LOANS AND LEASES [Abstract]
LOANS AND LEASES	NOTE 2 – LOANS AND LEASES  The Company’s loan and lease portfolio is disaggregated into the following segments: commercial and industrial; real estate; credit card; and all other. The real estate segment is further disaggregated into the following classes: consumer mortgages; home equity; agricultural; commercial and industrial-owner occupied; construction, acquisition and development; and commercial. A summary of gross loans and leases by segment and class as of the dates indicated follows:      September 30, December 31,  2017 2016 2016   (In thousands)   Commercial and industrial $ 1,508,794 $ 1,619,668 $ 1,615,608  Real estate  Consumer mortgages 2,826,333 2,611,387 2,643,966  Home equity 626,961 622,566 628,846  Agricultural 247,211 242,171 245,377  Commercial and industrial-owner occupied 1,835,430 1,668,477 1,764,265  Construction, acquisition and development 1,175,979 1,121,386 1,157,248  Commercial real estate 2,336,219 2,240,717 2,237,719  Credit cards 104,613 107,447 109,656  All other 411,766 451,347 432,827  Gross Loans Total (1) 11,073,306 10,685,166 10,835,512  Less: Unearned Income 17,797 26,405 23,521  Net Loans $ 11,055,509 $ 10,658,761 $ 10,811,991   (1) Gross loans and leases are net of deferred costs of $3.5 million, $2.2 million and approximately $282,000 at September 30, 2017 and 2016 and December 31, 2016, respectively.

A substantial portion of construction, acquisition and development loans are secured by real estate in markets in which the Company is located. The Company’s loan policy generally prohibits loans for the sole purpose of carrying interest reserves. Certain of the construction, acquisition and development loans were structured with interest-only terms. A portion of the consumer mortgage and commercial real estate portfolios were originated through the permanent financing of construction, acquisition and development loans. Future economic distress could negatively impact borrowers’ and guarantors’ ability to repay their debt which would make more of the Company’s loans collateral dependent.

These credit quality indicators include, but are not limited to, recent credit performance, delinquency, liquidity, cash flows, debt coverage ratios, collateral type and loan-to-value ratio. The Company’s internal loan classification system is compatible with classifications used by the Federal Deposit Insurance Corporation, as well as other regulatory agencies. Loans may be classified as follows:  Pass: Loans which are performing as agreed with few or no signs of weakness. These loans show sufficient cash flow, capital and collateral to repay the loan as agreed.  Special Mention: Loans where potential weaknesses have developed which could cause a more serious problem if not corrected.  Substandard: Loans where well-defined weaknesses exist that require corrective action to prevent further deterioration. These loans are further characterized by the possibility that the Company will sustain some loss if the deficiencies are not corrected.  Doubtful: Loans having all the characteristics of Substandard and which have deteriorated to a point where collection and liquidation in full is highly questionable.

The Company’s recorded investment in loans considered impaired exclusive of accruing TDRs at September 30, 2017 and December 31, 2016 was $19.7 million and $38.2 million, respectively. At September 30, 2017 and December 31, 2016, $1.2 million and $12.9 million, respectively, of those impaired loans had a valuation allowance of approximately $ 581,000 and $ 4.4 million, respectively. The remaining balance of impaired loans of $18.5 million and $25.3 million at September 30, 2017 and December 31, 2016, respectively, have sufficient collateral supporting the collection of all outstanding principle or were charged down to fair value of the collateral, less estimated selling costs. Therefore, such loans did not have an associated valuation allowance. Impaired loans that were characterized as non-accruing TDRs totaled $1.0 million and $12.6 million at September 30, 2017 and December 31, 2016, respectively. Non-performing loans and leases (“NPLs”) consist of non-accrual loans and leases, loans and leases 90 days or more past due and still accruing, and loans and leases that have been restructured because of the borrower’s weakened financial condition. The following table presents information concerning NPLs as of the dates indicated:     September 30, December 31,  2017 2016 2016  (In thousands)   Non-accrual loans and leases $ 55,796 $ 70,725 $ 71,812  Loans and leases 90 days or more past due, still accruing 1,855 2,255 3,983  Restructured loans and leases still accruing 7,366 17,936 26,047  Total non-performing loans and leases $ 65,017 $ 90,916 $ 101,842  The Bank’s policy for all loan classifications provides that loans and leases are generally placed in non-accrual status if, in management’s opinion, payment in full of principal or interest is not expected or payment of principal or interest is more than 90 days past due, unless such loan or lease is both well-secured and in the process of collection. At September 30, 2017, the Company’s geographic NPL distribution was concentrated primarily in its Arkansas and Mississippi markets. The following table presents the Company’s nonaccrual loans and leases by segment and class as of the dates indicated:      September 30, December 31,  2017 2016 2016  (In thousands)  Commercial and industrial $ 8,776 $ 11,659 $ 13,679  Real estate  Consumer mortgages 23,635 20,196 21,084  Home equity 2,555 3,721 3,817  Agricultural 5,919 1,194 1,546  Commercial and industrial-owner occupied 7,558 11,983 10,791  Construction, acquisition and development 1,771 6,939 7,022  Commercial real estate 4,645 14,793 13,402  Credit cards 126 121 161  All other 811 119 310  Total $ 55,796 $ 70,725 $ 71,812  In the normal course of business, management will sometimes grant concessions, which would not otherwise be considered, to borrowers that are experiencing financial difficulty. Loans identified as meeting the criteria set out in FASB ASC 310 are identified as TDRs. The concessions granted most frequently for TDRs involve reductions or delays in required payments of principal and interest for a specified period or the rescheduling of payments in accordance with a bankruptcy plan. In most cases, the conditions of the credit also warrant nonaccrual status, even after the restructure occurs. Other conditions that warrant a loan being considered a TDR include reductions in interest rates to below market rates due to bankruptcy plans or by the bank in an attempt to assist the borrower in working through liquidity problems. As part of the credit approval process, the restructured loans are evaluated for adequate collateral protection in determining the appropriate accrual status at the time of restructure. TDRs recorded as nonaccrual loans may generally be returned to accrual status in years after the restructure if there has been at least a six-month period of sustained repayment performance by the borrower in accordance with the terms of the restructured loan. During the third quarter of 2017, the most common concessions that were granted involved rescheduling payments of principal and interest over a longer amortization period, granting a period of reduced principal payment or interest only payment for a limited time period, or the rescheduling of payments in accordance with a bankruptcy plan.

