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, 2016 (“ 2016 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 of the Notes to the Consolidated Financial Statements included in Peoples’ 2016 Form 10-K, as updated by the information contained in this Form 10-Q. Management has evaluated all significant events and transactions that occurred after September 30, 2017 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. All intercompany accounts and transactions have been eliminated. The Consolidated Balance Sheet at December 31, 2016 , contained herein, has been derived from the audited Consolidated Balance Sheet included in Peoples’ 2016 Form 10-K. The preparation of the consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Results of operations for interim periods are not necessarily indicative of the results to be expected for the full year, due in part to seasonal variations and unusual or infrequently occurring items. New Accounting Pronouncements: From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board ("FASB") or other standard setting bodies that are adopted by Peoples as of the required effective dates. Accounting Standards Update ("ASU") 2017-12 - Derivatives and Hedging (Topic 815): Targeted improvements to accounting for hedging activities. The amendments in this ASU better align an entity’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. To meet that objective, the amendments expand and refine hedge accounting for both non-financial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. The amendments will be effective for interim and annual reporting periods beginning after December 15, 2018 (effective January 1, 2019 for Peoples). Peoples will adopt this new accounting guidance as required, and it is not expected to have a material impact on Peoples' consolidated financial statements. ASU 2017-11 - Earnings Per Share (Topic 260); Distinguishing Liabilities from Equity (Topic 480); Derivatives and Hedging (Topic 815): (Part 1) Accounting for certain financial instruments with down round features and (Part II), Replacement of the indefinite deferral for mandatory redeemable financial instruments of certain nonpublic entities and certain mandatory redeemable non-controlling interests with a scope exception. Part I of the update addresses the complexity of accounting for certain financial instruments with down round features such as warrants or convertible instruments and will be effective for interim and annual reporting periods beginning after December 15, 2019 (effective January 1, 2020 for Peoples). Peoples will adopt this new accounting guidance as required, and it is not expected to have a material impact on Peoples' consolidated financial statements. ASU 2017-09 - Compensation - Stock Compensation (Topic 718): Scope and Modification Accounting. An entity may change the terms or conditions of a share-based payment award for many different reasons, and the nature and effect of the change can vary significantly. Modification is currently defined as "a change in any of the terms or conditions of a share-based payment award." The amendments in this ASU provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in accordance with Topic 718. The amendments will be effective for interim and annual reporting periods beginning after December 15, 2017 (effective January 1, 2018 for Peoples). Peoples will adopt this new accounting guidance as required, and it is not expected to have a material impact on Peoples' consolidated financial statements. ASU 2017-08 - Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. The amendments in this ASU shorten the amortization period for certain callable debt securities held at a premium. The amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The amendments will be effective for interim and annual reporting periods beginning after December 15, 2018 (effective January 1, 2019 for Peoples). Peoples will adopt this new accounting guidance as required, and it is not expected to have a material impact on Peoples' consolidated financial statements. ASU 2017-07 - Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The amendments in this ASU require that an employer disaggregate the service cost component from the other components of net benefit cost. The amendments will improve the consistency, transparency, and usefulness of financial information and will be effective for interim and annual reporting periods beginning after December 15, 2017 (effective January 1, 2018 for Peoples). Peoples will adopt this new accounting guidance as required, and it will have no impact on Peoples' consolidated financial statements as the accrual for pension plan benefits for all participants was frozen as of March 1, 2011. ASU 2017-04 - Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This ASU is to 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 will adopt this new accounting guidance as required, and it is not expected to have a material impact on Peoples' consolidated financial statements. ASU 2017-01 - Business Combinations (Topic 805): Clarifying the Definition of a Business. This ASU is to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting, including acquisitions, disposals, goodwill and consideration. Phase 2 of the project will not impact Peoples' consolidated financial statements. ASU 2017-01 will become effective for interim and annual reporting periods beginning after December 15, 2017 (effective January 1, 2018 for Peoples). Peoples will adopt Phase 1 of this new accounting guidance as required and management will apply this guidance to future transactions upon adoption. Phase 2, which was released as ASU 2017-05 will not impact Peoples' consolidated financial statements. ASU 2014-09 - Revenue from Contracts with Customers (Topic 606). There are many aspects of this new accounting guidance that are still being interpreted and the FASB has issued updates to certain aspects of the guidance to address implementation issues. The FASB issued updates in March, April, May and December of 2016, and September of 2017, clarifying several areas of the guidance. These clarifications included: • Principal versus agent considerations, • Collectibility, sales tax and non-cash consideration, practical expedients for contract modifications and completed contracts, • Identification of performance obligations • Licensing implementation guidance, and • Transition provisions for public business entities that otherwise would not meet the definition of a public business entity except for a requirement to include, or the inclusion of, its financial statements or financial information in another public business entity's filing. This accounting guidance can be implemented using either a full retrospective method or a modified retrospective approach. This accounting guidance will be effective for interim and annual reporting periods beginning after December 15, 2017 (effective January 1, 2018 for Peoples). Early adoption is permitted but only for interim and annual reporting periods beginning after December 15, 2016. Peoples will adopt this new accounting guidance in 2018, as required, and expects to adopt the new guidance using the modified retrospective approach. The modified retrospective approach uses a cumulative-effect adjustment to retained earnings to reflect uncompleted contracts in the initial application of the guidance. Peoples' preliminary analysis indicates that certain non-interest income financial statement line items contain revenue streams that are in the scope of this update, the most substantial of which is insurance income. Based on Peoples’ evaluation to date, Peoples does not expect the adoption of this accounting guidance to have a significant impact on Peoples’ financial condition or results of operations; however, the review is ongoing. Peoples will continue to evaluate the impact of this accounting guidance, including any additional guidance issued, during the completion of this internal assessment. 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. 