[1]	EPS are computed independently for each quarter and therefore the sum of each quarterly EPS may not equal the year-to-date EPS. As a result of the large stock issuances during 2015 as part of the Company's acquisitions, the computed independent quarterly average common shares outstanding and the computed year-to-date average common shares differ significantly. For purposes of calculating a roll-forward amount for year-to-date EPS, diluted EPS for the second quarter would require a computed amount of $0.71, producing a difference of $.04 from actual second quarter diluted EPS of $0.67. This difference is based on the direct result of the varying denominator for each period presented.

All loans acquired in the FDIC transactions, both covered and not covered, were deemed to be impaired loans. All loans acquired, whether or not covered by FDIC loss share agreements, 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. For impaired loans accounted for under ASC Topic 310-30, we continue to estimate cash flows expected to be collected on pools of loans sharing common risk characteristics, which are treated in the aggregate when applying various valuation techniques. We evaluate at each balance sheet date whether the present value of our pools of 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, we adjust the amount of accretable yield recognized on a prospective basis over the pool’s remaining life. Covered Loans and Related Indemnification Asset Because the FDIC will reimburse us for certain losses incurred on certain acquired loans, an indemnification asset is recorded at fair value at the acquisition date. The indemnification asset is recognized at the same time as the indemnified loans, and measured on the same basis, subject to collectability or contractual limitations. The shared-loss agreements on the acquisition date reflect the reimbursements expected to be received from the FDIC, using an appropriate discount rate, which reflects counterparty credit risk and other uncertainties. The shared-loss agreements continue to be measured on the same basis as the related indemnified loans, as prescribed by ASC Topic 805. Deterioration in the credit quality of the loans (immediately recorded as an adjustment to the allowance for loan losses) would immediately increase the basis of the shared-loss agreements, with the offset recorded through the consolidated statement of income. Increases in the credit quality or cash flows of loans (reflected as an adjustment to yield and accreted into income over the remaining life of the loans) decrease the basis of the shared-loss agreements, with such decrease being accreted into income over 1) the same period or 2) the life of the shared-loss agreements, whichever is shorter. Loss assumptions used in the basis of the indemnified loans are consistent with the loss assumptions used to measure the indemnification asset. Fair value accounting incorporates into the fair value of the indemnification asset an element of the time value of money, which is accreted back into income over the life of the shared-loss agreements. Upon the determination of an incurred loss the indemnification asset will be reduced by the amount owed by the FDIC. A corresponding, claim receivable is recorded until cash is received from the FDIC. For further discussion of the Company’s acquisition and loan accounting, see 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 and six months ended June 30, 2015 and 2014: Three Months Ended Six Months Ended (In thousands, except per share data) 2015 2014 2015 2014 Net income available to common shareholders $ 20,018 $ 9,908 $ 28,727 $ 14,261 Average common shares outstanding 29,867 16,318 26,084 16,294 Average potential dilutive common shares 120 43 120 43 Average diluted common shares 29,987 16,361 26,204 16,337 Basic earnings per share $ 0.67 $ 0.61 $ 1.10 $ 0.88 Diluted earnings per share (1) $ 0.67 $ 0.60 $ 1.10 $ 0.87 (1) EPS are computed independently for each quarter and therefore the sum of each quarterly EPS may not equal the year-to-date EPS. As a result of the large stock issuances during 2015 as part of the Company’s acquisitions, the computed independent quarterly average common shares outstanding and the computed year-to-date average common shares differ significantly. For purposes of calculating a roll-forward amount for year-to-date EPS, diluted EPS for the second quarter would require a computed amount of $0.71, producing a difference of $.04 from actual second quarter diluted EPS of $0.67. This difference is based on the direct result of the varying denominator for each period presented.

