The fair value and amortized cost of debt securities at March 31, 2016, by contractual maturity, is shown below.

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: Three Months Ended March 31, 2016 2015 Proceeds $ 20,459 $ 17,105 Gross gains 420 368 Gross losses — — Income tax expense on net realized gains 161 141

As of March 31, 2016 and December 31, 2015, the Company had balances of $2,605 and $18,852 in mortgage finance loans classified as commercial and industrial. From time to time the Company has purchased pools of residential real estate loans originated by other financial institutions to hold for investment with the intent to diversify the residential real estate portfolio.

The Company analyzes loans individually by classifying the loans as to credit risk. Consumer loans are considered pass 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: Special Mention Substandard: Doubtful: The risk category of loans by class of loans is as follows as of March 31, 2016 and December 31, 2015: March 31, 2016 Pass Special Substandard Doubtful Total Commercial real estate $ 388,722 $ — $ 8,779 $ — $ 397,501 Commercial and industrial 246,078 — 1,019 — 247,097 Residential real estate 241,198 — 2,529 — 243,727 Agricultural real estate 15,636 — 1,113 — 16,749 Consumer 17,299 — 188 — 17,487 Agricultural 15,397 — 97 — 15,494 Total $ 924,330 $ — $ 13,725 $ — $ 938,055 December 31, 2015 Pass Special Substandard Doubtful Total Commercial real estate $ 386,917 $ — $ 10,100 $ — $ 397,017 Commercial and industrial 260,669 — 1,363 — 262,032 Residential real estate 246,901 — 3,315 — 250,216 Agricultural real estate 17,810 — 370 — 18,180 Consumer 17,000 — 103 — 17,103 Agricultural 15,707 — 100 — 15,807 Total $ 945,004 $ — $ 15,351 $ — $ 960,355 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.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	NOTE 4 – DERIVATIVE FINANCIAL INSTRUMENTS The Company is exposed to interest-rate risk primarily from the effect of interest rate changes on its interest-earning assets and its sources of funding these assets. The Company will periodically enter into interest rate swaps or interest rate caps/floors to manage certain interest rate risk exposure. 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 March 31, 2016, the portfolio of interest rate swaps had a weighted average maturity of 8.2 years, a weighted average pay rate of 3.82% and a weighted average rate received of 2.94%. 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%. 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 March 31, 2016, the interest rate cap had a term of 3.7 years and a cap rate of 4.50%. At December 31, 2015, the interest rate cap had a term of 3.9 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 March 31, 2016 and December 31, 2015: March 31, 2016 December 31, 2015 Notional Derivative Derivative Notional Derivative Derivative Derivatives designated as hedging instruments: Interest rate swaps $ 21,242 $ — $ 774 $ 12,284 $ — $ 246 Total derivatives designated as hedging relationships 21,242 — 774 12,284 — 246 Derivatives not designated as hedging instruments: Interest rate caps/floors 3,072 1 — 3,140 2 — Total derivatives not designated as hedging instruments 3,072 1 — 3,140 2 — Total $ 24,314 1 774 $ 15,424 2 246 Cash collateral — (610 ) — (270 ) Netting adjustments — — 24 24 Net amount presented in Balance Sheet $ 1 $ 164 $ 26 $ — For the three-month periods ended March 31, 2016 and 2015, the Company recorded net losses on derivatives and hedging activities: March 31, March 31, Derivatives designated as hedging instruments: Interest rate swaps $ — $ — Total net gain (loss) related to fair value hedge ineffectiveness — — Derivatives not designated as hedging instruments: Economic hedges: Interest rate caps/floors (1 ) (5 ) Total net gains (losses) related to derivatives not designated as hedging instruments (1 ) (5 ) Net gains (losses) on derivatives and hedging activities $ (1 ) $ (5 ) The following table shows the recorded net gains (losses) on derivatives and the related hedged items in fair value hedging relationships and the impact of those derivatives on the Company’s net interest income for the three-month period ended March 31, 2016.

Banking and Thrift [Abstract]
Regulatory Matters	NOTE 7 – 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 and Equity Bank 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. Beginning in January 2016, the implementation of the capital conservation buffer was effective for the Company and Equity Bank starting at the 0.625% level and increasing 0.625% each year thereafter, until it reaches 2.5% on January 1, 2019. The capital conservation buffer is designed to absorb losses during periods of economic stress and requires increased capital levels for the purpose of capital distributions and other payments. Failure to meet the full amount of the buffer will result in restrictions on the Company’s ability to make capital distributions, including dividend payments and stock repurchases, and to pay discretionary bonuses to executive officers. Management believes as of March 31, 2016 and December 31, 2015, that the Company and Equity Bank meet all capital adequacy requirements to which they are subject, including the capital conservation buffer requirement. 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 March 31, 2016, 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.

Fair Value Disclosures [Abstract]
Fair Value	NOTE 9 – 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 interest rate derivative. Cash collateral received from or delivered to a derivative counterparty is classified as Level 1. Assets and liabilities measured at fair value on a recurring basis are summarized below: March 31, 2016 (Level 1) (Level 2) (Level 3) Assets: Available-for-sale securities: U.S. government-sponsored entities $ — $ 12,078 $ — Residential mortgage-backed securities (issued by government-sponsored entities) — 97,523 — Corporate — 2,940 — Small Business Administration loan pools — 271 — State and political subdivisions — 509 — Equity securities 500 — — Derivative assets: Derivative assets (included in other assets) — 1 — Total derivative assets — 1 — Total assets $ 500 $ 113,322 $ — Liabilities: Derivative liabilities: Interest rate swaps (included in other liabilities) $ — $ 774 $ — Cash collateral held by counterparty (610 ) — — Total derivative liabilities (610 ) 774 — Total liabilities $ (610 ) $ 774 $ — 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: 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: Interest rate swaps (included in other liabilities) $ — $ 246 $ — Cash collateral held by counterparty (246 ) — — Total derivative liabilities (246 ) 246 — Total liabilities $ (246 ) $ 246 $ — There were no material transfers between Levels during the three months ended March 31, 2016 or the year ended December 31, 2015. 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 less estimated cost to sell. 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: March 31, 2016 (Level 1) (Level 2) (Level 3) Impaired loans: Commercial real estate $ — $ — $ 2,566 Commercial and industrial — — 108 Residential real estate — — 604 Other — — 227 Other real estate owned: Commercial real estate — — 524 Residential real estate — — 234 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 The Company did not record any liabilities for which the fair value was measured on a non-recurring basis at March 31, 2016 or at December 31, 2015. Valuations of impaired loans and other real estate owned utilize third party appraisals or broker price opinions, and were 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 Value Valuation Technique Unobservable Input Range (weighted average) March 31, 2016 Impaired loans $ 3,505 Sales Comparison Approach Adjustments for 6% -23% (17%) December 31, 2015 Impaired loans $ 3,702 Sales Comparison Approach Adjustments for 7% - 29% (18%) Measurable inputs for other real estate owned were not material.

Legal Matters	NOTE 11 – 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 contingency has 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. 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. The Company currently does not believe that it is probable that this legal matter will result in an unfavorable outcome for the Company or Equity Bank. Except for the above mentioned lawsuit, there are no other outstanding 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.
