PARK NATIONAL CORPORATION

NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

Note 1 – 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, 2018 are not necessarily indicative of the operating results to be anticipated for the fiscal year ending December 31, 2018.

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, 2017 from Park’s 2017 Annual Report to Shareholders (“Park's 2017 Annual Report”). Prior period financial statement reflect the retrospective application of Accounting Standards Update ("ASU") 2017-07 - Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This change in classification had no effect on reported net income.

Park’s significant accounting policies are described in Note 1 of the Notes to Consolidated Financial Statements included in Park’s 2017 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.

Note 2 - 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 issued but not yet effective accounting standards:

Adoption of New Accounting Pronouncements

ASU 2014-09 - Revenue from Contracts with Customers (Topic 606): In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). This 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. The majority of the Company's revenues come from interest income and other sources, including loans, leases, securities and derivatives, that are outside the scope of ASC 606. Certain services that fall within the scope of ASC 606 are presented within Other Income and are recognized as revenue as the Company satisfies its obligation to the customer. Services within the scope of ASC 606 include income from fiduciary activities, service charges on deposit accounts, other service income, checkcard fee income, ATM fees, and gain on sale of OREO, net. The adoption of this guidance on January 1, 2018 did not have a material impact on Park's consolidated financial statements. However, the adoption of this standard resulted in additional disclosures beginning with the first quarter 2018 Form 10-Q. Reference Note 19, Revenue from Contracts with Customers, for further discussion on the Company's accounting policies for revenue sources within the scope of ASC 606.

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 reflected in 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, this ASU clarifies guidance related to the

10

valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale ("AFS") 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 on January 1, 2018 resulted in an $1.9 million increase to beginning retained earnings and a $995,000 increase to beginning accumulated other comprehensive loss. Additional income of $3.2 million and $1.3 million was recorded in the first and second quarters of 2018, respectively, as a result of changes to the accounting for equity investments. Further, beginning with the first quarter of 2018, Park's fair value disclosures in Note 14, Fair Value, have incorporated the revised disclosure requirements for financial investments.

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 then current GAAP was either unclear or did 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.  The adoption of this guidance on January 1, 2018 did not have an impact on Park's consolidated financial statements. As such transactions arise, management will utilize the updated guidance in providing disclosures within Park’s consolidated condensed statements of cash flows. 

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. As a result of the adoption of this guidance on January 1, 2018, all prior periods have been recast to separately record the service cost component and other components of net benefit cost. For all periods presented, this resulted in an increase in other income and an offsetting increase in other expense with no change to net income. See Note 12, Benefit Plans, for further details.

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 concerning which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting under Topic 718. 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 on January 1, 2018 did not impact Park's consolidated financial statements.

ASU 2017-12 - Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities: In August 2017, the FASB issued ASU 2017-12 - Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. This ASU amends the current guidance with the objective of improving the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities in its financial statements. In addition, this ASU amends the current guidance to simplify the application of the hedge accounting guidance. 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 early adoption of this guidance on July 1, 2018 did not have an impact on Park's consolidated financial statements. Park will apply this guidance to future transactions.

ASU 2018-02 - Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income: In February 2018, the FASB issued ASU 2018-02 -Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This ASU allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects, resulting from the newly - enacted federal corporate income tax rate. The amount of the reclassification is the difference between the historical federal corporate income tax rate and the newly-enacted 21% federal corporate income tax rate. The 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 early adoption of this guidance effective January 1, 2018 resulted in a $3.8 million increase to Park's accumulated other comprehensive loss and a $3.8 million increase to retained earnings.

ASU 2018-03 - Technical Corrections and Improvements to Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. In February 2018, the FASB issued ASU 2018-03 - Technical Corrections and Improvements to Financial Instruments - Overall (Subtopic 825-10): Recognition and

11

Measurement of Financial Assets and Financial Liabilities. This ASU includes amendments that clarify certain aspects of the guidance issued in ASU 2016-01. Park considered this clarification in determining the appropriate adoption of ASU 2016-01 effective as of January 1, 2018.

Issued But Not Yet Effective Accounting Standards

ASU 2016-02 - Leases (Topic 842): In February 2016, the FASB issued ASU 2016-02 - Leases (Topic 842). This 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 2016-13 - 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 ("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 model requires an entity to estimate 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 the CECL model and is currently in the process of implementing a software solution to assist in implementing the adoption of this ASU. Management plans to run our current allowance model and a CECL model concurrently for 12 months prior to the adoption of this guidance on January 1, 2020.

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.

Management’s general practice is to proactively charge down loans individually evaluated for impairment to the fair value of the underlying collateral. At June 30, 2018 and December 31, 2017, there were $9.2 million and $7.9 million, respectively, of partial charge-offs on loans individually evaluated for impairment with no related allowance recorded. At June 30, 2018 and December 31, 2017, there were $2.2 million and $2.1 million, respectively, of partial charge-offs on loans individually evaluated for impairment that also had a specific reserve allocated.

15

The allowance for loan losses included specific reserves related to loans individually evaluated for impairment at June 30, 2018 and December 31, 2017 of $1.4 million and $0.7 million, respectively. These loans with specific reserves had a recorded investment of $5.3 million and $3.5 million as of June 30, 2018 and December 31, 2017, 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. The following table presents the average recorded investment and interest income recognized subsequent to impairment on loans individually evaluated for impairment as of and for the three and six months ended June 30, 2018 and June 30, 2017:

Credit Quality Indicators

Management utilizes past due information as a credit quality indicator across the loan portfolio. Past due information as of June 30, 2018 and December 31, 2017 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 a 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.

The tables below present the recorded investment by loan grade at June 30, 2018 and December 31, 2017 for all commercial loans:

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 three-month periods ended June 30, 2018 and June 30, 2017 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. The TDR classification was removed on $1.9 million of loans during the three-month period ended June 30, 2018 and $2.2 million of loans during the six-month period ended June 30, 2018. There were no TDR classifications removed during the three-month or six-month periods ended June 30, 2017.

At June 30, 2018 and December 31, 2017, there were $23.9 million and $38.5 million, respectively, of TDRs included in the nonaccrual loan totals. At June 30, 2018 and December 31, 2017, $18.1 million and $32.4 million, respectively, of these nonaccrual TDRs were performing in accordance with the terms of the restructured note. As of June 30, 2018 and December 31, 2017, loans with a recorded investment of $16.4 million and $20.2 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 June 30, 2018 and December 31, 2017, Park had commitments to lend $0.6 million and $1.3 million, respectively, of additional funds to borrowers whose outstanding loan terms had been modified in a TDR.

19

At both June 30, 2018 and December 31, 2017, there were $0.5 million of specific reserves related to TDRs. Modifications made in 2017 and 2018 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. There were no additional specific reserves recorded during the three-month period ended June 30, 2018 as a result of TDRs identified in the period. Additional specific reserves of $10,000 were recorded during the three-month period ended June 30, 2017 as a result of TDRs identified in the period. Additional specific reserves of $10,000 and $290,000 were recorded during the six-month periods ended June 30, 2018 and June 30, 2017, respectively, as a result of TDRs identified in the respective periods.

The terms of certain other loans were modified during the three-month and six-month periods ended June 30, 2018 and June 30, 2017 that did not meet the definition of a TDR. Substandard commercial loans modified during the three-month and six-month periods ended June 30, 2018 which did not meet the definition of a TDR had a total recorded investment of $0.1 million and $0.2 million, respectively. There were no substandard commercial loans modified during the three-month period ended June 30, 2017 which did not meet the definition of a TDR. Substandard commercial loans with a recorded investment of $0.1 million were modified during the six-month period ended June 30, 2017 which did not meet the definition of a TDR. 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. Consumer loans modified during the three-month and six-month periods ended June 30, 2018 which did not meet the definition of a TDR had a total recorded investment of $4.7 million and $11.0 million, respectively. Consumer loans with a recorded investment of $3.4 million and $5.0 million were modified during the three-month and six-month periods ended June 30, 2017 and did not meet the definition of a TDR. 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 periods ended June 30, 2018 and June 30, 2017, as well as the recorded investment of these contracts at June 30, 2018 and June 30, 2017. The recorded investment pre- and post-modification is generally the same due to the fact that Park does not typically forgive principal.

Note 4 – 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 2017 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 following are factors management reviews on a quarterly or annual basis.

• Historical Loss Factor: Management updated the historical loss calculation during the fourth quarter of 2017, incorporating net charge-offs plus changes in specific reserves through December 31, 2017.  With the addition of 2017 historical losses, management extended the historical loss period to 96 months from 84 months. The 96-month historical loss period captures all annual periods subsequent to June 2009, the end of the most recent recession, thus encompassing the full economic cycle to date.

• Loss Emergence Period Factor: At least annually, management calculates the loss emergence period for each commercial loan segment. This loss emergence period is calculated based upon the average period of time it takes from the probable occurrence of a loss event to the credit being moved to nonaccrual. If the loss emergence period for any commercial loan segment is greater than one year, management applies additional general reserves to all performing loans within that segment of the commercial loan portfolio. The loss emergence period was last updated in the fourth quarter of 2017.

• Loss Migration Factor: Park’s commercial loans are individually risk graded. If loan downgrades occur, the probability of default increases, and accordingly, management allocates a higher percentage reserve to those accruing commercial loans graded special mention and substandard. Annually, management calculates a loss migration factor for each commercial loan segment for special mention and substandard credits based on a review of losses over the period of time a loan takes to migrate from pass-rated to impaired. The loss migration factor was last updated in the fourth quarter of 2017.

23

• Environmental Loss Factor:Management has identified certain macroeconomic factors that trend in accordance with losses in Park’s commercial loan portfolio. These macroeconomic factors are reviewed quarterly and the adjustments made to the environmental loss factor impacting each segment in the performing commercial loan portfolio correlate to changes in the macroeconomic environment. There was no change to the environmental loss factor during the second quarter of 2018.

The activity in the allowance for loan losses for the three-month and six-month periods ended June 30, 2018 and June 30, 2017 is summarized in the following tables.

Loans collectively evaluated for impairment in the following tables include all performing loans at June 30, 2018 and December 31, 2017, as well as nonperforming loans internally classified as consumer loans. Nonperforming consumer loans are not typically individually evaluated for impairment, but receive a portion of the statistical allocation of the allowance for loan losses. Loans individually evaluated for impairment include all impaired loans internally classified as commercial loans at June 30, 2018 and December 31, 2017, which are evaluated for impairment in accordance with U.S. GAAP (see Note 1 of the Notes to Consolidated Financial Statements included in Park’s 2017 Annual Report).

