Summary Of Significant Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	NOTE 1-Summary of Significant Accounting Policies  Nature of Operations and Basis of Presentation Codorus Valley Bancorp, Inc. (“Corporation” or “Codorus Valley”) is a one-bank holding company headquartered in York, Pennsylvania that provides a full range of banking services through its subsidiary, PeoplesBank, A Codorus Valley Company (“PeoplesBank” or “Bank”). PeoplesBank operates three wholly-owned subsidiaries as of December 31, 2016. The subsidiaries consist of Codorus Valley Financial Advisors, Inc. d/b/a PeoplesWealth Advisors, which sells non-deposit investment products in Pennsylvania, SYC Settlement Services, Inc., which provides real estate settlement services, and Codorus Valley Financial Advisors, Inc. d/b/a PeoplesWealth Advisors, a subsidiary that sells non-deposit investment products in Maryland. In addition, PeoplesBank may periodically create nonbank subsidiaries for the purpose of temporarily holding foreclosed properties pending the liquidation of these properties. PeoplesBank operates under a state charter and is subject to regulation by the Pennsylvania Department of Banking and Securities, and the Federal Deposit Insurance Corporation. The Corporation is subject to regulation by the Federal Reserve Board and the Pennsylvania Department of Banking and Securities.  The consolidated financial statements include the accounts of Codorus Valley and its wholly-owned bank subsidiary, PeoplesBank, and two wholly-owned nonbank subsidiaries, SYC Realty Company, Inc. and CVLY Subsidiary Corp. SYC Realty was inactive during the reportable period of 2016. CVLY Subsidiary Corp. was the surviving merged entity resulting from the acquisition of Madison Bancorp, Inc. (“Madison”) and may be used, as needed, for the financial and legal management of future acquisition transactions. The accounts of CVB Statutory Trust No. 1 and No. 2 are not included in the consolidated financial statements as discussed in Note 8 – Short-term Borrowings and Long-term Debt. All significant intercompany account balances and transactions have been eliminated in consolidation. The accounting and reporting policies of Codorus Valley and subsidiaries conform to accounting principles generally accepted in the United States of America and have been followed on a consistent basis.  Investment Securities The classification of securities is determined at the time of acquisition and is reevaluated at each reporting date. Securities classified as available-for-sale are debt securities that the Corporation intends to hold for an indefinite period of time, but not necessarily to maturity. Any decision to sell a security classified as available-for-sale would be based on various factors, including significant movements in interest rates, changes in maturity mix of assets and liabilities, income or liquidity needs, regulatory considerations and other factors. Debt securities available-for-sale are carried at fair value, with unrealized gains and losses, net of taxes, reported as a component of accumulated other comprehensive income in shareholders' equity. Premiums and discounts are recognized in interest income using the interest method over the estimated life of the security. Realized gains and losses from the sale of available-for-sale securities are computed on the basis of specific identification of the adjusted cost of each security and are shown net as a separate line item in the statement of income.  Declines in the fair value of available-for-sale securities below their cost that are deemed to be other-than-temporary are reflected in earnings as realized losses. In estimating other-than-temporary impairment losses, management must first assess whether (a) it has the intent to sell the security and (b) it is more likely than not that it will be required to sell the security prior to its anticipated recovery. These steps are done before assessing whether the cost basis of the investment will be recovered. The assessment of the probability of recovery would consider, among other things, the length of time and the extent to which the fair value has been less than cost and the financial condition and near-term prospects of the issuer. More information about investment securities is provided in Note 3 – Securities.  Restricted Investment in Bank Stocks Restricted stock, which represents required investments in the common stock of correspondent banks, is carried at cost and, as of December 31, 2016 and 2015 consisted primarily of the common stock of the Federal Home Loan Bank of Pittsburgh (FHLBP) and, to a lesser degree, Atlantic Community Bancshares, Inc. (ACBI), the parent company of Atlantic Community Bankers Bank (ACBB). Under the FHLBP’s Capital Plan, PeoplesBank is required to maintain a minimum member stock investment, both as a condition of becoming and remaining a member and as a condition of obtaining borrowings from the FHLBP. The FHLBP uses a formula to determine the minimum stock investment, which is based on the volume of loans outstanding, unused borrowing capacity and other factors. The FHLBP paid dividends during the years ended December 31, 2016 and 2015 . The FHLBP restricts the repurchase of the excess capital stock of member banks. The amount of excess capital stock that can be repurchased from any member is currently the lesser of five percent of the member’s total capital stock outstanding or its excess capital stock outstanding.  Management evaluates the restricted stock for impairment in accordance with FASB ASC Topic 942. Management’s determination of whether these investments are impaired is based on their assessment of the ultimate recoverability of their cost rather than by recognizing temporary declines in value. Using the FHLBP as an example, the determination of whether a decline affects the ultimate recoverability of cost is influenced by criteria such as: (1) the significance of the decline in net assets of the FHLBP as compared to the capital stock amount for the FHLBP and the length of time this situation has persisted; (2) commitments by the FHLBP to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLBP; and (3) the impact of legislative and regulatory changes on institutions and, accordingly, on the customer base of the FHLBP. Management believes no impairment charge was necessary related to the restricted stock during the periods ended December 31, 2016 and 2015 . Loans Held for Sale Loans held for sale are primarily comprised of residential mortgage loans originated by the Bank. During 2016, PeoplesBank began originating loans partially guaranteed by the Small Business Administration with the intent to sell the guaranteed portion of secondary-market qualified loans. Loans held for sale are reported at the lower of cost or fair value, as determined by the aggregate commitments from investors or current investor yield requirements. The amount by which cost exceeds fair value, if any, is accounted for as a valuation allowance and is charged to expense in the period of the change. Gains or losses recognized on the sale of mortgage loans and loans guaranteed by the Small Business Administration loans are recognized based on the difference between the selling price and the carrying value of the related loan and are recorded in noninterest income.  Loans Loans receivable that management has the intent and ability to hold for the foreseeable future or until maturity or payoff, are stated at their outstanding unpaid principal balances less amounts charged off, net of an allowance for loan losses and any deferred fees or costs. Interest income is accrued on the unpaid principal balance. Generally, loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the yield (interest income) over the contractual life of the loan. The loans receivable portfolio is segmented into commercial and consumer loans. Commercial loans consist of the following industry classes: builder & developer, commercial real estate investor, residential real estate investor, hotel/motel, wholesale & retail, agriculture, manufacturing and all other. Consumer loans consist of the following classes: residential mortgage, home equity and all other.  For all classes of loans receivable, the accrual of interest is discontinued when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about further collectability of principal or interest, even though the loan is currently performing. A loan may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. When a loan is placed on nonaccrual status, unpaid interest credited to income in the current year is reversed and unpaid interest accrued in prior years is charged against the allowance for loan losses. Interest received on nonaccrual loans, including impaired loans, generally is either applied against principal or reported as interest income, according to the Corporation’s judgment as to the collectability of principal. Generally, loans are restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time, generally six months, and the ultimate collectability of the total contractual principal and interest is no longer in doubt. The past due status of all classes of loans receivable is determined based on contractual due dates for loan payments.  Acquired Loans Acquired loans are initially recorded at their acquisition date fair values. The carryover of allowance for loan losses is prohibited as any credit losses in the loans are included in the determination of the fair value of the loans at the acquisition date. Fair values for acquired loans are based on a discounted cash flow methodology that involves assumptions and judgments as to credit risk, prepayment risk, liquidity risk, default rates, loss severity, payment speeds, collateral values and discount rate.  For acquired loans that are not deemed impaired at acquisition, credit discounts representing principal losses expected over the life of the loan are a component of the initial fair value and amortized over the life of the asset. Subsequent to the acquisition date, the methods used to estimate the required allowance for loan losses on these loans is similar to originated loans. However, the Corporation records a provision for loan losses only when the required allowance for loan losses exceeds any remaining credit discount. The remaining differences between the acquisition date fair value and the unpaid principal balance at the date of acquisition are recorded in interest income over the life of the loan.  Acquired loans that have evidence of deterioration in credit quality since origination and for which it is probable, at acquisition, that the Corporation will be unable to collect all contractually required payments are accounted for as impaired loans under ASC 310-30. The excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable discount and is recognized into interest income over the remaining life of the loans. The difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is referred to as the non-accretable discount. The non-accretable discount represents estimated future credit losses expected to be incurred over the life of the loan. Subsequent decreases to the expected cash flows require the Corporation to evaluate the need for an allowance for loan losses on these loans. Subsequent improvements in expected cash flows result in the reversal of a corresponding amount of the non-accretable discount which the Corporation then reclassifies as an accretable discount that is recognized into interest income over the remaining life of the loans using the interest method.  The following is a summary of acquired impaired loans from the merger, as discussed in Note 20-Merger With Madison Bancorp, Inc.:     (dollars in thousands) January 16, 2015  Contractually required principal and interest at acquisition $ 1,961  Contractual cash flows not expected to be collected 1,185  Expected cash flows at acquisition 776  Interest component of expected cash flows 160  Basis in acquired loans at acquisition - estimated fair value $ 616  Allowance for Loan Losses The allowance for loan losses represents the Corporation’s estimate of losses inherent in the loan portfolio as of the balance sheet date and is recorded as a reduction to loans. The allowance for loan losses is increased by the provision for loan losses, and decreased by charge-offs, net of recoveries. Loans deemed to be uncollectable are charged against the allowance for loan losses, and subsequent recoveries, if any, are credited to the allowance. All, or part, of the principal balance of loans receivable are charged off to the allowance as soon as it is determined that the repayment of all, or part, of the principal balance is highly unlikely. While the Corporation attributes a portion of the allowance to individual loans and groups of loans that it evaluates and determines to be impaired, the allowance is available to cover all charge-offs that arise from the loan portfolio.  The allowance for loan losses is maintained at a level considered adequate to provide for losses that can be reasonably anticipated. The Corporation performs a quarterly evaluation of the adequacy of the allowance. The allowance is based on the Corporation’s past loan loss experience, known and inherent risks in the portfolio, adverse situations that may affect the borrower’s ability to repay, the estimated value of any underlying collateral, composition of the loan portfolio, current economic conditions and other relevant factors. This evaluation is inherently subjective as it requires material estimates that may be susceptible to significant revision as more information becomes available. The allowance consists of specific, general and unallocated components. The specific component relates to loans that are classified as impaired, generally substandard and nonaccrual loans. For loans that are classified as impaired, an allowance is established when the collateral value (or discounted cash flows or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers pools of loans by loan class including commercial loans not considered impaired, as well as smaller balance homogeneous loans, such as residential real estate, home equity and other consumer loans. These pools of loans are evaluated for loss exposure based upon historical loss rates for each of these classes of loans, adjusted for qualitative (environmental) risk factors. Historical loss rates are based on a two year rolling average of net charge-offs. Qualitative risk factors that supplement historical losses in the evaluation of loan pools are shown below. Each factor is assigned a value to reflect improving, stable or declining conditions based on the Corporation’s best judgment using relevant information available at the time of the evaluation.  ·  Changes in national and local economies and business conditions ·  Changes in the value of collateral for collateral dependent loans  ·  Changes in the level of concentrations of credit ·  Changes in the volume and severity of classified and past due loans ·  Changes in the nature and volume of the portfolio ·  Changes in collection, charge-off, and recovery procedures ·  Changes in underwriting standards and loan terms ·  Changes in the quality of the loan review system ·  Changes in the experience/ability of lending management and key lending staff ·  Regulatory and legal regulations that could affect the level of credit losses ·  Other pertinent environmental factors  The unallocated component is maintained to cover uncertainties that could affect the Corporation’s estimate of probable losses. For example, increasing credit risks and uncertainties, not yet reflected in current leading indicators, associated with prolonged low economic growth, or recessionary business conditions for certain industries or the broad economy, or the erosion of real estate values, represent risk factors, the occurrence of any or all of which can adversely affect a borrowers’ ability to service their loans. The unallocated component of the allowance also reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the loan portfolio, including the unpredictable timing and amounts of charge-offs and related historical loss averages, and specific-credit or broader portfolio future cash flow value and collateral valuation uncertainties which could negatively impact unimpaired portfolio loss factors.  As disclosed in Note 4-Loans, the Corporation engages in commercial and consumer lending. Loans are made within the Corporation’s primary market area and surrounding areas, and include the purchase of whole loan or participation interests in loans from other financial institutions. Commercial loans, which pose the greatest risk of loss to the Corporation, whether originated or purchased, are generally secured by real estate. Within the broad commercial loan segment, the builder & developer and commercial real estate investor loan classes generally present a higher level of risk than other commercial loan classifications. This greater risk is due to several factors, including the concentration of principal in a limited number of loans and borrowers, the effect of general economic conditions on income producing properties, unstable real estate prices and the dependency upon successful construction and sale or operation of the real estate project. Within the consumer loan segment, junior (i.e., second) liens present a slightly higher risk to the Corporation because economic and housing market conditions can adversely affect the underlying value of the collateral and the ability of some borrowers to service their debt.  A loan is considered impaired when, based on current information and events, it is probable that the Corporation will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered in determining impairment include payment status and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. The Corporation determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. Loans that are deemed impaired are evaluated for impairment loss based on the net realizable value of the collateral, as applicable. Loans that are not collateral dependent will rely on the present value of expected future cash flows discounted at the loan’s effective interest rate to determine impairment loss. Large groups of smaller balance homogeneous loans such as residential mortgage loans, home equity loans and other consumer loans are collectively evaluated for impairment, unless they are classified as impaired.  An allowance for loan losses is established for an impaired commercial loan if its carrying value exceeds its estimated fair value. For commercial loans secured by real estate, estimated fair values are determined primarily through third-party appraisals of the underlying collateral. When a real estate secured loan becomes impaired, a decision is made regarding whether an updated certified appraisal of the real estate is necessary. This decision is based on various considerations, including the age of the most recent appraisal, the loan-to-value ratio based on the most recent appraisal and the condition of the property. Appraisals are generally discounted to provide for selling costs and other factors to determine an estimate of the net realizable value of the property. For commercial loans secured by non-real estate collateral, such as accounts receivable, inventory and equipment, estimated fair values are determined based on the borrower’s financial statements, inventory reports, accounts receivable aging or equipment appraisals or invoices. Indications of value from these sources are generally discounted based on the age of the financial information or the quality of the assets. In instances when specific consumer related loans become impaired, they may be partially or fully charged off, which obviates the need for a specific allowance.  Loans whose terms are modified are classified as troubled debt restructurings if the Corporation grants borrowers experiencing financial difficulties concessions that it would not otherwise consider. Concessions granted under a troubled debt restructuring may involve an interest rate that is below the market rate given the associated credit risk of the loan or an extension of a loan’s stated maturity date. Loans classified as troubled debt restructurings are designated as impaired. Non-accrual troubled debt restructurings are restored to accrual status if principal and interest payments, under the modified terms, are current for a reasonable period of time, generally six consecutive months after modification and future payments are reasonably assured. Banking regulatory agencies, as an integral part of their examination process, periodically review the Corporation’s allowance for loan losses and may require the Corporation to recognize additions to the allowance based on their judgments about information available to them at the time of their examination, which may not be currently available to the Corporation. Based on a comprehensive analysis of the loan portfolio, the Corporation believes that the level of the allowance for loan losses at December 31, 2016 is adequate.  Transfers of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Corporation, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Corporation does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Premises and Equipment Land is carried at cost. Premises and equipment are carried at cost less accumulated depreciation. Depreciation expense is calculated principally on the straight-line method over the assets’ estimated useful lives. Estimated useful lives are five to forty years for buildings and improvements, five to twenty years for furniture and equipment and two to seven years for computer equipment and software. Maintenance and repairs are charged to expense as incurred. The cost of significant improvements to existing assets is capitalized and amortized over the shorter of the asset’s useful life or related lease term. When facilities are retired or otherwise disposed of, the depreciated cost is removed from the asset accounts, and any gain or loss is reflected in the statement of income.  Foreclosed Real Estate Foreclosed real estate, included in other assets, is comprised of property acquired through a foreclosure proceeding or property that is acquired through in substance foreclosure. Foreclosed real estate is initially recorded at fair value minus estimated costs to sell at the date of foreclosure, establishing a new cost basis. Any difference between the carrying value and the new cost basis is charged against the allowance for loan losses. Appraisals, obtained from an independent third party, are generally used to determine fair value. After foreclosure, management reviews valuations at least quarterly and adjusts the asset to the lower of cost or fair value minus estimated costs to sell through a valuation allowance or a charge-off. Costs related to the improvement of foreclosed real estate are generally capitalized until the real estate reaches a saleable condition subject to fair value limitations. Revenue and expense from operations and changes in the valuation allowance are included in noninterest expense. When a foreclosed real estate asset is ultimately sold, any gain or loss on the sale is included in the income statement as a component of noninterest expense. At December 31, 2016 , foreclosed real estate, net of allowance, was $2,705,000 , compared to $2,913,000 for December 31, 2015 . Included within loans receivable as of December 31, 2016, was a recorded investment of $230,000 of consumer mortgage loans secured by residential real estate properties, for which formal foreclosure proceedings were in process according to local requirements of the applicable jurisdiction.  Investments in Real Estate Partnerships In March 2003, PeoplesBank acquired a 73.47 percent limited partner interest in a real estate joint venture known as Village Court, which was formed to develop, construct, own and operate a 60 -unit affordable housing complex located in Dover Township, York County, Pennsylvania. Construction of the housing complex was completed in the fourth quarter of 2004 and the complex was fully leased by December 31, 2004. The investment balance included in other assets has been fully amortized as of December 31, 2016 and 2015 .  Investment and related tax credits are accounted for under the effective yield method of accounting under which tax credits are recognized as they are allocated, and the cost of the investment is amortized to provide a constant yield over the period that tax credits are allocated, generally ten years.  Bank Owned Life Insurance PeoplesBank invests in bank owned life insurance (BOLI) as a source of funding for employee benefit expenses. BOLI involves the purchasing of life insurance by PeoplesBank on a select group of employees and directors. PeoplesBank is the owner and beneficiary of the policies. This life insurance investment is carried at the cash surrender value of the underlying policies and is included in other assets in the amount of $31,621,000 at December 31, 2016 , compared to $23,980,000 at December 31, 2015 .  Mortgage Servicing Rights PeoplesBank retained servicing of sold mortgage loans beginning in 2016. The mortgage servicing rights (MSRs) associated with the sold loans are included in other assets on the consolidated balance sheets at an amount equal to the estimated fair value of the contractual rights to service the mortgage loans. The MSR asset is amortized as a reduction to servicing income. The MSR asset is evaluated periodically for impairment and carried at the lower of amortized cost or fair value. A third party calculates fair value by discounting the estimated cash flows from servicing income using a rate consistent with the risk associated with these assets and an expected life commensurate with the expected life of the underlying loans. In the event that the amortized cost of the MSR asset exceeds the fair value of the asset, a valuation allowance would be established through a charge against servicing income. Subsequent fair value evaluations may determine that impairment has been reduced or eliminated, in which case the valuation allowance would be reduced through a credit to earnings. At December 31, 2016, the MSR asset was $324,000 and the balance of residential mortgage loans serviced for third parties was $36,969,000 . As December 31, 2015, there were no MSR assets.  Trust and Investment Services Assets Assets held by PeoplesBank in a fiduciary or agency capacity for its clients are not included in the consolidated balance sheets since these items are not assets of PeoplesBank.  Advertising Advertising costs are charged to expense when incurred.  Income Taxes Deferred income taxes are provided on the liability method whereby deferred tax assets are recognized for deductible temporary differences and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax basis. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted through the provision for income taxes for the effects of changes in tax laws and rates on the effective date.  The Corporation accounts for uncertain tax positions as required by FASB ASC Topic 740. FASB ASC Topic 740 clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements. Specifically, the accounting standard prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return as well as guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. No significant income tax uncertainties have been identified by the Corporation; therefore, the Corporation recognized no adjustment for unrecognized income tax benefits for the years ended December 31, 2016 and 2015. The Corporation’s policy is to recognize interest and penalties on unrecognized tax benefits in income taxes expense in the Consolidated Statement of Income. The Corporation did no t recognize any interest and penalties for the years ended December 31, 2016 , 2015 and 2014 . The tax years subject to examination by the taxing authorities are the years ended December 31, 2015 , 2014 , and 2013 .  Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America 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. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the evaluation of other-than-temporary impairment losses for investment securities and the evaluation of impairment losses for foreclosed real estate.  Fair Value of Financial Instruments Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in Note 16 – Fair Value Measurements and Fair Values of Financial Instruments. Fair value estimates involve uncertainties and matters of significant judgment. Changes in assumptions or in market conditions could significantly affect the estimates.  Goodwill and Core Deposit Intangible Assets Goodwill arising from acquisitions is not amortized, but is subject to an annual impairment test. This test consists of a qualitative analysis. If the Corporation determines events or circumstances indicate that it is more likely than not that goodwill is impaired, a quantitative analysis must be completed. Analyses may also be performed between annual tests. Significant judgment is applied when goodwill is assessed for impairment. This judgment includes developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables, incorporating general economic and market conditions, and selecting an appropriate control premium. The Corporation completes its annual goodwill impairment test on October 1 st of each year. Based upon the analysis, the Corporation concluded that the amount of recorded goodwill was not impaired as of October 1, 2016.  Core deposit intangibles represent the value assigned to demand, interest checking, money market, and savings accounts acquired as part of an acquisition. The core deposit intangible value represents the future economic benefit of potential cost savings from acquiring core deposits as part of an acquisition compared to the cost of alternative funding sources and the alternative cost to grow a similar core deposit base. The core deposit intangible asset resulting from the merger with Madison Bancorp, Inc. was determined to ha

