Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis Of Presentation	Basis of Presentation The accompanying unaudited consolidated condensed financial statements included in this report have been prepared for Park National Corporation (sometimes also referred to as the “Registrant”) and its subsidiaries. Unless the context otherwise requires, references to "Park", the "Corporation" or the "Company" and similar terms mean Park National Corporation and its subsidiaries. In the opinion of management, all adjustments (consisting of normal recurring accruals) necessary for a fair presentation of the results of operations for the interim periods included herein have been made. The results of operations for the three-month and six-month periods ended June 30, 2017 are not necessarily indicative of the operating results to be anticipated for the fiscal year ending December 31, 2017. The accompanying unaudited consolidated condensed financial statements have been prepared in accordance with the instructions for Form 10-Q and, therefore, do not include all information and footnotes necessary for a fair presentation of the condensed balance sheets, condensed statements of income, condensed statements of comprehensive income, condensed statements of changes in shareholders’ equity and condensed statements of cash flows in conformity with United States ("U.S.") generally accepted accounting principles (“U.S. GAAP”). These financial statements should be read in conjunction with the consolidated financial statements incorporated by reference in the Annual Report on Form 10-K of Park for the fiscal year ended December 31, 2016 from Park’s 2016 Annual Report to Shareholders (“Park's 2016 Annual Report”). Certain prior period amounts have been reclassified to conform to the current period presentation. Park’s significant accounting policies are described in Note 1 of the Notes to Consolidated Financial Statements included in Park’s 2016 Annual Report. For interim reporting purposes, Park follows the same basic accounting policies, as updated by the information contained in this report, and considers each interim period an integral part of an annual period.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements ASU 2014-09 - Revenue from Contracts with Customers (Topic 606): In May 2014, the Financial Accounting Standards Board (the "FASB") issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). The ASU creates a new topic, Topic 606, to provide guidance on revenue recognition for entities that enter into contracts with customers to transfer goods or services or enter into contracts for the transfer of nonfinancial assets. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Additional disclosures are required to provide quantitative and qualitative information regarding the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The new guidance is effective for annual reporting periods, and interim reporting periods within those annual periods, beginning after December 15, 2017. While interest income is specifically out of scope of this guidance, management is currently evaluating the revenue streams within "Other income" to assess the applicability of this guidance. Specifically, management is evaluating the impact of this new guidance on deposit fees recorded within "Service charges on deposit accounts" and trust income within "Income from fiduciary activities." ASU 2016-01 - Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. In January 2016, the FASB issued ASU 2016-01 - Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. Changes to the current U.S. GAAP model primarily affect the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. In addition, the ASU clarifies guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale securities. The new guidance is effective for annual reporting periods and interim reporting periods within those annual periods, beginning after December 15, 2017. The adoption of this guidance is not expected to have a material impact on Park's consolidated financial statements, but will impact the fair value disclosures in Note 14. ASU 2016-02 - Leases (Topic 842): In February 2016, the FASB issued ASU 2016-02 - Leases (Topic 842) . The ASU will require all organizations that lease assets to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. Additional qualitative and quantitative disclosures will be required so that users can understand more about the nature of an entity’s leasing activities. The new guidance is effective for annual reporting periods and interim reporting periods within those annual periods, beginning after December 15, 2018. Early adoption is permitted. Management is currently analyzing data on leased assets. The adoption of this guidance is expected to increase both assets and liabilities, but is not expected to have a material impact on Park's consolidated statement of income. ASU 2016-09 - Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting: In March 2016, FASB issued ASU 2016-09 - Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting . The ASU provides simplification for several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The new guidance was effective for annual reporting periods and interim reporting periods within those annual periods, beginning after December 15, 2016. Early adoption was permitted. The adoption of this guidance on January 1, 2017 did not have a material impact on Park's consolidated financial statements. ASU 2016-13 - Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments: In June 2016, FASB issued ASU 2016-13 - Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . The new guidance replaces the incurred loss model with an expected loss model, which is referred to as the current expected credit loss ("CECL") model. The CECL model is applicable to the measurement of credit losses on financial assets measured at amortized cost, including loan receivables, held-to-maturity 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 model requires an entity to estimate the credit losses over the life of an asset or off-balance sheet exposure. The new guidance is effective for annual reporting periods and interim reporting periods within those annual periods, beginning after December 15, 2019. Early adoption is permitted for annual reporting periods and interim reporting periods within those annual periods, beginning after December 15, 2018. Management is currently evaluating the impact of the adoption of this guidance on Park's consolidated financial statements. We anticipate that the adoption of the CECL model will result in a material increase to Park's allowance for loan losses. Management has established a committee to oversee the implementation of CECL. This committee is currently assessing the data and system requirements necessary for adoption. Management plans to run our current incurred loss model and a CECL model concurrently for 12 months prior to the adoption of this guidance on January 1, 2020. ASU 2016-15 - Statement of Cash Flows (Topic 203): Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force): In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 203): Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force) . This ASU provides guidance on eight specific cash flow issues where current U.S. GAAP is either unclear or does not include specific guidance. The new guidance is effective for annual reporting periods, and interim reporting periods within those annual periods, beginning after December 15, 2017. As such transactions arise, management will utilize the updated guidance within Park’s consolidated statements of cash flows. ASU 2017-04 - Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment: In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This ASU eliminates Step 2 from the goodwill impairment test. Instead, under the new guidance, an entity is to perform its annual goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge would be recognized for the amount by which the carrying amount exceeds the reporting unit's fair value. The new guidance is effective for annual reporting periods, and interim reporting periods within those annual periods, beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of this guidance with Park's April 1, 2017 annual goodwill impairment test did not have an impact on Park's consolidated financial statements. ASU 2017-07 - Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost: In March 2017, the FASB issued ASU 2017-07 - Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This ASU requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component. The new guidance is effective for annual reporting periods, and interim reporting periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted for interim or annual periods. The adoption of this guidance is not expected to have a material impact on Park's consolidated financial statements. ASU 2017-08 - Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities: In March 2017, the FASB issued ASU 2017-08 - Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. This ASU amends the amortization period for certain purchased callable debt securities held at a premium. It shortens the amortization period for the premium to the earliest call date. Under current U.S. GAAP, premiums on callable debt securities generally are amortized to the maturity date. The new guidance is effective for annual reporting periods, and interim reporting periods within those annual periods, beginning after December 15, 2018. Early adoption is permitted for interim or annual periods. The adoption of this guidance is not expected to have a material impact on Park's consolidated financial statements. ASU 2017-09 - Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting: In May 2017, the FASB issued ASU 2017-09 - Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting. This ASU amends the guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. The new guidance is effective for annual reporting periods, and interim reporting periods within those annual periods, beginning after December 15, 2017.