Park has entered into Supplemental Executive Retirement Plan Agreements (the “SERP Agreements”) with certain key officers of the Corporation and its subsidiaries which provide defined pension benefits in excess of limits imposed by federal tax law. The expense for the Corporation related to the SERP Agreements for the three months and six months ended June 30, 2018 and 2017 was as follows:

	Three Months Ended June 30,				Six Months Ended June 30,				Affected Line Item in the Consolidated Condensed Statement of Income
(In thousands)	2018		2017		2018		2017

Interest cost	44		161		161		322		Miscellaneous expense
Total SERP expense	$	288	$	346	$	639	$	692

Previously, the net periodic benefit income/expense related to Park’s Pension and the expense related to the SERP Agreements had been recorded within the "Employee benefits" line item.

During the first quarter of 2018, Park adopted ASU 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement. 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. This ASU is required to be applied retrospectively to all periods presented. For all periods presented, this resulted in an increase in other income and an offsetting increase in other expense with no change to net income. As a practical expedient, Park used the amounts disclosed in "Note 12 - Pension Plan" of the Notes to Unaudited Consolidated Condensed Financial Statements, included under Item 1 of Part I of Park's Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2017 as the estimation basis for applying the retrospective presentation requirements.

The following table summarizes the impact of retrospective application of this ASU to the consolidated condensed statement of income for the three and six months ended June 30, 2017.

Note 13 – Loan Servicing

Park serviced sold mortgage loans of $1.38 billion at June 30, 2018, $1.37 billion at December 31, 2017 and $1.35 billion at June 30, 2017. At June 30, 2018, $2.6 million of the sold mortgage loans were sold with recourse, compared to $3.0 million at December 31, 2017 and $3.4 million at June 30, 2017. Management closely monitors the delinquency rates on the mortgage loans sold with recourse. At June 30, 2018 and December 31, 2017, management had established reserves of $43,000 and $270,000, respectively, to account for expected losses on loan repurchases.

When Park sells mortgage loans with servicing rights retained, these 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 with respect to 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. The amortization of MSRs is included within other service income in the consolidated condensed statements of income.

Note 14 – 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 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.

There were no transfers between Level 1 and Level 2 during either of the three months ended June 30, 2018 or 2017. 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 (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.

Mortgage Interest Rate Lock Commitments (IRLCs): Mortgage IRLCs are based on current secondary market pricing and are classified as Level 2.

37

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 presents a reconciliation of the beginning and ending balances of the Level 3 inputs for the three and six months ended June 30, 2018 and 2017, for financial instruments measured on a recurring basis and classified as Level 3:

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.

38

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.

The expense from credit adjustments related to impaired loans carried at fair value during the three months ended June 30, 2018 and 2017 was $0.2 million and $0.1 million, respectively. The expense from credit adjustments related to impaired loans carried at fair value during the six months ended June 30, 2018 and 2017 was $0.3 million and $0.5 million, respectively.

MSRs totaled $10.1 million at June 30, 2018. Of this $10.1 million MSR carrying balance, $0.9 million was recorded at fair value and included a valuation allowance of $0.2 million. The remaining $9.2 million was recorded at cost, as the fair value of the MSRs exceeded cost at June 30, 2018. At December 31, 2017, MSRs totaled $9.7 million. Of this $9.7 million MSR carrying balance, $7.3 million was recorded at fair value and included a valuation allowance of $0.6 million. The remaining $2.4 million was recorded at cost, as the fair value exceeded cost at December 31, 2017. The income related to MSRs carried at fair value during the three months ended June 30, 2018 and 2017 was $77,000 and $41,000, respectively. The income related to MSRs carried at fair value during the six months ended June 30, 2018 and 2017 was $382,000 and $100,000, respectively.

Total OREO held by Park at June 30, 2018 and December 31, 2017 was $5.7 million and $14.2 million, respectively. Approximately 75% and 46% of OREO held by Park at June 30, 2018 and December 31, 2017, respectively, was carried at fair value due to fair value adjustments made subsequent to the initial OREO measurement. At June 30, 2018 and December 31,

40

2017, OREO held at fair value, less estimated selling costs, amounted to $4.3 million and $6.5 million, respectively. The net expense related to OREO fair value adjustments was $114,000 and $272,000 for the three-month periods ended June 30, 2018 and 2017, respectively. The net expense related to OREO fair value adjustments was $321,000 and $345,000 for the six-month periods ended June 30, 2018 and 2017, respectively.

Assets Measured at Net Asset Value:

The adoption of ASU 2016-01 on January 1, 2018 required Park to evaluate the accounting for equity investments, including those previously held at cost. Under the new guidance, Park determined that its portfolio of equity investments in limited partnerships which provide mezzanine funding ("Partnership Investments") should be valued using the net asset value ("NAV") practical expedient in accordance with ASC 820. The adoption of this guidance on January 1, 2018, resulted in a $1.2 million increase to Partnership Investments, which are included within other assets on the consolidated condensed balance sheet, and a $922,000 increase to beginning retained earnings.

As of June 30, 2018 and December 31, 2017, Park had Partnerships Investments with a NAV of $9.4 million and $8.8 million, respectively. As of June 30, 2018 and December 31, 2017, Park had $7.1 million and $7.2 million in unfunded commitments related to these Partnership Investments. For the six months ended June 30, 2018, Park had recognized $752,000 in income related to these Partnership Investments.

Note 17 – 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.

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 consisted of customer accounts and securities which are pledged on an individual security basis.

At June 30, 2018 and December 31, 2017, Park's repurchase agreement borrowings totaled $165 million and $183 million, respectively. These borrowings were collateralized with U.S. government and agency securities with a carrying value of $198 million and $213 million at June 30, 2018 and December 31, 2017, respectively. Declines in the value of the collateral would require Park to pledge additional securities. As of June 30, 2018 and December 31, 2017, Park had $961 million and $975 million, respectively, of available unpledged securities.

The table below shows the remaining contractual maturity of repurchase agreements by collateral pledged at June 30, 2018 and December 31, 2017:

The Company is a defendant in lawsuits and other adversary proceedings arising in the ordinary course of business. Legal costs incurred in connection with the resolution of claims and lawsuits are generally expensed as incurred, and the Company establishes accruals for the outcome of litigation where losses are deemed probable and reasonably estimable. The Company’s assessment of the current exposure could change in the event of the discovery of additional facts with respect to legal matters

46

pending against the Company or determinations by judges, juries, administrative agencies or other finders of fact that are not in accordance with the Company’s evaluation of claims.

As of June 30, 2017, the Company had accrued charges of approximately $2.3 million for legal contingencies related to various legal and other adversary proceedings.  This amount was paid out in full settlement of the related litigation during the three months ended September 30, 2017.  As of June 30, 2018, the Company had accrued charges of $20,000 for legal contingencies related to various legal and other adversary proceedings.

Note 19 - Revenue from Contracts with Customers

The Company adopted ASC 606 using the modified retrospective method applied to all contracts not completed as of January 1, 2018.  Results for reporting periods beginning on and after January 1, 2018 are presented under ASC 606 while prior period amounts continue to be reported in accordance with legacy GAAP.  The adoption of ASC 606 did not result in a change to the accounting for any of the in-scope revenue streams; as such, no cumulative effect adjustment was recorded. 

All of Park's revenue from contracts with customers within the scope of ASC 606 is recognized within "Other income" in the Consolidated Condensed Statements of Income. The following table presents the Corporation's sources of other income by revenue stream and operating segment for the three-month and six-month periods ended June 30, 2018 and June 30, 2017.

⁽⁴⁾ The Corporation elected the modified retrospective approach of adoption; therefore, prior period balances are presented under legacy GAAP and may not be comparable to current year presentation.

A description of Park's 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 its 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, 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. These fees are generally recognized at a point in time following the completion of a loan sale or related service activity.

50

Checkcard 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 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 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.

Note 20- Subsequent Events

On July 1, 2018, NewDominion Bank, a North Carolina state-chartered bank (“NewDominion”), merged with and into PNB, with PNB continuing as the surviving entity pursuant to the Agreement and Plan of Merger and Reorganization, dated as of January 22, 2018, by and among Park, PNB, and NewDominion. As of June 30, 2018, NewDominion had approximately $329 million in total assets, $278 million in total loans, and $284 million in total deposits. The acquisition was valued at approximately $79 million and resulted in Park issuing approximately 435,457 Park common shares and paying approximately $31 million in cash in exchange for the NewDominion common stock as merger consideration.

The assets and liabilities of NewDominion will be recorded on Park’s consolidated balance sheet at their preliminary estimated fair values as of July 1, 2018, the acquisition date, and NewDominion’s results of operations will be included in Park’s consolidated statement of income from that date. The initial accounting and determination of the fair values of the assets acquired and liabilities assumed in the acquisition was incomplete at the time of the filing of Park’s Quarterly Report on From 10-Q for the quarterly period ended June 30, 2018 (the “June 30, 2018 Form 10-Q”) due to the timing of the closing of the acquisition in relation to the deadline for the filing of Park’s June 30, 2018 Form 10-Q. A more complete disclosure of the business combination is expected to be reported in Park’s Quarterly Report on Form 10-Q for the quarterly period ending September 30, 2018.

For the six months ended June 30, 2018, Park recorded merger-related expenses of $0.5 million associated with the NewDominion acquisition.