Securities	NOTE 3-Securities  A summary of securities, available-for-sale at December 31, 2016 and 2015 , is provided below. The securities available-for-sale portfolio is generally comprised of high quality debt instruments, such as obligations of the United States government or agencies thereof and investments in the obligations of states and municipalities. The majority of municipal bonds in the portfolio are general obligation bonds, which can draw upon multiple sources of revenue, including taxes, for payment. Only a few bonds are revenue bonds, which are dependent upon a single revenue stream for payment, but they are for critical services such as water and sewer. In many cases, municipal debt issues are insured or, in the case of school districts of selected states, backed by specific loss reserves. At December 31, 2016 , the fair value of the municipal bond portfolio was concentrated in the state of Pennsylvania at 72 percent.

The analysis considers, among other factors: 1) whether the Corporation has the intent to sell its securities prior to market recovery or maturity; 2) whether it is more likely than not that the Corporation will be required to sell its securities prior to market recovery or maturity; 3) default rates/history by security type; 4) third-party securities ratings; 5) third-party guarantees; 6) subordination; 7) payment delinquencies; 8) nature of the issuer; and 9) current financial news.  The Corporation believes that any unrealized losses at December 31, 2016 were primarily the result of changes in market interest rates and that it has the ability to hold these investments for a time necessary to recover the amortized cost. Through December 31, 2016 , the Corporation has collected all interest and principal on its investment securities as scheduled. The Corporation believes that collection of the contractual principal and interest is probable and, therefore, all impairment is considered to be temporary.

Loans [Abstract]
Loans	NOTE 4-Loans Loan Portfolio Composition  The table below provides the composition of the loan portfolio at December 31, 2016 and 2015 . The portfolio is comprised of two segments, commercial and consumer loans. The commercial loan segment is disaggregated by industry class which allows the Corporation to monitor risk and performance. Those industries representing the largest dollar investment and most risk are listed separately. The “O ther ” commercial loans category is comprised of various industries. The consumer related segment is comprised of residential mortgages, home equity and other consumer loans. The Corporation has not engaged in sub-prime residential mortgage originations.     December 31, % Total December 31, % Total  (dollars in thousands) 2016 Loans 2015 Loans  Builder & developer $ 148,635 11.7 $ 133,978 11.9  Commercial real estate investor 243,623 19.2 191,994 17.1  Residential real estate investor 183,623 14.4 161,144 14.3  Hotel/Motel 82,085 6.5 84,171 7.5  Wholesale & retail 88,062 6.9 77,694 6.9  Manufacturing 32,616 2.6 30,325 2.7  Agriculture 51,848 4.1 41,217 3.7  Other 242,872 19.1 215,891 19.2  Total commercial related loans 1,073,364 84.5 936,414 83.4  Residential mortgages 73,496 5.8 70,094 6.2  Home equity 94,222 7.4 86,408 7.7  Other 29,689 2.3 30,295 2.7  Total consumer related loans 197,407 15.5 186,797 16.6  Total loans $ 1,270,771 100.0 $ 1,123,211 100.0  Concentrations of Credit Risk  Concentrations of credit risk arise when a number of c lient s are engaged in similar business activities in the same geographic region or have similar economic features that could cause their ability to meet contractual obligations to be similarly affected by changes in economic conditions. Most of the Corporation's business is with c lient s in York County, Pennsylvania and northern-central Maryland, specifically Baltimore, Harford and Carroll counties. Although this focus may pose a concentration risk geographically, the Corporation believes that the diverse local economy and our detailed knowledge of the c lient base lessens this risk. At December 31, 2016 , the Corporation had three industry concentrations that exceeded 10 percent of the total loan portfolio : commercial real estate investor, which represented 19.2 percent of the portfolio; residential real estate investor, which represented 14.4 percent of the portfolio; and builder & developer, which represented 11.7 percent of the portfolio. At December 31, 2015 , the Corporation had three industry concentrations that exceeded 10 percent of the total loan portfolio : commercial real estate investor, which represented 17.1 percent of the portfolio; residential real estate investor, which represented 14.3 percent of the portfolio; and builder & developer, which represented 11.9 percent of the portfolio. Loans to borrowers within these industries are usually collateralized by real estate.  The principal balance of outstanding loans to directors, executive officers, principal shareholders and any a ffiliates of such persons was $162,000 at December 31, 2016 and $129,000 at December 31, 2015 . During 2016 , total additions were $170,000 and total repayments and reductions were $137,000 . As of year-end 2016 , all loans to this group were current and performing in accordance with contractual terms.  Loan Risk Ratings  The Corporation’s internal risk rating system follows regulatory guidance as to risk classifications and definitions. Every approved loan is assigned a risk rating. Generally, risk ratings for commercial related loans and residential mortgages held for investment are determined by a formal evaluation of risk factors performed by the Corporation’s underwriting staff. For consumer loans, and commercial loans up to $500,000 , the Corporation uses third-party credit scoring software models for risk rating purposes. The loan portfolio is monitored on a continuous basis by loan officers, loan review personnel and senior management. Adjustments of loan risk ratings are generally performed by the Special Asset Committee, which includes senior management. The Committee, which typically meets monthly, makes changes, as appropriate, to risk ratings when it becomes aware of credit events such as payment delinquency, cessation of a business or project, bankruptcy or death of the borrower, or changes in collateral value.  The Corporation uses ten risk ratings to grade loans. The first seven ratings, representing the lowest risk, are combined and given a “pass” rating. A pass rating is a satisfactory credit rating, which applies to a loan that is expected to perform in accordance with the loan agreement and has a low probability of loss. A loan rated “special mention” has a potential weakness which may, if not corrected, weaken the loan or inadequately protect the Corporation’s position at some future date. A loan rated “substandard” is inadequately protected by the current net worth or paying capacity of the borrower, or of the collateral pledged. A “substandard” loan has a well-defined weakness or weaknesses that could jeopardize liquidation of the loan, which exposes the Corporation to loss if the deficiencies are not corrected. When circumstances indicate that collection of the loan is doubtful, the loan is risk-rated “nonaccrual,” the accrual of interest income is discontinued, and any unpaid interest previously credited to income is reversed.

Generally, impaired loans are loans risk rated substandard and nonaccrual or classified as troubled debt restructurings . An allowance is established for those individual loans that are commercial related where the Corporation has doubt as to full recovery of the outstanding principal balance. Typically, impaired consumer related loans are partially or fully charged-off eliminating the need for a specific allowance. The recorded investment represents outstanding unpaid principal loan balances adjusted for charge-offs.

Concessions granted with respect to these loans involve an extension of the maturity date or a below market interest rate relative to new debt with similar credit risk. Generally, these loans are secured by real estate. If repayment of the loan is determined to be collateral dependent, the loan is evaluated for impairment loss based on the fair value of the collateral. For loans that are not collateral dependent, the present value of expected future cash flows, discounted at the loan’s original effective interest rate, is used to determine any impairment loss. A nonaccrual TDR represents a nonaccrual loan, as previously defined, which includes an economic concession. Nonaccrual TDRs are restored to accrual status if principal and interest payments, under the modified terms, are current for six consecutive payments after the modification and future principal and interest payments are reasonably assured. In contrast, an accruing TDR represents a loan that, at the time of the modification, has a demonstrated history of payments and with respect to which management believes that future loan payments are reasonably assured under the modified terms.  There were no loans whose terms have been modified under TDRs during the years ended December 31, 2016 and 2015. There were no defaults during the year ended December 31, 2016 for TDRs entered into during the previous 12 month period.

Regulatory Matters [Abstract]
Regulatory Matters	NOTE 9-Regulatory Matters  The Corporation is subject to restrictions on the payment of dividends to its shareholders pursuant to the Pennsylvania Business Corporation Law of 1988, as amended (“BCL”). The BCL prohibits dividend payments if such payment would render the Corporation insolvent or result in negative net worth. Federal and state banking regulations place certain restrictions on dividends paid and loans or advances made by PeoplesBank to the Corporation. The amount of total dividends, which may be paid at any date, is generally limited to the retained earnings of PeoplesBank. Furthermore, dividend payments would be prohibited if the effect thereof would cause PeoplesBank’s capital to be reduced below applicable minimum capital requirements as discussed below. Loans and advances by PeoplesBank to affiliates, including the Corporation, are limited to 10 percent of PeoplesBank’s capital stock and contributed capital on a secured basis.  The Corporation and PeoplesBank are subject to various regulatory capital requirements. Failure to meet minimum capital requirements can result in certain mandatory and possible additional discretionary actions by regulators that, if imposed, could have a material effect on the Corporation’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Corporation and PeoplesBank must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators.  On July 2, 2013, the Board of Governors of the Federal Reserve System finalized its rule implementing the Basel III regulatory capital framework, which the FDIC adopted on July 9, 2013. Under the rule, minimum requirements increased both the quantity and quality of capital held by banking organizations. Consistent with the Basel III framework, the rule included a new minimum ratio of common equity Tier 1 capital to risk-weighted assets of 4.5 percent, and a common equity Tier 1 conservation buffer of 2.5 percent of risk-weighted assets, that applies to all supervised financial institutions, which is to be phased in over a four year period beginning January 1, 2016, with the full 2.5 percent required as of January 1, 2019. The rule also raised the minimum ratio of Tier 1 capital to risk-weighted assets from 4 percent to 6 percent, and includes a minimum leverage ratio of 4 percent for all banking organizations. The new rule also increased the risk weights for past-due loans, certain commercial real estate loans, and some equity exposures, and makes selected other changes in risk weights and credit conversion factors. The rule for smaller, less complex institutions, including the Corporation, took effect January 1, 2015.  Quantitative measures established by regulators to ensure capital adequacy require the Corporation and PeoplesBank to maintain minimum ratios, as set forth below, to total and Tier 1 capital as a percentage of risk-weighted assets, and of Tier 1 capital to quarter-to-date average assets (leverage ratio). In December 2016 , PeoplesBank received the most recent notification from the Federal Deposit Insurance Corporation, which categorized PeoplesBank as “well capitalized”, as of September 30, 2016 , under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes would change PeoplesBank’s well capitalized category. As of December 31, 2015 , PeoplesBank was also categorized as “well capitalized”.

