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, 2018 (“Peoples' 2018 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’ 2018 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, 2019 for potential recognition or disclosure in these consolidated financial statements. In the opinion of management, these 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, 2018 , contained herein, has been derived from the audited Consolidated Balance Sheet included in Peoples’ 2018 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, 2019 and 2018 , the amount of performance-based insurance commissions recognized totaled $1.4 million and $1.3 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 accounting pronouncements should be read in conjunction with Note 1 Summary of Significant Accounting Policies of the Notes to the Consolidated Financial Statements included in Peoples’ 2018 Form 10-K. Accounting Standards Update ("ASU") 2017-04 - Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The amendments in this ASU simplify how an entity is required to test goodwill for impairment by eliminating the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge. This accounting guidance will be effective for interim and annual reporting periods beginning after December 15, 2019 (effective January 1, 2020 for Peoples). Peoples early adopted this new accounting guidance as of January 1, 2019, and it will be incorporated in the October 1, 2019 annual goodwill and intangible assets impairment analysis, but it is not expected to have a material impact 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 current "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 will be required to present certain financial assets carried at amortized cost, such as loans held-for-investment and held-to-maturity debt 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 Subtopic 326-20, and should be accounted for according to Topic 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. This measurement will 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 required under current US GAAP, which delays recognition until it is probable a loss has been incurred. Accordingly, Peoples expects that the adoption of the CECL model will materially affect how the allowance for loan losses is determined and could require significant increases to the allowance for loan losses. Moreover, the CECL model may create more volatility in the level of Peoples' allowance for loan losses. If required to materially increase the level of allowance for loan losses for any reason, such increase could adversely affect Peoples' business, financial condition and results of operations. The new CECL standard will become effective for interim and annual reporting periods beginning after December 15, 2019 (effective January 1, 2020 for Peoples). Peoples has a committee that meets regularly to monitor progress and oversee the project. Peoples has implemented a third-party software solution, and is utilizing the tool to run test calculations throughout 2019 in anticipation of the full implementation at the beginning of 2020. Peoples will complete model validation during 2019, and is currently refining the economic forecasting process, documenting accounting policies, reviewing business processes and evaluating potential changes to the control environment. Peoples is presently evaluating the impact that the CECL model will have on Peoples' financial statements and expects to recognize a one-time cumulative-effect adjustment to the allowance for loan loss provision as of the beginning of the first reporting period in which the new standard is effective, consistent with regulatory expectations set forth in interagency guidance issued at the end of 2016. The impact of the adoption will depend on relevant data at the adoption date, including the characteristics of the loan portfolio, macroeconomic conditions and forecasts. Peoples has not yet determined the magnitude of any such one-time cumulative-effect adjustment or of the overall impact of the new standard on Peoples' financial condition or results of operations.

Fair Value of Financial Instrum

Fair Value of Financial Instruments	3 Months Ended
	Mar. 31, 2019
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' 2018 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 Consolidated Balance Sheets by level in the fair value hierarchy. Recurring Fair Value Measurements at Reporting Date March 31, 2019 December 31, 2018 (Dollars in thousands) Level 1 Level 2 Level 3 Level 1 Level 2 Level 3 Assets: Available-for-sale investment securities: Obligations of: States and political subdivisions $ — $ 84,827 $ — $ — $ 88,587 $ — Residential mortgage-backed securities — 706,976 — — 692,608 — Commercial mortgage-backed securities — 6,649 — — 6,707 — Bank-issued trust preferred securities — 4,118 — — 3,989 — Total available-for-sale securities — 802,570 — — 791,891 — Equity investment securities 109 190 — 94 183 — Derivative assets (a) — 5,521 — — 4,544 — Liabilities: Derivative liabilities (b) $ — $ 6,404 $ — $ — $ 3,562 $ — (a) Included in Other assets on the Consolidated Balance Sheets. For additional information, see Note 9 Derivative Financial Instruments of the Notes to the Unaudited Consolidated Financial Statements. (b) Included in Other liabilities on the 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 Consolidated Balance Sheets at their fair value within other assets/liabilities. 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, 2019 December 31, 2018 (Dollars in thousands) Level 1 Level 2 Level 3 Level 1 Level 2 Level 3 Impaired loans $ — $ — $ 27,200 $ — $ — $ 24,129 Other real estate owned ("OREO") — — 81 — — 94 Impaired Loans: Impaired loans are measured and reported at fair value when the amounts to be received are less than the carrying value of the loans. One of the allowable methods for determining the amount of impairment is estimating fair value using the fair value of the collateral for collateral-dependent loans. Management’s determination of the fair value for these loans uses a market approach representing the estimated net proceeds to be received from the sale of the collateral based on observable market prices or the market value provided by independent, licensed or certified appraisers (Level 3), less estimated selling costs. At March 31, 2019 , impaired loans with an aggregate principal balance of $33.2 million were outstanding and reported at fair value of $27.2 million . For the three months ended March 31, 2019 , Peoples recognized an increase of $752,000 in the specific reserve on impaired loans, through the allowance for loan losses. Other Real Estate Owned ("OREO"): OREO, included in other assets on the 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).

