Notes to Financial Statements
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	(1) Summary of Significant Accounting Policies Basis of Presentation The consolidated financial statements include the accounts of National Commerce Corporation (the “Company”) and its wholly-owned banking subsidiary, National Bank of Commerce (“NBC” or the “Bank”) and wholly-owned non-banking subsidiary, National Commerce Risk Management, Inc., a captive insurance company used to insure certain corporate risks. The consolidated financial statements also include the accounts of NBC’s majority-owned subsidiary, CBI Holding Company, LLC (“CBI”), which owns Corporate Billing, LLC (“Corporate Billing”). Corporate Billing is a transaction-based finance company headquartered in Decatur, Alabama that provides factoring, invoicing, collection and accounts receivable management services to transportation companies and automotive parts and service providers nationwide. The Bank provides a full range of commercial and consumer banking services throughout Alabama, central and northeast Florida and the Atlanta, Georgia metropolitan area. NBC is primarily regulated by the Office of the Comptroller of Currency (the “OCC”) and undergoes periodic examinations by the OCC. The Company is regulated by the Board of Governors of the Federal Reserve System (the “Federal Reserve”) and is also subject to periodic examinations by the Federal Reserve. The accounting principles followed by the Company and the method of applying these principles conform with accounting principles generally accepted in the United States of America (“GAAP”) and with general practices within the banking industry. In preparing financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts in the consolidated financial statements. Actual results could differ significantly from those estimates. Material estimates common to the banking industry that are particularly susceptible to significant change in the near term include, but are not limited 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 valuation allowances associated with the realization of deferred tax assets, which are based on future taxable income. Cash and Cash Equivalents Cash equivalents include amounts due from banks, interest-bearing deposits with the Federal Reserve Bank of Atlanta (“FRB”), Federal Home Loan Bank (“FHLB”) and correspondent banks, and federal funds sold. Generally, federal funds are sold for one December 31, 2016 2015, $8,139,000 $12,218,000, Investment Securities The Company classifies its securities in one three December 31, 2016, $26,329,000, $73,380,000. December 31, 2015, $27,458,000, $53,405,000. Available-for-sale securities are recorded at fair value. Held-to-maturity securities are recorded at cost, adjusted for the amortization or accretion of premiums or discounts. Unrealized holding gains and losses, net of the related tax effect, on securities available-for-sale are excluded from earnings and are reported as a separate component of shareholders’ equity until realized. Transfers of securities between categories are recorded at fair value at the date of transfer. Management evaluates investment securities for other-than-temporary impairment on a quarterly basis. A decline in the market value of any investment below cost that is deemed other-than-temporary is charged to earnings for the decline in value deemed to be credit-related, and a new cost basis in the security is established. The decline in value attributed to non-credit-related factors is recognized in other comprehensive income. Premiums and discounts are amortized or accreted over the life of the related securities as adjustments to the yield. Realized gains and losses are included in earnings and are derived using the specific identification method for determining the cost of securities sold. Other Investments Other investments include FRB stock, FHLB stock and other investments that do not have a readily determinable market value. These investments are carried at cost, which approximates fair value. Loans and Allowance for Loan Losses Loans are stated at the principal amount outstanding, net of the allowance for loan losses. Interest on loans is calculated by using the simple interest method on daily balances of the principal amount outstanding. Nonrefundable loan fees and costs incurred for loans are deferred and recognized in income over the life of the loans. A loan is considered impaired when, based on current information and events, it is probable that all amounts due according to the contractual terms of the loan agreement will not be collected. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, at the loan’s observable market price, or at the fair value of the collateral of the loan if the loan is collateral-dependent. Accrual of interest is discontinued on a loan when management believes, after considering economic and business conditions and collection efforts, that the borrower's financial condition is such that collection of interest is doubtful. When a loan is placed on nonaccrual status, previously accrued and uncollected interest is charged to interest income on loans. Generally, payments on nonaccrual loans are applied to principal. When a borrower has demonstrated the capacity to service the debt for a reasonable period of time, management may The allowance for loan losses is established through a provision for loan losses charged to expense. Loans are charged against the allowance for loan losses when management believes that the collectibility of the principal is unlikely. The allowance represents an amount that, in management’s judgment, will be adequate to absorb probable losses on existing loans that may Management’s judgment in determining the adequacy of the allowance is based on evaluations of the collectibility of loans. These evaluations take into consideration such factors as changes in the nature and volume of the loan portfolio, current economic conditions that may Management believes that the allowance for loan losses is adequate. While management uses available information to recognize losses on loans, future additions to the allowance may may Transfers of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) (2) (3) Mortgage Loans Held-for-Sale Prior to the year ended December 31, 2016, December 31, 2016, secondary In connection with mandatory delivery, the Company elected to record its mortgage loans held-for-sale at fair value. The fair value of committed residential loans held-for-sale is determined by outstanding commitments from investors, and the fair value of uncommitted loans is based on the current delivery prices in the secondary Premises and Equipment Premises and equipment are stated at cost less accumulated depreciation. Major additions and improvements