Notes to Financial Statements
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	NOTE 1: BASIS OF PRESENTATION The consolidated financial statements include the accounts of Simmons First National Corporation (the “Company”) and its subsidiaries. Significant intercompany accounts and transactions have been eliminated in consolidation. All adjustments made to the unaudited financial statements were of a normal recurring nature. In the opinion of management, all adjustments necessary for a fair presentation of the results of interim periods have been made. Certain prior year amounts are reclassified to conform to current year classification. The consolidated balance sheet of the Company as of December 31, 2015, has been derived from the audited consolidated balance sheet of the Company as of that date. The results of operations for the period are not necessarily indicative of the results to be expected for the full year. Certain information and note disclosures normally included in the Company’s annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted. These consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Form 10-K Annual Report for 2015 filed with the U.S. Securities and Exchange Commission (the “SEC”). Recently Issued Accounting Pronouncements ASU 2016-02 – Leases ASU 2016-09 – Compensation-Stock Compensation: Improvements to Employee Share-Based Payment Accounting ASU 2016-01 – Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities ASU 2015-16 – Business Combinations: Simplifying the Accounting for Measurement-Period Adjustments ASU 2015-14 – Revenue from Contracts with Customers: Deferral of the Effective Date ASU 2015-08 – Business Combinations: Pushdown Accounting – Amendments to SEC Paragraphs Pursuant to Staff Accounting Bulletin No. 115 ASU 2015-02 – Consolidation (Topic 810): Amendments to the Consolidation Analysis There have been no other significant changes to the Company’s accounting policies from the 2015 Form 10-K. Presently, the Company is not aware of any other changes to the Accounting Standards Codification that will have a material impact on the Company’s present or future financial position or results of operations. Acquisition Accounting, Acquired Loans The Company accounts for its acquisitions under ASC Topic 805, Business Combinations The Company evaluates loans acquired, other than purchased impaired loans, 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 2015, 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. Earnings Per Common Share (“EPS”) Basic EPS is computed by dividing reported net income available to common shareholders by weighted average number of common shares outstanding during each period. Diluted EPS is computed by dividing reported net income available to common shareholders by the weighted average common shares and all potential dilutive common shares outstanding during the period. Following is the computation of earnings per common share for the three months ended March 31, 2016 and 2015: (In thousands, except per share data) 2016 2015 Net income available to common shareholders $ 23,481 $ 8,709 Average common shares outstanding 30,326 22,258 Average potential dilutive common shares 156 92 Average diluted common shares 30,482 22,350 Basic earnings per common share $ 0.77 $ 0.39 Diluted earnings per common share $ 0.77 $ 0.39

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.

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 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 is able to achieve cost savings by integrating the two companies and combining accounting, data processing, and other administrative functions. Further the Company 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.

The Company’s operating results for 2015 include the operating results of the acquired assets and assumed liabilities of Community First subsequent to the acquisition date. 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 – The carrying amount of these assets was deemed to be a reasonable estimate of fair value. 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.

