Summary of Significant Accounting Policies	'
	Summary of Significant Accounting Policies
	The accounting and reporting policies of Peoples Bancorp Inc. and 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.) conform to generally accepted accounting principles in the United States of America (“US GAAP”) and to general practices within the banking industry. The preparation of the financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Certain items in prior financial statements have been reclassified to conform to the current presentation, which had no impact on net income, comprehensive income or loss, net cash provided by operating activities or stockholders' equity.
	The following is a summary of significant accounting policies followed in the preparation of the financial statements:
	Consolidation: Peoples' Consolidated Financial Statements include subsidiaries in which Peoples has a controlling financial interest, principally defined as owning a voting interest greater than 50%. In addition, entities not controlled by voting interest or in which the equity investors do not bear the residual economic risks, but for which Peoples is the primary beneficiary are also consolidated.
	The Consolidated Financial Statements include the accounts of Peoples and its consolidated subsidiaries, Peoples Bank and Peoples Investment Company, along with their wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.
	Cash and Cash Equivalents: Cash and cash equivalents include cash on hand, balances due from other banks, interest-bearing deposits in other banks, Federal Funds sold and other short-term investments with original maturities of ninety days or less. Included in interest-bearing deposits in other banks were $3.0 million in funds at both December 31, 2013 and 2012, which were being used as collateral and not available for withdrawal.
	Investment Securities: Investment securities are recorded initially at cost, which includes premiums and discounts if purchased at other than par or face value. Peoples amortizes premiums and accretes discounts as an adjustment to interest income on a level yield basis. The cost of investment securities sold, and any resulting gain or loss, is based on the specific identification method and recognized as of the trade date.
	Management determines the appropriate classification of investment securities at the time of purchase. Held-to-maturity securities are those securities that Peoples has the positive intent and ability to hold to maturity and are recorded at amortized cost. Available-for-sale securities are those securities that would be available to be sold in the future in response to Peoples' liquidity needs, changes in market interest rates, and asset-liability management strategies, among other considerations. Available-for-sale securities are reported at fair value, with unrealized holding gains and losses reported in stockholders' equity as a separate component of other comprehensive income or loss, net of applicable deferred income taxes.
	Certain restricted equity securities that do not have readily determinable fair values and for which Peoples does not exercise significant influence, are carried at cost. These cost method securities are reported as other investment securities on the Consolidated Balance Sheets and consist solely of shares of the Federal Home Loan Bank of Cincinnati (the “FHLB”), the Federal Reserve Bank of Cleveland (the "FRB") and a capital investment in West Virginia Bankers Insurance.
	Management systematically evaluates investment securities for other-than-temporary declines in fair value on a quarterly basis. This analysis requires management to consider various factors, which include (1) the duration and magnitude of the decline in value, (2) the financial condition of the issuer or issuers and (3) the structure of the security.
	An impairment loss is recognized in earnings only when (1) Peoples intends to sell the debt security; (2) it is more likely than not that Peoples will be required to sell the security before recovery of its amortized cost basis or (3) Peoples does not expect to recover the entire amortized cost basis of the security. In situations where Peoples intends to sell or when it is more likely than not that Peoples will be required to sell the security, the entire impairment loss must be recognized in earnings. In all other situations, only the portion of the impairment loss representing the credit loss must be recognized in earnings, with the remaining portion being recognized in stockholders' equity as a component of accumulated comprehensive income, net of deferred taxes.
	Fair Value Measurements: The measurement of fair value under US GAAP uses a hierarchy intended to maximize the use of observable inputs and minimize the use of unobservable inputs.  This hierarchy uses three levels of inputs to measure the fair value of assets and liabilities as follows:
	Level 1: Quoted prices in active exchange markets for identical assets or liabilities; also includes certain U.S. Treasury and other U.S. government and agency securities actively traded in over-the-counter markets.
	Level 2: Observable inputs other than Level 1 including quoted prices for similar assets or liabilities, quoted prices in less active markets, or other observable inputs that can be corroborated by observable market data; also includes derivative contracts whose value is determined using a pricing model with observable market inputs or can be derived principally from or corroborated by observable market data.  This category generally includes certain U.S. government and agency securities, corporate debt securities, derivative instruments, and residential mortgage loans held for sale.
	Level 3: Unobservable inputs supported by little or no market activity for financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation; also includes observable inputs for single dealer nonbinding quotes not corroborated by observable market data. This category generally includes certain private equity investments, retained interests from securitizations, and certain collateralized debt obligations.
	Securities Sold Under Agreements to Repurchase: Peoples enters into sales of securities under agreements to repurchase (“Repurchase Agreements”) with customers and other financial service companies, which are considered financings. As such, these obligations are recorded as a liability on the Consolidated Balance Sheets and disclosed in Notes 9 and 10. Securities pledged as collateral under Repurchase Agreements are included in investment securities on the Consolidated Balance Sheets and are disclosed in Note 3. The fair value of the collateral pledged to a third party is continually monitored and additional collateral is pledged or returned, as deemed appropriate.
	Loans: Loans originated that Peoples has the positive intent and ability to hold for the foreseeable future or to maturity or payoff are reported at the principal balance outstanding, net of deferred loan fees and costs and an allowance for loan losses. The foreseeable future is based upon current market conditions and business strategies, as well as balance sheet management and liquidity. As the conditions change, so may management's view of the foreseeable future. Net deferred loan costs were $2.3 million and $1.5 million at December 31, 2013 and 2012, respectively.
	A loan is considered impaired when information and events indicate it is probable that collection of all contractual principal and interest payments is doubtful. Impairment is evaluated in total for smaller-balance loans of a similar nature, primarily consumer and residential real estate loans, and on an individual loan basis for all loans to borrowers with an aggregate unpaid principal balances in excess of $1 million. Peoples typically places any loan deemed to be impaired on nonaccrual status and allocates a specific portion of the allowance for loan losses, if necessary, to reduce the net carrying value of the loan to its estimated net realizable value. Impaired loans, or portions thereof, are charged off when deemed uncollectible. Upon detection of the reduced ability of a borrower to meet cash flow obligations, consumer and residential real estate loans typically are charged down to the net realizable value, with the residual balance placed on nonaccrual status.
	Loans acquired in a business combination that have evidence of deterioration of credit quality since origination and for which it is probable, at acquisition, that Peoples will be unable to collect all contractually required payments receivable are initially recorded at fair value (the present value of the amounts expected to be collected) with no valuation allowance. The difference between the undiscounted cash flows expected at acquisition and the investment in the loan is recognized as interest income on a level-yield method over the life of the loan. Contractually required payments for interest and principal that exceed the undiscounted cash flows expected at acquisition are not recognized.
	Over the life of these acquired loans, management continues to monitor each acquired loan portfolio for changes in credit quality. Increases in expected cash flows subsequent to acquisition are recognized prospectively over their remaining life as a yield adjustment on the loans. Subsequent decreases in expected cash flows are recognized as impairment, with the amount of the expected loss included in management's evaluation of the adequacy of the allowance for loan losses.
	Loans Held-for-Sale: Loans originated and intended to be sold in the secondary market, generally one-to-four family residential loans, are carried at the lower of cost or estimated fair value determined on an aggregate basis. Gains and losses on sales of loans held for sale are included in mortgage banking income.
	Loans originated with the intent to be held in our portfolio are subsequently transferred to held-for-sale when a decision is made to sell these loans. At the time of a loan's transfer to the held-for-sale classification, the loan is recorded at the lower of cost or its fair value. Any reduction in the loan's value is reflected as a write-down of the recorded investment resulting in a new cost basis, with a corresponding charge against the allowance for loan losses. If the fair value of a loan classified as held-for-sale in subsequent periods is less than its cost basis, the carrying value of the loan is adjusted accordingly, with the corresponding loss recognized in earnings.
	Peoples enters into interest rate lock commitments with borrowers and best efforts commitments with investors on loans originated for sale into the secondary markets to manage the inherent interest rate and pricing risk associated with selling loans. The interest rate lock commitments generally terminate once the loan is funded, the lock period expires or the borrower decides not to contract for the loan. The best efforts commitments generally terminate once the loan is sold, the commitment period expires or the borrower decides not to contract for the loan. These commitments are considered derivatives which are generally accounted for by recognizing their estimated fair value on the Consolidated Balance Sheets as either a freestanding asset or liability. The valuation of such commitments does not consider expected cash flows related to the servicing of the future loan. Management has determined these derivatives do not have a material effect on Peoples' financial position, results of operations or cash flows.
	Allowance for Loan Losses: The allowance for loan losses is a valuation reserve established through provisions for loan losses charged against income. The allowance for loan losses is maintained at a level that management deems sufficient to absorb probable losses inherent in the loan portfolio. Loans deemed to be uncollectible are charged against the allowance for loan losses, while recoveries of previously charged-off amounts are credited to the allowance for loan losses.
	The allowance for loan losses is comprised of specific valuation allowances for loans evaluated individually for impairment and general allocations for pools of homogeneous loans with similar risk characteristics and trends. Peoples' homogenous loan pools include similarly risk-graded commercial and industrial loans, similarly risk-graded commercial real estate loans, real estate construction loans (both commercial and residential), residential real estate loans, consumer home equity loans and other consumer loans. Management's evaluation of the adequacy of the allowance for loan losses and the appropriate provision for loan losses is based upon a quarterly analysis of the portfolio. While portions of the allowance for loan losses may be allocated to specific loans; the entire allowance for loan losses is available for any loan charged off by management.
	The allowance for loan losses related to specific loans is based on management's estimate of potential losses on impaired loans as determined by (1) the present value of expected future cash flows; (2) the fair value of collateral if the loan is determined to be collateral dependent or (3) the loan's observable market price. The general allocations to specific loan pools are based on the historical loss rates for specific loan types and the internal risk grade, if applicable, adjusted for both internal and external qualitative risk factors. The calculation of historical loss ratios for pools of similar loans with similar characteristics is based upon the proportion of actual charge-offs experienced to the total population of loans in the pool. The historical loss ratios are periodically updated based on actual charge-off experience. The qualitative factors considered by management include, among other factors, (1) changes in local and national economic conditions; (2) changes in asset quality; (3) changes in loan portfolio volume; (4) the composition and concentrations of credit; (5) the impact of competition on loan structuring and pricing; (6) the impact of interest rate changes on portfolio risk and (7) effectiveness of Peoples' loan policies, procedures and internal controls. The total allowance established for each homogenous loan pool represents the product of the historical loss ratio and the total dollar amount of the loans in the pool.
	Peoples categorizes loans involving commercial borrowers into risk categories based upon an established grading matrix. This system is used to manage the risk within its commercial lending activities, evaluate changes in the overall credit quality of the loan portfolio and evaluate the adequacy of the allowance for loan losses. Loan grades are assigned at the time a new loan or lending commitment is extended by Peoples and may be changed at any time when circumstances warrant. Peoples reviews, at least annually, all loan relationships with aggregate outstanding debt to Peoples of $1,000,000 or more, with adversely classified loans generally reviewed on a quarterly basis.
	The primary factors considered when assigning a risk grade to a loan include (1) reliability and sustainability of the primary source of repayment; (2) past, present and projected financial condition of the borrower and (3) current economic and industry conditions. Other factors that could influence the risk grade assigned include the type and quality of collateral and strength of guarantors. The primary source of repayment for commercial real estate loans and commercial and industrial loans is normally the business's operating cash flow available to repay debt. Management's analysis of operating cash flow for commercial real estate loans secured by non-owner occupied properties takes into account factors such as rent rolls and vacancy statistics. Management's analysis of operating cash flow for commercial real estate loans secured by owner occupied properties and all commercial and industrial loans considers the profitability, liquidity and leverage of the business. The evaluation of construction loans is based largely on the borrower's ability to complete construction within the established budget.