Mergers, Acquisitions and Dispositions Disclosures [Text Block]	NOTE 2: ACQUISITIONS Liberty Bancshares, Inc. On February 27, 2015, the 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”). Simmons 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 23 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 Bank on April 24, 2015. Goodwill of $95.6 million was recorded as a result of the transaction. The merger strengthened Simmons’ position in the southwest Missouri market and Simmons 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 (3,843 ) 13,860 Total assets acquired $ 1,061,567 $ 3,974 $ 1,065,541 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 (840 ) 19,780 Accrued interest and other liabilities 7,828 300 8,128 Total liabilities assumed 949,290 (317 ) 948,973 Equity 112,277 (112,277 ) - Total equity assumed 112,277 (112,277 ) - Total liabilities and equity assumed $ 1,061,567 $ (112,594 ) $ 948,973 Net assets acquired 116,568 Purchase price 212,176 Goodwill $ 95,608 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. Cash and due from banks, time deposits due from banks and federal funds sold Investment securities Loans acquired Premises and equipment Bank owned life insurance Goodwill Core deposit intangible Other assets Deposits FHLB borrowings Subordinated debentures Accrued interest and other liabilities The purchase price allocation and certain fair value measurements remain preliminary due to the timing of the acquisition and due to the number of assets acquired and liabilities assumed. Management will continue to review the estimated fair values of loans, property and equipment, intangible assets, subordinated debentures, and other assets and liabilities, and to evaluate the assumed tax positions. The Company expects to finalize its analysis of the acquired loans and subordinated debentures along with the other 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 Liberty subsequent to the acquisition date. Community First Bancshares, Inc. On February 27, 2015, the 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”). Simmons 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. Simmons 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 expects to complete the systems conversion and merge FSB into Simmons Bank by September 4, 2015. Goodwill of $111.3 million was recorded as a result of the transaction. The merger allowed Simmons’ entrance into the Tennessee market and will serve as a launching platform for possible expansion into adjacent areas. Simmons 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 Simmons 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 3,667 7,367 Other assets 11,474 - 11,474 Total assets acquired $ 1,918,325 $ (3,135 ) $ 1,915,190 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 1,347 144,394 Subordinated debentures 21,754 (510 ) 21,244 Accrued interest and other liabilities 8,769 601 9,370 Total liabilities assumed 1,725,013 2,287 1,727,300 Equity 193,312 (193,312 ) - Total equity assumed 193,312 (193,312 ) - Total liabilities and equity assumed $ 1,918,325 $ (191,025 ) $ 1,727,300 Net assets acquired 187,890 Purchase price 299,204 Goodwill $ 111,314 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.

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 Community First subsequent to the acquisition date. Summary of Unaudited Pro forma Information The unaudited pro forma information below for the three and six months ended June 30, 2015 and 2014 gives effect to the Liberty and Community First acquisitions as if the acquisitions had occurred on January 1, 2014. Pro forma earnings for the three months ended June 30, 2015 were adjusted to exclude $7.4 million of acquisition-related costs, net of tax, incurred by Simmons during 2015. Supplemental pro-forma earnings for the six months ended June 30, 2014 were also adjusted to include these charges. The pro forma financial information is not necessarily indicative of the results of operations if the acquisitions had been effective as of this date. (In thousands) Three Months Ended June 30, 2015 Three Months Ended June 30, 2014 Revenue (1) $ 96,942 $ 95,504 Net income $ 30,043 $ 9,934 Earnings per share $ 1.00 $ 0.35 (In thousands) Six Months Ended June 30, 2015 Six Months Ended June 30, 2014 Revenue (1) $ 194,203 $ 185,977 Net income $ 42,090 $ 26,191 Earnings per share $ 1.40 $ 0.93 (1) Net interest income plus noninterest income. Consolidated year-to-date 2015 results included approximately $18.8 million of revenue and $8.3 million of net income attributable to the Liberty acquisition and $32.5 million of revenue and $8.4 million of net income attributable to the Community First acquisition. Ozark Trust & Investment Corporation (Pending Acquisition) On April 28, 2015, the Company entered into a definitive agreement and plan of merger (the “Agreement”) with Ozark Trust & Investment Corporation (“OTIC”), including its wholly-owned non-deposit trust company, Trust Company of the Ozarks (“TCO”). TCO is headquartered in Springfield, Missouri and has over $1 billion in assets under management. Under the terms of the Agreement, each outstanding share of common stock of OTIC held by banks or bank holding companies will be converted into the right to receive $701.9268 in cash and each share of common stock or common stock equivalents held by any other type of shareholder will be converted into the right to receive 16.7205 shares of the Company’s common stock, all subject to certain conditions and potential adjustments. The Company owns 1,000 shares of OTIC’s common stock, which it acquired through its acquisition of Liberty Bancshares, Inc. in February 2015. The transaction is valued at $20.7 million (based on the Company’s April 27, 2015 closing price). The purchase price will be allocated among the net assets of OTIC acquired as appropriate, with the remaining balance being reported as goodwill. The transaction is subject to the routine regulatory review by the Missouri Department of Finance and other customary closing conditions. The transaction is expected to close during the third quarter of 2015. Upon closing, OTIC will merge into the Company.