At June 30, 2017 and December 31, 2016 , there were $5.7 million and $24.7 million , respectively, of partial charge-offs on loans individually evaluated for impairment with no related allowance recorded and $3.4 million and $0.2 million , respectively, of partial charge-offs on loans individually evaluated for impairment that also had a specific reserve allocated. The allowance for loan losses included specific reserves related to loans individually evaluated for impairment at June 30, 2017 and December 31, 2016 of $4.1 million and $0.5 million , respectively. These loans with specific reserves had a recorded investment of $18.0 million and $2.1 million as of June 30, 2017 and December 31, 2016 , respectively. Interest income on nonaccrual loans individually evaluated for impairment is recognized on a cash basis only when Park expects to receive the entire recorded investment of the loan. Interest income on accruing TDRs individually evaluated for impairment continues to be recorded on an accrual basis.

Credit Quality Indicators Management utilizes past due information as a credit quality indicator across the loan portfolio. Past due information as of June 30, 2017 and December 31, 2016 is included in the tables above. The past due information is the primary credit quality indicator within the following classes of loans: (1) mortgage loans and installment loans in the construction real estate segment; (2) mortgage loans, HELOC and installment loans in the residential real estate segment; and (3) consumer loans. The primary credit indicator for commercial loans is based on an internal grading system that grades 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 loan loss reserve percentage is allocated 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 6 (substandard), also considered to be watch list credits, are considered to represent higher credit risk and, as a result, a higher loan loss reserve percentage is allocated 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 that are 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 impaired category. A loan is deemed impaired 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.

