NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 1 – NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations Equity Bank is a Kansas state-chartered bank and member of the Federal Reserve (state Fed member bank jointly supervised by both the Federal Reserve Bank of Kansas City and the Office of the Kansas State Bank Commissioner). The Company is primarily engaged in providing a full range of banking, mortgage banking and financial services to individual and corporate customers generally in Arkansas, Kansas, Missouri and Oklahoma. Equity Bank competes with a variety of other financial institutions including large regional banks, community banks and thrifts as well as credit unions and other non-traditional lenders. Use of Estimates Cash Equivalents Securities Interest income includes amortization of purchase premium or discount. Premiums and discounts on securities are amortized on the level-yield basis without anticipating prepayments, except for certain securities where prepayments are anticipated. Gains and losses on sales are recorded on the trade date and determined using the specific identification method. Management evaluates securities for other-than-temporary impairment (“OTTI”) on at least a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. For securities in an unrealized loss position, management considers the extent and duration of the unrealized loss and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or it is more likely than not that it will be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: 1) OTTI related to credit loss, which must be recognized in the income statement and 2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. All OTTI related to equity securities is recognized through earnings. Equity investments with a readily determinable fair value are measured at fair value with changes in fair value recognized in net income. The exit price concept is used when measuring the fair value of financial instruments for disclosure purposes. Loans Held for Sale Loans Purchased Credit Impaired Loans. As a part of acquisitions, the Company acquired certain loans, for which there was, at acquisition, evidence of deterioration of credit quality since origination. These purchased credit impaired loans were recorded at the acquisition date fair value, such that there is no carryover of the seller’s allowance for loan losses. After acquisition, losses are recognized by an increase in the allowance for loan losses. Such purchase credit impaired loans are accounted for individually. The Company estimates the amount and timing of expected cash flows for each loan, and the expected cash flows in excess of the amount paid are recorded as interest income over the remaining life of the loan (accretable yield). During acquisitions, if the Company expects to liquidate the loan collateral in a relatively short period of time, the Company will assign no value to accretable yield as the impact is immaterial. The excess of the loan’s contractual principal and interest over expected cash flows is not recorded (non-accretable difference). Over the life of the loan, expected cash flows continue to be estimated. If the present value of the expected cash flows is less than the carrying amount, a loss is recorded. If the present value of the expected cash flows is greater than the carrying amount, it is recognized as part of future interest income. Nonaccrual Loans. Generally, loans are designated as nonaccrual when either principal or interest payments are 90 days or more past due based on contractual terms unless the loan is well secured and in the process of collection. Consumer loans are typically charged-off no later than 180 days past due. In all cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. When a loan is placed on nonaccrual status, unpaid interest credited to income is reversed against income. Future interest income may be recorded on a cash basis after recovery of principal is reasonably assured. Nonaccrual loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Impaired Loans. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all contractual principal and interest due according to the terms of the loan agreement. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate or on the value of the underlying collateral if the loan is collateral dependent. The Company evaluates the collectability of both principal and interest when assessing the need for a loss accrual. Factors considered by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. Troubled Debt Restructurings . In cases where a borrower experiences financial difficulties and the Company makes certain concessionary modifications to contractual terms, the loan is classified as a troubled debt restructured loan and classified as impaired. Generally, a nonaccrual loan that is a troubled debt restructuring remains on nonaccrual until such time that repayment of the remaining principal and interest is not in doubt and the borrower has a period of satisfactory repayment performance. Allowance for Loan Losses The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. If a loan is impaired, a portion of the allowance is allocated so that the loan is reported net at the present value of estimated future cash flows using the loan’s existing rate or at the fair value of collateral if repayment is expected solely from the sale of the collateral. Troubled debt restructurings are separately identified for impairment disclosures and are measured at the present value of estimated future cash flows using the loan’s effective rate at inception. If a troubled debt restructuring is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of the collateral. For troubled debt restructurings that subsequently default, the Company determines the amount of reserve in accordance with the accounting policy for the allowance for loan losses. The general component of the allowance for loan losses covers non-impaired loans and is based on historical loss experience adjusted for current factors. The historical loss experience is determined by portfolio and class and is based on the actual loss history experienced by the Company. This actual loss experience is then adjusted by comparing current conditions to the conditions that existed during the loss history. The Company considers the changes related to (i) lending policies, (ii) economic conditions, (iii) nature and volume of the loan portfolio and class, (iv) lending staff, (v) volume and severity of past due, non-accrual and risk graded loans, (vi) loan review system, (vii) value of underlying collateral for collateral dependent loans, (viii) concentration levels and (ix) effects of other external factors. The Company considers loan performance and collateral values in assessing risk for each class in the loan portfolio, as follows: • Commercial and industrial loans are dependent on the strength of the industries of the related borrowers and the success of their businesses. Commercial and industrial loans are advanced for equipment purchases, to provide working capital or meet other financing needs of the business. These loans may be secured by accounts receivable, inventory, equipment or other business assets. Financial information is obtained from the borrower to evaluate the debt service coverage and ability to repay the loans. • Commercial real estate loans are dependent on the industries tied to these loans, as well as the local commercial real estate market. The loans are secured by real estate and typically appraisals are obtained to support the loan amount. Generally, an evaluation of the project’s cash flows is performed to evaluate the borrower’s ability to repay the loan at the time of origination and periodically updated during the life of the loan. • Residential real estate loans are affected by the local residential real estate market, the local economy and movement in interest rates. The Company evaluates the borrower’s repayment ability through a review of credit reports and debt to income ratios. Generally, appraisals are obtained to support the loan amount. • Agricultural real estate loans are real estate loans related to farmland and are affected by the value of farmland. Generally, the Company evaluates the borrower’s ability to repay based on cash flows from farming operations. • Consumer loans are dependent on the local economy. Consumer loans are generally secured by consumer assets, but may be unsecured. Typically, the Company evaluates the borrower’s repayment ability through a review of credit scores and an evaluation of debt to income ratios. • Agricultural loans are primary operating lines subject to annual farming revenues, including productivity and yield of the farm products and market pricing at the time of sale. There have been no material changes to the Company’s accounting policies related to its allowance for loan loss methodology during 2019 and 2018. Transfers of Financial Assets Bank-Owned Life Insurance Other Real Estate Owned Premises and Equipment Premises and equipment and other long-term assets are reviewed for impairment when events indicate their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value. Lease Obligation. The Company evaluates contracts that convey the right to control the use of identified property, plant or equipment for a period of time for consideration to determine if they are lease obligations. The Company evaluates each lease component to determine if the lease qualifies as a financing lease or as an operating lease. Leases that meet any of the following criteria are considered financing leases: (1) the lease transfers ownership of the underlying asset by the end of the lease term; (2) the lease grants the Company an option to purchase the underlying asset that the Company is reasonably certain to exercise; (3) the lease term is the major part of the remaining economic life of the underlying asset; (4) the present value of the sum of the lease payments and any residual value guaranteed by the Company that is not already reflected in lease payments equals or exceeds substantially all of the fair of the underlying asset; or (5) the underlying asset is of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term. If none of the financing lease criteria are met, the lease is considered an operating lease. The Company evaluates each lease to determine the lease term which will be used based on the type and use of the leased equipment and future expected changes in operations. The resulting lease term will consist of the non-cancellable period for which the Company has the right to use the underlying asset plus (1) periods covered by an option to extend the lease if the Company is reasonably certain to exercise that option; (2) periods covered by an option to terminate the lease if the Company is reasonably certain not to exercise that option; and (3) periods covered by an option to extend the lease in which exercise of the option is controlled by the lessor. The Company has certain leases that contain options to extend the lease and contain options for changes in lease payments which are evaluated by the Company to determine the recorded values for right-of-use assets and lease liability. Lease payments that are contractually known at lease inception are used by the Company for calculating the right-of-use asset and lease liability. Lease payments that vary because of facts or circumstances after the commencement date of the lease from other than passage of time are treated as variable lease payments and are recorded to lease expense in the period in which the obligation for the payments are incurred by the Company. Variable lease payments are not part of the lease payments for determining the right-of-use asset or the lease liability at the lease commencement date. The discount rate to initially determine the present value of the lease payments is based on the information available at the lease commencement date and is either the rate implicit in the lease or the Company’s incremental borrowing rate If the rate implicit in the lease is known or determinable, that rate shall be used. If that rate is not known, the Company’s incremental borrowing rate shall be used. At the January 2019, implementation of this accounting guidance, the Company’s incremental borrowing rate based on the remaining lease term was used to calculate the right-of-use assets and operating lease liabilities. Operating lease right-of-use assets and lease obligations are accounted for subsequent to initial recording by amortizing the right-of-use asset over the lease term on a straight-line method while the lease obligation is increased by the accrual of interest and decreased by subsequent lease payments. Operating lease right-of-use asset amortization and lease obligation interest are reported in non-interest expense in the Consolidated Statements of Operations. Operating lease payments and variable lease payments are reflected within cash flows from operating activities in the Consolidated Statement of Cash Flows. Financing lease right-of-use assets and lease obligations are accounted for subsequent to initial recording by amortizing the right-of-use asset similar to owned assets over the lesser of the lease term or economic life of the asset if the lease transfers ownership of the leased asset while the lease obligation is increased by the accrual of interest and decreased by subsequent lease payments. Financing lease right-of-use asset amortization is reported in non-interest expense, similar to other owned assets, and lease obligation interest accruals are reported in interest expense in the Consolidated Statements of Operations. Financing lease obligation principal payments are reflected within cash flows from financing activities and interest payments and variable lease payments are reflected with the cash flows from operating activities in the Consolidated Statements of Cash Flows. The Company evaluates lease modifications and will consider the modification a new contract if the modification grants the lessee an additional right of use not included in the original lease and the lease payments increase commensurate with the stand-alone price for the additional right-of-use asset. The Company will reallocate the remaining consideration in the contract and remeasure the lease liability using a discount rate for the lease determined at the effective date of the lease modification if the contract modification does any of the following: (1) grants the Company an additional right of use that was not included in the original contract; (2) extends or reduces the term of an existing lease; (3) fully or partially terminates an existing lease; or (4) changes the consideration in the contract only. The Company will recognize the remeasurement of the lease liability for the modification as an adjustment of the right-of-use asset when the contract modification grants additional right-of-use-assets, extends or reduces the term of the lease or changes the consideration of the lease contract. In the case of full or partial termination of the lease, the Company will decrease the carrying amount of the right-of-use-asset on a proportionate basis to the reduction in the lease liability with a gain or loss recognized for the difference between the lease liability adjustment and right of use asset adjustment. If the Company modifies an operating lease which it is the lessor and the modification is not accounted for as a separate contract, the Company will account for the modification as if it were a termination of the existing lease and the creation of a new lease that commences on the effective date of the modification as follows: • If the modified lease is classified as an operating lease, the Company will consider any prepaid or accrued lease rentals relating to the original lease as part of the lease payments for the modified lease. • If the modified lease is classified as a direct financing lease or a sales-type lease, the Company will derecognize any deferred rent liability or accrued rent asset and adjust the selling profit or loss. If the Company modifies a direct financing lease which it is the lessor and the modification is not accounted for as a separate contract, the Company will account for the modified lease as follows: • If the modified lease is classified as a direct financing lease, the Company will adjust the discount rate for the modified lease, so the initial net investment equals the carrying amount of the original lease at the modification effective date. • If the modified lease is classified as a sales-type lease, the Company shall determine the selling profit/loss on commencement date of the modified lease as the difference between the fair value of the underlying asset and net investment in the original lease prior to modification. • If the modified lease is classified as an operating lease, the carrying amount of the underlying asset shall equal the net investment in the original lease immediately before the effective date of the modification. If the Company modifies a sales-type lease which it is the lessor and the modification is not accounted for as a separate contract, the Company will account for the modified lease as follows: • If the modified lease is classified as a direct financing lease, the Company will adjust the discount rate for the modified lease, so the initial net investment of the modified lease equals the carrying amount of the original lease at the modification effective date. • If the modified lease is classified as a direct financing lease, the Company will adjust the discount rate for the modified lease, so the initial net investment equals the carrying amount of the original lease at the modification effective date. Federal Reserve Bank and Federal Home Loan Bank Stock Goodwill and Core Deposit Intangibles Credit Related Financial Instruments Derivatives An interest rate swap is an agreement between two entities to exchange cash flows in the future. The agreement sets the dates on which the cash flows will be paid and the manner in which the cash flows will be calculated. Typically, an interest rate swap transaction is used as an exchange of cash flows based on a fixed rate for cash flows based on a variable rate. In an interest rate cap agreement, a cash flow is generated if the price or interest rate of an underlying variable rises above a certain threshold price or interest rate. In an interest rate floor agreement, a cash flow is generated if the price or interest rate of an underlying variable falls below a certain threshold price or interest rate. Caps and floors are designed as protection against the interest rate on a variable rate asset or liability rising above or falling below a certain level. At the inception of a derivative contract, the Company designates the derivatives as one of three types based on the Company’s intentions and belief as to likely effectiveness as a hedge. These three types are: (1) a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (“fair value hedge”); (2) a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (“cash flow hedge”); or (3) an instrument with no hedging designation (“stand-alone derivative”). For a fair value hedge, the gain or loss on the derivative, as well as the offsetting loss or gain on the hedged item, are recognized in current earnings as fair value changes. For a cash flow hedge, the gain or loss on the derivative is reported in other comprehensive income and is reclassified into earnings in the same periods during which the hedged transaction affects earnings. For both types of hedges, changes in the fair value of derivatives that are not highly effective in hedging the changes in fair value or expected cash flows of the hedged item are recognized immediately in current earnings. Changes in the fair value of derivatives that do not qualify for hedge accounting are reported currently in earnings as non-interest income. Net cash settlements on derivatives that qualify for hedge accounting are recorded in interest income or interest expense, based on the item being hedged. Net cash settlements on derivatives that do not qualify for hedge accounting are reported in non-interest income. Cash flows on hedges are classified in the cash flow statement the same as the cash flows of the items being hedged unless the derivative meets the criteria to be a financing derivative. All derivatives are recognized in the consolidated balance sheet at their fair values and are reported as either derivative assets or derivative liabilities net of accrued net settlements and collateral, if any. The individual derivative amounts are netted by counterparty when the netting requirements have been met. If these netted values are positive, they are classified as an asset and, if negative, they are classified as a liability. The Company formally documents the relationship between derivatives and hedged items, as well as the risk-management objective and the strategy for undertaking hedge transactions at the inception of the hedging relationship. This documentation includes linking fair value or cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, at least quarterly, whether the derivative instruments that are used are highly effective in offsetting changes in fair values or cash flows of the hedged items. The Company discontinues hedge accounting when it determines that the derivative is no longer effective in offsetting changes in the fair value or cash flows of the hedged item, the derivative is settled or terminates, a hedged forecasted transaction is no longer probable, a hedged firm commitment is no longer firm or treatment of the derivative as a hedge is no longer appropriate or intended. When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded as non-interest income. When a fair value hedge is discontinued, the hedged asset or liability is no longer adjusted for changes in fair value and the existing basis adjustment is amortized or accreted over the remaining life of the asset or liability. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transactions are still expected to occur, gains or losses that are accumulated in other comprehensive income are amortized into earnings over the same periods which the hedged transactions will affect earnings. The Company has entered into interest rate cap derivatives to assist with interest rate risk management. These derivatives are not designated as hedging instruments but rather as stand-alone derivatives. The fair values of stand-alone derivatives are included in other assets and other liabilities. Changes in fair value of stand-alone derivatives are recorded through earnings as non-interest income. Income Taxes On December 22, 2017, the President of the United States signed the 2017 Tax Cuts and Jobs Act (Tax Reform) which reduced the U.S. federal statutory corporate income tax rate from 35% to 21% beginning in 2018. In connection with the December 2017, enactment the Company recognized a $1,086 re-measurement of its net deferred tax assets, including a re-measurement of $535 in a net deferred tax asset related to unrealized losses on available-for-sale securities and held-to-maturity securities previously transferred from available-for-sale. Because the tax effect of variations in unrealized losses on available-for-sale securities and transferred held-to-maturity securities impact accumulated other comprehensive income, the Company had a stranded tax effect of $535 as of the date of enactment. The Company elected to early adopt ASU 2018-02 resulting in a reclassification of $535 from accumulated other comprehensive income to retained earnings in December 2017. The Company recognizes interest and/or penalties related to income tax matters in income tax expense. There were no such interest or penalties incurred in 2019, 2018 or 2017. Earnings Per Common Share Share-Based Payments Compensation expense associated with restricted stock units is based on the fair value of the units at the grant date.

