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, 2014 (“ 2014 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’ 2014 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 June 30, 2015 , 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 dates indicated. Such adjustments are normal and recurring in nature. All significant intercompany accounts and transactions have been eliminated. The Consolidated Balance Sheet at December 31, 2014 , contained herein has been derived from the audited Consolidated Balance Sheet included in Peoples’ 2014 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 FASB or other standard setting bodies that are adopted by Peoples as of the required effective dates. Unless otherwise discussed, management believes the impact of any recently issued standards, including those issued but not yet effective, will not have a material impact on Peoples' financial statements taken as a whole.

Management reviews the valuation methodology and quality controls utilized by the pricing services in their overall assessment of the reasonableness of the fair values provided, and challenges prices when they believe 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 June 30, 2015 , impaired loans with an aggregate outstanding principal balance of $0.5 million were measured and reported at a fair value of $0.4 million . For the three and six months ended June 30, 2015 , Peoples recognized $130,000 and $167,000 of losses 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’ 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: June 30, 2015 December 31, 2014 (Dollars in thousands) Carrying Amount Fair Value Carrying Amount Fair Value Financial assets: Cash and cash equivalents $ 132,262 $ 132,262 $ 61,454 $ 61,454 Investment securities 822,199 822,342 713,659 713,633 Loans 1,997,983 1,962,441 1,607,391 1,581,813 Financial liabilities: Deposits $ 2,544,572 $ 2,550,034 $ 1,933,074 $ 1,938,021 Short-term borrowings 92,711 92,711 88,277 88,277 Long-term borrowings 128,633 134,188 179,083 183,878 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 much 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). Bank premises and equipment, 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 June 30, 2015 , 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 June 30, 2015 and December 31, 2014 , were largely attributable to changes in market interest rates and spreads since the securities were purchased. At June 30, 2015 , approximately 99% of the mortgage-backed securities 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 three positions, consisted of privately issued mortgage-backed securities with all of the underlying mortgages originated prior to 2004. Two of the three positions had a fair value less than 90% of their book value, with an aggregate book and fair value of $0.8 million and $0.5 million , respectively. Management has 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 three bank-issued trust preferred securities that had been in an unrealized loss position for twelve months or more at June 30, 2015 were primarily attributable to the floating 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 June 30, 2015 . 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.

Receivables [Abstract]
Loans	Loans Peoples' loan portfolio has consisted 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. The major classifications of loan balances, excluding loans held for sale, were as follows: (Dollars in thousands) June 30, December 31, 2014 Originated loans: Commercial real estate, construction $ 50,168 $ 37,901 Commercial real estate, other 449,163 434,660 Commercial real estate 499,331 472,561 Commercial and industrial 256,080 249,975 Residential real estate 263,129 254,169 Home equity lines of credit 67,384 62,463 Consumer 196,306 169,913 Deposit account overdrafts 3,263 2,933 Total originated loans $ 1,285,493 $ 1,212,014 Acquired Loans: Commercial real estate, construction $ 11,220 $ 1,051 Commercial real estate, other 293,369 121,475 Commercial real estate 304,589 122,526 Commercial and industrial 71,013 30,056 Residential real estate 302,639 225,274 Home equity lines of credit 36,607 18,232 Consumer 11,692 12,796 Deposit account overdrafts — — Total