Troubled Debt Restructurings ("TDRs") Management 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. Certain loans which were modified during the six -month periods ended June 30, 2017 and June 30, 2016 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. 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, 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 would 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. There were no TDR classifications removed during the three-month or six-month periods ended June 30, 2017 . The TDR classification was removed on $917,000 of loans during the three -month period ended June 30, 2016 and $1.7 million of loans during the six-month period ended June 30, 2016, respectively. At June 30, 2017 and December 31, 2016 , there were $43.9 million and $46.9 million , respectively, of TDRs included in the nonaccrual loan totals. At June 30, 2017 and December 31, 2016 , $36.7 million and $38.0 million , respectively, of these nonaccrual TDRs were performing in accordance with the terms of the restructured note. As of June 30, 2017 and December 31, 2016 , loans with a recorded investment of $18.7 million and $18.2 million , respectively, were included in accruing TDR loan totals. Management will continue to review the restructured loans and may determine it appropriate to move certain nonaccrual TDRs to accrual status in the future. At June 30, 2017 and December 31, 2016 , Park had commitments to lend $0.9 million and $0.7 million , respectively, of additional funds to borrowers whose outstanding loan terms had been modified in a TDR. There were $0.6 million and $0.2 million of specific reserves related to TDRs at June 30, 2017 and December 31, 2016 , respectively. Modifications made in 2016 and 2017 were largely the result of renewals and extending the maturity date of the loan at terms consistent with the original note. 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 impaired loans, and thus were also previously evaluated for impairment under Accounting Standards Codification (ASC) 310. Additional specific reserves of $10,000 and $950,000 were recorded during the three -month periods ended June 30, 2017 and June 30, 2016 , respectively, as a result of TDRs identified in the respective periods. Additional specific reserves of $290,000 and $975,000 were recorded during the six-month periods ended June 30, 2017 and June 30, 2016 , respectively, as a result of TDRs identified in the respective periods. The terms of certain other loans were modified during the six-month periods ended June 30, 2017 and June 30, 2016 that did not meet the definition of a TDR. Modified substandard commercial loans which did not meet the definition of a TDR had a total recorded investment as of June 30, 2017 and June 30, 2016 of $111,000 and $33,000 , respectively. The renewal/modification of these loans: (1) resulted in a delay in a payment that was considered to be insignificant, or (2) resulted in Park obtaining additional collateral or guarantees that improved the likelihood of the ultimate collection of the loans such that each modification was deemed to be at market terms. Modified consumer loans which did not meet the definition of a TDR had a total recorded investment of $5.0 million and $4.4 million , as of June 30, 2017 and June 30, 2016 , respectively. Many of these loans were to borrowers who were not experiencing financial difficulties but who were looking to reduce their cost of funds. The following tables detail the number of contracts modified as TDRs during the three -month and six-month periods ended June 30, 2017 and June 30, 2016 , as well as the recorded investment of these contracts at June 30, 2017 and June 30, 2016 . The recorded investment pre- and post-modification is generally the same due to the fact that Park does not typically provide for forgiveness of principal.

Allowance for Loan and Lease Losses Write-offs, Net [Abstract]
Allowance For Loan Losses	Allowance for Loan Losses The allowance for loan losses ("ALLL") is that amount management believes is adequate to absorb probable incurred credit losses in the loan portfolio based on management’s evaluation of various factors including overall growth in the loan portfolio, an analysis of individual loans, prior and current loss experience, and current economic conditions. A provision for loan losses is charged to operations based on management’s periodic evaluation of these and other pertinent factors as discussed within Note 1 of the Notes to Consolidated Financial Statements included in Park’s 2016 Annual Report. Loss factors are reviewed quarterly and updated at least annually to reflect recent loan loss history and incorporate current risk and trends which may not be recognized in historical data. The historical loss factors were last updated in the fourth quarter of 2016 to incorporate losses through December 31, 2016. The activity in the allowance for loan losses for the three -month and six -month periods ended June 30, 2017 and June 30, 2016 is summarized in the following tables.

Should the impairment of any of these securities become other-than-temporary, the cost basis of the investment will be reduced and the resulting loss recognized within net income in the period the other-than-temporary impairment is identified. Park’s U.S. Government sponsored entities' asset-backed securities consist of 15 -year residential mortgage-backed securities and collateralized mortgage obligations. The amortized cost and estimated fair value of investments in debt securities at June 30, 2017 , are shown in the following table by contractual maturity, except for asset-backed securities, which are shown as a single total, due to the unpredictability of the timing of principal repayments.

