[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 2015 year-to-date EPS, diluted EPS for the second quarter of 2015 would require a computed amount of $0.74, producing a difference of $.02 from actual third quarter 2015 diluted EPS of $0.72. This difference is based on the direct result of the varying denominator for each period presented.
[2]	Stock options to purchase 61,395 and 326,565 shares for the three and nine months ended September 30, 2016 and 2015, respectively, were not included in the diluted EPS calculation because the exercise price of those options exceeded the average market price.

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”).

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 and nine months ended September 30, 2016 and 2015: Three Months Ended Nine Months Ended (In thousands, except per share data) 2016 2015 2016 2015 Net income available to common shareholders $ 23,429 $ 21,598 $ 69,819 $ 50,325 Average common shares outstanding 30,621 29,927 30,434 27,379 Average potential dilutive common shares 223 119 223 119 Average diluted common shares 30,844 30,046 30,657 27,498 Basic earnings per share $ 0.77 $ 0.72 $ 2.29 $ 1.84 Diluted earnings per share (1) (2) $ 0.76 $ 0.72 $ 2.28 $ 1.83 ______________________________ (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 2015 year-to-date EPS, diluted EPS for the third quarter of 2015 would require a computed amount of $0.74, producing a difference of $.02 from actual third quarter 2015 diluted EPS of $0.72. This difference is based on the direct result of the varying denominator for each period presented. (2) Stock options to purchase 61,395 and 326,565 shares for the three and nine months ended September 30, 2016 and 2015, respectively, were not included in the diluted EPS calculation because the exercise price of those options exceeded the average market price.

Mergers, Acquisitions and Dispositions Disclosures [Text Block]	NOTE 2: ACQUISITIONS Liberty Bancshares, Inc. On February 27, 2015, Simmons First National Corporation completed the acquisition of Liberty Bancshares, Inc. (“Liberty”), headquartered in Springfield, Missouri, including its wholly-owned bank subsidiary Liberty Bank (“LB”). The Company issued 5,181,337 shares of its common stock valued at approximately $212.2 million as of February 27, 2015 in exchange for all outstanding shares of Liberty common stock. Prior to the acquisition, Liberty conducted banking business from 24 branches located in southwest Missouri. Including the effects of the acquisition method accounting adjustments, the Company acquired approximately $1.1 billion in assets, including approximately $780.7 million in loans (inclusive of loan discounts) and approximately $874.7 million in deposits. The Company completed the systems conversion and merged LB into Simmons First National Bank on April 24, 2015. Goodwill of $95.2 million was recorded as a result of the transaction. The merger strengthened the Company’s position in the southwest Missouri market and the Company is 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 is not deductible for tax purposes. A summary, at fair value, of the assets acquired and liabilities assumed in the Liberty transaction, as of the acquisition date, is as follows: (In thousands) Acquired from Fair Value Fair Assets Acquired Cash and due from banks, including time deposits $ 102,637 $ (14 ) $ 102,623 Federal funds sold 7,060 -- 7,060 Investment securities 99,123 (335 ) 98,788 Loans acquired, not covered by FDIC loss share 790,493 (9,835 ) 780,658 Allowance for loan losses (10,422 ) 10,422 -- Premises and equipment 34,239 (3,215 ) 31,024 Bank owned life insurance 16,972 -- 16,972 Core deposit intangible 699 13,857 14,556 Other intangibles 3,063 (3,063 ) -- Other assets 17,703 (3,112 ) 14,591 Total assets acquired $ 1,061,567 $ 4,705 $ 1,066,272 Liabilities Assumed Deposits: Non-interest bearing transaction accounts $ 146,618 $ -- $ 146,618 Interest bearing transaction accounts and savings deposits 543,183 -- 543,183 Time deposits 184,913 -- 184,913 Total deposits 874,714 -- 874,714 FHLB borrowings 46,128 223 46,351 Subordinated debentures 20,620 (510 ) 20,110 Accrued interest and other liabilities 7,828 300 8,128 Total liabilities assumed 949,290 13 949,303 Equity 112,277 (112,277 ) -- Total equity assumed 112,277 (112,277 ) -- Total liabilities and equity assumed $ 1,061,567 $ (112,264 ) $ 949,303 Net assets acquired 116,969 Purchase price 212,176 Goodwill $ 95,207 During 2015 the Company finalized its analysis of the acquired loans and subordinated debentures along with the other acquired assets and assumed liabilities. The Company’s operating results for 2015 include the operating results of the acquired assets and assumed liabilities of Liberty subsequent to the acquisition date. Community First Bancshares, Inc. On February 27, 2015, Simmons First National Corporation completed the acquisition of Community First Bancshares, Inc. (“Community First”), headquartered in Union City, Tennessee, including its wholly-owned bank subsidiary First State Bank (“FSB”). The Company issued 6,552,915 shares of its common stock valued at approximately $268.3 million as of February 27, 2015, plus $9,974 in cash in exchange for all outstanding shares of Community First common stock. The Company also issued $30.9 million of preferred stock in exchange for all outstanding shares of Community First preferred stock. On January 29, 2016, the Company redeemed all of the preferred stock, including accrued and unpaid dividends. Prior to the acquisition, Community First conducted banking business from 33 branches located across Tennessee. Including the effects of the acquisition method accounting adjustments, the Company acquired approximately $1.9 billion in assets, including approximately $1.1 billion in loans (inclusive of loan discounts) and approximately $1.5 billion in deposits. The Company completed the systems conversion and merged FSB into Simmons First National 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 served 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 will 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 is not 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 During 2015 the Company finalized its analysis of the acquired loans and subordinated debentures along with the other acquired assets and assumed liabilities.