Also it was more likely than not that the Company would not be required to sell the securities prior to recovery of costs. Therefore, the impairments related to these securities were determined to be temporary. No other-than-temporary impairment was recorded during the first nine months of 2017 or 2016.

PER SHARE DATA [Abstract]
PER SHARE DATA	NOTE 6 – PER SHARE DATA  Basic earnings per share (“EPS”) are calculated using the two-class method. The two-class method provides that unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and shall be included in the computation of basic EPS. Diluted EPS is computed using the weighted-average number of shares determined for the basic EPS computation plus the shares resulting from the assumed exercise of all outstanding share-based awards using the treasury stock method. There were no weighted-average antidilutive stock options to purchase Company common stock for the three months and nine months ended September 30, 2017 to be excluded from diluted shares. There were no antidilutive other equity awards for the three months and nine months ended September 30, 2017 . Weighted-average antidilutive stock options to purchase approximately 32,400 and 45,000 shares of Company common stock with a weighted average exercise price of $24.47 and $24.71 per share for the three months and nine months ended September 30, 2016, respectively, were excluded from diluted shares. There were no antidilutive other equity awards for the three months and nine months ended September 30, 2016 . The following table provides a reconciliation of the numerators and denominators of the basic and diluted earnings per share computations for the periods shown:       Three months ended September 30,  2017 2016  Income Shares Per Share Income Shares Per Share  (Numerator) (Denominator) Amount (Numerator) (Denominator) Amount Basic EPS (In thousands, except per share amounts)  Income available to common  shareholders $ 39,528 90,912 $ 0.43 $ 37,817 94,304 $ 0.40  Effect of dilutive share-  based awards 188 260   Diluted EPS  Income available to common  shareholders plus assumed  exercise of all outstanding  share-based awards $ 39,528 91,100 $ 0.43 $ 37,817 94,564 $ 0.40       Nine months ended September 30,  2017 2016  Income Shares Per Share Income Shares Per Share  (Numerator) (Denominator) Amount (Numerator) (Denominator) Amount   Basic EPS (In thousands, except per share amounts)  Income available to common  shareholders $ 115,510 91,974 $ 1.26 $ 95,058 94,378 $ 1.01  Effect of dilutive share-  based awards 183 239   Diluted EPS  Income available to common  shareholders plus assumed  exercise of all outstanding  share-based awards $ 115,510 92,157 $ 1.25 $ 95,058 94,617 $ 1.00

GOODWILL AND OTHER INTANGIBLE ASSETS [Abstract]
GOODWILL AND OTHER INTANGIBLE ASSETS	NOTE 8 – GOODWILL AND OTHER INTANGIBLE ASSETS  The carrying amounts of goodwill by operating segment for the nine months ended September 30, 2017 were as follows:     Community Insurance  Banking Agencies Total  (In thousands)  Balance as of December 31, 2016 $ 217,618 $ 83,180 $ 300,798  Goodwill recorded during the period - - -  Balance as of September 30, 2017 $ 217,618 $ 83,180 $ 300,798  The Company’s policy is to assess goodwill for impairment at the reporting segment level on an annual basis or sooner if an event occurs or circumstances change which indicate that the fair value of a reporting segment is below its carrying amount. Impairment is the condition that exists when the carrying amount of goodwill exceeds its implied fair value . Accounting standards require management to estimate the fair value of each reporting segment in assessing impairment at least annually. The Company’s annual assessment date is during the Company’s fourth quarter. No events occurred during the first nine months of 2017 that indicated the necessity of an earlier goodwill impairment assessment. In the current economic environment, forecasting cash flows, credit losses and growth in addition to valuing the Company’s assets with any degree of assurance is very difficult and subject to significant changes over very short periods of time. Management will continue to update its analysis as circumstances change. As market conditions continue to be volatile and unpredictable, impairment of goodwill related to the Company’s reporting segments may be necessary in future periods. The following tables present information regarding the components of the Company’s identifiable intangible assets for the dates and periods indicated:        As of As of  September 30, 2017 December 31, 2016  Gross Carrying Accumulated Gross Carrying Accumulated  Amount Amortization Amount Amortization  Amortized intangible assets: (In thousands)  Core deposit intangibles $ 27,801 $ 24,035 $ 27,801 $ 23,721  Customer relationship intangibles 45,758 $ 31,980 46,568 30,406  Non-solicitation intangibles 1,650 $ 1,022 1,850 886  Total $ 75,209 $ 57,037 $ 76,219 $ 55,013   Unamortized intangible assets:  Trade names $ 688 $ - $ 688 $ -      Three months ended Nine months ended  September 30, September 30,  2017 2016 2017 2016   Aggregate amortization expense for: (In thousands)  Core deposit intangibles $ 103 $ 112 $ 314 $ 340  Customer relationship intangibles 779 737 2,384 2,075  Non-solicitation intangibles 112 74 336 257  Total $ 994 $ 923 $ 3,034 $ 2,672  The following table presents information regarding estimated amortization expense on the Company’s amortizable identifiable intangible assets for the year ending December 31, 2017 and the succeeding four years:      Customer Non-  Core Deposit Relationship Solicitation  Intangibles Intangibles Intangibles Total   Estimated Amortization Expense: (In thousands)  For the year ending December 31, 2017 $ 419 $ 3,147 $ 448 $ 4,014  For the year ending December 31, 2018 390 2,696 419 3,505  For the year ending December 31, 2019 363 2,330 97 2,790  For the year ending December 31, 2020 340 2,014 - 2,354  For the year ending December 31, 2021 251 1,591 - 1,842

