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 and nine month periods ended September 30, 2015 are not necessarily indicative of the operating results to be anticipated for the fiscal year ending December 31, 2015. 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 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, 2014 from Park’s 2014 Annual Report to Shareholders (“2014 Annual Report”). Certain prior period amounts have been reclassified to conform to the current period presentation. Additionally, prior period financial statements reflect the retrospective application of Accounting Standards Update ("ASU") 2014-01, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects. Park’s significant accounting policies are described in Note 1 of the Notes to Consolidated Financial Statements included in Park’s 2014 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 2014-01- Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects (a consensus of the FASB Emerging Issues Task Force): In January 2014, the Financial Accounting Standards Board (the "FASB") issued ASU 2014-01, Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects (a consensus of the FASB Emerging Issues Task Force). The ASU permits reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense. Additionally, a reporting entity should disclose information that enables users of its financial statements to understand the nature of its investments in qualified affordable housing projects, and the effect of the measurement of its investments in qualified affordable housing projects and the related tax credits on its financial position and results of operations. The new guidance became effective for annual periods, and interim reporting periods within those annual periods, beginning after December 15, 2014. Park adopted this guidance in the first quarter of 2015. The guidance was applied retrospectively to all prior periods presented. The adoption resulted in adjustments to reduce beginning retained earnings, other assets and the prior periods consolidated condensed statements of income. See Note 16 - Investment in Qualified Affordable Housing for further details. ASU 2014-04 - Receivables—Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure (a consensus of the FASB Emerging Issues Task Force): In January 2014, FASB issued ASU 2014-04, Receivables—Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure (a consensus of the FASB Emerging Issues Task Force). The ASU clarifies when an in substance repossession or foreclosure occurs and a creditor is considered to have received physical possession of real estate property collateralizing a consumer mortgage loan. Specifically, the new ASU requires a creditor to reclassify a collateralized consumer mortgage loan to real estate property upon obtaining legal title to the real estate collateral, or the borrower voluntarily conveying all interest in the real estate property to the lender to satisfy the loan through a deed in lieu of foreclosure or similar legal agreement. Additional disclosures are required detailing the amount of foreclosed residential real estate property held by the creditor and the recorded investment in consumer mortgages collateralized by real estate property that are in the process of foreclosure. The new guidance is effective for annual periods, and interim reporting periods within those annual periods, beginning after December 15, 2014. The adoption of this guidance as of January 1, 2015 did not have a material impact on Park's consolidated financial statements, but resulted in additional disclosures. See Note 5 - Other Real Estate Owned ("OREO") . ASU 2014-09 - Revenue from Contracts with Customers (Topic 606): In May 2014, 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. Management is currently evaluating the impact of the adoption of this guidance on Park's consolidated financial statements. ASU 2014-11 - Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures: In June 2014, the FASB issued ASU 2014-11, Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures . The amendments in this ASU change the accounting for repurchase-to-maturity transactions and linked repurchase financings to secured borrowing accounting, which is consistent with the accounting for other repurchase agreements. The amendments also require two new disclosures. The first disclosure requires an entity to disclose information on transfers accounted for as sales in transactions that are economically similar to repurchase agreements. The second disclosure provides increased transparency about the types of collateral pledged in repurchase agreements and similar transactions accounted for as secured borrowings. The accounting changes are effective for annual periods, and interim reporting periods within those annual periods, beginning after December 15, 2014. The disclosure for certain transactions accounted for as a sale is required to be presented for interim and annual periods beginning after December 15, 2014, with all other disclosure requirements required to be presented for annual periods beginning after December 15, 2014, and for interim periods beginning after March 15, 2015. The adoption of this guidance as of January 1, 2015 did not have an impact on Park's consolidated financial statements, but resulted in additional disclosures. See Note 17 - Repurchase Agreement Borrowings . ASU 2015-02 - Consolidation (Topic 810): Amendments to the Consolidation Analysis : In February 2015, the FASB issued ASU 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis. The ASU amends the current consolidation guidance and affects both the variable interest entity and voting interest entity consolidation models. The new guidance is effective for annual reporting periods and interim reporting periods within those annual periods, beginning after December 15, 2015. Early adoption is permitted. Management is currently evaluating the impact of the adoption of this guidance on Park’s consolidated financial statements.