The aggregate taxable equivalent adjustment was $1.7 million for the six months ended June 30, 2017. All of Park’s securities shown in the table above as obligations of U.S. Treasury and other U.S. Government sponsored entities' notes are callable notes. These callable notes have final maturities of 0.4 years to 3 years. Of the $268.7 million reported at June 30, 2017 , none were expected to be called. The remaining average life of the entire investment portfolio is estimated to be 4.4 years. There were no sales of investment securities during the three-month or six-month periods ended June 30, 2017 or 2016. Investment securities having an amortized cost of $944 million and $937 million at June 30, 2017 and December 31, 2016, respectively, were pledged to collateralize government and trust department deposits in accordance with federal and state requirements, to secure repurchase agreements sold and as collateral for FHLB advance borrowings.

The 2013 Incentive Plan made equity-based awards and cash-based awards available for grant to participants in the form of incentive stock options, nonqualified stock options, stock appreciation rights (“SARs”), restricted common shares (“Restricted Stock”), restricted stock unit awards that may be settled in common shares, cash or a combination of the two (“Restricted Stock Units”), unrestricted common shares (“Other Stock-Based Awards”) and cash-based awards. Under the 2013 Incentive Plan, 600,000 common shares were authorized to be delivered in connection with grants under the 2013 Incentive Plan. The common shares to be delivered under the 2013 Incentive Plan are to consist of either common shares currently held or common shares subsequently acquired by Park as treasury shares, including common shares purchased in the open market or in private transactions. As of June 30, 2017, there were 119,587 common shares subject to performance-based restricted stock units (“PBRSUs”) issued under the 2013 Incentive Plan. The Park National Corporation 2017 Long-Term Incentive Plan for Employees (the "2017 Employees LTIP") was adopted by the Board of Directors of Park on January 23, 2017 and was approved by Park's shareholders at the Annual Meeting of Shareholders on April 24, 2017. The 2017 Employees LTIP makes equity-based awards and cash-based awards available for grant to participants in the form of incentive stock options, nonqualified stock options, SARs, Restricted Stock, Restricted Stock Units, Other Stock-Based Awards and cash-based awards. Under the 2017 Employees LTIP, 750,000 common shares are authorized to be delivered in connection with grants under the 2017 Employees LTIP. The common shares to be delivered under the 2017 Employees LTIP are to consist of either common shares currently held or common shares subsequently acquired by Park as treasury shares, including common shares purchased in the open market or in private transactions.

Loan Servicing	Loan Servicing Park serviced sold mortgage loans of $1.35 billion at June 30, 2017 , $1.33 billion at December 31, 2016 and $1.29 billion at June 30, 2016 . At June 30, 2017 , $3.4 million of the sold mortgage loans were sold with recourse, compared to $4.1 million at December 31, 2016 and $4.5 million at June 30, 2016 . Management closely monitors the delinquency rates on the mortgage loans sold with recourse. At June 30, 2017 and December 31, 2016, management had established reserves of $301,000 and $266,000 , respectively, to account for expected losses on 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 mortgage servicing rights (“MSRs”) is assessed for impairment with a comparison to fair value. MSRs are carried at the lower of their amortized cost or fair value. Activity for MSRs and the related valuation allowance follows: Three Months Ended Six Months Ended (In thousands) 2017 2016 2017 2016 Mortgage servicing rights: Carrying amount, net, beginning of period $ 9,321 $ 8,949 $ 9,266 $ 9,008 Additions 521 555 875 871 Amortization (407 ) (415 ) (765 ) (790 ) Changes in valuation allowance 41 (209 ) 100 (209 ) Carrying amount, net, end of period $ 9,476 $ 8,880 $ 9,476 $ 8,880 Valuation allowance: Beginning of period $ 676 $ 542 $ 735 $ 542 Changes in valuation allowance (41 ) 209 (100 ) 209 End of period $ 635 $ 751 $ 635 $ 751 Servicing fees included in other service income were $0.9 million for the three months ended June 30, 2017 and $0.8 million for the same period of 2016 and were $1.8 million for the six months ended June 30, 2017 and $1.7 million for the same period of 2016.