RECENT PRONOUNCEMENTS [Abstract]
RECENT PRONOUNCEMENTS	NOTE 10 – RECENT PRONOUNCEMENTS  In September 2014, the FASB issued an ASU regarding accounting for revenue from contracts with customers. This ASU implements a common revenue standard that clarifies the principles for recognizing revenue. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: (i)identify the contract(s)with a customer, (ii)identify the performance obligations in the contract, (iii)determine the transaction price, (iv)allocate the transaction price to the performance obligations in the contract and (v) recognize revenue when (or as)the entity satisfies a performance obligation. ASU 2014-09 was originally going to be effective on January 1, 2017; however, the FASB issued ASU 2015-14, “Revenue from Contracts with Customers (Topic 606)–Deferral of the Effective Date" which deferred the effective date of ASU 2014-09 by one year to January 1, 2018. The Company has conducted its initial assessment and is currently evaluating contracts to assess and quantify accounting methodology changes resulting from the adoption of ASU 2014-09. The Company’s revenues are comprised of net interest income of financial assets and financial liabilities, which are explicitly excluded from the scope of the new standard and noninterest revenue. As the majority of the Company’ revenues are derived from net interest revenue, the ASU is no t expected to have a material impact on the financial position and results of operations of the Company. The Company expects to change how we recognize certain components of noninterest revenue; however we do not expect these changes to have a significant impact on our financial statements. We will adopt the standard in the first quarter of 2018 with a cumulative effect adjustment to opening retained earnings, if such adjustment is deemed to be significant. In February 2016, the FASB issued an ASU regarding accounting for leases. ASU 2016-02 requires all leases, except short-term leases, to be recognized on the lessee’s balance sheet at commencement date as a lease liability for the obligation of lease payments and a right-of-use asset for the right to use/control a specified asset for the lease term. This ASU is effective for interim and annual periods beginning after December 15, 2018. This ASU is not expected to have a material impact on the financial position and results of operations of the Company. In March 2016, the FASB issued an ASU regarding stock compensation and improvements to employee share-based payment accounting. This ASU changes five aspects of the accounting for share-based payment award transactions including 1) accounting for income taxes; 2) classification of excess tax benefits on the statement of cash flows; 3) forfeitures; 4) minimum statutory tax withholding requirements; 5) classification of employee taxes paid on the statement of cash flows when an employer withholds shares for tax-withholding purposes. Effective January 1, 2017, the Company adopted provisions of this ASU which makes several revisions to equity compensation accounting. Under the new guidance all excess tax benefits and deficiencies that occur when an award vests, is exercised, or expires are recognized in income tax expense as discrete period items. Previously, these transactions were typically recorded directly within equity. Consistent with this change, excess tax benefits and deficiencies are no longer included within estimated proceeds when performing the calculation for diluted earnings per share. The presentation of excess tax benefits in the statement of cash flows shifted to an operating activity from the prior classification as a financing activity. ASU 2016-09 also provides an accounting policy election to recognize forfeitures of awards as they occur when estimating stock-based compensation expense rather than the previous requirement to estimate forfeitures from inception. Transition to the new guidance was accomplished through a combination of retrospective, cumulative-effect adjustment to equity and prospective methodologies. The Company estimates based on currently enacted tax rates, that adoption of ASU 2016-09 in 2017 will result in an incremental effect on tax provision ranging from approximately $ 561 ,000 to approximately $ 930, 000 of tax benefit. The actual effects of adoption in 2017 will primarily depend upon the share price of the Company’ stock, which affects the vesting of certain performance awards, probability of exercise of certain stock options and the magnitude of windfalls for all awards upon either vesting or exercise. The effects on earnings per share calculations and election to account for forfeitures as incurred have not been significant. In June 2016, the FASB issued an ASU regarding credit losses on financial instruments. This ASU will provide financial statement users with more information regarding the expected credit losses on financial instruments and other commitments to extend credit at each reporting date rather than the incurred loss impairment method. This ASU is effective for interim and annual periods after December 15, 2019. The Company is currently evaluating the potential impact of ASU 2016-13 on our financial statements . A cross-functional working group was designated comprised of individuals from functional areas including credit and finance. The Company is currently coordinating an implementation plan to include assessment of processes, portfolio segmentation, model development, system requirements and the identification of data and resource needs, among other things. While currently unable to reasonably estimate the impact of adopting this ASU, it is expected that the impact of adoption may be influenced by the composition, characteristics and quality of our loan and securities portfolios as well as the prevailing economic conditions and forecasts as of the adoption date. In August 2016, the FASB issued an ASU regarding how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The update addresses eight specific cash flow items whose objective is to reduce existing diversity in practice. This ASU is effective for interim and annual periods after December 15, 2017. The adoption of this ASU is not expected to have a material impact on the financial position and results of operations of the Company. In January 2017, the FASB issued an ASU regarding how goodwill is tested annually. This ASU will simplify the measurement of goodwill which will reduce cost and complexity of the evaluating process. This ASU is effective beginning after December 15, 2019. The adoption of this ASU will not have a material impact on the financial position and results o f operations of the Company. In March 2017, the FASB issued an ASU in order to shorten the amortization period for certain callable debt securities held at a premium. This ASU is effective for interim and annual periods after December 15, 2018. As the Company already uses the earliest call date for debt securities, the adoption of this ASU is not expected to have a material impact on the financial position and results of operations of the Company. In March 2017, the FASB issued an ASU to improve the presentation of net periodic pension cost and net periodic postretirement benefit cost in the financial statements. This ASU will be effective for interim and annual periods after December 15, 2017. As the Company already includes service cost from pension benefits in employee benefits expense, the adoption of this ASU will not have a material impact on the financial position and results of operations of the Company.

