| SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies) | 12 Months Ended |
| Dec. 31, 2018 |
| Accounting Policies [Abstract] | |
| Consolidation, Policy [Policy Text Block] | Principles of Consolidation The consolidated financial statements include the accounts of First Keystone Corporation and its wholly-owned subsidiary, First Keystone Community Bank (the “Bank”). All significant inter-company balances and transactions have been eliminated in consolidation. |
| Nature of Operations [Policy Text Block] | Nature of Operations The Corporation, headquartered in Berwick, Pennsylvania, provides a full range of banking, trust and related services through its wholly-owned Bank subsidiary and is subject to competition from other financial institutions in connection with these services. The Bank serves a customer base which includes individuals, businesses, governments, and public and institutional customers primarily located in the Northeast Region of Pennsylvania. The Bank has 18 full service offices, one loan production office, and 20 Automated Teller Machines (“ATM”) located in Columbia, Luzerne, Montour, Monroe, and Northampton counties. The Corporation and its subsidiary must also adhere to certain federal and state banking laws and regulations and are subject to periodic examinations made by various state and federal agencies. |
| Segment Reporting, Policy [Policy Text Block] | Segment Reporting The Corporation’s subsidiary acts as an independent community financial services provider, and offers traditional banking and related financial services to individual, business, government, and public and institutional customers. Through its branch and ATM network, the Bank offers a full array of commercial and retail financial services, including the taking of time, savings and demand deposits; the making of commercial, consumer and mortgage loans; and the providing of other financial services. The Bank also performs personal, corporate, pension and fiduciary services through its Trust Department. Management does not separately allocate expenses, including the cost of funding loan demand, between the commercial, retail, trust and mortgage banking operations of the Corporation. As such, discrete financial information is not available and segment reporting would not be meaningful. |
| Concentration Risk, Credit Risk, Policy [Policy Text Block] | Significant Concentrations of Credit Risk The majority of the Corporation’s activities involve customers located primarily in Columbia, Luzerne, Montour, Monroe, Northampton, and Lehigh counties in Pennsylvania. The types of securities in which the Corporation invests are presented in Note 3 – Securities. Credit risk as it relates to investment activities is moderated through the monitoring of ratings and geographic concentrations residing in the portfolio and the observance of minimum rating levels in the investment policy. Note 4 – Loans and Allowance for Loan Losses summarizes the types of lending in which the Corporation engages. The inherent risks associated with lending activities are mitigated by adhering to conservative underwriting practices and policies, as well as portfolio diversification and thorough monitoring of the loan portfolio. It is management’s opinion that the investment and loan portfolios were well balanced at December 31, 2018, to the extent necessary to avoid any significant concentrations of credit risk. |
| Use of Estimates, Policy [Policy Text Block] | Use of Estimates The preparation of these consolidated financial statements, in conformity with accounting principles generally accepted in the United States of America, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of these consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant changes include the determination of other-than-temporary impairment on securities and the determination of the allowance for loan losses. |
| Subsequent Events, Policy [Policy Text Block] | Subsequent Events The Corporation has evaluated events and transactions occurring subsequent to the consolidated balance sheet date of December 31, 2018, for items that should potentially be recognized or disclosed in the consolidated financial statements. The evaluation was conducted through the date these consolidated financial statements were issued. |
| Cash and Cash Equivalents, Policy [Policy Text Block] | Cash and Cash Equivalents For purposes of reporting consolidated cash flows, cash and cash equivalents include cash on hand and due from banks, interest-bearing deposits in other banks, and federal funds sold. The Corporation considers cash classified as interest-bearing deposits with other banks as a cash equivalent since they are represented by cash accounts essentially on a demand basis and mature within one year. Federal funds are also included as a cash equivalent because they are generally purchased and sold for one-day periods. |
| Time Deposits with Other Banks [Policy Text Block] | Time Deposits with Other Banks Time deposits with other banks consist of fully insured certificates of deposit in other banks with maturity dates between one and five years. |
| Investment, Policy [Policy Text Block] | Securities The Corporation classifies its securities as either “Held-to-Maturity” or “Available-for-Sale” at the time of purchase. Securities are accounted for on a trade date basis. Debt securities are classified as Held-to-Maturity when the Corporation has the ability and positive intent to hold the securities to maturity. Securities classified as Held-to-Maturity are carried at cost adjusted for amortization of premium and accretion of discount to maturity. Debt securities not classified as Held-to-Maturity are included in the Available-for-Sale category and are carried at fair value. The amount of any unrealized gain or loss, net of the effect of deferred income taxes, is reported as accumulated other comprehensive (loss) income (AOCI) in the Consolidated Balance Sheets and Consolidated Statements of Changes in Stockholders’ Equity. Management’s decision to sell Available-for-Sale securities is based on changes in economic conditions controlling the sources and applications of funds, terms, availability of and yield of alternative investments, interest rate risk and the need for liquidity. The cost of debt securities classified as Held-to-Maturity or Available-for-Sale is adjusted for amortization of premiums and accretion of discounts to expected maturity. Such amortization and accretion, as well as interest and dividends, are included in interest and dividend income on investment securities. Realized gains and losses are included in net investment securities gains and losses. The cost of investment securities sold, redeemed or matured is based on the specific identification method. Beginning January 1, 2018, upon adoption of ASU 2016-01, equity securities with readily determinable fair values are stated at fair value with realized and unrealized gains and losses reported in income. For periods prior to January 1, 2018, equity securities