Disclosure Text Block [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	NOTE 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations and Principles of Consolidation Simmons First National Corporation (the “Company”) is primarily engaged in providing a full range of banking services to individual and corporate customers through its subsidiaries and their branch banks with offices in Arkansas, Kansas, Missouri and Tennessee. The Company is subject to competition from other financial institutions. The Company also is subject to the regulation of certain federal and state agencies and undergoes periodic examinations by those regulatory authorities. The consolidated financial statements include the accounts of Simmons First National Corporation and its subsidiaries. Significant intercompany accounts and transactions have been eliminated in consolidation. Operating Segments The Company is organized on a regional basis upon which management makes decisions regarding how to allocate resources and assess performance. Each of the regions provides a group of similar community banking services, including such products and services as loans; time deposits, checking and savings accounts; personal and corporate trust services; credit cards; investment management; insurance; and securities and investment services. Loan products include consumer, real estate, commercial, agricultural, equipment and SBA lending. The individual bank regions have similar operating and economic characteristics and have been reported as one aggregated operating segment. The Company also considers its trust, investment and insurance services to be operating segments. Information on these segments is not reported separately since they do not meet the quantitative thresholds under ASC Topic 280-10-50-12. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses, the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans and the valuation of covered loans and related indemnification asset. In connection with the determination of the allowance for loan losses and the valuation of foreclosed assets, management obtains independent appraisals for significant properties. Reclassifications Various items within the accompanying consolidated financial statements for previous years have been reclassified to provide more comparative information. These reclassifications had no effect on net earnings. Cash Equivalents The Company considers all liquid investments with original maturities of three months or less to be cash equivalents. For purposes of the consolidated statements of cash flows, cash and cash equivalents are considered to include cash and non-interest bearing balances due from banks, interest bearing balances due from banks and federal funds sold and securities purchased under agreements to resell. Investment Securities Held-to-maturity securities, which include any security for which the Company has the positive intent and ability to hold until maturity, are carried at historical cost adjusted for amortization of premiums and accretion of discounts. Premiums and discounts are amortized and accreted, respectively, to interest income using the constant yield method over the period to maturity. Available-for-sale securities, which include any security for which the Company has no immediate plan to sell but which may be sold in the future, are carried at fair value. Realized gains and losses, based on specifically identified amortized cost of the individual security, are included in other income. Unrealized gains and losses are recorded, net of related income tax effects, in stockholders' equity. Premiums and discounts are amortized and accreted, respectively, to interest income using the constant yield method over the period to maturity. Trading securities, which include any security held primarily for near-term sale, are carried at fair value. Gains and losses on trading securities are included in other income. The Company applies accounting guidance related to recognition and presentation of other-than-temporary impairment under ASC Topic 320-10. When the Company does not intend to sell a debt security, and it is more likely than not, the Company will not have to sell the security before recovery of its cost basis, it recognizes the credit component of an other-than-temporary impairment of a debt security in earnings and the remaining portion in other comprehensive income. For held-to-maturity debt securities, the amount of an other-than-temporary impairment recorded in other comprehensive income for the noncredit portion of a previous other-than-temporary impairment is amortized prospectively over the remaining life of the security on the basis of the timing of future estimated cash flows of the security. As a result of this guidance, the Company’s consolidated statements of income reflect the full impairment (that is, the difference between the security’s amortized cost basis and fair value) on debt securities that the Company intends to sell or would more likely than not be required to sell before the expected recovery of the amortized cost basis. For available-for-sale and held-to-maturity debt securities that management has no intent to sell and believes that it more likely than not will not be required to sell prior to recovery, only the credit loss component of the impairment is recognized in earnings, while the noncredit loss is recognized in accumulated other comprehensive income. The credit loss component recognized in earnings is identified as the amount of principal cash flows not expected to be received over the remaining term of the security as projected based on cash flow projections. Mortgage Loans Held For Sale Mortgage loans held for sale are carried at the lower of cost or fair value, determined using an aggregate basis. Write-downs to fair value are recognized as a charge to earnings at the time the decline in value occurs. Forward commitments to sell mortgage loans are acquired to reduce market risk on mortgage loans in the process of origination and mortgage loans held for sale. The forward commitments acquired by the Company for mortgage loans in process of origination are not mandatory forward commitments. These commitments are structured on a best efforts basis; therefore, the Company is not required to substitute another loan or to buy back the commitment if the original loan does not fund. Typically, the Company delivers the mortgage loans within a few days after the loans are funded. These commitments are derivative instruments and their fair values at December 31, 2015 and 2014 are not material. Gains and losses resulting from sales of mortgage loans are recognized when the respective loans are sold to investors. Gains and losses are determined by the difference between the selling price and the carrying amount of the loans sold, net of discounts collected or paid. Fees received from borrowers to guarantee the funding of mortgage loans held for sale are recognized as income or expense when the loans are sold or when it becomes evident that the commitment will not be used. Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-offs are reported at their outstanding principal adjusted for any loans charged off, the allowance for loan losses and any unamortized deferred fees or costs on originated loans and unamortized premiums or discounts on purchased loans. For loans amortized at cost, interest income is accrued based on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, as well as premiums and discounts, are deferred and amortized as a level yield adjustment over the respective term of the loan. The accrual of interest on loans, except on certain government guaranteed loans, is discontinued at the time the loan is 90 days past due unless the credit is well-secured and in process of collection. Past due status is based on contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged off at an earlier date if collection of principal or interest is considered doubtful. Discounts and premiums on purchased residential real estate loans are amortized to income using the interest method over the remaining period to contractual maturity, adjusted for anticipated prepayments. Discounts and premiums on purchased consumer loans are recognized over the expected lives of the loans using methods that approximate the interest method. For discussion of the Company’s accounting for acquired loans, see Acquisition Accounting, Covered Loans and Related Indemnification Asset later in this section. Allowance for Loan Losses The allowance for loan losses is management’s estimate of probable losses in the loan portfolio. Loan losses are charged against the allowance when management believes the uncollectability of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Allocations to the allowance for loan losses are categorized as either general reserves or specific reserves. The general reserve is calculated monthly based on management’s assessment of several factors such as (1) historical loss experience based on volumes and types, (2) volume and trends in delinquencies and nonaccruals, (3) lending policies and procedures including those for loan losses, collections and recoveries, (4) national, state and local economic trends and conditions, (5) concentrations of credit within the loan portfolio, (6) the experience, ability and depth of lending management and staff and (7) other factors and trends that will affect specific loans and categories of loans. The Company establishes general allocations for each major loan category and risk rating. This category also includes allocations to loans which are collectively evaluated for loss such as credit cards, one-to-four family owner occupied residential real estate loans and other consumer loans. General reserves have been established, based upon the aforementioned factors and allocated to the individual loan categories. Specific reserves are provided on loans that are considered impaired when it is probable that we will not receive all amounts due according to the contractual terms of the loan, including scheduled principal and interest payments. This includes loans that are delinquent 90 days or more, nonaccrual loans and certain other loans identified by management. Certain other loans identified by management consist of performing loans where management expects that the Company will not receive all amounts due according to the contractual terms of the loan, including scheduled principal and interest payments. Specific reserves are accrued for probable losses on specific loans evaluated for impairment for which the basis of each loan, including accrued interest, exceeds the discounted amount of expected future collections of interest and principal or, alternatively, the fair value of loan collateral. Accrual of interest is discontinued and interest accrued and unpaid is removed at the time such amounts are delinquent 90 days unless management is aware of circumstances which warrant continuing the interest accrual. Interest is recognized for nonaccrual loans only upon receipt and only after all principal amounts are current according to the terms of the contract. Management’s evaluation of the allowance for loan losses is inherently subjective as it requires material estimates. The actual amounts of loan losses realized in the near term could differ from the amounts estimated in arriving at the allowance for loan losses reported in the financial statements. Reserve for Unfunded Commitments In addition to the allowance for loan losses, the Company has established a reserve for unfunded commitments, classified in other liabilities. This reserve is maintained at a level sufficient to absorb losses arising from unfunded loan commitments. The adequacy of the reserve for unfunded commitments is determined monthly based on methodology similar to the Company’s methodology for determining the allowance for loan losses. Net adjustments to the reserve for unfunded commitments are included in other non-interest expense. Acquisition Accounting, Acquired Loans The Company accounts for its acquisitions under ASC Topic 805, Business Combinations The Company evaluates loans acquired in accordance with the provisions of ASC Topic 310-20, Nonrefundable Fees and Other Costs Loans and Debt Securities Acquired with Deteriorated Credit Quality For impaired loans accounted for under ASC Topic 310-30, the Company continues to estimate cash flows expected to be collected on these loans. The Company evaluates at each balance sheet date whether the present value of the loans determined using the effective interest rates has decreased significantly and if so, recognize a provision for loan loss in our consolidated statement of income. For any significant increases in cash flows expected to be collected, the Company adjusts the amount of accretable yield recognized on a prospective basis over the remaining life of the loan. Covered Loans and Related Indemnification Asset In September, we entered into an agreement with the FDIC to terminate all loss share agreements which were entered into in 2010 and 2012 in conjunction with the Company’s acquisition of substantially all of the assets (“covered assets”) and assumption of substantially all of the liabilities of four failed banks in FDIC-assisted transactions. Under the early termination, all rights and obligations of the Company and the FDIC under the FDIC loss share agreements, including the clawback provisions and the settlement of loss share and expense reimbursement claims, have been resolved and terminated. Under the terms of the agreement, the FDIC made a net payment of $2,368,000 to the bank as consideration for the early termination of the loss share agreements. The early termination was recorded in the Company’s financial statements by removing the FDIC Indemnification Asset, receivable from FDIC, the FDIC True-up liability and recording a one-time, pre-tax charge of $7,476,000. As a result, the Company reclassified loans previously covered by FDIC loss share to loans acquired, not covered by FDIC loss share. Foreclosed assets previously covered by FDIC loss share were reclassified to foreclosed assets not covered by FDIC loss share. For further discussion of our acquisition and loan accounting, see Note 2, Acquisitions, and Note 5, Loans Acquired. Premises and Equipment Depreciable assets are stated at cost less accumulated depreciation. Depreciation is charged to expense using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are capitalized and amortized by the straight-line method over the terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter. Premises Held for Sale The Company records premises held for sale at the lower of (1) cost less accumulated depreciation or (2) fair value less estimated selling expenses. These assets are assessed for impairment at the time they are reclassified as held for sale and periodically thereafter. Foreclosed Assets Held For Sale Assets acquired by foreclosure or in settlement of debt and held for sale are valued at estimated fair value as of the date of foreclosure, and a related valuation allowance is provided for estimated costs to sell the assets. Management evaluates the value of foreclosed assets held for sale periodically and increases the valuation allowance for any subsequent declines in fair value. Changes in the valuation allowance are charged or credited to other expense. Bank Owned Life Insurance The Company maintains bank-owned life insurance policies on certain current and former employees and directors, which are recorded at their cash surrender values as determined by the insurance carriers. The appreciation in the cash surrender value of the policies is recognized as a component of non-interest income in the Company’s consolidated statements of income. Goodwill and Intangible Assets Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. Other intangible assets represent purchased assets that also lack physical substance but can be separately distinguished from goodwill because of contractual or other legal rights or because the asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset or liability. The Company performs an annual goodwill impairment test, and more frequently if circumstances warrant, in accordance with ASC Topic 350, Intangibles – Goodwill and Other Derivative Financial Instruments The Company may enter into derivative contracts for the purposes of managing exposure to interest rate risk to meet the financing needs of its customers. The Company records all derivatives on the balance sheet at fair value. Historically, the Company’s policy has been not to invest in derivative type investments, but, in an effort to meet the financing needs of its customers, the Company has entered into limited fair value hedges. Fair value hedges include interest rate swap agreements on fixed rate loans. For derivatives designated as hedging the exposure to changes in the fair value of the hedged item, the gain or loss is recognized in earnings in the period of change together with the offsetting loss or gain of the hedging instrument. The fair value hedges are considered to be highly effective and any hedge ineffectiveness was deemed not material. The notional amount of the swaps was $61.3 million at December 31, 2015, and $14.6 million at December 31, 2014. Securities Sold Under Agreements to Repurchase The Company sells securities under agreements to repurchase to meet customer needs for sweep accounts. At the point funds deposited by customers become investable, those funds are used to purchase securities owned by the Company and held in its general account with the designation of Customers’ Securities. A third party maintains control over the securities underlying overnight repurchase agreements. The securities involved in these transactions are generally U.S. Treasury or Federal Agency issues. Securities sold under agreements to repurchase generally mature on the banking day following that on which the investment was initially purchased and are treated as collateralized financing transactions which are recorded at the amounts at which the securities were sold plus accrued interest. Interest rates and maturity dates of the securities involved vary and are not intended to be matched with funds from customers. Bankcard Fee Income Periodic bankcard fees, net of direct origination costs, are recognized as revenue on a straight-line basis over the period the fee entitles the cardholder to use the card. Income Taxes The Company accounts for income taxes in accordance with income tax accounting guidance in ASC Topic 740, Income Taxes Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term more likely than not means a likelihood of more than 50 percent; the terms examined and upon examination also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances and information available at the reporting date and is subject to management’s judgment. Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized. The Company files consolidated income tax returns with its subsidiaries. Earnings Per Share Basic earnings per share are computed based on the weighted average number of shares outstanding during each year. Diluted earnings per share are computed using the weighted average common shares and all potential dilutive common shares outstanding during the period. The computation of per share earnings is as follows: (In thousands, except per share data) 2015 2014 2013 Net income available to common shareholders $ 74,107 $ 35,688 $ 23,231 Average common shares outstanding 28,084 16,879 16,339 Average potential dilutive common shares 126 43 13 Average diluted common shares 28,210 16,922 16,352 Basic earnings per share $ 2.64 $ 2.11 $ 1.42 Diluted earnings per share $ 2.63 $ 2.11 $ 1.42 Stock options to purchase 84,780 shares for the year ended December 31, 2013 were not included in the earnings per share calculation because the exercise price exceeded the average market price. There were no such shares for the years ended December 31, 2015 and 2014. Stock-Based Compensation The Company has adopted various stock-based compensation plans. The plans provide for the grant of incentive stock options, nonqualified stock options, stock appreciation rights and bonus stock awards. Pursuant to the plans, shares are reserved for future issuance by the Company, upon exercise of stock options or awarding of bonus shares granted to directors, officers and other key employees. In accordance with ASC Topic 718, Compensation – Stock Compensation Subsequent Events As part of the acquisition of Community First, the Company issued 30,852 shares of Senior Non-Cumulative Perpetual Preferred Stock, Series A (“Simmons Series A Preferred Stock”). The preferred stock is held by the United States Department of the Treasury (“Treasury”) as the Community First Series C Preferred Stock was issued when Community First entered into a Small Business Lending Fund Securities Purchase Agreement with the Treasury. On January 29, 2016, the Company redeemed all of the preferred stock, including accrued and unpaid dividends. On February 19, 2016, the trust and fiduciary business operations of Simmons First Trust Company, N.A., a wholly-owned subsidiary of Simmons Bank, were merged into Simmons Bank.