ITEM 2 – MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL

CONDITION AND RESULTS OF OPERATIONS

Management’s discussion and analysis (“MD&A”) contains forward-looking statements that are provided to assist in the understanding of anticipated future financial performance. Forward-looking statements provide current expectations or forecasts of future events and are not guarantees of future performance.  The forward-looking statements are based on management’s expectations and are subject to a number of risks and uncertainties.  Although management believes that the expectations reflected in such forward-looking statements are reasonable, actual results may differ materially from those expressed or implied in such statements.  Risks and uncertainties that could cause actual results to differ materially include, without limitation: Park's ability to execute our business plan successfully and within the expected timeframe; general economic and financial market conditions, specifically in the real estate markets and the credit markets, either nationally or in the states in which Park and our subsidiaries do business, may experience a slowing or reversal of the recent economic expansion in addition to continuing residual effects of recessionary conditions and an uneven spread of positive impacts of recovery on the economy and our counterparties, resulting in adverse impacts on the demand for loan, deposit and other financial services, delinquencies, defaults and counterparties' ability to meet credit and other obligations; changes in interest rates and prices may adversely impact prepayment penalty income, mortgage banking income, the value of securities, loans, deposits and other financial instruments and the interest rate sensitivity of our consolidated balance sheet as well as reduce interest margins and impact loan demand; changes in consumer spending, borrowing and saving habits, whether due to the newly-enacted tax reform legislation, changing business and economic conditions, legislative and regulatory initiatives, or other factors; changes in unemployment; changes in customers', suppliers', and other counterparties' performance and creditworthiness; asset/liability repricing risks and liquidity risks; our liquidity requirements could be adversely affected by changes to regulations governing bank and bank holding company capital and liquidity standards as well as by changes in our assets and liabilities; competitive factors among financial services organizations could increase significantly, including product and pricing pressures, changes to third-party relationships and our ability to attract, develop and retain qualified bank professionals; clients could pursue alternatives to bank deposits, causing us to lose a relatively inexpensive source of funding;

51

uncertainty regarding the nature, timing, cost and effect of changes in banking regulations or other regulatory or legislative requirements affecting the respective businesses of Park and our subsidiaries, including major reform of the regulatory oversight structure of the financial services industry and changes in laws and regulations concerning taxes, pensions, bankruptcy, consumer protection, rent regulation and housing, financial accounting and reporting, environmental protection, insurance, bank products and services, bank capital and liquidity standards, fiduciary standards, securities and other aspects of the financial services industry, specifically the reforms provided for in the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”) and the Basel III regulatory capital reforms, as well as regulations already adopted and which may be adopted in the future by the relevant regulatory agencies, including the Consumer Financial Protection Bureau, the Office of the Comptroller of the Currency, the Federal Deposit Insurance Corporation, and the Federal Reserve Board, to implement the Dodd-Frank Act's provisions, and the Basel III regulatory capital reforms; the effect of changes in accounting policies and practices, as may be adopted by the Financial Accounting Standards Board, the SEC, the Public Company Accounting Oversight Board and other regulatory agencies, and the accuracy of our assumptions and estimates used to prepare our financial statements; changes in law and policy accompanying the current presidential administration, including the recently-enacted Tax Cuts and Jobs Act, and uncertainty or speculation pending the enactment of such changes; uncertainties in Park's preliminary review of, and additional analysis of, the impact of the Tax Cuts and Jobs Act; the effect of healthcare laws in the United States and potential changes for such laws which may increase our healthcare and other costs and negatively impact our operations and financial results;

Critical Accounting Policies

Note 1 of the Notes to Consolidated Financial Statements included in Park’s 2017 Annual Report lists significant accounting policies used in the development and presentation of Park’s consolidated financial statements. The accounting and reporting policies of Park conform with U.S. GAAP and general practices within the financial services industry. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and the accompanying notes. Actual results could differ from those estimates.

Park believes the determination of the allowance for loan losses involves a higher degree of judgment and complexity than its other significant accounting policies. The allowance for loan losses is calculated with the objective of maintaining a reserve level believed by management to be sufficient to absorb probable incurred credit losses in the loan portfolio. Management’s determination of the adequacy of the allowance for loan losses is based on periodic evaluations of the loan portfolio and of current economic conditions. However, this evaluation has subjective components requiring material estimates, including expected default probabilities, the expected loss given default, the amounts and timing of expected future cash flows on impaired loans, and estimated losses on consumer loans and residential mortgage loans based on historical loss experience and current economic conditions. All of these factors may be susceptible to significant change. To the extent that actual results differ from management estimates, additional loan loss provisions may be required that would adversely impact earnings in future periods. Refer to the “Credit Metrics and Provision for (Recovery of) Loan Losses” section within this MD&A for additional discussion.

Other real estate owned (“OREO”), property acquired through foreclosure, is recorded at estimated fair value less anticipated selling costs (net realizable value). If the net realizable value is below the carrying value of the loan on the date of transfer, the difference is charged to the allowance for loan losses. Subsequent declines in value, OREO devaluations, are reported as adjustments to the carrying amount of OREO and are expensed within other income. Gains or losses not previously recognized, resulting from the sale of OREO, are recognized within other income on the date of sale.

U.S. GAAP requires management to establish a fair value hierarchy, which has the objective of maximizing the use of observable market inputs. U.S. GAAP also requires enhanced disclosures regarding the inputs used to calculate fair value. These are classified as Level 1, Level 2, and Level 3. Level 3 inputs are those with significant unobservable inputs that reflect a company’s own assumptions about the market for a particular instrument. Some of these inputs could be based on internal models and cash flow analyses. The large majority of Park’s assets whose fair value is determined using Level 2 inputs consists of AFS securities. The fair value of these AFS securities is obtained largely through the use of matrix pricing, which is a mathematical technique widely used in the financial services industry to value debt securities without relying exclusively on quoted market prices for the specific securities but rather relying on the securities’ relationship to other benchmark quoted securities. Please see Note 14 - Fair Value of the Notes to Unaudited Consolidated Condensed Financial Statements in this Quarterly Report on Form 10-Q for additional information on fair value.

Management believes that the accounting for goodwill also involves a higher degree of judgment than most other significant accounting policies. U.S. GAAP establishes standards for the impairment assessment of goodwill. Goodwill arising from business combinations represents the value attributable to unidentifiable intangible assets in the business acquired. Park’s goodwill, as of June 30, 2018, relates to the value inherent in the banking industry and that value is dependent upon the ability of Park’s Ohio-based national bank subsidiary, The Park National Bank (“PNB”) to provide quality, cost-effective banking services in a competitive marketplace. The goodwill value is supported by revenue that is in part driven by the volume of business transacted. A decrease in earnings resulting from a decline in the customer base, the inability to deliver cost-effective services over sustained periods or significant credit problems can lead to impairment of goodwill that could adversely impact earnings in future periods. U.S. GAAP requires an annual evaluation of goodwill for impairment, or more frequently if events or changes in circumstances indicate that the asset might be impaired. Park’s most recent evaluation was completed during the second quarter of 2018 and resulted in no impairment of goodwill. Further, there have been no events subsequent to that analysis that provide any evidence that goodwill is impaired. The fair value of the goodwill, which resides on the books of PNB, is estimated by reviewing the past and projected operating results for PNB, deposit and loan totals for PNB and banking industry comparable information.

The determination of pension plan obligations and related expenses requires the use of assumptions to estimate the amount of benefits that employees earn while working, as well as the present value of those benefits. Annual pension expense is principally based on four components: (1) the value of benefits earned by employees for working during the year (service cost), (2) the increase in the liability due to the passage of time (interest cost), and (3) other gains and losses, reduced by (4) the expected return on plan assets for our pension plan.

53

Significant assumptions used to measure our annual pension expense include:

• the interest rate used to determine the present value of liabilities (discount rate);

• certain employee-related factors, such as turnover, retirement age and mortality;

• the expected return on assets in our funded plan; and

• for pension expense, the rate of salary increases where benefits are based on earnings.

Our assumptions reflect our historical experience and management’s best judgment regarding future expectations. Due to the significant management judgment involved, our assumptions could have a material impact on the measurement of our pension plan expense and obligation.

Comparison of Results of Operations

For the Three and Six Months Ended June 30, 2018 and 2017

Summary Discussion of Results

Net income for the three months ended June 30, 2018 was $28.2 million, compared to $19.0 million for the second quarter of 2017. Diluted earnings per common share were $1.83 for the second quarter of 2018, compared to $1.24 for the second quarter of 2017. Weighted average diluted common shares outstanding were 15,417,607 for the second quarter of 2018, compared to 15,398,865 weighted average diluted common shares outstanding for the second quarter of 2017.

Net income for the six months ended June 30, 2018 was $59.4 million, compared to $39.3 million for the six months ended June 30, 2017. Diluted earnings per common share were $3.85 for the first six months of 2018, compared to $2.55 for the first six months of 2017. Weighted average diluted common shares outstanding were 15,424,585 for the first six months of 2018, compared to 15,415,765 weighted average diluted common shares outstanding for the first six months of 2017.

During the first quarter of 2018, Park adopted ASU 2017-07, 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 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.  This ASU is required to be applied retrospectively to all periods presented.  As a result of the adoption of this ASU, all prior periods have been recast to separately record the service cost component and other components of net benefit cost.  For Park, this resulted in an increase in other income and an offsetting increase in other expense with no change to net income.

During the first quarter of 2018, Park adopted ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. Changes reflected in 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. As a result of the adoption of this ASU, Park recorded an increase of $1.9 million to beginning retained earnings and a $995,000 increase to beginning accumulated other comprehensive loss. Additional income of $3.2 million and $1.3 million was recorded in other income in the first and second quarters of 2018, respectively, as the result of changes to the accounting for equity investments.

Net income	$	28,797	$	26,745		$	55,542	$	41,649	$	87,315	$	84,451

Net interest income of $124.1 million for the six months ended June 30, 2018 represented a $8.8 million, or 7.7%, increase compared to $115.3 million for the six months ended June 30, 2017. The increase was the result of a $7.6 million increase in interest income and a $1.2 million decrease in interest expense.

The $7.6 million increase in interest income was due to a $6.2 million increase in interest income on loans, along with a $1.4 million increase in interest income on investments. The increase in interest income on loans was the result of higher yields on loans. The yield on loans was 4.74% for the six months ended June 30, 2018, compared to 4.53% for the six months ended June 30, 2017. Included in interest income for the six months ended June 30, 2018 was $817,000 in interest income, related to PNB participations in legacy Vision Bank ("Vision") assets.

The $1.2 million decrease in interest expense was due to a $4.3 million increase in interest expense on deposits offset by a $5.5 million decrease in interest expense on borrowings. The increase in interest expense on deposits was partially the result of a $87.9 million, or 2.0%, increase in average interest-bearing deposits from $4.29 billion for the six months ended June 30, 2017, to $4.37 billion for the six months ended June 30, 2018. Additionally, the cost of deposits increased by 19 basis points from 0.40% for the six months ended June 30, 2017 to 0.59% for the six months ended June 30, 2018. The decrease in interest expense on borrowings was the result of a decrease in long-term debt. During the fourth quarter of 2017, Park utilized excess cash to repay $350 million of long-term debt which matured during November 2017. The effective interest rate on the repaid long-term debt had been 3.22%.

The provision for loan losses of $1.6 million for the six months ended June 30, 2018 represented a decrease of $3.7 million, compared to $5.3 million for the six months ended June 30, 2017. Refer to the “Credit Metrics and Provision for (Recovery of) Loan Losses” section for additional details regarding the level of the provision for (recovery of) loan losses recognized in each period presented above.