acquired loans $ 726,540 $ 408,884 Loans, net of deferred fees and costs $ 2,012,033 $ 1,620,898 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 loans included in the loan balances above are summarized as follows: (Dollars in thousands) June 30, December 31, Commercial real estate, other $ 18,321 $ 7,762 Commercial and industrial 3,538 1,041 Residential real estate 29,145 15,183 Consumer 272 306 Total outstanding balance $ 51,276 $ 24,292 Net carrying amount $ 39,371 $ 19,067 Changes in the accretable yield for the six months ended June 30, 2015 were as follows: (Dollars in thousands) Accretable Yield Balance, December 31, 2014 $ 3,172 Additions: Reclassification from nonaccretable to accretable 2,066 NB&T Financial Group, Inc. 3,622 Accretion (826 ) Balance, June 30, 2015 $ 8,034 Cash flows expected to be collected on acquired impaired loans are estimated semi-annually 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 principal expected to be collected. In reforecasting future estimated cash flows, credit loss expectations are adjusted as necessary. Peoples has pledged 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 $557.2 million and $457.1 million at June 30, 2015 and December 31, 2014 , respectively. Peoples also had pledged commercial loans to secure borrowings with the FRB. The outstanding balances of these loans totaled $135.3 million and $150.7 million at June 30, 2015 and December 31, 2014 , 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) June 30, December 31, June 30, December 31, Originated loans: Commercial real estate, construction $ — $ — $ — $ — Commercial real estate, other 1,912 2,575 — — Commercial real estate 1,912 2,575 — — Commercial and industrial 13,736 1,286 — — Residential real estate 3,266 3,049 101 818 Home equity lines of credit 418 341 — 20 Consumer 53 19 4 2 Total originated loans $ 19,385 $ 7,270 $ 105 $ 840 Acquired loans: Commercial real estate, construction $ — $ 96 $ — $ — Commercial real estate, other 86 9 984 567 Commercial real estate 86 105 984 567 Commercial and industrial 549 708 488 301 Residential real estate 764 304 1,550 1,083 Home equity lines of credit 39 19 17 — Consumer — — 21 8 Total acquired loans $ 1,438 $ 1,136 $ 3,060 $ 1,959 Total loans $ 20,823 $ 8,406 $ 3,165 $ 2,799 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 June 30, 2015 Originated loans: Commercial real estate, construction $ 928 $ — $ — $ 928 $ 49,240 $ 50,168 Commercial real estate, other 8,863 123 822 9,808 439,355 449,163 Commercial real estate 9,791 123 822 10,736 488,595 499,331 Commercial and industrial 4,273 10,000 54 14,327 241,753 256,080 Residential real estate 2,620 648 1,117 4,385 258,744 263,129 Home equity lines of credit 227 47 224 498 66,886 67,384 Consumer 847 220 38 1,105 195,201 196,306 Deposit account overdrafts 23 — — 23 3,240 3,263 Total originated loans $ 17,781 $ 11,038 $ 2,255 $ 31,074 $ 1,254,419 $ 1,285,493 Acquired loans: Commercial real estate, construction $ — $ — $ 69 $ 69 $ 11,151 $ 11,220 Commercial real estate, other 1,472 837 991 3,300 290,069 293,369 Commercial real estate 1,472 837 1,060 3,369 301,220 304,589 Commercial and industrial 227 1,961 937 3,125 67,888 71,013 Residential real estate 1,584 1,258 1,930 4,772 297,867 302,639 Home equity lines of credit 99 23 38 160 36,447 36,607 Consumer 153 14 21 188 11,504 11,692 Deposit account overdrafts — — — — — — Total acquired loans $ 3,535 $ 4,093 $ 3,986 $ 11,614 $ 714,926 $ 726,540 Total loans $ 21,316 $ 15,131 $ 6,241 $ 42,688 $ 1,969,345 $ 2,012,033 December 31, 2014 Originated loans: Commercial real estate, construction $ — $ — $ — $ — $ 37,901 $ 37,901 Commercial real estate, other 565 285 1,220 2,070 432,590 434,660 Commercial real estate 565 285 1,220 2,070 470,491 472,561 Commercial and industrial 17 18 1,245 1,280 248,695 249,975 Residential real estate 4,502 1,062 1,902 7,466 246,703 254,169 Home equity lines of credit 344 425 129 898 61,565 62,463 Consumer 1,136 157 2 1,295 168,618 169,913 Deposit account overdrafts 65 — — 65 2,868 2,933 Total originated loans $ 6,629 $ 1,947 $ 4,498 $ 13,074 $ 1,198,940 $ 1,212,014 Acquired loans: Commercial real estate, construction $ — $ — $ 96 $ 96 $ 955 $ 1,051 Commercial real estate, other 1,067 143 567 1,777 