Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies The following is a summary of significant accounting policies followed in the preparation of the consolidated financial statements: Principles of Consolidation The consolidated financial statements include the accounts of Park National Corporation and its subsidiaries (“Park”, the “Company” or the “Corporation”), unless the context otherwise requires. Material intercompany accounts and transactions have been eliminated. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP") requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. The COVID-19 pandemic and subsequent economic uncertainty have caused significant, unprecedented disruption around the world that has affected daily living and negatively impacted the global economy. Additionally, geopolitical conflict (including the conflict in Ukraine) and inflationary pressures have added uncertainty to the overall economic environment. The effects of the COVID-19 pandemic, geopolitical conflict, and inflationary pressures may meaningfully impact significant estimates such as the allowance for credit losses, goodwill, and pension plan obligations and related expenses. Reclassifications Certain prior year amounts have been reclassified to conform with the current presentation. These reclassifications had no impact on net income or shareholders' equity. Restrictions on Cash and Due from Banks As of March 26, 2020, the Federal Reserve Board eliminated reserve requirements for all depository institutions.There were no compensating balance arrangements in existence at December 31, 2022 or 2021. Investment Securities Debt securities are classified upon acquisition into one of three categories: HTM, AFS, or trading (see Note 4 - Investment Securities). HTM securities are those debt securities that the Corporation has the positive intent and ability to hold to maturity and are recorded at amortized cost. AFS debt securities are those debt securities that would be available to be sold in the future in response to the Corporation’s liquidity needs, changes in market interest rates, and asset-liability management strategies, among other reasons. AFS debt securities are reported at fair value, with unrealized holding gains and losses excluded from earnings, but included in other comprehensive (loss) income, net of applicable income taxes. The Corporation did not hold any trading securities during any period presented. Interest income from debt securities includes amortization of purchase premium or discount. Premiums and discounts on investment securities are amortized on the level-yield method without anticipating prepayments, except for mortgage-backed securities where prepayments are anticipated. Premiums on callable debt securities are amortized to their earliest call date. Gains and losses realized on the sale of debt securities are recorded on the trade date and determined using the specific identification method. A debt security is placed on nonaccrual status at the time any principal or interest payments become 90 days past due. Interest accrued but not received for a security placed on nonaccrual status is reversed against interest income. ACL - Debt Securities AFS For debt securities AFS in an unrealized loss position, Park first assesses whether it intends to sell, or it is more likely than not that Park will be required to sell, the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security's amortized cost basis is written down to fair value through net income. For debt securities AFS that do not meet the aforementioned criteria, Park evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security is compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income (loss), net of applicable taxes. Changes in the ACL are recorded as a provision for (or recovery of) credit loss expense. Losses are charged against the ACL when management believes that uncollectibility of a debt security AFS is confirmed or when either of the criteria regarding intent or requirement to sell is met. Accrued interest receivable on debt securities AFS totaled $12.4 million and $6.3 million at December 31, 2022 and 2021, respectively, and is excluded from the estimate of credit losses. ACL - HTM Debt Securities Management measures expected credit losses on HTM debt securities on a collective basis by major security type. The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. Park does not currently hold any HTM debt securities. Equity Securities Equity securities, included within "Other investment securities" on the Consolidated Balance Sheets, are carried at fair value, with changes in fair value reported in net income. Equity securities without readily determinable fair values are carried at cost, minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment. Federal Home Loan Bank and Federal Reserve Bank of Cleveland Stock PNB is a member of the FHLB and the FRB. Members are required to own a certain amount of stock based on their level of borrowings and other factors and may invest in additional amounts. FHLB stock and FRB stock are classified as restricted securities and are carried at their redemption value within "Other investment securities" on the Consolidated Balance Sheets. Impairment is evaluated based on the ultimate recovery of par value. Both cash and stock dividends are reported as income. Loans Held for Sale Park has elected the fair value option for mortgage loans held for sale, which are carried at their fair value as of each balance sheet date. Mortgage Banking Derivatives Commitments to fund mortgage loans (interest rate locks) to be sold into the secondary market and forward commitments for the future delivery of these mortgage loans are accounted for as free standing derivatives. The fair value of an interest rate lock is recorded at the time the commitment to fund a mortgage loan is executed and is adjusted for the expected exercise of a commitment before a loan is funded. In order to hedge against a change in interest rates resulting from the Company's commitments to fund loans, the Company enters into forward commitments for the future delivery of mortgage loans. The fair value of Park's mortgage banking derivatives is estimated based on the change in mortgage interest rates from the date the interest on a loan is locked. The fair value of these mortgage banking derivatives is included in "Loans" in the Consolidated Balance Sheets. Changes in the fair value of these mortgage banking derivatives are included in "Other service income" in the Consolidated Statements of Income. Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at amortized cost. Amortized cost is the principal balance outstanding, net of purchase premiums and discounts and deferred loan fees and costs. Interest income is accrued on the unpaid principal balance. Accrued interest receivable totaled $22.3 million and $17.1 million at December 31, 2022 and 2021, respectively, and was reported in "Accrued interest receivable" on the Consolidated Balance Sheets. Late charges on loans are recognized as income when they are collected. Net loan origination fees and costs are deferred and recognized in interest income using the level-yield method without anticipating prepayments. Commercial loans include: (1) commercial, financial and agricultural loans; (2) commercial real estate loans; (3) those commercial loans in the construction real estate loan segment; (4) those commercial loans in the residential real estate loan segment; and (5) leases. Consumer loans include: (1) mortgage and installment loans included in the construction real estate segment; (2) mortgage, home equity lines of credit ("HELOCs"), and installment loans included in the residential real estate segment; and (3) all loans included in the consumer segment. Generally, commercial loans are placed on nonaccrual status at 90 days past due and consumer and residential mortgage loans are placed on nonaccrual status at 120 days past due. The delinquency status of a loan is based on contractual terms and not on how recently payments have been received. Park’s charge-off policy for commercial loans requires management to establish a specific reserve or record a charge-off when collection is in doubt and there is, or likely will be, a collateral shortfall related to the estimated value of the collateral securing a loan. The Company’s charge-off policy for consumer loans is dependent on the class of the loan. Residential mortgage loans, HELOCs, and consumer loans secured by residential real estate are typically charged down to the value of the collateral, less estimated selling costs, at 180 days past due. The charge-off policy for other consumer loans, primarily installment loans, requires a monthly review of delinquent loans and a complete charge-off for any account that reaches 120 days past due. In all cases, loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful. For loans which are on nonaccrual status, it is Park’s policy to reverse interest previously accrued on the loans against interest income. Interest on such loans may be recorded on a cash basis and be included in earnings only when Park expects to receive the entire recorded investment of the respective loans. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. A description of each segment of the loan portfolio, along with the risk characteristics of each segment, is included below: Commercial, financial and agricultural: Commercial, financial and agricultural ("C&I") loans are made for a wide variety of general corporate purposes, including financing for commercial and industrial properties, financing for equipment, inventory and accounts receivable, acquisition financing, commercial leasing, and loans originated by consumer finance companies. The term of each commercial loan varies by its purpose. Repayment terms are structured such that commercial loans will be repaid within the economic useful life of the underlying asset. Risk of loss on C&I loans largely depends upon general economic cycles, as they may adversely impact certain industries, competency of the borrower's management team, the quality of the underlying assets supporting the loans including accounts receivable, inventory, and equipment, and the accuracy of the borrower's financial reporting. Such risks are mitigated by generally requiring the borrower's owners to guaranty the loans. Commercial real estate: Commercial real estate (“CRE”) loans include mortgage loans to developers and owners of commercial real estate. The lending policy for CRE loans is designed to address the unique risk attributes of CRE lending. The collateral for these CRE loans is the underlying commercial real estate. Risk of loss on CRE loans largely depends upon the cash flow of the properties, which is influenced by the amount of vacancy experienced with respect to underlying real estate, the credit capacity of the tenants occupying the underlying real estate, and general economic trends, as they may adversely impact the value of a property. These risks are mitigated by generally requiring personal guarantees of the owners of the properties and by requiring appraisals pursuant to government regulations. Construction real estate : The Company defines construction loans as both commercial construction loans and residential construction loans where the loan proceeds are used exclusively for the improvement of real estate. Construction loans may be in the form of a permanent loan or a short-term construction loan, depending on the needs of the individual borrower. Construction financing is generally considered to involve a higher degree of risk of loss than long-term financing on improved, occupied real estate. Risk of loss on a construction loan depends largely upon the accuracy of the initial estimate of the property’s value at completion of construction and the estimated cost (including interest) of construction. If the estimate of construction cost proves to be inaccurate, Park may be required to advance funds beyond the amount originally committed to permit completion of the project. If the estimate of value proves inaccurate, Park may be confronted, at or prior to the maturity of the loan, with a project having a value insufficient to assure full repayment, should the borrower default. In the event that a default on a construction loan occurs and foreclosure follows, Park must take control of the project and attempt to either arrange for completion of construction or dispose of the unfinished project. Additional risks exist with respect to loans made to developers who do not have a buyer for the property, as the developer may lack funds to pay the loan if the property is not sold upon completion. Park attempts to reduce such risks on loans to developers by generally requiring personal guarantees and reviewing current personal financial statements and tax returns as well as other projects undertaken by the developer. Residential real estate: The Company defines residential real estate loans as first mortgages on individuals’ primary residences or second mortgages on individuals’ primary residences in the form of HELOCs or installment loans. Credit approval for residential real estate loans requires demonstration of sufficient income to repay the principal and interest and the real estate taxes and insurance, stable employment, an established credit record and a current independent third-party appraisal providing the market value of the real estate securing the loan. Residential real estate loans typically have longer terms and higher balances with lower yields as compared to consumer loans, but generally carry lower risks of default. The Dodd-Frank Wall Street Reform and Consumer Protection Act requires creditors to make a reasonable and good faith determination of a consumer's ability to repay any consumer credit transaction secured by a dwelling. Documentation and verification of income within defined time frames and not-to-exceed limits are bases for affirming ability to repay. Risk of loss largely depends upon factors affecting the borrower's ability to repay as well as the general economic trends as they may adversely impact the value of the property. These risks are mitigated by completing a comprehensive underwriting of the borrower and by requiring appraisals pursuant to government regulations. Consumer: The Company originates direct and indirect consumer loans, primarily automobile loans, to customers in the Company's primary market areas. Credit approval for consumer loans requires income sufficient to repay principal and interest due, stable employment, an established credit record and sufficient collateral for secured loans. Consumer loans typically have shorter terms and lower balances with higher yields as compared to real estate mortgage loans, but generally carry higher risks of default. Consumer loan collections are dependent on the borrower’s financial stability, and thus are more likely to be affected by adverse personal circumstances. Leases : The Company originates financing leases primarily for the purchase of commercial vehicles, operating/manufacturing equipment, and municipal vehicles/equipment. Repayment terms are structured such that the lease will be repaid within the economic useful life of the leased asset. Risk of losses on financing leases largely depends upon general economic cycles, as they may adversely impact certain industries, competency of the borrower’s management team, the quality and residual value of the leased asset, and the accuracy of the borrower’s financial reporting. These risks are mitigated by underwriting leases considering primary and secondary sources of repayment and requiring guaranteed residual values. Concentration of Credit Risk Park's commercial loan portfolio includes loans to a wide variety of corporations and businesses across many industrial classifications in the 26 Ohio counties, four North Carolina counties, four South Carolina counties and one Kentucky county where PNB operates, with the exception of nationwide aircraft loans and nationwide asset-based lending to consumer finance companies. The primary industries represented by these customers include real estate rental and leasing, finance and insurance, construction, accommodation and food services, health care and social assistance, other services, manufacturing, retail trade, and agriculture, forestry, fishing and hunting. PCD Loans The Company has purchased loans, some of which have shown evidence of credit deterioration since origination. Upon adoption of ASC 326, Park elected to maintain pools of loans that were previously accounted for under ASC 310-30 and will continue to account for these pools as a unit of account. Loans are only removed from the existing pools if they are written off, paid off, or sold. Upon adoption of ASC 326, the allowance for credit losses was determined for each pool and added to the pool's carrying amount to establish a new amortized cost basis. The difference between the unpaid principal balance of the pool and the new amortized cost basis is the noncredit premium or discount, which will be amortized into interest income over the remaining life of the pool. Changes to the allowance for credit losses after adoption are recorded through provision for credit losses expense. ACL - Loans The ACL is a valuation account that is deducted from the amortized cost of total loans to present the net amount expected to be collected on the loans. Loans are charged off against the allowance when management believes that the uncollectibility of a loan balance is confirmed. Expected recoveries cannot exceed the aggregate of the amounts previously charged-off and expected to be charged-off. Management estimates the allowance balance using relevant and available information from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical credit loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, delinquency level, or term as well as changes in environmental conditions, such as changes in unemployment rates, property values, or other relevant factors. ACL - Loans - Collectively Evaluated The ACL is measured on a collective pool basis when similar risk characteristics exist. Park has identified the following portfolio segments and measures the allowance for credit losses using the following methods: Portfolio Segment Measurement Method Loss Driver Commercial, financial and agricultural Commercial, financial and agricultural Discounted Cash Flow Ohio Unemployment, Ohio GDP PPP loans Other Not Applicable Overdrafts Historical Loss Experience Not Applicable Commercial real estate Discounted Cash Flow Ohio Unemployment, Ohio GDP Construction real estate: Commercial Discounted Cash Flow Ohio Unemployment, Ohio GDP Retail Discounted Cash Flow Ohio Unemployment, Ohio GDP Residential real estate: Commercial Discounted Cash Flow Ohio Unemployment, Ohio HPI Mortgage Discounted Cash Flow Ohio Unemployment, Ohio HPI HELOC Discounted Cash Flow Ohio Unemployment, Ohio HPI Installment Discounted Cash Flow Ohio Unemployment, Ohio HPI Consumer: Consumer Discounted Cash Flow Ohio Unemployment, Ohio GDP GFSC Discounted Cash Flow Ohio Unemployment, Ohio GDP Check loans Historical Loss Experience Not Applicable Leases Remaining Life Not Applicable Expected credit losses are estimated over the contractual term of the loans, adjusted for prepayments when appropriate. The contractual term excludes extensions, renewals, and modifications unless either of the following applies: management has a reasonable expectation at the reporting date that a TDR will be executed with an individual borrower or the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancellable by Park. In general, Park utilized a DCF method to estimate the quantitative portion of the allowance for credit losses for loans evaluated on a collective pooled basis. For each segment, a LDA was performed in order to identify appropriate loss drivers and create a regression model for use in forecasting cash flows. The LDA utilized Park's own Federal Financial Institutions Examination Council's ("FFIEC") Call Report data for the commercial, financial and agricultural and residential real estate segments. Peer data was incorporated into the analysis for the commercial real estate, construction real estate, and consumer segments. In creating the DCF model, Park established a one-year reasonable and supportable forecast period with a one-year straight line reversion to the long-term historical average. Park's policy is to utilize its own data, which includes loan-level loss data from 2013 through December 31, 2022, whenever possible. Park and peer FFIEC Call Report data are utilized when there are insufficient defaults for a statistically sound calculation, or if Park does not have its own loan-level detail reflecting similar economic conditions as the forecasted loss drivers. Key inputs into the DCF model include loan-level detail, including the amortized cost basis of individual loans, payment structure, loss history, and forecasted loss drivers. Park utilizes a third party to provide economic forecasts under various scenarios, which are weighted in order to reflect model risk in the then current economic environment. The weighting of the scenarios is evaluated on a quarterly basis considering the various scenarios in the context of the then current economic environment and presumed risk of loss. Additional key assumptions in the DCF model include the PD, LGD, and prepayment/curtailment rates. When possible, Park utilizes its own PDs for the reasonable and supportable forecast period. When it is not possible to use Park's own PDs, the LDA is utilized to determine PDs based on the forecasted economic factors. In all cases, the LDA is then utilized to determine the long-term historical average, which is reached over the reversion period. When possible, Park's utilizes its own LGDs for the reasonable and supportable forecast period. When it is not possible to use Park's own LGDs, the LGD is derived using a method referred to as Frye Jacobs. The Frye Jacobs method is a mathematical formula that traces the relationship between LGD and PD over time and projects the LGD based on the level of PD forecasted. In all cases, the Frye Jacobs method is utilized to calculate LGDs during the reversion period and long-term historical average. Prepayment and curtailment rates were calculated based on Park's own data utilizing a three-year average. When the discounted cash flow method is used to determine the allowance for credit losses, management incorporates expected prepayments to determine the effective interest rate utilized to discount expected cash flow. Park reviews various internal and external factors to consider the need for any qualitative adjustments to the quantitative model. Factors considered include the following: • The nature and volume of Park’s financial assets; • The existence, growth, and effect of any concentrations of credit; • The volume and severity of past due financial assets, the volume of nonaccrual assets, and the volume and severity of adversely classified or graded assets; • Park’s lending policies and procedures, including changes in lending strategies, underwriting standards and practices for collections, write-offs, and recoveries; • The quality of Park's credit review function; • The experience, ability, and depth of Park’s lending, investment, collection, and other relevant management and staff; • The effect of other external factors such as the regulatory, legal and technological environments, competition, geopolitical conflict, and events such as natural disasters or pandemics; • Actual and expected changes in international, national, regional, and local economic and business conditions and developments in the markets in which Park operates that affect the collectibility of financial assets; • Where the U.S. economy is within a given credit cycle; and • The extent that there is government assistance (stimulus). Allowance for Credit Losses - Loans - Individually Evaluated Loans that do not share risk characteristics are evaluated on an individual basis and are excluded from the collective evaluation. Park has determined that any commercial loans which have been placed on nonaccrual status or classified as TDRs are to be individually evaluated. Individual analysis establishes a specific reserve for loans in scope. Specific reserves on individually evaluated commercial loans are typically based on management’s best estimate of the fair value of collateral securing these loans, adjusted for selling costs as appropriate. Allowance for Credit Losses - Off-Balance Sheet Credit Exposures Park estimates expected credit losses over the contractual period in which Park is exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by Park. The allowance for credit losses on off-balance sheet credit exposures is adjusted within "Miscellaneous other expense" on the Consolidated Statements of Income. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over the commitments' respective estimated lives. Funding rates are based on a historical analysis of Park's portfolio, while estimates of credit losses are determined using the same loss rates as funded loans. Troubled Debt Restructurings ("TDRs") Management classifies loans as TDRs when a borrower is experiencing financial difficulty and Park has granted a concession. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of the borrower's debt in the foreseeable future without the modification. This evaluation is performed under the Company’s internal underwriting policy. Management’s policy is to modify loans by extending the term or by granting a temporary or permanent contractual interest rate below the market rate, not by forgiving debt. A court's discharge of a borrower's debt in a Chapter 7 bankruptcy is considered a concession when the borrower does not reaffirm the discharged debt. Additionally, during the COVID-19 pandemic, Park worked with borrowers and provided modifications in the form of either interest only deferral or principal and interest deferral, in each case, for initial periods up to 90 days. As necessary, Park made available a second 90-day interest only deferral or principal and interest deferral bringing the total potential deferral period to six months. A majority of these modifications were excluded from TDR classification under Section 4013 of the CARES Act or under applicable interagency guidance of the federal banking regulators. In accordance with this guidance, such modified loans were considered current and continued to accrue interest during the deferral period. Bank Owned Life Insurance Park has purchased insurance policies on the lives of directors and certain key officers. Bank owned life insurance is recorded at its cash surrender value (or the amount that can be realized). Goodwill and Other Intangible Assets Goodwill represents the excess of the purchase price over net identifiable tangible and intangible assets acquired in a purchase business combination. Goodwill is not amortized to expense, but is subject to impairment tests annually, or more frequently, if events or changes in circumstances indicate that the asset might be impaired, by assessing qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If after assessing these events or circumstances, it is concluded that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then the performance of additional analysis is unnecessary. If the carrying amount of the goodwill exceeds the fair value, an impairment charge must be recorded in an amount equal to the excess, not to exceed the total goodwill allocated to the reporting unit. Other intangible assets consist of core deposit intangibles. Core deposit intangibles are amortized on an accelerated basis over a period of ten years. Premises and Equipment Land is carried at cost and is not subject to depreciation. Premises and equipment are carried at cost, less accumulated depreciation and amortization. Depreciation is generally provided on the straight-line method over the estimated useful lives of the related assets. Leasehold improvements are amortized over the shorter of the remaining lease period or the estimated useful lives of the improvements. Upon the sale or other disposal of an asset, the cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is recognized. Maintenance and repairs are charged to expense as incurred while renewals and improvements that extend the useful life of an asset are capitalized. Premises and equipment are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount of a particular asset may not be recoverable. The range of depreciable lives over which premises and equipment are being depreciated are: Buildings 30 Years Building improvements 5 to 10 Years Equipment, furniture and fixtures 3 to 12 Years Software 3 Years or the contractual useful life of the software Leasehold improvements Shorter of the remaining lease period or the estimated useful life of the improvement Other Real Estate Owned Management transfers a loan to OREO at the time that Park takes deed/title to the asset. OREO is initially recorded at fair value less anticipated selling costs (net realizable value), establishing a new cost basis, and consists of property acquired through foreclosure and real estate held for sale. If the net realizable value is below the carrying value of the loan at the date of transfer, the difference is charged to the allowance for credit losses. If the net realizable value is above the carrying value of the loan at the date of transfer, any charged-off amounts are recovered and any additional amount is recorded within the line item "OREO valuation markup." These assets are subsequently accounted for at the lower of cost or fair value less costs to sell. Subsequent changes in the value of real estate are classified as OREO valuation adjustments, are reported as adjustments to the carrying amount of OREO, and recorded within the line item “Miscellaneous income". In certain circumstances where management believes the devaluation may

