Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation: The accompanying Unaudited Consolidated Financial Statements of Peoples Bancorp Inc. and its subsidiaries ("Peoples" refers to Peoples Bancorp Inc. and its consolidated subsidiaries collectively, except where the context indicates the reference relates solely to Peoples Bancorp Inc.) have been prepared in accordance with accounting principles generally accepted in the United States ("US GAAP") for interim financial information and the instructions for Form 10-Q and Article 10 of Regulation S-X. Accordingly, these financial statements do not contain all of the information and footnotes required by US GAAP for annual financial statements and should be read in conjunction with Peoples’ Annual Report on Form 10-K for the fiscal year ended December 31, 2019 ("Peoples' 2019 Form 10-K"). The accounting and reporting policies followed in the presentation of the accompanying Unaudited Consolidated Financial Statements are consistent with those described in "Note 1 Summary of Significant Accounting Policies" of the Notes to the Consolidated Financial Statements included in Peoples’ 2019 Form 10-K, as updated by the information contained in this Form 10-Q. Management has evaluated all significant events and transactions that occurred after September 30, 2020 for potential recognition or disclosure in these unaudited consolidated financial statements. In the opinion of management, these unaudited consolidated financial statements reflect all adjustments necessary to present fairly such information for the periods and at the dates indicated. Such adjustments are normal and recurring in nature. Intercompany accounts and transactions have been eliminated. The Consolidated Balance Sheet at December 31, 2019, contained herein, has been derived from the audited Consolidated Balance Sheet included in Peoples’ 2019 Form 10-K. The preparation of the consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Results of operations for interim periods are not necessarily indicative of the results to be expected for the full year, due in part to seasonal variations and unusual or infrequently occurring items. New Accounting Pronouncements: From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board ("FASB") or other standard setting bodies that are adopted by Peoples as of the required effective dates. The following should be read in conjunction with "Note 1 Summary of Significant Accounting Policies" of the Notes to the Consolidated Financial Statements included in Peoples’ 2019 Form 10-K. Unless otherwise discussed, management believes the impact of any recently issued standards, including those issued but not yet effective, will not have a material impact on Peoples' financial statements taken as a whole. Accounting Standards Update ("ASU") 2020-04 - Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This guidance provides optional expedients and exceptions for applying US GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. This update is effective as of March 12, 2020 through December 31, 2022. Per the guidance, Peoples is continuing to evaluate the impact of ASU 2020-04 on Peoples' consolidated financial statements. ASU 2016-13 - Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This accounting guidance replaces the "incurred loss" model for recognizing credit losses with an "expected loss" model, referred to as the Current Expected Credit Loss ("CECL") model. Under the CECL model, Peoples is required to present certain financial assets carried at amortized cost, such as loans held-for-investment and held-to-maturity investment securities, at the net amount expected to be collected. ASU 2018-19 clarified that receivables arising from operating leases are not within the scope of Accounting Standards Codification ("ASC") 326-20, and should be accounted for according to ASC 842. The measurement of expected credit losses is to be based on information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The measurement is to take place at the time the financial asset is first added to the balance sheet and periodically thereafter. This differs significantly from the "incurred loss" model under previous US GAAP accounting guidance, which delayed recognition until it was probable a loss had been incurred. Peoples adopted ASU 2016-13 using the modified retrospective method for all financial assets measured at amortized cost on January 1, 2020. Reporting periods beginning after December 31, 2019 are presented as required by ASU 2016-13, while prior period amounts continue to be reported in accordance with previously applicable US GAAP requirements. Peoples is using the prospective transition approach for financial assets purchased with credit deterioration that were previously classified as purchased credit impaired assets and accounted for under ASC 310-30. As of January 1, 2020, Peoples recorded a one-time cumulative-effect adjustment to reduce retained earnings by $3.7 million, net of statutory corporate federal income taxes, an increase in allowance for credit losses of $5.8 million and an increase in unfunded commitment liability of $1.5 million. On January 1, 2020, the amortized cost basis of the purchased credit deteriorated assets was adjusted to reflect the addition of $2.6 million to establish the allowance for credit losses. The remaining interest-related discount is being accreted into interest income at the effective interest rate beginning on January 1, 2020. As of January 1, 2020, Peoples did not record an allowance for credit losses for available-for-sale investment securities, as all unrealized losses on these securities were deemed to be non-credit in nature, with no credit deterioration upon review by Peoples. Peoples recorded an allowance for credit losses for held-to-maturity securities of $7,000 as of January 1, 2020. The following table illustrates the impact on the allowance for credit losses from the adoption of ASU 2016-13: (Dollars in thousands) As Reported Under ASC 326 January 1, 2020 Pre-ASC 326 Adoption December 31, 2019 Impact of ASC 326 Adoption Assets: Loans, at amortized cost $ 2,876,147 $ 2,873,525 $ 2,622 Allowance for credit losses on loans: Construction 651 1,188 (537) Commercial real estate, other 8,549 6,560 1,989 Commercial and industrial 5,820 8,568 (2,748) Residential real estate 4,360 1,296 3,064 Home equity lines of credit 1,572 612 960 Consumer, indirect 5,389 2,942 2,447 Consumer, direct 890 296 594 Deposit account overdrafts 94 94 — Allowance for credit losses on loans 27,325 21,556 5,769 Liabilities: Allowance for credit losses for unfunded commitments $ 1,495 $ — $ 1,495 Investment Securities: Investment securities are recorded initially at cost, which includes premiums and discounts if purchased at other than par or face value. Peoples amortizes premiums and accretes discounts as an adjustment to interest income on a level yield basis. The cost of investment securities sold, excluding equity investment securities, and any resulting gain or loss, is based on the specific identification method and recognized as of the trade date. The cost of equity investment securities is based on the weighted-average method. Peoples determines the appropriate classification of investment securities at the time of purchase. Held-to-maturity securities are those securities that Peoples has the positive intent and ability to hold to maturity and are recorded at amortized cost. Available-for-sale securities are those securities that would be available to be sold in the future in response to Peoples' liquidity needs, changes in market interest rates, and asset-liability management strategies, among other considerations. Available-for-sale securities are reported at fair value, with unrealized gains and losses reported in total stockholders' equity as a separate component of accumulated other comprehensive income or loss, net of applicable deferred income taxes. Certain restricted equity investment securities that do not have readily determinable fair values and for which Peoples does not exercise significant influence, are carried at cost. These cost method securities are reported in other investment securities on the Unaudited Consolidated Balance Sheets and consist primarily of shares of the Federal Home Loan Bank of Cincinnati (the "FHLB") and the Federal Reserve Bank of Cleveland (the "FRB"). Peoples evaluates available-for-sale investment securities on a quarterly basis to determine how much, if any, allowance for credit losses is required. Peoples reviews available-for-sale investment securities at an unrealized loss position, with potential exposure to a credit event (which excludes U.S. government and U.S. government sponsored agency securities) to determine if the unrealized loss was credit-related. An allowance for credit losses is recorded to the extent that the unrealized losses are credit-related and likely to be permanent. Peoples evaluates held-to-maturity investment securities on a quarterly basis in determining an allowance for credit losses. Peoples has determined that the loss given default for U.S. government sponsored enterprise investment securities is zero, due to the fact that it is unlikely the ultimate guarantor (the U.S. government) would not perform on its implicit guarantee in the event of default. The remaining securities are included in the calculation of the allowance for credit losses for held-to-maturity investment securities. Loans: Loans originated that Peoples has the positive intent and ability to hold for the foreseeable future or to maturity or payoff are reported at the principal balance outstanding, net of deferred loan fees and costs, purchase premiums and discounts, charge-offs and an allowance for credit losses. The foreseeable future is based upon current market conditions and business strategies, as well as balance sheet management and liquidity. As the conditions change, so may management's view of the foreseeable future. Peoples considers loans past due if any required principal and interest payments have not been received as of the date such payments were required to be made under the terms of the loan agreement. Upon detection of the reduced ability of a borrower to meet cash flow obligations, consumer and residential real estate loans are typically charged down to the net realizable value, with the residual balance placed on nonaccrual status. Loans deemed to be uncollectable are charged against the allowance for credit losses, while recoveries of previously charged off amounts are credited to the allowance for credit losses. Loans acquired in a business combination that have evidence of more than insignificant credit deterioration, which includes loans that Peoples believes it is probable that Peoples will be unable to collect all contractually required payments, are considered "purchased credit deteriorated" loans. These loans are recorded at the purchase price, and an allowance for credit losses is determined using the same methodology as for other loans. The initial allowance for credit losses determined on a collective basis is allocated to individual loans. The total of the purchase price and allowance for credit losses is the initial amortized cost basis of these loans. The variance between the initial amortized cost basis and the par value of the loan is considered an interest premium or discount, which is amortized or accreted into interest income on a level yield method over the life of the loan. Loans acquired in a business combination that are not considered purchased credit deteriorated are recorded at the fair value and the difference between the acquisition date fair value and the contractual amounts due at the acquisition date represents the discount or premium to a loan's cost basis and is accreted or amortized to interest income over the loan's remaining life using the level yield method. Allowance for Credit Losses: The allowance for credit losses is a valuation reserve established through the provision for credit losses charged against income. The allowance for credit losses is estimated by management using relevant available information, from both internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. The allowance for credit losses is measured on a pool basis, with loans collectively evaluated when similar risk characteristics exist. Peoples evaluated risk characteristics, including but not limited to: internal or third-party credit scores or credit ratings, risk ratings or classifications, financial asset type, collateral type, size, effective interest rate, term, geographical location, industry of the borrower, vintage, historical or credit loss patterns and reasonable and supportable forecast periods. Peoples identified 17 segments for which it believes there are similar risk characteristics and utilized a discounted cash flow methodology in determining an allowance for credit losses for each segment. In estimating credit losses, Peoples uses a loss driver method, which analyzes one or more economic variables to the change in default rate using a regression analysis. Variables that had a strong correlation were selected as economic factors, or variables, for the model. If a single variable was not found to be strongly correlated, additional variables were included. Peoples utilizes the U.S. unemployment, Ohio unemployment, Ohio Gross Domestic Product, and the Ohio Case Shiller Home Price Indices as economic factors in modeling. Probabilities of default are used in the loss driver model, and are analyzed on a quarterly basis to assess reasonableness. Peoples measured loss given default at the segment level due to statistical considerations using historical information. Peoples also utilized peer data due to somewhat volatile loss history in certain segments to normalize default curves, which provided more meaningful results. Peoples modeled amortizing loans with a prepayment rate annualized to one year. The prepayment rates were calculated using Peoples' historical data, at the segment level. Peoples models extensions of contractual terms in the following situations: when a loan is 60 days or more past due, when a partial charge-off has occurred, if the loan is in non-accrual status, if a troubled debt restructuring ("TDR") has occurred, or if the loan is grade 5 or higher. When any of these criteria are met and the loan matures within the next 12 months, the loan will be modeled to extend for an additional 12 months. In general, Peoples completes a quarterly evaluation based on several qualitative factors to determine if there should be adjustments made to the allowance for credit losses. These factors include economic conditions, collateral, concentrations, troubled assets, Peoples' loss trends, peer loss trends, delinquency trends, portfolio composition and loan growth, underwriting, and certain other risks. The allowance for credit losses related to specific loans was based on management's estimate of potential losses on impaired loans as determined by (1) the present value of expected future cash flows, (2) the fair value of collateral if the loan is determined to be collateral dependent, or (3) the loan's observable market price. Peoples categorized loans involving commercial borrowers into risk categories based upon an established grading matrix. This system was used to manage the risk within Peoples' commercial lending activities, evaluate changes in the overall credit quality of the loan portfolio and evaluate the appropriateness of the allowance for credit losses. Loan grades are assigned at the time a new loan or lending commitment is extended by Peoples and may be changed at any time when circumstances warrant. Loans to borrowers with an aggregate unpaid principal balance in excess of $1 million are reviewed at least on an annual basis for possible credit deterioration. Loan relationships whose aggregate credit exposure to Peoples is equal to or less than $1 million are reviewed at least on an event driven basis. Triggers for review include knowledge of adverse events affecting the borrower's business, receipt of financial statements indicating deteriorating credit quality or other similar events. Adversely classified loans are reviewed on a quarterly basis. The primary factors considered when assigning a risk grade to a loan include (1) reliability and sustainability of the primary source of repayment, (2) past, present and projected financial condition of the borrower, and (3) current economic and industry conditions. Other factors that could influence the risk grade assigned include the type and quality of collateral and the strength of any guarantors. The primary source of repayment for commercial real estate loans and commercial and industrial loans is normally the operating cash flow of the business available to repay debt. Management's analysis of operating cash flow for commercial real estate loans secured by non-owner occupied properties takes into account factors such as rent rolls and vacancy statistics. Management's analysis of operating cash flow for commercial real estate loans secured by owner occupied properties and all commercial and industrial loans considers the profitability, liquidity and leverage of the business. The evaluation of construction loans includes consideration of the borrower's ability to complete construction within the established budget. The primary factors considered when classifying residential real estate, home equity lines of credit and consumer loans include the loan's past due status and declaration of bankruptcy by the borrower(s). The classification of residential real estate and home equity lines of credit also takes into consideration the current value of the underlying collateral. Peoples has elected the practical expedient not to measure allowance for credit losses for accrued interest receivables. Unfunded Commitments: Peoples also completes a quarterly evaluation for unfunded commitments for loans that are not conditionally cancellable, which includes construction loans, floor plan lines of credit, home equity lines of credit, other credit lines and letters of credit. Peoples performed a study to determine the historical funding rates of unadvanced portions of loans, and applied these funding rates to the unfunded commitments at period end. The loss rates, including qualitative factors, in determining the allowance for credit losses were applied at the segment level to the unfunded commitment amount to determine the allowance for credit loss liability for unfunded commitments. Troubled Debt Restructuring ("TDR"): The restructuring of a loan is considered a TDR if both (1) the borrower is experiencing financial difficulties and (2) the creditor has granted a concession. Loans acquired that are restructured after acquisition are not considered TDRs if the loans evidenced credit deterioration as of the acquisition date and are accounted for in pools of purchased credit deteriorated loans. In assessing whether or not a borrower is experiencing financial difficulties, Peoples considers information currently available regarding the financial condition of the borrower. This information includes, but is not limited to, whether (1) the borrower is currently in payment default on any of the borrower's debt; (2) a payment default is probable in the foreseeable future without the modification; (3) the borrower has declared or is in the process of declaring bankruptcy; and (4) the borrower's projected cash flow is insufficient to satisfy contractual payments due under the original terms of the loan without a modification. Peoples considers all aspects of the modification to loan terms to determine whether or not a concession has been granted to the borrower. Key factors considered by Peoples include the borrower's ability to access funds at a market rate for loans with similar risk characteristics, the significance of the modification relative to the unpaid principal loan balance or collateral value underlying the loan, and the significance of a delay in the timing of payments relative to the original contractual terms of the loan. The most common concessions granted by Peoples generally include one or more modifications to the terms of the loan, such as (1) a reduction in the interest rate for the remaining life of the loan, (2) an extension of the maturity date at an interest rate lower than the current market rate for a new loan with similar risk, (3) a temporary period of interest-only payments, and (4) a reduction in the contractual payment amount for either a short period or the remaining term of the loan. All TDRs are evaluated individually to determine if a write-down is required and if they should be on accrual or nonaccrual status. On March 22, 2020, federal and state banking regulators issued a joint statement, with which the FASB concurred as to the approach, regarding accounting for loan modifications for borrowers affected by COVID-19. In this guidance, short-term modifications, made on a good faith basis in response to COVID-19, to borrowers who were current prior to any relief, are not considered TDRs. This includes short-term modifications such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment which are insignificant. Under the guidance, borrowers that are considered current are those that are less than 30 days past due on their contractual payments at the time a modification program is implemented. In addition, modification or deferral programs mandated by the U.S. federal government or any state government related to COVID-19 are not in the scope of accounting for troubled debt restructurings defined in ASC 310-40. Based on this guidance, Peoples does not classify COVID-19 loan modifications as TDRs. On August 3, 2020, federal and state banking regulators issued a joint statement, encouraging financial institutions to consider prudent accommodation options to mitigate losses for the borrower and financial institution beyond the initial accommodation period. In this guidance, institutions should also provide consumers with available options for repaying missed payments at the end of their accommodation to avoid delinquencies, as well as options for changes to terms to support sustainable and affordable payments for the long term. These considerations should also include prudent risk management practices at the financial institution based on the credit risk of the borrower. Peoples is actively working with its customers to address any further accommodation needs while carefully evaluating the associated credit risk of the borrowers. Nonaccrual loans: Peoples discontinues the accrual of interest on a loan when conditions cause management to believe collection of all or any portion of the loan's contractual interest is doubtful. Such conditions may include the borrower being 90 days or more past due on any contractual payments, or current information regarding the borrower's financial condition and repayment ability. All unpaid accrued interest deemed uncollectable is reversed, which reduces Peoples' net interest income. Interest received on nonaccrual loans is included in income only if principal recovery is reasonably assured. Under the Coronavirus Aid, Relief and Economic Security ("CARES") Act, borrowers who were making payments as required and were not considered past due prior to becoming affected by COVID-19 and then receive payment accommodations as a result of the effects of COVID-19 generally would not be reported as past due. If Peoples agrees to a payment deferral for a borrower under the CARES Act, this may result in no contractual payments being past due, and the loans are not considered past due during the period of the deferral. During the time that Peoples maintains these short-term arrangements with borrowers, under the guidance, it is not to report the loans as nonaccrual. Interest Income Recognition: Interest income on loans and investment securities is recognized by methods that result in level rates of return on principal amounts outstanding. This includes yield adjustments resulting from the amortization of premiums on investment securities, loan costs and premiums, and accretion of discounts on investment securities, loan fees and discounts. Loans that have been placed on nonaccrual, and are subsequently returned to accruing status, recognize interest income similar to other accruing loans once they return to accruing status. Prior accrued interest that was reversed when the loan was placed on nonaccrual is recognized when received, after all of the principal of the loan outstanding has been paid. Since mortgage-backed securities comprise a sizable portion of Peoples' investment portfolio, a significant increase in principal payments on those securities can impact interest income due to the corresponding acceleration of premium amortization or discount accretion.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Assets and Liabilities Fair value represents the amount expected to be received to sell an asset or paid to transfer a liability in its principal or most advantageous market in an orderly transaction between market participants at the measurement date. In accordance with fair value accounting guidance, Peoples measures, records and reports various types of assets and liabilities at fair value on either a recurring or a non-recurring basis in the Consolidated Financial Statements. Those assets and liabilities are presented below in the sections entitled “Assets and Liabilities Required to be Measured and Reported at Fair Value on a Recurring Basis” and “Assets and Liabilities Required to be Measured and Reported at Fair Value on a Non-Recurring Basis.” Depending on the nature of the asset or liability, Peoples uses various valuation methodologies and assumptions to estimate fair value. The measurement of fair value under US GAAP uses a hierarchy, which is described in "Note 1 Summary of Significant Accounting Policies" of the Notes to the Consolidated Financial Statements included in Peoples' 2019 Form 10-K. Assets and liabilities are assigned to a level within the fair value hierarchy based on the lowest level of significant input used to measure fair value. Assets and liabilities may change levels within the fair value hierarchy due to market conditions or other circumstances. Those transfers are recognized on the date of the event that prompted the transfer. There were no transfers of assets or liabilities required to be measured at fair value on a recurring basis between levels of the fair value hierarchy during the periods presented. Assets and Liabilities Required to be Measured and Reported at Fair Value on a Recurring Basis The following table provides the fair value for assets and liabilities required to be measured and reported at fair value on a recurring basis on the Unaudited Consolidated Balance Sheets by level in the fair value hierarchy. Recurring Fair Value Measurements at Reporting Date September 30, 2020 December 31, 2019 (Dollars in thousands) Level 1 Level 2 Level 3 Level 1 Level 2 Level 3 Assets: Available-for-sale investment securities: Obligations of: U.S. government sponsored agencies $ — $ 5,383 $ — $ — $ 8,209 $ — States and political subdivisions — 104,126 — — 114,104 — Residential mortgage-backed securities — 726,992 — — 791,009 — Commercial mortgage-backed securities — 10,568 — — 18,088 — Bank-issued trust preferred securities — 4,633 — — 4,691 — Total available-for-sale securities — 851,702 — — 936,101 — Equity investment securities (a) 97 209 — 123 198 — Derivative assets (b) — 30,651 — — 11,419 — Liabilities: Derivative liabilities (c) $ — $ 44,002 $ — $ — $ 15,116 $ — (a) Included in other investment securities on the Unaudited Consolidated Balance Sheets.