SEGMENT REPORTING [Abstract]
SEGMENT REPORTING	NOTE 11 - SEGMENT REPORTING  The Company determines reportable segments based upon the services offered, the significance of those services to the Company's financial condition and operating results and management's regular review of the operating results of those services. The Company's primary segment is the Banking Services Group, which includes providing a full range of deposit products, commercial loans and consumer loans. The Company has also designated four additional reportable segments --Mortgage, Insurance Agencies, Wealth Management, and General Corporate and Other. The Company’s Mortgage segment includes the mortgage banking activities of originating mortgage loans, selling mortgage loans in the secondary market and servicing the mortgage loans that are sold on a servicing retained basis. The Company's insurance agencies serve as agents in the sale of commercial lines of insurance and full lines of property and casualty, life, health and employee benefits products and services. The Wealth Management segment offers individuals, businesses, governmental institutions and non-profit entities a wide range of solutions to help protect, grow and transfer wealth. Offerings include credit related products, trust and investment management, asset management, retirement and savings solutions, estate planning and annuity products. The General Corporate and Other segment includes other activities not allocated to Banking Services Group, Mortgage, Insurance Agencies or Wealth Management segments. Results of operations and selected financial information by segment for the three-month and nine-month periods ended September 30, 2017 and 2016 were as follows:     Banking Services Group Mortgage Insurance Agencies Wealth Management General Corporate and Other Total  (In thousands)  Three months ended September 30, 2017  Results of Operations  Net interest revenue $ 115,899 $ 4,620 $ 11 $ 12 $ 19 $ 120,561  Provision for credit losses - - - - 500 500  Net interest revenue after provision for credit losses 115,899 4,620 11 12 (481) 120,061  Noninterest revenue 21,428 6,910 28,789 5,862 2,971 65,960  Noninterest expense 74,643 7,050 25,766 3,991 15,453 126,903  Income before income taxes 62,684 4,480 3,034 1,883 (12,963) 59,118  Income tax expense (benefit) 21,967 1,677 1,228 705 (5,987) 19,590  Net income $ 40,717 $ 2,803 $ 1,806 $ 1,178 $ (6,976) $ 39,528  Selected Financial Information  Total assets at end of period $ 11,421,704 $ 630,986 $ 225,458 $ 24,047 $ 2,458,199 $ 14,760,394  Depreciation and amortization 5,500 226 1,152 25 664 7,567        Banking Services Group Mortgage Insurance Agencies Wealth Management General Corporate and Other Total  (In thousands)  Three months ended September 30, 2016  Results of Operations  Net interest revenue $ 111,772 $ 3,183 $ 11 $ 3 $ (379) $ 114,590  Provision for credit losses - - - - - -  Net interest revenue after provision for credit losses 111,772 3,183 11 3 (379) 114,590  Noninterest revenue 23,248 11,080 27,913 5,728 1,704 69,673  Noninterest expense 78,931 6,294 25,335 4,257 13,500 128,317  Income before income taxes 56,089 7,969 2,589 1,474 (12,175) 55,946  Income tax expense (benefit) 18,711 2,906 1,051 538 (5,077) 18,129  Net income $ 37,378 $ 5,063 $ 1,538 $ 936 $ (7,098) $ 37,817  Selected Financial Information  Total assets at end of period $ 11,358,022 $ 518,880 $ 217,062 $ 19,509 $ 2,498,010 $ 14,611,483  Depreciation and amortization 5,485 147 1,075 28 606 7,341     Banking Services Group Mortgage Insurance Agencies Wealth Management General Corporate and Other Total  (In thousands)  Nine months ended September 30, 2017  Results of Operations  Net interest revenue $ 340,068 $ 12,472 $ 32 $ 25 $ 53 $ 352,650  Provision for credit losses - - - - 2,500 2,500  Net interest revenue after provision for credit losses 340,068 12,472 32 25 (2,447) 350,150  Noninterest revenue 64,986 22,036 93,188 17,237 7,512 204,959  Noninterest expense 225,119 20,829 78,416 12,120 45,081 381,565  Income before income taxes 179,935 13,679 14,804 5,142 (40,016) 173,544  Income tax expense (benefit) 62,351 5,084 6,063 1,911 (17,375) 58,034  Net income $ 117,584 $ 8,595 $ 8,741 $ 3,231 $ (22,641) $ 115,510  Selected Financial Information  Total assets at end of period $ 11,421,704 $ 630,986 $ 225,458 $ 24,047 $ 2,458,199 $ 14,760,394  Depreciation and amortization 16,553 531 3,520 76 1,935 22,615     Banking Services Group Mortgage Insurance Agencies Wealth Management General Corporate and Other Total  (In thousands)  Nine months ended September 30, 2016  Results of Operations  Net interest revenue $ 330,523 $ 8,614 $ 46 $ 5 $ (1,123) $ 338,065  Provision for credit losses - - - - 3,000 3,000  Net interest revenue after provision for credit losses 330,523 8,614 46 5 (4,123) 335,065  Noninterest revenue 69,263 20,778 89,821 17,029 6,035 202,926  Noninterest expense 231,836 18,740 75,598 12,753 58,463 397,390  Income before income taxes 167,950 10,652 14,269 4,281 (56,551) 140,601  Income tax expense (benefit) 57,072 3,873 5,702 1,556 (22,660) 45,543  Net income $ 110,878 $ 6,779 $ 8,567 $ 2,725 $ (33,891) $ 95,058  Selected Financial Information  Total assets at end of period $ 11,358,022 $ 518,880 $ 217,062 $ 19,509 $ 2,498,010 $ 14,611,483  Depreciation and amortization 16,128 438 3,169 85 1,875 21,695  The change in income for the Banking Services Group for the three months and nine months ended September 30, 2017 compared to the same periods in 2016 is mainly due to an increase in interest revenue for loans and leases due to the balance and interest rate increase of net loans and leases. The change in income for the Mortgage segment for the three months and nine months ended September 30, 2017 compared to the same periods in 2016 is primarily a result of the negative MSR adjustment of approximately $ 46,000 and approximately $ 621 ,000 recorded during the third quarter and first nine months of 2017, respectively, compared to a positive MSR adjustment of $ 1.8 million and a negative adjustment of $10.2 million recorded during the third quarter and first nine months of 2016 , respectively . The decrease in the loss in the General, Corporate and Other segment when comparing nine-month period is a result of the pre-tax charge of $10.3 million related to a liability associated with an ongoing regulatory matter recorded during the first nine months of 2016 with no such charge recorded during the first nine months of 2017.