Accounting Standards Update and Change in Accounting Principle [Abstract]
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	Adoption of New Accounting Pronouncements and Issued But Not Yet Effective Accounting Standards The following is a summary of new accounting pronouncements impacting Park's consolidated financial statements, and accounting standards that have been issued but were not effective for Park as of December 31, 2022: Adoption of New Accounting Pronouncements ASU 2016-13 - Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments: Effective January 1, 2021, Park adopted ASU 2016-13 - Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("ASU 2016-13") ("ASC 326"), as amended. The accounting guidance in ASU 2016-13 replaces the incurred loss methodology with an expected loss methodology, which is referred to as the current expected credit loss ("CECL") methodology. The CECL methodology is applicable to the measurement of credit losses on financial assets measured at amortized cost, including loan receivables, HTM debt securities, and reinsurance receivables. It also applies to off-balance sheet credit exposures not accounted for as insurance (loan commitments, standby letters of credit, financial guarantees, and other similar instruments), and net investments in leases recognized by a lessor. The CECL methodology requires an entity to estimate credit losses over the life of an asset or off-balance sheet credit exposure. Park adopted ASC 326 using the modified retrospective method for all financial assets measured at amortized cost and off-balance sheet credit exposures. Results for reporting periods beginning on and after January 1, 2021 are presented under ASC 326, while prior period amounts continue to be reported in accordance with the then applicable U.S. GAAP. Park recorded a net decrease to retained earnings of $8.0 million as of January 1, 2021 for the cumulative effect of adopting ASC 326. Park adopted ASC 326 using the prospective transition approach for financial assets PCD that were previously classified as PCI and accounted for under ASC 310-30. In accordance with ASC 326, management did not reassess whether PCI assets met the criteria of PCD assets as of the date of adoption. On January 1, 2021, the amortized cost basis of the PCD assets was adjusted to reflect the addition of $52,000 to the allowance for credit losses. The remaining noncredit discount (based on the adjusted amortized cost basis) will be accreted into interest income at the effective interest rate as of January 1, 2021. As permitted by ASC 326, Park elected to maintain pools of loans accounted for under ASC 310-30. In accordance with ASC 326, management did not reassess whether modifications to individual acquired financial assets accounted for in pools were TDRs as of the date of adoption. The following table illustrates the impact of ASC 326: January 1, 2021 (In thousands) As Reported Under ASC 326 Pre-ASC 326 Adoption Impact of ASC 326 Adoption Assets: Loans $ 7,177,666 $ 7,177,785 $ (119) ACL on loans Commercial, financial and agricultural 17,351 25,608 (8,257) Commercial real estate 25,599 23,480 2,119 Construction real estate 5,390 7,288 (1,898) Residential real estate 14,484 11,363 3,121 Consumer 28,343 17,418 10,925 Leases 598 518 80 Total ACL on loans $ 91,765 $ 85,675 $ 6,090 Liabilities: ACL on off-balance sheet commitments $ 3,982 $ 116 $ 3,866 Net deferred tax liability 777 2,892 (2,115) Shareholders' equity: $ 1,032,300 $ 1,040,256 $ (7,956) ASU 2020-04 - Reference Rate Reform (Topic 848): Facilitation of the Effect of Reference Rate Reform on Financial Reporting : In March 2020, the FASB issued ASU 2020-04 - Reference Rate Reform (Topic 848): Facilitation of the Effect of Reference Rate Reform on Financial Reporting . The amendments in this ASU provide optional expedients and exceptions to applying GAAP to contracts, hedging relationships and other transactions impacted by reference rate reform if certain criteria are met. The amendments in this ASU were officially effective as of March 12, 2020 through December 31, 2022 but were extended by ASU 2022-06 as described below. The adoption of this guidance did not have a material impact on Park's consolidated financial statements, but Park will consider this guidance as contracts are transitioned from LIBOR to another reference rate. Staff Accounting Bulletin ("SAB") No. 121: In March 2022, the SEC issued SAB No. 121. This SAB adds interpretive guidance for entities to consider when they have obligations to safeguard crypto-assets held for their platform users. Specifically, this SAB provides interpretive guidance on the accounting and disclosure of obligations to safeguard crypto-assets held for platform users. This guidance was applicable no later than the financial statement covering the first interim or annual period ending after June 15, 2022. Management reviewed its business activities as of the date of adoption, June 30, 2022, and determined that SAB 121 was not materially impactful to the consolidated financial statements. Management has continued to monitor the impact of the guidance on a quarterly basis and determined that SAB 121 was not materially impactful to the financial statements at December 31, 2022. ASU 2022-06 - Reference Rate Reform (Topic 848) Deferral of the Sunset Date of Topic 848: In December 2022, the FASB issued ASU 2022-06 - Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848. ASU 2022-06 was issued to extend the period of time preparers can use the reference rate reform relief guidance under the ASC Topic 848 from December 31, 2022 to December 31, 2024. The FASB had previously included a sunset provision within Topic 848 based on expectations of when the LIBOR would cease being published. At the time that ASU 2020-04 - Reference Rate Reform (Topic 848): Facilitation of the Effect of Reference Rate Reform on Financial Reporting was issued, the UK Financial Conduct Authority had established the intent that it would no longer be necessary for banks to submit to LIBOR after December 31, 2021. As a result, the sunset provision was set for December 31, 2022, 12 months after the expected cessation date of all currencies and tenors of LIBOR. In March 2021, the UK Financial Conduct Authority announced that the intended cessation date of LIBOR would be June 30, 2023, which is beyond the current sunset date of Topic 848 . The amendments of ASU 2022-06 were effective immediately. The adoption of this guidance did not have a material impact on Park's consolidated financial statements, but Park will consider this guidance as contracts are transitioned from LIBOR to another reference rate. Issued But Not Yet Effective Accounting Standards ASU 2022-02 - Financial Instruments - Credit Losses (Topic 326) Troubled Debt Restructurings and Vintage Disclosures: In March 2022, FASB issued ASU 2022-02 - Financial Instruments - Credit Losses (Topic 326) Troubled Debt Restructuring and Vintage Disclosures . ASU 2022-02 eliminates the accounting guidance for TDRs by creditors in Subtopic 310-40, Receivables - Troubled Debt Restructurings by Creditors , while enhancing disclosure requirements for certain loan refinancing and restructurings by creditors when a borrower is experiencing financial difficulty. Additionally, the amendments in this ASU require that public business entities disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20, Financial Instruments - Credit Losses - Measured at Amortized Cost. For entities, like Park, that have adopted the amendments in ASU 2016-13, the amendments in ASU 2022-02 are effective for fiscal years beginning after December 15, 2022, including interim periods within those years. Early adoption is permitted, including adoption in an interim period. An entity may elect to adopt the loan modification guidance and related disclosure enhancements separately from the amendments related to vintage disclosures. The amendments in ASU 2022-02 are to be applied prospectively, except for the amendments related to the recognition and measurement of TDRs which may be applied prospectively, or using a modified retrospective transition method. The adoption by Park of ASU 2022-02 on January 1, 2023 is not expected to have a material impact on the consolidated financial statements but will impact future disclosure requirements and reduce individually evaluated loan totals.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization Park National Corporation is a financial holding company headquartered in Newark, Ohio. Through PNB, Park is engaged in a general commercial banking and trust business, primarily in Ohio, Kentucky, North Carolina, and South Carolina, with the exception of nationwide aircraft loans and nationwide asset-based lending to consumer finance companies. PNB is headquartered in Newark, Ohio. A wholly-owned subsidiary of Park, GFSC is a consumer finance company located in Central Ohio. Through February 16, 2012, Park operated a second banking subsidiary, Vision Bank ("Vision"), which was engaged in a general commercial banking business, primarily in Baldwin County, Alabama and the panhandle of Florida. Promptly following the sale of the Vision business to Centennial Bank (a wholly-owned subsidiary of Home BancShares, Inc.), Vision surrendered its Florida banking charter to the Florida Office of Financial Regulation and became a non-bank Florida corporation. Vision (the Florida corporation) merged with and into a wholly-owned, non-bank subsidiary of Park, SEPH, with SEPH being the surviving entity. SEPH holds the remaining assets and liabilities retained by Vision subsequent to the sale to Centennial Bank. SEPH also holds OREO that had previously been transferred to SEPH from Vision. SEPH's assets consist primarily of nonperforming loans and OREO. This non-bank subsidiary represents a run off portfolio of the legacy Vision assets. PNB provides the following principal services: the acceptance of deposits for demand, savings and time accounts; commercial, industrial, consumer and real estate lending, including installment loans, credit cards (which are largely offered through a third party), home equity lines of credit and commercial leasing; trust and wealth management services; cash management; safe deposit operations; electronic funds transfers; and a variety of additional banking-related services.

