Summary Of Significant Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	NOTE 1-Summary of Significant Accounting Policies  Nature of Operations and Basis of Presentation Codorus Valley Bancorp, Inc. (“Corporation” or “Codorus Valley”) is a one-bank holding company headquartered in York, Pennsylvania that provides a full range of banking services through its subsidiary, PeoplesBank, A Codorus Valley Company (“PeoplesBank” or “Bank”). PeoplesBank operates two wholly-owned subsidiaries as of December 31, 2019 . The subsidiaries consist of Codorus Valley Financial Advisors, Inc. d/b/a Peoples Wealth Advisors, which sells non-deposit investment products and SYC Settlement Services, Inc., which provides real estate settlement services. 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 reportable period of 2019 . The accounts of CVB Statutory Trust No. 1 and No. 2 are not included in the consolidated financial statements as discussed in Note 8 – Short-term Borrowings and Long-term Debt. All significant intercompany account balances and transactions have been eliminated in consolidation. The accounting and reporting policies of Codorus Valley and subsidiaries conform to accounting principles generally accepted in the United States of America and have been followed on a consistent basis.  Reclassifications Certain amounts in the 2018 and 2017 consolidated financial statements and notes have been reclassified to conform to the 2019 presentation.  Investment Securities The classification of securities is determined at the time of acquisition and is reevaluated at each reporting date. Securities classified as available-for-sale are debt securities that the Corporation intends to hold for an indefinite period of time, but not necessarily to maturity. Any decision to sell a security classified as available-for-sale would be based on various factors, including significant movements in interest rates, changes in maturity mix of assets and liabilities, income or liquidity needs, regulatory considerations and other factors. Debt securities available-for-sale are carried at fair value, with unrealized gains and losses, net of taxes, reported as a component of accumulated other comprehensive income in shareholders' equity. Premiums and discounts are recognized in interest income using the interest method over the estimated life of the security. Realized gains and losses from the sale of available-for-sale securities are computed on the basis of specific identification of the adjusted cost of each security and are shown net as a separate line item in the statement of income.  Declines in the fair value of available-for-sale securities below their cost that are deemed to be other-than-temporary are reflected in earnings as realized losses. In estimating other-than-temporary impairment losses, management must first assess whether (a) it has the intent to sell the security and (b) it is more likely than not that it will be required to sell the security prior to its anticipated recovery. These steps are done before assessing whether the cost basis of the investment will be recovered. The assessment of the probability of recovery would consider, among other things, the length of time and the extent to which the fair value has been less than cost and the financial condition and near-term prospects of the issuer. More information about investment securities is provided in Note 3 – Securities.  Restricted Investment in Bank Stocks Restricted stock, which represents required investments in the common stock of correspondent banks, is carried at cost and, as of December 31, 2019 and 2018 consisted primarily of the common stock of the Federal Home Loan Bank of Pittsburgh (FHLBP) and, to a lesser degree, Atlantic Community Bancshares, Inc. (ACBI), the parent company of Atlantic Community Bankers Bank (ACBB). Under the FHLBP’s Capital Plan, PeoplesBank is required to maintain a minimum member stock investment, both as a condition of becoming and remaining a member and as a condition of obtaining borrowings from the FHLBP. The FHLBP uses a formula to determine the minimum stock investment, which is based on the volume of loans outstanding, unused borrowing capacity and other factors. The FHLBP paid dividends during the years ended December 31, 2019 and 2018 . The FHLBP restricts the repurchase of the excess capital stock of member banks. The amount of excess capital stock that can be repurchased from any member is currently the lesser of five percent of the member’s total capital stock outstanding or its excess capital stock outstanding.  Management evaluates the restricted stock for impairment in accordance with FASB ASC Topic 942. Management’s determination of whether these investments are impaired is based on their assessment of the ultimate recoverability of their cost rather than by recognizing temporary declines in value. Using the FHLBP as an example, the determination of whether a decline affects the ultimate recoverability of cost is influenced by criteria such as: (1) the significance of the decline in net assets of the FHLBP as compared to the capital stock amount for the FHLBP and the length of time this situation has persisted; (2) commitments by the FHLBP to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLBP; and (3) the impact of legislative and regulatory changes on institutions and, accordingly, on the customer base of the FHLBP. Management believes no impairment charge was necessary related to the restricted stock during the periods ended December 31, 2019 and 2018 . Loans Held for Sale Loans held for sale are comprised of residential mortgage loans and the guaranteed portion of secondary-market qualified Small Business Administration loans. Loans held for sale are reported at the lower of cost or fair value, as determined by the aggregate commitments from investors or current investor yield requirements. The amount by which cost exceeds fair value, if any, is accounted for as a valuation allowance and is charged to expense in the period of the change. The Company generally sells the guaranteed portion of its SBA loans to a third party and retains the servicing, holding the nonguaranteed portion in its portfolio. Gains or losses recognized on the sale of mortgage loans and loans guaranteed by the Small Business Administration loans are recognized based on the difference between the selling price and the carrying value of the related loan and are recorded in noninterest income.  Loans Loans receivable that management has the intent and ability to hold for the foreseeable future or until maturity or payoff, are stated at their outstanding unpaid principal balances less amounts charged off, net of an allowance for loan losses and any deferred fees or costs. Interest income is accrued on the unpaid principal balance. Generally, loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the yield (interest income) over the contractual life of the loan. The loans receivable portfolio is segmented into commercial and consumer loans. Commercial loans consist of the following industry classes: builder & developer, commercial real estate investor, residential real estate investor, hotel/motel, wholesale & retail, agriculture, manufacturing and all other. Consumer loans consist of the following classes: residential mortgage, home equity and all other.  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 is currently performing. A loan may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. When a loan is placed on nonaccrual status, unpaid interest credited to income in the current year is reversed and unpaid interest accrued in prior years is charged against the allowance for loan losses. Interest received on nonaccrual loans, including impaired loans, generally is either applied against principal or reported as interest income, according to the Corporation’s judgment as to the collectability of principal. Generally, loans are restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time, generally six months, and the ultimate collectability of the total contractual principal and interest is no longer in doubt. The past due status of all classes of loans receivable is determined based on contractual due dates for loan payments.  Allowance for Loan Losses The allowance for loan losses represents the Corporation’s estimate of losses inherent in the loan portfolio as of the balance sheet date and is recorded as a reduction to loans. The allowance for loan losses is increased by the provision for loan losses, and decreased by charge-offs, net of recoveries. Loans deemed to be uncollectable are charged against the allowance for loan losses, and subsequent recoveries, if any, are credited to the allowance. All, or part, of the principal balance of loans receivable are charged off to the allowance as soon as it is determined that the repayment of all, or part, of the principal balance is highly unlikely. While the Corporation attributes a portion of the allowance to individual loans and groups of loans that it evaluates and determines to be impaired, the allowance is available to cover all charge-offs that arise from the loan portfolio.  The allowance for loan losses is maintained at a level considered adequate to provide for losses that can be reasonably anticipated. The Corporation performs a quarterly evaluation of the adequacy of the allowance. The allowance is based on the Corporation’s past loan loss experience, known and inherent risks in the portfolio, adverse situations that may affect the borrower’s ability to repay, the estimated value of any underlying collateral, composition of the loan portfolio, current economic conditions and other relevant factors. This evaluation is inherently subjective as it requires material estimates that may be susceptible to significant revision as more information becomes available. The allowance consists of specific, general and unallocated components. The specific component relates to loans that are classified as impaired, generally substandard and nonaccrual loans. For loans that are classified as impaired, an allowance is established when the collateral value (or discounted cash flows or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers pools of loans by loan class including commercial loans not considered impaired, as well as smaller balance homogeneous loans, such as residential real estate, home equity and other consumer loans. These pools of loans are evaluated for loss exposure based upon historical loss rates for each of these classes of loans, adjusted for qualitative (environmental) risk factors. Historical loss rates are based on a two year rolling average of net charge-offs. Qualitative risk factors that supplement historical losses in the evaluation of loan pools are shown below. Each factor is assigned a value to reflect improving, stable or declining conditions based on the Corporation’s best judgment using relevant information available at the time of the evaluation.  ·  Changes in international, US, 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 ·  Impact of imposed tariffs  The unallocated component is maintained to cover uncertainties that could affect the Corporation’s estimate of probable losses. For example, increasing credit risk and uncertainties, not yet reflected in current leading indicators, associated with prolonged low economic growth, or recessionary business conditions for certain industries or the broad economy, or the erosion of real estate values, represent risk factors, the occurrence of any or all of which can adversely affect a borrowers’ ability to service their loans. The unallocated component of the allowance also reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the loan portfolio, including the unpredictable timing and amounts of charge-offs and related historical loss averages, and specific-credit or broader portfolio future cash flow value and collateral valuation uncertainties which could negatively impact unimpaired portfolio loss factors.  As disclosed in Note 4-Loans, the Corporation engages in commercial and consumer lending. Loans are made within the Corporation’s primary market area and surrounding areas, and include the purchase of whole loan or participation interests in loans from other financial institutions. Commercial loans, which pose the greatest risk of loss to the Corporation, whether originated or purchased, are generally secured by real estate. Within the broad commercial loan segment, the builder & developer and commercial real estate investor loan classes generally present a higher level of risk than other commercial loan classifications. This greater risk is due to several factors, including the concentration of principal in a limited number of loans and borrowers, the effect of general economic conditions on income producing properties, unstable real estate prices and the dependency upon successful construction and sale or operation of the real estate project. Within the consumer loan segment, junior (i.e., second) liens present a slightly higher risk to the Corporation because economic and housing market conditions can adversely affect the underlying value of the collateral and the ability of some borrowers to service their debt.  