adopted the CECL methodology for measuring credit losses as of January 1, 2020 using a modified retrospective approach for adoption. All disclosures as of and for the year ended December 31, 2020 are presented in accordance with ASC 326, Financial Instruments – Credit Losses Loan Origination/Risk Management The Company has certain lending policies and procedures in place that are designed to minimize the level of risk within the loan portfolio. Diversification of the loan portfolio manages the risk associated with fluctuations in economic conditions. Authority levels are established for the extension of credit to ensure consistency throughout the Company. It is necessary that policies, processes and practices implemented to control the risks of individual credit transactions and portfolio segments are sound and adhered to. The Company maintains an independent loan review department that reviews and validates the risk assessment on a continual basis. Management regularly evaluates the results of the loan reviews. The loan review process complements and reinforces the risk identification and assessment decisions made by lenders and credit personnel, as well as the Company’s policies and procedures. Commercial and industrial loans are underwritten after evaluating and understanding the borrower’s ability to operate profitably and prudently expand its business. Commercial loans are made based on the identified cash flows of the borrower and on the underlying collateral provided by the borrower. The cash flows of the borrower, however, may not be as expected and the collateral securing these loans may fluctuate in value. Most commercial loans are secured by the assets being financed or other business assets such as accounts receivable or inventory and may incorporate a personal guarantee. In the case of loans secured by accounts receivable, the availability of funds for the repayment of these loans may be substantially dependent on the ability of the borrower to collect amounts from its customers. Specialty lending loans include Asset-based and Factoring loans. Asset-based loans are offered primarily in the form of revolving lines of credit to commercial borrowers that do not generally qualify for traditional bank financing. Asset-based loans are underwritten based primarily upon the value of the collateral pledged to secure the loan, rather than on the borrower’s general financial condition. The Company utilizes pre-loan due diligence techniques, monitoring disciplines, and loan management practices common within the asset-based lending industry to underwrite loans to these borrowers. Factoring loans provide working capital through the purchase and/or financing of accounts receivable to borrowers in the transportation industry and to commercial borrowers that do not generally qualify for traditional bank financing. Commercial real estate loans are subject to underwriting standards and processes similar to commercial loans, in addition to those of real estate loans. These loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Commercial real estate lending typically involves higher loan principal amounts, and the repayment of these loans is largely dependent on the successful operation of the property securing the loan or the business conducted on the property securing the loan. The Company requires that an appraisal of the collateral be made at origination and on an as-needed basis, in conformity with current market conditions and regulatory requirements. The underwriting standards address both owner and non-owner occupied real estate. Also included in Commercial real estate are Construction loans that are underwritten using feasibility studies, independent appraisal reviews, sensitivity analysis or absorption and lease rates, and financial analysis of the developers and property owners. Construction loans are based upon estimates of costs and value associated with the complete project. Construction loans often involve the disbursement of substantial funds with repayment substantially dependent on the success of the ultimate project. Sources of repayment for these types of loans may be pre-committed permanent loans, sales of developed property or an interim loan commitment from the Company until permanent financing is obtained. These loans are closely monitored by on-site inspections and are considered to have higher risks than other real estate loans due to their repayment being sensitive to interest rate changes, governmental regulation of real property, economic conditions, and the availability of long-term financing. Consumer real estate loans, including residential real estate and home equity loans, are underwritten based on the borrower’s loan-to-value percentage, collection remedies, and overall credit history. Consumer loans are underwritten based on the borrower’s repayment ability. The Company monitors delinquencies on all of its consumer loans and leases. The underwriting and review practices combined with the relatively small loan amounts that are spread across many individual borrowers, minimizes risk. Consumer loans and leases that are 90 days past due or more are considered non-performing. Credit cards include both commercial and consumer credit cards. Commercial credit cards are generally unsecured and are underwritten with criteria similar to commercial loans, including an analysis of the borrower’s cash flow, available business capital, and overall creditworthiness of the borrower. Consumer credit cards are underwritten based on the borrower’s repayment ability. The Company monitors delinquencies on all of its consumer credit cards and periodically reviews the distribution of FICO scores relative to historical periods to monitor credit risk on its consumer credit card loans. Credit risk is a potential loss resulting from nonpayment of either the primary or secondary exposure. Credit risk is mitigated with formal risk management practices and a thorough initial credit-granting process including consistent underwriting standards and approval process. Control factors or techniques to minimize credit risk include knowing the client, understanding total exposure, analyzing the client and debtor’s financial capacity, and monitoring the client’s activities. Credit risk and portions of the portfolio risk are managed through concentration considerations, average risk ratings, and other aggregate characteristics.

The Company has ceased the recognition of interest on loans with a carrying value of $87.8 million and $56.3 million at December 31, 2020 and 2019, respectively. Restructured loans totaled $10.8 million and $19.8 million at December 31, 2020 and 2019, respectively. Loans 90 days past due and still accruing interest amounted to $2.0 million and $2.1 million at December 31, 2020 and 2019, respectively. All interest accrued but not received for loans placed on nonaccrual is reversed against interest income. There was an insignificant amount of interest reversed related to loans on nonaccrual during 2020.

The total amount of accrued interest is excluded from the amortized cost basis of loans presented above. Further, the Company has elected not to measure an allowance for credit losses for accrued interest receivable. Credit Quality Indicators As part of the on-going monitoring of the credit quality of the Company’s loan portfolio, management tracks certain credit quality indicators including trends related to the risk grading of specified classes of loans, net charge-offs, non-performing loans, and general economic conditions. The Company utilizes a risk grading matrix to assign a rating to each of its commercial, commercial real estate, and construction real estate loans. Changes in credit risk are monitored on a continuous basis and changes in risk ratings are made when identified. The loan ratings are summarized into the following categories: Non-watch list, Watch, Special Mention, Substandard, and Doubtful. Any loan not classified in one of the categories described below is considered to be a Non-watch list loan. A description of the general characteristics of the loan rating categories is as follows: • Watch – This rating represents credit exposure that presents higher than average risk and warrants greater than routine attention by Company personnel due to conditions affecting the borrower, the borrower’s industry or the economic environment. These conditions have resulted in some degree of uncertainty that results in higher than average credit risk. These loans are considered pass-rated credits. • Special Mention – This rating reflects a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or the borrower’s credit position at some future date. The rating is not adversely classified and does not expose an institution to sufficient risk to warrant adverse classification. • Substandard – This rating represents an asset inadequately protected by the current sound worth and paying capacity of the borrower or of the collateral pledged, if any. Assets so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. Loans in this category are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Loss potential, while existing in the aggregate amount of substandard assets, does not have to exist in individual assets classified as substandard. • Doubtful – This rating represents an asset that has all the weaknesses inherent in an asset classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, based on currently existing facts, conditions and values, highly questionable and improbable. The possibility of loss is extremely high, but because of certain important and reasonably specific pending factors, which may work to the advantage of strengthening the asset, its classification as an estimated loss is deferred until its more exact status may be determined. Pending factors include proposed merger, acquisition, liquidation procedures, capital injection, or perfecting liens. Commercial and industrial A discussion of the credit quality indicators that impact each type of collateral securing Commercial and industrial loans is included below: Equipment, accounts receivable, and inventory General commercial and industrial loans are secured by working capital assets and non-real estate assets. The general purpose of these loans is for financing capital expenditures and current operations for commercial and industrial entities. These assets are short-term in nature. In the case of accounts receivable and inventories, the repayment of debt is reliant upon converting assets into cash or through goods and services being sold and collected. Collateral based-risk is due to aged short-term assets, which can be indicative of underlying issues with the borrower and lead to the value of the collateral being overstated. Agriculture Agricultural loans are secured by non-real estate agricultural assets. These include shorter-term assets such as equipment, crops, and livestock. The risks associated with loans to finance crops or livestock include the borrower’s ability to successfully raise and market the commodity. Adverse weather conditions and other natural perils can dramatically affect farmers’ or ranchers’ production and ability to service debt. Volatile commodity prices present another significant risk for agriculture borrowers. Market price volatility and production cost volatility can affect both revenues and expenses. Overdrafts Commercial overdrafts are typically short-term and unsecured. Some commercial borrowers tie their overdraft obligation to their line of credit, so any draw on the line of credit will satisfy the overdraft. Based on the factors noted above for each type of collateral, the Company assigns risk ratings to borrowers based on their most recently assessed financial position.

