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 in Kansas and Missouri. 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 method 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. Loans Held for Sale Loans Purchased Credit Impaired Loans. Nonaccrual Loans Impaired Loans 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 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 2015 and 2014. 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. 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 effect 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 The Company recognizes interest and/or penalties related to income tax matters in income tax expense. No such interest or penalties were incurred in 2015, 2014 or 2013. 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. This compensation expense is recognized ratably over the service period stipulated in the grant agreement.

Business Combination and Branch Sales	NOTE 2 – BUSINESS COMBINATION AND BRANCH SALES Business Combination On October 9, 2015, the Company acquired 100% of the outstanding common shares of First Independence Corporation and its subsidiary, First Federal Savings & Loan of Independence, based in Independence, Kansas, collectively referred to as “First Independence”. Results of operations of First Independence were included in the Company’s results of operations beginning October 10, 2015. Acquisition-related costs of $1,691 are included in merger expenses in the Company’s income statement for the year ended December 31, 2015. All information necessary to recognize the fair value of assets acquired and liabilities assumed has been received. The recognized amounts of the identifiable net assets acquired, including deferred tax assets associated with NOL and tax credit carryforwards, exceeded the cash consideration exchanged resulting in a gain on acquisition of $682. The acquisition was an expansion into southeast Kansas with the addition of four branch locations, and the Company believes it will be able to achieve cost savings by integrating the two companies and combining accounting, data processing and other administrative costs. The following table summarizes the consideration paid for First Independence and the amounts of the assets acquired and liabilities assumed recognized at the acquisition date: Fair value of consideration: Cash $ 14,741 Recognized amounts of identifiable assets acquired and liabilities assumed: Cash and due from banks $ 5,695 Available-for-sale securities 29,355 Federal Reserve Bank and Federal Home Loan Bank stock 1,419 Loans 89,901 Premises and equipment 1,163 Core deposit intangible 717 Other real estate owned 115 Deferred tax asset, net 2,535 Interest receivable 197 Other assets 3,939 Total assets acquired 135,036 Deposits 87,096 Federal Home Loan Bank advances 31,603 Interest payable and other liabilities 914 Total liabilities assumed 119,613 Total identifiable net assets 15,423 Gain on acquisition (682 ) $ 14,741 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 additional information about the loans acquired in the First Independence acquisition as of the date of acquisition: Non-Credit Purchase Credit Contractually required principal $ 88,848 $ 2,146 Non-accretable difference (expected losses) — (506 ) Cash flows expected to be collected 88,848 1,640 Accretable yield (587 ) — Fair value of acquired loans $ 88,261 $ 1,640 The following table presents the carrying value of the loans acquired in the First Independence acquisition by class, as of the date of acquisition: Non-Credit Purchased Credit Impaired Total Commercial real estate $ 12,300 $ 718 $ 13,018 Commercial and industrial 425 — 425 Residential real estate 70,368 891 71,259 Agricultural real estate — — — Consumer 4,994 31 5,025 Agricultural 174 — 174 Fair value of acquired loans $ 88,261 $ 1,640 $ 89,901 In connection with the acquisition of First Independence, the Company acquired servicing rights related to $6,317 of residential real estate loans. Residential real estate loans serviced for others are not reported as assets. These loans were sold by First Independence with servicing rights retained and with limited recourse. The Company recorded a mortgage servicing asset of $29 in other assets and a reserve for losses of $77 in other liabilities in conjunction with these serviced residential real estate loans. The acquisition is not significant to the overall income of the Company; therefore, no pro forma information has been included. The operations of First Independence were merged into the Company as of the date of the acquisition. Separate revenue and earnings of the former First Independence are not available subsequent to the business combination. Branch Sales On November 7, 2014, the Company sold two branches located in Spring Hill, Kansas and De Soto, Kansas to an unaffiliated institution. As a result of the sale of these branches, the Company transferred deposits, including accrued interest, of $17,014. Bank premises and equipment of $3,085 were sold at recorded value. A loss of $20 was recognized on the sale of these branches, and is included in other non-interest expense in the Company’s income statement for the year ended December 31, 2014.

The fair value and amortized cost of debt securities at December 31, 2015, by contractual maturity, is shown below. Expected maturities will differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties. Securities not due at a single maturity date, primarily mortgage-backed securities, are shown separately.