Certain investment securities are valued at less than their historical cost. Total fair value of these investments at March 31, 2016, was $273.7 million, which is approximately 17.9% of the Company’s combined available-for-sale and held-to-maturity investment portfolios. The following table shows the gross unrealized losses and fair value of the Company’s investments with unrealized losses, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position at March 31, 2016: Less Than 12 Months 12 Months or More Total (In thousands) Estimated Gross Estimated Gross Estimated Gross Held-to-Maturity U.S. Government agencies $ 73,941 $ (46 ) $ 53,958 $ (43 ) $ 127,899 $ (89 ) Mortgage-backed securities 1,375 (3 ) 9,184 (36 ) 10,559 (39 ) State and political subdivisions 6,143 (10 ) 1,873 (5 ) 8,016 (15 ) Total HTM $ 81,459 $ (59 ) $ 65,015 $ (84 ) $ 146,474 $ (143 ) Available-for-Sale U.S. Government agencies $ 31,469 $ (25 ) $ 20,284 $ (16 ) $ 51,753 $ (41 ) Mortgage-backed securities 57,467 (98 ) 15,891 (5 ) 73,358 (103 ) State and political subdivisions 2,084 (11 ) -- -- 2,084 (11 ) Other securities 60 (21 ) -- -- 60 (21 ) Total AFS $ 91,080 $ (155 ) $ 36,175 $ (21 ) $ 127,255 $ (176 ) These declines primarily resulted from the rate for these investments yielding less than current market rates. 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 March 31, 2016, 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 March 31, 2016, 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. The book value of securities sold under agreements to repurchase equaled $86.9 million and $96.8 million for March 31, 2016 and December 31, 2015, respectively. Income earned on securities for the three months ended March 31, 2016 and 2015, is as follows: (In thousands) 2016 2015 Taxable: Held-to-maturity $ 876 $ 1,389 Available-for-sale 4,434 1,583 Non-taxable: Held-to-maturity 3,146 2,602 Available-for-sale 50 305 Total $ 8,506 $ 5,879 Maturities of investment securities at March 31, 2016, are as follows: Held-to-Maturity Available-for-Sale (In thousands) Amortized Fair Amortized Fair One year or less $ 39,343 $ 39,400 $ 19,592 $ 19,589 After one through five years 291,884 293,315 60,426 60,411 After five through ten years 119,343 122,356 7,754 7,983 After ten years 200,198 207,741 7,578 7,659 Securities not due on a single maturity date 23,734 24,023 715,097 722,982 Other securities (no maturity) -- -- 38,467 39,049 Total $ 674,502 $ 686,835 $ 848,914 $ 857,673 The carrying value, which approximates the fair value, of securities pledged as collateral, to secure public deposits and for other purposes, amounted to $963.4 million at March 31, 2016 and $840.4 million at December 31, 2015. There were $329,000 of gross realized gains and no realized losses from the sale of available for sale securities during the three months ended March 31, 2016. There were $2,000 of gross realized gains and $40,000 of realized losses from the sale of available for sale securities during the three months ended March 31, 2015. The state and political subdivision debt obligations are primarily non-rated bonds representing small, Arkansas, Illinois, Kansas, Missouri, Tennessee and Texas issues, which are evaluated on an ongoing basis.

Loan Origination/Risk Management – The Company seeks to manage its credit risk by diversifying its loan portfolio, determining that borrowers have adequate sources of cash flow for loan repayment without liquidation of collateral; obtaining and monitoring collateral; providing an adequate allowance for loans losses by regularly reviewing loans through the internal loan review process. The loan portfolio is diversified by borrower, purpose and industry. The Company seeks to use diversification within the loan portfolio to reduce its credit risk, thereby minimizing the adverse impact on the portfolio, if weaknesses develop in either the economy or a particular segment of borrowers. Collateral requirements are based on credit assessments of borrowers and may be used to recover the debt in case of default. Furthermore, a factor that influenced the Company’s judgment regarding the allowance for loan losses consists of a five-year historical loss average segregated by each primary loan sector. On an annual basis, historical loss rates are calculated for each sector.

Allocations of the allowance for loan losses relative to impaired loans were $2.9 million and $2.8 million at March 31, 2016 and December 31, 2015, respectively. Approximately $351,000 of interest income was recognized on average impaired loans of $26.0 million for the three months ended March 31, 2016. Interest income recognized on impaired loans on a cash basis during the three months ended March 31, 2016 and 2015 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.

Based on the fair value of the collateral, a specific reserve of $293,000 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 the three months ended March 31, 2015, the Company modified two loans with a recorded investment of $348,000 prior to modification which was deemed troubled debt restructuring. The restructured loans were modified by deferring amortized principal payments and requiring interest only payments for a period of 12 months. Based on the fair value of the collateral, no specific reserve was determined necessary for this loan. Also, there was no immediate financial impact from the restructuring of this loan, as it was not considered necessary to charge-off interest or principal on the date of restructure. There were no loans for which a payment default occurred during the three months ended March 31, 2016 and 2015, 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 $166,500 and $4.8 million at March 31, 2016 and 2015, 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 March 31, 2016, the Company had $2,908,000 of consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceedings are in process. At March 31, 2016, the Company had $5,674,000 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 $21.3 million and $23.5 million that are accounted for under ASC Topic 310-30 and are classified as substandard (Risk Rating 6) as of March 31, 2016 and December 31, 2015, respectively. Of the remaining loans acquired and accounted for under ASC Topic 310-20, $47.9 million and $49.9 million were classified (Risk Ratings 6, 7 and 8 – see classified loans discussion below) at March 31, 2016 and December 31, 2015, 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 during 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 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 $164.5 million and $153.7 million, as of March 31, 2016 and December 31, 2015, respectively. The following table presents a summary of loans by credit risk rating as of March 31, 2016 and December 31, 2015, 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 by portfolio segment for the three months ended March 31, 2016. 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 [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.

