Consolidation, Policy [Policy Text Block]

The consolidated financial statements include the accounts of Simmons First National Corporation (the “Company”) and its subsidiaries. Significant intercompany accounts and transactions have been eliminated in consolidation.

All adjustments made to the unaudited financial statements were of a normal recurring nature. In the opinion of management, all adjustments necessary for a fair presentation of the results of interim periods have been made. Certain prior year amounts are reclassified to conform to current year classification. The consolidated balance sheet of the Company as of December 31, 2013, 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 2013 filed with the U.S. Securities and Exchange Commission (the “SEC”)

New Accounting Pronouncements, Policy [Policy Text Block]

Recently Issued Accounting Pronouncements

In July 2013, the FASB issued ASU 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (Topic 740). ASU 2013-11 requires an entity to present an unrecognized tax benefit, or portion thereof, in the statement of financial position as a reduction to a deferred tax asset for a net operating loss carryforward or a tax credit carryforward, with certain exceptions related to availability. The provisions of ASU 2013-11 became effective for the Company on January 1, 2014, and did not have a significant impact on the Company’s ongoing financial position or results of operations.

In January 2014, the FASB issued ASU 2014-04, Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure (Topic 310-40): Receivables – Troubled Debt Restructurings by Creditors. The objective of this guidance is to clarify when an in substance repossession or foreclosure occurs, that is, when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan receivable should be derecognized and the real estate property recognized. ASU 2014-04 states that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, ASU 2014-04 requires interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. ASU 2014-04 is effective for interim and annual reporting periods beginning after December 15, 2014. An entity can elect to adopt the amendments in this ASU using either a modified retrospective transition method or a prospective transition method. Early adoption is permitted. The Company is in the process of evaluating the impact of ASU 2014-04 on its financial statements.

In April 2014, the FASB issued ASU 2014-08, Reporting Discontinued Operations and Disclosures of Components of an Entity, which changes the criteria for determining which disposals can be presented as discontinued operations and modifies related disclosure requirements. The guidance applies prospectively to new disposals and new classifications of disposal groups as held for sale after the effective date. The standard is required to be adopted by public business entities in annual periods beginning on or after December 15, 2014, and interim periods within those annual periods. The Company will be required to adopt this ASU beginning with the quarter ending March 31, 2015. The adoption of ASU 2014-08 is not expected to have a significant impact on the Company’s ongoing financial position or results of operations.

There have been no other significant changes to the Company’s accounting policies from the 2013 Form 10-K. Presently, the Company is not aware of any other changes to the Accounting Standards Codification that will have a material impact on the Company’s present or future financial position or results of operations.

Business Combinations Policy [Policy Text Block]

Acquisition Accounting, Acquired Loans

The Company accounts for its acquisitions under ASC Topic 805, Business Combinations, which requires the use of the purchase method of accounting. All identifiable assets acquired, including loans, are recorded at fair value. No allowance for loan losses related to the acquired loans is recorded on the acquisition date as the fair value of the loans acquired incorporates assumptions regarding credit risk. Loans acquired are recorded at fair value in accordance with the fair value methodology prescribed in ASC Topic 820, exclusive of the shared-loss agreements with the FDIC. The fair value estimates associated with the loans include estimates related to expected prepayments and the amount and timing of undiscounted expected principal, interest and other cash flows.

The Company evaluates loans acquired in accordance with the provisions of ASC Topic 310-20, Nonrefundable Fees and Other Costs. The fair value discount on these loans is 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 evaluates purchased impaired loans in accordance with the provisions of ASC Topic 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality. Purchased loans are considered impaired if there is evidence of credit deterioration since origination and if it is probable that not all contractually required payments will be collected.

