PARK NATIONAL CORPORATION
NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
Note 1 – Basis of Presentation
The accompanying unaudited consolidated condensed financial statements included in this report have been prepared for Park National Corporation (sometimes also referred to as the “Registrant”) and its subsidiaries. Unless the context otherwise requires, references to "Park", the "Corporation" or the "Company" and similar terms mean Park National Corporation and its subsidiaries. In the opinion of management, all adjustments (consisting of normal recurring accruals) necessary for a fair presentation of the results of operations for the interim periods included herein have been made. The results of operations for the three-month and nine-month periods ended September 30, 2020 are not necessarily indicative of the operating results to be anticipated for the year ending December 31, 2020.
The accompanying unaudited consolidated condensed financial statements have been prepared in accordance with the instructions for Form 10-Q and, therefore, do not include all information and footnotes necessary for a fair presentation of the condensed balance sheets, condensed statements of income, condensed statements of comprehensive income, condensed statements of changes in shareholders’ equity and condensed statements of cash flows in conformity with U.S. GAAP. These financial statements should be read in conjunction with the consolidated financial statements included in Item 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA in the Annual Report on Form 10-K of Park for the fiscal year ended December 31, 2019 ("Park's 2019 Form 10-K"). Certain prior period amounts have been reclassified to conform to the current period presentation.
Park’s significant accounting policies are described in Note 1 Summary of Significant Accounting Policies of the Notes to Consolidated Financial Statements included in Park’s 2019 Form 10-K. 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.
The COVID-19 pandemic has caused significant, unprecedented disruption around the world that has affected daily living and negatively impacted the global economy. The effects of the COVID-19 pandemic may meaningfully impact significant estimates such as the allowance for loan losses, goodwill, mortgage servicing rights, and pension plan obligations and related expenses. Additionally, the pandemic may particularly impact certain loan concentrations in the hotel and accommodations, restaurant and food service, and strip shopping center industries.
Note 2 - Adoption of New Accounting Pronouncements and Issued But Not Yet Effective Accounting Standards
The following is a summary of new accounting pronouncements impacting Park's consolidated financial statements, and issued accounting standards not yet effective for Park:
Adoption of New Accounting Pronouncements
ASU 2018-13 - Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement: In August 2018, the FASB issued ASU 2018-13 - Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. This ASU modifies the disclosure requirements for fair value measurements in Topic 820, Fair Value Measurement by removing, modifying and adding certain requirements. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The adoption of this guidance on January 1, 2020 did not have an impact on Park’s consolidated financial statements, but did impact disclosures.
ASU 2020-04 - Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting: In March 2020, the FASB issued ASU 2020-04 - Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This ASU provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments in this ASU are effective from March 12, 2020 through December 31, 2022. The adoption of this guidance did not have a material impact on Park's consolidated financial statements, but Park will consider this guidance as contracts are transitioned from LIBOR to another reference rate.

Issued But Not Yet Effective Accounting Standards
ASU 2016-13 - Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments: In June 2016, the FASB issued ASU 2016-13 - Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The new accounting guidance in this ASU 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, HTM debt securities, and reinsurance receivables. It also applies to off-balance sheet credit exposures not accounted for as insurance (loan commitments, standby letters of credit, financial guarantees, and other similar instruments) and net investments in leases recognized by a lessor. The CECL model requires an entity to estimate credit losses over the life of an asset or off-balance sheet credit exposure. The new accounting guidance was to have been effective for Park for annual reporting periods and interim reporting periods within those annual periods, beginning after December 15, 2019.
Section 4014 of the CARES Act provides financial institutions with optional temporary relief from having to comply with ASU 2016-13 including the CECL methodology for estimating the allowance for credit losses. This temporary relief will expire on the earlier of the date on which the national emergency concerning the COVID-19 outbreak terminates or December 31, 2020, with adoption being effective retrospectively as of January 1, 2020.
Park elected to delay the implementation of CECL following the effectiveness of the CARES Act. The CECL standard requires
financial institutions to calculate an allowance utilizing a reasonable and supportable forecast period which Park has established
as a one-year period. Much is still unknown about the economic impact of COVID-19 including the duration of the pandemic,
future government programs that may be established as a result of the pandemic, and the resiliency of the U.S. economy,
making any forecast subject to large fluctuations in the coming months. In this unprecedented situation, Park believes that
adoption of the CECL model in the first quarter 2020 would have added an unnecessary level of subjectivity and volatility to
the calculation of the allowance for credit losses.
With the delay, management is currently evaluating the impact of adoption of this new accounting guidance on Park’s consolidated financial statements. Adoption will be applied through a one-time cumulative-effect adjustment to retained earnings as of January 1, 2020. Management has developed a quantitative credit model and is completing the process of validation. Management is still finalizing the analysis of qualitative factors, to capture inherent risks, which are not included within the quantitative credit model. Management, along with Park’s CECL Committee, is in the process of implementing the accounting, processes, controls and governance required to comply with the new accounting guidance.
The Company is using an economic forecast model to estimate expected credit losses over a one-year reasonable and supportable forecast period and then revert, over a one-year period, to longer term historical loss experience to arrive at lifetime expected credit losses. The estimated change in the allowance for credit losses as compared to Park's historical ALLL is primarily due to required increases for residential mortgage, home equity, and installment loans to address the requirement to estimate lifetime expected credit losses and the remaining length of time to maturity for these loans as well as an increase in reserves on acquired non-impaired loans which have low reserve levels under the incurred loss accounting guidance. Offsetting declines in the allowance are expected for commercial and commercial real estate loans due to their short-term nature. Additionally, management expects an increase in the allowance for credit losses for unfunded commitments.
While it is expected that the adoption of this ASU could increase the allowance for credit losses, many factors will determine the ultimate calculation at December 31, 2020. The adoption of this ASU will not, however, change the overall credit risk in the Company's loan, lease and investment securities portfolios or the ultimate losses therein. The transition adjustment to increase the allowance will primarily result in a decrease to shareholders' equity, net of income taxes. The ultimate impact of the adoption of this ASU will depend on the composition of the loan, lease and investment securities portfolios, finalization of credit loss models, and macroeconomic conditions and forecasts that exist at the adoption date.
ASU 2018-14 - Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans: In August 2018, the FASB issued ASU 2018-14 - Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans. The amendments in this ASU modify the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans by removing disclosures that are no longer considered cost beneficial, clarifying the specific requirements of disclosures and adding disclosure requirements identified as relevant. The amendments in this ASU are effective for fiscal years ending after December 15, 2020. Early adoption is permitted. The adoption of this guidance will not have an impact on Park’s consolidated financial statements, but will impact disclosures.

ASU 2018-19 - Codification Improvements to Topic 326, Financial Instruments - Credit Losses: In November 2018, the FASB issued ASU 2018-19 - Codification Improvements to Topic 326, Financial Instruments - Credit Losses. The amendment in this ASU clarifies that receivables arising from operating leases are not within the scope of Subtopic 326-20. Impairment of receivables arising from operating leases are to be accounted for in accordance with Topic 842, Leases. Park will consider this clarification in determining the appropriate adoption of ASU 2016-13.
ASU 2019-04 - Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments: In April 2019, the FASB issued ASU 2018-19 - Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments. This ASU includes amendments that clarify or address specific issues about certain aspects of the amendments in ASU 2016-01, Financial Instruments - Overall (Subtopic 925-10): Recognition and Measurement of Financial Assets and Financial Liabilities, ASU 2016-13 - Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, and ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities.
Park has already adopted ASU 2016-01. As a result, certain provisions in the amendments within ASU 2019-04 related to the same topics as ASU 2016-01 are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The adoption of the provisions related to the same topics as ASU 2016-01 on January 1, 2020 did not have a material effect on Park’s consolidated financial statements.
For the amendments related to Topic 326 that clarify or address specific aspects of ASU 2016-13, Park will consider these clarifications in determining the appropriate adoption of ASU 2016-13.
Park has already adopted ASU 2017-12. As a result, the amendments within ASU 2019-04 related to the same topics as ASU 2017-12 were effective as of January 1, 2020. This ASU allows entities, like Park, that did not reclassify debt securities from HTM to AFS upon the adoption of ASU 2017-12 to reclassify these securities as of the adoption of ASU 2019-04. Park considered this option and, effective September 1, 2019, reclassified all HTM debt securities to AFS. The transfer occurred at fair value and resulted in an unrealized gain, net of taxes, of $19.1 million being recorded in other comprehensive income.
ASU 2019-05 - Financial Instruments - Credit Losses (Topic 326): In May 2019, the FASB issued ASU 2019-05 - Financial Instruments - Credit Losses (Topic 326). The amendments in this ASU provide entities that have certain instruments within the scope of Subtopic 326-20, Financial Instruments - Credit Losses - Measured at Amortized Cost, with an option to irrevocably elect the fair value option in Subtopic 825-10, Financial Instruments - Overall, applied on an instrument-by-instrument basis for eligible instruments, upon adoption of Topic 326. Park will consider this amendment in determining the appropriate adoption of ASU 2016-13.
ASU 2019-11 - Codification Improvements to Topic 326, Financial Instruments - Credit Losses: In November 2019, the FASB issued ASU 2019-11 - Codification Improvements to Topic 326, Financial Instruments - Credit Losses. This ASU represents changes to clarify, correct errors in, or improve the ASC related to five topics. The amendments make the ASC easier to understand and easier to apply by eliminating inconsistencies and providing clarifications. Park will consider these clarifications and improvements in determining the appropriate adoption of ASU 2016-13.
ASU 2019-20 - Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes: In December 2019, the FASB issued ASU 2019-20 - Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This ASU includes amendments to simplify accounting for income taxes by removing certain exceptions and adding requirements with the intention of simplifying and clarifying existing guidance. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption is permitted. The adoption of this guidance will not have a material impact on Park's consolidated financial statements.
ASU 2020-01 - Investments - Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) - Clarifying the Interactions between Topic 321, Topic 323, and Topic 815: In January 2020, the FASB issued ASU 2020-01 - Investments - Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) - Clarifying the Interactions between Topic 321, Topic 323, and Topic 815. This ASU represents changes to clarify certain interactions between the guidance to account for certain equity securities under Topic 321, the guidance to account for investments under the equity method of accounting in Topic 323, and the guidance in Topic 815. These amendments improve current U.S. GAAP by reducing diversity in practice and increasing comparability of the accounting for these transactions. The amendments in this ASU are effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. Early adoption is permitted. The adoption of this guidance will not have a material impact on Park's consolidated financial statements.

Note 3 - Business Combinations
CAB Financial Corporation
On April 1, 2019, CAB Financial Corporation, a South Carolina corporation, merged with and into Park, with Park continuing as the surviving entity pursuant to the Agreement and Plan of Merger and Reorganization (the "CABF Merger Agreement"), dated as of September 12, 2018, by and between Park and CABF. Immediately following the CABF merger into Park, Carolina Alliance Bank, a South Carolina state-chartered bank and a wholly-owned subsidiary of CABF, was merged with and into PNB, with PNB as the surviving bank. In accordance with the transactions completed by the CABF Merger Agreement (the "Carolina Alliance acquisition"), CABF shareholders received for each share of their CABF common stock (i) $3.80 in cash (the cash consideration) and (ii) 0.1378 of a Park common share (the stock consideration). CABF stock options and restricted stock awards were fully vested (with any performance-based vesting condition deemed satisfied) and canceled and converted automatically into the right to receive merger consideration.
Purchase consideration consisted of 1,037,205 Park common shares, valued at $98.3 million, and $28.6 million in cash to acquire 100% of CABF's outstanding shares of common stock.
Carolina Alliance's results of operations were included in Park's results beginning April 1, 2019. For the three months ended September 30, 2020 and 2019, Park recorded merger-related expenses of $158,000 and $654,000, respectively, and for the nine months ended September 30, 2020 and 2019, Park recorded merger-related expenses of $602,000 and $6.9 million associated with the Carolina Alliance acquisition.
Goodwill of $46.9 million arising from the Carolina Alliance acquisition consisted largely of synergies and the cost savings resulting from the combining of the operations of PNB and Carolina Alliance. The goodwill is not deductible for income tax purposes as the transaction was accounted for as a tax-free exchange.