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.

Including the effects of the acquisition method accounting adjustments, the Company acquired approximately $585.2 million in assets, including approximately $340.8 million in loans (inclusive of loan discounts) and approximately $509.9 million in deposits. The Company completed the systems conversion and merged Citizens into Simmons Bank on October 21, 2016. Goodwill of $21.8 million was recorded as a result of the transaction.

Certain investment securities are valued at less than their historical cost. Total fair value of these investments at September 30, 2016, was $339.7 million, which is approximately 22.3% 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 September 30, 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 $ 30,987 $ (13 ) $ 19,972 $ (28 ) $ 50,959 $ (41 ) Mortgage-backed securities 339 (1 ) 1,618 (11 ) 1,957 (12 ) State and political subdivisions 14,982 (21 ) 330 (1 ) 15,312 (22 ) Total HTM $ 46,308 $ (35 ) $ 21,920 $ (40 ) $ 68,228 $ (75 ) Available-for-Sale U.S. Government agencies $ 102,360 $ (133 ) $ -- $ -- $ 102,360 $ (133 ) Mortgage-backed securities 134,133 (485 ) 134,133 (485 ) State and political subdivisions 34,900 (529 ) -- -- 34,900 (529 ) Other securities -- -- 60 (15 ) 60 (15 ) Total AFS $ 271,393 $ (1,147 ) $ 60 $ (15 ) $ 271,453 $ (1,162 ) 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 September 30, 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 September 30, 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 $123.8 million and $96.8 million for September 30, 2016 and December 31, 2015, respectively.

There were $315,000 of gross realized gains and no realized losses from the sale of available for sale securities during the three months ended September 30, 2016 and there were $4.4 million of realized gains and no realized losses from the sale of available for sale securities during the nine months ended September 30, 2016.

Allocations of the allowance for loan losses relative to impaired loans were $580,000 and $2.8 million at September 30, 2016 and December 31, 2015, respectively. Approximately $430,000 and $1.2 million of interest income was recognized on average impaired loans of $42.1 million and $34.0 million for the three and nine months ended September 30, 2016. Interest income recognized on impaired loans on a cash basis during the three and nine months ended September 30, 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.

The restructured loans were modified by deferring amortized principal payments, changing the maturity date, changing the interest rate and requiring interest only payments for a period of 12 months. Based on the fair value of the collateral, a specific reserve of $78,000 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 nine months ended September 30, 2016, the Company modified 67 loans with a recorded investment of $13.4 million prior to modification which was deemed troubled debt restructuring. The restructured loans were modified by deferring amortized principal payments, changing the maturity date, changing the interest rate and requiring interest only payments for a period of 12 months. Based on the fair value of the collateral, a specific reserve of $402,000 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 September 30, 2015, the Company modified eight loans with a recorded investment of $610,000 and during the nine months ended September 30, 2015, the Company modified fifteen loans with a total recorded investment of $1,338,000 prior to modification which were deemed troubled debt restructuring. The restructured loans were modified by changing various terms, including changing the maturity date, deferring amortized principal payments and requiring interest only payments for a period of 12 months. Based on the fair value of the collateral, a $113,000 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 was one consumer loan for which a payment default occurred during the nine months ended September 30, 2016, that had been modified as a TDR within 12 months or less of the payment default. A charge off of $39,000 was recorded for this loan. There were no loans during the nine months ended September 30, 2015 for which there was a payment default. 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 $167,000 at September 30, 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 September 30, 2016, the Company had $2,034,000 of consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceedings are in process. At September 30, 2016, the Company had $5,875,000 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 $20.4 million and $23.5 million that are accounted for under ASC Topic 310-30 and are classified as substandard (Risk Rating 6) as of September 30, 2016 and December 31, 2015, respectively. Of the remaining loans acquired and accounted for under ASC Topic 310-20, $52.8 million and $49.9 million were classified (Risk Ratings 6, 7 and 8 – see classified loans discussion below) at September 30, 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 prior to acquisition 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 $178.7 million and $153.7 million, as of September 30, 2016 and December 31, 2015, respectively. The following table presents a summary of loans by credit risk rating as of September 30, 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) external factors and pressure from competition, (6) the experience, ability and depth of lending management and staff, (7) seasoning of new products obtained and new markets entered through acquisition and (8) 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.