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 is currently 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. Peoples has not yet determined the magnitude of any such one-time cumulative adjustment or of the overall impact of the new standard on Peoples' financial condition or results of operations. ASU 2016-09 - Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The amendments in this ASU require all excess income tax benefits or tax deficiencies of stock awards to be recognized in the income statement when the awards vest or are settled. The amendments also allow an employer to repurchase more of an employee’s shares than it could under previous guidance for tax withholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. Peoples adopted this pronouncement as of January 1, 2017, and will continue using an estimated forfeiture rate. In the first nine months of 2017, Peoples recorded a tax benefit of $123,000 associated with the adoption of this ASU for the tax benefit of awards that settled or vested during the year, with the majority recorded in the first quarter of 2017. ASU 2016-02 - Leases (Topic 842): This ASU was issued to improve the financial reporting of leasing activities and provide a faithful representation of leasing transactions and improve understanding and comparability of a lessee's financial statements. Under the new accounting guidance, a lessee will be required to recognize assets and liabilities for leases with lease terms of more than 12 months. This ASU will require both finance and operating leases to be recognized on the balance sheet. This ASU will affect all companies and organizations that lease real estate. This ASU will become effective for interim and annual reporting periods beginning after December 15, 2018 (effective January 1, 2019 for Peoples). Peoples will adopt this new accounting guidance as required, and it is not expected to have a material impact on Peoples' consolidated financial statements. ASU 2016-01 - Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in this ASU are intended to enhance the reporting model for financial instruments to provide users of financial statements with more useful information. The amendments require equity investments to be measured at fair value with changes in fair value recognized in net income. However, a reporting organization may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment (if any,) from observable price changes in orderly transactions for similar investments of the same issuer. This ASU will be effective for fiscal years beginning after December 15, 2017 (effective January 1, 2018 for Peoples). Peoples is currently evaluating the impact of adopting the new accounting guidance on Peoples' consolidated financial statements which may result in an impact to the income statement on a quarterly and annual basis, as market values fluctuate. Peoples will adopt this accounting guidance as of the required effective date. As of September 30, 2017, Peoples had net unrealized gains on equity securities of $6.5 million .

Fair Value of Financial Instruments	Fair Value of Financial Instruments Available-for-sale securities measured at fair value on a recurring basis were comprised of the following: Fair Value Measurements at Reporting Date Using (Dollars in thousands) Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Fair Value September 30, 2017 Obligations of: States and political subdivisions $ 104,560 $ — $ 104,560 $ — Residential mortgage-backed securities 672,106 — 672,106 — Commercial mortgage-backed securities 7,128 — 7,128 — Bank-issued trust preferred securities 5,154 — 5,154 — Equity securities 8,073 7,914 159 — Total available-for-sale securities $ 797,021 $ 7,914 $ 789,107 $ — December 31, 2016 Obligations of: U.S. government sponsored agencies $ 1,000 $ — $ 1,000 $ — States and political subdivisions 117,230 — 117,230 — Residential mortgage-backed securities 626,567 — 626,567 — Commercial mortgage-backed securities 19,291 — 19,291 — Bank-issued trust preferred securities 4,899 — 4,899 — Equity securities 8,953 8,734 219 — Total available-for-sale securities $ 777,940 $ 8,734 $ 769,206 $ — Held-to-maturity securities reported at fair value were comprised of the following: Fair Value at Reporting Date Using (Dollars in thousands) Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Fair Value (Level 1) (Level 2) (Level 3) September 30, 2017 Obligations of: States and political subdivisions $ 4,463 $ — $ 4,463 $ — Residential mortgage-backed securities 33,690 — 33,690 — Commercial mortgage-backed securities 4,655 — 4,655 — Total held-to-maturity securities $ 42,808 $ — $ 42,808 $ — December 31, 2016 Obligations of: States and political subdivisions $ 4,041 $ — $ 4,041 $ — Residential mortgage-backed securities 33,762 — 33,762 — Commercial mortgage-backed securities 5,424 — 5,424 — Total held-to-maturity securities $ 43,227 $ — $ 43,227 $ — 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 inputs) 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. Certain financial assets and financial liabilities are measured at fair value on a non-recurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). Financial assets measured at fair value on a non-recurring basis included the following: 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 market value provided by independent, licensed or certified appraisers (Level 2 inputs). At September 30, 2017 , impaired loans with an aggregate outstanding principal balance of $33.0 million were measured and reported at a fair value of $27.0 million . For the three and nine months ended September 30, 2017 , Peoples recognized $83,000 and $ 408,000 of recoveries on impaired loans, respectively, through the allowance for loan losses. The following table presents the fair values of financial assets and liabilities carried on Peoples’ Unaudited Consolidated Balance Sheets, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis or non-recurring basis: September 30, 2017 December 31, 2016 (Dollars in thousands) Carrying Amount Fair Value Carrying Amount Fair Value Financial assets: Cash and cash equivalents $ 70,043 $ 70,043 $ 66,146 $ 66,146 Investment securities 877,555 878,200 859,455 859,538 Loans (1) 2,311,696 2,252,054 2,210,529 2,152,544 Bank premises and equipment, net 51,777 51,777 53,616 53,616 Bank owned life insurance 61,696 61,696 60,225 60,225 Financial liabilities: Deposits $ 2,664,682 $ 2,664,513 $ 2,509,722 $ 2,512,647 Short-term borrowings 193,717 193,717 305,607 305,607 Long-term borrowings 195,890 195,857 145,155 145,106 Cash flow hedges (2) 916 916 1,779 1,779 (1) Includes loans held for sale. (2) For additional information, see Note 9 of the Notes to the Unaudited Consolidated Financial Statements. The methodologies for estimating the fair value of financial assets and liabilities that are measured at fair value on a recurring or non-recurring basis are discussed above. 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: 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 inputs). In the current whole loan market, financial investors are generally requiring a higher rate of return than the return inherent in loans if held to maturity given the lack of market liquidity. This divergence accounts for the majority of the difference in carrying amount over fair value. Deposits: The fair value of fixed maturity certificates of deposit is estimated using a discounted cash flow calculation based on current rates offered for deposits of similar remaining maturities (Level 2 inputs). 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 inputs). Cash flow hedges: Cash flow hedges are recognized in the Unaudited Consolidated Balance Sheets at their fair value within other assets. 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 inputs). Customer relationships, deposit base, banking center networks, and other information required to compute Peoples’ aggregate fair value are not included in the above information. Accordingly, the above fair values are not intended to represent the aggregate fair value of Peoples.