On December 23, 2015, the Corporation announced that the underwriters of the previously closed public offering had exercised in full their option to purchase an additional 227,850 shares of the Corporation’s common stock at a public offering price of $19.75 per share.

Approximately $19,800,000 of the net proceeds from the public offering were invested in the Corporation’s Bank subsidiary, PeoplesBank. A portion of the proceeds were used to redeem the remaining $12,000,000 of Series B preferred held by the United States Department of Treasury on February 18, 2016. The remaining proceeds were used for general corporate purposes.  Private Placement of Common Stock  On March 26, 2014, the Corporation completed a private placement of 650,000 shares of its common stock at a price of $20.00 per share, par value $2.50 per share, pursuant to the terms of a Securities Purchase Agreement (“Purchase Agreement”) dated March 26, 2014, by and among the Corporation and seven accredited investors.

This registration statement was filed with the SEC on April 25, 2014. The full text and form of both the Purchase Agreement and the Registration Rights Agreement are attached to the Corporation’s related Form 8-K filed on March 27, 2014.  The Corporation raised net proceeds of approximately $12,500,000 resulting from the gross amount of the private placement transaction of $13,000,000 , less related issuance costs of approximately $500,000 . The Corporation used the net proceeds from the private placement, and additional cash, to redeem $13,000,000 of the $25,000,000 in outstanding shares of the Corporation’s preferred stock held by the United States Department of the Treasury.  Preferred Stock Issued under the US Treasury’s Small Business Lending Fund Program  The U.S. Department of the Treasury (“Treasury”) had a capital investment in the Corporation pursuant to the Corporation’s participation in the Treasury’s Small Business Lending Funding Program (“SBLF Program”). In August 2011, the Corporation sold to the Treasury, for an aggregate purchase price of $25,000,000 , 25,000 shares of non-cumulative, perpetual preferred stock, Series B, $1,000 liquidation value, $2.50 par value. On May 30, 2014, the Corporation redeemed 13,000 of the 25,000 outstanding shares of the Corporation’s preferred stock that had been issued to the Treasury, leaving 12,000 outstanding shares representing $12,000,000 of preferred stock. On February 18, 2016, the Corporation redeemed the remaining $12,000,000 of Series B preferred stock issued to the Treasury as reported on Form 8-K filed on February 19, 2016.  The annualized dividend rate on the preferred stock issued under the SBLF Program was 1 percent for the periods ended December 31, 2015 and 2014, and through the redemption date of February 18, 2016.  Common Stock Dividend  Periodically, the Corporation distributes stock dividends on its common stock. The Corporation distributed 5 percent common stock dividends on December 13, 2016 and December 8, 2015 which resulted in the issuance of 398,541 and 294,161 additional common shares, respectively.

Benefit Plans [Abstract]
Benefit Plans	 NOTE 11- Benefit Plans  Defined Contribution Plan PeoplesBank maintains a 401(k) savings and investment plan covering substantially all employees. Under the plan, employees can contribute a percentage of their compensation subject to certain limits based on federal tax law . In 2016, 2015, and 2014, Peoples Bank made 100 percent matching contributions up to the first 4 percent of each employee’s compensation contributed to the plan, and both the employee and employer contributions vest immediately. Peoples Bank's expense for the 401(k) savings and investment plan was $522,000 for 2016, $461,000 for 2015 and $398,000 for 2014.

Stock-Based Compensation [Abstract]
Stock-Based Compensation	 NOTE 12-Stock-Based Compensation  FASB ASC Topic 718 requires that the fair value of equity awards granted to employees be recognized as compensation expense over the period during which an employee is required to provide service in exchange for such awards.  The Corporation early adopted ASU 2016-09 in 2016, which provides improvements to the accounting for employee share-based payments. See Note 1 – Summary of Significant Accounting Policies for additional information.  The following table presents information about the Corporation’s stock plans, adjusted for stock dividends distributed, as of December 31, 2016 .

(3) Amount includes 46,614 of unvested options.  2000 Stock Incentive Plan and 2007 Long-Term Incentive Plan (LTIP)  Options awarded under these plans to date have been granted with an exercise price equal to the fair value of the stock on the grant date, a minimum vesting period of six months and an expiration period of ten years. Restricted awards are granted at fair value. All of the restricted shares granted in 2016 and 15,290 of the restricted shares granted in 2015 vest as follows: 1/3 rd at the end of the first year from the date of grant; 1/3 rd at the end of the second year from the date of grant; and 1/3 rd at the end of the third year from the date of grant. The remaining 2,268 restricted shares granted in 2015 and all restricted shares granted during 2014 vest as follows: 0% at the end of the first year from the date of grant; 50% at the end of the second year from the date of grant; and 50% at the end of the third year from the date of grant. Upon exercise and/or award, the Corporation has historically issued authorized, but unissued, common stock to satisfy the options/awards.  The following table presents compensation expense and related tax benefits for stock option and restricted stock awards recognized on the consolidated statement of income.     (dollars in thousands) 2016 2015 2014  Compensation expense $ 491 $ 325 $ 256  Tax benefit (164) (78) (61)  Net income effect $ 327 $ 247 $ 195  The tax benefit shown in the preceding table is less than the benefit that would be calculated using the Corporation’s 35% statutory Federal tax rate. Under FASB ASC Topic 718, tax benefits are only recognized over the vesting period for options that ordinarily will generate a tax deduction when exercised (non-qualified stock options) and restricted stock awards.  The Corporation granted the following stock options and restricted stock awards during the years ended December 31, 2016 , 2015 and 2014 .     2016 2015 2014  Nonqualified stock options 21,723 70,184 11,846  Incentive stock options 0 5,185 22,645  Restricted stock 20,837 17,558 9,840  The weighted average grant-date fair value and weighted average assumptions used to determine the fair value using the Black-Scholes valuation model for the stock options granted are presented below.     2016 2015 2014  Fair value $ 3.64 $ 4.22 $ 5.42  Expected life (in years) 4.5 5.2 5.5  Risk-free interest rate 1.57 % 1.64 % 1.56 %  Expected volatility 24.31 % 28.22 % 36.01 %  Expected dividend yield 2.42 % 2.59 % 2.33 %    The expected life of the options was estimated based on historical behavior and represents the period of time that options granted are expected to be outstanding. The risk-free interest rate is the U.S. Treasury rate commensurate with the expected life of the options on the grant date. Volatility of the Corporation’s stock price was based on historical volatility for the period commensurate with the expected life of the options. Dividend yield was based on dividends for the most current year divided by the average market price for the most current year.

The unrecognized compensation expense does not include an estimate for forfeiture of stock awards. The Corporation recognizes forfeitures in the period in which the forfeiture occurs.  Employee Stock Purchase Plan (ESPP)  Under the ESPP, eligible employees can purchase common stock of the Corporation at 85% of the fair market value of the stock at the beginning or end of the six-month offering period, whichever is lower. The ESPP is considered to be a compensatory plan. The following table presents information about the ESPP for the years ended December 31, 2016 , 2015 and 2014 .     2016 2015 2014  ESPP shares purchased 9,897 7,716 7,710  Average purchase price per share ( 85% of market value) $ 16.860 $ 16.530 $ 16.776  Compensation expense recognized (in thousands) $ 34 $ 33 $ 32  Shares issued from treasury stock to satisfy the purchase of ESPP shares 1,416 990 940  Shares issued from authorized but unissued common stock  to satisfy the purchase of ESPP shares 8,481 6,726 6,770  Employee Stock Bonus Plan (ESBP)  The ESBP is administered by the Compensation Committee which is comprised of non-employee members of the Corporation’s Board of Directors.

Commitments To Extend Credit [Abstract]
Commitments To Extend Credit	NOTE 14-Commitments to Extend Credit  In the normal course of business, the Corporation is a party to various financial transactions that are not funded as of the balance sheet date. Off-balance sheet financial instruments, which enable PeoplesB ank c lient s to meet their financing needs, are comprised mainly of commitments to extend credit and standby letters of credit. Standby letters of credit are written conditional commitments issued by PeoplesBank to guarantee the performance of a c lient to a third party. The credit and market risk involved in issuing letters of credit is essentially the same as that involved in extending other loan commitments. To manage these risks, the Corporation uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments and requires collateral to support these letters of credit as deemed necessary. Management believes that the proceeds obtained through a liquidation of such collateral would be sufficient to cover the maximum potential amount of future payments required under the corresponding guarantees. The amount of the liability as of December 31, 201 6 and 201 5 , for guarantees under standby letters of credit issued was considered not material by management. Normally, commitments to extend credit and letters of credit have fixed expiration dates or termination clauses, have specific rates and are for specific purposes. Many of the commitments are expected to expire without being extended; therefore, total commitment amounts do not necessarily represent future cash requirements.  A summary of outstanding commitments at December 31, 2016 and 2015 is shown below.     (dollars in thousands) 2016 2015  Commitments to grant loans  Fixed rate $ 104,274 $ 35,706  Variable rate 27,369 34,791   Unfunded commitments of existing loans  Fixed rate $ 68,571 $ 49,818  Variable rate 229,459 181,883   Standby letters of credit $ 19,505 $ 19,037