The following table summarizes the consideration paid in the Carolina Alliance acquisition and the amounts of the assets acquired and liabilities assumed at their fair value:

Other liabilities | 35,951 |
Total liabilities assumed | 668,600 |
Net identifiable assets | 80,049 |
Goodwill | $ | 46,856 |

Park accounted for the Carolina Alliance acquisition using the acquisition method of accounting and accordingly, assets acquired, liabilities assumed and consideration exchanged were recorded at estimated fair value on the acquisition date, in accordance with FASB ASC Topic 805, Business Combinations.
The fair value of net assets acquired includes fair value adjustments to loans that were not considered impaired as of the acquisition date. The fair value adjustments were determined using discounted contractual cash flows. However, Park believed that all contractual cash flows related to these loans would be collected. As such, these loans were not considered impaired at the acquisition date and were not subject to the guidance relating to purchased credit impaired loans which have shown evidence of credit deterioration since origination. Loans acquired that were not subject to these requirements included non-impaired loans with a fair value and gross contractual amounts receivable of $560.2 million and $572.6 million, respectively, on the date of acquisition.

Management does not believe any of the unrealized losses at September 30, 2020 or December 31, 2019 represented other-than-temporary impairment. The unrealized losses are primarily the result of interest rate changes. These conditions will not prohibit Park from receiving its contractual principal and interest payments on these debt securities. The fair value of these debt securities is expected to recover as payments are received on these debt securities and they approach maturity. Should the impairment of any of these debt securities become other-than-temporary, the cost basis of the investment will be reduced and the resulting loss attributable to credit will be recognized in net income in the period the other-than-temporary impairment is identified.
Park’s U.S. Government sponsored entities' asset-backed securities consist primarily of 15-year residential mortgage-backed securities and collateralized mortgage obligations.

Credit Quality Indicators
Management utilizes past due information as a credit quality indicator across the loan portfolio. Past due information at September 30, 2020 and December 31, 2019 is included in the previous tables. The past due information is the primary credit quality indicator within the following classes of loans: (1) mortgage loans and installment loans in the construction real estate segment; (2) mortgage loans, HELOC and installment loans in the residential real estate segment; and (3) consumer loans. The primary credit indicator for commercial loans is based on an internal grading system that grades all commercial loans on a scale from 1 to 8. Credit grades are continuously monitored by the responsible loan officer and adjustments are made when appropriate. A grade of 1 indicates little or no credit risk and a grade of 8 is considered a loss. Commercial loans that are pass-rated (graded 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. Loans classified as special mention have potential weaknesses that require management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of Park’s credit position at some future date. Commercial loans graded a 6 (substandard), also considered watch list credits, are considered to represent higher credit risk and, as a result, a higher 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 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.

Loans and Leases Acquired with Deteriorated Credit Quality
In conjunction with the NewDominion acquisition, Park acquired loans with a book value of $277.9 million as of the July 1, 2018 acquisition date. These loans were recorded at the initial fair value of $272.8 million. Loans acquired with deteriorated credit quality with a book value of $5.1 million were recorded at the initial fair value of $4.9 million. The carrying amount of loans acquired with deteriorated credit quality at September 30, 2020 and December 31, 2019 was $1.7 million and $3.0 million, respectively, while the outstanding customer balance was $1.8 million and $3.2 million, respectively. At September 30, 2020 and December 31, 2019, an allowance for loan losses of $2,000 and $101,000, respectively, had been recognized related to the acquired impaired loans.
In conjunction with the Carolina Alliance acquisition, Park acquired loans and leases with a book value of $589.7 million as of the April 1, 2019 acquisition date. These loans and leases were recorded at the initial fair value of $578.6 million. Loans and leases acquired with deteriorated credit quality with a book value of $19.9 million were recorded at the initial fair value of $18.4 million. The carrying amount of loans and leases acquired with deteriorated credit quality at September 30, 2020 and December 31, 2019 was $10.2 million and $11.3 million, respectively, while the outstanding customer balance was $12.5 million and $13.8 million, respectively. At September 30, 2020 and December 31, 2019, an allowance for loan losses of $101,000 and $167,000, respectively, had been recognized related to the acquired impaired loans and leases.
Troubled Debt Restructurings
Management typically classifies loans as TDRs when a borrower is experiencing financial difficulties and Park has granted a concession to the borrower as part of a modification or in the loan renewal process. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of the borrower's debt in the foreseeable future without the modification. This evaluation is performed in accordance with the Company’s internal underwriting policy. Management’s policy is to modify loans by extending the term or by granting a temporary or permanent contractual interest rate below the market rate, not by forgiving debt. A court's discharge of a borrower's debt in a Chapter 7 bankruptcy is considered a concession when the borrower does not reaffirm the discharged debt.
Additionally, Park is working with borrowers impacted by the COVID-19 pandemic and providing modifications to include either interest only deferral or principal and interest deferral, in each case, for initial periods up to 90 days. As necessary, Park is making available a second 90-day interest only deferral or principal and interest deferral bringing the total potential deferral period to six months. A majority of these modifications are excluded from TDR classification under Section 4013 of the CARES Act or under applicable interagency guidance of the federal banking regulators. In accordance with this guidance, such modified loans will be considered current and will continue to accrue interest during the deferral period.
Certain other loans which were modified during the three-month and nine-month periods ended September 30, 2020 and September 30, 2019 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.
At September 30, 2020 and December 31, 2019, there were $22.9 million and $34.3 million, respectively, of TDRs included in the nonaccrual loan totals. At September 30, 2020 and December 31, 2019, $12.5 million and $23.2 million, respectively, of these nonaccrual TDRs were performing in accordance with the terms of the restructured notes. At September 30, 2020 and December 31, 2019, loans with a recorded investment of $23.9 million and $21.3 million, respectively, were included in accruing TDR loan totals. Management will continue to review the restructured loans and may determine it is appropriate to move certain nonaccrual TDRs to accrual status in the future.
At September 30, 2020 and December 31, 2019, Park had commitments to lend $4.7 million and $7.9 million, respectively, of additional funds to borrowers whose outstanding loan terms had been modified in a TDR.
At September 30, 2020 and December 31, 2019, there were $2.0 million and $2.2 million, respectively, of specific reserves related to TDRs. Modifications made in 2020 and 2019 were largely the result of renewals and extending the maturity date of the loans at terms consistent with the original notes. These modifications were deemed to be TDRs primarily due to Park’s conclusion that the borrower would likely not have qualified for similar terms through another lender. Many of the modifications deemed to be TDRs were previously identified as impaired loans, and thus were also previously evaluated for impairment under ASC 310. There were no additional specific reserves recorded during either of the three-month or nine-month periods ended September 30, 2020 or 2019 as a result of TDRs identified in the period.
Quarterly, management reviews renewals/modifications of loans previously identified as TDRs to consider if it is appropriate to remove the TDR classification. If the borrower is no longer experiencing financial difficulty and the renewal/modification did not contain a concessionary interest rate or other concessionary terms and the terms of the renewal/modification are considered to be market terms based on the current risk characteristics of the borrower, management considers the potential removal of the TDR classification. If deemed appropriate, the TDR classification is removed if the borrower has complied with the terms of the loan at the date of the renewal/modification and there was a reasonable expectation that the borrower would continue to comply with the terms of the loan subsequent to the date of the renewal/modification. The majority of these TDRs were originally considered restructurings in a prior year as a result of a renewal/modification with an interest rate that was not commensurate with the risk of the underlying loan at the time of the renewal/modification. The TDR classification was removed on $709,000 and $1.6 million of loans during the three-month and nine-month periods ended September 30, 2020, respectively. The TDR classification was removed on $15,000 and $38,000 of loans during the three-month and nine-month periods ended September 30, 2019, respectively.
The terms of certain other loans were modified during the three-month and nine-month periods ended September 30, 2020 and September 30, 2019 that did not meet the definition of a TDR. Excluding COVID-19 related modifications, there were no substandard commercial loans modified during either the three-month period ended September 30, 2020 or the nine-month period ended September 30, 2020 which did not meet the definition of a TDR. There were $0.4 million and $0.6 million of substandard commercial loans modified during the three-month and nine-month periods ended September 30, 2019, respectively, which did not meet the definition of a TDR. Excluding COVID-19 related modifications, consumer loans modified during the three-month and nine-month periods ended September 30, 2020 which did not meet the definition of a TDR had a total recorded investment of $16.7 million and $58.2 million, respectively. Consumer loans modified during the three-month and nine-month periods ended September 30, 2019 which did not meet the definition of a TDR had a total recorded investment of $11.9 million and $21.4 million, respectively. Many of these loans were to borrowers who were not experiencing financial difficulties but who were looking to reduce their cost of funds.
During the nine months ended September 30, 2020, Park modified 4,810 consumer loans, with an aggregate balance of $111.0 million, and modified 1,386 commercial loans, with an aggregate balance of $583.7 million, in each case related to a hardship caused by the COVID-19 pandemic and responses thereto. Of the $111.0 million in consumer COVID-19 related modifications, $2.3 million were already classified as TDRs due to previous modifications and $818,000 were classified as TDRs due to the COVID-19 modification. Of the $583.7 million in commercial COVID-19 related modifications, $6.0 million were already classified as TDRs due to previous modifications and $112,000 were classified as TDRs due to the COVID-19 modification. The remaining loans met the exclusion criteria for TDR accounting either in Section 4013 of the CARES Act or in applicable interagency guidance.
The following tables detail the number of contracts modified as TDRs during the three-month periods ended September 30, 2020 and September 30, 2019, as well as the recorded investment of these contracts at September 30, 2020 and September 30,

Note 7 – Allowance for Loan Losses
The allowance for loan losses is that amount management believes is adequate to absorb probable incurred credit losses in the loan portfolio based on management’s evaluation of various factors including the 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 - Summary of Significant Accounting Policies of the Notes to the Consolidated Financial Statements included in Park's 2019 Form 10-K.
Loss factors are reviewed quarterly and updated at least annually to reflect recent loan loss history and incorporate current risks and trends which may not be recognized in historical data. Management updated the historical loss calculation during the fourth quarter of 2019, incorporating annualized net charge-offs plus changes in specific reserves through December 31, 2019. With the addition of 2019 historical losses, management extended the historical loss period to 120 months from 108 months. The 120-month historical loss period captures all annual periods subsequent to June 2009, the end of the most recent recession, thus encompassing the full economic cycle to date.
For all loan types, management considers the following factors in determining loan collectability and the appropriate level of the allowance:
•Changes in the nature and volume of the portfolio and in the terms of loans, including:
◦Trends (e.g., growth, reduction) in specific categories of the loan portfolio, as well as adjustments to the types of loans offered by PNB and GFSC.
◦Level of and trend in loan delinquencies, troubled loans, commercial watch list and impaired loans.
◦Level of and trend in new nonaccrual loans.
◦Level of and trend in loan charge-offs and recoveries.
•Changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, and recovery practices.
•Changes in national and local economic and business conditions and developments that affect the collectability of the portfolio.
•The effect of other external factors such as competition and legal and regulatory requirements on the level of estimated losses in Park's existing portfolio.
The following are factors management reviews specifically for commercial loans on a quarterly or annual basis.
•Loss Emergence Period Factor: At least annually, management calculates the loss emergence period for each commercial loan segment. The loss emergence period is calculated based upon the average period of time it takes from the probable occurrence of a loss event to the credit being moved to nonaccrual. If the loss emergence period for any commercial loan segment is greater than one year, management applies additional general reserves to all performing loans within that segment of the commercial loan portfolio. The calculation of the loss emergence period was last updated in the fourth quarter of 2019.
During the third quarter of 2020, Park made the decision to extend the loss emergence period on all commercial loan types by six months. Management believes that the start of the COVID-19 pandemic in March 2020 represents the loss event. Management continues to refine estimated losses as a result of this March 2020 loss event. Approximately six months following the start of the pandemic, Park has experienced very little, if any, increase in delinquencies and charge-offs. Management believes that this is due to the unprecedented level of economic stimulus and CARES Act accommodations provided by the U.S. government which has delayed loan defaults and losses.
•Loss Migration Factor: Park’s commercial loans are individually risk graded. If loan downgrades occur, the probability of default increases, and accordingly, management allocates a higher percentage reserve to those accruing commercial loans graded special mention and substandard. Annually, management calculates a loss migration factor for each commercial loan segment for special mention and substandard credits based on a review of losses over the period of time a loan takes to migrate from pass-rated to impaired. The loss migration factor was last updated in the fourth quarter of 2019.
•Environmental Loss Factor: Management has identified certain macroeconomic factors that trend in accordance with losses in Park’s commercial loan portfolio. Certain environmental loss factors have been determined to correlate with higher charge-offs while other adjustments are based on a subjective evaluation of other environmental loss factors.