The purpose of these loans is for financing current operations for commercial customers. The repayment of debt is reliant upon collection of the accounts receivable within 30 to 90 days or converting assets into cash or through goods and services being sold and collected. The Company tracks each individual borrower credit risk based on their loan to collateral position. Any borrower position where the underlying value of collateral is below the fair value of the loan is considered out-of-margin and inherently higher risk. Factoring General factoring loans are secured by accounts receivable. The purpose of these loans is for financing current operations for trucking or other commercial customers. The repayment of debt is reliant upon collection of the accounts receivable within 30 to 90 days. The Company tracks each individual borrower’s credit risk based on their loan to collateral position. To assess credit risk, the portfolio is separated into two tiers and a specifically impaired category. Tier 1 are loans that have not experienced collateral coverage rates falling below an internally tracked threshold at any time during their relationship history. The internal threshold is lower than each customers’ actual contractual collateral coverage ratio. Tier 2 are loans that have experienced collateral coverage rates falling below the same internally tracked threshold during their relationship history. Loans evaluated for impairment are loans that have either experienced collateral coverage rates falling below an internally tracked threshold during their relationship history, have balances that are greater than an internally tracked threshold, or are on non-accrual. The combination of these categories has created an associated allowance to this portfolio of $ million as of December 31, 2020.

These loans are often longer tenured and susceptible to multiple economic cycles. The loans rely on the owner-occupied operations to service debt which cover a broad spectrum of industries. Real estate debt can carry a significant amount of leverage for a borrower to maintain. Non-owner-occupied Non-owner-occupied loans are secured by commercial real estate. These loans are often longer tenured and susceptible to multiple economic cycles. The key element of risk in this type of lending is the cyclical nature of real estate markets. Although national conditions affect the overall real estate industry, the effect of national conditions on local markets is equally important. Factors such as unemployment rates, consumer demand, household formation, and the level of economic activity can vary widely from state to state and among metropolitan areas. In addition to geographic considerations, markets can be defined by property type. While all sectors are influenced by economic conditions, some sectors are more sensitive to certain economic factors than others. Farmland Farmland loans are secured by real estate used for agricultural purposes such as crop and livestock production. Assets used as collateral are long-term assets that carry the ability to have longer amortizations and maturities. Longer terms carry the risk of added susceptibility to market conditions. The limited purpose of some Agriculture-related collateral affects credit risk because such collateral may have limited or no other uses to support values when loan repayment problems emerge. 5+ Multi-family 5+ multi-family loans are secured by a multi-family residential property. The primary risks associated with this type of collateral are largely driven by economic conditions. The national and local market conditions can change with unemployment rates or competing supply of multi-family housing. Tenants may not be able to afford their housing or have better options and this can result in increased vacancy. Rents may need to be lowered to fill apartment units. Increased vacancy and lower rental rates not only drive the borrower’s ability to repay debt but also contribute to how the collateral is valued. 1-4 Family construction 1-4 family construction loans are secured by 1-4 family residential real estate and are in the process of construction or improvements being made. The predominant risk inherent to this portfolio is the risk associated with a borrower’s ability to successfully complete a project on time and within budget. Market conditions also play an important role in understanding the risk profile. Risk from adverse changes in market conditions from the start of development to completion can result in deflated collateral values General construction General construction loans are secured by commercial real estate in process of construction or improvements being made and their repayment is dependent on the collateral’s completion. Construction lending presents unique risks not encountered in term financing of existing real estate. The predominant risk inherent to this portfolio is the risk associated with a borrower’s ability to successfully complete a project on time and within budget. Commercial properties under construction are susceptible to market and economic conditions . D emand from prospective customers may erode after construction begins because of a general economic slowdown or an increase in the supply of competing properties . Based on the factors noted above for each type of collateral, the Company assigns risk ratings to borrowers based on their most recently assessed financial position.

The primary risk is the borrower’s inability to repay debt. Revolving notes are often associated with HELOCs that can be secured by real estate without a 1st lien priority. Collateral is susceptible to market volatility impacting home values or economic downturns. First lien: 1-4 family First lien 1-4 family loans are secured by a first lien on 1-4 family residential property. These term loans carry longer maturities and amortizations. The longer tenure exposes the borrower to multiple economic cycles, coupled with longer amortizations that result in smaller principal reduction early in the life of the loan. Collateral is susceptible to market volatility impacting home values. Junior lien: 1-4 family Junior lien 1-4 family loans are secured by a junior lien on 1-4 family residential property. The Company’s primary risk is the borrower’s inability to repay debt and not being in a first lien position. Collateral is susceptible to market volatility impacting home values or economic downturns. A borrower is considered non-performing if the Company has ceased the recognition of interest and the loan is placed on non-accrual. Charge-offs and borrower performance are tracked on a loan origination vintage basis. Certain vintages, based on their maturation cycle, could be at higher risk due to collateral-based risk factors.

The primary risk associated with this collateral is related to market volatility and the value of the underlying financial assets. Auto Direct consumer auto loans are secured by new and used consumer vehicles. The primary risk with this collateral class is the rate at which the collateral depreciates. Other This category includes Other consumer l oan s made to an individual. The primary risk for this category is for those loans where the loan is unsecured. This collateral type also includes other unsecured lending such as consumer overdrafts. A borrower is considered non-performing if the Company has ceased the recognition of interest and the loan is placed on non-accrual. Charge-offs and borrower performance are tracked on a loan origination vintage basis. Certain vintages, based on their maturation cycle, could be at higher risk due to collateral-based risk factors.

The U.S. Treasury, U.S. Agency, and GSE mortgage-backed securities are all considered to be agency-backed securities with no risk of loss as they are either explicitly or implicitly guaranteed by the U.S. government. The changes in fair value in the agency-backed portfolios are solely driven by change in interest rates caused by changing economic conditions. The Company has no knowledge of any underlying credit issues and the cash flows underlying the debt securities have not changed and are not expected to be impacted by changes in interest rates. For the State and political subdivision portfolio, the majority of the Company’s holdings are in general obligation bonds, which have a very low historical default rate due to issuers generally having unlimited taxing authority to service the debt. For both the State and political and Corporate portfolios, the Company has a robust process for monitoring credit risk, including both pre-purchase and ongoing post-purchase credit reviews and analysis. The Company monitors credit ratings of all bond issuers in these segments and reviews available financial data, including market and sector trends. As of December 31, 2020, there is no ACL related to the Company’s available - for - sale securities as the decline in fair value did not result from credit issues .

At December 31, 2020, the Company is required to have minimum common equity tier 1, tier 1, and total capital ratios of 4.5%, 6.0% and 8.0%, respectively. The Company’s actual ratios at that date were 12.10%, 12.10% and 14.26%, respectively. The Company is required to have a minimum leverage ratio of 4.0%, and the leverage ratio at December 31, 2020, was 8.37%. As of December 31, 2020, the most recent notification from the OCC categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well-capitalized the Bank must maintain total risk-based, tier 1 risk-based, common equity tier 1, and tier 1 leverage ratios of 10.0%, 8.0%, 6.5%, and 5.0%, respectively. There are no conditions or events that have occurred since the receipt of the most recent notification that management believes have changed the Bank’s categorization. In addition, under amendments to the BHCA introduced by the Dodd-Frank Act and commonly known as the Volcker Rule, the Company and its subsidiaries are subject to extensive limits on proprietary trading and on owning or sponsoring hedge funds and private-equity funds. The limits on proprietary trading are largely focused on purchases or sales of financial instruments by a banking entity as principal primarily for the purpose of short-term resale, benefitting from actual or expected short-term price movements, or realizing short-term arbitrage profits. The limits on owning or sponsoring hedge funds and private-equity funds are designed to ensure that banking entities generally maintain only small positions in managed or advised funds and are not exposed to significant losses arising directly or indirectly from them. The Volcker Rule also provides for increased capital charges, quantitative limits, rigorous compliance programs, and other restrictions on permitted proprietary trading and fund activities, including a prohibition on transactions with a covered fund that would constitute a covered transaction under Sections 23A and 23B of the Federal Reserve Act. The fund activities of the Company and its subsidiaries are in conformance with the Volcker Rule .