(c) Included in accrued expenses and other liabilities on the Unaudited Consolidated Balance Sheets. For additional information, see "Note 9 Derivative Financial Instruments" of the Notes to the Unaudited Consolidated Financial Statements. Available-for-Sale Investment Securities: The fair values used by Peoples are obtained from an independent pricing service and represent either quoted market prices for the identical securities (Level 1) or fair values determined by pricing models using a market approach that considers observable market data, such as interest rate volatility, LIBOR yield curves, credit spreads and prices from market makers and live trading systems (Level 2). Management reviews the valuation methodology and quality controls utilized by the pricing services in management's overall assessment of the reasonableness of the fair values provided, and challenges prices when management believes a material discrepancy in pricing exists. Equity Investment Securities: The fair values of Peoples' equity investment securities are obtained from q uoted prices in active exchange markets for identical assets or liabilities (Level 1) or quoted prices in less active markets (Level 2). Derivative Assets and Liabilities : Derivative assets and liabilities are recognized on the Unaudited Consolidated Balance Sheets at their fair value within other assets and accrued expenses and other liabilities, respectively. The fair value for derivative instruments is determined based on market prices, broker-dealer quotations on similar products, or other related input parameters (Level 2). Assets and Liabilities Required to be Measured and Reported at Fair Value on a Non-Recurring Basis The following table provides the fair value for each class of assets and liabilities required to be measured and reported at fair value on a non-recurring basis on the Unaudited Consolidated Balance Sheets by level in the fair value hierarchy. Non-Recurring Fair Value Measurements at Reporting Date September 30, 2020 December 31, 2019 (Dollars in thousands) Level 1 Level 2 Level 3 Level 1 Level 2 Level 3 Other real estate owned ("OREO") $ — $ — $ 293 $ — $ — $ 227 Other Real Estate Owned: OREO, included in "Other assets" on the Unaudited Consolidated Balance Sheets, is comprised primarily of commercial and residential real estate properties acquired by Peoples in satisfaction of a loan. OREO obtained in satisfaction of a loan is recorded at the lower of cost or estimated fair value, less estimated costs to sell the property. The carrying value of OREO is not re-measured to fair value on a recurring basis, but 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 (Level 3). Financial Instruments Not Required to be Measured or Reported at Fair Value The following table provides the carrying amount for each class of assets and liabilities and the fair value for certain financial instruments that are not required to be measured or reported at fair value on the Unaudited Consolidated Balance Sheets. Fair Value Measurements of Other Financial Instruments (Dollars in thousands) Fair Value Hierarchy Level September 30, 2020 December 31, 2019 Carrying Amount Fair Value Carrying Amount Fair Value Assets: Cash and cash equivalents 1 $ 161,251 $ 161,251 $ 115,193 $ 115,193 Held-to-maturity investment securities: Obligations of: States and political subdivisions 2 3,539 4,073 4,346 4,791 Residential mortgage-backed securities 2 26,926 27,879 21,494 21,569 Commercial mortgage-backed securities 2 5,678 6,134 5,907 6,181 Total held-to-maturity securities 36,143 38,086 31,747 32,541 Other investment securities: Federal Home Loan Bank ("FHLB") stock 2 25,022 25,022 27,235 27,235 Federal Reserve Bank ("FRB") stock 2 13,311 13,311 13,310 13,310 Nonqualified deferred compensation 2 1,711 1,711 1,499 1,499 Other investment securities 2 365 365 365 365 Other investment securities (a) 40,409 40,409 42,409 42,409 Net loans 3 3,413,957 3,486,317 2,851,969 3,147,190 Loans held for sale 2 7,420 8,796 6,499 6,553 Bank owned life insurance 3 71,127 71,127 69,722 69,722 Servicing rights (b)(c) 3 2,489 2,789 2,742 3,881 Liabilities: Deposits 2 $ 3,952,005 $ 3,853,468 $ 3,291,412 $ 3,292,950 Short-term borrowings 2 182,063 185,713 316,977 317,973 Long-term borrowings 2 111,386 116,741 83,123 82,701 (a) Other investment securities, as reported on the Unaudited Consolidated Balance Sheets, also includes equity investment securities at September 30, 2020 and December 31, 2019, which are reported in the Assets and Liabilities Required to be Measured and Reported at Fair Value on a Recurring Basis table above and not included in this table. (b) Included in other intangible assets on the Unaudited Consolidated Balance Sheets. Servicing rights are carried at the lower of cost or market value. (c) There were no write-downs of servicing rights during the third and second quarters of 2020. Peoples recognized a write-down on servicing rights of $182,000 during the first quarter of 2020 as the fair value of the servicing rights was less than the carrying value. For certain financial assets and liabilities, carrying value approximates fair value due to the nature of each financial instrument. These instruments include cash and cash equivalents, demand and other non-fixed-maturity deposits, and overnight borrowings. Peoples used the following methods and assumptions in estimating the fair value of the following financial instruments: Cash and Cash Equivalents: Cash and cash equivalents include cash on hand, balances due from other banks, interest-bearing deposits in other banks, federal funds sold and other short-term investments with original maturities of ninety days or less. The carrying amount for cash and due from banks is a reasonable estimate of fair value. (Level 1). Held-to-Maturity Investment Securities: The fair values used by Peoples are obtained from an independent pricing service and represent fair values determined by pricing models using a market approach that considers observable market data, such as interest rate volatility, LIBOR yield curves, credit spreads and prices from market makers and live trading systems (Level 2). Management reviews the valuation methodology and quality controls utilized by the pricing services in management's overall assessment of the reasonableness of the fair values provided, and challenges prices when management believes a material discrepancy in pricing exists. Other Investment Securities: Other investment securities are measured at their respective redemption values due to restrictions placed on their transferability (Level 2). Net Loans: The fair value of portfolio loans assumes sale of the notes to a third-party financial investor. Accordingly, this value is not necessarily the value to Peoples if the notes were held to maturity. Peoples considered interest rate, credit and market factors in estimating the fair value of loans (Level 3). Fair values for loans are estimated using a discounted cash flow methodology. The discount rates take into account interest rates currently being offered to customers for loans with similar terms, the credit risk associated with the loan and other market factors, including liquidity. Loans Held for Sale: Loans originated and intended to be sold in the secondary market, generally 1-4 family residential loans, are carried, in aggregate, at the lower of cost or estimated fair value. The use of a valuation model using quoted prices of similar instruments represents significant inputs in arriving at the fair value (Level 2). Bank Owned Life Insurance: Peoples' bank owned life insurance policies are recorded at their cash surrender value (Level 3). Peoples recognizes tax-exempt income from the periodic increases in the cash surrender value of these policies and from death benefits. Servicing Rights : The fair value of the servicing rights is determined by using a discounted cash flow model, which estimates the present value of the future net cash flows of the servicing portfolio based on various factors, such as servicing costs, expected prepayment speeds and discount rates (Level 3). Peoples recognized a write-down on servicing rights of $182,000 during the first quarter of 2020 as the fair value of the servicing rights was less than the carrying value. There were no similar write-downs during the third and second quarters of 2020. Deposits: The fair value of fixed maturity certificates of deposit ("CDs") is estimated using a discounted cash flow calculation based on current rates offered for deposits of similar remaining maturities (Level 2). Short-term Borrowings: The fair value of short-term borrowings is estimated using a discounted cash flow analysis based on rates currently available to Peoples for borrowings with similar terms (Level 2). Long-term Borrowings: The fair value of long-term borrowings is estimated using a discounted cash flow analysis based on rates currently available to Peoples for borrowings with similar terms (Level 2). Certain financial assets and financial liabilities that are not required to be measured or reported at fair value can be subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). These financial assets and liabilities include the following: customer relationships, the deposit base, and other information required to compute Peoples’ aggregate fair value that are not included in the above information. Accordingly, the above fair values are not intended to represent the aggregate fair value of Peoples.