(b) Included in other intangible assets on the Consolidated Balance Sheets. Servicing rights are carried at the lower of cost or market 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-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 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. Other Investment Securities: Other investment securities are measured at their respective redemption values (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 one-to-four 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 are 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). 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 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, deposit base, banking center networks, 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 gross losses 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) 2019 2018 Gross gains realized $ 30 $ 2 Gross losses realized — 1 Net gain realized $ 30 $ 1 The cost of investment securities sold, and any resulting gain or loss, was based on the specific identification method and recognized as of the trade date.

At March 31, 2019 , management concluded no individual securities were other-than-temporarily impaired since 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, 2019 and December 31, 2018 were largely attributable to changes in market interest rates and spreads since the securities were purchased. At March 31, 2019 , 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 $214,000 and $146,000 , 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 number of loans remaining in 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, 2019 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, 2019 . 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.

During the three months ended March 31, 2019, Peoples recorded the change in the fair value of equity investment securities held at March 31, 2019 in other non-interest income, resulting in unrealized gains of $22,000. During the three months ended March 31, 2018, Peoples recorded the change in the fair value of equity investment securities held at March 31, 2018 in other non-interest income, resulting in unrealized losses of $460,000. 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 $0 due to the litigation liability associated with the stock. At March 31, 2019 , 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 with carrying values of $500.8 million and $430.0 million at March 31, 2019 and December 31, 2018 , respectively, and held-to-maturity investment securities with carrying values of $16.2 million and $16.9 million at March 31, 2019 and December 31, 2018 , respectively, to secure public and trust department deposits, and repurchase agreements in accordance with federal and state requirements. Peoples also pledged available-for-sale investment securities with carrying values of $58.0 million and $60.1 million at March 31, 2019 and December 31, 2018 , respectively, and held-to-maturity securities with carrying values of $16.1 million and $16.7 million at March 31, 2019 and December 31, 2018 , respectively, 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, west central West Virginia, 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, 2018 Originated loans: Commercial real estate, construction $ 116,992 $ 124,013 Commercial real estate, other 630,679 632,200 Commercial real estate 747,671 756,213 Commercial and industrial 558,070 530,207 Residential real estate 297,667 296,860 Home equity lines of credit 90,831 93,326 Consumer, indirect 410,172 407,167 Consumer, direct 69,710 71,674 Consumer 479,882 478,841 Deposit account overdrafts 518 583 Total originated loans $ 2,174,639 $ 2,156,030 Acquired loans: Commercial real estate, construction $ 7,966 $ 12,404 Commercial real estate, other 171,785 184,711 Commercial real estate 179,751 197,115 Commercial and industrial 34,837 35,537 Residential real estate 308,137 296,937 Home equity lines of credit 38,084 40,653 Consumer, indirect 111 136 Consumer, direct 2,021 2,370 Consumer 2,132 2,506 Total acquired loans $ 562,941 $ 572,748 Loans, net of deferred fees and costs $ 2,737,580 $ 2,728,778 Peoples has acquired various loans through business combinations for which there was, at acquisition, evidence of deterioration of credit quality since origination, and for which it was probable that all contractually required payments would not be collected. The carrying amounts of these purchased credit impaired loans included in the loan balances above are summarized as follows: (Dollars in thousands) March 31, December 31, Commercial real estate $ 11,076 $ 11,955 Commercial and industrial 1,251 1,287 Residential real estate 19,275 20,062 Consumer 57 58 Total outstanding balance $ 31,659 $ 33,362 Net carrying amount $ 20,884 $ 22,475 Changes in the accretable yield for purchased credit impaired loans for the three months ended March 31 were as follows: (Dollars in thousands) March 31, March 31, Balance, beginning of period $ 8,955 $ 6,704 Accretion (484 ) (412 ) Balance, March 31 $ 8,471 $ 6,292 Peoples completes annual re-estimations of cash flows on acquired purchased credit impaired loans in August of each year. At the end of each quarter, Peoples evaluates factors to determine if a material change has occurred in acquired loans accounted for and if a re-estimation is needed. Factors evaluated to determine if a re-estimation is needed include changes in: risk ratings, maturity dates, charge-offs, payoffs, nonaccrual status and loans that have become past due. Prepayments affect the estimated life of the loans and could change the amount of interest income, and possibly the amount of principal, expected to be collected. In reforecasting future estimated cash flows, credit loss expectations are adjusted as necessary. Peoples evaluates changes quarterly and compares the new estimated cash flows to those at the previous cash flow re-estimation date and the related materiality of the changes, and when compared to the total loan portfolio, the differences in estimated cash flows at the most recent cash flow re-estimation date compared to the previous cash flow re-estimation date would not have a material impact on amounts recorded since the last re-estimation. Peoples completed a re-estimation of cash flows on purchased credit impaired loans in August 2018. Cash flows expected to be collected on purchased credit impaired loans are estimated by incorporating several key assumptions, similar to the initial estimate of fair value. These key assumptions include probability of default and the amount of actual prepayments after the acquisition date. Prepayments affect the estimated life of the loans and could change the amount of interest income and possibly the principal expected to be collected. In re-forecasting future estimated cash flows, credit loss expectations are adjusted as necessary. Pledged Loans Peoples pledges certain loans secured by 1-4 family and multifamily residential mortgages under a blanket collateral agreement to secure borrowings from the FHLB of Cincinnati. The amount of loans pledged under this blanket collateral agreement totaled $500.3 million and $505.7 million at March 31, 2019 and December 31, 2018 , respectively. Peoples also pledges commercial loans to secure borrowings with the FRB of Cleveland. The outstanding balances of these loans totaled $182.5 million and $180.9 million at March 31, 2019 and December 31, 2018 , respectively. 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 recorded investments in loans on nonaccrual status and loans delinquent for 90 days or more and accruing were as follows: Nonaccrual Loans Loans 90+ Days Past Due and Accruing (Dollars in thousands) March 31, December 31, March 31, December 31, Originated loans: Commercial real estate, construction $ 703 $ 710 $ — $ — Commercial real estate, other 6,273 6,565 — 786 Commercial real estate 6,976 7,275 — 786 Commercial and industrial 2,015 1,673 — — Residential real estate 4,098 4,105 239 398 Home equity lines of credit 520 596 42 7 Consumer, indirect 599 480 4 — Consumer, direct 22 56 — — Consumer 621 536 4 — Total originated loans $ 14,230 $ 14,185 $ 285 $ 1,191 Acquired loans: Commercial real estate, other $ 313 $ 319 $ 15 $ 15 Commercial and industrial 36 36 50 18 Residential real estate 1,770 1,921 724 1,032 Home equity lines of credit 740 637 — — Total acquired loans $ 2,859 $ 2,913 $ 789 $ 1,065 Total loans $ 17,089 $ 17,098 $ 1,074 $ 2,256 The following table presents the aging of the recorded investment in past due loans: Loans Past Due Current Loans Total Loans (Dollars in thousands) 30 - 59 days 60 - 89 days 90 + Days Total March 31, 2019 Originated loans: Commercial real estate, construction $ — $ — $ 703 $ 703 $ 116,289 $ 116,992 Commercial real estate, other 466 149 6,066 6,681 623,998 630,679 Commercial real estate 466 149 6,769 7,384 740,287 747,671 Commercial and industrial 1,641 4,228 1,118 6,987 551,083 558,070 Residential real estate 3,339 1,074 2,347 6,760 290,907 297,667 Home equity lines of credit 406 123 428 957 89,874 90,831 Consumer, indirect 2,291 189 216 2,696 407,476 410,172 Consumer, direct 204 24 5 233 69,477 69,710 Consumer 2,495 213 221 2,929 476,953 479,882 Deposit account overdrafts — — — — 518 518 Total originated loans $ 8,347 $ 5,787 $ 10,883 $ 25,017 $ 2,149,622 $ 2,174,639 Acquired loans: Commercial real estate, construction $ 503 $ 330 $ — $ 833 $ 7,133 $ 7,966 Commercial real estate, other 2,130 5 233 2,368 169,417 171,785 Commercial real estate 2,633 335 233 3,201 176,550 179,751 Commercial and industrial 309 96 86 491 34,346 34,837 Residential real estate 6,451 680 1,586 8,717 299,420 308,137 Home equity lines of credit 168 — 623 791 37,293 38,084 Consumer, indirect — — — — 111 111 Consumer, direct 34 4 — 38 1,983 2,021 Consumer 34 4 — 38 2,094 2,132 Total acquired loans $ 9,595 $ 1,115 $ 2,528 $ 13,238 $ 549,703 $ 562,941 Total loans $ 17,942 $ 6,902 $ 13,411 $ 38,255 $ 2,699,325 $ 2,737,580 Loans Past Due Current Loans Total Loans (Dollars in thousands) 30 - 59 days 60 - 89 days 90 + Days Total December 31, 2018 Originated loans: Commercial real estate, construction $ — $ — $ 710 $ 710 $ 123,303 $ 124,013 Commercial real estate, other 12 736 7,151 7,899 624,301 632,200 Commercial real estate 12 736 7,861 8,609 747,604 756,213 Commercial and industrial 1,678 3,520 1,297 6,495 523,712 530,207 Residential real estate 4,457 1,319 2,595 8,371 288,489 296,860 Home equity lines of credit 531 30 431 992 92,334 93,326 Consumer, indirect 3,266 488 165 3,919 403,248 407,167 Consumer, direct 308 50 42 400 71,274 71,674 Consumer 3,574 538 207 4,319 474,522 478,841 Deposit account overdrafts — — — — 583 583 Total originated loans $ 10,252 $ 6,143 $ 12,391 $ 28,786 $ 2,127,244 $ 2,156,030 Acquired loans: Commercial real estate, construction $ 511 $ — $ — $ 511 $ 11,893 $ 12,404 Commercial real estate, other 523 457 233 1,213 183,498 184,711 Commercial real estate 1,034 457 233 1,724 195,391 197,115 Commercial and industrial 111 13 18 142 35,395 35,537 Residential real estate 6,124 1,823 1,885 9,832 287,105 296,937 Home equity lines of credit 238 233 534 1,005 39,648 40,653 Consumer, indirect — — — — 136 136 Consumer, direct 23 6 — 29 2,341 2,370 Consumer 23 6 — 29 2,477 2,506 Total acquired loans $ 7,530 $ 2,532 $ 2,670 $ 12,732 $ 560,016 $ 572,748 Total loans $ 17,782 $ 8,675 $ 15,061 $ 41,518 $ 2,687,260 $ 2,728,778 Delinquency trends remained stable, as 98.6% of Peoples' portfolio was considered “current” at March 31, 2019 , compared to 98.5% at December 31, 2018. Credit Quality Indicators As discussed in Note 1 Summary of Significant Accounting Policies of the Notes to the Consolidated Financial Statements included in Peoples' 2018 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. 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 loan 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 “not rated.” The following table summarizes the risk category of loans within Peoples' loan portfolio based upon the most recent analysis performed: Pass Rated (Grades 1 - 4) Special Mention (Grade 5) Substandard (Grade 6) Doubtful (Grade 7) Not Rated Total Loans (Dollars in thousands) March 31, 2019 Originated loans: Commercial real estate, construction $ 114,901 $ — $ 1,454 $ — $ 637 $ 116,992 Commercial real estate, other 611,063 9,969 9,615 32 — 630,679 Commercial real estate 725,964 9,969 11,069 32 637 747,671 Commercial and industrial 526,379 19,957 11,734 — — 558,070 Residential real estate 14,002 259 11,682 171 271,553 297,667 Home equity lines of credit 17 — — — 90,814 90,831 Consumer, indirect 6 — — — 410,166 410,172 Consumer, direct 27 — — — 69,683 69,710 Consumer 33 — — — 479,849 479,882 Deposit account overdrafts — — — — 518 518 Total originated loans $ 1,266,395 $ 30,185 $ 34,485 $ 203 $ 843,371 $ 2,174,639 Acquired loans: Commercial real estate, construction $ 5,495 $ 1,665 $ 806 $ — $ — $ 7,966 Commercial real estate, other 156,487 6,625 8,583 90 — 171,785 Commercial real estate 161,982 8,290 9,389 90 — 179,751 Commercial and industrial 31,661 2,111 1,065 — — 34,837 Residential real estate 16,502 1,899 2,095 — 287,641 308,137 Home equity lines of credit 82 — — — 38,002 38,084 Consumer, indirect 2 — — — 109 111 Consumer, direct 26 — — — 1,995 2,021 Consumer 28 — — — 2,104 2,132 Total acquired loans $ 210,255 $ 12,300 $ 12,549 $ 90 $ 327,747 $ 562,941 Total loans $ 1,476,650 $ 42,485 $ 47,034 $ 293 $ 1,171,118 $ 2,737,580 Pass Rated (Grades 1 - 4) Special Mention (Grade 5) Substandard (Grade 6) Doubtful (Grade 7) Not Rated Total Loans (Dollars in thousands) December 31, 2018 Originated loans: Commercial real estate, construction $ 121,457 $ — $ 1,472 $ — $ 1,084 $ 124,013 Commercial real estate, other 612,099 10,898 9,203 — — 632,200 Commercial real estate 733,556 10,898 10,675 — 1,084 756,213 Commercial and industrial 476,290 45,990 7,692 — 235 530,207 Residential real estate 14,229 500 11,971 409 269,751 296,860 Home equity lines of credit 453 — — — 92,873 93,326 Consumer, indirect 8 — — — 407,159 407,167 Consumer, direct 30 — — — 71,644 71,674 Consumer 38 — — — 478,803 478,841 Deposit account overdrafts — — — — 583 583 Total originated loans $ 1,224,566 $ 57,388 $ 30,338 $ 409 $ 843,329 $ 2,156,030 Acquired loans: Commercial real estate, construction $ 8,976 $ 1,795 $ 1,633 $ — $ — $ 12,404 Commercial real estate, other 169,260 7,241 8,114 96 — 184,711 Commercial real estate 178,236 9,036 9,747 96 — 197,115 Commercial and industrial 32,471 2,008 1,058 — — 35,537 Residential real estate 17,370 1,938 2,033 137 275,459 296,937 Home equity lines of credit 33 — — — 40,620 40,653 Consumer, indirect 4 — — — 132 136 Consumer, direct 31 — — — 2,339 2,370 Consumer 35 — — — 2,471 2,506 Total acquired loans $ 228,145 $ 12,982 $ 12,838 $ 233 $ 318,550 $ 572,748 Total loans $ 1,452,711 $ 70,370 $ 43,176 $ 642 $ 1,161,879 $ 2,728,778 In the first three months of 2019, Peoples' classified loans, which are loans categorized as substandard or doubtful, increased compared to the balances at December 31, 2018 mostly due to downgrades during the quarter, which were partially offset by paydowns on classified loans. At March 31, 2019, criticized loans, which are those categorized as special mention, substandard or doubtful, declined compared to the balance at December 31, 2018 largely due to the upgrade of one commercial relationship during the first quarter of 2019.

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 (i) the borrower is currently in payment default on any of the borrower's debt; (ii) a payment default is probable in the foreseeable future without the modification; (iii) the borrower has declared or is in the process of declaring bankruptcy; and (iv) 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 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 debt with similar risk characteristics, the significance of the modification relative to the unpaid principal balance or collateral value of the debt, 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 (i) a reduction in the interest rate for the remaining life of the loan, (ii) an extension of the maturity date at an interest rate lower than the current market rate for new loans with similar risk, (iii) a temporary period of interest-only payments, and (iv) a reduction in the contractual payment amount for either a short period or the remaining term of the loan.

Loans modified in a TDR that were fully paid down, charged-off or foreclosed upon by period-end are not reported. Peoples did not have any originated or acquired 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 debtors whose terms have been modified in a TDR.

Decreases in expected cash flows of acquired purchased credit impaired loans are recognized as an impairment, with the amount of the expected loss included in management's evaluation of the appropriateness of the allowance for loan losses. The methods utilized to estimate the required allowance for loan losses for non-impaired acquired loans are similar to those utilized for originated loans; however, Peoples records a provision for loan losses only when the computed allowance exceeds the remaining fair value adjustment.

