Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	1. BASIS OF PRESENTATION The accompanying unaudited consolidated financial statements include the accounts of QNB Corp. and its wholly-owned subsidiary, QNB Bank (the “Bank”). The consolidated entity is referred to herein as “QNB” or the “Company”. All significant intercompany accounts and transactions are eliminated in the consolidated financial statements. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in QNB's 2017 Annual Report incorporated in the Form 10-K. Operating results for the three-month period ended March 31, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018. The unaudited consolidated financial statements reflect all adjustments which, in the opinion of management, are necessary for a fair presentation of the results of operations for the period and are of a normal and recurring nature. Tabular information, other than share and per share data, is presented in thousands of dollars. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities at the dates of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from such estimates. QNB has evaluated events and transactions occurring subsequent to the balance sheet date of March 31, 2018, for items that should potentially be recognized or disclosed in these financial statements.

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
Recent Accounting Pronouncements	2. RECENT ACCOUNTING PRONOUNCEMENTS QNB adopted ASU 2016-01, Financial Instruments – Overall Recognition and Measurement of Financial Assets and Financial Liabilities, • Equity investments with readily determinable fair values are measured at fair value with changes in fair value recognized in net income. • Equity investments without readily determinable fair values must be measured at either fair value or at cost adjusted for changes in observable prices minus impairment. Changes in value under either of these methods would be recognized in net income. The Company chose to continue to measure equity investments without readily determinable fair value at cost adjusted for changes in observable prices minus impairment. The Company will reassess at each reporting period whether these equity investments without readily determinable fair values qualify to be measured in accordance with the practical expedient to estimate fair value. The Company can subsequently elect to measure these equity investments, if they qualify, at the estimated fair value under the practical expedient; but the election would be irrevocable. Any gains or losses resulting from changes in the fair value would be recognized in net income. • Entities must assess whether a valuation allowance is required for deferred tax assets related to available-for-sale debt securities. QNB used the modified retrospective method for transition in which the cumulative effect will be recognized at the date of adoption with no restatement of comparative periods presented. QNB reclassed a net loss of $254,000 from accumulated other comprehensive loss to retained earnings on January 1, 2018. Based on an evaluation of our deferred tax asset and considering the effect of the new guidance, management believes that deferred tax assets related to AFS debt securities are realizable and no valuation allowance would be required. Management believes the potential effect of using exit versus entry price is most relevant for fair value disclosures of loans, which considers the impact of credit risk on fair value. On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (2017 Tax Reform Act) was enacted into law. The 2017 Tax Reform Act made significant changes to U.S. corporate income tax laws including a decrease in the corporate income tax rate from 35% to 21% effective January 1, 2018. The Company recorded less tax expense for the first quarter of 2018 than in the comparable quarter of 2017, with effective tax rates of 16.0% in 2018 compared to 28.2% in 2017, primarily a result of the 2017 Tax Reform Act. QNB adopted ASU 2018-02, Income Statement—Reporting Comprehensive Income (Topic 202) Income Statement—Reporting Comprehensive Income QNB adopted Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (Topic 606) (ASC 606), effective January 1, 2018. Under ASU 2014-09, revenue is recognized when a customer obtains control of promised services in an amount that reflects the consideration the entity expects to receive in exchange for those services. In addition, the standard requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. QNB applied the five-step method outlined in ASU 2014-09 to all revenue streams scoped-in by the ASU and elected the modified retrospective implementation method. Substantially all of QNB’s interest income and non-interest income were not impacted by the adoption of this ASU because either the revenue from those contracts with customers is covered by other guidance in U.S. GAAP or the revenue recognition outcomes were similar to our current revenue recognition practices. We reviewed non-interest sources of income and related contracts to document the impact of the new standard on our service offerings that are in the scope of the ASU including: service charges on deposits; ATM and debit card income; retail brokerage and advisory fees; merchant income; credit card income; sale of checks to depositors; miscellaneous fees; and sale of OREOs. Upon our analysis we concluded that the adoption of ASC 606 did not change the timing and pattern of revenue recognition related to scoped in non-interest income source and only required additional disclosures. In addition, we reviewed, and where necessary, enhanced our business processes, systems and controls to support recognition and disclosures under the new standard. The implementation of the guidance had no material impact on the measurement or recognition of revenue of prior periods, however, additional disclosures have been added in accordance with the ASU. The Company generally fully satisfies its performance obligations on its contracts with customers as services are rendered and the transaction prices are typically fixed; charged either on a periodic basis or based on activity. Because performance obligations are satisfied as services are rendered and the transaction prices are fixed, there is little judgment involved in applying Topic 606 that significantly affects the determination of the amount and timing of revenue from contracts with customers. The main types of revenue contracts included in non-interest income within the consolidated statements of operations are as follows: • Fees for services to customer—fees include service charges on deposits which are included as liabilities in the consolidated statement of financial position and consist of transaction-based fees, stop payment fees, Automated Clearing House (ACH) fees, account maintenance fees, and overdraft services fees for various retail and business checking customers. These fees are charged as earned on the day of the transaction or within the month of the service, with the exception of Enhanced Account Analysis Fees, which are calculated on the previous month’s activity and assessed on the following month. The Enhanced Account Analysis Fees are currently being accrued; the revenue is currently being recorded in the month it is earned. Service charges on deposits are withdrawn directly from the customer’s account balance. • ATM and debit card – fees are recognized at the time the transaction is executed as that is the point in time the Company fulfills the customer’s request. • Retail brokerage and advisory—fee income and related expenses are accrued monthly to properly record the revenues in the month they are earned. Advisory fees are collected in advance on a quarterly basis. These advisory fees and recorded in the first month of the quarter for which the service is being performed. Fees that are transaction based are recognized at the point in time that the transaction is executed (i.e. trade date). • Merchant – QNB earns interchange fees from credit/debit cardholder transactions conducted through VISA/MasterCard payment network. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized monthly, concurrently with the transaction processing services provided to the cardholder within the month. • Other—includes credit card fees, sales of checks to depositors, miscellaneous fees and gain/losses on sale of OREO. Credit card fees are recognized monthly, concurrently with the transaction processing services provided to the cardholder within the month. • Sales of checks to depositors are commissions earned from a third-party who provides checks to QNB’s customers. There is a pre-paid incentive with the third party which is recognized over the term of the contact. Other commissions on the sales of checks are recorded weekly. • Miscellaneous fees, such as wire, cashier check and garnishment fees, are charged as earned on the day of the transaction • Gain (loss) on sales of OREO – QNB records a gain or loss from the sale of OREO when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. When the QNB finances the sale of OREO to the buyer, QNB assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the OREO asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determine the gain or loss on the sale, QNB adjusts the transaction prices and related gain (loss) on sale if a significant financing component is present. On February 25, 2016, the FASB issued ASU 2016-02, Leases (Topic 842) On June 16, 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326) To that end, the new guidance: • Eliminates the probable initial recognition threshold in current U.S. GAAP and, instead, reflects an organization’s current estimate of all expected credit losses over the contractual term of its financial assets • Broadens the information an entity can consider when measuring credit losses to include forward-looking information • Increases usefulness of the financial statements by requiring timely inclusion of forecasted information in forming expectations of credit losses • Increases comparability of purchased financial assets with credit deterioration (PCD assets) with other purchased assets that do not have credit deterioration as well as originated assets because credit losses that are expected will be recorded through an allowance for credit losses for all assets • Increases users’ understanding of underwriting standards and credit quality trends by requiring additional information about credit quality indicators by year of origination (vintage) • For available-for-sale debt securities, aligns the income statement recognition of credit losses with the reporting period in which changes occur by recording credit losses (and subsequent changes in credit losses) through an allowance rather than a write down The new guidance affects organizations that hold financial assets and net investments in leases that are not accounted for at fair value with changes in fair value reported in net income. The new guidance affects loans, debt securities, trade receivables, net investments in leases, off-balance-sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. For public business entities that are U.S. Securities and Exchange Commission (SEC) filers, the new guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early application will be permitted for all organizations for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. QNB is evaluating the impact of this new standard on its consolidated financial statements. On March 30, 2017, the FASB issued ASU 2017-08, Premium Amortization on Purchased Callable Debt Securities

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Stock-Based Compensation and Shareholders Equity	3. STOCK-BASED COMPENSATION AND SHAREHOLDERS’ EQUITY QNB sponsors stock-based compensation plans, administered by a Board committee, under which both qualified and non-qualified stock options may be granted periodically to certain employees. Compensation cost has been measured using the fair value of an award on the grant date and is recognized over the service period, which is usually the vesting period. Stock-based compensation expense was $22,000 and $18,000 for the three months ended March 31, 2018 and 2017, respectively. As of March 31, 2018, there was approximately $185,000 of unrecognized compensation cost related to unvested share-based compensation award grants that is expected to be recognized over the next 35 months. Options are granted to certain employees at prices equal to the market value of the stock on the date the options are granted. The 2005 Plan authorized the issuance of 200,000 shares. The time period during which any option is exercisable under the Plan is determined by the Committee but shall not commence before the expiration of six months after the date of grant or continue beyond the expiration of five years after the date the option is awarded. The granted options vest after a three-year period. As of March 31, 2018, there were 184,200 options granted, 65,350 options forfeited, 91,575 options exercised, and 27,275 options outstanding under this Plan. The 2005 Plan expired on March 15, 2015. The 2015 Plan authorizes the issuance of 300,000 shares. The terms of the 2015 Plan are identical to the 2005 Plan. There were 73,500 options granted and outstanding under this Plan as of March 31, 2018. There were no options forfeited and no options exercised as of March 31, 2018. The 2015 Plan expires on February 24, 2025. The fair value of each option is amortized into compensation expense on a straight-line basis between the grant date for the option and each vesting date. QNB estimated the fair value of stock options on the date of the grant using the Black-Scholes option pricing model. The model requires the use of numerous assumptions, many of which are highly subjective in nature. The following assumptions were used in the option pricing model in determining the fair value of options granted during the period: Three months ended March 31, 2018 2017 Risk free interest rate 2.15 % 1.48 % Dividend yield 1.24 % 3.19 % Volatility 18.12 % 17.89 % Expected life (years) 4.20 4.20 The risk-free interest rate was selected based upon yields of U.S. Treasury issues with a term approximating the expected life of the option being valued. Historical information was the primary basis for the selection of the expected dividend yield, expected volatility and expected lives of the options. The fair market value of options granted in the first three months of 2018 and 2017 was $5.29 and $3.88, respectively.

Investment Securities	6. INVESTMENT SECURITIES QNB engaged in trading activities for its own account. Municipal securities that were held principally for resale in the near term were recorded in the trading account at fair value with changes in fair value recorded in non-interest income. During the second quarter of 2017, QNB Bank redeemed the trading securities portfolio, as lack of volatility and the interest rate environment resulting in declining performance of the portfolio. The net realized and unrealized gains were $17,000 for the first quarter of 2017. Interest and dividends were included in interest income. The amortized cost and estimated fair values of investment debt securities available-for-sale and equity securities at March 31, 2018 and December 31, 2017 were as follows: Gross Gross unrealized unrealized Fair holding holding Amortized March 31, 2018 value gains losses cost U.S. Government agency $ 69,772 $ — $ (2,702 ) $ 72,474 State and municipal 71,333 269 (629 ) 71,693 U.S. Government agencies and sponsored enterprises (GSEs): Mortgage-backed 133,567 132 (4,715 ) 138,150 Collateralized mortgage obligations (CMOs) 74,783 16 (3,180 ) 77,947 Pooled trust preferred 115 — (8 ) 123 Corporate debt 7,949 5 (104 ) 8,048 Equity 9,527 169 (737 ) 10,095 Total investment debt securities available-for-sale and equity securities $ 367,046 $ 591 $ (12,075 ) $ 378,530 Gross Gross unrealized unrealized Fair holding holding Amortized December 31, 2017 value gains losses cost U.S. Government agency $ 70,524 $ — $ (1,948 ) $ 72,472 State and municipal 76,804 717 (113 ) 76,200 U.S. Government agencies and sponsored enterprises (GSEs): Mortgage-backed 142,703 195 (2,401 ) 144,909 Collateralized mortgage obligations (CMOs) 76,302 29 (2,292 ) 78,565 Pooled trust preferred 215 — (26 ) 241 Corporate debt 8,022 6 (37 ) 8,053 Equity 4,975 28 (349 ) 5,296 Total investment debt securities available-for-sale and equity securities $ 379,545 $ 975 $ (7,166 ) $ 385,736 The amortized cost and estimated fair value of debt securities available-for-sale by contractual maturity at March 31, 2018 are shown in the following table. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Securities are assigned to categories based on contractual maturity except for mortgage-backed securities and CMOs which are based on the estimated average life of these securities and municipal securities that have been pre-refunded.