The gross gains and losses realized by Peoples from sales of available-for-sale securities for the periods ended September 30 were as follows: Three Months Ended Nine Months Ended September 30, September 30, (Dollars in thousands) 2020 2019 2020 2019 Gross gains realized $ 2 $ 97 $ 386 $ 157 Gross losses realized — — 3 87 Net gain realized $ 2 $ 97 $ 383 $ 70 The cost of investment securities sold, and any resulting gain or loss, were based on the specific identification method and recognized as of the trade date.

At September 30, 2020, management concluded that no individual securities at an unrealized loss position required an allowance for credit losses. At September 30, 2020, Peoples did not have the intent to sell, nor was it more likely than not that Peoples would be required to sell, any of the securities with an unrealized loss prior to recovery. Further, the unrealized losses at both September 30, 2020 and December 31, 2019 were largely attributable to changes in market interest rates and spreads since the securities were purchased, and were not credit related losses. Accrued interest receivable is not included in investment securities balances, and is presented in the “Other assets” line of the Unaudited Consolidated Balance Sheets, with no recorded allowance for credit losses. Interest receivable on investment securities was $3.4 million at September 30, 2020 and $3.6 million at December 31, 2019. At September 30, 2020, approximately 99% of the mortgage-backed securities with a market value that had been at an unrealized loss position for twelve months or more were issued by U.S. government sponsored agencies. The remaining 1%, or two positions, consisted of privately issued mortgage-backed securities with all of the underlying mortgages originated prior to 2004. Neither of the two positions had a fair value of less than 90% of its book value. Management analyzed the underlying credit quality of these mortgage-backed securities and concluded the unrealized losses were primarily attributable to the floating rate nature of these investments and the low remaining number of loans underlying these securities. The unrealized losses with respect to the two bank-issued trust preferred securities that had been in an unrealized loss position for twelve months or more at September 30, 2020 were primarily attributable to the subordinated nature of the debt. The table below presents the amortized cost, fair value and total weighted-average yield of available-for-sale securities by contractual maturity at September 30, 2020.

There were no gross gains or gross losses realized by Peoples from sales of held-to-maturity securities for any of the three and nine months ended September 30, 2020 and 2019. Management evaluates held-to-maturity investment securities for an allowance for credit losses on a quarterly basis. The majority of Peoples' held-to-maturity investment securities are issued by U.S. government sponsored agencies. The remaining securities are obligations of state and political subdivisions. Peoples analyzed these securities using cumulative default rate averages for investment grade municipal securities and determined that the potential credit losses of the securities was $6,000. As a result, at September 30, 2020, Peoples recorded $6,000 of allowance for credit losses for held-to-maturity securities, compared to $7,000 at January 1, 2020. The following table presents a summary of held-to-maturity investment securities that had an unrealized loss: Less than 12 Months 12 Months or More Total (Dollars in thousands) Fair Unrealized Loss No. of Securities Fair Unrealized Loss No. of Securities Fair Unrealized Loss September 30, 2020 Residential mortgage-backed securities $ 637 $ 1 1 $ — $ — — $ 637 $ 1 Total $ 637 $ 1 1 $ — $ — — $ 637 $ 1 December 31, 2019 Residential mortgage-backed securities $ 7,731 $ 67 1 $ 890 $ 27 1 $ 8,621 $ 94 Commercial mortgage-backed securities 1,666 1 1 — — — 1,666 1 Total $ 9,397 $ 68 2 $ 890 $ 27 1 $ 10,287 $ 95 The table below presents the amortized cost, fair value and total weighted-average yield of held-to-maturity securities by contractual maturity at September 30, 2020.

These redemptions totaled $2.1 million during the third quarter of 2020, $4.5 million during the second quarter of 2020, and $700,000 during the first quarter of 2020. Peoples purchased no additional FHLB stock during the third and second quarters of 2020, and purchased $5.0 million of additional FHLB stock during the first quarter of 2020, as a result of the FHLB of Cincinnati's capital requirements on FHLB advances during the quarter. During the three and nine months ended September 30, 2020, Peoples recorded the change in the fair value of equity investment securities held at September 30, 2020, in other non-interest income, resulting in unrealized gain of $1,000 and unrealized loss of $15,000, respectively. During the three and nine months ended September 30, 2019, Peoples recorded the change in the fair value of equity investment securities held at September 30, 2019, in other non-interest income, resulting in an unrealized gain of $19,000 and $828,000, respectively. Net realized gains on sales of equity investment securities, included in other non-interest income during the first nine months of 2019, consisted of a realized gain of $787,000 related to the sale of restricted Class B Visa stock, which had been held at a carrying cost and fair value of zero due to the litigation liability associated with the stock. At September 30, 2020, Peoples' investment in equity investment securities was comprised largely of common stocks issued by various unrelated bank holding companies. There were no equity investment securities of a single issuer that exceeded 10% of Peoples' stockholders' equity. Pledged Securities Peoples has pledged available-for-sale investment securities and held-to-maturity investment securities to secure public and trust department deposits, and repurchase agreements in accordance with federal and state requirements. Peoples has also pledged available-for-sale investment securities and held-to-maturity securities to secure additional borrowing capacity at the FHLB and the FRB.

