Significant Accounting Policies [Text Block]	NOTE 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations and Principles of Consolidation Simmons First National Corporation (the “Company”) is primarily engaged in providing a full range of banking services to individual and corporate customers through its subsidiaries and their branch banks with offices in Arkansas, Kansas, Missouri and Tennessee. The Company is subject to competition from other financial institutions. The Company also is subject to the regulation of certain federal and state agencies and undergoes periodic examinations by those regulatory authorities. The consolidated financial statements include the accounts of Simmons First National Corporation and its subsidiaries. Significant intercompany accounts and transactions have been eliminated in consolidation. Operating Segments The Company is organized on a regional basis upon which management makes decisions regarding how to allocate resources and assess performance. Each of the regions provides a group of similar community banking services, including such products and services as loans; time deposits, checking and savings accounts; personal and corporate trust services; credit cards; investment management; insurance; and securities and investment services. Loan products include consumer, real estate, commercial, agricultural, equipment and SBA lending. The individual bank regions have similar operating and economic characteristics and have been reported as one The Company also considers its trust, investment and insurance services to be operating segments. Information on these segments is not reported separately since they do not meet the quantitative thresholds under ASC Topic 280 10 50 12. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses, the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans and the valuation of covered loans and related indemnification asset. In connection with the determination of the allowance for loan losses and the valuation of foreclosed assets, management obtains independent appraisals for significant properties. Reclassifications Various items within the accompanying consolidated financial statements for previous years have been reclassified to provide more comparative information. These reclassifications had no effect on net earnings. Cash Equivalents The Company considers all liquid investments with original maturities of three Investment Securities Held-to-maturity securities, which include any security for which the Company has the positive intent and ability to hold until maturity, are carried at historical cost adjusted for amortization of premiums and accretion of discounts. Premiums and discounts are amortized and accreted, respectively, to interest income using the constant yield method over the period to maturity. Available-for-sale securities, which include any security for which the Company has no immediate plan to sell but which may Trading securities, which include any security held primarily for near-term sale, are carried at fair value. Gains and losses on trading securities are included in other income. The Company applies accounting guidance related to recognition and presentation of other-than-temporary impairment under ASC Topic 320 10. As a result of this guidance, the Company’s consolidated statements of income reflect the full impairment (that is, the difference between the security’s amortized cost basis and fair value) on debt securities that the Company intends to sell or would more likely than not be required to sell before the expected recovery of the amortized cost basis. For available-for-sale and held-to-maturity debt securities that management has no intent to sell and believes that it more likely than not will not be required to sell prior to recovery, only the credit loss component of the impairment is recognized in earnings, while the noncredit loss is recognized in accumulated other comprehensive income. The credit loss component recognized in earnings is identified as the amount of principal cash flows not expected to be received over the remaining term of the security as projected based on cash flow projections. Mortgage Loans Held For Sale Mortgage loans held for sale are carried at the lower of cost or fair value, determined using an aggregate basis. Write-downs to fair value are recognized as a charge to earnings at the time the decline in value occurs. Forward commitments to sell mortgage loans are acquired to reduce market risk on mortgage loans in the process of origination and mortgage loans held for sale. The forward commitments acquired by the Company for mortgage loans in process of origination are not mandatory forward commitments. These commitments are structured on a best efforts basis; therefore, the Company is not required to substitute another loan or to buy back the commitment if the original loan does not fund. Typically, the Company delivers the mortgage loans within a few days after the loans are funded. These commitments are derivative instruments and their fair values at December 31, 2016 2015 Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-offs are reported at their outstanding principal adjusted for any loans charged off, the allowance for loan losses and any unamortized deferred fees or costs on originated loans and unamortized premiums or discounts on purchased loans. For loans amortized at cost, interest income is accrued based on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, as well as premiums and discounts, are deferred and amortized as a level yield adjustment over the respective term of the loan. The accrual of interest on loans, except on certain government guaranteed loans, is discontinued at the time the loan is 90 Discounts and premiums on purchased residential real estate loans are amortized to income using the interest method over the remaining period to contractual maturity, adjusted for anticipated prepayments. Discounts