were classified as available-for-sale and stated at fair value with unrealized gains and losses reported as a separate component of AOCI, net of tax. Equity securities without readily determinable fair values are recorded at cost less impairment, if any. Management evaluates securities for other-than-temporary impairment (“OTTI”) at least on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. Securities classified as available-for-sale or held-to-maturity are generally evaluated for OTTI under FASB ASC 320, Investments - Debt and Equity Securities . In determining OTTI under the FASB ASC 320 model, management considers many factors, including (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, (3) whether the market decline was affected by macroeconomic conditions, and (4) whether the entity has the intent to sell the debt security or more likely than not will be required to sell the debt security before its anticipated recovery. The assessment of whether an other-than-temporary decline exists involves a high degree of subjectivity and judgment and is based on the information available to management at a point in time. When other-than-temporary impairment occurs on debt securities, the amount of the other-than-temporary impairment recognized in earnings depends on whether an entity intends to sell the security or more likely than not will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss. If an entity intends to sell or more likely than not will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss, the other-than-temporary impairment shall be recognized in earnings equal to the entire difference between the investment’s amortized cost basis and its fair value at the balance sheet date. If an entity does not intend to sell the security and it is not more likely than not that the entity will be required to sell the security before recovery of its amortized cost basis less any current-period loss, the other-than-temporary impairment shall be separated into the amount representing the credit loss and the amount related to all other factors. The amount of the total other-than-temporary impairment related to the credit loss is determined based on the present value of cash flows expected to be collected, and the realized loss is recognized as impairment charges on securities on the Consolidated Statements of Income. The amount of the total other-than-temporary impairment related to the other factors shall be recognized in other comprehensive (loss) income, net of applicable taxes. The previous amortized cost basis less the other-than-temporary impairment recognized in earnings becomes the new amortized cost basis of the investment. The fair market value of the equity securities tends to fluctuate with the overall equity markets as well as the trends specific to each institution. The equity securities portfolio is reviewed in a similar manner as that of the debt securities with greater emphasis placed on the length of time the market value has been less than the carrying value and the financial sector outlook. The Corporation also reviews dividend payment activities, levels of non-performing assets and loan loss reserves. The starting point for the equity analysis is the length and severity of market value decline. The realized loss is recognized as impairment charges on securities on the Consolidated Statements of Income. The previous cost basis less the other-than-temporary impairment recognized in earnings becomes the new cost basis of the investment. |
| Restricted Investments [Policy Text Block] | Restricted Investment in Bank Stocks The Bank owns restricted stock investments in the Federal Home Loan Bank of Pittsburgh (“FHLB-Pittsburgh”) and Atlantic Community Bankers Bank (“ACBB”). These investments do not have a readily determinable fair value because their ownership is restricted and they can be sold back only to the FHLB-Pittsburgh, ACBB or to another member institution. Therefore, these investments are carried at cost. At December 31, 2018, the Corporation held $8,646,000 in stock of FHLB-Pittsburgh and $35,000 in stock of ACBB. At December 31, 2017, the Corporation held $4,023,000 in stock of FHLB-Pittsburgh and $35,000 in stock of ACBB. Management evaluates the restricted investment in bank stocks for impairment on an annual basis. Management’s determination of whether these investments are impaired is based on management’s assessment of the ultimate recoverability of the cost of these investments rather than by recognizing temporary declines in value. The following factors were evaluated to determine the ultimate recoverability of the cost of the Corporation’s restricted investment in bank stocks; (i) the significance of the decline in net assets of the correspondent bank as compared to the capital stock amount for the correspondent bank and the length of time this situation has persisted; (ii) commitments by the correspondent bank to make payments required by law or regulation and the level of such payments in relation to the operating performance of the correspondent bank; (iii) the impact of legislative and regulatory changes on the institutions and, accordingly, on the customer base of the correspondent bank; and (iv) the liquidity position of the correspondent bank. Based on the analysis of these factors, management determined that no impairment charge was necessary related to the restricted investment in bank stocks during 2018 or 2017. |
| Finance, Loans and Leases Receivable, Policy [Policy Text Block] | Loans Net loans are stated at their outstanding recorded investment, net of deferred fees and costs, unearned income and the allowance for loan losses. Interest on loans is recognized as income over the term of each loan, generally, by the accrual method. Loan origination fees and certain direct loan origination costs have been deferred with the net amount amortized using the straight line method or the interest method over the contractual life of the related loans as an interest yield adjustment. Residential mortgage loans held for sale are carried at the lower of cost or market on an aggregate basis determined by independent pricing from appropriate federal or state agency investors. These loans are sold without recourse. Loans held for sale amounted to $365,000 at December 31, 2018 and $834,000 at December 31, 2017. The loans receivable portfolio is segmented into commercial, residential and consumer loans. Commercial loans consist of the following classes: Commercial and Industrial and Commercial Real Estate. Commercial and Industrial Lending The Corporation originates commercial and industrial loans primarily to businesses located in its primary market area and surrounding areas. These loans are used for various business purposes, which include short-term loans and lines of credit to finance machinery and equipment, inventory and accounts receivable. Generally, the maximum term for loans extended on machinery and equipment is based on the projected useful life of such machinery and equipment. Most