Receivables [Abstract]
Loans	Loans Peoples' loan portfolio consists of various types of loans originated primarily as a result of lending opportunities within Peoples' primary market areas of northeastern, central, southwestern and southeastern Ohio, central and eastern Kentucky and west central West Virginia. Peoples also originates insurance premium finance loans nationwide through its premium finance division. Acquired loans consist of loans purchased in 2012 or thereafter. Loans that were acquired and subsequently re-underwritten are reported as originated upon execution of such credit actions (for example, renewals and increases in lines of credit). The major classifications of loan balances (in each case, net of deferred fees and costs) excluding loans held for sale, were as follows: (Dollars in thousands) September 30, December 31, 2019 Construction $ 108,051 $ 88,518 Commercial real estate, other 913,239 833,238 Commercial and industrial 1,168,134 662,993 Residential real estate 589,449 661,476 Home equity lines of credit 121,935 132,704 Consumer, indirect 491,699 417,185 Consumer, direct 79,059 76,533 Deposit account overdrafts 519 878 Total loans, at amortized cost $ 3,472,085 $ 2,873,525 Commercial and industrial loan balances grew significantly compared to December 31, 2019. Peoples began participating as a Small Business Administration ("SBA") Paycheck Protection Program ("PPP") lender during the second quarter of 2020, and originated $488.9 million of PPP loans during the first nine months of 2020. At September 30, 2020, the PPP loans had an amortized cost of $460.4 million, and were included in commercial and industrial loan balances. Peoples recorded deferred loan origination fees related to the PPP loans, net of deferred loan origination costs, which totaled $11.6 million at September 30, 2020. During the third quarter of 2020, Peoples recorded amortization of net deferred loan origination fees of $1.9 million on PPP loans. The remaining net deferred loan origination fees will be amortized over the life of the respective loans, or until forgiven by the SBA, and will be recognized in net interest income. Accrued interest receivable is not included within the loan balances, but is presented in the “Other assets” line of the Unaudited Consolidated Balance Sheets, with no recorded allowance for credit losses. Interest receivable on loans was $10.2 million at September 30, 2020 and $9.1 million at December 31, 2019. Nonaccrual and Past Due Loans A loan is considered past due if any required principal and interest payments have not been received as of the date such payments were required to be made under the terms of the loan agreement. A loan may be placed on nonaccrual status regardless of whether or not such loan is considered past due. The amortized cost of loans on nonaccrual status and loans delinquent for 90 days or more and accruing were as follows: September 30, 2020 December 31, 2019 (Dollars in thousands) Nonaccrual (a)(b) Accruing Loans 90+ Days Past Due Nonaccrual (a) Accruing Loans 90+ Days Past Due (b) Construction $ 4 $ — $ 411 $ — Commercial real estate, other 9,534 80 6,801 907 Commercial and industrial 6,317 74 2,155 155 Residential real estate 8,508 2,548 6,361 2,677 Home equity lines of credit 919 27 1,165 108 Consumer, indirect 961 86 840 — Consumer, direct 193 — 48 85 Total loans, at amortized cost $ 26,436 $ 2,815 $ 17,781 $ 3,932 (a) There were $1.3 million of nonaccrual loans for which there was no allowance for credit losses as of September 30, 2020 and $3.1 million at December 31, 2019. (b) The new accounting for purchased credit deteriorated loans under ASU 2016-13 resulted in the movement of $3.9 million of loans from the 90+ days past due and accruing category to the nonaccrual category as of January 1, 2020. At December 31, 2019, these loans were presented as 90+ days past due and accruing. During the third quarter of 2020, nonaccrual loans increased compared to June 30, 2020, mostly due to a single commercial relationship of $1.8 million that was placed on nonaccrual. As of September 30, 2020, Peoples had made short-term modifications, such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment for current borrowers, which were insignificant. Under the CARES Act, borrowers that are considered current are those that are less than 30 days past due on their contractual payments at the time a modification program is implemented. As such, these modifications made under the CARES Act are not included in Peoples' nonaccrual or accruing loans 90+ days past due as of September 30, 2020. The new accounting for purchased credit deteriorated loans under ASU 2016-13 resulted in the movement of $3.9 million of loans from the 90+ days past due and accruing category to the nonaccrual category as of January 1, 2020. As of December 31, 2019, these loans were presented as 90+ days past due and accruing. Although they were not accruing contractual interest income, they were accreting income from the discount that was recognized due to acquisition accounting. The additional increase in nonaccrual loans at September 30, 2020, compared to December 31, 2019, was due to two commercial relationships aggregating $3.3 million and several smaller commercial relationships being placed on nonaccrual. The amount of interest income recognized on nonaccrual loans during the three and nine months ended September 30, 2020 was $377,000 and $1.2 million, respectively.

Delinquency trends remained stable, as 99.2% of Peoples' portfolio was considered “current” at September 30, 2020, compared to 98.6% at December 31, 2019. Pledged Loans Peoples has pledged certain loans secured by one-to-four family and multifamily residential mortgages, and home equity lines of credit under a blanket collateral agreement to secure borrowings from the FHLB. Peoples also has pledged commercial loans to secure borrowings with the FRB. Loans pledged are summarized as follows: (Dollars in thousands) September 30, 2020 December 31, 2019 Loans pledged to FHLB $ 742,023 $ 458,227 Loans pledged to FRB 188,354 172,693 During 2020, Peoples pledged additional collateral to the FHLB and FRB to secure potential funding needs in light of the COVID-19 pandemic, as well as to fund the PPP loan originations that occurred during the year. Credit Quality Indicators As discussed in "Note 1 Summary of Significant Accounting Policies" of the Notes to the Consolidated Financial Statements included in Peoples' 2019 Form 10-K, Peoples categorizes the majority of its loans into risk categories based upon an established risk grading matrix using a scale of 1 to 8. Loan grades are assigned at the time a new loan or lending commitment is extended by Peoples and may be changed at any time when circumstances warrant. Loans to borrowers with an aggregate unpaid principal balance in excess of $1.0 million are reviewed at least on an annual basis for possible credit deterioration. Loan relationships whose aggregate credit exposure to Peoples is equal to or less than $1.0 million are reviewed on an event driven basis. Triggers for review include knowledge of adverse events affecting the borrower's business, receipt of financial statements indicating deteriorating credit quality or other similar events. Adversely classified loans are reviewed on a quarterly basis. A description of the general characteristics of the risk grades used by Peoples is as follows: “Pass” (grades 1 through 4): Loans in this risk category involve borrowers of acceptable-to-strong credit quality and risk who have the apparent ability to satisfy their loan obligations. Loans in this risk grade would possess sufficient mitigating factors, such as adequate collateral or strong guarantors possessing the capacity to repay the loan if required, for any weakness that may exist. “Special Mention” (grade 5): Loans in this risk grade are the equivalent of the regulatory definition of “Other Assets Especially Mentioned.” Loans in this risk category possess some credit deficiency or potential weakness, which requires a high level of management attention. Potential weaknesses include declining trends in operating earnings and cash flows and/or reliance on a secondary source of repayment. If left uncorrected, these potential weaknesses may result in noticeable deterioration of the repayment prospects for the loan or in Peoples' credit position. “Substandard” (grade 6): Loans in this risk grade are inadequately protected by the borrower's current financial condition and payment capability or the collateral pledged, if any. Loans so classified have one or more well-defined weaknesses that jeopardize the orderly repayment of the loan. They are characterized by the distinct possibility that Peoples will sustain some loss if the deficiencies are not corrected. “Doubtful” (grade 7): Loans in this risk grade have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or orderly repayment in full, on the basis of current existing facts, conditions and values, highly questionable and improbable. Possibility of loss is extremely high, but because of certain important and reasonably specific factors that may work to the advantage and strengthening of the exposure, classification of the loan as an estimated loss is deferred until its more exact status may be determined. “Loss” (grade 8): Loans in this risk grade are considered to be non-collectible and of such little value that their continuance as bankable assets is not warranted. This does not mean a loan has absolutely no recovery value, but rather it is neither practical nor desirable to defer writing off the loan, even though partial recovery may be obtained in the future. Charge-offs against the allowance for credit losses are taken during the period in which the loan becomes uncollectible. Consequently, Peoples typically does not maintain a recorded investment in loans within this category. Consumer loans and other smaller-balance loans are evaluated and categorized as “substandard,” or “loss” based upon the regulatory definition of these classes and consistent with regulatory requirements. All other loans not evaluated individually, nor meeting the regulatory conditions to be categorized as described above, would be considered as being “pass" for disclosure purposes. The following table summarizes the risk category of loans within Peoples' loan portfolio based upon the most recent analysis performed at September 30, 2020: (Dollars in thousands) 2020 2019 2018 2017 2016 Prior Revolving Loans Revolving Loans Converted to Term Total Loans Construction Pass $ 25,197 $ 42,715 $ 2,958 $ 14,650 $ 1,146 $ 17,668 $ 446 $ 3,311 $ 104,780 Special mention — 1,378 475 — — 144 — 475 1,997 Substandard — — — 195 — 730 349 — 1,274 Total 25,197 44,093 3,433 14,845 1,146 18,542 795 3,786 108,051 Commercial real estate, other Pass 89,909 99,713 99,193 99,656 112,043 220,567 126,990 27,562 848,071 Special mention 61 4,822 1,118 3,809 5,102 7,206 2,025 182 24,143 Substandard — 1,547 822 2,854 1,973 31,972 1,857 47 41,025 Total 89,970 106,082 101,133 106,319 119,118 259,745 130,872 27,791 913,239 Commercial and industrial Pass 495,729 92,863 75,491 40,026 49,385 170,044 206,382 27,217 1,129,920 Special mention 755 1,712 3,448 123 269 1,397 13,367 51 21,071 Substandard 2,337 1,665 1,439 1,977 300 4,014 3,638 2,722 15,370 Doubtful — — — — — 1,773 — — 1,773 Total 498,821 96,240 80,378 42,126 49,954 177,228 223,387 29,990 1,168,134 Residential real estate Pass 29,893 44,275 27,806 32,183 45,532 306,390 86,801 227 572,880 Special mention — — — — — 1 — — 1 Substandard — — — — — 15,962 126 — 16,088 Doubtful — — — — — 297 — — 297 Loss — — — — — 183 — — 183 Total 29,893 44,275 27,806 32,183 45,532 322,833 86,927 227 589,449 Home equity lines of credit Pass 11,065 13,802 13,087 14,651 11,751 43,776 13,803 4,025 121,935 Total 11,065 13,802 13,087 14,651 11,751 43,776 13,803 4,025 121,935 Consumer, indirect Pass 169,220 102,067 80,906 45,867 20,583 15,417 57,639 — 491,699 Total 169,220 102,067 80,906 45,867 20,583 15,417 57,639 — 491,699 Consumer, direct Pass 25,239 18,257 12,834 5,427 3,249 5,256 8,797 — 79,059 Total 25,239 18,257 12,834 5,427 3,249 5,256 8,797 — 79,059 Deposit account overdrafts 519 — — — — — — — 519 Total loans, at amortized cost $ 849,924 $ 424,816 $ 319,577 $ 261,418 $ 251,333 $ 842,797 $ 522,220 $ 65,819 $ 3,472,085 During the third quarter of 2020, Peoples downgraded several relationships due to the COVID-19 pandemic. The COVID-related downgrades contributed to increases of $17.5 million of additional criticized loans and $9.3 million of additional classified loans compared to balances at June 30, 2020. At September 30, 2020, Peoples had a total of $1.8 million of loans secured by residential real estate mortgages that were in the process of foreclosure. Collateral Dependent Loans Peoples has certain loans for which repayment is dependent upon the operation or sale of collateral, as the borrower is experiencing financial difficulty. The underlying collateral can vary based upon the type of loan. The following provides more detail about the types of collateral that secure collateral dependent loans: • Commercial real estate loans can be secured by either owner occupied commercial real estate or non-owner occupied investment commercial real estate. Typically, owner occupied commercial real estate loans are secured by office buildings, warehouses, manufacturing facilities and other commercial and industrial properties occupied by operating companies. Non-owner occupied commercial real estate loans are generally secured by office buildings and complexes, retail facilities, multifamily complexes, land under development, industrial properties, as well as other commercial or industrial real estate. • Residential real estate loans are typically secured by first mortgages, and in some cases could be secured by a second mortgage. • Home equity lines of credit are generally secured by second mortgages on residential real estate property. • Consumer loans are generally secured by automobiles, motorcycles, recreational vehicles and other personal property. Some consumer loans are unsecured and have no underlying collateral.