are charged to the property accounts, while replacements, maintenance, and repairs that do not improve or extend the life of the respective assets are expensed currently. When property is retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts, and the resulting gain or loss, if any, is recognized. Depreciation expense is computed using the straight-line method over the following estimated useful lives: Useful Life (in years) Building and improvements 10 - 40 Furniture and equipment 5 - 10 Leasehold improvements 18 Computer equipment 3 - 5 Other Real Estate and Repossessed Assets Other real estate represents properties acquired through or in lieu of loan foreclosure and is initially recorded at fair value less estimated disposal costs. Costs of improvements are capitalized, whereas costs relating to holding other real estate and valuation adjustments are expensed. Revenue and expenses from operations and changes in the valuation allowance are included in net expenses from other real estate. Business Combinations The Company accounts for business combinations under the acquisition method of accounting in accordance with Accounting Standards Codification (“ASC”) 805, Business Combinations one 2. Goodwill and Intangible Assets Goodwill represents the excess of cost over the fair value of the net assets purchased in business combinations. Goodwill is required to be tested annually for impairment or whenever events occur that may fourth Intangible assets consist of core deposit premiums acquired in connection with business combinations and are based on the established value of acquired customer deposits. The core deposit premium is initially recognized based on a valuation performed as of the consummation date and is amortized over an estimated useful life of three ten Purchased Loans Purchased loans acquired in a business combination are recorded at estimated fair value on their purchase date. When the loans have evidence of credit deterioration since origination and it is probable at the date of acquisition that the Company will not collect all contractually required principal and interest payments, the difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is referred to as the non-accretable difference. The Company must estimate expected cash flows at each reporting date. Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent increases in expected cash flows result in a reversal of the provision for loan losses to the extent of prior provisions and an adjustment to accretable discount if no prior provisions have been made. This increase in accretable discount has a positive impact on interest income. In determining the initial fair value of purchased loans without evidence of credit deterioration at the date of acquisition management includes an adjustment to reflect an appropriate market rate of interest given the risk profile and grade assigned to each loan. This adjustment is accreted into earnings as a yield adjustment, using the effective yield method, over the remaining life of each loan. Income Taxes Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. In the event that the future tax consequences of differences between the financial reporting bases and the tax bases of the assets and liabilities result in deferred tax assets, an evaluation of the probability of realizing the future benefits indicated by such asset is required. A valuation allowance is provided for the portion of the deferred tax asset when it is more likely than not that some portion or all of the deferred tax asset will not be realized. In assessing the realizability of the deferred tax assets, management considers the scheduled reversals of deferred tax liabilities, projected future taxable income, and tax planning strategies. The Company currently evaluates income tax positions judged to be uncertain. A loss contingency reserve is accrued if: (i) it is probable that the tax position will be challenged, (ii) it is probable that the future resolution of the challenge will confirm that a loss has been incurred, and (iii) the amount of such loss can be reasonably estimated. Derivative Financial Instruments and Hedging Activities In the normal course of business, the Company enters into derivative contracts to manage interest rate risk by modifying the characteristics of the related balance sheet instruments in order to reduce the adverse effect of changes in interest rates. All derivatives are recognized on the balance sheet at their value in accordance with ASC 815, Accounting for Derivative Instruments and Hedging Activities The Company formally documents all relationships between hedging instruments and hedged items, as well as its risk-management objective and strategy for undertaking various hedged transactions. This process includes linking all derivatives that are designated as fair value hedges to specific assets and liabilities on the balance sheet. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in fair values of hedged items. When it is determined that a derivative is not highly effective as a hedge, the Company discontinues hedge accounting prospectively, as discussed below. The Company discontinues hedge accounting prospectively when (1) (2) (3) (4) When hedge accounting is discontinued because it is determined that the derivative no longer qualifies as an effective fair value hedge, the derivative will continue to be carried on the balance sheet at its fair value, and the hedged asset or liability will no longer be adjusted for changes in fair value. When hedge accounting is discontinued because the hedged item no longer meets the definition of a firm commitment, the derivative will continue to be carried on the balance sheet at its fair value, and any asset or liability that was recorded pursuant to recognition of the firm commitment will be removed from the balance sheet and recognized as a gain or loss in current-period earnings. In all other situations in which hedge accounting is discontinued, the derivative will be carried at its fair value on the balance sheet, with changes in its fair value recognized in current-period earnings. Mortgage Banking Derivative Commitments In connection with its mortgage banking activities, the Company enters into loan commitments to fund residential mortgage loans at specified interest rates and within a specified period of time, generally up to 60 815, To hedge the exposure of changes in interest rates impacting the fair value of loans held for sale and related loan commitments, the Company typically enters into forward sales commitments with its secondary in order to mitigate interest rate risk, the Company enters into forward commitments to sell mortgage-backed securities and records the change in fair value of these derivatives through income.

