Significant Accounting Policies [Text Block]	1 NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES BASIS OF CONSOLIDATION - December 2018, NATURE OF OPERATIONS - The Corporation provides Trust and Financial Management services, including administration of trusts and estates, retirement plans, and other employee benefit plans, and investment management services. The Corporation offers a variety of personal and commercial insurance products through C&N Financial Services Corporation. C&N Financial Services Corporation also offers mutual funds, annuities, educational savings accounts and other investment products through registered agents. Management has determined that the Corporation has one The Corporation is subject to competition from other financial institutions. It is also subject to regulation by certain federal and state agencies and undergoes periodic examination by those regulatory authorities. As a consequence, the Corporation’s business is particularly susceptible to being affected by future federal and state legislation and regulations. USE OF ESTIMATES - Material estimates that are particularly susceptible to change include: ( 1 2 3 not 4 5 INVESTMENT SECURITIES - Available-for-sale debt securities - not may may Other-than-temporary impairment 1 2 3 4 not Marketable equity security Restricted equity securities LOANS HELD FOR SALE LOANS RECEIVABLE - The loans receivable portfolio is segmented into residential mortgage, commercial and consumer loans. The residential mortgage segment includes the following classes: first Loans are placed on nonaccrual status for all classes of loans when, in the opinion of management, collection of interest is doubtful. Any unpaid interest previously accrued on those loans is reversed from income. Interest income is not six no ALLOWANCE FOR LOAN LOSSES no 120 The allowance for loan losses is maintained at a level considered adequate to provide for losses that can be reasonably anticipated. Management 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 may may December 31, 2018 2017, no The allowance consists primarily of two 1 2 The specific component relates to loans that are classified as impaired based on a detailed assessment of certain larger loan relationships evaluated by a management committee referred to as the Watch List Committee. Specific loan relationships are identified for evaluation based on the related credit risk rating. For individual loans classified as impaired, an allowance is established when the collateral value less estimated selling costs, present value of 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 not three The qualitative factors used in the general component calculations are designed to address credit risk characteristics associated with each segment. The Corporation’s credit risk associated with all of the segments is significantly impacted by these factors, which include economic conditions within its market area, the Corporation’s lending policies, changes or trends in the portfolio, risk profile, competition, regulatory requirements and other factors. Further, the residential mortgage segment is significantly affected by the values of residential real estate that provide collateral for the loans. The majority of the Corporation’s commercial segment loans (approximately 53% December 31, 2018) Loans are classified as 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 by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not For commercial loans secured by real estate, estimated fair values are determined primarily through third For commercial and industrial 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 data 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. Loans whose terms are modified are classified as troubled debt restructurings if the Corporation grants such borrowers concessions and it is deemed that those borrowers are experiencing financial difficulty. Concessions granted under a troubled debt restructuring generally involve reductions in required payments, an extension of a loan’s stated maturity date or a temporary reduction in interest rate. Loans classified as troubled debt restructurings are designated as impaired. Nonaccrual troubled debt restructurings may not six BANK PREMISES AND EQUIPMENT IMPAIRMENT OF LONG-LIVED ASSETS may not may may not FORECLOSED ASSETS HELD FOR SALE GOODWILL AND CORE DEPOSIT INTANGIBLE ASSETS - may may not SERVICING RIGHTS INCOME TAXES not no STOCK COMPENSATION PLANS The fair value of each stock option is estimated on the date of grant using the Black-Scholes-Merton option valuation model.

Consolidation, Policy [Policy Text Block]	BASIS OF CONSOLIDATION - December 2018,
Nature of Operations, Policy [Policy Text Block]	NATURE OF OPERATIONS - The Corporation provides Trust and Financial Management services, including administration of trusts and estates, retirement plans, and other employee benefit plans, and investment management services. The Corporation offers a variety of personal and commercial insurance products through C&N Financial Services Corporation. C&N Financial Services Corporation also offers mutual funds, annuities, educational savings accounts and other investment products through registered agents. Management has determined that the Corporation has one The Corporation is subject to competition from other financial institutions. It is also subject to regulation by certain federal and state agencies and undergoes periodic examination by those regulatory authorities. As a consequence, the Corporation’s business is particularly susceptible to being affected by future federal and state legislation and regulations.

Finance, Loans and Leases Receivable, Policy [Policy Text Block]	LOANS RECEIVABLE - The loans receivable portfolio is segmented into residential mortgage, commercial and consumer loans. The residential mortgage segment includes the following classes: first Loans are placed on nonaccrual status for all classes of loans when, in the opinion of management, collection of interest is doubtful. Any unpaid interest previously accrued on those loans is reversed from income. Interest income is not six no
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	ALLOWANCE FOR LOAN LOSSES no 120 The allowance for loan losses is maintained at a level considered adequate to provide for losses that can be reasonably anticipated. Management 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 may may December 31, 2018 2017, no The allowance consists primarily of two 1 2 The specific component relates to loans that are classified as impaired based on a detailed assessment of certain larger loan relationships evaluated by a management committee referred to as the Watch List Committee. Specific loan relationships are identified for evaluation based on the related credit risk rating. For individual loans classified as impaired, an allowance is established when the collateral value less estimated selling costs, present value of 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 not three The qualitative factors used in the general component calculations are designed to address credit risk characteristics associated with each segment. The Corporation’s credit risk associated with all of the segments is significantly impacted by these factors, which include economic conditions within its market area, the Corporation’s lending policies, changes or trends in the portfolio, risk profile, competition, regulatory requirements and other factors. Further, the residential mortgage segment is significantly affected by the values of residential real estate that provide collateral for the loans. The majority of the Corporation’s commercial segment loans (approximately 53% December 31, 2018) Loans are classified as 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 by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not For commercial loans secured by real estate, estimated fair values are determined primarily through third For commercial and industrial 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 data 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. Loans whose terms are modified are classified as troubled debt restructurings if the Corporation grants such borrowers concessions and it is deemed that those borrowers are experiencing financial difficulty. Concessions granted under a troubled debt restructuring generally involve reductions in required payments, an extension of a loan’s stated maturity date or a temporary reduction in interest rate. Loans classified as troubled debt restructurings are designated as impaired. Nonaccrual troubled debt restructurings may not six