In addition, the increase in collateral dependent consumer loans was driven by a change in the policy threshold for evaluation of individually impaired loans, which was previously $100,000 and on January 1, 2020 was changed to $250,000, thereby reducing the amount of loans considered collateral dependent which were no longer above the threshold.

Loans modified in a TDR that were fully paid down, charged-off or foreclosed upon by period end are not reported. On March 22, 2020, federal and state government banking regulators issued a joint statement, with which the FASB concurred as to the approach, regarding accounting for loan modifications for borrowers affected by COVID-19. In this guidance, short-term modifications, made on a good faith basis in response to COVID-19, to borrowers who were current prior to any relief, are not considered TDRs. This includes short-term modifications such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment which are insignificant. Under the guidance, borrowers that are considered current are those that are less than 30 days past due on their contractual payments at the time a modification program is implemented. In addition, modification or deferral programs mandated by the U.S. federal government or any state government related to COVID-19 are not in the scope of accounting for troubled debt restructurings, as defined in ASC 310-40. The following table presents those loans modified into a TDR during the year that subsequently defaulted (i.e., 90 days or more past due following a modification during the nine-month periods ended September 30: September 30, 2020 September 30, 2019 (Dollars in thousands) Number of Contracts Recorded Investment (1) Impact on the Allowance for Loan Losses Number of Contracts Recorded Investment (1) Impact on the Allowance for Loan Losses Commercial real estate, other 1 $ 54 — — $ — $ — Consumer, direct — — — 1 35 $ — Total 1 $ 54 $ — 1 $ 35 $ — (1) The amounts shown are inclusive of all partial paydowns and charge-offs.

Peoples increased its allowance for credit losses based on CECL model results, which incorporated economic forecasts at the end of September 2020. The primary drivers of the increase compared to June 30, 2020, were the recent developments related to COVID-10 and the resulting impact on the economic assumptions used in estimating the allowance for credit losses under the CECL model, the addition of a specific reserve of $1.9 million related to one commercial loan relationship impacted by COVID-19 and the $932,000 recorded to establish the allowance for credit losses related to the premium finance acquisition completed on July 1, 2020. The PPP loans originated during 2020 are guaranteed by the SBA, and therefore, had no impact on the allowance for credit losses at September 30, 2020. The significant increase in the allowance for credit losses as of September 30, 2020 compared to January 1, 2020 was mostly due to the recent COVID-19 pandemic, and the resulting impact on economic forecasts utilized in the CECL model. Peoples calculates its allowance for credit losses using a discounted cash flow model, and incorporates economic forecasts, including U.S. unemployment, Ohio unemployment, Ohio Gross Domestic Product, and the Ohio Case Shiller Home Price Indices as economic factors. The economic forecast used in the September 30, 2020 calculation of the allowance for credit losses included higher unemployment rates and lower Ohio Gross Domestic Product than those at January 1, 2020, which drove much of the increase in the allowance for credit losses at September 30, 2020. In addition, Peoples recorded an increase of $5.8 million in allowance for credit losses on January 1, 2020 related to the implementation of ASU 2016-13. As of September 30, 2020, the CECL model produced results, based on economic forecasts, which were higher than Peoples believed to be appropriate at the time. The majority of the modifications that were granted by Peoples early in the pandemic had expired by September 30, 2020, with the remaining requests considered minimal. Peoples' delinquency rates improved at September 30, 2020, compared to December 31, 2019. Peoples believes the actions taken to provide early relief to consumer and commercial customers, which included at least 90 days of payment relief for those customers, coupled with the CARES Act stimulus package and the SBA PPP, indicate that Peoples would not experience the projected credit losses produced by the model. Therefore, Peoples made certain qualitative adjustments to more closely reflect its estimate of the potential losses of its loan portfolio at September 30, 2020. During the second quarter of 2020, Peoples recognized a recovery of $750,000 on a commercial and industrial loan that was previously charged-off, and recognized a similar $1.2 million recovery during the first quarter of 2020. As of September 30, 2020, Peoples had recorded an unfunded commitment liability of $3.3 million, an increase compared to the $3.1 million at June 30, 2020, and the $1.5 million that was recorded on January 1, 2020. The increase in the unfunded commitment liability was mostly related to the higher unadvanced portions of commercial lines of credit, as the utilization rate by customers declined compared to prior periods. The unfunded commitment liability is presented in the “Accrued expenses and other liabilities” line of the Unaudited Consolidated Balance Sheets.

During the first nine months of 2020, Peoples entered into one additional $50.0 million FHLB putable, non-amortizing fixed-rate advance with an interest rate of 0.77%, which matures in 2030. Peoples also reclassified two long-term FHLB non-amortizing advances totaling $20.0 million to short-term borrowings as the maturity became less than one year. The FHLB putable, non-amortizing, fixed rate advances have maturities ranging f rom one may be repaid prior to maturity, subject to the payment of termination fees. The FHLB has the option, at its sole discretion, to terminate the advance after an initial fixed rate period of three months or twelve months, requiring full repayment of the advance by Peoples prior to the stated maturity. If an advance is terminated prior to maturity, the FHLB will offer Peoples replacement funding at the then-prevailing rate on an advance product then offered by the FHLB, subject to normal FHLB credit and collateral requirements. These advances require monthly interest payments, with no repayment of principal until the earlier of either an option to terminate being exercised by the FHLB or the stated maturity. The amortizing, fixed-rate FHLB advances have a fixed rate for the term of each advance, with remaining maturities ranging from five to ten years. These advances require monthly principal and interest payments, with some having a constant prepayment rate requiring an additional principal payment annually. These advances are not eligible for optional prepayment prior to maturity. At September 30, 2020, the aggregate minimum annual retirements of long-term borrowings in future periods are as follows: (Dollars in thousands) Balance Weighted-Average Rate (a) Three months ending December 31, 2020 $ 818 1.98 % Year ending December 31, 2021 1,979 1.53 % Year ending December 31, 2022 16,521 1.98 % Year ending December 31, 2023 1,157 1.49 % Year ending December 31, 2024 869 1.47 % Thereafter 90,042 1.54 % Total long-term borrowings $ 111,386 1.61 % (a) The weighted-average rate includes the impact of accreting the current book value of the junior subordinated debt securities to face value over the period.

An aggregate of $6.3 million of Peoples' common shares were purchased under the previous share repurchase program from inception through its termination date, which was February 27, 2020. During the first nine months of 2020, Peoples purchased an aggregate of $25.0 million of its outstanding common shares, $843,000 of which were purchased under the previous share repurchase program and $24.2 million of which were purchased under the share repurchase program authorized on February 27, 2020.

Retirement Benefits [Abstract]
Employee Benefit Plans	Employee Benefit Plans Peoples sponsors a noncontributory defined benefit pension plan that covers substantially all employees hired before January 1, 2010. The plan provides retirement benefits based on an employee’s years of service and compensation. For employees hired before January 1, 2003, the amount of postretirement benefit is based on the employee’s average monthly compensation over the highest five Peoples also provides post-retirement health and life insurance benefits to certain former employees and directors. Only those individuals who retired before January 27, 2012 were eligible for life insurance benefits. As of January 1, 2011, all retirees who desire to participate in the Peoples Bank medical plan do so by electing COBRA, which provides up to 18 months of coverage; retirees over the age of 65 also have the option to pay to participate in a group Medicare supplemental plan. Peoples only pays 100% of the cost for those individuals who retired before January 1, 1993. For all others, the retiree is responsible for most, if not all, of the cost of the health benefits. Peoples’ policy is to fund the cost of the benefits as they arise. The following tables detail the components of the net periodic cost for the plans described above: Pension Benefits Three Months Ended Nine Months Ended September 30, September 30, (Dollars in thousands) 2020 2019 2020 2019 Interest cost $ 80 $ 109 $ 256 $ 328 Expected return on plan assets (187) (195) (577) (586) Amortization of net loss 35 19 101 58 Settlement of benefit obligation 531 — 1,050 — Net periodic loss (income) $ 459 $ (67) $ 830 $ (200) Postretirement Benefits Three Months Ended Nine Months Ended September 30, September 30, (Dollars in thousands) 2020 2019 2020 2019 Interest cost $ 1 $ 1 $ 2 $ 3 Amortization of prior service cost — — — (1) Amortization of net gain (2) (2) (4) (4) Net periodic income $ (1) $ (1) $ (2) $ (2) Under US GAAP, Peoples is required to recognize a settlement gain or loss when the aggregate amount of lump-sum distributions to participants equals or exceeds the sum of the service and interest cost components of the net periodic pension cost. The amount of settlement gain or loss recognized is the pro rata amount of the unrealized gain or loss existing immediately prior to the settlement. In general, both the projected benefit obligation and fair value of plan assets are required to be remeasured in order to determine the settlement gain or loss. In the first nine months of 2020, the total lump-sum distributions made to participants under the noncontributory defined benefit pension plan caused the total settlements to exceed the recognition threshold for settlement gains or losses. As a result, Peoples recorded settlement charges of $531,000 and $1.1 million, respectively, in the three and nine months ended September 30, 2020. There were no settlement charges recorded during the three and nine months ended September 30, 2019 under the noncontributory defined benefit pension plan. The following table summarizes the change in the projected benefit obligation and funded status as a result of the remeasurement and the aggregate settlements for the nine months ended September 30, 2020: As of September 30, 2020 (Dollars in thousands) December 31, Before Impact of After Funded status: 2019 Settlements Settlements Settlements Projected benefit obligation $ 12,668 $ 12,854 $ (1,172) $ 11,682 Fair value of plan assets 11,865 10,989 (1,172) 9,817 Funded status $ (803) $ (1,865) $ — $ (1,865) Gross unrealized loss $ 5,068 $ 5,834 $ (531) $ 5,303 Assumptions: Discount rate 3.12 % 2.51 % 2.51 % Expected return on plan assets 7.50 % 7.50 % 7.50 %

