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 March 31, 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. Peoples' insurance income includes performance-based insurance commissions that are recognized by Peoples when received, which typically occurs, for the most part, during the first quarter of each year. For the three months ended March 31, 2020 and 2019, the amount of performance-based insurance commissions recognized totaled $1.3 million and $1.4 million, respectively. 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") 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 costs 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 and accounted for under ASC 310-30. Peoples did not reassess whether purchased credit impaired assets met the criteria of purchased credit deteriorated assets as of the date of adoption. 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 were 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.

Fair Value of Financial Instrum

Fair Value of Financial Instruments	3 Months Ended

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.

(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 March 31, 2020 December 31, 2019 (Dollars in thousands) Level 1 Level 2 Level 3 Level 1 Level 2 Level 3 Other real estate owned ("OREO") $ — $ — $ 226 $ — $ — $ 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.

(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) 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 the 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. 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.

During each of the three months ended March 31, 2020 and 2019, Peoples realized no gross losses from sales of available-for-sale securities. The gross gains realized by Peoples from sales of available-for-sale securities for the periods ended March 31 were as follows: Three Months Ended March 31, (Dollars in thousands) 2020 2019 Gross gains realized $ 319 $ 30 Net gain realized $ 319 $ 30 The cost of investment securities sold, and any resulting gain, were based on the specific identification method and recognized as of the trade date.

At March 31, 2020, management concluded that no individual securities at an unrealized loss position required an allowance for credit losses. At March 31, 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 March 31, 2020 and March 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 $3.8 million at March 31, 2020 and $3.6 million at December 31, 2019. At March 31, 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. Both of these positions had a fair value of less than 90% of their book value, with an aggregate book and fair value of $202,000 and $165,000, respectively. Management analyzed the underlying credit quality of these 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 March 31, 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 March 31, 2020. The weighted-average yields are based on the amortized cost. In some cases, the issuers may have the right to call or prepay obligations without call or prepayment penalties prior to the contractual maturity date.

At March 31, 2020, there were no held-to-maturity investment securities that had an unrealized loss.

The majority of Peoples' held-to-maturity investment securities are issued by U.S. government sponsored agencies. The remaining securities were 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 March 31, 2020, Peoples recorded $6,000 of allowance for credit losses for held-to-maturity securities, compared to $7,000 at January 1, 2020. The table below presents the amortized cost, fair value and total weighted-average yield of held-to-maturity securities by contractual maturity at March 31, 2020. The weighted-average yields are based on the amortized cost and are computed on a fully taxable-equivalent basis using a statutory federal corporate income tax rate of 21%.

Peoples purchased additional FHLB Stock, which totaled $5.0 million during the first quarter 2020, as a result of the FHLB of Cincinnati's capital requirements on FHLB advances during the quarter. During the three months ended March 31, 2020 and March 31, 2019, Peoples recorded the change in the fair value of equity investment securities held at March 31, 2020 and March 31, 2019, respectively, in other non-interest income, resulting in unrealized loss of $30,000 and unrealized gain of $22,000, respectively. Net realized gains on sales of equity investment securities, included in other non-interest income during the first three 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 March 31, 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 had 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.

Receivables [Abstract]
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, west central West Virginia, and central and eastern Kentucky. 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) March 31, December 31, 2019 Construction $ 110,865 $ 88,518 Commercial real estate, other 897,817 833,238 Commercial and industrial 654,530 662,993 Residential real estate 625,366 661,476 Home equity lines of credit 128,011 132,704 Consumer, indirect 418,066 417,185 Consumer, direct 76,172 76,533 Deposit account overdrafts 610 878 Total loans, at amortized cost $ 2,911,437 $ 2,873,525 Accrued interest receivable is not included in loan 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 loans was $8.8 million at March 31, 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: March 31, 2020 December 31, 2019 (Dollars in thousands) Nonaccrual (1)(2) Accruing Loans 90+ Days Past Due Nonaccrual (1) Accruing Loans 90+ Days Past Due (2) Construction $ 99 $ — $ 411 $ — Commercial real estate, other 9,577 — 6,801 907 Commercial and industrial 5,010 806 2,155 155 Residential real estate 8,640 557 6,361 2,677 Home equity lines of credit 1,152 143 1,165 108 Consumer, indirect 834 — 840 — Consumer, direct 170 37 48 85 Total loans, at amortized cost $ 25,482 $ 1,543 $ 17,781 $ 3,932 (1) There were no nonaccrual loans for which there was no allowance for credit losses.

At December 31, 2019, these loans were presented as 90+ days past due and accruing, 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 compared to December 31, 2019 was due to a $1.5 million commercial relationship and several smaller commercial relationships being placed on nonaccrual. The amount of interest income recognized on nonaccrual loans during the first quarter of 2020 was $458,000.

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 of Cincinnati. Peoples also has pledged commercial loans to secure borrowings with the FRB of Cleveland. Loans pledged are summarized as follows: (Dollars in thousands) March 31, 2020 December 31, 2019 Loans pledged to FHLB of Cincinnati $ 484,772 $ 458,227 Loans pledged to FRB of Cleveland 440,349 172,693 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 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 generally 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,” “doubtful,” 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.

