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 is subject to 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 Cash and Cash Equivalents Cash equivalents include amounts due from banks, interest-bearing deposits with the Federal Reserve Bank of Atlanta (“FRB”), the Federal Home Loan Bank (“FHLB”) and correspondent banks, and federal funds sold. Generally, federal funds are sold for one December 31, 2018 2017, $37,840,000 $16,452,000, Investment Securities The Company classifies its securities in one three not December 31, 2018, $25,045,000, $187,516,000. December 31, 2017, $25,562,000, $84,834,000. No 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.

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.

For The Year Ended December 31, Performance Measure (pro forma, unaudited) 2018 2017 Net interest income $ 170,332 $ 155,369 Net earnings $ 45,663 $ 31,169 Diluted earnings per common share $ 2.21 $ 1.52 In many cases, determining the fair value of acquired assets and assumed liabilities requires the Company to estimate cash flows expected to result from those assets and liabilities and to discount those cash flows at appropriate rates of interest. 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.

For variable-rate loans, the carrying amount is a reasonable estimate of fair value. Mortgage Loans Held-for-Sale The fair value of committed mortgage 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 mortgage market. 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. 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. Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 3 December 31, 2018 2017, not 2 Commitments to Extend Credit and Standby Letters of Credit Because commitments to extend credit and standby letters of credit are generally short-term and made using variable rates, the carrying value and estimated fair value associated with these instruments are immaterial.

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 is subject to 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
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”), the Federal Home Loan Bank (“FHLB”) and correspondent banks, and federal funds sold.

December 31, 2017, $25,562,000, $84,834,000. No 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.

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 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

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 mortgage market. To mitigate the interest rate risk associated with mandatory delivery, the Company enters into forward commitments to sell mortgage-backed securities and records the change in fair value of these derivatives through income.