and premiums on purchased consumer loans are recognized over the expected lives of the loans using methods that approximate the interest method. For discussion of the Company’s accounting for acquired loans, see Acquisition Accounting, Covered Loans and Related Indemnification Asset later in this section. Allowance for Loan Losses The allowance for loan losses is management’s estimate of probable losses in the loan portfolio. Loan losses are charged against the allowance when management believes the uncollectability of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Allocations to the allowance for loan losses are categorized as either general reserves or specific reserves. The allowance for loan losses is calculated monthly based on management’s assessment of several factors such as (1) (2) (3) (4) (5) (6) (7) (8) one four Specific reserves are provided on loans that are considered impaired when it is probable that we will not receive all amounts due according to the contractual terms of the loan, including scheduled principal and interest payments. This includes loans that are delinquent 90 90 Management’s evaluation of the allowance for loan losses is inherently subjective as it requires material estimates. The actual amounts of loan losses realized in the near term could differ from the amounts estimated in arriving at the allowance for loan losses reported in the financial statements. Reserve for Unfunded Commitments In addition to the allowance for loan losses, the Company has established a reserve for unfunded commitments, classified in other liabilities. This reserve is maintained at a level sufficient to absorb losses arising from unfunded loan commitments. The adequacy of the reserve for unfunded commitments is determined monthly based on methodology similar to the Company’s methodology for determining the allowance for loan losses. Net adjustments to the reserve for unfunded commitments are included in other non-interest expense. Acquisition Accounting, Acquired Loans The Company accounts for its acquisitions under ASC Topic 805, Business Combinations 820. The Company evaluates non-impaired loans acquired in accordance with the provisions of ASC Topic 310 20, Nonrefundable Fees and Other Costs 310 30, Loans and Debt Securities Acquired with Deteriorated Credit Quality For impaired loans accounted for under ASC Topic 310 30, Covered Loans and Related Indemnification Asset In September 2015, 2010 2012 four Under the terms of the agreement, the FDIC made a net payment of $2,368,000 one $7,476,000. For further discussion of our acquisition and loan accounting, see Note 2, 5, Premises and Equipment Depreciable assets are stated at cost less accumulated depreciation. Depreciation is charged to expense using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are capitalized and amortized by the straight-line method over the terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter. Premises Held for Sale The Company records premises held for sale at the lower of (1) (2) Foreclosed Assets Held For Sale Assets acquired by foreclosure or in settlement of debt and held for sale are valued at estimated fair value as of the date of foreclosure, and a related valuation allowance is provided for estimated costs to sell the assets. Management evaluates the value of foreclosed assets held for sale periodically and increases the valuation allowance for any subsequent declines in fair value. Changes in the valuation allowance are charged or credited to other expense. Bank Owned Life Insurance The Company maintains bank-owned life insurance policies on certain current and former employees and directors, which are recorded at their cash surrender values as determined by the insurance carriers. The appreciation in the cash surrender value of the policies is recognized as a component of non-interest income in the Company’s consolidated statements of income. Goodwill and Intangible Assets Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. Other intangible assets represent purchased assets that also lack physical substance but can be separately distinguished from goodwill because of contractual or other legal rights or because the asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset or liability. The Company performs an annual goodwill impairment test, and more frequently if circumstances warrant, in accordance with ASC Topic 350, Intangibles – Goodwill and Other 350 may Derivative Financial Instruments The Company may $99.2 December 31, 2016, $61.3 December 31, 2015. Securities Sold Under Agreements to Repurchase The Company sells securities under agreements to repurchase to meet customer needs for sweep accounts. At the point funds deposited by customers become investable, those funds are used to purchase securities owned by the Company and held in its general account with the designation of Customers’ Securities. A third Bankcard Fee Income Periodic bankcard fees, net of direct origination costs, are recognized as revenue on a straight-line basis over the period the fee entitles the cardholder to use the card. Income Taxes The Company accounts for income taxes in accordance with income tax accounting guidance in ASC Topic 740, Income Taxes two Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term more likely than not means a likelihood of more than 50 50 The Company files consolidated income tax returns with its subsidiaries. Earnings Per Share Basic earnings per share are computed based on the weighted average number of shares outstanding during each year. Diluted earnings per share are computed using the weighted average common shares and all potential dilutive common shares outstanding during the period. The computation of per share earnings is as follows: (In thousands, except per share data) 2016 2015 2014 Net income available to common shareholders $ 96,790 $ 74,107 $ 35,688 Average common shares outstanding 30,646 28,084 16,879 Average potential dilutive common shares 318 126 43 Average diluted common shares 30,964 28,210 16,922 Basic earnings per share $ 3.16 $ 2.64 $ 2.11 Diluted earnings per share $ 3.13 $ 2.63 $ 2.11 There were no stock options excluded from the earnings per share calculation due to the related exercise price exceeding the average market price for the years ended December 31, 2016, 2015 2014. Stock-Based Compensation The Company has adopted various stock-based compensation plans. The plans provide for the grant of incentive stock options, nonqualified stock options, stock appreciation rights and bonus stock awards. Pursuant to the plans, shares are reserved for future issuance by the Company, upon exercise of stock options or awarding of bonus shares granted to directors, officers and other key employees.