The following table provides detail on investment securities in an unrealized loss position for which an allowance for credit losses had not been recorded at December 31, 2022 and December 31, 2021, aggregated by major security type and length of time in a continuous unrealized loss position: Less than 12 Months 12 Months or Longer Total (In thousands) Fair Value Unrealized Losses Fair Value Unrealized Losses Fair Value Unrealized Losses 2022: Debt Securities Available-for-Sale Obligations of U.S. Government sponsored entities $ 37,213 $ 1,787 $ — $ — $ 37,213 $ 1,787 Obligations of states and political subdivisions 270,905 18,194 — — 270,905 18,194 U.S. Government sponsored entities’ asset-backed securities 446,423 27,507 310,338 55,131 756,761 82,638 Collateralized loan obligations 415,491 15,446 101,048 3,533 516,539 18,979 Corporate debt securities 7,388 862 1,684 316 9,072 1,178 Total $ 1,177,420 $ 63,796 $ 413,070 $ 58,980 $ 1,590,490 $ 122,776 Less than 12 Months 12 Months or Longer Total (In thousands) Fair Value Unrealized Losses Fair Value Unrealized Losses Fair Value Unrealized Losses 2021: Debt Securities Available-for-Sale Obligations of states and political subdivisions $ 1,834 $ 24 $ — $ — $ 1,834 $ 24 U.S. Government sponsored entities’ asset-backed securities 333,653 4,996 73,431 3,092 407,084 8,088 Collateralized loan obligations 429,671 1,395 — — 429,671 1,395 Corporate debt securities 2,243 7 — — 2,243 7 Total $ 767,401 $ 6,422 $ 73,431 $ 3,092 $ 840,832 $ 9,514 At December 31, 2022, Park’s debt security portfolio consisted of $1.7 billion of securities, $1.6 billion of which were in an unrealized loss position with unrealized losses of $122.8 million. Of the $1.6 billion of securities in an unrealized loss position, $413.1 million were in an unrealized loss position for 12 months or longer. Of the $122.8 million in unrealized losses, an aggregate of $84.4 million were related to Park's "Obligations of U.S. Government sponsored entities" portfolio and Park's "U.S. Government sponsored entities' asset-backed securities" portfolio. For non-agency debt securities, Park verified that the current credit ratings remain above investment grade. Management periodically reviews the credit profile of each non-agency debt security and assesses whether any impairment to the contractually obligated cash flow is likely to occur. Based on these reviews, management has concluded that the underlying creditworthiness for each security remains sufficient to maintain required payment obligations and, therefore, unrealized losses have not been recognized into net income. Management does not intend to sell, and it is not more likely than not that management would be required to sell, the securities prior to their anticipated recovery in respect of the unrealized losses. Management believes the value will recover as the securities approach maturity or market rates change. There was no allowance for credit losses recorded for debt securities AFS at December 31, 2022 and December 31, 2021. Additionally, for the years ended December 31, 2022, 2021, and 2020, there were no credit-related investment impairment losses recognized. The amortized cost and estimated fair value of investments in debt securities at December 31, 2022, are shown in the following table by contractual maturity, except for asset-backed securities and collateralized loan obligations, which are shown as a single total, due to the unpredictability of the timing in principal repayments. Expected maturities may differ from contractual maturities if borrowers have the right to call or prepay obligations with or without call or prepayment penalties.

At December 31, 2022, investment securities with an amortized cost of $452.2 million were pledged for government and public fund deposits, $353.0 million were pledged to secure repurchase agreements and $7.2 million were pledged as collateral for FHLB advance borrowings. At December 31, 2021, investment securities with an amortized cost of $396.3 million were pledged for government and public fund deposits, $327.9 million were pledged to secure repurchase agreements and $9.5 million were pledged as collateral for FHLB advance borrowings. At December 31, 2022, there were no holdings of securities of any one issuer, other than the U.S. Government and its agencies, in an amount greater than 10% of shareholders’ equity. There were no sales of AFS debt securities during 2022 and 2021. During 2020, Park sold certain AFS debt securities with a book value of $112.5 million at a gross loss of $64,000 and sold certain AFS debt securities with a book value of $196.4 million at a gross gain of $3.4 million. Other Investment Securities Other investment securities (as shown on the Consolidated Balance Sheets) consist of restricted stock investments in the FHLB and the FRB, and equity securities. The FHLB and FRB restricted stock investments are carried at their redemption value. Equity securities with a readily determinable fair value are carried at fair value. Equity securities without a readily determinable fair value are recorded at cost, minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions ("modified cost"). Park's portfolio of equity investments in limited partnerships which provide mezzanine funding ("Partnership Investments") are valued using the net asset value practical expedient in accordance with ASC 820. The carrying amount of other investment securities at December 31, 2022 and 2021 was as follows: (In thousands) December 31, 2022 December 31, 2021 FHLB stock $ 11,197 $ 13,413 FRB stock 14,653 14,653 Equity investments carried at fair value 1,859 2,129 Equity investments carried at modified cost (1) 14,725 4,689 Equity investments carried at net asset value 44,657 26,384 Total other investment securities $ 87,091 $ 61,268 (1) There have been no impairments or downward adjustments made to equity investments carried at modified cost.

Credit Quality Indicators Management utilizes past due information as a credit quality indicator across the loan portfolio. Past due information at December 31, 2022 and December 31, 2021 is included in the previous tables. The past due information is the primary credit quality indicator within the following classes of loans: (1) overdrafts in the commercial, financial and agricultural portfolio segment; (2) retail loans in the construction real estate portfolio segment; (3) mortgage loans, HELOC and installment loans in the residential real estate portfolio segment; and (4) consumer loans, GFSC loans, and check loans in the consumer portfolio segment. The primary credit indicator for commercial loans is based on an internal grading system that grades all commercial loans on a scale from 1 to 8. Credit grades are continuously monitored by the responsible loan officer and adjustments are made when appropriate. A grade of 1 indicates little or no credit risk and a grade of 8 is considered a loss. Commercial loans that are pass-rated (graded an 1 through a 4) are considered to be of acceptable credit risk. Commercial loans graded a 5 (special mention) are considered to be watch list credits and a higher PD is applied to these loans. Loans classified as special mention have potential weaknesses that require management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of Park’s credit position at some future date. Commercial loans graded a 6 (substandard), also considered watch list credits, are considered to represent higher credit risk and, as a result, a higher PD is applied to these loans. Loans classified as substandard are inadequately protected by the current sound worth and paying capacity of the obligor or the value of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that Park will sustain some loss if the deficiencies are not corrected. Commercial loans graded a 7 (doubtful) are shown as nonaccrual and Park generally charges these loans down to their fair value by taking a partial charge-off or recording a specific reserve. Loans classified as doubtful have all the weaknesses inherent in those classified as substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Certain 6-rated loans and all 7-rated loans are placed on nonaccrual status and included within the individually evaluated category. A loan is deemed impaired, and is individually evaluated, when management determines the borrower's ability to perform in accordance with the contractual loan agreement is in doubt. Any commercial loan graded an 8 (loss) is completely charged off. Based on the most recent analysis performed, the risk category of loans by class of loans as of December 31, 2022 and December 31, 2021 were as follows: December 31, 2022 Term Loans Amortized Cost Basis by Origination Year (In thousands) 2022 2021 2020 2019 2018 Prior Revolving Loans Amortized Cost Basis Total Commercial, financial and agricultural: Commercial, financial and agricultural (1) Risk rating Pass $ 197,497 $ 198,999 $ 142,487 $ 60,845 $ 32,887 $ 47,135 $ 546,237 $ 1,226,087 Special Mention 700 313 918 315 4 35 25,536 27,821 Substandard 1,101 18 2,737 226 1,836 8,424 26,464 40,806 Doubtful — — 3 77 80 172 192 524 Total $ 199,298 $ 199,330 $ 146,145 $ 61,463 $ 34,807 $ 55,766 $ 598,429 $ 1,295,238 Commercial, financial and agricultural: PPP Risk rating Pass $ — $ 1,875 $ 2,331 $ — $ — $ — $ — $ 4,206 Special Mention — — — — — — — — Substandard — — — — — — — — Doubtful — — — — — — — — Total $ — $ 1,875 $ 2,331 $ — $ — $ — $ — $ 4,206 Commercial real estate (1) Risk rating Pass $ 323,235 $ 374,763 $ 372,653 $ 220,072 $ 107,467 $ 305,539 $ 14,052 $ 1,717,781 Special Mention 199 3,256 3,388 5,863 16,059 22,220 150 51,135 Substandard 7,856 1,427 3,007 3,561 856 5,471 428 22,606 Doubtful — — — — 1,941 591 — 2,532 Total $ 331,290 $ 379,446 $ 379,048 $ 229,496 $ 126,323 $ 333,821 $ 14,630 $ 1,794,054 Construction real estate: Commercial Risk rating Pass $ 107,976 $ 40,534 $ 21,556 $ 2,686 $ 1,428 $ 3,015 $ 29,183 $ 206,378 Special Mention — — 232 — — — — 232 Substandard 652 800 260 — 660 — — 2,372 Doubtful — — — — — — — — Total $ 108,628 $ 41,334 $ 22,048 $ 2,686 $ 2,088 $ 3,015 $ 29,183 $ 208,982 Residential Real Estate: Commercial Risk rating Pass $ 107,086 $ 120,303 $ 147,802 $ 56,980 $ 33,140 $ 63,499 $ 15,191 $ 544,001 Special Mention — 92 1,477 440 — 1,625 — 3,634 Substandard 610 449 264 29 304 553 339 2,548 Doubtful — — — — — — — — Total $ 107,696 $ 120,844 $ 149,543 $ 57,449 $ 33,444 $ 65,677 $ 15,530 $ 550,183 Leases Risk rating Pass $ 7,629 $ 3,310 $ 3,347 $ 1,167 $ 981 $ 605 $ — $ 17,039 Special Mention 1,085 614 130 60 — — — 1,889 Substandard — — 464 111 12 26 — 613 Doubtful — — — 96 — — — 96 Total $ 8,714 $ 3,924 $ 3,941 $ 1,434 $ 993 $ 631 $ — $ 19,637 December 31, 2022 Term Loans Amortized Cost Basis by Origination Year (In thousands) 2022 2021 2020 2019 2018 Prior Revolving Loans Amortized Cost Basis Total Total Commercial Loans Risk rating Pass $ 743,423 $ 739,784 $ 690,176 $ 341,750 $ 175,903 $ 419,793 $ 604,663 $ 3,715,492 Special Mention 1,984 4,275 6,145 6,678 16,063 23,880 25,686 84,711 Substandard 10,219 2,694 6,732 3,927 3,668 14,474 27,231 68,945 Doubtful — — 3 173 2,021 763 192 3,152 Total $ 755,626 $ 746,753 $ 703,056 $ 352,528 $ 197,655 $ 458,910 $ 657,772 $ 3,872,300 (1) Included within each of commercial, financial and agricultural loans and commercial real estate loans is an immaterial amount of consumer loans that are not broken out by class.

These loans were recorded at the initial fair value of $272.8 million. NewDominion loans acquired with deteriorated credit quality (ASC 310-30) with a book value of $5.1 million were recorded at the initial fair value of $4.9 million. In conjunction with the Carolina Alliance acquisition, Park acquired loans and leases with a book value of $589.7 million as of the April 1, 2019 acquisition date. Carolina Alliance loans and leases were recorded at the initial fair value of $578.6 million. Loans and leases acquired with deteriorated credit quality (ASC 310-30) with a book value of $19.9 million were recorded at the initial fair value of $18.4 million. Upon adoption of CECL on January 1, 2021, $52,000 of the credit discount on PCD loans was reclassified to the allowance for credit losses. PCD loans are individually evaluated on a quarterly basis to determine if a specific reserve is necessary. At each of December 31, 2022 and December 31, 2021, there was no allowance for credit losses on PCD loans. The carrying amount of loans acquired with deteriorated credit quality at December 31, 2022 and December 31, 2021 was $4.7 million and $7.1 million, respectively. Troubled Debt Restructurings Management typically classifies loans as TDRs when a borrower is experiencing financial difficulties and Park has granted a concession to the borrower as part of a modification or in the loan renewal process. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of the borrower's debt in the foreseeable future without the modification. This evaluation is performed in accordance with the Company’s internal underwriting policy. Management’s policy is to modify loans by extending the term or by granting a temporary or permanent contractual interest rate below the market rate, not by forgiving debt. A court's discharge of a borrower's debt in a Chapter 7 bankruptcy is considered a concession when the borrower does not reaffirm the discharged debt. In response to the COVID-19 pandemic, Park worked with borrowers and provided modifications in the form of either interest only deferral or principal and interest deferral, in each case, for initial periods of up to 90 days. As necessary, Park made available a second 90-day interest only deferral or principal and interest deferral bringing the total potential deferral period to six months. Modifications were structured in a manner to best address each individual customer's then current situation. A majority of these modifications were excluded from the TDR classification under Section 4013 of the CARES Act or under applicable interagency guidance of the federal banking regulators. The modified loans were considered current and continued to accrue interest during the deferral period. Section 4013 of the CARES Act expired on December 31, 2021; therefore, modifications occurring after that date are subject to previous TDR classification guidance. As of December 31, 2022, there were no loans which were still within the COVID-19 deferral period. Certain loans which were modified during the years ended December 31, 2022 and 2021 did not meet the definition of a TDR as the modification was a delay in a payment that was considered to be insignificant. Management considers a forbearance period of up to three months or a delay in payment of up to 30 days to be insignificant. TDRs may be classified as accruing if the borrower has been current for a period of at least six months with respect to loan payments and management expects that the borrower will be able to continue to make payments in accordance with the terms of the restructured note. Management reviews all accruing TDRs quarterly to ensure payments continue to be made in accordance with the modified terms. There were $29.6 million of substandard commercial loans modified during the year ended December 31, 2022 that did not meet the definition of a TDR. Excluding COVID-19 related modifications, there were $0.2 million of substandard commercial loans modified during the year ended December 31, 2021 that did not meet the definition of a TDR. Consumer loans modified during 2022, which did not meet the definition of a TDR, had a total amortized cost at December 31, 2022 of $41.7 million. Excluding COVID-19 related modifications, consumer loans modified during 2021, which did not meet the definition of a TDR, had a total amortized cost at December 31, 2021 of $32.9 million. Many of these loans were to borrowers who were not experiencing financial difficulties but who were looking to reduce their cost of funds. At December 31, 2022 and 2021, there were $17.5 million and $20.9 million, respectively, of TDRs included in the nonaccrual loan totals. At December 31, 2022 and 2021, $7.5 million and $10.5 million, respectively, of these nonaccrual TDRs were performing in accordance with the terms of the restructured notes. At December 31, 2022 and 2021, loans totaling $20.1 million and $28.3 million, respectively, were included in accruing TDR loan totals. Management will continue to review the restructured loans and may determine it is appropriate to move certain nonaccrual TDRs to accrual status in the future. At December 31, 2022 and 2021, Park had commitments to lend $1.6 million and $3.0 million, respectively, of additional funds to borrowers whose outstanding loan terms had been modified in a TDR. At December 31, 2022 and 2021, there were $2.2 million and $0.3 million, respectively, of specific reserves related to TDRs. Modifications made in 2022 and 2021 were largely the result of renewals and extending the maturity date of the loans at terms consistent with the original notes. These modifications were deemed to be TDRs primarily due to Park’s conclusion that the borrower would likely not have qualified for similar terms through another lender. Many of the modifications deemed to be TDRs were previously identified as individually evaluated loans, and thus were also previously evaluated for impairment under ASC 310. Additional specific reserves of $0.9 million were recorded during the year ended December 31, 2022, as a result of TDRs identified in the 2022 year. Additional specific reserves of $0.2 million were recorded during the year ended December 31, 2021, as a result of TDRs identified in the 2021 year. Additional specific reserves of $7,000 were recorded during the year ended December 31, 2020, as a result of TDRs identified in the 2020 year. Quarterly, management reviews renewals/modifications of loans previously identified as TDRs to consider if it is appropriate to remove the TDR classification. If the borrower is no longer experiencing financial difficulty and the renewal/modification did not contain a concessionary interest rate or other concessionary terms and the terms of the renewal/modification are considered to be market terms based on the current risk characteristics of the borrower, management considers the potential removal of the TDR classification. If deemed appropriate, the TDR classification is removed if the borrower has complied with the terms of the loan at the date of the renewal/modification and there was a reasonable expectation that the borrower will continue to comply with the terms of the loan subsequent to the date of the renewal/modification. The majority of these TDRs were originally considered restructurings in a prior year as a result of a renewal/modification with an interest rate that was not commensurate with the risk of the underlying loan at the time of the renewal/modification. During the years ended December 31, 2022 and 2021, Park removed the TDR classification on $1.0 million and $4.1 million, respectively, of loans that met the requirements discussed above. The following tables detail the number of contracts modified as TDRs during the years ended December 31, 2022, 2021 and 2020 as well as the amortized cost/ recorded investment of these contracts at December 31, 2022, 2021, and 2020. The amortized cost/ recorded investment pre- and post-modification is generally the same due to the fact that Park does not typically forgive principal.