business lines of credit are written on demand and are reviewed annually. Commercial and industrial loans are generally secured with short-term assets; however, in many cases, additional collateral such as real estate is provided as additional security for the loan. Loan-to-value maximum thresholds have been established by the Corporation and are specific to the type of collateral. Collateral values may be determined using invoices, inventory reports, accounts receivable aging reports, business financial statements, collateral appraisals, etc. Commercial and industrial loans are typically secured by personal guarantees of the borrower. In underwriting commercial and industrial loans, an analysis is performed to evaluate the borrower's character and capacity to repay the loan, the adequacy of the borrower's capital and collateral, as well as the conditions affecting the borrower. Evaluation of the borrower's past, present and future cash flows is also an important aspect of the Corporation's analysis of the borrower’s ability to repay. Commercial and industrial loans generally present a higher level of risk than other types of loans due primarily to the effect of general economic conditions. Commercial and industrial loans are typically made on the basis of the borrower’s ability to make repayment from cash flows from the borrower’s primary business activities. As a result, the availability of funds for the repayment of commercial and industrial loans is dependent on the success of the business itself, which in turn, is likely to be dependent upon the general economic environment. Commercial Real Estate Lending The Corporation engages in commercial real estate lending in its primary market area and surrounding areas. The Corporation’s commercial real estate portfolio is secured primarily by commercial retail space, commercial office buildings, residential housing and hotels. Generally, commercial real estate loans have terms that do not exceed twenty years, have loan-to-value ratios of up to eighty percent of the value of the collateral property, and are typically secured by personal guarantees of the borrowers. In underwriting these loans, the Corporation performs a thorough analysis of the financial condition of the borrower, the borrower’s credit history, and the reliability and predictability of the cash flow generated by the property securing the loan. The value of the property is determined by either independent appraisers or internal evaluations by Bank officers. Commercial real estate loans generally present a higher level of risk than residential real estate secured loans. Repayment of loans secured by commercial real estate is typically dependent upon the successful operation of the related real estate project and/or the effect of the general economic conditions on income producing properties. Residential Real Estate Lending (Including Home Equity) The Corporation’s residential real estate portfolio is comprised of one-to-four family residential mortgage loan originations, home equity term loans and home equity lines of credit. These loans are generated by the Corporation’s marketing efforts, its present customers, walk-in customers and referrals. These loans originate primarily within or with customers from the Corporation’s market area. The Corporation’s one-to-four family residential mortgage originations are secured primarily by properties located in its primary market area and surrounding areas. The Corporation offers fixed-rate mortgage loans with terms up to a maximum of thirty years for both permanent structures and those under construction. Loans with terms of thirty years are normally held for sale and sold without recourse; most of the residential mortgages held in the Corporation’s residential real estate portfolio have maximum terms of twenty years. Generally, the majority of the Corporation’s residential mortgage loans originate with a loan-to-value of eighty percent or less, or those with primary mortgage insurance at ninety-five percent or less. Home equity term loans are secured by the borrower’s primary residence and typically have a maximum loan-to-value of eighty percent and a maximum term of fifteen years. In general, home equity lines of credit are secured by the borrower’s primary residence with a maximum loan-to-value of eighty percent and a maximum term of twenty years. In underwriting one-to-four family residential mortgage loans, the Corporation evaluates the borrower’s ability to make monthly payments, the borrower’s repayment history and the value of the property securing the loan. The ability and willingness to repay is determined by the borrower’s employment history, current financial conditions and credit background. A majority of the properties securing residential real estate loans made by the Corporation are appraised by independent appraisers. The Corporation generally requires mortgage loan borrowers to obtain an attorney’s title opinion or title insurance and fire and property insurance, including flood insurance, if applicable. Residential mortgage loans, home equity term loans and home equity lines of credit generally present a lower level of risk than consumer loans because they are secured by the borrower’s primary residence. Risk is increased when the Corporation is in a subordinate position, especially to another lender, for the loan collateral. Consumer Lending The Corporation offers a variety of secured and unsecured consumer loans, including vehicle loans, stock loans and loans secured by financial institution deposits. These loans originate primarily within or with customers from the market area. Consumer loan terms vary according to the type and value of collateral and creditworthiness of the borrower. In underwriting personal loans, a thorough analysis is performed regarding the borrower’s willingness and financial ability to repay the loan as agreed. The ability to repay is determined by the borrower’s employment history, current financial condition and credit background. Consumer loans may entail greater credit risk than residential real estate loans, particularly in the case of personal loans which are unsecured or are secured by rapidly depreciable assets, such as automobiles or recreational equipment. In such cases, repossessed collateral for a defaulted personal loan may not provide an adequate source of repayment of the outstanding loan balance as a result of the greater likelihood of damage, loss or depreciation. In addition, personal loan collections are dependent on the borrower’s continuing financial stability and therefore, are more likely to be affected by adverse personal circumstances. Furthermore, the application of various federal and state laws, including bankruptcy and insolvency laws, may limit the amount which can be recovered on such loans. |