MORTGAGE SERVICING RIGHTS [Abstract]
MORTGAGE SERVICING RIGHTS	NOTE 12 – MORTGAGE SERVICING RIGHTS  Mortgage servicing rights (“MSRs”), which are recognized as a separate asset on the date the corresponding mortgage loan is sold on a servicing retained basis, are recorded at fair value as determined at each accounting period end. An estimate of the fair value of the Company’s MSRs is determined utilizing assumptions about factors such as mortgage interest rates, discount rates, mortgage loan prepayment speeds, market trends and industry demand. Data and assumptions used in the fair value calculation related to MSRs as of the dates indicated were as follows:     September 30, December 31,  2017 2016 2016  (Dollars in thousands)  Unpaid principal balance $6,506,550 $6,285,027 $6,384,649  Weighted-average prepayment speed (CPR) 9.4 12.7 9.4  Discount rate (annual percentage) 9.8 9.8 9.8  Weighted-average coupon interest rate (percentage) 4.0 4.0 3.9  Weighted-average remaining maturity (months) 326.0 322.0 323.0  Weighted-average servicing fee (basis points) 26.7 26.7 26.7  Because the valuation is determined by using discounted cash flow models, the primary risk inherent in valuing the MSRs is the impact of fluctuating interest rates on the estimated life of the servicing revenue stream. The use of different estimates or assumptions could also produce different fair values. As of September 30, 2017, the Company had a hedge in place designed to cover approximately 6% of the MSR. The Company is susceptible to fluctuations in their value of its MSRs in changing interest rate environments. The Company has only one class of mortgage servicing asset comprised of closed end loans for one-to-four family residences, secured by first liens. The following table presents the activity in this class for the periods indicated:     2017 2016  (In thousands)  Fair value as of January 1 $ 65,263 $ 57,268  Additions:  Origination of servicing assets 9,031 10,684  Changes in fair value:  Due to payoffs/paydowns (7,203) (5,784)  Due to change in valuation inputs or assumptions  used in the valuation model (671) (10,233)  Other changes in fair value (3) (5)  Fair value as of September 30 $ 66,417 $ 51,930  All of the changes to the fair value of the MSRs are recorded as part of mortgage banking noninterest revenue on the income statement. As part of mortgage banking noninterest revenue, the Company recorded contractual servicing fees of $4.4 million and $4.3 million and late and other ancillary fees of approximately $206,000 and $243,000 for the three months ended September 30, 2017 and 2016, respectively. The Company recorded contractual servicing fees of $13.1 million and $12.6 million and late and other ancillary fees of $1.0 million and $1.5 million for the nine months ended September 30, 2017 and 2016, respectively.