Proceeds from sales of investment equity securities were approximately $712,000 and $4,510,000 for the three months ended March 31, 2018 and 2017, respectively. At March 31, 2018 and December 31, 2017, investment debt securities available-for-sale totaling approximately $193,454,000 and $202,887,000, respectively, were pledged as collateral for repurchase agreements and deposits of public funds. The following table presents information related to the Company’s gains and losses on the sales of equity and debt securities, and losses recognized for the other-than-temporary impairment (“OTTI”) of these investments. Gains and losses on available-for-sale securities are computed on the specific identification method and included in non-interest income. Gross realized losses on equity and debt securities are net of other-than-temporary impairment charges: Three months ended March 31, 2018 Three months ended March 31, 2017 Other-than- Other-than- Gross Gross temporary Gross Gross Gross Gross temporary realized realized impairment unrealized unrealized realized realized impairment gains losses losses gains losses Net losses gains losses losses Net gains Equity securities $ 86 $ — $ — $ 156 $ (402 ) $ (160 ) $ 725 $ — $ — $ 725 Debt securities available-for-sale 21 (22 ) — — — (1 ) 78 (54 ) — 24 Total $ 107 $ (22 ) $ — $ 156 $ (402 ) $ (161 ) $ 803 $ (54 ) $ — $ 749 The taxes applicable to the net realized (losses)/gains for the three-month periods ended March 31, 2018 and 2017 were a credit of $25,000 and an expense of $254,000, respectively. QNB recognizes OTTI for debt securities classified as available-for-sale in accordance with FASB ASC 320, Investments – Debt and Equity Securities The following table presents a roll forward of the credit loss component recognized in earnings. The credit loss component of the amortized cost represents the difference between the present value of expected future cash flows and the amortized cost basis of the security prior to considering credit losses. The beginning balance represents the credit loss component for debt securities for which OTTI occurred prior to the beginning of the year. Credit-impaired debt securities must be presented in two components based upon whether the current period is the first time the debt security was credit-impaired (initial credit impairment) or is not the first time the debt security was credit-impaired (subsequent credit impairments). No credit impairments were recognized on debt securities during first quarter of 2018 or 2017. The table presents a summary of the cumulative credit-related other-than-temporary impairment charges recognized as components of earnings for debt securities still held by QNB: Three months ended March 31, 2018 2017 Balance, beginning of period $ 1 $ 1,153 Reductions: sale, collaterized debt obligation — — Additions: Initial credit impairments — — Subsequent credit impairments — — Balance, end of period $ 1 $ 1,153 The following table indicates the length of time individual securities have been in a continuous unrealized loss position at March 31, 2018 and December 31, 2017: Less than 12 months 12 months or longer Total No. of Fair Unrealized Fair Unrealized Fair Unrealized March 31, 2018 securities value losses value losses value losses U.S. Government agency 53 $ 10,723 $ (262 ) $ 59,049 $ (2,440 ) $ 69,772 $ (2,702 ) State and municipal 103 37,796 (509 ) 4,374 (120 ) 42,170 (629 ) U.S. Government agencies and sponsored enterprises (GSEs): Mortgage-backed 104 61,600 (1,841 ) 68,378 (2,874 ) 129,978 (4,715 ) Collateralized mortgage obligations (CMOs) 73 23,284 (640 ) 49,933 (2,540 ) 73,217 (3,180 ) Pooled trust preferred 1 — — 115 (8 ) 115 (8 ) Corporate debt 6 4,973 (71 ) 971 (33 ) 5,944 (104 ) Equity 22 5,359 (551 ) 642 (186 ) 6,001 (737 ) Total 362 $ 143,735 $ (3,874 ) $ 183,462 $ (8,201 ) $ 327,197 $ (12,075 ) Less than 12 months 12 months or longer Total No. of Fair Unrealized Fair Unrealized Fair Unrealized December 31, 2017 securities value losses value losses value losses U.S. Government agency 53 $ 10,828 $ (155 ) $ 59,696 $ (1,793 ) $ 70,524 $ (1,948 ) State and municipal 37 10,577 (49 ) 4,446 (64 ) 15,023 (113 ) U.S. Government agencies and sponsored enterprises (GSEs): Mortgage-backed 99 61,069 (705 ) 72,318 (1,696 ) 133,387 (2,401 ) Collateralized mortgage obligations (CMOs) 70 21,660 (349 ) 52,833 (1,943 ) 74,493 (2,292 ) Pooled trust preferred 1 — — 215 (26 ) 215 (26 ) Corporate debt 4 3,018 (20 ) 988 (17 ) 4,006 (37 ) Equity 11 2,727 (277 ) 275 (72 ) 3,002 (349 ) Total 275 $ 109,879 $ (1,555 ) $ 190,771 $ (5,611 ) $ 300,650 $ (7,166 ) Management evaluates debt securities, which are comprised of U.S. Government agencies, state and municipalities, mortgage-backed securities, CMOs and corporate debt securities, for other-than-temporary impairment and considers the current economic conditions, the length of time and the extent to which the fair value has been less than cost, interest rates and the bond rating of each security. The unrealized losses at March 31, 2018 in U.S. Government agency securities, state and municipal securities, mortgage-backed securities, CMOs and corporate debt securities are primarily the result of interest rate fluctuations. If held to maturity, these bonds will mature at par, and QNB will not realize a loss. The Company has the intent to hold the securities and does not believe it will be required to sell the securities before recovery occurs. The Company’s investment in marketable equity securities primarily consists of investments in large cap stock companies. These equity securities are analyzed for impairment on an ongoing basis. Management believes these equity securities will recover in the foreseeable future. QNB evaluated the near-term prospects of the issuers in relation to the severity and duration of the impairment. Based on that evaluation and the Company’s ability and intent to hold those securities for a reasonable period of time sufficient for a forecasted recovery of fair value, the Company does not consider these equity securities to be other-than-temporarily impaired. QNB holds one pooled trust preferred security as of March 31, 2018. This security has a total amortized cost of approximately $123,000 and a fair value of $115,000. The pooled trust preferred security is available-for-sale securities and is carried at fair value. The following table provides additional information related to the pooled trust preferred security (PreTSL) as of March 31, 2018: Deal Class Book value Fair value Unrealized gains (losses) Realized OTTI credit loss (YTD 2018) Total recognized OTTI credit loss Moody's /Fitch ratings Current number of performing banks Current number of performing insurance companies Actual deferrals and defaults as a % of total collateral Total performing collateral as a % of outstanding bonds PreTSL IV Mezzanine * $ 123 $ 115 $ (8 ) $ — $ (1 ) Ba1/BB 4 — 0.00 % 184.6 % Mezzanine* - only class of bonds still outstanding (represents the senior-most obligation of the trust) In June 2017, QNB Bank sold five non-performing pooled trust preferred securities, with $2,235,000 carrying value, recording a loss on sale of $15,000, included in non-interest income in the quarter ended June 30, 2017 consolidated statement of income. Several years ago, QNB had recorded $1,152,000 in OTTI for four of these five bonds, and subsequently applied any cashflow received to the balance of these non-performing, nonaccrual assets. Improvement in market prices for these securities during the second quarter 2017 reduced realized losses, and the reduction of approximately $19,000,000 in risk-based assets required for the bonds drove the decision to redeem these debt securities. On a quarterly basis we evaluate our debt securities for OTTI, which involves the use of a third-party valuation firm to assist management with the valuation. When evaluating these investments, a credit-related portion and a non-credit related portion of impairment are determined. The credit-related portion is recognized in earnings and represents the expected shortfall in future cash flows. The non-credit related portion is recognized in other comprehensive income and represents the difference between the book value and the fair value of the security less any current quarter credit related impairment. For the first quarter of March 31, 2018 and 2017, no other-than-temporary impairment charges representing credit impairment were recognized on our pooled trust preferred collateralized debt obligations. A discounted cash flow analysis provides the best estimate of credit related OTTI for these securities. Additional information related to this analysis follows. PreTSL IV is rated lower than AA and measured for OTTI within the scope