Certain investment securities are valued at less than their historical cost. Total fair value of these investments at June 30, 2015, was $983.1 million, which is approximately 61.1% 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 June 30, 2015: Less Than 12 Months 12 Months or More Total (In thousands) Estimated Gross Estimated Gross Estimated Gross Held-to-Maturity U.S. Government agencies $ 177,586 $ (850 ) $ 63,880 $ (613 ) $ 241,466 $ (1,463 ) Mortgage-backed securities 8,581 (46 ) 8,882 (194 ) 17,463 (240 ) State and political subdivisions 191,420 (2,995 ) 3,805 (64 ) 195,225 (3,059 ) Total HTM $ 377,587 $ (3,891 ) $ 76,567 $ (871 ) $ 454,154 $ (4,762 ) Available-for-Sale U.S. Government agencies $ 138,848 $ (405 ) $ 42,673 $ (430 ) $ 181,521 $ (835 ) Mortgage-backed securities 342,210 (2,092 ) - - 342,210 (2,092 ) State and political subdivisions 3,473 (19 ) - - 3,473 (19 ) Equity Securities 764 (5 ) - - 764 (5 ) Other 1,000 (836 ) - - 1,000 (836 ) Total AFS $ 486,295 $ (3,357 ) $ 42,673 $ (430 ) $ 528,968 $ (3,787 ) 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 June 30, 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 June 30, 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. The book value of securities sold under agreements to repurchase equaled $105.7 million and $100.8 million for June 30, 2015 and December 31, 2014, respectively.

There were no realized gains and no realized losses for the three months ended June 30, 2015 and there were $2,000 of gross realized gains and $40,000 of realized losses from the sale of available for sale securities during the six months ended June 30, 2015. There were $38,000 of realized gains and no realized losses on investment securities for the three and six months ended June 30, 2014.

Allocations of the allowance for loan losses relative to impaired loans were $2.0 million at June 30, 2015 and $2.1 million at December 31, 2014. Approximately $300,000 and $549,000 of interest income was recognized on average impaired loans of $16.6 million and $16.0 million for the three and six months ended June 30, 2015. Interest income recognized on impaired loans on a cash basis during the three and six months ended June 30, 2015 and 2014 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 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, 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 six months ended June 30, 2015, the Company modified seven loans with a total recorded investment of $728,000 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 three months ended June 30, 2014, the Company modified one loan with a recorded investment of $599,000 and during the six months ended June 30, 2014, the Company modified two loans with a total recorded investment of $1,630,000 prior to modification which were deemed troubled debt restructuring. The restructured loans were modified by changing 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. There were no loans for which a payment default occurred during the six months ended June 30, 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 $4,756,500 and $9,268,321 at June 30, 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 June 30, 2015, the Company had $1,537,000 of consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceedings are in process. At June 30, 2015, the Company had $4,599,000 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, including loans covered by FDIC loss share agreements, are evaluated using this internal grading system. Loans acquired through FDIC-assisted transactions are accounted for in pools. All of the non-covered loan pools accounted for under ASC Topic 310-30 were considered satisfactory (Risk Ratings 1 – 4) at June 30, 2015 and December 31, 2014, respectively. Loans acquired in the Liberty, Community First, Metropolitan and Delta Trust acquisitions are evaluated individually and include purchased credit impaired loans of $32.9 million and $22.3 million that are accounted for under ASC Topic 310-30 and are classified as substandard (Risk Rating 6) as of June 30, 2015 and December 31, 2014, respectively. Of the remaining loans acquired in the Liberty, Community First, Metropolitan and Delta Trust transactions and accounted for under ASC Topic 310-20, $29.8 million and $16.6 million were classified (Risk Ratings 6, 7 and 8 – see classified loans discussion below) at June 30, 2015 and December 31, 2014, respectively. Loans acquired, covered by loss share agreements, have additional protection provided by the FDIC. During the 2014 quarterly impairment testing on the estimated cash flows of the credit impaired loans, the Company established that some of the pools covered by loss share from our FDIC-assisted transactions had experienced material projected credit deterioration. As a result, the Company established a $1.0 million 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 the period ended June 30, 2015. 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 covered and non-covered loans acquired in FDIC-assisted transactions, were $102.1 million and $82.1 million, as of June 30, 2015 and December 31, 2014, respectively.