DERIVATIVE INSTRUMENTS AND OFFSETTING ASSETS AND LIABILITIES [Abstract]
DERIVATIVE INSTRUMENTS AND OFFSETTING ASSETS AND LIABILITIES	NOTE 13 – DERIVATIVE INSTRUMENTS AND OFFSETTING ASSETS AND LIABILITIES  The derivatives held by the Company include commitments to fund fixed-rate mortgage loans to customers and forward commitments to sell individual fixed-rate mortgage loans. The Company’s objective in obtaining the forward commitments is to mitigate the interest rate risk associated with the commitments to fund the fixed-rate mortgage loans. Both the commitments to fund fixed-rate mortgage loans and the forward commitments to sell individual fixed-rate mortgage loans are reported at fair value, with adjustments being recorded in current period earnings, and are not accounted for as hedges. At September 30, 2017, the notional amount of forward commitments to sell individual fixed-rate mortgage loans was $ 197.6 million with a carrying value and fair value reflecting a gain of approximately $286,000 . At September 30, 2016, the notional amount of forward commitments to sell individual fixed-rate mortgage loans was $264.3 million with a carrying value and fair value reflecting a loss of $ 1.1 million. At September 30, 2017, the notional amount of commitments to fund individual fixed-rate mortgage loans was $ 135.8 million with a carrying value and fair value reflecting a gain of $3.5 million. At September 30, 2016, the notional amount of commitments to fund individual fixed-rate mortgage loans was $223.0 million with a carrying value and fair value reflecting a gain of $6.9 million. The Company also enters into derivative financial instruments in the form of interest rate swaps to meet the financing, interest rate and equity risk management needs of its customers. Upon entering into these interest rate swaps to meet customer needs, the Company enters into offsetting positions to minimize interest rate and equity risk to the Company. These derivative financial instruments are reported at fair value with any resulting gain or loss recorded in current period earnings. These instruments and their offsetting positions are recorded in other assets and other liabilities on the consolidated balance sheets. As of September 30, 2017, the notional amount of customer related derivative financial instruments was $325.6 million with an average maturity of 25 months, an average interest receive rate of 3.6% and an average interest pay rate of 5.6% . As of September 30, 2016, the notional amount of customer related derivative financial instruments was $336.0 million with an average maturity of 33 months, an average interest receive rate of 2.8% and an average interest pay rate of 5.6% . Additionally, the Bank utilizes securities sold under agreements to repurchase to facilitate the needs of our customers and to facilitate secured short-term funding needs. Securities sold under agreements to repurchase are stated at the amount of cash received in connection with the transaction. The Bank monitors collateral levels on a continuous basis and may be required to provide additional collateral based on the fair value of the underlying securities . Securities sold under agreement to repurchase were $ 421 .0 million and $469.0 million at September 30, 2017 and 2016, respectively. Certain financial instruments, such as derivatives, may be eligible for offset in the consolidated balance sheet and/or subject to master netting arrangements or similar agreements. The Bank’s derivative transactions with upstream financial institution counterparties are generally executed under International Swaps and Derivative Association master agreements which include “right of set-off” provisions. In such cases, there is generally a legally enforceable right to offset recognized amounts and there may be an intention to settle such amounts on a net basis. Nonetheless, the Bank does not generally offset such financial instruments for financial reporting purposes. The following tables present components of financial instruments eligible for offsetting for the periods indicated:     September 30, 2017  Gross Amounts Not Offset  in the Consolidated  Balance Sheet  Financial  Gross Amount Gross Amount Net Amount Financial Collateral Net  Recognized Offset Recognized Instruments Pledged Amount  (In thousands)  Financial assets:  Derivatives:  Forward commitments $ 3,938 $ - $ 3,938 $ - $ - $ 3,938  Loan/lease interest rate swaps 4,374 - 4,374 - - 4,374  Total financial assets $ 8,312 $ - $ 8,312 $ - $ - $ 8,312  .

FAIR VALUE DISCLOSURES

FAIR VALUE DISCLOSURES	9 Months Ended

FAIR VALUE DISCLOSURES [Abstract]
FAIR VALUE DISCLOSURES	NOTE 14 – FAIR VALUE DISCLOSURES  “Fair value” is defined by FASB ASC 820, Fair Value Measurement (“FASB ASC 820”), 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. FASB ASC 820 establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs are inputs that reflect the reporting entity’s assumptions about the assumptions that market participants would use in pricing the asset or liability developed based on the best information available under the circumstances. The hierarchy is broken down into the following three levels, based on the reliability of inputs:  Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities that are accessible at the measurement date.  Level 2: Significant other observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data.  Level 3: Significant unobservable inputs for the asset or liability that reflect the reporting entity’s own assumptions about the assumptions that market participants would use in pricing the asset or liability.  Determination of Fair Value  The Company uses the valuation methodologies listed below to measure different financial instruments at fair value. An indication of the level in the fair value hierarchy in which each instrument is generally classified is included. Where appropriate, the description includes details of the valuation models, the key inputs to those models as well as any significant assumptions.  Available-for-sale securities. Available-for-sale securities are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted prices, if available. If quoted prices are not available, fair values are determined by matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities. The Company’s available-for-sale securities that are traded on an active exchange, such as the New York Stock Exchange, are classified as Level 1. Available-for-sale securities valued using matrix pricing are classified as Level 2. Available-for-sale securities valued using matrix pricing that has been adjusted to compensate for the present value of expected cash flows, market liquidity, credit quality and volatility are classified as Level 3.  Mortgage servicing rights. The Company records MSRs at fair value on a recurring basis with subsequent remeasurement of MSRs based on change in fair value. An estimate of the fair value of the Company’s MSRs is determined by utilizing assumptions about factors such as mortgage interest rates, discount rates, mortgage loan prepayment speeds, market trends and industry demand. All of the Company’s MSRs are classified as Level 3. For additional information about the Company’s valuation of MSRs, see Note 12, Mortgage Servicing Rights.  Derivative instruments. The Company’s derivative instruments consist of commitments to fund fixed-rate mortgage loans to customers and forward commitments to sell individual fixed-rate mortgage loans. Fair value of these derivative instruments is measured on a recurring basis using recent observable market prices. The Company also enters into interest rate swaps to meet the financing, interest rate and equity risk management needs of its customers. The fair value of these instruments is either an observable market price or a discounted cash flow valuation using the terms of swap agreements but substituting original interest rates with prevailing interest rates ranging from 2.59% to 4.74% . The Company also considers the associated counterparty credit risk when determining the fair value of these instruments. The Company’s interest rate swaps, commitments to fund fixed-rate mortgage loans to customers and forward commitments to sell individual fixed-rate mortgage loans are classified as Level 3.  Loans held for sale. Loans held for sale are carried at fair value. The fair value of loans held for sale is based on commitments outstanding from investors as well as what secondary markets are currently offering for portfolios with similar characteristics. Therefore, loans held for sale are subjected to recurring fair value adjustments and are classified as Level 2. The Company obtains quotes, bids or pricing indications on all or part of these loans directly from the buyers. Premiums and discounts received or to be received on the quotes, bids or pricing indications are indicative of the fact that the cost is lower or higher than fair value.  Impaired loans. Loans considered impaired under FASB ASC 310 are loans for which, based on current information and events, it is probable that the creditor will be unable to collect all amounts due according to the contractual terms of the loan agreement. Impaired loans are subject to nonrecurring fair value adjustments to reflect (1) partial write-downs that are based on the observable market price or current appraised value of the collateral, or (2) the full charge-off of the loan carrying value. All of the Company’s impaired loans are classified as Level 3.  Other real estate owned. OREO is carried at the lower of cost or estimated fair value, less estimated selling costs and is subject to nonrecurring fair value adjustments. Estimated fair value is determined on the basis of independent appraisals and other relevant factors less an average of 7% for estimated selling costs. All of the Company’s OREO is classified as Level 3.  Off-Balance sheet financial instruments. The fair value of commitments to extend credit and standby letters of credit is estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreement and the present creditworthiness of the counterparties. The Company has reviewed the unfunded portion of commitments to extend credit as well as standby and other letters of credit, and has determined that the fair value of such financial instruments is not material. The Company classifies the estimated fair value of credit-related financial instruments as Level 3.