| Delinquent Loans [Policy Text Block] | Delinquent Loans Generally, a loan is considered to be past-due when scheduled loan payments are in arrears 10 days or more. Delinquent notices are generated automatically when a loan is 10 or 15 days past-due, depending on loan type. Collection efforts continue on past-due loans that have not been brought current, when it is believed that some chance exists for improvement in the status of the loan. Past-due loans are continually evaluated with the determination for charge-off being made when no reasonable chance remains that the status of the loan can be improved. Commercial and Industrial and Commercial Real Estate loans are charged off in whole or in part when they become sufficiently delinquent based upon the terms of the underlying loan contract and when a collateral deficiency exists. Because all or part of the contractual cash flows are not expected to be collected, the loan is considered to be impaired, and the Bank estimates the impairment based on its analysis of the cash flows or collateral estimated at fair value less cost to sell. Residential Real Estate and Consumer loans are charged off when they become sufficiently delinquent based upon the terms of the underlying loan contract and when the value of the underlying collateral is not sufficient to support the loan balance and a loss is expected. At that time, the amount of estimated collateral deficiency, if any, is charged off for loans secured by collateral, and all other loans are charged off in full. Loans with collateral are charged down to the estimated fair value of the collateral less cost to sell. Loans in which the borrower is in bankruptcy are considered on a case by case basis and are either charged off or reaffirmed by the borrower. Generally, a loan is classified as non-accrual and the accrual of interest on such a loan is discontinued when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about further collectability of principal or interest, even though the loan may currently be performing. A loan may remain on accrual status if it is well secured (or supported by a strong guarantee) and in the process of collection. When a loan is placed on non-accrual status, unpaid interest credited to income in the current year is reversed and unpaid interest accrued in prior years is charged against interest income. Certain non-accrual loans may continue to perform; that is, payments are still being received. Generally, the payments are applied to principal. These loans remain under constant scrutiny, and if performance continues, interest income may be recorded on a cash basis based on management's judgment as to collectability of principal. |
| Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block] | Allowance for Loan Losses The allowance for loan losses is established through provisions for loan losses charged against income. Loans deemed to be uncollectible are charged against the allowance for loan losses and subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is maintained at a level estimated by management to be adequate to absorb potential loan losses. Management’s periodic evaluation of the adequacy of the allowance for loan losses 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 (including the timing of future payments), 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 including the amounts and timing of future cash flows expected to be received on impaired loans that may be susceptible to significant change. The allowance consists of specific, general and unallocated components. The specific component relates to loans that are individually classified as impaired. Select loans are not aggregated for collective impairment evaluation, as such; all loans are subject to individual impairment evaluation should the facts and circumstances pertinent to a particular loan suggest that such evaluation is necessary. Factors considered by management 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. Management 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. If a loan is impaired, a portion of the allowance may be allocated so that the loan is reported, net, at the present value of estimated future cash flows using the loan’s existing rate or at the fair value of collateral if repayment is expected solely from collateral. Troubled debt restructurings are separately identified for impairment disclosures and are measured at the present value of estimated future cash flows using the loan’s effective rate at inception. If a troubled debt restructuring is considered to be a collateral dependent loan, the loan may be reported, net, at the fair value of the collateral. For troubled debt restructurings that subsequently default, the Corporation determines the amount of reserve in accordance with the accounting policy for the allowance for loan losses. The general component covers all other loans not identified as impaired and is based on historical losses and qualitative factors. The historical loss component of the allowance is determined by losses recognized by portfolio segment over a time period that management has determined represents the current credit cycle. Qualitative factors impacting each portfolio segment may include: delinquency trends, loan volume trends, Bank policy changes, management processes and oversight, economic trends (including change in consumer and business disposable incomes, unemployment and under-employment levels, and other conditions), concentrations by industry or product, internal and external loan review processes, collateral value and market conditions, and external factors including regulatory issues and competition. The unallocated component of the allowance is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio. A reserve for unfunded lending commitments is provided for possible credit losses on off-balance sheet credit exposures. The reserve for unfunded lending commitments represents management’s estimate of losses inherent in its unfunded loan commitments and, if necessary, is recorded in other liabilities on the Consolidated Balance Sheets. As of December 31, 2018 and 2017 the amount of the reserve for unfunded lending commitments was $117,000 and $116,000, respectively. The Corporation is subject to periodic examination by its federal and state examiners, and may be required by such regulators to recognize additions to the allowance for loan losses based on their assessment of credit information available to them at the time of their examinations. A loan is considered impaired when, based on current information and events, it is probable that the Bank will be unable to collect all amounts due according to the contractual terms of the original loan agreement. Under current accounting standards, the allowance for loan losses related to impaired loans is based on discounted cash flows using the loan’s effective interest rate at inception or the fair value of the collateral for certain collateral dependent loans. The restructuring of a loan is considered a “troubled debt restructuring” if both the following conditions are met: (i) the borrower is experiencing financial difficulties, and (ii) the Bank has granted a concession. The most common concessions granted include one or more