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 three and six months ended June 30, 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 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. The Company evaluated all of the loans acquired during 2013 – 2014 using the same methodologies as in the 2015 acquisitions. The Company evaluated all of the loans purchased in conjunction with its previous FDIC-assisted transactions in accordance with the provisions of ASC Topic 310-30. All loans acquired in the FDIC transactions, both covered and not covered, were deemed to be impaired loans. All loans acquired, whether or not covered by FDIC loss share agreements, 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.

The loans acquired in FDIC assisted transactions were grouped into pools based on common risk characteristics and the pools were recorded at their estimated fair values, which incorporated estimated credit losses at the acquisition date. These loans and loan pools 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 non-covered loans acquired in the Liberty acquisition on February 27, 2015, as of the date of acquisition. (in thousands) Not Impaired Impaired Contractually required principal and interest at acquisition $ 774,777 $ 15,716 Non-accretable difference (expected losses and foregone interest) - (4,978 ) Cash flows expected to be collected at acquisition 774,777 10,738 Accretable yield (4,869 ) 12 Basis in acquired loans at acquisition $ 769,908 $ 10,750 The following is a summary of the non-covered loans acquired in the Community First acquisition on February 27, 2015, as of the date of acquisition. (in thousands) Not Impaired Impaired Contractually required principal and interest at acquisition $ 1,153,255 $ 10,143 Non-accretable difference (expected losses and foregone interest) - (3,247 ) Cash flows expected to be collected at acquisition 1,153,255 6,896 Accretable yield (23,712 ) 104 Basis in acquired loans at acquisition $ 1,129,543 $ 7,000 The amount of the estimated cash flows expected to be received from the acquired loan pools and purchased credit impaired loans in excess of the fair values recorded for the loan pools and 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 loan pools and 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 or loan pools. For those loan pools covered by FDIC loss share, the increases in expected cash flows also reduce the amount of expected reimbursements under the loss sharing agreements with the FDIC, which are recorded as indemnification assets. The estimated adjustments to the indemnification assets are amortized on a level-yield basis over the remainder of the loss sharing agreements or the remaining expected lives of the loan pools, whichever is shorter. The impact of the adjustments on the Company’s financial results for the three and six months ended June 30, 2015 and 2014 is shown below: Three Months Ended Six Months Ended (In thousands) 2015 2014 2015 2014 Impact on net interest income $ 3,223 $ 5,856 $ 9,325 $ 13,247 Non-interest income (2,941 ) (6,410 ) (5,686 ) (13,850 ) Net impact to pre-tax income 282 (554 ) 3,639 (603 ) Net impact, net of taxes $ 171 $ (337 ) $ 2,212 $ (366 ) These adjustments will be recognized over the remaining lives of the loans for purchased credit impaired loans. For FDIC acquisition loans, the adjustments will be recognized over the remaining lives of the loan pools and, for covered loans, over the remainder of the loss sharing agreements, respectively. The current estimate of the remaining accretable yield adjustment that will positively impact interest income is $15.3 million and the remaining adjustment to the indemnification assets that will reduce non-interest income is $6.6 million. Of the remaining adjustments, the Company expects to recognize $5.8 million of interest income and a $5.4 million reduction of non-interest income, for a net increase to pre-tax income of approximately $0.4 million during the remainder of 2015. The accretable yield adjustments recorded in future periods will change as the Company continues to evaluate expected cash flows from the acquired loan pools and purchased credit impaired loans. Changes in the carrying amount of the accretable yield for all purchased impaired loans were as follows for the three and six months ended June 30, 2015 and 2014.