Long-Term Borrowings	Long-Term Borrowings The following table summarizes Peoples' long-term borrowings: March 31, 2019 December 31, 2018 (Dollars in thousands) Balance Weighted- Balance Weighted- FHLB putable, non-amortizing, fixed-rate advances $ 85,000 2.05 % $ 85,000 2.05 % FHLB amortizing, fixed-rate advances 13,670 1.73 % 17,361 2.09 % Junior subordinated debt securities 7,325 7.55 % 7,283 7.83 % Total long-term borrowings $ 105,995 2.38 % $ 109,644 2.44 % Peoples continually evaluates its overall balance sheet position given the interest rate environment. During the first three months of 2019, no additional borrowings were entered into, and one long-term FHLB non-amortizing advance in the amount of $30.0 million was reclassified to short-term borrowings as the maturity became less than one year. As of March 31, 2019 , Peoples' had one remaining FHLB putable option-based advance. The FHLB has the option, at its sole discretion, to terminate the advance after the initial fixed rate period of three months, requiring full repayment of the advance by Peoples prior to the stated maturity. If the 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. Peoples is required to make quarterly interest payments. The amortizing, fixed-rate FHLB advances have a fixed rate for the term of each advance, with maturities ranging from two to thirteen 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. Effective April 3, 2019, Peoples terminated the Credit Agreement, dated as of March 4, 2016, between Peoples, as Borrower, and Raymond James Bank, N.A., as Lender (the "RJB Credit Agreement"), with a revolving line of credit in the maximum aggregate principal amount of $15.0 million .

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 consecutive years out of the employee’s last ten years with Peoples while an eligible employee. For employees hired on or after January 1, 2003, the amount of postretirement benefit is based on 2% of the employee’s annual compensation during the years 2003 through 2009, plus accrued interest. Effective January 1, 2010, the pension plan was closed to new entrants. Effective March 1, 2011, the accrual of pension plan benefits for all participants was frozen. Peoples recognized this freeze as a curtailment as of December 31, 2010 and March 1, 2011, under the terms of the pension plan. Effective July 1, 2013, a participant in the pension plan who is employed by Peoples may elect to receive or to commence receiving such person's retirement benefits as of the later of such person's normal retirement date or the first day of the month first following the date such person makes an election to receive his or her retirement benefits. Peoples also provides post-retirement health and life insurance benefits to 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: Pension Benefits Three Months Ended March 31, (Dollars in thousands) 2019 2018 Interest cost $ 109 $ 105 Expected return on plan assets (195 ) (147 ) Amortization of net loss 19 28 Net periodic income $ (67 ) $ (14 ) Postretirement Benefits Three Months Ended March 31, (Dollars in thousands) 2019 2018 Interest cost $ 1 $ 1 Amortization of net gain (2 ) (2 ) Net periodic income $ (1 ) $ (1 ) There were no settlement charges recorded during the three months ended March 31, 2019 and March 31, 2018 under the noncontributory defined benefit pension plan.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging [Text Block]	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. Derivatives and Hedging Activities - Risk Management Objective of Using Derivatives 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 derivatives 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 derivatives 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, 2019 , Peoples had entered into twelve interest rate swap contracts with an aggregate notional value of $ 110.0 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, which will continue to be rolled through the life of the swaps. Amounts reported in accumulated other comprehensive loss ("AOCL"), related to derivatives 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, 2019 Peoples had reclassifications of gains to interest expense of $83,000 , and during the three months ended March 31, 2018 , Peoples had reclassifications of losses to interest expense of $12,000 . For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of each derivative is reported in AOCL (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 derivative hedging instrument with the changes in cash flows of the designated hedged transaction. The reset dates and the payment dates on the 90-day advances used to fund the swaps are matched to the reset dates and payment dates on the receipt of the 3-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 amount of pre-tax AOCL for Peoples' cash flow hedges was $ 745,000 at March 31, 2019 . Additionally, Peoples had $ 19,000 in reclassifications to expense in the three months ended March 31, 2019 and $ 30,000 in reclassifications to earnings in the three months ended March 31, 2018 . The following table summarizes information about the interest rate swaps designated as cash flow hedges: (Dollars in thousands) March 31, December 31, Notional amount $ 110,000 $ 110,000 Weighted average pay rates 2.37 % 2.37 % Weighted average receive rates 2.30 % 2.57 % Weighted average maturity 5.9 years 6.2 years Unrealized (losses) gains $ (589 ) $ 860 The following table presents net losses (gains) recorded in AOCL and in the Unaudited Consolidated Statements of Income related to the cash flow hedges: Three Months Ended March 31, (Dollars in thousands) 2019 2018 Amount of loss (gain) recognized in AOCL, pre-tax $ 1,833 $ (1,378 ) Amount of (loss) gain recognized in other non-interest income $ (19 ) $ 30 The following table reflects the cash flow hedges included in the Consolidated Balance Sheets: 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 $ 40,000 $ 1,333 $ 60,000 $ 2,093 Total included in other assets $ 40,000 $ 1,333 $ 60,000 $ 2,093 Included in liabilities: Interest rate swaps related to debt $ 70,000 $ 2,216 $ 50,000 $ 1,111 Total included in other liabilities $ 70,000 $ 2,216 $ 50,000 $ 1,111 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. Peoples had interest rate swaps associated with commercial loans with a gross notional value of $ 434.9 million and fair value of $ 4.2 million of equally offsetting assets and liabilities at March 31, 2019 , and a gross notional value of $ 453.4 million and fair value of $ 2.5 million of equally offsetting assets and liabilities at December 31, 2018 . 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 included in the Consolidated Balance Sheets at: 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 $ 217,428 $ 4,189 $ 226,662 $ 2,451 Total included in other assets $ 217,428 $ 4,189 $ 226,662 $ 2,451 Included in liabilities: Interest rate swaps related to commercial loans $ 217,428 $ 4,189 $ 226,662 $ 2,451 Total included in other liabilities $ 217,428 $ 4,189 $ 226,662 $ 2,451 Fair Values of Derivative Instruments on the Balance Sheet Peoples' fair value of the derivative financial instruments was $ 5.5 million in an asset position and $ 6.4 million in a liability position at March 31, 2019 , and there was $ 4.5 million in an asset position and $ 3.6 million in a liability position at December 31, 2018 . The amounts are recorded in other assets, and accrued expenses and other liabilities on the Unaudited Consolidated Balance Sheet at the date indicated. At March 31, 2019, Peoples had cash of $4.8 million pledged against the interest rate swaps. At December 31, 2018, Peoples had no cash pledged against interest rate swaps, however, the counterparties had pledged $130,000 to Peoples.

Disclosure of Compensation Related Costs, Share-based Payments [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 stock awards, stock appreciation rights ("SARs"), performance units and unrestricted common share awards to employees and non-employee directors. The total number of common shares currently 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. Prior to 2007, Peoples granted nonqualified and incentive stock options to employees and nonqualified stock options to non-employee directors under the 2006 Equity Plan and predecessor plans. 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 2018, the Board of Directors granted unrestricted common shares to non-employee directors and to all 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. Since 2018, common shares awarded to non-employee directors have vested immediately upon grant with no restrictions. Restrictions on restricted common shares awarded to employees expire after periods ranging from one to three years . In the first three months of 2019 , Peoples granted an aggregate of 117,200 restricted common shares subject to performance-based vesting to officers and key employees with restrictions that will lapse three years after the grant date provided that in order for the restricted common shares to vest in full, Peoples must have reported positive net income and maintained a well capitalized status by regulatory standards for each of the three fiscal years preceding the vesting date. During the first three months of 2019 , Peoples granted, to certain key employees, an aggregate of 1,000 restricted common shares subject to time-based vesting with restrictions that will lapse after periods ranging from immediate grant date vesting to vesting three years after the grant date. The following table summarizes the changes to Peoples’ restricted common shares for the three months ended March 31, 2019 : 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 43,679 $ 29.64 175,772 $ 31.08 Awarded 1,000 31.92 117,200 32.20 Released — — 33,400 17.86 Forfeited 250 31.10 141 35.43 Outstanding at March 31 44,429 $ 29.69 259,431 $ 33.29 For the three months ended March 31, 2019 , the total intrinsic value for restricted common shares released was $ 1.1 million compared to $2.9 million for the three months ended March 31, 2018 . 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. As of March 31, 2019, one of seven performance unit awards had been forfeited as one of the individuals granted a performance unit award left Peoples before meeting the minimum service requirement to retain the performance unit award. The performance unit awards granted cover the performance period beginning January 1, 2018 and ending on December 31, 2019, and are subject to two performance goals. Twenty-five percent of the performance units subject to each award will vest if, but only if, the related company-specific target performance goal is achieved. The remaining 75% of the performance units subject to each award will vest based on the relative performance of Peoples compared to a defined peer group (measured by percentile ranking) with respect to the related maximum performance goal. If, for the performance period, the target level of achievement for the first performance goal and/or the maximum level of achievement for the second performance goal is not reached, the dollar amount represented by the performance units associated with each performance goal will be adjusted to reflect the level of performance achieved. After the vesting date, the participant will receive that number of common shares of Peoples equal to (i) the aggregate number of the participant's performance units (and equivalent dollar value of such performance units) that vested based on the performance achieved under both performance goals (ii) divided by the fair market value of a common share of Peoples on the date the performance units are deemed to have vested (which will be the last day of the performance period) and rounded down to the nearest whole common share. 