Mergers, Acquisitions and Dispositions Disclosures [Text Block]	NOTE 2: ACQUISITIONS Liberty Bancshares, Inc. On February 27, 2015, Simmons First National Corporation completed the acquisition of Liberty Bancshares, Inc. (“Liberty”), headquartered in Springfield, Missouri, including its wholly-owned bank subsidiary Liberty Bank (“LB”). The Company issued 5,181,337 shares of its common stock valued at approximately $212.2 million as of February 27, 2015 in exchange for all outstanding shares of Liberty common stock. Prior to the acquisition, Liberty conducted banking business from 24 branches located in southwest Missouri. Including the effects of the purchase accounting adjustments, the Company acquired approximately $1.1 billion in assets, approximately $780.7 million in loans including loan discounts and approximately $874.7 million in deposits. The Company completed the systems conversion and merged LB into Simmons First National Bank (“Simmons Bank” or the “Bank”) on April 24, 2015. Goodwill of $95.2 million was recorded as a result of the transaction. The merger strengthened the Company’s position in the southwest Missouri market and the Company believes that it will be able to achieve cost savings by integrating the two companies and combining accounting, data processing, and other administrative functions all of which gave rise to the goodwill recorded. The goodwill will not be deductible for tax purposes. A summary, at fair value, of the assets acquired and liabilities assumed in the Liberty transaction, as of the acquisition date, is as follows: (In thousands) Acquired from Fair Value Fair Assets Acquired Cash and due from banks, including time deposits $ 102,637 $ (14 ) $ 102,623 Federal funds sold 7,060 -- 7,060 Investment securities 99,123 (335 ) 98,788 Loans acquired, not covered by FDIC loss share 790,493 (9,835 ) 780,658 Allowance for loan losses (10,422 ) 10,422 -- Premises and equipment 34,239 (3,215 ) 31,024 Bank owned life insurance 16,972 -- 16,972 Core deposit intangible 699 13,857 14,556 Other intangibles 3,063 (3,063 ) -- Other assets 17,703 (3,112 ) 14,591 Total assets acquired $ 1,061,567 $ 4,705 $ 1,066,272 Liabilities Assumed Deposits: Non-interest bearing transaction accounts $ 146,618 $ -- $ 146,618 Interest bearing transaction accounts and savings deposits 543,183 -- 543,183 Time deposits 184,913 -- 184,913 Total deposits 874,714 -- 874,714 FHLB borrowings 46,128 223 46,351 Subordinated debentures 20,620 (510 ) 20,110 Accrued interest and other liabilities 7,828 300 8,128 Total liabilities assumed 949,290 13 949,303 Equity 112,277 (112,277 ) -- Total equity assumed 112,277 (112,277 ) -- Total liabilities and equity assumed $ 1,061,567 $ (112,264 ) $ 949,303 Net assets acquired 116,969 Purchase price 212,176 Goodwill $ 95,207 The following is a description of the methods used to determine the fair values of significant assets and liabilities presented in the Liberty acquisition above.

The Company’s operating results for 2015 include the operating results of the acquired assets and assumed liabilities of Liberty subsequent to the acquisition date. Community First Bancshares, Inc. On February 27, 2015, Simmons First National Corporation completed the acquisition of Community First Bancshares, Inc. (“Community First”), headquartered in Union City, Tennessee, including its wholly-owned bank subsidiary First State Bank (“FSB”). The Company issued 6,552,915 shares of its common stock valued at approximately $268.3 million as of February 27, 2015, plus $9,974 in cash in exchange for all outstanding shares of Community First common stock. The Company also issued $30.9 million of preferred stock in exchange for all outstanding shares of Community First preferred stock. Prior to the acquisition, Community First conducted banking business from 33 branches located across Tennessee. Including the effects of the purchase accounting adjustments, the Company acquired approximately $1.9 billion in assets, approximately $1.1 billion in loans including loan discounts and approximately $1.5 billion in deposits. The Company completed the systems conversion and merged FSB into Simmons Bank on September 4, 2015. Goodwill of $110.4 million was recorded as a result of the transaction. The merger allowed the Company’s entrance into the Tennessee market and will serve as a launching platform for possible expansion into adjacent areas. The Company believes that it will be able to achieve cost savings by integrating the two companies and combining accounting, data processing, and other administrative functions. Further the Company believes it can benefit from the addition of Community First's small-business lending platform while cross-selling its trust products in Community First’s market. This combination of factors gave rise to the goodwill recorded. The goodwill will not be deductible for tax purposes. A summary, at fair value, of the assets acquired and liabilities assumed in the Community First transaction, as of the acquisition date, is as follows: (In thousands) Acquired from Fair Value Fair Assets Acquired Cash and due from banks $ 39,848 $ -- $ 39,848 Federal funds sold 76,508 -- 76,508 Investment securities 570,199 (3,381 ) 566,818 Loans acquired, not covered by FDIC loss share 1,163,398 (26,855 ) 1,136,543 Allowance for loan losses (14,635 ) 14,635 -- Foreclosed assets not covered by FDIC loss share 747 -- 747 Premises and equipment 44,837 (2,794 ) 42,043 Bank owned life insurance 22,149 -- 22,149 Goodwill 100 (100 ) -- Core deposit intangible -- 11,273 11,273 Other intangibles -- 420 420 Deferred tax asset 3,700 3,538 7,238 Other assets 11,474 -- 11,474 Total assets acquired $ 1,918,325 $ (3,264 ) $ 1,915,061 Liabilities Assumed Deposits: Non-interest bearing transaction accounts $ 103,825 $ -- $ 103,825 Interest bearing transaction accounts and savings deposits 995,207 -- 995,207 Time deposits 436,181 849 437,030 Total deposits 1,535,213 849 1,536,062 Federal funds purchased and securities sold under agreement to repurchase 16,230 -- 16,230 FHLB borrowings 143,047 674 143,721 Subordinated debentures 21,754 (840 ) 20,914 Accrued interest and other liabilities 8,769 601 9,370 Total liabilities assumed 1,725,013 1,284 1,726,297 Equity 193,312 (193,312 ) -- Total equity assumed 193,312 (193,312 ) -- Total liabilities and equity assumed $ 1,918,325 $ (192,028 ) $ 1,726,297 Net assets acquired 188,764 Purchase price 299,204 Goodwill $ 110,440 The following is a description of the methods used to determine the fair values of significant assets and liabilities presented in the Community First acquisition above.