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging [Text Block]	Derivative Financial Instruments Peoples utilizes interest rate swap agreements as part of its asset/liability management strategy to help manage its interest rate risk position. The notional amount of the interest rate swaps does not represent amounts 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. The fair value of derivative financial instruments is included in the other assets and the accrued expenses and other liabilities lines in the accompanying Unaudited Consolidated Balance Sheets and in the net cash provided by operating activities in the Unaudited Consolidated Statements of Cash Flows. Derivative Financial Instruments and Hedging Activities - Risk Management Objective of Using Derivative Financial Instruments Peoples is exposed to certain risks arising from both its business operations and economic conditions. Peoples principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. Peoples manages economic risks, including interest rate, liquidity and credit risk, primarily by managing the amount, sources and duration of its assets and liabilities, and through the use of derivative financial instruments. Specifically, Peoples enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known or expected cash amounts, the values of which are determined by interest rates. Peoples’ derivative financial instruments are used to manage differences in the amount, timing and duration of Peoples' known or expected cash receipts and its known or expected cash payments principally related to certain variable rate borrowings. Peoples also has interest rate derivative financial instruments that result from a service provided to certain qualifying customers and, therefore, are not used to manage interest rate risk in Peoples' assets or liabilities. Peoples manages a matched book with respect to customer-related derivative financial instruments in order to minimize its net risk exposure resulting from such transactions. Cash Flow Hedges of Interest Rate Risk Peoples' objectives in using interest rate derivative financial instruments are to add stability to interest income and expense, and to manage its exposure to interest rate movements. To accomplish these objectives, Peoples has entered into interest rate swaps as part of its interest rate risk management strategy. These interest rate swaps are designated as cash flow hedges and involve the receipt of variable rate amounts from a counterparty in exchange for Peoples making fixed payments. As of September 30, 2020, Peoples had entered into seventeen interest rate swap contracts with an aggregate notional value of $160.0 million. Peoples will pay a fixed rate of interest for up to ten years while receiving a floating rate component of interest equal to the three-month LIBOR rate. The interest received on the floating rate component is intended to offset the interest paid on rolling three-month FHLB advances or rolling three-month brokered CDs, which will continue to be rolled through the life of the swaps. As of September 30, 2020, the interest rate swaps were funded by $110.0 million of rolling three-month FHLB advances and $50.0 million of rolling three-month brokered deposits. Amounts reported in accumulated other comprehensive income (loss) ("AOCI") related to derivative financial instruments will be reclassified to interest income or expense as interest payments are made or received on Peoples' variable-rate assets or liabilities. During the three and nine months ended September 30, 2020, Peoples had reclassifications of losses to earnings of $732,000 and $1.2 million, respectively. During the three and nine months ended September 30, 2019, Peoples had reclassifications of gains to interest expense of $30,000 and $183,000, respectively. For derivative financial instruments designated as cash flow hedges, the effective portion of changes in the fair value of each derivative financial instrument is reported in AOCI (outside of earnings), net of tax, and subsequently reclassified to earnings when the hedged transaction affects earnings, and the ineffective portion of changes in the fair value of the derivative is recognized directly in earnings. Peoples assesses the effectiveness of each hedging relationship by comparing the changes in cash flows of the hedging derivative financial instrument with the changes in cash flows of the designated hedged transaction. The reset dates and the payment dates on the 90-day advances or brokered CDs used to fund the swaps are matched to the reset dates and payment dates on the receipt of the three-month LIBOR floating portion of the swaps to ensure effectiveness of the cash flow hedge. Effectiveness is measured by ensuring that reset dates and payment dates are matched. The following table summarizes information about the interest rate swaps designated as cash flow hedges: (Dollars in thousands) September 30, December 31, Notional amount $ 160,000 $ 160,000 Weighted average pay rates 2.18 % 2.18 % Weighted average receive rates 0.34 % 1.73 % Weighted average maturity 4.6 years 5.4 years Pre-tax unrealized losses included in AOCI $ (13,164) $ (3,503) The following table presents net losses or gains recorded in AOCI and in the Unaudited Consolidated Statements of Operations related to the cash flow hedges: Three Months Ended Nine Months Ended September 30, September 30, (Dollars in thousands) 2020 2019 2020 2019 Amount of (gain) loss recognized in AOCI, pre-tax $ (803) $ 1,857 $ 9,661 $ 6,824 Amount of loss recognized in earnings $ — $ — $ — $ (19) The following table reflects the cash flow hedges, which are included in the Unaudited Consolidated Balance Sheets at fair value: September 30, December 31, (Dollars in thousands) Notional Amount Fair Value Notional Amount Fair Value Included in "Other assets": Interest rate swaps related to debt $ — $ — $ 55,000 $ 644 Included in "Accrued expenses and other liabilities": Interest rate swaps related to debt $ 160,000 $ 13,350 $ 105,000 $ 4,340 Non-Designated Hedges Peoples maintains an interest rate protection program for commercial loan customers, which was established in 2010. Under this program, Peoples originates variable rate loans with interest rate swaps, where the customer enters into an interest rate swap with Peoples on terms that match the terms of the loan. By entering into the interest rate swap with the customer, Peoples Bank effectively provides the customer with a fixed rate loan while creating a variable rate asset for Peoples Bank. Peoples Bank offsets its exposure in the swap by entering into an offsetting interest rate swap with an unaffiliated institution. These interest rate swaps do not qualify as designated hedges; therefore, each swap is accounted for as a standalone derivative financial instrument. These interest rate swaps did not have a material impact on Peoples' results of operation or financial condition. The following table reflects the non-designated hedges, which are included in the Unaudited Consolidated Balance Sheets at fair value: September 30, December 31, (Dollars in thousands) Notional Amount Fair Value Notional Amount Fair Value Included in "Other assets": Interest rate swaps related to commercial loans $ 387,239 $ 30,651 $ 321,394 $ 10,776 Included in "Accrued expenses and other liabilities": Interest rate swaps related to commercial loans $ 387,239 $ 30,651 $ 321,394 $ 10,776 Pledged Collateral Peoples pledges collateral for all interest rate swaps. When the fair value of Peoples' interest rate swaps is in a net liability position, Peoples must pledge collateral, and, when the fair value of Peoples' interest rate swaps is in a net asset position, the counterparties must pledge collateral. At September 30, 2020 and December 31, 2019, Peoples had $46.9 million and $20.0 million, respectively, of cash pledged, while the counterparties had no amount of cash pledged at either date. Cash pledged is included in "interest-bearing deposits in other banks" on the Unaudited Consolidated Balance Sheets.

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation Under the Peoples Bancorp Inc. Third Amended and Restated 2006 Equity Plan (the "2006 Equity Plan"), Peoples may grant, among other awards, nonqualified stock options, incentive stock options, restricted common share awards, stock appreciation rights, performance units and unrestricted common share awards to employees and non-employee directors. The total number of common shares available under the 2006 Equity Plan is 891,340. The maximum number of common shares that can be issued for incentive stock options is 500,000 common shares. Since February 2009, Peoples has granted restricted common shares to employees, and periodically to non-employee directors, subject to the terms and conditions prescribed by the 2006 Equity Plan. Additionally, in 2019 and 2020, Peoples granted unrestricted common shares to non-employee directors (in addition to their directors' fees paid in common shares) and to full-time and part-time employees who did not already participate in the 2006 Equity Plan. In general, common shares issued in connection with stock-based awards are issued from treasury shares to the extent available. If no treasury shares are available, common shares are issued from authorized but unissued common shares. Restricted Common Shares Under the 2006 Equity Plan, Peoples may award restricted common shares to officers, key employees and non-employee directors. In general, the restrictions on the restricted common shares awarded to employees expire after periods ranging from one The following table summarizes the changes to Peoples’ restricted common shares for the nine months ended September 30, 2020: Time-Based Vesting Performance-Based Vesting Number of Common Shares Weighted-Average Grant Date Fair Value Number of Common Shares Weighted-Average Grant Date Fair Value Outstanding at January 1 32,230 $ 33.05 253,884 $ 33.29 Awarded 20,864 20.21 80,338 32.91 Released 5,250 32.76 56,827 32.42 Forfeited 7,286 31.85 6,159 33.09 Outstanding at September 30 40,558 $ 26.70 271,236 $ 33.36 For the nine months ended September 30, 2020, the total intrinsic value for restricted common shares released was $2.0 million compared to $1.8 million for the nine months ended September 30, 2019. Performance Unit Awards Under the 2006 Equity Plan, Peoples may grant performance unit awards to officers, key employees and non-employee directors. On July 26, 2017, Peoples granted a total of seven performance unit awards to individuals who were then serving as officers, with a maximum aggregate dollar amount of $1.3 million represented by the performance units subject to such awards and each performance unit representing $1.00. During 2019, one of the seven performance unit awards was forfeited as the individual to whom the performance unit award was granted left Peoples before meeting the minimum service requirement to retain the performance unit award. The performance unit awards granted covered the performance period beginning January 1, 2018 and ending on December 31, 2019, and were subject to two performance goals. Peoples achieved the first performance goal by exceeding its target cumulative two-year adjusted earnings per share. However, Peoples failed to achieve the second performance goal as its adjusted return on average assets for the measurement period ranked below the target percentile compared to its peer group. As a result, during the first quarter of 2020, the remaining six officers holding performance unit awards received an aggregate of 9,395 common shares at a fair market value of $29.26 per common share on the date the performance units were deemed vested, with a related expense of $275,000 that had been recognized over the vesting period. Stock-Based Compensation Peoples recognizes stock-based compensation, which is included as a component of Peoples’ salaries and employee benefit costs, for restricted and unrestricted common shares and performance unit awards, as well as purchases made by participants in the employee stock purchase plan. For restricted common shares, Peoples recognizes stock-based compensation based on the estimated fair value of the awards expected to vest on the grant date. The estimated fair value is then expensed over the vesting period, which is normally three years. For performance unit awards, Peoples recognized stock-based compensation over the performance period, based on the portion of the awards that was expected to vest based on the expected level of achievement of the two performance goals. Peoples also has an employee stock purchase plan whereby employees can purchase Peoples' common shares at a discount of 15%. The following table summarizes the amount of stock-based compensation expense and related tax benefit recognized for each period: Three Months Ended Nine Months Ended September 30, September 30, (Dollars in thousands) 2020 2019 2020 2019 Employee stock-based compensation expense: Stock grant expense $ 615 $ 888 $ 2,950 $ 2,944 Employee stock purchase plan expense 17 16 $ 47 $ 48 Performance unit expense (benefit) — 46 $ (12) $ 96 Total employee stock-based compensation expense 632 950 $ 2,985 $ 3,088 Non-employee director stock-based compensation expense 53 50 $ 288 $ 252 Total stock-based compensation expense 685 1,000 $ 3,273 $ 3,340 Recognized tax benefit (144) (210) (687) (701) Net stock-based compensation expense $ 541 $ 790 $ 2,586 $ 2,639 Restricted common shares were the primary form of stock-based compensation awards granted by Peoples in the nine months ended September 30, 2020 and 2019. The fair value of restricted common share awards on the grant date is the market price of Peoples' common shares on that date. Total unrecognized stock-based compensation expense related to unvested restricted common share awards was $3.0 million at September 30, 2020, which will be recognized over a weighted-average period of 1.8 years. On April 1, 2020, an aggregate of 18,952 unrestricted common shares were granted as a one-time special award to employees under the level of Vice President, with a related stock-based compensation expense of $396,000 being recognized.

