	Summary of Significant Accounting Policies
	Basis of Presentation: The accompanying Unaudited Consolidated Financial Statements of Peoples Bancorp Inc. ("Peoples") and its subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States (“US GAAP”) for interim financial information and the instructions for Form 10-Q and Article 10 of Regulation S-X.  Accordingly, these financial statements do not contain all of the information and footnotes required by US GAAP for annual financial statements and should be read in conjunction with Peoples’ Annual Report on Form 10-K for the fiscal year ended December 31, 2013 (“2013 Form 10-K”).
	The accounting and reporting policies followed in the presentation of the accompanying Unaudited Consolidated Financial Statements are consistent with those described in Note 1 of the Notes to the Consolidated Financial Statements included in Peoples’ 2013 Form 10-K, as updated by the information contained in this Form 10-Q.  Management has evaluated all significant events and transactions that occurred after March 31, 2014, for potential recognition or disclosure in these consolidated financial statements.  In the opinion of management, these consolidated financial statements reflect all adjustments necessary to present fairly such information for the periods and dates indicated.  Such adjustments are normal and recurring in nature.  All significant intercompany accounts and transactions have been eliminated.  The Consolidated Balance Sheet at December 31, 2013, contained herein has been derived from the audited Consolidated Balance Sheet included in Peoples’ 2013 Form 10-K.
	The preparation of the consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes.  Results of operations for interim periods are not necessarily indicative of the results to be expected for the full year, due in part to seasonal variations and unusual or infrequently occurring items.  Peoples’ insurance income includes contingent performance-based insurance commissions that are recognized by Peoples when received, which typically occurs during the first quarter of each year. For the three months ended March 31, 2014 and 2013, the amount of contingent performance-based insurance commissions recognized totaled $1.2 million and $504,000, respectively.
	New Accounting Pronouncements: 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 repossessions 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). Management reviews the valuation methodology and quality controls utilized by the pricing services in their overall assessment of the reasonableness of the fair values provided and challenges prices when it believes a material discrepancy in pricing exists.
	Certain financial assets and financial liabilities are measured at fair value on a non-recurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment).  Financial assets measured at fair value on a non-recurring basis included the following:
	Impaired Loans: Impaired loans are measured and reported at fair value when the amounts to be received are less than the carrying value of the loans. One of the allowable methods for determining the amount of impairment is estimating fair value using the fair value of the collateral for collateral-dependent loans. Management’s determination of the fair value for these loans uses a market approach representing the estimated net proceeds to be received from the sale of the collateral based on observable market prices or market value provided by independent, licensed or certified appraisers (Level 2 inputs).  At March 31, 2014, impaired loans were measured and reported with an outstanding principal balance and fair value of $1.3 million.  For the three months ended March 31, 2014, Peoples recognized losses of $28,000 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:
		March 31, 2014					December 31, 2013
	(Dollars in thousands)	Carrying Amount		Fair Value			Carrying Amount			Fair Value
	Financial assets:
	Cash and cash equivalents	$	64,684	$	64,684		$	53,820		$	53,820
	Investment securities	662,199		660,995			680,526			677,398
	Loans	1,212,583		1,193,525			1,180,857			1,165,560
	Financial liabilities:
	Deposits	$	1,633,065	$	1,639,212		$	1,580,758		$	1,587,448
	Short-term borrowings	68,777		68,777			113,590			113,590
	Long-term borrowings	120,164		126,662			121,826			128,205
	The methodologies for estimating the fair value of financial assets and liabilities that are measured at fair value on a recurring or non-recurring basis are discussed above.  For certain financial assets and liabilities, carrying value approximates fair value due to the nature of the financial instrument.  These instruments include cash and cash equivalents, demand and other non-maturity deposits and overnight borrowings.  Peoples used the following methods and assumptions in estimating the fair value of the following financial instruments:
	Loans: The fair value of portfolio loans assumes sale of the notes to a third-party financial investor.  Accordingly, this value is not necessarily the value to Peoples if the notes were held to maturity.  Peoples considered interest rate, credit and market factors in estimating the fair value of loans (Level 3 inputs).  In the current whole loan market, financial investors are generally requiring a much higher rate of return than the return inherent in loans if held to maturity given the lack of market liquidity.  This divergence accounts for the majority of the difference in carrying amount over fair value.
Deposits: The fair value of fixed maturity certificates of deposit is estimated using a discounted cash flow calculation based on current rates offered for deposits of similar remaining maturities (Level 2 inputs).
Long-term Borrowings: The fair value of long-term borrowings is estimated using 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.