Business Combinations [Abstract]
BUSINESS COMBINATIONS	On February 8, 2019, the Company acquired the assets and assumed the deposits and certain other liabilities of two bank locations in Guymon, Oklahoma and one bank location in Cordell, Oklahoma, from MidFirst Bank, based in Oklahoma City, Oklahoma (“MidFirst”). Results of operations of these new banks were included in the Company’s results of operations beginning February 9, 2019. Acquisition-related costs associated with this acquisition were $902 ($684 on an after-tax basis) and are included in merger expense in the Company’s income statement for the year ended December 31, 2019. The fair value of consideration exchanged exceeded the recognized amounts of the identifiable net assets and resulted in goodwill of $4,720. Goodwill resulted from a combination of expected synergies including expansion into western Oklahoma with an additional three bank locations and growth opportunities. The following table summarizes the consideration paid for the MidFirst assets acquired and liabilities assumed recognized at the acquisition date. Recognized amounts of identifiable assets acquired and liabilities assumed: Cash and due from banks $ 85,360 Loans 6,507 Premises and equipment 656 Core deposit intangible 1,350 Other assets 13 Total assets acquired 93,886 Deposits 98,543 Interest payable and other liabilities 63 Total liabilities assumed 98,606 Total identifiable net assets (4,720 ) Goodwill 4,720 $ — The fair value of net assets acquired includes fair value adjustments to certain loans that were not considered impaired as of the acquisition date. The fair value adjustments were determined using discounted contractual cash flows. However, the Company believes that all contractual cash flows related to these financial instruments will be collected. As such, these loans were not considered impaired at the acquisition date and were not subject to the guidance relating to purchased credit impaired loans, which have shown evidence of credit deterioration since origination. The following table presents information about the loans acquired in the MidFirst acquisition as of the date of acquisition. Non-Credit Impaired Purchased Impaired Contractually required principal $ 6,770 $ — Non-accretable difference (expected losses) — — Cash flows expected to be collected 6,770 — Accretable yield (263 ) — Fair value of acquired loans $ 6,507 $ — The following table presents the carrying value of the loans acquired in the MidFirst acquisition by class, as of the date of acquisition. Non-Credit Impaired Purchased Credit Impaired Total Commercial real estate $ 668 $ — $ 668 Commercial and industrial 34 — 34 Residential real estate 3,271 — 3,271 Consumer 2,534 — 2,534 Fair value of acquired loans $ 6,507 $ — $ 6,507 Assuming that the MidFirst acquisition would have taken place on January 1, 2018, total combined revenue would have been $200,807 for year ended December 31, 2019 and $183,022 for year ended December 31, 2018. Net income would have been $25,216 and $33,856 at December 31, 2019 and 2018. The pro forma amounts disclosed exclude merger expense from non-interest expense, which is considered a material non-recurring adjustment. Separate revenue and earnings of the former MidFirst locations are not available subsequent to the acquisition. On August 23, 2018, the Company acquired City Bank and Trust Company (“City Bank”), which had one branch location in Guymon, Oklahoma, from Docking Bancshares, Inc. Results of operations of City Bank were included in the Company’s results of operations beginning August 24, 2018. Acquisition-related costs associated with this merger were $1,387 ($1,054 on an after-tax basis) and are included in merger expenses in the Company’s income statement for the year ended December 31, 2018. The fair value of consideration exchanged exceeded the recognized amounts of the identifiable net assets and resulted in goodwill of $5,824. Goodwill resulted from a combination of expected synergies, expansion in western Oklahoma with the addition of one branch location and growth opportunities. The following table summarizes the consideration paid for City Bank and the amounts of the assets acquired and liabilities assumed recognized at the merger date. Fair value of consideration: Cash $ 18,900 $ 18,900 Recognized amounts of identifiable assets acquired and liabilities assumed: Cash and due from banks $ 27,659 Held-to-maturity securities 44,927 Federal Reserve Bank and Federal Home Loan Bank stock 881 Loans 77,148 Premises and equipment 2,044 Core deposit intangibles 3,360 Other real estate owned 307 Other assets 1,103 Total assets acquired 157,429 Deposits 126,853 Federal Home Loan Bank advances 17,353 Interest payable and other liabilities 147 Total liabilities assumed 144,353 Total identifiable net assets 13,076 Goodwill 5,824 $ 18,900 The fair value of net assets acquired includes fair value adjustments to certain loans that were not considered purchased credit impaired as of the merger date. The fair value adjustments were determined using discounted contractual cash flows. However, the Company believes that all contractual cash flows related to these financial instruments will be collected. As such, these loans were not considered impaired at the merger date and were not subject to the guidance relating to purchased credit impaired loans, which have shown evidence of credit deterioration since origination. Cash flows associated with purchased credit impaired loans are not considered reasonably predictable and as such these loans are considered nonaccrual. The following table presents the best available information about the loans acquired in the City Bank merger as of the date of merger. Non-Credit Impaired Purchased Impaired Contractually required principal $ 74,918 $ 5,136 Non-accretable difference (expected losses) — (1,156 ) Cash flows expected to be collected 74,918 3,980 Accretable yield (1,750 ) — Fair value of acquired loans $ 73,168 $ 3,980 The following table presents the carrying value of the loans acquired in the City Bank merger by class, as of the date of merger.