At September 30, 2017 , there were no securities of a single issuer that exceeded 10% of stockholders' equity. The gross gains and gross losses realized by Peoples from sales of available-for-sale securities for the periods ended September 30 were as follows: Three Months Ended Nine Months Ended September 30, September 30, (Dollars in thousands) 2017 2016 2017 2016 Gross gains realized $ 1,877 $ — $ 2,235 $ 863 Gross losses realized 16 1 16 1 Net gain (loss) realized $ 1,861 $ (1 ) $ 2,219 $ 862 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. The following table presents a summary of available-for-sale investment securities that had an unrealized loss: Less than 12 Months 12 Months or More Total (Dollars in thousands) Fair Value Unrealized Loss No. of Securities Fair Value Unrealized Loss No. of Securities Fair Value Unrealized Loss September 30, 2017 Obligations of: States and political subdivisions $ 7,622 $ 62 6 $ 3,957 $ 136 1 $ 11,579 $ 198 Residential mortgage-backed securities 300,639 3,348 77 163,685 5,087 51 464,324 8,435 Commercial mortgage-backed securities 3,875 17 2 — — — 3,875 17 Bank-issued trust preferred securities — — — 2,818 181 3 2,818 181 Equity securities — — — 112 64 1 112 64 Total $ 312,136 $ 3,427 85 $ 170,572 $ 5,468 56 $ 482,708 $ 8,895 December 31, 2016 Obligations of: States and political subdivisions $ 23,501 $ 263 28 $ — $ — — $ 23,501 $ 263 Residential mortgage-backed securities 427,088 8,495 108 46,631 2,498 22 473,719 10,993 Commercial mortgage-backed securities 7,770 87 4 — — — 7,770 87 Bank-issued trust preferred securities — — — 2,637 361 3 2,637 361 Equity securities 263 3 1 110 65 1 373 68 Total $ 458,622 $ 8,848 141 $ 49,378 $ 2,924 26 $ 508,000 $ 11,772 Management systematically evaluates available-for-sale investment securities for other-than-temporary declines in fair value on a quarterly basis. At September 30, 2017 , 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 September 30, 2017 and December 31, 2016 were largely attributable to changes in market interest rates and spreads since the securities were purchased. At September 30, 2017 , 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 four positions, consisted of privately issued mortgage-backed securities with all of the underlying mortgages originated prior to 2004. Two of the four positions had a fair value of less than 90% of their book value, with an aggregate book and fair value of $0.7 million and $0.4 million , 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. Furthermore, the unrealized losses with respect to the three bank-issued trust preferred securities that had been in an unrealized loss position for twelve months or more at September 30, 2017 were primarily attributable to the floating-rate nature of those investments, the current interest rate environment and spreads within that sector. The table below presents the amortized cost, fair value and total weighted-average yield of available-for-sale securities by contractual maturity at September 30, 2017 . 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. Rates are calculated on a fully tax-equivalent basis using a 35% federal income tax rate.

Pledged Securities Peoples had pledged available-for-sale investment securities with carrying values of $543.1 million and $517.9 million at September 30, 2017 and December 31, 2016 , respectively, and held-to-maturity investment securities with carrying values of $19.0 million and $20.0 million at September 30, 2017 and December 31, 2016 , 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 $7.9 million and $9.2 million at September 30, 2017 and December 31, 2016 , respectively, and held-to-maturity securities with carrying values of $20.9 million and $22.2 million at September 30, 2017 and December 31, 2016 , 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 northeastern Kentucky. Acquired loans consist of loans purchased in 2012 or thereafter in a business combination. Loans that were acquired and subsequently re-underwritten, are reported as originated upon execution of such credit actions (for example, renewals and increases in lines of credit). The major classifications of loan balances (in each case, net of deferred fees and costs) excluding loans held for sale, were as follows: (Dollars in thousands) September 30, December 31, 2016 Originated loans: Commercial real estate, construction $ 111,187 $ 84,626 Commercial real estate, other 573,256 531,557 Commercial real estate 684,443 616,183 Commercial and industrial 407,468 378,131 Residential real estate 304,094 307,490 Home equity lines of credit 88,421 85,617 Consumer, indirect 335,436 252,024 Consumer, other 68,286 67,579 Consumer 403,722 319,603 Deposit account overdrafts 507 1,080 Total originated loans $ 1,888,655 $ 1,708,104 Acquired loans: Commercial real estate, construction $ 8,565 $ 10,100 Commercial real estate, other 174,157 204,466 Commercial real estate 182,722 214,566 Commercial and industrial 36,462 44,208 Residential real estate 194,950 228,435 Home equity lines of credit 22,366 25,875 Consumer, indirect 408 808 Consumer, other 1,472 2,940 Consumer 1,880 3,748 Total acquired loans $ 438,380 $ 516,832 Loans, net of deferred fees and costs $ 2,327,035 $ 2,224,936 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) September 30, December 31, Commercial real estate, other $ 8,235 $ 11,476 Commercial and industrial 818 1,573 Residential real estate 20,497 23,306 Consumer 41 76 Total outstanding balance $ 29,591 $ 36,431 Net carrying amount $ 20,581 $ 26,524 Changes in the accretable yield for purchased credit impaired loans for the nine months ended September 30, 2017 were as follows: (Dollars in thousands) Accretable Yield Balance, December 31, 2016 $ 7,132 Reclassification from nonaccretable to accretable 1,285 Accretion (1,279 ) Balance, September 30, 2017 $ 7,138 Peoples completes annual re-estimations of cash flows on acquired purchased credit impaired loans in August of each year. The above reclassification from nonaccretable to accretable related to the re-estimation of cash flows on the purchased credit impaired loan portfolio, coupled with the loans performing better than expected. The majority of the reclassification related to prepayment speeds decreasing in the residential portfolio, resulting in higher total expected cash flows. 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. Peoples pledges certain loans secured by 1-4 family and multifamily residential mortgages under a blanket collateral agreement to secure borrowings from the FHLB. The amount of such pledged loans totaled $490.1 million and $542.5 million at September 30, 2017 and December 31, 2016 , respectively. Peoples also pledges commercial loans to secure borrowings with the FRB. The outstanding balances of these loans totaled $84.0 million and $152.0 million at September 30, 2017 and December 31, 2016 , 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.