Table of Contents
Environmental factors applicable to the commercial loan portfolio include: the Ohio unemployment rate, percent change in Ohio GDP, the consumer confidence index, the prevalence of fixed rate loans in the portfolio, and other environmental factors. In evaluating the ongoing relevance and amount of the other environmental factors, management considers: changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off and recovery practices, changes in national and local economic and business conditions, and developments that affect the collectability of the portfolio, and the effect of other external factors such as competition and legal and regulatory requirements on the level of estimated losses in Park's existing portfolio. All of these factors are evaluated in relation to the historical look back period. At September 30, 2020 and December 31, 2019, such subjective environmental loss factor inputs accounted for 39% and 42%, respectively, of the allowance for loan losses driven by environmental loss factors.
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. The environmental loss factors were updated in the first, second, and third quarters of 2020 to consider the economic impact of the COVID-19 pandemic. These factors were increased from 0.60% of applicable loans at December 31, 2019 to 0.675% of applicable loans at March 31, 2020, to 0.75% of applicable loans at June 30, 2020, and to 0.825% at September 30, 2020. The increase in the first and second quarters of 2020 was the result of upward adjustments to the factors for Ohio unemployment, percent change in Ohio GDP and consumer confidence. The increase in the third quarter of 2020 was due to the increased uncertainty in the overall economic environment, the unknown length and severity of the pandemic and the limitations in the incurred loss model to capture all probable incurred losses during such uncertain times. Management will continue to evaluate this estimate of incurred losses as new information becomes available.
In addition to the increases in the environmental loss factor, in the second quarter, Park added additional reserves for three industries at particularly high risk due to the pandemic: hotels and accommodations, restaurants and food service, and strip shopping centers. These industries have had high levels of deferrals and have been particularly impacted by shut downs of non-essential businesses, increased health department regulations, and changes in consumer behavior. Management expects that a high percentage of the 4-rated credits in these portfolios will eventually migrate to special mention, substandard, or impaired status. As a result, additional reserves totaling $3.9 million were added for these portfolios on top of that already calculated. This amount was calculated by applying the loss factor for special mention credits to all 4-rated loans in these portfolios. A breakout of the 4-rated balances and additional reserve related to these portfolios is detailed in the following table.

| September 30, 2020
(in thousands) | 4-Rated Balance |  | 4-Rated Balance - Originated |  | 4-Rated Balance - Purchased |  | Additional Reserve
Hotels and accommodations | $ | 86,041 |  |  | $ | 85,050 |  |  | $ | 991 |  |  | $ | 1,435 |
Restaurants and food service | 34,263 |  |  | 28,291 |  |  | 5,972 |  |  | 658 |
Strip shopping centers | 181,517 |  |  | 158,790 |  |  | 22,727 |  |  | 1,789 |
Total | $ | 301,821 |  |  | $ | 272,131 |  |  | $ | 29,690 |  |  | $ | 3,882 |

Additionally, management applied a 1% reserve to all hotels and accommodations loans in the general reserve population to account for increased valuation risk. At September 30, 2020, Park's originated hotels and accommodation loans had a balance of $178.8 million with an additional reserve related to valuation risks of $1.8 million.
For the consumer portfolio, a specific COVID-19 factor was added to each segment equal to 50% of the 120-month historical loss factor. This increase considers the payment deferrals being provided to consumer loan customers as well as the likely delays in delinquencies and charge-offs as a result.
Much is still unknown about the economic impact of COVID-19, including the duration of the pandemic, future government programs that may be established as a result of the pandemic, and the resiliency of the U.S. economy. Management will continue to evaluate this estimate of incurred losses as new information becomes available. Given uncertainty about the magnitude and length of the COVID-19 pandemic and related economic shutdown, additional loan loss provisions may be required that would adversely impact earnings in future periods.
As of September 30, 2020, Park had $542.8 million of PPP loans which are included in the commercial, financial and agricultural portfolio segment. These loans are guaranteed by the SBA and thus have not been reserved for using the same

methodology as the rest of Park’s loan portfolio. A 10 basis point reserve was calculated for these loans to reflect minimal credit risk.

Park evaluates goodwill for impairment during the second quarter of each year, with financial data as of March 31. Based on the analysis performed as of April 1, 2020, the Company determined that goodwill for Park's reporting unit, PNB, was not impaired. During each of the second and third quarters of 2020, management determined that the deterioration in general economic conditions as a result of the COVID-19 pandemic and responses thereto represented a triggering event prompting an evaluation of goodwill impairment. Based on the analysis performed during each of the second and third quarters of 2020, the Company determined that goodwill was not impaired. Management continues to monitor economic factors to evaluate goodwill impairment.

Note 11 – Foreclosed and Repossessed Assets
Park typically transfers a loan to OREO at the time that Park takes deed/title to the real estate property asset. The carrying amounts of foreclosed real estate properties held at September 30, 2020 and December 31, 2019 are listed below, as well as the recorded investment of loans secured by residential real estate properties for which formal foreclosure proceedings were in process at those dates.

In addition to real estate, Park may also repossess different types of collateral. As of September 30, 2020 and December 31, 2019, Park had $3.6 million and $4.2 million, respectively, in other repossessed assets which are included in "Other assets" on the Consolidated Condensed Balance Sheets. As of both dates presented, the other repossessed assets largely consisted of an aircraft acquired as part of a loan workout.
Note 12 – Loan Servicing
Park serviced sold mortgage loans of $1.79 billion at September 30, 2020, $1.45 billion at December 31, 2019 and $1.41 billion at September 30, 2019. At September 30, 2020, $2.0 million of the sold mortgage loans were sold with recourse, compared to $2.3 million at December 31, 2019 and $2.4 million at September 30, 2019. Management closely monitors the delinquency rates on the mortgage loans sold with recourse. At September 30, 2020 and December 31, 2019, management had established reserves of $44,000 and $25,000, respectively, to account for expected losses on loan repurchases.
When Park sells mortgage loans with servicing rights retained, these servicing rights are initially recorded at fair value. Park has selected the “amortization method” as permissible within U.S. GAAP, whereby the servicing rights capitalized are amortized in proportion to and over the period of estimated future servicing income with respect to the underlying loan. At the end of each reporting period, the carrying value of MSRs is assessed for impairment with a comparison to fair value. MSRs are carried at the lower of their amortized cost or fair value. The amortization of MSRs is included within "Other service income" in the Consolidated Condensed Statements of Income.
Activity for MSRs and the related valuation allowance follows:

Note 13 - Leases
Park is a lessee in several noncancellable operating lease arrangements, primarily for retail branches, administrative and warehouse buildings, ATMs, and certain office equipment within its Ohio, North Carolina, South Carolina, and Kentucky markets. Certain of these leases contain renewal options for periods ranging from one to five years. Park’s leases generally do not include termination options for either party to the lease or restrictive financial or other covenants. Payments due under the lease contracts include fixed payments plus, for many of Park’s real estate leases, variable payments such as Park's proportionate share of property taxes, insurance, and common area maintenance.
The Company adopted ASU 2016-02, Leases (ASC 842), using the modified retrospective method as of the date of adoption, January 1, 2019, as permitted by the amendments in ASU 2018-11. As a result, the Company was not required to adjust its comparative period financial information for effects of the adoption of the standard or make the new required lease disclosures for periods prior to the effective date. Upon adoption of this accounting guidance on January 1, 2019, Park recorded an initial ROU asset of $11.0 million, and a lease liability of $11.8 million, and reclassified an existing deferred rent liability of $0.6 million. The impact to the Company's retained earnings, net of the tax impact, was $143,000.

Management elected to adopt the package of transition practical expedients and, therefore, has not reassessed (1) whether existing or expired contracts contain a lease, (2) the lease classification for existing or expired leases or (3) the accounting for initial direct costs that were previously capitalized. The Company did not elect the practical expedient to use hindsight for leases existing at the adoption date. Park elected the practical expedient, by class of underlying asset, to not separate non-lease components from the associated lease components. Additionally, Park has elected not to recognize ROU assets and lease liabilities for short-term leases that have a lease term of 12 months or less. The Company recognizes the lease payments associated with its short-term leases as an expense on a cash basis.
Management determines if an arrangement is or contains a lease at contract inception. If an arrangement is determined to be or contain a lease, Park recognizes a ROU asset and a lease liability at the lease commencement date. Leases are classified as operating or finance leases at the lease commencement date. At September 30, 2020 and December 31, 2019, all of Park's leases were classified as operating leases.
Park’s lease liability is initially and subsequently measured at the present value of the unpaid lease payments at the lease commencement date. Key estimates and judgments related to the lease liability include how management determines (1) the discount rate it uses to discount the unpaid lease payments to present value, (2) the lease term, and (3) lease payments.
•ASC 842 requires a lessee to discount its unpaid lease payments using the interest rate implicit in the lease or, if that rate cannot be readily determined, its incremental borrowing rate. Generally, management cannot determine the interest rate implicit in the lease because it does not have access to the lessor’s estimated residual value or the amount of the lessor’s deferred initial direct costs. Therefore, Park utilizes its incremental borrowing rate as the discount rate for leases. Park’s incremental borrowing rate for a lease is the rate of interest it would have to pay on a collateralized basis to borrow an amount equal to the lease payments under similar terms. To manage its capital and liquidity needs, Park periodically obtains wholesale funding from the FHLB on an over-collateralized basis. The impact of utilizing an interest rate on an over-collateralized borrowing versus a fully collateralized borrowing is not material. Therefore, the FHLB yield curve was selected by management as a baseline to determine Park’s discount rates for leases.
•The lease term for all of the Company’s leases includes the noncancellable period of the lease plus any additional periods covered by either Park's option to extend (or not to terminate) the lease that the Company is reasonably certain to exercise, or an option to extend (or not to terminate) the lease controlled by the lessor. If a lease contract contains multiple renewal options, management generally models lease cash flows through the first renewal option period unless the contract contains economic incentives or other conditions that increase the likelihood that additional renewals are reasonably certain to be exercised.
•Lease payments included in the measurement of the lease liability are comprised of the following:
–Fixed payments, including in-substance fixed payments, owed over the lease term;
–For certain of Park's gross real estate leases, non-lease components such as real estate taxes, insurance, and common area maintenance; and
–Variable lease payments that depend on an index or rate, initially measured using the index or rate at the lease commencement date.
The ROU asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for lease payments made at or before the lease commencement date, plus any initial direct costs incurred less any lease incentives received. For operating leases, the ROU asset is subsequently measured throughout the lease term at the carrying amount of the lease liability, plus initial direct costs, plus (minus) any prepaid (accrued) lease payments, less the unamortized balance of lease incentives received. Lease expense for lease payments is recognized on a straight-line basis over the lease term.
Park's operating lease ROU asset and lease liability are presented in “Operating lease right-of-use asset" and "Operating lease liability," respectively, on Park's Consolidated Condensed Balance Sheets. The carrying amount of Park's ROU asset and lease liability at September 30, 2020 was $18.0 million and $19.1 million, respectively. At December 31, 2019, the carrying amounts of Park's ROU asset and lease liability was $13.7 million and $14.5 million, respectively. Park's operating lease expense is recorded in "Occupancy expense" on the Company's Consolidated Condensed Statements of Income.

Note 14 – Repurchase Agreement Borrowings
Securities sold under agreements to repurchase ("repurchase agreements") with customers represent funds deposited by customers, generally on an overnight basis, that are collateralized by investment securities owned by Park. Repurchase agreements with customers are included in "Short-term borrowings" on the Consolidated Condensed Balance Sheets.
All repurchase agreements are subject to terms and conditions of repurchase/security agreements between Park and the client and are accounted for as secured borrowings. Park's repurchase agreements consisted of customer accounts and securities which are pledged on an individual security basis.
At September 30, 2020 and December 31, 2019, Park's repurchase agreement borrowings totaled $295 million and $176 million, respectively. These borrowings were collateralized with U.S. government and agency securities with a fair value of $322 million and $200 million at September 30, 2020 and December 31, 2019, respectively. Declines in the value of the collateral would require Park to pledge additional securities.