The Company evaluates all of the loans purchased in conjunction with its FDIC-assisted transactions in accordance with the provisions of ASC Topic 310-30. All loans acquired in the FDIC transactions, both covered and not covered, were deemed to be impaired loans. All loans acquired, whether or not covered by FDIC loss share agreements, are considered impaired if there is evidence of credit deterioration since origination and if it is probable that not all contractually required payments will be collected.

For impaired loans accounted for under ASC Topic 310-30, we continue to estimate cash flows expected to be collected on pools of loans sharing common risk characteristics, which are treated in the aggregate when applying various valuation techniques. We evaluate at each balance sheet date whether the present value of our pools of loans determined using the effective interest rates has decreased significantly and if so, recognize a provision for loan loss in our consolidated statement of income. For any significant increases in cash flows expected to be collected, we adjust the amount of accretable yield recognized on a prospective basis over the pool’s remaining life.

Deteriorated Loans Transferred in, Policy [Policy Text Block]

Covered Loans and Related Indemnification Asset

Because the FDIC will reimburse us for certain losses incurred on certain acquired loans, an indemnification asset is recorded at fair value at the acquisition date. The indemnification asset is recognized at the same time as the indemnified loans, and measured on the same basis, subject to collectability or contractual limitations. The shared-loss agreements on the acquisition date reflect the reimbursements expected to be received from the FDIC, using an appropriate discount rate, which reflects counterparty credit risk and other uncertainties.

The shared-loss agreements continue to be measured on the same basis as the related indemnified loans, as prescribed by ASC Topic 805. Deterioration in the credit quality of the loans (immediately recorded as an adjustment to the allowance for loan losses) would immediately increase the basis of the shared-loss agreements, with the offset recorded through the consolidated statement of income. Increases in the credit quality or cash flows of loans (reflected as an adjustment to yield and accreted into income over the remaining life of the loans) decrease the basis of the shared-loss agreements, with such decrease being accreted into income over 1) the same period or 2) the life of the shared-loss agreements, whichever is shorter. Loss assumptions used in the basis of the indemnified loans are consistent with the loss assumptions used to measure the indemnification asset. Fair value accounting incorporates into the fair value of the indemnification asset an element of the time value of money, which is accreted back into income over the life of the shared-loss agreements.

Upon the determination of an incurred loss the indemnification asset will be reduced by the amount owed by the FDIC. A corresponding, claim receivable is recorded until cash is received from the FDIC. For further discussion of the Company’s acquisition and loan accounting, see Note 5, Loans Acquired.

Earnings Per Share, Policy [Policy Text Block]

Earnings Per Share (“EPS”)

Basic EPS is computed by dividing reported net income by weighted average number of common shares outstanding during each period. Diluted EPS is computed by dividing reported net income by the weighted average common shares and all potential dilutive common shares outstanding during the period.

Following is the computation of per share earnings for the three and six months ended June 30, 2014 and 2013:

	Three Months Ended June 30,				Six Months Ended June 30,
(In thousands, except per share data)	2014		2013		2014		2013
Net income	$	9,908	$	6,576	$	14,261	$	12,513

Average common shares outstanding		16,318		16,415		16,294		16,466
Average potential dilutive common shares		43		3		43		3
Average diluted common shares		16,361		16,418		16,337		16,469

Basic earnings per share	$	0.61	$	0.40	$	0.88	$	0.76
Diluted earnings per share	$	0.60	$	0.40	$	0.87	$	0.76

Stock options to purchase 138,528 shares for the three and six months ended June 30, 2013 were not included in the diluted EPS calculation because the exercise price of those options exceeded the average market price.

This accounting policy may include a general discussion of the purchase method or acquisition method of accounting (including for example, the treatment accorded contingent consideration, the identification of assets and liabilities, the purchase price allocation process, how the fair values of acquired assets and liabilities are determined) and the entity's specific application thereof. An entity that acquires another entity in a leveraged buyout transaction generally discloses the accounting policy followed by the acquiring entity in determining the basis used to value its interest in the acquired entity, and the rationale for that accounting policy.