At year-end 2015 and 2014, there were no holdings of securities of any one issuer, other than the U.S. Government and its agencies, in an amount greater than 10% of stockholders’ equity. The following tables show gross unrealized losses and fair value, aggregated by investment category, and length of time that individual securities have been in a continuous unrealized loss position at December 31, 2015 and 2014: Less Than 12 Months 12 Months or More Total Fair Unrealized Fair Unrealized Fair Unrealized December 31, 2015 Available-for-sale securities U.S. Government-sponsored entities $ 9,923 $ (77 ) $ — $ — $ 9,923 $ (77 ) Residential mortgage-backed (issued by government-sponsored entities) 89,235 (497 ) — — 89,235 (497 ) Corporate 2,954 (46 ) — — 2,954 (46 ) Equity securities — — 494 (6 ) 494 (6 ) Total temporarily impaired securities $ 102,112 $ (620 ) $ 494 $ (6 ) $ 102,606 $ (626 ) December 31, 2014 Available-for-sale securities U.S. Government-sponsored entities $ 6,777 $ (162 ) $ — $ — $ 6,777 $ (162 ) Residential mortgage-backed (issued by government-sponsored entities) 2,499 (18 ) — — 2,499 (18 ) Equity securities — — 496 (4 ) 496 (4 ) Total temporarily impaired securities $ 9,276 $ (180 ) $ 496 $ (4 ) $ 9,772 $ (184 ) Less Than 12 Months 12 Months or More Total Fair Unrealized Fair Unrealized Fair Unrealized December 31, 2015 Held-to-maturity securities U.S. Government-sponsored entities $ 2,643 $ (26 ) $ — $ — $ 2,643 $ (26 ) Residential mortgage-backed (issued by government-sponsored entities) 99,181 (1,077 ) 87,992 (1,629 ) 187,173 (2,706 ) Corporate 5,505 (12 ) 7,253 (360 ) 12,758 (372 ) Small Business Administration loan pools 1,315 (5 ) 1,560 (40 ) 2,875 (45 ) State and political subdivisions 3,180 (29 ) 6,300 (77 ) 9,480 (106 ) Total temporarily impaired securities $ 111,824 $ (1,149 ) $ 103,105 $ (2,106 ) $ 214,929 $ (3,255 ) December 31, 2014 Held-to-maturity securities Residential mortgage-backed (issued by government-sponsored entities) $ 18,093 $ (30 ) $ 121,617 $ (1,480 ) $ 139,710 $ (1,510 ) Corporate 4,296 (141 ) 8,483 (231 ) 12,779 (372 ) Small Business Administration loan pools — — 1,720 (58 ) 1,720 (58 ) State and political subdivisions 1,930 (11 ) 15,160 (351 ) 17,090 (362 ) Total temporarily impaired securities $ 24,319 $ (182 ) $ 146,980 $ (2,120 ) $ 171,299 $ (2,302 ) As of December 31, 2015, the Company held 24 available-for-sale securities and 101 held-to-maturity securities in an unrealized loss position. The tables above present unrealized losses on held-to-maturity securities since the date of the securities purchases, 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: 2015 2014 2013 Proceeds $ 17,105 $ 36,627 $ 14,356 Gross gains 370 986 504 Gross losses — — (4 ) Income tax expense on net realized gains 142 377 187 Included in net gains on sales of and settlement of securities in the Company’s consolidated statement of income for 2015 is $386 received in connection with the bankruptcy settlement related to a political subdivision security written off in 2011. During 2014, the Company reclassified securities with a carrying value of $6,188 from held-to-maturity to available-for-sale. This reclassification was the result of the Basel III final rules regarding regulatory capital, effective January 1, 2015, which restrict the amount of certain investments the Company may own. Because of the change in the capital treatment under Basel III, the reclassification was allowed without requiring the remainder of the held-to-maturity portfolio to be reclassified to available-for-sale. At the time the securities were reclassified, they were immediately sold, with a recognized gain on sale of $149.

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, 2015, the portfolio of interest rate swaps had a weighted average maturity of 10.0 years, a weighted average pay rate of 4.45% and a weighted average rate received of 2.37%. No interest rate swaps were outstanding at December 31, 2014. Stand-Alone Derivatives: 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. At December 31, 2015, the interest rate cap had a term of 3.9 years and a cap rate of 4.50%. At December 31, 2014, the interest rate cap had a term of 4.9 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 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 Kansas, Missouri, 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 $9,121 that expire between 2016 and 2026 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 the acquisition of First Independence, the Company acquired Kansas net operating losses useable against Kansas bank income. At December 31, 2015, the Kansas net operating loss carryforward useable against Kansas bank income totaled $3,891 with expiration dates between 2019 and 2022. 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 2012. At December 31, 2015 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 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 by January 1, 2019. The net unrealized gain or loss on available-for-sale securities is not included in computing regulatory capital. Capital amounts and rations for December 31, 2014 are calculated using Basel I rules. Management believes as of December 31, 2015, 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, 2015, 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, 2015 and 2014 are presented in the tables below. Ratios provided for Equity Bancshares, Inc. represent the ratios of the Company on a consolidated basis.