Other income of $42.0 million for the six months ended June 30, 2018 represented an increase of $2.3 million, or 5.8%, compared to $39.7 million for the six months ended June 30, 2017. The $2.3 million increase was primarily related to a $1.3 million increase in gains on sale of OREO, net, a $1.5 million increase in fiduciary income, a $486,000 increase in gains on sale of assets, net, a $498,000 increase in other components of net periodic pension benefit income, a $339,000 increase in other service income, and a $583,000 increase in check card fee income, offset by a $2.3 million net loss on sales of securities during the six months ended June 30, 2018 and a $547,000 decrease in service charges on deposit accounts.

Other expense of $97.2 million for the six months ended June 30, 2018 represented an increase of $6.7 million, or 7.4%, compared to $90.5 million for the six months ended June 30, 2017. The $6.7 million increase was primarily related to a $3.0 million increase in salaries expense, a $1.8 million increase in employee benefits expense, a $887,000 increase in furniture and equipment expense, a $358,000 increase in state tax expense, a $259,000 increase in non-loan related losses which are included in miscellaneous expense, and a $307,000 increase in occupancy expense, offset by a $418,000 decrease in other insurance.

Federal income tax expense of $11.8 million for the six months ended June 30, 2018 represented a decrease of $5.7 million compared to $17.6 million for the six months ended June 30, 2017.  The decrease in federal income tax expense was largely due to a decrease in the corporate federal income tax rate from 35% to 21%, effective January 1, 2018.

PNB's results for the first six months of 2018 and 2017, and for the fiscal year ended December 31, 2017, included income and

Credit Metrics and Provision for (Recovery of) Loan Losses

The provision for (recovery of) loan losses is the amount added to the allowance for loan and lease losses ("ALLL") to ensure the allowance is sufficient to absorb probable, incurred credit losses. The amount of the provision for (recovery of) loan losses is determined by management after reviewing the risk characteristics of the loan portfolio, historic and current loan loss experience and current economic conditions.

Park's Ohio-based subsidiaries, PNB and GFSC, are the only subsidiaries that carry an ALLL balance. The table below provides additional information on the provision for (recovery of) loan losses and the ALLL for Park, Park's Ohio-based operations, and SEPH for the three-month and six-month periods ended June 30, 2018 and 2017.

SEPH, as a non-bank subsidiary of Park, does not carry an ALLL balance, but recognizes a provision for loan losses when a charge-off is taken and recognizes a recovery of loan losses when a recovery is received.

The following table provides additional information related to the allowance for loan losses for Park's Ohio-based operations, including information related to specific reserves and general reserves, at June 30, 2018, December 31, 2017 and June 30, 2017.

The allowance for loan losses of $49.5 million at June 30, 2018 represented a $536,000, or 1.1%, decrease compared to $50.0 million at December 31, 2017. This decrease was the result of a $1.2 million decrease in general reserves, offset by a $712,000 increase in specific reserves. The decrease in general reserves was largely the result of a decline in loan balances.

Generally, management obtains updated valuations for all nonperforming loans, including those held at SEPH, at least annually. As new valuation information is received, management performs an evaluation and applies a discount for anticipated disposition costs to determine the net realizable value of the collateral, which is compared against the outstanding principal balance to determine if additional write-downs are necessary.

Nonperforming Assets: Nonperforming assets include: 1) loans whose interest is accounted for on a nonaccrual basis; 2) TDRs on accrual status; 3) loans which are contractually past due 90 days or more as to principal or interest payments but whose interest continues to accrue; (4) OREO which results from taking possession of property that served as collateral for a defaulted loan; and (5) other nonperforming assets which consist of receivables acquired through a loan workout.

The following table compares Park’s nonperforming assets at June 30, 2018, December 31, 2017 and June 30, 2017.

Impaired Loans:  Park’s allowance for loan losses includes an allocation for loans specifically identified as impaired under GAAP. At June 30, 2018, loans considered to be impaired consisted substantially of commercial loans graded as "substandard" or “doubtful” and placed on non-accrual status.  Specific reserves on impaired commercial loans are typically based on management’s best estimate of the fair value of collateral securing these loans. The amount ultimately charged off for these loans may be different from the specific reserve as the ultimate liquidation of the collateral may be for amounts different from management’s estimates.

When determining the quarterly loan loss provision, Park reviews the grades of commercial loans. These loans are graded from 1 to 8. 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. Commercial loans graded a 6 (substandard), also considered to be watch list credits, represent higher credit risk than those rated special mention and, as a result, a higher loan loss reserve percentage is allocated to these loans. Commercial loans that are graded a 7 (doubtful) are shown as nonperforming and Park charges these loans down to their fair value by taking a partial charge-off or recording a specific reserve. Certain 6-rated loans and all 7-rated loans are included within the impaired category. A loan is deemed impaired when management determines that 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.

As of June 30, 2018, Park had taken partial charge-offs of $11.4 million related to the $61.7 million of commercial loans considered to be impaired, compared to partial charge-offs of $10.0 million related to the $56.5 million of impaired commercial loans at December 31, 2017.

Allowance for loan losses: Loss factors are reviewed quarterly and updated at least annually to reflect recent loan loss history and incorporate current risks and trends which may not be recognized in historical data. The historical loss factors were last updated in the fourth quarter of 2017 to incorporate losses through December 31, 2017.

The allowance for loan losses related to performing commercial loans was $31.0 million or 1.18% of the outstanding principal balance of performing commercial loans at June 30, 2018. At June 30, 2018, the coverage level within the commercial loan portfolio was approximately 3.18 years compared to 3.24 years at December 31, 2017. Historical loss experience, defined as charge-offs plus changes in specific reserves, over the 96-month period ended December 31, 2017, for the commercial loan portfolio was 0.37%. This 96-month loss experience includes only the performance of the PNB loan portfolio and excludes the impact of PNB participations in Vision loans.

The overall reserve of 1.18% for other accruing commercial loans breaks down as follows: pass-rated commercial loans are reserved at 1.18%; special mention commercial loans are reserved at 2.83%; and substandard commercial loans are reserved at 9.65%. The reserve levels for pass-rated, special mention and substandard commercial loans in excess of the 96-month loss experience of 0.37% are due to the following factors which management reviews on a quarterly or annual basis:

• Historical Loss Factor: Management updated the historical loss calculation during the fourth quarter of 2017, incorporating net charge-offs plus changes in specific reserves through December 31, 2017. With the addition of 2017 historical losses, management extended the historical loss period to 96 months from 84 months. The 96-month historical loss period captures all annual periods subsequent to June 2009, the end of the most recent recession, thus encompassing the full economic cycle to date.

67

• Loss Emergence Period Factor:At least annually, management calculates the loss emergence period for each commercial loan segment. This loss emergence period is calculated based upon the average period of time it takes from the probable occurrence of a loss event to the credit being moved to nonaccrual. If the loss emergence period for any commercial loan segment is greater than one year, management applies additional general reserves to all performing loans within that segment of the commercial loan portfolio. The loss emergence period was last updated in the fourth quarter of 2017.

• Loss Migration Factor:Park’s commercial loans are individually risk graded. If loan downgrades occur, the probability of default increases, and accordingly, management allocates a higher percentage reserve to those accruing commercial loans graded special mention and substandard. Annually, management calculates a loss migration factor for each commercial loan segment for special mention and substandard credits based on a review of losses over the period of time a loan takes to migrate from pass-rated to impaired. The loss migration factor was last updated in the fourth quarter of 2017.

• Environmental Loss Factor:Management has identified certain macroeconomic factors that trend in accordance with losses in Park’s commercial loan portfolio. These macroeconomic factors are reviewed quarterly and the adjustments made to the environmental loss factor impacting each segment in the performing commercial loan portfolio correlate to changes in the macroeconomic environment. There was no change to the environmental loss factor during the second quarter of 2018.

Generally, consumer loans are not individually graded. Consumer loans include: (1) mortgage and installment loans included in the construction real estate segment of the loan portfolio; (2) mortgage, home equity lines of credit ("HELOC"), and installment loans included in the residential real estate segment of the loan portfolio; and (3) all loans included in the consumer segment of the loan portfolio. The amount of loan loss reserve assigned to these loans is based on historical loss experience over the past 96 months, through December 31, 2017. Management generally considers a one-year coverage period (the “Historical Loss Factor”) appropriate because the probable loss on any given loan in the consumer loan pool should ordinarily become apparent in that time frame. However, management may incorporate adjustments to the Historical Loss Factor as circumstances warrant additional reserves (e.g., increased loan delinquencies, improving or deteriorating economic conditions, changes in lending management and changes in underwriting standards). At June 30, 2018, the coverage level within the consumer loan portfolio was approximately 1.89 years compared to 1.92 years at December 31, 2017. Historical loss experience, over the 96-month period ended December 31, 2017, for the consumer loan portfolio was 0.34%.

The judgmental increases discussed above incorporate management’s evaluation of the impact of environmental qualitative factors which pose additional risks and assignment of a component of the allowance for loan losses in consideration of these factors. Such environmental qualitative factors include: global, national and local economic trends and conditions; experience, ability and depth of lending management and staff; effects of any changes in lending policies and procedures; and levels of, and trends in, consumer bankruptcies, delinquencies, impaired loans and charge-offs and recoveries. The determination of this component of the allowance for loan losses requires considerable management judgment. Actual loss experience may be more or less than the amount allocated.

Other Income

Other income increased by $2.5 million to $23.2 million for the quarter ended June 30, 2018, compared to $20.7 million for the second quarter of 2017, and increased by $10.5 million to $50.1 million for the six months ended June 30, 2018, compared to $39.7 million for the six months ended June 30, 2017.

Income from fiduciary activities, which represents revenue earned from Park’s trust activities, increased by $641,000, or 10.6%, to $6.7 million for the three months ended June 30, 2018, compared to $6.0 million for the same period in 2017 and increased $1.5 million, or 13.2%, to $13.1 million for the six months ended June 30, 2018, compared to $11.5 million for the same period in 2017. Fiduciary fees charged are generally based on the market value of customer accounts. The average market value for assets under management for the six months ended June 30, 2018 was $5,422 million compared to $4,926 million for the six months ended June 30, 2017.

Service charges on deposits decreased by $330,000, or 10.5%, to $2.8 million for the three months ended June 30, 2018, compared to $3.2 million for the same period in 2017 and decreased $547,000, or 8.7%, to $5.7 million for the six months ended June 30, 2018, compared to $6.3 million for the same period in 2017, largely as a result of a decline in non-sufficient funds (NSF) fee income.

Other service income increased by $1.4 million, or 22.3%, to $7.6 million for the six months ended June 30, 2018, compared to $6.3 million for the same period of 2017. The primary reason for the increase was the recovery of fees from certain SEPH impaired relationships.