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
EMPLOYEE BENEFITS	11. EMPLOYEE BENEFITS The Company has a discretionary noncontributory profit sharing plan, which features an employee stock ownership plan. This plan is for the benefit of substantially all eligible officers and employees of the Company and its subsidiaries. The Company has accrued and anticipates making a discretionary payment of $2.0 million in March 2021, for 2020. A $2.0 million contribution was paid in 2020, for 2019. A $1.5 million contribution was paid in 2019, for 2018. The Company has a qualified 401(k) profit sharing plan that permits participants to make contributions by salary deduction, to which the Company makes matching contributions. The Company recognized expense related to matching contributions of $11.0 million, $10.6 million, and $8.8 million for the years ended December 31, 2020, 2019 and 2018, respectively. The Company recognized $0.6 million, $1.3 million, and $1.5 million in expense related to outstanding stock options and $3.4 million, $6.9 million, and $8.2 million in expense related to outstanding restricted stock grants for the years ended December 31, 2020, 2019, and 2018, respectively. The Company also recognized $10.5 million, $6.0 million, and $807 thousand in expense related to outstanding restricted stock unit grants for the years ended December 31, 2020, 2019 and 2018, respectively. The Company had $46 thousand of unrecognized compensation expense related to the outstanding stock options, $2.2 million of unrecognized compensation expense related to outstanding restricted stock, and $13.3 million of unrecognized compensation expense related to outstanding restricted stock unit grants at December 31, 2020. Long-Term Incentive Compensation Plan At the April 26, 2005 shareholders’ meeting, the shareholders of the Company approved the UMB Financial Corporation Long-Term Incentive Compensation Plan (LTIP) which became effective as of January 1, 2005. The LTIP permits the issuance to selected officers of the Company service-based restricted stock grants, performance-based restricted stock grants and non-qualified stock options. Service-based restricted stock grants contain a service requirement. The performance-based restricted grants contain performance and service requirements. The non-qualified stock option grants contain a service requirement. At the April 23, 2013 shareholders’ meeting, the shareholders of the Company approved amendments to the LTIP Plan, including increasing the number of shares of the Company’s stock reserved for issuance under the Plan from 5.25 million shares to 7.44 million shares. Additionally, the shareholders approved increasing the maximum benefits any one eligible employee may receive under the plan during any one fiscal year from $1 million to $2 million taking into account the value of all stock options and restricted stock received. The service-based restricted stock grants contain a service requirement with varying vesting schedules. The majority of these grants issued prior to 2016 utilize a vesting schedule in which 50% of the shares vest after three years of service, 75% after four years of service and 100% after five years of service. The majority of these grants issued in 2016 and beyond utilize a vesting schedule in which 50% of the shares vest after two years of service, 75% after three years of service and 100% after four years of service. Certain other grants utilize vesting schedules in which the grants vest ratably over the requisite service period or contain a three-year cliff vesting. The performance-based restricted stock grants contain a service and a performance requirement. The performance requirement is based on a predetermined performance requirement over a three-year The dividends on service and performance-based restricted stock grants are treated as two separate transactions. First, cash dividends are paid on the restricted stock. Those cash dividends are then paid to purchase additional shares of restricted stock. Dividends earned as additional shares of restricted stock have the same terms as the associated grant. The dividends paid on the stock are recorded as a reduction to retained earnings, similar to all dividend transactions. The table below discloses the status of the service-based restricted shares during 2020: Number of Shares Weighted Average Grant Date Fair Value Service-Based Restricted Stock Nonvested - December 31, 2019 210,538 $ 66.65 Granted — — Canceled (7,345 ) 72.11 Vested (136,895 ) 63.30 Nonvested - December 31, 2020 66,298 $ 72.98 As of December 31, 2020, there was $2.2 million of unrecognized compensation cost related to the nonvested shares. The cost is expected to be recognized over a period of 1.0 years.

The Company’s senior executive officers regularly evaluate Business Segment financial results produced by the Company’s internal reporting system in deciding how to allocate resources and assess performance for individual Business Segments. Prior to 2020, the Company had the following four Business Segments: Commercial Banking, Institutional Banking, Personal Banking, and Healthcare Services. In the first quarter of 2020, the Company merged the Healthcare Services segment into the Institutional Banking segment to better reflect how the core businesses, products and services are currently being evaluated by management. The Company’s Healthcare Services leadership structure and financial performance assessments are now included in the Institutional Banking segment, and accordingly, the reportable segments were realigned to reflect these changes. The Company’s reportable Business Segments include certain corporate overhead, technology and service costs that are allocated based on methodologies that are applied consistently between periods. For comparability purposes, amounts in all periods are based on methodologies in effect at December 31, 2020. Previously reported results have been reclassified in this filing to conform to the current organizational structure.

The performance obligations related to this revenue include items such as performing full bond trustee service administration, investment advisory services, custody and record-keeping services, and fund administrative and accounting services. These fees are part of long-term contractual agreements and the performance obligations are satisfied upon completion of service and fees are generally a fixed flat monthly rate or based on a percentage of the account’s market value per the contract with the customer. These fees are primarily recorded within the Company’s Institutional and Personal Banking segments.

The vast majority of this revenue is recognized in accordance with ASC 320, Securities , and is out of the scope of ASC 606. A portion of trading and investment banking represents fees earned for management fees, commissions, and underwriting of corporate bond issuances. The performance obligations related to these fees include reviewing the credit worthiness of the customer, ensuring appropriate regulatory approval and participating in due diligence. The fees are fixed per the bond prospectus and the performance obligations are satisfied upon registration approval of the bonds by the applicable regulatory agencies. Revenue is recognized at the point in time upon completion of service and when approval is granted by the regulators. Service charges on deposits – Service charges on deposit accounts represent monthly analysis fees recognized for the services related to customer deposit accounts, including account maintenance and depository transactions processing fees. Commercial Banking and Institutional Banking depository accounts charge fees in accordance with the customer’s pricing schedule while Personal Banking account holders are generally charged a flat service fee per month. Deposit service charges for the healthcare accounts included in the Institutional Banking segment are priced according to either standard pricing schedules with individual account holders or according to service agreements between the Company and employer groups or third-party administrators. The Company satisfies the performance obligation related to providing depository accounts monthly as transactions are processed and deposit service charge revenue is recorded monthly. These fees are recognized within all Business Segments. Insurance fees and commissions – Insurance fees and commissions includes all insurance-related fees earned, including commissions for individual life, variable life, group life, health, group health, fixed annuity, and variable annuity insurance contracts. The performance obligations related to these revenues primarily represent the placement of insurance policies with the insurance company partners. The fees are based on the contracts with insurance company partners and the performance obligations are satisfied when the terms of the policy have been agreed to and the insurance policy becomes effective. Brokerage fees – Brokerage fees represent income earned related to providing brokerage transaction services, including commissions on equity and commodity trades, and fees for investment management, advisory and administration. The performance obligations related to transaction services are executing the specified trade and are priced according to the customer’s fee schedule. Such income is recognized at a point in time as the trade occurs and the performance obligation is fulfilled. The performance obligations related to investment management, advisory and administration include allocating customer assets across a wide range of mutual funds and other investments, on-going account monitoring and re-balancing of the portfolio. These performance obligations are satisfied over time and the related revenue is calculated monthly based on the assets under management of each customer. All material performance obligations are satisfied as of the end of each accounting period. Bankcard fees – Bankcard fees primarily represent income earned from interchange revenue from MasterCard and Visa for the Company’s processing of debit, credit, HSA, and flexible spending account transactions. Additionally, the Company earns income and incentives related to various referrals of customers to card programs. The performance obligation for interchange revenue is the processing of each transaction through the Company’s access to the banking system. This performance obligation is completed for each individual transaction and income is recognized per transaction in accordance with interchange rates established by MasterCard and Visa. The performance obligations for various referral and incentive programs include either referring customers to certain card products or issuing exclusively branded cards for certain customer segments. The pricing of these incentive and referral programs are in accordance with the agreement with the individual card partner. These performance obligations are completed as the referrals are made or over a period of time when the Company is exclusively issuing branded cards. For the years ended December 31, 2020, 2019 and 2018, the Company also has approximately $30.0 million, $38.1 million, and $36.0 million of expense, respectively, recorded within the Bankcard fees line on the Company’s Consolidated Statements of Income related to rebates and rewards programs that are outside of the scope of ASC 606.

