Accounting Policies [Abstract]
Recent Accounting Policies Not Yet Adopted and Adopted	Recent Accounting Policies Not Yet Adopted On March 6, 2024, the Securities and Exchange Commission (SEC) adopted final rules requiring registrants to disclose climate-related information in registration statements and annual reports.

This approach was previously only applied to purchased credit deteriorated (PCD) assets. Purchased seasoned loans are defined as loans that are not PCD assets, credit card receivables, debt securities or trade receivables that are acquired in a business combination, or obtained through a transfer that is not a business combination or initially recognized through the consolidation of a variable interest entity, if certain seasoning criteria are met. A loan is considered seasoned if it is obtained more than 90 days after its origination date and the transferee was not involved in the origination.
Loans	Loans Loans are generally reported at the principal balance outstanding, net of deferred loan fees and costs. Interest income is accrued on the principal amount outstanding. Loan origination and commitment fees net of 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 acquired by QNB through a purchase or business combination are initially evaluated for classification as PCD. Acquired loans are classified as PCD when there is evidence of more than insignificant deterioration in credit quality since origination. Loans that do not meet the criteria to be classified as PCD, are evaluated to determine whether they qualify as PSLs. Loans acquired in a business combination are automatically deemed PSLs. PCD loans and PSLs are accounted for under the gross-up approach, as of the date of acquisition, recognizing an allowance for credit losses (ACL) and an offsetting entry added, or gross-up, to the fair value of the loan; resulting in an initial amortized cost basis in an amount equal to the sum of the purchase price plus the ACL. The difference between the amortized cost basis of the PCD and PSLs (as adjusted for expected credit losses) and the unpaid principal balance is recognized as a noncredit discount or premium and accreted or amortized into interest income over the life of the loan as an adjustment to yield.
Goodwill and Core Deposit Intangibles	Goodwill and Core Deposit Intangibles QNB accounts for its acquisitions using the purchase accounting method. The total purchase price is allocated to the estimated fair values of assets acquired and liabilities assumed, including recognized intangible assets. The excess in the purchase price exceeding the fair value of net assets acquired is recorded as goodwill. Core deposit intangibles are a measure of the value of checking, money market and savings deposits acquired in business combinations accounted for under the purchase method. Core deposit intangibles are amortized using the sum of the year's digits over their estimated useful lives of up to ten years. QNB will perform an assessment of goodwill and other identifiable intangible assets at least annually, or more often if events and circumstances indicate, that an impairment test should be performed.

Recent Accounting Policies Adopted

QNB adopted FASB issued ASU 2025-08--Finance Instruments--Credit Losses (Topic 326): Purchased Loans, amending ASC 326 to expand use of the gross-up approach in ASC 326, Credit Losses, to all purchased seasoned loans (PSLs). This approach was previously only applied to purchased credit deteriorated (PCD) assets.

A loan is considered seasoned if it is obtained more than 90 days after its origination date and the transferee was not involved in the origination.

Loans

Loan origination and commitment fees net of 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 acquired by QNB through a purchase or business combination are initially evaluated for classification as PCD. Acquired loans are classified as PCD when there is evidence of more than insignificant deterioration in credit quality since origination. Loans that do not meet the criteria to be classified as PCD, are evaluated to determine whether they qualify as PSLs. Loans acquired in a business combination are automatically deemed PSLs.

Goodwill and Core Deposit Intangibles

QNB accounts for its acquisitions using the purchase accounting method. The total purchase price is allocated to the estimated fair values of assets acquired and liabilities assumed, including recognized intangible assets. The excess in the purchase price exceeding the fair value of net assets acquired is recorded as goodwill.

Core deposit intangibles are a measure of the value of checking, money market and savings deposits acquired in business combinations accounted for under the purchase method. Core deposit intangibles are amortized using the sum of the year's digits over their estimated useful lives of up to ten years.

QNB will perform an assessment of goodwill and other identifiable intangible assets at least annually, or more often if events and circumstances indicate, that an impairment test should be performed.