A loan is considered impaired when, based on current information and events, it is probable that the Corporation will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered in determining impairment include payment status and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. The Corporation determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. Loans that are deemed impaired are evaluated for impairment loss based on the net realizable value of the collateral, as applicable. Loans that are not collateral dependent will rely on the present value of expected future cash flows discounted at the loan’s effective interest rate to determine impairment loss. Large groups of smaller balance homogeneous loans such as residential mortgage loans, home equity loans and other consumer loans are collectively evaluated for impairment, unless they are classified as impaired.  An allowance for loan losses is established for an impaired commercial loan if its carrying value exceeds its estimated fair value. For commercial loans secured by real estate, estimated fair values are determined primarily through third-party appraisals of the underlying collateral. When a real estate secured loan becomes impaired, a decision is made regarding whether an updated certified appraisal of the real estate is necessary. This decision is based on various considerations, including the age of the most recent appraisal, the loan-to-value ratio based on the most recent appraisal and the condition of the property. Appraisals are generally discounted to provide for selling costs and other factors to determine an estimate of the net realizable value of the property. For commercial loans secured by non-real estate collateral, such as accounts receivable, inventory and equipment, estimated fair values are determined based on the borrower’s financial statements, inventory reports, accounts receivable aging or equipment appraisals or invoices. Indications of value from these sources are generally discounted based on the age of the financial information or the quality of the assets. In instances when specific consumer related loans become impaired, they may be partially or fully charged off, which obviates the need for a specific allowance.  Loans whose terms are modified are classified as troubled debt restructurings if the Corporation grants borrowers experiencing financial difficulties concessions that it would not otherwise consider. Concessions granted under a troubled debt restructuring may involve an interest rate that is below the market rate given the associated credit risk of the loan or an extension of a loan’s stated maturity date. Loans classified as troubled debt restructurings are designated as impaired. Non-accrual troubled debt restructurings are restored to accrual status if principal and interest payments, under the modified terms, are current for a reasonable period of time, generally six consecutive months after modification and future payments are reasonably assured. Banking regulatory agencies, as an integral part of their examination process, periodically review the Corporation’s allowance for loan losses and may require the Corporation to recognize additions to the allowance based on their judgments about information available to them at the time of their examination, which may not be currently available to the Corporation. Based on a comprehensive analysis of the loan portfolio, the Corporation believes that the level of the allowance for loan losses at December 31, 2019 is adequate.  Transfers of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Corporation, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Corporation does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Premises and Equipment Land is carried at cost. Premises and equipment are carried at cost less accumulated depreciation. Depreciation expense is calculated principally on the straight-line method over the assets’ estimated useful lives. Estimated useful lives are five to forty years for buildings and improvements, five to twenty years for furniture and equipment and two to seven years for computer equipment and software. Maintenance and repairs are charged to expense as incurred. The cost of significant improvements to existing assets is capitalized and amortized over the shorter of the asset’s useful life or related lease term. When facilities are retired or otherwise disposed of, the depreciated cost is removed from the asset accounts, and any gain or loss is reflected in the statement of income.  Foreclosed Real Estate Foreclosed real estate, included in other assets, is comprised of property acquired through a foreclosure proceeding or property that is acquired through in substance foreclosure. Foreclosed real estate is initially recorded at fair value minus estimated costs to sell at the date of foreclosure, establishing a new cost basis. Any difference between the carrying value and the new cost basis is charged against the allowance for loan losses. Appraisals, obtained from an independent third party, are generally used to determine fair value. After foreclosure, management reviews valuations at least quarterly and adjusts the asset to the lower of cost or fair value minus estimated costs to sell through a valuation allowance or a charge-off. Costs related to the improvement of foreclosed real estate are generally capitalized until the real estate reaches a saleable condition subject to fair value limitations. Revenue and expense from operations and changes in the valuation allowance are included in noninterest expense. When a foreclosed real estate asset is ultimately sold, any gain or loss on the sale is included in the income statement as a component of noninterest expense. At December 31, 2019 , foreclosed real estate was $ 797,000 , which included no residential real estate, compared to $1,755,000 in foreclosed real estate, which included $18,000 of residential real estate, at December 31, 2018 . Included within loans receivable as of December 31, 2019 , was a recorded investment of $ 407,000 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.  Bank Owned Life Insurance PeoplesBank invests in bank owned life insurance (BOLI) as a source of funding for employee benefit expenses. BOLI involves the purchasing of life insurance by PeoplesBank on a select group of employees and members of the board of directors. PeoplesBank is the owner and beneficiary of the policies. This life insurance investment is carried at the cash surrender value of the underlying policies and is included in other assets in the amount of $45,647,000 at December 31, 2019 , compared to $37,585,000 at December 31, 2018 .  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 which was $257,000 , $213,000 , and $128,000 in 2019 , 2018 and 2017 , respectively. Mortgage servicing income is included in other income on the consolidated statements of income. The MSR asset is evaluated periodically for impairment and carried at the lower of amortized cost or fair value. A third party calculates fair value by discounting the estimated cash flows from servicing income using a rate consistent with the risk associated with these assets and an expected life commensurate with the expected life of the underlying loans. In the event that the amortized cost of the MSR asset exceeds the fair value of the asset, a valuation allowance would be established through a charge against servicing income. Subsequent fair value evaluations may determine that impairment has been reduced or eliminated, in which case the valuation allowance would be reduced through a credit to earnings. At December 31, 2019 , the balance of residential mortgage loans serviced for third parties was $115,620,000 compared to $98,852,000 at December 31, 2018 .  The following table summarizes the changes in MSRs, which are included in other assets on the consolidated balance sheets.     Years ended December 31,  (dollars in thousands) 2019 2018  Amortized cost:  Balance at beginning of year $ 925 $ 672  Originations of mortgage servicing rights 277 386  Amortization expense (220) (133)  Valuation allowance (17) 0  Balance at end of year $ 965 $ 925    Trust and Investment Services Assets Assets held by PeoplesBank in a fiduciary or agency capacity for its clients are not included in the consolidated balance sheets since these items are not assets of PeoplesBank. At December 31, 2019 , the market value of assets was $ 899,876,000 compared to $725,087,000 at December 31, 2018 .  Advertising Advertising costs are charged to expense when incurred.  Income Taxes Deferred income taxes are provided on the liability method whereby deferred tax assets are recognized for deductible temporary differences and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax basis. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted through the provision for income taxes for the effects of changes in tax laws and rates on the effective date.  The Corporation accounts for uncertain tax positions as required by FASB ASC Topic 740. FASB ASC Topic 740 clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements. Specifically, the accounting standard prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return as well as guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. No significant income tax uncertainties have been identified by the Corporation; therefore, the Corporation recognized no adjustment for unrecognized income tax benefits for the years ended December 31, 2019 and 2018 . The Corporation’s policy is to recognize interest and penalties on unrecognized tax benefits in income taxes expense in the Consolidated Statement of Income. The tax years subject to examination by the taxing authorities are the years ended December 31, 2018 , 2017 , and 2016 .   Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the evaluation of other-than-temporary impairment losses for investment securities and the evaluation of impairment losses for foreclosed real estate.  Fair Value of Financial Instruments Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in Note 16 – Fair Value Measurements and Fair Values of Financial Instruments. Fair value estimates involve uncertainties and matters of significant judgment. Changes in assumptions or in market conditions could significantly affect the estimates.  Goodwill and Core Deposit Intangible Assets Goodwill arising from acquisitions is not amortized, but is subject to an annual impairment test. This test consists of a qualitative analysis. If the Corporation determines events or circumstances indicate that it is more likely than not that goodwill is impaired, a quantitative analysis must be completed. Analyses may also be performed between annual tests. Significant judgment is applied when goodwill is assessed for impairment. This judgment includes developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables, incorporating general economic and market conditions, and selecting an appropriate control premium. The Corporation completes its annual goodwill impairment test on October 1 st of each year. Based upon the analysis, the Corporation concluded that the amount of recorded goodwill was not impaired as of October 1, 2019.  Core deposit intangibles represent the value assigned to demand, interest checking, money market, and savings accounts acquired as part of an acquisition. The core deposit intangible value represents the future economic benefit of potential cost savings from acquiring core deposits as part of an acquisition compared to the cost of alternative funding sources and the alternative cost to grow a similar core deposit base. The core deposit intangible asset resulting from the merger with Madison Bancorp, Inc. was determined to have a definite life and is being amortized using the sum of the years’ digits method over ten years. All intangible assets must be evaluated for impairment if certain events or changes in circumstances occur. Any impairment write-downs would be recognized as expense on the consolidated statements of income.  At December 31, 2019 , 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. Results for reporting periods beginning after January 1, 2018 are presented under ASC 606, while prior period amounts were not adjusted and continue to be reported in accordance with the previous accounting guidance under ASC 605.  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. The Corporation’s performance obligations are generally satisfied, and the related revenue recognized, over the period in which the service is provided. Payment for services rendered is primarily received in the following month.  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 in which case revenues are recognized utilizing the expected value method. Payment for services rendered is primarily received in the following month.  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. Other service charges include revenue from proce

Securities [Abstract]
Securities	NOTE 3-Securities  A summary of securities, available-for-sale at December 31, 2019 and 2018 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 December 31, 2019 , 88 percent of the fair value of the municipal bond portfolio was concentrated in the Commonwealth of Pennsylvania, the portfolio was intentionally distributed to limit exposure with the largest issuer at $2.3 million.

The analysis considers, among other factors: 1) whether the Corporation has the intent to sell its securities prior to market recovery or maturity; 2) whether it is more likely than not that the Corporation will be required to sell its securities prior to market recovery or maturity; 3) default rates/history by security type; 4) third-party securities ratings; 5) third-party guarantees; 6) subordination; 7) payment delinquencies; 8) nature of the issuer; and 9) current financial news.  The Corporation believes that any unrealized losses at December 31, 2019 were primarily the result of changes in market interest rates and that it has the ability to hold these investments for a time necessary to recover the amortized cost. Through December 31, 2019 , the Corporation has collected all interest and principal on its investment securities as scheduled. The Corporation believes that collection of the contractual principal and interest is probable and, therefore, all impairment is considered to be temporary.

Loans [Abstract]
Loans	 NOTE 4-Loans Loan Portfolio Composition  The table below provides the composition of the loan portfolio at December 31, 2019 and 2018 . 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.     December 31, % Total December 31, % Total  (dollars in thousands) 2019 Loans 2018 Loans  Builder & developer $ 159,312 10.6 $ 154,977 10.4  Commercial real estate investor 207,227 13.8 210,501 14.2  Residential real estate investor 247,969 16.5 231,118 15.6  Hotel/Motel 80,260 5.3 77,480 5.2  Wholesale & retail 109,238 7.3 117,280 7.9  Manufacturing 86,511 5.7 80,075 5.4  Agriculture 80,719 5.4 65,540 4.4  Other 313,371 20.7 342,839 23.0  Total commercial related loans 1,284,607 85.3 1,279,810 86.1  Residential mortgages 94,868 6.3 83,977 5.7  Home equity 100,827 6.7 98,019 6.6  Other 24,833 1.7 23,874 1.6  Total consumer related loans 220,528 14.7 205,870 13.9  Total loans $ 1,505,135 100.0 $ 1,485,680 100.0  Concentrations of Credit Risk  Concentrations of credit risk arise when a number of clients are engaged in similar business activities in the same geographic region or have similar economic features that could cause their ability to meet contractual obligations to be similarly affected by changes in economic conditions. Most of the Corporation's business is with clients in south central Pennsylvania, specifically York County and Lancaster County and north central Maryland, specifically Baltimore County, Harford County and Baltimore City. Although this focus may pose a concentration risk geographically, the Corporation believes that the diverse local economy and our detailed knowledge of the client base lessens this risk. At December 31, 2019 , the Corporation had three industry concentrations that exceeded 10 percent of the total loan portfolio : residential real estate investor, which represented 16.5 percent of the portfolio; commercial real estate investor, which represented 13.8 percent of the portfolio; and builder & developer, which represented 10.6 percent of the portfolio. At December 31, 2018 , the Corporation had three industry concentrations that exceeded 10 percent of the total loan portfolio : residential real estate investor, which represented 15.6 percent of the portfolio; commercial real estate investor, which represented 14.2 percent of the portfolio; and builder & developer, which represented 10.4 percent of the portfolio. Loans to borrowers within these industries are usually collateralized by real estate.  The principal balance of outstanding loans to directors, executive officers, principal shareholders and any affiliates of such persons was $ 9,355,000 at December 31, 2019 and $7,502,000 at December 31, 2018 . During 2019 , total additions were $ 2,944,000 and total repayments and reductions were $1,091,000 . As of year-end 2019 , all loans to this group were current and performing in accordance with contractual terms.  Loan Risk Ratings  The Corporation’s internal risk rating system follows regulatory guidance as to risk classifications and definitions. Every approved loan is assigned a risk rating. Generally, risk ratings for commercial related loans and residential mortgages held for investment are determined by a formal evaluation of risk factors performed by the Corporation’s underwriting staff. For consumer loans, and commercial loans up to $500,000 , the Corporation uses third-party credit scoring software models for risk rating purposes. The loan portfolio is monitored on a continuous basis by loan officers, loan review personnel and senior management. Adjustments of loan risk ratings are generally performed by the Special Asset Committee, which includes senior management. The Committee, which typically meets at least 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. In addition to review by the Committee, existing loans are monitored by the primary loan officer and loan review to determine if any changes, upward or downward, in risk ratings are appropriate. Primary loan officers and loan review may downgrade existing loans, except to non-accrual status. Only the Committee, Executive Chairman or President/CEO may upgrade a loan that is classified.  The Corporation uses ten risk ratings to grade commercial loans. The first seven ratings, representing the lowest risk, are combined and given a “pass” rating. A pass rating is a satisfactory credit rating, which applies to a loan that is expected to perform in accordance with the loan agreement and has a low probability of loss. A loan rated “special mention” has a potential weakness which may, if not corrected, weaken the loan or inadequately protect the Corporation’s position at some future date. A loan rated “substandard” is inadequately protected by the current net worth or paying capacity of the borrower, or of the collateral pledged. A “substandard” loan has a well-defined weakness or weaknesses that could jeopardize liquidation of the loan, which exposes the Corporation to loss if the deficiencies are not corrected. When circumstances indicate that collection of the loan is doubtful, the loan is risk-rated “nonaccrual,” the accrual of interest income is discontinued, and any unpaid interest previously credited to income is reversed. The table below does not include the regulatory classification of “doubtful,” nor does it include the regulatory classification of “loss”, because the Corporation promptly charges off loan losses.

As of December 31, 2019, generally, impaired loans are all loans risk rated nonaccrual or classified as troubled debt restructurings. As of December 31, 2018, generally, impaired loans are certain loans risk rated substandard and all loans risk rated nonaccrual or classified as troubled debt restructuring. An allowance is established for those individual loans that are commercial related where the Corporation has doubt as to full recovery of the outstanding principal balance. Typically, impaired consumer related loans are partially or fully charged-off eliminating the need for a specific allowance. The recorded investment represents outstanding unpaid principal loan balances adjusted for payments collected on a non-cash basis and charge-offs.

Concessions granted with respect to these loans involve an extension of the maturity date or a below market interest rate relative to new debt with similar credit risk. Generally, these loans are secured by real estate. If repayment of the loan is determined to be collateral dependent, the loan is evaluated for impairment loss based on the fair value of the collateral. For loans that are not collateral dependent, the present value of expected future cash flows, discounted at the loan’s original effective interest rate, is used to determine any impairment loss. A nonaccrual TDR represents a nonaccrual loan, as previously defined, which includes an economic concession. Nonaccrual TDRs are restored to accrual status if principal and interest payments, under the modified terms, are current for six consecutive payments after the modification and future principal and interest payments are reasonably assured. In contrast, an accruing TDR represents a loan that, at the time of the modification, has a demonstrated history of payments and with respect to which management believes that future loan payments are reasonably assured under the modified terms.  The table below shows loans whose terms have been modified under TDRs during the years ended December 31, 2019 and 2018 . There were no impairment loss recognized on any of these TDRs. There were no defaults during the year ended December 31, 2019 for TDRs entered into during the previous 12 month period.

Premises, Equipment and Leases [Abstract]
Premises, Equipment and Leases	NOTE 6-Premises, Equipment and Leases  The following table presents a summary of premises and equipment as of December 31, 2019 and 2018 .     (dollars in thousands) 2019 2018  Land $ 5,093 $ 4,829  Buildings and improvements 26,874 26,172  Financing lease right-of-use assets 1,134 0  Equipment 23,056 21,519  56,157 52,520  Less accumulated depreciation/amortization (30,190) (27,796)  Premises and equipment, net $ 25,967 $ 24,724  A lease is defined as a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. On January 1, 2019, the Corporation adopted ASU 2016-02 “ Leases” (Topic 842) and all subsequent ASUs that modified Topic 842. For the Corporation, Topic 842 affected the accounting treatment for operating lease agreements in which the Corporation is the lessee. Substantially all of the leases in which the Corporation is the lessee are comprised of real estate property, ATM locations, and office space. Substantially all of our leases are classified as operating leases, and therefore, were previously not recognized on the Corporation’s consolidated statements of condition. With the adoption of Topic 842, operating lease agreements are required to be recognized on the consolidated statements of condition as a right-of-use (“ROU”) asset and a corresponding lease liability. The Corporation has one finance lease for one financial center. Leases with an initial term of 12 months or less are not recorded on the consolidated statement of condition. The leases have remaining lease terms of 1 year to 25 years, some of which include options to extend. Upon opening a new financial center, we typically install brand-specific leasehold improvements which are depreciated over the shorter of the useful life or length of the lease. To the extent that the initial lease term of the related lease is less than the useful life of the leasehold improvements and, taking into consideration the dollar amount of the improvements, we conclude that it is reasonably certain that a renewal option will be exercised, the renewal period is included in the lease term, and the related payments are reflected in the ROU asset and lease liability. Regarding the discount rate, Topic 842 requires the use of the rate implicit in the lease whenever this rate is readily determinable. As this rate is rarely determinable, the Corporation utilizes its incremental borrowing rate at lease inception, on an amortizing and collateralized basis, over a similar term. For operating leases existing prior to January 1, 2019, the rate for the remaining lease term as of January 1, 2019 was used. For the Corporation’s financing leases, the Corporation utilized its incremental borrowing rate at lease inception. All of our leases include fixed rental payments. We commonly enter into leases under which the lease payments increase at pre-determined dates based on the change in the consumer price index. While the majority of our leases are gross leases, we also have a number of leases in which we make separate payments to the lessor based on the lessor’s property and casualty insurance cost and the property taxes assessed on the property, as well as a portion of the common area maintenance associated with the property. We have elected the practical expedient not to separate lease and nonlease components for all of our building leases.      The Components of lease expense were as follows:     Twelve months ended  December 31, 2019  (dollars in thousands)  Operating lease cost $ 760   Finance lease cost:  Amortization of right-of-use assets $ 69  Interest on lease liability 53  Total finance lease cost $ 122   Total lease cost $ 882  Supplemental cash flow information related to leases were as follows:     Twelve months ended  December 31, 2019   Operating cash flows from operating leases $ 783  Operating cash flows from financing leases 53  Financing cash flows from financing leases 40   Right-of-use assets obtained in exchange for lease obligations:  Operating leases 1,019  Finance leases 0  Amounts recognized as right-of-use assets related to finance leases are included in fixed assets in the accompanying statement of financial position, while related lease liabilities are included in long-term debt.

Short-Term Borrowings And Long-Term Debt	NOTE 8-Short-term Borrowings and Long-term Debt  The schedule below provides a summary of short-term borrowings that consist of securities sold under agreements to repurchase, federal funds purchased and other borrowings. Securities sold under agreements to repurchase are overnight borrowings between PeoplesBank and its commercial depositors and are subject to daily repricing. Federal Funds purchased from correspondent banks mature in one business day and reprice daily based on the Federal Funds rate. As of December 31, 2019 , PeoplesBank’s total availability under Federal Funds lines was $13,000 , 000 . Other short-term borrowings consist of credit available through the Federal Home Loan Bank of Pittsburgh (FHLBP). PeoplesBank maintains a line-of-credit (Open Repo Plus) with the FHLBP which is a revolving term commitment used on an overnight basis. The term of this commitment may not exceed 364 days and it reprices daily at market rates. Under terms of a blanket collateral agreement with the FHLBP, the line-of-credit and long term advances are secured by FHLBP stock and qualifying real estate secured loans. As of December 31, 2019 , PeoplesBank’s total availability was $445,066,800 with the FHLBP.  The Corporation maintains a $3,000,000 line of credit with ACNB Bank to provide a source of liquidity. The line, renewable annually, is secured by a first lien on the Codorus Valley Corporate Center. The interest rate on the ACNB Bank line is Wall Street Journal Prime. No draws have been made on the line and on December 31, 2019 and 2018 , the balance was zero .

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

Benefit Plans [Abstract]
Benefit Plans	 NOTE 11- Benefit Plans  Defined Contribution Plan PeoplesBank maintains a 401(k) savings and investment plan covering substantially all employees. Under the plan, employees can contribute a percentage of their compensation subject to certain limits based on federal tax law. In 2019, 2018, and 2017, PeoplesBank made 100 percent matching contributions up to the first 4 percent of each employee’s compensation contributed to the plan, and both the employee and employer contributions vest immediately. PeoplesBank's expense for the 401(k) savings and investment plan was $676,000 for 2019, $590,000 for 2018, and $587,000 for 2017.  PeoplesBank established a supplemental defined contribution deferred compensation plan for one executive in 2019. Under the plan, PeoplesBank contributes a percentage of compensation to the executive. PeoplesBank’s expense for the defined contribution deferred compensation plan was $60,000 which includes interest of $3,000 . The accrued liability for the defined contribution deferred compensation plan was $60,000 at December 31, 2019.  Supplemental Benefit Plans PeoplesBank maintains supplemental retirement plans for selected executives. The expense associated with these plans was approximately $371,000 for 2019 , $261,000 for 2018 and $256,000 for 2017 . The accrued liability for the supplemental retirement plans was $4,264,000 at December 31, 2019 and $4,140,000 at December 31, 2018 . Income earned from bank owned life insurance policies was used to finance the cost of supplemental benefit plans, and provide a tax-exempt return to PeoplesBank.  Directors Post Retirement Split-dollar Life Insurance Benefit PeoplesBank recorded net expense of $40,000 in 2019 , $43,000 in 2018 and $39,000 in 2017 , on bank owned life insurance policies with a post retirement split-dollar life insurance benefit.

Restricted awards are granted at fair value. 1,106 , 1,098 and 954 restricted shares granted in 2019, 2018 and 2017, respectively, vest 100% four years from the date of grant. All of the remaining restricted shares granted in 2019 , 2018 and 2017 vest as follows: one-third at the end of the first year from the date of grant; one-third at the end of the second year from the date of grant; and one-third at the end of the third year from the date of grant. Restricted stock awards are participating securities but have no impact on basic EPS at December 31, 2019 and 2018. The plans also permit the granting of stock awards. Upon exercise and/or award, the Corporation has historically issued treasury stock, if available, and/or authorized, but unissued, common stock to satisfy the options/awards.  The following table presents compensation expense and related tax benefits for stock option, restricted stock and stock awards recognized on the consolidated statement of income.

Under FASB ASC Topic 718, tax benefits are only recognized over the vesting period for options that ordinarily will generate a tax deduction when exercised (non-qualified stock options) and restricted stock awards.  The Corporation granted the following stock options, restricted stock and stock awards during the years ended December 31, 2019 , 2018 and 2017 , as adjusted for stock dividends.     2019 2018 2017  Nonqualified stock options 0 17,924 17,085  Restricted stock 14,872 21,507 16,504  Stock award 6,195 7,766 9,065  The weighted average grant-date fair value and weighted average assumptions used to determine the fair value using the Black-Scholes valuation model for the stock options granted are presented below, as adjusted for stock dividends.

Commitments [Abstract]
Commitments	NOTE 14-Commitments  In the normal course of business, the Corporation is a party to various financial transactions that are not funded as of the balance sheet date. Off-balance sheet financial instruments, which enable PeoplesBank clients to meet their financing needs, are comprised mainly of commitments to extend credit and standby letters of credit. Standby letters of credit are written conditional commitments issued by PeoplesBank to guarantee the performance of a client to a third party. The credit and market risk involved in issuing letters of credit is essentially the same as that involved in extending other loan commitments. To manage these risks, the Corporation uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments and requires collateral to support these letters of credit as deemed necessary. Management believes that the proceeds obtained through a liquidation of such collateral would be sufficient to cover the maximum potential amount of future payments required under the corresponding guarantees. The amount of the liability as of December 31, 2019 and 2018, for guarantees under standby letters of credit issued was considered not material by management. Normally, commitments to extend credit and letters of credit have fixed expiration dates or termination clauses, have specific rates and are for specific purposes. Many of the commitments are expected to expire without being extended; therefore, total commitment amounts do not necessarily represent future cash requirements.  A summary of outstanding commitments at December 31, 2019 and 2018 is shown below.

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

Fair value is generally determined based upon independent third-party appraisals of the properties, or discounted cash flows based upon the expected proceeds. These loans are included as Level 3 fair values, based on the lowest level of input that is significant to the fair value measurements. At December 31, 2019 , the fair value consists of impaired loan balances of $11,297,000 , net of valuation allowances of $7,420,000 and charge-offs of $134,000 , compared to impaired loan balances of $13,297,000 , net of valuation allowances of $3,679,000 and charge-offs of $134,000 , at December 31, 2018 .  Foreclosed Real Estate Other real estate property acquired through foreclosure is initially recorded at fair value of the property at the transfer date less estimated selling cost. Subsequently, other real estate owned is carried at the lower of its carrying value or the fair value less estimated selling cost. Fair value is usually determined based upon an independent third-party appraisal of the property or occasionally upon a recent sales offer. At December 31, 2019, the fair value of foreclosed real estate with a valuation allowance or write-down was $797,000 which is net of write-downs of $617,000 . At December 31, 2018 there were no foreclosed real estate assets with a valuation allowance or write-down.

Assets And Liabilities Subject To Offsetting	Note 17—Assets and Liabilities Subject to Offsetting  Securities Sold Under Agreements to Repurchase PeoplesBank enters into agreements with 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.

Summary Of Significant Accounting Policies [Abstract]
Nature of Operations and Basis of Presentation	Nature of Operations and Basis of Presentation Codorus Valley Bancorp, Inc. (“Corporation” or “Codorus Valley”) is a one-bank holding company headquartered in York, Pennsylvania that provides a full range of banking services through its subsidiary, PeoplesBank, A Codorus Valley Company (“PeoplesBank” or “Bank”). PeoplesBank operates two wholly-owned subsidiaries as of December 31, 2019 . The subsidiaries consist of Codorus Valley Financial Advisors, Inc. d/b/a Peoples Wealth Advisors, which sells non-deposit investment products and SYC Settlement Services, Inc., which provides real estate settlement services. 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 reportable period of 2019 . The accounts of CVB Statutory Trust No. 1 and No. 2 are not included in the consolidated financial statements as discussed in Note 8 – Short-term Borrowings and Long-term Debt. All significant intercompany account balances and transactions have been eliminated in consolidation. The accounting and reporting policies of Codorus Valley and subsidiaries conform to accounting principles generally accepted in the United States of America and have been followed on a consistent basis.
Reclassification	Reclassifications Certain amounts in the 2018 and 2017 consolidated financial statements and notes have been reclassified to conform to the 2019 presentation.
Investment Securities	Investment Securities The classification of securities is determined at the time of acquisition and is reevaluated at each reporting date. Securities classified as available-for-sale are debt securities that the Corporation intends to hold for an indefinite period of time, but not necessarily to maturity. Any decision to sell a security classified as available-for-sale would be based on various factors, including significant movements in interest rates, changes in maturity mix of assets and liabilities, income or liquidity needs, regulatory considerations and other factors. Debt securities available-for-sale are carried at fair value, with unrealized gains and losses, net of taxes, reported as a component of accumulated other comprehensive income in shareholders' equity. Premiums and discounts are recognized in interest income using the interest method over the estimated life of the security. Realized gains and losses from the sale of available-for-sale securities are computed on the basis of specific identification of the adjusted cost of each security and are shown net as a separate line item in the statement of income.  Declines in the fair value of available-for-sale securities below their cost that are deemed to be other-than-temporary are reflected in earnings as realized losses. In estimating other-than-temporary impairment losses, management must first assess whether (a) it has the intent to sell the security and (b) it is more likely than not that it will be required to sell the security prior to its anticipated recovery. These steps are done before assessing whether the cost basis of the investment will be recovered. The assessment of the probability of recovery would consider, among other things, the length of time and the extent to which the fair value has been less than cost and the financial condition and near-term prospects of the issuer. More information about investment securities is provided in Note 3 – Securities.
Restricted Investment in Bank Stocks	Restricted Investment in Bank Stocks Restricted stock, which represents required investments in the common stock of correspondent banks, is carried at cost and, as of December 31, 2019 and 2018 consisted primarily of the common stock of the Federal Home Loan Bank of Pittsburgh (FHLBP) and, to a lesser degree, Atlantic Community Bancshares, Inc. (ACBI), the parent company of Atlantic Community Bankers Bank (ACBB). Under the FHLBP’s Capital Plan, PeoplesBank is required to maintain a minimum member stock investment, both as a condition of becoming and remaining a member and as a condition of obtaining borrowings from the FHLBP. The FHLBP uses a formula to determine the minimum stock investment, which is based on the volume of loans outstanding, unused borrowing capacity and other factors. The FHLBP paid dividends during the years ended December 31, 2019 and 2018 . The FHLBP restricts the repurchase of the excess capital stock of member banks. The amount of excess capital stock that can be repurchased from any member is currently the lesser of five percent of the member’s total capital stock outstanding or its excess capital stock outstanding.  Management evaluates the restricted stock for impairment in accordance with FASB ASC Topic 942. Management’s determination of whether these investments are impaired is based on their assessment of the ultimate recoverability of their cost rather than by recognizing temporary declines in value. Using the FHLBP as an example, the determination of whether a decline affects the ultimate recoverability of cost is influenced by criteria such as: (1) the significance of the decline in net assets of the FHLBP as compared to the capital stock amount for the FHLBP and the length of time this situation has persisted; (2) commitments by the FHLBP to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLBP; and (3) the impact of legislative and regulatory changes on institutions and, accordingly, on the customer base of the FHLBP. Management believes no impairment charge was necessary related to the restricted stock during the periods ended December 31, 2019 and 2018 .
Loans Held for Sale	Loans Held for Sale Loans held for sale are comprised of residential mortgage loans and the guaranteed portion of secondary-market qualified Small Business Administration loans. Loans held for sale are reported at the lower of cost or fair value, as determined by the aggregate commitments from investors or current investor yield requirements. The amount by which cost exceeds fair value, if any, is accounted for as a valuation allowance and is charged to expense in the period of the change. The Company generally sells the guaranteed portion of its SBA loans to a third party and retains the servicing, holding the nonguaranteed portion in its portfolio. Gains or losses recognized on the sale of mortgage loans and loans guaranteed by the Small Business Administration loans are recognized based on the difference between the selling price and the carrying value of the related loan and are recorded in noninterest income.
Loans	Loans Loans receivable that management has the intent and ability to hold for the foreseeable future or until maturity or payoff, are stated at their outstanding unpaid principal balances less amounts charged off, net of an allowance for loan losses and any deferred fees or costs. Interest income is accrued on the unpaid principal balance. Generally, loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the yield (interest income) over the contractual life of the loan. The loans receivable portfolio is segmented into commercial and consumer loans. Commercial loans consist of the following industry classes: builder & developer, commercial real estate investor, residential real estate investor, hotel/motel, wholesale & retail, agriculture, manufacturing and all other. Consumer loans consist of the following classes: residential mortgage, home equity and all other.  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 is currently performing. A loan may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. When a loan is placed on nonaccrual status, unpaid interest credited to income in the current year is reversed and unpaid interest accrued in prior years is charged against the allowance for loan losses. Interest received on nonaccrual loans, including impaired loans, generally is either applied against principal or reported as interest income, according to the Corporation’s judgment as to the collectability of principal. Generally, loans are restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time, generally six months, and the ultimate collectability of the total contractual principal and interest is no longer in doubt. The past due status of all classes of loans receivable is determined based on contractual due dates for loan payments.
Allowance for Loan Losses	Allowance for Loan Losses The allowance for loan losses represents the Corporation’s estimate of losses inherent in the loan portfolio as of the balance sheet date and is recorded as a reduction to loans. The allowance for loan losses is increased by the provision for loan losses, and decreased by charge-offs, net of recoveries. Loans deemed to be uncollectable are charged against the allowance for loan losses, and subsequent recoveries, if any, are credited to the allowance. All, or part, of the principal balance of loans receivable are charged off to the allowance as soon as it is determined that the repayment of all, or part, of the principal balance is highly unlikely. While the Corporation attributes a portion of the allowance to individual loans and groups of loans that it evaluates and determines to be impaired, the allowance is available to cover all charge-offs that arise from the loan portfolio.  The allowance for loan losses is maintained at a level considered adequate to provide for losses that can be reasonably anticipated. The Corporation performs a quarterly evaluation of the adequacy of the allowance. The allowance is based on the Corporation’s past loan loss experience, known and inherent risks in the portfolio, adverse situations that may affect the borrower’s ability to repay, the estimated value of any underlying collateral, composition of the loan portfolio, current economic conditions and other relevant factors. This evaluation is inherently subjective as it requires material estimates that may be susceptible to significant revision as more information becomes available. The allowance consists of specific, general and unallocated components. The specific component relates to loans that are classified as impaired, generally substandard and nonaccrual loans. For loans that are classified as impaired, an allowance is established when the collateral value (or discounted cash flows or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers pools of loans by loan class including commercial loans not considered impaired, as well as smaller balance homogeneous loans, such as residential real estate, home equity and other consumer loans. These pools of loans are evaluated for loss exposure based upon historical loss rates for each of these classes of loans, adjusted for qualitative (environmental) risk factors. Historical loss rates are based on a two year rolling average of net charge-offs. Qualitative risk factors that supplement historical losses in the evaluation of loan pools are shown below. Each factor is assigned a value to reflect improving, stable or declining conditions based on the Corporation’s best judgment using relevant information available at the time of the evaluation.  ·  Changes in international, US, 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 ·  Impact of imposed tariffs  The unallocated component is maintained to cover uncertainties that could affect the Corporation’s estimate of probable losses. For example, increasing credit risk and uncertainties, not yet reflected in current leading indicators, associated with prolonged low economic growth, or recessionary business conditions for certain industries or the broad economy, or the erosion of real estate values, represent risk factors, the occurrence of any or all of which can adversely affect a borrowers’ ability to service their loans. The unallocated component of the allowance also reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the loan portfolio, including the unpredictable timing and amounts of charge-offs and related historical loss averages, and specific-credit or broader portfolio future cash flow value and collateral valuation uncertainties which could negatively impact unimpaired portfolio loss factors.  As disclosed in Note 4-Loans, the Corporation engages in commercial and consumer lending. Loans are made within the Corporation’s primary market area and surrounding areas, and include the purchase of whole loan or participation interests in loans from other financial institutions. Commercial loans, which pose the greatest risk of loss to the Corporation, whether originated or purchased, are generally secured by real estate. Within the broad commercial loan segment, the builder & developer and commercial real estate investor loan classes generally present a higher level of risk than other commercial loan classifications. This greater risk is due to several factors, including the concentration of principal in a limited number of loans and borrowers, the effect of general economic conditions on income producing properties, unstable real estate prices and the dependency upon successful construction and sale or operation of the real estate project. Within the consumer loan segment, junior (i.e., second) liens present a slightly higher risk to the Corporation because economic and housing market conditions can adversely affect the underlying value of the collateral and the ability of some borrowers to service their debt.  A loan is considered impaired when, based on current information and events, it is probable that the Corporation will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered in determining impairment include payment status and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. The Corporation determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. Loans that are deemed impaired are evaluated for impairment loss based on the net realizable value of the collateral, as applicable. Loans that are not collateral dependent will rely on the present value of expected future cash flows discounted at the loan’s effective interest rate to determine impairment loss. Large groups of smaller balance homogeneous loans such as residential mortgage loans, home equity loans and other consumer loans are collectively evaluated for impairment, unless they are classified as impaired.  An allowance for loan losses is established for an impaired commercial loan if its carrying value exceeds its estimated fair value. For commercial loans secured by real estate, estimated fair values are determined primarily through third-party appraisals of the underlying collateral. When a real estate secured loan becomes impaired, a decision is made regarding whether an updated certified appraisal of the real estate is necessary. This decision is based on various considerations, including the age of the most recent appraisal, the loan-to-value ratio based on the most recent appraisal and the condition of the property. Appraisals are generally discounted to provide for selling costs and other factors to determine an estimate of the net realizable value of the property. For commercial loans secured by non-real estate collateral, such as accounts receivable, inventory and equipment, estimated fair values are determined based on the borrower’s financial statements, inventory reports, accounts receivable aging or equipment appraisals or invoices. Indications of value from these sources are generally discounted based on the age of the financial information or the quality of the assets. In instances when specific consumer related loans become impaired, they may be partially or fully charged off, which obviates the need for a specific allowance.  Loans whose terms are modified are classified as troubled debt restructurings if the Corporation grants borrowers experiencing financial difficulties concessions that it would not otherwise consider. Concessions granted under a troubled debt restructuring may involve an interest rate that is below the market rate given the associated credit risk of the loan or an extension of a loan’s stated maturity date. Loans classified as troubled debt restructurings are designated as impaired. Non-accrual troubled debt restructurings are restored to accrual status if principal and interest payments, under the modified terms, are current for a reasonable period of time, generally six consecutive months after modification and future payments are reasonably assured. Banking regulatory agencies, as an integral part of their examination process, periodically review the Corporation’s allowance for loan losses and may require the Corporation to recognize additions to the allowance based on their judgments about information available to them at the time of their examination, which may not be currently available to the Corporation. Based on a comprehensive analysis of the loan portfolio, the Corporation believes that the level of the allowance for loan losses at December 31, 2019 is adequate.
Transfers of Financial Assets	Transfers of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Corporation, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Corporation does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Premises and Equipment	Premises and Equipment Land is carried at cost. Premises and equipment are carried at cost less accumulated depreciation. Depreciation expense is calculated principally on the straight-line method over the assets’ estimated useful lives. Estimated useful lives are five to forty years for buildings and improvements, five to twenty years for furniture and equipment and two to seven years for computer equipment and software. Maintenance and repairs are charged to expense as incurred. The cost of significant improvements to existing assets is capitalized and amortized over the shorter of the asset’s useful life or related lease term. When facilities are retired or otherwise disposed of, the depreciated cost is removed from the asset accounts, and any gain or loss is reflected in the statement of income.
Foreclosed Real Estate	Foreclosed Real Estate Foreclosed real estate, included in other assets, is comprised of property acquired through a foreclosure proceeding or property that is acquired through in substance foreclosure. Foreclosed real estate is initially recorded at fair value minus estimated costs to sell at the date of foreclosure, establishing a new cost basis. Any difference between the carrying value and the new cost basis is charged against the allowance for loan losses. Appraisals, obtained from an independent third party, are generally used to determine fair value. After foreclosure, management reviews valuations at least quarterly and adjusts the asset to the lower of cost or fair value minus estimated costs to sell through a valuation allowance or a charge-off. Costs related to the improvement of foreclosed real estate are generally capitalized until the real estate reaches a saleable condition subject to fair value limitations. Revenue and expense from operations and changes in the valuation allowance are included in noninterest expense. When a foreclosed real estate asset is ultimately sold, any gain or loss on the sale is included in the income statement as a component of noninterest expense. At December 31, 2019 , foreclosed real estate was $ 797,000 , which included no residential real estate, compared to $1,755,000 in foreclosed real estate, which included $18,000 of residential real estate, at December 31, 2018 . Included within loans receivable as of December 31, 2019 , was a recorded investment of $ 407,000 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.
Bank Owned Life Insurance	Bank Owned Life Insurance PeoplesBank invests in bank owned life insurance (BOLI) as a source of funding for employee benefit expenses. BOLI involves the purchasing of life insurance by PeoplesBank on a select group of employees and members of the board of directors. PeoplesBank is the owner and beneficiary of the policies. This life insurance investment is carried at the cash surrender value of the underlying policies and is included in other assets in the amount of $45,647,000 at December 31, 2019 , compared to $37,585,000 at December 31, 2018 .
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 which was $257,000 , $213,000 , and $128,000 in 2019 , 2018 and 2017 , respectively. Mortgage servicing income is included in other income on the consolidated statements of income. The MSR asset is evaluated periodically for impairment and carried at the lower of amortized cost or fair value. A third party calculates fair value by discounting the estimated cash flows from servicing income using a rate consistent with the risk associated with these assets and an expected life commensurate with the expected life of the underlying loans. In the event that the amortized cost of the MSR asset exceeds the fair value of the asset, a valuation allowance would be established through a charge against servicing income. Subsequent fair value evaluations may determine that impairment has been reduced or eliminated, in which case the valuation allowance would be reduced through a credit to earnings. At December 31, 2019 , the balance of residential mortgage loans serviced for third parties was $115,620,000 compared to $98,852,000 at December 31, 2018 .  The following table summarizes the changes in MSRs, which are included in other assets on the consolidated balance sheets.     Years ended December 31,  (dollars in thousands) 2019 2018  Amortized cost:  Balance at beginning of year $ 925 $ 672  Originations of mortgage servicing rights 277 386  Amortization expense (220) (133)  Valuation allowance (17) 0  Balance at end of year $ 965 $ 925  
Trust and Investment Services Assets	Trust and Investment Services Assets Assets held by PeoplesBank in a fiduciary or agency capacity for its clients are not included in the consolidated balance sheets since these items are not assets of PeoplesBank. At December 31, 2019 , the market value of assets was $ 899,876,000 compared to $725,087,000 at December 31, 2018 .
Advertising	Advertising Advertising costs are charged to expense when incurred.
Income Taxes	Income Taxes Deferred income taxes are provided on the liability method whereby deferred tax assets are recognized for deductible temporary differences and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax basis. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted through the provision for income taxes for the effects of changes in tax laws and rates on the effective date.  The Corporation accounts for uncertain tax positions as required by FASB ASC Topic 740. FASB ASC Topic 740 clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements. Specifically, the accounting standard prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return as well as guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. No significant income tax uncertainties have been identified by the Corporation; therefore, the Corporation recognized no adjustment for unrecognized income tax benefits for the years ended December 31, 2019 and 2018 . The Corporation’s policy is to recognize interest and penalties on unrecognized tax benefits in income taxes expense in the Consolidated Statement of Income. The tax years subject to examination by the taxing authorities are the years ended December 31, 2018 , 2017 , and 2016 . 
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the evaluation of other-than-temporary impairment losses for investment securities and the evaluation of impairment losses for foreclosed real estate.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in Note 16 – Fair Value Measurements and Fair Values of Financial Instruments. Fair value estimates involve uncertainties and matters of significant judgment. Changes in assumptions or in market conditions could significantly affect the estimates.
Goodwill and Core Deposit Intangible Assets	Goodwill and Core Deposit Intangible Assets Goodwill arising from acquisitions is not amortized, but is subject to an annual impairment test. This test consists of a qualitative analysis. If the Corporation determines events or circumstances indicate that it is more likely than not that goodwill is impaired, a quantitative analysis must be completed. Analyses may also be performed between annual tests. Significant judgment is applied when goodwill is assessed for impairment. This judgment includes developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables, incorporating general economic and market conditions, and selecting an appropriate control premium. The Corporation completes its annual goodwill impairment test on October 1 st of each year. Based upon the analysis, the Corporation concluded that the amount of recorded goodwill was not impaired as of October 1, 2019.  Core deposit intangibles represent the value assigned to demand, interest checking, money market, and savings accounts acquired as part of an acquisition. The core deposit intangible value represents the future economic benefit of potential cost savings from acquiring core deposits as part of an acquisition compared to the cost of alternative funding sources and the alternative cost to grow a similar core deposit base. The core deposit intangible asset resulting from the merger with Madison Bancorp, Inc. was determined to have a definite life and is being amortized using the sum of the years’ digits method over ten years. All intangible assets must be evaluated for impairment if certain events or changes in circumstances occur. Any impairment write-downs would be recognized as expense on the consolidated statements of income.  At December 31, 2019 , 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. Results for reporting periods beginning after January 1, 2018 are presented under ASC 606, while prior period amounts were not adjusted and continue to be reported in accordance with the previous accounting guidance under ASC 605.  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. The Corporation’s performance obligations are generally satisfied, and the related revenue recognized, over the period in which the service is provided. Payment for services rendered is primarily received in the following month.  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 in which case revenues are recognized utilizing the expected value method. Payment for services rendered is primarily received in the following month.  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. Other service charges include revenue from processing wire transfers, cashier’s checks and other services. Revenue is recognized when the performance obligation is completed which is generally monthly for account maintenance services or when a transaction has been completed. Payment for service charges on deposit accounts is primarily received immediately or in the following month through a direct charge to the customers’ accounts.  Other noninterest income – The Corporation evaluated individual components of other noninterest income, such as credit card merchant fees, credit and gift card fees and ATM fees. Debit card income is primarily comprised of interchange fees earned whenever the Corporation’s debit cards are processed through payment networks, such as Visa. Credit and gift card income is realized through a third party provider who issues credits as private label in the Corporation’s name. ATM fees are primarily generated when a non-Corporation cardholder uses a Corporation ATM. The income is primarily comprised as a percentage of interchange fees earned whenever the issuer’s card is processed through card payment networks, such as Visa or Pulse. Merchant services income is realized through a third party service provider who is contracted by the Corporation under a referral arrangement. Such fees represent fees charged to merchants to process their debit card transactions. The Corporation’s performance obligation for these fees are largely satisfied, and related revenue recognized, when the services are rendered or upon completion. Payment is typically received within a 1 to 3 day lag or in the following month.
Per Share Data	Per Share Data Basic net income per share is calculated as net income available to shareholders divided by the weighted average number of shares outstanding. Diluted net income per share is calculated as net income available to shareholders divided by the weighted average number of shares outstanding plus shares that would have been outstanding if dilutive potential shares had been issued, as well as any adjustment to income that would result from the assumed issuance. Potential shares that may be issued by the Corporation relate solely to outstanding stock options and are determined using the treasury stock method. All share and per share amounts are adjusted for stock dividends that are declared prior to the issuance of the consolidated financial statements.  The computation of net income per share for the years ended December 31, 2019 , 2018 and 2017 is provided in the table below.      (in thousands, except per share data) 2019 2018 2017  Net income available to shareholders $ 18,647 $ 19,542 $ 12,004   Weighted average shares outstanding (basic) 9,863 9,858 9,780  Effect of dilutive stock options 66 95 115  Weighted average shares outstanding (diluted) 9,929 9,953 9,895   Basic earnings per share $ 1.89 $ 1.98 $ 1.22  Diluted earnings per share $ 1.88 $ 1.96 $ 1.21   Anti-dilutive stock options excluded from the computation of earnings per share 32 35 18 
Stock-Based Compensation	Stock-Based Compensation The Corporation accounts for its stock-based compensation awards in accordance with FASB ASC Topic 718, which requires public companies to recognize compensation expense, related to stock-based compensation awards in their statements of operations. Compensation expense is equal to the fair value of the stock-based compensation awards on the grant date and is recognized over the vesting period of such awards. More information is provided in Note 12 – Stock-Based Compensation.
Cash Flow Information	Cash Flow Information For purposes of the statements of cash flows, the Corporation considers interest bearing deposits with banks, cash and due from banks, and federal funds sold to be cash and cash equivalents.  Supplemental cash flow information is provided in the table below.      Years ended December 31,  (dollars in thousands) 2019 2018 2017  Cash paid during the period for:  Income taxes $ 4,310 $ 4,605 $ 7,926  Interest $ 21,373 $ 16,191 $ 10,692   Noncash investing activities:  Transfer of loans to foreclosed real estate $ 0 $ 1,709 $ 216  Initial recognition of financing lease right-of-use assets $ 1,358 $ 0 $ 0  Initial recognition of financing lease liabilities $ 1,480 $ 0 $ 0  Initial recognition of operating lease right-of-use assets $ 2,958 $ 0 $ 0  Initial recognition of operating lease liabilities $ 3,035 $ 0 $ 0  Loans to facilitate sales of foreclosed real estate $ 0 $ 0 $ 2,310  Transfer of loans held for sale to held-to-maturity portfolio $ 0 $ 0 $ 228 
Off-Balance Sheet Financial Instruments	Off-Balance Sheet Financial Instruments In the ordinary course of business, the Corporation enters into off-balance sheet financial instruments consisting of commitments to extend credit and standby letters of credit. These financial instruments are recorded on the balance sheet when they become a receivable to the Corporation.
Comprehensive Income	Comprehensive Income and Accumulated Other Comprehensive Income Accounting principles generally accepted in the United States of America require that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities, such as unrealized gains and losses on available-for-sale securities, are reported as a separate component of the shareholders’ equity section of the balance sheet, such items, along with net income, are components of comprehensive income.
Segment Reporting	Segment Reporting Management has determined that it operates in only one segment, community banking. The Corporation’s non-banking activities are insignificant to the consolidated financial statements.
Recent Accounting Pronouncements	Recent Accounting Pronouncements  Pronouncements Adopted in 2019  In February 2016, the FASB issued ASU 2016-02, Leases and in July 2018 issued ASU 2018-10 and ASU 2018-11, Codification Improvements to Topic 842, 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 adopted the new standard effective January 1, 2019, which resulted in an increase in assets to recognize the present value of the lease obligations (right-of-use assets) with a corresponding increase in liabilities as discussed in Note 8-Leases. The adoption did not have an overall material impact on the Corporation’s consolidated financial statements of income. In July 2018, the FASB issued ASU 2018-07, Improvements to Nonemployee Share-Based Payment Accounting. This standard expands the scope of Topic 718, Compensation – Stock Compensation to include share-based payment transaction for acquiring goods and services from nonemployees. This standard requires application of Topic 718 to nonemployee awards for specific guidance on inputs to an option pricing model and the attribution of cost (that is, the period of time over which share-based payment awards vest and the pattern of cost recognition over that period). The amendments in the Update are effective for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. The Corporation adopted the new standard on January 1, 2019 and the adoption of this standard did not have a material impact on the Corporation’s consolidated financial statements.  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 January 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 August 2018, the FASB issued ASU 2018-13, Fair Value Measurement. The amendments in this update modify the disclosure requirements in Topic 820, Fair Value Measurement. The following disclosure requirements were removed: the amount of and reasons for transfers between Level 1 and Level 2, the policy for timing of transfers between levels, and the valuation processes for Level 3 fair value measurements. The following disclosure requirements were modified: for investments in certain entities that calculate net asset value, and entity is required to disclose the timing of liquidation of investee’s assets and the amendments clarify that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date. The following disclosure requirements were added: the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The update is effective for fiscal years beginning after December 15, 2019. The adoption of this update is not expected to have a material impact on its consolidated financial statements based on current circumstances.  In August 2018, the FASB issued ASU 2018-15, Intangibles-Goodwill and Other-Internal-Use Software. This standard aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with those incurred to develop or obtain internal-use software. This standard requires application of Subtopic 350-40 to determine which costs to implement the service contract would be capitalized as an asset and which costs would be expensed. The amendments in the update are effective for the years beginning after December 15, 2019. The adoption of this update is not expected to have a material impact on its consolidated financial statements based on current circumstances .  In August 2018, the FASB issued ASU 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20). The amendments in this update remove disclosures that are no longer considered cost beneficial, clarify the specific requirements of disclosures, and add disclosure requirements identified as relevant. The update is effective for fiscal years ending after December 15, 2020. Early adoption is permitted. The adoption of this update 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 was delayed and is now effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Corporation expects the provisions of ASU No. 2016-13 to impact the Corporation’s consolidated financial statements, in particular, the level of the reserve for credit losses. The Corporation is continuing to evaluate the extent of the potential impact and expects that portfolio composition and economic conditions at the time of adoption will be a factor.