modifications to the terms of the debt, such as (a) a reduction in the interest rate for the remaining life of the debt, (b) an extension of the maturity date at an interest rate lower than the current market rate for new debt with similar risk, (c) a temporary period of interest-only payments, and (d) a reduction in the contractual payment amount for either a short period or remaining term of the loan. A less common concession is the forgiveness of a portion of the principal. The determination of whether a borrower is experiencing financial difficulties takes into account not only the current financial condition of the borrower, but also the potential financial condition of the borrower were a concession not granted. Similarly, the determination of whether a concession has been granted is very subjective in nature. For example, simply extending the term of a loan at its original interest rate or even at a higher interest rate could be interpreted as a concession unless the borrower could readily obtain similar credit terms from a different lender. Loans modified in a troubled debt restructuring are considered impaired and may or may not be placed on non-accrual status until the Bank determines the future collection of principal and interest is reasonably assured, which generally requires that the borrower demonstrates a period of performance according to the restructured terms of six months. The Bank utilizes a risk grading matrix as a tool for managing credit risk in the loan portfolio and assigns an asset quality rating (risk grade) to all Commercial and Industrial, Commercial Real Estate, Residential Real Estate and Consumer borrowings. An asset quality rating is assigned using the guidance provided in the Bank’s loan policy. Primary responsibility for assigning the asset quality rating rests with the lender. The asset quality rating is validated periodically by both an internal and external loan review process. The commercial loan grading system focuses on a borrower’s financial strength and performance, experience and depth of management, primary and secondary sources of repayment, the nature of the business and the outlook for the particular industry. Primary emphasis is placed on financial condition and trends. The grade also reflects current economic and industry conditions; as well as other variables such as liquidity, cash flow, revenue/earnings trends, management strengths or weaknesses, quality of financial information, and credit history. The loan grading system for Residential Real Estate and Consumer loans focuses on the borrower’s credit score and credit history, debt-to-income ratio and income sources, collateral position and loan-to-value ratio, as well as other variables such as current economic conditions, and individual strengths and weaknesses. Risk grade characteristics are as follows: Risk Grade 1 – MINIMAL RISK through Risk Grade 6 – MANAGEMENT ATTENTION (Pass Grade Categories) Risk is evaluated via examination of several attributes including but not limited to financial trends, strengths and weaknesses, likelihood of repayment when considering both cash flow and collateral, sources of repayment, leverage position, management expertise, and repayment history. At the low-risk end of the rating scale, a risk grade of 1 - Minimal Risk is the grade reserved for loans with exceptional credit fundamentals and virtually no risk of default or loss. Loan grades then progress through escalating ratings of 2 through 6 based upon risk. Risk Grade 2 - Modest Risk are loans with sufficient cash flows; Risk Grade 3 - Average Risk are loans with key balance sheet ratios slightly above the borrower’s peers; Risk Grade 4 - Acceptable Risk are loans with key balance sheet ratios usually near the borrower’s peers, but one or more ratios may be higher; and Risk Grade 5 – Marginally Acceptable are loans with strained cash flow, increasing leverage and/or weakening markets. Risk Grade 6 - Management Attention are loans with weaknesses resulting from declining performance trends and the borrower’s cash flows may be temporarily strained. Loans in this category are performing according to terms, but present some type of potential concern. Risk Grade 7 − SPECIAL MENTION (Non-Pass Category) Generally, these loans or assets are currently protected, but are “potentially weak.” They constitute an undue and unwarranted credit risk but not to the point of justifying a classification of substandard. Assets in this category are currently protected but have potential weakness which may, if not checked or corrected, weaken the asset or inadequately protect the Bank’s credit position at some future date. No loss of principal or interest is envisioned; however, they constitute an undue credit risk that may be minor but is unwarranted in light of the circumstances surrounding a specific asset. Risk is increasing beyond that at which the loan originally would have been granted. Historically, cash flows are inconsistent; financial trends show some deterioration. Liquidity and leverage are above industry averages. Financial information could be incomplete or inadequate. A Special Mention asset has potential weaknesses that deserve management’s close attention. Risk Grade 8 − SUBSTANDARD (Non-Pass Category) Generally, these assets are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified must have “well-defined” weaknesses that jeopardize the full liquidation of the debt. These loans are characterized by the distinct possibility that the Bank will sustain some loss if the aggregate amount of substandard assets is not fully covered by the liquidation of the collateral used as security. Substandard loans have a high probability of payment default and require more intensive supervision by Bank management. Risk Grade 9 − DOUBTFUL (Non-Pass Category) Generally, loans graded doubtful have all the weaknesses inherent in a substandard loan with the added factor that the weaknesses are pronounced to a point whereby the basis of current information, conditions, and values, collection or liquidation in full is deemed to be highly improbable. The possibility of loss is extremely high, but because of certain important and reasonably specific pending factors that may work to strengthen the asset, its classification is deferred until, for example, a proposed merger, acquisition, liquidation procedure, capital injection, perfection of liens on additional collateral and/or refinancing plan is completed. Loans are graded doubtful if they contain weaknesses so serious that collection or liquidation in full is questionable. |
| Property, Plant and Equipment, Policy [Policy Text Block] | Premises and Equipment Premises, improvements, and equipment are stated at cost less accumulated depreciation computed principally utilizing the straight-line method over the estimated useful lives of the assets. Long-lived assets are reviewed for impairment whenever events or changes in business circumstances indicate that the carrying value may not be recovered. Maintenance and minor repairs are charged to operations as incurred. The cost and accumulated depreciation of the premises and equipment retired or sold are eliminated from the property accounts at the time of retirement or sale, and the resulting gain or loss is reflected in current operations. |