Results of operations of KBC were included in the Company’s results of operations beginning May 5, 2018. Acquisition-related costs associated with this merger were $4,360 ($3,349 on an after-tax basis) for year ended December 31, 2018, and $14 ($9 on an after-tax basis) for year ended December 31, 2017 and are included in merger expenses in the Company’s income statements. The fair value of consideration exchanged exceeded the recognized amounts of the identifiable net assets and resulted in goodwill of $14,010. Goodwill resulted from a combination of expected synergies, expansion in southwest Kansas with the addition of five branch locations, growth opportunities and increases in stock prices after the stock exchange ratios were negotiated. The following table summarizes the consideration paid for KBC and the amounts of the assets acquired and liabilities assumed recognized at the merger date. Fair value of consideration: Common Stock $ 32,103 Cash 14,918 $ 47,021 Recognized amounts of identifiable assets acquired and liabilities assumed: Cash and due from banks $ 27,899 Available-for-sale securities 22,820 Held-to-maturity securities 92,028 Federal Reserve Bank and Federal Home Loan Bank stock 475 Loans 159,359 Premises and equipment 5,835 Core deposit intangibles 8,080 Other assets 5,618 Total assets acquired 322,114 Deposits 288,352 Interest payable and other liabilities 751 Total liabilities assumed 289,103 Total identifiable net assets 33,011 Goodwill 14,010 $ 47,021 The fair value of net assets acquired includes fair value adjustments to certain loans that were not considered purchased credit impaired as of the merger date.

(“Adams”), based in Blue Springs, Missouri. Results of operations of Adams were included in the Company’s results of operations beginning May 5, 2018. Acquisition-related costs associated with this merger were $1,217 ($961 on an after-tax basis) for year ended December 31, 2018, and $4 ($2 on an after-tax basis) for year ended December 31, 2017, are included in merger expenses in the Company’s income statements. The fair value of consideration exchanged exceeded the recognized amounts of the identifiable net assets and resulted in goodwill of $8,465. Goodwill resulted from a combination of expected synergies, expansion in the Kansas City metro area with the addition of one branch location, growth opportunities and increases in stock prices after the stock exchange ratios were negotiated. The following table summarizes the consideration paid for Adams and the amounts of the assets acquired and liabilities assumed recognized at the merger date.

The tables above present unrealized losses on held-to-maturity securities since the date of their purchase, independent of the impact associated with changes in cost basis upon transfer from the available-for-sale designation to the held-to-maturity designation. Unrealized losses on securities have not been recognized into income because the security issuers are of high credit quality, management does not intend to sell and it is more likely than not that the Company will not be required to sell the securities prior to their anticipated recovery, and the decline in fair value is largely due to changes in interest rates. The fair value is expected to recover as the securities approach maturity. The proceeds from sales and the associated gains and losses on available-for-sale securities reclassified from other comprehensive income to income are listed below. 2019 2018 2017 Proceeds $ — $ — $ 84,087 Gross gains — — 271 Gross losses — — — Income tax expense on net realized gains — — 103

The Company analyzes loans individually by classifying the loans as to credit risk. Consumer loans are considered unclassified credits unless downgraded due to payment status or reviewed as part of a larger credit relationship. The Company uses the following definitions for risk ratings: Pass : Loans classified as pass do not have any noted weaknesses and repayment of the loan is expected. These loans are considered unclassified. Special Mention : Loans classified as special mention have 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 loan or of the Company’s credit position at some future date. These loans are considered classified. Substandard : Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. These loans are considered classified. Doubtful : Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. These loans are considered classified. The risk category of loans by class of loans is as follows as of December 31, 2019 and 2018. December 31, 2019 Unclassified Classified Total Commercial real estate $ 1,146,696 $ 11,326 $ 1,158,022 Commercial and industrial 560,282 31,770 592,052 Residential real estate 495,418 8,021 503,439 Agricultural real estate 132,065 9,803 141,868 Consumer 67,997 381 68,378 Agricultural 88,607 4,286 92,893 Total $ 2,491,065 $ 65,587 $ 2,556,652 December 31, 2018 Unclassified Classified Total Commercial real estate $ 1,215,015 $ 36,977 $ 1,251,992 Commercial and industrial 553,045 29,482 582,527 Residential real estate 439,184 5,356 444,540 Agricultural real estate 129,285 10,047 139,332 Consumer 61,976 918 62,894 Agricultural 90,848 3,275 94,123 Total $ 2,489,353 $ 86,055 2,575,408 Purchased Credit Impaired Loans The Company has acquired loans, for which there was, at acquisition, evidence of deterioration of credit quality since origination and it was probable, at acquisition, that all contractually required payments would not be collected. The recorded investments in purchased credit impaired loans as of December 31, 2019, 2018 and 2017 were as follows. 2019 2018 2017 Contractually required principal payments $ 29,895 $ 40,772 $ 41,349 Discount (6,505 ) (10,077 ) (12,492 ) Recorded investment $ 23,390 $ 30,695 $ 28,857 The accretable yield associated with these loans was $3,127, $3,785 and $1,980 as of December 31, 2019, 2018 and 2017. The interest income recognized on these loans was $2,227, $1,096 and $1,785 for the years ended December 31, 2019, 2018 and 2017. For the year ended December 31, 2019 there was $628 reversal of provision for loan losses recorded for these loans. For the years ended December 31, 2018 and 2017 there was $714 and $194 provision for loan losses recorded for these loans. Troubled Debt Restructurings Consistent with accounting and regulatory guidance, the Company recognizes a TDR when the Company, for economic or legal reasons related to a borrower’s financial difficulties, grants a concession to the borrower that would not normally be considered. Regardless of the form of concession granted, the Company’s objective in offering a TDR is to increase the probability of repayment of the borrower’s loan. Troubled debt restructurings by class of loans are as follows as of December 31, 2019. Number of Loans Recorded Investment Impairment Recognized Commercial real estate 1 $ 1,247 $ — Commercial and industrial 1 14,261 4,994 Total troubled debt restructurings 2 $ 15,508 $ 4,994 Consistent with accounting and regulatory guidance, the Company recognizes a TDR when the Company, for economic or legal reasons related to a borrower’s financial difficulties, grants a concession to the borrower that would not normally be considered. Regardless of the form of concession granted, the Company’s objective in offering a TDR is to increase the probability of repayment of the borrower’s loan. A concession was granted on these loans in the form of either an interest rate reduction, material maturity date extension or an extension of the amortization plan to provide payment relief. These loans are included in the previous impaired loan tables, were individually assessed for impairment and a charge-off of $4,994 was subsequently recorded in commercial and industrial loans. No interest income was recognized on these loans as they were accounted for as non-accrual during the period. There are no outstanding commitments on these loans as of December 31, 2019.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	NOTE 9 – DERIVATIVE FINANCIAL INSTRUMENTS Interest Rate Swaps Designated as Fair Value Hedges The Company periodically enters into interest rate swaps to hedge the fair value of certain commercial real estate loans. These transactions are designated as fair value hedges. In this type of transaction, the Company typically receives from the counterparty a variable-rate cash flow based on the one-month London Interbank Offered Rate (LIBOR) plus a spread to this index and pays a fixed-rate cash flow equal to the customer loan rate. At December 31, 2019, the portfolio of interest rate swaps had a weighted average maturity of 7.3 years, a weighted average pay rate of 5.19% and a weighted average rate received of 4.78%. At December 31, 2018, the portfolio of interest rate swaps had a weighted average maturity of 7.7 years, a weighted average pay rate of 4.94% and a weighted average rate received of 5.10%. Stand-Alone Derivatives The Company periodically enters into interest rate swaps with our borrowers and simultaneously enters into swaps with a counterparty with offsetting terms for the purpose of providing our borrowers long-term fixed rate loans. Neither swap is designated as a hedge and both are marked to market through earnings. At December 31, 2019, this portfolio of interest rate swaps had a weighted average maturity of 8.8 years, weighed average pay rate of 4.92% and a weighted rate received of 4.92%. At December 31, 2018, this portfolio of interest rate swaps had a weighted average maturity of 7.6 years, weighted average pay rate of 5.18% and a weighted rate received of 5.18%. In 2009, the Company purchased an interest rate cap derivative to assist with interest rate risk management. This derivative is not designated as a hedging instrument but rather as a stand-alone derivative. During 2019, the interest rate cap derivative matured. At December 31, 2018, the interest rate cap had a term of 0.9 years and a cap rate of 4.50%. Reconciliation of Derivative Fair Values and Gains/(Losses) The notional amount of a derivative contract is a factor in determining periodic interest payments or cash flows received or paid. The notional amount of derivatives serves as a level of involvement in various types of derivatives. The notional amount does not represent the Company’s overall exposure to credit or market risk, generally, the exposure is significantly smaller. The following table shows the notional balances and fair values (including net accrued interest) of the derivatives outstanding by derivative type at December 31, 2019 and December 31, 2018.