Allowance for Loan Losses

Allowance for Loan Losses	12 Months Ended
	Dec. 31, 2022
Financing Receivable, Allowance for Credit Loss, Writeoff, after Recovery [Abstract]
Allowance for Credit Losses [Text Block]	Allowance for Credit LossesThe ACL is an estimate of the expected credit losses on financial assets measured at amortized cost, which is measured using relevant information about past events, including historical credit loss experience on financial assets with similar risk characteristics, current conditions, and reasonable and supportable forecasts that affect the collectability of the remaining cash flows over the contractual term of the financial assets. A provision for credit losses is charged to operations based on management’s periodic evaluation of these and other pertinent factors as discussed within Note 1-Summary of Significant Accounting Policies. During the first quarter of 2021, Park adopted ASU 2016-13, including the CECL methodology for estimating the ACL. This standard was adopted prospectively on January 1, 2021, resulting in a $6.1 million increase to the ACL and a $3.9 million increase to the allowance for unfunded credit losses. A cumulative effect adjustment resulting in an $8.0 million decrease to retained earnings and a $2.1 million increase to deferred tax assets was also recorded as of the adoption of ASU 2016-13. Quantitative Considerations The ACL is primarily calculated utilizing a DCF model. Key inputs and assumptions used in this model are discussed below: • Forecast model - For each portfolio segment, a LDA was performed in order to identify appropriate loss drivers and create a regression model for use in forecasting cash flows. The LDA analysis utilized Park's own FFIEC Call Report data for the commercial, financial and agricultural and residential real estate portfolio segments. Peer data was incorporated into the analysis for the commercial real estate, construction real estate, and consumer portfolio segments. Park updated the LDA in the fourth quarter of 2022 with data through September 30, 2022. After considering the impact of the inclusion of periods impacted by COVID, as well as analysis of the ongoing applicability of the selected peer group, management decided it was appropriate to continue to utilize the LDA analysis from the fourth quarter of 2019 as the correlation of the LDA was higher. • Probability of default – PD is the probability that an asset will be in default within a given time frame. Park has defined default to be when a charge-off has occurred, a loan is placed on nonaccrual, or a loan is greater than 90 days past due. Whenever possible, Park utilizes its own loan-level PDs for the reasonable and supportable forecast period. When loan-level data is not available reflecting the forecasted economic conditions, a forecast model is utilized to estimate PDs. • Loss given default – LGD is the percentage of the asset not expected to be collected due to default. Whenever possible, Park utilizes its own loan-level LGDs for the reasonable and supportable forecast period. When it is not possible to use Park's own LGDs, the LGD is derived using a method referred to as Frye Jacobs. • Prepayments and curtailments – Prepayments and curtailments are calculated based on Park’s own data utilizing a three-year average. This analysis is updated annually in the fourth quarter and was last updated in the fourth quarter of 2022. • Forecast and reversion – Park has established a one-year reasonable and supportable forecast period with a one-year straight line reversion to the long-term historical average. • Economic forecast - Park utilizes a third party to provide economic forecasts under various scenarios, which are weighted in order to reflect model risk in the current economic environment. The scenario weighting is evaluated by management on a quarterly basis. ◦ As of December 31, 2021, the "most likely" scenario forecasted Ohio unemployment to decrease, to a range between 3.32% and 3.97%, during the next four quarters. In determining the appropriate weighting of scenarios at December 31, 2021, management considered the range of forecasted unemployment as well as a number of economic indicators. While some economic indications appeared to be optimistic, the Omicron variant, rising inflation, volatility in consumer confidence, employment, supply chain and workforce challenges continued to cause uncertainty to the overall economic environment. Considering these factors, management determined it was appropriate to weigh the "most likely" scenario 50% and the "moderate recession" scenario 50% at December 31, 2021. ◦ A s of December 31, 2022, the "most likely" scenario forecasted Ohio unemployment between 4.14% and 4.36% during the next four quarters. In determining the appropriate weighting of scenarios at December 31, 2022, management considered the range of forecasted unemployment as well as a number of economic indicators. The continued high levels of inflation, historically low consumer confidence, rising interest rates, geopolitical conflict (including the conflict between Russia and Ukraine), and workforce and supply chain challenges continued to cause uncertainty to the overall economic environment. Considering these factors, management determined it was appropriate to maintain the existing weighting, and weigh the "most likely" scenario 50% and the "moderate recession" scenario 50% at December 31, 20 22. Deteriorating forecasts, largely in the "moderate recession" scenario, resulted in a 10 basis point increase in the weighted quantitative allowance from December 31, 2021. Qualitative Considerations Park reviews various internal and external factors to consider the need for any qualitative adjustments to the quantitative model. Factors considered include the following : • The nature and volume of Park’s financial assets; the existence, growth, and effect of any concentrations of credit and the volume and severity of past due financial assets, the volume of nonaccrual assets, and the volume and severity of adversely classified or graded assets. Specifically, management considers: ◦ Trends (e.g., growth, reduction) in specific categories of the loan portfolio, as well as adjustments to the types of loans offered by Park. ◦ Level of and trend in loan delinquencies, troubled loans, commercial watch list loans and nonperforming loans. ◦ Level of and trend in new nonaccrual loans. ◦ Level of and trend in loan charge-offs and recoveries. • Park's lending policies and procedures, including changes in lending strategies, underwriting standards and practices for collections, write-offs, and recoveries. • The quality of Park’s credit review function. • The experience, ability, and depth of Park’s lending, investment, collection, and other relevant management and staff. • The effect of other external factors such as the regulatory, legal and technological environments; competition; geopolitical conflict; and events such as natural disasters or pandemics. • Actual and expected changes in international, national, regional, and local economic and business conditions and developments in the markets in which Park operates that affect the collectibility of financial assets. • Where the U.S. economy is within a given credit cycle. • The extent that there is government assistance (stimulus). During 2020, Park added an additional reserve for three industries at particularly high risk due to the COVID-19 pandemic: hotels and accommodations; restaurants and food service; and strip shopping centers. These industries experienced high levels of deferrals and had been particularly impacted by shut downs of non-essential businesses, increased health department regulations, and changes in consumer behavior. Management expected that a relatively higher percentage of the 4-rated credits in these portfolios would eventually migrate to special mention, substandard, or individually evaluated status. In adopting CECL, management determined it was appropriate to retain this qualitative adjustment as this adjustment took into account the additional risk in these portfolios, which was not captured in the quantitative calculation. As COVID cases began to decline during the first quarter of 2022, travel increased, restrictions lifted, and consumers began increasing restaurant visits and shopping in person and these industries began to show signs of recovery. Beginning in the first quarter of 2022, management began decreasing these reserves 25% each quarter to take into account improvements in these industry sectors. In the fourth quarter 2022, these industries continued to show positive trends and COVID-19 has become less impactful to day-to-day life. Therefore, management deemed it appropriate to reduce the factors the remaining 25%, taking this qualitative adjustment to zero. A breakout of the 4-rated balances within these portfolios and the additional reserve related to these portfolios, as of December 31, 2021, is detailed in the following table: December 31, 2021 (In thousands) 4-Rated Balance Additional Reserve Hotels and accommodations $ 148,018 $ 2,226 Restaurants and food service 40,648 917 Strip shopping centers 184,171 2,033 Total $ 372,837 $ 5,176 Additionally, at December 31, 2021, management applied a 1.00% reserve to all hotels and accommodations loans in the collectively evaluated population to account for increased valuation risk. At December 31, 2021, Park's collectively evaluated hotels and accommodation loans had a balance of $203.9 million with an additional reserve related to valuation risks of $2.0 million. With improvement in occupancy and revenue in Park's hotel and accommodations portfolio, management concluded it appropriate to decrease the hotel and accommodations valuation reserve to zero at December 31, 2022. At December 31, 2022 and 2021, Park had $4.2 million and $74.4 million, respectively, of PPP loans which were included in the commercial, financial and agricultural portfolio segment. These loans are guaranteed by the SBA and thus have not been reserved for using the same methodology as the rest of Park’s loan portfolio. A 10 basis point reserve was calculated for these loans to reflect minimal credit risk at December 31, 2022 and December 31, 2021.

Long-Term Debt, Unclassified [Abstract]
Subordinated Debentures/Notes	Subordinated Notes As part of the acquisition of Vision's parent bank holding company ("Vision Parent") on March 9, 2007, Park became the successor to Vision Parent under (i) the Amended and Restated Trust Agreement of Vision Bancshares Trust I (the “Trust”), dated as of December 5, 2005, (ii) the Junior Subordinated Indenture, dated as of December 5, 2005, and (iii) the Guarantee Agreement, also dated as of December 5, 2005. On December 1, 2005, Vision Parent formed a wholly-owned Delaware statutory business trust, Vision Bancshares Trust I (“Trust I”), which issued $15.0 million of Trust I's floating rate preferred securities (the “Trust Preferred Securities”) to institutional investors. These Trust Preferred Securities qualify as Tier I capital under FRB guidelines. All of the common securities of Trust I are owned by Park. The proceeds from the issuance of the common securities and the Trust Preferred Securities were used by Trust I to purchase $15.5 million of junior subordinated notes, which carry a floating rate based on three-month LIBOR plus 148 basis points. The junior subordinated notes represent the sole asset of Trust I. The Trust Preferred Securities accrue and pay distributions at a floating rate of three-month LIBOR plus 148 basis points per annum. The Trust Preferred Securities are mandatorily redeemable upon maturity of the junior subordinated notes in December 2035, or upon earlier redemption as provided in the junior subordinated notes. Since December 30, 2010, Park has had the right to redeem the junior subordinated notes purchased by Trust I in whole or in part. As specified in the indenture, if the junior subordinated notes are redeemed prior to maturity, the redemption price will be the principal amount, plus any unpaid accrued interest. In accordance with U.S. GAAP, Trust I is not consolidated with Park’s financial statements, but rather the subordinated notes are reflected as a liability. On August 20, 2020, Park completed the issuance and sale of $175 million aggregate principal amount of its 4.50% Fixed-to-Floating Rate Subordinated Notes due 2030 (the "Subordinated Notes"). The Subordinated Notes initially bear a fixed interest rate of 4.50% per year, payable semi-annually in arrears on March 1 and September 1 of each year, commencing on March 1, 2021. Commencing on September 1, 2025, the Subordinated Notes will bear interest at a floating rate per annum equal to the Benchmark rate, which is expected to be Three-Month Term SOFR, plus a spread of 439 basis points for each quarterly interest period during the floating rate period, payable quarterly in arrears; provided, however, that if the Benchmark rate is less than zero, then the Benchmark rate will be deemed to be zero. The Company may, at its option, beginning with the interest payment date of September 1, 2025 and on any interest payment date thereafter, redeem the Subordinated Notes, in whole or in part, from time to time, subject to obtaining the prior approval of the holders of the Company’s senior indebtedness and of the Federal Reserve Board to the extent the approval of the Federal Reserve Board is then required under the capital adequacy rules of the Federal Reserve Board, at a redemption price equal to 100% of the principal amount of the Subordinated Notes being redeemed, plus accrued and unpaid interest thereon to but excluding the date of redemption. The issuance costs of the Subordinated Notes totaled $2.4 million, which amount is being amortized through the Subordinated Note call date. At December 31, 2022 and 2021, the Subordinated Notes, net of unamortized issuance costs, totaled $173.7 million and $173.2 million, and qualify as Tier 2 capital for Park under the Federal Reserve Board capital adequacy rules.

The amount exchanged is determined by reference to the notional amount and the other terms of the individual interest rate swap agreements. Borrowing Derivatives : At December 31, 2022, Park had no borrowing derivatives. Interest rate swaps with notional amounts totaling $25.0 million at December 31, 2021 were designated as cash flow hedges of certain FHLB advances. Loan Derivatives : In conjunction with the Carolina Alliance acquisition, Park acquired interest rate swaps related to certain commercial loans. Simultaneously with borrowers entering into interest rate swaps, Carolina Alliance entered into offsetting interest rate swaps executed with a third party, such that Carolina Alliance minimized its net interest rate risk exposure resulting from such transactions. These interest rate swaps had a notional amount totaling $21.7 million and $29.7 million at December 31, 2022 and December 31, 2021, respectively. All of the Company's interest rate swaps were determined to be fully effective during the years ended December 31, 2022 and 2021 . As such, no amount of ineffectiveness has been included in net income. Therefore, the aggregate fair value of the swaps is recorded in "Other assets" and "Other liabilities" with changes in fair value recorded in "Other comprehensive (loss) income". The amount included in "Accumulated other comprehensive (loss) income, net of tax" would be reclassified to net income should the hedges no longer be considered effective. During the year ended December 31, 2022, Park recognized expense of $66,000 as the result of the early termination of a borrowing interest rate swap. No expense related to early termination was recognized during the years ended December 31, 2021 and 2020, respectively . Park expects the outstanding hedges to remain fully effective during the remaining respective terms of the swaps. Summary information about Park's interest rate swaps as of December 31, 2022 and December 31, 2021 was as follows: December 31, 2022 December 31, 2021 (In thousands, except weighted average data) Borrowing Derivatives Loan Derivatives Borrowing Derivatives Loan Derivatives Notional amounts $ — $ 21,700 $ 25,000 $ 29,651 Weighted average pay rates — % 4.553 % 2.595 % 4.668 % Weighted average receive rates — % 4.553 % 0.124 % 4.668 % Weighted average maturity (years) 0.0 7.9 0.5 8.2 Unrealized losses $ — $ — $ 262 $ — Interest expense recorded on swap transactions was $171,000, $614,000 and $423,000 for the years ended December 31, 2022, 2021, and 2020, respectively.

In order to hedge the change in interest rates resulting from its commitments to fund the loans, the Company enters into forward commitments for the future delivery of mortgage loans when interest rate locks are entered into. These mortgage banking derivatives are not designated as hedge relationships. The fair value of an interest rate lock is recorded at the time the commitment to fund the mortgage loan is executed and is adjusted for the expected exercise of the commitment before the loan is funded. Fair values of these mortgage banking derivatives are estimated based on changes in mortgage interest rates from the date the interest on the loan is locked. Changes in the fair values of these derivatives are included in "Other service income" in the Consolidated Statements of Income. At December 31, 2022 and December 31, 2021 , Park had $2.1 million and $13.3 million, respectively, of interest rate lock commitments. The fair value of these mortgage banking derivatives was reflected by a derivative asset of $46,000 and $0.3 million at December 31, 2022 and December 31, 2021 , respectively. Other Derivatives In connection with the sale of Park’s Class B Visa shares during 2009, Park entered into a swap agreement with the purchaser of the shares. The swap agreement adjusts for dilution in the conversion ratio of Class B Visa shares resulting from certain Visa litigation. At December 31, 2022 and 2021, the fair value of the swap liability of $243,000 and $226,000, respectively, represented an estimate of the exposure based upon probability-weighted potential Visa litigation losses.

