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”), Federal Home Loan Bank (“FHLB”) and correspondent banks, and federal funds sold. Generally, federal funds are sold for one December 31, 2017 2016, $16,452,000 $8,139,000, Investment Securities The Company classifies its securities in one three selling them in the near term. Held-to-maturity securities are those securities that the Company has the ability and intent to hold until maturity. All securities not December 31, 2017, $25,562,000, $85,834,000. December 31, 2016, $26,329,000, $73,380,000. 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 sep arate 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, FH LB stock and other investments that do not 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 ’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 non-accrual status, previously accrued and uncollected interest is charged to interest income on loans. Generally, payments on non-accrual 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 es, periodically review the Company’s allowance for loan losses. Such agencies 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 (i.e., put presumptively beyond the reach of the transferor and its creditors, even in bankruptcy or other receivership), ( 2 3 not Mortgage Loans Held-for-Sale Prior to the year ended December 31, 2016, December 31, 2016, 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 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. 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 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 Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 805, Business Combinations no 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 not an annual test of impairment in the 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. Pursuant to ASC 310 30, Loans and Debt Securities Acquired with Deteriorated Credit Quality not no 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 not The Company currently evaluates income tax positions judged to be uncertain.

NBC continues to operate the former offices of Reunion as a division of NBC under the trade name “Reunion Bank of Florida.” In connection with the merger, we paid cash for cash elections and in lieu of fractional shares totaling $7,368,809 1,339,129 $43.2 $20.6 $4.1 The following unaudited supplemental pro forma information is presented to show estimated results assuming Private Bancshares and Patriot Bank were acquired as of January 1, 2016. not January 1, 2016 not 2017 2017. not 2017 For The Year Ended December 31, Performance Measure (pro forma, unaudited) 2017 2016 Net interest income $ 103,692 $ 88,447 Net earnings $ 21,258 $ 23,502 Diluted earnings per common share $ 1.45 $ 1.72 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. 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.

Regulatory Capital Requirements under Banking Regulations [Text Block]	( 14 Regulatory Matters Banking regulations limit the amount of dividends that the Bank may applicable regulatory authorities. These restrictions are based on the Bank’s level of regulatory classified assets, prior years’ net earnings, and ratio of equity capital to total assets. The Bank is currently allowed to pay dividends to the Company, subject to safety and soundness requirements and other limitations imposed by law and federal regulatory authorities. 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.

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 These levels are: Level 1 – Valuation is based on quoted prices for identical instruments traded in active markets. 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 Level 3 one not The f ollowing 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 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 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 one three not December 31, 2017 2016, 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 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 , to evaluate the likelihood of default by the Company or the counterparty. However, as of December 31, 2017 2016, 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.

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.

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 sep arate 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.

Interest on loans is calculated by using the simple interest method on daily balances of the principal amount outstanding.

When a loan is placed on non-accrual status, previously accrued and uncollected interest is charged to interest income on loans. Generally, payments on non-accrual 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.