Fair Value Measurements And Fair Values Of Financial Instruments [Abstract]
Fair Value Measurements And Fair Values Of Financial Instruments	Note 16 - Fair Value Measurements and Fair Values of Financial Instruments  The Corporation uses its best judgment in estimating the fair value of the Corporation’s assets and liabilities; however, there are inherent weaknesses in any estimation technique. Therefore, the fair value estimates herein are not necessarily indicative of the amounts that could be realized in sales transactions on the dates indicated. The estimated fair value amounts have been measured as of their respective period-ends and have not been re-evaluated or updated for purposes of these financial statements subsequent to those respective dates. As such, the estimated fair values subsequent to the respective reporting dates may be different than the amounts reported at each period end.  Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for an asset or liability in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date. GAAP establishes a fair value hierarchy that prioritizes the use of inputs used in valuation methodologies into the following three levels:  Level 1: Inputs to the valuation methodology are quoted prices, unadjusted, for identical assets or liabilities in active markets. A quoted price in an active market provides the most reliable evidence of fair value and shall be used to measure fair value whenever available.  Level 2: Inputs to the valuation methodology include quoted prices for similar assets or liabilities in active markets; inputs to the valuation methodology include quoted prices for identical or similar assets or liabilities in markets that are not active; or inputs to the valuation methodology that utilize model-based techniques for which all significant assumptions are observable in the market.  Level 3: Inputs to the valuation methodology are unobservable and significant to the fair value measurement; inputs to the valuation methodology that utilize model-based techniques for which significant assumptions are not observable in the market; or inputs to the valuation methodology that require significant management judgment or estimation, some of which may be internally developed.  Since management maximizes the use of observable inputs and minimizes the use of unobservable inputs when determining fair value, an asset’s or liability’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Management reviews and updates the fair value hierarchy classifications on a quarterly basis.  Assets Measured at Fair Value on a Recurring Basis  Securities Available for Sale  The fair values of investment securities were measured using information from a third-party pricing service. The pricing service uses quoted market prices on nationally recognized securities exchanges (Level 1), or matrix pricing (Level 2), which is a mathematical technique, used widely in the industry to value debt securities without relying exclusively on quoted market prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted prices. At least annually, the Corporation reviews a random sample of the pricing information received from the third-party pricing service by comparing it to price quotes from third-party brokers. Historically, price deviations have been immaterial.

Fair value is generally determined based upon independent third-party appraisals of the properties, or discounted cash flows based upon the expected proceeds. These loans are included as Level 3 fair values, based on the lowest level of input that is significant to the fair value measurements. At December 31, 2016 , the fair value consists of impaired loan balances of $604,000 , net of valuation allowances of $681,000 and charge-offs of $170,000 , compared to impaired loan balances of $1,846,000 , net of valuation allowances of $405,000 and charge-offs of $1,262,000 , at December 31, 2015 .  Foreclosed Real Estate Other real estate property acquired through foreclosure is initially recorded at fair value of the property at the transfer date less estimated selling cost. Subsequently, other real estate owned is carried at the lower of its carrying value or the fair value less estimated selling cost. Fair value is usually determined based upon an independent third-party appraisal of the property or occasionally upon a recent sales offer. At Decemb er 31, 2016 , the fair value of foreclosed real estate with a valuation allowance or write-down was $1,594,000 , which is net of valuation allowances of $881,000 and no write- downs. At December 31, 2015 , the fair value of foreclosed real estate with a valuation allowance or write-down was $1,846,000 , which is net of valuation allowances of $405,000 and write-downs of $1,262,000 .  Mortgage Servicing Rights Mortgage servicing rights are initially recorded at fair value upon the sale of residential mortgage loans to secondary market investors. The fair value of servicing rights is based on the present value of estimated future cash flows on pools of mortgages stratified by rate and original time to maturity. Mortgage servicing rights are subsequently evaluated for impairment on a quarterly basis. Significant inputs to the valuation include expected cash flow, expected net servicing income, a cash flow discount rate and the expected life of the underlying loans. At December 31, 2016, the fair value of the mortgage servicing rights asset was $367,000 . There were no mortgage servicing assets as of December 31, 2015.

The range of liquidation expenses and other appraisal  adjustments are presented as a percent of the appraisal.  Disclosures about Fair Value of Financial Instruments The following methods and assumptions were used to estimate the fair values of the Corporation’s financial instruments as of December 31, 2016 and 2015 .  Cash and Cash Equivalents The carrying amount is a reasonable estimate of fair value.  Securities Available for Sale The fair value of securities available for sale is determined in accordance with the methods described under FASB ASC Topic 820 as described above.  Restricted Investment in Bank Stocks The carrying amount of restricted investment in bank stocks is a reasonable estimate of fair value. The Corporation is required to maintain minimum investment balances in these stocks . These stocks are not actively traded and, therefore, have no readily determinable market value.  Loans Held for Sale The fair value of loans held for sale is determined, when possible, using quoted secondary-market prices. If no such quoted prices exist, the fair value of a loan is determined using quoted prices for a similar loan or loans, adjusted for the specific attributes of that loan.  Loans, net The fair value of loans, excluding all impaired loans, is estimated using discounted cash flow analyses using the current interest rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities. Loans were first segregated by type such as commercial, real estate, and consumer, and were then further segmented into fixed and variable rate. Projected future cash flows are calculated based upon contractual maturity or call dates. For variable rate loans that reprice frequently and have no significant change in credit risk, fair value is based on carrying value.  Interest Receivable The carrying value of interest receivable is a reasonable estimate of fair value. Deposits The fair value of demand deposits, savings accounts and money market deposits is the amount payable on demand at the reporting date. The fair values of time deposits are estimated using a discounted cash flow analyses. The discount rates used are based on rates currently offered for deposits with similar remaining maturities. The fair values of variable rate time deposits that reprice frequently are based on carrying value. The fair values of time deposit liabilities do not take into consideration the value of the Corporation’s long-term relationships with depositors, which may have significant value.  Short-term Borrowings For theses short-term instruments, the carrying amount is a reasonable estimate of fair value.  Long-term Debt Long-term debt includes FHLBP advances (Level 2) and junior subordinated debt (Level 3). The fair value of FHLBP advances are estimated using discounted cash flow analysis, based on quoted prices for new FHLBP advances with similar credit risk characteristics, terms and remaining maturity. These prices are obtained from this active market and represent a market value that is deemed to represent the transfer price if the liability were assumed by a third party. The fair value of junior subordinated debt is estimated using discounted cash flow analysis, based on market rates and spread characteristics of similar debt with similar credit risk characteristics, terms and remaining maturity.  Interest Payable The carrying value of interest payable is a reasonable estimate of fair value.

Assets And Liabilities Subject To Offsetting	 Note 17—Assets and Liabilities Subject to Offsetting  Securities Sold Under Agreements to Repurchase PeoplesBank enters into agreements with c lient s in which it sells securities subject to an obligation to repurchase the same securities (“repurchase agreements”). The contractual maturity of the repurchase agreement is overnight and continues until either party terminates the agreement. These repurchase agreements are accounted for as a collateralized financing arrangement (i.e., secured borrowings) and not as a sale and subsequent repurchase of securities. The obligation to repurchase the securities is reflected as a liability (short-term borrowings) in the Corporation’s consolidated financial statements of condition, while the securities underlying the repurchase agreements are appropriately segregated for safekeeping purposes and remain in the respective securities asset accounts. Thus, there is no offsetting or netting of the securities with the repurchase agreement liabilities.

Merger With Madison Bancorp, Inc. [Abstract]
Merger With Madison Bancorp, Inc.	 Note 20-Merger With Madison Bancorp, Inc.  On July 22, 2014 , the Corporation entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Madison Bancorp, Inc., a Maryland corporation (“Madison”), and CVLY Corp., a Pennsylvania corporation and wholly-owned subsidiary of the Corporation (“Acquisition Subsidiary”). Pursuant to the Merger Agreement, Madison agreed to cause its wholly-owned subsidiary, Madison Square Federal Savings Bank (“MSFSB”), to merge with and into the Corporation’s wholly-owned bank subsidiary, PeoplesBank, with PeoplesBank being the surviving bank in the Bank Merger.  The acquisition of Madison and MSFSB was completed on January 16, 2015 , as reported on a Form 8-K filed on the same date. Pursuant to the Merger Agreement, each share of Madison common stock was converted into the right to receive $22.90 in cash, without interest, and each outstanding option to purchase Madison common stock was converted into the right to receive cash based on a formula set forth in the Merger Agreement. Total consideration paid was $14,425,000 , which included the purchase of 608,116 shares of Madison common stock as well as the cash out of 41,270 options to purchase Madison common stock with an average exercise price of $10.81 per share. The merger was accounted for using acquisition accounting, which requires the Corporation to allocate total consideration transferred to the assets acquired and liabilities assumed, based on their respective fair value at the merger date, with any remaining excess consideration being recorded as goodwill. The table below presents the detail of the total acquisition cost as well as a summary of the assets acquired and liabilities assumed recorded at their estimated fair value, as of the January 16, 2015 acquisition date.      (in thousands, except per share data) January 16, 2015  Cash paid for outstanding shares of Madison common stock and outstanding options $ 14,425   Assets Acquired:  Cash and due from banks $ 35,516  Securities, available for sale 1,396  Loans 77,228  Premises and equipment 2,601  Other assets 17,567  Total assets acquired 134,308  Liabilities Assumed:  Deposits 120,545  Other liabilities 1,639  Total liabilities assumed 122,184   Net goodwill resulting from merger $ 2,301  The fair value of total assets acquired as a result of the merger totaled $134,308,000 , which included $1,396,000 of securities which were subsequently sold in the first quarter of 2015. Additionally, other assets of $17,567,000 included $15,256,000 of receivables related to investment securities sold prior to the merger, pending receipt of sales proceeds, which were subsequently collected. The transaction also resulted in a core deposit intangible of $39,000 and goodwill of $2,301,000 . Goodwill arising from the acquisition consists largely of synergies and the cost savings expected to result from the combining of operations and is not expected to be deductible for income tax purposes.  The following table presents unaudited pro forma information as if the merger between PeoplesBank and MSFSB had been completed on January 1, 2014. The pro forma information does not necessarily reflect the results of operations that would have occurred had MSFSB merged with PeoplesBank at the beginning of 2014. The pro forma financial information does not include the impact of possible business model changes, nor does it consider any potential impacts of current market conditions or revenues, cost savings, or other factors.