119,698 121,475 Commercial real estate 1,067 143 663 1,873 120,653 122,526 Commercial and industrial 46 6 815 867 29,189 30,056 Residential real estate 4,026 1,331 1,179 6,536 218,738 225,274 Home equity lines of credit 9 19 — 28 18,204 18,232 Consumer 245 27 8 280 12,516 12,796 Deposit account overdrafts — — — — — — Total acquired loans $ 5,393 $ 1,526 $ 2,665 $ 9,584 $ 399,300 $ 408,884 Total loans $ 12,022 $ 3,473 $ 7,163 $ 22,658 $ 1,598,240 $ 1,620,898 Credit Quality Indicators As discussed in Note 1 of the Notes to the Consolidated Financial Statements included in Peoples' 2014 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. “Watch” (grade 5): Loans in this risk grade are the equivalent of the regulatory definition of “Other Assets Especially Mentioned” classification. Loans in this 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 the 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 of 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, its classification as an estimate 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 the 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 Peoples' loan portfolio based upon the most recent analysis performed: Pass Rated (Grades 1 - 4) Watch (Grade 5) Substandard (Grade 6) Doubtful (Grade 7) Not Rated Total Loans (Dollars in thousands) June 30, 2015 Originated loans: Commercial real estate, construction $ 49,726 $ — $ — $ — $ 442 $ 50,168 Commercial real estate, other 431,822 9,260 8,081 — — 449,163 Commercial real estate 481,548 9,260 8,081 — 442 499,331 Commercial and industrial 231,339 7,135 17,605 1 — 256,080 Residential real estate 21,036 1,107 13,694 119 227,173 263,129 Home equity lines of credit 754 — 759 — 65,871 67,384 Consumer 54 — 5 — 196,247 196,306 Deposit account overdrafts — — — — 3,263 3,263 Total originated loans $ 734,731 $ 17,502 $ 40,144 $ 120 $ 492,996 $ 1,285,493 Acquired loans: Commercial real estate, construction $ 11,161 $ — $ — $ — $ 59 $ 11,220 Commercial real estate, other 246,105 18,239 17,458 118 11,449 293,369 Commercial real estate 257,266 18,239 17,458 118 11,508 304,589 Commercial and industrial 58,855 3,812 5,210 342 2,794 71,013 Residential real estate 19,218 2,124 1,144 — 280,153 302,639 Home equity lines of credit 318 — — — 36,289 36,607 Consumer 316 — 1 — 11,375 11,692 Deposit account overdrafts — — — — — — Total acquired loans $ 335,973 $ 24,175 $ 23,813 $ 460 $ 342,119 $ 726,540 Total loans $ 1,070,704 $ 41,677 $ 63,957 $ 580 $ 835,115 $ 2,012,033 December 31, 2014 Originated loans: Commercial real estate, construction $ 37,637 $ — $ — $ — $ 264 $ 37,901 Commercial real estate, other 405,224 12,316 17,120 — — 434,660 Commercial real estate 442,861 12,316 17,120 — 264 472,561 Commercial and industrial 239,168 8,122 2,684 1 — 249,975 Residential real estate 21,296 1,195 11,601 56 220,021 254,169 Home equity lines of credit 767 — 965 — 60,731 62,463 Consumer 60 1 8 — 169,844 169,913 Deposit account overdrafts — — — — 2,933 2,933 Total originated loans $ 704,152 $ 21,634 $ 32,378 $ 57 $ 453,793 $ 1,212,014 Acquired loans: Commercial real estate, construction $ 955 $ — $ — $ — $ 96 $ 1,051 Commercial real estate, other 106,115 7,100 8,260 — — 121,475 Commercial real estate 107,070 7,100 8,260 — 96 122,526 Commercial and industrial 27,313 255 2,294 194 — 30,056 Residential real estate 13,458 833 1,540 — 209,443 225,274 Home equity lines of credit 98 — — — 18,134 18,232 Consumer 279 — — — 12,517 12,796 Deposit account overdrafts — — — — — — Total acquired loans $ 148,218 $ 8,188 $ 12,094 $ 194 $ 240,190 $ 408,884 Total loans $ 852,370 $ 29,822 $ 44,472 $ 251 $ 693,983 $ 1,620,898 Impaired Loans The following table summarizes loans classified as impaired: Unpaid Principal Balance Recorded Investment Total Recorded Investment Average Recorded Investment Interest Income Recognized With Allowance Without Allowance Related Allowance (Dollars in thousands) June 30, 2015 Commercial real estate, construction $ 21,385 $ — $ 21,385 $ 21,385 $ — $ 4,338 $ 389 Commercial real estate, other 11,057 915 9,969 10,884 286 3,039 297 Commercial real estate 32,442 $ 915 $ 31,354 $ 32,269 $ 286 $ 7,377 $ 686 Commercial and industrial 26,267 13,898 9,825 23,723 3,556 5,661 206 Residential real estate 9,252 50 