Other income – The Company recognizes other miscellaneous income through a variety of other revenue streams, the most material of which include letter of credit fees, certain loan origination fees, gains on the sale of assets, derivative income, and bank-owned and company-owned life insurance income. These revenue streams are outside of the scope of ASC 606 and are recognized in accordance with the applicable U.S. GAAP. The remainder of Other income is primarily earned through transactions with personal banking customers, including wire transfer service charges, stop payment charges, and fees for items like money orders and cashier’s checks. The performance obligations of these types of fees are satisfied as transactions are completed and revenue is recognized upon transaction execution according to established fee schedules with the customers. The Company had no material contract assets, contract liabilities, or remaining performance obligations as of December 31, 2020 or 2019. Total receivables from revenue recognized under the scope of ASC 606 were $62.1 million and $58.0 million as of December 31, 2020 and December 31, 2019, respectively.

During 2018, the Company entered into an agreement with BAML to repurchase an aggregate of $50.0 million of the Company’s common stock through an ASR. Under the ASR, the Company repurchased a total of 780,321 shares. The final settlement of the transactions under the ASR occurred in December 2018. Additionally, during 2020, the Company entered into an agreement with BAML to repurchase an aggregate of $30.0 million of the Company’s common stock through an ASR. Under the ASR, the Company repurchased a total of 653,498 shares. The final settlement of the transactions under the ASR occurred in the second quarter of 2020. Other than purchases pursuant to the ASR, all share purchases pursuant to the Repurchase Authorizations are intended to be within the scope of Rule 10b-18 promulgated under the Exchange Act. Rule 10b-18 provides a safe harbor for purchases in a given day if the Company satisfies the manner, timing and volume conditions of the rule when purchasing its own common shares. The Company has not made any repurchase of its securities other than pursuant to the Repurchase Authorizations. Basic earnings per share are computed by dividing income available to common shareholders by the weighted average number of shares outstanding during the year. Diluted earnings per share gives effect to all potential common shares that were outstanding during the year. The shares used in the calculation of basic and diluted earnings per share, are shown below: For the Years Ended December 31, 2020 2019 2018 Weighted average basic common shares outstanding 48,137,791 48,779,263 49,334,937 Dilutive effect of stock options and restricted stock 205,959 310,614 435,800 Weighted average diluted common shares outstanding 48,343,750 49,089,877 49,770,737

Commitments And Contingencies Disclosure [Abstract]
COMMITMENTS, CONTINGENCIES AND GUARANTEES	15. COMMITMENTS, CONTINGENCIES AND GUARANTEES In the normal course of business, the Company is a party to financial instruments with off-balance-sheet risk in order to meet the financing needs of its customers and to reduce its own exposure to fluctuations in interest rates. These financial instruments include commitments to extend credit, commercial letters of credit, standby letters of credit, and futures contracts. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the Consolidated Balance Sheets. The contract or notional amount of those instruments reflects the extent of involvement the Company has in particular classes of financial instruments. Many of the commitments expire without being drawn upon; therefore, the total amount of these commitments does not necessarily represent the future cash requirements of the Company. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instruments for commitments to extend credit, commercial letters of credit, and standby letters of credit is represented by the contract or notional amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the agreement. These conditions generally include, but are not limited to, each customer being current as to repayment terms of existing loans and no deterioration in the customer’s financial condition. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. The interest rate is generally a variable rate. If the commitment has a fixed interest rate, the rate is generally not set until such time as credit is extended. For credit card customers, the Company has the right to change or terminate terms or conditions of the credit card account at any time. Since a large portion of the commitments and unused credit card lines are never actually drawn upon, the total commitment amount does not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on an individual basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation. Collateral pledged by customers varies but may include accounts receivable, inventory, real estate, plant and equipment, stock, securities and certificates of deposit. Commercial letters of credit are issued specifically to facilitate trade or commerce. Under the terms of a commercial letter of credit, as a general rule, drafts will be drawn when the underlying transaction is consummated as intended. Standby letters of credit are conditional commitments issued by the Company payable upon the non-performance of a customer’s obligation to a third party. The Company issues standby letters of credit for terms ranging from three months to six years. The Company generally requires the customer to pledge collateral to support the letter of credit. The maximum liability to the Company under standby letters of credit at December 31, 2020 and 2019, was $346.6 million and $299.9 million, respectively. As of December 31, 2020 and 2019, standby letters of credit totaling $3.8 million and $3.7 million, respectively, were with related parties to the Company. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities. The Company holds collateral supporting those commitments when deemed necessary. Collateral varies but may include such items as those described for commitments to extend credit. Futures contracts are contracts for delayed delivery of securities or money market instruments in which the seller agrees to make delivery at a specified future date, of a specified instrument, at a specified yield. Risks arise from the possible inability of counterparties to meet the terms of their contracts and from movement in securities values and interest rates. Instruments used in trading activities are carried at fair value and gains and losses on futures contracts are settled in cash daily. Any changes in the fair value are recognized in trading and investment banking income. The Company uses contracts to offset interest rate risk on specific securities held in the trading portfolio. As of December 31, 2020 and 2019, there were no notional amounts outstanding for these contracts. There were no open futures contract positions during the year ended December 31, 2020 or 2019. There was no net futures activity for the year ended December 31, 2020. Net futures activity resulted in gains of $5 thousand for the year ended December 31, 2019. There was no net futures activity for the year ended December 31, 2018. The Company controls the credit risk of its futures contracts through credit approvals, limits and monitoring procedures. The Company also enters into foreign exchange contracts on a limited basis. For operating purposes, the Company maintains certain balances in foreign banks. Foreign exchange contracts are purchased on a monthly basis to avoid foreign exchange risk on these foreign balances. The Company will also enter into foreign exchange contracts to facilitate foreign exchange needs of customers. The Company will enter into a contract to buy or sell a foreign currency at a future date only as part of a contract to sell or buy the foreign currency at the same future date to a customer. During 2020, contracts to purchase and to sell foreign currency averaged approximately $21.0 million compared to $18.4 million during 2019. The net gains on these foreign exchange contracts for 2020, 2019 and 2018 were $1.9 million, $1.8 million and $2.1 million, respectively. With respect to group concentrations of credit risk, most of the Company’s business activity is with customers in the states of Missouri, Kansas, Colorado, Oklahoma, Nebraska, Arizona, Illinois, and Texas. At December 31, 2020, the Company did not have any significant credit concentrations in any particular industry. The following table summarizes the Company’s off-balance sheet financial instruments as described above (in thousands): Contract or Notional Amount December 31, 2020 2019 Commitments to extend credit for loans (excluding credit card loans) $ 8,851,333 $ 7,409,338 Commitments to extend credit under credit card loans 3,472,339 3,188,905 Commercial letters of credit 3,160 4,460 Standby letters of credit 346,617 299,933 Forward contracts 51,273 58,287 Spot foreign exchange contracts 680 1,980 Allowance for Credit Losses on Off-Balance Sheet Credit Exposure The Company estimates expected credit losses over the contractual period in which the Company is exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancelable by the Company. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over its estimated life. The estimate is based on expected utilization rates by portfolio segment. Utilization rates are influenced by historical trends and current conditions. The expected utilization rates are applied to the total commitment to determine the expected amount to be funded. The allowance for off-balance sheet credit exposure is calculated by applying portfolio segment expected credit loss rates to the expected amount to be funded. The following categories of off-balance sheet credit exposures have been identified: Revolving Lines of Credit: includes commercial, construction, agricultural, personal, and home-equity. Risk inherent to revolving lines of credit often are related to the susceptibility of an individual or business experiencing unpredictable cash flow or financial troubles, thus leading to payment default. During these financial troubles, the borrower could have less than desirable assets collateralizing the revolving line of credit. The financial strain the borrower is experiencing could lead to drawing against the line without the ability to pay the line down. Non-Revolving Lines of Credit: include commercial and personal. Lines that do not carry a revolving feature are generally associated with a specific expenditure or project, such as to purchase equipment or the construction of real estate. The predominate risk associated with non-revolving lines is the diversion of funds for other expenditures. If the funds get diverted, the contributory value to collateral suffers. Letters of Credit: includes standby letters of credit. Generally, a standby letter of credit is established to provide assurance to the beneficiary that the applicant will perform certain obligations arising out of a separate transaction between the beneficiary and the applicant. These obligations might be the performance of a service or delivery of a product If the obligations are not met, it gives the beneficiary the right to draw on the letter of credit. As of December 31, 2020, the ACL for off-balance sheet credit exposures was $5.6 million and was recorded in the Accrued expenses and taxes line of the Company’s Consolidated Balance Sheets. Provision for off-balance sheet credit exposures of $2.6 million was recorded for the year ended December 31, 2020 and was recorded in the Provision for credit losses line of the Company’s Consolidated Statements of Income.