Summary Of Significant Accounting Policies [Abstract]
Nature of Operations and Basis of Presentation	Nature of Operations and Basis of Presentation Codorus Valley Bancorp, Inc. (“Corporation” or “Codorus Valley”) is a one-bank holding company headquartered in York, Pennsylvania that provides a full range of banking services through its subsidiary, PeoplesBank, A Codorus Valley Company (“PeoplesBank” or “Bank”). PeoplesBank operates three wholly-owned subsidiaries as of December 31, 2016. The subsidiaries consist of Codorus Valley Financial Advisors, Inc. d/b/a PeoplesWealth Advisors, which sells non-deposit investment products in Pennsylvania, SYC Settlement Services, Inc., which provides real estate settlement services, and Codorus Valley Financial Advisors, Inc. d/b/a PeoplesWealth Advisors, a subsidiary that sells non-deposit investment products in Maryland. In addition, PeoplesBank may periodically create nonbank subsidiaries for the purpose of temporarily holding foreclosed properties pending the liquidation of these properties. PeoplesBank operates under a state charter and is subject to regulation by the Pennsylvania Department of Banking and Securities, and the Federal Deposit Insurance Corporation. The Corporation is subject to regulation by the Federal Reserve Board and the Pennsylvania Department of Banking and Securities.  The consolidated financial statements include the accounts of Codorus Valley and its wholly-owned bank subsidiary, PeoplesBank, and two wholly-owned nonbank subsidiaries, SYC Realty Company, Inc. and CVLY Subsidiary Corp. SYC Realty was inactive during the reportable period of 2016. CVLY Subsidiary Corp. was the surviving merged entity resulting from the acquisition of Madison Bancorp, Inc. (“Madison”) and may be used, as needed, for the financial and legal management of future acquisition transactions. The accounts of CVB Statutory Trust No. 1 and No. 2 are not included in the consolidated financial statements as discussed in Note 8 – Short-term Borrowings and Long-term Debt. All significant intercompany account balances and transactions have been eliminated in consolidation. The accounting and reporting policies of Codorus Valley and subsidiaries conform to accounting principles generally accepted in the United States of America and have been followed on a consistent basis. 
Investment Securities	Investment Securities The classification of securities is determined at the time of acquisition and is reevaluated at each reporting date. Securities classified as available-for-sale are debt securities that the Corporation intends to hold for an indefinite period of time, but not necessarily to maturity. Any decision to sell a security classified as available-for-sale would be based on various factors, including significant movements in interest rates, changes in maturity mix of assets and liabilities, income or liquidity needs, regulatory considerations and other factors. Debt securities available-for-sale are carried at fair value, with unrealized gains and losses, net of taxes, reported as a component of accumulated other comprehensive income in shareholders' equity. Premiums and discounts are recognized in interest income using the interest method over the estimated life of the security. Realized gains and losses from the sale of available-for-sale securities are computed on the basis of specific identification of the adjusted cost of each security and are shown net as a separate line item in the statement of income.  Declines in the fair value of available-for-sale securities below their cost that are deemed to be other-than-temporary are reflected in earnings as realized losses. In estimating other-than-temporary impairment losses, management must first assess whether (a) it has the intent to sell the security and (b) it is more likely than not that it will be required to sell the security prior to its anticipated recovery. These steps are done before assessing whether the cost basis of the investment will be recovered. The assessment of the probability of recovery would consider, among other things, the length of time and the extent to which the fair value has been less than cost and the financial condition and near-term prospects of the issuer. More information about investment securities is provided in Note 3 – Securities. 
Restricted Investment in Bank Stocks	 Restricted Investment in Bank Stocks Restricted stock, which represents required investments in the common stock of correspondent banks, is carried at cost and, as of December 31, 2016 and 2015 consisted primarily of the common stock of the Federal Home Loan Bank of Pittsburgh (FHLBP) and, to a lesser degree, Atlantic Community Bancshares, Inc. (ACBI), the parent company of Atlantic Community Bankers Bank (ACBB). Under the FHLBP’s Capital Plan, PeoplesBank is required to maintain a minimum member stock investment, both as a condition of becoming and remaining a member and as a condition of obtaining borrowings from the FHLBP. The FHLBP uses a formula to determine the minimum stock investment, which is based on the volume of loans outstanding, unused borrowing capacity and other factors. The FHLBP paid dividends during the years ended December 31, 2016 and 2015 . The FHLBP restricts the repurchase of the excess capital stock of member banks. The amount of excess capital stock that can be repurchased from any member is currently the lesser of five percent of the member’s total capital stock outstanding or its excess capital stock outstanding.  Management evaluates the restricted stock for impairment in accordance with FASB ASC Topic 942. Management’s determination of whether these investments are impaired is based on their assessment of the ultimate recoverability of their cost rather than by recognizing temporary declines in value. Using the FHLBP as an example, the determination of whether a decline affects the ultimate recoverability of cost is influenced by criteria such as: (1) the significance of the decline in net assets of the FHLBP as compared to the capital stock amount for the FHLBP and the length of time this situation has persisted; (2) commitments by the FHLBP to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLBP; and (3) the impact of legislative and regulatory changes on institutions and, accordingly, on the customer base of the FHLBP. Management believes no impairment charge was necessary related to the restricted stock during the periods ended December 31, 2016 and 2015 .
Loans Held for Sale	Loans Held for Sale Loans held for sale are primarily comprised of residential mortgage loans originated by the Bank. During 2016, PeoplesBank began originating loans partially guaranteed by the Small Business Administration with the intent to sell the guaranteed portion of secondary-market qualified loans. Loans held for sale are reported at the lower of cost or fair value, as determined by the aggregate commitments from investors or current investor yield requirements. The amount by which cost exceeds fair value, if any, is accounted for as a valuation allowance and is charged to expense in the period of the change. Gains or losses recognized on the sale of mortgage loans and loans guaranteed by the Small Business Administration loans are recognized based on the difference between the selling price and the carrying value of the related loan and are recorded in noninterest income.
Loans	Loans Loans receivable that management has the intent and ability to hold for the foreseeable future or until maturity or payoff, are stated at their outstanding unpaid principal balances less amounts charged off, net of an allowance for loan losses and any deferred fees or costs. Interest income is accrued on the unpaid principal balance. Generally, loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the yield (interest income) over the contractual life of the loan. The loans receivable portfolio is segmented into commercial and consumer loans. Commercial loans consist of the following industry classes: builder & developer, commercial real estate investor, residential real estate investor, hotel/motel, wholesale & retail, agriculture, manufacturing and all other. Consumer loans consist of the following classes: residential mortgage, home equity and all other.  For all classes of loans receivable, the accrual of interest is discontinued when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about further collectability of principal or interest, even though the loan is currently performing. A loan may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. When a loan is placed on nonaccrual status, unpaid interest credited to income in the current year is reversed and unpaid interest accrued in prior years is charged against the allowance for loan losses. Interest received on nonaccrual loans, including impaired loans, generally is either applied against principal or reported as interest income, according to the Corporation’s judgment as to the collectability of principal. Generally, loans are restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time, generally six months, and the ultimate collectability of the total contractual principal and interest is no longer in doubt. The past due status of all classes of loans receivable is determined based on contractual due dates for loan payments.
Acquired Loans	Acquired Loans Acquired loans are initially recorded at their acquisition date fair values. The carryover of allowance for loan losses is prohibited as any credit losses in the loans are included in the determination of the fair value of the loans at the acquisition date. Fair values for acquired loans are based on a discounted cash flow methodology that involves assumptions and judgments as to credit risk, prepayment risk, liquidity risk, default rates, loss severity, payment speeds, collateral values and discount rate.  For acquired loans that are not deemed impaired at acquisition, credit discounts representing principal losses expected over the life of the loan are a component of the initial fair value and amortized over the life of the asset. Subsequent to the acquisition date, the methods used to estimate the required allowance for loan losses on these loans is similar to originated loans. However, the Corporation records a provision for loan losses only when the required allowance for loan losses exceeds any remaining credit discount. The remaining differences between the acquisition date fair value and the unpaid principal balance at the date of acquisition are recorded in interest income over the life of the loan.  Acquired loans that have evidence of deterioration in credit quality since origination and for which it is probable, at acquisition, that the Corporation will be unable to collect all contractually required payments are accounted for as impaired loans under ASC 310-30. The excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable discount and is recognized into interest income over the remaining life of the loans. The difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is referred to as the non-accretable discount. The non-accretable discount represents estimated future credit losses expected to be incurred over the life of the loan. Subsequent decreases to the expected cash flows require the Corporation to evaluate the need for an allowance for loan losses on these loans. Subsequent improvements in expected cash flows result in the reversal of a corresponding amount of the non-accretable discount which the Corporation then reclassifies as an accretable discount that is recognized into interest income over the remaining life of the loans using the interest method.  The following is a summary of acquired impaired loans from the merger, as discussed in Note 20-Merger With Madison Bancorp, Inc.:     (dollars in thousands) January 16, 2015  Contractually required principal and interest at acquisition $ 1,961  Contractual cash flows not expected to be collected 1,185  Expected cash flows at acquisition 776  Interest component of expected cash flows 160  Basis in acquired loans at acquisition - estimated fair value $ 616 