	Peoples’ investment in equity securities was comprised largely of common stocks issued by various unrelated bank holding companies at both March 31, 2014 and December 31, 2013.  During the third quarter of 2013, Peoples also classified certain mutual funds as equity securities, which are intended for the payment of benefits under a deferred compensation plan for certain key officers of Peoples. At March 31, 2014, there were no securities of a single issuer, other than U.S. Treasury and government agencies and U.S. government sponsored agencies, that exceeded 10% of stockholders' equity.
	The gross gains and gross losses realized by Peoples from sales of available-for-sale securities for the periods ended March 31 were as follows:

	Management systematically evaluates available-for-sale investment securities for other-than-temporary declines in fair value on a quarterly basis. At March 31, 2014, management concluded no individual securities were other-than-temporarily impaired since Peoples did not have the intent to sell nor was it more likely than not that Peoples would be required to sell any of the securities with an unrealized loss prior to recovery. Further, the unrealized losses at both March 31, 2014 and December 31, 2013, were largely attributable to changes in market interest rates and spreads since the securities were purchased.
	At March 31, 2014, approximately 98% 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 2%, or four positions, consisted of privately issued mortgage-backed securities with all of the underlying mortgages originated prior to 2004. Two of the four positions had a fair value less than 90% of their book value, with an aggregate book and fair value of $0.9 million and $0.6 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 March 31, 2014 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 March 31, 2014.  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 northeastern, central and southeastern Ohio, west central West Virginia, and northeastern Kentucky. The major classifications of loan balances, excluding loans held for sale, were as follows:

	Total loans	$	1,226,506		$	1,196,234
	Peoples has acquired various loans through business combinations for which there was, at acquisition, evidence of deterioration of credit quality since origination and for which it was probable that all contractually required payments would not be collected. The carrying amounts of these loans included in the loan balances above are summarized as follows:
	(Dollars in thousands)	March 31,			December 31,
		2014			2013

	Net carrying amount	$	1,781		$	1,875
	Changes in the accretable yield for the three months ended March 31, 2014 were as follows:
	(Dollars in thousands)	Accretable Yield
	Balance, December 31, 2013	$	1,654
	Accretion	(268		)
	Balance, March 31, 2014	$	1,386
	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 $264.4 million and $259.1 million at March 31, 2014 and December 31, 2013, respectively. Peoples also had pledged commercial loans to secure borrowings with the FRB. The outstanding balances of these loans totaled $107.6 million and $113.0 million at March 31, 2014 and December 31, 2013, respectively.
	Nonaccrual and Past Due Loans
	A loan is considered past due if any required principal and interest payments have not been received as of the date such payments were required to be made under the terms of the loan agreement. A loan may be placed on nonaccrual status regardless of whether or not such loan is considered past due. The recorded investments in loans on nonaccrual status and accruing loans delinquent for 90 days or more were as follows:

Credit Quality Indicators
As discussed in Note 1 of the Notes to the Consolidated Financial Statements included in Peoples' 2013 Form 10-K, Peoples categorizes the majority of its loans into risk categories based upon an established risk grading matrix using a scale of 1 to 8. A description of the general characteristics of the risk grades used by Peoples is as follows:
“Pass” (grades 1 through 4): Loans in this risk category involve borrowers of acceptable-to-strong credit quality and risk who have the apparent ability to satisfy their loan obligations. Loans in this risk grade would possess sufficient mitigating factors, such as adequate collateral or strong guarantors possessing the capacity to repay the 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 of 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:

At March 31, 2014, Peoples' impaired loans shown in the table above included loans that were classified as troubled debt restructurings ("TDRs").
In assessing whether or not a borrower is experiencing financial difficulties, Peoples considers information currently available regarding the financial condition of the borrower. This information includes, but is not limited to, whether (i) the 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.
The following table summarizes the loans that were modified as a TDR during the three months ended March 31, 2014 and 2013.