Because some pools evaluated by the Company, 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 $1.0 million allowance for loan losses for covered purchased impaired loans. For Liberty, Community First, Metropolitan and Delta Trust, purchased impaired loans are evaluated on an individual borrower basis. No loans, not covered by loss share, evaluated by the Company were determined to have experienced further impairment. Therefore, there were no allowances for loan losses related to the non-covered purchased impaired loans at June 30, 2015 or December 31, 2014. The purchase and assumption agreements for the FDIC-assisted acquisitions allow for the FDIC to recover a portion of the funds previously paid out under the indemnification agreement in the event losses fail to reach the expected loss level under a claw back provision (“true-up provision”). The amount of the true-up provision for each acquisition is measured and recorded at Day 1 fair values. It is 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. This true-up amount, which is payable to the FDIC upon termination of the applicable loss share agreement, is then discounted back to net present value. To the extent that actual losses on covered loans and covered foreclosed assets are less than estimated losses, the applicable true-up provision payable to the FDIC upon termination of the loss share agreements will increase. To the extent that actual losses on covered loans and covered foreclosed assets are more than estimated losses, the applicable true-up provision payable to the FDIC upon termination of the loss share agreements will decrease. The following table presents a summary of the changes in the FDIC true-up provision for the three and six months ended June 30, 2015 and 2014.

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 $314.2 million at June 30, 2015 and $108.1 million at December 31, 2014. The Company recorded $111.3 million and $95.6 of goodwill during the six months ended June 30, 2015 as a result of its acquisitions of Community First and Liberty, respectively. Goodwill impairment was neither indicated nor recorded during the six months ended June 30, 2015 or the year ended December 31, 2014. 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. The Delta Trust acquisition on August 31, 2014 included some significant lines of business related to investments, trust and insurance, for which the Company recorded $5.1 million of intangible assets. The Company also recorded $0.4 million of intangible assets during the six months ended June 30, 2015 related to a line of insurance business as part of the Community First acquisition. These intangible assets are being amortized over various periods ranging from 10 to 15 years. On September 30, 2013, the Company acquired a credit card portfolio and recorded Purchased Credit Card Relationships (“PCCR’s”) of $2.1 million. This intangible asset is being amortized over a five year period.

Capital Stock Disclosure [Text Block]	NOTE 12: COMMON STOCK During 2012, the Company announced the adoption by the Board of Directors of a new stock repurchase program. The program authorizes the repurchase of up to 850,000 additional 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 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.

Disclosure Text Block Supplement [Abstract]
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 June 30, 2015, the Company had outstanding commitments to extend credit aggregating approximately $495,558,000 and $783,710,000 for credit card commitments and other loan commitments. 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. 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 $26,711,000 and $16,217,000 at June 30, 2015, and December 31, 2014, respectively, with terms ranging from 9 months to 15 years. At June 30, 2015, the Company had no deferred revenue under standby letter of credit agreements and approximately $13,000 at December 31, 2014.

Fair Value Disclosures [Abstract]
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. There have been no significant changes in valuation techniques during the periods ended June 30, 2015 and 2014. Available-for-sale securities Assets held in trading accounts The following table sets forth the Company’s financial assets and liabilities by level within the fair value hierarchy that were measured at fair value on a recurring basis as of June 30, 2015 and December 31, 2014. Fair Value Measurements Using (In thousands) Fair Value Quoted Prices in Significant Other Significant June 30, 2015 ASSETS Available-for-sale securities U.S. Treasury $ 4,005 $ - $ 4,005 $ - U.S. Government agencies 236,003 - 236,003 - Mortgage-backed securities 464,857 - 464,857 - State and political subdivisions 10,971 - 10,971 - Other securities 31,865 - 31,865 - Assets held in trading accounts 6,481 2,709 3,772 - 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 - State 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. 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 June 30, 2015 and December 31, 2014.

ASC Topic 825, Financial Instruments Cash and cash equivalents and interest bearing balances due from banks – time Held-to-maturity securities Loans Loans acquired FDIC indemnification asset Deposits Federal Funds purchased, securities sold under agreement to repurchase 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.