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.

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.

During the 2014 $954,000 $0.4 December 31, 2014. 2015 2016. $954,000 5, 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.

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.

Expected volatility is based on historical volatility of the Company’s stock and other factors. The Company uses historical data to estimate option exercise and employee termination within the valuation model. The expected term of options granted is derived from the output of the option valuation model and represents the period of time that options granted are expected to be outstanding. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. Forfeitures are estimated at the time of grant, and are based partially on historical experience.

Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	Nature of Operations and Principles of Consolidation Simmons First National Corporation (the “Company”) is primarily engaged in providing a full range of banking services to individual and corporate customers through its subsidiaries and their branch banks with offices in Arkansas, Kansas, Missouri and Tennessee. The Company is subject to competition from other financial institutions. The Company also is subject to the regulation of certain federal and state agencies and undergoes periodic examinations by those regulatory authorities. The consolidated financial statements include the accounts of Simmons First National Corporation and its subsidiaries. Significant intercompany accounts and transactions have been eliminated in consolidation.
Segment Reporting, Policy [Policy Text Block]	Operating Segments The Company is organized on a regional basis upon which management makes decisions regarding how to allocate resources and assess performance. Each of the regions provides a group of similar community banking services, including such products and services as loans; time deposits, checking and savings accounts; personal and corporate trust services; credit cards; investment management; insurance; and securities and investment services. Loan products include consumer, real estate, commercial, agricultural, equipment and SBA lending. The individual bank regions have similar operating and economic characteristics and have been reported as one The Company also considers its trust, investment and insurance services to be operating segments. Information on these segments is not reported separately since they do not meet the quantitative thresholds under ASC Topic 280 10 50 12.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses, the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans and the valuation of covered loans and related indemnification asset. In connection with the determination of the allowance for loan losses and the valuation of foreclosed assets, management obtains independent appraisals for significant properties.
Reclassification, Policy [Policy Text Block]	Reclassifications Various items within the accompanying consolidated financial statements for previous years have been reclassified to provide more comparative information. These reclassifications had no effect on net earnings.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash Equivalents The Company considers all liquid investments with original maturities of three
Investment, Policy [Policy Text Block]	Investment Securities Held-to-maturity securities, which include any security for which the Company has the positive intent and ability to hold until maturity, are carried at historical cost adjusted for amortization of premiums and accretion of discounts. Premiums and discounts are amortized and accreted, respectively, to interest income using the constant yield method over the period to maturity. Available-for-sale securities, which include any security for which the Company has no immediate plan to sell but which may Trading securities, which include any security held primarily for near-term sale, are carried at fair value. Gains and losses on trading securities are included in other income. The Company applies accounting guidance related to recognition and presentation of other-than-temporary impairment under ASC Topic 320 10. As a result of this guidance, the Company’s consolidated statements of income reflect the full impairment (that is, the difference between the security’s amortized cost basis and fair value) on debt securities that the Company intends to sell or would more likely than not be required to sell before the expected recovery of the amortized cost basis. For available-for-sale and held-to-maturity debt securities that management has no intent to sell and believes that it more likely than not will not be required to sell prior to recovery, only the credit loss component of the impairment is recognized in earnings, while the noncredit loss is recognized in accumulated other comprehensive income. The credit loss component recognized in earnings is identified as the amount of principal cash flows not expected to be received over the remaining term of the security as projected based on cash flow projections.