Note 15 - Derivatives
Park uses certain derivative financial instruments (or "derivatives") to meet the needs of its clients while managing the interest rate risk associated with certain transactions. Park does not use derivatives for speculative purposes. A summary of derivative instruments utilized by Park follows.
Interest Rate Swaps
Park utilizes interest rate swap agreements as part of its asset liability management strategy to help manage its interest rate risk position and as a means to meet the financing, interest rate and other risk management needs of qualifying commercial banking customers. The notional amount of the interest rate swaps does not represent the amount exchanged by the parties. The amount exchanged is determined by reference to the notional amount and the other terms of the individual interest rate swap agreements.
Borrowing Derivatives: Interest rate swaps with notional amounts totaling $25.0 million at both September 30, 2020 and December 31, 2019 were designated as cash flow hedges of certain FHLB advances.
Loan Derivatives: In conjunction with the Carolina Alliance acquisition, Park acquired interest rate swaps related to certain commercial loans. These interest rate swaps were simultaneously hedged by offsetting interest rate swaps that Carolina Alliance executed with a third party, such that Carolina Alliance minimized its net interest rate risk exposure resulting from such transactions. These interest rate swaps had a notional amount totaling $33.8 million and $35.5 million at September 30, 2020 and December 31, 2019, respectively.
All of the Company's interest rate swaps were determined to be fully effective during the three-month and nine-month periods ended September 30, 2020 and September 30, 2019. As such, no amount of ineffectiveness has been included in net income. Therefore, the aggregate fair value of the swaps is recorded in other assets and other liabilities with changes in fair value recorded in other comprehensive income. The amount included in accumulated other comprehensive income would be reclassified to current earnings should the hedges no longer be considered effective. Park expects the hedges to remain fully effective during the remaining respective terms of the swaps.

Mortgage Banking Derivatives
Commitments to fund mortgage loans (interest rate locks) to be sold into the secondary market and forward commitments for the future delivery of these mortgage loans are accounted for as free standing derivatives. In order to hedge the change in interest rates resulting from its commitments to fund the loans, the Company enters into forward commitments for the future delivery of mortgage loans when interest rate locks are entered into. These mortgage banking derivatives are not designated in hedge relationships. The fair value of the interest rate lock is recorded at the time the commitment to fund the mortgage loan is executed and is adjusted for the expected exercise of the commitment before the loan is funded. Fair values of these mortgage banking derivatives are estimated based on changes in mortgage interest rates from the date the interest on the loan is locked. Changes in the fair values of these derivatives are included in "Other service income" in the Condensed Consolidated Statements of Income.
At September 30, 2020 and December 31, 2019, Park had $136.8 million and $15.9 million, respectively, of interest rate lock commitments. The fair value of these mortgage banking derivatives was reflected by a derivative asset of $2.9 million and $221,000 at September 30, 2020 and December 31, 2019, respectively.

Other Derivatives
In connection with the sale of Park’s Class B Visa shares during 2009, Park entered into a swap agreement with the purchaser of the shares. The swap agreement adjusts for dilution in the conversion ratio of Class B Visa shares resulting from certain Visa litigation. At September 30, 2020, the fair value of the swap liability of $226,000 was an estimate of the exposure based upon probability-weighted potential Visa litigation losses.

Note 19 - 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 made equity-based awards and cash-based awards available for grant to participants (who could have been employees or non-employee directors) in the form of incentive stock options, nonqualified stock options, SARs, restricted common shares (“Restricted Stock”), restricted stock unit awards that may be settled in common shares, cash or a combination of the two (“Restricted Stock Units”), unrestricted common shares (“Other Stock-Based Awards”) and cash-based awards. Under the 2013 Incentive Plan, 600,000 common shares were authorized to be delivered in connection with grants under the 2013 Incentive Plan. The common shares to be delivered under the 2013 Incentive Plan are to consist of either common shares currently held or common shares subsequently acquired by Park as treasury shares, including common shares purchased in the open market or in private transactions.

Note 21 – Fair Value
The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three levels of inputs that Park uses to measure fair value are as follows:
•Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that Park has the ability to access as of the measurement date.
•Level 2: Level 1 inputs for assets or liabilities that are not actively traded. Also consists of an observable market price for a similar asset or liability. This includes the use of “matrix pricing” to value debt securities absent the exclusive use of quoted prices.
•Level 3: Consists of unobservable inputs that are used to measure fair value when observable market inputs are not available. This could include the use of internally developed models, financial forecasting and similar inputs.
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the balance sheet date. When possible, the Company looks to active and observable markets to price identical assets or liabilities. When identical assets and liabilities are not traded in active markets, the Company looks to observable market data for similar assets and liabilities. However, certain assets and liabilities are not traded in observable markets and Park must use other valuation methods to develop a fair value. The fair value of impaired loans is typically based on the fair value of the underlying collateral, which is estimated through third-party appraisals in accordance with Park's valuation requirements under its commercial and real estate loan policies.

The following methods and assumptions were used by the Company in determining the fair value of the financial assets and liabilities discussed above:
Interest rate swaps: The fair values of interest rate swaps are based on valuation models using observable market data as of the measurement date (Level 2).
Investment securities: Fair values for investment securities are based on quoted market prices, where available (Level 1). If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments (Level 2). For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows (Level 3).

Table of Contents
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: Mortgage IRLCs are based on current secondary market pricing and are classified as Level 2.
Mortgage loans held for sale: Mortgage loans held for sale are carried at their fair value. Mortgage loans held for sale are estimated using market prices for similar product types and, therefore, are classified in Level 2.

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 the client’s business, resulting in a
54

Table of Contents
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.
OREO: Assets acquired through or in lieu of loan foreclosure are initially recorded at fair value less costs to sell when acquired. The carrying value of OREO is not re-measured to fair value on a recurring basis, but is subject to fair value adjustments when the carrying value exceeds the fair value, less estimated selling costs. Fair value is based on recent real estate appraisals and is updated at least annually. These appraisals may utilize a single valuation approach or a combination of approaches including the comparable sales approach and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments result in a Level 3 classification of the inputs for determining fair value.
Appraisals for both collateral dependent impaired loans and OREO are performed by licensed appraisers. Appraisals are generally obtained to support the fair value of collateral. In general, there are three types of appraisals received by the Company: real estate appraisals, income approach appraisals, and lot development loan appraisals. These are discussed below:
•Real estate appraisals typically incorporate measures such as recent sales prices for comparable properties. Appraisers may make adjustments to the sales prices of the comparable properties as deemed appropriate based on the age, condition or general characteristics of the subject property. Management generally applies a 15% discount to real estate appraised values which management expects will cover all disposition costs (including selling costs). This 15% discount is based on historical discounts to appraised values on sold OREO properties.
•Income approach appraisals typically incorporate the annual net operating income of the business divided by an appropriate capitalization rate, as determined by the appraiser. Management generally applies a 15% discount to income approach appraised values which management expects will cover all disposition costs (including selling costs).
•Lot development loan appraisals are typically performed using a discounted cash flow analysis. Appraisers determine an anticipated absorption period and a discount rate that takes into account an investor’s required rate of return based on recent comparable sales. Management generally applies a 6% discount to lot development appraised values, which is an additional discount above the net present value calculation included in the appraisal, to account for selling costs.
Other repossessed assets: Other repossessed assets are initially recorded at fair value less costs to sell when acquired. The carrying value of other repossessed assets is not re-measured to fair value on a recurring basis, but is subject to fair value adjustments when the carrying value exceeds the fair value, less estimated selling costs. As of September 30, 2020 and December 31, 2019, other repossessed assets primarily consisted of aircraft acquired as part of a loan workout. Fair value is based on Aircraft Bluebook and VREF Aircraft Value Reference values based on the model of aircraft and adjustments for flight hours, features and other variables. Such adjustments result in a Level 3 classification of the inputs for determining fair value.
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.
55

Table of Contents
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. As of September 30, 2020, there were no PCI loans carried at fair value. A new cost basis is established at the time a property is initially recorded in OREO. OREO properties are carried at fair value if a devaluation has been taken with respect to the property's value subsequent to the initial measurement.

(1) Of the $11.1 million of aggregate revenue included within "Other service income", approximately $4.0 million is within the scope of ASC 606, with the remaining $7.1 million consisting primarily of residential real estate loan fees which are out of scope.
(2) Not within the scope of ASC 606.
(3) "Miscellaneous" income includes brokerage income, safe deposit box rentals, and miscellaneous bank fees totaling $5.4 million, all of which are within scope of ASC 606.
A description of Park's revenue streams accounted for under ASC 606 follows:
Income from fiduciary activities (gross): Park earns fiduciary fee income and investment brokerage fees from its contracts with trust customers for various fiduciary and investment-related services. These fees are earned over time as the Company provides the contracted monthly and quarterly services and are generally assessed based on the market value of the trust assets.
Service charges on deposit accounts and ATM fees: The Corporation earns fees from its deposit customers for transaction-based, account maintenance, and overdraft services. Transaction-based fees, which include services such as ATM use fees, stop payment charges, statement rendering, and ACH fees, are recognized at the time the transaction is executed as that is the point in time the Corporation fulfills the customer's request. Account maintenance fees, which relate primarily to monthly maintenance, are generally recognized at the end of the month, representing the period over which the Corporation satisfies the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are withdrawn from the customer's account balance.
Other service income: Other service income includes income from (1) the sale and servicing of loans sold to the secondary market, (2) incentive income from third-party credit card issuers, and (3) loan customers for various loan-related activities and services. Income related to the sale and servicing of loans sold to the secondary market is included within Other service income, but is not within the scope of ASC 606.

Debit card fee income: Park earns interchange fees from debit cardholder transactions conducted primarily through the Visa payment network. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, net of card network fees, concurrently with the transaction processing services provided to the cardholder.
Gain or loss on sale of OREO, net: The Corporation records a gain or loss from the sale of OREO when control of the property transfers to the buyer, which generally occurs at the time of delivery of an executed deed. When Park finances the sale of OREO to the buyer, the Corporation assesses whether the buyer is committed to perform the buyer's obligation under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the OREO asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on the sale, the Corporation adjusts the transaction price and related gain (loss) on sale if a significant financing component is present.
Note 23 - Subordinated Debt
On August 20, 2020, Park completed the issuance and sale of $175.0 million aggregate principal amount of its 4.50% Fixed-to-Floating Rate Subordinated Notes due 2030. The Subordinated Debt initially bears a fixed interest rate of 4.50% per year, payable semi-annually in arrears on March 1 and September 1 of each year, commencing on March 1, 2021. Commencing on September 1, 2025, the Notes will bear interest at a floating rate per annum equal to the Benchmark rate, which is expected to be Three-Month Term SOFR, plus a spread of 439 basis points for each quarterly interest period during the floating rate period, payable quarterly in arrears; provided, however, that if the Benchmark rate is less than zero, then the Benchmark rate shall be deemed to be zero. The Company may, at its option, beginning with the interest payment date of September 1, 2025 and on any interest payment date thereafter, redeem the Notes, in whole or in part, from time to time, subject to obtaining the prior approval of the holders of the Company’s senior indebtedness and of the Board of Governors of the Federal Reserve System to the extent the approval of the Federal Reserve is then required under the capital adequacy rules of the Federal Reserve, at a redemption price equal to 100% of the principal amount of the Notes being redeemed, plus accrued and unpaid interest thereon to but excluding the date of redemption. The issuance costs of the Subordinated Debt totaled $2.4 million, which is being amortized through the Subordinated Debt call date. The Subordinated Debt, net of unamortized issuance costs, totaled $172.7 million at September 30, 2020, and qualifies as Tier 2 capital for Park under the guidelines by the Federal Reserve Bank.