Credit Quality Indicators As discussed in Note 1 of the Notes to the Consolidated Financial Statements included in Peoples' 2016 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 in 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) September 30, 2017 Originated loans: Commercial real estate, construction $ 104,446 $ 5,510 $ 776 $ — $ 455 $ 111,187 Commercial real estate, other 541,073 21,062 11,121 — — 573,256 Commercial real estate 645,519 26,572 11,897 — 455 684,443 Commercial and industrial 382,332 18,943 6,157 — 36 407,468 Residential real estate 18,717 1,033 11,499 182 272,663 304,094 Home equity lines of credit 596 — — — 87,825 88,421 Consumer, indirect 59 9 — — 335,368 335,436 Consumer, other 38 — — — 68,248 68,286 Consumer 97 9 — — 403,616 403,722 Deposit account overdrafts — — — — 507 507 Total originated loans $ 1,047,261 $ 46,557 $ 29,553 $ 182 $ 765,102 $ 1,888,655 Acquired loans: Commercial real estate, construction $ 8,513 $ — $ 52 $ — $ — $ 8,565 Commercial real estate, other 157,610 8,057 8,490 — — 174,157 Commercial real estate 166,123 8,057 8,542 — — 182,722 Commercial and industrial 34,651 220 1,591 — — 36,462 Residential real estate 13,082 604 1,365 — 179,899 194,950 Home equity lines of credit 143 — — — 22,223 22,366 Consumer, indirect 19 — — — 389 408 Consumer, other 42 — — — 1,430 1,472 Consumer 61 — — — 1,819 1,880 Total acquired loans $ 214,060 $ 8,881 $ 11,498 $ — $ 203,941 $ 438,380 Total loans $ 1,261,321 $ 55,438 $ 41,051 $ 182 $ 969,043 $ 2,327,035 Pass Rated (Grades 1 - 4) Special Mention (Grade 5) Substandard (Grade 6) Doubtful (Grade 7) Not Rated Total Loans (Dollars in thousands) December 31, 2016 Originated loans: Commercial real estate, construction $ 73,423 $ — $ 826 $ — $ 10,377 $ 84,626 Commercial real estate, other 505,029 11,855 14,673 — — 531,557 Commercial real estate 578,452 11,855 15,499 — 10,377 616,183 Commercial and industrial 346,791 15,210 16,130 — — 378,131 Residential real estate 47,336 957 12,828 304 246,065 307,490 Home equity lines of credit 465 — 135 — 85,017 85,617 Consumer, indirect 15 13 — — 251,996 252,024 Consumer, other 50 — — — 67,529 67,579 Consumer 65 13 — — 319,525 319,603 Deposit account overdrafts — — — — 1,080 1,080 Total originated loans $ 973,109 $ 28,035 $ 44,592 $ 304 $ 662,064 $ 1,708,104 Acquired loans: Commercial real estate, construction $ 10,046 $ — $ 54 $ — $ — $ 10,100 Commercial real estate, other 181,781 12,475 10,210 — — 204,466 Commercial real estate 191,827 12,475 10,264 — — 214,566 Commercial and industrial 42,809 227 978 194 — 44,208 Residential real estate 17,170 709 1,404 — 209,152 228,435 Home equity lines of credit 202 — — — 25,673 25,875 Consumer, indirect 51 — — — 757 808 Consumer, other 53 — — — 2,887 2,940 Consumer 104 — — — 3,644 3,748 Total acquired loans $ 252,112 $ 13,411 $ 12,646 $ 194 $ 238,469 $ 516,832 Total loans $ 1,225,221 $ 41,446 $ 57,238 $ 498 $ 900,533 $ 2,224,936 In the first nine months of 2017, Peoples' classified loans, which are loans categorized as substandard or doubtful, declined compared to the balances at December 31, 2016 mostly due to loan payoffs.

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 or not a concession has been granted to the borrower. Key factors considered by Peoples include the borrower's ability to access funds at a market rate for 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.