8,399 8,449 6 4,471 182 Home equity lines of credit 313 — 310 310 — 190 6 Consumer 318 — 310 310 — 138 13 Total $ 68,592 $ 14,863 $ 50,198 $ 65,061 $ 3,848 $ 17,837 $ 1,093 December 31, 2014 Commercial real estate, construction $ 9,914 $ — $ 9,909 9,909 $ — $ 2,020 $ 540 Commercial real estate, other 8,668 653 7,742 8,395 189 2,951 248 Commercial real estate 18,582 $ 653 $ 17,651 $ 18,304 $ 189 $ 4,971 $ 788 Commercial and industrial 3,747 1,945 1,767 3,712 816 766 73 Residential real estate 6,889 53 6,372 6,425 9 3,543 272 Home equity lines of credit 500 — 498 498 — 298 18 Consumer 391 — 386 386 — 156 24 Total $ 30,109 $ 2,651 $ 26,674 $ 29,325 $ 1,014 $ 9,734 $ 1,175 At June 30, 2015 , Peoples' impaired loans shown in the table above included loans that were classified as troubled debt restructurings ("TDRs"). 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 debt, such as (i) a reduction in the interest rate for the remaining life of the debt, (ii) an extension of the maturity date at an interest rate lower than the current market rate for new debt 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.

Increases in commercial and industrial, residential real estate, home equity lines of credit and consumer categories of the allowance for loan losses, and related provision for loan losses recorded during 2015 were driven by net charge-off activity and increases in these respective loan portfolios.

On August 4, 2014, the Loan Agreement was amended (as amended, the "Amended Loan Agreement"). Under the Amended Loan Agreement, the interest rate on the term loan was reduced from 3.80% to 3.50% , and certain loan covenants related to the operations of Peoples' business were modified under the Amended Loan Agreement. Peoples is required to make quarterly principal and interest payments until the earlier of either full prepayment by Peoples or the stated maturity date. This note may be prepaid at any time prior to maturity without penalties, so long as no default has occurred. Concurrently, Peoples also entered into a Negative Pledge Agreement that precludes Peoples from selling, transferring, assigning, mortgaging, encumbering, pledging, or entering into a negative pledge agreement with respect to or otherwise disposing of any interest in the capital stock or other ownership interests owned by Peoples in its subsidiaries without prior written approval. Peoples is also subject to certain covenants under the Amended Loan Agreement, which include restrictions on ownership interests of its subsidiaries; cash and cash equivalents; transfers of criticized, classified or nonperforming assets; additional indebtedness; certain material transactions; and other financial covenants which include: • Peoples and Peoples Bank, National Association ("Peoples Bank") must maintain, as of the last day of each fiscal quarter, sufficient capital to qualify as "well capitalized" under applicable regulatory guidance; • Peoples Bank must maintain a "Total Risk-Based Capital Ratio" (as defined in the Loan Agreement) equal to or in excess of 12.50% , measured as of the last day of each fiscal quarter; • Peoples Bank must maintain a ratio of "Nonperforming Assets" to the sum of "Tangible Capital" plus the "Allowance for Loan Losses" (as each term is defined in the Loan Agreement) of not more than 20% , measured as of the last day of each fiscal quarter; • Peoples must maintain a "Fixed Charge Coverage Ratio" (as defined in the Amended Loan Agreement) that equals or exceeds 1.25 to 1.00, commencing with the quarter ended December 31, 2012 and for each quarter thereafter, with the items used in the ratio determined on a trailing 12-month basis; • issuance of dividends from Peoples Bank may not exceed the amount permitted by law without requiring regulatory approval; • minimum liquidity position of $2 million at Peoples; and • Peoples Bank must maintain a ratio of "Allowance for Loan Losses" to "Nonperforming Loans" (as each term is defined in the Amended Loan Agreement) of not less than 70% measured as of the last day of each fiscal quarter. As of June 30, 2015 , Peoples was in compliance with the applicable material covenants imposed by the Amended Loan Agreement. On July 24, 2015, Peoples repaid the term note payable