of ASC 325 (formerly known as EITF 99-20), Recognition of Interest Income and Impairment on Purchased Beneficial Interests and Beneficial Interests That Continue to be Held by a Transferor in Securitized Financial Assets, and Amendments to the Impairment Guidance of EITF Issue No. 99-20 (formerly known as EITF 99-20-1). In addition to discounted cash-flows, QNB considers trends in the financial performance ratios of the bond’s underlying issuers, as well as the bond’s structure (QNB holds the senior-most obligation of the trust for PreTSL IV), determining there is little likelihood of default. In determining whether a credit loss exists, QNB uses its best estimate of the present value of cash flows expected to be collected from the debt security and discounts them at the effective yield implicit in the security at the date of acquisition or the prospective yield for those securities with prior OTTI charges. Lack of liquidity in the market for trust preferred collateralized debt obligations contributed to the temporary impairment of this security. Although classified as available-for-sale, the Company has the intent to hold PreTSL IV and does not believe it will be required to sell it before recovery occurs. QNB could be subject to additional write-downs in the future if additional deferrals and defaults occur.

Restricted Investment in Stock	7. RESTRICTED INVESTMENT IN STOCK Restricted investment in stock includes Federal Home Loan Bank of Pittsburgh (FHLB) with a carrying cost of $1,454,000, Atlantic Community Bankers Bank (ACBB) stock with a carrying cost of $12,000 and VISA Class B stock with a carrying cost of $0 at March 31, 2018. FHLB and ACBB stock was issued to the Bank as a requirement to facilitate the Bank’s participation in borrowing and other banking services. The Bank’s investment in FHLB stock may fluctuate, as it is based on the member banks’ use of FHLB’s services. The Bank owns 6,502 shares of Visa Class B stock, which was necessary to participate in Visa services in support of the Bank’s credit card, debit card, and related payment programs (permissible activities under banking regulations) as a member institution. Following the resolution of Visa’s covered litigation, shares of Visa’s Class B stock will be converted to Visa Class A shares using a conversion factor (1.6483 as of March 31, 2018), which is periodically adjusted to reflect VISA’s ongoing litigation costs. There is a very limited market for this stock, as only current owners of Class B shares are permitted to transact in Class B. Due to the lack of orderly trades and public information of such trades, Visa Class B does not have a readily determinable fair value. These restricted investments are carried at cost and evaluated for OTTI periodically. As of March 31, 2018, there was no OTTI associated with these shares.

Receivables [Abstract]
Loans & Allowance for Loan Losses	8. LOANS & ALLOWANCE FOR LOAN LOSSES Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are stated at the principal amount outstanding, net of deferred loan fees and costs. Interest income is accrued on the principal amount outstanding. Loan origination and commitment fees and related direct costs are deferred and amortized to income over the term of the respective loan and loan commitment period as a yield adjustment. Loans held-for-sale consists of residential mortgage loans that are carried at the lower of aggregate cost or fair value. Net unrealized losses, if any, are recognized through a valuation allowance charged to income. Gains and losses on residential mortgages held-for-sale are included in non-interest income. QNB maintains an allowance for loan losses, which is intended to absorb probable known and inherent losses in the outstanding loan portfolio. The allowance is reduced by actual credit losses and is increased by the provision for loan losses and recoveries of previous losses. The provisions for loan losses are charged to earnings to bring the total allowance for loan losses to a level considered necessary by management. The allowance for loan losses is based on management’s continuing review and evaluation of the loan portfolio. The level of the allowance is determined by assigning specific reserves to individually identified problem credits and general reserves to all other loans. For such loans that are also classified as impaired, an allowance is established when the discounted cash flows (or collateral value) of the impaired loan is lower than the carrying value of that loan. The portion of the allowance that is allocated to internally criticized and non-accrual loans is determined by estimating the inherent loss on each credit after giving consideration to the value of underlying collateral. The general component covers pools of loans by loan class including commercial loans not considered impaired, as well as smaller balance homogeneous loans, such as residential real estate, home equity and other consumer loans. These pools of loans are evaluated for loss exposure based upon historical loss rates. These loss rates are based on a three year history of charge-offs and are more heavily weighted for recent experience for each of these categories of loans, adjusted for qualitative factors. These qualitative risk factors include: 1. Lending policies and procedures, including underwriting standards and collection, charge-off and recovery practices. 2. Effect of external factors, such as legal and regulatory requirements. 3. National, regional, and local economic and business conditions as well as the condition of various market segments, including the value of underlying collateral for collateral dependent loans. 4. Nature and volume of the portfolio including growth. 5. Experience, ability, and depth of lending management and staff. 6. Volume and severity of past due, classified and nonaccrual loans. 7. Quality of the Company’s loan review system, and the degree of oversight by the Company’s Board of Directors. 8. Existence and effect of any concentrations of credit and changes in the level of such concentrations. Each factor is assigned a value to reflect improving, stable or declining conditions based on management’s best judgment using relevant information available at the time of the evaluation. An unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio. Management emphasizes loan quality and close monitoring of potential problem credits. Credit risk identification and review processes are utilized in order to assess and monitor the degree of risk in the loan portfolio. QNB’s lending and credit administration staff are charged with reviewing the loan portfolio and identifying changes in the economy or in a borrower’s circumstances which may affect the ability to repay debt or the value of pledged collateral. A loan classification and review system exists that identifies those loans with a higher than normal risk of uncollectibility. Each commercial loan is assigned a grade based upon an assessment of the borrower’s financial capacity to service the debt and the presence and value of collateral for the loan. An independent firm reviews risk assessment and evaluates the adequacy of the allowance for loan losses. Management meets monthly to review the credit quality of the loan portfolio and quarterly to review the allowance for loan losses. In addition, various regulatory agencies, as an integral part of their examination process, periodically review QNB’s allowance for loan losses. Such agencies may require QNB to recognize additions to the allowance based on their judgments using information available to them at the time of their examination. Management believes that it uses the best information available to make determinations about the adequacy of the allowance and that it has established its existing allowance for loan losses in accordance with GAAP. If circumstances differ substantially from the assumptions used in making determinations, future adjustments to the allowance for loan losses may be necessary and results of operations could be affected. Because future events affecting borrowers and collateral cannot be predicted with certainty, there can be no assurance that increases to the allowance will not be necessary should the quality of any loans deteriorate as a result of the factors discussed above. Major classes of loans are as follows: March 31 December 31, 2018 2017 Commercial: Commercial and industrial $ 157,376 $ 147,190 Construction 50,664 51,157 Secured by commercial real estate 289,785 286,867 Secured by residential real estate 73,752 71,703 State and political subdivisions 40,281 38,087 Retail: 1-4 family residential mortgages 59,295 55,818 Home equity loans and lines 72,045 75,576 Consumer 6,782 6,680 Total loans 749,980 733,078 Net