Summary of Unaudited Pro forma Information The unaudited pro forma information below for the years ended December 31, 2015 and 2014 gives effect to the Liberty and Community First acquisitions as if the acquisitions had occurred on January 1, 2014. P ro forma earnings for the year ended December 31, 2015 were adjusted to exclude $7.4 million of acquisition-related costs, net of tax, incurred by Simmons during 2015. The pro forma financial information is not necessarily indicative of the results of operations if the acquisitions had been effective as of this date. Years Ended December 31 (In thousands, except per share data) 2015 2014 Revenue (1) $ 395,959 $ 390,606 Net income $ 85,773 $ 64,166 Earnings per share $ 2.68 $ 2.24 (1) Net interest income plus noninterest income. Consolidated year-to-date 2015 results included approximately $46.0 million of revenue and $24.2 million of net income attributable to the Liberty acquisition and $77.3 million of revenue and $33.3 million of net income attributable to the Community First acquisition. Ozark Trust & Investment Corporation On October 29, 2015, Simmons First National Corporation completed the acquisition of Ozark Trust & Investment Corporation (“Ozark Trust”), headquartered in Springfield, Missouri, including its wholly-owned non-deposit trust company, Trust Company of the Ozarks (“TCO”). Simmons issued 339,290 shares of its common stock valued at approximately $17.9 million as of October 29, 2015, plus $5.8 million in cash in exchange for all outstanding shares of Ozark Trust common stock. Prior to the acquisition, Ozark Trust had over $1 billion in assets under management. The Company owned 1,000 shares of Ozark Trust’s common stock, which it acquired through its acquisition of Liberty in February 2015. The purchase price is allocated among the net assets of Ozark Trust acquired as appropriate, with the remaining balance being reported as goodwill. A summary, at fair value, of the assets acquired and liabilities assumed in the Ozark Trust transaction, as of the acquisition date, is as follows: (In thousands) Acquired from Fair Value Fair Assets Acquired Cash $ 1,756 $ -- $ 1,756 Investment securities 241 -- 241 Premises and equipment 1,126 418 1,544 Other intangibles -- 9,733 9,733 Other assets 752 -- 752 Total assets acquired $ 3,875 $ 10,151 $ 14,026 Liabilities Assumed Deferred tax liability 63 3,982 4,045 Accrued and other liabilities 302 -- 302 Total liabilities assumed 365 3,982 4,347 Equity 3,510 (3,510 ) -- Total equity assumed 3,510 (3,510 ) -- Total liabilities and equity assumed $ 3,875 $ 472 $ 4,347 Net assets acquired 9,679 Purchase price 23,623 Goodwill $ 13,944 The following is a description of the methods used to determine the fair values of significant assets and liabilities presented in the Ozark Trust acquisition above. Cash Investment securities Premises and equipment Goodwill Other intangibles Other assets Deferred tax liability The purchase price allocation and certain fair value measurements remain preliminary due to the timing of the acquisition. Management will continue to review the estimated fair values and to evaluate the assumed tax positions. The Company expects to finalize its analysis of the acquired assets and assumed liabilities in this transaction over the next few months, within one year of the acquisition. Therefore, adjustments to the estimated amounts and carrying values may occur. The Company’s operating results for 2015 include the operating results of the acquired assets and assumed liabilities of Ozark Trust subsequent to the acquisition date. This acquisition is not considered significant to the Company’s financial statements, and thus no proforma information is presented. Delta Trust & Banking Corporation On August 31, 2014, Simmons First National Corporation completed the acquisition of Delta Trust & Banking Corporation (“Delta Trust”), headquartered in Little Rock, Arkansas, including its wholly-owned bank subsidiary Delta Trust & Bank (“DTB”). Simmons issued 1,629,515 shares of its common stock valued at approximately $65.0 million as of August 29, 2014, plus $2.4 million in cash in exchange for all outstanding shares of Delta Trust common stock. Prior to the acquisition, Delta Trust conducted banking business from 9 branches located in central, south and northwest Arkansas. Including the effects of the purchase accounting adjustments, the Company acquired approximately $417 million in assets, approximately $312 million in loans including loan discounts and approximately $355 million in deposits. The Company completed the systems conversion and merged DTB into Simmons Bank on October 24, 2014.

This acquisition is not considered significant to the Company’s financial statements, and thus no proforma information is presented. Metropolitan National Bank On November 25, 2013, Simmons First National Corporation completed the acquisition of Metropolitan National Bank (“Metropolitan” or “MNB”), with its principal office located in Little Rock, Arkansas, pursuant to a Stock Purchase Agreement between the Company and Rogers Bancshares, Inc. (“RBI”), in which the Company purchased all the stock of Metropolitan for $53.6 million in cash. The acquisition was conducted in accordance with the provisions of Section 363 of the United States Bankruptcy Code. As part of the acquisition, Metropolitan was merged into Simmons Bank. The Company recorded $6.6 million of pre-tax merger costs related to the acquisition. Prior to the acquisition, Metropolitan conducted banking business from 45 branches located in central and northwest Arkansas. Including the effects of the purchase accounting adjustments, the Company acquired approximately $884 million in assets, approximately $457 million in loans, net of discounts, and $838 million of deposits.

Certain investment securities are valued at less than their historical cost. Total fair value of these investments at December 31, 2015 and 2014, was $872.4 million and $680.5 million, which is approximately 57.1% and 62.8%, respectively, of the Company’s combined available-for-sale and held-to-maturity investment portfolios.

Based on evaluation of available evidence, management believes the declines in fair value for these securities are temporary. Management does not have the intent to sell these securities and management believes it is more likely than not the Company will not have to sell these securities before recovery of their amortized cost basis less any current period credit losses. Declines in the fair value of held-to-maturity and available-for-sale securities below their cost that are deemed to be other than temporary are reflected in earnings as realized losses. In estimating other-than-temporary impairment losses, management considers, among other things, (i) the length of time and the extent to which the fair value has been less than cost, (ii) the financial condition and near-term prospects of the issuer, and (iii) the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value. Management has the ability and intent to hold the securities classified as held to maturity until they mature, at which time the Company expects to receive full value for the securities. Furthermore, as of December 31, 2015, management also had the ability and intent to hold the securities classified as available-for-sale for a period of time sufficient for a recovery of cost. The unrealized losses are largely due to increases in market interest rates over the yields available at the time the underlying securities were purchased. The fair value is expected to recover as the bonds approach their maturity date or repricing date or if market yields for such investments decline. Management does not believe any of the securities are impaired due to reasons of credit quality. Accordingly, as of December 31, 2015, management believes the impairments detailed in the table above are temporary. Should the impairment of any of these securities become other than temporary, the cost basis of the investment will be reduced and the resulting loss recognized in net income in the period the other-than-temporary impairment is identified. Income earned on the above securities for the years ended December 31, 2015, 2014 and 2013, is as follows: (In thousands) 2015 2014 2013 Taxable Held-to-maturity $ 5,162 $ 5,839 $ 3,314 Available-for-sale 12,129 2,785 2,239 Non-taxable Held-to-maturity 11,635 10,625 7,682 Available-for-sale 1,687 108 65 Total $ 30,613 $ 19,357 $ 13,300 The amortized cost and estimated fair value by maturity of securities are shown in the following table.

The book value of securities sold under agreements to repurchase amounted to $96.8 million and $100.8 million for December 31, 2015 and 2014, respectively. There were $350,000 of gross realized gains and $43,000 of realized losses from the sale of available for sale securities during the year ended December 31, 2015. There were $199,000 of gross realized gains and $191,000 of realized losses from the sale of available for sale securities during the year ended December 31, 2014. There were $151,000 of gross realized gains and $302,000 of realized losses from the sale of available for sale securities during the year ended December 31, 2013. As part of its strategy related to the 2012 acquisitions, the Company liquidated the acquired mortgage-backed securities, resulting in $193,000 of net realized losses during 2013. The income tax expense/benefit related to security gains/losses was 39.225% of the gross amounts. The state and political subdivision debt obligations are primarily non-rated bonds and represent small, Arkansas, Illinois, Kansas, Missouri, Tennessee and Texas issues, which are evaluated on an ongoing basis.

Allocations of the allowance for loan losses relative to impaired loans were $2.8 million and $2.1 million at December 31, 2015 and 2014, respectively. Approximately $1.2 million, $0.8 million and $0.9 million of interest income was recognized on average impaired loans of $16.7 million, $17.5 million and $21.6 million for 2015, 2014 and 2013, respectively. Interest recognized on impaired loans on a cash basis during 2015, 2014 and 2013 was not material. Included in certain impaired loan categories are troubled debt restructurings (“TDRs”). When the Company restructures a loan to a borrower that is experiencing financial difficulty and grants a concession that it would not otherwise consider, a “troubled debt restructuring” results and the Company classifies the loan as a TDR. The Company grants various types of concessions, primarily interest rate reduction and/or payment modifications or extensions, with an occasional forgiveness of principal. Under ASC Topic 310-10-35 – Subsequent Measurement Once an obligation has been restructured because of such credit problems, it continues to be considered a TDR until paid in full; or, if an obligation yields a market interest rate and no longer has any concession regarding payment amount or amortization, then it is not considered a TDR at the beginning of the calendar year after the year in which the improvement takes place. The Company returns TDRs to accrual status only if (1) all contractual amounts due can reasonably be expected to be repaid within a prudent period, and (2) repayment has been in accordance with the contract for a sustained period, typically at least six months. The following table presents a summary of troubled debt restructurings, excluding loans acquired, segregated by class of loans.

