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 The accompanying consolidated balance sheet at December 31, 2017 has been derived from audited financial statements, and the unaudited interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information, the instructions to Form 10-Q, and FASB Accounting Standards Codification (ASC) 270. Accordingly, the interim financial statements do not include all of the financial information and notes required by generally accepted accounting principles for complete financial statements. In the opinion of management, the interim consolidated financial statements include all adjustments necessary to present fairly the financial condition and results of operations for the reported periods, and all such adjustments are of a normal and recurring nature.  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 March 31, 2018 . Codorus Valley Financial Advisors, Inc. d/b/a PeoplesWealth Advisors, which sells nondeposit 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, which sells nondeposit 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 a wholly-owned nonbank subsidiary, SYC Realty Company, Inc. SYC Realty was inactive during the period ended March 31, 2018 . The accounts of CVB Statutory Trust No. 1 and No. 2 are not included in the consolidated financial statements as discussed in Note 7—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.  These consolidated statements should be read in con j unction with the notes to the audited consolidated financial statements contained in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2017 .  The results of operations for the three months ended March 31, 2018 are not necessarily indicative of the results to be expected for the full year.  In accordance with FASB ASC 855, the Corporation evaluated the events and transactions that occurred after the balance sheet date of March 31, 2018 and through the date these consolidated financial statements were issued, for items of potential recognition or disclosure.  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. Generally, 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 may be currently performing. A past due loan may remain on accrual status if it is in the process of collection and 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, nonaccrual 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 FASB 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. 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 by management to be 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 or private equity companies. 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 higher risk to the Corporation because economic and housing market conditions can adversely affect the underlying value of the collateral, which could render the Corporation under-secured or unsecured. In addition, economic and housing market conditions can adversely affect 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 an analysis of the loan portfolio, the Corporation believes that the level of the allowance for loan losses at March 31, 2018 is adequate.  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 write-down. 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 March 31, 2018 , there was $119,000 of foreclosed real estate, which included no residential real estate, compared to $216,000, which included $96,000 of residential real estate, at December 31, 2017 . Included within loans receivable as of March 31, 2018 was a recorded investment of $280,000 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.  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 March 31, 2018, the balance of residential mortgage loans serviced for third parties was $77,087,000 compared to $70,780,000 at December 31, 2017.      Three months ended  March 31,  (dollars in thousands) 2018 2017  Amortized cost:  Balance at beginning of year $ 672 $ 324  Originations of mortgage servicing rights 68 107  Amortization expense (25) (15)  Balance at end of period $ 715 $ 416         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 a qualitative analysis of goodwill, the Corporation concluded that the amount of recorded goodwill was not impaired as of October 1, 2017.  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 March 31, 2018 , the Corporation does not have any indicators of potential impairment of either goodwill or core deposit intangibles.  Revenue from Contracts with Customers Revenue from contracts with customers that are required to be recognized under FASB ASC Topic 606 - Revenue from Contracts with Customers (ASC 606) is measured based on consideration specified in a contract with a customer, and excludes any sales incentives and amounts collected on behalf of third parties. The Corporation recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer.  The majority of the Corporation’s revenue-generating transactions are not within the scope of ASC 606, including revenue generated from financial instruments, such as our loans, letters of credit, derivatives and investment securities, as well as revenue related to our mortgage servicing activities, as these activities are subject to other U.S. Generally Accepted Accounting Principles (GAAP) discussed elsewhere within our disclosures. Descriptions of our revenue-generating activities that are within the scope of ASC 606, which are presented in our consolidated statements of income as components of non-interest income are as follows:  Trust and investment service fees - The Corporation provides trust, investment management custody and irrevocable life insurance trust services to customers. Such services are rendered in accordance with the underlying contracts for which fees are earned. Performance obligations are typically fulfilled on a monthly basis which is when revenue is recognized.  Income from mutual fund, annuity and insurance sales – The Corporation sells mutual funds, annuity and insurance products to its customers. The Corporation’s performance obligation is met upon the signing of the product agreement and, in certain cases, a time component may exist when the customer has the right to rescind the agreement with or without penalty. The Corporation recognizes revenues upon delivery of the product or service unless there is a time component and revenues are recognized utilizing the expected value method.  Service charges on deposits accounts - These represent general service fees for monthly account maintenance and activity- or transaction based fees and consist of transaction-based revenue, time-based revenue (service period), item-based revenue or some other individual attribute-based revenue. Revenue is recognized when the performance obligation is completed which is generally monthly for account maintenance services or when a transaction has been completed.  Per Share Data All per share computations include the effect of stock dividends distributed. The computation of net income per share is provided in the table below.      Three months ended  March 31,  (in thousands, except per share data) 2018 2017  Net income $ 4,083 $ 3,419   Weighted average shares outstanding (basic) 8,913 8,851  Effect of dilutive stock options 92 99  Weighted average shares outstanding (diluted) 9,005 8,950   Basic earnings per share $ 0.46 $ 0.39  Diluted earnings per share $ 0.45 $ 0.38   Anti-dilutive stock options excluded from the  computation of earnings per share 16 0  Comprehensive Income Accounting principles generally accepted in the United States 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.  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.      Three months ended  March 31,  (dollars in thousands) 2018 2017  Cash paid during the period for:  Income taxes $ 0 $ 0  Interest $ 3,298 $ 2,432   Noncash investing activities:  Transfer of loans held for sale to the held-to-maturity portfolio $ 0 $ 228  Sale of foreclosed real estate through loans $ 0 $ 910  Recent Accounting Pronouncements  Pronouncements Adopted in 2018  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. The Corporation adopted this standard effective with its March 31, 2018 quarterly report on Form 10-Q. The adoption of the new standard did not have a material impact on its consolidated financial statements.  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. 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. The Corporation adopted this standard on January 1, 2018 utilizing the modified retrospective method and the adoption of the new standard did not have a material impact on the recognition of revenue .  In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments – Overall (Subtopic 825-10) - Recognition and Measurement of Financial Assets and Financial Liabilities. A SU 2016-01 is intended to improve the recognition and measurement of financial instruments by requiring equity investments to be measured at fair value with changes in fair value recognized in net income; requiring public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; requiring separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements; eliminating the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured and amortized at cost on the balance sheet; and requiring a reporting organization to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the organization has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. ASU 2016-01 is effective for annual periods and interim periods within those annual periods, beginning after December 15, 2017. The amendments should be applied by means of a cumulative effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity securities without readily determinable fair values (including disclosure requirements) should be applied prospectively to equity investments that exist as of the date of adoption. In February 2018, the FASB issued ASU No. 2018-03 which includes technical corrections and improvements to clarify the guidance in ASU No. 2016-01. The Corporation adopted ASU 2016-01 on January 1, 2018 and it did not have a material effect on its accounting for fair value disclosures and other disclosure requirements.   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 rep

Securities [Abstract]
Securities	 Note 2-Securities  A summary of securities available-for-sale at March 31, 2018 and December 31, 2017 is provided below. The securities available-for-sale portfolio is generally comprised of high quality debt instruments, principally 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 March 31, 2018 , 84 percent of the fair value of the municipal bond portfolio was concentrated in the Commonwealth of Pennsylvania.

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 unrealized losses at March 31, 2018 were primarily the result of changes in market interest rates and that the Corporation has the ability to hold these investments for a time necessary to recover the amortized cost. Through March 31, 2018 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.

Restricted Investment In Bank Stocks [Abstract]
Restricted Investment In Bank Stocks	 Note 3—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 March 31, 2018 and December 31, 2017 , 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 member banks, including PeoplesBank, are required to maintain a minimum stock investment. 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 periods ended March 31, 2018 and 2017. 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 a ssessment 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 March 31, 2018 and 2017.

Loans [Abstract]
Loans	 Note 4—Loans  Loan Portfolio Composition  The table below provides the composition of the loan portfolio at March 31, 2018 and December 31, 2017 . 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 “Other” 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.

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 meets at a minimum quarterly, 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. A loan classified “doubtful” has all the weaknesses inherent in one classified substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and value highly improbable and the possibility of loss extremely high. 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. The table below does not include the regulatory classification of “doubtful,” which is subsumed within the nonaccrual risk rating category, nor does it include the regulatory classification of “loss” because the Corporation promptly charges off known loan losses.  The table below presents a summary of loan risk ratings by loan class at March 31, 2018 and December 31, 2017 .

Generally, impaired loans are certain loans risk rated substandard and all loans risk rated nonaccrual or classified as troubled debt restructurings. An allowance is established for individual loans that are commercial related where the Corporation has doubt as to full recovery of the outstanding principal balance.

Concessions granted with respect to these loans generally 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 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 three months ended March 31, 2018 and 2017. There were no defaults during the three ended March 31, 2018 for TDRs entered into during the previous 12 month period.

Short-Term Borrowings And Long-Term Debt [Abstract]
Short-Term Borrowings And Long-Term Debt	 Note 7—Short-Term Borrowings and Long-Term Debt  Short-term borrowings consist of securities sold under agreements to repurchase, federal funds purchased and other borrowings. At March 31, 2018, the balance of securities sold under agreements to repurchase was $9,715,000 compared to $10,295,000 at December 31, 2017. At March 31, 2018, the balance of other short-term borrowings was $15,000,000 compared to $10,200,000 at December 31, 2017. The following table presents a summary of long-term debt as of March 31, 2018 and December 31, 2017. PeoplesBank’s long-term debt obligations to the FHLBP are fixed rate instruments. Under terms of a blanket collateral agreement with the FHLBP, the obligations are secured by FHLBP stock and PeoplesBank qualifying loan receivables, principally real estate secured loans.

The letters of credit took the place of securities pledged to the municipalities for their deposits maintained at PeoplesBank.  In June 2006, Codorus Valley formed CVB Statutory Trust No. 2, a wholly-owned special purpose subsidiary whose sole purpose was to facilitate a pooled trust preferred debt issuance of $7,217,000 . In November 2004, Codorus Valley formed CVB Statutory Trust No. 1 to facilitate a pooled trust preferred debt issuance of $3,093,000 . The Corporation owns all of the common stock of these nonbank subsidiaries, and the debentures are the sole assets of the Trusts. The accounts of both Trusts are not consolidated for financial reporting purposes in accordance with FASB ASC 810. For regulatory capital purposes, all of the Corporation’s trust preferred securities qualified as Tier 1 capital for all reported periods. Trust preferred securities are subject to capital limitations under the FDIC’s risk-based capital guidelines. The Corporation used the net proceeds from these offerings to fund its operations.

Regulatory Matters [Abstract]
Regulatory Matters	 Note 8—Regulatory Matters  The Corporation and PeoplesBank are subject to various regulatory capital requirements. Failure to meet minimum capital requirements can initiate certain mandatory and possible additional discretionary actions by regulators that, if imposed, could have a material adverse 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 classifications 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.  As of March 31, 2018, the Corporation and PeoplesBank met the minimum requirements of the Basel III framework, and PeoplesBank’s capital ratios exceeded the amount to be considered “well capitalized” as defined in the regulations. The table below provides a comparison of the Corporation’s and PeoplesBank’s risk-based capital ratios and leverage ratios to the minimum regulatory requirement for the periods indicated.

Guarantees [Abstract]
Guarantees	Note 11—Guarantees Codorus Valley does not issue any guarantees that would require liability recognition or disclosure, other than its standby letters of credit. Standby letters of credit are written conditional commitments issued by PeoplesBank to guarantee the performance of a client to a third party. Generally, all letters of credit, when issued, have expiration dates within one year. The credit risk involved in issuing letters of credit is essentially the same as those that are involved in extending loan facilities to clients. The Corporation generally holds collateral and/or personal guarantees supporting these commitments. The Corporation had $22,633,000 of standby letters of credit outstanding on March 31, 2018 , compared to $23,603,000 on December 31, 2017 . Management believes that the proceeds obtained through a liquidation of collateral and the enforcement of guarantees would be sufficient to cover the potential amount of future payments required under the corresponding letters of credit. The amount of the liability as of March 31, 2018 and December 31, 2017 , for guarantees under standby letters of credit issued, was not material. Many of the commitments are expected to expire without being drawn upon and, therefore, generally do not present significant liquidity risk to the Corporation or PeoplesBank.

Fair Value of Assets and Liabilities [Abstract]
Fair Value of Assets and Liabilities	 Note 12—Fair Value of Assets and Liabilities  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 March 31, 2018 , the fair value of impaired loans with a valuation allowance or charge-off was $481,000 , net of charge-offs of $501,000 . At December 31, 2017 the fair value of impaired loans with a valuation allowance or charge-off was $1,331,000 , net of valuation allowances of $243,000 and charge-offs of $506,000 .  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 on an independent third-party appraisal of the property or occasionally on a recent sales offer. At March 31, 2018 and December 31, 2017 , there were no foreclosed real estate assets with a valuation allowance or write-down. 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 March 31, 2018 , the fair value of the mortgage servicing rights asset was $ 844,000 . At December 31, 2017 , the fair value of the mortgage servicing rights asset was $769,000 .

(2) Appraisals may be adjusted downward by the Corporation's management for qualitative factors such as economic conditions  and estimated liquidation expenses. 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 value of the Corporation’s financial instruments as of March 31, 2018 and December 31, 2017 : 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, f or March 31, 2018, are estimated on an exit price basis incorporating discounts for such factors as credit, liquidity and marketability factors. This is not comparable with the fair values disclosed for December 31, 2017, which were based on an entrance price basis. For that date, fair values of variable rate loans that reprice frequently and with no significant change in credit risk were based on carrying values. The fair values of other loans as of that date were estimated using discounted cash flow analyses which used interest rates then being offered for loans with similar terms to borrowers of similar credit quality.  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 these 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 is 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.  Off-balance sheet instruments Off-balance sheet instruments consist of lending commitments and letters of credit and are based on fees currently charged in the market to enter into similar arrangements, taking into account the remaining terms of the agreements and counterparties’ credit standing. These amounts were not considered material.  The following presents the carrying amounts and estimated fair values of the Corporation’s financial instruments as of March 31, 2018 and December 31, 2017 .

Assets And Liabilities Subject To Offsetting	Note 13—Assets and Liabilities Subject to Offsetting  Securities Sold Under Agreements to Repurchase  PeoplesBank enters into agreements with clients 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.

Summary Of Significant Accounting Policies [Abstract]
Nature of Operations and Basis of Presentation	Nature of Operations and Basis of Presentation The accompanying consolidated balance sheet at December 31, 2017 has been derived from audited financial statements, and the unaudited interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information, the instructions to Form 10-Q, and FASB Accounting Standards Codification (ASC) 270. Accordingly, the interim financial statements do not include all of the financial information and notes required by generally accepted accounting principles for complete financial statements. In the opinion of management, the interim consolidated financial statements include all adjustments necessary to present fairly the financial condition and results of operations for the reported periods, and all such adjustments are of a normal and recurring nature.  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 March 31, 2018 . Codorus Valley Financial Advisors, Inc. d/b/a PeoplesWealth Advisors, which sells nondeposit 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, which sells nondeposit 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 a wholly-owned nonbank subsidiary, SYC Realty Company, Inc. SYC Realty was inactive during the period ended March 31, 2018 . The accounts of CVB Statutory Trust No. 1 and No. 2 are not included in the consolidated financial statements as discussed in Note 7—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.  These consolidated statements should be read in con j unction with the notes to the audited consolidated financial statements contained in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2017 .  The results of operations for the three months ended March 31, 2018 are not necessarily indicative of the results to be expected for the full year.  In accordance with FASB ASC 855, the Corporation evaluated the events and transactions that occurred after the balance sheet date of March 31, 2018 and through the date these consolidated financial statements were issued, for items of potential recognition or disclosure.
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. Generally, 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 may be currently performing. A past due loan may remain on accrual status if it is in the process of collection and 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, nonaccrual 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 FASB 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.
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 by management to be 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 or private equity companies. 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 higher risk to the Corporation because economic and housing market conditions can adversely affect the underlying value of the collateral, which could render the Corporation under-secured or unsecured. In addition, economic and housing market conditions can adversely affect 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 an analysis of the loan portfolio, the Corporation believes that the level of the allowance for loan losses at March 31, 2018 is adequate.
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 write-down. 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 March 31, 2018 , there was $119,000 of foreclosed real estate, which included no residential real estate, compared to $216,000, which included $96,000 of residential real estate, at December 31, 2017 . Included within loans receivable as of March 31, 2018 was a recorded investment of $280,000 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.
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 March 31, 2018, the balance of residential mortgage loans serviced for third parties was $77,087,000 compared to $70,780,000 at December 31, 2017.      Three months ended  March 31,  (dollars in thousands) 2018 2017  Amortized cost:  Balance at beginning of year $ 672 $ 324  Originations of mortgage servicing rights 68 107  Amortization expense (25) (15)  Balance at end of period $ 715 $ 416       
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 a qualitative analysis of goodwill, the Corporation concluded that the amount of recorded goodwill was not impaired as of October 1, 2017.  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 March 31, 2018 , the Corporation does not have any indicators of potential impairment of either goodwill or core deposit intangibles.
Revenue from Contracts with Customers	Revenue from Contracts with Customers Revenue from contracts with customers that are required to be recognized under FASB ASC Topic 606 - Revenue from Contracts with Customers (ASC 606) is measured based on consideration specified in a contract with a customer, and excludes any sales incentives and amounts collected on behalf of third parties. The Corporation recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer.  The majority of the Corporation’s revenue-generating transactions are not within the scope of ASC 606, including revenue generated from financial instruments, such as our loans, letters of credit, derivatives and investment securities, as well as revenue related to our mortgage servicing activities, as these activities are subject to other U.S. Generally Accepted Accounting Principles (GAAP) discussed elsewhere within our disclosures. Descriptions of our revenue-generating activities that are within the scope of ASC 606, which are presented in our consolidated statements of income as components of non-interest income are as follows:  Trust and investment service fees - The Corporation provides trust, investment management custody and irrevocable life insurance trust services to customers. Such services are rendered in accordance with the underlying contracts for which fees are earned. Performance obligations are typically fulfilled on a monthly basis which is when revenue is recognized.  Income from mutual fund, annuity and insurance sales – The Corporation sells mutual funds, annuity and insurance products to its customers. The Corporation’s performance obligation is met upon the signing of the product agreement and, in certain cases, a time component may exist when the customer has the right to rescind the agreement with or without penalty. The Corporation recognizes revenues upon delivery of the product or service unless there is a time component and revenues are recognized utilizing the expected value method.  Service charges on deposits accounts - These represent general service fees for monthly account maintenance and activity- or transaction based fees and consist of transaction-based revenue, time-based revenue (service period), item-based revenue or some other individual attribute-based revenue. Revenue is recognized when the performance obligation is completed which is generally monthly for account maintenance services or when a transaction has been completed.

Comprehensive Income	Comprehensive Income Accounting principles generally accepted in the United States 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.
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.

Recent Accounting Pronouncements	Recent Accounting Pronouncements  Pronouncements Adopted in 2018  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. The Corporation adopted this standard effective with its March 31, 2018 quarterly report on Form 10-Q. The adoption of the new standard did not have a material impact on its consolidated financial statements.  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. 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. The Corporation adopted this standard on January 1, 2018 utilizing the modified retrospective method and the adoption of the new standard did not have a material impact on the recognition of revenue .  In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments – Overall (Subtopic 825-10) - Recognition and Measurement of Financial Assets and Financial Liabilities. A SU 2016-01 is intended to improve the recognition and measurement of financial instruments by requiring equity investments to be measured at fair value with changes in fair value recognized in net income; requiring public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; requiring separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements; eliminating the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured and amortized at cost on the balance sheet; and requiring a reporting organization to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the organization has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. ASU 2016-01 is effective for annual periods and interim periods within those annual periods, beginning after December 15, 2017. The amendments should be applied by means of a cumulative effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity securities without readily determinable fair values (including disclosure requirements) should be applied prospectively to equity investments that exist as of the date of adoption. In February 2018, the FASB issued ASU No. 2018-03 which includes technical corrections and improvements to clarify the guidance in ASU No. 2016-01. The Corporation adopted ASU 2016-01 on January 1, 2018 and it did not have a material effect on its accounting for fair value disclosures and other disclosure requirements.   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 its consolidated financial statements based on current circumstances.   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 and financial statement impact; 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.