| Servicing Asset [Policy Text Block] | Mortgage Servicing Rights The Corporation originates and sells real estate loans to investors in the secondary mortgage market. After the sale, the Corporation may retain the right to service these loans. The mortgage loans sold and serviced for others are not included in the Consolidated Balance Sheets. The unpaid principal balances of mortgage loans serviced for others were $97,201,000 and $100,179,000 at December 31, 2018 and 2017, respectively. When originated mortgage loans are sold and servicing is retained, a servicing asset is capitalized based on relative fair value at the date of the sale. Servicing assets are amortized as an offset to other fees in proportion to, and over the period of, estimated net servicing income. The servicing asset is included in other assets in the Consolidated Balance Sheets and amounted to $316,000 at December 31, 2018 and $379,000 at December 31, 2017. The amount of servicing income earned was $247,000 and $246,000 at December 31, 2018 and 2017, respectively. Amortization recognized in relation to mortgage servicing rights was $129,000 and $135,000 at December 31, 2018 and 2017, respectively. Both income and amortization are included in service charges and fees on the Consolidated Statements of Income. Gains or losses on sales of mortgage loans are recognized based on the differences between the selling price and the carrying value of the related mortgage loans sold. |
| Life Settlement Contracts, Policy [Policy Text Block] | Bank Owned Life Insurance The cash surrender value of bank owned life insurance is carried as an asset, and changes in cash surrender value are recorded as non-interest income. The Bank entered into agreements to provide post-retirement benefits to two retired employees in the form of life insurance payable to the employee’s beneficiaries upon their death through endorsement split dollar life insurance arrangements. The Bank’s accrued liabilities for this benefit agreement as of December 31, 2018 and 2017 was $40,000 and $41,000, respectively. The related expense for this benefit agreement amounted to $(1,000) for the years ended December 31, 2018 and 2017. |
| Interest in Unincorporated Joint Ventures or Partnerships, Policy [Policy Text Block] | Investments in Low-Income Housing Partnerships The Bank is a limited partner in real estate ventures that own and operate affordable residential low-income housing apartment buildings for elderly and mentally challenged adult residents. The investments are accounted for under the cost method. Under the cost method, the Bank recognizes tax credits as they are allocated and amortizes the initial cost of the investment over the period that the tax credits are allocated to the Bank. The amount of tax credits allocated to the Bank were $405,000 in 2018 and $323,000 in 2017, and the amortization of the investments in the limited partnerships were $530,000 and $181,000 in 2018 and 2017, respectively. During 2015, the Bank became a limited partner in a real estate venture with an initial investment of $590,000, and additional capital contributions of $1,178,000 made in 2016 and $252,000 made in 2017. The construction was completed and the property was occupied in 2017. |
| Goodwill and Intangible Assets, Policy [Policy Text Block] | Goodwill and Core Deposit Intangibles Goodwill resulted from the acquisition of the Pocono Community Bank in November 2007 and of certain fixed and operating assets acquired and deposit liabilities assumed of the branch of another financial institution in Danville, Pennsylvania, in January 2004. Such goodwill represents the excess cost of the acquired assets relative to the assets fair value at the dates of acquisition. During the first quarter of 2008, $152,000 of liabilities related to the Pocono acquisition were recorded as a purchase accounting adjustment resulting in an increase in the excess purchase price. The amount was comprised of the finalization of severance agreements and contract terminations related to the acquisition. In accordance with current accounting standards, goodwill is not amortized. Management performs an annual evaluation for impairment. Any impairment of goodwill results in a charge to income. The Corporation periodically assesses whether events or changes in circumstances indicate that the carrying amounts of goodwill and other intangible assets may be impaired. Goodwill is evaluated for impairment at the reporting unit level and an impairment loss is recorded to the extent that the carrying amount of goodwill exceeds its implied fair value. The Corporation has evaluated the goodwill included in its consolidated balance sheet at September 30, 2018, and has determined there was no impairment as of that date. In addition, the Corporation did not identify any impairment in 2017. No assurance can be given that future impairment tests will not result in a charge to earnings. Intangible assets are comprised of core deposit intangibles and premium discount (negative premium) on certificates of deposit acquired. The core deposit intangible was being amortized over the average life of the deposits acquired as determined by an independent third party. Premium discount (negative premium) on acquired certificates of deposit resulted from the valuation of certificate of deposit accounts by an independent third party. The book value of certificates of deposit acquired was greater than their fair value at the date of acquisition which resulted in a negative premium due to higher cost of the certificates of deposit compared to the cost of similar term financing. The core deposit intangible was subject to impairment testing whenever events or changes in circumstances indicate its carrying amount may not reflect its benefit. As of June 30, 2015, the core deposit intangible was fully amortized. |
| Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block] | Stock Based Compensation The Corporation adopted a stock option incentive plan in 1998. Compensation cost is recognized for stock options to employees based on the fair value of these awards at the date of grant. A Black-Scholes Option Pricing Model is utilized to estimate the fair value of stock options. Compensation expense is recognized over the requisite service period. The Plan expired in 2008, and therefore, no stock options are available for issuance. After adjustments for the effects of stock dividends, options exercised and options forfeited, there are no exercisable options issued and outstanding as of December 31, 2018. |