Non-GAAP Financial Measures
Item 2 of Part I of of this Quarterly Report on Form 10-Q contains non-U.S. GAAP financial measures where management believes it to be helpful in understanding Park’s results of operations or financial position. Where non-U.S. GAAP financial measures are used, the comparable U.S. GAAP financial measure, as well as the reconciliation to the comparable U.S. GAAP financial measure, can be found herein.
Items Impacting Comparability of Period Results
From time to time, revenue, expenses, and/or taxes are impacted by items judged by management of Park to be outside of ordinary banking activities and/or by items that, while they may be associated with ordinary banking activities, are so unusually large that their outsized impact is believed by management of Park at that time to be infrequent or short-term in nature. Most often, these items impacting comparability of period results are due to merger and acquisition activities and revenue and expenses related to former Vision Bank loan relationships. In other cases, they may result from management's decisions associated with significant corporate actions outside of the ordinary course of business.
Even though certain revenue and expense items are naturally subject to more volatility than others due to changes in market and economic environment conditions, as a general rule volatility alone does not result in the inclusion of an item as one impacting comparability of period results. For example, changes in the provision for loan losses (aside from former Vision Bank loan relationships), gains (losses) on equity securities, and asset valuation writedowns, reflect ordinary banking activities and are, therefore, typically excluded from consideration as items impacting comparability of period results.
Management believes the disclosure of items impacting comparability of period results provides a better understanding of our performance and trends and allows management to ascertain which of such items, if any, to include or exclude from an analysis of our performance; i.e., within the context of determining how that performance differed from expectations, as well as how, if at all, to adjust estimates of future performance taking such items into account.
Items impacting comparability of the results of particular periods are not intended to be a complete list of items that may materially impact current or future period performance.
FTE (fully taxable equivalent) Ratios
Interest income, yields, and ratios on a FTE basis are considered non-U.S. GAAP financial measures. Management believes net interest income on a FTE basis provides an insightful picture of the interest margin for comparison purposes. The FTE basis also allows management to assess the comparability of revenue arising from both taxable and tax-exempt sources. The FTE basis assumes a federal statutory corporate income tax rate of 21 percent. In the tables included within the "Net Interest Income" section of this MD&A, Park has provided detail of FTE interest income solely for the purpose of complying with SEC Regulation G and not as an indication that FTE interest income, yields and ratios are substitutes for interest income, yields and ratios, as determined in accordance with U.S. GAAP.
Paycheck Protection Program ("PPP") Loans
Park originated $543.1 million in loans as part of the PPP. These loans are not typical of Park's loan portfolio in that they are part of a specific government program to support businesses during the COVID-19 pandemic and are 100% guaranteed by the Small Business Administration ("SBA"). As such, management considers growth in the loan portfolio excluding PPP loans, the total allowance for loan losses on originated loans to total originated loans ratio (excluding PPP loans), and general reserve as a % of total originated loans (excluding acquisitions) less impaired commercial loans (excluding PPP loans) in addition to the related U.S. GAAP metrics which are not adjusted for PPP loans.
Critical Accounting Policies
Note 1 of the Notes to Consolidated Financial Statements included in Park’s 2019 Form 10-K 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.
The COVID-19 pandemic has caused significant, unprecedented disruption around the world that has affected daily living and negatively impacted the global economy. The effects of COVID-19 pandemic may meaningfully impact significant estimates such as the allowance for loan losses, goodwill, mortgage servicing rights, and pension plan obligations and related expenses.
68

Table of Contents
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 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 Loan Losses” section within this MD&A for additional discussion.
OREO, property acquired through foreclosure, is recorded at estimated fair value less anticipated selling costs (net realizable value). If the net realizable value is below the carrying value of the loan on the date of transfer, the difference is charged to the allowance for loan losses. Subsequent declines in value, OREO devaluations, are reported as adjustments to the carrying amount of OREO and are expensed within other income. Gains or losses not previously recognized, resulting from the sale of OREO, are recognized within other income on the date of sale.
U.S. GAAP requires management to establish a fair value hierarchy, which has the objective of maximizing the use of observable market inputs. U.S. GAAP also requires enhanced disclosures regarding the inputs used to calculate fair value. These are classified as Level 1, Level 2, and Level 3. Level 3 inputs are those with significant unobservable inputs that reflect a company’s own assumptions about the market for a particular instrument. Some of these inputs could be based on internal models and cash flow analyses. The large majority of Park’s assets whose fair value is determined using Level 2 inputs consists of AFS debt securities. The fair value of these AFS debt securities is calculated 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 debt securities but rather relying on the debt securities’ relationship to other benchmark quoted debt securities. Please see Note 21 - 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 each business acquired. Park’s goodwill, as of September 30, 2020, relates to the value inherent in the banking industry and that value is dependent upon the ability of Park’s national bank subsidiary, 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 evaluates goodwill for impairment during the second quarter of each year, with financial data as of March 31. Based on the analysis performed as of April 1, 2020, the Company determined that goodwill for Park's reporting unit, PNB, was not impaired. During each of the second and third quarters of 2020, management determined that the deterioration in general economic conditions as a result of the COVID-19 pandemic and responses thereto represented a triggering event prompting an evaluation of goodwill impairment. Based on the analysis performed during each of the second and third quarters of 2020, the Company determined that goodwill was not impaired. Management continues to monitor economic factors to evaluate goodwill impairment. 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 will 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.
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 pension plan; and
•the rate of salary increases where benefits are based on earnings.

Table of Contents
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.

COVID-19 Considerations
Banking has been identified by federal and state governmental authorities to be an essential service and Park is fully committed to continue serving our customers and communities through the COVID-19 public health crisis. For those in our communities experiencing a financial hardship, Park has offered various methods of support including loan modifications, payment deferral programs, participation in the CARES Act Paycheck Protection Program ("PPP") and various other case by case accommodations. Park has implemented various physical distancing guidelines to help protect associates, such as allowing associates to work from home, where practical, while maintaining customer service via our online banking services, mobile app, and ATMs, by keeping drive-thru lanes open to serve customers, maintaining selective branch office openings, and offering other banking services by appointment when necessary.
During the first nine months of 2020, Park provided calamity pay and special one-time bonuses to certain associates. The cost of the calamity pay and special bonuses amounted to $0.8 million and $2.9 million for the three-month and nine-month periods ended September 30, 2020, respectively, and is included within salaries expense.
Paycheck Protection Program: Through September 30, 2020, Park had approved and funded 4,439 loans totaling $543.1 million under the PPP. These PPP loans had an average principal balance of $122,000. Of the $543.1 million in PPP loans, 21 loans totaling $68.2 million had a principal balance that was greater than $2 million. For its assistance in making and retaining these loans, Park has received an aggregate of $20.2 million in fees from the SBA, of which $6.6 million were recognized during the nine months ended September 30, 2020. Park funded the PPP loans with excess on-balance sheet liquidity.
As of November 3, 2020, Park has submitted approximately 1,072 repayment requests on behalf of borrowers under the PPP to the SBA and has received $51.1 million in payments from the SBA.
Loan Modifications: During the nine months ended September 30, 2020, Park had modified 4,810 consumer loans, with an aggregate balance of $111 million, and modified 1,386 commercial loans, with an aggregate balance of $584 million, in each case related to a hardship caused by the COVID-19 pandemic and responses thereto. Park is working with borrowers and providing modifications in the form of either interest only deferral or principal and interest deferral, in each case, for initial periods of up to 90 days. As necessary, Park is making available a second 90 day interest only deferral or principal and interest deferral bringing the total potential deferral period to six months. Modifications are structured in a manner to best address each individual customer's current situation. A majority of these modifications are excluded from TDR classification under Section 4013 of the CARES Act or under applicable interagency guidance of the federal banking regulators. Modified loans will be

Commercial loans are graded from 1 to 8. 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) have potential weaknesses that require management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of Park’s credit position at some future date. Commercial loans graded a 6 (substandard) are inadequately protected by the current sound worth and paying capacity of the obligor or the value of the collateral pledged, if any. Commercial loans that are graded a 7 (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. Any commercial loan graded an 8 (loss) is completely charged-off.
Park considers a loan out of deferral when the first regular payment is due and that payment is subsequently made. The table below details the status of loans with COVID-19 deferrals at September 30, 2020.

The increase was a result of a $23.9 million decrease in interest expense, partially offset by a $2.4 million decrease in interest income.
The $2.4 million decrease in interest income was primarily due to a $7.6 million decrease in investment income, partially offset by a $5.2 million increase in interest income on loans.The decrease in investment income was partially the result of a $190.2 million decrease in average investments from $1.38 billion for the nine months ended September 30, 2019 to $1.19 billion for the nine months ended September 30, 2020. The decrease in investment income was also the result of a decrease in the yield on investments, which decreased 16 basis points to 2.62% for the nine months ended September 30, 2020, compared to 2.78% for the nine months ended September 30, 2019. The increase in interest income on loans was partially the result of a $774.0 million increase in average loans from $6.11 billion for the nine months ended September 30, 2019, to $6.89 billion for the nine months ended September 30, 2020. The increase in average loans was partially offset by the decrease in the yield on loans, which decreased 49 basis points to 4.66% for the nine months ended September 30, 2020, compared to 5.15% for the nine months

ended September 30, 2019. Interest income was impacted by the acquisition of CAB Financial Corporation, the parent of Carolina Alliance on April 1, 2019. The Carolina Alliance Bank Division contributed an aggregate of $22.7 million to interest income at PNB during the nine months ended September 30, 2020, compared to $16.9 million for the nine months ended September 30, 2019.
The $23.9 million decrease in interest expense was primarily due to an $19.4 million decrease in interest expense on deposits as well as a $4.5 million decrease in interest expense on borrowings. The decrease in interest expense on deposits was the result of a decrease in the cost of deposits of 56 basis points from 1.03% for the nine months ended September 30, 2019 to 0.47% for the nine months ended September 30, 2020. This was partially offset by a $383.5 million increase in average interest-bearing deposits from $4.96 billion for the nine months ended September 30, 2019, to $5.35 billion for the nine months ended September 30, 2020. Interest expense was impacted by the acquisition of Carolina Alliance. The Carolina Alliance Bank Division contributed an aggregate of $2.6 million to interest expense at PNB during both the nine months ended September 30, 2020 and 2019. The decrease in interest expense on borrowings was partially the result of a $180.1 million decrease in average borrowings from $580.3 million for the nine months ended September 30, 2019, to $400.1 million for the nine months ended September 30, 2020. The cost of borrowings also decreased by 57 basis points, from 2.10% for the nine months ended September 30, 2019 to 1.53% for the nine months ended September 30, 2020.
The provision for loan losses of $32.3 million for the nine months ended September 30, 2020 represented an increase of $25.7 million, compared to $6.6 million for the nine months ended September 30, 2019. Refer to the “Credit Metrics and Provision for Loan Losses” section for additional details regarding the level of the provision for loan losses recognized in each period presented above.

The $21.7 million increase was primarily related to a $14.4 million increase in other service income, which was primarily due to an increase in fee income from mortgage loan originations and investor rate locks; a $3.7 million increase in gain on sale of debt securities; a $2.4 million increase in other components of net periodic benefit income; a $1.5 million increase in debit card fee income; a $927,000 increase in gain (loss) on sale of OREO, net; a $741,000 increase in income from fiduciary activities; and a $376,000 increase in miscellaneous income, primarily related to an increase in operating lease income. These increases were partially offset by a $1.8 million decrease in service charges on deposits and a $728,000 decrease in gains (losses) from capital investments.

Credit Metrics and Provision for Loan Losses
The provision for loan losses is the amount added to the allowance for loan and lease losses to ensure the allowance is sufficient to absorb probable, incurred loan losses. The amount of the provision for 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.
The table below provides additional information on the provision for loan losses for the three-month and nine-month periods ended September 30, 2020 and 2019.

Net charge-offs as a % of average loans (annualized) | 0.02 | % | 0.01 | % | 0.02 | % | 0.04 | %

Loans acquired as part of the acquisitions of NewDominion and Carolina Alliance were recorded at fair value on the date of acquisition. An allowance is only established on these loans as a result of credit deterioration post acquisition.
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.