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 third quarter of 2016, the Company evaluated $340.1 million of net loans ($348.8 million gross loans less $8.7 million discount) purchased in conjunction with the acquisition of Citizens, described in Note 2, Acquisitions, in accordance with the provisions of ASC Topic 310-20, Nonrefundable Fees and Other Costs Loans and Debt Securities Acquired with Deteriorated Credit Quality During the 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. 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 $10.7 million of net loans ($15.7 million gross loans less $5.0 million discount) purchased in conjunction with the acquisition of Liberty for impairment in accordance with the provisions of ASC Topic 310-30. 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 following is a summary of the loans acquired in the Citizens acquisition on September 9, 2016, as of the date of acquisition. (in thousands) Not Impaired Impaired Contractually required principal and interest at acquisition $ 348,756 $ 1,605 Non-accretable difference (expected losses and foregone interest) -- (848 ) Cash flows expected to be collected at acquisition 348,756 757 Accretable yield (8,690 ) -- Basis in acquired loans at acquisition $ 340,066 $ 757 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 and nine months ended September 30, 2016 and 2015 is shown below: Three Months Ended Nine Months Ended (In thousands) 2016 2015 2016 2015 Impact on net interest income $ 65 $ 9,699 $ 1,240 $ 19,024 Non-interest income (1) -- (2,033 ) -- (7,718 ) Net impact to pre-tax income 65 7,666 1,240 11,306 Net impact, net of taxes $ 40 $ 4,658 $ 754 $ 6,871 ______________________________ (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 and nine months ended September 30, 2016 and 2015. Three Months Ended Nine Months Ended (In thousands) Accretable Carrying Accretable Carrying Beginning balance $ 2,365 $ 20,663 $ 954 $ 23,469 Additions -- 1,614 -- 1,614 Accretable yield adjustments 171 -- 3,245 -- Accretion (555 ) 555 (2,218 ) 2,218 Payments and other reductions, net -- (1,412 ) -- (5,881 ) Balance, ending $ 1,981 $ 21,420 $ 1,981 $ 21,420 Three Months Ended Nine Months Ended (In thousands) Accretable Carrying Accretable Carrying Beginning balance $ 15,048 $ 160,094 $ 20,635 $ 169,098 Additions -- -- (116 ) 17,750 Accretable yield adjustments 575 -- 6,018 -- Accretion (9,744 ) 9,744 (20,658 ) 20,658 Payments and other reductions, net (4,476 ) (129,985 ) (4,476 ) (167,653 ) Balance, ending $ 1,403 $ 39,853 $ 1,403 $ 39,853 Purchased impaired loans are evaluated on an individual borrower basis. Because some loans evaluated by the Company, previously covered by loss share agreements, were determined to have experienced impairment in the estimated credit quality or cash flows during 2014, the Company recorded a provision to establish a $954,000 allowance for loan losses for covered purchased impaired loans. During 2015, the Company recorded a provision totaling $736,000 to cover impairment in the estimated credit quality of acquired loans, not covered by loss share. Non-covered loans were subsequently charged-off and the allowance was used during 2015. Because of the termination of the loss share agreements, the allowance for previously covered loans was reclassified to allowance for acquired non-covered loans, resulting in a total allowance on acquired non-covered loans of $954,000 at September 30, 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 or nine months ended September 30, 2016. For the three and nine months ended September 30, 2015, amortization expense of $27,000 and $107,000, respectively and an adjustment related to changes in expected losses of $187,000 and $720,000, respectively 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 $348.8 million at September 30, 2016 and $327.7 million at December 31, 2015. The Company recorded $21.8 million during the three months ended September 30, 2016 as a result of its acquisition of Citizens. Goodwill impairment was neither indicated nor recorded during the nine months ended September 30, 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 premium of $4.9 million was recorded during the third quarter of 2016 as part of the Citizens acquisition. 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, 2015 included an insurance line of business and the Company recorded an intangible asset of $420,000 during the first quarter of 2015.

The debt has a 10 year amortization with a 5 year balloon payment due in October 2020. At September 30, 2016, the Company had $120.0 million of Federal Home Loan Bank (“FHLB”) advances with original maturities of one year or less. The Company had total FHLB advances of $166.2 million at September 30, 2016, with approximately $830.2 million of additional advances available from the FHLB. The FHLB advances are secured by mortgage loans and investment securities totaling approximately $1.105 billion at September 30, 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. The Company’s obligations under the junior subordinated securities and other relevant trust agreements, in aggregate, constitute a full and unconditional guarantee by the Company of each respective trust’s obligations under the trust securities issued by each respective trust.

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 September 30, 2016, the Company’s subsidiary bank had approximately $2.7 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 September 30, 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 13.81% at September 30, 2016.

Stock-based compensation expense is recognized ratably over the requisite service period for all stock-based awards. There was $1,161,000 of unrecognized stock-based compensation expense related to stock options at September 30, 2016. Unrecognized stock-based compensation expense related to non-vested stock awards was $7,380,000 at September 30, 2016. At such date, the weighted-average period over which this unrecognized expense is expected to be recognized was 2.8 years. The intrinsic value of stock options outstanding and stock options exercisable at September 30, 2016 was $3,534,000 and $2,247,000. Aggregate intrinsic value represents the difference between the Company’s closing stock price on the last trading day of the period, which was $49.90 as of September 30, 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 nine months ended September 30, 2016 and September 30, 2015, was $1,063,000 and $1,672,000, 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 nine months ended September 30, 2016 and 2015 was $11.64 and $7.81 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: Nine Months Ended Nine Months Ended Expected dividend yield 1.96 % 2.06 % Expected stock price volatility 27.34 % 16.96 % Risk-free interest rate 2.01 % 2.17 % Expected life of options (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 September 30, 2016, the Company had outstanding commitments to extend credit aggregating approximately $616,175,000 and $1,063,150,000 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 $30,053,000 and $23,515,000 at September 30, 2016, and December 31, 2015, respectively, with terms ranging from 9 months to 15 years. At September 30, 2016 and December 31, 2015, the Company had no deferred revenue under standby letter of credit agreements.

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 September 30, 2016 and December 31, 2015.

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 is performed on all loans over $1.5 million rated Substandard or worse, all existing impaired loans regardless of size and all TDRs. 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 September 30, 2016 and December 31, 2015.

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 September 30, 2016 Financial assets: Cash and cash equivalents $ 454,523 $ 454,523 $ -- $ -- $ 454,523 Interest bearing balances due from banks - time 4,393 -- 4,393 -- 4,393 Held-to-maturity securities 496,594 -- 508,910 -- 508,910 Mortgage loans held for sale 28,069 -- -- 28,069 28,069 Interest receivable 27,390 -- 27,390 -- 27,390 Legacy loans (net of allowance) 3,908,995 -- -- 3,916,460 3,916,460 Loans acquired (net of allowance) 1,458,198 -- -- 1,460,983 1,460,983 Financial liabilities: Non-interest bearing transaction accounts 1,473,420 -- 1,473,420 -- 1,473,420 Interest bearing transaction accounts and savings deposits 3,815,939 -- 3,815,939 -- 3,815,939 Time deposits 1,328,022 -- -- 1,325,370 1,325,370 Federal funds purchased and securities sold under agreements to repurchase 124,289 -- 124,289 -- 124,289 Other borrowings 215,276 -- 224,206 -- 224,206 Subordinated debentures 60,290 -- 54,817 -- 54,817 Interest payable 1,689 -- 1,689 -- 1,689 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 and nine months ended September 30, 2016 and 2015: Three Months Ended Nine Months Ended (In thousands, except per share data) 2016 2015 2016 2015 Net income available to common shareholders $ 23,429 $ 21,598 $ 69,819 $ 50,325 Average common shares outstanding 30,621 29,927 30,434 27,379 Average potential dilutive common shares 223 119 223 119 Average diluted common shares 30,844 30,046 30,657 27,498 Basic earnings per share $ 0.77 $ 0.72 $ 2.29 $ 1.84 Diluted earnings per share (1) (2) $ 0.76 $ 0.72 $ 2.28 $ 1.83 ______________________________ (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 2015 year-to-date EPS, diluted EPS for the second quarter of 2015 would require a computed amount of $0.74, producing a difference of $.02 from actual third quarter 2015 diluted EPS of $0.72. This difference is based on the direct result of the varying denominator for each period presented. (2) Stock options to purchase 61,395 and 326,565 shares for the three and nine months ended September 30, 2016 and 2015, respectively, were not included in the diluted EPS calculation because the exercise price of those options exceeded the average market price.

[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 2015 year-to-date EPS, diluted EPS for the second quarter of 2015 would require a computed amount of $0.74, producing a difference of $.02 from actual third quarter 2015 diluted EPS of $0.72. This difference is based on the direct result of the varying denominator for each period presented.
[2]	Stock options to purchase 61,395 and 326,565 shares for the three and nine months ended September 30, 2016 and 2015, respectively, were not included in the diluted EPS calculation because the exercise price of those options exceeded the average market price.