Fair value estimates, methods and assumptions that are used by the Company in estimating fair values of financial instruments and that are not disclosed above in Note 14 are set forth below.  Cash and Due From Banks. The carrying amounts for cash and due from banks approximate fair values due to their immediate and shorter-term maturities.  Loans and Leases. Fair values are estimated for portfolios of loans and leases with similar financial characteristics. The fair value of loans and leases is calculated by discounting scheduled cash flows through the estimated maturity using rates the Company would currently offer customers based on the credit and interest rate risk inherent in the loan or lease. Assumptions regarding credit risk, cash flows and discount rates are judgmentally determined using available market and borrower information. Estimated maturity represents the expected average cash flow period, which in some instances is different than the stated maturity. This entrance price approach results in a calculated fair value that would be different than an exit or estimated actual sales price approach and such differences could be significant. All of the Company’s loans and leases are classified as Level 3.  Deposit Liabilities . Under FASB ASC 825, the fair value of deposits with no stated maturity, such as noninterest bearing demand deposits, interest bearing demand deposits and savings, is equal to the amount payable on demand as of the reporting date. The fair value of certificates of deposit is based on the discounted value of contractual cash flows. The discount rate is estimated using the prevailing rates offered for deposits of similar maturities. The Company’s noninterest bearing demand deposits, interest bearing demand deposits and savings are classified as Level 1. Certificates of deposit are classified as Level 2.  Debt . The carrying amounts for federal funds purchased and repurchase agreements approximate fair value because of their short-term maturity. The fair value of the Company’s fixed-term Federal Home Loan Bank (“FHLB”) advances is based on the discounted value of contractual cash flows. The discount rate is estimated using the prevailing rates available for advances of similar maturities. The fair value of the Company’s junior subordinated debt is based on market prices or dealer quotes. The Company’s federal funds purchased, repurchase agreements and junior subordinated debt are classified as Level 1. FHLB advances are classified as Level 2.  Lending Commitments. The Company’s lending commitments are negotiated at prevailing market rates and are relatively short-term in nature. As a matter of policy, the Company generally makes commitments for fixed-rate loans for relatively short periods of time. Therefore, the estimated value of the Company’s lending commitments approximates the carrying amount and is immaterial to the financial statements. The Company’s lending commitments are classified as Level 2. The Company’s off-balance sheet commitments including letters of credit, which totaled $79.9 million at September 30, 2017, are funded at current market rates at the date they are drawn upon. It is management’s opinion that the fair value of these commitments would approximate their carrying value, if drawn upon. The following table presents carrying and fair value information of financial instruments at September 30, 2017 and December 31, 2016:      September 30, 2017 December 31, 2016  Carrying Fair Carrying Fair  Value Value Value Value  Assets: (In thousands)  Cash and due from banks $ 167,871 $ 167,871 $ 184,152 $ 184,152  Interest bearing deposits with other banks 52,316 52,316 38,813 38,813  Available-for-sale securities 2,359,967 2,359,967 2,531,676 2,531,676  Net loans and leases 10,936,013 10,967,885 10,688,255 10,692,820  Loans held for sale 138,353 138,353 166,927 166,927   Liabilities:  Noninterest bearing deposits 3,414,397 3,414,397 3,250,537 3,250,537  Savings and interest bearing deposits 6,563,160 6,563,160 6,596,289 6,596,289  Other time deposits 1,798,431 1,816,705 1,841,315 1,857,506  Federal funds purchased and securities  sold under agreement to repurchase  and other short-term borrowings 1,046,044 1,044,525 546,002 545,002  Long-term debt and other borrowings 30,000 31,413 542,888 547,273   Derivative instruments:  Forward commitments to sell fixed rate  mortgage loans 286 286 2,903 2,903  Commitments to fund fixed rate  mortgage loans 3,549 3,549 3,362 3,362  Interest rate swap position to receive 4,301 4,301 9,061 9,061  Interest rate swap position to pay (4,374) (4,374) (9,175) (9,175)

