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 period ended March 31, 2017 are not necessarily indicative of the operating results to be anticipated for the fiscal year ending December 31, 2017.

The accompanying unaudited consolidated condensed financial statements have been prepared in accordance with the instructions for Form 10-Q and, therefore, do not include all information and footnotes necessary for a fair presentation of the condensed balance sheets, condensed statements of income, condensed statements of comprehensive income, condensed statements of changes in shareholders’ equity and condensed statements of cash flows in conformity with United States ("U.S.") generally accepted accounting principles (“U.S. GAAP”). These financial statements should be read in conjunction with the consolidated financial statements incorporated by reference in the Annual Report on Form 10-K of Park for the fiscal year ended December 31, 2016 from Park’s 2016 Annual Report to Shareholders (“Park's 2016 Annual Report”). Certain prior period amounts have been reclassified to conform to the current period presentation.

Park’s significant accounting policies are described in Note 1 of the Notes to Consolidated Financial Statements included in Park’s 2016 Annual Report. For interim reporting purposes, Park follows the same basic accounting policies, as updated by the information contained in this report, and considers each interim period an integral part of an annual period.

Note 2 – Recent Accounting Pronouncements

ASU 2014-09 - Revenue from Contracts with Customers (Topic 606): In May 2014, the Financial Accounting Standards Board (the "FASB") issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). The ASU creates a new topic, Topic 606, to provide guidance on revenue recognition for entities that enter into contracts with customers to transfer goods or services or enter into contracts for the transfer of nonfinancial assets. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Additional disclosures are required to provide quantitative and qualitative information regarding the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The new guidance is effective for annual reporting periods, and interim reporting periods within those annual periods, beginning after December 15, 2017. While interest income is specifically out of scope of this guidance, management is currently evaluating the revenue streams within "Other income" to assess the applicability of this guidance. Specifically, management is evaluating the impact of this new guidance on deposit fees recorded within "Service charges on deposit accounts" and trust income within "Income from fiduciary activities."

ASU 2016-01 - Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. In January 2016, the FASB issued ASU 2016-01 - Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. Changes to the current U.S. GAAP model primarily affect the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. In addition, the ASU clarifies guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale securities. The new guidance is effective for annual reporting periods and interim reporting periods within those annual periods, beginning after December 15, 2017. The adoption of this guidance is not expected to have a material impact on Park's consolidated financial statements.

ASU 2016-02 - Leases (Topic 842): In February 2016, the FASB issued ASU 2016-02 - Leases (Topic 842). The ASU will require all organizations that lease assets to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. Additional qualitative and quantitative disclosures will be required so that users can understand more about the nature of an entity’s leasing activities. The new guidance is effective for annual reporting periods and interim reporting periods within those annual periods, beginning after December 15, 2018. Early adoption is permitted. Management is currently analyzing data on leased assets. The adoption of this guidance is expected to increase both assets and liabilities, but is not expected to have a material impact on Park's consolidated statement of income.

10

ASU 2016-09 - Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting: In March 2016, FASB issued ASU 2016-09 - Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The ASU provides simplification for several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The new guidance was effective for annual reporting periods and interim reporting periods within those annual periods, beginning after December 15, 2016. Early adoption was permitted. The adoption of this guidance on January 1, 2017 did not have a material impact on Park's consolidated financial statements.

ASU 2016-13 - Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments: In June 2016, FASB issued ASU 2016-13 - Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The new guidance replaces the incurred loss model with an expected loss model, which is referred to as the current expected credit loss ("CECL") model. The CECL model is applicable to the measurement of credit losses on financial assets measured at amortized cost, including loan receivables, held-to-maturity debt securities, and reinsurance receivables. It also applies to off-balance sheet credit exposures not accounted for as insurance (loan commitments, standby letters of credit, financial guarantees, and other similar instruments) and net investments in leases recognized by a lessor. The CECL model requires an entity to estimate the credit losses over the life of an asset or off-balance sheet exposure. The new guidance is effective for annual reporting periods and interim reporting periods within those annual periods, beginning after December 15, 2019. Early adoption is permitted for annual reporting periods and interim reporting periods within those annual periods, beginning after December 15, 2018.

Management is currently evaluating the impact of the adoption of this guidance on Park's consolidated financial statements. We anticipate that the adoption of the CECL model will result in a material increase to Park's allowance for loan losses. Management has established a committee to oversee the implementation of CECL. This committee is currently assessing the data and system requirements necessary for adoption. Management plans to run our current incurred loss model and a CECL model concurrently for 12 months prior to the adoption of this guidance on January 1, 2020.

ASU 2016-15 - Statement of Cash Flows (Topic 203): Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force):  In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 203): Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force).  This ASU provides guidance on eight specific cash flow issues where current U.S. GAAP is either unclear or does not include specific guidance. The new guidance is effective for annual reporting periods, and interim reporting periods within those annual periods, beginning after December 15, 2017.  As such transactions arise, management will utilize the updated guidance within Park’s consolidated statements of cash flows. 

ASU 2017-04 - Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment:  In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This ASU eliminates Step 2 from the goodwill impairment test. Instead, under the new guidance, an entity is to perform its annual goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge would be recognized for the amount by which the carrying amount exceeds the reporting unit's fair value. The new guidance is effective for annual reporting periods, and interim reporting periods within those annual periods, beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of this guidance is not expected to have an impact on Park's consolidated financial statements.

ASU 2017-07 - Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost: In March 2017, the FASB issued ASU 2017-07 - Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This ASU requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component. The new guidance is effective for annual reporting periods, and interim reporting periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted for interim or annual periods. The adoption of this guidance is not expected to have a material impact on Park's consolidated financial statements.

ASU 2017-08 - Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities: In March 2017, the FASB issued ASU 2017-08 - Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. This ASU amends the amortization period for certain purchased callable debt securities held at a premium. It shortens the amortization period for the premium to the earliest call date. Under current U.S. GAAP, premiums on callable debt securities generally are amortized to the

11

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 March 31, 2017 and December 31, 2016, there were $17.4 million and $24.7 million, respectively, of partial charge-offs on loans individually evaluated for impairment with no related allowance recorded and $6.3 million and $0.2 million, respectively, of partial charge-offs on loans individually evaluated for impairment that also had a specific reserve allocated.

14

 The allowance for loan losses included specific reserves related to loans individually evaluated for impairment at March 31, 2017 and December 31, 2016 of $1.1 million and $0.5 million, respectively. These loans with specific reserves had a recorded investment of $3.3 million and $2.1 million as of March 31, 2017 and December 31, 2016, respectively.

Interest income on nonaccrual loans individually evaluated for impairment is recognized on a cash basis only when Park expects to receive the entire recorded investment of the loan. Interest income on accruing TDRs individually evaluated for impairment continues to be recorded on an accrual basis. 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 months ended March 31, 2017 and March 31, 2016:

Credit Quality Indicators

Management utilizes past due information as a credit quality indicator across the loan portfolio. Past due information as of March 31, 2017 and December 31, 2016 is included in the tables above. The past due information is the primary credit quality indicator within the following classes of loans: (1) mortgage loans and installment loans in the construction real estate segment; (2) mortgage loans, HELOC and installment loans in the residential real estate segment; and (3) consumer loans. The primary credit indicator for commercial loans is based on an internal grading system that grades commercial loans on a scale from 1 to 8. Credit grades are continuously monitored by the responsible loan officer and adjustments are made when appropriate. A grade of 1 indicates little or no credit risk and a grade of 8 is considered a loss. Commercial loans that are pass-rated (graded an 1 through a 4) are considered to be of acceptable credit risk. Commercial loans graded a 5 (special mention) are considered to be watch list credits and a higher loan loss reserve percentage is allocated to these loans. Loans classified as special mention have potential weaknesses that require management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of Park’s credit position at some future date. Commercial loans graded 6 (substandard), also considered to be watch list credits, are considered to represent higher credit risk and, as a result, a higher loan loss reserve percentage is allocated to these loans. Loans classified as substandard are inadequately protected by the current sound worth and paying capacity of the obligor or the value of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that Park will sustain some loss if the deficiencies are not corrected. Commercial loans that are graded a 7 (doubtful) are shown as nonaccrual and Park generally charges these loans down to their fair value by taking a partial charge-off or recording a specific reserve. Loans classified as doubtful have all the weaknesses inherent in those classified as substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Certain 6-rated loans and all 7-rated loans are placed on nonaccrual status and included within the impaired category. A loan is deemed impaired when management determines the borrower's ability to perform in accordance with the contractual loan agreement is in doubt. Any commercial loan graded an 8 (loss) is completely charged off.

Troubled Debt Restructurings ("TDRs")

Management classifies loans as TDRs when a borrower is experiencing financial difficulties and Park has granted a concession to the borrower as part of a modification or in the loan renewal process. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of the borrower's debt in the foreseeable future without the modification. This evaluation is performed in accordance with the Company’s internal underwriting policy. Management’s policy is to modify loans by extending the term or by granting a temporary or permanent contractual interest rate below the market rate, not by forgiving debt. A court's discharge of a borrower's debt in a Chapter 7 bankruptcy is considered a concession when the borrower does not reaffirm the discharged debt.

Certain loans which were modified during the three-month periods ended March 31, 2017 and March 31, 2016 did not meet the definition of a TDR as the modification was a delay in a payment that was considered to be insignificant. Management considers a forbearance period of up to three months or a delay in payment of up to 30 days to be insignificant. TDRs may be classified as accruing if the borrower has been current for a period of at least six months with respect to loan payments and management expects that the borrower will be able to continue to make payments in accordance with the terms of the restructured note. Management reviews all accruing TDRs quarterly to ensure payments continue to be made in accordance with the modified terms.