The restructured loans were modified by various terms, including changing the maturity date, deferring amortized principal payments and requiring interest only payments for a period of 12 months. Based on the fair value of the collateral, a specific reserve of $113,000 was determined necessary for these loans. Also, there was no immediate financial impact from the restructuring of these loans, as it was not considered necessary to charge-off interest or principal on the date of restructure. During year ended December 31, 2014, the Company modified three loans with a total recorded investment of $2,025,000 prior to modification which were deemed troubled debt restructuring. The restructured loans were modified by various terms, including changing the maturity date and deferring amortized principal payments. Based on the fair value of the collateral, no specific reserve was determined necessary for these loans. Also, there was no immediate financial impact from the restructuring of these loans, as it was not considered necessary to charge-off interest or principal on the date of restructure. During the year ended December 31, 2014, one of the restructured loans with a prior balance of $598,000 was paid off. There were no loans for which a payment default occurred during the years ended December 31, 2015 and 2014, and that had been modified as a TDR within 12 months or less of the payment default, excluding loans acquired. We define a payment default as a payment received more than 90 days after its due date. In addition to the TDRs that occurred during the period provided in the preceding tables, the Company had TDRs with pre-modification loan balances of $167,000 and $4,757,000 at December 31, 2015 and 2014, respectively, for which other real estate owned (“OREO”) was received in full or partial satisfaction of the loans. The majority of such TDRs were in commercial real estate and residential real estate. At December 31, 2015, the Company had $1,064,000 of consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceedings are in process. At December 31, 2015, the Company had $5,916,000 of OREO secured by residential real estate properties. Credit Quality Indicators The Company utilizes a risk rating matrix to assign a risk rate to each of its commercial and real estate loans. Loans are rated on a scale of 1 to 8. A description of the general characteristics of the 8 risk ratings is as follows: · Risk Rate 1 – Pass (Excellent) · Risk Rate 2 – Pass (Good) · Risk Rate 3 – Pass (Acceptable – Average) · Risk Rate 4 – Pass (Monitor) · Risk Rate 5 – Special Mention · Risk Rate 6 – Substandard · Risk Rate 7 – Doubtful · Risk Rate 8 – Loss Loans acquired are evaluated using this internal grading system. Loans acquired are evaluated individually and include purchased credit impaired loans of $23.5 million and $22.3 million that are accounted for under ASC Topic 310-30 and are classified as substandard (Risk Rating 6) as of December 31, 2015 and 2014, respectively. Of the remaining loans acquired and accounted for under ASC Topic 310-20, $49.9 million and $16.6 million were classified (Risk Ratings 6, 7 and 8 – see classified loans discussion below) at December 31, 2015 and 2014, respectively. Loans acquired, covered by loss share agreements, had additional protection provided by the FDIC prior to the termination of the loss share agreements. During the 2014 quarterly impairment testing on the estimated cash flows of the credit impaired loans, the Company established that some of the loans covered by loss share from our FDIC-assisted transactions had experienced material projected credit deterioration. As a result, the Company established a $954,000 allowance for loan losses on covered loans by recording a provision for loan losses of $0.4 million (net of FDIC-loss share adjustments) during the period ended December 31, 2014. There was no further projected credit deterioration and no addition to the allowance for covered loans in 2015. The $954,000 allowance was reclassified to allowance on acquired non-covered loans subsequent to the agreement with the FDIC to terminate the loss share agreements. See Note 5, Loans Acquired, for further discussion of the acquired loans, loan pools and loss sharing agreements. Purchased credit impaired loans are loans that showed evidence of deterioration of credit quality since origination and for which it is probable, at acquisition, that the Company will be unable to collect all amounts contractually owed. Their fair value was initially based on the estimate of cash flows, both principal and interest, expected to be collected or estimated collateral values if cash flows are not estimable, discounted at prevailing market rates of interest. The difference between the undiscounted cash flows expected at acquisition and the fair value at acquisition is recognized as interest income on a level-yield method over the life of the loan. Contractually required payments for interest and principal that exceed the undiscounted cash flows expected at acquisition are not recognized as a yield adjustment. Increases in expected cash flows subsequent to the initial investment are recognized prospectively through adjustment of the yield on the loan over its remaining life. Decreases in expected cash flows are recognized as impairment. Classified loans for the Company include loans in Risk Ratings 6, 7 and 8. Loans may be classified, but not considered impaired, due to one of the following reasons: (1) The Company has established minimum dollar amount thresholds for loan impairment testing. Loans rated 6 – 8 that fall under the threshold amount are not tested for impairment and therefore are not included in impaired loans. (2) Of the loans that are above the threshold amount and tested for impairment, after testing, some are considered to not be impaired and are not included in impaired loans. Total classified loans, excluding loans accounted for under ASC Topic 310-30, were $153.7 million and $82.1 million as of December 31, 2015 and December 31, 2014, respectively. The following table presents a summary of loans by credit risk rating, segregated by class of loans. Loans accounted for under ASC Topic 310-30 are all included in Risk Rate 1-4 in this table.

A loan is considered impaired when it is probable that the Company will not receive all amounts due according to the contractual terms of the loan, including scheduled principal and interest payments. For a collateral dependent loan, the Company’s evaluation process includes a valuation by appraisal or other collateral analysis. This valuation is compared to the remaining outstanding principal balance of the loan. If a loss is determined to be probable, the loss is included in the allowance for loan losses as a specific allocation. If the loan is not collateral dependent, the measurement of loss is based on the difference between the expected and contractual future cash flows of the loan. The general allocation is calculated monthly based on management’s assessment of several factors such as (1) historical loss experience based on volumes and types, (2) volume and trends in delinquencies and nonaccruals, (3) lending policies and procedures including those for loan losses, collections and recoveries, (4) national, state and local economic trends and conditions, (5) concentrations of credit within the loan portfolio, (6) the experience, ability and depth of lending management and staff and (7) other factors and trends that will affect specific loans and categories of loans. The Company establishes general allocations for each major loan category. This category also includes allocations to loans which are collectively evaluated for loss such as credit cards, one-to-four family owner occupied residential real estate loans and other consumer loans. The following table details activity in the allowance for loan losses, excluding loans acquired, by portfolio segment for the year ended December 31, 2015. Allocation of a portion of the allowance to one category of loans does not preclude its availability to absorb losses in other categories.

Loans Acquired [Abstract]
Loans Acquired [Text Block]	NOTE 5: LOANS ACQUIRED On September 15, 2015, the Company entered into an agreement with the FDIC to terminate all loss share agreements which were entered into in 2010 and 2012 in conjunction with the Company’s acquisition of substantially all of the assets (“covered assets”) and assumption of substantially all of the liabilities of four failed banks in FDIC-assisted transactions. Under the early termination, all rights and obligations of the Company and the FDIC under the FDIC loss share agreements, including the clawback provisions and the settlement of loss share and expense reimbursement claims, have been resolved and terminated. Under the terms of the agreement, the FDIC made a net payment of $2,368,000 to the bank as consideration for the early termination of the loss share agreements. The early termination was recorded in the Company’s financial statements by removing the FDIC Indemnification Asset, receivable from FDIC, the FDIC True-up liability and recording a one-time, pre-tax charge of $7,476,000. As a result, the Company reclassified loans previously covered by FDIC loss share to loans acquired, not covered by FDIC loss share. Foreclosed assets previously covered by FDIC loss share were reclassified to foreclosed assets not covered by FDIC loss share. During the first quarter of 2015, the Company evaluated $769.9 million of net loans ($774.8 million gross loans less $4.9 million discount) purchased in conjunction with the acquisition of Liberty, described in Note 2, Acquisitions, in accordance with the provisions of ASC Topic 310-20, Nonrefundable Fees and Other Costs Loans and Debt Securities Acquired with Deteriorated Credit Quality Also during the first quarter of 2015, the Company evaluated $1.13 billion of net loans ($1.15 billion gross loans less $23.7 million discount) purchased in conjunction with the acquisition of Community First, described in Note 2, Acquisitions, in accordance with the provisions of ASC Topic 310-20. The fair value discount is being accreted into interest income over the weighted average life of the loans using a constant yield method. These loans are not considered to be impaired loans. The Company evaluated the remaining $7.0 million of net loans ($10.1 million gross loans less $3.1 million discount) purchased in conjunction with the acquisition of Community First for impairment in accordance with the provisions of ASC Topic 310-30. During the third quarter of 2014, the Company evaluated $308.2 million of net loans ($316.1 million gross loans less $7.9 million discount) purchased in conjunction with the acquisition of Delta Trust, described in Note 2, Acquisitions, in accordance with the provisions of ASC Topic 310-20, Nonrefundable Fees and Other Costs Loans and Debt Securities Acquired with Deteriorated Credit Quality During the fourth quarter of 2013, the Company evaluated $429.0 million of net loans ($442.0 million gross loans less $13.0 million discount) purchased in conjunction with the acquisition of Metropolitan, described in Note 2, Acquisitions, in accordance with the provisions of ASC Topic 310-20. The fair value discount is being accreted into interest income over the weighted average life of the loans using a constant yield method. These loans are not considered to be impaired loans. The Company evaluated the remaining $28.4 million of net loans ($52.8 million gross loans less $24.5 million discount) purchased in conjunction with the acquisition of Metropolitan for impairment in accordance with the provisions of ASC Topic 310-30. Purchased loans are considered impaired if there is evidence of credit deterioration since origination and if it is probable that not all contractually required payments will be collected. See Note 2, Acquisitions, for further discussion of loans acquired.

These loans are systematically reviewed by the Company to determine the risk of losses that may exceed those identified at the time of the acquisition. Techniques used in determining risk of loss are similar to the Company’s legacy loan portfolio, with most focus being placed on those loans which include the larger loan relationships and those loans which exhibit higher risk characteristics. The following is a summary of the loans acquired in the Liberty acquisition on February 27, 2015, as of the date of acquisition.