| Loans and Leases Receivable, Real Estate Acquired Through Foreclosure, Policy [Policy Text Block] | Foreclosed Assets Held for Resale Real estate properties acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at fair value less costs to sell on the date of foreclosure establishing a new cost basis. After foreclosure, valuations are periodically performed and if fair value less costs to sell declines subsequent to foreclosure, a valuation allowance is recorded through expense. Revenues derived from and costs to maintain the assets and subsequent gains and losses on sales are included in non-interest expense on the Consolidated Statements of Income. |
| Income Tax, Policy [Policy Text Block] | Income Taxes The Corporation accounts for income taxes in accordance with income tax accounting guidance FASB ASC Topic 740, Income Taxes. Current income tax accounting guidance results in two components of income tax expense: current and deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over revenues. The Corporation determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur. Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are reduced by a valuation allowance if, based on the weight of the evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized. The Corporation accounts for uncertain tax positions if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term more-likely-than-not means a likelihood of more than 50%; the terms examined and upon examination also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50% likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances, and information available at the reporting date and is subject to management’s judgment. The Corporation recognizes interest and penalties on income taxes, if any, as a component of income tax expense. |
| Earnings Per Share, Policy [Policy Text Block] | Earnings Per Share Basic earnings per share (“EPS”) is computed by dividing net income by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the Corporation. Potential common shares that may be issued by the Corporation relate solely to outstanding stock options and are determined using the treasury stock method. The following table sets forth the computation of basic and diluted earnings per share. (In thousands, except earnings per share) Year Ended December 31, 2018 2017 Net income $ 9,211 $ 8,648 Weighted-average common shares outstanding 5,737 5,689 Basic earnings per share $ 1.60 $ 1.52 Weighted-average common shares outstanding 5,737 5,689 Common stock equivalents due to effect of stock options — — Total weighted-average common shares and equivalents 5,737 5,689 Diluted earnings per share $ 1.60 $ 1.52 |
| Treasury Stock [Policy Text Block] | Treasury Stock The purchase of the Corporation’s common stock is recorded at cost. At the date of subsequent reissue, the treasury stock account is reduced by the cost of such stock on a first-in-first-out basis. |
| Trust Assets And Income [Policy Text Block] | Trust Assets and Revenues Property held by the Corporation in a fiduciary or agency capacity for its customers is not included in the accompanying consolidated financial statements since such items are not assets of the Corporation. Assets held in Trust were $105,917,000 and $111,130,000 at December 31, 2018 and 2017, respectively. Trust Department income is generally recognized on a cash basis and is not materially different than if it were reported on an accrual basis. |
| Comprehensive Income, Policy [Policy Text Block] | Comprehensive Income (Loss) The Corporation is required to present accumulated other comprehensive income (loss) in a full set of general-purpose financial statements for all periods presented. Accumulated other comprehensive income (loss) is comprised of net unrealized holding gains (losses) on the available-for-sale securities portfolio. The Corporation has elected to report these effects on the Consolidated Statements of Comprehensive Income. |
| Advertising Costs, Policy [Policy Text Block] | Advertising Costs It is the Corporation’s policy to expense advertising costs in the period in which they are incurred. |
| New Accounting Pronouncements, Policy [Policy Text Block] | Recent Accounting Standards Updates (“ASU”) – Adopted: Except as disclosed below, there were no new accounting pronouncements affecting the Corporation during the year ended December 31, 2018 that were not already adopted by the Corporation in previous periods. On January 1, 2018, the Corporation adopted ASU 2014-09, Revenue from Contracts with Customers, and all subsequent amendments to the ASU (collectively “ASC 606”), which (i) creates a single framework for recognizing revenue from contracts with customers that fall within its scope and (ii) revises when it is appropriate to recognize a gain (loss) from the transfer of nonfinancial assets, such as OREO. The majority of the Corporation’s revenue comes from interest income, including loans and securities, which are outside the scope of ASC 606. The Corporation’s services that fall within the scope of ASC 606 are presented within other income on the consolidated statements of income and are recognized as revenue as the Corporation satisfies its obligation to the customer. Services within the scope of ASC 606 include deposit related fees and service charges, interchange fees and surcharges, and income from wealth management activities. ASC 606 did not result in a change to the accounting for any in-scope revenue streams; as such, no cumulative effect adjustment was recorded. New disclosures required by the ASU are included in Note 18, “Revenue Recognition”. On January 1, 2018, the Corporation adopted ASU 2016-01, Financial Instruments-Overall (Topic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities, which amended the guidance on the classification and measurement of financial instruments. Adoption of ASU 2016-01 resulted in: (1) separate classification of marketable equity securities previously included in investment securities available-for-sale on the consolidated balance sheets, (2) changes in the fair value of the equity securities being captured in the consolidated statements of income and (3) an increase in retained earnings and corresponding decrease in accumulated other comprehensive loss of $634,000 at January 1, 2018 for the after-tax impact of the change in accounting for the unrealized gain on the equity securities. Adoption of the standard also resulted in the use of an exit price to determine the fair value of financial instruments not measured at fair value in the consolidated balance sheets. For more information about fair value disclosures, refer to Note 17, “Fair Value Measurements”. In August 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-15 – Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force). ASU No. 2016-15 addresses eight cash flow issues with specific guidance on how certain cash receipts and cash payments should be presented on the statement of cash flows. ASU No. 2016-15 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2017. The adoption of ASU No. 2016-15 in 2018 had no material effect on the Corporation’s cash flows. In November 2016, the Financial Accounting Standards Board ("FASB") issued ASU No. 2016-18, Statement