17

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 as the borrower has complied with the terms of the loan at the date of the renewal/modification and there was a reasonable expectation that the borrower would continue to comply with the terms of the loan subsequent to the date of the renewal/modification. The majority of these TDRs were originally considered restructurings in a prior year as a result of a renewal/modification with an interest rate that was not commensurate with the risk of the underlying loan at the time of the renewal/modification. There were no TDR classifications removed during the three-month period ended March 31, 2017. The TDR classification was removed on $806,000 of loans during the three-month period ended March 31, 2016, respectively.

At March 31, 2017 and December 31, 2016, there were $47.8 million and $46.9 million, respectively, of TDRs included in the nonaccrual loan totals. At March 31, 2017 and December 31, 2016, $40.2 million and $38.0 million, respectively, of these nonaccrual TDRs were performing in accordance with the terms of the restructured note. As of March 31, 2017 and December 31, 2016, loans with a recorded investment of $21.2 million and $18.2 million, respectively, were included in accruing TDR loan totals. Management will continue to review the restructured loans and may determine it appropriate to move certain nonaccrual TDRs to accrual status in the future.

At March 31, 2017 and December 31, 2016, Park had commitments to lend $1.1 million and $0.7 million, respectively, of additional funds to borrowers whose outstanding loan terms had been modified in a TDR.

There were $0.5 million and $0.2 million of specific reserves related to TDRs at March 31, 2017 and December 31, 2016, respectively. Modifications made in 2016 and 2017 were largely the result of renewals and extending the maturity date of the loan at terms consistent with the original note. These modifications were deemed to be TDRs primarily due to Park’s conclusion that the borrower would likely not have qualified for similar terms through another lender. Many of the modifications deemed to be TDRs were previously identified as impaired loans, and thus were also previously evaluated for impairment under Accounting Standards Codification (ASC) 310.  Additional specific reserves of $280,000 and $25,000 were recorded during the three-month periods ended March 31, 2017 and March 31, 2016, respectively, as a result of TDRs identified in the respective periods.

The terms of certain other loans were modified during the three-month periods ended March 31, 2017 and March 31, 2016 that did not meet the definition of a TDR. Modified substandard commercial loans which did not meet the definition of a TDR had a total recorded investment as of March 31, 2017 of $113,000. There were no modified substandard commercial loans which did not meet the definition of a TDR at March 31, 2016. 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 loan such that the modification was deemed to be at market terms.  Modified consumer loans which did not meet the definition of a TDR had a total recorded investment of $1.4 million and $2.0 million, as of March 31, 2017 and March 31, 2016, respectively. Many of these loans were to borrowers who were not experiencing financial difficulties but who were looking to reduce their cost of funds.

18

The following tables detail the number of contracts modified as TDRs during the three-month periods ended March 31, 2017 and March 31, 2016, as well as the recorded investment of these contracts at March 31, 2017 and March 31, 2016. The recorded investment pre- and post-modification is generally the same due to the fact that Park does not typically provide for forgiveness of principal.

Of those loans which were modified and determined to be a TDR during the three-month period ended March 31, 2017, $2.6 million were on nonaccrual status as of December 31, 2016. Of those loans which were modified and determined to be a TDR during the three-month period ended March 31, 2016, $922,000 were on nonaccrual status as of December 31, 2015.

The following tables present the recorded investment in financing receivables which were modified as TDRs within the previous 12 months and for which there was a payment default during the three-month periods ended March 31, 2017 and March 31, 2016, respectively. For these tables, a loan is considered to be in default when it becomes 30 days contractually past due under the modified terms. The additional allowance for loan loss resulting from the defaults on TDR loans was immaterial.

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 2016 Annual Report.

Loss factors are reviewed quarterly and updated at least annually to reflect recent loan loss history and incorporate current risk and trends which may not be recognized in historical data. Several enhancements were made in the third quarter of 2016 as a result of management's quarterly review.

• Management updated the historical loss calculation during the third quarter of 2016, incorporating annualized net charge-offs plus changes in specific reserves through September 30, 2016. Additionally, management removed net charge-offs plus changes in specific reserves for the year ended December 31, 2009. Management's belief has been that historical losses should encompass the complete economic cycle. However, given the extended length of the recovery, management determined that 2009 data was no longer reflective of the current portfolio. Management has taken the look back period into consideration in the quarterly evaluation of environmental loss factors.

• As part of this mid-year historical loss update, management determined that it was no longer appropriate to more heavily weight those years with higher losses in the historical loss calculation and applied equal percentages to each of the years in this calculation. The trends that existed when management adopted this weighting no longer appear to exist, resulting in the adjustment back to equal weightings of all years evaluated.

• As part of the normal quarterly process, management reviewed and updated the environmental loss factors applied to the commercial portfolio in order to incorporate changes in the macroeconomic environment. Additionally, management updated the calculation of the loss emergence period utilizing a more granular process.

20

The impact of the changes described above resulted in a decrease of $3.8 million in the ALLL at September 30, 2016, compared to what the ALLL would have been had the calculation, and related assumptions, used at June 30, 2016 remained constant.

The historical loss factors were updated again in the fourth quarter of 2016 to incorporate losses through December 31, 2016. As part of the normal quarterly process, during the first quarter of 2017, management reviewed and updated the environmental loss factors applied to the commercial portfolio in order to incorporate changes in the macroeconomic environment.

The activity in the allowance for loan losses for the three months ended March 31, 2017 and March 31, 2016 is summarized below.

Loans collectively evaluated for impairment in the following tables include all performing loans at March 31, 2017 and December 31, 2016, 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 March 31, 2017 and December 31, 2016, 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 2016 Annual Report).

The reconciling amounts for consolidated total assets for the periods ended March 31, 2017 and 2016 consisted of the elimination of intersegment borrowings and the assets of the Parent Company which were not eliminated.

Note 8 – Loans Held For Sale

Mortgage loans held for sale are carried at their fair value. At March 31, 2017 and December 31, 2016, respectively, Park had approximately $6.7 million and $10.4 million in mortgage loans held for sale. These amounts are included in loans on the consolidated condensed balance sheets and in the residential real estate loan segments in Note 3 and Note 4. The contractual balance was $6.6 million and $10.3 million at March 31, 2017 and December 31, 2016, respectively. The gain expected upon sale was $86,000 and $131,000 at March 31, 2017 and December 31, 2016, respectively. None of these loans were 90 days or more past due or on nonaccrual status as of March 31, 2017 or December 31, 2016.

Note 9 – Investment Securities

The amortized cost and fair value of investment securities are shown in the following tables. Management performs a quarterly evaluation of investment securities for any other-than-temporary impairment.

Management does not believe any of the unrecognized losses at March 31, 2017 or December 31, 2016 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 March 31, 2017, are shown in the following table by contractual maturity, except for asset-backed securities, which are shown as a single total, due to the unpredictability of the timing of principal repayments. 

Securities Available-for-Sale (In thousands)	Amortized cost		Fair value		Tax equivalent yield
Obligations of U.S. Treasury and other U.S. Government sponsored entities' obligations:

(1) The tax equivalent yield for obligations of state and political subdivisions includes the effects of a taxable equivalent adjustment using a 35% rate. The aggregate taxable equivalent adjustment was $786,000 for the three months ended March 31, 2017.

27

All of Park’s securities shown in the table above as obligations of U.S. Treasury and other U.S. Government sponsored entities' notes are callable notes. These callable notes have final maturities of 0.6 years to 3 years. Of the $268.4 million reported at March 31, 2017, none were expected to be called. The remaining average life of the entire investment portfolio is estimated to be 4.4 years.

There were no sales of investment securities during the three-month periods ended March 31, 2017 or 2016.

Note 11 - Share-Based Compensation

The Park National Corporation 2013 Long-Term Incentive Plan (the "2013 Incentive Plan") was adopted by the Board of Directors of Park on January 28, 2013 and was approved by Park's shareholders at the Annual Meeting of Shareholders on April 22, 2013. The 2013 Incentive Plan makes equity-based awards and cash-based awards available for grant to participants in the form of incentive stock options, nonqualified stock options, stock appreciation rights, restricted common shares, restricted stock unit awards that may be settled in common shares, cash or a combination of the two, unrestricted common shares and cash-based awards. Under the 2013 Incentive Plan, 600,000 common shares are authorized to be delivered in connection with grants under the 2013 Incentive Plan. The common shares to be delivered under the 2013 Incentive Plan may consist of either common shares currently held or common shares subsequently acquired by Park as treasury shares, including common shares purchased in the open market or in private transactions. No awards may be made under the 2013 Incentive Plan after April 22, 2023. At March 31, 2017, 429,889 common shares were available for future grants under the 2013 Incentive Plan.

During the three months ended March 31, 2017 and 2016, the Compensation Committee of the Board of Directors of Park granted awards of performance-based restricted stock units ("PBRSUs") covering an aggregate of 45,788 and 41,550 common shares, respectively, to certain employees of Park and its subsidiaries. The number of PBRSUs earned or settled will depend on the level of achievement with respect to certain performance criteria and are also subject to subsequent service-based vesting.

A summary of changes in the common shares subject to nonvested PBRSUs for the three months ended March 31, 2017 follows:

	Common shares subject to PBRSUs
Nonvested at January 1, 2017	85,425
Granted	45,788
Vested	9,674
Forfeited	150
Adjustment for performance conditions of PBRSUs (1)	(1,802	)
Nonvested at March 31, 2017	119,587

(1) The number of PBRSUs earned depends on the level of achievement with respect to certain performance criteria. Adjustment herein represents the difference between the maximum number of common shares which could be earned and the actual number earned for those PBRSUs as to which the performance period was completed.

28

On March 31, 2017, 9,674 PBRSUs granted in 2014 vested. A total of 3,293 common shares were withheld to pay employee income taxes. This resulted in a net amount of 6,381 common shares being issued to employees of Park.