Checkcard fee income increased by $342,000, or 8.5%, to $4.4 million for the three months ended June 30, 2018, compared to $4.0 million for the same period of 2017 and increased $583,000, or 7.5%, to $8.4 million for the six months ended June 30, 2018, compared to $7.8 million for the same period of 2017. The increases in 2018 were attributable to continued increases in the volume of debit card transactions.

Gain on sale of OREO, net increased by $4.0 million, to $4.2 million for the six months ended June 30, 2018, compared to $153,000 for the same period in 2017. The increase is primarily due to a $4.1 million gain on the sale of one OREO property during the first three months of 2018, which was partially participated to PNB from SEPH.

During the six months ended June 30, 2018, investment securities with a book value of $254.3 million were sold at a net loss of $2.3 million. There were no securities sold during the same period of 2017.

During the six months ended June 30, 2018, there were unrealized gains on equity securities of $3.8 million. Prior to January 1, 2018, unrealized gains on equity securities were recognized in other comprehensive income. With the adoption of ASU 2016-01 on January 1, 2018, Park recorded an increase of $1.9 million to beginning retained earnings with all future changes in unrealized gains/loss on equity securities being recorded on the consolidated condensed statement of income.

Miscellaneous income increased by $1.5 million to $2.6 million for the three months ended June 30, 2018, compared to $1.1 million for the three months ended June 30, 2017 and increased $1.7 million to $3.4 million for the six months ended June 30, 2018, compared to $1.7 million for the six months ended June 30, 2017. The increase for the year-to-date periods was primarily related to a $752,000 increase in income from equity investments, a $486,000 increase in net gain on sale of assets, and a $308,000 increase in income from the operation of OREO properties for the six months ended June 30, 2018, compared to the six months ended June 30, 2017.

Other Expense

Other expense increased by $3.0 million to $52.5 million for the quarter ended June 30, 2018, compared to $49.6 million for the second quarter of 2017, and increased by $8.4 million to $106.8 million for the six months ended June 30, 2018, compared to $98.5 million for the six months ended June 30, 2017.

Salaries increased by $1.1 million, or 4.8%, to $24.1 million for the three months ended June 30, 2018, compared to $23.0 million for the same period in 2017 and increased by $3.7 million, or 8.1%, to $49.4 million for the six months ended June 30, 2018, compared to $45.7 million for the same period in 2017. The increase for the six months ended June 30, 2018 was due to a $1.1 million one-time incentive paid out in March 2018, along with an $1.2 million increase in salary expense, a $629,000 increase in share-based compensation expense related to PBRSU awards granted under the 2013 Incentive Plan (prior to 2017) and the 2017 Employee LTIP, and a $500,000 increase in incentive compensation expense.

Employee benefits increased by $1.4 million, or 22.9%, to $7.6 million for the three months ended June 30, 2018, compared to $6.2 million for the same period in 2017 and increased $2.0 million, or 15.7%, to $14.7 million for the six months ended June 30, 2018, compared to $12.7 million for the same period in 2017. The increase for the six months ended June 30, 2018 was primarily due to a $788,000 increase in expense related to Park's voluntary salary deferral plan, a $611,000 increase in group insurance costs and a $555,000 increase in pension service cost expense. The Company contribution match under the voluntary salary deferral plan was increased from 25% to 50% in March of 2018.

Furniture and equipment expense increased by $373,000, or 10.2%, to $4.0 million for the three months ended June 30, 2018, compared to $3.6 million for the same period in 2017 and increased $904,000, or 12.5%, to $8.2 million for the six months ended June 30, 2018, compared to $7.3 million for the same period in 2017. The increases for the three and six months ended June 30, 2018 were primarily due to maintenance and repairs on equipment.

Professional fees and services increased by $105,000, or 1.7%, to $6.1 million for the three months ended June 30, 2018, compared to $6.0 million for the same period in 2017 and increased $1.5 million, or 13.5%, to $12.3 million for the six months ended June 30, 2018, compared to $10.8 million for the same period in 2017. The $786,000 increase at SEPH for the six months ended June 30, 2018 was primarily the result of a $1.2 million increase in management and consulting fees resulting from the collection of payments on certain SEPH impaired loan relationships during the first six months of 2018, offset by a $435,000 decrease in legal expense. The $680,000 increase at the Ohio based operations for the six months ended June 30, 2018 was largely the result of a $504,000 increase in legal expense at the Parent Company primarily related to the acquisition of NewDominion Bank, which was effective July 1, 2018.

Income Tax

Federal income tax expense was $5.8 million for the second quarter of 2018, compared to $7.3 million for the second quarter of 2017, and was $11.9 million for the six months ended June 30, 2018, compared to $15.2 million for the six months ended June 30, 2017. Effective January 1, 2018, the federal corporate income tax rate was lowered to 21% from 35%. The effective federal income tax rate for the second quarter of 2018 was 17.1%, compared to 27.8% for the same period in 2017 and the effective federal income tax rate for the six months ended June 30, 2018 was 16.7%, compared to 27.8% for the six months ended June

71

30, 2017. The difference between the statutory federal income tax rate and Park’s effective federal income tax rate is due to permanent tax differences, primarily consisting of tax-exempt interest income from investments and loans, the tax benefit of investments in qualified affordable housing projects, bank owned life insurance income, and dividends paid on the common shares held within Park’s salary deferral plan. Park expects permanent tax differences for the 2018 year will be approximately $5.4 million.

Park and its Ohio-based affiliates do not pay state income taxes to the state of Ohio, but Park pays a franchise tax based on Park's year-end equity. The franchise tax expense is included in “state taxes” as part of other expense on Park’s Consolidated Condensed Statements of Income.

Comparison of Financial Condition

At June 30, 2018 and December 31, 2017

Changes in Financial Condition

Total assets decreased by $75.5 million, or 1.0%, during the first six months of 2018 to $7,462 million at June 30, 2018, compared to $7,538 million at December 31, 2017. This decrease was primarily due to the following:

• Loans decreased by $47.5 million, or 0.9%, to $5,325 million at June 30, 2018, compared to $5,372 million at December 31, 2017.

• Cash and cash equivalents decreased by $23.0 million to $146.2 million at June 30, 2018, compared to $169.1 million at December 31, 2017. Money market instruments were $23.2 million at June 30, 2018, compared to $37.2 million at December 31, 2017 and Cash and due from banks were $122.9 million at June 30, 2018, compared to $131.9 million at December 31, 2017.

Total liabilities decreased by $74.5 million, or 1.1%, during the first six months of 2018 to $6,707 million at June 30, 2018, from $6,782 million at December 31, 2017. This decrease was primarily due to the following:

• Short-term borrowings decreased by $175.2 million, or 44.8%, to $216.1 million at June 30, 2018, compared to $391.3 million at December 31, 2017.

• Long-term borrowings decreased by $100.0 million, or 20.0%, to $400.0 million at June 30, 2018, compared to $500.0 million at December 31, 2017.

• Total deposits increased by $198.5 million, or 3.4%, to $6,016 million at June 30, 2018, compared to $5,817 million at December 31, 2017.

Total shareholders’ equity decreased by $1.0 million, or 0.1%, to $755.1 million at June 30, 2018, from $756.1 million at December 31, 2017.

• Retained earnings increased by $31.6 million during the period as a result of net income of $59.4 million and cumulative effects of changes in accounting principle of $5.7 million, offset by common share dividends of $33.2 million.

• Treasury shares increased by $4.5 million during the period as a result of the repurchase of treasury shares, offset by the issuance of treasury shares.

• Accumulated other comprehensive loss, net of taxes increased by $28.6 million during the period as a result of unrealized net holding losses on securities available for sale, net of taxes, of $25.8 million, and the cumulative effects of changes in accounting principle of $4.8 million, offset by a net realized loss on the sale of securities of $2.0 million reclassified from accumulated other comprehensive loss.

Increases or decreases in the investment securities portfolio, short-term borrowings and long-term debt are greatly dependent upon the growth in loans and deposits. The primary objective of management is to grow loan and deposit totals. To the extent that management is unable to grow loan totals at a desired growth rate, additional investment securities may be acquired. Likewise, both short-term borrowings and long-term debt are utilized to fund the growth in earning assets if the growth in deposits and cash flow from operations are not sufficient to do so.

Liquidity

Cash provided by operating activities was $60.5 million and $40.0 million for the six months ended June 30, 2018 and 2017, respectively. Net income was the primary source of cash from operating activities for each of the six months ended June 30, 2018 and 2017.

Cash provided by investing activities was $32.4 million for the six months ended June 30, 2018 and cash used in investing activities was $89.5 million for the six months ended June 30, 2017. Proceeds from the sale, repayment, or maturity of investment securities provide cash and purchases of investment securities use cash. Net investment securities transactions used cash of $29.6 million for the six months ended June 30, 2018 and provided cash of $5.5 million for the six months ended June 30, 2017. Another major use or source of cash in investing activities is the net increase or decrease in the loan portfolio. Cash provided by the net decrease in the loan portfolio was $53.2 million and cash used by the net increase in the loan portfolio was $94.2 million for the six months ended June 30, 2018 and 2017, respectively.

73

Cash used in financing activities was $115.9 million for the six months ended June 30, 2018 and cash provided by financing activities was $314.1 million for the six months ended June 30, 2017. A major source of cash for financing activities is the net change in deposits. Deposits increased and provided $198.5 million and $439.6 million of cash for the six months ended June 30, 2018 and 2017, respectively. Another major source/use of cash from financing activities is borrowings in the form of short-term borrowings and long-term debt. For the six months ended June 30, 2018, net short-term borrowings decreased and used $175.2 million in cash, and net long-term borrowings decreased and used $100.0 million in cash. For the six months ended June 30, 2017, net short-term borrowings decreased and used $211.0 million in cash, while net long-term borrowings increased and provided $120.0 million in cash. Finally, cash declined by $32.9 million for the six months ended June 30, 2018 and $28.8 million for the six months ended June 30, 2017, from the payment of dividends.

Effective liquidity management ensures that the cash flow requirements of depositors and borrowers, as well as the operating cash needs of the Corporation, are met. Funds are available from a number of sources, including the securities portfolio, the core deposit base, FHLB borrowings, the capability to securitize or package loans for sale, and a $50.0 million revolving line of credit with another financial institution, which had an outstanding balance of $10.0 million as of June 30, 2018. The Corporation’s loan to asset ratio was 71.36% at June 30, 2018, compared to 71.28% at December 31, 2017 and 68.51% at June 30, 2017. Cash and cash equivalents were $146.2 million at June 30, 2018, compared to $169.1 million at December 31, 2017 and $411.1 million at June 30, 2017. Management believes that the present funding sources provide more than adequate liquidity for the Corporation to meet its cash flow needs.