unearned costs 207 205 Loans receivable $ 750,187 $ 733,283 Loans secured by commercial real estate include all loans collateralized at least in part by commercial real estate. These loans may not be for the expressed purpose of conducting commercial real estate transactions. Overdrafts are reclassified as loans and are included in consumer loans above and total loans on the balance sheet. At March 31, 2018 and December 31, 2017, overdrafts were approximately $146,000 and $126,000, respectively. QNB generally lends in its trade area which is comprised of Quakertown and the surrounding communities. To a large extent, QNB makes loans collateralized at least in part by real estate. Its lending activities could be affected by changes in the general economy, the regional economy, or real estate values. Other than disclosed in the table above, at March 31, 2018, there were no concentrations of loans exceeding 10% of total loans. The Company engages in a variety of lending activities, including commercial, residential real estate and consumer transactions. The Company focuses its lending activities on individuals, professionals and small to medium sized businesses. Risks associated with lending activities include economic conditions and changes in interest rates, which can adversely impact both the ability of borrowers to repay their loans and the value of the associated collateral. Commercial and industrial loans, commercial real estate loans, construction loans and residential real estate loans with a business purpose are generally perceived as having more risk of default than residential real estate loans with a personal purpose and consumer loans. These types of loans involve larger loan balances to a single borrower or groups of related borrowers and are more susceptible to a risk of loss during a downturn in the business cycle. These loans may involve greater risk because the availability of funds to repay these loans depends on the successful operation of the borrower’s business. The assets financed are used within the business for its ongoing operation. Repayment of these kinds of loans generally comes from the cash flow of the business or the ongoing conversions of assets, such as accounts receivable and inventory, to cash. Typical collateral for commercial and industrial loans includes the borrower’s accounts receivable, inventory and machinery and equipment. Commercial real estate and residential real estate loans secured for a business purpose are originated primarily within the eastern Pennsylvania market area at conservative loan-to-value ratios and often backed by the individual guarantees of the borrowers or owners. Repayment of this kind of loan is dependent upon either the ongoing cash flow of the borrowing entity or the resale of or lease of the subject property. Commercial real estate loans may be affected to a greater extent than residential loans by adverse conditions in real estate markets or the economy because commercial real estate borrowers’ ability to repay their loans depends on successful development of their properties, as well as the factors affecting residential real estate borrowers. Loans to state and political subdivisions are tax-exempt or taxable loans to municipalities, school districts and housing and industrial development authorities. These loans can be general obligations of the municipality or school district repaid through their taxing authority, revenue obligations repaid through the income generated by the operations of the authority, such as a water or sewer authority, or loans issued to a housing and industrial development agency, for which a private corporation is responsible for payments on the loans. The Company originates fixed-rate and adjustable-rate real estate-residential mortgage loans for personal purposes that are secured by first liens on the underlying 1-4 family residential properties. Credit risk exposure in this area of lending is minimized by the evaluation of the credit worthiness of the borrower, including debt-to-income ratios, credit scores and adherence to underwriting policies that emphasize conservative loan-to-value ratios of generally no more than 80%. Residential mortgage loans granted in excess of the 80% loan-to-value ratio criterion are generally insured by private mortgage insurance. The real estate-home equity portfolio consists of fixed-rate home equity loans and variable-rate home equity lines of credit. Risks associated with loans secured by residential properties are generally lower than commercial loans and include general economic risks, such as the strength of the job market, employment stability and the strength of the housing market. Since most loans are secured by a primary or secondary residence, the borrower’s continued employment is the greatest risk to repayment. The Company offers a variety of loans to individuals for personal and household purposes. Consumer loans are generally considered to have greater risk than first or second mortgages on real estate because they may be unsecured, or, if they are secured, the value of the collateral may be difficult to assess and is more likely to decrease in value than real estate. Credit risk in this portfolio is controlled by conservative underwriting standards that consider debt-to-income levels and the creditworthiness of the borrower and, if secured, collateral values. The Company employs a ten-grade risk rating system related to the credit quality of commercial loans, loans to state and political subdivisions and indirect lease financing of which the first four categories are pass categories (credits not adversely rated). The following is a description of the internal risk ratings and the likelihood of loss related to each risk rating. 1 - Excellent - no apparent risk 2 - Good - minimal risk 3 - Acceptable - lower risk 4 - Acceptable - average risk 5 - Acceptable – high risk 6 - Pass watch 7 - Special Mention - potential weaknesses 8 - Substandard - well defined weaknesses 9 - Doubtful - full collection unlikely 10 - Loss - considered uncollectible The Company maintains a loan review system, which allows for a periodic review of our loan portfolio and the early identification of potential problem loans. Each loan officer assigns a rating to all loans in the portfolio at the time the loan is originated. Loans with risk ratings of one through five are reviewed annually based on the borrower’s fiscal year. Loans with risk ratings of six are reviewed every six to twelve months based on the dollar amount of the relationship with the borrower. Loans with risk ratings of seven through ten are reviewed at least quarterly, and as often as monthly, at management’s discretion. The Company also utilizes an outside loan review firm to review the portfolio on a semi-annual basis to provide the Board of Directors and senior management an independent review of the Bank’s loan portfolio on an ongoing basis. These reviews are designed to recognize deteriorating credits in their earliest stages in an effort to reduce and control risk in the lending function as well as identifying potential shifts in the quality of the loan portfolio. The examinations by the outside loan review firm include the review of lending activities with respect to underwriting and processing new loans, monitoring the risk of existing loans and to provide timely follow-up and corrective action for loans showing signs of deterioration in quality. In addition, the outside firm reviews the methodology for the allowance for loan losses to determine compliance to policy and regulatory guidance. The following tables present the classes of the loan portfolio summarized by the aggregate pass rating and the classified ratings of special mention, substandard and doubtful within the Company’s internal risk rating system as of March 31, 2018 and December 31, 2017: March 31, 2018 Pass Special mention Substandard Doubtful Total Commercial: Commercial and industrial $ 149,196 $ 878 $ 7,302 $ — $ 157,376 Construction 50,664 — — — 50,664 Secured by commercial real estate 271,091 10,499 8,195 — 289,785 Secured by residential real estate 71,612 221 1,919 — 73,752 State and political subdivisions 40,281 — — — 40,281 Total $ 582,844 $ 11,598 $ 17,416 $ — $ 611,858 December 31, 2017 Pass Special mention Substandard Doubtful Total Commercial: Commercial and industrial $ 139,820 $ 863 $ 6,507 $ — $ 147,190 Construction 51,156 — 1 — 51,157 Secured by commercial real estate 268,069 10,569 8,229 — 286,867 Secured by residential real estate 69,571 222 1,910 — 71,703 State and political subdivisions 38,087 — — — 38,087 Total $ 566,703 $ 11,654 $ 16,647 $ — $ 595,004 For retail loans, the Company evaluates credit quality based on the performance of the individual credits.