Periodically, the Company is subject to examinations by various taxing authorities that may give rise to differing interpretations of these laws. Upon examination, agreement of tax liabilities between the Company and the multiple tax jurisdictions in which the Company files tax returns may ultimately be different. The Company is in the examination process with the Internal Revenue Service for tax years 2014 and 2015 and with one state taxing authority for tax years 2016, 2017, and 2018. The Company believes the aggregate amount of any additional liabilities that may result from these examinations, if any, will not have a material adverse effect on the financial condition, results of operations, or cash flows of the Company. Deferred income taxes result from differences between the carrying value of assets and liabilities measured for financial reporting and the tax basis of assets and liabilities for income tax return purposes. The significant components of deferred tax assets and liabilities are reflected in the following table (in thousands): December 31, 2020 2019 Deferred tax assets: Loans, principally due to allowance for credit losses $ 52,583 $ 23,765 Equity-based compensation 6,293 5,809 Accrued expenses 19,878 12,471 Deferred compensation 14,830 14,234 Miscellaneous 6,471 6,499 Total deferred tax assets before valuation allowance 100,055 62,778 Valuation allowance (3,278 ) (2,332 ) Total deferred tax assets 96,777 60,446 Deferred tax liabilities: Net unrealized gain on securities available for sale (97,434 ) (29,668 ) Securities (13,462 ) (23 ) Land, buildings and equipment (41,339 ) (32,382 ) Original issue discount (1,969 ) (2,455 ) Partnership investments (6,948 ) (2,091 ) Trust preferred securities (7,538 ) (7,833 ) Intangibles (15,215 ) (12,503 ) Miscellaneous (8,430 ) (3,669 ) Total deferred tax liabilities (192,335 ) (90,624 ) Net deferred tax liability $ (95,558 ) $ (30,178 ) Included in the miscellaneous deferred tax assets line item above are state net operating loss carryforwards of approximately $1.1 million as of December 31, 2020. Most of these net operating losses expire at various times between 2020 and 2040 and some have an indefinite carryforward. The Company has a full valuation allowance for a majority of these state net operating losses as they are not expected to be realized. In addition, the Company has a valuation allowance of $2.2 million to reduce certain other state deferred tax assets to the amount of tax benefit management believes it will more likely than not realize. The net deferred tax liability is included in the Accrued expenses and taxes line of the Company’s Consolidated Balance Sheets. The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction and various states. With few exceptions, the Company is no longer subject to U.S. federal, state and local income tax examinations by tax authorities for tax years prior to 2014 in the jurisdictions in which it files. Liabilities Associated With Unrecognized Tax Benefits The gross amount of unrecognized tax benefits totaled $6.7 million and $5.8 million at December 31, 2020 and 2019, respectively. The total amount of unrecognized tax benefits, net of associated deferred tax benefit, that would impact the effective tax rate, if recognized, would be $5.3 million and $4.6 million at December 31, 2020 and December 31, 2019, respectively. The unrecognized tax benefits relate to state tax positions that have a corresponding federal tax benefit. While it is expected that the amount of unrecognized tax benefits will change in the next twelve months, the Company does not expect this change to have a material impact on the financial condition, results of operations, or cash flows of the Company. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands): December 31, 2020 2019 Unrecognized tax benefits - opening balance $ 5,802 $ 4,859 Gross decreases - tax positions in prior period (96 ) (434 ) Gross increases - current-period tax positions 1,656 1,882 Lapse of statute of limitations (645 ) (505 ) Unrecognized tax benefits - ending balance $ 6,717 $ 5,802

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	18. DERIVATIVES AND HEDGING ACTIVITIES Risk Management Objective of Using Derivatives The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of its assets and liabilities. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to the Company’s loans and borrowings. The Company also has interest rate derivatives that result from a service provided to certain qualifying customers and, therefore, are not used to manage interest rate risk of the Company’s assets or liabilities. The Company has entered into an offsetting position for each of these derivative instruments with a matching instrument from another financial institution in order to minimize its net risk exposure resulting from such transactions. Fair Values of Derivative Instruments on the Consolidated Balance Sheets The table below presents the fair value of the Company’s derivative financial instruments as of December 31, 2020 and 2019. The Company’s derivative assets and derivative liabilities are located within Other assets and Other liabilities, respectively, on the Company’s Consolidated Balance Sheets. Derivative fair values are determined using valuation techniques including discounted cash flow analysis on the expected cash flows from each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves, foreign exchange rates, and implied volatilities. The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees. This table provides a summary of the fair value of the Company’s derivative assets and liabilities as of December 31, 2020 and December 31, 2019 : Derivative Assets Derivative Liabilities December 31, December 31, Fair Value 2020 2019 2020 2019 Interest Rate Products: Derivatives not designated as hedging instruments $ 103,506 $ 47,458 $ 9,375 $ 5,997 Derivatives designated as hedging instruments 48 7,818 — — Total $ 103,554 $ 55,276 $ 9,375 $ 5,997 Fair Value Hedges of Interest Rate Risk The Company is exposed to changes in the fair value of certain of its fixed-rate assets and liabilities due to changes in the benchmark interest rate, LIBOR. Interest rate swaps designated as fair value hedges involve making fixed rate payments to a counterparty in exchange for the Company receiving variable rate payments over the life of the agreements without the exchange of the underlying notional amount. As of December 31, 20 20 and 201 9 , the Company had one interest rate swap that was designated as a fair value hedge of interest rate risk associated with the Company’s fixed rate loan assets. This swap had a notional amount of $ million and $ million as of December 31, 20 20 and 201 9 , respectively. For derivatives designated and that qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in earnings. Cash Flow Hedges of Interest Rate Risk The Company’s objective in using interest rate derivatives is to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps and floors as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. As of December 31, 2020 and 2019, the Company had two interest rate swaps that were designated as cash flow hedges of interest rate risk associated with the Company’s variable-rate subordinated debentures issued by Marquette Capital Trusts III and IV. These swaps had an aggregate notional amount of $51.5 million at both December 31, 2020 and 2019. Interest rate floors designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty if interest rates fall below the strike rate on the contract in exchange for an upfront premium. As of December 31, 2019, the Company had one interest rate floor with a notional amount of $750.0 million that was designated as a cash flow hedge of interest rate risk. On August 28, 2020, the Company terminated this interest rate floor. At the date of termination, the interest rate floor had a net asset fair value of $34.1 million. As of December 31, 2020, the gross unrealized gain on the terminated interest rate floor remaining in AOCI was $17.0 million, or $12.9 million net of tax. The unrealized gain will be reclassified into Interest income as the underlying forecasted transactions impact earnings through the original maturity of the hedged forecasted transactions. The total remaining term over which the unrealized gain will be reclassified into earnings is 3.7 years. For derivatives designated and that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in AOCI and is subsequently reclassified into interest expense and interest income in the period during which the hedged forecasted transaction affects earnings. Amounts reported in AOCI related to interest rate swap derivatives will be reclassified to Interest expense as interest payments are received or paid on the Company’s derivatives. Amounts reported in AOCI related to interest rate floor derivatives will be reclassified to Interest income as interest payments are received or paid on the Company’s derivatives. The Company expects to reclassify $1.3 million from AOCI to Interest expense and $4.7 million from AOCI to Interest income during the next 12 months. As of December 31, 2020, the Company is hedging its exposure to the variability in future cash flows for forecasted transactions over a maximum period of 15.7 years. Non-designated Hedges The remainder of the Company’s derivatives are not designated in qualifying hedging relationships. Derivatives not designated as hedges are not speculative and result from a service the Company provides to certain customers. The Company executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously offset by interest rate swaps 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 swaps associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings.

DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS	19. DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS The following table presents information about the Company’s assets and liabilities measured at fair value on a recurring basis as of December 31, 2020 and 2019 and indicates the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair value. Fair values determined by Level 1 inputs utilize quoted prices in active markets for identical assets and liabilities that the Company has the ability to access. Fair values determined by Level 2 inputs utilize inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets or liabilities in active markets, and inputs other than quoted prices that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. In certain cases, the inputs used to measure fair value may fall into different levels of the hierarchy. In such cases, the fair value is determined based on the lowest level input that is significant to the fair value measurement in its entirety. Assets and liabilities measured at fair value on a recurring basis as of December 31, 2020 and 2019 Fair Value Measurement at December 31, 2020 Using Description December 31, 2020 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets U.S. Treasury $ 651 $ 651 $ — $ — U.S. Agencies 1,568 — 1,568 — Mortgage-backed 4 — 4 — State and political subdivisions 18,545 — 18,545 — Corporates 711 711 — — Trading – other 13,541 13,541 — — Trading securities 35,020 14,903 20,117 — U.S. Treasury 30,740 30,740 — — U.S. Agencies 95,949 — 95,949 — Mortgage-backed 5,468,181 — 5,468,181 — State and political subdivisions 3,623,619 — 3,623,619 — Corporates 81,199 81,199 — — Securities available for sale 9,299,688 111,939 9,187,749 — Equity securities with readily determinable fair values 134,197 134,197 — — Company-owned life insurance 63,575 — 63,575 — Bank-owned life insurance 387,513 — 387,513 — Derivatives 103,554 — 103,554 — Total $ 10,023,547 $ 261,039 $ 9,762,508 $ — Liabilities Derivatives $ 9,375 $ — $ 9,375 $ — Securities sold not yet purchased 2,177 — 2,177 — Total $ 11,552 $ — $ 11,552 $ — Fair Value Measurement at December 31, 2019 Using Description December 31, 2019 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets U.S. Agencies $ 1,246 $ — $ 1,246 $ — Mortgage-backed 392 — 392 — State and political subdivisions 21,764 — 21,764 — Corporates 5,649 5,649 — — Trading – other 16,567 16,567 — — Trading securities 45,618 22,216 23,402 — U.S. Treasury 64,078 64,078 — — U.S. Agencies 93,021 — 93,021 — Mortgage-backed 4,071,794 — 4,071,794 — State and political subdivisions 3,029,917 — 3,029,917 — Corporates 188,552 188,552 — — Securities available for sale 7,447,362 252,630 7,194,732 — Company-owned life insurance 63,900 — 63,900 — Bank-owned life insurance 280,709 — 280,709 — Derivatives 55,276 — 55,276 — Total $ 7,892,865 $ 274,846 $ 7,618,019 $ — Liabilities Derivatives $ 5,997 $ — $ 5,997 $ — Securities sold not yet purchased 14,599 — 14,599 — Total $ 20,596 $ — $ 20,596 $ — Valuation methods for instruments measured at fair value on a recurring basis The following methods and assumptions were used to estimate the fair value of each class of financial instruments measured on a recurring basis: Trading Securities Fair values for trading securities (including financial futures), are based on quoted market prices where available. If quoted market prices are not available, fair values are based on quoted market prices for similar securities. Securities Available for Sale Fair values are based on quoted market prices or dealer quotes, if available. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities. Prices are provided by third-party pricing services and are based on observable market inputs. On an annual basis, the Company compares a sample of these prices to other independent sources for the same securities. Additionally, throughout the year, if securities are sold, comparisons are made between the pricing services prices and the market prices at which the securities were sold. Variances are analyzed, and, if appropriate, additional research is conducted with the third-party pricing services. Based on this research, the pricing services may affirm or revise their quoted price. No significant adjustments have been made to the prices provided by the pricing services. The pricing services also provide documentation on an ongoing basis that includes reference data, inputs and methodology by asset class, which is reviewed to ensure that security placement within the fair value hierarchy is appropriate. Equity securities with readily determinable fair values Fair values are based on quoted market prices. Company-owned Life Insurance Fair value is equal to the cash surrender value of the life insurance policies. Bank-owned Life Insurance Fair value is equal to the cash surrender value of the life insurance policies. Derivatives Fair values are determined using valuation techniques including discounted cash flow analysis on the expected cash flows from each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves, foreign exchange rates, and implied volatilities. The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees. Securities sold not yet purchased Fair values are based on quoted market prices or dealer quotes, if available. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities. Prices are provided by third-party pricing services and are based on observable market inputs. Assets measured at fair value on a non-recurring basis as of December 31, 2020 and 2019 Fair Value Measurement at December 31, 2020 Using Description December 31, 2020 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Gains Recognized During the Twelve Months Ended December 31 Collateral dependent assets $ 35,995 $ — $ — $ 35,995 $ (9,389 ) Other real estate owned 2,798 — — 2,798 (938 ) Total $ 38,793 $ — $ — $ 38,793 $ (10,327 ) Fair Value Measurement at December 31, 2019 Using Description December 31, 2019 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Gains Recognized During the Twelve Months Ended December 31 Impaired loans $ 5,139 $ — $ — $ 5,139 $ 3,973 Other real estate owned 55 — — 55 7 Total $ 5,194 $ — $ — $ 5,194 $ 3,980 Valuation methods for instruments measured at fair value on a non-recurring basis The following methods and assumptions were used to estimate the fair value of each class of financial instruments measured on a non-recurring basis: Collateral Dependent Assets/Impaired loans With the adoption of CECL, collateral dependent assets are assets evaluated as part of the ACL on an individual basis. Those assets for which there is an associated allowance are considered financial assets measured at fair value on a non-recurring basis. Prior to the adoption of CECL, loans identified as impaired were considered financial assets measured at fair value on a non-recurring basis. The valuation method for collateral dependent assets and impaired loans is the same. Adjustments are recorded on certain assets to reflect write-downs that are based on the external appraised value of the underlying collateral. The external appraisals are generally based on recent sales of comparable properties which are then adjusted for the unique characteristics of the property being valued. In the case of non-real estate collateral, reliance is placed on a variety of sources, including external estimates of value and judgments based on the experience and expertise of internal specialists within the Company’s property management group and the Company’s credit department. The valuation of collateral dependent assets and impaired loans are reviewed on a quarterly basis. Because many of these inputs are not observable, the measurements are classified as Level 3. Other real estate owned Other real estate owned consists of loan collateral which has been repossessed through foreclosure. This collateral is comprised of commercial and residential real estate and other non-real estate property, including auto, recreational and marine vehicles. Other real estate owned is recorded as held for sale initially at the fair value of the collateral less estimated selling costs. The initial valuation of the foreclosed property is obtained through an appraisal process similar to the process described in the collateral dependent/impaired loans paragraph above. Subsequent to foreclosure, valuations are reviewed quarterly and updated periodically, and the assets may be marked down further, reflecting a new cost basis. Fair value measurements may be based upon appraisals, third-party price opinions, or internally developed pricing methods and those measurements are classified as Level 3. Fair value disclosures require disclosure of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis or non-recurring basis. The estimated fair value of the Company’s financial instruments at December 31, 2020 and 2019 are as follows (in thousands): Fair Value Measurement at December 31, 2020 Using Carrying Amount Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Estimated Fair Value FINANCIAL ASSETS Cash and short-term investments $ 5,191,015 $ 3,540,680 $ 1,650,335 $ — $ 5,191,015 Securities available for sale 9,299,688 111,939 9,187,749 — 9,299,688 Securities held to maturity (exclusive of allowance for credit losses) 1,014,614 — 1,029,444 — 1,029,444 Trading securities 35,020 14,903 20,117 — 35,020 Other securities 296,053 134,197 161,856 — 296,053 Loans (exclusive of allowance for credit losses) 16,110,359 — 16,413,132 — 16,413,132 Derivatives 103,554 — 103,554 — 103,554 FINANCIAL LIABILITIES Demand and savings deposits 26,175,156 26,175,156 — — 26,175,156 Time deposits 876,095 — 879,841 — 879,841 Other borrowings 2,315,497 65,636 2,249,861 — 2,315,497 Long-term debt 269,595 — 299,858 — 299,858 Derivatives 9,375 — 9,375 — 9,375 OFF-BALANCE SHEET ARRANGEMENTS Commitments to extend credit for loans 6,405 Commercial letters of credit 150 Standby letters of credit 3,365 Fair Value Measurement at December 31, 2019 Using Carrying Amount Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Estimated Fair Value FINANCIAL ASSETS Cash and short-term investments $ 3,276,794 $ 1,701,449 $ 1,575,345 $ — $ 3,276,794 Securities available for sale 7,447,362 252,630 7,194,732 — 7,447,362 Securities held to maturity 1,116,102 — 1,082,345 — 1,082,345 Trading securities 45,618 22,216 23,402 — 45,618 Other securities 108,420 — 108,420 — 108,420 Loans (exclusive of allowance for loan loss) 13,439,525 — 13,601,595 — 13,601,595 Derivatives 55,276 — 55,276 — 55,276 FINANCIAL LIABILITIES Demand and savings deposits 20,376,880 20,376,880 — — 20,376,880 Time deposits 1,226,364 — 1,226,646 — 1,226,646 Other borrowings 1,896,508 31,873 1,864,635 — 1,896,508 Long-term debt 70,372 — 70,713 — 70,713 Derivatives 5,997 — 5,997 — 5,997 OFF-BALANCE SHEET ARRANGEMENTS Commitments to extend credit for loans 5,908 Commercial letters of credit 113 Standby letters of credit 2,966 Cash and short-term investments The carrying amounts of cash and due from banks, federal funds sold and resell agreements are reasonable estimates of their fair values. Securities held to maturity Fair value of held-to-maturity securities are estimated by discounting the future cash flows using current market rates. Other securities Amount consists of FRB and FHLB stock held by the Company, equity securities with readily determinable fair values, and equity securities without readily determinable fair values, including PCM and other equity-method investments and other miscellaneous investments. The carrying amount of the FRB and FHLB stock equals its fair value because the shares can only be redeemed by the FRB and FHLB at their carrying amount. The equity securities with readily determinable fair values are measured at fair value using quoted market prices. For PCM and other equity-method investments, the Company’s proportionate share of the income or loss is recognized on a one-quarter lag based on the valuation of the underlying investment(s). Other equity securities without readily determinable fair values are carried at cost, which approximates fair value. Loans Fair values are estimated for portfolios with similar financial characteristics. Loans are segregated by type, such as commercial, real estate, consumer, and credit card. Each loan category is further segmented into fixed and variable interest rate categories. The fair value of loans are estimated by discounting the future cash flows. The discount rates used are estimated using comparable market rates for similar types of instruments adjusted to be commensurate with the credit risk, overhead costs, and optionality of such instruments. Demand and savings deposits The fair value of demand deposits and savings accounts was the amount payable on demand at December 31, 2020 and 2019. Time deposits The fair value of fixed-maturity certificates of deposit is estimated by discounting the future cash flows using the rates that are currently offered for deposits of similar remaining maturities. Other borrowings The carrying amounts of federal funds purchased, repurchase agreements and other short-term debt are reasonable estimates of their fair value because of the short-term nature of their maturities. Long-term debt Rates currently available to the Company for debt with similar terms and remaining maturities are used to estimate fair value of existing debt. Other off-balance sheet instruments The fair value of loan commitments and letters of credit are determined based on the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreement and the present creditworthiness of the counterparties. Neither the fees earned during the year on these instruments nor their fair value at period-end are significant to the Company’s consolidated financial position.