Loans and Leases Receivable, Mortgage Banking Activities, Policy [Policy Text Block]	Mortgage Loans Held For Sale Mortgage loans held for sale are carried at the lower of cost or fair value, determined using an aggregate basis. Write-downs to fair value are recognized as a charge to earnings at the time the decline in value occurs. Forward commitments to sell mortgage loans are acquired to reduce market risk on mortgage loans in the process of origination and mortgage loans held for sale. The forward commitments acquired by the Company for mortgage loans in process of origination are not mandatory forward commitments. These commitments are structured on a best efforts basis; therefore, the Company is not required to substitute another loan or to buy back the commitment if the original loan does not fund. Typically, the Company delivers the mortgage loans within a few days after the loans are funded. These commitments are derivative instruments and their fair values at December 31, 2016 2015
Finance, Loan and Lease Receivables, Held-for-investment, Policy [Policy Text Block]	Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-offs are reported at their outstanding principal adjusted for any loans charged off, the allowance for loan losses and any unamortized deferred fees or costs on originated loans and unamortized premiums or discounts on purchased loans. For loans amortized at cost, interest income is accrued based on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, as well as premiums and discounts, are deferred and amortized as a level yield adjustment over the respective term of the loan. The accrual of interest on loans, except on certain government guaranteed loans, is discontinued at the time the loan is 90 Discounts and premiums on purchased residential real estate loans are amortized to income using the interest method over the remaining period to contractual maturity, adjusted for anticipated prepayments. Discounts and premiums on purchased consumer loans are recognized over the expected lives of the loans using methods that approximate the interest method. For discussion of the Company’s accounting for acquired loans, see Acquisition Accounting, Covered Loans and Related Indemnification Asset later in this section.
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	Allowance for Loan Losses The allowance for loan losses is management’s estimate of probable losses in the loan portfolio. Loan losses are charged against the allowance when management believes the uncollectability of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Allocations to the allowance for loan losses are categorized as either general reserves or specific reserves. The allowance for loan losses is calculated monthly based on management’s assessment of several factors such as (1) (2) (3) (4) (5) (6) (7) (8) one four Specific reserves are provided on loans that are considered impaired when it is probable that we will not receive all amounts due according to the contractual terms of the loan, including scheduled principal and interest payments. This includes loans that are delinquent 90 90 Management’s evaluation of the allowance for loan losses is inherently subjective as it requires material estimates. The actual amounts of loan losses realized in the near term could differ from the amounts estimated in arriving at the allowance for loan losses reported in the financial statements.
Commitments and Contingencies, Policy [Policy Text Block]	Reserve for Unfunded Commitments In addition to the allowance for loan losses, the Company has established a reserve for unfunded commitments, classified in other liabilities. This reserve is maintained at a level sufficient to absorb losses arising from unfunded loan commitments. The adequacy of the reserve for unfunded commitments is determined monthly based on methodology similar to the Company’s methodology for determining the allowance for loan losses. Net adjustments to the reserve for unfunded commitments are included in other non-interest expense.