The accretable yield is recognized as interest income over the estimated lives of the loans. Each quarter, the Company estimates the cash flows expected to be collected from the acquired purchased credit impaired loans, and adjustments may or may not be required. This has resulted in increased interest income that is spread on a level-yield basis over the remaining expected lives of the loans. For those loans previously covered by FDIC loss share, the increases in expected cash flows also reduced the amount of expected reimbursements under the loss sharing agreements with the FDIC, which was recorded as indemnification assets. The estimated adjustments to the indemnification assets were amortized on a level-yield basis over the remainder of the loss-sharing agreements or the remaining expected lives of the loans, whichever was shorter. Because the Company’s loss share agreements with the FDIC have been terminated, there will be no further indemnification asset amortization in future quarters. The impact of the adjustments on the Company’s financial results for the years ended December 31, 2015 and 2014 is shown below: (In thousands) 2015 2014 Impact on net interest income $ 19,995 $ 26,400 Non-interest income (1) (7,719 ) (20,540 ) Net impact to pre-tax income 12,276 5,860 Net impact, net of taxes $ 7,461 $ 3,561 (1) Negative non-interest income resulted from the amortization of the FDIC indemnification assets. Because the Company’s loss share agreements with the FDIC have been terminated, there will be no further indemnification asset amortization. These adjustments will be recognized over the remaining lives of the loans for purchased credit impaired loans. The accretable yield adjustments recorded in future periods will change as the Company continues to evaluate expected cash flows from the purchased credit impaired loans. Changes in the carrying amount of the accretable yield for all purchased impaired loans were as follows for the years ended December 31, 2015, 2014 and 2013. (in thousands) Accretable Carrying Balance, January 1, 2013 $ 58,066 $ 293,606 Additions 2,516 28,352 Accretable yield adjustments 17,380 -- Accretion (36,577 ) 36,577 Payments and other reductions, net -- (123,750 ) Balance, December 31, 2013 41,385 234,785 Additions 177 3,526 Accretable yield adjustments 9,104 -- Accretion (30,031 ) 30,031 Payments and other reductions, net -- (99,244 ) Balance, December 31, 2014 20,635 169,098 Additions (116 ) 17,750 Accretable yield adjustments 6,593 -- Accretion (21,038 ) 21,038 Payments and other reductions, net (5,120 ) (184,417 ) Balance, December 31, 2015 $ 954 $ 23,469 Purchased impaired loans are evaluated on an individual borrower basis. Because some loans evaluated by the Company, previously covered by loss share agreements, were determined to have experienced impairment in the estimated credit quality or cash flows during 2014, the Company recorded a provision to establish a $954,000 allowance for loan losses for covered purchased impaired loans. During 2015, the Company recorded a provision totaling $736,000 to cover impairment in the estimated credit quality of acquired loans, not covered by loss share. Non-covered loans were subsequently charged-off and the allowance was used during 2015. Because of the termination of the loss share agreements, the allowance for previously covered loans was reclassified to allowance for acquired non-covered loans, resulting in a total allowance on acquired non-covered loans of $954,000 at December 31, 2015. The purchase and assumption agreements for the FDIC-assisted acquisitions allowed for the FDIC to recover a portion of the funds previously paid out under the indemnification agreement in the event losses failed to reach the expected loss level under a claw back provision (“true-up provision”). The amount of the true-up provision for each acquisition was measured and recorded at Day 1 fair values. It was calculated as the difference between management’s estimated losses on covered loans and covered foreclosed assets and the loss threshold contained in each loss share agreement, multiplied by the applicable clawback provisions contained in each loss share agreement, then discounted back to net present value. Under the terms of the loss share termination agreement, the FDIC made a net payment of $2.4 million to the bank as consideration for early termination. The early termination was recorded in the Company’s financial statements by removing the FDIC indemnification asset, receivable from FDIC, the FDIC true-up provision and recording a one-time, pre-tax charge of $7.5 million. The following table presents a summary of the changes in the FDIC true-up provision for years ended December 31, 2015, 2014 and 2013, which is included in other assets on the balance sheet.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets Disclosure [Text Block]	NOTE 6: GOODWILL AND OTHER INTANGIBLE ASSETS Goodwill is tested annually, or more often than annually, if circumstances warrant, for impairment. If the implied fair value of goodwill is lower than its carrying amount, goodwill impairment is indicated, and goodwill is written down to its implied fair value. Subsequent increases in goodwill value are not recognized in the financial statements. Goodwill totaled $327.7 million at December 31, 2015 and $108.1 million at December 31, 2014. The Company recorded $95.2 million, $110.4 million and $13.9 million of goodwill during 2015 as a result of its acquisitions of Liberty, Community First and Ozark Trust, respectively. The Company recorded $29.0 million of goodwill during 2014 as a result of its Delta Trust acquisition. Goodwill impairment was neither indicated nor recorded in 2015, 2014 or 2013. Core deposit premiums are amortized over a ten year period and are periodically evaluated, at least annually, as to the recoverability of their carrying value. Core deposit premiums of $11.3 million and $14.6 million were recorded in 2015 as part of the Community First and Liberty acquisitions, respectively. During the third quarter of 2015, the Company sold the Salina banking operations and as a result reduced the related core deposit premium by $382,000. Core deposit premiums of $4.3 million were recorded in 2014 as part of the Delta Trust acquisition. The Community First acquisition included an insurance line of business and the Company recorded an intangible asset of $420,000 during the first quarter of 2015. The Company recorded $9.7 million of intangible assets during the fourth quarter of 2015 related to the trust operations acquired in the Ozark Trust merger. The Delta Trust acquisition included some significant lines of business related to investments, trust and insurance. The Company recorded $5.1 million of intangible assets related to those acquired lines of business during the third quarter of 2014. These intangible assets are being amortized over various periods ranging from 10 to 15 years. The Company’s goodwill and other intangibles (carrying basis and accumulated amortization) at December 31, 2015 and 2014 were as follows: (In thousands) 2015 2014 Goodwill $ 327,686 $ 108,095 Core deposit premiums: Gross carrying amount 43,648 18,318 Accumulated amortization (6,217 ) (2,386 ) Core deposit premiums, net 37,431 15,932 Purchased credit card relationships: Gross carrying amount 2,068 2,068 Accumulated amortization (931 ) (517 ) Purchased credit card relationships, net 1,137 1,551 Books of business intangible: Gross carrying amount 15,293 5,140 Accumulated amortization (624 ) (97 ) Books of business intangible, net 14,669 5,043 Other intangible assets, net 53,237 22,526 Total goodwill and other intangible assets $ 380,923 $ 130,621 Core deposit premium amortization expense recorded for the years ended December 31, 2015, 2014 and 2013 was $3.9 million, $1.4 million and $600,000, respectively.

The debt has a 10 year amortization with a 5 year balloon payment due in October 2020. The Company used approximately $36 million of this borrowing to refinance the debt issued during 2013 that was used to partially fund the acquisition of Metropolitan. At December 31, 2015, the Company had $40.0 million of Federal Home Loan Bank (“FHLB”) advances with original maturities of one year or less. During 2015 the Company early extinguished FHLB advances with principal balances of $22 million. The consideration paid for the early extinguishment was $23.2 million representing the net settlement of the advance balances and prepayment penalties of $1.3 million. These penalties were partially offset by the remaining acquisition market adjustment balances on these borrowings. The resulting net loss of $782,000 was recorded in interest expense. The Company had total FHLB advances of $109.9 million at December 31, 2015, with approximately $965 million of additional advances available from the FHLB. The FHLB advances are secured by mortgage loans and investment securities totaling approximately $1.1 billion at December 31, 2015. The trust preferred securities are tax-advantaged issues that qualify for Tier 1 capital treatment. Distributions on these securities are included in interest expense on long-term debt. Each of the trusts is a statutory business trust organized for the sole purpose of issuing trust securities and investing the proceeds thereof in junior subordinated debentures of the Company, the sole asset of each trust. The preferred securities of each trust represent preferred beneficial interests in the assets of the respective trusts and are subject to mandatory redemption upon payment of the junior subordinated debentures held by the trust. The common securities of each trust are wholly-owned by the Company.

Capital Stock Disclosure [Abstract]
Capital Stock Disclosure [Text Block]	NOTE 11: CAPITAL STOCK On February 27, 2009, at a special meeting, the Company’s shareholders approved an amendment to the Articles of Incorporation to establish 40,040,000 authorized shares of preferred stock, $0.01 par value. The aggregate liquidation preference of all shares of preferred stock cannot exceed $80,000,000. On February 27, 2015, as part of the acquisition of Community First, the Company issued 30,852 shares of Senior Non-Cumulative Perpetual Preferred Stock, Series A (“Simmons Series A Preferred Stock”) in exchange for the outstanding shares of Community First Senior Non-Cumulative Perpetual Preferred Stock, Series C (“Community First Series C Preferred Stock”). The preferred stock is held by the United States Department of the Treasury (“Treasury”) as the Community First Series C Preferred Stock was issued when Community First entered into a Small Business Lending Fund Securities Purchase Agreement with the Treasury. The Simmons Series A Preferred Stock qualifies as Tier 1 capital and will pay quarterly dividends. The rate will remain fixed at 1% through February 18, 2016, at which time it will convert to a fixed rate of 9%. On January 29, 2016, the Company redeemed all of the preferred stock, including accrued and unpaid dividends. On July 23, 2012, the Company approved a stock repurchase program which authorized the repurchase of up to 850,000 shares of Class A common stock, or approximately 5% of the shares outstanding. The shares are to be purchased from time to time at prevailing market prices, through open market or unsolicited negotiated transactions, depending upon market conditions. Under the repurchase program, there is no time limit for the stock repurchases, nor is there a minimum number of shares that the Company intends to repurchase. The Company may discontinue purchases at any time that management determines additional purchases are not warranted. The Company intends to use the repurchased shares to satisfy stock option exercises, payment of future stock awards and dividends and general corporate purposes. During 2013, the Company repurchased 419,564 shares of stock with a weighted average repurchase price of $25.89 per share. Under the current stock repurchase plan, the Company can repurchase an additional 154,136 shares. As a result of its announced acquisition of Metropolitan, the Company suspended its stock repurchases in August of 2013. See Note 2, Acquisitions, for additional information on the Metropolitan acquisition. On March 4, 2014 the Company filed a shelf registration statement with the Securities and Exchange Commission (“SEC”). Subsequently, on June 18, 2014 the Company filed Amendment No. 1 to the shelf registration statement. After becoming effective, the shelf registration statement allows the Company to raise capital from time to time, up to an aggregate of $300 million, through the sale of common stock, preferred stock, stock warrants, stock rights or a combination thereof, subject to market conditions. Specific terms and prices are determined at the time of any offering under a separate prospectus supplement that the Company is required to file with the SEC at the time of the specific offering.

Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	NOTE 13: EMPLOYEE BENEFIT PLANS Retirement Plans The Company’s 401(k) retirement plan covers substantially all employees. Contribution expense totaled $1,048,000, $837,000 and $690,000, in 2015, 2014 and 2013, respectively. The Company has a discretionary profit sharing and employee stock ownership plan covering substantially all employees. Contribution expense totaled $5,230,000 for 2015, $3,659,000 for 2014 and $3,076,000 for 2013. The Company also provides deferred compensation agreements with certain active and retired officers. The agreements provide monthly payments of retirement compensation for either stated periods or for the life of the participant. The charges to income for the plans were $804,000 for 2015, $453,000 for 2014 and $473,000 for 2013. Such charges reflect the straight-line accrual over the employment period of the present value of benefits due each participant, as of their full eligibility date, using an appropriate discount factor. Employee Stock Purchase Plan The Company established an Employee Stock Purchase Plan in 2011 which generally allows participants to make contributions of up 3% of the employee’s salary, up to a maximum of $7,500 per year, for the purpose of acquiring the Company’s stock. Substantially all employees with at least two years of service are eligible for the plan. At the end of each plan year, full shares of the Company’s stock are purchased for each employee based on that employee’s contributions. The stock is purchased for an amount equal to 95% of its fair market value at the end of the plan year, or, if lower, 95% of its fair market value at the beginning of the plan year. The Company established a Special Employee Stock Purchase Plan in 2015 which generally allows participants to make contributions up to cumulative sum in all plans of $25,000 per calendar year, for the purpose of acquiring the Company’s stock. Substantially all non-highly compensated employees with at least two years of service are eligible for the plan. At the end of each plan year, full shares of the Company’s stock are purchased for each employee based on that employee’s contributions. The stock is purchased for an amount equal to 85% of its fair market value at the end of the plan year, or, if lower, 85% of its fair market value at the beginning of the plan year. Stock-Based Compensation Plans The Company’s Board of Directors has adopted various stock-based compensation plans. The plans provide for the grant of incentive stock options, nonqualified stock options, stock appreciation rights, and bonus stock awards. Pursuant to the plans, shares are reserved for future issuance by the Company upon exercise of stock options or awarding of bonus shares granted to directors, officers and other key employees. Stock-based compensation expense for all stock-based compensation awards granted after January 1, 2006, is based on the grant date fair value. For all awards except stock option awards, the grant date fair value is the market value per share as of the grant date. For stock option awards, the fair value is estimated at the date of grant using the Black-Scholes option-pricing model. This model requires the input of highly subjective assumptions, changes to which can materially affect the fair value estimate. Additionally, there may be other factors that would otherwise have a significant effect on the value of employee stock options granted but are not considered by the model. Accordingly, while management believes that the Black-Scholes option-pricing model provides a reasonable estimate of fair value, the model does not necessarily provide the best single measure of fair value for the Company's employee stock options. The fair value of each option award is estimated on the date of grant using the Black-Scholes option-pricing model that uses various assumptions. Expected volatility is based on historical volatility of the Company’s stock and other factors. The Company uses historical data to estimate option exercise and employee termination within the valuation model. The expected term of options granted is derived from the output of the option valuation model and represents the period of time that options granted are expected to be outstanding. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. Forfeitures are estimated at the time of grant, and are based partially on historical experience. The table below summarizes the transactions under the Company's active stock compensation plans at December 31, 2015, 2014 and 2013, and changes during the years then ended: Stock Options Non-Vested Stock Number Weighted Number Weighted Balance, December 31, 2012 218 $ 26.77 134 $ 25.89 Granted -- -- 75 26.89 Stock Options Exercised (24 ) 24.88 -- -- Stock Awards Vested -- -- (63 ) 26.82 Forfeited/Expired (9 ) 26.16 (1 ) 26.54 Balance, December 31, 2013 185 27.04 145 26.00 Granted -- -- 134 37.51 Stock Options Exercised (65 ) 25.86 -- -- Stock Awards Vested -- -- (51 ) 30.62 Forfeited/Expired -- -- (1 ) 26.54 Balance, December 31, 2014 120 27.72 227 31.88 Granted 375 44.69 95 43.45 Stock Options Exercised (71 ) 22.57 -- -- Stock Options from Acquisitions 66 20.43 -- -- Stock Awards Vested -- -- (131 ) 34.77 Forfeited/Expired (5 ) 24.49 (8 ) 35.36 Balance, December 31, 2015 485 $ 40.59 183 $ 35.65 Exercisable, December 31, 2015 238 $ 36.90 The following table summarizes information about stock options under the plans outstanding at December 31, 2015: Options Outstanding Options Exercisable Range of Exercise Prices Number Weighted Weighted Number Weighted $15.55 - $21.29 24 4.86 $ 19.41 13 $ 18.53 21.51 - 21.51 2 4.05 21.51 2 21.51 26.19 - 26.19 25 0.38 26.19 25 26.19 28.42 - 28.42 27 1.36 28.42 27 28.42 30.31 - 30.31 30 2.27 30.31 30 30.31 40.57 - 40.57 49 7.63 40.57 49 40.57 40.72 - 40.72 2 8.88 40.72 -- 40.72 44.40 - 44.40 65 7.55 44.40 14 44.40 45.50 - 45.50 258 9.05 45.50 77 45.50 48.13 - 48.13 3 9.71 48.13 1 48.13 $15.55 - $48.13 485 7.19 $ 40.59 238 $ 36.90 Stock-based compensation expense was $4,018,000 in 2015, $1,366,000 in 2014 and $1,417,000 in 2013. Stock-based compensation expense is recognized ratably over the requisite service period for all stock-based awards. There was $1,442,000 of unrecognized stock-based compensation expense related to stock options at December 31, 2015. Unrecognized stock-based compensation expense related to non-vested stock awards was $5.3 million at December 31, 2015. At such date, the weighted-average period over which this unrecognized expense is expected to be recognized was 3.3 years. The intrinsic value of stock options outstanding and stock options exercisable at December 31, 2015 was $5,219,000 and $3,448,000. Aggregate intrinsic value represents the difference between the Company’s closing stock price on the last trading day of the period, which was $51.36 at December 31, 2015, and the exercise price multiplied by the number of options outstanding. There were 71,368 stock options exercised in 2015, with an intrinsic value of $2,054,000. There were 64,720 stock options exercised in 2014, with an intrinsic value of $957,000. There were 24,290 stock options exercised in 2013, with an intrinsic value of $298,000. The fair value of the Company’s employee stock options granted is estimated on the date of grant using the Black-Scholes option-pricing model. This model requires the input of highly subjective assumptions, changes to which can materially affect the fair value estimate. The weighted-average fair value of stock options granted during the year ended December 31, 2015 was $7.81 per share. There were no stock options granted during the years ended December 31, 2014 or 2013. The Company estimated expected market price volatility and expected term of the options based on historical data and other factors. The weighted-average assumptions used to determine the fair value of options granted are detailed in the table below: Year Ended December 31, 2015 Expected dividend yield 2.06 % Expected stock price volatility 16.96 % Risk-free interest rate 2.17 % Expected life of options (years) 10

Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	NOTE 16: DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS ASC Topic 820, Fair Value Measurements ASC Topic 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The guidance also establishes a fair value hierarchy that requires the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. Topic 820 describes three levels of inputs that may be used to measure fair value: · Level 1 Inputs · Level 2 Inputs · Level 3 Inputs In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon internally developed models that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect counterparty credit quality and the Company’s creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. The Company’s valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While management believes the Company’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Furthermore, the reported fair value amounts have not been comprehensively revalued since the presentation dates, and therefore, estimates of fair value after the balance sheet date may differ significantly from the amounts presented herein. A more detailed description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. Following is a description of the inputs and valuation methodologies used for assets measured at fair value on a recurring basis and recognized in the accompanying consolidated balance sheets, as well as the general classification of such assets pursuant to the valuation hierarchy. Available-for-sale securities Assets held in trading accounts The following table sets forth the Company’s financial assets by level within the fair value hierarchy that were measured at fair value on a recurring basis as of December 31, 2015 and 2014. Fair Value Measurements (In thousands) Fair Value Quoted Prices in Significant Other Significant December 31, 2015 ASSETS Available-for-sale securities U.S. Treasury $ 3,994 $ 3,994 $ -- $ -- U.S. Government agencies 120,237 -- 120,237 -- Mortgage-backed securities 647,426 -- 647,426 -- States and political subdivisions 9,874 -- 9,874 -- Other securities 39,876 -- 39,876 -- Assets held in trading accounts 4,422 2,409 2,013 -- December 31, 2014 ASSETS Available-for-sale securities U.S. Treasury $ 3,992 3,992 $ -- $ U.S. Government agencies 272,816 -- 272,816 -- Mortgage-backed securities 1,572 -- 1,572 -- States and political subdivisions 6,540 -- 6,540 -- Other securities 20,363 -- 20,363 -- Assets held in trading accounts 6,987 3,320 3,667 -- Certain financial assets and liabilities are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). Financial assets and liabilities measured at fair value on a nonrecurring basis include the following: Impaired loans (collateral dependent) Appraisals are updated at renewal, if not more frequently, for all collateral dependent loans that are deemed impaired by way of impairment testing. Impairment testing for selected loans rated Special Mention or worse begins at $500,000, with testing on all loans over $1.5 million rated Special Mention or worse. All collateral dependent impaired loans meeting these thresholds have had updated appraisals or internally prepared evaluations within the last one to two years and these updated valuations are considered in the quarterly review and discussion of the corporate Special Asset Committee. On targeted CRE loans, appraisals/internally prepared valuations may be updated before the typical 1-3 year balloon/maturity period. If an updated valuation results in decreased value, a specific (ASC 310) impairment is placed against the loan, or a partial charge-down is initiated, depending on the circumstances and anticipation of the loan’s ability to remain a going concern, possibility of foreclosure, certain market factors, etc. Foreclosed assets held for sale The significant unobservable inputs (Level 3) used in the fair value measurement of collateral for collateral-dependent impaired loans and foreclosed assets primarily relate to the specialized discounting criteria applied to the borrower’s reported amount of collateral. The amount of the collateral discount depends upon the condition and marketability of the collateral, as well as other factors which may affect the collectability of the loan. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset. It is reasonably possible that a change in the estimated fair value for instruments measured using Level 3 inputs could occur in the future. As the Company’s primary objective in the event of default would be to liquidate the collateral to settle the outstanding balance of the loan, collateral that is less marketable would receive a larger discount. During the reported periods, collateral discounts ranged from 10% to 40% for commercial and residential real estate collateral. Mortgage loans held for sale The following table sets forth the Company’s financial assets by level within the fair value hierarchy that were measured at fair value on a nonrecurring basis as of December 31, 2015 and 2014.