	The primary factors considered when classifying consumer loans include the loan's past due status and declaration of bankruptcy by the borrower(s). The classification of residential real estate and home equity lines of credit also takes into account the current value of the underlying collateral.
	Troubled Debt Restructuring: The restructuring of a loan is considered a troubled debt restructuring ("TDR") if both (i) the borrower is experiencing financial difficulties and (ii) the creditor has granted a concession.
	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 debtor is currently in payment default on any of its debt; (ii) a payment default is probable in the foreseeable future without the modification; (iii) the debtor has declared or is in the process of declaring bankruptcy and (iv) the debtor'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 debtor'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. All TDRs are considered impaired loans and are evaluated individually to determine if a write-down is required and if they should be on accrual or nonaccrual status.
	Bank Premises and Equipment: Bank premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed on the straight-line method over the estimated useful lives of the related assets owned. Major improvements to leased facilities are capitalized and included in bank premises at cost less accumulated depreciation, which is calculated on the straight-line method over the lesser of the remaining term of the leased facility or the estimated economic life of the improvement.
	Bank Owned Life Insurance: Bank owned life insurance (“BOLI”) represents life insurance on the lives of certain employees who have provided positive consent allowing Peoples Bank to be the beneficiary of such policies. These policies are recorded at their cash surrender value, or the amount that can be realized upon surrender of the policies. Income from these policies and changes in the cash surrender value are recorded in other income.
	Investments in Affordable Housing Limited Partnerships: Investments in affordable housing consist of investments in limited partnerships that operate qualified affordable housing projects or that invest in other limited partnerships formed to operate affordable housing projects. These investments are considered variable interest entities for which Peoples is not the primary beneficiary. Peoples generally utilizes the effective yield method to account for these investments with the tax credits, net of the amortization of the investment, reflected in the Consolidated Statements of Income as a reduction of income tax expense. The unamortized amount of the investments is recorded in other assets and totaled $0.3 million and $0.8 million at December 31, 2013 and 2012, respectively.
	Other Real Estate Owned: Other real estate owned (“OREO”), included in other assets on the Consolidated Balance Sheets, is comprised primarily of commercial and residential real estate properties acquired by Peoples Bank in satisfaction of a loan. OREO obtained in satisfaction of a loan is recorded at the lower of cost or estimated fair value, less estimated costs to sell the property. Peoples had OREO totaling $0.9 million at December 31, 2013, and $0.8 million at December 31, 2012.
	Goodwill and Other Intangible Assets: Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired in the business combination. Goodwill is not amortized but is tested for impairment at least annually and updated quarterly if necessary. Based upon the most recently completed goodwill impairment test, Peoples concluded the recorded value of goodwill was not impaired as of December 31, 2013, based upon the estimated fair value of Peoples' single reporting unit.
	Peoples' other intangible assets consist of customer relationship intangible assets representing the present value of future net income to be earned from acquired customer relationships with definite useful lives. These intangible assets are amortized on an accelerated basis over their estimated lives ranging from 7 to 10 years.
	Servicing Rights: Servicing rights (“SRs”) represent the right to service loans sold to third-party investors. SRs are recognized separately as a servicing asset or liability whenever Peoples undertakes an obligation to service financial assets. SRs are reported in other intangible assets on the Consolidated Balance Sheets. Serviced loans are not included in the Consolidated Balance Sheets. Loan servicing income included in mortgage banking income includes servicing fees received from the third-party investors and certain charges collected from the borrowers.
	Peoples initially records SRs at fair value at the time of the sale of the loans to the third-party investor. Peoples follows the amortization method for the subsequent measurement of each class of separately recognized servicing assets and liabilities. Under the amortization method, Peoples amortizes the value of servicing assets or liabilities in proportion to and over the period of estimated net servicing income or net servicing loss and assesses servicing assets or liabilities for impairment or increased obligation based on fair value at each reporting date. The fair value of the SRs is determined by using a discounted cash flow model, which estimates the present value of the future net cash flows of the servicing portfolio based on various factors, such as servicing costs, expected prepayment speeds and discount rates.
	Preferred Stock and Common Stock Warrant: As more fully described in Note 11, Peoples issued preferred stock and a common stock warrant, subsequently redeemed in 2011 and 2012, respectively, that were classified in stockholders' equity on the Consolidated Balance Sheets. The preferred stock had similar characteristics of an “Increasing Rate Security” as described by Securities and Exchange Commission (“SEC”) Staff Accounting Bulletin Topic 5Q, Increasing Rate Preferred Stock. The proceeds received in conjunction with the issuance of the preferred stock and common stock warrant were allocated to the preferred stock and common stock warrant based on their relative fair values. Discounts on the increasing rate preferred stock were amortized over the expected life of the preferred stock (5 years), by charging imputed dividend cost against retained earnings and increasing the carrying amount of the preferred stock by a corresponding amount. The discount at the time of issuance was computed as the present value of the difference between dividends that would be payable in future periods and the dividend amount for a corresponding number of periods, discounted at a market rate for dividend yield on comparable securities. The amortization in each period was the amount which, together with the stated dividend in the period, resulted in a constant rate of effective cost with regard to the carrying amount of the preferred stock.
	Common stock warrants are evaluated for liability or equity treatment. The common stock warrant issued by Peoples was carried in stockholders' equity until repurchased based on the view of both the SEC and Financial Accounting Standards Board (the “FASB”) that they would not object to classification of such form of common stock warrant as permanent equity. This view is consistent with the objective of the Capital Purchase Program that the equity represented by these securities should be considered part of equity for regulatory reporting purposes. The fair value of the common stock warrant used in allocating total proceeds received was determined based on a binomial model.
	Trust Assets Under Management: Peoples Bank manages certain assets held in a fiduciary or agency capacity for customers. These assets under management, other than cash on deposit at Peoples Bank, are not included in the Consolidated Balance Sheets since they are not assets of Peoples Bank.
	Interest Income Recognition: Interest income on loans and investment securities is recognized by methods that result in level rates of return on principal amounts outstanding. Amortization of premiums has been deducted from, and accretion of discounts has been added to, the related interest income. Nonrefundable loan fees and direct loan costs are deferred and recognized over the life of the loan as an adjustment of the yield.
	Peoples discontinues the accrual of interest on all loans, whether or not such loans are considered past due, when management believes it is probable the borrower will be unable to meet its payment obligations as they become due, as well as when required by regulatory provisions. When interest accrual is discontinued, all unpaid accrued interest is reversed. Interest received on nonaccrual loans is included in income only if principal recovery is reasonably assured. A nonaccrual loan is restored to accrual status when it is brought current, has performed in accordance with contractual terms for a reasonable period of time, and the collectibility of the total contractual principal and interest is no longer in doubt.
	Other Income Recognition: Service charges on deposits include cost recovery fees associated with services provided, such as overdraft and non-sufficient funds. Trust and investment income consists of revenue from fiduciary activities, which include fees for services such as asset management, recordkeeping, retirement services and estate management, and investment commissions and fees related to the sale of investments. Income from these activities is recognized at the time the related services are performed.
	Insurance income consists of commissions and fees from the sales of insurance policies and related insurance services. Insurance commission income is recognized as of the effective date of the insurance policy, net of adjustments, including policy cancellations. Such adjustments are recorded when the amount can be reasonably estimated, which is generally in the period in which they occur. Contingent performance-based commissions from insurance companies are recognized when received and no contingencies remain.
	Income Taxes: Peoples and its subsidiaries file a consolidated federal income tax return. Deferred income tax assets and liabilities are provided for temporary differences between the tax basis of an asset or liability and its reported amount in the Consolidated Financial Statements at the statutory Federal tax rate. A valuation allowance, if needed, reduces deferred tax assets to the expected amount most likely to be realized. Realization of deferred tax assets is dependent upon the generation of a sufficient level of future taxable income and recoverable taxes paid in prior years. The components of other comprehensive income or loss included in the Consolidated Statements of Stockholders' Equity have been computed based upon a 35% Federal tax rate.
	A tax position is initially recognized in the financial statements when it is more likely than not the position will be sustained upon examination by the tax authorities. Such tax positions are initially and subsequently measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement with the tax authority assuming full knowledge of the position and all relevant facts. Penalties and interest incurred under the applicable tax law are classified as income tax expense. The amount of Peoples' uncertain income tax positions, unrecognized benefits and accrued interest were immaterial at both December 31, 2013 and 2012.
	Advertising Costs: Advertising costs are generally expensed as incurred.
	Earnings per Share: Basic and diluted earnings per common share (“EPS”) are calculated using the two-class method since Peoples has issued share-based payment awards considered participating securities because they entitle holders to non-forfeitable rights to dividends during the vesting term. The two-class method is an earnings allocation formula that determines net income per share for each class of common stock and participating security according to dividends declared and participation rights in undistributed earnings. Basic earnings per common share is computed by dividing net earnings allocated to common shareholders by the weighted-average number of common shares outstanding.  Diluted earnings per common share is computed by dividing net earnings allocated to common shareholders by the weighted-average number of common shares outstanding adjusted to include the effect of potentially dilutive common shares.  Potentially dilutive common shares include incremental common shares issuable upon exercise of outstanding stock options, SARs and non-vested restricted common shares using the treasury stock method.
	Operating Segments: Peoples' business activities are currently confined to one reporting unit and reportable segment, which is community banking. As a community banking entity, Peoples offers its customers a full range of products including a complete line of banking, investment, insurance and trust solutions.
	Stock-Based Compensation: Compensation costs for stock options, restricted stock awards and stock appreciation rights are measured at the fair value of these awards on their grant date. Compensation expense is recognized over the required service period, generally the vesting period for stock options and stock appreciation rights and the restriction period for restricted stock awards. For all awards, only the expense for the portion of the awards expected to vest is recognized. For service-based awards, compensation expense for awards granted to employees who are eligible for retirement is recognized to the date the employee is first eligible to retire.
	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.
	In February 2013, the Financial Accounting Standards Board issued an accounting standards update with new guidance on the presentation of accumulated other comprehensive income (“AOCI”). This standard was effective for public companies for interim and annual periods beginning after December 15, 2012. The amendment requires an entity to present the reclassification adjustments out of AOCI and into net income for each component reported. These amounts may be disclosed before-tax or after-tax, and must be disclosed in either the income statement or the notes to the financial statements. This update is intended to supplement changes made in 2012 to increase the prominence of items reported in other comprehensive income. Peoples adopted this new guidance on January 1, 2013, as required. As a result of the adoption, the disclosure of AOCI included in Note 11 contains additional information regarding reclassifications out of AOCI and into net income.
	In January 2014, the Financial Accounting Standards Board issued an accounting standards update allowing entities to make an accounting policy election with respect to using the proportional amortization method for investments in qualified affordable housing projects, if certain conditions are met. This standard will be effective for public companies for interim and annual periods beginning after December 15, 2014. Peoples will adopt this new guidance as required, and it is not expected to have a material impact on Peoples’ Consolidated Financial Statements.
	Also in January 2014, the Financial Accounting Standards Board issued an accounting standards update clarifying guidance for in substance reposessions and foreclosures, and requiring additional disclosures regarding foreclosed residential real estate property and recorded investments in consumer mortgage loans collateralized by residential real estate in the process of foreclosure. This standard will be effective for public companies for interim and annual periods beginning after December 15, 2014. Peoples will adopt this new guidance as required, and it is not expected to have a material impact on Peoples’ Consolidated Financial Statements.