COMMITMENTS AND CONTINGENT LIABILITIES [Abstract]
COMMITMENTS AND CONTINGENT LIABILITIES	NOTE 16 – COMMITMENTS AND CONTINGENT LIABILITIES  The nature of the Company’s business ordinarily results in a certain amount of claims, litigation, investigations and legal and administrative cases and proceedings. Although the Company and its subsidiaries have developed policies and procedures to minimize the impact of legal noncompliance and other disputes, and endeavored to pro cure reasonable amounts of insurance coverage, litigation and regulatory actions present an ongoing risk. The Company and its subsidiaries are engaged in lines of business that are heavily regulated and involve a large volume of financial transactions and potential transactions with numerous customers or applicants, and the Company is a public company with a large number of shareholders. From time to time, borrowers, customers, shareholders, former employees and other third parties have brought actions against the Company or its subsidiaries, in some cases claiming substantial damages. Financial services companies are subject to the risk of class action litigation , and, from time to time, the Company and its subsidiaries are subject to such actions brought against it. Additionally, the Bank is, and management expects it to be, engaged in a number of foreclosure proceedings and other collection actions as part of its lending and leasing collections activities, which, from time to time, have resulted in counterclaims against the Bank. Various legal proceedings have arisen and may arise in the future out of claims against entities to which the Company is a successor as a result of business combinations. The Company and its subsidiaries may also be subject to enforcement actions by federal or state regulators , including the FDIC, the Consumer Financial Protection Bureau (the “CFPB”), the Department of Justice (the “DOJ”), state attorneys general and the Mississippi Department of Banking and Consumer Finance. When and as the Company determines it has meritorious defenses to the claims asserted, it vigorously defends against such claims. The Company will consider settlement of claims when, in management’s judgment and in consultation with counsel, it is in the best interests of the Company to do so. The Company cannot predict with certainty the cost of defense, the cost of prosecution or the ultimate outcome of litigation and other proceedings filed by or against it, its directors, management or employees, including remedies or damage awards. On at least a quarterly basis, the Company assesses its liabilities and contingencies in connection with outstanding legal proceedings as well as certain threatened claims (which are not considered incidental to the ordinary conduct of the Company’s business) utilizing the latest and most reliable information available. For matters where a loss is not probable or the amount of the loss cannot be estimated, no accrual is established. For matters where it is probable the Company will incur a loss and the amount can be reasonably estimated, the Company establishes an accrual for the loss. Once established, the accrual is adjusted periodically to reflect any relevant developments. The actual cost of any outstanding legal proceedings and the potential loss, however, may turn out to be substantially higher than the amount accrued. Further, the Company’s insurance policies have deductibles , and they will likely not cover all such litigation, other proceedings or claims, or the related costs of defense. While the final outcome of any legal proceedings is inherently uncertain, based on the information available, advice of counsel and available insurance coverage, if applicable, management believes that the litigation-related expense of $2.9 million accrued as of September 30, 2017, which excludes amounts reserved for regulatory settlement expenses discussed below, is adequate and that any incremental liability arising from the Company’s legal proceedings and threatened claims, including the matters described herein and those otherwise arising in the ordinary course of business, will not have a material adverse effect on the Company's business or consolidated financial condition. It is possible, however, that future developments could result in an unfavorable outcome for or resolution of any one or more of the lawsuits in which the Company or its subsidiaries are defendants, which may be material to the Company’s results of operations for a particular fiscal period or periods. On July 31, 2014 the Company, its Chief Executive Officer and former Chief Financial Officer were named in a purported class-action lawsuit filed in the U.S. District Court for the Middle District of Tennessee on behalf of certain purchasers of the Company’s common stock. The complaint was subsequently amended to add the Company’s former President and Chief Operating Officer. The complaint alleges that the defendants made misleading statements concerning the Company’s expectation that it would be able to close two merger transactions within a specified time period and regarding the Company’s compliance with certain Bank Secrecy Act and anti-money laundering requirements. On July 10, 2015, the District Court granted in part and denied in part the defendants’ motion to dismiss, holding that the statements concerning the Company’s expectations about the closing of the mergers were “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act, were protected by the safe harbor provision of the Private Securities Litigation Reform Act of 1995, and thus were not actionable . Class certification was granted by the District Court on April 21, 2016, and a petition for immediate appeal of the class certification order was filed and was granted. The U.S. Sixth Circuit Court of Appeals vacated the class certification order and remanded the case to the District Court for further proceedings. On June 26, 2017 the District Court issued a Memorandum Opinion and signed an Order granting class certification. On July 10, 2017 the defendants again filed a Petition for Permission to Appeal Pursuant to Rule of Civil Procedure 23(f) in the U.S. Sixth Circuit Court of Appeals. The Rule 23(f) petition was denied and on October 2, 2017, the Bank sought en banc reconsideration of that ruling. The plaintiff seeks an unspecified amount of damages and awards of costs and attorneys’ fees and such other equitable relief as the District Court may deem just and proper. At this stage of the lawsuit, management cannot determine the probability of an unfavorable outcome to the Company as it is uncertain whether the second class certification order will withstand review and the exact amount of damages is uncertain. Although it is not possible to predict the ultimate resolution or financial liability with respect to the litigation, management is currently of the opinion that the outcome of this lawsuit will not have a material adverse effect on the Company’s business, consolidated financial position or results of operations. On June 29, 2016, the Bank, the CFPB and the DOJ agreed to a settlement set forth in a consent order (the “Consent Order”) related to the joint investigation by the CFPB and the DOJ of the Bank’s fair lending program during the period between January 1, 2011 and December 31, 2013. The Consent Order was signed by the United States District Court for the Northern District of Mississippi (the “District Court”) on July 25, 2016. In the first quarter of 2016, the Bank reserved $13.8 million to cover costs related to this matter, $10.3 million of which was reflected as regulatory settlement expense and $3.5 million of which was included in other noninterest expense. The settlement of this matter did not have a material financial impact on the second and third quarter 2016 financial results. For additional information regarding the terms of this settlement and the Consent Order, see the signed Consent Order and the Company’s Current Report on Form 8-K that was filed with the SEC on June 29, 2016 which are incorporated herein by reference.