A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan by loan basis for commercial loans, loans to state and political subdivisions and indirect lease financing loans by using either the present value of expected future cash flows discounted at the loan’s effective interest rate or the fair value of the collateral if the loan is collateral dependent. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual consumer and residential mortgage loans for impairment disclosures, unless such loans are part of a larger relationship that is impaired or are classified as a troubled debt restructuring. An allowance for loan losses is established for an impaired loan if its carrying value exceeds its estimated fair value. The estimated fair values of the majority of the Company’s impaired loans are measured based on the estimated fair value of the loan’s collateral. For commercial loans secured by real estate, estimated fair values are determined primarily through third-party appraisals. When a real estate secured loan becomes impaired, a decision is made regarding whether an updated certified appraisal of the real estate is necessary. This decision is based on various considerations, including the age of the most recent appraisal, the loan-to-value ratio based on the original appraisal and the condition of the property. Appraised values are discounted to arrive at the estimated selling price of the collateral, which is considered to be the estimated fair value. The discounts also include estimated costs to sell the property. For commercial loans secured by non-real estate collateral, such as accounts receivable, inventory and equipment, estimated fair values are determined based on the borrower’s financial statements, inventory reports, accounts receivable agings or equipment appraisals or invoices. Indications of value from these sources are generally discounted based on the age of the financial information or the quality of the assets. From time to time, QNB may extend, restructure, or otherwise modify the terms of existing loans, on a case-by-case basis, to remain competitive and retain certain customers, as well as assist other customers that may be experiencing financial difficulties. A loan is considered to be a troubled debt restructuring (“TDR”) loan when the Company grants a concession to the borrower because of the borrower’s financial condition that it would not otherwise consider. Such concessions include the reduction of interest rates, forgiveness of principal or interest, or other modifications of interest rates to less than the current market rate for new obligations with similar risk. Loans classified as TDRs are considered non-performing and are also designated as impaired. The concessions made for TDRs involve lowering the monthly payments on loans through periods of interest only payments, a reduction in interest rate below a market rate or an extension of the term of the loan without a corresponding adjustment to the risk premium reflected in the interest rate, or a combination of these three methods. The restructurings rarely result in the forgiveness of principal or accrued interest. If the borrower has demonstrated performance under the previous terms and our underwriting process shows the borrower has the capacity to continue to perform under the restructured terms, the loan will continue to accrue interest. Non-accruing restructured loans may be returned to accrual status when there has been a sustained period of repayment performance (generally six consecutive months of payments) and both principal and interest are deemed collectible. TDR loans that are in compliance with their modified terms and that yield a market rate may be removed from the TDR status after a period of performance. Performing TDRs (not reported as non-accrual or past due 90 days or more and still accruing) totaled $1,274,000 and $1,321,000 as of March 31, 2018 and December 31, 2017, respectively. Non-performing TDRs totaled $2,530,000 and $2,994,000 as of March 31, 2018 and December 31, 2017, respectively. All TDRs are included in impaired loans. The following table illustrates the specific reserve for loan losses allocated to loans modified as TDRs. These specific reserves are included in the allowance for loan losses for loans individually evaluated for impairment.

The TDR concession involved extension of a maturity date and lower monthly payments. As of March 31, 2018 and December 31, 2017, QNB had no commitments to lend additional funds to customers with loans whose terms have been modified in troubled debt restructurings. There were net charge-offs of $0 and $3,000 during the three months ended March 31, 2018 and 2017, respectively, resulting from loans previously modified as TDRs. The following tables present loans, by loan class, modified as TDRs during the three months ended March 31, 2018 and 2017.

Fair Value Disclosures [Abstract]
Fair Value Measurements and Disclosures	9. FAIR VALUE MEASUREMENTS AND DISCLOSURES FASB ASC 820, Fair Value Measurements and Disclosures ASC 820 establishes a fair value hierarchy that prioritizes the inputs to valuation methods used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows: Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Level 2: Quoted prices in markets that are not active, or inputs that are observable either directly or indirectly, for substantially the full term of the asset or liability. Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported with little or no market activity). An asset’s or liability’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The measurement of fair value should be consistent with one of the following valuation techniques: market approach, income approach, and/or cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities (including a business). For example, valuation techniques consistent with the market approach often use market multiples derived from a set of comparables. Multiples might lie in ranges with a different multiple for each comparable. The selection of where within the range the appropriate multiple falls requires judgment, considering factors specific to the measurement (qualitative and quantitative). Valuation techniques consistent with the market approach include matrix pricing. Matrix pricing is a mathematical technique used principally to value debt securities without relying exclusively on quoted prices for the specific securities, but rather by relying on the security’s relationship to other benchmark quoted securities. The following table sets forth QNB’s financial assets measured at fair value on a recurring and nonrecurring basis and the fair value measurements by level within the fair value hierarchy as of March 31, 2018: Quoted in active markets for identical assets (Level 1) Significant other observable input (Level 2) Significant unobservable inputs (Level 3) Balance at end of period Recurring fair value measurements Equity securities $ 9,527 $ — $ — $ 9,527 Debt securities available-for-sale U.S. Government agency securities — 69,772 — 69,772 State and municipal securities — 71,333 — 71,333 U.S. Government agencies and sponsored enterprises (GSEs): Mortgage-backed securities — 133,567 — 133,567 Collateralized mortgage obligations (CMOs) — 74,783 — 74,783 Pooled trust preferred securities — — $ 115 115 Corporate debt securities — 7,949 — 7,949 Total debt securities available-for-sale — 357,404 115 357,519 Total recurring fair value measurements $ 9,527 $ 357,404 $ 115 $ 367,046 Nonrecurring fair value measurements Impaired loans $ — $ — $ 762 $ 762 Mortgage servicing rights — — 7 7 Total nonrecurring fair value measurements $ — $ — $ 769 $ 769 There were no transfers in and out of Level 1 and Level 2 fair value measurements during the three months ended March 31, 2018.