	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 volatilities, LIBOR yield curves, credit spreads and prices from market makers and live trading systems (Level 2). The available-for-sale securities' fair values of the states and political subdivisions measured at fair value using Level 1 inputs at December 31, 2012 represented the purchase price of the securities since they were acquired near year-end 2012. At December 31, 2013, these securities were classified as Level 2 as a pricing model was used to value the securities, which was consistent with the classification of the rest of the sector.
	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 December 31, 2013, impaired loans with an aggregate outstanding principal balance of $2.4 million were measured and reported at a fair value of $1.4 million.  For the year ended December 31, 2013, Peoples recognized losses of $0.9 million on impaired loans 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:
		2013					2012
	(Dollars in thousands)	Carrying Amount		Fair Value			Carrying Amount			Fair Value
	Financial assets:
	Cash and cash equivalents	$	53,820	$	53,820		$	62,542		$	62,542
	Investment securities	680,526		677,398			709,085			710,934
	Loans	1,180,857		1,165,560			973,907			897,132
	Financial liabilities:
	Deposits	$	1,580,758	$	1,587,448		$	1,492,303		$	1,503,098
	Short-term borrowings	113,590		113,590			47,769			47,769
	Long-term borrowings	121,826		128,205			128,823			141,691
	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 short-term 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 2 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 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.