(1) Excludes PCI loans which are individually evaluated for impairment due to additional credit deterioration post acquisition. These loans had a balance of $0, $5,000 and $11,000 at September 30, 2020, December 31, 2019 and September 30, 2019, respectively.
(2) Excludes $542.8 million of PPP loans and $543,000 in related allowance at September 30, 2020. No PPP loans were outstanding at December 31, 2019 or September 30, 2019.
The allowance for loan losses of $87.0 million at September 30, 2020 represented a $30.4 million, or 53.6%, increase compared to $56.7 million at December 31, 2019. This increase was largely the result of a $26.7 million increase in general reserves on originated total loans and a $3.4 million increase in specific reserves. As of September 30, 2020, a $371,000 allowance had been established for performing acquired loans and a $103,000 allowance had been established for PCI loans. In addition to the established allowance related to acquired loans, as of September 30, 2020, these loans have a remaining purchase accounting discount of $8.1 million. The $26.7 million increase in general reserves was the result of the estimated increase in incurred losses as a result of the impact of the COVID-19 pandemic. This estimate was established based on consideration of Park's existing environmental loss factors, modification programs Park has put in place, and balances of high risk portfolios such as hotels and accommodations, restaurants and food service and strip shopping centers. Much is still unknown about the long-term economic impact of the COVID-19 pandemic and management will continue to evaluate this estimate of incurred losses as new information becomes available. See the section entitled "Allowance for loan losses" for further details.
Generally, management obtains updated valuations for all nonperforming loans at least annually. As new valuation information is received, management performs an evaluation and applies a discount for anticipated disposition costs to determine the net realizable value of the collateral, which is compared against the outstanding principal balance to determine if additional write-downs are necessary.
Nonperforming Assets: Nonperforming assets include: (1) loans whose interest is accounted for on a nonaccrual basis; (2) TDRs on accrual status; (3) loans which are contractually past due 90 days or more as to principal or interest payments but whose interest continues to accrue; (4) OREO which results from taking possession of property that served as collateral for a defaulted loan; and (5) other nonperforming assets. At September 30, 2020, December 31, 2019 and September 30, 2019, other nonperforming assets consisted of aircraft acquired as part of a loan workout.

Park classifies loans as nonaccrual when a loan (1) is maintained on a cash basis because of deterioration in the financial condition of the borrower, (2) payment in full of principal or interest is not expected, or (3) principal or interest has been in default for a period of 90 day for commercial loans and 120 days for all other loans. As a result, loans may be classified as nonaccrual despite being current with their contractual terms. The following table details the delinquency status of nonaccrual loans at September 30, 2020, December 31, 2019 and September 30, 2019. Loans are classified as current if they are less than 30 days past due.

Credit Quality Indicators: When determining the quarterly loan loss provision, Park reviews the grades of commercial loans. These loans are graded from 1 to 8. A grade of 1 indicates little or no credit risk and a grade of 8 is considered a loss. Commercial loans that are pass-rated (graded an 1 through a 4) are considered to be of acceptable credit risk. Commercial loans graded a 5 (special mention) are considered to be watch list credits and a higher loan loss reserve percentage is allocated to these loans. Commercial loans graded a 6 (substandard), also considered to be watch list credits, represent higher credit risk than those rated special mention and, as a result, a higher loan loss reserve percentage is allocated to these loans. Commercial loans that are graded a 7 (doubtful) are shown as nonperforming and Park charges these loans down to their fair value by taking a partial charge-off or recording a specific reserve. Any commercial loan graded an 8 (loss) is completely charged-off.

* Commercial loans include (1) Commercial, financial and agricultural loans, (2) Commercial real estate loans, (3) Commercial related loans in the construction real estate portfolio, (4) Commercial related loans in the residential real estate portfolio and (5) Leases.
At September 30, 2020, Park had $104.7 million of non-impaired commercial loans included on the watch list, compared to $28.3 million at December 31, 2019 and compared to $44.8 million at September 30, 2019. The existing conditions of these loans do not warrant classification as nonaccrual. However, these loans have shown some weakness and management performs additional analysis regarding each borrower's ability to comply with payment terms. The $76.4 million increase in non-impaired commercial watch list loans from December 31, 2019 to September 30, 2020 was largely due to $72.4 million of hotels and accommodation loans that were downgraded to special mention or substandard as a result of the impact of COVID-19. In addition to the $72.4 million in hotels and accommodation loans which were downgraded to special mention, $22.4 million in hotels and accommodation loans were downgraded to impaired status. Park is closely monitoring the impact of COVID-19 on its borrowers ability to repay their loans in accordance with contractual terms. As additional information becomes available, management will continue to evaluate loans to ensure appropriate risk classification.
Impaired Loans: Park’s allowance for loan losses includes an allocation for loans specifically identified as impaired under U.S. GAAP. At September 30, 2020, 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 an amount different from management’s estimates.
Impaired commercial loans were $116.1 million at September 30, 2020, an increase of $38.7 million, compared to $77.5 million at December 31, 2019. The $116.1 million of impaired commercial loans at September 30, 2020 included $11.9 million of loans modified in a TDR which are currently on accrual status and performing in accordance with the restructured terms, up from $8.4 million at December 31, 2019.
At September 30, 2020, Park had taken partial charge-offs of $563,000 related to the $116.1 million of commercial loans considered to be impaired, compared to partial charge-offs of $719,000 related to the $77.5 million of impaired commercial loans at December 31, 2019.
Loans Acquired with Deteriorated Credit Quality: In conjunction with the NewDominion acquisition, Park acquired loans with deteriorated credit quality with a book value of $5.1 million which were recorded at the initial fair value of $4.9 million. In conjunction with the Carolina Alliance acquisition, Park acquired loans with deteriorated credit quality with a book value of $19.9 million which were recorded at the initial fair value of $18.4 million. The carrying amount of loans acquired with deteriorated credit quality at September 30, 2020 was $11.9 million, of which none were considered impaired due to additional credit deterioration or modification post acquisition. The $11.9 million were not included in impaired loan totals. The carrying amount of loans acquired with deteriorated credit quality at December 31, 2019 was $14.3 million, of which $5,000 was considered impaired due to additional credit deterioration or modification post acquisition. The remaining $14.3 million were not included in impaired loan totals.
Allowance for loan losses: Loss factors are reviewed quarterly and updated at least annually to reflect recent loan loss history and incorporate current risks and trends which may not be recognized in historical data.
For all loan types, management considers the following factors in determining loan collectability and the appropriate level of the allowance:
•Changes in the nature and volume of the portfolio and in the terms of loans, including:

Table of Contents
◦Trends (e.g., growth, reduction) in specific categories of the loan portfolio, as well as adjustments to the types of loans offered by PNB and GFSC.
◦Level of and trend in loan delinquencies, troubled loans, commercial watch list and impaired loans.
◦Level of and trend in new nonaccrual loans.
◦Level of and trend in loan charge-offs and recoveries.
•Changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, and recovery practices.
•Changes in national and local economic and business conditions and developments that affect the collectability of the portfolio.
•The effect of other external factors such as competition and legal and regulatory requirements on the level of estimated losses in Park's existing portfolio.
The judgmental increases discussed below 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.
Commercial Loans
Excluding acquired loans, the allowance for loan losses related to performing commercial loans was $55.8 million, or 1.49% of the outstanding principal balance of performing commercial loans at September 30, 2020. Excluding acquired loans, at September 30, 2020, the coverage level within the commercial loan portfolio was approximately 5.25 years compared to 3.40 years at December 31, 2019. Historical loss experience, defined as charge-offs plus changes in specific reserves, over the 120-month period ended December 31, 2019, for the commercial loan portfolio was 0.34%. This 120-month loss experience includes only the performance of the PNB loan portfolio and excludes the impact of PNB participations in Vision Bank loans.
Excluding acquired loans, the overall reserve of 1.49% for other accruing commercial loans breaks down as follows: PPP loans are reserved at 0.10%; pass-rated commercial loans are reserved at 1.64%; special mention commercial loans are reserved at 2.68%; and substandard commercial loans are reserved at 3.56%. The reserve levels for pass-rated, special mention and substandard commercial loans in excess of the 120-month loss experience of 0.34% are due to the following factors which management reviews on a quarterly or annual basis:
•Historical Loss Factor: Management updated the historical loss calculation during the fourth quarter of 2019, incorporating net charge-offs plus changes in specific reserves through December 31, 2019. With the addition of 2019 historical losses, management extended the historical loss period to 120 months from 108 months. The 120-month historical loss period captures all annual periods subsequent to June 2009, the end of the most recent recession, thus encompassing the full economic cycle to date.
•Loss Emergence Period Factor: At least annually, management calculates the loss emergence period for each commercial loan segment. The loss emergence period is calculated based upon the average period of time it takes from the probable occurrence of a loss event to the loan being moved to nonaccrual. If the loss emergence period for any commercial loan segment is greater than one year, management applies additional general reserves to all performing loans within that segment of the commercial loan portfolio. The loss emergence period was last updated in the fourth quarter of 2019.
During the third quarter of 2020, Park made the decision to extend the loss emergence period on all commercial loan types by six months. Management believes that the start of the COVID-19 pandemic in March 2020 represents the loss event. Management continues to refine estimated losses as a result of this March 2020 loss event. Approximately six months following the start of the pandemic, Park has experienced very little, if any, increase in delinquencies and charge-offs. Management believes that this is due to the unprecedented level of economic stimulus and CARES Act accommodations provided by the U.S. government which has delayed loan defaults and losses.
•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
89

Table of Contents
commercial loans graded special mention and substandard. Annually, management calculates a loss migration factor for each commercial loan segment for special mention and substandard credits based on a review of losses over the period of time a loan takes to migrate from pass-rated to impaired. The loss migration factor was last updated in the fourth quarter of 2019.
•Environmental Loss Factor: Management has identified certain macroeconomic factors that trend in accordance with losses in Park’s commercial loan portfolio. Certain environmental loss factors have been determined to correlate with higher charge-offs while other adjustments are based on a subjective evaluation of other environmental loss factors. Environmental factors applicable to the commercial loan portfolio include: the Ohio unemployment rate, percent change in Ohio GDP, the consumer confidence index, the prevalence of fixed rate loans in the portfolio and other environmental factors. In evaluating the ongoing relevance and amount of the other environmental factors, management considers: changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off and recovery practices, changes in national and local economic and business conditions, and developments that affect the collectability of the portfolio, and the effect of other external factors such as competition and legal and regulatory requirements on the level of estimated losses in Park's existing portfolio. All of these factors are evaluated in relation to the historical look back period. At September 30, 2020 and December 31, 2019, such subjective environmental loss factor inputs accounted for 39% and 42%, respectively, of the allowance for loan losses driven by environmental loss factors.
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. The environmental loss factors were updated in the first, second, and third quarters of 2020 to consider the economic impact of the COVID-19 pandemic. These factors were increased from 0.60% of applicable loans at December 31, 2019 to 0.675% of applicable loans at March 31, 2020 to 0.75% of applicable loans at June 30, 2020, and to 0.825% at September 30, 2020. The increase in the first and second quarters of 2020 was the result of upwards adjustments to the factors for Ohio unemployment, percent change in Ohio GDP and consumer confidence. The increase in the third quarter of 2020 was due to the increased uncertainty in the overall economic environment, the unknown length and severity of the pandemic and the limitations in the incurred loss model to capture all probable incurred losses during such uncertain times. Management will continue to evaluate this estimate of incurred losses as new information becomes available.
In addition to the increases in the environmental loss factor, in the second quarter, Park added additional reserves for three industries at particularly high risk due to the pandemic: hotels and accommodations, restaurants and food service, and strip shopping centers. These industries have had high levels of deferrals and have been particularly impacted by shut downs of non-essential businesses, increased health department regulations, and changes in consumer behavior. Management expects that a high percentage of the 4-rated credits in these portfolios will eventually migrate to special mention, substandard, or impaired status. As a result, additional reserves totaling $3.9 million were added for these portfolios on top of that already calculated. This amount was calculated by applying the loss factor for special mention credits to all 4-rated loans in these portfolios. A breakout of the 4-rated balances and additional reserve related to these portfolios is detailed in the following table.

| September 30, 2020
(in thousands) | 4-Rated Balance |  | 4-Rated Balance - Originated |  | 4-Rated Balance - Purchased |  | Additional Reserve
Hotels and accommodations | $ | 86,041 |  |  | $ | 85,050 |  |  | $ | 991 |  |  | $ | 1,435 |
Restaurants and food service | 34,263 |  |  | 28,291 |  |  | 5,972 |  |  | 658 |
Strip shopping centers | 181,517 |  |  | 158,790 |  |  | 22,727 |  |  | 1,789 |
Total | $ | 301,821 |  |  | $ | 272,131 |  |  | $ | 29,690 |  |  | $ | 3,882 |

Additionally, management applied a 1% reserve to all hotel loans in the general reserve population to account for increased valuation risk. At September 30, 2020, Park's originated hotels and accommodations loans had a balance of $178.8 million with an additional reserve specific to valuation risks of $1.8 million.
As of September 30, 2020, Park had $542.8 million of PPP loans which are included in the commercial, financial and agricultural portfolio segment. These loans are guaranteed by the SBA and thus have not been reserved for using the same methodology as the rest of Park’s loan portfolio. A 10 basis point reserve was calculated for these loans to reflect minimal credit risk.