Defined Benefit Plans and Other Postretirement Benefit Plans Disclosures [Abstract]
Benefit Plans	Benefit Plans The Corporation has a noncontributory Defined Benefit Pension Plan (the “Pension Plan”) covering substantially all of the employees of Park National Corporation and its subsidiaries. The Pension Plan provides benefits based on an employee’s years of service and compensation. There was no pension contribution in 2022 or 2021 and no contribution is expected to be made in 2023. Using accrual measurement dates of December 31, 2022 and 2021, plan assets and benefit obligation activity for the Pension Plan are listed below: (In thousands) 2022 2021 Change in fair value of plan assets Fair value at beginning of measurement period $ 263,473 $ 230,442 Actual return on plan assets (37,319) 48,138 Benefits paid (17,016) (15,107) Fair value at end of measurement period $ 209,138 $ 263,473 Change in benefit obligation Projected benefit obligation at beginning of measurement period $ 182,964 $ 184,410 Service cost 9,749 9,916 Interest cost 5,705 5,359 Plan amendments 558 — Actuarial loss (54,566) (1,614) Benefits paid (17,016) (15,107) Projected benefit obligation at the end of measurement period $ 127,394 $ 182,964 Funded status at end of year (fair value of plan assets less benefit obligation) $ 81,744 $ 80,509 The decrease in the projected benefit obligation ("PBO") from $183.0 million as of December 31, 2021 to $127.4 million as of December 31, 2022, was the result of an increase in the discount rate from 3.23% to 5.32% and assumption updates for IRS mortality tables, partially offset by demographic losses driven by termination experience, salary increases greater than assumed, and the impact of plan amendments. The asset allocation for the Pension Plan as of each measurement date, by asset category, was as follows: Percentage of Plan Assets Asset category Target Allocation 2022 2021 Equity securities 50% - 100% 84 % 82 % Fixed income and cash equivalents remaining balance 16 % 18 % Total 100 % 100 % The investment policy, as established by the Retirement Plan Committee, is to invest assets according to the target allocation stated above. Assets will be reallocated periodically based on the investment strategy of the Retirement Plan Committee. The investment policy is reviewed periodically. The expected long-term rate of return on plan assets used to measure the benefit obligation was 6.92% at both December 31, 2022 and December 31, 2021. This return was based on the expected long-term return of each of the asset categories, weighted based on the median of the target allocation for each class. The accumulated benefit obligation for the Pension Plan was $106.3 million and $146.2 million at December 31, 2022 and 2021, respectively. On November 17, 2009, the Park Pension Plan completed the purchase of 115,800 common shares of Park for $7.0 million or $60.45 per share. At December 31, 2022 and 2021, the fair value of the 115,800 common shares held by the Pension Plan was $16.3 million, or $140.75 per share and $15.9 million, or $137.31 per share, respectively.

The fair values of equity securities, consisting of mutual fund investments and common stock held by the Pension Plan, are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs). Additionally, due to their short-term nature, the fair value of interest bearing demand deposits is determined by reference to their face value (Level 1 inputs). Interest bearing time deposits, United States Government agency obligations and corporate bonds are valued by the trustee based on yields available on comparable securities of issuers with similar credit ratings as of the end of the year (Level 2 inputs). No investments were categorized as Level 3 inputs. The fair value of the plan assets at December 31, 2022 and December 31, 2021, by asset class, is as follows.

Risks and Uncertainties [Abstract]
Financial Instruments with Off-Balance Sheet Risk and Financial Instruments with Concentration of Credit Risk	Financial Instruments with Off-Balance Sheet Risk and Financial Instruments with Concentrations of Credit Risk The Corporation is party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include loan commitments and standby letters of credit. The financial instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the Consolidated Financial Statements. The Corporation’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for loan commitments and standby letters of credit is represented by the contractual amount of those financial instruments. The Corporation uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. Since many of the loan commitments may expire without being drawn upon, the total commitment amount does not necessarily represent future cash requirements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan commitments to customers. The total amounts of off-balance sheet financial instruments with credit risk were as follows: December 31 (In thousands) 2022 2021 Loan commitments $ 1,416,699 $ 1,364,224 Standby letters of credit 30,468 18,216 The loan commitments are generally for variable rates of interest. The Corporation grants retail, commercial and commercial real estate loans to customers primarily located in Ohio, Kentucky, North Carolina and South Carolina with the exception of nationwide aircraft loans and nationwide asset-based lending to consumer finance companies. The Corporation evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Corporation upon the extension of credit, is based on management’s credit evaluation of the customer. Collateral held varies but may include accounts receivable, inventory, property, plant and equipment, and real estate. Although the Corporation has a diversified loan portfolio, a substantial portion of the borrowers’ ability to honor their contracts is dependent upon the economic conditions of the borrowers' respective geographic locations and industries.

Transfers and Servicing of Financial Assets [Abstract]
Loan Servicing	Loan Servicing Park serviced sold mortgage loans of $2,051 million at December 31, 2022, compared to $2,132 million at December 31, 2021 and $1,972 million at December 31, 2020. At December 31, 2022, $3.2 million of the sold mortgage loans were sold with recourse compared to $3.3 million at December 31, 2021 and $1.7 million at December 31, 2020. Management closely monitors the delinquency rates on the mortgage loans sold with recourse. As of December 31, 2022 and 2021, management had established a reserve of $59,000 and $57,000, respectively, to account for future loan repurchases. When Park sells mortgage loans with servicing rights retained, servicing rights are initially recorded at fair value. Park selected the “amortization method” as permissible within U.S. GAAP, whereby the servicing rights capitalized are amortized in proportion to and over the period of estimated future servicing income of the underlying loan. At the end of each reporting period, the carrying value of MSRs is assessed for impairment with a comparison to fair value. MSRs are carried at the lower of their amortized cost or fair value. The amortization of MSRs is included within "Other service income" in the Consolidated Statements of Income. Activity for MSRs and the related valuation allowance follows: December 31 (In thousands) 2022 2021 2020 MSRs: Carrying amount, net, beginning of year $ 15,264 $ 12,210 $ 10,070 Additions 1,455 4,945 8,627 Amortization (2,313) (3,512) (4,123) Change in valuation allowance 1,386 1,621 (2,364) Carrying amount, net, end of year $ 15,792 $ 15,264 $ 12,210 Valuation allowance: Beginning of year $ 1,568 $ 3,189 $ 825 Change in valuation allowance (1,386) (1,621) 2,364 End of year $ 182 $ 1,568 $ 3,189 The fair value of MSRs was $17.4 million and $15.3 million at December 31, 2022 and 2021, respectively. The fair value of MSRs at December 31, 2022 was established using a discount rate of 12% and constant prepayment speeds ranging from 6.96% to 19.14%. The fair value of MSRs at December 31, 2021 was established using a discount rate of 12% and constant prepayment speeds ranging from 11.10% to 27.90%. Servicing fees included in "Other service income" were $5.4 million, $5.3 million and $4.1 million for the years ended December 31, 2022, 2021 and 2020, respectively.

Leases [Abstract]
Lessee, Operating Leases	Leases Park is a lessee in several noncancellable operating lease arrangements, primarily for retail branches, administrative and warehouse buildings, ATMs, and certain office equipment within its Ohio, North Carolina, South Carolina, and Kentucky markets. Certain of these leases contain renewal options for periods ranging from one to five years. Park’s leases generally do not include termination options for either party to the lease or restrictive financial or other covenants. Payments due under the lease arrangements include fixed payments plus, for many of Park’s real estate leases, variable payments such as Park's proportionate share of property taxes, insurance and common area maintenance. Park's operating lease ROU asset and lease liability are presented in “Operating lease right-of-use asset" and "Operating lease liability," respectively, on Park's Consolidated Balance Sheets. The carrying amounts of Park's ROU asset and lease liability at December 31, 2022 were $17.6 million and $19.3 million, respectively. At December 31, 2021, the carrying amounts of Park's ROU assets and lease liability were $13.4 million and $14.3 million, respectively. Park's operating lease expense is recorded in "Occupancy expense" on the Company's Consolidated Statements of Income. Other information related to operating leases for the years ended December 31, 2022, 2021 and 2020 follows: (In thousands) Year ended December 31, 2022 Year ended December 31, 2021 Year ended December 31, 2020 Lease cost Operating lease cost $ 3,073 $ 2,827 $ 3,463 Sublease income (252) (253) (352) Total lease cost $ 2,821 $ 2,574 $ 3,111 Other information Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 3,116 $ 3,199 $ 3,553 ROU assets obtained in exchange for new operating lease liabilities $ 7,867 $ 1,190 $ 7,821 Reductions to ROU assets resulting from reductions to lease obligations $ (2,812) $ (2,865) $ (3,084) Park's operating leases had a weighted average remaining term of 10.0 years and 6.8 years at December 31, 2022 and 2021, respectively.

Fair Value Disclosures [Abstract]
Fair Values	Fair Value The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three levels of inputs that Park uses to measure fair value are as follows: • Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that Park has the ability to access as of the measurement date. • Level 2: Level 1 inputs for assets or liabilities that are not actively traded. Also consists of an observable market price for a similar asset or liability. This includes the use of “matrix pricing” to value debt securities absent the exclusive use of quoted prices. • Level 3: Consists of unobservable inputs that are used to measure fair value when observable market inputs are not available. This could include the use of internally developed models, financial forecasting and similar inputs. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the balance sheet date. When possible, the Company looks to active and observable markets to price identical assets or liabilities. When identical assets and liabilities are not traded in active markets, the Company looks to observable market data for similar assets and liabilities. However, certain assets and liabilities are not traded in observable markets and Park must use other valuation methods to develop a fair value. The fair value of individually evaluated collateral dependent loans is typically based on the fair value of the underlying collateral, which is estimated through third-party appraisals in accordance with Park's valuation requirements under its commercial and real estate loan policies. Assets and Liabilities Measured at Fair Value on a Recurring Basis : The following table presents assets and liabilities measured at fair value on a recurring basis: Fair Value Measurements at December 31, 2022 using: (In thousands) Level 1 Level 2 Level 3 Balance at December 31, 2022 Assets Investment securities: Obligations of U.S. Government sponsored entities $ — $ 37,213 $ — $ 37,213 Obligations of states and political subdivisions — 406,711 — 406,711 U.S. Government sponsored entities’ asset-backed securities — 756,761 — 756,761 Collateralized loan obligations — 516,539 — 516,539 Corporate debt securities — 9,472 7,000 16,472 Equity securities 1,420 — 439 1,859 Mortgage loans held for sale — 2,149 — 2,149 Mortgage IRLCs — 46 — 46 Loan interest rate swaps — 1,508 — 1,508 Liabilities Fair value swap $ — $ — $ 243 $ 243 Loan interest rate swaps — 1,508 — 1,508 Fair Value Measurements at December 31, 2021 using: (In thousands) Level 1 Level 2 Level 3 Balance at December 31, 2021 Assets Investment securities: Obligations of states and political subdivisions $ — $ 389,591 $ — $ 389,591 U.S. Government sponsored entities’ asset-backed securities — 854,463 — 854,463 Collateralized loan obligations — 498,674 — 498,674 Corporate debt securities — 11,412 — 11,412 Equity securities 1,630 — 499 2,129 Mortgage loans held for sale — 9,387 — 9,387 Mortgage IRLCs — 333 — 333 Loan interest rate swaps — 1,952 — 1,952 Liabilities Fair value swap $ — $ — $ 226 $ 226 Borrowing interest rate swap — 262 — 262 Loan interest rate swaps — 1,952 — 1,952 The following methods and assumptions were used by the Company in determining the fair value of the financial assets and liabilities discussed above: Interest rate swaps: The fair values of interest rate swaps are based on valuation models using observable market data as of the measurement date (Level 2). Investment securities: Fair values for investment securities are based on quoted market prices, where available (Level 1). If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments (Level 2). For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows (Level 3). Fair value swap: The fair value of the swap agreement entered into with the purchaser of the Visa Class B shares represents an internally developed estimate of the exposure based upon probability-weighted potential Visa litigation losses and is classified as Level 3. Mortgage interest rate lock commitments: Mortgage IRLCs are based on current secondary market pricing and are classified as Level 2. Mortgage loans held for sale: Mortgage loans held for sale are carried at their fair value. Mortgage loans held for sale are estimated using market prices for similar product types and, therefore, are classified in Level 2. The following tables present a reconciliation of the beginning and ending balances of the Level 3 inputs for the years ended December 31, 2022 and 2021, for financial instruments measured on a recurring basis and classified as Level 3: Level 3 Fair Value Measurements (In thousands) Corporate debt securities Equity securities Fair value swap Balance at January 1, 2022 $ — $ 499 $ (226) Total Losses Included in other income / expense — (60) (221) Transfers into level 3 7,000 — — Purchases, sales, issuances and settlements, other, net — — 204 Balance at December 31, 2022 $ 7,000 $ 439 $ (243) Balance at January 1, 2021 $ — $ 485 $ (226) Total Gains Included in other income — 14 — Balance at December 31, 2021 $ — $ 499 $ (226) Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis: The following methods and assumptions were used by the Company in determining the fair value of assets and liabilities measured at fair value on a nonrecurring basis as described below: Individually evaluated collateral dependent loans: When a loan is individually evaluated, it is valued at the lower of cost or fair value. Collateral dependent loans which are individually evaluated and carried at fair value have been partially charged off or receive specific allocations of the allowance for credit losses. For collateral dependent loans, fair value is generally based on real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including the comparable sales approach and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments result in a Level 3 classification of the inputs for determining fair value. Collateral is then adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and the client’s business, resulting in a Level 3 fair value classification. Individually evaluated loans are evaluated on a quarterly basis for additional impairment and adjusted accordingly. Additionally, updated independent valuations are obtained annually for all collateral dependent loans in accordance with Company policy. OREO: Assets acquired through or in lieu of loan foreclosure are initially recorded at fair value less costs to sell when acquired. The carrying value of OREO is not re-measured to fair value on a recurring basis, but is subject to fair value adjustments when the carrying value exceeds the fair value, less estimated selling costs. Fair value is based on recent real estate appraisals and is updated at least annually. These appraisals may utilize a single valuation approach or a combination of approaches including the comparable sales approach and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments result in a Level 3 classification of the inputs for determining fair value. Appraisals for both individually evaluated collateral dependent loans and OREO are performed by licensed appraisers. Appraisals are generally obtained to support the fair value of collateral. In general, there are three types of appraisals received by the Company: real estate appraisals, income approach appraisals, and lot development loan appraisals. These are discussed below: • Real estate appraisals typically incorporate measures such as recent sales prices for comparable properties. Appraisers may make adjustments to the sales prices of the comparable properties as deemed appropriate based on the age, condition or general characteristics of the subject property. Management generally applies a 15% discount to real estate appraised values which management expects will cover all disposition costs (including selling costs). This 15% discount is based on historical discounts to appraised values on sold OREO properties. • Income approach appraisals typically incorporate the annual net operating income of the business divided by an appropriate capitalization rate, as determined by the appraiser. Management generally applies a 15% discount to income approach appraised values which management expects will cover all disposition costs (including selling costs). • Lot development loan appraisals are typically performed using a discounted cash flow analysis. Appraisers determine an anticipated absorption period and a discount rate that takes into account an investor’s required rate of return based on recent comparable sales. Management generally applies a 6% discount to lot development appraised values, which is an additional discount above the net present value calculation included in the appraisal, to account for selling costs. Other repossessed assets: Other repossessed assets are initially recorded at fair value less costs to sell when acquired. The carrying value of other repossessed assets is not re-measured to fair value on a recurring basis, but is subject to fair value adjustments when the carrying value exceeds the fair value, less estimated selling costs. At December 31, 2021, other repossessed assets primarily consisted of aircraft acquired as part of a loan workout. Fair value was based on Aircraft Bluebook and VREF Aircraft Value Reference values based on the model of aircraft and adjustments for flight hours, features and other variables. Such adjustments resulted in a Level 3 classification of the inputs for determining fair value. There were no repossessed assets carried at fair value at December 31, 2022. MSRs: MSRs are carried at the lower of cost or fair value. MSRs do not trade in active, open markets with readily observable prices. For example, sales of MSRs do occur, but precise terms and conditions typically are not readily available. As such, management, with the assistance of a third-party specialist, determines fair value based on the discounted value of the future cash flows estimated to be received. Significant inputs include the discount rate and assumed prepayment speeds. The calculated fair value is then compared to market values where possible to ascertain the reasonableness of the valuation in relation to current market expectations for similar products. Accordingly, MSRs are classified as Level 2. The following tables present assets and liabilities measured at fair value on a nonrecurring basis. Individually evaluated collateral dependent loans secured by real estate are carried at fair value if they have been charged down to fair value or if a specific valuation allowance has been established. As of December 31, 2022 and 2021, there were no PCD loans carried at fair value. A new cost basis is established at the time a property is initially recorded in OREO. OREO properties are carried at fair value if a devaluation has been taken with respect to the property's value subsequent to the initial measurement.