Peoples records contract assets for income that has been recognized over a period of time for fulfillment of performance obligations, but has not yet been received related to electronic banking income and certain insurance income. This income typically relates to bonuses for which Peoples is eligible, but will not receive until a certain time in the future. Peoples records contract liabilities for payments received for commission income related to the sale of insurance policies, for which the performance obligations have not yet been fulfilled. The contract liabilities are recognized as income over time, during the period in which the performance obligations are fulfilled, which is over the insurance policy period. Peoples also records contract liabilities for bonuses received related to electronic banking income, for which income is recognized during the period in which the performance obligations are fulfilled. As of September 30, 2020, there were no material changes to Peoples' revenue contracts related to the COVID-19 pandemic, and there were no changes to the likelihood of collectability under the contracts.

Adjustments to acquisition date estimated fair values are recorded in the period in which each adjustment is determined and, as a result, previously recorded results may change. Peoples has recorded a preliminary customer relationship intangible of $4.2 million. Peoples expects to amortize the intangible ove r 10 y ears. Amortization for the third quarter of 2020 was $128,000. As of the acquisition date, Peoples estimated an allowance for credit losses of $932,000 for the acquired loans through the income statement, which was included in the provision for credit losses during the third quarter of 2020. Acquired loans are reported net of the unamortized fair value adjustment.

Leases [Abstract]
Lessee, Operating Leases [Text Block]	Leases Peoples leases certain banking facilities and equipment under various agreements with original terms providing for fixed monthly payments over periods generally ranging from two thirty Peoples elected certain practical expedients, in accordance with ASC 842. Peoples also made an accounting policy election to account for each separate lease component of a contract and its associated non-lease components as a single lease component for all leases subject to ASC 842.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	9 Months Ended

Accounting Policies [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements: From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board ("FASB") or other standard setting bodies that are adopted by Peoples as of the required effective dates. The following should be read in conjunction with "Note 1 Summary of Significant Accounting Policies" of the Notes to the Consolidated Financial Statements included in Peoples’ 2019 Form 10-K. Unless otherwise discussed, management believes the impact of any recently issued standards, including those issued but not yet effective, will not have a material impact on Peoples' financial statements taken as a whole. Accounting Standards Update ("ASU") 2020-04 - Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This guidance provides optional expedients and exceptions for applying US GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. This update is effective as of March 12, 2020 through December 31, 2022. Per the guidance, Peoples is continuing to evaluate the impact of ASU 2020-04 on Peoples' consolidated financial statements. ASU 2016-13 - Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This accounting guidance replaces the "incurred loss" model for recognizing credit losses with an "expected loss" model, referred to as the Current Expected Credit Loss ("CECL") model. Under the CECL model, Peoples is required to present certain financial assets carried at amortized cost, such as loans held-for-investment and held-to-maturity investment securities, at the net amount expected to be collected. ASU 2018-19 clarified that receivables arising from operating leases are not within the scope of Accounting Standards Codification ("ASC") 326-20, and should be accounted for according to ASC 842. The measurement of expected credit losses is to be based on information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The measurement is to take place at the time the financial asset is first added to the balance sheet and periodically thereafter. This differs significantly from the "incurred loss" model under previous US GAAP accounting guidance, which delayed recognition until it was probable a loss had been incurred. Peoples adopted ASU 2016-13 using the modified retrospective method for all financial assets measured at amortized cost on January 1, 2020. Reporting periods beginning after December 31, 2019 are presented as required by ASU 2016-13, while prior period amounts continue to be reported in accordance with previously applicable US GAAP requirements. Peoples is using the prospective transition approach for financial assets purchased with credit deterioration that were previously classified as purchased credit impaired assets and accounted for under ASC 310-30. As of January 1, 2020, Peoples recorded a one-time cumulative-effect adjustment to reduce retained earnings by $3.7 million, net of statutory corporate federal income taxes, an increase in allowance for credit losses of $5.8 million and an increase in unfunded commitment liability of $1.5 million. On January 1, 2020, the amortized cost basis of the purchased credit deteriorated assets was adjusted to reflect the addition of $2.6 million to establish the allowance for credit losses. The remaining interest-related discount is being accreted into interest income at the effective interest rate beginning on January 1, 2020. As of January 1, 2020, Peoples did not record an allowance for credit losses for available-for-sale investment securities, as all unrealized losses on these securities were deemed to be non-credit in nature, with no credit deterioration upon review by Peoples. Peoples recorded an allowance for credit losses for held-to-maturity securities of $7,000 as of January 1, 2020. The following table illustrates the impact on the allowance for credit losses from the adoption of ASU 2016-13: (Dollars in thousands) As Reported Under ASC 326 January 1, 2020 Pre-ASC 326 Adoption December 31, 2019 Impact of ASC 326 Adoption Assets: Loans, at amortized cost $ 2,876,147 $ 2,873,525 $ 2,622 Allowance for credit losses on loans: Construction 651 1,188 (537) Commercial real estate, other 8,549 6,560 1,989 Commercial and industrial 5,820 8,568 (2,748) Residential real estate 4,360 1,296 3,064 Home equity lines of credit 1,572 612 960 Consumer, indirect 5,389 2,942 2,447 Consumer, direct 890 296 594 Deposit account overdrafts 94 94 — Allowance for credit losses on loans 27,325 21,556 5,769 Liabilities: Allowance for credit losses for unfunded commitments $ 1,495 $ — $ 1,495 Investment Securities: Investment securities are recorded initially at cost, which includes premiums and discounts if purchased at other than par or face value. Peoples amortizes premiums and accretes discounts as an adjustment to interest income on a level yield basis. The cost of investment securities sold, excluding equity investment securities, and any resulting gain or loss, is based on the specific identification method and recognized as of the trade date. The cost of equity investment securities is based on the weighted-average method. Peoples determines the appropriate classification of investment securities at the time of purchase. Held-to-maturity securities are those securities that Peoples has the positive intent and ability to hold to maturity and are recorded at amortized cost. Available-for-sale securities are those securities that would be available to be sold in the future in response to Peoples' liquidity needs, changes in market interest rates, and asset-liability management strategies, among other considerations. Available-for-sale securities are reported at fair value, with unrealized gains and losses reported in total stockholders' equity as a separate component of accumulated other comprehensive income or loss, net of applicable deferred income taxes. Certain restricted equity investment securities that do not have readily determinable fair values and for which Peoples does not exercise significant influence, are carried at cost. These cost method securities are reported in other investment securities on the Unaudited Consolidated Balance Sheets and consist primarily of shares of the Federal Home Loan Bank of Cincinnati (the "FHLB") and the Federal Reserve Bank of Cleveland (the "FRB"). Peoples evaluates available-for-sale investment securities on a quarterly basis to determine how much, if any, allowance for credit losses is required. Peoples reviews available-for-sale investment securities at an unrealized loss position, with potential exposure to a credit event (which excludes U.S. government and U.S. government sponsored agency securities) to determine if the unrealized loss was credit-related. An allowance for credit losses is recorded to the extent that the unrealized losses are credit-related and likely to be permanent. Peoples evaluates held-to-maturity investment securities on a quarterly basis in determining an allowance for credit losses. Peoples has determined that the loss given default for U.S. government sponsored enterprise investment securities is zero, due to the fact that it is unlikely the ultimate guarantor (the U.S. government) would not perform on its implicit guarantee in the event of default. The remaining securities are included in the calculation of the allowance for credit losses for held-to-maturity investment securities.

Loans		Loans Peoples' loan portfolio consists of various types of loans originated primarily as a result of lending opportunities within Peoples' primary market areas of northeastern, central, southwestern and southeastern Ohio, central and eastern Kentucky and west central West Virginia. Peoples also originates insurance premium finance loans nationwide through its premium finance division. Acquired loans consist of loans purchased in 2012 or thereafter. Loans that were acquired and subsequently re-underwritten are reported as originated upon execution of such credit actions (for example, renewals and increases in lines of credit). The major classifications of loan balances (in each case, net of deferred fees and costs) excluding loans held for sale, were as follows: (Dollars in thousands) September 30, December 31, 2019 Construction $ 108,051 $ 88,518 Commercial real estate, other 913,239 833,238 Commercial and industrial 1,168,134 662,993 Residential real estate 589,449 661,476 Home equity lines of credit 121,935 132,704 Consumer, indirect 491,699 417,185 Consumer, direct 79,059 76,533 Deposit account overdrafts 519 878 Total loans, at amortized cost $ 3,472,085 $ 2,873,525 Commercial and industrial loan balances grew significantly compared to December 31, 2019. Peoples began participating as a Small Business Administration ("SBA") Paycheck Protection Program ("PPP") lender during the second quarter of 2020, and originated $488.9 million of PPP loans during the first nine months of 2020. At September 30, 2020, the PPP loans had an amortized cost of $460.4 million, and were included in commercial and industrial loan balances. Peoples recorded deferred loan origination fees related to the PPP loans, net of deferred loan origination costs, which totaled $11.6 million at September 30, 2020. During the third quarter of 2020, Peoples recorded amortization of net deferred loan origination fees of $1.9 million on PPP loans. The remaining net deferred loan origination fees will be amortized over the life of the respective loans, or until forgiven by the SBA, and will be recognized in net interest income. Accrued interest receivable is not included within the loan balances, but is presented in the “Other assets” line of the Unaudited Consolidated Balance Sheets, with no recorded allowance for credit losses. Interest receivable on loans was $10.2 million at September 30, 2020 and $9.1 million at December 31, 2019. Nonaccrual and Past Due Loans A loan is considered past due if any required principal and interest payments have not been received as of the date such payments were required to be made under the terms of the loan agreement. A loan may be placed on nonaccrual status regardless of whether or not such loan is considered past due. The amortized cost of loans on nonaccrual status and loans delinquent for 90 days or more and accruing were as follows: September 30, 2020 December 31, 2019 (Dollars in thousands) Nonaccrual (a)(b) Accruing Loans 90+ Days Past Due Nonaccrual (a) Accruing Loans 90+ Days Past Due (b) Construction $ 4 $ — $ 411 $ — Commercial real estate, other 9,534 80 6,801 907 Commercial and industrial 6,317 74 2,155 155 Residential real estate 8,508 2,548 6,361 2,677 Home equity lines of credit 919 27 1,165 108 Consumer, indirect 961 86 840 — Consumer, direct 193 — 48 85 Total loans, at amortized cost $ 26,436 $ 2,815 $ 17,781 $ 3,932 (a) There were $1.3 million of nonaccrual loans for which there was no allowance for credit losses as of September 30, 2020 and $3.1 million at December 31, 2019. (b) The new accounting for purchased credit deteriorated loans under ASU 2016-13 resulted in the movement of $3.9 million of loans from the 90+ days past due and accruing category to the nonaccrual category as of January 1, 2020. At December 31, 2019, these loans were presented as 90+ days past due and accruing. During the third quarter of 2020, nonaccrual loans increased compared to June 30, 2020, mostly due to a single commercial relationship of $1.8 million that was placed on nonaccrual. As of September 30, 2020, Peoples had made short-term modifications, such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment for current borrowers, which were insignificant. Under the CARES Act, borrowers that are considered current are those that are less than 30 days past due on their contractual payments at the time a modification program is implemented. As such, these modifications made under the CARES Act are not included in Peoples' nonaccrual or accruing loans 90+ days past due as of September 30, 2020. The new accounting for purchased credit deteriorated loans under ASU 2016-13 resulted in the movement of $3.9 million of loans from the 90+ days past due and accruing category to the nonaccrual category as of January 1, 2020. As of December 31, 2019, these loans were presented as 90+ days past due and accruing. Although they were not accruing contractual interest income, they were accreting income from the discount that was recognized due to acquisition accounting. The additional increase in nonaccrual loans at September 30, 2020, compared to December 31, 2019, was due to two commercial relationships aggregating $3.3 million and several smaller commercial relationships being placed on nonaccrual. The amount of interest income recognized on nonaccrual loans during the three and nine months ended September 30, 2020 was $377,000 and $1.2 million, respectively.