Accumulated Other Comprehensive Income At December 31, 2016, 2015 2014, Net Earnings per Common Share Basic earnings per common share is computed by dividing net income by the weighted-average number of shares of common stock outstanding during the year. Diluted earnings per common share is computed by dividing net income by the effect of the issuance of potential common shares that are dilutive and by the sum of the weighted-average number of shares of common stock outstanding. Anti-dilutive potential common shares are excluded from the diluted earnings per share computation and totaled approximately 5,000 2014. 2016 2015, The reconciliation of the components of basic and diluted earnings per share is as follows: 2016 2015 2014 Net earnings available to common shareholders $ 17,853 9,605 5,403 Weighted average common shares outstanding 10,886,092 9,238,784 5,888,862 Dilutive effect of stock options 111,374 60,823 19,266 Dilutive effect of directors' deferred shares 20,471 10,398 - Dilutive effect of performance share awards 76,050 85,736 52,071 Diluted common shares 11,093,987 9,395,741 5,960,199 Basic earnings per common share $ 1.64 1.04 0.92 Diluted earnings per common share $ 1.61 1.02 0.91 Reclassifications Certain 2015 2014 2016.

The most significant of those determinations is related to the fair value of acquired loans. Acquired loans are initially recorded at their acquisition date fair values. The carryover of the allowance for loan losses is prohibited, as any credit losses in the loans are included in the determination of the fair value of the loans at the acquisition date. Fair values for acquired loans are based on a discounted cash flow methodology that involves assumptions including the remaining life of the acquired loans, estimated prepayments, estimated value of the underlying collateral, and net present value of cash flows expected to be collected. Acquired loans that have evidence of deterioration in credit quality since origination and for which it is probable, at acquisition, that the acquirer will be unable to collect all contractually required payments are specifically identified and analyzed. The excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable discount and is recognized into interest income over the remaining life of the loan. The difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is referred to as the non-accretable discount. The non-accretable discount represents estimated future credit losses expected to be incurred over the life of the loan.

A loan is considered impaired when, based on current events and circumstances, it is probable that all amounts due according to the contractual terms of the loan will not be collected. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, at the loan’s observable market price, or the fair value of the collateral (if the loan is collateral-dependent).

Regulatory Capital Requirements under Banking Regulations [Text Block]	(14) Regulatory Matters Banking regulations limit the amount of dividends that the Bank may The Company and the Bank are subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the financial statements. Under the regulatory framework for capital adequacy and prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities, and certain off-balance sheet items, as calculated under regulatory accounting practices. The capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. In July 2013, January 1, 2015, 1 1 one The rules are intended to provide an additional measure of a bank’s capital adequacy by assigning weighted levels of risk to asset categories.