Allowance for Loan Losses	Allowance for Loan Losses The allowance for loan losses represents the Corporation’s estimate of losses inherent in the loan portfolio as of the balance sheet date and is recorded as a reduction to loans. The allowance for loan losses is increased by the provision for loan losses, and decreased by charge-offs, net of recoveries. Loans deemed to be uncollectable are charged against the allowance for loan losses, and subsequent recoveries, if any, are credited to the allowance. All, or part, of the principal balance of loans receivable are charged off to the allowance as soon as it is determined that the repayment of all, or part, of the principal balance is highly unlikely. While the Corporation attributes a portion of the allowance to individual loans and groups of loans that it evaluates and determines to be impaired, the allowance is available to cover all charge-offs that arise from the loan portfolio.  The allowance for loan losses is maintained at a level considered adequate to provide for losses that can be reasonably anticipated. The Corporation performs a quarterly evaluation of the adequacy of the allowance. The allowance is based on the Corporation’s past loan loss experience, known and inherent risks in the portfolio, adverse situations that may affect the borrower’s ability to repay, the estimated value of any underlying collateral, composition of the loan portfolio, current economic conditions and other relevant factors. This evaluation is inherently subjective as it requires material estimates that may be susceptible to significant revision as more information becomes available. The allowance consists of specific, general and unallocated components. The specific component relates to loans that are classified as impaired, generally substandard and nonaccrual loans. For loans that are classified as impaired, an allowance is established when the collateral value (or discounted cash flows or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers pools of loans by loan class including commercial loans not considered impaired, as well as smaller balance homogeneous loans, such as residential real estate, home equity and other consumer loans. These pools of loans are evaluated for loss exposure based upon historical loss rates for each of these classes of loans, adjusted for qualitative (environmental) risk factors. Historical loss rates are based on a two year rolling average of net charge-offs. Qualitative risk factors that supplement historical losses in the evaluation of loan pools are shown below. Each factor is assigned a value to reflect improving, stable or declining conditions based on the Corporation’s best judgment using relevant information available at the time of the evaluation.  ·  Changes in national and local economies and business conditions ·  Changes in the value of collateral for collateral dependent loans  ·  Changes in the level of concentrations of credit ·  Changes in the volume and severity of classified and past due loans ·  Changes in the nature and volume of the portfolio ·  Changes in collection, charge-off, and recovery procedures ·  Changes in underwriting standards and loan terms ·  Changes in the quality of the loan review system ·  Changes in the experience/ability of lending management and key lending staff ·  Regulatory and legal regulations that could affect the level of credit losses ·  Other pertinent environmental factors  The unallocated component is maintained to cover uncertainties that could affect the Corporation’s estimate of probable losses. For example, increasing credit risks and uncertainties, not yet reflected in current leading indicators, associated with prolonged low economic growth, or recessionary business conditions for certain industries or the broad economy, or the erosion of real estate values, represent risk factors, the occurrence of any or all of which can adversely affect a borrowers’ ability to service their loans. The unallocated component of the allowance also reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the loan portfolio, including the unpredictable timing and amounts of charge-offs and related historical loss averages, and specific-credit or broader portfolio future cash flow value and collateral valuation uncertainties which could negatively impact unimpaired portfolio loss factors.  As disclosed in Note 4-Loans, the Corporation engages in commercial and consumer lending. Loans are made within the Corporation’s primary market area and surrounding areas, and include the purchase of whole loan or participation interests in loans from other financial institutions. Commercial loans, which pose the greatest risk of loss to the Corporation, whether originated or purchased, are generally secured by real estate. Within the broad commercial loan segment, the builder & developer and commercial real estate investor loan classes generally present a higher level of risk than other commercial loan classifications. This greater risk is due to several factors, including the concentration of principal in a limited number of loans and borrowers, the effect of general economic conditions on income producing properties, unstable real estate prices and the dependency upon successful construction and sale or operation of the real estate project. Within the consumer loan segment, junior (i.e., second) liens present a slightly higher risk to the Corporation because economic and housing market conditions can adversely affect the underlying value of the collateral and the ability of some borrowers to service their debt.  A loan is considered impaired when, based on current information and events, it is probable that the Corporation will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered in determining impairment include payment status and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. The Corporation determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. Loans that are deemed impaired are evaluated for impairment loss based on the net realizable value of the collateral, as applicable. Loans that are not collateral dependent will rely on the present value of expected future cash flows discounted at the loan’s effective interest rate to determine impairment loss. Large groups of smaller balance homogeneous loans such as residential mortgage loans, home equity loans and other consumer loans are collectively evaluated for impairment, unless they are classified as impaired.  An allowance for loan losses is established for an impaired commercial loan if its carrying value exceeds its estimated fair value. For commercial loans secured by real estate, estimated fair values are determined primarily through third-party appraisals of the underlying collateral. When a real estate secured loan becomes impaired, a decision is made regarding whether an updated certified appraisal of the real estate is necessary. This decision is based on various considerations, including the age of the most recent appraisal, the loan-to-value ratio based on the most recent appraisal and the condition of the property. Appraisals are generally discounted to provide for selling costs and other factors to determine an estimate of the net realizable value of the property. For commercial loans secured by non-real estate collateral, such as accounts receivable, inventory and equipment, estimated fair values are determined based on the borrower’s financial statements, inventory reports, accounts receivable aging or equipment appraisals or invoices. Indications of value from these sources are generally discounted based on the age of the financial information or the quality of the assets. In instances when specific consumer related loans become impaired, they may be partially or fully charged off, which obviates the need for a specific allowance.  Loans whose terms are modified are classified as troubled debt restructurings if the Corporation grants borrowers experiencing financial difficulties concessions that it would not otherwise consider. Concessions granted under a troubled debt restructuring may involve an interest rate that is below the market rate given the associated credit risk of the loan or an extension of a loan’s stated maturity date. Loans classified as troubled debt restructurings are designated as impaired. Non-accrual troubled debt restructurings are restored to accrual status if principal and interest payments, under the modified terms, are current for a reasonable period of time, generally six consecutive months after modification and future payments are reasonably assured. Banking regulatory agencies, as an integral part of their examination process, periodically review the Corporation’s allowance for loan losses and may require the Corporation to recognize additions to the allowance based on their judgments about information available to them at the time of their examination, which may not be currently available to the Corporation. Based on a comprehensive analysis of the loan portfolio, the Corporation believes that the level of the allowance for loan losses at December 31, 2016 is adequate.
Transfers of Financial Assets	Transfers of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Corporation, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Corporation does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Premises and Equipment	Premises and Equipment Land is carried at cost. Premises and equipment are carried at cost less accumulated depreciation. Depreciation expense is calculated principally on the straight-line method over the assets’ estimated useful lives. Estimated useful lives are five to forty years for buildings and improvements, five to twenty years for furniture and equipment and two to seven years for computer equipment and software. Maintenance and repairs are charged to expense as incurred. The cost of significant improvements to existing assets is capitalized and amortized over the shorter of the asset’s useful life or related lease term. When facilities are retired or otherwise disposed of, the depreciated cost is removed from the asset accounts, and any gain or loss is reflected in the statement of income.
Foreclosed Real Estate	Foreclosed Real Estate Foreclosed real estate, included in other assets, is comprised of property acquired through a foreclosure proceeding or property that is acquired through in substance foreclosure. Foreclosed real estate is initially recorded at fair value minus estimated costs to sell at the date of foreclosure, establishing a new cost basis. Any difference between the carrying value and the new cost basis is charged against the allowance for loan losses. Appraisals, obtained from an independent third party, are generally used to determine fair value. After foreclosure, management reviews valuations at least quarterly and adjusts the asset to the lower of cost or fair value minus estimated costs to sell through a valuation allowance or a charge-off. Costs related to the improvement of foreclosed real estate are generally capitalized until the real estate reaches a saleable condition subject to fair value limitations. Revenue and expense from operations and changes in the valuation allowance are included in noninterest expense. When a foreclosed real estate asset is ultimately sold, any gain or loss on the sale is included in the income statement as a component of noninterest expense. At December 31, 2016 , foreclosed real estate, net of allowance, was $2,705,000 , compared to $2,913,000 for December 31, 2015 . Included within loans receivable as of December 31, 2016, was a recorded investment of $230,000 of consumer mortgage loans secured by residential real estate properties, for which formal foreclosure proceedings were in process according to local requirements of the applicable jurisdiction. 
Investments In Real Estate Partnerships	Investments in Real Estate Partnerships In March 2003, PeoplesBank acquired a 73.47 percent limited partner interest in a real estate joint venture known as Village Court, which was formed to develop, construct, own and operate a 60 -unit affordable housing complex located in Dover Township, York County, Pennsylvania. Construction of the housing complex was completed in the fourth quarter of 2004 and the complex was fully leased by December 31, 2004. The investment balance included in other assets has been fully amortized as of December 31, 2016 and 2015 .  Investment and related tax credits are accounted for under the effective yield method of accounting under which tax credits are recognized as they are allocated, and the cost of the investment is amortized to provide a constant yield over the period that tax credits are allocated, generally ten years.
Bank Owned Life Insurance	Bank Owned Life Insurance PeoplesBank invests in bank owned life insurance (BOLI) as a source of funding for employee benefit expenses. BOLI involves the purchasing of life insurance by PeoplesBank on a select group of employees and directors. PeoplesBank is the owner and beneficiary of the policies. This life insurance investment is carried at the cash surrender value of the underlying policies and is included in other assets in the amount of $31,621,000 at December 31, 2016 , compared to $23,980,000 at December 31, 2015 .
Mortgage Servicing Rights	Mortgage Servicing Rights PeoplesBank retained servicing of sold mortgage loans beginning in 2016. The mortgage servicing rights (MSRs) associated with the sold loans are included in other assets on the consolidated balance sheets at an amount equal to the estimated fair value of the contractual rights to service the mortgage loans. The MSR asset is amortized as a reduction to servicing income. The MSR asset is evaluated periodically for impairment and carried at the lower of amortized cost or fair value. A third party calculates fair value by discounting the estimated cash flows from servicing income using a rate consistent with the risk associated with these assets and an expected life commensurate with the expected life of the underlying loans. In the event that the amortized cost of the MSR asset exceeds the fair value of the asset, a valuation allowance would be established through a charge against servicing income. Subsequent fair value evaluations may determine that impairment has been reduced or eliminated, in which case the valuation allowance would be reduced through a credit to earnings. At December 31, 2016, the MSR asset was $324,000 and the balance of residential mortgage loans serviced for third parties was $36,969,000 . As December 31, 2015, there were no MSR assets.
Trust and Investment Services Assets	Trust and Investment Services Assets Assets held by PeoplesBank in a fiduciary or agency capacity for its clients are not included in the consolidated balance sheets since these items are not assets of PeoplesBank.
Advertising	Advertising Advertising costs are charged to expense when incurred.
Income Taxes	Income Taxes Deferred income taxes are provided on the liability method whereby deferred tax assets are recognized for deductible temporary differences and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax basis. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted through the provision for income taxes for the effects of changes in tax laws and rates on the effective date.  The Corporation accounts for uncertain tax positions as required by FASB ASC Topic 740. FASB ASC Topic 740 clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements. Specifically, the accounting standard prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return as well as guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. No significant income tax uncertainties have been identified by the Corporation; therefore, the Corporation recognized no adjustment for unrecognized income tax benefits for the years ended December 31, 2016 and 2015. The Corporation’s policy is to recognize interest and penalties on unrecognized tax benefits in income taxes expense in the Consolidated Statement of Income. The Corporation did no t recognize any interest and penalties for the years ended December 31, 2016 , 2015 and 2014 . The tax years subject to examination by the taxing authorities are the years ended December 31, 2015 , 2014 , and 2013 .