	Management systematically evaluates available-for-sale investment securities for other-than-temporary declines in fair value on a quarterly basis. At December 31, 2013, 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 December 31, 2013 and December 31, 2012, were attributable to changes in market interest rates and spreads since the securities were purchased.
	At December 31, 2013, approximately 96% 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 4%, or five positions, consisted of privately issued mortgage-backed securities with all of the underlying mortgages originated prior to 2004. Three of the five positions had a fair value less than 90% of their book value, with an aggregate book and fair value of $1.8 million and $1.6 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 four bank-issued trust preferred securities that had been in an unrealized loss position for twelve months or more at December 31, 2013 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 weighted-average yield of available-for-sale securities by contractual maturity at December 31, 2013.  The 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.

	Loans
	Peoples' loan portfolio consists of various types of loans originated primarily as a result of lending opportunities within Peoples' primary market areas of central, northeastern and southeastern Ohio, west central West Virginia, and northeastern Kentucky. The major classifications of loan balances, excluding loans held for sale, were as follows:
	(Dollars in thousands)	2013			2012
	Commercial real estate, construction	$	47,539		$	34,265
	Commercial real estate, other	450,170			378,073
	Commercial real estate	497,709			412,338
	Commercial and industrial	232,754			180,131
	Residential real estate	268,617			233,841
	Home equity lines of credit	60,076			51,053
	Consumer	135,018			101,246
	Deposit account overdrafts	2,060			6,563
	Total loans	$	1,196,234		$	985,172
	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, commonly referred to as "purchase credit impaired" loans. During 2013, Peoples determined that some loans which had originally been classified as purchased credit impaired did not have evidence of deterioration of credit quality on acquisition. As a result, the carrying amounts of loans considered purchased credit impaired have decreased and amounts reported in the following table are reflective of this change. The carrying amounts of these loans included in the loan balances above are summarized as follows:
	(Dollars in thousands)	2013			2012
	Commercial real estate	$	963		$	39
	Commercial and industrial	78			—
	Residential real estate	1,236			1,524
	Consumer	—			8
	Total outstanding balance	$	2,277		$	1,571
	Net carrying amount	$	1,875		$	1,095
	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 $259.1 million and $202.0 million at December 31, 2013 and December 31, 2012, respectively. Peoples also had pledged commercial loans to secure borrowings with the FRB. The outstanding balances of these loans totaled $113.0 million and $123.8 million at December 31, 2013 and December 31, 2012, respectively.
	Related Party Loans
	In the normal course of its business, Peoples Bank has granted loans to certain directors and officers of Peoples, including their affiliates, families and entities in which they are principal owners. Related party loans were made on substantially the same terms, including interest rates charged and collateral required, as those prevailing at the time for comparable loans with unrelated persons and did not involve more than normal risk of collectibility. At December 31, 2013, no related party loan was past due 90 or more days, renegotiated or on nonaccrual status. Activity in related party loans is presented in the table below:
	(Dollars in thousands)
	Balance, December 31, 2012	$	7,011

	Repayments	(7,085		)
	Balance, December 31, 2013	$	11,359
	Nonaccrual and Past Due Loans
	The recorded investments in loans on nonaccrual status and accruing loans delinquent for 90 days or more were as follows:

During 2013, Peoples identified certain home equity lines of credit that had matured and were not sent notices that the principal was due. The majority of the borrowers continued to make required payments past maturity and had not defaulted. These loans should have been reported as past due since the principal was contractually due during a previous period. The total balance of these loans was $0.8 million at December 31, 2013, $1.2 million and $0.8 million at December 31, 2012 and 2011, respectively. Peoples has mailed letters to these customers, informing of the amount of principal due. Peoples has adjusted prior period amounts reported to appropriately reflect the payment status of these loans, and expects the impact of these loans on past due balances to decrease significantly during the first quarter of 2014.
Credit Quality Indicators
As discussed in Note 1, 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 debt 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 asset 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 by the collateral pledged, if any. Loans so classified have one or more well-defined weaknesses that jeopardize the orderly repayment of debt. 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:

	Peoples’ retail repurchase agreements consist of overnight agreements with Peoples’ commercial customers and serve as a cash management tool.
	The FHLB advances consist of overnight borrowings and other advances with an original maturity of one year or less.  These advances, along with the long-term advances disclosed in Note 10, are collateralized by residential mortgage loans and investment securities.  Peoples’ borrowing capacity with the FHLB is based on the amount of collateral pledged and the amount of FHLB common stock owned.
	Other short-term borrowings consist of Federal Funds purchased and advances from the Federal Reserve Discount Window.  Federal Funds purchased are short-term borrowings from correspondent banks that typically mature within one to ninety days.  Peoples has available Federal Funds of $20 million from certain of its correspondent banks.  Interest on Federal Funds purchased is set daily by the correspondent bank based on prevailing market rates.  The Federal Reserve Discount Window provides credit facilities to financial institutions, which are designed to ensure adequate liquidity by providing a source of short-term funds.  Discount Window advances are typically overnight and must be secured by collateral acceptable to the lending Federal Reserve Bank.
	On December 19, 2012, Peoples obtained a $5 million revolving credit loan from an unaffiliated financial institution that matured on December 17, 2013. The loan was renewed for an additional one year term on December 17, 2013. This loan bears interest at a fixed per annum rate equal to 3% plus the one-month LIBOR rate, to be reset monthly. This revolving credit loan is subject to the same covenants as detailed in Note 10 for the term loan. At December 31, 2013, this revolving credit loan had no outstanding principal balance.

	On December 18, 2012, Peoples entered into a Loan Agreement (the "Loan Agreement") to obtain a $24 million unsecured term loan from an unaffiliated financial institution with an original maturity of 5 years. 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 Loan Agreement, which include restrictions on ownership interests of its subsidiaries; issuance of dividends; 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 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 Bank must maintain a ratio of "Allowance for Loan Losses" to "Nonperforming Loans" (as each term is defined in the Loan Agreement) of not less than 80% measured as of the last day of each fiscal quarter; and
	•	Peoples must maintain a "Fixed Charge Coverage Ratio" (as defined in the 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 training 12-month basis.
	As of December 31, 2013, Peoples was in compliance with the applicable material covenants imposed by the Loan Agreement.
	Peoples' national market repurchase agreements consist of agreements with unrelated financial service companies and have original maturities ranging from 5 to 10 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 3 months to 5 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 10 to 20 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 3 months to 5 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 10 to 20 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. As discussed in Note 8, long-term FHLB advances are collateralized by assets owned by Peoples.
	At December 31, 2013, the aggregate minimum annual retirements of long-term borrowings in future periods were as follows:
	(Dollars in thousands)	Balance		Weighted-Average Rate

	Under its Amended Articles of Incorporation, Peoples is authorized to issue up to 50,000 preferred shares, in one or more series, having such voting powers, designations, preferences, rights, qualifications, limitations and restrictions as determined by the Board of Directors.  In 2009, Peoples’ Board of Directors created a series of preferred shares designated as Peoples’ Fixed Rate Cumulative Perpetual Preferred Shares, Series A, each without par value and having a liquidation preference of $1,000 per share, and fixed 39,000 shares as the authorized number of such shares (the “Series A Preferred Shares”).  These Series A Preferred Shares subsequently were sold to the United States Department of the Treasury (the “U.S. Treasury”), along with a ten-year warrant (the “Warrant”) to purchase 313,505 Peoples common shares at an exercise price of $18.66 per share (subject to certain anti-dilution and other adjustments), for an aggregate purchase price of $39 million in cash in connection with Peoples’ participation in the U.S. Treasury’s TARP Capital Purchase Program. The entire 39,000 Series A Preferred Shares were repurchased during 2011 at an aggregate price of $39 million.
	Peoples repurchased the Warrant for a purchase price of $1.2 million in 2012.

Defined Benefit Pension Plans and Defined Benefit Postretirement Plans 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. Effective July 1, 2013, a participant in the pension plan who is employed by Peoples may elect to receive or to commence receiving such person's retirement benefits as of the later of such person's normal retirement date or the first day of the month first following the date such person makes an election to receive his or her retirement benefits.
	Peoples also provides post-retirement health and life insurance benefits to former employees and directors. Only those individuals who retired before January 27, 2012 were eligible for life insurance benefits. All retirees are eligible for health benefits; however, Peoples only pays 100% of the cost for those individuals who retired before January 1, 1993. For all others, the retiree is responsible for most, if not all, of the cost of health benefits.  Peoples’ policy is to fund the cost of the benefits as they arise.
	The following tables provide a reconciliation of the changes in the plans’ benefit obligations and fair value of assets over the two-year period ended December 31, 2013, and a statement of the funded status as of December 31, 2013 and 2012:

	The estimated costs relating to Peoples’ pension benefits that will be amortized from accumulated other comprehensive income (loss) into net periodic cost over the next fiscal year are $131,000 of net loss.
	Net Periodic Benefit Cost
	The following tables detail the components of the net periodic benefit cost for the plans:
		Pension Benefits										Postretirement Benefits
	(Dollars in thousands)	2013			2012			2011				2013			2012			2011

	Net periodic benefit cost	$	343		$	840		$	581			$	(2	)	$	8		$	3
	Weighted-average assumptions:
	Discount rate	3.75		%	4		%	5.4		%		3.3		%	4		%	5.7		%
	Expected return on plan assets	7.5		%	7.5		%	8		%		n/a			n/a			n/a
	Rate of compensation increase	n/a			n/a			n/a				n/a			n/a			n/a
	For measurement purposes, an 8% annual rate of increase in the per capita cost of covered benefits (i.e., health care cost trend rate) was assumed for 2013, grading down to an ultimate rate of 5% in 2026. The health care trend rate assumption does not have a significant effect on the contributory defined benefit postretirement plan; therefore, a one percentage point increase or decrease in the trend rate is not material in the determination of the accumulated postretirement benefit obligation or the ongoing expense.
	Under US GAAP, Peoples is required to recognize a settlement gain or loss when the aggregate amount of lump-sum distributions to participants equals or exceeds the sum of the service and interest cost components of the net periodic pension cost. The amount of settlement gain or loss recognized is the pro rata amount of the unrealized gain or loss existing immediately prior to the settlement. In general, both the projected benefit obligation and fair value of plan assets are required to be remeasured in order to determine the settlement gain or loss.
	In the third quarter of 2013, the total lump-sum distributions made to participants, when added to the lump-sum distributions made through the first six months of 2013, caused the total settlements through nine months of 2013 to exceed the recognition threshold for settlement gains or losses. As a result, Peoples remeasured its pension obligation and plan assets as of July 1, 2013 as part of the calculation of the settlement loss recognized.
	Determination of Expected Long-term Rate of Return
	The expected long-term rate of return on the plans' total assets is based on the expected return of each category of the plan's assets. Peoples' investment strategy for the plan's assets continues to allocate 60% to 75% to equity securities. The returns generated by equity securities over the last 10 years have been significantly lower than their long-term historical annual returns due in part to unfavorable economic conditions. Thus, Peoples lowered its expected return on equity securities from their long-term historical rate, which had a corresponding impact on overall expected return on plan assets in 2011.
	Plan Assets
	Peoples' investment strategy, as established by Peoples' Retirement Plan Committee, is to invest assets based upon established target allocations, which include a target range of 60-75% allocation in equity securities, 24-39% in debt securities and approximately 1% of other investments. The assets are reallocated periodically to meet the target allocations. The investment policy is reviewed periodically, under the advisement of a certified investment advisor, to determine if the policy should be changed.
	The following table provides the fair values of investments held in Peoples' pension plan at December 31, by major asset category:
	(Dollars in thousands)	Fair Value				Quoted Prices in Active Markets for Identical Assets				Significant Other Observable Inputs

Pension plan assets also included cash and cash equivalents of $400,000 and accrued income of $20,000 at December 31, 2013. Cash and cash equivalents were $401,000 and accrued income was $22,000 at December 31, 2012. For further information regarding levels of input used to measure fair value, please refer to Note 2.
Equity securities of Peoples' pension plan did not include any securities of Peoples or related parties in 2013 or 2012.
Cash Flows
Peoples has not determined if any contributions will be made to its pension plan in 2014; however, actual contributions are made at the discretion of the Retirement Plan Committee and Peoples' Board of Directors. Estimated future benefit payments, which reflect benefits attributable to estimated future service, for the years ending December 31 are as follows:
(Dollars in thousands)	Pension Benefits				Postretirement Benefits
2014	$	3,280			$	21
2015	1,149				22
2016	1,158				22
2017	874				22
2018	925				12
2019 to 2023	4,120				50
Total	$	11,506			$	149
Retirement Savings Plan
Peoples also maintains a retirement savings plan, or 401(k) plan, which covers substantially all employees. The plan provides participants the opportunity to save for retirement on a tax-deferred basis. During 2009 and in prior years, Peoples made matching contributions equal to 100% of participants' contributions that did not exceed 3% of the participants' compensation, plus 50% of participants' contributions between 3% and 5% of the participants' compensation. Effective January 1, 2010, Peoples began making matching contributions equal to 100% of participants' contributions that do not exceed 2% of the participants' compensation. Beginning January 1, 2011, matching contributions equaled 100% of participants' contributions that did not exceed 3% of the participants' compensation, plus 50% of participants' contributions between 3% and 5% of the participants' compensation. Matching contributions made by Peoples totaled $924,000, $758,000 and $763,000 in 2013, 2012 and 2011, respectively.

Financial Instruments with Off-Balance Sheet Risk [Abstract]	'
Financial Instruments Disclosure [Text Block]	'
	Financial Instruments with Off-Balance Sheet Risk
	In the normal course of business, Peoples is party to financial instruments with off-balance sheet risk necessary to meet the financing needs of customers. These financial instruments include commitments to extend credit and standby letters of credit. The instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the Consolidated Balance Sheets. The contract amounts of these instruments express the extent of involvement Peoples has in these financial instruments.
	Loan Commitments and Standby Letters of Credit
	Loan commitments are made to accommodate the financial needs of Peoples' customers. Standby letters of credit are instruments issued by Peoples Bank guaranteeing the beneficiary payment by Peoples Bank in the event of default by Peoples Bank's customer in the nonperformance of an obligation or service. Historically, most loan commitments and standby letters of credit expire unused. Peoples' exposure to credit loss in the event of nonperformance by the counter-party to the financial instrument for loan commitments and standby letters of credit is represented by the contractual amount of those instruments. Peoples uses the same underwriting standards in making commitments and conditional obligations as it does for on-balance sheet instruments. The amount of collateral obtained is based on management's credit evaluation of the customer. Collateral held varies, but may include accounts receivable, inventory, property, plant, and equipment, and income-producing commercial properties.
	The total amounts of loan commitments and standby letters of credit at December 31 are summarized as follows:
	(Dollars in thousands)	2013		2012
	Home equity lines of credit	$	49,533	$	43,818
	Unadvanced construction loans	30,203		11,839
	Other loan commitments	137,661		113,868
	Loan commitments	217,397		169,525
	Standby letters of credit	$	33,998	$	35,373
	Interest Rate Swaps
	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 $14.7 million and fair value of $0.7 million at December 31, 2013, and a notional value of $11.2 million and fair value of $1.4 million at December 31, 2012. These interest rate swaps did not have a material impact on Peoples' results of operation or financial condition.

Regulatory Matters [Abstract]	'
Regulatory Capital Requirements under Banking Regulations	'
	Regulatory Matters
	The following is a summary of certain regulatory matters affecting Peoples and its subsidiaries:
	Federal Reserve Requirements
	Peoples Bank is required to maintain a minimum level of reserves, consisting of cash on hand and non-interest-bearing balances with the FRB, based on the amount of deposit liabilities. Average required reserve balances were approximately $11.2 million and $5.8 million in 2013 and 2012, respectively.
	Limits on Dividends
	The primary source of funds for the dividends paid by Peoples is dividends received from Peoples Bank. The payment of dividends by Peoples Bank is subject to various banking regulations. The most restrictive provision requires regulatory approval if dividends declared in any calendar year exceed the total net profits of that year plus the retained net profits of the preceding two years. At December 31, 2013, Peoples Bank had approximately $5.9 million of net profits available for distribution to Peoples as dividends without regulatory approval.
	Capital Requirements
	Peoples and Peoples Bank are subject to various regulatory capital guidelines administered by the banking regulatory agencies. Under capital adequacy requirements and the regulatory framework for prompt corrective action, Peoples and its banking subsidiary must meet specific capital guidelines that involve quantitative measures of each entity's assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. Peoples' and Peoples Bank's capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Failure to meet future minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by the regulators that, if undertaken, could have a material effect on Peoples' financial results.
	Quantitative measures established by regulation to ensure capital adequacy require Peoples and Peoples Bank to maintain minimum amounts and ratios of Total and Tier I capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier I capital (as defined) to average assets (as defined). Peoples and Peoples Bank met all capital adequacy requirements at December 31, 2013.
	As of December 31, 2013, the most recent notifications from the banking regulatory agencies categorized Peoples and Peoples Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, Peoples and Peoples Bank must maintain minimum Total risk-based, Tier I risk-based and Tier I leverage ratios as set forth in the table below. There are no conditions or events since these notifications that management believes have changed Peoples or Peoples Bank's category.
	Peoples and Peoples Bank's actual capital amounts and ratios as of December 31 are also presented in the following table:

Share-based Compensation [Abstract]	'
Stock-Based Compensation	'
	Stock-Based Compensation
	Under the Peoples Bancorp Inc. 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 common 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 shares that can be issued for incentive stock options is 800,000 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 summarizes the changes to Peoples' stock options for the year ended December 31, 2013:
			Number of Common Shares Subject to Options				Weighted-Average Exercise Price				Weighted-Average Remaining Contractual Life		Aggregate Intrinsic Value
	Outstanding at January 1		101,594				$	26.09
	Expired		44,500				23.69
	Outstanding at December 31		57,094				$	27.96			1.4 years		$	—
	Exercisable at December 31		57,094		—		$	27.96			1.4 years		$	—
	The following table summarizes Peoples’ stock options outstanding at December 31, 2013:
				Options Outstanding & Exercisable
	Range of Exercise Prices			Common Shares Subject to Options Outstanding		Weighted-Average Remaining Contractual Life	Weighted-Average
							Exercise Price
	$23.59	to	$25.94	2,792		0.6 years	$	25.41
	$26.01	to	$27.74	20,334		1.0 year	27.08
	$28.25	to	$28.26	17,632		1.8 years	28.25
	$28.57	to	$30.00	16,336		1.7 years	29.17
	Total			57,094		1.4 years	$	27.96
	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 vested three years after the grant date and expire ten years from the date of grant. The most recent grant of SARs occurred in 2008. The following summarizes the changes to Peoples' SARs for the year ended December 31, 2013:
			Number of Common Shares Subject to SARs			Weighted-				Weighted-		Aggregate Intrinsic
						Average				Average		Value
						Exercise				Remaining Contractual
						Price				Life
	Outstanding at January 1		22,849			$	25.97
	Forfeited		1,557			25.99
	Outstanding at December 31		21,292			$	25.96			3.7 years		$	—
	Exercisable at December 31		21,292			$	25.96			3.7 years		$	—
	The following table summarizes Peoples’ SARs outstanding at December 31, 2013:
	Exercise Price	Number of Common Shares Subject to SARs Outstanding & Exercisable		Weighted-
				Average Remaining Contractual
				Life
	$23.26	2,000		3.6 years
	$23.77	10,582		4.1 years
	$29.25	8,710		3.1 years
	Total	21,292		3.7 years
	Restricted 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 common shares awarded to non-employee directors expire after six months, while the restrictions on common shares awarded to employees expire after periods ranging from one to three years. In the first quarter of 2013, Peoples granted restricted common shares to non-employee directors with a six months time-based vesting period. Also during the first quarter of 2013, Peoples granted restricted common shares subject to performance-based vesting to officers and key employees with restrictions that will lapse one to three years after the grant date provided that in order for the restricted common shares to vest on each of the three foregoing dates, Peoples must have reported positive net income and maintained a well capitalized status by regulatory standards in the year immediately preceding the vesting date. In addition, Peoples has granted restricted common shares during 2013 to attract and/or retain key employees with vesting periods ranging from one to three years.
	The following summarizes the changes to Peoples’ restricted common shares for the period ended December 31, 2013:
		Time Vesting						Performance Vesting
		Number of Shares		Weighted-Average Grant Date Fair Value				Number of Shares		Weighted-Average Grant Date Fair Value
	Outstanding at January 1	78,731		$	16.36			17,865		$	16.07
	Awarded	10,500		21.75				72,706		21.82
	Released	27,262		16.62				3,154		13.14
	Forfeited	1,763		16.22				2,163		19.97
	Outstanding at December 31	60,206		$	17.18			85,254		$	20.98
	The total intrinsic value of restricted common shares released was $654,000, $77,000 and $307,000 in 2013, 2012 and 2011, respectively.
	Stock-Based Compensation
	Peoples recognized 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 summarizes the amount of stock-based compensation expense and related tax benefit recognized:
	(Dollars in thousands)	2013			2012			2011
	Total stock-based compensation	$	1,362		$	942		$	310
	Recognized tax benefit	(477		)	(330		)	(109		)
	Net expense recognized	$	885		$	612		$	201
	Restricted common shares were the only stock-based compensation awards granted by Peoples in 2013, 2012 and 2011. The fair value of restricted stock awards on the grant date is the market price of Peoples' common shares. Total unrecognized stock-based compensation expense related to unvested awards was $824,000 at December 31, 2013, which will be recognized over a weighted-average period of 1.5 years. In 2012, the Board of Directors granted 8,490 unrestricted common shares to certain employees that did not already participate in the 2006 Equity Plan, which resulted in an additional $180,000 of stock-based compensation expense being recognized.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2013
Accounting Policies [Abstract]	'
Basis of Presentation	'
	The accounting and reporting policies of Peoples Bancorp Inc. and 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.) conform to generally accepted accounting principles in the United States of America (“US GAAP”) and to general practices within the banking industry. The preparation of the financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Certain items in prior financial statements have been reclassified to conform to the current presentation, which had no impact on net income, comprehensive income or loss, net cash provided by operating activities or stockholders' equity.
Consolidation	'
	Consolidation: Peoples' Consolidated Financial Statements include subsidiaries in which Peoples has a controlling financial interest, principally defined as owning a voting interest greater than 50%. In addition, entities not controlled by voting interest or in which the equity investors do not bear the residual economic risks, but for which Peoples is the primary beneficiary are also consolidated.
	The Consolidated Financial Statements include the accounts of Peoples and its consolidated subsidiaries, Peoples Bank and Peoples Investment Company, along with their wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents: Cash and cash equivalents include cash on hand, balances due from other banks, interest-bearing deposits in other banks, Federal Funds sold and other short-term investments with original maturities of ninety days or less. Included in interest-bearing deposits in other banks were $3.0 million in funds at both December 31, 2013 and 2012, which were being used as collateral and not available for withdrawal.
Investment Securities	'
	Investment Securities: Investment securities are recorded initially at cost, which includes premiums and discounts if purchased at other than par or face value. Peoples amortizes premiums and accretes discounts as an adjustment to interest income on a level yield basis. The cost of investment securities sold, and any resulting gain or loss, is based on the specific identification method and recognized as of the trade date.
	Management determines the appropriate classification of investment securities at the time of purchase. Held-to-maturity securities are those securities that Peoples has the positive intent and ability to hold to maturity and are recorded at amortized cost. Available-for-sale securities are those securities that would be available to be sold in the future in response to Peoples' liquidity needs, changes in market interest rates, and asset-liability management strategies, among other considerations. Available-for-sale securities are reported at fair value, with unrealized holding gains and losses reported in stockholders' equity as a separate component of other comprehensive income or loss, net of applicable deferred income taxes.
	Certain restricted equity securities that do not have readily determinable fair values and for which Peoples does not exercise significant influence, are carried at cost. These cost method securities are reported as other investment securities on the Consolidated Balance Sheets and consist solely of shares of the Federal Home Loan Bank of Cincinnati (the “FHLB”), the Federal Reserve Bank of Cleveland (the "FRB") and a capital investment in West Virginia Bankers Insurance.
	Management systematically evaluates investment securities for other-than-temporary declines in fair value on a quarterly basis. This analysis requires management to consider various factors, which include (1) the duration and magnitude of the decline in value, (2) the financial condition of the issuer or issuers and (3) the structure of the security.
	An impairment loss is recognized in earnings only when (1) Peoples intends to sell the debt security; (2) it is more likely than not that Peoples will be required to sell the security before recovery of its amortized cost basis or (3) Peoples does not expect to recover the entire amortized cost basis of the security. In situations where Peoples intends to sell or when it is more likely than not that Peoples will be required to sell the security, the entire impairment loss must be recognized in earnings. In all other situations, only the portion of the impairment loss representing the credit loss must be recognized in earnings, with the remaining portion being recognized in stockholders' equity as a component of accumulated comprehensive income, net of deferred taxes.
Fair Value Measurements	'
	Fair Value Measurements: The measurement of fair value under US GAAP uses a hierarchy intended to maximize the use of observable inputs and minimize the use of unobservable inputs.  This hierarchy uses three levels of inputs to measure the fair value of assets and liabilities as follows:
	Level 1: Quoted prices in active exchange markets for identical assets or liabilities; also includes certain U.S. Treasury and other U.S. government and agency securities actively traded in over-the-counter markets.
	Level 2: Observable inputs other than Level 1 including quoted prices for similar assets or liabilities, quoted prices in less active markets, or other observable inputs that can be corroborated by observable market data; also includes derivative contracts whose value is determined using a pricing model with observable market inputs or can be derived principally from or corroborated by observable market data.  This category generally includes certain U.S. government and agency securities, corporate debt securities, derivative instruments, and residential mortgage loans held for sale.
	Level 3: Unobservable inputs supported by little or no market activity for financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation; also includes observable inputs for single dealer nonbinding quotes not corroborated by observable market data. This category generally includes certain private equity investments, retained interests from securitizations, and certain collateralized debt obligations.
Securities Sold Under Agreements to Repurchase	'
	Securities Sold Under Agreements to Repurchase: Peoples enters into sales of securities under agreements to repurchase (“Repurchase Agreements”) with customers and other financial service companies, which are considered financings. As such, these obligations are recorded as a liability on the Consolidated Balance Sheets and disclosed in Notes 9 and 10. Securities pledged as collateral under Repurchase Agreements are included in investment securities on the Consolidated Balance Sheets and are disclosed in Note 3. The fair value of the collateral pledged to a third party is continually monitored and additional collateral is pledged or returned, as deemed appropriate.
Loans and Loans Held-For-Sale	'
	Loans: Loans originated that Peoples has the positive intent and ability to hold for the foreseeable future or to maturity or payoff are reported at the principal balance outstanding, net of deferred loan fees and costs and an allowance for loan losses. The foreseeable future is based upon current market conditions and business strategies, as well as balance sheet management and liquidity. As the conditions change, so may management's view of the foreseeable future. Net deferred loan costs were $2.3 million and $1.5 million at December 31, 2013 and 2012, respectively.