Notes to Financial Statements
Fair Value Disclosures [Text Block]	(15) Fair Value Measurements and Disclosures The Company utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Securities available-for-sale and derivative financial instruments are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may Fair Value Hierarchy The Company groups assets and liabilities at fair value in three Level 1 Level 2 Valuation is based on quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Level 3 one The following is a description of valuation methodologies used for assets and liabilities recorded or disclosed at fair value. Cash and Cash Equivalents For disclosure purposes, for cash, due from banks, interest-bearing deposits, and federal funds sold, the carrying amount is a reasonable estimate of fair value. Investment Securities Securities available-for-sale are recorded at fair value on a recurring basis. Fair value measurements are based on quoted prices, if available. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques, such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions, and other factors, such as credit assumptions. Level 1 2 3 The fair value of securities held-to-maturity is estimated using the same measurement techniques as securities available-for-sale. Other Investments For disclosure purposes, the carrying amount of other investments approximates their fair value. Loans The Company does not record loans at fair value on a recurring basis. However, if a loan is considered impaired, then an allowance for loan losses is established. Loans for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement are considered impaired. Once a loan is identified as individually impaired, management measures impairment using one three December 31, 2016 2015, 2. 3. For disclosure purposes, the fair value of fixed-rate loans is estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings. For variable-rate loans, the carrying amount is a reasonable estimate of fair value. Mortgage Loans Held-for-Sale Prior to December 31, 2016, December 31, 2016, secondary Bank-Owned Life Insurance For disclosure purposes, the fair value of the cash surrender value of life insurance policies is equivalent to the carrying value. Other Real Estate Other real estate properties are adjusted to fair value upon transfer of the loans to other real estate. Subsequently, other real estate assets are carried at the net realizable value. This value is based on independent market prices, appraised values of the collateral, or management’s estimation of the value of the collateral. When the fair value of the collateral is based on an observable market price, the Company records the other real estate as nonrecurring Level 2. 3. Deposits For disclosure purposes, the fair value of demand deposits, NOW and money market accounts and savings accounts is the amount payable on demand at the reporting date. The fair value of fixed-rate maturity certificates of deposit is estimated by discounting the future cash flows using the rates currently offered for deposits of similar remaining maturities. Federal Home Loan Bank Advances For disclosure purposes, the fair value of the FHLB advances is based on the quoted value for similar remaining maturities provided by the FHLB. NATIONAL COMMERCE CORPORATION Notes to Consolidated Financial Statements, continued (amounts in tables in thousands, except share and per share data) Subordinated Debt For disclosure purposes, the fair value of our fixed-rate subordinated debt is estimated using a discounted cash flow model that utilizes current market interest rates on borrowings with a similar maturity. Derivative Financial Instruments Derivative financial instruments are recorded at fair value on a recurring basis . The valuation of the Company’s derivative financial instruments is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of the derivative. This analysis reflects the contractual terms of the derivative, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The fair value of the interest rate swaps is determined using the market standard methodology of netting the discounted future fixed cash receipts and the discounted expected variable cash payments. The variable cash payments are based on an expectation of future interest rates (forward curves derived from observable market interest rate curves). The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees.

Significant Accounting Policies

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2016
Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation The consolidated financial statements include the accounts of National Commerce Corporation (the “Company”) and its wholly-owned banking subsidiary, National Bank of Commerce (“NBC” or the “Bank”) and wholly-owned non-banking subsidiary, National Commerce Risk Management, Inc., a captive insurance company used to insure certain corporate risks. The consolidated financial statements also include the accounts of NBC’s majority-owned subsidiary, CBI Holding Company, LLC (“CBI”), which owns Corporate Billing, LLC (“Corporate Billing”). Corporate Billing is a transaction-based finance company headquartered in Decatur, Alabama that provides factoring, invoicing, collection and accounts receivable management services to transportation companies and automotive parts and service providers nationwide. The Bank provides a full range of commercial and consumer banking services throughout Alabama, central and northeast Florida and the Atlanta, Georgia metropolitan area. NBC is primarily regulated by the Office of the Comptroller of Currency (the “OCC”) and undergoes periodic examinations by the OCC. The Company is regulated by the Board of Governors of the Federal Reserve System (the “Federal Reserve”) and is also subject to periodic examinations by the Federal Reserve. The accounting principles followed by the Company and the method of applying these principles conform with accounting principles generally accepted in the United States of America (“GAAP”) and with general practices within the banking industry. In preparing financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts in the consolidated financial statements. Actual results could differ significantly from those estimates. Material estimates common to the banking industry that are particularly susceptible to significant change in the near term include, but are not limited 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 valuation allowances associated with the realization of deferred tax assets, which are based on future taxable income.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents Cash equivalents include amounts due from banks, interest-bearing deposits with the Federal Reserve Bank of Atlanta (“FRB”), Federal Home Loan Bank (“FHLB”) and correspondent banks, and federal funds sold. Generally, federal funds are sold for one December 31, 2016 2015, $8,139,000 $12,218,000,
Marketable Securities, Policy [Policy Text Block]	Investment Securities The Company classifies its securities in one three December 31, 2016, $26,329,000, $73,380,000. December 31, 2015, $27,458,000, $53,405,000. Available-for-sale securities are recorded at fair value. Held-to-maturity securities are recorded at cost, adjusted for the amortization or accretion of premiums or discounts. Unrealized holding gains and losses, net of the related tax effect, on securities available-for-sale are excluded from earnings and are reported as a separate component of shareholders’ equity until realized. Transfers of securities between categories are recorded at fair value at the date of transfer. Management evaluates investment securities for other-than-temporary impairment on a quarterly basis. A decline in the market value of any investment below cost that is deemed other-than-temporary is charged to earnings for the decline in value deemed to be credit-related, and a new cost basis in the security is established. The decline in value attributed to non-credit-related factors is recognized in other comprehensive income. Premiums and discounts are amortized or accreted over the life of the related securities as adjustments to the yield. Realized gains and losses are included in earnings and are derived using the specific identification method for determining the cost of securities sold.