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 nonimpaired 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. During the third quarter of 2017, Peoples completed its reforecast of the estimated cash flows expected to be collected on purchased credit impaired loans. As a result, Peoples recorded an additional provision for loan losses for acquired loans during the third quarter of 2017. During the first nine months of 2017, Peoples also recognized a recovery of loan losses that was related to an acquired purchased credit impaired loan that was paid off. The following table presents activity in the allowance for loan losses for acquired loans for the three and nine months ended September 30 : Three Months Ended Nine Months Ended (Dollars in thousands) September 30, 2017 September 30, 2016 September 30, 2017 September 30, 2016 Purchased credit impaired loans: Balance, beginning of period $ 90 $ 197 $ 233 $ 240 Charge-offs — (16 ) — (67 ) Recoveries — — — — Net charge-offs — (16 ) — (67 ) Provision for (recovery of) loan losses 25 77 (118 ) 85 Balance, September 30 $ 115 $ 258 $ 115 $ 258

During the first nine months of 2017, Peoples borrowed an additional $75.0 million of long-term FHLB non-amortizing advances, which have interest rates ranging from 1.20% to 2.03% and mature between 2018 and 2022. As of September 30, 2017 , Peoples' FHLB putable and callable national market repurchase agreements had no remaining putable or callable options. 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 ten to twenty 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. Peoples has entered into interest rate swaps as part of its interest rate risk management strategy. These interest rate swaps are designated as cash flow hedges and involve the receipt of variable rate amounts from a counterparty in exchange for Peoples making fixed payments. As of September 30, 2017, Peoples had seven interest rate swaps with a notional value of $ 60.0 million associated with Peoples' cash outflows for various FHLB advances. The swaps become effective in 2018, roughly to coincide with the maturity of existing FHLB advances. Additional information regarding Peoples' interest rate swaps can be found in Note 9 of the Notes to the Unaudited Consolidated Financial Statements. Peoples maintains a multi-year unsecured $15.0 million revolving credit facility (the “Credit Facility”) with Raymond James Bank, N.A. that matures on March 4, 2019. Borrowings under the Credit Facility may be used: (i) to make acquisitions; (ii) to make stock repurchases; (iii) for working capital needs; and (iv) for other general corporate purposes. Each loan under the Credit Facility will bear interest per annum at a rate equal to 3.00% plus the one-month LIBOR rate, which rate will reset monthly. As of September 30, 2017, there were no borrowings outstanding under the Credit Facility. Additional information regarding the Credit Facility can be found in Note 9 of the Notes to the Consolidated Financial Statements included in Peoples' 2016 Form 10-K.

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 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. 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 Peoples 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’ policy is to fund the cost of the health benefits as they arise. The following tables detail the components of the net periodic cost for the plans: Pension Benefits Three Months Ended Nine Months Ended September 30, September 30, (Dollars in thousands) 2017 2016 2017 2016 Interest cost $ 112 $ 110 $ 338 $ 329 Expected return on plan assets (138 ) (123 ) (415 ) (369 ) Amortization of net loss 26 23 77 71 Net periodic cost $ — $ 10 $ — $ 31 Postretirement Benefits Three Months Ended Nine Months Ended September 30, September 30, (Dollars in thousands) 2017 2016 2017 2016 Interest cost $ 1 $ 1 $ 3 $ 3 Amortization of net loss (1 ) (2 ) (5 ) (5 ) Net periodic cost $ — $ (1 ) $ (2 ) $ (2 ) There were no settlement charges recorded in the three or nine months ended September 30, 2017 or September 30, 2016 under the noncontributory defined benefit pension plan.

Financial Instruments with Off-Balance Sheet Risk [Abstract]
Financial Instruments Disclosure [Text Block]	Financial Instruments with Off-Balance Sheet Risk 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 value 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. Fair Values of Derivative Instruments on the Balance Sheet Peoples' fair value of the derivative financial instruments was $ 4.8 million in an asset position and $ 3.9 million in a liability position at September 30, 2017 , and there was $ 5.0 million in an asset position and $ 3.2 million in a liability position at December 31, 2016 . The amounts are recorded in other assets, and accrued expenses and other liabilities on the consolidated balance sheet at the periods indicated. 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 September 30, 2017 , Peoples had seven interest rate swaps with a notional value of $ 60.0 million associated with Peoples' cash outflows for various FHLB advances. For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of each derivative is initially reported in accumulated other comprehensive income ("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 derivative hedging instrument with the changes in cash flows of the designated hedged transaction. Peoples hedged its exposure to the variability in future cash flows for forecasted transactions over a maximum period of 13 months (excluding forecasted transactions related to the payment of variable interest on existing financial instruments). Peoples entered into the seven interest rate swap contracts, described above, whereby 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 received floating rate component is intended to offset the rate on the rolling three-month FHLB advances. Amounts reported in AOCI 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 and nine months ended September 30, 2017 , and September 30, 2016 , Peoples had no reclassifications to interest expense. Peoples estimates that no interest expense amount will be reclassified in the fourth quarter of 2017 prior to adoption of the new accounting standards. The amount of accumulated other comprehensive pre-tax income for Peoples' cash flow hedges was $ 1.0 million at September 30, 2017 . There were no pre-tax net losses recorded for the nine months ended September 30, 2017 . Additionally, Peoples had no reclassifications to earnings in the three months or nine months ended September 30, 2017 or September 30, 2016 . Non-Designated Hedges Peoples maintains an interest rate protection program for commercial loan customers, which was established in 2010. Under this program, Peoples provides its customer with a fixed-rate loan while creating a variable-rate asset for Peoples by the customer entering into an interest rate swap with Peoples on terms that match the loan. Peoples offsets its risk exposure 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 notional value of $ 334.2 million and fair value of $ 3.5 million of equally offsetting assets and liabilities at September 30, 2017 , and a notional value of $ 247.3 million and fair value of $ 3.2 million of equally offsetting assets and liabilities at December 31, 2016 . These interest rate swaps did not have a material impact on Peoples' results of operation or financial condition.