The Company accounted for the effects of Tax Reform in the period of enactment as required by generally accepted accounting principles using reasonable estimates based on information available in December 2017. The Company completed its accounting for the effects of Tax Reform in 2018, and no additional income tax expense was recorded. The direct impact to the 2017 financial statements was the re-measurement of the Company’s December 31, 2017, deferred tax assets and liabilities which were expected to reverse beginning in 2018. The re-measurement of the Company’s net deferred tax asset resulted in $1,086 additional income tax expense being recognized in 2017, including a $535 decrease in the net deferred tax assets related to unrealized or unamortized losses on securities. The impact of this re-measurement is included in the statutory rate reconciliation above. With the exception of the revaluation adjustment required by Tax Reform, the deferred tax effects of unrealized or unamortized gains and losses on debt securities are recorded directly to stockholders’ equity as part of other comprehensive income. Components of deferred tax assets and liabilities are shown in the table below. 2019 2018 Deferred tax assets Allowance for loan losses $ 3,076 $ 2,880 Net unrealized or unamortized losses on securities 1 1,639 Tax credit carryforwards 974 974 Accrued compensation 2,209 1,994 Net operating loss carryforwards 1,337 1,003 Other real estate owned 481 656 Acquired loans fair market value adjustments 2,560 4,058 Other 1,153 1,072 Gross deferred tax assets 11,791 14,276 Deferred tax liabilities Assumed debt fair market value adjustments 1,464 1,537 Goodwill amortization 1,871 1,492 Depreciation 3,934 3,288 Federal Home Loan Bank stock dividends 267 1,123 Core deposit intangibles 3,616 4,293 Other 981 283 Gross deferred tax liabilities 12,133 12,016 Valuation allowance (1,623 ) (1,227 ) Net deferred tax asset (liability) $ (1,965 ) $ 1,033 Deferred income tax balances reflect the effects of temporary differences between the carrying amounts of assets and liabilities and their tax basis and are stated at enacted tax rates expected to be in effect when taxes are actually paid or recovered. In 2019, the Company recognized deferred tax liabilities of $21 for temporary differences associated with the MidFirst bank acquisition. In 2018, the Company recognized deferred tax assets of $2,522 and deferred tax liabilities of $2,190 for temporary differences associated with the KBC merger and deferred tax assets of $1,134 and deferred tax liabilities of $518 for temporary differences associated with the Adams merger. Deferred tax assets of $34 were recognized in connection with the CBT merger. Federal net operating losses, acquired through previous acquisitions, totaled $196 at December 31, 2019 and will expire between 2031 and 2033. Acquired federal tax credits totaling $974 will expire between 2027 and 2033. The utilization of these net operating loss and tax credit carryforwards are not expected to be limited by internal revenue code sections 382 and 383. The Company and its subsidiaries are subject to U.S. federal income tax as well as income tax of the states of Arkansas, Kansas, Missouri, Oklahoma and Iowa. Commercial banks are not allowed to file consolidated Kansas returns with non-bank consolidated group members. The Company has unused state operating loss carryforwards of approximately $30,254 that expire between 2020 and 2029 resulting from the separate Kansas returns of the Company and SA Holdings, Inc. These operating losses, as well as certain deferred tax assets, have a full valuation allowance recorded against them resulting in a zero carrying value. In connection with a 2015 acquisition, the Company acquired Kansas net operating losses useable against Kansas bank income. At December 31, 2019, the Kansas net operating loss carryforward useable against Kansas bank income totaled $2,469 with expiration dates between 2020 and 2024. The utilization of this acquired Kansas net operating loss carryforward is expected to be limited, and a valuation allowance has been recorded against the portion which is expected to expire unused. In establishing a valuation allowance management considers whether it is more likely than not that some or all of the deferred tax assets will not be realized. The Company is no longer subject to examination by taxing authorities for years before 2016. At December 31, 2019, there were no examinations in any jurisdiction.

Banking And Thrift [Abstract]
REGULATORY MATTERS	NOTE 16 – REGULATORY MATTERS Banks and bank holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action. The final rules implementing the Basel Committee on Banking Supervision’s capital guidelines for U.S. banks (Basel III rules) became effective for the Company on January 1, 2015, with full compliance with all of the requirements being phased in over a multi-year schedule, and fully phased in January 1, 2019. The Basel III rules also require banks to maintain a Common Equity Tier 1 capital ratio of 6.5%, a total Tier 1 capital ratio of 8%, a total capital ratio of 10% and a leverage ratio of 5% to be deemed “well capitalized” for purposes of certain rules and prompt corrective action requirements. The risk-based ratios include a “capital conservation buffer” of 2.5%. The new capital conservation buffer requirement was to be phased in beginning January 2016 at 0.625% of risk-weighted assets and increased by that amount each year until fully implemented January 2019. An institution is subject to limitations on certain activities, including payment of dividends, share repurchases and discretionary bonuses to executive officers, if its capital level is below the buffer amount. Management believes as of December 31, 2019, the Company and Bank meet all capital adequacy requirements to which they are subject. Prompt corrective action regulations provide five classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized and critically undercapitalized, although these terms are not used to represent overall financial condition. If adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as are asset growth and acquisitions and capital restoration plans are required. As of December 31, 2019, the most recent notifications from the federal regulatory agencies categorized Equity Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, Equity Bank must maintain minimum total risk-based, Tier 1 risk-based and Tier 1 leverage ratios as set forth in the table. There are no conditions or events since that notification that management believes have changed Equity Bank’s category. The Company’s and Equity Bank’s capital amounts and ratios at December 31, 2019 and 2018 are presented in the tables below.

Compensation And Retirement Disclosure [Abstract]
EMPLOYEE BENEFITS	NOTE 18 – EMPLOYEE BENEFITS The Company has a defined contribution profit sharing plan and a retirement savings 401(k) plan covering substantially all employees. Employees may contribute up to $19 of their compensation. Contributions to the profit-sharing plan and 401(k) plan are discretionary and are determined annually by the Board of Directors. Employer contributions charged to expense for 2019, 2018 and 2017 were $826, $885 and $704. As a result of the acquisition of First Independence, the Company assumed the obligations related to First Independence’s participation in the Pentegra Defined Benefit Plan for Financial Institutions, a tax-qualified defined benefit pension plan. The Pentegra Defined Benefit Plan is treated as a multi-employer plan for accounting purposes but operates as a multiple-employer plan under the Employee Retirement Income Security Act of 1974 (ERISA) and the Internal Revenue Code. As a result, certain multi-employer plan disclosures are not applicable to the Pentegra Defined Benefit Plan. Under the Pentegra Defined Benefit Plan, contributions made by a participating employer may be used to provide benefits to employees of other participating employers because assets contributed by an employer are not segregated in a separate account or restricted to provide benefits only to employees of that employer. Also, in the event a participating employer is unable to meet its contribution requirements, the required contributions for the other participating employers could increase proportionately. The Pentegra Defined Benefit Plan covered substantially all officers and employees of First Independence who began employment prior to December 31, 2009, with 54 participants retaining benefits under the plan. The Pentegra Defined Benefit Plan operates on a fiscal year from July 1 through June 30 and files one Form 5500 on behalf of all employers who participate in the plan. The Employer Identification Number is 13-5645888 and the three-digit plan number is 333. There are no collective bargaining agreements in place at the Company. The Pentegra Defined Benefit Plan’s annual valuation process includes calculating the plan’s funded status and separately calculating the funded status of each participating employer. The funded status is defined as the market value of assets divided by the funding target (100 percent of the present value of all benefit liabilities accrued at that date). As permitted by ERISA, the Pentegra Defined Benefit Plan accepts contributions for the prior plan year up to eight and a half months after the asset valuation date. As a result, the fair value of assets at the valuation date (July 1) will increase by any subsequent contributions designated for the immediately preceding plan year ended June 30. The most recent Form 5500 available for the Pentegra Defined Benefit Plan is for the year ended June 30, 2018. The following table presents the net pension cost and funded status of the Company relating to the Pentegra Defined Benefit Plan since the date of acquisition (dollar amounts in thousands). 2019 2018 Net pension cost charged to salaries and employee benefits $ 142 $ 113 Pentegra defined benefit plan funded status as of July 1 108.59 % 109.86 % Plan's funded status as of July 1 91.40 % 94.30 % Contributions paid to the plan $ 109 $ 93 The Company’s contributions to the Pentegra Defined Benefit Plan were less than 5.00% of the total contributions to the Pentegra Defined Benefit plan for the plan year ended June 30, 2018.