Share-based compensation expense of $826,000 and $468,000 was recognized for the three-month periods ended March 31, 2017 and 2016, respectively.

The following table details expected additional share-based compensation expense related to PBRSUs currently outstanding:

Note 12 – Pension Plan

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 periods ended March 31, 2017 and 2016.

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

Note 13 – Loan Servicing

Park serviced sold mortgage loans of $1.33 billion at each of March 31, 2017 and December 31, 2016 and $1.27 billion at March 31, 2016. At March 31, 2017, $3.6 million of the sold mortgage loans were sold with recourse, compared to $4.1 million at December 31, 2016 and $4.9 million at March 31, 2016. Management closely monitors the delinquency rates on the mortgage loans sold with recourse. At March 31, 2017 and December 31, 2016, management had established reserves of $287,000 and $266,000, respectively, to account for expected losses on loan repurchases.

When Park sells mortgage loans with servicing rights retained, servicing rights are initially recorded at fair value. Park selected the “amortization method” as permissible within U.S. GAAP, whereby the servicing rights capitalized are amortized in proportion to and over the period of estimated future servicing income of the underlying loan. At the end of each reporting period, the carrying value of mortgage servicing rights (“MSRs”) is assessed for impairment with a comparison to fair value. MSRs are carried at the lower of their amortized cost or fair value.

Servicing fees included in other service income were $0.9 million for the three months ended March 31, 2017 and $0.8 million for the same period of 2016.

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 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 the three months ended March 31, 2017 or 2016. Management’s policy is to transfer assets or liabilities from one level to another when the methodology to obtain the fair value changes such that there are more or fewer unobservable inputs as of the end of the reporting period.

The following methods and assumptions were used by the Company in determining the fair value of the financial assets and liabilities discussed above:

Investment securities: Fair values for investment securities are based on quoted market prices, where available. If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments. For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows.

Fair value swap: The fair value of the swap agreement entered into with the purchaser of the Visa Class B shares represents an internally developed estimate of the exposure based upon probability-weighted potential Visa litigation losses.

31

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

Mortgage loans held for sale: Mortgage loans held for sale are carried at their fair value. Mortgage loans held for sale are estimated using security prices for similar product types and, therefore, are classified in Level 2.

The tables below are a reconciliation of the beginning and ending balances of the Level 3 inputs for the three months ended March 31, 2017 and 2016, 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, real estate appraisals, income approach appraisals, and lot development loan appraisals, received by the Company. These are discussed below:

• Real estate appraisals typically incorporate measures such as recent sales prices for comparable properties. Appraisers may make adjustments to the sales prices of the comparable properties as deemed appropriate based on the age, condition or general characteristics of the subject property. Management generally applies a 15% discount to real

32

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 March 31, 2017 and 2016 was $0.3 million and $0.6 million, respectively.

MSRs totaled $9.3 million at March 31, 2017. Of this $9.3 million MSR carrying balance, $6.9 million was recorded at fair value and included a valuation allowance of $0.7 million. The remaining $2.4 million was recorded at cost, as the fair value of the MSRs exceeded cost at March 31, 2017. At December 31, 2016, MSRs totaled $9.3 million. Of this $9.3 million MSR carrying balance, $6.8 million was recorded at fair value and included a valuation allowance of $0.7 million. The remaining $2.5 million was recorded at cost, as the fair value exceeded cost at December 31, 2016. The income related to MSRs carried at fair value during the three months ended March 31, 2017 was $59,000. There was no income or expense related to MSRs carried at fair value during the three months ended March 31, 2016.

Total OREO held by Park at March 31, 2017 and December 31, 2016 was $13.7 million and $13.9 million, respectively. Approximately 50% of OREO held by Park at each of March 31, 2017 and December 31, 2016 was carried at fair value due to fair value adjustments made subsequent to the initial OREO measurement. At March 31, 2017 and December 31, 2016, OREO held at fair value, less estimated selling costs, amounted to $6.8 million and $6.9 million, respectively. The net expense related

34

to OREO fair value adjustments was $73,000 and $118,000 for the three-month periods ended March 31, 2017 and 2016, respectively.

The following methods and assumptions were used by Park in estimating its fair value disclosures for assets and liabilities not discussed above:

Cash and cash equivalents:The carrying amounts reported in the consolidated condensed balancesheets for cash and short-term instruments approximate those assets’ fair values.

Other investments: FHLB and FRB stock within "Other investments" are carried at their respective redemption values as it is not practical to calculate their fair values. Additional investments within "Other investments" are carried at their cost basis as these investments do not have a readily determinable fair value and Park does not have the ability to influence the operating or financial decisions of the investee.

Loans receivable:For variable-rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values. The fair values for certain mortgage loans (e.g., one-to-four family residential) are based on quoted market prices of similar loans sold in conjunction with securitization transactions, adjusted for differences in loan characteristics. The fair values for other loans are estimated using discounted cash flow analyses, based upon interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. The methods utilized to estimate the fair value do not necessarily represent an exit price.

Off-balance sheet instruments:Fair values for Park’s loan commitments and standby letters of credit are based on the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing. The carrying amount and fair value are not material.

Deposit liabilities:The fair values disclosed for demand deposits (e.g., interest and non-interest checking, savings, and money market accounts) are, by definition, equal to the amounts payable on demand at the reporting date (i.e., their carrying amounts). The carrying amounts for variable-rate, fixed-term certificates of deposit approximate their fair values at the reporting date. Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities of time deposits.

Short-term borrowings:The carrying amounts of federal funds purchased, borrowings under repurchase agreements and other short-term borrowings approximate their fair values.

Long-term debt:Fair values for long-term debt are estimated using a discounted cash flow calculation that applies interest rates currently being offered on long-term debt to a schedule of monthly maturities.

Subordinated notes:Fair values for subordinated notes are estimated using a discounted cash flow calculation that applies interest rate spreads currently being offered on similar debt structures to a schedule of monthly maturities.

Note 16 – Investment in Qualified Affordable Housing

Park makes certain equity investments in various limited partnerships that sponsor affordable housing projects. The purposes of these investments are to achieve a satisfactory return on capital, help create affordable housing opportunities, and assist the Company to achieve our goals associated with the Community Reinvestment Act.

The table below details the balances of Park’s affordable housing tax credit investments and related unfunded commitments as of March 31, 2017 and December 31, 2016.

(in thousands)	March 31, 2017		December 31, 2016
Affordable housing tax credit investments	$	51,083	$	52,947
Unfunded commitments	14,282		14,282

Commitments are funded when capital calls are made by the general partner. Park expects that the current commitments will be funded between 2017 and 2027.

During the three months ended March 31, 2017 and 2016, Park recognized amortization expense of $1.9 million and $1.8 million, respectively, which was included within the provision for income taxes. Additionally, during the three months ended March 31, 2017 and 2016, Park recognized tax credits and other benefits from its affordable housing tax credit investments of $2.4 million and $2.3 million, respectively.

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. Park's repurchase agreements with a third-party financial institution are classified as long-term debt on the consolidated condensed balance sheets.

40

All repurchase agreements are subject to terms and conditions of repurchase/security agreements between Park and the client and are accounted for as secured borrowings. Park's repurchase agreements reflected in short-term borrowings consisted of customer accounts and securities which are pledged on an individual security basis.

At March 31, 2017 and December 31, 2016, Park's repurchase agreement borrowings totaled $520 million and $510 million, respectively. At both March 31, 2017 and December 31, 2016, $300 million of Park's repurchase agreement borrowings were classified as long-term debt with the remaining amount being classified as short-term debt on the consolidated condensed balance sheets. These borrowings were collateralized with U.S. government and agency securities with a carrying value of $594 million and $569 million at March 31, 2017 and December 31, 2016, respectively. Declines in the value of the collateral would require Park to pledge additional securities. As of March 31, 2017 and December 31, 2016, Park had $570 million and $640 million, respectively, of available unpledged securities.

The table below shows the remaining contractual maturity of repurchase agreements by collateral pledged at March 31, 2017 and December 31, 2016:

	March 31, 2017
(in thousands)	Remaining Contractual Maturity of the Agreements
	Overnight and Continuous		Up to 30 days		30 - 90 days		Greater than 90 days		Total
U.S. government and agency securities	$	218,759	$	—	$	—	$	301,104	$	519,863
	December 31, 2016
(in thousands)	Remaining Contractual Maturity of the Agreements
	Overnight and Continuous		Up to 30 days		30 - 90 days		Greater than 90 days		Total
U.S. government and agency securities	$	208,691	$	—	$	—	$	301,104	$	509,795

On November 30, 2012, Park restructured $300 million in repurchase agreements with a third-party financial institution and paid a $25 million prepayment penalty. The penalty is included in long-term debt and is being amortized as an adjustment to interest expense over the remaining term of the repurchase agreements using the effective interest method. Of the $25 million prepayment penalty, $3.5 million and $4.7 million remained unamortized as of March 31, 2017 and December 31, 2016, respectively.

Note 18 – Contingent Liabilities

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 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 March 31, 2017, the Company had accrued charges of approximately $2.3 million for legal contingencies related to various legal and other adversary proceedings.

Note 19 – Subsequent Events

On April 24, 2017, Park prepaid in full the $30.0 million outstanding aggregate principal amount of the 7% Subordinated Notes due April 20, 2022 (the "2012 Notes"), plus accrued interest on the 2012 Notes in the aggregate amount of $140,000. The 2012 Notes were originally issued on April 20, 2012 to 56 purchasers, all of whom were accredited investors. April 21, 2017 was the earliest repayment date allowable under terms of the Note Purchase Agreement, dated April 20, 2012, under which the 2012 Notes were originally issued.