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-Based Compensation Under the Peoples Bancorp Inc. Second Amended and Restated 2006 Equity Plan (the "2006 Equity Plan"), Peoples may grant, among other awards, nonqualified stock options, incentive stock options, restricted stock awards, stock appreciation rights ("SARs") and unrestricted share awards to employees and non-employee directors. The total number of common shares available under the 2006 Equity Plan is 1,081,260 . The maximum number of common shares that can be issued for incentive stock options is 800,000 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 2009, Peoples has granted restricted common shares to employees and restricted common shares to non-employee directors subject to the terms and conditions prescribed by 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. Stock Appreciation Rights SARs granted to employees have an exercise price equal to the fair market value of Peoples’ common shares on the date of grant and will be settled using common shares of Peoples. Additionally, the SARs granted to employees vested three years after the respective grant dates and are to expire ten years from the respective date of grant. The most recent grant of SARs occurred in 2008. The following table summarizes the changes to Peoples' SARs for the nine months ended September 30, 2017 : Number of Common Shares Subject to SARs Weighted- Average Exercise Price Weighted-Average Remaining Contractual Life Aggregate Intrinsic Value Outstanding at January 1 2,338 $ 27.37 Exercised 2,024 27.93 Outstanding at September 30 314 $ 23.77 0.4 years $ 3,083 Exercisable at September 30 314 $ 23.77 0.4 years $ 3,083 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 restricted common shares awarded to non-employee directors expire after six months , while the restrictions on restricted common shares awarded to employees expire after periods ranging from one to three years . In the first nine months of 2017, Peoples granted an aggregate of 61,547 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 nine months of 2017, Peoples granted, to certain key employees, an aggregate of 4,250 restricted common shares subject to time-based vesting with restrictions that will lapse three years after the grant date. Peoples also granted, to non-employee directors, an aggregate of 3,300 restricted common shares subject to time-based vesting with restrictions that will lapse six months after the grant date. The following table summarizes the changes to Peoples’ restricted common shares for the nine months ended September 30, 2017 : 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 40,316 $ 21.85 142,415 $ 21.95 Awarded 7,550 31.36 61,457 32.42 Released 7,150 26.96 21,050 21.74 Forfeited 2,300 24.69 5,854 24.89 Outstanding at September 30 38,416 $ 22.59 176,968 $ 25.51 For the nine months ended September 30, 2017 , the total intrinsic value for restricted common shares released was $ 0.9 million compared to $0.7 million for the nine months ended September 30, 2016 . Stock-Based Compensation Peoples recognizes stock-based compensation expense, which is included as a component of Peoples' salaries and employee benefit costs, based on the estimated fair value of the awards on the grant date. The following table summarizes the amount of stock-based compensation expense and related tax benefit recognized for each period: Three Months Ended Nine Months Ended September 30, September 30, (Dollars in thousands) 2017 2016 2017 2016 Total stock-based compensation expense $ 351 $ 346 $ 1,362 $ 1,009 Recognized tax benefit (123 ) (121 ) (477 ) (353 ) Net expense recognized $ 228 $ 225 $ 885 $ 656 Total unrecognized stock-based compensation expense related to unvested awards was $ 1.8 million at September 30, 2017 , which will be recognized over a weighted-average period of 1.9 years . Performance Unit Award Agreement Under the 2006 Equity Plan, Peoples may award 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 officers with a maximum aggregate dollar amount of $1.3 million represented by the performance units subject to such awards, with each performance unit representing $1.00. The performance unit awards granted are for the performance period beginning January 1, 2018 and ending on December 31, 2019, and will be subject to two performance goals. Twenty-five percent of the performance units subject to each award will vest if, but only if, the related target performance goal is achieved. The remaining 75% of the performance units subject to each award will vest based on the relative performance (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 participant's performance units (and 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 on the date of such vesting and rounded down to the nearest whole common share.

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. Accounting Standards Update ("ASU") 2017-12 - Derivatives and Hedging (Topic 815): Targeted improvements to accounting for hedging activities. The amendments in this ASU better align an entity’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. To meet that objective, the amendments expand and refine hedge accounting for both non-financial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. The amendments will be effective for interim and annual reporting periods beginning after December 15, 2018 (effective January 1, 2019 for Peoples). Peoples will adopt this new accounting guidance as required, and it is not expected to have a material impact on Peoples' consolidated financial statements. ASU 2017-11 - Earnings Per Share (Topic 260); Distinguishing Liabilities from Equity (Topic 480); Derivatives and Hedging (Topic 815): (Part 1) Accounting for certain financial instruments with down round features and (Part II), Replacement of the indefinite deferral for mandatory redeemable financial instruments of certain nonpublic entities and certain mandatory redeemable non-controlling interests with a scope exception. Part I of the update addresses the complexity of accounting for certain financial instruments with down round features such as warrants or convertible instruments and will be effective for interim and annual reporting periods beginning after December 15, 2019 (effective January 1, 2020 for Peoples). Peoples will adopt this new accounting guidance as required, and it is not expected to have a material impact on Peoples' consolidated financial statements. ASU 2017-09 - Compensation - Stock Compensation (Topic 718): Scope and Modification Accounting. An entity may change the terms or conditions of a share-based payment award for many different reasons, and the nature and effect of the change can vary significantly. Modification is currently defined as "a change in any of the terms or conditions of a share-based payment award." The amendments in this ASU provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in accordance with Topic 718. The amendments will be effective for interim and annual reporting periods beginning after December 15, 2017 (effective January 1, 2018 for Peoples). Peoples will adopt this new accounting guidance as required, and it is not expected to have a material impact on Peoples' consolidated financial statements. ASU 2017-08 - Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. The amendments in this ASU shorten the amortization period for certain callable debt