SHARE-BASED PAYMENTS	NOTE 19 – SHARE-BASED PAYMENTS The Company’s Amended and Restated 2013 Stock Incentive Plan (the Plan) reserved 1,500,000 shares for the grant of non-qualified stock options, restricted stock units, restricted stock and unrestricted stock to its employees and directors. The Plan replaced the 2006 Non-qualified Stock Option Plan (2006 Plan). Under the 2006 Plan, there were 150,000 and 150,000 fully vested and exercisable options outstanding at December 31, 2019 and 2018. No new grants of options may be made under the 2006 Plan. The Company believes that stock-based awards better align the interests of its employees with those of its stockholders. Under the Company’s 2019 director compensation policy, the directors receive a portion of their compensation in stock. The Company recognized expense of $160 and issued 9,104 shares for the year ended December 31, 2019. For years prior to 2019, the directors could elect to receive all or a portion of their fees in cash, Company stock or non-qualified stock options. During the years ended December 31, 2018 and 2017, the Company recognized director compensation expense of $53 and $46 and issued 1,375 and 1,457 shares of Company stock pursuant to certain directors’ elections. At December 31, 2019, there were 572,745 shares available for equity awards under the Plan. Stock Option Awards The following tables summarize stock option activity for the years ended December 31, 2019 and 2018.

The Company recognized share-based compensation attributable to RSUs of $1,991, $1,643 and $80 for the years ended December 31, 2019, 2018 and 2017. The total income tax benefit was $501, $413 and $31 for the same time periods. Unrecognized RSU compensation expense of $4.1 million at December 31, 2019, will be recognized over a remaining weighted average period of 2 years. Employee Stock Purchase Plan On January 27, 2019, the Company’s Board of Directors adopted the Equity Bancshares, Inc. 2019 Employee Stock Purchase Plan (“ESPP”) and reserved 500,000 shares of common stock for issuance. The ESPP was approved by the Company’s stockholders on April 24, 2019. The ESPP enables eligible employees to purchase the Company’s common stock at a price per share equal to 85% of the lower of the fair market value of the common stock at the beginning or end of each offering period. The first offering period began on February 15, 2019 and ended on August 14, 2019. In connection with the first offering, a total of 19,221 shares were purchased at a price of $21.07 per share. The second offering period began on August 15, 2019 and will end February 14, 2020. ESPP compensation expense of $119 was recorded during 2019.

FAIR VALUE

Fair Value Disclosures [Abstract]
FAIR VALUE	NOTE 21 – FAIR VALUE The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to disclose the fair value of its financial instruments. Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. For disclosure purposes, the Company groups its financial and non-financial assets and liabilities into three different levels based on the nature of the instrument and the availability and reliability of the information that is used to determine fair value. The three levels of inputs that may be used to measure fair values are defined as follows. Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. Level 1 inputs are considered to be the most transparent and reliable. The Company assumes the use of the principal market to conduct a transaction of each particular asset or liability being measured and then considers the assumptions that market participants would use when pricing the asset or liability. Whenever possible, the Company first looks for quoted prices for identical assets or liabilities in active markets (Level 1 inputs) to value each asset or liability. However, when inputs from identical assets or liabilities on active markets are not available, the Company utilizes market observable data for similar assets and liabilities. The Company maximizes the use of observable inputs and limits the use of unobservable inputs to occasions when observable inputs are not available. The need to use unobservable inputs generally results from the lack of market liquidity of the actual financial instrument or of the underlying collateral. Although, in some instances, third party price indications may be available, limited trading activity can challenge the implied value of those quotations. The following is a description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of each instrument under the hierarchy. Fair Value of Assets and Liabilities Measured on a Recurring Basis The fair values of available-for-sale securities are carried at fair value on a recurring basis. To the extent possible, observable quoted prices in an active market are used to determine fair value and, as such, these securities are classified as Level 1. For securities where quoted prices are not available, fair values are calculated based on market prices of similar securities, generally determined by matrix pricing, which is a mathematical technique widely used in the industry to value securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs). The Company’s available-for-sale securities includes residential mortgage-backed securities (all of which are issued or guaranteed by government sponsored agencies) and are classified as Level 2. The fair values of derivatives are determined based on a valuation pricing model using readily available observable market parameters such as interest rate yield curves (Level 2 inputs) adjusted for credit risk attributable to the seller of the derivative. Assets and liabilities measured at fair value on a recurring basis are summarized below. December 31, 2019 (Level 1) (Level 2) (Level 3) Assets: Available-for-sale securities: Residential mortgage-backed securities (issued by government-sponsored entities) $ — $ 142,067 $ — Derivative assets: Derivative assets (included in other assets) — 3,535 — Cash collateral held by counterparty and netting adjustments 182 — — Total derivative assets 182 3,535 — Other assets: Equity securities with readily determinable fair value 489 — — Total other assets 489 — — Total assets $ 671 $ 145,602 $ — Liabilities: Derivative liabilities: Derivative liabilities (included in other liabilities) $ — $ 4,076 $ — Cash collateral held by counterparty and netting adjustments (4,004 ) — — Total derivative liabilities (4,004 ) 4,076 — Total liabilities $ (4,004 ) $ 4,076 $ — December 31, 2018 (Level 1) (Level 2) (Level 3) Assets: Available-for-sale securities: Residential mortgage-backed securities (issued by government-sponsored entities) $ — $ 168,875 $ — Derivative assets: Derivative assets (included in other assets) — 933 — Cash collateral held by counterparty and netting adjustments (242 ) — — Total derivative assets (242 ) 933 — Other assets: Equity securities with readily determinable fair value 475 — — Total other assets 475 — — Total assets $ 233 $ 169,808 $ — Liabilities: Derivative liabilities: Derivative liabilities (included in other liabilities) $ — $ 777 $ — Cash collateral held by counterparty and netting adjustments (252 ) — — Total derivative liabilities (252 ) 777 — Total liabilities $ (252 ) $ 777 $ — There were no transfers between Levels during 2019 or 2018. The Company’s policy is to recognize transfers into or out of a level as of the end of a reporting period. Fair Value of Assets and Liabilities Measured on a Non-recurring Basis Certain assets are measured at fair value on a non-recurring basis when there is evidence of impairment. The fair values of impaired loans with specific allocations of the allowance for loan losses are generally based on recent real estate appraisals of the collateral. Declines in the fair values of other real estate owned subsequent to their initial acquisitions are also based on recent real estate appraisals less selling costs. Real estate appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are typically significant and result in a Level 3 classification of the inputs for determining fair value. Assets measured at fair value on a non-recurring basis are summarized below. December 31, 2019 (Level 1) (Level 2) (Level 3) Impaired loans: Commercial real estate $ — $ — $ 2,411 Commercial and industrial — — 15,688 Residential real estate — — 2,920 Agricultural real estate — — 866 Other — — 1,549 Other real estate owned: Commercial real estate — — 1,268 Residential real estate — — 42 December 31, 2018 (Level 1) (Level 2) (Level 3) Impaired loans: Commercial real estate $ — $ — $ 6,212 Commercial and industrial — — 1,697 Residential real estate — — 4,123 Agricultural real estate — — 218 Other — — 809 Other real estate owned: Commercial real estate — — 1,391 Residential real estate — — 97 The Company did not record any liabilities for which the fair value was measured on a non-recurring basis during the years ended December 31, 2019 and 2018. Valuations of impaired loans and other real estate owned utilize third party appraisals or broker price opinions and are classified as Level 3 due to the significant judgment involved.

Commitments And Contingencies Disclosure [Abstract]
COMMITMENTS AND CREDIT RISK	NOTE 22 – COMMITMENTS AND CREDIT RISK The Company extends credit for commercial real estate mortgages, residential mortgages, working capital financing and loans to businesses and consumers. Commitments to Originate Loans and Available Lines of Credit: Commitments to originate loans and available lines of credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments and lines of credit generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since a portion of the commitments and lines of credit may expire without being drawn upon, the total commitment and lines of credit amounts do not necessarily represent future cash requirements. Each customer’s creditworthiness is evaluated on a case-by-case basis. The amount of collateral obtained, if deemed necessary, is based on management’s credit evaluation of the counterparty. Collateral held varies, but may include accounts receivable, inventory, property, plant and equipment, commercial real estate, and residential real estate. Mortgage loans in the process of origination represent amounts that the Company plans to fund within a normal period of 60 to 90 days and are intended for sale to investors in the secondary market. The contractual amounts of commitments to originate loans and available lines of credit as of December 31, 2019 and 2018 were as follows. December 31, 2019 December 31, 2018 Fixed Rate Variable Rate Fixed Rate Variable Rate Commitments to make loans $ 41,916 $ 141,685 $ 29,543 $ 171,857 Mortgage loans in the process of origination 9,200 2,473 6,785 2,860 Unused lines of credit 95,866 150,749 92,225 167,218 At December 31, 2019, the fixed rate loan commitments have interest rates ranging from 3.75% to 8.09% and maturities ranging from 1 month to 84 months. Standby Letters of Credit: Standby letters of credit are irrevocable commitments issued by the Company to guarantee the performance of a customer to a third party once specified pre-conditions are met. Financial standby letters of credit are primarily issued to support public and private borrowing arrangements, including commercial paper, bond financing, and similar transactions. Performance standby letters of credit are issued to guarantee performance of certain customers under non-financial contractual obligations. The credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending loans to customers. The contractual amounts of standby letters of credit as of December 31, 2019 and 2018 are listed below.