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 amount of the estimated cash flows expected to be received from the purchased credit impaired loans in excess of the fair values recorded for the purchased credit impaired loans is referred to as the accretable yield. 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 three months ended March 31, 2016 and 2015 is shown below: Three Months Ended (In thousands) 2016 2015 Impact on net interest income $ 1,095 $ 6,102 Non-interest income (1) -- (2,745 ) Net impact to pre-tax income 1,095 3,357 Net impact, net of taxes $ 665 $ 2,040 ______________________________________________________________ (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 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 three months ended March 31, 2016 and 2015.

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 March 31, 2016 and 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. Due to the termination of the FDIC agreements in September 2015 there was no amortization expense recorded for the three months ended March 31, 2016. For the three months ended March 31, 2015, amortization expense of $40,000 and an adjustment related to changes in expected losses of $254,000 was recorded.

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 March 31, 2016 and December 31, 2015. Goodwill impairment was neither indicated nor recorded during the three months ended March 31, 2016 or the year ended December 31, 2015. 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 during the first quarter of 2015 as part of the Community First and Liberty acquisitions, respectively. Intangible assets are being amortized over various periods ranging from 10 to 15 years. The Community First acquisition on February 27, 2016 included an insurance line of business and the Company recorded an intangible asset of $420,000 during the first quarter of 2015.

The Company had total FHLB advances of $125.6 million at March 31, 2016, with approximately $985.9 million of additional advances available from the FHLB. The FHLB advances are secured by mortgage loans and investment securities totaling approximately $1.089 billion at March 31, 2016. 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. Each trust’s ability to pay amounts due on the trust preferred securities is solely dependent upon the Company making payment on the related junior subordinated debentures.

Capital Stock Disclosure [Text Block]	NOTE 12: COMMON STOCK During 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 at that time. 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. The Company suspended its stock repurchases in August of 2013, with 154,136 shares remaining available for repurchase under the program. 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.

Restrictions on Dividends, Loans and Advances [Text Block]	NOTE 13: UNDIVIDED PROFITS 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 Commissioner of the Arkansas State Bank Department is required, if the total of all dividends declared by an Arkansas state bank in any calendar year exceeds seventy-five percent (75%) of the total of its net profits, as defined, for that year combined with seventy-five percent (75%) of its retained net profits of the preceding year. At March 31, 2016, the Company’s subsidiary bank had approximately $4.4 million available for payment of dividends to the Company, without prior regulatory approval. The risk-based capital guidelines of the Federal Reserve Board and the Arkansas State Bank Department include the definitions for (1) a well-capitalized institution, (2) an adequately-capitalized institution, and (3) an undercapitalized institution. Under the newly adopted Basel III Rules, the criteria for a well-capitalized institution are: a 5% "Tier l leverage capital" ratio, an 8% "Tier 1 risk-based capital" ratio, 10% "total risk-based capital" ratio; and a 6.50% “common equity Tier 1 (CET1)” ratio. The Company and Bank must hold a capital conservation buffer composed of CET1 capital above its minimum risk-based capital requirements. The implementation of the capital conservation buffer began on January 1, 2016, at the 0.625% level and will phase in over a four-year period (increasing by that amount on each subsequent January 1 until it reaches 2.5% on January 1, 2019). As of March 31, 2016, the Company and its subsidiary bank met all capital adequacy requirements under the Basel III Capital Rules, and management believes the Company and subsidiary bank would meet all Capital Rules on a fully phased-in basis if such requirements were currently effective. The Company's CET1 ratio was 13.85% at March 31, 2016.

Stock-based compensation expense is recognized ratably over the requisite service period for all stock-based awards. There was $1,799,000 of unrecognized stock-based compensation expense related to stock options at March 31, 2016. Unrecognized stock-based compensation expense related to non-vested stock awards was $4,885,000 at March 31, 2016. At such date, the weighted-average period over which this unrecognized expense is expected to be recognized was 3.2 years. The intrinsic value of stock options outstanding and stock options exercisable at March 31, 2016 was $2,050,000 and $1,870,000. Aggregate intrinsic value represents the difference between the Company’s closing stock price on the last trading day of the period, which was $45.07 as of March 31, 2016, and the exercise price multiplied by the number of options outstanding and exercisable at a price below that closing price. The total intrinsic value of stock options exercised during the three months ended March 31, 2016 and March 31, 2015, was $220,000 and $193,000, respectively. 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 three months ended March 31, 2016 and March 31, 2015 was $11.64 and $8.81 per share, respectively. 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: Three Months Ended Three Months Ended Expected dividend yield 1.96 % 2.15 % Expected stock price volatility 27.34 % 21.08 % Risk-free interest rate 2.01 % 2.01 % Expected life of options (in years) 7 10