Nature Of Operations	UMB Financial Corporation is a bank holding company, which offers a wide range of banking and other financial services to its customers through its branches and offices in the states of Missouri, Kansas, Colorado, Illinois, Oklahoma, Texas, Arizona, Nebraska, Iowa, Pennsylvania, South Dakota, Indiana, Utah, Minnesota, California, and Wisconsin. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements. These estimates and assumptions also impact reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Following is a summary of the more significant accounting policies to assist the reader in understanding the financial presentation.
Consolidation	Consolidation The Company and its wholly owned subsidiaries are included in the Consolidated Financial Statements (references hereinafter to the “Company” in these Notes to Consolidated Financial Statements include wholly owned subsidiaries). Intercompany accounts and transactions have been eliminated in consolidation.
Revenue Recognition	Revenue Recognition Interest on loans and securities is recognized based on rate times the principal amount outstanding. This includes the impact of amortization of premiums and discounts. Interest accrual is discontinued when, in the opinion of management, the likelihood of collection becomes doubtful. Other noninterest income is recognized when performance obligations are satisfied.
Cash and cash equivalents	Cash and cash equivalents Cash and cash equivalents include Cash and due from banks and amounts due from the FRB. Cash on hand, cash items in the process of collection, and amounts due from correspondent banks are included in Cash and due from banks. Amounts due from the FRB are interest-bearing for all periods presented and are included in the Interest-bearing due from banks line on the Company’s Consolidated Balance Sheets. This table provides a summary of cash and cash equivalents as presented on the Consolidated Statements of Cash Flows as of December 31, 2020 and 2019 (in thousands) : December 31, 2020 2019 Due from the FRB $ 3,066,928 $ 1,196,212 Cash and due from banks 430,638 472,958 Cash and cash equivalents at end of year $ 3,497,566 $ 1,669,170 Also included in the Interest-bearing due from banks line, but not considered cash and cash equivalents are interest-bearing accounts held at other financial institutions, which totaled $43.1 million and $29.3 million at December 31, 2020 and 2019, respectively.
Loans and Loans Held for Sale	Loans and Loans Held for Sale As further discussed below, the Company adopted ASU 2016-13, “Measurement of Credit Losses on Financial Instruments,” on January 1, 2020. The revised accounting policies are described below. Loans are classified by the portfolio segments of commercial and industrial, specialty lending, commercial real estate, consumer real estate, consumer, credit cards, and leases and other. A loan is considered to be collateral dependent when management believes it is probable that it will be unable to collect all principal and interest due according to the contractual terms of the loan. If a loan is collateral dependent, the Company records a valuation allowance equal to the carrying amount of the loan in excess of the present value of the estimated future cash flows discounted at the loan’s effective rate, based on the loan’s observable market price or the fair value of the collateral. A loan is accounted for as a troubled debt restructuring when a concession had been granted to a debtor experiencing financial difficulties. The Company’s modifications generally include interest rate adjustments, and amortization and maturity date extensions. These modifications allow the debtor short-term cash relief to allow them to improve their financial condition. Restructured loans are considered to be collateral dependent and are individually evaluated for credit loss as part of the allowance for credit loss analysis. Loans, including those that are considered to be collateral dependent or a troubled debt restructuring, are evaluated regularly by management. Loans are considered delinquent when payment has not been received within 30 days of its contractual due date. The adequacy of the ACL on loans is based on management’s judgment and continuous evaluation of the pertinent factors underlying the credit quality inherent in the loan portfolio. Consideration of quantitative and qualitative factors relevant to each specific segmentation of loans includes lifetime historical loss experience, the impact of the current economic environment, reasonable and supportable forecasts, and detailed analysis of loans determined to be collateral dependent. The actual losses incurred over the lifetime of the portfolio, notwithstanding such considerations, however, could differ from the amounts estimated by management. The Company maintains an allowance for off-balance sheet credit exposures, to address the credit risk to which the Company is exposed via a contractual obligation to extend credit, unless that obligation is unconditionally cancelable by the Company. The allowance for off-balance sheet credit exposure is included in the Accrued expenses and taxes line item in the Consolidated Balance Sheets. In order to maintain the allowance for off-balance sheet items at an appropriate level, a provision to increase or reduce the allowance is included in the Company’s Consolidated Statements of Income. The allowance for off-balance sheet credit exposure is calculated by applying portfolio segment expected credit loss rates to the expected amount to be funded. Loans held for sale are carried at the lower of aggregate cost or market value. Loan fees (net of certain direct loan origination costs) on loans held for sale are deferred until the related loans are sold or repaid. Gains or losses on loan sales are recognized at the time of sale and determined using the specific identification method. Prior to the adoption of ASU 2016-13, loans were classified by the portfolio segments of commercial, real estate, consumer, and leases. The portfolio segments were further disaggregated into loan classes of commercial, asset-based, factoring, commercial credit card, real estate – construction, real estate – commercial, real estate – residential, real estate – HELOC, consumer – credit card, consumer – other, and leases. A loan was considered to be impaired when management believed it was probable that it would be unable to collect all principal and interest due according to the contractual terms of the loan. Additionally, the adequacy of the allowance for loan losses was based on management’s evaluation of the inherent losses that had been incurred within the existing portfolio of loans. Further, a reserve to address the risk of loss associated with loan contingencies was separately maintained. This reserve was assessed by dividing the contingencies into pools of similar loan commitments and applying to factors to each pool. The gross amount of contingent exposure was first multiplied by a potential factor to estimate the degree to which the unused commitments might reasonably be expected to be used in a time of high usage. The resultant figure was then multiplied by a factor to estimate the risk of loss assuming funding of these loans. The potential loss estimates for each segment of the portfolio were added to arrive at a total potential loss estimate that was used to set the reserve.
Securities	Securities Debt securities available for sale principally include U.S. Treasury and agency securities, GSE mortgage-backed securities, certain securities of state and political subdivisions, and corporates. Debt securities classified as available for sale are measured at fair value. Unrealized holding gains and losses are excluded from earnings and reported in Accumulated other comprehensive income (AOCI) until realized. Securities held to maturity are carried at amortized historical cost , net of the allowance for credit losses, based on management’s intention, and the Company’s ability to hold them to maturity. The Company classifies certain securities of state and political subdivisions as held to maturity. Trading securities, acquired for subsequent sale to customers, are carried at fair value. Market adjustments, fees and gains or losses on the sale of trading securities are considered to be a normal part of operations and are included in trading and investment banking income.