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, including 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 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 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; uncertainty regarding the nature, timing 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, accounting, bank products and services, 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 OCC, the FDIC, and the Federal Reserve Board, to implement the Dodd-Frank Act's provisions, the Budget Control Act of 2011, the American Taxpayer Relief Act of 2012, the JOBS Act, the FAST Act 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 new presidential administration and uncertainty or speculation pending the enactment of such changes; significant changes in the tax laws, which may adversely affect the fair values of net deferred tax assets and obligations of state and political subdivisions held in Park's investment securities portfolio; the effect of trade, monetary, fiscal and other governmental policies of the U.S. federal government, including money supply and interest rate policies of the Federal Reserve Board; disruption in the liquidity and other functioning of U.S. financial markets; the impact on financial markets and the economy of any changes in the credit ratings of the U.S. Treasury obligations and other U.S. government-backed debt, as well as issues surrounding the levels of U.S., European and Asian government debt and concerns regarding the creditworthiness of certain sovereign governments, supranationals and financial institutions in Europe and Asia; the uncertainty surrounding the United Kingdom's exit from the European Union and its consequences; our litigation and regulatory compliance exposure, including any adverse developments in legal proceedings or other claims and unfavorable resolution of regulatory and other governmental examinations or other inquiries; the adequacy of our risk management program; the ability to secure confidential information and deliver products and services through the use of computer systems and telecommunications networks; a failure in or breach of our operational or security systems or infrastructure, or those of our third-party vendors and other service providers, including as a result of cyber attacks; fraud, scams and schemes of third parties; the impact of widespread natural and other disasters, pandemics, dislocations, terrorist activities or international hostilities on the economy and financial markets generally or on us or our counterparties specifically; demand for loans in the respective market areas served by Park and our subsidiaries; and other risk factors relating to the banking industry as detailed from time to time in Park's reports filed with the SEC including those described in "Item 1A. Risk Factors" of Part I of Park's Annual Report on Form 10-K for the fiscal year ended December 31, 2016. Park does not undertake, and specifically disclaims any obligation, to publicly release the results of any revisions that may be made to update any forward-looking statement to reflect the events or circumstances after the date on which the forward-looking statement was made, or reflect the occurrence of unanticipated events, except to the extent required by law.

Critical Accounting Policies

Note 1 of the Notes to Consolidated Financial Statements included in Park’s 2016 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 available-for-sale (“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 relates to the value inherent in the banking industry and that value is dependent upon the ability of Park’s Ohio-based banking 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 2016 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.

43

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.

The category “Parent Company” above excludes the results for SEPH, an entity which is winding down commensurate with the disposition of SEPH's nonperforming assets. Management considers the “Ongoing operations” results, which exclude the results of SEPH, to reflect the business of Park and Park's subsidiaries going forward. The discussion below provides additional information regarding the segments that make up the “Ongoing operations”, followed by additional information regarding SEPH.

The Park National Bank (PNB)

The table below reflects PNB's net income for the first quarters of 2017 and 2016, and for the fiscal years ended December 31, 2016 and 2015.

Net income	$	21,486	$	21,744	$	84,451	$	84,345

Net interest income of $57.5 million for the three months ended March 31, 2017 represented a $325,000, or 0.6% increase, compared to $57.2 million for the same period of 2016. The increase was the result of a $629,000 increase in interest income offset by a $304,000 increase in interest expense.

The $629,000 increase in interest income was due to a $1.0 million increase in interest income on loans, offset by a $405,000 decrease in interest income on investments. The increase in interest income on loans was largely the result of a $231 million, or 4.4%, increase in average loans from $5.0 billion for the three months ended March 31, 2016, to $5.2 billion for the three months ended March 31, 2017. Included in interest income for the three months ended March 31, 2017 was $80,000 in income

45

related to PNB participations in legacy Vision Bank ("Vision") assets, compared to $561,000 for the three months ended March 31, 2016.

The provision for loan losses of $720,000 for the three months ended March 31, 2017 represented an improvement of $813,000, compared to a provision of loan losses of $1.5 million for the same period of 2016. Refer to the “Credit Metrics and Provision for (Recovery of) Loan Losses” section for additional details regarding the level of the provision for loan losses recognized in each period presented above.

Other expense of $43.8 million for the three months ended March 31, 2017 represented an increase of $2.4 million, or 5.9%, compared to $41.4 million for the same period of 2016. The $2.4 million increase was primarily related to a $1.1 million increase in salaries expense, a $511,000 increase in employee benefits expense (largely related to an increase in medical expenses), an increase of $739,000 in data processing fees, an increase of $177,000 in furniture and equipment expense, and an $174,000 increase in insurance expense, offset by a decrease of $310,000 in professional fees and services, and a $224,000 decrease in non-loan related losses which are included in miscellaneous expense.

PNB's results for the first quarters of 2017 and 2016, and for the fiscal year ended December 31, 2016, included income and expense related to participations in legacy Vision assets.

Management actively manages the investment portfolio. The average balance of investment securities may increase as a result of attractive investment opportunities. Likewise, the average balance of investment securities may decrease if management sells investment securities or chooses not to reinvest the cash flow from maturities or investment repayments.

The following table shows the tax equivalent yield on average interest earning assets for the three months ended March 31, 2017 and for the fiscal years ended December 31, 2016, 2015 and 2014.

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 periods ended March 31, 2017 and 2016.

	Three Months Ended March 31,

SEPH	(9.26		)%	(30.80		)%
Park	0.12		%	0.04		%

51

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 March 31, 2017, December 31, 2016 and March 31, 2016.

General reserves as a % of non-impaired loans	0.93		%	0.96		%	1.04		%

The allowance for loan losses of $49.9 million at March 31, 2017 represented a $702,000, or 1.4% decrease, compared to $50.6 million at December 31, 2016. This decrease was the result of a $1.2 million decrease in general reserves due to Park's ongoing evaluation of the allowance for loan losses required to cover probable incurred losses with respect to the Park loan portfolio. This decrease in general reserves was offset by a $543,000 increase in specific reserves.

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; and (4) OREO which results from taking possession of property that served as collateral for a defaulted loan.

Impaired Loans:  Park’s allowance for loan losses includes an allocation for loans specifically identified as impaired under GAAP. At March 31, 2017, 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 a 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 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 March 31, 2017, Park had taken partial charge-offs of $23.7 million related to the $70.1 million of commercial loans considered to be impaired, compared to charge-offs of approximately $24.9 million related to the $70.4 million of impaired commercial loans at December 31, 2016. The table below provides additional information related to the Park impaired commercial loans at March 31, 2017, including those impaired commercial loans at PNB and those impaired Vision commercial loans retained at SEPH.

Allowance for loan losses: 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. Several enhancements were made in the third quarter of 2016 as a result of management's quarterly review.

• Management updated the historical loss calculation during the third quarter of 2016, incorporating annualized net charge-offs plus changes in specific reserves through September 30, 2016. Additionally, management removed net charge-offs plus changes in specific reserves for the year ended December 31, 2009. Management's belief has been that historical losses should encompass the complete economic cycle. However, given the extended length of the recovery, management determined that 2009 data was no longer reflective of the current portfolio. Management has taken the look back period into consideration in the quarterly evaluation of environmental loss factors.

• As part of this mid-year historical loss update, management determined that it was no longer appropriate to more heavily weight those years with higher losses in the historical loss calculation and applied equal percentages to each of the years in this calculation. The trends that existed when management adopted this weighting no longer appear to exist, resulting in the adjustment back to equal weightings of all years evaluated.

• As part of the normal quarterly process, management reviewed and updated the environmental loss factors applied to the commercial portfolio in order to incorporate changes in the macroeconomic environment. Additionally, management updated the calculation of the loss emergence period utilizing a more granular process.

The impact of the changes described above resulted in a decrease of $3.8 million in the ALLL at September 30, 2016, compared to what the ALLL would have been had the calculation, and related assumptions, used at June 30, 2016 remained constant.

54

The historical loss factors were updated again in the fourth quarter of 2016 to incorporate losses through December 31, 2016. As part of the normal quarterly process, during the first quarter of 2017, management reviewed and updated the environmental loss factors applied to the commercial portfolio in order to incorporate changes in the macroeconomic environment.

The allowance for loan losses related to performing commercial loans was $31.3 million or 1.20% of the outstanding principal balance of other accruing commercial loans at March 31, 2017. At March 31, 2017, the coverage level within the commercial loan portfolio was approximately 3.15 years compared to 3.20 years at December 31, 2016. Historical loss experience, defined as charge-offs plus changes in specific reserves, over the 84 month period ended December 31, 2016, for the commercial loan portfolio was 0.39%. This 84-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 1.20% for accruing commercial loans breaks down as follows: pass-rated commercial loans are reserved at 1.19%; special mention commercial loans are reserved at 3.11%; and substandard commercial loans are reserved at 10.73%. The reserve levels for pass-rated, special mention and substandard commercial loans in excess of the 84-month loss experience of 0.39% are due to the following factors which management reviews on a quarterly or annual basis:

• Loss Emergence Period Factor: At least annually, management calculates the loss emergence period for each commercial loan segment. Each loss emergence period is calculated based upon the average period of time it takes from the probable occurrence of a loss event to a credit being moved to nonaccrual status. 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 periods were last updated in the fourth quarter of 2016.

• 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 factors were last updated in the fourth quarter of 2016.

• 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.

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 84 months, through December 31, 2016. 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, etc.). At March 31, 2017, the coverage level within the consumer loan portfolio was approximately 1.92 years compared to 1.95 years at December 31, 2016. Historical loss experience, over the 84-month period ended December 31, 2016, for the consumer loan portfolio was 0.35%.

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.

Income from fiduciary activities, which represents revenue earned from Park’s trust activities, increased by $401,000, or 7.8%, to $5.5 million for the three months ended March 31, 2017, compared to $5.1 million for the same period in 2016. Fiduciary fees charged are generally based on the market value of customer accounts. The average market value for assets under management for the three months ended March 31, 2017 was $4,887 million.