that had an outstanding principal balance of $12.0 million as of June 30, 2015 and the Amended Loan Agreement terminated as of July 24, 2015 as a result. The related Negative Pledge Agreement terminated contemporaneously with the termination of the Amended Loan Agreement. There were no early termination fees associated with the repayment. Peoples' callable national market repurchase agreements consist of agreements with unrelated financial service companies and have original maturities ranging from five to ten years . In general, these agreements may not be terminated by Peoples prior to maturity without incurring additional costs. The callable agreements contain call option features, in which the buyer has the right, at its discretion, to terminate the repurchase agreement after an initial period ranging from three months to five years . After the initial call period, the buyer has a one-time option to terminate the agreement. If the buyer exercises its option, Peoples would be required to repay the agreement in whole at the quarterly date. Peoples is required to make quarterly interest payments. The putable, non-amortizing, fixed rate FHLB advances have original maturities ranging from ten to twenty years that may be repaid prior to maturity, subject to termination fees. The FHLB has the option, solely at its discretion, to terminate the advance after the initial fixed rate periods ranging from three months to five years , 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. These advances require monthly interest payments, with no repayment of principal until the earlier of either an option exercise by the FHLB or the stated maturity. The amortizing, fixed rate FHLB advances have a fixed rate for the term of the loan, 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. During the first quarter of 2015, Peoples repaid several FHLB advances including putable, non-amortizing, fixed rate advances and amortizing, fixed-rate advances, totaling approximately $52.1 million that resulted in early termination fees of $520,000 , and had a weighted-average cost of 1.49% . On March 6, 2015, Peoples completed its acquisition of NB&T Financial Group, Inc. ("NB&T"), which included the assumption of Fixed/Floating Rate Junior Subordinated Debt Securities due 2037 (the "junior subordinated debt securities") at an acquisition-date fair value of $6.6 million held in a wholly-owned statutory trust whose common securities were wholly-owned by NB&T. The sole assets of the statutory trust are the junior subordinated debt securities and related payments. The junior subordinated debt securities and the back-up obligations, in the aggregate, constitute a full and unconditional guarantee of the obligations of the statutory trust under the Capital Securities held by third-party investors. Distributions on the Capital Securities are payable at the annual rate of 1.50% over the 3-month LIBOR. Distributions on the Capital Securities are included in interest expense in the Unaudited Consolidated Financial Statements. These securities are considered Tier I capital (with certain limitations applicable) under current regulatory guidelines. The junior subordinated debt securities are subject to mandatory redemption, in whole or in part, upon repayment of the Capital Securities at maturity or their earlier redemption at the liquidation amount. Subject to prior approval of the Federal Reserve, the Capital Securities are redeemable prior to the maturity date of September 6, 2037, and are redeemable at par. Distributions on the Capital Securities can be deferred from time to time for a period not to exceed 20 consecutive semi-annual periods. The aggregate minimum annual retirements of long-term borrowings in future periods are as follows: (Dollars in thousands) Balance Weighted-Average Rate Six Months Ending December 31, 2015 $ 5,377 2.78 % Year Ending December 31, 2016 7,734 3.07 % Year Ending December 31, 2017 7,126 3.16 % Year Ending December 31, 2018 42,390 3.33 % Year Ending December 31, 2019 41,426 3.59 % Thereafter 24,580 2.69 % Total long-term borrowings $ 128,633 3.24 %