ASC Topic 825, Financial Instruments Cash and cash equivalents Interest bearing balances due from banks Held-to-maturity securities Loans Loans acquired FDIC indemnification asset Deposits Federal Funds purchased, securities sold under agreement to repurchase and short-term debt Other borrowings Subordinated debentures Accrued interest receivable/payable Commitments to extend credit, letters of credit and lines of credit The fair value of a financial instrument is the current amount that would be exchanged between willing parties, other than in a forced liquidation. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company’s various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. The estimated fair values, and related carrying amounts, of the Company’s financial instruments not previously disclosed are as follows: Carrying Fair Value Measurements (In thousands) Amount Level 1 Level 2 Level 3 Total December 31, 2015 Financial assets: Cash and cash equivalents $ 252,262 $ 252,262 $ -- $ -- $ 252,262 Interest bearing balances due from banks - time 14,107 -- 14,105 -- 14,105 Held-to-maturity securities 705,373 -- 713,371 -- 713,371 Mortgage loans held for sale 30,265 -- -- 30,265 30,265 Interest receivable 25,793 -- 25,793 -- 25,793 Legacy loans (net of allowance) 3,215,103 -- -- 3,204,153 3,204,153 Loans acquired (net of allowance) 1,672,901 -- -- 1,667,204 1,667,204 Financial liabilities: Non-interest bearing transaction accounts 1,280,234 -- 1,280,234 -- 1,280,234 Interest bearing transaction accounts and savings deposits 3,485,845 -- 3,485,845 -- 3,485,845 Time deposits 1,320,017 -- -- 1,315,254 1,315,254 Federal funds purchased and securities sold under agreements to repurchase 99,398 -- 99,398 -- 99,398 Other borrowings 162,289 -- 168,254 -- 168,254 Subordinated debentures 60,570 -- 55,954 -- 55,954 Interest payable 1,800 -- 1,800 -- 1,800 December 31, 2014 Financial assets Cash and cash equivalents $ 335,909 $ 335,909 $ -- $ -- $ 335,909 Held-to-maturity securities 777,587 -- 780,533 -- 780,533 Mortgage loans held for sale 21,265 -- -- 21,265 21,265 Interest receivable 16,774 -- 16,774 -- 16,774 Legacy loans (net of allowance) 2,024,693 -- -- 2,022,889 2,022,889 Loans acquired, not covered by FDIC loss share 575,980 -- -- 560,651 560,651 Loans acquired, covered by FDIC loss share (net of allowance) 106,933 -- -- 105,789 105,789 FDIC indemnification asset 22,663 -- -- 22,663 22,663 Financial liabilities: Non-interest bearing transaction accounts 889,260 -- 889,260 -- 889,260 Interest bearing transaction accounts and savings deposits 2,006,271 -- 2,006,271 -- 2,006,271 Time deposits 965,187 -- -- 967,900 967,900 Federal funds purchased and securities sold under agreements to repurchase 110,586 -- 110,586 -- 110,586 Other borrowings 114,682 -- 114,698 -- 114,698 Subordinated debentures 20,620 -- 16,115 -- 16,115 Interest payable 1,147 -- 1,147 -- 1,147 The fair value of commitments to extend credit, letters of credit and lines of credit is not presented since management believes the fair value to be insignificant.

Disclosure Text Block Supplement [Abstract]
Commitments Disclosure [Text Block]	NOTE 17: COMMITMENTS AND CREDIT RISK The Company grants agri-business, credit card, commercial and residential loans to customers throughout Arkansas, Kansas, Missouri and Tennessee. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since a portion of the commitments may expire without being drawn upon, the total commitment 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. At December 31, 2015, the Company had outstanding commitments to extend credit aggregating approximately $497,961,000 and $805,673,000 for credit card commitments and other loan commitments, respectively. At December 31, 2014, the Company had outstanding commitments to extend credit aggregating approximately $480,653,000 and $439,053,000 for credit card commitments and other loan commitments, respectively. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements, including commercial paper, bond financing and similar transactions. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers. The Company had total outstanding letters of credit amounting to $23,515,000 and $16,217,000 at December 31, 2015 and 2014, respectively, with terms ranging from 9 months to 15 years. At December 31, 2015, the Company had no deferred revenue under standby letter of credit agreements and approximately $13,000 at December 31, 2014. At December 31, 2015, the Company did not have concentrations of 5% or more of the investment portfolio in bonds issued by a single municipality.

Stockholders' Equity Note [Abstract]
Stockholders' Equity Note Disclosure [Text Block]	NOTE 20: STOCKHOLDERS’ EQUITY The Company’s subsidiary bank is subject to a legal limitation on dividends that can be paid to the parent company without prior approval of the applicable regulatory agencies. The approval of the Office of the Comptroller of the Currency is required if the total of all the dividends declared by a national bank in any calendar year exceeds the total of its net profits, as defined, for that year, combined with its retained net profits of the preceding two years. At December 31, 2015, the Company subsidiary bank had approximately $8.2 million in undivided profits available for payment of dividends to the Company without prior approval of the regulatory agencies. The Company’s subsidiary bank is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company must meet specific capital guidelines that involve quantitative measures of the Company’s assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The Company’s capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Furthermore, the Company’s regulators could require adjustments to regulatory capital not reflected in these financial statements. Effective January 1, 2015, the Company and the Bank became subject to new capital regulations (the “Basel III Capital Rules”) adopted by the Federal Reserve in July 2013 establishing a new comprehensive capital framework for U.S. Banks. The Basel III Capital Rules substantially revise the risk-based capital requirements applicable to bank holding companies and depository institutions compared to the previous U.S. risk-based capital rules. Full compliance with all of the final rule’s requirements will be phased in over a multi-year schedule. The final rules include a new common equity Tier 1 capital to risk-weighted assets (CET1) ratio of 4.5% and a common equity Tier 1 capital conservation buffer of 2.5% of risk-weighted assets. CET1 generally consists of common stock; retained earnings; accumulated other comprehensive income and certain minority interests; all subject to applicable regulatory adjustments and deductions. The new capital conservation buffer requirement is to be phased in beginning on January 1, 2016 when a buffer greater than 0.625% of risk-weighted assets will be required, which amount will increase each year until the buffer requirement is fully implemented on January 1, 2019. Quantitative measures established by regulation to ensure capital adequacy require the Company to maintain minimum amounts and ratios (set forth in the table below) of total, Tier 1 and common equity Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined) and of Tier 1 capital (as defined) to average assets (as defined). Management believes that, as of December 31, 2015, the Company meets all capital adequacy requirements to which it is subject. As of the most recent notification from regulatory agencies, the subsidiaries were well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, the Company and its subsidiary bank must maintain minimum total risk-based, Tier 1 risk-based, common equity 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 the institutions’ categories. The Company’s and the subsidiary Bank’s actual capital amounts and ratios are presented in the following table.