Service charges on deposits decreased by $284,000, or 8.3%, to $3.1 million for the three months ended March 31, 2017, compared to $3.4 million for the same period of 2016. The decrease was primarily related to declines in NSF fee income and the discontinuation of daily overdraft fees related to deposit products.

Fee income earned from origination and sale into the secondary market of long-term, fixed-rate mortgage loans is included within other non-yield related fees in the subcategory “Other service income”. Other service income increased by $230,000, or 8.9%, to $2.8 million for the three months ended March 31, 2017, compared to $2.6 million for the same period in 2016. The increase in other service income was primarily due to an increase in loans originated for sale into the secondary market which increased by $2.1 million for the three months ended March 30, 2017, compared to the same period in 2016.

56

Checkcard fee income, which is generated from debit card transactions, increased by $229,000, or 6.5%, to $3.8 million for the three months ended March 31, 2017, compared to $3.5 million for the same period in 2016. The increase was primarily related to an increase in the volume of debit card transactions which increased by 178,000 transactions or 2.0% for the three months ended March 31, 2017, compared to the same period in 2016.

Miscellaneous income decreased by $334,000, to $617,000 for the three months ended March 31, 2017, compared to $951,000 for the same period in 2016. The decrease was primarily related to a $210,000 one time check card incentive received in 2016.

57

Salaries increased by $1.2 million, or 5.4%, to $22.7 million for the three months ended March 31, 2017, compared to $21.6 million for the same period in 2016. The increase for the three months ended March 31, 2017 was due to an $1.0 million increase in salary expense and a $358,000 increase in share-based compensation expense related to performance-based restricted stock unit awards granted under the 2013 Incentive Plan.

Employee benefit expenses increased by $408,000, or 8.5%, to $5.2 million for the three months ended March 31, 2017, compared to $4.8 million for the same period in 2016. The increase for the three months ended March 31, 2017 was primarily due to an increase in Park's self-insured medical expenses compared to the same period in 2016.

Data processing fees increased by $748,000, or 61.5%, to $2.0 million for the three months ended March 31, 2017, compared to $1.2 million for the same period in 2016. The increase for the three months ended March 31, 2017 was primarily related to an increase in expenses related to the issuance of new chip enabled debit cards and related card costs, plus an increase in debit card transactions.

Professional fees and services decreased by $1.8 million, or 27.6%, to $4.8 million for the three months ended March 31, 2017, compared to $6.7 million for the same period in 2016. The decrease was primarily related to a decrease in legal expenses.

Miscellaneous expense decreased by $3.5 million, or 70.3%, to $1.5 million for the three months ended March 31, 2017, compared to $5.0 million for the same period of 2016.  The decrease was primarily due to the fact that miscellaneous expense for the three months ended March 31, 2016 included $3.5 million in accruals due to the ongoing evaluation of litigation and other proceedings impacting the GFSC subsidiary and the Parent Company.

Income Tax

Federal income tax expense was $7.9 million for the first quarter of 2017, compared to $7.7 million for the first quarter of 2016. The effective federal income tax rate for the first quarter of 2017 was 27.9%, compared to 29.2% for the same period in 2016. The difference between the statutory federal income tax rate of 35% and Park’s effective 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, federal historic preservation tax credits, 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 2017 year will be approximately $8.1 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 March 31, 2017 and December 31, 2016

Changes in Financial Condition

Total assets increased by $277.1 million, or 3.7%, during the first three months of 2017 to $7,745 million at March 31, 2017, compared to $7,468 million at December 31, 2016. This increase was primarily due to the following:

• Cash and cash equivalents increased by $245.3 million to $391.8 million at March 31, 2017, compared to $146.4 million at December 31, 2016. Money market instruments represented the majority of this increase, and were $285.2 million at March 31, 2017, compared to $23.6 million at December 31, 2016.

• Total investment securities decreased by $14.1 million, or 0.9%, to $1,566 million at March 31, 2017, compared to $1,580 million at December 31, 2016.

• Loans increased by $41.8 million, or 0.8%, to $5,314 million at March 31, 2017, compared to $5,272 million at December 31, 2016.

Total liabilities increased by $275.2 million, or 4.1%, during the first three months of 2017 to $7,001 million at March 31, 2017, from $6,725 million at December 31, 2016. This increase was primarily due to the following:

• Total deposits increased by $398.6 million, or 7.2%, to $5,921 million at March 31, 2017, compared to $5,522 million at December 31, 2016. The increase in deposits in the first three months of 2017 was largely the result of the product offering for Promontory's Insured Cash Sweep ("ICS") deposits.

• Short-term borrowings decreased by $174.9 million, or 44.3%, to $219.9 million at March 31, 2017, compared to $394.8 million at December 31, 2016.

• Long-term borrowings increased by $51.6 million, or 7.4%, to $745.8 million at March 31, 2017, compared to $694.3 million at December 31, 2016.

Total shareholders’ equity increased by $1.9 million, or 0.3%, to $744.1 million at March 31, 2017, from $742.2 million at December 31, 2016.

• Retained earnings increased by $5.6 million during the period as a result of net income of $20.3 million, offset by common share dividends of $14.5 million.

• Treasury shares increased by $4.8 million during the period as a result of the repurchase of treasury shares in the total amount of $5.4 million, offset by the issuance of treasury shares of $0.6 million.

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 $23.1 million and $12.9 million for the three months ended March 31, 2017 and 2016, respectively. Net income was the primary source of cash from operating activities for each of the three months ended March 31, 2017 and 2016.

Cash used in investing activities was $31.3 million for the three months ended March 31, 2017 and cash provided by investing activities was $85.4 million for the three months ended March 31, 2016. Proceeds from the sale, repayment, or maturity of securities provide cash and purchases of securities use cash. Net securities transactions provided cash of $15.4 million for the three months ended March 31, 2017 and $77.2 million for the three months ended March 31, 2016. Another major use or source of cash in investing activities is the net increase or decrease in the loan portfolio. Cash used by the net increase in the loan portfolio was $46.1 million and cash provided by the net decrease in the loan portfolio was $10.5 million for the three months ended March 31, 2017 and 2016, respectively.

Cash provided by financing activities was $253.5 million for the three months ended March 31, 2017 and $70.1 million for the three months ended March 31, 2016. A major source of cash for financing activities is the net change in deposits. Deposits increased and provided $398.6 million and $259.1 million of cash for the three months ended March 31, 2017 and 2016, respectively. Another major source of cash from financing activities is borrowings in the form of short-term borrowings and

59

long-term debt. For the three months ended March 31, 2017, net short-term borrowings decreased and used $174.9 million in cash and net long-term borrowings increased and provided $50.0 million in cash. For the three months ended March 31, 2016, net short-term borrowings decreased and used $174.6 million in cash and net long-term borrowings remained unchanged. Finally, cash declined by $14.4 million for each of the three months ended March 31, 2017 and 2016, 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, Federal Home Loan Bank borrowings, the capability to securitize or package loans for sale, and a $10.0 million revolving line of credit with another financial institution, which did not have an outstanding balance as of March 31, 2017. The Corporation’s loan to asset ratio was 68.61% at March 31, 2017, compared to 70.60% at December 31, 2016 and 68.15% at March 31, 2016. Cash and cash equivalents were $391.8 million at March 31, 2017, compared to $146.4 million at December 31, 2016 and $317.9 million at March 31, 2016. 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 March 31, 2017 was $744.1 million, or 9.6% of total assets, compared to $742.2 million, or 9.9% of total assets, at December 31, 2016 and $729.7 million, or 9.8% of total assets, at March 31, 2016.

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 available-for-sale 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. 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 2017 is 1.25%. The amounts shown below as the adequately capitalized ratio plus capital conservation buffer includes the fully phased-in 2.50% buffer.

PNB met each of the well capitalized ratio guidelines at March 31, 2017. The following table indicates the capital ratios for PNB and Park at March 31, 2017 and December 31, 2016.

	As of March 31, 2017

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 2016 Annual Report (Table 36) for disclosure concerning contractual obligations and commitments at December 31, 2016. There were no significant changes in contractual obligations and commitments during the first three months of 2017.

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)	March 31, 2017		December 31, 2016
Loan commitments	$	938,364	$	912,007
Standby letters of credit	$	12,872	$	13,746

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 42 of Park’s 2016 Annual Report.

On page 42 (Table 35) of Park’s 2016 Annual Report, management reported that Park’s twelve-month cumulative rate sensitivity gap was a positive (assets exceeding liabilities) $198.6 million or 2.89% of total interest earning assets at December 31, 2016. At March 31, 2017, Park’s twelve-month cumulative rate sensitivity gap was a positive (assets exceeding liabilities) $332.9 million or 4.64% 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 42 of Park’s 2016 Annual Report, management reported that at December 31, 2016, the earnings simulation model projected that net income would decrease by 1.9% using a rising interest rate scenario and decrease by 6.3% using a declining interest rate scenario over the next year. At March 31, 2017, the earnings simulation model projected that net income would decrease by 2.4% using a rising interest rate scenario and would decrease by 5.3% in a declining interest rate scenario. At March 31, 2017, 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 March 31, 2017, that have materially affected, or are reasonably likely to materially affect, Park’s internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1.       Legal Proceedings

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 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 March 31, 2017, the Company had accrued charges of approximately $2.3 million for legal contingencies related to various legal and other adversary proceedings.

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, 2016 (the “2016 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 2016 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.

63

Period	Total number of common shares purchased	Average price paid per common share		Total number of common shares purchased as part of publicly announced plans or programs (1)	Maximum number of common shares that may yet be purchased under the plans or programs (2)
January 1 through January 31, 2017	—	$	—	—	988,050

Total	50,000	$	108.48	50,000	938,050

(1) Common shares were purchased for the purpose of funding the 2013 Incentive Plan.