Compensation and Retirement Disclosure [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 pay 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 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 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 Six Months Ended June 30, June 30, (Dollars in thousands) 2015 2014 2015 2014 Interest cost $ 109 $ 131 $ 224 $ 274 Expected return on plan assets (121 ) (150 ) (251 ) (319 ) Amortization of net loss 31 36 64 69 Settlement of benefit obligation 103 536 372 1,022 Net periodic cost $ 122 $ 553 $ 409 $ 1,046 Postretirement Benefits Three Months Ended Six Months Ended June 30, June 30, (Dollars in thousands) 2015 2014 2015 2014 Interest cost $ 1 $ 2 $ 2 $ 3 Amortization of net gain (1 ) (2 ) (2 ) (4 ) Net periodic benefit $ — $ — $ — $ (1 ) Under US GAAP, Peoples is required to recognize a settlement gain or loss when the aggregate amount of lump-sum distributions to participants equals or exceeds the sum of the service and interest cost components of the net periodic pension cost. The amount of settlement gain or loss recognized is the pro rata amount of the unrealized gain or loss existing immediately prior to the settlement. In general, both the projected benefit obligation and the fair value of plan assets are required to be remeasured in order to determine the settlement gain or loss. In the six months of 2015, the total lump-sum distributions made to participants caused the total settlements to exceed the recognition threshold for settlement gains or losses. As a result, Peoples remeasured its pension obligation and plan assets as of April 1, 2015 as part of the calculation of the settlement loss recognized. The following table summarizes the change in pension obligation and funded status as a result of this remeasurement and the aggregate settlement for the three months ended June 30, 2015 : As of June 30, 2015 (Dollars in thousands) December 31, Before Settlement Impact of Settlements After Settlements Funded status: 2014 Projected benefit obligation $ 13,695 $ 12,695 $ (258 ) $ 12,437 Fair value of plan assets 8,259 7,794 (258 ) 7,536 Funded status $ (5,436 ) $ (4,901 ) $ — $ (4,901 ) Gross unrealized loss (gain) $ 5,979 $ 5,139 $ (103 ) $ 5,036 Assumptions: Discount rate 3.50 % 3.70 % 3.70 % Expected return on plan assets 7.50 % 7.50 % 7.50 %

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 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 February 2007, Peoples has granted a combination of restricted common shares and stock appreciation rights (“SARs”) to be settled in 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 Options Under the provisions of the 2006 Equity Plan and predecessor stock option plans, the exercise price per share of any stock option granted may not be less than the grant date fair market value of the underlying common shares. All stock options granted to both employees and non-employee directors expire ten years from the date of grant. The most recent stock option grants to employees and non-employee directors occurred in 2006. The stock options granted to employees vested three years after the grant date, while the stock options granted to non-employee directors vested six months after the grant date. The following table summarizes the changes to Peoples' stock options for the six months ended June 30, 2015 : Number of Common Shares Subject to Options Weighted-Average Exercise Price Weighted-Average Remaining Contractual Life Aggregate Intrinsic Value Outstanding at January 1 38,577 $ 28.09 Expired 14,880 27.04 Outstanding at June 30 23,697 $ 28.75 0.7 $ — Exercisable at June 30 23,697 $ 28.75 0.7 $ — The following table summarizes Peoples’ stock options outstanding at June 30, 2015 : Options Outstanding & Exercisable Range of Exercise Prices Common Shares Subject to Options Outstanding & Exercisable Weighted-Average Remaining Contractual Life Weighted-Average Exercise Price $28.25 13,697 0.6 years 28.25 $28.56 to $30.00 10,000 0.9 years 29.43 Total 23,697 0.7 years $ 28.75 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 grant date and are to expire ten years from the date of grant. The most recent grant of SARs occurred in 2008.

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 quarter of 2015, Peoples granted 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, 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.