Equity-method investments	Equity-method investments The Company accounts for certain other investments using equity-method accounting. For equity securities without readily determinable fair values, the Company’s proportionate share of the income or loss is recognized on a one-quarter lag. When transparency in pricing exists, other investments are considered equity securities with readily determinable fair values.
Goodwill and Other Intangibles	Goodwill and Other Intangibles Goodwill is tested for impairment annually and more frequently whenever events or changes in circumstances indicate that it is more likely than not that the fair value of a reporting unit is less than its carrying value. To test goodwill for impairment, the Company performs a qualitative assessment of each reporting unit. If the Company determines, on the basis of qualitative factors, that the fair value of the reporting unit is more likely than not greater than the carrying amount, the quantitative impairment test is not required. Otherwise, the Company compares the fair value of its reporting units to their carrying amounts to determine if an impairment exists and the amount of impairment loss. An impairment loss is measured as the excess of the carrying value of a reporting unit’s goodwill over its fair value. No goodwill impairments were recognized in 2020, 2019, or 2018. Other intangible assets, which relate to core deposits, non-compete agreements, and customer relationships, are amortized over their useful life. Intangible assets are evaluated for impairment when events or circumstances dictate. No intangible asset impairments were recognized in 2020, 2019, or 2018. The Company does not have any indefinite lived intangible assets.
Premises and Equipment	Premises and Equipment Premises and equipment are stated at cost less accumulated depreciation, which is computed primarily on the straight line method. Premises are depreciated over 15 to 40 year lives, while equipment is depreciated over lives of 3 to 20 years. Gains and losses from the sale of Premises and equipment are included in Other noninterest income and Other noninterest expense, respectively.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets Long-lived assets, including Premises and equipment, are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset or group of assets may not be recoverable. The impairment review includes a comparison of future cash flows expected to be generated by the asset or group of assets to their current carrying value. If the carrying value of the asset or group of assets exceeds expected cash flows (undiscounted and without interest charges), an impairment loss is recognized to the extent the carrying value exceeds fair value. No impairments were recognized in 2020, 2019, or 2018.
Income Taxes	Income Taxes The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are measured based on the differences between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the periods in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. The provision for deferred income taxes represents the change in the deferred income tax accounts during the year excluding the tax effect of the change in net unrealized gain (loss) on securities available for sale. The Company records deferred tax assets to the extent these assets will more likely than not be realized. All available evidence is considered in making such determination, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and recent financial operations. A valuation allowance is recorded for the portion of deferred tax assets that are not more-likely-than-not to be realized , and any changes to the valuation allowance are recorded in income tax expense. The Company records the financial statement effects of an income tax position when it is more likely than not, based on the technical merits, that it will be sustained upon examination. A tax position that meets the more-likely-than-not recognition threshold is measured and recorded as the largest amount of tax benefit that is greater than 50 percent likely of being realized upon ultimate settlement with a taxing authority. Previously recognized tax positions are derecognized in the first period in which it is no longer more likely than not that the tax position will be sustained. The benefit associated with previously unrecognized tax positions are generally recognized in the first period in which the more-likely-than-not threshold is met at the reporting date, the tax matter is ultimately settled through negotiation or litigation, or when the related statute of limitations for the relevant taxing authority to examine and challenge the tax position has expired. The recognition, derecognition and measurement of tax positions are based on management’s best judgment given the facts, circumstances and information available at the reporting date. The Company recognizes accrued interest related to unrecognized tax benefits in interest expense and penalties in other noninterest expense. Accrued interest and penalties are included within the related liability lines in the Consolidated Balance Sheets. For the year ended December 31, 2020, the Company has recognized an immaterial amount in interest and penalties related to the unrecognized tax benefits.
Derivatives	Derivatives The Company records all derivatives on the Consolidated Balance Sheets at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Currently, three of the Company’s derivatives are designated in qualifying hedging relationships. The remainder of the Company’s derivatives are not designated in qualifying hedging relationships, as the derivatives are not used to manage risks within the Company’s assets or liabilities. All changes in fair value of the Company’s non-designated derivatives and fair value hedges are recognized directly in earnings. Changes in fair value of the Company’s cash flow hedges are recognized in AOCI and are reclassified to earnings when the hedged transaction affects earnings.
Per Share Data	Per Share Data Basic income per share is computed based on the weighted average number of shares of common stock outstanding during each period. Diluted year-to-date income per share includes the dilutive effect of 205,959, 310,614, and 435,800 shares issuable upon the exercise of stock options, nonvested restricted shares, and nonvested restricted stock units, granted by the Company that were outstanding at December 31, 2020, 2019, and 2018, respectively. Certain options, restricted stock and restricted stock units issued under employee benefit plans were excluded from the computation of diluted earnings per share because they were anti-dilutive. Outstanding options, restricted stock and restricted stock units of 198,671, 114,130, and 125,765 for the years ended December 31, 2020, 2019, and 2018, respectively, were excluded from the computation of diluted income per share because their inclusion would have been anti-dilutive.
Accounting for Stock-Based Compensation	Accounting for Stock-Based Compensation The Company measures the cost of employee services received in exchange for an award of equity instruments based on the fair value of the award on the date of the grant. For stock options, restricted stock, and service-based restricted stock unit awards, the grant date fair value is estimated using either an option-pricing model which is consistent with the terms of the award or an observed market price, if such a price exists. For performance-based restricted stock unit awards, the grant date fair value is based on the quoted price of the Company’s common stock on the grant date less the present value of expected dividends not received during the vesting period. Such cost is generally recognized over the vesting period during which an employee is required to provide service in exchange for the award and, in some cases, when performance metrics are met. The Company accounts f or forfeitures of stock-based compensation on an actual basis as they occur .