Capital Resources

Shareholders’ equity at June 30, 2018 was $755.1 million, or 10.1% of total assets, compared to $756.1 million, or 10.0% of total assets, at December 31, 2017 and $752.2 million, or 9.6% of total assets, at June 30, 2017.

Financial 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 AFS debt securities in computing regulatory capital. During the first quarter of 2015, Park adopted the Basel III regulatory capital framework as approved by the federal banking agencies. The adoption of this framework modified the calculation of the various capital ratios, added a new ratio, common equity tier 1, and revised the adequately and well capitalized thresholds under the prompt corrective action regulations applicable to PNB. Additionally, under this framework, in order to avoid limitations on capital distributions, including dividend payments, and repurchases of common shares, Park must hold a capital conservation buffer above the adequately capitalized risk-based capital ratios. The capital conservation buffer is being phased in from 0.0% for 2015 to 2.50% by 2019. The capital conservation buffer for 2018 is 1.875%. The amounts shown below as the adequately capitalized ratio plus capital conservation buffer includes the fully phased-in 2.50% buffer. The Federal Reserve Board has also adopted requirements Park must satisfy to be deemed "well-capitalized" and to remain a financial holding company.

Park and PNB met each of the well capitalized ratio guidelines applicable to them at June 30, 2018. The following table indicates the capital ratios for PNB and Park at June 30, 2018 and December 31, 2017.

	As of June 30, 2018
	Leverage		Tier 1 Risk-Based		Common Equity Tier 1		Total Risk-Based
The Park National Bank	7.93	%	10.85	%	10.85	%	12.18	%
Park National Corporation	10.12	%	13.75	%	13.48	%	14.66	%
Adequately capitalized ratio	4.00	%	6.00	%	4.50	%	8.00	%
Adequately capitalized ratio plus capital conservation buffer	4.00	%	8.50	%	7.00	%	10.50	%

Well capitalized ratio (Park)	N/A		6.00	%	N/A		10.00	%

Contractual Obligations and Commitments

In the ordinary course of operations, Park enters into certain contractual obligations. Such obligations include the funding of operations through debt issuances as well as leases for premises. See page 43 of Park’s 2017 Annual Report (Table 38) for disclosure concerning contractual obligations and commitments at December 31, 2017. There were no significant changes in contractual obligations and commitments during the first six months of 2018.

Financial Instruments with Off-Balance Sheet Risk

PNB is a 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 instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated financial statements.

The exposure to credit loss (for PNB) 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 instruments. PNB 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:

(In thousands)	June 30, 2018		December 31, 2017
Loan commitments	$	935,018	$	893,205
Standby letters of credit	$	12,068	$	13,421

ITEM 3 – QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Management reviews interest rate sensitivity on a monthly basis by modeling the consolidated financial statements under various interest rate scenarios. The primary reason for these efforts is to guard Park from adverse impacts of unforeseen changes in interest rates. Management continues to believe that further changes in interest rates will have a small impact on net income, consistent with the disclosure on page 43 of Park’s 2017 Annual Report.

On page 43 (Table 37) of Park’s 2017 Annual Report, management reported that Park’s twelve-month cumulative rate sensitivity gap was a positive (assets exceeding liabilities) $407 million or 5.88% of total interest earning assets at December 31, 2017. At June 30, 2018, Park’s twelve-month cumulative rate sensitivity gap was a positive (assets exceeding liabilities) $204 million or 2.95% of total interest earning assets.

Management supplements the interest rate sensitivity gap analysis with periodic simulations of balance sheet sensitivity under various interest rate and what-if scenarios to better forecast and manage the net interest margin. Management uses a 50 basis point change in market interest rates per quarter for a total of 200 basis points per year in evaluating the impact of changing interest rates on net interest income and net income over a twelve-month horizon.

On page 43 of Park’s 2017 Annual Report, management reported that at December 31, 2017, the earnings simulation model projected that net income would decrease by 1.8% using a rising interest rate scenario and decrease by 5.2% using a declining interest rate scenario over the next year. At June 30, 2018, the earnings simulation model projected that net income would decrease by 1.7% using a rising interest rate scenario and would decrease by 1.8% in a declining interest rate scenario. At June 30, 2018, management continues to believe that gradual changes in interest rates (50 basis points per quarter for a total of 200 basis points per year) will have a small impact on net income.

ITEM 4 – CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

With the participation of the Chief Executive Officer and President (the principal executive officer) and the Chief Financial Officer, Secretary and Treasurer (the principal financial officer) of Park, Park’s management has evaluated the effectiveness of Park’s disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the quarterly period covered by this Quarterly Report on Form 10-Q. Based on that evaluation, Park’s Chief Executive Officer and President and Park’s Chief Financial Officer, Secretary and Treasurer have concluded that:

• information required to be disclosed by Park in this Quarterly Report on Form 10-Q and other reports that Park files or submits under the Exchange Act would be accumulated and communicated to Park’s management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure;

• information required to be disclosed by Park in this Quarterly Report on Form 10-Q and the other reports that Park files or submits under the Exchange Act would be recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms; and

• Park’s disclosure controls and procedures were effective as of the end of the quarterly period covered by this Quarterly Report on Form 10-Q.

Changes in Internal Control Over Financial Reporting

There were no changes in Park’s internal control over financial reporting (as defined in Rule 13a-5(f) under the Exchange Act) that occurred during Park’s fiscal quarter ended June 30, 2018, that have materially affected, or are reasonably likely to materially affect, Park’s internal control over financial reporting.

76

PART II – OTHER INFORMATION

Item 1.       Legal Proceedings

There are no pending legal proceedings to which Park or any of its subsidiaries is a party or to which any of their property is subject, except for routine legal proceedings to which Park's subsidiaries are parties to incidental to their respective businesses. Park considers none of those proceedings to be material.

Item 1A.     Risk Factors

There are certain risks and uncertainties in our business that could cause our actual results to differ materially from those anticipated. In “ITEM 1A. RISK FACTORS” of Part I of Park’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017 (the “2017 Form 10-K”), we included a detailed discussion of our risk factors. All of these risk factors should be read carefully in connection with evaluating our business and in connection with the forward-looking statements contained in this Quarterly Report on Form 10-Q. Any of the risks described in the 2017 Form 10-K could materially adversely affect our business, financial condition or future results and the actual outcome of matters as to which forward-looking statements are made. These are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

Total	50,000	$	115.66	50,000	1,330,000

(1) The number shown represents, as of the end of each period, the maximum number of common shares that may yet be purchased as part of Park’s publicly announced stock repurchase authorization to fund the 2017 Employees LTIP which became effective on April 24, 2017, the 2017 Non-Employee Directors LTIP which became effective on April 24, 2017 and Park's publicly announced 2017 stock repurchase authorization which became effective on January 23, 2017.

At the 2017 Annual Meeting of Shareholders held on April 24, 2017, Park's shareholders approved the 2017 Employees LTIP and the 2017 Non-Employee Directors LTIP. The common shares to be issued and delivered under the 2017 Employees LTIP and the 2017 Non-Employee Directors LTIP may consist of either common shares currently held or common shares subsequently acquired by Park as treasury shares. No newly-issued common shares will be delivered under the 2017 Employees LTIP or the 2017 Non-Employee Directors LTIP. On April 24, 2017, Park's Board of Directors authorized the purchase, from time to time, of up to 750,000 Park common shares and 150,000 common shares, respectively, to be held as

77

treasury shares for subsequent issuance and delivery under the 2017 Employees LTIP and the 2017 Non-Employee Directors LTIP.

On January 23, 2017, the Park Board of Directors authorized Park to purchase, from time to time, up to an aggregate of 500,000 Common Shares. Purchases may be made through NYSE American, in the over-the-counter market or in privately negotiated transactions, in each case in compliance with applicable laws and regulations and the rules applicable to issuers having securities listed on NYSE American. Purchases will be made upon such terms and conditions and at such times and in such amounts as any one or more of the authorized officers of Park deem to be appropriate, subject to market conditions, regulatory requirements and other factors, and in the best interest of Park and Park's shareholders. The January 23, 2017 stock repurchase authorization is distinct from the stock repurchase authorization to fund the 2017 Employees LTIP and the 2017 Non-Employee Directors LTIP.

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, 2018 are not necessarily indicative of the operating results to be anticipated for the fiscal year ending December 31, 2018.

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, 2017 from Park’s 2017 Annual Report to Shareholders (“Park's 2017 Annual Report”). Prior period financial statement reflect the retrospective application of Accounting Standards Update ("ASU") 2017-07 - Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This change in classification had no effect on reported net income.

Park’s significant accounting policies are described in Note 1 of the Notes to Consolidated Financial Statements included in Park’s 2017 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

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 issued but not yet effective accounting standards:

Adoption of New Accounting Pronouncements

ASU 2014-09 - Revenue from Contracts with Customers (Topic 606): In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). This 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. The majority of the Company's revenues come from interest income and other sources, including loans, leases, securities and derivatives, that are outside the scope of ASC 606. Certain services that fall within the scope of ASC 606 are presented within Other Income and are recognized as revenue as the Company satisfies its obligation to the customer. Services within the scope of ASC 606 include income from fiduciary activities, service charges on deposit accounts, other service income, checkcard fee income, ATM fees, and gain on sale of OREO, net. The adoption of this guidance on January 1, 2018 did not have a material impact on Park's consolidated financial statements. However, the adoption of this standard resulted in additional disclosures beginning with the first quarter 2018 Form 10-Q. Reference Note 19, Revenue from Contracts with Customers, for further discussion on the Company's accounting policies for revenue sources within the scope of ASC 606.

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 reflected in 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, this ASU clarifies guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale ("AFS") 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 on January 1, 2018 resulted in an $1.9 million increase to beginning retained earnings and a $995,000 increase to beginning accumulated other comprehensive loss. Additional income of $3.2 million and $1.3 million was recorded in the first and second quarters of 2018, respectively, as a result of changes to the accounting for equity investments. Further, beginning with the first quarter of 2018, Park's fair value disclosures in Note 14, Fair Value, have incorporated the revised disclosure requirements for financial investments.

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 then current GAAP was either unclear or did 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.  The adoption of this guidance on January 1, 2018 did not have an impact on Park's consolidated financial statements. As such transactions arise, management will utilize the updated guidance in providing disclosures within Park’s consolidated condensed statements of cash flows. 