At September 30, 2015 and December 31, 2014 , there were $25.7 million and $32.4 million , respectively, of partial charge-offs on loans individually evaluated for impairment with no related allowance recorded and $4.3 million and $45,000 , 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 of $5.7 million and $3.7 million related to loans individually evaluated for impairment at September 30, 2015 and December 31, 2014 , respectively. These loans with specific reserves had a recorded investment of $26.9 million and $9.3 million as of September 30, 2015 and December 31, 2014 , respectively. Interest income on loans individually evaluated for impairment is recognized on a cash basis only when Park expects to receive the entire recorded investment of the loan.

The remaining are past due nonaccrual loans. Credit Quality Indicators Management utilizes past due information as a credit quality indicator across the loan portfolio. Past due information as of September 30, 2015 and December 31, 2014 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 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 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 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. Certain loans which were modified during the three-month and nine -month periods ended September 30, 2015 and September 30, 2014 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. 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 does 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 as 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. The TDR classification was not removed on any loans during the three -month and nine -month periods ended September 30, 2015 . During the three -month and nine -month periods ended September 30, 2014 , Park removed the TDR classification on $0.9 million and $2.5 million of loans that met the requirements discussed above. At September 30, 2015 and December 31, 2014 , there were $41.9 million and $47.5 million , respectively, of TDRs included in the nonaccrual loan totals. At September 30, 2015 and December 31, 2014 , $19.0 million and $15.7 million of these nonaccrual TDRs were performing in accordance with the terms of the restructured note. As of September 30, 2015 and December 31, 2014 , there were $17.2 million and $16.3 million , respectively, of TDRs included in accruing loan totals. Management will continue to review the restructured loans and may determine it appropriate to move certain of the loans back to accrual status in the future. At September 30, 2015 and December 31, 2014 , Park had commitments to lend $3.3 million and $1.4 million , respectively, of additional funds to borrowers whose outstanding loan terms had been modified in a TDR. The specific reserve related to TDRs at September 30, 2015 and December 31, 2014 was $3.3 million and $2.4 million , respectively. Modifications made in 2014 and 2015 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 $212,000 and $1.2 million were recorded during the three-month and nine -month periods ended September 30, 2015 , respectively, as a result of TDRs identified in 2015. Additional specific reserves of $258,000 and $537,000 were recoded during the three-month and nine -month periods ended September 30, 2014 , respectively, as a result of TDRs identified in 2014. The terms of certain other loans were modified during the nine -month periods ended September 30, 2015 and September 30, 2014 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 September 30, 2015 and September 30, 2014 of $245,000 and $443,000 , respectively. The renewal/modification of these loans: (1) involved a renewal/modification of the terms of a loan to a borrower who was not experiencing financial difficulties, (2) resulted in a delay in a payment that was considered to be insignificant, or (3) resulted in Park obtaining additional collateral or guarantees that improved the likelihood of the ultimate collection of the loan such that the 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 $12.8 million and $17.6 million , as of September 30, 2015 and September 30, 2014 , 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 nine -month periods ended September 30, 2015 and September 30, 2014 , as well as the recorded investment of these contracts at September 30, 2015 and September 30, 2014 . 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 Losses

Allowance For Loan Losses	9 Months Ended

Loans and Leases Receivable, Allowance [Abstract]
Allowance For Loan Losses	Allowance for Loan Losses The allowance for loan losses 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 2014 Annual Report. Management updates historical losses annually in the fourth quarter, or more frequently as deemed appropriate. With the inclusion of 2013 net charge-off information, management concluded that it was no longer appropriate to calculate the historical loss average with an even allocation across the five-year period. Rather than apply a 20% allocation to each year in the calculation of the historical annualized loss factor, management determined that it was appropriate to more heavily weight those years with higher losses in the historical loss calculation, given the continued uncertainty in the current economic environment. Specifically, rather than applying equal percentages to each year in the historical loss calculation, management applied more weight to the 2009-2011 periods compared to the 2012 and 2013 periods. With the inclusion of 2014 net charge-off information in the fourth quarter of 2014, management extended the historical loss period to six years. Due to the same factors that management considered in 2013, management applied more weight to 2009 through 2011 periods compared to the 2012 through 2014 periods. The activity in the allowance for loan losses for the three and nine months ended September 30, 2015 and September 30, 2014 is summarized below.