LEGAL MATTERS	NOTE 23 – LEGAL MATTERS The Company is party to various matters of litigation in the ordinary course of business. The Company periodically reviews all outstanding pending or threatened legal proceedings and determines if such matters will have an adverse effect on the business, financial condition or results of operations or cash flows. A loss contingency is recorded when the outcome is probable and reasonably able to be estimated. The following loss contingencies have been identified by the Company as reasonably possible to result in an unfavorable outcome for the Company or the Bank. Equity Bank is a party to a February 3, 2015, lawsuit filed against it by CitiMortgage, Inc. (“Citi”). The lawsuit involves an alleged breach of contract related to loan repurchase obligations and damages of $2,700 plus pre-judgment and post-judgment interest. In January 2018, judgment was entered by the court dismissing Citi’s claims with regard to six loans and holding Equity Bank liable with regard to six loans. A loss contingency of $477 was recorded at December 31, 2017, in connection with this case. Subsequently Citi appealed the court’s decision. On November 6, 2019, the Eighth Circuit Court of Appeals issued a decision affirming the trial court’s findings dismissing Citi’s claims with regard to six loans and holding Equity Bank liable with regard to six loans. Citi unsuccessfully sought en banc review of the portion of the Court’s ruling in Equity’s favor. As a result of the Eighth Circuit’s ruling, Equity Bank will be required to satisfy the total judgement of $1,474, but shall be entitled to a reassignment of loans in which there is existing collateral. At the time of this January 2018 judgment, Citi held four loans with collateral having a total balance of $1,129; however, at this time, the Company does not have access to more recent loan information, such as, loan balance, loan status or collateral value to reassess the loss contingency that was recorded at December 31, 2017. Except for the above-mentioned lawsuit and settlement, there have been no other claims for potential repurchase or indemnification demands regarding mortgage loans originated by Equity Bank and sold to investors. However, the Company believes there is possible risk it may face similar demands based on comparable demands loan aggregators are facing from their investors, including Government Sponsored Entities such as Freddie Mac and Fannie Mae and/or settlement agreements loan aggregators have entered into with those investors. The amount of potential loss and outcome of such possible litigation, if it were commenced, is uncertain and the Company would vigorously contest any claims. On May 13, 2019, a purported stockholder of the Company filed a putative securities class action lawsuit in federal court in the Southern District of New York against the Company and certain of its executive officers. On August 16, 2019, the court appointed lead plaintiffs and on October 15, 2019, the plaintiffs filed an amended complaint on behalf of a putative class of persons who purchased Company securities between April 20, 2018, and April 23, 2019. Plaintiffs allege that the Company made materially misleading statements about the Company’s financial results, business, operations and prospects starting on April 20, 2018, that these statements caused the Company’s securities to be overvalued and that the “truth” came out on January 24, 2019, when the Company disclosed that a credit relationship was downgraded and further on April 22, 2019, when the Company disclosed a $14,500 provision for loan loss against that credit relationship. On December 6, 2019, the Company filed a motion to dismiss which remains pending before the court. The Company believes that the lawsuit is without merit and it intends to vigorously defend against all claims asserted. At this time, the Company is unable to reasonably estimate the outcome of this litigation.

Revenue From Contract With Customer [Abstract]
REVENUE RECOGNITION	NOTE 24 – REVENUE RECOGNITION The majority of the Company’s revenues come from interest income on financial instruments, including loans, leases, securities and derivatives, which are outside the scope of ASC 606. The Company’s services that fall within the scope of ASC 606 are presented with non-interest income and are recognized as revenue as the Company satisfies its obligation to the customer. Services within the scope of ASC 606 include service charges and fees on deposits, debit card income, investment referral income, insurance sales commissions and other non-interest income related to loans and deposits. Except for gains or losses from the sale of other real estate owned, all of the Company’s revenue from contracts with customers within the scope of ASC 606 is recognized in non-interest income. The following table presents the Company’s sources of non-interest income for the years ended December 31, 2019, and 2018. 2019 2018 Non-interest income Service charges and fees $ 8,672 $ 7,250 Debit card income 8,230 6,178 Mortgage banking (a) 2,468 1,298 Increase in bank-owned life insurance (a) 1,998 2,199 Net gain (loss) from securities transactions (a) 14 (9 ) Other Investment referral income 590 395 Trust income 243 81 Insurance sales commissions 177 245 Recovery on zero-basis purchased loans (a) 143 420 Income from equity method investments (a) 26 7 Other non-interest income related to loans and deposits 2,340 1,612 Other non-interest income not related to loans and deposits(a) 87 49 Total other non-interest income 3,606 2,809 Total $ 24,988 $ 19,725 (a) A description of the Company’s revenue streams accounted for under ASC 606 follows. Service Charges and Fees The company earns fees from its deposit customers for transaction-based, account maintenance and overdraft services. Transaction-based fees, which include services such as stop payment charges, statement rendering and ACH fees, are recognized at the time the transaction is executed as that is the point in time the Company fulfills the customer’s request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which the Company satisfies the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are collected through withdrawal from the customer’s account balance. Debit Card Income The Company earns debit card income from cardholder transactions conducted through payment processors. Debit card income from cardholder transactions represent a percentage of the underlying transaction value and are recognized concurrently with the transaction processing services provided to the cardholder. Investment Referral Income Investment referral services are offered through an unaffiliated registered broker-dealer and investment advisor. Investment referral income consists of transaction-based fees (i.e., trade commissions) and account fees (i.e., custodial fees). The service obligation for transaction-based fees relates to processing of individual transactions and is considered earned at the time the transaction occurs. The Company currently records this income when payment is received and at each month end for current-month transactions. Account fees are considered earned over the period for which the fees relate. These fees are received during the first month of each quarter and represent advance payment for the current quarter. These fees are amortized ratably over the three months during the quarter. Therefore, all account-based fees are currently recorded as performance obligations are satisfied. Trust Income Trust income includes fees from asset management, custody, recordkeeping, investment advisory and administration services. Revenue is recognized at the time the services are performed and may be based on either the fair value of the account or the services provided. Insurance Sales Commissions Insurance commissions are received based on contracts with insurance companies which provide for a percentage of premiums to be paid to the Company in exchange for placement of policies with customers. The commissions generally relate to a period of one year or less. Under certain contracts, the Company may also assist with the claims processing, but this performance obligation is considered insignificant compared to the initial placement of the policy. As such, the performance obligation is considered to have been substantially satisfied at the time of policy placement. While this indicates that all related revenue would be appropriately accrued at policy inception, in some cases recognition occurs over the policy period if received in installments from the insurance company. In no cases would this deferral extend beyond 12 months and the effect is considered immaterial compared to recognition at the time of policy placement. The Company also receives commissions based on renewals of policies previously placed. However, additional work is required to process the renewals, resulting in future performance obligations to earn the related revenues. In addition, the occurrence of such renewals is not certain as initial policies are generally for one year or less and the fees earned are not determined until the time of renewal, based on underwriting at that time. As such, the Company has determined that accrual of income for future renewals is not appropriate. Other non-interest Income Other non-interest income related to loans and deposits is earned when the specific transaction is processed, similar to service charges and fees. Gain of Loss on Sale of Other Real Estate Gain or loss on sale of other real estate is reported in non-interest expense and is netted with other real estate expenses. The Company records a gain or loss from the sale of other real estate when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. When the Company finances the sale of other real estate to the buyer, the Company assesses whether the buyer is committed to perform their obligation under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the other real estate is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on the sale, the Company adjusts the transaction price and related gain or loss on sale if a significant financing component is present. As a result, the Company has concluded that ASC 606 will affect the decision to recognize or defer gains on sales of other real estate in circumstances where the Company has financed the sale.

NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended

Accounting Policies [Abstract]
Nature of Operations	Nature of Operations Equity Bank is a Kansas state-chartered bank and member of the Federal Reserve (state Fed member bank jointly supervised by both the Federal Reserve Bank of Kansas City and the Office of the Kansas State Bank Commissioner). The Company is primarily engaged in providing a full range of banking, mortgage banking and financial services to individual and corporate customers generally in Arkansas, Kansas, Missouri and Oklahoma. Equity Bank competes with a variety of other financial institutions including large regional banks, community banks and thrifts as well as credit unions and other non-traditional lenders.
Use of Estimates	Use of Estimates
Cash Equivalents	Cash Equivalents
Securities	Securities Interest income includes amortization of purchase premium or discount. Premiums and discounts on securities are amortized on the level-yield basis without anticipating prepayments, except for certain securities where prepayments are anticipated. Gains and losses on sales are recorded on the trade date and determined using the specific identification method. Management evaluates securities for other-than-temporary impairment (“OTTI”) on at least a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. For securities in an unrealized loss position, management considers the extent and duration of the unrealized loss and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or it is more likely than not that it will be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: 1) OTTI related to credit loss, which must be recognized in the income statement and 2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. All OTTI related to equity securities is recognized through earnings. Equity investments with a readily determinable fair value are measured at fair value with changes in fair value recognized in net income. The exit price concept is used when measuring the fair value of financial instruments for disclosure purposes.
Loans Held for Sale	Loans Held for Sale
Loans	Loans Purchased Credit Impaired Loans. As a part of acquisitions, the Company acquired certain loans, for which there was, at acquisition, evidence of deterioration of credit quality since origination. These purchased credit impaired loans were recorded at the acquisition date fair value, such that there is no carryover of the seller’s allowance for loan losses. After acquisition, losses are recognized by an increase in the allowance for loan losses. Such purchase credit impaired loans are accounted for individually. The Company estimates the amount and timing of expected cash flows for each loan, and the expected cash flows in excess of the amount paid are recorded as interest income over the remaining life of the loan (accretable yield). During acquisitions, if the Company expects to liquidate the loan collateral in a relatively short period of time, the Company will assign no value to accretable yield as the impact is immaterial. The excess of the loan’s contractual principal and interest over expected cash flows is not recorded (non-accretable difference). Over the life of the loan, expected cash flows continue to be estimated. If the present value of the expected cash flows is less than the carrying amount, a loss is recorded. If the present value of the expected cash flows is greater than the carrying amount, it is recognized as part of future interest income. Nonaccrual Loans. Generally, loans are designated as nonaccrual when either principal or interest payments are 90 days or more past due based on contractual terms unless the loan is well secured and in the process of collection. Consumer loans are typically charged-off no later than 180 days past due. In all cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. When a loan is placed on nonaccrual status, unpaid interest credited to income is reversed against income. Future interest income may be recorded on a cash basis after recovery of principal is reasonably assured. Nonaccrual loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Impaired Loans. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all contractual principal and interest due according to the terms of the loan agreement. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate or on the value of the underlying collateral if the loan is collateral dependent. The Company evaluates the collectability of both principal and interest when assessing the need for a loss accrual. Factors considered by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. Troubled Debt Restructurings . In cases where a borrower experiences financial difficulties and the Company makes certain concessionary modifications to contractual terms, the loan is classified as a troubled debt restructured loan and classified as impaired. Generally, a nonaccrual loan that is a troubled debt restructuring remains on nonaccrual until such time that repayment of the remaining principal and interest is not in doubt and the borrower has a period of satisfactory repayment performance.
Allowance for Loan Losses	Allowance for Loan Losses The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. If a loan is impaired, a portion of the allowance is allocated so that the loan is reported net at the present value of estimated future cash flows using the loan’s existing rate or at the fair value of collateral if repayment is expected solely from the sale of the collateral. Troubled debt restructurings are separately identified for impairment disclosures and are measured at the present value of estimated future cash flows using the loan’s effective rate at inception. If a troubled debt restructuring is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of the collateral. For troubled debt restructurings that subsequently default, the Company determines the amount of reserve in accordance with the accounting policy for the allowance for loan losses. The general component of the allowance for loan losses covers non-impaired loans and is based on historical loss experience adjusted for current factors. The historical loss experience is determined by portfolio and class and is based on the actual loss history experienced by the Company. This actual loss experience is then adjusted by comparing current conditions to the conditions that existed during the loss history. The Company considers the changes related to (i) lending policies, (ii) economic conditions, (iii) nature and volume of the loan portfolio and class, (iv) lending staff, (v) volume and severity of past due, non-accrual and risk graded loans, (vi) loan review system, (vii) value of underlying collateral for collateral dependent loans, (viii) concentration levels and (ix) effects of other external factors. The Company considers loan performance and collateral values in assessing risk for each class in the loan portfolio, as follows: • Commercial and industrial loans are dependent on the strength of the industries of the related borrowers and the success of their businesses. Commercial and industrial loans are advanced for equipment purchases, to provide working capital or meet other financing needs of the business. These loans may be secured by accounts receivable, inventory, equipment or other business assets. Financial information is obtained from the borrower to evaluate the debt service coverage and ability to repay the loans. • Commercial real estate loans are dependent on the industries tied to these loans, as well as the local commercial real estate market. The loans are secured by real estate and typically appraisals are obtained to support the loan amount. Generally, an evaluation of the project’s cash flows is performed to evaluate the borrower’s ability to repay the loan at the time of origination and periodically updated during the life of the loan. • Residential real estate loans are affected by the local residential real estate market, the local economy and movement in interest rates. The Company evaluates the borrower’s repayment ability through a review of credit reports and debt to income ratios. Generally, appraisals are obtained to support the loan amount. • Agricultural real estate loans are real estate loans related to farmland and are affected by the value of farmland. Generally, the Company evaluates the borrower’s ability to repay based on cash flows from farming operations. • Consumer loans are dependent on the local economy. Consumer loans are generally secured by consumer assets, but may be unsecured. Typically, the Company evaluates the borrower’s repayment ability through a review of credit scores and an evaluation of debt to income ratios. • Agricultural loans are primary operating lines subject to annual farming revenues, including productivity and yield of the farm products and market pricing at the time of sale. There have been no material changes to the Company’s accounting policies related to its allowance for loan loss methodology during 2019 and 2018.

Premises and Equipment	Premises and Equipment Premises and equipment and other long-term assets are reviewed for impairment when events indicate their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value. Lease Obligation. The Company evaluates contracts that convey the right to control the use of identified property, plant or equipment for a period of time for consideration to determine if they are lease obligations. The Company evaluates each lease component to determine if the lease qualifies as a financing lease or as an operating lease. Leases that meet any of the following criteria are considered financing leases: (1) the lease transfers ownership of the underlying asset by the end of the lease term; (2) the lease grants the Company an option to purchase the underlying asset that the Company is reasonably certain to exercise; (3) the lease term is the major part of the remaining economic life of the underlying asset; (4) the present value of the sum of the lease payments and any residual value guaranteed by the Company that is not already reflected in lease payments equals or exceeds substantially all of the fair of the underlying asset; or (5) the underlying asset is of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term. If none of the financing lease criteria are met, the lease is considered an operating lease. The Company evaluates each lease to determine the lease term which will be used based on the type and use of the leased equipment and future expected changes in operations. The resulting lease term will consist of the non-cancellable period for which the Company has the right to use the underlying asset plus (1) periods covered by an option to extend the lease if the Company is reasonably certain to exercise that option; (2) periods covered by an option to terminate the lease if the Company is reasonably certain not to exercise that option; and (3) periods covered by an option to extend the lease in which exercise of the option is controlled by the lessor. The Company has certain leases that contain options to extend the lease and contain options for changes in lease payments which are evaluated by the Company to determine the recorded values for right-of-use assets and lease liability. Lease payments that are contractually known at lease inception are used by the Company for calculating the right-of-use asset and lease liability. Lease payments that vary because of facts or circumstances after the commencement date of the lease from other than passage of time are treated as variable lease payments and are recorded to lease expense in the period in which the obligation for the payments are incurred by the Company. Variable lease payments are not part of the lease payments for determining the right-of-use asset or the lease liability at the lease commencement date. The discount rate to initially determine the present value of the lease payments is based on the information available at the lease commencement date and is either the rate implicit in the lease or the Company’s incremental borrowing rate If the rate implicit in the lease is known or determinable, that rate shall be used. If that rate is not known, the Company’s incremental borrowing rate shall be used. At the January 2019, implementation of this accounting guidance, the Company’s incremental borrowing rate based on the remaining lease term was used to calculate the right-of-use assets and operating lease liabilities. Operating lease right-of-use assets and lease obligations are accounted for subsequent to initial recording by amortizing the right-of-use asset over the lease term on a straight-line method while the lease obligation is increased by the accrual of interest and decreased by subsequent lease payments. Operating lease right-of-use asset amortization and lease obligation interest are reported in non-interest expense in the Consolidated Statements of Operations. Operating lease payments and variable lease payments are reflected within cash flows from operating activities in the Consolidated Statement of Cash Flows. Financing lease right-of-use assets and lease obligations are accounted for subsequent to initial recording by amortizing the right-of-use asset similar to owned assets over the lesser of the lease term or economic life of the asset if the lease transfers ownership of the leased asset while the lease obligation is increased by the accrual of interest and decreased by subsequent lease payments. Financing lease right-of-use asset amortization is reported in non-interest expense, similar to other owned assets, and lease obligation interest accruals are reported in interest expense in the Consolidated Statements of Operations. Financing lease obligation principal payments are reflected within cash flows from financing activities and interest payments and variable lease payments are reflected with the cash flows from operating activities in the Consolidated Statements of Cash Flows. The Company evaluates lease modifications and will consider the modification a new contract if the modification grants the lessee an additional right of use not included in the original lease and the lease payments increase commensurate with the stand-alone price for the additional right-of-use asset. The Company will reallocate the remaining consideration in the contract and remeasure the lease liability using a discount rate for the lease determined at the effective date of the lease modification if the contract modification does any of the following: (1) grants the Company an additional right of use that was not included in the original contract; (2) extends or reduces the term of an existing lease; (3) fully or partially terminates an existing lease; or (4) changes the consideration in the contract only. The Company will recognize the remeasurement of the lease liability for the modification as an adjustment of the right-of-use asset when the contract modification grants additional right-of-use-assets, extends or reduces the term of the lease or changes the consideration of the lease contract. In the case of full or partial termination of the lease, the Company will decrease the carrying amount of the right-of-use-asset on a proportionate basis to the reduction in the lease liability with a gain or loss recognized for the difference between the lease liability adjustment and right of use asset adjustment. If the Company modifies an operating lease which it is the lessor and the modification is not accounted for as a separate contract, the Company will account for the modification as if it were a termination of the existing lease and the creation of a new lease that commences on the effective date of the modification as follows: • If the modified lease is classified as an operating lease, the Company will consider any prepaid or accrued lease rentals relating to the original lease as part of the lease payments for the modified lease. • If the modified lease is classified as a direct financing lease or a sales-type lease, the Company will derecognize any deferred rent liability or accrued rent asset and adjust the selling profit or loss. If the Company modifies a direct financing lease which it is the lessor and the modification is not accounted for as a separate contract, the Company will account for the modified lease as follows: • If the modified lease is classified as a direct financing lease, the Company will adjust the discount rate for the modified lease, so the initial net investment equals the carrying amount of the original lease at the modification effective date. • If the modified lease is classified as a sales-type lease, the Company shall determine the selling profit/loss on commencement date of the modified lease as the difference between the fair value of the underlying asset and net investment in the original lease prior to modification. • If the modified lease is classified as an operating lease, the carrying amount of the underlying asset shall equal the net investment in the original lease immediately before the effective date of the modification. If the Company modifies a sales-type lease which it is the lessor and the modification is not accounted for as a separate contract, the Company will account for the modified lease as follows: • If the modified lease is classified as a direct financing lease, the Company will adjust the discount rate for the modified lease, so the initial net investment of the modified lease equals the carrying amount of the original lease at the modification effective date. • If the modified lease is classified as a direct financing lease, the Company will adjust the discount rate for the modified lease, so the initial net investment equals the carrying amount of the original lease at the modification effective date.