Consumer Loans
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 120 months, through December 31, 2019. 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). Excluding acquired loans, at September 30, 2020, the coverage level within the consumer loan portfolio was approximately 2.38 years compared to 1.90 years at December 31, 2019. Historical loss experience, over the 120-month period ended December 31, 2019, for the consumer loan portfolio was 0.30%.
For the consumer portfolio, a specific COVID-19 factor was added to each segment equal to 50% of the 120-month historical loss factor. This increase considers the payment deferrals being provided to consumer loan customers as well as the likely delays in delinquencies and charge-offs as a result.
Much is still unknown about the economic impact of COVID-19, including the duration of the pandemic, future government programs that may be established as a result of the pandemic, and the resiliency of the U.S. economy. Management will continue to evaluate this estimate of incurred losses as new information becomes available. Given uncertainty about the magnitude and length of the COVID-19 pandemic and related economic shutdown, additional loan loss provisions may be required that would adversely impact earnings in future periods.
Purchased Loans
Loans acquired as part of the acquisitions of NewDominion and Carolina Alliance were recorded at fair value on the respective dates of acquisition. An allowance is only established on these loans as a result of credit deterioration post acquisition. At September 30, 2020, there was a $371,000 allowance related to performing acquired loans. At September 30, 2020, a reserve of $103,000 had been established related to PCI loans. At December 31, 2019, there was no allowance related to performing acquired loans, and a reserve of $268,000 related to PCI loans.
Current Expected Credit Losses: In June 2016, the FASB issued ASU 2016-13 - Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The new accounting guidance in this ASU replaces the incurred loss model with an expected loss model, which is referred to as the CECL model. The CECL model is applicable to the measurement of credit losses on financial assets measured at amortized cost, including loan receivables, HTM debt securities, and reinsurance receivables. It also applies to off-balance sheet credit exposures not accounted for as insurance (loan commitments, standby letters of credit, financial guarantees, and other similar instruments) and net investments in leases recognized by a lessor. The CECL model requires an entity to estimate credit losses over the life of an asset or off-balance sheet credit exposure. The new accounting guidance was to have been effective for Park for annual reporting periods and interim reporting periods within those annual periods, beginning after December 15, 2019.
Section 4014 of the CARES Act provides financial institutions with optional temporary relief from having to comply with the CECL methodology for estimating the allowance for credit losses. This temporary relief will expire on the earlier of the date on which the national emergency concerning the COVID-19 outbreak terminates or December 31, 2020, with adoption being effective retrospectively as of January 1, 2020.
Park elected to delay the implementation of CECL following the effectiveness of the CARES Act. The CECL standard requires financial institutions to calculate an allowance utilizing a reasonable and supportable forecast period which Park has established as a one-year period. Much is still unknown about the economic impact of COVID-19 including the duration of the pandemic, the duration and impact of future government programs that may be established as a result of the pandemic, and the resiliency of the U.S. economy, making any forecast subject to large fluctuations in the coming months. In this unprecedented situation, Park believes that adopting the CECL model in the first quarter 2020 would have added an unnecessary level of subjectivity and volatility to the calculation of the allowance for credit losses.
With the delay, management is currently evaluating the impact of the adoption of this new accounting guidance on Park's consolidated financial statements. Adoption will be applied through a one-time cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. Management has developed a quantitative credit model and is completing the process of validation. Management is still finalizing the analysis of qualitative factors to capture inherent risks which are not included within the quantitative credit model. Management, along with Park's

CECL Committee, is in the process of implementing the accounting, processes, controls and governance required to comply with the new accounting guidance.
Based on a preliminary analysis performed as of December 31, 2019 and forecasts of macroeconomic conditions and exposures as of December 31, 2019, the transition adjustment that was to have been effective January 1, 2020 was not expected to generate an allowance to loans ratio more than 120% of the then current recorded allowance at December 31, 2019. The Company is using a blend of multiple economic forecasts to estimate expected credit losses over a one-year reasonable and supportable forecast period and then revert, over a one-year period, to longer term historical loss experience to arrive at lifetime expected credit losses. The estimated increase in the allowance for credit losses as compared to Park's historical ALLL is primarily due to required increases for residential mortgage, home equity, and installment loans to address the requirement to estimate lifetime expected credit losses and the remaining length of time to maturity for these loans as well as an increase in reserves on acquired non-impaired loans which have low reserve levels under the incurred loss accounting guidance. Offsetting declines in the allowance are expected for commercial and commercial real estate loans due to their short-term nature. Additionally, management expects an increase in the allowance for credit losses for unfunded commitments.
While it is expected that the adoption of this ASU could increase the allowance for credit losses, many factors will determine the ultimate calculation at December 31, 2020. The adoption of this ASU will not, however, change the overall credit risk in the Company's loan, lease and investment securities portfolios or the ultimate losses therein. The transition adjustment to increase the allowance will primarily result in a decrease to shareholders' equity, net of income taxes. The ultimate impact of the adoption of this ASU will depend on the composition of the loan, lease and investment securities portfolios, finalization of credit loss models, and macroeconomic conditions and forecast that exist at the date of adoption.
On March 27, 2020, interagency guidance was released with respect to the CECL Interim Final Capital Rule which allows banks that adopt CECL as of January 1, 2020 to use a transitional amount in regulatory capital for eight quarters, followed by a three-year transition period to phase out the aggregate amount of such capital benefit. Park will be able to take advantage of this regulatory capital relief upon the adoption of ASU 2016-13.
Other Income
Other income increased by $8.4 million to $36.6 million for the quarter ended September 30, 2020, compared to $28.1 million for the third quarter of 2019 and increased by $17.0 million to $90.0 million for the first nine months of 2020, compared to $73.0 million for the first nine months of 2019. Other income was impacted by the acquisition of Carolina Alliance. The Carolina Alliance Bank Division contributed an aggregate of $6.2 million and $2.5 million to other income at Park for the nine months ended September 30, 2020 and 2019, respectively.
The increase for the three months ended September 30, 2020 compared to the three months ended September 30, 2019 was primarily due to increases in other service income; other components of net periodic pension benefit income; gain (loss) on sale of OREO, net; debit card fee income; and income from fiduciary activities, partially offset by declines in gain (loss) on equity securities, net; and service charges on deposit accounts.
The increase for the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019 was primarily due to increases in other service income; net gain (loss) on the sale of investment securities; other components of net periodic pension benefit income; debit card fee income; gain (loss) on sale of OREO, net; and income from fiduciary activities; partially offset by declines in gain (loss) on equity securities, net; and service charges on deposit accounts.

Income from fiduciary activities increased by $493,000, or 7.2%, to $7.3 million for the three months ended September 30, 2020, compared to $6.8 million for the same period of 2019, and increased $741,000, or 3.6%, to $21.2 million for the nine months ended September 30, 2020, compared to $20.5 million for the same period of 2019. Fiduciary fees charged are generally based on the market value of customer accounts. The average market value for assets under management for the nine months ended September 30, 2020 was $6,023 million compared to $5,756 million for the nine months ended September 30, 2019.
Service charges on deposit accounts decreased by $746,000, or 26.0%, to $2.1 million for the three months ended September 30, 2020, compared to $2.9 million for the same period of 2019, and decreased $1.8 million, or 21.7%, to $6.3 million for the nine months ended September 30, 2020, compared to $8.1 million for the same period of 2019. The declines were largely a result of a decline in non-sufficient funds (NSF) fee income.
Other service income increased by $8.8 million, to $13.0 million for the three months ended September 30, 2020, compared to $4.2 million for the same period of 2019, and increased by $14.5 million, to $25.6 million for the nine months ended September 30, 2020, compared to $11.1 million for the same period of 2019. The primary reasons for the increase for the three months ended September 30, 2020 were a $6.9 million increase in fee income related to mortgage loan originations to be sold in the secondary market, and a $1.7 million increase in mortgage servicing rights income. The primary reasons for the increase for the nine months ended September 30, 2020 were a $10.1 million increase in fee income related to mortgage loan originations to be sold in the secondary market, a $2.8 million increase in income related to investor rate locks and loans held for sale, and a $1.2 million increase in mortgage servicing rights income. Mortgage origination volume increased by $537.8 million for the nine months ended September 30, 2020, compared to the same period of 2019.
Debit card fee income increased $540,000, or 10.2%, to $5.9 million for the three months ended September 30, 2020, compared to $5.3 million for the same period in 2019, and increased $1.5 million, or 9.8%, to $16.4 million for the nine months ended September 30, 2020, compared to $14.9 million for the same period in 2019. The increase in 2020 was attributable to a continued increase in the volume of debit card transactions and changes in Park's point of sale network. The sales volume of debit card transactions for the nine months ended September 30, 2020 increased 12.9% from the same period in 2019.
Gain (loss) on sale of OREO, net increased by $622,000, to a net gain of $569,000 for the three months ended September 30, 2020, compared to a net loss of $53,000 for the same period of 2019, and increased by $1.4 million, to a net gain of $1.2 million for the nine months ended September 30, 2020, compared to a net loss of $224,000 for the same period of 2019. The increase for the three months ended September 30, 2020 was primarily due to a $379,000 gain on the sale of one OREO property at SEPH, and the increase during first nine months of 2020 was the result of a $1.2 million gain on the sale of two OREO properties during the first nine months of 2020, one of which was participated to PNB from SEPH.

The increase for the three-month period was due to a $1.0 million increase in officer incentive compensation expense, a $479,000 increase in additional compensation expense and a $250,000 increase in vacation accrual expense, partially offset by a $764,000 decrease in salary expense. The increase for the nine-month period was due to a $2.4 million increase in salary expense, of which $982,000 was related to the addition of employees of the Carolina Alliance Bank Division, and a $250,000 increase in vacation accrual expense, partially offset by a $462,000 decrease in additional compensation expense. The changes in additional compensation expense for both the three-month and nine-month periods was primarily related to one-time merger expense for both the three and nine months ended September 30, 2019 of $546,000 and $3.2 million, respectively, which was offset by increased additional compensation expense related to increased mortgage originations and other incentive programs for the three and nine months ended September 30, 2020. Included in salary expense for the three-month and nine-month periods ended September 30, 2020 is $744,000 and $2.9 million of calamity pay and special one-time bonuses to certain associates as a result of the COVID-19 public health crisis.
Employee benefits increased $2.0 million, or 7.1%, to $29.8 million for the nine months ended September 30, 2020, compared to $27.8 million for the same period in 2019.

The increases for both the three-month and nine-month periods ended September 30, 2020 were primarily related to increased depreciation expense and rental expense related to the write-down of right-of-use lease assets.
Furniture and equipment expense increased by $510,000, or 12.2%, to $4.7 million for the three months ended September 30, 2020, compared to $4.2 million for the same period in 2019, and increased $1.1 million, or 9.0%, to $13.9 million for the nine months ended September 30, 2020, compared to $12.7 million for the same period in 2019.

The increase in professional fees and services expense for the three months ended September 30, 2020 was due to increases in management and consulting fees and increased costs related to loan origination volume. The decrease in professional fees and services expense for the nine months was largely related to a $2.5 million decrease in system conversion costs related to the Carolina Alliance acquisition, as well temporary wages, partially offset by increased management and consulting expense and increased costs related to loan origination volume.
Insurance expense increased by $1.3 million, to $1.5 million for the three months ended September 30, 2020, compared to $276,000 for the same period in 2019, and increased $1.8 million for the nine months ended September 30, 2020, compared to $2.8 million for the same period in 2019. The increase for both the three months and nine months ended September 30, 2020 was related to a $1.1 million FDIC assessment credit which had been utilized for the FDIC expense for the three months ended September 30, 2019 (and not repeated in 2020), as well as increased FDIC insurance costs, due to both an increased assessment base and rate.