(2) 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 2013 Incentive Plan which became effective on April 22, 2013 and Park's publicly announced 2017 stock repurchase authorization which became effective on January 23, 2017.

At the 2013 Annual Meeting of Shareholders held on April 22, 2013, Park's shareholders approved the 2013 Incentive Plan. The aggregate number of common shares with respect to which awards may be granted under the 2013 Incentive Plan will be 600,000. The common shares to be issued and delivered under the 2013 Incentive Plan 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 2013 Incentive Plan. On April 22, 2013, Park's Board of Directors authorized the purchase, from time to time, of up to 600,000 Park common shares to be held as treasury shares for subsequent issuance and delivery under the 2013 Incentive Plan.

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 MKT, 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 MKT. 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 2013 Incentive Plan.

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 period ended March 31, 2017 are not necessarily indicative of the operating results to be anticipated for the fiscal year ending December 31, 2017.

The accompanying unaudited consolidated condensed financial statements have been prepared in accordance with the instructions for Form 10-Q and, therefore, do not include all information and footnotes necessary for a fair presentation of the condensed balance sheets, condensed statements of income, condensed statements of comprehensive income, condensed statements of changes in shareholders’ equity and condensed statements of cash flows in conformity with United States ("U.S.") generally accepted accounting principles (“U.S. GAAP”). These financial statements should be read in conjunction with the consolidated financial statements incorporated by reference in the Annual Report on Form 10-K of Park for the fiscal year ended December 31, 2016 from Park’s 2016 Annual Report to Shareholders (“Park's 2016 Annual Report”). Certain prior period amounts have been reclassified to conform to the current period presentation.

Park’s significant accounting policies are described in Note 1 of the Notes to Consolidated Financial Statements included in Park’s 2016 Annual Report. For interim reporting purposes, Park follows the same basic accounting policies, as updated by the information contained in this report, and considers each interim period an integral part of an annual period.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Recent Accounting Pronouncements

Recent Accounting Pronouncements

ASU 2014-09 - Revenue from Contracts with Customers (Topic 606): In May 2014, the Financial Accounting Standards Board (the "FASB") issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). The ASU creates a new topic, Topic 606, to provide guidance on revenue recognition for entities that enter into contracts with customers to transfer goods or services or enter into contracts for the transfer of nonfinancial assets. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Additional disclosures are required to provide quantitative and qualitative information regarding the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The new guidance is effective for annual reporting periods, and interim reporting periods within those annual periods, beginning after December 15, 2017. While interest income is specifically out of scope of this guidance, management is currently evaluating the revenue streams within "Other income" to assess the applicability of this guidance. Specifically, management is evaluating the impact of this new guidance on deposit fees recorded within "Service charges on deposit accounts" and trust income within "Income from fiduciary activities."

ASU 2016-01 - Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. In January 2016, the FASB issued ASU 2016-01 - Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. Changes to the current U.S. GAAP model primarily affect the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. In addition, the ASU clarifies guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale securities. The new guidance is effective for annual reporting periods and interim reporting periods within those annual periods, beginning after December 15, 2017. The adoption of this guidance is not expected to have a material impact on Park's consolidated financial statements.

ASU 2016-02 - Leases (Topic 842): In February 2016, the FASB issued ASU 2016-02 - Leases (Topic 842). The ASU will require all organizations that lease assets to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. Additional qualitative and quantitative disclosures will be required so that users can understand more about the nature of an entity’s leasing activities. The new guidance is effective for annual reporting periods and interim reporting periods within those annual periods, beginning after December 15, 2018. Early adoption is permitted. Management is currently analyzing data on leased assets. The adoption of this guidance is expected to increase both assets and liabilities, but is not expected to have a material impact on Park's consolidated statement of income.

ASU 2016-09 - Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting: In March 2016, FASB issued ASU 2016-09 - Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The ASU provides simplification for several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The new guidance was effective for annual reporting periods and interim reporting periods within those annual periods, beginning after December 15, 2016. Early adoption was permitted. The adoption of this guidance on January 1, 2017 did not have a material impact on Park's consolidated financial statements.

ASU 2016-13 - Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments: In June 2016, FASB issued ASU 2016-13 - Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The new guidance replaces the incurred loss model with an expected loss model, which is referred to as the current expected credit loss ("CECL") model. The CECL model is applicable to the measurement of credit losses on financial assets measured at amortized cost, including loan receivables, held-to-maturity debt securities, and reinsurance receivables. It also applies to off-balance sheet credit exposures not accounted for as insurance (loan commitments, standby letters of credit, financial guarantees, and other similar instruments) and net investments in leases recognized by a lessor. The CECL model requires an entity to estimate the credit losses over the life of an asset or off-balance sheet exposure. The new guidance is effective for annual reporting periods and interim reporting periods within those annual periods, beginning after December 15, 2019. Early adoption is permitted for annual reporting periods and interim reporting periods within those annual periods, beginning after December 15, 2018.

Management is currently evaluating the impact of the adoption of this guidance on Park's consolidated financial statements. We anticipate that the adoption of the CECL model will result in a material increase to Park's allowance for loan losses. Management has established a committee to oversee the implementation of CECL. This committee is currently assessing the data and system requirements necessary for adoption. Management plans to run our current incurred loss model and a CECL model concurrently for 12 months prior to the adoption of this guidance on January 1, 2020.

ASU 2016-15 - Statement of Cash Flows (Topic 203): Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force):  In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 203): Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force).  This ASU provides guidance on eight specific cash flow issues where current U.S. GAAP is either unclear or does not include specific guidance. The new guidance is effective for annual reporting periods, and interim reporting periods within those annual periods, beginning after December 15, 2017.  As such transactions arise, management will utilize the updated guidance within Park’s consolidated statements of cash flows. 

ASU 2017-04 - Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment:  In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This ASU eliminates Step 2 from the goodwill impairment test. Instead, under the new guidance, an entity is to perform its annual goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge would be recognized for the amount by which the carrying amount exceeds the reporting unit's fair value. The new guidance is effective for annual reporting periods, and interim reporting periods within those annual periods, beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of this guidance is not expected to have an impact on Park's consolidated financial statements.

ASU 2017-07 - Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost: In March 2017, the FASB issued ASU 2017-07 - Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This ASU requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component. The new guidance is effective for annual reporting periods, and interim reporting periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted for interim or annual periods. The adoption of this guidance is not expected to have a material impact on Park's consolidated financial statements.

ASU 2017-08 - Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities: In March 2017, the FASB issued ASU 2017-08 - Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. This ASU amends the amortization period for certain purchased callable debt securities held at a premium. It shortens the amortization period for the premium to the earliest call date. Under current U.S. GAAP, premiums on callable debt securities generally are amortized to the maturity date. The new guidance is effective for annual reporting periods, and interim reporting periods within those annual periods, beginning after December 15, 2018. Early adoption is permitted for interim or annual periods. The adoption of this guidance is not expected to have a material impact on Park's consolidated financial statements.

Management’s general practice is to proactively charge down loans individually evaluated for impairment to the fair value of the underlying collateral. At March 31, 2017 and December 31, 2016, there were $17.4 million and $24.7 million, respectively, of partial charge-offs on loans individually evaluated for impairment with no related allowance recorded and $6.3 million and $0.2 million, respectively, of partial charge-offs on loans individually evaluated for impairment that also had a specific reserve allocated.

 The allowance for loan losses included specific reserves related to loans individually evaluated for impairment at March 31, 2017 and December 31, 2016 of $1.1 million and $0.5 million, respectively. These loans with specific reserves had a recorded investment of $3.3 million and $2.1 million as of March 31, 2017 and December 31, 2016, respectively.

Interest income on nonaccrual loans individually evaluated for impairment is recognized on a cash basis only when Park expects to receive the entire recorded investment of the loan. Interest income on accruing TDRs individually evaluated for impairment continues to be recorded on an accrual basis. 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 months ended March 31, 2017 and March 31, 2016:

Credit Quality Indicators

Management utilizes past due information as a credit quality indicator across the loan portfolio. Past due information as of March 31, 2017 and December 31, 2016 is included in the tables above. The past due information is the primary credit quality indicator within the following classes of loans: (1) mortgage loans and installment loans in the construction real estate segment; (2) mortgage loans, HELOC and installment loans in the residential real estate segment; and (3) consumer loans. The primary credit indicator for commercial loans is based on an internal grading system that grades commercial loans on a scale from 1 to 8. Credit grades are continuously monitored by the responsible loan officer and adjustments are made when appropriate. A grade of 1 indicates little or no credit risk and a grade of 8 is considered a loss. Commercial loans that are pass-rated (graded an 1 through a 4) are considered to be of acceptable credit risk. Commercial loans graded a 5 (special mention) are considered to be watch list credits and a higher loan loss reserve percentage is allocated to these loans. Loans classified as special mention have potential weaknesses that require management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of Park’s credit position at some future date. Commercial loans graded 6 (substandard), also considered to be watch list credits, are considered to represent higher credit risk and, as a result, a higher loan loss reserve percentage is allocated to these loans. Loans classified as substandard are inadequately protected by the current sound worth and paying capacity of the obligor or the value of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that Park will sustain some loss if the deficiencies are not corrected. Commercial loans that are graded a 7 (doubtful) are shown as nonaccrual and Park generally charges these loans down to their fair value by taking a partial charge-off or recording a specific reserve. Loans classified as doubtful have all the weaknesses inherent in those classified as substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Certain 6-rated loans and all 7-rated loans are placed on nonaccrual status and included within the impaired category. A loan is deemed impaired when management determines the borrower's ability to perform in accordance with the contractual loan agreement is in doubt. Any commercial loan graded an 8 (loss) is completely charged off.