Transfers and Servicing of Financial Assets [Abstract]
Loan Servicing	Loan Servicing Park serviced sold mortgage loans of $1.27 billion at each of September 30, 2015 , December 31, 2014 and September 30, 2014 . At September 30, 2015 , $5.7 million of the sold mortgage loans were sold with recourse, compared to $7.0 million at December 31, 2014 and $7.6 million at September 30, 2014 . Management closely monitors the delinquency rates on the mortgage loans sold with recourse. At September 30, 2015 and December 31, 2014, management had established reserves of $827,000 and $379,000 , respectively, to account for expected 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 Nine Months Ended (In thousands) 2015 2014 2015 2014 Mortgage servicing rights: Carrying amount, net, beginning of period $ 8,561 $ 8,662 $ 8,613 $ 9,013 Additions 476 275 1,283 713 Amortization (436 ) (421 ) (1,266 ) (1,249 ) Changes in valuation allowance 211 116 182 155 Carrying amount, net, end of period $ 8,812 $ 8,632 $ 8,812 $ 8,632 Valuation allowance: Beginning of period $ 855 $ 992 $ 826 $ 1,031 Changes in valuation allowance (211 ) (116 ) (182 ) (155 ) End of period $ 644 $ 876 $ 644 $ 876 Servicing fees included in other service income were $0.8 million and $2.5 million for the three and nine months ended September 30, 2015, respectively.

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 per 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 September 30, 2015 using: (In thousands) Level 1 Level 2 Level 3 Balance at September 30, 2015 Assets Investment securities: Obligations of U.S. Treasury and other U.S. Government sponsored entities $ — $ 545,051 $ — $ 545,051 U.S. Government sponsored entities’ asset-backed securities — 745,780 — 745,780 Equity securities 1,876 — 757 2,633 Mortgage loans held for sale — 11,403 — 11,403 Mortgage IRLCs — 195 — 195 Liabilities Fair value swap $ — $ — $ 226 $ 226 Fair Value Measurements at December 31, 2014 using: (In thousands) Level 1 Level 2 Level 3 Balance at December 31, 2014 Assets Investment securities: Obligations of U.S. Treasury and other U.S. Government sponsored entities $ — $ 538,064 $ — $ 538,064 U.S. Government sponsored entities’ asset-backed securities — 761,153 — 761,153 Equity securities 1,922 — 776 2,698 Mortgage loans held for sale — 5,264 — 5,264 Mortgage IRLCs — 70 — 70 Liabilities Fair value swap $ — $ — $ 226 $ 226 There were no transfers between Level 1 and Level 2 during the nine months ended September 30, 2015 or 2014 . 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 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): 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 table below is a reconciliation of the beginning and ending balances of the Level 3 inputs for the three and nine months ended September 30, 2015 and 2014 , for financial instruments measured on a recurring basis and classified as Level 3: Level 3 Fair Value Measurements Three months ended September 30, 2015 and 2014 (In thousands) Equity Securities Fair value swap Balance, at July 1, 2015 $ 744 $ (226 ) Total gains/(losses) Included in earnings – realized — — Included in earnings – unrealized — — Included in other comprehensive income (loss) 13 — Purchases, sales, issuances and settlements, other — — Re-evaluation of fair value swap, recorded in other expense — — Balance at September 30, 2015 $ 757 $ (226 ) Balance, at July 1, 2014 $ 747 $ (135 ) Total gains/(losses) Included in earnings – realized — — Included in earnings – unrealized — — Included in other comprehensive income (loss) 14 — Purchases, sales, issuances and settlements, other — — Re-evaluation of fair value swap — (91 ) Balance at September 30, 2014 $ 761 $ (226 ) Level 3 Fair Value Measurements Nine months ended September 30, 2015 and 2014 (In thousands) Equity Securities Fair value swap Balance, at January 1, 2015 $ 776 $ (226 ) Total gains/(losses) Included in earnings – realized — — Included in earnings – unrealized — — Included in other comprehensive income (loss) (19 ) — Purchases, sales, issuances and settlements, other — — Re-evaluation of fair value swap, recorded in other expense — — Balance at September 30, 2015 $ 757 $ (226 ) Balance, at January 1, 2014 $ 759 $ (135 ) Total gains/(losses) Included in earnings – realized — — Included in earnings – unrealized — — Included in other comprehensive income (loss) 2 — Purchases, sales, issuances and settlements, other — — Re-evaluation of fair value swap — (91 ) Balance at September 30, 2014 $ 761 $ (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 described below: Impaired Loans: At the time a loan is considered impaired, it is valued at the lower of cost or fair value. 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 comparable sales 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, real estate appraisals, income approach appraisals, and lot development loan appraisals, received by the Company. 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.