Business Combinations Policy [Policy Text Block]	Acquisition Accounting, Acquired Loans The Company accounts for its acquisitions under ASC Topic 805, Business Combinations 820. The Company evaluates non-impaired loans acquired in accordance with the provisions of ASC Topic 310 20, Nonrefundable Fees and Other Costs 310 30, Loans and Debt Securities Acquired with Deteriorated Credit Quality For impaired loans accounted for under ASC Topic 310 30,
Deteriorated Loans Transferred in, Policy [Policy Text Block]	Covered Loans and Related Indemnification Asset In September 2015, 2010 2012 four Under the terms of the agreement, the FDIC made a net payment of $2,368,000 one $7,476,000. For further discussion of our acquisition and loan accounting, see Note 2, 5,
Property, Plant and Equipment, Policy [Policy Text Block]	Premises and Equipment Depreciable assets are stated at cost less accumulated depreciation. Depreciation is charged to expense using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are capitalized and amortized by the straight-line method over the terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter.
Premises Held-for-sale, Policy [Policy Text Block]	Premises Held for Sale The Company records premises held for sale at the lower of (1) (2)
Real Estate Held for Development and Sale, Policy [Policy Text Block]	Foreclosed Assets Held For Sale Assets acquired by foreclosure or in settlement of debt and held for sale are valued at estimated fair value as of the date of foreclosure, and a related valuation allowance is provided for estimated costs to sell the assets. Management evaluates the value of foreclosed assets held for sale periodically and increases the valuation allowance for any subsequent declines in fair value. Changes in the valuation allowance are charged or credited to other expense.
Bank Owned Life Insurance [Policy Text Block]	Bank Owned Life Insurance The Company maintains bank-owned life insurance policies on certain current and former employees and directors, which are recorded at their cash surrender values as determined by the insurance carriers. The appreciation in the cash surrender value of the policies is recognized as a component of non-interest income in the Company’s consolidated statements of income.
Goodwill and Intangible Assets, Policy [Policy Text Block]	Goodwill and Intangible Assets Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. Other intangible assets represent purchased assets that also lack physical substance but can be separately distinguished from goodwill because of contractual or other legal rights or because the asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset or liability. The Company performs an annual goodwill impairment test, and more frequently if circumstances warrant, in accordance with ASC Topic 350, Intangibles – Goodwill and Other 350 may
Derivatives, Policy [Policy Text Block]	Derivative Financial Instruments The Company may $99.2 December 31, 2016, $61.3 December 31, 2015.
Repurchase and Resale Agreements Policy [Policy Text Block]	Securities Sold Under Agreements to Repurchase The Company sells securities under agreements to repurchase to meet customer needs for sweep accounts. At the point funds deposited by customers become investable, those funds are used to purchase securities owned by the Company and held in its general account with the designation of Customers’ Securities. A third
Investment Banking Fees, Policy [Policy Text Block]	Bankcard Fee Income Periodic bankcard fees, net of direct origination costs, are recognized as revenue on a straight-line basis over the period the fee entitles the cardholder to use the card.
Income Tax, Policy [Policy Text Block]	Income Taxes The Company accounts for income taxes in accordance with income tax accounting guidance in ASC Topic 740, Income Taxes two Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term more likely than not means a likelihood of more than 50 50 The Company files consolidated income tax returns with its subsidiaries.
Earnings Per Share, Policy [Policy Text Block]	Earnings Per Share Basic earnings per share are computed based on the weighted average number of shares outstanding during each year. Diluted earnings per share are computed using the weighted average common shares and all potential dilutive common shares outstanding during the period. The computation of per share earnings is as follows: (In thousands, except per share data) 2016 2015 2014 Net income available to common shareholders $ 96,790 $ 74,107 $ 35,688 Average common shares outstanding 30,646 28,084 16,879 Average potential dilutive common shares 318 126 43 Average diluted common shares 30,964 28,210 16,922 Basic earnings per share $ 3.16 $ 2.64 $ 2.11 Diluted earnings per share $ 3.13 $ 2.63 $ 2.11 There were no stock options excluded from the earnings per share calculation due to the related exercise price exceeding the average market price for the years ended December 31, 2016, 2015 2014.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock-Based Compensation The Company has adopted various stock-based compensation plans. The plans provide for the grant of incentive stock options, nonqualified stock options, stock appreciation rights and bonus stock awards. Pursuant to the plans, shares are reserved for future issuance by the Company, upon exercise of stock options or awarding of bonus shares granted to directors, officers and other key employees.