The tables below present the recorded investment by loan grade at March 31, 2017 and December 31, 2016 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 March 31, 2017 and March 31, 2016 did not meet the definition of a TDR as the modification was a delay in a payment that was considered to be insignificant. Management considers a forbearance period of up to three months or a delay in payment of up to 30 days to be insignificant. TDRs may be classified as accruing if the borrower has been current for a period of at least six months with respect to loan payments and management expects that the borrower will be able to continue to make payments in accordance with the terms of the restructured note. Management reviews all accruing TDRs quarterly to ensure payments continue to be made in accordance with the modified terms.

Quarterly, management reviews renewals/modifications of loans previously identified as TDRs to consider if it is appropriate to remove the TDR classification. If the borrower is no longer experiencing financial difficulty and the renewal/modification did not contain a concessionary interest rate or other concessionary terms, management considers the potential removal of the TDR classification. If deemed appropriate, the TDR classification is removed as the borrower has complied with the terms of the loan at the date of the renewal/modification and there was a reasonable expectation that the borrower would continue to comply with the terms of the loan subsequent to the date of the renewal/modification. The majority of these TDRs were originally considered restructurings in a prior year as a result of a renewal/modification with an interest rate that was not commensurate with the risk of the underlying loan at the time of the renewal/modification. There were no TDR classifications removed during the three-month period ended March 31, 2017. The TDR classification was removed on $806,000 of loans during the three-month period ended March 31, 2016, respectively.

At March 31, 2017 and December 31, 2016, there were $47.8 million and $46.9 million, respectively, of TDRs included in the nonaccrual loan totals. At March 31, 2017 and December 31, 2016, $40.2 million and $38.0 million, respectively, of these nonaccrual TDRs were performing in accordance with the terms of the restructured note. As of March 31, 2017 and December 31, 2016, loans with a recorded investment of $21.2 million and $18.2 million, respectively, were included in accruing TDR loan totals. Management will continue to review the restructured loans and may determine it appropriate to move certain nonaccrual TDRs to accrual status in the future.

At March 31, 2017 and December 31, 2016, Park had commitments to lend $1.1 million and $0.7 million, respectively, of additional funds to borrowers whose outstanding loan terms had been modified in a TDR.

There were $0.5 million and $0.2 million of specific reserves related to TDRs at March 31, 2017 and December 31, 2016, respectively. Modifications made in 2016 and 2017 were largely the result of renewals and extending the maturity date of the loan at terms consistent with the original note. These modifications were deemed to be TDRs primarily due to Park’s conclusion that the borrower would likely not have qualified for similar terms through another lender. Many of the modifications deemed to be TDRs were previously identified as impaired loans, and thus were also previously evaluated for impairment under Accounting Standards Codification (ASC) 310.  Additional specific reserves of $280,000 and $25,000 were recorded during the three-month periods ended March 31, 2017 and March 31, 2016, respectively, as a result of TDRs identified in the respective periods.

The terms of certain other loans were modified during the three-month periods ended March 31, 2017 and March 31, 2016 that did not meet the definition of a TDR. Modified substandard commercial loans which did not meet the definition of a TDR had a total recorded investment as of March 31, 2017 of $113,000. There were no modified substandard commercial loans which did not meet the definition of a TDR at March 31, 2016. 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 loan such that the modification was deemed to be at market terms.  Modified consumer loans which did not meet the definition of a TDR had a total recorded investment of $1.4 million and $2.0 million, as of March 31, 2017 and March 31, 2016, respectively. Many of these loans were to borrowers who were not experiencing financial difficulties but who were looking to reduce their cost of funds.

The following tables detail the number of contracts modified as TDRs during the three-month periods ended March 31, 2017 and March 31, 2016, as well as the recorded investment of these contracts at March 31, 2017 and March 31, 2016. The recorded investment pre- and post-modification is generally the same due to the fact that Park does not typically provide for forgiveness of principal.

Allowance For Loan Losses

Allowance for Loan Losses

The allowance for loan losses ("ALLL") is that amount management believes is adequate to absorb probable incurred credit losses in the loan portfolio based on management’s evaluation of various factors including overall growth in the loan portfolio, an analysis of individual loans, prior and current loss experience, and current economic conditions. A provision for loan losses is charged to operations based on management’s periodic evaluation of these and other pertinent factors as discussed within Note 1 of the Notes to Consolidated Financial Statements included in Park’s 2016 Annual Report.

Loss factors are reviewed quarterly and updated at least annually to reflect recent loan loss history and incorporate current risk and trends which may not be recognized in historical data. Several enhancements were made in the third quarter of 2016 as a result of management's quarterly review.

• Management updated the historical loss calculation during the third quarter of 2016, incorporating annualized net charge-offs plus changes in specific reserves through September 30, 2016. Additionally, management removed net charge-offs plus changes in specific reserves for the year ended December 31, 2009. Management's belief has been that historical losses should encompass the complete economic cycle. However, given the extended length of the recovery, management determined that 2009 data was no longer reflective of the current portfolio. Management has taken the look back period into consideration in the quarterly evaluation of environmental loss factors.

• As part of this mid-year historical loss update, management determined that it was no longer appropriate to more heavily weight those years with higher losses in the historical loss calculation and applied equal percentages to each of the years in this calculation. The trends that existed when management adopted this weighting no longer appear to exist, resulting in the adjustment back to equal weightings of all years evaluated.

• As part of the normal quarterly process, management reviewed and updated the environmental loss factors applied to the commercial portfolio in order to incorporate changes in the macroeconomic environment. Additionally, management updated the calculation of the loss emergence period utilizing a more granular process.

The impact of the changes described above resulted in a decrease of $3.8 million in the ALLL at September 30, 2016, compared to what the ALLL would have been had the calculation, and related assumptions, used at June 30, 2016 remained constant.

The historical loss factors were updated again in the fourth quarter of 2016 to incorporate losses through December 31, 2016. As part of the normal quarterly process, during the first quarter of 2017, management reviewed and updated the environmental loss factors applied to the commercial portfolio in order to incorporate changes in the macroeconomic environment.

The activity in the allowance for loan losses for the three months ended March 31, 2017 and March 31, 2016 is summarized below.

Loans collectively evaluated for impairment in the following tables include all performing loans at March 31, 2017 and December 31, 2016, 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 March 31, 2017 and December 31, 2016, 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 2016 Annual Report).

Management does not believe any of the unrecognized losses at March 31, 2017 or December 31, 2016 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 March 31, 2017, are shown in the following table by contractual maturity, except for asset-backed securities, which are shown as a single total, due to the unpredictability of the timing of principal repayments.

(1) The tax equivalent yield for obligations of state and political subdivisions includes the effects of a taxable equivalent adjustment using a 35% rate. The aggregate taxable equivalent adjustment was $786,000 for the three months ended March 31, 2017.

All of Park’s securities shown in the table above as obligations of U.S. Treasury and other U.S. Government sponsored entities' notes are callable notes. These callable notes have final maturities of 0.6 years to 3 years. Of the $268.4 million reported at March 31, 2017, none were expected to be called. The remaining average life of the entire investment portfolio is estimated to be 4.4 years.

There were no sales of investment securities during the three-month periods ended March 31, 2017 or 2016.

Investment securities having an amortized cost of $1,062 million and $937 million at March 31, 2017 and December 31, 2016, respectively, were pledged to collateralize government and trust department deposits in accordance with federal and state requirements, to secure repurchase agreements sold and as collateral for FHLB advance borrowings.

Share-Based Compensation

The Park National Corporation 2013 Long-Term Incentive Plan (the "2013 Incentive Plan") was adopted by the Board of Directors of Park on January 28, 2013 and was approved by Park's shareholders at the Annual Meeting of Shareholders on April 22, 2013. The 2013 Incentive Plan makes equity-based awards and cash-based awards available for grant to participants in the form of incentive stock options, nonqualified stock options, stock appreciation rights, restricted common shares, restricted stock unit awards that may be settled in common shares, cash or a combination of the two, unrestricted common shares and cash-based awards. Under the 2013 Incentive Plan, 600,000 common shares are authorized to be delivered in connection with grants under the 2013 Incentive Plan. The common shares to be delivered under the 2013 Incentive Plan may consist of either common shares currently held or common shares subsequently acquired by Park as treasury shares, including common shares purchased in the open market or in private transactions. No awards may be made under the 2013 Incentive Plan after April 22, 2023. At March 31, 2017, 429,889 common shares were available for future grants under the 2013 Incentive Plan.

During the three months ended March 31, 2017 and 2016, the Compensation Committee of the Board of Directors of Park granted awards of performance-based restricted stock units ("PBRSUs") covering an aggregate of 45,788 and 41,550 common shares, respectively, to certain employees of Park and its subsidiaries. The number of PBRSUs earned or settled will depend on the level of achievement with respect to certain performance criteria and are also subject to subsequent service-based vesting.

A summary of changes in the common shares subject to nonvested PBRSUs for the three months ended March 31, 2017 follows:

	Common shares subject to PBRSUs
Nonvested at January 1, 2017	85,425
Granted	45,788
Vested	9,674
Forfeited	150
Adjustment for performance conditions of PBRSUs (1)	(1,802	)
Nonvested at March 31, 2017	119,587

(1) The number of PBRSUs earned depends on the level of achievement with respect to certain performance criteria. Adjustment herein represents the difference between the maximum number of common shares which could be earned and the actual number earned for those PBRSUs as to which the performance period was completed.

On March 31, 2017, 9,674 PBRSUs granted in 2014 vested. A total of 3,293 common shares were withheld to pay employee income taxes. This resulted in a net amount of 6,381 common shares being issued to employees of Park.

Share-based compensation expense of $826,000 and $468,000 was recognized for the three-month periods ended March 31, 2017 and 2016, respectively.