	A loan is considered impaired when information and events indicate it is probable that collection of all contractual principal and interest payments is doubtful. Impairment is evaluated in total for smaller-balance loans of a similar nature, primarily consumer and residential real estate loans, and on an individual loan basis for all loans to borrowers with an aggregate unpaid principal balances in excess of $1 million. Peoples typically places any loan deemed to be impaired on nonaccrual status and allocates a specific portion of the allowance for loan losses, if necessary, to reduce the net carrying value of the loan to its estimated net realizable value. Impaired loans, or portions thereof, are charged off when deemed uncollectible. Upon detection of the reduced ability of a borrower to meet cash flow obligations, consumer and residential real estate loans typically are charged down to the net realizable value, with the residual balance placed on nonaccrual status.
	Loans acquired in a business combination that have evidence of deterioration of credit quality since origination and for which it is probable, at acquisition, that Peoples will be unable to collect all contractually required payments receivable are initially recorded at fair value (the present value of the amounts expected to be collected) with no valuation allowance. The difference between the undiscounted cash flows expected at acquisition and the investment in the loan is recognized as interest income on a level-yield method over the life of the loan. Contractually required payments for interest and principal that exceed the undiscounted cash flows expected at acquisition are not recognized.
	Over the life of these acquired loans, management continues to monitor each acquired loan portfolio for changes in credit quality. Increases in expected cash flows subsequent to acquisition are recognized prospectively over their remaining life as a yield adjustment on the loans. Subsequent decreases in expected cash flows are recognized as impairment, with the amount of the expected loss included in management's evaluation of the adequacy of the allowance for loan losses.
	Loans Held-for-Sale: Loans originated and intended to be sold in the secondary market, generally one-to-four family residential loans, are carried at the lower of cost or estimated fair value determined on an aggregate basis. Gains and losses on sales of loans held for sale are included in mortgage banking income.
	Loans originated with the intent to be held in our portfolio are subsequently transferred to held-for-sale when a decision is made to sell these loans. At the time of a loan's transfer to the held-for-sale classification, the loan is recorded at the lower of cost or its fair value. Any reduction in the loan's value is reflected as a write-down of the recorded investment resulting in a new cost basis, with a corresponding charge against the allowance for loan losses. If the fair value of a loan classified as held-for-sale in subsequent periods is less than its cost basis, the carrying value of the loan is adjusted accordingly, with the corresponding loss recognized in earnings.
	Peoples enters into interest rate lock commitments with borrowers and best efforts commitments with investors on loans originated for sale into the secondary markets to manage the inherent interest rate and pricing risk associated with selling loans. The interest rate lock commitments generally terminate once the loan is funded, the lock period expires or the borrower decides not to contract for the loan. The best efforts commitments generally terminate once the loan is sold, the commitment period expires or the borrower decides not to contract for the loan. These commitments are considered derivatives which are generally accounted for by recognizing their estimated fair value on the Consolidated Balance Sheets as either a freestanding asset or liability. The valuation of such commitments does not consider expected cash flows related to the servicing of the future loan. Management has determined these derivatives do not have a material effect on Peoples' financial position, results of operations or cash flows.
Allowance for Loan Losses	'
	Allowance for Loan Losses: The allowance for loan losses is a valuation reserve established through provisions for loan losses charged against income. The allowance for loan losses is maintained at a level that management deems sufficient to absorb probable losses inherent in the loan portfolio. Loans deemed to be uncollectible are charged against the allowance for loan losses, while recoveries of previously charged-off amounts are credited to the allowance for loan losses.
	The allowance for loan losses is comprised of specific valuation allowances for loans evaluated individually for impairment and general allocations for pools of homogeneous loans with similar risk characteristics and trends. Peoples' homogenous loan pools include similarly risk-graded commercial and industrial loans, similarly risk-graded commercial real estate loans, real estate construction loans (both commercial and residential), residential real estate loans, consumer home equity loans and other consumer loans. Management's evaluation of the adequacy of the allowance for loan losses and the appropriate provision for loan losses is based upon a quarterly analysis of the portfolio. While portions of the allowance for loan losses may be allocated to specific loans; the entire allowance for loan losses is available for any loan charged off by management.
	The allowance for loan losses related to specific loans is based on management's estimate of potential losses on impaired loans as determined by (1) the present value of expected future cash flows; (2) the fair value of collateral if the loan is determined to be collateral dependent or (3) the loan's observable market price. The general allocations to specific loan pools are based on the historical loss rates for specific loan types and the internal risk grade, if applicable, adjusted for both internal and external qualitative risk factors. The calculation of historical loss ratios for pools of similar loans with similar characteristics is based upon the proportion of actual charge-offs experienced to the total population of loans in the pool. The historical loss ratios are periodically updated based on actual charge-off experience. The qualitative factors considered by management include, among other factors, (1) changes in local and national economic conditions; (2) changes in asset quality; (3) changes in loan portfolio volume; (4) the composition and concentrations of credit; (5) the impact of competition on loan structuring and pricing; (6) the impact of interest rate changes on portfolio risk and (7) effectiveness of Peoples' loan policies, procedures and internal controls. The total allowance established for each homogenous loan pool represents the product of the historical loss ratio and the total dollar amount of the loans in the pool.
	Peoples categorizes loans involving commercial borrowers into risk categories based upon an established grading matrix. This system is used to manage the risk within its commercial lending activities, evaluate changes in the overall credit quality of the loan portfolio and evaluate the adequacy of the allowance for loan losses. Loan grades are assigned at the time a new loan or lending commitment is extended by Peoples and may be changed at any time when circumstances warrant. Peoples reviews, at least annually, all loan relationships with aggregate outstanding debt to Peoples of $1,000,000 or more, with adversely classified loans generally reviewed on a quarterly basis.
	The primary factors considered when assigning a risk grade to a loan include (1) reliability and sustainability of the primary source of repayment; (2) past, present and projected financial condition of the borrower and (3) current economic and industry conditions. Other factors that could influence the risk grade assigned include the type and quality of collateral and strength of guarantors. The primary source of repayment for commercial real estate loans and commercial and industrial loans is normally the business's operating cash flow available to repay debt. Management's analysis of operating cash flow for commercial real estate loans secured by non-owner occupied properties takes into account factors such as rent rolls and vacancy statistics. Management's analysis of operating cash flow for commercial real estate loans secured by owner occupied properties and all commercial and industrial loans considers the profitability, liquidity and leverage of the business. The evaluation of construction loans is based largely on the borrower's ability to complete construction within the established budget.
	The primary factors considered when classifying consumer loans include the loan's past due status and declaration of bankruptcy by the borrower(s). The classification of residential real estate and home equity lines of credit also takes into account the current value of the underlying collateral.
Troubled Debt Restructuring	'
	Troubled Debt Restructuring: The restructuring of a loan is considered a troubled debt restructuring ("TDR") if both (i) the borrower is experiencing financial difficulties and (ii) the creditor has granted a concession.
	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 debtor is currently in payment default on any of its debt; (ii) a payment default is probable in the foreseeable future without the modification; (iii) the debtor has declared or is in the process of declaring bankruptcy and (iv) the debtor'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 debtor'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.
Bank Premises and Equipment	'
	Bank Premises and Equipment: Bank premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed on the straight-line method over the estimated useful lives of the related assets owned. Major improvements to leased facilities are capitalized and included in bank premises at cost less accumulated depreciation, which is calculated on the straight-line method over the lesser of the remaining term of the leased facility or the estimated economic life of the improvement.
Bank Owned Life Insurance	'
	Bank Owned Life Insurance: Bank owned life insurance (“BOLI”) represents life insurance on the lives of certain employees who have provided positive consent allowing Peoples Bank to be the beneficiary of such policies. These policies are recorded at their cash surrender value, or the amount that can be realized upon surrender of the policies. Income from these policies and changes in the cash surrender value are recorded in other income.
Investments in Affordable Housing Limited Partnerships	'
	Investments in Affordable Housing Limited Partnerships: Investments in affordable housing consist of investments in limited partnerships that operate qualified affordable housing projects or that invest in other limited partnerships formed to operate affordable housing projects. These investments are considered variable interest entities for which Peoples is not the primary beneficiary. Peoples generally utilizes the effective yield method to account for these investments with the tax credits, net of the amortization of the investment, reflected in the Consolidated Statements of Income as a reduction of income tax expense. The unamortized amount of the investments is recorded in other assets and totaled $0.3 million and $0.8 million at December 31, 2013 and 2012, respectively.
Other Real Estate Owned	'
	Other Real Estate Owned: Other real estate owned (“OREO”), included in other assets on the Consolidated Balance Sheets, is comprised primarily of commercial and residential real estate properties acquired by Peoples Bank in satisfaction of a loan. OREO obtained in satisfaction of a loan is recorded at the lower of cost or estimated fair value, less estimated costs to sell the property. Peoples had OREO totaling $0.9 million at December 31, 2013, and $0.8 million at December 31, 2012.
Goodwill and Other Intangible Assets	'
	Goodwill and Other Intangible Assets: Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired in the business combination. Goodwill is not amortized but is tested for impairment at least annually and updated quarterly if necessary. Based upon the most recently completed goodwill impairment test, Peoples concluded the recorded value of goodwill was not impaired as of December 31, 2013, based upon the estimated fair value of Peoples' single reporting unit.