Accounting Policies, by Policy (Policies)	12 Months Ended

Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	Nature of Operations and Principles of Consolidation Simmons First National Corporation (the “Company”) is primarily engaged in providing a full range of banking services to individual and corporate customers through its subsidiaries and their branch banks with offices in Arkansas, Kansas, Missouri and Tennessee. The Company is subject to competition from other financial institutions. The Company also is subject to the regulation of certain federal and state agencies and undergoes periodic examinations by those regulatory authorities. The consolidated financial statements include the accounts of Simmons First National Corporation and its subsidiaries. Significant intercompany accounts and transactions have been eliminated in consolidation.
Segment Reporting, Policy [Policy Text Block]	Operating Segments The Company is organized on a regional basis upon which management makes decisions regarding how to allocate resources and assess performance. Each of the regions provides a group of similar community banking services, including such products and services as loans; time deposits, checking and savings accounts; personal and corporate trust services; credit cards; investment management; insurance; and securities and investment services. Loan products include consumer, real estate, commercial, agricultural, equipment and SBA lending. The individual bank regions have similar operating and economic characteristics and have been reported as one aggregated operating segment. The Company also considers its trust, investment and insurance services to be operating segments. Information on these segments is not reported separately since they do not meet the quantitative thresholds under ASC Topic 280-10-50-12.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses, the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans and the valuation of covered loans and related indemnification asset. In connection with the determination of the allowance for loan losses and the valuation of foreclosed assets, management obtains independent appraisals for significant properties.
Reclassification, Policy [Policy Text Block]	Reclassifications Various items within the accompanying consolidated financial statements for previous years have been reclassified to provide more comparative information. These reclassifications had no effect on net earnings.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash Equivalents The Company considers all liquid investments with original maturities of three months or less to be cash equivalents. For purposes of the consolidated statements of cash flows, cash and cash equivalents are considered to include cash and non-interest bearing balances due from banks, interest bearing balances due from banks and federal funds sold and securities purchased under agreements to resell.
Investment, Policy [Policy Text Block]	Investment Securities Held-to-maturity securities, which include any security for which the Company has the positive intent and ability to hold until maturity, are carried at historical cost adjusted for amortization of premiums and accretion of discounts. Premiums and discounts are amortized and accreted, respectively, to interest income using the constant yield method over the period to maturity. Available-for-sale securities, which include any security for which the Company has no immediate plan to sell but which may be sold in the future, are carried at fair value. Realized gains and losses, based on specifically identified amortized cost of the individual security, are included in other income. Unrealized gains and losses are recorded, net of related income tax effects, in stockholders' equity. Premiums and discounts are amortized and accreted, respectively, to interest income using the constant yield method over the period to maturity. Trading securities, which include any security held primarily for near-term sale, are carried at fair value. Gains and losses on trading securities are included in other income. The Company applies accounting guidance related to recognition and presentation of other-than-temporary impairment under ASC Topic 320-10. When the Company does not intend to sell a debt security, and it is more likely than not, the Company will not have to sell the security before recovery of its cost basis, it recognizes the credit component of an other-than-temporary impairment of a debt security in earnings and the remaining portion in other comprehensive income. For held-to-maturity debt securities, the amount of an other-than-temporary impairment recorded in other comprehensive income for the noncredit portion of a previous other-than-temporary impairment is amortized prospectively over the remaining life of the security on the basis of the timing of future estimated cash flows of the security. As a result of this guidance, the Company’s consolidated statements of income reflect the full impairment (that is, the difference between the security’s amortized cost basis and fair value) on debt securities that the Company intends to sell or would more likely than not be required to sell before the expected recovery of the amortized cost basis. For available-for-sale and held-to-maturity debt securities that management has no intent to sell and believes that it more likely than not will not be required to sell prior to recovery, only the credit loss component of the impairment is recognized in earnings, while the noncredit loss is recognized in accumulated other comprehensive income. The credit loss component recognized in earnings is identified as the amount of principal cash flows not expected to be received over the remaining term of the security as projected based on cash flow projections.
Loans and Leases Receivable, Mortgage Banking Activities, Policy [Policy Text Block]	Mortgage Loans Held For Sale Mortgage loans held for sale are carried at the lower of cost or fair value, determined using an aggregate basis. Write-downs to fair value are recognized as a charge to earnings at the time the decline in value occurs. Forward commitments to sell mortgage loans are acquired to reduce market risk on mortgage loans in the process of origination and mortgage loans held for sale. The forward commitments acquired by the Company for mortgage loans in process of origination are not mandatory forward commitments. These commitments are structured on a best efforts basis; therefore, the Company is not required to substitute another loan or to buy back the commitment if the original loan does not fund. Typically, the Company delivers the mortgage loans within a few days after the loans are funded. These commitments are derivative instruments and their fair values at December 31, 2015 and 2014 are not material. Gains and losses resulting from sales of mortgage loans are recognized when the respective loans are sold to investors. Gains and losses are determined by the difference between the selling price and the carrying amount of the loans sold, net of discounts collected or paid. Fees received from borrowers to guarantee the funding of mortgage loans held for sale are recognized as income or expense when the loans are sold or when it becomes evident that the commitment will not be used.
Finance, Loan and Lease Receivables, Held-for-investment, Policy [Policy Text Block]	Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-offs are reported at their outstanding principal adjusted for any loans charged off, the allowance for loan losses and any unamortized deferred fees or costs on originated loans and unamortized premiums or discounts on purchased loans. For loans amortized at cost, interest income is accrued based on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, as well as premiums and discounts, are deferred and amortized as a level yield adjustment over the respective term of the loan. The accrual of interest on loans, except on certain government guaranteed loans, is discontinued at the time the loan is 90 days past due unless the credit is well-secured and in process of collection. Past due status is based on contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged off at an earlier date if collection of principal or interest is considered doubtful. Discounts and premiums on purchased residential real estate loans are amortized to income using the interest method over the remaining period to contractual maturity, adjusted for anticipated prepayments. Discounts and premiums on purchased consumer loans are recognized over the expected lives of the loans using methods that approximate the interest method. For discussion of the Company’s accounting for acquired loans, see Acquisition Accounting, Covered Loans and Related Indemnification Asset later in this section.
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	Allowance for Loan Losses The allowance for loan losses is management’s estimate of probable losses in the loan portfolio. Loan losses are charged against the allowance when management believes the uncollectability of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Allocations to the allowance for loan losses are categorized as either general reserves or specific reserves. The general reserve is calculated monthly based on management’s assessment of several factors such as (1) historical loss experience based on volumes and types, (2) volume and trends in delinquencies and nonaccruals, (3) lending policies and procedures including those for loan losses, collections and recoveries, (4) national, state and local economic trends and conditions, (5) concentrations of credit within the loan portfolio, (6) the experience, ability and depth of lending management and staff and (7) other factors and trends that will affect specific loans and categories of loans. The Company establishes general allocations for each major loan category and risk rating. This category also includes allocations to loans which are collectively evaluated for loss such as credit cards, one-to-four family owner occupied residential real estate loans and other consumer loans. General reserves have been established, based upon the aforementioned factors and allocated to the individual loan categories. Specific reserves are provided on loans that are considered impaired when it is probable that we will not receive all amounts due according to the contractual terms of the loan, including scheduled principal and interest payments. This includes loans that are delinquent 90 days or more, nonaccrual loans and certain other loans identified by management. Certain other loans identified by management consist of performing loans where management expects that the Company will not receive all amounts due according to the contractual terms of the loan, including scheduled principal and interest payments. Specific reserves are accrued for probable losses on specific loans evaluated for impairment for which the basis of each loan, including accrued interest, exceeds the discounted amount of expected future collections of interest and principal or, alternatively, the fair value of loan collateral. Accrual of interest is discontinued and interest accrued and unpaid is removed at the time such amounts are delinquent 90 days unless management is aware of circumstances which warrant continuing the interest accrual. Interest is recognized for nonaccrual loans only upon receipt and only after all principal amounts are current according to the terms of the contract. Management’s evaluation of the allowance for loan losses is inherently subjective as it requires material estimates. The actual amounts of loan losses realized in the near term could differ from the amounts estimated in arriving at the allowance for loan losses reported in the financial statements.
Commitments and Contingencies, Policy [Policy Text Block]	Reserve for Unfunded Commitments In addition to the allowance for loan losses, the Company has established a reserve for unfunded commitments, classified in other liabilities. This reserve is maintained at a level sufficient to absorb losses arising from unfunded loan commitments. The adequacy of the reserve for unfunded commitments is determined monthly based on methodology similar to the Company’s methodology for determining the allowance for loan losses. Net adjustments to the reserve for unfunded commitments are included in other non-interest expense.
Business Combinations Policy [Policy Text Block]	Acquisition Accounting, Acquired Loans The Company accounts for its acquisitions under ASC Topic 805, Business Combinations The Company evaluates loans acquired in accordance with the provisions of ASC Topic 310-20, Nonrefundable Fees and Other Costs Loans and Debt Securities Acquired with Deteriorated Credit Quality For impaired loans accounted for under ASC Topic 310-30, the Company continues to estimate cash flows expected to be collected on these loans. The Company evaluates at each balance sheet date whether the present value of the loans determined using the effective interest rates has decreased significantly and if so, recognize a provision for loan loss in our consolidated statement of income. For any significant increases in cash flows expected to be collected, the Company adjusts the amount of accretable yield recognized on a prospective basis over the remaining life of the loan.
Deteriorated Loans Transferred in, Policy [Policy Text Block]	Covered Loans and Related Indemnification Asset In September, we entered into an agreement with the FDIC to terminate all loss share agreements which were entered into in 2010 and 2012 in conjunction with the Company’s acquisition of substantially all of the assets (“covered assets”) and assumption of substantially all of the liabilities of four failed banks in FDIC-assisted transactions. Under the early termination, all rights and obligations of the Company and the FDIC under the FDIC loss share agreements, including the clawback provisions and the settlement of loss share and expense reimbursement claims, have been resolved and terminated. Under the terms of the agreement, the FDIC made a net payment of $2,368,000 to the bank as consideration for the early termination of the loss share agreements. The early termination was recorded in the Company’s financial statements by removing the FDIC Indemnification Asset, receivable from FDIC, the FDIC True-up liability and recording a one-time, pre-tax charge of $7,476,000. As a result, the Company reclassified loans previously covered by FDIC loss share to loans acquired, not covered by FDIC loss share. Foreclosed assets previously covered by FDIC loss share were reclassified to foreclosed assets not covered by FDIC loss share. For further discussion of our acquisition and loan accounting, see Note 2, Acquisitions, and Note 5, Loans Acquired.
Property, Plant and Equipment, Policy [Policy Text Block]	Premises and Equipment Depreciable assets are stated at cost less accumulated depreciation. Depreciation is charged to expense using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are capitalized and amortized by the straight-line method over the terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter.
Premises Held-for-sale Policy [Policy Text Block]	Premises Held for Sale The Company records premises held for sale at the lower of (1) cost less accumulated depreciation or (2) fair value less estimated selling expenses. These assets are assessed for impairment at the time they are reclassified as held for sale and periodically thereafter.
Real Estate Held for Development and Sale, Policy [Policy Text Block]	Foreclosed Assets Held For Sale Assets acquired by foreclosure or in settlement of debt and held for sale are valued at estimated fair value as of the date of foreclosure, and a related valuation allowance is provided for estimated costs to sell the assets. Management evaluates the value of foreclosed assets held for sale periodically and increases the valuation allowance for any subsequent declines in fair value. Changes in the valuation allowance are charged or credited to other expense.
Bank Owned Life Insurance, Policy [Policy Text Block}	Bank Owned Life Insurance The Company maintains bank-owned life insurance policies on certain current and former employees and directors, which are recorded at their cash surrender values as determined by the insurance carriers. The appreciation in the cash surrender value of the policies is recognized as a component of non-interest income in the Company’s consolidated statements of income.
Goodwill and Intangible Assets, Policy [Policy Text Block]	Goodwill and Intangible Assets Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. Other intangible assets represent purchased assets that also lack physical substance but can be separately distinguished from goodwill because of contractual or other legal rights or because the asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset or liability. The Company performs an annual goodwill impairment test, and more frequently if circumstances warrant, in accordance with ASC Topic 350, Intangibles – Goodwill and Other
Derivatives, Policy [Policy Text Block]	Derivative Financial Instruments The Company may enter into derivative contracts for the purposes of managing exposure to interest rate risk to meet the financing needs of its customers. The Company records all derivatives on the balance sheet at fair value. Historically, the Company’s policy has been not to invest in derivative type investments, but, in an effort to meet the financing needs of its customers, the Company has entered into limited fair value hedges. Fair value hedges include interest rate swap agreements on fixed rate loans. For derivatives designated as hedging the exposure to changes in the fair value of the hedged item, the gain or loss is recognized in earnings in the period of change together with the offsetting loss or gain of the hedging instrument. The fair value hedges are considered to be highly effective and any hedge ineffectiveness was deemed not material. The notional amount of the swaps was $61.3 million at December 31, 2015, and $14.6 million at December 31, 2014.
Repurchase and Resale Agreements Policy [Policy Text Block]	Securities Sold Under Agreements to Repurchase The Company sells securities under agreements to repurchase to meet customer needs for sweep accounts. At the point funds deposited by customers become investable, those funds are used to purchase securities owned by the Company and held in its general account with the designation of Customers’ Securities. A third party maintains control over the securities underlying overnight repurchase agreements. The securities involved in these transactions are generally U.S. Treasury or Federal Agency issues. Securities sold under agreements to repurchase generally mature on the banking day following that on which the investment was initially purchased and are treated as collateralized financing transactions which are recorded at the amounts at which the securities were sold plus accrued interest. Interest rates and maturity dates of the securities involved vary and are not intended to be matched with funds from customers.
Investment Banking Fees, Policy [Policy Text Block]	Bankcard Fee Income Periodic bankcard fees, net of direct origination costs, are recognized as revenue on a straight-line basis over the period the fee entitles the cardholder to use the card.
Income Tax, Policy [Policy Text Block]	Income Taxes The Company accounts for income taxes in accordance with income tax accounting guidance in ASC Topic 740, Income Taxes Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term more likely than not means a likelihood of more than 50 percent; the terms examined and upon examination also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances and information available at the reporting date and is subject to management’s judgment. Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized. The Company files consolidated income tax returns with its subsidiaries.
Earnings Per Share, Policy [Policy Text Block]	Earnings Per Share Basic earnings per share are computed based on the weighted average number of shares outstanding during each year. Diluted earnings per share are computed using the weighted average common shares and all potential dilutive common shares outstanding during the period. The computation of per share earnings is as follows: (In thousands, except per share data) 2015 2014 2013 Net income available to common shareholders $ 74,107 $ 35,688 $ 23,231 Average common shares outstanding 28,084 16,879 16,339 Average potential dilutive common shares 126 43 13 Average diluted common shares 28,210 16,922 16,352 Basic earnings per share $ 2.64 $ 2.11 $ 1.42 Diluted earnings per share $ 2.63 $ 2.11 $ 1.42 Stock options to purchase 84,780 shares for the year ended December 31, 2013 were not included in the earnings per share calculation because the exercise price exceeded the average market price. There were no such shares for the years ended December 31, 2015 and 2014.

Pursuant to the plans, shares are reserved for future issuance by the Company, upon exercise of stock options or awarding of bonus shares granted to directors, officers and other key employees.