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. As a result of the adoption of this guidance on January 1, 2018, all prior periods have been recast to separately record the service cost component and other components of net benefit cost. For all periods presented, this resulted in an increase in other income and an offsetting increase in other expense with no change to net income. See Note 12, Benefit Plans, for further details.

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 concerning which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting under Topic 718. 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 on January 1, 2018 did not impact Park's consolidated financial statements.

ASU 2017-12 - Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities: In August 2017, the FASB issued ASU 2017-12 - Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. This ASU amends the current guidance with the objective of improving the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities in its financial statements. In addition, this ASU amends the current guidance to simplify the application of the hedge accounting guidance. 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 early adoption of this guidance on July 1, 2018 did not have an impact on Park's consolidated financial statements. Park will apply this guidance to future transactions.

ASU 2018-02 - Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income: In February 2018, the FASB issued ASU 2018-02 -Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This ASU allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects, resulting from the newly - enacted federal corporate income tax rate. The amount of the reclassification is the difference between the historical federal corporate income tax rate and the newly-enacted 21% federal corporate income tax rate. The 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 early adoption of this guidance effective January 1, 2018 resulted in a $3.8 million increase to Park's accumulated other comprehensive loss and a $3.8 million increase to retained earnings.

ASU 2018-03 - Technical Corrections and Improvements to Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. In February 2018, the FASB issued ASU 2018-03 - Technical Corrections and Improvements to Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. This ASU includes amendments that clarify certain aspects of the guidance issued in ASU 2016-01. Park considered this clarification in determining the appropriate adoption of ASU 2016-01 effective as of January 1, 2018.

Issued But Not Yet Effective Accounting Standards

ASU 2016-02 - Leases (Topic 842): In February 2016, the FASB issued ASU 2016-02 - Leases (Topic 842). This 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 2016-13 - 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 ("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 model requires an entity to estimate 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 the CECL model and is currently in the process of implementing a software solution to assist in implementing the adoption of this ASU. Management plans to run our current allowance model and a CECL model concurrently for 12 months prior to the adoption of this guidance on January 1, 2020.

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.

The following table summarizes the impact of retrospective application of this ASU to the consolidated condensed statement of income for the three and six months ended June 30, 2017.

Management’s general practice is to proactively charge down loans individually evaluated for impairment to the fair value of the underlying collateral. At June 30, 2018 and December 31, 2017, there were $9.2 million and $7.9 million, respectively, of partial charge-offs on loans individually evaluated for impairment with no related allowance recorded. At June 30, 2018 and December 31, 2017, there were $2.2 million and $2.1 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, 2018 and December 31, 2017 of $1.4 million and $0.7 million, respectively. These loans with specific reserves had a recorded investment of $5.3 million and $3.5 million as of June 30, 2018 and December 31, 2017, 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. The following table presents the average recorded investment and interest income recognized subsequent to impairment on loans individually evaluated for impairment as of and for the three and six months ended June 30, 2018 and June 30, 2017:

Credit Quality Indicators

Management utilizes past due information as a credit quality indicator across the loan portfolio. Past due information as of June 30, 2018 and December 31, 2017 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 a 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.

The tables below present the recorded investment by loan grade at June 30, 2018 and December 31, 2017 for all commercial loans:

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 three-month periods ended June 30, 2018 and June 30, 2017 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. The TDR classification was removed on $1.9 million of loans during the three-month period ended June 30, 2018 and $2.2 million of loans during the six-month period ended June 30, 2018. There were no TDR classifications removed during the three-month or six-month periods ended June 30, 2017.

At June 30, 2018 and December 31, 2017, there were $23.9 million and $38.5 million, respectively, of TDRs included in the nonaccrual loan totals. At June 30, 2018 and December 31, 2017, $18.1 million and $32.4 million, respectively, of these nonaccrual TDRs were performing in accordance with the terms of the restructured note. As of June 30, 2018 and December 31, 2017, loans with a recorded investment of $16.4 million and $20.2 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 June 30, 2018 and December 31, 2017, Park had commitments to lend $0.6 million and $1.3 million, respectively, of additional funds to borrowers whose outstanding loan terms had been modified in a TDR.

At both June 30, 2018 and December 31, 2017, there were $0.5 million of specific reserves related to TDRs. Modifications made in 2017 and 2018 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. There were no additional specific reserves recorded during the three-month period ended June 30, 2018 as a result of TDRs identified in the period. Additional specific reserves of $10,000 were recorded during the three-month period ended June 30, 2017 as a result of TDRs identified in the period. Additional specific reserves of $10,000 and $290,000 were recorded during the six-month periods ended June 30, 2018 and June 30, 2017, respectively, as a result of TDRs identified in the respective periods.

The terms of certain other loans were modified during the three-month and six-month periods ended June 30, 2018 and June 30, 2017 that did not meet the definition of a TDR. Substandard commercial loans modified during the three-month and six-month periods ended June 30, 2018 which did not meet the definition of a TDR had a total recorded investment of $0.1 million and $0.2 million, respectively. There were no substandard commercial loans modified during the three-month period ended June 30, 2017 which did not meet the definition of a TDR. Substandard commercial loans with a recorded investment of $0.1 million were modified during the six-month period ended June 30, 2017 which did not meet the definition of a TDR. 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. Consumer loans modified during the three-month and six-month periods ended June 30, 2018 which did not meet the definition of a TDR had a total recorded investment of $4.7 million and $11.0 million, respectively. Consumer loans with a recorded investment of $3.4 million and $5.0 million were modified during the three-month and six-month periods ended June 30, 2017 and did not meet the definition of a TDR. 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 periods ended June 30, 2018 and June 30, 2017, as well as the recorded investment of these contracts at June 30, 2018 and June 30, 2017. The 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

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 2017 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 following are factors management reviews on a quarterly or annual basis.

• Historical Loss Factor: Management updated the historical loss calculation during the fourth quarter of 2017, incorporating net charge-offs plus changes in specific reserves through December 31, 2017.  With the addition of 2017 historical losses, management extended the historical loss period to 96 months from 84 months. The 96-month historical loss period captures all annual periods subsequent to June 2009, the end of the most recent recession, thus encompassing the full economic cycle to date.

• Loss Emergence Period Factor: At least annually, management calculates the loss emergence period for each commercial loan segment. This loss emergence period is calculated based upon the average period of time it takes from the probable occurrence of a loss event to the credit being moved to nonaccrual. If the loss emergence period for any commercial loan segment is greater than one year, management applies additional general reserves to all performing loans within that segment of the commercial loan portfolio. The loss emergence period was last updated in the fourth quarter of 2017.

• Loss Migration Factor: Park’s commercial loans are individually risk graded. If loan downgrades occur, the probability of default increases, and accordingly, management allocates a higher percentage reserve to those accruing commercial loans graded special mention and substandard. Annually, management calculates a loss migration factor for each commercial loan segment for special mention and substandard credits based on a review of losses over the period of time a loan takes to migrate from pass-rated to impaired. The loss migration factor was last updated in the fourth quarter of 2017.

• Environmental Loss Factor:Management has identified certain macroeconomic factors that trend in accordance with losses in Park’s commercial loan portfolio. These macroeconomic factors are reviewed quarterly and the adjustments made to the environmental loss factor impacting each segment in the performing commercial loan portfolio correlate to changes in the macroeconomic environment. There was no change to the environmental loss factor during the second quarter of 2018.

The activity in the allowance for loan losses for the three-month and six-month periods ended June 30, 2018 and June 30, 2017 is summarized in the following tables.

Loans collectively evaluated for impairment in the following tables include all performing loans at June 30, 2018 and December 31, 2017, as well as nonperforming loans internally classified as consumer loans. Nonperforming consumer loans are not typically individually evaluated for impairment, but receive a portion of the statistical allocation of the allowance for loan losses. Loans individually evaluated for impairment include all impaired loans internally classified as commercial loans at June 30, 2018 and December 31, 2017, which are evaluated for impairment in accordance with U.S. GAAP (see Note 1 of the Notes to Consolidated Financial Statements included in Park’s 2017 Annual Report).

Management does not believe any of the unrealized/unrecognized losses at June 30, 2018 or December 31, 2017 represented other-than-temporary impairment. 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, 2018, 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 remaining average life of the entire investment portfolio is estimated to be 4.9 years.

There were no sales of investment securities during the three-month period ended June 30, 2018. During the six-month period ended June 30, 2018, Park sold certain AFS debt securities with a book value of $247.0 million at a loss of $2.6 million. Additionally, during the six-month period ended June 30, 2018, Park sold certain HTM debt securities with a book value of $7.4 million at a gain of $291,000. These HTM securities had been paid down by 96.3% of the principal outstanding at acquisition. There were no sales of investment securities during the three-month or six-month periods ended June 30, 2017.

Investment securities having an amortized cost of $618 million and $557 million at June 30, 2018 and December 31, 2017, 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 Federal Home Loan Bank ("FHLB") advance borrowings.

Other Investment Securities

Other Investment Securities

Other investment securities consist of stock investments in the FHLB, the Federal Reserve Bank ("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. Beginning on January 1, 2018, with the adoption of ASU 2016-01, changes in fair value are included in other income on the consolidated condensed statement of income as opposed to in accumulated other comprehensive loss on the consolidated condensed balance sheet. 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").

The carrying amount of other investment securities at June 30, 2018 and December 31, 2017 was as follows:

(In thousands)	June 30, 2018		December 31, 2017
FHLB stock	$	50,086	$	50,086

Equity investments carried at cost/modified cost (1)	2,589		3,500
Total other investment securities	$	70,129	$	63,746

⁽¹⁾There have been no impairments, downward adjustments, or upward adjustments made to equity investments carried at modified cost.

During the three months ended March 31, 2018, an equity investment previously carried at cost, with a carrying amount of $3.5 million, was measured at fair value as a readily determinable market value became available.

During the three and six months ended June 30, 2018, $0.3 million and $3.8 million, respectively, of unrealized gains were recorded within "unrealized gain on equity securities" on the consolidated condensed statements of income, which relate to investment securities held at June 30, 2018.

Park has a noncontributory defined benefit pension plan covering substantially all of its employees. The plan provides benefits based on an employee’s years of service and compensation.

There were no pension plan contributions for the three-month and six-month periods ended June 30, 2018 and 2017.