	Peoples' other intangible assets consist of customer relationship intangible assets representing the present value of future net income to be earned from acquired customer relationships with definite useful lives. These intangible assets are amortized on an accelerated basis over their estimated lives ranging from 7 to 10 years.
Mortgage Servicing Rights	'
	Servicing Rights: Servicing rights (“SRs”) represent the right to service loans sold to third-party investors. SRs are recognized separately as a servicing asset or liability whenever Peoples undertakes an obligation to service financial assets. SRs are reported in other intangible assets on the Consolidated Balance Sheets. Serviced loans are not included in the Consolidated Balance Sheets. Loan servicing income included in mortgage banking income includes servicing fees received from the third-party investors and certain charges collected from the borrowers.
	Peoples initially records SRs at fair value at the time of the sale of the loans to the third-party investor. Peoples follows the amortization method for the subsequent measurement of each class of separately recognized servicing assets and liabilities. Under the amortization method, Peoples amortizes the value of servicing assets or liabilities in proportion to and over the period of estimated net servicing income or net servicing loss and assesses servicing assets or liabilities for impairment or increased obligation based on fair value at each reporting date. The fair value of the SRs is determined by using a discounted cash flow model, which estimates the present value of the future net cash flows of the servicing portfolio based on various factors, such as servicing costs, expected prepayment speeds and discount rates.
Preferred Stock and Common Stock Warrant	'
	Preferred Stock and Common Stock Warrant: As more fully described in Note 11, Peoples issued preferred stock and a common stock warrant, subsequently redeemed in 2011 and 2012, respectively, that were classified in stockholders' equity on the Consolidated Balance Sheets. The preferred stock had similar characteristics of an “Increasing Rate Security” as described by Securities and Exchange Commission (“SEC”) Staff Accounting Bulletin Topic 5Q, Increasing Rate Preferred Stock. The proceeds received in conjunction with the issuance of the preferred stock and common stock warrant were allocated to the preferred stock and common stock warrant based on their relative fair values. Discounts on the increasing rate preferred stock were amortized over the expected life of the preferred stock (5 years), by charging imputed dividend cost against retained earnings and increasing the carrying amount of the preferred stock by a corresponding amount. The discount at the time of issuance was computed as the present value of the difference between dividends that would be payable in future periods and the dividend amount for a corresponding number of periods, discounted at a market rate for dividend yield on comparable securities. The amortization in each period was the amount which, together with the stated dividend in the period, resulted in a constant rate of effective cost with regard to the carrying amount of the preferred stock.
	Common stock warrants are evaluated for liability or equity treatment. The common stock warrant issued by Peoples was carried in stockholders' equity until repurchased based on the view of both the SEC and Financial Accounting Standards Board (the “FASB”) that they would not object to classification of such form of common stock warrant as permanent equity. This view is consistent with the objective of the Capital Purchase Program that the equity represented by these securities should be considered part of equity for regulatory reporting purposes. The fair value of the common stock warrant used in allocating total proceeds received was determined based on a binomial model.
Trust Assets Under Management	'
	Trust Assets Under Management: Peoples Bank manages certain assets held in a fiduciary or agency capacity for customers. These assets under management, other than cash on deposit at Peoples Bank, are not included in the Consolidated Balance Sheets since they are not assets of Peoples Bank.
Interest Income Recognition	'
	Interest Income Recognition: Interest income on loans and investment securities is recognized by methods that result in level rates of return on principal amounts outstanding. Amortization of premiums has been deducted from, and accretion of discounts has been added to, the related interest income. Nonrefundable loan fees and direct loan costs are deferred and recognized over the life of the loan as an adjustment of the yield.
	Peoples discontinues the accrual of interest on all loans, whether or not such loans are considered past due, when management believes it is probable the borrower will be unable to meet its payment obligations as they become due, as well as when required by regulatory provisions. When interest accrual is discontinued, all unpaid accrued interest is reversed. Interest received on nonaccrual loans is included in income only if principal recovery is reasonably assured. A nonaccrual loan is restored to accrual status when it is brought current, has performed in accordance with contractual terms for a reasonable period of time, and the collectibility of the total contractual principal and interest is no longer in doubt.
Other Income Recognition	'
	Other Income Recognition: Service charges on deposits include cost recovery fees associated with services provided, such as overdraft and non-sufficient funds. Trust and investment income consists of revenue from fiduciary activities, which include fees for services such as asset management, recordkeeping, retirement services and estate management, and investment commissions and fees related to the sale of investments. Income from these activities is recognized at the time the related services are performed.
	Insurance income consists of commissions and fees from the sales of insurance policies and related insurance services. Insurance commission income is recognized as of the effective date of the insurance policy, net of adjustments, including policy cancellations. Such adjustments are recorded when the amount can be reasonably estimated, which is generally in the period in which they occur. Contingent performance-based commissions from insurance companies are recognized when received and no contingencies remain.
Income Taxes	'
	Income Taxes: Peoples and its subsidiaries file a consolidated federal income tax return. Deferred income tax assets and liabilities are provided for temporary differences between the tax basis of an asset or liability and its reported amount in the Consolidated Financial Statements at the statutory Federal tax rate. A valuation allowance, if needed, reduces deferred tax assets to the expected amount most likely to be realized. Realization of deferred tax assets is dependent upon the generation of a sufficient level of future taxable income and recoverable taxes paid in prior years. The components of other comprehensive income or loss included in the Consolidated Statements of Stockholders' Equity have been computed based upon a 35% Federal tax rate.
	A tax position is initially recognized in the financial statements when it is more likely than not the position will be sustained upon examination by the tax authorities. Such tax positions are initially and subsequently measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement with the tax authority assuming full knowledge of the position and all relevant facts. Penalties and interest incurred under the applicable tax law are classified as income tax expense. The amount of Peoples' uncertain income tax positions, unrecognized benefits and accrued interest were immaterial at both December 31, 2013 and 2012.
Advertising Costs	'
	Advertising Costs: Advertising costs are generally expensed as incurred.
Earnings Per Share	'
	Earnings per Share: Basic and diluted earnings per common share (“EPS”) are calculated using the two-class method since Peoples has issued share-based payment awards considered participating securities because they entitle holders to non-forfeitable rights to dividends during the vesting term. The two-class method is an earnings allocation formula that determines net income per share for each class of common stock and participating security according to dividends declared and participation rights in undistributed earnings. Basic earnings per common share is computed by dividing net earnings allocated to common shareholders by the weighted-average number of common shares outstanding.  Diluted earnings per common share is computed by dividing net earnings allocated to common shareholders by the weighted-average number of common shares outstanding adjusted to include the effect of potentially dilutive common shares.  Potentially dilutive common shares include incremental common shares issuable upon exercise of outstanding stock options, SARs and non-vested restricted common shares using the treasury stock method.
Operating Segments	'
	Operating Segments: Peoples' business activities are currently confined to one reporting unit and reportable segment, which is community banking. As a community banking entity, Peoples offers its customers a full range of products including a complete line of banking, investment, insurance and trust solutions.
Stock-Based Compensation	'
	Stock-Based Compensation: Compensation costs for stock options, restricted stock awards and stock appreciation rights are measured at the fair value of these awards on their grant date. Compensation expense is recognized over the required service period, generally the vesting period for stock options and stock appreciation rights and the restriction period for restricted stock awards. For all awards, only the expense for the portion of the awards expected to vest is recognized. For service-based awards, compensation expense for awards granted to employees who are eligible for retirement is recognized to the date the employee is first eligible to retire.
New Accounting Pronouncements	'
	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.
	In February 2013, the Financial Accounting Standards Board issued an accounting standards update with new guidance on the presentation of accumulated other comprehensive income (“AOCI”). This standard was effective for public companies for interim and annual periods beginning after December 15, 2012. The amendment requires an entity to present the reclassification adjustments out of AOCI and into net income for each component reported. These amounts may be disclosed before-tax or after-tax, and must be disclosed in either the income statement or the notes to the financial statements. This update is intended to supplement changes made in 2012 to increase the prominence of items reported in other comprehensive income. Peoples adopted this new guidance on January 1, 2013, as required. As a result of the adoption, the disclosure of AOCI included in Note 11 contains additional information regarding reclassifications out of AOCI and into net income.
	In January 2014, the Financial Accounting Standards Board issued an accounting standards update allowing entities to make an accounting policy election with respect to using the proportional amortization method for investments in qualified affordable housing projects, if certain conditions are met. This standard will be effective for public companies for interim and annual periods beginning after December 15, 2014. Peoples will adopt this new guidance as required, and it is not expected to have a material impact on Peoples’ Consolidated Financial Statements.
	Also in January 2014, the Financial Accounting Standards Board issued an accounting standards update clarifying guidance for in substance reposessions and foreclosures, and requiring additional disclosures regarding foreclosed residential real estate property and recorded investments in consumer mortgage loans collateralized by residential real estate in the process of foreclosure. This standard will be effective for public companies for interim and annual periods beginning after December 15, 2014. Peoples will adopt this new guidance as required, and it is not expected to have a material impact on Peoples’ Consolidated Financial Statements.