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) March 31, 2020 December 31, 2019 Commercial real estate, other $ 9,572 $ 6,818 Commercial and industrial 5,791 1,962 Residential real estate 2,006 1,847 Home equity lines of credit 776 681 Consumer, indirect — 713 Consumer, direct — 94 Total collateral dependent loans $ 18,145 $ 12,115 The increase in collateral dependent commercial and industrial loans at March 31, 2020 compared to December 31, 2019 was mostly due to one commercial relationship that became collateral dependent. In addition, the decline in collateral dependent consumer loans was driven by a change in the 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. The following table summarizes the loans that were modified as TDRs during the three months ended March 31: Recorded Investment (1) (Dollars in thousands) Number of Contracts Pre-Modification Post-Modification Remaining Recorded Investment March 31, 2020 Originated loans: Commercial real estate, other 1 $ 265 $ 265 $ 265 Commercial and industrial 1 145 145 145 Residential real estate 3 452 483 481 Home equity lines of credit 2 41 41 41 Consumer - indirect 11 175 175 175 Consumer - direct 4 57 57 57 Total 22 $ 1,135 $ 1,166 $ 1,164 March 31, 2019 Originated loans: Commercial and industrial 2 $ 38 $ 38 $ 36 Residential real estate 2 399 403 403 Home equity lines of credit 2 79 79 79 Consumer, indirect 6 72 72 72 Consumer, direct 5 37 37 37 Consumer 11 109 109 109 Total 17 $ 625 $ 629 $ 627 Acquired loans: Residential real estate 1 $ 24 $ 24 $ 24 Home equity lines of credit 2 65 66 66 Total 3 $ 89 $ 90 $ 90 (1) The amounts shown are inclusive of all partial paydowns and charge-offs. 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 with 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 ASC 310-40. Peoples did not have any loans that were modified as a TDR during the last twelve months that subsequently defaulted. Peoples had no commitments to lend additional funds to the related borrowers whose loan terms have been modified in a TDR. Allowance for Credit Losses Changes in the allowance for credit losses for the three months ended March 31, 2020: (Dollars in thousands) Beginning Balance, Initial Allowance for Purchased Credit Deteriorated Assets Provision for Credit Losses Charge-offs Recoveries Ending Balance, March 31, 2020 Construction $ 600 $ 51 $ 1,091 $ — $ — $ 1,742 Commercial real estate, other 7,193 1,356 3,487 (10) 116 12,142 Commercial and industrial 4,960 860 2,656 (937) 1,204 8,743 Residential real estate 3,977 383 1,445 (118) 57 5,744 Home equity lines of credit 1,570 2 136 (14) 1 1,695 Consumer, indirect 5,389 — 6,085 (721) 125 10,878 Consumer, direct 856 34 961 (62) 14 1,803 Deposit account overdrafts 94 — 145 (213) 60 86 Total $ 24,639 $ 2,686 $ 16,006 $ (2,075) $ 1,577 $ 42,833 The significant increase in the allowance for credit losses as of March 31, 2020 compared to January 1, 2020 was mostly due to the recent COVID-19 pandemic, and the resulting impact to 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 March 31, 2020 calculation of the allowance for credit losses included higher unemployment rates and lower Ohio Gross Domestic Product, which drove much of the increase in the allowance for credit losses at March 31, 2020. Approximately 72% of the increase in the allowance for credit losses at March 31, 2020, compared to January 1, 2020, was related to the change in the economic forecast, and the remaining increase was attributable to changes in the composition of the loan portfolio. 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 March 31, 2020, the CECL model produced results, based on economic forecasts, that were higher than Peoples believed to be appropriate at the time. Peoples believes the actions taken to provide relief to consumer and commercial customers, which include at least 90 days of payment relief for those customers, coupled with the Coronavirus Aid, Relief and Economic Security ("CARES") Act stimulus package and the Small Business Administration ("SBA") Paycheck Protection Program ("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 March 31, 2020. During the first quarter of 2020, Peoples recognized a recovery of $1.2 million on a commercial and industrial loan that was previously charged-off. As of March 31, 2020, Peoples had recorded an unfunded commitment liability of $2.4 million, an increase compared to $1.5 million on January 1, 2020. The unfunded commitment liability is presented in the “Accrued expenses and other liabilities” line of the Unaudited Consolidated Balance Sheets.

During the first three 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. 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 six to eleven 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.

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 March 31, (Dollars in thousands) 2020 2019 Interest cost $ 94 $ 109 Expected return on plan assets (200) (195) Amortization of net loss 30 19 Settlement of benefit obligation 368 — Net periodic loss (income) $ 292 $ (67) Postretirement Benefits Three Months Ended March 31, (Dollars in thousands) 2020 2019 Interest cost $ 1 $ 1 Amortization of net gain (2) (2) Net periodic income $ (1) $ (1) 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.