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 $18 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 2015, 2014 and 2013 were $414, $341 and $302. 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 multiemployer 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 multiemployer 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 59 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, 2014. 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): 2015 Net pension cost charged to salaries and employee benefits $ 16 Pentegra defined benefit plan funded status as of July 1 109.41 % First Independence’s funded status as of July 1 100.93 % Contributions paid to the plan $ 50 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, 2015.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-Based Payments	NOTE 19 - SHARE-BASED PAYMENTS The Company’s 2013 Stock Incentive Plan (the Plan) permits the grant of non-qualified stock options and shares to its employees and directors for up to 725,000 shares of common stock. The Plan replaced the 2006 Non-qualified Stock Option Plan (2006 Plan). Under the 2006 Plan there were 205,700 fully vested and exercisable options outstanding at December 31, 2015 and 2014. 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 director compensation policy, directors may elect to receive all or a portion of their fees in cash, Company stock, or non-qualified stock options. During the year ended December 31, 2014 the Company recognized directors compensation expense of $37 and issued 2,568 shares of Company stock pursuant to certain directors’ elections under the Company’s director compensation policy. There were no directors’ elections for payment of director compensation in Company stock in the years ended December 31, 2015 and 2013. Stock Option Awards The following tables summarize stock option activity for the years ended December 31, 2015 and 2014: December 31, 2015 Options Weighted Average Exercise Price Weighted Average Remaining Contractual Term Aggregate Intrinsic Value Outstanding at beginning of year 390,856 $ 13.55 8 $ 428 Granted 173,889 21.25 10 — Exercised — — — — Forfeited or expired (2,750 ) (14.25 ) (10 ) — Outstanding at end of year 561,995 15.93 8 4,194 Fully vested and expected to vest 561,995 15.93 8 4,194 Exercisable at end of year 351,700 14.79 7 3,024 December 31, 2014 Options Weighted Average Exercise Price Weighted Average Remaining Contractual Term Aggregate Intrinsic Value Outstanding at beginning of year 247,889 $ 13.29 7 $ 150 Granted 142,967 13.99 10 — Exercised — — — — Forfeited or expired — — — — Outstanding at end of year 390,856 13.55 8 428 Fully vested and expected to vest 390,856 13.55 8 428 Exercisable at end of year 231,606 13.94 7 225 The fair values of stock options granted during the years ended December 31, 2015, 2014 and 2013 were estimated to be $5.39 per share, $3.58 per share and $3.20 per share. The fair value of each option award is estimated on the date of grant using a closed form option valuation (Black-Scholes) model. Expected stock price volatility is based on the historical volatility of the SNL Bank Index. The expected term of options granted is based on the Simplified Method. The risk-free interest rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. The fair values of options granted were determined using the following weighted-average assumptions as of grant dates. 2015 2014 2013 Risk free rate 1.92 % 1.84 % 1.72 % Market value of stock on grant date $ 21.25 $ 13.99 $ 13.00 Expected term (in years) 5.8 5.7 5.0 Expected volatility 21.49 % 22.50 % 23.93 % Dividend rate — % — % — % Compensation expense for stock options is recognized as the options vest. Total stock option compensation cost that has been charged against income was $397, $445, and $233 for 2015, 2014, and 2013. The total income tax benefit was $152, $170 and $89. At December 31, 2015 there was $886 of unrecognized compensation expense related to non-vested stock options granted under the Plan. Unrecognized compensation expense at December 31, 2015 will be recognized over a remaining weighted average period of 4 years. Remaining options available to be granted under the Plan were 336,062 at December 31, 2015. Restricted Stock Unit Plan The Company’s Restricted Stock Unit Plan (RSUP), which was terminated May 22, 2014, provided for the issuance of restricted stock units (“RSUs”) to certain directors and officers. Prior to termination, RSUs vested over a five-year period subject to completion of service; however, no shares vested in the first two years following the RSU issuance. To the extent vested, the RSUs became Class A voting common stock on the later of the fifth anniversary of the issuance date of the RSU or at separation of service. Compensation expense was recognized over the vesting period of the awards based on the estimated fair value of the RSUs at issuance dates. Upon the 2014 termination of the RSUP, the vesting of 183,472 RSUs outstanding was accelerated and the issuance of Class A voting common stock was authorized to take place on the first business day following the first anniversary of the RSUP termination. In addition, the service period was shortened and the remaining unrecognized compensation was expensed in 2014. The Company recognized stock based compensation expense attributable to the RSUP of $0, $1,524 and $303 for the years ended December 31, 2015, 2014 and 2013. The total income tax benefit was $0, $590 and $113. As of December 31, 2015, there was $0 unrecognized compensation cost related to non-vested shares granted under the RSUP.