Other Investments [Policy Text Block]	Other Investments Other investments include FRB stock, FHLB stock and other investments that do not have a readily determinable market value. These investments are carried at cost, which approximates fair value.
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	Loans and Allowance for Loan Losses Loans are stated at the principal amount outstanding, net of the allowance for loan losses. Interest on loans is calculated by using the simple interest method on daily balances of the principal amount outstanding. Nonrefundable loan fees and costs incurred for loans are deferred and recognized in income over the life of the loans. A loan is considered impaired when, based on current information and events, it is probable that all amounts due according to the contractual terms of the loan agreement will not be collected. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, at the loan’s observable market price, or at the fair value of the collateral of the loan if the loan is collateral-dependent. Accrual of interest is discontinued on a loan when management believes, after considering economic and business conditions and collection efforts, that the borrower's financial condition is such that collection of interest is doubtful. When a loan is placed on nonaccrual status, previously accrued and uncollected interest is charged to interest income on loans. Generally, payments on nonaccrual loans are applied to principal. When a borrower has demonstrated the capacity to service the debt for a reasonable period of time, management may The allowance for loan losses is established through a provision for loan losses charged to expense. Loans are charged against the allowance for loan losses when management believes that the collectibility of the principal is unlikely. The allowance represents an amount that, in management’s judgment, will be adequate to absorb probable losses on existing loans that may Management’s judgment in determining the adequacy of the allowance is based on evaluations of the collectibility of loans. These evaluations take into consideration such factors as changes in the nature and volume of the loan portfolio, current economic conditions that may Management believes that the allowance for loan losses is adequate. While management uses available information to recognize losses on loans, future additions to the allowance may may
Transfers and Servicing of Financial Assets, Policy [Policy Text Block]	Transfers of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) (2) (3)

The fair value of committed residential loans held-for-sale is determined by outstanding commitments from investors, and the fair value of uncommitted loans is based on the current delivery prices in the secondary
Property, Plant and Equipment, Policy [Policy Text Block]	Premises and Equipment Premises and equipment are stated at cost less accumulated depreciation. Major additions and improvements are charged to the property accounts, while replacements, maintenance, and repairs that do not improve or extend the life of the respective assets are expensed currently. When property is retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts, and the resulting gain or loss, if any, is recognized. Depreciation expense is computed using the straight-line method over the following estimated useful lives: Useful Life (in years) Building and improvements 10 - 40 Furniture and equipment 5 - 10 Leasehold improvements 18 Computer equipment 3 - 5
Other Real Estate Owned and Repossessed Assets [Policy Text Block]	Other Real Estate and Repossessed Assets Other real estate represents properties acquired through or in lieu of loan foreclosure and is initially recorded at fair value less estimated disposal costs.

Business Combinations Policy [Policy Text Block]	Business Combinations The Company accounts for business combinations under the acquisition method of accounting in accordance with Accounting Standards Codification (“ASC”) 805, Business Combinations one 2.