Delinquency trends remained stable, as 99.2% of Peoples' portfolio was considered “current” at September 30, 2020, compared to 98.6% at December 31, 2019. Pledged Loans Peoples has pledged certain loans secured by one-to-four family and multifamily residential mortgages, and home equity lines of credit under a blanket collateral agreement to secure borrowings from the FHLB. Peoples also has pledged commercial loans to secure borrowings with the FRB. Loans pledged are summarized as follows: (Dollars in thousands) September 30, 2020 December 31, 2019 Loans pledged to FHLB $ 742,023 $ 458,227 Loans pledged to FRB 188,354 172,693 During 2020, Peoples pledged additional collateral to the FHLB and FRB to secure potential funding needs in light of the COVID-19 pandemic, as well as to fund the PPP loan originations that occurred during the year. Credit Quality Indicators As discussed in "Note 1 Summary of Significant Accounting Policies" of the Notes to the Consolidated Financial Statements included in Peoples' 2019 Form 10-K, Peoples categorizes the majority of its loans into risk categories based upon an established risk grading matrix using a scale of 1 to 8. Loan grades are assigned at the time a new loan or lending commitment is extended by Peoples and may be changed at any time when circumstances warrant. Loans to borrowers with an aggregate unpaid principal balance in excess of $1.0 million are reviewed at least on an annual basis for possible credit deterioration. Loan relationships whose aggregate credit exposure to Peoples is equal to or less than $1.0 million are reviewed on an event driven basis. Triggers for review include knowledge of adverse events affecting the borrower's business, receipt of financial statements indicating deteriorating credit quality or other similar events. Adversely classified loans are reviewed on a quarterly basis. A description of the general characteristics of the risk grades used by Peoples is as follows: “Pass” (grades 1 through 4): Loans in this risk category involve borrowers of acceptable-to-strong credit quality and risk who have the apparent ability to satisfy their loan obligations. Loans in this risk grade would possess sufficient mitigating factors, such as adequate collateral or strong guarantors possessing the capacity to repay the loan if required, for any weakness that may exist. “Special Mention” (grade 5): Loans in this risk grade are the equivalent of the regulatory definition of “Other Assets Especially Mentioned.” Loans in this risk category possess some credit deficiency or potential weakness, which requires a high level of management attention. Potential weaknesses include declining trends in operating earnings and cash flows and/or reliance on a secondary source of repayment. If left uncorrected, these potential weaknesses may result in noticeable deterioration of the repayment prospects for the loan or in Peoples' credit position. “Substandard” (grade 6): Loans in this risk grade are inadequately protected by the borrower's current financial condition and payment capability or the collateral pledged, if any. Loans so classified have one or more well-defined weaknesses that jeopardize the orderly repayment of the loan. They are characterized by the distinct possibility that Peoples will sustain some loss if the deficiencies are not corrected. “Doubtful” (grade 7): Loans in this risk grade have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or orderly repayment in full, on the basis of current existing facts, conditions and values, highly questionable and improbable. Possibility of loss is extremely high, but because of certain important and reasonably specific factors that may work to the advantage and strengthening of the exposure, classification of the loan as an estimated loss is deferred until its more exact status may be determined. “Loss” (grade 8): Loans in this risk grade are considered to be non-collectible and of such little value that their continuance as bankable assets is not warranted. This does not mean a loan has absolutely no recovery value, but rather it is neither practical nor desirable to defer writing off the loan, even though partial recovery may be obtained in the future. Charge-offs against the allowance for credit losses are taken during the period in which the loan becomes uncollectible. Consequently, Peoples typically does not maintain a recorded investment in loans within this category. Consumer loans and other smaller-balance loans are evaluated and categorized as “substandard,” or “loss” based upon the regulatory definition of these classes and consistent with regulatory requirements. All other loans not evaluated individually, nor meeting the regulatory conditions to be categorized as described above, would be considered as being “pass" for disclosure purposes.

The COVID-related downgrades contributed to increases of $17.5 million of additional criticized loans and $9.3 million of additional classified loans compared to balances at June 30, 2020. At September 30, 2020, Peoples had a total of $1.8 million of loans secured by residential real estate mortgages that were in the process of foreclosure. Collateral Dependent Loans Peoples has certain loans for which repayment is dependent upon the operation or sale of collateral, as the borrower is experiencing financial difficulty. The underlying collateral can vary based upon the type of loan. The following provides more detail about the types of collateral that secure collateral dependent loans: • Commercial real estate loans can be secured by either owner occupied commercial real estate or non-owner occupied investment commercial real estate. Typically, owner occupied commercial real estate loans are secured by office buildings, warehouses, manufacturing facilities and other commercial and industrial properties occupied by operating companies. Non-owner occupied commercial real estate loans are generally secured by office buildings and complexes, retail facilities, multifamily complexes, land under development, industrial properties, as well as other commercial or industrial real estate. • Residential real estate loans are typically secured by first mortgages, and in some cases could be secured by a second mortgage. • Home equity lines of credit are generally secured by second mortgages on residential real estate property. • Consumer loans are generally secured by automobiles, motorcycles, recreational vehicles and other personal property. Some consumer loans are unsecured and have no underlying collateral. The following table details Peoples' amortized cost of collateral dependent loans: (Dollars in thousands) September 30, 2020 December 31, 2019 Commercial real estate, other $ 8,999 $ 6,818 Commercial and industrial 6,487 1,962 Residential real estate 1,971 1,847 Home equity lines of credit 406 681 Consumer, indirect — 713 Consumer, direct — 94 Total collateral dependent loans $ 17,863 $ 12,115 The increase in collateral dependent commercial and industrial loans at September 30, 2020 compared to December 31, 2019 was mostly due to one commercial relationship that became collateral dependent, coupled with some smaller relationships. In addition, the increase in collateral dependent consumer loans was driven by a change in the policy threshold for evaluation of individually impaired loans, which was previously $100,000 and on January 1, 2020 was changed to $250,000, thereby reducing the amount of loans considered collateral dependent which were no longer above the threshold.

Loans modified in a TDR that were fully paid down, charged-off or foreclosed upon by period end are not reported. On March 22, 2020, federal and state government banking regulators issued a joint statement, with which the FASB concurred as to the approach, regarding accounting for loan modifications for borrowers affected by COVID-19. In this guidance, short-term modifications, made on a good faith basis in response to COVID-19, to borrowers who were current prior to any relief, are not considered TDRs. This includes short-term modifications such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment which are insignificant. Under the guidance, borrowers that are considered current are those that are less than 30 days past due on their contractual payments at the time a modification program is implemented. In addition, modification or deferral programs mandated by the U.S. federal government or any state government related to COVID-19 are not in the scope of accounting for troubled debt restructurings, as defined in ASC 310-40. The following table presents those loans modified into a TDR during the year that subsequently defaulted (i.e., 90 days or more past due following a modification during the nine-month periods ended September 30: September 30, 2020 September 30, 2019 (Dollars in thousands) Number of Contracts Recorded Investment (1) Impact on the Allowance for Loan Losses Number of Contracts Recorded Investment (1) Impact on the Allowance for Loan Losses Commercial real estate, other 1 $ 54 — — $ — $ — Consumer, direct — — — 1 35 $ — Total 1 $ 54 $ — 1 $ 35 $ — (1) The amounts shown are inclusive of all partial paydowns and charge-offs.

Peoples increased its allowance for credit losses based on CECL model results, which incorporated economic forecasts at the end of September 2020. The primary drivers of the increase compared to June 30, 2020, were the recent developments related to COVID-10 and the resulting impact on the economic assumptions used in estimating the allowance for credit losses under the CECL model, the addition of a specific reserve of $1.9 million related to one commercial loan relationship impacted by COVID-19 and the $932,000 recorded to establish the allowance for credit losses related to the premium finance acquisition completed on July 1, 2020. The PPP loans originated during 2020 are guaranteed by the SBA, and therefore, had no impact on the allowance for credit losses at September 30, 2020. The significant increase in the allowance for credit losses as of September 30, 2020 compared to January 1, 2020 was mostly due to the recent COVID-19 pandemic, and the resulting impact on economic forecasts utilized in the CECL model. Peoples calculates its allowance for credit losses using a discounted cash flow model, and incorporates economic forecasts, including U.S. unemployment, Ohio unemployment, Ohio Gross Domestic Product, and the Ohio Case Shiller Home Price Indices as economic factors. The economic forecast used in the September 30, 2020 calculation of the allowance for credit losses included higher unemployment rates and lower Ohio Gross Domestic Product than those at January 1, 2020, which drove much of the increase in the allowance for credit losses at September 30, 2020. In addition, Peoples recorded an increase of $5.8 million in allowance for credit losses on January 1, 2020 related to the implementation of ASU 2016-13. As of September 30, 2020, the CECL model produced results, based on economic forecasts, which were higher than Peoples believed to be appropriate at the time. The majority of the modifications that were granted by Peoples early in the pandemic had expired by September 30, 2020, with the remaining requests considered minimal. Peoples' delinquency rates improved at September 30, 2020, compared to December 31, 2019. Peoples believes the actions taken to provide early relief to consumer and commercial customers, which included at least 90 days of payment relief for those customers, coupled with the CARES Act stimulus package and the SBA PPP, indicate that Peoples would not experience the projected credit losses produced by the model. Therefore, Peoples made certain qualitative adjustments to more closely reflect its estimate of the potential losses of its loan portfolio at September 30, 2020. During the second quarter of 2020, Peoples recognized a recovery of $750,000 on a commercial and industrial loan that was previously charged-off, and recognized a similar $1.2 million recovery during the first quarter of 2020. As of September 30, 2020, Peoples had recorded an unfunded commitment liability of $3.3 million, an increase compared to the $3.1 million at June 30, 2020, and the $1.5 million that was recorded on January 1, 2020. The increase in the unfunded commitment liability was mostly related to the higher unadvanced portions of commercial lines of credit, as the utilization rate by customers declined compared to prior periods. The unfunded commitment liability is presented in the “Accrued expenses and other liabilities” line of the Unaudited Consolidated Balance Sheets.