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 securities available-for-sale 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, including U.S. Government sponsored agencies, residential mortgage-backed securities (all of which are issued or guaranteed by government sponsored agencies), corporate securities, Small Business Administration securities, State and Political Subdivision securities, and equity securities 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, 2015 (Level 1) (Level 2) (Level 3) Assets: Available-for-sale securities: U.S. government-sponsored entities $ — $ 17,036 $ — Residential mortgage-backed securities (issued by government-sponsored entities) — 109,521 — Corporate — 2,954 — Small Business Administration loan pools — 297 — State and political subdivisions — 508 — Equity securities — 494 — Derivative assets (included in other assets) — 2 — Cash collateral held by counterparty 24 — — Total derivative assets 24 2 — Total assets 24 130,812 — Liabilities: Derivative liabilities (included in other liabilities) — 246 — Cash collateral held by counterparty (246 ) — — Total derivative liabilities (246 ) 246 — Total liabilities (246 ) 246 — December 31, 2014 (Level 1) (Level 2) (Level 3) Assets: Available-for-sale securities: U.S. government-sponsored entities $ — $ 10,400 $ — Residential mortgage-backed securities (issued by government-sponsored entities) — 36,529 — Corporate — 3,011 — Small Business Administration loan pools — 356 — State and political subdivisions — 2,193 — Equity securities — 496 — Derivative assets (included in other assets) — 11 — Total assets $ — $ 52,996 $ — There were no transfers between Levels during 2015 or 2014. 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, 2015 (Level 1) (Level 2) (Level 3) Impaired loans: Commercial real estate $ — $ — $ 2,986 Commercial and industrial — — 57 Residential real estate — — 594 Other — — 65 Other real estate owned: Commercial real estate — — 524 Residential real estate — — 387 December 31, 2014 (Level 1) (Level 2) (Level 3) Impaired loans: Commercial real estate $ — $ — $ 4,386 Commercial and industrial — — 663 Residential real estate — — 801 Other — — 158 Other real estate owned: Commercial real estate — — 524 Residential real estate — — 646 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, 2015 and 2014. 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. Appraisals may include the utilization of unobservable inputs, subjective factors, and utilize quantitative data to estimate fair market value. The following table presents additional information about the unobservable inputs used in the fair value measurement of financial assets measured on a nonrecurring basis that were categorized with Level 3 of the fair value hierarchy: Fair Valuation Technique Unobservable Input Range (weighted December 31, 2015 Impaired loans $ 3,702 Sales Comparison Approach Adjustments for differences 7% - 29% December 31, 2014 Impaired loans $ 6,008 Sales Comparison Approach Adjustments for differences 3% - 15% Measurable inputs for other real estate owned are not material.

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. The contractual amounts of commitments to originate loans and available lines of credit as of December 31, 2015 and 2014 were as follows: December 31, 2015 December 31, 2014 Fixed Rate Variable Rate Fixed Rate Variable Rate Commitments to make loans $ 30,261 $ 55,694 $ 9,791 $ 15,776 Mortgage loans in the process of origination 5,116 1,941 2,175 761 Unused lines of credit 44,392 55,769 32,447 48,290 The fixed rate loan commitments have interest rates ranging from 2.15% to 8.50% and maturities ranging from 6 months to 24 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, 2015 and 2014 were as follows: December 31, 2015 December 31, 2014 Fixed Rate Variable Rate Fixed Rate Variable Rate Standby letters of credit $ 3,588 $ 1,253 $ 2,093 $ 616

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 . Equity Bank is a party to a February 3, 2015 lawsuit filed against it by CitiMortgage, Inc. 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. At this stage of the litigation it is difficult to estimate any potential loss, however Equity Bank believes it has numerous and meritorious defenses to the claims and anticipates contesting the matter vigorously. At December 31, 2014, Equity Bank and U.S. Bank (“USB”) were parties to lawsuits filed against each other. These lawsuits involved loan-repurchase demands made by USB and allegations by Equity Bank that USB withheld servicing release premiums (profits) on loans sold by Equity Bank to USB, and also that USB had interfered with a 2012 business combination. In June 2015, Equity Bank and USB settled the lawsuits filed against each other. 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. The Company currently does not believe that it is probable that these matters will result in a material unfavorable outcome for the Company. An estimate of the potential losses from these matters cannot be made at this time as the Company intends to vigorously defend these matters and believes it has meritorious defenses to these potential claims.

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 in Kansas and Missouri. 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 method 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.
Loans Held for Sale	Loans Held for Sale
Loans	Loans Purchased Credit Impaired Loans. Nonaccrual Loans Impaired Loans 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
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 2015 and 2014.

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 effect 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.