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 March 31, 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 certificates of deposit, which will continue to be rolled through the life of the swaps. As of March 31, 2020, the interest rate swaps were funded by $110.0 million of rolling three-month FHLB advances and $50.0 million rolling three-month brokered CDs. 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 months ended March 31, 2020, Peoples had reclassifications of gains to interest expense of $118,000 and during the three months ended March 31, 2019, Peoples had reclassifications of loss to earnings of $83,000. 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 certificates of deposit 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) March 31, December 31, Notional amount $ 160,000 $ 160,000 Weighted average pay rates 2.18 % 2.18 % Weighted average receive rates 0.58 % 1.73 % Weighted average maturity 5.1 years 5.4 years Pre-tax unrealized losses included in AOCI $ (13,233) $ (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 March 31, (Dollars in thousands) 2020 2019 Amount of loss recognized in AOCI, pre-tax $ (9,730) $ (1,833) 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: March 31, 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 Total included in other assets $ — $ — $ 55,000 $ 644 Included in accrued expenses and other liabilities: Interest rate swaps related to debt $ 160,000 $ 13,424 $ 105,000 $ 4,340 Total included in accrued expenses and other liabilities $ 160,000 $ 13,424 $ 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: March 31, December 31, (Dollars in thousands) Notional Amount Fair Value Notional Amount Fair Value Included in other assets: Interest rate swaps related to commercial loans $ 337,265 $ 30,235 $ 321,394 $ 10,776 Total included in other assets $ 337,265 $ 30,235 $ 321,394 $ 10,776 Included in accrued expenses and other liabilities: Interest rate swaps related to commercial loans $ 337,265 $ 30,235 $ 321,394 $ 10,776 Total included in accrued expenses and other liabilities $ 337,265 $ 30,235 $ 321,394 $ 10,776 Pledged Collateral When the fair value of Peoples' interest rate swaps are in a net liability position, Peoples must pledge collateral and when the interest rate swaps are in a net asset position, the counterparties must pledge collateral. At March 31, 2020 and December 31, 2019, Peoples had $44.0 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 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 three months ended March 31, 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 — — 80,338 32.91 Released 4,000 31.63 56,827 32.42 Forfeited 200 34.14 3,402 33.04 Outstanding at March 31 28,030 $ 33.25 273,993 $ 33.36 For the three months ended March 31, 2020, the total intrinsic value for restricted common shares released was $2.0 million compared to $1.1 million for the three months ended March 31, 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. Stock-Based Compensation Peoples recognizes stock-based compensation, which is included as a component of Peoples’ salaries and employee benefit costs, for restricted 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 March 31, (Dollars in thousands) 2020 2019 Employee stock-based compensation expense: Stock grant expense $ 1,380 $ 1,153 Employee stock purchase plan expense 15 16 Performance unit (benefit) expense (12) 39 Total employee stock-based compensation expense 1,383 1,208 Non-employee director stock-based compensation expense 182 152 Total stock-based compensation expense 1,565 1,360 Recognized tax benefit (329) (286) Net stock-based compensation expense $ 1,236 $ 1,074 Restricted common shares were the primary form of stock-based compensation awards granted by Peoples in the three months ended March 31, 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 $3.9 million at March 31, 2020, which will be recognized over a weighted-average period of 2.1 years.

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. 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.

Acquisitions [Abstract]
Business Combination Disclosure [Text Block]	Acquisitions On January 1, 2020, Peoples Insurance acquired a property and casualty-focused independent insurance agency for a purchase price amount equal to $866,000, and recorded $735,000 of customer relationship intangibles, and $27,000 of other assets, resulting in $104,000 of goodwill. The acquisition will not materially impact Peoples' financial position, results of operations or cash flows. As of March 31, 2020, Peoples had $319,000 of contingent consideration payable related to the acquisition. On April 20, 2020, Peoples signed an asset purchase agreement under which Peoples Bank will acquire the operations and assets of Triumph Premium Finance (“TPF”), a division of TBK Bank, SSB. Based in Kansas City, Missouri, TPF provides premium finance services for customers to purchase property and casualty insurance products through its network of independent insurance agency customers nationwide. Closing is expected to occur during the third quarter of 2020 and is subject to regulatory approval and other conditions set forth in the asset purchase agreement.

Lessee, Operating Leases [Text Block]	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. The table below details Peoples' lease expense, which is included in net occupancy and equipment expense in the Unaudited Consolidated Statements of Operations: Three Months Ended (Dollars in thousands) March 31, 2020 March 31, 2019 Operating lease expense $ 334 $ 307 Short-term lease expense 76 30 Total lease expense $ 410 $ 337 Peoples utilizes an incremental borrowing rate to determine the present value of lease payments for each lease, as the lease agreements do not provide an implicit rate. The estimated incremental borrowing rate reflects a secured rate and is based on the term of the lease and the interest rate environment at the lease commencement or remeasurement date.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	3 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") 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 costs 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 and accounted for under ASC 310-30. Peoples did not reassess whether purchased credit impaired assets met the criteria of purchased credit deteriorated assets as of the date of adoption. 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 were 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.