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America 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. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the evaluation of other-than-temporary impairment losses for investment securities and the evaluation of impairment losses for foreclosed real estate.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in Note 16 – Fair Value Measurements and Fair Values of Financial Instruments. Fair value estimates involve uncertainties and matters of significant judgment. Changes in assumptions or in market conditions could significantly affect the estimates.
Goodwill and Core Deposit Intangible Assets	Goodwill and Core Deposit Intangible Assets Goodwill arising from acquisitions is not amortized, but is subject to an annual impairment test. This test consists of a qualitative analysis. If the Corporation determines events or circumstances indicate that it is more likely than not that goodwill is impaired, a quantitative analysis must be completed. Analyses may also be performed between annual tests. Significant judgment is applied when goodwill is assessed for impairment. This judgment includes developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables, incorporating general economic and market conditions, and selecting an appropriate control premium. The Corporation completes its annual goodwill impairment test on October 1 st of each year. Based upon the analysis, the Corporation concluded that the amount of recorded goodwill was not impaired as of October 1, 2016.  Core deposit intangibles represent the value assigned to demand, interest checking, money market, and savings accounts acquired as part of an acquisition. The core deposit intangible value represents the future economic benefit of potential cost savings from acquiring core deposits as part of an acquisition compared to the cost of alternative funding sources and the alternative cost to grow a similar core deposit base. The core deposit intangible asset resulting from the merger with Madison Bancorp, Inc. was determined to have a definite life and is being amortized using the sum of the years’ digits method over ten years. All intangible assets must be evaluated for impairment if certain events or changes in circumstances occur. Any impairment write-downs would be recognized as expense on the consolidated statements of income.  At December 31, 2016, the Corporation does not have any indicators of potential impairment of either goodwill or core deposit intangibles.
Per Common Share Data	Per Common Share Data Basic net income per common share is calculated as net income available to common shareholders divided by the weighted average number of common shares outstanding. Diluted net income per common share is calculated as net income available to common shareholders divided by the weighted average number of common shares outstanding plus common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. Potential common shares that may be issued by the Corporation relate solely to outstanding stock options and are determined using the treasury stock method. All share and per share amounts are adjusted for stock dividends that are declared prior to the issuance of the consolidated financial statements.  The computation of net income per common share for the years ended December 31, 2016 , 2015 and 2014 is provided in the table below.     (in thousands, except per share data) 2016 2015 2014  Net income available to common shareholders $ 13,086 $ 11,015 $ 11,595   Weighted average shares outstanding (basic) 8,375 6,555 6,187  Effect of dilutive stock options 71 71 108  Weighted average shares outstanding (diluted) 8,446 6,626 6,295   Basic earnings per common share $ 1.56 $ 1.68 $ 1.88  Diluted earnings per common share $ 1.55 $ 1.67 $ 1.84   Anti-dilutive stock options excluded from the computation of earnings per share 78 112 62 
Stock-Based Compensation	Stock-Based Compensation The Corporation accounts for its stock-based compensation awards in accordance with FASB ASC Topic 718, which requires public companies to recognize compensation expense, related to stock-based compensation awards in their statements of operations. Compensation expense is equal to the fair value of the stock-based compensation awards on the grant date and is recognized over the vesting period of such awards. More information is provided in Note 12 – Stock-Based Compensation.
Cash Flow Information	 Cash Flow Information For purposes of the statements of cash flows, the Corporation considers interest bearing deposits with banks, cash and due from banks, and federal funds sold to be cash and cash equivalents.  Supplemental cash flow information is provided in the table below.     Years ended December 31,  (dollars in thousands) 2016 2015 2014  Cash paid during the period for:  Income taxes $ 4,973 $ 6,050 $ 3,511  Interest $ 8,667 $ 8,183 $ 7,954   Noncash investing activities:  Transfer of loans to foreclosed real estate $ 318 $ 41 $ 1,597  Charitable donation of foreclosed real estate $ 0 $ 0 $ 43 
Off-Balance Sheet Financial Instruments	Off-Balance Sheet Financial Instruments In the ordinary course of business, the Corporation enters into off-balance sheet financial instruments consisting of commitments to extend credit and standby letters of credit. These financial instruments are recorded on the balance sheet when they become a receivable to the Corporation.
Comprehensive Income and Accumulated Other Comprehensive Income	Comprehensive Income and Accumulated Other Comprehensive Income Accounting principles generally accepted in the United States of America require that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities, such as unrealized gains and losses on available-for-sale securities, are reported as a separate component of the shareholders’ equity section of the balance sheet, such items, along with net income, are components of comprehensive income.
Segment Reporting	Segment Reporting Management has determined that it operates in only one segment, community banking. The Corporation’s non-banking activities are insignificant to the consolidated financial statements.
Recent Accounting Pronouncements	Recent Accounting Pronouncements  Pronouncements Adopted in 2016  In March 2016, the FASB issued ASU 2016-09, Compensation – Stock Compensation (Topic 718). This standard introduces amendments intended to simplify the accounting for stock compensation. Specifically, the ASU requires all excess tax benefits and tax deficiencies (including tax benefits of dividends on share-based payment awards) to be recognized as income tax expense or benefit in the income statement. In the fourth quarter of 2016, the Corporation elected early adoption of ASU 2016-09, effective January 1, 2016, and has applied the ASU using a modified retrospective approach. Adoption of this standard had the following impact on the Corporation’s consolidated financial statements: · Excess tax benefits are recognized in the provision for income tax expense rather than additional paid in capital. An income tax benefit of approximately $134,000 was recognized for the year ended December 31, 2016 as a result of the adoption of ASU 2016-09. · Excess tax benefits are presented as operating activities rather than as an inflow from financing activities and an outflow from operating activities in the consolidated statement of cash flows. The Corporation’s early adoption of ASU 2016-09 resulted in the prospective presentation of $134,000 of excess tax benefits included in the change in other liabilities in the consolidated statement of cash flows for the year ended December 31, 2016. No prior periods have been adjusted. · The Corporation has elected to continue the current process of recognizing forfeitures as a reversal of compensation expense in the period in which the forfeiture occurs.  Pronouncements Not Yet Effective  In January 2017, the FASB issued ASU 2017-04, Intangibles – Goodwill and Other (Topic 350). This standard simplifies the test for goodwill impairment by eliminating the requirement to calculate the implied fair value of goodwill, which currently is Step 2 of the goodwill impairment test. Instead, the goodwill impairment test will consist of a single quantitative step comparing the fair value of the reporting unit with its carrying amount. An entity should recognize a goodwill impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. The new standard is effective for annual and any interim goodwill impairment tests in reporting periods beginning after December 15, 2019. Early adoption is permitted. The Corporation intends to adopt this standard effective with its October 1, 2020 goodwill impairment test and the adoption of this standard is not expected to have a material impact on the its consolidated financial statements.  In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments. This standard clarifies how certain cash receipts and cash payments are presented and classified in the statement of cash flows to reduce diversity in practice. This standard contains guidance clarifying when an entity should separate cash receipts and cash payments and classify them into more than one class of cash flows (including when reasonable judgment is required to estimate and allocate cash flows) versus when an entity should classify the aggregate amount into one class of cash flows on the basis of predominance. The new standard is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. The Corporation intends to adopt this standard effective with its March 31, 2018 quarterly report on Form 10-Q and does not expect the adoption of the ASU to have a material impact on its consolidated financial statements.   In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326). This standard adds a new Topic 326 which requires companies to measure and record impairment on financial instruments at the time of origination using the expected credit loss (CECL) model. The CECL model calculates impairment based on historical experience, current conditions, and reasonable and supportable forecasts, and reflects the organization’s current estimate of all expected credit losses over the contractual term of its financial assets. The new standard is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018. The Corporation is currently evaluating the impact of the adoption of this guidance on its consolidated financial statements and is in the initial stages of assessing and gathering the necessary data to implement the new standard.  In February 2016, the FASB issued ASU 2016-02, Leases. From the lessee's perspective, the new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement for a lessees. From the lessor's perspective, the new standard requires a lessor to classify leases as either sales-type, finance or operating. A lease will be treated as a sale if it transfers all of the risks and rewards, as well as control of the underlying asset, to the lessee. If risks and rewards are conveyed without the transfer of control, the lease is treated as a financing lease. If the lessor doesn’t convey risks and rewards or control, an operating lease results. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. A modified retrospective transition approach is required for lessors for sales-type, direct financing, and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Corporation is currently evaluating the impact of the adoption of this guidance on its consolidated financial statements and has determined that the provisions of ASU 2016-02 will result in an increase in assets to recognize the present value of the lease obligations (right-of-use assets) with a corresponding increase in liabilities. The initial measurement of the right-of-use asset and the corresponding liability will be affected by certain key assumptions such as expectations of renewals or extensions and the interest rate to be used to discount the future lease obligations. The Corporation is currently assessing its lease portfolio to determine the key assumptions; however, the total impact of the new standard will be affected by any new leases that are executed, leases that are terminated prior to the effective date, and any leases with changes to key assumptions or expectations such as renewals and extensions, and discount rates. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). This standards update provides a framework that replaces most existing revenue recognition guidance. The guidance requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In December 2016, the FASB issued ASU 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers. This ASU amends the new revenue standard to make minor technical corrections that affect narrow aspects of the guidance, including contract cost accounting, disclosures, and other matters. ASU 2014-09 and ASU 2016-20 are effective for interim and annual reporting periods beginning after December 15, 2017. Early adoption is not permitted. The Corporation is evaluating the anticipated effects of these ASUs on its consolidated financial statements and related disclosures. The Corporation has determined that certain noninterest income financial statement line items, including trust and investment services fees, income from mutual fund, annuity and insurance sales, service charges on deposit accounts, and other noninterest income, contain revenue streams that are in scope of these updates. Preliminary findings indicate that there may be some changes in the presentation of certain revenues and expenses based on the principal versus agent guidance within these updates.