securities held at a premium. The amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The amendments will be effective for interim and annual reporting periods beginning after December 15, 2018 (effective January 1, 2019 for Peoples). Peoples will adopt this new accounting guidance as required, and it is not expected to have a material impact on Peoples' consolidated financial statements. ASU 2017-07 - Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The amendments in this ASU require that an employer disaggregate the service cost component from the other components of net benefit cost. The amendments will improve the consistency, transparency, and usefulness of financial information and will be effective for interim and annual reporting periods beginning after December 15, 2017 (effective January 1, 2018 for Peoples). Peoples will adopt this new accounting guidance as required, and it will have no impact on Peoples' consolidated financial statements as the accrual for pension plan benefits for all participants was frozen as of March 1, 2011. ASU 2017-04 - Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This ASU is to 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 will adopt this new accounting guidance as required, and it is not expected to have a material impact on Peoples' consolidated financial statements. ASU 2017-01 - Business Combinations (Topic 805): Clarifying the Definition of a Business. This ASU is to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting, including acquisitions, disposals, goodwill and consideration. Phase 2 of the project will not impact Peoples' consolidated financial statements. ASU 2017-01 will become effective for interim and annual reporting periods beginning after December 15, 2017 (effective January 1, 2018 for Peoples). Peoples will adopt Phase 1 of this new accounting guidance as required and management will apply this guidance to future transactions upon adoption. Phase 2, which was released as ASU 2017-05 will not impact Peoples' consolidated financial statements. ASU 2014-09 - Revenue from Contracts with Customers (Topic 606). There are many aspects of this new accounting guidance that are still being interpreted and the FASB has issued updates to certain aspects of the guidance to address implementation issues. The FASB issued updates in March, April, May and December of 2016, and September of 2017, clarifying several areas of the guidance. These clarifications included: • Principal versus agent considerations, • Collectibility, sales tax and non-cash consideration, practical expedients for contract modifications and completed contracts, • Identification of performance obligations • Licensing implementation guidance, and • Transition provisions for public business entities that otherwise would not meet the definition of a public business entity except for a requirement to include, or the inclusion of, its financial statements or financial information in another public business entity's filing. This accounting guidance can be implemented using either a full retrospective method or a modified retrospective approach. This accounting guidance will be effective for interim and annual reporting periods beginning after December 15, 2017 (effective January 1, 2018 for Peoples). Early adoption is permitted but only for interim and annual reporting periods beginning after December 15, 2016. Peoples will adopt this new accounting guidance in 2018, as required, and expects to adopt the new guidance using the modified retrospective approach. The modified retrospective approach uses a cumulative-effect adjustment to retained earnings to reflect uncompleted contracts in the initial application of the guidance. Peoples' preliminary analysis indicates that certain non-interest income financial statement line items contain revenue streams that are in the scope of this update, the most substantial of which is insurance income. Based on Peoples’ evaluation to date, Peoples does not expect the adoption of this accounting guidance to have a significant impact on Peoples’ financial condition or results of operations; however, the review is ongoing. Peoples will continue to evaluate the impact of this accounting guidance, including any additional guidance issued, during the completion of this internal assessment. 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. 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 is currently 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. Peoples has not yet determined the magnitude of any such one-time cumulative adjustment or of the overall impact of the new standard on Peoples' financial condition or results of operations. ASU 2016-09 - Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The amendments in this ASU require all excess income tax benefits or tax deficiencies of stock awards to be recognized in the income statement when the awards vest or are settled. The amendments also allow an employer to repurchase more of an employee’s shares than it could under previous guidance for tax withholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. Peoples adopted this pronouncement as of January 1, 2017, and will continue using an estimated forfeiture rate. In the first nine months of 2017, Peoples recorded a tax benefit of $123,000 associated with the adoption of this ASU for the tax benefit of awards that settled or vested during the year, with the majority recorded in the first quarter of 2017. ASU 2016-02 - Leases (Topic 842): This ASU was issued to improve the financial reporting of leasing activities and provide a faithful representation of leasing transactions and improve understanding and comparability of a lessee's financial statements. Under the new accounting guidance, a lessee will be required to recognize assets and liabilities for leases with lease terms of more than 12 months. This ASU will require both finance and operating leases to be recognized on the balance sheet. This ASU will affect all companies and organizations that lease real estate. This ASU will become effective for interim and annual reporting periods beginning after December 15, 2018 (effective January 1, 2019 for Peoples). Peoples will adopt this new accounting guidance as required, and it is not expected to have a material impact on Peoples' consolidated financial statements. ASU 2016-01 - Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in this ASU are intended to enhance the reporting model for financial instruments to provide users of financial statements with more useful information. The amendments require equity investments to be measured at fair value with changes in fair value recognized in net income. However, a reporting organization may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment (if any,) from observable price changes in orderly transactions for similar investments of the same issuer. This ASU will be effective for fiscal years beginning after December 15, 2017 (effective January 1, 2018 for Peoples). Peoples is currently evaluating the impact of adopting the new accounting guidance on Peoples' consolidated financial statements which may result in an impact to the income statement on a quarterly and annual basis, as market values fluctuate. Peoples will adopt this accounting guidance as of the required effective date. As of September 30, 2017, Peoples had net unrealized gains on equity securities of $6.5 million .