Commitments Disclosure [Text Block]	NOTE 18: COMMITMENTS AND CREDIT RISK The Company grants agri-business, commercial and residential loans to customers throughout Arkansas, Kansas, Missouri and Tennessee, along with credit card loans to customers throughout the United States. 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 March 31, 2016, the Company had outstanding commitments to extend credit aggregating approximately $630,888,000 and $903,999,000 for credit card commitments and other loan commitments. 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. 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 $26,823,000 and $23,515,000 at March 31, 2016, and December 31, 2015, respectively, with terms ranging from 9 months to 15 years.

Fair Value Disclosures [Text Block]	NOTE 20: FAIR VALUE MEASUREMENTS 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 March 31, 2016 and December 31, 2015. Fair Value Measurements Using (In thousands) Fair Value Quoted Prices in Significant Other Significant March 31, 2016 ASSETS Available-for-sale securities U.S. Treasury $ 4,302 $ 4,302 $ -- $ -- U.S. Government agencies 78,308 -- 78,308 -- Mortgage-backed securities 722,982 -- 722,982 -- State and political subdivisions 11,260 -- 11,260 -- Other securities 40,821 -- 40,821 -- Assets held in trading accounts 7,074 2,109 4,965 -- 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 -- 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. Management’s 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 March 31, 2016 and December 31, 2015.

(2) Specific allocations of $2,350,000 and $1,136,000 were related to the impaired collateral dependent loans for which fair value re-measurements took place during the periods ended March 31, 2016 and December 31, 2015, respectively. ASC Topic 825, Financial Instruments Cash and cash equivalents Interest bearing balances due from banks Held-to-maturity securities Loans Loans acquired 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 are as follows: Carrying Fair Value Measurements (In thousands) Amount Level 1 Level 2 Level 3 Total March 31, 2016 Financial assets: Cash and cash equivalents $ 223,061 $ 223,061 $ -- $ -- $ 223,061 Interest bearing balances due from banks - time 11,188 -- 11,188 -- 11,188 Held-to-maturity securities 674,502 -- 686,835 -- 686,835 Mortgage loans held for sale 24,563 -- -- 24,563 24,563 Interest receivable 23,545 -- 23,545 -- 23,545 Legacy loans (net of allowance) 3,440,010 -- -- 3,427,771 3,427,771 Loans acquired (net of allowance) 1,457,370 -- -- 1,452,185 1,452,185 Financial liabilities: Non-interest bearing transaction accounts 1,274,816 -- 1,274,816 -- 1,274,816 Interest bearing transaction accounts and savings deposits 3,524,808 -- 3,524,808 -- 3,524,808 Time deposits 1,280,151 -- -- 1,277,555 1,277,555 Federal funds purchased and securities sold under agreements to repurchase 97,429 -- 97,429 -- 97,429 Other borrowings 176,829 -- 196,668 -- 196,668 Subordinated debentures 60,077 -- 54,803 -- 54,803 Interest payable 1,864 -- 1,864 -- 1,864 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 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.

Presently, the Company is not aware of any other changes to the Accounting Standards Codification that will have a material impact on the Company’s present or future financial position or results of operations.
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, other than purchased impaired loans, 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 2015, 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.
Earnings Per Share, Policy [Policy Text Block]	Earnings Per Common Share (“EPS”) Basic EPS is computed by dividing reported net income available to common shareholders by weighted average number of common shares outstanding during each period. Diluted EPS is computed by dividing reported net income available to common shareholders by the weighted average common shares and all potential dilutive common shares outstanding during the period. Following is the computation of earnings per common share for the three months ended March 31, 2016 and 2015: (In thousands, except per share data) 2016 2015 Net income available to common shareholders $ 23,481 $ 8,709 Average common shares outstanding 30,326 22,258 Average potential dilutive common shares 156 92 Average diluted common shares 30,482 22,350 Basic earnings per common share $ 0.77 $ 0.39 Diluted earnings per common share $ 0.77 $ 0.39