FHLB Stock and FRB Stock: These assets are carried at their respective redemption values as it is not practicable to calculate their fair values. 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 amount 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 debentures and notes: Fair values for subordinated debentures and 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. The fair value of financial instruments at September 30, 2015 and December 31, 2014 , was as follows: September 30, 2015 Fair Value Measurements (In thousands) Carrying value Level 1 Level 2 Level 3 Total fair value Financial assets: Cash and money market instruments $ 382,255 $ 382,255 $ — $ — $ 382,255 Investment securities 1,410,973 1,876 1,410,416 757 1,413,049 Federal Home Loan Bank stock 50,086 N/A N/A N/A N/A Federal Reserve Bank stock 8,225 N/A N/A N/A N/A Accrued interest receivable - securities 4,324 — 4,324 — 4,324 Accrued interest receivable - loans 14,652 — — 14,652 14,652 Loans held for sale 11,403 — 11,403 — 11,403 Mortgage IRLCs 195 — 195 — 195 Impaired loans carried at fair value 12,599 — — 12,599 12,599 Other loans, net 4,917,232 — — 4,916,210 4,916,210 Loans receivable, net $ 4,941,429 $ — $ 11,598 $ 4,928,809 $ 4,940,407 Financial liabilities: Noninterest bearing checking accounts $ 1,288,750 $ 1,288,750 $ — $ — $ 1,288,750 Interest bearing transactions accounts 1,212,244 1,212,244 — — 1,212,244 Savings accounts 1,623,832 1,623,832 — — 1,623,832 Time deposits 1,324,831 — 1,330,003 — 1,330,003 Other 5,325 5,325 — — 5,325 Total deposits $ 5,454,982 $ 4,130,151 $ 1,330,003 $ — $ 5,460,154 Short-term borrowings $ 278,324 $ — $ 278,324 $ — $ 278,324 Long-term debt 736,580 — 778,621 — 778,621 Subordinated debentures/notes 45,000 — 42,847 — 42,847 Accrued interest payable – deposits 1,143 63 1,080 — 1,143 Accrued interest payable – debt/borrowings 1,327 12 1,315 — 1,327 Derivative financial instruments: Fair value swap $ 226 $ — $ — $ 226 $ 226 December 31, 2014 Fair Value Measurements (In thousands) Carrying value Level 1 Level 2 Level 3 Total fair value Financial assets: Cash and money market instruments $ 237,699 $ 237,699 $ — $ — $ 237,699 Investment securities 1,442,477 1,922 1,442,708 775 1,445,405 Federal Home Loan Bank stock 50,086 N/A N/A N/A N/A Federal Reserve Bank stock 8,225 N/A N/A N/A N/A Accrued interest receivable - securities 4,048 — 4,048 — 4,048 Accrued interest receivable - loans 13,629 — — 13,629 13,629 Loans held for sale 5,264 — 5,264 — 5,264 Mortgage IRLCs 70 — 70 — 70 Impaired loans carried at fair value 16,963 — — 16,963 16,963 Other loans, net 4,753,033 — — 4,757,461 4,757,461 Loans receivable, net $ 4,775,330 $ — $ 5,334 $ 4,774,424 $ 4,779,758 Financial liabilities: Noninterest bearing checking accounts $ 1,269,296 $ 1,269,296 $ — — $ 1,269,296 Interest bearing transactions accounts 1,122,079 1,122,079 — — 1,122,079 Savings accounts 1,325,445 1,325,445 — — 1,325,445 Time deposits 1,409,911 — 1,422,885 — 1,422,885 Other 1,269 1,269 — — 1,269 Total deposits $ 5,128,000 $ 3,718,089 $ 1,422,885 $ — $ 5,140,974 Short-term borrowings $ 276,980 $ — $ 276,980 $ — $ 276,980 Long-term debt 786,602 — 827,500 — 827,500 Subordinated debentures/notes 45,000 — 42,995 — 42,995 Accrued interest payable – deposits 1,125 14 1,111 — 1,125 Accrued interest payable – debt/borrowings 1,426 3 1,423 — 1,426 Derivative financial instruments: Fair value swap $ 226 $ — $ — $ 226 $ 226