Derivatives	Derivatives An interest rate swap is an agreement between two entities to exchange cash flows in the future. The agreement sets the dates on which the cash flows will be paid and the manner in which the cash flows will be calculated. Typically, an interest rate swap transaction is used as an exchange of cash flows based on a fixed rate for cash flows based on a variable rate. In an interest rate cap agreement, a cash flow is generated if the price or interest rate of an underlying variable rises above a certain threshold price or interest rate. In an interest rate floor agreement, a cash flow is generated if the price or interest rate of an underlying variable falls below a certain threshold price or interest rate. Caps and floors are designed as protection against the interest rate on a variable rate asset or liability rising above or falling below a certain level. At the inception of a derivative contract, the Company designates the derivatives as one of three types based on the Company’s intentions and belief as to likely effectiveness as a hedge. These three types are: (1) a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (“fair value hedge”); (2) a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (“cash flow hedge”); or (3) an instrument with no hedging designation (“stand-alone derivative”). For a fair value hedge, the gain or loss on the derivative, as well as the offsetting loss or gain on the hedged item, are recognized in current earnings as fair value changes. For a cash flow hedge, the gain or loss on the derivative is reported in other comprehensive income and is reclassified into earnings in the same periods during which the hedged transaction affects earnings. For both types of hedges, changes in the fair value of derivatives that are not highly effective in hedging the changes in fair value or expected cash flows of the hedged item are recognized immediately in current earnings. Changes in the fair value of derivatives that do not qualify for hedge accounting are reported currently in earnings as non-interest income. Net cash settlements on derivatives that qualify for hedge accounting are recorded in interest income or interest expense, based on the item being hedged. Net cash settlements on derivatives that do not qualify for hedge accounting are reported in non-interest income. Cash flows on hedges are classified in the cash flow statement the same as the cash flows of the items being hedged unless the derivative meets the criteria to be a financing derivative. All derivatives are recognized in the consolidated balance sheet at their fair values and are reported as either derivative assets or derivative liabilities net of accrued net settlements and collateral, if any. The individual derivative amounts are netted by counterparty when the netting requirements have been met. If these netted values are positive, they are classified as an asset and, if negative, they are classified as a liability. The Company formally documents the relationship between derivatives and hedged items, as well as the risk-management objective and the strategy for undertaking hedge transactions at the inception of the hedging relationship. This documentation includes linking fair value or cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, at least quarterly, whether the derivative instruments that are used are highly effective in offsetting changes in fair values or cash flows of the hedged items. The Company discontinues hedge accounting when it determines that the derivative is no longer effective in offsetting changes in the fair value or cash flows of the hedged item, the derivative is settled or terminates, a hedged forecasted transaction is no longer probable, a hedged firm commitment is no longer firm or treatment of the derivative as a hedge is no longer appropriate or intended. When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded as non-interest income. When a fair value hedge is discontinued, the hedged asset or liability is no longer adjusted for changes in fair value and the existing basis adjustment is amortized or accreted over the remaining life of the asset or liability. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transactions are still expected to occur, gains or losses that are accumulated in other comprehensive income are amortized into earnings over the same periods which the hedged transactions will affect earnings. The Company has entered into interest rate cap derivatives to assist with interest rate risk management. These derivatives are not designated as hedging instruments but rather as stand-alone derivatives. The fair values of stand-alone derivatives are included in other assets and other liabilities. Changes in fair value of stand-alone derivatives are recorded through earnings as non-interest income.
Income Taxes	Income Taxes On December 22, 2017, the President of the United States signed the 2017 Tax Cuts and Jobs Act (Tax Reform) which reduced the U.S. federal statutory corporate income tax rate from 35% to 21% beginning in 2018. In connection with the December 2017, enactment the Company recognized a $1,086 re-measurement of its net deferred tax assets, including a re-measurement of $535 in a net deferred tax asset related to unrealized losses on available-for-sale securities and held-to-maturity securities previously transferred from available-for-sale. Because the tax effect of variations in unrealized losses on available-for-sale securities and transferred held-to-maturity securities impact accumulated other comprehensive income, the Company had a stranded tax effect of $535 as of the date of enactment. The Company elected to early adopt ASU 2018-02 resulting in a reclassification of $535 from accumulated other comprehensive income to retained earnings in December 2017. The Company recognizes interest and/or penalties related to income tax matters in income tax expense. There were no such interest or penalties incurred in 2019, 2018 or 2017.

Revenue Recognition	The majority of the Company’s revenues come from interest income on financial instruments, including loans, leases, securities and derivatives, which are outside the scope of ASC 606. The Company’s services that fall within the scope of ASC 606 are presented with non-interest income and are recognized as revenue as the Company satisfies its obligation to the customer. Services within the scope of ASC 606 include service charges and fees on deposits, debit card income, investment referral income, insurance sales commissions and other non-interest income related to loans and deposits. Except for gains or losses from the sale of other real estate owned, all of the Company’s revenue from contracts with customers within the scope of ASC 606 is recognized in non-interest income. The following table presents the Company’s sources of non-interest income for the years ended December 31, 2019, and 2018. 2019 2018 Non-interest income Service charges and fees $ 8,672 $ 7,250 Debit card income 8,230 6,178 Mortgage banking (a) 2,468 1,298 Increase in bank-owned life insurance (a) 1,998 2,199 Net gain (loss) from securities transactions (a) 14 (9 ) Other Investment referral income 590 395 Trust income 243 81 Insurance sales commissions 177 245 Recovery on zero-basis purchased loans (a) 143 420 Income from equity method investments (a) 26 7 Other non-interest income related to loans and deposits 2,340 1,612 Other non-interest income not related to loans and deposits(a) 87 49 Total other non-interest income 3,606 2,809 Total $ 24,988 $ 19,725 (a) A description of the Company’s revenue streams accounted for under ASC 606 follows. Service Charges and Fees The company earns fees from its deposit customers for transaction-based, account maintenance and overdraft services. Transaction-based fees, which include services such as stop payment charges, statement rendering and ACH fees, are recognized at the time the transaction is executed as that is the point in time the Company fulfills the customer’s request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which the Company satisfies the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are collected through withdrawal from the customer’s account balance. Debit Card Income The Company earns debit card income from cardholder transactions conducted through payment processors. Debit card income from cardholder transactions represent a percentage of the underlying transaction value and are recognized concurrently with the transaction processing services provided to the cardholder. Investment Referral Income Investment referral services are offered through an unaffiliated registered broker-dealer and investment advisor. Investment referral income consists of transaction-based fees (i.e., trade commissions) and account fees (i.e., custodial fees). The service obligation for transaction-based fees relates to processing of individual transactions and is considered earned at the time the transaction occurs. The Company currently records this income when payment is received and at each month end for current-month transactions. Account fees are considered earned over the period for which the fees relate. These fees are received during the first month of each quarter and represent advance payment for the current quarter. These fees are amortized ratably over the three months during the quarter. Therefore, all account-based fees are currently recorded as performance obligations are satisfied. Trust Income Trust income includes fees from asset management, custody, recordkeeping, investment advisory and administration services. Revenue is recognized at the time the services are performed and may be based on either the fair value of the account or the services provided. Insurance Sales Commissions Insurance commissions are received based on contracts with insurance companies which provide for a percentage of premiums to be paid to the Company in exchange for placement of policies with customers. The commissions generally relate to a period of one year or less. Under certain contracts, the Company may also assist with the claims processing, but this performance obligation is considered insignificant compared to the initial placement of the policy. As such, the performance obligation is considered to have been substantially satisfied at the time of policy placement. While this indicates that all related revenue would be appropriately accrued at policy inception, in some cases recognition occurs over the policy period if received in installments from the insurance company. In no cases would this deferral extend beyond 12 months and the effect is considered immaterial compared to recognition at the time of policy placement. The Company also receives commissions based on renewals of policies previously placed. However, additional work is required to process the renewals, resulting in future performance obligations to earn the related revenues. In addition, the occurrence of such renewals is not certain as initial policies are generally for one year or less and the fees earned are not determined until the time of renewal, based on underwriting at that time. As such, the Company has determined that accrual of income for future renewals is not appropriate. Other non-interest Income Other non-interest income related to loans and deposits is earned when the specific transaction is processed, similar to service charges and fees. Gain of Loss on Sale of Other Real Estate Gain or loss on sale of other real estate is reported in non-interest expense and is netted with other real estate expenses. The Company records a gain or loss from the sale of other real estate when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. When the Company finances the sale of other real estate to the buyer, the Company assesses whether the buyer is committed to perform their obligation under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the other real estate is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on the sale, the Company adjusts the transaction price and related gain or loss on sale if a significant financing component is present. As a result, the Company has concluded that ASC 606 will affect the decision to recognize or defer gains on sales of other real estate in circumstances where the Company has financed the sale.