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 in accordance with the provisions of ASC Topic 310-20, Nonrefundable Fees and Other Costs Loans and Debt Securities Acquired with Deteriorated Credit Quality The Company evaluates all of the loans purchased in conjunction with its FDIC-assisted transactions in accordance with the provisions of ASC Topic 310-30. All loans acquired in the FDIC transactions, both covered and not covered, were deemed to be impaired loans. All loans acquired, whether or not covered by FDIC loss share agreements, 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. For impaired loans accounted for under ASC Topic 310-30, we continue to estimate cash flows expected to be collected on pools of loans sharing common risk characteristics, which are treated in the aggregate when applying various valuation techniques. We evaluate at each balance sheet date whether the present value of our pools of 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, we adjust the amount of accretable yield recognized on a prospective basis over the pool’s remaining life.
Deteriorated Loans Transferred in, Policy [Policy Text Block]	Covered Loans and Related Indemnification Asset Because the FDIC will reimburse us for certain losses incurred on certain acquired loans, an indemnification asset is recorded at fair value at the acquisition date. The indemnification asset is recognized at the same time as the indemnified loans, and measured on the same basis, subject to collectability or contractual limitations. The shared-loss agreements on the acquisition date reflect the reimbursements expected to be received from the FDIC, using an appropriate discount rate, which reflects counterparty credit risk and other uncertainties. The shared-loss agreements continue to be measured on the same basis as the related indemnified loans, as prescribed by ASC Topic 805. Deterioration in the credit quality of the loans (immediately recorded as an adjustment to the allowance for loan losses) would immediately increase the basis of the shared-loss agreements, with the offset recorded through the consolidated statement of income. Increases in the credit quality or cash flows of loans (reflected as an adjustment to yield and accreted into income over the remaining life of the loans) decrease the basis of the shared-loss agreements, with such decrease being accreted into income over 1) the same period or 2) the life of the shared-loss agreements, whichever is shorter. Loss assumptions used in the basis of the indemnified loans are consistent with the loss assumptions used to measure the indemnification asset. Fair value accounting incorporates into the fair value of the indemnification asset an element of the time value of money, which is accreted back into income over the life of the shared-loss agreements. Upon the determination of an incurred loss the indemnification asset will be reduced by the amount owed by the FDIC. A corresponding, claim receivable is recorded until cash is received from the FDIC. For further discussion of the Company’s acquisition and loan accounting, see 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 and six months ended June 30, 2015 and 2014: Three Months Ended Six Months Ended (In thousands, except per share data) 2015 2014 2015 2014 Net income available to common shareholders $ 20,018 $ 9,908 $ 28,727 $ 14,261 Average common shares outstanding 29,867 16,318 26,084 16,294 Average potential dilutive common shares 120 43 120 43 Average diluted common shares 29,987 16,361 26,204 16,337 Basic earnings per share $ 0.67 $ 0.61 $ 1.10 $ 0.88 Diluted earnings per share (1) $ 0.67 $ 0.60 $ 1.10 $ 0.87 (1) EPS are computed independently for each quarter and therefore the sum of each quarterly EPS may not equal the year-to-date EPS. As a result of the large stock issuances during 2015 as part of the Company’s acquisitions, the computed independent quarterly average common shares outstanding and the computed year-to-date average common shares differ significantly. For purposes of calculating a roll-forward amount for year-to-date EPS, diluted EPS for the second quarter would require a computed amount of $0.71, producing a difference of $.04 from actual second quarter diluted EPS of $0.67. This difference is based on the direct result of the varying denominator for each period presented.

[1]	EPS are computed independently for each quarter and therefore the sum of each quarterly EPS may not equal the year-to-date EPS. As a result of the large stock issuances during 2015 as part of the Company's acquisitions, the computed independent quarterly average common shares outstanding and the computed year-to-date average common shares differ significantly. For purposes of calculating a roll-forward amount for year-to-date EPS, diluted EPS for the second quarter would require a computed amount of $0.71, producing a difference of $.04 from actual second quarter diluted EPS of $0.67. This difference is based on the direct result of the varying denominator for each period presented.