Banking Regulation, Total Capital [Abstract]
Capital Ratios	Capital RatiosFinancial institution regulators have established guidelines for minimum capital ratios for banks, thrifts and bank holding companies. Park has elected not to include the net unrealized gain or loss on debt securities AFS in computing regulatory capital. Park has adopted the Basel III regulatory capital framework as approved by the federal banking agencies. Under the Basel III regulatory capital framework, in order to avoid limitations on capital distributions, including dividend payments and stock repurchases, and certain discretionary bonus payments to executive officers, Park must hold a capital conservation buffer of 2.50% above the adequately capitalized risk-based capital ratios. The amounts shown below as the adequately capitalized ratio plus capital conservation buffer include the 2.50% buffer. The Federal Reserve Board has also adopted requirements Park must maintain to be deemed "well-capitalized" and to remain a financial holding company. Each of PNB and Park met all of the well-capitalized ratio guidelines applicable to it at December 31, 2022. The following table indicates the capital ratios for PNB and Park at December 31, 2022 and 2021.

(3) "Miscellaneous" income includes brokerage income, safe deposit box rentals, and miscellaneous bank fees totaling $7.3 million, all of which are within the scope of ASC 606. A description of Park's material revenue streams accounted for under ASC 606 follows: Income from fiduciary activities (gross) : Park earns fiduciary fee income and investment brokerage fees from its contracts with trust customers for various fiduciary and investment-related services. These fees are earned over time as the Company provides the contracted monthly and quarterly services and are generally assessed based on the market value of the trust assets. Service charges on deposit accounts and ATM fees : The Corporation earns fees from the Corporation's deposit customers for transaction-based, account maintenance, and overdraft services. Transaction-based fees, which include services such as ATM use fees, stop payment charges, statement rendering fees, and ACH fees, are recognized at the time the transaction is executed as that is the point in time the Corporation fulfills the customer's request. Account maintenance fees, which relate primarily to monthly maintenance, are generally recognized at the end of the month, representing the period over which the Corporation satisfies the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are withdrawn from the customer's account balance. Other service income : Other service income includes income from (1) the sale and servicing of loans sold to the secondary market, (2) incentive income from third-party credit card issuers, and (3) loan customers for various loan-related activities and services. Income related to the sale and servicing of loans sold to the secondary market is included within "Other service income", but is not within the scope of ASC 606. Services that fall within the scope of ASC 606 are recognized as revenue when the Company satisfies the Company's performance obligation to the customer. Debit card fee income : Park earns interchange fees from debit cardholder transactions conducted primarily through the Visa payment network. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, net of card network fees, concurrently with the transaction processing services provided to the cardholder. Gain or loss on sale of OREO, net : The Corporation 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 delivery of an executed deed. When Park finances the sale of OREO to the buyer, the Corporation assesses whether the buyer is committed to perform the buyer's obligation 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 determining the gain or loss on the sale, the Corporation adjusts the transaction price and related gain (loss) on sale if a significant financing component is present.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events On February 28, 2023, Park National Bank reached an agreement with the DOJ to increase the efforts of Park National Bank to promote home lending in the Columbus, Ohio market. The agreement, which is reflected in the proposed consent order filed on February 28, 2023, in the U.S. District Court for the Southern District of Ohio (the “DOJ Consent Order”), serves to voluntarily resolve all claims of the U.S. alleging that Park National Bank’s mortgage lending practices within the Columbus, Ohio Metropolitan Statistical Area violated the Fair Housing Act and the Equal Credit Opportunity Act. In accordance with the terms of the DOJ Consent Order, Park National Bank, will invest a minimum of $7.75 million over five years in a loan subsidy fund to increase credit opportunities for home mortgage loans, home improvement loans, home refinance loans and home equity loans and lines of credit for consumers applying for loans in majority-minority census tracts ("MMCTs") in Fairfield, Franklin, Hocking, Licking, Morrow and Perry counties in Ohio (the “Columbus Lending Area”). Park National Bank will also devote a minimum of $500,000 over five years toward one or more community development partnership programs that provide services to residents of MMCTs in the Columbus Lending Area related to credit, financial education, homeownership and foreclosure prevention; and at least $750,000 over five years toward advertising, community outreach, consumer financial education and credit counseling in the Columbus Lending Area. Park National Bank will also establish one new mortgage loan production office and one new full-service branch in MMCTs in the Columbus Lending Area and hire four lenders, one of whom will be Spanish-speaking, focused on serving these communities. In addition, Park National Bank will continue to maintain, throughout the term of the DOJ Consent Order, Park National Bank’s full-time Director of Community Home Lending and Development position, who will oversee Park National Bank’s lending in MMCTs in the Columbus Lending Area. The DOJ Consent Order must be approved by the U.S. District Court for the Southern District of Ohio, Western Division, and once approved and entered by that Court, the DOJ Consent Order will resolve all claims by the U.S. against Park National Bank. Park is committed to investing at least $9.0 million over five years and will record the related expenses incurred in the period in which the associated activities occur.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of Park National Corporation and its subsidiaries (“Park”, the “Company” or the “Corporation”), unless the context otherwise requires. Material intercompany accounts and transactions have been eliminated.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP") requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.
Reclassifications	ReclassificationsCertain prior year amounts have been reclassified to conform with the current presentation. These reclassifications had no impact on net income or shareholders' equity.
Restrictions on Cash and Due from Banks	Restrictions on Cash and Due from Banks As of March 26, 2020, the Federal Reserve Board eliminated reserve requirements for all depository institutions.There were no compensating balance arrangements in existence at December 31, 2022 or 2021.
Investment Securities	Investment Securities Debt securities are classified upon acquisition into one of three categories: HTM, AFS, or trading (see Note 4 - Investment Securities). HTM securities are those debt securities that the Corporation has the positive intent and ability to hold to maturity and are recorded at amortized cost. AFS debt securities are those debt securities that would be available to be sold in the future in response to the Corporation’s liquidity needs, changes in market interest rates, and asset-liability management strategies, among other reasons. AFS debt securities are reported at fair value, with unrealized holding gains and losses excluded from earnings, but included in other comprehensive (loss) income, net of applicable income taxes. The Corporation did not hold any trading securities during any period presented. Interest income from debt securities includes amortization of purchase premium or discount. Premiums and discounts on investment securities are amortized on the level-yield method without anticipating prepayments, except for mortgage-backed securities where prepayments are anticipated. Premiums on callable debt securities are amortized to their earliest call date. Gains and losses realized on the sale of debt securities are recorded on the trade date and determined using the specific identification method. A debt security is placed on nonaccrual status at the time any principal or interest payments become 90 days past due. Interest accrued but not received for a security placed on nonaccrual status is reversed against interest income. ACL - Debt Securities AFS For debt securities AFS in an unrealized loss position, Park first assesses whether it intends to sell, or it is more likely than not that Park will be required to sell, the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security's amortized cost basis is written down to fair value through net income. For debt securities AFS that do not meet the aforementioned criteria, Park evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security is compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income (loss), net of applicable taxes. Changes in the ACL are recorded as a provision for (or recovery of) credit loss expense. Losses are charged against the ACL when management believes that uncollectibility of a debt security AFS is confirmed or when either of the criteria regarding intent or requirement to sell is met. Accrued interest receivable on debt securities AFS totaled $12.4 million and $6.3 million at December 31, 2022 and 2021, respectively, and is excluded from the estimate of credit losses. ACL - HTM Debt Securities Management measures expected credit losses on HTM debt securities on a collective basis by major security type. The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. Park does not currently hold any HTM debt securities. Equity Securities Equity securities, included within "Other investment securities" on the Consolidated Balance Sheets, are carried at fair value, with changes in fair value reported in net income. Equity securities without readily determinable fair values are carried at cost, minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment.
Federal Home Loan Bank (FHLB) and Federal Reserve Bank (FRB) Stock	Federal Home Loan Bank and Federal Reserve Bank of Cleveland Stock PNB is a member of the FHLB and the FRB. Members are required to own a certain amount of stock based on their level of borrowings and other factors and may invest in additional amounts. FHLB stock and FRB stock are classified as restricted securities and are carried at their redemption value within "Other investment securities" on the Consolidated Balance Sheets. Impairment is evaluated based on the ultimate recovery of par value. Both cash and stock dividends are reported as income.
Mortgage Loans Held For Sale	Loans Held for Sale Park has elected the fair value option for mortgage loans held for sale, which are carried at their fair value as of each balance sheet date.
Mortgage Banking Derivatives	Mortgage Banking DerivativesCommitments to fund mortgage loans (interest rate locks) to be sold into the secondary market and forward commitments for the future delivery of these mortgage loans are accounted for as free standing derivatives.  The fair value of an interest rate lock is recorded at the time the commitment to fund a mortgage loan is executed and is adjusted for the expected exercise of a commitment before a loan is funded.  In order to hedge against a change in interest rates resulting from the Company's commitments to fund loans, the Company enters into forward commitments for the future delivery of mortgage loans.  The fair value of Park's mortgage banking derivatives is estimated based on the change in mortgage interest rates from the date the interest on a loan is locked. The fair value of these mortgage banking derivatives is included in "Loans" in the Consolidated Balance Sheets. Changes in the fair value of these mortgage banking derivatives are included in "Other service income" in the Consolidated Statements of Income.
Financing Receivable [Policy Text Block]	Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at amortized cost. Amortized cost is the principal balance outstanding, net of purchase premiums and discounts and deferred loan fees and costs. Interest income is accrued on the unpaid principal balance. Accrued interest receivable totaled $22.3 million and $17.1 million at December 31, 2022 and 2021, respectively, and was reported in "Accrued interest receivable" on the Consolidated Balance Sheets. Late charges on loans are recognized as income when they are collected. Net loan origination fees and costs are deferred and recognized in interest income using the level-yield method without anticipating prepayments. Commercial loans include: (1) commercial, financial and agricultural loans; (2) commercial real estate loans; (3) those commercial loans in the construction real estate loan segment; (4) those commercial loans in the residential real estate loan segment; and (5) leases. Consumer loans include: (1) mortgage and installment loans included in the construction real estate segment; (2) mortgage, home equity lines of credit ("HELOCs"), and installment loans included in the residential real estate segment; and (3) all loans included in the consumer segment. Generally, commercial loans are placed on nonaccrual status at 90 days past due and consumer and residential mortgage loans are placed on nonaccrual status at 120 days past due. The delinquency status of a loan is based on contractual terms and not on how recently payments have been received. Park’s charge-off policy for commercial loans requires management to establish a specific reserve or record a charge-off when collection is in doubt and there is, or likely will be, a collateral shortfall related to the estimated value of the collateral securing a loan. The Company’s charge-off policy for consumer loans is dependent on the class of the loan. Residential mortgage loans, HELOCs, and consumer loans secured by residential real estate are typically charged down to the value of the collateral, less estimated selling costs, at 180 days past due. The charge-off policy for other consumer loans, primarily installment loans, requires a monthly review of delinquent loans and a complete charge-off for any account that reaches 120 days past due. In all cases, loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful. For loans which are on nonaccrual status, it is Park’s policy to reverse interest previously accrued on the loans against interest income. Interest on such loans may be recorded on a cash basis and be included in earnings only when Park expects to receive the entire recorded investment of the respective loans. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. A description of each segment of the loan portfolio, along with the risk characteristics of each segment, is included below: Commercial, financial and agricultural: Commercial, financial and agricultural ("C&I") loans are made for a wide variety of general corporate purposes, including financing for commercial and industrial properties, financing for equipment, inventory and accounts receivable, acquisition financing, commercial leasing, and loans originated by consumer finance companies. The term of each commercial loan varies by its purpose. Repayment terms are structured such that commercial loans will be repaid within the economic useful life of the underlying asset. Risk of loss on C&I loans largely depends upon general economic cycles, as they may adversely impact certain industries, competency of the borrower's management team, the quality of the underlying assets supporting the loans including accounts receivable, inventory, and equipment, and the accuracy of the borrower's financial reporting. Such risks are mitigated by generally requiring the borrower's owners to guaranty the loans. Commercial real estate: Commercial real estate (“CRE”) loans include mortgage loans to developers and owners of commercial real estate. The lending policy for CRE loans is designed to address the unique risk attributes of CRE lending. The collateral for these CRE loans is the underlying commercial real estate. Risk of loss on CRE loans largely depends upon the cash flow of the properties, which is influenced by the amount of vacancy experienced with respect to underlying real estate, the credit capacity of the tenants occupying the underlying real estate, and general economic trends, as they may adversely impact the value of a property. These risks are mitigated by generally requiring personal guarantees of the owners of the properties and by requiring appraisals pursuant to government regulations. Construction real estate : The Company defines construction loans as both commercial construction loans and residential construction loans where the loan proceeds are used exclusively for the improvement of real estate. Construction loans may be in the form of a permanent loan or a short-term construction loan, depending on the needs of the individual borrower. Construction financing is generally considered to involve a higher degree of risk of loss than long-term financing on improved, occupied real estate. Risk of loss on a construction loan depends largely upon the accuracy of the initial estimate of the property’s value at completion of construction and the estimated cost (including interest) of construction. If the estimate of construction cost proves to be inaccurate, Park may be required to advance funds beyond the amount originally committed to permit completion of the project. If the estimate of value proves inaccurate, Park may be confronted, at or prior to the maturity of the loan, with a project having a value insufficient to assure full repayment, should the borrower default. In the event that a default on a construction loan occurs and foreclosure follows, Park must take control of the project and attempt to either arrange for completion of construction or dispose of the unfinished project. Additional risks exist with respect to loans made to developers who do not have a buyer for the property, as the developer may lack funds to pay the loan if the property is not sold upon completion. Park attempts to reduce such risks on loans to developers by generally requiring personal guarantees and reviewing current personal financial statements and tax returns as well as other projects undertaken by the developer. Residential real estate: The Company defines residential real estate loans as first mortgages on individuals’ primary residences or second mortgages on individuals’ primary residences in the form of HELOCs or installment loans. Credit approval for residential real estate loans requires demonstration of sufficient income to repay the principal and interest and the real estate taxes and insurance, stable employment, an established credit record and a current independent third-party appraisal providing the market value of the real estate securing the loan. Residential real estate loans typically have longer terms and higher balances with lower yields as compared to consumer loans, but generally carry lower risks of default. The Dodd-Frank Wall Street Reform and Consumer Protection Act requires creditors to make a reasonable and good faith determination of a consumer's ability to repay any consumer credit transaction secured by a dwelling. Documentation and verification of income within defined time frames and not-to-exceed limits are bases for affirming ability to repay. Risk of loss largely depends upon factors affecting the borrower's ability to repay as well as the general economic trends as they may adversely impact the value of the property. These risks are mitigated by completing a comprehensive underwriting of the borrower and by requiring appraisals pursuant to government regulations. Consumer: The Company originates direct and indirect consumer loans, primarily automobile loans, to customers in the Company's primary market areas. Credit approval for consumer loans requires income sufficient to repay principal and interest due, stable employment, an established credit record and sufficient collateral for secured loans. Consumer loans typically have shorter terms and lower balances with higher yields as compared to real estate mortgage loans, but generally carry higher risks of default. Consumer loan collections are dependent on the borrower’s financial stability, and thus are more likely to be affected by adverse personal circumstances.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Concentration of Credit Risk Park's commercial loan portfolio includes loans to a wide variety of corporations and businesses across many industrial classifications in the 26 Ohio counties, four North Carolina counties, four South Carolina counties and one Kentucky county where PNB operates, with the exception of nationwide aircraft loans and nationwide asset-based lending to consumer finance companies. The primary industries represented by these customers include real estate rental and leasing, finance and insurance, construction, accommodation and food services, health care and social assistance, other services, manufacturing, retail trade, and agriculture, forestry, fishing and hunting.
Certain Loans and Debt Securities Acquired in Transfer, Recognizing Interest Income on Impaired Loans, Policy [Policy Text Block]	PCD Loans The Company has purchased loans, some of which have shown evidence of credit deterioration since origination. Upon adoption of ASC 326, Park elected to maintain pools of loans that were previously accounted for under ASC 310-30 and will continue to account for these pools as a unit of account. Loans are only removed from the existing pools if they are written off, paid off, or sold. Upon adoption of ASC 326, the allowance for credit losses was determined for each pool and added to the pool's carrying amount to establish a new amortized cost basis. The difference between the unpaid principal balance of the pool and the new amortized cost basis is the noncredit premium or discount, which will be amortized into interest income over the remaining life of the pool. Changes to the allowance for credit losses after adoption are recorded through provision for credit losses expense.