(2) Appraisals may be adjusted by management for qualitative factors such as economic conditions and the age of the appraisal. The range is presented as a percent of the initial appraised value. (3) Appraisals and pending agreements of sale are adjusted by management for estimated liquidation expenses. The range is presented as a percent of the initial appraised value. (4) If lendable value (lower than wholesale) is utilized then no additional discounts are taken. If lendable value is not provided, additional discounts are applied. (5) Values obtained from financial statements for UCC collateral (fixed assets and inventory) are discounted to estimated realizable liquidation value. (6) Fair value is determined by the net amount due. The following table presents additional information about the securities available-for-sale measured at fair value on a recurring basis and for which QNB utilized significant unobservable inputs (Level 3 inputs) to determine fair value for the three months ended March 31, 2018 and 2017: Fair value measurements using significant unobservable inputs (Level 3) 2018 2017 Balance, January 1, $ 215 $ 2,281 Payments received (118 ) (34 ) Total gains or losses (realized/unrealized) Included in earnings — — Included in other comprehensive income 18 176 Transfers in and/or out of Level 3 — — Balance, March 31, $ 115 $ 2,423 The Level 3 securities consist of one collateralized debt obligation security, PreTSL security, which is backed by trust preferred securities issued by banks, thrifts, and insurance companies. As discussed in Note 6, the market for these securities at March 31, 2018 was not active and markets for similar securities also are not active. The inactivity was evidenced first by a significant widening of the bid-ask spread in the brokered markets in which the PreTSLs trade and then by a significant decrease in the volume of trades relative to historical levels. The new issue market is also inactive and there are currently very few market participants who are willing and or able to transact for these securities. Given conditions in the debt markets today and the absence of observable transactions in the secondary and new issue markets, we determined: • The few observable transactions and market quotations that are available are not reliable for purposes of determining fair value at March 31, 2018; • An income valuation approach technique (present value technique) that maximizes the use of relevant observable inputs and minimizes the use of unobservable inputs will be equally or more representative of fair value than the market approach valuation technique used at prior measurement dates; and • PreTSLs will be classified within Level 3 of the fair value hierarchy because significant adjustments are required to determine fair value at the measurement date. The Bank used an independent third party to value this security using a discounted cash flow analysis. Based on management’s review of the bond’s five underlying issuers, there are no expected credit losses or prepayments; cashflows used were contractual based on the Bloomberg YA screen. The assumed cashflows have been discounted using and estimated market discount rate based on the 30-year swap rate. The 30-year is used as the reference rate since it is indicative of market expectation for short-term rates in the future. This is consistent with the 30-year nature of PreTSL securities, which are priced using the 3-month LIBOR as a reference rate. The discount rate of 5.87% includes the risk-free rate, a credit component and a spread for illiquidity. The following information should not be interpreted as an estimate of the fair value of the entire Company since a fair value calculation is only provided for a limited portion of QNB’s assets and liabilities. Due to a wide range of valuation techniques and the degree of subjectivity used in making the estimates, comparisons between QNB’s disclosures and those of other companies may not be meaningful. The following methods and assumptions were used to estimate the fair values of each major classification of financial instrument and non-financial asset at March 31, 2018 and December 31, 2017: Cash and cash equivalents, accrued interest receivable and accrued interest payable (carried at cost) Investment securities - available for sale (carried at fair value) Restricted investment in stocks (carried at cost) Loans Held-for-Sale (carried at lower of cost or fair value) Loans Receivable (carried at cost) Impaired Loans (generally carried at fair value) Mortgage Servicing Rights (carried at lower of cost or fair value) Deposit liabilities (carried at cost) Short-term borrowings (carried at cost) Off-balance-sheet instruments (disclosed at cost) Management uses its best judgment in estimating the fair value of the Company’s financial instruments; however, there are inherent weaknesses in any estimation technique. Therefore, for substantially all financial instruments, the fair value estimates herein are not necessarily indicative of the amounts the Company could have realized in sales transaction on the dates indicated. The estimated fair value amounts have been measured as of the respective period ends and have not been re-evaluated or updated for purposes of these financial statements subsequent to those respective dates. As such, the estimated fair values of these financial instruments subsequent to the respective reporting dates may be different than the amounts reported at each period end. The estimated fair values and carrying amounts of the Company’s financial and off-balance sheet instruments are summarized as follows: Fair value measurements March 31, 2018 Carrying amount Fai r Quoted prices in active markets for identical assets (Level 1) Significant other observable inputs (Level 2) Significant unobservable inputs (Level 3) Financial assets Cash and cash equivalents $ 29,870 $ 29,870 $ 29,870 $ — $ — Investment securities: Equities 9,527 9,527 9,527 — — Available-for-sale 357,519 357,519 — 357,404 115 Restricted investment in stocks 1,466 1,466 — 1,466 — Loans held-for-sale 272 278 — 278 — Net loans 742,150 731,258 — — 731,258 Mortgage servicing rights 474 600 — — 600 Accrued interest receivable 3,697 3,697 — 3,697 — Financial liabilities Deposits with no stated maturities $ 774,118 $ 774,118 $ 774,118 $ — $ — Deposits with stated maturities 232,251 228,647 — 228,647 — Short-term borrowings 64,879 64,879 64,879 — — Accrued interest payable 415 415 — 415 — Off-balance sheet instruments Commitments to extend credit $ — $ — $ — $ — $ — Standby letters of credit — — — 70 — Fair value measurements December 31, 2017 Carrying amount Fai r Quoted prices in active markets for identical assets (Level 1) Significant other observable inputs (Level 2) Significant unobservable inputs (Level 3) Financial assets Cash and cash equivalents $ 16,331 $ 16,331 $ 16,331 $ — $ — Investment securities: Equities 4,975 4,975 4,975 — — Available-for-sale 374,570 374,570 — 374,355 215 Restricted investment in stocks 1,501 1,501 — 1,501 — Loans held-for-sale — — — — — Net loans 725,442 727,341 — — 727,341 Mortgage servicing rights 483 585 — — 585 Accrued interest receivable 3,545 3,545 — 3,545 — Financial liabilities Deposits with no stated maturities $ 768,766 $ 768,766 $ 768,766 $ — $ — Deposits with stated maturities 225,182 223,325 — 223,325 — Short-term borrowings 55,756 55,756 55,756 — — Accrued interest payable 384 384 — 384 — Off-balance sheet instruments Commitments to extend credit $ — $ — $ — $ — $ — Standby letters of credit — — — — —