Items Impacting Comparability
From time to time, revenue, expenses, and/or taxes are impacted by items judged by management of Park to be outside of ordinary banking activities and/or by items that, while they may be associated with ordinary banking activities, are so unusually large that their outsized impact is believed by management of Park at that time to be infrequent or short-term in nature. Most often, these items impacting comparability of period results result from merger and acquisition activities and revenue and expenses related to former Vision Bank loan relationships. In other cases, they may result from management's decisions associated with significant corporate actions outside of the ordinary course of business.
The following table details those items which management believes impact the comparability of current and prior period amounts.

Income Tax
Income tax expense was $5.9 million for the third quarter of 2020 and $6.4 million the third quarter of 2019. The effective income tax rate for the third quarter of 2020 was 16.0%, compared to 17.0% for the same period in 2019. Income tax expense was $16.4 million for the first nine months of 2020 and $15.8 million for the first nine months of 2019. The effective income tax rate for the first nine months of 2020 was 16.6%, compared to 16.7% for the same period in 2019. The difference between the statutory federal corporate income tax rate of 21% and Park's effective income tax rate reflects permanent tax differences, primarily consisting of tax-exempt interest income from municipal investments and loans, qualified affordable housing and historical tax credits, bank owned life insurance income, and dividends paid on the common shares held within Park's salary deferral plan. Park expects permanent federal income tax differences for the 2020 year will be approximately $6.5 million.

•Accumulated other comprehensive income (loss), net of taxes improved by $23.8 million during the period as a result of unrealized net holding gains on AFS debt securities, net of taxes, of $26.7 million, partially offset by a realized gain on sale of securities, net of taxes, of $2.6 million and an unrealized loss on cash flow hedging derivatives, net of taxes, of $357,000.
•Retained earnings increased by $29.6 million during the period primarily as a result of net income of $82.7 million, partially offset by common share dividends of $53.8 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 $52.4 million and $74.0 million for the nine months ended September 30, 2020 and 2019, respectively. Net income was the primary source of cash from operating activities for each nine-month period ended September 30, 2020.

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 $727.4 million for the nine months ended September 30, 2020 and was $112.8 million for the nine months ended September 30, 2019.
Cash provided by financing activities was $566.1 million and $13.8 million for the nine months ended September 30, 2020 and 2019, respectively. A major source of cash for financing activities is the net change in deposits. Deposits increased and provided $423.4 million and $275.2 million of cash for the nine months ended September 30, 2020 and 2019, respectively. Another major source/use of cash from financing activities is borrowings in the form of short-term borrowings, long-term debt and subordinated notes.

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 capital markets, the investment securities portfolio, the core deposit base, FHLB borrowings, the capability to securitize or package loans for sale, and a $15.0 million revolving line of credit with another financial institution, which had no outstanding balance as of September 30, 2020. The Corporation’s loan to asset ratio was 78.77% at September 30, 2020, compared to 75.97% at December 31, 2019 and 73.41% at September 30, 2019. Cash and cash equivalents were $246.7 million at September 30, 2020, compared to $160.0 million at December 31, 2019 and $372.7 million at September 30, 2019. 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 September 30, 2020 was $1,017.0 million, or 11.0% of total assets, compared to $969.0 million, or 11.3% of total assets, at December 31, 2019 and $956.1 million, or 11.0% of total assets, at September 30, 2019.
Financial institution regulators have established guidelines for minimum capital ratios for banks, thrifts and bank holding companies. Park has elected not to include the net unrealized gain or loss on AFS debt securities in computing regulatory capital. During the first quarter of 2015, Park adopted the Basel III regulatory capital framework as approved by the federal banking agencies. The adoption of this framework modified the calculation of the various capital ratios, added an additional ratio, common equity tier 1, and revised the adequately and well-capitalized thresholds under the prompt corrective action regulations applicable to PNB. Additionally, under this framework, in order to avoid limitations on capital distributions, including dividend payments and stock repurchases, Park must hold a capital conservation buffer above the adequately capitalized risk-based capital ratios. The capital conservation buffer was fully phased in at 2.50% on January 1, 2019. The amounts shown below as the adequately capitalized ratio plus capital conservation buffer includes the 2.50% buffer. The Federal Reserve Board also adopted requirements Park must maintain to be deemed "well-capitalized" and remain a financial holding company.
Park and PNB met each of the well capitalized ratio guidelines applicable to them at September 30, 2020. The following table indicates the capital ratios for PNB and Park at September 30, 2020 and December 31, 2019.

| As of September 30, 2020
| Leverage |  | Tier 1 Risk-Based |  | Common Equity Tier 1 |  | Total Risk-Based

| As of December 31, 2019

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 71 of Park’s 2019 Form 10-K (Table 35) for disclosure concerning contractual obligations and commitments at December 31, 2019. On August 20, 2020, Park completed the issuance and sale of $175.0 million aggregate principal amount of its 4.50% Fixed-to-Floating Rate Subordinated Notes due 2030. There were no other significant changes in contractual obligations and commitments during the first nine months of 2020.
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,
100

Table of Contents
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) |  | September 30, 2020 |  | December 31, 2019
Loan commitments |  | $ | 1,398,438 |  |  | $ | 1,309,896 |
Standby letters of credit |  | $ | 16,801 |  |  | $ | 17,195 |

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 70 of Park’s 2019 Form 10-K.
On page 70 (Table 34) of Park’s 2019 Form 10-K, management reported that Park’s twelve-month cumulative rate sensitivity gap was a positive (assets exceeding liabilities) $302.6 million or 3.89% of total interest earning assets at December 31, 2019. At September 30, 2020, Park’s twelve-month cumulative rate sensitivity gap was a positive (assets exceeding liabilities) $591.2 million or 7.0% 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 71 of Park’s 2019 Form 10-K, management reported that at December 31, 2019, the earnings simulation model projected that net income would decrease by 1.9% using a rising interest rate scenario and increase by 0.5% using a declining interest rate scenario over the next year. At September 30, 2020, the earnings simulation model projected that net income would decrease by 3.7% using a rising interest rate scenario and would decrease by 9.6% in a declining interest rate scenario. At September 30, 2020, 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 (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 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 the 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 its 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-15(f) under the Exchange Act) that occurred during Park’s quarter ended September 30, 2020, 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
There are no pending legal proceedings to which Park or any of its subsidiaries is a party or to which any of their property is subject, except for routine legal proceedings which Park's subsidiaries are parties to incidental to their respective businesses. Park considers none of those proceedings to be material.
Item 1A. Risk Factors
There are certain risks and uncertainties in our business that could cause Park's actual results to differ materially from those anticipated. In “ITEM 1A. RISK FACTORS” of Part I of Park’s 2019 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 Park's business and in connection with the forward-looking statements contained in this Quarterly Report on Form 10-Q. Any of the risks described in Park's 2019 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. In the first quarter of 2020, we identified the following additional risk factor which continues to apply to the third quarter of 2020:
Our business, financial condition, liquidity and results of operations have been, and will likely continue to be, adversely affected by the COVID-19 pandemic.
The COVID-19 pandemic has created economic and financial disruptions that have adversely affected, and are likely to continue to adversely affect, our business, financial condition, liquidity and results of operations. The extent to which the COVID-19 pandemic will continue to negatively affect our business, financial condition, liquidity and results of operations will depend on future developments, which are highly uncertain and cannot be predicted, including the scope and duration of the pandemic, the continued effectiveness of our business continuity plan (including work-from-home arrangements and staffing in operational facilities), the direct and indirect impact of the pandemic on our employees, customers, clients, counterparties and service providers, as well as other market participants, and actions taken by governmental authorities and other third parties in response to the pandemic.
The COVID-19 pandemic has contributed to:
•Increased unemployment and decreased consumer confidence and business generally, leading to an increased risk of delinquencies, defaults and foreclosures.
•Ratings downgrades, credit deterioration and defaults in many industries, including, in particular, hotels and accommodations, restaurants and food service, and strip shopping center industries, as to which Park has already entered into modification as described under "Loan Modifications" within the "COVID-19 Considerations" discussion in Item 2 - Management's Discussion and Analysis of Financial Condition and Results of Operations within this Quarterly Report on Form 10-Q.
•A sudden and significant reduction in the valuation of the equity, fixed-income and commodity markets and the significant increase in the volatility of those markets.
•A decrease in the rates and yields on U.S. Treasury securities and the Federal Reserve target for the federal funds rate which may lead to decreased net interest income.
•Draws on credit lines as customers and clients seek to increase liquidity.
•Increased demands on capital and liquidity and potentially the ability to fund liquidity through historical means.
•A reduction in the value of the assets that the Company manages or otherwise administers or services for others, affecting related fee income and demand for the Company’s services.
•Heightened cybersecurity, information security and operational risks as a result of work-from-home arrangements.
Governmental authorities have taken unprecedented measures to provide economic assistance to individual households and businesses, stabilize the markets and support economic growth. The success of these measures is unknown and they may not be sufficient to fully mitigate the negative impact of the COVID-19 pandemic. Additionally, some measures, such as a suspension of mortgage and other loan payments and foreclosures, may have a negative impact on our business, financial condition, liquidity and results of operations. We also face an increased risk of litigation and governmental and regulatory scrutiny as a result of the effects of COVID-19 on market and economic conditions, actions governmental authorities take in response to those conditions, and our participation in government programs, such as the PPP.

Table of Contents
The length of the pandemic and the efficacy of the extraordinary measures being put in place to address it are unknown. Until the pandemic subsides, we expect continued draws on lines of credit, reduced revenues and increased customer and client defaults, including defaults on unsecured loans. Even after the pandemic subsides, the global and U.S. economy may continue to experience a recession, and we anticipate our businesses would be materially and adversely affected by a prolonged recession. To the extent the pandemic adversely affects our business, financial condition, liquidity or results of operations, it may also have the effect of heightening many of the other risks described in the section entitled “Risk Factors” in our 2019 Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q.
Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

(1)The number shown represents, as of the end of each period, the maximum number of common shares that may yet be purchased as part of Park’s publicly announced stock repurchase authorizations to fund the 2017 Employees LTIP and to fund the 2017 Non-Employee Directors LTIP, both of which became effective on April 24, 2017; Park's stock repurchase authorization covering 500,000 common shares which was announced on January 23, 2017; and Park's stock repurchase authorization covering 500,000 common shares which was announced on January 28, 2019 and as to which approval from the Federal Reserve was obtained in the form of correspondence from the Federal Reserve Bank dated April 19, 2019.
At the 2017 Annual Meeting of Shareholders held on April 24, 2017, Park's shareholders approved the 2017 Employees LTIP and the 2017 Non-Employee Directors LTIP. The common shares to be issued and delivered under the 2017 Employees LTIP and the 2017 Non-Employee Directors LTIP may consist of either common shares currently held or common shares subsequently acquired by Park as treasury shares. No newly-issued common shares will be delivered under the 2017 Employees LTIP or the 2017 Non-Employee Directors LTIP. On April 24, 2017, Park's Board of Directors authorized the purchase, from time to time, of up to 750,000 common shares and 150,000 common shares, respectively, to be held as treasury shares for subsequent issuance and delivery under the 2017 Employees LTIP and the 2017 Non-Employee Directors LTIP.
On January 23, 2017, the Park Board of Directors authorized Park to purchase, from time to time, up to an aggregate of 500,000 Common Shares. On January 28, 2019, the Park Board of Directors authorized Park to repurchase, from time to time following receipt of any required approval from the Federal Reserve, up to 500,000 Park common shares in addition to the 500,000 Park common shares which had been authorized for repurchase by the Park Board of Directors on January 23, 2017 and remained available for repurchase as of January 28, 2019. The required approval was received by Park in the form of correspondence from the Federal Reserve Bank of Cleveland dated April 19, 2019.
Purchases may be made through NYSE AMERICAN, in the over-the-counter market or in privately negotiated transactions, in each case in compliance with applicable laws and regulations and the rules applicable to issuers having securities listed on NYSE AMERICAN. Purchases will be made upon such terms and conditions and at such times and in such amounts as any one or more of the authorized officers of Park deem to be appropriate, subject to market conditions, regulatory requirements and other factors, and in the best interest of Park and Park's shareholders.