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 on the grant date, for the portion of awards that is expected to vest over the vesting period. For performance unit awards, Peoples recognizes stock-based compensation over the performance period, based on the portion of the awards that is 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 up to 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) 2019 2018 Total stock-based compensation expense $ 1,208 $ 1,086 Recognized tax benefit (254 ) (228 ) Net expense recognized $ 954 $ 858 Restricted common shares were the primary form of stock-based compensation awards granted by Peoples in the three months ended March 31, 2019 and 2018. The fair value of restricted common share awards on the grant date is the market price of Peoples' common shares. Total unrecognized stock-based compensation expense related to unvested awards was $ 4.3 million at March 31, 2019 , which will be recognized over a weighted-average period of 2.2 years . On January 31, 2018, Peoples granted, to non-employee directors, an aggregate of 3,200 unrestricted common shares, which resulted in an additional $102,000 of stock-based compensation expense being recognized. On February 14, 2018, an aggregate of 11,112 unrestricted common shares were granted as a one-time special award to all full-time and part-time employees who did not already participate in the 2006 Equity Plan, with a related stock-based compensation expense of $388,000 being recognized. For the three months ended March 31, 2019 and 2018, Peoples recorded $39,000 and $44,000 , respectively, of stock-based compensation associated with the performance unit awards. Additionally, Peoples recognized $16,000 and $14,000 of stock-based compensation associated with the employee stock purchase plan, based on purchases by employees thereunder, in the three months ended March 31, 2019 and 2018, respectively.

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 accounting pronouncements should be read in conjunction with Note 1 Summary of Significant Accounting Policies of the Notes to the Consolidated Financial Statements included in Peoples’ 2018 Form 10-K. Accounting Standards Update ("ASU") 2017-04 - Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The amendments in this ASU simplify how an entity is required to test goodwill for impairment by eliminating the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge. This accounting guidance will be effective for interim and annual reporting periods beginning after December 15, 2019 (effective January 1, 2020 for Peoples). Peoples early adopted this new accounting guidance as of January 1, 2019, and it will be incorporated in the October 1, 2019 annual goodwill and intangible assets impairment analysis, but it is not expected to have a material impact 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 current "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 will be required to present certain financial assets carried at amortized cost, such as loans held-for-investment and held-to-maturity debt 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 Subtopic 326-20, and should be accounted for according to Topic 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. This measurement will 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 required under current US GAAP, which delays recognition until it is probable a loss has been incurred. Accordingly, Peoples expects that the adoption of the CECL model will materially affect how the allowance for loan losses is determined and could require significant increases to the allowance for loan losses. Moreover, the CECL model may create more volatility in the level of Peoples' allowance for loan losses. If required to materially increase the level of allowance for loan losses for any reason, such increase could adversely affect Peoples' business, financial condition and results of operations. The new CECL standard will become effective for interim and annual reporting periods beginning after December 15, 2019 (effective January 1, 2020 for Peoples). Peoples has a committee that meets regularly to monitor progress and oversee the project. Peoples has implemented a third-party software solution, and is utilizing the tool to run test calculations throughout 2019 in anticipation of the full implementation at the beginning of 2020. Peoples will complete model validation during 2019, and is currently refining the economic forecasting process, documenting accounting policies, reviewing business processes and evaluating potential changes to the control environment. Peoples is presently evaluating the impact that the CECL model will have on Peoples' financial statements and expects to recognize a one-time cumulative-effect adjustment to the allowance for loan loss provision as of the beginning of the first reporting period in which the new standard is effective, consistent with regulatory expectations set forth in interagency guidance issued at the end of 2016. The impact of the adoption will depend on relevant data at the adoption date, including the characteristics of the loan portfolio, macroeconomic conditions and forecasts. Peoples has not yet determined the magnitude of any such one-time cumulative-effect adjustment or of the overall impact of the new standard on Peoples' financial condition or results of operations.