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 northeastern Kentucky. Acquired loans consist of loans purchased in 2012 or thereafter in a business combination. Loans that were acquired and subsequently re-underwritten, are reported as originated upon execution of such credit actions (for example, renewals and increases in lines of credit). The major classifications of loan balances (in each case, net of deferred fees and costs) excluding loans held for sale, were as follows: (Dollars in thousands) September 30, December 31, 2016 Originated loans: Commercial real estate, construction $ 111,187 $ 84,626 Commercial real estate, other 573,256 531,557 Commercial real estate 684,443 616,183 Commercial and industrial 407,468 378,131 Residential real estate 304,094 307,490 Home equity lines of credit 88,421 85,617 Consumer, indirect 335,436 252,024 Consumer, other 68,286 67,579 Consumer 403,722 319,603 Deposit account overdrafts 507 1,080 Total originated loans $ 1,888,655 $ 1,708,104 Acquired loans: Commercial real estate, construction $ 8,565 $ 10,100 Commercial real estate, other 174,157 204,466 Commercial real estate 182,722 214,566 Commercial and industrial 36,462 44,208 Residential real estate 194,950 228,435 Home equity lines of credit 22,366 25,875 Consumer, indirect 408 808 Consumer, other 1,472 2,940 Consumer 1,880 3,748 Total acquired loans $ 438,380 $ 516,832 Loans, net of deferred fees and costs $ 2,327,035 $ 2,224,936 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) September 30, December 31, Commercial real estate, other $ 8,235 $ 11,476 Commercial and industrial 818 1,573 Residential real estate 20,497 23,306 Consumer 41 76 Total outstanding balance $ 29,591 $ 36,431 Net carrying amount $ 20,581 $ 26,524 Changes in the accretable yield for purchased credit impaired loans for the nine months ended September 30, 2017 were as follows: (Dollars in thousands) Accretable Yield Balance, December 31, 2016 $ 7,132 Reclassification from nonaccretable to accretable 1,285 Accretion (1,279 ) Balance, September 30, 2017 $ 7,138 Peoples completes annual re-estimations of cash flows on acquired purchased credit impaired loans in August of each year. The above reclassification from nonaccretable to accretable related to the re-estimation of cash flows on the purchased credit impaired loan portfolio, coupled with the loans performing better than expected. The majority of the reclassification related to prepayment speeds decreasing in the residential portfolio, resulting in higher total expected cash flows. 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. Peoples pledges certain loans secured by 1-4 family and multifamily residential mortgages under a blanket collateral agreement to secure borrowings from the FHLB. The amount of such pledged loans totaled $490.1 million and $542.5 million at September 30, 2017 and December 31, 2016 , respectively. Peoples also pledges commercial loans to secure borrowings with the FRB. The outstanding balances of these loans totaled $84.0 million and $152.0 million at September 30, 2017 and December 31, 2016 , 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.

Credit Quality Indicators As discussed in Note 1 of the Notes to the Consolidated Financial Statements included in Peoples' 2016 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 in 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) September 30, 2017 Originated loans: Commercial real estate, construction $ 104,446 $ 5,510 $ 776 $ — $ 455 $ 111,187 Commercial real estate, other 541,073 21,062 11,121 — — 573,256 Commercial real estate 645,519 26,572 11,897 — 455 684,443 Commercial and industrial 382,332 18,943 6,157 — 36 407,468 Residential real estate 18,717 1,033 11,499 182 272,663 304,094 Home equity lines of credit 596 — — — 87,825 88,421 Consumer, indirect 59 9 — — 335,368 335,436 Consumer, other 38 — — — 68,248 68,286 Consumer 97 9 — — 403,616 403,722 Deposit account overdrafts — — — — 507 507 Total originated loans $ 1,047,261 $ 46,557 $ 29,553 $ 182 $ 765,102 $ 1,888,655 Acquired loans: Commercial real estate, construction $ 8,513 $ — $ 52 $ — $ — $ 8,565 Commercial real estate, other 157,610 8,057 8,490 — — 174,157 Commercial real estate 166,123 8,057 8,542 — — 182,722 Commercial and industrial 34,651 220 1,591 — — 36,462 Residential real estate 13,082 604 1,365 — 179,899 194,950 Home equity lines of credit 143 — — — 22,223 22,366 Consumer, indirect 19 — — — 389 408 Consumer, other 42 — — — 1,430 1,472 Consumer 61 — — — 1,819 1,880 Total acquired loans $ 214,060 $ 8,881 $ 11,498 $ — $ 203,941 $ 438,380 Total loans $ 1,261,321 $ 55,438 $ 41,051 $ 182 $ 969,043 $ 2,327,035 Pass Rated (Grades 1 - 4) Special Mention (Grade 5) Substandard (Grade 6) Doubtful (Grade 7) Not Rated Total Loans (Dollars in thousands) December 31, 2016 Originated loans: Commercial real estate, construction $ 73,423 $ — $ 826 $ — $ 10,377 $ 84,626 Commercial real estate, other 505,029 11,855 14,673 — — 531,557 Commercial real estate 578,452 11,855 15,499 — 10,377 616,183 Commercial and industrial 346,791 15,210 16,130 — — 378,131 Residential real estate 47,336 957 12,828 304 246,065 307,490 Home equity lines of credit 465 — 135 — 85,017 85,617 Consumer, indirect 15 13 — — 251,996 252,024 Consumer, other 50 — — — 67,529 67,579 Consumer 65 13 — — 319,525 319,603 Deposit account overdrafts — — — — 1,080 1,080 Total originated loans $ 973,109 $ 28,035 $ 44,592 $ 304 $ 662,064 $ 1,708,104 Acquired loans: Commercial real estate, construction $ 10,046 $ — $ 54 $ — $ — $ 10,100 Commercial real estate, other 181,781 12,475 10,210 — — 204,466 Commercial real estate 191,827 12,475 10,264 — — 214,566 Commercial and industrial 42,809 227 978 194 — 44,208 Residential real estate 17,170 709 1,404 — 209,152 228,435 Home equity lines of credit 202 — — — 25,673 25,875 Consumer, indirect 51 — — — 757 808 Consumer, other 53 — — — 2,887 2,940 Consumer 104 — — — 3,644 3,748 Total acquired loans $ 252,112 $ 13,411 $ 12,646 $ 194 $ 238,469 $ 516,832 Total loans $ 1,225,221 $ 41,446 $ 57,238 $ 498 $ 900,533 $ 2,224,936 In the first nine months of 2017, Peoples' classified loans, which are loans categorized as substandard or doubtful, declined compared to the balances at December 31, 2016 mostly due to loan payoffs.

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 or not a concession has been granted to the borrower. Key factors considered by Peoples include the borrower's ability to access funds at a market rate for 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.

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 nonimpaired 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. During the third quarter of 2017, Peoples completed its reforecast of the estimated cash flows expected to be collected on purchased credit impaired loans.