Employee Benefit Plans [Text Block]	'
	Employee Benefit Plans
	Peoples sponsors a noncontributory defined benefit pension plan that covers substantially all employees hired before January 1, 2010.  The plan provides retirement benefits based on an employee’s years of service and compensation.   For employees hired before January 1, 2003, the amount of postretirement benefit is based on the employee’s average monthly compensation pay over the highest five consecutive years out of the employee’s last ten years with Peoples while an eligible employee.  For employees hired on or after January 1, 2003, the amount of postretirement benefit is based on 2% of the employee’s annual compensation plus accrued interest.  Effective January 1, 2010, the pension plan was closed to new entrants.  Effective March 1, 2011, the accrual of pension plan benefits for all participants was frozen. Peoples recognized this freeze as a curtailment as of December 31, 2010 and March 1, 2011, under the terms of the pension plan. Peoples also provides post-retirement health and life insurance benefits to former employees and directors. Only those individuals who retired before January 27, 2012 were eligible for life insurance benefits. 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 detail the components of the net periodic cost for the plans:
		Pension Benefits
		Three Months Ended
		March 31,
	(Dollars in thousands)	2014			2013
	Interest cost	$	143		$	133

	Interest cost	$	1		$	2
	Amortization of net loss	(2		)	—
	Net periodic (benefit) cost	$	(1	)	$	2
	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 first quarter of 2014, the total lump-sum distributions made to participants caused the total settlements to exceed the recognition threshold for settlement gains or losses. As a result, Peoples remeasured its pension obligation and plan assets as of January 1, 2014 as part of the calculation of the settlement loss recognized.
	The following table summarizes the change in pension obligation and funded status as a result of this remeasurement and the aggregate settlements for the three months ended March 31, 2014:
		As of			March 31, 2014

Stock-Based Compensation	'
	Stock-Based Compensation
	Under the Peoples Bancorp Inc. Second Amended and Restated 2006 Equity Plan (the “2006 Equity Plan”), Peoples may grant, among other awards, nonqualified stock options, incentive stock options, restricted stock awards, stock appreciation rights and unrestricted share awards to employees and non-employee directors. The total number of 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 shares and stock appreciation rights (“SARs”) to be settled in shares to employees and restricted shares to non-employee directors subject to the terms and conditions prescribed by the 2006 Equity Plan. In general, shares issued in connection with stock-based awards are issued from treasury shares to the extent available.  If no treasury shares are available, shares are issued from authorized but unissued 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 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 period ended March 31, 2014:
			Number of Shares Subject to Options			Weighted-Average Exercise Price			Weighted-Average Remaining Contractual Life		Aggregate Intrinsic Value
	Outstanding at January 1		57,094			$	27.96

	SARs granted to employees have an exercise price equal to the fair market value of Peoples’ shares on the date of grant and will be settled using 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 period ended March 31, 2014:

	Restricted Shares
	Under the 2006 Equity Plan, Peoples may award restricted shares to officers, key employees and non-employee directors.  In general, the restrictions on shares awarded to non-employee directors expire after six months, while the restrictions on shares awarded to employees expire after periods ranging from one to three years. In the first quarter of 2014, Peoples granted restricted 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 Peoples has net income greater than zero and maintains a well-capitalized status by regulatory standards.
	The following summarizes the changes to Peoples’ restricted shares for the period ended March 31, 2014:
