Significant Accounting Policies [Text Block]	NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations ServisFirst Bancshares, Inc. (the “Company”) was formed on August 16, 2007 May 2005. 1, 1, 10. Reclassification Certain amounts reported in prior years have been reclassified to conform to the current year’s presentation. These reclassifications had no Basis of Presentation and Accounting Estimates To prepare consolidated financial statements in conformity with U.S. generally accepted accounting principles, management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and future results could differ. The allowance for loan losses, valuation of foreclosed real estate, goodwill and other intangible assets and fair values of financial instruments are particularly subject to change. All numbers are in thousands except share and per share data. Cash, Due from Banks, Interest-Bearing Balances due from Financial Institutions Cash and due from banks includes cash on hand, cash items in process of collection, amounts due from banks and interest bearing balances due from financial institutions. For purposes of cash flows, cash and cash equivalents include cash and due from banks and federal funds sold. Generally, federal funds are purchased and sold for one The Bank is required to maintain reserve balances in cash or on deposit with the Federal Reserve Bank based on a percentage of deposits. The total of those reserve balances was approximately $51.0 December 31, 2018 $51.8 December 31, 2017. Debt Securities Securities are classified as available-for-sale when they might be sold before maturity. Unrealized holding gains and losses, net of tax, on securities available for sale are reported as a net amount in a separate component of stockholders’ equity until realized. Gains and losses on the sale of securities available for sale are determined using the specific-identification method. The amortization of premiums and the accretion of discounts are recognized in interest income using methods approximating the interest method over the period to maturity. Declines in the fair value of available-for-sale securities below their cost that are deemed to be other than temporary are reflected in earnings as realized losses. Securities are classified as held-to-maturity when the Company has the positive intent and ability to hold the securities to maturity. Held-to-maturity securities are reported at amortized cost. In determining the existence of other-than-temporary impairment losses, management considers ( 1 2 3 Investments in Equity Securities Carried at Cost Investments in restricted equity securities without a readily determinable market value are carried at cost. Mortgage Loans Held for Sale The Company classifies certain residential mortgage loans as held for sale. Typically mortgage loans held for sale are sold to a third not In the course of originating mortgage loans and selling those loans in the secondary market, the Company makes various representations and warranties to the purchaser of the mortgage loans. Each loan is underwritten using government agency guidelines. Any exceptions noted during this process are remedied prior to sale. These representations and warranties also apply to underwriting the real estate appraisal opinion of value for the collateral securing these loans. Under the representations and warranties, failure by the Company to comply with the underwriting and/or appraisal standards could result in the Company being required to repurchase the mortgage loan or to reimburse the investor for losses incurred (make whole requests) if such failure cannot be cured by the Company within the specified period following discovery. The Company continues to experience an insignificant level of investor repurchase demands. There were no December 31, 2018 2017. Loans Loans are reported at unpaid principal balances, less unearned fees and the allowance for loan losses. Interest on all loans is recognized as income based upon the applicable rate applied to the daily outstanding principal balance of the loans. Interest income on nonaccrual loans is recognized on a cash basis or cost recovery basis until the loan is returned to accrual status. A loan may six not one The accrual of interest on loans is discontinued when there is a significant deterioration in the financial condition of the borrower and full repayment of principal and interest is not 90 not A loan is considered impaired when it is probable the Company will be unable to collect all principal and interest payments due according to the contractual terms of the loan agreement. Individually identified impaired loans are measured based on the present value of expected payments using the loan’s original effective rate as the discount rate, the loan’s observable market price, or the fair value of the collateral if the loan is collateral dependent. If the recorded investment in the impaired loan exceeds the measure of fair value, a valuation allowance may Impaired loans also include troubled debt restructurings (“TDRs”). In the normal course of business management grants concessions to borrowers, which would not may six Acquired loans are recorded at fair value at the date of acquisition, and accordingly no 1 not Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent significant increases in cash flows result in a reversal of the provision for loan losses to the extent of prior provisions or a reclassification of amount from non-accretable difference to accretable yield, with a positive impact on the accretion of interest income in future periods. Acquired performing loans are accounted for using the contractual cash flows method of recognizing discount accretion based on the acquired loans’ contractual cash flows. Acquired performing loans are recorded as of the acquisition date at fair value, considering credit and other risks, with no 1 Allowance for Loan Losses The allowance for loan losses is maintained at a level which, in management’s judgment, is adequate to absorb credit losses inherent in the loan portfolio. The amount of the allowance is based on management’s evaluation of the collectability of the loan portfolio, including the nature of the portfolio, credit concentrations, trends in historical loss experience, specific impaired loans, economic conditions, and other risks inherent in the portfolio. Allowances for impaired loans are generally determined based on collateral values or the present value of the estimated cash flows. The allowance is increased by a provision for loan losses, which is charged to expense, and reduced by charge-offs, net of recoveries. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the allowance for losses on loans. Such agencies may Foreclosed Real Estate Foreclosed real estate includes both formally foreclosed property and in-substance foreclosed property. At the time of foreclosure, foreclosed real estate is recorded at fair value less cost to sell, which becomes the property’s new basis.

Disclosure of Variable Interest Entities [Text Block]	NOTE 6.

These SPEs are typically structured as VIEs and are thus subject to consolidation by the reporting enterprise that absorbs the majority of the economic risks and rewards of the VIE. To determine whether it must consolidate a VIE, the Company analyzes the design of the VIE to identify the sources of variability within the VIE, including an assessment of the nature of risks created by the assets and other contractual obligations of the VIE, and determines whether it will absorb a majority of that variability. The Company has invested in limited partnerships as a funding investor. The partnerships are single purpose entities that lend money to real estate investors for the purpose of acquiring and operating, or rehabbing, commercial property.

Basis of Accounting, Policy and Use of Estimates [Policy Text Block]	Basis of Presentation and Accounting Estimates To prepare consolidated financial statements in conformity with U.S. generally accepted accounting principles, management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and future results could differ. The allowance for loan losses, valuation of foreclosed real estate, goodwill and other intangible assets and fair values of financial instruments are particularly subject to change. All numbers are in thousands except share and per share data.
Cash Due From Banks Interest Bearing Balances Due From Financial Institutions [Policy Text Block]	Cash, Due from Banks, Interest-Bearing Balances due from Financial Institutions Cash and due from banks includes cash on hand, cash items in process of collection, amounts due from banks and interest bearing balances due from financial institutions.

Investment, Policy [Policy Text Block]	Debt Securities Securities are classified as available-for-sale when they might be sold before maturity. Unrealized holding gains and losses, net of tax, on securities available for sale are reported as a net amount in a separate component of stockholders’ equity until realized. Gains and losses on the sale of securities available for sale are determined using the specific-identification method. The amortization of premiums and the accretion of discounts are recognized in interest income using methods approximating the interest method over the period to maturity. Declines in the fair value of available-for-sale securities below their cost that are deemed to be other than temporary are reflected in earnings as realized losses. Securities are classified as held-to-maturity when the Company has the positive intent and ability to hold the securities to maturity. Held-to-maturity securities are reported at amortized cost. In determining the existence of other-than-temporary impairment losses, management considers ( 1 2 3
Cost Method Investments, Policy [Policy Text Block]	Investments in Equity Securities Carried at Cost Investments in restricted equity securities without a readily determinable market value are carried at cost.
Loans and Leases Receivable, Mortgage Banking Activities, Policy [Policy Text Block]	Mortgage Loans Held for Sale The Company classifies certain residential mortgage loans as held for sale. Typically mortgage loans held for sale are sold to a third not In the course of originating mortgage loans and selling those loans in the secondary market, the Company makes various representations and warranties to the purchaser of the mortgage loans. Each loan is underwritten using government agency guidelines. Any exceptions noted during this process are remedied prior to sale. These representations and warranties also apply to underwriting the real estate appraisal opinion of value for the collateral securing these loans. Under the representations and warranties, failure by the Company to comply with the underwriting and/or appraisal standards could result in the Company being required to repurchase the mortgage loan or to reimburse the investor for losses incurred (make whole requests) if such failure cannot be cured by the Company within the specified period following discovery. The Company continues to experience an insignificant level of investor repurchase demands. There were no December 31, 2018 2017.
Policy Loans Receivable, Policy [Policy Text Block]	Loans Loans are reported at unpaid principal balances, less unearned fees and the allowance for loan losses. Interest on all loans is recognized as income based upon the applicable rate applied to the daily outstanding principal balance of the loans. Interest income on nonaccrual loans is recognized on a cash basis or cost recovery basis until the loan is returned to accrual status. A loan may six not one The accrual of interest on loans is discontinued when there is a significant deterioration in the financial condition of the borrower and full repayment of principal and interest is not 90 not A loan is considered impaired when it is probable the Company will be unable to collect all principal and interest payments due according to the contractual terms of the loan agreement. Individually identified impaired loans are measured based on the present value of expected payments using the loan’s original effective rate as the discount rate, the loan’s observable market price, or the fair value of the collateral if the loan is collateral dependent. If the recorded investment in the impaired loan exceeds the measure of fair value, a valuation allowance may Impaired loans also include troubled debt restructurings (“TDRs”). In the normal course of business management grants concessions to borrowers, which would not may six Acquired loans are recorded at fair value at the date of acquisition, and accordingly no 1 not Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent significant increases in cash flows result in a reversal of the provision for loan losses to the extent of prior provisions or a reclassification of amount from non-accretable difference to accretable yield, with a positive impact on the accretion of interest income in future periods. Acquired performing loans are accounted for using the contractual cash flows method of recognizing discount accretion based on the acquired loans’ contractual cash flows. Acquired performing loans are recorded as of the acquisition date at fair value, considering credit and other risks, with no 1
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	Allowance for Loan Losses The allowance for loan losses is maintained at a level which, in management’s judgment, is adequate to absorb credit losses inherent in the loan portfolio. The amount of the allowance is based on management’s evaluation of the collectability of the loan portfolio, including the nature of the portfolio, credit concentrations, trends in historical loss experience, specific impaired loans, economic conditions, and other risks inherent in the portfolio. Allowances for impaired loans are generally determined based on collateral values or the present value of the estimated cash flows. The allowance is increased by a provision for loan losses, which is charged to expense, and reduced by charge-offs, net of recoveries. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the allowance for losses on loans. Such agencies may
Loans and Leases Receivable, Real Estate Acquired Through Foreclosure, Policy [Policy Text Block]	Foreclosed Real Estate Foreclosed real estate includes both formally foreclosed property and in-substance foreclosed property. At the time of foreclosure, foreclosed real estate is recorded at fair value less cost to sell, which becomes the property’s new basis. Any write downs based on the asset’s fair value at date of acquisition are charged to the allowance for loan losses. After foreclosure, these assets are carried at the lower of their new cost basis or fair value less cost to sell. Costs incurred in maintaining foreclosed real estate and subsequent adjustments to the carrying amount of the property are included in other operating expenses.
Property, Plant and Equipment, Policy [Policy Text Block]	Premises and Equipment Premises and equipment are stated at cost less accumulated depreciation. Expenditures for additions and major improvements that significantly extend the useful lives of the assets are capitalized. Expenditures for repairs and maintenance are charged to expense as incurred. Assets which are disposed of are removed from the accounts and the resulting gains or losses are recorded in operations. Depreciation is calculated on a straight-line basis over the estimated useful lives of the related assets ( 3 39.5 Leasehold improvements are amortized on a straight-line basis over the lesser of the lease terms or the estimated useful lives of the improvements.

The Company’s obligations under forward contracts consist of “best effort” commitments to deliver mortgage loans originated in the secondary market at a future date. Interest rate lock commitments related to loans that are originated for later sale are classified as derivatives.