of Cash Flows-Restricted Cash (Topic 230) . The amendments in this Update clarify the inclusion of restricted cash in the cash and cash equivalents beginning-of-period and end-of period reconciliation on the consolidated statement of cash flows. For public business entities that are SEC filers, such as the Corporation, the amendments in this Update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The implementation of this ASU in 2018 had no material effect on the Corporation’s cash flows. In March 2017, the Financial Accounting Standards Board (“FASB”) issued ASU 2017-07, Compensation - Retirement Benefits (Topic 715) : Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The amendments apply to all entities that offer employees defined benefit pension plans, other postretirement benefit plans, or other types of benefits accounted for under Topic 715, Compensation — Retirement Benefits. The amendments require that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. The amendments also allow only the service cost component to be eligible for capitalization when applicable (e.g., as a cost of internally manufactured inventory or a self-constructed asset). The ASU is effective for public business entities for annual periods beginning after December 15, 2017, including interim periods within those annual periods. The adoption of this update in 2018 had no material impact on the Corporation’s consolidated financial position or results of operations. In February 2018, the Financial Accounting Standards Board (“FASB”) issued ASU 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“AOCI”). This ASU provides financial statement preparers with an option to reclassify stranded tax effects within AOCI to retained earnings in each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act (or portion thereof) are recorded. Effective for all organizations for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. Organizations should apply the amendments either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recognized. The Corporation elected to early adopt this standard update, effective January 1, 2018. Adoption resulted in a reclassification between retained earnings and accumulated other comprehensive loss of $360,000 at January 1, 2018, which is included in the consolidated statements of changes in stockholders’ equity. Pending ASUs: In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , respectively, on its Consolidated Balance Sheets, with no expected adjustment to stockholders’ equity and no material impact to its consolidated statements of income. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU No. 2016-13 requires financial assets measured at amortized cost to be presented at the net amount expected to be collected, through an allowance for credit losses that is deducted from the amortized cost basis. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. ASU No. 2016-13 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2019. Early adoption is permitted for annual and interim periods beginning after December 15, 2018. While the Corporation is currently evaluating the provisions of ASU 2016-13 to determine the potential impact of the new standard will have on the Corporation’s Consolidated Financial Statements, it has taken steps to prepare for the implementation when it becomes effective, such as: forming an internal committee, gathering pertinent data, consulting with outside professionals, and subscribed to a new software system. In January 2017, the Financial Accounting Standards Board (“FASB”) issued ASU 2017-04, Intangibles – Goodwill and Other (Topic 350) : Simplifying the Test for Goodwill Impairment. The ASU simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. Instead, under the amendments, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value with its carrying amount. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount when measuring the goodwill impairment loss, if applicable. The update also eliminated the requirements for zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. The amendments are effective for public business entities for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of this update is not expected to have a material impact on the Corporation’s consolidated financial position or results of operations. In March 2017, the Financial Accounting Standards Board (“FASB”) issued ASU 2017-08, Receivables- Nonrefundable Fees and Other Costs (Subtopic 310-20) : Premium Amortization on Purchased Callable Debt Securities. In August 2018, The Financial Accounting Standards Board (“FASB”) issued ASU 2018-13, Fair Value Measurement (Topic 820) – Disclosure Framework – Changes to Disclosure Requirements for Fair Value Measurement. The amendments in this Update removed required disclosures regarding as follows: 1. The amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, 2. The policy for timing of transfers between levels, 3. The valuation processes for Level 3 fair value measurements, and 4. The Update modified the disclosure requirements on fair value measurements in Topic 820: 1. The changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and 2. The range and weighted average significant unobservable inputs used to develop Level 3 fair value measurements. For certain unobservable inputs, an entity may disclose other quantitative information (such as the median or arithmetic average) in lieu of the weighted average if the entity determines that other quantitative information would be a more reasonable and rational method to reflect the distribution of unobservable inputs used to develop Level 3 fair value measurements. The amendments in this Update are effective for all entities for fiscal years, and interim periods within those fiscal years beginning after December 15, 2019. An entity is permitted to early adopt any removed or modified disclosures upon issuance of this Update and delay adoption of the additional disclosures until their effective date. The Corporation will be assessing the impact that this guidance will have on its consolidated financial statements and related disclosures. |
| Transfers and Servicing of Financial Assets, Policy [Policy Text Block] | Transfer of Financial Assets Transfers of financial assets are accounted for as sales when control over 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. |
| Off-Balance-Sheet Credit Exposure, Policy [Policy Text Block] | Off-Balance Sheet Financial Instruments In the ordinary course of business, the Bank has entered into off-balance sheet financial instruments consisting of commitments to extend credit and letters of credit. Such financial instruments are recorded in the Consolidated Balance Sheets when they are funded. |
| Reclassification, Policy [Policy Text Block] | Reclassifications Certain amounts previously reported have been reclassified, when necessary, to conform with presentations used in the 2018 consolidated financial statements. Such reclassifications have no effect on the Corporation’s net income. |