Fair Value Disclosures [Abstract]
Fair Value	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 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 impaired 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 June 30, 2017 using: (In thousands) Level 1 Level 2 Level 3 Balance at June 30, 2017 Assets Investment securities: Obligations of U.S. Treasury and other U.S. Government sponsored entities $ — $ 268,686 $ — $ 268,686 U.S. Government sponsored entities’ asset-backed securities — 923,593 — 923,593 Equity securities 3,378 — 458 3,836 Mortgage loans held for sale — 12,115 — 12,115 Mortgage IRLCs — 223 — 223 Liabilities Fair value swap $ — $ — $ 226 $ 226 Fair Value Measurements at December 31, 2016 using: (In thousands) Level 1 Level 2 Level 3 Balance at December 31, 2016 Assets Investment securities: Obligations of U.S. Treasury and other U.S. Government sponsored entities $ — $ 267,533 $ — $ 267,533 U.S. Government sponsored entities’ asset-backed securities — 987,172 — 987,172 Equity securities 2,644 — 790 3,434 Mortgage loans held for sale — 10,413 — 10,413 Mortgage IRLCs — 124 — 124 Liabilities Fair value swap $ — $ — $ 226 $ 226 There were no transfers between Level 1 and Level 2 during the three months ended June 30, 2017 or 2016 . Management’s policy is to transfer assets or liabilities from one level to another when the methodology to obtain the fair value changes such that there are more or fewer unobservable inputs as of the end of the reporting period. The following methods and assumptions were used by the Company in determining the fair value of the financial assets and liabilities discussed above: Investment securities: Fair values for investment securities are based on quoted market prices, where available. If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments. For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows. 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. Mortgage Interest Rate Lock Commitments (IRLCs): 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 security prices for similar product types and, therefore, are classified in Level 2. The tables below are a reconciliation of the beginning and ending balances of the Level 3 inputs for the three and six months ended June 30, 2017 and 2016 , for financial instruments measured on a recurring basis and classified as Level 3: Level 3 Fair Value Measurements Three months ended June 30, 2017 and 2016 (In thousands) Equity Securities Fair value swap Balance at April 1, 2017 $ 776 $ (226 ) Total gains/(losses) Transfers out of Level 3 (1) (330 ) — Included in other comprehensive income 12 — Balance at June 30, 2017 $ 458 $ (226 ) Balance at April 1, 2016 $ 813 $ (226 ) Total gains/(losses) Included in other comprehensive income 8 — Balance at June 30, 2016 $ 821 $ (226 ) (1) Transfered from Level 3 to Level 1 as the result of a quoted market price becoming available.

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 described below: Impaired Loans: At the time a loan is considered impaired, it is valued at the lower of cost or fair value. Collateral dependent impaired loans carried at fair value have been partially charged-off or receive specific allocations of the allowance for loan 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 client’s business, resulting in a Level 3 fair value classification. Impaired loans are evaluated on a quarterly basis for additional impairment and adjusted accordingly. Additionally, updated independent valuations are obtained annually for all impaired loans in accordance with Company policy. Other Real Estate Owned ("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 collateral dependent impaired 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. 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. Collateral dependent impaired loans are carried at fair value if they have been charged down to fair value or if a specific valuation allowance has been established. 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 to the property's value subsequent to the initial measurement.

Other investments: FHLB and FRB stock within "Other investments" are carried at their respective redemption values as it is not practical to calculate their fair values. Additional investments within "Other investments" are carried at their cost basis as these investments do not have a readily determinable fair value and Park does not have the ability to influence the operating or financial decisions of the investee. Loans receivable: For variable-rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values. The fair values for certain mortgage loans (e.g., one-to-four family residential) are based on quoted market prices of similar loans sold in conjunction with securitization transactions, adjusted for differences in loan characteristics. The fair values for other loans are estimated using discounted cash flow analyses, based upon interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. The methods utilized to estimate the fair value do not necessarily represent an exit price. Off-balance sheet instruments: Fair values for Park’s loan commitments and standby letters of credit are based on the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing. The carrying amount and fair value are not material. Deposit liabilities: The fair values disclosed for demand deposits (e.g., interest and non-interest checking, savings, and money market accounts) are, by definition, equal to the amounts payable on demand at the reporting date (i.e., their carrying amounts). The carrying amounts for variable-rate, fixed-term certificates of deposit approximate their fair values at the reporting date. Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities of time deposits. Short-term borrowings: The carrying amounts of federal funds purchased, borrowings under repurchase agreements and other short-term borrowings approximate their fair values. Long-term debt: Fair values for long-term debt are estimated using a discounted cash flow calculation that applies interest rates currently being offered on long-term debt to a schedule of monthly maturities. Subordinated notes: Fair values for subordinated notes are estimated using a discounted cash flow calculation that applies interest rate spreads currently being offered on similar debt structures to a schedule of monthly maturities.