Business Combinations [Abstract]
Acquisitions	Acquisitions On March 6, 2015, Peoples completed its acquisition of NB&T for total consideration of $102.7 million which reflected the conversion of each of the 3,442,329 outstanding NB&T common shares into $7.75 in cash and 0.9319 in Peoples' common shares. NB&T merged into Peoples and NB&T's wholly-owned subsidiary, The National Bank and Trust Company, which operates 22 full-service branches in southwest Ohio, merged into Peoples Bank. The acquisition was accounted for as a business combination under the acquisition method of accounting under US GAAP. The assets purchased, liabilities assumed, and related identifiable intangible assets were recorded at their acquisition date fair values. Per the applicable accounting guidance for business combinations, these fair values are preliminary and subject to refinement for up to one year after the closing date of the acquisition as additional information relative to closing date fair values becomes available. The goodwill recognized will not be deductible for income tax purposes. As a result of the NB&T acquisition, Peoples acquired loans of $384.9 million and deposits of $629.5 million after preliminary acquisition accounting adjustments. The balances and operations related to the acquisition are included in Peoples' Unaudited Consolidated Financial Statements from the date of the acquisition. The following table is a preliminary summary of changes in goodwill and intangible assets during the preliminary purchase price calculation as of the date of acquisition for NB&T, and the assets acquired and liabilities assumed at their estimated fair values. (Dollars in thousands, except per share data) NB&T Purchase Price Common shares outstanding of acquired company at acquisition date 3,442,329 Cash purchase price per share $ 7.75 Cash consideration 26,678 Number of common shares of Peoples issued for each common share of acquired company 0.9319 Price per Peoples common share, based on closing stock price on acquisition date $ 23.70 Common share consideration 76,027 Total purchase price $ 102,705 Net Assets at Fair Value Assets Cash and cash equivalents $ 124,825 Investment securities 156,392 Loans, including loans held for sale, net of deferred fees and costs 384,859 Bank premises and equipment, net 10,702 Other intangible assets 10,130 Other assets 24,181 Total assets 711,089 Liabilities Deposits 629,512 Borrowings 6,570 Accrued expenses and other liabilities 5,992 Total liabilities 642,074 Net assets $ 69,015 Goodwill $ 33,690 The estimated fair values presented in the above table reflect additional information that was obtained during the three months ended June 30, 2015, which resulted in changes to certain fair value estimates made as of the date of acquisition. Material adjustments to acquisition date estimated fair values are recorded in the period in which the acquisition occurred and, as a result, previously recorded results have changed. After considering this additional information, the cash acquired decreased $5.4 million , the estimated fair value of loans decreased $5.1 million , the intangible assets acquired increased $1.3 million , the other assets increased $0.1 million , and the estimated fair value of accrued expenses and other liabilities decreased $1.6 million as of the date of acquisition from that originally reported in the three months ended March 31, 2015. The change in accrued expenses and other liabilities was mainly due to a decrease in the net deferred tax asset of $1.2 million as a result of these revised fair values. These revised fair value estimates resulted in a net increase to goodwill of $7.6 million from that originally reported for the three months ended March 31, 2015 to $33.7 million , which is recognized in the June 30, 2015 consolidated balance sheet. Acquired loans are reported net of the unamortized fair value adjustment. The following table details the preliminary fair value adjustment for acquired loans as of the acquisition date: (Dollars in thousands, except per share data) NB&T Nonimpaired Loans Contractual cash flows $ 497,451 Nonaccretable difference 45,830 Expected cash flows 451,621 Accretable yield 90,346 Fair value $ 361,275 Purchase Credit Impaired Loans Contractual cash flows $ 40,259 Nonaccretable difference 13,053 Expected cash flows 27,206 Accretable yield 3,622 Fair value $ 23,584 Peoples recorded non-interest expenses related to acquisitions, mainly the NB&T acquisition, of $9.7 million and net losses on asset disposals related to the NB&T acquisition of $0.6 million in the Consolidated Statement of Income for the six months ended June 30, 2015. The $9.7 million was included in the following line items on the Consolidated Statement of Income for the six months ended June 30, 2015, salaries and employee benefit costs contained $4.4 million , professional fees contained $1.7 million , and other non-interest expenses contained $3.6 million .