Equity Method Investments and Joint Ventures [Abstract]
Affordable Housing Program [Text Block]	Investment in Qualified Affordable Housing Park makes certain equity investments in various limited partnerships that sponsor affordable housing projects. The purpose of these investments is to achieve a satisfactory return on capital, help create affordable housing opportunities, and to assist the Company to achieve our goals associated with the Community Reinvestment Act. Previously, these investments were accounted for under the cost method of accounting with amortization of the investment being recorded in miscellaneous other expense and tax benefits recognized in the provision for income taxes. During the first quarter of 2015, Park adopted ASU 2014-01, Accounting for Investments in Qualified Affordable Housing Projects , and elected the proportional amortization method with amortization expense and tax benefits recognized through the provision for income taxes. This ASU is required to be applied retrospectively to all periods presented. As a result of these changes, Park recorded a cumulative-effect adjustment to beginning retained earnings. The following table summarizes the impact of retrospective application to the balance sheet and income statement for all periods presented as well as the year ended December 31, 2014: (in thousands) December 31, 2014 Other assets As previously reported (which included $45.4 million of affordable housing tax credit investments) $ 140,803 As reported under the new guidance 138,746 Total assets As previously reported $ 7,003,256 As reported under the new guidance 7,001,199 Retained earnings As previously reported $ 486,541 As reported under the new guidance 484,484 Total equity As previously reported $ 698,598 As reported under the new guidance 696,541 (in thousands) 3 months ended September 30, 2014 9 months ended 12 months ended December 31, 2014 Total other expense As previously reported $ 46,903 $ 142,797 $ 195,234 As reported under the new guidance 44,972 136,992 187,510 Income tax expense As previously reported $ 6,398 $ 19,903 $ 28,602 As reported under the new guidance 8,363 25,801 36,459 Net income As previously reported $ 18,303 $ 59,749 $ 84,090 As reported under the new guidance 18,269 59,656 83,957 The table below details the balances of Park’s affordable housing tax credit investments and related unfunded commitments as of September 30, 2015 and December 31, 2014.

Transfers and Servicing [Abstract]
Repurchase Agreement Borrowings	Repurchase Agreement Borrowings Securities sold under agreements to repurchase ("repurchase agreements") with customers represent funds deposited by customers, generally on an overnight basis, that are collateralized by investment securities owned by Park. Repurchase agreements with customers are included in short-term borrowings on the consolidated condensed balance sheets. Park's repurchase agreements with a third-party financial institution are classified as long-term debt on the consolidated condensed balance sheets. All repurchase agreements are subject to terms and conditions of repurchase/security agreements between Park and the client and are accounted for as secured borrowings. Park's repurchase agreements reflected in short-term borrowings consist of customer accounts and securities which are pledged on an individual security basis. At September 30, 2015 and December 31, 2014 , Park's repurchase agreement borrowings totaled $578 million and $577 million , respectively. At both September 30, 2015 and December 31, 2014, $300 million of Park's repurchase agreement borrowings were classified as long-term debt with the remaining amount being classified as short-term debt on the consolidated condensed balance sheets. These borrowings were collateralized with U.S. government and agency securities with a carrying value of $620 million and $664 million at September 30, 2015 and December 31, 2014 , respectively. Declines in the value of the collateral would require Park to pledge additional securities. As of September 30, 2015 and December 31, 2014 , Park had $276 million and $347 million , respectively, of available unpledged securities. The following table presents the carrying value of Park's repurchase agreements by remaining contractual maturity at September 30, 2015 and December 31, 2014 : September 30, 2015 (in thousands) Remaining Contractual Maturity of the Agreements Overnight and Continuous Up to 30 days 30 - 90 days Greater than 90 days Total U.S. government and agency securities $ 271,699 $ 1,140 $ 1,880 $ 303,605 $ 578,324 December 31, 2014 (in thousands) Remaining Contractual Maturity of the Agreements Overnight and Continuous Up to 30 days 30 - 90 days Greater than 90 days Total U.S. government and agency securities $ 268,427 $ 164 $ 4,940 $ 303,449 $ 576,980 On November 30, 2012, Park restructured $300 million in repurchase agreements with a third-party financial institution and paid a $25 million prepayment penalty. The penalty is included in long-term debt and is being amortized as an adjustment to interest expense over the remaining term of the repurchase agreements using the effective interest method. Of the $25 million prepayment penalty, $11.1 million and $14.8 million remained unamortized as of September 30, 2015 and December 31, 2014, respectively.