Loan Servicing

Loan Servicing

Park serviced sold mortgage loans of $1.33 billion at each of March 31, 2017 and December 31, 2016 and $1.27 billion at March 31, 2016. At March 31, 2017, $3.6 million of the sold mortgage loans were sold with recourse, compared to $4.1 million at December 31, 2016 and $4.9 million at March 31, 2016. Management closely monitors the delinquency rates on the mortgage loans sold with recourse. At March 31, 2017 and December 31, 2016, management had established reserves of $287,000 and $266,000, respectively, to account for expected losses on loan repurchases.

When Park sells mortgage loans with servicing rights retained, servicing rights are initially recorded at fair value. Park selected the “amortization method” as permissible within U.S. GAAP, whereby the servicing rights capitalized are amortized in proportion to and over the period of estimated future servicing income of the underlying loan. At the end of each reporting period, the carrying value of mortgage servicing rights (“MSRs”) is assessed for impairment with a comparison to fair value. MSRs are carried at the lower of their amortized cost or fair value.

Activity for MSRs and the related valuation allowance follows:

Fair Value Disclosures [Abstract]

Fair Value

Fair Value

The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three levels of inputs that Park uses to measure fair value are as follows:

• Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that Park has the ability to access as of the measurement date.

• Level 2: Level 1 inputs for assets or liabilities that are not actively traded. Also consists of an observable market price for a similar asset or liability. This includes the use of “matrix pricing” to value debt securities absent the exclusive use of quoted prices.

• Level 3: Consists of unobservable inputs that are used to measure fair value when observable market inputs are not available. This could include the use of internally developed models, financial forecasting and similar inputs.

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability between market participants at the balance sheet date. When possible, the Company looks to active and observable markets to price identical assets or liabilities. When identical assets and liabilities are not traded in active markets, the Company looks to observable market data for similar assets and liabilities. However, certain assets and liabilities are not traded in observable markets and Park must use other valuation methods to develop a fair value. The fair value of impaired loans is typically based on the fair value of the underlying collateral, which is estimated through third-party appraisals in accordance with Park's valuation requirements under its commercial and real estate loan policies.

There were no transfers between Level 1 and Level 2 during the three months ended March 31, 2017 or 2016. Management’s policy is to transfer assets or liabilities from one level to another when the methodology to obtain the fair value changes such that there are more or fewer unobservable inputs as of the end of the reporting period.

The following methods and assumptions were used by the Company in determining the fair value of the financial assets and liabilities discussed above:

Investment securities: Fair values for investment securities are based on quoted market prices, where available. If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments. For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows.

Fair value swap: The fair value of the swap agreement entered into with the purchaser of the Visa Class B shares represents an internally developed estimate of the exposure based upon probability-weighted potential Visa litigation losses.

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

Mortgage loans held for sale: Mortgage loans held for sale are carried at their fair value. Mortgage loans held for sale are estimated using security prices for similar product types and, therefore, are classified in Level 2.

The tables below are a reconciliation of the beginning and ending balances of the Level 3 inputs for the three months ended March 31, 2017 and 2016, 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, real estate appraisals, income approach appraisals, and lot development loan appraisals, received by the Company. These are discussed below:

• Real estate appraisals typically incorporate measures such as recent sales prices for comparable properties. Appraisers may make adjustments to the sales prices of the comparable properties as deemed appropriate based on the age, condition or general characteristics of the subject property. Management generally applies a 15% discount to real estate appraised values which management expects will cover all disposition costs (including selling costs). This 15% discount is based on historical discounts to appraised values on sold OREO properties.

• Income approach appraisals typically incorporate the annual net operating income of the business divided by an appropriate capitalization rate, as determined by the appraiser. Management generally applies a 15% discount to income approach appraised values which management expects will cover all disposition costs (including selling costs).

• Lot development loan appraisals are typically performed using a discounted cash flow analysis. Appraisers determine an anticipated absorption period and a discount rate that takes into account an investor’s required rate of return based on recent comparable sales. Management generally applies a 6% discount to lot development appraised values, which is an additional discount above the net present value calculation included in the appraisal, to account for selling costs.

MSRs: MSRs are carried at the lower of cost or fair value. MSRs do not trade in active, open markets with readily observable prices. For example, sales of MSRs do occur, but precise terms and conditions typically are not readily available. As such, management, with the assistance of a third-party specialist, determines fair value based on the discounted value of the future cash flows estimated to be received. Significant inputs include the discount rate and assumed prepayment speeds. The calculated fair value is then compared to market values where possible to ascertain the reasonableness of the valuation in relation to current market expectations for similar products. Accordingly, MSRs are classified as Level 2.

The following tables present assets and liabilities measured at fair value on a nonrecurring basis. Collateral dependent impaired loans are carried at fair value if they have been charged down to fair value or if a specific valuation allowance has been established. A new cost basis is established at the time a property is initially recorded in OREO. OREO properties are carried at fair value if a devaluation has been taken to the property's value subsequent to the initial measurement.

The expense from credit adjustments related to impaired loans carried at fair value during the three months ended March 31, 2017 and 2016 was $0.3 million and $0.6 million, respectively.

MSRs totaled $9.3 million at March 31, 2017. Of this $9.3 million MSR carrying balance, $6.9 million was recorded at fair value and included a valuation allowance of $0.7 million. The remaining $2.4 million was recorded at cost, as the fair value of the MSRs exceeded cost at March 31, 2017. At December 31, 2016, MSRs totaled $9.3 million. Of this $9.3 million MSR carrying balance, $6.8 million was recorded at fair value and included a valuation allowance of $0.7 million. The remaining $2.5 million was recorded at cost, as the fair value exceeded cost at December 31, 2016. The income related to MSRs carried at fair value during the three months ended March 31, 2017 was $59,000. There was no income or expense related to MSRs carried at fair value during the three months ended March 31, 2016.

Total OREO held by Park at March 31, 2017 and December 31, 2016 was $13.7 million and $13.9 million, respectively. Approximately 50% of OREO held by Park at each of March 31, 2017 and December 31, 2016 was carried at fair value due to fair value adjustments made subsequent to the initial OREO measurement. At March 31, 2017 and December 31, 2016, OREO held at fair value, less estimated selling costs, amounted to $6.8 million and $6.9 million, respectively. The net expense related to OREO fair value adjustments was $73,000 and $118,000 for the three-month periods ended March 31, 2017 and 2016, respectively.

The following methods and assumptions were used by Park in estimating its fair value disclosures for assets and liabilities not discussed above:

Cash and cash equivalents:The carrying amounts reported in the consolidated condensed balancesheets for cash and short-term instruments approximate those assets’ fair values.

Other investments: FHLB and FRB stock within "Other investments" are carried at their respective redemption values as it is not practical to calculate their fair values. Additional investments within "Other investments" are carried at their cost basis as these investments do not have a readily determinable fair value and Park does not have the ability to influence the operating or financial decisions of the investee.

Loans receivable:For variable-rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values. The fair values for certain mortgage loans (e.g., one-to-four family residential) are based on quoted market prices of similar loans sold in conjunction with securitization transactions, adjusted for differences in loan characteristics. The fair values for other loans are estimated using discounted cash flow analyses, based upon interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. The methods utilized to estimate the fair value do not necessarily represent an exit price.

Off-balance sheet instruments:Fair values for Park’s loan commitments and standby letters of credit are based on the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing. The carrying amount and fair value are not material.

Deposit liabilities:The fair values disclosed for demand deposits (e.g., interest and non-interest checking, savings, and money market accounts) are, by definition, equal to the amounts payable on demand at the reporting date (i.e., their carrying amounts). The carrying amounts for variable-rate, fixed-term certificates of deposit approximate their fair values at the reporting date. Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities of time deposits.

Short-term borrowings:The carrying amounts of federal funds purchased, borrowings under repurchase agreements and other short-term borrowings approximate their fair values.

Long-term debt:Fair values for long-term debt are estimated using a discounted cash flow calculation that applies interest rates currently being offered on long-term debt to a schedule of monthly maturities.

Subordinated notes:Fair values for subordinated notes are estimated using a discounted cash flow calculation that applies interest rate spreads currently being offered on similar debt structures to a schedule of monthly maturities.

The fair value of financial instruments at March 31, 2017 and December 31, 2016, 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. Park's repurchase agreements with a third-party financial institution are classified as long-term debt on the consolidated condensed balance sheets.

All repurchase agreements are subject to terms and conditions of repurchase/security agreements between Park and the client and are accounted for as secured borrowings. Park's repurchase agreements reflected in short-term borrowings consisted of customer accounts and securities which are pledged on an individual security basis.

At March 31, 2017 and December 31, 2016, Park's repurchase agreement borrowings totaled $520 million and $510 million, respectively. At both March 31, 2017 and December 31, 2016, $300 million of Park's repurchase agreement borrowings were classified as long-term debt with the remaining amount being classified as short-term debt on the consolidated condensed balance sheets. These borrowings were collateralized with U.S. government and agency securities with a carrying value of $594 million and $569 million at March 31, 2017 and December 31, 2016, respectively. Declines in the value of the collateral would require Park to pledge additional securities. As of March 31, 2017 and December 31, 2016, Park had $570 million and $640 million, respectively, of available unpledged securities.

The table below shows the remaining contractual maturity of repurchase agreements by collateral pledged at March 31, 2017 and December 31, 2016:

	March 31, 2017
(in thousands)	Remaining Contractual Maturity of the Agreements

On November 30, 2012, Park restructured $300 million in repurchase agreements with a third-party financial institution and paid a $25 million prepayment penalty. The penalty is included in long-term debt and is being amortized as an adjustment to interest expense over the remaining term of the repurchase agreements using the effective interest method. Of the $25 million prepayment penalty, $3.5 million and $4.7 million remained unamortized as of March 31, 2017 and December 31, 2016, respectively.

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.