Commitments And Contingencies Disclosure [Abstract]
Off-balance-sheet Financial Instruments and Guarantees	10. OFF-BALANCE-SHEET FINANCIAL INSTRUMENTS AND GUARANTEES In the normal course of business there are various legal proceedings, commitments, and contingent liabilities which are not reflected in the consolidated financial statements. Management does not anticipate any material losses as a result of these transactions and activities. They include, among other things, commitments to extend credit and standby letters of credit. The maximum exposure to credit loss, which represents the possibility of sustaining a loss due to the failure of the other parties to a financial instrument to perform according to the terms of the contract, is represented by the contractual amount of these instruments. QNB uses the same lending standards and policies in making credit commitments as it does for on-balance sheet instruments. The activity is controlled through credit approvals, control limits, and monitoring procedures. A summary of the Bank's financial instrument commitments is as follows: March 31, December 31, 2018 2017 Commitments to extend credit and unused lines of credit $ 315,913 $ 313,541 Standby letters of credit 14,500 15,211 Total financial instrument commitments $ 330,413 $ 328,752 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require the payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. QNB evaluates each customer’s creditworthiness on a case-by-case basis. Standby letters of credit are conditional commitments issued by the Bank to guarantee the financial or performance obligation of a customer to a third party. QNB’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for standby letters of credit is represented by the contractual amount of those instruments. The Bank uses the same credit policies in making conditional obligations as it does for on-balance sheet instruments. Standby letters of credit of $13,997,000 will expire within one year. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending other loan commitments. The Bank requires collateral and personal guarantees supporting these letters of credit as deemed necessary. Management believes that the proceeds obtained through a liquidation of such collateral and the enforcement of personal guarantees would be sufficient to cover the maximum potential amount of future payments required under the corresponding guarantees. The amount of the liability as of March 31, 2018 and December 31, 2017 for guarantees under standby letters of credit issued is not material. The amount of collateral obtained for letters of credit and commitments to extend credit is based on management’s credit evaluation of the customer. Collateral varies, but may include real estate, accounts receivable, marketable securities, pledged deposits, inventory or equipment.

Banking And Thrift [Abstract]
Regulatory Restrictions	11. REGULATORY RESTRICTIONS Dividends payable by the Company and the Bank are subject to various limitations imposed by statutes, regulations and policies adopted by bank regulatory agencies. Under Federal and Pennsylvania banking law, the Bank is subject to certain restrictions on the amount of dividends that it may declare without prior regulatory approval. Under Federal Reserve regulations, the Bank is limited as to the amount it may lend affiliates, including QNB Corp., unless such loans are collateralized by specific obligations. Both the Company and the Bank are subject to regulatory capital requirements administered by Federal banking agencies. Failure to meet minimum capital requirements can initiate actions by regulators that could have an effect on the financial statements. Under the framework for prompt corrective action, both the Company and the Bank must meet capital guidelines that involve quantitative measures of their assets, liabilities, and certain off-balance-sheet items. The capital amounts and classification are also subject to qualitative judgments by the regulators. Management believes, as of March 31, 2018, that the Company and the Bank met capital adequacy requirements to which they were subject. As of the most recent notification, the primary regulator of the Bank considered it to be “well capitalized” under the regulatory framework. There are no conditions or events since that notification that management believes have changed the classification. To be categorized as well capitalized, the Company and the Bank must maintain minimum ratios as set forth in the following table below. The Company and the Bank’s actual capital amounts and ratios are presented as follows: Capital levels Actual Adequately capitalized Well capitalized As of March 31, 2018 Amount Ratio Amount Ratio Amount Ratio Total risk-based capital (to risk-weighted assets): Consolidated $ 113,230 12.62 % $ 71,801 8.00 % $ 89,751 10.00 % Bank 103,948 11.96 69,513 8.00 86,892 10.00 Tier I capital (to risk-weighted assets): Consolidated 105,120 11.71 53,850 6.00 53,850 6.00 Bank 95,838 11.03 52,135 6.00 69,513 8.00 Common equity tier 1 capital (to risk-weighted assets): Consolidated 105,120 11.71 40,388 4.50 N/A N/A Bank 95,838 11.03 39,101 4.50 56,480 6.50 Tier I capital (to average assets): Consolidated 105,120 9.03 46,575 4.00 N/A N/A Bank 95,838 8.30 46,183 4.00 57,729 5.00 Capital levels Actual Adequately capitalized Well capitalized As of December 31, 2017 Amount Ratio Amount Ratio Amount Ratio Total risk-based capital (to risk-weighted assets): Consolidated $ 110,352 12.52 % $ 70,520 8.00 % $ 88,150 10.00 % Bank 101,040 11.67 69,277 8.00 86,596 10.00 Tier I capital (to risk-weighted assets): Consolidated 102,438 11.62 52,890 6.00 52,890 6.00 Bank 93,126 10.75 51,957 6.00 69,277 8.00 Common equity tier 1 capital (to risk-weighted assets): Consolidated 102,438 11.62 39,668 4.50 N/A N/A Bank 93,126 10.75 38,968 4.50 56,287 6.50 Tier I capital (to average assets): Consolidated 102,438 8.88 46,149 4.00 N/A N/A Bank 93,126 8.14 45,761 4.00 57,201 5.00

[1]	Fair value is primarily determined through appraisals of the underlying collateral by independent parties, which generally includes various level 3 inputs which are not always identifiable.
[2]	Appraisals and pending agreements of sale are adjusted by management for estimated liquidation expenses. The range is presented as a percent of the initial appraised value.
[3]	Appraisals may be adjusted by management for qualitative factors such as economic conditions and the age of the appraisal. The range is presented as a percent of the initial appraised value.
[4]	Values obtained from financial statements for UCC collateral (fixed assets and inventory) are discounted to estimated realizable liquidation value.