The following table shows the components of net periodic pension benefit income:

Park has entered into Supplemental Executive Retirement Plan Agreements (the “SERP Agreements”) with certain key officers of the Corporation and its subsidiaries which provide defined pension benefits in excess of limits imposed by federal tax law. The expense for the Corporation related to the SERP Agreements for the three months and six months ended June 30, 2018 and 2017 was as follows:

	Three Months Ended June 30,				Six Months Ended June 30,				Affected Line Item in the Consolidated Condensed Statement of Income

Interest cost	44		161		161		322		Miscellaneous expense
Total SERP expense	$	288	$	346	$	639	$	692

Previously, the net periodic benefit income/expense related to Park’s Pension and the expense related to the SERP Agreements had been recorded within the "Employee benefits" line item.

During the first quarter of 2018, Park adopted ASU 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement. 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. This ASU is required to be applied retrospectively to all periods presented. For all periods presented, this resulted in an increase in other income and an offsetting increase in other expense with no change to net income. As a practical expedient, Park used the amounts disclosed in "Note 12 - Pension Plan" of the Notes to Unaudited Consolidated Condensed Financial Statements, included under Item 1 of Part I of Park's Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2017 as the estimation basis for applying the retrospective presentation requirements.

The following table summarizes the impact of retrospective application of this ASU to the consolidated condensed statement of income for the three and six months ended June 30, 2017.

Loan Servicing

Loan Servicing

Park serviced sold mortgage loans of $1.38 billion at June 30, 2018, $1.37 billion at December 31, 2017 and $1.35 billion at June 30, 2017. At June 30, 2018, $2.6 million of the sold mortgage loans were sold with recourse, compared to $3.0 million at December 31, 2017 and $3.4 million at June 30, 2017. Management closely monitors the delinquency rates on the mortgage loans sold with recourse. At June 30, 2018 and December 31, 2017, management had established reserves of $43,000 and $270,000, respectively, to account for expected losses on loan repurchases.

When Park sells mortgage loans with servicing rights retained, these 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 with respect to 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. The amortization of MSRs is included within other service income in the consolidated condensed statements of income.

Activity for MSRs and the related valuation allowance follows:

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 (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 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.

There were no transfers between Level 1 and Level 2 during either of the three months ended June 30, 2018 or 2017. 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 (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.

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 table below presents a reconciliation of the beginning and ending balances of the Level 3 inputs for the three and six months ended June 30, 2018 and 2017, for financial instruments measured on a recurring basis and classified as Level 3:

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.

Assets Measured at Net Asset Value:

The adoption of ASU 2016-01 on January 1, 2018 required Park to evaluate the accounting for equity investments, including those previously held at cost. Under the new guidance, Park determined that its portfolio of equity investments in limited partnerships which provide mezzanine funding ("Partnership Investments") should be valued using the net asset value ("NAV") practical expedient in accordance with ASC 820. The adoption of this guidance on January 1, 2018, resulted in a $1.2 million increase to Partnership Investments, which are included within other assets on the consolidated condensed balance sheet, and a $922,000 increase to beginning retained earnings.

As of June 30, 2018 and December 31, 2017, Park had Partnerships Investments with a NAV of $9.4 million and $8.8 million, respectively. As of June 30, 2018 and December 31, 2017, Park had $7.1 million and $7.2 million in unfunded commitments related to these Partnership Investments. For the six months ended June 30, 2018, Park had recognized $752,000 in income related to these Partnership Investments.

The fair value of certain financial instruments at June 30, 2018 and December 31, 2017, was as follows:

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.

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 consisted of customer accounts and securities which are pledged on an individual security basis.

At June 30, 2018 and December 31, 2017, Park's repurchase agreement borrowings totaled $165 million and $183 million, respectively. These borrowings were collateralized with U.S. government and agency securities with a carrying value of $198 million and $213 million at June 30, 2018 and December 31, 2017, respectively. Declines in the value of the collateral would require Park to pledge additional securities. As of June 30, 2018 and December 31, 2017, Park had $961 million and $975 million, respectively, of available unpledged securities.

Revenue from Contracts with Customers

The Company adopted ASC 606 using the modified retrospective method applied to all contracts not completed as of January 1, 2018.  Results for reporting periods beginning on and after January 1, 2018 are presented under ASC 606 while prior period amounts continue to be reported in accordance with legacy GAAP.  The adoption of ASC 606 did not result in a change to the accounting for any of the in-scope revenue streams; as such, no cumulative effect adjustment was recorded. 

All of Park's revenue from contracts with customers within the scope of ASC 606 is recognized within "Other income" in the Consolidated Condensed Statements of Income.

⁽¹⁾ Of the $6.3 million of revenue included within "Other service income", approximately $4.4 million is within the scope of ASC 606, with the remaining $1.9 million consisting primarily of residential real estate loan fees which are out of scope.

⁽²⁾ Not within the scope of ASC 606.

⁽³⁾ "Miscellaneous" income includes brokerage income, safe deposit box rentals, and miscellaneous bank fees totaling $1.7 million, all of which are within the scope of ASC 606.

⁽⁴⁾ The Corporation elected the modified retrospective approach of adoption; therefore, prior period balances are presented under legacy GAAP and may not be comparable to current year presentation.

A description of Park's 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 its 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, 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. These fees are generally recognized at a point in time following the completion of a loan sale or related service activity.

Checkcard 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 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 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

On July 1, 2018, NewDominion Bank, a North Carolina state-chartered bank (“NewDominion”), merged with and into PNB, with PNB continuing as the surviving entity pursuant to the Agreement and Plan of Merger and Reorganization, dated as of January 22, 2018, by and among Park, PNB, and NewDominion. As of June 30, 2018, NewDominion had approximately $329 million in total assets, $278 million in total loans, and $284 million in total deposits. The acquisition was valued at approximately $79 million and resulted in Park issuing approximately 435,457 Park common shares and paying approximately $31 million in cash in exchange for the NewDominion common stock as merger consideration.

The assets and liabilities of NewDominion will be recorded on Park’s consolidated balance sheet at their preliminary estimated fair values as of July 1, 2018, the acquisition date, and NewDominion’s results of operations will be included in Park’s consolidated statement of income from that date. The initial accounting and determination of the fair values of the assets acquired and liabilities assumed in the acquisition was incomplete at the time of the filing of Park’s Quarterly Report on From 10-Q for the quarterly period ended June 30, 2018 (the “June 30, 2018 Form 10-Q”) due to the timing of the closing of the acquisition in relation to the deadline for the filing of Park’s June 30, 2018 Form 10-Q. A more complete disclosure of the business combination is expected to be reported in Park’s Quarterly Report on Form 10-Q for the quarterly period ending September 30, 2018.

For the six months ended June 30, 2018, Park recorded merger-related expenses of $0.5 million associated with the NewDominion acquisition.

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 issued but not yet effective accounting standards:

Adoption of New Accounting Pronouncements

ASU 2014-09 - Revenue from Contracts with Customers (Topic 606): In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). This 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. The majority of the Company's revenues come from interest income and other sources, including loans, leases, securities and derivatives, that are outside the scope of ASC 606. Certain services that fall within the scope of ASC 606 are presented within Other Income and are recognized as revenue as the Company satisfies its obligation to the customer. Services within the scope of ASC 606 include income from fiduciary activities, service charges on deposit accounts, other service income, checkcard fee income, ATM fees, and gain on sale of OREO, net. The adoption of this guidance on January 1, 2018 did not have a material impact on Park's consolidated financial statements. However, the adoption of this standard resulted in additional disclosures beginning with the first quarter 2018 Form 10-Q. Reference Note 19, Revenue from Contracts with Customers, for further discussion on the Company's accounting policies for revenue sources within the scope of ASC 606.

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 reflected in 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, this ASU clarifies guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale ("AFS") 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 on January 1, 2018 resulted in an $1.9 million increase to beginning retained earnings and a $995,000 increase to beginning accumulated other comprehensive loss. Additional income of $3.2 million and $1.3 million was recorded in the first and second quarters of 2018, respectively, as a result of changes to the accounting for equity investments. Further, beginning with the first quarter of 2018, Park's fair value disclosures in Note 14, Fair Value, have incorporated the revised disclosure requirements for financial investments.

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 then current GAAP was either unclear or did 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.  The adoption of this guidance on January 1, 2018 did not have an impact on Park's consolidated financial statements. As such transactions arise, management will utilize the updated guidance in providing disclosures within Park’s consolidated condensed statements of cash flows. 

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. As a result of the adoption of this guidance on January 1, 2018, all prior periods have been recast to separately record the service cost component and other components of net benefit cost. For all periods presented, this resulted in an increase in other income and an offsetting increase in other expense with no change to net income. See Note 12, Benefit Plans, for further details.

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 concerning which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting under Topic 718. 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 on January 1, 2018 did not impact Park's consolidated financial statements.

ASU 2017-12 - Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities: In August 2017, the FASB issued ASU 2017-12 - Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. This ASU amends the current guidance with the objective of improving the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities in its financial statements. In addition, this ASU amends the current guidance to simplify the application of the hedge accounting guidance. 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 early adoption of this guidance on July 1, 2018 did not have an impact on Park's consolidated financial statements. Park will apply this guidance to future transactions.

ASU 2018-02 - Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income: In February 2018, the FASB issued ASU 2018-02 -Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This ASU allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects, resulting from the newly - enacted federal corporate income tax rate. The amount of the reclassification is the difference between the historical federal corporate income tax rate and the newly-enacted 21% federal corporate income tax rate. The 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 early adoption of this guidance effective January 1, 2018 resulted in a $3.8 million increase to Park's accumulated other comprehensive loss and a $3.8 million increase to retained earnings.

ASU 2018-03 - Technical Corrections and Improvements to Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. In February 2018, the FASB issued ASU 2018-03 - Technical Corrections and Improvements to Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. This ASU includes amendments that clarify certain aspects of the guidance issued in ASU 2016-01. Park considered this clarification in determining the appropriate adoption of ASU 2016-01 effective as of January 1, 2018.

Issued But Not Yet Effective Accounting Standards

ASU 2016-02 - Leases (Topic 842): In February 2016, the FASB issued ASU 2016-02 - Leases (Topic 842). This 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 2016-13 - 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 ("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 model requires an entity to estimate 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 the CECL model and is currently in the process of implementing a software solution to assist in implementing the adoption of this ASU. Management plans to run our current allowance model and a CECL model concurrently for 12 months prior to the adoption of this guidance on January 1, 2020.

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.

The following table summarizes the impact of retrospective application of this ASU to the consolidated condensed statement of income for the three and six months ended June 30, 2017.

Assets And Liabilities Measured At Fair Value On A Nonrecurring Basis

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.