Allowance for Loan Losses	ACL - Loans The ACL is a valuation account that is deducted from the amortized cost of total loans to present the net amount expected to be collected on the loans. Loans are charged off against the allowance when management believes that the uncollectibility of a loan balance is confirmed. Expected recoveries cannot exceed the aggregate of the amounts previously charged-off and expected to be charged-off. Management estimates the allowance balance using relevant and available information from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical credit loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, delinquency level, or term as well as changes in environmental conditions, such as changes in unemployment rates, property values, or other relevant factors. ACL - Loans - Collectively Evaluated The ACL is measured on a collective pool basis when similar risk characteristics exist. Park has identified the following portfolio segments and measures the allowance for credit losses using the following methods: Portfolio Segment Measurement Method Loss Driver Commercial, financial and agricultural Commercial, financial and agricultural Discounted Cash Flow Ohio Unemployment, Ohio GDP PPP loans Other Not Applicable Overdrafts Historical Loss Experience Not Applicable Commercial real estate Discounted Cash Flow Ohio Unemployment, Ohio GDP Construction real estate: Commercial Discounted Cash Flow Ohio Unemployment, Ohio GDP Retail Discounted Cash Flow Ohio Unemployment, Ohio GDP Residential real estate: Commercial Discounted Cash Flow Ohio Unemployment, Ohio HPI Mortgage Discounted Cash Flow Ohio Unemployment, Ohio HPI HELOC Discounted Cash Flow Ohio Unemployment, Ohio HPI Installment Discounted Cash Flow Ohio Unemployment, Ohio HPI Consumer: Consumer Discounted Cash Flow Ohio Unemployment, Ohio GDP GFSC Discounted Cash Flow Ohio Unemployment, Ohio GDP Check loans Historical Loss Experience Not Applicable Leases Remaining Life Not Applicable Expected credit losses are estimated over the contractual term of the loans, adjusted for prepayments when appropriate. The contractual term excludes extensions, renewals, and modifications unless either of the following applies: management has a reasonable expectation at the reporting date that a TDR will be executed with an individual borrower or the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancellable by Park. In general, Park utilized a DCF method to estimate the quantitative portion of the allowance for credit losses for loans evaluated on a collective pooled basis. For each segment, a LDA was performed in order to identify appropriate loss drivers and create a regression model for use in forecasting cash flows. The LDA utilized Park's own Federal Financial Institutions Examination Council's ("FFIEC") Call Report data for the commercial, financial and agricultural and residential real estate segments. Peer data was incorporated into the analysis for the commercial real estate, construction real estate, and consumer segments. In creating the DCF model, Park established a one-year reasonable and supportable forecast period with a one-year straight line reversion to the long-term historical average. Park's policy is to utilize its own data, which includes loan-level loss data from 2013 through December 31, 2022, whenever possible. Park and peer FFIEC Call Report data are utilized when there are insufficient defaults for a statistically sound calculation, or if Park does not have its own loan-level detail reflecting similar economic conditions as the forecasted loss drivers. Key inputs into the DCF model include loan-level detail, including the amortized cost basis of individual loans, payment structure, loss history, and forecasted loss drivers. Park utilizes a third party to provide economic forecasts under various scenarios, which are weighted in order to reflect model risk in the then current economic environment. The weighting of the scenarios is evaluated on a quarterly basis considering the various scenarios in the context of the then current economic environment and presumed risk of loss. Additional key assumptions in the DCF model include the PD, LGD, and prepayment/curtailment rates. When possible, Park utilizes its own PDs for the reasonable and supportable forecast period. When it is not possible to use Park's own PDs, the LDA is utilized to determine PDs based on the forecasted economic factors. In all cases, the LDA is then utilized to determine the long-term historical average, which is reached over the reversion period. When possible, Park's utilizes its own LGDs for the reasonable and supportable forecast period. When it is not possible to use Park's own LGDs, the LGD is derived using a method referred to as Frye Jacobs. The Frye Jacobs method is a mathematical formula that traces the relationship between LGD and PD over time and projects the LGD based on the level of PD forecasted. In all cases, the Frye Jacobs method is utilized to calculate LGDs during the reversion period and long-term historical average. Prepayment and curtailment rates were calculated based on Park's own data utilizing a three-year average. When the discounted cash flow method is used to determine the allowance for credit losses, management incorporates expected prepayments to determine the effective interest rate utilized to discount expected cash flow. Park reviews various internal and external factors to consider the need for any qualitative adjustments to the quantitative model. Factors considered include the following: • The nature and volume of Park’s financial assets; • The existence, growth, and effect of any concentrations of credit; • The volume and severity of past due financial assets, the volume of nonaccrual assets, and the volume and severity of adversely classified or graded assets; • Park’s lending policies and procedures, including changes in lending strategies, underwriting standards and practices for collections, write-offs, and recoveries; • The quality of Park's credit review function; • The experience, ability, and depth of Park’s lending, investment, collection, and other relevant management and staff; • The effect of other external factors such as the regulatory, legal and technological environments, competition, geopolitical conflict, and events such as natural disasters or pandemics; • Actual and expected changes in international, national, regional, and local economic and business conditions and developments in the markets in which Park operates that affect the collectibility of financial assets; • Where the U.S. economy is within a given credit cycle; and • The extent that there is government assistance (stimulus). Allowance for Credit Losses - Loans - Individually Evaluated Loans that do not share risk characteristics are evaluated on an individual basis and are excluded from the collective evaluation. Park has determined that any commercial loans which have been placed on nonaccrual status or classified as TDRs are to be individually evaluated. Individual analysis establishes a specific reserve for loans in scope. Specific reserves on individually evaluated commercial loans are typically based on management’s best estimate of the fair value of collateral securing these loans, adjusted for selling costs as appropriate. Allowance for Credit Losses - Off-Balance Sheet Credit Exposures Park estimates expected credit losses over the contractual period in which Park is exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by Park. The allowance for credit losses on off-balance sheet credit exposures is adjusted within "Miscellaneous other expense" on the Consolidated Statements of Income. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over the commitments' respective estimated lives. Funding rates are based on a historical analysis of Park's portfolio, while estimates of credit losses are determined using the same loss rates as funded loans.
Troubled Debt Restructuring (TDRs)	Troubled Debt Restructurings ("TDRs") Management classifies loans as TDRs when a borrower is experiencing financial difficulty and Park has granted a concession. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of the borrower's debt in the foreseeable future without the modification. This evaluation is performed under the Company’s internal underwriting policy. Management’s policy is to modify loans by extending the term or by granting a temporary or permanent contractual interest rate below the market rate, not by forgiving debt. A court's discharge of a borrower's debt in a Chapter 7 bankruptcy is considered a concession when the borrower does not reaffirm the discharged debt. Additionally, during the COVID-19 pandemic, Park worked with borrowers and provided modifications in the form of either interest only deferral or principal and interest deferral, in each case, for initial periods up to 90 days. As necessary, Park made available a second 90-day interest only deferral or principal and interest deferral bringing the total potential deferral period to six months. A majority of these modifications were excluded from TDR classification under Section 4013 of the CARES Act or under applicable interagency guidance of the federal banking regulators. In accordance with this guidance, such modified loans were considered current and continued to accrue interest during the deferral period.
Bank Owned Life Insurance	Bank Owned Life Insurance Park has purchased insurance policies on the lives of directors and certain key officers. Bank owned life insurance is recorded at its cash surrender value (or the amount that can be realized).
Goodwill and Intangible Assets, Goodwill, Policy	Goodwill and Other Intangible Assets Goodwill represents the excess of the purchase price over net identifiable tangible and intangible assets acquired in a purchase business combination. Goodwill is not amortized to expense, but is subject to impairment tests annually, or more frequently, if events or changes in circumstances indicate that the asset might be impaired, by assessing qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If after assessing these events or circumstances, it is concluded that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then the performance of additional analysis is unnecessary. If the carrying amount of the goodwill exceeds the fair value, an impairment charge must be recorded in an amount equal to the excess, not to exceed the total goodwill allocated to the reporting unit.
Premises and Equipment	Premises and Equipment Land is carried at cost and is not subject to depreciation. Premises and equipment are carried at cost, less accumulated depreciation and amortization. Depreciation is generally provided on the straight-line method over the estimated useful lives of the related assets. Leasehold improvements are amortized over the shorter of the remaining lease period or the estimated useful lives of the improvements. Upon the sale or other disposal of an asset, the cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is recognized. Maintenance and repairs are charged to expense as incurred while renewals and improvements that extend the useful life of an asset are capitalized. Premises and equipment are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount of a particular asset may not be recoverable. The range of depreciable lives over which premises and equipment are being depreciated are: Buildings 30 Years Building improvements 5 to 10 Years Equipment, furniture and fixtures 3 to 12 Years Software 3 Years or the contractual useful life of the software Leasehold improvements Shorter of the remaining lease period or the estimated useful life of the improvement
Other Real Estate Owned (OREO)	Other Real Estate Owned Management transfers a loan to OREO at the time that Park takes deed/title to the asset. OREO is initially recorded at fair value less anticipated selling costs (net realizable value), establishing a new cost basis, and consists of property acquired through foreclosure and real estate held for sale. If the net realizable value is below the carrying value of the loan at the date of transfer, the difference is charged to the allowance for credit losses. If the net realizable value is above the carrying value of the loan at the date of transfer, any charged-off amounts are recovered and any additional amount is recorded within the line item "OREO valuation markup." These assets are subsequently accounted for at the lower of cost or fair value less costs to sell. Subsequent changes in the value of real estate are classified as OREO valuation adjustments, are reported as adjustments to the carrying amount of OREO, and recorded within the line item “Miscellaneous income". In certain circumstances where management believes the devaluation may not be permanent in nature, Park utilizes a valuation allowance to record OREO devaluations, which is expensed through the line item “Miscellaneous income". Costs relating to development and improvement of such properties are capitalized (not in excess of fair value less estimated costs to sell), and costs relating to holding the properties are charged to the line item "Miscellaneous expense".
Finance, Loan and Lease Receivables, Held for Investments, Foreclosed Assets Policy [Policy Text Block]	Foreclosed Assets Foreclosed assets include non-real estate assets where Park, as creditor, has received physical possession of a borrower’s assets, regardless of whether formal foreclosure proceedings take place. Additionally, TDRs in which Park obtains one of more of the debtor’s non-real estate assets in place of all or part of the receivable are accounted for as foreclosed assets. Foreclosed assets are initially recorded as fair value less costs to sell when acquired, establishing a new cost basis. Operating costs after acquisition are expensed as incurred. As of December 31, 2022 and 2021, Park had $605,000 and $3.3 million, respectively, of foreclosed assets included within “Other assets.”
Mortgage Loan Servicing Rights	Mortgage Servicing Rights When Park sells mortgage loans with servicing retained, MSRs are recorded at fair value with the income statement effect recorded in "Other service income". Capitalized MSRs are amortized in proportion to and over the period of the estimated future servicing income of the underlying loan and are included within “Other service income”. MSRs are assessed for impairment quarterly, based on fair value, with any impairment recognized through a valuation allowance. The fair value of MSRs is determined by discounting estimated future cash flows from the servicing assets, using market discount rates and expected future prepayment rates. In order to calculate fair value, the sold loan portfolio is stratified into homogeneous pools of like categories. (See Note 12 - Loan Servicing.)
Lessee, Leases	Leases Management determines if an arrangement is or contains a lease at contract inception. If an arrangement is determined to be or contain a lease, Park recognizes a ROU asset and a lease liability at the lease commencement date. Leases are classified as operating or finance leases at the lease commencement date. At December 31, 2022 and 2021, all of Park's leases were classified as operating leases. Park elected the practical expedient, by class of underlying asset, to not separate non-lease components from the associated lease components. Additionally, Park has elected not to recognize ROU assets and lease liabilities for short-term leases that have a lease term of 12 months or less. Park recognizes the lease payments associated with its short-term leases as an expense on a cash basis. Park’s lease liability is initially and subsequently measured as the present value of the unpaid lease payments at the lease commencement date. Key estimates and judgments related to the lease liability include how management determines (1) the discount rate it uses to discount the unpaid lease payments to present value, (2) the lease term, and (3) lease payments. • ASC 842 requires a lessee to discount its unpaid lease payments using the interest rate implicit in the lease or, if that rate cannot be readily determined, its incremental borrowing rate. Generally, Park's management cannot determine the interest rate implicit in a lease because it does not have access to the lessor’s estimated residual value or the amount of the lessor’s deferred initial direct costs. Therefore, Park utilizes its incremental borrowing rate as the discount rate for leases. Park’s incremental borrowing rate for a lease is the rate of interest Park would have to pay on a collateralized basis to borrow an amount equal to the lease payments under similar terms. To manage its capital and liquidity needs, Park periodically obtains wholesale funding from the FHLB on an over-collateralized basis. The impact of utilizing an interest rate on an over-collateralized borrowing versus a fully collateralized borrowing is not material. Therefore, the FHLB yield curve was selected by Park's management as a baseline to determine Park’s discount rates for leases. • The lease term for all of Park's leases includes the noncancellable period of the lease plus any additional periods covered by either Park's option to extend (or not to terminate) the lease that Park is reasonably certain to exercise, or an option to extend (or not to terminate) the lease controlled by the lessor. If a lease contract contains multiple renewal options, Park's management generally models lease cash flows through the first renewal option period unless the contract contains economic incentives or other conditions that increase or decrease the likelihood that additional renewals are reasonably certain to be exercised. • Lease payments included in the measurement of the lease liability are comprised of the following: ◦ Fixed payments, including in-substance fixed payments, owed over the lease term; ◦ For certain of Park's gross real estate leases, non-lease components such as real estate taxes, insurance, and common area maintenance; and ◦ Variable lease payments that depend on an index or rate, initially measured using the index or rate at the lease commencement date. The ROU asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for lease payments made at or before the lease commencement date, plus any initial direct costs incurred less any lease incentives received. For operating leases, the ROU asset is subsequently measured throughout the lease term at the carrying amount of the lease liability, plus initial direct costs, plus (minus) any prepaid (accrued) lease payments, less the unamortized balance of lease incentives received. Lease expense for lease payments is recognized on a straight-line basis over the lease term.
Consolidated Statement of Cash Flows	Consolidated Statements of Cash Flows Cash and cash equivalents include cash and cash items, amounts due from banks, and money market instruments. Generally, money market instruments are purchased and sold for one-day periods.
Loss Contingencies and Guarantees	Loss Contingencies Park is routinely engaged in various litigation and other legal matters. These include defending against claims of improper loan, deposit account, and other banking practices, as well as trust and investment, intellectual property, contract, and other legal matters, and Park has a number of unresolved lawsuits and open matters pending resolution. In addition, Park is party to litigation involving the collection of delinquent accounts, challenges to security interests in collateral, foreclosure lawsuits, and similar matters which are part of, or incidental to, the ordinary course of business. While the ultimate liability with respect to these matters and claims cannot be determined at this time, management believes that losses, damages, or liabilities, if any, and other amounts relating to pending matters are not likely to be material to Park's consolidated financial position or results of operations. Reserves are established for these various litigation and other legal matters, when appropriate under FASB ASC Topic 450, Contingencies, based in part upon the advice of legal counsel.
Income Tax, Policy [Policy Text Block]	Income Taxes Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax basis of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. An uncertain tax position is recognized as a benefit only if it is “more-likely-than-not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The benefit recognized for a tax position that meets the “more-likely-than-not” criteria is measured based on the largest benefit that is more than 50 percent likely to be realized, taking into consideration the amounts and probabilities of the outcome upon settlement. For tax positions not meeting the “more-likely-than-not” test, no tax benefit is recorded. Park recognizes any interest and penalties related to income tax matters in income tax expense.
Treasury Shares	Treasury Shares The purchase of Park’s common shares to be held in treasury is recorded at cost. At the date of retirement or subsequent reissuance, the treasury shares account is reduced by the weighted average cost of the common shares retired or reissued.
Policyholders' Dividend [Policy Text Block]	Dividend Restriction Banking regulations require the maintenance of certain capital levels and may limit the dividends paid by a bank to its parent holding company or by the parent holding company to its shareholders. (See Note 25 - Dividend Restrictions and Note 28 - Capital Ratios.)
Comprehensive Income	Comprehensive Income Comprehensive income consists of net income and other comprehensive income (loss). Other comprehensive income (loss) includes unrealized gains and losses on debt securities available for sale, changes in the funded status of the Company’s defined benefit pension plan and unrealized gains and losses on cash flow hedges which are also recognized as separate components of equity.
Stock Based Compensation	Share-Based Compensation Compensation cost is recognized for restricted stock units and stock awards issued to employees and directors, respectively, based on the fair value of these awards at the date of grant. The market price of Park’s common shares at the date of grant is used to estimate the fair value of restricted stock units and stock awards. Compensation cost is recognized on a straight-line basis over the required service period, generally defined as the vesting period and is recorded in "Salaries" expense. (See Note 20 - Share-Based Compensation.) The Company's accounting policy is to recognize forfeitures as they occur.
Loan Commitments and Related Financial Instruments	Loan Commitments and Related Financial InstrumentsFinancial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.
Fair Value Measurement	Fair Value Measurement Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in Note 27 - Fair Value. Fair value estimates involve uncertainties and matters of significant judgment regarding
Derivatives, Policy	Derivatives At the inception of a derivative contract, Park designates the derivative as one of three types based on Park's intentions and belief as to the likely effectiveness as a hedge. These three types are (1) a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (“fair value hedge”), (2) a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (“cash flow hedge”), or (3) an instrument with no hedging designation (“stand-alone derivative”). Park does not have any fair value hedges. For a cash flow hedge, the gain or loss on the derivative is reported in other comprehensive income (loss) and is reclassified into net income in the same periods during which the hedged transaction affects net income. Changes in the fair value of derivatives that do not qualify for hedge accounting are reported currently in net income, as non-interest income. Net cash settlements on derivatives that qualify for hedge accounting are recorded in interest income or interest expense, based on the item being hedged. Net cash settlements on derivatives that do not qualify for hedge accounting are reported in non-interest income. Cash flows on hedges are classified in the Consolidated Statements of Cash Flow under the same item as the cash flows of the items being hedged. Park formally documents the relationship between derivatives and hedged items, as well as the risk-management objective and the strategy for undertaking the hedge transaction at the inception of the hedging relationship. The documentation includes linking cash flow hedges to specific assets and liabilities on the Consolidated Balance Sheets. Park also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives that are used are highly effective in offsetting changes in cash flows of the hedged items. Park discontinues hedge accounting when it determines that a derivative is no longer effective in offsetting cash flows of the hedged item, the derivative is settled or terminates, or treatment of the derivative as a hedge is no longer appropriate or intended. When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded as non-interest income. When a cash flow hedge is discontinued but the hedged cash flows are still expected to occur, gains or losses that were accumulated in other comprehensive income are amortized into net income over the same periods that the hedged transactions will affect earnings. The Company is exposed to losses if a counterparty fails to make its payments under a contract in which the Company is in the net receiving position. The Company anticipates that the counterparties will be able to fully satisfy their obligations under the outstanding contracts. All the contracts to which the Company is party settle monthly or quarterly.
Transfers and Financial Assets	Transfers of Financial Assets Transfers of financial assets are accounted for as sales, when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Company, the transferee obtains the right (free of conditions that constrain the transferee from taking advantage of that right) to pledge or exchange the transferred assets, and the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Retirement Plans	Retirement Plans Pension expense is the net of service and interest cost, return on plan assets and amortization of gains and losses not immediately recognized. The service cost component of pension expense is recorded within "Employee benefits" on the Consolidated Statements of Income. All other components of pension expense are recorded within "Other components of net periodic benefit income" on the Consolidated Statements of Income. Employee KSOP plan expense is the amount of matching contributions to Park's Employees Stock Ownership Plan. Deferred compensation and supplemental retirement plan expense allocate the benefits over years of service. (See Note 21 - Benefit Plans.)
Earnings Per Common Share	Earnings Per Common Share Basic earnings per common share is net income divided by the weighted average number of common shares outstanding during the period. Diluted earnings per common share includes the dilutive effect of additional potential common shares issuable under restricted stock unit awards. (See Note 20 - Share-Based Compensation and Note 24 - Earnings Per Common Share.)