Goodwill and Intangible Assets, Policy [Policy Text Block]	Goodwill and Intangible Assets Goodwill represents the excess of cost over the fair value of the net assets purchased in business combinations. Goodwill is required to be tested annually for impairment or whenever events occur that may fourth Intangible assets consist of core deposit premiums acquired in connection with business combinations and are based on the established value of acquired customer deposits. The core deposit premium is initially recognized based on a valuation performed as of the consummation date and is amortized over an estimated useful life of three ten
Loans and Leases Receivable, Origination Fees, Discounts or Premiums, and Direct Costs to Acquire Loans Policy [Policy Text Block]	Purchased Loans Purchased loans acquired in a business combination are recorded at estimated fair value on their purchase date. When the loans have evidence of credit deterioration since origination and it is probable at the date of acquisition that the Company will not collect all contractually required principal and interest payments, the difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is referred to as the non-accretable difference. The Company must estimate expected cash flows at each reporting date. Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent increases in expected cash flows result in a reversal of the provision for loan losses to the extent of prior provisions and an adjustment to accretable discount if no prior provisions have been made. This increase in accretable discount has a positive impact on interest income. In determining the initial fair value of purchased loans without evidence of credit deterioration at the date of acquisition management includes and adjustment to reflect an appropriate market rate of interest given the risk profile and grade assigned to each loan. This adjustment is accreted into earnings as a yield adjustment, using the effective yield method, over the remaining life of each loan.
Income Tax, Policy [Policy Text Block]	Income Taxes Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. In the event that the future tax consequences of differences between the financial reporting bases and the tax bases of the assets and liabilities result in deferred tax assets, an evaluation of the probability of realizing the future benefits indicated by such asset is required. A valuation allowance is provided for the portion of the deferred tax asset when it is more likely than not that some portion or all of the deferred tax asset will not be realized. In assessing the realizability of the deferred tax assets, management considers the scheduled reversals of deferred tax liabilities, projected future taxable income, and tax planning strategies. The Company currently evaluates income tax positions judged to be uncertain. A loss contingency reserve is accrued if: (i) it is probable that the tax position will be challenged, (ii) it is probable that the future resolution of the challenge will confirm that a loss has been incurred, and (iii) the amount of such loss can be reasonably estimated.
Derivative Instruments and Hedging Activities [Policy Text Block]	Derivative Financial Instruments and Hedging Activities In the normal course of business, the Company enters into derivative contracts to manage interest rate risk by modifying the characteristics of the related balance sheet instruments in order to reduce the adverse effect of changes in interest rates. All derivatives are recognized on the balance sheet at their value in accordance with ASC 815, Accounting for Derivative Instruments and Hedging Activities The Company formally documents all relationships between hedging instruments and hedged items, as well as its risk-management objective and strategy for undertaking various hedged transactions. This process includes linking all derivatives that are designated as fair value hedges to specific assets and liabilities on the balance sheet. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in fair values of hedged items. When it is determined that a derivative is not highly effective as a hedge, the Company discontinues hedge accounting prospectively, as discussed below. The Company discontinues hedge accounting prospectively when (1) (2) (3) (4) When hedge accounting is discontinued because it is determined that the derivative no longer qualifies as an effective fair value hedge, the derivative will continue to be carried on the balance sheet at its fair value, and the hedged asset or liability will no longer be adjusted for changes in fair value. When hedge accounting is discontinued because the hedged item no longer meets the definition of a firm commitment, the derivative will continue to be carried on the balance sheet at its fair value, and any asset or liability that was recorded pursuant to recognition of the firm commitment will be removed from the balance sheet and recognized as a gain or loss in current-period earnings. In all other situations in which hedge accounting is discontinued, the derivative will be carried at its fair value on the balance sheet, with changes in its fair value recognized in current-period earnings.
Mortgage Banking Derivatives Policy [Policy Text Block]	Mortgage Banking Derivative Commitments In connection with its mortgage banking activities, the Company enters into loan commitments to fund residential mortgage loans at specified interest rates and within a specified period of time, generally up to 60 815, To hedge the exposure of changes in interest rates impacting the fair value of loans held for sale and related loan commitments, the Company typically enters into forward sales commitments with its secondary in order to mitigate interest rate risk, the Company enters into forward commitments to sell mortgage-backed securities and records the change in fair value of these derivatives through income. As of December 31, 2016 2015, $246,000 $184,000, $62,000, $86,000, $18,000 December 31, 2016, 2015 2014,