Unrealized Gain (Loss) on Investments	At December 31, 2022, Park’s debt security portfolio consisted of $1.7 billion of securities, $1.6 billion of which were in an unrealized loss position with unrealized losses of $122.8 million. Of the $1.6 billion of securities in an unrealized loss position, $413.1 million were in an unrealized loss position for 12 months or longer. Of the $122.8 million in unrealized losses, an aggregate of $84.4 million were related to Park's "Obligations of U.S. Government sponsored entities" portfolio and Park's "U.S. Government sponsored entities' asset-backed securities" portfolio. For non-agency debt securities, Park verified that the current credit ratings remain above investment grade. Management periodically reviews the credit profile of each non-agency debt security and assesses whether any impairment to the contractually obligated cash flow is likely to occur. Based on these reviews, management has concluded that the underlying creditworthiness for each security remains sufficient to maintain required payment obligations and, therefore, unrealized losses have not been recognized into net income. Management does not intend to sell, and it is not more likely than not that management would be required to sell, the securities prior to their anticipated recovery in respect of the unrealized losses. Management believes the value will recover as the securities approach maturity or market rates change. There was no allowance for credit losses recorded for debt securities AFS at December 31, 2022 and December 31, 2021. Additionally, for the years ended December 31, 2022, 2021, and 2020, there were no credit-related investment impairment losses recognized.

Investment securities: Fair values for investment securities are based on quoted market prices, where available (Level 1). If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments (Level 2). For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows (Level 3). Fair value swap: The fair value of the swap agreement entered into with the purchaser of the Visa Class B shares represents an internally developed estimate of the exposure based upon probability-weighted potential Visa litigation losses and is classified as Level 3. Mortgage interest rate lock commitments: Mortgage IRLCs are based on current secondary market pricing and are classified as Level 2. Mortgage loans held for sale: Mortgage loans held for sale are carried at their fair value. Mortgage loans held for sale are estimated using market prices for similar product types and, therefore, are classified in Level 2.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Financing Receivable [Policy Text Block]	Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at amortized cost. Amortized cost is the principal balance outstanding, net of purchase premiums and discounts and deferred loan fees and costs. Interest income is accrued on the unpaid principal balance. Accrued interest receivable totaled $22.3 million and $17.1 million at December 31, 2022 and 2021, respectively, and was reported in "Accrued interest receivable" on the Consolidated Balance Sheets. Late charges on loans are recognized as income when they are collected. Net loan origination fees and costs are deferred and recognized in interest income using the level-yield method without anticipating prepayments. Commercial loans include: (1) commercial, financial and agricultural loans; (2) commercial real estate loans; (3) those commercial loans in the construction real estate loan segment; (4) those commercial loans in the residential real estate loan segment; and (5) leases. Consumer loans include: (1) mortgage and installment loans included in the construction real estate segment; (2) mortgage, home equity lines of credit ("HELOCs"), and installment loans included in the residential real estate segment; and (3) all loans included in the consumer segment. Generally, commercial loans are placed on nonaccrual status at 90 days past due and consumer and residential mortgage loans are placed on nonaccrual status at 120 days past due. The delinquency status of a loan is based on contractual terms and not on how recently payments have been received. Park’s charge-off policy for commercial loans requires management to establish a specific reserve or record a charge-off when collection is in doubt and there is, or likely will be, a collateral shortfall related to the estimated value of the collateral securing a loan. The Company’s charge-off policy for consumer loans is dependent on the class of the loan. Residential mortgage loans, HELOCs, and consumer loans secured by residential real estate are typically charged down to the value of the collateral, less estimated selling costs, at 180 days past due. The charge-off policy for other consumer loans, primarily installment loans, requires a monthly review of delinquent loans and a complete charge-off for any account that reaches 120 days past due. In all cases, loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful. For loans which are on nonaccrual status, it is Park’s policy to reverse interest previously accrued on the loans against interest income. Interest on such loans may be recorded on a cash basis and be included in earnings only when Park expects to receive the entire recorded investment of the respective loans. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. A description of each segment of the loan portfolio, along with the risk characteristics of each segment, is included below: Commercial, financial and agricultural: Commercial, financial and agricultural ("C&I") loans are made for a wide variety of general corporate purposes, including financing for commercial and industrial properties, financing for equipment, inventory and accounts receivable, acquisition financing, commercial leasing, and loans originated by consumer finance companies. The term of each commercial loan varies by its purpose. Repayment terms are structured such that commercial loans will be repaid within the economic useful life of the underlying asset. Risk of loss on C&I loans largely depends upon general economic cycles, as they may adversely impact certain industries, competency of the borrower's management team, the quality of the underlying assets supporting the loans including accounts receivable, inventory, and equipment, and the accuracy of the borrower's financial reporting. Such risks are mitigated by generally requiring the borrower's owners to guaranty the loans. Commercial real estate: Commercial real estate (“CRE”) loans include mortgage loans to developers and owners of commercial real estate. The lending policy for CRE loans is designed to address the unique risk attributes of CRE lending. The collateral for these CRE loans is the underlying commercial real estate. Risk of loss on CRE loans largely depends upon the cash flow of the properties, which is influenced by the amount of vacancy experienced with respect to underlying real estate, the credit capacity of the tenants occupying the underlying real estate, and general economic trends, as they may adversely impact the value of a property. These risks are mitigated by generally requiring personal guarantees of the owners of the properties and by requiring appraisals pursuant to government regulations. Construction real estate : The Company defines construction loans as both commercial construction loans and residential construction loans where the loan proceeds are used exclusively for the improvement of real estate. Construction loans may be in the form of a permanent loan or a short-term construction loan, depending on the needs of the individual borrower. Construction financing is generally considered to involve a higher degree of risk of loss than long-term financing on improved, occupied real estate. Risk of loss on a construction loan depends largely upon the accuracy of the initial estimate of the property’s value at completion of construction and the estimated cost (including interest) of construction. If the estimate of construction cost proves to be inaccurate, Park may be required to advance funds beyond the amount originally committed to permit completion of the project. If the estimate of value proves inaccurate, Park may be confronted, at or prior to the maturity of the loan, with a project having a value insufficient to assure full repayment, should the borrower default. In the event that a default on a construction loan occurs and foreclosure follows, Park must take control of the project and attempt to either arrange for completion of construction or dispose of the unfinished project. Additional risks exist with respect to loans made to developers who do not have a buyer for the property, as the developer may lack funds to pay the loan if the property is not sold upon completion. Park attempts to reduce such risks on loans to developers by generally requiring personal guarantees and reviewing current personal financial statements and tax returns as well as other projects undertaken by the developer. Residential real estate: The Company defines residential real estate loans as first mortgages on individuals’ primary residences or second mortgages on individuals’ primary residences in the form of HELOCs or installment loans. Credit approval for residential real estate loans requires demonstration of sufficient income to repay the principal and interest and the real estate taxes and insurance, stable employment, an established credit record and a current independent third-party appraisal providing the market value of the real estate securing the loan. Residential real estate loans typically have longer terms and higher balances with lower yields as compared to consumer loans, but generally carry lower risks of default. The Dodd-Frank Wall Street Reform and Consumer Protection Act requires creditors to make a reasonable and good faith determination of a consumer's ability to repay any consumer credit transaction secured by a dwelling. Documentation and verification of income within defined time frames and not-to-exceed limits are bases for affirming ability to repay. Risk of loss largely depends upon factors affecting the borrower's ability to repay as well as the general economic trends as they may adversely impact the value of the property. These risks are mitigated by completing a comprehensive underwriting of the borrower and by requiring appraisals pursuant to government regulations. Consumer: The Company originates direct and indirect consumer loans, primarily automobile loans, to customers in the Company's primary market areas. Credit approval for consumer loans requires income sufficient to repay principal and interest due, stable employment, an established credit record and sufficient collateral for secured loans. Consumer loans typically have shorter terms and lower balances with higher yields as compared to real estate mortgage loans, but generally carry higher risks of default. Consumer loan collections are dependent on the borrower’s financial stability, and thus are more likely to be affected by adverse personal circumstances.

Subsequent Event, Description		On February 28, 2023, Park National Bank reached an agreement with the DOJ to increase the efforts of Park National Bank to promote home lending in the Columbus, Ohio market. The agreement, which is reflected in the proposed consent order filed on February 28, 2023, in the U.S. District Court for the Southern District of Ohio (the “DOJ Consent Order”), serves to voluntarily resolve all claims of the U.S. alleging that Park National Bank’s mortgage lending practices within the Columbus, Ohio Metropolitan Statistical Area violated the Fair Housing Act and the Equal Credit Opportunity Act.In accordance with the terms of the DOJ Consent Order, Park National Bank, will invest a minimum of $7.75 million over five years in a loan subsidy fund to increase credit opportunities for home mortgage loans, home improvement loans, home refinance loans and home equity loans and lines of credit for consumers applying for loans in majority-minority census tracts ("MMCTs") in Fairfield, Franklin, Hocking, Licking, Morrow and Perry counties in Ohio (the “Columbus Lending Area”). Park National Bank will also devote a minimum of $500,000 over five years toward one or more community development partnership programs that provide services to residents of MMCTs in the Columbus Lending Area related to credit, financial education, homeownership and foreclosure prevention; and at least $750,000 over five years toward advertising, community outreach, consumer financial education and credit counseling in the Columbus Lending Area. Park National Bank will also establish one new mortgage loan production office and one new full-service branch in MMCTs in the Columbus Lending Area and hire four lenders, one of whom will be Spanish-speaking, focused on serving these communities. In addition, Park National Bank will continue to maintain, throughout the term of the DOJ Consent Order, Park National Bank’s full-time Director of Community Home Lending and Development position, who will oversee Park National Bank’s lending in MMCTs in the Columbus Lending Area.The DOJ Consent Order must be approved by the U.S. District Court for the Southern District of Ohio, Western Division, and once approved and entered by that Court, the DOJ Consent Order will resolve all claims by the U.S. against Park National Bank.Park is committed to investing at least $9.0 million over five years and will record the related expenses incurred in the period in which the associated activities occur.
